C3is Inc. reports second quarter and six months 2026 financial and operating results

ATHENS, Greece, Aug. 27, 2026 (GLOBE NEWSWIRE) — C3is Inc. (Nasdaq: CISS) (the “Company”), a ship-owning company providing drybulk, crude oil and petroleum products seaborne transportation services, announced today its unaudited financial and operating results for the second quarter and six months ended June 30, 2026.

OPERATIONAL AND FINANCIAL HIGHLIGHTS

• Our handysize dry bulk carriers are on time charters of short-term durations, producing steady cash flows, while our Aframax tanker operates in the spot market, currently achieving voyage charter rates of around $100,000 per day. Our product tankers are achieving rates of $30,000 per day on Spot.
• All our vessels are unencumbered.
• The Company had entered into agreements to acquire two product tankers for an aggregate consideration of $39.8 million, which amount is payable by January 2027. One of these tankers was delivered on April 3, 2026, while the second one was delivered on August 6, 2026. These acquisitions increase the Company’s exposure to the product tanker market.
• Fleet operational utilization of 78.6% for the three months ended June 30, 2026, mainly due to the commercial idle days of the Aframax tanker operating in the spot market and the off-hire days due to the dry-docking of the product tanker acquired during the period.

CEO Dr. Diamantis Andriotis commented:

Our results for the first six months of 2026 demonstrate the strength of our strategy and the significant progress we have achieved since the Company was established three years ago. Net Income totaled $13.18 million, up 409% compared with the first half of 2025, while Adjusted Net Income was $15.28 million, up 562%. EBITDA reached $16.6 million, up 176%, and Adjusted EBITDA stood at $18.7 million, up 226%.

These remarkable results validate our strategy of disciplined expansion and diversification. Since the beginning of the year, we have taken delivery of two product tankers, which are expected to further enhance and diversify our fleet profile while increasing our exposure to the tanker market, where charter rates currently remain at attractive levels.

We have also benefited from a flexible payment structure, under which the remaining acquisition costs of these recently acquired vessels are payable within one year from the respective acquisition agreements.

Most importantly, we have achieved this expansion while maintaining a debt-free fleet, providing a strong foundation for further growth and financial flexibility.

Looking ahead, we are confident that the second half of 2026 will mirror the strong performance of the first half, with our expansion efforts projected to further boost profitability, strengthen our financial position, and introduce greater flexibility for C3is’ future growth and operational strategy.

Fleet Data:
The following key indicators highlight the Company’s operating performance during the periods ended June 30, 2025, and June 30, 2026.

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 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 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 Adjusted Net Income, EBITDA, adjusted EBITDA and adjusted EPS:

Adjusted net income represents net (loss)/income before loss/(gain) on warrants and share based compensation. EBITDA represents net (loss)/income before interest and finance costs, interest income and depreciation. Adjusted EBITDA represents net (loss)/income before interest and finance costs, interest income, depreciation, loss/(gain) on warrants and share based compensation.

Adjusted EPS represents Adjusted net income divided by the weighted average number of shares. EBITDA, adjusted EBITDA, adjusted net income and adjusted EPS are not recognized measurements under U.S. GAAP. Our calculation of EBITDA, adjusted EBITDA, adjusted net income and adjusted EPS may not be comparable to that reported by other companies in shipping or other industries. In evaluating Adjusted EBITDA, Adjusted net income and Adjusted EPS, you should be aware that in the future we may incur expenses that are the same as or similar to some of the adjustments in this presentation.

EBITDA, adjusted EBITDA, adjusted net income and adjusted EPS are included herein because they are a basis, upon which we and our investors assess our financial performance. They allow us to present our performance from period to period on a comparable basis and provide investors with a means of better evaluating and understanding our operating performance. Management also uses these non-GAAP financial measures in making financial, operating and planning decisions and in evaluating our 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. TCE assists our investors to assess our financial performance from period to period on a comparable basis and provides investors with a means of better evaluating and understanding our operating performance.

ii The computation of (loss)/earnings per share gives retroactive effect to the reverse stock splits effected in April 2024, December 2024, April 2025, January 2026, April 2026 and August 2026.

¹ TCE, EBITDA, Adjusted EBITDA and Adjusted Net Income are non-GAAP measures. Refer to the reconciliation of these measures to the most directly comparable financial measure in accordance with GAAP set forth later in this release.
