Alliant Energy Corp appears unfavourable from a value investing perspective. The current price of $70.16 is significantly above the GoodMoat Target of $54.62, indicating a negative margin of safety. The P/E ratio is also elevated relative to its own earnings growth and the typical utility profile.

Based on the GoodMoat Investment Framework's valuation assessment, Alliant Energy (LNT) does not present an attractive margin of safety. The primary valuation tool, the Discounted Cash Flow (DCF) model, yields a GoodMoat Target of $54.62. The current price of $70.16 is approximately 28% above this fair value estimate, resulting in a negative margin of safety. According to the framework's MoS bands, this falls into the 'Unfavourable' category, as a positive margin of safety is a core tenet of value investing. The forward P/E of 22.1x also warrants scrutiny. While not an extreme multiple, it is high for a regulated utility with a 9% revenue growth rate and an 11% Return on Equity (ROE). This P/E suggests the market is pricing in stable, low-risk returns but offers little discount for the company's capital-intensive, debt-heavy model, as evidenced by a Debt/Equity ratio of 1.65 and a negative Free Cash Flow Yield of -6.2%. Compared to the sector, utilities often trade at lower P/Es due to their slow-growth, high-yield nature; LNT's multiple appears full. Integrating this with the framework's decision logic, the stock fails the Valuation & Risk Gate due to the lack of a margin of safety and elevated valuation relative to its fundamental growth and returns profile.
