About this update from Stem, Inc.

Achieved fifth consecutive quarter of positive adjusted EBITDA PowerTrack TM software revenue up 11% YoY PowerTrack TM Energy Management System (EMS) recognized as leading, global innovative solution with The smarter E AWARD win Reaffirming full year 2026 financial and operating guidance HOUSTON, August 12, 2026 --( BUSINESS WIRE )--Stem, Inc. ("Stem," "we" or the "Company") (NYSE: STEM), a global leader in AI-enabled clean energy software and services, today announced its results for the quarter ended June 30, 2026. Financial Highlights Operating Highlights "The second quarter reflected strong momentum across our core PowerTrack platform and continued expansion of our international footprint," stated Arun Narayanan, Chief Executive Officer of Stem. "We brought PowerTrack EMS to Latin America this quarter with the Granja Solar project in Chile, where our software will serve as the control system for a 135 MW solar facility being retrofitted with a 420 megawatt-hour battery storage system – a strong proof point for the kind of hybrid, utility-scale project that validates the commercial prospects of our EMS offering. Our products were also recognized internationally, with PowerTrack EMS receiving 'The smarter E AWARD 2026' in Europe for the Smart Integrated Energy category, an honor given to industry pioneers driving major innovations across energy storage and smart integrated energy, and a prestigious recognition for the clean energy industry. Alongside this sustained commercial progress, we are continuing to execute with discipline, delivering our fifth consecutive quarter of positive adjusted EBITDA and record non-GAAP gross margins. We remain focused on driving operating leverage, strengthening our core platform, and building the foundation for accelerated growth in 2027 and beyond." "Our second quarter results reflect our continued dedication to driving operating leverage in the business," stated Brian Musfeldt, Chief Financial Officer of Stem. "Non-GAAP gross margins, adjusted EBITDA, and operating cash flow improved significantly versus the prior year. Because of our consistent performance and expectations for the rest of the year, we are pleased to reaffirm full year 2026 guidance across all metrics." 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 Outlook The Company is reaffirming its full-year 2026 guidance as follows ($ millions, unless otherwise noted ): 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. See also the section below entitled "Reconciliations of Non-GAAP Financial Measures."
