About
Ameren Corporation is a St. Louis, Missouri-based regulated electric and natural gas utility holding company — publicly traded on the New York Stock Exchange (NYSE: AEE) as an S&P 500 Utilities component — serving approximately 2.4 million electric customers and 900,000 natural gas customers in Missouri and Illinois through two primary regulated subsidiaries: AmerenMissouri (electric and gas in Missouri, including the Callaway Nuclear Power Station — Missouri's only commercial nuclear plant) and AmerenIllinois (electric and gas distribution across central and southern Illinois), through approximately 9,000 employees. In fiscal year 2024, Ameren reported revenue of approximately $8.2 billion, with continued capital investment in transmission upgrades, distribution modernization, and renewable energy additions. Ameren Missouri's clean energy transition includes the announced Reform Renewable Energy Center — a 250-megawatt solar facility near the Callaway Nuclear site, with construction beginning in 2026 and expected to power 44,000 homes by 2028, creating 300 construction jobs. CEO Martin Lyons, who succeeded Warner Baxter in 2022, has maintained Ameren's steady capital investment trajectory targeting 6-8% annual EPS growth through infrastructure modernization and renewable energy additions in both states. The company's transmission infrastructure — spanning MISO (Midcontinent Independent System Operator) in Missouri and PJM Interconnection in Illinois — positions Ameren to benefit from grid investment programs enabling renewable energy integration across the Midwest.

About
CMS Energy Corporation is a Jackson, Michigan-based regulated electric and gas utility holding company — publicly traded on the New York Stock Exchange (NYSE: CMS) as an S&P 500 Utilities component — serving approximately 6.8 million electric and 1.8 million natural gas customers throughout Michigan through its principal subsidiary Consumers Energy (Michigan's largest utility, serving 68 of Michigan's 83 counties) through approximately 7,500 employees. In fiscal year 2024, CMS Energy reported revenues of approximately $8.4 billion and adjusted EPS of approximately $3.29, growing within the company's 6-8% annual adjusted EPS guidance range that has made CMS Energy one of the most consistent earnings growth utilities in the US — delivering 18 consecutive years of meeting or exceeding earnings guidance under the management team's "CE Way" lean operational improvement program. CEO Garrick Rochow leads CMS Energy's strategy of executing a $20+ billion capital plan (2024-2028) focused on renewable energy generation (wind and solar replacing coal-fired generation ahead of the Michigan Public Service Commission's clean energy mandate), electric distribution grid hardening (replacing 1,750 miles of distribution lines annually to reduce storm outage frequency and duration), and natural gas infrastructure modernization. Michigan's Governor Whitmer's 100% clean energy by 2040 mandate (PA 235 — enacted 2023) requires Consumers Energy to retire coal plants, add significant renewable energy generation, and build battery storage — translating directly into approved rate base capital investment that earns Consumers Energy's authorized return on equity (approximately 9.9%).
