(a) a shareholder controlling the Company, or another legal person or entity controlled by that shareholder, 

(b) a member of the Board of Directors or of the management of the Company in general or shareholder who exercises control over the Company, or another legal person or entity controlled by a shareholder who exercises control over the Company, 

(c ) an employee or a Certified Auditor of the Company or of shareholder who exercises control over the Company, or other legal person or entity controlled by a shareholder who controls the Company, 

(d) a spouse/wife or a first degree relative of one of the natural persons mentioned in the above cases (a) to (c). 

The appointment and revocation or replacement of the shareholder’s proxy or representative shall be made in writing or by electronic means and shall be submitted to the Company at least forty eight (48) hours before the date set for the Annual Ordinary General Meeting (namely no later than 16.06.2025 at 15:30 the latest), or in the case of shareholders  identified through intermediaries, by means of confirmations or notices pursuant to Articles 5 and 6 of Regulation (EU) 2018/1212 provided by the intermediaries.
