NiSource Inc. (ISIN US65473P1057) traded at USD 40.33 on the New York Stock Exchange on September 21, 2026, up 1.26 percent over the prior 24-hour period, according to the quoted market snapshot. The price remained within the established 52-week corridor while the company carried a market capitalization of USD 18.75 billion in the same snapshot.

Stock stays inside yearly range

The market data show a mixed short-term picture. NiSource stock was down 4.45 percent over the previous week and 6.38 percent over the previous month, yet it was up 20.42 percent over the previous year as of September 21, 2026. That contrast places the recent move in a longer-term recovery context rather than identifying a one-session breakout.

The valuation frame is also visible in a separate September 22, 2026 filing report. MarketBeat reported that Nykredit invested USD 5.66 million in NiSource and cited a market capitalization of USD 19.42 billion, a price-to-earnings ratio of 21.54 and a PEG ratio of 3.03.

Valuation remains the key measure

For investors, the numerical spread between the two reported market-capitalization snapshots matters: USD 18.75 billion in the September 21 market quote versus USD 19.42 billion in the September 22 filing report. The difference reflects differing timestamps or share-count conventions, so the figures should not be treated as one synchronized market close.

The Nykredit filing adds an ownership signal, but its USD 5.66 million position is small compared with the reported company valuation. The cited beta of 0.54 also points to a lower historical sensitivity than the broader market, while the PEG ratio of 3.03 places greater weight on the earnings-growth assumption embedded in the valuation.
