What Happened
- Mark Reinstra, Chief Legal Officer and Corporate Secretary of Roblox Corporation (RBLX), sold a total of 18,653 shares on April 13, 2026 in two open-market transactions for aggregate proceeds of about $1,080,808. The larger sale was 18,553 shares at an average price of $57.94 (total ≈ $1,074,961); a separate sale was 100 shares at $58.47 (≈ $5,847). These were sales (not purchases or option exercises).
Key Details
- Transaction date: April 13, 2026; filing date: April 15, 2026 (filed within the typical two-business-day Form 4 window).
- Prices: 18,553 shares at an average $57.94 (actual sale prices ranged $57.43–$58.42 per footnote); 100 shares at $58.47.
- Total proceeds: approximately $1,080,808.
- Shares owned after transaction: Not specified in the excerpt provided — see the full Form 4 for post-transaction holdings.
- Notable footnotes:
- F1: The 18,553-share sale was a required "sell-to-cover" to satisfy statutory tax withholding on the vesting of the final tranche of performance stock units (PSUs) granted April 13, 2023 — not a discretionary sale by the insider.
- F2: The reported $57.94 is an average price; the seller can provide a transaction-by-transaction price breakdown on request.
- F3: Some reported securities are Restricted Stock Units (RSUs) that convert to shares when vested.
- F4–F8: Certain shares are held in trusts (San Domenico Trust and multiple Reinstra annuity trusts); Reinstra serves as trustee and may be deemed the beneficial owner of those trust-held shares.
Context
- Sell-to-cover transactions are routine tax-withholding sales tied to vesting events and are not generally interpreted as a discretionary negative signal about the company's prospects. The smaller 100-share open-market sale appears separate from the tax-mandated sale. For full holdings, exact per-lot prices, or additional context, consult the complete Form 4 (Accession No. 0001315098-26-000089).
