These readouts reinforce the potential of our platform technologies including our individualized and off-the-shelf mRNA vaccine platforms, iNeST and FixVac. We have also advanced our strategy by initiating clinical trials evaluating novel combinations of synergistic drug candidates. Notably, we dosed the first patient in a trial evaluating the combination of the TROP2 antibody-drug conjugate BNT325/DB-1305 and the PD-L1-VEGF-A bispecific BNT327/PM8002, aiming to harness the potent anti-tumor activity of antibody drug conjugates along with the sustained benefit of immunomodulators,” said Prof. Ugur Sahin, M.D., CEO and Co-Founder of BioNTech. “In addition, we have started commercializing variant-adapted COVID-19 vaccines for the upcoming season, while accelerating our clinical development efforts to realize the full potential of our technologies. We are making progress towards our goal of becoming a company with marketed medicines for cancer and infectious diseases.” Financial Review for Second Quarter and First Half of 2024 in millions €, except per share data Second Quarter 2024 Second Quarter 2023 First Half 2024 First Half 2023Revenues 128.7 167.7 316.3 1,444.7Net Profit / (Loss) (807.8) (190.4) (1,122.9) 311.8(Loss) / Diluted Earnings per Share (3.36) (0.79) (4.67) 1.28 Revenues reported were €128.7 million for the three months ended June 30, 2024, compared to €167.7 million for the comparative prior year period. For the six months ended June 30, 2024, revenues were €316.3 million, compared to €1,444.7 million for the comparative prior year period. The year-over-year change was mainly due to lower revenues from the sales of the Company’s COVID-19 vaccines worldwide resulting from the continued shift in demand from a pandemic to a seasonal endemic COVID-19 vaccine market. Cost of sales were €59.8 million for the three months ended June 30, 2024, compared to €162.9 million for the comparative prior year period. For the six months ended June 30, 2024, cost of sales were €118.9 million, compared to €258.9 million for the comparative prior year period. The change was mainly due to COVID-19 vaccine production in line with demand. Research and development (“R&D”) expenses were €584.6 million for the three months ended June 30, 2024, compared to €373.4 million for the comparative prior year period. For the six months ended June 30, 2024, R&D expenses were €1,092.1 million, compared to €707.4 million for the comparative prior year period. R&D expenses were mainly influenced by progressing clinical studies for the Company’s late-stage oncology pipeline candidates. Further contributions to the increase came from wages, benefits and social security expenses resulting from an increase in headcount. Sales, general and administrative (“SG&A”) expenses2, in total, amounted to €183.8 million for the three months ended June 30, 2024, compared to €137.9 million for the comparative prior year period. For the six months ended June 30, 2024, SG&A expenses were €316.4 million, compared to €261.9 million for the comparative prior year period. SG&A expenses were primarily driven by increased expenses for IT environment and wages, benefits, and social security expenses resulting from an increase in headcount. Other operating result amounted to €266.7 million negative operating result during the three months ended June 30, 2024, compared to €56.8 million negative operating result for the comparative prior year period. For the six months ended June 30, 2023, other operating result amounted to €262.3 million negative operating result compared with €125.4 million negative operating result for the prior year period. This change was primarily due to the recording of a provision related to a contractual dispute. Income taxes were accrued with an amount of €2.0 million of tax expenses for the three months ended June 30, 2024, compared to €221.8 million of realized tax income for the comparative prior year period. For the six months ended June 30, 2024, income taxes were realized with an amount of €14.7 million of tax income for the six months ended June 30, 2024, compared to €16.3 million of realized tax income for the comparative prior year period. The effective income tax rate for the six months ended June 30, 2024, was approximately 1.3%. Net loss was €807.8 million for the three months ended June 30, 2024, compared to €190.4 million loss for the comparative prior year period. For the six months ended June 30, 2024, loss was €1,122.9 million for the six months ended June 30, 2024, compared to a profit of €311.8 million for the comparative prior year period. Cash and cash equivalents plus security investments as of June 30, 2024, reached €18,485.1 million, comprising €10,376.7 million cash and cash equivalents, €6,916.7 million current security investments and €1,191.7 million non-current security investments. This position increased during the second quarter of 2024 largely attributable to a cash payment received from BioNTech’s collaboration partner Pfizer Inc. (“Pfizer”). Loss per share was €3.36 for the three months ended June 30, 2024, compared to €0.79 for the comparative prior year period. For the six months ended June 30, 2024, loss per share was €4.67, compared to diluted earnings per share of €1.28 for the comparative prior year period. Shares outstanding as of June 30, 2024 were 237,766,235, excluding 10,785,965 shares held in treasury. “Our second quarter revenues correspond to the current demand of a seasonal endemic COVID-19 vaccine market,” said Jens Holstein, CFO of BioNTech. “Supported by our strong financial position, we will continue to focus on our long-term growth strategy throughout the remainder of the year. This includes our clinical pipeline for individualized therapies, the build-out of our manufacturing capacities and capabilities to support additional late-stage trials as well as our commercialization activities. These investments build the foundation for the next stage of growth and the transformation of BioNTech into a multi-product company.” 2024 Financial Year Guidance3 Reiterated The Company reiterates its prior outlook for the financial year: Total revenues for the 2024 financial year €2.5 billion - €3.1 billion BioNTech expects revenues for the full 2024 financial year to be in the range of €2.5 to €3.1 billion. The range reflects certain assumptions and expectations, including, but not limited to: the timing and granting of regulatory approvals and recommendations; COVID-19 vaccine uptake and price levels; inventory write-downs by BioNTech’s collaboration partner Pfizer that would negatively influence BioNTech’s revenues; seasonal variations in SARS-CoV-2 circulation and vaccination uptake, which are expected to lead to demand peaks in the autumn and winter compared to other seasons; and revenues from a pandemic preparedness contract with the German government as well as revenues from the BioNTech Group service businesses, namely InstaDeep Ltd., JPT Peptide Technologies GmbH, and in Idar-Oberstein at BioNTech Innovative Manufacturing Services GmbH. Generally, the Company continues to remain largely dependent on revenues generated in its collaboration partner’s territories in 2024. Planned 2024 Financial Year Expenses and Capex: R&D expenses4 €2.4 billion - €2.6 billion SG&A expenses €700 million - €800 million Capital expenditures for operating activities €400 million - €500 million The full interim unaudited condensed consolidated financial statements can be found in BioNTech’s Report on Form 6-K for the period ended June 30, 2024, filed today with the United States Securities and Exchange Commission (“SEC”) and available at https://www.sec.gov/.

It does not include potential payments resulting from the outcomes of ongoing and/or future legal disputes or related activity, such as judgements or settlements, which may have a material effect on the Company’s results of operations and/or cash flows. BioNTech continues to expect to report a loss for the 2024 financial year and expects to recognize the vast majority of its full year revenues mostly in the fourth quarter. 4 Numbers include effects identified from additional collaborations or potential M&A transactions to the extent disclosed and are subject to update due to future developments. Operational Review of the Second Quarter 2024, Key Post Period-End Events and Outlook Variant-adapted Monovalent COVID-19 Vaccines (COMIRNATY®) In April 2024, the World Health Organization (“WHO”), the European Medicines Agency (“EMA”) and, subsequently, other health authorities, provided guidance highlighting that updated vaccines targeting Omicron JN.1 or JN.1 sublineages may contribute to maintaining protection against COVID-19 during the upcoming fall and winter seasons. On June 27, 2024, BioNTech and Pfizer announced that the Committee for Medicinal Products for Human Use (“CHMP”) of the EMA recommended marketing authorization for the companies’ Omicron JN.1-adapted monovalent COVID-19 vaccine (COMIRNATY® JN.1) for active immunization to prevent COVID-19 caused by SARS-CoV-2 in individuals six months of age and older. On July 3, 2024, the European Commission (“EC”) adopted a decision following the CHMP’s recommendation. Shortly following the EC decision, the updated vaccine was made available to ship to EU member states.On June 6, 2024, the U.S. FDA’s Vaccines and Related Biological Products Advisory Committee (“VRBPAC”) issued guidance recommending the manufacturing of a JN.1-adapted monovalent COVID-19 vaccine for the 2024/2025 fall and winter seasons. On June 13, 2024, the U.S. FDA announced the KP.2 strain as the preferred JN.1-lineage for COVID-19 vaccines (2024-2025 Formula). In June 2024, BioNTech and Pfizer submitted regulatory applications to the U.S. FDA for the companies’ Omicron JN.1-adapted monovalent vaccine, and initiated a rolling sBLA for an Omicron KP.2-adapted monovalent vaccine. The companies plan to prepare shipments in the United States of KP.2-adapted monovalent COVID-19 vaccines for fast delivery following potential regulatory approval, currently expected in September 2024.On July 24, 2024, the United Kingdom’s Medicines and Healthcare products Regulatory Agency (“MHRA”) approved the companies’ Omicron JN.1-adapted vaccine. COVID-19 – Influenza Combination Vaccine Program BNT162b2 + BNT161 is an mRNA-based combination vaccine program against COVID-19 and influenza being developed in collaboration with Pfizer. Top-line data from the Phase 1/2 trial (NCT05596734) demonstrated robust immune responses to influenza A, influenza B, and SARS-CoV-2 strains and that the safety profile of the candidates was consistent with the profile of the companies’ COVID-19 vaccine. A Phase 3 clinical trial (NCT06178991) is fully enrolled and data are expected later this year. Select Oncology Pipeline Highlights Cancer Vaccine Programs BNT111 is based on BioNTech’s FixVac platform, and is a wholly owned, systemically administered, off-the-shelf uridine mRNA-lipoplex based cancer vaccine candidate encoding shared melanoma associated antigens. A randomized Phase 2 clinical trial (NCT04526899) being conducted in collaboration with Regeneron Pharmaceuticals Inc. (“Regeneron”) is ongoing to evaluate BNT111 in combination with cemiplimab, BNT111 alone, or cemiplimab alone in anti-PD-1-/anti-PD-L1 refractory/relapsed, unresectable stage III or IV melanoma.In July 2024, BioNTech announced that the study met its primary efficacy outcome measure, demonstrating a statistically significant improvement in overall response rate (“ORR”) in patients treated with BNT111 in combination with the anti-PD-1 checkpoint inhibitor, cemiplimab, as compared to a historical control in this indication and treatment setting. The ORR in the cemiplimab monotherapy arm was in line with the historical control of anti-PD-L1 or anti-CTLA-4 treatments in this patient group. The treatment was well tolerated and the safety profile of BNT111 in combination with cemiplimab in this trial was consistent with previous clinical trials assessing BNT111 in combination with anti-PD-L1-containing treatments. The Phase 2 trial will continue as planned to further assess the secondary endpoints which were not mature at the time of the primary analysis.BioNTech plans to present data from this trial at an upcoming medical conference. BNT113 is a cancer vaccine candidate based on FixVac’s platform encoding for shared antigens associated with Human Papilloma Virus (“HPV16+”) head and neck cancer. A global, randomized Phase 2 clinical trial (NCT04534205) evaluating BNT113 in combination with pembrolizumab versus pembrolizumab monotherapy as a first-line treatment in patients with unresectable recurrent or metastatic HPV16+ head and neck squamous cell carcinoma expressing PD-L1 is ongoing. Data updates are expected to be presented at the 2024 Congress of the European Society of Medical Oncology (“ESMO”) taking place from September 13-17, 2024 in Barcelona, Spain.

Ottensmeier Autogene cevumeran (BNT122) is a uridine mRNA-lipoplex based cancer vaccine candidate for individualized neoantigen-specific immunotherapy (“iNeST”) being developed in collaboration with Genentech, Inc. (“Genentech”), a member of the Roche Group (“Roche”). Autogene cevumeran is being evaluated in ongoing Phase 2 trials in adjuvant resected pancreatic ductal adenocarcinoma (“PDAC”) (NCT05968326), first-line melanoma (NCT03815058) and adjuvant colorectal cancer (“CRC”) (NCT04486378). A Phase 2 clinical trial in an additional indication is planned.In June 2024, epidemiologic data were presented at the American Society of Clinical Oncology (“ASCO”) Annual Meeting, including data on post-operative circulating tumor DNA (“ctDNA”) prevalence and prognostic value in disease-free survival, from an observational study (NCT04813627) in patients with resected high-risk stage II/III CRC. These epidemiological and prognostic data are supportive of the ongoing interventional Phase 2 clinical trial (NCT04486378).Also in June 2024, at the 2024 European Society for Medical Oncology Gastrointestinal Cancers (“ESMO-GI”) Congress, immunogenicity data were presented from the biomarker cohort of the ongoing Phase 2 (NCT04486378) that enrolled patients irrespective of post-surgical ctDNA status. The data indicate that autogene cevumeran is highly immunogenic and induces de novo polyepitopic, ex vivo detectable T-cell responses in all evaluable patients with resected​ stage II (high risk) or III CRC after completion of adjuvant chemotherapy.​ Among patients included in the immunogenicity analysis, all (12/12) were disease-free at data cut off.Preliminary data from the ongoing Phase 2 clinical trial (NCT04486378) in stage II (high risk) and III ctDNA+ adjuvant CRC is expected in late 2025 or 2026. Next-Generation Immune Checkpoint Immunomodulator Programs BNT327/PM8002 is a bispecific antibody candidate combining PD-L1 checkpoint inhibition with VEGF-A neutralization and is being developed in collaboration with Biotheus Inc. (“Biotheus”). BNT327/PM8002 is currently being evaluated in multiple Phase 2 and Phase 3 clinical trials in China to assess the efficacy and safety of the candidate as monotherapy or in combination with chemotherapy in various indications.In June 2024, at the 2024 ASCO Annual Meeting, monotherapy data were presented from an ongoing Phase 1/2 clinical trial (NCT05918445) for cohorts of patients with advanced cervical cancer (“CC”), platinum-resistant recurrent ovarian cancer (“PROC”), and advanced non-small cell lung cancer (“NSCLC”). Data on 48 patients with advanced CC showed an ORR of 42.2% (52.4% in patients with PD-L1-positive tumors), a disease control rate (“DCR”) of 93.3%, and a median progression-free survival (“mPFS”) of 8.3 months. Data on 39 patients with PROC showed an ORR of 20.6%, a DCR of 67.7%, and a mPFS of 5.5 months. Treatment related adverse events (“TRAEs”) occurred in 95.4% of patients (83/87) with ≥ Grade 3 TRAEs in 36.8% (32/87) and 14.9% (13/87) of patients discontinued BNT327/PM8002 treatment due to TRAEs. Median follow-up time in patients with CC and PROC was 13.8 months and 14.8 months, respectively. Data on 61 patients with non-squamous NSCLC were also presented. Data on 17 evaluable patients with untreated NSCLC wild-type and PD-L1-positive showed an ORR of 47.1%, a DCR of 100% and a mPFS of 13.6 months at a median follow-up of 11.3 months. Data on 36 evaluable patients with epidermal growth factor receptor (“EGFR”)-mutant NSCLC after progression on prior EGFR-tyrosine kinase inhibitor treatment showed an ORR of 19.4%, a DCR of 69.4% and a mPFS of 5.5 months at a median follow-up of 12.6 months. Data from 8 evaluable patients with EGFR/anaplastic lymphoma kinase (“ALK”) wild-type NSCLC that progressed after anti-PD-1/L1 therapy and platinum-based chemotherapy showed an ORR of 12.5%, a DCR of 62.5%, and a mPFS of 5.8 months at a median follow-up of 5.8 months. TRAEs occurred in 85.2% of patients (52/61) with ≥Grade 3 TRAEs in 19.7% (12/61), serious adverse events were observed in 24.6% (15/61) of patients, 8.2% (5/61) of patients discontinued BNT327/PM8002 treatment due to TRAEs. In June 2024, the first patient was dosed in the Phase 1/2 clinical trial (NCT05438329) evaluating the combination of BNT327/PM8002 with BNT325/DB-1305, an antibody-drug conjugate (“ADC”) candidate targeting TROP-2. Additional trials with novel BNT327 and other ADC combinations are planned to begin this year.Two Phase 2 dose optimization studies are expected to start soon. A Phase 2 clinical trial (NCT06449222) to evaluate the safety, efficacy, and pharmacokinetics of BNT327/PM8002 at two dose levels in combination with chemotherapy in the first- and second-line treatment of patients with locally advanced/metastatic triple negative breast cancer (“TNBC”).A Phase 2 clinical trial (NCT06449209) to evaluate BNT327/PM8002 in combination with chemotherapy in patients with untreated extended-stage small-cell lung cancer (“ES-SCLC”) or small-cell lung cancer (“SCLC”) progressed on first- or second-line treatment.Data from these studies are expected as early as 2025.

Paz-Ares While the emerging clinical profile of BNT311/GEN1046 (acasunlimab) is encouraging, for reasons relating to portfolio strategy, BioNTech opted not to participate in the further development of the program, including a planned Phase 3 trial. BioNTech and Genmab A/S (“Genmab”) will continue their collaboration under the existing agreements which was expanded in 2022. ADC Programs BNT323/DB-1303 is an ADC candidate targeting Human Epidermal Growth Factor 2 (“HER2”) that is being developed in collaboration with Duality Biologics (Suzhou) Co. Ltd. (“DualityBio”). BNT323/DB-1303 is being evaluated in a Phase 1/2 clinical trial (NCT05150691) in patients with advanced/unresectable, recurrent or metastatic HER2-expressing solid tumors. A potentially registrational cohort with HER2-expressing (IHC3+, 2+, 1+ or ISH-positive) patients with advanced/recurrent endometrial carcinoma has completed enrollment. Data from this cohort are expected in 2025.A confirmatory Phase 3 trial (NCT06340568) in patients with advanced endometrial cancer is planned to start in 2024.A pivotal Phase 3 trial (NCT06018337) evaluating BNT323/DB-1303 in patients with Hormone Receptor-positive (“HR+”) and HER2-low metastatic breast cancer (“BC”) that have progressed on hormone therapy and/or cyclin-dependent kinase 4/6 (“CDK4/6”) inhibition is ongoing.Topline data from the ongoing Phase 3 trial in HR+ and HER2-low metastatic BC that have progressed on hormone therapy and/or CDK4/6 inhibition are expected as early as 2025. BNT324/DB-1311 is an ADC candidate targeting B7H3 that is being developed in collaboration with DualityBio. A first-in-human, open-label Phase 1/2a clinical trial (NCT05914116) evaluating BNT324/DB-1311 in patients with advanced solid tumors is ongoing.In June 2024, BioNTech and DualityBio announced that BNT324/DB-1311 was granted Fast Track designation by the U.S. FDA for the treatment of patients with advanced/unresectable or metastatic castration-resistant prostate cancer who have progressed on or after standard systemic regimens.In July 2024, the U.S. FDA granted Orphan Drug designation to BNT324/DB-1311 for the treatment of patients with advanced or metastatic esophageal squamous cell carcinoma. BNT326/YL202 is an ADC candidate targeting HER3 that is being developed in collaboration with MediLink Therapeutics (Suzhou) Co., Ltd. (“MediLink”). A multicenter, international, open-label, first-in-human Phase 1 clinical trial (NCT05653752), sponsored by MediLink, evaluating BNT326/YL202 as a later-line treatment in patients with locally advanced or metastatic EGFR-mutated NSCLC or HR+ and HER2-negative BC is on partial clinical hold by the U.S. FDA, as announced on June 17, 2024. BioNTech and MediLink are working to address the U.S. FDA’s requirements and resolve the partial clinical hold.Preliminary data from this study were presented at the 2024 ASCO Annual Meeting. BNT326/YL202 demonstrated encouraging activity in heavily pretreated locally advanced/metastatic NSCLC and BC with an ORR of 42.3% (22 out of 52 evaluable patients) and a DCR of 94.2% (49/52), with responses seen from the first dose level at 0.5 mg/kg. The safety profile of BNT326/YL202 was consistent with its mechanism of action and dose-dependent. The most common TRAEs were due to hematologic toxicity and gastrointestinal disorders. 7.3% (4/55) of patients discontinued treatment due to TRAEs, and there were 3 treatment-related Grade 5 events (deaths) at higher doses. Further clinical development is expected to focus on dose levels below 4.0 mg/kg, where the safety profile was manageable and encouraging clinical activity was observed. Cell Therapy Programs BNT211 consists of two investigational medicinal products: a CAR-T cell product candidate targeting Claudin-6 (“CLDN6”)-positive solid tumors in combination with a CAR-T cell-amplifying RNA vaccine (“CARVac”) encoding CLDN6. A first-in-human, open-label, multi-center Phase 1 dose escalation and dose expansion basket trial (NCT04503278) evaluating CLDN6 CAR-T cells as monotherapy or in combination with CLDN6 CARVac in patients with CLDN6-positive relapsed or refractory solid tumors, including ovarian cancers and testicular germ cell tumors, is ongoing.A data update is expected to be presented at the 2024 ESMO Congress.

Advancing toward goal of ten or more potentially registrational trials running by the end of 2024: first patient dosed in Phase 3 clinical trial evaluating BNT323/DB-1303 in HR+ HER2-low chemotherapy-naïve metastatic breast cancer patients, and a second Phase 3 trial with BNT323/DB-1303 in recurrent endometrial cancer planned to start soon Presented clinical data at the American Association for Cancer Research (“AACR”) Annual Meeting for individualized and off-the-shelf mRNA-based cancer vaccine candidates based on iNeST and FixVac platforms, including three-year follow-up data of an investigator-initiated trial in patients with resected pancreatic ductal adenocarcinoma (“PDAC”) Planning to share additional clinical data from multiple clinical programs at the American Society of Clinical Oncology (“ASCO”) Annual Meeting, including bispecific antibodies BNT311/GEN1046 (acasunlimab) and BNT327/PM8002 and antibody-drug conjugate (“ADC”) BNT326/YL202 Continued development and commercial preparation for a 2024 season variant-adapted COVID-19 vaccine First quarter 2024 revenues of €187.6 million, net loss of €315.1 million and loss per share of €1.31 ($1.421) Maintained strong financial position with €16.9 billion in cash, cash equivalents and security investments Conference call and webcast scheduled for May 6, 2024, at 8:00 a.m. EDT (2:00 p.m. CEST) MAINZ, Germany, May 6, 2024 (GLOBE NEWSWIRE) -- BioNTech SE (Nasdaq: BNTX, “BioNTech” or “the Company”) today reported financial results for the three months ended March 31, 2024, and provided an update on its corporate progress. “In the past weeks, we have reported positive preliminary data for both our individualized and off-the-shelf mRNA-based candidates which further underline the potential of our iNeST and FixVac platforms. We look forward to providing more updates this year across our oncology portfolio, including our bispecific antibody and ADC programs,” said Prof. Ugur Sahin, M.D., CEO and Co-Founder of BioNTech. “In the remainder of the year, we plan to develop and commercialize a variant-adapted COVID-19 vaccine and accelerate our clinical development activities towards realizing the full potential of our oncology pipeline with a view to becoming a commercial company with marketed medicines for cancer and infectious diseases.” Financial Review for the First Quarter 2024 in millions €, except per share data First Quarter 2024 First Quarter 2023 Total Revenues 187.6 1,277.0 Net (Loss) / Profit (315.1) 502.2 (Loss) / Diluted Earnings per Share (1.31) 2.05 Total revenues reported were €187.6 million for the three months ended March 31, 2024, compared to €1,277.0 million for the comparative prior year period. The year-over-year change was mainly due to lower commercial revenues from the sales of BioNTech’s COVID-19 vaccine worldwide resulting from endemic-level demand for COVID-19 vaccines. Cost of sales were €59.1 million for the three months ended March 31, 2024, compared to €96.0 million for the comparative prior year period. The change was mainly due to recognizing lower cost of sales from BioNTech’s decreased COVID-19 vaccine sales, which included the share of gross profit that BioNTech owes its collaboration partner Pfizer Inc. (“Pfizer”) and royalty expenses based on BioNTech’s sales. In addition, cost of sales was impacted by expenses arising from inventory write-offs and destruction of inventory. Research and development (“R&D”) expenses were €507.5 million for the three months ended March 31, 2024, compared to €334.0 million for the comparative prior year period. R&D expenses were mainly influenced by progressing clinical studies for pipeline candidates. The increase was further driven by an increase in wages, benefits and social security expenses resulting from an increase in headcount. General and administrative (“G&A”) expenses reached €117.0 million for the three months ended March 31, 2024, compared to €111.8 million for the comparative prior year period. G&A expenses were primarily driven by increased expenses for IT environment and wages, benefits, and social security expenses resulting from an increase in headcount. Income taxes were realized with an amount of €16.7 million of tax income for the three months ended March 31, 2024, compared to €205.5 of tax expenses accrued for the comparative prior year period. The effective income tax rate for the three months ended March 31, 2024, was approximately 5.0% applicable on the negative income. Net loss was €315.1 million for the three months ended March 31, 2024, compared to a net profit of €502.2 million for the comparative prior year period. Cash and cash equivalents as well as security investments as of March 31, 2024, reached €16,939.3 million, comprising €8,976.6 million cash and cash equivalents and €7,962.7 million security investments, respectively. Loss per share was €1.31 for the three months ended March 31, 2024, compared to diluted earnings per share of €2.05 for the comparative prior year period. Shares outstanding as of March 31, 2024, were 237,725,735, excluding 10,826,465 shares held in treasury. “We started the year making good progress across our oncology pipeline. We dosed the first patient in our second pivotal Phase 3 trial and aim to have ten or more potentially registrational trials by the end of 2024. Revenues in the first quarter reflect the seasonal demand for COVID-19 vaccines, and we expect to recognize approximately 90% of our full year revenues in the last months of 2024, mostly in Q4 of 2024. With a strong cash position of €16.9 billion, we are well positioned to invest in our innovative R&D pipeline and scale the business for commercial readiness in oncology,” said Jens Holstein, CFO of BioNTech. “We remain committed to seizing the opportunity to transform the way cancer and infectious diseases are treated, especially with our tremendous experience in using our mRNA platforms. We will focus the remainder of the year on executing and delivering on this vision with the aim to drive sustainable long-term growth and to create future value for patients, society and our shareholders.” Outlook for the 2024 Financial Year The Company reiterates its prior outlook for the financial year: Total revenues for the 2024 financial year €2.5 billion - €3.1 billion BioNTech expects group revenues for the full 2024 financial year to be in the range of €2.5 to €3.1 billion. The range reflects certain assumptions, including, but not limited to, expectations regarding: the timing and granting of regulatory approvals and recommendations; COVID-19 vaccine uptake and price levels; inventory write-downs by BioNTech’s collaboration partner Pfizer that would negatively influence the Company’s revenues; seasonal variations in SARS-CoV-2 circulation and vaccination uptake, which are expected to lead to demand peaks in the autumn and winter compared to other seasons; and revenues from a pandemic preparedness contract with the German government as well as revenues from the BioNTech Group service businesses, namely InstaDeep Ltd., JPT Peptide Technologies GmbH, and in Idar-Oberstein at BioNTech Innovative Manufacturing Services GmbH. Generally, the Company continues to remain largely dependent on revenues generated in its collaboration partner’s territories in 2024.

Operational Review of the First Quarter 2024, Key Post Period-End Events and 2024 Outlook Omicron XBB.1.5-adapted Monovalent COVID-19 Vaccine (COMIRNATY®) BioNTech and Pfizer developed, manufactured and delivered their Omicron XBB.1.5-adapted monovalent COVID-19 vaccine, which has received multiple regulatory approvals, including full approvals, authorizations for emergency or temporary use, or marketing authorizations, in more than 40 countries and regions. BioNTech is now focused on preparing for variant strain vaccine adaptation to be ready for commercial launch ahead of the upcoming 2024/2025 vaccination season, pending approvals. COVID-19 – Influenza Combination Vaccine Program BNT162b2 + BNT161 is an mRNA-based combination vaccine program against COVID-19 and influenza being developed in collaboration with Pfizer. Top-line data from the Phase 1/2 trial (NCT05596734) demonstrated robust immune responses to influenza A, influenza B, and SARS-CoV-2 strains and that the safety pro the candidates was consistent with the pro the companies’ COVID-19 vaccine. A Phase 3 clinical trial (NCT06178991) is ongoing. Select Oncology Pipeline Highlights ADC Programs BNT323/DB-1303 is an ADC candidate targeting Human Epidermal Growth Factor 2 (“HER2”) that is being developed in collaboration with Duality Biologics (Suzhou) Co. Ltd. (“DualityBio”). The program has been granted Breakthrough Therapy designation by the U.S. Food and Drug Administration (“FDA”) for the treatment of advanced endometrial cancer in patients who progressed on or after treatment with immune checkpoint inhibitors. BNT323/DB-1303 is being evaluated in a Phase 1/2 clinical trial (NCT05150691) in patients with advanced/unresectable, recurrent or metastatic HER2-expressing solid tumors. A potentially registrational cohort is enrolling HER2-expressing (IHC3+, 2+, 1+ or ISH-positive) patients with advanced/recurrent endometrial carcinoma and aims to recruit 140 patients. A confirmatory Phase 3 trial (NCT06340568) in this patient population is planned to start in 2024. In January, the first patient was dosed in a pivotal Phase 3 trial (NCT06018337) evaluating BNT323/DB-1303 in patients with Hormone Receptor-positive (“HR+”) and HER2-low metastatic breast cancer that have progressed on hormone therapy and/or cyclin-dependent kinase 4/6 (“CDK4/6”) inhibition. BNT325/DB-1305 is an ADC candidate targeting TROP2 that is being developed in collaboration with DualityBio. In January, BioNTech and DualityBio received Fast Track designation for BNT325/DB-1305 from the U.S. FDA for the treatment of patients with platinum-resistant ovarian epithelial, fallopian tube, or primary peritoneal cancer who have received one to three prior systemic treatment regimens. A Phase 1/2 clinical trial (NCT05438329) is ongoing. BNT326/YL202 is an ADC candidate targeting HER3 that is being developed in collaboration with MediLink Therapeutics (Suzhou) Co., Ltd. (“MediLink”). A multicenter, open-label, first-in-human Phase 1 clinical trial (NCT05653752) evaluating BNT326/YL202 as a later-line treatment in patients with locally advanced or metastatic epidermal growth factor receptor (“EGFR”)-mutated non-small cell lung cancer (“NSCLC”) or HR+/HER2-negative breast cancer is ongoing in the United States and China. Preliminary data from this study are expected to be presented at the 2024 ASCO Annual Meeting. Next-Generation Immune Checkpoint Immunomodulator Programs BNT311/GEN1046 (acasunlimab) is a potential first-in-class bispecific antibody candidate combining PD-L1 checkpoint inhibition with 4-1BB costimulatory activation that is being developed in collaboration with Genmab A/S (“Genmab”). Data from a Phase 2 trial (NCT05117242) evaluating BNT311/GEN1046 in combination with pembrolizumab in pretreated NSCLC patients are expected to be presented at the 2024 ASCO Annual Meeting. BNT327/PM8002 is an anti-VEGF-A antibody candidate fused to a humanized anti-PD-L1 VHH being developed in collaboration with Biotheus Inc. (“Biotheus”). BNT327/PM8002 is currently being evaluated in Phase 1 and Phase 2/3 clinical trials in China to assess the efficacy and safety of the candidate as monotherapy or in combination with chemotherapy in various indications. An Investigational New Drug application has been accepted by the U.S. FDA for further studies in the United States, and global trials are planned to start this year. Monotherapy data from the Phase 1/2 trials are planned to be presented at the 2024 ASCO Annual Meeting. Cancer Vaccine Programs BNT116 is based on BioNTech’s FixVac platform, and is a wholly owned, systemically administered, off-the-shelf uridine mRNA-lipoplex based cancer vaccine candidate encoding six shared lung cancer associated antigens. A randomized, controlled Phase 2 clinical trial (NCT05557591) is ongoing to evaluate BNT116 in combination with cemiplimab versus cemiplimab alone as first-line treatment in patients with advanced NSCLC whose tumors express PD-L1 in ≥ 50% of tumor cells. In April 2024, data from a Phase 1 trial cohort (NCT05142189) were presented at the AACR Annual Meeting. Patients were treated with BNT116 in combination with docetaxel after progression on a PD-1/PD-L1 inhibitor and a platinum-based chemotherapy. Preliminary data of BNT116 in combination with docetaxel show encouraging antitumor activity, consistent induction of immune responses, a manageable safety profile, and no signs of additive toxicity. Efficacy results suggest that combination therapy with BNT116 and docetaxel was active with an overall response rate (“ORR”) of 30% and a disease control rate (“DCR”) of 85%. Autogene cevumeran (BNT122) is a uridine mRNA-lipoplex based cancer vaccine candidate for individualized neoantigen-specific immunotherapy (“iNeST”) being developed in collaboration with Genentech, Inc., a member of the Roche Group (“Genentech”). Autogene cevumeran is being evaluated in ongoing Phase 2 trials in adjuvant resected PDAC (NCT05968326), first-line melanoma (NCT03815058) and adjuvant colorectal cancer (“CRC”) (NCT04486378). Epidemiologic data including post-operative circulating tumor DNA (“ctDNA”) prevalence and prognostic value from a non-interventional, observational study (NCT04813627) in patients with resected high-risk stage II/III CRC are expected to be presented at the 2024 ASCO Annual Meeting. A Phase 2 clinical trial in an additional indication is planned. In April 2024, long-term follow-up data from an investigator-initiated Phase 1 trial in patients with resected PDAC were presented at the AACR Annual Meeting. The data showed that the individualized mRNA cancer vaccine candidate autogene cevumeran continues to show polyspecific T cell responses up to three years after vaccination and that vaccine responses correlate with delayed tumor recurrence. The investigator-initiated, single center Phase 1 trial (NCT04161755) evaluated the safety of autogene cevumeran in sequential combination with the anti-PD-L1 immune checkpoint inhibitor atezolizumab and standard-of-care chemotherapy in 16 patients with resected PDAC. Data from the 1.5-year median follow-up were previously published in Nature (Rojas, L.A et al. 2023). Cell Therapy Programs BNT211 consists of two investigational medicinal products: a CAR-T cell product candidate targeting Claudin-6 (“CLDN6”)-positive solid tumors in combination with a CAR-T cell-amplifying RNA vaccine (“CARVac”) encoding CLDN6. After determination of the recommended Phase 2 dose, BioNTech plans to initiate a pivotal trial in patients with germ cell tumors. BioNTech plans to present an analysis of real world evidence investigating overall survival and treatment patterns of patients with testicular germ cell tumors receiving palliative chemotherapy at the 2024 ASCO Annual Meeting.

Application based on results from the TROPION-Breast01 phase 3 trial Additional BLA under review in the U.S. for Daiichi Sankyo and AstraZeneca’s datopotamab deruxtecan for patients with advanced nonsquamous non-small cell lung cancer TOKYO & BASKING RIDGE, N.J.--(BUSINESS WIRE)-- Daiichi Sankyo (TSE: 4568) and AstraZeneca’s (LSE/STO/Nasdaq: AZN) Biologics License Application (BLA) for datopotamab deruxtecan (Dato-DXd) has been accepted in the U.S. for the treatment of adult patients with unresectable or metastatic hormone receptor (HR) positive, HER2 negative (IHC 0, IHC 1+ or IHC 2+/ISH-) breast cancer who have received prior systemic therapy for unresectable or metastatic disease. Datopotamab deruxtecan is a specifically engineered TROP2 directed DXd antibody drug conjugate (ADC) discovered by Daiichi Sankyo and being jointly developed by Daiichi Sankyo and AstraZeneca. The Prescription Drug User Fee Act (PDUFA) date, the U.S. Food and Drug Administration (FDA) action date for its regulatory decision, is January 29, 2025. The BLA is based on results from the pivotal TROPION-Breast01 phase 3 trial, which were presented at a Presidential Symposium at the European Society for Medical Oncology (#ESMO23) 2023 Congress and in an oral presentation at the 2023 San Antonio Breast Cancer Symposium (#SABCS23). In the trial, datopotamab deruxtecan demonstrated a statistically significant and clinically meaningful improvement for the dual primary endpoint of progression-free survival (PFS) compared to investigator’s choice of chemotherapy in patients with unresectable or metastatic HR positive, HER2 negative breast cancer previously treated with endocrine-based therapy and at least one systemic therapy. For the dual primary endpoint of overall survival (OS), interim results numerically favored datopotamab deruxtecan over chemotherapy but were not mature at the time of data cut-off. The trial is ongoing and OS will be assessed at future analyses. The safety pro datopotamab deruxtecan was consistent with that observed in other ongoing trials with no new safety concerns identified. The most common grade 3 or higher treatment-related adverse events in the datopotamab deruxtecan and chemotherapy arms, respectively, were neutropenia (1% vs. 31%), stomatitis (6% vs. 3%), fatigue (2% vs. 2%) and anemia (1% vs. 2%). “The FDA’s acceptance of the BLA brings us closer to providing patients with previously treated HR positive, HER2 negative breast cancer an alternative option to conventional chemotherapy earlier in the metastatic setting,” said Ken Takeshita, MD, Global Head, R&D, Daiichi Sankyo. “Following our recently accepted application for advanced nonsquamous non-small cell lung cancer in the U.S., along with additional regulatory reviews underway in China, the EU, Japan and other regions, we are working swiftly to bring datopotamab deruxtecan as a potential new treatment option to patients around the world.” “Despite marked progress in the treatment of HR positive, HER2 negative breast cancer, most patients with advanced disease develop endocrine resistance and face the prospect of one or several lines of chemotherapy,” said Susan Galbraith, MBBChir, PhD, Executive Vice President, Oncology R&D, AstraZeneca. “If approved, datopotamab deruxtecan has the potential to provide these patients an efficacious and better tolerated alternative to conventional chemotherapy.” An additional BLA for datopotamab deruxtecan based on results from the pivotal TROPION-Lung01 phase 3 trial is under review in the U.S. for the treatment of adult patients with locally advanced or metastatic nonsquamous non-small cell lung cancer (NSCLC) who have received prior systemic therapy. Additional regulatory submissions for datopotamab deruxtecan in lung and breast cancer are underway globally. About TROPION-Breast01 TROPION-Breast01 is a global, randomized, multicenter, open-label phase 3 trial evaluating the efficacy and safety of datopotamab deruxtecan versus investigator’s choice of single-agent chemotherapy (eribulin, capecitabine, vinorelbine or gemcitabine) in patients with unresectable or metastatic HR positive, HER2 negative (IHC 0, IHC 1+ or IHC 2+/ISH-) breast cancer who have progressed on and are not suitable for endocrine therapy per investigator assessment and have received at least one additional systemic therapy for unresectable or metastatic disease. The dual primary endpoints of TROPION-Breast01 are PFS as assessed by blinded independent central review and OS. Key secondary endpoints include objective response rate, duration of response, investigator-assessed PFS, disease control rate, time to first subsequent therapy and safety. TROPION-Breast01 enrolled more than 700 patients in Africa, Asia, Europe, North America and South America. For more information visit ClinicalTrials.gov. About Hormone Receptor Positive, HER2 Negative Breast Cancer More than 275,000 breast cancer cases were diagnosed in the U.S. in 2022.1 HR positive, HER2 negative breast cancer is the most common subtype, accounting for more than 65% of diagnosed cases.2 Breast cancer is considered HR positive, HER2 negative when tumors test positive for estrogen and/or progesterone hormone receptors and negative for HER2 (measured as HER2 score of IHC 0, IHC 1+ or IHC 2+/ISH-).2,3 Standard initial treatment for this subtype of breast cancer is endocrine therapy but most patients with advanced disease will develop resistance, underscoring the need for additional options.4,5 TROP2 is a protein broadly expressed in HR positive, HER2 negative breast cancer and is associated with increased tumor progression and poor survival.6,7 About Datopotamab Deruxtecan (Dato-DXd) Datopotamab deruxtecan (Dato-DXd) is an investigational TROP2 directed ADC. Designed using Daiichi Sankyo’s proprietary DXd ADC Technology, datopotamab deruxtecan is one of six DXd ADCs in the oncology pipeline of Daiichi Sankyo, and one of the most advanced programs in AstraZeneca’s ADC scientific platform. Datopotamab deruxtecan is comprised of a humanized anti-TROP2 IgG1 monoclonal antibody, developed in collaboration with Sapporo Medical University, attached to a number of topoisomerase I inhibitor payloads (an exatecan derivative, DXd) via tetrapeptide-based cleavable linkers. A comprehensive global clinical development program is underway with more than 20 trials evaluating the efficacy and safety of datopotamab deruxtecan across multiple cancers, including NSCLC, triple negative breast cancer and HR positive, HER2 negative breast cancer. About the Daiichi Sankyo and AstraZeneca Collaboration Daiichi Sankyo and AstraZeneca entered into a global collaboration to jointly develop and commercialize ENHERTU in March 2019 and datopotamab deruxtecan in July 2020, except in Japan where Daiichi Sankyo maintains exclusive rights for each ADC. Daiichi Sankyo is responsible for the manufacturing and supply of ENHERTU and datopotamab deruxtecan. About the DXd ADC Portfolio of Daiichi Sankyo The DXd ADC portfolio of Daiichi Sankyo currently consists of six ADCs in clinical development across multiple types of cancer. ENHERTU, a HER2 directed ADC, and datopotamab deruxtecan, a TROP2 directed ADC, are being jointly developed and commercialized globally with AstraZeneca. Patritumab deruxtecan (HER3-DXd), a HER3 directed ADC, ifinatamab deruxtecan (I-DXd), a B7-H3 directed ADC, and raludotatug deruxtecan (R-DXd), a CDH6 directed ADC, are being jointly developed and commercialized globally with Merck & Co., Inc., Rahway, N.J. USA. DS-3939, a TA-MUC1 directed ADC, is being developed by Daiichi Sankyo. Designed using Daiichi Sankyo’s proprietary DXd ADC Technology to target and deliver a cytotoxic payload inside cancer cells that express a specific cell surface antigen, each ADC consists of a monoclonal antibody attached to a number of topoisomerase I inhibitor payloads (an exatecan derivative, DXd) via tetrapeptide-based cleavable linkers.
