RBLX Form 4: Jason Kilar shifts RSUs into phantom stock units

Rhea-AI Filing Summary

Roblox Corp (RBLX) director Jason Kilar reported a change in his equity holdings tied to the vesting of previously granted restricted stock units (RSUs) on November 20, 2025. Instead of taking delivery of 1,125 shares of Class A common stock upon vesting, he deferred this amount into the company’s deferred compensation plan, receiving 1,125 shares of phantom stock with a stated price of $0 per unit. This is reported as a disposition of 1,125 Class A shares and a corresponding acquisition of 1,125 phantom stock units.

Following this transaction, Kilar beneficially owns 17,289 shares of Roblox Class A common stock and 2,250 phantom stock units, all held directly. Each RSU and each phantom stock unit represents a right to receive one share of Roblox Class A common stock, with the phantom stock payable in a lump sum upon separation from service. The filing also notes that the transaction was made under a Rule 10b5‑1 plan.

Explanation of Responses:

1. In connection with the vesting on November 20, 2025, of Restricted Stock Units ("RSUs") previously granted to the Reporting Person, the Reporting Person's receipt of 1,125 shares of Class A Common Stock was deferred, resulting in the Reporting Person's receipt instead of 1,125 shares of phantom stock pursuant to the Issuer's deferred compensation plan. The Reporting Person is therefore reporting the disposition of 1,125 shares of Class A Common Stock in exchange for an equal number of shares of phantom stock.

2. 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.

3. Each share of phantom stock represents a right to receive one share of Class A common stock.

4. The phantom stock becomes payable in one lump sum payment upon separation from service.
