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 share, unless otherwise noted. The amounts above other than variances related to income taxes have been presented net of income taxes using Ameren’s 2025 blended federal and state statutory tax rate of 26%.
