 to the absence in 2025 of a charge at Ameren Missouri related to the NSR and Clean Air Act litigation associated with the Rush Island Energy Center (4 cents per share in the six months ended June 30, 2025); and

•increased retail electric sales volumes at Ameren Missouri, excluding customer energy-efficiency programs, primarily due to colder winter temperatures in 2025 compared to the prior-year period (estimated at 2 cents per share for the six months ended June 30, 2025).

Earnings per diluted share were unfavorably affected in the three and six months ended June 30, 2025, compared to the year-ago periods (except where a specific period is referenced), by:

•increased financing costs primarily due to higher short-term and long-term debt balances at Ameren (parent), and higher interest rates on higher debt balances at Ameren Missouri (6 cents and 14 cents per share, respectively);

•decreased retail electric sales volumes at Ameren Missouri, excluding customer energy-efficiency programs, primarily due to milder spring and early summer temperatures in 2025 compared to the prior-year period (estimated at 4 cents per share for the three months ended June 30, 2025); and

•increased weighted-average basic common shares outstanding resulting from issuances of common shares (2 cents and 3 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 six months ended June 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%.
