McDonough Claire 4

What Happened Claire McDonough, Chief Financial Officer of Rivian Automotive (RIVN), received equity awards on March 20, 2026: 264,201 restricted stock units (RSUs) and an award covering 528,402 derivative option shares. Both entries show an acquisition price of $0 (typical for compensation grants), so no cash changed hands. These are compensation awards, not open-market purchases or sales.

Key Details

• Transaction date: March 20, 2026; Form 4 filed March 24, 2026 (within the standard two-business-day reporting window).
• RSUs: 264,201 RSUs granted at $0. Each RSU represents a contingent right to one share and has no expiration.
• Option/derivative: 528,402 shares shown as a derivative award (stock option) at $0.
• Vesting (from footnotes):
  • RSUs vest quarterly over the next 16 quarterly anniversaries beginning Feb 15, 2026 (i.e., roughly four years of quarterly vesting).
  • The stock option vests 25% annually over the next four anniversaries starting March 20, 2026.
• Shares owned after the transaction: not specified in the provided excerpt of the filing.
• Filing timeliness: filed March 24 for a March 20 transaction — appears timely.

Context These grants are compensation awards that vest over time; they do not represent an immediate purchase or sale of shares. RSUs convert to shares upon vesting; the option award vests over four years and would only result in shares if and when vested (and exercised if applicable). Such awards are common for executive compensation and do not by themselves indicate insider buying or selling activity.
