On May 6, 2026, Hubbell Incorporated signed a definitive agreement to acquire NSI Industries from Sentinel Capital Partners for $3.0 billion. The transaction follows Sentinel’s divestiture of NSI’s HVAC division to Lennox International for $550 million, completing NSI’s repositioning as a pure-play electrical manufacturer.

Hubbell aims to expand its electrical solutions portfolio by integrating NSI’s offerings in fittings, connectors, and wire management products. The acquisition strengthens Hubbell’s reach in industrial, infrastructure, and commercial markets, particularly power utilities and datacenter electrification applications.

NSI Industries manufactures over 15,000 branded electrical products under the Bridgeport, Polaris, and Tork names, distributing through more than 2,000 third-party distributors and contractors. Its replacement-driven demand model and growth in high-growth end markets have driven consistent sales expansion.

Hubbell generated $5.8 billion in revenues in 2025, and the addition of NSI could enhance its revenue base and margin profile. The deal is expected to be accretive to earnings and bolster Hubbell’s long-term growth strategy in electrical infrastructure.
