[6-K] Infobird Co., Ltd Current Report (Foreign Issuer)

Rhea-AI Filing Summary

Infobird Co., Ltd reported that it dismissed Audit Alliance LLP as its independent registered public accounting firm, effective January 16, 2026, with the decision approved by its board of directors. Audit Alliance’s audit reports on the company’s financial statements for the years ended December 31, 2024 and 2023 did not contain adverse or disclaimed opinions, but they did express doubt about Infobird’s ability to continue as a going concern.

The company stated there were no disagreements with Audit Alliance on accounting principles, financial statement disclosure, or audit procedures during the last two fiscal years and up to January 16, 2026, and no reportable events as defined in Form 20-F. Infobird has appointed Assentsure PAC as its new independent registered public accounting firm, also effective January 16, 2026, to audit the consolidated financial statements for the year ended December 31, 2025, with the appointment approved by the board and audit committee.

Insights

Equity analyst – governance and reporting

Infobird changes auditors with prior going concern emphasis but no stated disputes.

Infobird has replaced Audit Alliance LLP with Assentsure PAC as its independent registered public accounting firm, effective January 16, 2026. The new firm will audit the company’s consolidated financial statements for the year ended December 31, 2025, with approval from both the board and the audit committee. Auditor changes can be sensitive, but here the company emphasizes formal approvals and continuity of audited reporting.

Audit Alliance’s reports for the years ended December 31, 2024 and 2023 included an expression of doubt about Infobird’s ability to continue as a going concern. That language points to previously disclosed financial strain, though the filing does not add new financial data. Infobird states there were no disagreements or reportable events with Audit Alliance, and the former auditor’s letter confirms agreement with the statements pertaining to it, which helps reduce concerns that the change stems from a disclosed dispute.

Changes in Registrant’s Certifying Accountant

Discontinuation of the Services from the Company’s Independent Registered Public Accounting Firm  

Infobird Co., Ltd. (the “Company”) is furnishing this current report on Form 6-K to report the dismissal of Audit Alliance LLP (“Audit Alliance”), effective January 16, 2026. The dismissal of Audit Alliance has been considered and approved by the board of directors (the “Board”) of the Company.

Audit Alliance’s reports on the Company’s financial statements for the fiscal years ended December 31, 2024 and 2023 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 such reports expressed doubt regarding the Company’s ability to continue as a going concern. Furthermore, during the Company’s two most recent fiscal years and through January 16, 2026, there have been no disagreements with Audit Alliance on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to Audit Alliance’s satisfaction, would have caused Audit Alliance to make reference to the subject matter of any such disagreements in connection with its reports on the Company’s financial statements for such periods.

For the fiscal years ended December 31, 2024 and 2023 and through January 16, 2026, there were no “reportable events” as that term is described in Item 16F(a)(1)(v) of the Form 20-F.

The Company provided Audit Alliance with a copy of the above disclosure and requested that Audit Alliance furnish the Company with a letter addressed to the U.S. Securities and Exchange Commission stating whether or not it agrees with the above statement. A copy of Audit Alliance’s letter is filed as Exhibit 16.1 to this Form 6-K.

Appointment of New Independent Registered Public Accounting Firm  

The Company has appointed Assentsure PAC (“Assentsure”) as successor auditor of the Company effective January 16, 2026 to audit the Company’s consolidated financial statements as of and for the fiscal year ended December 31, 2025.   The appointment of Assentsure has been approved by the Board and the audit committee.

During the Company’s most two recent fiscal years and through January 16, 2026  , neither the Company nor anyone acting on the Company’s behalf consulted Assentsure with respect to any of the matters or reportable events set forth in Item 16F(a)(2)(i) and (ii) of the Form 20-F.
