Losing vs buying, by area

AreaAt risk by 2037Acquisitions since 2023
Cardiometabolic$40.8B$1.0B
Oncology$5.7B$4.65B
Immunology$3.6B$6.8B
Neuroscience–$9.1B

Eli Lilly has the most revenue at risk in cardiometabolic, but has spent the most on acquisitions in neuroscience. At risk is 2025 sales of tracked drugs losing US exclusivity by 2037; acquisitions are the headline value of counted deals closed since 2023.

How to read this

The two figures measure different things. Revenue at risk is what the drugs earned in 2025. A deal's value is what Eli Lilly paid, not the sales it will bring in. None of the companies it bought had an approved product at closing, so any sales from them are years away and may never arrive. So this page shows the figures side by side rather than claiming how much of the gap the deals fill.
