Any reference in these notes to applicable guidance is meant to refer to U.S. GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASU”) of the Financial Accounting Standards Board (the “FASB”). The accompanying unaudited condensed consolidated financial statements include the accounts of Interactive Strength Inc. and its subsidiaries in which the Company has a controlling financial interest, and should be read in conjunction with the annual audited consolidated financial statements and notes thereto as of and for the year ended December 31, 2025 included in the Company’s Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 31, 2026. The accompanying consolidated balance sheet as of December 31, 2025 was derived from the audited financial statements as of and for the year ended December 31, 2025. These condensed consolidated interim financial statements have been prepared in accordance with the instructions to Form 10-Q and Article 8 of Regulation S-X, and therefore omit or condense certain footnotes and other information normally included in complete consolidated financial statements prepared in accordance with U.S. GAAP. All intercompany balances and transactions have been eliminated in consolidation. 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 financial statements) considered necessary to present fairly the Company’s financial position as of March 31, 2026 and its results of operations, comprehensive loss, changes in stockholders’ equity and cash flows for the three months ended March 31, 2026 and 2025. In addition, certain prior year balances have been reclassified to conform to the current presentation. Specifically, Income tax payable as of December 31, 2025 in the amount of $7,000 has been reclassified to Accrued expenses and other current liabilities in the accompanying condensed consolidated balance sheet and Proceeds from exercise of incremental warrants and issuance of convertible notes, net of issuance costs for the three months ended March 31, 2025 in the amount of $3.5 million has been reclassified to Proceeds from issuance of convertible notes, net of issuance costs, in the accompanying condensed consolidated statement of cash flows. The financial data and other information disclosed in these notes related to the three months ended March 31, 2026 and 2025 are unaudited. The results for the three months ended March 31, 2026 and 2025 , are not necessarily indicative of results to be expected for the year ending December 31, 2026 , any other interim periods, or any future year or period. Use of Estimates The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue, expenses, and related disclosures. On an ongoing basis, the Company evaluates its estimates, including, among others, those related to the realizability of inventory, fair value measurements, useful lives of long lived assets, including property and equipment and finite lived intangible assets, product warranty, stock-based compensation expense, warrant liabilities, accrual of acquisition earn-outs, valuation of deferred taxes, valuation of derivatives, fair value of goodwill and other intangible assets, fair value of preferred stock in connection with acquisitions and debt extinguishments, and commitments and contingencies. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable. Actual results may differ from these estimates. Segment Information Operating segments are defined as components of an enterprise for which separate and discrete information is available for evaluation by the chief operating decision-maker (“CODM”) in deciding how to allocate resources and assess performance. The Company has one operating segment, the development and sale of its at-home fitness technology platform. The Company’s CODM is its chief executive officer, who manages the Company’s operations on a consolidated basis for the purpose of allocating resources. As the Company has one reportable segment, all required segment financial information is presented in the consolidated financial statements (See Note 3). The Company currently operates in the United States, the United Kingdom, and Taiwan. As of March 31, 2026 and December 31, 2025, substantially all of the Company's long-lived assets were held in the United States. Significant Accounting Policies During the three months ended March 31, 2026, there were no significant changes to the Company’s significant accounting policies as described in the Company’s audited consolidated financial statements as of and for the year ended December 31, 2025, except as described below. Loan Receivable Loan receivable as of December 31, 2025 consisted of a loan agreement entered into with Sportstech Brands Holding GmbH ("Sportstech") and Mr. Ali Ahmad, the sole shareholder of Sportstech, which was intended as a form of bridge financing until a pending acquisition transaction could be closed. The Transaction did not close as the Company and Sportstech were unable to come to terms on a final subscription and shareholders' agreement, and the loan was not paid back at the maturity date of December 30, 2025. The balance on the loan receivable from Sportstech as of December 31, 2025, including accrued interest and fees, was $6.6 million, which was recorded on the Company's balance sheet as of December 31, 2025. On March 4, 2026, the Company and Sportstech settled the outstanding balance and the Company received $6.4 million in cash. As a result, the Company recorded a credit loss on the settlement of the loan receivable in the amount of $0.2 million in the first quarter of 2026, which is reflected in Other expense in the accompanying condensed consolidated statement of operations. Recently Issued Accounting Pronouncements From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”), or other standard setting bodies and adopted by the Company as of the specified effective date. Unless otherwise discussed, the impact of recently issued standards that are not yet effective will not have a material impact on the Company’s condensed consolidated financial statements upon adoption. The Company qualifies as an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) and has elected not to “opt out” of the extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company has the option to adopt the new or revised standard at the time private companies adopt the new or revised standard and may do so until such time that the Company either (i) irrevocably elects to “opt out” of such extended transition period or (ii) no longer qualifies as an emerging growth company. As noted below, certain new or revised accounting standards were early adopted. Accounting Pronouncements Recently Adopted ASU 2025-05 In July 2025, the FASB issued ASU 2025-05, “Financial Instruments – Credit Losses (Topic 326).” In developing forecasts as part of estimating expected credit losses, the ASU allows entities to elect a practical expedient that assumes that current conditions as of the balance sheet date do not change for the remaining life of the asset. This ASU is effective for annual and interim periods beginning in 2026. The Company adopted ASU 2025-05 effective January 1, 2026. Adoption of the new standard did not have a material impact on the Company's consolidated financial statements. Accounting Pronouncements Not Yet Adopted ASU 2024-03 In November 2024, the FASB issued ASU 2024-03, as amended by ASU 2025-01, "Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses". The amendments in ASU 2024-03 address investor requests for more detailed expense information and require additional disaggregated disclosures in the notes to financial statements for certain categories of expenses that are included on the face of the income statement. This guidance is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating this guidance to determine the impact it may have on its condensed consolidated financial statements. ASU 2025-06 In September 2025, the FASB issued ASU 2025-06, “Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40).” The ASU updates the guidance on accounting for internal-use software costs by (i) removing all references to software development stages, and (ii) requiring that an entity capitalize software costs when both management has authorized and committed to funding the software project, and it is probable that the project will be completed and the software will be used to perform the function intended. This ASU is effective for annual and interim periods beginning in 2028. Early adoption is permitted. The Company is currently evaluating the impact of the new standard.
