Item 4.01 Changes in Registrant’s Certifying Accountant.
On April 1, 2026, the Audit Committee of the Board of Directors of Instil Bio, Inc. (the “Company”) approved the appointment of RSM US LLP (“RSM”) as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2026. This action resulted in the replacement of Deloitte & Touche LLP (“Deloitte”) as the Company’s independent registered public accounting firm, which the Audit Committee dismissed effective April 1, 2026.
The reports of Deloitte on the Company’s consolidated financial statements for the fiscal years ended December 31, 2025 and 2024 did not contain an adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles. In connection with the audits of the Company's consolidated financial statements for the fiscal years ended December 31, 2025 and 2024, and in the subsequent period through April 1, 2026, there were no disagreements with Deloitte on any matters of accounting principles or practices, financial statement disclosure or auditing scope and procedures which, if not resolved to the satisfaction of Deloitte, would have caused Deloitte to make reference to the matter in their report. There were no reportable events (as that term is described in Item 304(a)(1)(v) of Regulation S-K) during the fiscal years ended December 31, 2025 and 2024, or in the subsequent period through April 1, 2026.
The Company has provided a copy of the foregoing disclosures to Deloitte and requested that Deloitte furnish it with a letter addressed to the Securities and Exchange Commission stating whether Deloitte agrees with the above statements. A copy of Deloitte’s letter, dated April 3, 2026, is filed as Exhibit 16.1 to this Form 8-K.
During the two most recent fiscal years and in the subsequent interim period through April 1, 2026, neither the Company nor anyone on its behalf has consulted with RSM with respect to the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that would have been rendered on the Company’s consolidated financial statements, or any other matters set forth in Item 304(a)(2)(i) or (ii) of Regulation S-K.
