Results of BioNTech Rights Offering

BioNTech SE (Nasdaq: BNTX) (“BioNTech” or the “Company”) a clinical-stage biotechnology company focused on patient-specific immunotherapies for the treatment of cancer and infectious diseases, had previously announced an offering of rights to subscribe for new ordinary shares and new American Depositary Shares (“ADSs”) representing new ordinary shares. The respective subscription periods expired on August 14, 2020 (the “expiration date”). Pursuant to the rights offering, subscribers will purchase an aggregate of 16,124 ordinary shares, represented by 16,124 ADSs, at the subscription price of $93.00 per ADS. Delivery of the ADSs in the rights offering is expected to be made on or about August 27, 2020.

BioNTech expects to use the net proceeds that it receives from the exercise of the subscription rights issued in the rights offering for general corporate purposes.

If a holder of ordinary shares or ADSs did not exercise its ordinary share or ADS subscription rights prior to the expiration date, such rights have expired and are void and have no value, and such rights will not affect the number of ordinary shares (including those represented by ADSs) held by such holder.

A registration statement on Form F-1, as amended, relating to the rights and ordinary shares was previously filed with the Securities and Exchange Commission (the “SEC”) and declared effective on July 24, 2020. A prospectus relating to the rights offering was filed with the SEC on July 23, 2020 and is available on the SEC’s website.
