ST. LOUIS, Mo (Oct. 20, 2025) — Ameren Corporation has announced a strategic realignment of its executive leadership team, including the creation of a new group president role designed to enhance utility operations and support long-term growth.

Michael Moehn, currently senior executive vice president and chief financial officer of Ameren Corporation, chairman and president of Ameren Services, and interim chairman and president of Ameren Missouri, will assume the newly created position of group president, Ameren Utilities. In this role, Moehn will oversee all of Ameren’s operating utilities, with the presidents of Ameren Missouri, Ameren Illinois, and Ameren Transmission Company of Illinois reporting directly to him.

Lenny Singh, currently chairman and president of Ameren Illinois, will succeed Moehn as executive vice president and chief financial officer of Ameren Corporation and chairman and president of Ameren Services. Singh will continue reporting to Martin J. Lyons Jr., chairman, president and chief executive officer of Ameren Corporation.

Patrick Smith Sr., currently senior vice president of operations and technical services, will become chairman and president of Ameren Illinois, reporting to Moehn. Smith began his career at Ameren as a meter reader in 1985 and has held numerous leadership roles in field operations, engineering, safety, and emergency response.

Lyons said the leadership transitions are part of a broader strategy to enhance efficiency and value across the company’s operations.

“This strategic rotation of responsibilities reflects Ameren’s strong commitment to continuous improvement at all levels of our organization,” Lyons said. “It is part of a deliberate process designed to consistently deliver exceptional value to our customers, the communities we serve and our shareholders, as the energy industry continues to evolve.”

Shawn Schukar will continue in his role as chairman and president of Ameren Transmission Company of Illinois, which Lyons credited with driving “significant value” for customers and the company.

Moehn joined Ameren in 2000 and has served in multiple senior leadership roles, including as chairman and president of Ameren Missouri, with responsibilities spanning finance, strategy, regulatory affairs, nuclear operations and customer service.

Singh joined Ameren in 2022 after more than three decades at Consolidated Edison Company of New York, where he led operations across electric, gas, steam and shared services.

Lyons emphasized that the changes will help position Ameren for continued operational excellence and growth.

“We’re positioning Ameren for even greater effectiveness and efficiency,” Lyons said. “This enhanced structure enables us to streamline decision-making, optimize resource allocation, and deliver more consistent, high-quality service to our customers.”
