The largest pharmaceutical enterprises in the world, such as Johnson & Johnson, Pfizer, Roche, and Eli Lilly, are publicly traded corporations owned collectively by millions of institutional investors, mutual funds, pension funds, and retail shareholders across global stock exchanges. Unlike privately held businesses, no single individual or family owns a controlling stake in these major multinational drug manufacturers. Instead, governance and strategic oversight are managed by elected boards of directors and professional executive teams acting on behalf of global shareholders.
