Change in Certifying Accountants (Form 8-K)

Item 4.01 Change in Registrant's Certifying Accountant.

The Audit Committee of the Board of Directors (the "Audit Committee") of Interparfums, Inc. (the "Company") dismissed Forvis Mazars, LLP ("Forvis") as the Company's independent registered public accounting firm effective May 8, 2026.

The reports of Forvis on the Company's consolidated financial statements as of and 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.

As previously disclosed in the Company's Annual Report on Form 10-K for the fiscal years ended December 31, 2025 and December 31, 2024, management concluded that the Company had not maintained effective internal control over financial reporting as of December 31, 2025 and December 31, 2024. Forvis concurred with management's assessment as disclosed in the Company's Annual Reports on Form 10-K for December 31, 2025 and December 31, 2024.

During the Company's two most recent fiscal years and any subsequent interim period preceding May 8, 2026, there were no disagreements (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) with Forvis on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreement(s), if not resolved to the satisfaction of Forvis, would have caused Forvis to make reference thereto in its reports on the Company consolidated financial statements, and no reportable events of the type listed in paragraphs (A) through (D) of Item 304(a)(1)(v) of Regulation S-K, other than, as previously disclosed in Item 9A of the Company's Annual Report on Form 10-K for the years ended December 31, 2025 and 2024, a material weakness in internal control over financial reporting

On May 8, 2026, the Audit Committee appointed Grant Thornton, LLP ("Grant Thornton") as the Company's independent registered public accounting firm. Commencing with calendar year ended December 31, 2025 through the date of this report, neither the Company nor anyone acting on its behalf consulted Grant Thornton 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 registrant's financial statements or (ii) any matter that was either the subject of a disagreement (as described in Regulation S-K paragraph 304(a)(1)(iv)), or a reportable event (as described in Regulation S-K paragraph 304(a)(1)(v)).
