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 months ended September 30, 2022. Reported results in this press release reflect AlsoEnergy's operations from February 1, 2022 through September 30, 2022.

John Carrington, Chief Executive Officer of Stem, commented, "We continued to execute well in the third quarter, with record performance across multiple metrics, including revenue, storage AUM, pipeline, and contracted backlog. Revenue was above the top end of our guidance range for the third straight quarter, and margins were in-line with our expectations.

Our contracted backlog more than doubled as compared to the same quarter last year, driven by $223 million in bookings, which also more than doubled versus the third quarter of 2021. CARR grew 5% sequentially, to $61 million, reflecting our focus on growing our long-term, high-margin software, and services revenue. We are proud that Stem has been ranked #1 for innovation by Frost & Sullivan in its Optimization and Trading report, another independent testimony to our technology leadership.

We applaud the passage of the Inflation Reduction Act of 2022 in August. We expect that the climate provisions in the Act will drive continued investment in America's aging power grid, support further customer adoption of renewable energy, create additional clean energy jobs, and improve energy security by incentivizing the ongoing development of our domestic supply chain. We have started to see an increase in demand from our customers following the passage of the Act, as evidenced by the 29% sequential increase in our 12-month pipeline. In particular, many of our Behind-the-Meter (BTM) customers are increasing their investments in renewables as a result of the Act.

We are reaffirming our full-year 2022 guidance across all of our key metrics, and raising the bottom end of our guidance for bookings. We currently expect our Non-GAAP Gross Margin to trend towards the lower end of our guidance range due to continued supply chain constraints, primarily impacting AlsoEnergy due to delays in solar equipment deliveries. However, we continue to actively manage costs, and therefore expect adjusted EBITDA to trend towards the midpoint of our guidance. As previously discussed, we are actively driving towards achieving positive adjusted EBITDA, which we expect to occur in the second half of 2023, and increasing our profitability in the years to come."

Third Quarter 2022 Financial and Operating Results

Financial Results

Third quarter 2022 revenue increased 150% to $100 million, versus $40 million in the third quarter of 2021. Higher hardware revenue from Front-of-the-Meter (FTM) and BTM partnership agreements drove a majority of the year-over-year increase, in addition to $17 million of revenue contribution from AlsoEnergy.

Third quarter 2022 GAAP Gross Margin was $9 million, or 9%, versus $3 million, or 8%, in the third quarter of 2021. The year-over-year increase in GAAP Gross Margin resulted primarily from higher hardware sales and additional higher-margin software and services revenues, including from AlsoEnergy.

Third quarter 2022 Non-GAAP Gross Margin was $12 million, or 13%, versus $5 million, or 13%, in the third quarter of 2021. The year-over-year increase in Non-GAAP Gross Profit resulted from higher volumes. In percentage terms, Non-GAAP Gross Margin was flat, with additional software and services, inclusive of AlsoEnergy, offset by lower margins associated with the sale of FTM hardware.

Third quarter 2022 Net Loss attributable to Stem was $34 million versus third quarter 2021 Net Income of $116 million. The year-over-year decrease was primarily driven by non-cash revaluation of warrants tied to changes in the value of the underlying common stock reported in the third quarter of 2021. In June and September 2021, Stem redeemed all outstanding private and public warrants, respectively, which generally has resulted in a more streamlined capital structure and less quarter-to-quarter variability in the Company's Net Income (Loss).

Third quarter 2022 Adjusted EBITDA was $(13) million compared to $(7) million in the third quarter of 2021. 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 third quarter of 2022 with $294 million in cash, cash equivalents, and short-term investments, consisting of $100 million in cash and cash equivalents and $194 million in short-term investments, as compared to $335 million in cash, cash equivalents, and short-term investments at the end of the second quarter 2022. The primary uses of cash relate to purchases of hardware for customer projects that are expected to convert to revenue in coming quarters.

Operating Results

The Company's 12-month Pipeline was $7.2 billion at the end of the third quarter of 2022, compared to $5.6 billion at the end of the second quarter of 2022, representing 29% sequential growth. The increase in the 12-month pipeline was driven by increased FTM and BTM project opportunities, including significant expansions into new markets and continued growth in Stem's partner channels.

Contracted Backlog was $817 million at the end of the third quarter of 2022, compared to $727 million as of the end of the second quarter of 2022, representing a 12% sequential increase. The increase in Contracted Backlog in the third quarter of 2022 resulted from quarterly bookings of $223 million, partially offset by revenue recognition, contract cancellations, and amendments. Bookings of $223 million in the third quarter of 2022 increased by 115% year-over-year versus $104 million in third quarter 2021.

Third quarter 2022 contracted storage AUM increased 71% year-over-year and 14% sequentially to 2.4 GWh, driven by new contracts.

Third quarter 2022 solar monitoring AUM was 25 GW, down 7 GW sequentially. This decline was the result of actions commencing in the third quarter, as AlsoEnergy began to migrate or terminate a legacy-acquired software application, primarily used in Europe, that was unprofitable. These terminations are not expected to have a material impact on our recurring revenue, will have limited impact on our storage retrofit opportunity, and are expected to be accretive to our Non-GAAP Gross Margin in coming quarters.

Third quarter 2022 CARR increased to $61 million, up from $58 million as of the end of the second quarter of 2022, an 5% 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 following table provides a summary of backlog at the end of the third quarter of 2022, compared to backlog at the end of the second quarter of 2022 ($ millions):

End of 2Q22	$	727
Add: Bookings		223
Less: Hardware revenue		(86	)
Software/services		(14	)
Amendments/other		(33	)
End of 3Q22	$	817

The Company continues to diversify its supply chain, adopt alternative technologies, and deploy its balance sheet to position the Company to meet the expected significant growth in customer demand. COVID-19 and its recent subvariants, potential import tariffs, and general economic, geopolitical, and business conditions, including the ongoing conflict between Russia and Ukraine, 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 rising interest rates. The Company is actively working 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 November 3, 2022, the Company announced that it has been ranked #1 for innovation by Frost & Sullivan in its Frost Radar™: Digital Platforms for Renewable Energy and Battery Storage Optimization and Trading report. The report highlighted Stem's cloud-native SaaS platform, which leverages AI and continuous machine learning that fully automates model selection to constantly improve the results of optimization and forecasting.

In October 2022, the Company began producing control and monitoring hardware for its energy storage customers at its Longmont, Colorado facility. The Company had historically produced control and monitoring hardware for its AlsoEnergy solar customers in Longmont, but relied on multiple contract manufacturers to build similar hardware for its energy storage customers. The integration of this production is expected to lower costs by more than 30% and result in a power controller that supports the full suite of Athena applications, including PowerTrack.

On September 21, 2022, the Company announced the appointment of Michael Carlson as its Chief Operating Officer. Carlson brings 30 years of experience in technology, operations management, and finance across multiple industries, and 20 years of energy expertise at Koch Industries, General Electric, Siemens, and ABB. Carlson is responsible for the Company's day-to-day operations, program execution, deployment, and manufacturing.

On September 20, 2022, the Company announced a partnership with InCharge Energy, a fleet electrification services leader, to equip businesses with a complete electric vehicle (EV) fleet infrastructure solution to maximize the value of their charging assets. When integrated with InCharge's platform, Athena will provide EV fleet customers with interoperable clean energy systems, protection from outages, accurate project economic forecasts, reduced utility bills, vehicle-to-grid enablement, and greenhouse gas emissions tagging.

On September 9, 2022, the Company announced that its California virtual power plant dispatched approximately 86 megawatts (MW) and 268 megawatt-hours (MWh) over the five-hour "Flex Alert" period on September 6, 2022, equivalent to over 100,000 homes. California utilities instituted Flex Alerts over multiple days in August and September 2022 in response to an extreme statewide heat wave and electric grid emergency. In total, the Company dispatched 1,760 MWh during seven Flex Alert days in August and September 2022.

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. 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."

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. Our 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.

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 2022 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 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 2022 GAAP financial results.

(1) Adjusted EBITDA for the three and nine months ended September 30, 2021 reflects adjustments to depreciation and amortization of approximately $0.7 million and $1.9 million, respectively, for expenses related to impairments, decommissioning and forfeited incentives that were not previously reflected.

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

	Three Months Ended September 30,						Nine Months Ended September 30,
	2022			2021			2022			2021
Revenue	$	99.5		$	39.8		$	207.5		$	74.6
Cost of revenue		(90.4	)		(36.7	)		(187.0	)		(71.7	)
GAAP Gross Margin		9.1			3.1			20.5			2.9
GAAP Gross Margin (%)		9	%		8	%		10	%		4	%

Adjustments to Gross Margin:
Amortization of Capitalized Software & Developed Technology		2.9			1.4			7.6			3.8
Impairments		0.4			0.7			2.2			2.0
Non-GAAP Gross Margin	$	12.4		$	5.2		$	30.3		$	8.7
Non-GAAP Gross Margin (%)		13	%		13	%		15	%		12	%

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 2022 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 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 2022 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 valuable metric because it provides visibility into the long-term growth in the Company's high-margin software revenue.
