Total revenue for the third quarter of 2026 was $293.3 million, compared to $291.9 million in the second quarter. Third-quarter revenue included $85.0 million of safe harbor revenue, compared to $84.3 million in the second quarter. Revenue in the United States increased approximately 3%, a smaller than anticipated increase due to soft residential solar demand. Revenue in Europe decreased approximately 11%, due to summer seasonality and continued weakness in certain solar markets.

Global sell-through increased approximately 1% sequentially in the third quarter of 2026, below our expectation of 10% growth, contributing to revenue at the low end of our guidance range. U.S. sell-through increased 5% sequentially, but declined 35% year-over-year, broadly in line with third-party reports of U.S. residential solar market trends. European sell-through declined 12% sequentially in the third quarter, reflecting seasonality and softer demand, particularly in France.

Non-GAAP gross margin was 45.0% in the third quarter, compared to 46.8% in the second quarter. The decrease in gross margin was driven by product mix. Reciprocal tariffs reduced gross margin by approximately 1.3 percentage points, down from approximately 2.0 percentage points in the second quarter.

Non-GAAP operating expenses were $78.4 million in the third quarter, compared to $79.8 million in the second quarter. Non-GAAP operating income decreased to $53.6 million, compared to $56.7 million in the second quarter.

We exited the third quarter of 2026 with $931.8 million in cash, cash equivalents and marketable securities, and generated approximately $0.1 million in cash flow from operations. Capital expenditures were $11.5 million, compared to $14.4 million in the second quarter.

We shipped 129.9 MWh of IQ Batteries in the third quarter, compared to 113.8 MWh in the second quarter. More than 26,000 installers worldwide are now certified to install IQ Batteries, up from more than 25,000 in the second quarter.

We announced a major milestone in the development of the IQ® Solid-State Transformer (IQ SST), successfully demonstrating 13.8 kV AC to 800 VDC conversion at our R&D lab in Austin, Texas. The demonstration brought together 132 power modules, with 44 connected in series on each of three phases, operating as a single integrated system. Importantly, IQ SST maintained a stable 800 VDC output during rapid load changes that simulate the dynamic power demands of AI compute racks.

By converting medium-voltage AC directly to 800 VDC, IQ SST is designed to eliminate multiple stages of conventional power conversion, reduce energy losses, and deliver more usable power to AI compute. Our next milestones are to validate operation at 34.5 kV and demonstrate a megawatt-scale system by the end of 2026.

During the third quarter of 2026, we more than doubled our IQ SST customer and partner pipeline to over 50. We are actively engaged with a leading hyperscaler and a global AI computing leader, whose technical requirements are helping shape our product architecture and roadmap. These engagements reinforce our confidence in the market opportunity. We remain on track for customer pilots in 2027, with commercial shipments expected to begin in 2028.

Our core U.S. residential solar market continues to face headwinds from higher interest rates and the expiration of the Section 25D federal tax credit. We are addressing these near-term challenges while positioning Enphase for a new phase of growth, driven by five key growth drivers heading into 2027: our fifth-generation IQ® Battery G5 for global residential storage markets; the Propel prepaid lease program to drive U.S. residential solar and battery adoption; commercial solar with our IQ9™ Commercial Microinverters and our upcoming IQ® Battery C80 in the United States; unidirectional and bidirectional EV chargers for global markets; and IQ SST for next-generation AI data centers. Together, we believe these opportunities expand our addressable market, leverage our power electronics expertise, and position Enphase for sustainable long-term growth.

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:

Tariff refunds. This item represents refunds received for tariffs previously imposed under the International Emergency Economic Powers Act, which were invalidated following the United States Supreme Court ruling in Learning Resources, Inc. v. Trump. Enphase Energy received refunds and associated interest of approximately $52.0 million during the nine months ended September 30, 2026 from U.S. Customs and Border Protection related to tariffs paid during fiscal 2025 and the first quarter of fiscal 2026, of which approximately $1.6 million and $47.0 million was recognized as a reduction to cost of revenues during the three and nine months ended September 30, 2026, respectively; approximately $0.1 million and $1.7 million was recognized as interest income in the three and nine months ended September 30, 2026, respectively; and approximately $3.3 million was capitalized as a cost of inventory as of September 30, 2026. Of the $47.0 million refunds recognized as a reduction to cost of revenues, $43.3 million of the tariff costs incurred were previously recorded as a cost of revenues in prior periods and are excluded from non‑GAAP measures, along with the associated $1.7 million interest earned from those payments, as they are related to prior periods and not reflective of Enphase Energy’s ongoing financial performance.

AMPTC adjustment. In the first quarter of 2026, Enphase Energy decided to sell its Advanced Manufacturing Production Tax Credit (AMPTC) generated in 2025 and going forward in the tax credit transfer market. Enphase Energy sold $235.0 million of AMPTC generated in 2025 at 93% of face value, resulting in a discount of approximately $16.5 million. Enphase Energy also incurred approximately $2.5 million in transaction-related fees. Because these amounts relate to AMPTC generated in the prior fiscal year and do not reflect Enphase Energy’s ongoing operating performance, Enphase Energy excluded them from its non-GAAP financial measures for the first quarter of 2026.

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 expenses and amortization. This item represents costs incurred in connection with acquisition-related activities, which are not indicative of normal, recurring operating expenses, and amortization of acquired intangible assets, which is a non-cash expense. Acquisition related expenses and amortization of acquired intangible assets are not reflective of Enphase Energy’s ongoing financial performance.

Restructuring and asset impairment. Enphase Energy excludes restructuring and asset impairment 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’s 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 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.
