Euroseas Ltd. Reports Results for the Year and Quarter Ended December 31, 2025

Maroussi, Athens, Greece – February 25, 2026 – Euroseas Ltd. (NASDAQ: ESEA, the “Company” or “Euroseas”), an owner and operator of container carrier vessels and provider of seaborne transportation for containerized cargoes, reported the following results for the three-month period and full year ended December 31, 2025.

Fourth Quarter 2025 Financial Highlights:

Total net revenues of $57.4 million. Net income of $40.5 million or $5.82 and $5.79 earnings per share basic and diluted, respectively. Adjusted net income¹ for the period was $31.3 million or $4.50 and $4.48 per share basic and diluted.

An average of 21.22 vessels were owned and operated during the fourth quarter of 2025 earning an average time charter equivalent rate of $30,268 per day.

Declared a quarterly dividend of $0.75 per share for the fourth quarter of 2025 payable on or about March 17, 2026 to shareholders of record on March 10, 2026 as part of the Company’s common stock dividend plan.

As of February 25, 2026, the Company has repurchased 480,455 of our common stock in the open market, representing about 6.8% of the outstanding shares, for a total of about $11.36 million, under the share repurchase plan of up to $20 million announced in May 2022.

Full Year 2025 Highlights:

Total net revenues of $227.9 million. Net income of $137.0 million or $19.73 and $19.72 earnings per share basic and diluted, respectively. Adjusted net income¹ for the period was $116.3 million or $16.75 and $16.74 per share basic and diluted, respectively.

Adjusted EBITDA¹was $155.9 million.

An average of 22.22 vessels were owned and operated during 2025, earning an average time charter equivalent rate of $29,107 per day.

Aristides Pittas, Chairman and CEO of Euroseas, commented: “We are pleased to report a very profitable fourth quarter with our earnings per share for the quarter being one of the highest ever. During the fourth quarter of 2025 and in January and February 2026 to date, containership charter rates maintain their high levels for one more time. Container freight rates were a bit more volatile, reflecting mostly seasonal trends. The strength of the charter market is evidenced by our most recent fixture for our M/V EM Spetses, a 19-year old, 1700 teu containership, that we announced recently.

“Our entire fleet is chartered at very profitable rates with our charter coverage for 2026 being about 87%, our coverage in 2027 exceeding 71% with many of our contracts extending well into 2028 and beyond. Our contracted revenues are over $550 million over the next five years and, even if we assume very conservative rates for our charter renewals, we expect to continue reporting strong profitability.

¹ Adjusted EBITDA, Adjusted net income and Adjusted earnings per share are not recognized measurements under U.S. GAAP (GAAP) and should not be used in isolation or as a substitute for Euroseas financial results presented in accordance with GAAP. Refer to a subsequent section of the Press Release for the definitions and reconciliation of these measurements to the most directly comparable financial measures calculated and presented in accordance with GAAP.

“Against this positive and quite protected situation for Euroseas, the overall containership market has to deal with a couple of challenges, mainly, the absorption of the high orderbook in the large containership segments and the eventual resumption of traffic through the Suez Canal which would reduce the demand for tonnage given the shorter distances required to travel. However, we would like to note that there is a stark difference between large containerships and the segments we operate, feeders and intermediate size vessels, as the latter not only face much lower orderbook levels but also have a large percentage of vessels over 20 years of age. Thus, we believe that it is very likely for the supply of feeders and intermediate containerships to contract, benefiting owners of modern vessels like us. Needless to say, the geo-political, economic and trade-related factors, like the renewed focus on US tariffs imposed, influence the volume of containerized trade and, consequently, demand for vessels, adding to the overall uncertainty in the markets.

“Nevertheless, given our strong balance sheet, we believe we are well positioned to take advantage of any developments in the markets, and we continuously evaluate and pursue accretive investment opportunities in both the secondhand and newbuilding sectors. At the same time, our balance sheet and contracted revenues backlog provide us with sufficient comfort to increase the rewards to our shareholders by increasing our dividend by 7% to $0.75 per share providing an annualized yield of about 5%.

Tasos Aslidis, Chief Financial Officer of Euroseas, commented: “Our net revenues for the fourth quarter of 2025 are increased by approximately 7.7% compared to the same period of 2024. This was the result of the increased average time charter rates our vessels earned in the fourth quarter of 2025, compared to the corresponding period of 2024. The Company operated an average of 21.22 vessels for the fourth quarter of 2025, versus 23.0 vessels during the same period last year. Net revenues amounted to $57.4 million for the fourth quarter of 2025 compared to $53.3 million for the fourth quarter of 2024.

“Total daily vessel operating expenses, including management fees, general and administrative expenses, but excluding drydocking costs, increased by approximately 7.2%, during the fourth quarter of 2025 compared to the same quarter of last year. This increase is mainly attributable to the increased cost of our stock incentive plan and increased U.S. dollar to euro exchange rate during the period.

“Adjusted EBITDA¹ during the fourth quarter of 2025 was $40.7 million compared to $32.8 million achieved in the fourth quarter of last year, reaching $155.9 million versus $135.8 million in the respective twelve-month periods of 2025 and 2024.

“As of December 31, 2025, our outstanding bank debt (excluding the unamortized loan fees) was $218.6 million, versus restricted and unrestricted cash of approximately $183.3 million. As of the same date, our scheduled debt repayments over the next 12 months amounted to about $19.5 million (excluding the unamortized loan fees).”

Fourth Quarter 2025 Results:

For the fourth quarter of 2025, the Company reported total net revenues of $57.4 million representing a 7.7% increase over total net revenues of $53.3 million during the fourth quarter of 2024, which was mainly the result of the higher time charter rates earned in the fourth quarter of 2025 compared to the corresponding period of 2024, partly offset by the decreased average number of vessels operating in the fourth quarter of 2025. The Company reported a net income for the period of $40.5 million, as compared to a net income of $24.4 million for the fourth quarter of 2024. On average, 21.22 vessels were owned and operated during the fourth quarter of 2025 earning an average time charter equivalent rate of $30,268 per day compared to 23.0 vessels in the same period of 2024 earning on average $26,479 per day.

For the fourth quarter of 2025, voyage expenses amounted to $0.1 million as compared to voyage expenses of $0.4 million for the same period of 2024. Voyage expenses for both periods related to owners’ expenses incurred in various ports.

Vessel operating expenses for the same period of 2025 amounted to $11.7 million as compared to $12.4 million for the same period of 2024. The decreased amount is mainly due to the lower number of vessels owned and operated in the last three months of 2025 compared to the same period of 2024.

Drydocking expenses amounted to $0.4 million during the fourth quarter of 2025 and relate to spare part supplies performed for upcoming drydocks. For the same period of 2024 drydocking expenses amounted to $2.5 million comprising the cost of one vessel passing its special survey with drydock and another one passing its intermediate survey in water.

Vessel depreciation for the fourth quarter of 2025 decreased to $6.8 million from $7.4 million in the fourth quarter of 2024, as a result of the decreased number of vessels in the Company’s fleet.

Related party management fees for the three months ended December 31, 2025 were $2.1 million compared to $1.8 million for the same period of 2024, as a result of the adjustment for inflation in the daily vessel management fee, effective from January 1, 2025, increasing it from 810 Euros to 840 Euros and the unfavorable movement of the euro/dollar exchange rate, partly offset by the lower average number of vessels owned and operated in the fourth quarter of 2025 compared to the same period of 2024.

The results of the Company for the fourth quarter of 2025 include a $9.2 million gain on sale of M/V “Marcos V” that was completed in October 2025.

General and administrative expenses increased to $2.4 million in the fourth quarter of 2025, as compared to $2.2 million in the fourth quarter of 2024, due mainly to the increased cost for our stock incentive plan.

Interest and other financing costs for the fourth quarter of 2025 amounted to $3.4 million, compared to $4.1 million, of which $0.6 million interest costs were capitalized in relation to our newbuilding program for the same period of 2024. This slight decrease is mainly due to the decreased benchmark interest rates of our bank loans in the current period, partly offset by the increased amount of debt in the current period compared to the same period of 2024.

For the three months ended December 31, 2025, the Company recognized a $0.02 million loss on its interest rate swap contract, comprising a $0.01 million unrealized loss from the mark-to-market valuation of our outstanding interest rate swap and a $0.01 million realized loss. For the three months ended December 31, 2024, the Company recognized a $0.5 million gain on its interest rate swap contract, comprising a $0.4 million unrealized gain from the mark-to-market valuation of our outstanding interest rate swap and a $0.1 million realized gain.

Adjusted EBITDA¹ for the fourth quarter of 2025 increased to $40.7 million compared to $32.8 million for the corresponding period in 2024.

Basic and diluted earnings per share for the fourth quarter of 2025 were $5.82 and $5.79 calculated on 6,957,348 and 6,991,738 basic and diluted weighted average number of shares outstanding, respectively, compared to basic and diluted earnings per share of $3.51 and $3.49, respectively, for the fourth quarter of 2024, calculated on 6,952,001 basic and 6,989,333 diluted weighted average number of shares outstanding.

The adjusted earnings for the quarter ended December 31, 2025, would have been $4.50 and $4.48 per share basic and diluted, respectively, compared to adjusted earnings of $3.35 and $3.33 per share basic and diluted, respectively, for the quarter ended December 31, 2024. Usually, security analysts include Adjusted Net Income in their determination of published estimates of earnings per share.

Full Year 2025 Results:

For the full year of 2025, the Company reported total net revenues of $227.9 million, representing a 7.0% increase, over total net revenues of $212.9 million during the twelve months of 2024, mainly as a result of the increased number of vessels owned and operated in the twelve months of 2025 compared to the corresponding period of 2024, and the higher average time charter equivalent rates earned in 2025. The Company reported a net income for the year of $137.0 million, as compared to a net income of $112.8 million for the twelve months of 2024. On average, 22.22 vessels were owned and operated during the twelve months of 2025 earning an average time charter equivalent rate of $29,107 per day compared to 21.73 vessels in the same period of 2024 earning on average $28,054 per day.

For the twelve months of 2025, voyage expenses amounted to $1.1 million, as compared to voyage expenses of $2.0 million in the same period of 2024. Voyage expenses for the twelve months of 2025 mainly related to owners expenses at certain ports, while for the corresponding period in 2024 related to expenses for vessels repositioning between charters and owners expenses at certain ports.

Vessel operating expenses for the twelve months of 2025 amounted to $46.8 million as compared to $46.7 million for the same period of 2024. This increase in vessel operating expenses is due to the higher average number of vessels operated by the Company in the twelve months of 2025 as compared to the same period of 2024, partly offset by the lower daily vessel operating expenses, mainly attributable to the significantly lower daily operating costs of the seven new building vessels delivered to the Company gradually within the past two years.

Drydocking expenses for the twelve months of 2025 amounted to $6.6 million (three of our vessels completed extensive repairs afloat and one of our vessels completed her special survey with drydock), compared to $10.5 million (five vessels passed their special survey with drydock, three vessels passed their intermediate survey in water) in the corresponding period of 2024.

Vessel depreciation for the twelve months of 2025 was $28.6 million compared to $26.4 million during the same period of 2024, due to the increased average number of vessels in the Company’s fleet.

Related party management fees for the twelve months of 2025 were $8.0 million compared to $7.1 million for the same period of 2024 as a result of the higher number of vessels in our fleet, the adjustment for inflation in the daily vessel management fee, effective from January 1, 2025, increasing it from 810 Euros to 840 Euros and the unfavorable movement of the euro/dollar exchange rate.

The results of the Company for the twelve months of 2025 include a $10.2 million gain on sale of M/V “Diamantis” that was completed in January 2025 and a $9.2 million gain on sale of M/V “Marcos V” that was completed in October 2025. The results of the Company for the twelve months of 2024 include a $5.7 million gain on sale of M/V “EM Astoria” that was completed in June 2024.

General and administrative expenses amounted to $6.8 million during the twelve months of 2025 as compared to $5.9 million in the last year. This increase is mainly attributable to the increased cost of our stock incentive plan and increased professional fees during 2025.

During the twelve months of 2025, we had other operating income of $0.12 million, relating to loss of hire insurance received for one of our vessels. No such case existed in 2024.

Total interest and other financing costs for the twelve months of 2025 amount to $15.1 million, of which $0.1 million interest costs were capitalized in relation to our newbuilding program, compared to $14.8 million, of which $4.2 million interest costs were capitalized in relation to our newbuilding program for the same period of 2024. This increase is mainly due to the increased amount of debt in the current period compared to the same period of 2024.

For the twelve months ended December 31, 2025, the Company recognized a $0.2 million loss on its interest rate swap contract, comprising a $0.4 million unrealized loss from the mark-to-market valuation of its outstanding interest rate swap and a $0.2 million realized gain. For the twelve months ended December 31, 2024, the Company recognized a $1.0 million gain on its interest rate swap contract, comprising a $0.6 million unrealized gain from the mark-to-market valuation of its outstanding interest rate swap and a $0.4 million realized gain.

Adjusted EBITDA¹ for the twelve months of 2025 increased to $155.9 million compared to $135.8 million during the twelve months of 2024, primarily as a result of higher revenues.

Basic and diluted earnings per share for the twelve months of 2025 were $19.73 and $19.72, calculated on 6,943,682 and 6,947,139 basic and diluted weighted average number of shares outstanding, respectively, compared to basic and diluted earnings per share of $16.25 and $16.20 for the twelve months of 2024, respectively, calculated on 6,938,204 basic and 6,961,266 diluted weighted average number of shares outstanding.

The adjusted earnings per share for the year ended December 31, 2025, would have been $16.75 and $16.74 basic and diluted, respectively, compared to adjusted earnings of $14.92 and $14.87 per share basic and diluted, respectively, for the year ended December 31, 2024. As mentioned above, security analysts include Adjusted Net Income in their determination of published estimates of earnings per share.

(1) Average number of vessels is the number of vessels that constituted the Company’s fleet for the relevant period, as measured by the sum of the number of calendar days each vessel was a part of the Company’s fleet during the period divided by the number of calendar days in that period.

(2) Calendar days. We define calendar days as the total number of days in a period during which each vessel in our fleet was in our possession including off-hire days associated with major repairs, drydockings or special or intermediate surveys or days of vessels in lay-up, or vessels that were committed for sale or suffered unrepaired damages. Calendar days are an indicator of the size of our fleet over a period and affect both the amount of revenues and the amount of expenses that we record during that period.

(3) The scheduled off-hire days including vessels laid-up, vessels committed for sale or vessels that suffered unrepaired damages, are days associated with scheduled repairs, drydockings or special or intermediate surveys or days of vessels in lay-up, or vessels that were committed for sale or suffered unrepaired damages.

(4) Available days. We define available days as the Calendar days in a period net of scheduled off-hire days as defined above. We use available days to measure the number of days in a period during which vessels were available to generate revenues.

(5) Commercial off-hire days. We define commercial off-hire days as days a vessel is idle without employment.

(6) Operational off-hire days. We define operational off-hire days as days associated with unscheduled repairs or other off-hire time related to the operation of the vessels.

(7) Voyage days. We define voyage days as the total number of days in a period during which each vessel in our fleet was in our possession net of commercial and operational off-hire days. We use voyage days to measure the number of days in a period during which vessels actually generate revenues or are sailing for repositioning purposes.

(8) Fleet utilization. We calculate fleet utilization by dividing the number of our voyage days during a period by the number of our available days during that period. We use fleet utilization to measure a company’s efficiency in finding suitable employment for its vessels and minimizing the amount of days that its vessels are off-hire for reasons such as unscheduled repairs or days waiting to find employment.

(9) Fleet utilization, commercial. We calculate commercial fleet utilization by dividing our available days net of commercial off-hire days during a period by our available days during that period.

(10) Fleet utilization, operational. We calculate operational fleet utilization by dividing our available days net of operational off-hire days during a period by our available days during that period.

(11) Average time charter equivalent rate, or average TCE, is a measure of the average daily net revenue performance of our vessels. Our method of calculating average TCE is determined by dividing time charter revenue and voyage charter revenue, if any, net of voyage expenses by voyage days for 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 or are paid by the Company under a voyage charter contract. Average TCE, which is a non-GAAP measure, provides additional meaningful information in conjunction with time charter revenue and voyage charter revenue (if any), the most directly comparable GAAP measure, because it assists our management in making decisions regarding the deployment and use of our vessels and because we believe that it provides useful information to investors regarding our financial performance. Average TCE is a standard shipping industry performance measure 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 and bareboat charters) under which the vessels may be employed between the periods. Our definition of average TCE may not be comparable to that used by other companies in the shipping industry.

(12) We calculate daily vessel operating expenses, which includes crew costs, provisions, deck and engine stores, lubricating oil, insurance, maintenance and repairs and related party management fees by dividing vessel operating expenses and related party management fees by fleet calendar days for the relevant time period. Drydocking expenses are reported separately.

(13) Daily general and administrative expenses are calculated by us by dividing general and administrative expenses by fleet calendar days for the relevant time period.

(14) Total vessel operating expenses, or TVOE, is a measure of our total expenses associated with operating our vessels. We compute TVOE as the sum of vessel operating expenses, related party management fees and general and administrative expenses; drydocking expenses are not included. Daily TVOE is calculated by dividing TVOE by fleet calendar days for the relevant time period.

(15) Daily drydocking expenses are calculated by us by dividing drydocking expenses by the fleet calendar days for the relevant period. Drydocking expenses include expenses during drydockings that would have been capitalized and amortized under the deferral method. Drydocking expenses could vary substantially from period to period depending on how many vessels underwent drydocking during the period. The Company expenses drydocking expenses as incurred.

Adjusted EBITDA Reconciliation:

Euroseas Ltd. considers Adjusted EBITDA to represent net income before interest and other financing costs, income taxes, vessel depreciation, impairment loss, (gain) / loss on interest rate swap derivative, net, gain on sale of vessels, and amortization of fair value of below market time charters acquired. Adjusted EBITDA does not represent and should not be considered as an alternative to net income, as determined by United States generally accepted accounting principles, or GAAP. Adjusted EBITDA is included herein because it is a basis upon which the Company assesses its financial performance and liquidity position and because the Company believes that this non-GAAP financial measure assists our management and investors by increasing the comparability of our performance from period to period by excluding the potentially disparate effects between periods of financial costs, (gain) / loss on interest rate swap, gain on sale of vessels, vessel depreciation and amortization of below market time charters acquired. The Company's definition of Adjusted EBITDA may not be the same as that used by other companies in the shipping or other industries.

Adjusted net income and Adjusted earnings per share Reconciliation:

Euroseas Ltd. considers Adjusted net income to represent net income before unrealized (gain) / loss on derivative, gain on sale of vessels, amortization of below market time charters acquired, impairment loss and vessel depreciation on the portion of the consideration of vessels acquired with attached time charters allocated to below market time charters. Adjusted net income and Adjusted earnings per share are included herein because we believe they assist our management and investors by increasing the comparability of the Company's fundamental performance from period to period by excluding the potentially disparate effects between periods of the aforementioned items, which may significantly affect results of operations between periods.

Adjusted net income and Adjusted earnings per share do not represent and should not be considered as an alternative to net income or earnings per share, as determined by GAAP. The Company's definition of Adjusted net income and Adjusted earnings per share may not be the same as that used by other companies in the shipping or other industries. Adjusted net income and Adjusted earnings per share are not adjusted for all noncash income and expense items that are reflected in our statement of cash flows.
