Drug Royalty Interest

Longevity & Biotech Royalties

Definition

A drug royalty interest is a contractual right to receive a share of revenue, royalties, milestones, or other payments tied to a pharmaceutical or biotech product.

Why it matters

Drug royalties can provide long-duration cash flow, but exposure depends on patent life, clinical outcomes, payer coverage, competition, manufacturing, and sales concentration.

Common misconceptions

  • Approved drugs still carry commercial, reimbursement, and patent litigation risk.
  • A royalty percentage is not enough; the base, deductions, and payment waterfall matter.
