Why is Gilead Sciences Inc (GILD) stock moving?

Gilead has moved from about $156 on Oct 23 to a $170.87 close on Nov 10, a gain of roughly 9%, after reporting Q3 results on Oct 29. The 8-K excerpt does not include the reported figures, so this analysis relies on the price action and the news flow. The strongest recent evidence is clinical and regulatory: Phase 3 IDEAL data for Livdelzi showed 75.4% ALP normalization versus 16.1% on placebo, PURPOSE 5 showed higher persistence for twice-yearly lenacapavir, and the FDA approved a long-acting lenacapavir for HIV prevention on Nov 2. Analysts have lifted targets repeatedly, from Bernstein at $175 and JPMorgan at $190 to Maxim at $200, DZ Bank at $191 and Daiwa at $174, which averages about $184 and implies roughly 8% upside from the last close. The price has been volatile: it peaked intraday at $176.58 on Nov 5 on 11.4M shares, then closed at $167.57 the same day, a reversal that points to supply near $175. Volume was heavy on Oct 30 (11.4M) and Nov 5, and has eased to about 4.8M on Nov 10. Holding above the $164-167 zone since Nov 6 suggests buyers are defending that area. Risks include the pending FDA decision on a new cell therapy, which adds event risk, and a generic lenacapavir that could widen access in lower-income countries at lower prices.

News behind the analysis

About Gilead Sciences Inc

Healthcare · Biotechnology

Gilead Sciences is a large California-based biopharmaceutical company best known as the leading maker of HIV medicines, including the top-selling treatment Biktarvy and the twice-yearly HIV prevention shot Yeztugo. It is expanding beyond HIV into cancer, liver disease and inflammation, partly through acquisitions such as Arcellx, Ouro Medicines and Tubulis in 2026.

How it makes money

Gilead earns nearly all of its revenue by selling prescription drugs, and HIV medicines make up the large majority. Biktarvy alone brought in about $14 billion of roughly $29 billion in total revenue in 2025. Other sales come from cancer drugs (Trodelvy and the cell therapies Yescarta and Tecartus), liver-disease drugs (Livdelzi plus hepatitis B and C treatments) and the COVID antiviral Veklury, whose sales are shrinking. A smaller amount comes from royalties and collaborations. The company expects about $31 billion in total revenue for 2026.
