Total revenue for the fourth quarter of 2025 was $343.3 million, compared to $410.4 million in the third quarter of 2025. Our revenue in the fourth quarter included $20.3 million of safe harbor revenue, compared to $70.9 million of safe harbor revenue in the third quarter. Our revenue in the United States for the fourth quarter decreased approximately 13%, compared to the third quarter, primarily due to the lower safe harbor and storage revenue. Our revenue in Europe for the fourth quarter decreased approximately 29%, compared to the third quarter. The decline was a result of further softening in European demand.
The sell-through demand for our products in the United States increased 21% in the fourth quarter of 2025, compared to the third quarter of 2025, and was at our highest level in more than two years. This was driven by increased solar and battery installations ahead of the Section 25D tax credit expiration, which allowed us to reduce inventory in the channel to healthy levels exiting the fourth quarter.
Our non-GAAP gross margin was 46.1% in the fourth quarter of 2025, compared to 49.2% in the third quarter of 2025. The reciprocal tariffs had a negative impact of 5.1 percentage points on margins in the fourth quarter, compared to approximately 4.9 percentage points on margins in the third quarter.
Our non-GAAP operating expenses were $78.8 million in the fourth quarter of 2025, compared to $78.5 million in the third quarter of 2025. Our non-GAAP operating income was $79.4 million in the fourth quarter, compared to $123.4 million in the third quarter.
We exited the fourth quarter of 2025 with $1.51 billion in cash, cash equivalents and marketable securities and generated $47.6 million in cash flow from operations. Our capital expenditures were $9.7 million in the fourth quarter, compared to $8.0 million in the third quarter.
In the fourth quarter of 2025, as part of our anti-dilution plan, we spent approximately $1.4 million by withholding shares to cover taxes for employee stock vesting that reduced the diluted shares by 41,767 shares. There were no repurchases of common stock in the fourth quarter. We have $268.7 million remaining under our current share repurchase authorization.
During the fourth quarter of 2025, we shipped approximately 1.31 million microinverters from our U.S. manufacturing facilities that we booked for 45X production tax credits, along with 51.1 MWh of IQ Batteries, supporting domestic content requirements. We shipped a total of 150.1 MWh of IQ Batteries in the fourth quarter of 2025, compared to 195.0 MWh in the third quarter. More than 22,000 installers worldwide are certified to install our IQ Batteries, compared to more than 19,500 installers worldwide in the third quarter.
In December of 2025, we began shipping our U.S.-manufactured IQ9N-3P commercial microinverter and IQ® EV Charger 2 across the United States. The IQ9N-3P microinverter helps eligible commercial projects meet domestic content and Foreign Entity of Concern (FEOC) requirements and is our first GaN-based microinverter for three-phase 480Y/277 V (wye) grids. The IQ EV Charger 2, our most advanced residential charger, works with Enphase solar and battery systems or as a standalone charger and is also available in Europe, Australia, Canada, and New Zealand.
During the fourth quarter of 2025, we launched PowerMatch™, a software-enabled technology that dynamically matches the IQ® Battery output to real-time home demand, increasing usable energy, extending battery life, and improving performance by up to 40%. Unlike hybrid systems that push all power through a single large inverter, PowerMatch activates only the microinverters needed, reducing losses at low loads, so customers get more usable energy from the same battery capacity.

Use of non-GAAP Financial Measures
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), 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.
4


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