    CONDITION AND RESULTS OF OPERATIONS

    The following is a discussion of our financial condition and results of operations for the three-month period ended March 31, 2025 and the three-month period ended March 31, 2024. Unless otherwise specified herein, references to the “Company” or “we” shall include C3is Inc. and its subsidiaries. You should read the following discussion and analysis together with the unaudited interim condensed consolidated financial statements and related notes included elsewhere in this report. For additional information relating to our management’s discussion and analysis of financial condition and results of operations, please see our annual report on Form 20-F for the year ended December 31, 2024 filed with the U.S. Securities and Exchange Commission on April 28, 2025 (the “Annual Report”). This discussion contains forward-looking statements that reflect our current views with respect to future events and financial performance. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of certain factors, such as those set forth in the section entitled “Risk Factors” in our Annual Report. You should also carefully read the following discussion with “Forward-Looking Statements.”

    We use the term deadweight ton, or dwt, in describing the size of vessels. Dwt, expressed in metric tons, each of which is equivalent to 1,000 kilograms, refers to the maximum weight of cargo and supplies that a vessel can carry. Unless otherwise indicated, all references to “dollars” and “$” in this report are to, and amounts are presented in, U.S. dollars. All share amounts reflect the (1) 1-for-100 reverse split of the Common Stock effected by the Company at 11:59 pm, Eastern Time, on April 11, 2024, (2) 1-for-2.5 reverse split of the Common Stock effected by the Company at 11:59 pm, Eastern Time, on December 31, 2024; and (3) 1-for-6 reverse split of the Common Stock effected by the Company at 11:59 pm, Eastern Time, on April 3, 2025.

    Result of Operations

    Three-month period ended March 31, 2025 compared to three months ended March 31, 2024

    An average of 4.0 vessels were owned by the Company during the three months ended March 31, 2025, compared to 3.0 vessels for the same period in 2024.

     

      •  

    Voyage revenues for the three months ended March 31, 2025, amounted to $8.7 million, a decrease of $4.1 million compared to revenues of $12.8 million for the three months ended March 31, 2024, primarily due to the decrease in charter rates. Total calendar days for our fleet were 360 days for the three months ended March 31, 2025, as compared to 273 days for the same period in 2024. Of the total calendar days in the first three months of 2025, 247 or 68.6%, were time charter days, as compared to 164 or 60.1% for the same period in 2024. Our fleet utilization was 100.0% for both periods of the three months ended March 31, 2025 and 2024, and our fleet operational utilization was 91.7% and 93.4% for the three months ended March 31, 2025 and 2024, respectively.

     

      •  

    Voyage expenses and vessels’ operating expenses for the three months ended March 31, 2025, were $2.8 million and $2.2 million compared to $2.8 million and $1.8 million for the three months ended March 31, 2024. The increase in vessels’ operating expenses was attributed to the increase in the average number of our vessels. Voyage expenses for the three months ended March 31, 2025 included bunker cost and port expenses of $1.5 million and $0.9 million, respectively, corresponding to 54% and 32% of total voyage expenses, since the vessel Afrapearl II operated in the spot market. Operating expenses for the three months ended March 31, 2025 mainly included crew expenses of $1.1 million, corresponding to 50% of total operating expenses, spares and consumables costs of $0.4 million, corresponding to 18% of total vessel operating expenses, and maintenance expenses of $0.3 million, representing works and repairs on the vessels, corresponding to 14% of total vessel operating expenses.

    Table of Contents
      •  

    Depreciation for the three months ended March 31, 2025 was $1.6 million, a $0.2 million increase from $1.4 million for the same period of last year, due to the increase in the average number of our vessels.

     

      •  

    Management fees for the three months ended March 31, 2025 were $0.16 million, a $0.04 million increase from $0.12 million for the same period of last year, due to the increase in the average number of vessels.

     

      •  

    General and Administrative costs for the three months ended March 31, 2025 and 2024 were $0.7 million and $1.5 million, respectively. The decrease is mainly related to the decrease in equity offering expenses, which occurred in the three-month period ended March 31, 2024, while no offering expenses occurred in the first quarter of 2025. These offering expenses were allocated to warrants issued as part of the two public offerings and classified as liabilities.

     

      •  

    Interest and finance costs for the three months ended March 31, 2025 were $0.3 million and mainly related to the accrued interest expense – related party, in connection with the $14.6 million payable, representing 90% of the acquisition price of our bulk carrier, the Eco Spitfire; this balance was completely settled in April 2025. For the three months ended March 31, 2024, we reported $0.7 million as accrued interest expense – related party, in connection with $38.7 million payable, representing 90% of the acquisition price of our Aframax tanker, the Afrapearl II; this balance was completely settled in July 2024.

     

      •  

    Interest income for the three months ended March 31, 2025 and 2024 was $0.1 million and $0.2 million, respectively. The decrease is mainly attributed to a lower amount of funds placed under time deposits.

     

      •  

    Gain on warrants for the three months ended March 31, 2025 was $6.9 million and mainly related to the net fair value gains on our Class B-1, Class B-2, Class C-1 and Class C-2 warrants which were issued during the first quarter of 2024 in connection with the two public offerings and were classified as liabilities.

    Cash Flows

    Net cash provided by operating activities

    Net cash provided by operating activities was $3.3 million for the three months ended March 31, 2025 compared to $14.8 million for the same period in 2024. This decrease in operating cash flow of $11.5 million was mainly due to the decrease in our profitability by $4.3 million, excluding non-cash items, as well as a result of the unfavorable changes in assets and liabilities from working capital movements between the two periods such as trade and other receivables by $6.5 million due to less collections in 2025 as compared to 2024. Working capital is defined as current assets minus current liabilities.

    Net cash provided by investing activities

    Net cash provided by investing activities was $7.9 million for the three months ended March 31, 2025 due to the maturity of bank time deposits. Net cash provided by investing activities was $1.5 million for the three months ended March 31, 2024 due to the net increase of bank time deposits.

    Net cash provided by/ (used in) financing activities

    Net cash used in financing activities was $0.2 million for the three months ended March 31, 2025 representing dividends paid on the preferred stock. Net cash provided by financing activities for the three months ended March 31, 2024 was $11.2 million, representing proceeds from follow-on equity offerings and exercise of warrants, partially offset by the stock issuance costs and dividends paid on the preferred stock.

    Liquidity and Capital Resources

    As of March 31, 2025, we had cash and cash equivalents of $15.7 million.

    Our principal sources of funds for our liquidity needs have been cash flows from operations, as well as contribution from Imperial Petroleum Inc. (our former “Parent Company”), and three public offerings of equity securities. Potential additional sources of funds may include additional equity offerings and bank borrowings. We expect future equity offerings and other issuances of our common shares, preferred stock or other securities, which may dilute our common shareholders if issued at lower prices than the price they acquired their shares, as well as possibly bank borrowings, to be a significant component of the financing for our fleet growth plan. Our principal use of funds has been to acquire our vessels, maintain the quality of our vessels and fund working capital requirements.

    Our liquidity needs, as of March 31, 2025, primarily related to the funding of the remaining 90% of the purchase price of the acquired handysize bulk carrier, amounted to $14.57 million, which was paid off in full in April 2025. Our liquidity needs also include expenses for operating our vessels, any vessel improvements that may be required and general and administrative expenses.

    As of March 31, 2025, we had no bank debt. We may incur indebtedness in the future to finance the growth of our fleet.

    We believe that, unless there is a major and sustained downturn in market conditions applicable to our specific shipping industry segment and subject to either the successful completion of equity offerings or the incurrence of bank debts, our internally generated cash flows will be sufficient to fund our current operations, including working capital requirements, for at least 12 months as well as long-term, greater than 12 months, capital requirements, taking into account any possible capital commitments and debt service requirements.

    Forward-Looking Statements

    Matters discussed in this report may constitute forward-looking statements. Forward-looking statements reflect our current views with respect to future events and financial performance and may include statements concerning plans, objectives, goals, strategies, future events or performance, and underlying assumptions and other statements, which are other than statements of historical facts. The forward-looking statements in this report are based upon various assumptions, many of which are based, in turn, upon further assumptions, including without limitation, management’s examination of historical operating trends, data contained in our records and other data available from third parties. Although we believe that these assumptions were reasonable when made, because these assumptions are inherently subject to significant uncertainties and contingencies which are difficult or impossible to predict and are beyond our control, we assure you that it will achieve or accomplish these expectations, beliefs or projections. Important factors that, in our view, could cause actual results to differ materially from those discussed in the forward-looking statements include the strength of world economies and currencies, geopolitical conditions, including any trade disruptions resulting from tariffs and other protectionist measures imposed by the United States or other countries, general market conditions, including changes in charter hire rates and vessel values, supply and demand for drybulk cargoes, oil and oil products, charter counterparty performance, changes in demand that may affect attitudes of time charterers to scheduled and unscheduled drydockings, shipyard performance, changes in our operating expenses, including bunker prices, drydocking and insurance costs, ability to obtain financing and comply with covenants in our financing arrangements, our ability to comply with the Nasdaq listing rules, including maintaining compliance with the minimum bid price requirement, and remain listed on Nasdaq, potential liability from pending or future litigation or actions taken by regulatory authorities, domestic and international political conditions, the conflict in Ukraine and related sanctions, potential disruption of shipping routes due to accidents and political events, including the conflicts in the Middle East, Iran’s threat to close the Strait of Hormuz, and Houthi attacks in the Red Sea and the Gulf of Aden, or acts by terrorists. Risks and uncertainties are further described in the reports we file with the U.S. Securities and Exchange Commission.

      1.

    Basis of Presentation and General Information

    C3is Inc. (“C3is”) was formed by Imperial Petroleum Inc. (“the former Parent Company”) on July 25, 2022 under the laws of the Republic of the Marshall Islands. Initial share capital of C3is consisted of 500 common shares. Imperial Petroleum Inc. spun off its two Handysize drybulk carriers by contributing to C3is its interest in Drybulk International Trading and Shipping Inc. and in Raw Commodities & Exports Inc. (“Initial Fleet”), each one owning one Handysize drybulk carrier, and $5,000,000 in cash for working capital purposes. The contribution was completed on June 20, 2023 in exchange for 2,122 newly issued common shares and 600,000 5.00% Series A Perpetual Convertible Preferred Shares (the “Series A Preferred Shares”) in C3is. On June 21, 2023, Imperial Petroleum Inc., distributed the 2,122 common shares in C3is to the shareholders and warrant holders of Imperial Petroleum Inc. on a pro rata basis (the “Spin off”) and retained the 600,000 Series A Preferred Shares.

    The accompanying unaudited interim condensed consolidated financial statements include the accounts of C3is and its subsidiaries, (collectively, the “Company”). The Initial Fleet has been accounted using the historical carrying costs of its assets and liabilities from their dates of incorporation. The unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles or U.S GAAP, for interim financial information. Accordingly, they do not include all the information and notes required by U.S. GAAP for complete financial statements. These unaudited interim condensed consolidated financial statements have been prepared on the same basis and should be read in conjunction with the consolidated financial statements for the year ended December 31, 2024 included in the Company’s annual report on Form 20-F filed with the Securities and Exchange Commission on April 28, 2025 (the “2024 Consolidated Financial Statements”) and, in the opinion of management, reflect all adjustments which include only normal recurring adjustments considered necessary for a fair presentation of the Company’s financial position, results of operations and cash flows for the periods presented. Operating results for the three months ended March 31, 2025 are not necessarily indicative of the results that might be expected for the fiscal year ending December 31, 2025.

    Transactions with Related Parties

    The Manager provides the vessels with a wide range of shipping services such as chartering, technical support and maintenance, insurance, consulting, financial and accounting services, for a fixed daily fee of $440, as per the management agreement between the Manager and the Company.

    Based on the management agreement between the Manager and the Company, the Manager also receives a brokerage commission of 1.25% on freight, hire and demurrage per vessel. In addition, the Manager arranges for supervision onboard the vessels, when required, by superintendent engineers and when such visits exceed a period of five days in a twelve-month period, an amount of $500 is charged for each additional day (the “Superintendent fees”).

    The Manager also acts as a sales and purchase broker for the Company in exchange for a commission fee equal to 1% of the gross sale or purchase price of vessels or companies. The commission fees relating to vessels purchased (“Commissions – vessels purchased”) are capitalized to the cost of the vessels as incurred, and are included in “Vessels, net” in the unaudited interim condensed consolidated balance sheets.

    The Manager also provides crew management services to the vessels. These services have been subcontracted by the Manager to an affiliated ship-management company, Hellenic Manning Overseas Inc.. The Company pays to the Manager a fixed monthly fee of $2,500 per vessel for these services (the “Crew management fees”) and the related expense is included in “Operating expenses – related party” in the unaudited interim condensed consolidated statements of comprehensive income.

    In addition to management services, the Company reimburses the Manager for the compensation of its executive officers (the “Executive compensation”). Furthermore, the Company rents office space from the Manager and incurs a rental expense (the “Rental Expense”). The related expenses are included in “General and administrative expenses – related party” in the unaudited interim condensed consolidated statements of comprehensive income.

    The current account balance with the Manager at December 31, 2024 and March 31, 2025 was a liability of $1,441,251 and $2,413,771, respectively. The liability as at December 31, 2024 and as at March 31, 2025, mainly represents payments made by the Manager on behalf of the Company.

    On July 7, 2023, the Company entered into a memorandum of agreement with Imperial Petroleum Inc. for the acquisition of the vessel “Afrapearl II” for an aggregate consideration of $43,000,000. The vessel was delivered to the Company on July 14, 2023. 10% of the total consideration i.e. $4,300,000 was paid in cash, while the remaining amount of $38,700,000 was paid in July 2024 and had no stated interest. The vessel was recorded at its fair value of $40,000,000 as determined by an independent broker and the liability was recorded at $35,700,000 (the “Remaining Purchase Price”) on July 7, 2023. Since the payment of the remaining amount depended only on the passage of time, this arrangement was accounted for as seller financing and the financing component amounting to $3,000,000, being the difference between the Remaining Purchase Price and the amount of $38,700,000 that was paid in July 2024, was accounted for as interest over the life of the liability i.e. until July 2024. The interest expense amounting to $750,617 for the three month period ended March 31, 2024, is included in “Interest and finance costs – related party” in the unaudited interim condensed consolidated statement of comprehensive income.

Since the payment of the remaining amount of $14,571,000 depends only on the passage of time, this arrangement has been accounted for as seller financing and the financing component amounting to $1,190,000, being the difference between the Remaining purchase price and the amount of $14,571,000 payable in April 2025, will be accounted for as interest over the life of the liability i.e. until April 2025. The interest expense amounting to $328,582 for the three-month period ended March 31, 2025, is included in “Interest and finance costs – related party” in the unaudited interim condensed consolidated statement of comprehensive income.

    The current account balance with Imperial Petroleum Inc. at March 31, 2025 was a liability of $158,333 (December 31, 2024: $162,500). The liability for both periods related to the accrued dividend payable on Series A Preferred Shares.

    Fair Value of Financial Instruments and Concentration of Credit Risk

    Financial instruments, which potentially subject the Company to significant concentrations of credit risk, consist principally of cash and cash equivalents, time deposits, trade and other receivables, balances with related parties, trade accounts payable and accrued and other liabilities and warrant liability. The Company limits its credit risk with respect to accounts receivable by performing ongoing credit evaluations of its customers’ financial condition and generally does not require collateral for its trade accounts receivable.

    Fair Value Disclosures: The Company has categorized assets and liabilities recorded at fair value based upon the fair value hierarchy specified by the guidance. The levels of fair value hierarchy are as follows:

    Level 1: Quoted market prices in active markets for identical assets or liabilities.

    Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data.

    Level 3: Unobservable inputs that are not corroborated by market data.

    The carrying values of cash and cash equivalents, time deposits, balances with related parties, trade and other receivables, trade accounts payable and accrued and other liabilities are reasonable estimates of their fair value due to the short-term nature of these financial instruments. Cash and cash equivalents and time deposits are considered Level 1 items as they represent liquid assets with short-term maturities. The fair value of the Class B1, Class B2, Class C1 and Class C2 warrant liability is measured at each reporting period end and at each settlement date using the Black & Scholes model and is considered Level 3 item as it is derived by using significant unobservable inputs such as historical volatility.

    Details of the Company’s common stock and preferred stock are discussed in Note 8 of the 2024 Consolidated Financial Statements.

    Common stock and warrants:

    As of March 31, 2025, the exercise price and number of shares issuable upon exercise of the then outstanding Class B1, Class B2, Class C1 and Class C2 warrants was $1.3007, based on the lowest daily VWAP for the Company’s common stock during the adjustment period commencing five consecutive trading days immediately preceding and the five consecutive trading days following the reverse stock split effective on December 31, 2024 (Note 1). Following the reverse stock split effective on April 3, 2025 (Note 1), the exercise price of the Class B1, Class B2, Class C1 and Class C2 warrants was further adjusted to $3.0391, based on the lowest daily VWAP for the Company’s common stock during an adjustment period commencing five consecutive trading days immediately preceding and the five consecutive trading days following the reverse stock split effective on April 3, 2025, and the number of shares issuable upon exercise of the warrants were adjusted, as presented below, pursuant to the terms of the warrants, such that the aggregate exercise price of such warrants as of their original issuance date will remain unchanged.

    As of March 31, 2025, the Company re-valued the outstanding warrants classified as liabilities. For the three months ended March 31, 2025, the Company recognized a gain of $6,866,761 (2024: loss of $629,871) resulting from the change in the fair value of the liability for the unexercised warrants. The value of the outstanding warrants as of March 31, 2025, was $3,570,273 (December 31, 2024: $10,437,034) and presented under ‘Warrant liability” in the unaudited interim condensed consolidated balance sheets. The Company values its warrants classified as liabilities using Level 3 of the fair value hierarchy as defined in FASB guidance for Fair Value Measurements, as they are derived by using significant unobservable inputs such as historical volatility. The Company uses the Black & Scholes model for the valuation of the warrants at their issuance and at each settlement and measurement date, under the following assumptions (a) expected volatility (b) risk free rate (c) market value of common stock of, which was the current market price as of the date of each fair value measurement.

    For the valuation at March 31, 2025, the Company used a volatility of 60.96%, a risk free rate of 3.96% and a market value of common stock of $3.9.

    The following table presents the changes in the warrant liability during the period:

    Preferred shares:

    As of March 31, 2025, the conversion price of Series A Preferred shares was adjusted to $1.3007, after the RSS effective on December 31, 2024 (Note 1) and further adjusted to $3.0391, after the RSS effective on April 3, 2025 (Note 1). Pursuant to ASC 260, Earnings per Share, the Company recorded a deemed dividend for the down round adjustment of $462,000 which reduced income available to common shareholders in the Company’s earnings per share calculation (Note 9).

    Aggregate dividends of $0.2 million were paid on the Company’s Series A Preferred Shares during the three months ended March 31, 2025.

    Earnings per share

    All of the Company’s shares (including non-vested restricted stock issued under the Company’s equity compensation plans) participate equally in dividend distributions and in undistributed earnings. The Company applies the two-class method of computing earnings per share (“EPS”) as the unvested share-based payment awards that contain rights to receive non forfeitable dividends are participating securities. Dividends declared during the period for non-vested restricted stock as well as undistributed earnings allocated to non-vested stock are deducted from net income for the purpose of the computation of basic earnings per share in accordance with the two-class method. The denominator of the basic earnings per common share excludes any non-vested shares as such they are not considered outstanding until the time-based vesting restriction has elapsed. The denominator of the basic earnings per common share includes the total shares issuable upon the cashless exercise of the Class B1 and Class C1 warrants, as the exercise of the warrants is considered virtually certain taking into account that the holder of such warrants may elect to exercise them for no consideration. The Company calculates basic and diluted earnings per share as follows:

      •  

    The Company has met all of its capital expenditure commitments, totalling $59.2 million, without resorting to any bank loans. These expenditures mainly related to the acquisitions of our Aframax tanker, the Afrapearl II, and our bulk carrier, the Eco Spitfire.

     

      •  

    The Company recorded a non-cash adjustment of $6.4 million as “Loss on Warrants” for the three months ended June 30, 2025, mainly due to the change in the fair value of warrants between March 31, 2025 and June 30, 2025.

     

      •  

    In August 2025, our Aframax tanker, the Afrapearl II, successfully completed its dry-docking, over 23 days at a cost of approximately $1.3 million.

    Second Quarter 2025 Results:

     

      •  

    Voyage revenues for the three months ended June 30, 2025 amounted to $10.7 million, a decrease of $0.1 million compared to revenues of $10.8 million for the three months ended June 30, 2024, primarily due to the decrease in the average TCE rates of our vessels.

    CEO Dr. Diamantis Andriotis commented:

    For the first half of 2025, we reported Voyage Revenues of $19.4 million, EBITDA of $6.0 million, Net Income of $2.6 million, and EPS of $0.52.

    In April 2025 we paid off the remaining balance of $14.6 million due on our bulk carrier, the Eco Spitfire. In August 2025, we successfully completed the dry-docking of our Aframax tanker, the Afrapearl II.

    Major changes in the maritime shipping industry were caused by extensive transitions in the world due to geopolitical factors, environmental regulations, demand patterns and weather-related challenges. Despite these shifting dynamics, C3is Inc.’s performance remained solid, with an increase of its fleet capacity by over 230% since inception, without incurring any bank debt.

    We are fully deleveraged, thus significantly enhancing our financial flexibility. This financial position provides a strong foundation for our future growth.

    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 the 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.

    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.
