Roche Holding AG (ROG.SW) Stock Analysis & Winston Score

Roche is a Swiss healthcare company that makes medicines and diagnostic tests. Its pharmaceutical division sells treatments for cancer, multiple sclerosis, and eye diseases — drugs like Herceptin, Avastin, and Ocrevus are among its best-known products. Its diagnostics division makes the lab equipment and tests that hospitals use to detect diseases, making Roche one of the few companies that both treats and diagnoses illness at scale. Roche earns money by selling prescription drugs to hospitals and healthcare systems, and by selling diagnostic instruments and consumables to labs worldwide. It operates globally, with strong revenue from the United States, Europe, and Japan, and generates roughly 50 billion Swiss francs in annual sales. Its deep pipeline of cancer drugs and its integrated diagnostics business create a durable competitive position, but the expiration of patents on older blockbuster drugs and growing competition from biosimilars remain the central financial risk the company must manage.
