Over the period, France (contributed revenue up +6.9% at constant scope) confirmed the solidity of its industrial and local authorities markets, underpinned by the dynamic growth of the circular economy and the dynamic performance of services activities.

Internationally (revenue up 29.5% at constant scope and exchange rates), the Group also benefited from a good performance of its activities across all of its regions, while activity also saw significant "spot" operations in Q1 (decontamination and environmental emergency) which increased growth in South Africa and Peru.

Growth outlook confirmed

This good start to the year underpins Séché Environnement's growth prospects for the current year.

Positioned on the Circular Economy and Decarbonization markets, and a player in industrial relocation as part of an ecological transition approach, the Group is responding to the challenges faced by the regions by supplying low-carbon regenerated resources, raw materials and energy, while the geopolitical context increases the cost of fossil resources along with the attractiveness of the solutions proposed by the Group.

Séché Environnement's business lines, which are essential to protecting the environment and responding to regulatory requirements in order to facilitate the ecological transition, therefore show strong resilience in the event of an unfavorable downturn in the economic cycle, particularly in France.

Séché Environnement reaffirms its confidence in achieving its business growth targets in 2022, with organic growth in line with the trends observed in the second half of 2021.
