## About

Ameren Master Retirement Trust was established in 1941 as the defined-benefit vehicle for Ameren Corporation employees. Ameren Corporation serves as plan sponsor and administrator while subsidiaries Union Electric Company, Ameren Illinois Company, and Ameren Transmission Company of Illinois participate in funding. The trust deploys assets across private real estate vehicles focused on mixed-use properties, commodity exposure accessed through target-date funds, and derivative instruments. Geographic reach centers on North American operations tied to Ameren’s regulated utilities in Missouri and Illinois. No fund-of-funds commitments or external co-investors appear in available records. Governance rests with the Finance Committee led by Ward H. Dickson and the Investment Committee under Martin J. Lyons, Jr. The plan maintains a separate philanthropic vehicle, the Ameren Corporation Charitable Trust. No operational events from the last 24 months are recorded in public sources. The trust’s architecture is defined by its direct tie to a single corporate sponsor and its regulatory posture as a qualified pension plan rather than a discretionary family or multi-client vehicle.
