Last week Nexans spent $800 million to enter the US electrical distribution wire / cable business with their acquisition of Republic Wire. This week we start with the news that Hubbell made the largest acquisition in many years, sending $3 billion, in cash, to acquire NSI.

As many know, NSI was on its third private equity firm having been acquired by Sentinel Partners in November 2024, a short 17 months ago (it will be 18-19 by the time the deal closes)

After selling NSI’s HVAC division for $550 million to Lennox Industries in October 2025 and hence recouping a significant percentage of the acquisition cost, the company made some prudent infrastructure investments, added a little bit of acquisition volume, and then empowered the management team to grow the business to the reported $570 million in revenues per the press release.

Perhaps emboldened by the acquisition of Arlington Industries or perhaps unsolicited interest, or maybe the opportunity to redeploy capital into other industries, Sentinel entertained offers and decided to sell the business. Perhaps a little earlier than many expected.

What was a surprise is that Sentinel received the strongest offer from a strategic buyer – Hubbell. Most recently, private equity was expected to win deals as they were willing to outbid strategics.

For Hubbell, the $3 billion represents a 15.5x EBITDA and a 5.26x reported revenues! With being able to outbid PE it is assumed that Hubbell expects significant synergies.

Hubbell Wins NSI

According to a press release,

” Hubbell Incorporated (NYSE: HUBB) today announced it has entered into a definitive agreement to acquire NSI Industries, a portfolio company of Sentinel Capital Partners and a leading provider of electrical fittings, connectors, components, and wire management products, for $3.0 billion in cash, subject to customary adjustments.

“We are excited to add a high growth business in NSI to Hubbell’s Electrical Solutions portfolio,” said Gerben Bakker, Chairman, President, and CEO. “As electrification megatrends drive attractive growth across the electrical industry over the next several years, NSI offers highly complementary products and industry-leading brands to our HES portfolio across strategic growth verticals including light industrial, datacenter, and network infrastructure applications. The acquisition of NSI fits clearly with our long-term strategy to grow our offering of critical infrastructure solutions to our core electrical and utility customers.”

Mark Mikes, President of Hubbell Electrical Solutions, added, “NSI has demonstrated strong organic growth in line with higher growth areas of our HES portfolio over the last several years, and its operating margins are expected to be accretive to the segment. As we continue accelerating our successful segment unification strategy over the next several years, we are confident that the addition of a high growth business in NSI will provide enhanced opportunities for cross-selling, channel conversions, growth across strategic verticals and manufacturing efficiencies.”

NSI anticipates 2026 revenue of approximately $570 million. Hubbell expects the acquisition to be accretive to adjusted EPS in 2026.

The transaction is anticipated to close in mid-2026, subject to the satisfaction of customary closing conditions, including receipt of required regulatory approval. Hubbell plans to finance the transaction with a combination of cash on hand and debt and has obtained fully committed bridge financing from JPMorgan Chase Bank, N.A., Bank of America, N.A., and HSBC Bank USA, N.A. subject to the agreed-upon terms and conditions among the foregoing parties and Hubbell.”

Marketplace Feedback

In conversations with some manufacturers and reps, feedback included:

• Crazy
• Holy smokes seems pricey to me … reps are in trouble.
• Excellent purchase that really rounds HEP out
• Wow! That’s big.
• Don’t you think that Hubbell paying 15.5 times estimated 2026 EBITDA seems a little rich? Most of what NSI has is “me 2”? I know they own the diecast market but still.
• Adding NSI to the Hubbell portfolio is step in the commercial direction for Hubbell in my opinion. It is a good fit for the industrial brand to move into markets they don’t currently own. It will be a complex rep / channel effort for them.

Thoughts on the Deal

• It will be interesting to see how Hubbell handles the integration. IT and support roles will be integrated / absorbed first. Then the question becomes, “how to go to market?” Will NSI be its own brand of brands under Hubbell Electrical Solutions? Will different brands get absorbed into existing Hubbell brands (someone suggested Bridgeport and Killark could go together; could Bryant, or Hubbell Wiring Devices, integrate Tork?) How can Polaris support both the electrical and utility segments of Hubbell? And it can be assumed that the combined entity will consolidate their national account groups, perhaps with a lower tier to support a brand, if they operate NSI as a separate brand.
• What happens to the rep networks? Do they operate separately? Eventually combine? It took Hubbell awhile to consolidate reps for their One Hubbell strategy. NSI has done similar. Back in July, when Yusen disrupted the New England market, I referred to 7 conglomerates that created challenges for rep assignments. There is now one less owner of a conglomerate … or do we? It will be interesting to see how long it takes for this to be addressed. Reps will be on pins and needles for awhile until there is unambiguous decisions by Hubbell. As someone pointed out, Mark Miles commented Hubbell will “continue accelerating our successful segment unification strategy.” Is this code for rep consolidation? Who wins, who loses, what should a rep do. This deal will have ripple effects relative to rep consolidation or a number of line changes.
• The Bridgeport line is a strong stock and flow business. Interestingly, this is at least the second time that Hubbell has tried buying Bridgeport. They were actually the winner when Bridgeport originally sold but then Hubbell, after winning, decided to back out, and the family sold to NSI. Interesting how “the world turns.”
• I saw some things where parts of the deal ae justified by stating that this will increase Hubbell’s data center revenue, and somewhat similar for the utility segment. Really? While NSI has won some data center business, realistically, what percentage of NSI sales are to data centers? According to distributors, this is “smoke and mirrors.” (But, then again, need to posture to Wall Street (the stock was only up 1.5% on Monday.)
• The deal helps gain Hubbell more visibility to the commercial market and is a “good fit for an industrial brand,” so a diversification move, albeit the commercial market isn’t exactly booming. Within the industry, NSI has been growing aggressively, taking share from competitors.
• “With Hubbell now having both die cast and the full range of steel fittings they already offered, it will be worth watching how they leverage that combined product line.” Competitors and distributors will both be watching this. Distributors don’t like being leveraged (except when they can profit from it … rebates, discounts … and competitors will seek to combat this as “specialists” or it could fuel some other acquisitions / sourcing.
• A key to NSI’s growth, according to a rep, has been “their flexibility and willingness to be easy to deal with. I expect it will be the #1 thing that will likely change.”
• Buried within NSI is an electronic business – Lynn Electronics and ENET. It will e interesting to see if Hubbell sells this business or seeks to enter the electronics segment, perhaps positioning it as a data center offering (which would require acquisitions to support this business.)

Overall, an interesting marriage. NSI joins the 72 product brands that Hubbell currently has. Additionally, seemingly there is a difference in cultures and that could determine how successful this acquisition is. In the words of one industry veteran, “Overall, this feels like a very logical acquisition that stays close to Hubbell’s core. The upside will come down to how effectively they integrate the product lines and, more importantly, how they choose to go to market.”

A major investment, and commitment, by Hubbell. The first decision is, “what culture does Hubbell want” followed by should NSI be a “standalone business or integrate the electrical businesses.”

Congratulations to Sentinel for optimizing their return. To NSI in making themselves so desirable and to Hubbell on winning the business.
