Memo

ALLIANT ENERGY CORP (LNT). Latest full fiscal year: 2025; data up to 2026-03-31.

Figures computed from the financial statements: revenue 4.4 bn USD in 2025; YoY growth 9.6%; net margin 18.6%; ROE 11.3%; net debt/EBITDA 6.0x.

The estimated value range is 34.07–56.33 USD per share (median of 3 methods, agreement: low); assumptions are illustrative. Against the central value of 49.16 USD, the price of 73.77 USD leaves a potential of -33.4% (value / price − 1) and a margin of safety of -50.0% (1 − price / value). The range is the median of the methods' low, central and high values, not a probability interval.

olivLaw score 29/100, methodological classification: unattractive profile (score, margin of safety and method agreement together; not a judgement of the right price). Not investment advice.

Text generated deterministically from the figures shown; no language model. Not investment advice.

  • EV/EBITDA: 16.2x
  • Dividend yield: 2.8%
  • The price is above the estimated value range

In brief

Alliant Energy is a regulated Midwest utility holding company that supplies electricity and natural gas to customers in Iowa and Wisconsin through its subsidiaries IPL and WPL. The company is in a heavy investment phase in generation and load growth, driven largely by data centers, and it has reaffirmed its 2026 earnings guidance 13. It serves customers on its electric system numbering around 1,010,000, with 2026 ongoing EPS guidance of 3.36 to 3.46 dollars per share 13.

SWOT

Strengths

  • The company has a stable, regulated customer base with predictable revenues from rates approved by regulators, and an extensive portfolio of generation and renewable assets 1.
  • The 2026 guidance has been reaffirmed, and quarterly results point toward the upper half of the range 3.
  • The company has access to conditional federal loan guarantee commitments that could lower the cost of financing large projects 1.

Weaknesses

  • Quarterly results were affected by higher operating, financing and depreciation costs, showing sensitivity to cost pressure 2.
  • Reliance on a few large data center customers increases revenue volatility and counterparty risk 1.
  • Revenues are limited by rules on authorized returns and by refund mechanisms for excess earnings, which can cap upside 1.

Opportunities

  • Growth in data center and industrial load could expand the regulated investment base if projects proceed as planned 12.
  • Investments in gas, storage and renewables can add assets to rates, which could support future earnings growth 12.
  • Development of prepared industrial sites and fiber infrastructure may attract new customers and investment 1.

Threats

  • Community opposition to data centers or legislative restrictions could delay projects and reduce expected load growth 1.
  • Regulatory or legislative changes allowing large customers to self-generate could reduce retail sales 12.
  • Legal uncertainty and environmental rule changes may generate additional compliance costs and affect existing assets 2.

Risks

  • Dependence on data center customershigh

    Large contracts may require investment before revenue is realized, and a customer could reduce or delay consumption, affecting results 1. Concentration risk increases revenue volatility 1.

  • Regulatory decisions and cost recoveryhigh

    Delays or conditions imposed by regulators may limit cost recovery and achievement of authorized returns, which could affect financial results 1.

  • Construction costs and delaysmedium

    Higher material prices, supply chain problems and tariffs may raise the cost of generation projects and delay in-service dates 3.

  • Environmental regulationmedium

    Changes to coal combustion residuals and wastewater rules remain under discussion and the final outcome is uncertain, which could bring additional expenses 2.

  • Weather and demandlow

    Unusual temperatures can materially affect electricity and gas sales, influencing quarterly results 23.

Investment thesis

What would need to be true (bull case)

  • If large data center projects proceed as planned, regulated investment could grow considerably, supporting long-term earnings growth 12.
  • The 2026 guidance has been reaffirmed and results point toward the upper half of the range, which could support investor confidence 3.
  • A portfolio of generation, storage and renewables could provide cost benefits for customers and stability for the company if rates are approved on time 1.

What would break the thesis

  • If large customers delay or reduce consumption, advance investments could earn below expectations and revenues could become volatile 1.
  • If regulators limit cost recovery or impose tougher conditions, authorized returns could be affected 12.
  • Higher construction costs and operating costs could reduce margins and delay project in-service dates 23.

Products, market & competition

AI-generatedAI-generated analysis (Claude) from cited public sources; it may contain errors. Not investment advice. As of 27 Oct 2026 · Model: claude-haiku-5-5.

The business

Alliant Energy Corporation, headquartered in Madison, Wisconsin, is a regulated public utility holding company focused on electricity and natural gas for Midwest customers through its two utility subsidiaries, IPL in Iowa and WPL in Wisconsin 1. These subsidiaries are regulated by the IUC, the PSCW and FERC, which set rates, authorized returns and recoverable costs 1. The company also runs a non-utility portfolio through Alliant Energy Finance, LLC, including interests in ATC, a wind farm, a gas plant and logistics operations through Travero 1.

The strategy rests on three pillars: affordable energy for customers, customer-focused investments in generation and reliability, and growing demand through electrification and attracting large industrial customers 1. The long-term resource plan combines natural gas, energy storage, renewables and upgrades to existing plants, and the company continues to assess how large customer demand affects those plans 1. Medium-term investment has recently expanded through IUC and PSCW approvals for new wind and gas capacity 2.

Financially, utility and corporate services earnings rose in 2025 mainly due to revenue requirements from new capital investment, while in the second quarter of 2026 that segment declined because of higher operating, financing and depreciation costs 12. The company has kept its 2026 guidance and indicates it is trending toward the upper half of the range 3.

Segments

Regulated electric and gas utilities (IPL and WPL)

The regulated segment produces most of the revenue, through retail electric and gas sales to customers in Iowa and Wisconsin plus wholesale sales and transport 1. Retail electric revenues reached 3,305 million dollars in 2025 across the group 1.

Non-utility activities (AEF)

This division includes the ATC stake, a non-utility wind farm, the Sheboygan Falls plant leased to WPL, corporate venture investments, the Travero logistics business and development-ready industrial sites 1. Its results are more volatile and included an asset valuation charge in 2025 1.

Market context

The company operates in Midwest markets where demand is growing, with data centers and large industrial customers becoming an important source of new load, particularly in Iowa and Wisconsin 12. The regulated framework and the MISO market determine wholesale and capacity conditions, and market energy prices can influence purchase costs 1.

The market is dominated by regulated utilities with exclusive territories, where competition mainly comes from energy procurement and from alternative generation that large customers may develop or acquire 1. If such sources expand under rules favoring customers, company sales volumes could be reduced 1.

Trends

  • Data center load growthtailwind

    Signed contracts with data center customers could bring significant sales and rate base growth if projects proceed as planned 12. The risk is that the timing and size of actual load depend on interconnections and real customer demand 2.

  • Regulation of large customer tariffsmixed

    The PSCW has directed WPL to file a large load tariff and the IUC has approved individual customer rates, which may protect existing customers but could also limit company revenues 2. Outcomes may therefore depend on conditions set by regulators 2.

  • Energy transition and environmental rulesmixed

    EPA proposals to narrow the coal combustion residuals rule and revise wastewater limits could reduce compliance costs for existing plants 2. Legal uncertainty and future decisions may nonetheless create additional expenses 12.

  • Supply chain costs and inflationheadwind

    Higher costs for materials, equipment and labor, along with tariffs, can affect the cost and timing of generation and storage projects 3. If these costs exceed estimates, margin pressure could be significant 3.

Competitive position

Alliant Energy operates in regulated territories, so direct competition is limited, and the main pressures come from other regional utilities, alternative electric suppliers and on-site generation that large customers can procure directly 12. Transmission organizations and other generation providers are also relevant to energy price and reliability 1.

The analyzed sources do not give a detailed comparison with exchange-listed peers, but they note that transmission organizations and energy suppliers can influence company results 12. The market also features competition for large customers and for development of industrial land 1.

  • Other Midwest regulated utilities

    Regulated utilities in the same region compete for large industrial customers and economic development, though they are not identified in the source 12.

  • Alternative electric suppliers

    Alternative suppliers and on-site generation could reduce demand for the regulated grid, as described in the risks in the source 2.

  • MISO market operator

    MISO wholesale market and capacity rules influence company revenues and costs, though it is not a direct competitor 1.

  • Regional transmission operators ITC and ATC

    These entities influence transmission load and network investment, affecting the capacity to serve new customers 13.
