Outlook updated for the 2023 Financial Year

The Company updated its COVID-19 vaccine revenue guidance and updates its previous expense and capex guidance for the 2023 financial year:

BioNTech COVID-19 Vaccine Revenues for the 2023 Financial Year:

	Initial Guidance Mar 2023	Updated Guidance Nov 2023
Estimated BioNTech COVID-19 vaccine revenues for the full 2023 financial year	~ €5 billion	~ €4 billion

The revenues estimate reflects expected revenues related to BioNTech’s share of gross profit from COVID-19 vaccine sales in the collaboration partners’ territories, from direct COVID-19 vaccine sales to customers in BioNTech’s territory and expected revenues generated from products manufactured by BioNTech and sold to collaboration partners.

Revenue guidance is based on various assumptions. These include, but are not limited to, expectations regarding: transitions in the purchasing environment; the timing and receipt of regulatory approvals and recommendations; the progress of vaccination campaigns; and seasonal variations in SARS-CoV-2 circulation and vaccination uptake.

Several factors drive the Company’s adjusted revenue guidance. Such factors include BioNTech’s and Pfizer’s lower than previously forecast revenue expectations for the full 2023 financial year, which take into account delays in the expected timing of regulatory approvals, as well as the effects of Pfizer’s recently-announced write-downs and other charges.

While fewer primary vaccinations and lower population-wide levels of boosting are anticipated overall compared to the same period in prior years, vaccine adaptation and seasonal trends are expected to lead to demand peaks in the autumn and winter compared to other seasons. As a result of later-than-anticipated regulatory approvals and their effect on national vaccination campaign timelines, expected sales have shifted to future periods. In general, the Company continues to remain largely dependent on revenues generated in its collaboration partner’s territories.

In addition, BioNTech's revenues have been affected by the inventory write-downs and other charges related to COMIRNATY that were previously announced by the Company’s collaboration partner Pfizer. As a result of the Company’s continued assessment of these write-downs and other charges, the Company has determined that the charges originating on BioNTech’s end had largely already been reflected in the Company’s financial results for the 2022 financial year, and to a smaller extent, continued to be reflected during 2023. Ultimately, the initial estimate of “up to €0.9 billion” impact has been refined by the Company. The impact from the collaboration partner's charges onto the Company's revenues has been identified to be €0.6 billion for the nine months ended September 30, 2023 and €0.5 billion for the three months ended September 30, 2023, which is reflected in the revised revenues guidance.

Planned 2023 Financial Year Expenses and Capex4:

	Initial Guidance Mar 2023	Updated Guidance Nov 2023
R&D expenses5	€2,400m - €2,600m	€1,800m - €2,000m
SG&A expenses	€650m - €750m	€600m - €650m
Capital expenditures for operating activities6	€500m - €600m	€200m - €300m
