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
Expand Energy Corporation is an Oklahoma City, Oklahoma-based natural gas exploration and production company — publicly traded on the NASDAQ (NASDAQ: EXE) — formed through the October 2024 merger of Chesapeake Energy Corporation and Southwestern Energy Company, creating the largest pure-play natural gas producer in the United States by volume with production exceeding 7.3 billion cubic feet per day equivalent (Bcfe/d) across the Appalachian Basin (Marcellus and Utica shale in Pennsylvania, West Virginia, and Ohio) and Mid-Continent (Haynesville shale in Louisiana and Texas). Chesapeake Energy rebranded as Expand Energy upon closing the $7.4 billion all-stock acquisition of Southwestern Energy, combining Chesapeake's Haynesville and Marcellus positions with Southwestern's dominant Appalachia and Haynesville footprint to create a company with 6,300 net wells, 1.6 million net acres across core natural gas basins, and estimated proved reserves exceeding 20 trillion cubic feet equivalent (Tcfe). CEO Domenic Dell'Osso leads Expand Energy's strategy of consolidating the US natural gas producer landscape to capture economies of scale in drilling operations, midstream contracting, and LNG export supply agreements — positioning the combined company as a reliable long-term supplier to US liquefied natural gas (LNG) export terminals that require 20-year take-or-pay supply commitments from creditworthy, large-scale gas producers. The Expand Energy name reflects the company's positioning around expanding US natural gas supply for LNG exports that serve Europe's energy security needs following Russia's reduction of pipeline gas supplies to the continent.
