Centene (CNC) General Counsel Christopher Koster Sells Shares
What Happened
Christopher Koster, Centene's Secretary & General Counsel, had 9,087 shares disposed on March 15, 2026 to cover tax withholding tied to vested restricted stock units (RSUs).

Key Details
- Transaction date: 2026-03-15; filing date: 2026-03-17 (Form 4 filed timely).
- Disposition: 9,087 shares withheld for taxes at $34.45 per share; total value ~$313,047.

Context
Tax-withholding disposals on RSU vesting are common and typically routine administrative events rather than insider-driven sales indicating a view on the company's stock. This was a cashless-type settlement by withholding shares to cover taxes; no open-market sale details are provided. The filing also notes other equity interests (PSUs, RSUs, a performance option, and phantom stock), which affect Mr. Koster’s overall economic exposure but do not change the routine nature of this tax-related disposition.
