ST. LOUIS, Nov. 5, 2026 /PRNewswire/ -- Ameren Corporation (NYSE: AEE) today announced third quarter 2026 net income attributable to common shareholders in accordance with generally accepted accounting principles (GAAP) of $676 million, or $2.42 per diluted share, compared to third quarter 2025 GAAP net income of $640 million, or $2.35 per diluted share. Excluding a third quarter 2025 tax benefit described in the table below, Ameren recorded third quarter 2025 adjusted (non-GAAP) net income attributable to common shareholders of $592 million, or $2.17 per diluted share.

Third quarter 2026 results, compared to adjusted third quarter 2025 results, reflected increased earnings on infrastructure investments to improve system reliability, resiliency and service quality, increased earnings on investments in innovative energy technologies, and higher Ameren Missouri electric retail sales, primarily driven by warmer temperatures. These positive contributions were partially offset by higher Ameren Missouri 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 third quarter of 2026.

"Our third-quarter results were driven by continued execution of our strategy and disciplined investment in critical energy infrastructure to deliver reliable energy for our customers at the lowest cost possible," said Martin J. Lyons, Jr., chairman, president and chief executive officer of Ameren Corporation. "We are well positioned to meet growing energy needs, support significant economic development across our region and deliver lasting benefits for the customers and communities we serve."

Ameren recorded GAAP net income attributable to common shareholders for the nine months ended September 30, 2026, of $1,347 million, or $4.83 per diluted share, compared to GAAP net income attributable to common shareholders for the nine months ended September 30, 2025, of $1,204 million, or $4.43 per diluted share. Excluding a third quarter 2025 tax benefit described below, Ameren recorded adjusted (non-GAAP) net income attributable to common shareholders of $1,156 million, or $4.25 per diluted share for the nine months ended September 30, 2025. Results for the first nine months of 2026, compared to adjusted results for the first nine months of 2025,  reflected higher earnings on infrastructure investments to improve system reliability, resiliency and service quality, higher earnings on investments in innovative energy technologies and higher Ameren Missouri electric retail sales, driven in part by warmer summer temperatures. These positive contributions were partially offset by higher Ameren Missouri operations and maintenance expenses, primarily driven by increased reliability-focused tree trimming and energy center maintenance, and higher interest expense. Finally, the earnings per diluted share comparison reflected higher weighted-average basic common shares outstanding in 2026.

The following items were excluded from adjusted earnings for the three-month and nine-month periods ended September 30, 2025:

Earnings and Rate Base Guidance

Today, Ameren is raising its 2026 earnings guidance range to $5.35 to $5.55 from $5.25 to $5.45 per share. Further, Ameren expects 2027 diluted earnings per share to be in a range of $5.70 to $5.90 per share, representing 8.4% growth from the original 2026 guidance midpoint.

"Our strong year-to-date performance gives us confidence to raise our 2026 earnings guidance. As we look to 2027, we'll continue executing our strategy and investing in energy infrastructure to deliver long-term value for customers and shareholders," Lyons said.

Ameren expects diluted earnings per share to grow at an 8% to 10% compound annual rate from 2027 through 2031, using the 2027 guidance range midpoint of $5.80 per share as the base. Ameren's multi-year earnings growth is expected to be driven by $38.1 billion of planned infrastructure investments underpinning projected rate base growth of approximately 13.3% compounded annually from 2026 through 2031. Ameren expects to continue to grow its common dividend annually, with a payout ratio ranging between 45% and 55% of annual earnings per share.

"Our updated long-term outlook reflects the significant investments needed to serve growing demand from large customers and support economic growth across our region. By strengthening and expanding the energy grid, we can meet that demand while delivering lasting value for our customers, communities and shareholders. We are well positioned to execute our strategy while keeping our customers at the center of everything we do," Lyons said.

Earnings guidance for 2026 assumes normal temperatures for the last three months of the year, and earnings guidance for 2027 and multi-year earnings growth expectations assume normal temperatures. Earnings guidance for 2026 and 2027 and multi-year earnings growth expectations are 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 third quarter 2026 earnings were $582 million, compared to third quarter 2025 earnings of $518 million. The year-over-year increase reflected earnings on increased infrastructure investments, higher electric retail sales, primarily driven by warmer weather, and lower income tax expense due, in part, to timing differences. 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 higher interest expense.

Ameren Transmission Segment Results

Ameren Transmission third quarter 2026 earnings were $110 million, compared to third quarter 2025 GAAP and adjusted earnings of $151 million and $103 million, respectively. Adjusted earnings in 2025 excluded the tax benefit described in the table above. The year-over-year comparison reflected earnings on increased infrastructure investments.

Ameren Illinois Electric Distribution Segment Results

Ameren Illinois Electric Distribution third quarter 2026 earnings were $72 million, compared to third quarter 2025 earnings of $57 million. The year-over-year increase reflected earnings on increased infrastructure investments.

Ameren Illinois Natural Gas Segment Results

Ameren Illinois Natural Gas third quarter 2026 loss was $7 million, compared to third quarter 2025 loss of $13 million. The year-over-year comparison reflected increased infrastructure investments included in natural gas service rates that became effective December 2, 2025.

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

Ameren Parent third quarter 2026 loss was $81 million, compared to a third quarter 2025 loss of $73 million.  The year-over-year comparison primarily reflected higher income tax expense due, in part, to timing differences, and higher interest expense, partially offset by higher earnings from investments in innovative energy technologies.

Use of Non-GAAP Financial Measures

In this release, Ameren has presented adjusted earnings and adjusted earnings per share, which are non-GAAP measures and may not be comparable to those of other companies. A reconciliation of GAAP to non-GAAP information is included in this release. Generally, adjusted earnings or losses include earnings or losses attributable to Ameren common shareholders and exclude income or loss from significant discrete items that management does not consider representative of ongoing earnings. Ameren uses adjusted earnings internally for financial planning and for analysis of performance. Ameren also uses adjusted earnings as the primary performance measurement when communicating with analysts and investors regarding our earnings results and outlook, as the company believes that adjusted earnings allow the company to more accurately compare its ongoing performance across periods. In providing adjusted earnings guidance, there could be differences between adjusted earnings and earnings prepared in accordance with GAAP as a result of our treatment of certain items.
