Elliott Management, the prominent activist investment firm, has built a substantial stake in Bio-Rad Laboratories, a supplier of life-science tools and equipment.

The investment move comes as Elliott continues to expand its presence in the laboratory equipment and life sciences sector. The firm also holds a position in Sartorius, a German laboratory equipment supplier, creating potential portfolio synergies within the sector.

Bio-Rad Laboratories, which operates in the life sciences research and clinical diagnostics markets, is also an investor in Sartorius, adding another layer of interconnection between Elliott's holdings in the laboratory equipment space.

The size and timeline of Elliott's stake in Bio-Rad were not immediately disclosed. Elliott Management, founded by Paul Singer, is known for taking activist positions in companies and pushing for operational improvements or strategic changes to enhance shareholder value.

Bio-Rad, founded in 1952 and based in Hercules, California, manufactures and distributes life science research and clinical diagnostic products used in universities, medical schools, government agencies, hospitals, and biotechnology companies worldwide.
