He received 6,797 shares of common stock at a reported price of $0.00 per share, described in a footnote as performance-based restricted stock units granted under Ameren’s 2022 Omnibus Incentive Compensation Plan.

"Award of performance-based restricted stock units pursuant to the issuer's 2022 Omnibus Incentive Compensation Plan"
Performance-based restricted stock units are a type of employee equity award that converts into company shares only if predefined financial or operational targets are met over a set period. Think of it like a bonus check that becomes stock only when specific goals are hit; it ties pay to results, aligning managers’ incentives with shareholders. Investors care because these awards affect future share count, executive incentives, and signal how management’s success will be measured and rewarded.
