Adjusted EBITDA for the first half of 2025 was $6.0 million, compared to $10.0 million for the same period of 2024. The TCE rate of the fleet for the first six months of 2025 was $12,744 per day compared to $16,187 in the same period of 2024. The average daily OPEX was $6,332 compared to $6,812 of the respective period of 2024.

Cash and cash-equivalents and restricted cash as of June 30, 2025, stood at $3.4 million. Shareholders’ equity at the end of the second quarter was $60.3 million, while long-term debt, finance lease liabilities and other financial liabilities, net of deferred finance costs stood at $83.8 million as of June 30, 2025. The book value of our fleet as of June 30, 2025, stood at $134.6 million, including one chartered-in Kamsarmax vessel and one Capesize vessel held for sale.

Stamatis Tsantanis, the Company’s Chairman & Chief Executive Officer, stated:

“In the second quarter of 2025 United Maritime achieved a daily TCE of $15,421, up 55% from Q1. This sharp recovery in our daily earnings confirms the strength of the dry bulk rebound and our ability to capture the upside.

“Our fleet modernization strategy continues with the divestment of older vessels, capitalizing on strong second-hand values. The sale of the 2004-built M/V Gloriuship was completed in June, and we recently agreed to sell the 2006-built M/V Tradership. These two sales have an aggregate net price of $32.8 million, which is expected to release approximately $17.9 million in liquidity after debt repayments. This strengthens our position to pursue new opportunities. We expect to deliver the M/V Tradership to its new owners within August and to record a book profit of approximately $1.5 million in the third quarter of 2025.

“Beyond our dry bulk operations, we have increased our equity stake in our newbuilding offshore ECV project to approximately 32%. This increase resulted in the full consolidation of the investment vehicle controlling 45% of the ECV, following which we recorded an accounting profit of $1.3 million. This strategic investment aligns with our objective to diversify into segments with strong market fundamentals, supported by ongoing investment in oil and gas infrastructure. Concerning the commercial prospects of this vessel, we are seeing healthy interest from charterers with more meaningful developments expected as we get closer to the delivery. The current market value of the vessel is estimated to be higher than the contract price, positioning us for a positive outcome regardless of the timing or structure of the chartering arrangements.

“Considering the positive momentum in the dry bulk market, the well-timed increase of our equity stake in the offshore project and the successful execution of our recent vessel sales, the board of directors has declared a $0.03 per share dividend, marking our 11th consecutive quarterly distribution — a clear signal of confidence in the outlook and our consistent return policy.

“Turning to our third quarter outlook, we have fixed approximately 68% of our available operating days at a daily rate of about $15,495. Based on the current FFA curve, we anticipate an overall Q3 TCE of approximately $14,707. This guidance reflects one Capesize and one Kamsarmax vessel earning fixed rates during the period. For the fourth quarter, 100% of our operating days remain open on index-linked rates.

“As regards the dry bulk market, both the Capesize and Panamax segments have rebounded sharply from the seasonal weakness of the first quarter. Panamax rates were driven by a surge in grain and coal cargoes after a period of slow demand, along with a reduction of vessel availability due to an increase in port days and congestion levels. In the Capesize market, the sharp rise in June iron ore exports significantly boosted spot rates, while Guinean bauxite exports remained robust throughout the first half of the year. On the supply side, the Capesize and Panamax orderbooks remain modest at approximately 8% and 14% of the existing fleet. Notably, around 7% and 16% of the respective fleets are over 20 years old. In the face of ever stricter environmental regulations effectively tightening vessel supply, this tight supply picture, combined with robust cargo flows, underpins our conviction that dry bulk markets are structurally positioned for strength into 2026. While dry bulk markets are always subject to high volatility, the resiliency displayed during a period of high macroeconomic uncertainty is very encouraging to see.

“United is executing on two fronts: generating strong near-term cash flows and unlocking long-term value through disciplined capital allocation across dry bulk and offshore sectors. At the same time, having declared about $1.65 per share in dividends since inception, our commitment to returning available capital to shareholders is well proven.”

Net Income / (Loss) to EBITDA and Adjusted EBITDA Reconciliation:

Earnings Before Interest, Taxes, Depreciation and Amortization (“EBITDA”) represents the sum of net income, net interest and finance costs, depreciation and amortization and, if any, income taxes during a period. EBITDA is not a recognized measurement under U.S. GAAP. Adjusted EBITDA represents EBITDA adjusted to exclude stock-based compensation, loss on extinguishment of debt, gain on consolidation and loss on equity method investment, which the Company believes are not indicative of the ongoing performance of its core operations.

EBITDA and Adjusted EBITDA are presented as we believe that these measures are useful to investors as a widely used means of evaluating operating profitability. EBITDA and Adjusted EBITDA as presented here may not be comparable to similarly titled measures presented by other companies. These non-GAAP measures should not be considered in isolation from, as a substitute for, or superior to financial measures prepared in accordance with U.S. GAAP.

Net Income / (Loss) and Adjusted Net Income / (Loss) Reconciliation and calculation of Adjusted Income / (Loss) Per Share

To derive Adjusted Net Income/ (Loss) and Adjusted Net Income / (Loss) Per Share, both non-GAAP measures, from Net loss, we exclude certain non-cash items, as provided in the table above. We believe that Adjusted Net Income/ (Loss) and Adjusted Net Income / (Loss) Per Share assist our management and investors by increasing the comparability of our performance from period to period since each such measure eliminates the effects of such non-cash items as stock-based compensation, loss on extinguishment of debt, gain on consolidation, loss on equity method investment and other items which may vary from year to year, for reasons unrelated to overall operating performance. In addition, we believe that the presentation of the respective measures provides investors with supplemental data relating to our results of operations, and therefore, with a more complete understanding of factors affecting our business than with GAAP measures alone. Our method of computing Adjusted Net Income / (Loss) and Adjusted Net Income / (Loss) Per Share may not necessarily be comparable to other similarly titled captions of other companies due to differences in methods of calculation.

Third Quarter 2025 TCE Rate Guidance:

As of the date hereof, approximately 68% of the Company fleet’s expected operating days in the third quarter of 2025 have been fixed at an estimated TCE rate of approximately $15,495. Assuming that for the remaining operating days of our index-linked T/Cs, the respective vessels’ TCE rate will be equal to Forward Freight Agreement (“FFA”) rate of $14,453 for Kamsarmax per day (based on the FFA curve of July 25, 2025), and considering that there are no remaining open days for our Capesize vessels during the quarter, our estimated TCE for the third quarter of 2025 is approximately $14,7072. Our TCE rate guidance for the third quarter of 2025 includes the already performed conversions of index-linked charters to fixed for the period.

The following table provides the breakdown of index-linked charters and fixed-rate charters in the third quarter of 2025:

Second Quarter and Recent Developments:

On July 10, 2025, the Company paid the previously announced quarterly dividend of $0.01 per common share, for the first quarter of 2025, to all shareholders of record as of June 30, 2025.

The Company also declared a cash dividend of $0.03 per common share for the second quarter of 2025 payable on or about October 10, 2025, to all shareholders of record as of August 18, 2025.

Sale of M/V Gloriuship

In June 2025, the Company delivered to her new owners the 171,314 dwt M/V Gloriuship, built in 2004. The aggregate net sale price was approximately $15.0 million.

Sale of M/V Tradership

In May 2025, the Company entered into a definitive agreement with an unaffiliated third party for the sale of a Capesize vessel, the 176,925 dwt M/V Tradership, built in 2006. The vessel is expected to be delivered to her new owners by mid-August 2025. The aggregate net sale price is approximately $17.8 million.

M/V Nisea – Time charter extension

In June 2025, the charterer of the M/V Nisea agreed to extend the time charter agreement in direct continuation from the previous agreement. The extension period commenced on July 21, 2025, for a duration of three months. The new gross daily hire is based at a premium over the Panamax Time Charter Average (“P5TC”), while all other main terms of the time charter remain materially unchanged.

2 This guidance is based on certain assumptions and the Company cannot provide assurance that these TCE rate estimates or projected utilization rates will be realized. TCE estimates include certain floating (index) to fixed rate conversions concluded in previous periods. For vessels on index-linked T/Cs, the TCE rate realized will vary with the underlying index, and for the purposes of this guidance, the TCE rate assumed for the remaining operating days of the quarter for an index-linked T/C is equal to FFA rate of $14,453 for Kamsarmax per day (based on the FFA curve of July 25, 2025). Spot estimates are provided using the load-to-discharge method of accounting. The rates quoted are for days currently contracted. Increased ballast days at the end of the quarter will reduce the additional revenues that can be booked based on the accounting cut-offs and therefore the resulting TCE rate will be reduced accordingly.

Offshore Sector

As previously announced, in April 2025 the Company increased its stake in a Norwegian-based company established to participate in the design and building of a technologically and environmentally advanced ECV. This expansion was facilitated through amendments to existing shareholders’ and subscription agreements. United had previously committed capital of up to $8.8 million, which was increased to approximately $10.4 million, representing an approximately 32% stake in the vessel.

The additional capital injection in the ECV project was financed by a $2.0 million short-term bridge loan facility provided by Seanergy Maritime Holdings Corp. which was fully repaid on June 17, 2025. The facility bore interest at a rate of 10.0% per annum.

Huarong Sale and Leaseback agreement

In June 2025, in connection to the sale of the M/V Gloriuship, the Company exercised its purchase option for the vessel under the Huarong Sale and Leaseback agreement, for a price of $7.6 million. All securities granted in favor of the M/V Gloriuship were irrevocably and unconditionally discharged pursuant to the deed of termination and release dated the same day.
