AstraZeneca (AZN) Stock Analysis & Winston Score
AstraZeneca is a global pharmaceutical company that discovers, makes, and sells prescription medicines. Its main products include cancer drugs like Tagrisso and Enhertu, heart and kidney medicines like Farxiga, and respiratory treatments like Symbicort. It sells primarily to hospitals, clinics, and pharmacies, with patients and healthcare systems as the end users. The company earns money by selling branded prescription drugs, which carry high prices protected by patents. AstraZeneca operates in over 100 countries, with major revenue coming from the US, Europe, and a fast-growing China business. Its competitive edge comes from a strong oncology pipeline and deep research partnerships, but patent expirations on key drugs remain a persistent risk — when patents expire, cheaper generic versions can quickly erode sales. The company's ability to keep launching new cancer and rare-disease treatments from its pipeline will be the main factor driving future growth.
