Stem, Inc. ("Stem" or the "Company") (NYSE:STEM), a global leader in artificial intelligence (AI)-driven energy software and services, announced today its financial results for the three and 12 months ended December 31, 2021. All reported results included in this release do not reflect the acquisition of AlsoEnergy, which closed on February 1, 2022.

John Carrington, Chief Executive Officer of Stem, commented, "We reported another strong quarter with record revenues, backlog, pipeline and AUM, all driven by our market-leading Athena platform. Our contracted backlog grew sequentially by 44% during the quarter, driven by a record $217 million in bookings. For the full-year 2021, revenues grew 251% to $127 million, and bookings grew 202% to $417 million, bolstering our contracted backlog, which grew 144% year-over-year and provides strong momentum into 2022 and beyond.

"As part of our continued focus on our software platforms, Athena and AlsoEnergy's PowerTrack, we plan to add a sixth key metric to our reporting stack with the addition of contracted annual recurring revenue or "CARR". The metric will provide visibility to the growth in our software and services base as we continue to build existing markets and enter new ones. We believe CARR, estimated to be between $60M - $80M for 2022, when combined with our historically low churn, will provide a long-term view to our anticipated growth in services revenue.

"As previously announced, we completed the AlsoEnergy transaction earlier this month. The transaction is transformational, as it combines two of the leading renewable energy software platforms to provide best in class services to the fast-growing renewable energy industry. With our common mission critical software offerings, we provide high value solutions which enhances revenues and manage costs for renewable energy projects across the globe.

"Supply chain, permitting and interconnection delays negatively impacted our fourth quarter revenues, but demand remains robust, and we expect these issues to resolve over time. We are pleased to introduce our 2022 revenue guidance range, inclusive of AlsoEnergy, which at the midpoint implies we will more than triple our revenues again this year. In addition, we are on track to execute on bookings in excess of $1 billion between July 2021 and December 2022. Our differentiated software offering, customer-focused employees, and strong balance sheet provide visibility into our anticipated multi-year growth in recurring software revenues."

Fourth Quarter and Full-Year 2021 Financial and Operating Results

Financial Results

Fourth quarter 2021 revenue increased 184% to a record $52.8 million, versus $18.6 million in the fourth quarter of 2020. Full-year 2021 revenue increased 251% to a record $127.4 million versus $36.3 million in full-year 2020. Higher hardware revenue from Front of the Meter ("FTM") and Behind the Meter ("BTM") partnership agreements drove most of the increase for the quarter and the year, in addition to higher services revenue driven by increased adoption of the Athena platform.

Fourth quarter 2021 GAAP Gross Margin was $(1.6) million, or (3)%, versus $0.9 million, or 5% in the fourth quarter of 2020, and $3.1 million, or 8%, in the third quarter of 2021. Full-year 2021 GAAP Gross Margin was $1.2 million, or 1%, versus full-year 2020 GAAP Gross Margin of $(3.9) million, or (11)%. The year-over-year decrease in GAAP Gross Margin for the fourth quarter resulted primarily from a higher level of non-cash impairments. The year-over-year increase in GAAP Gross Margin for the full year resulted from additional high margin services revenues.

Fourth quarter 2021 Non-GAAP Gross Margin was $3.3 million, or 6% versus $2.5 million, or 13% in the fourth quarter of 2020, and $5.8 million, or 15%, in the third quarter of 2021. Full-year 2021 Non-GAAP Gross Margin was $14.0 million, or 11%, versus full-year 2020 Non-GAAP Gross Margin of $3.5 million, or 10%.

The year-over-year increase in Non-GAAP Gross Margin for the fourth quarter and full year resulted from higher revenues. In percentage terms for the fourth quarter, the year-over-year decrease in Non-GAAP Gross Margins resulted from a higher mix of hardware deliveries. In percentage terms for the full year, the year-over-year increase resulted from higher services revenue.

Fourth quarter 2021 Net Loss was $(34.1) million versus fourth quarter 2020 Net Loss of $(100.9) million. Full-year 2021 Net Loss was $(101.2) million versus full-year 2020 Net Loss of $(156.1) million. For the quarter and the year, the differences were primarily driven by non-cash revaluation of warrants, tied to changes in the value of the underlying common stock.

Fourth quarter 2021 Adjusted EBITDA was $(12.4) million compared to $(5.1) million in the fourth quarter of 2020. Full-year 2021 Adjusted EBITDA was $(30.3) million compared to $(25.4) million in full-year 2020. The lower Adjusted EBITDA results were primarily driven by higher operating expenses due to increased personnel costs reflecting continued investment in our growth initiatives and costs associated with public reporting requirements.

The Company ended the fourth quarter 2021 with $921 million in cash, consisting of $748 million in cash and cash equivalents and $173 million in short-term investments. The sequential increase from $576 million in cash at the end of third quarter 2021 was primarily the result of the issuance of $460 million of our 0.50% Green Convertible Senior Notes due 2028, net of discounts, fees and the purchase of capped call options.

Operating Results

The Company's 12-month forward pipeline was $4.0 billion at the end of the fourth quarter compared to $2.4 billion at the end of the third quarter, representing 67% sequential growth. The increase in the 12-month pipeline is a result of increased FTM project opportunities, including significant expansions into new markets, continued growth in Stem's partner channel, and the seasonal nature of the pipeline.

Contracted Backlog was $449 million as of December 31, 2021 compared to $312 million as of September 30, 2021, representing a 44% sequential increase. The increase in Contracted Backlog resulted from record bookings in the quarter of $217 million, partially offset by revenue recognition, contract cancellations and amendments during the quarter. For the fourth quarter 2021, bookings grew 400% year-over-year from $43 million in fourth quarter 2020. Full year 2021 bookings of $416.5 million were more than three times higher than full-year 2020 bookings of $137.7 million.

Contracted AUM increased 60% year-over-year and 14% sequentially to 1.6 GWh, driven by new contracts.

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

Period ended 3Q21		$312
Add: Bookings		217
Less: Hardware revenue		(47)
Cancellations		(24)
Amendments/other		(9)
Period ended 4Q21		$449

The Company expects to continue to diversify its supply chain, adopt alternative technologies, and deploy its balance sheet to meet the expected significant growth in customer demand. COVID-19 and general macroeconomic conditions continue to impact the supply chain and project timelines, and the Company has been affected by inflation in the costs of equipment. The Company is actively working to mitigate these impacts on its financial results.

Business Highlights

On February 24, 2022, the Company announced that it had been exclusively selected to provide storage solutions to Available Power, a developer of distributed energy resources. The strategic partnership will develop up to 100 FTM sites in Texas with potential to provide one gigawatt (GW), or two GWh, of energy storage systems and Athena software. The portfolio will be completed in phases, with deployment of the first 20 systems by early 2023.

On February 1, 2022, the Company completed its previously-announced acquisition of AlsoEnergy Holdings, Inc. ("AlsoEnergy") for $695 million in a combination of cash and Stem common stock. AlsoEnergy is a global leader in solar asset management software, with 33 gigawatts (GW) of assets under management in more than 50 countries. In the fiscal year ended December 31, 2020, AlsoEnergy generated approximately $49 million in revenue and realized 60% gross margin across its software, grid edge monitoring, controls, and services businesses. AlsoEnergy will continue to operate under its own brand and provide the same services to its customers.

On January 5, 2022, the Company announced that it had entered into a co-marketing agreement with ENGIE North America to develop an offering to enable eMobility solutions. The offering will combine Stem's Athena software and storage hardware with ENGIE's charging, energy management, and onsite generation solutions.

On November 22, 2021, the Company sold $460 million aggregate principal amount of its 0.50% Green Convertible Senior Notes due 2028 (the "Notes") in a private placement. In connection with the sale of the Notes, Stem entered into capped call transactions to reduce potential dilution to Stem's common stock upon any conversion of the Notes, with a cap price of $49.66 per share. Stem's net proceeds from this offering were approximately $445.7 million. Stem used approximately $67 million of the net proceeds to pay the cost of the capped call transactions.

Outlook

The Company is introducing full-year 2022 financial guidance as follows ($ millions unless otherwise noted):

Revenue		$350 - $425
Non-GAAP Gross Margin (%)		15%- 20%
Adjusted EBITDA		$(60) - $(20)
Bookings		$650 - $750
CARR (yearend)		$60 - $80

The Company is introducing 2022 seasonality guidance indicating quarterly projected performance against the annual targets as follows:

Metric	Q1	Q2	Q3	Q4
Revenue	7.5%	15.0%	22.5%	55.0%
Bookings	20%	20%	25%	35%

Stem's 2022 guidance includes the operations of AlsoEnergy effective February 1, 2022.

Use of Non-GAAP Financial Measures

In addition to financial results determined in accordance with U.S. generally accepted accounting principles ("GAAP"), this fourth-quarter and full-year 2021 earnings release contains the following non-GAAP financial measures: non-GAAP gross margin and Adjusted EBITDA. The foregoing 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 non-GAAP gross margin and Adjusted EBITDA to their 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 our institutional investors and the analyst community to help them analyze the health of our business.

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 the change in fair value of warrants and embedded derivatives, loss on extinguishment of debt, and income taxes.

We define non-GAAP gross margin as gross margin excluding amortization of capitalized software, impairments related to decommissioning of end-of-life systems, and adjustments to reclassify data communication and cloud production expenses to operating expenses. See the definitions of non-GAAP metrics at the end of the press release.

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 forward-looking reconciliation of 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.

Adjusted EBITDA for the full years 2021 and 2020 now reflect adjustments to depreciation and amortization of approximately $2.0 and $3.1 million, respectively, for expenses related to impairments, decommissioning and forfeited incentives that were not previously reflected.
