Three Months20252024Net income attributable to Ameren common shareholders$289 $261 Earnings per common share – basic and diluted1.07 0.98 

Net income attributable to Ameren common shareholders increased $28 million and earnings per diluted share increased 9 cents in the three months ended March 31, 2025, compared with the year-ago period. The increase was due to net income increases of $17 million, $17 million, $7 million, and $2 million at Ameren Missouri, Ameren Transmission, Ameren Illinois Electric Distribution, and Ameren Illinois Natural Gas. These increases were partially offset by a net loss of $13 million compared to a net income of $2 million in the year-ago period, for activity not reported as part of a segment, primarily at Ameren (parent).

Earnings per diluted share were favorably affected in the three months ended March 31, 2025, compared to the year-ago period by:

•increased retail electric sales volumes at Ameren Missouri, excluding customer energy-efficiency programs, primarily due to colder winter temperatures in 2025 (estimated at 6 cents per share);

•decreased interest charges resulting from higher deferrals related to infrastructure investments associated with the PISA and RESRAM at Ameren Missouri (5 cents per share);

•increased rate base investments at Ameren Transmission and Ameren Illinois Electric Distribution (4 cents per share);

•decreased other operations and maintenance expenses not subject to formula rates, riders, or trackers due to the absence in 2025 of an Ameren Missouri charge related to the NSR and Clean Air Act litigation associated with the Rush Island Energy Center (4 cents per share); and

•a higher allowance for equity funds used during construction at Ameren Transmission, primarily resulting from a decreased level of short-term borrowings included in the calculation and higher average construction work in progress balances (2 cents per share).

Earnings per diluted share were unfavorably affected in the three months ended March 31, 2025, compared to the year-ago period, by:

•increased financing costs primarily due to higher short-term debt balances at Ameren (parent), and higher debt balances at Ameren Missouri (8 cents per share);

•increased other operations and maintenance expenses not subject to formula rates, riders, or trackers primarily due to higher storm costs at Ameren Missouri (2 cents per share);
