Significance 4

MGTX CEO Forbes Alexandria sold 62,000 shares ($568.5K) via scheduled 10b5-1 plan; stock -9.8% in 30 days

Forbes Alexandria, as President & CEO, executed a sale of 62,000 shares at $9.17 on 2026-05-19 under a pre-arranged 10b5-1 trading plan adopted on 2025-11-18, reducing his holdings from 1,449,695 to 1,387,695 shares. This is a scheduled transaction, not a discretionary decision. The current stock price is $9.13, down 9.8% over the preceding 30 days and 23.0% from the 52-week high of $11.85, indicating recent price deterioration. MeiraGTx remains unprofitable (full-year net income: $-46.3M) despite strong revenue growth of +144.6%, creating fundamental uncertainty around the path to profitability that may warrant attention given the CEO's engagement in planned equity disposition.
