As of September 1, 2023, we had both of our Handysize drybulk carriers under time charter employment expiring in October 2023. All of our tanker vessels were operating in the spot market, as market conditions and rates were favorable for spot employment.

Fleet Developments

On June 21, 2023, we completed the spin-off of our previously wholly-owned subsidiary, C3is Inc., the holding company for two drybulk carriers, the Eco Angelbay and the Eco Bushfire, each with an aggregate capacity of 64,000 dwt. Imperial Petroleum stockholders and warrantholders received one C3is common share for every eight shares of Imperial Petroleum’s common stock owned, or in the case of holders of Imperial Petroleum’s outstanding Warrants that they have the right to purchase pursuant to Warrants owned, at the close of business on June 13, 2023. We retain an interest in C3is Inc. through our ownership of Series A Convertible Preferred Stock of C3is Inc., which has an aggregate liquidation preference of $15 million, a conversion price of $1.05 currently, and a dividend rate of 5.0% per annum.

In July 2023, we sold the M/T Stealth Berana, an Aframax oil tanker, built at Samsung shipyard, South Korea in 2010, with a cargo carrying capacity of 115,804 dwt, to C3is Inc., an affiliated company, for $43 million.

In September 2023, we entered into an agreement with entities affiliated with the family of our Chief Executive Officer to acquire two tanker vessels, the Aframax tanker Stealth Haralambos, built in 2009 and the product tanker Aquadisiac built in 2008, with an aggregate capacity of approximately 163,716 dwt. The aggregate purchase price for these acquisitions is $71 million. Both vessels will be delivered on a charter-free basis by the end of January 2024.

Result of Operations

Six-month period ended June 30, 2023 compared to the six-month period ended June 30, 2022

REVENUES- Total revenues for the six months ended June 30, 2023 amounted to $124.5 million, an increase of $108.0 million, or 654.5%, compared to revenues of $16.5 million for the six months ended June 30, 2022, primarily due to the increase in the average number of our vessels and improved market conditions resulting in higher rates particularly in the spot tanker market.

VOYAGE EXPENSES- Total voyage expenses for the six months ended June 30, 2023 were $36.1 million compared to $4.9 million for the six months ended June 30, 2022. The $31.2 million increase in voyage expenses is mainly due to the increase in the spot days of our fleet by 1,009 days (458.6%).

VESSELS’ OPERATING EXPENSES- Total vessels’ operating expenses for the six months ended June 30, 2023 were $13.9 million compared to $5.1 million for the six months ended June 30, 2022. The $8.8 million increase in vessels’ operating expenses was primarily due to the increase in the average number of our vessels in our fleet by approximately six vessels.

DRYDOCKING COSTS- Total drydocking costs for the six months ended June 30, 2023 and 2022 were $1.3 million and nil, respectively. This increase is due to the fact that during the six months ended June 30, 2023 two of our Handysize drybulk carriers underwent drydocking.

MANAGEMENT FEES – RELATED PARTY - Management fees were $0.9 million for the six months ended June 30, 2023 compared to $0.3 million for the six months ended June 30, 2022. The increase in management fees in the six months ended June 30, 2023 is attributed to the increase of our fleet by approximately six vessels.

GENERAL AND ADMINISTRATIVE EXPENSES — General and administrative expenses for the six months ended June 30, 2023 and 2022 were $2.5 million and $0.5 million, respectively. This rise of $2.0 million is mainly attributed to $1.1 million of stock-based compensation expense along with a rise in reporting costs related to our spin-off project.

DEPRECIATION — Depreciation for the six months ended June 30, 2023, was $8.7 million, a $3.8 million increase from $4.9 million for the same period of last year, due to the increase in the average number of our vessels.

INTEREST AND FINANCE COSTS — for the six months ended June 30, 2023 and 2022 were $1.8 million and $0.5 million, respectively. The $1.8 million of costs for the six months ended June 30, 2023 relates mainly to $1.3 million of interest charges incurred up to the full repayment of all outstanding loans concluded in April 2023 along with the full amortization of $0.5 million of loan related charges following the repayment of the Company’s outstanding debt. Interest and finance costs increased by $1.3 million during the six months ended June 30, 2023 compared to the six months ended June 30, 2022 mainly due to the increase in the average loan outstanding balance during the current period compared to the prior period. No debt was outstanding at June 30, 2023.

INTEREST INCOME- for the six months ended June 30, 2023 and 2022 was $2.1 million and $0.04 million, respectively. The increase is attributed to our time deposits during the period at favourable time deposit rates.

IMPAIRMENT LOSS- for the six months period ended June 30, 2023 stood at $9.0 million, and related to the spin-off of two of our four drybulk carriers to C3is Inc. The decline of drybulk vessels’ fair values compared to one year ago when these vessels were acquired resulted in the incurrence of impairment loss.

NET INCOME— As a result of the above, net income for the six months ended June 30, 2023 amounted to $52.6 million, compared to a net income of $0.3 million for the six months ended June 30, 2022.

5

Cash Flows

Net cash provided by operating activities — was $63.8 million for the six months ended June 30, 2023, compared to $1.3 million for the six months ended June 30, 2022. The increase in net cash provided by operating activities was mainly attributed to the increase in cash flows relating to the increased revenues partly offset by the increased cash outflows relating to our expenses as a result of the increase in average number of our vessels by approximately six vessels.

Net cash used in investing activities — was $20.2 million for the six months ended June 30, 2023. This amount mainly represents the aggregate consideration paid for the acquisition of two Handysize dry vessels offset by the net change of funds under time deposits. Net cash used in investing activities for the six months ended June 30, 2022 amounting to $79.0 million related to the acquisition of four tanker vessels.

Net cash provided by/(used in) financing activities — was an outflow of $64.4 million for the six months ended June 30, 2023, consisting mainly of $70.4 million utilized for loan repayments, $5.0 million of cash retained by C3is Inc. at its spin-off and $0.9 million paid for dividends on our Series A preferred shares partially offset by the $11.9 million of net proceeds from equity offerings. Net cash provided by financing activities for the six months ended June 30, 2022 amounted to $153.5 million and related mostly to $167.6 million raised from equity offerings partially offset by the $10.8 million of stock issuance costs and by the $2.4 million relating to loan repayments.

Liquidity and Capital Resources

As of June 30, 2023, we had cash and cash equivalents of $36.7 million and $61.9 million under time deposits. In August 2023, we completed an offering of 5,400,000 shares of common stock, 3,099,999 pre-funded warrants with an exercise price of $0.01 per share, of which 2,122,471 have subsequently been exercised, and 8,499,999 Class E Warrants with an exercise price of $2.00 per share, resulting in gross proceeds, before placement agent fees and transaction expenses, to us of approximately $17.0 million.

Our principal sources of funds for our liquidity needs have been equity offerings and cash flows from operations, which we expect to continue to be significant components of the financing for further fleet growth. Potential additional sources of funds include bank borrowings. Our principal use of funds has been to acquire our vessels, maintain the quality of our vessels, and fund working capital requirements. In July 2023, we sold our Aframax tanker to C3is Inc. for cash consideration of $43 million, of which $4.3 million was received by us upon delivery of the vessel on July 14, 2023 and the balance is payable to us by July 14, 2024.

Our liquidity needs, as of June 30, 2023, primarily relate to funding expenses for operating our vessels, any vessel acquisition and vessel improvements that may be required and general and administrative expenses. In August 2023, we entered into agreements to acquire two tankers for an aggregate purchase price of $71 million, which are scheduled to be delivered on a charter-free basis by the end of January 2024.

As of June 30, 2023, we had no outstanding debt, as within the first and second quarter of 2023 we repaid all our then outstanding loans amounting to $69.1 million.

We believe that our working capital along with our cash flows generated from operations are sufficient for our present short-term liquidity requirements. We believe that, unless there is a major and sustained downturn in market conditions applicable to our specific shipping industry segment, our internally generated cash flows will be sufficient to fund our operations, including working capital requirements, for at least 12 months taking into account any possible capital commitments and debt service requirements that may arise in the future.

In September 2023, the Company’s Board of Directors approved a share repurchase program and authorized the officers of the Company to repurchase, from time to time, up to $10,000,000 of the Company’s common stock.

Notes to the unaudited interim condensed consolidated financial statements

(Expressed in United States dollars)

1. General Information and Basis of Presentation

Imperial Petroleum Inc. (“Imperial”) was formed by StealthGas Inc (the “former Parent Company”) on May 14, 2021 under the laws of the Republic of the Marshall Islands. Initial share capital of Imperial consisted of 500 common shares. StealthGas Inc. separated its crude and product tankers by transferring to Imperial its interest in Clean Power Inc., MR Roi Inc., King of Hearts Inc. and Tankpunk Inc. (the “Subsidiaries”), each owning one tanker. The transfer was completed on November 10, 2021 in exchange for 4,774,772 newly issued common shares and 795,878 Series A 8.75% Preferred Shares (the “Series A Preferred Shares”) in Imperial. On December 3, 2021, StealthGas Inc. distributed the 4,775,272 common shares and 795,878 8.75% Series A Preferred Shares (with a liquidation preference of $25.00 per share) in Imperial to holders of StealthGas Inc.’s common stock on a pro rata basis (the “Spin-Off”). The accompanying unaudited interim consolidated financial statements include the accounts of Imperial and its wholly owned subsidiaries (collectively, the “Company”).

On June 21, 2023, the Company completed the spin-off transaction (the “Spin-off”) of its two Handysize drybulk carriers, “Eco Bushfire” and “Eco Angelbay” to its wholly-owned subsidiary C3is Inc. (“C3is”), which was formed by the Company in July 2022. Immediately prior to the Spin-off, Imperial received all issued and outstanding common shares and all 600,000 5.00% Series A Perpetual Convertible Preferred shares of C3is (Note 3) in exchange for the contribution of the entities owning the aforementioned vessels together with $5,000,000 in cash as working capital. Imperial, as the sole shareholder of C3is, distributed the C3is’s common shares to Company’s stockholders and warrant holders in accordance with the terms of the Company’s outstanding warrants on a pro rata basis on June 21, 2023. Common shares of C3is commenced trading on June 21, 2023 on the Nasdaq Capital Market under the ticker symbol “CISS”. C3is is a provider of international drybulk seaborne transportation services owning and operating the two Handysize drybulk carriers previously owned and operated by Imperial and is now a separate publicly traded company. Imperial Inc. continues to operate in the tanker and dry bulk shipping market and remains a publicly traded company.

2. Significant Accounting Policies

A discussion of the Company’s significant accounting policies can be found in the 2022 Consolidated Financial Statements. During the six-month period ended June 30, 2023, the Company adopted the following accounting policies:

New significant accounting policies adopted during the six months ended June 30, 2023

Investment in related party (Financial Instruments, Recognition and Measurement):

The Company has elected to measure equity securities without a readily determinable fair value, that do not qualify for the practical expedient in ASC 820 Fair Value Measurement to estimate fair value using the NAV per share (or its equivalent), at its cost minus impairment, if any. At each reporting period, the Company also evaluates indicators such as the investee’s performance and its ability to continue as going concern and market conditions, to determine whether an investment is impaired in which case, the Company will estimate the fair value of the investment to determine the amount of the impairment loss.

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 per vessel operating under a voyage or time charter or $125 per vessel operating under a bareboat charter (the “Management fees”) and a brokerage commission of 1.25% on freight, hire and demurrage per vessel (the “Brokerage commissions”), as per the management agreement between the Manager and the Company. 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 provides crew management services to the vessels Magic Wand, Clean Thrasher, Clean Sanctuary, Clean Justice, Suez Protopia, Suez Enchanted, Eco Wildfire, Glorieuse, Clean Nirvana since February 2023, Stealth Berana since April 2023, Eco Bushfire since September 2022 and up to the Spin-off and Eco Angelbay since October 2022 and up to the Spin-off. These services have been subcontracted by the Manager to an affiliated ship-management company, Hellenic Manning Overseas Inc. (ex. Navis Maritime Services Inc.). The Company pays to the Manager a fixed monthly fee of $2,500 per vessel for crew management services (the “Crew management 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.

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”).

On February 14, 2023, the Company entered into memoranda of agreement with companies affiliated with members of the family of the Company’s Chief Executive Officer for the acquisition of the vessels “Glorieuse” and “Eco Wildfire” for a total consideration of $35.5 million (Note 4). The vessels were delivered to the Company on March 27, 2023 and March 28, 2023, respectively. The aggregate purchase price of $18,500,000 of the vessel Glorieuse comprised of $8,500,000 in cash and 13,875 Series C Cumulative Convertible Perpetual Preferred Shares (“Series C Preferred Shares”) (Note 8).

On June 21, 2023, the Company completed the Spin-off (Note 1), and received 600,000 Series A Perpetual Convertible Preferred shares of C3is, having a liquidation preference of $25 per share and a par value of $0.01 per share. The Company is the holder of all of the issued and outstanding Series A Perpetual Convertible Preferred shares of C3is (Note 1). The Series A Perpetual Convertible Preferred shares do not have voting rights. The Series A Perpetual Convertible Preferred are convertible into common stock of C3is at the Company’s option at any time and from time to time on or after the date that is the date 90 days following the issuance date, at a conversion price equal to 150% of the VWAP of C3is common shares over the

F-8

five consecutive trading day period commencing on the issuance date. The conversion price will be adjusted to the lowest price of issuance of common stock by C3is in any registered offering of common stock of C3is after the original issuance of Series A Perpetual Convertible Preferred Shares. Furthermore, Imperial is entitled to receive cumulative cash dividends, at the annual rate of 5.00% on the stated amount of $25 per share, of the 600,000 Series A Perpetual Convertible Preferred shares, receivable quarterly in arrears on the 15th day of January, April, July and October in each year, subject to C3is’s Board of Directors approval. As the first cash dividend will be received on the 15th day of each October, the Company recognized for the period from June 21, 2023 to June 30, 2023, the amount of $20,833, which is presented in ‘Dividend income from related party’ in the accompanying unaudited interim condensed consolidated statements of comprehensive income.

As there was no observable market for the Series A Perpetual Convertible Preferred shares, these were recorded at $12,636,000 (Note 6), being the fair value of the shares determined through Level 2 inputs of the fair value hierarchy by taking into consideration a third-party valuation based on the income approach taking into account the present value of the future cash flows the Company expects to receive from holding the equity instrument.

As of June 30, 2023, the aggregate value of investments in C3is amounted to $12,656,833, including $20,833 of accrued dividends and are separately presented as ‘Investment in related party’ in the accompanying unaudited condensed consolidated balance sheet. As of June 30, 2023, the Company did not identify any indications for impairment or any observable prices for identical or similar investments of the same issuer.

The amounts charged by the Company’s related parties comprised the following:

On March 10, 2023, the Company prepaid $23.2 million representing the then outstanding balance of the term loan A using cash on hand and the related mortgage of the vessels “Magic Wand”, “Clean Thrasher”, “Clean Sanctuary” and “Stealth Berana” was released.

During the six-month period ended June 30, 2023, the Company repaid the amount of $1.4 million in line with the amortization schedule of the term loans B and C, and then proceeded with their full prepayment as follows:

On April 7, 2023, the Company prepaid $30.0 million representing the then outstanding balance of the term loan C using cash on hand and the related mortgage of the vessels “Suez Enchanted” and “Suez Protopia” was released.

On April 25, 2023, the Company prepaid $15.9 million representing the then outstanding balance of the term loan B using cash on hand and the related mortgage of the vessels “Clean Nirvana” and “Clean Justice” was released.

For the six-month periods ended June 30, 2023 and 2022 interest expense amounted to $1,271,409 and $362,365, respectively, and the weighted average interest rate of the Company’s term loans was 7.55% and 1.45%, respectively.

6. 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, trade accounts payable, balances with related parties and accrued liabilities. 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. The Company places its cash and cash equivalents, time deposits with high credit quality financial institutions. The Company performs periodic evaluations of the relative credit standing of those financial institutions.

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, trade and other receivables, trade accounts payable, balances with related parties other than investment in related party and accrued liabilities are reasonable estimates of their fair value due to the short term nature of these financial instruments. Cash and cash equivalents are considered Level 1 items as they represent liquid assets with short-term maturities. Investment in related party was initially measured at fair value which is deemed to be the cost and subsequently assessed for the existence of any observable market for the Series A Perpetual Convertible Preferred Shares and any observable price changes for identical or similar investments as well as the existence of any indications for impairment. As per the Company’s assessment no such case was identified as at June 30, 2023.

The valuation methodology applied comprised the bifurcation of the value of the Series A Perpetual Convertible Preferred shares in three components namely, the “straight” preferred stock component, the embedded option component and the control premium component. The mean of the sum of the three components was used to estimate the value for the Series A Perpetual Convertible Preferred shares at $12,636,000.

7. Stockholders’ Equity

Details of the Company’s common stock and preferred stock are discussed in Note 8 of the 2022 Consolidated Financial Statements and are supplemented by the below new activities in the six-month period ended June 30, 2023.

Common Shares:

i) NASDAQ Notification

On June 17, 2022, the Company received a written notification from the NASDAQ Stock Market, indicating that because the closing bid price of the Company’s common stock for 30 consecutive business days, from May 5, 2022 to June 16, 2022, was below the minimum $1.00 per share bid price requirement for continued listing on the Nasdaq Capital Market, the Company was not in compliance with Nasdaq Listing Rule 5550(a)(2). Pursuant to Nasdaq Listing Rule 5810(c)(3)(A), the applicable grace period to regain compliance was 180 days, or until December 14, 2022. In December 2022, the Company received formal notification from the Listing Qualification Department of the Nasdaq Stock Market notifying the Company that it has been granted an additional 180-day compliance period, or until June 12, 2023, to regain compliance with the minimum $1.00 bid price per share requirement of Nasdaq’s Marketplace Rule 5550(a)(2). At the opening of trading on April 28, 2023, following an approval from the Company’s Board of Directors, the Company effected 1-for-15 reverse stock split of the Company’s common stock. On May 16, 2023 the Company regained compliance with Nasdaq Listing Rule 5550(a)(2) concerning the minimum bid price of the Company’s common stock (Note 1).

ii) Equity Offerings

During the six-month period ended June 30, 2023, the Company completed a public offering of 3,287,062 shares of common stock resulting in gross proceeds of $12,095,253, or $11,896,666 in net proceeds.

iii) Warrants

As of June 30, 2023, none of remaining warrants were exercised. The number of remaining warrants was adjusted to reflect the 1-for-15 reverse stock split on April 28, 2023. As such, as of June 30, 2023, the number of common shares that can potentially be issued under each outstanding warrant are:

Warrant	Shares to be issued upon exercise of remaining warrants
Class A		2,867
Class B		786,800
Class C		5,218,591
Class D		2,076,667
Total		8,084,925

An aggregate of 291,194 additional common shares are potentially issuable upon exercise of the February 2022, March 2022 and May 2022 Representative Purchase Warrants.

Preferred Shares:

Aggregate dividends of $0.9 million were paid on the Company’s 795,878 Series A Preferred Shares during the six months ended June 30, 2023.

8. Mezzanine equity

On February 17, 2023, the Company entered into a Share Purchase Agreement with Flawless Management Inc. (Note 3) and sold to Flawless Management Inc. 13,875 newly issued Series C Cumulative Convertible Perpetual Preferred Shares (“Series C Preferred Shares”) having a liquidation preference of one thousand dollars ($1,000) per share (“the Liquidation Preference”). The Series C Cumulative Convertible Perpetual Preferred Shares were used as a partial consideration for the acquisition of the Handysize drybulk carrier “Glorieuse” (Note 4) from an affiliated company.

F-11

Each holder of Series C Preferred Shares, at any time and from time to time on or after the date that is the date immediately following the six-month anniversary of February 17, 2023, may elect to convert, in whole or in part, its Series C Preferred Shares into shares of common stock at a rate equal to the Series C Liquidation Preference, plus the amount of any accrued and unpaid dividend thereon to and including the conversion date, divided by the lower of (1) $7.50 and (2) the Ten-Day VWAP, subject to adjustment from time to time, provided, that, the conversion price shall not be less than $1.50. If the Company shall, at any time or from time to time, pay a stock dividend or otherwise makes a distribution or distributions on its shares of common stock or any other equity or equity equivalent securities payable in shares of common stock, or effect a subdivision or split of the outstanding common shares, the conversion price in effect immediately before such stock dividend or distribution, subdividision or split shall be proportionately decreased and, conversely, if the Company shall, at any time or from time to time, effect a combination (including by means of a reverse stock split) of the outstanding shares of common stock the conversion price in effect before such combination shall be proportionately increased. Following the reverse stock split on April 28, 2023 (Note 1), the conversion price was adjusted to reflect the 1-for-15 reverse stock split.

The holder of the Series C Preferred Shares shall be entitled to receive dividends from time to time out of any assets of the Company legally available for the payment of dividends at a rate equal to 5.00% per annum when, as, and if declared by the Board of Directors. Dividends, to the extent declared to be paid by the Company, shall be paid quarterly on each January 15, April 15, July 15 and October 15 of each year commencing on July 15, 2023. Dividends on the Series C Preferred Shares shall be payable based on a 360-day year consisting of twelve 30-day months. The dividend rate of 5.00% per annum is not subject to adjustment. As of June 30, 2023, the Company accrued dividend of $185,000 on the Company’s 13,875 Series C Preferred Shares that are payable to Flawless Management Inc. on July 15, 2023 (Note 3).

The Series C Preferred Shares are redeemable upon a change in control, which is defined as the acquisition by any “person” or “group” of beneficial ownership through a purchase, merger or other acquisition transaction or series of purchases, mergers or other acquisition transactions of the Company’s shares entitling that person or group to exercise more than 50% of the total voting power of all of the Company’s shares entitled to vote generally in elections of directors. The occurrence of the above events is not solely in the control of the Company, and hence Series C Preferred Shares has been classified in Mezzanine equity as per ASC 480-10-S99 “Distinguishing liabilities from Equity – SEC Materials”. The Series C Preferred Shares were recorded at $10.0 million at initial recognition representing the acquisition price of the vessel Glorieuse amounting to $18,5 million less the cash consideration of $8.5 million. The acquisition price of the vessel, which approximated its fair value as determined by an independent broker, was used for the determination of the fair value of the mezzanine equity, since it was more clearly evident and, thus, more reliably measurable than the fair value of the Series C Preferred Shares issued. The Company concluded that since the occurrence of the change in control events is not probable, it is not probable that the Series C Preferred Shares will become redeemable and no subsequent adjustment has been made in the amount presented in temporary equity in accordance with ASC 480-10-S99.

9. Equity Compensation Plan

Details of the Company’s equity compensation plan (the “Plan”) are discussed in Note 14 of the 2022 Consolidated Financial Statements and are supplemented by the below new transactions in the six-month period ended June 30, 2023.

On March 21, 2023, the Company granted $715,000 worth of shares of the Company’s common stock under the Plan to certain of the Company’s employees. The number of shares awarded was determined based on the closing price on the grant date i.e. March 21, 2023 which was equal to $2.55. 140,196 of the restricted shares vested on July 17, 2023 and the remaining 140,196 of the restricted shares will vest on July 17, 2024.

On May 15, 2023, the Company granted 547,550 restricted shares of common stock pursuant to the Plan to the Company’s CEO. The fair value of each share on the grant date was $3.48. 273,775 of the restricted shares will vest on May 15, 2024 and the remaining 273,775 of restricted shares will vest on May 15, 2025.

The related expense for shares granted to the Company’s CEO and certain of the Company’s employees for the six-month periods ended June 30, 2023 and 2022, amounted to $1,091,189 and $nil, respectively, and is included under general and administration expenses.

The unrecognized cost for the non-vested shares granted to the Company’s CEO and certain of the Company’s employees as of June 30, 2023 and December 31, 2022 amounted to $2,414,030 and $882,744, respectively. On June 30, 2023, the weighted-average period over which the total compensation cost related to non-vested awards granted to the Company’s CEO and certain of the Company’s employees not yet recognized is expected to be recognized is 2.37 years.

10. (Loss)/Earnings per share

The Company calculates basic and diluted loss/earnings per share as follows:

	For the six-month periods ended June 30,
	2022			2023
Numerator
Net income		304,101			52,550,587
Less: Cumulative dividends on Series A Preferred Shares		(870,492	)		(870,494	)
Less: Cumulative dividends on Series C Preferred Shares		—			(185,000	)
Less: Deemed dividend on warrant inducement		(2,943,675	)		—
Less: Undistributed earnings allocated to non-vested shares		—			(977,828	)
Net (loss)/ income attributable to common shareholders, basic		(3,510,066	)		50,517,265
Add: Undistributed earnings allocated to non-vested shares		—			977,828
Add: Cumulative dividends on Series C Preferred Shares		—			185,000
Less: Undistributed earnings re-allocated to non-vested shares		—			(862,466	)
Net (loss)/ income attributable to common shareholders, diluted		(3,510,066	)		50,817,627
Denominator
Weighted average number of shares outstanding, basic		4,359,423			15,940,369
Weighted average number of shares outstanding, diluted		4,359,423			18,113,785
(Loss)/ Earnings per share, basic		(0.81	)		3.17
(Loss)/Earnings per share, diluted		(0.81	)		2.81

As of June 30, 2023, diluted earnings per share reflects the potential dilution from conversion of outstanding Series C Preferred Shares (Note 8) calculated with the “if converted” method by using the average closing market price over the reporting period. Securities that could potentially dilute basic EPS in the future that were not included in the computation of diluted EPS, because to do so would have anti-dilutive effect, are any incremental shares of unexercised warrants, calculated with the treasury stock method. As of June 30, 2023, the aggregate number of unexercised warrants were 8,376,119 including Representative Purchase Warrants (Note 7).

As of June 30, 2022, securities that could potentially dilute basic EPS in the future that were not included in the computation of diluted EPS, because to do so would have anti-dilutive effect, are any incremental shares of unexercised warrants, calculated with the treasury stock method.

11. Revenues

The amounts in the accompanying unaudited condensed consolidated statements of comprehensive income are analyzed as follows:

	For the six-month periods ended June 30,

Other income		187,705		717,141
Total		16,464,649		124,465,322

As of December 31, 2022 and June 30, 2023, the Company recognized $240,002 and $376,132, respectively, of contract fulfillment costs which mainly represent bunker expenses incurred prior to commencement of loading relating to the Company’s voyage charters.

12. Commitments and Contingencies

• From time to time the Company expects to be subject to legal proceedings and claims in the ordinary course of its business, principally relating to personal injury and property casualty claims. Such claims, even if lacking merit, could result in the expenditure of significant financial and managerial resources. Currently, the Company is not aware of any such claims or contingent liabilities, which should be disclosed, or for which a provision should be established in the accompanying unaudited consolidated financial statements.

• Future minimum contractual charter revenues, gross of commissions, based on vessels committed to non-cancellable, time and bareboat charter contracts as of June 30, 2023, amount to $326,250 during the twelve months ending June 30, 2024.

13. Subsequent events

In July 2023, the Company concluded a memorandum of agreement for the disposal of the vessel “Stealth Berana” to C3is, an affiliated party, for $43,000,000. The vessel was delivered to her new owners in July 2023. The Company disposed the vessel “Stealth Berana” as the agreed selling price was a suitable opportunity for the Company.

In August 2023, the Company completed an underwritten public offering of 8,499,999 units, each unit consisting of (i) one share of common stock of the Company or one pre-funded warrant and (ii) one Class E Warrant to purchase one share of common stock at an exercise price of $2.00 per share.

General Information and Basis of Presentation

1. General Information and Basis of Presentation

Imperial Petroleum Inc. (“Imperial”) was formed by StealthGas Inc (the “former Parent Company”) on May 14, 2021 under the laws of the Republic of the Marshall Islands. Initial share capital of Imperial consisted of 500 common shares. StealthGas Inc. separated its crude and product tankers by transferring to Imperial its interest in Clean Power Inc., MR Roi Inc., King of Hearts Inc. and Tankpunk Inc. (the “Subsidiaries”), each owning one tanker. The transfer was completed on November 10, 2021 in exchange for 4,774,772 newly issued common shares and 795,878 Series A 8.75% Preferred Shares (the “Series A Preferred Shares”) in Imperial. On December 3, 2021, StealthGas Inc. distributed the 4,775,272 common shares and 795,878 8.75% Series A Preferred Shares (with a liquidation preference of $25.00 per share) in Imperial to holders of StealthGas Inc.’s common stock on a pro rata basis (the “Spin-Off”). The accompanying unaudited interim consolidated financial statements include the accounts of Imperial and its wholly owned subsidiaries (collectively, the “Company”).

On June 21, 2023, the Company completed the spin-off transaction (the “Spin-off”) of its two Handysize drybulk carriers, “Eco Bushfire” and “Eco Angelbay” to its wholly-owned subsidiary C3is Inc. (“C3is”), which was formed by the Company in July 2022. Immediately prior to the Spin-off, Imperial received all issued and outstanding common shares and all 600,000 5.00% Series A Perpetual Convertible Preferred shares of C3is (Note 3) in exchange for the contribution of the entities owning the aforementioned vessels together with $5,000,000 in cash as working capital. Imperial, as the sole shareholder of C3is, distributed the C3is’s common shares to Company’s stockholders and warrant holders in accordance with the terms of the Company’s outstanding warrants on a pro rata basis on June 21, 2023. Common shares of C3is commenced trading on June 21, 2023 on the Nasdaq Capital Market under the ticker symbol “CISS”. C3is is a provider of international drybulk seaborne transportation services owning and operating the two Handysize drybulk carriers previously owned and operated by Imperial and is now a separate publicly traded company.

New significant accounting policies adopted during the six months ended June 30, 2023

Investment in related party (Financial Instruments, Recognition and Measurement):

The Company has elected to measure equity securities without a readily determinable fair value, that do not qualify for the practical expedient in ASC 820 Fair Value Measurement to estimate fair value using the NAV per share (or its equivalent), at its cost minus impairment, if any. At each reporting period, the Company also evaluates indicators such as the investee’s performance and its ability to continue as going concern and market conditions, to determine whether an investment is impaired in which case, the Company will estimate the fair value of the investment to determine the amount of the impairment loss.

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 per vessel operating under a voyage or time charter or $125 per vessel operating under a bareboat charter (the “Management fees”) and a brokerage commission of 1.25% on freight, hire and demurrage per vessel (the “Brokerage commissions”), as per the management agreement between the Manager and the Company. 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 provides crew management services to the vessels Magic Wand, Clean Thrasher, Clean Sanctuary, Clean Justice, Suez Protopia, Suez Enchanted, Eco Wildfire, Glorieuse, Clean Nirvana since February 2023, Stealth Berana since April 2023, Eco Bushfire since September 2022 and up to the Spin-off and Eco Angelbay since October 2022 and up to the Spin-off. These services have been subcontracted by the Manager to an affiliated ship-management company, Hellenic Manning Overseas Inc. (ex. Navis Maritime Services Inc.). The Company pays to the Manager a fixed monthly fee of $2,500 per vessel for crew management services (the “Crew management 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.

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”).

On February 14, 2023, the Company entered into memoranda of agreement with companies affiliated with members of the family of the Company’s Chief Executive Officer for the acquisition of the vessels “Glorieuse” and “Eco Wildfire” for a total consideration of $35.5 million (Note 4). The vessels were delivered to the Company on March 27, 2023 and March 28, 2023, respectively. The aggregate purchase price of $18,500,000 of the vessel Glorieuse comprised of $8,500,000 in cash and 13,875 Series C Cumulative Convertible Perpetual Preferred Shares (“Series C Preferred Shares”) (Note 8).

On June 21, 2023, the Company completed the Spin-off (Note 1), and received 600,000 Series A Perpetual Convertible Preferred shares of C3is, having a liquidation preference of $25 per share and a par value of $0.01 per share. The Company is the holder of all of the issued and outstanding Series A Perpetual Convertible Preferred shares of C3is (Note 1). The Series A Perpetual Convertible Preferred shares do not have voting rights. The Series A Perpetual Convertible Preferred are convertible into common stock of C3is at the Company’s option at any time and from time to time on or after the date that is the date 90 days following the issuance date, at a conversion price equal to 150% of the VWAP of C3is common shares over the

five consecutive trading day period commencing on the issuance date. The conversion price will be adjusted to the lowest price of issuance of common stock by C3is in any registered offering of common stock of C3is after the original issuance of Series A Perpetual Convertible Preferred Shares. Furthermore, Imperial is entitled to receive cumulative cash dividends, at the annual rate of 5.00% on the stated amount of $25 per share, of the 600,000 Series A Perpetual Convertible Preferred shares, receivable quarterly in arrears on the 15th day of January, April, July and October in each year, subject to C3is’s Board of Directors approval. As the first cash dividend will be received on the 15th day of each October, the Company recognized for the period from June 21, 2023 to June 30, 2023, the amount of $20,833, which is presented in ‘Dividend income from related party’ in the accompanying unaudited interim condensed consolidated statements of comprehensive income.

As there was no observable market for the Series A Perpetual Convertible Preferred shares, these were recorded at $12,636,000 (Note 6), being the fair value of the shares determined through Level 2 inputs of the fair value hierarchy by taking into consideration a third-party valuation based on the income approach taking into account the present value of the future cash flows the Company expects to receive from holding the equity instrument.

As of June 30, 2023, the aggregate value of investments in C3is amounted to $12,656,833, including $20,833 of accrued dividends and are separately presented as ‘Investment in related party’ in the accompanying unaudited condensed consolidated balance sheet.

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments and Concentration of Credit Risk

6. 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, trade accounts payable, balances with related parties and accrued liabilities. 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. The Company places its cash and cash equivalents, time deposits with high credit quality financial institutions. The Company performs periodic evaluations of the relative credit standing of those financial institutions.

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, trade and other receivables, trade accounts payable, balances with related parties other than investment in related party and accrued liabilities are reasonable estimates of their fair value due to the short term nature of these financial instruments. Cash and cash equivalents are considered Level 1 items as they represent liquid assets with short-term maturities. Investment in related party was initially measured at fair value which is deemed to be the cost and subsequently assessed for the existence of any observable market for the Series A Perpetual Convertible Preferred Shares and any observable price changes for identical or similar investments as well as the existence of any indications for impairment. As per the Company’s assessment no such case was identified as at June 30, 2023.

	June 30, 2023		Significant other observable inputs (Level 2)		Total gain/ (loss)
Non-recurring fair value measurements
Investment in related party (Note 3)		12,636,000		12,636,000		—
Total investment in related party	$	12,636,000	$	12,636,000		—

The valuation methodology applied comprised the bifurcation of the value of the Series A Perpetual Convertible Preferred shares in three components namely, the “straight” preferred stock component, the embedded option component and the control premium component. The mean of the sum of the three components was used to estimate the value for the Series A Perpetual Convertible Preferred shares at $12,636,000. The valuation methodology and the significant other observable inputs used for each component are set out below:

	Valuation technique	Significant other observable input	Values
“Straight” Preferred Stock component	Discounted Cash Flow Model	- Weighted average cost of capital		13	%
Embedded Option component	Black & Scholes	- Volatility - Risk-free rate - Weighted average cost of capital - Strike price - Share price (based on the first 5 trading days volume weighted average)		78 4 13 $  3.50 $  2.33	%  %  %

(Note 3) and sold to Flawless Management Inc. 13,875 newly issued Series C Cumulative Convertible Perpetual Preferred Shares (“Series C Preferred Shares”) having a liquidation preference of one thousand dollars ($1,000) per share (“the Liquidation Preference”). The Series C Cumulative Convertible Perpetual Preferred Shares were used as a partial consideration for the acquisition of the Handysize drybulk carrier “Glorieuse” (Note 4) from an affiliated company.

Each holder of Series C Preferred Shares, at any time and from time to time on or after the date that is the date immediately following the six-month anniversary of February 17, 2023, may elect to convert, in whole or in part, its Series C Preferred Shares into shares of common stock at a rate equal to the Series C Liquidation Preference, plus the amount of any accrued and unpaid dividend thereon to and including the conversion date, divided by the lower of (1) $7.50 and (2) the Ten-Day VWAP, subject to adjustment from time to time, provided, that, the conversion price shall not be less than $1.50. If the Company shall, at any time or from time to time, pay a stock dividend or otherwise makes a distribution or distributions on its shares of common stock or any other equity or equity equivalent securities payable in shares of common stock, or effect a subdivision or split of the outstanding common shares, the conversion price in effect immediately before such stock dividend or distribution, subdividision or split shall be proportionately decreased and, conversely, if the Company shall, at any time or from time to time, effect a combination (including by means of a reverse stock split) of the outstanding shares of common stock the conversion price in effect before such combination shall be proportionately increased. Following the reverse stock split on April 28, 2023 (Note 1), the conversion price was adjusted to reflect the 1-for-15 reverse stock split.

The holder of the Series C Preferred Shares shall be entitled to receive dividends from time to time out of any assets of the Company legally available for the payment of dividends at a rate equal to 5.00% per annum when, as, and if declared by the Board of Directors. Dividends, to the extent declared to be paid by the Company, shall be paid quarterly on each January 15, April 15, July 15 and October 15 of each year commencing on July 15, 2023. Dividends on the Series C Preferred Shares shall be payable based on a 360-day year consisting of twelve 30-day months. The dividend rate of 5.00% per annum is not subject to adjustment. As of June 30, 2023, the Company accrued dividend of $185,000 on the Company’s 13,875 Series C Preferred Shares that are payable to Flawless Management Inc. on July 15, 2023 (Note 3).

The Series C Preferred Shares are redeemable upon a change in control, which is defined as the acquisition by any “person” or “group” of beneficial ownership through a purchase, merger or other acquisition transaction or series of purchases, mergers or other acquisition transactions of the Company’s shares entitling that person or group to exercise more than 50% of the total voting power of all of the Company’s shares entitled to vote generally in elections of directors. The occurrence of the above events is not solely in the control of the Company, and hence Series C Preferred Shares has been classified in Mezzanine equity as per ASC 480-10-S99 “Distinguishing liabilities from Equity – SEC Materials”. The Series C Preferred Shares were recorded at $10.0 million at initial recognition representing the acquisition price of the vessel Glorieuse amounting to $18,5 million less the cash consideration of $8.5 million. The acquisition price of the vessel, which approximated its fair value as determined by an independent broker, was used for the determination of the fair value of the mezzanine equity, since it was more clearly evident and, thus, more reliably measurable than the fair value of the Series C Preferred Shares issued. The Company concluded that since the occurrence of the change in control events is not probable, it is not probable that the Series C Preferred Shares will become redeemable and no subsequent adjustment has been made in the amount presented in temporary equity in accordance with ASC 480-10-S99.

On May 15, 2023, the Company granted 547,550 restricted shares of common stock pursuant to the Plan to the Company’s CEO. The fair value of each share on the grant date was $3.48. 273,775 of the restricted shares will vest on May 15, 2024 and the remaining 273,775 of restricted shares will vest on May 15, 2025.

(Loss)/ Earnings per share, basic		(0.81	)		3.17
(Loss)/Earnings per share, diluted		(0.81	)		2.81

As of June 30, 2023, diluted earnings per share reflects the potential dilution from conversion of outstanding Series C Preferred Shares (Note 8) calculated with the “if converted” method by using the average closing market price over the reporting period. Securities that could potentially dilute basic EPS in the future that were not included in the computation of diluted EPS, because to do so would have anti-dilutive effect, are any incremental shares of unexercised warrants, calculated with the treasury stock method. As of June 30, 2023, the aggregate number of unexercised warrants were 8,376,119 including Representative Purchase Warrants (Note 7).

As of June 30, 2022, securities that could potentially dilute basic EPS in the future that were not included in the computation of diluted EPS, because to do so would have anti-dilutive effect, are any incremental shares of unexercised warrants, calculated with the treasury stock method.

Investment in related party (Financial Instruments, Recognition and Measurement):

The Company has elected to measure equity securities without a readily determinable fair value, that do not qualify for the practical expedient in ASC 820 Fair Value Measurement to estimate fair value using the NAV per share (or its equivalent), at its cost minus impairment, if any. At each reporting period, the Company also evaluates indicators such as the investee’s performance and its ability to continue as going concern and market conditions, to determine whether an investment is impaired in which case, the Company will estimate the fair value of the investment to determine the amount of the impairment loss.
