Context
This transaction reflects a compensation award (one-time bonus for services for the year ended Dec 31, 2025) and routine tax withholding — not an open-market buy or sell. For retail investors, compensation awards indicate company-paid equity to executives but do not necessarily signal personal buying or selling intent. Consult the amended Form 4 for the updated total beneficial ownership after these transactions.
