# Legrand's guidance raise is a formal notice: the building business is being sold to fund the AI bet

> The French group raised its 2030 targets and, in the same breath, put €0.5 billion to €1.0 billion of its traditional building sales up for sale, completing its conversion into a toll on the AI data-center buildout.

[Legrand](https://theinference.org/markets/companies/legrand)'s guidance raise on Monday was more than a numbers bump: it is the moment a century-old wiring-and-switches maker formally announced it is selling its old self. Alongside targets lifted to 6-8% annual organic growth for 2027-2030 (from 3-5%) and a 21-22% adjusted operating margin (from around 20%), the group [pencilled in divestments worth €0.5 billion to €1.0 billion of sales](https://www.marketscreener.com/news/legrand-2026-capital-markets-day-ce785adcd188f021), to be funded by acquisitions adding roughly five percentage points of sales a year [2]. Coquart named the mechanism himself: "acquisitions, which will mainly be in the energy and digital transition sectors; the divestment, which will take place in the core business; and, quite simply, the different rates of organic growth" [1]. That the divestments land in the building business is the plain reading of his own words, not a figure the release states.

## The old business is set to shrink to 30% of sales

The legacy side is where the money gets left behind. Legrand puts European construction growth at just 1-3%, and sees the US residential and commercial outlook slightly less positive [1]. The historical building business, 46% of sales on the H1 2026 split, is set to shrink; arithmetically, if energy and digital transition reaches the around 70% of revenue Coquart targets for 2030, buildings fall to roughly 30% [1][2]. Energy and digital transition, which includes data-center infrastructure, stands at 53% of revenue in 2025 [1].

## The whole case rests on one number: 180 gigawatts

What Legrand is really doing is converting itself into a toll on the AI buildout. Its data center operations will exceed €3 billion of sales in 2026, spanning critical power (35% of that business), physical compute infrastructure, monitoring and control, cooling and lifecycle services, and management defended the model at Tuesday's Capital Markets Day in Singapore, held alongside Data Centre World Asia [2]. The demand receipt Coquart offers is stark: [80 gigawatts of installed data-center IT capacity today, rising to 180 by 2030](https://srnnews.com/legrand-raises-mid-term-targets-on-data-centre-growth/), with clients bolstering AI investment plans even as some AI leaders urge developers to slow down [1]. That single figure is the whole investment case for the supply chain, priced into a stock that had risen about 6% as of Tuesday's close (a five-day move per MarketScreener) [2].

## No buyer is named for the business being sold

The open question the documents do not answer is who buys the €0.5-1.0 billion of divested building assets, and at what price; the release names no counterparties [2]. The risk sits with buyers paying a buildout multiple for an industrial: nothing in either source addresses construction schedules or [grid connections](https://theinference.org/article/ai-s-750-billion-buildout-now-waits-on-a-virginia-county-board) behind the 80-to-180-gigawatt curve [1], so if it slips, the legacy business is too small, and already partly for sale, to catch the earnings.

## Takeaway

Legrand's raised 2030 targets come with a plan to sell up to €1.0 billion of building sales: the group is funding its conversion into a data-center supplier out of its own legacy business.
