Ameren delivers big economic benefits for Missouri and Illinois

Study estimates company's operations are generating more than $20.7 billion in annual economic output

ST. LOUIS, Jan. 15, 2026 /PRNewswire/ -- Ameren Corporation's (NYSE: AEE) operations in Missouri and Illinois triggered more than $20.7 billion in annual economic output, according to a study by a leading market research and development firm.

Conducted by HR&A Advisors and commissioned by Ameren, the study analyzed direct spending by the company on functions such as payroll, capital equipment, supplier services, and the additional economic benefits that are generated when those investments prompt other businesses and consumers to spend money on housing, capital goods and retail. In short, every dollar and job related to Ameren's operations in the bi-state area are generating additional leading-wage jobs, disposable income and increased tax revenue for communities and public institutions in the bi-state region.

Study Highlights

• Jobs: 55,200 supported by Ameren's annual economic activity
• Vendor/Suppliers: $2.2 billion purchased from in-state suppliers in Missouri and Illinois
• Taxes: $920 million contributed to state and local governments
• Philanthropy: $10.6 million in support to meet critical community needs

"Every day, our employees, suppliers and contractors are working to strengthen and expand our energy grid, bolstering reliability and resiliency for customers, while facilitating economic expansion," said Martin J. Lyons Jr., chairman, president and chief executive officer of Ameren Corporation. "The results of this economic impact study validate that our ongoing energy infrastructure investments and operations are delivering unprecedented benefits in the communities where we live and work."

The study also cites Ameren's annual efforts to manage costs and streamline operational efficiency to help mitigate the impact of rising energy costs. Efforts to keep rates as low as possible are increasing spending power for Ameren's residential and business customers, further contributing to economic impacts.

In addition, the technical assistance provided by Ameren to new, expanding and relocating businesses created 3,728 new jobs in the company's two-state service territory in 2025. In total, 73 economic development projects triggered $3.56 billion in capital investment by those businesses.
