In the latest developments, Mersen achieved record sales of €1.244 billion in 2024 with organic growth of 2.6%, marking a new revenue high despite a challenging market environment affected by a slowdown in the electric vehicle and silicon carbide semiconductor sectors. The company realized significant expansion through three acquisitions in the United States in 2024, including the July acquisition of GMI Group, an expert in graphite and carbon composites, enhancing its production capacity and market reach in advanced materials. Capex reached over €204 million in 2024, directed towards growth initiatives, modernization, and sustainability. Mersen also implemented operational improvements such as inventory reduction and working capital optimization, while postponing some growth targets to 2029 in response to temporary demand softness in certain segments. The company continues to innovate within its product lines and pursue strategic growth, reinforcing its leadership in electrical power safety and materials solutions globally.
