Okeanis Eco Tankers Corp. – Key Information relating to Q2
2026 dividend
ATHENS, GREECE, August 4, 2026 - Okeanis Eco Tankers
Corp. (“OET” or the “Company”) (NYSE: ECO / OSE: OET), announced today that the Company's board of directors (the
“Board”) has declared a dividend on its common shares (the “Dividend”).
Due to implementation of the Central Securities
Depository Regulation (“CSDR”) in Norway, shareholders who hold common shares registered in Euronext Securities Oslo (“VPS”),
Norway’s central securities depository, should please note the information on the payment date to the common shares registered in
VPS below.
The New York Stock Exchange (“NYSE”) settles its trades
on a T+1 basis, while the Oslo Stock Exchange (“OSE”) settles its trades on a T+2 basis. As a result, there will be different
ex-dividend dates between the two exchanges, as set out below.
Key information relating to the Dividend:
| · | Dividend amount: USD 5.25 per common share. |
| · | Declared currency: USD. Dividends payable to common shares registered in the Euronext VPS will be distributed in NOK. |
| · | Date of Board approval: August 4, 2026. |
| · | Last day including right OSE: August 12, 2026, the last date on which the Company’s common shares trading on the OSE will include
the entitlement to the Dividend. |
| · | Last day including right NYSE: August 13, 2026, the last date on which the Company’s common shares trading on the NYSE will
include the entitlement to the Dividend. |
| · | Ex-date OSE: August 13, 2026, the date on which the Company’s common shares will begin trading on the OSE without the entitlement
to the Dividend. |
| · | Ex-date NYSE: August 14, 2026, the date on which the Company’s common shares will begin trading on the NYSE without the entitlement
to the Dividend. |
| · | Record date OSE and NYSE: August 14, 2026 |
| · | Payment date: August 21, 2026. Due to the implementation of CSDR in Norway, the Dividend payable on common shares that are registered
in the Euronext VPS is expected to be distributed to Euronext VPS shareholders on or about August 26, 2026. |
The Company encourages you to contact your bank, broker, nominee or
other institution if you have any questions regarding the mechanics and timing of having the Dividend attributable to your common shares

Forward Looking Statements
This communication contains “forward-looking statements”,
including as defined under U.S. federal securities laws. Forward-looking statements provide the Company’s current expectations or
forecasts of future events. Forward-looking statements include statements about the Company’s expectations, beliefs, plans, objectives,
intentions, assumptions and other statements that are not historical facts or that are not present facts or conditions. Words or phrases
such as “anticipate,” “believe,” “continue,” “estimate,” “expect,” “hope,”
“intend,” “may,” “ongoing,” “plan,” “potential,” “predict,” “project,”
“should,” “will” or similar words or phrases, or the negatives of those words or phrases, may identify forward-looking
statements, but the absence of these words does not necessarily mean that a statement is not forward-looking. Forward-looking statements
are subject to known and unknown risks and uncertainties and are based on potentially inaccurate assumptions that could cause actual results
to differ materially from those expected or implied by the forward-looking statements. The Company’s actual results could differ
materially from those anticipated in forward-looking statements for many reasons, including as described in the Company’s filings
with the U.S. Securities and Exchange Commission (the “SEC”). Accordingly, you should not unduly rely on these forward-looking
statements, which speak only as of the date of this communication. Factors that could cause actual results to differ materially include,
but are not limited to, the Company’s operating or financial results; the Company’s liquidity, including its ability to service
its indebtedness; competitive factors in the market in which the Company operates; shipping industry trends, including charter rates,
vessel values and factors affecting vessel supply and demand; future, pending or recent acquisitions and dispositions, business strategy,
areas of possible expansion or contraction, and expected capital spending or operating expenses; risks associated with operations; broader
market impacts arising from war (or threatened war) or international hostilities; risks associated with pandemics, including effects on
demand for oil and other products transported by tankers and the transportation thereof; and other factors listed from time to time in
the Company’s filings with the SEC. Except to the extent required by law, the Company expressly disclaims any obligations or undertaking
to release publicly any updates or revisions to any forward-looking statements contained herein to reflect any change in the Company’s
expectations with respect thereto or any change in events, conditions, or circumstances on which any statement is based. You should, however,
review the factors and risks the Company describes in the reports it files and furnishes from time to time with the SEC, which can be
obtained free of charge on the SEC’s website at www.sec.gov.
