Most Popular Narrative: 10% Undervalued

The most followed narrative puts Alliant Energy’s fair value at $77.09, which sits above the last close at $69.57 and frames the recent pullback in a different light.

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.

Curious what has to happen for that higher fair value to hold up? The narrative leans on steady revenue expansion, fatter margins, and a future earnings profile that assumes regulators and new projects keep cooperating. The exact mix of growth, profitability and valuation multiples might surprise you.

Result: Fair Value of $77.09 (UNDERVALUED)

However, the story can change quickly if large data center projects are delayed, or if regulators in Iowa and Wisconsin take a tougher stance on rate approvals.

Another view on Alliant Energy’s valuation

The narrative fair value of US$77.09 suggests upside from the US$69.57 share price, but the current P/E of 21.9x tells a different story. It is higher than the US Electric Utilities industry at 21.3x, peers at 16x, and even the 21.5x fair ratio estimate, which points to limited valuation cushion if expectations slip.
