KOSTER CHRISTOPHER 4

What Happened
Christopher Koster, Centene’s Secretary & General Counsel, was granted a total of 126,925 equity units on January 26, 2026 (transaction code A). The grant was reported at $0.00 per share because it is an award of restricted stock units (RSUs) and performance stock units (PSUs), not a market purchase or cash transaction.

Key Details

• Transaction date: 2026-01-26 (Form 4 filed 2026-01-28, timely within the standard two-business-day window)
• Award amount: 126,925 units at $0.00 per unit (grant/award)
• Breakdown (per filing footnotes): 50,770 RSUs vesting in three annual installments beginning March 15, 2027; 76,155 PSUs reported at target. PSU vesting may range from 0%–200% of target based on specified stock-price performance metrics.
• Ownership after grant: the filing notes at least 150,513 previously granted RSUs/PSUs plus the new 126,925-unit grant — i.e., at least 277,438 units now reflected in ownership, plus additional common shares acquired via the company’s ESPP (number not specified).
• Related holdings/terms: filing references an earlier performance stock option (Dec 15, 2021) with a $100-price vesting condition, and phantom stock awards that pay the fair market value and may be settled in cash or non‑company securities upon termination.
• Transaction code: A = Award/Grant.

Context
This was a compensation award, not an open-market buy or sell. RSUs typically vest over time and PSUs vest only if performance conditions are met — here, PSU payout depends on Centene’s stock-price performance over specified measurement periods and could result in no payout or up to 200% of target. Such awards reflect company compensation practices rather than immediate insider buying or selling intent.
