Stem and Nuvation Energy Enter into Agreement to Deliver North American-Made BESS Control SolutionApril 30, 2026 8:05 AM
Business Wire
Joint solution to combine Stem’s PowerTrack™ EMS Solution with Nuvation Energy’s BMS to help meet growing demand for secure, domestically sourced energy infrastructure
Stem, Inc. (NYSE: STEM), a global leader in AI-enabled clean energy software and services, today announced a co-marketing agreement with Nuvation Energy, a North American provider of battery management and energy control solutions, to jointly promote a fully North American-made battery energy storage system (BESS) control stack.
This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20260430823753/en/Stem and Nuvation Energy provide an integrated control stack, from cloud software through edge controls to the BESS and power conversion system
The agreement brings together Stem’s PowerTrack Energy Management System (EMS) and Unit Controller with Nuvation’s Battery Management System (BMS), creating an integrated control layer designed to meet growing demand for secure, compliant, and domestically sourced energy infrastructure. PowerTrack EMS provides site-level scheduling, utility dispatch, grid coordination, and edge-to-cloud telemetry, while Nuvation’s BMS delivers cell-level monitoring, protection, and state-of-charge optimization. Together, they create a more integrated and intelligent battery energy storage solution and a North American-designed and manufactured control solution.
“Customers are asking for greater transparency, control and confidence in the technologies deployed across their energy assets,” said Matt Tappin, President of Software at Stem. “This collaboration will allow us to deliver a more integrated solution that directly addresses those priorities, while enhancing system performance, reliability of the system, and long-term value for our customers.”
As regulatory requirements tighten across the United States, including Foreign Entity of Concern (FEOC) restrictions, and growing state-level legislation, developers and asset owners are actively seeking alternatives to control architectures that rely on foreign-manufactured or controlled components.
In response, some manufacturers are taking shortcuts to meet compliance thresholds, relying on rebranded products or minimally modified designs rather than investing in genuine North American engineering. These approaches may satisfy certain regulatory requirements while leaving critical safety and cybersecurity standards unaddressed.
“For developers, utilities, and project owners who need to get ahead of tightening compliance requirements, this solution is built to meet both the letter and the spirit of the law. By combining Nuvation's battery management system with Stem's energy management platform, we are delivering a solution where the critical control electronics are North American designed and manufactured, a clear and credible alternative that is technically robust and commercially relevant,” said Michael Worry, CEO/CTO at Nuvation Energy.
Nuvation Energy has been developing BMS technology since 2008, with products deployed across commercial, industrial, and utility-scale energy storage projects. All Nuvation solutions are developed and manufactured in the United States and Canada by a fully North American-based team.
Under the agreement, Stem and Nuvation will collaborate on a coordinated go-to-market strategy that includes joint thought leadership, trade show participation, and the development of co-branded collateral. The companies will also align their sales efforts, working together on identified opportunities, enabling closer commercial coordination, while preserving independent commercial structures.
The integrated solution will undergo joint performance validation and testing prior to customer deployment. Stem will lead EMS and system integration, including controls and telemetry across the BESS and power conversion system, while Nuvation will provide the BMS hardware and interfaces required for seamless integration.

Fourth Quarter and Full Year 2025 Financial and Operating Results
Financial Results
Fourth quarter 2025 revenue decreased 15% to $47.2 million, versus $55.8 million in the fourth quarter of 2024, as expected, due to significantly reduced battery hardware sales, attributable in part to the Company’s software-focused strategy introduced in 2024.
Full year 2025 revenue increased 8% to $156.3 million versus $144.6 million in full year 2024. Reported full year 2024 revenue reflects a $38.7 million reduction due to updated valuations in 2024 of certain contract guarantees for hardware revenue originally recorded in 2022 and 2023. Core revenue from software, services, and edge hardware was $141.4 million for full year 2025, up 25% from $113.2 million for the full year 2024.
Fourth quarter 2025 GAAP gross profit (loss) was $23.2 million, or 49%, versus $(2.5) million, or (4)%, in the fourth quarter of 2024. Full year 2025 GAAP gross profit (loss) was $60.0 million, or 38%, versus $(11.1) million, or (8)% for the full year 2024. The year-over-year increase in the fourth quarter and full year 2025 GAAP gross profit was due to increased higher-margin software, services, and edge hardware sales and significantly decreased lower-margin battery hardware sales.
Fourth quarter 2025 non-GAAP gross profit was $20.9 million, or 45%, versus $20.2 million, or 36%, in the fourth quarter of 2024. Full year 2025 non-GAAP gross profit was $72.3 million, or 46% versus full year 2024 non-GAAP gross profit of $63.7 million, or 35%. The increase in non-GAAP gross profit for the fourth quarter and full year 2025 was primarily due to increased higher-margin software, services, and edge hardware sales and decreased lower-margin battery hardware sales.
Fourth quarter 2025 net loss was $16.0 million versus fourth quarter 2024 net loss of $51.1 million. Full year 2025 net income was $137.8 million versus full year 2024 net loss of $854.0 million. The year-over-year change in net loss for the fourth quarter and full year of 2025 was primarily driven by a $220.0 million gain on extinguishment of debt in the second quarter of 2025, $104.1 million of bad debt expense associated with impairment of receivables related to customer contracts that provided a parent company guarantee in the third quarter of 2024, and a one-time, $547.2 million impairment of goodwill reported during the second quarter of 2024.
Fourth quarter 2025 adjusted EBITDA was $5.5 million, compared to $4.2 million in the fourth quarter of 2024. Full year 2025 adjusted EBITDA was $6.7 million compared to $(22.8) million in full year 2024. The year-over-year improvement in adjusted EBITDA for the fourth quarter and full year 2025 was primarily driven by improved margins and significantly lower operating expenses resulting from ongoing cost reduction and profitability improvement initiatives.
The Company ended the fourth quarter of 2025 with $48.9 million in cash and cash equivalents, as compared to $43.1 million in cash and cash equivalents at the end of the third quarter 2025.
Operating Results
Bookings were $32.7 million in the fourth quarter of 2025, compared to $37.6 million in the fourth quarter of 2024. The year-over-year decrease was primarily due to fewer battery hardware bookings, as a result of the strategic de-emphasis of battery hardware resales. Software, services, and edge hardware bookings increased 6% year-over-year. Full year 2025 bookings of $131.8 million increased 14% versus full year 2024 bookings of $115.9 million driven by increased software, services, and edge hardware bookings.
Contracted backlog was $21.3 million at the end of the fourth quarter of 2025, down 4% compared to $22.2 million as of the end of the third quarter of 2025 due to reduced battery hardware backlog, and up 2% versus $20.9 million as of the end of the fourth quarter of 2024.
CARR was $67.2 million at the end of the fourth quarter of 2025 versus $70.1 million as of the end of the third quarter of 2025. CARR decreased sequentially due to lower managed services bookings and the cancellation of a managed services customer engagement representing approximately $3 million in CARR but was supported by increased PowerTrack software bookings.
Fourth quarter 2025 ARR increased 1% sequentially to $61.1 million at the end of the quarter from $60.2 million at the end of the third quarter of 2025. ARR sequentially increased due to a 5% increase in PowerTrack ARR to $40.7 million but was offset by the cancellation of a managed services customer contract representing $1 million in ARR.
Solar operating AUM increased 6% sequentially to 36.1 GW for the fourth quarter. Storage operating AUM decreased 6% sequentially to 1.7 GWh for the quarter due to the cancellation of a managed services customer contract representing 0.1 GWh in AUM.
The following table provides a summary of contracted backlog at the end of the fourth quarter of 2025, and includes only hardware and non-recurring services contracts, compared to contracted backlog at the end of the third quarter of 2025 ($ millions):

See below for definitions.
Some Factors Affecting our Business and Operations
The Company is subject to risk and exposure from the evolving macroeconomic, regulatory, geopolitical and business environment, including uncertainty regarding the effects of the One Big Beautiful Bill (OBBB) on our business and that of our suppliers and customers, the effects of increased import tariffs and retaliatory trade policies, global inflationary pressures and interest rates, potential economic slowdowns or recessions, government shutdowns, and geopolitical pressures, including wars in Ukraine and the Middle East, as well as tensions between China and the United States, and uncertainty around other current and future trade policies and other regulations. We regularly monitor and attempt to mitigate the direct and indirect effects of these circumstances on our business and financial results, although there is no guarantee of the extent to which we will be successful in these efforts.
Use of Non-GAAP Financial Measures
In addition to financial results determined in accordance with U.S. generally accepted accounting principles (“GAAP”), this earnings press release contains the following non-GAAP financial measures: adjusted EBITDA, non-GAAP gross profit and non-GAAP gross margin.
We use these non-GAAP financial measures for financial and operational decision-making and to evaluate our operating performance and prospects, develop internal budgets and financial goals, and facilitate period-to-period comparisons. Management believes that these non-GAAP financial measures provide meaningful supplemental information regarding our performance and liquidity by excluding certain expenses and expenditures that may not be indicative of our operating performance, such as stock-based compensation and other non-cash charges, as well as discrete cash charges that are infrequent in nature. We believe that both management and investors benefit from referring to these non-GAAP financial measures in assessing our performance and when planning, forecasting, and analyzing future periods. These non-GAAP financial measures also facilitate management’s internal comparisons to our historical performance and liquidity as well as comparisons to our competitors’ operating results, to the extent that competitors define these metrics in the same manner that we do. We believe these non-GAAP financial measures are useful to investors both because they (1) allow for greater transparency with respect to key metrics used by management in its financial and operational decision-making and (2) are used by investors and analysts to help them analyze the health of our business. Our calculation of these non-GAAP financial measures may differ from similarly-titled non-GAAP measures, if any, reported by other companies. In addition, other companies may not publish these or similar measures. These non-GAAP financial measures should be considered in addition to, not as a substitute for, or superior to, other measures of financial performance prepared in accordance with GAAP. For reconciliation of adjusted EBITDA and non-GAAP gross profit and margin to their most comparable GAAP measures, see the section below entitled “Reconciliations of Non-GAAP Financial Measures.”
Definitions of Non-GAAP Financial Measures
We define adjusted EBITDA as net loss attributable to Stem before depreciation and amortization, including amortization of internally developed software, interest expense, further adjusted to exclude stock-based compensation and other income and expense items, including gain on the extinguishment of debt, reduction in revenue, excess supplier costs, change in fair value of derivative liability, change in fair value of warrant liability, impairment of goodwill, contract termination payment, restructuring costs, (expected recovery of) impairment of accounts receivable related to customer contracts that provided parent company guarantees, impairment of inventory and other deferred costs, impairment of deferred costs with suppliers, and income tax provision or benefit. The expenses and other items that we exclude in our calculation of adjusted EBITDA may differ from the expenses and other items, if any, that other companies exclude when calculating adjusted EBITDA.
We define non-GAAP gross profit (loss) as gross profit (loss) excluding amortization of capitalized software, impairments related to decommissioning of end-of-life systems, excess supplier costs, and reduction in revenue. Non-GAAP gross margin is defined as non-GAAP gross profit (loss) as a percentage of revenue.
In the year ended December 31, 2024, we incurred costs of $1.0 million above initially agreed prices on the acquisition of certain hardware systems from one of our suppliers, which resulted from production delays by such supplier. Because we had not previously incurred costs above initially agreed upon prices with a hardware supplier, we excluded this item from adjusted EBITDA and non-GAAP Gross Profit to better facilitate comparisons of our underlying operating performance across periods.
As previously disclosed, the Company entered into certain contractual guarantees in 2022 and 2023 pursuant to which, if a customer were unable to install or designate hardware to a specified project within a specified period of time, the Company would be required to assist the customer in re-marketing the hardware for resale by the customer. Such guarantees provided that, in such cases, if the customer resold the hardware for less than the amount initially sold to the customer, the Company would be required to compensate the customer for any shortfall in fair value for the hardware from the initial contract price. The Company accounted for specified contractual guarantees as variable consideration. As previously disclosed, the Company recorded a net revenue reduction of $38.7 million in hardware revenue during 2024, due to market conditions and revised negotiated valuations of assets under certain hardware price guarantees entered into in 2022 and 2023. Such reductions in revenue were related to deliveries that occurred prior to 2023. Additionally, the Company recorded a $104.1 million bad debt expense during the year ended December 31, 2024, as a result of an impairment of accounts receivable related to customer contracts that provided a parent company guarantee. The Company has not issued such guarantees since June 2023, does not intend to issue any new guarantees in the future, and does not expect further negative impact on its financial statements as a result of such guarantees.

Adjusted EBITDA, as used in the Company's full year 2026 guidance, is a non-GAAP financial measure that excludes or has otherwise been adjusted for items impacting comparability. The Company is unable to reconcile projected adjusted EBITDA to net income (loss), its most directly comparable forward-looking GAAP financial measure, without unreasonable effort, because the Company is unable to predict with a reasonable degree of certainty its change in stock-based compensation expense, depreciation and amortization expense, revenue constraint and other items that may affect net loss. The unavailable information could have a significant effect on the Company’s full year 2026 GAAP financial results.
(1)
Depreciation and amortization includes depreciation and amortization expense, impairment loss of energy storage systems, and impairment loss of project assets.
(2)
Refer to the discussion of revenue reduction under “Definitions of Non-GAAP Financial Measures” above.
(3)
Other revenue adjustments refer to terminations and modifications of significant contracts with customers prior to their scheduled termination dates.
(4)
Refer to the discussion of excess supplier costs under “Definitions of Non-GAAP Financial Measures” above.
(5)
Contract termination payments and hardware deposit forfeitures with certain suppliers.
(6)
Refer to the discussion of write-offs relating to parent company guarantee related arrangements in “— Impairment and Accounts Receivable Write-Off” in the notes to the consolidated financial statements in the Company’s Annual Report for the year ended December 31, 2025.
(7)
Impairment of inventory and other deferred costs represents charges to cost of goods to reduce the value of certain inventory items and deferred assets to their net realizable value.
(8)
Deposit forfeitures with certain hardware suppliers.
(9)
Impairment of DevCo project assets represent the excess of cost of goods over the sales transaction price for certain DevCo projects sold during the period.
(10)
Adjusted EBITDA for the quarter and year ended December 31, 2025 reflects other expenses of $6.0 million and $13.2 million, respectively. For the quarter ended December 31, 2025, other expenses includes $0.1 million for expenses related to restructuring costs to pursue greater efficiency and to realign our business and strategic priorities, and an accounts receivable write-off of $5.9 million. For the year ended December 31, 2025, other expenses includes $6.1 million for expenses related to restructuring costs to pursue greater efficiency and to realign our business and strategic priorities, an accounts receivable write-off of $5.9 million, $0.9 million for one-time costs associated with a loss on disposal and abandonment of property, plant and equipment, and $0.3 million of other non-recurring expenses. Adjusted EBITDA for the quarter and year ended December 31, 2024 reflects other expenses of $10.2 million and $14.3 million, respectively. For the quarter ended December 31, 2024, other expenses includes an accounts receivable write-off of $7.3 million, $2.6 million for expenses related to restructuring costs, and $0.3 million in connection with separation agreements for certain of the Company’s former executive officers. For the year ended December 31, 2024, other expenses includes an accounts receivable write-off of $7.3 million, $3.7 million for expenses related to restructuring costs, $1.2 million for advisory services relating to strategy, $1.5 million in connection with separation agreements for certain of the Company’s former executive officers, and $0.6 million of other non-recurring expenses.

Non-GAAP gross margin as used in the Company's full year 2026 guidance, is a non-GAAP financial measure that excludes or has otherwise been adjusted for items impacting comparability. The Company is unable to reconcile projected non-GAAP gross margin to GAAP gross margin, its most directly comparable forward-looking GAAP financial measure, without unreasonable efforts, because the Company is currently unable to predict with a reasonable degree of certainty its change in amortization of capitalized software, impairments, and other items that may affect GAAP gross margin. The unavailable information could have a significant effect on the Company’s full year 2026 GAAP financial results.

Stem’s PowerTrack™ EMS Selected for 100 MWh of Utility-Scale Energy Storage Projects in GermanyMarch 4, 2026 8:03 AM
Business Wire
PowerTrack Serves as the Integrated Control Foundation Enabling Market Participation at the Kölsa Site
Stem, Inc. (NYSE: STEM), a global leader in AI-enabled clean energy software and services, today announced that its PowerTrack™ Energy Management System (“EMS”) has been selected in collaboration with developer and EPC Everyray GmbH for two utility-scale battery energy storage system (“BESS”) projects in Germany: a 90 MWh installation in Kölsa and a 10 MWh installation in Elsterwerda. The projects are owned and financed by UESA Group, which is also supplying key electrical infrastructure, including the transformer station, handover station, and medium-voltage switchgear.
The Kölsa asset is co-located with an existing photovoltaic (“PV”) plant, while the Elsterwerda project is a standalone BESS installation. Together, the projects further expand Stem’s presence in the German market and reinforce PowerTrack EMS’s role as the control system for sophisticated, utility-scale storage deployments across Europe. Commercial operations are expected to commence in summer 2026.
“Our work with Everyray continues to demonstrate what’s possible when control infrastructure, optimization strategy, and engineering execution are aligned from the outset,” said Matt Tappin, President of Software at Stem. “As their portfolio grows in scale and sophistication, PowerTrack provides the operational backbone that enables consistent performance, regulatory compliance, and long-term asset value. We’re proud to support their continued expansion in the German market.”
PowerTrack EMS will serve as the primary control and management platform for the Kölsa BESS, leveraging Stem’s edge-to-cloud architecture to deliver continuous controller uptime, seamless integration, and robust grid code compliance. The system is certified under VDE-AR-N 4110, 4120, and 4130, covering the full range of medium and high voltage grid connection requirements applicable to utility-scale storage and hybrid assets in Germany. In addition to providing the core EMS platform, Stem is delivering engineering integration support to ensure seamless interoperability between the BESS, external optimization systems, and grid infrastructure.
“Delivering reliable, market-responsive storage requires tight coordination between hardware, control systems, and optimization platforms,” said Jochen Wolf, Co-Founder and Managing Director of Everyray GmbH. “Stem’s technical depth and collaborative integration approach have been instrumental in delivering a robust, grid-compliant solution.”
Everyray is deploying industry-leading solutions across the Kölsa site, including the optimization solution by Entrix, a market leader for trading flexible energy systems in Europe. The optimization solution will interface with PowerTrack EMS to execute AI-supported trading and ancillary services strategies. Stem’s vendor-neutral architecture enables asset owners to maintain flexibility in optimization strategy while ensuring secure, high-performance plant-level control.
“Battery storage plays an increasingly important role in strengthening the energy system by providing flexible capacity and reliable system support,” said Steffen Schülzchen, founder and CEO of Entrix. “Maximizing this value requires both technical excellence and sophisticated market execution. Through AI-powered optimization and 24/7 trading operations, we ensure that the Kölsa asset participates efficiently in Germany’s ancillary services and wholesale markets. Working alongside Everyray and Stem, we are combining advanced trading strategies with dependable, real-time plant control to deliver sustained performance and reliable market execution.”
The Kölsa and Elsterwerda deployments underscore Stem’s expanding role in Europe’s rapidly maturing storage market, where demand for scalable, vendor-neutral control architecture continues to grow alongside portfolio size and operational complexity.
