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 AstraZeneca 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.
