Business Overview and Fleet Information

We are a growth-oriented global shipping company that was incorporated in the Republic of the Marshall Islands in September 2017 for the purpose of acquiring, owning, chartering and operating oceangoing cargo vessels. We are a provider of worldwide seaborne transportation services for dry bulk cargo as well as crude oil and refined petroleum products.

We currently operate a fleet of 23 vessels, consisting of 15 dry bulk carriers and 8 tankers with an aggregate cargo carrying capacity of 2.0 million dwt and an average age of 14.0 years (which we refer to throughout this report as our “Fleet”), and, as of the date of this report, we have agreed to acquire an additional 3 dry bulk vessels from unaffiliated sellers which we expect to take delivery of in the third quarter of 2021. Upon the successful consummation of our recent vessel acquisitions, our fleet will consist of 26 vessels, with an aggregate capacity of 2.2 million dwt, consisting of 1 Capesize, 7 Kamsarmax and 10 Panamax dry bulk vessels, as well as 1 Aframax, 5 Aframax/LR2 and 2 MR1 tankers.

We intend to continue to explore the market in order to identify potential acquisition targets which will help us grow our fleet and business. Our acquisition strategy has so far focused on secondhand Capesize, Kamsarmax, and Panamax dry bulk vessels as well as Aframax, Aframax/LR2 and MR1 tanker vessels, although we may acquire vessels in other sizes, age and/or sectors which we believe offer attractive investment opportunities.

Our commercial strategy primarily focuses on deploying our fleet under a mix of (a) period time charters and (b) trip time charters or voyage charters, according to our assessment of market conditions, adjusting the mix of these charters to take advantage of the stable cash flows and high utilization rates associated with period time charters or to profit from attractive spot charter rates during periods of strong freight market conditions.

Our vessels are technically managed by Pavimar S.A, or Pavimar, a company controlled by Ismini Panagiotidis, the sister of our Chairman, Chief Executive Officer and Chief Financial Officer, Petros Panagiotidis, and, commercially managed by Castor Ships S.A, or Castor Ships, a company controlled by our Chairman, Chief Executive Officer and Chief Financial Officer.

Operating results

Important Measures and Definitions for Analyzing Results of Operations

We believe that important concepts and measures for analyzing trends in our results of operations include the following:

Off-hire. The period our Fleet is unable to perform the services for which it is required under a charter for reasons such as scheduled repairs, vessel upgrades, dry-dockings or special or intermediate surveys or other unforeseen events.

Dry-docking/Special Surveys. We periodically dry-dock and/ or perform special surveys on our Fleet for inspection, repairs and maintenance and any modifications to comply with industry certification or governmental requirements. Our ability to control our dry-docking and special survey expenses and our ability to complete our scheduled dry-dockings and/or special surveys on time also affects our financial results. Dry-docking and special survey costs are accounted under the deferral method whereby the actual costs incurred are deferred and are amortized on a straight-line basis over the period through the date the next survey is scheduled to become due.

Time charter. A time charter is a contract for the use of a vessel for a specific period of time during which the charterer pays substantially all of the voyage expenses, including port charges, bunker expenses and canal charges. The vessel owner pays the vessel operating expenses, which include crew costs, provisions, deck and engine stores and spares, lubricants, insurance, maintenance and repairs. The vessel owner is also responsible for each vessel's dry-docking and intermediate and special survey costs. Time charter rates are usually fixed during the term of the charter. Prevailing time charter rates do fluctuate on a seasonal and year-to-year basis and may be substantially higher or lower from a prior time charter agreement when the subject vessel is seeking to renew the time charter agreement with the existing charterer or enter into a new time charter agreement with another charterer. Fluctuations in time charter rates are influenced by changes in spot charter rates.

Our results of operations are affected by numerous factors. Important factors that, in our view, have historically impacted our business and that are likely to continue to impact our business, are the following:

- The levels of demand and supply of seaborne cargoes and vessel tonnage in the dry bulk and tanker shipping industries;

- The cyclical nature of the shipping industry in general and its impact on charter rates and vessel values;

- Utilization rates of our Fleet;

- The employment and operation of our Fleet;

- Management of the financial, general and administrative elements involved in the conduct of our business and ownership of our Fleet;

- The performance of our charterers’ obligations under their charter agreements including our charterers ability to make charter payment to us;

- Our ability to maintain solid working relationships with our existing charterers and our ability to increase the number of our charterers through the development of new working relationships;

- The effective and efficient technical management of our Fleet by our Managers including the performance of their suppliers;

- The vetting approvals by oil majors of our commercial and technical managers for the management of our tanker vessels;

- Economic, regulatory, political and governmental conditions that affect shipping and the dry-bulk and tanker industries;

3

- Dry-docking and special survey costs and duration, both expected and unexpected;

- Our ability to successfully employ our vessels at economically attractive rates and our strategic decisions regarding the employment mix of our Fleet in the voyage, pool and time charter markets, as our charters expire or are otherwise terminated;

- Our ability to obtain equity and debt financing at acceptable and attractive terms to fund future capital expenditures;

- Our access to capital required to acquire additional ships and/or to implement our business strategy;

- The level of any distribution on all classes of our shares;

- Management of our financial resources, including banking relationships and of the relationships with our various stakeholders;

- Our borrowing levels and the finance costs related to our outstanding debt; and

- Major outbreaks of diseases (such as COVID-19) and governmental responses thereto.

Employment and operation of our Fleet

A factor that impacts our profitability is the employment and operation of our Fleet. The profitable employment of our Fleet is highly dependent on the levels of demand and supply in the dry bulk and tanker shipping industries, our commercial strategy including the decisions regarding the employment mix of our Fleet as well as our Managers’ ability to leverage our relationships with existing or potential customers. The effective operation of our Fleet mainly requires regular maintenance and repair, effective crew selection and training, ongoing supply of our Fleet with the spares and the stores that it requires, contingency response planning, auditing of our vessels’ onboard safety procedures, arrangements for our vessels’ insurance, chartering of the vessels, training of onboard and on shore personnel with respect to the vessels’ security and security response plans (ISPS), obtaining of ISM certifications and performing the necessary audit for the vessels within the six months of taking over a vessel and the ongoing performance monitoring of the vessels.

Financial, general and administrative management

The management of financial, general and administrative elements involved in the conduct of our business and ownership of our Fleet, requires us to manage our financial resources, including commercial and investment banking relationships; the efficient administration of bank accounts; manage the accounting system and records and financial reporting; monitor and ensure compliance with the legal and regulatory requirements affecting our business and assets; and manage our relationships with our service providers and customers.

Set forth below are selected operational and financial statistical data of our Fleet for each of the six month periods ended June 30, 2020 and 2021 that we believe are useful in better analyzing trends in our results of operations:

Results of Operations

Six months ended June 30, 2021 compared to the six months ended June 30, 2020

Vessel revenues

Vessel revenues, net of charterers’ commissions, increased from $5.3 million in the six months ended June 30, 2020, to $28.8 million in the same period of 2021. This increase was largely driven by the acquisition and delivery to our fleet of 20 vessels since June 30, 2021. The increase in vessel revenues during the six months ended June 30, 2021 as compared with the same period of 2020 was further underpinned by a stronger dry bulk shipping market resulting in higher daily net revenues earned on average for our fleet as compared with this earned during the same period of 2020.

Voyage expenses

Voyage expenses increased by $0.6 million, from $0.3 million in the six months ended June 30, 2020, to $0.9 million in the corresponding period of 2021. This increase in voyage expenses is mainly associated with an increase in brokerage commissions by $0.6 million, commensurate with the above discussed increase in vessel charter revenues.

Vessel operating expenses

The increase in operating expenses by $8.7 million, from $2.6 million in the six-month period ended June 30, 2020 to $11.3 million in same period of 2021 mainly reflect the increase in the number of vessels in our Fleet.

General and Administrative Expenses

General and administrative expenses in the six months ended June 30, 2020 amounted to $0.2 million, whereas, in the same period of 2021 general and administrative expenses totaled $1.5 million. This increase stemmed from incurred legal and other corporate fees primarily related to the growth of our company, and the $0.3 million quarterly flat fee we pay Castor Ships with effect from September 1, 2020.

6

Management fees- related party

Management fees in the six months ended June 30, 2020 amounted to $0.3 million, whereas, in the same period of 2021 management fees totaled $2.5 million. This increase in management fees is primarily due to the sizeable increase of our fleet following the acquisitions discussed above, resulting in a substantial increase in the total number of calendar days in the period during which we owned our vessels for which our managers charge us with a daily management fee. Effective September 1, 2020, the daily management fees for the technical management of our fleet by Pavimar, was increased from $500 to $600 per vessel and the daily management fees for the commercial and administrative management of our fleet by Castor Ships was set to $250 per vessel.

Depreciation and amortization

Depreciation and amortization expenses comprise of vessels’ depreciation and the amortization of vessels’ capitalized dry-dock costs. Depreciation and amortization charges totaled $0.7 million in the six months ended June 30, 2020, as compared to $4.0 million in the six months ended June 30, 2021.

Vessels’ depreciation increased from $0.7 million in the six-months ended June 30, 2020 to $3.7 million in the six-months ended June 30, 2021, reflecting primarily the increase in the size of our Fleet.

Interest and finance costs, net

The decrease by $0.8 million in net interest and finance costs in the six months ended June 30, 2021, as compared with the previous year’s six month period, is mainly the result of having incurred during the six months ended June 30, 2020, $1.1 million of non-cash recurring and accelerated amortization expenses related to deferred financing costs and to a beneficial conversion feature recognized in connection with our repaid, as of the same period, $5.0 million convertible debentures.

Significant Accounting Policies

There have been no material changes to our significant accounting policies since December 31, 2020. For a description of our significant accounting policies, see Note 2 to our audited consolidated financial statements included in our 2020 Annual Report, as supplemented by Note 2 to our interim unaudited consolidated financial statements contained elsewhere in this report.

Liquidity and Capital Resources

We operate in a capital-intensive industry and we expect to finance the purchase of additional vessels and other capital expenditures through a combination of proceeds from equity offerings, borrowings from debt transactions and cash generated from operations. Our liquidity requirements relate to servicing the principal and interest on our debt, funding capital expenditures and working capital (which includes maintaining the quality of our vessels and complying with international shipping standards and environmental laws and regulations) and maintaining cash reserves for the purpose of satisfying a certain minimum liquidity restrictions contained in our credit facilities. In accordance with our business strategy, other liquidity needs may relate to funding potential investments and maintaining cash reserves against fluctuations in operating cash flows. Our funding and treasury activities are intended to maximize investment returns while maintaining appropriate liquidity.

For the six months ended June 30, 2021, our principal sources of funds were the net proceeds from (i) the issuance of common stock pursuant to the three follow-on direct registered offerings we conducted in January and April of this year, (ii) the issuance of common stock pursuant to warrant exercises under our then effective warrant schemes, (iii) the incurrence of secured debt as discussed below under "Our Borrowing Activities", (iv) the issuance of common stock pursuant to sales under our current at-the-market common stock offering program and (v) cash flow from our operations. As of June 30, 2021 and December 31, 2020, we had cash and cash equivalents of $42.7 million and $9.4 million (which includes minimum cash restricted in both periods under our debt agreements). Cash and cash equivalents are primarily held in U.S. dollars.

As of June 30, 2021, we had $50.2 million of gross indebtedness outstanding under our debt agreements, of which $12.5 million matures in the twelve-month period ending June 30, 2022. As of June 30, 2021, we were in compliance with all the financial and liquidity covenants contained in our debt agreements.

Working capital is equal to current assets minus current liabilities. As of June 30, 2021, we had a working capital surplus of $30.6 million as compared to a working capital surplus of $2.7 million as of December 31, 2020. We believe that our current sources of funds and those that we anticipate to internally generate for a period of at least the next twelve months from the date of this report, will be sufficient to fund the operations of our Fleet, meet our normal working capital requirements and service the principal and interest on our debt.

On November 15, 2018, we entered into a contract to purchase and install ballast water management system (“BWMS”) on our dry bulk carriers, which was further amended on October 20, 2019 and December 8, 2020, to reflect our vessel acquisitions, as applicable in each period. We completed the BWMS installation on the Magic Sun during the vessel’s scheduled dry-docking which took place in the fourth quarter of 2020 and the BWTS was put into use during the second quarter of 2021. The BWMS system installations on the Magic P and the Magic Moon were granted extensions from the third quarter of 2020 to the third quarter of 2022. It is estimated that the contractual obligations related to these purchases as well as purchases on our remaining fleet vessels (where not already installed), excluding installation costs, will be on aggregate approximately €0.6 million (or $0.7 million on the basis of a Euro/US Dollar exchange rate of €1.0000/$1.1904 as of June 30, 2021), of which $0.01 million are due in 2021 and $0.69 million are due in 2022. These costs will be capitalized and depreciated over the remainder of the life of each vessel.

During the six months ended June 30, 2021, cash provided by operating activities in the amount of $7.2 million as compared to $0.4 million used in operating activities in the corresponding period of 2020, which represents an increase in cash provided from operating activities of $7.6 million. This increase is largely associated with expansion of our business and the higher net revenues we earned during the six month period ended June 30, 2021.

Our Borrowing Activities

Please refer to Notes 6 and 15 to our unaudited interim condensed consolidated financial statements, included elsewhere herein, for information regarding our borrowing activities as of June 30, 2021, and subsequent, as of the date of this report.

Cash Flows

The following table summarizes our net cash flows (used in)/provided from operating, investing and financing activities and our cash, cash equivalents and restricted cash for the six month periods ended June 30, 2020 and 2021:

	Six months ended June 30,
(in thousands of U.S. Dollars)	2020			2021
Net cash provided by / (used in) operating activities	$	(390,619	)	$	7,212,014
Net cash used in investing activities		(388,635	)		(255,124,019	)
Net cash provided by financing activities		26,974,956			281,168,137
Cash, cash equivalents and restricted cash at beginning of period		5,058,939			9,426,903
Cash, cash equivalents and restricted cash at end of period	$	31,254,641		$	42,683,035

Operating Activities: 

Net cash provided by operating activities amounted to $7.2 million for the six-month period ended June 30, 2021, consisting of net income after non-cash items of $11.7 million and a working capital cash decrease of $4.5 million.

Net cash used in operating activities amounted to $0.4 million for the six-month period ended June 30, 2020, consisting of net income after non-cash items of $1.1 million, offset by a reduction in working capital by $1.5 million.

The $7.6 million increase, hence, in net cash from operating activities in the six-month period ended June 30, 2021 as compared with the same period of 2020 reflects mainly the increase in net income after non-cash items.

Investing Activities: 

Net cash used in investing activities amounting to $255.1 million for the six-months ended June 30, 2021 mainly reflects the cash outflows associated with the vessel acquisitions we made during the period, as discussed in more detail under Note 5 of our unaudited interim consolidated financial statements included elsewhere in this report, and the costs paid for the BWMS purchases on the Magic P, Magic Sun and the Magic Vela.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Expressed in U.S. Dollars – except for share data unless otherwise stated)

1. Basis of Presentation and General information (continued):

The accompanying unaudited interim condensed consolidated financial statements include the accounts of Castor and its wholly owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) for interim financial information. Accordingly, they do not include all the information and notes required by U.S. GAAP for complete financial statements. These statements and the accompanying notes should be read in conjunction with the Company’s Annual Report on Form 20-F for the fiscal year ended December 31, 2020, filed with the SEC on March 30, 2021 (the “2020 Annual Report”).

These unaudited interim condensed consolidated financial statements have been prepared on the same basis as the annual 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 six-month period ended June 30, 2021 are not necessarily indicative of the results that might be expected for the fiscal year ending December 31, 2021.

2. Significant Accounting Policies and Recent Accounting Pronouncements:

A discussion of the Company's significant accounting policies can be found in the consolidated financial statements for the year ended December 31, 2020, included in the Company’s 2020 Annual Report. Apart from the below, there have been no material changes to these policies in the six-month period ended June 30, 2021.

New significant accounting policies adopted during the six months ended June 30, 2021

Segment Reporting

The Company reports financial information and evaluates its operations by charter revenues and not by the length, type of vessel or type of ship employment for its customers, i.e. time or voyage charters. The Company does not use discrete financial information to evaluate the operating results for each such type of charter or vessel. Although revenue can be identified for these types of charters or vessels, management cannot and does not identify expenses, profitability or other financial information for these various types of charters or vessels. As a result, management, including the chief operating decision maker, reviews operating results solely by revenue per day and operating results of the fleet, and thus the Company has determined that it operates as one reportable segment. Furthermore, when the Company charters a vessel to a charterer, the charterer is free to trade the vessel worldwide and, as a result, the disclosure of geographic information is impracticable.

Recent Accounting Pronouncements

There are no recent accounting pronouncements the adoption of which are expected to have a material effect on the Company’s unaudited interim consolidated condensed financial statements in the current period.

The Company accounted for the 2021 First, Second and Third Private Placement Warrants as equity in accordance with the accounting guidance under ASC 815-40. The accounting guidance provides a scope exception from classifying and measuring as a financial liability a contract that would otherwise meet the definition of a derivative if the contract is both (i) indexed to the entity's own stock and (ii) meets the equity classifications conditions. The Company concluded these warrants were equity-classified since they contained no provisions which would require the Company to account for the warrants as a derivative liability, and therefore were initially measured at fair value in permanent equity with subsequent changes in fair value not measured.

At-the-market (“ATM”) common stock offering program

On June 14, 2021, the Company, entered into an equity distribution agreement, or as commonly referred to, an at-the-market offering, with Maxim Group LLC (“Maxim”), under which the Company may sell an aggregate offering price of up to $300.0 million of its common stock with Maxim acting as a sales agent over a minimum period of 12 months (the “ATM Program”). No warrants, derivatives, or other share classes were associated with this transaction. As of June 30, 2021, the Company had received gross proceeds of $10.1 million under the ATM Program by issuing 3,563,407 common shares, whereas, the net proceeds under the ATM Program, after deducting sales commissions and other transaction fees and expenses, amounted to $9.7 million.

Issuance of common stock in connection with the Class A Warrants and the July 2020 equity offering warrants

During the six months ended June 30, 2021, the Company issued 5,546,705 common shares upon the exercise of an equivalent number of Class A Warrants issued in the June 2020 follow-on offering and 5,707,135 common shares upon the exercise of an equivalent number of warrants issued in the July 2020 follow-on equity offering. As of June 30, 2021, the Company raised $39.4 million in proceeds from the partial exercise of warrants issued in the respective equity offerings.

7. Equity Capital Structure (continued):

Reverse Stock Split

On May 28, 2021, the Company effected a 1-for-10 reverse stock split of its common stock without any change in the number of authorized common shares. All share and per share amounts, as well as warrant shares eligible for purchase under the Company's effective warrant schemes in the accompanying unaudited interim consolidated financial statements have been retroactively adjusted to reflect the reverse stock split. As a result of the reverse stock split, the number of outstanding shares as of May 28, 2021, was decreased to 89,955,848 while the par value of the Company's common shares remained unchanged to $0.001 per share.

8. Financial Instruments and Fair Value Disclosures:

The principal financial assets of the Company consist of cash at banks, restricted cash, trade accounts receivable and amounts due from related party. The principal financial liabilities of the Company consist of trade accounts payable, amounts due to related parties and long-term debt (including related party debt).

The following methods and assumptions were used to estimate the fair value of each class of financial instruments:

◾ Cash and cash equivalents, restricted cash, trade accounts receivable, amounts due from related party and trade accounts payable: The carrying values reported in the accompanying unaudited interim consolidated balance sheets for those financial instruments are reasonable estimates of their fair values due to their short-term maturity nature. Cash and cash equivalents and restricted cash, current are considered Level 1 items as they represent liquid assets with short term maturities. The carrying value approximates the fair market value for interest bearing cash classified as restricted cash, non-current and is considered Level 1 item of the fair value hierarchy. The carrying value of these instruments is separately reflected in the accompanying unaudited interim consolidated balance sheets.

◾ Long-term debt: The secured credit facilities discussed in Note 6, have a recorded value which is a reasonable estimate of their fair value due to their variable interest rate and are thus considered Level 2 items in accordance with the fair value hierarchy as LIBOR rates are observable at commonly quoted intervals for the full terms of the loans. The fair value of the fixed interest bearing $5.0 Million Term Loan Facility, discussed in Note 3, determined through Level 2 inputs of the fair value hierarchy (quoted prices for identical or similar assets and liabilities in markets that are not active), approximates its recorded value as of June 30, 2021.

Concentration of credit risk: Financial instruments, which potentially subject the Company to significant concentrations of credit risk, consist principally of cash and cash equivalents and trade accounts receivable. The Company places its cash and cash equivalents, consisting mostly of deposits, with high credit qualified financial institutions. The Company performs periodic evaluations of the relative credit standing of the financial institutions in which it places its deposits. The Company limits its credit risk with accounts receivable by performing ongoing credit evaluations of its customers' financial condition.

9. Commitments and contingencies:

Various claims, lawsuits, and complaints, including those involving government regulations and product liability, arise in the ordinary course of the shipping business. In addition, losses may arise from disputes with charterers, agents, insurance and other claims with suppliers relating to the operations of the Company's vessels. Currently, management 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 interim consolidated financial statements.

9. Commitments and contingencies (continued):

The Company accrues for the cost of environmental liabilities when management becomes aware that a liability is probable and is able to reasonably estimate the probable exposure. Currently, management 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 interim consolidated financial statements. The Company is covered for liabilities associated with the vessels’ actions to the maximum limits as provided by Protection and Indemnity (P&I) Clubs, members of the International Group of P&I Clubs.

(a) Commitments under Contracts for BWMS Installation

On November 15, 2018, the Company entered into a contract to purchase and install BWMS on its dry bulk carriers, which was further amended on October 20, 2019 and December 8, 2020, to reflect the Company’s vessel acquisitions, as applicable in each period. The Company completed the BWMS installation on the Magic Sun during the vessel’s scheduled dry-docking which took place in the fourth quarter of 2020 and the BWMS was put into use during the second quarter of 2021. The BWMS system installations on the Magic P and the Magic Moon were granted extensions from the third quarter of 2020 to the third quarter of 2022. It is estimated that the contractual obligations related to these purchases as well as purchases on the Company’s remaining fleet vessels (where not already installed), excluding installation costs, will be approximately €0.6 million (or $0.7 million on the basis of a Euro/US Dollar exchange rate of €1.0000/$1.1904 as of June 30, 2021), of which $0.01 million are due in 2021 and $0.69 million are due in 2022. These costs will be capitalized and depreciated over the remainder of the life of each vessel.

(b) Commitments under long-term lease contracts

The following table sets forth the Company’s future minimum contracted lease payments (gross of charterers’ commissions), based on vessels’ commitments to non-cancelable fixed time charter contracts as of June 30, 2021. The calculation does not include any assumed off-hire days.

Twelve-month period ending June 30,	Amount
2022	$	25,815,300
Total	$	25,815,300

10. Earnings/ (Loss) Per Share:

The Company calculates earnings/(loss) per share by dividing net income/(loss) available to common stockholders in each period by the weighted-average number of common shares outstanding during that period, after adjusting for the effect of cumulative dividends on the Series A Preferred Shares, whether or not earned, and only at periods when dividends on the Series A Preferred Shares are contractually allowed to accumulate. As further disclosed under Note 7 of the audited financial statements included in the 2020 Annual Report, dividends on the Series A Preferred Shares neither accrue nor accumulate during the period from July 1, 2019 until December 31, 2021 and the Company does not have any dividend priority restrictions to holders of its common shares during this period.

Diluted earnings/(loss) per share, if applicable, reflects the potential dilution that could occur if potentially dilutive instruments were exercised, resulting in the issuance of additional shares that would then share in the Company’s net income. During the six months ended June 30, 2021, the denominator of diluted earnings per common share calculation includes the incremental shares assumed issued under the treasury stock method weighted for the period the shares were outstanding with respect to warrants outstanding as of June 30, 2021. During the six months ended June 30, 2020, securities that could potentially dilute basic loss per share that were excluded from the computation of diluted loss per share, because to do so would have been antidilutive for the period presented, were the incremental shares in connection with the unexercised, as of June 30, 2020, Class A warrants, calculated in accordance with the treasury stock method.

11. Vessel Revenues:

The following table includes the voyage revenues earned by the Company from time charters, voyage charters and pool agreements for the six month periods ended June 30, 2020 and 2021, as presented in the accompanying unaudited interim condensed consolidated statements of comprehensive income/(loss):

	Six months ended June 30,		Six months ended June 30,
	2020		2021
Time charter revenues		5,310,936		27,635,487
Voyage charter revenues		—		693,471
Pool revenues		—		433,678
Total Vessel revenues	$	5,310,936	$	28,762,636

As of June 30, 2021, trade accounts receivable, net increased by $1,496,824 and deferred revenue increased by $1,564,978 compared to December 31, 2020. These changes were mainly attributable to the timing of collections and the timing of commencement of revenue recognition, the increase in charter rates and the increase in vessel revenues resultant to the growth of the Company’s fleet during the six months ended June 30, 2021. As of June 30, 2021, the Company had no deferred revenue related to undelivered performance obligations under any of its voyages in progress.

Further, as of June 30, 2021, deferred assets related to revenue contracts presented under “Deferred charges, net” amounted to $142,898 compared to $0 as of December 31, 2020 and will be expensed during the third quarter of 2021. This change was mainly attributable to the timing of commencement of revenue recognition.

Management Commentary:

Mr. Petros Panagiotidis, Chief Executive Officer of Castor commented:

“The first six months of 2021 was a transformational period for our Company, as we were able to raise $262.5 million of equity and $33.3 million of debt and grow our fleet from 6 vessels at the end of 2020 to 26 vessels on a fully delivered basis.

Strong demand for dry bulk transportation services has resulted in robust freight rates, with the upward momentum expected to be sustained by the tight vessel supply and historically low newbuilding orderbook. Following our timely acquisitions, Castor is well positioned to take advantage of this strong market with a dry bulk fleet consisting of 18 vessels, on a fully delivered basis. At the same time, most of our newly acquired tanker vessels are in either term or pool employment ensuring a high utilization for that part of our fleet.”

Earnings Commentary:

Second Quarter ended June 30, 2021 and 2020 Results

Vessel revenues, net of charterers’ commissions, for the three months ended June 30, 2021, increased to $21.8 million from $2.6 million in the same period of 2020. This increase was largely driven by the increase in our Ownership days (defined below) from 273 in the three months ended June 30, 2020 to 1,477 in the three months ended June 30, 2021, following the acquisition and delivery to our fleet of 20 vessels since June 30, 2020. The increase in vessel revenues during the three months ended June 30, 2021 as compared with the same period of 2020 was further underpinned by a stronger dry bulk shipping market resulting in higher daily TCE earned on average for our fleet

The increase in operating expenses by $6.8 million, from $1.2 million in the second quarter of 2020 to $8.0 million in the second quarter of 2021, as well as the increase in vessels’ depreciation costs by $2.5 million, from $0.3 million in the second quarter of 2020 to $2.8 million in the second quarter of 2021, mainly reflect the increase in our Ownership days following the expansion of our fleet.

Page 2

Management fees in the second quarter of 2021 amounted to $1.8 million, whereas, in the same period of 2020 management fees totalled $0.1 million. This increase in management fees is primarily due to the sizeable increase of our fleet, resulting in a substantial increase in our Ownership days for which our managers charge us with a daily management fee, following the acquisitions discussed above. Effective September 1, 2020, the daily management fee for the technical management of our fleet by Pavimar S.A. was increased from $500 to $600 per vessel, and the daily management fee for the commercial and administrative management of our fleet by Castor Ships S.A. was set to $250 per vessel.

General and administrative expenses in the second quarter of 2021 amounted to $0.7 million, whereas, in the same period of 2020 general and administrative expenses totalled $0.1 million. This increase stemmed from incurred legal and other corporate fees primarily related to the growth of our company and the $0.3 million quarterly flat fee we pay Castor Ships S.A. with effect from September 1, 2020.

During the second quarter of 2021, we incurred net interest costs and finance costs amounting to $0.5 million compared to $0.8 million during the same period in 2020.

Recent Business and Financial Developments Commentary:

Nasdaq Listing Standards Compliance Update

On June 14, 2021, Nasdaq notified us that as a result of the closing bid price of the Company’s common stock having been at $1.00 pershare or greater for at least ten consecutive business days, from May 28, 2021 to June 11, 2021, the Company has regained compliance with Nasdaq’s minimum bid price requirement for continued listing on the Nasdaq Capital Market, and the matter is now closed.

 ATM common stock offering program

On June 14, 2021, we entered into an equity distribution agreement with Maxim Group LLC acting as a sales agent, under which we may, from time to time, offer and sell shares of our common stock through the ATM program having an aggregate offering price of up to $300.0 million (the “ATM Program”). As of June 30, 2021, we had raised net proceeds of $9.7 million by issuing and selling 3,563,407 common shares under the ATM Program. Between June 30, 2021 and August 4, 2021, no sales of common shares have taken place. We intend to use the net proceeds from the sale of our common stock under the ATM Program, for capital expenditures, working capital, funding for vessel and other asset or share acquisitions or for other general corporate purposes or a combination thereof.

Financing Transactions Update

On July 23, 2021, we, through four of our ship-owning subsidiaries, entered into a $40.75 million senior secured term loan facility with a European bank which is secured by the M/V Magic Thunder, M/V Magic Nebula, M/V Magic Eclipse and the M/V Magic Twilight. The $40.75 million term loan facility has a tenor of five years and bears interest at a margin plus LIBOR. The loan was drawn down in full on July 27, 2021.

Liquidity / Financing / Cash Flow Commentary:

Our consolidated cash position as of June 30, 2021 increased by $33.3 million, to $42.7 million, in relation to our cash position on December 31, 2020. That was mainly the result of: (i) $7.2 million of positive operating cash flows during the six months ended June 30, 2021, (ii) $157.0 million of net cash proceeds pursuant to the three registered direct offerings of an aggregate 42,405,770 common shares and the concurrent private placement of an equivalent aggregate number of warrants on January 5, January 12 and April 7, 2021, (iii) proceeds of approximately $83.4 million resulting from subsequent exercises of approximately 34.4 million warrants pursuant to the June 2020, July 2020 and the January 2021 equity offerings, that resulted in the issuance of an equal number of common shares, (iv) net cash inflows of approximately $32.5 million following our entry into two secured loan facilities with two reputable European banks in January and April of 2021, (v) $9.8 million of net cash proceeds pursuant to common stock sales under the ATM Program, as offset by (vi) $1.6 of scheduled principal repayments on our existing debt agreements.

Page 4

During the six months ended June 30 2021, we used $255.1 million of the net proceeds from our first half of 2021 equity and debt financings to fund our growth and other capital expenditures.

Between July 1, 2021 and August 4, 2021, there have been no subsequent warrant exercises under our currently effective warrant schemes.

As of June 30, 2021, our total debt (including $5.0 million of related party debt maturing in September 2021), gross of unamortized deferred loan fees, was $50.2 million of which $12.5 million was repayable within one year, as compared to $18.5 million of debt as of December 31, 2020.

Fleet Employment Update (as of August 4, 2021)

Daily vessel operating expenses (6)	$	5,390		$	4,452		$	5,352		$	4,770

⁽¹⁾ Ownership days are the total number of calendar days in a period during which we owned our vessels.

⁽²⁾ Available days are the Ownership days in a period less the aggregate number of days our vessels are off-hire due to scheduled repairs, dry-dockings or special or intermediate surveys.

⁽³⁾ Operating days are the Available days in a period after subtracting off-hire and idle days.

⁽⁴⁾ Daily TCE rate is not a recognized measure under U.S. GAAP. Please refer to Appendix B of this press release for the definition and reconciliation of this measure to the most directly comparable financial measure calculated and presented in accordance with U.S. GAAP.

⁽⁵⁾ Fleet utilization is calculated by dividing the Operating days during a period by the number of Available days during that period.

⁽⁶⁾ Daily vessel operating expenses are calculated by dividing vessel operating expenses for the relevant period by the Ownership days for such period.

⁽⁷⁾ Our definitions of days (i.e. Ownership days, Available days, Operating days) may not be comparable to that reported by other companies.

 APPENDIX B

Non-GAAP Financial Information

Daily TCE Rate. TCE rate, is a measure of the average daily revenue performance of a vessel. The TCE rate is calculated by dividing total revenues (time charter and/or voyage charter revenues, net of charterers’ commissions), less voyage expenses, by the number of Available days during that period. Under a time charter, the charterer pays substantially all the vessel voyage related expenses. However, we may incur voyage related expenses when positioning or repositioning vessels before or after the period of a time charter, during periods of commercial waiting time or while off-hire during dry docking or due to other unforeseen circumstances. The TCE rate is not a measure of financial performance under U.S. GAAP (non-GAAP measure), and should not be considered as an alternative to Time charter revenues, net, the most directly comparable GAAP measure, or any other measure of financial performance presented in accordance with U.S. GAAP. However, TCE rate is a standard shipping industry performance measure used primarily to compare period-to-period changes in a company’s performance and, management believes that the TCE rate provides meaningful information to our investors since it compares daily net earnings generated by our vessels irrespective of the mix of charter types (i.e., time charter trips, time charter periods and voyage charters) under which our vessels are employed between the periods while it further assists our management in making decisions regarding the deployment and use of our vessels and in evaluating our financial performance. Our calculation of TCE rates may not be comparable to that reported by other companies. The following table reflects the calculation of our TCE rates for the periods presented (amounts in U.S. dollars, except for Available days):

	Three Months Ended June 30,						Six Months Ended June 30,
(In U.S. dollars, except for Available  Days)	2021			2020			2021			2020
Vessel revenues, net	$	21,789,783		$	2,585,659		$	28,762,636		$	5,310,936
Voyage expenses -including commissions from related party		(1,368,565	)		(104,093	)		(941,593	)		(259,600	)
TCE revenues	$	20,421,218		$	2,481,566		$	27,821,043		$	5,051,336
Available Days		1,420			273			2,030			488
TCE rate	$	14,381		$	9,090		$	13,705		$	10,351

EBITDA. We define EBITDA as earnings before interest and finance costs (if any), net of interest income, taxes (when incurred), depreciation and amortization of deferred dry-docking costs. EBITDA is used as a supplemental financial measure by management and external users of financial statements to assess our operating performance. We believe that EBITDA assists our management by providing useful information that increases the comparability of our performance operating from period to period and against the operating performance of other companies in our industry that provide EBITDA information. This increased comparability is achieved by excluding the potentially disparate effects between periods or companies of interest, other financial items, depreciation and amortization and taxes, which items are affected by various and possibly changing financing methods, capital structure and historical cost basis and which items may significantly affect net income between periods. We believe that including EBITDA as a measure of operating performance benefits investors in (a) selecting between investing in us and other investment alternatives and (b) monitoring our ongoing financial and operational strength. EBITDA is not a measure of financial performance under U.S. GAAP, does not represent and should not be considered as an alternative to net income, operating income, cash flow from operating activities or any other measure of financial performance presented in accordance with U.S. GAAP. EBITDA as presented below may not be comparable to similarly titled measures of other companies. The following table reconciles EBITDA to net (loss)/income, the most directly comparable U.S. GAAP financial measure, for the periods presented:

Significant Accounting Policies and Recent Accounting Pronouncements

2. Significant Accounting Policies and Recent Accounting Pronouncements:

A discussion of the Company's significant accounting policies can be found in the consolidated financial statements for the year ended December 31, 2020, included in the Company’s 2020 Annual Report. Apart from the below, there have been no material changes to these policies in the six-month period ended June 30, 2021.

New significant accounting policies adopted during the six months ended June 30, 2021

Segment Reporting

The Company reports financial information and evaluates its operations by charter revenues and not by the length, type of vessel or type of ship employment for its customers, i.e. time or voyage charters. The Company does not use discrete financial information to evaluate the operating results for each such type of charter or vessel. Although revenue can be identified for these types of charters or vessels, management cannot and does not identify expenses, profitability or other financial information for these various types of charters or vessels. As a result, management, including the chief operating decision maker, reviews operating results solely by revenue per day and operating results of the fleet, and thus the Company has determined that it operates as one reportable segment. Furthermore, when the Company charters a vessel to a charterer, the charterer is free to trade the vessel worldwide and, as a result, the disclosure of geographic information is impracticable.

Recent Accounting Pronouncements

There are no recent accounting pronouncements the adoption of which are expected to have a material effect on the Company’s unaudited interim consolidated condensed financial statements in the current period.

(a) Pavimar:

Each of the Company’s ship-owning subsidiaries have entered into separate vessel management agreements with Pavimar, a company controlled by Ismini Panagiotidis, the sister of Petros Panagiotidis (see Note 1). Pursuant to the terms of the management agreements, Pavimar provides the Company with a wide range of shipping services, including crew management, technical management, operational employment management, insurance arrangements, provisioning, bunkering, vessel accounting and audit support services, in exchange for a daily fee. During the six month period ended June 30, 2020, the Company’s vessels then comprising its fleet were charged with a daily management fee of $500 per day per vessel.

On September 1, 2020, the Company’s then shipowning subsidiaries entered into revised shipmanagement agreements with Pavimar which replaced the then existing shipmanagement agreements in their entirety (the “Technical Management Agreements”). Pursuant to the Technical Management Agreements, effective September 1, 2020, Pavimar provides the Company’s shipowning subsidiaries with the range of technical, crewing, insurance and operational services stipulated in the previous agreements in exchange for which Pavimar is now paid a daily fee of $600 per vessel, which shall be also subject to an annual review on their anniversary date.  The Technical Management Agreements have a term of five years and such term automatically renews for a successive five year term on each anniversary of their effective date, unless the agreements are terminated earlier in accordance with the provisions contained therein. In the event that the Technical Management Agreements are terminated by the ship-owning subsidiaries other than by reason of default by Pavimar, a termination fee equal to four times the total amount of the daily management fee calculated on an annual basis shall be payable from the ship-owning subsidiaries to Pavimar.

As of June 30, 2021, Pavimar has subcontracted the technical management of three of the Company’s dry bulk vessels and eight of its tanker vessels to third-party ship-management companies. These third-party management companies provide technical management to the respective vessels for a fixed annual fee which is paid by Pavimar at its own expense. In connection with the subcontracting services rendered by the third-party ship-management companies, the Company has as of June 30, 2021 paid Pavimar working capital guarantee deposits aggregating the amount of $1,362,646, of which $258,252 are included in Due from related party, current and $1,104,394 are presented in Due from related party, non-current in the accompanying unaudited interim consolidated balance sheets.

During the six months ended June 30, 2020 and 2021, the Company incurred management fees under the Technical Management Agreements amounting to $273,000 and $1,782,000, respectively, which are separately presented in Management fees to related parties in the accompanying unaudited interim condensed consolidated statements of comprehensive income/(loss).

In addition, Pavimar and its subcontractor third-party managers make payments for operating expenses with funds paid in advance from the Company to Pavimar. As of December 31, 2020 and June 30, 2021, amounts of $1,559,132 and $1,573,059, respectively, were due from Pavimar in relation to these working capital advances granted to it, net of payments made by Pavimar on behalf of the Company vessels.

(b) Thalassa:

$5.0 Million Term Loan Facility

Details of the Company’s loan agreement with Thalassa are discussed in Note 3 of the consolidated financial statements for the year ended December 31, 2020, included in the Company’s 2020 Annual Report.

During the six months ended June 30, 2020 and 2021, the Company incurred interest costs in connection with the $5.0 million unsecured term loan with Thalassa (the “$5.0 Million Term Loan Facility”) amounting to $151,667 and $150,833, which are included in Interest and finance costs in the accompanying unaudited interim consolidated statements of comprehensive income/(loss).

As of June 30, 2021, no amounts were prepaid under the $5.0 Million Term Loan Facility.

(c) Castor Ships:

On September 1, 2020, the Company and its shipowning subsidiaries entered into a master management agreement (the “Master Agreement”) with Castor Ships.

Equity Capital Structure

7. Equity Capital Structure:

Under the Company's articles of incorporation, the Company's authorized capital stock consists of 2,000,000,000 shares, par value $0.001 per share, of which 1,950,000,000 shares are designated as common shares and 50,000,000 shares are designated as preferred shares. For a further description of the terms and rights of the Company’s capital stock and details of its previous equity transactions please refer to Note 7 of the consolidated financial statements for the year ended December 31, 2020, included in the Company’s 2020 Annual Report.

2021 First Registered Direct Equity Offering

On December 30, 2020, the Company entered into agreements with certain unaffiliated institutional investors pursuant to which it offered and sold 9,475,000 common shares and warrants to purchase up to 9,475,000 common shares (the “2021 First Private Placement Warrants”) in a registered direct offering or the 2021 First Registered Direct Equity Offering. In connection with the 2021 First Registered Direct Equity Offering, which closed on January 5, 2021, the Company received gross and net cash proceeds of approximately $18.0 million and $16.5 million, respectively.

The 2021 First Private Placement Warrants issued in the 2021 First Registered Direct Equity Offering had a term of five years and were exercisable immediately and throughout their term for $1.90 per common share (American style option). The exercise price of the 2021 First Private Placement Warrants was subject to appropriate adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting the Company’s common shares and also upon any distributions of assets, including cash, stock or other property to existing shareholders.

As of February 10, 2021, all the 2021 First Private Placement Warrants had been exercised, and, pursuant to their exercise and the issuance by the Company of 9,475,000 common shares, the Company received gross and net proceeds of $18.0 million.

On initial recognition the fair value of the 2021 First Private Placement Warrants was $22.2 million and was determined using the Black-Scholes methodology. The fair value was considered by the Company to be classified as Level 3 in the fair value hierarchy since it was derived by unobservable inputs. The major unobservable input in connection with the valuation of the 2021 First Private Placement Warrants was the volatility used in the valuation model, which was approximated by using historical observations of the Company’s share price. The annualized historical volatility that has been applied in the 2021 First Private Placement Warrants valuation was 137.5%. A 5% increase in the volatility applied would have led to an increase of 1.7% in the fair value of the 2021 First Private Placement Warrants.

2021 Second Registered Direct Equity Offering

On January 8, 2021, the Company entered into agreements with certain unaffiliated institutional investors pursuant to which it offered and sold 13,700,000 common shares and warrants to purchase up to 13,700,000 common shares (the “2021 Second Private Placement Warrants”) in a registered direct offering or the 2021 Second Registered Direct Equity Offering. In connection with the 2021 Second Registered Direct Equity Offering, which closed on January 12, 2021, the Company received gross and net cash proceeds of approximately $26.0 million and $24.1 million, respectively.

The 2021 Second Private Placement Warrants issued in the 2021 Second Registered Direct Equity Offering had a term of five years and were exercisable immediately and throughout their term for $1.90 per common share (American style option). The exercise price of the 2021 Second Private Placement Warrants was subject to appropriate adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting the Company’s common shares and also upon any distributions of assets, including cash, stock or other property to existing shareholders.

As of February 10, 2021, all the 2021 Second Private Placement Warrants had been exercised, and, pursuant to their exercise and the issuance by the Company of 13,700,000 common shares, the Company received gross and net proceeds of $26.0 million.

On initial recognition the fair value of the 2021 Second Private Placement Warrants was $37.3 million and was determined using the Black-Scholes methodology. The fair value was considered by the Company to be classified as Level 3 in the fair value hierarchy since it was derived by unobservable inputs. The major unobservable input in connection with the valuation of the 2021 Second Private Placement Warrants was the volatility used in the valuation model, which was approximated by using historical observations of the Company’s share price. The annualized historical volatility that has been applied in the 2021 Second Private Placement Warrants valuation was 152.1%. A 5% increase in the volatility applied would have led to an increase of 1.3% in the fair value of the 2021 Second Private Placement Warrants.

2021 Third Registered Direct Equity Offering

On April 5, 2021, the Company entered into agreements with certain unaffiliated institutional investors pursuant to which it offered and sold 19,230,770 common shares and warrants to purchase up to 19,230,770 common shares (the “2021 Third Private Placement Warrants”) in a registered direct offering or the 2021 Third Registered Direct Equity Offering. In connection with the 2021 Third Registered Direct Equity Offering, which closed on April 7, 2021, the Company received gross and net cash proceeds of approximately $125.0 million and $116.3 million, respectively.

The 2021 Third Private Placement Warrants issued in the 2021 Third Registered Direct Equity Offering have a term of five years and are exercisable immediately and throughout their term for $6.50 per common share (American style option). The exercise price of the 2021 Third Private Placement Warrants is subject to appropriate adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting the Company’s common shares and also upon any distributions of assets, including cash, stock or other property to existing shareholders.

Between their issuance date and June 30, 2021, there were no exercises of the Third Private Placement Warrants and, as a result, as of June 30, 2021, 19,230,770 Third Private Placement Warrants remained unexercised and potentially issuable into common stock of the Company.

On initial recognition the fair value of the 2021 Third Private Placement Warrants was $106.6 million and was determined using the Black-Scholes methodology. The fair value was considered by the Company to be classified as Level 3 in the fair value hierarchy since it was derived by unobservable inputs. The major unobservable input in connection with the valuation of the 2021 Third Private Placement Warrants was the volatility used in the valuation model, which was approximated by using historical observations of the Company’s share price. The annualized historical volatility that has been applied in the 2021 Third Private Placement Warrants valuation was 201.7%. A 5% increase in the volatility applied would have led to an increase of 0.7% in the fair value of the 2021 Third Private Placement Warrants.

The Company accounted for the 2021 First, Second and Third Private Placement Warrants as equity in accordance with the accounting guidance under ASC 815-40. The accounting guidance provides a scope exception from classifying and measuring as a financial liability a contract that would otherwise meet the definition of a derivative if the contract is both (i) indexed to the entity's own stock and (ii) meets the equity classifications conditions. The Company concluded these warrants were equity-classified since they contained no provisions which would require the Company to account for the warrants as a derivative liability, and therefore were initially measured at fair value in permanent equity with subsequent changes in fair value not measured.

At-the-market (“ATM”) common stock offering program

On June 14, 2021, the Company, entered into an equity distribution agreement, or as commonly referred to, an at-the-market offering, with Maxim Group LLC (“Maxim”), under which the Company may sell an aggregate offering price of up to $300.0 million of its common stock with Maxim acting as a sales agent over a minimum period of 12 months (the “ATM Program”). No warrants, derivatives, or other share classes were associated with this transaction. As of June 30, 2021, the Company had received gross proceeds of $10.1 million under the ATM Program by issuing 3,563,407 common shares, whereas, the net proceeds under the ATM Program, after deducting sales commissions and other transaction fees and expenses, amounted to $9.7 million.

Issuance of common stock in connection with the Class A Warrants and the July 2020 equity offering warrants

During the six months ended June 30, 2021, the Company issued 5,546,705 common shares upon the exercise of an equivalent number of Class A Warrants issued in the June 2020 follow-on offering and 5,707,135 common shares upon the exercise of an equivalent number of warrants issued in the July 2020 follow-on equity offering. As of June 30, 2021, the Company raised $39.4 million in proceeds from the partial exercise of warrants issued in the respective equity offerings.

Reverse Stock Split

On May 28, 2021, the Company effected a 1-for-10 reverse stock split of its common stock without any change in the number of authorized common shares. All share and per share amounts, as well as warrant shares eligible for purchase under the Company's effective warrant schemes in the accompanying unaudited interim consolidated financial statements have been retroactively adjusted to reflect the reverse stock split. As a result of the reverse stock split, the number of outstanding shares as of May 28, 2021, was decreased to 89,955,848 while the par value of the Company's common shares remained unchanged to $0.001 per share.

Financial Instruments and Fair Value Disclosures

Financial Instruments and Fair Value Disclosures [Abstract]

Financial Instruments and Fair Value Disclosures

8. Financial Instruments and Fair Value Disclosures:

The principal financial assets of the Company consist of cash at banks, restricted cash, trade accounts receivable and amounts due from related party. The principal financial liabilities of the Company consist of trade accounts payable, amounts due to related parties and long-term debt (including related party debt).

The following methods and assumptions were used to estimate the fair value of each class of financial instruments:

◾ Cash and cash equivalents, restricted cash, trade accounts receivable, amounts due from related party and trade accounts payable: The carrying values reported in the accompanying unaudited interim consolidated balance sheets for those financial instruments are reasonable estimates of their fair values due to their short-term maturity nature. Cash and cash equivalents and restricted cash, current are considered Level 1 items as they represent liquid assets with short term maturities. The carrying value approximates the fair market value for interest bearing cash classified as restricted cash, non-current and is considered Level 1 item of the fair value hierarchy. The carrying value of these instruments is separately reflected in the accompanying unaudited interim consolidated balance sheets.

◾ Long-term debt: The secured credit facilities discussed in Note 6, have a recorded value which is a reasonable estimate of their fair value due to their variable interest rate and are thus considered Level 2 items in accordance with the fair value hierarchy as LIBOR rates are observable at commonly quoted intervals for the full terms of the loans. The fair value of the fixed interest bearing $5.0 Million Term Loan Facility, discussed in Note 3, determined through Level 2 inputs of the fair value hierarchy (quoted prices for identical or similar assets and liabilities in markets that are not active), approximates its recorded value as of June 30, 2021.

Concentration of credit risk: Financial instruments, which potentially subject the Company to significant concentrations of credit risk, consist principally of cash and cash equivalents and trade accounts receivable. The Company places its cash and cash equivalents, consisting mostly of deposits, with high credit qualified financial institutions. The Company performs periodic evaluations of the relative credit standing of the financial institutions in which it places its deposits. The Company limits its credit risk with accounts receivable by performing ongoing credit evaluations of its customers' financial condition.

Commitments and contingencies

9. Commitments and contingencies:

Various claims, lawsuits, and complaints, including those involving government regulations and product liability, arise in the ordinary course of the shipping business. In addition, losses may arise from disputes with charterers, agents, insurance and other claims with suppliers relating to the operations of the Company's vessels. Currently, management 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 interim consolidated financial statements.

The Company accrues for the cost of environmental liabilities when management becomes aware that a liability is probable and is able to reasonably estimate the probable exposure. Currently, management 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 interim consolidated financial statements. The Company is covered for liabilities associated with the vessels’ actions to the maximum limits as provided by Protection and Indemnity (P&I) Clubs, members of the International Group of P&I Clubs.

(a) Commitments under Contracts for BWMS Installation

On November 15, 2018, the Company entered into a contract to purchase and install BWMS on its dry bulk carriers, which was further amended on October 20, 2019 and December 8, 2020, to reflect the Company’s vessel acquisitions, as applicable in each period. The Company completed the BWMS installation on the Magic Sun during the vessel’s scheduled dry-docking which took place in the fourth quarter of 2020 and the BWMS was put into use during the second quarter of 2021. The BWMS system installations on the Magic P and the Magic Moon were granted extensions from the third quarter of 2020 to the third quarter of 2022. It is estimated that the contractual obligations related to these purchases as well as purchases on the Company’s remaining fleet vessels (where not already installed), excluding installation costs, will be approximately €0.6 million (or $0.7 million on the basis of a Euro/US Dollar exchange rate of €1.0000/$1.1904 as of June 30, 2021), of which $0.01 million are due in 2021 and $0.69 million are due in 2022. These costs will be capitalized and depreciated over the remainder of the life of each vessel.

(b) Commitments under long-term lease contracts

The following table sets forth the Company’s future minimum contracted lease payments (gross of charterers’ commissions), based on vessels’ commitments to non-cancelable fixed time charter contracts as of June 30, 2021. The calculation does not include any assumed off-hire days.

Earnings/ (Loss) Per Share

Jun. 30, 2021

Earnings/ (Loss) Per Share [Abstract]

Earnings/ (Loss) Per Share

10. Earnings/ (Loss) Per Share:

The Company calculates earnings/(loss) per share by dividing net income/(loss) available to common stockholders in each period by the weighted-average number of common shares outstanding during that period, after adjusting for the effect of cumulative dividends on the Series A Preferred Shares, whether or not earned, and only at periods when dividends on the Series A Preferred Shares are contractually allowed to accumulate. As further disclosed under Note 7 of the audited financial statements included in the 2020 Annual Report, dividends on the Series A Preferred Shares neither accrue nor accumulate during the period from July 1, 2019 until December 31, 2021 and the Company does not have any dividend priority restrictions to holders of its common shares during this period.

Diluted earnings/(loss) per share, if applicable, reflects the potential dilution that could occur if potentially dilutive instruments were exercised, resulting in the issuance of additional shares that would then share in the Company’s net income. During the six months ended June 30, 2021, the denominator of diluted earnings per common share calculation includes the incremental shares assumed issued under the treasury stock method weighted for the period the shares were outstanding with respect to warrants outstanding as of June 30, 2021. During the six months ended June 30, 2020, securities that could potentially dilute basic loss per share that were excluded from the computation of diluted loss per share, because to do so would have been antidilutive for the period presented, were the incremental shares in connection with the unexercised, as of June 30, 2020, Class A warrants, calculated in accordance with the treasury stock method.

The components of the calculation of basic and diluted earnings/(loss) per common share in each of the periods comprising the accompanying unaudited interim condensed consolidated statements of comprehensive income/(loss) are as follows:

	Six months ended June 30,			Six months ended June 30,
	2020			2021

Voyage charter revenues		—		693,471
Pool revenues		—		433,678
Total Vessel revenues	$	5,310,936	$	28,762,636

As of June 30, 2021, trade accounts receivable, net increased by $1,496,824 and deferred revenue increased by $1,564,978 compared to December 31, 2020. These changes were mainly attributable to the timing of collections and the timing of commencement of revenue recognition, the increase in charter rates and the increase in vessel revenues resultant to the growth of the Company’s fleet during the six months ended June 30, 2021. As of June 30, 2021, the Company had no deferred revenue related to undelivered performance obligations under any of its voyages in progress.

Further, as of June 30, 2021, deferred assets related to revenue contracts presented under “Deferred charges, net” amounted to $142,898 compared to $0 as of December 31, 2020 and will be expensed during the third quarter of 2021. This change was mainly attributable to the timing of commencement of revenue recognition.

Basis of Presentation

The accompanying unaudited interim condensed consolidated financial statements include the accounts of Castor and its wholly owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) for interim financial information. Accordingly, they do not include all the information and notes required by U.S. GAAP for complete financial statements. These statements and the accompanying notes should be read in conjunction with the Company’s Annual Report on Form 20-F for the fiscal year ended December 31, 2020, filed with the SEC on March 30, 2021 (the “2020 Annual Report”).

These unaudited interim condensed consolidated financial statements have been prepared on the same basis as the annual 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 six-month period ended June 30, 2021 are not necessarily indicative of the results that might be expected for the fiscal year ending December 31, 2021.

Significant Accounting Policies and Recent Accounting Pronouncements [Abstract]

Segment Reporting

Segment Reporting

The Company reports financial information and evaluates its operations by charter revenues and not by the length, type of vessel or type of ship employment for its customers, i.e. time or voyage charters. The Company does not use discrete financial information to evaluate the operating results for each such type of charter or vessel. Although revenue can be identified for these types of charters or vessels, management cannot and does not identify expenses, profitability or other financial information for these various types of charters or vessels. As a result, management, including the chief operating decision maker, reviews operating results solely by revenue per day and operating results of the fleet, and thus the Company has determined that it operates as one reportable segment. Furthermore, when the Company charters a vessel to a charterer, the charterer is free to trade the vessel worldwide and, as a result, the disclosure of geographic information is impracticable.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

There are no recent accounting pronouncements the adoption of which are expected to have a material effect on the Company’s unaudited interim consolidated condensed financial statements in the current period.
