Item
4.01. Changes in Registrant’s Certifying Accountant.
(a)
Resignation of Independent Registered Public Accounting Firm.
On
June 3, 2026, we were notified that Assure CPA, LLC (“Assure”), which served as the independent registered public accounting
firm of Flexible Solutions International, Inc. (the “Company”), merged into Sadler, Gibb & Associates, LLC. (“Sadler
Gibb”) pursuant to an asset purchase agreement. As a result of the transaction, Assure ceased operations as a public accounting
firm and resigned as the Company’s independent registered public accounting firm.
The
resignation of Assure and the engagement of Sadler Gibb described in paragraph (b) below were approved by the Audit Committee of the
Company’s Board of Directors on June 5, 2026.
Assure’s
audit reports on the Company’s consolidated financial statements for the fiscal years ended December 31, 2025 and 2024 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.
During
the fiscal years ended December 31, 2025 and 2024 and the subsequent interim period through June 3, 2026, there were (i) no disagreements
(within the meaning of Item 304(a)(1)(iv) of Regulation S-K and the related instructions) with Assure on any matter of accounting principles
or practices, financial statement disclosure, or auditing scope or procedures which, if not resolved to Assure’s satisfaction,
would have caused Assure to make reference to the matter in its reports, and (ii) no “reportable events” within the meaning
of Item 304(a)(1)(v) of Regulation S-K.
The
Company has provided Assure with a copy of this Current Report on Form 8-K and has requested that Assure furnish a letter addressed to
the Securities and Exchange Commission stating whether it agrees with the statements made by the Company herein. A copy of Assure’s
letter, dated June 5, 2026, is filed as Exhibit 16.1 to this report.
(b)
Engagement of New Independent Registered Public Accounting Firm.
On
June 5, 2026, the Company’s Audit Committee approved the engagement of Sadler Gibb as the Company’s independent registered
public accounting firm for the fiscal year ending December 31, 2026.
During
the fiscal years ended December 31, 2025 and 2024 and the subsequent interim period through June 5, 2026, neither the Company nor anyone
on its behalf consulted with Sadler Gibb 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 financial statements, and no written
report or oral advice was provided to the Company that Sadler Gibb 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) and the related instructions) or a reportable event (as described in Item 304(a)(1)(v)).
