Stem, Inc. ("Stem" or the "Company") (NYSE:STEM), a global leader in artificial intelligence (AI)-driven energy solutions and services, announced today its financial results for the three and 12 months ended December 31, 2022. Reported results reflect AlsoEnergy's operations from February 1, 2022 through December 31, 2022.

John Carrington, Chief Executive Officer of Stem, commented, "We executed well in 2022, with record performance across multiple metrics including revenue, storage AUM, contracted backlog, and CARR. We delivered these strong results while effectively managing several headwinds that faced the wider industry, including supply chain volatility, interconnection and permitting delays, cost inflation, and import restrictions, which is a testament to our exceptional employees.

"Our commercial success continued in the fourth quarter, including a record $458 million in new bookings, which exceeded our entire bookings for full year 2021, and a backlog of nearly $1 billion exiting the year. CARR grew 7% sequentially, to $65 million, and our services revenue grew 17% sequentially, reflecting our focus on and success in growing our long-term, high-margin software and services revenue. We are excited about our new partnerships, including a joint EV charging offering with ChargePoint, which we expect will benefit customers and drive higher growth and margins for the Company. Our fourth quarter results were in line with the interim update we provided in early January.

"We are introducing full-year 2023 financial and operating guidance, which reflects another year of strong forecasted growth across all of our key metrics. As previously discussed, we are actively driving towards achieving positive adjusted EBITDA, which we continue to expect to occur in the second half of 2023, marking an exciting milestone in the Company's trajectory and setting the foundation for increased profitability in the years to come."

Fourth Quarter and Full Year 2022 Financial and Operating Results

Financial Results

Fourth quarter 2022 revenue increased 194% to a record $156 million, versus $53 million in the fourth quarter of 2021. Full year 2022 revenue increased 186% to a record $363 million versus $127 million in full year 2021. Higher hardware revenue from Front-of-the-Meter (FTM) partnership agreements drove a majority of the increase for the quarter and the year, in addition to $18 million and $58 million of revenue contribution from AlsoEnergy for the quarter and year, respectively.

Fourth quarter 2022 GAAP Gross Margin was $13 million, or 8%, versus $(2) million, or (3)%, in the fourth quarter of 2021, and $9 million, or 9%, in the third quarter of 2022. Full year 2022 GAAP Gross Margin was $33 million, or 9%, versus full year 2021 GAAP Gross Margin of $1 million, or 1%. The year-over-year increase in GAAP Gross Margin for the fourth quarter and full year resulted primarily from higher hardware sales and additional higher-margin software and services revenues, including from AlsoEnergy.

Fourth quarter 2022 Non-GAAP Gross Margin was $17 million, or 11%, versus $3 million, or 5%, in the fourth quarter of 2021, and $12 million, or 13% in the third quarter of 2022. The year-over-year increase in Non-GAAP Gross Margin for the fourth quarter and full year resulted from higher volumes. In percentage terms, the year-over-year increase in Non-GAAP Gross Margin resulted from a higher mix of software and services, inclusive of AlsoEnergy, and higher hardware margins.

Fourth quarter 2022 Net Loss was $35 million versus fourth quarter 2021 Net Loss of $34 million. Full year 2022 Net Loss was $124 million versus full year 2021 Net Loss of $101 million. For the quarter and the year, the increase was primarily driven by higher personnel costs, including increases in stock-based compensation of $2.7 million and $15.1 million in fourth quarter and full year 2022, respectively.

Fourth quarter 2022 Adjusted EBITDA was $(10) million compared to $(12) million in the fourth quarter of 2021. Full year 2022 Adjusted EBITDA was $(46) million compared to $(30) million in full year 2021. For the year, lower Adjusted EBITDA was primarily driven by higher operating expenses resulting from increased personnel costs and continued investment in our growth initiatives.

The Company ended the fourth quarter of 2022 with $250 million in cash, cash equivalents, and short-term investments, consisting of $88 million in cash and cash equivalents and $162 million in short-term investments, as compared to $294 million in cash, cash equivalents, and short-term investments at the end of the third quarter 2022. The primary uses of cash during the fourth quarter of 2022 related to purchases of hardware for customer projects, which are expected to convert to revenue in coming quarters.

Operating Results

Contracted Backlog was $969 million at the end of the fourth quarter of 2022, compared to $817 million as of the end of the third quarter of 2022, representing a 19% sequential increase. The increase in Contracted Backlog in the fourth quarter of 2022 resulted from quarterly bookings of $458 million, partially offset by revenue recognition, a contract cancellation, and contract amendments. Bookings of $458 million in the fourth quarter of 2022 increased by 111% year-over-year versus $217 million in fourth quarter 2021. Full year 2022 bookings of $1.1 billion were more than two times higher than full year 2021 bookings of $417 million.

Fourth quarter 2022 contracted storage AUM increased 56% year-over-year and 4% sequentially to 2.5 GWh, driven by new contracts.

Fourth quarter 2022 CARR increased to $65 million, up from $61 million as of the end of the third quarter of 2022, an 7% sequential increase. The Company believes that CARR is an important operating metric because it provides visibility into the long-term growth in the Company's high-margin software revenue.

The Company's 12-month Pipeline was $7.1 billion at the end of the fourth quarter of 2022, compared to $7.2 billion at the end of the third quarter of 2022, representing a 1% sequential decrease. The Company will no longer report 12-month Pipeline beginning with the first quarter of 2023, as we believe that Contracted Backlog is a better indicator of near and medium term revenue given the more established nature of the Company's growth trajectory.

The following table provides a summary of backlog at the end of the fourth quarter of 2022, compared to backlog at the end of the third quarter of 2022 ($ millions):

End of 3Q22	$	817
Add: Bookings		458
Less: Hardware revenue		(139	)
Software/services		(15	)
Cancellations		(137	)
Amendments/other		(15	)
End of 4Q22	$	969

The Company continues to diversify its supply chain, adopt alternative technologies, and deploy a portion of its balance sheet to position the Company to meet the expected significant growth in customer demand. COVID-19 and its subvariants, potential import tariffs, and general economic, geopolitical, and business conditions, including the ongoing conflict between Russia and Ukraine and rising tensions between China and Taiwan, continue to affect and cause uncertainty in the supply chain and project timelines, and the Company has been affected by volatility in the costs of equipment and labor, and by rising interest rates. The Company continues to actively work to mitigate these effects on its financial and operational results, although there is no guarantee of the extent to which the Company will be successful in these efforts.

Recent Business Highlights

On January 31, 2023, the Company announced a joint eMobility offering with ChargePoint Holdings, Inc., a leading electric vehicle (EV) charging network. The joint offering is expected to help generate economic, environmental, and resilience benefits for owners, developers, and operators of EV charging stations. The offering will integrate Athena®, Stem's clean energy platform, on-site energy storage, and ChargePoint's Express Platform to help drive cost savings and maximize value now and over the lifetime of the assets.

On December 8, 2022, the Company announced four 9.9 megawatt standalone battery energy storage projects in Texas with REX Storage Holdings, LLC (REX), an independent power producer focused on Electric Reliability Council of Texas (ERCOT) power customers. REX is a joint venture between Regis Energy Partners LP, an independent developer, owner, and operator of energy storage systems, and Excelsior Energy Capital (EEC), a leading investment fund focused on renewable power generation. The projects represent the first of a $400 million equity commitment by REX to acquire additional projects from Regis' development pipeline in ERCOT.

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 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. 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 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 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 transaction and acquisition-related charges, the change in fair value of warrants and embedded derivatives, vesting of warrants, loss on extinguishment of debt, litigation settlement, 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 margin as gross margin excluding amortization of capitalized software and impairments related to decommissioning of end-of-life systems.

See the section below entitled "Reconciliations of Non-GAAP Financial Measures."

Adjusted EBITDA, as used in connection with the Company's full year 2023 guidance, is a non-GAAP financial measure that excludes or has otherwise been adjusted for items impacting comparability. The Company is unable to provide a reconciliation of forecasted 2023 Adjusted EBITDA to net loss, 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 stock-based compensation expense and other items that may affect net loss. The unavailable information could have a significant effect on the Company's full year 2023 GAAP financial results.

The following table provides a reconciliation of non-GAAP Gross Margin to GAAP Gross Margin ($ in millions, except for percentages):

	Three Months Ended December 31,						Twelve Months Ended December 31,
	2022			2021			2022			2021
Revenue	$	155.5		$	52.8		$	363.0		$	127.4
Cost of revenue		(142.9	)		(54.4	)		(329.9	)		(126.1	)
GAAP Gross Margin		12.6			(1.6	)		33.1			1.3
GAAP Gross Margin (%)		8	%		(3	)%		9	%		1	%

Adjustments to Gross Margin (1):
Amortization of capitalized software & developed technology		3.1			1.5			10.7			5.3
Impairments		1.3			2.7			3.5			4.6
Non-GAAP Gross Margin	$	17.0		$	2.6		$	47.3		$	11.2
Non-GAAP Gross Margin (%)		11	%		5	%		13	%		9	%

(1) Historically, the Company included a separate "Other Adjustments" caption in the table above as part of the adjustments to Gross Margin. Other Adjustments consisted of certain operating expenses including communication and cloud service expenditures reclassified to cost of revenue. Other Adjustments are no longer in the calculation of Non-GAAP Gross Margin and Non-GAAP Gross Margin %. The Company believes that this change reflects a more accurate representation of our business for stakeholders to assess its performance.

Non-GAAP Gross Margin as used in connection with the Company's full year 2023 guidance, is a non-GAAP financial measure that excludes or has otherwise been adjusted for items impacting comparability. The Company is unable to provide a reconciliation of forecasted 2023 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 2023 GAAP financial results.

Key Definitions:

Item		Definition
12-Month Pipeline		Total value (excluding market participation revenue) of uncontracted, potential hardware and software contracts that are currently being pursued by our direct salesforce and channel partners with developers and independent power producers seeking energy optimization services and transfer of energy storage systems, and which have a reasonable likelihood of contract execution within 12 months of the end of the relevant period. Pipeline is based on project timelines published by such developers and independent power producers. We cannot guarantee that our pipeline will result in meaningful revenue or profitability.
Bookings		Total value of executed customer agreements, as of the end of the relevant period (e.g. quarterly bookings or annual bookings) Customer contracts are typically executed 6-18 months ahead of installation The Booking amount typically includes: Hardware revenue, which is typically recognized at delivery of system to customer, Software revenue, which represents total nominal software contract value recognized ratably over the contract period, Market participation revenue is excluded from booking value
Contracted Backlog		Total value of bookings in dollars, as of a specific date Backlog increases as new contracts are executed (bookings) Backlog decreases as integrated storage systems are delivered and recognized as revenue
Contracted Storage AUM		Total GWh of systems in operation or under contract
Solar Monitoring AUM		Total GW of systems in operation or under contract
Contracted Annual Recurring Revenue (CARR)		Annual run rate for all executed software services contracts including contracts signed in the period for systems that are not yet commissioned or operating. The Company believes that CARR is a valuable metric because it provides visibility into the expected long-term growth in the Company's high-margin software revenue.
