ATHENS, GREECE, October 13, 2025: Okeanis Eco Tankers Corp. ("OET" or the
"Company") (NYSE:ECO / OSE:OET) today announced that each of Robert Knapp and
Joshua Nemser have decided to resign as directors of the Company, effective
October 10, 2025. The two resignations did not result from any disagreement with
the Company or its management.

The board of directors of the Company has not yet determined whether to reduce
the size of the board or to fill the relevant vacancies.

The board of directors remains comprised of a majority of independent directors.
The composition of each of the committees of the board of directors remains the
same and is unaffected by these resignations, except for the remuneration
committee, which remains comprised of Charlotte Stratos and Francis "Frank"
Dunne.
 
Ioannis Alafouzos, Chairman of the board, stated:
"We sincerely thank Robert and Joshua for their many contributions and
dedication to Okeanis. They both served as directors since the beginning of our
journey, over seven years ago. Their experience, expertise, and guidance, were
instrumental in forming the path that the Company has taken. We regret that they
have resigned and wish them well."
