Explanation of Responses:
(1)	Represents restricted stock units ("RSUs") granted to the Reporting Person pursuant to a Director Offer Letter agreement, dated December 9, 2021, between the Reporting Person and the Issuer, pursuant to which the Reporting Person will receive RSUs as a portion of the Reporting Person's compensation for services to the Issuer as a Director. Each RSU represents the right to receive one share of Common Stock. The RSUs vest as follows: (i) 10,000 RSUs vest in equal annual installments on each of the first two anniversaries of the consummation of the Issuer's business combination transaction on December 9, 2021 (the "Vesting Commencement Date"); and (ii) 10,500 RSUs vest in full on the first anniversary of the Vesting Commencement Date, in each case subject to the Reporting Person's continued service to the Issuer through each such date.
(2)	Pursuant to the terms of the Class B common stock of the Issuer (the "Class B Common Stock"), of which an aggregate of 1,408,750 shares are currently outstanding, on the last day of each measurement period, which will occur annually over seven fiscal years following the completion of the business combination of CBRE Acquisition Holdings, Inc. with Altus Power, Inc., which occurred on December 9, 2021, an aggregate of 201,250 shares of Class B Common Stock will automatically convert, subject to adjustment, into shares of Class A Common Stock, pursuant to a formula based on the stock price of the Class A Common Stock, into an aggregate minimum of 2,013 shares of Class A Common Stock on each conversion date, up to an aggregate maximum of 14,596,637 shares of Class A Common Stock over such seven year period.
(3)	The number of shares of Class A Common Stock reported as underlying such shares of Class B Common Stock in the Table above represents the approximate maximum number of shares of Class A Common Stock that may be delivered with respect to shares of Class B Common Stock reported above by the Reporting Person based on proportionate ownership of shares of Class B Common Stock.
(4)	Each Warrant is initially exercisable for one share of Class A Common Stock at an exercise price of $11.00 per share, subject to certain adjustments. The Warrants became exercisable on January 8, 2022 and expire on December 9, 2026, or earlier upon redemption or liquidation.
