In a significant development for the messenger RNA therapeutics field, German biotech company BioNTech has reached an agreement to acquire its rival CureVac in 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 German court over patent disputes related to mRNA technology.
Under the terms of the agreement, CureVac shareholders will receive BioNTech shares worth approximately $5.46 for each CureVac share they own, resulting in CureVac stockholders holding between 4% and 6% ownership in BioNTech following the merger’s completion.
The acquisition appears strategically timed, as it precedes a crucial July 1 trial date in Dusseldorf where the companies were set to battle over patent infringement claims. CureVac had previously accused BioNTech of infringing on four patents, with the European Patent Office having already upheld two of these claims. A separate trial was also scheduled for September 8 in Virginia, USA.
Industry analysts, including Evercore ISI’s Umer Raffat, suggest that BioNTech’s primary motivation for the acquisition may be to avoid potentially costly court judgments. Had CureVac prevailed in the patent litigation, BioNTech could have faced royalty payments estimated at up to $3 billion. Raffat noted that BioNTech likely determined that acquiring CureVac outright would be more economical than facing potential settlement costs.
The two companies’ histories intersected during the COVID-19 pandemic when both were racing to develop coronavirus vaccines. While BioNTech, in partnership with Pfizer, successfully created the first approved COVID-19 vaccine, CureVac’s vaccine candidate failed to demonstrate sufficient efficacy and was ultimately abandoned.
Following this setback, CureVac shifted its focus to cancer research and divested most of its influenza and COVID-19 vaccine rights to GSK. This strategic pivot aligns with BioNTech’s own oncology ambitions, as both companies have been developing cancer vaccines and treatments.
CureVac’s current cancer research portfolio includes a brain cancer vaccine that has shown early clinical results and a lung cancer immunotherapy that recently received approval for human trials. However, Leerink Partners analyst Mani Foroohar suggests that CureVac’s early-stage oncology pipeline would benefit from BioNTech’s expertise in personalized cancer vaccine development.
BioNTech has established itself as a leader in oncology research, investing in various therapeutic approaches including cell therapies, mRNA vaccines, and bispecific antibodies, with several programs in advanced clinical stages. Despite this potential synergy in cancer research, Evercore ISI’s analysis suggests that the deal attributes minimal value to CureVac’s pipeline, indicating that the patent litigation may have been the primary driver of the acquisition.
The merger represents a significant consolidation in the mRNA therapeutics sector and demonstrates how intellectual property disputes can reshape industry dynamics. It also highlights the continuing evolution of companies that gained prominence during the COVID-19 pandemic as they adapt their technologies and business strategies for other therapeutic areas, particularly in oncology.
The transaction, which will merge two prominent German biotechnology companies, marks another chapter in the rapidly evolving story of mRNA technology and its applications beyond infectious diseases. As the deal moves toward completion, the industry will be watching closely to see how BioNTech integrates CureVac’s assets and expertise into its expanding therapeutic portfolio.
