To the shareholders of VectivBio Holding AG

Invitation to the

2023 Annual General Meeting

Date and Time: Thursday, June 1, 2023, at 3:00 p.m. CEST / 9:00 a.m. EDT (doors open at 2:30 p.m. CEST / 8:30 a.m. EDT)

Location: Memox (meeting room “Small Space”), Elisabethenstrasse 15, 4051 Basel, Switzerland

Dear Shareholders,

We are pleased to invite you to the 2023 Annual General Meeting of VectivBio Holding AG (the Company), which will be held on Thursday, June 1, 2023, at Memox (meeting room “Small Space”), Elisabethenstrasse 15, 4051 Basel, Switzerland, and start at 3:00 p.m. CEST / 9:00 a.m. EDT (the 2023 Annual General Meeting).

The 2023 Annual General Meeting will be conducted in English. A record of the resolutions taken by the 2023 Annual General Meeting will be available after the 2023 Annual General Meeting on the Company’s website at ir.vectivbio.com/events-and-presentations.

2022 was a very good year for VectivBio as we made significant progress against our R&D and corporate objectives, despite the challenging biotech environment. With respect to R&D activities, we advanced our pivotal program for apraglutide in patients with short bowel syndrome with intestinal failure (SBS-IF). This includes the Phase 3 STARS study, where we completed enrollment of the colon-in-continuity (CIC) cohort. We also made significant progress with the Phase 2 STARS Nutrition study, the first-ever dedicated clinical study in the subset of SBS-IF patients with CIC where we reported positive interim data. We’ve also advanced our STARGAZE proof-of-concept study in acute Graft-versus-Disease (aGvHD).

Regarding our key corporate activities, last year we strengthened our financial position through a combination of two equity raises, the establishment of a loan facility and an important Japan licensing deal with Asahi Kasei Pharma. In total we gained access to up to $284 million in new funds and extended our cash runway to more than 12 months after our anticipated Phase 3 results. Looking ahead, we see tremendous momentum in 2023, with important upcoming data readouts expected throughout the year, and we continue to execute our comprehensive launch readiness plan, with the aim of realizing the full market potential of apraglutide in SBS-IF.

VectivBio is a team of industry veterans with a successful track record in rare diseases, deep scientific expertise and a relentless focus on the patient. Our purpose is to identify and develop therapeutics that are both transformational and tailored to patients’ needs, and we appreciate your ongoing support towards this pursuit.

Yours sincerely,
Thomas Woiwode	Luca Santarelli
Chairman of the Board of Directors	Chief Executive Officer and member of the
	Board of Directors

Additional information on the compensation system for the Board of Directors can be found in the 2022 Compensation Report.

Explanation by the Board of Directors

Under the new Swiss corporate law, which entered into force on January 1, 2023, the previously available “authorized share capital” has been replaced with the so-called “capital range”. As the former authorized share capital, the proposed capital range gives the Company the necessary flexibility to raise capital on the financial markets without having to convene another General Meeting, in order to support the Company’s growth plan and to be able to fund the Company’s research and clinical development programs and other strategic projects. Further information on the new Swiss corporate law can be found in section 1.1 of the annex to this invitation to the 2023 Annual General Meeting.

The proposed introduction of a capital range is subject to a qualified majority of two thirds of the votes of the shares represented at the General Meeting.

10. Increase of the Conditional Share Capital for Participation Programs

The Board of Directors proposes (i) that the Company’s conditional share capital for participation programs be increased by CHF 692,576.75 to the maximum amount of CHF 1,233,908.75, allowing the issuance of up to 24,678,175 registered shares with a par value of CHF 0.05 each, and, accordingly, to amend article 3b (Conditional Share Capital for Participation Programs), paragraph 1, of the Articles of Association and (ii) to introduce a new paragraph 4 to article 3b of the Articles of Association as follows (amendments are underlined):

1 Das Aktienkapital kann sich durch Ausgabe von höchstens 24’678’175 voll zu liberierenden Namenaktien im Nennwert von je CHF 0.05 um höchstens CHF 1’233’908.75 erhöhen durch Ausgabe von Rechten auf den Bezug neuer Aktien im Sinne von Artikel 653 Abs. 1 OR an Mitglieder des Verwaltungsrates, Mitglieder der Geschäftsleitung oder Arbeitnehmer, Beauftragte oder Berater der Gesellschaft und ihrer Konzerngesellschaften oder andere Personen, welche Dienstleistungen für die Gesellschaft oder ihre Konzerngesellschaften erbringen.

1 The share capital may be increased in an amount not to exceed CHF 1,233,908.75 through the issuance of up to 24,678,175 fully paid in registered shares with a par value of CHF 0.05 per share through the issuance of rights to subscribe for new shares within the meaning of article 653(1) CO to members of the Board of Directors, members of the Executive Committee or employees, contractors or consultants of the Company or its group companies, or other persons providing services to the Company or its group companies.

4 Die Erklärung über den Erwerb von Aktien gestützt auf diesen Artikel 3b hat auf diesen Artikel 3b hinzuweisen und in einer Form, die den Nachweis durch Text ermöglicht, zu erfolgen. Ein Verzicht auf ein Recht auf Erwerb von Aktien gestützt auf diesen Artikel 3b kann auch formlos oder durch Zeitablauf erfolgen; das gilt auch für den Verzicht auf die Ausübung und den Verfall dieses Rechts.

4 The declaration of acquisition of the shares based on this Article 3b shall refer to this Article 3b and be made in a form that allows proof by text. A waiver of the right to acquire shares based on this Article 3b may also occur informally or by lapse of time; this also applies to the waiver of the exercise and forfeiture of this right.

Paragraphs 2 and 3 of article 3b of the Articles of Association remain unchanged.

Explanation by the Board of Directors

The increase of the conditional share capital for participation programs will allow future equity grants to employees, directors and consultants to cover the projected mid-term needs. While in order to limit dilution of shareholders, the Company aims to net settle any exercised options or to use shares purchased on the market therefor, from an accounting perspective, it is important for the Company that all options that are outstanding or will be granted in the mid-term are fully covered by conditional share capital. The proposed addition of para. 4 addresses a new requirement under the revised Swiss corporate law.

This proposed amendment is subject to a qualified majority of two thirds of the votes of the shares represented at the General Meeting.

11. Amendments to the Articles of Association

Explanation by the Board of Directors

On June 19, 2020, the Swiss Parliament adopted a revision of the Swiss corporate law, which entered into force on January 1, 2023, subject to certain transitional provisions. Pursuant to the new corporate law, Swiss corporations are obliged to revise their corporate documents to comply with the new corporate law by the end of 2024.

Annex – Proposed Amendments to the Articles of Association (Agenda Item 11)

1. Overview

1.1 Introductory Remarks

On June 19, 2020, the Swiss Parliament adopted a revision of the Swiss corporate law (“Corporate Law Reform”), which entered into force on January 1, 2023, subject to certain transitional provisions. The Corporate Law Reform primarily aims at modernizing Swiss corporate law, strengthening shareholder rights and integrating the provisions of the Ordinance against Excessive Compensation in Listed Companies, which entered into force on January 1, 2014, in the Swiss Code of Obligations.

The new Swiss corporate law provides for a transitional period of two years during which corporations have to amend their Articles of Association and other regulations to reflect the changes in the law. Accordingly, the Board of Directors proposes to the shareholders to revise the Articles of Association at this General Meeting.

The proposed amendments to the Articles of Association are grouped by thematic categories and submitted to the General Meeting for approval under four separate agenda items. References in this overview are to the proposed revised Articles of Association. In case of discrepancies between the English and the German version of the Articles of Association, the German version shall prevail.

1.2 Share Certificates and Intermediated Securities, Share Register, Restrictions on Registration, Nominees

The proposed amendments to the Articles of Association are clarifications resulting from recent case law (article 4 para. 2) or prevailing practice (article 5 para. 1).

1.3 Shareholder Rights, General Meeting of Shareholders, Notices and Communications

The Corporate Law Reform expands the powers of the General Meeting. The Board of Directors proposes to update article 7 of the Articles of Association accordingly.

The revised corporate law further strengthens the rights of shareholders by lowering the threshold for the right to request an Extraordinary General Meeting from 10% to 5% of the share capital or votes. The Board of Directors proposes to reflect this change in article 8 para. 2 lit. c of the Articles of Association.

The proposed changes to articles 9 and 10 of the Articles of Association reflect the new corporate law and new possible forms of communication (article 9 para. 3), new requirements in connection with the invitation to a General Meeting (article 9 para. 4) and the new thresholds for the right to request that an item be included in the agenda of a General Meeting or that a proposal relating to an agenda item be included in the invitation to the General Meeting (article 10 para. 1).

The proposed changes to articles 13 and 24 of the Articles of Association reflect the new corporate law.

The revised law allows corporations to communicate also through electronic means. Accordingly, the Board of Directors proposes to revise article 34 of the Articles of Association to allow the Company to make use of the new flexibility when appropriate, in particular with regard to the use of electronic means.

1.4 Board of Directors, Compensation of the Executive Committee, Mandates Outside the Company

The proposed changes to articles 18, 19, 26, 27 and 29 of the Articles of Association reflect the new corporate law.

1.5 Jurisdiction Clause

The proposed introduction of a new article 35 to our Articles of Association is aimed at improving the legal certainty regarding the place of jurisdiction for any disputes arising out of or in connection with the corporate relationship, in particular in an international context. Further, the jurisdiction clause reflects the applicable rules under Swiss law (including the Swiss Federal Act on Private International Law) and the Lugano Convention and is also in line with the practice of other listed Swiss companies.

2. Proposed Revised Provisions of the Articles of Association

2.1 Agenda Item 11.1: Share Certificates and Intermediated Securities, Share Register, Restrictions on Registration, Nominees

The Board of Directors proposes to amend articles 4 and 5 of the Articles of Association as shown below:

Insbesondere hat der Aktionär keinen Anspruch auf die Verbriefung der Mitgliedschaft in einem Wertpapier. Jeder Aktionär kann jedoch von der Gesellschaft jederzeit die Ausstellung einer Bescheinigung über die von ihm gemäss Aktienbuch gehaltenen Namenaktien verlangen. Article 4   (Paragraph 1 unchanged)   ² A shareholder has no right to request a conversion of the registered shares issued in one form into another form. In particular, no shareholder has a right to request that its membership be certified in a security certificate. Each shareholder may, however, at any time request from the Company a written confirmation of the registered shares held by such shareholder, as reflected in the share register.

(Absatz 3 unverändert) Artikel 5 1 Die Gesellschaft oder ein von ihr beauftragter Dritter führt für die Namenaktien ein Aktienbuch, in welches die Eigentümer und Nutzniesser mit Name und Vorname (bei juristischen Personen die Firma), Adresse und Staatsangehörigkeit (bei juristischen Personen der Sitz) eingetragen werden. Wechselt eine im Aktienbuch eingetragene Person ihre KontaktdatenAdresse, so hat sie dies dem Aktienbuchführer mitzuteilen. Solange dies nicht geschehen ist, gelten alle brieflichen Mitteilungen der Gesellschaft an die im Aktienbuch eingetragenen Personen bzw. Zustellungsbevollmächtigten als rechtsgültig an die bisher im Aktienbuch eingetragenen KontaktdatenAdresse erfolgt.

(Paragraph 3 unchanged) Article 5 1 The Company shall maintain, itself or through a third party, a share register for the registered shares that lists the surname and name (the name of the company in case of a legal entity), the address and the nationality (the registered office in case of a legal entity) of the shareholders or usufructuaries. A person registered in the share register shall notify the share registrar of any change in contact informationaddress. Until such notification has occurred, all written communications from the Company to persons or authorized delivery agents registered in the share register shall be deemed to have validly been validly made if sent to the contact informationaddress previously recorded in the share register.
