KOSTER CHRISTOPHER 4/A

What Happened

• Christopher Koster, Secretary & General Counsel of Centene Corp (CNC), received an equity award on January 26, 2026 totaling 126,925 share-equivalent units reported at $0.00. The award consists of 50,770 restricted stock units (RSUs) and 76,155 performance stock units (PSUs) reported at target.
• The RSUs vest in three annual installments beginning March 15, 2027. The PSUs are performance-based and will vest (if any) on March 15, 2029 at between 0% and 200% of target depending on Centene’s stock-price performance (final 20 trading days of 2025 compared with the final 60 trading days of 2028).
• This filing is an amendment (Form 4/A) to correct previously reported holdings; the amendment removes 26,939 unvested PSUs for the 2025 performance period that did not meet vesting criteria.

Key Details

• Transaction date: 2026-01-26 — Grant/Award (code A). Reported price: $0.00 per share-equivalent; total reported value $0.
• Shares granted: 126,925 (50,770 RSUs; 76,155 PSUs at target). PSU payout range: 0%–200% of target, vesting date March 15, 2029 (subject to performance).
• Amendment: Form 4/A filed 2026-02-06 to amend the Form 4 filed 2026-01-28; amendment removes 26,939 unvested PSUs that did not vest per Compensation & Talent Committee determination on Jan 26, 2026.
• Post-transaction holdings: filing does not state a single total beneficial ownership figure after this award; it notes ownership includes 123,574 previously-granted RSUs and PSUs (reported at target) that remain subject to vesting.
• No sale, purchase, or option exercise occurred; this is a compensation grant (not a market purchase or sale).

Context

• RSUs and PSUs are common forms of executive compensation. PSUs are performance-conditioned — the final payout can vary based on predefined stock-performance metrics — so the ultimate number of shares that vest could be higher or lower than the target shown here.
• This amendment corrects previously reported holdings rather than reporting a new trading activity; it does not by itself indicate a buy or sell signal.
