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.

The Short Version

Most people have never heard of Wesco, but the giant computer warehouses behind the internet and artificial intelligence need what it sells: electrical and communications gear.

Those warehouses brought Wesco $1.5 billion in sales in three months, about 45% more than a year earlier. They made up less than a quarter of its sales but about 60% of its growth.

A very large operator of these warehouses also signed a multi-year deal with the Wesco unit that serves power companies. The building boom is now reaching the company’s electric grid business.

Wesco International (NYSE: WCC), a Pittsburgh-based distributor of electrical, communications and utility products, reported record second-quarter net sales of $6.67 billion on July 30, 2026, up 13.0% from a year earlier. Data center sales reached $1.5 billion, up about 45%, and total company backlog hit a record, up about 60%.

The company also raised its full-year 2026 outlook and disclosed a significant multi-year Grid Services award from a hyperscale data center customer, meaning one of the very large operators of data center capacity.

Executive Summary

Wesco’s second quarter offers a useful test of how far data center spending travels beyond chips and servers. Distributors buy from manufacturers and supply the contractors, utilities and operators doing the building, so their results show demand for the less visible equipment that makes a facility work. At Wesco, that demand is now large: data centers accounted for more than a fifth of quarterly sales and, on rounded figures, about 60% of the year-over-year increase.

The most telling disclosure may be qualitative. CEO John Engel said the hyperscale award landed in the Utility and Broadband Solutions (UBS) segment and called it an important step in diversifying that segment’s customer base. That extends Wesco’s data center relationships from products used inside the facility toward power solutions.

The profit picture was strong, with adjusted EBITDA (earnings before interest, taxes, depreciation and amortization, excluding certain items) up 23.6% to $487.2 million. Second-quarter free cash flow, however, fell 62.7% to $32.3 million as receivables and supplier prepayments absorbed cash, a reminder that rapid growth has to be financed.

A Fifth of Sales, Most of the Growth

Wesco’s net sales rose by $765.5 million, from $5.90 billion to $6.67 billion. Its data center sales of $1.5 billion, up about 45%, imply a year-earlier figure of roughly $1.03 billion, or an increase of about $465 million. Working from those rounded numbers, data centers represented about 22% of quarterly sales but about 60% of the dollar growth.

The same arithmetic implies that everything else grew about 6%. That is consistent with Engel’s statement that demand remained strong across the rest of the portfolio, but it also shows how much of the headline 13% depends on one end market. Wesco’s four consecutive quarters of double-digit sales growth were, in Engel’s words, “fueled by data centers.” The calculation uses reported sales rather than organic sales, which exclude currency and workday effects, though the two growth rates were close at 13.0% and 12.6%.

For the industry, this is a concrete measure of data center demand reaching the distribution layer. For Wesco investors, it is also a concentration question: the stronger this one market becomes, the more the company’s growth rate depends on its continued spending.

The Grid Award Is the Quarter’s Clearest Signal

Wesco has described its data center offering in terms of white space, the rooms that hold servers and network equipment, and gray space, the support areas for electrical and mechanical systems. Engel said the new award expands that offering “to include power solutions.” The fact that it sits in UBS, rather than only in the segments more readily associated with data center fit-out, is what makes it notable. It places a hyperscale customer alongside the utility and broadband business, and Engel framed the win as “an important step in diversifying our UBS customer base.”

The mechanism matters more than the label. A distributor’s data center exposure no longer has to end at the building’s interior if a large operator will also contract for grid-related services. That widens Wesco’s potential share of each project and gives its utility-facing business a new type of customer. It also matters to rival distributors and electrical suppliers, because a customer buying across power, communications and security categories from one provider could reduce the number of separate supply relationships it needs.

The limits are equally clear. This is one award, at one company, with no public value or duration attached in Engel’s remarks, and it does not establish an industry-wide shift. UBS was also the one segment where Wesco reported lower gross margin, although the company did not connect that decline to the award. What can be said is narrower and well supported: at Wesco, hyperscale demand has now reached grid work, and management sees that as a strategic milestone.

Backlog Growing Faster Than Sales Changes the Question

Backlog, the value of orders not yet recognized as revenue, rose about 60% while sales rose 13%. Engel said the growth was “fueled by multi-year customer commitments.” That points to visibility extending further out, which is valuable to a distributor that has traditionally been judged quarter to quarter.

It also means the figure should not be read as near-term revenue. A multi-year commitment may convert over several periods, and a large project can move with construction schedules, equipment deliveries and power availability. The 60% figure is also company-wide, so it cannot by itself be read as a measure of data center demand, even though data centers are the most visible growth driver in the quarter.

Growth Is Absorbing Cash, at Least This Quarter

Operating cash flow fell to $53.7 million from $107.8 million. Wesco attributed the decline to a $182.8 million impact from trade receivables, reflecting sales growth and timing of customer payments, and a $155.3 million impact from other assets, primarily supplier prepayments. A $129.9 million offset came from other liabilities, driven by higher deferred revenue, which is money received before revenue is recognized.

Prepayments on one side and deferred revenue on the other suggest cash moving earlier through the chain, in both directions. That pattern would fit long-lead project work, though Wesco did not tie either item specifically to data centers. The single quarter should not be overread: first-half free cash flow more than doubled to $245.7 million from $95.9 million, helped by payables and deferred revenue.

Profitability moved the other way. Adjusted gross margin rose 70 basis points (0.7 percentage points) to 21.8%, and adjusted EBITDA margin rose 60 basis points to 7.3%. Those gains came even as adjusted selling, general and administrative costs rose to 15.0% of sales from 14.6%, driven largely by commissions, incentives, salaries and benefits. Whether margin and cash conversion improve together as backlog turns into revenue is a key test for the second half.

Background

Wesco International provides business-to-business distribution, logistics services and supply chain solutions through three segments: Electrical and Electronic Solutions (EES), Communications and Security Solutions (CSS), and Utility and Broadband Solutions (UBS). It serves commercial and industrial businesses, technology companies, telecommunications providers and utilities, with approximately $24 billion in 2025 sales, about 21,000 employees and more than 700 sites in roughly 50 countries.

Distributors sit between equipment manufacturers and the customers installing that equipment. They can hold inventory, coordinate logistics and bundle products and services across multiple sites. Wesco now describes itself as a leading infrastructure solutions provider, and its “One Wesco” cross-selling strategy aims to sell across its segments, an approach management credited as contributing to the record backlog.
