Kliman Gilbert H 4

What Happened Gilbert H. Kliman, a director of Glaukos Corp (GKOS), exercised 5,000 stock options on May 14, 2026 at an exercise price of $24.69 per share (cost $123,450) and the resulting 5,000 shares were sold the same day in an open-market transaction at $140.76 per share for proceeds of $703,800. The exercise plus immediate sale functions as a cashless exercise: he acquired shares by converting options and then disposed of those shares.

Context Because the exercised shares were sold immediately, this is effectively a cashless exercise to convert option value to cash rather than a long-term buy signal. Such transactions are common for insiders to cover exercise costs or diversify; they are factual disclosures of conversion plus sale and do not by themselves indicate the director’s view of the company’s prospects.
