Insights

Auditor switch follows disclosed internal control weakness but without reported disputes.

Interparfums, Inc. replaced Forvis Mazars, LLP with Grant Thornton, LLP as its independent registered public accounting firm effective May 8, 2026. Forvis’ prior reports on the 2025 and 2024 financial statements were clean, without adverse opinions or scope or principle qualifications.

The company and Forvis both acknowledged a material weakness in internal control over financial reporting as of December 31, 2025 and December 31, 2024. The filing notes no disagreements or additional reportable events beyond this weakness, indicating the change was not attributed to disputes over accounting treatment in this disclosure.

Auditor transitions during a period of internal control remediation can draw investor attention because the new firm must assess controls and financial reporting for future periods. Subsequent company filings may outline how Grant Thornton evaluates the existing weakness and any steps taken to strengthen internal controls.

independent registered public accounting firm regulatory

"dismissed Forvis Mazars, LLP as the Company’s independent registered public accounting firm"

An independent registered public accounting firm is an outside accounting company officially registered with the government regulator to examine and report on a public company's financial records and controls. Investors treat its reports like an impartial inspector’s certificate — they add credibility to financial statements, help spot errors or misleading claims, and reduce the risk that shareholders are relying on unchecked or biased numbers.

material weakness in internal control over financial reporting financial

"a material weakness in internal control over financial reporting"

reportable events regulatory

"no reportable events of the type listed in paragraphs (A) through (D)"

Reportable events are significant incidents or changes a company is legally required to disclose to regulators and the public, such as major safety problems, legal actions, financial irregularities, or management changes. They matter to investors because these events can alter a company’s risk profile or future performance, much like a dashboard warning light signals a problem that could affect a car’s safety or reliability. Timely disclosure helps investors make informed decisions and maintain market fairness.

Regulation S-K regulatory

"as defined in Item 304(a)(1)(iv) of Regulation S-K"

A set of U.S. Securities and Exchange Commission rules that tell public companies which narrative and qualitative details must be disclosed in filings, such as risk factors, management discussion, executive pay, legal proceedings and business description. Think of it as a standardized checklist or blueprint that ensures investors get the same types of background information from every company so they can compare risks, management quality and strategy before making investment decisions.

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)).
