I. VIRTUAL GENERAL MEETING WITHOUT PHYSICAL PRESENCE OF SHAREHOLDERS

For the protection of shareholders and other participants, the Executive Board has decided to make use of the legal regulations for holding a virtual Annual General Meeting in view of the current pandemic situation.

The Annual General Meeting of S&T AG on 6 May 2022 will be held as a "virtual general meeting" on the basis of section 1 para. 2 COVID-19-GesG, BGBl. I No. 16/2020 as amended by BGBl. I Nr. 246/2021 and COVID-19-GesV (BGBl. II 140/2020 as amended by BGBl. II Nr. 609/2021), taking into account the interests of the Company and the participants.

According to the decision of the Executive Board, this means that for reasons of health protection, shareholders and their representatives (with the exception of the special proxies pursuant to section 3 para. 4 COVID-19-GesV) cannot be physically present at the Annual General Meeting of S&T AG on 6 May 2022.

The Annual General Meeting takes place at the premises of the Euro Plaza conference venue, 1120 Vienna, Am Euro Platz 2, Euro Plaza Bauteil G, in the physical presence of the Chairwoman of the Supervisory Board, the Chairman of the Executive Board and other members of the Executive Board, a representative of the auditor and the Company's legal counsel, the certifying notary public and the four special proxies appointed by the Company.

The holding of the Annual General Meeting as a virtual General Meeting in accordance with COVID-19-GesV leads to modifications in the otherwise usual course of the Annual General Meeting as well as in the exercise of shareholders' rights.

The exercise of voting rights, the right to make motions and the right to raise objections are exclusively carried out by granting power of attorney and instructions to one of the four special proxies proposed by the Company in accordance with section 3 para. 4 COVID-19-GesV.

The right to information can be exercised in the virtual Annual General Meeting by the shareholders themselves by means of electronic communication, by sending questions in text form exclusively by e-mail directly to the Company's e-mail address fragen.snt@hauptversammlung.at, provided that the shareholders have submitted a deposit confirmation within the meaning of section 10a AktG in due time in accordance with item IV. and have authorised a special voting proxy in accordance with item V.

This is permitted under data protection law in view of the legal basis in section 3 para. 4 COVID-19-GesV.

Every shareholder - regardless of a specific shareholding - is entitled to submit motions for each item on the agenda in the virtual Annual General Meeting in accordance with COVID-19-GesG and COVID-19-GesV through his special proxy.

However, motions may only be transmitted to the special proxy authorized by the respective shareholder and submitted by the latter at the Annual General Meeting.

The point in time up to which instructions for the submission of motions to the special proxy are possible will be determined by the chairwoman in the course of the virtual Annual General Meeting.

The prerequisite for this is proof of the right to attend in accordance with item IV. of this convocation and the granting of a corresponding power of attorney to the special voting proxy in accordance with item V. of this convocation.
