How we got here: the combined value of 5 valuation models built for a business like Alliant Energy (see the models table below and how they are combined) , with a 7% cost of equity. The models span ~$45–~$65; that spread sets a 15% margin before we rate Buy or Sell.

Produced by Fundamentalytics' automated valuation model on November 3, 2026, using delayed market prices. Rating meanings, methodology and conflicts: recommendations disclosure and research disclaimer. General research, not personal advice — it does not consider your circumstances. Prices can fall as well as rise.

Valuation models

We value Alliant Energy as an utility or power producer, with every model that fits that kind of business. Cost of equity 7%: the 10-year Treasury yield (4.9%) plus a beta of 0.43 times a 4.5% equity risk premium.

Value per share by model
Model Value per share In the combined value?
Utility earnings model Net income growing 3% a year, discounted at 8%: for regulated investment that makes free cash flow negative. ~$65 ~$54–$82 Primary model, counts double
Forward price-to-earnings vs peers Next year's consensus earnings per share times peers' typical (harmonic-mean) forward price-to-earnings. Uses analysts' consensus estimates (third-party data), not our forecasts. ~$57 ~$56–$71 Included
Justified price-to-book Book value times (return on equity - growth) / (cost of equity - growth): steady-state returns. ~$57 ~$46–$77 Included
Residual income Book value plus the present value of returns above the cost of equity, fading over ten years. ~$45 ~$32–$65 Included
Dividend discount (two-stage) Dividends for five years at the growth the business can fund, then a steady payout and growth. ~$56 ~$45–$75 Included
Combined value Weighted average of the models that apply: the primary model (utility earnings model) counts double. Models more than 5x or less than 0.2x the share price, or more than 3x away from the other models' median, are left out. ~$58 ~$45–$65 5 models

Different models fail in different ways, so where several apply we average them rather than trust one. Peer-based models compare Alliant Energy with utilities and power producers in our coverage, using third-party market data. Model values are estimates under stated assumptions, updated as new filings arrive; not price targets or investment advice. How each model works.

Moat

55 /100

Moderate moat

How hard Alliant Energy's competitive advantage looks for rivals to wear away, judged from 10 years of its own filings: returns on capital, pricing power, profit durability, cash conversion and discipline.

  • Returns on capital 3 / 20

    Net income has been a median 3.3% of total assets over 10 years.

  • Pricing power 20 / 20

    Gross margin has been a median 85.9%, moving by 0.8 percentage points (standard deviation) across 8 years.

  • Durability 17 / 20

    Operating margin has been a median 21.8%; its worst year was 16.9%.

  • Cash conversion 0 / 20

    Free cash flow was positive in 0 of 8 years, at a median -24.2% of revenue.

  • Discipline 16 / 20

    The diluted share count rose 3.5% over five years; stock-based pay has been a median 0.4% of revenue.

AI disruption exposure: Low. In this industry, the business rests on physical assets, regulated networks or products AI itself depends on.

Options strategies

All options ideas

How Alliant Energy’s listed options are priced, and three ways to use them that follow from our valuation. Quotes are delayed, read November 2, 2026. Check the live chain at your broker before trading.

Cash-secured put

Not offered: rated Sell.

We suggest selling a put only on well-rated companies, at a strike where the price you would pay if assigned (strike less premium) is at or below our fair value.

Covered call

Not offered: no liquid call at or above our price target — the model says the upside is worth more than any listed strike.

For holders: sell a call at a strike at or above our fair value, so the shares are only sold at a price the model calls full value.

Collar

Not offered: no liquid put and call pair for the same expiry.

For holders of a stock trading at or above our fair value: buy a put for a floor and sell a call to pay for it.

General research, not personal advice. Options can lose you more than you expect and are not suitable for everyone: put sellers can be made to buy shares that keep falling, call sellers give up gains above the strike, and results or news can move prices sharply. Chances shown are approximations from each option’s delta. Spreads, fees and early assignment are not modelled.
