Previous Earnings Reports
| Date | Event | Sentiment | Move | Catalyst |
|---|---|---|---|---|
| Oct 28 | Q3 2025 earnings | Positive | -0.3% | Reported $410.4M revenue, highest in two years, with strong margins and cash. |
| Jul 22 | Q2 2025 earnings | Positive | -14.2% | Q2 revenue grew to $363.2M with record 190.9 MWh battery shipments and $1.53B cash. |
| Apr 22 | Q1 2025 earnings | Negative | -15.7% | Revenue fell to $356.1M with U.S. demand softness despite strong margins and cash. |
| Feb 04 | Q4 2024 earnings | Positive | -1.5% | Q4 2024 revenue rose to $382.7M with 53.2% non-GAAP margin and strong FCF. |
| Oct 22 | Q3 2024 earnings | Positive | -14.9% | Revenue jumped to $380.9M with robust shipments and $1.77B cash reserves. |
Earnings releases often trigger sizeable moves for ENPH, with several fundamentally positive reports followed by negative price reactions, indicating a pattern of market skepticism around results and guidance.
Across the last five earnings releases from Oct 2024 through Oct 2025, Enphase reported revenues in the roughly mid-$300M to low-$400M range, generally highlighting strong non-GAAP gross margins and solid cash positions. Nevertheless, four of these events saw negative next-day price moves, sometimes in double digits, despite positive operational metrics such as record revenues or healthy U.S. manufacturing volumes. Today’s Q4/FY 2025 report, with revenue of $343.3M and detailed 2026 guidance, fits into this history of closely scrutinized earnings updates.
Historical Comparison
Over the past five earnings reports, ENPH’s average next-day move was about 9.3%. Today’s roughly -1.4% reaction to Q4/FY 2025 results is relatively muted versus that history.
From Q3 2024 through Q3 2025, Enphase maintained quarterly revenues mostly in the mid-$300M to low-$400M range while emphasizing high non-GAAP gross margins, expanding U.S. manufacturing, and strong cash balances. The current Q4/FY 2025 release extends that trajectory with detailed safe harbor contributions and 2026 margin guidance, showing continuity in financial discipline despite shifting regional demand.
Market Pulse Summary
This announcement delivers a detailed look at Q4 and full-year 2025 performance, with revenue of $343.3M, non-GAAP gross margin of 46.1%, and FY 2025 revenue of $1.47B. Management highlights strong cash of $1.51B, ongoing U.S. manufacturing, and guidance for Q1 2026 revenue of $270M–$300M and margins under continued tariff pressure. Investors may monitor regional demand trends, safe harbor contributions, and execution on new products like IQ9 commercial microinverters and PowerMatch software.

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.
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.
