Any statements that are not of historical fact, may be forward-looking statements. Words used such as “anticipates,” “believes,” “could,” “potential,” “predicts,”“continues,” “designed,” “estimates,” “expects,” “goal,” “intends,” “likely,” “may,” “ongoing,” “plans,” “projects,” “pursuing,” “seeks,” “should,” “will,” “would” and similar expressions are intended to identify forward-looking statements, although not allforward-looking statements contain these words. All forward-looking statements are based on Enphase Energy’s current assumptions, expectations and beliefs, and involve substantial risks and uncertainties that may cause results, performance or achievementto materially differ from those expressed or implied by these forward-looking statements. You are cautioned that these forward-looking statements are only predictions and may differ materially from actual future events or results. A detailed discussion of risk factors that affect Enphase Energy’s business is included in the filings it makes with the Securities and Exchange Commission (SEC) from time to time, including its most recent reports on Form 10-K and Form 10-Q, particularly under the heading “Risk Factors.” Copies of these filings are available on Enphase Energy’s website through its investor pageor on the SEC website.All forward-looking statements in this presentation are based on information currently available to Enphase Energy, and Enphase Energy assumes no obligation to update these forward-looking statements in light of new information or future events.Industry InformationInformation regarding market and industry statistics in this presentation is based on information available to Enphase Energy that Enphase Energy believe is accurate. It is generally based on publications that are not produced for purposes of economic analysis.Non-GAAP Financial MetricsEnphase Energy has presented certain non-GAAP financial measures in this presentation. Generally, a non-GAAP financial measure is a numerical measure of a company’s performance, financial position, or cash flows that either exclude or include amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with generally accepted accounting principles in the United States (GAAP). Reconciliation of each non-GAAP financial measure to the most directly comparable GAAP financial measure can be found in the accompanying tables to this presentation. Non-GAAP financial measures presented by Enphase Energy include non-GAAP gross profit, gross margin, operating expenses, income from operations, net income, and net income per share (basic and diluted).These non-GAAP financial measures do not reflect a comprehensive system of accounting, differ from GAAP measures with the same captions and may differ from non-GAAP financial measures with the same or similar captions that are used by other companies. In addition, these non-GAAP measures have limitations in that they do not reflect all of the amounts associated with Enphase Energy’s results of operations as determined in accordance with GAAP. As such, these non-GAAP measures should be considered as a supplement to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. Enphase Energy uses these non-GAAP financial measures to analyze its operating performance and future prospects, develop internal budgets and financial goals, and to facilitate period-to-period comparisons. Enphase Energy believes that these non-GAAP financial measures reflect an additional way of viewing aspects of its operations that, when viewed with its GAAP results, provide a more complete understanding of factors and trends affecting its business.As presented in the “Reconciliation of Non-GAAP Financial Measures” page, each of the non-GAAP financial measures excludes one or more of the following items for purposes of calculating non-GAAPfinancial measures to facilitate an evaluation of Enphase Energy’s current operating performance and a comparison to its past operating performance: •Stock-based compensation expense. Enphase Energy excludes stock-based compensation expense from its non-GAAP measures primarily because they are non-cash in nature. Moreover, the impact of this expense is significantly affected by Enphase Energy’s stock price at the time of an award over which management has limited to no control.•Acquisition related amortization. This item represents amortization of acquired intangible assets, which is a non-cash expense. Acquisition related amortization of acquired intangible assets are not reflective of Enphase Energy’s ongoing financial performance.•Restructuring and asset impairment charges. Enphase Energy excludes restructuring and asset impairment charges due to the nature of the expenses being unusual and arising outside the ordinary course of continuing operations. These costs primarily consist of fees paid for cash-based severance costs, accelerated stock-based compensation expense and asset write-downs of property and equipment and acquired intangible assets, and other contract termination costs resulting from restructuring initiatives.•Non-cash interest expense. This item consists primarily of amortization of debt issuance costs and accretion of debt discount because these expenses do not represent a cash outflow for Enphase Energy except in the period the financing was secured and such amortization expense s not reflective of Enphase Energy’s ongoing financial performance.•Non-GAAP income tax adjustment. This item represents the amount adjusted to Enphase Energy’s GAAP tax provision or benefit to present the non-GAAP tax amount based on cash tax expense and reserves for periods prior to 2023. Effective January 1, 2023, Enphase Energy updated its methodology of computing the non-GAAP income tax adjustment from reporting cash tax expense and reserves to the projected non-GAAP annualized effective tax rate as Enphase Energy utilized most of its net operating loss and tax credit carryforwards in the year ended December 31, 2022, and became a significant cash taxpayer in the United States. Going forward, Enphase Energy will exclude the income tax effects of GAAP adjustments such as stock-based compensation, amortization of purchased intangibles, and other non-recurring items that are not reflective of Enphase Energy ongoing financial performance.
