Ameren (AEE) Q3 2026 earnings review
Ameren raises its growth target, but heat drove its quarter
Power utility Ameren raised its long-term plan for data centers, while hot weather supplied much of this quarter's profit. Profit per share, excluding a tax gain last year, rose 12%. Without the hottest summer in decades and investment gains, it would have risen about 4%, by our math. By our math, the full-year outlook puts fourth-quarter profit about 21% below last year.
| Profit per share, excluding one-offs | $2.42 $2.17 a year ago (+12%) |
|---|---|
| Same, without hot weather and investment gains | +4% $2.18 against $2.10, by our math |
| Yearly growth target for profit per share | 8–10% 6–8% before |
| 2026 outlook | Raised $0.10 middle of the range: $5.45 |
⚖️ Verdict: 🟢 Bullish
The story got better because Ameren turned signed data center contracts into a higher growth target. Chief executive Martin Lyons lifted the yearly goal for profit per share to 8–10%, from 6–8%. One caution: Ameren will sell more shares to fund the build, so per-share profit trails asset growth.
The question now is whether the data centers start drawing power on time. Either their owners begin buying power in late 2027 as planned, or construction delays push the strongest growth past 2029. Missouri's rate decision in May and the first data center sales will tell.
🐂 Bull Case
Ameren Lifts Its Yearly Growth Target to 8–10%
Ameren earns its profit on its rate base, the value of the plants and power lines on which regulators let it earn a return. Chief executive Martin Lyons now expects that base to grow 13.3% a year over the next five years. The plan Ameren published in February assumed 10.6%.
The new plan rests on $38.1 billion of spending, about a fifth more than before. Lyons tied the step-up to 2.8 gigawatts of signed supply contracts with data center builders. The yearly target for profit per share moved to 8–10%, from 6–8%.
Lyons said he has been "appropriately conservative in today's outlook", because the target counts only contracts already signed. The plan for next year supports him: its middle, $5.80 a share, sits 8.4% above where this year's plan started. Growth should run "near the upper end of that range" once data center sales ramp up, Lyons said.
What to watch: new supply contracts beyond the 2.8 gigawatts already signed, which Lyons hopes to add in 2027. Each one would bring sales and spending that the current target leaves out.
More Data Center Projects Moved Toward Signed Contracts
Ameren Missouri signs two kinds of deals with data center developers. In a construction agreement, a developer pays Ameren to connect its site. A later electric service agreement sets its power terms.
Signed service agreements held at 2.8 gigawatts, but the queue behind them moved. About 600 megawatts advanced from engineering studies into construction agreements, Lyons said. That leaves 1.2 gigawatts awaiting a service deal, and Google and Amazon have started building their Missouri sites.
This matters because construction agreements had sat at 3.4 gigawatts for three quarters, so the pool of deals that could sign next was shrinking.
What to watch: another service agreement, which Lyons hopes to see in 2027 but would not date. It would show the queue turning into power sales.
Ameren Wins a Power Line Project in Iowa
Ameren also builds high-voltage power lines and earns a regulated return on them. MISO, which runs the grid across the central US, picks builders for some new lines through contests.
In October, MISO chose a joint bid including Ameren's transmission arm for EASL, a line in Iowa. Group president Michael Moehn called it "our first competitive transmission project award outside of our service territory". Ameren's share is about $500 million.
This matters because Ameren had already won all five contested projects in its own area, so the award widens its field. In the new plan, the value of its lines that earns a regulated return grows 10.7% a year.
What to watch: the next MISO contest, and whether Ameren wins outside its home states again. A second win would show the Iowa result can repeat.
🐻 Bear Case
Hot Weather Drove Most of This Quarter's Gain
Chief executive Martin Lyons said third-quarter results "were driven by continued execution of our strategy and disciplined investment in critical energy infrastructure". Finance chief Lenny Singh noted the quarter "was the warmest in St. Louis in more than 50 years".
- Weather against a normal summer: about +17 cents a share
- Gains on investments in new energy technologies: about +7 cents
- Profit per share without both, by our math: $2.18 against $2.10
Excluding both, profit per share rose about 4% by our math, not 12%. Missouri spent $14 million more on "reliability-focused tree trimming and energy center maintenance". Over nine months, the same math gives about 9%.
What to watch: fourth-quarter profit, when the outlook assumes normal weather and no investment gains. That quarter will show the trend without summer help.
Shareholders Will Fund More of the Bigger Plan
Ameren funds new plants partly by selling shares, so profit per share grows slower than its assets. Chief executive Martin Lyons said "that equity dilution is the primary driver of the difference".
The new plan calls for about $5 billion of share sales, against about $4 billion before. Those sales spread profit over more owners. By our math, the gap between asset growth and per-share growth widened to 4.3 percentage points, from 3.6.
Cash flow adds to the strain: operating cash fell 8.5% so far this year, while Ameren's capital spending climbed 31%.
What to watch: the rating agencies' next reviews. S&P's downgrade line for Ameren sits at 13% for funds from operations against debt, and a reading near it would force more share sales.
Ameren Must Build 7.7 Gigawatts of New Plants
Ameren Missouri's new resource plan adds about 7.7 gigawatts of gas, solar, battery and fuel cell plants within five years. Group president Michael Moehn said "our teams are well positioned to deliver these projects on schedule for our customers".
Turbines for the Castle Bluff gas plant already sit on their pads, Moehn said. Missouri regulators approved five solar and battery projects in October. But the largest, the West Alton gas plant, still awaits approval, and Ameren gave no cost estimate for it.
This matters because the build now exceeds the 5.6 gigawatts planned a quarter ago. Missouri regulators review spending for prudence, so an overrun could go unrecovered.
What to watch: the Castle Bluff gas plant, due in late 2027. An on-time start within budget would support Moehn's case.
Risks this quarter didn't answer
Several standing risks got no decisive new evidence in these results. Each item below names the reading that would move it, and when that reading arrives.
- Data center timing: Ameren expects the contracts "to reach full capacity in 2030", and Lyons named "construction delays at those sites" as the main threat; first sales in late 2027 will show the pace.
- Missouri rate request: $343 million; other parties file testimony on December 4, and regulators decide by May 2027.
- Illinois grid plan: a judge proposed trimming about $212 million; the state commission rules in December.
- Federal tax credits: the build counts on about $2.75 billion of credits; any new federal rule would move this.
- Outlook risk: resolved for now, because the target rose instead of simply rolling forward.
👓 Other Themes
Lower Grid Capacity Prices Cut Pass-Through Revenue
MISO's yearly auction sets capacity prices, the fee for keeping power plants ready to run. The summer price fell to $424 per megawatt-day, from $667. Ameren Missouri's revenue from capacity and spare power sales dropped 13% as a result. Lower fuel and purchased power costs offset that, so sales growth says little about profit here.
💲 Other KPIs
Interest costs rose 3.8% from a year ago, the slowest pace in a year. Growth ran 20% in last year's third quarter and 12% in the second quarter. Ameren books more interest into plants under construction, which holds the expense down while borrowing climbs. Over nine months, the bill is up 10.4%.
The diluted share count, which includes shares owed under forward sales, grew 2.5% from a year ago. The pace has held near that level for three quarters, up from 1.8% a year earlier. Ameren expects to issue about 6.4 million shares near year-end, which will lift the count again.
Customer receivables, the bills customers still owe, rose 7.4% from a year ago, close to revenue growth of 6.8%. Customers kept paying on normal terms despite larger summer bills. The allowance for bad debts reached $47 million, from $38 million.
🔮 Guidance
Raised. The plan now has profit per share near $5.45 at the middle of the range, about 8% above last year excluding one-offs. By our math, that leaves about 62 cents for the fourth quarter. That is roughly 21% less than a year earlier. Finance chief Lenny Singh pointed to more spending on line inspections, tree trimming and plant upkeep. This is the first change after three unchanged updates.
Unchanged in substance. The middle of the range, $5.80, sits 8.4% above where this year's plan started, as Ameren had promised. Against the raised 2026 outlook, growth is about 6%. The forecast assumes normal weather, which removes about 13 cents of this year's heat. Smaller investment gains and more shares also weigh, while new Missouri rates from June 2027 help.
Raised. The yearly target moved up two percentage points and now starts from next year's midpoint. By our math, 9% a year would take profit per share to about $8.19 by the end of the plan. Chief executive Martin Lyons expects the upper end in 2028 and 2029, when data center sales ramp up. The target includes only contracts already signed.
Raised. The five-year spending plan is about 20% larger than February's, mostly for new Missouri gas, solar and battery plants. Power lines won in contests run by MISO, the regional grid operator, add more in later years. The plan covers only the plants needed for 2.9 gigawatts of new demand. Next year alone calls for about $8.8 billion.
Raised. Rate base, the value of assets on which regulators allow a return, would almost double, from $31.7 billion to $59.2 billion. Missouri leads, growing 17.4% a year as new plants enter service. Faster asset growth also widens the gap with per-share profit, because new shares fund part of it.
Raised. Ameren now plans about $5 billion of new shares, mostly near the ends of the next two years. It has already priced about $1.7 billion through forward sales at about $108 a share. Finance chief Lenny Singh said hybrid bonds, which rating agencies treat as half equity, could cover part of the need.
Cut. Ameren now plans to pay out 45–55% of yearly profit as dividends, against 50–60% before. Lyons still expects the dividend to grow every year. The current $3.00 yearly dividend equals about 55% of this year's outlook midpoint. A lower payout keeps more cash for the building program.
❓ Key Questions
How fast will data center sales ramp each year?
Ameren gives a start in late 2027 and full capacity in 2030, but no yearly schedule or expected usage rate. That path decides how much of the faster growth lands in 2028 and 2029.
What will the West Alton gas plant cost?
The 2,100-megawatt plant is the largest project in the plan, and Ameren will oversee its construction with local partners. A cost estimate and contingency would show how much overrun risk shareholders carry.
How close are credit ratios to downgrade levels?
S&P's downgrade line for Ameren sits at 13% of funds from operations to debt. Total debt climbed by $2.7 billion this year, and the plan adds more, so the current ratio matters.
Why does the outlook leave fourth-quarter profit lower?
By our math, the raised outlook implies about 62 cents for the fourth quarter, against 78 cents a year ago. Singh cited higher maintenance spending; a breakdown would show how much is timing.
Which queued projects could sign supply contracts in 2027?
Ameren has 1.2 gigawatts of construction agreements and 4.4 gigawatts of finished studies without supply contracts. Each new contract would add sales and spending that the current target leaves out.
