ST. LOUIS, May 23, 2025 — Ameren Corporation has announced today that it will donate $1 million to aid in the recovery from the severe storms and tornado that impacted the St. Louis area and nearby regions on Friday, May 16.

“These devastating storms deeply affected our communities, impacting our customers, employees, neighbors, and friends,” said Martin J. Lyons Jr., chairman, president, and CEO of Ameren. “The extent of the damage is truly disheartening, but our teams are working diligently to restore what was lost. This $1 million donation is another demonstration of our commitment to stand with the communities we serve as they embark on the difficult recovery process.”

Ameren will allocate $750,000 to local organizations to support ongoing recovery initiatives. The recipient organizations include the United Way of Greater St. Louis, the American Red Cross, The Salvation Army, the Urban League of Metropolitan St. Louis, and the City of St. Louis Tornado Response Fund.
