Item 4.01 Changes in Registrant’s Certifying Accountant.

(a) Dismissal of Independent Registered Public Accounting Firm

On June 26, 2026, the Audit Committee of the Board of Directors (the “Audit Committee”) of Interactive Strength Inc. (the "Company") dismissed Deloitte & Touche LLP (“Deloitte”) as the Company’s independent registered public accounting firm.

Deloitte’s audit reports on the Company’s consolidated financial statements for the fiscal years ended December 31, 2025 and 2024 did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope, or accounting principles, except that the reports included an explanatory paragraph relating to substantial doubt about the Company’s ability to continue as a going concern.

During the Company’s two most recent fiscal years, which ended on December 31, 2025 and 2024, and the subsequent interim period through June 26, 2026, there were no “disagreements” (within the meaning set forth in Item 304(a)(1)(iv) of Regulation S-K) between the Company and Deloitte on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to Deloitte’s satisfaction, would have caused Deloitte to make reference to the subject matter of disagreements in connection with their reports on the Company's consolidated financial statements for the years ended December 31, 2025 and 2024.

Except as noted in the following paragraph, there were no “reportable events” (within the meaning set forth in Item 304(a)(1)(v) of Regulation S-K) during the Company’s two most recent fiscal years and the subsequent interim period through June 26, 2026.

As disclosed in Part II, Item 9A of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024, the Company identified material weaknesses in its internal control over financial reporting related to (i) a lack of appropriate policies and resources to develop and operate effective internal control over financial reporting and (ii) a lack of formalized internal controls and segregation of duties surrounding the financial transactions. As further disclosed in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025, the material weakness remained unremediated as of December 31, 2025. Specifically, deficiencies persisted regarding the effective control environment and control activities, formal risk assessment, adequateness of processes and controls for communicating information among relevant parties, and appropriate selection, development and performance of monitoring activities.

The Audit Committee has discussed the subject matter of these reportable events with Deloitte. The Company has authorized Deloitte to respond fully to the inquiries of the successor independent registered public accounting firm concerning the subject matter of the reportable events.

In accordance with Item 304(a)(3) of Regulation S-K, the Company provided Deloitte with a copy of this Current Report on Form 8-K and requested that Deloitte furnish it with a letter addressed to the United States Securities and Exchange Commission stating whether Deloitte agrees with the above statements of the Company herein and, if not, stating the respects in which it does not agree. Deloitte furnished the requested letter, and a copy is filed as Exhibit 16.1 to this Current Report on Form 8-K.

(b) Engagement of New Independent Registered Public Accounting Firm

On June 26, 2026, the Audit Committee approved the engagement of Cherry Bekaert LLP (“Cherry Bekaert”) as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2026. During the Company’s two most recent fiscal years and the subsequent interim period through June 26, 2026, neither the Company, nor anyone on its behalf, consulted Cherry Bekaert regarding (i) the application of accounting principles to a specific transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s financial statements, and neither a written report nor oral advice was provided to the Company that Cherry Bekaert concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing, or financial reporting issue, (ii) any matter that was the subject of a disagreement within the meaning of Item 304(a)(1)(iv) of Regulation S-K, or (iii) any matter that was either the subject of a disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of Regulation S-K) or a reportable event of the type described in Item 304(a)(1)(v) of Regulation S-K.
