September 15, 2026 in numbers
NiSource Inc. (ISIN US65473P1057) traded between an intraday low of USD 27.02 and a high of USD 27.58 on the Nasdaq on September 15, 2026. The shares ended the session at USD 27.36, a 0.4% gain, on volume of 2.1 million shares, compared with a recent daily average above 2.5 million. Over the same session, the S&P 500 index declined 0.6%, underscoring that NiSource outperformed the broader market on September 15, 2026. The closing price left the stock around 8% below its 52-week high of USD 29.70 and roughly 12% above its 52-week low of USD 24.40.
According to a US market wrap by Pittsburgh Post-Gazette on September 15, 2026, major US indexes fell as Treasury yields approached 5% and oil prices stayed elevated, weighing on rate-sensitive and utility names. In that environment, NiSource’s small gain reflected relative resilience despite sector pressure. No company-specific earnings or guidance update was released during the session, and the price move tracked broader rate and energy themes highlighted in the market commentary.
Events on September 16, 2026
Today, NiSource has no scheduled quarterly or annual results release within the next few trading days cited in major earnings calendars, and there is no annual meeting or capital markets day noted for September 16, 2026. Broader market events remain relevant: as Bitcoin Magazine reported on September 15, 2026, risk assets showed renewed volatility after a legislative setback for digital asset regulation, adding to the cautious tone across equities. For NiSource, interest-rate expectations and energy price developments continue to matter today given the stock’s exposure to regulated utility operations and fuel costs, even though no company-specific event is due.
