NiSource (NI): Taking Stock of Valuation After a Strong Multi‑Year Share Price Run

Simply Wall St·12/10/2025 22:19:16
Listen to the news

NiSource (NI) has been quietly grinding higher this year, and its recent pullback after a strong run has some investors asking whether this regulated utility is offering a reasonable entry point.

See our latest analysis for NiSource.

At around $41.44, NiSource’s recent pullback follows a strong year to date share price return, with the 1 year total shareholder return near 16 percent and the 5 year total shareholder return comfortably more than doubling investors’ money. This suggests that momentum is still broadly constructive.

If NiSource’s steady climb has you thinking about what else might be quietly compounding, now is a good time to explore fast growing stocks with high insider ownership.

With solid multi year returns, steady earnings growth and a modest discount to analyst targets, the key question now is whether NiSource still trades below its true value or if the market already reflects its future growth.

Most Popular Narrative: 10.6% Undervalued

With NiSource last closing at $41.44 against a narrative fair value near $46.36, the dominant view sees modest upside still on the table.

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.

Result: Fair Value of $46.36 (UNDERVALUED)

Have a read of the narrative in full and understand what's behind the forecasts.

However, this outlook could be challenged if regulators delay key rate approvals or if long term demand for NiSource’s gas infrastructure weakens faster than expected.

Another View: Market Ratios Tell A Different Story

While the narrative fair value points to upside, NiSource’s 22.1 times price to earnings ratio sits above the global integrated utilities average of 17.9 times, and only slightly below its fair ratio of 22.9 times. That leaves less margin for error if growth or regulation disappoints. Does it really justify a bigger premium?
