Open-market purchases and sales (Form 4 codes P and S) by officers, directors and 10% owners, by transaction date, from 2026-01-31 to 2026-05-31. 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.

Verified excerpt

"Accordingly, the Audit Committee of the Board concluded that Management's Report on Internal Control over Financial Reporting as of December 31, 2025 should no longer be relied upon."

Quoted from the filing. Source

What this means

The company says previously issued financial statements should no longer be relied upon (8-K Item 4.02). This is one of the most serious accounting red flags: past reported numbers were wrong and will be restated.
