What the 2024 $1B+ tape is really saying

A few patterns jump out:

1) Big Pharma paid up for modality platforms, not just single assets.

Radioligands (Novartis–Mariana; AZ–Fusion), RNA/CV biology (Novo–Cardior), and differentiated biologics (GSK–Aiolos) reinforce that “platform leverage” still commands premium checks. 

2) Milestones are back as a risk-transfer tool.

Multiple 2024 deals lean heavily on contingent value and “up to” math—buyers keep headline size while pushing real payout behind clinical/regulatory proof (e.g., Mariana, HI-Bio, EyeBio, Modifi). 

3) Therapeutic “gravity wells” stayed consistent: oncology, immunology, and rare disease.

Even with noisy macro, the biggest checks clustered where probability-adjusted revenue still pencils: oncology (including radiopharma), immune-mediated disease, and specialty/rare categories.
