Legrand Acquires Keydak and TES for Data Center Growth

Legrand, a global specialist in electrical and digital infrastructure, is significantly expanding its footprint in the critical data center sector through two strategic acquisitions. The French industrial giant has secured deals for Keydak in China and TES in the United Kingdom, reinforcing its capabilities in both compute infrastructure and essential power distribution systems.

The acquisition of Keydak, based in Guangzhou, marks a substantial move into the Chinese market. This company is a prominent manufacturer of data center racks, employing over 330 professionals and generating annual revenues in excess of €60 million. This addition directly enhances Legrand's offerings in the physical infrastructure that houses computing hardware, a vital component of the rapidly growing data center ecosystem.

Simultaneously, Legrand is integrating TES, a Northern Ireland-based firm specializing in power distribution systems. With a significant portion of its nearly €85 million in annual revenue stemming from data center operations, TES brings deep expertise in ensuring the reliable and continuous power supply essential for these facilities. The company's workforce of 280 employees further bolsters Legrand's operational capacity in Europe.

Collectively, these two transactions are projected to inject approximately €145 million into Legrand's annual revenue stream, specifically within its data center segment. This strategic expansion aligns with Legrand's stated 2030 growth strategy, which prioritizes the development and consolidation of its position in electrical and digital infrastructure tailored for data centers. These acquisitions represent the fourth and fifth such targeted deals for Legrand in 2026, underscoring the company's focused commitment to this high-growth market.

The data center industry continues its upward trajectory, driven by escalating demand for cloud computing, artificial intelligence, and big data analytics. In 2025, data centers already constituted 26% of Legrand's total revenue, highlighting the sector's importance to the company's financial performance. These acquisitions are not merely about increasing scale; they are about deepening technological capabilities and market penetration in a sector that requires specialized solutions for power, cooling, and connectivity.

Benoit Coquart, CEO of Legrand, emphasized that these moves are designed to fortify the company's standing in the data center market. By acquiring expertise in both the physical housing of servers (compute infrastructure) and the robust power systems required to run them, Legrand is positioning itself as a comprehensive solutions provider. This integrated approach is crucial as data centers become more complex and energy-intensive, demanding sophisticated infrastructure management.

The global data center market is experiencing robust expansion, with significant investment flowing into new builds and upgrades. Companies like Legrand are strategically acquiring specialized players to capture market share and offer end-to-end solutions. The successful integration of Keydak and TES will enable Legrand to better serve hyperscale cloud providers, colocation facilities, and enterprise data centers seeking reliable and efficient infrastructure partners.
