The 2022 Plan was previously approved by Ameren's Board of Directors ("Board") on February 11, 2022, subject to shareholder approval. The 2022 Plan has been established to replace, on a prospective basis, the Ameren Corporation 2014 Omnibus Incentive Compensation Plan (the “2014 Plan”), which was previously approved by shareholders and expires on April 24, 2024.   The 2022 Plan permits the grant of restricted stock, restricted stock units, stock options (incentive stock options and nonqualified stock options), stock appreciation rights, performance awards, cash-based awards and other stock-based awards. The 2022 Plan will be administered by the Human Resources Committee of the Board, or a subcommittee thereof, or any other committee designated by the Board to administer the 2022 Plan.   A total of 8,842,321 shares of common stock is available for grants under the 2022 Plan, representing 1,342,321 shares transferred from the 2014 Plan, plus 7,500,000 new shares. The number of shares available for grant is subject to adjustment under certain circumstances described in the 2022 Plan.   The Board may terminate or amend the 2022 Plan at any time; provided, however, that amendment of the 2022 Plan will be subject to stockholder approval in certain circumstances. The 2022 Plan will expire and no grants will be made thereunder on or after May 12, 2032.   This description of the 2022 Plan is a summary only and is qualified by reference to the 2022 Plan, which is filed as Exhibit 10.1 hereto. A more complete description of the terms of the 2022 Plan can be found in “Item 3 - Approval of the Ameren Corporation 2022 Omnibus Incentive Compensation Plan” on pages 82 to 86 of the Company’s definitive proxy statement filed with the Securities and Exchange Commission on March 29, 2022, which description is incorporated by reference herein.   ITEM 5.07 Submission of Matters to a Vote of Security Holders.   At the annual meeting of shareholders of each of Ameren, Union Electric Company, doing business as Ameren Missouri (“Ameren Missouri”), and Ameren Illinois Company, doing business as Ameren Illinois (“Ameren Illinois”), held on May 12, 2022, the matters listed below were submitted to a vote of each company’s respective shareholders.   Ameren   Item (1): Election of Directors The following individuals (comprising Ameren’s full Board of Directors) were elected:   Name   Votes For     Votes Against     Abstentions     Broker Non-Votes   Warner L.
