As of the date of this notice, the Company holds 380,208 own shares, for which voting rights are suspended by law.

RIGHT TO ATTEND AND VOTE AT THE MEETING

Pursuant to Article 83-sexies of the TUF and Article 16 of the Articles of Association, entitlement to attend the Meeting and exercise voting rights, which may occur only through the designated representative, is subject to the receipt by the Company of the communication issued by an authorized intermediary pursuant to the applicable regulations, which must be requested by each eligible party, confirming the ownership of the shares as per the evidence of their accounting records on the last trading day before the date of the Meeting (April 13, 2026 – record date).

The right to participate and vote remains valid if communications are received after the deadline, as long as they arrive before the start of the Meeting.

ADDITIONS TO THE AGENDA AND PROPOSAL OF NEW RESOLUTIONS UNDER ARTICLE 126-BIS, PARAGRAPH 1, PENULTIMATE SENTENCE, TUF AND UNDER ARTICLE 135-UNDECIES.1 PARAGRAPH 2, TUF

Since the participation of the members in the Meeting takes place exclusively through the Designated Representative pursuant to art. 135-undecies of the TUF and art. 16 of the Articles of Association and, therefore, without physical participation by the members, those who have the right to vote may individually submit proposals for resolutions on the items on the agenda of the Meeting - pursuant to art. 126-bis, paragraph 1, penultimate period, of the TUF and art. 135-undecies.1, paragraph 2, of the TUF - within the fifteenth day preceding the date of the single call of the Meeting (i.e. by 7 April 2026).

The aforementioned proposals, formulated in a clear and complete manner, must indicate the item on the agenda of the Meeting to which they refer and the text of the proposed resolution. The resolution proposals received by the Company within the terms and with the methods illustrated above will be published by the Company within two days following the deadline (by Thursday 9 April 2026) on the Company’s website (www.sys-datgroup.com in the section “Governance/Shareholders’ Meeting”).

For the purposes of the relevant publication, as well as in relation to the conduct of the Meeting proceedings, the Company reserves the right to verify the relevance of the proposals to the items on the agenda, their completeness, their compliance with the applicable legislation and the legitimacy of the proposers.

In the event of proposals for resolutions on the items on the agenda that are alternatives to those formulated by the Board, the Board's proposal will be put to the vote first (unless it is withdrawn) and, only if such a proposal is rejected, the proposals of the members will be put to the vote. Such proposals, even in the absence of a proposal from the Board, will be submitted to the Meeting starting from the proposal presented by the members representing the largest percentage of the capital. Only if the proposal put to the vote is rejected, the next proposal in order of capital represented will be put to the vote.
