Johnson Matthey Plc operates as a specialty chemicals and sustainable technologies company with a primary focus on catalysis and precious metals. The company's business model is centered around three core segments: Clean Air, PGM Services, and Hydrogen Technologies. The Clean Air segment is a major revenue contributor, providing emission control catalysts for light- and heavy-duty vehicles to reduce harmful exhaust emissions. The PGM Services segment is the world's largest secondary refiner of platinum group metals, offering refining, recycling, and trading services, as well as manufacturing value-added PGM chemicals and industrial products. The Hydrogen Technologies segment develops components for fuel cells and electrolysers, including catalyst-coated membranes. Historically diversified, Johnson Matthey has recently streamlined its portfolio to focus on the energy transition and its core competencies in precious metals and catalysis. This included the sale of its Health division (Veranova) in 2022, its Medical Device Components and Battery Systems businesses in 2024, and the agreement to sell its Catalyst Technologies division to Honeywell in 2025. Geographically, the company operates globally with a significant footprint in the UK, Europe, North America, and Asia. Its competitive position is underpinned by over 200 years of expertise in metal chemistry and a dominant market share in autocatalysts and PGM refining.
