Utility and electrical solutions manufacturer Hubbell has reached an agreement to acquire electrical components supplier NSI Industries for $3 billion, the company announced May 4.

Shelton, CT-based Hubbell said the deal will strengthen its position across electrical and utility end markets by expanding its portfolio of infrastructure-related products.

NSI — currently owned by private equity firm Sentinel Capital Partners — manufactures electrical fittings, connectors, components and wire management products used across a range of applications. NSI also serves both electrical and HVAC markets through a portfolio of established brands and sells primarily through distributor channels.

Meanwhile, Hubbell makes a wide range of electrical and utility products, including components for power distribution, grid infrastructure and industrial applications, serving utility, commercial and industrial customers.

Hubbell said NSI’s offerings are highly complementary to its existing Electrical Solutions segment, adding product breadth in key categories and channels.

“As electrification megatrends drive attractive growth across the electrical industry over the next several years, NSI offers highly complementary products and industry-leading brands,” Hubbell CEO Gerben Bakker said in the announcement, noting alignment with growth verticals such as light industrial, data centers and network infrastructure.

The transaction is expected to close in mid-2026, subject to customary approvals. Hubbell said it plans to finance the acquisition through a combination of cash on hand and debt, with committed bridge financing from JPMorgan Chase, Bank of America and HSBC.

Upon closing, NSI will be integrated into Hubbell’s Electrical Solutions segment, further scaling its presence in electrical distribution channels and expanding its offering of critical infrastructure products.
