BioNTech SE filed an amended Form F-4 for an exchange offer to acquire all outstanding ordinary shares of CureVac N.V.. Each CureVac share will be exchanged for a number of BioNTech ADSs equal to $5.4641 divided by the 10‑day VWAP of BioNTech ADSs, subject to a collar that fixes the exchange ratio at 0.04318 if the VWAP is ≥ $126.55 or 0.06476 if ≤ $84.37.
The offer is scheduled to expire at 9:00 a.m. (New York City time) on December 3, 2025, unless extended. A minimum of 80% of CureVac’s issued and outstanding capital must be tendered (which may be reduced to 75% in certain circumstances). Shareholders representing approximately 57% of CureVac shares have entered tender and support agreements. Following acceptance, a subsequent offering period of at least 10 business days will be provided.
After the offer, a post‑offer reorganization is planned so that BioNTech becomes the sole owner of CureVac’s business. CureVac holders who do not tender will receive the same consideration in that process, though amounts received there may be subject to 15% Dutch dividend withholding tax in certain cases. Delivery of ADSs is expected about 10 business days after each required German capital increase becomes effective and could take up to three weeks or more.

BioNTech SE filed a Form 6-K noting that it and Bristol Myers Squibb have presented interim data from a global randomized Phase 2 trial of pumitamig (BNT327/BMS986545) in extensive-stage small cell lung cancer. The investigational bispecific antibody targets PD-L1 and VEGF-A and is being evaluated in combination with chemotherapy. According to the attached press release description, the interim Phase 2 data show encouraging antitumor activity in this patient population.
BioNTech entered a materially significant collaboration with Bristol-Myers Squibb to develop and commercialize the investigational bispecific antibody BNT327. Under the amended and restated agreement, BMS will pay $1.5 billion upfront plus $2.0 billion in non-contingent anniversary payments through 2028, and BioNTech is eligible for up to $7.6 billion in additional milestones. The parties will equally share global profits and losses and will generally split development costs equally, with adjusted sharing when one party contributes proprietary assets to a combination trial. BioNTech will initially supply clinical material and lead manufacturing transfer to BMS, after which BMS will assume commercial supply while BioNTech retains the right to supply a percentage of commercial product. Co-exclusive IP licenses and joint governance structures for development and commercialization are established.

BioNTech SE reported that a pivotal Phase 3 trial of its antibody-drug conjugate candidate trastuzumab pamirtecan (BNT323/DB-1303), developed with Duality Biologics, met its primary goal. The study, conducted by DualityBio in China, compares BNT323/DB-1303 with trastuzumab emtansine (T-DM1) in patients with HER2-positive unresectable or metastatic breast cancer who have already received trastuzumab and a taxane-based chemotherapy.
At a pre-specified interim analysis, the trial achieved its primary endpoint of progression free survival, meaning patients on BNT323/DB-1303 lived longer without their cancer worsening than those on the comparator. A detailed press release with more information on the results is referenced as an exhibit to this report.
