SOLITARIO RESOURCES CORP. 8-K

What Happened Solitario Resources Corp. (XPL) filed an 8-K reporting that Assure CPA, LLC merged into Sadler, Gibb & Associates, causing Assure to cease operations and resign as Solitario’s independent registered public accounting firm. Solitario’s Audit Committee approved Assure’s resignation and appointed Sadler as the company’s independent registered public accounting firm on June 3, 2026. The change resulted from the asset purchase/merger of Assure into Sadler.

Key Details

• Assure notified Solitario of the merger into Sadler on June 2, 2026; the Audit Committee approved the change on June 3, 2026.
• Assure’s audit reports for the years ended December 31, 2025 and 2024 were unmodified (no adverse opinion, disclaimer, or qualification).
• During 2024–2025 and through the interim period before the resignation, there were no disagreements or reportable events between Solitario and Assure.
• Solitario states it did not consult with Sadler, before appointment, on accounting or auditing matters for the periods covered.

Why It Matters A change in independent auditor is material information for investors because auditors provide assurance on the company’s financial statements. In this case, the change was driven by Assure’s merger into Sadler rather than by disputes or accounting problems: Assure’s past audit opinions were unmodified and Solitario reports no disagreements or reportable events. Investors should note the effective auditor change date (June 3, 2026) and watch for future filings audited by Sadler for any differences in audit approach or disclosures.
