Change in Independent Registered Public Accounting Firm

On October 16, 2026, the audit committee (the “Audit Committee”) of the board of directors (the “Board”) of Neo-Concept International Group Holdings Ltd (the “Company”) approved the dismissal of WWC, P.C. (“WWC”) as the Company’s independent registered public accounting firm, and the Board approved such dismissal, in each case effective October 16, 2026.

The audit reports of WWC on the Company’s consolidated financial statements as of and for the fiscal years ended December 31, 2024 and 2025 did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope, or accounting principles.

During the fiscal years ended December 31, 2024 and 2025, there were (i) no disagreements (as described in Item 16F(a)(1)(iv) of Form 20-F and the related instructions thereto) between the Company and WWC on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of WWC, would have caused WWC to make reference to the subject matter thereof in its audit reports, and (ii) no reportable events (as described in Item 16F(a)(1)(v) of Form 20-F).

The Company has provided WWC with a copy of the foregoing disclosures and has requested that WWC furnish the Company with a letter addressed to the U.S. Securities and Exchange Commission stating whether it agrees with the statements made by the Company set forth above. A copy of WWC’s letter, dated October 16, 2026, is filed as Exhibit 16.1 to this Report on Form 6-K.

On October 16, 2026, the Audit Committee approved the appointment of Privatco CPA Limited (“PRIVATCO”) as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2026, and the Board approved such appointment, in each case effective October 16, 2026.

During the fiscal years ended December 31, 2024 and 2025, neither the Company nor anyone acting on its behalf has consulted PRIVATCO with respect to (i) 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 consolidated financial statements, and neither a written report nor oral advice was provided to the Company that PRIVATCO concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issue, or (ii) any matter that was the subject of a disagreement (as described in Item 16F(a)(1)(iv) of Form 20-F and the related instructions thereto) or a reportable event (as described in Item 16F(a)(1)(v) of Form 20-F).
