Insights

Financial Analyst

TL;DR: Routine insider disposition recorded; beneficial ownership remains sizable at 56,816 shares, including dividend reinvestment.

The Form 4 documents a single disposal of 796 shares on 08/19/2025 coded as "G" with a recorded price of $0 and shows total beneficial ownership of 56,816 shares after the transaction. The filing also discloses 3,101 share equivalents held indirectly via the Ameren Savings Investment Plan and 126 accrued dividend equivalents from restricted stock units. For investors this appears to be a routine, clearly disclosed insider reporting event rather than an operational or financial development affecting company fundamentals.
