Overview

  • BioNTech announced it will acquire CureVac for $1.25 billion to strengthen its mRNA-based oncology and immunotherapy portfolio.
  • CureVac shareholders will receive BioNTech shares valued at a 55% premium on the average stock price over the past three months.
  • The deal, approved by both companies’ boards, is subject to regulatory clearances and is expected to close by the end of 2025.
  • Germany’s KfW public bank, which owns 13.3% of CureVac, and shareholders holding over one-third of the company have committed to the sale despite an ongoing 2022 patent lawsuit between the firms.
  • BioNTech has launched an up to $11.1 billion collaboration with Bristol Myers Squibb to develop a new cancer antibody as competitors such as Moderna and Merck advance their own mRNA oncology pipelines.
