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)
Total charter days for fleet are the number of voyage days the vessels operated on time charters for the relevant period.
5)
Total spot market charter days for fleet are the number of voyage days the vessels operated on spot market charters for the relevant
period.
6)
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.

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

Notes to the unaudited interim condensed consolidated financial statements
(Expressed in United States dollars)



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. The reporting and functional currency of the Company is the United States Dollar.
The consolidated balance sheet as of December 31, 2024, has been derived from the audited consolidated financial statements at that
date, but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements.
At March 31, 2025, the Company’s fleet was comprised of 3 Handysize drybulk carriers and 1 Aframax crude oil tanker providing
worldwide marine transportation services under long, medium or short-term charters.
The Company’s vessels are managed by Brave Maritime Corporation S.A., a company controlled by members of the family of the
Company’s Non-Executive Director and former Parent Company’s Chief Executive Officer, since June 21, 2023. Brave Maritime Corporation
S.A. is incorporated in Liberia and registered in Greece under the provisions of law 89/1967, 378/1968 and article 25 of law 27/75 as amended
by article 4 of law 2234/94. Brave Maritime Corporation S.A. is herein referred to as the “Manager”.

On April 12, 2024, on December 31, 2024, and on April 3, 2025, the Company effected a 1-for-100, a 1-for-2.5 and a
1-for-6 reverse stock splits, of its shares of common stock (collectively referred to as “RSS”), respectively. All share and per share amounts
disclosed in these unaudited interim condensed consolidated financial statements give effect to the RSS, retroactively, for all periods
presented. The par value and other terms of the Company’s shares of common stock were not affected by the reverse stock split.

2.
Significant Accounting Policies
A discussion of the Company’s significant accounting policies can be found in the 2024 Consolidated Financial Statements. There have
been no material changes to these policies or pronouncements in the three months ended March 31, 2025.

3.
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.

On April 10, 2024, the Company entered into a memorandum of agreement with Transamerica Logistics Inc., a company affiliated with
members of the family of the Company’s Non-Executive Chairman for the acquisition of the vessel “Eco Spitfire” for an aggregate
consideration of $16,190,000. The vessel was delivered to the Company on May 10, 2024. 10% of the total consideration i.e. $1,619,000 was
paid in cash, while the remaining amount of $14,571,000 is payable in April 2025 and has no stated interest. The vessel was recorded at its
fair value of $15,000,000 as determined by an independent broker and the liability was recorded at $13,381,000 (the “Remaining purchase
price”) on May 10, 2024. 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.

Stockholders’ equity
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.

9.
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:
