First Quarter 2026 Unaudited Financial Results Highlights1 14 1. All numbers have been rounded. 2. In addition to BioNTech's results determined in accordance with International Financial Reporting Standards ("IFRS"), or IFRS Accounting Standards, or IFRS results, BioNTech reports certain adjusted, non-IFRS measures used internally as a supplemental measure of our business performance (each referred to with the prefix "Adjusted" or, as a whole, "Adjusted Results"). The calculation of these measures and the adjusted results as a whole is based on the concepts of the applicable IFRS Accounting Standards, but includes certain adjustments. Reconciliation of the adjusted results to BioNTech's measures based on IFRS Accounting Standards and more information can be found in the appendix and in BioNTech's Report on Form 6-K for the period ended March 31, 2026, filed on May 5, 2026, which is available at www.sec.gov. While non-IFRS measures may offer additional insights, BioNTech's non-IFRS measures are not, and should not be viewed as a substitute for their most directly comparable IFRS Accounting Standards measures, and should always be considered alongside our financial statements prepared in accordance with IFRS Accounting Standards. 3. Cash and cash equivalents plus security investments as of March 31, 2026, reached €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. 118 M€ Revenues Adjusted Research & Development Expenses2 (IFRS: 557 M€) 527 M€ Sales, Marketing, General & Administrative Expenses 151 M€ Cash and Cash Equivalents plus Security Investments3 16.8 B€

All Numbers have been rounded and may not add up to the totals. Presentation of the consolidated statements of profit or loss has been condensed. 2. In addition to BioNTech's results determined in accordance with International Financial Reporting Standards ("IFRS"), or IFRS Accounting Standards, or IFRS results, BioNTech reports certain adjusted, non-IFRS measures used internally as a supplemental measure of our business performance (each referred to with the prefix "Adjusted" or, as a whole, "Adjusted Results"). The calculation of these measures and the adjusted results as a whole is based on the concepts of the applicable IFRS Accounting Standards, but includes certain adjustments. Reconciliation of the adjusted results to BioNTech's measures based on IFRS Accounting Standards and more information can be found in BioNTech's Report on Form 6-K for the period ended March 31, 2026, filed on May 5, 2026, which is available at www.sec.gov. While non-IFRS measures may offer additional insights, BioNTech's non-IFRS measures are not, and should not be viewed as a substitute for their most directly comparable IFRS Accounting Standards measures, and should always be considered alongside our financial statements prepared in accordance with IFRS Accounting Standards. 3. Tax effects are not considered as part of BioNTech's non-IFRS adjustments. 21
