Advance A and Advance B will be repaid in quarterly instalments of approximately $0.9 million and $1 million, respectively, together with a balloon instalment of approximately $40.8 million and $36.0 million, respectively, payable at maturity. Advance A was drawn on May 29, 2025, and Advance B was drawn on July 31, 2025. The New Nikouria and Anafi Facility is secured by, among other things, security over the *Nissos Nikouria* and *Nissos Anafi*, and is guaranteed by the Company.

● On June 17, 2025, we entered into a new $65.0 million senior secured credit facility to finance the option to purchase back the VLCC vessel *Nissos Kea* (the "Nissos Kea New Facility").

● In connection with the refinancing of the facilities of *Nissos Nikouria* through the New Nikouria and Anafi Facility and *Nissos Kea* through the Nissos Kea New Facility, the Company recognized a non-cash loss of $1.1 million, referred to as "loss on debt extinguishment", relating to the write-off of the unamortized portion of a previously recorded modification gain.

***USE AND RECONCILIATION OF ALTERNATIVE PERFORMANCE MEASURES***

The Company together with its wholly owned subsidiaries, (the "Group") evaluates its vessels' operations and financial results principally by assessing their revenue generation (and not by the type of vessel, employment, customer, or type of charter). Among others, TCE, Daily TCE rate, EBITDA, Adjusted EBITDA, Daily Opex, Adjusted Profit/(loss) and Adjusted Earnings/(loss) per share are used as key performance indicators.

**Daily TCE rate**

In the shipping industry, economic decisions are based on vessels' deployment upon anticipated TCE rates and time charter equivalent revenue, and industry analysts typically measure shipping freight rates in terms of TCE rates. This is because under time-charter and bareboat contracts the customer usually pays the voyage expenses, while under voyage charters the ship-owner usually pays the voyage expenses, which typically are added to the hire rate at an approximate cost. In a voyage charter contract, consideration is received for the use of a vessel between designated ports for the duration of the voyage only, at an agreed upon rate per volume of cargo carried. In a time charter contract, the customer (also known as the charterer) is responsible to pay for fuel consumed and port expenses incurred during the agreed period of time. In a voyage charter contract, the Company is responsible for maintaining the voyage, including vessel scheduling and routing, as well as any related voyage expenses, such as fuel, port and other expenses. Under voyage charters, the majority of voyage expenses are generally borne by us whereas for vessels in a time charter, such expenses are borne by the time charter operator. In a bareboat charter, the customer pays for all of the vessel's operating expenses, and undertakes to maintain the vessel in a good state of repair and efficient operating condition and drydock the vessel during this period as per the classification society requirements. We may incur voyage related expenses when positioning or repositioning vessels before or after the period of a time or other charter, during periods of commercial waiting time or while off-hire during drydocking or due to other unforeseen circumstances. Because of the different nature of these types of arrangements, the amount of revenues earned by the Company can differ significantly between them.

The Daily Time Charter Equivalent Rate ("TCE rate") is a measure of the average daily revenue performance of a vessel. The TCE rate and time charter equivalent revenue (TCE) are not measures of revenue under generally accepted accounting principles (i.e., they are non-GAAP measures) or IFRS and should not be considered as an alternative to any measure of revenue and financial performance presented in accordance with IFRS. We calculate the TCE rate by dividing revenues (time charter and/or voyage charter revenues), less commission and voyage expenses (which then equals "time charter equivalent revenue"), by the number of operating days (we define operating days as calendar days less any scheduled or unscheduled days that our vessels are off-hire due to unforeseen technical and commercial circumstances) during that period. Our calculation of the TCE rate and time charter equivalent revenue may not be comparable to that reported by other companies. We define calendar days as the total number of days the vessels were in our possession for the relevant period. Calendar days are an indicator of the size of our fleet during the relevant period and affect the amount of expenses that we record during that period. We and other companies in the shipping industry use operating days to measure the aggregate number of days in a period that our vessels generate revenues. The period a vessel is not being chartered or is unable to perform the services for which it is required under a charter is "off-hire".

We use the TCE rate and time charter equivalent revenue because they provide a means of comparison between different types of vessel employment and, therefore, assists our decision-making process with regards to the operation and use of our vessels and in evaluating our financial performance. We believe the TCE rate and time charter equivalent revenue provide additional meaningful information to our investors, constituting a comparison to Revenue, the most directly comparable GAAP and IFRS measure, that also enables our management to evaluate the performance and deployment of our fleet and in evaluating their financial performance. The TCE rate and time charter equivalent revenue are measures used to compare period-to-period changes in a company's performance, and management believes that the TCE rate and time charter equivalent revenue provide meaningful information to our investors.

------

The following table sets forth our computation of TCE rates, including a reconciliation of revenues to the TCE rates (unaudited) for the periods presented:

**Daily Opex**

Daily Opex per vessel is an alternative performance measure that provides meaningful information to our management with regards to our vessels' efficiency and deployment. Daily Opex is not a measure under generally accepted accounting principles (i.e., it is a non-GAAP measure) or IFRS and should not be considered as an alternative to any measure of expenses and financial performance presented in accordance with IFRS. Our reconciliation of daily Opex, including management fees, may deviate from that reported by other companies. We believe Daily Opex provides additional meaningful information in conjunction with Vessel operating expenses, the most directly comparable GAAP and IFRS measure, because it provides meaningful information to our investors in evaluating our financial performance. Also, it is an alternative measure that provides meaningful information to our management with regards to our vessels' efficiency and deployment.

Daily Opex is calculated as vessel operating expenses and technical management fees divided by calendar days, for the relevant periods.

The following table sets forth our reconciliation of daily Opex (unaudited) for the periods presented:

**EBITDA, Adjusted EBITDA, Adjusted Profit and Adjusted Earnings per share**

Earnings before interest, tax, depreciation and amortization (EBITDA) is an alternative performance measure, derived directly from the statement of profit or loss and other comprehensive income by adding back to profit/(loss) depreciation, amortization, interest and finance costs and subtracting interest income. Adjusted EBITDA is defined as EBITDA before non-recurring items, unrealized losses/(gains) on derivatives, realized losses/(gains) on derivatives, foreign exchange (gains)/losses, (gain)/loss from loan modifications and loss on debt extinguishment. Adjusted profit/(loss) is defined as reported profit/(loss) before non-recurring items, unrealized losses/(gains) on derivatives, impairment loss, loan modification gain/(loss), loss on debt extinguishment and gain/(loss) on disposal of vessels, if any. Adjusted earnings/(loss) per share is defined as adjusted profit/(loss) divided by the weighted average number of common shares outstanding in the period.

Furthermore, EBITDA, Adjusted EBITDA, Adjusted profit/(loss) and Adjusted earnings/(loss) per share have certain limitations in use and should not be considered alternatives to reported profit/(loss), operating profit, cash flows from operations, earnings per share or any other GAAP or IFRS measure of financial performance. EBITDA, Adjusted EBITDA, Adjusted profit/(loss) and Adjusted earnings/(loss) per share exclude some, but not all, items that affect profit/(loss).

------

EBITDA, Adjusted EBITDA, Adjusted Profit and Adjusted Earnings per share are not measures of profit under generally accepted accounting principles (i.e., they are non-GAAP measures) or IFRS and should not be considered as an alternative to any measure of revenue and financial performance presented in accordance with IFRS. EBITDA, Adjusted EBITDA, Adjusted Profit and Adjusted Earnings per share are used as supplemental financial measures by management and external users of financial statements to assess our operating performance. We believe that EBITDA, Adjusted EBITDA, Adjusted Profit and Adjusted Earnings per share assist our management and our investors by providing useful information that increases the comparability of our operating performance from period to period and against our previous performance and the operating performance of other companies in our industry that provide relevant information. We believe EBITDA, Adjusted EBITDA, Adjusted Profit and Adjusted Earnings provide additional meaningful information in conjunction with profit, the most directly comparable GAAP and IFRS measure, because they provide meaningful information in evaluating our financial performance.

Our method of computing EBITDA, Adjusted EBITDA, Adjusted profit/(loss) and Adjusted earnings/(loss) per share may not be consistent with similarly titled measures of other companies and, therefore, might not be comparable with other companies.

#### Exhibit 99.2

#### CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS
The discussion set out below contains forward-looking statements, including as defined under U.S. federal securities laws, which reflect our current views or expectations with respect to future events and financial performance. Forward-looking statements include statements concerning plans, beliefs, objectives, intentions, goals, strategies, future events or performance, and underlying assumptions and other statements, which are statements other than statements of historical facts or that are not present facts or conditions. When used herein, statements that are predictive in nature, that depend upon or refer to future events or conditions, or that include words such as "anticipate," "believe," "expect," "intend," "estimate," "forecast," "project," "plan," "potential," "continue," "seeks," "views," "possible," "likely," "may," "should," and similar words, phrases, or expressions identify forward-looking statements, and the negatives of those words, phrases, or expressions, or statements that events, conditions, or results "can," "will," "may," "must," "would," "could," or "should" occur or be achieved and similar expressions in connection with any discussion, expectation, or projection of future operating or financial performance, costs, regulations, events, or trends identify forward-looking statements. 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.

The forward-looking statements contained herein are based upon various assumptions, many of which are based, in turn, upon further assumptions, including without limitation, management's examination of historical operating trends, data contained in our records, and other data available from third parties. Although we believe that these assumptions were reasonable when made, because these assumptions are inherently subject to significant uncertainties and contingencies that are difficult or impossible to predict and are beyond our control, we cannot assure you that we will achieve or accomplish these expectations, beliefs, or projections.

In addition to these assumptions and matters discussed elsewhere herein, important factors that, in our view, could cause actual results to differ materially from those discussed in the forward-looking statements include the following:

● our ability to maintain or develop new and existing customer relationships with major crude oil companies and major commodity traders, including our ability to enter into long-term charters for our vessels, and those we may acquire in the future;

● our future operating and financial results;

● our future vessel acquisitions, sales, our business strategy, and expected and unexpected capital spending or operating expenses, including general and administrative, drydocking, crewing, bunker costs, and insurance costs;

● our financial condition and liquidity, including our ability to pay amounts that we owe and to obtain financing in the future to fund capital expenditures, acquisitions, and other general corporate activities;

● oil tanker industry trends, including fluctuations in charter rates and vessel values and factors affecting vessel supply and demand;

● our ability to take delivery of, integrate into our fleet, and employ any vessels we may acquire in the future, or any newbuildings we may acquire or order in the future and the ability of shipyards to deliver vessels on a timely basis;

● our dependence on our technical manager, Kyklades Maritime Corporation, an affiliate of our Chairman, Mr. Ioannis Alafouzos, to operate our vessels;

● the aging of our vessels, and those we may acquire in the future, and resultant increases in operation and drydocking costs;

● the ability of our vessels, and any vessels we may acquire in the future, to pass classification inspections and vetting inspections by oil majors and big chemical corporations, or other authorities;

[**Table of Contents**](#TOC)

● significant changes in vessel performance, including increased vessel breakdowns;

● length and number of off hire days, drydocking requirements, and insurance costs;

● availability of key employees and crew;

● hazards inherent in the maritime industry causing personal injury or loss of life, severe damage to or destruction of property and equipment, pollution or environmental damage, claims by third parties or customers and suspension of operations;

● repudiation, nullification, termination, modification or renegotiation of contracts;

● U.S., EU or other foreign monetary policy and foreign currency fluctuations and devaluations;

● the creditworthiness of our charterers and the ability of our contract counterparties to fulfill their obligations to us;

● our ability to repay outstanding indebtedness, to comply with the covenants contained therein, to obtain additional financing, and to obtain replacement charters for our vessels, and any vessels we may acquire in the future, in each case, at commercially acceptable rates or at all;

● changes to governmental rules and regulations or actions taken by regulatory authorities and the expected costs thereof, or changes to tax policies and other government regulations and economic conditions that are beyond our control;

● our ability to pay dividends;

#### MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following contains discussion of the results of our operations and our financial condition for the six months ended June 30, 2025 and 2024. This discussion contains forward-looking statements that involve risks, uncertainties, and assumptions. These forward-looking statements are dependent upon events, risks and uncertainties that may be outside our control which could cause actual events or conditions to differ materially from those currently anticipated and expressed or implied by such forward-looking statements. For a more complete discussion of these risks and uncertainties, please read the sections entitled "Cautionary Statement Regarding Forward-Looking Statements" herein and "Item 3. Risk Factors" in our 2024 Annual Report.

Unless the context indicates otherwise, references to the "Company", "we" or "our" include Okeanis Eco Tankers Corp. and its subsidiaries.

#### Principal Factors Affecting Our Business
The principal factors that affect our financial position, operating results and cash flows include the following:

● number of vessels owned and operated;

● voyage charter rates;

● time charter trip rates;

● period time charter rates;

● the nature and duration of our voyage charters;

● vessels repositioning;

● vessel operating expenses and direct voyage costs;

● maintenance and upgrade work;

● the age, condition and specifications of our vessels and other vessels we may acquire;

● issuance of our common shares and other securities;

● amount of debt obligations; and

● financing costs related to debt obligations.

We are also affected by the types of charters we enter into. Vessels operating on period time charters and bareboat time charters provide more predictable cash flows, but can yield lower profit margins than vessels operating in the spot charter market, either on trip time charters or voyage charters, during periods characterized by favorable market conditions.

[**Table of Contents**](#TOC)

Vessels operating in the spot charter market generate revenues that are less predictable, but can yield increased profit margins during periods of improvements in tankers rates. Spot charters also expose vessel owners to the risk of declining tanker rates and rising fuel costs in case of voyage charters.

#### Material Accounting Policies and Critical Accounting Estimates
For a description of our critical accounting judgements and key sources of estimation uncertainty, see Note 5, "Critical Accounting Judgments and Key Sources of Estimation Uncertainty" to our audited 2024 financial statements included in our 2024 Annual Report. For a description of all of our material accounting policies, see Note 4 to our audited 2024 financial statements and the section entitled "Item 5. Operating and Financial Review and Prospects" in our 2024 Annual Report. There have been no material changes from the "Critical accounting judgments and key sources of estimation uncertainty" previously disclosed in our 2024 Annual Report.

#### Important Financial and Operational Terms and Concepts
We use a variety of financial and operational terms and concepts when analyzing our performance. These include the following:

#### Revenues
Revenues primarily include revenues from time charters and voyage charters. Revenues are affected by hire rates and the number of operating days. Revenues are also affected by the mix of business between vessels on time charter and vessels operating on voyage charter. Revenues from vessels on voyage charter are more volatile, as they are typically tied to prevailing market rates.

#### Voyage and Time Charters
Voyage charters or spot voyages are charters under which the customer pays a transportation charge for the movement of a specific cargo between two or more specified ports. We pay all of the voyage expenses. Under time charters, we lease the vessel for a set length of time to a charterer, where the latter is free to sail to any port or transport any cargo of his preference (subject to legal restrictions). All voyage expenses are incurred by the charterer.

#### Commissions
We pay commissions of typically up to 3.75% of the total daily charter hire rate of each charter to unaffiliated ship brokers associated with the charter, depending on the number of brokers involved with arranging the charter.

#### Voyage Expenses
Voyage expenses mainly relate to voyage charter agreements and consist of port, canal and bunker costs that are unique to a particular voyage and are recognized as incurred. Under our time charter arrangements, voyage expenses are borne by the charterers, including bunker fuel, port charges and canal tolls.

#### Vessel Operating Expenses
Vessel operating expenses comprise all expenses relating to the operation of the vessel, including crewing, insurance, repairs and maintenance, stores, lubricants, spares and consumables and miscellaneous expenses. Vessel operating expenses can fluctuate due to factors beyond our control, such as unplanned repairs and maintenance attributable to damages or regulatory compliance and factors which may affect the shipping industry in general, such as developments relating to insurance premiums, or developments relating to the availability of crew.

#### Drydocking Costs
Drydocking costs relate to regularly scheduled intermediate survey or special survey drydocking necessary to preserve the quality of our vessels as well as to comply with international shipping standards and environmental laws and regulations. Drydocking costs can vary according to the age of the vessel, the location where the drydock takes place, shipyard availability, local availability of manpower and material, and the billing currency of the yard. Please see the section entitled "Item 18. Financial Statements — Note 4 — Summary of Material Accounting Policies" in our 2024 Annual Report. In the case of tankers, drydocking costs may also be affected by new rules and regulations.

[**Table of Contents**](#TOC)

#### Vessel Depreciation
We depreciate all our vessels on a straight-line basis over their estimated useful lives, which we estimate to be 25 years from the date of their initial delivery from the shipyard, after considering their estimated residual value. Each vessel's residual value is equal to the product of its lightweight tonnage and its estimated scrap rate. The scrap price is estimated to be approximately $400 per ton of lightweight steel. The Company may revise the estimated residual values of the vessel in the future in response to changing market conditions.

#### General and Administrative Expenses
General and administrative expenses mainly consist of employee costs, directors' liability insurance, directors' fees and expenses, executive compensation, professional fees and other expenses.

#### Management Fees
Management fees concern services provided from the technical manager of our vessels, for a wide range of shipping services, among others, technical support, maintenance, acquisitions of emissions allowances and insurance consulting, for a daily fee of $900 per vessel.

#### Inflation
Inflation has had an impact on our vessel operating expenses and corporate overheads. It is anticipated that insurance costs, which have risen over the last three years, may well continue to rise over the next few years. Oil transportation is a specialized area and the number of vessels is increasing. There is therefore expected to be an increased demand for qualified crew and this has and will continue to put inflationary pressure on crew costs. However, in a shipping downturn, costs subject to inflation can usually be controlled because shipping companies typically monitor costs to preserve liquidity and encourage suppliers and service providers to lower rates and prices in the event of a downturn. Interest on our SOFR-based loans (or loans based on another reference rate or its successor) can increase following any interest rate hikes undertaken by financial authorities (such as central banks) in response to, among other things, inflation.

#### Interest and Other Finance Costs
We incur interest expense on outstanding indebtedness under our loans, which we include in interest and other finance costs. We also incur finance costs in establishing our debt facilities. Finance costs incurred for obtaining new debt facilities are deferred and amortized to interest expense over the respective term of the debt facility using the effective interest rate method. Any unamortized balance of costs relating to debt facilities repaid or refinanced is either expensed in the period the repayment or refinancing is made, or deferred and amortized over the terms of the respective debt facility, subject to the accounting guidance regarding Debt—Modifications and Extinguishments. The unamortized finance costs are reflected as a reduction of Long-term borrowings, net of current portion, and Current portion of long-term borrowings in the consolidated statements of financial position.

#### Unrealized/Realized Gain/Loss, net from Derivatives
Unrealized/realized gain/loss from derivatives represents (1) the fluctuations in the fair value of the Company's derivative instruments, recorded as unrealized gain or loss and (2) the actual amounts paid or received upon settlement of the derivative instruments, recorded as realized gain or loss in the statements of profit or loss.

#### Important Measures and Definitions for Analyzing Results of Operations
We use a variety of financial and operational terms and concepts. These include the following:

*Calendar days*. We define calendar days as the total number of days the vessels were in our possession for the relevant period. Calendar days are an indicator of the size of our fleet during the relevant period and affect the amount of expenses that we record during that period.

*Operating days.* We define operating days as the number of calendar days in a period less any scheduled or unscheduled days that our vessels are off-hire due to unforeseen technical and commercial circumstances. We and the shipping industry uses operating days to measure the aggregate number of days in a period that our vessels actually generate revenues.

[**Table of Contents**](#TOC)

*Off-hire.* The period a vessel is not being chartered or is unable to perform the services for which it is required under a charter.

*Fleet utilization.* We calculate fleet utilization by dividing the number of operating days during a period by the number of calendar days during that period. We and the shipping industry use fleet utilization to measure a company's efficiency in finding suitable employment for its vessels and minimizing the number of days that its vessels are off-hire for reasons other than scheduled repairs or scheduled guarantee inspections in the case of new buildings, vessel upgrades, special or intermediate surveys and vessel positioning.

*Daily Time Charter Equivalent ("TCE") Rate*. The Daily Time Charter Equivalent Rate ("Daily TCE Rate") is a measure of the average daily revenue performance of a vessel. The Daily TCE Rate and time charter equivalent revenue are each not a measure of revenue under GAAP (i.e., each is a non-GAAP measure) or IFRS and should not be considered as an alternative to any measure of revenue and financial performance presented in accordance with IFRS. We calculate Daily TCE Rate by dividing revenues (time charter and/or voyage charter revenues), less commission and voyage expenses (which then equals "TCE revenue"), by the number of operating days during that period. Our calculation of the Daily TCE Rates and TCE revenue may not be comparable to that reported by other companies.

*Daily vessel operating expenses, including technical management fees*. Daily vessel operating expenses ("Daily Opex") is not a measure under generally accepted accounting principles (i.e., it is a non-GAAP measure) or IFRS and should not be considered as an alternative to any measure of expenses and financial performance presented in accordance with IFRS.Daily Opex, including technical management fees, calculated as the sum of vessel operating expenses and technical management fees divided by the calendar days of the period, is an alternative performance measure that provides meaningful information to our management with regards to our vessels' efficiency and deployment. We believe Daily Opex provides additional meaningful information in conjunction with Vessel operating expenses, the most directly comparable GAAP and IFRS measure, because it provides meaningful information to our investors in evaluating our financial performance. Our calculation of Daily Opex, including technical management fees, may differ from that reported by other companies.

#### Main components of managing our business and main drivers of profitability
The management of financial, general and administrative elements involved in the conduct of our business and ownership or operation of our vessels requires the following main components:

● management of our financial resources, including banking relationships, i.e., administration of bank loans and bank accounts;

● management of our accounting system and records and financial reporting;

● administration of the legal and regulatory requirements affecting our business and assets; and

● management of the relationships with our service providers and customers; and

● general and administrative expenses.

The principal factors that affect our profitability, cash flows and shareholders' return on investment include:

● charter rates and periods of charter hire for our tanker vessels;

● utilization of our tanker vessels (earnings efficiency);

● levels of our tanker vessels' operating expenses and drydocking costs;

● depreciation and amortization expenses;

● financing costs; and

● fluctuations in foreign exchange rates.

● **Revenue** decreased by $49.0 million to $174.1 million in the six-month period ended June 30, 2025, from $223.1 million in the six-month period ended June 30, 2024. This decrease is mainly associated with the decrease in fleetwide Daily TCE Rate to $44,529 in the six-month period ended June 30, 2025, from $64,254 in the six-month period ended June 30, 2024. Please refer to "Performance Indicators" for the definition and reconciliation of this measure to Revenue, the most directly comparable financial measure calculated and presented in accordance with International Financial Reporting Standards ("IFRS").

● **Voyage expenses** decreased by $1.1 million to $61.5 million in the six-month period ended June 30, 2025, compared to $62.6 million in the six-month period ended June 30, 2024. The decrease is attributable to a decrease in bunker expenses, mainly attributable to the lower bunker consumption as a result of fewer off hire days.

● **Vessel operating expenses** increased by $0.6 million to $24.3 million in the six-month period ended June 30, 2025, compared to $23.7 million in the six-month period ended June 30, 2024. The increase was mainly due to higher maintenance costs.

● **General and administrative expenses** increased by $0.8 million to $8.5 million in the six months ended June 30, 2025, compared to $7.7 million in the six months ended June 30, 2024. The increase represents increased costs associated with our U.S. listing (recurring costs), shore-based employee costs and other administrative expenses.

● **Interest and finance costs** decreased by $4.5 million to $24.2 million in the six months ended June 30, 2025, compared to $28.7 million in the same period of 2024. The decrease is mainly due to a decrease in average indebtedness, including deferred financing fees, from $668.8 million in the six months ended June 30, 2024, to $630.9 million in the six months ended June 30, 2025.

● We recorded a **profit** of $39.4 million in the six-month period ended June 30, 2025, or $1.23 per basic and diluted share, compared to a profit of $81.1 million, or $2.52 per basic and diluted share in the same period in 2024. The decrease is primarily due to lower revenues generated from operations.

#### Performance Indicators

#### Daily TCE Rate
The figures shown below are financial and non-financial statistical metrics used by management to measure performance of our vessels. For the "Fleet Data" figures there are no comparable GAAP or IFRS measures.

[**Table of Contents**](#TOC)

In the shipping industry, economic decisions are based on vessels' deployment upon anticipated Daily TCE Rates, and industry analysts typically measure shipping freight rates in terms of Daily TCE Rates. This is because under time-charter and bareboat contracts the customer usually pays the voyage expenses, while under voyage charters the ship-owner usually pays the voyage expenses, which typically are added to the hire rate at an approximate cost. In a voyage charter contract, consideration is received for the use of a vessel between designated ports for the duration of the voyage only, at an agreed upon rate per volume of cargo carried. In a time charter contract, the customer (also known as the charterer) is responsible to pay for fuel consumed and port expenses incurred during the agreed period of time. In a voyage charter contract, the Company is responsible for maintaining the voyage, including vessel scheduling and routing, as well as any related voyage expenses, such as fuel, port and other expenses. Under voyage charters, the majority of voyage expenses are generally borne by us, whereas for vessels in a time charter, such expenses are borne by the charterer. In a bareboat charter, the customer pays for all of the vessel's operating expenses, and undertakes to maintain the vessel in a good state of repair and efficient operating condition and drydock the vessel during this period as per the classification society requirements. We may incur voyage related expenses when positioning or repositioning vessels before or after the period of a time or other charter, during periods of commercial waiting time or while off-hire during drydocking or due to other unforeseen circumstances. Because of the different nature of these types of arrangements, the amount of revenues earned by the Company can differ significantly between them.

Consistent with industry practice, we use the Daily TCE Rates and time charter equivalent revenue because it provides a means of comparison between different types of vessel employment and, therefore, assists in evaluating their financial performance and in our decision-making process regarding the deployment and use of our vessels and in evaluating our financial performance. The Daily TCE Rate and time charter equivalent revenue is each a non-GAAP and non-IFRS measure. We believe the Daily TCE Rate and time charter equivalent revenue provides additional meaningful information in conjunction with Revenue, the most directly comparable GAAP and IFRS measure, because it assists our management in making decisions regarding the deployment and use of our vessels and in evaluating their financial performance. The Daily TCE Rate and time charter equivalent revenue are measures used to compare period-to-period changes in a company's performance and management believes that the Daily TCE Rate and time charter equivalent revenue provide meaningful information to our investors.

In evaluating our financial condition, we focus on the below measures to assess our historical operating performance and we use future estimates of the same measures to assess our future financial performance. In assessing the future performance of our fleet, the greatest uncertainty relates to future charter rates at the expiration of a vessel's present period employment, whether under a time charter or a bareboat charter. Decisions about future purchases and sales of vessels are based on the availability of excess internal funds, the availability of financing and the financial and operational evaluation of such actions and depend on the overall state of the shipping market and the availability of relevant purchase candidates.

The following table sets forth our computation of Daily TCE Rates and time charter equivalent revenue, including a reconciliation of revenues to the Daily TCE Rates (unaudited) and time charter equivalent revenue (unaudited) for the periods presented:

#### Daily Opex
Daily Opex per vessel is an alternative performance measure that provides meaningful information to our management with regards to our vessels' efficiency and deployment. Daily Opex is not a measure under generally accepted accounting principles (i.e., it is a non-GAAP measure) or IFRS and should not be considered as an alternative to any measure of expenses and financial performance presented in accordance with IFRS. Our reconciliation of Daily Opex, including management fees, may differ from that reported by other companies. We believe Daily Opex provides additional meaningful information in conjunction with Vessel operating expenses, the most directly comparable GAAP and IFRS measure, because it provides meaningful information to our investors in evaluating our financial performance.

Daily Opex is calculated as vessel operating expenses and technical management fees divided by calendar days, for the relevant periods

The following table sets forth our reconciliation of Daily Opex (unaudited) for the periods presented:

#### Liquidity and Capital Resources
Since our formation, our principal sources of funds have been funds in the form of equity, debt or working capital provided by operating cash flow and long-term borrowings. Our principal use of funds has been capital expenditures to maintain the quality of our vessels, comply with international shipping standards and environmental laws and regulations, fund working capital requirements, service our debt, and distribute capital to our shareholders.

Our business is capital intensive and its future success will depend on our ability to maintain a high-quality fleet through the acquisition of newer vessels and the selective sale of older vessels. Future acquisitions are subject to management's expectation of future market conditions, our ability to acquire vessels on favorable terms and our liquidity and capital resources. Our ability to continue to meet our liquidity needs is subject to and will be affected by cash generated from operations, the economic or business environment in which we operate, shipping industry conditions, the financial condition of our customers, vendors and service providers, our ability to comply with the financial and other covenants of our indebtedness, and other factors.

In the future, we may require capital to fund acquisitions or to improve or support our ongoing operations and debt structure, particularly in light of economic conditions resulting from geopolitical conflict and wars, including the Russian/ Ukraine conflict and potential hostilities in the Middle East, and general conditions in the tanker market. We may from time to time seek to raise additional capital through equity or debt offerings, selling vessels or other assets, pursuing strategic opportunities, or otherwise. We may also from time to time seek to incur additional debt financing from private or public sector sources, refinance our indebtedness or obtain waivers or modifications to our credit agreements to obtain more favorable terms, enhance flexibility in conducting our business, or otherwise. We may also seek to manage our interest rate exposure through hedging transactions. We may seek to accomplish any of these independently or in conjunction with one or more of these actions. However, if market conditions are unfavorable, we may be unable to accomplish any of the foregoing on acceptable terms or at all.

Our medium- and long-term liquidity requirements relate to the operation and maintenance of our vessels, including covering costs of compliance with existing or future environmental or other regulations, which may be material. Sources of funding for these requirements include cash flows from operations or new debt financings if required.

As of June 30, 2025, we had an indebtedness of $636.1 million, which after excluding unamortized financing fees amounts to a total indebtedness of $630.9 million. As of December 31, 2024, we had an indebtedness of $651.6 million, which after excluding unamortized financing fees amounts to a total indebtedness of $645.6 million.

[**Table of Contents**](#TOC)

As of June 30, 2025, cash and cash equivalent balances amounted to $65.3 million, $5.6 million of which are classified as restricted cash, compared to $54.3 million of which $4.9 million are classified as restricted cash as of December 31, 2024.

As of June 30, 2025 and December 31, 2024, we did not have any material commitments for capital expenditures and we do not expect to have any other requirement or obligation, to which we should allocate capital resources.

Working capital is equal to current assets minus current liabilities, including the current portion of long-term debt. As of June 30, 2025, we had a working capital surplus of $67.0 million, as compared to a surplus of $46.2 million as of December 31, 2024.

The Company's cash flow projections for the period after one year after the date that the financial statements are issued indicate that cash on hand and cash provided by operating activities will be sufficient to cover the liquidity needs that become due in the twelve-month period ending one year after the financial statements' issuance.

As of June 30, 2025, we were in compliance with all of the financial covenants contained in our credit facilities and other financing arrangements that we had entered as at that date. We may seek additional indebtedness to finance future vessel acquisitions in order to maintain our cash position or to refinance our existing debt on more favorable terms.

As of June 30, 2025, we had outstanding borrowings of $636.1 million (including long-term debt and other financial liabilities). Our primary known and estimated liquidity needs for the twelve-month period ending one year after the financial statements' issuance include obligations related to scheduled principal payments of outstanding borrowings and respective interest expenses payments and estimated drydocking expenditures. Additional information on our annual scheduled obligations under our long-term debt and other financial liabilities are described in "Long-Term borrowings" below and in Note 4 of our interim condensed financial statements included below. Generally, we expect that, in addition to the cash generated from our operations, our long-term funding sources will include bank borrowings, lease financings and the issuance of debt and equity securities.

#### Cash Flows
The following table summarizes our cash flows from operating, investing and financing activities for the six months ended June 30, 2025 and 2024:

#### Six months ended June 30, 2025 as compared to six months ended June 30, 2024
● Net cash **provided by operating activities** for the six months ended June 30, 2025, and 2024 was $49.3 million and $125.3 million, respectively. This decrease was mainly related to a $49.0 million decrease in revenues. In addition, movements in working capital items, such as trade receivables, also contributed to the fluctuation in cash flows, primarily due to the general timing of operating cash flows.

● Net cash **used in investing activities** for the six months ended June 30, 2025, was $1.9 million and primarily consisted of $2.0 million paid in connection with scheduled drydocking expenses. Net cash used in investing activities for the six months ended June 30, 2024, was $1.3 million and primarily consisted of $2.7 million paid in connection with scheduled drydocking expenses, partially offset by $1.8 million received from interest.

● Net cash **used in financing activities** for the six months ended June 30, 2025, and 2024 was $38.1 million and $80.7 million, respectively. The decrease was primarily driven by lower distributions paid to shareholders of $21.6 million in 2025 compared to $56.7 million in the same period in 2024, as well as lower net debt outflows of $15.6 million in the six months ended June 30, 2025 compared to $23.1 million in the same period in 2024.

On May 23, 2022, we, through two of our vessel-owning subsidiaries, Anassa Navigation S.A. and Nellmare Marine Ltd., entered into an approximately $125.7 million secured term loan facility with the National Bank of Greece to refinance the then-existing indebtedness on our vessels, *Nissos Kythnos* and *Nissos Donoussa*, which agreement we amended on June 29, 2023 to amend the provisions in relation to the calculation of interest from LIBOR to Term SOFR, subject to the borrowers' option to switch the interest rate to the cumulative compounded SOFR. The facility has a final maturity date of May 25, 2029 and bears interest at SOFR (previously LIBOR) plus a margin of (originally) 2.50% per annum. The margin may be increased following discussions between the lender and the borrowers if it is determined that, pursuant to the sustainability certificate provided by ourselves to the lender annually, (1) the weighted average of the efficiency ratio of all fleet vessels (using the parameters of fuel consumption, distance travelled and deadweight at maximum summer draught, reported in unit grams of CO<sup>2</sup> per ton per mile) for that calendar year, as certified by an approved classification society, is equal to or above the target set for the relevant year and (2) the weighted average percentage of the total waste incinerated on board for all fleet vessels in that calendar year (calculated in line with Class Approved Plans & Record Books, MARPOL Annex I — "Oil Record Book" (endorsed by Flag Administration) & "Fuel Management Plan" (approved by class) and MARPOL Annex V — "Garbage Record Book" & "Garbage Management Plan" (approved by class)) is equal to or above the target set for the relevant year. The amount of any increase in the margin will be based on discussions between the lender and the borrowers. Other than as set out above, there will be no other assessment of the information contained in any sustainability certificate and the sustainability certificates themselves will not be made publicly available unless we deem them to be material. Each of the two tranches of the facility is repayable in 28 quarterly installments, the first 8 of which are $750,000 and the next 20 of which are $850,000, with a balloon payment of $39,835,000 due upon maturity. This facility was originally secured by, among other things, a first priority mortgage on each of *Nissos Kythnos* and *Nissos Donoussa* and is guaranteed by us. The tranche relating to the *Nissos Kythnos* was repaid by us on May 24, 2024.

On May 21, 2024, we entered into a supplemental agreement to the existing senior secured credit facility financing the VLCC vessel Nissos Donoussa. The supplemental agreement provides for a reduction of the margin to 165 basis points over the applicable Term SOFR, through the duration of the facility.

The Nissos Kythnos New Facility is priced at 140 basis points over the applicable Term SOFR, until December 2026. Thereafter, a new applicable margin will be mutually agreed between the parties, for the remaining duration of the facility, which matures in six years. If the parties do not agree to a new applicable margin, the Company will have the ability to prepay the facility at no additional cost. The facility will be repaid in quarterly instalments of approximately $1.041 million each, together with a balloon installment of approximately $35.024 million payable at maturity, is secured by, among other things, security over the *Nissos Kythnos*, and is guaranteed by us. The facility also includes a sustainability linked margin adjustment provision, starting in 2025, whereby the applicable margin may decrease or increase by 5 basis points per year, subject to the Company meeting certain sustainability linked targets.

#### Dividend Policy
The declaration, timing and amount of any dividend is subject to the discretion of our board of directors and will be dependent upon our earnings, financial condition, market prospects, capital expenditure requirements, investment opportunities, restrictions in our loan agreements, the provisions of the Marshall Islands law affecting the payment of dividends to shareholders, overall market conditions and other factors. Subject to these limitations, we seek to offer our shareholders with a competitive yield which is reflective of the cash flows generated by us, and currently intend to pay dividends in an amount depending on and taking into consideration the amount of our net profits, after adjusting for non-recurring items, working capital needs, our capital structure and other discretionary items as our board of directors decides, from time to time. We define "net profits" as the profit for the relevant period, as disclosed in the Company's published consolidated statement of profit or loss and other comprehensive income. We have no written dividend policy and are able to adopt, amend, change or terminate any dividend policy in the future.

We can provide no assurance that dividends will be paid in the future and there may be a high degree of variability from period to period in the amount of cash, if any, that is available for the payment of dividends. Please see the section entitled "Item 3.D. Risk Factors — Risks Related to our Common Shares — Our ability to declare and pay dividends to holders of our common shares will depend on a number of factors and will always be subject to the discretion of our board of directors" in our 2024 Annual Report.

Since we are a holding company with no material assets other than the shares of our subsidiary and affiliates through which we conduct our operations, our ability to pay dividends will depend on our subsidiary and affiliates distributing to us their earnings and cash flow. Our financing arrangements impose certain limitations on our ability to pay dividends and our subsidiaries' ability to make distributions to us. Please see the section entitled "Item 5.B. Liquidity and Capital Resources — Credit Facilities and Financing Obligations — Loan Covenants" in our 2024 Annual Report for further information.

**2.**General accounting principles

#### Basis of preparation and statement of compliance
These unaudited condensed consolidated financial statements have been prepared in accordance with International Accounting Standard ("IAS") 34 Interim Financial Reporting as issued by the International Accounting Standards Board ("IASB"). These financial statements and the accompanying notes should be read in conjunction with the Company's annual report on Form 20-F for the fiscal year ended December 31, 2024 (the "2024 Annual Report").

The unaudited condensed consolidated financial statements are expressed in United States Dollars ($), since this is the currency in which the majority of the Group's transactions are denominated. The interim consolidated financial statements have been prepared on the historical cost basis, except for derivative financial instruments, measured at their fair value. The carrying amounts reflected in the consolidated statement of financial position for cash and cash equivalents, restricted cash, trade and other receivables, receivable claims, and other current liabilities, approximate their respective fair values due to the relatively short-term maturity of these financial instruments.

These unaudited interim condensed consolidated financial statements have been prepared on the same basis as the annual financial statements. Operating results for the six-month period ended June 30, 2025 are not necessarily indicative of the results that might be expected for the fiscal year ending December 31, 2025.

#### Summary of Material Accounting Policies
A discussion of the Group's Material Accounting Policies can be found in the consolidated financial statements for the year ended December 31, 2024, included in the 2024 Annual Report. There have been no material changes to these policies in the six-month period ended June 30, 2025.

#### Application of new and revised International Financial Reporting Standards

#### Standards and interpretations adopted in the current period
There were no IFRS standards or amendments that became effective in the current year which were relevant to the Group or material with respect to the Group's financial statements.

#### Standards and amendments in issue not yet adopted.
At the date of authorization of these consolidated financial statements, the following standards and amendments relevant to the Group were in issue but not yet adopted:

In April 2024, the International Sustainability Standards Board ("ISSB") issued IFRS 18. IFRS 18 includes requirements for all entities applying IFRS for the presentation and disclosure of information in financial statements. IFRS 18 is effective for annual reporting periods beginning on or after January 1, 2027 with earlier application permitted. Management anticipates that this new standard will have a disclosure impact on the Group's financial statements.

On May 30, 2024, the International Accounting Standards Board (IASB) issued 'Amendments to the Classification and Measurement of Financial Instruments (Amendments to IFRS 9 and IFRS 7)' to address matters identified during the post-implementation review of the classification and measurement requirements of IFRS 9 'Financial Instruments'. The amendments are effective for reporting periods beginning on or after January 1, 2026. Management anticipates that this amendment will not have a material impact on the Group's financial statements.

In July 2024, the IASB published 'Annual Improvements to IFRS Accounting Standards — Volume 11'. It contains amendments to five standards as result of the IASB's annual improvements project (IFRS 1 — First-time Adoption of International Financial Reporting Standards, IFRS 7 — Financial Instruments: Disclosures, IFRS 9 — Financial Instruments, IFRS 10 — Consolidated Financial Statements, IAS 7 — Statement of Cash Flows). The amendments are effective for annual reporting periods beginning on or after 1 January 2026, with earlier application permitted. The Group is currently assessing the impacts from the adoption of those five standards.

There are no other IFRS standards and amendments issued by but not yet effective that are expected to have a material effect on the Group's financial statements

[**Table of Contents**](#TOC)

#### Financial risk factors
The Group's activities expose it to a variety of financial risks: credit risk, market risk, currency risk, interest risk and liquidity risk. Since the interim condensed consolidated financial statements do not include all financial risk management information and disclosures required in the annual financial statements, they should be read in conjunction with the Company's annual financial statements for the year ended December 31, 2024 included in the 2024 Annual Report.

There have been no significant changes in any other risk management policies since December 31, 2024.

As of June 30, 2025, the charter-free market value of all our vessels exceeded their carrying value. Thus, no recoverable amount test was deemed necessary to be performed for any of our vessels.

The Group has pledged the above vessels to secure its loan facilities (see also Note 4).

On March 21, 2022, we, through two of our subsidiaries, Ark Marine S.A. and Theta Navigation Ltd, entered into an approximate $145.5 million sale and leaseback agreements with CMB Financial Leasing Co., Ltd. ("CMBFL"), with respect to our vessels, *Nissos Kea* and *Nissos Nikouria*. On June 29, 2023 and on January 26, 2024, respectively, we entered into amendment and restatement agreements of each bareboat charter to amend certain provisions of the bareboat charters. The charter period for each of the vessels was 84 months from December 31, 2023 (with respect to *Nissos Kea*) and March 3, 2024 (with respect to *Nissos Nikouria*) and charterhire was payable quarterly as follows: (a) from the delivery date of each vessel and up to and including December 31, 2023 (with respect to *Nissos Kea*) and March 3, 2024 (with respect to the *Nissos Nikouria)*, a fixed amount equal to $909,375 plus a variable amount by priced at 260 basis points (being 2.45% as margin and 0.15% as CAS) over the applicable three-month Term SOFR, and (b) following December 31, 2023, with respect to *Nissos Kea*, and March 3, 2024, with respect to the *Nissos Nikouria*, a fixed amount equal to $909,375 plus a variable amount priced at 200 basis points over the applicable three-month Term SOFR. The first part of the sale and leaseback relating to the delivery of *Nissos Kea* was drawn on March 31, 2022 and was scheduled to mature on the date falling 84 months from December 31, 2023 and the second part of the sale and leaseback relating to the delivery of *Nissos Nikouria* was drawn on June 3, 2022 and was scheduled to mature on the date falling 84 months from March 3, 2024. According to each bareboat charter, the Company had a purchase option that could be exercised annually as from December 31, 2024 (with respect to *Nissos Kea*) and March 3, 2025 (with respect to *Nissos Nikouria*). If the purchase option date fell after the first but prior to the seventh anniversary of December 31, 2023 (with respect to *Nissos Kea*) and March 3, 2024 (with respect to *Nissos Nikouria*), the purchase option price for the relevant vessel was an amount equal to the opening capital balance i.e., $72,750,000 amount drawn per vessel (75% of the purchase price) minus charterhire paid (the "owner's costs"), plus (a) accrued but unpaid charterhire, (b) breakfunding costs including any swap costs, (c) legal and other documented costs of the owner to sell the relevant vessel, and any other additional amounts due under the sale and leaseback documentation. If the purchase option date fell on the seventh anniversary of December 31, 2023 (with respect to *Nissos Kea*) and March 3, 2024 (with respect to *Nissos Nikouria*), the purchase option price for the relevant vessel was an amount equal to $40,921,875 (the "amended owner's costs"), plus (a) accrued but unpaid charterhire, (b) and other documented costs of the owner to sell the relevant vessel, and (c) any other additional amounts due under the sale and leaseback documentation. Each charter was guaranteed by Okeanis Eco Tankers Corp., Ark Marine S.A. and Theta Navigation Ltd, as applicable, and we have permitted a mortgage to be filed regarding the finance lease (no mortgage on either vessel has been registered) as well as entered into an account charge, general assignment, pledge of shares of the bareboat charterer, a builder's warranties assignment, and a manager's undertaking. We repurchased the Nissos Nikouria and Nissos Kea in June 2025, and therefore this sale and leaseback arrangement is no longer in effect.

On May 23, 2022, we, through two of our vessel-owning subsidiaries, Anassa Navigation S.A. and Nellmare Marine Ltd., entered into an approximately $125.7 million secured term loan facility with the National Bank of Greece to refinance the then-existing indebtedness on our vessels, Nissos Kythnos and Nissos Donoussa, which agreement we amended on June 29, 2023 to amend the provisions in relation to the calculation of interest from LIBOR to Term SOFR, subject to the borrowers' option to switch the interest rate to the cumulative compounded SOFR. The facility had a final maturity date of May 25, 2029 and beared interest at SOFR (previously LIBOR) plus a margin of 2.50% per annum. This facility was secured by, among other things, a first priority mortgage on the Nissos Donoussa and was guaranteed by us. The tranche relating to the Nissos Kythnos was repaid by us on May 24, 2024.

On May 21, 2024, we entered into a supplemental agreement to the existing senior secured credit facility financing the VLCC vessel Nissos Donoussa. The supplemental agreement provided for a reduction of the margin to 165 basis points over the applicable Term SOFR, through the duration of the facility.

On June 17, 2025, we entered into a new $65.0 million senior secured credit facility to finance the option to purchase back the VLCC vessel *Nissos Kea* (the "Nissos Kea New Facility"). The Nissos Kea New Facility is priced at 135 basis points over the applicable Term SOFR, and matures in seven years, and will be repaid in 28 equal consecutive quarterly instalments of approximately $0.9 million each, together with a balloon instalment of approximately $39.8 million payable at maturity. The Nissos Kea New Facility is secured by, among other things, security over the *Nissos Kea*, and is guaranteed by the Company. The facility was drawn on June 26, 2025.

On May 8, 2025, we entered into a new $130.0 million senior secured credit facility with a prominent Greek bank to finance the option to purchase back the VLCC vessels *Nissos Nikouria* and *Nissos Anafi*. (the "New Nikouria and Anafi Facility"). The New Nikouria and Anafi Facility consists of two Advances, Advance A of $66.0 million for the vessel *Nissos Nikouria* and Advance B of $64.0 million for the vessel *Nissos Anafi*. The New Nikouria and Anafi Facility is priced at 140 basis points over the applicable Term SOFR, matures in seven years. Advance A and Advance B will be repaid in 28 equal consecutive quarterly instalments of approximately $0.9 million and $1.0 million, respectively, together with a balloon instalment of approximately $40.8 million and $36.0 million , respectively, payable at maturity. Advance A was drawn on May 29, 2025, and Advance B was drawn on July 31, 2025. The New Nikouria and Anafi Facility is secured by, among other things, security over the *Nissos Nikouria* and *Nissos Anafi*, and is guaranteed by the Company.

According to IFRS 9 "Financial Instruments", the amendments to the bareboat charter agreements with CMBFL relating to the *Nissos Kea* and *Nissos Nikouria*, together with the supplemental agreement with NBG, were considered modifications of existing loans, which resulted in the recognition of a modification gain of $1.8 million, which amount has been included in the Company's statement of profit or loss and other comprehensive income for the six months of 2024. The loan with CMBFL relating to the Nissos Kea and Nissos Nikouria has been refinanced and as a result the unamortized balance of modification loss of $1.1 million was written off and was included in Loss on debt extinguishment in the statement of profit or loss and other comprehensive income.

As at June 30, 2025, the loans' fair values approximate their carrying values.
