Second Quarter 2026 Financial and Operating Results

Financial Results

Revenue decreased 12% year-over-year to $33.7 million, versus $38.4 million in the second quarter of 2025, driven by significantly reduced battery hardware resales and lower managed services revenue. Revenue from software, services, and edge hardware was $33.4 million for the second quarter of 2026, up 1% from $32.9 million for the second quarter of 2025, driven by 11% year-over-year growth in PowerTrack software revenue, partially offset by lower managed services revenue.

GAAP gross profit was $13.9 million, or 41%, versus $12.8 million, or 33%, in the second quarter of 2025. The year-over-year increase in GAAP gross profit ($) and GAAP gross margin (%) was driven by reduced costs, increased higher-margin software, services, and edge hardware sales, and reduced lower-margin battery hardware resale and managed services revenue.

Non-GAAP gross profit was $18.4 million, or 55%, versus $18.7 million, or 49%, in the second quarter of 2025. The year-over-year decrease in non-GAAP gross profit ($) was driven by significantly decreased lower-margin battery hardware resales and managed services revenue. The year-over-year increase in non-GAAP gross margin (%) reflects increased higher-margin software, services, and edge hardware sales, along with reduced lower-margin battery hardware resale revenue.

Net loss was $14.4 million versus the second quarter of 2025 net income of $202.5 million. The year-over-year decrease was primarily due to a one-time gain on extinguishment of debt in the second quarter of 2025, which was partially offset by increased GAAP gross profit and lower operating expenses in the second quarter of 2026.

Adjusted EBITDA was $6.2 million, up 63% compared to $3.8 million in the second quarter of 2025. The year-over-year improvement was primarily driven by a higher mix of high-margin software and services revenue combined with lower operating expenses.

The Company ended the second quarter with $38.4 million in cash and cash equivalents, versus $36.6 million reported at the end of the first quarter of 2026.

Operating Results

Bookings were $36.8 million in the second quarter of 2026, up 39% from $26.5 million in the first quarter of 2026.

Contracted backlog was $27.1 million at the end of the second quarter of 2026, up 18% from $23.0 million at the end of the first quarter of 2026.

CARR was $69.0 million at the end of the second quarter of 2026, up 3% from $67.2 million at the end of the first quarter of 2026.

ARR increased 2% to $62.4 million at the end of the second quarter of 2026 from $61.2 million at the end of the first quarter of 2026. PowerTrack ARR increased 3% sequentially to $42.8 million in the second quarter of 2026 from $41.7 million at the end of the first quarter of 2026. Managed services ARR increased slightly to $19.6 million from $19.5 million at the end of the first quarter of 2026.

Solar operating AUM increased 2% sequentially to 38.3 GW for the second quarter of 2026. Storage operating AUM increased 6% sequentially to 1.8 GWh for the quarter.

The following table provides a summary of contracted backlog at the end of the second quarter of 2026, and includes only hardware and non-recurring services contracts, compared to backlog at the end of the first quarter of 2026 ($ in millions):

Business Updates

• On August 12, 2026, the Company announced that Solarmarkt Group, together with engineering, procurement, and construction partner Pannonwatt Energetikai Megoldások Zrt., selected Stem’s PowerTrack™ EMS as the integrated energy management, power plant control (PPC), and SCADA platform for the hybridization of two operating utility-scale solar plants in Hungary. The projects are expected to add a 40 MW / 80 MWh battery energy storage system to each of Solarmarkt Group’s existing 60 MWp solar facilities. Stem previously supplied the PPC capabilities for the solar assets in 2025 and 2026 using a hybrid-ready PowerTrack architecture. Under the new agreement, the same software and controls foundation are expected to expand across the battery systems at each site, helping to enable solar generation, storage, grid interconnection, and market dispatch to operate through a single integrated solution.

• On July 1, 2026, the Company announced that its PowerTrack EMS won The smarter E AWARD 2026 in the Smart Integrated Energy category. Organized by Solar Promotion International GmbH and Freiburg Management and Marketing International GmbH, The smarter E AWARD is presented across five industry categories, honoring pioneers of the energy industry driving major innovations across energy storage and smart integrated energy.

The award was announced during The smarter E Europe in Munich, Europe’s largest alliance of exhibitions for the energy industry, bringing together Intersolar Europe, ees Europe, Power2Drive Europe, and EM-Power Europe.

• On June 17, 2026, the Company announced the launch of AIONA, Stem’s AI services offering developed in direct response to growing customer and market demand for practical, execution-focused artificial intelligence solutions. AIONA builds on Stem’s deep experience applying AI, data science, optimization, and automation across complex clean energy environments.

• On May 27, 2026, the Company announced that Copec Flux, the renewable energy subsidiary of Copec S.A., is deploying Stem’s PowerTrack EMS at the Granja Solar project in Chile. This development expands Stem’s Latin America footprint and represents a meaningful step into the region’s utility-scale hybrid market. The Granja project is an existing 135 MW PV project that Copec is retrofitting with a 420 MWh BESS to create a hybrid solar-plus-storage facility that allows Copec to supply energy to the national energy grid at more valuable times. As part of that expansion, Stem’s PowerTrack EMS is expected to serve as the site’s master control system, providing the controls architecture needed to manage the integrated asset.

• On May 13, 2026, the Company announced that it entered into a services agreement with Bluesphere Ventures to support its portfolio of standalone battery energy storage projects participating in New York’s Value of Distributed Energy Resources (VDER) program. Under the agreement, Stem is expected to provide revenue modeling, market analysis, and intelligence across Bluesphere Ventures’ pipeline of battery storage projects located within Consolidated Edison (ConEd) territory in New York City.

• On April 30, 2026, the Company 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 BESS control stack. The agreement brings together Stem’s PowerTrack EMS and Unit Controller with Nuvation’s Battery Management System, to create an integrated control layer designed to meet growing demand for secure, compliant, and domestically sourced energy infrastructure.

• On April 28, 2026, the Company announced it acquired the assets of raicoon GmbH, a Vienna-based provider of automated fault detection and event management for solar asset performance. The acquisition enhances Stem’s PowerTrack platform by improving how operational data is analyzed and translated into action, helping customers identify, prioritize, and resolve performance issues more quickly across their renewable energy portfolios.

* See the section below titled “Reconciliations of Non-GAAP Financial Measures” for information regarding why Stem is unable to reconcile non-GAAP Gross Margin and adjusted EBITDA guidance to their most comparable financial measures calculated in accordance with GAAP.

** 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 the armed conflicts between Russia and Ukraine and in 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) income 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 change in fair value of warrant liability, impairment of assets held for sale, 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 as gross profit excluding amortization of capitalized software, and impairments related to decommissioning of end-of-life systems. We define non-GAAP gross margin as non-GAAP gross profit as a percentage of revenue.

Adjusted EBITDA		$	6,226			$	3,817			$	8,226			$	(810	)

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 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, 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 reflects depreciation and amortization expense, impairment loss of energy storage systems, and impairment loss of project assets.
(2)		As previously disclosed, the Company wrote off certain receivables determined to be uncollectible. During the three and six months ended June 30, 2025, the Company recovered $3.5 million of the receivables previously written off.
(3)		Adjusted EBITDA for the three and six months ended June 30, 2026 included other expenses of $1.2 million and $1.2 million, respectively. For the three months ended June 30, 2026, other expenses includes $1.1 million for acquisition and divestiture related charges and $0.1 million of other non-recurring expenses. For the six months ended June 30, 2026, other expenses includes $1.1 million for acquisition and divestiture related charges and $0.1 million of other non-recurring expenses.
Adjusted EBITDA for the three and six months ended June 30, 2025 included other expenses of $6.0 million and $6.0 million, respectively. For the three months ended June 30, 2025, other expenses includes $5.9 million for expenses related to restructuring costs to pursue greater efficiency and to realign our business and strategic priorities. For the six months ended June 30, 2025, other expenses includes $5.9 million for expenses related to restructuring costs to pursue greater efficiency and to realign our business and strategic priorities and $0.1 million of other non-recurring expenses.

The following table provides a reconciliation of non-GAAP gross profit and margin to GAAP gross profit and margin ($ in millions):
		Three Months Ended June 30,								Six Months Ended June 30,
			2026				2025				2026				2025
Revenue		$	33.7			$	38.4			$	62.7			$	70.9
Cost of revenue			(19.8	)			(25.6	)			(37.9	)			(47.6	)
GAAP gross profit			13.9				12.8				24.8				23.3
GAAP gross margin (%)			41	%			33	%			40	%			33	%
Adjustments to Gross Margin:
Amortization of capitalized software & developed technology			4.4				4.5				8.7				8.8
Impairments			0.1				1.4				0.1				1.4
Non-GAAP gross profit		$	18.4			$	18.7			$	33.6			$	33.5
Non-GAAP gross margin (%)			55	%			49	%			54	%			47	%

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.
