Ameren Corporation stock was last at USD 99.39 on the NYSE on September 28, 2026, placing it 15.96 percent below its 52-week high of USD 118.32. The latest company plan points to a long investment cycle in Missouri, while analysts have recently trimmed their valuation targets.

Missouri maps long term investment

As Yahoo Finance reported on September 28, 2026, Ameren Missouri published a 20-year Integrated Resource Plan covering natural gas, solar, wind, battery storage, fuel cells and nuclear generation. The plan includes 2,400 megawatts of battery storage by 2030, 1,300 megawatts of new solar capacity by 2030 and 1,200 megawatts of new nuclear generation by 2040.

The roadmap also addresses demand growth. Ameren Missouri has signed electric service agreements covering 2.8 gigawatts of aggregate large-load demand by 2030, according to the same company release carried by Yahoo Finance. That figure gives the plan a commercial dimension beyond generation planning, particularly as new infrastructure must be recovered through regulated utility frameworks.

Quarterly earnings show mixed signals

Ameren's second-quarter 2026 net income attributable to common shareholders rose to USD 314 million from USD 275 million, while diluted EPS increased to USD 1.13 from USD 1.01. StockTitan reported that Ameren reaffirmed 2026 diluted EPS guidance of USD 5.25 to USD 5.45.

The earnings picture was not uniformly positive. Second-quarter revenue was USD 2.09 billion against a USD 2.27 billion estimate, while EPS exceeded the USD 1.08 consensus, according to Investing.com. For investors, the contrast puts infrastructure-led earnings growth alongside execution and demand risks.

RBC lowers its valuation target

RBC Capital lowered its Ameren price target from USD 114.00 to USD 107.00 on September 25, 2026, while maintaining a Sector Perform rating, as Yahoo Finance reported. The move makes valuation a counterweight to the company's expanding investment program and signed large-load demand.
