Gilead Sciences transformed the treatment of HIV and hepatitis C, producing antiretroviral regimens now used by tens of millions of people worldwide and a hepatitis C cure that changed the standard of care globally. Founded in 1987 and headquartered in Foster City, California, Gilead is listed on the Nasdaq under the ticker GILD and operates across more than 35 countries, with manufacturing, clinical research, and commercial operations spanning North America, Europe, and Asia.
The company's HIV portfolio includes single-tablet regimens that brought once-complex treatment schedules down to a daily pill, including the widely prescribed Biktarvy and Descovy. Gilead's HIV medicines anchor national treatment guidelines in numerous countries and the company also markets Truvada and Descovy for pre-exposure prophylaxis (PrEP). In viral hepatology, its Sovaldi and Harvoni regimens achieved cure rates above 90 per cent for hepatitis C, redefining what patients and clinicians could expect from antiviral therapy.
Gilead has built a substantial oncology division, accelerated by its acquisition of Kite Pharma in 2017, which brought cell therapy capabilities including the CAR-T treatment Yescarta for certain blood cancers. The subsequent acquisition of Immunomedics added Trodelvy, an antibody-drug conjugate indicated for specific breast and bladder cancers. The company continues to invest in inflammation, lung disease, and emerging infectious diseases, reflecting a broader ambition beyond its original antiviral roots.
Gilead's global access programmes and tiered-pricing agreements with generic manufacturers have extended its HIV medicines to lower-income countries, making it a significant participant in public health efforts coordinated with organisations such as PEPFAR and the Global Fund. The company reports annual revenues in excess of twenty billion US dollars and employs approximately seventeen thousand people worldwide.
