Over the past year, Legrand reported a 9.6% increase in revenue, reaching 9.48 billion euros, slightly above the consensus forecast of 9.46 billion euros. Data centers accounted for 26% of the group's revenue. "Organic growth came in at 7.7% for the full year, including 6.2% in the fourth quarter alone (consensus at 4%), after 6.7% in the third quarter. Data centers continued to play a key role despite a tougher comparison base," notes Oddo BHF, which maintains a neutral stance on the stock.

Adjusted operating profit rose by 10.5% to 1.96 billion euros, in line with expectations.

For 2026, the group is targeting sales growth between 10% and 15% and an adjusted operating margin after acquisitions of 20.5% to 21.0% of revenue.

Legrand will propose a dividend payment of 2.38 euros per share for 2025.

"Legrand is showing clear optimism, emphasizing that its business model will benefit from the increased use of direct current electrical distribution in data centers," notes Jefferies, which has a buy rating on the stock that has posted the third largest gain on the CAC 40 (+21.57%) since January 1.
