Insider‑Transaction Compliance Specialist

Notice lists multiple proposed restricted‑share dispositions by a reporting person.

The submission is a regulatory notice of proposed sales in restricted Common Stock across several grant/issue dates, each with a specific share count tied to a listed date. The rows identify individual restricted stock lots dated from 11/16/2022 through 03/10/2026.

These entries are administrative disclosures required for planned dispositions; whether sales are executed, and the cash‑flow treatment, are not stated in the excerpt. Subsequent trade reports or resale filings would show completed transactions.
