NiSource stock closed at USD 41.51 on the NYSE on September 10, 2026, down 0.4 percent from the prior session. The shares moved in a relatively tight range during the day as US equity benchmarks also ended lower, adding sector pressure to utilities.
September 10, 2026 in numbers
NiSource Inc. (ISIN US65473P1057, NYSE: NI) ended the last completed session on September 10, 2026 at USD 41.51 on the NYSE, modestly below its prior close as trading tracked the broader pullback in US stocks. Per exchange data, the stock’s intraday pattern placed the closing level between the day’s high and low and reflected a measured move rather than an outsized swing in either direction. The S&P 500 also finished lower on September 10, 2026, extending a short losing streak as rising US Treasury yields and higher energy prices weighed on risk assets, which framed NiSource’s decline within a wider risk-off tone in the market.
In sector context, NiSource’s Indiana rate reset remained a focal topic for investors. As Kalkine Media noted on September 10, 2026, the company is weighing an Indiana rate reset, and market participants continue to assess how that process might affect future earnings and allowed returns. At the same time, Jefferies highlighted NiSource among its preferred power and utility names for the fall, arguing that the negative reset scenario is already largely reflected in the valuation; this assessment was reported by Investing.com on September 10, 2026.
Today’s focus for NiSource
Looking ahead to today’s US session on September 11, 2026, NiSource enters the open with fresh attention on its sustainability and regulatory narrative. The company released its 2025 Sustainability Report on September 10, 2026, outlining progress toward a more sustainable energy future and updated environmental and social initiatives, according to a press release cited by Las Vegas Sun. Together with the ongoing Indiana rate reset discussion, these themes may shape sentiment around NiSource today as investors weigh the company’s regulatory trajectory and its positioning within the utility sector amid volatile interest rates and energy markets.
