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.

All statements in this prospectus (and in the documents incorporated by reference herein) that are not statements of historical fact are “forward-looking statements” within the meaning of the United States Private Securities Litigation Reform Act of 1995. The disclosure and analysis set forth in this prospectus includes assumptions, expectations, projections, intentions and beliefs about future events in a number of places, particularly in relation to our operations, cash flows, financial position, plans, strategies, business prospects, changes and trends in our business and the markets in which we operate. These statements are intended as “forward-looking statements”. In some cases, predictive, future-tense or forward-looking words such as “believe”, “intend”, “anticipate”, “estimate”, “project”, “forecast”, “plan”, “potential”, “may”, “should”, “could” and “expect” and similar expressions are intended to identify forward-looking statements, but are not the exclusive means of identifying such statements. In addition, we and our representatives may from time to time make other oral or written statements which are forward-looking statements, including in our periodic reports that we file with the United States Securities and Exchange Commission (“SEC”), other information sent to our security holders, and other written materials. We caution that these and other forward-looking statements included in this prospectus (and in the documents incorporated by reference herein) represent our estimates and assumptions as of the date of this prospectus (and in the documents incorporated by reference herein) or the date on which such oral or written statements are made, as applicable, about factors that are beyond our ability to control or predict, and are not intended to give any assurance as to future results.

Factors that might cause future results to differ include, but are not limited to, the following:

We undertake no obligation to update or revise any forward-looking statements contained in this prospectus, whether as a result of new information, future events, a change in our views or expectations or otherwise. New factors emerge from time to time, and it is not possible for us to predict all of these factors. Further, we cannot assess the impact of each such factor on our business or the extent to which any factor, or combination of factors, may cause actual results to be materially different from those contained in any forward-looking statement.

Unless we otherwise specify, when used in this prospectus the terms “Costamare”, the “Company”, “we”, “our”, “us” or similar terms refer to Costamare Inc. and its subsidiaries and/or any one of them. We use the term “twenty foot equivalent unit” or “TEU”, the international standard measure of containers, in describing the capacity of our containerships. We use the term deadweight ton (“dwt”) in describing the size of dry bulk vessels. Dwt, expressed in metric tons, each of which is equivalent to 1,000 kilograms, refers to the maximum weight of cargo and supplies that a vessel can carry.

We are an international owner and operator of containerships and dry bulk vessels. We charter our containerships to the world’s largest liner companies, providing worldwide transportation of containerized cargoes. We charter our dry bulk vessels to a wide variety of customers, providing worldwide transportation for dry bulk cargoes. As of March 19, 2024, our containership fleet consisted of 68 vessels in the water, aggregating approximately 513,000 TEU, making us one of the largest public containership companies in the world based on total TEU capacity. Additionally, as of the same date, our dry bulk fleet consisted of 37 vessels in the water, with a total capacity of approximately 2,539,000 dwt, including one vessel that we have agreed to sell, with a capacity of approximately 33,800 dwt. In November 2022, we established a dry bulk operating platform under Costamare Bulkers Inc., which charters-in/out dry bulk vessels, enters into contracts of affreightment, forward freight agreements and may also utilize hedging solutions. In March 2023, we agreed to invest up to $200 million in Neptune Maritime Leasing Limited (“Neptune”) and acquired the controlling interest of Neptune, which was originally established in 2021 to acquire, own and finance (via bareboat charter agreements) vessels through wholly-owned subsidiaries. Neptune’s strategy is to build a portfolio of long-term contracts through sale and leaseback transactions in the maritime sector while also utilizing bank financing.

Costamare Inc. was incorporated in the Republic of the Marshall Islands on April 21, 2008 under the BCA. We are majority owned by members of the Konstantakopoulos family, which has a long history of operating and investing in the international shipping industry, including a long history of vessel ownership. We were founded in 1974 and initially owned and operated dry bulk vessels. In 1984, we became the first Greek-owned company to enter the containership market, and from 1992 until our acquisition of dry bulk vessels in June 2021 and the subsequent expansion of our dry bulk platform in 2022, we focused exclusively on containerships. Since assuming management of our company in 1998, Konstantinos Konstantakopoulos has concentrated on building a large, modern and reliable fleet run and supported by highly skilled, experienced and loyal personnel. Under Konstantinos Konstantakopoulos’s leadership, we have continued to foster a company culture focusing on excellent customer service, industry leadership and innovation.

We maintain our principal executive offices at 7 rue du Gabian, MC 98000 Monaco. Our telephone number at that address is +377 93 25 09 40. Our registered address in the Marshall Islands is Trust Company Complex, Ajeltake Road, Ajeltake Island, Majuro, Marshall Islands MH96960. The name of our registered agent at such address is The Trust Company of the Marshall Islands, Inc.

Additional information about the Company and its subsidiaries is included in documents incorporated by reference in this prospectus. See “Incorporation of Certain Information by Reference”.

Investing in the securities to be offered pursuant to this prospectus may involve a high degree of risk. You should carefully consider the important factors set forth under the heading “Risk Factors” in our most recent Annual Report on Form 20-F filed with the SEC and incorporated herein by reference and in the accompanying prospectus supplement for such issuance before investing in any securities that may be offered. For further details, see the section entitled “Where You Can Find Additional Information”.

Any of the risk factors referred to above could significantly and negatively affect our business, results of operations or financial condition, which may reduce our ability to pay dividends and lower the trading price of our securities. The risks referred to above are not the only ones that may exist. Additional risks not currently known by us or risks that we deem immaterial may also impair our business operations. You may lose all or a part of your investment.

We are a Marshall Islands corporation and our principal executive offices are located outside of the United States in Monaco. All of our directors and officers and some of the experts in this prospectus reside outside the United States. In addition, all or a substantial portion of our assets and the assets of our directors, officers and experts are located outside of the United States. As a result, you may have difficulty serving legal process within the United States upon us or any of these persons. You may also have difficulty enforcing, both in and outside of the United States, judgments you may obtain in U.S. 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 uncertainty as to whether the courts of the Marshall Islands, Monaco or other countries where our directors may reside would enter judgments in original actions brought in those courts predicated on U.S. Federal or state securities laws.

This prospectus is part of a registration statement that we filed with the SEC using a shelf registration process. Under this shelf registration process, we may, from time to time, sell up to an aggregate public offering price of $500,000,000 of any combination of the securities described in this prospectus in one or more offerings. This prospectus provides you with a general description of the securities we may offer. Each time we sell securities, we will provide you with this prospectus, as well as a prospectus supplement or a free writing prospectus that will contain specific information about the terms of that offering. That prospectus supplement or free writing prospectus may include additional risk factors or other special considerations applicable to those particular securities. Any prospectus supplement or free writing prospectus may also add, update or change information contained in this prospectus or free writing prospectus. If there is any inconsistency between the information contained in this prospectus and any prospectus supplement or free writing prospectus, you should rely on the information contained in that particular prospectus supplement or free writing prospectus. You should read both this prospectus and any prospectus supplement or free writing prospectus together with additional information described under the heading “Where You Can Find Additional Information”.

We have filed with the SEC a registration statement on Form F-3 under the Securities Act of 1933, as amended (the “Securities Act”), with respect to the offer and sale of securities pursuant to this prospectus. This prospectus, filed as a part of the registration statement, does not contain all of the information set forth in the registration statement. The registration statement includes and incorporates by reference additional information and exhibits. Statements made in this prospectus concerning the contents of any contract, agreement or other document filed as an exhibit to the registration statement are summaries of all of the material terms of such contracts, agreements or documents, but do not repeat all of their terms. Reference is made to each such exhibit for a more complete description of the matters involved and such statements shall be deemed qualified in their entirety by such reference. The SEC maintains a website at http://www.sec.gov that contains reports, proxy and information statements and other information regarding registrants that file electronically with the SEC. For further information pertaining to the securities offered by this prospectus and Costamare Inc., reference is made to the registration statement.

We are subject to the information and periodic reporting requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and we file periodic reports and other information with the SEC. These periodic reports and other information are available for inspection and copying at the SEC’s public reference facilities and the website of the SEC referred to above. As a “foreign private issuer”, we are exempt from the rules under the Exchange Act prescribing the furnishing and content of proxy statements to stockholders, but we are required to furnish certain proxy statements to stockholders under NYSE rules. Those proxy statements are not expected to conform to Schedule 14A of the proxy rules promulgated under the Exchange Act. In addition, as a “foreign private issuer”, we are exempt from the rules under the Exchange Act relating to short swing profit reporting and liability.

The SEC allows us to “incorporate by reference” the information we file with the SEC. This means that we can disclose important information to you by referring you to another document filed separately with the SEC. The information incorporated by reference is considered to be part of this prospectus. Any information that we file later with the SEC and that is deemed incorporated by reference will also be considered to be part of this prospectus and will automatically update and supersede the information in this prospectus. In all cases, you should rely on the later information over different information included in this prospectus.

This prospectus incorporates by reference the following documents:

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 the initial registration statement filing and prior to the effectiveness of the registration statement and after the date of this prospectus (in each case, if such Form 6-K states that it is 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 any accompanying prospectus supplement or free writing prospectus.

We will provide, free of charge upon written or oral request, to each person to whom this prospectus is delivered, including any beneficial owner of the securities, a copy of any or all of the information that has been incorporated by reference into this prospectus, but which has not been delivered with the prospectus.

You should assume that the information appearing in this prospectus and any accompanying prospectus supplement or free writing prospectus, 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.

Unless otherwise set forth in the applicable prospectus supplement, we intend to use the net proceeds received from the sale of the securities we offer by this prospectus for general corporate purposes, which may include, among other things:

We may raise additional funds from time to time through equity or debt financings not involving the issuance of securities described in this prospectus, including borrowings under credit facilities, to finance our business and operations, new vessel acquisitions and other investments.

Our capitalization and indebtedness will be set forth in a prospectus supplement to this prospectus or in a report on Form 6-K subsequently furnished to the SEC and specifically incorporated herein by reference.

Our articles of incorporation authorize our board of directors to establish one or more series of preferred stock and to determine, with respect to any series of preferred stock, the terms and rights of that series. The issuance of shares of preferred stock may have the effect of discouraging, delaying or preventing a change of control of us or the removal of our management. The issuance of shares of preferred stock with voting and conversion rights may adversely affect the voting power of the holders of shares of our common stock. For those shares of preferred stock, if any, that are deposited in an American Depositary Receipt facility pursuant to a deposit agreement, to be entered into with the depositary, the depositary or its nominee is deemed the shareholder (for additional details, see “Description of American Depositary Shares”).

The applicable prospectus supplement will describe the following terms of any series of preferred shares in respect of which this prospectus is being delivered:

On August 6, 2013, we issued 2,000,000 shares of our Series B Preferred Stock. The terms of the statement of designation allow us to issue additional shares of the Series B Preferred Stock.

On January 21, 2014, we issued 4,000,000 shares of our Series C Preferred Stock. The terms of the statement of designation allow us to issue additional shares of the Series C Preferred Stock.

On May 13, 2015, we issued 4,000,000 shares of our Series D Preferred Stock. The terms of the statement of designation allow us to issue additional shares of the Series D Preferred Stock.

On January 30, 2018, we issued 4,600,000 shares of our Series E Preferred Stock. The terms of the statement of designation allow us to issue additional shares of the Series E Preferred Stock.

The description in the applicable prospectus supplement of any preferred stock we offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable statement of designation or specimen stock certificate, which will be filed with the SEC if we offer preferred stock. For more information on how you can obtain copies of any statement of designation or specimen stock certificate if we offer preferred stock, see “Where You Can Find Additional Information” beginning on page 5 of this prospectus. We urge you to read the applicable statement of designation, the applicable specimen stock certificate and any applicable prospectus supplement in their entirety.

We may offer debt securities. The following description of debt securities sets forth the material terms and provisions of the debt securities to which any prospectus supplement may relate. Our debt securities would be issued under an indenture between us and a trustee. The debt securities we may offer may be convertible into common stock or other securities. The indenture, a form of which is included as an exhibit to the registration statement of which this prospectus is a part, will be executed at the time we issue any debt securities. Any supplemental indentures will be filed with the SEC on a Form 6-K or by a post-effective amendment to the registration statement of which this prospectus is a part.

The particular terms of the debt securities offered by any prospectus supplement, and the extent to which the general provisions described below may apply to the offered debt securities, will be described in the applicable prospectus supplement. The indenture will be qualified under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). The terms of the debt securities will include those stated in the indenture and those made part of the indenture by reference to the Trust Indenture Act.

Because the following summaries of the material terms and provisions of the indenture and the related debt securities are not complete, you should refer to the form of the indenture and the debt securities for complete information on some of the terms and provisions of the indenture, including definitions of some of the terms used below, and the debt securities.

The provisions of the indenture do not limit the aggregate principal amount of debt securities which may be issued thereunder. Unless otherwise provided in a prospectus supplement, the debt securities will be our direct, unsecured and unsubordinated general obligations and will have the same rank in liquidation as all of our other unsecured and unsubordinated debt. The debt securities may be convertible into common stock or other securities if specified in the applicable prospectus supplement.

We may issue debt securities from time to time in one or more series. The provisions of the indenture allow us to “reopen” a previous issue of a series of debt securities and issue additional debt securities of that series. The debt securities may be denominated and payable in U.S. dollars or other currencies. We may also issue debt securities from time to time with the principal amount or interest payable on any relevant payment date to be determined by reference to one or more currency exchange rates, securities or baskets of securities, commodity prices or indices. Holders of these types of debt securities will receive payments of principal or interest that depend upon the value of the applicable currency, security or basket of securities, commodity or index on the relevant payment dates.

Debt securities may bear interest at a fixed rate, which may be zero, a floating rate, or a rate which varies during the lifetime of the debt security. Debt securities bearing no interest or interest at a rate that at the time of issuance is below the prevailing market rate may be sold at a discount below their stated principal amount.

The applicable prospectus supplement will contain, where applicable, the following terms of, and other information relating to, any offered debt securities:

Some of the debt securities may be issued as original issue discount securities. Original issue discount securities bear no interest or bear interest at below-market rates and may be sold at a discount below their stated principal amount. The applicable prospectus supplement will contain information relating to income tax, accounting, and other special considerations applicable to original issue discount securities.

Holders may present debt securities for exchange, and holders of registered debt securities may present these securities for transfer, in the manner, at the places and subject to the restrictions stated in the debt securities and described in the applicable prospectus supplement. We will provide these services without charge except for any tax or other governmental charge payable in connection with these services and subject to any limitations or requirements provided in the indenture or the supplemental indenture or issuer order under which that series of debt securities is issued. Holders may transfer debt securities in bearer form and/or the related coupons, if any, by delivery to the transferee. If any of the securities are held in global form, the procedures for transfer of interests in those securities will depend upon the procedures of the depositary for those global securities.

The indenture provides holders of debt securities with remedies if we fail to perform specific obligations, such as making payments on the debt securities, or if we become bankrupt. Holders should review these provisions and understand which actions trigger an event of default and which actions do not. The indenture permits the issuance of debt securities in one or more series, and, in many cases, whether an event of default has occurred is determined on a series-by-series basis.

An event of default is defined under the indenture, with respect to any series of debt securities issued under the indenture, as any one or more of the following events, subject to modification in a supplemental indenture, each of which we refer to in this prospectus as an event of default, having occurred and be continuing:

The indenture provides that, unless otherwise set forth in a supplemental indenture:

In some circumstances, if any and all events of default under the indenture, other than the non-payment of the principal of the securities that has become due as a result of an acceleration, have been cured, waived or otherwise remedied, then the holders of a majority in aggregate principal amount of all series of outstanding debt securities affected, voting as one class, may annul past declarations of acceleration or waive past defaults of the debt securities.

The indenture provides that the trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the holders of debt securities issued under the

indenture relating to the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred upon the trustee. In addition, the indenture contains a provision entitling the trustee, subject to the duty of the trustee to act with the required standard of care during a default, to be indemnified to its satisfaction by the holders of debt securities issued under the indenture before proceeding to exercise any right or power at the request of holders. Subject to these provisions and specified other limitations, the holders of a majority in aggregate principal amount of each series of outstanding debt securities of each affected series, voting as one class, may 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.

The indenture provides that no individual holder of debt securities may institute any action against us under the indenture, except actions for payment of overdue principal and interest, unless the following actions have occurred:

The indenture contains a covenant that we will file annually with the trustee a certificate of no default or a certificate specifying any default that exists.

We have the ability to eliminate most or all of our obligations on any series of debt securities prior to maturity if we comply with the following provisions:

Discharge of Indenture. We may discharge all of our obligations, other than as to transfers and exchanges, under the indenture after we have:

Defeasance of a Series of Securities at Any Time. We may also discharge all of our obligations, other than as to transfers and exchanges, under any series of debt securities at any time, which we refer to as defeasance in this prospectus. We may be released with respect to any outstanding series of debt securities from the obligations imposed by any covenants and elect not to comply with those covenants without creating an event of default. Discharge under those procedures is called covenant defeasance.

Defeasance or covenant defeasance may be effected only if, among other things:

Modification without Consent of Holders. We and the trustee may enter into supplemental indentures without the consent of the holders of debt securities issued under the indenture to:

Modification with Consent of Holders. We and the trustee, with the consent of the holders of not less than a majority in aggregate principal amount of each affected series of outstanding debt securities, voting as one class, may add any provisions to, or change in any manner or eliminate any of the provisions of, the indenture or modify in any manner the rights of the holders of those debt securities. However, we and the trustee may not make any of the following changes to any outstanding debt security without the consent of each holder that would be affected by the change:

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:

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.

Registered Global Securities. 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 securities to be represented by a registered global security will be described in the prospectus supplement relating to those 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, to exercise any rights of a holder under the indenture. We understand that under existing industry practices, if we request any action of holders 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 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.

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 issue securities in definitive form in exchange for the registered global security that had been held by the depositary. In addition, we may, at any time and in our sole discretion, decide not to 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.

Our Annual Report filed on Form 20-F provides a discussion of the material U.S. federal income tax considerations that may be relevant to prospective investors in our securities.

We may offer and sell, from time to time, some or all of the securities covered by this prospectus up to an aggregate public offering price of $500,000,000. We have registered the securities covered by this prospectus for offer and sale so that those securities may be freely sold to the public. Registration of the securities covered by this prospectus does not mean, however, that those securities necessarily will be offered or sold.

Securities covered by this prospectus may be sold from time to time, in one or more transactions, at market prices prevailing at the time of sale, at prices related to market prices, at a fixed price or prices subject to change, at varying prices determined at the time of sale or at negotiated prices, by a variety of methods including the following:

In effecting sales, brokers or dealers engaged by us may arrange for other brokers or dealers to participate. Broker-dealer transactions may include:

In addition, we may sell any securities covered by this prospectus in private transactions or under Rule 144 of the Securities Act rather than pursuant to this prospectus.

In connection with the sale of securities covered by this prospectus, broker-dealers may receive commissions or other compensation from us in the form of commissions, discounts or concessions. Broker-dealers may also receive compensation from purchasers of the securities for whom they act as agents or to whom they sell as principals or both. Compensation as to a particular broker-dealer may be in excess of customary commissions or in amounts to be negotiated. In connection with any underwritten offering, underwriters may receive compensation in the form of discounts, concessions or commissions from us or from purchasers of the securities for whom they act as agents. Underwriters may sell the securities to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or

commissions from the purchasers for whom they may act as agents. Any underwriters, broker-dealers or agents that participate in the distribution of the securities may be deemed to be “underwriters” within the meaning of the Securities Act and any profit on the sale of the securities by them and any discounts, commissions or concessions received by any of those underwriters, broker-dealers or agents may be deemed to be underwriting discounts and commissions under the Securities Act.

In connection with the distribution of the securities covered by this prospectus or otherwise, we may enter into hedging transactions with broker-dealers or other financial institutions. In connection with such transactions, broker-dealers or other financial institutions may engage in short sales of our securities in the course of hedging the positions they assume with us. We may also sell securities short and deliver the securities offered by this prospectus to close out our short positions. We may also enter into option or other transactions with broker-dealers or other financial institutions, which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus, as supplemented or amended to reflect such transaction. We may also from time to time pledge securities pursuant to the margin provisions of any customer agreements with brokers. Upon default, the broker may offer and sell such pledged securities from time to time pursuant to this prospectus, as supplemented or amended to reflect such transaction.

At any time a particular offer of the securities covered by this prospectus is made, a revised prospectus or prospectus supplement, if required, will be distributed which will set forth the aggregate amount of securities covered by this prospectus being offered and the terms of the offering, including the expected issue price or method of determining the price, the time period during which the offer will be open and whether the purchase period may be extended or shortened, the method and time limits for paying up and delivering securities, name or names of any underwriters, dealers, brokers or agents, any discounts, commissions, concessions and other items constituting compensation from us and any discounts, commissions or concessions allowed or reallowed or paid to dealers. Such prospectus supplement, and, if necessary, a post-effective amendment to the registration statement of which this prospectus is a part, will be filed with the SEC to reflect the disclosure of additional information with respect to the distribution of the securities covered by this prospectus. In order to comply with the securities laws of certain states, if applicable, the securities sold under this prospectus may only be sold through registered or licensed broker-dealers. In addition, in some states the securities may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from registration or qualification requirements is available and is complied with.

In connection with an underwritten offering, we would execute an underwriting agreement with an underwriter or underwriters. Unless otherwise indicated in the revised prospectus or applicable prospectus supplement, such underwriting agreement would provide that the obligations of the underwriter or underwriters are subject to certain conditions precedent and that the underwriter or underwriters with respect to a sale of the covered securities will be obligated to purchase all of the covered securities if any such securities are purchased. We may grant to the underwriter or underwriters an option to purchase additional securities at the public offering price, as may be set forth in the revised prospectus or applicable prospectus supplement. If we grant any such option, the terms of the option will be set forth in the revised prospectus or applicable prospectus supplement.

Pursuant to a requirement by the Financial Industry Regulatory Authority, or “FINRA”, if more than five percent of the net proceeds of any offering of securities made under this prospectus will be received by any FINRA member participating in the offering or by affiliates or associated persons of such FINRA member or any participating member who otherwise would have a “conflict of interest” under FINRA Rules, the offering will be conducted in accordance with FINRA Rule 5121.

Underwriters, agents, brokers or dealers may be entitled, pursuant to relevant agreements entered into with us, to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, that may arise from any untrue statement or alleged untrue statement of a material fact, or any omission or alleged omission to state a material fact in this prospectus, any supplement or amendment hereto, or in the registration statement of which this prospectus forms a part, or to contribution with respect to payments which the underwriters, agents, brokers or dealers may be required to make.

We will bear all costs relating to all of the securities being registered under the registration statement of which this prospectus is a part.

The following are the expenses estimated to be incurred by us in connection with a possible offering of $500,000,000 of the securities registered under this registration statement.

The validity of the securities that may be offered by this prospectus and certain other matters relating to Marshall Islands law will be passed upon for us by Cozen O’Connor, New York, New York. Certain other legal matters relating to United States law will be passed upon for us by Cravath, Swaine & Moore LLP, New York, New York.

We are a corporation of the Republic of the Marshall Islands (the “Marshall Islands”). Section 60 of the Business Corporations Act of the Marshall Islands (the “BCA”) provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that such person is or was a director or officer of the corporation, or is or was serving at the request of the corporation as a director or officer of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe such person’s conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of no contest, or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which such person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe such person’s conduct was unlawful.

A Marshall Islands corporation also has the power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that such person is or was a director or officer of the corporation, or is or was serving at the request of the corporation as a director or officer of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys’ fees) actually and reasonably incurred by such person or in connection with the defense or settlement of such action or suit if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable for negligence or misconduct in the performance of such person’s duty to the corporation unless and only to the extent that the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the court shall deem proper.

To the extent that a director or officer of a Marshall Islands corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in the preceding paragraphs, or in the defense of a claim, issue or matter therein, such director or officer shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by such director or officer in connection therewith. Expenses incurred in defending a civil or criminal action, suit or proceeding may be paid in advance of the final disposition of such action, suit or proceeding as authorized by the board of directors in the specific case upon receipt of an undertaking by or on behalf of the director or officer to repay such amount if it shall ultimately be determined that such director or officer is not entitled to be indemnified by the corporation as authorized under Section 60 of the BCA.

Section 60 of the BCA also permits a Marshall Islands corporation to purchase and maintain insurance on behalf of any person who is or was a director or officer of the corporation or is or was serving at the request of the corporation as a director or officer against any liability asserted against such person and incurred by such person in such capacity whether or not the corporation would have the power to indemnify such person against such liability under the provisions of Section 60 of the BCA.

The indemnification and advancement of expenses provided by, or granted pursuant to, Section 60 of the BCA are not exclusive of any other rights to which those seeking indemnification and advancement of expenses may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in such person’s official capacity and as to action in another capacity while holding such office.

The Company’s articles of incorporation include a provision that eliminates the personal liability of directors for monetary damages for actions taken as a director to the fullest extent permitted by law.

The Company’s bylaws provide that the Company must indemnify, to the fullest extent permitted by applicable law, any person who was or is made or is threatened to be made a party to or a witness in or is otherwise involved in any action, suit, claim, inquiry or proceeding, whether civil, criminal, administrative or investigative (including an action by or in the right of the Company) and whether formal or informal, by reason of the fact that such person, or any other person for whom such person is the legal representative, is or was a director or officer of the Company or is or was serving at the Company’s request as a director, officer, employee, trustee or agent of another entity or of a partnership, joint venture, trust, nonprofit entity or other entity (including service with respect to employee benefit plans) against all liability and loss suffered, and expenses (including attorneys’ fees) actually and reasonably incurred, by such person in connection with such action, suit, claim, inquiry or proceeding. The Company’s bylaws also expressly authorize the advancement of certain expenses (including attorneys’ fees and disbursements and court costs) to directors and officers and the carrying of directors’ and officers’ insurance providing indemnification for the Company’s directors, officers and certain employees for some liabilities.

Reference is made to the Index to Exhibits included herewith which is incorporated herein by reference.

The undersigned registrant hereby undertakes:

To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, as amended;

(ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) of the Securities Act of 1933, as amended, if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that paragraphs (i), (ii) and (iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of this registration statement.

That, for the purpose of determining any liability under the Securities Act of 1933, as amended, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

To file a post-effective amendment to the registration statement to include any financial statements required by Item 8.A of Form 20-F at the start of any delayed offering or throughout a continuous offering. Financial statements and information otherwise required by Section 10(a)(3) of the Securities Act of 1933, as amended, need not be furnished, provided that the registrant includes in the prospectus, by means of a post-effective amendment, financial statements required pursuant to this paragraph and other information necessary to ensure that all other information in the prospectus is at least as current as the date of those financial statements. Notwithstanding the foregoing, with respect to registration statements on Form F-3, a post-effective amendment

need not be filed to include financial statements and information required by Section 10(a)(3) of the Securities Act of 1933, as amended, or Item 8A. of Form 20-F, as amended, if such financial statements and information are contained in periodic reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended, that are incorporated by reference in this registration.

That, for the purpose of determining liability under the Securities Act of 1933, as amended, to any purchaser:

(A) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(B) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933, as amended, shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

That, for the purpose of determining liability of the registrant under the Securities Act of 1933, as amended, to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

That, for purposes of determining any liability under the Securities Act of 1933, as amended, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934, as amended (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934, as amended), that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

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

unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933, as amended, and will be governed by the final adjudication of such issue.

To file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the SEC under section 305(b)(2) of the Trust Indenture Act.

Pursuant to the requirements of the Securities Act of 1933, the undersigned Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form F-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in New York, on March 29, 2024.

KNOW ALL PERSONS BY THESE PRESENTS, that each person whose signature appears below constitutes and appoints each of Konstantinos Konstantakopoulos, Gregory Zikos and Anastassios Gabrielides, acting singly, his or her true and lawful attorney-in-fact and agent, with full powers of substitution and re-substitution, for him or her and in his or her name, place and stead, in any and all capacities, to sign any or all amendments (including post-effective amendments) to this registration statement, including any subsequent registration statement for the same offering which may be filed under Rule 462(b) under the Securities Act of 1933, as amended, and to file the same, with all exhibits thereto, and other documents in connection therewith, with the Securities and Exchange Commission, granting unto said attorney-in-fact and agent full power and authority to do and perform each and every act and thing requisite and necessary to be done, as fully for all intents and purposes as he or she might or could do in person, hereby ratifying and confirming all that said attorney-in-fact and agent, or his substitute, may lawfully do or cause to be done by virtue hereof.

Pursuant to the requirements of the Securities Act of 1933, this Registration Statement has been signed below by the following persons in the capacities indicated on March 29, 2024.

Pursuant to the requirement of the Securities Act of 1933, the undersigned, the duly authorized representative in the United States of the aforementioned Registrant, has signed this Registration Statement in Delaware on March 29, 2024.
