OTHER INFORMATION.\n\nInsider Adoption or Termination of Trading Arrangements\n\nDuring the fiscal quarter ended March 31, 2026, 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:\n\nOn February 24, 2026, Michael L. Moehn, Group President of Ameren Utilities and Interim Chairman and President of Ameren Missouri, adopted a Rule 10b5‑1 trading arrangement that provides for the sale of an aggregate of up to 26,000 shares of Ameren common stock, to be sold in four equal quarterly installments, beginning in August 2026 and continuing through May 2027, subject to certain price limitations set forth in the trading arrangement. Mr. Moehn’s Rule 10b5‑1 trading arrangement will terminate on the earlier of: (i) July 30, 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.\n\nOn February 24, 2026, Mark C. Lindgren, Executive Vice President, Communications, and Chief Human Resources Officer of Ameren Services Company, adopted a Rule 10b5‑1 trading arrangement that provides for the sale of 50% of any net shares of Ameren common stock received, after tax withholding, in connection with certain previously awarded performance share units and restricted stock units that will vest upon payment in March 2027 and March 2028. The estimated maximum number of shares to be sold pursuant to the Rule 10b5-1 trading arrangement is 5,272 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. Lindgren's continued employment during the applicable vesting periods. Mr. Lindgren’s Rule 10b5‑1 trading arrangement will terminate on the earlier of: (i) March 17, 2028; (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.\n\nEach of the trading arrangements discussed above are intended to satisfy the affirmative defense conditions of Rule 10b5-1(c).\n\n65\n\n[Table of Contents](#i2bbbbcf22f934398bf3fcad73ef0f1bd_7)"}
