Thermo

Thermo Fisher Scientific is a large publicly traded life science and healthcare company that supplies analytical instruments, laboratory products, specialty diagnostics, and biopharma services to pharmaceutical, biotech, academic, clinical, and government customers. The company is also a major CRO and CDMO through brands and businesses including PPD and Patheon, supporting clinical research, development, and commercial manufacturing. In addition to tools and services, Thermo Fisher markets molecular diagnostics and companion diagnostic products, including offerings in oncology. Its business spans research-use products, clinical and diagnostic systems, and outsourced development and manufacturing, making it a broad healthcare infrastructure company rather than a therapeutics developer. For a biotech analyst, Thermo Fisher is best understood as a scaled enabling-platform company serving the full drug discovery, development, diagnostics, and manufacturing value chain.
