Understand Gilead Sciences, Inc.: how it makes money

Gilead Sciences develops and commercializes prescription medicines, including HIV/AIDS treatments (such as Biktarvy and Genvoya), liver disease drugs (such as Epclusa and Vemlidy), oncology medicines (such as Yescarta and Trodelvy), and Veklury for COVID-19, and it earns money primarily from selling these medicines and from related royalty and other revenues.

Profit power is driven by recurring commercial demand for its branded, multi-indication medicine franchises, with results concentrated in a few major revenue streams (HIV and Veklury) and supported by smaller oncology and royalty or other revenue.

Revenue by segment (latest quarter)
HIV$4.2B
Veklury$1.5B
Onco$0.6B
Other$0.4B

Business quality (Strong): Strong visibility into product-level revenue drivers, but the available breakdown is approximate, since only product revenue candidates (not explicitly confirmed reportable segments) were provided.

Valuation: At 17× earnings, GILD trades in line with the Pharmaceutical Products average (17×). Note: one-time items can distort reported P/E.

Bull case

  • Large HIV portfolio with multiple branded products: The company sells a broad set of HIV/AIDS medicines, and HIV revenue is the largest single operating driver provided (HIV revenue 4.2B).
  • Multiple growth engines across disease areas: Beyond HIV, the company commercializes Veklury for COVID-19 and several oncology medicines, with Veklury revenues at 1.5B and oncology revenue at 0.58B.

Bear case

  • High dependence on a small number of revenue streams: HIV revenue (4.2B) and Veklury revenues (1.5B) together make up the majority of the provided quarterly revenue, so unfavorable movement in either stream could weigh on overall results.
  • COVID-19 product exposure: Veklury is specifically for treatment of coronavirus disease 2019, which creates an inherent risk that demand could change over time as the pandemic evolves.
