About MERSEN

Mersen is a French industrial group listed on Euronext Paris under ticker/ISIN FR0000039620 (MRN), focused on electrical power solutions and advanced materials. The company describes itself as a global expert serving high-tech industries, with a business model centered on energy transition, power electronics and demanding industrial processes. Headquartered in France, Mersen has a broad international footprint, operating more than 50 industrial sites and 21 R&D centers across 33 countries. In 2024, the Group reported record sales of €1.244 billion. Mersen’s roots go back more than 130 years, giving the company a long industrial heritage and a track record of adapting to successive technological waves. Over time, it has built strong expertise in carbon-based materials, specialty graphite and electrical protection equipment, while also expanding through innovation and targeted acquisitions. Management highlights that the Group has gained a new dimension in recent years thanks to the combination of technical know-how, global presence and leading positions in several industrial niches. The company is organized around two main business segments. Electrical Power Solutions includes fuses, fuse-holders, fusegear, surge protection devices, signal transmission systems, carbon brushes and brush-holders, as well as solutions for power conversion and electrical distribution. Advanced Materials covers high-purity graphite and composite materials, silicon carbide (SiC) solutions and technical materials used in semiconductors, solar power, aerospace, space, chemicals and process industries. Mersen therefore addresses markets where reliability, performance and resistance to harsh environments are critical. From a competitive standpoint, Mersen holds a recognized position in several high-value niche markets and is closely tied to long-term structural themes such as electrification, renewable energy, electric mobility, power grids and power semiconductors. The Group says that a majority of its sales are linked to the energy transition, underscoring its strategic exposure to secular growth drivers. In 2025, it also reported solid momentum in electrical distribution, wind and rail markets, even as solar demand in China and the SiC semiconductor market remained weak. This mix of specialized expertise, global reach and exposure to long-duration growth trends makes Mersen a notable industrial company with strong international relevance.
