We have entered into an Equity Distribution Agreement (the “Distribution Agreement”) with BTIG, LLC, B. Riley Securities, Inc., Clarksons Securities, Inc., and Fearnley Securities, Inc., as our sales agents (the “sales agents”), relating to the common shares of International Seaways, Inc. offered by this prospectus supplement and the accompanying prospectus. In accordance with the terms of the Distribution Agreement, we may offer and sell common shares having an aggregate offering price of up to $200,000,000 from time to time through the sales agents. Sales of shares of our common stock (the “common shares”), if any, under this prospectus supplement and the accompanying prospectus may be made in negotiated transactions, which may include block trades, or transactions that are deemed to be “at the market offerings” as defined in Rule 415(a)(4) under the Securities Act of 1933, as amended (the “Securities Act”), including sales made directly on the New York Stock Exchange (“NYSE”) or sales made to or through a market maker other than on an exchange or as otherwise agreed upon by the sales agents and us. We also may sell some or all of the shares in this offering to a sales agent as principal for its own account at a price per share agreed upon at the time of sale. If we sell shares of our common stock to a sales agent as principal, we will enter into a separate agreement with such sales agent setting forth the terms of such transaction, and, to the extent required by applicable law, we will describe this agreement in a separate prospectus supplement or pricing supplement.

Each sales agent will receive from us a commission of up to 3.0% of the gross sales price of all common shares sold through it as sales agent under the Distribution Agreement. In connection with the sale of common stock, each of the sales agents may be deemed an “underwriter” within the meaning of the Securities Act, and the compensation paid to the sales agents may be deemed to be underwriting commission.

The sales agents are not required to sell any specific number or dollar amount of our common shares but will use their commercially reasonable efforts, as our agents and subject to the terms of the Distribution Agreement, to sell the common shares offered, as instructed by us.

Our common shares are listed on the NYSE under the symbol “INSW.” The last reported sale price of our common shares on the NYSE on May 8, 2026 was $91.62 per share.

Investing in our common shares involves risks. You should carefully consider each of the factors described or referred to under “Risk Factors” beginning on page S-7 of this prospectus supplement, page 6 of the accompanying prospectus and in the documents incorporated by reference into this prospectus supplement and accompanying prospectus before you make an investment in our common shares.

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

This document is in two parts. The first part is the prospectus supplement, which describes the specific terms of this offering. The second part is the accompanying base prospectus, which gives more general information, some of which may not apply to this offering. Generally, when we refer to the “prospectus,” we are referring to both parts combined.

This prospectus supplement and the accompanying prospectus are part of a registration statement on Form S-3 that we filed with the Securities and Exchange Commission (the “SEC”), using an automatic shelf registration process. This prospectus supplement contains specific information about us and the terms on which we are offering and selling our common stock. To the extent that any statement made in this prospectus supplement is inconsistent with statements made in the prospectus, the statements made in the prospectus will be deemed modified or superseded by those made in this prospectus supplement.

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 statements so modified or superseded will be deemed not to constitute a part of this prospectus except as so modified or superseded.

Before you purchase shares of our common stock, you should read in their entirety both this prospectus supplement and the accompanying prospectus, together with the additional information described under the sections entitled “Where You Can Find More Information” and “Incorporation of Certain Documents by Reference” before deciding to invest in any of the securities being offered. Neither we nor the sales agents have authorized anyone to provide you with different information. We take no responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you. We are not, and the sales agents are not, making an offer of our common shares in any state or jurisdiction where the offer or sale is not permitted. You should not assume that the information contained in this prospectus or the information we previously filed with the SEC and incorporated by reference herein is accurate as of any date other than its respective date. Our business, financial condition and results of operations and prospects may have changed since those dates.

In this prospectus, unless otherwise specified or the context otherwise requires, we use the terms “the Company,” “INSW,” “we,” “our” and “us” to refer to International Seaways, Inc., a Marshall Islands corporation, and its consolidated subsidiaries. References to “International Seaways, Inc.” refer only to International Seaways, Inc. on an unconsolidated basis, except where the context may require otherwise. The term “you” refers to a prospective investor.

Some of the statements contained in this prospectus supplement and the documents incorporated by reference herein constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. All such statements other than statements of historical facts should be considered forward-looking statements. These statements can be identified by the fact that they do not relate strictly to historical or current facts, and you can often identify these forward-looking statements by the use of forward-looking words such as “outlook,” “believes,” “expects,” “potential,” “continues,” “may,” “will,” “should,” “could,” “seeks,” “approximately,” “predicts,” “intends,” “plans,” “estimates,” “anticipates,” “target,” “projects,” “forecasts,” “shall,” “contemplates” or the negative version of those words or other comparable words. Such forward-looking statements represent our reasonable expectation with respect to future events or circumstances based on various factors and are subject to various risks and uncertainties and assumptions relating to our operations, financial results, financial condition, business, prospects, growth strategy and liquidity. Accordingly, there are or will be important factors, many of which are beyond our control, that could cause our actual results to differ materially from those indicated in these statements. You should not place undue reliance on any forward-looking statements and should consider the following factors, as well as the factors discussed elsewhere in this prospectus supplement, including under “Risk Factors,” when reviewing such statement. We believe that these factors include, but are not limited to:

The factors identified above should not be construed as an exhaustive list of factors that could affect our future results, and should be read in conjunction with the other cautionary statements that are included elsewhere in this prospectus supplement. The forward-looking statements made in this prospectus supplement are made only as of the date of this prospectus supplement. The forward-looking statements made in documents incorporated by reference into this prospectus supplement are made only as of the date of such documents. The forward-looking statements made in any accompanying prospectus supplement are made only as of the date of such document. We do not undertake any obligation to publicly update or review any forward-looking statement except as required by law, whether as a result of new information, future developments or otherwise. If we do update one or more forward-looking statements, no inference should be made that we will make additional updates with respect to those or other forward-looking statements.

If one or more of these or other risks or uncertainties materialize, or if our underlying assumptions prove to be incorrect, our actual results may vary materially from what we may have expressed or implied by these forward-looking statements. We caution that you should not place undue reliance on any of our forward-looking statements. You should specifically consider the factors identified in this prospectus supplement that could cause actual results to differ before making an investment decision to purchase our common shares. Furthermore, new risks and uncertainties arise from time to time, and it is impossible for us to predict those events or how they may affect us.

You should refer to our periodic and current reports filed with the SEC for further information on other factors that could cause actual results to be significantly different from those expressed or implied by these forward-looking statements. See “Where You Can Find More Information” and “Incorporation of Certain Documents by Reference” in this prospectus supplement.

Our Company

We are a provider of ocean transportation services for crude oil and refined petroleum products. We operate our vessels in the International Flag market. Our business includes two reportable segments: Crude Tankers and Product Carriers. For the three months ended March 31, 2026 and 2025, we derived 58% and 47%, respectively, of our time charter equivalent (“TCE”) revenues from our Crude Tankers segment. Revenues from our Product Carriers segment constituted the balance of our TCE revenues in the 2026 and 2025 periods.

As of March 31, 2026, our operating fleet consisted of 64 wholly-owned or lease financed and time chartered-in vessels aggregating 7.6 million deadweight tons (“dwt”). In addition to our operating fleet of 64 vessels, three LR1 newbuilds are scheduled for delivery to us between the second and third quarters of 2026, bringing the total operating and newbuild fleet to 67 vessels. Our fleet includes VLCC, Suezmax and Aframax crude tankers and LR2, LR1 and MR product carriers. In addition to our operating fleet, Tankers International Suezmax Limited, a variable interest entity that is consolidated by us, had one Suezmax tanker time chartered-in from a third-party under its pool participation agreement as of March 31, 2026.

Risk Factors	An investment in our common shares involves risks. You should carefully consider each of the factors described or referred to under “Risk Factors” beginning on page S-7 of this prospectus supplement, page 6 of the accompanying prospectus and in the documents incorporated by reference into this prospectus supplement and accompanying prospectus before you make an investment in our common shares.

An investment in our securities involves a high degree of risk. You should carefully consider the specific risks described under the heading “Risk Factors” in any applicable prospectus supplement and in the documents incorporated by reference into this prospectus, including our most recently filed Annual Report on Form 10-K and any subsequently filed Quarterly Report on Form 10-Q, before making an investment decision. If any of the risks described in these documents actually materializes, our business, financial condition, results of operations and prospects could be materially adversely affected. As a result, the value of our securities could decline and you could lose part or all of your investment. The risks described below are not the only ones we face. There may be other unknown or unpredictable economic, business, competitive, regulatory or other factors that could have material adverse effects on our future results. Past financial performance may not be a reliable indicator of future performance and historical trends should not be used to anticipate results or trends in future periods.

Our common stock is listed on the NYSE. The market price of our common stock may fluctuate substantially. You may not be able to resell your common stock at or above the price you paid for such securities due to a number of factors, some of which are beyond our control. These risks include those described or referred to in this “Risk Factors” section and under “Cautionary Note Regarding Forward-Looking Statements,” as well as, among other things: fluctuations in our operating results; activities of and results of operations of our competitors; changes in our relationships with our customers or our vendors; changes in business or regulatory conditions; changes in our capital structure; any announcements by us or our competitors of significant acquisitions, strategic alliances or joint ventures; additions or departures of key personnel; investors’ general perception of us; failure to meet market expectations; future sales of our securities by us and our directors, executives and significant stockholders; changes in domestic and international economic and political conditions; and other events or factors, including those resulting from natural disasters, war, acts of terrorism or responses to these events. Any of the foregoing factors could also cause the price of our equity securities to fall and may expose us to securities class action litigation. Any securities class action litigation could result in substantial costs and the diversion of management’s attention and resources.

In addition, the stock market has recently experienced volatility that, in some cases, has been unrelated or disproportionate to the operating performance of particular companies. These broad market and industry fluctuations may adversely affect the market price of our common stock, regardless of our actual operating performance.

If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, the price and/or trading volume of shares of our common stock could decline.

The trading market for shares of our common stock depends, in part, on the research and reports that securities or industry analysts publish about us and our business. If too few analysts commence and maintain coverage of us, the trading price for our shares might be adversely affected. Similarly, if analysts publish inaccurate or unfavorable research about our business, the price and/or trading volume of shares of our common stock could decline.

Our limited duration Second Amended and Restated Stockholders Rights plan dated as of April 6, 2026 (the “Second Amended and Restated Rights Plan”), also known as a “poison pill”, may discourage, delay or prevent a change of control of us or changes in our management and, therefore, depress the market price of our common stock.

The Second Amended and Restated Rights Plan is intended to enable all our stockholders to realize the long-term value of their investment in us. The Second Amended and Restated Rights Plan reduces the likelihood that any person or group gains control of us through open market accumulation, or other tactics potentially disadvantaging the interests of all stockholders, without paying all stockholders an appropriate control premium or providing our Board of Directors sufficient time to make informed decisions in the best interests of all stockholders. While the Second Amended and Restated Rights Agreement was effective immediately, the Rights become exercisable only if a person or group acquires beneficial ownership, as defined in the Second Amended and Restated Rights Plan, of 20% or more of our common stock in a transaction not approved by our Board of Directors. In that situation, each holder of a Right (other than the acquiring person or group) will have the right to purchase, upon payment of the then-current exercise price, a number of shares of our common stock having a market value of twice the exercise price of the Right. In addition, at any time after a person or group acquires 20% or more of our common stock (unless such person or group acquires 50% or more), our Board of Directors may exchange one share of our common stock for each outstanding Right (other than Rights owned by such person or group, which would have become null and void). The Second Amended and Restated Rights Plan is not intended to interfere with any transaction that our Board of Directors determines is in the best interests of stockholders, nor does the Second Amended and Restated Rights Plan prevent the Board of Directors from considering any proposal. The Second Amended and Restated Rights Plan will expire on April 8, 2029, subject to earlier termination by our Board of Directors if the Board of Directors determines that market and other conditions warrant.

Notwithstanding the foregoing advantages provided by the Second Amended and Restated Rights Plan to the interests of all stockholders, the Second Amended and Restated Rights Plan, while in effect, may depress the market price of our common stock by acting to discourage, delay or prevent a change of control of us or changes in the management of us that the stockholders of ours may deem advantageous.

Future offerings of our debt or equity securities may materially adversely affect the share price, and future capitalization measures could lead to substantial dilution of our existing stockholders’ interests.

We may seek to raise additional equity through the issuance of new shares or convertible or exchangeable bonds to finance future organic growth or acquisitions. Increasing the number of issued shares would dilute the ownership interests of existing stockholders. Stockholders’ ownership interests could also be diluted if other companies or equity interests in companies are acquired in exchange for new shares of our common stock to be issued and if our Board of Directors makes grants of equity awards to our directors, officers and employees pursuant to any equity incentive or compensation plan, any such grants would also cause dilution. Because the sales of the shares offered hereby will be made directly into the market or in negotiated transactions, the prices at which we sell these shares will vary and these variations may be significant. Purchasers of the shares we sell, as well as our existing shareholders, will experience significant dilution if we sell shares at prices significantly below the price at which they invested.

During 2025, 2024 and 2023, we paid regular quarterly and supplemental cash dividends totaling $144.6 million or $2.93 per share, $284.4 million or $5.77 per share, and $308.2 million or $6.29 per share, respectively. Additionally, in the first quarter of 2026, we paid a regular quarterly and supplemental cash dividend totaling $106.4 million or $2.15 per share and on May 6, 2026, we announced a regular quarterly and supplemental cash dividend totaling $4.55 per share to be paid on June 26, 2026 to stockholders of record as of June 12, 2026. Any future determinations to pay dividends on our common stock will be at the discretion of our Board of Directors and will depend upon many factors, including our future operations and earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors our Board of Directors may deem relevant. The timing, declaration, amount and payment of any future dividends will be at the discretion of our Board of Directors. We have no obligation to, and may not be able to, declare or pay dividends on our common stock. If we do not declare and pay dividends on our common stock, our share price could decline.

We are a holding company and depend on the ability of our subsidiaries to distribute funds to us in order to satisfy our financial obligations or pay dividends.

We are a holding company and our subsidiaries conduct all of our operations and own all of our operating assets. We have no significant assets other than the equity interests in our subsidiaries. As a result, our ability to satisfy our financial obligations or pay dividends depends on our subsidiaries and their ability to distribute funds to us. In addition, the terms of certain of our financing agreements restrict the ability of certain of those subsidiaries to distribute funds to us.

Some provisions of Marshall Islands law and our governing documents could discourage a takeover that stockholders may consider favorable, or otherwise influence our ability to consummate a change of control.

Marshall Islands law and provisions contained in our amended and restated certificate of incorporation (“Amended and Restated Articles of Incorporation”) and amended and restated by-laws (“Amended and Restated By-Laws”) could have the effect of delaying, deferring or preventing a change of control of us. In addition, these provisions could make it more difficult to bring about a change in the composition of our Board of Directors. For example, our Amended and Restated Articles of Incorporation and Amended and Restated By-Laws:

These and other provisions of our organizational documents and Marshall Islands law may have the effect of delaying, deferring or preventing changes of control or changes in management, even if such transactions or changes would have significant benefits for our stockholders. See “Description of Capital Stock.” As a result, these provisions could limit the price some investors might be willing to pay in the future for shares of our common stock.

We are incorporated in the Marshall Islands, which does not have a well-developed body of corporate case law or bankruptcy law, and, as a result, shareholders may have fewer rights and protections under Marshall Islands law than under a typical jurisdiction in the United States.

Our corporate affairs are governed by our articles of incorporation and bylaws and by the Marshall Islands Business Corporations Act (the “BCA”). The provisions of the BCA resemble provisions of the corporation laws of a number of states in the United States. However, there have been few judicial cases in the Marshall Islands interpreting the BCA. The rights and fiduciary responsibilities of directors under the law of the Marshall Islands are not as clearly established as the rights and fiduciary responsibilities of directors under statutes or judicial precedent in existence in certain U.S. jurisdictions. Shareholder rights may differ as well. While the BCA does specifically incorporate the non-statutory law, or judicial case law, of the State of Delaware and other states with substantially similar legislative provisions, our shareholders may have more difficulty in protecting their interests in the face of actions by management, directors or controlling shareholders than would shareholders of a corporation incorporated in a U.S. jurisdiction. In addition, the Marshall Islands does not have a well-developed body of bankruptcy law. As such, in the case of a bankruptcy involving us, there may be a delay of bankruptcy proceedings and the ability of securityholders and creditors to receive recovery after a bankruptcy proceeding, and any such recovery may be less predictable.

It may be difficult to serve process on or enforce a United States judgment against us, our officers and our directors because we are a foreign corporation.

We are a corporation formed in the Republic of the Marshall Islands. In addition, a substantial portion of our assets are located outside of the United States, principally in Bermuda. As a result, you may have difficulty serving legal process within the United States upon us. You may also have difficulty enforcing, both in and outside the United States, judgments you may obtain in U.S. courts against us or our directors and officers, including in actions based upon the civil liability provisions of U.S. federal or state securities laws. Furthermore, there is substantial doubt that the courts of the Republic of the Marshall Islands or of the non-U.S. jurisdictions in which our offices are located would enter judgments in original actions brought in those courts predicated on U.S. federal or state securities laws.

We have broad discretion in the use of the net proceeds from this offering and our existing cash and may not use them effectively.

Our management will have broad discretion in the application of the net proceeds from this offering, including for any of the purposes described in the section titled “Use of Proceeds,” as well as our existing cash, and you will be relying on the judgment of our management regarding such application. You will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used effectively. Our management might not apply the net proceeds or our existing cash in ways that ultimately increase the value of your investment. If we do not invest or apply the net proceeds from this offering or our existing cash in ways that enhance stockholder value, we may fail to achieve expected results, which could cause our stock price to decline.

The common stock offered hereby will be sold in “at the market offerings,” and investors who buy shares at different times will likely pay different prices.

Investors who purchase shares in this offering at different times will likely pay different prices, and so may experience different outcomes in their investment results. We will have discretion, subject to market demand, to vary the timing, prices and numbers of shares sold, and there is no minimum or maximum sales price. Investors may experience a decline in the value of their shares as a result of share sales made at prices lower than the prices they paid.

The actual number of any shares we may issue and gross proceeds resulting from those sales, at any one time or in total, is uncertain.

Subject to certain limitations in the Distribution Agreement and compliance with applicable law, we have the discretion to deliver a placement notice to the sales agents at any time throughout the term of the Distribution Agreement. The number of shares that are sold by the sales agents after delivering a placement notice will fluctuate based on the market price of our common stock during the sales period and limits we set with the sales agents in any instruction to sell shares, and the demand for our common stock during the sales period. Because the price per share of each share sold will fluctuate based on the market price of our common stock during the sales period, it is not possible at this stage to predict the number of shares that will be ultimately sold or the gross proceeds to be raised in connection with those sales, if any.

We intend to use the net proceeds of this offering, after deducting the sales agents’ commissions and our offering expenses, for general corporate purposes. This may include, among other things, additions to working capital, repayment or refinancing of existing indebtedness or other corporate obligations, financing of capital expenditures and acquisitions and investment in existing and future projects.

The following is a summary of material U.S. federal income tax considerations that are likely to be relevant to the purchase, ownership and disposition of our common stock by a U.S. Holder (as defined below).

This summary is based on provisions of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), and regulations, rulings and judicial interpretations thereof, in force as of the date hereof. Those authorities may be changed at any time, perhaps retroactively, so as to result in U.S. federal income tax consequences different from those summarized below.

This summary is not a comprehensive discussion of all of the tax considerations that may be relevant to a particular investor’s decision to purchase, hold, or dispose of our common stock. In particular, this summary is directed only to U.S. Holders that hold our common stock as capital assets and does not address particular tax consequences that may be applicable to U.S. Holders who may be subject to special tax rules, such as banks, brokers or dealers in securities or currencies, traders in securities electing to mark to market, financial institutions, life insurance companies, tax-exempt entities, regulated investment companies, entities or arrangements that are treated as partnerships for U.S. federal income tax purposes (or partners therein), holders that own or are treated as owning 10% or more of our common stock by vote or value, persons holding our common stock as part of a hedging or conversion transaction or a straddle, or persons whose functional currency is not the U.S. dollar.

This summary addresses only U.S. federal income tax consequences, and does not address consequences arising under state, local, foreign tax laws, any alternative minimum tax or the Medicare tax on net investment income or under special timing rules prescribed under section 451(b) of the Code.

For purposes of this summary, a “U.S. Holder” is a beneficial owner of our common stock that is a citizen or resident of the United States or a U.S. domestic corporation or that otherwise is subject to U.S. federal income taxation on a net income basis in respect of our common stock.

You should consult your own tax advisors about the consequences of the acquisition, ownership, and disposition of our common stock, including the relevance to your particular situation of the considerations discussed below and any consequences arising under foreign, state, local or other tax laws.

Subject to the discussion below under “—Passive Foreign Investment Company Status,” the gross amount of any distribution of cash or property with respect to our common stock that is paid out of our current or accumulated earnings and profits (as determined for U.S. federal income tax purposes) will generally be includible in your taxable income as ordinary dividend income and will not be eligible for the dividends-received deduction allowed to corporations under the Code.

The U.S. dollar amount of dividends received by an individual with respect to our common stock will be subject to taxation at a preferential rate if the dividends are “qualified dividends.” Subject to certain exceptions for short-term positions, dividends paid on our common stock will be treated as qualified dividends if:

Our common stock is listed on the New York Stock Exchange, and will qualify as readily tradable on an established securities market in the United States so long as it is so listed. As discussed in more detail below under “—Passive Foreign Investment Company Status,” based on our financial statements and relevant market and shareholder data, we do not believe that we were a PFIC in our prior taxable year. In addition, based on our financial statements and our current expectations regarding the value and nature of our assets, the sources and nature of our income, the nature of our activities, the market value of our equity, and relevant market and shareholder data, we do not expect to become a PFIC in our current taxable year. Holders should consult their own tax advisors regarding the availability of the reduced dividend tax rate in light of their own particular circumstances.

Dividend distributions with respect to our common stock generally will be treated as “passive category” income from sources outside the United States for purposes of determining a U.S. Holder’s U.S. foreign tax credit limitation.

U.S. Holders that receive distributions of our common stock or rights to subscribe for our common stock as part of a pro rata distribution to all our shareholders generally will not be subject to U.S. federal income tax in respect of the distributions, unless the U.S. Holder has the right to receive cash or property, in which case the U.S. Holder will be treated as if it received cash equal to the fair market value of the distribution.

Subject to the discussion below under “—Passive Foreign Investment Company Status,” upon a sale, exchange or other taxable disposition of our common stock, a U.S. Holder will realize gain or loss for U.S. federal income tax purposes in an amount equal to the difference between the amount realized on the disposition and the U.S. Holder’s adjusted tax basis in our common stock. Such gain or loss will be capital gain or loss, and will generally be long-term capital gain or loss if our common stock has been held for more than one year. Long-term capital gain realized by a U.S. Holder that is an individual generally is subject to taxation at a preferential rate. The deductibility of capital losses is subject to limitations.

Capital gain or loss recognized by a U.S. Holder on the sale or other disposition of our common stock generally will be U.S. source gain or loss for U.S. foreign tax credit purposes.

Special U.S. tax rules apply to investors in companies that are considered to be PFICs. We will be classified as a PFIC in a particular taxable year if, after applying certain look-through rules, either

We refer to assets that produce or are held for the production of passive income as “passive assets.” For purposes of these tests, “passive income” generally includes dividends, interest, gains from the sale or exchange of investment property and rental income and royalties other than rental income and royalties which are received from unrelated parties in connection with the active conduct of a trade or business, as defined in applicable U.S. Treasury regulations. Passive income does not include income derived from the performance of services. Although there is no authority under the PFIC rules that is directly on point, and existing legal authority in other contexts is inconsistent in its treatment of time charter income, we believe that the gross income we derive or are deemed to derive from our time and spot chartering activities is services income, rather than rental income.

Accordingly, we believe that (i) our income from time and spot chartering activities does not constitute passive income and (ii) the assets that we own and operate in connection with the production of that income do not constitute passive assets. Therefore, based on our financial statements and our expectations about the nature and amount of our income, assets and activities, and the market value of our equity, we do not believe we were a PFIC in our prior taxable year and do not expect to be a PFIC in our current taxable year. There is no assurance that the U.S. Internal Revenue Service (the “IRS”) or a court of law will accept our position, and there is a risk that the IRS or a court of law could determine that we are a PFIC. Moreover, there are uncertainties in the application of the PFIC rules with respect to our business, and the determination as to whether we are a PFIC must be made annually after the close of each taxable year and be based on the facts and circumstances at that time, and is therefore subject to change. Accordingly, there can be no assurance that we will not be a PFIC for any year in which a U.S. Holder holds our common stock.

If we are a PFIC for any taxable year and any entity in which we own or are deemed to own equity interests is also a PFIC (a “Lower-tier PFIC”), a U.S. Holder will be deemed to own a proportionate amount (by value) of the shares of each Lower-tier PFIC and will be subject to U.S. federal income tax according to the rules described in the next paragraph on (i) certain distributions by the Lower-tier PFIC and (ii) dispositions of shares of the Lower-tier PFIC, in each case as if the U.S. Holder held such shares directly, even though the U.S. Holder will not receive any proceeds of those distributions or dispositions.

If we are classified as a PFIC, and you do not make a mark-to-market election as described below, you will be subject to a special tax at ordinary income tax rates on “excess distributions” (generally, any distributions that you receive in a taxable year that are greater than 125 percent of the average annual distributions that you have received in the preceding three taxable years, or your holding period, if shorter), and gain that that you recognize on the sale of our common stock. Under these rules (a) the excess distribution or gain will be allocated ratably over your holding period, (b) the amount allocated to the current taxable year and any taxable year prior to the first taxable year in which we are a PFIC will be taxed as ordinary income, and (c) the amount allocated to each of the other taxable years will be subject to tax at the highest rate of tax in effect for the applicable class of taxpayer for that year, and an interest charge for the deemed deferral benefit will be imposed with respect to the resulting tax attributable to each such other taxable year. If we are a PFIC for any taxable year during which you own our common stock, we will generally continue to be treated as a PFIC with respect to you for all succeeding years during which you own our common stock, even if we cease to meet the threshold requirements for PFIC status, unless you make a timely “deemed sale” election, in which case any gain on the deemed sale will be taxed under the PFIC rules described above.

You may be able to mitigate some of the unfavorable rules described in the preceding paragraph by electing to mark our common stock to market, provided our common stock is considered “marketable.” Our common stock will be marketable if it is regularly traded on certain qualifying U.S. stock exchanges, including the New York Stock Exchange, or on a foreign stock exchange that meets certain requirements. If you make this mark-to-market election, you will be required in any year in which we are a PFIC to include as ordinary income the excess of the fair market value of our common stock at the end of your taxable year over your basis in such stock. If at the end of your taxable year, your basis in our common stock exceeds its fair market value, you will be entitled to deduct the excess as an ordinary loss, but only to the extent of your net mark-to-market gains from previous years. Your adjusted tax basis in the common stock will be adjusted to reflect any income or loss recognized under these rules. In addition, any gain you recognize upon the sale of our common stock will be taxed as ordinary income in the year of sale and any loss will be treated as an ordinary loss to the extent of your net mark-to-market gains from previous years. Once made, the election cannot be revoked without the consent of the IRS unless our common stock ceases to be marketable. A mark-to-market election cannot be made with respect to any Lower-tier PFIC unless the shares of such Lower-tier PFIC are themselves “marketable.” As a result, if you make a mark-to-market election with respect to our common stock, you could nevertheless be subject to the PFIC rules described in the preceding paragraph with respect to your indirect interest in any Lower-tier PFIC. Prospective investors should consult their own tax advisor regarding the availability and advisability of making a mark-to-market election in their particular circumstances if we are a PFIC for any taxable year.

If we are a PFIC (or treated as a PFIC with respect to you) for any taxable year in which we pay a dividend or the preceding taxable year, the favorable tax rate described above with respect to dividends paid to certain non-corporate U.S. Holders will not apply.

A U.S. Holder that owns an equity interest in a PFIC generally must annually file IRS Form 8621, and may be required to file other IRS forms. A failure to file one or more of these forms as required may toll the running of the statute of limitations in respect of each of your taxable years for which such form is required to be filed. As a result, the taxable years with respect to which you fail to file the form may remain open to assessment by the IRS indefinitely, until the form is filed.

Prospective investors should consult their own tax advisor regarding the potential application of the PFIC rules to an investment in our common stock.

Individual U.S. Holders that own “specified foreign financial assets” with an aggregate value in excess of U.S.$50,000 on the last day of the taxable year, or U.S.$75,000 at any time during the taxable year, are generally required to file an information statement along with their tax returns, currently on IRS Form 8938, with respect to such assets. “Specified foreign financial assets” include any financial accounts held at a non-U.S. financial institution, as well as securities issued by a non-U.S. issuer that are not held in accounts maintained by financial institutions. Higher reporting thresholds apply to certain individuals living abroad and to certain married individuals. Regulations extend this reporting requirement to certain entities that are treated as formed or availed of to hold direct or indirect interests in specified foreign financial assets based on objective criteria. U.S. Holders who fail to report the required information could be subject to substantial penalties. In addition, the statute of limitations for assessment of tax would be suspended, in whole or part. Prospective investors are encouraged to consult with their own tax advisors regarding the possible application of these rules, including the application of the rules to their particular circumstances.

Dividends paid to, and proceeds from a sale or other disposition by, a U.S. Holder in respect of our common stock generally may be subject to the information reporting requirements of the Code and may be subject to backup withholding unless the U.S. Holder provides an accurate taxpayer identification number and makes any other required certification or otherwise establishes an exemption. Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a refund or credit against the U.S. Holder’s U.S. federal income tax liability, provided the required information is furnished to the IRS in a timely manner.

A holder that is not a “United States person” (as defined in the Code) may be required to comply with certification and identification procedures in order to establish its exemption from information reporting and backup withholding.

The following is a discussion of the current laws of the Republic of the Marshall Islands applicable to persons who do not reside in, maintain offices in or engage in business in the Republic of the Marshall Islands.

Because we do not, and we do not expect that we will, conduct business or operations in the Republic of the Marshall Islands, and because all documentation related to this offering will be executed outside of the Republic of the Marshall Islands, under current Marshall Islands law you will not be subject to Marshall Islands taxation or withholding on payments we make to you with respect to our common stock. In addition, you will not be subject to Marshall Islands stamp, capital gains or other taxes on the purchase, ownership or disposition of our common stock, and you will not be required by the Republic of the Marshall Islands to file a tax return relating to our common stock.

Each prospective noteholder is urged to consult its tax counsel or other advisor with regard to the legal and tax consequences, under the laws of pertinent jurisdictions, including the Marshall Islands, of its investment in our common stock. Further, it is the responsibility of each holder to file all state, local and non-U.S., as well as U.S. federal, tax returns that may be required of it.

We have entered into the Distribution Agreement with BTIG, LLC, B. Riley Securities, Inc., Clarksons Securities, Inc., and Fearnley Securities, Inc., as our sales agents, under which we may offer and sell from time to time, up to an aggregate initial offering price of $200,000,000 of our common shares through the sales agents. Sales of our common shares, if any, will be made in privately negotiated transactions, as block transactions or by any other method or payment permitted by law deemed to be an “at-the-market” offering as defined in Rule 415(a)(4) under the Securities Act, including sales made directly on the NYSE or sales made to or through a market maker, or otherwise in negotiated transactions at market prices prevailing at the time of sale or at negotiated prices, or as otherwise agreed with the sales agents. As sales agents, BTIG, LLC, B. Riley Securities, Inc., Clarksons Securities, Inc., and Fearnley Securities, Inc. will not engage in any prohibited stabilizing transactions in connection with the sale of our common shares.

The sales agents will offer our common shares subject to the terms and conditions of the Distribution Agreement. We will designate the minimum price per share at which the common shares may be sold and the maximum amount of common shares to be sold through the sales agents during any selling period or otherwise determine such maximum amount together with the sales agents. Subject to the terms and conditions of the Distribution Agreement, the sales agents have agreed to use their commercially reasonable efforts to execute our orders to sell, as our sales agents and on our behalf, our common shares submitted to the sales agents from time to time pursuant to and subject to the terms of the Distribution Agreement. We or the sales agents may suspend the offering of common shares under the Distribution Agreement by proper notice to the other party.

We will pay each sales agent a commission of up to 3.0% of the gross sales price of all common shares sold through it as sales agent under the Distribution Agreement. We have agreed to reimburse the sales agent for certain expenses in certain circumstances, including fees and disbursements related to their legal counsel, in an amount not to exceed $65,000, in addition to certain ongoing fees and disbursements of its legal counsel. We estimate that the total expenses for the offering payable by us, excluding compensation payable to the sales agents under the terms of the Distribution Agreement, will be approximately $600,000. The net proceeds from the offering of shares hereunder will equal the gross proceeds, less the sales agents’ commissions less any expenses payable by us and any transaction fees imposed by any governmental or self-regulatory organization in connection with the sales. Settlement for sales of common shares will occur, unless the parties agree otherwise, on the first trading day following the date on which any sales were made against payment of the net proceeds to us. A trading day is any trading day on the NYSE.

Under the terms of the Distribution Agreement, we also may sell our common shares to a sales agent as principal for its own account, at a price agreed upon at the time of sale. If we sell shares to a sales agent as principal, we will enter into a separate agreement with such sales agent in substantially the form of Annex A of the Distribution Agreement, relating to such sale in accordance with Section 3 thereof, and, to the extent required by applicable law, we will describe such agreement in a separate prospectus supplement or pricing supplement.

We will report in a prospectus supplement or our filings with the SEC under the Securities Exchange Act of 1934, as amended, at least quarterly the number of our common shares sold through the sales agents under the Distribution Agreement, the net proceeds to us and the compensation paid by us to the sales agents in connection with the sales of our common shares.

In connection with the sale of the common shares on our behalf, the sales agents, as registered broker dealers participating in the distribution of securities under this prospectus, may each be deemed an “underwriter” within the meaning of the Securities Act, and the compensation paid to the sales agents may be deemed to be underwriting commissions or discounts. We have agreed in the Distribution Agreement to provide indemnification and contribution to the sales agents against certain civil liabilities, including liabilities under the Securities Act.

Each sales agent and its respective affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us or our affiliates. They have received, or may in the future receive, customary fees and commissions for these transactions. In September 2025, Clarksons Securities AS and Fearnleys Securities AS acted as passive Joint Lead Managers in the Company's placement of $250 million of new senior unsecured bonds in the Nordic bond market.

The offering of common shares pursuant to the Distribution Agreement will terminate upon the earlier of (i) the sale of all of the common shares subject to the Distribution Agreement or (ii) the termination of the Distribution Agreement, pursuant to its terms.

Certain legal matters in connection with the offering will be passed upon for us by Cleary Gottlieb Steen & Hamilton LLP, New York, New York. The validity of the common shares offered hereby and certain other legal matters with respect to the laws of the Republic of the Marshall Islands and otherwise will be passed upon for us by Reeder & Simpson, P.C., a Marshall Islands law firm. Goodwin Procter LLP, New York, New York, will pass upon certain legal matters in connection with the offering on behalf of the sales agents.

This prospectus is part of a registration statement on Form S-3 that we filed with the Securities and Exchange Commission (the “SEC”) using an automatic shelf registration process. Under this shelf registration process, we may, from time to time, offer and sell the securities described in this prospectus in one or more offerings. This prospectus generally describes International Seaways, Inc. and the securities we may offer. Under this shelf registration process, we may, from time to time, sell any combination of the securities described in this prospectus in one or more offerings through any means described in the section entitled “Plan of Distribution.”

This prospectus only provides you with a general description of the securities that may be offered. Each time we sell securities using this shelf registration, a supplement to this prospectus containing specific information about the terms of that offering will also be provided to you. Any such prospectus supplement may also add, update or change information contained in this prospectus. If there is any inconsistency between the information in this prospectus and any applicable prospectus supplement, you should rely on the information in any applicable prospectus supplement. You should read in their entirety both this prospectus and any accompanying prospectus supplement, together with the additional information described under the sections entitled “Where You Can Find More Information” and “Incorporation of Certain Documents by Reference” before deciding to invest in any of the securities being offered.

You should not assume that the information in this prospectus, any accompanying prospectus supplement or any document incorporated by reference herein is accurate as of any date other than the date on the front of each document, regardless of the time of delivery of this prospectus, any accompanying prospectus supplement or any sale of securities.

Neither the delivery of this prospectus nor any sale made under it implies that there has been no change in our affairs or that the information in this prospectus is correct as of any date after the date of this prospectus.

You should rely only on the information contained in or incorporated by reference in this prospectus, in any accompanying prospectus supplement or in any free writing prospectus filed by us with the SEC. We have not authorized anyone to provide you with different information. We are not making an offer of these securities in any jurisdiction where the offer is not permitted.

This summary highlights information contained elsewhere in, or incorporated by reference into, this prospectus. As a result, it may not contain all the information that may be important to you in, or that you should consider before making a decision as to whether or not to invest in our securities, and is qualified in its entirety by the more detailed information included in and incorporated by reference into this prospectus. You should read the entire prospectus carefully, including the section entitled “Risk Factors” and the documents incorporated by reference herein, which are described under “Incorporation of Certain Documents by Reference,” before making an investment decision. For a more complete description of our business as of the date of this prospectus, see the “Business” section of our Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on February 27, 2025 (Commission File No. 001-37836) (the “Form 10-K”), and see our Quarterly Report on Form 10-Q for the quarter ended September 30, 2025, filed with the SEC on November 6, 2025, as well as the most recently filed Annual Report on Form 10-K and any subsequently filed Quarterly Report on Form 10-Q, each of which is incorporated by reference herein.

A glossary of shipping terms that should be used as a reference when reading this prospectus and the documents incorporated by reference herein can be found in the Form 10-K.

We are a leading provider of ocean transportation services for crude oil and refined petroleum products. We own or operate a fleet of vessels that operate in International Flag markets. We serve a diverse group of customers, including major independent and state-owned oil companies, oil traders and refinery operators, and have a reputation in the industry for excellent service.

Our vessel operations are organized into two segments: Crude Tankers and Product Carriers. Our fleet consists of VLCC, Suezmax and Aframax crude tankers, as well as LR1, LR2 and MR product carriers. We operate a fleet of 74 vessels (including newbuildings).

INSW generally charters its vessels to customers either for specific voyages at spot rates or for specific periods of time at fixed daily amounts through time charters or bareboat charters. Spot market rates are highly volatile, while time charter and bareboat charter rates provide more predictable streams of time charter equivalent (“TCE”) revenues because they are fixed for specific periods of time. Shipping revenues from our fleet, derived primarily through spot market voyage charters, were $951.6 million during 2024 and $575.4 million during the first nine months of 2025, while TCE revenues (shipping revenues less voyage expenses) were $933.1 million and $559.6 million during each of those periods, respectively.

Our executive offices are located at 600 Third Avenue, 39^th Floor, New York, New York 10016, and our telephone number is (212) 578-1600. Our Internet website address is www.intlseas.com. Information on, or accessible through, our website is not incorporated into, nor should it be considered part of, this prospectus or any applicable prospectus supplement, except as and solely to the extent otherwise provided herein or therein. We have included our website address only as an inactive textual reference and do not intend it to be an active link to our website.

An investment in our securities involves a high degree of risk. Before making an investment decision, you should carefully consider the discussion of risks and uncertainties under the heading “Risk Factors” contained in any applicable prospectus supplement and any related free writing prospectus, and under similar headings in our most recent Annual Report on Form 10-K (together with any material changes thereto contained in subsequently filed Quarterly Reports on Form 10-Q or Interim Reports on Form 8-K) and those contained in our other filings with the SEC, which are incorporated by reference in this prospectus (collectively, the “Incorporated Documents”). If any of the risks described in the Incorporated Documents materializes, it could materially and adversely affect our business, financial condition, results of operations and prospects, and cause the value of our securities to decline. We may also be subject to additional risks and uncertainties not presently known to us or that we currently deem immaterial, which could include unknown or unpredictable economic, business, competitive, regulatory or other factors potentially having a material adverse effect on us or the value of our securities.

Some of the statements contained in this prospectus and the documents incorporated by reference herein constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. All such statements other than statements of historical facts should be considered forward-looking statements. These statements can be identified by the fact that they do not relate strictly to historical or current facts, and you can often identify these forward-looking statements by the use of forward-looking words such as “outlook,” “believes,” “expects,” “potential,” “continues,” “may,” “will,” “should,” “could,” “seeks,” “approximately,” “predicts,” “intends,” “plans,” “estimates,” “anticipates,” “target,” “projects,” “forecasts,” “shall,” “contemplates” or the negative version of those words or other comparable words. Such forward-looking statements represent our reasonable expectation with respect to future events or circumstances based on various factors and are subject to various risks and uncertainties and assumptions relating to our operations, financial results, financial condition, business, prospects, growth strategy and liquidity. Accordingly, there are or will be important factors, many of which are beyond our control, that could cause our actual results to differ materially from those indicated in these statements. You should not place undue reliance on any forward-looking statements and should consider the following factors, as well as the factors discussed elsewhere in this prospectus, including under “Risk Factors,” when reviewing such statement. We believe that these factors include, but are not limited to:

The factors identified above should not be construed as an exhaustive list of factors that could affect our future results, and should be read in conjunction with the other cautionary statements that are included elsewhere in this prospectus. The forward-looking statements made in this prospectus are made only as of the date of this prospectus. The forward-looking statements made in documents incorporated by reference into this prospectus are made only as of the date of such documents. The forward-looking statements made in any accompanying prospectus supplement are made only as of the date of such document. We do not undertake any obligation to publicly update or review any forward-looking statement except as required by law, whether as a result of new information, future developments or otherwise. If we do update one or more forward-looking statements, no inference should be made that we will make additional updates with respect to those or other forward-looking statements.

If one or more of these or other risks or uncertainties materialize, or if our underlying assumptions prove to be incorrect, our actual results may vary materially from what we may have expressed or implied by these forward-looking statements. We caution that you should not place undue reliance on any of our forward-looking statements. You should specifically consider the factors identified in this prospectus that could cause actual results to differ before making an investment decision to purchase our securities. Furthermore, new risks and uncertainties arise from time to time, and it is impossible for us to predict those events or how they may affect us.

Unless we inform you otherwise in a prospectus supplement or free writing prospectus, we intend to use the net proceeds from the sale of securities we are offering for general corporate purposes. This may include, among other things, additions to working capital, repayment or refinancing of existing indebtedness or other corporate obligations, financing of capital expenditures and acquisitions and investment in existing and future projects.

As used in this prospectus, “debt securities” means the debentures, notes, bonds and other evidences of indebtedness that International Seaways, Inc. may issue from time to time. Debt securities offered by this prospectus will be either senior debt securities or subordinated debt securities. Senior debt securities will be issued under a “Senior Indenture” between us and the Bank of New York Mellon, as trustee, dated May 31, 2018 and subordinated debt securities will be issued under a “Subordinated Indenture” to be entered into later. This prospectus sometimes refers to the Senior Indenture and the Subordinated Indenture collectively as the “Indentures.” Unless the applicable prospectus supplement states otherwise, the trustee under each of the Senior Indenture and the Subordinated Indenture will be The Bank of New York Mellon.

The form of Senior Indenture and the form of the Subordinated Indenture are filed as exhibits to the registration statement. The statements and descriptions in this prospectus or in any prospectus supplement regarding provisions of the Indentures and debt securities are summaries thereof, do not purport to be complete and are subject to, and are qualified in their entirety by reference to, all of the provisions of the Indentures and debt securities, including the definitions therein of certain terms.

Debt securities will be direct unsecured obligations of International Seaways, Inc. Senior debt securities will rank equally with all of International Seaways, Inc.’s other senior and unsubordinated debt. The subordinated debt securities will be subordinate and junior in right of payment to all of International Seaways, Inc.’s present and future senior indebtedness.

Because International Seaways, Inc. is principally a holding company, its right to participate in any distribution of assets of any subsidiary, upon the subsidiary’s liquidation or reorganization or otherwise, is subject to the prior claims of creditors of the subsidiary, except to the extent International Seaways, Inc. may be recognized as a creditor of that subsidiary. Accordingly, International Seaways, Inc.’s obligations under debt securities will be structurally subordinated to all existing and future indebtedness and liabilities of its subsidiaries, and holders of debt securities should look only to International Seaways, Inc.’s assets for payment thereunder.

The Indentures do not limit the aggregate principal amount of debt securities that International Seaways, Inc. may issue and provide that International Seaways, Inc. may issue debt securities from time to time in one or more series, in each case with the same or various maturities, at par or at a discount. International Seaways, Inc. may issue additional debt securities of a particular series without the consent of the holders of debt securities of such series outstanding at the time of the issuance. Any such additional debt securities, together with all other outstanding debt securities of that series, will constitute a single series of debt securities under the applicable Indenture. The Indentures also do not limit our ability to incur other debt, except as described under “Restrictive Covenants” herein.

Each prospectus supplement will describe the terms relating to the specific series of debt securities being offered. These terms will include some or all of the following:

Unless otherwise specified in the applicable prospectus supplement, debt securities will be issued in fully-registered form without coupons.

Unless otherwise specified in the applicable prospectus supplement, debt securities will not be listed on any securities exchange.

Debt securities may be sold at a substantial discount below their stated principal amount, bearing no interest or interest at a rate which at the time of issuance is below market rates. The applicable prospectus supplement will describe the federal income tax consequences and special considerations applicable to any such debt securities. Debt securities may also be issued as indexed securities or securities denominated in foreign currencies, currency units or composite currencies, as described in more detail in the prospectus supplement relating to any of the particular debt securities. The prospectus supplement relating to specific debt securities will also describe any special considerations and certain additional tax considerations applicable to such debt securities.

The prospectus supplement relating to any offering of subordinated debt securities will describe the specific subordination provisions. However, unless otherwise noted in the applicable prospectus supplement, subordinated debt securities will be subordinate and junior in right of payment to all of International Seaways, Inc.’s Senior Indebtedness, to the extent and in the manner set forth in the Subordinated Indenture.

Under the Subordinated Indenture, “Senior Indebtedness” means all obligations of International Seaways, Inc. in respect of any of the following, whether outstanding at the date of execution of the Subordinated Indenture or thereafter incurred or created:

Senior Indebtedness shall continue to be Senior Indebtedness and be entitled to the benefits of the subordination provisions irrespective of any amendment, modification or waiver of any term of such Senior Indebtedness.

Unless otherwise noted in the accompanying prospectus supplement, if International Seaways, Inc. defaults in the payment of any principal of (or premium, if any) or interest on any Senior Indebtedness when it becomes due and payable, whether at maturity or at a date fixed for prepayment or by declaration or otherwise, then, unless and until such default is cured or waived or ceases to exist, International Seaways, Inc. will make no direct or indirect payment (in cash, property, securities, by set-off or otherwise) in respect of the principal of or interest on the subordinated debt securities or in respect of any redemption, retirement, purchase or other requisition of any of the subordinated debt securities.

In the event of the acceleration of the maturity of any subordinated debt securities, the holders of all senior debt securities outstanding at the time of such acceleration will first be entitled to receive payment in full of all amounts due on senior debt securities before the holders of subordinated debt securities will be entitled to receive any payment of principal (and premium, if any) or interest on the subordinated debt securities.

If any of the following events occur, International Seaways, Inc. will pay in full all Senior Indebtedness before it makes any payment or distribution under subordinated debt securities, whether in cash, securities or other property, to any holder of subordinated debt securities:

In such event, any payment or distribution under subordinated debt securities, whether in cash, securities or other property, which would otherwise (but for the subordination provisions) be payable or deliverable in respect of such subordinated debt securities, will be paid or delivered directly to the holders of Senior Indebtedness in accordance with the priorities then existing among such holders until all Senior Indebtedness has been paid in full. If any payment or distribution under subordinated debt securities is received by the trustee of any subordinated debt securities in contravention of any of the terms of the Subordinated Indenture and before all the Senior Indebtedness has been paid in full, such payment or distribution or security will be received in trust for the benefit of, and paid over or delivered and transferred to, the holders of Senior Indebtedness at the time outstanding in accordance with the priorities then existing among such holders for application to the payment of all Senior Indebtedness remaining unpaid to the extent necessary to pay all such Senior Indebtedness in full.

The Subordinated Indenture does not limit the issuance of additional Senior Indebtedness.

If subordinated debt securities are issued to a trust in connection with the issuance of trust preferred securities, such subordinated debt securities may thereafter be distributed pro rata to the holders of such trust securities in connection with the dissolution of such trust upon the occurrence of certain events described in the applicable prospectus supplement.

In the case of debt securities that are convertible into other securities, an accompanying prospectus supplement will set forth the terms on which such securities are convertible into shares of common stock, shares of preferred stock or other securities. Those terms will address whether conversion is mandatory, at the option of the holder or at our option. The terms may also provide that the number of shares or interests of our shares of common stock or other securities, as the case may be, to be received by the holders of the convertible debt securities will be calculated according to the market price of our shares of common stock or other securities, as the case may be, as of a time stated in the prospectus supplement or otherwise.

Unless an accompanying prospectus supplement states otherwise, the following shall constitute “Events of Default” under the Indentures with respect to each series of debt securities:

If an Event of Default with respect to any debt securities of any series outstanding under either of the Indentures shall occur and be continuing, the trustee under such Indenture or the holders of at least 25% in aggregate principal amount of the debt securities of that series outstanding may declare, by notice as provided in the applicable Indenture, the principal amount (or such lesser amount as may be provided for in the debt securities of that series) of the debt securities of that series outstanding to be due and payable immediately; provided that, in the case of an Event of Default involving certain events in bankruptcy, insolvency or reorganization, acceleration is automatic; and, provided further, that after such acceleration, but before a judgment or decree based on acceleration, the holders of a majority in aggregate principal amount of the outstanding debt securities of that series may, under certain circumstances, rescind and annul such acceleration if all Events of Default, other than the nonpayment of accelerated principal, have been cured or waived.

Upon the acceleration of the maturity of original issue discount securities, an amount less than the principal amount thereof will become due and payable.

Reference is made to the prospectus supplement relating to any original issue discount securities for the particular provisions relating to acceleration of maturity thereof. Any past default under either Indenture with respect to debt securities of any series, and any Event of Default arising therefrom, may be waived by the holders of a majority in principal amount of all debt securities of such series outstanding under such Indenture, except in the case of (i) default in the payment of the principal of (or premium, if any) or interest on any debt securities of such series or (ii) default in respect of a covenant or provision which may not be amended or modified without the consent of the holder of each outstanding debt security of such series affected.

The trustee is required, within 90 days after the occurrence of a default (which is known to the trustee and is continuing), with respect to the debt securities of any series (without regard to any grace period or notice requirements), to give to the holders of debt securities of such series notice of such default; provided, however, that, except in the case of a default in the payment of the principal of (and premium, if any) or interest, or in the payment of any sinking fund installment, on any debt securities of such series, the trustee shall be protected in withholding such notice if it in good faith determines that the withholding of such notice is in the interests of the holders of debt securities of such series.

The trustee, subject to its duties during default to act with the required standard of care, may require indemnification by the holders of debt securities of any series with respect to which a default has occurred before proceeding to exercise any right or power under the Indentures at the request of the holders of debt securities of such series. Subject to such right of indemnification and to certain other limitations, the holders of a majority in principal amount of the outstanding debt securities of any series under either Indenture 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 with respect to debt securities of such series.

No holder of a debt security of any series may institute any action against International Seaways, Inc. under either of the Indentures (except actions for payment of overdue principal of (and premium, if any) or interest on such debt security or for the conversion or exchange of such debt security in accordance with its terms) unless (i) the holder has given to the trustee written notice of an Event of Default and of the continuance thereof with respect to debt securities of such series specifying an Event of Default, as required under the applicable Indenture, (ii) the holders of at least 25% in aggregate principal amount of debt securities of that series then outstanding under such Indenture shall have requested the trustee to institute such action and offered to the trustee indemnity reasonably satisfactory to it against the costs, expenses and liabilities to be incurred in compliance with such request and (iii) the trustee shall not have instituted such action within 60 days of such request.

The terms of the Indentures require that International Seaways, Inc. furnish annually to the trustee statements as to its compliance with all conditions and covenants under each Indenture.

If indicated in the applicable prospectus supplement, International Seaways, Inc. may discharge or defease its obligations under each Indenture as set forth below.

International Seaways, Inc. may discharge certain obligations to holders of any series of debt securities issued under either the Senior Indenture or the Subordinated Indenture which have not already been delivered to the trustee for cancellation and which have either become due and payable or are by their terms due and payable within one year (or scheduled for redemption within one year) by irrevocably depositing with the trustee cash or, in the case of debt securities payable only in U.S. dollars, U.S. Government Obligations (as defined in either Indenture), as trust funds in an amount certified to be sufficient to pay when due, whether at maturity, upon redemption or otherwise, the principal of (and premium, if any) and interest on such debt securities.

If indicated in the applicable prospectus supplement, International Seaways, Inc. may elect either (i) to defease and be discharged from any and all obligations with respect to debt securities of or within any series (except as otherwise provided in the relevant Indenture) (“defeasance”) or (ii) to be released from its obligations with respect to certain covenants applicable to debt securities of or within any series (“covenant defeasance”), upon the deposit with the relevant Indenture trustee, in trust for such purpose, of money and/or government obligations which through the payment of principal and interest in accordance with their terms will provide money in an amount sufficient, without reinvestment, to pay the principal of (and premium, if any) or interest on such debt securities to maturity or redemption, as the case may be, and any mandatory sinking fund or analogous payments thereon. As a condition to defeasance or covenant defeasance, International Seaways, Inc. must deliver to the trustee an opinion of counsel to the effect that the holders of such debt securities will not recognize income, gain or loss for federal income tax purposes as a result of such defeasance or covenant defeasance and will be subject to federal income tax on the same amounts and in the same manner and at the same times as would have been the case if such defeasance or covenant defeasance had not occurred. Such opinion of counsel, in the case of defeasance under clause (i) above, must refer to and be based upon a ruling of the Internal Revenue Service or a change in applicable federal income tax law occurring after the date of the relevant Indenture. In addition, in the case of either defeasance or covenant defeasance, International Seaways, Inc. shall have delivered to the trustee (i) an officers’ certificate to the effect that the relevant debt securities exchange(s) have informed it that neither such debt securities nor any other debt securities of the same series, if then listed on any securities exchange, will be delisted as a result of such deposit and (ii) an officers’ certificate and an opinion of counsel, each stating that all conditions precedent with respect to such defeasance or covenant defeasance have been complied with. International Seaways, Inc. may exercise its defeasance option with respect to such debt securities notwithstanding its prior exercise of its covenant defeasance option.

Under the Indentures, International Seaways, Inc. and the applicable trustee may supplement the Indentures for certain purposes which would not materially adversely affect the interests or rights of the holders of debt securities of a series without the consent of those holders. International Seaways, Inc. and the applicable trustee may also modify the Indentures or any supplemental indenture in a manner that affects the interests or rights of the holders of debt securities with the consent of the holders of at least a majority in aggregate principal amount of the outstanding debt securities of each affected series issued under the Indenture. However, the Indentures require the consent of each holder of debt securities that would be affected by any modification which would:

If subordinated debt securities are held by a trust or a trustee of a trust, a supplemental indenture that affects the interests or rights of the holders of debt securities will not be effective until the holders of not less than a majority in liquidation preference of the preferred securities and common securities of the applicable trust, collectively, have consented to the supplemental indenture; provided, further, that if the consent of the holder of each outstanding debt security is required, the supplemental indenture will not be effective until each holder of the preferred securities and the common securities of the applicable trust has consented to the supplemental indenture.

The Indentures permit the holders of at least a majority in aggregate principal amount of the outstanding debt securities of any series issued under the Indentures which is affected by the modification or amendment to waive International Seaways, Inc.’s compliance with certain covenants contained in the Indentures.

Unless otherwise indicated in the applicable prospectus supplement, payment of interest on a debt security on any interest payment date will be made to the person in whose name a debt security is registered at the close of business on the record date for the interest.

Unless otherwise indicated in the applicable prospectus supplement, principal, interest and premium on the debt securities of a particular series will be payable at the office of such paying agent or paying agents as International Seaways, Inc. may designate for such purpose from time to time.

Notwithstanding the foregoing, at International Seaways, Inc.’s option, payment of any interest may be made by check mailed to the address of the person entitled thereto as such address appears in the security register.

Unless otherwise indicated in the applicable prospectus supplement, a paying agent designated by International Seaways, Inc. and located in the Borough of Manhattan, The City of New York will act as paying agent for payments with respect to debt securities of each series. All paying agents initially designated by International Seaways, Inc. for debt securities of a particular series will be named in the applicable prospectus supplement. International Seaways, Inc. may at any time designate additional paying agents or rescind the designation of any paying agent or approve a change in the office through which any paying agent acts, except that International Seaways, Inc. will be required to maintain a paying agent in each place of payment for debt securities of a particular series.

All moneys paid by International Seaways, Inc. to a paying agent for the payment of the principal, interest or premium on any debt security which remain unclaimed at the end of two years after such principal, interest or premium has become due and payable will be repaid to International Seaways, Inc. upon request, and the holder of such debt security thereafter may look only to International Seaways, Inc. for payment thereof.

Unless an accompanying prospectus supplement states otherwise, debt securities will be represented by one or more global certificates registered in the name of a nominee for The Depository Trust Company, or DTC. In such case, each holder’s beneficial interest in the global securities will be shown on the records of DTC and transfers of beneficial interests will only be effected through DTC’s records.

A holder of debt securities may only exchange a beneficial interest in a global security for certificated securities registered in the holder’s name if:

If debt securities are issued in certificated form, they will only be issued in the minimum denomination specified in the accompanying prospectus supplement and integral multiples of such denomination. Transfers and exchanges of such debt securities will only be permitted in such minimum denomination. Transfers of debt securities in certificated form may be registered at the trustee’s corporate office or at the offices of any paying agent or trustee appointed by International Seaways, Inc. under the Indentures. Exchanges of debt securities for an equal aggregate principal amount of debt securities in different denominations may also be made at such locations.

The Senior Indenture, the Subordinated Indenture and debt securities will be governed by, and construed in accordance with, the internal laws of the State of New York, without regard to its principles of conflicts of laws.

Unless the applicable prospectus supplement states otherwise, the trustee under the Senior Indenture is, and the trustee under the Subordinated Indenture is, The Bank of New York Mellon. We and our subsidiaries maintain ordinary banking and trust relationships with a number of banks and trust companies.

International Seaways, Inc.’s Amended and Restated Articles of Incorporation authorizes our board of directors (the “board”) or a committee of the board to cause preferred stock to be issued in one or more series, without stockholder action. We are authorized to issue up to 10,000,000 shares of preferred stock, without par value, and can determine the number of shares of each series, and the rights, preferences and limitations of each series. We may amend the Amended and Restated Articles of Incorporation to increase the number of authorized shares of preferred stock in a manner permitted by the Amended and Restated Articles of Incorporation and Marshall Islands law. As of the date of this prospectus, there is no preferred stock outstanding.

The particular terms of any series of preferred stock offered by us will be described in the prospectus supplement relating to that series of preferred stock. Those terms relating to the series of preferred stock offered may include:

The following summary is not complete. You should refer to the certificate of designations relating to any series of preferred stock for the complete terms of that preferred stock. The certificate of designations will be filed with the SEC at the time of the offering of the preferred stock. Unless otherwise specified in the applicable prospectus supplement, if we liquidate, dissolve or wind-up our business, each series of preferred stock will have the same rank as to dividends and distributions as each other series of preferred stock we may issue in the future. Preferred stock will have no preemptive rights.

Holders of preferred stock will be entitled to receive, when, as and if declared by our board, cash dividends at the rates and on the dates set forth in the related prospectus supplement. Dividend rates may be fixed or variable or both. Different series of preferred stock may be entitled to dividends at different dividend rates or based upon different methods of determination. Each dividend will be payable to the holders of record as they appear on our stock books on record dates determined by our board. Dividends on preferred stock may be cumulative or noncumulative, as specified in the related prospectus supplement. If our board fails to declare a dividend on any preferred stock for which dividends are noncumulative, then the right to receive that dividend will be lost, and we will have no obligation to pay the dividend for that dividend period, whether or not dividends are declared for any future dividend period.

No full dividends will be declared or paid on any preferred stock unless full dividends for the dividend period commencing after the immediately preceding dividend payment date and any cumulative dividends still owing have been or contemporaneously are declared and paid on all other series of preferred stock which have the same rank as, or rank senior to, that series of preferred stock. When those dividends are not paid in full, dividends will be declared pro rata, so that the amount of dividends declared per share on that series of preferred stock and on each other series of preferred stock having the same rank as that series of preferred stock will bear the same ratio to each other that accrued dividends per share on that series of preferred stock and the other series of preferred stock bear to each other. In addition, generally, unless full dividends including any cumulative dividends still owing on all outstanding shares of any series of preferred stock have been paid, no dividends will be declared or paid on the common stock and generally we may not redeem or purchase any common stock. No interest will be paid in connection with any dividend payment or payments which may be in arrears.

Unless otherwise set forth in the related prospectus supplement, the dividends payable for each dividend period will be computed by annualizing the applicable dividend rate and dividing by the number of dividend periods in a year, except that the amount of dividends payable for the initial dividend period or any period shorter than a full dividend period will be computed on the basis of a 360-day year consisting of twelve 30-day months and, for any period less than a full month, the actual number of days elapsed in the period.

If we liquidate, dissolve or wind-up our affairs, either voluntarily or involuntarily, the holders of each series of preferred stock will be entitled to receive liquidating distributions in the amount set forth in the prospectus supplement relating to the series of preferred stock, plus an amount equal to any accrued and unpaid dividends before any distribution of assets is made to the holders of common stock. If the amounts payable with respect to preferred stock of any series and any stock having the same rank as that series of preferred stock are not paid in full, the holders of the preferred stock will share ratably in any such distribution of assets in proportion to the full respective preferential amounts to which they are entitled. After the holders of each series of preferred stock having the same rank are paid in full, they will have no right or claim to any of our remaining assets. Neither the sale of all or substantially all of our property or business nor a merger or consolidation by us with any other corporation will be considered a dissolution, liquidation or winding up by us of our business or affairs.

Any series of preferred stock may be redeemable in whole or in part at our option. In addition, any series of preferred stock may be subject to mandatory redemption pursuant to a sinking fund. The redemption provisions that may apply to a series of preferred stock, including the redemption dates and the redemption prices for that series, will be set forth in the related prospectus supplement.

If a series of preferred stock is subject to mandatory redemption, the related prospectus supplement will specify the year we can begin to redeem shares of the preferred stock, the number of shares of the preferred stock we can redeem each year, and the redemption price per share. We may pay the redemption price in cash, stock or other securities of INSW or of third parties, as specified in the related prospectus supplement.

If fewer than all the outstanding shares of any series of preferred stock are to be redeemed, whether by mandatory or optional redemption, the board will determine the method for selecting the shares to be redeemed, which may be by lot or pro rata by any other method determined to be equitable. From and after the redemption date, dividends will cease to accrue on the shares of preferred stock called for redemption and all rights of the holders of those shares other than the right to receive the redemption price will cease.

The related prospectus supplement will state any conversion rights under which shares of preferred stock are convertible into shares of common stock or another series of preferred stock or debt securities.

For most series of preferred stock, the holders of preferred stock will generally not be entitled to vote. Except as indicated in the related prospectus supplement, if we issue full shares of any series of preferred stock, each share will be entitled to one vote on matters on which holders of that series of preferred stock are entitled to vote. Because each full share of any series of preferred stock will be entitled to one vote, the voting power of that series will depend on the number of shares in that series, and not on the aggregate liquidation preference or initial offering price of the shares of that series of preferred stock.

We will appoint a transfer agent, registrar and dividend disbursement agent for the preferred stock. The registrar for the preferred stock will send notices to the holders of the preferred stock of any meeting at which those holders will have the right to elect directors or to vote on any other matter.

A series of preferred stock may be issued in whole or in part in the form of one or more global securities that will be deposited with a depositary or its nominee identified in the related prospectus supplement. For most series of preferred stock, the depositary will be DTC (as defined herein). A global security may not be transferred except as a whole to the depositary, a nominee of the depositary or their successors unless it is exchanged in whole or in part for preferred stock in individually certificated form. For a description of the depositary arrangements, see “Book-Entry Issuance.” Any additional terms of the depositary arrangement with respect to any series of preferred stock and the rights of and limitations on owners of beneficial interests in a global security representing a series of preferred stock may be described in the related prospectus supplement.

The following descriptions are summaries of the material terms of our capital stock, articles of incorporation and by-laws, each as amended and restated, and any references to Republic of the Marshall Islands (the “RMI”) law are not meant to be complete and are subject to, and qualified in their entirety by, reference to our amended and restated articles of incorporation (“Amended and Restated Articles of Incorporation”), a copy of which has been filed as an exhibit to our Current Report on Form 8-K dated December 2, 2016 and is incorporated by reference into the registration statement of which this prospectus forms a part, our amended and restated by-laws (“Amended and Restated By-Laws”), a copy of which has been filed as an exhibit to our Current Report on Form 8-K dated December 2, 2016 and is incorporated by reference into the registration statement of which this prospectus forms a part, and to the RMI Business Corporations Act (the “BCA”). See “Where You Can Find More Information.” These descriptions may not contain all of the information that may be important to you and should be read in conjunction with our Amended and Restated Articles of Incorporation, Amended and Restated By-Laws and applicable provisions of the BCA.

Our authorized capital stock consists of (a) 100,000,000 authorized shares of common stock, no par value (the “common stock”), and (b) 10,000,000 shares of preferred stock, no par value (the “preferred stock”).

As of December 17, 2025 there were 49,404,078 shares of common stock outstanding and no shares of preferred stock outstanding.

The holders of our common stock are entitled to such dividends as our board of directors may declare from time to time from legally available funds, based on the number of shares of common stock then held of record by such holder, subject to the preferential rights of the holders of any shares of preferred stock that we may issue in the future. The holders of our common stock are entitled to one vote per share.

Our Amended and Restated Articles of Incorporation do not provide for cumulative voting in the election of directors, which means that the holders of a majority of the outstanding shares of common stock can elect all of the directors standing for election, and the holders of the remaining shares are not able to elect any directors. Our Amended and Restated By-Laws provide that directors will be elected by a majority of the shares voting once a quorum is present.

Upon any voluntary or involuntary liquidation, dissolution or winding up of our affairs, the holders of our common stock are entitled to share, on a pro rata basis, all assets remaining after payment to claimants and creditors and subject to prior distribution rights of any shares of preferred stock that we may issue in the future. All of the outstanding shares of common stock are fully paid and non-assessable. Holders of our common stock have no preemptive rights, conversion rights or other subscription rights as set out in our Amended and Restated Articles of Incorporation, and there are no redemption or sinking fund provisions applicable to our common stock. The rights, preferences and privileges of holders of common stock are subject to, and may be impacted by, the rights of the holders of shares of any series of preferred stock that we may designate and issue in the future.

As of December 17, 2025, there were approximately 54 holders of record of our common stock, including Cede & Co. as nominee for DTC.

The terms pursuant to which we may issue preferred stock are described above under “Description of Preferred Stock.” Preferred stock could have voting or conversion rights that could adversely affect the voting power or other rights of holders of our common stock and the issuance of preferred stock could also have the effect, under certain circumstances, of delaying, deferring or preventing a change of control of us.

On May 8, 2022, we entered into a shareholder rights plan in the form of a Rights Agreement (the “Rights Agreement”), dated as of May 8, 2022, between the us and Computershare Trust Company, N.A., as rights agent. The Rights Agreement was approved by our board of directors. In connection with the Rights Agreement, our board authorized and declared a dividend distribution of one Right for each outstanding share of Common Stock. The dividend was payable on May 19, 2022 to stockholders of record at the close of business on such date. While the Rights Agreement was effective immediately, the Rights would become exercisable only if a person or group acquired beneficial ownership, as defined in the Rights Agreement, of 17.5% or more of the Common Stock in a transaction not approved by our board. In that situation, each holder of a Right (other than the acquiring person or group) would have the right to purchase, upon payment of the then-current exercise price, a number of shares of Common Stock having a market value of twice the exercise price of the Right. In addition, at any time after a person or group acquired 17.5% or more of the Common Stock (unless such person or group acquires 50% or more), the board could exchange one share of the Common Stock for each outstanding Right (other than Rights owned by such person or group, which would have become null and void). The expiry date of the Rights Agreement was May 7, 2023.

On April 11, 2023, our board approved the A&R Rights Agreement, which amended and restated the Rights Agreement dated as of May 8, 2022. The A&R Rights Agreement implements substantially the same features and protective measures of the Rights Agreements and includes the following revised or additional provisions:

The board adopted the Rights Agreement and the A&R Rights Agreement to enable all stockholders of the Company to realize the full potential value of their investment in the Company. The A&R Rights Agreement is designed to prevent any individual stockholder or group of stockholders from gaining control of the Company through open market accumulation without paying a control premium to all stockholders or by otherwise disadvantaging other stockholders. The A&R Rights Agreement is not intended to prevent a takeover or deter fair offers for securities of the Company that deliver value to all stockholders on an equal basis. It is designed, instead, to encourage anyone seeking to acquire the Company to negotiate with our board prior to attempting a takeover.

The board may consider an earlier termination of the A&R Rights Agreement if market and other conditions warrant.

Anti-Takeover Effects of Provisions of our Amended and Restated Articles of Incorporation, our Amended and Restated By-Laws and RMI Law

Our Amended and Restated Articles of Incorporation and Amended and Restated By-Laws contain a number of provisions relating to corporate governance and to the rights of stockholders. Certain of these provisions may be deemed to have a potential “anti-takeover” effect in that such provisions may delay, defer or prevent a change of control or an unsolicited acquisition proposal that a stockholder might consider favorable, including a proposal that might result in the payment of a premium over the market price for the shares held by the stockholders. Examples of such provisions in our Amended and Restated Articles of Incorporation and Amended and Restated By-Laws relating to corporate governance and the rights of stockholders, certain of which may be deemed to have a potential “anti-takeover” effect include:

Authorized but Unissued or Undesignated Capital Stock. Our authorized capital stock consists of 100,000,000 authorized shares of common stock and 10,000,000 shares of preferred stock. A large quantity of authorized but unissued shares may deter potential takeover attempts because of the ability of our board to authorize the issuance of some or all of these shares to a friendly party, or to the public, which would make it more difficult for a potential acquirer to obtain control of us. This possibility may encourage persons seeking to acquire control of us to negotiate first with our board. The authorized but unissued stock may be issued by our board in one or more transactions. In this regard, our Amended and Restated Articles of Incorporation grants the board of directors broad power to establish the rights and preferences of authorized and unissued preferred stock. Although our Amended and Restated Articles of Incorporation prohibits the board, without the affirmative vote of at least a majority of the total voting power of our outstanding shares of capital stock entitled to vote on such matters, voting as a class, from issuing any preferred stock for any defensive or anti-takeover purpose, for the purpose of implementing any shareholder rights plan or with features specifically intended to make any attempted acquisition of the Corporation more difficult or costly, the issuance of shares of preferred stock pursuant to the board’s authority described above could decrease the amount of earnings and assets available for distribution to holders of common stock and adversely affect the rights and powers, including voting rights, of such holders and may have the effect of delaying, deferring or preventing a change of control. The board does not currently intend to seek stockholder approval prior to any issuance of preferred stock, unless otherwise required by law or our Amended and Restated Articles of Incorporation.

Action by Written Consent. Our Amended and Restated By-Laws and Section 67 of the BCA provide that stockholder action can be taken by written consent in lieu of a meeting if all stockholders entitled to vote on the subject matter unanimously consent.

Special Meetings of Stockholders. Our Amended and Restated By-Laws provide that special meetings of our stockholders may be called only by the President or any Vice President, by resolution of the board or by holders of not less than 25% of all outstanding shares entitled to vote on the matter for which the meeting is called. Our Amended and Restated By-Laws prohibit the conduct of any business at a special meeting other than as specified in the notice for such meeting.

Advance Notice Procedures. Our Amended and Restated By-Laws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of the board. In order for any matter to be “properly brought” before a meeting, a stockholder will have to comply with advance notice requirements and provide us with certain information. Generally, to be timely, a stockholder’s notice must be received at our principal executive offices not less than 60 days nor more than 90 days prior to the first anniversary of the date of the immediately preceding annual meeting. In the event that the date of the annual meeting is more than 30 days earlier or more than 60 days later than such anniversary date, notice by the stockholder must be received no earlier than 90 days prior to the annual meeting and not later than the later of 60 days prior to the annual meeting or 10 days following the public announcement of the date of the annual meeting. Our Amended and Restated By-Laws also specify requirements as to the form and content of a stockholder’s notice. These provisions may defer, delay or discourage a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to influence or obtain control of us.

Super Majority Approval Requirements. Our Amended and Restated By-Laws provide that our board, at any regular meeting or special meeting called for the purpose, and our stockholders, at any annual meeting or special meeting called for the purpose, may make, alter, amend or repeal our Amended and Restated By-Laws. However, our board may not, without the affirmative vote of a majority of the outstanding stock entitled to vote on such matters, alter, amend or repeal certain provisions of our Amended and Restated By-Laws, including those relating to stockholder meeting quorum requirements, majority election of directors, notification of the nominations for the election of directors, special meetings of our board, committees of the board and amendments to the Amended and Restated By-Laws. Further, our board may not, without the affirmative vote of the holders of two-thirds or more of the outstanding stock entitled to vote on such matters, alter, amend or repeal certain other provisions of our Amended and Restated By-Laws, including those relating to the calling of special meetings by stockholders and stockholder action by written consent.

The BCA provides generally that the affirmative vote of a majority of the outstanding shares then entitled to vote is required to amend a corporation’s articles of incorporation, unless the articles of incorporation requires a greater percentage. Our Amended and Restated Articles of Incorporation provides that specified provisions, including those relating to amendment of our Amended and Restated Articles of Incorporation and the procedures by which any action required or permitted to be taken by holders of common stock may be performed, may only be amended or repealed by the affirmative vote of two-thirds (2/3) of the combined voting power of the outstanding shares of our capital stock.

The combination of these provisions may make it more difficult for our existing stockholders to replace our board as well as for another party to obtain control of us by replacing our board of directors. Because our board has the power to retain or discharge our officers, these provisions could also make it more difficult for existing stockholders or another party to effect a change in management.

Our Amended and Restated By-Laws provide that unless we consent in writing to the selection of an alternate forum, the State and Federal Court located in the State of Delaware is the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of fiduciary duty owed by any of our directors, officers or other employees, (iii) any action asserting a claim against us arising pursuant to the BCA or (iv) any action asserting a claim against us that is governed by the bylaws, in all cases subject to the court having personal jurisdiction over the parties named as defendants. Any person or entity purchasing or otherwise acquiring any interest in our shares of common stock shall be deemed to have notice of and consented to the forum provisions in our Amended and Restated By-Laws.

Under the BCA, with certain exceptions, our stockholders will have appraisal rights in connection with a merger or consolidation of us. Pursuant to the BCA, stockholders who properly request and perfect appraisal rights in connection with such merger or consolidation will have the right to receive payment of the fair value of their shares as determined by the appropriate court. See “Description of Capital Stock—Exclusive Forum” above.

Under the BCA, any of our stockholders may bring an action in our name to procure a judgment in our favor, also known as a derivative action, provided that the stockholder bringing the action is a holder of our shares at the time of the transaction to which the action relates or such stockholder’s stock thereafter devolved by operation of law.

Under the BCA, a Marshall Islands corporation shall have the power to indemnify any person who was or is a party or is threatened to be made a party to or a witness in or is otherwise involved in any threatened, pending or completed action, suit, claim, inquiry or proceeding whether civil, criminal, administrative or investigative (including an action by or in the right of the corporation) and whether formal or informal, by reason of the fact that he or she, or a person for whom he or she is the legal representative, is or was a director or officer of the corporation, or, while a director or officer of the corporation, is or was serving at the request of the corporation as a director, officer, employee, trustee or agent of another corporation, partnership, joint venture, trust, nonprofit 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 him or her in connection with such action, suit or proceeding. The corporation shall be required to indemnify or advance expenses to such a person in connection with a proceeding commenced by the person against the corporation only if the commencement of such proceeding was authorized in the specific case by our board or was brought to establish or enforce a right to indemnification under the bylaws, the corporation’s articles of incorporation, any agreement, the laws of the RMI or otherwise.

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, he or she shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by him or her 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 our board in the specific case upon receipt of an undertaking by or on behalf of the director or officer to repay such amount unless it shall ultimately be determined that he or she is entitled to be indemnified by the corporation as authorized in the BCA.

In addition, a Marshall Islands corporation has the power 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 him or her and incurred by him or her in such capacity whether or not the corporation would have the power to indemnify him or her against such liability under the provisions of the BCA. The indemnification provisions of the BCA are not exclusive of any other rights under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise.

Our Amended and Restated Articles of Incorporation limits the liability of our directors to the fullest extent permitted by the BCA and requires that we will provide them with customary indemnification.

The transfer agent and registrar for our common stock is Computershare Trust Company, N.A.

The following is a general description of the terms of the warrants we may issue from time to time. The specific terms of any warrants we offer will be described in the prospectus supplement relating to such warrants.

We may issue warrants to purchase shares of common stock, shares of our preferred stock, our debt securities or any combination thereof. Such warrants may be issued independently or together with any such securities and may be attached or separate from such securities. We will issue each series of warrants under a separate warrant agreement to be entered into between us and a warrant agent. The warrant agent will act solely as our agent and will not assume any obligation or relationship of agency for or with holders or beneficial owners of warrants.

A prospectus supplement will describe the particular terms of any series of warrants we may issue, including the following:

We and the warrant agent may amend or supplement the warrant agreement for a series of warrants without the consent of the holders of the warrants issued thereunder to effect changes that are not inconsistent with the provisions of the warrants and that do not materially and adversely affect the interests of the holders of the warrants.

We may issue units composed of any combination of our shares of common stock, shares of preferred stock, debt securities, convertible debt securities or warrants. We will issue each unit so that the holder of the unit is also the holder of each security included in the unit. As a result, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately at any time or at any time before a specified date.

The following description is a summary of selected provisions relating to units that we may offer. The summary is not complete. When units are offered in the future, a prospectus supplement will describe the particular terms of those securities and the extent to which these general provisions may apply. The specific terms of the units as described in a prospectus supplement will supplement and, if applicable, may modify or replace the general terms described in this section.

This summary and any description of units in the applicable prospectus supplement, information incorporated by reference or free writing prospectus is subject to and is qualified in its entirety by reference to the unit agreement, collateral arrangements and depositary arrangements, if applicable. We will incorporate those documents by reference into via any applicable prospectus supplement.

The applicable provisions described in this section, as well as those described under “Description of Debt Securities,” “Description of Preferred Stock,” “Description of Common Stock,” and “Description of Warrants,” will apply to each unit and to each security included in each unit, respectively.

We may offer and sell all or a portion of the securities covered by this prospectus from time to time, together or separately, in one or more or any combination of the following transactions:

We may sell the securities at prices then prevailing, related to the then-prevailing market price or at negotiated prices. The offering price of the securities from time to time will be determined by us, and, at the time of the determination, may be higher or lower than the market price of our securities on the NYSE or any other exchange or market.

Securities may be sold directly or through broker-dealers acting as principal or agent, or pursuant to a distribution by one or more underwriters on a firm commitment or best-efforts basis. We may also enter into hedging transactions with broker-dealers. In connection with such transactions, broker-dealers of 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 enter into options 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).

In connection with an underwritten offering, underwriters or agents may receive compensation in the form of discounts, concessions or commissions from purchasers of the offered securities for whom they may act as agents. In addition, underwriters may sell the securities to or through dealers, and those 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, dealers or agents participating in a distribution of the securities may be deemed to be “underwriters” within the meaning of the Securities Act, and any commissions received by broker-dealers may be deemed to be underwriting commissions under the Securities Act.

To facilitate the offering of securities covered by this prospectus, certain persons participating in the offering may engage in transactions that stabilize, maintain or otherwise affect the price of our securities. This may include over-allotments or short sales of our securities, which involve the sale by persons participating in the offering of more securities than we sold to them. In these circumstances, these persons would cover such over-allotments or short positions by making purchases in the open market or by exercising their over-allotment option, if any. In addition, these persons may stabilize or maintain the price of our securities by bidding for or purchasing our securities in the open market or by imposing penalty bids, whereby selling concessions allowed to dealers participating in the offering may be reclaimed if securities sold by them is repurchased in connection with stabilization transactions. The effect of these transactions may be to stabilize or maintain the market price of our securities at a level above that which might otherwise prevail in the open market. These transactions may be discontinued at any time.

We may agree to indemnify an underwriter, broker-dealer or agent against certain liabilities related to the sale of the securities, including liabilities under the Securities Act.

At the time we enter any material arrangement with an underwriter or broker-dealer for the sale of securities through a block trade, special offering, exchange distribution, secondary distribution or a purchase by an underwriter or broker-dealer, we will file a supplement to this prospectus, if required, pursuant to Rule 424(b) under the Securities Act, disclosing certain material information, including:

We are subject to the applicable provisions of the Exchange Act and the rules and regulations under the Exchange Act, including Regulation M. This regulation may limit the timing of purchases and sales of any of the securities offered in this prospectus. The anti-manipulation rules under the Exchange Act may apply to sales of securities in the market and to our activities and those of our affiliates. Furthermore, Regulation M may restrict the ability of any person engaged in the distribution of the securities to engage in market-making activities for the particular securities being distributed for a period of up to five business days before the distribution. The restrictions may affect the marketability of the securities and the ability of any person or entity to engage in market-making activities for the securities.

To the extent required, this prospectus may be amended and/or supplemented from time to time to describe a specific plan of distribution.

In the ordinary course of their business activities, any underwriter, broker-dealer or agent and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers and may at any time hold long and short positions in such securities and instruments. Such investment and securities activities may involve our securities and other instruments. Any underwriter, broker-dealer or agent and their respective affiliates may also engage in transactions with or perform services for us or provide other types of financing to us in the ordinary course of their business.

Unless otherwise indicated in any applicable prospectus supplement, the validity of any preferred stock or common stock offered hereby will be passed upon for us by Reeder & Simpson P.C., a Marshall Islands law firm, and the validity of any debt securities offered hereby will be passed upon for us by Cleary Gottlieb Steen & Hamilton LLP.
