EKTER S.A. APPLIED FOR THE 7^th GRADE CONSTRUCTION LICENSE

Athens, October 9, 2025

EKTER S.A. announces that, having now met all the necessary criteria, it has applied to the Ministry of Infrastructure and Transport for obtaining the highest-level 7^th grade
construction license.

Obtaining the 7^th grade construction license upgrades EKTER S.A.'s prospects and signals its entry into a new phase of growth, as the Company will be eligible to participate in
even larger public and private projects, without the limitation of the financial adequacy and technical capacity criteria of the 7^th grade, thus gaining access to a broader pool of
tenders.
