Organization, Consolidation and Presentation of Financial Statements [Abstract]
DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION	DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION Description of Business Enphase Energy, Inc. (the “Company”) is a global energy technology company. The Company delivers smart, easy-to-use solutions that manage solar generation, storage and communication on one platform. Basis of Presentation and Consolidation The accompanying condensed consolidated financial statements are presented in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Certain prior period amounts have been reclassified to conform to the current period presentation. Unaudited Interim Financial Information These accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) for interim financial reporting. In the opinion of management, these unaudited condensed consolidated financial statements reflect all adjustments, consisting of normal recurring items, considered necessary to present fairly the Company’s financial condition, results of operations, comprehensive income, stockholders’ equity and cash flows for the interim periods indicated. The results of operations for the three and six months ended June 30, 2026 are not necessarily indicative of the operating results for the full year. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Significant estimates and assumptions reflected in the financial statements include revenue recognition, allowance for credit losses, stock-based compensation, income tax provision, inventory valuation, government grants, accrued warranty obligations, fair value of debt securities, convertible notes, fair value of acquired intangible assets and goodwill, useful lives of acquired intangible assets and property and equipment, incremental borrowing rate for right-of-use assets and lease liability. These estimates are based on information available as of the date of the financial statements; therefore, actual results could differ materially from those estimates due to risks and uncertainties. The year-end condensed consolidated balance sheet data was derived from audited consolidated financial statements but does not include all disclosures required by U.S. GAAP. The Company filed audited consolidated financial statements, which included all information and notes necessary for such a complete presentation, in conjunction with its Annual Report on Form 10-K for the year ended December 31, 2025 filed with the SEC on February 17, 2026 (the “Form 10‑K”). Summary of Significant Accounting Policies There have been no changes to the Company’s significant accounting policies as described in Note 2, “Summary of Significant Accounting Policies”, of the notes to consolidated financial statements included in Part II, Item 8 of the Form 10-K. Recently Issued Accounting Pronouncements Not Yet Effective In November 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2024-03, “Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures” (“ASU 2024-03”), which requires additional disclosure of certain costs and expenses within the notes to the financial statements. ASU 2024-03 will be effective for fiscal years beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact from ASU 2024-03 on its condensed consolidated financial statements disclosures. In September 2025, the FASB issued ASU 2025-06, “Targeted Improvements to the Accounting for Internal-Use Software” (“ASU 2025-06”), which simplifies the capitalization guidance by removing all references to software development project stages so that the guidance is neutral to different software development methods. ASU 2025-06 is effective for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods. Early adoption is permitted. ASU 2025-06 permits an entity to apply the new guidance using a prospective, retrospective or modified transition approach. The Company is currently evaluating the impact from ASU 2025-06 on its condensed consolidated financial statements. In December 2025, the FASB issued ASU 2025-10, “Accounting for Government Grants Received by Business Entities” (“ASU 2025-10”), which establishes the accounting and presentation for government grants received by a business entity. ASU 2025-10 is effective for annual reporting periods beginning after December 15, 2028, and interim reporting periods within those annual reporting periods. Early adoption is permitted. ASU 2025-10 permits an entity to apply the new guidance using a modified prospective basis, a modified retrospective basis or a full retrospective basis. The Company is currently evaluating the impact from ASU 2025-10 on its condensed consolidated financial statements. In December 2025, the FASB issued ASU 2025-12, “Codification Improvements” (“ASU 2025-12”), which addresses various improvements across a wide range of topics in the FASB Accounting Standards Codification to correct, clarify, and otherwise enhance the guidance. ASU 2025-12 is effective for fiscal years beginning after December 15, 2026, including interim reporting periods within those fiscal years. Early adoption is permitted, and the transition method may vary on an issue-by-issue basis. The Company is currently evaluating the impact from ASU 2025-12 on its condensed consolidated financial statements and related disclosures.
