Listen to the news

Alliant Energy (LNT) is back in focus after a recent share move that left the stock down 5.2% over the past month and 9.4% over the past 3 months. Investors are reassessing expectations.

That pullback comes after a softer run in the short term, with the share price sliding over the past week and month, even though Alliant Energy still shows a positive year to date share price return and a higher one year total shareholder return that reflects dividends reinvested.

Scan how Alliant Energy compares with other utilities showing recent pullbacks and potential resilience across a hand picked set of 11 resilient stocks with low risk scores.

After that slide, Alliant Energy now trades at a small discount to one estimate of intrinsic value and a wider gap to analyst targets. Is the market’s caution sensible, or has pricing drifted too far?

Most Popular Narrative: 15% Undervalued

On the most followed view, Alliant Energy screens slightly cheap, with that framework pointing to a fair value of $79.13 against the recent $66.92 close. That gap rests on a very specific growth and data center story.

The accelerating construction and onboarding of large-scale data centers in Alliant's Midwest service areas highlight a strong, sustained uptick in electricity demand, directly linked to population and economic growth in the region, which is expected to drive significant increases in revenue and top-line growth over the next several years.

The company's adaptive resource planning and regulatory flexibility in Iowa and Wisconsin allows rapid deployment of new generation capacity, positioning Alliant to capture higher allowed returns and efficiently expand its regulated asset base, supporting long-term earnings growth and margin expansion.

Result: Fair Value of $79.13 (UNDERVALUED)

Still, the bullish Alliant Energy story relies heavily on large data center deals and supportive regulators, and any delay or pushback could quickly weaken that thesis.

Another View on Alliant Energy’s Price Tag

There is a wrinkle. On earnings, Alliant Energy trades on a P/E of 21.2x, which is higher than both the US Electric Utilities industry on 20.3x and its peer group at 18.8x, even though the fair ratio sits only slightly higher at 21.7x.

That mix of a small discount to the fair ratio but a premium to the sector and peers points to limited room for error rather than a clear bargain. How comfortable are you paying up for this story if the growth narrative softens at all?
