Insider Adoption or Termination of Trading Arrangements

During the fiscal quarter ended March 31, 2025, none of our directors or officers informed us of the adoption or termination of a “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement,” as those terms are defined in Regulation S-K, Item 408, except as follows:

On March 11, 2025, Martin J. Lyons, Jr., Chairman, President, and Chief Executive Officer of Ameren, adopted a Rule 10b5-1 trading arrangement. Mr. Lyons’ Rule 10b5-1 trading arrangement provides for the sale of 75% of any net shares of Ameren common stock received, after tax withholding, in connection with certain previously awarded restricted stock units and performance share units that will vest upon payment in March 2026 and March 2027. The estimated maximum number of shares to be sold pursuant to the Rule 10b5-1 trading arrangement is 62,686 shares. The actual number of shares sold pursuant to the Rule 10b5-1 trading arrangement will depend on the actual number of shares earned pursuant to the awards, which is generally dependent on the Company's achievement of certain performance measures, the actual dividends paid by the Company during the applicable vesting periods, and Mr. Lyons’ continued employment and individual performance during the applicable vesting periods. Mr. Lyons’ Rule 10b5-1 trading arrangement will terminate on the earlier of: (i) March 31, 2027; (ii) execution of all trades or expiration of all orders relating to such trades under the Rule 10b5-1 trading arrangement; or (iii) such date as the Rule 10b5-1 trading arrangement is otherwise terminated according to its terms.

On March 14, 2025, Michael L. Moehn, Senior Executive Vice President and Chief Financial Officer of Ameren, adopted a Rule 10b5-1 trading arrangement. Mr. Moehn's Rule 10b5-1 trading arrangement provides for the sale of an aggregate 26,000 shares to be sold in four equal quarterly installments between August 2025 and July 2026. Mr. Moehn’s Rule 10b5-1 trading arrangement will terminate on the earlier of: (i) July 31, 2026; (ii) execution
