Insights

Maritime equity analyst

Solid H1 2025 profitability with strong liquidity and backlog.

Euroseas lifted time charter revenue to $116.8M on a larger fleet, while average TCE of $28,468 remained healthy despite a year-over-year dip. Operating income rose to $73.9M, supported by a $10.2M vessel sale gain, driving net income to $66.8M and basic EPS of $9.63.

Cash generation was robust with operating cash flow of $68.5M and period-end cash and restricted cash of $112.7M. Debt stood at $229.4M, with $21.2M scheduled within the next 12 months, and documented margins of 1.80%–2.295% over SOFR. Contract coverage was meaningful with future minimum charter revenues of $393.2M.

Notable events include delivery of two eco-design vessels in January 2025, planned sale of M/V “Marcos V” at $50.0M (deposit received), and two additional 4,300 TEU newbuilds signed on July 29, 2025 for about $118.5M. Dividend payments and share repurchases were executed, balancing growth and shareholder returns.

(1) For the definition of calendar days, available days, voyage days and utilization rate see our annual report on Form 20-F for the year ended December 31, 2024 (“Item 5A-Operating Results.”) filed on May 15, 2025.

(2) Time charter equivalent rate, or average TCE rate, is a measure of the average daily net revenue performance of our vessels and is determined by dividing time charter revenue and voyage charter revenue, if any, gross of commissions, net of voyage expenses, or time charter equivalent revenues, or TCE revenues, by the number of voyage days during the relevant time period. Voyage expenses primarily consist of port, canal and fuel costs that are unique to a particular voyage, which would otherwise be paid by the charterer under a time charter contract, or are related to repositioning the vessel for the next charter. TCE revenues, a non-GAAP measure, provides additional meaningful information in conjunction with time charter revenue and voyage charter revenue, the most directly comparable GAAP measure, because it assists the Company’s management in making decisions regarding the deployment and use of its vessels and because we believe it provides useful information to investors regarding the Company's financial performance. TCE revenues and TCE rate are also standard shipping industry performance measures used primarily to compare period-to-period changes in a shipping company's performance despite changes in the mix of charter types (i.e., spot voyage charters, time charters, pool agreements and bareboat charters) under which the vessels may be employed between the periods (see also “Item 5A-Operating Results” in our annual report on Form 20-F for the year ended December 31, 2024). Our definition of TCE revenues and TCE rate may not be comparable to that used by other companies in the shipping industry.

(3) We calculate daily total operating expenses excluding drydocking expenses by dividing total operating expenses excluding drydocking expenses for the relevant period by calendar days for such period. We calculate total vessel operating expenses as the sum of vessel operating expenses, related party management fees and general and administrative expenses. This measure assists our management and investors by increasing the comparability of our performance from period to period. Drydocking expenses include costs of shipyard, paints and agent expenses, which costs may vary from period to period.

The following table reflects the reconciliation of TCE revenues to time charter revenue and voyage charter revenue, if any, as reflected in the unaudited condensed consolidated statements of comprehensive income and our calculation of average TCE for the periods presented.

Six months ended June 30, 2025 compared to six months ended June 30, 2024.

Time charter revenue. Time charter revenue for the six-month period ended June 30, 2025 was $116.8 million, increased compared to the same period in 2024 during which time charter revenue amounted to $108.6 million. The increase in time charter revenue was mainly due to the increased average number of vessels operating in the first six months of 2025 compared to the same period of 2024. While employed, our vessels generated an average TCE rate of $28,468 per day per vessel in the first six months of 2025, compared to $29,836 per day per vessel for the same period in 2024 (see calculation in the table above). An average of 22.83 vessels operated in the six months of 2025 for a total of 4,133 calendar days as compared to an average of 20.43 vessels during the same period in 2024 or 3,720 calendar days, a 11.1% increase in terms of calendar days. Our voyage days, reflecting the number of days our fleet earned revenue, increased by 13.1% to 4,085.3 days in the first six months of 2025 from 3,613.1 days in the same period in 2024. During the first six months of 2025, we had 29.8 scheduled off-hire days, nil commercial off-hire days and 17.9 operational off-hire days compared to 99.3 scheduled off-hire days, 3.7 commercial off-hire and 3.9 operational off-hire days in the first six months of 2024.

Commissions. Commissions for the six-month period ended June 30, 2025 amounted to $3.2 million, at 2.8% of time charter revenues, as compared to $3.1 million for the same period of 2024. The percentage of commissions over revenues was marginally lower in the six month period of 2025 than in the same period of 2024 during which they amounted to 2.9% over revenues. The overall level of commissions depends on the agreed commission for each charter contract.

Voyage expenses. Voyage expenses for the six-month period ended June 30, 2025 were $0.5 million compared to $0.8 million for the same period of 2024. Voyage expenses for the six-month period of 2025 related to expenses for repositioning of our vessels between time charters and owners expenses at certain ports. For the same period of 2024 voyage expenses also include bunkers consumption by four of our vessels (M/V “Synergy Antwerp”, M/V “Synergy Oakland”, M/V “Synergy Keelung” and M/V “Marcos V”) during their drydock period partly offset by a gain on bunkers from the sale of M/V “EM Astoria”. Voyage expenses depend on the number of days our vessels are sailing for repositioning and any port or other costs incurred without a contract. Our vessels are generally chartered under time charter contracts. Voyage expenses usually represent a small fraction (0.7% and 0.4% in each of the first six months of 2024 and 2025) of charter revenues.

Vessel operating expenses. Vessel operating expenses were $23.7 million during the first six months of 2025 compared to $22.5 million for the same period of 2024. Daily vessel operating expenses decreased between the two periods to $5,742 per day per vessel in the first six months of 2025 compared to $6,051 per day during the same period of 2024, a 5.1% decrease mainly attributable to the significantly lower daily operating costs of the new building vessels delivered to the Company gradually within the past two years.

5

Drydocking expenses. These are expenses we pay for our vessels to complete a drydocking as part of an intermediate or special survey or, in some cases, an in-water survey in lieu of a drydocking. The cost of passing a survey increases significantly if a dry-docking is required and depends on the extent of work that needs to be performed (such as amount of steel replacement required), the location of the drydock yard and whether it is an intermediate or a special survey with the latter almost always requiring a drydocking and more extensive work. In the first six months of 2025, three of our vessels completed extensive repairs afloat for a total cost of approximately $3.5 million. During the first six months of 2024, four of our vessels completed their special survey with drydock for a total cost of $7.2 million. 

Vessel depreciation. Vessel depreciation for the six-month period ended June 30, 2025 was $15.3 million. Comparatively, vessel depreciation for the six-month period ended June 30, 2024 amounted to $12.3 million. This increase was due to the higher average number of vessels operating in the first six months of 2025 compared to the same period of 2024.

Related party management fees. These are part of the fees we pay to Eurobulk Ltd. (“Eurobulk” or the “Manager”) under our Master Management Agreement. During the first six months of 2025, Eurobulk charged us 840 Euros per day per vessel totaling $3.9 million for the period, or $946 per day per vessel. In the same period of 2024, management fees amounted to $3.3 million, or $875 per day per vessel based on the daily rate per vessel of 810 Euros. The increase in the total management fees is primarily due to the higher number of vessels operating during the first six months of 2025 compared to the same period of 2024 and the adjustment for inflation in the daily vessel management fee, effective from January 1, 2025, increasing it from 810 Euros to 840 Euros.  

Other operating income. During the six-month period ended June 30, 2025, other operating income amounted to $0.12 million, relating to loss of hire insurance received for one of our vessels. No such case existed in the first six months of 2024.

General and administrative expenses. These expenses include the fixed portion of our management fees, incentive awards, legal and audit fees, directors’ and officers’ liability insurance, and other miscellaneous corporate expenses. In the first six months of 2025, we incurred a total of $3.2 million of general and administrative expenses, as compared to $2.4 million for the same period of 2024. The increase in the general and administrative expenses is primarily due to increased professional fees and increased costs for our stock incentive plan.

Gain on sale of vessel. The results of the Company for the first half of 2025 include a $10.2 million gain on the sale of M/V “Diamantis” that was completed in January 2025.The results of the Company for the first half of 2024 include a $5.7 million gain on the sale of M/V “EM Astoria” that was completed in June 2024.

Interest and other financing costs. Total interest and other financing costs for the first half of 2025 amounted to $7.9 million. Capitalized interest charged on the cost of our newbuilding program was $0.1 million for the first six months of 2025. For the same period of 2024 interest and other financing costs were $3.9 million. Capitalized interest charged on the cost of our newbuilding program was $2.6 million for the same period of 2024. This increase is due to the increased amount of debt in the current period compared to the same period of 2024. For the six-month period ended June 30, 2025, our weighted average outstanding debt was approximately $243 million compared to a weighted average outstanding debt of approximately $165 million for the six-month period ended June 30, 2024.The weighted average benchmark rate on our bank debt for the six-month period ended June 30, 2025 was 4.4%, while the weighted average margin over the benchmark rate was 2.1% for a total weighted average interest rate of 6.5% per annum as compared to a weighted average benchmark rate for the six month period ended June 30, 2024 of 5.3%, and a weighted average margin over the benchmark rate of 2.3% for a total weighted average interest rate of 7.6% per year.

Gain / (loss) on derivative, net. In the first six months of 2025, the Company recognized a $0.3 million unrealized loss and a $0.1 million realized gain on one interest rate swap, as compared to a $0.8 million unrealized gain and a $0.2 million realized gain on one interest rate swap in the first six months of 2024.

6

Interest income. Interest income amounted to $1.1 million for the first six months of 2025 compared to $0.9 million interest income for the same period in 2024, mainly as a result of the higher amounts of our fixed deposits.

Net income. As a result of the above, net income for the six months ended June 30, 2025 amounted to $66.8 million compared to a net income of $60.8 million for the same period in 2024.

Liquidity and capital resources

Historically, our sources of funds have been equity provided by our shareholders, operating cash flows, long-term borrowings and proceeds from vessel sales. Our principal use of funds has been capital expenditures to establish and expand our fleet, maintain the quality of our vessels during operations and the periodically required drydockings, comply with international shipping standards and environmental laws and regulations, fund working capital requirements and, if necessary, operating shortfalls, make principal repayments on outstanding loan facilities, and pay dividends.

Our short-term liquidity requirements include paying operating expenses, funding working capital requirements, interest and short-term principal payments on outstanding debt, repurchasing common shares under our share repurchase program, funding payments for vessels under construction and maintaining cash reserves to strengthen our position against adverse fluctuations in operating cash flows. Our primary source of short-term liquidity is cash generated from operating activities, available cash balances and portions from debt and equity financings.

Our long-term liquidity requirements are funding the equity portion of vessel acquisitions and vessels under construction, debt repayment and payment of cash dividends when declared. Sources of funding for our long-term liquidity requirements include cash flows from operations, bank borrowings, issuance of debt and equity securities, and vessel sales.

Our total cash and cash equivalents and restricted cash at June 30, 2025 were $112.7 million, an increase of $32.0 million from $80.7 million at December 31, 2024. We hold cash and cash equivalents primarily in U.S. Dollars, with a minor balance held in Euros. We conduct our funding and treasury activities based on corporate policies designed to minimize borrowing costs and maximize investment returns while maintaining the safety of the funds and appropriate levels of liquidity for our purposes.

On June 28, 2024, the Company signed two contracts for the construction of two eco-design fuel efficient containerships. The vessels will have a carrying capacity of about 4,300 teu each and will be built at Jiangsu Yangzi Xinfu Shipbuilding CO., Ltd., in China. The two newbuildings are scheduled to be delivered in the fourth quarter of 2027. The total contracted consideration for these two newbuilding contracts is approximately $120.5 million. For the year ended December 31, 2024 the Company paid $18.1 million, related to shipyard installments for the construction of these two vessels.

As of June 30, 2025, an amount of approximately $102.4 million is payable to the shipbuilding yard until the delivery of the two newbuilding vessels mentioned above $30.1 million of which is due in the period ending June 30, 2027 and $72.3 million is due in the period ending June 30, 2028.

On July 29, 2025, the Company signed two contracts for the construction of two additional eco-design fuel efficient containerships. The vessels will have a carrying capacity of about 4,300 teu each and will be built at Jiangsu Yangzi Xinfu Shipbuilding CO., Ltd., in China. The two newbuildings are scheduled to be delivered in the second quarter of 2028. The total contracted consideration for these two newbuilding contracts is approximately $118.5 million and it will be gradually paid until the vessels’ delivery in the second quarter of 2028 (see Note 15).

All the payments are guaranteed by the Company. The Company intends to finance the cost of all the abovementioned newbuilding contracts with a combination of own cash and debt.

We believe that our current cash balance and our operating cash flows to be generated over the short-term period will be sufficient to meet our known short-term and long-term liquidity needs, including funding the operations of our fleet, capital expenditure requirements and any other present financial requirements.

Cash Flows 

As of June 30, 2025, we had a working capital surplus of $110.4 million. For the six-month period ended June 30, 2025, we reported a net income of $66.8 million and generated net cash from operating activities of $68.5 million. Our cash balance amounted to $100.5 million and cash in restricted and retention accounts amounted to $12.2 million as of June 30, 2025. Included within this $12.2 million is an amount of $5 million held in an escrow account in relation to the anticipated sale of vessel Marcos V, which was completed on October 20, 2025.

Net cash from operating activities.

Our cash flow surplus generated by operating activities for the six months ended June 30, 2025 was $68.5 million as compared to a cash flow surplus of $59.4 million in the six months ended June 30, 2024.

The major driver of the change of cash flows from operating activities for the period ended June 30, 2025 compared to the period ended June 30, 2024 is the increase in net revenue to $113.6 million for the six-month period ended June 30, 2025 from $105.4 million for the corresponding period in 2024, which was also reflected in our net income (excluding non-cash items) of $71.0 million for the period ended June 30, 2025 compared to a net income (excluding non-cash items) of $65.0 million for the corresponding period in 2024.

Net cash from investing activities.

Net cash flows used in investing activities were $39.2 million for the period ended June 30, 2025, compared to $114.9 million for the same period of 2024. The net decrease in cash flows used in investing activities of $75.7 million in the six month period ended June 30, 2025 compared to the six-month period ended June 30, 2024, is mainly attributable to a decrease of $65.4 million in payments related to vessels under construction, an increase of $2.7 million in the proceeds from vessel sales, a $5.0 million increase in the advances received from a vessel held for sale and a decrease of $2.6 million to the cash paid for vessel improvements.

Net cash from financing activities.

Net cash flows provided by financing activities were $2.7 million for the six months ended June 30, 2025, compared to net cash inflows of $67.5 million for the six months ended June 30, 2024. The net decrease in cash flows provided by financing activities of $64.8 million in the six month period ended June 30, 2025 compared to the six-month period ended June 30, 2024, is mainly attributable to the following: (i) a decrease by $41.2 million in loan proceeds, net of loan arrangement fees paid, (ii) an increase by $12.9 million in debt principal payments, (iii) an increase by $13.1 million in cash retained by a spun off company and (iv) an increase in cash paid for share repurchase by $1.3 million counterbalanced by the decrease in the dividends paid by $3.8 million.

Debt Financing

We operate in a capital-intensive industry, which requires significant amounts of investment, and we fund a portion of this investment through long-term debt. We target debt levels we consider prudent at the time of conclusion of such debt funding based on our market expectations, cash flow, interest coverage and percentage of debt to capital amongst other factors.

As of June 30, 2025, we had seven outstanding bank loans and one sale and lease back financing transaction with a combined outstanding balance of $229.4 million. These loans mature between 2027 and 2034. Our long-term debt as of June 30, 2025 comprises debt granted to our vessel-owning subsidiaries with margins over SOFR ranging from 1.80% to 2.295%. A description of our loans as of June 30, 2025 is provided in Note 8 of our attached unaudited interim condensed consolidated financial statements. As of June 30, 2025, we are scheduled to repay approximately $21.2 million of the above loans in the following twelve months.

1. Basis of Presentation and General Information

Euroseas Ltd. was formed on May 5, 2005 under the laws of the Republic of the Marshall Islands to consolidate the beneficial owners of certain ship-owning companies. Euroseas Ltd., through its wholly owned vessel owning subsidiaries (collectively the "Company" or “Euroseas”) is engaged in the ocean transportation of containers through ownership and operation of containerships. Euroseas’ common shares trade on the Nasdaq Capital Market under the ticker symbol “ESEA”.

The operations of the vessels are managed by Eurobulk Ltd. (“Eurobulk” or “Management Company” or “Manager”), a corporation controlled by members of the Pittas family. Eurobulk has an office in Greece located at 4 Messogiou & Evropis Street, Maroussi, Greece. The Manager provides the Company with a wide range of shipping services such as technical support and maintenance, insurance consulting, chartering, financial and accounting services and executive management services, in consideration for fixed and variable fees (see Note 6).

The Pittas family is the controlling shareholder of Friends Investment Company Inc., Containers Shareholders Trinity Ltd., Eurobulk Marine Holdings Inc. and Family United Navigation Co., which, in turn, collectively own 57.8% of the Company’s shares as of June 30, 2025.

The accompanying unaudited condensed consolidated financial statements include the accounts of Euroseas Ltd., and its wholly owned vessel owning subsidiaries and should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2024 as filed with the U.S. Securities and Exchange Commission ("SEC") on Form 20-F on May 15, 2025.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (US GAAP) for interim financial information. Accordingly, they do not include all the information and notes required by US GAAP for complete financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments considered necessary for a fair presentation of the Company's financial position, results of operations and cash flows for the periods presented. 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.

On January 3, 2025, the Company announced its intent to spin-off the Company’s older three vessels, M/V “Aegean Express”, M/V “Diamantis P” and M/V “Joanna”, into a separate company, Euroholdings Ltd. (“Euroholdings”), which applied for listing on the NASDAQ Capital Market. The Company contributed the three vessel owning companies to Euroholdings on January 8, 2025 in exchange for 100% of the shares of Euroholdings, which it would then distribute to its shareholders upon the spin-off distribution. Shares of Euroholdings Ltd. were distributed on March 17, 2025 (the “Distribution Date”) to shareholders of record of the Company as of March 7, 2025 (the “Record Date”). The Company’s shareholders received one share of common stock of Euroholdings Ltd. for every two and a half shares of common stock of the Company they owned as of the Record Date. Beginning on March 18, 2025, the common shares of Euroholdings Ltd. began trading on NASDAQ under the symbol “EHLD".

Dear Panel Shipping Ltd. was added as an additional borrower to the existing loan and made available a second tranche of $26.0 million with the purpose to finance part of the construction cost of M/V “Dear Panel” (Hull No. 4251). The drawdown of $26.0 million took place on January 29, 2025. The second tranche is payable in 20 quarterly instalments, the first twelve of $650,000 each and the next eight of $275,000 each. A balloon instalment of $16,000,000 will be paid together with the last installment. The interest rate margin for the second tranche is 1.80% over SOFR. The loan is secured with (i) first priority mortgage over M/V "Dear Panel", (ii) first assignment of earnings and insurance of M/V "Dear Panel" and (iii) other covenants and guarantees similar to the remaining loans of the Company.

The Company’s bank loans are secured with one or more of the following:

● first priority mortgage over the respective vessels on a joint and several basis.

● first assignment of earnings and insurance.

● a corporate guarantee of Euroseas Ltd.

● a pledge of all the issued shares of each borrower.

The bank loan agreements also contain covenants such as minimum requirements regarding the security cover ratio covenant (the ratio of fair value of vessel to outstanding loan less cash in retention accounts), restrictions as to changes in management and ownership of the ship-owning companies, distribution of profits or assets (i.e. not permitting dividend payment or other distributions in cases that an event of default has occurred), additional indebtedness and mortgage of vessels without the lender’s prior consent, sale of vessels, maximum fleet-wide leverage, sale of capital stock of the Company’s subsidiaries, ability to make investments and other capital expenditures, entering in mergers or acquisitions, minimum cash balance requirements and minimum cash retention accounts (restricted cash). The loan agreements also require the Company to make deposits in retention accounts with certain banks that can only be used to pay the current loan installments. Minimum cash balance requirements are in addition to cash held in retention accounts.

These cash deposits amounted to $6,926,823 and $7,175,206 as of December 31, 2024 and June 30, 2025, respectively, and are included in "Restricted cash" under "Current assets" and "Long-term assets" in the unaudited condensed consolidated balance sheets.

9. Commitments and Contingencies

As of June 30, 2025, future gross minimum revenues under non-cancellable time charter agreements total $393.2 million, $208.5 million of which is due in the period ending June 30, 2026, $114.4 million is due in period ending June 30, 2027, $67.9 million is due in period ending June 30, 2028 and $2.4 million is due in the period ending June 30, 2029. In arriving at the future gross minimum revenues, the Company has deducted an estimated one off-hire day per quarter plus estimated off-hire time required for scheduled intermediate and special surveys of the vessels, if applicable. Such off-hire estimate may not be reflective of the actual off-hire in the future. In addition, the actual revenues could be affected by early delivery of the vessel by the charterers or any exercise of the charterers’ options to extend the terms of the charters, which however cannot be estimated and hence not reflected above.

As of June 30, 2025, the Company had under construction two container carriers with a total contracted amount of $120.5 million. As of June 30, 2025 the Company has paid an amount of $18.1 million as part of the instalments of the contracts of the abovementioned vessels, leaving an outstanding amount of approximately $102.4 million, $30.1 million of which is due in the period ending June 30, 2027 and $72.3 million is due in the period ending June 30, 2028. The Company intends to finance these commitments with a combination of own cash and bank debt.

There are no material legal proceedings to which the Company is a party or to which any of its properties are subject, other than routine litigation incidental to the Company's business. In the opinion of the management, the disposition of these lawsuits should not have a material impact on the consolidated results of operations, financial position and cash flows.

As of June 30, 2025 the unvested restricted shares accrued dividends of $237,245, presented as “Accrued dividends” in the unaudited condensed consolidated balance sheet. As unvested restricted share grantees accrue dividends on awards that are expected to vest, such dividends are charged to retained earnings.

11. Earnings Per Share

Basic and diluted earnings per common share is computed as follows:

		For the six months ended June 30,
		2024				2025
Net income			60,750,732				66,776,511
Weighted average common shares – outstanding, basic			6,923,331				6,935,298
Basic earnings per share			8.77				9.63
Effect of dilutive securities:
Dilutive effect of unvested shares			50,642				23,100
Weighted average common shares – outstanding, diluted			6,973,973				6,958,398
Diluted earnings per share			8.71				9.60

For the six-month periods ended June 30, 2024 and 2025, the denominator of the diluted earnings per share calculation includes 50,642 and 23,100 common shares, respectively, being the number of incremental shares assumed issued under the treasury stock method.

12. Common shares and Additional paid-in capital

On May 23, 2022, the Company announced that its Board of Directors has approved a share repurchase program (“the Share Repurchase Program”) for up to a total of $20 million of the Company's common stock. The Board would review the program after a period of 12 months. This period was extended in each of May 2023, 2024 and 2025 for an additional period of 12 months. To date, about $10.5 million has been used to repurchase 466,374 shares of the Company. Share repurchases will be made from time to time for cash in open market transactions at prevailing market prices or in privately negotiated transactions. The timing and amount of purchases under the program will be determined by management based upon market conditions and other factors. The program does not require the Company to purchase any specific number or amount of shares and may be suspended or reinstated at any time at the Company's discretion and without notice.

During the six months ended June 30, 2024, the Company did not repurchase any shares in the open market under the Share Repurchase Program. During the six months ended June 30, 2025, the Company repurchased 40,925 common shares under the Share Repurchase Program in open market transactions for an aggregate consideration of approximately $1.3 million. The repurchased shares were cancelled and removed from the Company’s share capital.

The Company declared a cash dividend of $0.60 per common share in each of February and May 2024, totalling $8.4 million. The $8.31 million were paid within the six-month period and another $0.11 million were accrued, relating to dividends of unvested restricted shares. In the first six months of 2025, the Company declared a cash dividend of $0.65 per common share in each of February and June 2025, totalling $9.13 million. The $4.52 million were paid within the six-month period. As of June 30, 2025, $4.50 million of dividends were payable and subsequently settled in July 2025, and $0.24 million were accrued related to dividends on unvested restricted shares.

13. Financial Instruments

The principal financial assets of the Company consist of cash and cash equivalents, restricted cash, trade accounts receivable, other receivables and derivative. The principal financial liabilities of the Company consist of long-term debt, trade accounts payable, accrued expenses and amount due to related company.

Interest rate risk

The Company enters into interest rate swap contracts as economic hedges to manage some of its exposure to variability in its floating rate long-term debt. Under the terms of the interest rate swaps the Company and the bank agreed to exchange, at specified intervals the difference between a paying fixed rate and receiving floating rate interest amount calculated by reference to the agreed principal amounts and maturities. Interest rate swaps allow the Company to convert long-term debt issued at floating rates into equivalent fixed rates. Even though the interest rate swaps were entered into for economic hedging purposes, they do not qualify for hedge accounting, under the guidance relating to Derivatives and Hedging, as the Company does not have currently written contemporaneous documentation identifying the risk being hedged and, both on a prospective and retrospective basis, performing an effectiveness test to support that the hedging relationship is highly effective. Consequently, the Company recognizes the change in fair value of these derivatives in “Gain / (loss) on derivative, net” in the unaudited condensed consolidated statements of comprehensive income. As of June 30, 2025, the Company had one open swap contract for a notional amount of $20.0 million and hence, the Company is exposed to increases in interest rates on the remaining amount of its interest-bearing debt.

13. Financial Instruments - continued

Concentration of credit risk

Financial instruments, which potentially subject the Company to significant concentration of credit risk consist primarily of cash, trade accounts receivable and derivative. The Company places its temporary cash investments, consisting mostly of deposits, with high credit qualified financial institutions. The Company performs periodic evaluation of the relative credit standing of these financial institutions that are considered in the Company’s investment strategy. The Company limits its credit risk with trade accounts receivable by performing ongoing credit evaluations of its customers’ financial condition and generally does not require collateral for its trade accounts receivable as the Company in most cases gets paid in advance. The Company may be exposed to credit risk in the event of non-performance by its counterparties to derivative instruments; however, the Company limits its exposure by transacting with counterparties with high credit ratings.

Fair value of financial instruments

The Company follows guidance relating to “Fair value measurements”, which establishes a framework for measuring fair value under generally accepted accounting principles, and expands disclosure about fair value measurements.  This statement enables the reader of the financial statements to assess the inputs used to develop those measurements by establishing a hierarchy for ranking the quality and reliability of the information used to determine fair values. The statement requires that assets and liabilities carried at fair value will be classified and disclosed in one of the following three categories:

Level 1: Quoted market prices in active markets for identical assets or liabilities;

Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data;

Level 3: Unobservable inputs that are not corroborated by market data.

The estimated fair values of the Company's financial instruments such as cash and cash equivalents, restricted cash, trade accounts receivable, trade accounts payable and amount due to related company approximate their individual carrying amounts as of December 31, 2024 and June 30, 2025, due to their short-term maturity.  Cash and cash equivalents and restricted cash are considered Level 1 items as they represent liquid assets with short-term maturities. The fair value of the Company’s long-term debt, bearing interest at variable interest rates approximate their recorded values as of June 30, 2025, due to the variable interest rate nature thereof. SOFR rates are observable at commonly quoted intervals for the full terms of the financing arrangements and hence fair value of the long-term debt is considered Level 2 item in accordance with the fair value hierarchy due to their variable interest rate, being the SOFR.

The fair value of the Company’s interest rate swap agreement is determined using a discounted cash flow approach based on market-based SOFR swap rates. SOFR swap rates are observable at commonly quoted intervals for the full terms of the swap and therefore are considered Level 2 items. The fair value of the interest rate swap determined through Level 2 of the fair value hierarchy is derived principally from or corroborated by observable market data. Inputs include quoted prices for similar assets, liabilities (risk adjusted) and market-corroborated inputs, such as market comparables, interest rates, yield curves and other items that allow value to be determined.

14. Segment reporting

The Company reports financial information and evaluates its operations and operating results by total consolidated net income and not by the type of vessel, length of vessel employment, customer or type of charter. Although revenue can be identified for these types of charters or vessels, management cannot and does not identify expenses, profitability or other financial information for these various types of charters or vessels. As a result, the Company’s management, including its Chief Executive Officer, Mr. Aristides J. Pittas, who is the chief operating decision maker (“CODM”), does not use discrete financial information to evaluate the operating results for each such type of charter or vessel, but is instead regularly provided with only the consolidated expenses as noted on the face of the unaudited condensed consolidated statements of comprehensive income. The CODM assesses performance for the vessel operations segment and decides how to allocate resources based on consolidated net income. Net income is used to monitor budget versus actual results of the Company. The Company’s consolidated financial results are used in assessing the performance of the segment and in deciding whether to reinvest profits in the Company. As a result, management, including the CODM, reviews operating results solely by consolidated net income of the fleet, and thus the Company has determined that it operates under one operating and one reportable segment, that of operating container carriers. Furthermore, when the Company charters a vessel to a charterer, the charterer is free to trade the vessel worldwide and, as a result, the disclosure of geographical information is impracticable.

15. Subsequent Events
