Eli Lilly and Company is one of the oldest continuously operating pharmaceutical companies in the United States, founded in Indianapolis in 1876 by Colonel Eli Lilly, a Civil War veteran who insisted on rigorous quality standards at a time when patent medicines were largely unregulated. That founding conviction shaped a company that today ranks among the world's largest pharmaceutical enterprises by market capitalisation, listed on the New York Stock Exchange under the ticker LLY.
Lilly's most consequential scientific legacy is in diabetes care. The company played a central role in the commercialisation of insulin in the early 1920s and has remained a dominant force in the category ever since. Its portfolio of insulin products and GLP-1 receptor agonist treatments has placed it at the forefront of the global obesity and metabolic disease conversation, with Mounjaro (tirzepatide) representing one of the highest-profile pharmaceutical launches of the 2020s across both type 2 diabetes and weight management indications.
Beyond metabolic disease, Lilly operates a substantial oncology division spanning targeted therapies and immuno-oncology, alongside a long-standing neuroscience programme that has historically focused on depression, pain, and central nervous system disorders. The company has invested heavily in Alzheimer's disease research, an area where it has pursued multiple clinical programmes over several decades. Verzenio (abemaciclib) in breast cancer and Cyramza (ramucirumab) in gastric and lung malignancies anchor the oncology commercial offering.
Headquartered in Indianapolis, Indiana, Lilly operates manufacturing sites, research laboratories, and commercial offices across dozens of countries, serving patients in more than 120 markets globally. The company's R&D investment consistently ranks among the highest in the industry as a proportion of revenue, reflecting a pipeline-first culture that has defined its competitive positioning for generations.
