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.

Implications of Inventory Write-Downs and Other Charges related to COMIRNATY 21 1. Inventory write-downs and other charges, jointly referred to as charges, were mainly triggered by market demand shifting from pandemic into endemic setting as well as the companies following the guidance from regulatory authorities on strain changes leading to the introduction and marketing of updated COVID-19 vaccines better matched to circulating sublineages. 2. Including all effects derived from the information received from BioNTech’s collaboration partner. 3. Inventories and provisions for production capacities derived from contracts with Contract Manufacturing Organizations (CMOs) that became redundant are measured reflecting contractual compensation payments under the collaboration agreements. Manufacturing variances are reflected as transfer price adjustment impacting sales to the collaboration partner and the share of the collaboration partner’s gross profit respectively once assessed as highly probable to occur. Amounts are only cash-effectively shared with the partner once materialized. Please refer to the Annual Report on Form 20-F for the year ended December 31, 2022, as well as the Quarterly Report as of and for the three and nine months ended September 30, 2023, filed as an exhibit to BioNTech’s Current Report on Form 6-K filed on November 6, 2023. Any changes to the assessment will be recognized prospectively. Write-downs / other charges by Pfizer Identified on the collaboration partner’s side Write-downs / other charges by BioNTech Identified on BioNTech’s side Initially announced estimate Up to €0.9 bn Actual YTD 2023 effect recorded €0.6 bn2 (thereof €0.5 bn in Q3 2023) BioNTech already reflected a large portion of write-downs / other charges in 2022 financial results and a smaller portion in 2023 Charges1 mainly reflect that market demand has shifted from pandemic to endemic, flu-like setting; Under the gross profit-sharing agreement charges are borne by both collaboration partners Reducing Pfizer’s gross profit, hence BioNTech’s revenues Reducing BioNTech’s gross profit3
