    • 2026-05-13 — Open-market purchase (code P): 2,000 shares @ $2.82, total $5,640.
    • 2025-11-17 — Award/Grant (code A): 46,534 RSUs @ $0.00 (derivative award).

  • Relevant footnotes:

    • F2: RSU vesting schedule — 512 units vest 6/8/2026 and monthly thereafter through 12/8/2028; 523 units vest 1/8/2029; vesting contingent on continued service.
    • F3: No expiration date for the award.

Context

  • The purchase is a straightforward open-market buy (a direct purchase is generally considered a more informative insider signal than routine grants), while the RSUs are a common form of executive compensation and do not represent immediately tradable shares until they vest.
  • The RSU grant reported at $0.00 is standard for equity awards recorded as derivative grants; actual value is tied to future vesting and the stock price at settlement.
  • No indication of a 10b5-1 plan, cashless exercise, gift, or tax-withholding sale was provided in the filing.
