Founding Story

In 1876, Colonel Eli Lilly, a pharmacist and Union Army veteran, opened a small laboratory in Indianapolis with about $1,400 of capital. At a time when unregulated patent medicines were common, he set out to make high-quality prescription drugs dispensed through physicians, an emphasis on standardized, reliable products that shaped the company's reputation.

Founders

Colonel Eli Lilly

Following his military service and early experiences in the apothecary trade, Lilly worked in various pharmaceutical and business ventures, eventually amassing enough capital to strike out on his own. In 1876, he founded Eli Lilly and Company in a small laboratory in Indianapolis, Indiana. His unyielding commitment to creating standardized, reliable, and scientifically verifiable medicines set an entirely new standard for the nascent pharmaceutical industry. Beyond his business acumen, Colonel Lilly was known as a tireless civic leader and philanthropist, dedicating significant time and resources to improving the city of Indianapolis and fostering a corporate culture that valued employee welfare and community engagement. His legacy extends far beyond the company he built, influencing the broader trajectory of American industrial philanthropy. Colonel Eli Lilly was born in 1838.

Major Acquisitions

Loxo Oncology

2019

Lilly acquired Loxo Oncology in January 2019 for approximately $8 billion to acquire a precision oncology platform built around the concept of targeting specific genomic alterations in cancer regardless of tumor type. Loxo had pioneered the development of selective kinase inhibitors designed to minimize off-target effects while achieving exceptional on-target potency against genomically defined cancer populations. The acquisition was intended to accelerate Lilly's transformation into a precision medicine oncology leader at a time when the company recognized that undifferentiated cytotoxic chemotherapy partnerships were not a sustainable competitive strategy in oncology.

Morphic Holding

2024

Lilly acquired Morphic Holding in 2024 for approximately $3.2 billion to access the company's integrin inhibitor platform, which includes MORF-057, an oral small-molecule inhibitor of alpha-4-beta-7 integrin with potential in inflammatory bowel disease including Crohn's disease and ulcerative colitis. The inflammatory bowel disease market represents a high-value segment that Lilly had not previously addressed with differentiated proprietary assets, and Morphic's oral small-molecule approach offered a potential advantage over existing large-molecule biologics like vedolizumab that require infusion or injection. The acquisition reflected Lilly's strategy of using its strong balance sheet and cash generation to acquire late-stage development assets that can be accelerated through its global clinical and commercial infrastructure.

POINT Biopharma

2023

Lilly acquired POINT Biopharma Global Inc. in late 2023 for approximately $1.4 billion to acquire the company's radioligand therapy (RLT) platform and manufacturing infrastructure. Radioligand therapies, which combine tumor-targeting molecules with radioactive isotopes to deliver targeted radiation to cancer cells, represent a rapidly advancing area of oncology following the commercial success of Novartis's Lutathera and Pluvicto. The acquisition gave Lilly access to POINT's proprietary radiopharmaceutical manufacturing facilities, a specialized industrial capability that is scarce globally, as well as a pipeline of RLT candidates in clinical development for prostate cancer and other malignancies.

Prevail Therapeutics

2021

Lilly acquired Prevail Therapeutics in January 2021 for approximately $1.04 billion upfront plus contingent payments to access the company's gene therapy platform targeting neurological diseases, particularly Parkinson's disease and related alpha-synucleinopathies. Prevail's lead asset, PR001, is an AAV9-based gene therapy designed to deliver a functional copy of the GBA1 gene to neurons, targeting the subset of Parkinson's disease patients with GBA1 mutations who face faster disease progression. The acquisition represented Lilly's first significant investment in the gene therapy space and reflected the company's strategy of expanding its neuroscience portfolio beyond small molecules and antibodies.
