Stem, Inc. ("Stem," "we" or the "Company") (NYSE:STEM), a global leader in artificial intelligence (AI)-driven clean energy solutions and services, announced today its financial results for the three months ended March 31, 2025.

"We made meaningful progress advancing our strategic priorities in the first quarter, especially in our software-related businesses," said Arun Narayanan, Chief Executive Officer of Stem. "Our renewed focus on PowerTrack is driving software revenue growth and we have taken decisive action to optimize our cost structure and enhance our software development capabilities. Our recently announced targeted workforce reductions are consistent with our software-focused strategy and are expected to generate approximately $30 million in annual cash cost savings, including $24 million expected to benefit this year. While these changes to our team are challenging in the short term, we believe our organizational restructuring will streamline operations and empower our team to drive profitable growth over the near and long term."

"The first quarter of 2025 showed strong execution of our strategic initiatives and demonstrates that we are steering Stem in the right long-term direction," said Doran Hole, Chief Financial Officer and Executive Vice President of Stem. "We achieved strong GAAP and non-GAAP gross margins, driven by the strength of our high-margin software, services, and edge device offerings. We achieved another positive milestone this quarter by generating positive cash flow from operations for the first time in our history, reflecting the strength of our business model and execution of our strategy. Given these results, we are reaffirming our full year 2025 guidance across all metrics."

First Quarter 2025 Financial and Operating Results

Financial Results

Revenue for the first quarter of 2025 increased 27% year-over-year to $32.5 million, versus $25.5 million in the first quarter of 2024. As previously disclosed, reported revenue for the first quarter of 2024 reflects a $33.1 million reduction in revenue due to updated valuations of certain contracts that provide parent company guarantees for hardware revenue recorded in 2022 and 2023.

GAAP gross profit (loss) was $10.5 million, or 32%, versus $(24.2) million, or (95)%, in the first quarter of 2024. The year-over-year increase in GAAP gross profit ($) and GAAP gross margin (%) was primarily driven by a higher mix of software and services revenue in the quarter, and the absence of the $33.1 million non-recurring item discussed above.

Non-GAAP gross profit was $14.8 million, or 46%, versus $13.8 million, or 24%, in the first quarter of 2024. The year-over-year increase in non-GAAP gross profit ($) and non-GAAP gross margin (%) was due to a higher contribution from software and services revenue in the quarter.

Net loss was $25.0 million versus first quarter 2024 net loss of $72.3 million. The year-over-year change was primarily due to higher gross profit and lower operating costs.

Adjusted EBITDA was $(4.6) million compared to $(12.2) million in the first quarter of 2024, primarily due to higher gross profit and lower operating costs.

The Company ended the first quarter of 2025 with $58.6 million in cash and cash equivalents, an increase of approximately $2.3 million versus $56.3 million in cash and cash equivalents reported at the end of the fourth quarter 2024.

Operating Results

The definitions of bookings, contracted backlog, and CARR have been revised versus prior periods.

Contracted backlog was $25.3 million at the end of the first quarter of 2025, compared to $20.9 million as of the end of the fourth quarter of 2024, representing a 21% sequential increase.

Bookings were $34.5 million in the first quarter of 2025 versus $37.6 million in the fourth quarter of 2024.

Storage operating AUM decreased 11% sequentially to 1.6 GWh for the first quarter of 2025 due to the removal of PowerBidder Pro contracts. Solar operating AUM increased 8% sequentially to 32.4 GW for the first quarter of 2025 driven by system activations.

CARR increased 7% sequentially to $69.0 million at the end of the first quarter of 2025 from $64.5 million at the end of the fourth quarter of 2024, driven by increased bookings.

ARR increased 8% sequentially to $56.9 million at the end of the first quarter of 2025 from $52.8 million at the end of the fourth quarter of 2024. This increase of $4.1 million was driven by system activations and higher renewals.

The following table provides a summary of backlog at the end of the first quarter of 2025, compared to backlog at the end of the fourth quarter of 2024 ($ in millions):

End of 4Q24	$	20.9
Add: Bookings		18.2
Less: Hardware revenue		(14.3	)
Project and professional services revenue		(1.7	)
Amendments/Cancellations		2.2
End of 1Q25	$	25.3

Outlook

The Company is reaffirming its full year 2025 guidance as follows ($ millions, unless otherwise noted):

		Previous
Revenue		$125 - $175
Software, edge hardware, & services		$120 - $140
Battery hardware resale		Up to $35

Non-GAAP Gross Margin (%)*		30% - 40%

Adjusted EBITDA		$(10) - $5

Operating Cash Flow		$0 - $15

Business Updates

On January 16, 2025, the Company's Board of Directors (the "Board") appointed Arun Narayanan as Chief Executive Officer, effective January 27, 2025. Effective as of that date, David Buzby stepped down as Interim CEO and Executive Chairman of the Board and re-assumed the role of Chairman of the Board. On March 18, 2025, the Board appointed software and finance veterans Vasudevan Guruswamy and Krishna Shivram to the Board.
In April 2025, the Company implemented an organizational realignment, including the establishment of distinct business units ("BU"), namely software, professional services, managed services and OEM hardware. Each BU has full profit and loss responsibility, which is expected to drive accountability, accelerate decision-making, unlock operational efficiencies, and optimize capital deployment across the Company.
On April 9, 2025, and as part of the organizational realignment, the Company announced a reduction of its global workforce of approximately 27%, as part of the Company's broader efforts to prioritize investments in software, reduce operating costs, increase efficiency, drive profitable growth and increase stockholder value. The Company estimates that it will incur charges of approximately $6.0 million to $6.5 million, primarily consisting of severance payments, notice period payments in applicable jurisdictions, employee benefits and related costs. The Company expects to incur these expenses primarily in the second quarter of 2025.
On April 23, 2025, the Company filed its definitive proxy statement for its 2025 Annual Meeting of Stockholders ("Annual Meeting"), which will occur on June 4, 2025. As part of the Annual Meeting, the Company is seeking stockholder approval of a reverse stock split at a ratio of 1-for-10 up to a ratio of 1-for-20. The reverse stock split is intended to enable the Company to regain compliance with the minimum listing standards of the New York Stock Exchange.

Some Factors Affecting our Business and Operations

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 provide 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 accounts for specified contractual guarantees as variable consideration. The Company reviews its estimate of variable consideration, including changes in estimates related to such guarantees, each quarter for facts or circumstances that have changed from the time of the initial estimate. As previously disclosed, the Company recorded a net revenue reduction of $33.1 million during the three months ended March 31, 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. The Company has not issued such guarantees since June 2023 and does not intend to issue any new guarantees in the future.

There are no remaining PCGs outstanding, and the Company expects no future impact on its financial results as a result of PCGs.

The Company is subject to risk and exposure from the evolving macroeconomic, geopolitical and business environment, including uncertainty regarding the U.S. government's potential changes to the Inflation Reduction Act, the effects of increased global inflationary pressures and interest rates, import tariffs and retaliatory trade policies, potential economic slowdowns or recessions, and geopolitical pressures, including the armed conflicts between Russia and Ukraine, and in the Gaza Strip and nearby areas, as well as tensions between China and the United States, and uncertainty around current and future trade policies. 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 reduction in revenue, excess supplier costs and resulting liquidated damages, 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, impairments related to decommissioning of end-of-life systems, excess supplier costs and resulting liquidated damages, and reduction in revenue. Non-GAAP gross margin is defined as non-GAAP gross profit (loss) as a percentage of revenue.

In the three months ended March 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. This in turn caused fulfillment and delivery delays on an order to one of our customers, as a result of which we further incurred liquidated damages of $4.8 million during the year ended December 31, 2023 under the customer contract. Because we had not previously incurred costs above initially agreed upon prices with a hardware supplier and were subsequently required to pay liquidated damages to a customer, we excluded these two items from adjusted EBITDA and non-GAAP gross profit to better facilitate comparisons of our underlying operating performance across periods.

As stated above, in certain customer contracts, the Company previously agreed to provide a guarantee that the value of purchased hardware will not decline for a certain period of time. The Company accounted for such contractual terms and guarantees as variable consideration at each measurement date. The Company reviewed its estimate of variable consideration each quarter, including changes in estimates related to such guarantees, for facts or circumstances that changed from the time of the initial estimate. Additionally, as a result of impairment of accounts receivables related to contracts that provided for a parent company guarantee, the Company recorded a bad debt expense of $104.1 million during the year ended December 31, 2024.

RECONCILIATIONS OF NON-GAAP FINANCIAL MEASURES
(UNAUDITED)

The following table provides a reconciliation of adjusted EBITDA to net loss:

	Three Months Ended March 31,
	2025			2024
	(in thousands)
Net loss	$	(25,000	)	$	(72,307	)
Adjusted to exclude the following:
Depreciation and amortization ⁽¹⁾		11,695			11,154
Interest expense		4,290			4,707
Stock-based compensation		4,317			8,374
Revenue reduction, net ⁽²⁾		—			33,128

Adjusted EBITDA	$	(4,627	)	$	(12,239	)

Adjusted EBITDA, as used in the Company's full year 2025 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, and other items that may affect net loss. The unavailable information could have a significant effect on the Company's full year 2025 GAAP financial results.

(1) Depreciation and amortization includes depreciation and amortization expense, impairment loss of energy storage systems, impairment loss of project assets, and impairment loss of right-of-use assets.

(2) Refer to the discussion of reduction in revenue in the definition of non-GAAP gross profit provided above.

(3) Refer to the discussion of excess supplier costs in the definition of non-GAAP gross profit provided above.

(4) Adjusted EBITDA for the three months ended March 31, 2024 reflects other expenses of $1.5 million, comprised of $1.1 million for expenses related to restructuring costs to pursue greater efficiency and to realign our business and strategic priorities, and $0.4 million of other non-recurring expenses.

The following table provides a reconciliation of non-GAAP gross profit and margin to GAAP gross profit (loss) and margin ($ in millions):

	Three Months Ended March 31,
	2025			2024
Revenue	$	32.5		$	25.5
Cost of revenue		(22.0	)		(49.7	)
GAAP gross profit (loss)		10.5			(24.2	)
GAAP gross margin (%)		32	%		(95	)%

Non-GAAP Gross Profit
GAAP Revenue	$	32.5		$	25.5
Add: Revenue reduction, net ⁽¹⁾		—			33.1
Subtotal		32.5			58.6
Less: Cost of revenue		(22.0	)		(49.7	)
Add: Amortization of capitalized software & developed technology		4.3			3.9
Add: Excess supplier costs⁽²⁾		—			1.0
Non-GAAP gross profit	$	14.8		$	13.8
Non-GAAP gross margin (%)		46	%		24	%

Non-GAAP gross margin as used in the Company's full year 2025 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 2025 GAAP financial results.

(1) Refer to the discussion of reduction in revenue in the definition of non-GAAP profit provided above.

(2) Refer to the discussion of excess supplier costs in the definition of non-GAAP profit provided above.
