Open-market purchases and sales (Form 4 codes P and S) by officers, directors and 10% owners, by transaction date, from 2025-06-13 to 2025-10-11. Excludes option exercises, grants, gifts and tax withholding. Amended filings replace the originals; joint filings count once. Foreign private issuers do not file Form 4. Many insider sales are pre-scheduled (10b5-1 plans) and are not by themselves a sign of wrongdoing.
"As of the Effective Time, Grassi & Co., CPAs, P.C. (" Grassi "), was dismissed as the independent registered public accounting firm of the Company."
Quoted from the filing. Source
The company changed its outside auditor (8-K Item 4.01). A dismissal or resignation, especially near an annual report or with reported disagreements, is a warning sign. Changes caused by audit firms merging are usually routine.
Type: routine (post-merger auditor consolidation)
Disagreements reported: no
Former auditor: Grassi & Co., CPAs, P.C.
Why this score: routine: auditor replaced after company merger/SPAC deal; also within 90 days: Going-concern doubt
