BioNTech has extended beyond its identity as a COVID-19 vaccine manufacturer. While its revenue has been steadily declining, including a 35.4% drop, year over year, to 118.1 million euros (roughly $134 million) in the first quarter, the German company reported 16.8 billion euros (approximately $18 billion) in cash, cash equivalents, and security investments. Any buyer would essentially be buying a world-class clinical platform at a steep structural discount, with BioNTech's own cash offsetting a large portion of the up-front purchase price.

BioNTech has a late-stage oncology and ADC pipeline

Rather than buying early-stage science, an acquirer would step into a mature oncology portfolio. BioNTech has more than 25 phase 2 and phase 3 clinical trials running. Some of the high-potential programs include Pumitamig, a bispecific immunomodulator currently being scaled into five new pivotal trials for lung, breast, and gastric cancers, and Gotistobart, a CTLA-4 antibody showing strong overall survival trends in non-small cell lung cancer, with pivotal phase III interim data due later this year.

A legacy pharma company facing its own patent cliffs could immediately absorb a late-stage portfolio spanning messenger RNA (mRNA) immunotherapies, next-gen immunomodulators, and highly sought-after antibody-drug conjugates (ADCs). BioNTech has six late-stage clinical readouts expected this year.

New BioNTech leadership may be more open to a buyout

Co-founders Uğur Şahin and Özlem Türeci hold voting control over the company's direction, and they have been committed to keeping BioNTech independent to realize their 2030 vision of becoming a fully integrated, multi-product oncology powerhouse.

However, with the co-founders scheduled to transition out of management by the end of 2026 to launch a separate, early-stage mRNA innovation spinoff, the corporate governance structure is shifting.

It's still a good time to buy this duo

Both companies have seen their shares drop by more than 13% over the past year. Neither is profitable, so they may find that taking a buyout makes more sense for the success of their promising pipelines.

It's easy to see Johnson & Johnson as a potential suitor for Legend Biotech, as the two companies already partner on Carvykti sales. BioNTech has partnered with Pfizer and Bristol Myers Squibb, so those two would be potential suitors.

There are other large pharmaceutical companies facing patent cliffs for their therapies and could benefit from acquiring Legend's or BioNTech's pipeline. There's a risk in buying any unprofitable biotech stock, but the potential upside is evident for these two.
