What does NiSource Inc. do?

NiSource is a regulated utility holding company operating natural gas distribution and electric generation across several U.S. states, primarily through its NIPSCO and Columbia Gas subsidiaries. It recently secured a long-term contract to supply up to 2,400 MW to Amazon data centers by 2032, positioning it at the intersection of traditional utility infrastructure and AI-driven power demand. The stock's recent rally on that contract and Q4 earnings was flagged as low-conviction, making it vulnerable to the kind of sharp reversal now underway.
