Europe Expires FirstNarrow moat

Gilead Sciences (GILD) — moat facet

Gilead's key European patents end in 2027 and 2033, years before the US dates, making Europe a preview of the 2030s.

Europe gives an early view of what American expiries will look like. The primary European patents on Descovy, Vemlidy and Odefsey run to 2027, and Biktarvy's to 2033, against 2031, 2031, 2032 and 2036 in the United States1.

Europe runs three to four years ahead of America.

Europe is a smaller market for Gilead. Product sales there were $4,617 million in 2025 against $20,816 million in the United States2, so Europe was about 16% of product sales3. Biktarvy's European sales were $1,676 million4.

That makes Europe the test case. In 2027 three tenofovir alafenamide products lose primary European protection, and in 2033 Biktarvy does. Gilead's European revenue after those dates will show how quickly HIV patients move to generics when a cheaper equivalent exists, and how well Gilead's newer products hold them.

It also shows the scale gap. Gilead's HIV sales in Europe were $2,392 million in 2025 against $16,904 million in the United States5. Europe's expiries will teach a lesson cheaply; America's will cost a great deal more.

Europe also has a different shape of franchise. Of Gilead's $4,617 million of European product sales in 2025, $2,392 million was HIV6, about half, against about 81% of US product sales7. Liver disease and oncology carry more weight there, so a European HIV generic hurts a smaller share of the regional business than the same event would in America.

The European numbers after 2027 are the earliest evidence of the 2030s. If Gilead's European HIV sales fall more than 15% in 2028, the American expiries will be more painful than the switching strategy assumes.
