Investor Verification Checklist

- Monitor future filings (e.g., 10-K or 10-Q) for the first financial statements audited by Deloitte & Touche LLP.
- Review the rationale for the auditor change in subsequent investor communications or earnings calls, as the 8-K does not explicitly state the business reason for the switch.
