Sentinel Holdings Ltd. 8-K

What Happened Sentinel Holdings Ltd. (SNTL) filed an 8-K on June 11, 2026 reporting that its Board approved the dismissal of its independent registered public accounting firm, Bush & Associates CPA LLC. The dismissal was approved on June 9, 2026 and became effective June 10, 2026, after completion of the audit for the year ended December 31, 2025. Bush & Associates’ audit reports for the fiscal years ended December 31, 2025 and 2024 included a “going concern” qualification but did not contain an adverse opinion or a disclaimer. The company requested a letter from Bush & Associates confirming the statements in the 8-K (attached as Exhibit 16.1).
The Board also appointed DiPiazza LaRocca Heeter & Co., LLC (DLHC) as the new independent registered public accounting firm, effective beginning with the review of Sentinel’s condensed consolidated financial statements for the quarter ended March 31, 2026.

Key Details

• Dismissal approved June 9, 2026; effective June 10, 2026 (Bush & Associates).
• Prior audit reports (fiscal years 2024 and 2025) included a “going concern” qualification but no adverse opinion, no disclaimer, and no qualifications for scope or accounting principles.
• No “disagreements” or “reportable events” with Bush & Associates were identified for 2024 or 2025. Company provided the accountant a copy of the 8-K disclosures on June 10 and requested a confirming letter (Exhibit 16.1).
• New auditor DLHC appointed June 9, 2026 to begin with the March 31, 2026 quarter review; DLHC had no prior consultations with the company during 2024, 2025 or the interim through June 9, 2026.

Why It Matters A change in the independent auditor is material because the auditor provides assurance about the company’s financial statements. The prior auditor’s “going concern” qualification signals that the auditor had substantial doubt about Sentinel’s ability to continue as a going concern — a condition investors should monitor in future filings. The 8-K notes there were no disagreements with the prior auditor and no reportable events, and a new auditor is in place to perform 2026 reviews, so investors should watch upcoming quarterly filings for any updates to audit opinions, disclosures about liquidity or operations, and management’s plans to address going-concern risks.
