- Board approved Nov 4, 2026 the Option Amendment the Compensation Committee adopted in October 2026, applying it to President and COO Marc Horstman's stock option.

- Under the amendment, an other-than-cause termination keeps the option vesting on schedule and exercisable until expiration; resignation exercise window rises to 90 days from 30.
