HIVWide moat

Gilead Sciences (GILD) — moat facet

HIV is 70.5% of Gilead's revenue, grew about 4% a year from 2019 to 2025 and 12% in the latest quarter on treatment price and prevention growth.

HIV is most of Gilead. Product sales were $20,752 million in 2025, 70.5% of total revenues12, and $5,693 million in the second quarter of 2026, up 12%3.

Biktarvy is two-thirds of the line.

What is inside is a family of regimens on a common backbone of emtricitabine and tenofovir alafenamide. Biktarvy sold $14,334 million in 2025, Descovy $2,758 million, Genvoya $1,498 million and Odefsey $1,167 million, and Gilead booked $495 million from its components in Janssen's Symtuza4. "Other HIV", about $500 million5, includes Atripla, Complera, Emtriva, Stribild, Sunlenca, Truvada, Tybost and Yeztugo6.

The history is one of steady growth through internal replacement. HIV sales were $16,438 million in 2019, $16,938 million in 2020 and $16,315 million in 20217, then $17,194 million and $18,175 million in 2022 and 20238 and $19,612 million in 20249. That is about 4% a year10, with one dip, while older products such as Genvoya and Truvada shrank and Biktarvy and Descovy grew.

The line is paid for mainly through American insurers and government programmes. Of the 2025 total, $16,904 million came from the United States, $2,392 million from Europe and $1,456 million from the rest of the world11. Most US sales go through three wholesalers, and gross-to-net deductions took 41% of gross product sales across the company12.

Gilead reports no profit by product. The company's product gross margin was 78.4% in 202513; HIV regimens, sold at scale from established manufacturing, are likely the highest-margin part of it, though that is an inference rather than a disclosure.

Growth has two engines now. Treatment grows slowly as patients are added and prices rise; Biktarvy grew 7% in the second quarter14. Prevention grows fast: Descovy 48% and Yeztugo from $15 million to $232 million15.

The outlook has two dates. Medicare's negotiated price for Biktarvy starts in 202816; its US generics cannot enter before April 203617. Between them, Gilead plans to move patients to lenacapavir-based products patented to 203718.

Not every part of the line is growing. Gilead's revenue from its components in Janssen's Symtuza fell from $592 million in 2024 to $495 million in 202519, and Genvoya and Odefsey fell too20. Inside a line that grew about 6%21, the older products are shrinking by design; the growth comes from Biktarvy, Descovy and Yeztugo.

This line decides Gilead. If HIV sales grow less than 2% in 2028, the first year of the Medicare price, the franchise will have become a slow-growth annuity rather than a growing one.

Moat trajectory: Holding steady

HIV +12% in Q2 2026; Medicare price from 2028.

The number that tests this moat
Reported
HIV product sales, latest quarter
$5,693M (Q2 2026, +12% from $5,088M)

The core of Gilead; growth below 2% in 2028 would mark the Medicare price taking hold.
