Transaction date: 2026-02-11; Form 4 filed 2026-02-13 (within the typical 2‑business‑day reporting window).
RSU grant: 95,122 shares @ $2.05 = $195,000.
PSU grant: 285,366 shares @ $0 (derivative/contingent award — no immediate cash value).
Shares owned after the transaction: not specified in the filing.
Grant plan: awards made under the Issuer’s 2024 Equity Incentive Plan.
Vesting/conditions:
- RSUs: One-third vests on Feb 11, 2027; the remaining two-thirds vest quarterly in equal amounts over the following two years. (Footnote F1)

Context

These are compensation awards, not open-market purchases or sales; RSUs provide future shares as they vest, while PSUs are performance-contingent and carry no immediate tradeable value. Such grants are routine for executives and reflect incentive compensation rather than a direct market buy/sell signal.
