The future of German biotech firm CureVac hangs in the balance as shareholders prepare for a decisive extraordinary general meeting on November 25, 2025. The outcome will determine whether BioNTech’s proposed $1.25 billion acquisition proceeds or collapses, affecting thousands of investors who have backed the mRNA technology pioneer.
Acquisition Mechanics and Critical Threshold
BioNTech formalized its takeover bid on October 22, offering CureVac shareholders approximately $5.46 per share through an exchange for BioNTech American Depositary Shares (ADSs). Rather than cash, the transaction involves a sophisticated price protection mechanism designed to mitigate stock volatility.
Under this arrangement, if BioNTech’s share price exceeds $126.55, CureVac investors would receive 0.04318 ADSs per share. Should BioNTech shares fall below $84.37, the exchange ratio increases to 0.06476 ADSs per CureVac share. The tender offer period concludes at 9:00 AM EST on December 3, 2025, but the pivotal event remains the November 25 shareholder vote.
Approval requires consent from at least 80% of outstanding CureVac shares, though BioNTech retains the option to lower this threshold to 75% if necessary. German regulatory authorities already granted their approval in October, removing one significant barrier to the transaction.
Strategic Rationale Behind the Move
BioNTech’s leadership has been transparent about their motivations for pursuing CureVac. CEO Ugur Sahin emphasized that the acquisition would strengthen his company’s oncology strategy, particularly in mRNA-based cancer immunotherapies and the bispecific antibody candidate pumitamig (BNT327).
The transaction would provide BioNTech access to CureVac’s proprietary mRNA platform and optimized lipid nanoparticle technology, complementing its existing capabilities. This strategic consolidation aims to reinforce BioNTech’s dominant position within the competitive mRNA marketplace.
Should investors sell immediately? Or is it worth buying CureVac?
Of particular interest is CureVac’s oncology pipeline, including the glioblastoma candidate CVGBM. Early clinical data has shown promise, with Phase 1 studies demonstrating antigen-specific T-cell responses in 77% of patients receiving the treatment.
Financial Position and Pipeline Assets
Despite projecting quarterly losses of $0.17 per share on revenues of approximately $21.4 million, CureVac maintains substantial valuable assets beyond its immediate financial metrics. The company’s financial stability has been bolstered by a €400 million payment from GSK, providing sufficient capital to fund operations through 2028.
CureVac’s development portfolio includes an off-the-shelf program targeting non-small cell lung cancer, scheduled to enter Phase 1 trials during the second half of 2025. The GSK partnership has also yielded encouraging Phase 2 data for a seasonal influenza program, which will advance to Phase 3 in 2025 and is expected to generate significant milestone payments for CureVac.
Shareholder Considerations and Voting Procedures
The extraordinary general meeting will address not only the acquisition itself but also proposed leadership changes. BioNTech has nominated several candidates for key positions, including CFO Ramón Zapata Gomez for a managing director role and Chief Legal Officer James Ryan for the supervisory board.
Shareholders who opt not to participate in the exchange offer will later receive equivalent consideration through a restructuring process, though this may involve deduction of a 15% Dutch withholding tax. The record date for determining voting rights was October 28, 2025, with registration closing on November 20.
The central question facing investors is whether sufficient shareholders will accept the premium offered by BioNTech or instead choose to maintain faith in CureVac’s long-term potential as an independent mRNA developer with a promising therapeutic pipeline.
