Altus Power, Inc. (NYSE: AMPS) (“Altus Power” or the “Company”), the largest commercial scale provider of clean, electric power, today announced its financial results for the second quarter of 2024.

“Altus Power has assembled a portfolio of highly attractive assets that will generate long-term value for our investors. In Q2 2024, we continued to prudently scale our portfolio and capitalize on long-term growth opportunities,” said Gregg Felton, CEO of Altus Power. “Over the past five years, our flexible and agile but disciplined approach has allowed us to increase our revenues and adjusted EBITDA four-fold, while building the largest nationwide portfolio in the commercial solar market.”

Second Quarter Financial Results

Operating revenues during the second quarter of 2024 totaled $52.5 million, compared to $46.5 million during the same period of 2023, an increase of 13%. The increase is primarily due to the greater number of solar energy facilities placed in service or onboarded during the past twelve months and resulting increased sales of energy to customers.

Second quarter 2024 GAAP net income totaled $33.1 million, compared to $3.4 million for the same period of 2023. The increase was primarily driven by the non-cash gain from remeasurement of alignment shares.

Adjusted EBITDA* during the second quarter of 2024 was $31.2 million, compared to $30.6 million for the second quarter of 2023, a 2% 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 operating expenses as well as general and administrative expenses attributable to increased personnel to support our ongoing growth initiatives.

2024 Guidance

The company announced plans to revise its previously stated guidance range of $200-222 million of revenue and $115-135 million of adjusted EBITDA*, to $196-201 million of revenue and $111-115 million of adjusted EBITDA* for FY2024. At the same time, the company reaffirmed its previously stated 3-year guidance of 20-30% CAGR on megawatts and 20-25% CAGR on revenue and adjusted EBITDA*.

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 plus net interest expense, depreciation, amortization and accretion expense, income tax expense or benefit, acquisition and entity formation costs, stock-based compensation expense or benefit, 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, gain or loss on disposal of property, plant and equipment, change in fair value of Alignment Shares liability, loss on extinguishment of debt, CEO transition costs, and other miscellaneous items of other income and expenses.

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 and adjusted EBITDA margin in evaluating our operating performance. These measurements are 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 and adjusted EBITDA margin 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. Factors in this determination include the exclusion of (1) variability due to gains or losses related to fair value remeasurement of contingent consideration and the change in fair value of Alignment Shares liability, (2) strategic decisions to acquire businesses, dispose of property, plant and equipment or extinguish debt, and (3) the non-recurring nature of stock-based compensation, CEO transition costs, and other miscellaneous items of income and expense, which affect results in a given period or periods. In addition, adjusted EBITDA represents the business performance of the Company before the application of statutory income tax rates and tax adjustments corresponding to the various jurisdictions in which the Company operates, as well as interest expense and depreciation, amortization and accretion expense, which are not representative of our ongoing operating performance.

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 annual recurring revenues, or ARR, which is a non-GAAP measure. ARR is an estimate that management uses to determine the expected annual revenue potential of our operating asset base at the end of a calendar year. ARR assumes customary weather, production, expenses and other economic and market conditions, as well as seasonality. It is not derived from a GAAP financial measure so it is difficult to provide a meaningful reconciliation to GAAP. The elements of our financial statements that are considered or evaluated in determining our ARR are the following: the estimated megawatt hours of generation assuming all new build and operating assets added any time during the year were in place for the full year and the estimated power prices for such assets based on historical power prices. 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 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 acquire PPA and NMCA customers, value ascribed to in-place leases, and favorable and unfavorable rate revenues contracts. Value ascribed to in-place leases is amortized using the straight-line method ratably over 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 and 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 an annual 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 and Benefit. Stock-based compensation expense is recognized for awards granted under the Legacy Incentive Plans and Incentive Plan, as defined in Note 14, "Stock-Based Compensation," to our condensed consolidated financial statements included in our Quarterly Report on Form 10-Q for the six months ended June 30, 2024.

Fair Value Remeasurement of Contingent Consideration. In connection with various acquisitions, contingent consideration may be payable upon achieving certain conditions. The Company estimates the fair value of contingent consideration using a Monte Carlo simulation model or an expected cash flow approach. Significant assumptions used in the measurement of fair value of contingent consideration associated with various acquisitions include market power rates, estimated volumes of power generation of acquired solar energy facilities, percentage of completion of in-development solar energy facilities, and the risk-adjusted discount rate associated with the business.

Gain or Loss on Disposal of Property, Plant and Equipment. In connection with the disposal of assets, the Company recognizes a gain or loss on disposal of property, plant and equipment, which represents the difference between the consideration received and the carrying value of the disposed asset.

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 June 30, 2024, and the resulting gain 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 and Expense, Net. Other income and expenses primarily represent interest income, and other miscellaneous items.

CEO Transition Costs. CEO transition costs represent costs recognized in connection with the resignation of Lars Norell as Co-Chief Executive Officer and director of the Company on April 28, 2024.
