Centene Corp’s Secretary & General Counsel, Christopher Koster, sold 56,500 shares of common stock for roughly $3.8 million at about $66.90 per share, retaining approximately 248,954 shares (including spouse-held shares) plus substantial unvested equity awards.

On August 26, 2026, Centene Corp’s Secretary & General Counsel, Christopher Koster, sold 56,500 shares of Centene common stock in an open market transaction at a weighted average price of approximately $66.90 per share, for proceeds of about $3.78 million, leaving him with 248,853.991 shares held directly plus 100 shares held indirectly through his spouse, and including 229,874 shares of previously granted restricted and performance stock units subject to vesting. The sales were executed in a narrow price range of $66.90 to $66.91, suggesting a single planned liquidity event rather than a series of opportunistic trades; based on the current stock price of about $65.33, his remaining direct and indirect equity stake is worth roughly $16.3 million, exclusive of the unvested RSUs and PSUs, which represent additional contingent value. Overall, this is a sizable insider sale by a senior legal executive but does not appear to be associated with any unusual equity grant or structural change in ownership beyond normal portfolio rebalancing.
