Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Nature of Operations | 1. Nature of Operations Tigo Energy, Inc. and subsidiaries (together, the “Company”) consists of Tigo Energy, Inc. (“Tigo”), its wholly-owned direct and indirect subsidiaries: Tigo Energy MergeCo, Inc. (f/k/a Tigo Energy, Inc.) (“Legacy Tigo”), Tigo Energy Brasil Ltda., Tigo Energy Philippines Inc., Tigo Energy Israel Ltd., Tigo Energy AI Ltd. (f/k/a Foresight Energy, Ltd. (“fSight”)), Tigo Energy Italy SRL, Tigo Energy Equipment Trading (Suzhou) Co., Ltd. and Tigo Energy Australia Pty Ltd. The Company provides solar and energy storage solutions, including module level power electronics (“MLPE”) designed to maximize the energy output of individual solar modules, delivering more energy, active management, and enhanced safety for utility, commercial, and residential solar arrays. By combining its MLPE and solar optimizer technology with intelligent, cloud-based software capabilities, the Company enables advanced energy monitoring, system diagnostics, and real-time control. These smart hardware and software solutions enhance system performance, lower operating costs, and ensure compliance with safety regulations, including rapid shutdown requirements. In addition to MLPE, the Company develops and manufactures inverters and battery energy storage systems for the residential solar-plus storage market, further expanding its suite of solutions for efficient and reliable energy management. The Company is headquartered in Los Gatos, California, with offices in Europe, Asia, and the Middle East. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”). Any reference in these notes to applicable guidance is meant to refer to GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASU”) promulgated by the Financial Accounting Standards Board (“FASB”). 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. The Company has determined the functional currency of the subsidiaries to be the U.S. dollar. The Company remeasures monetary assets and liabilities of its foreign operations at exchange rates in effect at the balance sheet date and nonmonetary assets and liabilities at their historical exchange rates. Income and expenses are remeasured at the weighted-average exchange rates during the relevant reporting period. These remeasurement gains and losses are recorded in other income, net in the condensed consolidated statements of operations and comprehensive income (loss) and were not material for the three and six months ended June 30, 2026, and 2025. In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all normal and recurring adjustments (which consist primarily of accruals, estimates and assumptions that impact the unaudited condensed consolidated financial statements) considered necessary to present fairly Tigo’s condensed consolidated balance sheet as of June 30, 2026 and its condensed consolidated statements of operations and comprehensive income (loss) and stockholders’ equity for the three and six months ended June 30, 2026, and 2025, and its condensed consolidated statements of cash flows for the six months ended June 30, 2026, and 2025. Operating results for the three and six months ended June 30, 2026, are not necessarily indicative of the results that may be expected for the full year ending December 31, 2026. The unaudited condensed consolidated financial statements, presented herein, do not contain all of the required disclosures under GAAP for annual consolidated financial statements. The condensed consolidated balance sheet as of December 31, 2025, has been derived from the audited consolidated balance sheet as of that date. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our 2025 Annual Report. Reclassification of Prior Period Presentation To conform with current period presentation, $0.3 million of other assets have been reclassified to deferred tax assets on our condensed consolidated balance sheet as of December 31, 2025. Additionally, a de minimis amount of prepaid expenses and other assets has been reclassified to deferred income tax (benefit) expense within operating activities on our condensed consolidated statement of cash flows for the six months ended June 30, 2025. These changes in presentation do not affect previously reported results.
