We are offering 35,714,286 units consisting of one common share and one Class E Warrant to purchase one common share.

Each Class E Warrant will be immediately exercisable at an exercise price of $0.70 per share and expire five years after the issuance date.

We are also offering to each purchaser, with respect to the purchase of units that would otherwise result in the purchaser’s beneficial ownership exceeding 4.99% of our outstanding common shares immediately following the consummation of this offering, the opportunity to purchase units including one pre-funded warrant in lieu of one common share in the unit. Subject to limited exceptions, a holder of pre-funded warrants will not have the right to exercise any portion of its pre-funded warrants if the holder, together with its affiliates, would beneficially own in excess of 4.99% (or, at the election of the holder, such limit may be increased to up to 9.99%) of the number of common shares outstanding immediately after giving effect to such exercise. Each pre-funded warrant will be exercisable for one common share. The purchase price of each unit including a pre-funded warrant will be equal to the price per unit including one common share, minus $0.01, and the remaining exercise price of each pre-funded warrant will equal $0.01 per share. The pre-funded warrants will be immediately exercisable and may be exercised at any time until all of the pre-funded warrants are exercised in full. For each unit including a pre-funded warrant we sell (without regard to any limitation on exercise set forth therein), the number of units including a common share we are offering will be decreased on a one-for-one basis.

We are also registering the common shares included in the units and the common shares issuable from time to time upon exercise of the Class E Warrants and pre-funded warrants offered hereby.

The common shares and pre-funded warrants, if any, can each be purchased in this offering only with the accompanying Class E Warrant (other than pursuant to the option of the representative of the underwriters to purchase additional securities) as part of a unit, but the components of the units will immediately separate upon issuance.

Our common shares are listed on the Nasdaq Capital Market under the symbol “SHIP”. On August 18, 2020, the last reported sale price of our common shares on the Nasdaq Capital Market was $0.55 per share.

There is currently no established trading market for the units, pre-funded warrants, or Class E Warrants, and we do not expect one to develop.

Investing in our securities involves a high degree of risk. See “Risk Factors” beginning on page S-8 of this prospectus supplement, on page 3 of the accompanying prospectus and in our annual report on Form 20-F for the fiscal year ended December 31, 2019, which is incorporated by reference herein, to read about the risks you should consider before purchasing our securities.

Neither the U.S. Securities and Exchange Commission, or the Commission, nor any state securities commission has approved or disapproved of these securities, or determined if this prospectus supplement or the accompanying base prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The underwriters expect to deliver the units to purchasers on or about August 20, 2020.

This prospectus supplement and the accompanying prospectus are part of a registration statement that we filed with the Commission utilizing a “shelf” registration process. This document is in two parts. The first part is this prospectus supplement, which describes the specific terms of this offering and the securities offered hereby and also adds to and updates information contained in the accompanying prospectus and the documents incorporated by reference into this prospectus supplement and the accompanying prospectus. The second part, the accompanying base prospectus, gives more general information and disclosure about the securities we may offer from time to time, some of which does not apply to this offering of securities. When we refer to the prospectus, we are referring to both parts combined, and when we refer to the accompanying prospectus, we are referring to the base prospectus.

If the description of this offering varies between this prospectus supplement and the accompanying prospectus, you should rely on the information in this prospectus supplement. This prospectus supplement, the accompanying prospectus, any free writing prospectus and the documents incorporated into each by reference include important information about us and the securities being offered and other information you should know before investing. You should read this prospectus supplement and the accompanying prospectus together with the additional information described under the heading, “Where You Can Find Additional Information” in this prospectus supplement and the accompanying prospectus before investing in our securities.

Any statement made in this prospectus or in a document incorporated or deemed to be incorporated by reference into this prospectus will be deemed to be modified or superseded for purposes of this prospectus to the extent that a statement contained in this prospectus supplement or in any other subsequently filed document that is also incorporated by reference into this prospectus modifies or supersedes that statement. Any statement so modified or superseded will not be deemed, except as so modified or superseded, to constitute a part of this prospectus.

You should rely only on the information contained in or incorporated by reference in this prospectus supplement, the accompanying prospectus and any free writing prospectus. We have not authorized anyone to provide you with information that is different from the foregoing. If anyone provides you with different or inconsistent information, you should not rely on it. We are offering to sell our securities only in jurisdictions where offers and sales are permitted. You should not assume that the information contained in this prospectus supplement, the accompanying prospectus, any free writing prospectus or incorporated by reference in this prospectus supplement or the accompanying prospectus is accurate as of any date other than the date of such document. Our business, financial condition, results of operations and prospects may have changed since those dates.

Unless otherwise indicated, all references to “$” and “dollars” in this prospectus supplement are to United States dollars, and financial information presented in this prospectus is derived from financial statements that are incorporated by reference and were prepared in accordance with accounting principles generally accepted in the United States. We have a fiscal year end of December 31.

This prospectus supplement contains certain forward-looking statements made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include, but are not limited to, statements regarding our or our management’s expectations, hopes, beliefs, intentions or strategies regarding the future and other statements that are other than statements of historical fact. In addition, any statements that refer to projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements. The words “anticipate”, “believe”, “continue”, “could”, “estimate”, “expect”, “intend”, “may”, “might”, “plan”, “possible”, “potential”, “predict”, “project”, “should”, “would” and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking.

The forward-looking statements in this prospectus supplement are based upon various assumptions, many of which are based, in turn, upon further assumptions, including without limitation, management’s examination of historical operating trends, data contained in our records and other data available from third parties. Although we believe that these assumptions were reasonable when made, because these assumptions are inherently subject to significant uncertainties and contingencies which are difficult or impossible to predict and are beyond our control, we cannot assure you that we will achieve or accomplish these expectations, beliefs or projections. As a result, you are cautioned not to rely on any forward- looking statements.

In addition to these important factors and matters discussed elsewhere herein and in the documents incorporated by reference herein, important factors that, in our view, could cause actual results to differ materially from those discussed in the forward-looking statements include among other things:

These factors could cause actual results or developments to differ materially from those expressed in any of our forward-looking statements. Other unknown or unpredictable factors also could harm our results or developments. Consequently, there can be no assurance that actual results or developments anticipated by us will be realized or, even if substantially realized, that they will have the expected consequences to, or effects on, us. Given these uncertainties, prospective investors are cautioned not to place undue reliance on such forward-looking statements.

We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law. If one or more forward-looking statements are updated, no inference should be drawn that additional updates will be made with respect to those or other forward-looking statements.

We are incorporated under the laws of the Republic of the Marshall Islands and our principal executive offices are located outside the United States. The majority of the directors, officers and our independent registered public accounting firm reside outside the United States. In addition, substantially all of our assets and the assets of the directors, officers and our independent registered public accounting firm are located outside the United States. As a result, it may not be possible for you to serve legal process within the United States upon us or any of these persons. It may also not be possible for you to enforce, both in and outside the United States, judgments you may obtain in United States courts against us or these persons in any action, including actions based upon the civil liability provisions of U.S. federal or state securities laws.

Furthermore, there is substantial doubt that courts of such jurisdictions (i) would enforce judgments of U.S. courts obtained in actions against us, our directors or officers and such experts based upon the civil liability provisions of applicable U.S. federal and state securities laws or would enforce, in original actions, liabilities against us, our directors or officers and such experts based on those laws.

An investment in our securities involves a high degree of risk. Before deciding to invest in our securities, you should carefully consider the risks described in the accompanying prospectus and under the heading “Risk Factors” beginning on page 8 of our annual report on Form 20-F for the year ended December 31, 2019, which is incorporated by reference into this prospectus supplement. In addition, you should carefully consider the other information in the annual report and other documents that are incorporated by reference into this prospectus supplement. See “Where You Can Find Additional Information”. The risks and uncertainties referred to above are not the only risks and uncertainties that we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business operations. If any of these risks actually occurs, our business, financial condition and results of operations could be materially adversely affected. In that case, you may lose all or part of your investment in the securities.

Our management will have broad discretion in the application of the net proceeds from this offering and could spend the proceeds in ways that do not improve our results of operations or enhance the value of our securities. You will be relying on the judgment of our management with regard to the use of these net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the net proceeds are being used appropriately. The failure by our management to apply these funds effectively could result in financial losses that could have a material adverse effect on our business, cause the price of our securities to decline. Pending the application of these funds, we may invest the net proceeds from this offering in a manner that does not produce income or that loses value.

The warrants offered in this offering do not confer any rights of common share ownership on their holders, such as voting rights or the right to receive dividends, but rather merely represent the right to acquire common shares at a fixed price for a limited period of time. Specifically, commencing on the date of issuance, holders of the Class E Warrants may exercise their right to acquire common shares and pay an exercise price of $0.70 per share, prior to five years from the date of issuance, after which date any unexercised warrants will expire and have no further value. Commencing on the date of issuance, holders of pre-funded warrants may exercise their right to acquire common shares and pay an exercise price of $0.01, representing the unpaid portion of the exercise price. Moreover, following this offering, the market value of the warrants is uncertain and there can be no assurance that the market value of the warrants will equal or exceed the offering price. There can be no assurance that the market price of the common shares will ever equal or exceed the exercise price of the warrants, and consequently, whether it will ever be profitable for holders of the warrants to exercise the warrants.

We may issue additional common shares or other equity securities of equal or senior rank in the future without shareholder approval in connection with, among other things, future vessel acquisitions, the repayment of outstanding indebtedness, and the conversion of convertible financial instruments.

Our issuance of additional common shares or other equity securities of equal or senior rank in these situations would have the following effects:

In addition, we may be obliged to issue additional common shares pursuant to the terms of outstanding warrants and convertible notes as follows:

Our issuance of additional common shares upon the exercise of such warrants and convertible notes would cause the proportionate ownership interest in us of our existing shareholders, other than the exercising warrant or note holders, to decrease; the relative voting strength of each previously outstanding common share held by our existing shareholders to decrease; and, depending on our share price when and if these warrants or notes are exercised, may result in dilution to our shareholders.

We have issued a significant number of our common shares and may do so in the future. Shares to be issued pursuant to the exercise of our outstanding warrants, including the warrants being issued in the concurrent private placement, could cause the market price of our common shares to decline, and could have an adverse effect on our earnings per share. In addition, future sales of our common shares or other securities in the public markets, or the perception that these sales may occur, could cause the market price of our common shares to decline, and could materially impair our ability to raise capital through the sale of additional securities.

The market price of our common shares could decline due to sales, or the announcements of proposed sales, of a large number of common shares in the market, including sales of common shares by our large shareholders, or the perception that these sales could occur. These sales or the perception that these sales could occur could also depress the market price of our common shares and impair our ability to raise capital through the sale of

additional equity securities or make it more difficult or impossible for us to sell equity securities in the future at a time and price that we deem appropriate. We cannot predict the effect that future sales of common shares or other equity-related securities would have on the market price of our common shares.

Our loan agreements and other financial arrangements contain, and we expect that other future loan agreements and financing arrangements will contain, customary covenants and event of default clauses, financial covenants, restrictive covenants and performance requirements, which may affect operational and financial flexibility. Such restrictions could affect, and in many respects limit or prohibit, among other things, our ability to pay dividends, incur additional indebtedness, create liens, sell assets, or engage in mergers or acquisitions. These restrictions could limit our ability to plan for or react to market conditions or meet extraordinary capital needs or otherwise restrict corporate activities. There can be no assurance that such restrictions will not adversely affect our ability to finance our future operations or capital needs.

As a result of these restrictions, we may need to seek permission from our lenders and other financing counterparties in order to engage in some corporate actions. Our lenders’ and other financing counterparties’ interests may be different from ours and we may not be able to obtain their permission when needed. This may prevent us from taking actions that we believe are in our best interests, which may adversely impact our revenues, results of operations and financial condition.

A failure by us to meet our payment and other obligations, including our financial covenants and any security coverage requirements, could lead to defaults under our financing arrangements. Likewise, a decrease in vessel values or adverse market conditions could cause us to breach our financial covenants or security requirements (the market values of dry bulk vessels have generally experienced high volatility). In the event of a default that we cannot remedy, our lenders and other financing counterparties could then accelerate their indebtedness and foreclose on the respective vessels in our fleet. The loss of any of our vessels could have a material adverse effect on our business, results of operations and financial condition.

Because of the presence of cross-default provisions in our loan agreements, a default by us under a loan and the refusal of any one lender to grant or extend a waiver could result in the acceleration of our indebtedness under our other loans. A cross-default provision means that if we default on one loan, we would then default on our other loans containing a cross-default provision.

Between March and August 2019, we entered into supplemental agreements with certain of our lenders to amend the applicable thresholds of certain financial covenants of our credit facilities until the later of maturity or June 2020. In addition, in March 2020 we entered into supplemental agreements with one of our lenders pursuant to which certain corporate covenants were cancelled. As of June 30, 2020, we were in compliance with all original covenants relating of our loan facilities as at that date, except for (i) the asset cover ratio or (ii) the interest coverage ratio of the UniCredit Loan Facility and the ATB Loan Facility. With respect to the breaches under the UniCredit Loan Facility, the lender has confirmed that no remedies will be sought pursuant to the ongoing negotiations for a comprehensive restructuring of that facility, including to address the upcoming maturity and the deferral of two installments of $1.6 million each which were due within the first half of 2020. Furthermore, we are engaged in progressed discussions with ATB to cancel the application of the relevant covenant for the remaining duration of the ATB Loan Facility with retrospective effect from June 30, 2020, and we expect to obtain approval of such amendment within the third quarter of 2020. Concerning the upcoming maturities of the UniCredit Loan Facility and the related party facilities, we are engaged in ongoing discussions with the underlying lenders which we believe will have a positive outcome. However, there can be no assurance that these discussions will be successful, or that we will be able to obtain similar waivers and deferrals from our lenders in the future, if needed, with respect to these or future breaches.

For more information regarding our obligations under our current loan facilities, please see the sections entitled “Liquidity and Capital Resources” and “Description of Indebtedness” in Management’s Discussion and Analysis of Financial Condition and Results of Operations for the six months ended June 30, 2020, filed on Form 6-K on August 6, 2020 and incorporated by reference herein.

The World Health Organization has declared the outbreak of a novel coronavirus first identified in China and its subsequent spread around the world (COVID-19) a global pandemic. The measures taken by governments worldwide in response to the outbreak, which included numerous factory closures and restrictions on travel, as well as labor shortages resulting from the outbreak, have slowed down production of goods worldwide and decreased the amount of goods exported and imported worldwide. In addition, the increase, and potential future increase, in novel coronavirus cases in areas that constitute the main iron ore and coal exporters, such as Brazil, has resulted in lower demand for our services, leading to lower revenues, cash flow and profitability. While some economies have begun re-opening in limited capacities, it is impossible to predict the course the virus will take, how governments would respond to a second or third wave of the virus, whether an effective vaccine can be produced economically at scale, and how the behavior of our clients will change, if at all, due to the novel coronavirus pandemic’s economic shock. Some experts fear that the economic consequences of the novel coronavirus could cause a recession that outlives the pandemic.

We have thus far been affected by the novel coronavirus pandemic as follows:

Although it is too early to assess the long term impact of the novel coronavirus pandemic on global markets, and particularly on the shipping industry, the pandemic has added and is expected to add further pressure to shipping freight rates. Further depressed rates could have a material adverse impact on our business, financial condition, results of operations, and cash flows. Effects of the current pandemic may also in the future result in reduced access to capital, including the ability to refinance any existing obligations, as a result of any credit tightening generally or due to continued declines in global financial markets, including to the prices of publicly-traded securities of us, our peers and of listed companies generally. We note that future impacts cannot be reasonably estimated at this time, may take some time to materialize and may not be fully reflected in the results for the year ending December 31, 2020.

We intend to use all of the net proceeds of this offering for general corporate purposes which may include, among other things, prepaying debt or partially funding the acquisition of modern Capesize dry bulk vessels in accordance with our growth strategy. However, we do not currently have definitive plans for any debt prepayments nor have we identified any potential acquisitions, and we can provide no assurance that we will be able to complete any debt prepayment or the acquisition of any vessel that we are able to identify. We expect that the net proceeds of this offering will be approximately $22.9 million (or approximately $26.3 million if the underwriters’ option to purchase additional securities is exercised in full) in each case after deducting underwriting discounts and estimated offering expenses payable by us.

The following table sets forth our capitalization as of June 30, 2020:

There have been no significant adjustments to our capitalization since June 30, 2020, other than the adjustments described above. The historical data in the table is derived from, and should be read in conjunction with, our historical financial statements included in this prospectus. You should also read this table in conjunction with the information included in our financial results for the six months ended June 30, 2020 in our Report on Form 6-K, filed with the Commission on August 6, 2020 and is incorporated by reference herein.

The following is a summary of the material U.S. federal income tax and Marshall Islands tax consequences of the ownership and disposition of the units consisting of one common share or one pre-funded warrant and one Class E Warrant to purchase one common share, and our common shares, and of the ownership, exercise, lapse and disposition of the pre-funded warrants and Class E Warrants, and of the material U.S. federal and Marshall Islands income tax consequences applicable to us and our operations. The discussion below of the U.S. federal income tax consequences to “U.S. Holders” will apply to a beneficial owner of our common shares or warrants, as applicable, that is treated for U.S. federal income tax purposes as:

If you are not described as a U.S. Holder and are not an entity treated as a partnership or other pass-through entity for U.S. federal income tax purposes, you will be considered a “Non-U.S. Holder.” The U.S. federal income tax consequences applicable to Non-U.S. Holders is described below under the heading “United States Federal Income Taxation of Non-U.S. Holders.”

This discussion does not consider the tax treatment of partnerships or other pass-through entities or persons who hold our common shares or warrants through such entities. If a partnership (or other entity classified as a partnership for U.S. federal income tax purposes) is the beneficial owner of our common shares or warrants, the U.S. federal income tax treatment of a partner in the partnership generally will depend on the status of the partner and the activities of the partnership.

This summary is based on the U.S. Internal Revenue Code of 1986, as is in effect as of the date of this prospectus, or the Code, its legislative history, Treasury Regulations promulgated thereunder, published rulings and court decisions, all as currently in effect. These authorities are subject to change, possibly on a retroactive basis.

This summary does not address all aspects of U.S. federal income taxation that may be relevant to any particular holder based on such holder’s individual circumstances. In particular, this discussion considers only holders that will own and hold our common shares and warrants as capital assets within the meaning of Section 1221 of the Code and does not address the potential application of the alternative minimum tax or the U.S. federal income tax consequences to holders that are subject to special rules, including:

This summary does not address any aspect of U.S. federal non-income tax laws, such as gift or estate tax laws, or state, local or non-U.S. tax laws.

We have not sought, nor do we intend to seek, a ruling from the Internal Revenue Service, or the IRS, as to any U.S. federal income tax consequence described herein. The IRS may disagree with the description herein, and its determination may be upheld by a court.

Because of the complexity of the tax laws and because the tax consequences to any particular holder of our common shares and warrants may be affected by matters not discussed herein, each such holder is urged to consult with its tax advisor with respect to the specific tax consequences of the ownership and disposition of our common shares and warrants, including the applicability and effect of state, local and non-U.S. tax laws, as well as U.S. federal tax laws.

Unless exempt from United States federal income taxation under the rules discussed below, a foreign corporation is subject to United States federal income taxation in respect of any income that is derived from the use of vessels, from the hiring or leasing of vessels for use on a time, voyage or bareboat charter basis, from the participation in a shipping pool, partnership, strategic alliance, joint operating agreement, code sharing arrangements or other joint venture it directly or indirectly owns or participates in that generates such income, or from the performance of services directly related to those uses, which we refer to as “shipping income,” to the extent that the shipping income is derived from sources within the United States. For these purposes, 50% of the gross shipping income that is attributable to transportation that begins or ends, but that does not both begin and end, in the United States, exclusive of certain U.S. territories and possessions, constitutes income from sources within the United States, which we refer to as “U.S. source gross shipping income.”

Shipping income attributable to transportation that both begins and ends in the United States is considered to be 100% from sources within the United States. We are prohibited by law from engaging in transportation that produces income considered to be 100% from sources within the United States.

Shipping income attributable to transportation exclusively between non-U.S. ports will be considered to be 100% derived from sources outside the United States. Shipping income derived from sources outside the United States will not be subject to any United States federal income tax.

For our 2019 taxable year, we had U.S. source gross shipping income of approximately $3,688,713.

We are subject to a 4% tax imposed without allowance for deductions for such taxable year, as described in “—Taxation in Absence of Exemption”, unless we qualify for exemption from tax under Section 883 of the Code, the requirements of which are described in detail below. For our 2019 taxable year, we were subject to a U.S federal tax of $147,548.

Under Section 883 of the Code and the regulations thereunder, we will be exempt from United States federal income taxation on our U.S.-source shipping income if:

The jurisdictions where we and our ship-owning subsidiaries are incorporated grant “equivalent exemptions” to United States corporations. Therefore, we will be exempt from United States federal income taxation with respect to our U.S. source shipping income if we satisfy either the 50% Ownership Test or the Publicly-Traded Test.

Under the regulations, a foreign corporation will satisfy the 50% Ownership Test for a taxable year if (i) for at least half of the number of days in the taxable year, more than 50% of the value of its shares is owned, directly or constructively through the application of certain attribution rules prescribed by the regulations, by one or more shareholders who are residents of foreign countries that grant “equivalent exemption” to corporations organized in the United States and (ii) the foreign corporation satisfies certain substantiation and reporting requirements with respect to such shareholders. Holders of warrants will not be treated as constructive owners of shares for purposes of the 50% Ownership Test.

We did not satisfy the 50% Ownership Test for our 2019 taxable year. Furthermore, these substantiation requirements are onerous and therefore there can be no assurance that we would be able to satisfy them, even if our share ownership would otherwise satisfy the requirements of the 50% Ownership Test.

The regulations provide that the stock of a foreign corporation will be considered to be “primarily traded” on an established securities market in a country if the number of shares of each class of stock used to satisfy the Publicly-Traded Test that is traded during the taxable year on all established securities markets in that country exceeds the number of shares in each such class that is traded during that year on established securities markets in any other single country.

Under the regulations, the stock of a foreign corporation will be considered “regularly traded” if one or more classes of its stock representing 50% or more of its outstanding shares, by total combined voting power of all classes of stock entitled to vote and by total combined value of all classes of stock, are listed on one or more established securities markets (such as Nasdaq Capital Market), which we refer to as the “listing threshold.”

The regulations further require that with respect to each class of stock relied upon to meet the listing requirement: (i) such class of the stock is traded on the market, other than in minimal quantities, on at least sixty (60) days during the taxable year or one-sixth (1/6) of the days in a short taxable year; and (ii) the aggregate number of shares of such class of stock traded on such market is at least 10% of the average number of shares of such class of stock outstanding during such year or as appropriately adjusted in the case of a short taxable year. Even if a foreign corporation does not satisfy both tests, the regulations provide that the trading frequency and trading volume tests will be deemed satisfied by a class of stock if such class of stock is traded on an established market in the United States and such class of stock is regularly quoted by dealers making a market in such stock.

Notwithstanding the foregoing, the regulations provide, in pertinent part, that a class of stock will not be considered to be “regularly traded” on an established securities market for any taxable year in which 50% or more of the vote and value of the outstanding shares of such class of stock are owned, actually or constructively under specified attribution rules, on more than half the days during the taxable year by persons who each own directly or indirectly 5% or more of the vote and value of such class of stock, whom we refer to as “5% Shareholders”. We refer to this restriction in the regulations as the “Closely-Held Rule”.

For purposes of being able to determine our 5% Shareholders, the regulations permit a foreign corporation to rely on Schedule 13G and Schedule 13D filings with the Commission. The regulations further provide that an investment company that is registered under the Investment Company Act of 1940, as amended, will not be treated as a 5% Shareholder for such purposes.

The Closely-Held Rule will not disqualify a foreign corporation, however, if it can establish or substantiate that qualified shareholders own, actually or constructively under specified attribution rules, sufficient shares in the closely-held block of stock to preclude the shares in the closely-held block that are owned by non-qualified 5% Shareholders from representing 50% or more of the value of such class of stock for more than half of the days during the tax year. These substantiation requirements are onerous and consequently there can be no assurance that we would be able to satisfy them with respect to any taxable year. We do not believe that we satisfied that less than 50% of our shares were held for more than half of the days in the 2019 taxable year by non-qualified 5% Shareholders. Additionally, holders of warrants will not be treated as constructive owners of shares for purposes of the Closely-Held Rule.

Due to the factual nature of the issues involved, there can be no assurance that we or any of our subsidiaries will qualify for the benefits of Section 883 of the Code for future taxable years.

To the extent the benefits of Section 883 are unavailable, our U.S. source gross shipping income, to the extent not considered to be “effectively connected” with the conduct of a U.S. trade or business, as described below, would be subject to a 4% tax imposed by Section 887 of the Code on a gross basis, without the benefit of deductions, otherwise referred to as the “4% Tax.” Since under the sourcing rules described above, no more than 50% of our shipping income would be treated as being derived from U.S. sources, the maximum effective rate of U.S. federal income tax on our shipping income would never exceed 2% under the 4% Tax.

To the extent the benefits of the Section 883 exemption are unavailable and our U.S. source gross shipping income is considered to be “effectively connected” with the conduct of a U.S. trade or business, as described below, any such “effectively connected” U.S. source gross shipping income, net of applicable deductions, would be subject to the U.S. federal corporate income tax currently imposed at a rate of 21%. In addition, we may be subject to the 30% “branch profits” tax on earnings effectively connected with the conduct of such trade or business, as determined after allowance for certain adjustments, and on certain interest paid or deemed paid attributable to the conduct of our U.S. trade or business.

Our U.S. source gross shipping income would be considered “effectively connected” with the conduct of a U.S. trade or business only if:

We do not intend to have, or permit circumstances that would result in having, any vessel operating to the United States on a regularly scheduled basis, or earning income from the leasing of a vessel attributable to a fixed place of business in the United States. Based on the foregoing and on the expected mode of our shipping operations and other activities, we believe that none of our U.S. source gross shipping income will be “effectively connected” with the conduct of a U.S. trade or business.

Regardless of whether we qualify for exemption under Section 883, we will not be subject to United States federal income taxation with respect to gain realized on a sale of a vessel, provided the sale is considered to occur outside of the United States under United States federal income tax principles. In general, a sale of a vessel will be considered to occur outside of the United States for this purpose if title to the vessel, and risk of loss with respect to the vessel, pass to the buyer outside of the United States. It is expected that any sale of a vessel by us will be considered to occur outside of the United States.

No statutory, administrative or judicial authority directly addresses the treatment of a unit or instruments similar to a unit for U.S. federal income tax purposes and, therefore, that treatment is not entirely clear. The acquisition of a unit should be treated for U.S. federal income tax purposes as the acquisition of one common share or one pre-funded warrant and one Class E Warrant. For U.S. federal income tax purposes, each holder of a unit must allocate the purchase price paid by such holder for such unit between the common share or pre-funded warrant and Class E Warrant based on the relative fair market value of each at the time of issuance. Under U.S. federal income tax law, each investor must make his or her own determination of such value based on all the relevant facts and circumstances. Therefore, we strongly urge each investor to consult his or her tax adviser regarding the determination of value for these purposes. The price allocated to each common share or pre-funded warrant and each Class E Warrant should be the shareholder’s tax basis in such share or pre-funded warrant and each Class E Warrant, as the case may be. Any disposition of a unit should be treated for U.S. federal income tax purposes as a disposition of the common share or pre-funded warrant and Class E Warrant comprising the unit, and the amount realized on the disposition should be allocated between the common share or pre-funded warrant and Class E Warrant based on their respective relative fair market values at the time of disposition (as determined by each such unit holder based on all relevant facts and circumstances). The separation of the common share or pre-funded warrant and the Class E Warrant comprising a unit should not be a taxable event for U.S. federal income tax purposes.

The foregoing treatment of the common shares, pre-funded warrants and Class E Warrants and a holder’s purchase price allocation are not binding on the IRS or the courts. Because there are no authorities that directly address instruments that are similar to the units, no assurance can be given that the IRS or the courts will agree with the characterization described above or the discussion below. Accordingly, each prospective investor is urged to consult its own tax advisors regarding the tax consequences of an investment in a unit (including alternative characterizations of a unit). The balance of this discussion assumes that the characterization of the units described above is respected for U.S. federal income tax purposes.

We believe that our pre-funded warrants should be treated as our common shares for U.S. federal income tax purposes, rather than warrants. Assuming this position is upheld, no gain or loss should be recognized upon the exercise of a pre-funded warrant and, upon exercise, the holding period of a pre-funded warrant should carry over to the common share received. Similarly, the tax basis of a pre-funded warrant should carry over to the common share received upon exercise, increased by the exercise price of $0.01 per share. However, our position is not binding on the IRS and the IRS may treat the pre-funded warrants as warrants to acquire our common shares. You should consult your tax advisor regarding the U.S. federal tax consequences of an investment in the pre-funded warrants. The following discussion assumes our pre-funded warrants are properly treated as our common shares.

Subject to the passive foreign investment company, or PFIC, rules discussed below, any distributions made by us with respect to common shares to a U.S. Holder will generally constitute dividends, which may be taxable as ordinary income or “qualified dividend income” as described in more detail below, to the extent of our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Distributions in excess of our earnings and profits will be treated first as a non-taxable return of capital to the extent of the U.S. Holder’s tax basis in his common shares on a dollar-for-dollar basis and thereafter as capital gain. Because we are not a U.S. corporation, U.S. Holders that are corporations will generally not be entitled to claim a dividends-received deduction with respect to any distributions they receive from us.

Dividends paid on common shares to a U.S. Holder which is an individual, trust, or estate (a “U.S. Non-Corporate Holder”) will generally be treated as “qualified dividend income” that is taxable to such shareholders at preferential U.S. federal income tax rates provided that (1) the common shares are readily tradable on an established securities market in the United States (such as Nasdaq Capital Market on which the common shares are currently listed); (2) we are not a passive foreign investment company, or PFIC, for the taxable year during which the dividend is paid or the immediately preceding taxable year (which we do not

believe we are or have been, and do not expect to be); (3) the U.S. Non-Corporate Holder has owned the common shares for more than 60 days in the 121-day period beginning 60 days before the date on which the common shares become ex-dividend; and (4) certain other conditions are met.

Any dividends paid by us which are not eligible for these preferential rates will be taxed as ordinary income to a U.S. Holder.

Special rules may apply to any “extraordinary dividend”—generally, a dividend in an amount which is equal to or in excess of 10% of a shareholder’s adjusted basis in a common share—paid by us. If we pay an “extraordinary dividend” on our common shares that is treated as “qualified dividend income,” then any loss derived by a U.S. Non-Corporate Holder from the sale or exchange of such common shares will be treated as long-term capital loss to the extent of such dividend.

Assuming we do not constitute a PFIC for any taxable year, a U.S. Holder generally will recognize taxable gain or loss upon a sale, exchange or other disposition of our common shares or warrants in an amount equal to the difference between the amount realized by the U.S. Holder from such sale, exchange or other disposition and the U.S. Holder’s tax basis in such shares or warrants. Such gain or loss will be treated as long-term capital gain or loss if the U.S. Holder’s holding period in the common shares or warrants is greater than one year at the time of the sale, exchange or other disposition. A U.S. Holder’s ability to deduct capital losses is subject to certain limitations.

Neither we nor a U.S. Holder of a warrant will recognize gain or loss as a result of the U.S. Holder’s receipt of our common shares upon exercise of a warrant. A U.S. Holder’s adjusted tax basis in the common shares received will be an amount equal to the sum of (i) the U.S. Holder’s adjusted tax basis in the warrant exercised and (ii) the amount of the exercise price for the warrant. If the warrants lapse without being exercised, the U.S. Holder will recognize capital loss in the amount equal to the U.S. Holder’s adjusted tax basis in the warrants. A U.S. Holder’s holding period for common shares received upon exercise of a warrant (other than a pre-funded warrant) will commence on the date the warrant is exercised.

The exercise price of a warrant is subject to adjustment under certain circumstances. If an adjustment increases a proportionate interest of the holder of a warrant in the fully diluted common shares without proportionate adjustments to the holders of our common shares, U.S. Holder of the warrants may be treated as having received a constructive distribution, which may be taxable to the U.S. Holder as a dividend.

The tax consequences of holding and disposing of our common shares is discussed above. U.S. Holders of our warrants should also carefully review the section titled “Passive Foreign Investment Company Rules” as a U.S. Holder generally will not be able to make a QEF election with respect to the warrants if we are a PFIC.

Special U.S. federal income tax rules apply to a U.S. Holder that holds stock, or is treated as holding stock by application of certain attribution rules (for instance, treating options or warrants as stock), in a foreign corporation classified as a PFIC for U.S. federal income tax purposes. In general, we will be treated as a PFIC with respect to a U.S. Holder if, for any taxable year in which such holder held our common shares or warrants, either:

For purposes of determining whether we are a PFIC, we will be treated as earning and owning our proportionate share of the income and assets, respectively, of any of our subsidiary corporations in which we own at least 25% of the value of the subsidiary’s stock. Income earned, or deemed earned, by us in connection with the performance of services should not constitute passive income. By contrast, rental income, which includes bareboat hire, would generally constitute “passive income” unless we are treated under specific rules as deriving rental income in the active conduct of a trade or business.

Based on our current operations and future projections, we do not believe that we are or have been a PFIC during our 2019 taxable year, nor do we expect to become a PFIC with respect to our 2020 taxable year or any future taxable year. Although there is no legal authority directly on point, our belief is based principally on the position that, for purposes of determining whether we are a PFIC, the gross income we derive or are deemed to derive from the time chartering and voyage chartering activities of our wholly-owned subsidiaries should constitute services income, rather than rental income. Correspondingly, we believe that such income does not constitute passive income, and the assets that we or our wholly-owned subsidiaries own and operate in connection with the production of such income, in particular, the vessels, do not constitute passive assets for purposes of determining whether we are a PFIC. We believe there is substantial legal authority supporting our position consisting of case law and Internal Revenue Service pronouncements concerning the characterization of income derived from time charters and voyage charters as services income for other tax purposes. However, there is also authority which characterizes time charter income as rental income rather than services income for other tax purposes. It should be noted that in the absence of any legal authority specifically relating to the statutory provisions governing PFICs, the Internal Revenue Service or a court could disagree with this position. In addition, although we intend to conduct our affairs in a manner so as to avoid being classified as a PFIC with respect to any taxable year, there can be no assurance that the nature of our operations will not change in the future.

As discussed more fully below, if we were to be treated as a PFIC for any taxable year, a U.S. Holder would be subject to different taxation rules depending on whether the U.S. Holder of our common shares (but not our warrants, other than pre-funded warrants) makes an election to treat us as a “Qualified Electing Fund,” which election is referred to as a “QEF election.” As an alternative to making a QEF election, a U.S. Holder of our common shares (but not our warrants, other than pre-funded warrants) should be able to make a “mark-to-market” election with respect to the common shares, as discussed below. In addition, if we were to be treated as a PFIC, a U.S. Holder would be required to file an IRS Form 8621 with respect to such holder’s common shares.

If a U.S. Holder of our common shares (including pre-funded warrants) makes a timely QEF election, which U.S. Holder is referred to as an “Electing Holder,” the Electing Holder must report each year for U.S. federal income tax purposes its pro rata share of our ordinary earnings and our net capital gain, if any, for our taxable year that ends with or within the taxable year of the Electing Holder, regardless of whether or not distributions were received from us by the Electing Holder. The Electing Holder’s adjusted tax basis in the common shares will be increased to reflect taxed but undistributed earnings and profits. Distributions of earnings and profits that had been previously taxed will result in a corresponding reduction in the adjusted tax basis in the common shares and will not be taxed again once distributed. An Electing Holder would generally recognize capital gain or loss on the sale, exchange or other disposition of the common shares. A U.S. Holder would make a QEF election with respect to any year that we are a PFIC by filing IRS Form 8621 with his, her or its U.S. federal income tax return. After the end of each taxable year, we will determine whether we were a PFIC for such taxable year. If we determine or otherwise become aware that we are a PFIC for any taxable year, we will use commercially reasonable efforts to provide each U.S. Holder with all necessary information, including a PFIC Annual Information Statement, in order to enable such holder to make a QEF election for such taxable year. A U.S. Holder will not be able to make a QEF election in respect of our warrants (other than pre-funded warrants). U.S. Holders of our common shares or warrants are urged to consult their own tax advisors regarding the application of the PFIC rules and the QEF rules to them.

Alternatively, if we were to be treated as a PFIC for any taxable year and, as anticipated, our common shares are treated as “marketable stock,” a U.S. Holder would be allowed to make a “mark-to-market” election with respect to our common shares. If that election is made, the U.S. Holder generally would include as ordinary income in each taxable year the excess, if any, of the fair market value of the common shares at the end of the taxable year over such U.S. Holder’s adjusted tax basis in the common shares. The U.S. Holder would also be permitted an ordinary loss in respect of the excess, if any, of the U.S. Holder’s adjusted tax basis in the common shares over its fair market value at the end of the taxable year, but only to the extent of the net amount previously included in income as a result of the mark-to-market election. A U.S. Holder’s tax basis in his

common shares would be adjusted to reflect any such income or loss amount. Gain realized on the sale, exchange or other disposition of the common shares would be treated as ordinary income, and any loss realized on the sale, exchange or other disposition of the common shares would be treated as ordinary loss to the extent that such loss does not exceed the net mark-to-market gains previously included by the U.S. Holder. The mark-to-market election is generally unavailable to U.S. Holders of our warrants, other than pre-funded warrants.

Finally, if we were to be treated as a PFIC for any taxable year, a U.S. Holder who does not make either a timely QEF election or a timely “mark-to-market” election for that year, whom we refer to as a “Non-Electing Holder,” would be subject to special rules with respect to (1) any excess distribution (i.e., the portion of any distributions received by the Non-Electing Holder on our common shares in a taxable year in excess of 125 percent of the average annual distributions received by the Non-Electing Holder in the three preceding taxable years, or, if shorter, the Non-Electing Holder’s holding period for the common shares), and (2) any gain realized on the sale, exchange or other disposition of our common shares or warrants. Under these special rules:

These penalties would not apply to a pension or profit sharing trust or other tax-exempt organization that did not borrow funds or otherwise utilize leverage in connection with its acquisition of our common shares or warrants. If a Non-Electing Holder who is an individual dies while owning our common shares, such Non-Electing Holder’s successor generally would not receive a step-up in tax basis with respect to such common shares or warrants.

A U.S. Holder that is an individual or estate, or a trust that does not fall into a special class of trusts that is exempt from such tax, is subject to a 3.8% tax on the lesser of (1) such U.S. Holder’s “net investment income” (or undistributed “net investment income” in the case of estates and trusts) for the relevant taxable year and (2) the excess of such U.S. Holder’s modified adjusted gross income for the taxable year over a certain threshold (which in the case of individuals will be between $125,000 and $250,000, depending on the individual’s circumstances). A U.S. Holder’s net investment income will generally include its gross dividend income and its net gains from the disposition of the common shares, unless such dividends or net gains are derived in the ordinary course of the conduct of a trade or business (other than a trade or business that consists of certain passive or trading activities). Net investment income generally will not include a U.S. Holder’s pro rata share of the Company’s income and gain (if we are a PFIC and that U.S. Holder makes a QEF election, as described above in “—Taxation of U.S. Holders Making a Timely QEF or Mark-to Market Election”). However, a U.S. Holder may elect to treat inclusions of income and gain from a QEF election as net investment income. Failure to make this election could result in a mismatch between a U.S. Holder’s ordinary income and net investment income. If you are a U.S. Holder that is an individual, estate or trust, you are urged to consult your tax advisor regarding the applicability of the net investment income tax to your income and gains in respect of your investment in our common shares or warrants.

Dividends paid to a Non-U.S. Holder with respect to our common shares generally should not be subject to U.S. federal income tax, unless the dividends are effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, are attributable to a permanent establishment or fixed base that such holder maintains in the United States).

In addition, a Non-U.S. Holder generally should not be subject to U.S. federal income tax on any gain attributable to a sale or other disposition of our common shares or warrants unless such gain is effectively

connected with its conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, is attributable to a permanent establishment or fixed base that such holder maintains in the United States) or the Non-U.S. Holder is an individual who is present in the United States for 183 days or more in the taxable year of sale or other disposition and certain other conditions are met (in which case such gain from United States sources may be subject to tax at a 30% rate or a lower applicable tax treaty rate).

Dividends and gains that are effectively connected with the Non-U.S. Holder’s conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, are attributable to a permanent establishment or fixed base in the United States) generally should be subject to tax in the same manner as for a U.S. Holder and, if the Non-U.S. Holder is a corporation for U.S. federal income tax purposes, it also may be subject to an additional branch profits tax at a 30% rate or a lower applicable tax treaty rate.

A Non-U.S. Holder will generally not be subject to U.S. federal income tax upon the acquisition, holding, exercise or lapse of our warrants.

In general, information reporting for U.S. federal income tax purposes should apply to distributions made on our common shares within the United States to a non-corporate U.S. Holder and to the proceeds from sales and other dispositions of our common shares or warrants to or through a U.S. office of a broker by a non-corporate U.S. Holder. Payments made (and sales and other dispositions effected at an office) outside the United States will be subject to information reporting in limited circumstances.

In addition, backup withholding of U.S. federal income tax, currently at a rate of 24%, generally should apply to distributions paid on our common shares to a non-corporate U.S. Holder and the proceeds from sales and other dispositions of our common shares or warrants by a non-corporate U.S. Holder, who:

A Non-U.S. Holder generally may eliminate the requirement for information reporting and backup withholding by providing certification of its foreign status, under penalties of perjury, on a duly executed applicable IRS Form W-8 or by otherwise establishing an exemption.

Backup withholding is not an additional tax. Rather, the amount of any backup withholding generally should be allowed as a credit against a U.S. Holder’s or a Non-U.S. Holder’s U.S. federal income tax liability and may entitle such holder to a refund, provided that certain required information is timely furnished to the IRS.

Individuals who are U.S. Holders (and to the extent specified in applicable Treasury regulations, certain individuals who are Non-U.S. Holders and certain U.S. entities) who hold “specified foreign financial assets” (as defined in Section 6038D of the Code) are required to file IRS Form 8938 with information relating to the asset for each taxable year in which the aggregate value of all such assets exceeds $75,000 at any time during the taxable year or $50,000 on the last day of the taxable year (or such higher dollar amount as prescribed by applicable Treasury regulations). Specified foreign financial assets would include, among other assets, the common shares, unless the shares held through an account maintained with a U.S. financial institution. Substantial penalties apply to any failure to timely file IRS Form 8938, unless the failure is shown to be due to reasonable cause and not due to willful neglect. Additionally, in the event an individual U.S. Holder (and to the extent specified in applicable Treasury regulations, an individual Non-U.S. Holder or a U.S. entity) that is required to file IRS Form 8938 does not file such form, the statute of limitations on the assessment and collection of U.S. federal income taxes of such holder for the related tax year may not close until three years after the date that the required information is filed. U.S. Holders (including U.S. entities) and Non-U.S. Holders are encouraged consult their own tax advisors regarding their reporting obligations under this legislation.

We are incorporated in the Republic of the Marshall Islands. Under current Marshall Islands law, we are not subject to tax on income or capital gains, no Marshall Islands withholding tax will be imposed upon payment of dividends by us to its shareholders, and holders of our common shares that are not residents of or domiciled or carrying on any commercial activity in the Marshall Islands will not be subject to Marshall Islands tax on the sale or other disposition of our common shares.

We are offering 35,714,286 units, each unit consisting of one common share and one Class E Warrant to purchase one common share. We have also granted the underwriters in this offering an option for a period of 45 days to purchase up to 5,357,142 additional common shares and/or pre-funded warrants and/or 5,357,142 additional Class E Warrants from us.

We are also offering to each purchaser whose purchase of common shares in this offering would otherwise result in the purchaser, together with its affiliates, beneficially owning more than 4.99% of our outstanding common shares immediately following the consummation of this offering, the opportunity to purchase, if the purchaser so chooses, pre-funded warrants, in lieu of common shares that would otherwise result in the purchaser’s beneficial ownership exceeding 4.99% of our outstanding common shares. For each pre-funded warrant we sell (without regard to any limitation on exercise set forth therein), the number of common shares we are offering will be decreased on a one-for-one basis. Subject to limited exceptions, a holder of pre-funded warrants will not have the right to exercise any portion of its pre-funded warrants if the holder, together with its affiliates, would beneficially own in excess of 4.99% (or, at the election of the holder, such limit may be increased to up to 9.99%) of the number of common shares outstanding immediately after giving effect to such exercise. Each pre-funded warrant is being sold together with a Class E Warrant with the same terms as the Class E Warrants accompanying the common shares. Because one Class E Warrant is being sold together in this offering with each common share or, in the alternative, each pre-funded warrant to purchase one common share, the number of Class E Warrants sold in this offering will not change as a result of a change in the mix of the common shares and pre-funded warrants sold.

We are also registering the common shares included in the units and the common shares issuable from time to time upon exercise of the warrants offered hereby. The units offered hereby have no stand-alone rights and will not be certificated or issued as stand-alone securities. The common shares (or pre-funded warrants) and the Class E Warrants comprising the units are immediately separable and will be issued separately in this offering.

The following summary of certain terms and provisions of the warrants offered hereby is not complete and is subject to, and qualified in its entirety by the provisions of the forms of warrant and warrant agency agreement, which are filed as exhibits to the registration statement of which this prospectus forms a part. Prospective investors should carefully review the terms and provisions set forth in such forms of warrant and warrant agency agreement.

Exercisability. The warrants are exercisable at any time after their original issuance and at any time, for the Class E Warrants, up to the date that is five years after their original issuance date, and, for the pre-funded warrants, until exercised in full. The warrants will be exercisable, at the option of each holder, in whole or in part by delivering to us a exercise notice in accordance with the terms of the warrant and, at any time a registration statement registering the issuance of the common shares underlying the warrants under the Securities Act is effective and available for the issuance of such shares, or an exemption from registration under the Securities Act is available for the issuance of such shares, by payment in full in immediately available funds for the number of common shares purchased upon such exercise. If a registration statement registering the issuance of the common shares underlying the warrants under the Securities Act is not effective or available and an exemption from registration under the Securities Act is not available for the issuance of such shares, the holder may, in its sole discretion, elect to exercise the warrant through a cashless exercise, in which case the holder would receive upon such exercise the net number of common shares determined according to the formula set forth in the warrant. We may be required to pay certain amounts as liquidated damages as specified in the warrants in the event we do not deliver common shares upon exercise of the warrants within the time periods specified in the warrants. No fractional common shares will be issued in connection with the exercise of a warrant, and we will issue a number of common shares equal to the number of common shares which a warrant holder would otherwise be entitled to purchase upon such exercise, rounded down to the nearest whole share.

Exercise Limitation. A holder will not have the right to exercise any portion of the warrant if the holder (together with its affiliates) would beneficially own in excess of 4.99% (or, upon election of the holder, 9.99%) of the number of shares of our common shares outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the warrants. However, any holder may increase or decrease such percentage, but not in excess of 9.99%, provided that any increase will not be effective until the 61^st day after such election.

Exercise Price. The exercise price per whole common share purchasable upon exercise of the warrants is $0.70 per share. The exercise price and number of common shares issuable on exercise of the Class E Warrants is subject to appropriate adjustments in the event of certain dividends, distributions and rights offerings to our common shareholders, stock splits, stock combinations, reclassifications or similar events affecting our common shares. The exercise price of the Class E Warrants may also be reduced to any amount and for any period of time at the sole discretion of our board of directors. The exercise price for the pre-funded warrants is $0.01 per share and the exercise price and number of common shares issuable on exercise of the pre-funded warrants will adjust in the event of certain stock splits, stock combinations, reclassifications or similar events affecting our common shares. The holders of pre-funded warrants also will have the right to participate on an as-exercised basis in certain dividends, distributions and rights offerings to our common shareholders.

Transferability. Subject to applicable laws, the pre-funded warrants and Class E Warrants may be offered for sale, sold, transferred or assigned without our consent.

Exchange Listing. We do not intend to apply for the listing of the Class E Warrants or the pre-funded warrants on any stock exchange. Without an active trading market, the liquidity of the Class E Warrants and the pre-funded warrants will be limited.

Warrant Agent. The Class E Warrants will be issued in registered form under a warrant agreement between Continental Stock Transfer & Trust, as warrant agent, and us. The warrants shall initially be represented only by one or more global warrants deposited with the warrant agent, as custodian on behalf of The Depository Trust Company (DTC) and registered in the name of Cede & Co., a nominee of DTC, or as otherwise directed by DTC.

Fundamental Transactions. In the event of a fundamental transaction, as described in the warrants and generally including, with certain exceptions, any reorganization, recapitalization or reclassification of our common shares, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger with or into another person, the acquisition of more than 50% of our outstanding common shares, or any person or group becoming the beneficial owner of 50% of the voting power represented by our outstanding common shares, the holders of the warrants will be entitled to receive upon exercise of the warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the warrants immediately prior to such fundamental transaction.

Rights as a Shareholder. Except as otherwise provided in the warrants or by virtue of such holder’s ownership of our common shares, the holder of a warrant does not have the rights or privileges of a holder of our common shares, including any voting rights, until the holder exercises the warrant.

Governing Law. The pre-funded warrants, the Class E Warrants and the warrant agreement are governed by New York law.

We have entered into an underwriting agreement with Maxim Group LLC (the “Representative”), as representative of the underwriters listed below, dated August 17, 2020. Subject to the terms and conditions of the underwriting agreement, we have agreed to sell to each underwriter named below, and each underwriter below has severally agreed to purchase, at the public offering price less the underwriting discounts set forth on the cover page of this prospectus, the number of units listed next to its name in the following table:

The underwriters are committed to purchase all of the units offered by us other than those covered by the over-allotment option described below, if they purchase any units. The obligations of the underwriters may be terminated upon the occurrence of certain events specified in the underwriting agreement. Furthermore, pursuant to the underwriting agreement, the underwriters’ obligations are subject to customary conditions, representations and warranties contained in the underwriting agreement, such as receipt by the underwriters of officers’ certificates and legal opinions.

We have agreed to indemnify the underwriters against specified liabilities, including liabilities under the Securities Act, and to contribute to payments the underwriters may be required to make in respect thereof.

The underwriters are offering the units, subject to prior sale, when, as and if issued to and accepted by it, subject to approval of legal matters by its counsel and other conditions specified in the underwriting agreement. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

We have granted a 45-day option to the Representative, exercisable one or more times in whole or in part, to purchase up to 5,357,142 additional common shares and/or pre-funded warrants and/or 5,357,142 additional Class E Warrants, less the underwriting discounts and commissions, to cover over-allotments, if any.

The following table shows the per unit and total underwriting discounts and commissions to be paid to the underwriters. Such amounts are shown assuming both no exercise and full exercise of the underwriters’ option to purchase additional securities.

The underwriters propose to offer the units offered by us to the public at the public offering price set forth on the cover of this prospectus. In addition, the underwriters may offer some of the units to other securities dealers at such price less a concession of $0.024 per unit. If all of the units offered by us are not sold at the public offering price, the Representative may change the offering price and other selling terms by means of a supplement to this prospectus.

We have also agreed to pay the following expenses of the Representative relating to the offering: (a) all filing fees and communication expenses associated with the review of this offering by FINRA; (b) all fees,

expenses and disbursements relating to background checks of our officers and directors in an amount not to exceed $5,000 in the aggregate; and (c) fees for underwriters’ counsel; in an aggregate amount not to exceed $75,000.

The estimated offering expenses payable by us, exclusive of the underwriting discounts and commissions, are approximately $300,000. This amount includes the Representative’s accountable expenses, including legal fees for Representative’s legal counsel, that we have agreed to pay at the closing of the offering in an aggregate amount of up to $75,000.

The underwriters do not intend to confirm sales of the securities offered hereby to any accounts over which it has discretionary authority.

Pursuant to “lock-up” agreements, we, all of our executive officers and directors and certain of our affiliates, have agreed, subject to certain exceptions, without the prior written consent of the Representative not to directly or indirectly, offer to sell, sell, pledge or otherwise transfer or dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the transfer or disposition by any person at any time in the future of) any of our units, enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of our securities, make any demand for or exercise any right or cause to be filed a registration statement, including any amendments thereto, with respect to the registration of any common shares or securities convertible into or exercisable or exchangeable for common shares or any other securities of our Company or publicly disclose the intention to do any of the foregoing, subject to certain exceptions, for a period of 120 days from the closing of this offering.

Within four months following either the expiration of our engagement of the Representative or the consummation of the offering, if we complete any financing of equity, equity-linked, convertible or debt or other capital raising activity (other than the exercise by any person or entity of any options, warrants or other convertible securities issued in the offering and with certain other exceptions) with any of the investors that have participated in the offering (excluding any investors that held any of our securities prior to the expiration of the engagement or the closing of the offering, or were not introduced to us by the Representative), the Representative will be entitled to compensation as set forth in this section.

A prospectus in electronic format may be made available on the websites maintained by one or more of the underwriters or selling group members. The Representative may agree to allocate a number of securities to the underwriters and selling group members for sale to its online brokerage account holders. Internet distributions will be allocated by the underwriter and selling group members that will make internet distributions on the same basis as other allocations. Other than the prospectus in electronic format, the information on these websites is not part of, nor incorporated by reference into, this prospectus or the registration statement of which this prospectus forms a part, has not been approved or endorsed by us, and should not be relied upon by investors.

In connection with this offering, the underwriters may engage in stabilizing transactions, over-allotment transactions, syndicate-covering transactions, penalty bids and purchases to cover positions created by short sales.

These stabilizing transactions, over-allotment transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of our securities or preventing or retarding a decline in the market price of our securities. As a result, the price of our securities in the open market may be higher than it would otherwise be in the absence of these transactions. Neither we nor the underwriters make any representation or prediction as to the effect that the transactions described above may have on the price of our securities. These transactions may be effected on the Nasdaq Capital Market, in the over-the-counter market or otherwise and, if commenced, may be discontinued at any time.

In connection with this offering, the underwriters and selling group members may engage in passive market making transactions in our securities in accordance with Rule 103 of Regulation M under the Exchange Act, during a period before the commencement of offers or sales of the shares and extending through the completion of the distribution. In general, a passive market maker must display its bid at a price not in excess of the highest independent bid of that security. However, if all independent bids are lowered below the passive market maker’s bid, then that bid must then be lowered when specified purchase limits are exceeded.

This prospectus constitutes an “exempt offering document” as defined in and for the purposes of applicable Canadian securities laws. No prospectus has been filed with any securities commission or similar regulatory authority in Canada in connection with the offer and sale of the securities. No securities commission or similar regulatory authority in Canada has reviewed or in any way passed upon this prospectus or on the merits of the securities and any representation to the contrary is an offence.

Canadian investors are advised that this prospectus has been prepared in reliance on section 3A.3 of National Instrument 33-105 Underwriting Conflicts (“NI 33-105”). Pursuant to section 3A.3 of NI 33-105, this prospectus is exempt from the requirement that the Company and the underwriter(s) provide Canadian investors with certain conflicts of interest disclosure pertaining to “connected issuer” and/or “related issuer” relationships that may exist between the Company and the underwriter(s) as would otherwise be required pursuant to subsection 2.1(1) of NI 33-105.

The offer and sale of the securities in Canada is being made on a private placement basis only and is exempt from the requirement that the Company prepares and files a prospectus under applicable Canadian securities laws. Any resale of securities acquired by a Canadian investor in this offering must be made in accordance with applicable Canadian securities laws, which may vary depending on the relevant jurisdiction, and which may require resales to be made in accordance with Canadian prospectus requirements, pursuant to a statutory exemption from the prospectus requirements, in a transaction exempt from the prospectus requirements or otherwise under a discretionary exemption from the prospectus requirements granted by the applicable local Canadian securities regulatory authority. These resale restrictions may under certain circumstances apply to resales of the securities outside of Canada.

Each Canadian investor who purchases securities will be deemed to have represented to the Company, the underwriters and to each dealer from whom a purchase confirmation is received, as applicable, that the investor is (i) purchasing as principal, or is deemed to be purchasing as principal in accordance with applicable Canadian securities laws, for investment only and not with a view to resale or redistribution; (ii) an “accredited investor” as such term is defined in section 1.1 of National Instrument 45-106 Prospectus Exemptions or, in Ontario, as such term is defined in section 73.3(1) of the Securities Act (Ontario); and (iii) is a “permitted client” as such term is defined in section 1.1 of National Instrument 31-103 Registration Requirements, Exemptions and Ongoing Registrant Obligations.

Any discussion of taxation and related matters contained in this prospectus does not purport to be a comprehensive description of all of the tax considerations that may be relevant to a Canadian investor when deciding to purchase the securities and, in particular, does not address any Canadian tax considerations. No representation or warranty is hereby made as to the tax consequences to a resident, or deemed resident, of Canada of an investment in the securities or with respect to the eligibility of the securities for investment by such investor under relevant Canadian federal and provincial legislation and regulations.

Securities legislation in certain of the Canadian jurisdictions provides certain purchasers of securities pursuant to an offering memorandum (such as this prospectus), including where the distribution involves an “eligible foreign security” as such term is defined in Ontario Securities Commission Rule 45-501 Ontario Prospectus and Registration Exemptions and in Multilateral Instrument 45-107 Listing Representation and Statutory Rights of Action Disclosure Exemptions, as applicable, with a remedy for damages or rescission, or both, in addition to any other rights they may have at law, where the offering memorandum, or other offering document that constitutes an offering memorandum, and any amendment thereto, contains a “misrepresentation” as defined under applicable Canadian securities laws. These remedies, or notice with respect to these remedies, must be exercised or delivered, as the case may be, by the purchaser within the time limits prescribed under, and are subject to limitations and defenses under, applicable Canadian securities legislation. In addition, these remedies are in addition to and without derogation from any other right or remedy available at law to the investor.

Upon receipt of this document, each Canadian investor hereby confirms that it has expressly requested that all documents evidencing or relating in any way to the sale of the securities described herein (including for greater certainty any purchase confirmation or any notice) be drawn up in the English language only. Par la réception de ce document, chaque investisseur canadien confirme par les présentes qu’il a expressément exigé que tous les documents faisant foi ou se rapportant de quelque manière que ce soit à la vente des valeurs mobilières décrites aux présentes (incluant, pour plus de certitude, toute confirmation d’achat ou tout avis) soient rédigés en anglais seulement.

As required by the Securities Act of 1933, as amended, we filed a registration statement relating to the securities offered by this prospectus supplement and its accompanying prospectus with the Commission. This prospectus supplement and its accompanying prospectus are a part of that registration statement, which includes additional information.

We file annual and other reports with the Commission. You may read and copy any document that we file and obtain copies at prescribed rates from the Commission’s Public Reference Room at 100 F Street, N.E., Washington, D.C. 20549. You may obtain information on the operation of the Public Reference Room by calling 1 (800) SEC-0330. The Commission maintains a website (http://www.sec.gov) that contains reports, proxy and information statements and other information regarding issuers that file electronically with the Commission. Further information about our company is available on our website at http://www.seanergymaritime.com. The information on our website, however, is not, and should not be, deemed to be a part of this prospectus supplement.

The Commission allows us to “incorporate by reference” information that we file with it. This means that we can disclose important information to you by referring you to those filed documents. The information incorporated by reference is considered to be a part of this prospectus supplement and accompanying prospectus,

and information that we file later with the Commission prior to the termination of this offering will also be considered to be part of this prospectus supplement and the accompanying prospectus and will automatically update and supersede previously filed information, including information contained in this prospectus supplement and the accompanying prospectus.

We incorporate by reference the documents listed below:

We are also incorporating by reference all subsequent annual reports on Form 20-F that we file with the Commission and reports on Form 6-K that we furnish to the Commission after the date of this prospectus supplement that state they are incorporated by reference into this prospectus supplement until we file a post-effective amendment indicating that the offering of the securities made by this prospectus supplement has been terminated. In all cases, you should rely on the later information over different information included in this prospectus supplement or the accompanying prospectus.

You should rely only on the information contained in or incorporated by reference in this prospectus supplement, the accompanying prospectus and any free writing prospectus. We have not authorized anyone to provide you with information that is different. If anyone provides you with different or inconsistent information, you should not rely on it. We are offering to sell our securities only in jurisdictions where offers and sales are permitted. The information contained in or incorporated by reference in this document is accurate only as of the date such information was issued, regardless of the time of delivery of this prospectus supplement or any sale of our securities.

You may request a free copy of the above mentioned filings or any subsequent filing we incorporate by reference into this prospectus supplement by contacting us at the following address:

We will furnish holders of our common shares with annual reports containing audited financial statements and a report by our independent registered public accounting firm. The audited financial statements will be prepared in accordance with U.S. generally accepted accounting principles. As a “foreign private issuer”, we are exempt from the rules under the Securities and Exchange Act of 1934, as amended, or the Exchange Act, prescribing the furnishing and content of proxy statements to shareholders. While we furnish proxy statements to shareholders in accordance with the rules of Nasdaq, those proxy statements do not conform to Schedule 14A of the proxy rules promulgated under the Exchange Act. In addition, as a “foreign private issuer”, our officers and directors are exempt from the rules under the Exchange Act relating to short swing profit reporting and liability.

Through this prospectus we may periodically offer:

We may also offer securities of the types listed above that are convertible or exchangeable into one or more of the securities listed above.

The aggregate offering price of all securities issued under this prospectus may not exceed $200,000,000. The securities issued under this prospectus may be offered directly or through underwriters, agents or dealers. The names of any underwriters, agents or dealers will be included in a supplement to this prospectus.

The prices and other terms of the securities that we will offer will be determined at the time of their offering and will be described in a supplement to this prospectus.

Our common shares and class A warrants trade on the Nasdaq Capital Market under the symbols “SHIP” and “SHIPW”, respectively.

The aggregate market value of our outstanding common stock held by non-affiliates is $20,033,548, based on 38,193,348 shares of common stock outstanding, of which 20,235,907 are held by non-affiliates, and a closing price on the Nasdaq Capital Market of $0.99 on August 9, 2018. As of the date hereof, we have not offered any securities pursuant to General Instruction I.B.5 of Form F-3 during the twelve calendar month period that ends on and includes the date hereof.

An investment in these securities involves risks. See the section entitled “Risk Factors” beginning on page 3 of this prospectus, and other risk factors contained in the applicable prospectus supplement and in the documents incorporated by reference herein and therein.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

This prospectus is part of a registration statement that we filed with the U.S. Securities and Exchange Commission, or the SEC, using a shelf registration process. Under the shelf registration process, we may sell shares of common stock, shares of preferred stock, debt securities, warrants, purchase contracts, rights and units described in this prospectus from time to time in one or more offerings, up to a total of $200,000,000. This prospectus only provides you with a general description of the securities we may offer. Each time we offer securities, we will provide you with a supplement to this prospectus that will describe the specific information about the securities being offered and the specific terms of that offering. The supplement may also add, update or change the information contained in this prospectus. If there is any inconsistency between the information in this prospectus and any prospectus supplement, you should rely on the prospectus supplement. Before purchasing any securities, you should read carefully both this prospectus and any supplement, together with the additional information described below.

This prospectus and any prospectus supplement are part of a registration statement we filed with the SEC and do not contain all the information in the registration statement. Forms of the indenture and other documents establishing the terms of the offered securities are filed as exhibits to the registration statement. Statements in this prospectus or any prospectus supplement about these documents are summaries and each statement is qualified in all respects by reference to the document to which it refers. You should refer to the actual documents for a more complete description of the relevant matters. For further information about us or the securities offered hereby, you should refer to the registration statement, which you can obtain from the SEC as described below under the section entitled “Where You Can Find Additional Information”.

You should rely only on the information contained or incorporated by reference in this prospectus and in any prospectus supplement. We have not authorized any other person to provide you with different information. If anyone provides you with different or inconsistent information, you should not rely on it. We will not make an offer to sell these securities in any jurisdiction where the offer or sale is not permitted. You should assume that the information appearing in this prospectus and the applicable supplement to this prospectus is accurate as of the date on its respective cover, and that any information incorporated by reference is accurate only as of the date of the document incorporated by reference, unless we indicate otherwise. Our business, financial condition, results of operations and prospects may have changed since those dates.

An investment in our securities involves a high degree of risk and uncertainty. You should carefully consider the risks discussed under the caption “Risk Factors” in our Annual Report on Form 20-F for the year ended December 31, 2017, and incorporated by reference herein, as well as the other information included in this prospectus and the other documents we have incorporated by reference in this prospectus, including the section entitled “Risk Factors” in future Annual Reports before deciding to invest in our securities. In addition, prospective U.S. Holders (as such term is defined in the discussion of “Taxation” in our annual report on Form 20-F for the year ended December 31, 2017) should consider the significant U.S. tax consequences relating to the ownership of our securities. Furthermore, you should also consider carefully the risks set forth under the heading “Risk Factors” in any prospectus supplement before investing in any securities offered by this prospectus. The occurrence of one or more of those risk factors could adversely impact our business, results of operations or financial condition. This prospectus also contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in the forward-looking statements as a result of the risks below.

On April 23, 2018, we received notice from the Nasdaq Stock Market, or the Nasdaq, indicating that we were no longer in compliance with Nasdaq Listing Rule 5550(a)(2) because the closing share bid price was below the minimum $1.00 per share requirement for 30 consecutive business days, from March 8, 2018 to April 20, 2018. We have 180 days, or until October 22, 2018, to regain compliance. We intend to monitor the closing bid price of our common stock between now and October 22, 2018 and are considering our options, in order to regain compliance with the Nasdaq Capital Market minimum bid price requirement. We can cure this deficiency if the closing bid price of our common stock is $1.00 per share or higher for at least ten consecutive business days during the grace period. In the event we do not regain compliance within the 180-day grace period and meet all other listing standards and requirements, we may be eligible for an additional 180-day grace period. During this time, our common stock will continue to be listed and trade on the Nasdaq Capital Market. However, if we do not regain compliance with the Nasdaq’s continued listing standards and delist from the Nasdaq and our common shares are not subsequently listed and registered on another national securities exchange, we will be unable to meet certain transaction requirements that would effectively prevent us from offering and selling additional common shares under this registration statement.

This prospectus contains certain forward-looking statements made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include, but are not limited to, statements regarding our or our management’s expectations, hopes, beliefs, intentions or strategies regarding the future and other statements that are other than statements of historical fact. In addition, any statements that refer to projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements. The words “anticipate”, “believe”, “continue”, “could”, “estimate”, “expect”, “intend”, “may”, “might”, “plan”, “possible”, “potential”, “predict”, “project”, “should”, “would” and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking.

The forward-looking statements in this report are based upon various assumptions, many of which are based, in turn, upon further assumptions, including without limitation, management’s examination of historical operating trends, data contained in our records and other data available from third parties. Although we believe that these assumptions were reasonable when made, because these assumptions are inherently subject to significant uncertainties and contingencies which are difficult or impossible to predict and are beyond our control, we cannot assure you that we will achieve or accomplish these expectations, beliefs or projections. As a result, you are cautioned not to rely on any forward-looking statements.

In addition to these important factors, important factors that, in our view, could cause actual results to differ materially from those discussed in the forward-looking statements include among other things:

Should one or more of the foregoing risks or uncertainties materialize, or should any of our assumptions prove incorrect, actual results may vary in material respects from those projected in these forward looking statements. Other unknown or unpredictable factors also could harm our results. Consequently, there can be no assurance that actual results or developments anticipated by us will be realized or, even if substantially realized, that they will have the expected consequences to, or effects, on us. Given these uncertainties, prospective investors are cautioned not to place undue reliance on such forward-looking statements.

We undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required under applicable laws. If one or more forward-looking statements are updated, no inference should be drawn that additional updates will be made with respect to those or other forward-looking statements.

See the section entitled “Risk Factors,” on page 3 of this prospectus and in our Annual Report on Form 20-F for the fiscal year ended December 31, 2017, and incorporated by reference herein, for a more complete discussion of these risks and uncertainties and for other risks and uncertainties. These factors and the other risk factors described in this prospectus are not necessarily all of the important factors that could cause actual results or developments to differ materially from those expressed in any of our forward-looking statements. Other unknown or unpredictable factors also could harm our results. Consequently, there can be no assurance that actual results or developments anticipated by us will be realized or, even if substantially realized, that they will have the expected consequences to, or effects on, us. Given these uncertainties, prospective investors are cautioned not to place undue reliance on such forward-looking statements.

The following table sets forth our unaudited ratio of earnings to fixed charges for each of the years ended December 31, 2017, 2016, 2015, 2014 and 2013 and for the six months period ended June 30, 2018.⁽¹⁾

In addition, we may enter into options or other types of transactions that require us to deliver our securities to a broker-dealer, who will then resell or transfer the securities under this prospectus. We may enter into hedging transactions with respect to our securities. For example, we may:

We may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and, if not identified in this prospectus, will be identified in the applicable prospectus supplement (or a post-effective amendment). In addition, we may otherwise loan or pledge securities to a financial institution or other third party that in turn may sell the securities short using this prospectus. Such financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.

Any broker-dealers or other persons acting on our behalf that participate with us in the distribution of the securities may be deemed to be underwriters and any commissions received or profit realized by them on the resale of the securities may be deemed to be underwriting discounts and commissions under the Securities Act of 1933, as amended, or the Securities Act. As of the date of this prospectus, we are not a party to any agreement, arrangement or understanding between any broker or dealer and us with respect to the offer or sale of the securities pursuant to this prospectus.

At the time that any particular offering of securities is made, to the extent required by the Securities Act, a prospectus supplement will be distributed, setting forth the terms of the offering, including the aggregate number of securities being offered, the purchase price of the securities, the initial offering price of the securities, the names of any underwriters, dealers or agents, any discounts, commissions and other items constituting compensation from us and any discounts, commissions or concessions allowed or reallowed or paid to dealers. Furthermore, we, our executive officers, our directors and major shareholders may agree, subject to certain exemptions, that for a certain period from the date of the prospectus supplement under which the securities are offered, we and they will not, without the prior written consent of an underwriter, offer, sell, contract to sell, pledge or otherwise dispose of any of our common shares or any securities convertible into or exchangeable for

common shares. However, an underwriter, in its sole discretion, may release any of the securities subject to these lock-up agreements at any time without notice. We expect an underwriter to exclude from these lock-up agreements securities exercised and/or sold pursuant to trading plans entered into by us pursuant to Rule 10b5-1 under the Exchange Act, that are in place at the time of an offering pursuant to this prospectus and any applicable prospectus supplement hereto that provide for periodic sales of our securities on the basis of parameters described in such trading plans.

Underwriters or agents could make sales in privately negotiated transactions and/or any other method permitted by law, including sales deemed to be an at-the-market offering as defined in Rule 415 promulgated under the Securities Act, which includes sales made directly on or through the Nasdaq Capital Market, the existing trading market for our shares of common stock, or sales made to or through a market maker other than on an exchange.

We will bear costs relating to all of the securities offered and sold by us under this registration statement.

We are a Marshall Islands company, and our principal executive office is located outside of the United States in Greece. Some of our directors, officers and the experts named in this registration statement reside outside the United States. In addition, a substantial portion of our assets and the assets of certain of our directors, officers and experts are located outside of the United States. As a result, it may be difficult or impossible for U.S. investors to serve process within the United States upon us or any of these persons. You may also have difficulty enforcing, both in and outside the United States, judgments you may obtain in United States courts against us or these persons in any action, including actions based upon the civil liability provisions of United States federal or state securities laws.

Furthermore, there is substantial doubt that courts in the countries in which we or our subsidiaries are incorporated or where our assets or the assets of our subsidiaries, directors or officers and such experts are located (i) would enforce judgments of U.S. courts obtained in actions against us or our subsidiaries, directors or officers and such experts based upon the civil liability provisions of applicable U.S. federal and state securities laws or (ii) would enforce, in original actions, liabilities against us or our subsidiaries, directors or officers and such experts based on those laws.

For the complete terms of our capital stock, please refer to our amended and restated articles of incorporation and our second amended and restated bylaws, which are filed as exhibits to the registration statement of which this prospectus forms a part. The Business Corporation Act of the Republic of the Marshall Islands, or the BCA, may also affect the terms of our capital stock.

For purposes of the following description of capital stock, references to “us”, “we” and “our” refer only to Seanergy Maritime Holdings Corp. and not any of its subsidiaries.

Our purpose, as stated in our amended and restated articles of incorporation, is to engage in any lawful act or activity for which corporations may now or hereafter be organized under the BCA. Our amended and restated articles of incorporation and bylaws do not impose any limitations on the ownership rights of our shareholders.

Our authorized capital stock consists of 500,000,000 registered common shares, par value $0.0001 per share, of which 38,193,348 shares were issued and outstanding as of the date of this prospectus, and 25,000,000 registered preferred shares with par value of $0.0001, of which no shares are issued and outstanding. Our board of directors has the authority to establish such series of preferred stock and with such designations, preferences and relative, participating, optional or special rights and qualifications, limitations or restrictions as shall be stated in the resolution or resolutions providing for the issue of such preferred stock.

We were incorporated under the laws of the Republic of the Marshall Islands on January 4, 2008, originally under the name Seanergy Merger Corp., as a wholly-owned subsidiary of Seanergy Maritime Corp. We changed our name to Seanergy Maritime Holdings Corp. on July 11, 2008. Seanergy Maritime Corp.’s shares of common stock were originally listed on the American Stock Exchange. On October 15, 2008, Seanergy Maritime Corp.’s shares of common stock commenced trading on the Nasdaq Global Market. Following the dissolution of Seanergy Maritime Corp., our shares of common stock started trading on the Nasdaq Global Market on January 28, 2009. Effective December 21, 2012, we transferred our stock listing to the Nasdaq Capital Market. The following information gives effect to a one-for-five reverse stock split of our common shares that became effective on January 8, 2016.

On January 31, 2012, we completed an equity injection plan with four entities affiliated with the Restis family. In exchange for $10 million, we issued an aggregate of 928,324 of our common shares to the four entities at a price of $10.7721 per share.

On June 24, 2014, we entered into a share purchase agreement with Plaza Shipholding Corp., or Plaza, and Comet Shipholding Inc., or Comet, which are both companies affiliated with our Sponsor’s family, under which we sold 378,000 of our common shares for $1.134 million, equal to a price per share of $3.00, and on the same date we entered into a registration rights agreement in connection with such share purchase.

On September 29, 2014, we entered into a share purchase agreement with Plaza and Comet, under which we sold 320,000 of our common shares for $0.96 million, equal to a price per share of $3.00, and on the same date we entered into a registration rights agreement in connection with such share purchase.

On the same date, we entered into registration rights agreements with Jelco and our Chief Executive Officer with respect to these common shares.

On September 7, 2015, we entered into a share purchase agreement with Jelco, under which we sold 10,022,240 of our common shares in three tranches to Jelco for $9.0 million or $0.90 per share. On the same date, we entered into registration rights agreement with Jelco with respect to these common shares.

On August 5, 2016, we sold 1,180,000 of our common shares in a registered direct offering to an unaffiliated institutional investor at a public offering price of $4.15 per share.

On November 23, 2016, we sold 1,305,000 of our common shares in a registered direct offering to unaffiliated institutional investors at a public offering price of $2.75 per share.

On December 13, 2016, we sold 10,000,000 of our common shares and Class A Warrants to purchase 10,000,000 of our common shares in a registered public offering at a combined public offering price of $1.50 per share and warrant. In connection with the sale of the securities, we issued to the representative of the underwriters a Representative’s Warrant to purchase 500,000 of our common shares.

In connection with the sale of the securities, we issued to the representative of the underwriters a Representative’s Warrant to purchase 65,000 of our common shares.

On April 10, 2017, we issued 125,000 of our common shares in a private placement to a third-party service provider as compensation.

Under our second amended and restated bylaws, annual shareholder meetings will be held at a time and place selected by our board of directors. The meetings may be held in or outside of the Marshall Islands. Special meetings of the shareholders, unless otherwise prescribed by law, may be called for any purpose or purposes at any time exclusively by the board of directors. Notice of every annual and special meeting of shareholders shall be given at least 15 but not more than 60 days before such meeting to each shareholder of record entitled to vote thereat.

Our directors are elected by the affirmative vote of a plurality of the votes cast at a meeting of the shareholders by the holders of shares entitled to vote in the election. Our amended and restated articles of incorporation and second amended and restated bylaws prohibit cumulative voting in the election of directors.

The board of directors must consist of at least one member and not more than thirteen. Each director shall be elected to serve until the third succeeding annual meeting of shareholders and until his successor shall have been duly elected and qualified, except in the event of his death, resignation, removal, or the earlier termination of his term of office. The board of directors has the authority to fix the amounts which shall be payable to the members of our board of directors, and to members of any committee, for attendance at any meeting or for services rendered to us.

Our amended and restated articles of incorporation provide for the division of our board of directors into three classes of directors, with each class as nearly equal in number as possible, serving staggered, three-year terms. Approximately one-third of our board of directors will be elected each year. This classified board provision could discourage a third party from making a tender offer for our shares or attempting to obtain control of our company. It could also delay shareholders who do not agree with the policies of the board of directors from removing a majority of the board of directors for two years.

Our amended and restated articles of incorporation and second amended and restated bylaws require parties other than the board of directors to give advance written notice of nominations for the election of directors.

Our second amended and restated bylaws provide that our directors may be removed only for cause and only upon the affirmative vote of the majority of the outstanding shares of our capital stock entitled to vote for those directors. These provisions may discourage, delay or prevent the removal of incumbent officers and directors.

Under the BCA, our shareholders generally have the right to dissent from the sale of all or substantially all of our assets not made in the usual course of our business and receive payment of the fair value of their shares. However, the right of a dissenting shareholder to receive payment of the appraised fair value of his shares is not available under the BCA for the shares of any class or series of stock, which shares at the record date fixed to determine the shareholders entitled to receive notice of and to vote at the meeting of the shareholders to act upon the agreement of merger or consolidation, were either (i) listed on a securities exchange or admitted for trading on an interdealer quotation system or (ii) held of record by more than 2,000 holders. In the event of any further amendment of our articles of incorporation, a shareholder also has the right to dissent and receive payment for his or her shares if the amendment alters certain rights in respect of those shares. The dissenting shareholder must follow the procedures set forth in the BCA to receive payment.

Under the BCA, any of our shareholders may bring an action in our name to procure a judgment in our favor, also known as a derivative action, provided that the shareholder bringing the action is a holder of common shares both at the time the derivative action is commenced and at the time of the transaction to which the action relates.

Several provisions of our amended and restated articles of incorporation and second amended and restated bylaws may have anti-takeover effects. These provisions are intended to avoid costly takeover battles, lessen our vulnerability to a hostile change of control and enhance the ability of our board of directors to maximize shareholder value in connection with any unsolicited offer to acquire us. However, these anti-takeover provisions, which are summarized below, could also discourage, delay or prevent (1) the merger or acquisition of our company by means of a tender offer, a proxy contest or otherwise, that a shareholder may consider in its best interest and (2) the removal of incumbent officers and directors.

Our amended and restated articles of incorporation and second amended and restated bylaws provide that any action required or permitted to be taken by our shareholders must be effected at an annual or special meeting of our shareholders or by the unanimous written consent of our shareholders.

Our amended and restated articles of incorporation and second amended and restated bylaws provide that only our board of directors may call special meetings of our shareholders and the business transacted at the special meeting is limited to the purposes stated in the notice. Accordingly, a shareholder may be prevented from calling a special meeting for shareholders’ consideration of a proposal over the opposition of our board of directors and shareholders’ consideration of a proposal may be delayed until the next annual meeting.

Under the terms of our amended and restated articles of incorporation, our board of directors has authority, without any further vote or action by our shareholders, to issue up to 25,000,000 shares of blank check preferred stock. Our board of directors may issue shares of preferred stock on terms calculated to discourage, delay or prevent a change of control of our company or the removal of our management.

The registrar and transfer agent for our common shares is Continental Stock Transfer & Trust Company.

Our common shares trade on the Nasdaq Capital Market under the symbol “SHIP”.

We may issue debt securities from time to time in one or more series, under one or more indentures, each dated as of a date on or prior to the issuance of the debt securities to which it relates, and pursuant to an applicable prospectus supplement. We may issue senior debt securities and subordinated debt securities pursuant to separate indentures, a senior indenture and a subordinated indenture, respectively, in each case between us and the trustee named in the indenture. These indentures will be filed either as exhibits to an amendment to the registration statement of which this prospectus forms a part or as an exhibit to a report under the Exchange Act, that will be incorporated by reference into the registration statement of which this prospectus forms a part or a prospectus supplement. We refer to any applicable prospectus supplement, amendment to the registration statement and/or Exchange Act report as “subsequent filings”. The senior indenture and the subordinated indenture, as amended or supplemented from time to time, are each referred to individually as an “indenture” and collectively as the “indentures”. Each indenture will be subject to and governed by the Trust Indenture Act of 1939, as amended, and will be construed in accordance with and governed by the laws of the State of New York (without giving effect to any principles thereof relating to conflicts of law that would result in the application of the laws of any other jurisdiction) unless otherwise stated in the applicable prospectus supplement and indenture (or post-effective amendment hereto). Each indenture will contain the specific terms of any series of debt securities or provide that those terms must be set forth in or determined pursuant to, an authorizing resolution, as defined in the applicable prospectus supplement or a supplemental indenture, if any, relating to such series.

The following description sets forth certain general terms and provisions of the debt securities. The particular terms and provisions of the debt securities offered by any prospectus supplement, and the extent to which the general terms and provisions described below may apply to the offered debt securities, will be described in the applicable subsequent filings. The statements below are not complete and are subject to, and are qualified in their entirety by reference to, all of the provisions of the applicable indenture. The specific terms of any debt securities that we may offer, including any modifications of, or additions to, the general terms described below as well as any applicable material U.S. federal income tax considerations concerning the ownership of such debt securities will be described in the applicable prospectus supplement and indenture and, as applicable, supplemental indenture. Accordingly, for a complete description of the terms of a particular issue of debt securities, the general description of the debt securities set forth below should be read in conjunction with the applicable prospectus supplement and indenture, as amended or supplemented from time to time.

We expect that neither indenture will limit the amount of debt securities which may be issued and that each indenture will provide that debt securities may be issued in one or more series.

We expect that the subsequent filings related to a series of offered debt securities will describe the following terms of the series:

Subsequent filings may include additional terms not listed above. Unless otherwise indicated in subsequent filings with the SEC relating to the indenture, principal, premium and interest will be payable and the debt securities will be transferable at the corporate trust office of the applicable trustee. Unless other arrangements are made or set forth in subsequent filings or a supplemental indenture, principal, premium and interest will be paid by checks mailed to the registered holders at their registered addresses.

Unless otherwise indicated in subsequent filings with the SEC, the debt securities will be issued only in fully registered form without coupons, in denominations of $1,000 or any integral multiple thereof. No service charge will be made for any transfer or exchange of the debt securities, but we may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection with these debt securities.

Some or all of the debt securities may be issued as discounted debt securities, bearing no interest or interest at a rate which at the time of issuance is below market rates, to be sold at a substantial discount below the stated principal amount. United States federal income tax consequences and other special considerations applicable to any discounted securities will be described in subsequent filings with the SEC relating to those securities.

We refer you to the applicable subsequent filings for the particular terms and provisions of the debt securities offered by any prospectus supplement.

We may issue senior debt securities under a senior debt indenture. These senior debt securities would rank on an equal basis with all our other unsubordinated debt.

We may issue subordinated debt securities under a subordinated debt indenture. These subordinated debt securities would rank subordinate and junior in priority of payment to certain of our other indebtedness to the extent described in the applicable prospectus supplement.

Any series of offered debt securities may have covenants in addition to or differing from those included in the applicable indenture which will be described in subsequent filings prepared in connection with the offering of such securities, limiting or restricting, among other things:

We expect that each indenture and the rights of the respective holders generally may be modified by us only with the consent of holders of not less than a majority in aggregate principal amount of the outstanding debt securities of all series under the respective indenture affected by the modification, taken together as a class. But we expect that no modification that:

Additionally, certain changes under each indenture will not require the consent of any holders. These types of changes are generally limited to clarifications of ambiguities, omissions, defects and inconsistencies in each

indenture and amendments, supplements and other changes that would not adversely affect the holders of outstanding debt securities under each indenture, such as adding security, covenants, additional events of default or successor trustees.

We expect that each indenture will define an event of default for the debt securities of any series as being any one of the following events:

An event of default of one series of debt securities will not necessarily constitute an event of default with respect to any other series of debt securities.

There may be such other or different events of default as described in an applicable subsequent filing with respect to any class or series of offered debt securities.

We expect that under each indenture, in case an event of default occurs and continues for the debt securities of any series, the applicable trustee or the holders of not less than 25% in aggregate principal amount of the debt securities then outstanding of that series may declare the principal and accrued but unpaid interest of the debt securities of that series to be due and payable. Further, any event of default for the debt securities of any series which has been cured is expected to be permitted to be waived by the holders of a majority in aggregate principal amount of the debt securities of that series then outstanding.

We expect that each indenture will require us to file annually, after debt securities are issued under that indenture, with the applicable trustee a written statement signed by two of our officers as to the absence of material defaults under the terms of that indenture. We also expect that each indenture will provide that the applicable trustee may withhold notice to the holders of any default if it considers it in the interest of the holders to do so, except notice of a default in payment of principal, premium or interest.

Subject to the duties of the trustee in case an event of default occurs and continues, we expect that each indenture will provide that the trustee is under no obligation to exercise any of its rights or powers under that indenture at the request, order or direction of holders unless the holders have offered to the trustee reasonable indemnity. Subject to these provisions for indemnification and the rights of the trustee, each indenture is expected to provide that the holders of a majority in principal amount of the debt securities of any series then outstanding have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee as long as the exercise of that right does not conflict with any law or the indenture.

The terms of each indenture are expected to provide us with the option to be discharged from any and all obligations in respect of the debt securities issued thereunder upon the deposit with the trustee, in trust, of money or U.S. government obligations, or both, which through the payment of interest and principal will provide money in an amount sufficient to pay any installment of principal, premium and interest on, and any mandatory sinking

fund payments in respect of, the debt securities on the stated maturity of the payments in accordance with the terms of the debt securities and the indenture governing the debt securities.

We expect that this right may only be exercised if, among other things, we have received from, or there has been published by, the United States Internal Revenue Service a ruling to the effect that such a discharge will not be deemed, or result in, a taxable event with respect to holders. This discharge would not apply to our obligations to register the transfer or exchange of debt securities, to replace stolen, lost or mutilated debt securities, to maintain paying agencies and hold moneys for payment in trust.

We expect that the terms of each indenture will provide us with the right to omit complying with specified covenants and specified events of default described in a subsequent filing upon the deposit with the trustee, in trust, of money or U.S. government obligations, or both, which through the payment of interest and principal will provide money in an amount sufficient to pay any installment of principal, premium and interest on, and any mandatory sinking fund payments in respect of, the debt securities on the stated maturity of the payments in accordance with the terms of the debt securities and the indenture governing the debt securities.

We expect that to exercise this right we will also be required to deliver to the trustee an opinion of counsel to the effect that we have received from, or there has been published by, the United States Internal Revenue Service a ruling to the effect that the deposit and related covenant defeasance will not cause the holders of such series to recognize income, gain or loss for United States federal income tax purposes.

A subsequent filing may further describe the provisions, if any, of any particular series of offered debt securities permitting a discharge defeasance.

Each debt security will be represented either by a certificate issued in definitive form to a particular investor or by one or more global securities representing the entire issuance of securities. Both certificated securities in definitive form and global securities may be issued either in registered form, where our obligation runs to the holder of the security named on the face of the security, or in bearer form, where our obligation runs to the bearer of the security.

Definitive securities name you or your nominee as the owner of the security, other than definitive bearer securities, which name the bearer as owner, and in order to transfer or exchange these securities or to receive payments other than interest or other interim payments, you or your nominee must physically deliver the securities to the trustee, registrar, paying agent or other agent, as applicable.

Global securities name a depositary or its nominee as the owner of the debt securities represented by these global securities, other than global bearer securities, which name the bearer as owner. The depositary maintains a computerized system that will reflect each investor’s beneficial ownership of the securities through an account maintained by the investor with its broker/dealer, bank, trust company or other representative, as we explain more fully below.

We may issue the debt securities in the form of one or more fully registered global securities that will be deposited with a depositary or its nominee identified in the applicable prospectus supplement and registered in the name of that depositary or nominee. In those cases, one or more registered global securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal or face amount of the securities to be represented by registered global securities. Unless and until it is exchanged in whole for securities in definitive registered form, a registered global security may not be transferred except as a whole by and among the depositary for the registered global security, the nominees of the depositary or any successors of the depositary or those nominees. If not described below, any specific terms of the depositary arrangement with respect to any debt securities to be represented by a registered global security will be described in the prospectus supplement relating to those debt securities. We anticipate that the following provisions will apply to all depositary arrangements:

Ownership of beneficial interests in a registered global security will be limited to persons, called participants, that have accounts with the depositary or persons that may hold interests through participants. Upon

the issuance of a registered global security, the depositary will credit, on its book-entry registration and transfer system, the participants’ accounts with the respective principal or face amounts of the securities beneficially owned by the participants. Any dealers, underwriters or selling agents participating in the distribution of the securities will designate the accounts to be credited. Ownership of beneficial interests in a registered global security will be shown on, and the transfer of ownership interests will be effected only through, records maintained by the depositary, with respect to interests of participants, and on the records of participants, with respect to interests of persons holding through participants. The laws of some jurisdictions may require that some purchasers of securities take physical delivery of these securities in definitive form. These laws may impair your ability to own, transfer or pledge beneficial interests in registered global securities. So long as the depositary, or its nominee, is the registered owner of a registered global security, that depositary or its nominee, as the case may be, will be considered the sole owner or holder of the securities represented by the registered global security for all purposes under the indenture.

Except as described below, owners of beneficial interests in a registered global security will not be entitled to have the securities represented by the registered global security registered in their names, will not receive or be entitled to receive physical delivery of the securities in definitive form and will not be considered the owners or holders of the securities under the indenture. Accordingly, each person owning a beneficial interest in a registered global security must rely on the procedures of the depositary for that registered global security and, if that person is not a participant, on the procedures of the participant through which the person owns its interest in that registered global security, to exercise any rights of a holder under the indenture. We understand that under existing industry practices, if we request any action of holders of a registered global security or if an owner of a beneficial interest in a registered global security desires to give or take any action that a holder is entitled to give or take under the indenture, the depositary for the registered global security would authorize the participants holding the relevant beneficial interests to give or take that action, and the participants would authorize beneficial owners owning through them to give or take that action or would otherwise act upon the instructions of beneficial owners holding through them.

Principal, premium, if any, and interest payments on debt securities represented by a registered global security registered in the name of a depositary or its nominee will be made to the depositary or its nominee, as the case may be, as the registered owner of the registered global security. None of us, the trustee or any other agent of us or agent of the trustee will have any responsibility or liability to owners of beneficial interests for any aspect of the records relating to payments made on account of beneficial ownership interests in the registered global security or for maintaining, supervising or reviewing any records relating to those beneficial ownership interests. We expect that the depositary for any of the securities represented by a registered global security, upon receipt of any payment of principal, premium, interest or other distribution of underlying securities or other property to holders on that registered global security, will immediately credit participants’ accounts in amounts proportionate to their respective beneficial interests in that registered global security as shown on the records of the depositary. We also expect that payments by participants to owners of beneficial interests in a registered global security held through participants will be governed by standing customer instructions and customary practices, as is now the case with the securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of those participants.

We expect that the indenture will provide that if the depositary for any of these securities represented by a registered global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Exchange Act, and a successor depositary registered as a clearing agency under the Exchange Act is not appointed by us within 90 days, we will be required to issue securities in definitive form in exchange for the registered global security that had been held by the depositary. In addition, the indenture is expected to allow us to decide, at any time and in our sole discretion, to not have any of the securities represented by one or more registered global securities. If we make that decision, we will issue securities in definitive form in exchange for all of the registered global security or securities representing those securities. Any securities issued in definitive form in exchange for a registered global security will be registered in the name or names that the depositary gives to the relevant trustee or other relevant agent of ours or theirs. It is expected that the depositary’s instructions will be based upon directions received by the depositary from participants with respect to ownership of beneficial interests in the registered global security that had been held by the depositary.

If we issue registered global securities, we expect that the Depository Trust Company, or DTC, will act as depository and the securities will be registered in the name of Cede & Co., as DTC’s nominee.

We may issue warrants to purchase our debt or equity securities or securities of third parties or other rights, including rights to receive payment in cash or securities based on the value, rate or price of one or more specified currencies, securities or indices, or any combination of the foregoing. Warrants may be issued independently or together with any other securities and may be attached to, or separate from, such securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a warrant agent. The terms of any warrants to be issued and a description of the material provisions of the applicable warrant agreement will be set forth in the applicable prospectus supplement. We expect that such terms will include, among others:

We may issue purchase contracts for the purchase or sale of:

Each purchase contract will entitle the holder thereof to purchase or sell, and obligate us to sell or purchase, on specified dates, such securities or currencies at a specified purchase price, which may be based on a formula, all as set forth in the applicable prospectus supplement. We may, however, satisfy our obligations, if any, with respect to any purchase contract by delivering the cash value of such purchase contract or the cash value of the property otherwise deliverable or, in the case of purchase contracts on underlying currencies, by delivering the underlying currencies, as set forth in the applicable prospectus supplement. The applicable prospectus supplement will also specify the methods by which the holders may purchase or sell such securities or currencies and any acceleration, cancellation or termination provisions, provisions relating to U.S. federal income tax considerations, if any, or other provisions relating to the settlement of a purchase contract.

The purchase contracts may require us to make periodic payments to the holders thereof or vice versa, which payments may be deferred to the extent set forth in the applicable prospectus supplement, and those payments may be unsecured or pre-funded on some basis. The purchase contracts may require the holders thereof to secure their obligations in a specified manner to be described in the applicable prospectus supplement. Alternatively, purchase contracts may require holders to satisfy their obligations thereunder when the purchase contracts are issued.

These rights may be issued independently or together with any other security offered by this prospectus and may or may not be transferable by the stockholder receiving the rights in the rights offering.

As required by the Securities Act of 1933, we filed a registration statement relating to the securities offered by this prospectus with the SEC. This prospectus is a part of that registration statement, which includes additional information.

We file annual and special reports with the SEC. You may read and copy any document that we file and obtain copies at prescribed rates from the SEC’s Public Reference Room at 100 F Street, N.E., Washington, D.C. 20549. You may obtain information on the operation of the Public Reference Room by calling 1 (800) SEC-0330. The SEC maintains a website (http://www.sec.gov) that contains reports, proxy and information statements and other information regarding issuers that file electronically with the SEC. Further information about our company is available on our website at http://www.seanergymaritime.com. The information on our website does not constitute a part of this prospectus.

The SEC allows us to “incorporate by reference” information that we file with it. This means that we can disclose important information to you by referring you to those filed documents. The information incorporated by reference is considered to be a part of this prospectus, and information that we file later with the SEC prior to the termination of this offering will also be considered to be part of this prospectus and will automatically update and supersede previously filed information, including information contained in this document.

We incorporate by reference the documents listed below and any future filings made with the SEC under Section 13(a), 13(c), 14 or 15(d) of the Exchange Act:

We are also incorporating by reference all subsequent annual reports on Form 20-F that we file with the SEC and certain reports on Form 6-K that we furnish to the SEC after the date of this prospectus (if they state that they are incorporated by reference into this prospectus) until we file a post-effective amendment indicating that the offering of the securities made by this prospectus has been terminated. In all cases, you should rely on the later information over different information included in this prospectus or the prospectus supplement.

You should rely only on the information contained or incorporated by reference in this prospectus and any accompanying prospectus supplement. We have not, and any underwriters have not, authorized any other person to provide you with different information. If anyone provides you with different or inconsistent information, you should not rely on it. We are not, and the underwriters are not, making an offer to sell these securities in any jurisdiction where the offer or sale is not permitted. You should assume that the information appearing in this prospectus and any accompanying prospectus supplement as well as the information we previously filed with the SEC and incorporated by reference, is accurate as of the dates on the front cover of those documents only. Our business, financial condition and results of operations and prospects may have changed since those dates.

You may request a free copy of the above mentioned filing or any subsequent filing we incorporated by reference to this prospectus by writing or telephoning us at the following address:

These reports may also be obtained on our website at www.seanergymaritime.com. None of the information on our website is a part of this prospectus.

We will furnish holders of our common shares with annual reports containing audited financial statements and a report by our independent registered public accounting firm. The audited financial statements will be prepared in accordance with U.S. GAAP. As a “foreign private issuer”, we are exempt from the rules under the Exchange Act prescribing the furnishing and content of proxy statements to shareholders. While we furnish proxy statements to shareholders in accordance with the rules of any stock exchange on which our common shares may be listed in the future, those proxy statements do not conform to Schedule 14A of the proxy rules promulgated under the Securities Exchange Act. In addition, as a “foreign private issuer”, our officers and directors are exempt from the rules under the Securities Exchange Act relating to short swing profit reporting and liability.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers or persons controlling the registrant pursuant to the foregoing provisions, the registrant has been informed that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is therefore unenforceable.
