On April 17, 2026, the Audit Committee of the Board of Directors of the Company (the “Audit Committee”) approved the dismissal of Withum Smith+Brown, PC (“Withum”) as the Company’s independent registered public accounting firm.

Withum’s report of independent registered public accounting firm on the Company’s balance sheet as of September 18, 2025 and the related statements of operations, changes in stockholders’ equity and cash flows for the period from August 29, 2025 (inception) through September 18, 2025, did not contain an adverse opinion or a disclaimer of opinion, and were not qualified or modified as to uncertainties, audit scope or accounting principles, except that the audit report on the consolidated financial statements contained an explanatory paragraph in which WithumSmith+Brown expressed substantial doubt about the Company’s ability to continue as a going concern.

During the period from August 29, 2025 (inception) to December 31, 2025, and during the subsequent interim period through April 17, 2026, there were no disagreements with Withum on any matter of accounting principles or practices, financial disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Withum, would have caused it to make reference to the subject matter of the disagreements in its reports on the Company’s financial statements for such period.

During period from August 29, 2025 (inception) to September 18, 2025, and during the subsequent interim period through April 17, 2026, there have been no reportable events as listed in paragraphs (a)(1)(v)(A) through (a)(1)(v)(D) of Item 16F of Form 20-F.

The Company has provided Withum with a copy of the foregoing disclosures and requested that Withum furnish the Company with a letter addressed to the SEC stating whether Withum agrees with the statements made by the Company set forth above. A copy of Withum’s letter, dated April 21, 2025, is attached as Exhibit 16.1 to this Current Report on Form 6-K.
