Total revenue for the third quarter of 2025 was $410.4 million, our highest revenue level in two years, compared to $363.2 million in the second quarter of 2025. Our revenue in the third quarter of 2025 included $70.9 million of safe harbor revenue, compared to $40.4 million of safe harbor revenue in the second quarter. Our revenue in the United States for the third quarter of 2025 increased approximately 29%, compared to the second quarter. The increase in revenue was the result of higher demand and safe harbor revenue. Our revenue in Europe decreased approximately 38% for the third quarter of 2025, compared to the second quarter. The decline was a result of further softening in European demand.
Our non-GAAP gross margin was 49.2% in the third quarter of 2025, compared to 48.6% in the second quarter of 2025. Our non-GAAP gross margin, excluding net benefit from the Inflation Reduction Act (IRA), was 38.9% in the third quarter of 2025, compared to 37.2% in the second quarter. The reciprocal tariffs had a negative impact of 4.9 percentage points on margins in the third quarter of 2025, compared to approximately two percentage points on margins in the second quarter.
Our non-GAAP operating expenses were $78.5 million in the third quarter of 2025, compared to $77.8 million in the second quarter of 2025. Our non-GAAP operating income was $123.4 million in the third quarter of 2025, compared to $98.6 million in the second quarter of 2025.
We exited the third quarter of 2025 with $1.48 billion in cash, cash equivalents and marketable securities and generated $13.9 million in cash flow from operations in the third quarter of 2025. Our capital expenditures were $8.0 million in the third quarter of 2025, compared to $8.2 million in the second quarter of 2025.
In the third quarter of 2025, as part of our anti-dilution plan, we spent approximately $1.7 million by withholding shares to cover taxes for employee stock vesting that reduced the diluted shares by 49,023 shares. There were no repurchases of common stock in the third quarter of 2025. We have a remaining $268.7 million authorized for further share repurchases.
During the third quarter of 2025, we shipped approximately 1.53 million microinverters from manufacturing facilities in the United States that we booked for 45X production tax credits. We are shipping our IQ8HC™ Microinverters, IQ8P-3P™ Commercial Microinverters, IQ® Battery 5Ps, and IQ® Battery 10Cs from these facilities, meeting domestic content requirements.
We shipped a record 195.0 MWh of IQ Batteries in the third quarter of 2025, compared to 190.9 MWh in the second quarter of 2025. More than 19,500 installers worldwide are certified to install our IQ Batteries, compared to more than 11,700 installers worldwide in the second quarter.
During the third quarter of 2025, we ramped shipments of our 4th-generation Enphase® Energy System, featuring the IQ Battery 10C, IQ® Meter Collar, and the IQ® Combiner 6C with integrated load control to customers in the United States. Customer feedback has been positive, as the system stands out for its smaller footprint, enhanced features, easy installation, and reliability. The IQ Meter Collar is now approved by 39 utilities across the United States.
We expect to begin shipments of our new IQ9N-3P™ Commercial Microinverter and IQ® EV Charger 2 to customers in the United States during the fourth quarter of 2025. The IQ9N-3P Commercial Microinverter is our first microinverter powered by Gallium Nitride (GaN) technology. Designed for three-phase 480Y/277 V grids, IQ9N-3P helps simplify the design, lower installation and balance-of-system costs, and improve system efficiency for 480 V commercial projects. The IQ EV Charger 2, currently shipping to 18 countries in Europe, Australia, and New Zealand, is our most advanced residential charger to date. It is designed to work seamlessly with Enphase solar and battery systems or as a powerful standalone charger.
In Europe, we recently announced expanded support for virtual power plants (VPPs). Enphase products now enable advanced energy market steering smart grid features like one-minute data streaming, instant alerts for VPP events and system maintenance, and solar curtailment to support grid constraints. In addition, we expanded IQ® Energy Management capabilities to include select electric water heaters in Belgium, the Netherlands, and Switzerland. Powered by the IQ® Energy Router, the update gives homeowners greater control over when and how they use energy – coordinating solar, batteries, EV chargers, heat pumps, and water heaters within a single, integrated system.

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), 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.
