MeiraGTx (MGTX) CDO reports RSU vesting and tax share withholding

Rhea-AI Filing Summary

MeiraGTx Holdings plc Chief Development Officer Stuart Naylor reported equity award activity related to previously granted restricted share units. On February 21, 2026, one-quarter of his restricted share units granted on February 21, 2023 vested, resulting in 25,000 restricted share units converting into 25,000 ordinary shares, with no exercise price. Following this vesting and conversion, his direct holdings briefly totaled 707,916 ordinary shares. To cover tax obligations on the vesting, 11,750 ordinary shares were withheld and disposed of at $7.45 per share, a tax-withholding disposition rather than an open-market sale, leaving him with 696,166 ordinary shares held directly.
