Open-market purchases and sales (Form 4 codes P and S) by officers, directors and 10% owners, by transaction date, from 2026-04-11 to 2026-08-09. 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.
"Following the expiration of the engagement with YCM CPA INC. ("YCM"), the Company's independent registered public accounting firm, on July 9, 2026, the Company dismissed YCM as the Company's independent registered public accounting firm."
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: dismissed
Disagreements reported: no
Former auditor: YCM CPA INC.
