Deal or Case news
29.09.2025
Merus N.V. (Nasdaq: MRUS) and Genmab A/S (Nasdaq: GMAB) announced today that they have entered into a transaction agreement pursuant to which Genmab intends to acquire all the shares of Merus, a clinical-stage biotechnology company, for USD 97 per share in an all-cash transaction representing a transaction value of approximately USD 8 billion.

The proposed acquisition of Merus is expected to meaningfully accelerate Genmab’s shift to a wholly owned model, expanding and diversifying the company’s revenue, driving sustained growth into the next decade and contributing to Genmab’s evolution into a biotechnology leader. The addition of petosemtamab, Merus’ lead asset, to Genmab’s promising late-stage pipeline is a compelling strategic fit with Genmab’s portfolio and aligns with Genmab’s expertise in antibody therapy development and commercialisation in oncology.

We feel privileged to have represented Merus for nearly a decade and now towards a transformational transaction that is expected to deliver value to Merus, its business, its shareholders and relevant patient populations
