Mark Creech

Mark Creech serves as Chairman, President, and CEO of Ameren Corporation, a regulated utility holding company providing electric and natural gas service to 2.4 million electric and 900,000 gas customers across Missouri and Illinois through its subsidiaries Ameren Missouri and Ameren Illinois. The company operates a diverse generation fleet and an extensive transmission and distribution network. Creech's strategic focus is on Ameren's ambitious capital investment program, which targets over $50 billion in infrastructure investment over the next decade. This spending supports grid modernization, renewable energy development, transmission expansion, and the retirement of coal-fired generation. Ameren benefits from constructive regulatory environments in both Missouri (with favorable legislation supporting utility investment) and Illinois (with formula rate-making for the transmission and distribution business). His key decisions involve capital deployment pace, regulatory strategy in two different state jurisdictions, generation fleet transition from coal to renewables, grid reliability investment, and managing customer rate impacts from the large capital program. Ameren's stock is valued as a premium regulated utility with above-average rate base growth.
