Key Details

• Transaction dates and prices:
  • 2026-08-19: Exercise/conversion of derivative — 1,101,986 shares at $11.50 (acquired); $12,672,839 total.
  • 2026-08-27: Open-market sale — 198,200 shares at $20.15 (disposed); $3,993,730 total.
  • Filing reported the derivative as disposed (conversion) at $0 in the Form 4 line for the derivative instrument.
• Shares owned after transaction: filing does not state total beneficial ownership; net change from these transactions = +903,786 shares.
• Footnote: Goodrich ILMJS LLC is the record holder of the securities. Mr. Goodrich is the managing member with voting and investment discretion; he disclaims beneficial ownership of the LLC’s holdings except for any pecuniary interest.
• Filing timeliness: Form 4 was filed 2026-08-28 for transactions dated 2026-08-19 and 2026-08-27, which is later than the SEC’s typical 2-business-day filing window for Form 4s (the filing appears late).

Context

• This was an option/derivative exercise (code M): Goodrich paid $11.50 per share to convert the derivative into common shares. The subsequent open-market sale of a portion of those shares suggests he did not sell all shares received on exercise; the exercise does not appear to have been a cashless/automatic sale of all shares.
• The shares are held of record by an entity (Goodrich ILMJS LLC) for which he is the managing member; that structure can indicate the holdings are institutional/managed rather than direct individual holdings.
