GoodMoat Analysis

Based on data as of March 26, 2026

Read full analysis
Based on the GoodMoat Investment Framework's valuation assessment, NiSource's current price of $45.73 is 31% above the GoodMoat Target of $34.93. This results in a negative margin of safety of approximately -31%, which falls into the 'Unfavourable' band according to the framework's DCF-based thresholds (where >40% is deeply undervalued and 20–40% is favourable). The stock's forward P/E of 23.5x is elevated, especially for a regulated utility. It trades above both the typical sector average and its own historical range, which is often lower for stable, slow-growth utilities. This premium is not justified by the company's underlying financials, which show a negative Free Cash Flow Yield of -3.6% and a high Debt/Equity ratio of 1.72. While the company shows a strong operating margin of 27.6%, the combination of a high valuation multiple, negative free cash flow, and significant leverage suggests the stock is expensive relative to its quality and growth profile as a regulated entity. The price implies perfection in execution and rate base growth, leaving no room for error for a value investor seeking a margin of safety. Analysis based on data as of 2024-05-15.
