Alliant Energy Corp (LNT) Stock Analysis

GoodMoat Analysis

Based on data as of March 26, 2026

Alliant Energy is a regulated electric utility with a stable, predictable business model. While it possesses a durable regulatory moat, its valuation appears unfavourable relative to its estimated fair value and growth profile.

Read full analysis
Alliant Energy Corp operates as a regulated electric and gas utility, primarily serving customers in Wisconsin and Iowa. This business model grants it a durable competitive advantage, or moat, primarily through regulatory barriers. As a regulated monopoly, it operates under a framework where its rates and returns on capital are approved by state commissions, creating high switching costs for customers and a stable, predictable revenue stream. Applying the GoodMoat framework, it would score highly on criteria like Regulatory Barriers and Switching Costs, but likely lower on others like Brand or Network Effects, which are less relevant for utilities. This suggests a solid, though not exceptionally wide, economic moat. From a valuation perspective, the analysis is less favourable. The stock trades at a P/E of 22.1x, which is high for a utility with a 9% revenue growth rate and an 11.0% ROE. More critically, the GoodMoat Target price is $54.62, implying the current price of $70.16 is approximately 28% above that estimate. This negative margin of safety fails the Valuation Gate in the Decision Framework. Furthermore, the negative Free Cash Flow Yield of -6.2% and a Debt/Equity ratio of 1.65 indicate significant capital investment and leverage, which are typical for utilities but limit financial flexibility. For a value investor, Alliant Energy represents a classic, moat-protected utility business. However, its current price does not offer a margin of safety relative to the platform's fair value estimate, making further investigation primarily an exercise in challenging that valuation assumption rather than identifying an obvious opportunity. Analysis based on data as of 2024-05-15.
