Ameren has raised its 2026 earnings guidance and set a 2027 target after third-quarter adjusted EPS rose 12% year on year. The US utility also outlined a US$38.1 billion infrastructure programme supporting projected rate-base growth through 2031.
- Third-quarter GAAP diluted EPS increased to US$2.42 from US$2.35
- Adjusted non-GAAP EPS rose from US$2.17 to US$2.42
- 2026 earnings guidance lifted to US$5.35-US$5.55 per diluted share
- 2027 earnings guidance set at US$5.70-US$5.90 per diluted share
- US$38.1 billion infrastructure plan underpins projected 13.3% annual rate-base growth
Ameren Corporation (NYSE:AEE) has raised its 2026 earnings guidance and set a new 2027 target, betting that sustained infrastructure investment and rising electricity demand can support a decade-long growth runway. Third-quarter adjusted non-GAAP earnings per diluted share climbed to US$2.42 from US$2.17 a year earlier, while GAAP diluted EPS rose to US$2.42 from US$2.35.
Guidance rises after stronger nine-month earnings
The St Louis-based utility lifted its 2026 diluted EPS range to US$5.35-US$5.55, from US$5.25-US$5.45. It expects 2027 diluted EPS of US$5.70-US$5.90 and is guiding to compound annual EPS growth of 8% to 10% from 2027 through 2031, using the 2027 midpoint of US$5.80 as the base.
For the nine months to September 30, GAAP net income attributable to common shareholders reached US$1.347 billion, or US$4.83 per diluted share, compared with US$1.204 billion and US$4.43 a year earlier. The prior-year comparison is flattered by a US$48 million tax benefit recorded in the third quarter of 2025; Ameren’s adjusted comparison excludes that item.
Infrastructure investment drives the utility’s growth case
Ameren said higher earnings on reliability and resiliency projects, investments in energy technologies and stronger Ameren Missouri retail electricity sales drove the quarterly improvement. Warmer temperatures also supported Missouri demand. Ameren Missouri earnings rose to US$582 million from US$518 million, while Ameren Illinois Electric Distribution earnings increased to US$72 million from US$57 million.
The company’s longer-term case rests on US$38.1 billion of planned infrastructure investment, which it expects to support rate-base growth of approximately 13.3% annually from 2026 to 2031. Ameren said the programme is intended to meet growing demand from large customers and regional economic development, including potential data-centre demand. That opportunity remains dependent on customer additions, regulatory recovery and the company’s ability to finance and construct the assets.
Higher costs and capital needs remain part of the equation
The earnings increase was not cost-free. Ameren reported higher operations and maintenance expenses, particularly from reliability-focused tree trimming and energy-centre maintenance, alongside higher interest expense over the first nine months. Capital expenditure reached US$4.089 billion in that period, up from US$3.118 billion a year earlier, while long-term debt rose to US$20.443 billion from US$18.214 billion at the end of 2025.
Ameren expects to continue increasing its common dividend, with a payout ratio of 45% to 55% of annual EPS. The guidance assumes normal temperatures and remains exposed to rate-case decisions, project approvals, financing conditions, severe weather, energy prices and the pace of demand from large customers. The company’s Missouri rate review and several Illinois regulatory matters are among the proceedings identified as potential sources of variance.
Bottom Line?
Ameren’s upgraded outlook gives its investment programme greater earnings significance, but the next test is whether regulators, customers and capital markets support the planned build-out without eroding affordability or returns.
Questions in the middle?
- How much of the projected rate-base growth will depend on data-centre and other large-load customers entering Ameren’s service territories?
- Can Ameren recover its rising construction, maintenance and financing costs through regulatory mechanisms while keeping customer rates affordable?
- Will the company’s November 6 analyst call provide more detail on funding requirements, project approvals and the timing of the US$38.1 billion investment plan?
