NiSource (NI)

The company is best known for its natural gas distribution footprint, which makes it one of the larger gas utilities in the country. NiSource delivers gas to residential, commercial, and industrial customers through regulated subsidiaries that operate under state utility oversight. This regulatory structure is central to its business model, as rates, capital investment plans, and allowed returns are generally set through public utility commission processes.

NiSource also operates an electric utility in Indiana, where it supplies power to customers and manages a generation portfolio that includes coal, natural gas, and renewable resources. Like many US utilities, the company is navigating a transition toward cleaner energy while continuing to meet demand and maintain grid reliability. Its investment priorities typically include replacing aging gas pipelines, modernising electric infrastructure, improving safety, and supporting environmental goals.

For investors, NiSource represents a defensive utility stock with exposure to regulated earnings, infrastructure spending, and the energy transition. Its performance is closely tied to regulatory outcomes, interest rates, capital costs, customer growth, and the pace at which it can recover investment through approved rates.
