OVERVIEW

Net income attributable to Ameren common shareholders in the three months ended September 30, 2025, was $640 million, or $2.35 per diluted share, compared with $456 million, or $1.70 per diluted share, in the year-ago period. Net income attributable to Ameren common shareholders in the nine months ended September 30, 2025, was $1,204 million, or $4.43 per diluted share, compared with $975 million, or $3.65 per diluted share, in the year-ago period. Net income was favorably affected for the three and nine months ended September 30, 2025, by increased base rate revenues at Ameren Missouri effective June 1, 2025, pursuant to the April 2025 MoPSC electric rate order and decreased tax expense at Ameren Transmission due to the revaluation of excess deferred income tax regulatory liabilities. Earnings were also favorably affected for the three and nine months ended September 30, 2025, by decreased other operations and maintenance expenses not subject to formula rates, riders, or trackers, largely because of the absence in 2025 of an Ameren Missouri charge related to the resolution of outstanding claims in the NSR and Clean Air Act litigation associated with the Rush Island Energy Center. Additionally, earnings were favorably affected for the three and nine months ended September 30, 2025,
