WEC Energy Group (WEC) Q3 2026 earnings review
WEC Energy raises its profit plan, but regular demand stalls
Hot summer weather and data-center construction lifted WEC Energy Group's profit, while underlying electricity demand from traditional customers barely grew. The Midwest utility's third-quarter profit per share rose 42% from a year ago to $1.18, beating its own plan. Chief executive Scott Lauber raised the full-year outlook, though by our math the plan points to $1.08 per share in the fourth quarter.
| Weather-normal electric deliveries (ex-mine & data centers) | +0.4% +1.2% last quarter |
|---|---|
| Revenue | $2,290.6M +8.9% from a year ago |
| Diluted profit per share | $1.18 +42.2% from a year ago |
| Full-year profit per share outlook | Raised $0.06 middle of the range: $5.62 (+6.6% vs 2025 excluding one-offs) |
⚖️ Verdict: 🟢 Bullish
The story got better because WEC finally raised its full-year profit plan after holding it steady for three quarters, backed by rising returns on data-center construction. One caution: strip out the summer heat, and electricity deliveries to regular homes and businesses rose just 0.4%, proving the utility relies almost entirely on giant data centers for growth.
The question now is whether the expanded five-year capital plan comes with enough customer collateral and regulatory support to protect shareholders as debt climbs. Either the data-center contracts lock in premium returns from mid-2027, or credit disputes and Wisconsin rate politics slow the build. The third-quarter call's capital plan and fourth-quarter rate orders will decide.
🐂 Bull Case
Data Center Spending Lifted the Full-Year Plan
WEC Energy Group is building power plants and grid lines for Very Large Customers (VLCs), its tariff class for massive data centers in Wisconsin. The utility earns a regulated return while these projects are under construction. "Largely due to favorable weather and capital investment supported by the VLCs, the company is raising and narrowing its earnings guidance for 2026 to a range of $5.60 to $5.64 per share," WEC said.
- Third-quarter profit per share: $1.18, up 42.2% from a year ago and 24.2% above the middle of its $0.92–$0.98 plan
- Accounting returns on construction (AFUDC-equity): $44.7 million in the third quarter by our math, up 78.1% from a year ago
- Other net income (which holds those construction returns): $49.5 million, more than double last year's $23.8 million
This matters because the construction returns prove WEC is putting money into the ground for data centers on schedule. However, by our math, the new $5.62 full-year midpoint leaves $1.08 per share for the fourth quarter. That implied figure is 23.9% below last year's fourth-quarter profit excluding one-offs ($1.42), showing that the new plan is still cautious.
What to watch: the quarterly filing's breakdown of construction returns and cash returns from bespoke data-center assets. A figure above the second quarter's $61.6 million combined total would show the build-out sped up.
Operating Costs Grew Slower Than Revenue
Chief executive Scott Lauber said third-quarter results benefited from "execution of our capital plan and operating efficiency". While revenue grew 8.9% from a year ago to $2.29 billion on hot summer weather and higher Wisconsin utility rates, everyday operating expenses barely moved. That gap pushed operating margin up by 3.24 percentage points to 24.6%.
- Day-to-day operation and maintenance costs: 26.8% of revenue, down 1.94 percentage points from a year ago
- Depreciation and amortization (wear and tear on grid assets): 17.0% of revenue, down 0.76 percentage points
- Cost of sales (fuel and purchased power): 28.4% of revenue, down 0.47 percentage points
What to watch: fourth-quarter operation and maintenance expenses. Because the implied fourth-quarter profit per share drops sequentially to $1.08, a jump in late-year maintenance spending would explain why management kept a lid on the full-year raise.
Transmission Grid Investments Keep Growing
WEC owns 60% of American Transmission Company (ATC), which operates high-voltage power lines across the Upper Midwest. Earnings from transmission affiliates rose 20.1% from a year ago to $65.8 million in the third quarter, following a 20.6% gain in the second quarter. WEC sent $173.0 million of capital to these affiliates in the first nine months, up 21.5% from last year, turning grid upgrades into steady profit.
What to watch: the multi-year ATC investment allocation in the updated five-year capital package. A rise above the prior $4.1 billion five-year transmission plan would extend this 20% earnings pace.
Positives this quarter didn't test
Two standing growth catalysts were not updated in the third-quarter earnings release and await the conference call or fourth-quarter regulatory filings.
- New data-center customer agreements: whether WEC signs another 400 to 500 megawatt customer under its Very Large Customer tariff by year-end.
- Wisconsin 2027–2028 rate case outcomes: whether the Public Service Commission of Wisconsin approves or settles the requested 9.9% return on equity before rates take effect on January 1, 2027.
🐻 Bear Case
Hot Summer Weather Masked Flat Customer Demand
"Our strong results were driven by warmer-than-normal weather, execution of our capital plan and operating efficiency," Lauber said. Headline retail electricity deliveries—excluding one Michigan iron ore mine and the Wisconsin data centers—rose 3.3% from a year ago, with residential use up 5.1% as households ran air conditioners.
- Weather-normal retail electricity deliveries (excluding the mine and data centers): up 0.4% from a year ago, down from 1.2% in the second quarter and 1.3% in the first quarter
- Large commercial and industrial deliveries (excluding the mine and data centers): up 1.0%, even with the hot weather
- Small commercial and industrial deliveries: up 3.5% on actual weather
This cuts against the impression of broad demand strength. Strip out the summer heat, and electricity use across WEC's 4.8 million traditional homes, shops and factories barely grew. That leaves the company's multi-billion-dollar growth plan resting almost entirely on two data-center customers.
What to watch: fourth-quarter weather-normal retail electricity deliveries excluding the data centers. A reading below zero would mean the traditional customer base is shrinking while WEC builds out the grid.
Building for Data Centers Drains Cash and Adds Debt
Funding the generation and grid build-out consumes all of WEC's operating cash flow and forces the utility to issue new shares and debt. In the third quarter, capital expenditures of $1.24 billion exceeded operating cash flow of $1.20 billion by our math, leaving negative free cash flow of $36.4 million for the quarter.
- Nine-month capital expenditures: $3.32 billion, or 42.6% of revenue, plus a new $170.8 million payment for options to acquire projects
- Total debt: $23.17 billion at September 30, up $859.6 million (3.9%) since December 31, 2025
- Common stock issued: $382.5 million in the first nine months, lifting the diluted share count by 1.0% in the third quarter to 328.8 million
Because the company also paid $930.8 million in common dividends over the first nine months, it relies on bond and stock markets to plug the gap. Interest expense rose 8.1% from a year ago in the third quarter to $241.7 million.
What to watch: full-year common stock issuance in the fourth-quarter report against the $1.1 billion annual plan. Settling the remaining forward equity contracts will add more shares and weigh on per-share profit growth in 2027.
Risks this quarter didn't answer
Five standing operational, credit and regulatory risks were not addressed in the third-quarter earnings release and require the quarterly filing or conference call to evaluate.
- Port Washington data-center collateral: the quarterly filing will show whether the customer posted more security toward the roughly $7 billion peak requirement or advanced its court challenge.
- Illinois pipe replacement pace: the filing will show whether labor shortages continued to slow Peoples Gas capital spending in the third quarter.
- Wisconsin affordability politics: ahead of the fourth-quarter rate decision and governor's race, any local data-center moratoriums or regulatory pushback remain unquantified in the release.
- Solar tariffs and tax rules: the release gives no update on federal solar import duties or safe-harbor tax rules backing WEC's renewable projects.
- Past-due customer bills: balance-sheet credit reserves dipped to $139.9 million from $148.7 million at year-end, but the 90-day past-due aging table awaits the quarterly filing.
👓 Other Themes
Geopolitical and Fuel Price Risks Stay on the Radar
In its forward-looking statements, WEC again flagged geopolitical tensions, including "the war with Iran" and government trade policies, as risks to supply chains and fuel prices. While utilities pass fuel costs through to customers, sharp swings in natural gas prices or transformer availability can delay construction schedules and inflate customer bills during rate reviews.
💲 Other KPIs
Cash generated from operations rose 15.5% from a year ago in the first nine months, up from a 9.7% pace at the half-year mark. A $587.8 million cash inflow from collecting customer receivables and unbilled revenues drove the improvement and helped cover 9M capital spending of $3,318.7 million.
Net physical utility assets grew by $2.51 billion, or 6.6%, over the first nine months of 2026 from $38.28 billion at year-end 2025. As WEC builds power plants and grid lines for Wisconsin customers, this expanding asset base is what earns the utility's regulated profit in future years.
🔮 Guidance
Raised. The utility lifted the middle of its full-year plan by 6 cents to $5.62 per share, or 6.6% growth over last year's $5.27 profit excluding one-offs, after holding the range unchanged for three quarters. By our math, that leaves $1.08 per share for the fourth quarter, down 23.9% from last year's $1.42 excluding one-offs, assuming normal weather.
❓ Key Questions
How big is the new five-year capital plan?
Management previously committed to updating its $37.5 billion five-year investment plan on the third-quarter call, including power plant replacements and transmission. The earnings release did not include the new dollar total.
Why does the outlook imply a lower fourth quarter?
By our math, the raised full-year outlook leaves $1.08 per share for the fourth quarter, down 24% from last year's $1.42 excluding one-offs. Investors need to know how much of that drop is planned maintenance versus caution.
How much collateral has the Port Washington customer posted?
Construction returns keep rising, meaning WEC is spending heavily on data-center infrastructure. Management has not yet stated in the release how much security the customer has posted toward the roughly $7 billion peak requirement.
Why did weather-normal electric growth slow to 0.4%?
Excluding the iron ore mine and data centers, weather-adjusted electricity deliveries slowed from 1.3% in the first quarter and 1.2% in the second to 0.4% in the third. Management should explain if traditional industrial demand is weakening.
