In a significant consolidation of the mRNA therapeutics field, BioNTech has reached an agreement to acquire its rival CureVac through an all-stock transaction valued at $1.25 billion. The deal, announced on Thursday, comes just weeks before the two companies were scheduled to meet in a German courtroom over patent disputes related to messenger RNA technology.
Under the terms of the acquisition, CureVac shareholders will receive BioNTech shares worth approximately $5.46 for each CureVac share they hold, resulting in CureVac stockholders owning between 4% and 6% of BioNTech following the deal’s completion.
The merger brings together two companies with notably different trajectories during the COVID-19 pandemic. While BioNTech, in partnership with Pfizer, successfully developed the first approved COVID-19 vaccine, CureVac’s vaccine candidate failed to demonstrate sufficient efficacy in clinical trials, leading to its abandonment.
The timing of the acquisition is particularly noteworthy, as it precedes scheduled patent litigation between the two companies. CureVac had previously filed lawsuits against BioNTech, claiming infringement of four patents, with two of these patents having been upheld by the European Patent Office. A trial was set to begin on July 1 in a Dusseldorf regional court, with a separate U.S. trial scheduled for September 8 in Virginia.
Industry analysts suggest that BioNTech’s primary motivation for the acquisition may be to avoid potentially costly patent litigation outcomes. According to Evercore ISI analyst Umer Raffat, BioNTech could have faced up to $3 billion in royalty payments if CureVac had prevailed in court, making the $1.25 billion acquisition price comparatively attractive.
Beyond resolving legal disputes, the merger also strengthens BioNTech’s oncology portfolio. Both companies have been actively pursuing cancer therapeutics, with BioNTech maintaining a diverse pipeline including cell therapies, mRNA vaccines, and bispecific antibodies. CureVac’s cancer research programs, though earlier in development, include a brain cancer vaccine that has produced initial clinical data and a lung cancer immunotherapy recently approved for human trials.
Following its unsuccessful COVID-19 vaccine development, CureVac had pivoted its strategy, selling most of its influenza and COVID-19 vaccine rights to GSK and redirecting its focus toward cancer research. However, Leerink Partners analyst Mani Foroohar notes that the merger with BioNTech could benefit CureVac’s early-stage oncology pipeline, particularly in the competitive field of personalized cancer vaccines where BioNTech has established expertise.
Despite the strategic benefits in cancer research, Evercore ISI’s analysis suggests that the deal assigns minimal value to CureVac’s development pipeline, indicating that the primary driver of the acquisition may be the resolution of patent disputes rather than the expansion of research capabilities.
The merger represents a significant shift in the mRNA therapeutics landscape, combining two pioneering companies in the field and potentially setting the stage for accelerated development of mRNA-based cancer treatments. The deal also highlights the growing importance of intellectual property in the biotechnology sector, where patent disputes can significantly impact company valuations and strategic decisions.
