Listen to the news

NiSource (NI) has drawn fresh attention after its second quarter results showed lower adjusted earnings per share, while management reaffirmed long term targets and highlighted newly approved data center contracts with Amazon and Alphabet.

See our latest analysis for NiSource.

NiSource’s share price has softened in recent months, with a 30 day share price return of down 7.85% and a 90 day share price return of down 10.65%. At the same time, the 1 year total shareholder return of 4.30% and very large 5 year total shareholder return of 96.71% point to much stronger long term rewards and suggest that recent earnings pressure and new data center and funding announcements are being weighed against a longer history of value creation.

After a softer quarter and a recent pullback, NiSource is still leaning into big ticket data center growth and fresh funding. Is that already reflected in the current share price, or is there meaningful upside still on the table?

Most Popular Narrative: 15.3% Undervalued

NiSource’s most followed narrative points to a fair value of $50.03 per share compared with the last close at $42.37. That gap rests on a detailed view of long term earnings and regulated returns.

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.
