McBride Suzanne E. 4

What Happened Suzanne E. McBride, Chief Operations Officer and a director at Iridium Communications (IRDM), received a mix of restricted stock units (RSUs) and performance stock units (PSUs) in late Feb/early Mar 2026 and had 20,479 shares withheld by the issuer to satisfy tax withholding. Awards recorded: 7,329 shares (02/26), 34,247 shares (02/26), and 133,611 shares (03/01) — all shown at $0 since these are equity awards rather than purchases. The issuer withheld 20,479 shares on 03/01 at a reported value of $22.49/share, totaling $460,573, to cover tax obligations.

  • F2: PSUs granted Mar 1, 2024 — half settled Mar 1, 2026, remaining settle Mar 1, 2027.
  • F3: Long-term RSU award vests 20% on Mar 1, 2027 with remaining shares vesting quarterly through Mar 1, 2031.

Context These transactions are award grants (A) and a tax-withholding disposition (F). RSUs and PSUs are contingent equity awards that convert to shares on vesting or settlement; they are not open-market purchases and do not directly signal a buy decision. The withholding of shares to cover taxes is routine after awards vest/settle and is distinct from a sale by the insider on the open market.
