Seidler Eric V 4

What Happened

• Eric V. Seidler, Senior Vice President of a subsidiary of Ameren Corporation, acquired a total of 3,430 shares on Feb 5, 2026 through two award-type transactions: 1,066 share equivalents in the company savings/unitized fund and 2,364 restricted/awarded shares. Both transactions are recorded at $0.00 per share (these are awards/grant entries, not open-market purchases), so no cash was paid on the report date. Some of the shares reflect newly granted restricted stock units (RSUs) and some reflect shares acquired upon vesting of previously awarded performance share units and dividend reinvestment.

Key Details

• Transaction date: February 5, 2026; Form 4 filed Feb 9, 2026 (timely within the 2-business-day filing window).
• Transactions reported as type "A" (award/acquisition): 1,066 shares @ $0.00 and 2,364 shares @ $0.00 — total 3,430 shares.
• Shares owned after transaction: not specified in the filing excerpt provided.
• Notable footnotes from the filing:
  • F1: 1,066 figure represents estimated share equivalents in the Ameren Savings Investment Plan as of Jan 31, 2026.
  • F2: The RSUs were granted under Ameren’s 2022 Omnibus Incentive Compensation Plan and are scheduled to vest on the payment date in 2029 (no later than March 15, 2029), subject to plan terms.
  • F3: Some shares were acquired upon vesting of previously granted performance share units.
  • F4: Includes dividend reinvestment — 17 shares from reinvested dividends plus 41 accrued dividend equivalents from RSUs in Q4 2025.
• No indication of tax-withholding sales or a 10b5-1 plan in the reported notes.

Context

• These transactions are compensation-related (awards, unitized plan holdings, and vesting of performance units), not open-market buys or sales. Such grants and vesting events are common forms of executive compensation and do not, by themselves, signal a buy or sell decision by the insider.
• The RSUs carry future vesting/payment conditions (not immediate free tradable shares) per the plan and award agreements; performance-unit vesting results in shares already delivered per the filing.
