To fund the transaction, Hubbell tapped into a diverse array of financial instruments. The company secured a $900 million unsecured term loan facility, issued $1.9 billion in senior notes, and utilized proceeds from commercial paper sales. This aggressive capital strategy comes shortly after Hubbell first disclosed its intentions to acquire NSI last month.

Headquartered in Huntersville, NSI brings more than 15,000 branded components to the table, including specialized electrical fittings, connectors, and wire management systems. These products, marketed under the Bridgeport, Polaris, and Tork brands, reach end users primarily through contractors and third-party distributors.

The sale marks a rapid exit for Sentinel Capital Partners, which acquired NSI in 2024. During its brief tenure, the private-equity firm streamlined NSI’s operations by offloading its HVAC division to Lennox International for $550 million earlier this year, effectively concentrating the company’s value into the electrical products segment Hubbell sought to purchase.
