AMEREN CORP has recently released its 10-Q report. Ameren Corporation is a public utility holding company based in St. Louis, Missouri, with subsidiaries that operate rate-regulated electric generation, transmission and distribution, as well as natural gas transmission and distribution businesses. Its operations are organized into four segments: Ameren Missouri, Ameren Illinois Electric Distribution, Ameren Illinois Natural Gas, and Ameren Transmission.
Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
Ameren said its primary assets are equity interests in its subsidiaries, and those subsidiaries are separate legal entities with separate businesses, assets, and liabilities. Dividends on Ameren common stock and the payment of Ameren-level expenses depend on cash distributions from those subsidiaries. Ameren Missouri operates electric generation, transmission and distribution, plus natural gas distribution in Missouri; Ameren Illinois operates electric transmission, electric distribution and natural gas distribution in Illinois; and ATXI operates a FERC-regulated electric transmission business in the MISO.
For the three months ended June 30, 2026, net income attributable to Ameren common shareholders was $314 million, or $1.13 per diluted share, up from $275 million, or $1.01 per diluted share, a year earlier. For the six months ended June 30, 2026, net income was $671 million, or $2.41 per diluted share, compared with $564 million, or $2.08 per diluted share in the prior-year period.
Ameren said the quarterly and year-to-date increases were driven by higher infrastructure investment across all segments, including infrastructure reflected in electric and natural gas service rates at Ameren Missouri effective June 1, 2025 and September 1, 2025, and natural gas rates at Ameren Illinois effective December 2, 2025. Those gains were partly offset by higher other operations and maintenance expense at Ameren Missouri, mainly from energy center maintenance and vegetation management.
Ameren invested $2.7 billion in its rate-regulated businesses during the first six months of 2026. The company also said its strategic plan centers on rate-regulated infrastructure investment, regulatory frameworks, energy policy, cost management, and capital allocation.
At Ameren Missouri, in June 2026 the company filed for a $343 million increase in annual electric revenues. The request is based on a 10.25% return on common equity, a capital structure of 52% common equity, a $16.7 billion rate base, and a test year ended March 31, 2026, with pro forma adjustments through an expected true-up date of December 31, 2026. Ameren said the Missouri proceeding could take up to 11 months, with a decision expected by May 2027 and new rates by June 2027.
Ameren Missouri also moved ahead on generation and storage projects. In February 2026, the Missouri commission approved a nonunanimous stipulation and agreement tied to a certificate request for the Big Hollow Natural Gas project, an 800-MW facility, and the Big Hollow Battery Energy Storage project, a 400-MW facility. In the same month, Ameren Missouri acquired the Split Rail Solar Project for about $0.6 billion and placed it in service in June 2026. In May 2026, the commission approved a similar stipulation for the Reform Solar Project, a 250-MW facility. Also in May, Ameren Missouri filed for approval to build the Millcreek, Huck Finn, and Castle Bluff battery storage projects, with capacities of 250 MW, 200 MW, and 95 MW, respectively, and to acquire the Ringer and Tom Sawyer solar projects after construction. In July 2026, it filed for approval of the West Alton Natural Gas Project, a 2,100-MW facility.
Ameren Missouri also signed electric service agreements in 2026 with large load customers under its modified large primary service tariff approved in 2025. Those agreements represent 2.8 gigawatts of demand expected to begin materializing in the second half of 2027 and reach full capacity by the end of 2029. Ameren said it does not expect a material impact in 2026 from those agreements.
The company updated its Smart Energy Plan in February 2026, outlining five years of capital spending and a detailed 2026 plan. The plan calls for about $20.8 billion of investment from 2026 through 2030, with most of the spending expected to be recoverable under the PISA before being included in base rates.
Ameren Illinois’ electric distribution business continued to operate under the ICC’s December 2024 order approving revenue requirements of $1,206 million for 2024, $1,287 million for 2025, $1,367 million for 2026, and $1,421 million for 2027. In May 2026, the Illinois Appellate Court upheld that order, along with ICC orders from June 2024 and December 2023. Ameren Illinois later withdrew an appeal of a December 2025 reconciliation order after the appellate ruling.
In April 2026, Ameren Illinois filed a 2025 electric distribution reconciliation adjustment. In June, ICC staff recommended recovery of $31 million, and in July Ameren Illinois filed a revised adjustment consistent with that recommendation. Ameren said the filing reflects actual 2025 recoverable costs, 2025 year-end rate base, and a capital structure of 50% common equity. A decision is due by December 2026, with any approved adjustment to be collected in 2027.
Ameren Illinois also filed an electric energy efficiency plan in May 2026 calling for annual investments of up to $192 million in 2027, $239 million in 2028, and $276 million in 2029. A decision is expected by November 2026.
For natural gas delivery in Illinois, the ICC in November 2025 approved a $79 million increase in annual revenues based on a 9.60% ROE, 50% common equity, a 2026 future test year, and a $3.2 billion rate base. The order also cut $75 million of planned distribution and transmission capital investments. New rates took effect in December 2025. Ameren Illinois appealed that order in January 2026, challenging the treatment of non-service cost components of net periodic benefit income and the capital investment reduction, among other items. Today the company's shares have moved -0.72% to a price of $108.815. For the full picture, make sure to review AMEREN CORP's 10-Q report.
