Germany-based biotechnology firm BioNTech SE (BNTX) on Thursday said that it intends to acquire its peer CureVac (CVAC) in an all-stock transaction. CVAC stock shot up by about 32% in pre-market trading.

Under the terms of the deal, each CureVac share will be exchanged for approximately $5.46 in BioNTech American depositary shares, resulting in an implied aggregate equity value for CureVac of roughly $1.25 billion.

BioNTech also stated that the purchase consideration is subject to a collar mechanism. If the 10-day volume-weighted average price of BioNTech ADS shortly before the closing of the offer exceeds $126.55, the exchange ratio would be 0.04318, and if the price is lower than $84.37, the exchange ratio would be 0.06476.

Upon closing of the transaction, CureVac shareholders are expected to own between 4% and 6% of BioNTech.

BioNTech will own 100% of CureVac and its subsidiaries, and it will integrate CureVac’s research and manufacturing site in Tübingen.

The companies stated that the acquisition will create long-term value for shareholders of both companies and will build on BioNTech’s track record in messenger ribonucleic acid (mRNA) commercialization, including its mRNA-based COVID-19 vaccine developed in collaboration with Pfizer Inc (PFE).

CureVac is developing a class of medicines in oncology and infectious diseases based on mRNA. BioNTech said that the transaction will strengthen the research, development, manufacturing, and commercialization of mRNA-based cancer immunotherapy candidates.

The transaction is expected to close in 2025, subject to the completion of customary closing conditions and receipt of regulatory approvals.
