Presentation of 2023 Financial Results

to the Representatives of the Capital Market

The presentation of the annual financial results of EYDAP to the representatives of the capital market took place today, Thursday, April 25th, via video conference. The briefing was attended by CEO Haris Sahinis and Director of Financial Analysis and Investor Relations, Ilias Dedousis.

The financial results of the year were presented in detail as well as the reasons that played a key role in their formation, such as the reduction in operating costs, mainly due to the reduction in the cost of electricity, and the parallel increase in turnover. The Company's turnover amounted to €351.6 million from €343.5 million in 2022, showing an increase of 2.4% (+€8.1 million) while operating costs decreased by - 1.8% or -€6 million and amounted to €329.8 million from €335.8 million in 2022. The dividend proposed at the General Meeting amounts to €0.10 gross.

Particular emphasis was placed on the Company's ten-year development and investment plan of 2.1 billion euros, which ensures the viability of the Company and the uninterrupted provision of water and sewerage services.

The new law of the Ministry of Energy and Environment, which is to be voted within the next few days, gives particular flexibility to the Company, among other things, for carrying out operation and maintenance activities of networks and water supply and wastewater facilities outside Attica, flexibilities for the development of RES and the reuse of recycled water, the possibility of obtaining control of businesses in related industries, etc.

With regard to the new regulatory framework, the Company is awaiting the issuance of the new Joint Ministerial Decision on water pricing rules. After the issuance of the JMD, the Company will propose to the Ministry of Environment and Energy, since RAEWW is not yet fully operational, the new tariff based on the methodology of the permitted income.

The results of the consumer satisfaction survey carried out by EYDAP were also presented, which reflected the positive image that exists for the Company (75% satisfaction), the preference for EYDAP compared to other utilities and the shift of customers to electronic services. Finally, the Company's action plan against climate change and the possibility of water shortages, was analyzed.

We inform the investment community that the Company's presentation is posted on the EYDAP website (www.eydap.gr) in the Investor Relations section.
