MIGAUSKY GEORGE V 4

What Happened

• George V. Migausky, a director of REGENXBIO, was granted equity awards on May 29, 2026: 9,807 restricted stock units (RSUs) and a derivative award (stock option) for 46,600 shares. Both awards were granted at $0.00 (no cash exchanged). Total potential shares = 56,407. These are awards (not open‑market purchases or sales).

Key Details

• Transaction date: May 29, 2026; filing date: June 2, 2026 (filed within the required two business days).
• Price: $0.00 for both awards (code A — grant/award).
• Vesting: Per footnotes, 100% of the RSUs and the option vest on May 29, 2027, subject to the recipient’s continued service.
• Shares owned after transaction: Not specified in this Form 4 filing.
• Footnotes: F1 = RSU vests 100% on 5/29/2027; F2 = option vests on 5/29/2027 (continuous service condition).

Context

• RSUs convert to shares upon vesting; the option gives the right to purchase shares if and when vested and exercised. Neither award represents immediately tradable shares today and no cash was paid. Such time‑based grants are common for directors and reflect compensation, not an open‑market investment decision.
