1 Adjusted EBITDA, Adjusted net income and Adjusted earnings per share are not recognized measurements under US 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.

Aristides Pittas, Chairman and CEO of Euroseas, commented: “During the second quarter of 2025, the containership market continued its upward climb exceeding peak levels reached during 2024 in most cases. Although the number of charter transactions reported cooled off during July and early August, this was mostly due to lack of vessels rather than lack of interest. The strength of the market, especially for the feeder sector, was evidenced by long charter commitments by top quality charterers. Our vessels, all being fixed at highly profitable rates, have enabled us to produce one of our best quarterly results of the last five years in terms of adjusted earnings per share. Having charter coverage of almost 90% at similar rates over the next twelve months and assuming conservative rates for any re-charter renewals, we should be able to continue enjoying profitability at similar levels.

“As we have discussed in the past, the challenges the overall containership market faces are mainly centered around supply growth as the overall orderbook stands at almost 30% of the fleet. When the bulk of this orderbook is delivered in late 2026 and 2027 there could be rate pressures, in particular, if at the same time certain geopolitical issues -like the situation in the Red Sea- are resolved and, consequently, fewer ships are required to carry the containerized trade. On the flipside, the supply situation for feeder and intermediate segments, where we operate, is opposite to that of the overall fleet, i.e. fleet size will likely shrink, as these segments have still a low orderbook and a rather aged fleet profile, providing an advantage to owners like us. Trade wars and the uncertainty surrounding the new tariff regimes plus the still unfolding effect of the environmental regulations make the overall operating framework volatile in economic terms but, at the same time, potentially, very rewarding.

“We are committed to sail through the above environment by focusing on modernizing and upgrading our fleet as has been evidenced by our continuing newbuilding and retrofit programs while at the same time we look for accretive opportunities to invest in and, of course, continue to reward our shareholders. In that context, our Board has decided to increase our quarterly dividend by $0.05 to $0.70 per share maintaining an annualized yield in excess of 5.5% against our recent share price levels. We are also continuing to use our share buyback program, as our shares still trade at a substantial discount to our net asset value, despite the visibility of our revenues and earnings. As always, we remain committed to identifying attractive investment opportunities that enhance shareholder value and drive sustainable returns.”

Tasos Aslidis, Chief Financial Officer of Euroseas, commented: “Our revenues for the second quarter of 2025 are slightly lower compared to the same period of 2024. This was the result of the decreased time charter equivalent rate our vessels earned during the second quarter of 2025 compared to the same period of last year. On a per-vessel-per-day basis, our vessels earned a 7.0% lower average charter rate in the second quarter of 2025 as compared to the same period of 2024. Our net revenues decreased to $57.3 million in the second quarter of 2025 compared to $58.7 million during the same period of last year.

“Daily vessel operating expenses, including management fees but excluding drydocking costs, averaged $6,700 per vessel per day during the second quarter of 2025 as compared to $6,612 per vessel per day for the same quarter of last year. This was mainly the result of the falling value of the usd and the adjustment for inflation in the daily vessel management fee, effective from January 1, 2025, increasing it from 810 Euros to 840 Euros.

General and administrative expenses averaged $694 per vessel per day during the second quarter of 2025 as compared to $581 per vessel per day for the same quarter of last year, and $766 per vessel per day for the first half of 2025 as compared to $637 per vessel per day for the same period of 2024. The increase is due to increased professional fees and increased cost for our stock incentive plan within 2025 as compared to 2024.

“Adjusted EBITDA during the second quarter of 2025 was $39.3 million versus $42.3 million in the second quarter of last year. As of June 30, 2025, our outstanding debt (before deducting the unamortized loan fees) was $229.4 million versus restricted and unrestricted cash of $112.7 million. As of the same date, our scheduled bank debt repayments over the next 12 months amounted to about $21.2 million (before deducting the unamortized loan fees).”

Second Quarter 2025 Results:

For the second quarter of 2025, the Company reported total net revenues of $57.2 million representing a 2.5% decrease over total net revenues of $58.7 million during the second quarter of 2024. This was the result of the lower time charter rates our vessels earned in the second quarter of 2025 compared to the same period of 2024, partly offset by the increase in the average number of vessels owned and operated in the second quarter of 2025 compared to the same period of 2024. On average, 22.0 vessels were owned and operated during the second quarter of 2025 earning an average time charter equivalent rate of $29,420 per day compared to 21.26 vessels in the same period of 2024 earning on average $31,639 per day. The Company reported net income for the period of $29.9 million, as compared to net income of $40.7 million for the same period of 2024.

Voyage expenses, net for the second quarter of 2025 amounted to $0.3 million and relate to owners’ expenses incurred in various ports. For the same period of 2024, a gain on bunkers from the sale of M/V “EM Astoria”, resulted in positive voyage expenses of $0.3 million.

Vessel operating expenses were $11.5 million in the second quarter of 2025 as compared to $11.1 million for the second quarter of 2024. The increase is due to the higher average number of vessels owned and operated in the second quarter of 2025 compared to the corresponding period of 2024.

Depreciation expense for the second quarter of 2025 amounted to $7.3 million compared to $6.8 million for the same period of 2024 due to the increased number of vessels in the Company’s fleet.

Related party management fees for the second quarter of 2025 were also increased to $1.9 million from $1.7 million for the same period of 2024 due to the higher number of vessels in our fleet and the adjustment for inflation in the daily vessel management fee, effective from January 1, 2025, increasing it from 810 Euros to 840 Euros as well as due to the unfavorable movement of the euro/dollar exchange rate.

General and administrative expenses slightly increased to $1.4 million for the second quarter of 2025, compared to $1.1 million for the second quarter of 2024, due to increased professional fees and increased cost for our stock incentive plan.

In the second quarter of 2025 one of our vessels completed extensive repairs afloat. The total drydock cost for the quarter was $1.7 million and also includes costs in relation to the upcoming drydockings. In the second quarter of 2024 two of our vessels completed their special survey with drydock. The first one entered the drydock yard within the previous quarter and completed the survey in the second quarter while the second one was performed during the quarter. The total cost of these surveys was $1.6 million. The results of the Company for the second quarter of 2024 include a $5.7 million gain on sale of M/V “EM Astoria” that was completed in June 2024.

Total interest and other financing costs for the second quarter of 2025 amount to $4.0 million, compared to $2.1 million for the second quarter of 2024. Capitalized interest charged on the cost of our newbuilding program was $1.4 million for the second quarter of 2024 versus nil in the second quarter of 2025. This increase is due to the increased amount of debt in the current period compared to the same period of 2024.

For the three months ended June 30, 2025, the Company recognized a $0.05 million realized gain and a $0.11 million unrealized loss for a total of $0.06 million net loss on derivative. For the three months ended June 30, 2024, the Company recognized a $0.10 million realized gain and a $0.02 million unrealized gain for a total of $0.12 million net gain on derivative.

Adjusted EBITDA1 for the second quarter of 2025 was $39.3 million compared to $42.3 million achieved during the second quarter of 2024.

Basic and diluted earnings per share for the second quarter of 2025 was $4.32 and $4.29, calculated on 6,917,212 basic and 6,954,709 diluted weighted average number of shares outstanding, compared to basic and diluted earnings per share of $5.89 and $5.84, respectively, for the second quarter of 2024, calculated on 6,923,331 basic and 6,978,682 diluted weighted average number of shares outstanding.

The adjusted earnings per share for the quarter ended June 30, 2025 would have been $4.23 per share basic and $4.20 diluted, respectively, compared to adjusted earnings of $4.95 and $4.92 per share basic and diluted for the quarter ended June 30, 2024. Usually, security analysts include Adjusted Net Income in their determination of published estimates of earnings per share.

First Half 2025 Results:

For the first half of 2025, the Company reported total net revenues of $113.6 million representing a 7.7% increase over total net revenues of $105.4 million during the first half of 2024. On average, the Company owned and operated 22.83 vessels during the first half of 2025, earning an average time charter equivalent rate of $28,468 per day. For the same period of 2024 the Company owned and operated 20.43 vessels that earned on average $29,836 per day. The Company reported net income for the period of $66.8 million, as compared to net income of $60.8 million, for the first half of 2024.

Voyage expenses, net for the first half of 2025 amounted to $0.5 million as compared to voyage expenses, net of $0.8 million for the same period of 2024. The increased amount of 2024 is mainly attributable to 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”.

Vessel operating expenses for the first half of 2025 amounted to $23.7 million as compared to $22.5 million for the same period of 2024. The increase is due to the higher average number of vessels owned and operated in the first half of 2025 compared to the corresponding period of 2024 partly offset by the lower daily vessel operating expenses, mainly attributable to the significantly lower daily operating costs of the new building vessels delivered to the Company gradually within the last two years

Depreciation expense for the first half of 2025 was $15.3 million compared to $12.3 million during the same period of 2024, due to the increased number of vessels in the Company’s fleet.

Related party management fees for the first half of 2025 increased to $3.9 million from $3.3 million for the same period of 2024 as a result of the higher number of vessels in our fleet and the adjustment for inflation in the daily vessel management fee, effective from January 1, 2025, increasing it from 810 Euros to 840 Euros.

General and administrative expenses increased to $3.2 million for the first half of 2025, as compared to $2.4 million for the same period of 2024, due to increased professional fees and increased cost for our stock incentive plan.

In the first half of 2025 three of our vessels completed extensive repairs afloat for a total cost of approximately $3.5 million. In the same period of 2024 four of our vessels completed their special survey with drydock for a total cost of approximately $7.2 million.

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

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 $2.7 million for the same period of 2024. This increase is due to the increased amount of debt of our bank loans in the current period compared to the same period of 2024.

For the six months ended June 30, 2025 the Company recognized a $0.1 million realized gain and a $0.3 million unrealized loss for a total of $0.2 million net loss on derivative. For the six months ended June 30, 2024 the Company recognized a $0.2 million realized gain and a $0.8 million unrealized gain for a total of $1.0 million net gain on derivative.

Adjusted EBITDA1 for the first half of 2025 was $76.4 million compared to $66.9 million achieved during the first half of 2024.

Basic and diluted earnings per share for the first half of 2025 was $9.63 calculated on 6,935,298 basic and $9.60, calculated on 6,958,398 diluted weighted average number of shares outstanding, compared to basic and diluted earnings per share of $8.77 calculated on 6,923,331 basic and $8.71, calculated on 6,973,973 diluted weighted average number of shares outstanding, for the same period of 2024.

The adjusted earnings per share for the six-month period ended June 30, 2025 would have been $7.99 and $7.97, basic and diluted, respectively, compared to adjusted earnings per share of $7.63 basic and $7.57 diluted for the same period in 2024. As mentioned above, usually, 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. 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 number 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) Time charter equivalent rate, or TCE, is a measure of the average daily net revenue performance of our vessels. Our method of calculating 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. TCE, which is a non-GAAP measure, provides additional meaningful information in conjunction with voyage revenues, 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. 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 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. TVOE is 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 is 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, depreciation, (gain) / loss on interest rate swap derivative, net, gain on sale of vessel and amortization 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 supplemental basis upon which the Company assesses its financial performance 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 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 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 vessel, amortization of below market time charters acquired, 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 non-cash income and expense items that are reflected in our statement of cash flows.
