That May Affect Future Results

The following presentation for Altus Power, Inc. ("Altus Power" or the "Company") has been prepared by Altus Power's management. You should read the presentation together with our consolidated financial statements and related notes appearing in our 2023 Annual Report on Form 10-K filed with the Securities and Exchange Commission (SEC) on March 14, 2024 (the "2023 Annual Report on Form 10-K"). Any references in this section to "we," "our" or "us" shall mean Altus Power. In addition to historical information, this presentation contains statements that are considered "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995, as amended. These statements do not convey historical information but relate to predicted or potential future events and financial results, such as statements of our plans, strategies and intentions, or our future performance or goals that are based upon management's current expectations. Our forward-looking statements can often be identified by the use of forward-looking terminology such as "aims," "believes," "expects," "intends," "may," "could," "will," "should," "plans," "projects," "forecasts," "seeks," "anticipates," "goal," "objective," "target," "estimate," "future," "outlook," "strategy," "vision," or variations of such words or similar terminology. Investors and prospective investors are cautioned that such forward-looking statements are only projections based on current estimations. These statements involve risks and uncertainties and are based upon various assumptions. Such risks and uncertainties include, but are not limited to, the risks as described in the "Risk Factors" in our 2023 Annual Report on Form 10-K These risks and uncertainties, among others, could cause our actual future results to differ materially from those described in our forward-looking statements or from our prior results. Any forward-looking statement made by us in this presentation is based only on information currently available to us and speaks to circumstances only as of the date on which it is made. Except as required by applicable law, we are not obligated to update these forward-looking statements, even though our situation may change in the future.

Such forward-looking statements are subject to known and unknown risks, uncertainties, assumptions and other important factors, many of which are outside Altus Power's control, that could cause actual results to differ materially from the results discussed in the forward-looking statements. These risks, uncertainties, assumptions and other important factors include, but are not limited to: (1) the risk that pending acquisitions may not close in the anticipated timeframe or at all due to a closing condition not being met; (2) failure to obtain required consents or regulatory approvals in a timely manner or otherwise; (3) the ability of Altus Power to successfully integrate into its business and recognize the anticipated benefits of recently completed business combinations and related transactions and generate profit from their operations; (4) the ability of Altus Power to retain customers and maintain and expand relationships with business partners, suppliers and customers; (5) the risk of litigation and/or regulatory actions related to the proposed acquisition of solar assets; and (6) the possibility that Altus Power may be adversely affected by other economic, business, regulatory and/or competitive factors.

The presentation includes financial information not prepared in accordance with generally accepted accounting principles ("Non-GAAP Financial Measures"). A reconciliation of the Non-GAAP Financial Measures to financial information prepared in accordance with generally accepted accounting principles ("GAAP"), as required by Regulation G, appears in the presentation, except where there is no comparable GAAP financial measure. The Company is providing disclosure of the reconciliation of reported Non-GAAP Financial Measures used in the presentation, among other places, to its comparable financial measures on a GAAP basis. The Company believes that the Non-GAAP Financial Measures provide investors additional ways to view our operations, when considered with both our GAAP results and the reconciliation to net income and net cash provided by operating activities, which we believe provide a more complete understanding of our business than could be obtained absent this disclosure. We believe the Non-GAAP Financial Measures also provide investors a useful tool to assess shareholder value.
