Change of Auditor

On February 25, 2026, SOS Limited (the “Company”), upon the approval and ratification of the audit committee of the board of directors (the “Audit Committee”), dismissed Audit Alliance LLP (“Audit Alliance”), the former independent registered public accounting firm of the Company, effective on February 25, 2026, and appointed Assentsure PAC (PCAOB ID: 6783) (“Assentsure PAC”) to serve as its independent registered public accounting firm, effective on February 25, 2026, for the year ended December 31, 2025.

Audit Alliance’s reports on the Company’s financial statements for the fiscal years ended December 31, 2024, 2023 and 2022 did not contain any adverse opinion or disclaimers of opinion and were not qualified or modified as to uncertainty, audit scope, or accounting principles. Furthermore, during the Company’s most recent fiscal year, there were 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 the satisfaction of Audit Alliance, would have caused Audit Alliance to make reference to the subject matter of the disagreements in connection with its reports on the Company’s financial statements for such year. Also, during this time, there were no “reportable events,” as defined in Item 304(a)(1)(v) of Regulation S-K.

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 statements. A copy of Audit Alliance’s letter is furnished as Exhibit 16.1 to this Form 6-K.

During the two most recent fiscal years and any subsequent interim periods prior to the engagement of Assentsure PAC, neither the Company, nor someone on behalf of the Company, has consulted Assentsure PAC regarding (i) the application of accounting principles to any 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 Assentsure PAC 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 either the subject of a “disagreement,” as defined in Item 304(a)(1)(iv) of Regulation S-K, or a “reportable event,” as defined in Item 304(a)(1)(v) of Regulation S-K, or any other matters set forth in Item 304(a)(2)(i) and (ii) of Regulation S-K.
