Earnings call transcript: Alliant Energy Q3 2025 misses forecasts, shares rise

Alliant Energy (LNT) reported Q3 2025 EPS of $1.09 and revenue of $1.21 billion, missing analyst expectations, yet its stock rose 1.51% to $66.94. This positive market reaction reflects investor confidence in the company's robust growth outlook, as LNT narrowed its 2025 earnings guidance and initiated 2026 guidance with a 6.6% increase, targeting 7-8% earnings growth from 2027-2029. This growth is supported by a 17% increase in its 4-year capital expenditure plan to $13.4 billion, primarily for energy storage and data center expansions, including 3 GW of contracted demand expected to drive 50% peak demand growth by 2030, with a further 2-4 GW in the pipeline.

Analysis

Alliant Energy (LNT) reported Q3 2025 EPS of $1.09 and revenue of $1.21 billion, missing analyst forecasts of $1.18 and $1.32 billion, respectively. Despite these shortfalls, the stock rose 1.51% to $66.94, nearing its 52-week high. This positive market reaction indicates strong investor confidence in the company's strategic direction, outweighing current operational misses.

The company narrowed its 2025 EPS guidance to $3.17-$3.23 and initiated a robust 2026 EPS guidance of $3.36-$3.46, a 6.6% increase over the 2025 midpoint. LNT projects 7-8% earnings growth from 2027-2029, supported by a 17% increase in its 4-year capital expenditure plan to $13.4 billion. These investments target energy storage and data center expansions, with 3 gigawatts of contracted demand expected to drive 50% peak demand growth by 2030.

Alliant Energy is actively pursuing an additional 2-4 gigawatt data center pipeline, leveraging "plug-and-ready" sites and accelerated load ramps, such as with Google. The company benefits from supportive regulatory environments in Iowa and Wisconsin, which provide mechanisms to minimize regulatory lag and ensure authorized returns, aligning with its strategic investment focus.

To fund its ambitious capital plan, LNT anticipates $2.4 billion in new common equity issuances from 2026-2029, with $1.6 billion remaining after forward agreements for 2026, alongside $1.5-$1.6 billion in tax credits. Key risks include execution challenges with large capital expenditures, dependence on sustained data center demand growth, and potential regulatory changes.

Key Decisions for Investors

• Investors should assess LNT's long-term growth trajectory, particularly its 7-8% earnings growth target from 2027-2029, driven by significant data center and energy storage investments, which appear to be the primary driver of current positive sentiment despite recent earnings misses.
• Monitor the execution of the $13.4 billion capital expenditure plan and the successful integration of the 2-4 gigawatt data center pipeline, as these are critical for realizing projected load growth and earnings targets.
• Evaluate the impact of the planned $2.4 billion common equity issuances on shareholder dilution and the company's ability to maintain credit metrics, while also considering the stability provided by supportive regulatory frameworks in Iowa and Wisconsin.
