Burns Thomas William 4

What Happened
Thomas William Burns, Chairman and CEO of GLAUKOS Corp (GKOS), was the recipient of multiple performance-based awards reported on a Form 4 dated 2026-03-27 for transactions on 2026-03-25. The filing shows five award line items totaling 251,225 share-equivalents: 9,380 and 14,184 RSU shares reported at $0.00 (standard restricted stock units), plus three derivative awards covering 18,933, 110,254 and 98,474 share-equivalents (reported as derivative/option-related awards). These awards were granted/recognized because the company’s Compensation, Nominating and Governance Committee determined certain operational performance targets had been met. Portions of the awards vest in March 2026 and December 2026; a new option grant also carries a four‑year vesting schedule.

Context

• These are performance-based RSUs and option-related awards recognized after pre-determined operational targets were met — not cash purchases or sales. Awards (RSUs) are typically reported with $0 acquisition price because no cash changed hands at grant. Derivative entries reflect option/award accounting and vesting, not immediate cash proceeds.
• For retail investors: awards to executives signal compensation/retention and recognition of achieved targets, but do not directly indicate the insider is buying or selling shares for investment reasons.
