BioNTech SE (Nasdaq: BNTX, "BioNTech" or "the Company") today reported financial results for the three and nine months ended September 30, 2025 and provided an update on its corporate progress.

"In the third quarter, we made substantial progress in executing against our oncology strategy. We advanced our priority pan-tumor programs, mRNA cancer immunotherapies and pumitamig. Simultaneously, we further broadened these programs to include evaluation of novel combinations with the aim to deliver differentiated or best-in-class therapeutic profiles," said Prof. Ugur Sahin, M.D., Chief Executive Officer and Co-Founder of BioNTech . "Our collaboration with Bristol Myers Squibb on pumitamig is already demonstrating the strength of this partnership, with multiple additional pivotal trials in preparation with pumitamig planned to start this and next year. This illustrates our commitment to delivering truly transformative options for patients in need."

Financial Review for Third Quarter and Year-to-Date 2025

Revenues for the three months ended September 30, 2025, were €1,518.9 million, compared to €1,244.8 million for the comparative prior year period. For the nine months ended September 30, 2025, revenues were €1,962.5 million, compared to €1,561.1 million for the comparative prior year period. The increases in both quarterly and year-to-date revenues compared to the prior year were primarily driven by revenues related to BioNTech's collaboration with BMS that were recognized in the third quarter of 2025. This increase was partially offset by lower sales volumes of BioNTech's COVID-19 vaccines.

Research and development ("R&D") expenses were €564.8 million for the three months ended September 30, 2025, compared to €550.3 million for the comparative prior year period. For the nine months ended September 30, 2025, R&D expenses were €1,599.5 million, compared to €1,642.4 million for the comparative prior year period. Year-to-date R&D expenses were mainly driven by the start of late-stage trials for immuno-oncology ("IO") and antibody-drug conjugate ("ADC") development programs and partly offset by cost savings resulting from active portfolio management.

Sales, general and administrative ("SG&A") expenses, in total, amounted to €148.5 million for the three months ended September 30, 2025, compared to €150.5 million for the comparative prior year period. For the nine months ended September 30, 2025, SG&A expenses were €406.5 million, compared to €466.9 million for the comparative prior year period. The year-to-date and quarter-to-quarter decreases were mainly driven by lower external costs, partially compensated by an ongoing commercial build-up.

Other operating result amounted to negative €704.2 million during the three months ended September 30, 2025, compared to negative €354.6 million for the comparative prior year period. For the nine months ended September 30, 2025, other operating result amounted to negative €730.1 million compared to negative €616.9 million for the prior year period. The increase in other operating expenses compared to the third quarter of 2024 was primarily influenced by the settlement of a contractual dispute.

Net loss was €28.7 million for the three months ended September 30, 2025, compared to a net income of €198.1 million for the comparative prior year period. For the nine months ended September 30, 2025, net loss was €831.1 million, compared to a net loss of €924.8 million for the comparative prior year period.

Basic and diluted loss per share was €0.12 for the three months ended September 30, 2025, compared to a basic earnings per share of €0.82 and diluted earnings per share of €0.81 for the comparative prior year period. For the nine months ended September 30, 2025, basic and diluted loss per share was €3.45, compared to a basic and diluted loss per share of €3.83 for the comparative prior year period.

Cash and cash equivalents plus security investments as of September 30, 2025, reached €16,704.9 million, comprising €10,092.9 million in cash and cash equivalents, €4,275.6 million in current security investments and €2,336.4 million in non-current security investments.

Shares outstanding as of September 30, 2025, were 240,455,450, excluding 8,096,750 shares held in treasury.

"The receipt of $1.5 billion from our partnership with Bristol Myers Squibb further underscores the strategic value of our collaborations not only in the long but also in the short term," said Ramón Zapata, Chief Financial Officer at BioNTech . "We are increasing our 2025 full year revenue guidance to €2.6-2.8 billion. At the same time, we continue to optimize our cost base to support a sustainable development trajectory and ensure operational efficiency."

2025 Financial Year Guidance ⁵ :

BioNTech has increased its previous revenue guidance and now expects its revenues for the full 2025 financial year to be in the range of €2,600 - €2,800 million. With regards to COVID-19 vaccine franchise, the guidance reflects the following assumptions: relatively stable COVID-19 vaccine pricing and market share as compared to 2024; inventory write-downs and other charges estimated to be approximately 15% of BioNTech's share of gross profit from COVID-19 vaccine sales in Pfizer Inc.'s ("Pfizer") territory; and anticipated revenues from a pandemic preparedness contract with the German government. Current and potential further developments in law, global public policy, international trade, and public sentiment as they continue to evolve could further impact the anticipated COVID-19 vaccine revenues and expenses. The revenue guidance also includes anticipated revenues from collaborations, and from the BioNTech Group service businesses.

Planned 2025 Financial Year Expenses and Capex:

BioNTech has lowered expense guidance ranges for R&D, SG&A and capital expenditures for operating activities for the 2025 financial year.

The Company expects to continuously focus investments on R&D and scaling the business for late-stage development and commercial readiness in oncology, while remaining cost-disciplined. Strategic capital allocation will continue to be a key driver of the Company's trajectory. As part of BioNTech's strategy, the Company may continue to evaluate appropriate corporate development opportunities with the aim of driving sustainable long-term growth and creating future value.

Select Oncology Pipeline Updates

Next-Generation Immunomodulators and Combinations

Pumitamig (BNT327/BMS986545) is a bispecific antibody candidate combining PD-L1 checkpoint inhibition with VEGF-A neutralization that is being developed in collaboration with BMS.

• In September 2025, interim data from a global Phase 2 clinical trial ( NCT06449209 ) evaluating pumitamig in combination with chemotherapy in patients with untreated extensive-stage small-cell lung cancer ("ES-SCLC") were presented at the IASLC 2025 World Conference on Lung Cancer ("WCLC"). The data showed encouraging anti-tumor responses, with a positive trend in the secondary endpoint, progression free survival ("PFS") and a manageable safety profile with no new safety signals and a low discontinuation rate. The clinical trial is fully enrolled and treatment is ongoing, including further cohorts evaluating pumitamig in combination with chemotherapy in patients with SCLC whose disease has progressed on first- or second-line treatment. A global Phase 3 clinical trial (ROSETTA Lung-01; NCT06712355 ) is being conducted to evaluate pumitamig as a first-line treatment in combination with chemotherapy compared to atezolizumab in combination with chemotherapy in patients with untreated ES-SCLC.
  
  
• A global Phase 2/3 clinical trial (ROSETTA Lung-02; N CT06712316 ) is being conducted to evaluate pumitamig in combination with chemotherapy compared to pembrolizumab and chemotherapy in patients with first-line non-small cell lung cancer ("NSCLC"). The Phase 2 part of the seamless Phase 2/3 trial achieved full enrollment and the Phase 3 portion is recruiting.
  
  
• A global Phase 2 clinical trial ( NCT06449222 ) is being conducted to evaluate pumitamig in combination with chemotherapy as a first- and second-line treatment for patients with locally advanced or metastatic triple-negative breast cancer ("TNBC"). Interim data from this clinical trial are planned to be presented at the San Antonio Breast Cancer Symposium ("SABCS") in December. A global Phase 3 clinical trial in patients with first-line TNBC (ROSETTA Breast-01; NCT07173751 ) is planned to start by the end of 2025.
  
  
• Additional pivotal Phase 2/3 clinical trials for pumitamig in first-line microsatellite stable colorectal cancer ("CRC") (ROSETTA CRC-203; NCT07221357 ) and first-line gastric cancer (ROSETTA GI-204; NCT07221149 ) are planned.

In the last quarter, BioNTech initiated several signal-seeking clinical trials to evaluate pumitamig with the Company's proprietary assets:

• In August, the first patient was dosed in a Phase 1/2 clinical trial ( NCT07079631 ) to evaluate BioNTech and Genmab AS's ("Genmab") bispecific antibody candidate BNT314/GEN1059 in combination with pumitamig and chemotherapy in patients with advanced CRC.
  
  
• Also in August, the first patient was dosed in a Phase 1/2 clinical trial ( NCT07070232 ) to evaluate pumitamig in combination with BioNTech and MediLink Therapeutics' ("MediLink") HER3 ADC candidate BNT326/YL202 and BNT326/YL202 as monotherapy in advanced solid tumors.
  
  
• In September, the first patient was dosed in a Phase 1/2 clinical trial ( NCT07147348 ) to evaluate BNT3212, a novel bispecific ADC candidate targeting EGFR and HER3, as monotherapy and in combination with pumitamig in patients with advanced solid tumors.
  
  
• In October, the first patient was dosed in a Phase 1/2 clinical trial ( NCT07111520 ) to evaluate BioNTech and MediLink's BNT326/YL202 in combination with pumitamig in advanced NSCLC.

Antibody-Drug Conjugates

Trastuzumab pamirtecan (BNT323/DB-1303) is an ADC candidate targeting HER2 that is being developed in collaboration with Duality Biologics (Suzhou) Co. Ltd.'s ("DualityBio").

• A Phase 1/2 clinical trial ( NCT05150691 ) is being conducted to evaluate trastuzumab pamirtecan in patients with advanced HER2-expressing tumors. A potentially registrational cohort with HER2-expressing (IHC3+, 2+, 1+ or ISH-positive) patients with recurrent endometrial cancer is ongoing. Data are expected to be shared at a medical conference in 2026. BioNTech and DualityBio continue discussions with the FDA and now plan to file a biologics license application ("BLA") in 2026, subject to regulatory feedback.
  
  
• In September, the first patient was dosed in a global Phase 3 clinical trial ( NCT06340568 ) to evaluate trastuzumab pamirtecan in patients with advanced endometrial cancer.
  
  
• Also in September, BioNTech and DualityBio announced that the pivotal Phase 3 clinical trial ( NCT06265428 ) which DualityBio is conducting in China to evaluate trastuzumab pamirtecan versus trastuzumab emtansine ("T-DM1") in patients with HER2-positive unresectable or metastatic breast cancer who have previously received trastuzumab and a taxane-based chemotherapy met its primary endpoint of PFS at a pre-specified interim analysis. A global Phase 3 clinical trial (DYNASTY-Breast02, NCT06018337 ) for trastuzumab pamirtecan in HR-positive, HER2-low metastatic breast cancer is ongoing. Data are expected in 2026.

BNT325/DB-1305 is a TROP2-targeted ADC candidate that is being developed in collaboration with DualityBio.

• A Phase 1/2 clinical trial ( NCT05438329 ) evaluating BNT325/DB-1305 in patients with advanced solid tumors is ongoing. In October, data from this trial in patients with pretreated TNBC were presented at the European Society For Medical Oncology ("ESMO") Congress 2025. Data showed encouraging anti-tumor activity and a manageable safety profile.

mRNA Cancer Immunotherapies

Autogene cevumeran (BNT122/RO7198457) is an mRNA cancer immunotherapy candidate for individualized neoantigen-specific immunotherapy ("iNeST") that is being developed in collaboration with Genentech, Inc. ("Genentech"), a member of the Roche Group ("Roche").

• In October, data from a randomized Phase 2 clinical trial (IMCODE001; NCT03815058 ) evaluating the efficacy and safety of autogene cevumeran in combination with pembrolizumab versus pembrolizumab alone as a potential first-line treatment for patients with previously untreated advanced melanoma were presented at the 2025 ESMO Congress. While, as previously disclosed, the trial did not meet its primary efficacy endpoint of statically significant improvement of PFS in this advanced and aggressive tumor type, a numerical trend favoring the combination arm in overall survival ("OS") and PFS was observed, with the breadth of immune response correlating with a prolonged PFS in the combination arm. Autogene cevumeran induced and expanded high-magnitude and durable immune responses against the encoded neoantigens that persisted for up to 1.5 years after treatment completion. The combination of autogene cevumeran with PD-L1 checkpoint blockade was well tolerated and adverse events were consistent with the known safety profiles of the individual trial treatments, with no new safety signals observed.

BNT111 is based on BioNTech's fully owned, off-the-shelf FixVac platform, and encodes four melanoma-associated antigens.

• In October, data from a randomized Phase 2 clinical trial (BNT111-01; NCT04526899 ) conducted in collaboration with Regeneron Pharmaceuticals Inc. ("Regeneron") to evaluate BNT111 in combination with cemiplimab in patients with anti-PD-(L)1 refractory/relapsed, unresectable Stage III or IV melanoma were presented at the 2025 ESMO Congress. As previously disclosed, the trial met its primary endpoint demonstrating statistically significant improvement in objective response rate ("ORR") in patients treated with BNT111 in combination with cemiplimab, as compared to an historical control. The data showed that the combination of BNT111 and cemiplimab induced anti-tumor responses that were deep and durable and a manageable safety profile for BNT111 as a single agent and in combination.

BNT116 is based on BioNTech's fully owned, off-the-shelf FixVac platform, and is designed to elicit an immune response to six tumor-associated antigens that were identified to be frequently expressed in NSCLC.

• A Phase 1 clinical trial (LuCa-MERIT-1; NCT05142189 ) is being conducted to evaluate BNT116 as monotherapy and in several treatment combinations, including with chemotherapy, cemiplimab, and BioNTech's proprietary assets across various treatment lines and clinical settings in patients with NSCLC. In September, data were presented at the IASLC 2025 WCLC from a cohort evaluating BNT116 in combination with cemiplimab as consolidation treatment in patients with NSCLC after receiving concurrent chemoradiotherapy. BNT116 in combination with cemiplimab demonstrated encouraging event-free and overall survival rates and a manageable safety profile.
