EXPLANATORY NOTE

This registration statement contains a prospectus relating to a firm commitment underwritten offering of our ordinary shares to be represented by American Depositary Shares, or ADSs, which we refer to as the Underwritten Offering. The Underwritten Offering is part of a Global Offering that consists of (i) a rights offering to be extended to our ordinary shareholders and ADS holders, or the Rights Offering, and (ii) the Underwritten Offering. Under German law, where a company obtains binding, irrevocable agreements from certain existing shareholders not to transfer or exercise rights to be granted in a future rights offering, the company is permitted to attempt to sell the new shares represented by such rights either before or after the rights offering. Based on binding irrevocable agreements not to transfer or exercise rights that we have obtained from certain holders of our ordinary shares, representing 74.83% of our outstanding ordinary shares (including ordinary shares represented by ADSs), we intend to conduct the Underwritten Offering pursuant to this registration statement prior to the commencement of the Rights Offering.

The Rights Offering will be conducted pursuant to a separate registration statement and prospectus. The price to public that is set in the Underwritten Offering will be the subscription price for the Rights Offering. Shareholders and ADS holders as of the respective record dates for our ordinary shares and the ADSs representing our ordinary shares who have not agreed to forego exercising their rights will have the opportunity in the Rights Offering to subscribe for up to 1,681,849 new ordinary shares or new ADSs (representing approximately 0.72% of our outstanding ordinary shares) at the subscription price. ADSs PURCHASED IN THE UNDERWRITTEN OFFERING WILL NOT BE ENTITLED TO RECEIVE RIGHTS TO SUBSCRIBE FOR NEW ORDINARY SHARES OR NEW ADSs IN THE RIGHTS OFFERING. Accordingly, assuming no change in the assumed public offering price or the number of ADSs offered by us in the Underwritten Offering, as set forth on the cover page of this prospectus, a total of up to 6,681,849 ordinary shares (including new ordinary shares represented by new ADSs) may be sold in the Global Offering. We may also increase or decrease the number of ADSs we are offering in the Underwritten Offering, which would affect the number of our ordinary shares and ADSs representing our ordinary shares underlying rights granted in the Rights Offering. See “Dilution” for additional information.

The information contained in this preliminary prospectus is not complete and may be changed. We may not sell these securities until the registration statement filed with the Securities and Exchange Commission is effective.

5,000,000 American Depositary Shares

Representing 5,000,000 Ordinary Shares

We are offering 5,000,000 American Depositary Shares, or the ADSs, with each ADS representing one ordinary share, or the Underwritten Offering. The Selling Shareholder identified in this prospectus is offering 750,000 ADSs if and to the extent that the underwriters exercise their option to purchase additional ADSs described below. We will not receive any of the proceeds from the sale of ADS by the Selling Shareholder. The public offering price is $                 per ADS. ADSs representing our ordinary shares are listed on the Nasdaq Global Select Market under the symbol “BNTX.” On July 17, 2020, the last reported sale price of the ADSs on the Nasdaq Global Select Market was $85.25 per ADS.

This offering is part of a Global Offering consisting of a rights offering and this Underwritten Offering, covering, in the aggregate, up to 6,681,850 ordinary shares (including ordinary shares represented by ADSs), as described further in this prospectus. The ADSs being offered by this prospectus are being so offered based upon irrevocable, binding agreements under German law from certain holders of our ordinary shares, representing 74.83% of our outstanding ordinary shares (including ordinary shares represented by ADSs), not to transfer or exercise rights to subscribe for our new ordinary shares that we intend to grant in a rights offering we will conduct following the time at which the price to public for the offering to which this prospectus relates has been set. This offering together with the rights offering constitute the Global Offering.

Certain new and existing investors, including Pfizer Inc., have indicated an interest in purchasing up to an aggregate of $200 million in ADSs representing our ordinary shares in this offering at the public offering price of $                     and on the same terms and conditions as the other purchasers in this offering. However, because indications of interest are not binding agreements or commitments to purchase, these investors may determine to purchase fewer ADSs than they indicate an interest in purchasing or not to purchase any ADSs in this offering. It is also possible that these investors could indicate an interest in purchasing more ADSs. In addition, the underwriters could determine to sell fewer ADSs to any of these investors than the investors indicate an interest in purchasing or not to sell any ADSs to these investors.

Investing in the ADSs representing our ordinary shares involves a high degree of risk. See “Risk Factors” beginning on page 23 of this prospectus.

We are an “emerging growth company” and a “foreign private issuer” as defined under the U.S. federal securities laws and, as such, are eligible for reduced public company disclosure requirements. See “Prospectus Summary—Implications of Being an Emerging Growth Company and a Foreign Private Issuer” for additional information.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The underwriters have the option for a period of 30 days from the date of this prospectus to purchase an additional 750,000 ADSs from the Selling Shareholder.

Delivery of the ADSs is expected to be made on or about                 , 2020.

Risks Related to Our COVID-19 Vaccine Development Program and Our Intellectual Property

We may experience significant volatility in the market price of the ADSs representing our ordinary shares following announcements and data releases regarding our ongoing development of BNT162 as a potential COVID-19 vaccine.

Biopharmaceutical companies that are developing potential therapeutics and vaccines to combat COVID-19 and SARS-CoV-2, including BioNTech SE, have experienced significant volatility in the price of their securities upon publication of preclinical and clinical data as well as news about their development programs. For example, following the announcement of our collaborations with Pfizer and Fosun Pharma relating to the development of BNT162, our vaccine candidate program for the prevention of COVID-19, the last reported sales price of the ADSs representing our ordinary shares on the Nasdaq Global Select Market increased from $30.93 on March 13, 2020, the day before the announcement, to $92.00 on March 18, 2020, before decreasing to $46.50 on March 20, 2020. In addition to the preclinical and clinical data we and Pfizer have already disclosed in connection with our BNT162 development program, we and Pfizer intend over the coming months to make public several additional COVID-19 vaccine data readouts and clinical updates. We also expect to announce data, in due course, for the other three vaccine candidate variants that we are currently testing for the prevention of COVID-19 as part of our BNT162 program. On July 20, 2020, we announced that we and Pfizer have entered into a binding term sheet for a supply agreement with the United Kingdom. In addition, we are in late-stage discussions with several other governments and governmental bodies related to the establishment of supply agreements for BNT162, if approved. We cannot predict public reaction or the impact on the market price of the ADSs representing our ordinary shares once the terms of any or all of these supply arrangements are announced. We also cannot guarantee that the ultimate supply agreements we enter into, if any, will be for the number of doses we currently estimate and that aggregate consideration to be received under any such supply agreements will ultimately be what we currently expect. Given the attention being paid to the COVID-19 pandemic and the public scrutiny of COVID-19 development announcements and data releases to date, we expect that the public announcements we and Pfizer intend to make in the coming months regarding the ongoing development of BNT162 will attract significant attention and scrutiny and that, as a result, the price of the ADSs representing our ordinary shares may be particularly volatile during this time.

We are currently developing multiple candidate variants in our BNT162 program, which rely on different mechanisms of action, and the efficacy or safety of one variant is not indicative or predictive of the efficacy or safety of another variant.

We are currently developing four vaccine candidate variants for the prevention of COVID-19 as part of our BNT162 program. The first, which is the variant for which we and Pfizer announced Phase 1/2 data on July 1 and July 20, 2020, is BNT162b1, which utilizes nucleoside-modified mRNA (modRNA) and encodes the receptor binding domain antigen. Two of our four vaccine candidate variants, including BNT162b1, include a modRNA, one includes a uridine containing mRNA (uRNA), and the fourth variant utilizes self-amplifying mRNA (saRNA). Each mRNA format is combined with a lipid nanoparticle (LNP) formulation. The larger spike sequence is included in two of the vaccine candidate variants and the smaller optimized receptor binding domain from the spike protein is included in the other two candidate variants. Each variant has a distinct mechanism of action, and, as a result, clinical activity or safety results observed from one variant may not be indicative or

23

predictive of the efficacy or safety profile or results observed of another variant. For example, the data we recently announced for our BNT162b1 variant may differ in material respects from the safety or efficacy profile of the other vaccine candidate variants and should not be considered predictive of the safety or efficacy of our other vaccine candidate variants.

We cannot guarantee that the BNT162 variant we choose to advance into late stage clinical development will perform better than any of the variants we do not choose to advance. Further, even if we demonstrate a sufficient safety profile for BNT162 we may not be able to demonstrate sufficient efficacy in subsequent trials to obtain regulatory approval.

Based on preclinical and clinical data observed to-date, we and Pfizer have decided to progress our BNT162 development program into a Phase 2b/3 trial, which we plan to commence in late July 2020, subject to input and approval the from the appropriate regulatory bodies. For the initial Phase 2b/3 trial, we intend to select either the vaccine candidate variant for which we have already released data publicly, BNT162b1, or our modRNA vaccine candidate variant targeting the 2P-mutated full spike protein, BNT162b2. Both the BNT162b1 and the BNT162b2 vaccine candidates have received Fast Track status from the FDA. Since clinical evaluation of the BNT162b2 candidate started several weeks later than BNT162b1, only preliminary clinical data are currently available for the BNT162b2 candidate. A set of data obtained for a cohort of subjects aged to 18-55 years immunized with 10µg of BNT162b2 indicates that BNT162b2 may induce strong virus neutralizing antibody responses with titers in a similar range as observed for BNT162b1. The preliminary observations are subject to further data collection and analysis. Assessment of dose dependent immune response and safety profile as well as analysis of T cell responses is currently pending. On the basis of additional data expected to be collected and analyzed for BNT162b1 and BNT162b2 in the coming days, along with input from the FDA, we intend to select a lead candidate to take into a Phase 2b/3 trial. We and Pfizer currently expect to inform the FDA of our selection of the BNT162 candidate variant before the closing of this offering. Based on clinical data from our ongoing Phase 1/2 trials of BNT162b1 in the United States and Germany, BNT162b1 appears to be a suitable variant to advance into a Phase 2b/3 trial. If we and Pfizer ultimately determine to advance the BNT162b2 variant, we intend to base this decision on multiple factors, including the overall observed safety, tolerability and immunogenicity profiles for each vaccine candidate at different dose levels, as well as feedback from the FDA on the data collected for each candidate. If we ultimately move forward with the BNT162b2 variant, it will be due to the fact that based on our scientific judgment in light of the totality of preclinical data and clinical data available to us at the time of selection and the other factors described above, the BNT162b2 variant has better potential for clinical and commercial success. We do not plan to disclose which BNT162 variant has been selected until we receive FDA approval to commence the Phase 2b/3 clinical trial, and we do not plan to publish any data with respect to the BNT162b2 variant before we make our selection.

We cannot guarantee that the candidate variant that we select will ultimately prove to be the optimal variant. We and Pfizer intend to choose the variant to advance based on our scientific judgment in light of the preclinical and clinical data available to us at the time as to which variant has the best chance for success. It is possible that subsequent data regarding the variant we choose could prove to be less favorable or subsequent data from a variant that is not advanced could prove to be more favorable. In addition, it is possible that public perception of subsequently released data on the variant we choose to advance could be negative and could cause our stock price to decrease regardless of the progress of the Phase 2b/3 trial. It is also possible that the FDA may disagree with or have questions about our variant selection, which could delay the start of our Phase 2b/3 trial.

Regardless of the variant we select for Phase 2b/3, we cannot guarantee that the results from subsequent data analyses and announcements will be in line with the data that we have previously published. In addition, the total number of patients evaluated in Phase 1 is small relative to the number we intend to evaluate in Phase 2b/3 and may not be indicative of the safety or immunogenicity of BNT162 in a larger and more diverse patient population. Similarly, the samples of convalescent sera, or blood samples from people who have recovered from

24

COVID-19, used to benchmark the level of antibodies produced by subjects receiving BNT162 in clinical studies, have been taken from a small number of people and may not be representative of the antibody levels in a broader population of people who have recovered from COVID-19. Future results in clinical trials of BNT162 may not be as positive when compared to the antibody levels in other samples of convalescent sera.

Furthermore, because the assays being used to measure and analyze the effectiveness of COVID-19 vaccines have only recently been developed and are continuing to evolve, indications of immunogenicity and the duration of immunity observed in our Phase 1/2 trials may not be predictive of the achievement of clinically relevant endpoints.

In addition, by definition our Phase 1/2 clinical trials are designed to evaluate only safety and not efficacy. Positive results from these Phase 1/2 trials do not guarantee we will be able to demonstrate in our Phase 2b/3 trial that BNT162 is efficacious. More specifically, we do not yet know the levels of immunity required to prevent COVID-19 infection, and have not yet tested the ability of our vaccine candidates to prevent infection in humans. Failure to adequately demonstrate safety or to eventually demonstrate sufficient efficacy of BNT162 could delay or prevent us from receiving regulatory approval of BNT162 and there can be no assurance that BNT162 will be approved in a timely manner, if at all.

The development of our BNT162 program may divert resources from the clinical development of our other product candidates and we may not recoup our investments in the program.

Although we believe that our BNT162 program could result in an effective COVID-19 vaccine, clinical trials involve a lengthy and expensive process with an uncertain outcome. Given the severity and urgency of the COVID-19 pandemic, we have committed significant capital and resources to fund and supply the development of BNT162. However, the development of BNT162 will require us to expend financial, personnel and other resources and may cause delays in or otherwise negatively impact our other development programs, despite uncertainties surrounding the longevity and extent of COVID-19 as a global health concern. Furthermore, our business could be negatively impacted by our allocation of significant resources to a global health threat that is unpredictable and could rapidly dissipate or against which our vaccine, if developed, may not be partially or fully effective.

If we are successful in producing a vaccine against COVID-19, we may need to devote significant resources to its scale-up and development.

If any clinical trials for BNT162 are perceived to be successful, we may need to work toward the large scale technical development, manufacturing scale-up and larger scale deployment of this vaccine candidate through a variety of government mechanisms such as an Emergency Use Authorization program in the United States. We may also need to access facilities capable of rapidly manufacturing BNT162 in the volumes necessary to support large-scale clinical trials or commercial sales. If we are unable to conduct production and manufacturing activities or if our vaccine requires more doses to achieve sufficient efficacy than we expect, we may not complete our product development or commercialization efforts in a timely manner. In addition, during a global health crisis, such as the COVID-19 pandemic, where the spread of a disease needs to be controlled, closed or heavily regulated national borders will create challenges and potential delays in our development and production activities and may necessitate that we pursue strategies to develop and produce our vaccine candidate variants within self-contained national or international borders, at potentially much greater expense and with longer timeframes for public distribution.

There can be no assurance that BNT162, even if approved, would ever become profitable, due to government interest and public perception regarding a vaccine.

As a result of the emergency situations in many countries, there is a heightened risk that a COVID-19 vaccine may be subject to adverse governmental actions in certain countries, including intellectual property expropriation, compulsory licenses, strict price controls or other actions. Additionally, we may need to, or we

25

may be required by governmental or non-governmental authorities to, set aside specific quantities of doses of BNT162 for designated purposes or geographic areas. We are likely to face challenges related to the allocation of supply of BNT162, particularly with respect to geographic distribution. Thus, even if BNT162 is approved, such governmental actions may limit our ability to recoup our current and future expenses.

Furthermore, public sentiment regarding commercialization of a COVID-19 vaccine may limit or negate our ability to generate revenues from sales of BNT162. Given that COVID-19 has been designated as a pandemic and represents an urgent public health crisis, we are likely to face significant public attention and scrutiny over any future business models and pricing decisions with respect to BNT162. If we are unable to successfully manage these risks, we could face significant reputational harm, which could negatively affect the price of the ADSs representing our ordinary shares.

The regulatory pathway for BNT162 is highly dynamic and continues to evolve and may result in unexpected or unforeseen challenges.

To date, BNT162 has moved rapidly through the regulatory review process of the FDA and foreign regulatory authorities. The speed at which all parties are acting to create and test many therapeutics and vaccines for SARS-CoV-2 and COVID-19 is unusual, and evolving or changing plans or priorities within the FDA and foreign regulatory authorities, including changes based on new knowledge of COVID-19 and how the disease affects the human body, may significantly affect the regulatory timeline for BNT162. Results from clinical testing may raise new questions and require us to redesign proposed clinical trials, including revising proposed endpoints or adding new clinical trial sites or cohorts of subjects.

For example, the FDA on June 30, 2020 adopted guidance outlining the FDA’s current recommendations regarding the data needed to facilitate clinical development and licensure of vaccines to prevent COVID-19. In particular, the June 30, 2020 guidance suggests that the primary efficacy endpoint estimate for a placebo-controlled efficacy trial should be at least 50%. The guidance also includes discussion of chemical, manufacturing and controls and safety concerns. Although we intend to design any future clinical trials for BNT162 in accordance with this guidance, we cannot be certain that, as the regulatory pathway continues to evolve, we will be able to complete a clinical trial in accordance with the FDA’s guidance and regulations then in effect. A failure to complete a clinical trial in accordance with guidance and regulations then in effect could impair our ability to obtain approval for BNT162, which may adversely affect our operating results, reputation and ability to raise capital and enter into or maintain collaborations to advance our other product candidates.

Additionally, the FDA has the authority to grant an Emergency Use Authorization to allow unapproved medical products to be used in an emergency to diagnose, treat, or prevent serious or life-threatening diseases or conditions when there are no adequate, approved, and available alternatives. If we are granted an Emergency Use Authorization for BNT162, we would be able to commercialize BNT162 prior to FDA approval. However, the FDA may revoke an Emergency Use Authorization where it is determined that the underlying health emergency no longer exists or warrants such authorization, and we cannot predict how long, if ever, an Emergency Use Authorization would remain in place. Such revocation could adversely impact our business in a variety of ways, including if BNT162 is not yet approved by the FDA and if we and our manufacturing partners have invested in the supply chain to provide BNT162 under an Emergency Use Authorization.

Even if regulatory approval is received for a BNT162 vaccine candidate, the later discovery of previously unknown problems associated with BNT162 may result in restrictions, including withdrawal of the product from the market, and lead to significant liabilities and reputational damage.

Because the path to marketing approval of any vaccine against COVID-19 is unclear, we may have a widely used vaccine in circulation in the United States or another country prior to our receipt of marketing approval. Unexpected safety issues, including any that we have not yet observed in our Phase 1/2 clinical trials for BNT162, could lead to significant reputational damage for BioNTech and our technology platforms going

26

forward and other issues, including delays in our other programs, the need for re-design of our clinical trials and the need for significant additional financial resources.

We also may be restricted or prohibited from marketing or manufacturing a BNT162 vaccine, even after obtaining product approval, if previously unknown problems with the product or its manufacture are subsequently discovered. We cannot provide assurance that newly discovered or developed safety issues will not arise following regulatory approval. With the use of any vaccine by a wide patient population, serious adverse events may occur from time to time that did not arise in the clinical trials of the product or that initially appeared to be unrelated to the vaccine itself and only with the collection of subsequent information were found to be causally related to the product. Any such safety issues could cause us to suspend or cease marketing of our approved products, possibly subject us to substantial liabilities, and adversely affect our ability to generate revenue and our financial condition.

We may be unable to produce a successful COVID-19 vaccine and establish a competitive market share for our vaccine before a competitor or before the COVID-19 outbreak is effectively contained or the risk of coronavirus infection is significantly diminished.

A large number of vaccine manufacturers, academic institutions and other organizations currently have programs to develop COVID-19 vaccine candidates. While we are not aware of all of our competitors’ efforts, we believe that the University of Oxford/AstraZeneca plc, CanSino Biologics Inc., Sanofi/GlaxoSmithKline plc Inovio Pharmaceuticals, Inc., China National Pharmaceutical Group (Sinopharm)/Beijing Institute of Biological Products and Wuhan Institute of Biological Products, Moderna, Inc., Johnson & Johnson, Novavax, Inc. and other companies are all in the early stages of developing vaccine candidates against COVID-19. Our competitors pursuing vaccine candidates may have greater financial, product candidate development, manufacturing and marketing resources than we do. Larger pharmaceutical and biotechnology companies have extensive experience in clinical testing and obtaining regulatory approval for their products, and may have the resources to heavily invest to accelerate discovery and development of their vaccine candidates.

Our efforts to develop BNT162 for regulatory approval and commercialization may fail if competitors develop and commercialize one or more COVID-19 vaccines before we are able to do so, or if they develop and commercialize one or more COVID-19 vaccines that are safer, more effective, produce longer immunity against COVID-19, require fewer administrations, have fewer or less severe side effects, have broader market acceptance, are more convenient or are less expensive than any vaccine candidate that we may develop.

Other companies or organizations may challenge our intellectual property rights or may assert intellectual property rights that prevent us from developing and commercializing our product candidates and other technologies.

We practice in new and evolving scientific fields, the continued development and potential use of which has resulted in many different patents and patent applications from organizations and individuals seeking to obtain intellectual property protection in the fields. We own and in-license patent applications and issued patents that describe and/or claim certain technologies, including products, reagents, formulations and methods including uses and manufacturing methods, or features or aspects of any of these. These issued patents and pending patent applications claim certain compositions of matter and methods relating to the discovery, development, manufacture and commercialization of therapeutic modalities and our delivery technologies, including LNPs. If we, our co-owners or our licensors are unable to obtain, maintain, protect, defend or enforce patent protection with respect to our product candidates and other technology and any product candidates and technology we develop, our business, financial condition, results of operations and prospects could be materially harmed.

As the scientific fields mature, our known competitors and other third parties have filed, and will continue to file, patent applications claiming inventions in the field in the United States and abroad. There is uncertainty about which patents will issue, and, if they do, as to when, to whom and with what claims. With respect to both

27

in-licensed and owned intellectual property, we cannot predict whether the patent applications we and our licensors are currently pursuing will issue as patents in any particular jurisdiction or whether the claims of any issued patents will provide sufficient protection from competitors.

We, our co-owners or our licensors may in the future become a party to patent proceedings or priority disputes in the United States, Europe or other jurisdictions. The Leahy-Smith America Invents Act, or the America Invents Act, enacted in September 2011, included a number of significant changes that affect the way patent applications will be prosecuted and also may affect patent litigation. These include allowing third-party submission of prior art to the USPTO during patent prosecution and additional procedures to attack the validity of a patent through USPTO-administered post-grant proceedings, including post-grant review, inter partes review and derivation proceedings. We expect that our competitors and other third parties will institute litigation and other proceedings, such as interference, reexamination and opposition proceedings, as well as inter partes and post-grant review proceedings against us and the patents and patent applications that we own and in-license. For example, various third parties have filed opposition papers challenging our issued EP patent 2714071 which relates to our iNeST product candidates, and whose claims recite steps relating to neoantigen selection.

We expect that we will be subject to similar proceedings or priority disputes, including oppositions, in Europe or other foreign jurisdictions relating to patents and patent applications in our portfolio.

If we, our co-owners or our licensors are unsuccessful in any interference proceedings or other priority or validity disputes, including any derivations, post-grant review, inter partes review or oppositions, to which we or they are subject, we may lose valuable intellectual property rights through the narrowing or loss of one or more patents owned or in-licensed, or our owned or in-licensed patent claims may be narrowed, invalidated or held unenforceable. In many cases, the possibility of appeal exists for either us or our opponents, and it may be years before final, unappealable rulings are made with respect to these patents in certain jurisdictions. The timing and outcome of these and other proceedings is uncertain and may adversely affect our business if we are not successful in defending the patentability and scope of our pending and issued patent claims. In addition, third parties may attempt to invalidate our intellectual property rights. Even if our rights are not directly challenged, disputes could lead to the weakening of our intellectual property rights. Our defense against any attempt by third parties to circumvent or invalidate our intellectual property rights could be costly to us, could require significant time and attention of our management and could have a material adverse impact on our business and our ability to successfully compete against our current and future competitors.

There are many issued and pending patent filings that claim aspects of technologies that we may need for our mRNA product candidates or other product candidates, including patent filings that relate to relevant delivery technologies. There are also many issued patents that claim targeting genes or portions of genes that may be relevant for immunotherapies we wish to develop. In addition, there may be issued and pending patent applications that may be asserted against us in a court proceeding or otherwise based upon the asserting party’s belief that we may need such patents for the development, manufacturing and commercialization of our product candidates. Thus, it is possible that one or more organizations, ranging from our competitors to non-practicing entities or patent assertion entities, has or will hold patent rights to which we may need a license, or hold patent rights which could be asserted against us. Such licenses may not be available on commercially reasonable terms or at all, or may be non-exclusive. If those organizations refuse to grant us a license to such patent rights on reasonable terms or a court rules that we need such patent rights that have been asserted against us and we are not able to obtain a license on reasonable terms or at all, we may be unable to perform research and development or other activities or market products covered by such patents, and we may need to cease the development, manufacture and commercialization of one or more of the product candidates we may develop. Any of the foregoing could result in a material adverse effect on our business, financial condition, results of operations or prospects.

Risks Related to Ownership of the ADSs and the Underwritten Offering

A significant portion of our total outstanding ordinary shares after the Underwritten Offering will be restricted from immediate resale but may be sold in the near future. The large number of shares eligible for sale or subject to rights requiring us to register them for sale could cause the market price of the ADSs to drop significantly, even if our business is performing well.

Sales of a substantial number of ordinary shares or the ADSs could occur at any time, subject to certain restrictions described below. These sales, or the perception in the market that holders of a large number of shares intend to sell shares, could reduce the market price of the ADSs. Based on the number of our ordinary shares outstanding as of July 21, 2020, we will have 237,673,455 ordinary shares outstanding after the Underwritten Offering. Additionally, if the Rights Offering is fully subscribed (excluding new ordinary shares underlying rights offered to holders that have irrevocably agreed not to transfer or exercise their rights), we will have 239,355,304 shares outstanding.

In connection with the Underwritten Offering, we, all of our directors and officers and certain significant shareholders have entered into lock-up agreements with the underwriters under which we and they agreed, subject to specific exceptions, not to sell any of our shares for at least 90 days following the date of this prospectus. The remaining ordinary shares will be available for sale after the Underwritten Offering since they are not subject to contractual and legal restrictions on resale. Any or all of the shares subject to lock-up agreements may be released prior to the expiration of the lock-up period at the discretion of the lead underwriters for the Underwritten Offering. To the extent shares are released before the expiration of the lock-up period and these shares are sold into the market, the market price of the ADSs could decline.

We intend to file one or more registration statements on Form S-8 under the Securities Act of 1933, as amended, or the Securities Act, to register all ordinary shares issued or issuable under our equity plans. Any such Form S-8 registration statements will automatically become effective upon filing. Accordingly, shares registered under such registration statements will be available for sale in the open market following the expiration of the applicable lock-up period. See “Shares and ADSs Eligible for Future Sale” appearing elsewhere in this prospectus for a more detailed description of the restrictions on selling shares.

Sales of ADSs or our ordinary shares as restrictions end or pursuant to registration rights may make it more difficult for us to finance our operations through the sale of equity securities in the future at a time and at a price that we deem appropriate. These sales also could cause the trading price of the ADSs to fall and make it more difficult for you to sell the ADSs.

If you purchase ADSs in the Underwritten Offering, you will incur immediate and substantial dilution in the book value of your investment.

You will suffer immediate and substantial dilution in the net tangible book value of the ADSs if you purchase ADSs in the Underwritten Offering. Based on an assumed public offering price of $85.25 per ADS, which was the last reported sale price of the ADSs on the Nasdaq Global Select Market on July 17, 2020, after giving effect to the Underwritten Offering, purchasers of ADSs in the Underwritten Offering will experience immediate dilution in net tangible book value of $80.79 per ADS. In addition, after giving effect to the Underwritten Offering, investors purchasing ADSs in the Underwritten Offering will contribute 24.77% of the total amount invested by shareholders since inception but will only own 2.10% of the ordinary shares outstanding. See “Dilution” for a more detailed description of the dilution to new investors in the Underwritten Offering.

29

Holders of the ADSs may not be able to participate in any future preemptive subscription rights issues or elect to receive dividends in shares, which may cause additional dilution to their holdings. For example, purchasers who acquire ADSs in the Underwritten Offering will not receive rights to participate in the concurrent Rights Offering.

Under German law, the existing shareholders of a company generally have a preemptive right in proportion to the amount of shares they hold in connection with any issuance of ordinary shares, convertible bonds, bonds with warrants, profit participation rights and participating bonds. However, our shareholders in a shareholders’ meeting may vote, by a majority representing at least three-quarters of the share capital represented at the meeting, to waive this preemptive right provided that, from the company’s perspective, there exists good and objective cause for such waiver.

The deposit agreement provides that the depositary need not make rights available to you unless the distribution to ADS holders of both the rights and any related securities are either registered under the Securities Act or exempted from registration under the Securities Act. We are under no obligation to file a registration statement with respect to any such rights or securities or to endeavor to cause such a registration statement to be declared effective. Moreover, we may not be able to establish an exemption from registration under the Securities Act. Accordingly, ADS holders may be unable to participate in our future rights offerings and may experience dilution in their holdings. In addition, if the depositary is unable to sell rights that are not exercised or not distributed or if the sale is not lawful or reasonably practicable, it will allow the rights to lapse, in which case you will receive no value for these rights. Purchasers who acquire ADSs in the Underwritten Offering will not receive rights to participate in the concurrent Rights Offering.

Our principal shareholders and management own a significant percentage of our ordinary shares and will be able to exert significant control over matters subject to shareholder approval.

Our executive officers, directors, five percent shareholders, and their affiliates beneficially own approximately 69.99% of our ordinary shares (including ordinary shares represented by ADSs) and, upon closing of the Underwritten Offering, that same group will beneficially own approximately           % of our outstanding ordinary shares (including ordinary shares represented by ADSs), assuming no exercise of the underwriters’ option to purchase additional ADSs from the Selling Shareholder. If the underwriters exercise in full their option to purchase additional ADSs from the Selling Shareholder, that same group will beneficially own approximately           % of our outstanding ordinary shares (including ordinary shares represented by ADSs). Therefore, even after the Underwritten Offering, these shareholders will have the ability to influence us through their ownership positions. For example, these shareholders, acting together, may be able to exert significant influence over matters such as elections of directors, amendments of our organizational documents, or approval of any merger, sale of assets or other major corporate transaction. This may prevent or discourage unsolicited acquisition proposals or offers for our ordinary shares that you may believe are in your best interest as one of our shareholders.

We have broad discretion in the use of our cash, cash equivalents and investments, including the net proceeds from the Underwritten Offering, and we may not use them effectively.

Our management will have broad discretion in the application of our cash, cash equivalents and investments, including the net proceeds from the Global Offering, and could spend the proceeds in ways that do not improve our results of operations or enhance the value of our ordinary shares. The failure by our management to apply these funds effectively could result in financial losses that could have a material adverse impact on our business, cause the price of the ADSs to decline, and delay the development of our product candidates. Pending their use, we may invest our cash, cash equivalents and investments, including the net proceeds from the Global Offering, in a manner that does not produce income or that loses value. See “Use of Proceeds” for more information.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus contains forward-looking statements concerning our business, operations and financial performance and condition, as well as our plans, objectives and expectations for our business operations and financial performance and condition. Many of the forward-looking statements contained in this prospectus can be identified by the use of forward-looking words such as “anticipate,” “believe,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “potential,” “should,” “target,” “would” and other similar expressions that are predictions of or indicate future events and future trends, although not all forward-looking statements contain these identifying words.

Forward-looking statements are based on our management’s beliefs and assumptions and on information currently available to our management. Such statements are subject to risks and uncertainties, and actual results may differ materially from those expressed or implied in the forward-looking statements due to a variety of factors, including, but not limited to, those identified in the section titled “Risk Factors” in this prospectus and in our Annual Report on Form 20-F for the year ended December 31, 2019, incorporated by reference herein. These risks and uncertainties include factors relating to:

31

The preceding list is not intended to be an exhaustive list of all of our forward-looking statements. The forward-looking statements contained in this prospectus speak only as of the date of this prospectus, and unless otherwise required by law, we do not undertake any obligation to update them in light of new information or future developments or to release publicly any revisions to these statements in order to reflect later events or circumstances or to reflect the occurrence of unanticipated events.

32

USE OF PROCEEDS

We estimate that the net proceeds to us from the Underwritten Offering will be approximately $400.7 million (€360.7 million), assuming a public offering price of $85.25 per ADS, which was the last reported sale price of the ADSs on the Nasdaq Global Select Market on July 17, 2020, and after deducting underwriting discounts and commissions and estimated offering expenses payable by us. We will not receive any proceeds from the potential sale of ADSs in this Underwritten Offering by the Selling Shareholder, pursuant to the underwriters’ option to purchase additional ADSs from the Selling Shareholder.

Each $1.00 increase (decrease) in the assumed public offering price of $85.25 per ADS, which was the last reported sale price of the ADSs representing our ordinary shares on the Nasdaq Global Select Market on July 17, 2020, would increase (decrease) the net proceeds to us from the Underwritten Offering by approximately $4.8 million ($4.8 million), assuming the number of ADSs offered by us, as set forth on the cover page of this prospectus, remains the same, and after deducting underwriting discounts and commissions and estimated offering expenses payable by us.

If the Rights Offering to be commenced following the setting of the price to public for the Underwritten Offering, as part of the Global Offering, is fully subscribed (excluding ordinary shares underlying rights offered to holders that have irrevocably agreed not to transfer or exercise their rights), we estimate that the additional net proceeds to us in the Global Offering will be approximately $136.2 million (€122.6 million), assuming a subscription price of $85.25 per ordinary share or ADS, which was the last reported sale price of the ADSs on the Nasdaq Global Select Market on July 17, 2020, and after deducting fees and estimated offering expenses payable by us.

We may also increase or decrease the number of ADSs we are offering in the Underwritten Offering, which would affect the number of our ordinary shares and ADSs representing our ordinary shares underlying rights granted in the Rights Offering. An increase (decrease) of 1,000,000 in the number of ADSs offered by us would further increase (decrease) the net proceeds to us from the Global Offering by approximately €91.3 million, assuming no change in the assumed public offering price, after deducting underwriting discounts and commissions and estimated offering expenses payable by us and after giving effect to a proportionate increase (decrease) in the number of ordinary shares and ADSs representing our ordinary shares underlying rights granted in the Rights Offering, assuming the Rights Offering is fully subscribed (excluding ordinary shares underlying rights offered to holders that have irrevocably agreed not to transfer or exercise their rights).

We currently intend to use the net proceeds from the Global Offering to:

33

We expect to use the remainder of any net proceeds from the Global Offering, as well as our existing cash and cash equivalents, for general corporate purposes. We may also use a portion of the net proceeds to in-license or acquire or invest in complementary technologies, products, businesses or assets, either alone or together with a collaborator. However, we have no current plans, commitments or obligations to do so.

Our expected use of net proceeds from the Global Offering represents our current intentions based on our present plans and business condition, which could change as our plans and business conditions evolve. The amounts and timing of our actual use of net proceeds will vary depending on numerous factors, including the progress of our clinical development of our product candidates, including our ongoing clinical trials. As a result, we cannot predict with certainty all of the particular uses for the net proceeds to be received upon the closings of

the Global Offering or the amounts that we will actually spend on the uses set forth above. Our management will have broad discretion in the application of the net proceeds from the Global Offering.

We expect that we will need to raise significant additional funds beyond the Global Offering in order to continue to advance our pipeline. In particular, we will need additional funds in order to advance our product candidates through Phase 3 clinical trials and to potential commercialization. We may seek to raise capital through public or private equity or debt financing, government or other third-party grants or funding, sales of assets, marketing and distribution arrangements, other collaborations or a combination of these approaches.

Based on our planned use of the net proceeds of the Global Offering and our existing cash and cash equivalents, we estimate that such funds will be sufficient to enable us to fund our operating expenses and capital expenditure requirements through at least the next 18 months. We have based this estimate on assumptions that may prove to be incorrect, and we could use our available capital resources sooner than we currently expect.

Pending our use of the net proceeds from the Global Offering, we plan to invest the net proceeds in short- and intermediate-term interest-bearing financial instruments.

34

DIVIDEND POLICY

We have never paid or declared any cash dividends on our ordinary shares, and we do not anticipate paying any cash dividends on our ordinary shares in the foreseeable future. We intend to retain all available funds and any future earnings to fund the development and expansion of our business. In addition, our ability to pay cash dividends is also limited in certain circumstances under the terms of an agreement we have entered into with the Bill & Melinda Gates Foundation. All of the shares represented by the ADSs offered by this prospectus will generally have the same dividend rights as all of our other outstanding shares.

Under German law, we may pay dividends only from the distributable profit (Bilanzgewinn) reflected in our unconsolidated financial statements (as opposed to the consolidated financial statements for us and our subsidiaries) prepared in accordance with the principles set forth in the German Commercial Code (Handelsgesetzbuch) and adopted by our management board (Vorstand) and the supervisory board (Aufsichtsrat), or, as the case may be, by our shareholders in a shareholders’ meeting. See “Description of Share Capital and Articles of Association (Satzung),” which explains in more detail the procedures we must follow and the German law provisions that determine whether we are entitled to declare a dividend.

35

CAPITALIZATION

The table below sets forth our cash and cash equivalents and our total capitalization as of March 31, 2020:

The table below does not reflect the effects of the issuance of the 2,595,996 ordinary shares and a mandatory convertible note to be issued in the June 2020 Private Placement, which is expected to close in August 2020, and our receipt of proceeds of €223.9 million ($251.0 million, translated using the exchange rate then in effect as published by the German Central Bank (Deutsche Bundesbank)) therefrom.

Our capitalization following the Underwritten Offering will be adjusted based on the actual public offering price and other terms of the Underwritten Offering determined at pricing, including the amount by which actual offering expenses are higher or lower than estimated. You should read this table in conjunction with our consolidated financial statements and related notes included in this prospectus as well as the sections in this prospectus titled “Use of Proceeds” and “Selected Consolidated Financial Data” and the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Forms 20-F and 6-K incorporated by reference herein.

36

The number of our ordinary shares issued and outstanding actual is based on 232,304,250 ordinary shares outstanding (including 5,524,506 shares held in treasury) as of March 31, 2020 and excludes:

37

DILUTION

If you invest in the ADSs in the Underwritten Offering, your interest will be diluted immediately to the extent of the difference between the public offering price per ADS and our as adjusted net tangible book value per ADS after completion of the Underwritten Offering. The discussion in this section does not reflect the effects of the issuance of the 2,595,996 ordinary shares and a mandatory convertible note to be issued in the June 2020 Private Placement, which is expected to close in August 2020, and our receipt of proceeds of €223.9 million ($251.0 million, translated using the exchange rate then in effect as published by the German Central Bank (Deutsche Bundesbank)) therefrom.

Net tangible book value per ADS represents the amount of our total assets less our total liabilities, excluding intangible assets, divided by the number of our ordinary shares outstanding as of March 31, 2020. As of March 31, 2020, we had a historical net tangible book value of €354.2 million ($393.4 million), corresponding to a net tangible book value per ordinary share of €1.56 ($1.73) (equivalent to $1.73 per ADS). Our pro forma net tangible book value as of March 31, 2020 was €593.2 million ($658.9 million), corresponding to a pro forma net tangible book value per ordinary share of €2.55 ($2.83) (equivalent to $2.83 per ADS), based on the total number of shares of our common stock outstanding as of March 31, 2020, and after giving effect to (i) the issuance of 1,935,488 ADSs representing our ordinary shares in connection with our acquisition of Neon, (ii) the issuance of 1,580,777 of our ordinary shares in a private placement to Fosun Pharma for proceeds of €45.6 million ($50.0 million, using the exchange rate then in effect as published by the German Central Bank (Deutsche Bundesbank)) and (iii) the issuance of 2,377,446 of our ordinary shares in a private placement to Pfizer for proceeds of €103.9 million ($113.0 million, using the exchange rate then in effect as published by the German Central Bank (Deutsche Bundesbank)).

After giving effect to the issuance and sale of 5,000,000 ADSs in the Underwritten Offering at an assumed public offering price of $85.25 per ADS, which was the last reported sale price of the ADSs on the Nasdaq Global Select Market on July 17, 2020, and after deducting underwriting discounts and commissions and estimated offering expenses payable by us, our pro forma as adjusted net tangible book value as of March 31, 2020 would have been €954.0 million ($1,059.6 million), corresponding to a net tangible book value per ordinary share of €4.02 ($4.46) (equivalent to $4.46 per ADS). This represents an immediate increase in net tangible book value of €1.47 ($1.63) per ordinary share (equivalent to $1.63 per ADS) to existing shareholders and immediate dilution of $80.79 per ADS to new investors purchasing ADSs in the Underwritten Offering. Dilution per ADS to new investors is determined by subtracting our pro forma as adjusted net tangible book value per ADS from the assumed public offering price per ADS paid by new investors.

The following table illustrates this dilution on a per-ADS basis:

Each $1.00 increase (decrease) in the assumed public offering price of $85.25 per ADS, which was the last reported sale price of the ADSs on the Nasdaq Global Select Market on July 17, 2020, would increase (decrease) our pro forma as adjusted net tangible book value as of March 31, 2020 by $0.02 ($0.02) per ADS, and would

38

increase (decrease) dilution to new investors in the Underwritten Offering by $0.02 ($0.02) per ADS, assuming that the number of ADSs offered by us, as set forth on the cover page of this prospectus, remains the same, and after deducting underwriting discounts and commissions and estimated offering expenses payable by us. In addition, if the Rights Offering is fully subscribed (excluding ordinary shares underlying rights offered to holders that have irrevocably agreed not to transfer or exercise their rights), our pro forma as adjusted net tangible book value per ADS would be $5.00, representing an immediate increase in pro forma as adjusted net tangible book value to existing shareholders of $2.17 per ADS and immediate dilution of $80.25 per ADS to new investors, after deducting underwriting discounts and commissions, fees and estimated offering expenses payable by us. We may also increase or decrease the number of ADSs we are offering in the Underwritten Offering, which would affect the number of our ordinary shares and ADSs representing our ordinary shares underlying rights granted in the Rights Offering. An increase (decrease) of 1,000,000 in the number of ADSs offered by us would further increase (decrease) our pro forma as adjusted net tangible book value as of March 31, 2020 by $0.39 ($0.40) per ADS, and would decrease (increase) dilution to new investors in the Underwritten Offering by $0.39 ($0.40) per ADS, assuming no change in the assumed public offering price, after deducting underwriting discounts and commissions and estimated offering expenses payable by us and after giving effect to a proportionate increase (decrease) in the number of ordinary shares and ADSs representing our ordinary shares underlying rights granted in the Rights Offering, assuming the Rights Offering is fully subscribed (excluding ordinary shares underlying rights offered to holders that have irrevocably agreed not to transfer or exercise their rights).

The pro forma as adjusted information is illustrative only, and we will adjust this information based on the actual public offering price and other terms of the Global Offering determined at pricing.

The following table sets forth, on a pro forma as adjusted basis as of March 31, 2020, after giving effect to (i) the issuance of 1,935,488 ADSs representing our ordinary shares in connection with our acquisition of Neon, (ii) the issuance of 1,580,777 of our ordinary shares in a private placement to Fosun Pharma for proceeds of €45.6 million ($50.0 million, using the exchange rate then in effect as published by the German Central Bank (Deutsche Bundesbank)) and (iii) the issuance of 2,377,446 of our ordinary shares in a private placement to Pfizer for proceeds of €103.9 million ($113.0 million, using the exchange rate then in effect as published by the German Central Bank (Deutsche Bundesbank)), the number of ordinary shares owned by existing shareholders and to be owned by new investors purchasing ADSs in the Underwritten Offering, the total consideration paid by existing shareholders and new investors purchasing ADSs in the Underwritten Offering, the average price per ordinary share paid by our existing shareholders and the average price per ADS to be paid by new investors purchasing ADSs in the Underwritten Offering. The calculation below is based on an assumed public offering price of $85.25 per ADS, which was the last reported sale price on the Nasdaq Global Select Market on July 17, 2020, before deducting underwriting discounts and commissions and estimated offering expenses payable by us:

Each $1.00 increase (decrease) in the assumed public offering price of $85.25 per ADS, which was the last reported sale price of the ADSs on the Nasdaq Global Select Market on July 17, 2020, would increase (decrease) the total consideration paid by new investors by $5.0 million and increase (decrease) the percentage of total consideration paid by new investors by approximately 0.22% (0.22%), assuming that the number of ADSs offered by us, as set forth on the cover page of this prospectus, remains the same, and before deducting underwriting discounts and commissions and estimated offering expenses payable by us. We may also increase or decrease the number of ADSs we are offering in the Underwritten Offering, which would affect the number of our ordinary shares and ADSs representing our ordinary shares underlying rights granted in the Rights Offering.

39

An increase (decrease) of 1,000,000 in the number of ADSs offered by us would increase (decrease) the total consideration paid by investors participating in this offering by $106.7 million ($106.7 million), and increase (decrease) the percentage of total consideration paid by new investors by 4.39% (4.97%), assuming no change in the assumed public offering price and before deducting underwriting discounts and commissions and estimated offering expenses payable by us and after giving effect to a proportionate increase (decrease) in the number of ordinary shares and ADSs representing our ordinary shares underlying rights granted in the Rights Offering, assuming the Rights Offering is fully subscribed (excluding ordinary shares underlying rights offered to holders that have irrevocably agreed not to transfer or exercise their rights).

The number of our ordinary shares issued and outstanding actual, is based on 226,779,744 ordinary shares outstanding as of March 31, 2020 and excludes:

We may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of such securities may result in further dilution to our shareholders.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

On May 6, 2020, BioNTech SE, or BioNTech, announced the closing of the Neon Therapeutics, Inc., or Neon, acquisition. The merger agreement was first announced on January 16, 2020. Based on the acquisition date share price, the implied aggregate value of the merger consideration was approximately $97.1 million (€89.9 million using the exchange rate as of closing) financed by issuing new ordinary shares as a stock transaction and including de minimis cash consideration which was paid to settle Neon’s outstanding stock options.

The following unaudited pro forma condensed combined financial information are based on BioNTech’s historical consolidated financial statements prepared in accordance with International Financial Reporting Standards as issued by the IASB, or IFRS, and Neon’s historical consolidated financial statements as adjusted to give effect to our acquisition of Neon. As Neon prepared its financial statements in accordance with U.S. generally accepted accounting principles, or U.S. GAAP, and applied U.S. dollars as its reporting currency, adjustments have been made to convert Neon’s financial statements to IFRS and its reporting currency to Euros. Please see Notes 2 and 3 to the unaudited pro forma condensed combined financial information for a discussion of the adjustments made to convert Neon’s financial information from U.S. GAAP to IFRS.

The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2019 and the three months ended March 31, 2020 gives effect to this transaction as if it had occurred on January 1, 2019. The unaudited pro forma condensed combined statement of financial position as of March 31, 2020 gives effect to this transaction as if it had occurred on March 31, 2020.

The unaudited pro forma condensed combined financial information includes the latest estimates of the fair value of Neon’s assets to be acquired and liabilities to be assumed and the related allocations of the purchase price using the factual circumstances as of the time of closing. These figures are applied to the unaudited condensed combined statement of financial position as of March 31, 2020. As the detailed valuation studies are still ongoing, these estimates and assumptions are subject to change.

As indicated in Note 5 to the unaudited pro forma condensed combined financial information, BioNTech has made certain adjustments to adjust the historical book values of the assets and liabilities of Neon to reflect preliminary estimates of the fair values necessary to prepare the unaudited pro forma condensed combined financial information, with the excess of the estimated purchase price over the net assets of Neon, as adjusted to reflect estimated fair values, recorded as goodwill.

Additionally, as indicated in Note 2 to the unaudited pro forma condensed combined financial information, estimated effects related to the application of IFRS have been based on preliminary assessments and as indicated in Note 3 to the unaudited pro forma condensed combined financial information, the reporting currency has been applied based on a simplified method. Actual results are expected to differ from this unaudited pro forma condensed combined financial information once BioNTech has completed the valuation studies necessary to finalize the required purchase price allocation and finalized conforming accounting changes for Neon. Such differences may be material.

The assumptions and estimates underlying the unaudited adjustments to the pro forma condensed combined financial information are described in the accompanying notes, which should be read together with the pro forma condensed combined financial information.
