CEO Dr. Diamantis Andriotis commented:

We are very pleased to announce that, even though we have been operating as a newly listed entity for a short period of approximately 4 months following our spin-off from Imperial Petroleum Inc. in late June 2023, we have managed to grow our fleet and achieved a remarkable financial performance. Specifically, during the third quarter of 2023, we generated record revenues of $10.1 million and a record net income of $3.3 million, representing increases of 493% and 1,018% respectively, from the previous quarter.

Going forward, we strongly believe that the new acquisition of our Aframax oil tanker, which was delivered to us in July 2023, will well position us to capture the firm prevailing tanker market conditions and generate significant cash flow with the efficient operations of our expanded and diversified fleet. Specifically, our two handysize dry bulk carriers currently operate under short-term time charter contracts, earning gross charter rates ranging from $20,000 to $26,000 per day and resulting in a fixed revenue backlog of approximately $2.9 million until December 2023. Our already secured revenues are supplemented by the operation of our Aframax oil tanker in the spot market, where voyage charter rates for Aframax tankers currently stand at very high levels, in excess of $65,000 per day. This employment strategy will enhance our ability to finance our outstanding liability of $38.7 million, related to the acquisition of our tanker and due in July 2024, partially with cash on hand, cash from operating activities and proceeds from equity offerings.

With our Company’s impressive performance , we will continue to pursue growth strategies focused on timely and selective acquisitions of high-quality vessels which we may consider to be in the best interests of our Company and our shareholders.

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

2) Total calendar days for fleet are the total days the vessels we operated were in our possession for the relevant period including off-hire days associated with major repairs, drydockings or special or intermediate surveys.

3) Total voyage days for fleet reflect the total days the vessels we operated were in our possession for the relevant period net of off-hire days associated with major repairs, drydockings or special or intermediate surveys.

4) Fleet utilization is the percentage of time that our vessels were available for revenue generating voyage days, and is determined by dividing voyage days by fleet calendar days for the relevant period.

5) Total charter days for fleet are the number of voyage days the vessels operated on time or bareboat charters for the relevant period.

6) Total spot market charter days for fleet are the number of voyage days the vessels operated on spot market charters for the relevant period.

7) Fleet operational utilization is the percentage of time that our vessels generated revenue, and is determined by dividing voyage days excluding commercially idle days by fleet calendar days for the relevant period.

Reconciliation of EBITDA:

EBITDA represents net income before interest and finance costs, interest income and depreciation. EBITDA is not a recognized measurement under U.S. GAAP. Our calculation of EBITDA may not be comparable to that reported by other companies in the shipping or other industries.

EBITDA is included herein because it is a basis, upon which we and our investors assess our financial performance. It allows us to present our performance from period to period on a comparable basis and provides investors with a means of better evaluating and understanding our operating performance.

Reconciliation of TCE:

Time Charter Equivalent rate or “TCE” rate is determined by dividing voyage revenue net of voyage expenses by voyage days for the relevant time period. TCE is a non-GAAP measure which provides additional meaningful information in conjunction with voyage revenues, the most directly comparable GAAP measure to Time charter equivalent revenues assisting the Company’s management in making decisions regarding the deployment and use of its vessels and in evaluating their financial performance. TCE is also 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 charters or time charters, but not bareboat charters) under which the vessels may be employed between the periods.
