Q1 earnings and new partnerships set the tone
NiSource (NI) set the stage for its stock story this year with Q1 2026 results that showed higher revenue and net income, reaffirmed earnings guidance, and a higher long term earnings growth target.
The company paired those numbers with fresh partnerships with Alphabet and Amazon, plus new fixed rate notes due 2031 and 2036. Together, these moves highlight how NiSource is funding and shaping its next phase of grid and data center related projects.

Most Popular Narrative: 7.4% Undervalued
Analysts see NiSource's fair value at $50.79, which sits modestly above the last close of $47.03 and helps frame the current optimism around its data center and grid build out story.
Strong visibility into multi-year, rate-based capital expenditure (with a $19.4B base plan, plus $2B+ in upside or incremental projects) positions NiSource for 6 to 8% annual EPS growth and compound growth in regulated revenue.
Want to see what sits behind that growth blueprint? The narrative leans on rising data center demand, thicker margins, and a future earnings multiple that is anything but conservative.
Result: Fair Value of $50.79 (UNDERVALUED)
Have a read of the narrative in full and understand what's behind the forecasts.
However, that story can change quickly if regulatory decisions delay cost recovery on the US$19.4b capital plan, or if long term gas demand weakens faster than expected.

Another angle on valuation
Analysts see NiSource as 7.4% undervalued based on their fair value of $50.79. However, the current P/E of 23.4x sits above the global integrated utilities average of 18.5x, the peer average of 22.5x, and even the 23x fair ratio. This points to a richer pricing that could limit upside if sentiment cools.
For many investors, the real question is whether to trust the earnings narrative that supports that premium or treat the gap to the fair ratio as a warning signal that expectations leave less room for error, especially with heavy capital needs still ahead.
