Revising Full Year 2024 Guidance for Several Key Metrics

Third Quarter 2024 Financial and Operating Highlights

Financial Highlights

•Revenue of $29.3 million, down from $133.7 million in 3Q23. Reflects $5.6 million and $37.4 million reductions in revenue, respectively, due to revised negotiated valuations of assets under certain hardware price guarantees entered into in 2022 and 2023. Lower revenue in the quarter also reflects reduced battery hardware sales, partially offset by growth in software and services revenue1

•GAAP gross profit of $6.2 million, up from $(20.3) millionin 3Q23

•Non-GAAP gross profit of $16.2 million, down from $21.4 million in 3Q23, reflecting lower battery hardware revenue

•GAAP gross margin of 21%, up from (15)% in 3Q23

•Non-GAAP gross margin of 46%, up from 12% in 3Q23, reflecting a higher percentage of software and services revenue

•Net loss of $148.3 million versus net loss of $77.1 million in 3Q23, which includes $104.1 million of bad debt expense associated with impairment of accounts receivable related to customer contracts that provide a parent company guarantee1

•Adjusted EBITDA of $(3.5) million versus $(0.9) million in 3Q23

•Operating cash flow of $(9.4) million versus $(4.0) million in 3Q23

•Ended 3Q24 with $75.4 million in cash and cash equivalents, versus $89.6 million at the end of2Q24

Operating Highlights

•Bookings of $29.1 million, versus $676.4 million in 3Q23, driven primarily by lower battery hardware resale bookings

•Contracted backlog of $1.5 billion, down 17% from the end of 3Q23, and down 2% from the end of 2Q24

•Contracted storage assets under management (“AUM”) of 6.0 gigawatt hours (“GWh”), up 20% from the end of 3Q23 and up 3% from the end of 2Q24

•Solar monitoring AUM of 28.5 gigawatts (“GW”), up 8% from the end of 3Q23 and up 6% from the end of 2Q24

SAN FRANCISCO – October 30, 2024 – 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 and nine months ended September 30, 2024.

“We reported another strong quarter of growth in Annual Recurring Revenue, driven by continued adoption of our industry-leading software,” said David Buzby, Interim Chief Executive Officer of Stem. “Revenue was down significantly due to lower hardware revenue in the quarter. We have begun to implement our new strategy that we announced in early October, which we expect to drive more predictable, scalable growth in software and services revenue and improved profitability in the long-term.”

“Sequential growth in software and services revenue drove strong GAAP gross margins of 21%, and record non-GAAP gross margins of 46% in the third quarter,” said Doran Hole, Chief Financial Officer and Executive Vice President. “Revenue was negatively impacted by a $5.6 million adjustment tied to an updated valuation of certain hardware contract guarantees that we issued in 2022 and early 2023. Our bad debt expense increased sequentially by $104.1 million in the quarter, due to an impairment of accounts receivables related to certain customer contracts

1See the section below entitled “Some Factors Affecting our Business and Operations.” Adjusted EBITDA and non-GAAP gross profit and margin percentage for the quarter have been adjusted to exclude the impact of the $5.6 million revenue reduction. In addition, adjusted EBITDA for the quarter has been adjusted to exclude the impact of the $104.1 million of bad debt expense. Further details are provided below in the section entitled “Definitions of Non-GAAP Financial Measures.”

that provide a parent company guarantee. As a result, our net income was negatively impacted by $104.1 million. With the adjustments made this quarter, we have reduced the value of all relevant assets subject to parent company guarantees to zero on our balance sheet, and do not expect further material negative impact on our financial statements as a result of these guarantees.”

“We are adjusting our full year 2024 guidance for several key metrics to account for our latest financial results, ongoing implementation of our new strategy and continued expectation of project delays, which continue to negatively impact our results including revenue, bookings and cash flow,” said Mr. Hole. “We are also taking actions to right-size our operating costs to conserve cash and align with our new strategy. We are confident that the changes we are making will position the Company to drive faster, more predictable growth in high-margin revenue streams, and improved profitability in the long-term.”

Third Quarter 2024 Financial and Operating Results

Financial Results

Revenue decreased 78% year-over-year to $29.3 million, versus $133.7 million in the third quarter of 2023. Reported revenue reflects a $5.6 million reduction in the quarter, and a $37.4 million reduction in the third quarter of 2023, in both cases due to updated valuations of certain contract guarantees for hardware revenue recorded in 2022 and 2023. The lower year-over-year revenue reflects significantly reduced battery hardware sales, partially offset by strong growth in software and services revenue.

GAAP gross profit (loss) was $6.2 million, or 21%, versus $(20.3) million, or (15)%, in the third quarter of 2023. The year-over-year increase in GAAP gross profit ($) and GAAP gross margin (%) was primarily driven by a higher mix of software and services revenue in the quarter, and a smaller reduction related to certain contract guarantees ($5.6

2

million) in the quarter, versus a similar revenue reduction in third quarter 2023 ($37.4 million).

Non-GAAP gross profit was $16.2 million, or 46%, versus $21.4 million, or 12%, in the third quarter of 2023. The year-over-year decrease in non-GAAP gross profit ($) was largely due to lower storage hardware revenue.The year-over-year increase in Non-GAAP gross margin (%) was primarily driven by a much higher contribution from high margin software and services revenue in the quarter.

Net loss was $148.3 million versus third quarter 2023 net loss of $77.1 million. The year-over-year change was primarily driven by $104.1 million of bad debt expense associated with impairment of receivables related to customer contracts that provide a parent company guarantee, as well as lower revenues in the quarter.

Adjusted EBITDA was $(3.5) million compared to $(0.9) million in the third quarter of 2023, primarily due to lower gross profit, partially offset by lower operating costs.

The Company ended the third quarter of 2024 with $75.4 million in cash and cash equivalents, as compared to $89.6 million in cash and cash equivalents at the end of the second quarter 2024.

Operating Results

Contracted backlog was $1.55 billion at the end of the third quarter of 2024, compared to $1.58 billion as of the end of the second quarter of 2024, representing a 2% sequential decrease. The slight decrease in contracted backlog in the quarter was driven by the conversion of backlog to revenue and low bookings in the quarter.

Bookings were $29.1 million in the third quarter of 2024 versus $676.4 million in the third quarter of 2023. Bookings remain highly variable due to the Company’s previous expansion into large front-of-the-meter (FTM) storage projects and the recent strategic shift towards higher-margin software and services versus hardware sales.

Contracted storage AUM increased 3% sequentially to 6.0 GWh for the third quarter of 2024. Solar monitoring AUM increased 6% sequentially to 28.5 GW for the third quarter of 2024.

CARR increased 2% to $92.3 million at the end of the third quarter of 2024 versus $90.1 million at the end of the second quarter of 2024.

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

End of 2Q24	$	1,578.5
Add: Bookings	29.1
Less: Hardware revenue	(13.8)
Software/services activations	(43.2)

End of 3Q24	$	1,547.4

Strategy Review Outcome

On October 1, 2024, the Company announced the outcome of its previously announced review of its corporate strategy. The Company expects its new strategic priorities will drive more predictable recurring revenue at significantly higher gross margins than the Company has previously realized and will enable more scalable growth. The new strategy is driven by four key strategic priorities: (1) shift to software and services-centric business to drive predictable, recurring, high-margin revenue, (2) expand and emphasize energy services as a competitive differentiator and enable more predictable revenue, (3) deliver enhanced AI-enabled software and edge device capabilities, and (4) provide hardware procurement advisory services, rather than procure hardware as the primary go-to-market approach. The Company will continue to provide hardware procurement, but only under certain strict profitability and working capital guidelines.

Recent Business Updates

On September 16, 2024, the Company announced that John Carrington stepped down as Chief Executive Officer and as a member of the Board of Directors of the Company (the “Board”), effective immediately. The Board has engaged an executive search firm to conduct a search, which includes internal and external candidates, for a permanent CEO. David Buzby, Executive Chair of the Board, was appointed interim CEO. Mr. Buzby will continue to serve as Executive Chair of the Board.

On October 23, 2024, the Company announced the appointment of Albert Hofeldt, PhD as Stem’s Chief Technology Officer (CTO), effective immediately. Dr. Hofeldt will lead Stem’s efforts to deliver enhanced AI-enabled software and edge device capabilities as part of the company’s recently announced software and services-centric strategy.

Outlook

The Company is updating its full year 2024 guidance ranges to account for the Company’s recent financial results, ongoing implementation of its new strategy and continued expectation of project delays, which continue to negatively impact results, as follows ($ millions, unless otherwise noted):

	Previous	Updated
Revenue	$200 - $270	$135 - $155
Non-GAAP Gross Margin (%)	25% - 30%	32% - 36%

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 $37.4 million in hardware revenue during the three months ended September 30, 2023, a net revenue reduction of $38.7 million during the three months ended March 31, 2024 due to market conditions, and a net revenue reduction of $5.6 million during the three months ended September 30, 2024 due to revised negotiated valuations of assets under certain hardware price guarantees entered into in 2022 and 2023. Such reductions in revenue are related to deliveries that occurred prior to 2023. Additionally, the Company recorded a $104.1 million bad debt expense during the three months ended September 30, 2024, as a result of an impairment of accounts receivable related to customer contracts that provide a parent company guarantee. The Company has not issued such guarantees since June 2023, and does not intend to issue any new guarantees in the future.

The Company is subject to risk and exposure from the evolving macroeconomic, geopolitical and business environment, including the effects of increased global inflationary pressures and interest rates, potential import tariffs, 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 unknown effects of current and future trade and other regulations. We regularly monitor 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 revenue constraint, reduction in revenue, excess supplier costs, change in fair value of derivative liability, impairment of goodwill, contract termination payment,

5

restructuring costs, impairment of accounts receivable related to customer contracts that provide parent company guarantees, 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 may 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, reduction in revenue, and including revenue constraint. Non-GAAP gross margin is defined as non-GAAP gross profit as a percentage of revenue.

The Company generally records the full purchase order value as revenue at the time of hardware delivery; however, for certain non-cancelable purchase orders entered into during the first quarter of 2023, the final settlement amount payable to the Company is variable and indexed to the price per ton of lithium carbonate in the first quarter of 2024 such that the Company may increase or decrease the final prices in such purchase orders based on the price per ton of lithium carbonate at final settlement. Lithium carbonate is a key raw material used in the production of hardware systems that the Company ultimately sells to customers. The total dollar amount of such purchase orders for the indexed contracts is approximately $52 million. However, as a result of the pricing structure in such purchase orders, the Company recorded revenue in the first quarter of 2023 of approximately $42 million in accordance with GAAP, net of a $10 million revenue constraint, using a third party forecast of the lithium carbonate trading value in the first quarter of 2024. Because the Company had not before used indexed pricing in its customer contracts or purchase orders and had not previously constrained revenue related to forecasted inputs of its hardware systems, the Company believes that including the $10.2 million revenue constraint from the first quarter of 2023 into non-GAAP gross profit enhances the comparability to the Company’s non-GAAP gross profit in prior periods. The Company expects to receive, pursuant to such purchase orders, final consideration of at least $34 million.The Company recorded the full cost of hardware revenue for these indexed contracts in the first quarter of 2023.

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 accounts for such contractual terms and guarantees as variable consideration at each measurement date. The Company reviews its estimate of variable consideration each quarter, including changes in estimates related to such guarantees, for facts or circumstances that have 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. See the section below entitled “Reconciliations of Non-GAAP Financial Measures.”

Adjusted EBITDA, as used in the Company's full year 2024 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 2024 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 revenue constraint in the definition of non-GAAP gross profit provided above.

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

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

(5) Contract termination payment to a vendor for the delivery of hardware.

(6) See Note 3 – “Impairment and Accounts Receivable Write-Off” in the notes to the unaudited condensed consolidated financial statements in the Company’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2024.

(7) Adjusted EBITDA for the three and nine months ended September 30, 2024 reflects other expenses of $2.5 million and $4.1 million, respectively. For the three months ended September 30, 2024, other expenses includes $1.2 million for advisory services relating to strategy and $1.3 million in connection with separation agreements for certain of the Company’s former executive officers. For the nine months ended September 30, 2024, other expenses are comprised of $1.2 million for advisory services relating to strategy, $1.3 million in connection with separation agreements for certain of the Company’s former executive officers, $0.5 million of other non-recurring expenses, and $1.1 million of expenses related to restructuring costs to pursue greater efficiency and to realign our business and strategic priorities. Restructuring expenses consisted of employee severance and other exit costs.

Non-GAAP gross profit	$	16.2		$	21.4		$	43.5		$	52.9
Non-GAAP gross margin (%)	46		%	12		%	34		%	15		%

Non-GAAP gross margin as used in the Company's full year 2024 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 2024 GAAP financial results.

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

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