Item 4.01. Changes in Registrant’s Certifying Accountant.

(a) On April 1, 2026, Kestrel Group Ltd (the “Company”), through action of the Audit Committee of the Board of Directors of the Company (the “Audit Committee”), approved the dismissal of Ernst & Young LLP (“EY”) as the Company’s independent registered public accounting firm, effective immediately.

The report of EY on the Company’s consolidated financial statements for the fiscal year ended December 31, 2025, did not contain an adverse opinion or disclaimer of opinion and was not qualified or modified as to uncertainty, audit scope, or accounting principles.

During the fiscal year ended December 31, 2025 and the subsequent interim period through the date of dismissal, (i) there were no disagreements (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) between the Company and EY on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to EY’s satisfaction, would have caused EY to make reference to the subject matter of the disagreements in its report on the Company’s consolidated financial statements for such year and (ii) there have been no reportable events (as defined in Item 304(a)(1)(v) of Regulation S-K).

The Company provided EY with a copy of this Current Report on Form 8-K prior to filing with the Securities and Exchange Commission (“SEC”) and requested that EY furnish a letter addressed to the SEC stating whether or not it agrees with the statements made by the Company. A copy of EY’s letter, dated April 6, 2026 is filed as Exhibit 16.1 to this Current Report on Form 8-K.

(b) On April 1, 2026, the Company, through action of the Audit Committee, approved the engagement of Grant Thornton LLP (“Grant Thornton”) as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2026.

During the fiscal year ended December 31, 2025 and the subsequent interim period prior to engagement, neither the Company nor anyone on its behalf consulted with Grant Thornton regarding: (a) the application of accounting principles to a specified 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 by Grant Thornton that Grant Thornton concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issue; or (b) 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) or a reportable event (as defined in Item 304(a)(1)(v) of Regulation S-K).
