Simply Wall St · 1d ago

NiSource (NI) has stepped back into the spotlight after its latest quarterly update, which showed higher net income, firmer earnings per share, and a renewed push behind a long-term, multibillion-dollar investment program.

Recent trading suggests investors are warming to that message. NiSource’s share price has gained 14.28% over the past month and 5.72% year to date, while its 1 year total shareholder return of 8.68% sits alongside a 5 year total shareholder return of 106.72%, indicating long term momentum that has also been evident in the short term.

After a 14% jump in a month and fresh earnings strength, NiSource now sits at a very different price than it did this summer. Does it make more sense to commit at the current level or wait for a cheaper entry?
