David A. Ricks
Chairman and Chief Executive Officer
Legacy
David Ricks assumed the role of CEO in January 2017 and has presided over arguably the most transformative period in Lilly's modern history, overseeing the strategic refocusing that concentrated the company's resources on a smaller number of high-conviction therapeutic areas and produced the tirzepatide commercial triumph. Ricks championed the Loxo Oncology acquisition, the sustained investment in the Alzheimer's program despite years of setbacks and skepticism, and the unprecedented manufacturing expansion program that the company has committed to in response to tirzepatide demand. Under his leadership, Lilly's market capitalization grew from approximately $80 billion in early 2017 to peak values exceeding $700 billion in 2024—a roughly 775 percent increase that reflects both the commercial success of his strategic choices and the market's confidence in the pipeline he has assembled.
