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, 2024.

John Carrington, Chief Executive Officer of Stem, commented, "The first quarter represented Stem's continuing efforts to maximize cash flow generation in 2024 through cost control and converting receivables to cash. We set a quarterly record for non-GAAP gross margin, and adjusted EBITDA improved year-over-year despite lower revenue in the quarter, highlighting our focus on operating efficiency and ongoing cost management. Our first quarter performance reflected breakeven operating cash flow given continued reductions in our working capital intensity. Importantly, we are accelerating the conversion of CARR-to-ARR with a +42% increase expected for 2Q24 through 4Q24 as a result of a company-wide focus on our 2024 guiding principles.

"Revenue in the first quarter was reduced by a $33 million non-cash adjustment as a result of an update of our estimates for variable consideration in connection with contract guarantees that we issued in 2022 and early 2023. Recent market dynamics, including the continued slowdown of interconnection timeframes and recent reductions in hardware prices, caused us to update our estimate of variable consideration for hardware related to these legacy contract guarantees. It's important to note that this adjustment had no impact on our cash flows in the quarter.

"During the quarter, we also canceled certain less profitable contracts in both our hardware and software backlog to focus on higher-margin opportunities. We believe that these decisions will set us up for improved profitability and cash generation in the future. We remain confident in our ability to generate more than $50 million of operating cash flow for full-year 2024.

"I am excited to announce our new PowerTrack^TM Asset Performance Management (APM) suite, a software solution that centralizes and streamlines the management of storage, solar, and hybrid energy asset portfolios. Built on the dual foundation of Stem's solar asset monitoring software and the Athena platform, PowerTrack APM revolutionizes how technical asset managers, commercial asset managers, and operations managers collaborate around a unified set of metrics and streamlined processes. PowerTrack APM was built by storage and solar industry experts to surface the right insights at the right time to reduce operational risk and maximize asset and portfolio performance.

"As we expected with our expansion into large-scale front-of-the-meter (FTM) storage projects, our bookings have become increasingly variable on a quarterly basis. We reiterate our full-year $1.5-$2.0 billion bookings target for 2024, based on contracts that are in advanced stages of negotiation or are expected to close in the near-term. We also expect meaningful year-over-year growth in software services revenue. We are maintaining our guidance for positive adjusted EBITDA and operating cash flow for full-year 2024. And we continue our focus on strengthening our balance sheet. I am confident that the actions we are taking to drive free cash flow place the Company on a solid foundation for growth, including an acceleration in our conversion of accounts receivable to cash as well as the strong backlog underlying our revenue and gross margin expectations for the balance of the year."

¹ The Company recorded a net revenue reduction of $33 million in hardware revenue during the three months ended March 31, 2024 due to recent market conditions. These conditions resulted in changes in initial estimates related to previously disclosed guarantees issued by the Company under certain customer contracts, most of which were entered into in 2022. See 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 such revenue reduction.

First Quarter 2024 Financial and Operating Results

Financial Results

Revenue decreased 62% year-over-year to $25.5 million, versus $67.4 million in the first quarter of 2023. The decrease was primarily driven by a $33 million reduction in revenue due to non-cash variable consideration adjustments, as described below.

GAAP gross (loss) profit was $(24.2) million, or (95)%, versus $1.0 million, or 1%, in the first quarter of 2023. The year-over-year decrease in GAAP gross profit was primarily driven by the $33 million reduction in revenue, partially offset by more favorable supply costs.

Non-GAAP gross profit was $13.8 million, or 24%, versus $15.1 million, or 19%, in the first quarter of 2023. The year-over-year decrease in non-GAAP gross profit was largely due to lower revenue, which was partially offset by a reduction in cost of hardware revenue and an increased mix of higher-margin solar products.

Net loss was $72.3 million versus first quarter 2023 net loss of $44.8 million, largely due to the $33 million reduction in revenue.

Adjusted EBITDA was $(12.2) million compared to $(13.7) million in the first quarter of 2023, with the slight improvement largely driven by gross margin improvement and continued cost control.

The Company ended the quarter with $112.8 million in cash and short-term investments, consisting of $112.8 million in cash and cash equivalents, as compared to $113.6 million in cash and short-term investments at the end of the fourth quarter 2023.

Operating Results

Contracted backlog was $1.6 billion at the end of the first quarter of 2024, compared to $1.9 billion as of the end of the fourth quarter of 2023, representing a 16% sequential decrease. The decrease in contracted backlog in the quarter was driven by a newly implemented, proactive effort to upgrade the profitability profile of the backlog, focusing resources on the most compelling opportunities. The result was a cancellation of approximately $257 million of lower-margin contracts.

Bookings were $23.8 million in the first quarter of 2024 versus $363.5 million in the first quarter of 2023. The decrease in bookings versus the prior year period was primarily associated with Stem's expansion into increasingly larger, utility-scale projects, which present variability in the cadence of quarterly bookings.

Contracted storage AUM increased 5% sequentially to 5.8 GWh for the first quarter of 2024, driven by new contract wins, partially offset by the previously described proactive contract cancellations. Solar monitoring AUM decreased 2% sequentially to 26.9 GW for the first quarter of 2024.

CARR decreased 2% to $89.3 million at the end of the first quarter of 2024 versus $91.0 million as of the end of the fourth quarter of 2023. The decrease in CARR was due to the previously described proactive backlog adjustment that resulted in cancelling $3.5 million of annualized service contracts.

The following table provides a summary of backlog at the end of the first quarter of 2024, compared to backlog at the end of the fourth quarter of 2023 ($ in millions):

End of 4Q23	$	1,929.3

Some Factors Affecting our Business and Operations

As previously disclosed, the Company entered into certain contractual guarantees 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. Due to recent market conditions, recorded a net revenue reduction of $33 million in hardware revenue during the three months ended March 31, 2024. The reduction in revenue was related to deliveries that occurred prior to the current fiscal year.

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 actively advancing projects under fixed price contracts that it expects will consume approximately 50% of the remaining hardware subject to guarantees, based on current market conditions. It is anticipated that these transactions will close in the second and third quarters of 2024, at which point they will not be subject to future adjustment. The Company believes that these transactions will enable it to convert accounts receivable into cash more quickly. The remaining hardware subject to guarantees are currently valued at approximately $50 million, after giving effect to the $33 million adjustment. The Company intends to integrate this hardware into development projects, which are expected to be available for sale late in the second half of 2024 and to be operational in the second half of 2025. The Company will continue to evaluate the economics of these transactions based on then-current conditions. Any remaining hardware that is not integrated into future projects remain subject to potential future updates to estimates of variable consideration, which may result in one or more future impairments.

Stem continues to diversify its supply chain, integrate additional energy technologies, and deploy a portion of its balance sheet to help position the Company to meet the expected significant growth in customer demand. We are 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 to 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 income (loss) attributable to Stem before depreciation and amortization, including amortization of internally developed software, net interest expense, further adjusted to exclude stock-based compensation and other income and expense items, including gain (loss) on the extinguishment of debt, revenue constraint, reduction in revenue, excess supplier costs, change in fair value of derivative liability, transaction and acquisition-related charges, litigation expense, restructuring costs, 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.

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, and impairment loss of project 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) Adjusted EBITDA for the three months ended March 31, 2024 reflects other expenses of $1.5 million. For the three months ended March 31, 2024, other expenses include $0.4 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.

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.
