Navratil Tomas, Chief Development Officer at Glaukos Corporation (GKOS), has demonstrated a consistent pattern of selling activity over 28 reported transactions, with no recorded purchases. Since 2024, Navratil has exclusively divested GKOS shares, totaling approximately $1.71 million in aggregate sales. The transactions include a mix of open-market sales (coded "S") and dispositions under Rule 16b-3 (coded "F"), with the most significant sales occurring in September 2025, when Navratil sold $172,612 and $281,008 worth of shares on September 11. More recently, in March 2026, Navratil executed multiple dispositions, including a $267,916 transaction on March 24 and a $280,776 sale on March 23, alongside smaller sales totaling $101,078 on March 16.
The filings also show several awards (coded "A")—likely stock grants or option exercises—with no associated dollar value reported, suggesting these were non-cash transactions. The absence of any buy activity, combined with the repeated sales, indicates a clear divestment trend. Notably, the largest dispositions have occurred in concentrated bursts, such as the September 2025 and March 2026 sales, rather than steady, incremental selling. All transactions involve GKOS, reflecting Navratil’s exclusive trading activity in his employer’s stock. The pattern aligns with typical executive stock liquidation, though the frequency and size of recent sales may warrant closer attention for shifts in holding behavior.
