Lexicon Pharmaceuticals (NASDAQ: LXRX) is a biopharmaceutical company that discovers, develops, and commercializes small-molecule drugs targeting diseases with unmet medical need. Revenue comes from net product sales, licensing fees, and royalties tied to partnerships with larger pharmaceutical companies. The company's lead asset is sotagliflozin, an SGLT1/2 inhibitor approved in the United States. In October 2024, Lexicon granted Viatris Inc. an exclusive, royalty-bearing license to develop and commercialize sotagliflozin in an international territory, receiving a $25 million upfront payment with eligibility for up to $12 million in regulatory milestones, up to $185 million in sales milestones, and tiered royalties ranging from low double-digit to upper-teens percentages of annual net sales. The company continues to advance additional internal drug candidates, including LX9851 and pilavapadin, and reported third-party R&D services costs of $33.0 million in FY2025, down 42% from $56.7 million in FY2024. Lexicon operates at a net loss across all reported periods through FY2025.

Revenue model

Three revenue streams: net product revenue from direct commercial sales, licensing revenue from upfront and milestone payments under partnership agreements, and royalties from licensee net sales. The Viatris agreement illustrates the model: $25 million upfront, milestone-contingent payments, and tiered royalties on international sotagliflozin sales.
