Maker of Omnipod, a tubeless insulin pump that handles dosing automatically.
Big pharma6 companies
Large, diversified pharmaceutical groups with broad portfolios across therapeutic areas.
Two businesses under one name: Innovative Medicine, which covers immunology and oncology drugs, and MedTech, which makes medical devices and surgical equipment.
Skyrizi and Rinvoq carry the immunology franchise.
Keytruda is the centre of the oncology business, which sits next to a substantial vaccines portfolio.
Vaccines are what most people associate with Pfizer.
Opdivo made the company's name in oncology.
Spun out of Pfizer in 2013 to sell animal medicines and vaccines.
Biotech & innovation11 companies
Innovation-driven biotech companies focused on novel treatment modalities.
Long-established in biotech, with oncology and haematology at the centre of the portfolio, immunology beside it and a line in bone disease.
HIV treatment is the heart of it, Biktarvy above all, with cell therapy in oncology growing alongside.
Cystic fibrosis medicines carry the business.
Antibody engineering underpins the whole portfolio, from Eylea in ophthalmology to Dupixent, partnered with Sanofi, in immunology.
Built on mRNA, the technology behind its covid vaccine.
Turns RNA interference into drugs, mostly for rare and cardiovascular disease.
Neurological disease is the whole focus, from multiple sclerosis to Alzheimer's, where Leqembi is partnered with Eisai.
Jakafi in myelofibrosis and Opzelura in dermatology anchor a portfolio split between cancer and inflammation.
Pulmonary hypertension accounts for the marketed drugs, Tyvaso, Remodulin and Orenitram among them.
Ingrezza for tardive dyskinesia, plus a wider neurology and endocrine portfolio.
Rare genetic disorders define the company.
CDMO & pharma manufacturing3 companies

Drug companies outsource clinical trials to IQVIA, and many of the same customers buy its health data and analytics.
Stoppers, syringe components and the rest of the packaging that goes around an injectable drug.
Preclinical work that drug and biotech companies choose not to do in-house: research models, safety testing, laboratory services through development, and support for cell and gene therapy.
Life science tools6 companies
Instruments, reagents and equipment for research, development and production.
Analytical instruments on one side, the reagents and consumables that feed them on the other, sold to research laboratories and pharmaceutical companies.
Cytiva supplies the equipment biologics are made with; Cepheid runs molecular diagnostics.
Laboratory analysis is the business: LC/MS and other analytical instruments, sold with the consumables and diagnostic reagents that keep them running.
Waters sells liquid chromatography and mass spectrometry systems; pharmaceutical companies and other laboratories buy them along with the consumables and software that keep them running.
DNA sequencing machines and the reagents they consume, for research and clinical genomics.
Newborn and genetic screening is the clinical end of the business; the rest supplies reagents and software to research laboratories.
Diagnostics7 companies
Tests, imaging and assays that support clinical decision-making.
In vitro diagnostics, medical devices that include the Libre glucose sensors, nutrition products and generic medicines: Abbott runs all four.
Genetic testing put to three uses: Panorama screens pregnancies, Signatera works in oncology, and a third line covers transplant medicine.
Vets are the customers.
A nationwide lab network that does routine testing at volume, with more advanced diagnostics and health data work on top.
Samples from across the US end up in Labcorp's laboratories, which handle routine clinical testing alongside genomics and specialty assays.
Women's health defines the range here, from molecular diagnostic tests to mammography systems and surgical products.
Clinical diagnostics laboratories buy one part of the range, blood typing among the uses; life science researchers buy the other, for work such as droplet digital PCR.
Medtech & devices11 companies

The da Vinci systems brought robot assistance to minimally invasive surgery and are used worldwide.
Cardiac rhythm and cardiology devices anchor a catalogue that also runs through surgical equipment, neurology and diabetes treatment.
Orthopaedic implants and surgical equipment, with Mako bringing robot assistance into the operating room.
Cardiology drives the growth, particularly electrophysiology, where Farapulse sits, and structural heart treatment.
Heart valves, delivered by catheter as with TAVR or implanted surgically.
Syringes and needles sit at the recognisable end of the range.
CPAP machines and masks for sleep apnea, sold with cloud software, next to a wider respiratory equipment range.
Imaging is the core: CT and MRI systems, plus ultrasound.
