Sentinel Capital Partners announced the sale of NSI Industries, a manufacturer and supplier of branded electrical products, to Hubbell Incorporated in a transaction valued at $3 billion. Sentinel had acquired NSI in November 2024.
Headquartered in Huntersville, North Carolina, NSI supplies more than 15,000 electrical products through over 2,000 distributors and contractors across North America. Its portfolio includes well-known brands such as Bridgeport, Polaris, and Tork, serving industrial, infrastructure, and commercial markets. The company has benefited from steady replacement-driven demand and growing exposure to high-growth sectors including digital infrastructure, utilities, electrification, and data centers.
During Sentinel’s ownership, NSI underwent a strategic transformation. In October 2025, Sentinel sold the company’s HVAC division, which included the Duro Dyne and Supco brands, to Lennox International for $550 million. The divestiture repositioned NSI as a pure-play electrical products business.
Sentinel said the streamlined structure enhanced NSI’s position as a leading provider of electrical components and contributed to the value created during the investment period. Hubbell, which generated $5.8 billion in revenue in 2025, said the acquisition will strengthen its portfolio of utility and electrical solutions.
Lincoln International and Baird served as financial advisors to Sentinel, while Kirkland & Ellis acted as legal counsel.
