Fair Value Measurements

9 Months Ended

Sep. 30, 2022

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.
