NiSource (NI) is in focus after recent share moves, with the stock down about 0.4% on the day and roughly 2.4% over the past week, despite modest gains over the past month.

Looking past the recent pullback, NiSource’s share price return is up 10.67% year to date. Its 1 year total shareholder return of 20.98% and 5 year total shareholder return of 115.19% point to momentum that has built over time rather than faded in recent months.

After NiSource’s pullback against a strong 1 year and 5 year shareholder return record, the spotlight shifts to valuation. Does the current price sit meaningfully below fair value estimates, or does it already reflect most of that optimism?

Most Popular Narrative: 9.1% Undervalued

Based on the most followed narrative, NiSource’s fair value sits at $51.36 versus a last close of $46.66, framing the recent pullback as a valuation gap to watch.

Strong visibility into multi-year, rate-based capital expenditure ($19.4B base plan, plus $2B+ in upside/incremental projects) positions NiSource for 6 to 8% annual EPS growth and compound growth in regulated revenue.

Curious how a heavily regulated utility like NiSource can support that valuation gap? The narrative leans on consistent revenue expansion, higher margins, and a richer future earnings multiple. The exact mix of growth, profitability and discounting is what drives that $51.36 figure.

Result: Fair Value of $51.36 (UNDERVALUED)

However, NiSource’s heavy focus on gas infrastructure and reliance on constructive regulatory outcomes could become pressure points if policies, demand or approvals shift against expectations.

Another View: What NiSource’s P/E Says About Valuation

While one narrative points to NiSource trading about 9.1% below a $51.36 fair value, the P/E picture looks tighter. NiSource trades on a 23.2x P/E, slightly above peers at 23.1x and well above the global integrated utilities average of 19.2x, compared with a fair ratio of 22.2x.

That gap suggests limited valuation cushion. If sentiment shifted toward the 22.2x fair ratio or even closer to the 19.2x global average, today’s price would have less support. The question becomes which version of “fair” you trust when you weigh the risk and potential reward.

Next Steps

All of this mixed sentiment around NiSource, with both concerns and reasons for optimism, is exactly why you should look through the data yourself and decide quickly where you stand based on the underlying 2 key rewards and 3 important warning signs.
