Legrand's Data Center Engine Is Accelerating Into a Tape That Has Left
A 19% organic quarter, a fourth upgrade to data center guidance, and a flat margin guide — all delivered into a market that has spent ninety days selling AI infrastructure

A 19% quarter in a market that sold the theme
Legrand's nine-month release is, on its face, the best operating print in years. Sales reached EUR 8.3bn, up 22.1% excluding currency effects, of which 12.7% was organic. The adjusted operating margin held at 20.8%, free cash flow rose 15.9% to EUR 1bn (12.1% of sales), and net profit attributable to the group came in at EUR 1.1bn, up 19.6%. Management raised the 2026 organic growth target to 11-13% from 8-10%.
The engine is the same one it has been for three years. Data centers grew close to 40% organically over nine months, including close to 50% in the third quarter — the fastest rate of the cycle — and the full-year target was lifted again, to 35-40%. That is the fourth consecutive upgrade to data center growth guidance.
And here is the tension. Over the last ninety days the market has been actively de-rating precisely that exposure. The AI data centers theme basket is down roughly 31% on both the 30- and 90-day windows, with 55 decliners against 11 advancers over the past month; high bandwidth memory, co-packaged optics and data center interconnects are each down 35-40% over the same span. Legrand is printing its fastest data center growth of the cycle into a tape that has decided the cycle is peaking. In July, Coquart had already waved off the bubble question — “I've not heard much about a bubble as far as the AI was concerned. I heard a lot about bubble concerning potential valuations.” — Benoît Coquart · 2026-07-29 — but the tape has since taken the valuations side of that argument.
If you look at the midpoint of our guidance, it implies a Q4 at plus 10%, which is very consistent with the H1 we did at plus 10%. So our scenario is that Q3 saw a sort of surge in sales, but which is not sustainable, and we don't expect to do again a plus 19% like-for-like evolution every single quarter. So the sort of sustainable recurring kind of growth we are experiencing is closer to 10%.
That is Benoît Coquart answering Delphine Brault, and it is the most important sentence on the call. The full-year organic raise was, arithmetically, almost entirely a third-quarter event. H1 grew 10%. The guide implies Q4 at 10%. The run-rate the company actually believes in is 10%. What changed in the guidance was one quarter of surge — and management said so out loud rather than letting the market extrapolate.
Three years of under-promising, and the market still flinches
There is a pattern worth naming. In February Legrand guided data centers to +10-20% for 2026; in July it moved to 25-30%; it has now delivered ~40% and lifted to 35-40%. Every year since 2024 management has started below the outcome and been dragged up by order flow. So when Coquart says the demand picture is intact, the burden of proof runs the other way: “Are we seeing any sign of the demand weakening? The answer is clearly no. We are not.” — Benoît Coquart, Chief Executive Officer (CEO) · 2026-11-05
The 2027-2030 anchor is the Capital Markets Day arithmetic: 300GW of announced capacity, deliberately discounted. “We have discounted that down to 100. So we took only 1/3 of the announced capacity in our plan. And this 100 gigawatt capacity is enough for the market to grow 15% to 20% per year.” — Benoît Coquart, Chief Executive Officer (CEO) · 2026-11-05 He adds that the five big hyperscalers opened the year at roughly $500bn of CapEx and now look closer to $800bn, with further increases flagged for 2027 — and that the U.S. midterms came and went with no change in customer conversations, a direct rebuttal of the tape's implied thesis.
The operating leverage question, for the third straight call
In July, William Mackie put it plainly: organic guidance up sharply, margin guidance flat — how should we think about the lack of operational gearing? The answer then was candid. “we have also all the inefficiencies that comes with the strong growth we are experiencing in data center, which is difficult to quantify, which to be very candid, which we haven't quantified.” — Benoît Coquart · 2026-07-29
In October, Daniela Costa asked the same thing in different clothes. The answer is now a clean structural explanation rather than an apology: “the data center business has a level of gross margin which is below group's average and a level of SG&A, which is below group's average and an EBIT margin, which is more or less the group's average.” — Benoît Coquart, Chief Executive Officer (CEO) · 2026-11-05 North American gross margin fell 190bps in Q3, half mix and half acquisitions. Europe — the sore point in July at an 18% segment margin — recovered, and management pointedly refused to claim vindication: “Our European margin was not a concern in H1, and it's not a relief in Q3. It is exactly where we expect it to be.” — Benoît Coquart, Chief Executive Officer (CEO) · 2026-11-05
The strategic read is that Legrand has chosen growth over margin at the group level, and the 2030 framework codifies it: 6-8% organic CAGR plus ~5% annual scope effect, with a 21-22% adjusted operating margin on average, after acquisitions and including restructuring. That is a half-point to a point above where the group has historically run — a compound target, not a step change.
What management stopped talking about
Worth flagging: the 800VDC anxiety is gone. In the first quarter, volt DC architecture was a top-five keyword on this call; in February Coquart spent paragraphs on the side-car and the 80/20 split — “it will have a neutral to negative impact on about 20% of Legrand sales and a neutral to positive impact on 80% of Legrand sales” — Benoît Coquart, CEO · 2026-02-12 — and in July analysts queued up on OCP and solid-state breakers. On this call, Lucas Ferhani got one question about "new architectures" and the answer was essentially that the CMD is six weeks old, everything is on plan, nothing has changed.
What replaced it in the keyword set is operational: power usage effectiveness, capacity increase and CapEx investment. That is a company that has moved from defending its architecture position to defending its ability to ship. The rank-one keyword this quarter is value creation, with strategic roadmap in third — a framing shift from "data center growth story" to "compounder with a 2030 framework."
Pricing creep and the M&A treadmill
The selling price line has been revised upward every quarter of 2026: +1-2% in February, +2-3% in May, around +3% in July, and now +3.1% realised over nine months with 3.2-3.5% guided for the full year, against purchase price inflation of a little over 3%. That is a company passing cost through in value but explicitly not in margin — the recurring phrase is compensating in value, not necessarily in margin.
M&A: seven deals year to date, roughly EUR 450m of annual sales, at about 11x 2026 EBIT pre-synergies. Coquart said larger deals are welcome and "almost the bigger, the better" — a notable change of register for a serial tuck-in buyer. The divestment programme, EUR 0.5-1bn of sales spread across the plan to 2030, had no update.
The bet
Two things can be true at once. Legrand can compound data center revenue at 40% while the market decides the whole complex is over-earning. The company's case — hyperscaler CapEx rising, only a third of announced gigawatts in the plan, power constraints and efficiency regulation as net positives for a vendor of PUE-reducing gear — is coherent, and it has been right for three years running. The market's case — the basket is down 30% in ninety days — is also coherent, and it is the marginal price-setter right now.
What settles it is not another 19% quarter. It is the 2027 guidance in February, and whether the "sustainable 10%" turns out to be a floor or a landing strip.
