Another View: NiSource Through a Cash Flow Lens
The 14.8% gap between NiSource's recent share price of $42.61 and the $50.03 fair value from analyst models suggests some upside based on earnings multiples. However, the SWS DCF model points the other way and indicates a fair value of $36.27, which would put the stock in overvalued territory on that measure.
The two methods are asking different questions. One leans on earnings and market comparisons, while the DCF focuses on the timing and size of future cash flows. Which approach better matches how you think NiSource's long term projects and regulatory profile will show up in actual cash generation?
