Second Quarter Diluted Earnings Per Share (EPS) were $1.13 in 2026 vs. $1.01 in 2025
Reaffirmed 2026 Earnings Guidance Range of $5.25 to $5.45 per Diluted Share

ST. LOUIS, July 30, 2026 /PRNewswire/ -- Ameren Corporation (NYSE:AEE) today announced second quarter 2026 net income attributable to common shareholders of $314 million, or $1.13 per diluted share, compared to second quarter 2025 net income of $275 million, or $1.01 per diluted share.

Second quarter 2026 results reflected earnings on infrastructure investments to improve system reliability, resiliency and service quality at each business segment and from investments in innovative energy technology. These positive contributions were partially offset by higher operations and maintenance expenses, primarily driven by increased reliability-focused tree trimming and energy center maintenance. Finally, the earnings per diluted share comparison reflected higher weighted-average basic common shares outstanding in the second quarter of 2026.

"Our second quarter results demonstrate our commitment to delivering value for our customers through consistent execution of our strategy," said Martin J. Lyons, Jr., chairman, president and chief executive officer of Ameren Corporation. "We are investing in a diverse and resilient energy portfolio, strengthening the reliability of the grid and supporting economic growth throughout our region. By focusing on delivering reliable service in a cost-effective way, we are building the energy infrastructure needed to serve our customers today while preparing for the opportunities ahead."

Ameren recorded net income attributable to common shareholders for the six months ended June 30, 2026, of $671 million, or $2.41 per diluted share, compared to net income attributable to common shareholders for the six months ended June 30, 2025, of $564 million, or $2.08 per diluted share. The increase in year-over-year six month earnings reflected earnings on infrastructure investments to improve system reliability, resiliency and service quality for our electric and natural gas customers and from investments in innovative energy technology. These positive contributions were partially offset by higher operations and maintenance expenses, primarily driven by increased reliability-focused tree trimming and energy center maintenance, lower electric retail sales, primarily driven by milder temperatures, and higher interest expense. Finally, the earnings per diluted share comparison reflected higher weighted-average basic common shares outstanding in 2026.

Earnings Guidance

Today, Ameren reaffirmed its 2026 earnings guidance range of $5.25 to $5.45 per share. Earnings guidance for 2026 assumes normal temperatures for the last six months of the year and is subject to the effects of, among other things: regulatory, judicial and legislative actions; energy center and energy transmission and distribution operations; energy, economic, capital and credit market conditions; customer usage; severe storms; returns on market-based and other investments; unusual or otherwise unexpected gains or losses; and other risks and uncertainties outlined, or referred to, in the Forward-looking Statements section of this press release.

Ameren Missouri Segment Results

Ameren Missouri second quarter 2026 earnings were $157 million, compared to second quarter 2025 earnings of $150 million. The year-over-year increase reflected earnings on increased infrastructure investments, including infrastructure reflected in electric and natural gas service rates that became effective June 1, 2025, and September 1, 2025, respectively. These positive factors were partially offset by higher operations and maintenance expenses, primarily driven by increased reliability-focused tree trimming and energy center maintenance, and lower electric retail sales, primarily driven by milder temperatures.

Ameren Transmission Segment Results

Ameren Transmission second quarter 2026 earnings were $96 million, compared to second quarter 2025 earnings of $86 million. The year-over-year increase reflected earnings on increased infrastructure investments.

Ameren Illinois Electric Distribution Segment Results

Ameren Illinois Electric Distribution second quarter 2026 earnings were $70 million, compared to second quarter 2025 earnings of $64 million. The year-over-year increase reflected earnings on increased infrastructure investments.

Ameren Illinois Natural Gas Segment Results

Ameren Illinois Natural Gas second quarter 2026 earnings were $9 million, compared to second quarter 2025 earnings of $10 million.

Ameren Parent Results (includes items not reported in a business segment)

Ameren Parent second quarter 2026 loss was $18 million, compared to a second quarter 2025 loss of $35 million. The year-over-year improvement primarily reflected earnings from innovative energy technology investments.

The following factors, in addition to those discussed within Risk Factors in Ameren's Annual Report on Form 10-K for the year ended December 31, 2025, and elsewhere in this release and in our other filings with the Securities and Exchange Commission, could cause actual results to differ materially from management expectations suggested in such forward-looking statements:

regulatory, judicial, or legislative actions, and any changes in regulatory policies and ratemaking determinations that may change regulatory recovery mechanisms or our ability to recover costs and earn a return, such as those that may result from Ameren Missouri's electric service regulatory rate review filed with the MoPSC in June 2026, Ameren Illinois' 2025 electric distribution service revenue requirement reconciliation adjustment review filed with the ICC in April 2026, Ameren Illinois' January 2026 appeal of the November 2025 ICC order issued in the 2025 natural gas delivery service rate review, and Ameren Illinois' 2020 QIP reconciliation hearing;
