(In thousands, except per share and percentage data)

Total revenue for the second quarter of 2025 was $363.2 million, compared to $356.1 million in the first quarter of 2025. Our revenue in the second quarter of 2025 included $40.4 million of safe harbor revenue, compared to $54.3 million of safe harbor revenue in the first quarter. Our revenue in the United States for the second quarter of 2025 increased approximately 3%, compared to the first quarter. The increase was the result of seasonality partially offset by lower safe harbor revenue. Our revenue in Europe increased approximately 11% for the second quarter of 2025, compared to the first quarter. The increase in revenue was primarily due to higher microinverter and battery sales as we continued to ramp shipments of our IQ® Battery 5P™ with FlexPhase during the second quarter.

Our non-GAAP gross margin was 48.6% in the second quarter of 2025, compared to 48.9% in the first quarter. Our non-GAAP gross margin, excluding net benefit from the Inflation Reduction Act (IRA), was 37.2% in the second quarter of 2025, compared to 38.3% in the first quarter. The reciprocal tariffs had a negative impact of approximately two percentage points on margins.

Our non-GAAP operating expenses were $77.8 million in the second quarter of 2025, compared to $79.4 million in the first quarter. Our non-GAAP operating income was $98.6 million in the second quarter of 2025, compared to $94.6 million in the first quarter.

We exited the second quarter of 2025 with $1.53 billion in cash, cash equivalents and marketable securities and generated $26.6 million in cash flow from operations in the second quarter. Our capital expenditures were $8.2 million in the second quarter of 2025, compared to $14.6 million in the first quarter of 2025.

In the second quarter of 2025, we repurchased 702,948 shares of our common stock at an average price of $42.67 per share for a total of approximately $30.0 million. We also spent approximately $3.0 million by withholding shares to cover taxes for employee stock vesting that reduced the diluted shares by 58,332 shares.

During the second quarter of 2025, we shipped approximately 1.41 million microinverters from manufacturing facilities in the United States that we booked for 45X production tax credits. We continued to ship our IQ8HC™ Microinverters, IQ8P-3P™ Commercial Microinverters, and IQ® Battery 5Ps from these facilities, meeting domestic content requirements.

Enphase Energy has presented certain non-GAAP financial measures in this press release. 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 press release. Non-GAAP financial measures presented by Enphase Energy include non-GAAP gross profit, gross margin, operating expenses, income from operations, net income, net income per share (basic and diluted), net IRA benefit, and free cash flow.

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” tables below, each of the non-GAAP financial measures excludes one or more of the following items for purposes of calculating non-GAAP financial 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 is 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 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.

Non-GAAP net income per share, diluted. Enphase Energy excludes the dilutive effect of in-the-money portion of convertible senior notes as they are covered by convertible note hedge transactions that reduce potential dilution to our common stock upon conversion of the Notes due 2025, Notes due 2026, and Notes due 2028, and includes the dilutive effect of employee’s stock-based awards and the dilutive effect of warrants. Enphase Energy believes these adjustments provide useful supplemental information to the ongoing financial performance.

Net IRA benefit. This item represents the advanced manufacturing production tax credit (AMPTC) from the IRA for manufacturing microinverters in the United States, partially offset by the incremental manufacturing cost incurred in the United States relative to manufacturing in India. The AMPTC is accounted for by Enphase Energy as an income-based government grants that reduces cost of revenues in the condensed consolidated statements of operations.

Free cash flow. This item represents net cash flows from operating activities less purchases of property and equipment.
