Hubbell Incorporated (NYSE: HUBB) acquired NSI Industries from private equity firm Sentinel Capital Partners for $3.0 billion, according to a press release statement.

Sentinel originally acquired NSI Industries in November 2024. The company manufactures and supplies electrical products including fittings, connectors, components, and wire management products under brands such as Bridgeport, Polaris, and Tork. NSI distributes more than 15,000 products through a network of over 2,000 third-party distributors and contractors across North America.

In October 2025, Sentinel sold NSI's HVAC division, which included the Duro Dyne and Supco brands, to Lennox International for $550 million. This divestiture transformed NSI into a focused electrical products manufacturer.

"We were honored to partner with the talented team at NSI," said John Van Sickle, a Sentinel partner. "Together, we strategically transformed NSI into a pure-play leader in electrical components, which was instrumental in unlocking value."

NSI serves industrial, infrastructure, and commercial end markets with steady replacement-driven demand and expanding presence in digital infrastructure and electrification applications including power utilities and data centers. The company is headquartered in Huntersville, North Carolina.

Hubbell reported 2025 revenues of $5.8 billion and manufactures utility and electrical solutions. The company's corporate headquarters is located in Shelton, Connecticut.

Lincoln International and Baird served as financial advisors to Sentinel, while Kirkland & Ellis provided legal counsel for the transaction.
