GLAUKOS (GKOS) President Joseph Gilliam Receives Stock Awards
What Happened Joseph E. Gilliam, President and Chief Operating Officer of GLAUKOS Corp (GKOS), was reported to have acquired a total of 98,789 shares on March 25, 2026.

Key Details
- Transaction date: March 25, 2026; Form 4 filed March 27, 2026 (appears timely).
- Reported entries: 5,829; 17,792; 16,462 (derivative); 21,955 (derivative); 36,751 (derivative) — total 98,789 shares — all recorded at $0.00 per share.
- Shares owned after transaction: not specified in the supplied excerpt of the filing.
- Nature of awards: Includes restricted stock units (RSUs) and derivative awards/options portions tied to multi-year performance goals and/or time-based vesting; some portions remain unvested per the footnotes.
- Notable footnote points (from filing):
- Portions of awards come from prior grants (e.g., March 14, 2024 and March 22, 2023) whose vesting was contingent on multi-year operational targets; the Compensation/Nominating & Governance Committee determined certain targets were achieved as of March 25, 2026, triggering earned portions that will vest/deliver in March 2026.
- Some RSU grants vest pro rata over four years (25% each year); other awards are performance-vesting portions of stock options granted March 24, 2022, with staggered vesting (part in March 2026, part in December 2026).
- Footnotes indicate specific counts of RSUs that remain unvested (e.g., 31,962 and 49,754 in two noted footnotes).
Context
- These transactions are awards/vesting events (transaction code A) rather than cash purchases or open-market sales. Acquisitions at $0 typically reflect issuance upon vesting of RSUs or conversion of earned option portions, not an outlay by the insider.
- For retail investors, award/vesting filings signal that performance or timing conditions were met per company committees; they are informative about compensation realization but do not necessarily indicate the insider’s view on near-term stock direction.
