Legrand is pursuing its active bolt-on acquisition strategy with the announcement of two new transactions in datacenters:

“These two new transactions strengthen our positions in the datacenter market, both in compute infrastructure (around the chip) and in critical power. With these announcements, a total of four acquisitions have been announced this year, all in datacenters, which accounted for 26% of our revenue at the end of 2025. Together, these acquisitions represent around €285 million in additional annual revenue and reflect the consistent execution of our strategic roadmap towards 2030.”
