Insider Adoption or Termination of Trading Arrangements

During the fiscal quarter ended September 30, 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:

Shaw, Senior Vice President, Finance and Chief Accounting Officer of Ameren, adopted a Rule 10b5-1 trading arrangement that provides for the sale of an aggregate of up to 1,300 shares to be sold in four equal quarterly installments between November 2025 and November 2026, subject to certain price limitations set forth in the trading arrangement. Ms. Shaw’s 10b5-1 trading arrangement will terminate on the earlier of: (i) November 13, 2026; (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.

The trading arrangement discussed above is intended to satisfy the affirmative defense conditions of Rule 10b5-1(c).
