Worth noticing: Shared-drug revenue is credited to each company based on what it reports, avoiding double-counting in the tracker’s totals.

Field notes

The chart groups each tracked drug by the first year a US generic or biosimilar can launch, and sizes its block by 2025 worldwide sales. Company views compare tracked exposure with company revenue; the page cautions that tracked drugs may not capture a company’s full exposure. Its date labels distinguish fixed dates from estimates based on patent expiry, and table entries link to sources.
