Filing context
- Quantities and prices are shown in the units filed. No trade value is inferred from their product.
- Horstman Marc: President and COO.
- F1: On November 4, 2026, the Issuer's board of directors approved an amendment to the stock option granted to the reporting person on June 2, 2025, which extends the period during which the vested option may be exercised following certain terminations of service. The amendment did not change the number of shares subject to the option, its exercise price, its vesting date or its expiration date, and the reporting person paid no consideration for it. The amendment is reported as the deemed cancellation of the original option and the grant of the amended option, each of which is exempt under Rule 16b-3.
- F2: The option became exercisable in full on June 2, 2026.
