Roblox (RBLX) Director Gina Mastantuono Receives RSU Award

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.

Footnotes (5)

[F1]In connection with the vesting on May 27, 2026, of Restricted Stock Units ("RSUs") previously granted to the Reporting Person, the Reporting Person's receipt of 1,126 shares of Class A Common Stock was deferred, resulting in the Reporting Person's receipt instead of 1,126 shares of phantom stock pursuant to the Issuer's deferred compensation plan. The Reporting Person is therefore reporting the disposition of 1,126 shares of Class A Common Stock in exchange for an equal number of shares of phantom stock.
[F2]A portion of these securities are Restricted Stock Units ("RSUs"). Each RSU represents a contingent right to receive one share of the Issuer's Class A Common Stock.
[F3]These securities are Restricted Stock Units ("RSUs"). Each RSU represents a contingent right to receive one share of the Issuer's Class A Common Stock. 1/4th of the RSUs shall vest on each of August 20, 2026, November 20, 2026 and February 20, 2027, and the remaining 1/4th of the RSUs shall vest on the earlier of (i) the day before the annual meeting of stockholders held in 2027 or (ii) May 28, 2027, subject to the Reporting Person continuing as a service provider through each vest date.
[F4]Each share of phantom stock represents a right to receive one share of Class A common stock.
[F5]The phantom stock becomes payable in one lump sum payment upon separation from service.
