What SERB Pharmaceuticals does

SERB Pharmaceuticals is a global specialty pharmaceutical company headquartered in Luxembourg with origins dating to 1951 in Paris (as Société d'Études et de Recherches Biologiques). Following Charterhouse Capital Partners' acquisition of a majority stake in September 2017, with co-sponsorship from Partners Group and Merieux Equity Partners, the company executed a series of transformative acquisitions — Veriton Pharma (2020), BTG Specialty Pharmaceuticals (2021), Xermelo ex-US/Japan rights from Ipsen (2022), Vistogard and Xuriden from Wellstat (2023), RSDL from Emergent BioSolutions (2024), Aurlumyn from CiVi Biopharma (2024), and Y-mAbs Therapeutics (2025) — building a portfolio of 70+ medicines focused on three franchises: rare diseases (oncology, neurology, metabolic), emergency and critical care, and CBRN medical countermeasures. The company operates a hybrid manufacturing model anchored by a proprietary polyclonal antibody manufacturing platform (one of the few globally capable of commercial-scale production with 20+ years of process know-how and two FDA-approved products) combined with in-house facilities in Wales, Australia, Utah, and Mississippi, supplemented by European contract manufacturers.

SERB generates revenue primarily through direct sales of its specialty pharmaceutical products to hospitals, healthcare systems, first responders, and emergency preparedness agencies in 18 countries across the US, Europe, and the Middle East, with a distribution partner network extending reach to 80–100+ countries. Secondary revenue mechanics include licensing and acquisition-integration economics (e.g., the €115M Idefirix licensing deal with Hansa Biopharma), government and military procurement for CBRN products such as RSDL and potassium iodide, specialty pharmacy channels in the US (BioMatrix, Cardinal Health), and direct-to-consumer e-commerce for ThyroSafe. GTM motion combines enterprise field sales, regulatory and KOL engagement, patient association partnerships, and 24/7 medical information services. The company is structured under SERB S.à.r.l. (Luxembourg) as the parent holding entity, with operating subsidiaries including BTG International (US), Protherics UK Ltd, Veriton Pharma, Y-mAbs Therapeutics, and SERB GmbH / SERB SAS / SERB Sp. z.o.o. / SERB S.A. as regional market entities across Europe.
