Open-market purchases and sales (Form 4 codes P and S) by officers, directors and 10% owners, by transaction date, from 2025-09-11 to 2026-01-09. 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

"Grant Thornton was previously engaged to audit the Company's consolidated financial statements for the year ending December 31, 2025."

Type: dismissed
Disagreements reported: no
Former auditor: Grant Thornton LLP · New auditor: Deloitte & Touche LLP
