Lonza is one of the world's most important enablers of the pharmaceutical and biotechnology industries, providing the manufacturing infrastructure that allows drug developers to bring complex therapies from laboratory discovery to commercial supply. Founded in 1897 and headquartered in Basel, Switzerland, the company has grown from its origins in electrochemical production into a leading contract development and manufacturing organisation (CDMO), listed on the SIX Swiss Exchange under the ticker LONN.
Lonza's core strength lies in biologics manufacturing, where it operates large-scale mammalian cell culture, microbial fermentation, and downstream processing capabilities across facilities in the United States, Europe, and Asia. The company is a principal manufacturing partner for some of the world's best-selling biologics, including monoclonal antibodies and recombinant proteins. Its Ibex Solutions platform offers modular, flexible manufacturing designed to compress timelines and reduce capital requirements for clients developing next-generation therapies.
In recent years Lonza has invested substantially in cell and gene therapy manufacturing, establishing dedicated facilities and capabilities for viral vector production, including lentiviral and adeno-associated virus (AAV) vectors, as well as plasmid DNA manufacturing. These services address the rapidly expanding pipeline of advanced therapy medicinal products (ATMPs) requiring specialist GMP production.
Beyond biologics, Lonza has longstanding expertise in small molecule active pharmaceutical ingredient (API) synthesis, including highly potent API handling and peptide manufacturing. Its Capsugel-derived capsule and dosage form business, integrated following the 2017 acquisition, extends its offering into oral drug delivery formats used across multiple therapy areas.
With dozens of manufacturing sites globally and a workforce of tens of thousands, Lonza serves clients ranging from emerging biotech companies to major multinational pharmaceutical groups. Its scale, regulatory track record, and breadth of technical capabilities make it a reference partner across oncology, immunology, rare diseases, and infectious disease programmes.
