Johnson Matthey Plc began its operations in 1817 when Percival Norton Johnson opened a gold assayer in London. In addition, Mr. Johnson tested the purity of precious metals as part of his business. In 1891, the company was officially incorporated and acquired the name Johnson, Matthey & Co. Ltd.
The company went public in 1981 and changed the name yet again to Johnson Matthey Plc. Since then, the company’s shares trade on the London Stock Exchange under the symbol JMAT. The company is also part of the FTSE 100 component. Although Johnson Matthey began as an assayer of gold, the company expanded its scope as it grew. Today, the company produces, markets, and distributes specialty chemicals across the three continents of Europe, Asia, and North America. Some of the products JMAT produces go into the automotive industry as catalysts for the combustion engine. Johnson Matthey has its headquarters in London, the United Kingdom.
