Roblox (RBLX) Director Gina Mastantuono Defers 1,296 RSUs

What Happened
Gina Mastantuono, a director of Roblox Corporation (RBLX), reported that 1,296 vested Restricted Stock Units (RSUs) were converted into phantom stock on August 20, 2026. The Form 4 shows a simultaneous disposition of 1,296 shares of Class A common stock and an acquisition of 1,296 shares of phantom stock at $0.00 — i.e., no cash changed hands and the transaction has no immediate market value on the filing.

Key Details

• Transaction date: August 20, 2026; Form 4 filed August 24, 2026 (covers the Aug 20 vesting/deferral).
• Reported actions: Code J ("other acquisition or disposition") — 1,296 shares disposed of (Class A common) and 1,296 phantom shares acquired. Price reported: $0.00; total value reported: $0.
• Footnotes: RSUs vested and, per the issuer’s deferred compensation plan, the reporting person elected (or receipt was deferred) to receive phantom stock instead of actual shares (F1–F4). Each phantom share equals the right to one Class A share and is payable in a lump sum upon separation from service.
• Shares owned after transaction: not specified in the provided filing details.
• No cash sale or open-market transaction was reported; this is a deferral/derivative transaction, not a routine sale or purchase.

Context
Phantom stock is a deferred-compensation instrument that mirrors the economic value of shares but does not deliver actual stock until specified conditions (here, lump-sum payment upon separation). Such deferrals are administrative/compensation elections and do not necessarily indicate a buy or sell signal about the insider’s view of the company. The filing documents the conversion of vested RSUs into deferred phantom stock rather than a market transaction.
