Pursuant to Articles 13 and 14 of the Articles of Association, the Company has decided to exercise the option provided therein, stipulating that participation in the Shareholders' Meeting by those entitled to vote may take place exclusively by granting a proxy to the representative designated by the Company pursuant to Article 135-undecies of Legislative Decree No. 58 of February 24, 1998 ("TUF") - Monte Titoli S.p.A., with registered office in Milan, ("Designated Representative" or "Monte Titoli") - and via telecommunication means, in the manner specified below, thereby precluding the physical attendance of individual shareholders. Proxies or sub-proxies may also be granted to the Designated Representative pursuant to Article 135-novies of the TUF, notwithstanding Article 135-undecies, paragraph 4, of the TUF, in accordance with the procedures specified below.

The subscribed and paid-in share capital amounts to €616,605.80 and is represented by 54,076,580 ordinary shares with no par value. Each ordinary share entitles the holder to one vote. As of today, the Company does not hold any treasury shares.

Pursuant to Article 13 of the Bylaws and Article 83-sexies of the TUF, the right to attend the Shareholders' Meeting and exercise voting rights-exclusively through the Designated Representative-is evidenced by a notification to the Company, issued by the intermediary in accordance with its accounting records, in favor of the person entitled to vote, based on records as of the close of business on the seventh trading day preceding the date set for the Shareholders' Meeting (record date - April 20, 2026); credit and debit entries made to accounts after that date are not relevant for the purpose of establishing eligibility to exercise voting rights at the Shareholders' Meeting.

The notice must be received by the Company by the end of the third trading day preceding the date of the Shareholders' Meeting, i.e., by April 24, 2026. The right to attend and vote remains valid if the notice is received by the Company after the aforementioned deadline, provided it is received before the start of the proceedings of the specific meeting. The notice to the Company is provided by the intermediary at the request of the person entitled to vote.

The Directors, the Statutory Auditors, the Designated Representative, the secretary of the meeting, and the representatives of the independent audit firm, as well as other persons entitled by law, other than those entitled to vote, may participate in the Shareholders' Meeting via telecommunication means that also ensure their identification . Instructions for participating in the Shareholders' Meeting via telecommunication means will be provided by the Company to interested parties, in compliance with the applicable regulatory provisions for such cases.

A proxy may be granted, at no cost to the principal (except for any shipping costs), with voting instructions on all or some of the items on the agenda.

The proxy must be granted using the specific proxy form available, along with the relevant instructions for

completion and submission, at the Company's registered office and on the Company's website.

The proxy form with voting instructions must be received, together with a copy of a valid identification document of the Principal or, if the Principal is a legal entity, of the current legal representative or another person with appropriate authority, along with documentation certifying such status and authority, by the aforementioned Designated Representative, by the end of the second trading day preceding the date of the Shareholders' Meeting (i.e., by 11:59 p.m. on April 27, 2026, if on first call, or by April 28, 2026, if on second call), using the following alternative methods: (i) transmission of a digitally reproduced copy (PDF) to the certified email address rd@pec.euronext.com (subject line "Proxy for ENERGY 2026 Shareholders' Meeting") from their certified email account (or, failing that, from their regular email account; in such case, the proxy with voting instructions must be signed with a qualified or digital electronic signature); (ii) sending the original, via courier or certified mail with return receipt, to the attention of the Register Services department, at Monte Titoli S.p.A., Piazza degli Affari No. 6, 20123 Milan (Ref.

As permitted by the Decree, notwithstanding Article 135-undecies, paragraph 4 of the TUF, those who do not intend to avail themselves of the participation method provided for in Article 135-undecies of the TUF may, alternatively, participate by granting a proxy or sub-proxy to the same Designated Representative pursuant to Article 135-novies of the TUF, containing voting instructions on all or some of the items on the agenda, by using the proxy/sub-proxy form available on the Company's website.

To submit proxies or sub-proxies, the procedures outlined in the proxy form must be followed.
