NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

(Dollar amounts in thousands, except per share data, unless otherwise noted)

1.General

Company Overview

Altus Power, Inc., a Delaware corporation (the “Company” or "Altus"), headquartered in Stamford, Connecticut, develops, owns, constructs and operates large-scale roof, ground and carport-based photovoltaic solar energy generation and storage systems, for the purpose of producing and selling electricity to credit worthy counterparties, including commercial and industrial, public sector and community solar customers, under long-term contracts. The Solar energy facilities are owned by the Company in project specific limited liability companies (the “Solar Facility Subsidiaries”).

On December 9, 2021 (the "Closing Date"), CBRE Acquisition Holdings, Inc. ("CBAH"), a special purpose acquisition company, consummated the business combination pursuant to the terms of the business combination agreement entered into on July 12, 2021 (the "Business Combination Agreement"), whereby, among other things, CBAH Merger Sub I, Inc. ("First Merger Sub") merged with and into Altus Power, Inc. (f/k/a Altus Power America, Inc.) ("Legacy Altus") with Legacy Altus continuing as the surviving corporation, and immediately thereafter Legacy Altus merged with and into CBAH Merger Sub II, Inc. ("Second Merger Sub") with Second Merger Sub continuing as the surviving entity and as a wholly owned subsidiary of CBAH (together with the merger with the First Merger Sub, the “Merger”). In connection with the closing of the Merger, CBAH changed its name to "Altus Power, Inc." and CBAH Merger Sub II (after merger with Legacy Altus) changed its name to "Altus Power, LLC."

COVID-19

The spike of a novel strain of coronavirus (“COVID-19”) in the first quarter of 2020 caused significant volatility in the U.S. markets that remains ongoing. In response to the COVID-19 pandemic, federal, state, local, and foreign governments put in place, and in the future may again put in place, travel restrictions, quarantines, “stay at home” orders and guidelines, and similar government orders and restrictions, in an attempt to control the spread of the disease. Such restrictions or orders resulted in, and in the future may result in, business closures, work stoppages, slowdowns and delays, among other effects that negatively impacted, and in the future may negatively impact, our operations, as well as the operations of our customers and business partners. In addition, COVID-19 has caused disruptions to the supply chain across the global economy, including within the solar industry, and we are working with our equipment suppliers to minimize disruptions to our operations. Certain suppliers have experienced, and may continue to experience, delays and increased costs related to a variety of factors, including logistical delays and component shortages from upstream vendors. Based on the challenges described above, such as supply chain and logistical delays, such results have had and will continue to have a material adverse effect on our business, operations, financial condition, results of operations, and cash flows.

2.Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The Company prepares its unaudited condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and regulations of the U.S. Securities and Exchange Commission ("SEC") for interim financial reporting. The Company’s condensed consolidated financial statements include the results of wholly-owned and partially-owned subsidiaries in which the Company has a controlling interest. All intercompany balances and transactions have been eliminated in consolidation.

Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2021 filed with the Company’s 2021 annual report on Form 10-K on March 24, 2022, and the related notes which provide a more complete discussion of the Company’s accounting policies and certain other information. The information as of December 31, 2021, included in the condensed consolidated balance sheets was derived from the Company’s audited consolidated financial statements. The condensed consolidated financial statements were prepared on the same basis as the audited consolidated financial statements and reflect all adjustments, including normal recurring adjustments, which are, in the opinion of management, necessary for a fair statement of the Company’s financial position as of September 30, 2022, and the results of operations and cash flows for the three and nine months ended September 30, 2022, and

2021. The results of operations for the three and nine months ended September 30, 2022, are not necessarily indicative of the results that may be expected for the full year or any other future interim or annual period.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates.

In recording transactions and balances resulting from business operations, the Company uses estimates based on the best information available. Estimates are used for such items as the fair value of net assets acquired in connection with accounting for business combinations, the useful lives of the solar energy facilities, and inputs and assumptions used in the valuation of asset retirement obligations (“AROs”), contingent consideration, and alignment shares.

Segment Information

Operating segments are defined as components of a company about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company’s chief operating decision makers are the co-chief executive officers. Based on the financial information presented to and reviewed by the chief operating decision makers in deciding how to allocate the resources and in assessing the performance of the Company, the Company has determined it operates as a single operating segment and has one reportable segment, which includes revenue under power purchase agreements, revenue from net metering credit agreements, solar renewable energy certificate revenue, rental income, performance-based incentives, and other revenue. The Company’s principal operations, revenue and decision-making functions are located in the United States.

Cash, Cash Equivalents, and Restricted Cash

Cash and cash equivalents includes all cash balances on deposit with financial institutions and readily marketable securities with original maturity dates of three months or less at the time of acquisition that are denominated in U.S. dollars. Pursuant to the budgeting process, the Company maintains certain cash and cash equivalents on hand for possible equipment replacement related costs.

The Company records cash that is restricted as to withdrawal or use under the terms of certain contractual agreements as restricted cash. Restricted cash is included in current portion of restricted cash and restricted cash, noncurrent portion on the condensed consolidated balance sheets and includes cash held with financial institutions for cash collateralized letters of credit pursuant to various financing and construction agreements.

The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the condensed consolidated balance sheets. Cash, cash equivalents, and restricted cash consist of the following:

	As of September 30, 2022		As of December 31, 2021
Cash and cash equivalents	$	290,894	$	325,983
Current portion of restricted cash	2,477		2,544
Restricted cash, noncurrent portion	4,018		1,794
Total	$	297,389	$	330,321

Concentration of Credit Risk

The Company maintains its cash in bank deposit accounts which, at times, may exceed Federal Deposit Insurance Corporation insurance limits. The Company has not experienced any losses in such accounts and believes it is not exposed to any significant credit risk on cash balances.

The Company had one customer that individually accounted for 31.5% of total accounts receivable as of September 30, 2022. The Company had one customer that individually accounted for 19.8% of total revenue for the three months ended

September 30, 2022. The Company had one customer that individually accounted for 13.8% of total revenue for the nine months ended September 30, 2022.

The Company had two customers that individually accounted for 16.0% and 11.7% of total accounts receivable as of December 31, 2021. The Company had one customer that individually accounted for 11.7% of total revenue for the three months ended September 30, 2021. The Company had no customers that individually accounted for over 10% of total revenue for the nine months ended September 30, 2021.

Accounting Pronouncements

As a public company, the Company is provided the option to adopt new or revised accounting guidance as an “emerging growth company” under the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) either (1) within the same periods as those otherwise applicable to public business entities, or (2) within the same time periods as non-public business entities, including early adoption when permissible. The Company expects to elect to adopt new or revised accounting guidance within the same time period as non-public business entities, as indicated below.

Recent Accounting Pronouncements Adopted

In December 2019, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2019-12, Income Taxes (Topic 740), which simplifies the accounting for income taxes, primarily by eliminating certain exceptions to ASC 740. This standard is effective for fiscal periods beginning after December 15, 2020. The Company has adopted this standard as of the first quarter of 2021 and did not have a material impact on the condensed consolidated financial statements.

Recent Accounting Pronouncements Not Yet Adopted

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which primarily changes the lessee’s accounting for operating leases by requiring recognition of lease right-of-use assets and lease liabilities. This standard is effective for annual reporting periods beginning after December 15, 2021. The Company expects to adopt this guidance in fiscal year 2022. The Company is continuing the analysis of the contractual arrangements that may qualify as leases under the new standard and expects the most significant impact will be the recognition of the right-of-use assets and lease liabilities on the consolidated balance sheets.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and has since released various amendments including ASU No. 2019-04. The new standard generally applies to financial assets and requires those assets to be reported at the amount expected to be realized. The ASU is effective for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact of this guidance on its consolidated financial statements.

4.Acquisitions and Disposals

2022 Acquisitions and Disposals

Stellar NJ Acquisition

On April 1, 2022, the Company acquired a 1.0 MW solar energy facility located in New Jersey (the "Stellar NJ Acquisition") from a third party for a total purchase price of $1.3 million. The transaction was accounted for as an acquisition of assets, whereby the Company acquired $2.3 million of property, plant and equipment and assumed $0.4 million of intangible liabilities and $0.6 million of other liabilities. The intangible liability assumed is associated with an unfavorable rate power purchase agreement and has a weighted average amortization period of 15 years.

Stellar HI 2 Acquisition

On June 10, 2022, the Company acquired a 4.6 MW portfolio of six solar energy facilities located in Hawaii (the "Stellar HI 2 Acquisition") from a third party for a total purchase price of $9.9 million, including $0.2 million of transaction related costs. This transaction was accounted for as an acquisition of assets, whereby the Company acquired $7.3 million of property, plant and equipment and $3.1 million of intangible assets, and assumed $0.5 million of intangible liabilities and $0.1 million of asset retirement obligations.

The Company attributed intangible asset and liability values to favorable and unfavorable rate revenue contracts to sell power generated by the acquired solar energy facilities, as well as a favorable rate lease. The following table summarizes the estimated fair values and the weighted average amortization periods of the acquired intangible assets and assumed intangible liabilities as of the acquisition date:

	Fair Value (thousands)		Weighted Average Amortization Period
Favorable rate revenue contracts	$	2,903	10 years
Site lease acquisition	229		15 years
Unfavorable rate revenue contracts	(464)		14 years

Stellar NJ 2 Acquisition

On August 29, 2022, the Company acquired an 8.3 MW portfolio of five solar energy facilities located in New Jersey (the "Stellar NJ 2 Acquisition") from a third party for a total purchase price of $3.4 million, including $1.2 million to be paid over the next two years and $0.2 million of transaction related costs. Four of the acquired solar energy facilities in the transaction were accounted for as an acquisition of assets, and one solar energy facility was accounted for as an acquisition of a variable interest entity that does not constitute a business, refer to Note 5. The Company acquired $17.7 million of property, plant and equipment, $0.1 million of accounts receivable, and $0.4 million of cash, and assumed $11.9 million of long-term debt, $0.6 million of intangible liabilities, $0.2 million of asset retirement obligations, and $2.1 million of noncontrolling interests associated with the acquired variable interest entity. The intangible liabilities assumed are associated with unfavorable rate power purchase agreements and have a weighted average amortization period of 11 years.

Disposal of Land

On August 15, 2022, the Company sold land owned by SP NJ Solar, LLC, a subsidiary of the Company, to a third party for cash consideration of $3.6 million. As of that date, the carrying amount of the land was $1.4 million. The Company recognized a $2.2 million gain on disposal of property, plant and equipment as a result of the transaction.

5.Variable Interest Entity

The Company consolidates all variable interest entities (“VIEs”) in which it holds a variable interest and is deemed to be the primary beneficiary of the variable interest entity. Generally, a VIE is an entity with at least one of the following conditions: (a) the total equity investment at risk is insufficient to allow the entity to finance its activities without additional subordinated financial support, or (b) the holders of the equity investment at risk, as a group, lack the characteristics of having a controlling financial interest. The primary beneficiary of a VIE is required to consolidate the VIE and to disclose certain information about its significant variable interests in the VIE. The primary beneficiary of a VIE is the entity that has both 1) the power to direct the activities that most significantly impact the entity’s economic performance and 2) the obligations to absorb losses or receive benefits that could potentially be significant to the VIE.

The Company participates in certain partnership arrangements that qualify as VIEs. Consolidated VIEs consist of tax equity financing arrangements and partnerships in which an investor holds a noncontrolling interest and does not have substantive kick-out or participating rights. The Company, through its subsidiaries, is the primary beneficiary of such VIEs, because as the manager, it has the power to direct the day-to-day operating activities of the entity. In addition, the Company is exposed to economics that could potentially be significant to the entity given its ownership interest, and, therefore, has consolidated the VIEs as of September 30, 2022, and December 31, 2021. No VIEs were deconsolidated during the nine months ended September 30, 2022 and 2021.

The obligations of the consolidated VIEs discussed in the following paragraphs are nonrecourse to the Company. In certain instances where the Company establishes a new tax equity structure, the Company is required to provide liquidity in accordance with the contractual agreements. The Company has no requirement to provide liquidity to purchase assets or guarantee performance of the VIEs unless further noted in the following paragraphs. The Company made certain contributions during the nine months ended September 30, 2022 and 2021, as determined in the respective operating agreement.

The carrying amounts and classification of the consolidated VIE assets and liabilities included in condensed consolidated balance sheets are as follows:

	As of September 30, 2022		As of December 31, 2021
Current assets	$	17,356	$	13,131
Non-current assets	378,099		372,761
Total assets	$	395,455	$	385,892
Current liabilities	$	3,525	$	3,652
Non-current liabilities	40,821		40,978
Total liabilities	$	44,346	$	44,630

The amounts shown in the table above exclude intercompany balances which are eliminated upon consolidation. All of the assets in the table above are restricted for settlement of the VIE obligations, and all of the liabilities in the table above can only be settled using VIE resources.

The Company has not identified any VIEs during the nine months ended September 30, 2022 and 2021, for which the Company determined that it is not the primary beneficiary and thus did not consolidate.

The Company considered qualitative and quantitative factors in determining which VIEs are deemed significant. During each of the nine months ended September 30, 2022 and the year ended December 31, 2021, the Company consolidated twenty-six and twenty-five VIEs, respectively. No VIEs were deemed significant as of September 30, 2022 and December 31, 2021.

As discussed in Note 4, on August 29, 2022, the Company completed the Stellar NJ 2 Acquisition, including the acquisition of a controlling financial interest in a VIE which owns and operates a single 1.1 MW solar generating facility. The Company acquired a controlling financial interest by entering into an asset management agreement which provides the Company with the power to direct the operating activities of the VIE and the obligation to absorb losses or receive benefits that could potentially be significant to the VIE. The asset management agreement also includes a call and put option to acquire the equity interest in June 2023 and January 2024, respectively. As a result of this acquisition, the Company recognized property, plant and equipment of $2.6 million, intangible liability of $0.2 million, and noncontrolling interest of $2.1 million in the unaudited condensed consolidated balance sheet.

Amended Rated Term Loan

As part of the Blackstone Capital Facility, APA Finance, LLC (“APAF”), a wholly owned subsidiary of the Company, entered into a $251.0 million term loan facility with Blackstone Insurance Solutions ("BIS") through a consortium of lenders, which consists of investment grade-rated Class A and Class B notes (the "Rated Term Loan").

On August 25, 2021, APAF entered into an Amended and Restated Credit Agreement with BIS to refinance the Rated Term Loan (the “Amended Rated Term Loan”). The Amended Rated Term Loan added $135.6 million to the facility, bringing the aggregate facility to $503.0 million. The Amended Rated Term Loan has a weighted average 3.51% annual fixed rate, reduced from the previous weighted average rate of 3.70%, and matures on February 29, 2056 (“Final Maturity Date”).

The Amended Rated Term Loan amortizes at an initial rate of 2.5% of outstanding principal per annum for a period of 8 years at which point the amortization steps up to 4% per annum until September 30, 2031 (“Anticipated Repayment Date”). After the Anticipated Repayment Date, the loan becomes fully-amortizing, and all available cash is used to pay down principal until the Final Maturity Date.

As of September 30, 2022, the outstanding principal balance of the Rated Term Loan was $490.3 million less unamortized debt discount and loan issuance costs totaling $7.8 million. As of December 31, 2021, the outstanding principal balance of the Rated Term Loan was $500.0 million less unamortized debt discount and loan issuance costs totaling $8.4 million.

As of September 30, 2022, the Company was in compliance with all covenants. As of December 31, 2021, the Company was in compliance with all covenants, except the delivery of the APAF audited consolidated financial statements, for which the Company obtained a waiver to extend the financial statement reporting deliverable due date. The Company delivered the audited financial statements on May 25, 2022, before the extended reporting deliverable due date.

Construction to Term Loan Facility

On January 10, 2020, APA Construction Finance, LLC (“APACF”) a wholly-owned subsidiary of the Company, entered into a credit agreement with Fifth Third Bank, National Association and Deutsche Bank AG New York Branch to fund the development and construction of future solar facilities (“Construction Loan to Term Loan Facility”). The Construction Loan to Term Loan Facility includes a construction loan commitment of $187.5 million and a letter of credit commitment of $12.5 million, which can be drawn until January 10, 2023.

The construction loan commitment can convert to a term loan upon commercial operation of a particular solar energy facility. In addition, the Construction Loan to Term Loan Facility accrued a commitment fee at a rate equal to 0.50% per year of the daily unused amount of the commitment. As of September 30, 2022, the outstanding principal balances of the construction loan and term loan were zero and $16.0 million, respectively. As of December 31, 2021, the outstanding principal balances of the construction loan and term loan were $5.6 million and $12.3 million, respectively. As of September 30, 2022, and December 31, 2021, the Company had an unused borrowing capacity of $171.5 million and $169.7 million, respectively. For the three months ended September 30, 2022, and 2021, the Company incurred interest costs associated with outstanding construction loans totaling zero and $0.1 million, respectively. For the nine months ended September 30, 2022, and 2021 the Company incurred interest costs associated with outstanding construction loans totaling zero and $0.4 million, respectively. These interest costs were capitalized as part of property, plant and equipment. The Construction Loan to Term Loan Facility includes various financial and other covenants for APACF and the Company, as guarantor. As of September 30, 2022, and December 31, 2021, the Company was in compliance with all covenants.

Project-Level Term Loan

In conjunction with the Stellar NJ 2 Acquisition, the Company assumed a project-level term loan with an outstanding principal balance of $14.1 million and a fair value discount of $2.2 million. The term loan is subject to scheduled semi-annual amortization and interest payments, and matures on September 1, 2029.

As of September 30, 2022, the outstanding principal balance of the term loan is $12.6 million, less unamortized debt discount of $2.2 million, which was recognized as part of the acquisition. During the nine months ended September 30, 2022, the Company incurred interest costs associated with the term loan of $0.2 million.

The term loan is secured by an interest in the underlying solar project assets and the revenues generated by those assets. As of September 30, 2022, the Company was in compliance with all covenants.

Letter of Credit Facilities

On October 23, 2020, the Company entered into a letter of credit facility with Fifth Third Bank for the total capacity of $10.0 million. Additionally, in conjunction with the Stellar NJ 2 Acquisition, the Company entered into a cash collateralized letter of credit with Fifth Third Bank with a total capacity of $2.1 million.

As of September 30, 2022, and December 31, 2021, the total letters of credit outstanding with Fifth Third Bank were $12.1 million with an unused capacity of zero. As of September 30, 2022, and December 31, 2021, the total letters of credit outstanding with Deutsche Bank were $0.7 million and $0.6 million, respectively, with an unused capacity of $11.8 million and $11.9 million, respectively. To the extent liabilities are incurred as a result of the activities covered by the letters of credit, such liabilities are included on the accompanying condensed consolidated balance sheets. From time to time, the Company is required to post financial assurances to satisfy contractual and other requirements generated in the normal course of business. Some of these assurances are posted to comply with federal, state or other government agencies’ statutes and regulations. The Company sometimes uses letters of credit to satisfy these requirements and these letters of credit reduce the Company’s borrowing facility capacity.

Financing Lease Obligations

From time to time, the Company sells equipment to third parties and enters into master lease agreements to lease the equipment back for an agreed-upon term. Due to certain forms of continuous involvement provided by the master lease agreements, sale leaseback accounting is prohibited under ASC 840. Therefore, the Company accounts for these transactions using the financing method by recognizing the sale proceeds as a financing obligation and the assets subject to the sale-leaseback remain on the balance sheet of the Company and are being depreciated. The aggregate proceeds have been recorded as long-term debt within the condensed consolidated balance sheets.

As of September 30, 2022 and December 31, 2021, the Company's recorded financing obligations were $36.0 million, net of $1.1 million of deferred transaction costs, and $36.5 million, net of $1.1 million of deferred transaction costs, respectively. Payments of $0.9 million and $0.1 million were made under financing lease obligations for the three months ended September 30, 2022, and 2021, respectively. Payments of $1.5 million and $0.1 million were made under financing obligations for the nine months ended September 30, 2022 and 2021, respectively. Interest expense, inclusive of the amortization of deferred transaction costs, for the three months ended September 30, 2022, and 2021, was $0.4 million and $0.2 million, respectively. Interest expense, inclusive of the amortization of deferred transaction costs, for the nine months ended September 30, 2022 and 2021, was $1.1 million and $0.2 million, respectively.

The table below shows the minimum lease payments under the financing lease obligations for the years ended:

2022	$	709
2023	2,336
2024	2,340
2025	2,353
2026	2,336
Thereafter	14,993
Total	$	25,067

The difference between the outstanding financing lease obligation of $37.1 million and $25.1 million of minimum lease payments, including the residual value guarantee, is due to $13.2 million of investment tax credits claimed by the Lessor, less $2.6 million of the implied interest on financing lease obligation included in minimum lease payments. The remaining difference is due to $1.3 million of interest accrued and a $0.1 million difference between the minimum lease payments and the fair value of financing lease obligations acquired.

7.Fair Value Measurements

The Company measures certain assets and liabilities at fair value, which is defined as the price that would be received from the sale of an asset or paid to transfer a liability (i.e., an exit price) on the measurement date in an orderly transaction between

(Dollar amounts in thousands, except per share data, unless otherwise noted)

market participants in the principal or most advantageous market for the asset or liability. Our fair value measurements use the following hierarchy, which prioritizes valuation inputs based on the extent to which the inputs are observable in the market.

•Level 1 - Valuation techniques in which all significant inputs are unadjusted quoted prices from active markets for assets or liabilities that are identical to the assets or liabilities being measured.

•Level 2 - Valuation techniques in which significant inputs include quoted prices from active markets for assets or liabilities that are similar to the assets or liabilities being measured and/or quoted prices for assets or liabilities that are identical or similar to the assets or liabilities being measured from markets that are not active. Also, model-derived valuations in which all significant inputs are observable in active markets are Level 2 valuation techniques.

•Level 3 - Valuation techniques in which one or more significant inputs are unobservable. Such inputs reflect our estimate of assumptions that market participants would use to price an asset or liability.

The Company holds various financial instruments that are not required to be recorded at fair value. For cash, restricted cash, accounts receivable, accounts payable, and short-term debt, the carrying amounts approximate fair value due to the short maturity of these instruments.

Redeemable Warrant Liability

CBAH sold 10,062,500 warrants as part of the SAILSM (Stakeholder Aligned Initial Listing) securities in the CBAH initial public offering (which traded separately on the NYSE under the symbol “CBAH WS” prior to the Merger, and following the Merger trade under the symbol “AMPS WS”) (such warrants, the "Redeemable Warrants"). The Redeemable Warrants are exercisable for an aggregate of 10,062,500 shares of the Company's Class A common stock, par value $0.0001 per share (the "Class A common stock"), at a purchase price of $11.00 per share. CBAH also issued 7,366,667 warrants to CBRE Acquisition Sponsor, LLC (the “Sponsor”) in a private placement simultaneously with the closing of the CBAH IPO and 2,000,000 warrants to the Sponsor in full settlement of a second amended and restated promissory note with the Sponsor (such warrants, the "Private Placement Warrants"). The Private Placement Warrants are identical to the Redeemable Warrants except that, so long as they are held by the Sponsor, officers or directors or their respective permitted transferees, (i) they will not be redeemable by the Company (except in certain circumstances), (ii) they may be exercised by the holders on a cashless basis, and (iii) they (including the shares of our Class A common stock issuable upon exercise of these warrants) are entitled to registration rights. If the Private Placement Warrants are held by holders other than the Sponsor, officers or directors or their respective permitted transferees, the Private Placement Warrants will become redeemable by the Company in all redemption scenarios and exercisable by the holders on the same basis as the Redeemable Warrants. The Private Placement Warrants will be exercisable for an aggregate of 9,366,667 shares of CBAH Class A common stock at a purchase price of $11.00 per share.

Redeemable warrants, including Private Placement Warrants, are not considered to be “indexed to the Company’s own stock.” This provision precludes the Company from classifying the Redeemable warrants, including Private Placement Warrants, in stockholders’ equity. As the Redeemable warrants, including Private Placement Warrants, meet the definition of a derivative, the Company recorded these warrants as liabilities on the condensed consolidated balance sheet at fair value, with subsequent changes in their respective fair values recognized in the consolidated statements of operations at each reporting date.

On May 31, 2022, June 15, 2022, and August 17, 2022, and the Company entered into separate, privately negotiated warrant exchange agreements (the "Exchange Agreements") with a limited number of holders of the Company's outstanding Redeemable Warrants. Pursuant to the Exchange Agreements, the Company agreed to issue an aggregate of 1,111,243 shares of Class A common stock to the holders of Redeemable Warrants in exchange for the surrender and cancellation of an aggregate of 4,630,163 Redeemable Warrants. The issuance by the Company of the shares of Common Stock in exchange for the surrender and cancellation of the Redeemable Warrants was made in reliance on the exemption from registration in Section 3(a)(9) of the Securities Act. Immediately prior to the exchange, the Redeemable Warrants were remeasured to fair value based on the trading price of the exchanged shares of common stock, resulting in a gain on fair value remeasurement of $4.1 million within operating income in the condensed consolidated statements of operations for the nine months ended September 30, 2022, and a redeemable warrant liability of $7.8 million, which was then reclassified to additional paid-in capital in the condensed consolidated balance sheet as of September 30, 2022.

On September 15, 2022, the Company issued a notice for redemption of all 14,798,981 of the Company's outstanding Redeemable Warrants at 5:00 p.m. New York City time on October 17, 2022 (the “Redemption Date”) for a redemption price of $0.10 per Warrant (the “Redemption Price”). Holders could elect to exercise their Warrants on a “cashless basis” and surrender

(Dollar amounts in thousands, except per share data, unless otherwise noted)

the Redeemable Warrants for that number of shares of Class A Common Stock that is determined by reference to the table set forth in Section 6.2 of the Warrant Agreement based on the Redemption Date and the Redemption Fair Market Value of $10.98. Given the Redemption Fair Market Value and the Redemption Date, the number of shares of Class A Common Stock to be issued for each Redeemable Warrant that is exercised through a cashless exercise is 0.2763.

As of September 30, 2022, holders of 1,687 Redeemable Warrants exercised their Redeemable Warrants with the payment of cash and the Company received $18,557 of cash proceeds. Holders of 10,614,564 Redeemable Warrants exercised their Redeemable Warrants on a cashless basis in exchange for 2,932,779 shares of Class A Common Stock per Redeemable Warrants. Immediately prior to the exercise, the Redeemable Warrants were remeasured to fair value based on the trading price of the exchanged shares of common stock, resulting in a loss on fair value remeasurement of $8.6 million within operating income in the condensed consolidated statements of operations for the nine months ended September 30, 2022, and a redeemable warrant liability of $35.8 million, which was then reclassified to additional paid-in capital in the condensed consolidated balance sheet as of September 30, 2022.

As the remaining Redeemable Warrants (other than our Private Placement Warrants) continue to trade separately on the NYSE following the Merger as of September 30, 2022, the Company determines the fair value of the Redeemable Warrants based on the quoted trading price of those warrants. As the inputs are observable and reflect quoted trading price, the overall fair value measurement of the Redeemable Warrants, excluding Private Placement Warrants, is classified as Level 1. The Private Placement Warrants have the same redemption and make-whole provisions as the Redeemable Warrants. Therefore, the fair value of the Private Placement Warrants is equal to the Redeemable Warrants. Private Placement Warrants are considered Level 2 as they are measured at fair value using observable inputs for similar assets in an active market.

As of the Redemption Date, holders of 8,462 Redeemable Warrants exercised their Redeemable Warrants with the payment of cash and the Company received $93,082 of cash proceeds. Holders of 14,690,310 Redeemable Warrants exercised their Redeemable Warrants on a cashless basis in exchange for 4,058,845 shares of Class A Common Stock per Redeemable Warrant. A total of 100,209 Warrants remained unexercised as of the Redemption Date, and the Company redeemed those Warrants for an aggregate redemption price of $10,021. The Redeemable Warrants have been delisted from the NYSE, and there are no Redeemable Warrants left outstanding subsequent to the Redemption Date.

Alignment Shares Liability

As of September 30, 2022, the Company has 1,207,500 alignment shares outstanding, all of which are held by the Sponsor, certain former officers of CBAH (such officers, together with the Sponsor, the “Sponsor Parties”) and former CBAH directors. The alignment shares will automatically convert into shares of Class A common stock based upon the Total Return (as defined in Exhibit 4.4 to our 2021 Annual Report on Form 10-K) on the Class A common stock as of the relevant measurement date over each of the seven fiscal years following the Merger.

Upon the consummation of the Merger, alignment shares have no continuing service requirement and do not create an unconditional obligation requiring the Company to redeem the instruments by transferring assets. In addition, the shares convert to a variable number of Class A common stock depending on the trading price of the Class A common stock and dividends paid/payable to the holders of Class A common stock. Therefore, the shares do not represent an obligation or a conditional obligation to issue a variable number of shares with a monetary value based on any of the criteria in ASC 480, Distinguishing Liabilities From Equity. The Company determined that the alignment shares meet the definition of a derivative because they contain (i) an underlying (Class A common stock price), (ii) a notional amount (a fixed number of Class B common stock), (iii)

21

(Dollar amounts in thousands, except per share data, unless otherwise noted)

no or minimal initial net investment (the Sponsor paid a de minimis amount which is less than the estimated fair value of the shares), and (iv) net settleable through a conversion of the Alignment shares into Class A shares. As such, the Company concluded that the alignment shares meet the definition of a derivative, which will be presented at fair value each reporting period, with changes in fair value recorded through earnings.

The Company estimates the fair value of outstanding alignment shares using a Monte Carlo simulation valuation model utilizing a distribution of potential outcomes based on a set of underlying assumptions such as stock price, volatility, and risk-free interest rate. As volatility of 73% and risk-free interest rate of 4.0% are not observable inputs, the overall fair value measurement of alignment shares is classified as Level 3. Unobservable inputs can be volatile and a change in those inputs might result in a significantly higher or lower fair value measurement of Alignment shares.

Contingent Consideration

Solar Acquisition

In connection with the acquisition of a portfolio of sixteen solar energy facilities with a combined nameplate capacity of 61.5 MW on December 22, 2020 (the "Solar Acquisition"), contingent consideration of up to an aggregate of $10.5 million may be payable upon achieving certain market power rates and actual power volumes generated by the acquired solar energy facilities. The Company estimated the fair value of the contingent consideration for future earnout payments using a Monte Carlo simulation model. Significant assumptions used in the measurement include the estimated volumes of power generation of acquired solar energy facilities during the 18-36-month period since the acquisition date, market power rates during the 36-month period, and the risk-adjusted discount rate associated with the business. As the inputs are not observable, the overall fair value measurement of the contingent consideration is classified as Level 3. Liability for the contingent consideration is included in other long-term liabilities in the condensed consolidated balance sheets at the estimated fair value of $2.7 million and $2.3 million as of September 30, 2022 and December 31, 2021, respectively. For the three and nine months ended September 30, 2022, the Company recorded $0.8 million loss and $0.1 million gain on fair value remeasurement of contingent consideration within operating income in the condensed consolidated statements of operations, respectively. For the three and nine months ended September 30, 2021, the Company recorded $0.4 million and $2.4 million gain on fair value remeasurement of contingent consideration within operating income in the condensed consolidated statements of operations, respectively. Gain and loss was recorded due to changes in significant assumptions used in the measurement, including the actual versus estimated volumes of power generation of acquired solar energy facilities and market power rates.

Other

Gain on fair value remeasurement of other contingent consideration of $0.5 million was recorded within operating income in the condensed consolidated statements of operations for the nine months ended September 30, 2022. No gain or loss on fair value remeasurement of contingent consideration was recorded for the nine months ended September 30, 2021.

8.Equity

As of September 30, 2022, the Company had authorized and issued 988,591,250 and 157,696,560 shares of Class A common stock, respectively. As of December 31, 2021, the Company had authorized and issued 988,591,250 and 153,648,830 shares of Class A common stock, respectively. Class A common stock entitles the holder to one vote on all matters submitted to a vote of the Company’s stockholders. Common stockholders are entitled to receive dividends, as may be declared by the Company’s board of directors. As of September 30, 2022, and December 31, 2021, no common stock dividends have been declared.

10.Commitments and Contingencies

Legal

The Company is a party to a number of claims and governmental proceedings which are ordinary, routine matters incidental to its business. In addition, in the ordinary course of business the Company periodically has disputes with vendors, customers, and other counterparties. The outcomes of any current, pending matters are not expected to have, either individually or in the aggregate, a material adverse effect on the Company’s financial position or results of operations.

Performance Guarantee Obligations

The Company guarantees certain specified minimum solar energy production output under the Company’s PPA agreements, generally over a term of 10, 15 or 25 years. The solar energy systems are monitored to ensure these outputs are achieved. The Company evaluates if any amounts are due to customers based upon not meeting the guaranteed solar energy production outputs at each reporting period end. As of September 30, 2022, and December 31, 2021, the guaranteed minimum solar energy production has been met and the Company has recorded no performance guarantee obligations.

As of September 30, 2022, $0.1 million is due to CBRE and no amounts have been paid by the Company under the MSA.

12.Earnings per Share

The calculation of basic and diluted earnings per share for the three and nine months ended September 30, 2022 and 2021, was as follows (in thousands, except share and per share amounts):

	For the three months ended September 30,				For the nine months ended September 30,
	2022		2021		2022		2021
Net loss attributable to common stockholders - basic and diluted	(96,980)		(1,055)		(12,446)		(1,282)
Class A Common Stock
Weighted average shares of common stock outstanding - basic(1)	154,455,228		88,741,089		153,482,503		88,741,089
Weighted average shares of common stock outstanding - diluted(1)(2)(3)	154,455,228		88,741,089		153,482,503		88,741,089
Net loss attributable to common stockholders per share - basic and diluted	$	(0.63)	$	(0.01)	$	(0.08)	$	(0.01)

(1) The calculation of basic weighted average shares of common stock outstanding excludes 542,511 shares of the Company's Class A common stock provided to holders of Legacy Altus common stock, including shares that were subject to vesting conditions (the "Altus Restricted Shares") for the three and nine months ended September 30, 2022, and 1,259,887 shares of Company Class A common stock provided to holders of Altus Restricted Shares for the three and nine months ended September 30, 2021. The calculation of diluted weighted average shares of common stock for the three and nine months ended September 30, 2022, and 2021, also excludes these shares because their inclusion would have had an anti-dilutive effect.

(2) Excludes 4,182,730 Redeemable Warrants for the three and nine months ended September 30, 2022. The Redeemable Warrants are exercisable at $11.00 per share. As the warrants are deemed anti-dilutive, they are excluded from the calculation of earnings per share.

(3) Excludes 2,323,574 shares of the Company's Class A common stock provided to holders of restricted stock units granted under the Omnibus Incentive Plan for the three and nine months ended September 30, 2022, because their inclusion would have had an anti-dilutive effect.

13.Stock-Based Compensation

The Company recognized $2.7 million and approximately zero of stock-based compensation expense for the three months ended September 30, 2022, and 2021, respectively. The Company recognized $6.7 million and $0.1 million of stock-based compensation expense for the nine months ended September 30, 2022, and 2021, respectively. As of September 30, 2022, and

(Dollar amounts in thousands, except per share data, unless otherwise noted)

December 31, 2021, the Company had $35.9 million and $0.2 million of unrecognized share-based compensation expense related to unvested restricted units, respectively, which the Company expects to recognize over a weighted-average period of approximately five years.

Legacy Incentive Plans

Prior to the Merger, Altus maintained the APAM Holdings LLC Restricted Units Plan, adopted in 2015 (the “APAM Plan”) and APAM Holdings LLC adopted the 2021 Profits Interest Incentive Plan (the “Holdings Plan”, and together with the APAM Plan, the “Legacy Incentive Plans”), which provided for the grant of restricted units that were intended to qualify as profits interests to employees, officers, directors and consultants. In connection with the Merger, vested restricted units previously granted under the Legacy Incentive Plans were exchanged for shares of Class A Common Stock, and unvested Altus Restricted Shares under each of the Legacy Incentive Plans were exchanged for restricted Class A Common Stock with the same vesting conditions. As of September 30, 2022, and December 31, 2021, zero and 446,128 shares of Class A Common Stock were restricted under the APAM Plan, respectively. As of September 30, 2022, and December 31, 2021, 542,511 and 813,759 shares of Class A Common Stock were restricted under the Holdings Plan, respectively. No further awards will be made under the Legacy Incentive Plans.

The fair value of the granted units was determined using the Black-Scholes Option Pricing model and relied on assumptions and inputs provided by the Company. All option models utilize the same assumptions with regard to (i) current valuation, (ii) volatility, (iii) risk-free interest rate, and (iv) time to maturity. The models, however, use different assumptions with regard to the strike price which vary by award.

Omnibus Incentive Plan

On July 12, 2021, the Company entered into the Management Equity Incentive Letter with each of Mr. Felton and Mr. Norell pursuant to which, on February 15, 2022, the Compensation Committee granted to Mr. Felton and Mr. Norell, together with other senior executives, including Anthony Savino, Chief Construction Officer, and Dustin Weber, Chief Financial Officer, restricted stock units (“RSUs”) under the Omnibus Incentive Plan (the "Incentive Plan") that are subject to time-based and, for the named executive officers and certain other executives, eighty percent (80%) of such RSUs also further subject to performance-based vesting, with respect to an aggregate five percent (5%) of the Company’s Class A common stock on a fully diluted basis, excluding the then-outstanding shares of the Company’s Class B common stock or any shares of the Company’s Class A common stock into which such shares of the Company’s Class B common stock are or may be convertible. Subject to continued employment on each applicable vesting date, the time-based RSUs generally vest 33 1/3% on each of the third, fourth and fifth anniversaries of the Closing, and the performance-based RSUs vest with respect to 33 1/3% of the award upon the achievement of the above time-based requirement and the achievement of a hurdle representing a 25% annual compound annual growth rate measured based on an initial value of $10.00 per share.

As of September 30, 2022, and December 31, 2021, there were 23,047,325 and 15,364,883 shares of the Company's Class A common stock authorized for issuance under the Incentive Plan, respectively. The number of shares authorized for issuance under the Incentive Plan will increase on January 1 of each year from 2022 to 2031 by the lesser of (i) 5% of the number of shares outstanding as of the close of business on the immediately preceding December 31 and (ii) the number of shares determined by the Company's board of directors. For the three months ended September 30, 2022, the Company granted 155,000 RSUs and recognized $2.7 million of stock compensation expense in relation to the incentive plan. For the nine months ended September 30, 2022, the Company granted 8,043,914 RSUs and recognized $6.7 million of stock-based compensation expense in relation to the Incentive Plan.

Employee Stock Purchase Plan

On December 9, 2021, we adopted the 2021 Employee Stock Purchase Plan ("ESPP"), which provides a means by which eligible employees may be given an opportunity to purchase shares of the Company’s Class A common stock. As of September 30, 2022, and December 31, 2021, there were 3,072,976 and 1,536,488 shares of the Company's Class A common stock authorized for issuance under the ESPP, respectively. The number of shares authorized for issuance under the ESPP will increase on January 1 of each year from 2022 to 2031 by the lesser of (i) 1% of the number of shares outstanding as of the close of business on the immediately preceding December 31 and (ii) the number of shares determined by the Company's board of directors. No shares of the Company’s Class A common stock were issued and no stock-based compensation expense was recognized in relation to the ESPP for the three and nine months ended September 30, 2022.

14.Income Taxes

The income tax provision for interim periods is determined using an estimate of the Company’s annual effective tax rate as adjusted for discrete items arising in that quarter.

For the three months ended September 30, 2022, and 2021, the Company had income tax expense of $2.0 million and income tax benefit of $2.6 million, respectively. For the nine months ended September 30, 2022, and 2021, the Company had income tax expense of $2.5 million and income tax benefit of $1.5 million, respectively. For the three and nine months ended September 30, 2022, the effective tax rate differs from the U.S. statutory rate primarily due to effects of non-deductible compensation, noncontrolling interests, redeemable noncontrolling interests, fair value adjustments for warrant liabilities and alignment shares, as well as state and local income taxes. For the three and nine months ended September 30, 2021, the effective tax rate differs from the U.S. statutory rate primarily due to effects of noncontrolling interests, redeemable noncontrolling interests, state and local income taxes, and gain on fair value remeasurement of contingent consideration.

15.Subsequent Events

The Company has evaluated subsequent events from September 30, 2022, through November 14, 2022, which is the date the unaudited condensed consolidated financial statements were available to be issued. Other than the subsequent event disclosed below and the warrant redemption completed on October 17, 2022, as further discussed in Note 7, "Fair Value Measurements," there are no subsequent events requiring recording or disclosure in the condensed consolidated financial statements.

Acquisition of DESRI II Acquisition Holdings, L.L.C. & DESRI V Acquisition Holdings, L.L.C.

On November 11, 2022, the Company acquired all of the outstanding membership interests in DESRI II Acquisition Holdings, L.L.C. and DESRI V Acquisition Holdings, L.L.C. (the "DESRI II & V Acquisition") from DESRI II, L.L.C. and DESRI V, L.L.C., respectively, under definitive Membership Interest Purchase Agreements that were announced on September 27, 2022. As a result of the DESRI II & V Acquisition, the Company acquired approximately 88 MW of operating solar facilities for total consideration at closing of approximately $102.0 million, including $82.0 million paid at closing and funded by cash on hand, and $20.0 million, payable within twelve to eighteen months, subject to customary hold back conditions.

The initial accounting for the DESRI II & V Acquisition, including the estimated fair value of the assets acquired and liabilities assumed, is incomplete as a result of the proximity of the acquisition date to the date these financial statements were issued.

Our historical operations and financial position may not be comparable to our operations and financial position as a result of our business combination with CBRE Acquisition Holdings, Inc. as described in Note 1, “General,” to our condensed consolidated financial statements included elsewhere in this Report (the "Merger"), recent acquisitions as described in Note 4, "Acquisitions and Disposals," to our condensed consolidated financial statements included elsewhere in this Report and Note 7, “Acquisitions,” to our audited consolidated annual financial statements included in our 2021 Annual Report on Form 10-K, and the cost becoming a public company.

As a public company, Altus is subject to additional rules and regulations applicable to companies listed on a national securities exchange and compliance and reporting obligations pursuant to the rules and regulations of the SEC. Altus expects to hire additional employees to meet these rules and obligations, and incur higher expenses for investor relations, accounting advisory, directors' and officers’ insurance, legal and other professional services and will engage consultants and third party advisors to assist with the heightened requirements of being a public company.

Key Factors Affecting Our Performance

Our results of operations and our ability to grow our business over time could be impacted by a number of factors and trends that affect our industry generally, as well as new offerings of services and products we may acquire or seek to acquire in the future. Additionally, our business is concentrated in certain markets, putting us at risk of region-specific disruptions such as adverse economic, regulatory, political, weather and other conditions. See “Risk Factors” in our 2021 Annual Report on Form 10-K and this Report for further discussion of risks affecting our business. We believe the factors discussed below are key to our success.

Execution of Growth Strategies

We believe we are in the beginning stages of a market opportunity driven by the broad shift away from traditional energy sources to renewable energy and an increasing emphasis by the C&I sector on their public commitment to decarbonization. We intend to leverage our competitive strengths and market position to become customers’ “one-stop-shop” for the clean energy transition by (i) using our existing customer and developer networks to build out our electric vehicle ("EV") charging and energy storage offerings and establish a position comparable to that of our C&I solar market position through our existing cross-sell opportunities and (ii) partnering with Blackstone and CBRE to access their client relationships, portfolio companies, and their strong brand recognition, to increase the number of customers we can support.

Competition

We compete in the C&I scale renewable energy space with utilities, developers, independent power producers, pension funds and private equity funds for new investment opportunities. We expect to grow our market share because of the following competitive strengths:

•Development Capability: We have established an innovative approach to the development process. From site identification and customer origination through the construction phase, we’ve established a streamlined process enabling us to further create the scalability of our platform and significantly reduce the costs and time in the development process. Part of our attractiveness to our customers is our ability to ensure a high level of execution certainty. We anticipate that this ability to originate, source, develop and finance projects will ensure we can continue to grow and meet the needs of our customers.

•Long-Term Revenue Contracts: Our C&I solar generation contracts have a typical length of 20 years or longer, creating long-term relationships with customers that allow us to cross-sell additional current and future products and services. The average remaining life of our current contracts is approximately 17 years. These long-term contracts are either structured at a fixed rate, often with an escalator, or floating rate pegged at a discount to the prevailing local utility rates. We refer to these latter contracts as variable rate, and as of September 30, 2022, these variable rate contracts make up approximately 56% of our current installed portfolio. During the nine months ended September 30, 2022, overall utility rates have been increasing in states where we have projects under variable rate contracts. The realization of solar power price increases varies depending on region, utility and terms of revenue contract, but generally, we would benefit from such increases in the future as inflationary pressures persist.

•Flexible Financing Solutions: We have a market-leading cost of capital in an investment-grade rated scalable credit facility from Blackstone, which enables us to be competitive bidders in asset acquisition and development. In addition to our Blackstone term loan, we also have financing available through a construction to term loan facility. This facility has $200 million of committed capacity which carries a floating rate of LIBOR plus 2.25%.

28

•Leadership: We have a strong executive leadership team who has extensive experience in capital markets, solar development and solar construction, with over 20 years of experience each. Moreover, through the transaction structure, management and employees will continue to own a significant interest in the Company.

•CBRE Partnership: Our partnership with CBRE, the largest global real estate services company, provides us with a clear path to creating new customer relationships. CBRE is the largest manager of data centers and 90% of the Fortune 100 are CBRE clients, providing a significant opportunity for us to expand our customer base.

Financing Availability

Our future growth depends in significant part on our ability to raise capital from third-party investors and lenders on competitive terms to help finance the origination of our solar energy systems. We have historically used a variety of structures including tax equity financing, construction loan financing, and term loan financing to help fund our operations. From September 4, 2013, the inception of Legacy Altus, to September 30, 2022, we have raised over $100 million of tax equity financing, $80 million in construction loan financing and $690 million of term loan financing. Our ability to raise capital from third-party investors and lenders is also affected by general economic conditions, the state of the capital markets, inflation levels, interest rate levels, and lenders' concerns about our industry or business.

Cost of Solar Energy Systems

Although the solar panel market has seen an increase in supply in the past few years, most recently, there has been upward pressure on prices due to lingering issues of the COVID-19 pandemic (further discussed below), recent inflationary pressures, growth in the solar industry, regulatory policy changes, tariffs and duties (including investigations of potential circumvention of antidumping and countervailing (AD/CV) duties and bans against imports of solar panel materials tied to forced labor), and an increase in demand. As a result of these developments, we have been experiencing higher prices on imported solar modules. The prices of imported solar modules have increased as a result of the COVID-19 pandemic and these other factors. If there are substantial increases, it may become less economical for us to serve certain markets. Attachment rates for energy storage systems have trended higher while the price to acquire has trended downward making the addition of energy storage systems a potential area of growth for us.

Seasonality

The amount of electricity our solar energy systems produce is dependent in part on the amount of sunlight, or irradiation, where the assets are located. Because shorter daylight hours in winter months and poor weather conditions due to rain or snow results in less irradiation, the output of solar energy systems will vary depending on the season and the overall weather conditions in a year. While we expect seasonal variability to occur, the geographic diversity in our assets helps to mitigate our aggregate seasonal variability.

Another aspect of seasonality to consider is in our construction program, which is more productive during warmer weather months and generally results in project completion during fourth quarter. This is particularly relevant for our projects under construction in colder climates like the Northeast.

Pipeline

As of September 30, 2022, our pipeline of opportunities totaled over one gigawatt and is comprised of approximately 50% potential operating acquisitions and 50% projects under development. The operating acquisitions are dynamic with new opportunities being evaluated by our team each quarter.

As of September 30, 2022, with respect to the half of our pipeline made up of development projects, approximately 24% of these projects are currently in construction or pre-construction, 43% of these projects are still in the contracting or due diligence phase, and the final 33% represent projects from our client engagements which are progressing toward an agreement in principle.

As of September 30, 2022, with respect to the half of our pipeline made up of potential operating acquisitions, approximately 17% of these projects are currently in the initial engagement phase, 30% of these projects are in negotiation, and the final 53% of these projects are in the closing phase.

Projects originated by our channel partners which we then develop, engineer and construct benefit from a shorter time from agreed terms to revenues, typically 6 to 9 months based on our historical experience. Projects that we are originating ourselves and self-developing, such as those with a lead from CBRE or Blackstone, would historically take 12 to 15 months from agreed

29

terms to bring to commercial operation. Given the supply chain challenges and permitting and interconnection delays described above, as of September 30, 2022, these historical timelines are currently pushed out by approximately 3 to 6 months.

On November 11, 2022, the Company acquired all of the outstanding membership interests in DESRI II Acquisition Holdings, L.L.C. and DESRI V Acquisition Holdings, L.L.C. (the "DESRI II & V Acquisition") from DESRI II, L.L.C. and DESRI V, L.L.C., respectively, under definitive Membership Interest Purchase Agreements that were announced on September 27, 2022. As a result of the DESRI II & V Acquisition, the Company acquired approximately 88 MW of operating solar facilities for total consideration at closing of approximately $102.0 million, including $82.0 million paid at closing and funded by cash on hand, and $20.0 million, payable within twelve to eighteen months, subject to customary hold back conditions.

Warrant Redemption

On September 15, 2022, the Company issued a notice for redemption of all 14,798,981 of the Company's outstanding Redeemable Warrants at 5:00 p.m. New York City time on October 17, 2022 (the “Redemption Date”) for a redemption price of $0.10 per Warrant (the “Redemption Price”). Holders could elect to exercise their Warrants on a “cashless basis” and surrender the Redeemable Warrants for that number of shares of Class A Common Stock that is determined by reference to the table set forth in Section 6.2 of the Warrant Agreement based on the Redemption Date and the Redemption Fair Market Value of $10.98. Given the Redemption Fair Market Value and the Redemption Date, the number of shares of Class A Common Stock to be issued for each Redeemable Warrant that is exercised through a cashless exercise is 0.2763.

As of September 30, 2022, holders of 1,687 Redeemable Warrants exercised their Redeemable Warrants with the payment of cash and the Company received $18,557 of cash proceeds. Holders of 10,614,564 Redeemable Warrants exercised their Redeemable Warrants on a cashless basis in exchange for 2,932,779 shares of Class A Common Stock per Redeemable Warrants.

As of the Redemption Date, holders of 8,462 Redeemable Warrants exercised their Redeemable Warrants with the payment of cash and the Company received $93,082 of cash proceeds. Holders of 14,690,310 Redeemable Warrants exercised their Redeemable Warrants on a cashless basis in exchange for 4,058,845 shares of Class A Common Stock per Redeemable Warrant. A total of 100,209 Warrants remained unexercised as of the Redemption Date, and the Company redeemed those Warrants for an aggregate redemption price of $10,021.

Government Regulations, Policies and Incentives

Our growth strategy depends in significant part on government policies and incentives that promote and support solar energy and enhance the economic viability of distributed solar. These incentives come in various forms, including net metering, eligibility for accelerated depreciation such as modified accelerated cost recovery system, solar renewable energy credits (“SRECs”), tax abatements, rebate and renewable target incentive programs and tax credits, particularly the Section 48(a) investment tax credits ("ITC"). We are a party to a variety of agreements under which we may be obligated to indemnify the counterparty with respect to certain matters. Typically, these obligations arise in connection with contracts and tax equity partnership arrangements, under which we customarily agree to hold the other party harmless against losses arising from a breach of warranties, representations, and covenants related to such matters as title to assets sold, negligent acts, damage to property, validity of certain intellectual property rights, non-infringement of third-party rights, and certain tax matters including indemnification to customers and tax equity investors regarding Commercial ITCs. The sale of SRECs has constituted a significant portion of our revenue historically. A change in the value of SRECs or changes in other policies or a loss or reduction in such incentives could decrease the attractiveness of distributed solar to us and our customers in applicable markets, which could reduce our growth opportunities. Such a loss or reduction could also reduce our willingness to pursue certain customer acquisitions due to decreased revenue or income under our solar service agreements. Additionally, such a loss or reduction may also impact the terms of and availability of third-party financing. If any of these government regulations, policies or incentives are adversely amended, delayed, eliminated, reduced, retroactively changed or not extended beyond their current expiration dates or there is a negative impact from the recent federal law changes or proposals, our operating results and the demand for, and the economics of, distributed solar energy may decline, which could harm our business.

Impact of the COVID-19 Pandemic and Supply Chain Issues

In March 2020, the World Health Organization declared the outbreak of the novel coronavirus (“COVID-19”) a pandemic.

Our business operations have continued to function effectively during the pandemic. We are continuously evaluating the pandemic and are taking necessary steps to mitigate known risks. We will continue to adjust our actions and operations as appropriate in order to continue to provide safe and reliable service to our customers and communities while keeping our employees and contractors safe. Although we have been able to mitigate to a certain extent the impact to the operations of the

30

Company to date, given that COVID-19 infections remain persistent in many states where we do business and the situation is evolving, we cannot predict the future impact of COVID-19 on our business. We considered the impact of COVID-19 on the use of estimates and assumptions used for financial reporting and noted there were material impacts on our results of operations for the nine months ended September 30, 2022, and 2021, as supply chain issues and logistical delays have materially impacted the timing of our construction schedules and likely will continue to have a material adverse effect on our business, financial condition, results of operations, and cash flows.

The service and installation of solar energy systems has continued during the COVID-19 pandemic. This continuation of service reflects solar services’ designation as an essential service in all of our service territories. Throughout the COVID-19 pandemic, we have seen some impacts to our supply chain affecting the timing of delivery of certain equipment, including, but not limited to, solar modules, inverters, racking systems, and transformers. Although we have been able to ultimately procure the equipment needed to service and install solar energy systems, we have experienced delays in such procurement. We have established a geographically diverse group of suppliers, which is intended to ensure that our customers have access to affordable and effective solar energy and storage options despite potential trade, geopolitical or event-driven risks. We do anticipate continuing impacts to our ability to source parts for our solar energy systems or energy storage systems, which we are endeavoring to mitigate via advanced planning and ordering from our diverse network of suppliers. However, if supply chains become even further disrupted due to additional outbreaks of the COVID-19 virus or more stringent health and safety guidelines are implemented, our ability to install and service solar energy systems could become more adversely impacted.

Governmental restrictions implemented to try to slow the spread of the COVID-19 virus have caused, and may continue to cause, us to experience operational delays and may cause milestones or deadlines relating to various project documents to be missed. To date, we have not received notices from our dealers regarding significant performance delays resulting from the COVID-19 pandemic. However, worsening economic conditions could result in such outcomes over time, which would impact our future financial performance. Further, the effects of the economic downturn associated with the COVID-19 pandemic may reduce consumer credit ratings and credit availability, which may adversely affect new customer origination and our existing customers’ ability to make payments on their solar service agreements. Periods of a lack of availability of credit may lead to increased delinquency and default rates. We have not experienced a significant increase in default or delinquency rates to date. However, if existing economic conditions continue for a prolonged period of time or worsen, delinquencies on solar service agreements could materialize, which would also negatively impact our future financial performance.

We cannot predict the full impact the COVID-19 pandemic or the significant disruption and volatility currently being experienced in the capital markets will have on our business, cash flows, liquidity, financial condition and results of operations at this time due to numerous uncertainties. The ultimate impact will depend on future developments, including, among other things, the ultimate duration of the COVID-19 virus, the distribution, acceptance and efficacy of the vaccine, the depth and duration of the economic downturn and other economic effects of the COVID-19 pandemic, the consequences of governmental and other measures designed to prevent the spread of the COVID-19 virus, actions taken by governmental authorities, customers, suppliers, dealers and other third parties, our ability and the ability of our customers, potential customers and dealers to adapt to operating in a changed environment and the timing and extent to which normal economic and operating conditions resume. For additional discussion regarding risks associated with the COVID-19 pandemic, see “Risk Factors” elsewhere in our 2021 Annual Report on Form 10-K.

Key Financial and Operational Metrics

We regularly review a number of metrics, including the following key operational and financial metrics, to evaluate our business, measure our performance and liquidity, identify trends affecting our business, formulate our financial projections and make strategic decisions.

Megawatts Installed

Megawatts installed represents the aggregate megawatt nameplate capacity of solar energy systems for which panels, inverters, and mounting and racking hardware have been installed on premises in the period. Cumulative megawatts installed represents the aggregate megawatt nameplate capacity of solar energy systems for which panels, inverters, and mounting and racking hardware have been installed on premises.

Non-GAAP Financial Measures

Adjusted EBITDA

We define adjusted EBITDA as net income plus net interest expense, depreciation, amortization and accretion expense, income tax expense, acquisition and entity formation costs, non-cash compensation expense, and excluding the effect of certain non-recurring items we do not consider to be indicative of our ongoing operating performance such as, but not limited to, gain or loss on fair value remeasurement of contingent consideration, change in fair value of redeemable warrant liability, change in fair value of alignment shares liability, and other miscellaneous items of other income and expenses.

We define adjusted EBITDA margin as adjusted EBITDA divided by operating revenues.

32

Adjusted EBITDA and adjusted EBITDA margin are non-GAAP financial measures that we use to measure our performance. We believe that investors and analysts also use adjusted EBITDA in evaluating our operating performance. This measurement is not recognized in accordance with U.S. GAAP and should not be viewed as an alternative to U.S. GAAP measures of performance. The U.S. GAAP measure most directly comparable to adjusted EBITDA is net income and to adjusted EBITDA margin is net income over operating revenues. The presentation of adjusted EBITDA and adjusted EBITDA margin should not be construed to suggest that our future results will be unaffected by non-cash or non-recurring items. In addition, our calculation of adjusted EBITDA and adjusted EBITDA margin are not necessarily comparable to adjusted EBITDA as calculated by other companies and investors and analysts should read carefully the components of our calculations of these non-GAAP financial measures.

We believe adjusted EBITDA is useful to management, investors and analysts in providing a measure of core financial performance adjusted to allow for comparisons of results of operations across reporting periods on a consistent basis. These adjustments are intended to exclude items that are not indicative of the ongoing operating performance of the business. Adjusted EBITDA is also used by our management for internal planning purposes, including our consolidated operating budget, and by our board of directors in setting performance-based compensation targets. Adjusted EBITDA should not be considered an alternative to but viewed in conjunction with U.S. GAAP results, as we believe it provides a more complete understanding of ongoing business performance and trends than U.S. GAAP measures alone. Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as reported under U.S. GAAP.

Components of Results of Operations

The Company derives its operating revenues principally from power purchase agreements, net metering credit agreements, solar renewable energy credits, and performance-based incentives. Approximately 56% of our combined power

33

purchase agreements and net metering credit agreements are variable-rate contracts, 17% are fixed-rate contracts with escalators, and 27% are fixed-rate contracts.

Revenue under PPAs. A portion of the Company’s power sales revenues is earned through the sale of energy (based on kilowatt hours) pursuant to the terms of PPAs. The Company’s PPAs typically have fixed or floating rates and are generally invoiced monthly. The Company applied the practical expedient allowing the Company to recognize revenue in the amount that the Company has a right to invoice which is equal to the volume of energy delivered multiplied by the applicable contract rate. As of September 30, 2022, PPAs have a weighted-average remaining life of 14 years.

Revenue from net metering credit agreements. A portion of the Company’s power sales revenues are obtained through the sale of net metering credits under net metering credit agreements (“NMCAs”). Net metering credits are awarded to the Company by the local utility based on kilowatt hour generation by solar energy facilities, and the amount of each credit is determined by the utility’s applicable tariff. The Company currently receives net metering credits from various utilities including Eversource Energy, National Grid Plc, and Xcel Energy. There are no direct costs associated with net metering credits, and therefore, they do not receive an allocation of costs upon generation. Once awarded, these credits are then sold to third party offtakers pursuant to the terms of the offtaker agreements. The Company views each net metering credit in these arrangements as a distinct performance obligation satisfied at a point in time. Generally, the customer obtains control of net metering credits at the point in time when the utility assigns the generated credits to the Company account, who directs the utility to allocate to the customer based upon a schedule. The transfer of credits by the Company to the customer can be up to one month after the underlying power is generated. As a result, revenue related to NMCA is recognized upon delivery of net metering credits by the Company to the customer. As of September 30, 2022, NMCAs have a weighted-average remaining life of 18 years.

SREC revenue. The Company applies for and receives SRECs in certain jurisdictions for power generated by solar energy systems it owns. The quantity of SRECs is based on the amount of energy produced by the Company’s qualifying generation facilities. SRECs are sold pursuant to agreements with third parties, who typically require SRECs to comply with state-imposed renewable portfolio standards. Holders of SRECs may benefit from registering the credits in their name to comply with these state-imposed requirements, or from selling SRECs to a party that requires additional SRECs to meet its compliance obligations. The Company receives SRECs from various state regulators including New Jersey Board of Public Utilities, Massachusetts Department of Energy Resources, and Maryland Public Service Commission. There are no direct costs associated with SRECs and therefore, they do not receive an allocation of costs upon generation. The majority of individual SREC sales reflect a fixed quantity and fixed price structure over a specified term. The Company typically sells SRECs to different customers from those purchasing the energy under PPAs. The Company believes the sale of each SREC is a distinct performance obligation satisfied at a point in time and that the performance obligation related to each SREC is satisfied when each SREC is delivered to the customer.

Rental income. A portion of the Company’s energy revenue is derived from long-term PPAs accounted for as operating leases under Accounting Standards Codification ("ASC") 840, Leases. Rental income under these lease agreements is recorded as revenue when the electricity is delivered to the customer.

Performance-Based Incentives. Many state governments, utilities, municipal utilities and co-operative utilities offer a rebate or other cash incentive for the installation and operation of a renewable energy facility. Up-front rebates provide funds based on the cost, size or expected production of a renewable energy facility. Performance-based incentives provide cash payments to a system owner based on the energy generated by its renewable energy facility during a pre-determined period, and they are paid over that time period. The Company recognizes revenue from state and utility incentives at the point in time in which they are earned.

Other Revenue. Other revenue consists primarily of sales of power on wholesale electricity market which are recognized in revenue upon delivery.

Cost of Operations (Exclusive of Depreciation and Amortization). Cost of operations primarily consists of operations and maintenance expense, site lease expense, insurance premiums, property taxes and other miscellaneous costs associated with the operations of solar energy facilities. Altus expects its cost of operations to continue to grow in conjunction with its business growth. These costs as a percentage of revenue will decrease over time, offsetting efficiencies and economies of scale with inflationary increases of certain costs.

General and Administrative. General and administrative expenses consist primarily of salaries, bonuses, benefits and all other employee-related costs, including stock-based compensation, professional fees related to legal, accounting, human resources, finance and training, information technology and software services, marketing and communications, travel and rent and other office-related expenses.

34

Altus expects increased general and administrative expenses as it continues to grow its business but to decrease over time as a percentage of revenue. Altus also expects to incur additional expenses as a result of operating as a public company, including expenses necessary to comply with the rules and regulations applicable to companies listed on a national securities exchange and related to compliance and reporting obligations pursuant to the rules and regulations of the SEC. Further, Altus expects to incur higher expenses for investor relations, accounting advisory, directors' and officers' insurance, and other professional services.

Depreciation, Amortization and Accretion Expense. Depreciation expense represents depreciation on solar energy systems that have been placed in service. Depreciation expense is computed using the straight-line composite method over the estimated useful lives of assets. Leasehold improvements are depreciated over the shorter of the estimated useful lives or the remaining term of the lease. Amortization includes third party costs necessary to enter into site lease agreements, third party costs necessary to acquire PPA and NMCA customers and favorable and unfavorable rate revenues contracts. Third party costs necessary to enter into site lease agreements are amortized using the straight-line method ratably over 15-30 years based upon the term of the individual site leases. Third party costs necessary to acquire PPAs and NMCA customers are amortized using the straight-line method ratably over 15-25 years based upon the term of the customer contract. Estimated fair value allocated to the favorable and unfavorable rate PPAs and REC agreements are amortized using the straight-line method over the remaining non-cancelable terms of the respective agreements. Accretion expense includes over time increase of asset retirement obligations associated with solar energy facilities.

Acquisition and Entity Formation Costs. Acquisition and entity formation costs represent costs incurred to acquire businesses and form new legal entities. Such costs primarily consist of professional fees for banking, legal, accounting and appraisal services.

Fair Value Remeasurement of Contingent Consideration. In connection with the Solar Acquisition (as defined in Note 7, “Fair Value Measurements,” to our condensed consolidated financial statements included elsewhere in this Report), contingent consideration of up to an aggregate of $10.5 million may be payable upon achieving certain market power rates and actual power volumes generated by the acquired solar energy facilities. The Company estimated the fair value of the contingent consideration for future earnout payments using a Monte Carlo simulation model. Significant assumptions used in the measurement include the estimated volumes of power generation of acquired solar energy facilities during the 18-36-month period since the acquisition date, market power rates during the 36-month period, and the risk-adjusted discount rate associated with the business.

Gain on Disposal of Property, Plant and Equipment. In connection with the disposal of land, the Company recognized a gain on disposal of property, plant and equipment, which represents the excess of consideration received over the carrying value of the disposed land.

Stock-Based Compensation. Stock-based compensation expense is recognized for awards granted under the Legacy Incentive Plans and Omnibus Incentive Plan, as defined in Note 13, "Stock-Based Compensation," to our condensed consolidated financial statements included elsewhere in this Report.

Change in Fair Value of Redeemable Warrant Liability. In connection with the Merger, the Company assumed a redeemable warrant liability composed of publicly listed warrants (the "Redeemable Warrants") and warrants issued to CBRE Acquisition Sponsor, LLC in the private placement (the "Private Placement Warrants"). Redeemable Warrant Liability was remeasured as of September 30, 2022, and the resulting loss was included in the condensed consolidated statements of operations. As our Redeemable Warrants (other than the Private Placement Warrants) continued to trade separately as of September 30, 2022, on the NYSE following the Merger, the Company determines the fair value of the Redeemable Warrants based on the quoted trading price of those warrants. The Private Placement Warrants have the same redemption and make-whole provisions as the Redeemable Warrants. Therefore, the fair value of the Private Placement Warrants is equal to the Redeemable Warrants. The Company determines the fair value of the Redeemable Warrants, including Private Placement Warrants, based on the quoted trading price of the Redeemable Warrants.

Change in Fair Value of Alignment Shares Liability. Alignment shares represent Class B common stock of the Company which were issued in connection with the Merger. Class B common stock, par value $0.0001 per share ("Alignment Shares") are accounted for as liability-classified derivatives, which were remeasured as of September 30, 2022, and the resulting loss was included in the condensed consolidated statements of operations. The Company estimates the fair value of outstanding Alignment Shares using a Monte Carlo simulation valuation model utilizing a distribution of potential outcomes based on a set of underlying assumptions such as stock price, volatility, and risk-free interest rates.

Other (Income) Expense, Net. Other income and expenses primarily represent state grants and other miscellaneous items.

35

Interest Expense, Net. Interest expense, net represents interest on our borrowings under our various debt facilities, amortization of debt discounts and deferred financing costs, and unrealized gains and losses on interest rate swaps.

Loss on Extinguishment of Debt. Loss on extinguishment of debt represents the premium paid on early redemption related to the redemption of a portion of the Rated Term Loan (as defined in Note 6, "Debt,” to our condensed consolidated financial statements included elsewhere in this Report) and the write off of the unamortized deferred financing costs.

Income Tax (Expense) Benefit. We account for income taxes under ASC 740, Income Taxes. As such, we determine deferred tax assets and liabilities based on temporary differences resulting from the different treatment of items for tax and financial reporting purposes. We measure deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to reverse. Additionally, we must assess the likelihood that deferred tax assets will be recovered as deductions from future taxable income. We have a partial valuation allowance on our deferred state tax assets because we believe it is more likely than not that a portion of our deferred state tax assets will not be realized. We evaluate the recoverability of our deferred tax assets on a quarterly basis.

Net Income (Loss) Attributable to Noncontrolling Interests and Redeemable Noncontrolling Interests. Net income attributable to noncontrolling interests and redeemable noncontrolling interests represents third-party interests in the net income or loss of certain consolidated subsidiaries based on Hypothetical Liquidation at Book Value.

Income tax (expense) benefit	$	(1,964)	$	2,552	$	(4,516)	(177.0)	%

For the three months ended September 30, 2022, the Company recorded an income tax expense of $2.0 million in relation to pretax loss of $94.7 million, which resulted in an effective income tax rate of negative 2.1%. The effective income tax rate was primarily impacted by $21.8 million of income tax expense related to fair value adjustments on redeemable warrants and alignment shares, $0.3 million of income tax benefit associated with nondeductible compensation, and $0.4 million of state income tax expense.

Related to the $21.8 million of income tax expense, the Company has issued redeemable warrants and alignment shares. These awards are liability classified awards, and, as such, they are required to be remeasured to fair value each reporting period with the change in value included in operating income. The redeemable warrants and alignment shares are considered equity awards for U.S. tax purposes. Therefore, the change in value does not result in taxable income or deduction. The change in fair value results in a permanent tax difference which impacts the Company’s estimated annual effective tax rate.

For the three months ended September 30, 2021, the Company recorded an income tax benefit of $2.6 million in relation to a pretax loss of $3.8 million, which resulted in an effective income tax rate of 66.1%. The effective income tax rate was primarily impacted by $0.7 million of income tax benefit due to net losses attributable to noncontrolling interests and redeemable noncontrolling interests, $0.4 million of state income tax benefit, and $0.7 million of income tax benefit associated with the remeasurement of contingent consideration.

The loss was primarily driven by the increase in the Company's stock price as of September 30, 2022, compared to December 31, 2021.

Loss on extinguishment of debt recognized by the Company during the nine months ended September 30, 2021, was associated with the Rated Term Loan that the Company refinanced on August 25, 2021. In conjunction with the refinancing, a portion of the Amended Rated Term Loan was extinguished, resulting in a loss on extinguishment of debt of $3.2 million.

Income tax (expense) benefit	$	(2,548)	$	1,497	$	(4,045)	(270.2)	%

For the nine months ended September 30, 2022, the Company recorded an income tax expense of $2.5 million in relation to pretax loss of $12.4 million, which resulted in an effective income tax rate of negative 20.6%. The effective income tax rate was primarily impacted by $2.7 million of income tax expense related to fair value adjustments on redeemable warrants and alignment shares, $1.1 million of income tax expense associated with nondeductible compensation, $0.6 million of income tax expense from net losses attributable to noncontrolling interests and redeemable noncontrolling interests, and $0.5 million of state income tax expense.

Related to the $2.7 million of income tax expense, the Company has issued redeemable warrants and alignment shares. These awards are liability classified awards, and, as such, they are required to be remeasured to fair value each reporting period with the change in value included in operating income. The redeemable warrants and alignment shares are considered equity awards for U.S. tax purposes. Therefore, the change in value does not result in taxable income or deduction. The change in fair value results in a permanent tax difference which impacts the Company’s estimated annual effective tax rate.

For the nine months ended September 30, 2021, the Company recorded an income tax benefit of $1.5 million in relation to a pretax loss of $3.0 million, which resulted in an effective income tax rate of 50.6%. The effective income tax rate was primarily impacted by $0.2 million of income tax benefit due to net losses attributable to noncontrolling interests and redeemable noncontrolling interests, $0.2 million of state income tax benefit, and $0.5 million of income tax benefit associated with the remeasurement of contingent consideration.

Net loss attributable to noncontrolling interests and redeemable noncontrolling interests	$	(2,473)	$	(186)	$	(2,287)	1229.6	%

Net loss attributable to redeemable noncontrolling interests and noncontrolling interests was $2.5 million during the nine months ended September 30, 2022, as compared to $0.2 million for the nine months ended September 30, 2021, primarily due to additional funding provided by a tax equity investor and reduced recapture periods for investment tax credits.

Liquidity and Capital Resources

As of September 30, 2022, the Company had total cash and restricted cash of $297.4 million. For a discussion of our restricted cash, see Note 2, “Significant Accounting Policies, Cash, Cash Equivalents, and Restricted Cash,” to our condensed consolidated financial statements.

We seek to maintain diversified and cost-effective funding sources to finance and maintain our operations, fund capital expenditures, including customer acquisitions, and satisfy obligations arising from our indebtedness. Historically, our primary sources of liquidity included proceeds from the issuance of redeemable preferred stock, borrowings under our debt facilities, third party tax equity investors and cash from operations. Additionally, the Company received cash proceeds of $293 million as a result of the Merger. Our business model requires substantial outside financing arrangements to grow the business and facilitate the deployment of additional solar energy facilities. We will seek to raise additional required capital from borrowings under our existing debt facilities, third party tax equity investors and cash from operations.

The solar energy systems that are in service are expected to generate a positive return rate over the useful life, typically 32 years. Typically, once solar energy systems commence operations, they do not require significant additional capital expenditures to maintain operating performance. However, in order to grow, we are currently dependent on financing from outside parties. The Company will have sufficient cash and cash flows from operations to meet working capital, debt service obligations, contingencies and anticipated required capital expenditures for at least the next 12 months. However, we are subject to business and operational risks that could adversely affect our ability to raise additional financing. If financing is not available to us on acceptable terms if and when needed, we may be unable to finance installation of our new customers’ solar energy systems in a manner consistent with our past performance, our cost of capital could increase, or we may be required to significantly reduce the scope of our operations, any of which would have a material adverse effect on our business, financial condition, results of operations and prospects. In addition, our tax equity funds and debt instruments impose restrictions on our ability to draw on financing commitments. If we are unable to satisfy such conditions, we may incur penalties for non-performance under certain tax equity funds, experience installation delays, or be unable to make installations in accordance with our plans or at all. Any of these factors could also impact customer satisfaction, our business, operating results, prospects and financial condition.

Contractual Obligations and Commitments

We enter into service agreements in the normal course of business. These contracts do not contain any minimum purchase commitments. Certain agreements provide for termination rights subject to termination fees or wind down costs. Under such agreements, we are contractually obligated to make certain payments to vendors, mainly, to reimburse them for their unrecoverable outlays incurred prior to cancellation. The exact amounts of such obligations are dependent on the timing of termination, and the exact terms of the relevant agreement and cannot be reasonably estimated. As of September 30, 2022, we do not expect to cancel these agreements.

The Company has operating leases for land and buildings and has contractual commitments to make payments in accordance with site lease agreements.

Off-Balance Sheet Arrangements

The Company enters into letters of credit and surety bond arrangements with lenders, local municipalities, government agencies, and land lessors. These arrangements relate to certain performance-related obligations and serve as security under the applicable agreements. As of September 30, 2022, and December 31, 2021, the Company had outstanding letters of credit and surety bonds totaling $12.8 million and $10.6 million, respectively. Our outstanding letters of credit are primarily used to fund

48

the debt service reserve account associated with the Amended Rated Term Loan. We believe the Company will fulfill the obligations under the related arrangements and do not anticipate any material losses under these letters of credit or surety bonds.

Debt

Amended Rated Term Loan Facility

As part of the Blackstone Capital Facility, APA Finance, LLC (“APAF”), a wholly owned subsidiary of the Company, entered into a $251.0 million term loan facility with Blackstone Insurance Solutions ("BIS") through a consortium of lenders, which consists of investment grade-rated Class A and Class B notes (the "Rated Term Loan").

On August 25, 2021, APAF entered into an Amended and Restated Credit Agreement with BIS to refinance the Rated Term Loan (hereby referred to as the “Amended Rated Term Loan”). The Amended Rated Term Loan added an additional $135.6 million to the facility, bringing the aggregate facility to $503.0 million. The Amended Rated Term Loan has a weighted average 3.51% annual fixed rate, reduced from the previous weighted average rate of 3.70%, and matures on February 29, 2056 (“Final Maturity Date”).

The Amended Rated Term Loan amortizes at an initial rate of 2.5% of outstanding principal per annum for a period of 8 years at which point the amortization steps up to 4% per annum until September 30, 2031 (“Anticipated Repayment Date”). After the Anticipated Repayment Date, the loan becomes fully-amortizing, and all available cash is used to pay down principal until the Final Maturity Date.

As of September 30, 2022, the outstanding principal balance of the Rated Term Loan was $490.3 million less unamortized debt discount and loan issuance costs totaling $7.8 million. As of December 31, 2021, the outstanding principal balance of the Rated Term Loan was $500.0 million less unamortized debt discount and loan issuance costs totaling $8.4 million.

As of September 30, 2022, the Company was in compliance with all covenants. As of December 31, 2021, the Company was in compliance with all covenants, except the delivery of the APAF audited consolidated financial statements, for which the Company obtained a waiver to extend the financial statement reporting deliverable due date. The Company delivered the audited financial statements on May 25, 2022, before the extended reporting deliverable due date.

Construction Loan to Term Loan Facility

On January 10, 2020, APA Construction Finance, LLC (“APACF”) a wholly-owned subsidiary of the Company, entered into a credit agreement with Fifth Third Bank, National Association and Deutsche Bank AG New York Branch to fund the development and construction of future solar facilities (“Construction Loan to Term Loan Facility”). The Construction Loan to Term Loan Facility includes a construction loan commitment of $187.5 million and a letter of credit commitment of $12.5 million, which can be drawn until January 10, 2023.

The construction loan commitment can convert to a term loan upon commercial operation of a particular solar energy facility. In addition, the Construction Loan to Term Loan Facility accrued a commitment fee at a rate equal to 0.50% per year of the daily unused amount of the commitment. As of September 30, 2022, the outstanding principal balances of the construction loan and term loan were zero and $16.0 million, respectively. As of December 31, 2021, the outstanding principal balances of the construction loan and term loan were $5.6 million and $12.3 million, respectively. As of September 30, 2022, and December 31, 2021, the Company had an unused borrowing capacity of $171.5 million and $169.7 million, respectively. For the three months ended September 30, 2022, and 2021, the Company incurred interest costs associated with outstanding construction loans totaling zero and $0.1 million, respectively. For the nine months ended September 30, 2022, and 2021 the Company incurred interest costs associated with outstanding construction loans totaling zero and $0.4 million, respectively. These interest costs were capitalized as part of property, plant and equipment. Also, on October 23, 2020, the Company entered into an additional letters of credit facility with Fifth Third Bank for the total capacity of $10.0 million. The Construction Loan to Term Loan Facility includes various financial and other covenants for APACF and the Company, as guarantor. As of September 30, 2022, and December 31, 2021, the Company was in compliance with all covenants.

Project-Level Term Loan

In conjunction with the Stellar NJ 2 Acquisition, the Company assumed a project-level term loan with an outstanding principal balance of $14.1 million and a fair value discount of $2.2 million. The term loan is subject to scheduled semi-annual amortization and interest payments, and matures on September 1, 2029.

49

As of September 30, 2022, the outstanding principal balance of the term loan is $12.6 million, less unamortized debt discount of $2.2 million, which was recognized as part of the acquisition. During the nine months ended September 30, 2022, the Company incurred interest costs associated with the term loan of $0.2 million.

The term loan is secured by an interest in the underlying solar project assets and the revenues generated by those assets, as well as a letter of credit with Fifth Third Bank with a total capacity of $2.1 million. As of September 30, 2022, there were no amounts outstanding under the letter of credit. As of September 30, 2022, the Company was in compliance with all covenants.

Financing Lease Obligations

From time to time, the Company sells equipment to third parties and enters into master lease agreements to lease the equipment back for an agreed-upon term. Due to certain forms of continuous involvement provided by the master lease agreements, sale leaseback accounting is prohibited under ASC 840. Therefore, the Company accounts for these transactions using the financing method by recognizing the sale proceeds as a financing obligation and the assets subject to the sale-leaseback remain on the balance sheet of the Company and are being depreciated. The aggregate proceeds have been recorded as long-term debt within the condensed consolidated balance sheets.

As of September 30, 2022 and December 31, 2021, the Company's recorded financing obligations were $36.0 million, net of $1.1 million of deferred transaction costs. Payments of $0.9 million and $0.1 million were made under financing lease obligations for the three months ended September 30, 2022, and 2021, respectively. Payments of $1.5 million and $0.1 million were made under financing obligations for the nine months ended September 30, 2022 and 2021, respectively. Interest expense, inclusive of the amortization of deferred transaction costs, for the three months ended September 30, 2022, and 2021, was $0.4 million and $0.2 million, respectively. Interest expense, inclusive of the amortization of deferred transaction costs, for the nine months ended September 30, 2022 and 2021, was $1.1 million and $0.2 million, respectively.

Cash used for financing activities was partially offset by $3.2 million of contributions from noncontrolling interests.

Net cash used for financing activities was $196.2 million for the nine months ended September 30, 2021, which consisted primarily of $148.8 million to repay long-term debt, $17.7 million of paid dividends and commitment fees on Series A preferred stock, $4.3 million of deferred transaction costs, $1.9 million of distributions to noncontrolling interests, $2.2 million of debt issuance costs, and $0.1 million of paid contingent consideration. Cash used for financing activities was partially offset by $288.9 million of proceeds from issuance of long-term debt and $2.7 million of contributions from noncontrolling interests.

Critical Accounting Policies and Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our estimates, including those related to inventories, long-lived assets, goodwill, identifiable intangibles, contingent consideration liabilities and deferred income tax valuation allowances. We base our estimates on historical experience and on appropriate and customary assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Some of these accounting estimates and assumptions are particularly sensitive because of their significance to our consolidated financial statements and because of the possibility that future events affecting them may differ markedly from what had been assumed when the financial statements were prepared. As of September 30, 2022, there have been no significant changes to the accounting estimates that we have deemed critical. Our critical accounting estimates are more fully described in our 2021 Annual Report on Form 10-K.

Other than the policies noted in Note 2, “Significant Accounting Policies,” in the Company’s notes to the condensed consolidated financial statements in this Report, there have been no material changes to its critical accounting policies and estimates as compared to those disclosed in its audited consolidated financial statements in our 2021 Annual Report on Form 10-K.

Emerging Growth Company Status

In April 2012, the Jumpstart Our Business Startups Act of 2012, or the JOBS Act, was enacted. Section 107 of the JOBS Act provides that an “emerging growth company,” or an EGC, can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act of 1933, as amended, or the Securities Act, for complying with new or revised accounting standards. Thus, an EGC can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. Altus has elected to use the extended transition period for new or revised accounting standards during the period in which we remain an EGC.

We expect to remain an EGC until the earliest to occur of: (1) the last day of the fiscal year in which we, as applicable, have more than $1.235 billion in annual revenue; (2) the date we qualify as a “large accelerated filer,” with at least $700 million of equity securities held by non-affiliates; (3) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period; and (4) the last day of the fiscal year ending after the fifth anniversary of our initial public offering.

Additionally, we are a “smaller reporting company” as defined in Item 10(f)(1) of Regulation S-K. We will remain a smaller reporting company until the last day of the fiscal year in which (i) the market value of our stock held by non-affiliates is greater than or equal to $250 million as of the end of that fiscal year's second fiscal quarter, or (ii) our annual revenues are greater than or equal to $100 million during the most recently completed fiscal year and the market value of our stock held by non-affiliates is greater than or equal to $700 million as of the end of that fiscal year's second fiscal quarter. If we are a smaller reporting company at the time we cease to be an emerging growth company, we may continue to rely on exemptions from certain disclosure requirements that are available to smaller reporting companies. Specifically, as a smaller reporting company we may choose to present only the two most recent fiscal years of audited financial statements in our Annual Report on Form

51

10-K and, similar to emerging growth companies, smaller reporting companies have reduced disclosure obligations regarding executive compensation.

Recent Accounting Pronouncements

A description of recently issued accounting pronouncements that may potentially impact our financial position and results of operations is disclosed in Note 2 to our condensed consolidated financial statements appearing elsewhere in this Report.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to various market risks in our normal business activities. Market risk is the potential loss that may result from market changes associated with our business or with an existing or forecasted financial or commodity transactions.

Interest Rate Risk

A significant portion of our outstanding debt has a fixed interest rate (for further details refer to Note 6, "Debt," to our condensed consolidated financial statements included elsewhere in this Report). However, changes in interest rates create a modest risk because certain borrowings bear interest at floating rates based on LIBOR plus a specified margin. We sometimes manage our interest rate exposure on floating-rate debt by entering into derivative instruments to hedge all or a portion of our interest rate exposure on certain debt facilities. We do not enter into any derivative instruments for trading or speculative purposes. Changes in economic conditions could result in higher interest rates, thereby increasing our interest expense and operating expenses and reducing funds available for capital investments, operations, and other purposes. A hypothetical 10% increase in our interest rates on our variable debt facilities would not have a material impact on the value of the Company’s cash, cash equivalents, debt, net income, or cash flows.

Credit Risk

Financial instruments which potentially subject Altus to significant concentrations of credit risk consist principally of cash and restricted cash. Our investment policy requires cash and restricted cash to be placed with high-quality financial institutions and limits the amount of credit risk from any one issuer. We additionally perform ongoing credit evaluations of our customers’ financial condition whenever deemed necessary and generally do not require collateral.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our Co-Chief Executive Officers and Chief Financial Officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q, as such term is defined in Rules 13a‐15(e) and 15d‐15(e) under the Securities and Exchange Act, as amended (the “Exchange Act”).

Disclosure controls and procedures are designed to ensure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Co-Chief Executive Officers and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Based on this evaluation of our disclosure controls and procedures, our management, including our Co-Chief Executive Officers and Chief Financial Officer, have concluded that our disclosure controls and procedures were not effective as of September 30, 2022, because of the material weaknesses in our internal control over financial reporting that were disclosed in our 2021 Annual Report on Form 10-K.

Remediation Plan

As previously described in Part II, Item 9A of our 2021 Annual Report on Form 10-K, with the oversight of senior management and our audit committee, we are taking the steps below and plan to take additional measures to remediate the underlying causes of the material weaknesses:

•We have proceeded with steps intended to remediate the insufficient qualified personnel material weakness, including hiring additional finance department employees with appropriate expertise, including a Technical Accounting Manager, Accounts Payable Manager, and Tax Director;

52

•We have hired a SOX Manager who specializes in internal controls and organizational risk assessment, identification of control activities, controls documentation and the enhancement of ongoing monitoring activities related to the internal controls over financial reporting to address the lack of a formalized risk assessment process; and

•We have proceeded with steps intended to remediate the selection and development of the control activities material weakness through the documentation of processes and controls in the financial statement close, reporting and disclosure processes while working to deploy a new enterprise resource planning system designed to improve the accuracy and controls over financial reporting. The new system enhancements and activities are designed to enable us to broaden the scope and quality of our internal reviews of information supporting financial reporting and to formalize and enhance our internal control procedures.

We cannot assure you that the measures we have taken to date, and are continuing to implement, will be sufficient to remediate the material weaknesses we have identified or avoid potential future material weaknesses.

Changes in Internal Control over Financial Reporting

As discussed above, we implemented certain measures to remediate the material weaknesses identified in the design and operation of our internal control over financial reporting. In addition, during the nine months ended September 30, 2022, we have completed the implementation of an accounting system, which enables a more efficient financial statements closing process. Other than those measures, there have been no changes in our internal control over financial reporting during the nine months ended September 30, 2022, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

53

Part II - Other Information

Item 1. Legal Proceedings

From time to time, the Company is a party to a number of claims and governmental proceedings which are ordinary, routine matters incidental to its business. In addition, in the ordinary course of business the Company periodically has disputes with vendors and customers. All current pending matters are not expected to have, either individually or in the aggregate, a material adverse effect on the Company’s financial position or results of operations.

Item 1A. Risk Factors

This Report supplements the risk factors set forth in Part I, Item 1A. of the 2021 Annual Report on Form 10-K with the following risk factors, which update, and should be read in conjunction with, the risk factors set forth therein.

Summary of Risk Factors

•If we cannot compete successfully against other solar and energy companies, we may not be successful in developing our operations and our business may suffer;

•With respect to providing electricity on a price-competitive basis, solar systems face competition from traditional regulated electric utilities, less-regulated third party energy service providers and new renewable energy companies;

•A material reduction in the retail price of traditional utility-generated electricity or electricity from other sources could harm our business, financial condition, results of operations and prospects;

•Due to the limited number of suppliers in our industry, the acquisition of any of these suppliers by a competitor or any shortage, delay, quality issue, price change or other limitations in our ability to obtain components or technologies we use could result in adverse effects;

•Although our business has benefited from the declining cost of solar panels in the past, our financial results may be harmed now that the cost of solar panels has increased, and our costs overall may continue to increase in the future due to increases in the cost of solar panels and tariffs on imported solar panels imposed by the U.S. government;

•Our market is characterized by rapid technological change, which requires us to continue to develop new products and product innovations. Any delays in such development could adversely affect market adoption of our products and our financial results;

•Developments in alternative technologies may materially adversely affect demand for our offerings;

•The operation and maintenance of our facilities are subject to many operational risks, the consequences of which could have a material adverse effect on our business, financial condition, results of operations and prospects;

•Our business, financial condition, results of operations and prospects could suffer if we do not proceed with projects under development or are unable to complete the construction of, or capital improvements to, facilities on schedule or within budget;

•We face risks related to project siting, financing, construction, permitting, governmental approvals and the negotiation of project development agreements that may impede their development and operating activities; and

•While our growth strategy includes seeking acquisitions of operating solar power generation assets and portfolios, we may not be successful in identifying or making any acquisitions in the future. We may not realize the anticipated benefits of acquisitions, and integration of these acquisitions may disrupt our business and management.

Risks Related to our Business

We may not be able to effectively manage our growth.

Our future growth may cause a significant strain on our management and our operational, financial, and other resources. Our ability to manage our growth effectively will require us to implement and improve our operational, financial, and management systems and to expand, train, manage, and motivate our employees and develop processes to efficiently integrate our strategic acquisition of portfolio assets, which is a primary part of our future growth strategy. These demands will require the hiring of additional management personnel and the development of additional expertise by management. Any increase in resources used without a corresponding increase in our operational, financial, and management systems could have a negative impact on our business, financial condition, and results of operations.

54

While our growth strategy includes seeking acquisitions of operating solar power generation assets and portfolios, we may not be successful in identifying or making any acquisitions in the future. We may not realize the anticipated benefits of acquisitions, and integration of these acquisitions may disrupt our business and management.

Our business strategy includes growth through the acquisitions of solar power generation assets and portfolios. We may not be able to continue to identify attractive acquisition opportunities or successfully acquire those opportunities that are identified in our pipeline. There is always the possibility that even if there is success in integrating our current or future acquisitions into the existing operations, we may not derive the benefits, such as administrative or operational synergies or earnings obtained, that were expected from such acquisitions, which may result in the commitment of capital resources without the expected returns on the capital. The competition for acquisition opportunities may increase which in turn would increase our cost of making further acquisitions or causing us to curb our activities of making additional acquisitions.

In pursuing our business strategy, from time to time we evaluate targets and enter into agreements regarding possible acquisitions, divestitures, and joint ventures. To be successful, we conduct due diligence to identify valuation issues and potential loss contingencies, negotiate transaction terms, complete transactions, and manage post-closing matters such as the integration of acquired assets and businesses. Our due diligence reviews are subject to the completeness and accuracy of disclosures made by third parties. We may incur unanticipated costs or expenses following a completed acquisition, including post-closing asset impairment charges, expenses associated with eliminating duplicate facilities, litigation, and other liabilities.

We have in the past, and in the future we may, acquire companies, project pipelines, products or technologies or enter into joint ventures or other strategic initiatives. We may not realize the anticipated benefits of these acquisitions, and any acquisition has numerous risks. These risks include the following:

•difficulty in assimilating the operations and personnel of the acquired company;

•difficulty in effectively integrating the acquired technologies or products with our current technologies;

•difficulty in maintaining controls, procedures and policies during the transition and integration;

•disruption of our ongoing business and distraction of our management and employees from other opportunities and challenges due to integration issues;

•difficulty integrating the acquired company’s accounting, management information, and other administrative systems;

•inability to retain key technical and managerial personnel of the acquired business;

•inability to retain key customers, vendors, and other business partners of the acquired business;

•inability to achieve the financial and strategic goals for the acquired and combined businesses;

•incurring acquisition-related costs or amortization costs for acquired intangible assets that could impact our operating results;

•potential failure of the due diligence processes to identify significant issues with product quality, intellectual property infringement, and other legal and financial liabilities, among other things;

•misjudging the value of acquired assets to us;

•potential inability to assert that internal controls over financial reporting are effective; and

•potential inability to obtain, or obtain in a timely manner, approvals from governmental authorities, which could delay or prevent such acquisitions.

Acquisitions of companies, businesses and assets are inherently risky and, if we do not complete the integration of these acquisitions successfully and in a timely manner, we may not realize the anticipated benefits of the acquisitions to the extent anticipated, which could adversely affect our business, financial condition, or results of operations. In addition, our guidance and estimates for our future operating and financials results assume the completion of certain of our acquisitions that are in our acquisition pipeline. If we are unable to execute on our actionable pipeline and integrate these acquisitions, we may miss our guidance, which could adversely affect the market price of our Class A Common Stock and our business, financial condition, or results of operations.

Our acquisition of solar project portfolios may not be as successful as acquiring the assets individually.

We may acquire entire portfolios of solar projects and the performance of individual solar projects in such a portfolio will vary. We may not derive the benefits, such as administrative or operational synergies that were expected and our earnings from the entire portfolio may not exceed the earnings we would have received had we purchased some, but not all, of the solar projects contained in such portfolio.

If we are unable to retain and recruit qualified technicians and advisors, or if our directors, key executives, key employees or consultants discontinue their employment or consulting relationship with us, it may delay our development efforts or otherwise harm our business.

55

We may not be able to attract or retain qualified management or technical personnel in the future due to the intense competition for qualified personnel among solar, energy, and other businesses. Our industry has experienced a high rate of turnover of management personnel in recent years. If we are not able to attract, retain, and motivate necessary personnel to accomplish our business objectives, we may experience constraints that will significantly impede the successful development of any product candidates, our ability to raise additional capital, and our ability to implement our overall business strategy.

We are highly dependent on members of our management and technical staff. Our success also depends on our ability to continue to attract, retain and motivate highly skilled junior, mid-level, and senior managers as well as junior, mid-level, and senior technical personnel. The loss of any of our executive officers, key employees, or consultants and our inability to find suitable replacements could potentially harm our business, financial condition, and prospects. We may be unable to attract and retain personnel on acceptable terms given the competition among solar and energy companies. Certain of our current officers, directors, and/or consultants hereafter appointed may from time to time serve as officers, directors, scientific advisors, and/or consultants of other solar and energy companies. We do not maintain “key man” insurance policies on any of our officers or employees. Other than certain members of our senior management team, all of our employees are employed “at will” and, therefore, each employee may leave our employment and join a competitor at any time.

We plan to grant stock options, restricted stock grants, restricted stock unit grants, or other forms of equity awards in the future as a method of attracting and retaining employees, motivating performance, and aligning the interests of employees with those of our shareholders. If we are unable to implement and maintain equity compensation arrangements that provide sufficient incentives, we may be unable to retain our existing employees and attract additional qualified candidates. If we are unable to retain our existing employees and attract additional qualified candidates, our business and results of operations could be adversely affected. Currently the exercise prices of all outstanding stock options are greater than the current stock price.

As of September 22, 2022, we had 61 full-time employees and no part-time employees. We may be unable to implement and maintain an attractive incentive compensation structure in order to attract and retain the right talent. These actions could lead to disruptions in our business, reduced employee morale and productivity, increased attrition, and problems with retaining existing and recruiting future employees.

Our business, financial condition, results of operations and prospects can be materially adversely affected by weather conditions, including, but not limited to, the impact of severe weather.

Weather conditions directly influence the demand for electricity and natural gas and other fuels and affect the price of energy and energy-related commodities. In addition, severe weather and natural disasters, such as hurricanes, floods, tornadoes, icing events and earthquakes, can be destructive and cause power outages and property damage, reduce revenue, affect the availability of fuel and water, and require us to incur additional costs, for example, to restore service and repair damaged facilities, to obtain replacement power and to access available financing sources. Furthermore, our physical plants could be placed at greater risk of damage should changes in the global climate produce unusual variations in temperature and weather patterns, resulting in more intense, frequent and extreme weather events, and abnormal levels of precipitation. A disruption or failure of electric generation, or storage systems in the event of a hurricane, tornado or other severe weather event, or otherwise, could prevent us from operating our business in the normal course and could result in any of the adverse consequences described above. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.

Where cost recovery is available, recovery of costs to restore service and repair damaged facilities is or may be subject to regulatory approval, and any determination by the regulator not to permit timely and full recovery of the costs incurred could have a material adverse effect on our business, financial condition, results of operations and prospects. Changes in weather can also affect the production of electricity at power generation facilities.

Our results of operations may fluctuate from quarter to quarter, which could make our future performance difficult to predict and could cause our results of operations for a particular period to fall below expectations, resulting in a decline in the price of our common stock.

Our quarterly results of operations are difficult to predict and may fluctuate significantly in the future. We have experienced seasonal and quarterly fluctuations in the past and expect these fluctuations to continue. However, given that we are operating in a rapidly changing industry and one of our primary growth strategies is to acquire strategic portfolio assets, those fluctuations may be masked by our recent growth rates. As a result, these fluctuations may not be readily apparent from our historical results of operations and our past quarterly results of operations may not be good indicators of likely future performance. In addition to the other risks described in this “Risk factors” section, as well as the factors discussed in the 2021 Annual Report on Form 10-K, the following factors, among others, could cause our results of operations and key performance indicators to fluctuate:

•the expiration, reduction or initiation of any governmental tax rebates, tax exemptions, or incentive;

56

•significant fluctuations in customer demand for our solar service offerings or fluctuations in the geographic concentration of installations of solar energy systems;

•changes in financial markets, which could restrict our ability to access available and cost-effective financing sources;

•seasonal, environmental or weather conditions that impact sales, energy production, and system installation;

•the acquisition of portfolio assets or other companies that we would expect to be able to integrate into our business operations and the costs associated therewith, including the costs of diligence and integration;

•the amount and timing of operating expenses related to the maintenance and expansion of our business, operations and infrastructure;

•announcements by us or our competitors of new products or services, significant acquisitions, strategic partnerships or joint ventures;

•capital-raising activities or commitments;

•changes in our pricing policies or terms or those of our competitors, including utilities;

•changes in regulatory policy related to solar energy generation;

•the loss of one or more key partners or the failure of key partners to perform as anticipated;

•our failure to successfully integrate acquired solar facilities;

•actual or anticipated developments in our competitors’ businesses or the competitive landscape;

•actual or anticipated changes in our growth rate;

•general economic, industry and market conditions, including as a result of the COVID-19 pandemic; and

•changes to our cancellation rate.

In the past, we have experienced seasonal fluctuations in installations in certain states, particularly in the fourth quarter. This has been the result of weather-related installation delays. Our actual revenue or key operating metrics in one or more future quarters may fall short of the expectations of investors and financial analysts. If that occurs, the market price of our common stock could decline and stockholders could lose part or all of their investment.

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

As of December 31, 2021, we had U.S. federal and state net operating loss carryforwards (“NOLs”) of approximately $177.4 million and $87.7 million, respectively, which begin expiring in varying amounts in 2034 and 2022, respectively, if unused. Under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (the “Code”), if a corporation undergoes an “ownership change,” the corporation’s ability to use its pre-change NOLs and other pre-change tax assets, such as tax credits, to offset its post-change income and taxes may be limited. In general, an “ownership change” occurs if there is a cumulative change in our ownership by “5% shareholders’ that exceeds 50 percentage points over a rolling three-year period. Similar rules may apply under state tax laws.

Additionally, states may impose other limitations on the use of NOLs and tax credit carryforwards. For example, California has recently imposed other limitations on the use of NOLs and limited the use of certain tax credits for taxable years beginning in 2020 through 2022.

Our ability to use our NOLs may be limited by an applicable ownership change. Any such limitations on our ability to use our NOLs and other tax assets could adversely impact our business, financial condition, and results of operations. Any limitation may result in the expiration of all or a portion of the net operating loss carryforwards and tax credit carryforwards before utilization.

As an emerging growth company and smaller reporting company within the meaning of the Securities Act, we will utilize certain modified disclosure requirements, and we cannot be certain if these reduced requirements will make our common stock less attractive to investors.

We are an “emerging growth company” within the meaning of the Securities Act of 1933, as amended (the “Securities Act”), and for as long as we continue to be an emerging growth company, we may choose to take advantage of exemptions from various reporting requirements that are available to “emerging growth companies,” but not to other public companies, including:

•not being required to have our independent registered public accounting firm audit our internal control over financial reporting under Section 404 of the Sarbanes-Oxley Act of 2002, as amended the (“Sarbanes-Oxley Act”);

•reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements; and

•exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved.

57

We plan in filings with the U.S. Securities and Exchange Commission (“SEC”) to continue to utilize the modified disclosure requirements available to emerging growth companies. As a result, our stockholders may not have access to certain information they may deem important. We could remain an “emerging growth company” until the earliest of:

•December 31, 2026;

•the last day of the first fiscal year in which our annual gross revenue exceeds $1.235 billion;

•the date that we become a “large accelerated filer” as defined in Rule 12b-2 under the Exchange Act, which would occur if the market value of our common stock that is held by non-affiliates exceeds $700 million as of the last business day of our most recently completed second fiscal quarter; and

•the date on which we have issued more than $1.0 billion in non-convertible debt during the preceding three-year period.

Additionally, we are a “smaller reporting company” as defined in Item 10(f)(1) of Regulation S-K. Smaller reporting companies may take advantage of certain reduced disclosure obligations, including, among other things, providing only two years of financial statements. We will remain a smaller reporting company until the last day of the fiscal year in which (i) the market value of our common stock held by non-affiliates is greater than or equal to $250 million as of the end of that fiscal year’s second fiscal quarter, and (ii) our annual revenues are greater than or equal to $100 million during the last completed fiscal year and the market value of our common stock held by non-affiliates is greater than or equal to $700 million as of the end of that fiscal year’s second fiscal quarter. To the extent we take advantage of such reduced disclosure obligations, it may also make comparison of our financial statements with other public companies difficult or impossible.

We have identified material weaknesses in our internal control over financial reporting. If we are unable to remediate these material weaknesses, or otherwise fail to maintain an effective system of internal control over financial reporting, this may result in material misstatements of our consolidated financial statements or cause us to fail to meet our periodic reporting obligations.

As a privately-held company, we were not required to evaluate our internal control over financial reporting in a manner that meets the standards of publicly traded companies required by Section 404(a) of the Sarbanes-Oxley Act. As a public company, we are required, pursuant to Section 404(a) of the Sarbanes-Oxley Act, to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting in our annual report for the year ended December 31, 2021 and subsequent quarterly reports on Form 10-Q. This assessment includes disclosure of any material weaknesses identified by our management in our internal control over financial reporting.

A material weakness is a deficiency or combination of deficiencies in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the financial statements would not be prevented or detected on a timely basis.

We have identified material weaknesses in our internal control over financial reporting that we are currently working to remediate, which relate to: (a) insufficient qualified personnel, which caused management to be unable to appropriately define responsibilities to create an effective control environment; (b) the lack of a formalized risk assessment process; and (c) selection and development of control activities, including over information technology.

Our management has concluded that these material weaknesses in our internal control over financial reporting are due to the fact that prior to the Merger we were a private company with limited resources and did not have the necessary business processes and related internal controls formally designed and implemented coupled with the appropriate resources with the appropriate level of experience and technical expertise to oversee our business processes and controls.

Our management has developed a remediation plan which we have begun and will continue to implement. These remediation measures are ongoing and include: hiring additional accounting and financial reporting personnel and implementing additional policies, procedures and controls. The material weaknesses will be considered remediated when our management designs and implements effective controls that operate for a sufficient period of time and management has concluded, through testing, that these controls are effective. Our management will monitor the effectiveness of its remediation plans and will make changes management determines to be appropriate, however we may encounter problems or delays in completing the remediation of the material weaknesses. In connection with the material weaknesses identified in our internal control over financial reporting we determined that our internal control over financial reporting are not effective and were not effective as of December 31, 2021, March 31, 2022, June 30, 2022, and September 30, 2022.

If not remediated, these material weaknesses could result in material misstatements to our annual or interim consolidated financial statements that might not be prevented or detected on a timely basis, or in delayed filing of required periodic reports. If we are unable to assert that our internal control over financial reporting is effective, or when required in the future, if our

58

independent registered public accounting firm is unable to express an unqualified opinion as to the effectiveness of the internal control over financial reporting, investors may lose confidence in the accuracy and completeness of our financial reports, the market price of our common stock could be adversely affected and our company could become subject to litigation or investigations by the NYSE, SEC, or other regulatory authorities, which could require additional financial and management resources. Each of these material weaknesses could result in a misstatement of account balances or disclosures that would result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected.

In order to maintain and improve the effectiveness of its internal control over financial reporting, we have expended, and anticipate that we will continue to expend, significant resources, including accounting-related costs and significant management oversight. Our independent registered public accounting firm is not required to formally attest to the effectiveness of our internal control over financial reporting until after we are no longer an emerging growth company. At such time, our independent registered public accounting firm may issue a report that is adverse in the event it is not satisfied with the level at which our internal control over financial reporting is documented, designed or operating. Any failure to maintain effective disclosure controls and internal control over financial reporting, and remediate identified material weaknesses could adversely affect our business and operating results and could cause a decline in the market price of our common stock.

The rules governing the standards that must be met for our management to assess our internal control over financial reporting are complex and require significant documentation, testing and possible remediation. Testing and maintaining internal controls may divert our management’s attention from other matters that are important to our business. Our testing, or the subsequent testing by our independent registered public accounting firm, may reveal additional deficiencies in our internal controls over financial reporting that are deemed to be material weaknesses. A material weakness in internal controls could result in our failure to detect a material misstatement of our annual or quarterly consolidated financial statements or disclosures. We may not be able to conclude on an ongoing basis that we have effective internal controls over financial reporting in accordance with Section 404. If we are unable to conclude that we have effective internal controls over financial reporting, investors could lose confidence in our reported financial information, which could have a material adverse effect on the market price of our common stock.

Our historical financial results may not be indicative of what our actual financial position or results of operations would have been if we were a public company.

Our business has achieved rapid growth since we launched. Our net revenue was $71.8 million and $45.3 million for the years ended December 31, 2021 and 2020, respectively, and $74.4 million and $50.2 million for the nine months ended September 30, 2022 and 2021, respectively. Our net income (loss) was $13.0 million and $(1.9) million for the years ended December 31, 2021 and 2020, respectively, and $(15.4) million and $(1.5) million for the nine months ended September 30, 2022 and 2021, respectively. However, our results of operations, financial condition and cash flows reflected in our consolidated financial statements may not be indicative of the results we would have achieved if we were a public company or results that may be achieved in future periods. Consequently, there can be no assurance that we will be able to generate sufficient income to pay our operating expenses and make satisfactory distributions to our shareholders, or any distributions at all.

Any reductions or modifications to, or the elimination of, governmental incentives or policies that support solar energy, including, but not limited to, tax laws, policies and incentives, renewable portfolio standards or feed-in-tariffs, or the imposition of additional taxes or other assessments on solar energy, could result in, among other items, the lack of a satisfactory market for the development and/or financing of new solar energy projects, our abandoning the development of solar energy projects, a loss of our investments in solar energy projects and reduced project returns, any of which could have a material adverse effect on our business, financial condition, results of operations and prospects.

We depend heavily on government policies that support utility scale renewable energy and enhance the economic feasibility of developing and operating solar energy projects in regions in which we operate or plan to develop and operate renewable energy facilities. The federal government and a majority of state governments in the United States provide incentives, such as tax incentives, renewable portfolio standards or feed-in-tariffs, that support or are designed to support the sale of energy from utility scale renewable energy facilities, such as wind and solar energy facilities. As a result of budgetary constraints, political factors or otherwise, governments from time to time may review their laws and policies that support renewable energy and consider actions that would make the laws and policies less conducive to the development and operation of renewable energy facilities. Any reductions or modifications to, or the elimination of, governmental incentives or policies that support renewable energy or the imposition of additional taxes or other assessments on renewable energy, could result in, among other items, the lack of a satisfactory market for the development and/or financing of new renewable energy projects, our abandoning the development of renewable energy projects, a loss of our investments in the projects and reduced project returns, any of which could have a material adverse effect on our business, financial condition, results of operations and prospects.

59

On August 16, 2022, President Biden signed into law the Inflation Reduction Act (the “IRA”), which extends the availability of investment tax credits (“ITCs”) and production tax credits (“PTCs”). We and our tax equity partners have claimed and expect to continue to claim ITCs with respect to qualifying solar energy projects. In structuring tax equity partnerships and determining ITC eligibility, we have relied upon applicable tax law and published Internal Revenue Service (“IRS”) guidance. However, the application of law and guidance regarding ITC eligibility to the facts of particular solar energy projects is subject to a number of uncertainties, in particular with respect to the new IRA provisions for which Department of Treasury regulations (“Treasury Regulations”) are forthcoming, and there can be no assurance that the IRS will agree with our approach in the event of an audit. The Department of Treasury is expected to issue Treasury Regulations and additional guidance with respect to the application of the newly enacted IRA provisions, and the IRS and Department of Treasury may modify existing guidance, possibly with retroactive effect. Any of the foregoing items could reduce the amount of ITCs or, if applicable, PTCs available to us and our tax equity partners. In this event, we could be required to indemnify tax equity partners for disallowed ITCs or, if applicable, PTCs, adjust the terms of future tax equity partnerships, or seek alternative sources of funding for solar energy projects, each of which could have a material adverse effect on our business, financial condition, results of operations and prospects.

The absence of net energy metering and related policies to offer competitive pricing to our customers in our current markets, and adverse changes to net energy metering policies, may significantly reduce demand for electricity from our solar energy systems.

Each of the states where we currently serve customers has adopted a net energy metering policy. Net energy metering typically allows our customers to interconnect their on-site solar energy systems to the utility grid and offset their utility electricity purchases by receiving a bill credit at the utility’s retail rate for energy generated by their solar energy system that is exported to the grid in excess of the electric load used by the customers. At the end of the billing period, the customer simply pays for the net energy used or receives a credit at the retail rate if more energy is produced than consumed. Utilities operating in states without a net energy metering policy may receive solar electricity that is exported to the grid when there is no simultaneous energy demand by the customer without providing retail compensation to the customer for this generation. In addition to net metering policies, certain of our primary markets, including Massachusetts, New Jersey and Maryland have adopted programs specifically aimed at providing renewable energy benefits to specific customers, such as community solar and low and moderate income customers. Many of these programs are set-up with a finite capacity of MW installed. Historically, regulators in our primary markets have continuously rolled out new incentive programs as the caps on existing programs begin to fill to promote continued investment in renewables in order to meet the goals set forth in their renewable portfolio standards, however the continuous roll-out of such programs is not guaranteed.

Our ability to sell solar energy systems and the electricity they generate may be adversely impacted by the failure to expand existing limits on the amount of net energy metering in states that have implemented it, the failure to adopt a net energy metering policy where it currently is not in place, the imposition of new charges that only or disproportionately impact customers that utilize net energy metering, or reductions in the amount or value of credit that customers receive through net energy metering. If such charges are imposed, the cost savings associated with switching to solar energy may be significantly reduced and our ability to attract future customers and compete with traditional utility providers could be impacted. Our ability to sell solar energy systems and the electricity they generate also may be adversely impacted by the unavailability of expedited or simplified interconnection for grid-tied solar energy systems or any limitation on the number of customer interconnections or amount of solar energy that utilities are required to allow in their service territory or some part of the grid.

Limits on net energy metering, interconnection of solar energy systems and other operational policies in key markets could limit the number of solar energy systems installed in those markets. If the caps on net energy metering in jurisdictions are reached, and new caps are not put in place, or if the amount or value of credit that customers receive for net energy metering is significantly reduced, future customers will be unable to recognize the current cost savings associated with net energy metering. We rely substantially on net energy metering when we establish competitive pricing for our prospective customers and the absence of net energy metering for new customers would greatly limit demand for our solar energy systems.

Our Redeemable Warrants (including the Private Placement Warrants) and alignment shares have been accounted for as derivative liabilities and have been recorded at fair value with changes in fair value each period reported in earnings, which may have an adverse effect on the market price of our common stock.

CBRE Acquisition Holdings, Inc. (“CBAH”) sold 10,062,500 Redeemable Warrants as part of the Shareholder Aligned Initial Listing (“SAILSM”) securities in the initial public offering of CBAH (which traded separately on the NYSE under the symbol “CBAH WS” prior to the Closing and following the Closing trade under the symbol “AMPS WS”). The Redeemable Warrants are exercisable for an aggregate of 10,062,500 shares of Class A Common Stock at a purchase price of $11.00 per share. CBAH also issued 7,366,667 warrants to CBRE Acquisition Sponsor, LLC (the “Sponsor”) in a private placement simultaneously with the closing of CBAH’s initial public offering and 2,000,000 warrants to the Sponsor in full settlement of a second amended and

60

restated promissory note with the Sponsor (such warrants, the “Private Placement Warrants”). The Private Placement Warrants are exercisable for an aggregate of 9,366,667 shares of our Class A Common Stock at a purchase price of $11.00 per share.

We have 1,207,500 alignment shares outstanding, all of which are held by the Sponsor, certain officers of CBAH (such officers, together with the Sponsor, the “Sponsor Parties”) and existing CBAH directors. The Alignment Shares will automatically convert into shares of Class A Common Stock based upon the Total Return (as defined below in “Description of securities”) on the Class A Common Stock as of the relevant measurement date over each of the seven fiscal years following the Merger.

We account for the Redeemable Warrants and alignment shares as derivative liabilities, which are presented at fair value each reporting period, with changes in fair value recorded through earnings. As the Redeemable Warrants (other than our Private Placement Warrants) trade separately on the NYSE, the fair value of the Redeemable Warrants will be determined based on the quoted trading price of those warrants. The Private Placement Warrants have the same redemption and make-whole provisions as the Redeemable Warrants. Therefore, the fair value of the Private Placement Warrants is equal to the Redeemable Warrants. The fair value of the Private Placement Warrants is determined based on the quoted trading price of the Redeemable Warrants.

We estimate the fair value of our alignment share using a Monte Carlo simulation, which is based on various market inputs (e.g., measurement of our stock price after the consummation of the Merger).

As a result of the estimation processes involved in presenting these instruments at fair value, our financial statements and results of operations may fluctuate quarterly, based on various factors, many of which are outside of our control. If our stock price is volatile, we expect that we will recognize non-cash gains or losses on our Redeemable Warrants (including Private Placement Warrants) and alignment shares for each reporting period and that the amount of such gains or losses could be material. The impact of changes in fair value on earnings may have an adverse effect on the market price of our Class A Common Stock.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

On May 31, 2022, June 15, 2022, and August 17, 2022, and the Company entered into separate, privately negotiated warrant exchange agreements (the "Exchange Agreements") with a limited number of holders of the Company's outstanding Redeemable Warrants. Pursuant to the Exchange Agreements, the Company agreed to issue an aggregate of 1,111,243 shares of Class A common stock to the holders of Redeemable Warrants in exchange for the surrender and cancellation of an aggregate of 4,630,163 Redeemable Warrants. The issuance by the Company of the shares of Common Stock in exchange for the surrender and cancellation of the Redeemable Warrants was made in reliance on the exemption from registration in Section 3(a)(9) of the Securities Act. Immediately prior to the exchange, the Redeemable Warrants were remeasured to fair value based on the trading price of the exchanged shares of common stock, resulting in a gain on fair value remeasurement of $4.1 million within operating income in the condensed consolidated statements of operations for the nine months ended September 30, 2022, and a redeemable warrant liability of $7.8 million, which was then reclassified to additional paid-in capital in the condensed consolidated balance sheet as of September 30, 2022.

Company Overview

Altus Power, Inc., a Delaware corporation (the “Company” or "Altus"), headquartered in Stamford, Connecticut, develops, owns, constructs and operates large-scale roof, ground and carport-based photovoltaic solar energy generation and storage systems, for the purpose of producing and selling electricity to credit worthy counterparties, including commercial and industrial, public sector and community solar customers, under long-term contracts. The Solar energy facilities are owned by the Company in project specific limited liability companies (the “Solar Facility Subsidiaries”).

On December 9, 2021 (the "Closing Date"), CBRE Acquisition Holdings, Inc. ("CBAH"), a special purpose acquisition company, consummated the business combination pursuant to the terms of the business combination agreement entered into on July 12, 2021 (the "Business Combination Agreement"), whereby, among other things, CBAH Merger Sub I, Inc. ("First Merger Sub") merged with and into Altus Power, Inc. (f/k/a Altus Power America, Inc.) ("Legacy Altus") with Legacy Altus continuing as the surviving corporation, and immediately thereafter Legacy Altus merged with and into CBAH Merger Sub II, Inc. ("Second Merger Sub") with Second Merger Sub continuing as the surviving entity and as a wholly owned subsidiary of CBAH (together with the merger with the First Merger Sub, the “Merger”). In connection with the closing of the Merger, CBAH changed its name to "Altus Power, Inc." and CBAH Merger Sub II (after merger with Legacy Altus) changed its name to "Altus Power, LLC."

COVID-19

The spike of a novel strain of coronavirus (“COVID-19”) in the first quarter of 2020 caused significant volatility in the U.S. markets that remains ongoing. In response to the COVID-19 pandemic, federal, state, local, and foreign governments put in place, and in the future may again put in place, travel restrictions, quarantines, “stay at home” orders and guidelines, and similar government orders and restrictions, in an attempt to control the spread of the disease. Such restrictions or orders resulted in, and in the future may result in, business closures, work stoppages, slowdowns and delays, among other effects that negatively impacted, and in the future may negatively impact, our operations, as well as the operations of our customers and business partners. In addition, COVID-19 has caused disruptions to the supply chain across the global economy, including within the solar industry, and we are working with our equipment suppliers to minimize disruptions to our operations. Certain suppliers have experienced, and may continue to experience, delays and increased costs related to a variety of factors, including logistical delays and component shortages from upstream vendors. Based on the challenges described above, such as supply chain and logistical delays, such results have had and will continue to have a material adverse effect on our business, operations, financial condition, results of operations, and cash flows.

Accounting Policies [Abstract]

Significant Accounting Policies

Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The Company prepares its unaudited condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and regulations of the U.S. Securities and Exchange Commission ("SEC") for interim financial reporting. The Company’s condensed consolidated financial statements include the results of wholly-owned and partially-owned subsidiaries in which the Company has a controlling interest. All intercompany balances and transactions have been eliminated in consolidation.

Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2021 filed with the Company’s 2021 annual report on Form 10-K on March 24, 2022, and the related notes which provide a more complete discussion of the Company’s accounting policies and certain other information. The information as of December 31, 2021, included in the condensed consolidated balance sheets was derived from the Company’s audited consolidated financial statements. The condensed consolidated financial statements were prepared on the same basis as the audited consolidated financial statements and reflect all adjustments, including normal recurring adjustments, which are, in the opinion of management, necessary for a fair statement of the Company’s financial position as of September 30, 2022, and the results of operations and cash flows for the three and nine months ended September 30, 2022, and

2021. The results of operations for the three and nine months ended September 30, 2022, are not necessarily indicative of the results that may be expected for the full year or any other future interim or annual period.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates.

In recording transactions and balances resulting from business operations, the Company uses estimates based on the best information available. Estimates are used for such items as the fair value of net assets acquired in connection with accounting for business combinations, the useful lives of the solar energy facilities, and inputs and assumptions used in the valuation of asset retirement obligations (“AROs”), contingent consideration, and alignment shares.

Segment Information

Operating segments are defined as components of a company about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company’s chief operating decision makers are the co-chief executive officers. Based on the financial information presented to and reviewed by the chief operating decision makers in deciding how to allocate the resources and in assessing the performance of the Company, the Company has determined it operates as a single operating segment and has one reportable segment, which includes revenue under power purchase agreements, revenue from net metering credit agreements, solar renewable energy certificate revenue, rental income, performance-based incentives, and other revenue. The Company’s principal operations, revenue and decision-making functions are located in the United States.

Cash, Cash Equivalents, and Restricted Cash

Cash and cash equivalents includes all cash balances on deposit with financial institutions and readily marketable securities with original maturity dates of three months or less at the time of acquisition that are denominated in U.S. dollars. Pursuant to the budgeting process, the Company maintains certain cash and cash equivalents on hand for possible equipment replacement related costs.

The Company records cash that is restricted as to withdrawal or use under the terms of certain contractual agreements as restricted cash. Restricted cash is included in current portion of restricted cash and restricted cash, noncurrent portion on the condensed consolidated balance sheets and includes cash held with financial institutions for cash collateralized letters of credit pursuant to various financing and construction agreements.

The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the condensed consolidated balance sheets. Cash, cash equivalents, and restricted cash consist of the following:

	As of September 30, 2022		As of December 31, 2021
Cash and cash equivalents	$	290,894	$	325,983
Current portion of restricted cash	2,477		2,544
Restricted cash, noncurrent portion	4,018		1,794
Total	$	297,389	$	330,321

Concentration of Credit Risk

The Company maintains its cash in bank deposit accounts which, at times, may exceed Federal Deposit Insurance Corporation insurance limits. The Company has not experienced any losses in such accounts and believes it is not exposed to any significant credit risk on cash balances.

The Company had one customer that individually accounted for 31.5% of total accounts receivable as of September 30, 2022. The Company had one customer that individually accounted for 19.8% of total revenue for the three months ended

September 30, 2022. The Company had one customer that individually accounted for 13.8% of total revenue for the nine months ended September 30, 2022.

The Company had two customers that individually accounted for 16.0% and 11.7% of total accounts receivable as of December 31, 2021. The Company had one customer that individually accounted for 11.7% of total revenue for the three months ended September 30, 2021. The Company had no customers that individually accounted for over 10% of total revenue for the nine months ended September 30, 2021.

Accounting Pronouncements

As a public company, the Company is provided the option to adopt new or revised accounting guidance as an “emerging growth company” under the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) either (1) within the same periods as those otherwise applicable to public business entities, or (2) within the same time periods as non-public business entities, including early adoption when permissible. The Company expects to elect to adopt new or revised accounting guidance within the same time period as non-public business entities, as indicated below.

Recent Accounting Pronouncements Adopted

In December 2019, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2019-12, Income Taxes (Topic 740), which simplifies the accounting for income taxes, primarily by eliminating certain exceptions to ASC 740. This standard is effective for fiscal periods beginning after December 15, 2020. The Company has adopted this standard as of the first quarter of 2021 and did not have a material impact on the condensed consolidated financial statements.

Recent Accounting Pronouncements Not Yet Adopted

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which primarily changes the lessee’s accounting for operating leases by requiring recognition of lease right-of-use assets and lease liabilities. This standard is effective for annual reporting periods beginning after December 15, 2021. The Company expects to adopt this guidance in fiscal year 2022. The Company is continuing the analysis of the contractual arrangements that may qualify as leases under the new standard and expects the most significant impact will be the recognition of the right-of-use assets and lease liabilities on the consolidated balance sheets.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and has since released various amendments including ASU No. 2019-04. The new standard generally applies to financial assets and requires those assets to be reported at the amount expected to be realized. The ASU is effective for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact of this guidance on its consolidated financial statements.

Stellar NJ Acquisition

On April 1, 2022, the Company acquired a 1.0 MW solar energy facility located in New Jersey (the "Stellar NJ Acquisition") from a third party for a total purchase price of $1.3 million. The transaction was accounted for as an acquisition of assets, whereby the Company acquired $2.3 million of property, plant and equipment and assumed $0.4 million of intangible liabilities and $0.6 million of other liabilities. The intangible liability assumed is associated with an unfavorable rate power purchase agreement and has a weighted average amortization period of 15 years.

On June 10, 2022, the Company acquired a 4.6 MW portfolio of six solar energy facilities located in Hawaii (the "Stellar HI 2 Acquisition") from a third party for a total purchase price of $9.9 million, including $0.2 million of transaction related costs. This transaction was accounted for as an acquisition of assets, whereby the Company acquired $7.3 million of property, plant and equipment and $3.1 million of intangible assets, and assumed $0.5 million of intangible liabilities and $0.1 million of asset retirement obligations.

The Company attributed intangible asset and liability values to favorable and unfavorable rate revenue contracts to sell power generated by the acquired solar energy facilities, as well as a favorable rate lease. The following table summarizes the estimated fair values and the weighted average amortization periods of the acquired intangible assets and assumed intangible liabilities as of the acquisition date:

	Fair Value (thousands)		Weighted Average Amortization Period

Variable Interest Entity

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Variable Interest Entity

Variable Interest Entity

The Company consolidates all variable interest entities (“VIEs”) in which it holds a variable interest and is deemed to be the primary beneficiary of the variable interest entity. Generally, a VIE is an entity with at least one of the following conditions: (a) the total equity investment at risk is insufficient to allow the entity to finance its activities without additional subordinated financial support, or (b) the holders of the equity investment at risk, as a group, lack the characteristics of having a controlling financial interest. The primary beneficiary of a VIE is required to consolidate the VIE and to disclose certain information about its significant variable interests in the VIE. The primary beneficiary of a VIE is the entity that has both 1) the power to direct the activities that most significantly impact the entity’s economic performance and 2) the obligations to absorb losses or receive benefits that could potentially be significant to the VIE.

The Company participates in certain partnership arrangements that qualify as VIEs. Consolidated VIEs consist of tax equity financing arrangements and partnerships in which an investor holds a noncontrolling interest and does not have substantive kick-out or participating rights. The Company, through its subsidiaries, is the primary beneficiary of such VIEs, because as the manager, it has the power to direct the day-to-day operating activities of the entity. In addition, the Company is exposed to economics that could potentially be significant to the entity given its ownership interest, and, therefore, has consolidated the VIEs as of September 30, 2022, and December 31, 2021. No VIEs were deconsolidated during the nine months ended September 30, 2022 and 2021.

The obligations of the consolidated VIEs discussed in the following paragraphs are nonrecourse to the Company. In certain instances where the Company establishes a new tax equity structure, the Company is required to provide liquidity in accordance with the contractual agreements. The Company has no requirement to provide liquidity to purchase assets or guarantee performance of the VIEs unless further noted in the following paragraphs. The Company made certain contributions during the nine months ended September 30, 2022 and 2021, as determined in the respective operating agreement.

The carrying amounts and classification of the consolidated VIE assets and liabilities included in condensed consolidated balance sheets are as follows:

	As of September 30, 2022		As of December 31, 2021
Current assets	$	17,356	$	13,131
Non-current assets	378,099		372,761
Total assets	$	395,455	$	385,892
Current liabilities	$	3,525	$	3,652
Non-current liabilities	40,821		40,978
Total liabilities	$	44,346	$	44,630

The amounts shown in the table above exclude intercompany balances which are eliminated upon consolidation. All of the assets in the table above are restricted for settlement of the VIE obligations, and all of the liabilities in the table above can only be settled using VIE resources.

The Company has not identified any VIEs during the nine months ended September 30, 2022 and 2021, for which the Company determined that it is not the primary beneficiary and thus did not consolidate.

The Company considered qualitative and quantitative factors in determining which VIEs are deemed significant. During each of the nine months ended September 30, 2022 and the year ended December 31, 2021, the Company consolidated twenty-six and twenty-five VIEs, respectively. No VIEs were deemed significant as of September 30, 2022 and December 31, 2021.

As discussed in Note 4, on August 29, 2022, the Company completed the Stellar NJ 2 Acquisition, including the acquisition of a controlling financial interest in a VIE which owns and operates a single 1.1 MW solar generating facility. The Company acquired a controlling financial interest by entering into an asset management agreement which provides the Company with the power to direct the operating activities of the VIE and the obligation to absorb losses or receive benefits that could potentially be significant to the VIE. The asset management agreement also includes a call and put option to acquire the equity interest in June 2023 and January 2024, respectively. As a result of this acquisition, the Company recognized property, plant and equipment of $2.6 million, intangible liability of $0.2 million, and noncontrolling interest of $2.1 million in the unaudited condensed consolidated balance sheet.

Amended Rated Term Loan

As part of the Blackstone Capital Facility, APA Finance, LLC (“APAF”), a wholly owned subsidiary of the Company, entered into a $251.0 million term loan facility with Blackstone Insurance Solutions ("BIS") through a consortium of lenders, which consists of investment grade-rated Class A and Class B notes (the "Rated Term Loan").

On August 25, 2021, APAF entered into an Amended and Restated Credit Agreement with BIS to refinance the Rated Term Loan (the “Amended Rated Term Loan”). The Amended Rated Term Loan added $135.6 million to the facility, bringing the aggregate facility to $503.0 million. The Amended Rated Term Loan has a weighted average 3.51% annual fixed rate, reduced from the previous weighted average rate of 3.70%, and matures on February 29, 2056 (“Final Maturity Date”).

The Amended Rated Term Loan amortizes at an initial rate of 2.5% of outstanding principal per annum for a period of 8 years at which point the amortization steps up to 4% per annum until September 30, 2031 (“Anticipated Repayment Date”). After the Anticipated Repayment Date, the loan becomes fully-amortizing, and all available cash is used to pay down principal until the Final Maturity Date.

As of September 30, 2022, the outstanding principal balance of the Rated Term Loan was $490.3 million less unamortized debt discount and loan issuance costs totaling $7.8 million. As of December 31, 2021, the outstanding principal balance of the Rated Term Loan was $500.0 million less unamortized debt discount and loan issuance costs totaling $8.4 million.

As of September 30, 2022, the Company was in compliance with all covenants. As of December 31, 2021, the Company was in compliance with all covenants, except the delivery of the APAF audited consolidated financial statements, for which the Company obtained a waiver to extend the financial statement reporting deliverable due date. The Company delivered the audited financial statements on May 25, 2022, before the extended reporting deliverable due date.

Construction to Term Loan Facility

On January 10, 2020, APA Construction Finance, LLC (“APACF”) a wholly-owned subsidiary of the Company, entered into a credit agreement with Fifth Third Bank, National Association and Deutsche Bank AG New York Branch to fund the development and construction of future solar facilities (“Construction Loan to Term Loan Facility”). The Construction Loan to Term Loan Facility includes a construction loan commitment of $187.5 million and a letter of credit commitment of $12.5 million, which can be drawn until January 10, 2023.

The construction loan commitment can convert to a term loan upon commercial operation of a particular solar energy facility. In addition, the Construction Loan to Term Loan Facility accrued a commitment fee at a rate equal to 0.50% per year of the daily unused amount of the commitment. As of September 30, 2022, the outstanding principal balances of the construction loan and term loan were zero and $16.0 million, respectively. As of December 31, 2021, the outstanding principal balances of the construction loan and term loan were $5.6 million and $12.3 million, respectively. As of September 30, 2022, and December 31, 2021, the Company had an unused borrowing capacity of $171.5 million and $169.7 million, respectively. For the three months ended September 30, 2022, and 2021, the Company incurred interest costs associated with outstanding construction loans totaling zero and $0.1 million, respectively. For the nine months ended September 30, 2022, and 2021 the Company incurred interest costs associated with outstanding construction loans totaling zero and $0.4 million, respectively. These interest costs were capitalized as part of property, plant and equipment. The Construction Loan to Term Loan Facility includes various financial and other covenants for APACF and the Company, as guarantor. As of September 30, 2022, and December 31, 2021, the Company was in compliance with all covenants.

Project-Level Term Loan

In conjunction with the Stellar NJ 2 Acquisition, the Company assumed a project-level term loan with an outstanding principal balance of $14.1 million and a fair value discount of $2.2 million. The term loan is subject to scheduled semi-annual amortization and interest payments, and matures on September 1, 2029.

As of September 30, 2022, the outstanding principal balance of the term loan is $12.6 million, less unamortized debt discount of $2.2 million, which was recognized as part of the acquisition. During the nine months ended September 30, 2022, the Company incurred interest costs associated with the term loan of $0.2 million.

The term loan is secured by an interest in the underlying solar project assets and the revenues generated by those assets. As of September 30, 2022, the Company was in compliance with all covenants.

Letter of Credit Facilities

On October 23, 2020, the Company entered into a letter of credit facility with Fifth Third Bank for the total capacity of $10.0 million. Additionally, in conjunction with the Stellar NJ 2 Acquisition, the Company entered into a cash collateralized letter of credit with Fifth Third Bank with a total capacity of $2.1 million.

As of September 30, 2022, and December 31, 2021, the total letters of credit outstanding with Fifth Third Bank were $12.1 million with an unused capacity of zero. As of September 30, 2022, and December 31, 2021, the total letters of credit outstanding with Deutsche Bank were $0.7 million and $0.6 million, respectively, with an unused capacity of $11.8 million and $11.9 million, respectively. To the extent liabilities are incurred as a result of the activities covered by the letters of credit, such liabilities are included on the accompanying condensed consolidated balance sheets. From time to time, the Company is required to post financial assurances to satisfy contractual and other requirements generated in the normal course of business. Some of these assurances are posted to comply with federal, state or other government agencies’ statutes and regulations. The Company sometimes uses letters of credit to satisfy these requirements and these letters of credit reduce the Company’s borrowing facility capacity.

Financing Lease Obligations

From time to time, the Company sells equipment to third parties and enters into master lease agreements to lease the equipment back for an agreed-upon term. Due to certain forms of continuous involvement provided by the master lease agreements, sale leaseback accounting is prohibited under ASC 840. Therefore, the Company accounts for these transactions using the financing method by recognizing the sale proceeds as a financing obligation and the assets subject to the sale-leaseback remain on the balance sheet of the Company and are being depreciated. The aggregate proceeds have been recorded as long-term debt within the condensed consolidated balance sheets.

As of September 30, 2022 and December 31, 2021, the Company's recorded financing obligations were $36.0 million, net of $1.1 million of deferred transaction costs, and $36.5 million, net of $1.1 million of deferred transaction costs, respectively. Payments of $0.9 million and $0.1 million were made under financing lease obligations for the three months ended September 30, 2022, and 2021, respectively. Payments of $1.5 million and $0.1 million were made under financing obligations for the nine months ended September 30, 2022 and 2021, respectively. Interest expense, inclusive of the amortization of deferred transaction costs, for the three months ended September 30, 2022, and 2021, was $0.4 million and $0.2 million, respectively. Interest expense, inclusive of the amortization of deferred transaction costs, for the nine months ended September 30, 2022 and 2021, was $1.1 million and $0.2 million, respectively.

The table below shows the minimum lease payments under the financing lease obligations for the years ended:

2022	$	709

2024	2,340
2025	2,353
2026	2,336
Thereafter	14,993
Total	$	25,067

The difference between the outstanding financing lease obligation of $37.1 million and $25.1 million of minimum lease payments, including the residual value guarantee, is due to $13.2 million of investment tax credits claimed by the Lessor, less $2.6 million of the implied interest on financing lease obligation included in minimum lease payments. The remaining difference is due to $1.3 million of interest accrued and a $0.1 million difference between the minimum lease payments and the fair value of financing lease obligations acquired.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value MeasurementsThe Company measures certain assets and liabilities at fair value, which is defined as the price that would be received from the sale of an asset or paid to transfer a liability (i.e., an exit price) on the measurement date in an orderly transaction between

market participants in the principal or most advantageous market for the asset or liability. Our fair value measurements use the following hierarchy, which prioritizes valuation inputs based on the extent to which the inputs are observable in the market.

•Level 1 - Valuation techniques in which all significant inputs are unadjusted quoted prices from active markets for assets or liabilities that are identical to the assets or liabilities being measured.

•Level 2 - Valuation techniques in which significant inputs include quoted prices from active markets for assets or liabilities that are similar to the assets or liabilities being measured and/or quoted prices for assets or liabilities that are identical or similar to the assets or liabilities being measured from markets that are not active. Also, model-derived valuations in which all significant inputs are observable in active markets are Level 2 valuation techniques.

•Level 3 - Valuation techniques in which one or more significant inputs are unobservable. Such inputs reflect our estimate of assumptions that market participants would use to price an asset or liability.

The Company holds various financial instruments that are not required to be recorded at fair value. For cash, restricted cash, accounts receivable, accounts payable, and short-term debt, the carrying amounts approximate fair value due to the short maturity of these instruments.

Redeemable Warrant Liability

CBAH sold 10,062,500 warrants as part of the SAILSM (Stakeholder Aligned Initial Listing) securities in the CBAH initial public offering (which traded separately on the NYSE under the symbol “CBAH WS” prior to the Merger, and following the Merger trade under the symbol “AMPS WS”) (such warrants, the "Redeemable Warrants"). The Redeemable Warrants are exercisable for an aggregate of 10,062,500 shares of the Company's Class A common stock, par value $0.0001 per share (the "Class A common stock"), at a purchase price of $11.00 per share. CBAH also issued 7,366,667 warrants to CBRE Acquisition Sponsor, LLC (the “Sponsor”) in a private placement simultaneously with the closing of the CBAH IPO and 2,000,000 warrants to the Sponsor in full settlement of a second amended and restated promissory note with the Sponsor (such warrants, the "Private Placement Warrants"). The Private Placement Warrants are identical to the Redeemable Warrants except that, so long as they are held by the Sponsor, officers or directors or their respective permitted transferees, (i) they will not be redeemable by the Company (except in certain circumstances), (ii) they may be exercised by the holders on a cashless basis, and (iii) they (including the shares of our Class A common stock issuable upon exercise of these warrants) are entitled to registration rights. If the Private Placement Warrants are held by holders other than the Sponsor, officers or directors or their respective permitted transferees, the Private Placement Warrants will become redeemable by the Company in all redemption scenarios and exercisable by the holders on the same basis as the Redeemable Warrants. The Private Placement Warrants will be exercisable for an aggregate of 9,366,667 shares of CBAH Class A common stock at a purchase price of $11.00 per share.

Redeemable warrants, including Private Placement Warrants, are not considered to be “indexed to the Company’s own stock.” This provision precludes the Company from classifying the Redeemable warrants, including Private Placement Warrants, in stockholders’ equity. As the Redeemable warrants, including Private Placement Warrants, meet the definition of a derivative, the Company recorded these warrants as liabilities on the condensed consolidated balance sheet at fair value, with subsequent changes in their respective fair values recognized in the consolidated statements of operations at each reporting date.

On May 31, 2022, June 15, 2022, and August 17, 2022, and the Company entered into separate, privately negotiated warrant exchange agreements (the "Exchange Agreements") with a limited number of holders of the Company's outstanding Redeemable Warrants. Pursuant to the Exchange Agreements, the Company agreed to issue an aggregate of 1,111,243 shares of Class A common stock to the holders of Redeemable Warrants in exchange for the surrender and cancellation of an aggregate of 4,630,163 Redeemable Warrants. The issuance by the Company of the shares of Common Stock in exchange for the surrender and cancellation of the Redeemable Warrants was made in reliance on the exemption from registration in Section 3(a)(9) of the Securities Act. Immediately prior to the exchange, the Redeemable Warrants were remeasured to fair value based on the trading price of the exchanged shares of common stock, resulting in a gain on fair value remeasurement of $4.1 million within operating income in the condensed consolidated statements of operations for the nine months ended September 30, 2022, and a redeemable warrant liability of $7.8 million, which was then reclassified to additional paid-in capital in the condensed consolidated balance sheet as of September 30, 2022.

On September 15, 2022, the Company issued a notice for redemption of all 14,798,981 of the Company's outstanding Redeemable Warrants at 5:00 p.m. New York City time on October 17, 2022 (the “Redemption Date”) for a redemption price of $0.10 per Warrant (the “Redemption Price”). Holders could elect to exercise their Warrants on a “cashless basis” and surrender

the Redeemable Warrants for that number of shares of Class A Common Stock that is determined by reference to the table set forth in Section 6.2 of the Warrant Agreement based on the Redemption Date and the Redemption Fair Market Value of $10.98. Given the Redemption Fair Market Value and the Redemption Date, the number of shares of Class A Common Stock to be issued for each Redeemable Warrant that is exercised through a cashless exercise is 0.2763.

As of September 30, 2022, holders of 1,687 Redeemable Warrants exercised their Redeemable Warrants with the payment of cash and the Company received $18,557 of cash proceeds. Holders of 10,614,564 Redeemable Warrants exercised their Redeemable Warrants on a cashless basis in exchange for 2,932,779 shares of Class A Common Stock per Redeemable Warrants. Immediately prior to the exercise, the Redeemable Warrants were remeasured to fair value based on the trading price of the exchanged shares of common stock, resulting in a loss on fair value remeasurement of $8.6 million within operating income in the condensed consolidated statements of operations for the nine months ended September 30, 2022, and a redeemable warrant liability of $35.8 million, which was then reclassified to additional paid-in capital in the condensed consolidated balance sheet as of September 30, 2022.

As the remaining Redeemable Warrants (other than our Private Placement Warrants) continue to trade separately on the NYSE following the Merger as of September 30, 2022, the Company determines the fair value of the Redeemable Warrants based on the quoted trading price of those warrants. As the inputs are observable and reflect quoted trading price, the overall fair value measurement of the Redeemable Warrants, excluding Private Placement Warrants, is classified as Level 1. The Private Placement Warrants have the same redemption and make-whole provisions as the Redeemable Warrants. Therefore, the fair value of the Private Placement Warrants is equal to the Redeemable Warrants. Private Placement Warrants are considered Level 2 as they are measured at fair value using observable inputs for similar assets in an active market.

As of the Redemption Date, holders of 8,462 Redeemable Warrants exercised their Redeemable Warrants with the payment of cash and the Company received $93,082 of cash proceeds. Holders of 14,690,310 Redeemable Warrants exercised their Redeemable Warrants on a cashless basis in exchange for 4,058,845 shares of Class A Common Stock per Redeemable Warrant. A total of 100,209 Warrants remained unexercised as of the Redemption Date, and the Company redeemed those Warrants for an aggregate redemption price of $10,021. The Redeemable Warrants have been delisted from the NYSE, and there are no Redeemable Warrants left outstanding subsequent to the Redemption Date.

Alignment Shares Liability

As of September 30, 2022, the Company has 1,207,500 alignment shares outstanding, all of which are held by the Sponsor, certain former officers of CBAH (such officers, together with the Sponsor, the “Sponsor Parties”) and former CBAH directors. The alignment shares will automatically convert into shares of Class A common stock based upon the Total Return (as defined in Exhibit 4.4 to our 2021 Annual Report on Form 10-K) on the Class A common stock as of the relevant measurement date over each of the seven fiscal years following the Merger.

Upon the consummation of the Merger, alignment shares have no continuing service requirement and do not create an unconditional obligation requiring the Company to redeem the instruments by transferring assets. In addition, the shares convert to a variable number of Class A common stock depending on the trading price of the Class A common stock and dividends paid/payable to the holders of Class A common stock. Therefore, the shares do not represent an obligation or a conditional obligation to issue a variable number of shares with a monetary value based on any of the criteria in ASC 480, Distinguishing Liabilities From Equity. The Company determined that the alignment shares meet the definition of a derivative because they contain (i) an underlying (Class A common stock price), (ii) a notional amount (a fixed number of Class B common stock), (iii)

no or minimal initial net investment (the Sponsor paid a de minimis amount which is less than the estimated fair value of the shares), and (iv) net settleable through a conversion of the Alignment shares into Class A shares. As such, the Company concluded that the alignment shares meet the definition of a derivative, which will be presented at fair value each reporting period, with changes in fair value recorded through earnings.

The Company estimates the fair value of outstanding alignment shares using a Monte Carlo simulation valuation model utilizing a distribution of potential outcomes based on a set of underlying assumptions such as stock price, volatility, and risk-free interest rate. As volatility of 73% and risk-free interest rate of 4.0% are not observable inputs, the overall fair value measurement of alignment shares is classified as Level 3. Unobservable inputs can be volatile and a change in those inputs might result in a significantly higher or lower fair value measurement of Alignment shares.

Contingent Consideration

Solar Acquisition

In connection with the acquisition of a portfolio of sixteen solar energy facilities with a combined nameplate capacity of 61.5 MW on December 22, 2020 (the "Solar Acquisition"), contingent consideration of up to an aggregate of $10.5 million may be payable upon achieving certain market power rates and actual power volumes generated by the acquired solar energy facilities. The Company estimated the fair value of the contingent consideration for future earnout payments using a Monte Carlo simulation model. Significant assumptions used in the measurement include the estimated volumes of power generation of acquired solar energy facilities during the 18-36-month period since the acquisition date, market power rates during the 36-month period, and the risk-adjusted discount rate associated with the business. As the inputs are not observable, the overall fair value measurement of the contingent consideration is classified as Level 3. Liability for the contingent consideration is included in other long-term liabilities in the condensed consolidated balance sheets at the estimated fair value of $2.7 million and $2.3 million as of September 30, 2022 and December 31, 2021, respectively. For the three and nine months ended September 30, 2022, the Company recorded $0.8 million loss and $0.1 million gain on fair value remeasurement of contingent consideration within operating income in the condensed consolidated statements of operations, respectively. For the three and nine months ended September 30, 2021, the Company recorded $0.4 million and $2.4 million gain on fair value remeasurement of contingent consideration within operating income in the condensed consolidated statements of operations, respectively. Gain and loss was recorded due to changes in significant assumptions used in the measurement, including the actual versus estimated volumes of power generation of acquired solar energy facilities and market power rates.

Other

Gain on fair value remeasurement of other contingent consideration of $0.5 million was recorded within operating income in the condensed consolidated statements of operations for the nine months ended September 30, 2022. No gain or loss on fair value remeasurement of contingent consideration was recorded for the nine months ended September 30, 2021.

(1) The calculation of basic weighted average shares of common stock outstanding excludes 542,511 shares of the Company's Class A common stock provided to holders of Legacy Altus common stock, including shares that were subject to vesting conditions (the "Altus Restricted Shares") for the three and nine months ended September 30, 2022, and 1,259,887 shares of Company Class A common stock provided to holders of Altus Restricted Shares for the three and nine months ended September 30, 2021. The calculation of diluted weighted average shares of common stock for the three and nine months ended September 30, 2022, and 2021, also excludes these shares because their inclusion would have had an anti-dilutive effect.

(2) Excludes 4,182,730 Redeemable Warrants for the three and nine months ended September 30, 2022. The Redeemable Warrants are exercisable at $11.00 per share. As the warrants are deemed anti-dilutive, they are excluded from the calculation of earnings per share.

(3) Excludes 2,323,574 shares of the Company's Class A common stock provided to holders of restricted stock units granted under the Omnibus Incentive Plan for the three and nine months ended September 30, 2022, because their inclusion would have had an anti-dilutive effect.

Share-Based Payment Arrangement [Abstract]

Stock-based Compensation

Stock-Based CompensationThe Company recognized $2.7 million and approximately zero of stock-based compensation expense for the three months ended September 30, 2022, and 2021, respectively. The Company recognized $6.7 million and $0.1 million of stock-based compensation expense for the nine months ended September 30, 2022, and 2021, respectively. As of September 30, 2022, and

December 31, 2021, the Company had $35.9 million and $0.2 million of unrecognized share-based compensation expense related to unvested restricted units, respectively, which the Company expects to recognize over a weighted-average period of approximately five years.

Legacy Incentive Plans

Prior to the Merger, Altus maintained the APAM Holdings LLC Restricted Units Plan, adopted in 2015 (the “APAM Plan”) and APAM Holdings LLC adopted the 2021 Profits Interest Incentive Plan (the “Holdings Plan”, and together with the APAM Plan, the “Legacy Incentive Plans”), which provided for the grant of restricted units that were intended to qualify as profits interests to employees, officers, directors and consultants. In connection with the Merger, vested restricted units previously granted under the Legacy Incentive Plans were exchanged for shares of Class A Common Stock, and unvested Altus Restricted Shares under each of the Legacy Incentive Plans were exchanged for restricted Class A Common Stock with the same vesting conditions. As of September 30, 2022, and December 31, 2021, zero and 446,128 shares of Class A Common Stock were restricted under the APAM Plan, respectively. As of September 30, 2022, and December 31, 2021, 542,511 and 813,759 shares of Class A Common Stock were restricted under the Holdings Plan, respectively. No further awards will be made under the Legacy Incentive Plans.

The fair value of the granted units was determined using the Black-Scholes Option Pricing model and relied on assumptions and inputs provided by the Company. All option models utilize the same assumptions with regard to (i) current valuation, (ii) volatility, (iii) risk-free interest rate, and (iv) time to maturity. The models, however, use different assumptions with regard to the strike price which vary by award.

Omnibus Incentive Plan

On July 12, 2021, the Company entered into the Management Equity Incentive Letter with each of Mr. Felton and Mr. Norell pursuant to which, on February 15, 2022, the Compensation Committee granted to Mr. Felton and Mr. Norell, together with other senior executives, including Anthony Savino, Chief Construction Officer, and Dustin Weber, Chief Financial Officer, restricted stock units (“RSUs”) under the Omnibus Incentive Plan (the "Incentive Plan") that are subject to time-based and, for the named executive officers and certain other executives, eighty percent (80%) of such RSUs also further subject to performance-based vesting, with respect to an aggregate five percent (5%) of the Company’s Class A common stock on a fully diluted basis, excluding the then-outstanding shares of the Company’s Class B common stock or any shares of the Company’s Class A common stock into which such shares of the Company’s Class B common stock are or may be convertible. Subject to continued employment on each applicable vesting date, the time-based RSUs generally vest 33 1/3% on each of the third, fourth and fifth anniversaries of the Closing, and the performance-based RSUs vest with respect to 33 1/3% of the award upon the achievement of the above time-based requirement and the achievement of a hurdle representing a 25% annual compound annual growth rate measured based on an initial value of $10.00 per share.

As of September 30, 2022, and December 31, 2021, there were 23,047,325 and 15,364,883 shares of the Company's Class A common stock authorized for issuance under the Incentive Plan, respectively. The number of shares authorized for issuance under the Incentive Plan will increase on January 1 of each year from 2022 to 2031 by the lesser of (i) 5% of the number of shares outstanding as of the close of business on the immediately preceding December 31 and (ii) the number of shares determined by the Company's board of directors. For the three months ended September 30, 2022, the Company granted 155,000 RSUs and recognized $2.7 million of stock compensation expense in relation to the incentive plan. For the nine months ended September 30, 2022, the Company granted 8,043,914 RSUs and recognized $6.7 million of stock-based compensation expense in relation to the Incentive Plan.

Employee Stock Purchase Plan

On December 9, 2021, we adopted the 2021 Employee Stock Purchase Plan ("ESPP"), which provides a means by which eligible employees may be given an opportunity to purchase shares of the Company’s Class A common stock. As of September 30, 2022, and December 31, 2021, there were 3,072,976 and 1,536,488 shares of the Company's Class A common stock authorized for issuance under the ESPP, respectively. The number of shares authorized for issuance under the ESPP will increase on January 1 of each year from 2022 to 2031 by the lesser of (i) 1% of the number of shares outstanding as of the close of business on the immediately preceding December 31 and (ii) the number of shares determined by the Company's board of directors. No shares of the Company’s Class A common stock were issued and no stock-based compensation expense was recognized in relation to the ESPP for the three and nine months ended September 30, 2022.

Income Taxes

Income Taxes

The income tax provision for interim periods is determined using an estimate of the Company’s annual effective tax rate as adjusted for discrete items arising in that quarter.

For the three months ended September 30, 2022, and 2021, the Company had income tax expense of $2.0 million and income tax benefit of $2.6 million, respectively. For the nine months ended September 30, 2022, and 2021, the Company had income tax expense of $2.5 million and income tax benefit of $1.5 million, respectively. For the three and nine months ended September 30, 2022, the effective tax rate differs from the U.S. statutory rate primarily due to effects of non-deductible compensation, noncontrolling interests, redeemable noncontrolling interests, fair value adjustments for warrant liabilities and alignment shares, as well as state and local income taxes. For the three and nine months ended September 30, 2021, the effective tax rate differs from the U.S. statutory rate primarily due to effects of noncontrolling interests, redeemable noncontrolling interests, state and local income taxes, and gain on fair value remeasurement of contingent consideration.

Acquisition of DESRI II Acquisition Holdings, L.L.C. & DESRI V Acquisition Holdings, L.L.C.

On November 11, 2022, the Company acquired all of the outstanding membership interests in DESRI II Acquisition Holdings, L.L.C. and DESRI V Acquisition Holdings, L.L.C. (the "DESRI II & V Acquisition") from DESRI II, L.L.C. and DESRI V, L.L.C., respectively, under definitive Membership Interest Purchase Agreements that were announced on September 27, 2022. As a result of the DESRI II & V Acquisition, the Company acquired approximately 88 MW of operating solar facilities for total consideration at closing of approximately $102.0 million, including $82.0 million paid at closing and funded by cash on hand, and $20.0 million, payable within twelve to eighteen months, subject to customary hold back conditions.

The initial accounting for the DESRI II & V Acquisition, including the estimated fair value of the assets acquired and liabilities assumed, is incomplete as a result of the proximity of the acquisition date to the date these financial statements were issued.

The Company prepares its unaudited condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and regulations of the U.S. Securities and Exchange Commission ("SEC") for interim financial reporting. The Company’s condensed consolidated financial statements include the results of wholly-owned and partially-owned subsidiaries in which the Company has a controlling interest. All intercompany balances and transactions have been eliminated in consolidation.

Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2021 filed with the Company’s 2021 annual report on Form 10-K on March 24, 2022, and the related notes which provide a more complete discussion of the Company’s accounting policies and certain other information. The information as of December 31, 2021, included in the condensed consolidated balance sheets was derived from the Company’s audited consolidated financial statements. The condensed consolidated financial statements were prepared on the same basis as the audited consolidated financial statements and reflect all adjustments, including normal recurring adjustments, which are, in the opinion of management, necessary for a fair statement of the Company’s financial position as of September 30, 2022, and the results of operations and cash flows for the three and nine months ended September 30, 2022, and

2021. The results of operations for the three and nine months ended September 30, 2022, are not necessarily indicative of the results that may be expected for the full year or any other future interim or annual period.

Use of Estimates

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates.

In recording transactions and balances resulting from business operations, the Company uses estimates based on the best information available. Estimates are used for such items as the fair value of net assets acquired in connection with accounting for business combinations, the useful lives of the solar energy facilities, and inputs and assumptions used in the valuation of asset retirement obligations (“AROs”), contingent consideration, and alignment shares.

Segment Information

Segment Information Operating segments are defined as components of a company about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company’s chief operating decision makers are the co-chief executive officers. Based on the financial information presented to and reviewed by the chief operating decision makers in deciding how to allocate the resources and in assessing the performance of the Company, the Company has determined it operates as a single operating segment and has one reportable segment, which includes revenue under power purchase agreements, revenue from net metering credit agreements, solar renewable energy certificate revenue, rental income, performance-based incentives, and other revenue. The Company’s principal operations, revenue and decision-making functions are located in the United States.

Cash, Cash Equivalents, and Restricted Cash

Cash, Cash Equivalents, and Restricted Cash

Cash and cash equivalents includes all cash balances on deposit with financial institutions and readily marketable securities with original maturity dates of three months or less at the time of acquisition that are denominated in U.S. dollars. Pursuant to the budgeting process, the Company maintains certain cash and cash equivalents on hand for possible equipment replacement related costs.

The Company records cash that is restricted as to withdrawal or use under the terms of certain contractual agreements as restricted cash. Restricted cash is included in current portion of restricted cash and restricted cash, noncurrent portion on the condensed consolidated balance sheets and includes cash held with financial institutions for cash collateralized letters of credit pursuant to various financing and construction agreements.

Concentration of Credit Risk

Concentration of Credit Risk

The Company maintains its cash in bank deposit accounts which, at times, may exceed Federal Deposit Insurance Corporation insurance limits. The Company has not experienced any losses in such accounts and believes it is not exposed to any significant credit risk on cash balances.

Accounting Pronouncements

Accounting Pronouncements

As a public company, the Company is provided the option to adopt new or revised accounting guidance as an “emerging growth company” under the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) either (1) within the same periods as those otherwise applicable to public business entities, or (2) within the same time periods as non-public business entities, including early adoption when permissible. The Company expects to elect to adopt new or revised accounting guidance within the same time period as non-public business entities, as indicated below.

Recent Accounting Pronouncements Adopted

In December 2019, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2019-12, Income Taxes (Topic 740), which simplifies the accounting for income taxes, primarily by eliminating certain exceptions to ASC 740. This standard is effective for fiscal periods beginning after December 15, 2020. The Company has adopted this standard as of the first quarter of 2021 and did not have a material impact on the condensed consolidated financial statements.

Recent Accounting Pronouncements Not Yet Adopted

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which primarily changes the lessee’s accounting for operating leases by requiring recognition of lease right-of-use assets and lease liabilities. This standard is effective for annual reporting periods beginning after December 15, 2021. The Company expects to adopt this guidance in fiscal year 2022. The Company is continuing the analysis of the contractual arrangements that may qualify as leases under the new standard and expects the most significant impact will be the recognition of the right-of-use assets and lease liabilities on the consolidated balance sheets.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and has since released various amendments including ASU No. 2019-04. The new standard generally applies to financial assets and requires those assets to be reported at the amount expected to be realized. The ASU is effective for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact of this guidance on its consolidated financial statements.

Fair Value Measurements

The Company measures certain assets and liabilities at fair value, which is defined as the price that would be received from the sale of an asset or paid to transfer a liability (i.e., an exit price) on the measurement date in an orderly transaction between

market participants in the principal or most advantageous market for the asset or liability. Our fair value measurements use the following hierarchy, which prioritizes valuation inputs based on the extent to which the inputs are observable in the market.

•Level 1 - Valuation techniques in which all significant inputs are unadjusted quoted prices from active markets for assets or liabilities that are identical to the assets or liabilities being measured.

•Level 2 - Valuation techniques in which significant inputs include quoted prices from active markets for assets or liabilities that are similar to the assets or liabilities being measured and/or quoted prices for assets or liabilities that are identical or similar to the assets or liabilities being measured from markets that are not active. Also, model-derived valuations in which all significant inputs are observable in active markets are Level 2 valuation techniques.

•Level 3 - Valuation techniques in which one or more significant inputs are unobservable. Such inputs reflect our estimate of assumptions that market participants would use to price an asset or liability.

The Company holds various financial instruments that are not required to be recorded at fair value. For cash, restricted cash, accounts receivable, accounts payable, and short-term debt, the carrying amounts approximate fair value due to the short maturity of these instruments.

Earnings Per Share [Abstract]

Schedule of Earnings Per Share, Basic and Diluted

The calculation of basic and diluted earnings per share for the three and nine months ended September 30, 2022 and 2021, was as follows (in thousands, except share and per share amounts):

	For the three months ended September 30,				For the nine months ended September 30,
	2022		2021		2022		2021
Net loss attributable to common stockholders - basic and diluted	(96,980)		(1,055)		(12,446)		(1,282)
Class A Common Stock
Weighted average shares of common stock outstanding - basic(1)	154,455,228		88,741,089		153,482,503		88,741,089
Weighted average shares of common stock outstanding - diluted(1)(2)(3)	154,455,228		88,741,089		153,482,503		88,741,089
Net loss attributable to common stockholders per share - basic and diluted	$	(0.63)	$	(0.01)	$	(0.08)	$	(0.01)

(1) The calculation of basic weighted average shares of common stock outstanding excludes 542,511 shares of the Company's Class A common stock provided to holders of Legacy Altus common stock, including shares that were subject to vesting conditions (the "Altus Restricted Shares") for the three and nine months ended September 30, 2022, and 1,259,887 shares of Company Class A common stock provided to holders of Altus Restricted Shares for the three and nine months ended September 30, 2021. The calculation of diluted weighted average shares of common stock for the three and nine months ended September 30, 2022, and 2021, also excludes these shares because their inclusion would have had an anti-dilutive effect.

(2) Excludes 4,182,730 Redeemable Warrants for the three and nine months ended September 30, 2022. The Redeemable Warrants are exercisable at $11.00 per share. As the warrants are deemed anti-dilutive, they are excluded from the calculation of earnings per share.

(3) Excludes 2,323,574 shares of the Company's Class A common stock provided to holders of restricted stock units granted under the Omnibus Incentive Plan for the three and nine months ended September 30, 2022, because their inclusion would have had an anti-dilutive effect.
