"We will continue to focus on accelerating our key strategic programs as we remain steadfast in our vision to translate our science into survival for patients living with cancer."

Financial Review for First Quarter 2026


in millions €, except per share data	First Quarter 2026		First Quarter 2025
in millions €, except per share data	IFRS Results	Adjusted Results²	IFRS Results	Adjusted Results²
Revenues	118.1	118.1	182.8	182.8
Net loss	(531.9)	(494.6)	(415.8)	(430.8)
Diluted loss per share	(2.10)	(1.95)	(1.73)	(1.79)

Revenues for the first quarter of 2026 were €118.1 million, compared to €182.8 million for the comparative prior year period. The decrease was primarily driven by lower revenues of BioNTech's COVID-19 vaccines.

Research and development ("R&D") expenses were €557.0 million for the first quarter of 2026, compared to €525.6 million for the comparative prior year period. R&D expenses were mainly driven by higher expenses for the development of immuno-oncology ("IO") and antibody-drug conjugate ("ADC") programs, in particular pumitamig and gotistobart, as well as costs from operations of entities acquired during 2025, BioNTech China (previously Biotheus) and CureVac, and an impairment of an intangible asset. These effects were partly offset by lower R&D expenses related to the Company's COVID‑19 vaccine collaboration with Pfizer Inc. ("Pfizer").

Adjusted R&D expenses were €527.1 million for the first quarter of 2026, compared to €525.6 million for the comparative prior year period. For the first quarter of 2026, adjusted R&D expenses exclude the impairment of an intangible asset.

Sales, general and administrative ("SG&A") expenses⁵ were €150.8 million for the first quarter of 2026, compared to €120.6 million for the comparative prior year period. The increase was mainly driven by the ongoing commercial build-up and the inclusion of operations of entities acquired in 2025, BioNTech China (previously Biotheus) and CureVac. These costs were partly offset by a reduction in external services.

Net loss was €531.9 million for the first quarter of 2026, compared to a net loss of €415.8 million for the comparative prior year period.

Adjusted net loss was €494.6 million for the first quarter of 2026, compared to an adjusted net loss of €430.8 million for the comparative prior year period.

Diluted loss per share was €2.10 for the first quarter of 2026, compared to a diluted loss per share of €1.73 for the comparative prior year period.

Adjusted diluted loss per share was €1.95 for the first quarter of 2026, compared to adjusted diluted loss per share of €1.79 for the comparative prior year period.

Cash, cash equivalents and security investments as of March 31, 2026, were €16,763.3 million, comprising €9,939.4 million in cash and cash equivalents, €4,696.9 million in current security investments disclosed as financial assets and €2,127.0 million in non-current security investments disclosed as financial assets.

Shares outstanding as of March 31, 2026, were 252,884,261, excluding 6,143,226 shares held in treasury

"Our revenues for the first quarter reflect the seasonal demand for COVID-19 vaccines and are in line with our expectations," said Ramón Zapata, Chief Financial Officer at BioNTech. "We are committed to a diligent capital allocation strategy that empowers us to pursue our goal of evolving into a leading biopharmaceutical company with multiple oncology products by 2030."

Reaffirmed 2026 Financial Year Guidance⁶:

Revenues for the 2026 financial year

€2,000 – €2,300 m

In 2026, BioNTech anticipates lower COVID-19 vaccine revenues compared to 2025, driven by declines in both the European and United States markets. The United States continues to be a competitive and dynamic market, where, as a result, lower revenues are expected. In Europe, the Company expects lower revenues as it defends its market share and begins managing the transition away from multi-year contracts. In Germany specifically, BioNTech recognizes direct sales of its COVID-19 vaccines as revenue. Hence, the anticipated declines in sales of COVID-19 vaccines in Germany will have a direct impact on the Company's topline, whereas revenues outside of Germany only affect the Company's topline as part of the 50% gross profit split with its partner Pfizer. Per the outlined partnership terms, revenues from the collaboration with Bristol Myers Squibb Company ("BMS") in 2026 are expected to be broadly in line with 2025. Revenues from the pandemic preparedness contract with the German government and service businesses are expected to remain stable.

Planned 2026 Financial Year Adjusted Expenses⁶:

Adjusted R&D expenses		€2,200 – €2,500 m
Adjusted SG&A expenses⁵		€700 – €800 m

BioNTech will continue to 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 foster innovation and 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.

Planned Capital Return to Shareholders

The Management Board and Supervisory Board expect to authorize a share repurchase program of BioNTech's American Depositary Shares ("ADSs"), pursuant to which the Company may repurchase ADSs in the amount of up to $1.0 billion over the next twelve months. BioNTech expects to use the repurchased ADSs to satisfy obligations in the ordinary course of business. The program is designed to enhance capital efficiency and support long-term value creation to execute BioNTech's objective to become a multi-product company by 2030.

Manufacturing Footprint Consolidation

BioNTech continues to allocate capital strategically while optimizing capacities broadly to drive operational efficiency and sustainable value creation. To this end, BioNTech plans to align and consolidate its manufacturing network further where excess capacity is expected, due to evolving supply needs, mergers and acquisitions, BioNTech's partners' manufacturing capacities and completion of contracts.

BioNTech plans to exit operations at the manufacturing sites in Idar-Oberstein, Marburg, and Singapore as well as CureVac's sites, affecting up to approximately 1,860 positions in total. The exit from the sites in Idar-Oberstein, Marburg, and Tübingen is planned by the end of 2027, while operations in Singapore are expected to conclude in Q1 2027. For each of these manufacturing sites, BioNTech is exploring divestment options, including a partial or total sale.

BioNTech expects cost savings to ramp up over time, potentially reaching approximately €500 million in recurring annual savings upon full implementation of the measures in 2029.⁷ These savings are intended to support the Company's capital allocation to further advance its growing oncology pipeline toward commercialization.

BioNTech continues to ensure a robust drug supply via its established manufacturing network. No impact on commercial or clinical supply nor contractual obligations is expected as the affected sites will become underutilized or idle in the next 24 months.

Select Oncology Pipeline Updates

Next-Generation Immunomodulators and Combinations

Pumitamig (BNT327/BMS986545) is an investigational bispecific immunomodulator combining PD-L1⁸ checkpoint inhibition with VEGF-A neutralization that is being developed in collaboration with BMS.

In the first quarter of 2026, the following pivotal trials evaluating pumitamig were initiated:
- A global Phase 3 clinical trial in patients with first-line triple-negative breast cancer ("TNBC") (ROSETTA Breast-01; NCT07173751).
- A global Phase 2/3 clinical trial in first-line microsatellite stable colorectal cancer ("MSS-CRC") (ROSETTA CRC-203; NCT07221357).
- A global Phase 2/3 clinical trial in first-line gastric cancer (ROSETTA Gastric-204; NCT07221149).
- A global Phase 3 clinical trial (ROSETTA Lung-201; NCT07361497) is being conducted to evaluate pumitamig compared to durvalumab following concurrent chemoradiation therapy in patients with unresectable stage III non-small cell lung cancer ("NSCLC").
- A global Phase 3 clinical trial (ROSETTA Lung-202; NCT07361510) is being conducted to evaluate pumitamig compared to pembrolizumab as a first-line treatment for patients with advanced PD-L1 ≥ 50% NSCLC.
A global Phase 2/3 clinical trial (ROSETTA Lung-02; NCT06712316) is ongoing to evaluate pumitamig in combination with chemotherapy compared to pembrolizumab and chemotherapy in patients with first-line NSCLC. The Phase 3 part of the trial is currently recruiting. Data from the Phase 2 part of the trial are expected at the American Society of Clinical Oncology ("ASCO") Annual Meeting 2026 (May 29 - June 2, 2026).
Pumitamig is also being evaluated in additional solid tumor indications, including first-line hepatocellular carcinoma ("HCC"), second-line glioblastoma ("GBM"), first-line pancreatic ductal adenocarcinoma ("PDAC") and first-line renal cell carcinoma ("RCC") in various Phase 1/2 and Phase 2 trials, both as monotherapy and in combination with standard of care.
BioNTech has several signal-seeking clinical trials ongoing evaluating pumitamig with the Company's proprietary assets. These trials will inform the dose selection for pumitamig and explore anti-tumor activity in multiple tumors for later-stage development. Multiple data readouts from these combinations are expected in 2026.
In April 2026, BioNTech and Boehringer Ingelheim announced a clinical trial collaboration to assess the safety, tolerability and early clinical activity of pumitamig in combination with obrixtamig (BI 764532), Boehringer Ingelheim's investigational DLL3/CD3 T‑cell engager, in extensive‑stage small cell lung cancer ("ES-SCLC"). Under the agreement, BioNTech will supply pumitamig and Boehringer Ingelheim will be the regulatory sponsor of the Phase 1b/2 trial.

Gotistobart (BNT316/ONC-392) is a tumor microenvironment-selective regulatory T cell depletion candidate that targets CTLA-4 and is being developed in collaboration with OncoC4, Inc. ("OncoC4").

A global Phase 3 clinical trial (PRESERVE-003; NCT05671510) is ongoing to evaluate the efficacy and safety of gotistobart as monotherapy in patients with metastatic squamous NSCLC that progressed under previous platinum-based chemotherapy and PD-(L)1-inhibitor treatment.
In March 2026, updated data from the non-pivotal dose-confirmation stage, the first of two stages of the global Phase 3 clinical trial, were presented at the European Lung Cancer Congress ("ELCC"). Gotistobart demonstrated a clinically meaningful overall survival benefit compared to standard of care chemotherapy and a manageable safety profile in patients with squamous NSCLC whose disease had progressed following anti-PD-(L)1 therapy and platinum-based chemotherapy.
Based on current event accrual projections, interim data from the pivotal stage of the two-stage Phase 3 clinical trial are expected in 2026.
In January 2026, gotistobart received Orphan Drug Designation from the U.S. Food and Drug Administration ("FDA") for the treatment of squamous NSCLC. In 2022, gotistobart received Fast Track Designation from the FDA for the treatment of patients with metastatic NSCLC whose disease progressed on prior anti-PD-(L)1 therapy.

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. ("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 ("EC") is fully recruited.
In April 2026, updated data from this trial were presented at the Society of Gynecologic Oncology ("SGO") Annual Meeting. Trastuzumab pamirtecan demonstrated encouraging clinical efficacy across all HER2 expression levels and regardless of prior immunotherapy treatment. The safety profile in patients with pretreated advanced or metastatic EC was manageable and generally consistent with that of HER2-targeted biologics.
BioNTech and DualityBio plan to file a biologics license application ("BLA") in 2026, subject to regulatory feedback.
A Phase 3 trial (FERN-EC-01, NCT06340568) is being conducted to evaluate trastuzumab pamirtecan compared to investigator's choice of chemotherapy in patients with advanced and HER2-expessing recurrent EC.
A global Phase 3 clinical trial (DYNASTY-Breast02, NCT06018337) to evaluate trastuzumab pamirtecan in patients with HR-positive, HER2-low metastatic breast cancer is ongoing. Based on current event accrual projections, data are expected in 2026.

BNT324/DB-1311 is an ADC candidate targeting B7H3 that is being developed in collaboration with DualityBio.

In February 2026, updated data from a Phase 1/2 clinical trial (NCT05914116) were presented at the ASCO Genitourinary Cancers Symposium. BNT324/DB-1311 demonstrated durable efficacy in heavily pretreated metastatic castration-resistant prostate cancer ("mCRPC") patients with no new safety signals reported.
In April 2026, updated data from this trial were presented at the SGO Annual Meeting. BNT324/DB-1311 showed encouraging efficacy in previously treated cervical cancer and platinum resistant ovarian cancer ("PROC") particularly in patients with treatment-naïve cervical cancer. The safety profile in gynecologic malignancies was consistent with previous reports, and no new safety signals were observed.
A Phase 3 clinical trial (NCT07365995) to evaluate BNT324/DB-1311 compared to docetaxel in patients with mCRPC, is expected to initiate in 2026.
