The Short Version

• Rexel, a giant European seller of electrical supplies, is buying GCG, a Chicago company that supplies specialized wire and cable.
• GCG expects more than $1.1 billion in sales this year. Its customers include data centers, the warehouse-sized buildings full of computers that run the internet and artificial intelligence, plus power networks and the military.
• What Rexel is really buying is expertise: GCG’s engineers design and prepare cable to order for demanding building projects.
• The price has not been made public.

GCG, a Chicago-based specialty wire and cable distributor, announced on September 25, 2026, in a release distributed by PR Newswire, that Rexel is acquiring it from Audax Private Equity. The transaction is expected to close by year end, subject to regulatory approvals and customary conditions. Financial terms were not disclosed.

GCG operates in North America and Europe through 16 locations with more than 950 employees and expects to exceed $1.1 billion in revenue in 2026. Rexel, a publicly held distributor of energy-management products, reported €19.4 billion in 2025 sales across 1,876 branches in 17 countries.

Executive Summary

Rexel is buying a distributor whose selling point is not inventory but engineering. GCG runs two segments, Custom Engineered Solutions and Connectivity & Power Solutions, and describes its model as engineer-led, value-added distribution of wire, cable and connectivity products. Its customers span data centers, power infrastructure, defense, building systems, water, telecom and industrial markets.

Rexel’s stated reasons are specific: to extend its presence in high-growth, mission-critical markets, naming data centers and power infrastructure first, and to bring GCG’s engineering-led model and proprietary product portfolio into its larger platform. That framing matters more than GCG’s size. At just over $1.1 billion in revenue against Rexel’s €19.4 billion, GCG is a targeted capability purchase rather than a transformational one.

The central open question is price. Without a purchase figure, financing details or GCG’s profitability, outsiders cannot judge how much Rexel is paying for data center exposure versus the underlying distribution business.

What Rexel Is Actually Buying: Engineers at the Cable Reel

Electrical distribution is often a volume business: stock common products, run many branches, deliver fast. GCG looks different. It serves more than $1.1 billion in expected revenue from just 16 locations, while Rexel runs 1,876 branches. A small number of specialist sites generating that revenue points to a model built around project work, not counter sales. GCG’s own segment name, Custom Engineered Solutions, and its description of ‘engineer-led, value-added’ service say the same thing.

In cable, value-added distribution typically means work done before the product ships: cutting to specified lengths, assembling or kitting components, and helping customers specify the right cable for a job. On large, mission-critical projects such as data centers and power facilities, cabling is specified to project requirements and delivered on construction schedules, so a distributor that can engineer and prepare it takes on work that would otherwise fall to contractors or manufacturers.

That is the capability Rexel names in its rationale: GCG’s ‘engineering-led, value-added distribution model and proprietary product portfolio.’ Rexel is not describing a need for more warehouse space or more product lines. It is describing a need for engineering capacity attached to cable, aimed first at data center and power customers. The bet is that in those markets, the sale is won on specification and preparation, and that this capability can be scaled across Rexel’s much larger network.

A Small Deal by Size, a Pointed One by Market

GCG’s expected 2026 revenue is well under a tenth of Rexel’s 2025 sales, so this acquisition will not reshape Rexel’s overall results. Its significance lies in direction. When a distributor of Rexel’s scale names data centers and power infrastructure as the markets it wants more of, it signals where it expects demand growth to come from.

That expectation is consistent with the broader construction cycle in data centers, much of it driven by cloud computing and artificial intelligence, which requires large quantities of power and connectivity cabling. The release, however, does not say how much of GCG’s revenue comes from data centers. GCG lists seven end markets, including defense, water and building systems, so its data center exposure could be substantial or modest. Readers should treat the deal as a bet on data center growth, not evidence of how large GCG’s share of that market already is.

The Private Equity Roll-Up Behind the Deal

GCG is the product of a classic buy-and-build strategy. Audax acquired it as a carve-out of Genuine Parts Company’s Electrical Specialties Group, then expanded it through acquisitions including United Wire & Cable, CableMaster, RWL, Paige and Allied Wire & Cable. GCG says it grew to more than $1.1 billion in revenue since 2019 through both organic growth and those add-ons.

For Rexel, that history cuts two ways. GCG has experience integrating acquired businesses and operates through local brands, which suggests customer relationships that sit with those brands. But the release does not separate organic growth from acquired revenue, so the underlying growth rate of the business Rexel is buying is not visible. A roll-up that grew mainly through purchases carries different risks from one that grew mainly by winning customers.

Who Gains, and What Could Go Wrong

Contractors and developers building data centers and power sites could gain a single channel that combines GCG’s engineered cable services with Rexel’s scale, if integration goes as described. Cable manufacturers will see further consolidation among the distributors that sell their products, which can shift purchasing leverage toward larger buyers.

The main risks are concentration and integration. A business positioned for data center growth is exposed to any slowdown in that construction cycle, and engineering-led operations depend on retaining the specialists who do the work. GCG’s CEO emphasized its people and culture in announcing the sale; keeping that capability intact inside a 26,306-employee group will determine whether Rexel gets what it is paying for.

Background

Rexel is a publicly held distributor of electrical and energy-management products serving residential, non-residential and industrial customers for construction, renovation, production and maintenance. It operates 1,876 branches in 17 countries with 26,306 employees and reported €19.4 billion in 2025 sales.

GCG began as Genuine Parts Company’s Electrical Specialties Group before Audax Private Equity acquired it in a carve-out. Under Audax, it expanded through organic growth and a series of acquisitions into a specialty wire, cable and connectivity distributor with 16 locations in North America and Europe, more than 950 employees and expected 2026 revenue above $1.1 billion.
