Diluted EPS $ 0.27 $ (0.06) $ 0.28 $ 0.46 $ 0.47 $ 0.69

Total revenue for the second quarter of 2026 was $291.9 million, compared to $282.9 million in the first quarter of 2026. Second-quarter revenue included $84.3 million of safe harbor revenue, compared to $34.5 million in the first quarter. Revenue in the United States decreased approximately 3%, while revenue in Europe increased approximately 35%.

Non-GAAP gross margin was 46.8% in the second quarter, up from 43.9% in the first quarter. Reciprocal tariffs reduced gross margin by approximately 2.0 percentage points, down from approximately 4.3 percentage points in the first quarter.

Non-GAAP operating expenses were $79.8 million in the second quarter, compared to $77.0 million in the first quarter, primarily due to increased investment in R&D. Non-GAAP operating income increased to $56.7 million, compared to $47.3 million in the first quarter.

We exited the second quarter of 2026 with $937.7 million in cash, cash equivalents and marketable securities, and generated $40.3 million in cash flow from operations. Capital expenditures were $14.4 million, compared to $19.9 million in the first quarter.

During the second quarter, we received approximately $41.0 million in refunds from U.S. Customs and Border Protection (CBP), followed by an additional $11.0 million after quarter end. The full $52.0 million impacted second-quarter GAAP results. Of this amount, $45.4 million was recognized as an increase to GAAP gross profit, improving GAAP gross margin by 15.6 percentage points; $1.6 million was recognized as GAAP interest income; and $5.0 million was capitalized as inventory as of June 30, 2026.

We shipped 113.8 MWh of IQ Batteries in the second quarter, compared to 103.1 MWh in the first quarter. More than 25,000 installers worldwide are now certified to install IQ Batteries, up from more than 24,000 in the first quarter.

During the second quarter, we accelerated development of the IQ® Solid-State Transformer (IQ SST) for next-generation AI data centers. We are actively engaged with customers and ecosystem partners, with a few opportunities advancing to the RFI and RFP stages and representing a potential multi-gigawatt pipeline. We achieved important milestones across the IQ SST power module, medium-voltage transformer, and system-control architecture, including a 15-module series stack operating at 4.16 kV AC with droop control, and remain on track for a full-system demonstration later this year.

We expanded our commercial portfolio during the second quarter. In the United States, we began shipping our IQ9S-3P™ Commercial Microinverter, a GaN-based 548 W microinverter designed for 480 V three-phase systems. Together with the IQ9N-3P™ Commercial Microinverter, the IQ9S-3P broadens our offering for the U.S. commercial solar market.

We also launched our IQ9N™ Residential Microinverter in the United States and key European markets in June 2026, followed by Australia and New Zealand in July. Built with advanced GaN technology, the IQ9N is designed to pair with today’s high-power residential solar modules and help maximize energy harvest and system performance.

At Intersolar Europe in June 2026, we showcased our upcoming IQ® Battery G5. This AC-coupled battery is designed to provide higher energy density and flexible capacity through stackable 5 kWh modules that can scale up to 30 kWh. It uses 100 Ah prismatic cells and is expected to deliver approximately 50% higher energy density than the fourth-generation IQ® Battery 10C, while reducing cost by approximately 40%.

We also showcased our IQ® Bidirectional EV Charger at Intersolar Europe. Built on our GaN power platform and designed to support modern 800 V DC electric vehicle architectures, the charger is engineered to move power efficiently and bidirectionally between the grid-facing AC system and the vehicle. We are collaborating with several leading global automotive manufacturers to support the adoption of this product.

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. The Company received refunds and associated interest of approximately $41.0 million and $11.0 million in the three months ended June 30, 2026 and in July 2026, respectively, from CBP related to tariffs paid during fiscal 2025 and the first quarter of fiscal 2026, of which $45.4 million was recognized as a reduction to cost of revenues during the three and six months ended June 30, 2026, $1.6 million was recognized as interest income in the three and six months ended June 30, 2026, and $5.0 million was capitalized as a cost of inventory as of June 30, 2026. Of the $45.4 million refunds recognized as a reduction to cost of revenues, $43.4 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 $1.6 million interest earned from those payments, as they are related to prior periods and not reflective of the Company’s ongoing financial performance.

AMPTC adjustment. In the first quarter of 2026, the Company decided to sell its Advanced Manufacturing Production Tax Credit (AMPTC) generated in 2025 and going forward in the tax credit transfer market. The Company sold $235.0 million of AMPTC generated in 2025 at 93% of face value, resulting in a discount of approximately $16.5 million. The Company 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 the Company’s ongoing operating performance, the Company 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 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 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.
