Armstrong Jason 4

What Happened

• Jason Armstrong, CFO of Comcast Corporation (CMCSA), had 8,150 restricted stock units (RSUs) vest and convert to 8,150 shares on Jan 20, 2026 (exercise/conversion reported as code M). The RSUs had no exercise price ($0).
• To cover tax withholding (code F), 3,950 of those shares were surrendered/sold at $28.42 per share, generating proceeds/withholding of $112,259. The net result of this vesting event was retention of 4,200 shares (8,150 vested − 3,950 withheld).

• Prices and amounts: 8,150 RSUs converted to shares @ $0.00; 3,950 shares withheld/sold @ $28.42 for $112,259.
• Net shares retained from this vesting: 4,200 shares.

Context

• This was a vesting of RSUs with routine tax-withholding share surrender/sale — a common administrative sale tied to compensation, not an open-market investment decision. RSU conversions are non-cash awards; selling a portion to cover taxes does not necessarily signal confidence or concern about the stock.
• The filing appears timely. If you track insider buying for signals, note that this event is primarily compensation-related rather than a discretionary purchase.
