STAMFORD, Conn, August 14, 2023 – Altus Power, Inc. (NYSE: AMPS) (“Altus Power,” “we,” “us,” “our,” or the “Company”), the leading commercial-scale provider of clean electric power, today announced its financial results for the second quarter of 2023.

“The second quarter was the best in company history in terms of revenue and adjusted EBITDA and thanks to our increasing construction output and our continued success in acquiring assets, we are now the largest owner of commercial solar arrays in the country,” said Lars Norell, Co-CEO of Altus Power. “These important milestones, combined with our use of Community Solar initiatives to maximize our asset sizes, enhance our customer reach as we continue our profitable growth in this expanding market.”

“At a time when others in our industry are having difficulty accessing capital, our thoughtful balance sheet construction including our strategic partnership with Blackstone Structured Finance affords us the ability to execute on our robust pipeline of opportunity,” said Gregg Felton, CO-CEO of Altus Power. “Our strong first half of 2023 positions us well to continue expanding our footprint as we work to achieve our goal of delivering the benefits of clean, electric power coast-to-coast.”

Second Quarter Financial Results

Operating revenues during the second quarter of 2023 totaled $46.5 million, compared to $24.8 million during the same period of 2022, an increase of 88%. The increase is primarily due to a greater number of solar energy facilities in operation as a result of construction completions as well as acquisitions during the past twelve months.

Second quarter 2023 GAAP net income totaled $3.4 million, compared to $21.6 million for the same period last year. The decrease was primarily driven by changes in the non-cash remeasurement of alignment shares.

Adjusted EBITDA* during the second quarter of 2023 was $30.6 million, compared to $13.9 million for the second quarter of 2022, a 120% increase. The year-over-year growth in adjusted EBITDA* was primarily the result of increased revenue from additional solar energy facilities, partially offset by an increase in our general and administrative expenses associated with an increase in personnel.

2023 Guidance

Altus Power reaffirmed 2023 adjusted EBITDA* in the range of $97-103 million, representing 70% growth over 2022 at the midpoint. The Company also continues to expect 2023 adjusted EBITDA margin* to be in the mid-to-high fifty percent range.

Use of Non-GAAP Financial Information

*Denotes non-GAAP financial measure. We present our operating results in accordance with accounting principles generally accepted in the U.S. (“GAAP”). We believe certain financial measures, such as adjusted EBITDA and adjusted EBITDA margin provide users of our financial statements with supplemental information that may be useful in evaluating our business. The presentation of non-GAAP financial information is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP.

We define adjusted EBITDA as net income (loss) 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 on fair value remeasurement of contingent consideration, gain on disposal of property, plant and equipment, change in fair value of redeemable warrant liability, change in fair value of alignment shares, loss on extinguishment of debt, and other miscellaneous items of other income and expenses. See below for explanations of each of these components.

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

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 GAAP and should not be viewed as an alternative to GAAP measures of performance. The 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 GAAP results, as we believe it provides a more complete understanding of ongoing business performance and trends than 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 GAAP.

In addition to adjusted EBITDA, we may also refer to exit portfolio annualized rate, or exit PAR, which is a non-GAAP measure. Exit PAR reflects the estimated annual adjusted EBITDA potential of our operating asset base at the end of the year and assumes customary weather, production, expenses and other economic and market conditions. We believe this metric can be helpful to assess our portfolio asset base in operation at the beginning of an annual period, e.g. if we were to receive the benefit of assets added for a full year even if they were added during a partial year. This figure is only an estimate and is based on a number of assumptions by Altus Power's management that may or may not be realized.

Altus Power does not provide GAAP financial measures on a forward-looking basis because the Company is unable to predict with reasonable certainty and without unreasonable effort, items such as acquisition and entity formation costs, gain on fair value remeasurement of contingent consideration, change in fair value of redeemable warrant liability, change in fair value of alignment shares. These items are uncertain, depend on various factors, and could be material to Altus Power’s results computed in accordance with GAAP.

Adjusted EBITDA Definitions

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.

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.

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.

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.

Stock-Based Compensation Expense. Stock-based compensation expense is recognized for awards granted under the Legacy Incentive Plans and Omnibus Incentive Plan, as defined in our 2022 Annual Report on Form 10K, Note 20, "Stock-Based Compensation," to our consolidated financial statements.

Fair Value Remeasurement of Contingent Consideration. In connection with the Solar Acquisition (as defined in our 2022 Annual Report on Form 10K, Note 11, “Fair Value Measurements,” to our consolidated financial statements) contingent consideration of up to an aggregate of $3.1 million may be payable upon achieving certain market power rates 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 market power rates during the 36-month period, and the risk-adjusted discount rate associated with the business.

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 through the Redemption Date, and the resulting loss was included in the consolidated statements of operations.

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 business combination (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 December 31, 2022, and the resulting gain was included in the 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 interest income, state grants, and other miscellaneous items.

Non-GAAP Definitions Adjusted EBITDA is a non-GAAP financial measure and is defined as net income (loss) plus net interest expense, depreciation, amortization and accretion expense, income tax expense, acquisition and entity formation costs, stock-based 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 on fair value remeasurement of contingent consideration, gain on disposal of property, plant and equipment, change in fair value of redeemable warrant liability, change in fair value of alignment shares, loss on extinguishment of debt, and other miscellaneous items of other income and expenses. Adjusted EBITDA margin is a non-GAAP financial measure and is defined as Adjusted EBITDA divided by operating revenues. Adjusted EBITDA and adjusted EBITDA margin are non-GAAP financial measures that we use to measure out performance. We believe that investors and analysts also use adjusted EBITDA in evaluating our operating performance. This measurement is not recognized in accordance with GAAP and should not be viewed as an alternative to GAAP measures of performance. The 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 GAAP results, as we believe it provides a more complete understanding of ongoing business performance and trends than 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 GAAP. Altus Power does not provide GAAP financial measures on a forward-looking basis because the Company is unable to predict with reasonable certainty and without unreasonable effort, items such as acquisition and entity formation costs, gain on fair value remeasurement of contingent consideration, change in fair value of redeemable warrant liability, change in fair value of alignment shares. These items are uncertain, depend on various factors, and could be material to Altus Power’s results computed in accordance with GAAP. 18

Adjusted EBITDA Definitions 19 Adjusted EBITDA and Adjusted EBITDA Margin We define adjusted EBITDA as net income plus net interest expense, depreciation, amortization and accretion expense, income tax expense, acquisition and entity formation costs, stock-based 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, loss on extinguishment of debt, and other miscellaneous items of other income and expenses. See "Components of Results of Operations" below for a description of each of these items. 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. 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. 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. 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. Stock-Based Compensation Expense. Stock-based compensation expense is recognized for awards granted under the Legacy Incentive Plans and Omnibus Incentive Plan, as defined in 2022 Annual Report on Form 10K, Note 20, "Stock-Based Compensation," to our consolidated financial statements included elsewhere in this Report. Fair Value Remeasurement of Contingent Consideration. In connection with the Solar Acquisition (as defined in 2022 Annual Report on Form 10K, Note 11, “Fair Value Measurements,” to our consolidated financial statements included elsewhere in this Report), contingent consideration of up to an aggregate of $3.1 million may be payable upon achieving certain market power rates 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 market power rates during the 36-month period, and the risk-adjusted discount rate associated with the business. 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 through the Redemption Date, and the resulting loss was included in the consolidated statements of operations. Change in Fair Value of Alignment Shares. 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 December 31, 2022, and the resulting gain was included in the 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 interest income, state grants, and other miscellaneous items.
