About

Form Energy develops iron-air batteries — a long-duration energy storage technology that stores electricity for 100+ hours using iron plates that rust (oxidize) to discharge and reverse the process to charge. In February 2026, Google signed a $1 billion contract for iron-air batteries to power data centers, followed in March 2026 by a 12 gigawatt-hour deal with Crusoe Energy for AI data center power. Form Energy is reportedly pursuing a ~$500 million pre-IPO financing round, positioning for a public listing as its commercial momentum accelerates.

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.
