2025-11-03: red flag filed

Open-market purchases and sales (Form 4 codes P and S) by officers, directors and 10% owners, by transaction date, from 2025-08-05 to 2025-12-03. 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

"Following an extensive evaluation process, the Audit Committee chose KPMG. GT was previously engaged to audit the Company's consolidated financial statements for the year ending December 31, 2025."

Quoted from the filing. Source

What this means

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: changed
Disagreements reported: no
New auditor: KPMG LLP
