Rhea-AI Filing Summary

Insights

Sequans formalizes an auditor change with standard no‑disagreement and ICFR context.

The company describes a change in its certifying accountant and emphasizes that neither it nor its representatives consulted Forvis Mazars S.A. on specific accounting treatments or audit opinions for 2024 and 2025. It also states there were no disagreements or reportable events with the former auditor as defined under Form 20‑F.

Ernst & Young Audit confirms agreement with key portions of the disclosure and highlights that a material weakness in internal control over financial reporting, already disclosed in the 2024 and 2025 annual reports, was factored into its audit procedures. This filing mainly documents compliance steps around the auditor transition rather than introducing new financial results, so the immediate impact on valuation is limited.

"FORM 6-K Report of Foreign Private Issuer Pursuant to Rule 13a-16..."
A foreign private issuer is a company organized outside the United States that meets tests showing it is primarily foreign-controlled and therefore qualifies for a different set of U.S. reporting rules. For investors, that means the company files less frequent or differently formatted disclosures with U.S. regulators and may follow home-country accounting and governance practices, so buying its stock is like dining at a well-reviewed restaurant that follows its home kitchen’s rules instead of the local menu — you get access but should check what standards apply.
Form 20-F regulatory
"as disclosed in Item 15.B of the Company’s 2024 Annual Report on Form 20-F..."
Form 20-F is the standardized annual disclosure that non-U.S. companies must file with the U.S. securities regulator when their shares are traded in the U.S.; it contains audited financial statements, a plain-language description of the business, management discussion, governance details and key risk factors. It matters to investors because it provides a consistent, comparable company “report card” and rulebook, helping buyers assess financial health, governance and risks before investing.

Item 1. Change in Registrant's Certifying Accountant

At the Meeting in the Ninth Resolution, the shareholders approved the appointment of Forvis Mazars S.A. as the Company's independent public accounting firm for the fiscal years ending December 31, 2026 to December 31, 2031, with the mandate expiring with the annual shareholders' meeting in 2032. The six-year mandate is required by French law. Forvis Mazars S.A. replaces Ernst & Young Audit, whose term concluded effective June 30, 2026. The decision to change auditors was approved by the Audit Committee.

Regarding the Outgoing Auditor — Ernst & Young Audit:

The audit reports of Ernst & Young Audit on the Company's consolidated financial statements for each of the fiscal years ended December 31, 2024 and 2025 did not contain an adverse opinion or a disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope, or accounting principles, except that the report
for the inclusion of year ended December 31, 2025 included an explanatory paragraph on the Company’s ability to continue as a going concern.

As defined in Item 16F(a)(1)(v) of the Instructions to Form 20-F, during the fiscal years ended December 31, 2024 and 2025, and through the effective date of the change, there were no disagreements between the Company and Ernst & Young Audit on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which, if not resolved to the satisfaction of Ernst & Young Audit, would have caused Ernst & Young Audit to make reference to the subject matter of the disagreement in connection with its reports.

As defined in Item 16F(a)(1)(v) of the Instructions to Form 20-F, there were no "reportable events", except as it relates to the identification of material weaknesses in internal control over financial reporting as disclosed in Item 15.B of the Company's 2025 Annual Report on Form 20-F.

Regarding the Incoming Auditor —Forvis Mazars S.A.:

During the fiscal years ended December 31, 2024 and 2025, and through the date hereof, neither the Company nor anyone acting on its behalf consulted Forvis Mazars S.A. regarding:

(i)either 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 was provided to the Company, nor oral advice was provided, that Forvis Mazars S.A. concluded was an important factor considered by the Company in reaching a decision as to the accounting, auditing or financial reporting issue;
(ii)or any matter that was the subject of a disagreement (as described in Item 16F(a)(1)(iv) of the Instructions to Form 20-F and the related instructions to this Item) or reportable event (as described in Item 16F(a)(1)(iv) of the Instructions to Form 20-F and the related instructions to this Item).

The Company has provided Ernst & Young Audit with a copy of the foregoing disclosures. A letter from Ernst & Young Audit stating whether it agrees with the statements made herein is attached hereto as Exhibit 99.1.
