2020 ANNUAL MEETING OF STOCKHOLDERS

TO BE HELD ON THURSDAY, DECEMBER 21, 2020

GENERAL INFORMATION CONCERNING THE ANNUAL MEETING

Why Did You Send Me this Proxy Statement?

We sent you this proxy statement and the enclosed proxy card because our Board of Directors is soliciting your proxy to vote at the 2020 annual meeting of stockholders and any adjournments of the meeting to be held at 11:00 a.m., local time, on Monday, December 21, 2020, at our offices at 7 Avenue de Grande Bretagne, Office 11B2, Monaco. This proxy statement, along with the accompanying Notice of Annual Meeting of Stockholders, summarizes the purposes of the meeting and the information you need to know to vote at the annual meeting.

On November 16, 2020, we began sending this proxy statement, the attached notice of annual meeting and the enclosed proxy card to all stockholders entitled to vote at the meeting. You can find a copy of our 2019 Annual Report on Form 20-F on the Internet through our website at www.navios-acquisition.com or the U.S. Securities and Exchange Commission’s electronic data system called EDGAR at www.sec.gov.

Who Can Vote?

Only stockholders who owned our common stock at the close of business on November 13, 2020 are entitled to vote at the annual meeting. On this record date, there were 17,103,371 shares of our common stock outstanding and entitled to vote. Our common stock is our only class of voting stock. The shares of common stock are listed on the New York Stock Exchange under the symbol “NNA.”

You do not need to attend the annual meeting to vote your shares. Shares represented by valid proxies, received in time for the meeting and not revoked prior to the meeting, will be voted at the meeting. A stockholder may revoke a proxy before the proxy is voted by delivering to our Secretary a signed statement of revocation or a duly executed proxy card bearing a later date. Any stockholder who has executed a proxy card but attends the meeting in person may revoke the proxy and vote at the meeting.

How Many Votes Do I Have?

Each share of our common stock that you own entitles you to one vote.

How Do I Vote?

Whether you plan to attend the annual meeting or not, we urge you to vote by proxy. Voting by proxy will not affect your right to attend the annual meeting. If your shares are registered directly in your name through our stock transfer agent, Continental Stock Transfer & Trust Company, or you have stock certificates, you may vote:

If your shares are held in “street name” (held in the name of a bank, broker or other nominee), you must provide the bank, broker or other nominee with instructions on how to vote your shares and can do so as follows:

“Street name” holders may vote by telephone or Internet if their bank, broker or other nominee makes those methods available, in which case the bank, broker or other nominee will enclose the instructions with the proxy materials. The telephone and Internet voting procedures are designed to authenticate stockholders’ identities, to allow stockholders to vote their shares, and to confirm that their instructions have been recorded properly.

How Does the Board of Directors Recommend That I Vote on the Proposals?

The Board of Directors recommends that you vote as follows:

If any other matter is presented, the proxy card provides that your shares will be voted by the proxy holder listed on the proxy card in accordance with his or her best judgment. At the time this proxy statement was printed, we knew of no matters that needed to be acted on at the annual meeting, other than those discussed in this proxy statement.

May I Revoke My Proxy?

If you give us your proxy, you may revoke it at any time before the annual meeting. You may revoke your proxy in any one of the following ways:

What Constitutes a Quorum for the Meeting?

The presence, in person or by proxy, of the holders of no less than a majority of the outstanding shares of our common stock is necessary to constitute a quorum at the meeting. Votes of stockholders of record who are present at the meeting in person or by proxy, withheld votes, abstentions, and broker non-votes are counted for purposes of determining whether a quorum exists.

PROPOSAL ONE

ELECTION OF CLASS C DIRECTORS

Our Board of Directors consists of seven directors, who are divided into three classes. As provided in our Articles of Incorporation, each director is elected to serve for a three-year term and until such director’s successor is duly elected and qualified, except in the event of such director’s death, resignation, removal or earlier termination of such director’s term of office. The terms of the two Class C directors will expire at the 2020 annual meeting. Accordingly, the Board of Directors has nominated Angeliki Frangou and Anna Kalathakis, each of whom is currently a Class C director, for election as directors, whose terms would expire at our 2023 annual meeting of stockholders.

Unless the proxy is marked to indicate that such authorization is expressly withheld, the persons named in the enclosed proxy intend to vote the shares authorized thereby FOR the election of the following two nominees. It is expected that each of these nominees will be able to serve, but if before the election it develops that one or more of the nominees is unavailable, the persons named in the accompanying proxy will vote for the election of such substitute nominee or nominees as the current Board of Directors may recommend.

Angeliki Frangou has been our Chairman and Chief Executive Officer since our inception. Ms. Frangou has also been Chairman and CEO of Navios Maritime Holdings Inc. (NYSE: NM) — our sponsor — since August 2005. In addition, Ms. Frangou has been the Chairman and Chief Executive Officer of Navios Maritime Partners L.P. (NYSE: NMM), an affiliated limited partnership, since August 2007, and the Chairman and Chief Executive Officer of Navios Maritime Containers L.P. (Nasdaq: NMCI), an affiliated limited partnership, since April 2017. Ms. Frangou has been the Chairman of the Board of Directors of Navios South American Logistics Inc. since its inception in December 2007. Ms. Frangou is the Chairman of IRF European Finance Investments Ltd., listed on the SFM of the London Stock Exchange, and is also a Member of the Board of the United Kingdom Mutual Steam Ship Assurance Association (Bermuda) Limited. Since 2015, she has also been a Board Member of the Union of Greek Shipowners, as well as on the Board of Trustees of Fairleigh Dickinson University. Since 2013, Ms. Frangou has been a Member of the Board of Visitors of the Columbia University School of Engineering and Applied Science. Ms. Frangou also acts as Vice Chairman of the China Classification Society Mediterranean Committee, and is a member of the International General Committee and of the Hellenic and Black Sea Committee of Bureau Veritas, and is also a member of the Greek Committee of Nippon Kaiji Kyokai. Ms. Frangou received a bachelor’s degree in Mechanical Engineering, summa cum laude, from Fairleigh Dickinson University and a master’s degree in Mechanical Engineering from Columbia University.

Anna Kalathakis has been a member of our Board of Directors and Senior Vice President — Legal Risk Management since May 2010. Ms. Kalathakis has been Chief Legal Risk Officer since November 2012 and Senior Vice President — Legal Risk Management of Navios Maritime Holdings Inc. from December 2005 until October 2012. Before joining Navios Maritime Holdings Inc., Ms. Kalathakis was the General Manager of the Greek office of A Bilbrough & Co. Ltd. (Managers of the London Steam-Ship Owners’ Mutual Insurance Association Limited, the “London P&I Club”) and an Associate Director of the London P&I Club where she gained experience in the handling of liability and contractual disputes in both the dry and tanker shipping sectors (including collisions, oil pollution incidents, groundings, etc.). She previously worked for a U.S. maritime law firm in New Orleans, having qualified as a lawyer in Louisiana in 1995, and also served in a similar capacity for

a London maritime law firm. She qualified as a solicitor in England and Wales in 1999 and was admitted to the Piraeus Bar in Greece in 2003. She received a bachelor’s degree in International Relations from Georgetown University; she holds a Master of Business Administration degree from European University in Brussels; and a Juris Doctor degree from Tulane Law School.

Required Vote. Stockholders may cast their vote “for” or “withhold” authority to vote for Proposal One. The directors will be elected by a plurality of the votes cast by holders of the shares of our common stock, meaning that the two nominees for director receiving the highest number of shares voted “for” their election will be elected. “Withhold” votes and broker non-votes are not considered votes cast and will have no effect on the election of directors.

Effect of withheld votes and broker non-votes. Withheld votes will not affect the vote on Proposal One. Brokerage firms do not have authority to vote customers’ unvoted shares held by the firms in street name for the election of directors. As a result, any shares not voted by a beneficial owner will be treated as a broker non-vote. Such broker non-votes will have no effect on the results of this vote.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THE ELECTION OF ANGELIKI FRANGOU AND ANNA KALATHAKIS AS CLASS C DIRECTORS, AND PROXIES RECEIVED BY THE BOARD OF DIRECTORS WILL BE VOTED IN FAVOR THEREOF UNLESS A STOCKHOLDER HAS INDICATED OTHERWISE ON THE PROXY.

PROPOSAL TWO

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors is submitting for approval the appointment of Ernst & Young (Hellas) Certified Auditors-Accountants S.A. (“Ernst & Young”) as our independent registered public accounting firm for the fiscal year ending December 31, 2020. The Board of Directors proposes that the stockholders ratify this appointment. Ernst & Young audited our financial statements for the fiscal year ending December 31, 2019.

Ernst & Young has advised us that it does not have any direct or indirect financial interest in us, nor has it had any such interest in connection with us during the past three years other than in its capacity as our independent registered public accounting firm.

All services rendered by Ernst & Young are subject to review by the Audit Committee of our Board of Directors.

We are not required to obtain the approval of our stockholders to select our independent registered public accounting firm. In the event the stockholders do not ratify the appointment of Ernst & Young as our independent registered public accounting firm, the Audit Committee will reconsider its appointment.

Required Vote. Approval of Proposal Two will require the affirmative vote of a majority of the shares present or represented by proxy and entitled to vote at the annual meeting.

Effect of Abstentions and Broker Non-Votes. Abstentions will be treated as votes against Proposal Two. Brokerage firms have authority to vote customers’ unvoted shares held by the firms in street name on Proposal Two. If a broker does not exercise this authority, such broker non-votes will have no effect on the results of this vote.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE TO RATIFY THE APPOINTMENT OF ERNST & YOUNG AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM, AND PROXIES RECEIVED BY THE BOARD OF DIRECTORS WILL BE VOTED IN FAVOR OF SUCH RATIFICATION UNLESS A STOCKHOLDER INDICATES OTHERWISE ON THE PROXY.

SOLICITATION

The cost of preparing and soliciting proxies will be borne by us. Solicitation on behalf of the Board of Directors will be made primarily by mail, but stockholders may be solicited by telephone, e-mail, other electronic means, or personal contact. Copies of materials for the annual meeting will be supplied to brokers, dealers, banks and voting trustees, or their nominees, for the purpose of soliciting proxies from beneficial owners.

OTHER MATTERS

The Board of Directors is not aware of any other business that will be presented to the annual meeting. If any other business is properly brought before the annual meeting, it is intended that proxies in the accompanying form will be voted in accordance with the judgment of the person or persons named in the proxies.
