This document is in two parts. The first part is this prospectus supplement, which describes the specific terms of this offering and certain other matters. The second part, the prospectus, gives more general information about securities we may offer from time to time. Generally, when we refer to the “prospectus,” we are referring to both parts of this document combined. You should read both this prospectus supplement and the accompanying prospectus, together with additional information described under the headings “Where You Can Find Additional Information” and “Incorporation by Reference.” To the extent the description of our securities in this prospectus supplement differs from the description of our securities in the accompanying prospectus, you should rely on the information in this prospectus supplement.

You should rely only on the information contained or incorporated by reference into this prospectus supplement and the accompanying prospectus. We have not, and the underwriters have not, authorized anyone to provide you with different information. The distribution of this prospectus and sale of these securities in certain jurisdictions may be restricted by law. Persons in possession of this prospectus supplement or the accompanying prospectus are required to inform themselves about and observe any such restrictions. We are not making an offer to sell these securities in any jurisdiction where the offer or sale is not permitted. You should assume that the information appearing in this prospectus supplement is accurate as of the date on the front cover of this prospectus supplement only. Our business, financial condition, results of operations and prospects may have changed since that date.

PROSPECTUS SUMMARY

This summary highlights information contained elsewhere in this prospectus supplement and the accompanying prospectus and should be read together with the information contained in other parts of this prospectus supplement, the accompanying prospectus and the documents we incorporate by reference, including the risk factors on page S-12 of this prospectus supplement and beginning on page 3 of our Annual Report on Form 20-F filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 14, 2017 (our “Annual Report on Form 20-F”).

Unless we otherwise specify, when used in this prospectus supplement, the terms “Costamare,” the “Company,” “we,” “our” and “us” refer to Costamare Inc. and its subsidiaries and/or any one of them, except that when such terms are used in this prospectus supplement in reference to the common stock, they refer specifically to Costamare Inc.

We use the term “twenty foot equivalent unit,” or “TEU,” the international standard measure of containers, in describing the capacity of our containerships.

Before making your investment decision, you should carefully read the prospectus and the documents referred to in “Where You Can Find Additional Information” and “Incorporation by Reference” for information about us, including our financial statements.

Unless otherwise indicated, all references to currency amounts in this prospectus supplement and the accompanying prospectus are in U.S. dollars.

Unless otherwise indicated, all data regarding our fleet and the terms of our charters is as of May 22, 2017 and references to our fleet at future dates assume there have been no additional acquisitions, including acquisitions pursuant to the Framework Deed dated as of May 15, 2013 and as amended and restated on May 18, 2015 (the “Framework Deed”) between the Company and its wholly-owned subsidiary, Costamare Ventures Inc. (“Costamare Ventures”), on the one hand, and York Capital Management Global Advisors LLC and an affiliated fund (collectively, together with the funds it manages or advises, “York”), on the other, by vessel-owning joint venture entities in which we hold a minority equity interest (any such jointly-owned vessel, including any vessel under construction, referred to as a “Joint Venture vessel”) and no dispositions.

Our Company

We are an international owner of containerships, chartering our vessels to many of the world’s largest liner companies. As of May 22, 2017, we had a fleet of 72 containerships with a total capacity of approximately 473,000 TEU, making us one of the largest public containership companies in the world based on total TEU capacity. At that date, our fleet consisted of (i) 69 vessels in the water, aggregating approximately 454,000 TEU and (ii) three newbuild vessels aggregating approximately 19,000 TEU that are scheduled to be delivered to us through the second quarter of 2018, based on the current shipyard schedule. Eighteen of our containerships, including three newbuilds on order, have been acquired pursuant to the Framework Deed with York by vessel-owning joint venture entities in which we hold a minority equity interest.

Costamare Inc. was incorporated in the Republic of The Marshall Islands on April 21, 2008 under the Marshall Islands Business Corporations Act. We are controlled by members of the Konstantakopoulos family, which has a long history of operating and investing in the international shipping industry, including a long history of vessel ownership. We were founded in 1974 and initially owned and operated drybulk carrier vessels. In 1984 we became the first Greek-owned company to enter the containership market and, since 1992, we have focused exclusively on containerships. After assuming management of our company in 1998, Konstantinos Konstantakopoulos has concentrated on building a large, modern and reliable containership fleet run and supported by highly skilled, experienced and loyal personnel. Under Konstantinos Konstantakopoulos’s leadership, we have continued to foster a company culture focusing on excellent customer service, industry leadership and innovation.

In November 2010, we completed an initial public offering of our common stock in the United States and our common stock began trading on the NYSE on November 4, 2010 under the ticker

S-1

symbol “CMRE.” On March 27, 2012 and October 19, 2012, we completed two follow-on public offerings of our common stock. On August 7, 2013, we completed a public offering of our Series B Preferred Stock, on January 21, 2014, we completed a public offering of our Series C Preferred Stock and on May 13, 2015, we completed a public offering of our Series D Preferred Stock. On July 6, 2016, we implemented a Dividend Reinvestment Plan that offers holders of our common stock the opportunity to purchase additional shares by having their cash dividends automatically reinvested in our common stock at a discount to current market price. On December 5, 2016, we completed a follow-on public offering of our common stock.

Under the Framework Deed, entered into in May 2013 and amended and restated in May 2015, we have agreed with York to invest in newbuild and secondhand container vessels through jointly held companies, thereby increasing our ability to expand our operations while diversifying our risk. The joint venture established by the Framework Deed is expected to be each party’s exclusive joint venture for the acquisition of vessels in the containership industry during the commitment period ending May 18, 2020, unless terminated earlier in certain circumstances (although we may acquire vessels outside the joint venture where York passes on a vessel acquisition opportunity). If York decides to participate in a new vessel acquisition, we will hold a 25% to 75% equity interest in such vessel.

As of May 22, 2017, the joint venture had executed transactions with capital expenditure commitments of approximately $1.2 billion. As of May 22, 2017, the remaining installments for the three newbuilds ordered under the Framework Deed with York were $113.8 million, out of which debt and lease financing had been committed for $109.4 million. The Company’s portion relating to the remaining commitments was $2.1 million. As part of the Framework Deed, we hold a minority stake in the existing Joint Venture vessels and expect to hold a stake of 25% to 75% in future Joint Venture vessels. For more information on the Company’s capital expenditures and divestitures see Note 6 to our unaudited consolidated financial statements included in our Form 6-K furnished to the SEC on May 10, 2017, and incorporated by reference into this prospectus.

Our Fleet and Newbuilds

The tables below provide additional information, as of May 22, 2017, about our fleet of containerships, including our newbuilds on order, the vessels acquired pursuant to the Framework Deed and those vessels subject to sale and leaseback agreements. Each vessel is a cellular containership, meaning it is a dedicated container vessel.

Charter terms and expiration dates are based on the earliest date charters could expire. Amounts set out for current daily charter rate are the amounts contained in the charter contracts.

⁽²⁾

Based on latest shipyard production schedule, subject to change.

⁽³⁾

Assumes exercise of owner’s unilateral options to extend the charter of these vessels for two one-year periods at the same charter rate. The charterer also has corresponding options to unilaterally extend the charter for the same periods at the same charter rate.

⁽⁴⁾

This vessel is expected to be delivered to the charterer in June 2017.

⁽⁵⁾

Pursuant to an agreement with the charterers, it was agreed the vessels will be redelivered to the Company earlier than the original redelivery date, which was in December 2017 for Maersk Kure and Maersk Kawasaki and February 2018 for Maersk Kokura. The expiration dates shown above for Maersk Kure and Maersk Kokura are the new redelivery dates. Charterers have the option to employ each of these two vessels for an additional period of up to six months, commencing on the new redelivery date, paying a daily hire rate of $10,500 per day per vessel for the first two months and $14,000 per day per vessel thereafter. Charterers had a similar extension option for Maersk Kawasaki, which they exercised.

⁽⁶⁾

The amounts in the table reflect the current charter terms, giving effect to our agreement with Zim under its 2014 restructuring plan. Based on this agreement, we have been granted charter extensions and have been issued equity securities representing 1.2% of Zim’s equity and approximately $8.2 million in interest bearing notes maturing in 2023. In July 2016 the Company exercised its option to extend the charters of Zim New York and Zim Shanghai for an additional one-year period at market rate plus $1,100 per day per vessel while the notes remain outstanding. The rate for this second optional year has been determined at $7,736 per day.

⁽⁷⁾

This charter rate will start on December 7, 2017. From delivery of the vessel until December 7, 2017, the charter rate will be $6,000 per day.

⁽⁸⁾

This charter rate will start on November 24, 2017. From delivery of the vessel until November 24, 2017, the charter rate will be $6,000 per day.

⁽⁹⁾

Two of the three vessels have been chartered for a period of 7 to 13 months and the third vessel for a period of 3 to 13 months at charterers’ option.

⁽¹⁰⁾

As from December 1, 2012 until redelivery, the charter rate is to be a minimum of $13,500 per day plus 50% of the difference between the market rate and the charter rate of $13,500. The market rate is to be determined annually based on the Hamburg ConTex type 3500 TEU index published on October 1 of each year until redelivery.

⁽ⁱ⁾

Denotes vessels acquired pursuant to the Framework Deed with York. The Company holds an equity interest ranging between 25% and 49% in each of the vessel-owning entities.

⁽ⁱⁱ⁾

Denotes vessels subject to a sale and leaseback transaction

^(*)

Denotes current daily charter rates that are treated as confidential.

^(**)

Denotes newbuild vessels chartered for periods of up to 12 months at an average rate of approximately $18,000 per day.

^(***)

Denotes vessels acquired in May 2017. The acquisitions were initially funded with equity. The Company is in discussions to finance the vessels’ acquisition cost with debt.

Our Competitive Strengths

We believe that we possess a number of competitive strengths that will allow us to capitalize on growth opportunities in the containership sector, including:

Track Record of Navigating Through Strong and Weak Containership Markets.

Consistent with our strategy of actively managing the size of our fleet through timely acquisitions and dispositions, we grew our fleet from 21 containerships with an aggregate capacity of 43,735 TEU in 2000 to a peak of 53 containerships of 227,778 TEU in 2008, followed by a proactive decrease in response to market conditions in 2009 and the first half of 2010 to a fleet of 42 containerships with a total capacity of 213,348 TEU as of June 30, 2010. Since the time of our initial public offering in November 2010, we have paid or committed to pay approximately $1.8 billion in vessel acquisitions and newbuilds, including investments under the Framework Deed. As a result, through the date of this prospectus supplement, we have grown our fleet to 72 containerships with a total capacity of approximately 473,000 TEU, including three newbuilds on order. Eighteen of our containerships, including three newbuilds, have been acquired pursuant to the Framework Deed by vessel-owning Joint Venture entities in which we hold a minority equity interest. We believe that the financial flexibility, together with our experience, reputation, quality of services and long-standing relationships with container shipping industry participants and major financial institutions, position us to continue to renew and expand our fleet, including through our joint venture with York, with further acquisitions of newbuild and high-quality secondhand vessels at attractive prices in today’s low market environment.

Base of Contracted Cash Flows Through Fixed-Duration Charter Coverage and Staggered Charter Expiration Dates.

While the containership market is currently weak, we believe that the fixed-duration and fixed-rate nature of most of our charters, arranged at different points in the shipping cycle, will continue to provide us with a stable base of contracted future revenue. As of May 22, 2017, the average (weighted by TEU capacity) remaining time-charter duration for our fleet of 72 containerships was approximately 3.1 years, based on the remaining fixed terms and assuming the exercise of any owner’s extension options and the non-exercise of any charterer’s extension options under our containerships’ charters. The staggered maturities of the charters for vessels that expire in the next few years mean that we may conduct our re-chartering activity in varying rate environments and may have the opportunity to tailor our charter terms accordingly. As of March 31, 2017, fixed-term charters represented an aggregate of $1.5 billion of contracted revenue, assuming the exercise of any owner’s extension options and the non-exercise of any charterer’s extension options under our containerships’ charters and 365 revenue days per annum per containership (which amount includes our ownership percentage of contracted revenue for the existing Joint Venture vessels). Ten of these charters include an option exercisable by either party to extend the term: five vessels for two one-year periods at the same charter rate, which represents an additional $152.4 million of potential contracted revenue, and five Joint Venture vessels for a three-year period and a subsequent two-year period at the same charter rate, which represents an additional $170.5 million of potential contracted revenue that is attributable to our participation in the relevant vessel-owning entities.

Large, Diversified High-Quality Fleet.

Our fleet of 72 containerships, which includes three newbuilds on order and the 15 vessels in the water acquired pursuant to the Framework Deed with York, consists of containerships of various sizes and has been assembled to meet our customers’ needs and is able to operate on East-West, North-South and Intra-regional trade routes, giving us increased flexibility in re-chartering our containerships. We believe our containerships are built to high standards by reputable shipyards and have been carefully maintained by our managers. We also believe that the reliability of our fleet has been a critical factor in retaining our active and long-standing relationships with the leading liner

S-5

companies. We believe that owning a large, high-quality and diverse fleet provides us with a competitive advantage in securing future employment for our containerships.

Experienced Management Team.

Our company and founders have a long history of operating and investing in the container shipping industry beginning in 1984. Our managers’ senior management teams have a combined average of approximately 40 years of experience in the shipping industry. We believe that we are able to secure attractive fixed duration charters with leading liner companies because of, among other things, our operating track record and our high level of service and support.

Long-Standing Relationships with Leading Charterers.

Though our business is affected by changes in global and regional economic activity and by developments in the containership industry, we believe that by chartering our containerships to leading liner companies, including those we perceive to be most financially and operationally sound, we reduce our potential charter counterparty risk. We currently charter containerships to A.P. Moller-Maersk A/S, Mediterranean Shipping Company, S.A., members of the Evergreen Group, Hapag Lloyd Aktiengesellschaft, Zim Integrated Shipping Services, Sea Consortium Pte Ltd., CMA CGM, members of the Hamburg Süd Group, Pacific International Lines (Pte) Ltd., TS Lines, APL and Cosco Container Lines Co., Ltd.

Access to Capital to Meet Existing Capital Requirements for our Newbuilds and Potential Growth Plans.

Since the time of our initial public offering in November 2010, we have arranged debt financing of approximately $2.3 billion to fund our newbuilding program and vessel acquisitions, including the investments under the Framework Deed with York. As of May 22, 2017, the Joint Venture entities had committed financing for all three newbuild contracts. In addition, as of March 31, 2017, we had $184 million of cash liquidity, consisting of cash, cash equivalents and restricted cash and three unencumbered vessels, all three of which are Joint Venture vessels. We believe that our available liquidity and our access to diversified sources of capital, including debt, equity and our joint venture with York will help us to weather adverse market conditions, meet our existing capital requirements and make additional selective vessel acquisitions as they become available.

Our Business Strategies

Our primary objectives are to profitably grow our business, increase earnings and distributable cash flow per share and maximize value to our stockholders by pursuing the following strategies:

Invest in Vessels at an Attractive Point in the Container Shipping Cycle.

Given our broad and established customer relationships and financial flexibility, we believe we are well-positioned to take advantage of opportunities that may materialize to acquire newbuild and secondhand vessels at attractively low prices. As an established owner of containerships with significant experience and relationships in the containership sector, we believe we will have ready access to vessel acquisition opportunities from shipyards, our liner company customers, other shipowners, financial institutions and shipbrokers; chartering opportunities with leading liner companies; and available financing alternatives that will facilitate the further renewal and expansion of our fleet.

We expect to continue expanding our fleet at the appropriate point in the cycle by acquiring additional containerships at favorable prices through our joint venture with York or on our own using our available resources, which include cash, the net proceeds of this offering and, as necessary and available, borrowings under new credit facilities. To this end, we continually evaluate potential transactions and enter into relevant negotiations for the acquisition of newbuilds and secondhand

S-6

vessels. However, there can be no assurance that we will complete any vessel acquisitions and we may choose to instead reduce our fleet with regard to the perceived market direction.

Actively Manage Portfolio of Charters Through the Shipping Cycle.

We believe that a focus on high-quality charterers and a carefully managed charter expiry profile are critical to our business strategy. Our largest customers for the three months ended March 31, 2017, were A.P. Moller-Maersk, MSC, Evergreen and COSCO, which we perceive to be among the more creditworthy liner companies. We intend to continue chartering our containerships to high-quality charterers and further expand the number of leading liner companies chartering our vessels in order to diversify further our portfolio of time charters from customer, geographic and maturity perspectives. We expect that our strategy will also allow us to re-charter our containerships during various points in the charter market cycle. While we believe that diversifying our customer base is important in order to reduce our revenue concentration and moderate our exposure to any one customer, we will also continue to focus our chartering on high quality, financially strong counterparties. However, there can be no assurance that we may be able to obtain new charters or that our counterparties will continue to honor their contractual obligations.

Continue to Manage Our Balance Sheet and Access to Capital.

We believe that management of our balance sheet, including management of cash and capital commitments, will continue to give us financial flexibility. We believe that we have taken advantage of opportunities at attractive points of the container shipping cycle and that we are well-positioned to continue to do so. As of March 31, 2017, we had $184 million of cash liquidity, consisting of cash, cash equivalents and restricted cash and three unencumbered vessels, all three of which are Joint Venture vessels. As of May 22, 2017, we had outstanding commitments relating to our remaining three contracted newbuilds, which have been ordered under the Framework Deed with York, aggregating approximately $113.8 million payable in installments until the vessels are delivered, out of which $109.4 million will be funded through committed financing. As of May 22, 2017, our remaining equity commitments in the relevant jointly-owned entities amount to $2.1 million.

Provide High-Quality Customer Service.

We seek to provide high-quality customer service that allows our customers to implement integrated logistics solutions in the marketplace. Our managers’ ship management approach is to tailor their services by vessel type and age, which we believe has helped to differentiate us with our charterers and extend our charters and the useful lives of our containerships. We believe that having both affiliated and third-party management companies allows us to have a deep pool of operational management in multiple locations with market-specific experience and relationships, as well as the geographic flexibility needed to manage and crew our large and diverse fleet so as to provide a high level of service, while remaining cost-effective. We also believe that our focus on customer service and reliability enhances our relationships with our charterers. In the past decade, we have had successful chartering relationships with the majority of the top 20 liner companies by TEU capacity.

Dividend Policy

Commencing with a dividend of $0.25 per share for the fourth quarter ended December 31, 2010, we have paid a cash dividend to our stockholders for 26 consecutive quarters since our initial public offering in November 2010. In October 2016, our Board of Directors approved management’s recommendation to declare a $0.10 cash dividend per each common share, and we declared a $0.10 cash dividend per each common share in each of January 2017 and April 2017. We intend to continue to pay our stockholders quarterly dividends of $0.10 per share, or $0.40 per share per year. However, there can be no assurance that we will pay regular quarterly dividends in the future.

On July 6, 2016, we implemented a dividend reinvestment plan (the “Plan”). The Plan offers holders of our common stock the opportunity to purchase additional shares by having their cash

S-7

dividends automatically reinvested in our common stock. Participation in the Plan is optional, and shareholders who decide not to participate in the Plan will continue to receive cash dividends, as declared and paid in the usual manner. As committed shareholders, members of the founding family, currently controlling an interest of approximately 60% of the Company’s common stock prior to this offering, have each reinvested in full their cash dividends since the inception of the Plan.

Our board of directors may review and amend our dividend policy from time to time in light of our plans for future growth and other factors. We cannot assure you that we will be able to pay regular quarterly dividends in the amounts stated above or elsewhere in this prospectus, and our ability to pay dividends will be subject to the restrictions in our credit facilities and the provisions of the laws of the Republic of the Marshall Islands (the “Marshall Islands”) as well as the other limitations set forth in the sections of this prospectus entitled “Dividend Policy” and “Risk Factors.”

For purposes of calculating the ratios of earnings to fixed charges and to fixed charges and preferred stock dividends:

•

“earnings” consist of pre-tax income from continuing operations before adjustment for equity investees (which include non-cash unrealized gains and losses on derivative financial instruments) plus fixed charges, net of capitalized interest and capitalized amortization of deferred financing fees, amortization of capitalized interest, distributed income of equity investees, less loss from equity investees with guaranteed debt;

•

“fixed charges” represent interest incurred (whether expensed or capitalized), interest expense of loss-making, equity investees with guaranteed debt and amortization of deferred financing costs (whether expensed or capitalized) and accretion of discount. Costamare is guarantor for the debt (including sale and leaseback transactions) of certain equity investees; and

•

“preferred stock dividends” refers to the amount of pre-tax earnings that is accrued for dividends on outstanding preferred stock. Beginning on August 7, 2013, we had 2,000,000 shares of Series B Preferred Stock outstanding, beginning on January 21, 2014, we had 4,000,000 shares of Series C Preferred Stock outstanding and beginning on May 13, 2015, we had 4,000,000 shares of Series D Preferred Stock outstanding.

DIVIDEND POLICY

On July 6, 2016, we implemented a dividend reinvestment plan. The Plan offers holders of our common stock the opportunity to purchase additional shares by having their cash dividends automatically reinvested in our common stock. Participation in the Plan is optional, and shareholders who decide not to participate in the Plan will continue to receive cash dividends, as declared and paid in the usual manner. As committed shareholders, members of the founding family, controlling an interest of approximately 60% of the Company common stock prior to this offering, have each reinvested in full their cash dividends since the inception of the Plan.

We currently intend to pay dividends in amounts that will allow us to retain a portion of our cash flows to fund vessel, fleet or company acquisitions that we expect to be accretive to earnings and cash flows and for debt repayment and dry-docking costs, as determined by management and our board of directors. Our board of directors may review and amend our dividend policy from time to time in light of our plans for future growth and other factors, and our ability to pay dividends will be subject to the restrictions in our credit facilities and the provisions of the Marshall Islands law. The timing and amount of dividend payments will be dependent upon our earnings, financial condition, cash requirements and availability, fleet renewal and expansion and other factors. We cannot assure you that we will be able to pay regular quarterly dividends in the amounts stated above or elsewhere in this prospectus, and dividends may be discontinued at any time at the discretion of our board of directors. Our ability to pay dividends may be limited by the amount of cash we can generate from operations following the payment of fees and expenses and the establishment of any reserves, as well as additional factors unrelated to our profitability. We are a holding company, and we depend on the ability of our subsidiaries to distribute funds to us in order to satisfy our financial obligations and to make dividend payments. See “Item 3. Key Information—D. Risk Factors—Risks Inherent in Our Business” beginning on page 3 of our Annual Report on Form 20-F and incorporated by reference into this prospectus for a discussion of the risks related to our ability to pay dividends.

Set out below is a table showing the dividends and distributions paid in 2012, 2013, 2014, 2015, 2016 and the first three months of 2017.

UNDERWRITING

Under the terms and subject to the conditions in an underwriting agreement dated the date of this prospectus supplement, the underwriters named below have indicated their intention to purchase, and we have agreed to sell to the underwriters, the number of shares of our common stock indicated below:


Name	Number of Shares
Morgan Stanley & Co. LLC		6,986,250
Wells Fargo Securities, LLC		2,598,750
J.P. Morgan Securities LLC		1,350,000
Citigroup Global Markets Inc.		1,350,000
Stifel, Nicolaus & Company, Incorporated		1,215,000

Total		13,500,000

The underwriters are offering the shares of common stock subject to their acceptance of the shares from us. The underwriting agreement provides that the obligations of the underwriters to pay for and accept delivery of the shares of our common stock offered by this prospectus are subject to the approval of certain legal matters by the underwriters’ counsel and to certain other conditions. The underwriters are obligated to take and pay for all of the shares of our common stock offered by this prospectus if any such shares are taken. However, the underwriters are not required to take or pay for the shares covered by the underwriters’ option to purchase additional shares described below.

The underwriters initially propose to offer part of the shares of our common stock directly to the public at the offering price listed on the cover page of this prospectus and part to certain dealers. After the initial offering of the shares of our common stock, the offering price and other selling terms may from time to time be varied by the underwriters.

We have granted to the underwriters an option, exercisable for 30 days from the date of this prospectus supplement, to purchase up to 2,025,000 additional shares of our common stock at the public offering price listed on the cover page of this prospectus, less underwriting discounts. Any shares of our common stock issued and sold under the option will be issued and sold on the same terms and conditions as the other shares of our common stock that are the subject of this offering.

The following table shows the per share and total public offering price, underwriting discounts and proceeds before expenses to us. These amounts are shown assuming both no exercise and full exercise of the underwriters’ option to purchase up to an additional 2,025,000 shares of our common stock.


	Per Share			Total
	Per Share			No Exercise			Full Exercise
Public offering price		$	7.10		$	95,850,000		$	110,227,500
Underwriting discounts paid by us⁽¹⁾		$	0.3195		$	3,863,250		$	4,510,238

Proceeds, before expenses, to us		$	6.7805		$	91,986,750		$	105,717,262

(1)

The underwriters will not receive an underwriting discount or commission on the sale of approximately $10,000,000 of shares of our common stock to members of the Konstantakopoulos family.

The estimated offering expenses payable by us, exclusive of the underwriting discounts, are approximately $330,000. We have agreed to reimburse the underwriters for certain legal expenses relating solely to state “Blue Sky” qualifications and FINRA filings in connection with the offering in an amount not to exceed $2,000 and $8,000, respectively, which reimbursement is deemed underwriting compensation by FINRA.

Our common stock is listed on the New York Stock Exchange under the trading symbol “CMRE.”

We, our officers and directors and members of the Konstantakopoulos family have agreed not to sell or transfer any shares of our common stock or securities convertible into, exchangeable for,

S-21

exercisable for or repayable with common stock, for 90 days after the date of this prospectus supplement without first obtaining the written consent of Morgan Stanley & Co. LLC. Specifically, we, our officers, our directors and members of the Konstantakopoulos family have agreed, with certain limited exceptions, not to directly or indirectly:

•

offer, pledge, sell or contract to sell any shares of common stock;

•

sell any option or contract to purchase any shares of common stock;

•

purchase any option or contract to sell any shares of common stock;

•

grant any option, right or warrant for the sale of any shares of common stock;

•

lend or otherwise dispose of or transfer any shares of common stock;

•

request or demand that we file a registration statement related to the common stock; or

•

enter into any swap or other agreement that transfers, in whole or in part, the economic consequences of ownership of any shares of common stock whether any such swap or transaction is to be settled by delivery of shares or other securities, in cash or otherwise.

These lock-up provisions apply to shares of our common stock and to securities convertible into or exchangeable or exercisable for or repayable with our common stock. These provisions also apply to shares of our common stock owned now or acquired later by such persons or for which such persons later acquire the power of disposition. The restrictions described above do not apply to:

•

the sale of shares to the underwriters;

•

transactions by a stockholder relating to shares of common stock or other securities acquired in open market transactions after the completion of this offering; provided that no filing under Section 16(a) of the Exchange Act is required or voluntarily made;

•

distributions by the Company pursuant to the Plan;

•

the issuance of shares of common stock by the Company pursuant to an existing services agreement;

•

the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act, for the transfer of shares of common stock, provided that such plan does not provide for the transfer of common stock during the 90-day restricted period;

•

transfers by a stockholder of shares of common stock or any security convertible into common stock as a bona fide gift;

•

distributions by a stockholder of shares of common stock or any security convertible into common stock to limited partners or stockholders of such stockholder; or

•

transfers by a stockholder of shares of common stock or any security convertible into common stock to any immediate family member of such stockholder or any trust or other entity for the direct or indirect benefit of such stockholder or the immediate family of such stockholder;

provided, with respect to the transfers described in the last three bullet points above, that any donee, distributee, transferee or beneficiary agrees to be subject to the restrictions described in this paragraph and no filing under Section 16(a) of the Exchange Act is required or voluntarily made.

In order to facilitate the offering of the shares of our common stock, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of our common stock. Specifically, the underwriters may sell more shares than they are obligated to purchase under the underwriting agreement, creating a short position. A short sale is covered if the short position is no greater than the number of shares available for purchase by the underwriters under their option to purchase additional shares. The underwriters can close out a covered short sale by exercising their option to purchase additional shares or purchasing shares in the open market. In determining the source of shares to close out a covered short sale, the underwriters will consider, among other things, the open market price of shares compared to the price available under their option to purchase additional shares. The underwriters may also sell shares in excess of their option to purchase additional shares, creating a naked short position. The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely

S-22

to be created if the underwriters are concerned that there may be downward pressure on the price of our common stock in the open market after pricing that could adversely affect investors who purchase in this offering. As an additional means of facilitating this offering, the underwriters may bid for, and purchase, shares of our common stock in the open market to stabilize the price of our common stock. These activities may raise or maintain the market price of our common stock above independent market levels or prevent or retard a decline in the market price of our common stock. The underwriters are not required to engage in these activities and may end any of these activities at any time.

We and the underwriters have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act.

A prospectus in electronic format may be made available on websites maintained by the underwriters, or selling group members, if any, participating in this offering. The underwriters may agree to allocate a number of shares of our common stock for sale to their online brokerage account holders. Internet distributions will be allocated by the underwriters for Internet distributions on the same basis as other allocations.

The underwriters and their affiliates are full-service financial institutions and have, from time to time, performed, and may in the future perform, various financial advisory, commercial banking and investment banking services for us, for which they received or will receive customary fees and expenses. Charlotte Stratos, who is a member of our board of directors, is a consulting Senior Advisor to the Investment Banking Division of Morgan Stanley & Co. LLC, an underwriter of this offering.

Unless we otherwise specify, when used in this prospectus the terms “Costamare”, the “Company”, “we”, “our”, “us” or similar terms refer to Costamare Inc. and its subsidiaries and/or any one of them. We use the term “twenty foot equivalent unit” or “TEU”, the international standard measure of containers, in describing the capacity of our containerships.

THE COMPANY

We are an international owner of containerships, chartering our vessels to many of the world’s largest liner companies. As of October 24, 2016, we had a fleet of 71 containerships with a total capacity of approximately 464,000 TEU, including six newbuilds on order, making us one of the largest public containership companies in the world based on total TEU capacity. At that date, our fleet consisted of (i) 65 vessels in the water, aggregating approximately 412,480 TEU and (ii) six newbuild vessels aggregating approximately 51,640 TEU that are scheduled to be delivered to us through the second quarter of 2018, based on the current shipyard schedule. Eighteen of our containerships, including six newbuilds on order, have been acquired pursuant to the Framework Deed with York Capital Management by vessel-owning joint venture entities in which we hold a minority equity interest.

Costamare Inc. was incorporated in the Republic of The Marshall Islands on April 21, 2008 under the Marshall Islands Business Corporations Act, for the purpose of completing a reorganization of 53 ship-owning companies then owned by our chief executive officer and other members of the Konstantakopoulos family under a single corporate holding company. We are controlled by members of the Konstantakopoulos family, which has a long history of operating and investing in the international shipping industry, including a long history of vessel ownership. We were founded in 1974 and initially owned and operated drybulk carrier vessels. In 1984 we became the first Greek-owned company to enter the containership market and, since 1992, we have focused exclusively on containerships. After assuming management of our company in 1998, Konstantinos Konstantakopoulos has concentrated on building a large, modern and reliable containership fleet run and supported by highly skilled, experienced and loyal personnel. He founded the management company Shanghai Costamare in 2005, and the manning agency C-Man Maritime Inc. in 2006. Under Konstantinos Konstantakopoulos’s leadership, we have continued to foster a company culture focusing on excellent customer service, industry leadership and innovation.

In November 2010, we completed an initial public offering of shares of our common stock and have since offered additional shares of common stock through two follow-on offerings. In August 2013, we completed an offering of shares of 7.625% Series B Cumulative Redeemable Perpetual Preferred Stock (“Series B Preferred Stock”). In January 2014, we completed an offering of shares of 8.50% Series C Cumulative Redeemable Perpetual Preferred Stock (“Series C Preferred Stock”). In May 2015, we completed an offering of shares of 8.75% Series D Cumulative Redeemable Perpetual Preferred Stock (“Series D Preferred Stock”). Our common stock, Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock are listed on the New York Stock Exchange. If any securities are to be listed or quoted on any other securities exchange or quotation system, the applicable prospectus supplement will so state.

We maintain our principal executive offices at 7 Rue du Gabian, MC 98000 Monaco. Our telephone number at such address is +377 93 25 09 40. We maintain a website at www.costamare.com. The information contained on or linked to or from our website is not incorporated herein by reference. Our registered address in the Marshall Islands is Trust Company Complex, Ajeltake Road, Ajeltake Island, Majuro, Marshall Islands MH96960. The name of our registered agent at such address is The Trust Company of the Marshall Islands, Inc.

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

RISK FACTORS

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

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

SERVICE OF PROCESS AND ENFORCEMENT OF LIABILITIES

We are a Marshall Islands corporation and our principal executive offices are located outside of the United States in Monaco. All of our directors and officers and some of the experts in this prospectus reside outside the United States. In addition, all or a substantial portion of our assets and the assets of our directors, officers and experts are located outside of the United States. As a result, you may have difficulty serving legal process within the United States upon us or any of these persons. You may also have difficulty enforcing, both in and outside of the United States, judgments you may obtain in U.S. courts against us or these persons in any action, including actions based upon the civil liability provisions of U.S. Federal or state securities laws.

Furthermore, there is uncertainty as to whether the courts of the Marshall Islands, Monaco or other countries where our directors may reside would enter judgments in original actions brought in those courts predicated on U.S. Federal or state securities laws.

ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we filed with the SEC using a shelf registration process. Under this shelf registration process, we may, from time to time, sell up to an aggregate public offering price of $300,000,000 of any combination of the securities described in this prospectus in one or more offerings. This prospectus provides you with a general description of the securities we may offer. Each time we sell securities, we will provide you with this prospectus, as well as a prospectus supplement that will contain specific information about the terms of that offering. That prospectus supplement may include additional risk factors or other special considerations applicable to those particular securities. Any prospectus supplement may also add, update or change information contained in this prospectus. If there is any inconsistency between the information contained in this prospectus and any prospectus supplement, you should rely on the information contained in that particular prospectus supplement. You should read both this prospectus and any prospectus supplement together with additional information described under the heading “Where You Can Find Additional Information”.

WHERE YOU CAN FIND ADDITIONAL INFORMATION

We have filed with the SEC a registration statement on Form F-3 under the Securities Act of 1933, as amended (the “Securities Act”), with respect to the offer and sale of securities pursuant to this prospectus. This prospectus, filed as a part of the registration statement, does not contain all of the information set forth in the registration statement. The registration statement includes and incorporates by reference additional information and exhibits. Statements made in this prospectus concerning the contents of any contract, agreement or other document filed as an exhibit to the registration statement are summaries of all of the material terms of such contracts, agreements or documents, but do not repeat all of their terms. Reference is made to each such exhibit for a more complete description of the matters involved and such statements shall be deemed qualified in their entirety by such reference. The registration statement and the exhibits and schedules thereto filed

with the SEC may be inspected, without charge, and copies may be obtained at prescribed rates, at the public reference facility maintained by the SEC at its principal office at 100 F Street, N.E., Washington, D.C. 20549. You may obtain information on the operation of the public reference facility by calling 1-800-SEC-0330. The SEC also maintains a website at http://www.sec.gov that contains reports, proxy and information statements and other information regarding registrants that file electronically with the SEC. For further information pertaining to the securities offered by this prospectus and Costamare Inc., reference is made to the registration statement.

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

DESCRIPTION OF PREFERRED STOCK

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

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

•

the designation of the series;

•

the number of shares in the series, which our board of directors may, except where otherwise provided in the preferred shares designation, increase or decrease, but not below the number of shares then outstanding;

•

whether dividends, if any, will be cumulative or non-cumulative and the dividend rate of the series;

•

the dates at which dividends, if any, will be payable;

•

the redemption rights and price or prices, if any, for shares of the series;

•

the terms and amounts of any sinking fund provided for the purchase or redemption of shares of the series;

•

the amounts payable on shares of the series in the event of any voluntary or involuntary liquidation, dissolution or winding-up of the affairs of our company;

•

whether the shares of the series will be convertible into shares of any other class or series, or any other security, of our company or any other corporation, and, if so, the specification of the other class or series or other security, the conversion price or prices or rate or rates, any rate adjustments, the date or dates as of which the shares will be convertible and all other terms and conditions upon which the conversion may be made;

•

restrictions on the issuance of shares of the same series or of any other class or series; and

•

the voting rights, if any, of the holders of the series.

On August 7, 2013, we issued 2,000,000 shares of our Series B Preferred Stock. The terms of the statement of designation allow us to issue additional shares of the Series B Preferred Stock.

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

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

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

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

General

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

Payments

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

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

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

Registration and Transfer of Debt Securities

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

Events of Default

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

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

•

default is made for more than 30 days in the payment of interest, premium or principal in respect of the securities;

•

we fail to perform or observe any of our other obligations under the securities and this failure has continued for the period of 60 days next following the service on us of notice requiring the same to be remedied;

•

our bankruptcy, insolvency or reorganization under any applicable bankruptcy, insolvency or insolvency related reorganization law;

•

an order is made or an effective resolution is passed for the winding up or liquidation of us; or

•

any other event of default provided in the supplemental indenture or issuer order, if any, under which that series of debt securities is issued.

Acceleration of Debt Securities Upon an Event of Default

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

•

if an event of default occurs due to the default in payment of principal of, or any premium or interest on, any series of debt securities issued under the indenture, or due to the default in the performance or breach of any other covenant or warranty of us applicable to that series of debt securities but not applicable to all outstanding debt securities issued under the indenture occurs and is continuing, either the trustee or the holders of not less than 25% in aggregate principal amount of the outstanding debt securities of each affected series, voting as one class, by notice in writing to us may declare the principal of and accrued interest on the debt securities of such affected series (but not any other debt securities issued under the indenture) to be due and payable immediately;

•

if an event of default occurs due to specified events of bankruptcy, insolvency or reorganization of us, the principal of all debt securities and interest accrued on the debt securities to be due and payable immediately; and

•

if an event of default due to a default in the performance of any other of the covenants or agreements in the indenture applicable to all outstanding debt securities issued under the indenture occurs and is continuing, either the trustee or the holders of not less than 25% in

aggregate principal amount of all outstanding debt securities issued under the indenture for which any applicable supplemental indenture does not prevent acceleration under the relevant circumstances, voting as one class, by notice in writing to us may declare the principal of all debt securities and interest accrued on the debt securities to be due and payable immediately.

Annulment of Acceleration and Waiver of Defaults

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

Indemnification of Trustee for Actions Taken on Your Behalf

The indenture provides that the trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the holders of debt securities issued under the indenture relating to the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred upon the trustee. In addition, the indenture contains a provision entitling the trustee, subject to the duty of the trustee to act with the required standard of care during a default, to be indemnified to its satisfaction by the holders of debt securities issued under the indenture before proceeding to exercise any right or power at the request of holders. Subject to these provisions and specified other limitations, the holders of a majority in aggregate principal amount of each series of outstanding debt securities of each affected series, voting as one class, may direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee.

Limitation on Actions by You as an Individual Holder

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

•

the holder must have previously given written notice to the trustee of the continuing default;

•

the holders of not less than 25% in aggregate principal amount of the outstanding debt securities of each affected series, treated as one class, must have:

•

requested the trustee to institute that action; and

•

offered the trustee indemnity satisfactory to it;

•

the trustee must have failed to institute that action within 60 days after receipt of the request referred to above; and

•

the holders of a majority in principal amount of the outstanding debt securities of each affected series, voting as one class, must not have given directions to the trustee inconsistent with those of the holders referred to above.

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

Discharge, Defeasance and Covenant Defeasance

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

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

•

paid or caused to be paid the principal of and interest on all of the outstanding debt securities in accordance with their terms;

•

delivered to the trustee for cancellation all of the outstanding debt securities; or

•

irrevocably deposited with the trustee cash or, in the case of a series of debt securities payable only in U.S. dollars, U.S. government obligations in trust for the benefit of the holders of any series of debt securities issued under the indenture that have either become due and payable, or are by their terms due and payable, or are scheduled for redemption, within one year, in an amount certified to be sufficient to pay on each date that they become due and payable, the principal of and interest on, and any mandatory sinking fund payments for, those debt securities. However, the deposit of cash or U.S. government obligations for the benefit of holders of a series of debt securities that are due and payable, or are scheduled for redemption, within one year will discharge obligations under the indenture relating only to that series of debt securities.

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

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

•

we irrevocably deposit with the trustee cash or, in the case of debt securities payable only in U.S. dollars, U.S. government obligations, as trust funds in an amount certified to be sufficient to pay on each date that they become due and payable, the principal of and interest on, and any mandatory sinking fund payments for, all outstanding debt securities of the series being defeased; and

•

we deliver to the trustee an opinion of counsel to the effect that:

•

the holders of the series of debt securities being defeased will not recognize income, gain or loss for United States federal income tax purposes as a result of the defeasance or covenant defeasance;

•

the defeasance or covenant defeasance will not otherwise alter those holders’ United States federal income tax treatment of principal and interest payments on the series of debt securities being defeased; and

•

in the case of a defeasance, this opinion must be based on a ruling of the Internal Revenue Service or a change in United States federal income tax law occurring after the date of this prospectus, since that result would not occur under current tax law.

Modification of the Indenture

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

•

secure any debt securities;

•

evidence the assumption by a successor corporation of our obligations;

•

add covenants for the protection of the holders of debt securities;

•

cure any ambiguity or correct any inconsistency;

•

establish the forms or terms of debt securities of any series; or

•

evidence the acceptance of appointment by a successor trustee.

Modification with Consent of Holders. We and the trustee, with the consent of the holders of not less than a majority in aggregate principal amount of each affected series of outstanding debt securities, voting as one class, may add any provisions to, or change in any manner or eliminate any of the provisions of, the indenture or modify in any manner the rights of the holders of those debt

securities. However, we and the trustee may not make any of the following changes to any outstanding debt security without the consent of each holder that would be affected by the change:

•

extend the final maturity of the security;

•

reduce the principal amount;

•

reduce the rate or extend the time of payment of interest;

•

reduce any amount payable on redemption;

•

change the currency in which the principal, including any amount of original issue discount, premium, or interest on the security is payable;

•

modify or amend the provisions for conversion of any currency into another currency;

•

reduce the amount of any original issue discount security payable upon acceleration or provable in bankruptcy;

•

alter the terms on which holders of the debt securities may convert or exchange debt securities for common stock or other securities, other than in accordance with the antidilution provisions or other similar adjustment provisions included in the terms of the debt securities;

•

impair the right of any holder to institute suit for the enforcement of any payment on any debt security when due; or

•

reduce the percentage of debt securities the consent of whose holders is required for modification of the indenture.

Form of Debt Security

Each debt security will be represented either by a certificate issued in definitive form to a particular investor or by one or more global securities representing the entire issuance of securities. Both certificated securities in definitive form and global securities may be issued either:

•

in registered form, where our obligation runs to the holder of the security named on the face of the security; or

•

in bearer form, where our obligation runs to the bearer of the security.

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

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

Global Securities

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

security will be described in the prospectus supplement relating to those securities. We anticipate that the following provisions will apply to all depositary arrangements:

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

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

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

If the depositary for any of these securities represented by a registered global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Exchange Act, and a successor depositary registered as a clearing agency under the Exchange Act is not appointed by us within 90 days, we will issue securities in definitive form in exchange for the registered global security that had been held by the depositary. In addition, we may, at any time and in our sole discretion, decide not to have any of the securities represented by one or more registered global securities. If we make that decision, we will issue securities in definitive form in

exchange for all of the registered global security or securities representing those securities. Any securities issued in definitive form in exchange for a registered global security will be registered in the name or names that the depositary gives to the relevant trustee or other relevant agent of ours or theirs. It is expected that the depositary’s instructions will be based upon directions received by the depositary from participants with respect to ownership of beneficial interests in the registered global security that had been held by the depositary.

Bearer Global Securities. The securities may also be issued in the form of one or more bearer global securities that will be deposited with a common depositary for the Euroclear System and Clearstream Banking, société anonyme or with a nominee for the depositary identified in the prospectus supplement relating to those securities. The specific terms and procedures, including the specific terms of the depositary arrangement, with respect to any securities to be represented by a bearer global security will be described in the prospectus supplement relating to those securities.

New York Law to Govern

The indenture and the debt securities will be governed by the laws of the State of New York.

DESCRIPTION OF THE UNITS

We may issue units consisting of common stock, preferred stock, warrants, rights and debt securities, or in combination thereof.

Thus, 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.

PLAN OF DISTRIBUTION

We may offer and sell, from time to time, some or all of the securities covered by this prospectus up to an aggregate public offering price of $300,000,000. We have registered the securities covered by this prospectus for offer and sale so that those securities may be freely sold to the public. Registration of the securities covered by this prospectus does not mean, however, that those securities necessarily will be offered or sold.

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

•

on the NYSE or any other national securities exchange or U.S. inter-dealer system of a registered national securities association on which our common stock may be listed or quoted at the time of sale;

•

in the over-the-counter market;

•

in privately negotiated transactions;

•

in an exchange distribution in accordance with the rules of the applicable exchange;

•

as settlement of short sales entered into after the date of the prospectus;

•

through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

•

through broker-dealers, who may act as agents or principals;

•

through sales “at the market” to or through a market-maker;

•

in a block trade, in which a broker-dealer will attempt to sell a block as agent but may position and resell a portion of the block as principal to facilitate the transaction;

•

through one or more underwriters on a firm commitment or best-efforts basis;

•

directly to one or more purchasers;

•

through agents;

•

in options transactions;

•

over the Internet;

•

any other method permitted pursuant to applicable law; or

•

in any combination of the above.

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

•

purchases of the securities by a broker-dealer as principal and resales of the securities by the broker-dealer for its account pursuant to this prospectus;

•

ordinary brokerage transactions; or

•

transactions in which the broker-dealer solicits purchasers.

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

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

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

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

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

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

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