I. VIRTUAL GENERAL MEETING WITHOUT PHYSICAL PRESENCE OF SHAREHOLDERS

1. Austrian Company COVID-19-Act ("COVID-19-GesG") and Austrian Company COVID-19-Regulation ("COVID-19-GesV")

For the protection of shareholders and other participants, the Management Board has decided to make use of the legal regulations for holding a virtual Annual General Meeting.

The Annual General Meeting of S&T AG on 8 June 2021 will be held on the basis of section 1 para. 2 COVID-19-GesG, BGBl. I No. 16/2020 as amended by BGBl. I Nr. 156/2020 and COVID-19-GesV (BGBl. II 140/2020 as amended by BGBl. II Nr. 616/2020), taking into account the interests of the Company and the participants.

According to the decision of the Management 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 8 June 2021.

The Annual General Meeting takes place at the Company´s premises at 1110 Vienna, Brehmstraße 10, in the physical presence of the Chairwoman of the Supervisory Board, the Chairman of the Management Board and other members of the Management 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.

2. Broadcast of the General Meeting via the internet

In accordance with section 3 para. 4 COVID-19-GesV in conjunction with section 102 para. 4 AktG, the Annual General Meeting is broadcasted completely in real time in sound and video via the internet.

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

All shareholders of the Company can follow the Annual General Meeting on 8 June 2021 from around 12:00 noon, Vienna time, using appropriate technical aids (e.g. computer, laptop, tablet or smartphone as well as internet connection with sufficient bandwidth for streaming videos) via the internet at www.snt.at respectively https://ir.snt.at/. No registration or login is required to follow the Annual General Meeting.

By broadcasting the Annual General Meeting via the internet, all shareholders can follow the course of the Annual General Meeting in real time via the broadcast in sound and vision and follow the presentation by the Management Board and the answers to shareholders' questions.

Please note that the live broadcast as a virtual Annual General Meeting does not allow remote participation (section 102 para. 3 no. 2 AktG) and remote voting (section 102 para. 3 no. 3 AktG and section 126 AktG) and that the transmission on the internet is not a two-way connection. The individual shareholder can therefore only follow the course of the Annual General Meeting.
