If a Fiduciary Depositary Receipts (“FDR”) holder wishes to attend the meeting he has to be recorded as a shareholder in the share register of the Company prior to the Registration Date. Anyone not being a shareholder on the Registration Date may not attend or vote at the AGM.

Withdrawal of FDRs and Conversion into A-shares

An FDR holder who wants to convert FDRs into A-shares has to request this conversion in accordance with conditions 12 and 16 of the Terms and Conditions of the Amended and Restated Fiduciary Deposit Agreement dated 26 September 2001. This document is available at the Banque et Caisse d’Épargne de l’État, Luxembourg. No charge for conversion will be requested for natural persons who are not yet shareholders of category A and who proceed to a conversion of a maximum of 10,000 FDRs into A-shares, allowing them to participate in the AGM of 2 April 2026.

The latest date for withdrawing FDRs and converting into A-shares for attendance at the AGM is 19 March 2026 at 4:30 p.m. CET. Shareholders who have converted their FDRs into A-shares prior to that date will receive a copy of the AGM documents and details required to attend this year’s AGM. Please feel free to contact Banque et Caisse d’Épargne de l’État, Luxembourg, for further queries in this respect, at the following address: securitisation.irm@spuerkeess.lu

Voting instructions

The FDR holder is entitled, subject to any applicable provisions (e.g. Luxembourg law, articles of association, shareholders’ thresholds and concession agreement) to instruct the Fiduciary via his bank as to the exercise of the voting rights by means of a voting certificate available on request at the bank where the FDRs are held.

In order for the voting instructions to be valid, the voting certificate form must be completed and duly signed by the FDR holder or, as the case may be, the beneficial owner. Please feel free to contact Banque et Caisse d’Épargne de l’État, Luxembourg, for further queries in this respect at the following address: securitisation.irm@spuerkeess.lu

Upon receipt of the voting certificate on or before the date determined by the Fiduciary (being at the latest 1 April 2026 at 10:30 a.m. CET) with such certification and evidence as requested by the Fiduciary or by the Company, the Fiduciary shall transmit to the Company the relevant certifications and supporting evidence and the Company shall verify whether the relevant holders of FDRs or the beneficial owners thereof would qualify as an A-shareholder of the Company if in lieu of FDRs they would hold the corresponding number of A-shares.

If within eight Luxembourg business days from the receipt of such certification and supporting evidence, the Company has not notified the Fiduciary of its rejection of the request of a holder to exercise its voting rights pertaining to the A-shares underlying its FDRs, the Company shall be deemed to have accepted the relevant voting request.

After receipt of the written approval of the voting request by the Company, the Fiduciary shall vote or cause to be voted in accordance with the instructions set forth in such requests. The Fiduciary may designate and appoint authorized representatives to attend the meeting and vote on behalf of the FDR holders.

The voting instructions are deemed to be irrevocable and definitive 48 hours prior to the time for which the meeting has been convened, i.e. at the latest on 31 March 2026 at 10:30 a.m. CET. If the Fiduciary has not received voting instructions from the FDR holder, the Fiduciary shall be deemed to have been instructed to vote in the manner proposed by the Board of Directors in the relevant meeting.

There will be no vote under item 20. Miscellaneous
