The Pharma Letter M&A roundup - October 2025

10 November 2025

A frenzy of M&A deals hit the pharma sector in October, with Novo Nordisk (NOV: N), Bristol Myers Squibb (NYSE: BMY), Eli Lilly (NYSE: LLY) and Novartis (NOVN: VX) the big players that announced acquisitions.

MId-size drugmakers and emerging biotechs got in on the act, too, notably Relief Therapeutics (SIX: RLF), which has agreed to merge with privately held NeuroX Group in a transaction valuing the latter company at 1 billion Swiss francs ($1.1 billion) and the former at 100 million francs.

Our table and graph below illustrate the month's deals and 2025's spending so far compared to recent years.
