Insights

Insider trading analyst

Routine RSU vesting and tax withholding by MeiraGTx’s CFO & COO, with no clear shift in investment thesis.

Richard Giroux, CFO & COO of MeiraGTx Holdings plc, reported vesting of 52,500 restricted share units on January 7, 2026, with each RSU converting into one ordinary share. This reflects previously granted compensation from January 7, 2022, rather than a new award.

To satisfy tax obligations on the vesting, 28,822 ordinary shares were withheld at $7.73 per share, a common mechanism for equity awards. After these transactions, Giroux’s direct beneficial ownership stood at 853,172 ordinary shares, indicating a substantial ongoing stake aligned with shareholders.

The filing does not indicate discretionary open-market buying or selling; it primarily documents scheduled vesting and related tax withholding. Future company filings may provide additional context on any new grants or changes in overall insider ownership levels.
