NOT FOR RELEASE, PUBLICATION OR DISTRIBUTION, IN WHOLE OR IN PART, DIRECTLY OR
INDIRECTLY, IN OR INTO THE UNITED STATES, AUSTRALIA, CANADA OR JAPAN, OR ANY
OTHER JURISDICTION IN WHICH THE RELEASE, PUBLICATION OR DISTRIBUTION WOULD BE
UNLAWFUL. THIS ANNOUNCEMENT DOES NOT CONSTITUTE AN OFFER OF ANY OF THE
SECURITIES DESCRIBED HEREIN.

ATHENS, GREECE, 20 January 2026 – Okeanis Eco Tankers Corp. (together with its
subsidiaries, unless context otherwise dictates, “OET” or the “Company”) (NYSE:
ECO, OSE: OET) today announces a contemplated acquisition of two Suezmax tanker
newbuilding resales (the “Vessel Acquisitions”), and a contemplated offering of
new common shares (the “Offering”).

The completion of the Vessel Acquisitions are subject to completion of the
Offering, as further described below.

The Vessel Acquisitions
The Company has entered into two memoranda of agreement, whereby the Company,
pursuant to each individual memorandum of agreement, has agreed to purchase one
newbuilding Suezmax vessel (with an estimated approximate deadweight tonnage of
157,000), currently under construction at Daehan Shipbuilding Co., Ltd., a South
Korean shipyard, being sister vessels to two vessels acquired during January
2026, each from an unrelated third-party seller for an acquisition price of USD
99.3 million per vessel. Each vessel is expected to be delivered from the
shipyard in the second quarter of 2026.
Each of the Vessel Acquisitions is contingent on, among other things, the
Company raising sufficient capital to fund a portion of the purchase price
through the Offering, as well as the Company obtaining the necessary debt
financing required to fully fund the Vessel Acquisitions beyond equity raised in
the Offering, but the purchase of one vessel is not contingent on the purchase
of the other.

The Offering
In connection with the Vessel Acquisitions, the Company is contemplating an
offering of new common shares (the “Offer Shares”) to raise gross proceeds of
approximately USD 115 million.
The subscription price for the Offer Shares and the total number of Offer Shares
will be determined by the Board of Directors of the Company (the "Board") based
on an accelerated bookbuilding process.
The net proceeds from the Offering are expected to be used to partly finance the
consideration to the sellers in the Vessel Acquisitions. However, if one or both
of the Vessel Acquisitions does not consummate, the net proceeds from the
Offering may be used for general corporate purposes.
The bookbuilding period for the Offering will commence today, 20 January 2026 at
22:15 CET and is expected to close on 21 January 2026 at 11:00 CET. The Company
reserves the right to at any time and in its sole discretion resolve to close or
to extend the application period or to cancel the Offering in part or in whole.
To facilitate an efficient bookbuilding process, a trading halt will be imposed
on the Company’s shares that are trading on Euronext Oslo Børs throughout the
bookbuilding period and until final results have been announced, expected on or
about 13:00 CET on 21 January 2026.

Notification of allocation is expected to take place on or about 21 January 2026
at 13:00 CET. Payment and delivery is expected to take place on 23 January 2026
based on delivery vs payment (DVP, T+2). The Offer Shares will be delivered
through the DTC. The Offer Shares will be available for trading on New York
Stock Exchange once the Offer Shares have been issued and settlement has taken
place through the DTC, expected on 23 January 2026. After delivery of Offer
Shares, such shares may be transferred from DTC to Euronext Securities Oslo (the
"VPS") in accordance with the customary arrangements for transfers of the
Company’s shares between DTC and VPS.

The minimum application and allocation amount has been set to the USD equivalent
of EUR 100,000. The Board may however, at its sole discretion, allocate Offer
Shares for amounts below the USD equivalent of EUR 100,000 to the extent
exemptions from the prospectus requirement in accordance with applicable
regulations, including the Norwegian Securities Trading Act and ancillary
regulations, are available.

Completion of the Offering by settlement of Offer Shares in the Depository Trust
Company (DTC) to investors in the Offering is subject to, among other things,
(i) all corporate resolutions of the Company required to complete the Offering
being validly made, including without limitation, the Board or a committee
thereof approving the allocation and issuance of Offer Shares; and (ii) the
agreements for the Vessel Acquisitions remaining in full force and effect at the
time of settlement of the Offer Shares. The Offering will be cancelled if the
conditions are not fulfilled and may be cancelled by the Company in its sole
discretion for any other reason.

Completion of the Offering is not conditional upon completion of the Vessel
Acquisitions. The Company has entered into agreements with respect to the
Vessels Acquisitions and expects such Vessel Acquisitions to be completed in
accordance with those agreements subject to and following completion of the
Offering, as well as the Company obtaining the necessary debt financing required
to fully fund the vessels beyond equity raised in the Offering.

The Offering will be made pursuant to the Company’s shelf registration statement
on Form F-3 (File No. 333-287032), which was declared effective by the U.S.
Securities and Exchange Commission (the “SEC”) on 21 May 2025, and is being made
by means of a prospectus supplement prepared specifically in relation to the
Offering and to be filed under Rule 424(b) under the U.S. Securities Act of
1933, which can be obtained at www.sec.gov. A written prospectus may also be
obtained by contacting Fearnley Securities AS at prospectus@fearnleys.com,
Clarksons Securities AS at compliance.oslo@clarksons.com or Pareto Securities AS
at subscription@paretosec.com.

The Company will announce the results of the Offering, the number of Offer
Shares allocated in the Offering and the subscription price for the Offer Shares
through an announcement expected to be published on or about 12:45 CET on 21
January 2026.

The shareholders of the Company will not have preferential rights to subscribe
for new shares in the Offering. The Board has considered the Offering in light
of the rules of equal treatment set out in the Norwegian Securities Trading Act
section 5-14. The Board is of the opinion that the Offering will reduce
execution and completion risk as it, amongst other things, allow for the Company
to raise capital more quickly, and is more flexible, especially considering the
Offering being part of a larger transaction comprising the Vessel Acquisitions
and that the shares of the Company are traded on both the New York Stock
Exchange and Euronext Oslo Børs. Furthermore, the Board is of the opinion that,
in the current market, the Offering enables the Company to raise equity at a
lower discount compared to a rights issue. It has also been taken into
consideration that the Offering is based on a publicly announced accelerated
bookbuilding process and that the Company has applied for a trading halt on
Euronext Oslo Børs (as described above) to facilitate participation of investors
trading on the Euronext Oslo Børs. On this basis, the Board has concluded that
the Offering is in the interest of the Company and its shareholders and is in
compliance with the requirements relating to equal treatment as set out in the
Norwegian Securities Trading Act section 5-14.

This communication contains “forward-looking statements”, including as defined
under applicable laws, such as the US Private Securities Litigation Reform Act
of 1995. Forward-looking statements provide the Company’s current expectations
or forecasts of future events. Forward-looking statements include statements

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 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.
