PART I.

ITEM 1. Business.

Organization

EMCORE Corporation, together with its subsidiaries (referred to herein as the “Company,” “we,” “our,” or “EMCORE”), was established in 1986 as a New Jersey corporation. We became publicly traded in 1997 and are listed on the Nasdaq Stock Exchange under the ticker symbol EMKR. Our headquarters and principal executive offices are located in Budd Lake, New Jersey. For specific information about products or the markets served please visit our website at https://www.emcore.com. The information contained in or linked to our website is not a part of, nor incorporated by reference into, this Annual Report on Form 10-K or a part of any other report or filing with the SEC.

Description of the Business

We are a leading provider of sensors and navigation systems for the aerospace and defense market. We leverage

industry-leading Photonic Integrated Chip (“PIC”) and Quartz Micro Electro-Mechanical System (“QMEMS”) chip-level

technology to deliver state-of-the-art component and system-level products across our end-market applications. Over the last six years, EMCORE has expanded its scope and portfolio of inertial sensor products through the acquisitions of Systron Donner Inertial, Inc. (“SDI”) in June 2019, the Space and Navigation (“S&N”) business of L3Harris Technologies, Inc. (“L3Harris”) in April 2022, and the Fiber Optic Gyroscope (“FOG”) and Inertial Navigation Systems business (“EMCORE Chicago”) of KVH Industries, Inc. in August 2022. Our multi-year transition from a broadband company to an inertial navigation company has now been completed following the sales of (i) our cable TV, wireless, sensing and defense optoelectronics business lines in October 2023 and (ii) our chips business line and indium phosphide wafer fabrication operations in April 2024.

We have fully vertically-integrated manufacturing capability at our facilities in Budd Lake, NJ, Concord, CA, and Tinley Park, IL. These facilities support our manufacturing strategy for FOG, Ring Laser Gyro (“RLG”), PIC, and QMEMS products for inertial navigation. Our manufacturing facilities maintain ISO 9001 quality management certification, and we are AS9100 aerospace quality certified at our facilities in Concord, CA and Budd Lake, NJ. Our best-in-class components and systems support a broad array of inertial navigation applications.

Principal Products and Markets

We have one reporting segment, Inertial Navigation, whose product technology categories include: (a) FOG, (b) QMEMS, and (c) RLG, in each case which serves the aerospace and defense market.

Through our vertically-integrated infrastructure, we have adapted the same technologies, chip designs, and production assets applicable to our former cable TV products to our closed-loop FOG products. EMCORE’s patented PIC significantly advances FOG technology in our open-loop FOG products with a planar optical chip that replaces individual fiber optic components for easy integration and outstanding repeatability unit-to-unit. Our SDI QMEMS technology uses a one-piece, inertial sensing element to measure angular rotational velocity and is micro-machined using sophisticated photolithographic processes which are at the forefront of Micro Electro Mechanical System (“MEMS”) technology. Our advanced RLG technology delivers high performance, reliability, and quality pointing and position capability for land navigation and is deployed on key programs including the Multiple Launch Rocket System (“MLRS”) and High-Mobility Artillery Rocket System (“HIMARS”). These technologies have broad applications within the aerospace and defense markets for high-value-added products for land, sea, air, and space navigation.

FOG - Our FOG technologies have received multiple U.S. patents and have been qualified for several key military programs for applications including unmanned aerial systems, line-of-site stabilization, aviation, and aeronautics. Our FOG products range from tactical to navigation grade gyros, inertial measurement units (“IMU”) and inertial navigation systems (“INS”) where performance specifications improve depending on the grade, giving customers the flexibility to choose the product and performance level that best meets their application. Our FOG-based IMUs can deliver performance up to strategic grade and along with our INS provide compelling size, weight, and power (“SWaP”) performance compared to competing units and legacy designs to deliver high precision and better performance in compact, portable form factors.

Table of Contents

QMEMS - Our QMEMS gyroscopes, accelerometers, IMUs, and INS products deliver SWaP performance and cost advantages over alternative technologies. With our experience in these technologies, we are developing leading-edge disciplines which are enabling advanced performance capabilities in mission-critical applications worldwide. Our QMEMS products have no moving parts, no friction, no known modes of wear out, and require no recalibration or rebuilding. They deliver industry-leading reliability under demanding conditions through dedicated engineering technology and manufacturing operations excellence. Our QMEMS products provide precision system solutions and establish high standards for price and/or performance characteristics across guidance, navigation, control, pointing, and stabilization applications in commercial and military aircraft, unmanned autonomous vehicles, land vehicles, precision-guided weapons, and industrial and marine platforms.

RLG - Our line of INS includes the advanced RLG-based products of S&N, which provide increased performance, reliability, and quality pointing and position capability for land navigation systems including Artillery/Radar Positioning & Pointing Systems and Battlefield/Artillery Survey Systems. Partnered with the U.S. Army and deployed on key programs including the MLRS and HIMARS, our combat-proven precision RLG product family delivers mission-critical information such as survey, pointing, and position to the U.S. military for precise, indirect mass fire and counter-fire operations.

Strategic Plan

Our strategy is to continue pioneering development of inertial sensing and navigation systems serving the aerospace and defense market. We aim to design and build innovative products that are valued by our customers with the intention to grow our product line using innovative technology. We seek solutions that maximize performance in transformative aerospace and defense systems.

Our industry is characterized by rapid changes in process technologies with increasing levels of functional integration. Research and development efforts focus on maintaining our technological competitive edge to improve the quality and features of existing products. We strive to design new proprietary production technologies and products, improving the performance of existing materials, components, and subsystems, and reducing costs in the product manufacturing process. Many projects have focused on developing lower-cost versions of our existing products. In view of the high cost of development, we solicit research and development contracts that provide opportunities to enhance our core technology base and promote the commercialization of targeted products.

Distribution Methods

We sell products worldwide through multiple channels made up of our direct sales force, application engineers, third-party sales representatives, and distributors. Our sales force is aligned according to product line to maximize expertise. We communicate with customers’ engineering, manufacturing, and purchasing personnel throughout the sales cycle to provide optimized customer solutions through product design, qualifications, performance, and price. As a result, we develop strategic and long-lasting customer relationships with tailored products and services. Marketing efforts are focused on increasing brand awareness, communicating our technological advantages, and generating leads. We use a variety of marketing methods including our website and e-marketing, participation at trade shows, press releases and media relations, selective advertising, and social media to achieve these goals.

Competitive Business Conditions, Our Competitive Position in the Industry, and Methods of Competition

The markets we serve are extremely competitive and characterized by rapid technological change. Primary competitive factors are product cost, yield, throughput, performance, reliability, breadth of product line, product reputation, customer satisfaction, and customer loyalty to competitors’ technologies. We face competition from numerous domestic and international companies, who may have significant engineering, manufacturing, marketing, and financial resources. In addition, competitors may develop enhancements to, or future generations of, products that offer superior price and performance characteristics.

Although our markets are competitive, there are substantial barriers to entry. These barriers include significant dependence on existing patents, the time and costs required to develop products, the technical difficulty in manufacturing semiconductor-based products, the lengthy sales and qualification cycles, and the difficulties in hiring and retaining skilled employees with the required scientific and technical backgrounds.

We sell products to current and potential future competitors. As the markets for our products grow, new competitors are likely to emerge and current competitors may increase their market share. In the European Union (“EU”) and certain countries throughout the world, political and legal arrangements encourage the purchase of domestically produced goods which places us at a disadvantage in those regions or countries.

Table of Contents

Sources and Availability of Raw Materials and Principal Suppliers

We depend on a limited number of suppliers for certain raw materials, components, and equipment. Supplier relationships are reviewed to mitigate risks and lower costs, especially where we depend on a few suppliers for critical components or raw materials. Communications with suppliers are ongoing to prevent interruptions and our supply chain management is focused on maintaining quality while lowering purchase prices through standardized purchasing efficiencies and design requirements. We strive to limit inventories to levels sufficient to meet near-term needs.

Dependence on Major Customers

Our major customers include Lockheed Martin, who represented greater than 10% of consolidated revenue in the fiscal year ended September 30, 2024. See Note 14 – Revenue Information in the Notes to Consolidated Financial Statements for additional information about significant customers.

Patents and Trademarks

As of September 30, 2024, we held approximately 38 U.S. patents and approximately 34 foreign patents and approximately 34 additional patent applications are pending. The issued patents cover various products in the major markets we serve. Our U.S. patents will expire on varying dates between 2025 and 2040. These patents and patent applications claim protection for various aspects of current or planned commercial versions of our materials, components, subsystems, and systems. We also register our trademarks in the United States and other key international markets where we do business.

Effect of Governmental Regulations on the Business

We operate globally and are subject to numerous U.S. federal, state, and foreign laws and regulations covering a wide variety of subject matters. These laws and regulations are subject to change, and any such change may require us to improve our technologies, incur expenditures, or both, in order to comply with such laws and regulations. We are subject to rules promulgated by the SEC pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act regarding the use of “conflict minerals”. These rules have imposed and will continue to impose additional costs and may introduce new risks related to the ability to verify the origin of any “conflict minerals” used in our products. For information about governmental regulations applicable to our business, refer to Item 1A, “Risk Factors” included elsewhere in this Annual Report.

Costs and Effects of Compliance with Environmental Laws (Federal, State, and Local)

We are subject to U.S. federal, state, and local laws and regulations concerning the use, storage, handling, generation, treatment, emission, release, discharge, and disposal of certain materials used in research and development and production operations, as well as laws and regulations concerning environmental remediation, homeland security, and employee health and safety. The production of wafers and devices involves the use of certain hazardous raw materials, including, but not limited to, ammonia, phosphine, and arsine. We have in-house professionals to address compliance with applicable environmental, homeland security, and health and safety laws and regulations. We believe that we are currently in material compliance with all applicable federal, state, and local environmental protection laws and regulations.

Human Capital Resources

Our ability to attract and retain qualified personnel is essential to continued success. Competition is intense in recruiting personnel within the high tech and aerospace and defense industries. We are focused on retaining key contributors, developing staff, and cultivating their continued commitment. As of September 30, 2024, we had approximately 191 employees, of which approximately 188 are full-time employees.

ITEM 1A. Risk Factors.

You should carefully consider the risks described below, some of which have manifested and any of which may occur in the future, in addition to the other information contained in this report before making an investment decision with respect to any of our securities. Our business, results of operations, and financial condition could be materially and adversely impacted by any of these risks, which could in turn adversely affect our stock price. Additional risks not currently known to us or other factors not perceived by us as material risks could also present significant risks to our business.

Risks Related to Demand, Competition, Product Development and Manufacture, and Operations

We have incurred losses from continuing operations and our future profitability is not certain.

For the fiscal years ended September 30, 2024 and 2023, we incurred a loss from continuing operations of $26.9 million and $49.4 million, respectively. Our operating results for future periods are subject to numerous uncertainties and we cannot be certain that we will be profitable or that we will not experience substantial losses in the future. If we are not able to increase revenue and reduce our costs, we may not be able to achieve profitability in future periods and our business, financial condition, results of operations and cash flows may be adversely affected.

While the Company’s consolidated financial statements have been prepared on a going concern basis, we do not currently have sufficient working capital to fund our planned operations for the next twelve months and substantial doubt exists as to our ability to continue as a going concern.

The consolidated financial statements included herein have been prepared in accordance with GAAP assuming we will continue as a going concern. The going concern assumption contemplates the realization of assets and satisfaction of liabilities in the normal course of business. However, substantial doubt about our ability to continue as a going concern exists.

We have recently experienced significant losses from our operations and used a significant amount of cash, amounting to a net loss of $31.2 million and net cash outflows from continuing operations of $5.5 million for the fiscal year ended September 30, 2024, and we expect to continue to use cash in our operations. As a result of our recent cash outflows, we have taken actions to manage our liquidity and will need to continue to manage our liquidity as we continue to restructure our operations. As of September 30, 2024, our cash, cash equivalents and restricted cash totaled $10.8 million.

We are evaluating the sufficiency of our existing balances of cash and cash equivalents, cash flows from operations, and additional actions we could take to further reduce our expenses and/or potentially raising capital through additional debt or equity issuances, or from the potential monetization of certain assets. However, we may not be successful in executing on our plans to manage our liquidity, including recognizing the expected benefits from our previously executed restructuring program, or raising additional funds if we elect to do so, and as a result substantial doubt about our ability to continue as a going concern exists.

The consolidated financial statements included herein do not include any adjustments relating to the recoverability and classification of asset amounts or the classification of liabilities that might be necessary should the Company be unable to continue as a going concern.

We may not be able to obtain capital when desired on favorable terms, if at all, or without dilution to shareholders.

We operate in industries that make our prospects difficult to evaluate and predict. It is possible that we may not generate sufficient cash flow from operations or otherwise have the capital resources to meet our future capital needs. If this occurs, we may need additional financing to continue operations or to execute on our current or future business strategies, including to:

•invest in research and development efforts, including by hiring additional technical and other personnel;

•maintain and expand operating or manufacturing infrastructure;

•acquire complementary businesses, products, services or technologies; or

•otherwise pursue strategic plans and respond to competitive pressures.

If we raise additional funds through the issuance of equity or convertible debt securities, the percentage ownership of our shareholders could be significantly diluted, and these newly-issued securities may have rights, preferences, or privileges senior to those of existing shareholders. We cannot be certain that additional financing will be available on terms favorable to us, or at all. If adequate funds are not available or are not available on acceptable terms, if and when needed, our ability to fund our operations, take advantage of unanticipated opportunities, develop or enhance our products, or otherwise respond to competitive

Table of Contents

pressures could be significantly limited. Furthermore, in the event adequate capital is not available to us as required, or is not available on favorable terms, we may be required to adopt one or more alternatives including, but not limited to, selling additional assets, exiting additional business lines, further reductions of our capital expenditures, and delaying, reducing the scope of or eliminating one or more research and development programs or selling and marketing initiatives. If we are unable to manage discretionary spending, raise additional capital, or implement any of the above activities, as needed, we may need to further curtail planned activities to reduce costs, which could include additional reductions in workforce, additional eliminations of business activities and services, and further reductions in other operating expenses. Doing so could potentially have a material and adverse effect on our business, financial condition, results of operations, cash flows, and future prospects.

We may be unable to realize the level of the anticipated benefits that we expect from exiting businesses and restructuring our operations, which may adversely impact our business and results of operations.

From time to time, we may decide to exit certain businesses or otherwise undertake restructuring, reorganization, or other strategic initiatives to realign our resources with our growth strategies, operate more efficiently, and reduce costs. For example: in May 2024, we initiated a restructuring program that included the full closure of our Alhambra, CA facility, headcount reductions and additional reductions in operating expenses (the “May 2024 Restructuring”); in April 2023, we announced the shutdown of our Broadband business segment and our defense optoelectronics product line; in October 2023, we entered into an Asset Purchase Agreement with Photonics Foundries, Inc., a Delaware corporation (“PF”) and Ortel LLC, a Delaware limited liability company and wholly-owned subsidiary of PF (the “Buyer”) and consummated a transaction pursuant to which (i) we agreed to transfer to the Buyer, and Buyer agreed to assume, substantially all of the assets and liabilities primarily related to our TV, wireless, sensing and defense optoelectronics business lines (the “Businesses”), including with respect to employees, contracts, intellectual property and inventory, and (ii) Buyer agreed to provide a limited license back to us of the patents being sold to the Buyer (the “PF Transaction”); and in April 2024, we entered into an Asset Purchase Agreement, with HieFo Corporation, a Delaware corporation (“HieFo”), pursuant to which we transferred to HieFo substantially all of the assets primarily related to our discontinued chips business line, including with respect to equipment, contracts, intellectual property and inventory, including without limitation our indium phosphide wafer fabrication equipment (the “Chips Transaction”).

The successful implementation of our restructuring activities may from time to time require us to effect business and asset dispositions, workforce reductions, facility consolidations and closures, restructurings, management changes, reductions in investments, shut-downs or discontinuance of businesses, and other actions, each of which may depend on a number of factors that may not be within our control.

Any such effort to restructure or streamline our organization may result in restructuring or other costs, such as severance and termination costs, contract and lease termination costs, asset impairment charges, and other costs. Also, with respect to Buyer’s assumption of our manufacturing agreement with our electronics manufacturing services (“EMS”) provider for our cable TV products as part of the PF Transaction, we provided a guaranty of Buyer’s obligations with respect to payment of certain long-term liabilities that were originally agreed to and set forth in the manufacturing agreement and assigned to Buyer in the PF Transaction, in an aggregate amount expected to equal up to approximately $5.5 million, approximately $4.2 million of which will not become payable until January 2026, provided that if such guaranty is exercised by the EMS provider, we will have the right to require Buyer to reassign to us all intellectual property assigned to Buyer in the PF Transaction and we will have the right to recover damages from Buyer.

Further, as a result of restructuring initiatives, we may experience a loss of continuity, loss of accumulated knowledge and proficiency, adverse effects on employee morale, loss of key employees and other retention issues. Reorganization and restructuring can impact a significant amount of management and other employees’ time and resources, which may divert attention from operating and growing our business. Further, upon completion of any restructuring initiatives, our business may not be more efficient or effective than prior to the implementation of the plan and we may be unable to achieve anticipated benefits, including cost savings, which would adversely affect our business, competitive position, operating results, and financial condition.

We are a small company and dependent on a few products for success.

We are a small company with a narrow, focused portfolio of products. Our small size could cause our cash flow, results of operations, and growth prospects to be more volatile and makes us more vulnerable to focused competition. As a small company, we will be subject to greater revenue fluctuations if our older product lines’ sales were to decline faster than we anticipate. In addition, we may not be able to appropriately restructure or maintain our supporting functions to fit the needs of a small company, which could adversely affect our business, financial condition, results of operations, and cash flows.

Table of Contents

We are substantially dependent on revenues from a small number of customers. The loss of or decrease in sales from any one of these customers could adversely affect our business, financial condition, results of operations, and cash flows.

A small number of customers account for a significant portion of our revenue, and dependence on orders from a relatively small number of customers makes our relationship with each customer critically important to our business. For example, for the fiscal years ended September 30, 2024 and 2023, sales to one and two customers accounted for an aggregate of 21.1% and 40.4% of total consolidated revenues, respectively. Revenue from any major customer may decline or fluctuate significantly in the future. We may not be able to offset any decline in sales from existing major customers with sales from new customers or other existing customers. Because of reliance on a limited number of customers, any decrease in sales from, or loss of, one or more of these customers without a corresponding increase in sales from other customers would harm our business, operating results, financial condition, and cash flows.

In addition, any negative developments in the business of existing significant customers could result in significantly decreased sales to these customers, which could seriously harm our business, operating results, financial condition, and cash flows. If there is consolidation among our customer base, customers may be able to command increased leverage in negotiating prices and other terms of sale, which could adversely affect profitability. If we are required to reduce pricing, revenue and gross margins would be adversely impacted. Consolidation among our customer base may also lead to reduced demand for our products, replacement of our products by the combined entity with those of competitors, and cancellations of orders, each of which could adversely affect our business, financial condition, results of operations, and cash flows.

Although we are attempting to expand our customer base, the markets in which we sell our products are dominated by a relatively small number of companies, thereby limiting the number of potential customers. Accordingly, success will depend on our continued ability to develop and manage relationships with significant customers, and we expect that the majority of sales will continue to depend on sales of our products to a limited number of customers for the foreseeable future.

Future revenues are inherently unpredictable. As a result, operating results are likely to fluctuate from period to period, and we may fail to meet the expectations of analysts and/or investors, which may cause volatility in our stock price and may cause the stock price to decline.

Our quarterly and annual operating results have fluctuated substantially in the past and are likely to fluctuate significantly in the future due to a variety of factors, some of which are outside of our control. Factors that could cause quarterly or annual operating results to fluctuate include:

•increases or decreases in the markets for customers’ products;

•discontinuation by vendors of, or unavailability of, components or services used in our products;

•disruptions or delays in our manufacturing processes or in our supply of raw materials or product components;

•a failure to anticipate changing customer product requirements;

•market acceptance of our products;

•cancellations or postponements of previously placed orders;

•increased financing costs or any inability to obtain necessary financing;

•the impact on our business of current or future cost reduction measures;

•a loss of key personnel or the shortage of available skilled workers;

•economic conditions in various geographic areas where we or our customers do business;

•the impact of political uncertainties, such as government sequestration and uncertainties surrounding the federal budget, customer spending, and demand for our products;

•significant warranty claims, including those not covered by suppliers;

•product liability claims;

•other conditions affecting the timing of customer orders;

•reductions in prices for our products or increases in the costs of raw materials;

•effects of competitive pricing pressures, including decreases in average selling prices of our products;

•fluctuations in manufacturing yields;

•obsolescence of products;

•research and development expenses incurred associated with new product introductions;

•natural disasters, such as hurricanes, earthquakes, fires, and floods;

•pandemics;

•the emergence of new industry standards;

•the loss or gain of significant customers;

•the introduction of new products and manufacturing processes;

Table of Contents

•changes in technology;

•intellectual property disputes;

•customs (including tariffs imposed on our products or raw materials, equipment, or components used in the production of our products), import/export, and other regulations of the countries in which we do business;

•the occurrence of merger and acquisition activities; and

•acts of war, terrorism, or violence and international conflicts or crises.

As a result of the foregoing factors, we believe that period-to-period comparisons of results of operations should not be solely relied upon as indicators of future performance.

The acquisitions of EMCORE Chicago and S&N, and any potential future acquisitions of other companies or investments in joint ventures with other companies, could adversely affect operating results, dilute shareholders’ equity, or cause us to incur additional debt or assume contingent liabilities.

To increase business, maintain competitive position, or for other business or strategic reasons, we may acquire other companies or engage in joint ventures or similar transactions in the future. For example, in August 2022, we acquired EMCORE Chicago from KVH Industries, Inc. and in April 2022, we acquired S&N from L3Harris. The acquisitions of EMCORE Chicago and S&N, and any other acquisitions, joint ventures, and similar transactions that we may enter into from time to time, involve a number of risks that could harm our business and result in EMCORE Chicago, S&N, and/or any other acquired business or joint venture not performing as expected, including:

•problems integrating the acquired operations, personnel, technologies, or products with the existing business and products;

•failure to achieve cost savings or other financial or operating objectives with respect to an acquisition;

•possible adverse short-term effects on cash flows or operating results, and the use of cash and other resources for the acquisition that might affect liquidity, and that could have been used for other purposes;

•diversion of management’s time and attention from our existing business to the acquired business or joint venture;

•potential failure to retain key technical, management, sales, and other personnel of the acquired business or joint venture;

•difficulties in retaining relationships with suppliers and customers of the acquired business, particularly where such customers or suppliers compete with us;

•difficulties in the integration of financial reporting systems, which could cause a delay in the issuance of, or impact the reliability of the consolidated financial statements;

•failure to comply with Section 404 of the Sarbanes-Oxley Act of 2002, including a delay in or failure to successfully integrate these businesses into our internal control over financial reporting;

•insufficient experience with technologies and markets in which the acquired business is involved, which may be necessary to successfully operate and integrate the business;

•reliance upon joint ventures which we do not control;

•subsequent impairment of goodwill and acquired long-lived assets, including intangible assets; and

•assumption of liabilities including, but not limited to, lawsuits, environmental liabilities, regulatory liabilities, tax examinations, and warranty issues.

We may decide that it is in our best interests to enter into acquisitions, joint ventures, or similar transactions that are dilutive to earnings per share or that adversely impact margins as a whole. In addition, acquisitions or joint ventures could require investment of significant financial resources and require us to obtain additional equity financing, which may dilute shareholders’ equity, or require us to incur indebtedness.

Our ability to engage in any such activity is limited by, and will be subject to continued compliance with, the terms of and our obligations under the Merger Agreement (as defined below). For example, see “Risks Related to the Proposed Transaction—The Merger Agreement contains provisions that limit our ability to pursue an alternative transaction, which may discourage a potential third party from making a more favorable alternative transaction proposal, as well as certain limited termination provisions.”

We may consider from time to time further strategic opportunities that may involve acquisitions, dispositions, investments in joint ventures, partnerships, and other strategic alternatives that may enhance shareholder value, any of which may result in the use of a significant amount of management resources or significant costs, and we may not be able to fully realize the potential benefit of such transactions.

Table of Contents

We may consider acquisitions, dispositions, investments in joint ventures, partnerships, and other strategic alternatives that may enhance shareholder value, subject to compliance with the terms of, and our obligations under, the Merger Agreement. The Strategy and Alternatives Committee of the Board of Directors and management may from time to time be engaged in evaluating potential transactions and other strategic alternatives. In addition, from time to time, we may engage financial advisors, enter into non-disclosure agreements, conduct discussions, and undertake other actions that may result in one or more transactions.

Although there would be uncertainty that any of these activities or discussions would result in definitive agreements or the completion of any transaction, we may devote a significant amount of management resources to analyzing and pursuing such a transaction, which could negatively impact operations. In addition, we may incur significant costs in connection with seeking such transactions or other strategic alternatives regardless of whether the transaction is completed. In the event that we consummate an acquisition, disposition, partnership, or other strategic alternative in the future, we cannot be certain that we would fully realize the anticipated benefits of such a transaction and cannot predict the impact that such strategic transaction might have on our operations or stock price.

The market price for our common stock has experienced significant price and volume volatility and is likely to continue to experience significant volatility in the future. This volatility may impair the ability to finance strategic transactions with our stock and otherwise harm our business.

Our stock price has experienced significant price and volume volatility for the past several years, and our stock price is likely to experience significant volatility in the future. The trading price of our common stock may be influenced by factors beyond our control, such as the volatility of the financial markets, uncertainty surrounding domestic and foreign economies, conditions and trends in the markets we serve, changes in the estimation of the future size and growth rate of our markets, publication of research reports, and recommendations by financial analysts relating to our business, the business of competitors, or the industries in which we operate and compete, changes in market valuation or earnings of competitors, legislation or regulatory policies, practices, or actions, sales of our common stock by principal shareholders, and the trading volume of our common stock. The historical market prices of our common stock may not be indicative of future market prices and we may be unable to sustain or increase the value of our common stock. We have historically used equity incentive compensation as part of our overall compensation arrangements. The effectiveness of equity incentive compensation in retaining key employees may be adversely impacted by volatility in our stock price. Significant declines in our stock price may also interfere with the ability, if needed, to raise additional funds through equity financing or to finance strategic transactions with our stock. In addition, there may be increased risk of securities litigation following periods of fluctuations in our stock price. Securities class action lawsuits are often brought against companies after periods of volatility in the market price of their securities. These and other consequences of volatility in our stock price which could be exacerbated by macroeconomic conditions that affect the market generally, or our industries in particular, could have the effect of diverting management’s attention and could materially harm our business.

Our operating results could be harmed if we are unable to obtain timely deliveries of sufficient materials, components, or services of acceptable quality from sole or limited sources, or if the prices of materials, components, or services for which we do not have alternative sources increase.

We currently obtain materials, components, and services used in our products from limited or sole sources. We generally do not carry significant inventories of any raw materials. The reliance on a sole supplier, single qualified vendor, or limited number of suppliers could result in delivery or quality problems or reduced control over product pricing, reliability, and performance. For example, during the fiscal year ended September 30, 2022, COVID-19 driven component shortages and delays required us to source critical components from alternative sources and, in some cases, to design in alternative parts and qualify them with customers on short schedules. Because we often do not account for a significant part of our suppliers’ businesses, we may not have access to sufficient capacity from these suppliers in periods of high demand. In addition, since we generally do not have guaranteed supply arrangements with suppliers, we risk serious disruption to operations if an important supplier terminates product lines, changes business focus, or goes out of business, and we may need large end-of-life purchases when a sole source supplier is ceasing manufacturing of required components. Because some of these suppliers are located overseas, we may be faced with higher costs of purchasing these materials if the U.S. dollar weakens against other currencies, or if import tariffs are

Table of Contents

imposed on these materials. If we were to change any of our limited or sole source suppliers, we would be required to re-qualify each new supplier. Re-qualification could prevent or delay product shipments that could adversely affect results of operations and cash flows. In addition, reliance on these suppliers may adversely affect production if the components vary in quality or quantity. If we are unable to obtain timely deliveries of sufficient components of acceptable quality or if the prices of components for which we do not have alternative sources increase, our business, financial condition, results of operations, and cash flows could be materially adversely affected.

Our products are complex and may take longer to develop and qualify than anticipated and we face lengthy sales and qualification cycles for our new products and, in many cases, must invest a substantial amount of time and money before we receive orders.

We develop new products and use new technologies in these products. These products often take substantial time to develop because of the complexity, rigorous testing, and qualification requirements and because customer and market requirements can change during the product development or qualification process. Some of our products are tested by current and potential customers as part of the development and qualification process to determine whether they meet customer or industry specifications. The length of the qualification process, which can span a year or more, varies substantially by product and customer and, thus, can cause results of operations and cash flows to be unpredictable. During a given qualification period, we invest significant resources and allocate substantial production capacity to manufacture these new products prior to any commitment to purchase by customers. In addition, it is difficult to obtain new customers during the qualification period as customers are reluctant to expend the resources necessary to qualify a new supplier if they have one or more existing qualified sources. If we are unable to meet applicable specifications or do not receive sufficient orders to profitably use allocated production capacity, our business, financial condition, results of operations, and cash flows may be adversely affected.

Historical and future budgets for operating expenses, capital expenditures, operating leases, and service contracts are based upon assumptions as to the future market acceptance of our products. Because of the lengthy lead times required for product development and the changes in technology that typically occur while a product is being developed, it is difficult to accurately estimate customer demand for any given product. If our products do not achieve an adequate level of customer demand, our business, financial condition, results of operations, and cash flows may be adversely affected.

Our products are difficult to manufacture. Production could be disrupted and results of operations and cash flows could suffer if production yields are low as a result of manufacturing difficulties.

We manufacture our products in our own production facilities. Difficulties in the production process, such as contamination, raw material quality issues, human error, or equipment failure, could cause a substantial percentage of products to be nonfunctional. These problems may be difficult to detect at an early stage of the manufacturing process and are often time-consuming and expensive to correct. Lower-than-expected production yields may delay shipments or result in unexpected levels of warranty claims, either of which could adversely affect results of operations and cash flows. We have experienced difficulties in achieving planned yields in the past, particularly in pre-production and upon initial commencement of full production volumes, which have adversely affected gross margins. Because the majority of our manufacturing costs are fixed, achieving planned production yields is critical to results of operations and cash flows. Changes in manufacturing processes required as a result of changes in product specifications, changing customer needs, and the introduction of new product lines could significantly reduce manufacturing yields, resulting in low or negative margins on those products. In addition, transitioning to automation in certain manufacturing processes could result in manufacturing delays or significantly reduce manufacturing yields.

Manufacturing yields depend on a number of factors, including the stability and manufacturability of the product design, manufacturing improvements gained over cumulative production volumes, the quality and consistency of component parts, and the nature and extent of customization requirements by customers. Higher volume demand for more mature designs requiring less customization generally results in higher manufacturing yields than products with lower volumes, less mature designs, and requiring extensive customization. Capacity constraints, raw materials shortages, logistics issues, the introduction of new product lines and changes in customer requirements, manufacturing facilities, or processes or those of third-party component suppliers have historically caused, and may in the future cause, significantly reduced manufacturing yields, negatively impacting the gross margins on, and production capacity for, those products. Our ability to maintain sufficient manufacturing yields is particularly important with respect to certain products we manufacture, as a result of the long manufacturing process. Moreover, an increase in the rejection and rework rate of products during the quality control process before, during, or after manufacture would result in lower yields, gross margins, and production capacity. Finally, manufacturing yields and margins can also be lower if we receive and inadvertently use defective or contaminated materials from suppliers.

Table of Contents

We also have substantial risk of interruption in manufacturing resulting from fire, natural disaster, equipment failures, acts of government, or similar events, because we manufacture most of our products using few facilities, and do not have back-up facilities available for manufacturing these products. We could also incur significant costs to repair or replace products that are defective and, in some cases, costly product redesigns and/or rework may be required to correct a defect. Additionally, any defect could adversely affect our reputation and result in the loss of future orders.

Some of the capital equipment used in the manufacture of our products have been developed and made specifically for us, may not be readily available from multiple vendors, and would be difficult to repair or replace if they were to become damaged or stop working. If any of these suppliers were to experience financial difficulties or go out of business, or if there were any damage to, or a breakdown of manufacturing equipment at a time when we are manufacturing commercial quantities of our products, our business, financial condition, results of operations, and cash flows could be adversely affected.

If we do not keep pace with rapid technological change, our products may not be competitive.

We compete in markets that are characterized by rapid technological change, frequent new product introductions, changes in customer requirements, evolving industry standards, continuous improvement in products, and the use of our existing products in new applications. We may not be able to develop the underlying core technologies necessary to create new products and enhancements to our existing products at the same rate as or faster than competitors, to develop products that effectively compete with competitors’ products used in new applications or to license the technology from third parties that is necessary for our products. Product development delays may result from numerous factors, including:

•changing product specifications and customer requirements;

•unanticipated engineering complexities;

•expense reduction measures we have implemented and others we may implement;

•difficulties in hiring and retaining necessary technical personnel; and

•difficulties in allocating engineering resources and overcoming resource limitations.

We cannot be certain that we will be able to identify, develop, manufacture, market, or support new or enhanced products successfully, if at all, or on a timely, cost effective, or repeatable basis. Future performance will depend on successful development and introduction of, as well as market acceptance of, new and enhanced products that address market changes, as well as current and potential customer requirements and ability to respond effectively to product announcements by competitors, technological changes, or emerging industry standards. Because it is generally not possible to predict the amount of time required and the costs involved in achieving certain research, development, and engineering objectives, actual development costs may exceed budgeted amounts and estimated product development schedules may be extended. If we are unable to develop, manufacture, market, or support new or enhanced products successfully, or incur budget overruns or delays in research and development efforts, our business, financial condition, results of operations, and cash flows may be adversely affected.

Increased spending to develop and improve technology may adversely impact financial results.

We may increase research and development and/or capital expenditures and expenses in order to attempt to improve existing technology and develop new technology. Increasing investments in research and development of technology could cause our cost structure to fall out of alignment with demand for our products, which would have a negative impact on financial results. If we are unable to fund these types of expenditures, we may be unable to improve technology or develop new technologies, which may adversely affect our business, financial condition, results of operations, and cash flows. Further, our research and development programs may not produce successful results, and our new products and services may not achieve market acceptance, create additional revenue, or become profitable, which could materially harm our business, prospects, financial results, and liquidity.

The competitive and rapidly evolving nature of our industries and pressure from competitors with greater resources has in the past resulted in, and is likely in the future to result in, reductions in our product prices and periods of reduced demand for our products.

We face substantial competition from a number of companies, many of which have greater financial, marketing, manufacturing, and technical resources than we do. Larger-sized competitors often spend more on research and development, which could give those competitors an advantage in meeting customer demands and introducing technologically innovative products before we do. We expect that existing and new competitors will continue to improve the design of their existing products and will introduce new products with enhanced performance characteristics.

Table of Contents

The introduction of new products and more efficient production of existing products by competitors have resulted in, and are likely in the future to result in, price reductions, increases in expenses, and reduced demand for our products. In addition, competitors may be willing to provide their products at lower prices, accept a lower profit margin, or spend more capital in order to obtain or retain business. These competitive forces could diminish our market share and gross margins, resulting in an adverse effect on our business, financial condition, results of operations, and cash flows.

New competitors may also enter our markets, including some current and potential customers who may attempt to integrate their operations by producing their own components or acquiring a competitor, thereby reducing demand for our products. In addition, rapid product development cycles, increasing price competition due to maturation of technologies, the emergence of new competitors with lower cost structures, and industry consolidation resulting in competitors with greater financial, marketing, and technical resources could result in lower prices or reduced demand for our products, which could have an adverse effect on our business, financial condition, results of operations, and cash flows.

Expected and actual introductions of new and enhanced products may cause customers to defer or cancel orders for existing products and may cause our products to become obsolete. A slowdown in demand for existing products ahead of a new product introduction could result in a write-down in the value of inventory on hand related to existing products. We have in the past experienced a slowdown in demand for existing products and delays in new product development and such delays may occur in the future. To the extent customers defer or cancel orders for existing products due to a slowdown in demand or in anticipation of a new product release, or if there is any delay in development or introduction of our new products or enhancements of our products, our business, financial condition, results of operations, and cash flows could be adversely affected.

Customer demand is difficult to forecast and, as a result, we may be unable to optimally match production with customer demand.

We make planning and spending decisions, including determining the levels of business that we will seek and accept, production schedules, component procurement commitments, personnel needs and other resource requirements, based on estimates of customer demand. While customers generally provide us with their demand forecasts, they are typically not contractually committed to buy any quantity of products beyond firm purchase orders. The short-term nature of customer commitments and the possibility of unexpected changes in demand for their products limit the ability to accurately predict future customer demand. On occasion, customers have required rapid increases in production, which has strained resources. We may not have sufficient capacity at any given time to meet the volume demands of customers, or one or more suppliers may not have sufficient capacity at any given time to meet our volume demands. Conversely, a downturn in the markets in which our customers compete can cause, and in the past has caused, customers to significantly reduce the amount of products ordered from us or to cancel existing orders, leading to lower utilization of our facilities. Because many of our costs and operating expenses are relatively fixed, reduction in customer demand would have an adverse effect on gross margin, results of operations, and cash flow. During an industry downturn, there is also a higher risk that a larger portion of trade receivables would be uncollectible. In addition, certain arrangements with component vendors require us to purchase minimum quantities of components within specific time periods, which could cause us to hold excess inventories of these components during periods concurrent with a decrease in customer demand for our products.

A failure to attract and retain managerial, technical, and other key personnel could reduce revenue and operational effectiveness.

Future success depends, in part, on the ability to attract and retain certain key personnel, including scientific, operational, financial, and managerial personnel. In addition, technical personnel represent a significant asset and serve as the source of our technological and product innovations. The competition for attracting and retaining key employees (especially scientists, technical personnel, senior managers, and executives) is intense. Because of this competition for skilled employees, we may be unable to retain existing personnel or attract additional qualified employees in the future to keep up with business demands and changes, and our business, financial condition, results of operations, and cash flows could be adversely affected. The risks involved in recruiting and retaining these key personnel may be increased by our historical lack of profitability, the volatility of our stock price, and the perceived effect of previously implemented reductions in workforce and other cost reduction efforts.

Our ability to achieve operational and material cost reductions and to realize production efficiencies for operations is critical to long-term profitability.

We have implemented a number of operational and material cost reductions and productivity improvement initiatives, which are intended to reduce our cost structure at both the cost of revenue and the operating expense levels. Cost reduction initiatives

Table of Contents

often involve the re-design of our products, which requires customers to accept and qualify the new designs, potentially creating a competitive disadvantage for our products. These initiatives can be time-consuming, disruptive to operations, and costly in the short-term. Successfully implementing these and other cost-reduction initiatives throughout operations is critical to future competitiveness and ability to achieve long-term profitability. However, we cannot be certain that these initiatives will be successful in creating profit margins sufficient to sustain our current operating structure and business.

Our products may contain defects that could cause us to incur significant costs, divert management’s attention, result in a loss of customers, and result in product liability claims.

Our products are complex and undergo quality testing and formal qualification by customers and us. However, defects may occur from time to time. Customer testing procedures involve evaluating our products under likely and foreseeable failure scenarios and over varying amounts of time. For various reasons, such as the occurrence of performance problems that are unforeseeable in testing or that are detected only when products age or are operated under peak stress conditions, our products may fail to perform as expected long after customer acceptance. Failures could result from faulty components or design, problems in manufacturing, or other unforeseen reasons. For the majority of our products, we provide a product warranty of one year or less from the date of shipment. As a result, we could incur significant costs to repair or replace defective products under warranty, particularly when such failures occur in installed systems. We have experienced failures in the past and will continue to face this risk going forward, as our products are widely deployed throughout the world in multiple demanding environments and applications. In addition, we may in certain circumstances, honor warranty claims after the warranty has expired or for problems not covered by warranty in order to maintain customer relationships. Any significant product failure could result in product recalls, product liability claims, lost future sales of the affected product, and other products, as well as customer relations problems, litigation, and damage to our reputation.

In addition, our products are typically embedded in, or deployed in conjunction with, customers’ products, which incorporate a variety of components, modules, and subsystems and may be expected to interoperate with modules and subsystems produced by third parties. As a result, not all defects are immediately detectable and when problems occur, it may be difficult to identify the source of the problem. These problems may cause us to incur significant damages or warranty and repair costs, divert the attention of engineering personnel from product development efforts, and cause significant customer relations problems or loss of customers, all of which would harm our business. The occurrence of any defects in products could also give rise to liability for damages caused by such defects. Although we carry product liability insurance to mitigate this risk, insurance may not adequately or entirely cover costs that may arise from defects in products or otherwise, nor will it protect us from reputational harm that may result from such defects. Costs incurred in connection with product recalls or warranty or product liability claims may adversely affect our business, financial condition, results of operations, and cash flows.

Shifts in industry-wide demands and inventories could result in significant inventory write-downs.

The life cycles of some products depend heavily upon the life cycles of the end products into which our products are designed. Products with short life cycles require us to manage production and inventory levels closely. We evaluate ending inventories on a quarterly basis for excess quantities, impairment of value, and obsolescence. This evaluation includes analysis of sales levels by product and projections of future demand based upon input received from customers, sales team, and management. If inventories on hand are in excess of demand, or if they are generally greater than 12 months old, appropriate write-downs may be recorded. In addition, we write-off inventories that are considered obsolete based upon changes in customer demand, manufacturing process changes that result in existing inventory obsolescence, or new product introductions which eliminate demand for existing products. Remaining inventory balances are adjusted to approximate the lower of manufacturing cost or net realizable market value.

If future demand or market conditions are less favorable than estimates, inventory write-downs may be required. We cannot be certain that obsolete or excess inventories, which may result from unanticipated changes in the estimated total demand for our products and/or the estimated life cycles of the end products into which our products are designed, will not affect us beyond the inventory charges that we have already taken.

The types of sales contracts we use in the markets we serve subject us to unique risks in each of those markets.

For most of our products, we do not have long-term supply contracts with customers and typically sell our products pursuant to purchase orders with short lead times, and even where we do have long-term supply contracts, customers are typically not obligated to purchase any minimum amount of our products. As a result, in most cases customers could stop purchasing our products at any time, and we must fulfill orders in a timely manner to keep them satisfied.

Table of Contents

Risks associated with an absence of long-term purchase commitments with customers include the following:

•customers can stop purchasing our products at any time without penalty;

•customers may purchase products from competitors; and

•customers are not required to make minimum purchases.

These risks are increased by the fact that our customers include large, sophisticated companies that have considerable purchasing power and control over their suppliers. If we are unable to fulfill these orders in a timely manner, it is likely that we will lose sales and customers.

The majority of our development contracts are for a fixed price, and fixed price development work inherently has more uncertainty than production contracts and, therefore, entails more variability in estimates of the cost to complete the work. Many of these development programs have very complex designs. As technical or quality issues arise, we may experience schedule delays and adverse cost impacts, which could increase estimated cost to perform the work, either of which could adversely affect results of operations. Some fixed price development contracts include initial production units in their scope of work. Successful performance of these contracts depends on the ability to meet production specifications and delivery rates. If we are unable to meet these contract requirements, revenue from these contracts could be reduced through the incorporation of liquidated damages, the contract could be terminated for default, and we could be subject to other financially significant consequences. We use our best judgment to estimate the cost to perform the work and the price we will eventually be paid on fixed price development programs. While we believe the cost and price estimates used to prepare the consolidated financial statements are appropriate, future events could result in unfavorable adjustments to those estimates which in turn would adversely affect results of operations.

We are subject to risks associated with the availability and coverage of insurance.

For certain risks, we do not maintain insurance coverage because of cost or availability. Because we retain some portion of our insurable risks, and in some cases self-insure completely, unforeseen or catastrophic losses in excess of insured limits may have an adverse effect on our business, financial condition, results of operations, and cash flows.

Risks Related to International Sales and Operations

We previously had operations in China with respect to our Broadband business, which exposes us to risks inherent in doing business in China.

We previously operated certain logistic functions with respect to our Broadband business in China, which operations were sold in connection with the Broadband transaction. Our previous China-based activities were subject to greater political, legal, and economic risks than those faced by our other operations. In particular, the political, legal, and economic climate in China (both at the national and regional levels) is extremely volatile and unpredictable. We may be adversely affected by any previous failure to comply with, Chinese laws and regulations, such as those relating to taxation, import and export tariffs, environmental regulations, land use rights, intellectual property, labor and employment laws, and other matters. Moreover, the enforceability of applicable existing Chinese laws and regulations is uncertain. For example, since Chinese administrative and court authorities have significant discretion in interpreting and implementing statutory and contract terms, it may be more difficult to evaluate the outcome of administrative and court proceedings and the level of legal protection we would receive. In addition, protections of intellectual property rights and confidentiality in China may not be as effective as in the U.S. or other countries or regions. All of these uncertainties could limit the legal protections available to us and could materially and adversely affect our business, financial condition, cash flows, and results of operations.

Also, if we are found to be, or to have been, in violation of Chinese laws or regulations governing technology import and export, the relevant regulatory authorities have broad discretion in dealing with such violations, including, but not limited to, issuing a warning, levying fines, restricting us from benefiting from these technologies inside or outside of China, confiscating our earnings generated from the import or export of such technology or even restricting our future import and export of any technology.

In the past, we were required to pay income taxes in China subject to certain tax relief. In the event that we become subject to any increased taxes or new forms of taxation imposed by authorities in China, results of operations and cash flows could be adversely affected.

We have significant international sales, which expose us to additional risks and uncertainties.

Table of Contents

For the fiscal years ended September 30, 2024 and 2023, sales to customers located outside the U.S. and Canada accounted for approximately 28% and 23%, respectively, of consolidated revenue, with revenue assigned to geographic regions based on customers’ billing address. Sales to customers in Asia and Europe represent the majority of international sales for the fiscal years ended September 30, 2024 and 2023, respectively. We believe that international sales will continue to account for a significant percentage of revenue as we seek international expansion opportunities. In addition, certain sales to customers with a U.S. billing address may be physically shipped to a location outside of the U.S. International sales and operations are subject to a number of material risks, including, but not limited to:

•political and economic instability or changes in U.S. government policy with respect to the foreign countries where customers are located may inhibit export of products and limit potential customers’ access to U.S. dollars in a country or region in which those potential customers are located;

•we may experience difficulties in enforcing legal contracts or the collection of foreign accounts receivable in a timely manner and we may be forced to write off these receivables;

•tariffs and other barriers may make our products less cost competitive or may reduce gross margin on these products;

•the laws of certain foreign countries may not adequately protect our trade secrets and intellectual property or may be burdensome to comply with;

•potentially adverse tax consequences to customers may damage cost competitiveness;

•customs, import/export, and other regulations of the countries in which we do business may adversely affect our business;

•different technical standards or requirements, such as country or region specific requirements to eliminate the use of lead, which we may incorporate into certain products, could prevent us from selling these products in these regions;

•currency fluctuations may make our products less cost competitive, affecting overseas demand for our products or otherwise adversely affecting our business; and

•language and other cultural barriers may require us to expend additional resources competing in foreign markets or hinder the ability to effectively compete.

Negative developments in one or more countries or regions in which we operate or sell our products could result in a reduction in demand for our products, the cancellation or delay of orders already placed, difficulties in producing and delivering our products, threats to our intellectual property, difficulty in collecting receivables, or a higher cost of doing business, any of which could negatively impact our business, financial condition, cash flows, and results of operations. In addition, we may be exposed to legal risks under the laws of the countries outside the U.S. in which we do business, as well as the laws of the U.S. governing our business activities in those other countries, such as the U.S. Foreign Corrupt Practices Act (“FCPA”).

Risks Related to the Proposed Transaction

The announcement and pendency of the Proposed Transaction could adversely impact our business, financial condition, and results of operations.

On November 7, 2024, we entered into an agreement and plan of merger (the “Merger Agreement”) with Velocity One Holdings, LP, a Delaware limited partnership (“Parent”), Aerosphere Power Inc., a New Jersey corporation that, at the effective time of the Merger (as defined below) will be an indirect wholly owned subsidiary of Parent (“Parent Group Member”), and Velocity Merger Sub, Inc., a New Jersey corporation that, at the effective time of the Merger will be an indirect wholly owned subsidiary of Parent (“Merger Sub”). Subject to the terms and conditions set forth in the Merger Agreement, Merger Sub will merge with and into the Company (the “Merger”), with the Company surviving the Merger and becoming an indirect wholly owned subsidiary of Parent (the “Proposed Transaction”). Uncertainty about the effect of the Proposed Transaction on our employees, customers, and other parties may have an adverse effect on our business, financial condition, and results of operations regardless of whether the Proposed Transaction is completed. These risks to our business in connection with the Proposed Transaction include the following, all of which could be exacerbated by a delay in the consummation of the Proposed Transaction:

•the diversion of significant management time and resources from our ongoing business and operations as a result of the devotion of management’s attention to the Proposed Transaction;

•the impairment of our ability to retain, hire, and motivate our employees, including key personnel;

•operating costs, customer loss, and business disruption (including, without limitation, difficulties in maintaining employee, customer, or other business, contractual, or operational relationships following the announcement of the Proposed Transaction);

•delays or deferrals of certain business decisions by our customers, suppliers, and other business partners;

•the inability to pursue alternative business opportunities or make appropriate changes to our business because, subject to certain exceptions, the Merger Agreement requires us to use commercially reasonable efforts to conduct our

Table of Contents

business and operations only in the ordinary course of business consistent with past practice and to maintain and preserve intact our business organization, assets, and properties; to keep available the services of our current officers, employees, and consultants; to preserve our goodwill and current relationships with customers, suppliers, distributors, licensors, licensees, and other persons with which we have business relations; and to not engage in certain material transactions prior to the earlier of the effective time of the Merger or the termination of the Merger Agreement;

•the occurrence of any event, change, or other circumstance that could give rise to the termination of the Merger Agreement, which in certain circumstances may require us to pay a termination fee;

•litigation matters relating to the Proposed Transaction, including the nature, costs, and outcome of any future litigation and other legal proceedings related to the Proposed Transaction;

•the incurrence of significant costs, fees, and expenses for professional services and other transaction costs in connection with the Proposed Transaction; and

•potential negative reactions from the financial markets.

In addition, subject to compliance with the terms of, and our obligations under, the Merger Agreement, any acquisition, merger, disposition, strategic investment, or similar activity may disrupt our ongoing operations, divert management from their primary responsibilities, subject us to additional liabilities, increase our expenses, and otherwise adversely impact our business, financial condition, and results of operations. We may not achieve any or all of the anticipated financial results, cost synergies, or other benefits expected in connection with any such transaction, or strengthen our competitive position, or achieve other anticipated goals in a timely manner, or at all. Further, such transactions may be viewed negatively by our current or potential customers, financial markets, or investors.

The completion of the Proposed Transaction is subject to the satisfaction or waiver of certain closing conditions by us, Parent, Parent Group Member, and Merger Sub, including shareholder approval and the absence of any laws or orders that would prohibit consummation of the Merger or the transactions contemplated by the Merger Agreement, and the failure to consummate the Proposed Transaction within the expected timeframe or at all could adversely impact our business, financial condition, and results of operations.

The obligations of each party to the Merger Agreement to effect the Merger are subject to the satisfaction or waiver of various and customary closing conditions, including (but not limited to): (i) the accuracy of the representations and warranties contained in the Merger Agreement, subject to certain customary materiality qualifications, as of the date of the Merger Agreement and as of the closing of the Proposed Transaction, and performance in all material respects of all obligations, and compliance in all material respects with the agreements and covenants, contained in the Merger Agreement; (ii) the adoption of the Merger Agreement by the affirmative vote of a majority of the votes cast by the holders of the outstanding shares of our common stock entitled to vote thereon (the “Shareholder Approval”); (iii) the absence of any laws or orders, writs, assessments, decisions, injunctions, decrees, rulings, or judgments that makes illegal, enjoins, or otherwise prohibits the consummation of the Merger or the other transactions contemplated by the Merger Agreement; and (iv) the absence of a Company Material Adverse Effect (as defined in the Merger Agreement) between the date of the Merger Agreement and the closing of the Merger.

We can provide no assurance that the closing conditions will be fulfilled (or waived, if applicable) in a timely manner or at all, and, if all closing conditions are timely fulfilled (or waived, if applicable), we can provide no assurance as to the terms, conditions, and timing of the completion of the Proposed Transaction. Many of the conditions to completion of the Proposed Transaction are not within our control, and we cannot predict when or if these conditions will be fulfilled (or waived, if applicable).

The Proposed Transaction is complex in nature, and unanticipated developments, including, among other things, changes in law, the macroeconomic environment, market conditions, regulatory or geopolitical conditions, or natural disasters, may affect our, Parent’s, Parent Group Member’s or Merger Sub’s ability to close the Proposed Transaction as currently expected and within the anticipated time frame or at all. Additionally, the Merger Agreement includes certain termination rights for each of us, Parent, and Merger Sub, subject, in certain circumstances, to our payment to Parent of a termination fee in an aggregate amount of $1.5 million in cash upon termination of the Merger Agreement under specified circumstances. If we are required to make this payment, doing so may materially adversely affect our business, financial condition, and results of operations.

Any changes to the Proposed Transaction or delay in closing the Proposed Transaction could cause us, Parent, Parent Group Member, or Merger Sub not to realize some or all of the expected benefits or to realize them on a different timeline than expected. In addition, the terms and conditions of the required regulatory authorizations and consents that are granted, if any, may impose requirements, limitations, or costs, or materially delay the closing of the Proposed Transaction. If the closing of the Proposed Transaction is delayed or does not occur, this could result in a material adverse effect on our financial condition, results of operations, ability to pursue alternative transactions, and reputation.

There can be no assurance that a remedy will be available to us in the event of a breach of the Merger Agreement by any other party to the Merger Agreement, or that we will wholly or partially recover for any damages incurred by us in connection with the Proposed Transaction. A failed transaction may result in negative publicity and a negative impression of us among our

Table of Contents

customers or in the investment community or business community generally. Further, any disruptions to our business resulting from the announcement and pendency of the Proposed Transaction, including any adverse changes in our relationships with our customers, suppliers, lenders, partners, officers, employees, governmental entities, and other third parties, could continue or accelerate in the event of a failed transaction or the perception that the Proposed Transaction may be delayed or may not close. In addition, if the Proposed Transaction is not consummated, the share price of our common stock may likely decline, including below the $3.10 per share price of the Proposed Transaction. Further, as our shareholders will receive cash in exchange for their shares (assuming the Proposed Transaction is consummated), our shareholders will not be able to share in any potential upside of our common stock after the closing.

We have incurred, and will continue to incur, significant costs, expenses, fees, and other transaction costs in connection with the Proposed Transaction, for which we will have received little or no benefit if the Proposed Transaction is not completed. Fees and costs will be payable by us even if the Proposed Transaction is not completed and may relate to activities that we would not have undertaken except in connection with the Proposed Transaction.

The Merger Agreement contains provisions that limit our ability to pursue an alternative transaction, which may discourage a potential third party from making a more favorable alternative transaction proposal, as well as certain limited termination provisions.

The Merger Agreement contains provisions that make it more difficult for us to seek an alternative transaction. Under these provisions, we have agreed, among other things, not to (a) directly or indirectly solicit, initiate, or knowingly take any action to facilitate or encourage the submission of any Takeover Proposal (as defined in the Merger Agreement), or the making of any proposal that would reasonably be expected to lead to a Takeover Proposal (as defined in the Merger Agreement); or (b) continue, conduct, or engage in any discussions or negotiations with, disclose any non-public information to, afford access to our business, properties, assets, books, or records to, or knowingly assist, participate in, facilitate, or encourage any effort by, any third party relating to a Takeover Proposal or any inquiry or proposal that would reasonably be expected to lead to a Takeover Proposal (collectively, the “No Shop Restriction”).

Notwithstanding the foregoing, prior to receipt of the Shareholder Approval, our Board of Directors may (a) participate in discussions with any third party that has made (and not withdrawn) a written Takeover Proposal that did not result from a material breach of the No Shop Restriction that our Board of Directors believes in good faith, after consultation with its financial advisor and outside legal counsel, is or would reasonably be expected to lead to a Superior Proposal (as defined in the Merger Agreement) or would reasonably be expected to be inconsistent with the fiduciary duties of our Board of Directors under applicable law not to participate in negotiations or discussions pertaining to such Takeover Proposal, and (b) then furnish certain information regarding us or our subsidiaries pursuant to an acceptable confidentiality agreement, in each case subject to complying with specified notice requirements and other conditions as set forth in the Merger Agreement.

These provisions could discourage a potential third-party acquirer or merger partner that might have an interest in acquiring or combining with all or a significant portion of our business or pursuing an alternative transaction with us from considering or proposing such a transaction.

Prior to obtaining the Shareholder Approval, our Board of Directors may, in certain limited circumstances, authorize us to enter into a definitive agreement to effect a Takeover Proposal in respect of a Superior Proposal (as defined in the Merger Agreement), and we may terminate the Merger Agreement. In this and other specified circumstances, we would be required to pay to Parent a termination fee in an aggregate amount of $1.5 million in cash upon termination of the Merger Agreement.

In addition, we may terminate the Merger Agreement under certain circumstances, including if the Proposed Transaction is not consummated on or before May 7, 2025. However, this termination right will not be available to us if the principal cause of the failure to consummate the Merger by such date is attributable to our breach of any representation, warranty, covenant, or agreement in the Merger Agreement. If we terminate the Merger Agreement, this could result in a material adverse impact on our results of operations, and if the Merger Agreement is terminated and we seek another business combination transaction, we may not be able to negotiate a transaction with another party on terms comparable to, or better than, the terms of the Proposed Transaction.

We will incur significant costs related to the Proposed Transaction that could have a material adverse effect on our liquidity, cash flows, and operating results.

We expect to incur significant costs in connection with the Proposed Transaction, including transaction costs, legal and regulatory fees, and other costs that our management team believes are necessary to effect or realize the anticipated benefits from the Proposed Transaction. The incurrence of these costs could have a material adverse effect on our financial condition and results of operations, including in the periods in which they are incurred.

Table of Contents

The Merger Agreement contains our specified termination rights, including, among other things, that prior to obtaining the Shareholder Approval, our Board of Directors may, in certain limited circumstances, authorize us to enter into a definitive agreement to effect a Takeover Proposal in respect of a Superior Proposal (as defined in the Merger Agreement), and we may terminate the Merger Agreement. In this and other specified circumstances, we would be required to pay to Parent a termination fee in an aggregate amount of $1.5 million in cash upon termination of the Merger Agreement. The incurrence of such fee may have a material adverse effect on our liquidity, cash flows, and operating results in the period in which it is incurred.

The consideration to be paid by Parent to our shareholders will not be adjusted in the event the value of our business or assets changes before the Proposed Transaction closes.

The consideration to be paid by Parent to our shareholders will not be adjusted in the event the value of our business or assets changes. If the value of our business or assets changes after our shareholders approve the adoption of the Merger Agreement, the trading price of shares of our common stock may be less than or greater than our shareholders had anticipated when they considered the adoption of the Merger Agreement. Pursuant to the Merger Agreement, we will not be permitted to terminate the Merger Agreement solely because of changes in the trading price of shares of our common stock.

The trading price of our shares of common stock may fluctuate as a result of the Proposed Transaction.

There can be no assurance that the trading price of our shares of common stock will not fluctuate prior to the closing of the Proposed Transaction. The trading price may increase or decrease (including above or below the $3.10 per share consideration to be paid by Parent) due to, among other things, uncertainty of the closing of the Proposed Transaction or uncertainty as to the impact to our business during the pendency of the Proposed Transaction. Our shareholders will not be able to share in any potential upside that Parent will have by virtue of its ownership of us following the Proposed Transaction.

Lawsuits may be filed against us or our Board of Directors challenging the transactions contemplated by the Merger Agreement or the Proposed Transaction, which could prevent or delay the completion of the Proposed Transaction or result in the payment of damages.

Litigation relating to the Merger Agreement or the Proposed Transaction may be filed against us or our Board of Directors. Among other remedies, claimants could seek damages and/or to enjoin the transactions contemplated by the Merger Agreement or the Proposed Transaction.

An adverse ruling in any such lawsuit may delay or prevent the transactions contemplated by the Proposed Transaction from being completed. Any such actions may create uncertainty relating to the Proposed Transaction and may be costly and distracting to our management.

Risks Related to Intellectual Property Rights, Litigation, and Cybersecurity

Failure to obtain or maintain the right to use certain intellectual property may adversely affect our business, financial condition, results of operations, and cash flows.

Our industries are characterized by frequent litigation regarding patent and other intellectual property rights. From time to time we have received, and may receive in the future, notice of claims of infringement of other parties’ proprietary rights and licensing offers to commercialize third party patent rights. Numerous patents in our industries are held by others, including competitors and certain academic institutions. Competitors may seek to gain a competitive advantage, or other third parties may seek an economic return on their intellectual property portfolios, by making infringement claims against us. We cannot be certain that:

•infringement claims (or claims for indemnification resulting from infringement claims) will not be asserted against us or that such claims will not be successful;

•future assertions will not result in an injunction against the sale of infringing products, which could require us to cease the manufacture, use or sale of the infringing products, processes, or technology and expend significant resources to develop non-infringing technology, adversely affecting our business, results of operations, and cash flows;

•any patent owned or licensed by us will not be invalidated, circumvented, or challenged; or

•we will not be required to obtain licenses or pay substantial damages for past, present, and future use of the infringing technology, the expense of which may adversely affect results of operations and cash flows.

For example, in June 2018, Phoenix commenced an arbitration against us with the American Arbitration Association (“AAA”) in New York and a special proceeding against us in the New York Supreme Court, Commercial Division. In June 2019, an interim award (the “Interim Award”) was issued in connection with certain of the claims in the AAA proceeding and in October

Table of Contents

2019, the arbitrator issued a Modified Partial Final Award, which incorporated by reference the terms of the Interim Award and ordered and awarded, among other items, (a) an award to Phoenix of attorneys’ fees and costs in the amount of approximately $3.8 million, (b) an award to Phoenix of $1.0 million in damages owing for unpaid royalties through June 30, 2019, (c) an award to Phoenix of $0.1 million in prejudgment interest, calculated at the New York statutory rate of 9% simple interest; and (d) payment to Phoenix of a royalty of 7.5% of the sale price on (i) future customer payments for certain of our product contracts entered into prior to the Interim Award and (ii) customer payments for future sales of any product using any of the five trade secret subparts deemed in the Interim Award to have been misappropriated by us (collectively, the “Deemed Trade Secrets”), in each case payable in a single lump sum within one month of completion of the calendar quarter in which payment has been received from the customer, subject to certain limitations, until such time as we have in good faith determined, and can so document, that we have completely ceased use of the Deemed Trade Secrets.

In addition, effective copyright and trade secret protection may be unavailable or limited in certain foreign jurisdictions. Litigation, which could result in substantial cost and diversion of resources, may be necessary to defend our rights or defend us against claimed infringement of the rights of others. In certain circumstances, our intellectual property rights associated with government contracts may be limited.

If we fail to protect, or incur significant costs in defending, our intellectual property and other proprietary rights, our business and results of operations could be materially harmed.

Success depends to a significant degree on the ability to protect our intellectual property and other proprietary rights. We rely on a combination of patent, trademark, trade secret, and unfair competition laws, as well as license agreements and other contractual provisions, to establish and protect our intellectual property and other proprietary rights. We have applied for patent registrations in the U.S. and selected international jurisdictions, most of which have been issued. We cannot guarantee that pending applications will be approved by the applicable governmental authorities. Moreover, existing and future patents and trademarks may not be sufficiently broad to protect our proprietary rights or may be held invalid or unenforceable in court. Failure to obtain patent registrations or a successful challenge to our registrations in the U.S. or other foreign countries may limit the ability to protect the intellectual property rights that these applications and registrations are intended to cover.

We also attempt to protect our intellectual property, including our trade secrets and know-how, through the use of trade secret and other intellectual property laws, as well as contractual provisions. We enter into confidentiality and invention assignment agreements with employees and independent consultants. We also use non-disclosure agreements with other third parties who may have access to our proprietary technologies and information. Such measures, however, provide only limited protection, and we cannot be certain that our confidentiality and non-disclosure agreements will not be breached, especially after employees end their employment or engagement with us or with them, and that our trade secrets will not otherwise become known by competitors or that we will have adequate remedies in the event of unauthorized use or disclosure of proprietary information. Unauthorized third parties may try to copy or reverse engineer our products or portions of our products, otherwise obtain and use our intellectual property, or may independently develop similar or equivalent trade secrets or know-how. If we fail to protect our intellectual property and other proprietary rights, or if such intellectual property and proprietary rights are infringed or misappropriated, we could lose our competitive advantage and our business, results of operations, financial condition, and cash flows could be materially harmed.

Policing unauthorized use of our technology is difficult, and we cannot be certain that the steps we have taken will prevent the misappropriation, unauthorized use, or other infringement of our intellectual property rights. Further, we may not be able to effectively protect our intellectual property rights from misappropriation or other infringement in foreign countries where we have not applied for patent protections, and where effective patent, trademark, trade secret, and other intellectual property laws may be unavailable, or may not protect our proprietary rights as fully as U.S. law.

In the future, we may need to take legal actions to prevent third parties from infringing upon or misappropriating our intellectual property or from otherwise gaining access to our technology. Protecting and enforcing our intellectual property rights and determining their validity and scope could result in significant litigation costs and require significant time and attention from our technical and management personnel, which could significantly harm our business. The availability of financial resources may limit the ability to commence or defend such litigation. In addition, we may not prevail in such proceedings. An adverse outcome of such proceedings may reduce our competitive advantage or otherwise harm our business, financial condition, results of operations, and cash flows.

We may be obligated to indemnify customers and vendors for claims that our intellectual property infringes the rights of others, which may result in substantial expense to us.

Table of Contents

We may be required to indemnify customers or vendors for intellectual property claims made against them for products incorporating our technology. As such, claims against customers and vendors may require us to incur substantial expenses, such as legal expenses, damages for past infringement, or royalties for future use. Future indemnity claims could adversely affect business relationships and result in substantial costs to us.

We face certain litigation risks that could harm our business.

We may become subject to various legal proceedings and claims that arise in or outside the ordinary course of business. The results of legal proceedings are difficult to predict. Moreover, complaints that may be filed against us may not specify the amount of damages that plaintiffs seek, and we therefore may be unable to estimate the possible range of damages that might be incurred should these lawsuits be resolved against us. If any litigation is resolved against us, we could be subject to substantial damages. Thus, an unfavorable outcome or settlement of one or more lawsuits may have an adverse effect on our business, financial condition, results of operations, and cash flows. Even if litigation is not resolved against us, the uncertainty and expense associated with unresolved lawsuits could seriously harm our business, financial condition, and reputation. Litigation is costly, time-consuming, and disruptive to normal business operations.

Costs of defending litigation have been significant in the past, may continue, and may not be covered by our insurance policies. The defense of litigation could also result in diversion of management’s time and attention away from business operations, which could harm our business.

We could be subject to legal consequences if we fail to comply with the Modified Partial Final Award issued in connection with the Phoenix legal proceedings.

In the Interim Award incorporated by reference into the Modified Partial Final Award the arbitrator determined and ordered that we are required to pay Phoenix a royalty of 7.5% of the sale price on (a) future customer payments for certain of our product contracts previously entered into at the time the Interim Award was issued and (b) customer payments for future sales of any product using any Deemed Trade Secret, in each case payable in a single lump sum within one month of completion of the calendar quarter in which payment has been received from the customer, and we are required to concurrently submit to Phoenix a written report that sets forth the calculation of the amount of the royalty payment in a form similar to previous royalty reports. We are required to continue to make royalty payments in this manner until such time as we have in good faith determined, and can so document, that we have completely ceased use of the Deemed Trade Secrets, and must provide notice of this determination to Phoenix. It is possible that additional legal proceedings will follow in connection with delivery of this notice to Phoenix, which would require us to incur additional costs and divert management’s attention. If we fail to comply with these obligations, we could be subject to additional claims, penalties, or judgments, which could harm our business, financial condition, results of operations, and cash flows. In addition, we could be subject to significant legal costs and expenses in connection with the interpretation of certain of the obligations pursuant to the Interim Award, which could harm our business, financial condition, results of operations, and cash flows.

Our business and operations could be adversely impacted in the event of a failure or security breach of our information technology infrastructure.

We rely upon the capacity, reliability, and security of our information technology hardware and software infrastructure and the ability to expand and update this infrastructure in response to changing needs. We are constantly updating our information technology infrastructure. Although we have a disaster recovery plan, any failure to manage, expand, and update our information technology infrastructure or any failure in the operation of this infrastructure could harm our business. In addition, we may be subject to a heightened risk of potential security breaches due to our sales to, and work with, government customers and the technologies that we develop for the defense industry.

The secure maintenance of this information is critical to our business and reputation. Despite implementation of security measures, systems are vulnerable to damages from computer viruses, computer denial-of-service attacks, worms, and other malicious software programs or other attacks, covert introduction of malware to computers and networks, unauthorized access, including impersonation of unauthorized users, efforts to discover and exploit any security vulnerabilities or securities weaknesses, and other similar disruptions. These types of attacks have increased, in general, as more businesses implement remote working environments. Our business is also subject to break-ins, sabotage, and intentional acts of vandalism by third parties as well as intentional and unintentional acts by employees or other insiders with access privileges. Customers’ network and storage applications may be subject to similar disruptions. It is often difficult to anticipate or immediately detect such incidents and the damage caused by such incidents. Data breaches and any unauthorized access or disclosure of information, employee information, or intellectual property could compromise our intellectual property, trade secrets, and other sensitive

Table of Contents

business information, any of which could result in legal action against us, exposure of our intellectual property to competitors, damages, fines, and other adverse effects. A data security breach could also lead to public exposure of personal information of employees, customers, and others. Any such theft, loss, or misuse of personal data collected, used, stored, or transferred by us to run our business could result in significantly increased security costs or costs related to defending legal claims.

Cyberattacks, such as computer viruses, or other forms of cyber terrorism, may disrupt access to our network or storage applications. Such disruptions could result in delays or cancellations of customer orders or delays or interruptions in the production or shipment of products. Data security breaches involving data center customers could affect their financial condition and ability to continue to purchase our products. In addition, cyberattacks may cause us to incur significant remediation costs, result in product development delays, disrupt key business operations, and divert attention of management and key information technology resources. These incidents could also subject us to liability, expose us to significant expense, and cause significant harm to our reputation and our business.

In addition, our technology infrastructure and systems are vulnerable to damage or interruption from natural disasters, power loss, and telecommunications failures. Our products contain sophisticated hardware and operating system software and applications that may contain security problems, security vulnerabilities, or defects in design or manufacture including “bugs” and other problems that could interfere with the intended operation of our products. To the extent that any disruption or security breach results in a loss or damage to our technology infrastructure, systems, or data or inappropriate disclosure of confidential information or sensitive or personal information, it could harm relationships with customers and other third parties and damage our brand and reputation and our business. In addition, we may be required to incur significant costs to protect against damage caused by these disruptions or security breaches in the future.

We may be subject to theft, loss, or misuse of personal data about employees, customers, or other third parties, which could increase expenses, damage our reputation, or result in legal or regulatory proceedings.

The theft, loss, or misuse of personal data collected, used, stored, or transferred by us to run our business could result in significantly increased security costs or costs related to defending legal claims. Global privacy legislation, enforcement, and policy activity in this area are rapidly expanding and creating a complex compliance regulatory environment. Costs to comply with and implement these privacy-related and data protection measures could be significant. In addition, our inadvertent failure to comply with federal, state, or international privacy related or data protection laws and regulations could result in proceedings against us by governmental entities or others or cause us to incur penalties or other significant legal liability or change business practices.

Risks Related to Governmental Regulation

We could be subject to legal and regulatory consequences if we fail to comply with applicable export control laws and regulations.

Exports of certain products are subject to export controls imposed by the U.S. government and administered by the U.S. Departments of State and Commerce. In certain instances, these regulations may require pre-shipment authorization from the administering department. For products subject to the Export Administration Regulations (“EAR”) administered by the Department of Commerce’s Bureau of Industry and Security, the requirement for a license is dependent on the type and end use of the product, the final destination, the identity of the end user, and whether a license exception might apply. Virtually all exports of products subject to the International Traffic in Arms Regulations (“ITAR”) administered by the Department of State’s Directorate of Defense Trade Controls, require a license.

Obtaining necessary export licenses can be difficult and time-consuming. Failure to obtain necessary export licenses could significantly reduce revenue and adversely affect our business, financial condition, results of operations, and cash flows. We could be subject to investigation and potential regulatory consequences, including, but not limited to, a no-action letter, monetary penalties, debarment from government contracting, or denial of export privileges and criminal sanctions, any of which would adversely affect our business, financial condition, results of operations, and cash flows. Compliance with U.S. government regulations may also subject us to significant fees and expenses, including legal expenses, and require us to expend significant time and resources. Finally, the absence of comparable restrictions on competitors in other countries may adversely affect our competitive position.

We are subject to extensive government regulation, and failure to comply with applicable regulations could subject us to penalties that may restrict the ability to conduct business.

Table of Contents

As a contractor and/or subcontractor to the U.S. government, we are subject to and must comply with various government regulations that impact revenue, operating costs, profit margins, and the internal organization and operation of our business. The most significant regulations and regulatory authorities affecting the portion of our business related to U.S. government contracts include the following:

•the Federal Acquisition Regulations, Defense Federal Acquisition Regulation Supplement, and other supplemental agency regulations which comprehensively regulate the formation and administration of, and performance under, U.S. government contracts;

•the Truth in Negotiations Act which requires certification and disclosure of all factual cost and pricing data in connection with contract negotiations;

•the False Claims Act and the False Statements Act which impose penalties for payments made on the basis of false facts provided to the government and on the basis of false statements made to the government, respectively; and

•the FCPA which prohibits U.S. companies from providing anything of value to a foreign official to help obtain, retain, or direct business, or obtain any unfair advantage.

Failure to comply with applicable regulations, rules and approvals, or misconduct by any employee, could result in the imposition of fines and penalties, the loss of government contracts, or suspension or debarment from contracting with the U.S. government generally, any of which could harm our business, financial condition, results of operations, and cash flows. We are also subject to certain regulations of comparable government agencies in other countries, and failure to comply with these non-U.S. regulations could also harm our business, financial condition, results of operations, and cash flows.

Our business related to government contracts subjects us to additional risks.

We believe that for the foreseeable future our growth will depend, to a certain degree, on the ability to win government contracts and subcontracts, in particular from the Department of Defense. Many government customers are subject to budgetary constraints and our continued performance under these contracts or subcontracts, or award of additional contracts or subcontracts from these agencies, could be jeopardized by spending reductions, including constraints on government spending imposed by the Budget Control Act of 2011 and its subsequent amendments, budget cutbacks at these agencies, or government shutdowns. The funding of U.S. government programs is uncertain and dependent on continued congressional appropriations and administrative allotment of funds based on an annual budgeting process. We cannot be certain that current levels of congressional funding for our products and services will continue and that our business related to these products will not decline or increase at currently anticipated levels, or that we will not be subject to delays in the negotiation of contracts or increased costs due to changes in the funding of U.S. government programs or government shutdowns. A significant decline in government expenditures generally, or with respect to programs for which we provide products, could adversely affect our business and prospects. In addition, U.S. government contracts generally permit the government to terminate the contract without prior notice, at the government’s convenience, or for default based on performance. Government customers can also decline to exercise previously disclosed contract options. A termination arising out of our default could expose us to liability and adversely affect our ability to obtain future contracts and orders. Furthermore, on contracts for which we are a subcontractor and not the prime contractor, the U.S. government could terminate the prime contract for convenience or otherwise, irrespective of our performance as a subcontractor. Also, sales to the U.S. government and its contractors as well as foreign military and government customers, either directly or as a subcontractor to other contractors, often use a competitive bidding process and have unique purchasing and delivery requirements, which often makes the timing of sales to these customers unpredictable.

In addition, our business could be adversely affected by a negative audit or investigation by the U.S. government. U.S. government agencies, primarily the Defense Contract Audit Agency and the Defense Contract Management Agency, routinely audit and investigate government contractors. These agencies review a contractor’s performance under its contracts, cost structure, and compliance with applicable laws, regulations, and standards. These agencies also may review the adequacy of, and a contractor’s compliance with, its internal control systems and policies, including the contractor’s purchasing, quality, accounting, property, estimating, compensation, and management information systems. Any costs found to be improperly allocated to a specific cost reimbursement contract will not be reimbursed, while such costs already reimbursed must be refunded. If an audit or investigation of our business were to uncover improper or illegal activities, then we could be subject to civil and criminal penalties and administrative sanctions, including termination of contracts, suspension of payments, fines, and suspension or debarment from doing business with the U.S. government. We could experience serious harm to our reputation if allegations of impropriety or illegal acts were made against us, even if the allegations were inaccurate. In addition, responding to governmental audits or investigations may involve significant expense and divert management attention. Moreover, if any administrative processes and business systems are found not to comply with the applicable requirements, we may be subject to increased government scrutiny or required to obtain additional governmental approvals that could delay or otherwise adversely affect the ability to compete for or perform contracts. If any of the foregoing were to occur, our business, financial condition, operating results, and cash flows may be adversely affected.

The costs of compliance with state, federal, and international legal and regulatory requirements, such as environmental, labor, trade, and tax regulations, and customers’ standards of corporate citizenship could increase operating costs.

We are subject to environmental and health and safety laws and regulations and must obtain certain permits and licenses relating to the use of hazardous materials in production activities. If control systems are unsuccessful in preventing a release of these materials into the environment or other adverse environmental conditions or human exposure occurs, we could experience interruptions in operations and incur substantial remediation and other costs or liabilities. We are also subject to a number of federal and state laws and regulations related to safety, including the Occupational Safety and Health Administration (“OSHA”) and comparable state statutes, the purposes of which are to protect the health and safety of workers. Failure to comply with OSHA requirements and other related state regulations, including general industry standards, record keeping requirements, and monitoring and control of occupational exposure to regulated substances, could have a material adverse effect on results of operations and financial condition if we are subjected to significant penalties, fines, or compliance costs. In addition, certain foreign laws and regulations place restrictions on the concentration of certain hazardous materials, including, but not limited to, lead, mercury, and cadmium, in our products. Failure to comply with such laws and regulations could subject us to future liabilities or result in the limitation or suspension of the sale or production of our products. These regulations include the EU’s Restrictions on Hazardous Substances and Directive on Waste Electrical and Electronic Equipment. Failure to comply with environmental and health and safety laws and regulations may limit the ability to export products to the EU and could adversely affect our business, financial condition, results of operations, and cash flows. In addition, we purchase certain chemicals from Europe and Asia that are unique, nearing the end of life, and could be subject to future changes to environmental regulations in the country of origin and/or the U.S. In the event new restrictions are placed on any such chemicals, they may be difficult to replace, and may require us to re-design or re-validate existing products that use such chemicals in their production.

In connection with compliance with such environmental laws and regulations, as well as compliance with industry environmental initiatives, the standards of business conduct required by some customers, and our commitment to sound corporate citizenship in all aspects of our business, we could incur substantial compliance and operating costs and be subject to disruptions to operations. In addition, in recent years, there has been increased media scrutiny and associated reports focusing on a potential link between working in semiconductor manufacturing clean room environments and certain illnesses, primarily different types of cancers. Regulatory agencies and industry associations have begun to study the issue to see if any actual correlation exists. Because we utilize clean rooms, we may become subject to liability claims. These reports may also affect the ability to recruit and retain employees. If we were found to be in violation of environmental and safety regulations laws or noncompliance with industry initiatives or standards of conduct, we could be subject to government fines or liabilities owed to customers, which could have an adverse effect on our business, financial condition, results of operations, and cash flows.

In addition, climate change is a significant topic of discussion and potential regulatory activity and has generated and may continue to generate federal or other regulatory responses in the near future. If we or component suppliers fail to timely comply with applicable legislation, customers may refuse to purchase products or we may face increased operating costs as a result of taxes, fines, or penalties, which may have an adverse effect on our business, financial condition, results of operations, and cash flows.

The Department of Homeland Security has commenced a program to evaluate the security of certain chemicals which may be of interest to terrorists, including chemicals utilized by us. This evaluation may lead to regulations or restrictions affecting the ability to utilize these chemicals or the costs of doing so.

We are subject to anti-corruption laws in the jurisdictions in which we operate, including the FCPA. Failure to comply with these laws could result in penalties which could harm our reputation and have an adverse effect on our business, results of operations, and financial condition.

We are subject to the FCPA, which generally prohibits companies and their intermediaries from making improper payments to foreign officials for the purpose of obtaining or keeping business and/or other benefits, along with various other anti-corruption laws. Although we have implemented policies and procedures designed to ensure that we, our employees, and other intermediaries comply with the FCPA and other anti-corruption laws to which we are subject, we cannot be certain that such policies or procedures will work effectively all of the time or protect us against liability under the FCPA or other laws for actions taken by employees and other intermediaries with respect to our business or any businesses that we may acquire.

We export products for sale internationally. This puts us in frequent contact with persons who may be considered “foreign officials” under the FCPA, resulting in an elevated risk of potential FCPA violations. If we are not in compliance with the FCPA and other laws governing the conduct of business with government entities (including local laws), we may be subject to criminal and civil penalties and other remedial measures, which could have an adverse impact on our business, financial

condition, results of operations, and cash flows. Any investigation of any potential violations of the FCPA or other anti-corruption laws by U.S. or foreign authorities could harm our reputation and have an adverse impact on our business, financial condition, results of operations, and cash flows.

We have identified material weaknesses in our system of internal controls over financial reporting and have concluded that our disclosure controls and procedures were not effective as of September 30, 2024 and 2023. If we fail to properly remediate the material weaknesses or any future deficiencies or material weaknesses or to maintain proper and effective internal controls, material misstatements in our financial statements could occur and impair our ability to produce accurate and timely financial statements and could adversely affect investor confidence in our financial reports, which could negatively affect our business.

We are subject to the ongoing internal control provisions of Section 404 of the Sarbanes-Oxley Act of 2002. These provisions provide for the identification of material weaknesses or other lesser deficiencies in internal control over financial reporting, which is a process to provide reasonable assurance regarding the reliability of financial reporting for external purposes in accordance with GAAP.

In connection with the preparation of our Annual Report on Form 10-K for the fiscal years ended September 30, 2024 and 2023, we identified material weaknesses in internal control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

As more fully described in Item 9A. “Controls and Procedures”, we determined that the material weakness as of September 30, 2024 related to insufficient resources, particularly a lack of qualified project accounting and cost accounting personnel. This control deficiency resulted in untimely preparation and review of account reconciliations by staff untrained in these areas. In particular, our review of certain liability and asset accounts within the Company’s consolidated balance sheet was not sufficient to ensure that these accounts, along with revenue and cost of revenues within the Company’s statement of operations and comprehensive loss, reflected accurate amounts based on reconciliations and supporting documentation. These errors were corrected in the consolidated financial statements as of and for the fiscal year ended September 30, 2024, and as a result, this material weakness did not result in a material misstatement to the consolidated financial statements included in this Annual Report on Form 10-K.

As more fully described in Item 9A. “Controls and Procedures”, we determined that the material weakness as of September 30, 2023 related to communications with regard to internal control objectives were not effective to require employees to report the existence of new or novel arrangements for technical accounting review, which resulted in our failure to design and implement effective controls over such transactions. The control deficiency resulted in a material error associated with identification of the existence of certain insurance premium and supplier financing agreements, whereby (i) certain items on our consolidated balance sheet were underreported in “Other current assets” with a consistent dollar amount underreported for “Financing payable” within our consolidated balance sheet and (ii) certain items on our consolidated statements of cash flows were underreported in payments to financing payables within “Cash flows from financing activities” and similar such underreporting of such items in other assets in “Cash flows from operating activities”. This error was corrected in the consolidated financial statements as of and for the fiscal year ended September 30, 2023, and as a result, this material weakness did not result in a material misstatement to the annual or interim consolidated financial statements previously filed and/or included in this Annual Report on Form 10-K. This material weakness has not been remediated as of September 30, 2024.

Although we have identified and are implementing actions intended to improve the effectiveness of our internal control over financial reporting and disclosure controls and procedures as more fully described in Item 9A. “Controls and Procedures”, and will continue to do so until such remediation is complete, there is no assurance that the actions we take will remediate the material weaknesses.

We can give no assurance that additional material weaknesses will not arise in the future. Any failure to remediate the material weakness, or the development of new material weaknesses in our internal control over financial reporting, could result in material misstatements in our financial statements. We cannot be certain that the improvement measures taken will ensure adequate controls over financial processes and reporting in the future. Any failure to implement required, new, or improved controls, or difficulties encountered in their implementation, could harm operating results or cause us to fail to meet reporting obligations. This could cause us to fail to meet our reporting and financial obligations, which in turn could have a negative impact on our financial condition, results of operations or cash flows, restrict our ability to access the capital markets, require significant resources to correct the material weaknesses or deficiencies, subject us to fines, penalties or judgments, or harm our reputation.

Table of Contents

Inadequate internal controls could also cause investors to lose confidence in our reported financial information, which could have an adverse effect on the trading price of our equity securities. Further, the impact of these events could also make it more difficult for us to attract and retain qualified persons to serve on the Board of Directors or as executive officers, which could harm our business.

Our internal control over financial reporting may not prevent or detect misstatements because of its inherent limitations, including the possibility of human error, failure or interruption of information technology systems, the circumvention or overriding of controls, or fraud. Even effective internal controls can provide only reasonable assurance with respect to the preparation and fair presentation of financial statements. If we fail to maintain the adequacy of our internal controls, including any failure to implement required new or improved controls, or if we experience difficulties in their implementation, our business and operating results could be harmed and the Company could fail to meet its financial reporting obligations.

We could be required to record an impairment charge as a result of changes to assumptions used in our impairment testing.

We have substantial long-lived assets recorded on the balance sheet. If we make changes in our business strategy or if market or other conditions adversely affect business operations, we may be forced to record an impairment charge related to these assets, which would adversely impact results of operations. Impairment assessment inherently involves judgment as to assumptions about expected future cash flows and the impact of market conditions on those assumptions. Future events and changes in market conditions, underlying business operations, competition, or technologies may impact assumptions as to prices, costs, holding periods, or other factors that may result in changes in estimates of future cash flows. Although we believe the assumptions we used in testing for impairment are reasonable, we will continue to evaluate the recoverability of the carrying amount of definite-lived intangible assets and property, plant and equipment on an ongoing basis, and test indefinite-lived intangible assets annually or more frequently as indicated, and significant changes in any one assumption could produce a significantly different result. In such a circumstance, we may incur substantial impairment charges, which would adversely affect financial results. In any period where our stock price, as determined by market capitalization, is less than book value, this too could indicate a potential impairment and we may be required to record an impairment charge in that period.

Compliance with regulations related to conflict minerals and other regulations with respect to our supply chains could increase costs and affect the manufacturing and sale of our products.

Public companies are required to disclose the use of tin, tantalum, tungsten and gold (collectively, “conflict minerals”) mined from the Democratic Republic of the Congo and adjoining countries (the “covered countries”) if a conflict mineral(s) is necessary to the functionality of a product manufactured, or contracted to be manufactured, by us. We may determine, as part of compliance efforts, that certain products or components we obtain from suppliers contain conflict minerals. If we are unable to conclude that all products are free from conflict minerals originating from covered countries, this could have a negative impact on our business, reputation, and/or results of operations. We may also encounter challenges to satisfy customers who require that products be certified as conflict free, which could place us at a competitive disadvantage. Compliance with these rules could also affect the sourcing and availability of some of the minerals used in the manufacture of products or components we obtain from suppliers, including the ability to obtain products or components in sufficient quantities and/or at competitive prices. Certain customers are requiring additional information from us regarding the origin of raw materials and complying with these customer requirements may cause us to incur additional costs. Our supply chain is complex and we may be unable to verify the origins for all metals used in products.

In addition, the U.S. federal government has issued policies for federal procurement focused on eradicating the practice of forced labor and human trafficking, and the United Kingdom and the State of California have issued laws that require us to disclose our policy and practices for identifying and eliminating forced labor and human trafficking in our supply chain. Several customers, as well as the Electronic Industry Citizenship Coalition, have also issued expectations to eliminate these practices that may impact us. While we have a policy and management systems to identify and avoid these practices in our supply chain, we cannot guarantee that suppliers will always be in conformance to these laws and expectations. We may face enforcement liability and reputational challenges if we are unable to sufficiently meet these expectations. Moreover, we are likely to encounter challenges with customers if we cannot satisfy their forced and trafficked labor policies and they may choose a competitor’s product.

We may undergo an “ownership change” within the meaning of Section 382 of the Code, which could affect our ability to offset U.S. federal income tax against our net operating losses and certain of our tax credit carryovers.

In September 2023, our Board of Directors adopted the Section 382 Tax Benefits Preservation Plan to diminish the risk that we could experience an “ownership change” as defined in Section 382 (“Section 382”) of the Internal Revenue Code of 1986, as

Table of Contents

amended (the “Code”), which could substantially limit or permanently eliminate our ability to utilize our net operating loss carryovers (collectively, the “NOLs”) to reduce potential future income tax obligations. Under the Code and the regulations promulgated thereunder by the U.S. Treasury Department, these NOLs may be “carried forward” in certain circumstances to offset any current and future taxable income and thus reduce federal income tax liability, subject to certain requirements and restrictions. The Company believes that on February 14, 2024, an “ownership change” occurred under Section 382, resulting in a decrease of total remaining federal NOLs to approximately $50.0 million and imposing an annual limit on the amount of the Company’s NOLs that can be used to offset the Company’s federal taxable income equal to $793 thousand for the subsequent 14-year period. If an additional ownership change were to occur, the limitations imposed by Section 382 could result in a substantial delay in the timing of the usage of the remaining NOLs or in a material amount or all of the remaining NOLs expiring unused and, therefore, significantly impair or eliminate the value of such NOLs. While the Company periodically monitors its NOLs, the complexity of Section 382’s provisions and the limited knowledge any public company has about the ownership of its publicly traded stock make it difficult to determine whether an ownership change has in fact occurred. While the amount and timing of our future taxable income cannot be predicted with any certainty and, accordingly, we cannot predict the amount of these NOLs that will ultimately be used to reduce its income tax liability, to the extent that the NOLs do not otherwise become limited, these NOLs could be a potentially valuable asset to us. As of September 30, 2024, we had federal net operating loss carryforwards of approximately $373.9 million.

In general, under Section 382, an “ownership change” occurs if a shareholder or a group of shareholders who are deemed to own at least 5% of a company’s stock individually or collectively increase their ownership by more than 50 percentage points over their lowest ownership percentage within a rolling three-year period. If another ownership change occurs, Section 382 would impose an annual limit on the amount of the Company’s NOLs that can be used to offset the Company’s federal taxable income equal to the product of the total value of the Company’s outstanding equity immediately prior to the ownership change (reduced by certain items specified in Section 382) and the federal long-term tax-exempt interest rate in effect for the month of the ownership change. A number of complex rules apply to calculating this annual limit and there are several special rules that, depending on the rule involved, may apply to reduce or increase such limit. If we were to undergo one or more additional “ownership changes” within the meaning of Section 382 of the Code, our NOLs and certain of our tax credits existing as of the date of each ownership change may be unavailable, in whole or in part, to offset U.S. federal income tax resulting from our operations or any gains from the disposition of any of our assets and/or business, which could result in increased U.S. federal income tax liability. Furthermore, there is no assurance that we will be able to fully utilize our NOLs and we may be required to record an additional valuation allowance related to the amount of the NOLs that may not be realized.

The Section 382 Tax Benefits Preservation Plan is intended to act as a deterrent to any person or group acquiring beneficial ownership of 4.99% or more of our outstanding common stock without the approval of the Board of Directors. A person who acquires, without the approval of the Board of Directors, beneficial ownership (other than as a result of repurchases of stock by the Company, dividends or distributions by the Company or certain inadvertent actions by shareholders) of 4.99% or more of the outstanding common stock (including any ownership interest held by that person’s Affiliates and Associates as defined under the Section 382 Tax Benefits Preservation Plan) could be subject to significant dilution. Although the Section 382 Tax Benefits Preservation Plan is intended to reduce the likelihood of an “ownership change” that could adversely affect us, there is no assurance that the restrictions on transferability in the rights plan will prevent all transfers that could result in such an “ownership change”. The Section 382 Tax Benefits Preservation Plan could make it more difficult for a third party to acquire, or could discourage a third party from acquiring, our Company or a large block of our common stock. A third party that acquires 4.99% or more of our common stock could suffer substantial dilution of its ownership interest under the terms of the Section 382 Tax Benefits Preservation Plan through the issuance of common stock or common stock equivalents to all shareholders other than the acquiring person. The foregoing provisions may adversely affect the marketability of our common stock by discouraging potential investors from acquiring our stock. In addition, these provisions could delay or frustrate the removal of incumbent directors and could make more difficult a merger, tender offer or proxy contest involving us, or impede an attempt to acquire a significant or controlling interest in us, even if such events might be beneficial to us and our shareholders.

Certain provisions of New Jersey law and our governing documents may make a takeover of our Company difficult even if such takeover could be beneficial to shareholders.

Certain provisions of our organizational documents and New Jersey law could discourage potential acquisition proposals, delay, or prevent a change in control of the Company, or limit the price that investors may be willing to pay in the future for shares of common stock. For example, our amended and restated certificate of incorporation and amended and restated bylaws:

•provide that directors may be removed at any time, but only for cause and only by the affirmative vote of the holders of at least a majority of outstanding shares of capital stock entitled to vote generally in the election of directors cast at a meeting of shareholders called for that purpose;

Table of Contents

•provide that a super majority vote of shareholders is required to amend some portions of our amended and restated certificate of incorporation and amended and restated bylaws, including requiring approval by the holders of 80% or more of the outstanding shares of capital stock entitled to vote generally in the election of directors for certain business combinations unless these transactions meet certain fair price criteria and procedural requirements or are approved by two-thirds of continuing directors;

•authorize the issuance of preferred stock, without any requirement of vote or class vote of shareholders, commonly referred to as “blank check” preferred stock, which shares of preferred stock may have rights senior to those of common stock;

•limit the persons who can call special shareholder meetings; shareholders do not have authority to call a special meeting of shareholders;

•establish advance notice requirements that must be complied with by shareholders to nominate persons for election to the Board of Directors or to propose matters that can be acted on by shareholders at shareholder meetings;

•do not provide for cumulative voting in the election of directors; and

•provide for the filling of vacancies on the Board of Directors by action of 66 2/3% of the directors and not by the shareholders.

These and other provisions in our organizational documents could allow the Board of Directors to affect the rights of shareholders in a number of ways, including making it difficult for shareholders to replace members of the Board of Directors. Because the Board of Directors is responsible for approving the appointment of members of the management team, these provisions could in turn affect any attempt to replace the current management team. These provisions could also limit the price that investors would be willing to pay in the future for shares of common stock. We may in the future adopt other measures that may have the effect of delaying or discouraging an unsolicited takeover, even if the takeover were at a premium price or favored by a majority of unaffiliated shareholders. Certain of these measures may be adopted without any further vote or action by shareholders and this could depress the price of our common stock.

General Risk Factors

If we fail to satisfy all applicable Nasdaq continued listing requirements our common stock may be delisted from Nasdaq, which could have an adverse impact on the liquidity and market price of our common stock.

Our common stock is currently listed on Nasdaq, which has qualitative and quantitative continued listing requirements, including corporate governance requirements, public float requirements, and a $1.00 minimum closing bid price requirement. If we fail to satisfy all applicable Nasdaq continued listing requirements and our common stock is delisted, it would likely have an adverse effect on the liquidity of our common stock, decrease the market price of our common stock, result in the potential loss of confidence by investors, suppliers, customers, and employees, and fewer business development opportunities, and adversely affect our ability to obtain financing for our continuing operations.

Our business and results of operations may continue to be negatively impacted by general economic and financial market conditions and market conditions in the industries in which we operate, and such conditions may increase the other risks that affect our business.

In recent years, the world’s financial markets have experienced significant turmoil, resulting in reductions in available credit, increased costs of credit, extreme volatility in security prices, potential changes to existing credit terms, and rating downgrades of investments. These conditions have and may continue to materially and adversely affect the market conditions in the industries in which we operate and cause many customers to reduce their spending plans, leading them to draw down their existing inventory, and reduce orders for our products, which, in turn, may adversely impact our revenues. We cannot predict the timing, strength, or duration of any economic slowdown or subsequent economic recovery, worldwide or within our industries. It is possible that adverse macroeconomic developments, including inflation, slowing growth or recession, and rising interest rates, could result in further setbacks, and that these customers, or others, could as a result, significantly reduce their capital expenditures, draw down their inventories, reduce production levels of existing products, defer introduction of new products, or place orders and accept delivery for products for which they do not pay us due to their economic difficulties or other reasons. If any of these events occur, our business, financial condition, results of operations, and cash flows may be adversely affected. Management continues to evaluate the impact of macroeconomic events, including inflation, on our business and our future plans and intends to take appropriate measures to help alleviate their impact, but there can be no assurance that these efforts will be successful. A weak or declining economy could also strain our suppliers, possibly resulting in supply disruption, or cause our customers to delay making payments for our products. A severe or prolonged economic downturn, such as the global financial crisis, could also reduce our ability to raise additional capital when needed on acceptable terms, if at all.

Table of Contents

Further, the funding of the defense programs that incorporate our products and services is subject to the overall U.S. government budget and appropriation decisions and processes, which are driven by numerous factors beyond our control, including geo-political, macroeconomic, public health and political conditions. We are unable to predict the likely duration and severity of adverse economic conditions in the U.S. and other countries, but the longer the duration or the greater the severity, the greater the risks we face in operating our business. The near-term potential for recessionary economic conditions and possible stagflation (persistent high inflation and stagnant economic demand) presents increased risks to our business.

Natural disasters or other catastrophic events could have an adverse effect on our business.

Natural disasters such as hurricanes, earthquakes, fires, and floods, could adversely affect operations and financial performance. Such events could result in physical damage to one or more facilities, the temporary closure of one or more facilities or those of our suppliers, a temporary lack of an adequate work force in a market, a temporary or long-term disruption in the supply of products from some local and overseas suppliers, a temporary disruption in the transportation of goods from overseas, and delays in the delivery of goods. Public health issues, such as the COVID-19 pandemic, whether occurring in the U.S. or abroad, could disrupt our operations, disrupt the operations of suppliers or customers, or have an adverse impact on customer demand. As a result of any of these events, we may be required to suspend operations in some or all locations, which could have an adverse effect on our business, financial condition, results of operations, and cash flows. These events could also reduce demand for our products or make it difficult or impossible to receive products from suppliers. Although we maintain business interruption insurance and other insurance intended to cover some of these risks, such insurance may be inadequate, whether because of coverage amount, policy limitations, the financial viability of the insurance companies issuing such policies, or other reasons.

***

The risks above are not the only risks we face. If any of the events described in our risk factors actually occur, or if additional risks and uncertainties not presently known to us or that we currently deem immaterial materialize, then our business, financial condition, results of operations, and cash flows could be materially affected.

ITEM 1C. Cybersecurity.

We recognize the importance of cybersecurity in achieving our business objectives, safeguarding our assets, and managing our daily operations. Accordingly, we integrate a process for identifying, assessing, and managing material risks from cybersecurity threats into our overall risk management system. The Audit Committee of our Board of Directors oversees all matters related to the security of and risks related to information technology systems and procedures, including cybersecurity policies and procedures.

Our cybersecurity program, including the prevention, detection, investigation, and response to cybersecurity threats and incidents, is managed by our Director, IT, who has worked in information technology and communications services for over 25 years. Our cybersecurity program incorporates an incident response plan to engage cross-functionally across the Company and report cybersecurity incidents to appropriate levels of management, including senior management and the Audit Committee or Board of Directors, based on potential impact. Because of the relatively small size of our information technology workforce, we have limited internal cybersecurity expertise and monitoring capabilities; accordingly, we seek to augment our internal capabilities by engaging larger, well-known third-party service providers with significantly greater cybersecurity capabilities than we possess to monitor cybersecurity events and provide rapid responses to any critical events, including with respect to Managed Detection and Response (MDR) and Endpoint Detection & Response (EDR). Because we rely on their more significant expertise, our ability to identify and remediate weaknesses or vulnerabilities is limited to their services. We have engaged with third parties to assess our cybersecurity defenses biweekly and audit our cybersecurity program. We also conduct annual penetration tests of our information systems via independent third-party cybersecurity experts to evaluate our systems and provide remediation and recommendations to improve our cybersecurity program. We also conduct annual cybersecurity awareness training. We aim to incorporate industry best practices throughout our cybersecurity processes, and our cybersecurity framework leverages internationally recognized standards, including the National Institute of Standards and Technology’s (“NIST”) Cybersecurity Framework. We are compliant with DFARS 252.204-7012 and DFARS 252.204-7020 and have a compliant NIST SP 800-171 self-assessment status.

Table of Contents

As of the date of this report, we have not identified any risks from known cybersecurity threats, including as a result of any prior cybersecurity incidents, that have materially affected or are reasonably likely to materially affect the Company, including our business strategy, results of operations, or financial condition.

While we believe our cybersecurity program is appropriate for managing constantly evolving cybersecurity risks, no program can fully protect against all possible adverse events. For additional information on these risks and potential consequences if the measures we are taking prove to be insufficient or if our proprietary data is otherwise not protected, see Item 1A. “Risk Factors” in this report.

Business Overview

We are a leading provider of sensors and navigation systems for the aerospace and defense market. We leverage industry-leading Photonic Integrated Chip (“PIC”) and Quartz Micro Electro-Mechanical System (“QMEMS”) chip-level technology to deliver state-of-the-art component and system-level products across our end-market applications. Over the last six years, we have expanded our scope and portfolio of inertial sensor products through the acquisitions of Systron Donner Inertial, Inc. (“SDI”) in June 2019, the Space and Navigation (“S&N”) business of L3Harris Technologies, Inc. in April 2022, and the Fiber Optic Gyroscope (“FOG”) and Inertial Navigation Systems business (“EMCORE Chicago”) of KVH Industries, Inc. in August 2022. Our multi-year transition from a broadband company to an inertial navigation company has now been completed following the sales of (i) our cable TV, wireless, sensing and defense optoelectronics business lines in October 2023 and (ii) our chips business line and indium phosphide wafer fabrication operations in April 2024.

We have fully vertically-integrated manufacturing capability at our facilities in Budd Lake, NJ (the “Budd Lake Facility”), Concord, CA (the “Concord Facility”), and Tinley Park, IL (the “Tinley Park Facility”). These facilities support our manufacturing strategy for FOG, Ring Laser Gyro (“RLG”), PIC, and QMEMS products for inertial navigation. Our manufacturing facilities maintain ISO 9001 quality management certification, and we are AS9100 aerospace quality certified at the Concord Facility and the Budd Lake Facility.

Aerosphere Power Merger Agreement

Table of Contents

On November 7, 2024, the Company entered into the Merger Agreement with Parent, Parent Group Member, and Merger Sub. The Merger Agreement provides that, subject to the terms and conditions set forth in the Merger Agreement, Merger Sub will merge with and into the Company, with the Company surviving the Merger and becoming an indirect wholly owned subsidiary of Parent.

Our Board of Directors unanimously (i) determined that the transactions contemplated by the Merger Agreement, including the Merger, are advisable, fair to, and in the best interests of the Company and our shareholders; (ii) approved the Merger Agreement and the transactions contemplated by the Merger Agreement; and (iii) recommended that our shareholders vote to adopt and approve the Merger Agreement and the Merger.

Under the Merger Agreement, at the effective time of the Merger, each issued and outstanding share of common stock, no par value, of the Company (subject to certain exceptions set forth in the Merger Agreement) will be converted into the right to receive $3.10 per share (the “Merger Consideration”) in cash, without interest, subject to any withholding taxes. Immediately prior to the effective time of the Merger:

•each outstanding restricted stock unit award subject to time-based vesting restrictions, whether vested or unvested, that is outstanding under any of the Company’s 2010 Equity Incentive Plan, 2012 Equity Incentive Plan, Amended and Restated 2019 Equity Incentive Plan, 2022 New Employee Inducement Plan, Officer and Director Share Purchase Plan, Directors’ Compensation Policy, and Short-Term Incentive Plan, in each case, as amended (each a “Company Equity Plan”) will be canceled in consideration for the right to receive a lump sum cash payment (less any applicable tax withholdings) equal to the product obtained by multiplying (1) the amount of the Merger Consideration by (2) the total number of shares of the Company’s common stock represented by such restricted stock unit award subject to time-based vesting restrictions;

•each outstanding restricted stock unit award subject to performance vesting conditions that is outstanding under any Company Equity Plan (a) to the extent not vested, will be deemed to have satisfied such performance vesting conditions at 100% of target and will have any time-based vesting conditions waived, and (b) will be canceled in consideration for the right to receive a lump sum cash payment (less any applicable tax withholdings) equal to the product obtained by multiplying (1) the amount of the Merger Consideration by (2) the total number of shares of the Company’s common stock represented by such restricted stock unit award subject to performance vesting conditions; and

•each outstanding stock option of the Company (if any), whether vested or unvested, will be canceled and converted into the right to receive (without interest) a lump sum cash payment (less applicable tax withholdings) equal to the product obtained by multiplying (1) the excess, if any, of the amount of the Merger Consideration over the per share exercise price of such stock option by (2) the total number of shares of the Company’s common stock underlying such stock option. Any stock option, whether vested or unvested, for which the per share exercise price attributable to such stock option is equal to or greater than the Merger Consideration will be canceled as of the effective time of the Merger for no consideration.

There are currently no awards outstanding under the 2010 Equity Incentive Plan and the 2012 Equity Incentive Plan, nor are there expected to be any awards outstanding under these plans prior to or at the closing of the Merger.

Consummation of the Merger is subject to the satisfaction or waiver of customary closing conditions, including: (1) the accuracy of the representations and warranties contained in the Merger Agreement, subject to certain customary materiality qualifications, as of the date of the Merger Agreement and as of the closing of the Proposed Transaction, and performance in all material respects of all obligations, and compliance in all material respects with the agreements and covenants, contained in the Merger Agreement, (2) approval by our shareholders of the Merger Agreement and the transactions contemplated by the Merger Agreement, (3) the absence of any laws or orders by a governmental entity having jurisdiction over any party to the Merger Agreement that make illegal, enjoin, or prohibit consummation of the Merger or the transactions contemplated by the Merger Agreement, and (4) the absence of a Company Material Adverse Effect (as defined in the Merger Agreement) between the date of the Merger Agreement and the closing of the Merger.

Assuming the satisfaction of the conditions set forth in the Merger Agreement, we expect the Merger to close during the quarter ending March 31, 2025. Following the effective time of the Merger, our common stock will be delisted from Nasdaq and deregistered under the Exchange Act.

April 2023 Restructuring and May 2024 Restructuring

product line. Our Board of Directors performed a thorough review of a number of factors including the competitive landscape, declining revenue and gross profit of these discontinued businesses, the current and expected profitability of these discontinued businesses, our cost structure, and our strategic focus on our Inertial Navigation business segment, and concluded that these discontinued businesses were non-strategic, unsustainable, and could not be restructured in a way that would have allowed us to achieve profitable growth and cash preservation. During the quarter ended September 30, 2023, the Broadband business segment and defense optoelectronics product line were considered as held for sale based upon the existence at such time of an executed non-binding letter of intent with respect to the PF Transaction (as defined below) and in consideration of ongoing negotiations for the sale of the chips business. Given the then-prospective sale of the Broadband business segment and defense optoelectronics product line we identified these asset groups as discontinued operations during the quarter ended September 30, 2023. We discontinued operations of our chips business and indium phosphide wafer fabrication facility during the quarter ended September 30, 2023, consummated the PF Transaction during the quarter ended December 31, 2023 and consummated the Chips Transaction (as defined below) on April 30, 2024.

In May 2024, we initiated the May 2024 Restructuring. Our Board of Directors performed a thorough review of a number of factors including our competitive landscape, expected revenue and profitability, and cost structure, and concluded that our then-current structure and operations would not allow us to achieve profitable growth and cash generation. The full closure of the facility in Alhambra, CA (the “Alhambra Facility”) was completed during the quarter ended September 30, 2024 and was not considered a part of our previously identified and reported discontinued operations, as these actions were part of a consolidation and expense reduction program.

Primarily as a result of these restructurings, we (i) eliminated approximately 200 positions across all locations, collectively representing approximately 50% of our total workforce prior to such reductions, and (ii) consolidated facility space by shutting down our operations at the Alhambra Facility (including sublease of three of the five buildings at the Alhambra Facility pursuant to the Chips Transaction and PF Transaction and the additional sublease of another building to other third parties) and seeking to sublease the remaining available space in such facility, transferred our manufacturing support and engineering center in China to PF pursuant to the PF Transaction, and plan to relocate personnel at the Concord Facility to the operations area from the adjacent office building, collectively representing an approximately 35% reduction in the aggregate square footage occupied by our facilities.

The personnel reduction actions that we have taken in connection with the May 2024 Restructuring have resulted in annualized cost savings of approximately $17.0 million, exclusive of severance costs. One-time employee severance and termination costs of approximately $2.9 million were incurred during the fiscal year ended September 30, 2024. During the fiscal year ended September 30, 2024, we also incurred $2.2 million of restructuring expense including $0.9 million in expenses of the Chief Restructuring Officer, which we engaged in June 2024 in connection with the Credit Agreement and the Forbearance Agreement, $0.8 million in impairment of the inventory located at the Alhambra Facility, $0.3 million of impairment of the manufacturing execution system at the Alhambra Facility, and $0.2 million in costs to tear-down, pack and move equipment out of the Alhambra Facility.

Reverse Stock Split

On March 15, 2024, our shareholders approved an amendment to our certificate of incorporation to effect a reverse split of our outstanding common stock at a ratio ranging from 5:1 to 12:1 at the sole discretion of the Board of Directors of the Company. On March 15, 2024, the Board of Directors approved a reverse split and set a reverse stock split ratio of 10:1 for our outstanding shares of common stock. The reverse stock split was effective on April 1, 2024, and began trading on a reverse stock split-adjusted basis on April 2, 2024. As of the effective time of the reverse split, every 10 issued and outstanding shares of our common stock was automatically reclassified into one issued and outstanding share of our common stock, with any fractional shares being rounded up to the next whole share. Proportionate adjustments were made to the number of shares of common stock underlying our outstanding equity awards, warrants, the number of shares issuable under our equity incentive plans and other existing agreements, as well as the exercise or conversion price, as applicable.

Hale Credit Agreement

On August 9, 2022, we and S&N, our wholly-owned subsidiary, entered into that certain Credit Agreement, dated as of August 9, 2022, among the Company, S&N, the lenders party thereto and Wingspire Capital LLC, as administrative agent for the lenders (“Wingspire”), as amended pursuant to that First Amendment to Credit Agreement, dated as of October 25, 2022, among the Company, S&N, EMCORE Chicago, our wholly-owned subsidiary (together with the Company and S&N, the “Borrowers”), the lenders party thereto and Wingspire, to add EMCORE Chicago as a Borrower and include certain of its assets in the borrowing base (as amended, the “Credit Agreement”). The Credit Agreement provided for two credit facilities: (a) an asset-based revolving credit facility in an aggregate principal amount of up to $40.0 million, subject to a borrowing base consisting of eligible accounts receivable and eligible inventory (subject to certain reserves), and (b) a term loan facility in an aggregate principal amount of $5,965,000.

Table of Contents

On April 29, 2024, Wingspire, HCP-FVU, LLC, HCP Fund V-FVU, LLC and Bessel Holdings LLC (each an affiliate of Hale Capital Management, L.P. and collectively, “Hale” or “New Lenders”), and HCP-FVU, LLC, as administrative agent for New Lenders (in such capacity, the “Successor Agent”), entered into an Assignment Agreement (the “Assignment Agreement”) pursuant to which Hale acquired all of Wingspire’s interest in the credit facilities extended by Wingspire to us pursuant to the Credit Agreement and all of the Loan Documents (as defined in the Credit Agreement) and any other documents, instruments, certificates, financing statements and agreements relating to the Credit Agreement. In connection with the Assignment Agreement, we entered into a Forbearance Agreement and Second Amendment to Credit Agreement with S&N and EMCORE Chicago, Hale, and the Successor Agent dated April 29, 2024 (the “Forbearance Agreement”). Under the terms of the Forbearance Agreement, Hale agreed: (i) not to accelerate the obligations or exercise other default remedies under the Credit Agreement and related documents; (ii) not to enforce any of the provisions or terms of the Credit Agreement and the related collateral documents relating to the occurrence of one or more cash dominion trigger events; and (iii) to direct the Successor Agent not to accelerate the obligations, exercise default remedies or take any such enforcement action or enforcement of provisions under the Credit Agreement and related documents during the period (the “Forbearance Period”) beginning on April 29, 2024 through the earliest of: (i) May 31, 2024; (ii) the date that any breach or default occurs or is determined to have occurred under the Credit Agreement or any other related document, including the Forbearance Agreement; and (iii) the date that we initiate any judicial, administrative or arbitration proceeding against Hale or the Successor Agent. The Forbearance Agreement also amended the Credit Agreement to, among other things, set a fixed interest rate of 12% per annum (with an additional 6% upon the occurrence and during the continuance of an event of default, which shall not apply during the Forbearance Period to any of the events of default as to which the forbearance applies) on each loan. The Forbearance Agreement reduced the aggregate principal amount that we could draw under the revolving credit facility from $40.0 million to $4.6 million, subject to a borrowing base consisting of eligible accounts receivable, eligible inventory and eligible equipment (subject to certain reserves). The Forbearance Agreement also provided that we could elect to pay all or a portion of the interest that would accrue under the Credit Agreement as payment-in-kind, which would allow us to increase the principal balance of the loans due and payable upon maturity, rather than making interest payment in cash. In addition, the Forbearance Agreement provided for certain financial covenants, loosened the circumstances under which we would have to comply with a fixed charge coverage ratio, and eliminated all restrictions relating to cash dominion.

On April 29, 2024 (the “Issuance Date”), in consideration of the Forbearance Agreement, we issued to Successor Agent a warrant (the “Warrant”) to purchase an aggregate of 1,810,528 shares of our common stock at an exercise price of $2.73 per share. The Warrant is exercisable, at any time and from time to time, for 10 years following the Issuance Date. Under the terms of the Warrant, we have a right to force Successor Agent to exercise the Warrant under certain Forced Exercise Conditions (as defined in the Warrant) and issue a replacement warrant, and Successor Agent has a right to require us to purchase the unexercised portion of the Warrant under certain circumstances, including upon a Fundamental Transaction (as defined in the Warrant). If we are required to purchase the unexercised portion of the Warrant, we may elect to pay such repurchase price in the form of an unsecured promissory note.

The Warrant provides for certain adjustments to the exercise price and the number of shares issuable upon exercise of the Warrant in certain circumstances, including a full-ratchet anti-dilution adjustment in connection with certain issuances of common stock and convertible securities by us below the then current exercise price of the Warrant. We also agreed to register for resale with the SEC the shares issuable upon exercise of the Warrant. The Warrant contains restrictions on Successor Agent’s ability to exercise the Warrant, such that Successor Agent shall not be entitled to exercise the Warrant if the total number of shares of common stock then beneficially owned by Successor Agent, and its affiliates and any other persons whose beneficial ownership of common stock would be aggregated with Successor Agent’s other ownership of our common stock, exceeds 4.999% of the total number of issued and outstanding shares of our common stock (the “Threshold Percentage”). However, Successor Agent has the right at any time and from time to time, to increase the Threshold Percentage to 9.999%. Additionally, Successor Agent shall not have the right to exercise the Warrant if the total number of shares of common stock then beneficially owned by Successor Agent, and its affiliates and any other persons whose beneficial ownership of common stock would be aggregated with Successor Agent’s other ownership of our common stock, exceeds 19.99%, unless shareholder approval is obtained by us, as may be required by the applicable rules and regulations of Nasdaq or any such other exchange on which our shares are then listed, or unless such shareholder approval requirement has been waived by Nasdaq. Notwithstanding anything to the contrary in the Warrant, the sum of the number of shares of common stock that may be issued under the Warrant is limited to 19.99% of our outstanding shares of common stock as of the issuance date of the Warrant (the “Exchange Cap”), unless shareholder approval is obtained by us to issue more than the Exchange Cap, as may be required by the applicable rules and regulations of Nasdaq or any such other exchange on which our shares are then listed, or unless such shareholder approval requirement has been waived by Nasdaq.

On August 5, 2024, we voluntarily prepaid approximately $9.4 million to repay (with effect as of August 8, 2024) (the “Repayment”) in full all amounts outstanding and payable under the Credit Agreement. In connection with the termination of the Credit Agreement, the total amount repaid by the Company of approximately $9.4 million consisted of approximately $8.5

Table of Contents

million of principal, approximately $0.8 million of accrued interest, including interest that would have accrued through the one-year anniversary of the Forbearance Agreement, approximately $0.1 million of prepayment premium and approximately $0.1 million of customary expenses of the Successor Agent and the Lenders.

As a result of the Repayment, all of the Obligations (as defined in the Credit Agreement) were satisfied in full and the Credit Agreement, the other Loan Documents (as defined in the Credit Agreement) and any other documents, instruments, certificates, financing statements, and agreements related to the Credit Agreement terminated (collectively, the “Financing Documents”). As a result of the termination of the Credit Agreement, the Successor Agent, the Lenders and their respective participants, if any, have no further commitment to provide loans or other financial accommodations under the Credit Agreement or any of the other Loan Documents. We received confirmation (in the form of a customary payoff letter) of such termination from the Successor Agent on behalf of the Lenders.

Divestiture to HieFo Corporation

On April 30, 2024, we entered into an Asset Purchase Agreement (the “HieFo Purchase Agreement”) with HieFo, pursuant to which we agreed to transfer to HieFo substantially all of the assets primarily related to our discontinued chips business line, including with respect to equipment, contracts, intellectual property and inventory, including without limitation our indium phosphide wafer fabrication equipment, in consideration for a purchase price equal to $2.9 million in cash and assumption by HieFo of certain assumed liabilities (collectively, the “Chips Transaction”), $1.0 million of which was received by us in the quarter ended December 31, 2023 in connection with the execution of a non-binding letter of intent related to the Chips Transaction and $1.9 million of which was received by us upon closing of the Chips Transaction. The signing and closing of the Chips Transaction occurred simultaneously.

In connection with the Chips Transaction, we and HieFo entered into a transition services agreement pursuant to which we provided certain migration and transition services to facilitate an orderly transition of the operation of the chips business line to HieFo in consideration for fees payable to us for such services as agreed between us and HieFo for a period of up to 12 months following consummation of the Chips Transaction, and we and HieFo entered into a sublease pursuant to which we are subleasing to HieFo (i) initially, all of one building and a portion of a second building (collectively occupying approximately 21,750 square feet) and (ii) beginning January 1, 2026, all of such two buildings (collectively occupying approximately 25,000 square feet) at the Alhambra Facility through the remaining term of our lease of such facility ending September 30, 2031, with a pro rata portion of the rent for such facility being payable to us beginning on July 1, 2024 (the “HieFo Sublease”).

Divestiture to Photonics Foundries

On October 11, 2023, we entered into an Asset Purchase Agreement, by and among us, PF, and the “Buyer, pursuant to which (i) we agreed to transfer to the Buyer, and Buyer agreed to assume, substantially all of the assets and liabilities primarily related to the Businesses, including with respect to employees, contracts, intellectual property and inventory, and (ii) Buyer agreed to provide a limited license back to us of the patents being sold to the Buyer. The PF Transaction excludes our chip business, indium phosphide wafer fabrication facilities and all assets not primarily related to the Businesses. The signing and closing of the PF Transaction occurred simultaneously, except with respect to our assets located in China. On November 30, 2023, we transferred to the Buyer, and the Buyer assumed, substantially all of the assets and liabilities of each of our subsidiaries in China.

In connection with the PF Transaction, the parties entered into a transition services agreement pursuant to which we are providing certain migration and transition services to facilitate an orderly transition of the operation of the Businesses to the Buyer in the 12-month period following consummation of the PF Transaction, and we and the Buyer entered into a sublease pursuant to which we are subleasing to the Buyer one of our buildings (occupying approximately 12,500 square feet) at the Alhambra Facility: initially, for the 12-month period immediately following the closing of the PF Transaction without payment of rent and, for the period beginning October 12, 2024 and ending March 31, 2025, for rent in an amount approximately equal to the pro rata portion of the rent payable for such portion of the facility by us under our master lease. With respect to the Buyer’s assumption of that certain Manufacturing Supply Agreement, dated August 9, 2021 (as amended, the “Fastrain Manufacturing Agreement”), by and among the Company, Shenzhen Fastrain Technology Co., Ltd., Hong Kong Fastrain Company Limited, and Fastrain Technology Malaysia SDN. BHD (collectively, “Fastrain”), we (i) made a payment to Fastrain in the amount of approximately $0.4 million immediately prior to the closing of the PF Transaction and (ii) provided a guaranty of PF’s and the Buyer’s obligations with respect to payment of certain long-term liabilities that were originally agreed to and set forth in the Fastrain Manufacturing Agreement and assigned to PF and the Buyer in the PF Transaction, in an aggregate amount expected to equal up to approximately $5.5 million, approximately $4.2 million of which will not become payable, if at all, until January 2026, provided that if such guaranty is exercised by Fastrain, we will have the right to require the Buyer to reassign to us all intellectual property assigned to the Buyer in the PF Transaction and we will have the right to recover damages from PF and the Buyer.

Economic Conditions

The increased instability of global economic conditions and inflationary risks are adding to the uncertainty of our business. These adverse conditions could result in longer sales cycles, increased costs to manufacture our products, and increased price competition. Given the dynamic nature of these macroeconomic conditions, we cannot reasonably estimate their full impact on our ongoing business, results of operations, and overall financial performance.

Critical Accounting Estimates

The discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets and liabilities, revenues and expenses, and related disclosure at the date of our financial statements. Critical accounting estimates are those estimates made that involve a significant level of estimation uncertainty and have had or are reasonably likely to have a material impact on our statement of operations and financial position. We develop estimates based on historical experience and on various assumptions about the future that are believed to be reasonable based on the best information available to us. The reported financial position or results of operations may be materially different under changed conditions or when using different estimates and assumptions, particularly with respect to significant accounting policies. In the event that estimates or assumptions prove to differ from actual results, adjustments are made in subsequent periods to reflect more current information.

We have other significant accounting policies that do not generally require subjective estimates or judgments or would not have a material impact on our results of operations. Our significant accounting policies are described in Note 2 – Summary of Significant Accounting Policies.

Inventory Reserves

We write-down inventory once it has been determined that conditions exist that may not allow the inventory to be sold for its intended purpose or the inventory is determined to be excess or obsolete based on assumptions about future demand and market conditions. The charge related to inventory write-downs is recorded as cost of revenue. We evaluate inventory levels at least quarterly against sales forecasts on a significant part-by-part basis, in addition to determining its overall inventory risk. We have incurred, and may in the future incur, charges to write-down inventory. Inventory reserves for the fiscal years ended September 30, 2024 and 2023 was $11.5 million and $10.0 million, respectively. The increase in the reserve of $1.5 million was primarily due to our lower of cost or market analysis and changes in market conditions for certain of our products.

Impairment Estimates of Long-Lived Intangible and Other Assets

We follow the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 360, Property Plant, and Equipment (“ASC 360”). ASC 360 requires review of long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of finite-life intangible assets with estimated useful lives and other long-lived assets (property, plant, and equipment) is measured by a comparison of the carrying amount of an asset or asset group to future net undiscounted cash flows expected to be generated by the asset or asset group. If these comparisons indicate that an asset is not recoverable, we will recognize an impairment loss for the amount by which the carrying value of the asset or asset group exceeds the related estimated fair value. Estimated fair value is based on either discounted future operating cash flows or appraised values, depending on the nature of the asset.

During the fiscal year ended September 30, 2024, the facility consolidation component of the May 2024 Restructuring included the completed closure of the two remaining buildings at the Alhambra Facility that were not part of the 2023 shutdown and discontinuance of the Broadband segment and defense optoelectronics product line. Operating activities related to our current inertial navigation business that were performed in these two remaining buildings were transferred to the Tinley Park Facility. These actions at our Alhambra Facility were an impairment indicator that led us to test long-lived assets on May 1, 2024. Recoverability of the long-lived assets was measured by comparing the carrying value of the asset groups to the future net undiscounted cash flows expected to be generated by the asset groups. The comparison indicated that the carrying value was recoverable and no further impairment to long-lived assets was recorded.

During the fiscal year ended September 30, 2023, for the reporting unit formerly known as Aerospace & Defense, an indication of goodwill impairment (after electing to quantitatively test goodwill) was a trigger to test long-lived assets, and for the discontinued reporting unit formerly known as Broadband, the change in intended use of our leased facilities and right-of-use (ROU) assets due to the restructuring of our business led to reevaluating those retained asset groups. Recoverability of the long-

Table of Contents

lived assets was measured by comparing the carrying amount of the asset groups to the future net undiscounted cash flows expected to be generated by the asset groups. The comparison indicated that certain of the asset groups was not recoverable, and an impairment of $1.4 million was recorded, as this was the amount by which the carrying value of the asset group exceeded the related estimated fair value, which was based on discounted future operating cash flows.

Impairment Assessment for Goodwill and Indefinite Lived Intangible Assets

We follow FASB ASC Topic 350, Intangibles-Goodwill and Other (“ASC 350”). ASC 350 requires the completion of a goodwill impairment test and test of other indefinite lived intangible assets at least annually based on either an optional qualitative assessment (Step 0) or a quantitative analysis (Step 1) comparing the estimated fair value of a reporting unit or indefinite lived intangible asset to its carrying value as of the test date of July 1st each year, unless there are indications requiring a more frequent impairment test. Any impairment charges are based on the quantitative (Step 1) analysis.

The July 1, 2024 indefinite-lived intangible asset test included a certain Company trademark. The quantitative (Step 1) analysis performed over such trademark utilized the relief from royalty method of the income approach to determine the fair value. Per our analysis, it was concluded that the fair value of the trademark exceeded the $0.9 million carrying value of such trademark by greater than 10% and no impairment was recorded.

The July 1, 2023 indefinite-lived intangible asset test included a certain Company trademark as of July 1, 2023. The quantitative (Step 1) analysis performed over such trademark utilized the relief from royalty method of the income approach to determine the fair value. It concluded that the carrying value of such trademark, which was $2.2 million, exceeded the fair value and impairment expense of $1.3 million was recorded. We performed a qualitative (Step 0) analysis over the in-process research and development (IPR&D) at July 1 2023. However, in the quarter ended September 30, 2023, it was determined that the Company would abandon the project underlying the remaining IPR&D and, as a result of this determination, the carrying value of $0.8 million was impaired during the quarter ended September 30, 2023.

The July 1, 2023 quantitative (Step 1) analysis of goodwill utilized a weighted income and market approach concluded that the carrying value of the reporting unit that carried the goodwill, including goodwill (adjusted for trademark impairment) was greater than the fair value of equity of the reporting unit, and impairment expense of $19.0 million was recorded. After this impairment charge, the balance of goodwill at September 30, 2023 was reduced to zero.

Revenue

For the fiscal year ended September 30, 2024, revenue decreased by $11.8 million or 12.1% compared to the prior fiscal year primarily due to a decrease of $18.1 million from operations from the Budd Lake Facility as a result of the termination of the TAIMU program by a customer as well as a slowdown in demand associated with our BoRG program, offset by an increase of $6.1 million from operations at the Concord Facility, driven largely by increased shipments of the SDI500 Quartz MEMS IMU related to the MK48 and MK54 torpedo programs.

Gross Profit

Gross profit is revenue less cost of revenue. Cost of revenue consists of raw materials, compensation expense, depreciation, amortization and accretion expense, and other manufacturing overhead costs, expenses associated with excess and obsolete inventories, and product warranty costs. Historically, gross profit as a percentage of revenue, which we refer to as gross margin, has fluctuated significantly due to revenue and production volumes over fixed manufacturing costs, product mix, manufacturing yields, and inventory charges (e.g., scrap factors, excess and obsolete, inventory valuation adjustments).

For the fiscal year ended September 30, 2024, gross profit decreased by $4.6 million or 19.5% and gross margin decreased from 23.9% to 21.9% compared to the prior fiscal year. The lower fiscal 2024 gross profit was largely due to the TAIMU and BoRG revenue declines from the TAIMU and BoRG programs as well as higher costs related to production yields and excess inventory charges at the Concord Facility.

Selling, General, and Administrative

Selling, general, and administrative (“SG&A”) consists primarily of personnel related expenditures for sales and marketing, IT, finance, legal, and human resources support functions.

For the fiscal year ended September 30, 2024, SG&A decreased by $10.5 million or 31.9% compared to the prior fiscal year primarily driven by compensation expense reduction as a result of headcount reductions described above in “Recent Developments - April 2023 Restructuring and May 2024 Restructuring”.

Research and Development

Table of Contents

Research and development (“R&D”) include personnel related expenditures, project costs, and facility-related expenses. We intend to continue to invest in R&D programs because they are essential to our future growth.

For the fiscal year ended September 30, 2024, R&D expense decreased by $5.0 million or 27.9% compared to the prior fiscal year primarily driven by the headcount reductions described above in “Recent Developments - April 2023 Restructuring and May 2024 Restructuring” which delivered compensation cost savings supported by discretionary cost management savings and a modest increase in costs directly correlated to contract revenue transferred from R&D into Cost of Revenue.

Restructuring

For the fiscal year ended September 30, 2024, restructuring expense totaled approximately $2.2 million associated with $0.9 million in expenses of the Chief Restructuring Officer, which we engaged in June 2024 in connection with the Credit Agreement and the Forbearance Agreement, $0.8 million in impairment of inventory at the Alhambra Facility, $0.3 million of impairment of the manufacturing execution system at the Alhambra Facility, and $0.2 million in costs to tear-down, pack and move equipment out of the Alhambra Facility.

Severance

For the fiscal year ended September 30, 2024, severance totaled approximately $2.9 million. The significant expense in fiscal year ended September 30, 2024 was largely attributable to the completion of the restructuring plan announced on May 23, 2024, which included personnel reductions of approximately 40% of the workforce, including a CEO transition that accounted for $1 million of the severance. Additionally, there were other staff reductions earlier in the fiscal year ended September 30, 2024 that contributed to the higher severance expense. See "Recent Developments - April 2023 Restructuring and May 2024 Restructuring" for discussion on severance expense.

Impairment

For the fiscal year ended September 30, 2024, impairment charge totaled approximately $3.0 million, largely attributable to the full shutdown of the remaining Alhambra Facility that resulted in charges of $2.4 million for leasehold improvements and $0.5 million for ROU assets.

For the fiscal year ended September 30, 2023, impairment charge totaled approximately $22.6 million, largely attributable to a $19.0 million for goodwill, $1.1 million for intangible assets, and $1.4 million for ROU assets related to the abandonment of three buildings at the Alhambra Facility.

Gain on Sale of Assets

For the fiscal year ended September 30, 2023, gain on sale of assets totaled approximately $1.1 million primarily related to the consummation of the sale of the real property interests in the Tinley Park Facility.

Loss on Extinguishment of Debt and Change in Fair Value of Warrant Liability

During the fiscal year ended September 30, 2024, in consideration of the Forbearance Agreement, the Company issued the Warrant to the Successor Agent to purchase an aggregate of 1,810,528 (post-reverse split) shares of the Company’s common stock at an exercise price of $2.73 per share. The Warrant is exercisable, at any time and from time to time, for 10 years following the Issuance Date. The Company has and will continue to subsequently remeasure the fair value of the Warrant each reporting period as long as the Warrant remains classified as a liability with changes in the fair value reported in the caption “Loss on extinguishment of debt and change in fair value of warrant liability” on the consolidated statements of operations and comprehensive loss. We believe that the assumptions used in the calculations of fair value of the warrant liability represent the best estimates of fair value. As of September 30, 2024, using the Monte Carlo simulation valuation method, the fair value of the Warrant using Level 3 inputs was recorded as a $4.7 million non-current liability in the consolidated balance sheet and for the fiscal year ended September 30, 2024 the corresponding net expense of $2.6 million and $4.7 million is included in “Loss on extinguishment of debt and change in fair value of warrant liability” in the consolidated statements of operations and comprehensive loss.

Interest Expense, net

For the fiscal year ended September 30, 2024, interest expense, net was approximately $1.2 million primarily related to us voluntarily prepaying in full all amounts outstanding and payable in connection with the termination of the Credit Agreement. The total amount repaid by the Company of approximately $9.4 million consisted of approximately $0.8 million of accrued

Table of Contents

interest, including interest that would have accrued through the one-year anniversary of the Forbearance Agreement, approximately $0.1 million of prepayment premium and approximately $0.1 million of customary expenses of the Successor Agent and the New Lenders.

Other Income

For the fiscal year ended September 30, 2024, other income totaled approximately $3.6 million primarily related to (i) an adjustment in ARO of $2.1 million in connection with the HieFo Sublease, pursuant to which Hiefo assumed end-of-lease remediation liabilities with respect to certain buildings at the Alhambra Facility and (ii) $1.7 million as a result of a negotiated business settlement related to the acquisition of S&N.

Liquidity and Capital Resources

We have recently experienced significant losses from our operations and used a significant amount of cash in connection with strategic acquisitions to further our strategy of focusing on our Inertial Navigation business. As a result of our recent operating cash shortage, we have taken actions to manage our liquidity and will need to continue to manage our liquidity as we continue to restructure our operations to focus on our Inertial Navigation business. In addition, on November 7, 2024, we entered into the Merger Agreement with Parent, Parent Group Member, and Merger Sub – see “Aerosphere Power Merger Agreement” in “Recent Developments” above for additional information related to the Merger Agreement. As of September 30, 2024, cash and cash equivalents totaled $10.8 million and net working capital totaled $36.6 million. Net working capital, calculated as current assets (including inventory) minus current liabilities, is a financial metric we use which represents available operating liquidity.

We have taken a number of actions to continue to support our operations and meet our obligations:

•In April 2023, we initiated a restructuring program that included the strategic shutdown of our Broadband business segment (including our cable TV, wireless, sensing and chips product lines) and the discontinuance of our defense optoelectronics product line. Our Board of Directors performed a thorough review of a number of factors including the competitive landscape, declining revenue and gross profit of these discontinued businesses, the current and expected profitability of these discontinued businesses, our cost structure, and our strategic focus on our Inertial Navigation business segment, and concluded that these discontinued businesses were non-strategic, unsustainable, and could not be restructured in a way that would have allowed us to achieve profitable growth and cash preservation. During the quarter ended September 30, 2023, the Broadband business segment and defense optoelectronics product line were considered as held for sale based upon the existence at such time of an executed non-binding letter of intent with respect to the PF Transaction and in consideration of ongoing negotiations for the sale of the chips business. Given the then-prospective sale of the Broadband business segment and defense optoelectronics product line, we identified these asset groups as discontinued operations during the quarter ended September 30, 2023. We discontinued operations of our chips business and indium phosphide wafer fabrication facility during the quarter ended September 30, 2023, consummated the PF Transaction during the three months ended December 31, 2023 and consummated the Chips Transaction on April 30, 2024. In May 2024, we initiated the May 2024 Restructuring. Our Board of Directors performed a thorough review of a number of factors including our competitive landscape, expected revenue and profitability, and cost structure, and concluded that our then-current structure and operations would not allow us to achieve profitable growth and cash generation. The full closure of the Alhambra Facility was completed during the quarter ending September 30, 2024. Primarily as a result of these restructurings, we (i) eliminated approximately 200 positions across all locations, collectively representing approximately 50% of our total workforce prior to such reductions, and (ii) consolidated facility space by shutting down our operations at the Alhambra Facility (including sublease of three of the five buildings at the Alhambra Facility pursuant to the Chips Transaction and PF Transaction and the additional sublease of another building to other third parties) and seeking to sublease the remaining available space in such facility, transferred our manufacturing support and engineering center in China to PF pursuant to the PF Transaction, and plan to relocate personnel at the Concord Facility to the operations area from the adjacent office building, collectively representing an approximately 35% reduction in the aggregate square footage occupied by our facilities. The personnel reduction actions that we have taken in connection with the May 2024 Restructuring have resulted in annualized cost savings of approximately $17.0 million, exclusive of severance costs. One-time employee severance and termination costs related to the May 2024 Restructuring of approximately $2.9 million were incurred during the fiscal year ended September 30, 2024. During the fiscal year ended September 30, 2024, we also incurred $2.2 million of restructuring expense including $0.9 million in expenses of the Chief Restructuring Officer, which we engaged in June 2024 in connection with the Credit Agreement and the Forbearance Agreement,$0.8 million in impairment of inventory at the Alhambra Facility, $0.3 million of impairment of the manufacturing execution system at the Alhambra Facility, and $0.2 million in costs to tear-down, pack and move equipment out of the Alhambra Facility.

•On April 30, 2024, we entered into the HieFo Purchase Agreement with HieFo, with respect to the Chips Transaction for a purchase price equal to $2.9 million in cash and assumption by HieFo of certain assumed liabilities, $1.0 million of which was received by us in the quarter ended December 31, 2023 and $1.9 million of which was received by us

Table of Contents

upon closing of the Chips Transaction on April 29, 2024. We and HieFo also entered into a transition services agreement pursuant to which we provided certain migration and transition services to facilitate an orderly transition of the operation of the chips business line to HieFo in consideration for fees payable to us for such services as agreed between us and HieFo for a period of up to 12 months following consummation of the Chips Transaction, and we and HieFo entered into a sublease pursuant to which we are subleasing to HieFo (i) initially, all of one building and a portion of a second building (collectively occupying approximately 21,750 square feet) and (ii) beginning January 1, 2026, all of such two buildings (collectively occupying approximately 25,000 square feet) at the Alhambra Facility through the remaining term of our lease of such facility ending September 30, 2031, with a pro rata portion of the rent for such facility being payable to us beginning on July 1, 2024.

•In August 2023, we closed our offering of 2,260,000 shares of our common stock at a price of $5.00 per share, and, to certain investors, pre-funded warrants to purchase 1,190,000 shares of our common stock at a price of $4.9999999 for each pre-funded warrant (which represents the per share public offering price for our common stock in such offering less the $0.0000001 per share exercise price for each such pre-funded warrant), resulting in net proceeds to us from the offering, after deducting the placement agent commissions and other offering expenses, of approximately $15.6 million.

•In February 2023, we closed our offering of 1,545,455 shares of our common stock at a price of $11.00 per share, resulting in net proceeds to us from the offering of $15.4 million.

Our existing balances of cash and cash equivalents, cash flows from operations, together with additional actions we may take to further reduce our expenses and/or additional funds we may receive if we elect to raise capital through additional debt or equity issuances or from our efforts to monetize certain assets, are anticipated to provide us with sufficient financial resources to meet cash requirements for operations, working capital, and capital expenditures for at least the next 12 months from the issuance date of the September 30, 2024 consolidated financial statements. However, we may not be successful in executing on our plans to manage our liquidity, including recognizing the expected benefits from our restructuring described above or raising additional financing, and our ability to continue to operate as a going concern could be impaired, which could in turn cause a significant decline in our stock price and could result in a significant loss of value for our shareholders. Accordingly, substantial doubt about our ability to continue as a going concern exists. The accompanying consolidated financial statements have been prepared on a going concern basis, as the going concern assumption contemplates the realization of assets and satisfaction of liabilities in the normal course of business.

We continue to explore a range of options to further address our capitalization and liquidity, and on November 7, 2024, we entered into the Merger Agreement with Parent, Parent Group Member, and Merger Sub – see “Aerosphere Power Merger Agreement” in “Recent Developments” above for additional information related to the Merger Agreement. If we raise funds by issuing debt securities or incurring loans, this form of financing would have rights, preferences, and privileges senior to those of holders of our common stock. The availability and the terms under which we can borrow additional capital could be disadvantageous, and the terms of debt securities or borrowings could impose significant restrictions on our operations. Macroeconomic conditions and credit markets could also impact the availability and cost of potential future debt financing. If we raise capital through the issuance of additional equity, such sales and issuance would dilute the ownership interests of the existing holders of our common stock. There can be no assurances that any additional debt or equity financing would be available to us or if available, that such financing would be on favorable terms to us. In addition, if adequate funds are not available to fund our future operations, we may need to curb our business plans, which could have a material adverse impact on our business prospects and results of operations.

Operating Activities

For the fiscal year ended September 30, 2024, operating activities for continuing operations used cash of $5.5 million, primarily due to net loss from continuing operations of $26.9 million offset by adjustments for non-cash charges, including depreciation, amortization, and accretion expense of $5.5 million, impairment of long-lived asset charges of $3.0 million, and losses on extinguishment of debt and changes in fair value of warrant liability of $4.7 million and further offset by $9.4 million in changes in operating assets and liabilities. The change in operating assets and liabilities was primarily the result of a decrease in contract assets of $7.2 million predominantly due to a favorable modification in the billing schedule of a large customer contract, a decrease in inventory of $3.8 million due to higher shipments from the Concord Facility, a decrease in accounts receivable of $1.1 million due to lower revenue, and a decrease in other assets of $1.9 million due to a decrease in prepaid

Table of Contents

expenses offset by a decrease in accrued expenses and other current liabilities of $3.4 million driven by lowered accrued compensation related to reduction in headcount and a decrease in accounts payable of $1.1 million due to strict monitoring of expenditures.

For the fiscal year ended September 30, 2023, operating activities used cash of $30.3 million, primarily due to net loss from continuing operations of $49.4 million and adjustments for non-cash charges, including depreciation, amortization, and accretion expense of $4.8 million, stock-based compensation expense of $5.4 million, an impairment charge of $22.6 million offset by a revision in the estimate of ARO of $2.1 million and a gain on disposal of assets of $1.1 million. The change in operating assets and liabilities was primarily the result of an increase in accounts receivable of $1.9 million, an increase in customer deposits of $3.7 million, and a decrease in accounts payable of $0.5 million, offset by a decrease in contract assets of $4.6 million, a decrease in inventory of $6.0 million, a decrease in other assets of $3.2 million, an increase in ROU liability of $0.9 million, and an increase in accrued expenses and other current liabilities of $0.3 million.

We used cash from operating activities for continuing operations of approximately $5.5 million in the fiscal year ended September 30, 2024 and anticipate that, for the fiscal year ending September 30, 2025, our operating activities for continuing operations may provide approximately $1.0 million to $2.5 million. The cash we use in, or that is provided by, our operating activities can vary significantly due to a variety of factors, including changes in revenue, inventory, cost of materials, professional fees (including those associated with strategic activities), expenses related to additional restructuring activities that we may decide to implement in the future, and other factors.

Investing Activities

For the fiscal year ended September 30, 2024, investing activities provided cash of $31.0 thousand, primarily due to the sale of property, plant and equipment.

For the fiscal year ended September 30, 2023, investing activities provided cash of $9.2 million, primarily due to $10.9 million in proceeds from the disposal of property, plant and equipment.

For the fiscal year ending September 30, 2025 our investing activities are expected to use cash of $1.3 million.

Financing Activities

For the fiscal year ended September 30, 2024, financing activities used cash of $10.6 million, primarily due to the repayment of our credit facilities.

For the fiscal year ended September 30, 2023, financing activities provided cash of $24.4 million, primarily due to proceeds from sale of common stock, net of issuance costs, of $31.0 million, offset by payments to our line of credit of $6.9 million

Total contractual obligations and commitments	$	55,200	$	16,773	$	9,420	$	3,936	$	25,071

Interest payments are not included in the contractual obligations and commitments table above since they are insignificant to consolidated cash flows of the Company.

Purchase Obligations

Purchase obligations represent an estimate of all open purchase orders and contractual obligations in the ordinary course of business for which we have not received the goods or services as of September 30, 2024. Although open purchase orders are

Table of Contents

considered enforceable and legally binding, the terms generally allow us the option to cancel, reschedule, and adjust requirements based on business needs prior to the delivery of goods or performance of services. The purchase obligations of $12.5 million as of September 30, 2024, set forth above primarily relates to open purchase orders to our component suppliers, service partners, and other vendors.

Asset Retirement Obligations

We have known conditional Asset Retirement Obligation (“ARO”) conditions, such as certain asset decommissioning and restoration of rented facilities to be performed in the future. ARO includes assumptions related to renewal option periods where we expect to extend facility lease terms. Revisions in estimated liabilities can result from revisions of estimated inflation rates, escalating retirement costs, and changes in the estimated timing and obliged party of settling the ARO. See Note 12 - Commitments and Contingencies in the Notes to Consolidated Financial Statements for additional information related to ARO.

Operating Lease Obligations

Operating leases include non-cancelable terms and exclude renewal option periods, property taxes, insurance, and maintenance expenses on leased properties. See Note 12 - Commitments and Contingencies in the Notes to Consolidated Financial Statements for additional information related to operating lease obligations.

Pension Obligations

Future pension obligation payments are subject to revaluation and are dependent on pension fund asset performance and pension obligation valuation assumptions. See Note 8 – Benefit Plans in the Notes to Consolidated Financial Statements for additional information related to pension obligations.

Off-Balance Sheet Arrangements

EMS Guarantee

In addition to the operating leases as reported in our Annual Report on Form 10-K for the fiscal year ended September 30, 2023, in connection with the PF Transaction, with respect to the Buyer’s assumption of that certain Fastrain Manufacturing Agreement, dated August 9, 2021 (as amended, the “Fastrain Manufacturing Agreement”), by and among the Company, Shenzhen Fastrain Technology Co., Ltd., Hong Kong Fastrain Company Limited, and Fastrain Technology Malaysia SDN, we provided a guaranty of PF’s and the Buyer’s obligations with respect to payment of certain long-term liabilities that were originally agreed to and set forth in the Fastrain Manufacturing Agreement and assigned to PF and the Buyer in the PF Transaction, in an aggregate amount expected to equal up to approximately $5.5 million, approximately $4.2 million of which will not become payable, if at all, until January 2026, provided that if such guaranty is exercised by the EMS provider, we will have the right to require the Buyer to reassign to us all intellectual property assigned to the Buyer in the PF Transaction and we will have the right to recover damages from PF and the Buyer.

EMCORE CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Years Ended September 30, 2024 and 2023

NOTE 1. Description of Business

We are a leading provider of sensors and navigation systems for the aerospace and defense market. We leverage

industry-leading Photonic Integrated Chip (“PIC”) and Quartz Micro Electro-Mechanical System (“QMEMS”) chip-level

technology to deliver state-of-the-art component and system-level products across our end-market applications. Over the last six years, EMCORE has expanded its scope and portfolio of inertial sensor products through the acquisitions of Systron Donner Inertial, Inc. (“SDI”) in June 2019, the Space and Navigation (“S&N”) business of L3Harris Technologies, Inc. in April 2022, and the Fiber Optic Gyroscope (“FOG”) and Inertial Navigation Systems business (“EMCORE Chicago”) of KVH Industries, Inc. in August 2022. Our multi-year transition from a broadband company to an inertial navigation company has now been completed following the sales of (i) our cable TV, wireless, sensing and defense optoelectronics business lines in October 2023 and (ii) our chips product line and indium phosphide wafer fabrication operations in April 2024.

NOTE 2. Summary of Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and include the assets, liabilities, shareholders’ equity, and operating results of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The Company is not the primary beneficiary of, nor do we hold a significant variable interest in, any variable interest entity.

Discontinued Operations

In April 2023, we initiated a restructuring program that included the strategic shutdown of our Broadband business segment (including our cable TV, wireless, sensing and chips product lines) and the discontinuance of our defense optoelectronics product line. During the quarter ended September 30, 2023, the Broadband business segment and defense optoelectronics product line were considered as held for sale based upon (i) the existence of an executed non-binding letter of intent to sell our Broadband business segment (other than our chips product line) and our defense optoelectronics product line and (ii) in consideration of ongoing negotiations for the sale of the chips business. Given the prospective sale of the Broadband business segment and defense optoelectronics product line, we identified these asset groups as discontinued operations during the quarter ended September 30, 2023. We ceased operations of our chips business and indium phosphide wafer fabrication facility during the quarter ended September 30, 2023. In accordance with the authoritative guidance for discontinued operations (Accounting Standards Codification (“ASC”) 205-20), the Company determined that these business lines met held-for sale and discontinued operations accounting criteria during the quarter ended September 30, 2023. Accordingly, the Company classified the results of these business lines as discontinued operations in its consolidated statements of operations and comprehensive loss for all periods presented. Additionally, the related assets and liabilities associated with these business lines were classified as held for sale in the September 30, 2023 consolidated balance sheet. See Note 17— Discontinued Operations for additional information.

In October 2023, the Company entered into an Asset Purchase Agreement with Photonics Foundries, Inc., a Delaware corporation (“PF”) and Ortel LLC, a Delaware limited liability company and wholly-owned subsidiary of PF (the “Buyer”), and consummated a transaction pursuant to which (i) the Company transferred to the Buyer, and Buyer assumed, substantially all of the assets and liabilities primarily related to the Company’s TV, wireless, sensing and defense optoelectronics business lines (the “Businesses”), including with respect to employees, contracts, intellectual property and inventory, and (ii) Buyer provided a limited license back to the Company of the patents being sold to the Buyer (the “PF Transaction”). Also in October 2023, the Company entered into a non-binding letter of intent with Asia-Pacific Environment Investment Limited (“APEI”) to sell substantially all of the assets and liabilities related to the Company’s chips business, including assets related to the Company’s

Table of Contents

indium phosphide wafer fabrication operations. On April 30, 2024, the Company entered into an Asset Purchase Agreement (the “HieFo Purchase Agreement”) with HieFo Corporation, a Delaware corporation and affiliate of APEI (“HieFo”), pursuant to which the Company transferred to HieFo substantially all of the assets primarily related to the Company’s discontinued chips business line, including with respect to equipment, contracts, intellectual property and inventory, including without limitation the Company’s indium phosphide wafer fabrication equipment, in consideration for a purchase price equal to $2.9 million in cash and assumption by HieFo of certain assumed liabilities (collectively, the “Chips Transaction”).

Going Concern Basis

We have recently experienced significant losses from operations and used a significant amount of cash, amounting to a net loss of $31.2 million and net cash outflows from operations of $5.5 million for the fiscal year ended September 30, 2024, and we expect to continue to incur losses and use cash in our operations. As a result of our recent cash outflows, we have taken actions to manage our liquidity and will need to continue to manage our liquidity. As of September 30, 2024, our cash and cash equivalents totaled $11 million.

We are evaluating the sufficiency of our existing balances of cash and cash equivalents, cash flows from continuing operations, together with additional actions we could take to further reduce our expenses and/or potentially raising capital through additional debt or equity issuances, or from the potential monetization of certain assets. In addition, on November 7, 2024, we entered into the Merger Agreement with Parent, Parent Group Member, and Merger Sub – see “Aerosphere Power Merger Agreement” in “Note 18 – Subsequent Events” below for additional information related to the Merger Agreement. However, we may not be successful in executing on our plans to manage our liquidity, including recognizing the expected benefits from our previously announced restructuring program, or raising additional funds if we elect to do so, and as a result substantial doubt about our ability to continue as a going concern exists.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities, as of the date of the financial statements, and the reported amounts of revenue and expenses during the reported period. Such estimates include accounts receivable, inventories, long-lived assets, product warranty liabilities, legal contingencies, income taxes, asset retirement obligations, and pension obligation, as well as the evaluation associated with the going concern determination.

We develop estimates based on historical experience and on various assumptions about the future that are believed to be reasonable based on the best information available to us. Our reported financial position or results of operations may be materially different under changed conditions or when using different estimates and assumptions, particularly with respect to significant accounting policies. In the event that estimates or assumptions prove to differ from actual results, adjustments are made in subsequent periods to reflect more current information.

Concentration of Credit Risk

Financial instruments that may subject us to concentrations of credit risk consist primarily of accounts receivable. When necessary, we perform credit evaluations on customers’ financial condition and occasionally we request deposits in advance of shipping product to customers. These financial evaluations require significant judgment and are based on a variety of factors including, but not limited to, current economic trends, historical payment patterns, bad debt write-off experience, and financial review of the particular customer.

Cash and Cash Equivalents

Cash and cash equivalents consists primarily of bank deposits and highly liquid short-term investments with a maturity of three months or less at the time of purchase.

Accounts Receivable

We regularly evaluate the collectability of accounts receivable and maintain allowances for doubtful accounts for estimated losses resulting from the inability of customers to meet their financial obligations to us. The allowance is based on the age of

Table of Contents

receivables and a specific identification of receivables considered at risk of collection. We classify charges associated with the allowance for doubtful accounts as selling, general, and administrative expense.

Inventory

Inventory is stated at the lower of cost or net realizable value (first-in, first-out). Inventory that is expected to be used within the next 12 months is classified as current inventory. We write-down inventory once it has been determined that conditions exist that may not allow the inventory to be sold for its intended purpose or the inventory is determined to be excess or obsolete based on assumptions about future demand and market conditions. The charge related to inventory write-downs is recorded as cost of revenue. We evaluate inventory levels at least quarterly against an estimate of future demand on a significant part-by-part basis, in addition to determining its overall inventory risk. We have incurred, and may in the future incur, charges to write-down of inventory. The allowance for excess and obsolete inventory for the fiscal years ended September 30, 2024 and 2023 was $11.5 million and $10.0 million, respectively. See Note 5 - Inventory for additional information.

Property, Plant, and Equipment

Property, plant, and equipment are recorded at cost. Plant and equipment are depreciated on a straight-line basis over the estimated useful lives of the assets. We depreciate equipment over three to seven years, furniture and fixtures over five years, computer hardware and software over three to five years. Leasehold improvements are amortized over the lesser of the asset life or the lease term. Expenditures for repairs and maintenance are charged to expense as incurred. The costs for major renewals and improvements are capitalized and depreciated over their estimated useful lives of the related asset. The cost and related accumulated depreciation of the assets are removed from the accounts upon disposition and any resulting gain or loss is reflected in the consolidated statement of operations and comprehensive loss. See Note 6 - Property, Plant, and Equipment, net for additional information.

Goodwill and Intangible Assets

Intangible assets of the Company that are considered to have an indefinite life include goodwill and a certain Company trademark. Goodwill represents the excess of the purchase price in a business combination over the fair value of the net tangible and intangible assets acquired. We follow the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 350, Intangibles-Goodwill and Other (“ASC 350”). ASC 350 requires the completion of a goodwill impairment test and test of other indefinite lived intangible assets at least annually based on either an optional qualitative assessment (Step 0) or a quantitative analysis (Step 1) comparing the estimated fair value of a reporting unit or indefinite lived intangible asset to its carrying value as of the test date which is July 1st for the Company. See Note 7 - Intangible Assets and Goodwill for discussion on the impairment of all goodwill in the fiscal year ended September 30, 2023.

Valuation of Long-lived Assets

Long-lived assets consist primarily of finite-life intangible assets, net and property, plant, and equipment, net. Since long-lived assets are subject to amortization and depreciation/amortization, we review these assets for impairment in accordance with the provisions of ASC 360, Property, Plant, and Equipment. Intangible assets that are not considered to have an indefinite useful life are itemized in Note 7 - Intangible Assets and Goodwill and are amortized over their useful lives. We review long-lived assets for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. Impairment testing of long-lived assets consists of determining whether the carrying amount of the long-lived asset or asset group is recoverable, in other words, whether the sum of the future undiscounted cash flows expected to result from the use and eventual disposition of the asset or asset group exceeds the carrying amount. The determination of the existence of impairment involves judgments that are subjective in nature and may require the use of estimates in forecasting future results and cash flows related to an asset or group of assets. In making this determination, we use certain assumptions, including estimates of future cash flows expected to be generated by these assets, which are based on additional assumptions such as asset utilization, the length of service that assets will be used in operations, and estimated salvage values.

Leases

The Company determines if an arrangement is a lease at its inception. Right-of-use (“ROU”) assets and operating lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The Company uses its estimated incremental borrowing rate in determining the present value of lease payments considering the term of the lease, which is derived from information available at the lease commencement date. The lease term includes renewal options when it is reasonably certain that the option will be exercised, and excludes termination options. To the extent that the

Table of Contents

Company’s agreements have variable lease payments, the Company includes variable lease payments that depend on an index or a rate and excludes those that depend on facts or circumstances occurring after the commencement date, other than the passage of time. Lease expense for these leases is recognized on a straight-line basis over the lease term. The Company has elected not to recognize ROU assets and lease liabilities that arise from short-term (12 months or less) leases for any class of underlying asset. Operating leases are included in operating lease ROU assets, current operating lease liabilities, and non-current operating lease liabilities in the Company’s consolidated balance sheets. See Note 12 - Commitments and Contingencies for additional information.

Asset Retirement and Environmental Obligations

Pursuant to ASC 410, Asset Retirement and Environmental Obligations (“ARO”), an ARO is recorded when there is a legal obligation associated with the retirement of a tangible long-lived asset and the fair value of the liability can reasonably be estimated. Upon initial recognition of an ARO, a company increases the carrying amount of the long-lived asset by the same amount as the liability. Over time, the liabilities are accreted for the change in their present value through charges to operations costs. The initial capitalized costs are depleted over the useful lives of the related assets through charges to depreciation, and/or amortization. If the fair value of the estimated ARO changes, an adjustment is recorded to both the ARO and the asset retirement cost. Revisions in estimated liabilities can result from revisions of estimated inflation rates, escalating retirement costs, and changes in the estimated timing of settling ARO liabilities. See Note 12 - Commitments and Contingencies for additional information.

Pension Plan

With the acquisition of S&N, we acquired the assets and assumed the liabilities associated with a pension plan, now named the EMCORE Space & Navigation Corporation Pension Plan (the “Pension Plan”), which is a defined benefit pension plan providing postretirement benefits to certain employees. As of July 1, 2022, the Pension Plan was amended to freeze benefit plan accruals for participants.

The investments in the Pension Plan are measured at fair value using quoted market prices or the net asset value per share as a practical expedient. The projected benefit obligations associated with the Pension Plan are determined based on actuarial models utilizing mortality tables and discount rates applied to the expected benefit term. See Note 8 - Benefit Plans for additional information.

Fair Value of Financial Instruments

We determine the fair value of financial instruments in accordance with ASC 820, Fair Value Measurements and Disclosures. ASC Topic 820 (“ASC 820”), Fair Value Measurements, establishes a valuation hierarchy for disclosure of the inputs to valuation techniques used to measure fair value. This standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value:

•Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities.

•Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the assets or liabilities, either directly or indirectly, through market corroboration, for substantially the full term of the financial instrument.

•Level 3 inputs are unobservable inputs based on assumptions used to measure assets or liabilities at fair value.

Classification of an asset or liability within this hierarchy is determined based on the lowest level input that is significant to the fair value measurement. Valuation techniques used to measure fair value under ASC 820 must maximize the use of observable inputs and minimize the use of unobservable inputs.

Cash and cash equivalents consist primarily of bank deposits or highly liquid short-term investments with a maturity of three months or less at the time of purchase. Restricted cash represents cash temporarily reserved by the Company. Cash, cash equivalents, and restricted cash are based on Level 1 measurements. The carrying amounts of cash and cash equivalents, restricted cash, accounts receivable, contract assets, prepaid expenses, other current assets, accounts payable, accrued expenses and other current liabilities, and contract liabilities approximate fair value because of the short maturity of these instruments.

The Company values its outstanding Warrant (as defined in Note 10 - Credit Agre ement below), which is classified as a liability, using the Monte Carlo Simulation for option pricing, a Level 3 fair value measurement with the assistance of a third-party valuation specialist. The significant unobservable inputs used by the specialists include, in each case of September 30,

Table of Contents

2024, the expected volatility of 72.55% (based on historical daily stock price returns over a look-back period equal to the simulation term), a risk-free rate of 3.75%, a stock price of $2.21, a strike price of $2.73, an expected term of 9.58 years, a dividend yield of 0.00%, and an annual growth rate of 3.00% in shares outstanding. Changes in these inputs could result in materially different fair value measurements. Furthermore, the specialist assumed that the forced exercise provision will be enacted in all possible circumstances, that there could be replacement warrants granted on four separate dates with four unique strike prices, and that the probability of the put right being exercised is de minimis. The Company has and will continue to subsequently remeasure the fair value of the Warrant each reporting period as long as the Warrant remains classified as a liability, with changes in the fair value reported in loss on extinguishment of debt and change in fair value of warrant liability on the consolidated statements of operations and comprehensive loss. See Note 10 - Credit Agreement for the value of the Warrant calculated upon Issuance Date of April 29, 2024 and as of September 30, 2024.

Revenue Recognition

To determine the proper revenue recognition, we perform the following five steps: (a) identify the contract(s) with a customer; (b) identify the performance obligations in the contract; (c) determine the transaction price; (d) allocate the transaction price to the performance obligations in the contract; and (e) recognize revenue when (or as) we satisfy a performance obligation. We only apply the five step model to contracts when it is probable that we will collect the consideration we are entitled to in exchange for the goods or services we transfer to the customer.

The majority of revenues are from product sales to customers pursuant to purchase orders. Revenues from product sales are recognized when the customer obtains control of our product, which occurs at a point in time. The Company has elected to account for shipping and handling activities as a fulfillment cost as permitted by the standard. When we perform shipping and handling activities after the transfer of control to the customer (e.g., when control transfers prior to delivery), they are considered fulfillment activities, and accordingly, the costs are accrued when the related revenue is recognized. We expense incremental costs of obtaining a contract as and when incurred if the expected amortization period of the asset that we would have recognized is one year or less.

We also enter into non-recurring engineering contracts. We recognize revenue for these arrangements over time or at a point in time depending on our evaluation of when the customer obtains control of the promised goods or services. For contracts that include multiple performance obligations, we allocate revenue to each performance obligation based on estimates of the relative standalone selling price that we would charge the customer for each promised product or service.

In addition, we follow the percentage of completion method of revenue recognition for contracts typically for products specific to the customer and for which there is no alternative use for the product. We recognize revenue progressively as the customer takes control of the manufactured products built to customer specifications. Under these manufacturing contracts with customers, the customer controls all of the work-in-progress as products are being built.

We use a number of wholesale distributors around the world and recognize revenue when the wholesale distributor obtains control of our product, which occurs at a point in time, typically upon shipment. Wholesale distributors are contractually obligated to pay us on standard commercial terms, consistent with our end-use customers. We do not sell to wholesale distributors on consignment and do not give wholesale distributors a right-of-return.

Accounts Receivable, Net

Accounts receivable, net, include amounts billed and currently due from customers. The amounts due are stated at their net estimated realizable value. Payments are generally due within 90 days or less of invoicing and do not include a significant financing component. We maintain an allowance for credit loss to provide for the estimated amount of receivables that will not be collected. The allowance is based upon an assessment of customer creditworthiness, historical payment experience, the age of outstanding receivables, and collateral to the extent applicable.

Contract Assets

A contract asset is recognized when the Company has recognized revenue, but has not issued an invoice for payment. Contract assets are classified as current assets and transferred to receivables when the entitlement to payment becomes unconditional. The Company’s contract assets are generally converted to account receivables within 90 days, at which time the Company is entitled to payment of the fixed price upon delivery of the finished product subject to customer payment terms.

Contract Liabilities

Table of Contents

A contract liability is recognized when the Company has billed and received payment from a customer, but has not yet earned revenue. Contract liabilities are classified as current liabilities and transferred to revenue when revenue recognition standards have been met.

Remaining Performance Obligations

Remaining performance obligations represent the transaction price of firm orders for long-term contracts for which control has not transferred to the customer. As of September 30, 2024, the aggregate amount of the transaction price allocated to remaining performance obligations was $11.2 million. The Company expects to recognize revenue on the remaining performance obligations by the end of fiscal year 2025.

Product Warranty Reserves

We provide customers with warranty claims for certain products and warranty-related services are not considered a separate performance obligation. Pursuant to ASC 450, Contingencies, we make estimates of product warranty expense using historical experience rates and accrue estimated warranty expense as a cost of revenue. We estimate the costs of warranty obligations based on historical experience of known product failure rates and anticipated rates of warranty claims, use of materials to repair or replace defective products, and service delivery costs incurred in correcting the product issues. In addition, from time to time, specific warranty accruals may be made if unforeseen technical problems arise.

Disaggregation of Revenue

For additional information on the disaggregated revenues by geographical region and major product category, see Note 14 – Revenue Information.

Income Taxes

In accordance with the authoritative guidance on accounting for income taxes, we recognize income taxes using an asset and liability approach. This approach requires the recognition of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in the consolidated financial statements or tax returns. The measurement of current and deferred taxes is based on provisions of the enacted tax law. The effects of future changes in tax laws or rates are not anticipated.

The authoritative guidance provides for recognition of deferred tax assets if the realization of such deferred tax assets is more likely than not to occur based on an evaluation of all available evidence, both positive and negative, and the relative weight of the evidence. We have determined that at this time it is more likely than not that deferred tax assets attributable to all other items will not be realized, primarily due to uncertainties related to the ability to utilize net operating loss carryforwards before they expire. Accordingly, we have established a valuation allowance for such deferred tax assets which we do not expect to realize. If there is a change in the ability to realize deferred tax assets for which a valuation allowance has been established, then the tax valuation allowance may decrease in the period in which we determine that realization is more likely than not. Likewise, if we determine that it is not more likely than not that deferred tax assets will be realized, then a valuation allowance may be established for such deferred tax assets and the tax provision may increase in the period in which we make the determination. See Note 11 - Income and Other Taxes for additional information.

Recent Accounting Pronouncements

Recently Adopted Accounting Pronouncements

There were no recently adopted accounting pronouncements.

Recent Accounting Standards or Updates Not Yet Effective

In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures, a final standard on improvements to income tax disclosures. The standard requires disaggregated information about a reporting entity's effective tax rate reconciliation as well as information on income taxes paid. The standard is intended to benefit investors by providing more detailed income tax disclosures that would be useful in making capital allocation decisions and applies to all entities subject to income taxes. The new standard is effective for annual periods beginning after December 15, 2024. This accounting

Table of Contents

standard is effective in the first quarter of the Company's fiscal year ended September 30, 2026. The Company does not expect the adoption of this new guidance to have a material impact on the consolidated financial statements.

In November 2023, the FASB issued ASU 2023-07, Improvements to Reportable Segment Disclosures, which enhanced the segment reporting requirements by introducing additional disclosure obligations, including significant segment expenses. The new standard is effective for annual periods beginning after December 15, 2023. This accounting standard is effective in the first quarter of the Company's fiscal year ended September 30, 2025. The Company does not expect the adoption of this new guidance to have a material impact on the consolidated financial statements.

Depreciation expense totaled $3.3 million and $2.7 million during the fiscal years ended September 30, 2024 and 2023, respectively. During the fiscal years ended September 30, 2024 and 2023, the Company sold certain equipment and recognized a loss (gain) on sale of assets of $18.1 thousand and $(1.1) million.

During the fiscal year ended September 30, 2024, there was a long lived-asset impairment of leasehold improvements, net of $2.4 million attributable to the full shutdown of the remaining Alhambra Facility.

During the fiscal year ended September 30, 2023, for the reporting unit formerly known as Aerospace & Defense, an indication of goodwill impairment (after electing to quantitatively test goodwill) was a trigger to test long-lived assets. Recoverability of the long-lived assets was measured by comparing the carrying amount of the asset groups to the future net undiscounted cash flows expected to be generated by the asset groups. The comparison indicated that the assets were recoverable.

Long-lived assets consist of property, plant, and equipment. As of September 30, 2024 and 2023, approximately all of our long-lived assets were located in the United States.

NOTE 7. Intangible Assets and Goodwill

Intangible assets are amortized on a straight-line basis over the estimated useful life of: (a) 7.0 years for patents, (b) 8.0 years for customer relationships, and (c) 2.0-8.0 years for technology. A certain Company trademark is indefinite-lived.

concluded that the fair value exceeded the carrying value of such trademark of $0.9 million. Key assumptions utilized in the determination of fair value include expected future revenues and estimated royalty rates. While we believe the expectations and assumptions about the future are reasonable, they are inherently uncertain.

During the fiscal year ended September 30, 2023, the projects related to EMCORE Chicago's acquired IPR&D were completed and were classified as technology assets and assigned an eight-year useful life. With respect to a certain IPR&D project arising from the acquisition of S&N, it was determined during the fiscal year ended September 30, 2023, that the Company would abandon the project underlying the remaining IPR&D and the carrying value of $0.8 million was impaired.

During the fiscal year ended September 30, 2023, in accordance with ASC 350, the Company performed a quantitative (Step 1) analysis of goodwill utilizing a weighted income and market approach and concluded that the carrying value of the reporting unit that carried the goodwill (adjusted for trademark impairment) was greater than the fair value of equity of the reporting unit, and impairment expense of $19.0 million was recorded. As a result of this impairment charge, the goodwill balance was reduced to zero at September 30, 2023. Key assumptions utilized in the determination of fair value include forecasted financial performance of the Company. While we believe the expectations and assumptions about the future are reasonable, they are inherently uncertain.

NOTE 8. Benefit Plans

Table of Contents

We assumed a defined benefit pension plan (the “Pension Plan”) on April 29, 2022 as a result of the acquisition of S&N. The Pension Plan was frozen to new hires as of March 31, 2007 and employees hired on or after April 1, 2007 are not eligible to participate in the Pension Plan. On July 1, 2022, the Pension Plan was amended to freeze benefit plan accruals for participants. As a result of the freeze, a curtailment was triggered and a restatement of the benefit obligation and plan assets occurred, although no gain or loss resulted. The annual measurement date for the Pension Plan is September 30. Benefits are based on years of credited service at retirement. Annual contributions to the Pension Plan are not less than the minimum funding standards outlined in the Employee Retirement Income Security Act of 1974, as amended. We maintain the Pension Plan with the goal of ensuring that it is adequately funded to meet its future obligations. We did not make any contributions to the Pension Plan during the fiscal years ended September 30, 2024 and 2023.

Net pension asset is included as a component of other non-current assets on the consolidated balance sheets as of September 30, 2024 and 2023. As of September 30, 2024 and 2023, the Pension Plan assets consisted primarily of cash and cash equivalents. We manage a liability driven investment strategy intended to maintain fully-funded status.

401(k) Plan

We have a savings plan that qualifies as a deferred salary arrangement under Section 401(k) of the Internal Revenue Code. Under this savings plan, participating employees may defer a portion of their pretax earnings, up to the Internal Revenue Service annual contribution limit. Our matching contribution in cash for each of the fiscal years ended September 30, 2024 and 2023 was approximately $1.0 million and $1.3 million, respectively.

NOTE 10. Credit Agreement

Wingspire/Hale Credit Agreement

On August 9, 2022, EMCORE and S&N, our wholly-owned subsidiary, entered into that certain Credit Agreement with the lenders party thereto and Wingspire Capital LLC (“Wingspire”), as administrative agent for the lenders, as amended pursuant to that First Amendment to Credit Agreement dated as of October 25, 2022, among EMCORE and S&N, EMCORE Chicago, our wholly-owned subsidiary (together with the Company and S&N, the “Borrowers”), the lenders party thereto and Wingspire, to add EMCORE Chicago as a Borrower and include certain of its assets in the borrowing base (as amended, the “Credit

Table of Contents

Agreement”). The Credit Agreement provided for two credit facilities: (a) an asset-based revolving credit facility in an aggregate principal amount of up to $40.0 million, subject to a borrowing base consisting of eligible accounts receivable and eligible inventory (subject to certain reserves), and (b) a term loan facility in an aggregate principal amount of approximately $6.0 million.

On April 29, 2024, Wingspire, HCP-FVU, LLC, HCP Fund V-FVU, LLC and Bessel Holdings LLC (each an affiliate of Hale Capital Management, L.P. and collectively, “Hale” or “New Lenders”), and HCP-FVU, LLC, as administrative agent for New Lenders (in such capacity, the “Successor Agent”) entered into an Assignment Agreement (the “Assignment Agreement”) pursuant to which Hale acquired all of Wingspire’s interest in the credit facilities extended by Wingspire to the Company pursuant to the Credit Agreement and all of the Loan Documents (as defined in the Credit Agreement) and any other documents, instruments, certificates, financing statements and agreements relating to the Credit Agreement. In connection with the Assignment Agreement, the Company entered into a Forbearance Agreement and Second Amendment to Credit Agreement with S&N and EMCORE Chicago, Hale, and the Successor Agent dated April 29, 2024 (the “Forbearance Agreement”). Under the terms of the Forbearance Agreement, Hale agreed: (i) not to accelerate the obligations or exercise other default remedies under the Credit Agreement and related documents; (ii) not to enforce any of the provisions or terms of the Credit Agreement and the related collateral documents relating to the occurrence of one or more cash dominion trigger events; and (iii) to direct the Successor Agent not to accelerate the obligations, exercise default remedies or take any such enforcement action or enforcement of provisions under the Credit Agreement and related documents during the period (the “Forbearance Period”) beginning on April 29, 2024 through the earliest of: (i) May 31, 2024; (ii) the date that any breach or default occurs or is determined to have occurred under the Credit Agreement or any other related document, including the Forbearance Agreement; and (iii) the date that the Company initiates any judicial, administrative or arbitration proceeding against Hale or the Successor Agent. The Forbearance Agreement also amended the Credit Agreement, to, among other things, set a fixed interest rate of 12% per annum (with an additional 6% upon the occurrence and during the continuance of an event of default, which shall not apply during the Forbearance Period to any of the events of default as to which the forbearance applies) on each loan. The Forbearance Agreement reduced the aggregate principal amount that we could draw under the revolving credit facility from $40.0 million to $4.6 million, subject to a borrowing base consisting of eligible accounts receivable, eligible inventory and eligible equipment (subject to certain reserves). The Forbearance Agreement also provided that the Company could elect to pay all or a portion of the interest that would accrue under the Credit Agreement as payment-in-kind, which would allow the Company to increase the principal balance of the Loans due and payable upon maturity, rather than making interest payment in cash. In addition, the Forbearance Agreement provided for certain financial covenants, loosened the circumstances under which the Borrowers would have to comply with a fixed charge coverage ratio, and eliminated all restrictions relating to cash dominion.

On April 29, 2024 (the “Issuance Date”), in consideration of the Forbearance Agreement, the Company issued to the Successor Agent a warrant (the “Warrant”) to purchase an aggregate of 1,810,528 (post-reverse split) shares of the Company’s common stock at an exercise price of $2.73 per share. The Warrant is exercisable, at any time and from time to time, for 10 years following the Issuance Date. Under the terms of the Warrant, we have a right to force Successor Agent to exercise the Warrant under certain Forced Exercise Conditions (as defined in the Warrant) and issue a replacement warrant, and Successor Agent has a right to require us to purchase the unexercised portion of the Warrant under certain circumstances, including upon a Fundamental Transaction (as defined in the Warrant). If we are required to purchase the unexercised portion of the Warrant, we may elect to pay such repurchase price in the form of an unsecured promissory note. The Company accounted for the Warrant in accordance with ASC 815-40 Derivatives and Hedging - Contract in Entity's Own Equity and ASC 470-50 Debt - Modifications and Extinguishments. As there are provisions in the Warrant agreement that indicate that neither of the two criteria necessary for equity classification are met, the Company recorded the Warrant’s fair value using the Black-Scholes valuation method on date of issuance of approximately $5.1 million as a non-current liability in the consolidated balance sheet. As the Company was legally released as the primary obligor by Wingspire and there is no continuing debt to Wingspire, a corresponding value of $5.1 million was recorded as loss on extinguishment of debt in the consolidated statement of operations and comprehensive loss.

The Company has and will continue to subsequently remeasure the fair value of the Warrant each reporting period as long as the Warrant remains classified as a liability with changes in the fair value reported in loss on extinguishment of debt and change in fair value of warrant liability on the consolidated statements of operations and comprehensive loss. We believe that the assumptions used in the calculations of fair value of the warrant liability represent the best estimates of fair value.

As of September 30, 2024, using the Monte Carlo simulation valuation method, the fair value of the Warrant using Level 3 inputs was recorded as a $4.7 million non-current liability in the consolidated balance sheet and for the fiscal year ended September 30, 2024 the corresponding net expense of $2.6 million and $4.7 million is included in loss on extinguishment of debt and change in fair value of warrant liability in the consolidated statement of operations and comprehensive loss. See Note 13 - Equity for further discussion of the Warrant.

On August 5, 2024, we voluntarily prepaid approximately $9.4 million to repay in full all amounts outstanding and payable under the Credit Agreement, resulting in termination of the Credit Agreement. In connection with the termination of the Credit

Table of Contents

Agreement, the total amount repaid by the Company of approximately $9.4 million consisted of approximately $8.5 million of principal, approximately $0.8 million of accrued interest, including interest that would have accrued through the one-year anniversary of the Forbearance Agreement, approximately $0.1 million of prepayment premium and approximately $0.1 million of customary expenses of the Successor Agent and the Lenders.

For the fiscal years ended September 30, 2024 and 2023, the Company recorded income tax expense of approximately $29.0 thousand and $42.0 thousand, respectively. Income tax expense for the fiscal year ended September 30, 2024 is comprised primarily of state minimum tax expense. Income tax expense for the fiscal year ended September 30, 2023 is comprised primarily of a federal refund of AMT credit and state minimum tax expense.

For the fiscal years ended September 30, 2024 and 2023, the effective tax rate on operations was 0.1%. The Company uses some estimates to forecast permanent differences between book and tax accounting.

We have not provided for income taxes on non-U.S. subsidiaries’ undistributed earnings as of September 30, 2024 as we sold most of our foreign operations as of September 30, 2024.

All deferred tax assets have a full valuation allowance at September 30, 2024 and 2023. On a quarterly basis, the Company evaluates the positive and negative evidence to assess whether the more likely than not criteria has been satisfied in determining whether there will be further adjustments to the valuation allowance.

As of September 30, 2024, the Company had net operating loss carryforwards for U.S. federal income tax purposes of approximately $373.9 million which begin to expire in 2025. As of September 30, 2024, the Company had state net operating loss carryforwards of approximately $61.8 million which begin to expire in 2025. As of September 30, 2024, the Company also had tax credits (primarily foreign income and U.S. research and development tax credits) of approximately $0.1 million. The research credits begin to expire in 2025. Utilization of net operating loss and tax credit carryforwards are subject to a substantial annual limitation due to the ownership change limitations set forth in Section 382 (“Section 382”) of the Internal Revenue Code of 1986, as amended (the “Code”) and similar state provisions. The Company prepared an Internal Revenue Code 382 analysis to determine the annual limitations on the Company’s consolidated net operating loss carryforwards. As a result, of the $373.9 million of U.S. net operating loss carryforwards, approximately $278.6 million is subject to an annual limitation and $95.3 million of the net operating losses are not subject to an annual limitation. Of the $0.1 million tax credits, all of them are subject to annual limitation. Such annual limitations could result in the expiration of the net operating loss and tax credit carryforwards before utilization. As of September 30, 2024, the Company wrote-off $278.6 million of federal net operating losses and $0.1 million of tax credits, which are fully offset by a valuation allowance.

See Note 13 - Equity for information on the Company’s Tax Preservation Plan.

NOTE 12. Commitments and Contingencies

Leases

Table of Contents

We lease certain facilities and equipment under non-cancelable operating leases. Operating lease amounts exclude property taxes, insurance, and maintenance expenses on leased properties. As of September 30, 2024, our operating leases had remaining lease terms of approximately 1/2 year to 11 years, some of which included options to extend five additional years. During the fiscal years ended September 30, 2024 and 2023, the Company recorded $3.6 million and $3.7 million of operating lease expense, respectively. The Company’s finance leases and short-term leases are immaterial.

During the fiscal year ended September 30, 2023, there was a change in circumstances surrounding the use of our leased facilities and ROU assets due to the restructuring of our business and active pursuit of selling the discontinued operations and the indium phosphide wafer fabrication facility assets. Recoverability of the long-lived assets was measured by comparing the carrying amount of the asset groups to the future net undiscounted cash flows expected to be generated by the asset groups. The comparison indicated that certain of the asset groups was not recoverable, and an impairment of $1.4 million was recorded as this was the amount by which the carrying value of the asset group exceeded the related estimated fair value, which was based on discounted future operating cash flows.

We have entered into subleases with various third parties for portions of certain of our facilities. Aggregate sublease income pursuant to such subleases is expected to be approximately $0.6 million in the fiscal year ending September 30, 2025, approximately $1.0 million in the fiscal year ending September 30, 2026, and approximately $0.9 million in each of the fiscal years ending September 30, 2027 through September 30, 2031.

Maturities of operating lease liabilities as of September 30, 2024 were as follows:

Asset Retirement Obligations

ARO consists of legal requirements to decommission assets, restore the existing leased facilities to their original state, and perform certain environmental work due to the presence of a manufacturing fabrication operation. ARO includes assumptions related to renewal option periods for those facilities where we expect to extend lease terms. The Company recognizes its estimate of the fair value of its ARO in the period incurred in long-term liabilities and is also capitalized as property, plant and equipment. The fair value of ARO was estimated by discounting projected cash flows over the estimated life of the related assets using credit adjusted risk-free rates which ranged from 3.67% to 1.73%.

The following table summarizes ARO activity:

In the HieFo Sublease, Hiefo assumed certain end-of-lease remediation liabilities, including with respect to the portion of the Alhambra Facility related to indium phosphide wafer fabrication, where a substantial amount of remediation is expected to be required. As such, the Company performed a reassessment of its ARO by engaging an independent third-party. This resulted in a reduction to the ARO liability of approximately $2.1 million, which was recorded to other income in the consolidated statement of operations and comprehensive loss.

Indemnifications

We have agreed to indemnify certain customers against claims of infringement of intellectual property rights of others in our sales contracts with these customers. Historically, we have not paid any claims under these customer indemnification obligations. We enter into indemnification agreements with each of our directors and executive officers pursuant to which we agree to indemnify them for certain potential expenses and liabilities arising from their status as a director or executive officer of the Company. We maintain director and officer insurance, which covers certain liabilities relating to our obligation to indemnify our directors and executive officers in certain circumstances. It is not possible to determine the aggregate maximum potential loss under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular claim.

Legal Proceedings

We are subject to various legal proceedings, claims, and litigation, either asserted or unasserted, that arise in the ordinary course of business. The outcome of these matters is currently not determinable and we are unable to estimate a range of loss, should a loss occur, from these proceedings. The ultimate outcome of legal proceedings involves judgments, estimates, and inherent uncertainties and the results of these matters cannot be predicted with certainty. Professional legal fees are expensed when incurred. We accrue for contingent losses when such losses are probable and reasonably estimable. In the event that estimates or assumptions prove to differ from actual results, adjustments are made in subsequent periods to reflect more current information. Should we fail to prevail in any legal matter, or should several legal matters be resolved against the Company in the same reporting period, then the financial results of that particular reporting period could be materially affected.

Intellectual Property Lawsuits

We protect our proprietary technology by applying for patents where appropriate and, in other cases, by preserving the technology, related know-how, and information as trade secrets. The success and competitive position of our product lines are impacted by the ability to obtain intellectual property protection for research and development efforts. We have, from time to time, exchanged correspondence with third parties regarding the assertion of patent or other intellectual property rights in connection with certain of our products and processes.

Resilience Litigation

In February 2021, Resilience Capital (“Resilience”) filed a complaint against us with the Delaware Chancery Court containing claims arising from the February 2020 sale of SDI’s real property (the “Concord Property Sale”) located in Concord, California (the “Concord Real Property”) to Eagle Rock Holdings, LP (“Eagle Rock Holdings”) and that certain Single-Tenant Triple Net Lease, dated as of February 10, 2020, entered into by and between SDI and Eagle Rock Holdings, pursuant to which SDI leased from Eagle Rock Holdings the Concord Real Property for a 15-year term. The Resilience complaint sought, among other items, (a) a declaration that the Concord Property Sale included a non-cash component, (b) a decree requiring us and Resilience to follow the appraisal requirements set forth in that certain Purchase and Sale Agreement (the “SDI Purchase Agreement”), dated as of June 7, 2019, by and among the Company, The Resilience Fund IV, L.P., The Resilience Fund IV-A, L.P., Aerospace Newco Holdings, Inc. and Ember Acquisition Sub, Inc., (c) recovery of Resilience’s costs and expenses, and (d) pre- and post-judgment interest.

Table of Contents

In April 2021, we filed with the Delaware Chancery Court our answer to the Resilience complaint and counterclaims against Resilience, in which we are seeking, among other items, (a) dismissal of the Resilience complaint and/or granting of judgment in favor of EMCORE with respect to the Resilience complaint, (b) entering final judgment against Resilience awarding damages to us for Resilience’s fraud and breaches of the SDI Purchase Agreement in an amount to be proven at trial and not less than $1.6 million, (c) a judicial determination of the respective rights and duties of us and Resilience under the SDI Purchase Agreement, (d) an award to us of costs and expenses, and (e) pre- and post-judgment interest.

In April 2023, we and Resilience entered into a Settlement and Release Agreement (the “Resilience Settlement Agreement”). The material financial terms of the Resilience Settlement Agreement required (i) a payment of $0.5 million by us to Resilience, which payment was made by us during the three months ended June 30, 2023, (ii) appraisals of the Concord Real Property, conducted in 2023 with a date of value as of January 2, 2020, which resulted in a further payment obligation by us in an amount equal to approximately $1.3 million, which payment was made by us in October 2023, and (iii) a mutual release of all claims, including claims arising under the SDI Purchase Agreement, and a dismissal of the litigation by all parties. On October 10, 2023, the Delaware Chancery Court granted the parties' stipulation of dismissal with prejudice to the Delaware Chancery Court of all claims made by each party.

In April 2023, the underwriters of the representation and warranty insurance policies the Company acquired in connection with the SDI Purchase Agreement agreed to pay the Company $1.2 million within 15 business days in exchange for a release of any and all claims under the policies. We received payment during the three months ended June 30, 2023.

NOTE 13. Equity

Tax Preservation Plan

On September 28, 2023, our Board of Directors approved and adopted a Section 382 Tax Benefits Preservation Plan, dated as of September 28, 2023, by and between the Company and Equiniti Trust Company, LLC, as rights agent (the “Rights Agent”) (the “Section 382 Tax Benefits Preservation Plan”). Pursuant to the Section 382 Tax Benefits Preservation Plan, the Board of Directors declared a dividend of one preferred share purchase right (each, a “Right”) for each outstanding share of common stock. The dividend is distributable to shareholders of record as of the close of business on October 12, 2023.

The Board of Directors adopted the Section 382 Tax Benefits Preservation Plan to diminish the risk that the Company could experience an “ownership change” as defined in Section 382 of the Code, which could substantially limit or permanently eliminate the Company’s ability to utilize its net operating loss carryovers (collectively, the “NOLs”) to reduce potential future income tax obligations. Under the Code and the regulations promulgated thereunder by the U.S. Treasury Department, these NOLs may be “carried forward” in certain circumstances to offset any current and future taxable income and thus reduce federal income tax liability, subject to certain requirements and restrictions. While the amount and timing of the Company’s future taxable income cannot be predicted with any certainty and, accordingly, the Company cannot predict the amount of these NOLs that will ultimately be used to reduce its income tax liability, to the extent that the NOLs do not otherwise become limited, these NOLs could be a potentially valuable asset to the Company. As of September 30, 2024 and 2023, the Company had federal net operating loss carryforwards of approximately $373.9 million and $391.5 million, respectively.

In general, under Section 382, an “ownership change” occurs if a shareholder or a group of shareholders who are deemed to own at least 5% of the common stock individually or collectively increase their ownership by more than 50 percentage points over their lowest ownership percentage within a rolling three-year period. If an ownership change occurs, Section 382 imposes an annual limit on the amount of the Company’s NOLs that can be used to offset the Company’s federal taxable income equal to the product of the total value of the Company’s outstanding equity immediately prior to the ownership change (reduced by certain items specified in Section 382) and the federal long-term tax-exempt interest rate in effect for the month of the ownership change. A number of complex rules apply to calculating this annual limit and there are several special rules that, depending on the rule involved, may apply to reduce or increase such limit. The Company believes that on February 14, 2024, an “ownership change” occurred under Section 382, resulting in a decrease of total remaining federal NOLs to approximately $50.0 million and imposing an annual limit on the amount of the Company’s NOLs that can be used to offset the Company’s federal taxable income equal to $0.8 million for the subsequent 14 year period. If an additional ownership change were to occur, the limitations imposed by Section 382 could result in a substantial delay in the timing of the usage of the remaining NOLs or in a material amount or all of the remaining NOLs expiring unused and, therefore, significantly impair or eliminate the value of such NOLs. While the Company periodically monitors its NOLs, the complexity of Section 382’s provisions and the limited knowledge any public company has about the ownership of its publicly traded stock make it difficult to determine whether an ownership change has in fact occurred.

The Section 382 Tax Benefits Preservation Plan is intended to act as a deterrent to any person or group acquiring beneficial ownership of 4.99% or more of the outstanding common stock without the approval of the Board of Directors. A person who

Table of Contents

acquires, without the approval of the Board of Directors, beneficial ownership (other than as a result of repurchases of stock by the Company, dividends or distributions by the Company or certain inadvertent actions by shareholders) of 4.99% or more of the outstanding common stock (including any ownership interest held by that person’s Affiliates and Associates as defined under the Section 382 Tax Benefits Preservation Plan) could be subject to significant dilution. Shareholders who beneficially own 4.99% or more of the outstanding common stock prior to the first public announcement by the Company of the Board of Directors’ adoption of the Section 382 Tax Benefits Preservation Plan will not trigger the Section 382 Tax Benefits Preservation Plan so long as they do not acquire beneficial ownership of additional shares of the common stock (other than pursuant to a dividend or distribution paid or made by the Company on the outstanding shares of common stock or pursuant to a split or subdivision of the outstanding shares of common stock) at a time when they still beneficially own 4.99% or more of such stock. In addition, the Board of Directors retains the sole discretion to exempt any person or group from the penalties imposed by the Section 382 Tax Benefits Preservation Plan.

Reverse Stock Split

On March 15, 2024, the Company’s shareholders approved an amendment to the Company’s certificate of incorporation to effect a reverse split of the Company’s outstanding stock at a ratio ranging from 5:1 to 12:1 at the sole discretion of the Board of Directors of the Company. On March 15, 2024, the Board of Directors approved a reverse split and set a reverse stock split ratio of 10:1 for the Company's outstanding share of the Company's common stock. The reverse stock split was effective on April 1, 2024. As of the effective time of the reverse split, every 10 issued and outstanding shares of the Company’s common stock was automatically reclassified into one issued and outstanding share of the Company’s common stock, with any fractional shares being rounded up to the next whole share. Proportionate adjustments were made to the number of shares of common stock underlying the Company’s outstanding equity awards, warrants, the number of shares issuable under its equity incentive plans and other existing agreements, as well as the exercise or conversion price, as applicable. All previously reported equity and loss per share information amounts have been adjusted for the reverse stock split in the consolidated financial statements for 2023.

Hale Warrant

On April 29, 2024 (the “Issuance Date”), in consideration of the Forbearance Agreement, the Company issued to Successor Agent the Warrant to purchase an aggregate of 1,810,528 (post-reverse split) shares of the Company’s common stock at an exercise price of $2.73 per share. The Warrant is exercisable, at any time and from time to time, for 10 years following the Issuance Date. Under the terms of the Warrant, the Company has a right to force the Successor Agent to exercise the Warrant under certain Forced Exercise Conditions (as defined in the Warrant) and issue a replacement warrant, and the Successor Agent has a right to require the Company to purchase the unexercised portion of the Warrant under certain circumstances, including upon a Fundamental Transaction (as defined in the Warrant). If the Company is required to purchase the unexercised portion of the Warrant, the Company may elect to pay such repurchase price in the form of an unsecured promissory note.

The Warrant provides for certain adjustments to the exercise price and the number of shares issuable upon exercise of the Warrant in certain circumstances, including a full-ratchet anti-dilution adjustment in connection with certain issuances of common stock and convertible securities by the Company below the then current exercise price of the Warrant. The Company also agreed to register for resale with the SEC the shares issuable upon exercise of the Warrant. The Warrant contains restrictions on the Successor Agent’s ability to exercise the Warrant, such that the Successor Agent shall not be entitled to exercise the Warrant if the total number of shares of common stock then beneficially owned by the Successor Agent, and its affiliates and any other persons whose beneficial ownership of common stock would be aggregated with the Successor Agent’s other ownership of the Company’s common stock, exceeds 4.999% of the total number of issued and outstanding shares of common stock of the Company (the “Threshold Percentage”). However, the Successor Agent has the right at any time and from time to time, to increase the Threshold Percentage to 9.999%. Additionally, the Successor Agent shall not have the right to exercise the Warrant if the total number of shares of common stock then beneficially owned by the Successor Agent , and its affiliates and any other persons whose beneficial ownership of common stock would be aggregated with the Successor Agent’s other ownership of the Company’s common stock, exceeds 19.99%, unless shareholder approval is obtained by the Company, as may be required by the applicable rules and regulations of the Nasdaq Stock Market LLC (“Nasdaq”) or any such other exchange on which the Company’s shares are then listed, or unless such shareholder approval requirement has been waived by Nasdaq. Notwithstanding anything to the contrary in the Warrant, the sum of the number of shares of common stock that may be issued under the Warrant is limited to 19.99% of the Company’s outstanding shares of common stock as of the issuance date of the Warrant (the “Exchange Cap”), unless shareholder approval is obtained by the Company to issue more than the Exchange Cap, as may be required by the applicable rules and regulations of Nasdaq or any such other exchange on which the Company’s shares are then listed, or unless such shareholder approval requirement has been waived by Nasdaq. The initial fair value of the warrant of $5.1 million was estimated using the Black-Scholes valuation method and was recorded as a long-term liability on the consolidated balance sheet. The change in fair value of the warrant liability using the Monte Carlo simulation valuation method for the fiscal year ended September 30, 2024 was $4.7 million and is included in the consolidated statements of

operations and comprehensive loss on the line item captioned “Loss on extinguishment of debt and change in fair value of warrant liability.” See Note 10 - Credit Agreement for further information.

Equity Plans

We provide long-term incentives to eligible officers, directors, and employees in the form of equity-based awards. We maintain three equity incentive compensation plans, collectively described as our “Equity Plans”: (a) the 2010 Equity Incentive Plan (the “2010 Plan”), (b) the Amended and Restated 2019 Equity Incentive Plan (the “2019 Plan”), and (c) the 2022 New Employee Inducement Plan.

We issue new shares of common stock to satisfy awards granted under our Equity Plans. In December 2023, our Board of Directors approved an amendment to the 2019 Plan, which, following shareholder approval at our 2024 annual meeting of shareholders in March 2024, increased the maximum number of shares of the Company’s common stock that may be issued or transferred pursuant to awards under the 2019 Plan by an additional 0.8 million shares.

Stock Options

Most stock options vest and become exercisable over four years to five years and have a contractual life of ten years. Certain stock options awarded are intended to qualify as incentive stock options pursuant to Section 422A of the Code.

The Company has estimated the fair value of each option grant on the date of grant using the Black-Scholes option-pricing model. The expected volatility assumption is based on the historical daily price data of the Company’s common stock over a period equivalent to the weighted average expected life of the Company’s options. The expected term of options granted is derived using assumed exercise rates based on historical exercise patterns and represents the period of time the options granted are expected to be outstanding. The risk-free interest rate is based on the actual U.S. Treasury zero-coupon rates for bonds matching the expected term of the option as of the option grant date. The dividend yield of zero is based upon the fact that the Company has not historically declared or paid cash dividends, and does not expect to declare or pay dividends in the foreseeable future.

The following table summarizes stock option activity under the Equity Plans for the fiscal year ended September 30, 2024:


	Number of Shares	Weighted Average Exercise Price		Weighted Average Remaining Contractual Life (in years)	Aggregate Intrinsic Value (*) (in thousands)
Outstanding as of September 30, 2023	900	$	45.95

Vested and expected to vest as of September 30, 2024	541	$	49.73	0.1	$	—

___________________________________________

(*) Intrinsic value for stock options represents the “in-the-money” portion or the positive variance between a stock option’s exercise price and the underlying stock price.

As of September 30, 2024, there was no unrecognized stock-based compensation expense related to non-vested stock options granted under the Equity Plans.

Valuation Assumptions

There were no stock option grants for the fiscal years ended September 30, 2024 and 2023.

Time-Based Restricted Stock

Time-based restricted stock units (“RSUs”) granted to employees under the 2010 Plan, the 2019 Plan, or the 2022 New Employee Inducement Plan typically vest over three to four years and are subject to forfeiture if employment terminates prior to the vesting or lapse of the restrictions, as applicable. RSUs are not considered issued or outstanding common stock until they vest. The value of RSUs is determined by the stock price on the grant date.

Table of Contents

The following table summarizes the activity related to RSUs subject to time-based vesting requirements for the fiscal year ended September 30, 2024:


	RSUs
	Number of Shares	Weighted Average Grant Date Fair Value
Non-vested as of September 30, 2023	402,463	$	20.40
Granted	980,611	1.40
Vested	(110,952)	24.89
Forfeited	(271,629)	14.57
Non-vested as of September 30, 2024	1,000,493	$	2.87

As of September 30, 2024, there was approximately $2.2 million of remaining unamortized stock-based compensation expense associated with RSUs, which will be expensed over a weighted average remaining service period of approximately 2.0 years. The 1.0 million outstanding non-vested and expected to vest RSUs have an aggregate intrinsic value of $2.2 million and a weighted average remaining contractual term of 1.3 years. For the fiscal years ended September 30, 2024 and 2023, the intrinsic value of RSUs vested was approximately $0.4 million and $1.3 million, respectively. The weighted average grant date fair value of RSUs granted during the fiscal years ended September 30, 2024 and 2023 was $1.40 and $10.00 per share, respectively.

Performance-Based Restricted Stock

Performance-based restricted stock units (“PSUs”) granted to employees under the 2019 Plan typically vest over three years and are subject to forfeiture in whole, if employment terminates, or in whole or in part, if specified vesting conditions are not satisfied in each case prior to vesting. PSUs are not considered issued or outstanding common stock until they vest. PSUs that are granted to executive officers and key employees are provided as long-term incentive compensation that is based on relative total shareholder return, which measures performance against the Russell Microcap Index.

PSUs are valued based on a Monte Carlo simulation model to reflect the impact of the PSUs' market condition. The probability of satisfying a market condition is considered in the estimation of the grant-date fair value for PSUs and the compensation cost is not reversed if the market condition is not achieved, provided the requisite service has been provided.

The following table summarizes the activity related to PSUs for the fiscal year ended September 30, 2024:


	PSUs
	Number of Shares (at target)	Weighted Average Grant Date Fair Value
Non-vested as of September 30, 2023	170,442	$	34.58
Vested	(5,590)	2.95
Forfeited	(115,886)	38.85
Non-vested as of September 30, 2024	48,966	$	28.40

As of September 30, 2024, there was approximately $0.3 million of remaining unamortized stock-based compensation expense associated with PSUs, which will be expensed over a weighted average remaining service period of approximately 0.5 years. The 49.0 thousand outstanding non-vested and expected to vest PSUs have an aggregate intrinsic value of approximately $0.1 million and a weighted average remaining contractual term of 0.5 years. For each of the fiscal years ended September 30, 2024 and 2023, the intrinsic value of PSUs vested was $20.0 thousand and $312.0 thousand. There were no PSUs granted during the fiscal year ended September 30, 2024. The weighted average grant date fair value of PSUs granted during the fiscal year ended September 30, 2023 was $9.70 per share.

Capital Stock

Authorized capital stock consists of 100 million shares of common stock, no par value, and 5,882,352 shares of preferred stock, $0.0001 par value. No shares of preferred stock were outstanding as of September 30, 2024.

On August 23, 2023, we closed our offering of 22,600,000 shares of our common stock at a price of $0.50 per share, and, to certain investors, pre-funded warrants (each, a “Pre-Funded Warrant”) to purchase 11,900,000 shares of our common stock at a price of $0.49999999 for each pre-funded warrant (which represents the per share public offering price for our common stock in such offering less the $0.00000001 per share exercise price for each such Pre-Funded Warrant), resulting in net proceeds to us from the offering, after deducting the placement agent commissions and other offering expenses, of approximately $15.6 million. The shares were sold by us pursuant to an Underwriting Agreement, dated as of August 17, 2023, between us and the Craig-Hallum Capital Group LLC as the sole managing underwriter.

On February 17, 2023, we closed our offering of 15,454,546 shares of our common stock at a price of $1.10 per share, resulting in net proceeds to us from the offering, after deducting the placement agent commissions and other offering expenses, of $15.4 million. The shares were sold by us pursuant to a Securities Purchase Agreement, dated as of February 17, 2023, between the Company and each purchaser named in the signature pages thereto and a Placement Agency Agreement, dated as of February 15, 2023, by and between the Company and A.G.P./Alliance Global Partners.

As of September 30, 2024 and 2023, we had 9.8 million and 8.4 million shares of common stock issued and outstanding, respectively. There were no shares of preferred stock issued and outstanding as of September 30, 2024 and 2023.

Weighted average antidilutive options, unvested RSUs, unvested PSUs and common shares underlying warrants excluded from the computation reflective of reverse stock split effective April 1, 2024	465		331

Basic earnings per share (“EPS”) is computed by dividing net loss for the period by the weighted-average number of common stock and pre-funded warrants outstanding during the period. Diluted EPS is computed by dividing net loss for the period by the weighted average number of common stock and pre-funded warrants outstanding during the period, plus the dilutive effect of outstanding RSUs, PSUs, and stock options, as applicable pursuant to the treasury stock method. Basic and diluted shares outstanding includes the weighted average of the effect of the Company's outstanding pre-funded warrants as the exercise price of such pre-funded warrants requires nominal consideration to be given for the delivery of the corresponding shares of common stock. Certain of the Company's outstanding share-based awards, noted in the table above, were excluded because they were anti-dilutive, but they could become dilutive in the future. The anti-dilutive stock options and shares of outstanding and unvested restricted stock were excluded from the computation of earnings per share for the fiscal years ended September 30, 2024 and 2023 due to the Company incurring a net loss for such periods.

Future Issuances

Common stock reserved for future issuances as of September 30, 2024 was as follows:


			Amount
Exercise of outstanding stock options			541
Unvested RSUs			1,000,493
Unvested PSUs (at 100% maximum payout)			48,966
Issuance of stock-based awards under the Equity Plans			274,967

NOTE 17. Discontinued Operations

In April 2023, we initiated a restructuring program that includes the strategic shutdown of our Broadband business segment (including our cable TV, wireless, sensing and chips product lines) and the discontinuance of our defense optoelectronics product line. During the quarter ended September 30, 2023, the Broadband business segment and defense optoelectronics product line were considered as held for sale based upon (i) the existence of an executed non-binding letter of intent entered into between us and PF to sell our Broadband business segment (other than our chips business line) and our defense optoelectronics product line and (ii) in consideration of ongoing negotiations for the sale of the chips business line.

In October 2023, the Company entered into an Asset Purchase Agreement, by and among the Company, PF, and Ortel, pursuant to which the Company consummated the PF Transaction. The PF Transaction excluded the Company’s chip business, indium phosphide wafer fabrication facilities and all assets not primarily related to the Businesses.

The signing and closing of the PF Transaction occurred simultaneously, except with respect to the assets of the Company located in China. In November 2023, the Company transferred to the Buyer, and the Buyer assumed, substantially all of the assets and liabilities of each of the Company’s subsidiaries in China.

In connection with the PF Transaction, the parties entered a transition services agreement pursuant to which the Company is providing certain migration and transition services to facilitate an orderly transition of the operation of the Businesses to the Buyer in the 12-month period following consummation of the PF Transaction, and the Company and the Buyer entered into a sublease pursuant to which the Company is subleasing to the Buyer one of the Company’s buildings (occupying approximately 12,500 square feet) at its Alhambra, California facility: initially, for the 12-month period immediately following the closing of the PF Transaction without payment of rent and, for the period beginning October 12, 2024 and ending March 31, 2025, for rent in an amount approximately equal to the pro rata portion of the rent payable for such portion of the facility by the Company under the Company’s master lease. With respect to the Buyer’s assumption of our manufacturing agreement with our electronics manufacturing services (“EMS”) provider for our cable TV products, the Company (i) made a payment to the EMS provider in the amount of approximately $0.4 million immediately prior to the closing of the transaction and (ii) provided a guaranty of PF’s and the Buyer’s obligations with respect to payment of certain long-term liabilities that were originally agreed to and set forth in the manufacturing agreement and assigned to PF and the Buyer in the PF Transaction, in an aggregate amount expected to equal up to approximately $5.5 million, approximately $4.3 million of which will not become payable, if at all, until January 2026, provided that if such guaranty is exercised by the EMS provider, the Company will have the right to require the Buyer to reassign to the Company all intellectual property assigned to the Buyer in the PF Transaction and the Company will have the right to recover damages from PF and the Buyer.

On April 30, 2024, the Company entered into the HieFo Purchase Agreement with HieFo and consummated the Chips Transaction. With respect to the $2.9 million purchase price, $1.0 million of was received by the Company in the quarter ended December 31, 2023 in connection with the execution of a non-binding letter of intent related to the Chips Transaction and $1.9 million of which was received by the Company upon closing of the Chips Transaction.

In connection with the Chips Transaction, the parties entered a transition services agreement pursuant to which the Company is providing certain migration and transition services to facilitate an orderly transition of the operation of the chips business line to HieFo in consideration for fees payable to the Company for such services as agreed between the Company and HieFo for a period of up to 12 months following consummation of the Chips Transaction, and the Company and HieFo entered into a sublease pursuant to which the Company is subleasing to HieFo (i) initially, all of one building and a portion of a second building (collectively occupying approximately 21,750 square feet) and (ii) beginning January 1, 2026, all of such two buildings (collectively occupying approximately 25,000 square feet) at the Company’s Alhambra, California facility through the remaining term of the Company’s lease of such facility ending September 30, 2031, with a pro rata portion of the rent for such facility being payable to the Company beginning on July 1, 2024 (the “HieFo Sublease”).

As of September 30, 2023, the Broadband business segment and defense optoelectronics business line were disclosed as held for sale in the consolidated balance sheet. As of September 30, 2024, there were no assets or liabilities that were classified as held for sale on the consolidated balance sheet.

The following table presents key components of assets and liabilities that were classified as held for sale on the consolidated balance sheet as of September 30, 2023:

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheet of EMCORE Corporation (the “Company”) as of September 30, 2024, and the related consolidated statements of operations and comprehensive loss, shareholders’ equity and cash flows for the year then ended, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of September 30, 2024, and the results of its operations and its cash flows for the year then ended, in conformity with accounting principles generally accepted in the United States of America.

Going Concern

The accompanying consolidated financial statements have been prepared assuming that the entity will continue as a going concern. As discussed in Note 2 to the consolidated financial statements, the entity has suffered recurring losses from operations that raise substantial doubt about its ability to continue as a going concern. Management's plans in regard to these matters are also described in Note 2. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the entity's internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audit provides a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Evaluation of the Going Concern Assessment

Critical Audit Matter Description

As described in Note 2 to the consolidated financial statements, significant judgment is exercised by the Company in determining whether there is substantial doubt that the Company will continue as a going concern. Specifically, the Company’s forecasted cash flows are sensitive to significant assumptions such as projected revenue and projected operating results, all of which are affected by the expected future market or economic conditions.

Table of Contents

Given these factors, the related audit effort in evaluating management’s judgments in forecasting operating results which factor into the Company’s going concern assessment was challenging, subjective, and complex and required a high degree of auditor judgment.

How our Audit Addressed the Critical Audit Matter

Our principal audit procedures related to the evaluation of the going concern assessment included the following:

•We gained an understanding of and evaluated the design and implementation of the Company’s controls to that address the risk of material misstatement related to going concern.

•We evaluated management’s significant accounting policies related to going concern for reasonableness.

•We evaluated the reasonableness of the Company’s forecasted revenue, operating results, and cash flows by comparing those forecasts to underlying business strategies, including customer relationships and the Company’s ability to obtain new orders, and to historical results. In addition, we performed sensitivity analyses related to the key inputs used in the Company’s forecasted cash flows, including evaluating whether the changes in the assumptions would result in a material change in forecasted cash flows.

•We evaluated management’s ability to accurately forecast future cash flows by comparing the Company’s historical forecasted sales, operating results and cash flow forecasts to actual results.

Valuation of Warrant

Critical Audit Matter Description

As described in Note 10 to the consolidated financial statements, the Company issued a warrant that is classified as a liability and is required to be fair valued at each reporting period. The valuation of this warrant involves significant judgment and estimation, particularly in determining the appropriate valuation model and the inputs used in the model, such as volatility, risk-free interest rate, dividend yield and expected term.

Given these factors, the related audit effort in evaluating management’s judgments in determining the valuation of the warrant was challenging, subjective, and complex and required a high degree of auditor judgment.

How our Audit Addressed the Critical Audit Matter

Our principal audit procedures related to the valuation of the warrant at September 30, 2024, included the following:

•We gained an understanding of and evaluated the design and implementation of the Company’s controls that address the risk of material misstatement related to the valuation of the warrant.

•We evaluated management’s significant accounting policies related to the valuation of the warrant for reasonableness.

•We assessed the appropriateness of the valuation model used by the Company and tested the mathematical accuracy of the model.

•We evaluated the reasonableness of the significant assumptions used in the valuation model, including volatility, risk-free interest rate, dividend yield and expected term, by comparing them to available market data and historical data.

•We involved our valuation specialists to assist in evaluating the appropriateness of the valuation model and the reasonableness of the significant assumptions.

•We tested the appropriateness of the underlying data used in the valuation model.

ITEM 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure.

None.

ITEM 9A. Controls and Procedures.

Disclosure Controls and Procedure

Management, with the participation of the Company’s Interim Chief Executive Officer (Principal Executive Officer) and Chief Financial Officer (Principal Financial Officer), evaluated the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the

Table of Contents

“Exchange Act”)), as of the end of the period covered by this Annual Report on Form 10-K. Based upon this evaluation, the Interim Chief Executive Officer and Chief Financial Officer concluded that as a result of the material weaknesses in internal control over financial reporting as described below, our disclosure controls and procedures were not effective as of the end of the period covered by this report.

Management’s Annual Report on Internal Control Over Financial Reporting

Our disclosure controls and procedures, (as defined in Rules 13a-15(e) and 15d-15(e) promulgated under the Exchange Act), are designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. We designed our disclosure controls and procedures to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal executive and principal financial officer, to allow timely decisions regarding required disclosure. Our Interim Chief Executive Officer and Chief Financial Officer, with assistance from other members of our management, have reviewed the effectiveness of our disclosure controls and procedures as of September 30, 2024 and, based upon this evaluation, have concluded that our disclosure controls and procedures contained material weaknesses in internal control over financial reporting which were identified by the Company. A material weakness is a deficiency or combination of deficiencies in internal controls over financial reporting, such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis.

As of September 30, 2023, the Company determined that communications with regard to internal control objectives were not effective to require employees to report the existence of new or novel arrangements for technical accounting review, which resulted in the Company’s failure to design and implement effective controls over such transactions. As of September 30, 2023, the control deficiency resulted in a material error associated with identification of the existence of certain insurance premium and supplier financing agreements, whereby (i) certain items on the Company’s consolidated balance sheet were underreported in “Other current assets” with a consistent dollar amount underreported for “Financing payable” within the Company’s consolidated balance sheet and (ii) certain items on the Company’s consolidated statements of cash flows were underreported in Payments to financing payables within “Cash flows from financing activities” and similar such underreporting of such items in other assets in “Cash flows from operating activities”. This error was corrected in the consolidated financial statements as of and for the fiscal year ended September 30, 2023, and as a result, this material weakness did not result in a material misstatement to the annual or interim consolidated financial statements previously filed and/or included in this Annual Report on Form 10-K. This material weakness has not been remediated as of September 30, 2024.

As of September 30, 2024, we identified a separate material weakness in internal control related to insufficient accounting and finance resources, particularly a lack of qualified project accounting and cost accounting personnel. This led to untimely preparation and review of account reconciliations by staff untrained in certain processes resulting in multiple errors. Our review of certain asset and liability accounts within the Company's consolidated balance sheet was not sufficient to ensure that these accounts, along with revenue and cost of revenues within the Company's statement of operations and comprehensive loss, reflected accurate amounts based on reconciliations and supporting documentation. These errors were corrected in the consolidated financial statements as of and for the fiscal year ended September 30, 2024, and as a result, this material weakness did not result in a material misstatement to the consolidated financial statements included in this Annual Report on Form 10-K. This material weakness has not been remediated as of September 30, 2024

Management’s Remediation Plan

We have identified and are implementing actions intended to improve the effectiveness of our internal control over financial reporting and disclosure controls and procedures and will continue to do so until such remediation is complete. Management intends to remediate the first material weakness described above primarily through a combination of (i) revisiting and clarifying, as needed, Company policies with respect to required communications when entering binding arrangements, (ii) communicating to employees the importance of elevating new and/or novel arrangements for technical accounting oversight in their respective internal control areas. Such communication, including compliance with existing or revised policy, is expected to be delivered through employee training. Management also intends to remediate the second material weakness described above, by increasing the number of accounting staff personnel, particularly project accounting and cost accounting, to levels sufficient enough to enable timely completion and review of account reconciliations. Management may reassess and modify such remediation plan to the extent the Proposed Transaction is consummated during fiscal 2025.

Changes in Internal Control Over Financial Reporting

During the quarter ended June 30, 2024, our accounting analysis of the Warrant issued to Hale on April 29, 2024 was not sufficiently robust to result in appropriate classification of the instrument as a liability with change in its fair value remeasured at the end of every quarterly reporting period and recorded in the consolidated statement of operations and thus we concluded

Table of Contents

that the control failure was a material weakness. During the fourth quarter of fiscal 2024, we implemented and executed new disclosure controls over our accounting analysis of the Warrant. In addition, we enhanced our controls via consultations with external specialists and reviews of the work performed by the external specialist to ensure appropriate classification of the instrument as a liability with change in its fair value remeasured at the end of every quarterly reporting period and recorded in the consolidated statement of operations and comprehensive loss. Management has concluded that this material weakness was remediated as of September 30, 2024, as a result of the changes in internal control over financial reporting described above.

There were no changes in the Company’s internal control over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) promulgated under the Exchange Act) during the quarter ended September 30, 2024 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting other than as related to the identification of and the remediation of the material weakness described above. The design of processes, systems, and controls allows for remote execution with accessibility to secure data.

Limitations on Effectiveness of Controls and Procedures

Management, including the Company’s Interim Chief Executive Officer and Chief Financial Officer, does not expect that disclosure controls or internal controls over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Further, the design of a control system must reflect the fact that there are resource constraints and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by individual acts, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based, in part, upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with associated policies or procedures. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

ITEM 11. Executive Compensation.

COMPENSATION DISCUSSION AND ANALYSIS

This Compensation Discussion and Analysis describes the material elements of the Company’s executive compensation program and analyzes the compensation decisions made for the executive officers included in the Summary Compensation Table (the “Named Executive Officers”) for the fiscal year ended September 30, 2024 (“fiscal 2024”).

2024 Named Executive Officers

Our Named Executive Officers for fiscal 2024 were:

Matthew Vargas – VP, Sales and Interim Chief Executive Officer (our “interim CEO”)

Tom Minichiello – Chief Financial Officer (our “CFO”)

Iain Black – former SVP, Operations

Jeffrey Rittichier – former Chief Executive Officer (our “former CEO”)

Because we qualify as a “smaller reporting company”, we have only four Named Executive Officers for fiscal 2024.

Table of Contents

Executive Compensation Program Highlights

Highlights of our executive compensation program include:

•During fiscal 2024, we continued our performance-based annual short-term incentive program. With respect to our interim CEO, 100% of the target bonus opportunity during fiscal 2024 was tied to the Company’s achievement of adjusted cash flow breakeven (excluding restructuring costs) by the end of the quarter ending September 30, 2024 (which the Compensation Committee determined in December 2024 had been achieved and that therefore a short-term incentive bonus of $187,500 for fiscal 2024 was payable to our interim CEO). With respect to each of our CFO and former CEO, 100% of the target bonus opportunity during fiscal 2024 was tied to the Company’s achievement of both a fiscal 2024 free cash flow target and a minimum cash balance as of September 30, 2024 (which the Compensation Committee determined in December 2024 had not been achieved and that therefore no short-term incentive bonus was payable for fiscal 2024 to our CFO).

•We do not have any agreements with our Named Executive Officers that provide for “single trigger” change in control cash payments. Our change in control severance agreement with our interim CEO limits cash severance benefits for a qualifying termination of employment to a “0.5x” multiple, whether or not the qualifying termination of employment is in connection with a change in control, and our employment agreement with our CFO limits cash severance benefits for a qualifying termination of employment to a “1x” multiple, whether or not the qualifying termination of employment is in connection with a change in control. While the employment agreement with our former CEO that was entered into in December 2014 provided for “single trigger” acceleration and immediate vesting of 50% of his outstanding equity awards in the event of a change in control of the Company, we do not have any agreements with our interim CEO or our CFO that provide for “single trigger” change in control equity vesting acceleration benefits.

•None of our Named Executive Officers is entitled to a “gross up” of any income or excise taxes.

•We maintain a clawback policy with respect to incentive compensation as described in more detail below.

•We maintain a stock ownership policy that subjects our Named Executive Officers and members of our Board of Directors to specified holding requirements.

•Our Named Executive Officers and members of our Board of Directors are prohibited from engaging in hedging transactions and pledging transactions with respect to Company securities.

Objectives of the Company’s Executive Compensation Program

The Company’s executive compensation program is designed to:

•attract, motivate, reward and retain highly qualified and talented individuals,

•motivate executives to improve the overall performance and profitability of the Company and reward them when specific measurable results have been achieved,

•encourage accountability by making executive compensation decisions based on Company performance as well as each executive’s individual performance and contributions,

•tie incentive awards to performance metrics that we believe drive the performance of the Company’s Common Stock over the long term to further reinforce the linkage between the interests of the Company’s shareholders and employees,

•link executives’ interests with shareholders’ interests by generally providing a significant portion of targeted total direct compensation in the form of stock-based incentives, and

•ensure compensation levels are both externally competitive and internally equitable.

Listening to Our Shareholders

Each year, we provide our shareholders the opportunity to cast an advisory vote on our executive compensation program. This annual vote is known as the “say-on-pay” proposal. At the Company’s 2024 Annual Meeting of Shareholders held on March 15, 2024, approximately 78.5% of the votes cast on the say-on-pay proposal were voted in favor of the proposal, while at the Company’s 2023 Annual Meeting of Shareholders, approximately 81.6% of the votes cast on the say-on-pay proposal were voted in favor of the proposal, and at the Company’s 2022 Annual Meeting of Shareholders, approximately 94.0% of the votes cast on the say-on-pay proposal were voted in favor of the proposal. The Compensation Committee believes the high degree of support for our say-on-pay proposals reflects shareholders’ approval of the significant changes we made to our executive compensation program during the fiscal year ended September 30, 2016 (“fiscal 2016”) and that have been maintained through fiscal 2024.

We have continued to meet with a significant portion of our institutional shareholders who each individually hold more than 0.5% of our outstanding shares. In general, our shareholders have continued to react positively to our executive compensation and corporate governance practices. Our executive compensation programs have strong governance components that further strengthen our pay-for-performance compensation philosophy, including the following:

Table of Contents


Compensation Practice			Our Policies and Actions
Short-Term Incentive Plan			100% of each Named Executive Officer’s cash bonus opportunity for fiscal 2024 was tied to at least one Company performance metric.
Minimum Vesting Period for Equity Awards			The Company’s 2019 Equity Incentive Plan requires substantially all awards granted under the 2019 Equity Incentive Plan to have a minimum vesting period of one year and, subject to the Compensation Committee’s discretion to accelerate awards, prohibits any portion of an award to vest earlier than the first anniversary of the grant date of the award.
Limited Discretion to Accelerate Vesting on Change in Control			The 2019 Equity Incentive Plan limits the Compensation Committee’s discretion to accelerate awards upon the consummation of a change in control.
Clawback Policy			We maintain a clawback policy that applies to all of our executive officers.
Stock Ownership Policy			We maintain a stock ownership policy with a 3x salary ownership requirement for our Chief Executive Officer and a 1x salary ownership requirement for other Named Executive Officers. Executive officers are required to retain at least 50% of the net after-tax shares received in respect of equity awards until they are in compliance.
Restrictions on Hedging and Pledging Transactions			We maintain a policy prohibiting pledging or hedging of the Company’s securities or engaging in derivative transactions related to our Common Stock.
Independent Compensation Committee			Our Compensation Committee consists entirely of independent directors.
Independent Compensation Consultant			Our Compensation Committee utilizes an independent compensation consultant, which is retained directly by the Compensation Committee and provides no other services to the Company’s management.

Role of the Compensation Committee

Pursuant to its charter, the Compensation Committee has the authority to determine the compensation of our Named Executive Officers. The Compensation Committee approves the structure of our executive compensation program, and is responsible for administering our equity compensation plans, including approving grants of awards under the plans. In performing its duties, the Compensation Committee is authorized to consider the recommendations of our Chief Executive Officer when determining the compensation of the other Named Executive Officers.

The elements of our executive compensation program and the compensation amounts payable thereunder to each Named Executive Officer were approved by the Compensation Committee. All Compensation Committee members are independent under applicable Nasdaq rules, and, except for recommendations made by Mr. Vargas with respect to the compensation of the other Named Executive Officers (other than himself), no Named Executive Officers had any role in determining the compensation of the Named Executive Officers.

Compensation Risk

The Compensation Committee has reviewed the Company’s compensation policies and practices for all employees, including executive and non-executive officers, and determined that the Company’s compensation programs do not give rise to risks reasonably likely to have a material adverse effect on the Company. The Compensation Committee noted several design features of the Company’s cash and equity incentive programs for executive officers in particular that reduce the likelihood of excessive risk-taking and instead encourage behaviors that support sustainable value creation by rewarding employees for achieving long-term financial and strategic objectives through prudent business judgment and appropriate risk taking. Some of these elements include:

•A Balanced Mix of Compensation Components. The program design provides a balanced mix of cash and equity, annual and longer-term incentives, and performance metrics.

Table of Contents

•Multiple Performance Factors. Our incentive compensation plans use company-wide performance metric(s), which in fiscal 2024 was our free cash flow for fiscal 2024 and cash balance as of September 30, 2024, and, in the case of certain non-executive employees, individual performance goals related to specific strategic or operational objectives. In addition, long-term incentive compensation in the form of PSUs is based on a combination of either (1) an increase in share price or (2) relative total shareholder return, which measures our performance against that of our competitors, and the executive’s continued employment with the Company.

•Focus on Long-term Incentives. Long-term incentive compensation is an integral part of compensation that discourages short-term risk taking. The long-term incentive grants for senior management are currently allocated between RSUs and PSUs, which provides a balance of incentives. Our long-term incentive awards generally are granted on an annual basis with long-term, overlapping vesting periods to motivate eligible recipients to focus on sustained stock price appreciation.

•Managed Expectations. Our cash and equity incentive plans contain a cap on the maximum payout to avoid targets that, if not achieved, result in an unduly large percentage loss of compensation.

•Stock ownership guidelines. Our stock ownership guidelines require that all of our executive officers hold a significant amount of our equity to align their interests with shareholders over the long term.

•Clawback policy. We have a compensation recovery (clawback) policy applicable in the event of an accounting restatement.

•Prohibition Against Short-term and Speculative. In an effort to avoid the potential for heightened legal risk or the appearance of improper or inappropriate conduct by our directors, executives and other employees, we prohibit all of our employees and directors from engaging in short-term trading of the Company’s securities, short sales, transactions in puts, calls or other derivative securities related to the Company’s stock on an exchange or in any other organized market, entering into hedging or monetization transactions that are designed to hedge or offset any decrease in the market value of the Company’s securities, margining Company securities held in a margin account, or pledging Company securities as collateral for a loan.

Role of Compensation Consultant

Pursuant to its charter, the Compensation Committee has the authority to engage its own advisors to assist in carrying out its responsibilities. Since 2016, the Compensation Committee has retained Compensia, a national compensation consulting firm, to advise it regarding the amount and types of compensation that we provide to our executive officers, including our Named Executive Officers, and how our compensation practices compare to the compensation practices of other companies. The members of the Compensation Committee consider input from Compensia as one factor in making decisions with respect to executive compensation matters, along with information and analysis they receive from management and their own judgment and experience.

The Compensation Committee regularly reviews the services provided by Compensia and performs an assessment at least annually on the independence of Compensia to determine whether the compensation consultant is independent. For fiscal 2024, the Compensation Committee determined that Compensia is independent in providing the Compensation Committee with executive compensation consulting services and that Compensia’s work for the Compensation Committee did not raise any conflicts of interest, consistent with SEC rules and Nasdaq listing standards. Compensia did not perform any services for the Company during fiscal 2024 other than providing advice with respect to executive officer and director compensation.

Peer Companies

The composition of the Company’s peer group of companies is reviewed annually to ensure that the selected peer companies are appropriate in terms of industry, company size and business focus. As done in prior years, in October 2023, the Compensation Committee engaged Compensia to conduct a review of the Company’s peer group of companies, as well as a comprehensive compensation survey utilizing the new peer group for each of our Named Executive Officers.

After assessing the 2023 peer group of companies, based on the recommendation of Compensia, the Compensation Committee removed and replaced certain companies previously selected as peer group companies to establish the following peer group:

Table of Contents


October 2022 Peer Group:			New October 2023 Peer Group:
•AeroVironment, Inc. •Airgain, Inc. •Applied Optoelectronics, Inc. •Astronics Corporation •Aviat Networks, Inc. •DZS, Inc. •Gilat Satellite Networks Ltd. •inTEST Corporation •Intevac, Inc. •KVH Industries, Inc. •Luna Innovations Incorporated •nLIGHT, Inc. •Park Aerospace Corp. •Ultralife Corporation			•Air Industries Group •Airgain, Inc. •Astronics Corporation •Butler National •CPI Aerostructures •DZS, Inc. •Innovative Solutions and Support •inTEST Corporation •Intevac, Inc. •Intuitive Machines •KVH Industries, Inc. •Luna Innovations Incorporated •nLIGHT, Inc. •Park Aerospace Corp. •SIFCO Industries •TAT Technologies •Ultralife Corporation

In October 2023, in connection with compensation decisions related to fiscal 2024, Compensia reviewed the compensation levels for each of the Named Executive Officers, utilizing the Company’s new October 2023 peer group with respect to Mr. Rittichier and a blend of the Company’s new October 2023 peer group and broader survey data with respect to Mr. Minichiello. The analysis covered base salary, target bonus as a percent of salary, target total cash compensation, total long-term incentive compensation value and target total direct compensation relative to each company in the October 2023 peer group (or a blend of the Company’s new October 2023 peer group and broader survey data with respect to Mr. Minichiello). Following review of Compensia’s analysis, the Compensation Committee made a determination in December 2023, in light of the Company’s then-recent financial performance and then-current liquidity situation, to make no changes to each Named Executive Officer’s base salary or target bonus percentage for fiscal 2024 from the amounts previously approved by the Committee in March 2022.

The purpose of the compensation review was to provide the Compensation Committee with information on the compensation practices and program designs at peer companies. This information is used by the Compensation Committee to inform its decision-making process with respect to the compensation amounts for the Named Executive Officers. However, the Compensation Committee does not rigidly adhere to a benchmarking strategy in setting compensation amounts for the Named Executive Officers. Instead, the peer group compensation information is used as one of the data points for the Compensation Committee to make subjective compensation decisions using its business judgment after considering a number of factors, including our objectives of attracting and motivating highly qualified executives, holding executives accountable and rewarding them for individual performance, and ensuring that compensation levels are externally competitive and internally equitable.

Base Salary

Base salaries for the Named Executive Officers are determined based upon job responsibilities, level of experience, individual performance, and the peer group compensation information described above. None of our Named Executive Officers is entitled to an automatic base salary increase, and all increases in base salary for our Named Executive Officers are determined by the Compensation Committee in its discretion. The Compensation Committee reviews any proposed base salary increase for our Chief Executive Officer in executive session without Company management present.

During fiscal 2024, Mr. Vargas’s base salary was initially $210,000, was increased to $270,000 in January 2024 and then was increased to $375,000 in May 2024 in connection with his appointment as the Company’s interim CEO. During fiscal 2024, Mr. Minichiello’s base salary was $365,000, Mr. Black’s base salary was $300,000 (through his separation from service with the Company effective February 16, 2024) and Mr. Rittichier’s base salary was $500,000 (through his separation from service with the Company effective May 7, 2024).

Short-Term Cash Incentives

In General. Historically, the Company established a new cash incentive plan each fiscal year which provided the Company’s executive officers an opportunity to receive an annual cash payment in addition to their base salaries. In place of an annual plan, on June 9, 2022, the Compensation Committee approved the EMCORE Corporation Short-Term Incentive Plan (the “Short-Term Incentive Plan”). The Short-Term Incentive Plan provides participants with an opportunity to earn cash bonus payments upon the satisfaction of performance goals for a specified performance period, generally the Company’s fiscal year, and generally subject to continued employment through the payment date.

Table of Contents

Under the Short-Term Incentive Plan, bonus payments, if any, are based on an individual target bonus amount for the performance period set by the Compensation Committee and are directly related to the satisfaction of the applicable performance goal(s) set by the Compensation Committee for such performance period. Performance goals may include one or more of the enumerated benchmarks set forth in the Short-Term Incentive Plan or such other criteria as determined by the Compensation Committee. Such performance goals may relate to the performance of the Company as a whole, a business unit, division, department, individual or any combination of these and may be applied on an absolute basis and/or relative to one or more peer group companies or indices, or any combination thereof, as determined by the Compensation Committee. The Short-Term Incentive Plan provides that the maximum bonus payable to any participant for any fiscal year is 150% of the applicable participant’s base salary for such period or such lower amount as determined by the Compensation Committee. Any bonus payments earned under the Short-Term Incentive Plan will be paid as soon as administratively practicable after the end of the applicable performance period, subject to the employee’s continued employment through the payment date.

The Short-Term Incentive Plan contains baseline good governance features – bonus payments are tied to performance metrics and are subject to a hardwired cap rather than a cap determined each year (and the 2024 annual bonus cap was 100% of the applicable participant’s base salary). The Short-Term Incentive Plan shall remain in effect until such time as the Compensation Committee or the Board of Directors suspends, modifies or terminates the Short-Term Incentive Plan.

Fiscal 2024 Performance Goals and Target Bonus Amounts. In January 2024, the Compensation Committee adopted financial goals under the Short-Term Incentive Plan for fiscal 2024 and established the following target bonus opportunities under the Short-Term Incentive Plan for each of our Named Executive Officers: 100% of Mr. Rittichier’s base salary, 75% of Mr. Minichiello’s base salary and 50% of Mr. Black’s base salary. In May 2024, in connection with his appointment as the Company’s interim CEO, the Compensation Committee established a target bonus opportunity under the Short-Term Incentive Plan of $187,500 (50% of his new base salary of $375,000) for Mr. Vargas. The Compensation Committee determined to cap bonus payouts for outperformance at 100% of the employee’s target bonus amount to limit our Named Executive Officers’ and non-executive employees’ maximum bonus potential for fiscal 2024.

For fiscal 2024, in consultation with its advisors, the Compensation Committee, consistent with and in support of the Company’s fiscal 2024 goals and objectives, established fiscal 2024 performance goals for Mr. Rittichier, Mr. Minichiello and Mr. Black related solely to the performance of the Company and the achievement of free cash flow and cash balance targets.

In May 2024, in connection with his appointment as the Company’s interim CEO, the Compensation Committee determined that Mr. Vargas’s cash bonus for fiscal 2024 would be based on the Company’s achievement of adjusted cash flow breakeven (excluding restructuring costs) by the end of the quarter ending September 30, 2024. The Compensation Committee established adjusted cash flow breakeven (excluding restructuring costs) by the end of the quarter ending September 30, 2024 as the Company performance goal with respect to Mr. Vargas because it believed this financial metric was the best indicator of the Company’s improved performance for the period of time that Mr. Vargas was expected to serve as interim CEO during fiscal 2024 and aligned with the Company’s then-current financial goals and liquidity status. In December 2024, the Committee determined that the Company had achieved adjusted cash flow breakeven (excluding restructuring costs) by the end of the quarter ending September 30, 2024 and approved the payment of Mr. Vargas’s cash bonus for fiscal 2024.

For fiscal 2024, for all employees other than our interim CEO, the Compensation Committee designated the achievement of free cash flow and cash balance targets as the Company performance goal for fiscal 2024 because it believed these metrics were the best indicator of the Company’s performance for fiscal 2024 in light of the Company’s efforts to generate cash from operations. The Compensation Committee also believed that these metrics properly incentivized Mr. Rittichier, Mr. Minichiello and Mr. Black to achieve objectives that would support these efforts. For purposes of awards payable under the Short-Term Incentive Plan with respect to fiscal 2024, “free cash flow” means adjusted EBITDA minus capital expenses and proceeds from financing activities and “adjusted EBITDA” means operating profit for the Company’s ongoing businesses as determined under generally accepted accounting principles in the United States, less interest expense, tax expense, depreciation and amortization and with adjustments approved by the Compensation Committee. For fiscal 2024, the Compensation Committee established the following free cash flow and cash balance targets and subsequently determined our actual performance levels as set forth below:


Company Performance Goal	Target:	Actual:	Target Achieved:
Free Cash Flow for fiscal 2024	-$(3.284) million	-$(5.697) million	No
Cash balance as of 9/30/24	$14.5 million	$10.8 million	No

Non-GAAP bookings are reconciled in accordance with GAAP and included in the consolidated financial statements set forth in this Annual Report. The Company failed to meet the free cash flow target for fiscal 2024 and the cash balance as of September 30, 2024 target, and in December 2024, the Committee determined that no amount would be payable to Mr. Minichiello or any non-executive employee under the Short-Term Incentive Plan for fiscal 2024 (except for the bonus payable to Mr. Vargas as described above).

Table of Contents

Sales Commission Plan. Mr. Vargas is also eligible to earn quarterly cash commission payments pursuant to the Company’s sales commission plan. Pursuant to such plan, commissions with respect to Mr. Vargas (in his capacity as the Company’s VP, Sales) are determined and earned based on (i) a percentage of the dollar value of the Company’s bookings in the applicable quarter and (ii) achievement of a bookings target on the first day of the applicable quarter as compared to the Company’s revenue target (based on the Company’s Board-approved operating plan) for the immediately preceding quarter. Any such commissions are paid quarterly, subject to Mr. Vargas’s continued service through the payment date. For fiscal year ended September 30, 2024, Mr. Vargas earned total sales commissions of $92,432 under the Company's sales commission plan.

Long-Term Stock-Based Incentives

In General. The Company believes that stock-based incentives are an effective means for aligning the interests of our executives with the interests of our shareholders and that the long-term compensation of the Company’s Named Executive Officers should be linked to the value provided to our shareholders. In addition, we use stock-based compensation as a retention tool. Because our stock-based awards generally vest over a multi-year period, they provide our executives with an ongoing incentive to continue their employment with the Company and to maximize shareholder value. Long-term stock-based incentives granted to our executives for the last several years have been structured in the form of restricted stock unit awards. Restricted stock unit (“RSU”) awards are designed to link executives’ interests with those of the Company’s shareholders, because the value of the awards is based on the value of our Common Stock. In addition, they provide a long-term retention incentive throughout the vesting period because the RSUs generally have value regardless of stock price volatility.

In granting equity awards to our Named Executive Officers, the Compensation Committee relied on the advice of our independent compensation consultant and used its judgment and discretion to determine the appropriate value of each award at the time it was granted (based on the value of our Common Stock when granted) and reviewed each executive’s individual performance and the performance of the Company in the prior fiscal year, as well as the peer group compensation information described above.

Fiscal 2024 Awards for Named Executive Officers. On June 15, 2024, after taking into account the advice of our independent compensation consultant, the Compensation Committee granted 215,517 RSUs with a grant date fair value of $185,345 to Mr. Vargas and 76,400 RSUs with a grant date fair value of $65,704 to Mr. Minichiello. The grant date fair value was computed based on the closing price of $0.86 per share of our Common Stock on June 14, 2024, the last trading day prior to the grant date. Mr. Vargas’s RSU award was granted pursuant to the amended and restated offer letter entered into between the Company and Mr. Vargas on May 8, 2024 in connection with his appointment as the Company’s interim CEO, and will vest in full on the first anniversary of the grant date, subject to his continued employment with the Company (in any capacity) through the vesting date. Mr. Minichiello’s RSUs will vest as to 33.3% of the underlying shares on each of the first three anniversaries of the grant date, subject to his continued employment with the Company through the vesting date. In determining the appropriate grant date value of the June 2024 RSU awards, the Compensation Committee considered the size of historical equity award grants made to other senior executives, the current retention hold for Mr. Vargas and Mr. Minichiello, the recommendations of our independent compensation consultant, and the peer group compensation information described above. Nevertheless, the number of shares underlying the RSU awards granted in June 2024 were, based on the grant date fair value, less than the annual equity grant values recommended by our independent compensation consultant and less than the grant date fair value of awards made in prior years. However, in determining the number of shares underlying the RSU awards granted in June 2024, the Compensation Committee balanced the need to incentivize and motivate our Named Executive Officers with the limited number of shares available under the Company’s equity plans. Neither Mr. Black nor Mr. Rittichier received an RSU or other equity award during fiscal 2024.

Outstanding Prior Fiscal Year PSUs. During fiscal 2024, our Named Executive Officers each held performance restricted stock units (“PSUs”) that were granted during fiscal 2023 and fiscal 2022. The PSUs that were granted during the fiscal year ended September 30, 2023 (“fiscal 2023”) will vest, if at all, based on a combination of our achievement of an average stock price per share of the Common Stock at the close of regular trading on the principal exchange on which the stock is listed or traded for any 30-calendar day period during a three-year performance period that averages more than 130% of the per share closing price on the PSU grant date, generally subject to the Named Executive Officer’s continued employment through the last day of the performance period. The PSUs currently outstanding that were granted during the fiscal year ended September 30, 2022 (“fiscal 2022”) will vest based on a combination of our relative total shareholder return over a three-year performance period following the grant date, generally subject to the executive’s continued employment through the last day of the performance period. Relative total shareholder return with respect to the fiscal 2022 PSUs is measured against the companies in the Russell 2000 Index.

Company Benefits

The Company’s benefits are an important tool in our ability to attract and retain outstanding employees throughout the Company. As a business matter, we weigh the benefits we need to offer to remain competitive and attract and retain talented

Table of Contents

employees against the cost of the benefits. Benefit levels are reviewed periodically to ensure they are cost-effective and competitive and support the overall needs of Company employees.

This section describes the benefits that the Company provides to key executives and notes those instances when benefits for the Named Executive Officers differ from the general plan. In some instances, we also describe the programs we offer across the Company as context to specific discussions about executive benefits.

Medical, Dental, and Vision Benefits

The Company offers a standard benefits package to all of its eligible employees, which includes medical, dental and vision coverage. The Named Executive Officers are also eligible to receive supplemental health benefit coverage that is not made available to non-executive employees, which provides the Named Executive Officers with additional Company-paid medical, dental and vision coverage that could be applied when their primary medical, dental or vision coverage has exceeded its coverage limit or does not provide coverage.

Company-Sponsored Retirement Plan

The EMCORE Corporation 401(k) Plan (the “401(k) Plan”) is a tax-qualified defined contribution plan that is designed to comply with the Employee Retirement Income Security Act of 1974, as well as federal and state legal requirements. The 401(k) Plan is designed to provide retirement benefits to eligible employees of the Company. Eligible employees, including the Company’s Named Executive Officers, may elect to contribute to the 401(k) Plan through salary reduction up to the yearly maximum tax-deductible deferral allowed pursuant to IRS regulations. A participant may elect to defer between 1-90% of his or her compensation per pay period. Each participant is able to direct his or her investment into any of the available investment options. Participants’ contributions are vested at 100%. The Company may provide a discretionary match of a participant’s contribution to the 401(k) Plan. During fiscal 2024, this discretionary match was 100% of the first 3% of a participant’s contribution to the 401(k) Plan plus 50% of the next 2% of a participant’s contribution to the 401(k) Plan, subject to certain IRS limits, with such matching contributions vesting immediately.

Officer and Director Share Purchase Plan

In January 2011, the Compensation Committee approved an Officer and Director Share Purchase Plan (the “ODPP”), which allows executive officers, including the Named Executive Officers, and directors of the Company to purchase shares of Common Stock at fair market value in lieu of salary or, in the case of directors, director fees. Eligible individuals may voluntarily participate in the ODPP by authorizing payroll deductions or, in the case of directors, deductions from director fees for the purpose of purchasing shares of Common Stock. Elections to participate in the ODPP may only be made during open trading windows under the Company’s insider trading policy and when the participant does not otherwise possess material non-public information concerning the Company.

Perquisites and Other Personal Benefits

We generally do not provide our executive officers, including the Named Executive Officers, with perquisites or other personal benefits, except for supplemental health benefit coverage (as described above under “Medical, Dental, and Vision Benefits”), and, in the case of our CFO, reimbursement of certain modest commuting expenses, including airfare, ground transportation, lodging and meals, related to Mr. Minichiello’s travel to and from his home and the Company’s headquarters. These items are provided because we believe that they serve a necessary business purpose and represent an immaterial element of our executive compensation program. We do not provide tax reimbursements or any other tax payments with respect to perquisites, including excise tax “gross-ups,” to any of our executive officers.

Severance Benefits

In an effort to further promote the retention of the Company’s Named Executive Officers, the Company previously entered into (1) an executive severance and change in control agreement with each of Mr. Vargas and Mr. Black in May 2023, (2) an executive employment agreement with Mr. Minichiello in connection with his appointment as our Chief Financial Officer effective August 26, 2019 and (3) an executive employment agreement with Mr. Rittichier in connection with his appointment as our Chief Executive Officer effective January 3, 2015. These agreements set forth each executive’s eligibility for severance benefits upon a qualifying termination by us without “cause” or by the executive for “good reason” (as those terms are defined in each executive’s executive severance and change in control agreement or employment agreement, as applicable). We do not believe that the Named Executive Officers should be entitled to receive cash severance benefits merely because a change in control transaction occurs in the absence of a termination of employment, accordingly, a change in control does not, in and of itself, entitle any Named Executive Officer to receive cash severance benefits.

Clawback Policy

We have long maintained a compensation recoupment policy. Effective as of October 2, 2023, we adopted a clawback policy that provides for the recoupment of excess incentive compensation paid to executive officers, including the Named Executive Officers, in the event of an accounting restatement due to material noncompliance with financial reporting requirements in accordance with NASDAQ listing standards and Exchange Act Rule 10D-1. The policy applies to compensation that is granted, earned, or vested based in whole or in part upon the attainment of a financial reporting measure and provides for the reimbursement or forfeiture by the executive officer of the excess portion of the compensation received by the executive officers during the three preceding fiscal years.

Stock Ownership and Holding Requirements

We maintain a stock ownership policy. We believe that this policy aligns the interests of our executive officers with those of our shareholders by requiring executive officers to have direct ownership in shares of our Common Stock. The policy requires our Chief Executive Officer to own shares of our Common Stock having a value equal to at least three times his or her annual base salary and our other executive officers to own shares of our Common Stock having a value equal to at least one times his or her annual base salary. Shares subject to stock options and unvested stock unit awards are not considered owned by the executive for purposes of the policy. The executives covered by the policy are required to be in compliance with the ownership levels above within five years after the date such person is appointed as an executive officer and are required to retain at least 50% of the net after-tax shares received in respect of equity awards until they are in compliance.

Anti-Hedging, Pledging and Derivatives Policy

The Company considers it improper and inappropriate for the Company’s directors, executive officers and other employees to engage in short-term or speculative transactions in the Company’s securities and other transactions in the Company’s securities that create the potential for heightened legal risk or the appearance of improper or inappropriate conduct even if they occur at a time when the individual is not aware of material nonpublic information. Accordingly, the Company prohibits these individuals from engaging in short-term trading of the Company’s securities, short sales, transactions in puts, calls, or other derivative securities related to the Company’s stock on an exchange or in any other organized market, entering into hedging or monetization transactions that are designed to hedge or offset any decrease in the market value of the Company’s securities, margining Company securities held in a margin account, or pledging Company securities as collateral for a loan.

Tax and Accounting Considerations

Section 162(m) of the Internal Revenue Code generally disallows a tax deduction to public companies for compensation in excess of $1 million paid to a company’s chief executive officer and certain current and former executive officers. The Compensation Committee considers, among other relevant factors, the deductibility of compensation when it reviews our

compensation plans and policies. However, there can be no assurance that any compensation will, in fact, be deductible, and the Compensation Committee may award non-deductible compensation when it determines it to be appropriate.

EXECUTIVE COMPENSATION

The table below sets forth certain information concerning the compensation paid to or earned by those persons who during fiscal 2024 served as interim CEO, CFO, former SVP, Operations, and former CEO. Our CFO and our former SVP, Operations were our two most highly compensated executive officers during fiscal 2024 other than our interim CEO, and our former CEO. Because we qualify as a “smaller reporting company,” compensation information is provided for the two most recently completed fiscal years ended September 30, 2024 and 2023.

Potential Payments upon Termination or Change-in-Control

In an effort to further promote the retention of Messrs. Vargas, Minichiello, Black and Rittichier, the Compensation Committee previously approved (1) an executive severance and change in control agreement with Mr. Vargas effective May 17, 2023 (the “Vargas Severance Agreement”), (2) an executive employment agreement with Mr. Minichiello in connection with his appointment as our Chief Financial Officer effective August 26, 2019 (the “Minichiello Employment Agreement”), (3) an executive severance and change in control agreement with Mr. Black effective May 17, 2023 (the “Black Severance Agreement”) and (4) an executive employment agreement with Mr. Rittichier in connection with his appointment as our Chief Executive Officer effective January 3, 2015 (the “Rittichier Employment Agreement”), each of which provide for certain severance benefits.

The Vargas Severance Agreement and the Minichiello Employment Agreement

The Vargas Severance Agreement and the Minichiello Employment Agreement each provide that the respective Named Executive Officer’s employment is “at-will” and may be terminated by Mr. Vargas or Mr. Minichiello, as applicable, or by the Company at any time with or without cause, subject only to the severance obligations set forth in such agreements. The Vargas Severance Agreement and the Minichiello Employment Agreement each provide for certain severance benefits upon termination without “cause” by the Company or termination for “good reason” by such Named Executive Officer, subject to the Named Executive Officer entering into a general release agreement with the Company and compliance with certain confidentiality, nondisclosure, and other restrictive covenants. The severance benefits under such arrangements that will be paid upon such terminations of employment, regardless of whether a “change in control” occurs, are:

Table of Contents

•Continued payment of the Named Executive Officer’s current base salary for six months for Mr. Vargas and twelve months for Mr. Minichiello;

•Subject to the executive officer’s timely election to continue existing health benefits under COBRA, payment of all or a portion of the executive officer’s COBRA premiums for the same period as such executive officer’s base salary is continued; and

•For Mr. Minichiello only, payment of his target annual bonus for the fiscal year of such termination.

In addition to the benefits described above:

•If Mr. Vargas’s employment is terminated by the Company without “cause” or he terminates his employment for “good reason” within three months prior to or twelve months following a “change in control”, he is also entitled to receive (1) an amount equal to his prorated target annual bonus for the fiscal year of such termination, payable over six months, and (2) acceleration and immediate vesting of all of his outstanding equity awards that vest based solely on services over time (with any awards subject to performance-based vesting requirements subject to vesting on the terms set forth in the applicable agreement governing such award); and

•If Mr. Minichiello’s employment is terminated by the Company without “cause” or he terminates his employment for “good reason” within twelve months following a “change in control”, he is also entitled to acceleration and immediate vesting of all of his outstanding equity awards (with any awards subject to performance-based vesting requirements vesting at a minimum of the target performance level).

The base salary of each of Mr. Vargas and Mr. Minichiello will continue to be determined annually by the Compensation Committee, which may, in its sole and absolute discretion, increase Mr. Vargas’s or Mr. Minichiello’s base salary, but, with limited exception, may not decrease it below Mr. Vargas’s or Mr. Minichiello’s initial base salary without Mr. Vargas’s or Mr. Minichiello’s consent, as applicable, provided that if, at any time, Mr. Vargas is not selected to become the Company’s Chief Executive Officer following his interim role, Mr. Vargas’s base salary will automatically revert to $270,000, his previous base salary in connection with his role as the Company’s VP, Sales immediately prior to his appointment as our interim CEO without Mr. Vargas’s consent and without triggering Mr. Vargas’s right to resign for “good reason”.

In the event a payment or benefit provided under the Vargas Severance Agreement or the Minichiello Employment Agreement would constitute a “parachute payment” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”), then such payment or benefit will be limited as provided in the applicable agreement. Neither of the Vargas Severance Agreement or the Minichiello Employment Agreement provide for any tax “gross up” or similar payment for any excise taxes that may be triggered by the payment of any parachute payments.

The following are estimated payments and benefits that would be provided to each of Mr. Vargas and Mr. Minichiello in the event the Named Executive Officer’s employment is terminated as described above. In accordance with applicable SEC disclosure rules, the estimates assume a termination date of September 30, 2024, the last business day of fiscal 2024. The actual amounts of the payments and costs of the benefits, however, can only be determined at the time of an executive’s separation from the Company.


Name	Cash Severance ($)	Continued Health Coverage (Company Part Only) ($)
Matthew Vargas...................................................................	187,500	18,407
Tom Minichiello...................................................................	638,750	17,238

In addition, as of September 30, 2024, Mr. Vargas and Mr. Minichiello would realize the following gains from the acceleration of unvested equity awards under the circumstances described above, measured based on a stock price of $2.21, which was the per share closing price of the Common Stock on the Nasdaq Global Market on September 30, 2024, the last trading day of fiscal 2024, assuming a change in control occurred on September 30, 2024, and assuming the acceleration and payout of PSUs based on a share price of $2.21 upon consummation of the change in control transaction:

•Matthew Vargas: $481,574 upon a qualifying termination within three months prior to or twelve months following a change in control; and

•Tom Minichiello: $203,822 upon a qualifying termination within twelve months following a change in control.

If Mr. Vargas’s or Mr. Minichiello’s employment is terminated for cause or such Named Executive Officer terminates his employment without good reason or due to death or disability, the Company will pay the Named Executive Officer’s base salary through the effective date of his termination and will not have any additional obligations to the Named Executive Officer.

ITEM 13. Certain Relationships and Related Transactions, and Director Independence.

Certain Relationships and Related Party Transactions

Since October 1, 2022, there has not been any transaction or series of similar transactions to which we were or are a party in which the amount involved exceeded or exceeds the lesser of $120,000 or one percent of the average of our total assets at year-end for the last two completed fiscal years, and in which any of our directors or executive officers, any holder of more than 5% of any class of our voting securities or any member of the immediate family of any of the foregoing persons had or will have a direct or indirect material interest.

Related Person Transaction Approval Policy

The Company’s Code of Business Conduct and Ethics sets forth the Company’s written policy for the review and approval of related person transactions. A related person is defined by applicable SEC rules as any executive officer, director or director nominee, any person who is known to be a beneficial owner of more than five percent (5%) of the voting securities of the Company, and any immediate family member of any of the foregoing persons.

A related person transaction is defined under applicable SEC rules as any financial or other transaction, arrangement or relationship (including any indebtedness or guarantee of indebtedness) or any series of similar transactions, arrangements or relationships in which the Company (or a subsidiary) would be a participant and the amount involved would exceed the lesser of $120,000 and 1% of the average of the Company’s total assets at year-end for the last two completed fiscal years, and in which any related person would have a direct or indirect material interest. A related person will not be deemed to have a direct or indirect material interest in a transaction if the interest arises only from the position of the person as a director of another corporation or organization that is a party to the transaction or the direct or indirect ownership by such person and all the related persons, in the aggregate, of less than ten percent (10%) of the equity interest in another person (other than a partnership) which is a party to the transaction. In addition, certain interests and transactions, such as director compensation that has been approved by the Board of Directors, transactions where the rates or charges are determined by competitive bid and compensatory arrangements solely related to employment with the Company (or a subsidiary) that have been approved by the Compensation Committee, are not subject to the policy.

The Board of Directors has delegated to the Audit Committee the responsibility for reviewing, approving and, where applicable, ratifying material related person transactions involving the Company’s directors or executive officers or their respective immediate family members or affiliated entities. If a member of the Audit Committee has an interest in a related person transaction, then he or she will not participate in the review process.

102

Table of Contents

In considering the appropriate action to be taken regarding a related person transaction, the Audit Committee or the Board of Directors (as the case may be) will consider the best interests of the Company, whether the transaction is fair to the Company and serves a compelling business reason, and any other factors that it deems relevant. As a condition to approving or ratifying any related person transaction, the Audit Committee may impose whatever conditions and standards it deems appropriate, including periodic monitoring of ongoing transactions.

The Company’s Code of Business Conduct and Ethics also includes the Company’s Conflicts of Interest Policy, among other policies. The Conflicts of Interest Policy provides, among other things, that conflicts of interest exist where the interests or benefits of one person or entity conflict with the interests or benefits of the Company. The Code of Business Conduct and Ethics also provides restrictions on outside directorships, business interests and employment, and receipt of gifts and entertainment and requires that all material violations of the Company’s Code of Business Conduct and Ethics or matters involving financial or legal misconduct be reported to the Audit Committee on at least a quarterly basis, or more frequently depending upon the level of severity of the violation.

Directors and executive officers are also required to disclose potential and existing related person transactions on a quarterly basis and in Directors and Officers Questionnaires completed annually.

Director Independence

The Board of Directors reviews the independence, and any possible conflicts of interest, of directors and director nominees at least annually. The Board of Directors has affirmatively determined that each of Mr. Glasener, Mr. Grooms, Mr. Rogers and Mr. Roncka are independent under the listing standards applicable to the Company pursuant to the Nasdaq rules, comprising a supermajority (80%) of the Board of Directors. Mr. Vargas, as the Company’s Interim Chief Executive Officer, is not independent under the Nasdaq rules.

In addition to the Nasdaq listing standard rules, the Company’s Amended and Restated Bylaws require that a majority of the Board of Directors be independent pursuant to certain additional criteria that, in many cases, are not included within the requirements of the Nasdaq rules. For example, a director is not considered independent for purposes of the Amended and Restated Bylaws if, in the past three years, the director or any of his or her family members: (i) has received any remuneration as an advisor, consultant or legal advisor to the Company or any of its subsidiaries, affiliates, executive officers or to any other director of the Company; (ii) has an agreement with the Company or any of its subsidiaries or affiliates for personal services or has engaged in any transaction or business relationship with the Company or its subsidiaries or affiliates; or (iii) is affiliated with or employed by any present or former auditor for the Company. The Board of Directors has determined that each of Messrs. Glasener, Grooms, Rogers and Roncka are also independent directors within the meaning of the Company’s Amended and Restated Bylaws. A copy of the Company’s Amended and Restated Bylaws is posted in the Governance section on the Investors tab of the Company’s website (www.emcore.com).

In making its independence determination, the Board of Directors considers the responses of each director and executive officer to an annual Directors and Officers Questionnaire, in which each director answers specific questions to facilitate an evaluation of the director’s independence and each director and executive officer discloses, among other things, information about the following: his or her employment or other occupation; service on the boards or committees of other companies (both public and private); service as a director, trustee or executive officer in any charitable organizations; service of a family member as an officer in any company (public or private) or charitable organizations; relationships by blood, marriage or adoption among directors or executive officers of the Company; related person transactions with the Company; legal proceedings involving the Company; indebtedness to the Company; or prior arrangements and understandings with respect to the selection of directors or executive officers of the Company. Following a review of these questionnaires, the Company did not identify any transactions, relationships or arrangements engaged in by these directors or in which they participated (directly or indirectly) to be considered by the Board of Directors in making its independence determination.

In addition, the Audit Committee may also pre-approve particular services on a case-by-case basis. For each proposed service, the independent auditors are required to provide detailed back-up documentation at the time of approval.

1 EMCORE CORPORATION DIRECTORS’ COMPENSATION POLICY (Amended Effective as of October 1, 2024) Directors of EMCORE Corporation (the “Company”) who are not employed by the Company or one of its subsidiaries (“non-employee directors”) are entitled to the compensation set forth below for their service as a member of the Board of Directors (the “Board”) of the Company. This policy shall remain in effect until it is revised or rescinded by further action of the Board or the Compensation Committee thereof. The Board has the right to amend this policy from time to time. The terms and conditions of this policy shall supersede any prior cash or equity compensation arrangements between the Company and its non-employee directors. Cash Compensation Annual Cash Retainer Annual Cash Retainer $50,000 Additional Committee Chairperson Retainer Annual Audit Committee Chairperson Retainer $20,000 Annual Compensation Committee Chairperson Retainer $9,500 Annual Nominating Committee Chairperson Retainer $8,000 Annual Strategy and Alternatives Committee Chairperson Retainer $30,000 Additional Committee Member Retainer Annual Audit Committee Member Retainer $10,000 Annual Compensation Committee Member Retainer $5,000 Annual Nominating Committee Member Retainer $3,000 Annual Strategy and Alternatives Committee Member Retainer $3,000 Equity Compensation Annual Equity Award Value $75,000 Additional Annual Chairperson Equity Award Value $42,500 Cash Compensation Each non-employee director will be entitled to an annual cash retainer while serving on the Board in the amount set forth above (the “Annual Cash Retainer”). Each non-employee director who serves as the Chairperson of the Audit Committee, the Compensation Committee, the Nominating Committee or the Strategy and Alternatives Committee of the Board will be entitled to an additional cash retainer while serving in that position in the applicable amount set forth above (an “Additional Committee Chairperson Retainer”). Each non-employee director who serves as a member of the Audit Committee, the Compensation Committee, the Nominating Committee or the Strategy and Alternatives Committee of the Board (but is not the chairperson of such Board committee) will be entitled to an additional cash retainer while serving in that position in the applicable amount set forth above (an “Additional Committee Member Retainer”). The amounts of the Annual Cash Retainer, Additional Committee Chairperson Retainer and Additional Committee Member Retainer (collectively, the “Cash Retainer”) reflected above are expressed as annualized amounts.. The Cash Retainer will be payable in equal quarterly installments in advance (each such quarterly payment, a “Quarterly Cash Retainer Payment”), with 25% of the Cash Retainer payable within five (5) business days of the first day of each fiscal quarter (the “Quarterly Retainer Payment Date”). If a non-employee director is elected or appointed to serve as a member of the Board following the date of the annual meeting of the Company’s shareholders for the applicable year and after the first day of the applicable quarter, his or her Quarterly Cash Retainer Payment for such quarter will be prorated by multiplying such Quarterly Cash Retainer Payment by a fraction, the numerator of which is the number of days from the appointment or election date to the last day of the applicable fiscal quarter, and the denominator of which is the number of calendar days in the applicable quarter (“Prorated Quarterly Cash Retainer Payment”). For the avoidance of doubt, a non- employee director who changes roles and is appointed to serve as a member of a committee or as a chairperson of a committee or the Board during any quarter following the Quarterly Retainer Payment Date for such quarter will be

2 entitled to a proration of the incremental increase, if any, between his or her Quarterly Cash Retainer Payment received for such quarter and the increased Quarterly Cash Retainer Payment amount. The Prorated Quarterly Cash Retainer Payment shall be paid to the non-employee director as soon as administratively practicable following such appointment or election. No Cash Retainer or Quarterly Cash Retainer Payments will be paid to the non-employee director for any period prior to the time that the non-employee director is elected or appointed to serve as a member of the Board. If a non-employee director’s service as a member of the Board is terminated due to the non-employee director’s voluntary resignation (which, for the avoidance of doubt, shall not include termination due to the non- employee director’s death or termination of service on the Board due to Disability (as defined under the Equity Plan) or as a result of a Change in Control (as defined under the Equity Plan)) (“Voluntary Resignation”), such non- employee director will be required to repay to the Company a prorated portion of the Quarterly Cash Retainer Payment attributable to any portion of the quarter for which services will not be rendered (with the proration based on the number of calendar days in the quarter that the non-employee director served as a non-employee director or held the particular position, as the case may be). If a non-employee director’s service as a chairperson or member of a committee is terminated due to the non-employee director’s Voluntary Resignation from such position but such non-employee director remains a member of the Board, any portion of the Additional Committee Chairperson Retainer or the Additional Committee Member Retainer, as applicable, that has been paid and is attributable to any portion of the quarter for which services as a chairperson or member of a committee, as applicable, will not be rendered will be netted against any Quarterly Cash Retainer Payment payable to the non-employee director for the subsequent quarter (with the proration based on the number of calendar days in the quarter that the non-employee director served as a chairperson or member of a committee, as the case may be). For the avoidance of doubt, a non- employee director who changes roles or whose service as a member of the Board or as a chairperson or member of a committee is terminated due to the non-employee director’s death or Disability (as defined under the Equity Plan) or as a result of a Change in Control (as defined under the Equity Plan) shall not be required to pay any portion of the Quarterly Cash Retainer Payment already paid to such non-employee director. The Board or the Compensation Committee may also approve other cash compensation in addition to or in lieu of the cash compensation described in this policy. Equity Compensation Annual Equity Award Beginning with the 2024 annual meeting of the Company’s shareholders, on the later of (a) the date of each annual meeting of the Company’s shareholders or (b) the date that there exists sufficient shares available for issuance under the Company’s Equity Plan and Certificate of Incorporation and such shares have been duly registered on a registration statement with the Securities and Exchange Commission, each non-employee director serving as a director immediately following such annual meeting will automatically be granted an award of restricted stock units (an “Annual Equity Award”) with the number of restricted stock units subject to such award determined by dividing (1) the Annual Equity Award grant value set forth above by (2) the per-share closing price of the Company’s common stock on the date of grant (rounded down to the nearest whole unit). For each new non-employee director appointed or elected to the Board other than on the date of an annual meeting of the Company’s shareholders, on the later of (a) the date that the new non-employee director first becomes a member of the Board or (b) the date that there exists sufficient shares available for issuance under the Company’s Equity Plan and Certificate of Incorporation and such shares have been duly registered on a registration statement with the Securities and Exchange Commission, the new non-employee director will automatically be granted a pro-rata portion of the Annual Equity Award (a “Pro-Rata Annual Equity Award”) with the number of restricted stock units subject to such award determined by dividing (1) a pro-rata portion of the Annual Equity Award grant value set forth above by (2) the per-share closing price of the Company’s common stock on the date of grant (rounded down to the nearest whole unit). The pro-rata portion of the Annual Equity Award grant value for purposes of a Pro-Rata Annual Equity Award will equal the Annual Equity Award grant value set forth above multiplied by a fraction (not greater than one), the numerator of which is 12 minus the number of whole months that as of the particular grant date had elapsed since the Company’s last annual meeting of shareholders at which Annual Equity Awards were granted by the Company to non-employee directors, and the denominator of which is 12.

3 Each Annual Equity Award and each Pro-Rata Annual Equity Award will vest in full on the earlier of (a) the first anniversary of the grant date, (b) the next annual meeting of the Company’s shareholders following the date of grant, (c) the consummation of a Change in Control (as defined in the Plan) or (d) the non-employee director’s death or termination of service on the Board due to Disability (as defined under the Equity Plan), subject to the non- employee director’s continued service on the Board through such vesting date. Additional Annual Chairperson Equity Award Beginning with the 2024 annual meeting of the Company’s shareholders, on the later of (a) the date of each annual meeting of the Company’s shareholders or (b) the date that there exists sufficient shares available for issuance under the Company’s Equity Plan and Certificate of Incorporation and such shares have been duly registered on a registration statement with the Securities and Exchange Commission, each non-employee director then serving as the Chairperson of the Board immediately following such annual meeting will automatically be granted an award of restricted stock units (an “Additional Annual Chairperson Equity Award”) with the number of restricted stock units subject to such award determined by dividing (1) the Additional Annual Chairperson Equity Award grant value set forth above by (2) the per-share closing price of the Company’s common stock on the date of grant (rounded down to the nearest whole unit). Each Additional Annual Chairperson Equity Award will vest in full on the earlier of (w) the first anniversary of the grant date, (x) the next annual meeting of the Company’s shareholders following the date of grant, (y) the consummation of a Change in Control (as defined in the Plan) or (z) the non-employee director’s death or termination of service on the Board due to Disability (as defined under the Equity Plan), subject to the non-employee director’s continued service on the Board through such vesting date; provided, however that a non-employee director that ceases to serve as Chairperson after the date of the last annual meeting of shareholders and prior to the first anniversary of such meeting date (but remains a non-employee director of the Board) shall be entitled to vest in a pro-rata portion of any outstanding Additional Annual Chairperson Equity Award determined by multiplying (1) the number of restricted stock units subject to such Additional Annual Chairperson Equity Award by (2) a fraction (not greater than one), the numerator of which is the number of whole months that as of such date have elapsed since the Company’s last annual meeting of shareholders at which the Additional Annual Chairperson Equity Award was granted by the Company to the Chairperson of the Board and the denominator of which is 12 (rounded down to the nearest whole unit). For a non-employee director that is newly appointed to serve as Chairperson of the Board other than on the date of an annual meeting of the Company’s shareholders, on the later of (a) the date that the new non-employee director first becomes Chairperson or (b) the date that there exists sufficient shares available for issuance under the Company’s Equity Plan and Certificate of Incorporation and such shares have been duly registered on a registration statement with the Securities and Exchange Commission, the new Chairperson of the Board will automatically be granted a pro-rata portion of the Additional Annual Chairperson Equity Award (a “Pro-Rata Additional Annual Chairperson Equity Award”) with the number of restricted stock units subject to such award determined by dividing (1) a pro-rata portion of the Additional Annual Chairperson Equity Award grant value set forth above by (2) the per- share closing price of the Company’s common stock on the date of grant (rounded down to the nearest whole unit). The pro-rata portion of the Additional Annual Chairperson Equity Award grant value for purposes of a Pro-Rata Additional Annual Chairperson Equity Award will equal the Additional Annual Chairperson Equity Award grant value set forth above multiplied by a fraction (not greater than one), the numerator of which is 12 minus the number of whole months that as of the particular grant date had elapsed since the Company’s last annual meeting of shareholders at which an Additional Annual Chairperson Equity Award was granted by the Company to the Chairperson of the Board and the denominator of which is 12. Each Pro-Rata Additional Annual Chairperson Equity Award will vest in full on the earlier of (w) the first anniversary of the grant date, (x) the next annual meeting of the Company’s shareholders following the date of grant, (y) the consummation of a Change in Control (as defined in the Plan) or (z) the non-employee director’s death or termination of service on the Board due to Disability (as defined under the Equity Plan), subject to the non-employee director’s continued service on the Board through such vesting date. General Unless otherwise determined by the Board, each award of restricted stock units will be made under and subject to the terms and conditions of the Equity Plan and an equity award agreement in substantially the form approved by the Board, subject to the terms specified above. Each non-employee director may elect to defer 100% of their restricted stock units granted under this policy

4 subject to the terms of a deferral program approved by the Board or the Compensation Committee, if any. The Board or the Compensation Committee may also approve other equity grants to non-employee directors under the Equity Plan in addition to or in lieu of grants described in this policy. The Board or the Compensation Committee may change and otherwise revise the terms of equity awards to be granted under this policy, including, without limitation, the number of shares subject thereto, for awards of the same or different type granted on or after the date the Board determines to make any such change or revision. Without limiting the foregoing, the Board may determine to grant equity awards in the form of stock options in lieu of restricted stock units having an equivalent grant date fair value determined in accordance with the reasonable assumptions and methodologies employed by the Company for calculating the fair value of options (i.e., Black- Scholes) and restricted stock units for financial reporting purposes. The per share exercise price for all options granted under this policy will be one hundred percent (100%) of the per share fair market value as determined under the Equity Plan on the date of grant. The equity awards shall be subject to the terms and conditions of the Equity Plan (including the annual limits on non-employee director grants set forth in the Equity Plan) and an equity award agreement in substantially the form approved by the Board, subject to the terms specified above. Expense Reimbursement All directors will be entitled to reimbursement from the Company for their reasonable and customary out-of- pocket travel (including airfare and ground transportation), lodging and meal expenses incident to their attendance at meetings of the Board or committees thereof or in connection with other Board related business.

1 EMCORE CORPORATION General Insider Trading Policy (Amended June 15, 2023) I. PURPOSE The federal securities laws are designed to ensure that investors are on equal footing with insiders and have access to the same information in making their investment decisions. Anyone who has knowledge of material nonpublic information may be considered an “insider” for purposes of the federal securities laws prohibiting insider trading. As a result, it is a violation of the policy of EMCORE Corporation (the “Company”) and the federal securities laws for any officer, director or employee of the Company, or their immediate family (collectively, “Insiders”), to (a) trade in securities of the Company while aware of “material nonpublic information” concerning the Company, (b) trade in securities of other public companies based upon material nonpublic information that an Insider obtained in connection with their association with the Company, or (c) communicate, “tip” or disclose material nonpublic information about the Company or any other public company to anyone else, so that they may trade in securities based on that information. The Company’s Board of Directors has adopted the EMCORE Corporation General Insider Trading Policy (the “Policy”) to satisfy the Company’s obligation to prevent insider trading and to help Company personnel avoid the severe consequences associated with violations of the insider trading laws. The Policy also is intended to prevent even the appearance of improper conduct on the part of anyone employed by or associated with the Company. We have all worked hard over the years to establish a reputation for integrity and ethical conduct, and we can not afford to have that reputation damaged. II. THE CONSEQUENCES The consequences of an insider trading violation can be severe: A. Traders and Tippers Under federal securities laws, Company personnel, as well as anyone who receives a tip from Company personnel, who trade while aware of material nonpublic information may be subject to the following penalties: • A civil penalty of up to three times the profit gained or loss avoided; • A criminal fine of up to $5,000,000 (no matter how small the profit); and • A jail term of up to twenty years. Moreover, any Company personnel that “tips” material nonpublic information to another person who then trades (a tippee) is subject to the same penalties as the tippee, even if the Company employee did not trade and did not profit from the tippee’s trading.

2 B. Control Persons The Company and its supervisory personnel, if they fail to take appropriate steps to prevent illegal insider trading, may also be subject to the following penalties: • A civil penalty of up to $1,000,000 or, if greater, three times the profit gained or loss avoided as a result of an Insider’s violation; and • A criminal penalty of up to $25,000,000 dollars. C. Company-Imposed Sanctions An Insider’s failure to comply with the Policy may subject the Insider to Company- imposed sanctions, including dismissal for cause, whether or not the Insider’s failure to comply results in a violation of law. Needless to say, a violation of law, or even a Securities and Exchange Commission (“SEC”) investigation that does not result in prosecution, can tarnish one’s reputation, irreparably damage a career, and cause considerable disruption to the Company’s business. III. STATEMENT OF POLICY A. Prohibited Activities 1. No Insider of the Company who is aware of material nonpublic information relating to the Company may, directly or through other persons or entities, (a) buy or sell securities of the Company (other than a transaction described below under “Transactions Under Company Plans”), or engage in any other action to take personal advantage of that information, (b) pass that information on to others outside the Company, including family and friends, or (c) give trading advice of any kind about the Company’s securities to anyone, whether or not such Insider is aware of material nonpublic information about the Company. 2. In addition, no Insider who, in the course of working for or in association with the Company, learns of material nonpublic information about another public company may trade in that company’s securities, or provide that information to another person so that person can trade, until the information becomes public or is no longer material. 3. No Insider may trade in any Company security during any special trading blackout period as designated by the Compliance Officer (“Blackout Period”). The Compliance Officer shall also determine which Insiders are subject to the Blackout Period. If an Insider is subject to a Blackout Period, the Insider will not disclose that fact to any person without prior permission of the Compliance Officer. 4. Transactions that may be necessary or justifiable for independent reasons (such as the need to raise money for an emergency expenditure) are not excepted from the Policy. The securities laws do not recognize such mitigating circumstances, and, in any event, even the appearance of an improper transaction must be avoided to preserve the Company’s reputation for adhering to the highest standards of conduct.

3 B. Additional Prohibited Transactions The Company considers it improper and inappropriate for any Insider of the Company to engage in short-term or speculative transactions in the Company’s securities and other transactions in the Company’s securities that create the potential for heightened legal risk or the appearance of improper or inappropriate conduct even if they occur at a time when the Insider is not aware of material nonpublic information. Therefore, Insiders may not engage in any of the following transactions: 1. Short-term Trading. An Insider’s short-term trading of the Company’s securities may be distracting to the Insider and may unduly focus the Insider on the Company’s short-term stock market performance instead of the Company’s long- term business objectives. For these reasons, any Insider who purchases Company securities in the open market may not sell any Company securities of the same class (other than a transaction described below under “Transactions Under Company Plans”) during the six months following an open market purchase. 2. Short Sales. Short sales of the Company’s securities evidence an expectation on the part of the seller that the securities will decline in value, and therefore signal to the market that the seller has no confidence in the Company or its short-term prospects. In addition, short sales may reduce the seller’s incentive to improve the Company’s performance. For these reasons, no Insider may engage in any short sales of the Company’s securities. In addition, Section 16(c) of the Securities Exchange Act of 1934 (the “Exchange Act”) prohibits executive officers and directors from engaging in short sales. 3. Publicly Traded Options. A transaction in options is, in effect, a bet on the short-term movement of the Company’s stock and therefore creates the appearance that the Insider is trading based on inside information. Transactions in options also may focus the Insider’s attention on the Company’s short-term performance at the expense of the Company’s long-term objectives. Accordingly, no Insider may engage in any transactions in puts, calls or other derivative securities relating to the Company’s stock, on an exchange or in any other organized market. (Option positions arising from certain types of hedging transactions are governed by the section below captioned “Hedging Transactions.”) 4. Hedging Transactions. Hedging or monetizing transactions, such as prepaid variable forwards, equity swaps, collars and exchange funds, that are designed to hedge or offset any decrease in the market value of the Company’s securities, allow an Insider to lock in much of the value of his or her stock holdings, often in exchange for all or part of the potential for upside appreciation in the stock. These transactions allow the Insider to continue to own the Company’s securities without the full risks and rewards of ownership. When that occurs, the Insider may no longer have the same objectives as the Company’s other shareholders. Accordingly, Insiders are prohibited from entering into such hedging or monetizing transactions.

4 5. Margin Accounts and Pledges. Securities held in a margin account or as collateral for a loan may be sold by the broker without the customer’s consent if the customer fails to meet a margin call. Similarly, securities pledged (or hypothecated) as collateral for a loan may be sold in foreclosure if the borrower defaults on the loan. Because a margin sale or foreclosure sale may occur at a time when the Insider is aware of material nonpublic information or otherwise is not permitted to trade in Company securities, Insiders may not margin Company securities held in a margin account or pledge Company securities as collateral for a loan. If you have any questions regarding whether a transaction is prohibited you should contact the Compliance Officer. C. Material Information Material information is any information that a reasonable investor would consider important in making a decision to buy, hold, or sell securities. Any information that could reasonably be expected to affect the Company’s stock price, whether it is positive or negative, should be considered material. While it is not possible to identify all information that would be deemed “material,” the following types of information ordinarily would be considered material: • Projections or estimated results of operations, future earnings or losses, or other earnings guidance of the Company; • Financial performance, especially quarterly and year-end earnings and significant changes in financial performance outlook or liquidity of the Company; • Company projections that significantly differ from external expectations; • A pending or proposed merger, acquisition or tender offer; • Significant changes in business strategies; • A pending or proposed acquisition or disposition of a significant asset; • Declaration of a dividend, a change in dividend policy, the declaration of a stock split, • An offering of additional securities or other financing transactions out of the ordinary course; • A change in senior management; • A change in auditors or notification that the Company may no longer rely on the auditor’s report; • Development of a significant new product or process; • New or potential significant contracts, orders, suppliers, customers, or finance sources, or the loss thereof; • Significant joint ventures or strategic partnerships; • Approvals or denials of requests for regulatory approval by government agencies of products, patents or product export licenses; • Impending bankruptcy or the existence of severe liquidity problems; • Significant changes or developments in supplies or inventory, including significant product defects, recalls or product returns;

5 • A significant cybersecurity incident or vulnerability, such as a data breach, or any other significant disruption in the Company’s operations or loss, potential loss, breach or unauthorized access of its property or assets, whether at its facilities or through its information technology infrastructure. • Actual, threatened or potential exposure to significant litigation, or the resolution of such litigation; and • Analyst upgrades or downgrades of a Company security. Twenty-Twenty Hindsight. Remember, anyone scrutinizing your transactions will be doing so after the fact, with the benefit of hindsight. It is not possible to define all categories of material information, and you should recognize that the public, media, regulators and courts may use hindsight in judging what is material. Therefore, it is important to err on the side of caution and assume information is material if there is any doubt. As a practical matter, before engaging in any transaction, you should carefully consider how enforcement authorities and others might view the transaction in hindsight. D. “Nonpublic” Information If you are aware of material nonpublic information, you may not trade until the information has been disclosed broadly to the marketplace (such as by press release or an SEC filing) and the investing public has had time to absorb the information fully. To avoid the appearance of impropriety, as a general rule, information should not be considered fully absorbed by the marketplace until two full trading days after the information is released. If, for example, the Company were to make an announcement on a Monday afternoon after market close, you should not trade in the Company’s securities until after market close Wednesday afternoon. If an announcement were made on a Friday morning before market open, the following Tuesday morning at market open would generally be the first eligible trading day. E. Transactions by Family Members or Controlled Entities This Policy also applies to your family members who reside with you, anyone else who lives in your household, any family members who do not live in your household but whose transactions in company securities are directed by you or are subject to your influence or control (such as parents or children who consult with you before they trade in Company securities), and any entities that you influence or control, including any corporations, partnerships or trusts. You are responsible for the transactions of these other persons and therefore should make them aware of the need to confer with you before they trade in the Company’s securities. F. Post-Termination Transactions The Policy continues to apply to your transactions in Company securities even after you have terminated employment. If you are in possession of material nonpublic information when your employment terminates, you may not trade in Company securities until that information has become public or is no longer material.

6 G. Transactions Under Company Plans 1. Stock Option Exercises. The Policy does not apply to the exercise of an employee stock option, or to the exercise of a tax withholding right pursuant to which you elect to have the Company withhold shares subject to an option to satisfy tax withholding requirements. The Policy does apply, however, to any sale of stock as part of a broker-assisted cashless exercise of an option, or any other market sale for the purpose of generating the cash needed to pay the exercise price of an option. In other words, you may exercise options at any time so long as you pay cash for the exercise and do not sell any of the underlying shares. 2. Vesting of Restricted Stock Units. The Policy does not apply to the reacquisition or withholding of Company stock by the Company to satisfy a tax withholding obligation upon the vesting of restricted stock or stock unit awards or the sale of shares of Company stock to satisfy a tax withholding obligation upon the vesting of restricted stock or stock unit awards. 3. Employee Stock Purchase Plan. The Policy does not apply to purchases of Company stock in the employee stock purchase plan resulting from your periodic contribution of money to the plan pursuant to the election you made at the time of your enrollment in the plan. The Policy does apply to your election to participate in the plan for any enrollment period, and to your sales of Company stock purchased pursuant to the plan. IV. CONSULT THE COMPLIANCE OFFICER FOR GUIDANCE Any Insider who has a question about this Policy or its application to any proposed transaction may obtain additional guidance from the Compliance Officer before trading in Company securities. Ultimately, however, the responsibility for adhering to this Policy and avoiding unlawful transactions rests with the individual Insider. V. REPORTING OF VIOLATIONS Any Insider who learns of a violation or potential violation of this Policy must report the violation or potential violation immediately to the Compliance Officer or on an anonymous basis through the Company’s hotline. Upon receipt of notice of a potential violation of this Policy, the Compliance Officer: (i) shall seek the assistance of outside counsel to determine whether a violation may have occurred; (ii) shall report the potential violation of this Policy to the Audit Committee if the Compliance Officer concludes a violation occurred or if the Compliance Officer is unable to conclude that no violation occurred; and (iii) upon determining that any such violation has occurred, in consultation with the Company’s Disclosure Committee and, where appropriate, the Chair of the Audit Committee, will determine whether the Company should release any material nonpublic information. If the Compliance Officer or Audit Committee determines that a violation of the Policy occurred, they may discipline the Insider, including immediate termination. The Audit Committee may also report the violation to federal or state law enforcement agencies.

7 VI. TRADING COMPLIANCE OFFICER The Company has designated its principal legal officer as its Trading Compliance Officer (the “Compliance Officer”). The duties of the Compliance Officer include the following: • Administering this Policy and monitoring and enforcing compliance with all Policy provisions and procedures; • With the assistance of Human Resources, overseeing the training of new and existing officers, directors and employees of the requirements of this Policy; • Responding to all inquiries relating to this Policy and its procedures; • Designating and announcing Blackout Periods during which Insiders, as determined by the Compliance Officer, may not trade in Company securities; • Assisting in the preparation and filing of all required SEC reports relating to insider trading in Company securities, including without limitation Forms 3, 4, 5 and 144 and, if applicable, Schedules 13D and 13G; and • Proposing recommendations for revisions to the Policy to the Board of Directors as necessary to reflect changes in insider trading laws, regulations or rules of any applicable Self-Regulatory Organization or any federal or state governmental body. The Compliance Officer may designate one or more senior officers or a member of the Company’s in-house legal staff to perform the Compliance Officer’s duties. VII. ROLE OF INDEPENDENT DIRECTORS The Company’s independent directors shall be responsible for direct oversight of the Trading Compliance Program and the Compliance Officer. Moreover, the Company’s independent directors shall have regular access to the Compliance Officer, including the opportunity to meet with the Compliance Officer outside the presence of any senior executives.

74351603 EMCORE CORPORATION EXECUTIVE INSIDER TRADING POLICY (Amended June 15, 2023) This Executive Insider Trading Policy (the “Executive Policy”) applies to all members of the Board of Directors, senior officers (i.e., Vice Presidents who report directly to the CEO), any other key employees designated as such by the Compliance Officer and their immediate families (collectively, the “Executives”). In addition to the requirements of the Executive Policy, all Executives must comply with EMCORE Corporation’s General Insider Trading Policy, which, among other things, prohibits Executives, and members of their immediate families, from trading in Company securities while aware of material nonpublic information, as well as any other form of “insider trading.” The Company believes that additional restrictions are necessary because Executives may have greater access to material nonpublic information than other employees. These additional restrictions are for the benefit of both the Executive, who faces significant penalties (including imprisonment) for insider trading, as well as for the Company and its supervisory personnel, who may be liable for failing to adequately protect against insider trading. I. TRADING WINDOWS AND BLACKOUT PERIODS A. Trading Window for Executives Provided none of the restrictions on trading in Company securities as set forth in Sections III.A and III.B of the Company’s General Insider Trading Policy apply, Executives may trade in Company securities only during the period (i) beginning at the close of trading on the second full trading day following the Company’s widespread public release of quarterly or year-end earnings for the immediately preceding fiscal quarter and (ii) ending at the close of business on the fifteenth day of the third month of the then-current fiscal quarter (or if such a day is not a trading day, the last trading day occurring immediately prior to such fifteenth day) (“Trading Window”). B. No Trading During Trading Windows If Other Trading Restrictions Apply Notwithstanding the provisions of Section I.A. above, the restrictions on trading in Company securities as set forth in Sections III.A and III.B of the Company’s General Insider Trading Policy, including restrictions on trading while an Executive is aware of material nonpublic information concerning the Company, shall continue to apply during a Trading Window. C. No Trading During Blackout Periods

74351603 Notwithstanding the provisions of Section I.A. above, no Executive may trade in Company securities if the Compliance Officer designates a special blackout period (“Blackout Period”) and the Compliance Officer determines that the Executive is subject to that Blackout Period. The Compliance Officer may declare such Blackout Periods from time to time as conditions warrant. No Executive, whether or not subject to a Blackout Period, may disclose to any person that a Blackout Period has been designated. II. PRE-CLEARANCE OF TRADES During Trading Windows, trading is generally permitted, but all trades of Executives (except as described below) must be pre-approved in writing by the Compliance Officer. A. Procedures for Approving Executive Trades 1. Executive Trades. No Executive may trade in Company securities until: a. the Executive seeking to trade has notified the Compliance Officer in writing prior to the proposed trade(s) and the amount and nature of the proposed trade(s), b. The Executive seeking to trade has certified in writing to the Compliance Officer no more than one trading day prior to the request for approval of the proposed trade(s) that he or she is not aware of material nonpublic information concerning the Company. c. The Executive’s request is approved in writing by the Compliance Officer. 2. Compliance Officer Trades. If the Compliance Officer desires to complete any trades involving Company securities, he or she must first obtain the approval of the Chief Executive Officer or the Chief Financial Officer of the Company. 3. No Obligation to Approve Trades. The existence of the foregoing approval procedures does not in any way obligate the Compliance Officer (or, in the case of any trade by the Compliance Officer, the Chief Executive Officer or the Chief Financial Officer of the Company) to approve any trades requested by the Executive or the Compliance Officer. 4. All trades approved under this section must be exercised within five trading days of the approval (the “Approval Period”). Even if an Executive’s proposed trade has been approved by the Compliance Officer, the Executive remains responsible for determining if he or she is aware of material nonpublic information at the time of the trade, and any action by the Company, the Compliance Officer or any other employee pursuant to this policy does not constitute legal advice or insulate the Executive from potential liability under insider trading laws. Additionally, even if a proposed trade has been approved by the Compliance Officer, such trade may not be executed during the Approval Period if (i) the Executive becomes aware of material nonpublic information concerning the Company, (ii) the Compliance Officer subsequently revokes the approval,

74351603 or (iii) a Blackout Period subsequently commences. Further, if an Executive’s proposed transaction is not completed within the Approval Period (or if the Compliance Officer revokes the approval or notifies the Executive of a Blackout Period), the transaction must be resubmitted for pre-approval to the Compliance Officer before it may be executed. As used in this policy, “trading” includes gifts, contributions to trusts or any other direct or indirect transfer of Company securities. Notwithstanding anything to the contrary herein, Executives are not required to obtain approval for transactions described under the section of the EMCORE Corporation General Insider Trading Policy titled “Transactions Under Company Plans” or trades in the Company’s securities made pursuant to an effective 10b5-1 Plan that has been pre- approved in writing by the Compliance Officer pursuant to this policy. III. RELEVANCE OF EMCORE CORPORATION GENERAL INSIDER TRADING POLICY The foregoing restrictions are in addition to all restrictions set forth in the EMCORE Corporation General Insider Trading Policy. Other than pursuant to an effective 10b5-1 Plan, Executives may under no circumstances trade while in possession of material nonpublic information as described therein, and Executives may not engage in any transaction of the types described under “Additional Prohibited Transactions” therein without the advance approval of the Compliance Officer. IV. DISGORGEMENT OF SHORT-SWING PROFITS Executives are also reminded of the limitations on trading in Company securities imposed by Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). In general, purchases and sales of Company equity securities made within a six-month period will be matched up, and the Executive must disgorge any profits made as a result of such trades, unless one of the trades was subject to an available exemption under Section 16. Matched trades subject to Section 16 include: (i) a sale within six months of a purchase of Company securities; or (ii) a purchase within six months of a sale of Company securities. The foregoing obligations are without regard to any wrongdoing by the Executive; accordingly, all trades may be subject to the short-swing profit rules, regardless of the intent of the Executive or the circumstances underlying the transactions. The federal securities laws prohibit the Company from waiving the requirements of Section 16 or reimbursing an Executive once they have paid disgorgement to the Company. Please consult the Compliance Officer with any questions regarding Section 16. You should be aware that, for purposes of Section 16, cashless exercises of options are deemed to be sales. V. RULE 10b5-1 PLANS

74351603 It is the policy of the Company to encourage all Executives to adopt a 10b5-1 plan, as set forth in this section. Rule 10b5-l of the Exchange Act was adopted by the SEC to protect persons from insider trading liability for transactions under a written trading plan previously established at a time when the insider did not possess material nonpublic information. Under a properly established 10b5-1 plan with respect to securities (a “10b5-1 Plan”), Executives may complete transactions in Company securities at any time, including during blackout periods and outside trading windows or even when the Executive possesses material nonpublic information. Thus, a 10b5-1 Plan offers an opportunity for Executives to establish a systematic program of transactions in Company securities over periods of time that might include periods in which such transactions would otherwise be prohibited under the federal securities laws. A variety of arrangements can be structured to meet the requirements of Rule 10b5-1. In particular, a 10b5-1 Plan can take the form of a blind trust, other trust, pre-scheduled stock option exercises and sales, pre-arranged trading instructions and other brokerage and third-party arrangements over which the Executive has no control once the plan takes effect. Executives who desire to implement a 10b5-1 Plan must first obtain approval of the plan by the Compliance Officer. In order to be eligible for approval, In order to be eligible for approval, the 10b5-1 Plan must meet the following requirements under Rule 10b5-1: • The 10b5-1 Plan must be in the form of a binding written plan or contract; • The 10b5-1 Plan must be adopted when, and contain representations confirming that, the Executive is not aware of material nonpublic information about the Company or any of its subsidiaries; • The 10b5-1 Plan must be “entered into in good faith,” contain representations confirming that it is being “entered into in good faith,” and be operated in good faith and not as part of a plan or scheme to evade the general prohibition against trading while in possession of material nonpublic information; • The 10b5-1 Plan must specify the amount of securities to be traded, the prices and the dates of transactions or a written algorithm or formula for determining the amounts, prices, and dates of transactions; • After a 10b5-1 Plan is adopted, any purchases or sales of securities covered by the 10b5-1 Plan must be in compliance with the 10b5-1 Plan and the person adopting the 10b5-1 Plan may not exercise any subsequent influence over how, when, or whether to make purchases or sales of those securities or enter into hedging positions to account for his or her planned purchases or sales of those securities under the 10b5-1 Plan; • The 10b5-1 Plan must provide that the first trade shall not occur until the later of: (i) 90 days after the adoption or modification of the 10b5-1 Plan (e.g., change

74351603 to the amount, price, or timing of the purchase or sale of the securities underlying the 10b5-1 Plan.); or (ii) two business days following the disclosure in periodic reports on Forms 10-Q or 10-K of the Company’s financial results for the fiscal quarter in which the 10b5-1 Plan was adopted or modified, in either case, subject to a maximum of 120 days after adoption or modification of the 10b5-1 Plan; • During any 12-month period, no Executive may adopt more than one “single- trade” 10b5-1 Plan, which is a plan that is designed to effect the open market purchase or sale of the total amount of the securities subject to the 10b5-1 Plan in a single transaction; and • No more than one 10b5-1 Plan shall be in effect at any time with respect to Company securities beneficially owned by the Executive; provided, however, that the Executive may adopt a second 10b5-1 Plan in compliance with this 10b5-1 Plan Policy, including all applicable cooling-off periods, with any transactions to take effect upon the completion or expiration of his or her current 10b5-1 Plan. The Compliance Officer will maintain a copy of all 10b5-1 Plans. The Executive must provide the Compliance Officer written notice of any termination or modification of the 10b5-1 Plan (in which case, the modification must be approved in writing by the Compliance Officer prior to effectiveness and may not take effect until at least 90 days after the modified plan is approved by the Compliance Officer and adopted by the Executive).

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business	Description of Business We are a leading provider of sensors and navigation systems for the aerospace and defense market. We leverage industry-leading Photonic Integrated Chip (“PIC”) and Quartz Micro Electro-Mechanical System (“QMEMS”) chip-level technology to deliver state-of-the-art component and system-level products across our end-market applications. Over the last six years, EMCORE has expanded its scope and portfolio of inertial sensor products through the acquisitions of Systron Donner Inertial, Inc. (“SDI”) in June 2019, the Space and Navigation (“S&N”) business of L3Harris Technologies, Inc. in April 2022, and the Fiber Optic Gyroscope (“FOG”) and Inertial Navigation Systems business (“EMCORE Chicago”) of KVH Industries, Inc. in August 2022. Our multi-year transition from a broadband company to an inertial navigation company has now been completed following the sales of (i) our cable TV, wireless, sensing and defense optoelectronics business lines in October 2023 and (ii) our chips product line and indium phosphide wafer fabrication operations in April 2024. We have fully vertically-integrated manufacturing capability at our facilities in Budd Lake, NJ, Concord, CA, and Tinley Park, IL. These facilities support our manufacturing strategy for FOG, Ring Laser Gyro (“RLG”), PIC, and QMEMS products for inertial navigation. Our manufacturing facilities maintain ISO 9001 quality management certification, and we are AS9100 aerospace quality certified at our facilities in Concord, CA and Budd Lake, NJ. Our best-in-class components and systems support a broad array of inertial navigation applications. Our operations include quartz wafer fabrication, device design and production, fiber optic module and subsystem design and manufacture, and PIC-based and QMEMS-based component design and manufacture. Many of our manufacturing operations are computer-monitored or controlled to enhance production output and statistical control. Our manufacturing processes involve extensive quality assurance systems and performance testing.

Summary of Significant Accounting Policies	Sep. 30, 2024
Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Principles of Consolidation The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and include the assets, liabilities, shareholders’ equity, and operating results of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The Company is not the primary beneficiary of, nor do we hold a significant variable interest in, any variable interest entity. Discontinued Operations In April 2023, we initiated a restructuring program that included the strategic shutdown of our Broadband business segment (including our cable TV, wireless, sensing and chips product lines) and the discontinuance of our defense optoelectronics product line. During the quarter ended September 30, 2023, the Broadband business segment and defense optoelectronics product line were considered as held for sale based upon (i) the existence of an executed non-binding letter of intent to sell our Broadband business segment (other than our chips product line) and our defense optoelectronics product line and (ii) in consideration of ongoing negotiations for the sale of the chips business. Given the prospective sale of the Broadband business segment and defense optoelectronics product line, we identified these asset groups as discontinued operations during the quarter ended September 30, 2023. We ceased operations of our chips business and indium phosphide wafer fabrication facility during the quarter ended September 30, 2023. In accordance with the authoritative guidance for discontinued operations (Accounting Standards Codification (“ASC”) 205-20), the Company determined that these business lines met held-for sale and discontinued operations accounting criteria during the quarter ended September 30, 2023. Accordingly, the Company classified the results of these business lines as discontinued operations in its consolidated statements of operations and comprehensive loss for all periods presented. Additionally, the related assets and liabilities associated with these business lines were classified as held for sale in the September 30, 2023 consolidated balance sheet. See Note 17— Discontinued Operations for additional information. In October 2023, the Company entered into an Asset Purchase Agreement with Photonics Foundries, Inc., a Delaware corporation (“PF”) and Ortel LLC, a Delaware limited liability company and wholly-owned subsidiary of PF (the “Buyer”), and consummated a transaction pursuant to which (i) the Company transferred to the Buyer, and Buyer assumed, substantially all of the assets and liabilities primarily related to the Company’s TV, wireless, sensing and defense optoelectronics business lines (the “Businesses”), including with respect to employees, contracts, intellectual property and inventory, and (ii) Buyer provided a limited license back to the Company of the patents being sold to the Buyer (the “PF Transaction”). Also in October 2023, the Company entered into a non-binding letter of intent with Asia-Pacific Environment Investment Limited (“APEI”) to sell substantially all of the assets and liabilities related to the Company’s chips business, including assets related to the Company’s indium phosphide wafer fabrication operations. On April 30, 2024, the Company entered into an Asset Purchase Agreement (the “HieFo Purchase Agreement”) with HieFo Corporation, a Delaware corporation and affiliate of APEI (“HieFo”), pursuant to which the Company transferred to HieFo substantially all of the assets primarily related to the Company’s discontinued chips business line, including with respect to equipment, contracts, intellectual property and inventory, including without limitation the Company’s indium phosphide wafer fabrication equipment, in consideration for a purchase price equal to $2.9 million in cash and assumption by HieFo of certain assumed liabilities (collectively, the “Chips Transaction”). Going Concern Basis The consolidated financial statements included herein have been prepared in accordance with GAAP assuming we will continue as a going concern. The going concern assumption contemplates the realization of assets and satisfaction of liabilities in the normal course of business. However, substantial doubt about our ability to continue as a going concern exists. We have recently experienced significant losses from operations and used a significant amount of cash, amounting to a net loss of $31.2 million and net cash outflows from operations of $5.5 million for the fiscal year ended September 30, 2024, and we expect to continue to incur losses and use cash in our operations. As a result of our recent cash outflows, we have taken actions to manage our liquidity and will need to continue to manage our liquidity. As of September 30, 2024, our cash and cash equivalents totaled $11 million. We are evaluating the sufficiency of our existing balances of cash and cash equivalents, cash flows from continuing operations, together with additional actions we could take to further reduce our expenses and/or potentially raising capital through additional debt or equity issuances, or from the potential monetization of certain assets. In addition, on November 7, 2024, we entered into the Merger Agreement with Parent, Parent Group Member, and Merger Sub – see “Aerosphere Power Merger Agreement” in “Note 18 – Subsequent Events” below for additional information related to the Merger Agreement. However, we may not be successful in executing on our plans to manage our liquidity, including recognizing the expected benefits from our previously announced restructuring program, or raising additional funds if we elect to do so, and as a result substantial doubt about our ability to continue as a going concern exists. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities, as of the date of the financial statements, and the reported amounts of revenue and expenses during the reported period. Such estimates include accounts receivable, inventories, long-lived assets, product warranty liabilities, legal contingencies, income taxes, asset retirement obligations, and pension obligation, as well as the evaluation associated with the going concern determination. We develop estimates based on historical experience and on various assumptions about the future that are believed to be reasonable based on the best information available to us. Our reported financial position or results of operations may be materially different under changed conditions or when using different estimates and assumptions, particularly with respect to significant accounting policies. In the event that estimates or assumptions prove to differ from actual results, adjustments are made in subsequent periods to reflect more current information. Concentration of Credit Risk Financial instruments that may subject us to concentrations of credit risk consist primarily of accounts receivable. When necessary, we perform credit evaluations on customers’ financial condition and occasionally we request deposits in advance of shipping product to customers. These financial evaluations require significant judgment and are based on a variety of factors including, but not limited to, current economic trends, historical payment patterns, bad debt write-off experience, and financial review of the particular customer. Cash and Cash Equivalents Cash and cash equivalents consists primarily of bank deposits and highly liquid short-term investments with a maturity of three months or less at the time of purchase. Accounts Receivable We regularly evaluate the collectability of accounts receivable and maintain allowances for doubtful accounts for estimated losses resulting from the inability of customers to meet their financial obligations to us. The allowance is based on the age of receivables and a specific identification of receivables considered at risk of collection. We classify charges associated with the allowance for doubtful accounts as selling, general, and administrative expense. Inventory Inventory is stated at the lower of cost or net realizable value (first-in, first-out). Inventory that is expected to be used within the next 12 months is classified as current inventory. We write-down inventory once it has been determined that conditions exist that may not allow the inventory to be sold for its intended purpose or the inventory is determined to be excess or obsolete based on assumptions about future demand and market conditions. The charge related to inventory write-downs is recorded as cost of revenue. We evaluate inventory levels at least quarterly against an estimate of future demand on a significant part-by-part basis, in addition to determining its overall inventory risk. We have incurred, and may in the future incur, charges to write-down of inventory. The allowance for excess and obsolete inventory for the fiscal years ended September 30, 2024 and 2023 was $11.5 million and $10.0 million, respectively. See Note 5 - Inventory for additional information. Property, Plant, and Equipment Property, plant, and equipment are recorded at cost. Plant and equipment are depreciated on a straight-line basis over the estimated useful lives of the assets. We depreciate equipment over three to seven years, furniture and fixtures over five years, computer hardware and software over three to five years. Leasehold improvements are amortized over the lesser of the asset life or the lease term. Expenditures for repairs and maintenance are charged to expense as incurred. The costs for major renewals and improvements are capitalized and depreciated over their estimated useful lives of the related asset. The cost and related accumulated depreciation of the assets are removed from the accounts upon disposition and any resulting gain or loss is reflected in the consolidated statement of operations and comprehensive loss. See Note 6 - Property, Plant, and Equipment, net for additional information. Goodwill and Intangible Assets Intangible assets of the Company that are considered to have an indefinite life include goodwill and a certain Company trademark. Goodwill represents the excess of the purchase price in a business combination over the fair value of the net tangible and intangible assets acquired. We follow the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 350, Intangibles-Goodwill and Other (“ASC 350”). ASC 350 requires the completion of a goodwill impairment test and test of other indefinite lived intangible assets at least annually based on either an optional qualitative assessment (Step 0) or a quantitative analysis (Step 1) comparing the estimated fair value of a reporting unit or indefinite lived intangible asset to its carrying value as of the test date which is July 1st for the Company. See Note 7 - Intangible Assets and Goodwill for discussion on the impairment of all goodwill in the fiscal year ended September 30, 2023. Valuation of Long-lived Assets Long-lived assets consist primarily of finite-life intangible assets, net and property, plant, and equipment, net. Since long-lived assets are subject to amortization and depreciation/amortization, we review these assets for impairment in accordance with the provisions of ASC 360, Property, Plant, and Equipment. Intangible assets that are not considered to have an indefinite useful life are itemized in Note 7 - Intangible Assets and Goodwill and are amortized over their useful lives. We review long-lived assets for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. Impairment testing of long-lived assets consists of determining whether the carrying amount of the long-lived asset or asset group is recoverable, in other words, whether the sum of the future undiscounted cash flows expected to result from the use and eventual disposition of the asset or asset group exceeds the carrying amount. The determination of the existence of impairment involves judgments that are subjective in nature and may require the use of estimates in forecasting future results and cash flows related to an asset or group of assets. In making this determination, we use certain assumptions, including estimates of future cash flows expected to be generated by these assets, which are based on additional assumptions such as asset utilization, the length of service that assets will be used in operations, and estimated salvage values. Leases The Company determines if an arrangement is a lease at its inception. Right-of-use (“ROU”) assets and operating lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The Company uses its estimated incremental borrowing rate in determining the present value of lease payments considering the term of the lease, which is derived from information available at the lease commencement date. The lease term includes renewal options when it is reasonably certain that the option will be exercised, and excludes termination options. To the extent that the Company’s agreements have variable lease payments, the Company includes variable lease payments that depend on an index or a rate and excludes those that depend on facts or circumstances occurring after the commencement date, other than the passage of time. Lease expense for these leases is recognized on a straight-line basis over the lease term. The Company has elected not to recognize ROU assets and lease liabilities that arise from short-term (12 months or less) leases for any class of underlying asset. Operating leases are included in operating lease ROU assets, current operating lease liabilities, and non-current operating lease liabilities in the Company’s consolidated balance sheets. See Note 12 - Commitments and Contingencies for additional information. Asset Retirement and Environmental Obligations Pursuant to ASC 410, Asset Retirement and Environmental Obligations (“ARO”), an ARO is recorded when there is a legal obligation associated with the retirement of a tangible long-lived asset and the fair value of the liability can reasonably be estimated. Upon initial recognition of an ARO, a company increases the carrying amount of the long-lived asset by the same amount as the liability. Over time, the liabilities are accreted for the change in their present value through charges to operations costs. The initial capitalized costs are depleted over the useful lives of the related assets through charges to depreciation, and/or amortization. If the fair value of the estimated ARO changes, an adjustment is recorded to both the ARO and the asset retirement cost. Revisions in estimated liabilities can result from revisions of estimated inflation rates, escalating retirement costs, and changes in the estimated timing of settling ARO liabilities. See Note 12 - Commitments and Contingencies for additional information. Pension Plan With the acquisition of S&N, we acquired the assets and assumed the liabilities associated with a pension plan, now named the EMCORE Space & Navigation Corporation Pension Plan (the “Pension Plan”), which is a defined benefit pension plan providing postretirement benefits to certain employees. As of July 1, 2022, the Pension Plan was amended to freeze benefit plan accruals for participants. The investments in the Pension Plan are measured at fair value using quoted market prices or the net asset value per share as a practical expedient. The projected benefit obligations associated with the Pension Plan are determined based on actuarial models utilizing mortality tables and discount rates applied to the expected benefit term. See Note 8 - Benefit Plans for additional information. Fair Value of Financial Instruments We determine the fair value of financial instruments in accordance with ASC 820, Fair Value Measurements and Disclosures. ASC Topic 820 (“ASC 820”), Fair Value Measurements, establishes a valuation hierarchy for disclosure of the inputs to valuation techniques used to measure fair value. This standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value: •Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities. •Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the assets or liabilities, either directly or indirectly, through market corroboration, for substantially the full term of the financial instrument. •Level 3 inputs are unobservable inputs based on assumptions used to measure assets or liabilities at fair value. Classification of an asset or liability within this hierarchy is determined based on the lowest level input that is significant to the fair value measurement. Valuation techniques used to measure fair value under ASC 820 must maximize the use of observable inputs and minimize the use of unobservable inputs. Cash and cash equivalents consist primarily of bank deposits or highly liquid short-term investments with a maturity of three months or less at the time of purchase. Restricted cash represents cash temporarily reserved by the Company. Cash, cash equivalents, and restricted cash are based on Level 1 measurements. The carrying amounts of cash and cash equivalents, restricted cash, accounts receivable, contract assets, prepaid expenses, other current assets, accounts payable, accrued expenses and other current liabilities, and contract liabilities approximate fair value because of the short maturity of these instruments. The Company values its outstanding Warrant (as defined in Note 10 - Credit Agre ement below), which is classified as a liability, using the Monte Carlo Simulation for option pricing, a Level 3 fair value measurement with the assistance of a third-party valuation specialist. The significant unobservable inputs used by the specialists include, in each case of September 30, 2024, the expected volatility of 72.55% (based on historical daily stock price returns over a look-back period equal to the simulation term), a risk-free rate of 3.75%, a stock price of $2.21, a strike price of $2.73, an expected term of 9.58 years, a dividend yield of 0.00%, and an annual growth rate of 3.00% in shares outstanding. Changes in these inputs could result in materially different fair value measurements. Furthermore, the specialist assumed that the forced exercise provision will be enacted in all possible circumstances, that there could be replacement warrants granted on four separate dates with four unique strike prices, and that the probability of the put right being exercised is de minimis. The Company has and will continue to subsequently remeasure the fair value of the Warrant each reporting period as long as the Warrant remains classified as a liability, with changes in the fair value reported in loss on extinguishment of debt and change in fair value of warrant liability on the consolidated statements of operations and comprehensive loss. See Note 10 - Credit Agreement for the value of the Warrant calculated upon Issuance Date of April 29, 2024 and as of September 30, 2024. Revenue Recognition To determine the proper revenue recognition, we perform the following five steps: (a) identify the contract(s) with a customer; (b) identify the performance obligations in the contract; (c) determine the transaction price; (d) allocate the transaction price to the performance obligations in the contract; and (e) recognize revenue when (or as) we satisfy a performance obligation. We only apply the five step model to contracts when it is probable that we will collect the consideration we are entitled to in exchange for the goods or services we transfer to the customer. The majority of revenues are from product sales to customers pursuant to purchase orders. Revenues from product sales are recognized when the customer obtains control of our product, which occurs at a point in time. The Company has elected to account for shipping and handling activities as a fulfillment cost as permitted by the standard. When we perform shipping and handling activities after the transfer of control to the customer (e.g., when control transfers prior to delivery), they are considered fulfillment activities, and accordingly, the costs are accrued when the related revenue is recognized. We expense incremental costs of obtaining a contract as and when incurred if the expected amortization period of the asset that we would have recognized is one year or less. We also enter into non-recurring engineering contracts. We recognize revenue for these arrangements over time or at a point in time depending on our evaluation of when the customer obtains control of the promised goods or services. For contracts that include multiple performance obligations, we allocate revenue to each performance obligation based on estimates of the relative standalone selling price that we would charge the customer for each promised product or service. In addition, we follow the percentage of completion method of revenue recognition for contracts typically for products specific to the customer and for which there is no alternative use for the product. We recognize revenue progressively as the customer takes control of the manufactured products built to customer specifications. Under these manufacturing contracts with customers, the customer controls all of the work-in-progress as products are being built. We use a number of wholesale distributors around the world and recognize revenue when the wholesale distributor obtains control of our product, which occurs at a point in time, typically upon shipment. Wholesale distributors are contractually obligated to pay us on standard commercial terms, consistent with our end-use customers. We do not sell to wholesale distributors on consignment and do not give wholesale distributors a right-of-return. Accounts Receivable, Net Accounts receivable, net, include amounts billed and currently due from customers. The amounts due are stated at their net estimated realizable value. Payments are generally due within 90 days or less of invoicing and do not include a significant financing component. We maintain an allowance for credit loss to provide for the estimated amount of receivables that will not be collected. The allowance is based upon an assessment of customer creditworthiness, historical payment experience, the age of outstanding receivables, and collateral to the extent applicable. Contract Assets A contract asset is recognized when the Company has recognized revenue, but has not issued an invoice for payment. Contract assets are classified as current assets and transferred to receivables when the entitlement to payment becomes unconditional. The Company’s contract assets are generally converted to account receivables within 90 days, at which time the Company is entitled to payment of the fixed price upon delivery of the finished product subject to customer payment terms. Contract Liabilities A contract liability is recognized when the Company has billed and received payment from a customer, but has not yet earned revenue. Contract liabilities are classified as current liabilities and transferred to revenue when revenue recognition standards have been met. Remaining Performance Obligations Remaining performance obligations represent the transaction price of firm orders for long-term contracts for which control has not transferred to the customer. As of September 30, 2024, the aggregate amount of the transaction price allocated to remaining performance obligations was $11.2 million. The Company expects to recognize revenue on the remaining performance obligations by the end of fiscal year 2025. Product Warranty Reserves We provide customers with warranty claims for certain products and warranty-related services are not considered a separate performance obligation. Pursuant to ASC 450, Contingencies, we make estimates of product warranty expense using historical experience rates and accrue estimated warranty expense as a cost of revenue. We estimate the costs of warranty obligations based on historical experience of known product failure rates and anticipated rates of warranty claims, use of materials to repair or replace defective products, and service delivery costs incurred in correcting the product issues. In addition, from time to time, specific warranty accruals may be made if unforeseen technical problems arise. Disaggregation of Revenue For additional information on the disaggregated revenues by geographical region and major product category, see Note 14 – Revenue Information. Income Taxes In accordance with the authoritative guidance on accounting for income taxes, we recognize income taxes using an asset and liability approach. This approach requires the recognition of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in the consolidated financial statements or tax returns. The measurement of current and deferred taxes is based on provisions of the enacted tax law. The effects of future changes in tax laws or rates are not anticipated. The authoritative guidance provides for recognition of deferred tax assets if the realization of such deferred tax assets is more likely than not to occur based on an evaluation of all available evidence, both positive and negative, and the relative weight of the evidence. We have determined that at this time it is more likely than not that deferred tax assets attributable to all other items will not be realized, primarily due to uncertainties related to the ability to utilize net operating loss carryforwards before they expire. Accordingly, we have established a valuation allowance for such deferred tax assets which we do not expect to realize. If there is a change in the ability to realize deferred tax assets for which a valuation allowance has been established, then the tax valuation allowance may decrease in the period in which we determine that realization is more likely than not. Likewise, if we determine that it is not more likely than not that deferred tax assets will be realized, then a valuation allowance may be established for such deferred tax assets and the tax provision may increase in the period in which we make the determination. See Note 11 - Income and Other Taxes for additional information. Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements There were no recently adopted accounting pronouncements. Recent Accounting Standards or Updates Not Yet Effective In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures, a final standard on improvements to income tax disclosures. The standard requires disaggregated information about a reporting entity's effective tax rate reconciliation as well as information on income taxes paid. The standard is intended to benefit investors by providing more detailed income tax disclosures that would be useful in making capital allocation decisions and applies to all entities subject to income taxes. The new standard is effective for annual periods beginning after December 15, 2024. This accounting standard is effective in the first quarter of the Company's fiscal year ended September 30, 2026. The Company does not expect the adoption of this new guidance to have a material impact on the consolidated financial statements. In November 2023, the FASB issued ASU 2023-07, Improvements to Reportable Segment Disclosures, which enhanced the segment reporting requirements by introducing additional disclosure obligations, including significant segment expenses. The new standard is effective for annual periods beginning after December 15, 2023. This accounting standard is effective in the first quarter of the Company's fiscal year ended September 30, 2025. The Company does not expect the adoption of this new guidance to have a material impact on the consolidated financial statements.

During the fiscal year ended September 30, 2023, for the reporting unit formerly known as Aerospace & Defense, an indication of goodwill impairment (after electing to quantitatively test goodwill) was a trigger to test long-lived assets. Recoverability of the long-lived assets was measured by comparing the carrying amount of the asset groups to the future net undiscounted cash flows expected to be generated by the asset groups. The comparison indicated that the assets were recoverable.

Long-lived assets consist of property, plant, and equipment. As of September 30, 2024 and 2023, approximately all of our long-lived assets were located in the United States.

Credit Agreement	Sep. 30, 2024
Debt Disclosure [Abstract]
Credit Agreement	Credit Agreement Wingspire/Hale Credit Agreement On August 9, 2022, EMCORE and S&N, our wholly-owned subsidiary, entered into that certain Credit Agreement with the lenders party thereto and Wingspire Capital LLC (“Wingspire”), as administrative agent for the lenders, as amended pursuant to that First Amendment to Credit Agreement dated as of October 25, 2022, among EMCORE and S&N, EMCORE Chicago, our wholly-owned subsidiary (together with the Company and S&N, the “Borrowers”), the lenders party thereto and Wingspire, to add EMCORE Chicago as a Borrower and include certain of its assets in the borrowing base (as amended, the “Credit Agreement”). The Credit Agreement provided for two credit facilities: (a) an asset-based revolving credit facility in an aggregate principal amount of up to $40.0 million, subject to a borrowing base consisting of eligible accounts receivable and eligible inventory (subject to certain reserves), and (b) a term loan facility in an aggregate principal amount of approximately $6.0 million. On April 29, 2024, Wingspire, HCP-FVU, LLC, HCP Fund V-FVU, LLC and Bessel Holdings LLC (each an affiliate of Hale Capital Management, L.P. and collectively, “Hale” or “New Lenders”), and HCP-FVU, LLC, as administrative agent for New Lenders (in such capacity, the “Successor Agent”) entered into an Assignment Agreement (the “Assignment Agreement”) pursuant to which Hale acquired all of Wingspire’s interest in the credit facilities extended by Wingspire to the Company pursuant to the Credit Agreement and all of the Loan Documents (as defined in the Credit Agreement) and any other documents, instruments, certificates, financing statements and agreements relating to the Credit Agreement. In connection with the Assignment Agreement, the Company entered into a Forbearance Agreement and Second Amendment to Credit Agreement with S&N and EMCORE Chicago, Hale, and the Successor Agent dated April 29, 2024 (the “Forbearance Agreement”). Under the terms of the Forbearance Agreement, Hale agreed: (i) not to accelerate the obligations or exercise other default remedies under the Credit Agreement and related documents; (ii) not to enforce any of the provisions or terms of the Credit Agreement and the related collateral documents relating to the occurrence of one or more cash dominion trigger events; and (iii) to direct the Successor Agent not to accelerate the obligations, exercise default remedies or take any such enforcement action or enforcement of provisions under the Credit Agreement and related documents during the period (the “Forbearance Period”) beginning on April 29, 2024 through the earliest of: (i) May 31, 2024; (ii) the date that any breach or default occurs or is determined to have occurred under the Credit Agreement or any other related document, including the Forbearance Agreement; and (iii) the date that the Company initiates any judicial, administrative or arbitration proceeding against Hale or the Successor Agent. The Forbearance Agreement also amended the Credit Agreement, to, among other things, set a fixed interest rate of 12% per annum (with an additional 6% upon the occurrence and during the continuance of an event of default, which shall not apply during the Forbearance Period to any of the events of default as to which the forbearance applies) on each loan. The Forbearance Agreement reduced the aggregate principal amount that we could draw under the revolving credit facility from $40.0 million to $4.6 million, subject to a borrowing base consisting of eligible accounts receivable, eligible inventory and eligible equipment (subject to certain reserves). The Forbearance Agreement also provided that the Company could elect to pay all or a portion of the interest that would accrue under the Credit Agreement as payment-in-kind, which would allow the Company to increase the principal balance of the Loans due and payable upon maturity, rather than making interest payment in cash. In addition, the Forbearance Agreement provided for certain financial covenants, loosened the circumstances under which the Borrowers would have to comply with a fixed charge coverage ratio, and eliminated all restrictions relating to cash dominion. On April 29, 2024 (the “Issuance Date”), in consideration of the Forbearance Agreement, the Company issued to the Successor Agent a warrant (the “Warrant”) to purchase an aggregate of 1,810,528 (post-reverse split) shares of the Company’s common stock at an exercise price of $2.73 per share. The Warrant is exercisable, at any time and from time to time, for 10 years following the Issuance Date. Under the terms of the Warrant, we have a right to force Successor Agent to exercise the Warrant under certain Forced Exercise Conditions (as defined in the Warrant) and issue a replacement warrant, and Successor Agent has a right to require us to purchase the unexercised portion of the Warrant under certain circumstances, including upon a Fundamental Transaction (as defined in the Warrant). If we are required to purchase the unexercised portion of the Warrant, we may elect to pay such repurchase price in the form of an unsecured promissory note. The Company accounted for the Warrant in accordance with ASC 815-40 Derivatives and Hedging - Contract in Entity's Own Equity and ASC 470-50 Debt - Modifications and Extinguishments. As there are provisions in the Warrant agreement that indicate that neither of the two criteria necessary for equity classification are met, the Company recorded the Warrant’s fair value using the Black-Scholes valuation method on date of issuance of approximately $5.1 million as a non-current liability in the consolidated balance sheet. As the Company was legally released as the primary obligor by Wingspire and there is no continuing debt to Wingspire, a corresponding value of $5.1 million was recorded as loss on extinguishment of debt in the consolidated statement of operations and comprehensive loss. The Company has and will continue to subsequently remeasure the fair value of the Warrant each reporting period as long as the Warrant remains classified as a liability with changes in the fair value reported in loss on extinguishment of debt and change in fair value of warrant liability on the consolidated statements of operations and comprehensive loss. We believe that the assumptions used in the calculations of fair value of the warrant liability represent the best estimates of fair value. As of September 30, 2024, using the Monte Carlo simulation valuation method, the fair value of the Warrant using Level 3 inputs was recorded as a $4.7 million non-current liability in the consolidated balance sheet and for the fiscal year ended September 30, 2024 the corresponding net expense of $2.6 million and $4.7 million is included in loss on extinguishment of debt and change in fair value of warrant liability in the consolidated statement of operations and comprehensive loss. See Note 13 - Equity for further discussion of the Warrant. On August 5, 2024, we voluntarily prepaid approximately $9.4 million to repay in full all amounts outstanding and payable under the Credit Agreement, resulting in termination of the Credit Agreement. In connection with the termination of the Credit Agreement, the total amount repaid by the Company of approximately $9.4 million consisted of approximately $8.5 million of principal, approximately $0.8 million of accrued interest, including interest that would have accrued through the one-year anniversary of the Forbearance Agreement, approximately $0.1 million of prepayment premium and approximately $0.1 million of customary expenses of the Successor Agent and the Lenders. As a result of the Repayment, all of the Obligations (as defined in the Credit Agreement) were satisfied in full and the Credit Agreement, the other Loan Documents (as defined in the Credit Agreement) and any other documents, instruments, certificates, financing statements, and agreements related to the Credit Agreement terminated (collectively, the “Financing Documents”). As a result of the termination of the Credit Agreement, the Successor Agent, the Lenders and their respective participants, if any, have no further commitment to provide loans or other financial accommodations under the Credit Agreement or any of the other Loan Documents. We received confirmation (in the form of a customary payoff letter) of such termination from the Successor Agent on behalf of the Lenders.

Hale Warrant

The Warrant provides for certain adjustments to the exercise price and the number of shares issuable upon exercise of the Warrant in certain circumstances, including a full-ratchet anti-dilution adjustment in connection with certain issuances of common stock and convertible securities by the Company below the then current exercise price of the Warrant. The Company also agreed to register for resale with the SEC the shares issuable upon exercise of the Warrant. The Warrant contains restrictions on the Successor Agent’s ability to exercise the Warrant, such that the Successor Agent shall not be entitled to exercise the Warrant if the total number of shares of common stock then beneficially owned by the Successor Agent, and its affiliates and any other persons whose beneficial ownership of common stock would be aggregated with the Successor Agent’s other ownership of the Company’s common stock, exceeds 4.999% of the total number of issued and outstanding shares of common stock of the Company (the “Threshold Percentage”). However, the Successor Agent has the right at any time and from time to time, to increase the Threshold Percentage to 9.999%. Additionally, the Successor Agent shall not have the right to exercise the Warrant if the total number of shares of common stock then beneficially owned by the Successor Agent , and its affiliates and any other persons whose beneficial ownership of common stock would be aggregated with the Successor Agent’s other ownership of the Company’s common stock, exceeds 19.99%, unless shareholder approval is obtained by the Company, as may be required by the applicable rules and regulations of the Nasdaq Stock Market LLC (“Nasdaq”) or any such other exchange on which the Company’s shares are then listed, or unless such shareholder approval requirement has been waived by Nasdaq. Notwithstanding anything to the contrary in the Warrant, the sum of the number of shares of common stock that may be issued under the Warrant is limited to 19.99% of the Company’s outstanding shares of common stock as of the issuance date of the Warrant (the “Exchange Cap”), unless shareholder approval is obtained by the Company to issue more than the Exchange Cap, as may be required by the applicable rules and regulations of Nasdaq or any such other exchange on which the Company’s shares are then listed, or unless such shareholder approval requirement has been waived by Nasdaq. The initial fair value of the warrant of $5.1 million was estimated using the Black-Scholes valuation method and was recorded as a long-term liability on the consolidated balance sheet. The change in fair value of the warrant liability using the Monte Carlo simulation valuation method for the fiscal year ended September 30, 2024 was $4.7 million and is included in the consolidated statements of

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events Aerosphere Power Merger Agreement On November 7, 2024, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Velocity One Holdings, LP, a Delaware limited partnership (“Parent”), Aerosphere Power Inc., a New Jersey corporation that, at the effective time of the Merger (as defined below) will be an indirect wholly-owned subsidiary of Parent (“Parent Group Member”), and Velocity Merger Sub, Inc., a New Jersey corporation that, at the effective time of the Merger will be an indirect wholly owned subsidiary of Parent (“Merger Sub”). The Merger Agreement provides that, subject to the terms and conditions set forth in the Merger Agreement, Merger Sub will merge with and into the Company (the “Merger”), with the Company surviving the Merger and becoming an indirect wholly owned subsidiary of Parent. Our Board of Directors unanimously (i) determined that the transactions contemplated by the Merger Agreement, including the Merger, are advisable, fair to, and in the best interests of the Company and our shareholders; (ii) approved the Merger Agreement and the transactions contemplated by the Merger Agreement; and (iii) recommended that our shareholders vote to adopt and approve the Merger Agreement and the Merger. Under the Merger Agreement, at the effective time of the Merger, each issued and outstanding share of common stock, no par value, of the Company (subject to certain exceptions set forth in the Merger Agreement) will be converted into the right to receive $3.10 per share (the “Merger Consideration”) in cash, without interest, subject to any withholding taxes. Immediately prior to the effective time of the Merger: •each outstanding restricted stock unit award subject to time-based vesting restrictions, whether vested or unvested, that is outstanding under any of the Company’s 2010 Plan, 2012 Equity Incentive Plan, 2019 Plan, 2022 New Employee Inducement Plan, Officer and Director Share Purchase Plan, Directors’ Compensation Policy, and Short-Term Incentive Plan, in each case, as amended (each a “Company Equity Plan”) will be canceled in consideration for the right to receive a lump sum cash payment (less any applicable tax withholdings) equal to the product obtained by multiplying (1) the amount of the Merger Consideration by (2) the total number of shares of the Company’s common stock represented by such restricted stock unit award subject to time-based vesting restrictions; •each outstanding restricted stock unit award subject to performance vesting conditions that is outstanding under any Company Equity Plan (a) to the extent not vested, will be deemed to have satisfied such performance vesting conditions at 100% of target and will have any time-based vesting conditions waived, and (b) will be canceled in consideration for the right to receive a lump sum cash payment (less any applicable tax withholdings) equal to the product obtained by multiplying (1) the amount of the Merger Consideration by (2) the total number of shares of the Company’s common stock represented by such restricted stock unit award subject to performance vesting conditions; and •each outstanding stock option of the Company (if any), whether vested or unvested, will be canceled and converted into the right to receive (without interest) a lump sum cash payment (less applicable tax withholdings) equal to the product obtained by multiplying (1) the excess, if any, of the amount of the Merger Consideration over the per share exercise price of such stock option by (2) the total number of shares of the Company’s common stock underlying such stock option. Any stock option, whether vested or unvested, for which the per share exercise price attributable to such stock option is equal to or greater than the Merger Consideration will be canceled as of the effective time of the Merger for no consideration. There are currently no awards outstanding under the 2010 Plan and the 2012 Equity Incentive Plan, nor are there expected to be any awards outstanding under these plans prior to or at the closing of the Merger. Consummation of the Merger is subject to the satisfaction or waiver of customary closing conditions, including: (1) the accuracy of the representations and warranties contained in the Merger Agreement, subject to certain customary materiality qualifications, as of the date of the Merger Agreement and as of the closing of the Proposed Transaction, and performance in all material respects of all obligations, and compliance in all material respects with the agreements and covenants, contained in the Merger Agreement, (2) approval by our shareholders of the Merger Agreement and the transactions contemplated by the Merger Agreement, (3) the absence of any laws or orders by a governmental entity having jurisdiction over any party to the Merger Agreement that make illegal, enjoin, or prohibit consummation of the Merger or the transactions contemplated by the Merger Agreement, and (4) the absence of a Company Material Adverse Effect (as defined in the Merger Agreement) between the date of the Merger Agreement and the closing of the Merger. Assuming the satisfaction of the conditions set forth in the Merger Agreement, we expect the Merger to close during the quarter ending March 31, 2025. Following the effective time of the Merger, our common stock will be delisted from Nasdaq and deregistered under the Securities Exchange Act of 1934, as amended.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
Summary of Significant Accounting Policies (Policies)	Sep. 30, 2024
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and include the assets, liabilities, shareholders’ equity, and operating results of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The Company is not the primary beneficiary of, nor do we hold a significant variable interest in, any variable interest entity.
Discontinued Operations	Discontinued Operations In April 2023, we initiated a restructuring program that included the strategic shutdown of our Broadband business segment (including our cable TV, wireless, sensing and chips product lines) and the discontinuance of our defense optoelectronics product line. During the quarter ended September 30, 2023, the Broadband business segment and defense optoelectronics product line were considered as held for sale based upon (i) the existence of an executed non-binding letter of intent to sell our Broadband business segment (other than our chips product line) and our defense optoelectronics product line and (ii) in consideration of ongoing negotiations for the sale of the chips business. Given the prospective sale of the Broadband business segment and defense optoelectronics product line, we identified these asset groups as discontinued operations during the quarter ended September 30, 2023. We ceased operations of our chips business and indium phosphide wafer fabrication facility during the quarter ended September 30, 2023. In accordance with the authoritative guidance for discontinued operations (Accounting Standards Codification (“ASC”) 205-20), the Company determined that these business lines met held-for sale and discontinued operations accounting criteria during the quarter ended September 30, 2023. Accordingly, the Company classified the results of these business lines as discontinued operations in its consolidated statements of operations and comprehensive loss for all periods presented. Additionally, the related assets and liabilities associated with these business lines were classified as held for sale in the September 30, 2023 consolidated balance sheet. See Note 17— Discontinued Operations for additional information. In October 2023, the Company entered into an Asset Purchase Agreement with Photonics Foundries, Inc., a Delaware corporation (“PF”) and Ortel LLC, a Delaware limited liability company and wholly-owned subsidiary of PF (the “Buyer”), and consummated a transaction pursuant to which (i) the Company transferred to the Buyer, and Buyer assumed, substantially all of the assets and liabilities primarily related to the Company’s TV, wireless, sensing and defense optoelectronics business lines (the “Businesses”), including with respect to employees, contracts, intellectual property and inventory, and (ii) Buyer provided a limited license back to the Company of the patents being sold to the Buyer (the “PF Transaction”). Also in October 2023, the Company entered into a non-binding letter of intent with Asia-Pacific Environment Investment Limited (“APEI”) to sell substantially all of the assets and liabilities related to the Company’s chips business, including assets related to the Company’s indium phosphide wafer fabrication operations. On April 30, 2024, the Company entered into an Asset Purchase Agreement (the “HieFo Purchase Agreement”) with HieFo Corporation, a Delaware corporation and affiliate of APEI (“HieFo”), pursuant to which the Company transferred to HieFo substantially all of the assets primarily related to the Company’s discontinued chips business line, including with respect to equipment, contracts, intellectual property and inventory, including without limitation the Company’s indium phosphide wafer fabrication equipment, in consideration for a purchase price equal to $2.9 million in cash and assumption by HieFo of certain assumed liabilities (collectively, the “Chips Transaction”).
Going Concern Basis	Going Concern Basis The consolidated financial statements included herein have been prepared in accordance with GAAP assuming we will continue as a going concern. The going concern assumption contemplates the realization of assets and satisfaction of liabilities in the normal course of business. However, substantial doubt about our ability to continue as a going concern exists. We have recently experienced significant losses from operations and used a significant amount of cash, amounting to a net loss of $31.2 million and net cash outflows from operations of $5.5 million for the fiscal year ended September 30, 2024, and we expect to continue to incur losses and use cash in our operations. As a result of our recent cash outflows, we have taken actions to manage our liquidity and will need to continue to manage our liquidity. As of September 30, 2024, our cash and cash equivalents totaled $11 million. We are evaluating the sufficiency of our existing balances of cash and cash equivalents, cash flows from continuing operations, together with additional actions we could take to further reduce our expenses and/or potentially raising capital through additional debt or equity issuances, or from the potential monetization of certain assets. In addition, on November 7, 2024, we entered into the Merger Agreement with Parent, Parent Group Member, and Merger Sub – see “Aerosphere Power Merger Agreement” in “Note 18 – Subsequent Events” below for additional information related to the Merger Agreement. However, we may not be successful in executing on our plans to manage our liquidity, including recognizing the expected benefits from our previously announced restructuring program, or raising additional funds if we elect to do so, and as a result substantial doubt about our ability to continue as a going concern exists.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities, as of the date of the financial statements, and the reported amounts of revenue and expenses during the reported period. Such estimates include accounts receivable, inventories, long-lived assets, product warranty liabilities, legal contingencies, income taxes, asset retirement obligations, and pension obligation, as well as the evaluation associated with the going concern determination. We develop estimates based on historical experience and on various assumptions about the future that are believed to be reasonable based on the best information available to us. Our reported financial position or results of operations may be materially different under changed conditions or when using different estimates and assumptions, particularly with respect to significant accounting policies. In the event that estimates or assumptions prove to differ from actual results, adjustments are made in subsequent periods to reflect more current information.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that may subject us to concentrations of credit risk consist primarily of accounts receivable. When necessary, we perform credit evaluations on customers’ financial condition and occasionally we request deposits in advance of shipping product to customers. These financial evaluations require significant judgment and are based on a variety of factors including, but not limited to, current economic trends, historical payment patterns, bad debt write-off experience, and financial review of the particular customer.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consists primarily of bank deposits and highly liquid short-term investments with a maturity of three months or less at the time of purchase.
Accounts Receivable	Accounts Receivable We regularly evaluate the collectability of accounts receivable and maintain allowances for doubtful accounts for estimated losses resulting from the inability of customers to meet their financial obligations to us. The allowance is based on the age of receivables and a specific identification of receivables considered at risk of collection. We classify charges associated with the allowance for doubtful accounts as selling, general, and administrative expense.
Inventory	Inventory Inventory is stated at the lower of cost or net realizable value (first-in, first-out). Inventory that is expected to be used within the next 12 months is classified as current inventory. We write-down inventory once it has been determined that conditions exist that may not allow the inventory to be sold for its intended purpose or the inventory is determined to be excess or obsolete based on assumptions about future demand and market conditions. The charge related to inventory write-downs is recorded as cost of revenue. We evaluate inventory levels at least quarterly against an estimate of future demand on a significant part-by-part basis, in addition to determining its overall inventory risk. We have incurred, and may in the future incur, charges to write-down of inventory. The allowance for excess and obsolete inventory for the fiscal years ended September 30, 2024 and 2023 was $11.5 million and $10.0 million, respectively. See Note 5 - Inventory for additional information.
Property, Plant, and Equipment	Property, Plant, and Equipment Property, plant, and equipment are recorded at cost. Plant and equipment are depreciated on a straight-line basis over the estimated useful lives of the assets. We depreciate equipment over three to seven years, furniture and fixtures over five years, computer hardware and software over three to five years. Leasehold improvements are amortized over the lesser of the asset life or the lease term. Expenditures for repairs and maintenance are charged to expense as incurred. The costs for major renewals and improvements are capitalized and depreciated over their estimated useful lives of the related asset. The cost and related accumulated depreciation of the assets are removed from the accounts upon disposition and any resulting gain or loss is reflected in the consolidated statement of operations and comprehensive loss. See Note 6 - Property, Plant, and Equipment, net for additional information.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Intangible assets of the Company that are considered to have an indefinite life include goodwill and a certain Company trademark. Goodwill represents the excess of the purchase price in a business combination over the fair value of the net tangible and intangible assets acquired. We follow the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 350, Intangibles-Goodwill and Other (“ASC 350”). ASC 350 requires the completion of a goodwill impairment test and test of other indefinite lived intangible assets at least annually based on either an optional qualitative assessment (Step 0) or a quantitative analysis (Step 1) comparing the estimated fair value of a reporting unit or indefinite lived intangible asset to its carrying value as of the test date which is July 1st for the Company. See Note 7 - Intangible Assets and Goodwill for discussion on the impairment of all goodwill in the fiscal year ended September 30, 2023.
Valuation of Long-lived Assets	Valuation of Long-lived Assets Long-lived assets consist primarily of finite-life intangible assets, net and property, plant, and equipment, net. Since long-lived assets are subject to amortization and depreciation/amortization, we review these assets for impairment in accordance with the provisions of ASC 360, Property, Plant, and Equipment. Intangible assets that are not considered to have an indefinite useful life are itemized in Note 7 - Intangible Assets and Goodwill and are amortized over their useful lives. We review long-lived assets for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. Impairment testing of long-lived assets consists of determining whether the carrying amount of the long-lived asset or asset group is recoverable, in other words, whether the sum of the future undiscounted cash flows expected to result from the use and eventual disposition of the asset or asset group exceeds the carrying amount. The determination of the existence of impairment involves judgments that are subjective in nature and may require the use of estimates in forecasting future results and cash flows related to an asset or group of assets. In making this determination, we use certain assumptions, including estimates of future cash flows expected to be generated by these assets, which are based on additional assumptions such as asset utilization, the length of service that assets will be used in operations, and estimated salvage values.
Leases	Leases The Company determines if an arrangement is a lease at its inception. Right-of-use (“ROU”) assets and operating lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The Company uses its estimated incremental borrowing rate in determining the present value of lease payments considering the term of the lease, which is derived from information available at the lease commencement date. The lease term includes renewal options when it is reasonably certain that the option will be exercised, and excludes termination options. To the extent that the Company’s agreements have variable lease payments, the Company includes variable lease payments that depend on an index or a rate and excludes those that depend on facts or circumstances occurring after the commencement date, other than the passage of time. Lease expense for these leases is recognized on a straight-line basis over the lease term. The Company has elected not to recognize ROU assets and lease liabilities that arise from short-term (12 months or less) leases for any class of underlying asset. Operating leases are included in operating lease ROU assets, current operating lease liabilities, and non-current operating lease liabilities in the Company’s consolidated balance sheets. See Note 12 - Commitments and Contingencies for additional information.
Asset Retirement and Environmental Obligations	Asset Retirement and Environmental Obligations Pursuant to ASC 410, Asset Retirement and Environmental Obligations (“ARO”), an ARO is recorded when there is a legal obligation associated with the retirement of a tangible long-lived asset and the fair value of the liability can reasonably be estimated. Upon initial recognition of an ARO, a company increases the carrying amount of the long-lived asset by the same amount as the liability. Over time, the liabilities are accreted for the change in their present value through charges to operations costs. The initial capitalized costs are depleted over the useful lives of the related assets through charges to depreciation, and/or amortization. If the fair value of the estimated ARO changes, an adjustment is recorded to both the ARO and the asset retirement cost. Revisions in estimated liabilities can result from revisions of estimated inflation rates, escalating retirement costs, and changes in the estimated timing of settling ARO liabilities. See Note 12 - Commitments and Contingencies for additional information. Asset Retirement Obligations ARO consists of legal requirements to decommission assets, restore the existing leased facilities to their original state, and perform certain environmental work due to the presence of a manufacturing fabrication operation. ARO includes assumptions related to renewal option periods for those facilities where we expect to extend lease terms. The Company recognizes its estimate of the fair value of its ARO in the period incurred in long-term liabilities and is also capitalized as property, plant and equipment.
Pension Plan	Pension Plan With the acquisition of S&N, we acquired the assets and assumed the liabilities associated with a pension plan, now named the EMCORE Space & Navigation Corporation Pension Plan (the “Pension Plan”), which is a defined benefit pension plan providing postretirement benefits to certain employees. As of July 1, 2022, the Pension Plan was amended to freeze benefit plan accruals for participants. The investments in the Pension Plan are measured at fair value using quoted market prices or the net asset value per share as a practical expedient. The projected benefit obligations associated with the Pension Plan are determined based on actuarial models utilizing mortality tables and discount rates applied to the expected benefit term. See Note 8 - Benefit Plans for additional information.
Fair Value of Financial Instruments	Fair Value of Financial Instruments We determine the fair value of financial instruments in accordance with ASC 820, Fair Value Measurements and Disclosures. ASC Topic 820 (“ASC 820”), Fair Value Measurements, establishes a valuation hierarchy for disclosure of the inputs to valuation techniques used to measure fair value. This standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value: •Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities. •Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the assets or liabilities, either directly or indirectly, through market corroboration, for substantially the full term of the financial instrument. •Level 3 inputs are unobservable inputs based on assumptions used to measure assets or liabilities at fair value. Classification of an asset or liability within this hierarchy is determined based on the lowest level input that is significant to the fair value measurement. Valuation techniques used to measure fair value under ASC 820 must maximize the use of observable inputs and minimize the use of unobservable inputs. Cash and cash equivalents consist primarily of bank deposits or highly liquid short-term investments with a maturity of three months or less at the time of purchase. Restricted cash represents cash temporarily reserved by the Company. Cash, cash equivalents, and restricted cash are based on Level 1 measurements. The carrying amounts of cash and cash equivalents, restricted cash, accounts receivable, contract assets, prepaid expenses, other current assets, accounts payable, accrued expenses and other current liabilities, and contract liabilities approximate fair value because of the short maturity of these instruments. The Company values its outstanding Warrant (as defined in Note 10 - Credit Agre ement below), which is classified as a liability, using the Monte Carlo Simulation for option pricing, a Level 3 fair value measurement with the assistance of a third-party valuation specialist. The significant unobservable inputs used by the specialists include, in each case of September 30, 2024, the expected volatility of 72.55% (based on historical daily stock price returns over a look-back period equal to the simulation term), a risk-free rate of 3.75%, a stock price of $2.21, a strike price of $2.73, an expected term of 9.58 years, a dividend yield of 0.00%, and an annual growth rate of 3.00% in shares outstanding. Changes in these inputs could result in materially different fair value measurements. Furthermore, the specialist assumed that the forced exercise provision will be enacted in all possible circumstances, that there could be replacement warrants granted on four separate dates with four unique strike prices, and that the probability of the put right being exercised is de minimis. The Company has and will continue to subsequently remeasure the fair value of the Warrant each reporting period as long as the Warrant remains classified as a liability, with changes in the fair value reported in loss on extinguishment of debt and change in fair value of warrant liability on the consolidated statements of operations and comprehensive loss. See Note 10 - Credit Agreement for the value of the Warrant calculated upon Issuance Date of April 29, 2024 and as of September 30, 2024.
Revenue Recognition, Remaining Performance Obligations, and Disaggregation of Revenue	Revenue Recognition To determine the proper revenue recognition, we perform the following five steps: (a) identify the contract(s) with a customer; (b) identify the performance obligations in the contract; (c) determine the transaction price; (d) allocate the transaction price to the performance obligations in the contract; and (e) recognize revenue when (or as) we satisfy a performance obligation. We only apply the five step model to contracts when it is probable that we will collect the consideration we are entitled to in exchange for the goods or services we transfer to the customer. The majority of revenues are from product sales to customers pursuant to purchase orders. Revenues from product sales are recognized when the customer obtains control of our product, which occurs at a point in time. The Company has elected to account for shipping and handling activities as a fulfillment cost as permitted by the standard. When we perform shipping and handling activities after the transfer of control to the customer (e.g., when control transfers prior to delivery), they are considered fulfillment activities, and accordingly, the costs are accrued when the related revenue is recognized. We expense incremental costs of obtaining a contract as and when incurred if the expected amortization period of the asset that we would have recognized is one year or less. We also enter into non-recurring engineering contracts. We recognize revenue for these arrangements over time or at a point in time depending on our evaluation of when the customer obtains control of the promised goods or services. For contracts that include multiple performance obligations, we allocate revenue to each performance obligation based on estimates of the relative standalone selling price that we would charge the customer for each promised product or service. In addition, we follow the percentage of completion method of revenue recognition for contracts typically for products specific to the customer and for which there is no alternative use for the product. We recognize revenue progressively as the customer takes control of the manufactured products built to customer specifications. Under these manufacturing contracts with customers, the customer controls all of the work-in-progress as products are being built. We use a number of wholesale distributors around the world and recognize revenue when the wholesale distributor obtains control of our product, which occurs at a point in time, typically upon shipment. Wholesale distributors are contractually obligated to pay us on standard commercial terms, consistent with our end-use customers. We do not sell to wholesale distributors on consignment and do not give wholesale distributors a right-of-return. Remaining Performance Obligations Remaining performance obligations represent the transaction price of firm orders for long-term contracts for which control has not transferred to the customer. As of September 30, 2024, the aggregate amount of the transaction price allocated to remaining performance obligations was $11.2 million. The Company expects to recognize revenue on the remaining performance obligations by the end of fiscal year 2025. Disaggregation of Revenue For additional information on the disaggregated revenues by geographical region and major product category, see Note 14 – Revenue Information.
Accounts Receivable, Net	Accounts Receivable, Net Accounts receivable, net, include amounts billed and currently due from customers. The amounts due are stated at their net estimated realizable value. Payments are generally due within 90 days or less of invoicing and do not include a significant financing component. We maintain an allowance for credit loss to provide for the estimated amount of receivables that will not be collected. The allowance is based upon an assessment of customer creditworthiness, historical payment experience, the age of outstanding receivables, and collateral to the extent applicable. Contract Assets A contract asset is recognized when the Company has recognized revenue, but has not issued an invoice for payment. Contract assets are classified as current assets and transferred to receivables when the entitlement to payment becomes unconditional. The Company’s contract assets are generally converted to account receivables within 90 days, at which time the Company is entitled to payment of the fixed price upon delivery of the finished product subject to customer payment terms. Contract Liabilities A contract liability is recognized when the Company has billed and received payment from a customer, but has not yet earned revenue. Contract liabilities are classified as current liabilities and transferred to revenue when revenue recognition standards have been met.
Product Warranty Reserves	Product Warranty Reserves We provide customers with warranty claims for certain products and warranty-related services are not considered a separate performance obligation. Pursuant to ASC 450, Contingencies, we make estimates of product warranty expense using historical experience rates and accrue estimated warranty expense as a cost of revenue. We estimate the costs of warranty obligations based on historical experience of known product failure rates and anticipated rates of warranty claims, use of materials to repair or replace defective products, and service delivery costs incurred in correcting the product issues. In addition, from time to time, specific warranty accruals may be made if unforeseen technical problems arise.
Income Taxes	Income Taxes In accordance with the authoritative guidance on accounting for income taxes, we recognize income taxes using an asset and liability approach. This approach requires the recognition of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in the consolidated financial statements or tax returns. The measurement of current and deferred taxes is based on provisions of the enacted tax law. The effects of future changes in tax laws or rates are not anticipated. The authoritative guidance provides for recognition of deferred tax assets if the realization of such deferred tax assets is more likely than not to occur based on an evaluation of all available evidence, both positive and negative, and the relative weight of the evidence. We have determined that at this time it is more likely than not that deferred tax assets attributable to all other items will not be realized, primarily due to uncertainties related to the ability to utilize net operating loss carryforwards before they expire. Accordingly, we have established a valuation allowance for such deferred tax assets which we do not expect to realize. If there is a change in the ability to realize deferred tax assets for which a valuation allowance has been established, then the tax valuation allowance may decrease in the period in which we determine that realization is more likely than not. Likewise, if we determine that it is not more likely than not that deferred tax assets will be realized, then a valuation allowance may be established for such deferred tax assets and the tax provision may increase in the period in which we make the determination. See Note 11 - Income and Other Taxes for additional information.
Recently Adopted Accounting Pronouncements and Recent Accounting Standards or Updates Not Yet Effective	Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements There were no recently adopted accounting pronouncements. Recent Accounting Standards or Updates Not Yet Effective In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures, a final standard on improvements to income tax disclosures. The standard requires disaggregated information about a reporting entity's effective tax rate reconciliation as well as information on income taxes paid. The standard is intended to benefit investors by providing more detailed income tax disclosures that would be useful in making capital allocation decisions and applies to all entities subject to income taxes. The new standard is effective for annual periods beginning after December 15, 2024. This accounting standard is effective in the first quarter of the Company's fiscal year ended September 30, 2026. The Company does not expect the adoption of this new guidance to have a material impact on the consolidated financial statements. In November 2023, the FASB issued ASU 2023-07, Improvements to Reportable Segment Disclosures, which enhanced the segment reporting requirements by introducing additional disclosure obligations, including significant segment expenses. The new standard is effective for annual periods beginning after December 15, 2023. This accounting standard is effective in the first quarter of the Company's fiscal year ended September 30, 2025. The Company does not expect the adoption of this new guidance to have a material impact on the consolidated financial statements.
Legal Costs	Professional legal fees are expensed when incurred. We accrue for contingent losses when such losses are probable and reasonably estimable.
