Conway Kevin John 4

What Happened

• Kevin J. Conway, Chief Financial Officer of Generation Bio (GBIO), had 235 restricted stock units convert into 235 shares on Feb 2, 2026 (reported on a Form 4 filed Feb 4, 2026). No cash exercise price was paid (reported $0.00).
• To cover tax withholding, 72 of the newly issued shares were withheld and disposed of at a reported per-share withholding value of $5.64, producing proceeds of $406.

Key Details

• Transaction dates: conversion/vesting and withholding occurred on 2026-02-02; Form 4 filed 2026-02-04. This appears timely (Form 4s are due within two business days).
• Prices/values: conversion reported at $0.00 (derivative conversion); tax withholding: 72 shares @ $5.64 = $406.
• Shares owned after transaction: not specified in the provided excerpt of the filing.
• Footnotes: F1 clarifies each restricted stock unit (RSU) represents one share. F2 notes a grant of 9,390 RSUs on Jan 20, 2023 vested in full on Feb 2, 2026 under the Merger Agreement; Conway’s filing shows 235 RSUs converted.
• Transaction codes: M = exercise/conversion of derivative (here, RSU conversion); F = shares withheld to satisfy tax withholding.

Context

• This was a conversion/vesting event (not a cash purchase or open-market sale). The withholding of shares to cover taxes is a routine administrative step and does not by itself indicate buying or selling sentiment. The accelerated vesting is tied to the Merger Agreement referenced in the footnote.
