Okeanis Eco Tankers Corp. – New Financings Update
ATHENS, GREECE, May 4, 2026 – Okeanis
Eco Tankers Corp. (the “Company” or “OET”) (NYSE:ECO / OSE:OET), announced today that it has entered into three
new loan facility agreements.
We entered into a $90.0 million facility agreement
to finance a portion of the acquisition price of our two recently acquired newbuilding contracts relating to two new Suezmax vessels,
each under construction at Daehan Shipbuilding Co., Ltd., to be named Nissos Tigani and Nissos Vous, with expected
deliveries from the shipyard in May 2026 and July 2026, respectively (the “Nissos Tigani and Nissos Vous Facility”).
The Nissos Tigani and Nissos Vous Facility is provided by a syndicate of banks, led and arranged by E.SUN Commercial Bank, Ltd. It
contains an interest rate of Term SOFR plus 120 basis points, matures in eight years, and will be repaid in quarterly installments of
$1.07 million, together with aggregate balloon installments of $55.76 million at maturity, related to both vessels. It will be secured
by, among other things, mortgages over the Nissos Tigani and the Nissos Vous, and it will be guaranteed by the Company.
The transaction is expected to close in May 2026 and July 2026, respectively, for each of the two vessels.
We entered into a $50.0 million facility agreement
to finance the previously announced declaration of our option to purchase back the Nissos Rhenia from its current sale and leaseback
financier (the “Nissos Rhenia Facility”). The Nissos Rhenia Facility is provided by a prominent Greek bank. It contains an
interest rate of Term SOFR plus 125 basis points, matures in seven years, and will be repaid in quarterly installments of $0.825 million,
together with a balloon installment of $26.9 million at maturity. It will be secured by, among other things, a mortgage over the Nissos
Rhenia, and it will be guaranteed by the Company. The transaction is expected to close in May 2026.
We entered into a $50.0 million facility agreement
to finance the previously announced declaration of our option to purchase back the Nissos Despotiko from its current sale and leaseback
financier (the “Nissos Despotiko Facility”). The Nissos Despotiko Facility is provided by another prominent Greek bank. It
contains an interest rate of Term SOFR plus 130 basis points, matures in nine years, and will be repaid in quarterly installments of $0.825
million, together with a balloon installment of $20.3 million at maturity. It will be secured by, among other things, a mortgage over
the Nissos Despotiko, and it will be guaranteed by the Company. The transaction is expected to close in June 2026.
All facility agreements contain standard representations,
warranties and covenants, including financial covenants, and are subject to standard conditions precedent, such as the delivery of the
relevant vessel.
Iraklis Sbarounis, CFO of the Company, commented:
“We are pleased to announce our most
recent bank financing transactions.
First, these transactions complete the funding
of the acquisition of our two resale newbuilding Suezmaxes, following our successful equity raise in January. Similar to the structure
we executed for the Nissos Piperi and Nissos Serifopoula, we structured the acquisitions of the Nissos Tigani and Nissos Vous in a way
that we believe preserves our dividend capacity, funded by fresh accretive equity capital and competitive bank debt. This transaction
has been our third with Taiwanese banks in the last two years. We are pleased with the progress and relationships we are developing in
that market, and look forward to working with current and new partners in the future.
Second, these transactions also complete our
transition away from all our legacy sale and leaseback transactions. The sale and leaseback transactions served their purpose well in
supporting the start of our journey as a public entity; we are now very pleased to replace them with competitive bank debt, which we believe
to be a reflection of how Okeanis as a platform has matured through the years, how the market views our performance and capital structure,
and the confidence we enjoy by our financiers. The two vessels are each financed by separate Greek banks. We continue fostering the relationships
established by the Alafouzos family in the Greek banking market, a market that we expect may always play a significant role in our capital
structure, which knows the shipping market, and is built with long-term trust in mind.
Over the last few years we have refinanced
and improved our debt structure. Since the pre LIBOR to SOFR transition era in early 2023, and once these new transactions close, we estimate
that our debt margin pricing will have improved by over 200 basis points on average across our fleet, resulting in significant interest
expense savings. We have extended loan maturities, such that some loans run until 2035, and we have improved our daily debt service breakeven
costs. We are confident that we are well positioned to continue capitalizing on the market, having set up our platform with a competitive
capital structure and with a focus on shareholder returns.”
