1. Description of Business

Stereotaxis designs, manufactures and markets robotic systems, instruments and information systems for the interventional laboratory. Our proprietary robotic technology, Robotic Magnetic Navigation, fundamentally transforms endovascular interventions using precise computer-controlled magnetic fields to directly control the tip of flexible interventional catheters or devices. Direct control of the tip of an interventional device, in contrast to all manual hand-held devices that are controlled from their handle, can improve the precision, stability, reach and safety of these devices during procedures.

Our primary clinical focus has been electrophysiology, specifically cardiac ablation procedures for the treatment of arrhythmias. Cardiac ablation has become a well-accepted therapy for arrhythmias and a multi-billion-dollar medical device market with expectations for substantial long-term growth. Our product strategy is to expand the clinical focus of our technology to several additional endovascular indications including coronary, neuro, and peripheral interventions.

There is substantial real-world evidence and clinical literature for Robotic Magnetic Navigation in electrophysiology. Hundreds of electrophysiologists at over one hundred hospitals globally have treated over 100,000 arrhythmia patients with our robotic technology. Clinical use of our technology has been documented in over 400 clinical publications. Robotic Magnetic Navigation is designed to enable physicians to complete more complex interventional procedures with greater success and safety by providing image-guided delivery of catheters through the blood vessels and chambers of the heart to treatment sites. This is achieved using externally applied computer-controlled magnetic fields that govern the motion of the working tip of the catheter, resulting in improved navigation. The more flexible atraumatic design of catheters driven using magnetic fields may reduce the risk of patient harm and other adverse events. Performing the procedure from a control cockpit enables physicians to complete procedures in a safe location protected from x-ray exposure, with greater ergonomics, and improved efficiency. We believe these benefits can be applicable in other endovascular indications where navigation through complex vasculature is often challenging or unsuccessful and generates significant x-ray exposure, and we are investing in research and development in these areas.

Our primary products include the Genesis RMN System, the Odyssey Solution, and other related devices. Through our strategic relationships with fluoroscopy system manufacturers, providers of catheters and electrophysiology mapping systems, and other parties, we offer our customers x-ray systems and other accessory devices.

The Genesis RMN System is designed to enable physicians to complete more complex interventional procedures by providing image-guided delivery of catheters through the blood vessels and chambers of the heart to treatment sites. This is achieved using externally applied magnetic fields that govern the motion of the working tip of the catheter, resulting in improved navigation, efficient procedures, and reduced x-ray exposure.

The Odyssey Solution consolidates lab information onto one large integrated display, enabling physicians to view and control all the key information in the operating room. This is designed to improve lab layout and procedure efficiency. The system also features a remote viewing and recording capability called Odyssey Cinema, which is an innovative solution that delivers synchronized content for optimized workflow, advanced care, and improved productivity. This tool includes an archiving capability that allows clinicians to store and replay entire procedures or segments of procedures. This information can be accessed from locations throughout the hospital local area network and over the global Odyssey Network providing physicians with a tool for clinical collaboration, remote consultation, and training.

We have arrangements with fluoroscopy system manufacturers to provide such systems in a bundled purchase offer for hospitals establishing robotic interventional operating rooms. These are single-plane, full-power x-ray systems and include the c-arm and powered table. The combination of RMN Systems with our partnered x-ray systems reduces the cost of acquisition, the ongoing cost of ownership, and the complexity of installation of a robotic electrophysiology practice.

We promote our full suite of products in a typical hospital implementation, subject to regulatory approvals or clearances. This implementation requires a hospital to agree to an upfront capital payment and recurring payments. The upfront capital payment typically includes equipment and installation charges. The recurring payments typically include disposable costs for each procedure, equipment service costs beyond the warranty period, and ongoing software updates. In hospitals where our full suite of products has not been implemented, equipment upgrade or expansion can be implemented upon purchasing of the necessary upgrade or expansion.

We have received regulatory clearances and approvals necessary for us to market the Genesis RMN System in the U.S. and Europe, and we are in the process of obtaining necessary registrations for extending our markets in other countries. The Niobe System, our prior generation robotic magnetic navigation system, the Odyssey Solution, Cardiodrive, e-Contact, and various disposable interventional devices have received regulatory clearances and approvals in the U.S., Europe, Canada, China, Japan and various other countries. We have received the regulatory clearances and approvals that allow us to market the Vdrive and Vdrive Duo Systems with the V-CAS device in the U.S. and Canada. We are pursuing regulatory approvals for the Stereotaxis MAGiC catheter, a robotically-navigated magnetic ablation catheter designed to perform minimally invasive cardiac ablation procedures, in various global geographies. Approval processes can be lengthy and uncertain, submissions may require revised or additional non-clinical and clinical data, and regulatory applications could be denied.

We have strategic relationships with technology leaders and innovators in the global interventional market. Through these strategic relationships we provide compatibility between our robotic magnetic navigation system, x-ray systems, and digital imaging and 3D catheter location sensing technology, as well as disposable interventional devices. The maintenance of these strategic relationships, or the establishment of equivalent alternatives, is critical to our commercialization efforts. There are no guarantees that any existing strategic relationships will continue, and efforts are ongoing to ensure the availability of compatible systems and devices and/or equivalent alternatives. We cannot provide assurance as to the timeline of the ongoing availability of such compatible systems or our ability to obtain equivalent alternatives on competitive terms or at all.

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited financial statements of Stereotaxis, Inc. have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and the instructions to Form 10-Q. Accordingly, they do not include all the disclosures required by GAAP for complete financial statements. In the opinion of management, they include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results for the interim periods presented. Operating results for the three-month period ended March 31, 2024, are not necessarily indicative of the results that may be expected for the year ending December 31, 2024, or for future operating periods.

These interim financial statements and the related notes should be read in conjunction with the annual financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, as filed with the Securities and Exchange Commission (SEC) on March 8, 2024.

Risks and Uncertainties

Future results of operations could be materially adversely impacted by macroeconomic and geopolitical factors. The Company continues to experience difficulties with periodic worldwide supply chain disruptions, including shortages and inflationary pressures, and logistics delays which make it difficult for us to source parts and ship our products. We have generally been able to conduct normal business activities albeit in a more deliberate manner than prior to the pandemic, including taking action to increase inventory levels and engaging in discussions with our vendors on contractual obligations, but we cannot guarantee that they will not be impacted more severely in the future. Our suppliers and contract manufacturers have experienced, and may continue to experience, similar difficulties. If our manufacturing operations or supply chains are materially interrupted, it may not be possible for us to timely manufacture or service our products at required levels, or at all. Changes in economic conditions and supply chain constraints could lead to higher inflation than previously experienced or expected, which could, in turn, lead to an increase in costs. We may be unable to raise the prices of our products sufficiently to keep up with the rate of inflation. A material reduction or interruption in any of our manufacturing processes or a substantial increase in costs would have a material adverse effect on our business, operating results, and financial condition.

Many of our hospital customers, for whom the purchase of our system involves a significant capital purchase which may be part of a larger construction project at the customer site (typically the construction of a new building), may themselves be under economic pressures. Hospitals continue to experience challenges with staffing and cost pressures as supply chain constraints and inflation drive up operating costs. This may cause delays or cancellations of current purchase orders and other commitments and may exacerbate the long and variable sales and installation cycles for our robotic magnetic navigation systems. Our hospital customers have also experienced challenges in sourcing supplies, such as catheters, needed to perform procedures. Such shortages have, and may continue to, put pressure on procedures and our disposable revenue.

Any disruption to the capital markets could negatively impact our ability to raise capital. If the capital markets are disrupted for an extended period of time and we need to raise additional capital, such capital may not be available on acceptable terms, or at all. Disruptions to the capital markets and other financing sources could also negatively impact our hospital customers’ ability to raise capital or otherwise obtain financing to fund their operations and capital projects. Such could result in delayed spending on current projects, a longer sales cycle for new projects where a large capital commitment is required, and decreased demand for our disposable products as well as an increased risk of customer defaults or delays in payments for our system installations, service contracts and disposable products.

In addition to the aforementioned macroeconomic factors, the COVID-19 pandemic negatively affected, and any resurgence of a variant of COVID-19 or any similar occurrences may in the future negatively affect demand for both our systems and our disposable products. In the past, we have experienced business disruptions, including travel restrictions on us and our third-party distributors, which negatively affected our complex sales, marketing, installation, distribution and service network relating to our products and services. We also experienced reductions in demand for our disposable products as our healthcare customers (physicians and hospitals) re-prioritized the treatment of patients and diverted resources away from non-coronavirus areas, leading to the performance of fewer procedures in which our disposable products are used. Significant decreases to our capital or recurring revenues could have a material adverse effect on our business, operating results, and financial condition. While we cannot reliably estimate the ultimate duration of the impact or the severity of ongoing periodic resurgences of pandemic-related issues, we continue to anticipate periodic disruptions to our manufacturing operations, supply chains, procedures volumes, service activities, and capital system orders and placements, any of which could have a material adverse effect on our business, financial condition, results of operations, or cash flows. The impact has varied widely over time by individual geography.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentration of credit risk consist of cash, cash equivalents and marketable securities. Our investments may include, at any time, a diversified portfolio of cash equivalents and short- and long-term investments in a variety of high-quality securities, including money market funds, U.S. treasury and U.S. government agency securities, corporate notes and bonds, commercial paper, non-U.S. government agency securities, and municipal notes. The Company’s exposure to any individual corporate entity is limited by policy. Deposits may exceed federally insured limits, and the Company is exposed to credit risk on deposits in the event of default by the financial institutions to the extent account balances exceed the amount insured by the Federal Deposit Insurance Corporation (FDIC). The Company closely monitors events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions or other companies in the financial services industry or the financial services industry generally, including Silicon Valley Bank. On March 10, 2023, Silicon Valley Bank (“SVB”), where the Company maintained accounts with a cash balance of less than 6% of the Company’s total cash, cash equivalents and marketable securities, was closed by the California Department of Financial Protection and Innovation and the FDIC was appointed as receiver. On March 12, 2023, the U.S. Department of the Treasury, Federal Reserve Board, and FDIC released a joint statement announcing that the FDIC would complete its resolution of SVB in a manner that fully protected all depositors at SVB and that depositors would have access to all of their money starting March 13, 2023. On March 26, 2023, it was announced that First-Citizens Bank & Trust Company would assume all of SVB’s deposits and loans as of March 27, 2023. During the periods presented, the Company has not experienced any losses on its deposits of cash, cash equivalents or marketable securities.

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand, money market instruments, and other highly liquid investments with original maturities of three months or less from the date of purchase. Accrued interest receivable on money market instruments, included in other current assets, was less than $0.1 million as of March 31, 2024, and December 31, 2023.

Restricted Cash

Restricted cash primarily consists of cash that the Company is obligated to maintain in accordance with contractual obligations. The Company’s restricted cash was $0.6 million and $0.7 million as of March 31, 2024, and December 31, 2023, respectively.

Investments

Our investments may include, at any time, a diversified portfolio of cash equivalents and short-and long-term investments in a variety of high-quality securities, including money market funds, U.S. treasury and U.S. government agency securities, corporate notes and bonds, commercial paper, non-U.S. government agency securities, and municipal notes. As of March 31, 2024, and December 31, 2023, the Company had no short-term investments.

Amortized cost of U.S. treasury securities and marketable debt securities are based on the Company’s purchase price adjusted for accrual of discount, or amortization of premium, and recognition of impairment charges, if any. The amortized cost of securities the Company purchases at a discount or premium will equal the face or par value at maturity or the call date, if applicable. Stated interest on investments is reported as income when earned and is adjusted for amortization or accretion of any premium or discount.

The Company segments its portfolio based on the underlying risk profiles of the securities and has a zero-loss expectation for U.S. treasury and U.S. government agency securities. The Company regularly reviews the securities using the probability of default method and analyzes the unrealized loss positions and evaluates the current expected credit loss by considering factors such as credit ratings, issuer-specific factors, current economic conditions, and reasonable and supportable forecasts. The Company did not have any material expected credit losses on investments or material expected credit losses on accrued interest related to investments during the three months ended March 31, 2024, or year ended December 31, 2023.

Fair Value Measurements

Financial instruments consist of cash and cash equivalents, restricted cash, investments, accounts receivable, and accounts payable.

The Company measures certain financial assets and liabilities at fair value on a recurring basis. General accounting principles for fair value measurement establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities (“Level 1”) and the lowest priority to unobservable inputs (“Level 3”). The three levels of the fair value hierarchy are described below:

Level 1:		Values are based on unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

Level 2:		Values are based on quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, or other model-based valuation techniques for which all significant assumptions are observable in the market.

Level 3:		Values are generated from model-based techniques that use significant assumptions not observable in the market.

As of March 31, 2024, and December 31, 2023, financial assets classified as Level 2 consisted of money market funds. The Company reviews trading activity and pricing for these investments as of the measurement date. When sufficient quoted pricing for identical securities is not available, the Company uses market pricing and other observable market inputs for similar securities. These inputs either represent quoted prices for similar assets in active markets or have been derived from observable market data. This approach results in the Level 2 classification of these securities within the fair value hierarchy.

Accounts Receivable, Contract Assets, and Allowance for Credit Losses

Accounts receivable primarily include amounts due from hospitals and distributors for acquisition of magnetic systems, associated disposable device sales and service contracts, net of allowances for expected credit losses. Credit is granted on a limited basis, with balances due generally within 30 days of billing. Contract assets primarily represent the difference between the revenue that was earned but not billed on service contracts and revenue from system contracts that was recognized based on the relative selling price of the related performance obligations and the contractual billing terms in the arrangements. The Company reports accounts receivable and contract assets net of an allowance for expected credit losses in accordance with Accounting Standards Codification Topic 326, Financial Instruments – Credit Losses (“ASC 326”). The provision for credit loss is based upon management’s assessment of historical and expected net collections considering business and economic conditions and other collection indicators. We assess collectability by reviewing the accounts receivable aging schedule on an aggregated basis where similar characteristics exist and on an individual basis when we identify specific customers with known disputes or collectability issues. Amounts deemed uncollectible are recorded as an allowance for expected credit losses.

Revenue and Costs of Revenue

The Company accounts for revenue in accordance with Accounting Standards Codification Topic 606 (“ASC 606”), Revenue from Contracts with Customers.

We generate revenue from the initial capital sales of systems as well as recurring revenue from the sale of our proprietary disposable devices, from royalties paid to the Company on the sale of various devices as provided by co-development and co-placement arrangements, and from other recurring revenue including ongoing software updates and service contracts.

We account for a contract with a customer when there is a legally enforceable contract between the Company and the customer, the rights of the parties are identified, the contract has commercial substance, and collectability of the contract consideration is probable. We record our revenue based on consideration specified in the contract with each customer, net of any taxes collected from customers that are remitted to government authorities.

For contracts containing multiple products and services, the Company accounts for individual products and services as separate performance obligations if they are distinct, which is if a product or service is separately identifiable from other items in the bundled package, and if a customer can benefit from it on its own or with other resources that are readily available to the customer. The Company recognizes revenues as the performance obligations are satisfied by transferring control of the product or service to a customer.

For arrangements with multiple performance obligations, revenue is allocated to each performance obligation based on its relative standalone selling price. Standalone selling prices are based on observable prices at which the Company separately sells the products or services. If a standalone selling price is not directly observable, then the Company estimates the standalone selling price considering market conditions and entity-specific factors including, but not limited to, features and functionality of the products and services and market conditions. The Company regularly reviews standalone selling prices and updates these estimates if necessary.

Our revenue recognition policy affects the following revenue streams in our business as follows:

Systems:

Contracts related to the sale of systems typically contain separate obligations for the delivery of system(s), installation, service-type warranty, and an implied obligation to provide software enhancements if and when available for one year following installation. Revenue is recognized when the Company transfers control to the customer, which is generally at the point when acceptance occurs that indicates customer acknowledgment of delivery or installation, depending on the terms of the arrangement. Revenue from service-type warranties and the implied obligation to deliver software enhancements if and when available is included in Other Recurring Revenue and is recognized ratably typically over the first year following installation of the system as the customer receives the service-type warranty and right to software updates throughout the period. The Company’s system contracts generally do not provide a right of return. Systems are generally covered by a one-year service-type warranty or a one-year assurance-type warranty. Assurance-type warranty costs were less than $0.1 million for the three months ended March 31, 2024, and 2023. Revenue from system delivery and installation represented 38% and 28% of revenue for the three months ended March 31, 2024, and 2023, respectively.

Disposables:

Revenue from sales of disposable products is recognized when control is transferred to the customers, which generally occurs at the time of shipment, but can also occur at the time of delivery depending on the customer arrangement. Disposable products are covered by an assurance type warranty that provides for the return of defective products. Warranty costs were not material for the three months ended March 31, 2024, and 2023. Disposable revenue represented 21% and 24% of revenue for the three months ended March 31, 2024, and 2023, respectively.

Royalty:

The Company receives royalties on the sale of various devices as provided by co-development and co-placement arrangements with various manufacturers. Royalty revenue represented less than 1% of revenue for the three months ended March 31, 2024, and 2023.

Other Recurring Revenue:

Other recurring revenue includes revenue from product maintenance plans, service-type warranties, other post warranty maintenance, and the implied obligation to provide software enhancements if and when available for a specified period, typically one year following installation of our systems. Revenue from services and software enhancements, service-type warranties, and the implied obligation to provide software enhancements are deferred and amortized over the service or update period, which is typically one year. Revenue related to services performed on a time-and-materials basis is recognized when performed. Other recurring revenue represented 41% and 48% of revenue for the three months ended March 31, 2024, and 2023, respectively.

The following table summarizes the Company’s revenue for systems, disposables, and service and accessories for the three months ended March 31, 2024, and 2023 (in thousands):

	2024		2023
	Three Months Ended March 31,
	2024		2023
Systems	$	2,612	$	1,821
Disposables, service and accessories		4,268		4,727
Total revenue	$	6,880	$	6,548

Transaction price allocated to remaining performance obligations relates to amounts allocated to products and services for which the revenue has not yet been recognized. A significant portion of this amount relates to the Company’s systems contracts and obligations that will be recognized as revenue in future periods. These obligations are generally satisfied within two years after contract inception but may occasionally extend longer. Transaction price representing revenue to be earned on remaining performance obligations on system contracts was approximately $11.9 million as of March 31, 2024. Performance obligations arising from contracts for disposables and service are generally expected to be satisfied within one year after entering into the contract.

The following table summarizes the Company’s contract assets and liabilities (in thousands):

	March 31, 2024			December 31, 2023
Contract Assets - unbilled receivables	$	77		$	72

Customer deposits	$	1,850		$	2,105
Product shipped, revenue deferred		1,509			1,413
Deferred service and license fees		4,160			4,776
Total deferred revenue	$	7,519		$	8,294
Less: Long-term deferred revenue		(1,581	)		(1,637	)
Total current deferred revenue	$	5,938		$	6,657

The Company invoices its customers based on the billing schedules in its sales arrangements. Contract assets primarily represent the difference between the revenue that was earned but not billed on service contracts and revenue from system contracts that was recognized based on the relative selling price of the related performance obligations and the contractual billing terms in the arrangements. Customer deposits primarily relate to future system sales but can also include deposits on disposable sales. Deferred revenue is primarily related to service contracts, for which the service fees are billed up-front, generally quarterly or annually, and for amounts billed in advance for system contracts for which some performance obligations remain outstanding. For service contracts, the associated deferred revenue is generally recognized ratably over the service period. For system contracts, the associated deferred revenue is recognized when the remaining performance obligations are satisfied. The Company did not have any impairment losses on its contract assets for the periods presented.

Revenue recognized for the three months ended March 31, 2024, and 2023, that was included in the deferred revenue balance at the beginning of each reporting period was $3.0 million.

Assets Recognized from the Costs to Obtain a Contract with a Customer

The Company has determined that sales incentive programs for the Company’s sales team meet the requirements to be capitalized as the Company expects to generate future economic benefits from the related revenue generating contracts after the initial capital sales transaction. The costs capitalized as contract acquisition costs included in prepaid expenses and other assets, in the Company’s balance sheet were $0.1 million as of March 31, 2024, and December 31, 2023. The Company did not incur any impairment losses during any of the periods presented.

Costs of systems revenue include direct product costs, installation labor and other costs including estimated assurance-type warranty costs, and initial training costs, when applicable. These costs are recognized at the time of sale. Costs of disposable revenue include direct product costs and estimated warranty costs and are recognized at the time of sale. Cost of revenue from services and license fees are recognized when incurred.

Leasing Arrangements

A lease is defined as a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. The Company accounts for leases in accordance with Accounting Standards Update No. 2016-02 “Leases” (Topic 842) and all subsequent ASUs that modified Topic 842 (“ASC 842”). The Company determines if an arrangement contains a lease at inception.

The Company leases its facilities under operating leases. In accordance with ASC 842, operating lease agreements are recognized on the balance sheet as a right-of-use (“ROU”) asset and a corresponding lease liability. These leases generally do not have significant rent escalation holidays, concessions, leasehold improvement incentives, or other build-out clauses. Further, the leases do not contain contingent rent provisions. Many of our leases include both lease (i.e., fixed payments including rent, taxes, and insurance costs) and non-lease components (i.e., common-area or other maintenance costs) which are accounted for as a single lease component as we have elected the practical expedient to group lease and non-lease components for all leases.

The Company’s lease agreements often include one or more options to renew at the Company’s discretion. If at lease inception, the Company considers the exercising of a renewal option to be reasonably certain, the Company will include the extended term in the calculation of the ROU asset and lease liability. The Company elected not to include short-term leases (i.e., leases with initial terms of twelve months or less) on the balance sheet.

The calculated amounts of the ROU assets and lease liabilities are impacted by the length of the lease term and the discount rate used to calculate the present value of the minimum lease payments. ASC 842 requires the use of the discount rate implicit in the lease whenever this rate is readily determinable. As this rate is rarely determinable, the Company utilizes its incremental borrowing rate at lease inception.

Stock-Based Compensation

The Company accounts for its grants of stock options, non-qualified stock options, stock appreciation rights, restricted shares, restricted stock units and for its employee stock purchase plan in accordance with the provisions of general accounting principles for share-based payments. These accounting principles require the determination of the fair value of the stock-based compensation at the grant date and the recognition of the related expense over the period in which the stock-based compensation vests.

For time-based awards, the Company utilizes the Black-Scholes valuation model to determine the fair value of stock options and stock appreciation rights at the date of grant. The weighted average assumptions and fair value for options granted during the three months ended March 31, 2024, were 1) expected dividend rate of 0%; 2) expected volatility of 76% based on the Company’s historical volatility; 3) risk-free interest rate based on the Treasury yield on the date of grant; and 4) expected term of 6.25 years. The resulting compensation expense is recognized over the requisite service period, which is generally four years. Restricted shares and units granted to employees and non-employee directors are valued at the fair market value at the date of grant. The Company amortizes the fair market value to expense over the service period, which is generally four years except for grants to directors which are generally earned over a period of six months. If the shares are subject to performance objectives, the resulting compensation expense is amortized over the anticipated vesting period and is subject to adjustment based on the actual achievement of objectives.

For market-based awards, stock-based compensation expense is recognized over the minimum service period regardless of whether or not the market target is probable of being achieved. The fair value of such awards is estimated on the grant date using Monte Carlo simulations.

Shares purchased by employees under the 2022 Employee Stock Purchase Plans are considered to be non-compensatory.

Net Loss per Common Share

Basic earnings (loss) per common share is computed by dividing the net earnings (loss) for the period by the weighted average number of common shares outstanding during the period. In periods where there is net income, we apply the two-class method to calculate basic and diluted net income (loss) per share of common stock, as our convertible preferred stock is a participating security. The two-class method is an earnings allocation formula that treats a participating security as having rights to earnings that otherwise would have been available to common stockholders. In periods where there is a net loss, the two-class method of computing earnings per share does not apply as our convertible preferred stock does not contractually participate in our losses. We compute diluted net income (loss) per common share using net income (loss) as the “control number” in determining whether potential common shares are dilutive, after giving consideration to all potentially dilutive common shares, including stock options, warrants, unvested restricted stock units outstanding during the period and potential issuance of stock upon the conversion of our convertible preferred stock issued and outstanding during the period, except where the effect of such securities would be antidilutive.

The following table sets forth the computation of basic and diluted EPS (in thousands except for share and per share amounts):

	2024			2023
	Three Months Ended March 31,
	2024			2023
Net loss	$	(4,507	)	$	(5,347	)
Cumulative dividend on convertible preferred stock		(331	)		(331	)
Net loss attributable to common stockholders	$	(4,838	)	$	(5,678	)

Weighted average number of common shares and equivalents:		83,476,498			76,500,965
Basic EPS	$	(0.06	)	$	(0.07	)
Diluted EPS	$	(0.06	)	$	(0.07	)

The Company did not include any portion of unearned restricted shares, outstanding options, stock appreciation rights, warrants or convertible preferred stock in the calculation of diluted loss per common share because all such securities are anti-dilutive for all periods presented. The application of the two-class method of computing earnings per share under general accounting principles for participating securities is not applicable during these periods because those securities do not contractually participate in its losses.

As of March 31, 2024, the Company had 3,470,733 shares of common stock issuable upon the exercise of outstanding options and stock appreciation rights at a weighted average exercise price of $3.92 per share, 48,885,547 shares of our common stock issuable upon conversion of our Series A Convertible Preferred Stock and 1,741,741 shares of unvested restricted share units. The Company had no unearned restricted shares outstanding as of March 31, 2024.

Recently Issued Accounting Pronouncements

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments” and also issued subsequent amendments to the initial guidance under ASU 2018-19, ASU 2019-04 and ASU 2019-05. The standard modifies the measurement approach for credit losses on financial instruments, including trade receivables, from an incurred loss method to a current expected credit loss method, otherwise known as “CECL.” The standard requires the measurement of expected credit losses to be based on relevant information, including historical experience, current conditions and a forecast that is supportable. The Company adopted the standard in the first quarter of 2023. The impact to the Company’s financial results was immaterial.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”), which requires enhanced income tax disclosures, primarily related to the effective tax rate reconciliation and income taxes paid. The Company does not expect a significant impact on its income tax disclosures upon adoption of the ASU which will be effective in the Company’s year ending December 31, 2025.

9. Convertible Preferred Stock and Stockholders’ Equity

The holders of common stock are entitled to one vote for each share held and to receive dividends when and as declared by the Board of Directors out of funds legally available for dividends, subject to the prior rights or preferences applicable to any preferred stock as may then be outstanding. No dividends have been declared or paid as of March 31, 2024, and the Company does not presently intend to pay any cash dividends in the foreseeable future.

Series A Convertible Preferred Stock and Warrants

In September 2016, the Company issued (i) 24,000 shares of Series A Convertible Preferred Stock (the “Series A Preferred Stock”), par value $0.001 per share, with a stated value of $1,000 per share, which are convertible into shares of the Company’s common stock at an initial conversion rate of $0.65 per share, subject to adjustment for events such as stock splits, combinations and the like as provided in the certificate of designations covering such Series A Preferred Stock, and (ii) (the SPA Warrants) to purchase an aggregate of 36,923,078 shares of common stock. The shares of Series A Preferred Stock are entitled to vote on an as-converted basis with the common stock, subject to specified beneficial ownership issuance limitations. The Series A Preferred Stock bear dividends at a rate of six percent (6%) per annum, which are cumulative and accrue daily from the date of issuance on the $1,000 stated value. Such dividends will not be paid in cash except in connection with any liquidation, dissolution or winding up of the Company or any redemption of the Series A Preferred Stock. Each holder of convertible preferred shares has the right to require us to redeem such holder’s shares of Series A Preferred Stock upon the occurrence of specified events, which include certain business combinations, the sale of all or substantially all of the Company’s assets, or the sale of more than 50% of the outstanding shares of the Company’s common stock. In addition, the Company has the right to redeem the Series A Preferred Stock in the event of a defined change of control. The Series A Preferred Stock ranks senior to our common stock as to distributions and payments upon the liquidation, dissolution, and winding up of the Company. Since the Series A Preferred Stock are subject to conditions for redemption that are outside the Company’s control, the Series A Preferred Stock are presently reported in the mezzanine section of the balance sheet.

2021 CEO Performance Award Unit Grant

On February 23, 2021, the Company`s Board of Directors, upon recommendation of the Compensation Committee, approved the grant of the CEO Performance Award to the Company’s Chief Executive Officer. The CEO Performance award is a 10-year performance award of up to 13,000,000 shares, tied to the achievement of market capitalization milestones and subject to minimum service requirements.

As detailed in the table below, the CEO Performance Award consists of ten vesting tranches. The first market capitalization milestone is $1.0 billion, and each of the remaining nine market capitalization milestones are in additional $500 million increments, up to $5.5 billion.

Tranche #	No. of Shares Subject to PSU		Market Capitalization Milestones⁽¹⁾
1		1,000,000	$	1,000,000,000
2		1,500,000	$	1,500,000,000
3		1,500,000	$	2,000,000,000
4		2,000,000	$	2,500,000,000
5		1,000,000	$	3,000,000,000
6		1,000,000	$	3,500,000,000
7		1,000,000	$	4,000,000,000
8		2,000,000	$	4,500,000,000
9		1,000,000	$	5,000,000,000
10		1,000,000	$	5,500,000,000
Total:		13,000,000

Each tranche represents a portion of the PSUs covering the number of shares outlined in the table above. Each tranche vests upon (i) satisfaction of the market capitalization milestones and (ii) continued employment as CEO of the Company from the grant date through December 31, 2030. Absent an earlier termination, the PSUs will expire on December 31, 2030. If our CEO ceases employment as CEO of the Company for any reason including death, disability, termination for cause or without cause (as defined in the award agreement), or if he voluntary terminates after service as CEO for at least five years, the remaining service period will be waived and he will retain any PSUs that have vested through the date of termination.

The Company received Shareholder approval at its annual meeting on May 20, 2021, for shares to be issued under the award.

The market capitalization requirement is considered a market condition under FASB Accounting Standards Codification Topic 718 “Compensation – Stock Compensation” and is estimated on the grant date using Monte Carlo simulations. Recognition of stock-based compensation expense of all the tranches commenced on February 23, 2021, the date of grant, as the probability of meeting the ten market capitalization milestones is not considered in determining the timing of expense recognition. The expense will be recognized on an accelerated basis through 2030. Key assumptions for estimating the performance-based awards fair value at the date of grant included share price on grant date, volatility of the Company’s common stock price, risk free interest rate, and grant term.

Total stock-based compensation recorded as operating expense for the CEO Performance Award was $1.8 million for the three months ended March 31, 2024, and 2023. As of March 31, 2024, and 2023, the Company had approximately $35.2 million and $42.4 million, respectively, of total unrecognized stock-based compensation expense remaining under the CEO Performance Award assuming the grantee’s continued employment as CEO of the Company, or in a similar capacity, through 2030. As of March 31, 2024, none of the performance milestones established by the 2021 CEO Incentive Program have been achieved, and no awards have been earned.

Stock Award Plans

In February 2022, the Compensation Committee of the Board of Directors adopted the 2022 Stock Incentive Plan (the “Plan”) which was subsequently approved by the Company’s shareholders. This plan replaced the 2012 Stock Incentive Plan which expired on May 19, 2022. The 2022 Stock Incentive Plan allows for the grant of incentive stock options, non-qualified stock options, stock appreciation rights, restricted shares and restricted share units to employees, non-employee directors, and third-party consultants.

At March 31, 2024, the Company had 2,297,196 remaining shares of the Company’s common stock to provide for current and future grants under its various equity plans.

At March 31, 2024, the total compensation cost related to options and non-vested stock granted to employees and non-employees under the Company’s stock award plans but not yet recognized was approximately $3.0 million, excluding compensation not yet recognized related to the CEO Performance Award discussed above. This cost will be amortized over a period of up to four years over the underlying estimated service periods and will be adjusted for subsequent changes in actual forfeitures and anticipated vesting periods.

A summary of the option and stock appreciation rights activity for the three-month period ended March 31, 2024, is as follows:

	Number of Options/SARs			Range of Exercise Price		Weighted Average Exercise Price per Share

10. Product Warranty Provisions

The Company’s standard policy is to warrant all capital systems against defects in material or workmanship for one year following installation. The Company’s estimate of costs to service the warranty obligations is based on historical experience and current product performance trends. A regular review of warranty obligations is performed to determine the adequacy of the reserve and adjustments are made to the estimated warranty liability as appropriate.

Accrued warranty, which is included in other accrued liabilities, consists of the following (in thousands):

Schedule of Accrued Warranty

	March 31, 2024			December 31, 2023
Warranty accrual, beginning of the fiscal period	$	107		$	163
Accrual adjustment for product warranty		(1	)		547
Payments made		(16	)		(603	)
Warranty accrual, end of the fiscal period	$	90		$	107

11. Commitments and Contingencies

The Company at times becomes a party to claims in the ordinary course of business. Management believes that the ultimate resolution of pending or threatened proceedings will not have a material effect on the financial position, results of operations or liquidity of the Company. In February 2024, a vendor filed financing statements under the Uniform Commercial Code (“UCC”) on underlying inventory for approximately $0.6 million. We believe the financing statements were filed without merit, and we fully intend on contesting the propriety of such actions.

In April 2021, the Company entered into a letter of credit pursuant to the Lease agreement totaling approximately $1.8 million to be delivered in four equal installments of which the first was delivered in April 2021, the second was delivered in July 2021, the third was delivered in October 2021, and the fourth was delivered in January 2022. The amount available under this letter of credit automatically reduces by one fortieth at the end of each month during the lease term.

12. Subsequent Events

On May 11, 2024, the Company entered into a definitive share purchase agreement to acquire all of the outstanding equity capital stock of Access Point Technologies, Inc., a privately-held Minnesota-based developer of innovative electrophysiology catheters, for $3.0 million of Company common stock at closing and, in addition, Company common stock contingently issuable over five years after closing upon achieving certain key regulatory and commercial milestones. The acquisition is expected to close by the end of the third quarter of 2024 subject to customary closing conditions.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures. We review our estimates and judgments on an on-going basis. We base our estimates and judgments on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from these estimates. We believe the following accounting policies are critical to the judgments and estimates we use in preparing our financial statements. For a complete listing of our critical accounting policies, please refer to our Annual Report on Form 10-K for the year ended December 31, 2023.

Revenue Recognition

In accordance with Accounting Standards Codification Topic 606 (“ASC 606”), “Revenue from Contracts with Customers,” we account for a contract with a customer when there is a legally enforceable contract between the Company and the customer, the rights of the parties are identified, the contract has commercial substance, and collectability of the contract consideration is probable. We record our revenue based on consideration specified in the contract with each customer, net of any taxes collected from customers that are remitted to government authorities.

For contracts containing multiple products and services the Company accounts for individual products and services as separate performance obligations if they are distinct, which is if a product or service is separately identifiable from other items in the bundled package, and if a customer can benefit from it on its own or with other resources that are readily available to the customer. The Company recognizes revenues as the performance obligations are satisfied by transferring control of the product or service to a customer.

Systems:

Disposables:

Royalty:

The Company receives royalties on the sale of various devices as provided by co-development and co-placement arrangements with various manufacturers.

Other Recurring Revenue:

The Company invoices its customers based on the billing schedules in its sales arrangements. Contract assets primarily represent the difference between the revenue that was recognized based on the relative selling price of the related performance obligations and the contractual billing terms in the arrangements. Customer deposits primarily relate to future system sales but can also include deposits on disposable sales. Deferred revenue is primarily related to service contracts, for which the service fees are billed up-front, generally quarterly or annually, and for amounts billed in advance for system contracts for which some performance obligations remain outstanding. For service contracts, the associated deferred revenue is generally recognized ratably over the service period. For system contracts, the associated deferred revenue is recognized when the remaining performance obligations are satisfied. See Note 2 for additional detail on deferred revenue. The Company did not have any impairment losses on its contract assets for the periods presented.

Assets Recognized from the Costs to Obtain a Contract with a Customer

The Company has determined that sales incentive programs for the Company’s sales team meet the requirements to be capitalized as the Company expects to generate future economic benefits from the related revenue generating contracts after the initial capital sales transaction. The costs capitalized as contract acquisition costs included in prepaid expenses and other assets in the Company’s balance sheets were $0.1 million as of March 31, 2024, and December 31, 2023. The Company did not incur any impairment losses during any of the periods presented.

Cost of Contracts

Costs of systems revenue include direct product costs, installation labor and other costs including estimated assurance-type warranty costs and initial training costs, when applicable. These costs are recognized at the time of sale. Costs of disposable revenue include direct product costs and estimated warranty costs and are recognized at the time of sale. Cost of revenue from services and license fees are recognized when incurred.

Stock-Based Compensation

Stock compensation expense, which is a non-cash charge, results from stock option, non-qualified stock options, stock appreciation rights, and restricted share grants made to employees, non-employee directors, and third-party consultants at the fair value of the grants. For time-based awards, the fair value of options and stock appreciation rights granted was determined using the Black-Scholes valuation method which gives consideration to the estimated value of the underlying stock at the date of grant, the exercise price of the option, the expected dividend yield and volatility of the underlying stock, the expected life of the option and the corresponding risk-free interest rate. The fair value of the grants of restricted shares and units was determined based on the closing price of our stock on the date of grant. Stock compensation expense for options, stock appreciation rights and for time-based restricted share grants and units is amortized on a straight-line basis over the vesting period of the underlying issue, generally over four years except for grants to non-employee directors which are generally earned over a period of six months. Stock compensation expense for performance-based restricted shares, if any, is amortized on a straight-line basis over the anticipated vesting period and is subject to adjustment based on the actual achievement of objectives. Compensation expense is recognized only for those options expected to vest, net of actual forfeitures. Estimates of the expected life of options have been based on the average of the vesting and expiration periods, which is the simplified method under general accounting principles for share-based payments. Estimates of volatility utilized in calculating stock-based compensation have been prepared based on historical data. Actual experience to date has been consistent with these estimates.

The amount of compensation expense to be recorded in future periods may increase if we make additional grants of options, stock appreciation rights or restricted shares. The amount of expense to be recorded in future periods may decrease if the requisite service periods are not completed.

Results of Operations

Comparison of the Three Months Ended March 31, 2024, and 2023

Revenue. Revenue increased from $6.5 million for the three months ended March 31, 2023, to $6.9 million for the three months ended March 31, 2024, an increase of 5%. Revenue from the sales of systems increased to $2.6 million for the three months ended March 31, 2024, from $1.8 million for the three months ended March 31, 2023, driven by increased system sales volumes and changes in product mix in the current year period. Revenue from sales of disposable interventional devices, service, and accessories decreased to approximately $4.3 million for the three months ended March 31, 2024, from $4.7 million for the three months ended March 31, 2023, a decrease of approximately 10%. The decrease was primarily driven by lower service revenue from time and material contracts in addition to lower current period disposable sales volumes related to Biosense Webster catheter shortages.

Cost of Revenue. Cost of revenue increased from $2.7 million for the three months ended March 31, 2023, to $2.9 million for the three months ended March 31, 2024, an increase of approximately 9%. As a percentage of our total revenue, overall gross margin remained fairly consistent at 58% for the three months ended March 31, 2024, compared to 59% for the three months ended March 31, 2023. Cost of revenue for systems sold increased to $1.9 million for the three months ended March 31, 2024, from $1.7 million for the three months ended March 31, 2023, driven by increased system sales volumes and changes in product mix in the current year period. Gross margin for systems was $0.7 million for the three months ended March 31, 2024, compared to $0.1 million for the three months ended March 31, 2023. Cost of revenue for disposables, service, and accessories remained consistent at $1.0 million for the three months ended March 31, 2023, and 2024. Gross margin for disposables, service, and accessories was 76% for the three months ended March 31, 2024, compared to 79% for the three months ended March 31, 2023.

Research and Development Expenses. Research and development expenses decreased from $2.7 million for the three months ended March 31, 2023, to $2.2 million for the three months ended March 31, 2024, a decrease of approximately 18%. This decrease was primarily driven by project timing and decreased headcount-related costs in the current year period, partially offset by higher clinical trial costs.

Sales and Marketing Expenses. Sales and marketing expenses decreased from $3.1 million for the three months ended March 31, 2023, to $3.0 million for the three months ended March 31, 2024, a decrease of approximately 5% primarily due to decreased headcount-related costs in the current year period.

General and Administrative Expenses. General and administrative expenses include finance, information systems, legal, and general management. General and administrative expenses decreased from $3.6 million for the three months ended March 31, 2023, to $3.5 million for the three months ended March 31, 2024, a decrease of approximately 4%. This decrease was driven by lower administrative and headcount-related costs in the current period.

Interest Income (Expense). Net interest income was approximately $0.2 million for the three months ended March 31, 2024, compared to approximately $0.3 million for the three months ended March 31, 2023. The decrease was driven by lower invested balances in the current year period.

Liquidity and Capital Resources

Liquidity refers to the liquid financial assets available to fund our business operations and pay for near-term obligations. These liquid financial assets consist of cash, cash equivalents, and investments.

As of March 31, 2024, we had $18.2 million of cash and cash equivalents, inclusive of restricted cash. We had working capital of $18.4 million as of March 31, 2024, compared to $20.0 million as of December 31, 2023.

The following table summarizes our cash flow by operating, investing and financing activities for the three months ended March 31, 2024, and 2023 (in thousands):

	Three Months Ended March 31,
	2024			2023
Cash flow used in operating activities	$	(2,346	)	$	(2,802	)
Cash flow used in investing activities		-			(349	)
Cash flow provided by financing activities		30			56

Net cash used in operating activities. We used approximately $2.3 million and $2.8 million of cash for operating activities during the three months ended March 31, 2024, and 2023, respectively. The decrease in cash used in operating activities was driven by the decrease in operating loss in the current year period partially offset by changes in working capital.

Net cash used in investing activities. We did not use any cash for investing activities during the three months ended March 31, 2024. We used approximately $0.3 million during the three months ended March 31, 2023, for the purchase of equipment, construction and design costs associated with our new facility.

Net cash provided by financing activities. We generated less than $0.1 million of cash from financing activities during the three months ended March 31, 2024, and 2023. The cash generated in both periods was driven by the proceeds from issuance of stock from the exercise of options, net of issuance costs, and from our employee stock purchase program.

Capital Resources

As of March 31, 2024, the Company did not have any debt.

Off-Balance Sheet Arrangements

We do not currently have, nor have we ever had, any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. In addition, we do not engage in trading activities involving non-exchange traded contracts. As a result, we are not materially exposed to any financing, liquidity, market, or credit risk that could have arisen if we had engaged in these relationships.

ITEM 3. [RESERVED]

None.

ITEM 4. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures: The Company’s management, with the participation of the Company’s Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the Company’s disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), as of the end of the period covered by this report. Any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on such evaluation, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of such period, the Company’s disclosure controls and procedures were effective.

Changes In Internal Control Over Financial Reporting: The Company’s management, with the participation of the Company’s Chief Executive Officer and Chief Financial Officer, also conducted an evaluation of the Company’s internal control over financial reporting to determine whether any changes occurred during the period covered by this report that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting. Based on that evaluation, there has been no such change during the period covered by this report.
