Alliant Energy’s latest earnings call struck an upbeat tone, blending solid near‑term performance with a visibly accelerating growth engine. Management emphasized strong execution on large customer projects, substantial progress on financing plans and a robust data‑center‑driven demand pipeline, while acknowledging manageable headwinds from weather, higher costs and regulatory noise.

Solid Quarterly Earnings and Guidance Reaffirmed

Alliant reported Q2 2026 GAAP earnings of $0.65 per share and reaffirmed its full‑year guidance. Executives noted that results are currently tracking toward the upper half of the 2026 earnings range, signaling confidence in the company’s ability to absorb near‑term pressures.

Data Center Demand Set to Drive 60% Load Growth

The company highlighted a powerful demand growth story anchored in five executed electric service agreements for large customers. Management expects these deals to support roughly 60% demand growth by 2031, with a broader pipeline representing 2 to 4 gigawatts of future load.

Major Data Center Projects Advance With Tech Giants

Three marquee data center loads are under active construction with Google, QTS and Meta. Google has energized transmission service in Cedar Rapids and QTS’s seven‑building campus there is slated for initial 300 MW energization later this year, while Meta’s Beaver Dam site is in vertical construction.

Additional Capacity and New Iowa Projects

Beyond existing builds, Alliant signed a new 370 MW agreement and plans to file a 900 MW interconnection request for a second Iowa project. These moves deepen the company’s exposure to hyperscale growth and extend its long‑term load trajectory.

Generation Certificates and New Capacity Additions

Alliant is aggressively expanding capacity with filings for the 720 MW Morgan Valley plant, the 1.2 GW Riverhawk simple‑cycle gas project and about 125 MW of energy storage. The company also placed its final two generation enhancement projects at Neenah and Sheboygan into service, unlocking roughly 260 MW of near‑term capacity.

Bobcat and RICE Projects Move Into Construction

Construction has started on the 720 MW Bobcat Energy Center, another simple‑cycle gas facility designed to support data center and regional reliability needs. A separate 95 MW RICE project is under way as well, adding flexible generation that can complement renewables.

Wind and Storage Build‑Out Continues on Schedule

On the renewables front, Alliant secured approval for a roughly 150 MW expansion of the Bent Tree Wind Farm and has moved the project into construction. Other wind, repowering and storage initiatives remain on schedule, reinforcing the company’s balanced resource mix.

Financing Progress Strengthens Balance Sheet Visibility

Management underscored proactive financing actions, with about $1.8 billion of the roughly $2.4 billion common equity needs through 2029 already raised via forward equity agreements. That leaves around $500 million of equity to be secured over the period, alongside remaining 2026 long‑term debt plans of up to $800 million across WPL and IPL.

Grants Reduce Net Capital Requirements

The company also secured around $50 million in grants from the Department of Energy for the Columbia Energy Center and Energy Dome projects. These awards help lower net funding needs and soften the capital burden associated with its decarbonization and reliability investments.

Reliability Rankings Bolster Customer and Regulatory Standing

Alliant’s operational performance earned it the top spot in J.D. Power’s study of large Midwest utilities for power reliability and safety. This recognition supports the company’s case with customers and regulators as it pursues major infrastructure and data center‑related expansions.

Underlying Sales Strength Despite Mild Weather

Temperature‑normalized electric sales climbed about 3% year‑over‑year in Q2, driven by strong commercial and industrial demand in Wisconsin and early data center load ramps in Iowa. This underlying growth helped offset weaker headline margins caused by milder weather.

Weather‑Related Margin Headwinds in the Quarter

Management noted that milder‑than‑normal temperatures trimmed Q2 electric and gas margins by roughly $0.03 per share. That compares with a $0.02 per‑share benefit from weather in the prior‑year quarter, creating a notable swing in earnings impact.

Higher Operating Costs and Timing Effects Weigh on Results

Operating and maintenance expenses rose, reflecting business growth and the timing of generation outages. The company said its O&M assumption has been increased by one percentage point and is weighted toward the first half of the year, contributing to elevated H1 cost levels.

Financing and Depreciation Costs Offset Earnings

Higher financing and depreciation expenses were cited as additional offsets to earnings, tied to the company’s expanding asset base and debt program. With up to $800 million of debt still planned in 2026 and about $500 million of equity to raise through 2029, investors face ongoing financing execution risk.

Regulatory and Political Noise Around Expansion Plans

Executives acknowledged growing regulatory and political scrutiny in Iowa and Wisconsin, including local moratoriums and heightened rhetoric around energy projects. While no current projects are affected, management flagged Federal Energy Regulatory Commission policy on self‑funded network upgrades as a key area to watch.

Project Timing and Earnings Lumpiness

The company cautioned that the timing of load ramps, transmission studies and capital deployment can be lumpy. This could introduce year‑to‑year variability in earnings and make multi‑year EPS growth guidance less precise, even if the long‑term trajectory remains intact.

Tax and Income‑Timing Impacts on Quarterly EPS

Alliant also pointed to the timing of income tax expense as a quarterly headwind. Such timing items can add short‑term noise to reported EPS, underscoring the importance of looking at multi‑year trends rather than single‑quarter swings.

Forward‑Looking Guidance and Growth Outlook

The company reaffirmed its 2026 earnings guidance and reiterated an expected compound annual EPS growth rate of 7% or more for 2027 through 2029. Management plans to update capital expenditure and financing details on the Q3 call, with higher revenues anticipated in 2027–2028 as data center loads ramp and new generation and renewables come online.

Alliant’s earnings call painted a picture of a utility leaning hard into data center‑driven growth while preserving balance sheet discipline. Despite temporary weather, cost and regulatory headwinds, the company’s strong project pipeline, improving sales trends and clear financing roadmap support a constructive outlook for investors watching the utility and infrastructure space.
