Summary

  • Rexel values GCG at about $1.4 billion and says that equals less than eight times 2026 estimated EBITDAaL including anticipated run-rate synergies. At exactly eight times, the denominator would be $175 million; the company does not disclose standalone GCG EBITDAaL or the amount and timing of the synergies that take the multiple below that line.
  • The disclosed operating figures—more than $1.1 billion of 2026 estimated sales and an EBITA margin of about 11%—do not fill the gap. EBITA is not EBITDAaL, and the transaction materials do not provide the depreciation, amortisation, lease or adjustment bridge needed to convert one into the other.
  • The useful post-signing ledger joins operating delivery to financing: standalone cash earnings, synergy owners and costs, up to €500 million of contemplated equity, roughly €800 million of cash and debt, integration cash, leverage and realised ROCE. Until those pieces reconcile, “below 8x” is a management execution target rather than a completed purchase multiple.

The most consequential word in Rexel’s valuation of GCG is not “eight.” It is “including.”

Rexel says the proposed $1.4 billion enterprise value is less than eight times GCG’s 2026 estimated EBITDAaL including anticipated run-rate synergies. That last phrase moves part of the denominator out of the acquired company’s current economics and into the buyer’s future execution. Scale benefits, logistics optimisation, insourcing and selected efficiencies may arrive. At signing, they remain a plan.

This does not make the acquisition unattractive. GCG gives Rexel a larger position in specialist wire, cable, connectivity and power applications where engineering and assembly can matter more than simple product resale. The target is expected to exceed $1.1 billion of revenue in 2026, with an EBITA margin near 11%. Rexel says more than three quarters of sales include value-added products or services and more than 60% are exposed to markets it classifies as high growth.

It does, however, make the headline multiple impossible to reproduce from the public numbers. A valuation claim that begins after synergies needs a bridge before it can become evidence.

The disclosed arithmetic stops before the denominator

At exactly eight times, $1.4 billion implies $175 million of EBITDAaL. A multiple below eight therefore requires a denominator above $175 million, subject to the imprecision in the stated enterprise value. Rexel does not say how much of that denominator belongs to GCG before integration and how much consists of anticipated synergies.

The presentation supplies a nearby number, but not a substitute. More than $1.1 billion of expected sales at an EBITA margin of about 11% points directionally to more than roughly $121 million of EBITA. One cannot subtract that figure from $175 million and label the remainder “synergies.” EBITA and EBITDAaL treat depreciation, amortisation and leases differently; “more than,” “about” and estimated figures also do not create an exact base. Rexel’s own presentation identifies EBITDAaL and EBITA as alternative performance measures rather than standardised IFRS measures.

The absent schedule is straightforward. Start with GCG’s standalone EBITDAaL under Rexel’s definition. List every adjustment from EBITA. Then add each gross synergy by source and date, subtract the recurring dis-synergies and the cash cost to achieve them, and state when the run rate is expected to be visible in reported accounts. Without that schedule, the market knows the desired answer but not the route.

That distinction matters because synergies are not a free asset transferred by the seller. They are created, if at all, after Rexel has paid the seller. Procurement savings may require supplier renegotiation. Logistics savings may require site, inventory or transport changes. Insourcing may require capacity and working capital. Commercial cross-selling may consume sales time and can be constrained by customer or supplier relationships. Each source has an owner, a cost, a start date and a risk of leakage.

GCG is more than a cable catalogue

The strategic case is stronger when it is described concretely. GCG’s public offer includes engineering, custom assembly, product modification, kitting, testing and rapid fulfilment. These functions can place a distributor earlier in a customer’s design and procurement process. They can also make the relationship harder to replace than a catalogue order, because the supplier is performing configuration, quality control and delivery work that the customer would otherwise organise.

Rexel’s presentation shows the target serving a diversified set of infrastructure markets. Data centres account for 21% of the stated 2026 estimated mix, power and utilities 18%, industrial infrastructure 12%, defence 11%, telecom 10%, water and agriculture 10%, transport 4% and other activities 14%.

Those percentages resist one easy exaggeration. GCG is not simply an AI data-centre purchase. Data centres are important, but most of the stated revenue mix sits elsewhere. The transaction is a wager on specialised infrastructure distribution across power, communications and engineered applications. The investment case should therefore be tested through order quality, customer retention, working-capital needs, service-line margins and cash conversion—not through a general claim that artificial intelligence will increase electricity demand.

The presentation gives customer examples of installation time or equipment power-up improving through engineered assemblies. Such examples help explain the service model. They are not audited measures for GCG as a whole and should not be compounded into the acquisition forecast.

Financing changes which risk shareholders carry

Rexel proposes to fund roughly €800 million from cash on hand and debt, with debt described as fully underwritten. It also intends to raise up to €500 million in equity through an accelerated bookbuilding, subject to market conditions. As of the research freeze, Rexel’s regulated-information page did not show a later announcement that the equity issue had been launched, priced or completed.

That conditionality is central. Equity can protect the credit rating and reduce the debt burden, but it does not remove acquisition risk; it reallocates part of it into dilution. The result depends on the amount actually raised, issue price, discount, number of new shares, fees, debt displaced and interest avoided. A year-one EPS-accretion target cannot be assessed from the purchase price alone.

The group entered this transaction after an active acquisition and financing period. At 30 June 2026, Rexel reported €3.3219 billion of net financial debt, up from €2.6314 billion at the end of 2025. It held €1.0338 billion of cash and cash equivalents and reported €1.7847 billion of liquidity. Its leverage ratio under the revolving-credit-facility definition was 2.39 times, below the 3.50-times covenant.

These figures do not signal an announced covenant problem. They show why the funding mix matters. During the first half, acquisitions of subsidiaries used €392.4 million of cash net of cash acquired. Free cash flow after interest and tax was €72.8 million, while financing included a €400 million convertible bond and €125 million of Schuldschein. The GCG deal is large enough that the route back to Rexel’s stated net-debt-to-EBITDAaL level of about two times from 2027 cannot be inferred from a single pro-forma ratio.

The bridge should separate at least five effects: equity proceeds, new borrowing, acquired EBITDAaL, realised net synergies and cash conversion after integration spending. If the ratio falls because more equity is issued, that is a different economic path from a decline produced by cash earnings. Both may protect the balance sheet; they do not create the same per-share return.

Accretion is not yet the return test

Rexel targets EPS accretion in year one, more than 20 basis points of group EBITA-margin accretion and ROCE above WACC in year three. The sequence sounds disciplined, but the three tests answer different questions.

EPS can rise because of operating earnings, financing choices, tax, purchase-accounting adjustments or the share count. Margin accretion shows that the acquired mix is more profitable on an EBITA basis than the group average, but says nothing by itself about the price paid for that margin. ROCE above WACC is the closest of the stated measures to an economic-value test because it compares an operating return with the capital required to earn it.

Even that claim needs definitions. The public material does not state the WACC used, the invested-capital base, the purchase-price allocation, the treatment of goodwill and acquisition intangibles, or whether the return numerator includes all integration costs. A reproducible year-three result should show the acquired earnings, net synergies, tax, working capital, capex, cumulative implementation cash and capital employed.

The time boundary also matters. “Run-rate” savings can be present in a plan before they are present for a full year in cash. A site consolidation announced in the second half may be annualised into a run rate while severance, duplicate rent, inventory movement and system migration remain in the cash-flow statement. The market needs both the exit rate and the cash history.
