Open-market purchases and sales (Form 4 codes P and S) by officers, directors and 10% owners, by transaction date, from 2025-04-16 to 2025-08-14. 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.
"Grant Thornton LLP was appointed as the auditor of record of the Company on April 15, 2025, and did not issue an audit report on the consolidated financial statements of the Company as of any date or for any period."
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.
