Based on the recommendation of the Audit Committee, the Supervisory Board proposes the following resolution:

KG Wirtschaftsprüfungsgesellschaft, based in Stuttgart (Cologne branch; Börsenplatz 1, 50667 Cologne) is appointed as the auditor and group auditor for the 2026 financial year and as the auditor for any audit or review of interim financial reports (half-year financial reports and quarterly reports) for the 2026 financial year and for the first quarter of the 2027 financial year.
6.Resolution on the approval of the Compensation Report
In accordance with section 162 of the German Stock Corporation Act (AktG), the Management Board and Supervisory Board have prepared a report on the compensation granted and owed to each individual current or former member of the Management Board and Supervisory Board in the 2025 financial year. This compensation report will be submitted to the Annual General Meeting for approval in accordance with section 120a (4) AktG.
The compensation report was audited by the auditor in accordance with section 162 (3) AktG to determine whether the disclosures pursuant to section 162 (1) and (2) AktG were made. The report on the audit of the compensation report is attached to the compensation report.
The Management Board and the Supervisory Board propose that the compensation report for the 2025 financial year, prepared and audited in accordance with section 162 AktG, be approved.
The compensation report is available from the time the Annual General Meeting is convened on our website at
https://investors.biontech.de/agm/agm-2026
The compensation report will be available there during the Annual General Meeting.
7.Resolution on the amendment of Section 9 para. 1 of the Articles of Association to increase the size of the Supervisory Board
The Supervisory Board of BioNTech SE currently consists of six members, in accordance with article 40 para. 2 and 3 of Council Regulation (EC) No. 2157/2001 of October 8, 2001, on the Statute for a European Company (SE) (“SE Regulation”), section 17 para. 1, second sentence of the SE Implementation Act (“SEAG”), and section 9 para. 1 of the Company’s Articles of Association. The number of Supervisory Board members is now
3
Germany 17275785.16


to be increased from six to eight, and section 9 para. 1 of the Company’s Articles of Association is to be amended accordingly.
The proposed expansion of the Supervisory Board is intended to take into account the Company’s sustained growth, the increased demands on the work of the Supervisory Board, particularly with regard to required knowledge, professional experience, diversity, and internationality, as well as the workload associated with the diverse tasks and responsibilities of the Supervisory Board members. In particular, supplementing or expanding the expertise on the Supervisory Board in the areas of oncology, marketing (product launches), as well as clinical development and the scientific field in general, is of crucial importance, especially given the Company’s current situation. The proposed expansion of the Supervisory Board opens the possibility of gaining the necessary additional expertise for the work of the Supervisory Board while retaining the experience of the current members, and thus contributes significantly to ensuring that the Supervisory Board can continue to monitor and support the implementation of the corporate strategy, the Company’s strategic realignment toward oncology, and the associated transformation process in the best possible manner in the future. The two additional seats on the Supervisory Board are to be filled by the election of Dr. Susanne Schaffert and Prof. Dr. Iris Loew-Friedrich, as proposed under Agenda Item 8 of the Annual General Meeting.
The Management Board and the Supervisory Board therefore propose the following resolution:
Section 9 (1) of the Company’s Articles of Association is repealed and reworded as follows:
(1)    The Supervisory Board consists of eight members.”
The currently valid Articles of Association are available on our website at
https://investors.biontech.de/agm/agm-2026
and will also be available there during the Annual General Meeting.
8.Resolution on Elections to the Supervisory Board
Currently, pursuant to article 40 para. 2 and 3 of the SE Regulation, section 17 para. 1, second sentence of the SEAG, and section 9 para. 1 of the Articles of Association of BioNTech SE, the Supervisory Board of BioNTech SE consists of six members elected by the Annual General Meeting. Upon the effective date of the amendment to section 9 para. 1 of the Articles of Association proposed under Agenda Item 7 of this Annual General Meeting, the number of Supervisory Board members will increase from six to eight; the Supervisory Board of the Company will then, in accordance with article 40 para. 2 and 3 of the SE Regulation, section 17 para. 1 sentence 2 of the SEAG, and
4
Germany 17275785.16


section 9 para. 1 of the Articles of Association of the Company, consist of eight members elected by the Annual General Meeting.
Upon the conclusion of the Annual General Meeting on May 15, 2026, the terms of office of Mr. Helmut Jeggle, Prof. Dr. Anja Morawietz, and Prof. Dr. Rudolf Staudigl will expire. It is therefore necessary for the Annual General Meeting to elect three of the current six members of the Supervisory Board in a regular election. In addition, for the period beginning upon the effective date of the amendment to the Articles of Association proposed under Agenda Item 7 and the resulting expansion of the Supervisory Board to eight members, two additional members are to be elected to the Company’s Supervisory Board. A total of five Supervisory Board members is therefore to be elected by the Annual General Meeting on May 15, 2026.
To ensure the sustainable and successful implementation of the Company’s objectives, a high degree of continuity in the work of the Supervisory Board must be maintained beyond 2026. For this reason, the current Chairman of the Supervisory Board, Mr. Helmut Jeggle, as well as the two Supervisory Board members, Prof. Dr. Anja Morawietz and Prof. Dr. Rudolf Staudigl, are to be reappointed by the Annual General Meeting. Mr. Helmut Jeggle possesses, among other things, special expertise in management, sales, and marketing in the biotech industry, as well as in accounting, auditing, and controlling (including sustainability reporting), and has international experience in markets relevant to the Company. Prof. Dr. Anja Morawietz possesses particular expertise in areas such as accounting, auditing, and controlling (including sustainability reporting), as well as in compliance, internal control, and risk management. Prof. Dr. Rudolf Staudigl, possesses, among other things, special expertise in the areas of innovation as well as research and development, expertise in the leadership of large companies in particular in the areas of human resources and management, and international experience in the markets relevant to the Company. The proposed re-elections of Mr. Jeggle, Prof. Dr. Morawietz, and Prof. Dr. Staudigl are intended to ensure their continued participation on the Supervisory Board and the contribution of their expertise to the work of the Supervisory Board and its committees beyond the year 2026.
In the search for candidates for the two additional Supervisory Board members to be elected by the Annual General Meeting on May 15, 2026, the focus was on identifying candidates who, to the greatest extent possible, bring experience in the fields of oncology and commercialization (product launches) as well as in the markets relevant to the Company, and who can demonstrate expertise in clinical development and, more generally, in the natural sciences.
Against this background and following a thorough review of the candidates and upon the recommendation of the Compensation, Nomination and Corporate Governance Committee, the Supervisory Board has recommended Dr. Susanne Schaffert and Prof. Dr. Iris Loew-Friedrich, who will accordingly be proposed for election at the Annual General Meeting. Dr. Susanne Schaffert possesses particular expertise in the field of oncology as well as in sales and commercialization, particularly in product launches, and has
5
Germany 17275785.16


knowledge in the areas of innovation, research and development, and management; she also has international experience in the markets relevant to the Company. Prof. Dr. Iris Loew-Friedrich possesses particular expertise in the field of clinical development and generally in the scientific and medical sectors, as well as knowledge in the areas of sales and commercialization, management, and innovation, and international experience in the markets relevant to the Company. In particular, both candidates possess a deep understanding of the biopharmaceutical market and the Company’s key clinical development phases, and thus effectively complement the Supervisory Board’s established expertise profile.
The re-elections of Mr. Helmut Jeggle, Prof. Dr. Anja Morawietz, and Prof. Dr. Rudolf Staudigl are to take place for a term of office beginning at the close of the Annual General Meeting on May 15, 2026, and ending until the close of the Annual General Meeting that resolves on the discharge for the 2029 financial year .
The elections of Dr. Susanne Schaffert and Prof. Dr. Iris Loew-Friedrich are to be for a term of office beginning upon the entry of the amendment to the Articles of Association proposed under Agenda Item 7 in the Company’s Commercial Register and ending at the close of the Annual General Meeting that resolves on the discharge for the 2026 financial year .
Against this background, the Supervisory Board proposes that the individuals listed below in sections 8.1 through 8.3 be elected as members of the Supervisory Board, effective from the close of the Annual General Meeting on May 15, 2026, until the close of the Annual General Meeting that resolves on the discharge of liability for the 2029 financial year :
8.1    Mr. Helmut Jeggle, resident of Holzkirchen, managing partner of Salvia GmbH and entrepreneurial venture capital investor,
8.2    Prof. Dr. Anja Morawietz, residing in Frankfurt am Main, Professor of External Accounting and General Business Administration at the Georg Simon Ohm University of Applied Sciences in Nuremberg, and
8.3    Prof. Dr. Rudolf Staudigl, residing in Burghausen, independent management consultant.
Furthermore, the Supervisory Board proposes that the persons listed below under items 8.4 and 8.5 be entered in the Commercial Register as members of the Supervisory Board, effective from the date of entry of the amendment to the Company’s Articles of Association proposed under Agenda item 7 of the Annual General Meeting of May 15, 2026, until the conclusion of the Annual General Meeting that decides on the discharge for the 2028 financial year :
8.4    Dr. Susanne Schaffert, resident of Neumarkt, member of various supervisory boards, and
6
Germany 17275785.16


8.5    Prof. Dr. Iris Loew-Friedrich, residing in Ratingen, member of various supervisory boards
The elections are to be conducted as individual elections.
The Supervisory Board’s nominations are based on corresponding proposals from the Compensation, Nomination, and Corporate Governance Committee and take into account the objectives adopted by the Supervisory Board regarding its composition as well as the competency profile and diversity concept developed by the Supervisory Board for the entire body.
Mr. Helmut Jeggle is a member of the Supervisory Board of 4SC AG, Planegg, AiCuris Anti-infective Cures AG, Wuppertal, and tonies SE, Luxembourg, as well as Chairman of the Advisory Board of CorTec GmbH, Freiburg, a non-executive member of the Board of Directors of Bambusa Therapeutics Inc., Boston, USA, and a non-executive member of the Board of Directors of Solaris Pharma Corporation, Bridgewater, USA. Prof. Dr. Rudolf Staudigl is Chairman of the Supervisory Board of Zadient Technologies SAS, Sainte-Hélène-du-Lac, France, and Vice Chairman of the Supervisory Board of Groz-Beckert KG, Albstadt. Dr. Susanne Schaffert is Chairwoman of the Supervisory Board of Merck Healthcare KGaA, Darmstadt, and a member of the Supervisory Board of Merck KGaA, Darmstadt, and of Merck Life Science KGaA, Darmstadt; she is also a member of the Shareholders’ Council of E. Merck KG, Darmstadt, the Board of Directors of Novo Holdings A/S, Hellerup, Denmark, the Board of Directors of ARTBio Inc., Cambridge, USA, and the Board of Directors of Incyte Corporation, Wilmington, USA (until April 15, 2026). Prof. Dr. Iris Loew-Friedrich is Chair of the Supervisory Board of Evotec SE, Hamburg, and a member of the Supervisory Board of Fresenius SE & Co. KGaA, Bad Homburg; she is also a member of the Board of Directors of Swedish Orphan Biovitrum AB (SOBI), Stockholm, Sweden; the Board of Directors of Satellos Bioscience Inc., Toronto, Canada; the Board of Directors of Financière de Tubize S.A., Brussels, Belgium; and the Board of Directors of Zealand Pharma A/S, Søborg, Denmark. Furthermore, the proposed candidates do not serve on any other statutory supervisory board or comparable domestic or foreign supervisory body of commercial enterprises within the meaning of section 125 para. 1 sentence 5 of the AktG. Prof. Dr. Iris Loew-Friedrich is currently in advanced discussions regarding a position on the Board of Directors of Zealand Pharma A/S, Søborg, Denmark.
In the Supervisory Board’s assessment, the proposed candidates are to be regarded as independent of the Company and the Management Board within the meaning of the German Corporate Governance Code (“DCGK”). In the Supervisory Board’s view, this also applies to Mr. Helmut Jeggle, who is proposed for reelection and has been a member of the Supervisory Board for more than twelve years. In this respect, the length of service is only one of several indicators that, according to the DCGK, should be taken into account when assessing the independence of Supervisory Board members. Furthermore, Mr. Jeggle’s previous work on the Supervisory Board and its committees has demonstrated that, in part due to his many years of experience, he continues to maintain
7
Germany 17275785.16


the professional distance from the Company and its Management Board necessary for the independent performance of his duties. Against this background, and given his existing financial independence from the Company and the absence of any other matters that could give rise to potential conflicts of interest, the Supervisory Board has concluded, after the necessary overall assessment, that Mr. Jeggle continues to be regarded as independent of the Company and the Management Board, without the length of his previous tenure on the Supervisory Board precluding this. In the Supervisory Board’s assessment, it is also in the Company’s interest to continue to benefit from Mr. Jeggle’s knowledge of the Company and its industry, his extensive expertise in the fields of finance, economics, science, and capital markets, as well as his many years of experience as a member of the Supervisory Board of the Company. The two candidates newly proposed for election, are also considered independent by the Supervisory Board. Dr. Schaffert has a consulting agreement with the Company on standard market terms for consulting services in areas including commercialization and market access, as well as commercial matters in the field of research and development. This consulting agreement is to be terminated upon the effective date of Dr. Schaffert’s election to the Company’s Supervisory Board, as Dr. Schaffert will contribute her expertise to the Company in her capacity as a member of the Supervisory Board from that point onward. In order to be able to draw on the additional expertise of Prof. Dr. Loew-Friedrich - which is of particular significance to the Company - even before her appointment as a member of the Supervisory Board (which will only take effect upon entry of the amendment to the Articles of Association proposed under Agenda item 7 in the Commercial Register), a consulting agreement was also concluded with Prof. Dr. Loew-Friedrich on March 24, 2026, on standard market terms, the purpose of which is to provide support and advice to the Supervisory Board and the Product Committee; the consulting agreement with Prof. Dr. Loew-Friedrich is also to terminate upon the effective date of her election to the Company’s Supervisory Board. Neither of these agreements constitutes a “material” business relationship within the meaning of the DCGK. The consulting agreement with Dr. Loew-Friedrich will be in effect for only a very short transitional period of a few months, and the agreement with Dr. Schaffert has only been in place since September 2023 and does not create any potential for economic influence or, even less, a relationship of dependency. Both consulting agreements will terminate upon the candidates’ assumption of office and are therefore not likely to impair the candidates’ judgment in the long term as a result of any conflicts of interest that might be feared. Furthermore, in the opinion of the Supervisory Board, there are no personal or business relationships between the proposed candidates and the Company or its group companies, the Company’s governing bodies, or a shareholder holding a significant stake in the Company within the meaning of Recommendation C.13 of the DCGK that an objectively judging shareholder would consider decisive for his or her voting decision.
Prof. Dr. Anja Morawietz, Prof. Dr. Rudolf Staudigl and Mr. Helmut Jeggle possess expertise in both accounting and auditing.

The Supervisory Board has verified that all candidates are able to commit the time required to fulfill their duties as members of the Company’s Supervisory Board. All candidates are familiar with the sector in which the Company operates.
Further information on the candidates, in particular their résumés, which also provide details on the candidates’ relevant knowledge, skills, and professional experience, is available on the company’s website at
https://investors.biontech.de/agm/agm-2026
and will also be available there during the Annual General Meeting.
9.Resolution on the amendment of Section 16 para. 5 of the Articles of Association to reauthorize the Management Board to provide for the holding of a virtual Annual General Meeting
The Company’s Annual General Meeting on May 25, 2023, authorized the Management Board to arrange for the Annual General Meeting to be held without the physical presence of shareholders or their proxies at the venue of the Annual General Meeting (virtual Annual General Meeting). The authorization granted to the Management Board is valid for a period of three years following the entry of the corresponding provision in the Articles of Association in the Commercial Register. It therefore expires on June 29, 2026, and thus before the Annual General Meeting scheduled for 2027.
The Company’s Management Board has made use of the aforementioned authorization on several occasions in recent years and has held the Company’s Annual General Meeting as a virtual meeting since 2024. In doing so, the Company - like many other companies - has consistently had positive experiences with the virtual format, which has established itself in recent years as a modern and sustainable meeting format and has since become a widely accepted standard. The Management Board and Supervisory Board are of the overall opinion that the virtual format has proven to be an efficient and legally compliant alternative to in-person meetings for the Company. In recent years, the Company has structured its virtual Annual General Meetings in such a way that the key advantages of an in-person meeting are transferred to the digital format, and shareholders are granted full rights to speak, ask questions, and submit motions. Shareholders and their representatives thus have the opportunity to exercise these rights without the expense of travel, thereby doing so efficiently and in a resource-efficient manner. International shareholders in particular benefit from this option, which makes the virtual format especially attractive for the Company as an internationally oriented enterprise whose ADSs are also listed on the U.S. NASDAQ stock exchange. The Company’s past virtual Annual General Meetings proceeded without any technical or organizational restrictions on the Company’s part.
In light of these positive experiences, the Management Board and Supervisory Board believe that the Company should continue to have the option of holding Annual General
9
Germany 17275785.16


Meetings virtually. However, since there may also be Annual General Meetings where an in-person format appears more appropriate, the authorization - as has been the case to date - should again be structured in such a way that it enables the Management Board to flexibly decide on the meeting format in advance of each Annual General Meeting.
A corresponding new authorization for the Management Board is therefore to be adopted, and section 16 para. 5 of the Articles of Association - which currently contains the existing authorization to hold virtual general meetings - is to be amended accordingly. The new authorization is not intended to fully utilize the maximum term of five years provided for by law, but rather to apply for a period of two years following the registration of the amendment to the Articles of Association. Due to this narrow time limit on the authorization, the Company’s shareholders will thus be able to decide again in the near future whether to grant the Management Board authorization to hold virtual Annual General Meetings in the future as well.
For future Annual General Meetings as well, the Management Board will decide, exercising due discretion and taking into account the circumstances of the specific case, in the best interests of the Company, whether to make use of the proposed authorization and hold an Annual General Meeting in a virtual format. In doing so, it will continue to make its decision with due consideration of the interests of the shareholders, taking into account, in particular, the goal of the broadest and most flexible shareholder participation possible, as well as financial aspects, planning certainty, the reach of the format, and sustainability considerations. Shareholder rights will be fully safeguarded in accordance with legal requirements, regardless of the format of the Annual General Meeting.
Against this background, the Management Board and the Supervisory Board propose the following resolution:
Section 16 para. 5 of the Company’s Articles of Association is repealed and reworded as follows:
(5)     The Management Board is authorized to provide for the Annual General Meeting to be held without the physical presence of shareholders or their proxies at the venue of the Annual General Meeting (virtual Annual General Meeting). The authorization shall apply to the holding of virtual shareholder’s meetings for a period of two years after the entry of this provision of the Articles of Association in the Commercial Register of the Company.”
The currently valid Articles of Association are available on our website at
https://investors.biontech.de/agm/agm-2026
and will also be available there during the Annual General Meeting.

10.Resolution on the cancellation of the existing Authorized Capital 2025 and the creation of a new Authorized Capital 2026 with the option to exclude subscription rights, as well as the corresponding amendment to the Articles of Association
The authorization granted to the Management Board by the Annual General Meeting on May 16, 2025, under Agenda Item 7, to increase the Company’s share capital, with the approval of the Supervisory Board, on one or more occasions by a total of up to EUR 124,276,100 through the issuance of up to 124,276,100 new registered no-par value shares in exchange for cash and/or non-cash contributions (Authorized Capital 2025) has been partially utilized and currently remains in the amount of EUR 113,800,813. In order to continue to provide the Company with the necessary flexibility in its financing beyond this, the existing authorization, to the extent it has not been utilized, is now to be revoked and replaced by a new Authorized Capital 2026 in the amount of EUR 129,513,743; this corresponds to 50% of the current share capital. In all other respects, the 2026 Authorized Capital is to correspond in substance to the previous 2025 Authorized Capital 2025.
Against this background, the Management Board and Supervisory Board propose the following resolution:
a)The Authorized Capital 2025 established by the Annual General Meeting on May 16, 2025, under Agenda Item 7, pursuant to section 4 para. 5 of the Articles of Association shall, to the extent not yet utilized, be cancelled in accordance with the further provisions of subparagraph (d) below and revoked with effect as of the date of entry in the Commercial Register specified therein.
b)The Management Board is authorized, with the approval of the Supervisory Board, to increase the Company’s share capital on one or more occasions in the period up to May 15, 2030, by a total of up to EUR 129,513,743 by issuing up to 129,513,743 new no-par value registered shares in return for cash and/or non-cash contributions (Authorized Capital 2026). The Management Board is authorized, with the approval of the Supervisory Board, to determine the further content of the share rights and the conditions of the share issue.
Shareholders must generally be granted subscription rights. The shares may also be acquired by one or more credit institutions, securities institutions or other companies within the meaning of section 186 (5) sentence 1 AktG specified by the Management Board with the obligation to offer them to the Company's shareholders for subscription (indirect subscription right).

However, the Management Board is authorized, with the approval of the Supervisory Board, to exclude shareholders' subscription rights for one or more capital increases within the scope of the Authorized Capital 2026:
to exclude fractional amounts from the subscription rights;
11
Germany 17275785.16


in the case of a capital increase against cash contributions, if the issue price of the new shares is not significantly lower than the market price; the market price is also deemed to be the price of one American Depositary Share of the Company (“ADS”) listed on the NASDAQ stock exchange multiplied by the number of ADSs representing one share. The total number of shares issued in exercise of this authorization to exclude subscription rights may not exceed 10% of the share capital, neither at the time this authorization becomes effective nor - if this value is lower - at the time this authorization is exercised. Shares or ADSs issued or sold during the term of this authorization in direct or analogous application of section 186 (3) sentence 4 AktG with the exclusion of subscription rights are to be counted towards this limit of 10% of the share capital. Furthermore, shares or ADSs issued or to be issued to service bonds with option and/or conversion rights or option and/or conversion obligations shall be counted towards this limit of 10% of the share capital, provided that the bonds are issued during the term of this authorization in corresponding application of section 186 (3) sentence 4 AktG with the exclusion of subscription rights. The above issue limitation shall apply to ADSs, provided that the number of ADSs is to be divided by the number of ADSs representing one share;

in the event of a capital increase against contributions in kind, in particular for the issuance of shares as part of business combinations and the acquisition of companies, parts of companies and interests in companies or other assets or claims to the acquisition of assets including receivables from the Company and its group companies as well as license or industrial property rights;

to service option or conversion rights or obligations arising from bonds issued or to be issued by the Company and/or companies in which the Company holds a direct or indirect majority interest;

to the extent necessary to grant holders or creditors of bonds with option or conversion rights or obligations issued or to be issued by the Company and/or companies in which the Company holds a direct or indirect majority interest a subscription right to new shares to the extent to which they would be entitled after exercising the option or conversion rights or after fulfilling the option or conversion obligations;
to implement a scrip dividend, whereby shareholders are offered the option of contributing their dividend entitlement (in whole or in part) to the Company as a contribution in kind in return for the issuance of new shares;
if the new shares are issued as part of an incentive program and/or as share-based compensation to members of the Company’s Management Board, members of the management of companies affiliated with the Company within the meaning of sections 15 et seq. AktG or employees of the Company or of companies affiliated with the Company within the meaning of sections 15 et seq. AktG; restrictions
12
Germany 17275785.16


relating to the shares issued may be agreed. If shares are to be issued to members of the Management Board, the Company’s Supervisory Board decides the allocation in accordance with the allocation of responsibilities under stock corporation law.
The total number of new shares issued from the Authorized Capital 2026 with the exclusion of subscription rights may not exceed 10% of the share capital, either at the time this authorization becomes effective or - if this value is lower - at the time it is exercised. The aforementioned 10% limit shall include (i) those shares or ADSs that are issued or sold during the term of this authorization on the basis of other authorizations with the exclusion of subscription rights, with the exception of treasury shares or ADSs used in accordance with para. c) (iv), (v) or (vi) of the resolution on Agenda item 10 of the Annual General Meeting on May 17, 2024, also in conjunction with para. f) of the resolution on Agenda item 11 of the Annual General Meeting on May 17, 2024, as well as (ii) those shares that are issued or are to be issued from conditional capital to service bonds with option and/or conversion rights or option and/or conversion obligations, provided that the bonds are issued during the term of this authorization under exclusion of subscription rights. The above issue limitation applies to ADSs, provided that the number of ADSs is to be divided by the number of ADSs representing one share.
The Supervisory Board is authorized to amend the Articles of Association following the full or partial implementation of the capital increase from the Authorized Capital 2026 in accordance with the scope of the capital increase from the Authorized Capital 2026 or following the expiry of the authorization period.
c)Section 4 para. 5 of the Articles of Association of the Company is repealed and reworded as follows:
(5)    The Management Board is authorized, with the approval of the Supervisory Board, to increase the Company’s share capital on one or more occasions in the period up to May 15, 2030, by a total of up to EUR 129,513,743 by issuing up to 129,513,743 new no-par value registered shares in return for cash and/or non-cash contributions (Authorized Capital 2026). The Management Board is authorized, with the approval of the Supervisory Board, to determine the further content of the share rights and the conditions of the share issue.
Shareholders must generally be granted subscription rights. The shares may also be acquired by one or more credit institutions, securities institutions or other companies within the meaning of section 186 (5) sentence 1 AktG specified by the Management Board with the obligation to offer them to the Company's shareholders for subscription (indirect subscription right).

11.Resolution on the approval of the conclusion of a domination and profit and loss transfer agreement between BioNTech SE and BioNTech Discovery GmbH
A domination and profit and loss transfer agreement is to be concluded between the Company and its wholly-owned subsidiary BioNTech Discovery GmbH (hereinafter also referred to as the “Subsidiary”).
For the domination and profit and loss transfer agreement to be effective, it requires the approval of the Company’s Annual General Meeting and the Subsidiary’s shareholders’ meeting, as well as registration in the Subsidiary’s Commercial register. It is intended that, shortly after the Company’s Annual General Meeting, the Subsidiary’s shareholders’ meeting will grant its approval and the agreement will be concluded.
The purpose of entering into this agreement is to establish a corporate tax and trade tax group, which would allow profits generated at the level of the Subsidiary (as the group member) to be offset against any losses at the level of the parent company (as the group head).
The draft domination and profit and loss transfer agreement contains the following key provisions:
As a controlled entity, the Subsidiary places its management under the authority of the parent company, which is thereby entitled to issue instructions to the Subsidiary’s management. The management and representation of the Subsidiary remain the responsibility of its management.
16
Germany 17275785.16


As a controlled entity, the Subsidiary is obligated to transfer its profits to the parent company in accordance with section 301 AktG.
The Company, as the controlling entity, is obligated to offset any annual net loss of the Subsidiary arising during the term of the agreement. The provisions of section 302 of the AktG, as amended, apply to the assumption of losses.
The domination and profit and loss transfer agreement becomes effective upon entry in the Subsidiary’s Commercial Register, whereby the agreement applies retroactively from the beginning of the Subsidiary’s financial year in which the domination and profit and loss transfer agreement was entered in the Subsidiary’s Commercial Register. An exception applies in this regard to the authority to issue instructions described above, which does not apply retroactively but only from the date of entry of the domination and profit and loss transfer agreement in the Subsidiary’s Commercial Register.
The domination and profit and loss transfer agreement is concluded for a fixed term of five years from the start of the Subsidiary’s financial year in which the agreement is entered in the Subsidiary’s Commercial Register . The agreement shall be automatically renewed for one year at a time, with the same right of termination, unless terminated by either party at least six months prior to its expiration. If the end of the term or a renewal does not coincide with the end of a financial year of the Subsidiary, the term shall be extended until the end of the then-current financial year.
In addition, there is a right to terminate the agreement extraordinarily without notice for good cause. Good cause entitling both the controlling entity and the controlled entity to terminate the agreement includes, in particular - but not exclusively - the sale of the shares in the controlled entity or the contribution of the controlling interest by the controlling entity, the merger, demerger, or liquidation of the controlling entity or the controlled entity, or if the controlling entity no longer holds the majority of voting rights from the shares in the controlled entity.
The domination and profit and loss transfer agreement may also be terminated by mutual agreement in lieu of termination.
If the validity of the domination and profit and loss transfer agreement or its proper implementation is not recognized for tax purposes, or is not fully recognized, during the five-year period, the five-year period shall not commence until the first day of the Subsidiary’s financial year following the year in which the conditions for tax recognition of the agreement’s validity or its proper performance were not yet met.
The domination and profit and loss transfer agreement does not provide for any compensation or severance claims.
With regard to the domination and profit and loss transfer agreement between the Company as the controlling entity and BioNTech Discovery GmbH as the controlled entity, no contract review was required pursuant to section 293b para. 1 AktG due to the
17
Germany 17275785.16


ownership structure, as the Company holds all shares in BioNTech Discovery GmbH and will continue to hold them at the time the agreement is concluded.
The Management Board and Supervisory Board propose the following resolution:
The Annual General Meeting approves the conclusion of the domination and profit and loss transfer agreement between the Company and BioNTech Discovery GmbH, a limited liability company with its registered office in Mainz, entered in the Commercial Register of the Mainz Local Court under HRB 53731.
The following documents are available on our website at
https://investors.biontech.de/agm/agm-2026
and will also be available there during the Annual General Meeting:
the draft domination and profit and loss transfer agreement between the Company and the Subsidiary;
the annual financial statements and consolidated financial statements of the Company for the 2023, 2024, and 2025 financial years, as well as the combined management reports for the Company and the Group for the 2023, 2024, and 2025 financial years, and the annual financial statements of BioNTech Discovery GmbH for the short financial year from May 27, 2025, to December 31, 2025 (no further annual financial statements are currently available for BioNTech Discovery GmbH, which was first entered in the Commercial Register on May 27, 2025); and
the joint report of the Company’s Management Board and the management of the Subsidiary prepared in accordance with section 293a AktG.

II.Further Information and Notes
1.Implementation as virtual Annual General Meeting, Broadcast, Investor Portal
On the basis of section 118a AktG in conjunction with section 16 para. 5 of the Articles of Association, the Management Board has decided to hold the Annual General Meeting as a virtual Annual General Meeting without the physical presence of shareholders or their proxies at the venue of the Annual General Meeting. Shareholders or their proxies will exercise their voting rights exclusively by means of electronic absentee voting or by granting power of attorney and issuing instructions to the proxies appointed by the Company. The physical presence of shareholders or their proxies (with the exception of the proxies appointed by the Company) at the venue of the Annual General Meeting is excluded.
The virtual Annual General Meeting will take place on Friday, May 15, 2026, starting at 2:00 p.m. (CEST) and will be available live in video and audio format for our shareholders entered in the share register and duly registered and their proxies in our password-protected Investor Portal, which can be accessed via our website
https://investors.biontech.de/agm/agm-2026
In addition, the entire Annual General Meeting is also freely accessible outside the Investor Portal on our aforementioned website.
When using the Investor Portal during the virtual Annual General Meeting on Friday, May 15, 2026, shareholders or their proxies will be connected electronically to the virtual Annual General Meeting and can exercise their shareholder rights via the Investor Portal. Shareholders who are duly registered and entered in the share register - in person or by proxy - can use the Investor Portal to exercise their voting rights, exercise their right to speak and request information, raise objections for the record and submit statements prior to the meeting, among other things.
The individual access data for the Investor Portal will be sent to shareholders who are entered in the Company’s share register no later than Friday, April 24, 2026, 0:00 hours (CEST), together with the registration documents for the Annual General Meeting.
The use of the Investor Portal by an authorized representative requires that the authorized representative receives the corresponding access data from the principal, unless the access data has been sent directly to the authorized representative. Details can be found in the following sections.
We kindly refer our ADS holders to the section “ADS holders" below and to the separate document “Information for ADS holders” on our website.
2.Requirements for attending the Annual General Meeting and exercising voting rights
19
Germany 17275785.16


In accordance with section 15 (2) of the Articles of Association, shareholders entered in the share register are entitled to participate in the Annual General Meeting (i.e., to connect to the Annual General Meeting electronically) and to exercise their voting rights, provided they have registered in good time. The registration deadline is Friday, May 8, 2026, 24:00 hours (CEST).
The registration must be in German or English and must be received by the Company at the following address by Friday, May 8, 2026, 24:00 hours (CEST) at the latest:
BioNTech SE
c/o Computershare Operations Center
80249 Munich
Germany
Email: anmeldestelle@computershare.de
or electronically within the aforementioned registration period using the password-protected Investor Portal on the following website of the Company:
https://investors.biontech.de/agm/agm-2026
Alternatively, registration may be submitted within the above registration period via intermediaries in accordance with section 67c para. 1 and 2, sentence 3 AktG in conjunction with article 2 para. 1 and 3 and article 9 para. 4 of the Implementing Regulation (EU) 2018/1212 to the following SWIFT address:
SWIFT: CMDHDEMMXXX; instructions in accordance with ISO 20022;
Authorization via SWIFT Relationship Management Application (RMA) required.
In relation to the Company, rights and obligations arising from shares pursuant to section 67 para. 2 sentence 1 AktG only exist for and against those entered in the Company’s share register. The entitlement to participate in the Annual General Meeting and the scope of voting rights are determined exclusively by the entry status in the share register on the day of the Annual General Meeting. After the end of the registration deadline, i.e. after Friday, May 8, 2026, at 12:00 a.m. (CEST), no changes will be made to the share register until the end of the Annual General Meeting for technical reasons. Therefore, the entry status of the share register on the day of the Annual General Meeting corresponds to the status on Friday, May 8, 2026, at 12:00 a.m. (CEST) (“Technical Record Date”). Shares are not blocked by registering for the Annual General Meeting (no lock-up period). Shareholders can therefore continue to freely dispose of their shares even after registration. However, purchasers of shares whose applications for transfer are received by the Company after Friday, May 8, 2026, at 12:00 a.m. (CEST), cannot exercise any meeting-related rights from these shares unless they have themselves authorized to do so or are authorized to exercise such rights.
20
Germany 17275785.16


Shareholders who are entered in the Company’s share register by no later than Friday, April 24, 2026, 0:00 hours (CEST), will be sent registration documents for the Annual General Meeting, which also contain the individual access data required to use the password-protected Investor Portal. If the registration documents with the access data are not sent to you unsolicited - in particular because you are not entered in the Company's share register until after Friday, April 24, 2026, at 0:00 hours (CEST) - we will be happy to send them to you upon request.
3.Procedure for voting

c.Procedure for voting by proxies appointed by the Company
In order to exercise voting rights at the Annual General Meeting, the Company also offers shareholders and their proxies the option of authorizing proxies appointed by the Company who are bound by instructions. In this case, the above-mentioned requirements for attending the Annual General Meeting and exercising voting rights must also be met.
21

Without instructions, the proxies appointed by the Company are not authorized to exercise voting rights. The proxies appointed by the Company do not accept authorizations to file objections to resolutions of the Annual General Meeting, to exercise the right to speak and request information, to submit statements or to submit motions, either prior to or during the virtual Annual General Meeting.

22
Germany 17275785.16


The granting of powers of attorney and instructions to proxies appointed by the Company is also possible via this channel during the Annual General Meeting on May 15, 2026, until the start of voting. Any powers of attorney and instructions to proxies previously granted may also be amended or revoked via the Investor Portal during the Annual General Meeting until the start of voting.
d.Procedure for voting by other authorized representatives

Shareholders may also have their voting rights exercised by another proxy, including an intermediary, a shareholders’ association, a proxy advisor or another institution or person equivalent to intermediaries pursuant to section 135 para. 8 AktG. In this case, the above-mentioned requirements for attending the Annual General Meeting and exercising voting rights must also be met.
The granting and revocation of the power of attorney and proof of authorization vis-à-vis the Company must be in text form (section 126b BGB).
Proof that authorization has been granted can be provided by sending proof in text form by post or e-mail to the address below:
BioNTech SE
c/o Computershare Operations Center
80249 Munich
Germany
Email: anmeldestelle@computershare.de
The above transmission channels are also available if the proxy is to be granted in text form by declaration to the Company; in this case, separate proof of the granting of the proxy is not required. The revocation of a proxy already granted can also be declared directly to the Company in text form using the above-mentioned transmission channels. For organizational reasons, the granting of the proxy, its proof or revocation by one of the above-mentioned transmission channels must be received by the Company by Thursday, May 14, 2026, at 24:00 hours (CEST).
The granting of a power of attorney and its revocation by declaration to the Company can also be transmitted to the Company by intermediaries in accordance with section 67c para 1 and 2, third sentence AktG in conjunction with article 2 para. 1 and 3 and article 9 para. 4 of the Implementing Regulation (EU) 2018/1212 by no later than Thursday, May 14, 2026, 12:00 a.m. (CEST) (time of receipt) to the following SWIFT address:

23
Germany 17275785.16


Furthermore, the granting and revocation of the power of attorney may also be made electronically on the day of the Annual General Meeting by submitting a declaration to the Company via the Investor Portal.
Special rules may apply to the authorization of intermediaries, shareholders’ associations, voting rights advisors and other persons or institutions equivalent to intermediaries pursuant to section 135 para. 8 AktG. Section 135 AktG stipulates, among other things, that the power of attorney must be granted to a specific proxy and must be verifiably recorded by the proxy. The proxy declaration must also be complete and may only contain declarations related to the exercise of voting rights. Shareholders who wish to authorize an intermediary, a shareholders’ association, a proxy advisor or another person or institution with equivalent status pursuant to section 135 para. 8 AktG are therefore requested to consult with the proxy holder in good time regarding the procedure for granting power of attorney and the form of power of attorney that may be required. Intermediaries, shareholders’ associations, proxy advisors and other persons or institutions deemed equivalent to intermediaries pursuant to section 135 para. 8 AktG may only exercise voting rights for registered shares that do not belong to them, but for which they are entered in the share register as the holder, on the basis of an authorization.
A form that can be used to appoint a proxy will be sent to shareholders who are entered in the share register by no later than Friday, April 24, 2026, 0:00 hours (CEST), together with the registration documents for the Annual General Meeting. A proxy authorization form can also be downloaded from the Company’s website at

Authorized representatives cannot physically attend the Annual General Meeting either. They can only exercise the voting rights for shareholders they represent by means of electronic voting or by granting (sub)authorizations and instructions to the proxies appointed by the Company.
e.Further information on the exercise of voting rights
If the voting right is exercised in due time both by electronic vote via the Investor Portal and by proxy with instructions to the Company’s proxies, the vote cast by electronic vote via the Investor Portal will always be given priority, regardless of the time of receipt.
If differing authorizations with instructions are received by the Company’s proxies by different means of transmission by the deadline, they will be considered in the following order regardless of the time of receipt: 1. via the Investor Portal, 2. in accordance with section 67c para. 1 and 2 sentence 3 AktG in conjunction with article 2 para. 1 and 3 and article 9 para. 4 of Implementing Regulation (EU) 2018/1212, 3. by e-mail, 4. declarations sent by post. Information on issuing authorizations and instructions to the proxies appointed by the Company at can also be found on the forms provided for this purpose.
24
