BIO.B

Bio-Rad Laboratories, Inc. Class B shares represent the same underlying company as Class A shares but with different voting rights. Bio-Rad is a leading provider of life science research and clinical diagnostic products. The company operates with a dual-class share structure where Class A shares (BIO) carry one vote per share while Class B shares (BIO.B) carry non-voting rights or limited voting rights. Both share classes receive identical dividend payments and have the same economic interests in company performance. The founding Schwartz family maintains significant control through ownership of voting shares, enabling long-term strategic focus. Bio-Rad's business spans life science research products (instruments, consumables, software for protein analysis, genomics, cell biology) and clinical diagnostics (quality controls, blood typing, autoimmune testing). The company serves researchers, hospitals, clinical laboratories, and biopharmaceutical companies globally. Bio-Rad benefits from mission-critical products, recurring revenues, and strong market positions. Class B shares typically trade at similar prices to Class A shares since control is concentrated with insiders. Both share classes provide exposure to Bio-Rad's diversified life science and diagnostics business.
