NiSource Inc. stock (ISIN US65473P1057) closed at USD 27.36 on the New York Stock Exchange on September 15, 2026, representing a 0.4 percent gain versus the prior session and underlining a steady performance in a volatile US equity market. As of mid-September 2026, the stock price places NiSource within its established 52-week trading band, giving investors a relatively stable entry point compared with more cyclical names.

Midyear 2026 figures show earnings growth

NiSource Inc., a regulated natural gas and electric utility holding company, delivered higher adjusted earnings in its most recent midyear results for fiscal 2026, supported by rate relief and ongoing infrastructure investments across its core service territories. According to Ad-hoc-news on September 16, 2026, operating revenue for the second quarter of fiscal 2026, which ended on June 30, 2026, rose to approximately USD 1.60 billion, compared with around USD 1.52 billion in the prior-year quarter, an increase of about 5.3 percent.

In the same midyear report, NiSource highlighted that net operating earnings for the quarter were roughly USD 210 million, up from around USD 195 million a year earlier, which corresponds to year-on-year growth of approximately 7.7 percent for the three-month period ended June 30, 2026. This combination of mid-single-digit revenue growth and high-single-digit earnings growth underscores the impact of regulatory approvals for rate adjustments and the company’s focus on cost discipline and asset modernization in its gas and electric networks.

Half-year trends and 2026 guidance

The midyear figures also show a solid trend on a half-year basis. According to Ad-hoc-news, total operating revenue for the first half of fiscal 2026 reached about USD 3.15 billion, compared with roughly USD 3.00 billion in the first six months of 2025, a historical increase of around 5.0 percent for the six-month period ended June 30, 2026. For investors, this consistency in revenue expansion over both the quarterly and half-year views is a key signal that NiSource’s underlying customer base and regulated asset footprint are delivering predictable cash flows.

Management backed these trends with a reiterated full-year 2026 guidance. As reported by Ad-hoc-news, NiSource’s management continues to project an adjusted earnings-per-share range of roughly USD 1.70 to USD 1.78 for fiscal year 2026. This range reflects expectations about the timing of ongoing rate case outcomes and the pace of infrastructure investments, particularly in areas such as pipeline modernization, grid reliability and safety enhancements.

Market valuation and dividend context

Based on the latest available share count and the USD 27.36 closing price, NiSource’s equity market capitalization is approximately USD 11.0 billion as of September 15, 2026. According to Ad-hoc-news, the stock trades with a profile typical of regulated utilities, where valuation often hinges on the stability of earnings and the sustainability of the dividend rather than on rapid growth.

Dividend statistics add another dimension to the picture. A recent overview of dividend-paying companies lists NiSource with a share price of USD 40.64, a dividend yield of 2.95 percent and an annualized dividend of USD 1.20 per share, alongside a payout ratio of 59.70 percent as of late October 2026. According to MarketBeat, NiSource is included in a list of dividend contenders with a record of regular distributions, although the October 30, 2026 date for the referenced metrics lies beyond mid-September 2026 and therefore serves as forward-looking context rather than a current peg.

Utility sector backdrop and interest-rate sensitivity

In the broader US market backdrop, regulated utilities such as NiSource remain closely tied to interest-rate expectations and bond-market dynamics. Recent commentary on US indices has pointed to bouts of volatility as central bank decisions and inflation data influence discount rates applied to defensive, income-oriented stocks. For example, macro coverage from financial outlets has highlighted how a hawkish tilt in rate communications can temporarily weigh on utility valuations as investors reassess relative value versus fixed-income yields.

These sector-wide forces frame NiSource’s mid-September 2026 trading behavior, where a 0.4 percent gain to USD 27.36 on September 15, 2026 stands out as a modest positive move in an environment that has seen larger swings in more cyclical sectors. For shareholders, the combination of stable price action within the 52-week band, mid-single-digit revenue growth and a reaffirmed 2026 earnings guidance suggests that the stock may continue to trade as a defensive holding rather than a momentum-driven name.

Closing view on NiSource Inc. stock

NiSource Inc. stock last closed at USD 27.36 on the New York Stock Exchange on September 15, 2026, with the move representing a 0.4 percent gain versus the prior trading session and leaving the market capitalization around USD 11.0 billion at that date. With revenue up about 5.3 percent and net operating earnings approximately 7.7 percent higher year-on-year in the second quarter of 2026, the utility’s financial trajectory underpins the current share price and its position as a stable, income-oriented US regulated utility.
