Key Terms

private equity, senior notes, prospectus supplement, special mandatory redemption, +4 more

8 terms

private equity financial

"Sentinel Capital Partners, a private equity firm that invests in promising midmarket"

Private equity involves investing money directly into private companies or buying out public companies to make them private, with the goal of improving their performance and increasing their value over time. For investors, it offers an opportunity to earn returns by helping companies grow or restructure, often requiring a longer-term commitment and a higher level of involvement than typical stock investments.

View in glossary

senior notes financial

"priced a $1.9 billion senior notes offering, split into $500 million 4.650%"

Senior notes are a type of loan that a company borrows from investors, promising to pay it back with interest. They are called "senior" because in case the company faces financial trouble, these lenders are paid back before others. This makes senior notes safer for investors compared to other types of loans or bonds.

prospectus supplement regulatory

"[424B2] HUBBELL INC Prospectus Supplement"

A prospectus supplement is an additional document provided alongside a company's main offering details, offering updated or extra information about a specific financial product being sold. It helps investors understand the latest terms, risks, and details of the investment, similar to how an update or revision clarifies or expands on original instructions, ensuring they have current and complete information before making a decision.

special mandatory redemption regulatory

"subject to a Special Mandatory Redemption at 101% of principal plus accrued interest"

A special mandatory redemption is a contractual obligation that forces a company to repay certain debt or preferred shares early when a specific trigger event occurs (for example, a change in tax law, regulatory change, or sale). For investors it matters because it ends the expected income stream and returns principal at a pre-set price, potentially altering returns, tax outcomes and a company’s cash needs — like a lender calling a loan back when rules change.

term loan financial

"entered into a new unsecured Term Loan Agreement to support its planned acquisition"

A term loan is a type of loan that is borrowed for a set period of time, with a fixed schedule for repaying the money, usually in regular payments. It matters to investors because it represents a company's borrowing costs and financial stability; reliable repayment of these loans can indicate strong financial health, while difficulties may signal potential risks.

change of control regulatory

"holders also gain a 101% cash put right upon a change in control triggering event"

A change of control occurs when the ownership or management of a company shifts significantly, such as through a sale, merger, or acquisition, resulting in new leadership or ownership structure. This change can impact the company's direction and decision-making, which is important for investors because it may affect the company's stability, strategy, and future prospects.

restricted stock financial

"received a grant of 341 shares of Common Stock as a stock award. The grant was made at no cash cost per share and is structured as restricted stock."

Shares granted to an individual that carry limits on transfer or sale until certain conditions are met, such as staying with the company for a set time or hitting performance targets. Think of them as a locked gift that gradually opens; for investors they matter because they affect how many shares may enter the market later, signal management incentives and potential dilution, and reveal confidence in future company performance.

deferred compensation financial

"Directors Deferred Compensation Stock Units, each tied to one share of common stock"

Deferred compensation is pay that employees or executives have earned now but will receive at a later date, such as delayed bonuses, retirement benefits, or stock grants. It matters to investors because it creates future obligations and shapes incentives—like a promise to pay later that can affect a company’s reported profits, cash needs and potential stock dilution—so it helps signal how a business manages costs and retains key people.

Value Creation Resulted from Pure-Play Transformation of the Business

NEW YORK, June 9, 2026 /PRNewswire/ -- Sentinel Capital Partners, a private equity firm that invests in promising midmarket companies, today announced the sale of NSI Industries, a leading manufacturer and supplier of branded electrical products, to Hubbell Incorporated (NYSE: HUBB) for $3.0 billion. Sentinel acquired NSI in November 2024.

NSI is a category-leading provider of more than 15,000 branded replenishment electrical power components serving industrial, infrastructure, and commercial end markets. Its core offering of electrical fittings, connectors, components, and wire management products is sold under the iconic brands Bridgeport, Polaris, and Tork via a network of more than 2,000 third-party distributors and contractors throughout North America. NSI has delivered impressive and consistent sales growth, driven by steady, replacement-driven demand and an expanding presence in high-growth end markets, including digital infrastructure and electrification applications like power utilities and data centers.

In October 2025, Sentinel sold NSI's market-leading HVAC division, which included the Duro Dyne and Supco brands, to Lennox International for $550 million. This divestiture refocused NSI as a pure-play manufacturer of branded electrical products.

"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."

"I'm grateful to Sentinel for its leadership and support in transforming our company," said Mike Pruss, NSI's CEO. "We are excited about the growth opportunities for our business and team as part of Hubbell."

Sentinel's deep expertise in electrical manufacturing and distribution includes ECM Industries (electrical products for construction, maintenance, lighting, irrigation, landscape supply, and gas utility markets) and Power Products (diversified electrical products). Sentinel's broader expertise in industrial manufacturing and distribution includes investments in Chromalox (commercial and industrial electric heating products and systems), Engineered Controls (specialized pressure regulators, valves, and other controls), LTI Boyd (engineered sealing and thermal management components), RotoMetrics (rotary tooling products), Sonny's (conveyorized car wash systems and related products), and Spectrum Safety Solutions (fire detection and suppression products).

Lincoln International and Baird are serving as financial advisors to Sentinel, and Kirkland & Ellis is providing legal counsel.
