Per reference figures published in mid September 2026, NiSource stock was recently quoted around USD 40.88 on the New York Stock Exchange, and at that level the utility's annual dividend of USD 1.20 per share translates into a yield of about 2.9 percent, as highlighted by Ad-hoc-news.

Recent fundamentals and valuation backdrop
While the latest detailed quarterly figures are not contained in the most recent week-filtered search results, NiSource's valuation metrics in the S&P 500 overview indicate a price-to-earnings ratio near 21.62 and a related measure around 2.96 as of September 18, 2026, suggesting that the stock is priced at a moderate premium versus some utility peers when measured against earnings and cash-flow related benchmarks in the same table.
These valuation ratios, combined with the dividend yield of about 2.9 percent at a price around USD 40.88 as of mid September 2026, show investors paying roughly 21.6 times trailing earnings for NiSource while receiving a low to mid single-digit cash return, a trade-off that appears consistent with expectations for stable regulated utility cash flows and incremental growth projects, as described in the dividend and ownership context by Ad-hoc-news.
Risk considerations: data center and storm recovery exposure
Recent analysis points to specific risk factors around NiSource, including exposure to data center load trends and storm recovery dynamics in its service territories; shares of NiSource have delivered a gain of only about 3 percent over the past year, which is a modest performance compared with broader equity benchmarks, according to Seeking Alpha.
The same analysis discusses how incremental investment needs for grid modernization and resilience, including storm-related infrastructure reinforcement, could weigh on free cash flow and require careful regulatory engagement to secure timely cost recovery, factors that investors in NiSource Inc. stock currently weigh against the benefits of growing electricity and gas demand from commercial and residential customers, as outlined by Seeking Alpha.
