 Rush Island Energy Center (13 cents and 17 cents per share, respectively);

•increased retail electric sales volumes at Ameren Missouri, excluding customer energy-efficiency programs, primarily due to warmer July temperatures and colder winter temperatures compared to the prior-year periods, and growth in retail electric sales (estimated at 15 cents and 17 cents per share, respectively);

•increased base rate revenues at Ameren Missouri for the inclusion of previously deferred interest charges pursuant to the April 2025 MoPSC electric rate order effective June 1, 2025, and higher interest deferrals related to infrastructure investments associated with the PISA and RESRAM (4 cents and 13 cents per share, respectively);

•increased rate base investments at Ameren Transmission and Ameren Illinois Electric Distribution (5 cents and 11 cents per share, respectively); 

•the absence of the October 2024 FERC order reducing the allowed base ROE for FERC regulated transmission rate base and required refunds for certain prior periods under the MISO tariff, which increased Ameren Transmission earnings (4 cents per share for both periods); and

•a higher allowance for equity funds used during construction at Ameren Transmission (4 cents per share in the nine months ended September 30, 2025).

Earnings per diluted share were unfavorably affected in the three and nine months ended September 30, 2025, compared to the year-ago periods, by:

•increased financing costs primarily due to higher interest rates on higher debt balances at Ameren (parent) and Ameren Missouri (6 cents and 20 cents per share, respectively);

•increased other operations and maintenance expenses not subject to formula rates, riders, or trackers, excluding a 2024 charge related to the NSR and Clean Air Act litigation discussed above, largely because of higher storm costs, higher energy center maintenance expense, and higher transmission and distribution expenditures for vegetation management costs at Ameren Missouri (6 cents and 9 cents per share, respectively); 

•increased weighted-average basic common shares outstanding resulting from issuances of common shares (3 cents and 6 cents per share, respectively); and

•increased losses related to equity method investments (2 cents and 5 cents per share, respectively).

The cents per share variances above are presented based on the weighted-average basic common shares outstanding in the three and nine months ended September 30, 2024, and do not reflect the impact of dilution on earnings per
