As of February 2, 2021, based on the doses to be delivered in 2021 primarily under agreements entered into as of February 2, 2021 (including, among others, agreements with the U.S. government to supply 200 million doses, the European Commission to supply 300 million doses, the Japanese government to supply 144 million doses and COVID-19 Vaccines Global Access (COVAX) for up to 40 million doses in 2021, subject to the negotiation and execution of additional agreements under the COVAX Facility structure), we forecasted approximately $15 billion in revenues in 2021 from BNT162b2, with gross margin to be split evenly with BioNTech. This forecast was based on doses mostly covered under agreements entered into as of February 2, 2021 and did not include all of the doses we can potentially deliver by the end of 2021. Pfizer and BioNTech continue to enter into agreements with governments for additional doses, including, among others, the exercise by the U.S. government of an option for an additional 100 million doses and an agreement with the European Commission for an additional 200 million doses to be delivered in 2021. Accordingly, this forecast may change based, in part, on these and future additional agreements that may be signed and as circumstances warrant.

Adjusted IBT margin guidance for BNT162b2 incorporates the current expectation for revenues for the product, less anticipated Adjusted costs to manufacture, market and distribute BNT162b2, including applicable royalty expenses and a 50% gross margin split with BioNTech, as well as shared R&D expenses related to BNT162b2 and costs associated with other assets currently in development for the prevention and treatment of COVID-19. It does not include an allocation of corporate or other overhead costs.
