最新报道:Activist investor Standard Investments has reduced its stake in Johnson Matthey by half, cutting its holding from 10% to 5%, according to a regulatory filing. The move comes after the London-based firm pressured the specialty chemicals company to spin off its battery materials business last year. Johnson Matthey, which supplies catalysts for vehicles and pharmaceuticals, had previously announced plans to exit the battery sector to focus on more profitable segments. Standard Investments, known for pushing strategic changes at underperforming companies, did not disclose reasons for the stake sale. Shares of Johnson Matthey dipped 2% following the news.
