Key Details

• Transaction date: July 10, 2026; Form 4 filed July 14, 2026 (timely within required reporting window).
• Reported acquisition price/value: $0.00 for all listed awards (typical for grants/awards).
• Post-transaction beneficial ownership: not specified in this filing.
• Footnotes/vesting:
  • RSUs (F1, F2): vest on the earlier of July 10, 2027 or the issuer's next Annual Meeting of Stockholders, subject to continued service.
  • Stock options (F3, F4): vest monthly over one year (1/12 per month) but become fully vested on the earlier of the first anniversary of the grant or the next Annual Meeting, subject to continued service.
• These grants are standard non-employee director compensation; no 10b5-1 plan, tax withholding, or sale reported.

Context

• These transactions are awards (not open-market purchases or sales) and are commonly used to compensate directors. RSUs convert to shares when they vest; options give the holder the right to purchase shares later (exercise terms/strike price not disclosed here). Awards like these do not by themselves indicate the director bought or sold shares in the market.
