WEISNER AIMEE S 4

What Happened
Aimee S. Weisner, a director of Glaukos Corp (GKOS), exercised 15,000 stock options on Feb 19, 2026 at a strike of $24.69 (cost ~ $370,350) and then sold a total of 15,000 common shares in multiple open-market trades for aggregate proceeds of about $1,760,762. The filing also shows a 980-share transfer to the Saeman Weisner Family Trust (a gift/transfer of ownership). The activity appears to be an exercise followed by immediate sales (cash-out of exercised shares).

Context

• This sequence (exercise of options at a low strike followed by immediate open-market sales) is a common way for insiders to realize gains from long-dated options; it does not by itself indicate a change in company outlook.
• The 980-share transfer to a family trust is a non-market transfer (a gift/ownership restructuring), which generally does not signal trading sentiment.
• The filing includes price ranges and weighted-average prices because the sales were executed in multiple trades; the reporting person offers to provide full trade-level details on request.
