What does Ameren Corporation (AEE) do?

Ameren Corporation is a St. Louis based utility holding company that delivers electricity and natural gas to roughly 2.5 million electric and 900,000 gas customers across a 64,000 square mile footprint in Missouri and Illinois. It reports four segments. Ameren Missouri is a vertically integrated utility that owns generation (including the Callaway nuclear plant, coal units at Labadie, and a growing fleet of gas, solar and storage) and sells power under rates set by the Missouri Public Service Commission. Ameren Illinois Electric Distribution and Ameren Illinois Natural Gas are wires and pipes businesses regulated by the Illinois Commerce Commission. Ameren Transmission owns high-voltage lines inside the MISO grid under federally regulated (FERC) formula rates. Because almost all earnings come from allowed returns on invested capital, the company grows by investing in its rate base and getting that spending into customer rates.

The 2026 results so far are ahead of last year. Second-quarter GAAP EPS was $1.13 versus $1.01 a year earlier (consensus ~$1.06), and first-quarter EPS of $1.28 beat ~$1.17, putting six-month earnings at $2.41 per share versus $2.08. Second-quarter segment earnings rose at Missouri (~$157 million), Transmission (~$96 million) and Illinois Electric (~$70 million). Management reaffirmed 2026 EPS guidance of $5.25 to $5.45 and a 6% to 8% annual EPS growth target through 2030, saying it expects to land near the upper end and to update long-term guidance with third-quarter results, scheduled for November 5, 2026, where consensus sits near $2.29 per share against $2.17 a year ago.

The investment picture is a utility being repriced by load growth. Ameren Missouri has signed electric service agreements for ~2.8 gigawatts of large-load demand, largely data centers tied to Google and Amazon projects, with material sales expected from the second half of 2027. That supports a ~$31.8 billion five-year capital plan and ~10.6% projected rate base growth from 2025 to 2030. The offsets are financing (roughly $4 billion of planned equity issuance), affordability pushback on a pending ~$343 million Missouri rate request, and a valuation that already sits above the sector average. At ~$108.15 on October 27, 2026 (market cap ~$29.9 billion), the shares are ~9% below the June high of $118.32 and ~12% above the 52-week low.

What's driving Ameren Corporation (AEE)?

1. Data center load in Missouri

The biggest change in the Ameren story is demand. Ameren Missouri executed electric service agreements with large-load customers totaling ~2.8 gigawatts in 2026, and management cited ~3.4 gigawatts of construction agreements and another ~4 gigawatts of projects that have completed interconnection studies. The September 2026 integrated resource plan projects load growth of ~2.9 to 3.9 gigawatts by 2030 and 6 to 9 gigawatts by 2045. Under Missouri Senate Bill 4 and the approved large-load tariff, those customers are meant to pay the full cost of the power and infrastructure they drive. Material sales are expected from the second half of 2027, so the earnings effect is mostly ahead.

2. A larger capital plan and rate base growth

Utility earnings scale with rate base, the regulated asset value a utility earns a return on. Ameren's February 2026 plan calls for ~$31.8 billion of infrastructure investment over five years, roughly 21% more than the prior plan, supporting ~10.6% compound annual rate base growth from 2025 to 2030. The Missouri Smart Energy Plan alone accounts for ~$20.8 billion from 2026 to 2030, and the broader investment pipeline exceeds $71 billion through 2035. Management has said it will update long-term guidance on the third-quarter call, and the new resource plan (about 10.6 gigawatts of new gas, plus solar, wind, storage and potential nuclear over 20 years) points to more spending, not less.

3. New generation in Missouri

Serving data centers requires new supply. The Missouri commission approved certificates in February 2026 for the ~800 megawatt Big Hollow natural gas plant and a ~400 megawatt Big Hollow battery storage facility. The preferred resource plan adds ~1,900 megawatts of simple-cycle gas by 2029, ~2,100 megawatts of combined-cycle capacity by 2031 and more by 2035, plus fuel cells, solar and storage, while keeping two Labadie coal units running until 2042 rather than 2036. Because Ameren Missouri is vertically integrated, owned generation goes into rate base, which is a key difference from wires-only peers. The Callaway nuclear plant also gives the system a large carbon-free baseload unit, with a license extension under consideration.

4. Transmission and Illinois wires

Ameren Transmission earned ~$96 million in the second quarter of 2026, up from ~$86 million, and operates under FERC formula rates that update annually and have historically allowed higher returns than state-regulated distribution. MISO's long-range transmission planning has assigned Ameren a meaningful slate of new high-voltage projects in Illinois and Missouri, which are expected to build over the rest of the decade. In Illinois, the electric distribution business runs under a multi-year rate plan with annual reconciliations; second-quarter earnings there rose to ~$70 million from ~$64 million. Together these segments diversify Ameren away from a single state commission and add steady, formula-driven rate base growth beside the Missouri buildout.

What are the risks to Ameren Corporation (AEE)?

Regulation is the core risk. Ameren Missouri's June 2026 request for a ~$343 million annual electric increase (10.25% requested return on equity, 52% equity ratio, $16.7 billion rate base) would add ~$13 a month to a typical residential bill, it is the third request in five years after a ~12% increase in June 2025, and a state lawmaker has asked regulators to examine whether data centers are pushing costs onto households. A decision is due by May 2027, and a lower allowed return or disallowed costs would weigh on earnings. Illinois has historically granted below-average returns and has disputed Ameren rate orders through appeals. Data center demand could arrive later or smaller than signed agreements suggest, while the capital plan proceeds regardless. Financing is heavy: roughly $4 billion of planned equity issuance dilutes shareholders, and higher interest rates raise borrowing costs and make the ~2.8% yield less competitive with bonds. Weather swings quarterly results, the gas-heavy resource plan and delayed coal retirements carry environmental and policy risk, and at ~20x 2026 guidance the shares are priced for growth delivery.

What is the Ameren Corporation (AEE) forecast?

18 analysts publish price targets on AEE, averaging $115.06 against a $108.28 price as of October 2026, or +6.3%.

Is AEE a buy or a sell?

We give no verdict on Ameren Corporation. Both cases are real, which is why the question is contested at all, so here is the strongest version of each.

The case for buying. Data center load in Missouri. The biggest change in the Ameren story is demand. The most optimistic published target, $126.00, assumes this works close to its best case.

The case against. Regulation is the core risk. The most pessimistic target, $104.00, is roughly what AEE is worth if this bites instead.

How is Ameren Corporation (AEE) valued? (approximate, October 2026)

A simple financial snapshot. These are approximations and refresh quarterly; for current figures see Ameren Corporation's investor relations page or your broker.

  • Revenue (TTM): ~$8.7 billion
  • Net income (TTM, GAAP): ~$1.56 billion
  • EPS (TTM, GAAP): ~$5.68
  • P/E (TTM / 2026 guidance midpoint): ~19x / ~20x
  • Dividend yield: ~2.8% ($3.00 annual rate)
  • Market cap: ~$29.9 billion

Figures use the ~$108.15 share price on October 27, 2026. Trailing GAAP earnings include tax benefits recorded in 2025; on an adjusted basis trailing EPS is closer to ~$5.36, which puts the multiple near 20x. That is a premium to the broad regulated utility group, reflecting Ameren's above-average rate base growth target. The shares trade at ~2.2x book value. The quarterly dividend is $0.75 after a 5.6% raise in February 2026, with a stated payout target of 50% to 60% of earnings. Analysts' mean target was ~$115 in mid-October, with 13 buy and 9 hold ratings.

Who competes with Ameren Corporation (AEE)?

Midwest regulated utilities

Evergy (the other big Missouri utility, in Kansas City), WEC Energy, Xcel Energy, Alliant Energy, CMS Energy and DTE Energy share Ameren's model: state-regulated rate base growth in the central US, mid-single-digit to high-single-digit EPS targets, and rising data center interest. They are the natural valuation comparison for Ameren's multiple and dividend yield.

Large diversified US utilities

Duke Energy, Southern Company, American Electric Power, Dominion and NextEra Energy are much larger and compete for the same utility-sector capital. AEP and Dominion in particular are also chasing data center load, so investors compare Ameren's signed gigawatts, capital plan growth and regulatory climate against theirs when deciding which utility growth story to own.

Illinois and transmission peers

Exelon, through ComEd in northern Illinois, operates under the same Illinois Commerce Commission and multi-year rate framework as Ameren Illinois, making it the closest read on Illinois regulation. Transmission owners in MISO, such as ITC Holdings (owned by Fortis) and Xcel, compete for and share in the regional high-voltage projects that feed Ameren Transmission's growth.

FAQ

What does Ameren do?

+

Ameren is a regulated utility holding company headquartered in St. Louis. It delivers electricity to roughly 2.5 million customers and natural gas to about 900,000 customers in Missouri and Illinois. Ameren Missouri is vertically integrated, meaning it owns power plants (including the Callaway nuclear plant and the Labadie coal plant) as well as the wires, and it sells electricity at rates set by the Missouri Public Service Commission. Ameren Illinois runs electric and gas delivery networks regulated by the Illinois Commerce Commission, without owning generation. Ameren Transmission owns high-voltage lines in the MISO regional grid under federal oversight. The company earns money mainly through allowed returns on the infrastructure it builds, so its growth depends on how much it invests and how much of that regulators approve for recovery in customer rates.

How did Ameren's latest quarter go?

+

The most recent reported quarter is the second quarter of 2026, released July 30, 2026. GAAP EPS was $1.13, up from $1.01 a year earlier and ahead of the ~$1.06 consensus, and net income attributable to shareholders rose to ~$314 million from ~$275 million. Earnings grew at Ameren Missouri, Ameren Transmission and Illinois electric distribution, while operating revenues dipped to ~$2.09 billion, which is not unusual for a utility where fuel and gas costs pass through to customers. Year to date, EPS was $2.41 versus $2.08. Management reaffirmed 2026 guidance of $5.25 to $5.45. Third-quarter results are scheduled for November 5, 2026, after the close, with consensus near $2.29 per share; the third quarter is seasonally Ameren's largest because of summer cooling demand.

Why are data centers important to Ameren?

+

Data centers are the main reason Ameren's growth outlook changed in 2026. For years, Midwest electricity demand was roughly flat, so utility growth came mostly from replacing aging equipment. Ameren Missouri has now signed electric service agreements covering ~2.8 gigawatts of large-load demand, including projects linked to Google and Amazon with a combined ~$25 billion of planned investment, and has more projects through interconnection studies. Serving that load requires new generation, transmission and substations, all of which can go into rate base and earn a regulated return. Missouri's large-load tariff under Senate Bill 4 is designed to make those customers pay for the costs they cause. The timing matters: Ameren expects material sales to start in the second half of 2027, so most of the earnings effect is still in the future.

Does Ameren pay a dividend?

+

Yes. Ameren pays a quarterly dividend of $0.75 per share, an annualized rate of $3.00, which works out to a yield of ~2.8% at the late October 2026 price of ~$108. The board raised the dividend 5.6% in February 2026 from $0.71, the 13th consecutive year of increases. The next payment is due December 31, 2026 to holders of record on December 8. Ameren's stated policy is to grow the dividend in line with long-term EPS growth (currently a 6% to 8% target) and keep the payout ratio between 50% and 60% of earnings, which is lower than many utilities and leaves more cash to fund the capital plan. That lower payout is one reason the yield is below the utility sector average even as the dividend grows.

Is Ameren stock expensive?

+

By utility standards, Ameren trades at a premium. At ~$108.15 the shares are ~20x the midpoint of 2026 EPS guidance ($5.35), ~19x trailing GAAP earnings and ~2.2x book value, while many regulated utilities trade in the high teens. The premium reflects Ameren's ~10.6% projected rate base growth and management's expectation of reaching the upper end of its 6% to 8% EPS growth target, which is faster than the typical utility. Whether the multiple holds depends on delivery: constructive outcomes in the pending Missouri rate case, data center load arriving on schedule, and equity issuance that does not dilute per-share growth. The mean analyst target of ~$115 in mid-October sits ~7% above the price, with no sell ratings among about 22 analysts.

What is the Missouri rate case and why does it matter?

+

In June 2026, Ameren Missouri asked the Missouri Public Service Commission for a ~$343 million annual increase in electric base rates, based on a 10.25% return on equity, a 52% equity capital structure and a ~$16.7 billion rate base. The utility ties the request to storm hardening, grid upgrades and new generation. It would raise a typical residential bill by about $13 a month. A decision is expected by May 2027, with new rates in June 2027. This matters because Ameren Missouri is the company's largest segment, and the allowed return and the share of spending regulators accept directly set future earnings. Opposition is building: it is the third request in five years, and a lawmaker has asked regulators to examine whether data centers are raising household bills. Most rate cases settle below the request.

What are the biggest risks for Ameren shareholders?

+

The main risks are regulatory, financial and execution. Regulators in Missouri and Illinois could grant lower returns or disallow costs, especially as affordability becomes a political issue alongside data center growth. The ~$31.8 billion capital plan requires large borrowing and about $4 billion of new equity, so higher interest rates or a weaker share price raise the cost of funding growth and can dilute per-share earnings. Data center demand could be delayed or smaller than signed agreements suggest. Large generation projects, including new gas plants and potentially nuclear, carry construction cost and schedule risk. Weather swings quarterly results, particularly summer cooling demand in the third quarter. Environmental policy is another variable, since the 2026 resource plan leans heavily on gas and extends two coal units to 2042, which has drawn criticism from advocates.

How can I get exposure to Ameren?

+

Ameren trades on the New York Stock Exchange under AEE and can be bought as whole or fractional shares at most US brokers. It is also a holding in broad utility sector funds such as the Utilities Select Sector SPDR (XLU) and Vanguard Utilities ETF (VPU), in S&P 500 index funds, and in many dividend-growth ETFs, which spread exposure across dozens of utilities instead of one company. Some investors group utilities like Ameren with other beneficiaries of power demand, such as generators, grid equipment makers and transmission owners, in a thematic basket around AI and data center electricity. Each approach changes how much single-company regulatory risk you carry. Walnut can help you track how a holding like AEE fits your portfolio, but it is not an investment adviser and does not tell you what to buy.
