Giroux Richard 4

What Happened

• Richard Giroux, CFO and COO of MeiraGTx Holdings plc (MGTX), had one-half of a restricted share unit (RSU) grant vest on Jan 17, 2026 (310,000 RSUs). Each RSU converted into one ordinary share on vesting. To satisfy tax withholding, 163,916 shares were withheld at $7.42 per share, yielding $1,216,257 in tax withholding. The vesting resulted in a net issuance to Giroux of 146,084 ordinary shares (310,000 vested − 163,916 withheld).
• Transaction codes on the Form 4: M = conversion/exercise of derivative (RSU conversion), F = shares withheld for payment of taxes. The filing shows the conversion/vesting and the corresponding withholding; this is a compensation/vesting event rather than an open-market purchase or discretionary sale.

• This is a routine equity compensation vesting and tax-withholding event (cashless share withholding), not an open-market sale or purchase.

Context

• For retail investors: RSU vesting and share withholding for taxes are common executive compensation events and do not necessarily signal a change in insider sentiment. The withheld shares are treated as a disposition for tax purposes but originate from a compensation award.
