Mastantuono Gina 4

What Happened

• Gina Mastantuono, a director of Roblox Corp (RBLX), received a grant of 5,185 restricted stock units (RSUs) on May 28, 2026 (report shows $0 per share for award value). On May 27, 2026 she reported the disposition of 1,126 vested Class A shares in exchange for an equal number of phantom stock units under the company’s deferred compensation plan (also reported at $0). These were compensation-related actions (awards and deferral), not open-market purchases or sales.

Key Details

• Transaction dates and types:
  • 2026-05-27: Disposition of 1,126 Class A shares in exchange for phantom stock (code J) — reported $0 proceeds (internal deferral, not a market sale).
  • 2026-05-27: Acquisition of 1,126 derivative phantom stock units (code J) — $0.
  • 2026-05-28: Grant of 5,185 RSUs (code A) — $0.
• Shares owned after the transactions: not disclosed in the provided filing excerpt.
• Notable footnotes:
  • The 1,126 shares were deferred at vesting into phantom stock under the issuer’s deferred comp plan (phantom = right to one share; payable in lump sum on separation).
  • The 5,185 securities are RSUs; vesting schedule (per filing) vests in four installments (Aug 20, 2026; Nov 20, 2026; Feb 20, 2027; and earlier of day before 2027 annual meeting or May 28, 2027), subject to continued service.
• Timeliness: Form filed May 29, 2026 for transactions through May 27, 2026 — filing appears timely (filed within the typical 2-business-day Form 4 window).

Context

• RSUs and phantom stock are compensation instruments. The disposition reported here reflects an internal deferral (vesting shares converted into phantom units), not a market sale that would signal immediate cashing out. The new RSUs will vest over time per the schedule above and represent contingent rights to receive shares in the future.
