FLEXIBLE SOLUTIONS INTERNATIONAL INC 8-K

What Happened

• Flexible Solutions International, Inc. (FSI) notified on June 3, 2026 that its independent auditor Assure CPA, LLC merged into Sadler, Gibb & Associates, LLC and ceased operations as a public accounting firm. As a result, Assure resigned as FSI’s independent registered public accounting firm.
• The company’s Audit Committee approved both Assure’s resignation and the engagement of Sadler Gibb on June 5, 2026. Sadler Gibb was engaged as FSI’s independent registered public accounting firm for the fiscal year ending December 31, 2026.
• Assure’s audit reports for the fiscal years ended December 31, 2025 and 2024 were unqualified (no adverse opinion, disclaimer, or modifications), and there were no disagreements or “reportable events” between the company and Assure for those periods. A letter from Assure dated June 5, 2026 is filed as Exhibit 16.1.

Key Details

• Date of notice: June 3, 2026 (Assure merger into Sadler Gibb and cessation of operations).
• Audit Committee approval and new engagement date: June 5, 2026 (Sadler Gibb engaged for FY 2026).
• Prior audits: Assure’s reports for FYs ended Dec 31, 2025 and 2024 were unqualified; no disagreements or reportable events.
• No consultations with Sadler Gibb on accounting or auditing matters during FYs 2025, 2024 or the interim period through June 5, 2026.

Why It Matters

• Auditor changes can matter to investors because they affect who reviews and signs off on the company’s financial statements. In this case the change resulted from Assure CPA’s merger and resignation — not from any dispute or audit issue.
• The filing indicates continuity and no identified problems: prior years’ audits were unqualified and there were no disagreements or reportable events. Investors should view this as an administrative change, while monitoring future filings for any material audit-related disclosures (e.g., changes in audit scope, fees, or opinions) once Sadler Gibb begins auditing the 2026 year.
