Dear Common Unitholders of Navios Maritime Midstream Partners L.P.

We are pleased to inform you that on October 7, 2018, Navios Maritime Acquisition Corporation (“Navios Acquisition”) and its direct, wholly-owned subsidiary, NMA Sub LLC (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Navios Maritime Midstream Partners L.P. (“Navios Midstream”) and Navios Midstream Partners GP LLC (the “Navios Midstream GP”). Pursuant to the Merger Agreement, Merger Sub will be merged with and into Navios Midstream (the “Merger”), with Navios Midstream being a wholly-owned subsidiary of Navios Acquisition.

Under the terms of the Merger Agreement, each outstanding common unit representing limited partner interests in Navios Midstream (the “Navios Midstream Common Units”) that is held by a unitholder other than Navios Acquisition, Navios Midstream and their respective subsidiaries (such units, the “Navios Midstream Public Units”) will be converted into the right to receive, at the election of each holder of Navios Midstream Public Units, either (i) 0.42 shares of Navios Acquisition Common Stock (the “Common Stock Consideration”) or (ii) one share of series E convertible preferred stock, par value $0.0001 per share, of Navios Acquisition (the “Preferred Stock Consideration”).

The deadline for making an election will be 5:00 p.m. New York time on December 10, 2018, (unless Navios Acquisition provides notice of a later date). If a holder of Navios Midstream Public Units does not properly make an election by the election deadline, he or she will be deemed to have elected that form of Merger consideration (i.e., Common Stock Consideration or the Preferred Stock Consideration, referred to as the “Merger Consideration”) elected by the majority of Navios Midstream Public Units for which proper elections are made.

Moreover, if, pursuant to the election procedures in the Merger Agreement, holders of Navios Midstream Public Units elect (or are deemed to have elected as described above) to receive the Common Stock Consideration in respect of 80% or more of the Navios Midstream Public Units outstanding prior to the closing of the Merger, all outstanding Navios Midstream Public Units will be converted into the right to receive the Common Stock Consideration, and no Preferred Stock Consideration will be issued.

Neither the Conflicts Committee of Navios Midstream nor the Board of Directors of Navios Midstream has made any recommendation with respect to the form of Merger Consideration holders of Navios Midstream Public Units should elect to receive.

Each of the Conflicts Committee of Navios Midstream and the Board of Directors of Navios Midstream determined that the Merger Agreement and the transactions contemplated thereby, including the Merger, are in the best interests of Navios Midstream and the holders of Navios Midstream Public Units, and each approved and adopted the Merger Agreement. Additionally, each of the Conflicts Committee of Navios Midstream and the Board of Directors of Navios Midstream recommended the approval of the Merger Agreement and the transactions contemplated thereby, including the Merger, by the holders of Navios Midstream Common Units.

The approval and adoption of the Merger Agreement and the Merger by Navios Midstream requires the approval or consent of at least a majority of the outstanding Navios Midstream Common Units. Under the Merger Agreement, Navios Acquisition, which, as of November 14, 2018, beneficially owned 12,178,304 Navios Midstream Common Units or 58.1% of the outstanding Navios Midstream Common Units, has agreed to deliver a written consent adopting and approving in all respects the Merger Agreement and the transactions contemplated thereby, including the Merger, within two business days after the effectiveness of the registration statement of which this document is a part. The delivery by Navios Acquisition of a written consent with respect to the Navios Midstream Common Units it owns will be sufficient to adopt the Merger Agreement and thereby approve the Merger.

Shares of Navios Acquisition Common Stock are listed on the New York Stock Exchange (“NYSE”) under the trading symbol “NNA”. Navios Acquisition has agreed to use reasonable efforts to list shares of series E convertible preferred stock, par value $0.0001 per share, of Navios Acquisition (the “Navios Acquisition Series E Preferred Stock”) on the NYSE. Navios Acquisition will have no obligation to effect a listing of the Navios Acquisition Series E Preferred Stock unless holders of more than half of the Navios Midstream Public Units elect (or are deemed to have elected) to receive Preferred Stock Consideration and the NYSE permits such listing.

This information statement/prospectus provides you with detailed information about the Merger, the Common Stock Consideration, the Preferred Stock Consideration (and the designation, preferences and rights in respect thereof) and related matters. Navios Acquisition and Navios Midstream both encourage you to read the entire document carefully. In particular, please read the section entitled “Risk Factors” of this information statement/prospectus for a discussion of risks relevant to the Merger and the combined company.

NEITHER THE U.S. SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES COMMISSION HAS APPROVED OR DISAPPROVED OF THE SHARES OF NAVIOS ACQUISITION COMMON STOCK AND/OR NAVIOS ACQUISITION SERIES E PREFERRED STOCK TO BE ISSUED IN THE MERGER OR DETERMINED IF THIS INFORMATION STATEMENT/PROSPECTUS IS TRUTHFUL OR COMPLETE. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

The date of this information statement/prospectus is November 15, 2018 and it was first mailed to holders of Navios Midstream Common Units on or about November 16, 2018.

QUESTIONS AND ANSWERS

The following section provides brief answers to certain questions that you may have regarding the Merger Agreement and the Merger. Please note that this section does not address all issues that may be important to you as a holder of Navios Midstream Common Units. Accordingly, you should carefully read this entire information statement/prospectus, including each of the annexes, and the documents that have been incorporated into this information statement/prospectus.

Q. Why am I receiving these materials?

A. Pursuant to the terms of the Merger Agreement, if the Merger is consummated, Navios Midstream will become a wholly-owned subsidiary of Navios Acquisition. This information statement/prospectus is being provided by Navios Acquisition to holders of Navios Midstream Common Units in connection with the issuance of Common Stock Consideration or Preferred Stock Consideration to holders of Navios Midstream Public Units in accordance with the terms of the Merger Agreement.

This information statement/prospectus contains important information about the Merger Agreement, the Merger and the other transactions contemplated thereby, and you should read this information statement/prospectus carefully.

Q. What unitholder approval is required to adopt the Merger Agreement and approve the Merger?

A. The approval and adoption of the Merger Agreement and the transactions contemplated thereby, including the Merger, require the affirmative vote or consent of holders of at least a majority of the outstanding Navios Midstream Common Units. As of November 14, 2018, Navios Acquisition beneficially owned 12,178,304 Navios Midstream Common Units, amounting to 58.1% of the outstanding Navios Midstream Common Units. Under the terms of the Merger Agreement, Navios Acquisition agreed that, within two business days after the registration statement of which this information statement/prospectus is a part becomes effective, it will deliver a written consent adopting and approving in all respects the Merger Agreement and the transactions contemplated thereby, including the Merger. The delivery of a written consent by Navios Acquisition with respect to the Navios Midstream Common Units held by it will be sufficient to adopt the Merger Agreement and thereby approve the Merger. As a result, no further action by any other holder of Navios Midstream Common Units is required under applicable law or the Fifth Amended and Restated Agreement of Limited Partnership of Navios Midstream dated as of August 2, 2018 (which we refer to as the “Fifth Amended and Restated Limited Partnership Agreement”), and Navios Midstream will not solicit the vote of holders of Navios Midstream Common Units for the adoption of the Merger Agreement and the approval of the Merger, and will not call a special meeting of the holders of Navios Midstream Common Units for purposes of voting on the Merger Agreement and the Merger. We are not asking you for a proxy and you are requested not to send us a proxy.

Q. What will happen to Navios Midstream as a result of the Merger?

A. If the Merger is successfully completed, Merger Sub will be merged with and into Navios Midstream, with Navios Midstream becoming a wholly-owned subsidiary of Navios Acquisition.

Q. What will holders of Navios Midstream Common Units be entitled to receive in the Merger?

A. Navios Midstream Common Units that are not Navios Midstream Public Units will not receive any consideration in the Merger. Each Navios Midstream Public Unit will be converted into the right to receive, at the election of its holder, either:

1

If you do not properly make an election in respect of your Navios Midstream Public Units by sending in a properly completed election form mailed to each holder of Navios Midstream Public Units contemporaneously with this information statement/prospectus (which we refer to as the “Election Form”), together with the proper unit transfer documentation, prior to the election deadline set forth below, you will be deemed to have elected that form of consideration (i.e., Common Stock Consideration or Preferred Stock Consideration) elected by the majority of Navios Midstream Public Units for which proper elections are made.

It is important to note that a holder of Navios Midstream Public Units may not receive the form of consideration that he or she elects in the Merger. If, pursuant to the election procedures in the Merger Agreement, holders of Navios Midstream Public Units elect (or are deemed to have elected as described above) to receive the Common Stock Consideration in respect of 80% or more of the Navios Midstream Public Units outstanding prior to the closing of the Merger, all outstanding Navios Midstream Public Units will be converted into the right to receive the Common Stock Consideration and no Preferred Stock Consideration will be issued in the Merger. For additional information regarding the election procedures, please read the section entitled “The Merger — Procedure for Election and Exchange of Navios Midstream Common Units for Merger Consideration.”

Q. Does the Board of Directors of Navios Midstream (which we refer to as the “Navios Midstream Board”) or the Conflicts Committee of the Navios Midstream Board (which we refer to as the “Navios Midstream Conflicts Committee”) recommend that I elect the Common Stock Consideration or the Preferred Stock Consideration?

A. The Navios Midstream Board and the Navios Midstream Conflicts Committee make no recommendation as to whether any holder of Navios Midstream Public Units should elect to receive the Common Stock Consideration or the Preferred Stock Consideration.

Q. Can I make one election for some of my Navios Midstream Public Units and another election for the rest?

A. Yes. You may submit an election form (which we refer to as an “Election Form”) in which you elect Common Stock Consideration with respect to a portion, and Preferred Stock Consideration with respect to a portion, of your Navios Midstream Public Units.

Q. Can I change my election after I submit an Election Form?

A. Yes. You may revoke your election to receive either the Common Stock Consideration or Preferred Stock Consideration by delivering written notice of your revocation to the exchange agent prior to the election deadline set forth below. You may change your election by delivering a properly completed revised Election Form that identifies the Navios Midstream Public Units to which the revised Election Form applies. Delivery of a revised Election Form with respect to any Navios Midstream Public Units, prior to the election deadline, will result in the revocation of all prior Election Forms with respect to those identified Navios Midstream Public Units. You will not be entitled to revoke or change your election following the election deadline.

Q. Where will Navios Acquisition Common Stock trade after the Merger?

A. It is anticipated that Navios Acquisition Common Stock issued in the Merger will trade on the New York Stock Exchange (which we refer to as the “NYSE”) under the symbol “NNA”.

Q. Will the Navios Acquisition Series E Preferred Stock trade on an exchange?

A. Navios Acquisition will use reasonable efforts to cause the Navios Acquisition Series E Preferred Stock to be approved for listing on the NYSE. No listing of the Navios Acquisition Series E Preferred Stock will occur if either (i) the listing is not permitted by the NYSE or (ii) holders of 50% or fewer of the Navios Midstream Public Units elect (or are deemed to have elected) to receive Preferred Stock Consideration.

2

Q. Is a vote of the Navios Acquisition stockholders required in order for Navios Acquisition to issue shares of Navios Acquisition Series E Preferred Stock?

A. No. Under the amended and restated articles of incorporation of Navios Acquisition, the board of directors of Navios Acquisition (which we refer to as the “Navios Acquisition Board”) is expressly granted the authority to issue shares of preferred stock, with such voting powers, designations, preferences and other special rights, qualifications, limitations and restrictions as the Navios Acquisition Board may determine, approve and adopt.

Q. When will the Merger be completed?

A. Navios Acquisition and Navios Midstream expect the closing to occur on or about December 13, 2018, subject to satisfaction of the conditions to closing. Please read the section entitled “The Merger Agreement — Conditions to the Merger.”

Q. What are the expected U.S. federal income tax consequences of the Merger to holders of Navios Midstream Public Units?

A. It is intended that, for United States federal income tax purposes, the Merger will qualify as a “reorganization” within the meaning of Section 368(a) of the United States Internal Revenue Code of 1986, as amended (which we refer to as the “Code”). However, the completion of the Merger is not conditioned upon the receipt of an opinion of counsel to the effect that the Merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code. You should read the section entitled “Material U.S. Federal Income Tax Consequences of the Merger” and consult your own tax advisors regarding the United States federal income tax consequences of the Merger to you in your particular circumstances, as well as tax consequences arising under the laws of any state, local or non-United States taxing jurisdiction.

Q. How do holders of Navios Midstream Public Units make their election to receive the Common Stock Consideration or Preferred Stock Consideration in exchange for their Navios Midstream Public Units? What if a holder of Navios Midstream Public Units fails to properly make an election?

A. Contemporaneously with the mailing of this information statement/prospectus, an Election Form is being mailed to each holder of Navios Midstream Public Units. The Election Form sets forth detailed instructions on how to make an election with respect to the form of Merger Consideration you may receive for your Navios Midstream Public Units. The deadline for submitting a properly completed Election Form together with the proper unit transfer documentation will be 5:00 p.m. New York time on December 10, 2018, but may be extended (which we refer to as the “Election Deadline”). Navios Acquisition will use reasonable efforts to issue a press release at least five business days prior to the Election Deadline and if the Election Deadline is subsequently extended, at least one business day prior to any extended Election Deadline. You must return the completed Election Form along with properly completed unit transfer documentation, according to the instructions included with the Election Form to the exchange agent prior to the Election Deadline and you will receive your Merger Consideration following the closing of the Merger, after the exchange agent receives your completed Election Form, certificates (if any) and/or such other documents as may be required by the Election Form or the exchange agent. If you do not submit a properly completed Election Form together with the proper unit transfer documentation by the Election Deadline, then following the Merger, you will receive a letter of transmittal and instructions on how to obtain the Merger Consideration you will be entitled to receive in exchange for your Navios Midstream Public Units. You must return the completed letter of transmittal and surrender your certificates (if any), and you will receive your Merger consideration after the exchange agent receives your completed letter of transmittal, certificates (if applicable) and/or such other documents that may be required by the exchange agent.

If you own Navios Midstream Public Units in “street name” through a bank, broker or other nominee and you wish to make an election, you should seek instructions from the bank, broker or other nominee holding your units concerning how to make an election.

Q. What if my Navios Midstream Public Units are certificated, but I cannot find the certificates?

A. There will be a procedure for you to receive the Merger Consideration in the Merger, even if you have lost one or more of your certificates (if any) for the Navios Midstream Public Units. This procedure, however, may take time to complete. In order to ensure that you will be able to receive the Merger Consideration promptly after the Merger is completed, if your Navios Midstream Public Units are certificated, but you cannot locate your certificates after looking for them carefully, we urge you to contact Morrow Sodali, as soon as possible and follow the procedures they explain to you for replacing your certificates for the Navios Midstream Public Units. Morrow Sodali can be reached at (800) 662-5200 or on their website at www.morrowsodali.com and at the email address NAPinfo@morrowsodali.com, or you can write them at 509 Madison Avenue, Suite 1608, New York, NY 10022.

Q. Are there any risks that I should consider?

A. Yes. There are risks associated with all business combinations, including the Merger. There are also risks associated with Navios Acquisition’s business and the ownership of Navios Acquisition Common Stock and Navios Acquisition Series E Preferred Stock. We have described certain of these risks and other risks in more detail in the section entitled “Risk Factors.”

Q. Are holders of Navios Midstream Public Units entitled to appraisal rights?

A. No. Holders of Navios Midstream Public Units do not have appraisal rights under applicable law or contractual appraisal rights under the Merger Agreement.

Q. Why did the Navios Acquisition Board approve the 15:1 reverse stock split in respect of the Navios Acquisition Common Stock (which we refer to as the “Reverse Stock Split”), and when was it announced?

A. Navios Acquisition has been unable to satisfy the NYSE listing requirement of trading above one dollar for a period of thirty consecutive trading days in respect of the Navios Acquisition Common Stock. The Reverse Stock Split enables Navios Acquisition to comply with this particular listing requirement. The Reverse Stock Split was initially announced by Navios Acquisition on October 8, 2018.

Q. Is the Reverse Stock Split now effective?

A. Yes. The Reverse Stock Split, which was approved by holders of Navios Acquisition Common Stock at a special meeting held on November 9, 2018, took effect on November 14, 2018. The references in this information statement/prospectus to 0.42 of a share of Navios Acquisition Common Stock constituting the Common Stock Consideration and 0.34 of a share of Navios Acquisition Common Stock into which Navios Acquisition Series E Preferred Stock will be convertible, both give effect to the Reverse Stock Split.

Q. Who do I call if I have further questions about the Merger Agreement or the Merger?

A. Holders of Navios Midstream Public Units may call Navios Midstream’s Investor Relations Department at (212) 906-8647 if they have further questions or if they would like additional copies, without charge, of this information statement/prospectus.

RISK FACTORS

The Merger, the Navios Acquisition business, and owning Navios Acquisition Common Stock or Navios Acquisition Series E Preferred Stock involve a high degree of risk. In addition to the other information contained in this information statement/prospectus, including the matters under the section entitled “Cautionary Note Regarding Forward-Looking Statements,” you should carefully consider all of the following risk factors relating to the Merger, the Navios Acquisition business and shares of Navios Acquisition’s Common Stock, Capital Structure and Indebtedness after the Merger.

Risks Related to the Merger

Because the market price of shares of Navios Acquisition Common Stock may fluctuate, you cannot be certain of the precise value of the Common Stock Consideration that you will receive in the Merger or, if you have elected to receive the Preferred Stock Consideration, the precise value of the Navios Acquisition Common Stock that you will receive upon a conversion of Navios Acquisition Series E Preferred Stock into Navios Acquisition Common Stock.

The value of the Common Stock Consideration to be received at closing will vary depending on the market price of shares of Navios Acquisition Common Stock on the date of the closing of the Merger.

Similarly, the value of the Navios Acquisition Series E Preferred Stock will vary, depending on the market price of shares of the Navios Acquisition Common Stock on the date that the Series E Preferred Stock is converted, automatically or voluntarily, into Navios Acquisition Common Stock.

In addition, the price of shares of Navios Acquisition Common Stock and the price of Navios Midstream Common Units at the Effective Time may vary from their respective prices on the date the Merger Agreement was executed and on the date of this information statement/prospectus. There is no “price protection” mechanism contained in the Merger Agreement that would adjust the number of Navios Acquisition Common Stock or Navios Acquisition Series E Preferred Stock that holders of Navios Midstream Public Units will receive based on any decreases in the trading price of Navios Acquisition Common Stock.

These variations in Navios Acquisition Common Stock and Navios Midstream Common Unit prices may be the result of various factors, including:

The market price for Navios Acquisition Common Stock or the Navios Acquisition Series E Preferred Stock may be affected by factors different from those affecting the Navios Midstream Common Units.

Upon completion of the Merger, holders of shares of Navios Midstream Public Units will become holders of shares of Navios Acquisition Common Stock or Navios Acquisition Series E Preferred Stock subject to submitting an Election Form or letter of transmittal, as applicable, to the exchange agent. Some of Navios Midstream’s businesses differ from those of Navios Acquisition, and accordingly the results of operations of

23

Navios Acquisition will be affected by some factors that are different from those currently affecting the results of operations of Navios Midstream. For a discussion of the businesses of Navios Acquisition and Navios Midstream and of other factors to consider in connection with those businesses, you should carefully review the documents included as Annexes to this information statement/prospectus.

If you elect (or are deemed to have elected) to receive Preferred Stock Consideration instead of Common Stock Consideration in connection with the Merger, you will receive, upon a subsequent conversion of each share of Navios Acquisition Series E Preferred Stock into Navios Acquisition Common Stock, a lower number of shares of Navios Acquisition Common Stock than you would have otherwise received had you elected to receive the Common Stock Consideration.

In connection with the Merger, each Navios Midstream Public Unit is exchangeable for 0.42 shares of Navios Acquisition Common Stock, or one share of Navios Acquisition Series E Preferred Stock. Notwithstanding the fact that the Navios Midstream Public Units and the shares of Navios Acquisition Series E Preferred Stock are exchangeable on a 1:1 basis, once issued, each Navios Acquisition Series E Preferred Stock is convertible into 0.34 of a share of Navios Acquisition Common Stock. The lower conversion ratio takes into account, among other things, the fact that the Navios Acquisition Series E Preferred Stock has a liquidation preference over the Navios Acquisition Common Stock in the event of a liquidation of Navios Acquisition.

It is possible that no Navios Acquisition Series E Preferred Stock will be issued in the Merger.

If holders of Navios Acquisition Public Units elect (or are deemed to have elected) to receive the Common Stock Consideration in respect of 80% or more of the Navios Midstream Public Units outstanding prior to the closing of the Merger, all outstanding Navios Midstream Public Units will be converted into the right to receive the Common Stock Consideration and no Preferred Stock Consideration will be issued in the Merger.

Even if issued, the Navios Acquisition Series E Preferred Stock may not be listed on any stock exchange.

Pursuant to the Merger Agreement, Navios Acquisition will use reasonable efforts to cause the Navios Acquisition Series E Preferred Stock to be approved for listing on the NYSE. No listing of the Navios Acquisition Series E Preferred Stock will occur if either (i) the listing is not permitted by the NYSE or (ii) holders of 50% or fewer of the Navios Midstream Public Units elect (or are deemed to have elected) to receive Preferred Stock Consideration. Even if the Navios Acquisition Series E Preferred Stock is listed on the NYSE, trading liquidity for the Navios Acquisition Series E Preferred Stock may be lower than that of Navios Acquisition Common Stock.

Certain of the executive officers and members of the Navios Midstream Board have interests that are different from, and/or in addition to, the interests of interests of holders of Navios Midstream Common Units.

Some of the members of the Navios Midstream Board and certain of Navios Midstream’s executive officers have financial interests in the Merger that are in addition to, and/or different from, the interests of holders of Navios Midstream Common Units, but only with respect to indemnification and insurance coverage. In particular, the Merger Agreement provides for director and officer indemnification arrangements for each of Navios Midstream’s directors and officers and provides existing directors’ and officers’ liability insurance to the Navios Midstream directors and officers that will continue for six years following completion of the Merger. With the exception of two directors who collectively hold fewer than 1,900 shares of Navios Midstream Common Units, none of the officers or directors of Navios Midstream own any Navios Midstream Common Units or any other securities of Navios Midstream. For a detailed discussion of the interests that Navios Midstream’s directors and executive officers have in the Merger, please see the section entitled “The Merger — Interests of Navios Midstream’s Directors and Officers in the Merger.”

24

The Merger is subject to closing conditions that, if not satisfied or waived, will result in the Merger not being consummated.

The obligation of the parties to the Merger Agreement to complete the Merger is subject to the satisfaction or waiver of certain conditions, including, among others:

The parties’ obligations are also separately subject to the satisfaction or waiver of the following conditions:

If these conditions are not satisfied or waived, the Merger will not occur, which may cause the market price of the Navios Midstream Common Units to decline.

Financial projections regarding Navios Acquisition and Navios Midstream may not prove accurate.

In performing their financial analyses and rendering their fairness opinions, the financial advisor to the Navios Midstream Conflicts Committee reviewed and relied on, among other things, internal financial analyses and forecasts for Navios Acquisition and Navios Midstream. These financial projections include assumptions of

25

Navios Acquisition and Navios Midstream, including with regards to future operating cash flows, expenditures and income. These financial projections were not prepared with a view toward public disclosure or toward compliance with GAAP, the published guidelines of the SEC, or the guidelines established by the American Institute of Certified Public Accountants. The financial projections should not be regarded as an indication that Navios Acquisition, Navios Midstream, or their respective representatives considered or consider the projections to be a reliable or accurate prediction of future performance. The financial projections are subject to significant economic, competitive, industry and other uncertainties and may not be achieved in full, at all or within projected timeframes. The failure of Navios Acquisition or Navios Midstream to achieve projected results, including projected cash flows, could have a material adverse effect on the price of Navios Midstream Common Units, its financial position and its ability to maintain or increase its distributions following the Merger.

The successful execution of the integration strategy following the consummation of the Merger will involve risks and may not be successful.

The success of the Merger will depend, in part, on the ability of the combined company to realize the anticipated benefits from combining Navios Acquisition’s and Navios Midstream’s businesses. Realizing the benefits of the Merger will depend in part on the integration of assets, operations, functions and personnel while maintaining adequate focus on the core businesses of the combined company. Any expected cost savings, economies of scale, enhanced liquidity or other operational efficiencies, as well as revenue enhancement opportunities anticipated from the combination of Navios Acquisition and Navios Midstream, or other synergies, may not occur.

The combined company’s management team will face challenges inherent in efficiently managing an increased number of employees over larger geographic distances, including the need to implement appropriate systems, policies, benefits and compliance programs. If management of the combined company is unable to minimize the potential disruption of the combined company’s ongoing business caused by the integration efforts and the distraction of management during the integration process, the anticipated benefits of the Merger may not be realized or may only be realized to a lesser extent than expected. In addition, the inability to successfully manage the implementation of appropriate systems, policies, benefits and compliance programs for the combined company could have an adverse effect on the combined company after the Merger. These integration-related activities also could have an adverse effect on each of Navios Acquisition and Navios Midstream pending the completion of the Merger.

It is possible that the integration process could result in the loss of key employees, as well as the disruption of each of Navios Acquisition’s and Navios Midstream’s ongoing businesses or the creation of inconsistencies between Navios Acquisition’s and Navios Midstream’s standards, controls, procedures and policies. Any or all of those occurrences could adversely affect the combined company’s ability to maintain relationships with service providers, customers and employees after the Merger or to achieve the anticipated benefits of the Merger.

The combined company’s operating expenses may increase significantly over the near term due to the increased headcount, expanded operations and expenses or other changes related to the Merger. In addition, the actual integration may result in additional and unforeseen expenses, which could reduce the anticipated benefits of the Merger and materially and adversely affect the combined company’s business, operating results and financial condition.

Risk Factors Relating to the Shipping Industry and the Operation of Navios Acquisition’s Vessels

Navios Acquisition’s international activities increase the compliance risks associated with economic and trade sanctions imposed by the United States, the European Union and other jurisdictions.

Navios Acquisition’s international operations and activities could expose it to risks associated with trade and economic sanctions, prohibitions or other restrictions imposed by the United States or other governments or organizations, including the United Nations, the European Union and its member countries. Under economic and

26

trade sanctions laws, governments may seek to impose modifications to, prohibitions/restrictions on business practices and activities, and modifications to compliance programs, which may increase compliance costs, and, in the event of a violation, may subject Navios Acquisition to fines and other penalties.

Iran

During the last few years prior to January 2016, the scope of sanctions imposed against Iran, the government of Iran and persons engaging in certain activities or doing certain business with and relating to Iran was expanded by a number of jurisdictions, including the United States, the European Union and Canada. In 2010, the United States enacted the Comprehensive Iran Sanctions Accountability and Divestment Act (which we refer to as “CISADA”), which expanded the scope of the former Iran Sanctions Act. The scope of U.S. sanctions against Iran were expanded subsequent to CISADA by, among other U.S. laws, the National Defense Authorization Act of 2012 (which we refer to as the “2012 NDAA”), the Iran Threat Reduction and Syria Human Rights Act of 2012 (which we refer to as “ITRA”), Executive Order 13662, and the Iran Freedom and Counter-Proliferation Act of 2012 (which we refer to as “IFCA”). The foregoing laws, among other things, expanded the application of prohibitions to non-U.S. companies, such as Navios Acquisition, and introduced limits on the ability of non-U.S. companies and other non-U.S. persons to do business or trade with Iran when such activities relate to specific trade and investment activities involving Iran.

U.S. economic sanctions on Iran fall into two general categories: “Primary” sanctions, which prohibit U.S. persons or U.S. companies and their foreign branches, U.S. citizens, U.S. permanent residents, and persons within the territory of the United States from engaging in all direct and indirect trade and other transactions with Iran without U.S. government authorization, and “secondary” sanctions, which are mainly nuclear-related sanctions.

Most of the EU and U.S. nuclear-related sanctions with respect to Iran (including, inter alia, CISADA, ITRA, and IFCA) were suspended in 2016 through the implementation of the Joint Comprehensive Plan of Action (the “JCPOA”) entered into between the permanent members of the United Nations Security Council (China, France, Russia, the United Kingdom and the United States) and Germany. However, some of these U.S. (secondary) sanctions have been reimposed effective August 7, 2018 as a result of the withdrawal of the United States from the JCPOA, and the remainder of these U.S. (secondary) sanctions are scheduled to be reimposed effective November 5, 2018.

EU sanctions remain in place in relation to the export of arms and military goods, missiles-related goods and items that might be used for internal repression. The main nuclear-related EU sanctions which remain in place include restrictions on:

Dealing with the above is no longer prohibited, but prior authorization must be obtained first and is granted on a case-by-case basis. The remaining restrictions apply to related actions, including the sale, supply, transfer or export, directly or indirectly to any Iranian person/for use in Iran, as well as the provision of technical assistance, financing or financial assistance in relation to the restricted activity. Certain individuals and entities remain sanctioned and the prohibition to make available, directly or indirectly, economic resources or assets to or for the benefit of sanctioned parties remains. “Economic resources” is widely defined and it remains prohibited to

27

provide vessels for a fixture from which a sanctioned party (or parties related to a sanctioned party) directly or indirectly benefits. It is therefore still necessary to carry out due diligence on the parties and cargoes involved in fixtures involving Iran.

Russia/Ukraine

As a result of the crisis in Ukraine and the annexation of Crimea by Russia in 2014, both the United States and the European Union have implemented sanctions against certain persons and entities.

The European Union has imposed travel bans and asset freezes on certain persons and entities pursuant to which it is prohibited to make available, directly or indirectly, economic resources or assets to or for the benefit of the sanctioned parties. Certain Russian ports including Kerch Commercial Seaport; Sevastopol Commercial Seaport and Port Feodosia are subject to the above restrictions. Other entities are subject to sectoral sanctions which limit the provision of equity and debt financing to the listed entities. In addition, various restrictions on trade have been implemented which, amongst others, include a prohibition on the import into the European Union of goods originating in Crimea or Sevastopol as well as restrictions on trade in certain dual-use and military items and restrictions in relation to various items of technology associated with the oil industry for use in deep water exploration and production, Arctic oil exploration and production or shale oil projects in Russia. As such, it is important to carry out due diligence on the parties and cargoes involved in fixtures relating to Russia.

The U.S. has imposed sanctions against certain designated Russian entities and individuals (which we refer to as “U.S. Russian Sanctions Targets”). These sanctions block the property and all interests in property of the U.S. Russian Sanctions Targets. This effectively prohibits U.S. persons from engaging in any economic or commercial transactions with the U.S. Russian Sanctions Targets unless the same are authorized by the U.S. Treasury Department. Similar to EU sanctions, U.S. sanctions also entail restrictions on certain exports from the United States to Russia and the imposition of Sectoral Sanctions which restrict the provision of equity and debt financing to designated Russian entities. While the prohibitions of these sanctions are not directly applicable to Navios Acquisition, Navios Acquisition has compliance measures in place to guard against transactions with U.S. Russian Sanctions Targets which may involve the United States or U.S. persons and thus implicate prohibitions. The United States also maintains prohibitions on trade with Crimea.

The U.S.’s “Countering America’s Adversaries Through Sanctions Act” (Public Law 115-44) (CAATSA), authorizes imposition of new sanctions on Iran, Russia, and North Korea. These sanctions prohibit a variety of activities involving Russia.

Venezuela-Related Sanctions

The U.S. sanctions with respect to Venezuela prohibit dealings with designated Venezuelan government officials, and curtail the provision of financing to PDVSA and other government entities. EU sanctions against Venezuela are primarily governed by EU Council Regulation 2017/2063 of November 13, 2017 concerning restrictive measures in view of the situation in Venezuela. This includes financial sanctions and restrictions on listed persons, an arms embargo, and related prohibitions and restrictions including restrictions related to internal repression.

Other U.S. Economic Sanctions and Sanctions Targets

In addition to Iran and certain Russian entities and individuals, as indicated above, the United States maintains economic sanctions against Syria, Cuba, North Korea, and sanctions against entities and individuals (such as entities and individuals in the foregoing targeted countries, designated terrorists, narcotics traffickers) whose names appear on the List of SDNs and Blocked Persons maintained by the U.S. Treasury Department (which we refer to, collectively as, the “Sanctions Targets”). Navios Acquisition is subject to the prohibitions of these sanctions to the extent that any transaction or activity that Navios Acquisition engages in involves Sanctions Targets and a U.S. person or otherwise has a nexus to the United States.

28

Other EU Economic Sanctions Targets

The European Union also maintains sanctions against Syria, North Korea and certain other countries and against individuals listed by the EU. These restrictions apply to Navios Acquisition’s operations and as such, to the extent that these countries may be involved in any business it is important to carry out checks to ensure compliance with all relevant restrictions and to carry out due diligence checks on counterparties and cargoes.

Compliance

Considering the aforementioned prohibitions of U.S. as well as EU sanctions and the nature of Navios Acquisition’s business, there is a sanctions risk for it due to the worldwide trade of Navios Acquisition’s vessels, which Navios Acquisition seeks to minimize by following Navios Acquisition’s corporate written Economic Sanctions Compliance Policy and Procedures and Navios Acquisition’s compliance with all applicable sanctions and embargo laws and regulations. Although Navios Acquisition intends to maintain such compliance, there can be no assurance that Navios Acquisition will be in compliance in the future, particularly as the scope of certain laws may be unclear and may be subject to changing interpretations, and the law may change. Moreover, despite, for example, relevant provisions in charter agreements forbidding the use of Navios Acquisition’s vessels in trade that would violate economic sanctions, Navios Acquisition’s charterers may nevertheless violate applicable sanctions and embargo laws and regulations and those violations could in turn negatively affect Navios Acquisition’s reputation and be imputed to Navios Acquisition. In addition, given Navios Acquisition’s relationship with the affiliates and subsidiaries of Navios Holdings, Navios Acquisition cannot give any assurance that an adverse finding against any of the affiliates and subsidiaries of Navios Holdings by a governmental or legal authority with respect to the matters discussed herein or any future matter related to regulatory compliance by Navios Acquisition or the affiliates and subsidiaries of Navios Holdings, will not have a material adverse impact on Navios Acquisition’s business, reputation or the market price or trading of the Navios Acquisition Common Units.

Navios Acquisition is constantly monitoring developments in the United States, the European Union and other jurisdictions that maintain economic sanctions against Iran, other countries, and other sanctions targets, including developments in implementation and enforcement of such sanctions programs. Expansion of sanctions programs, embargoes and other restrictions in the future (including additional designations of countries and persons subject to sanctions), or modifications in how existing sanctions are interpreted or enforced, could prevent Navios Acquisition’s vessels from calling in ports in sanctioned countries or could limit their cargoes. If any of the risks described above materialize, it could have a material adverse impact on Navios Acquisition’s business and results of operations.

To reduce the risk of violating economic sanctions, Navios Acquisition has a policy of compliance with applicable economic sanctions laws and have implemented and continue to implement and diligently follow compliance procedures to avoid economic sanctions violations.

Navios Acquisition could be materially adversely affected by violations of the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act and anti-corruption laws in other applicable jurisdictions.

Navios Acquisition is subject to anti-corruption, anti-bribery, anti-money laundering and similar laws and regulations in various jurisdictions in which Navios Acquisition conducts activities, including the U.S. Foreign Corrupt Practices Act (which we refer to “FCPA”), and other anti-corruption laws and regulations. In addition, Navios Acquisition may be subject to the U.K. Bribery Act 2010. The FCPA and the U.K. Bribery Act 2010 prohibit Navios Acquisition and its officers, directors, employees and business partners acting on its behalf, including agents, from corruptly offering, promising, authorizing or providing anything of value to a “foreign official” for the purposes of influencing official decisions or obtaining or retaining business or otherwise obtaining favorable treatment. The FCPA also requires companies to make and keep books, records and accounts that accurately reflect transactions and dispositions of assets and to maintain a system of adequate internal accounting controls. The UK Bribery Act also prohibits non-governmental “commercial” bribery and soliciting or accepting bribes. A violation of these laws or regulations could adversely affect Navios Acquisition’s business, results of operations, financial condition and reputation.

29

As an international shipping company, Navios Acquisition operates in countries known to present heightened risks for corruption. In addition, Navios Acquisition’s business requires it to interact with government officials, including port officials, harbor masters, maritime regulators, customs officials and pilots, and we have client relationships with state-owned enterprises. Both factors raise the risk of anticorruption issues.

Non-compliance with anti-corruption, anti-bribery or anti-money laundering laws could subject Navios Acquisition to whistleblower complaints, adverse media coverage, investigations, and severe administrative, civil and criminal sanctions, collateral consequences, remedial measures and legal expenses, all of which could materially and adversely affect Navios Acquisition’s business, results of operations, financial condition and reputation. Compliance with the FCPA, the U.K. Bribery Act and other applicable anti-corruption laws and related regulations and policies imposes potentially significant costs and operational burdens on Navios Acquisition. Although Navios Acquisition has policies and procedures in place to mitigate the risk of non-compliance with anti-corruption, anti-bribery or anti-money laundering laws, including Navios Acquisition’s Code of Ethics and anti-bribery and anti-corruption policy, Navios Acquisition may not be able to adequately prevent or detect all possible violations under applicable anti-bribery and anti-corruption legislation, including by third-party agents.

33

THE MERGER

Description of the Merger

On October 7, 2018, Navios Acquisition and Navios Midstream agreed to combine businesses by merging Merger Sub, a wholly owned subsidiary of Navios Acquisition, with and into Navios Midstream. If the Merger is successfully consummated, Navios Midstream will become a wholly owned subsidiary of Navios Acquisition.

As a result of the Merger, each Navios Midstream Public Unit will be converted into the right to receive, at the election of each holder of Navios Midstream Public Units, either:

Each holder of Navios Midstream Public Units will be mailed an Election Form to make an election whether to receive, with respect to each Navios Midstream Public Unit, either the Common Stock Consideration or the Preferred Stock Consideration. For each Navios Midstream Public Unit in respect of which no election is made by the holder thereof (or in respect of which a properly completed Election Form is not submitted), the holder will be deemed to have elected to receive the form of consideration (i.e., Common Stock Consideration or the Preferred Stock Consideration) elected by the majority of Navios Midstream Public Units for which proper elections are made.

If holders elect (or are deemed to have elected) to receive the Common Stock Consideration in respect of 80% or more of the Navios Midstream Public Units outstanding prior to the closing of the Merger, all outstanding Navios Midstream Public Units will be converted into the right to receive the Common Stock Consideration and no Preferred Stock Consideration will be issued in the Merger.

The approval and adoption of the Merger Agreement and the Merger by Navios Midstream requires the approval or consent of at least a majority of the outstanding Navios Midstream Common Units. Pursuant to the terms of the Merger Agreement, Navios Acquisition which, as of November 14, 2018, beneficially owned 12,178,304 Navios Midstream Common Units or 58.1% of the outstanding Navios Midstream Common Units, has agreed to deliver a written consent, adopting and approving in all respects the Merger Agreement and the transactions contemplated thereby, including the Merger. The delivery by Navios Acquisition of a written consent with respect to the Navios Midstream Common Units it owns will be sufficient to adopt the Merger Agreement and thereby approve the Merger.

For additional and more detailed information regarding the legal documents that govern the Merger, including information about the conditions to the completion of the Merger and the provisions for terminating or amending the Merger Agreement, please read the section entitled “The Merger Agreement.”

Navios Acquisition’s Ownership Interest in and Control of Navios Midstream

Holders of Navios Midstream Common Units should be aware that Navios Acquisition is the sole member of Navios Midstream GP and currently owns 12,178,304 Navios Midstream Common Units, representing 58.1% of the outstanding Navios Midstream Common Units. In addition, Navios Acquisition indirectly owns all of the 427,499 general partner units of Navios Midstream and all of the Navios Midstream incentive distribution rights.

Navios Acquisition’s ability, as sole member of Navios Midstream GP, to control the appointment of three of the seven members of the Navios Midstream Board and to approve certain significant actions Navios Midstream may take, in addition to Navios Acquisition’s ownership of a majority of the outstanding Navios Midstream Common Units means that Navios Acquisition, together with its affiliates, may have the ability to exercise influence regarding the management of Navios Midstream.

34

Certain persons associated with Navios Midstream have a relationship with Navios Acquisition. Angeliki Frangou, who serves as Chairman of the Navios Midstream Board and Chief Executive Officer of Navios Midstream, also serves as Chairman of the Navios Acquisition Board and Chief Executive Officer of Navios Acquisition. Vasiliki Papaefthymiou, who serves as the Secretary of Navios Midstream, also serves as the Secretary of Navios Acquisition. Certain of the foregoing persons also serve as officers, directors and/or members of certain affiliates of Navios Midstream and/or Navios Acquisition.

Background of the Transaction

The Navios Acquisition Board regularly reviews operational and strategic opportunities to maximize value for holders of Navios Acquisition Common Stock. The Navios Midstream Board similarly regularly reviews operational and strategic opportunities to maximize value for holders of Navios Midstream Common Units.

On June 28, 2018, Angeliki Frangou, as Chairman of the Navios Acquisition Board, contacted Alex Kalafatides, Christos Kokkinis and Vasilios Mouyis, being the members of the Navios Midstream Conflicts Committee (which is a standing committee of the Navios Midstream Board) and shared with them a letter from Navios Acquisition to the Navios Midstream Board in which Navios Acquisition proposed a transaction in which Navios Midstream would be combined with Navios Acquisition and each Navios Midstream Public Unit would be exchanged for 6.292 newly issued shares of Navios Acquisition Common Stock. At the time, the proposed exchange ratio represented a 1% premium over the most recent closing trading price of Navios Midstream Common Units.

In light of the fact that a subsidiary of Navios Acquisition serves as the general partner of Navios Midstream and Navios Acquisition owns approximately 58.1% of the outstanding Navios Midstream Common Units (and the fact that Ms. Frangou serves as Chairman and Chief Executive Officer of both Navios Acquisition and Navios Midstream), Ms. Frangou, in her capacity as Chairman of the Navios Midstream Board, requested that Mr. Kalafatides and the Navios Midstream Conflicts Committee (i) (A) review, evaluate and negotiate with Navios Acquisition a proposed transaction (which we refer to as the “Proposed Transaction”) and related arrangements and agreements on behalf of Navios Midstream and its subsidiaries and the holders of Navios Midstream Public Units, (B) make a recommendation to the Navios Midstream Board whether to approve the Proposed Transaction and related arrangements and agreements and (C) determine whether to approve the Proposed Transaction and related arrangements and agreements by Special Approval (as defined below in the section titled “The Merger — Resolution of Conflicts of Interest; Standards of Conduct and Modification of Duties”), (ii) negotiate, or delegate to any authorized person the authority to negotiate, any terms of the Proposed Transaction and related arrangements and agreements as it may deem necessary or appropriate, in its sole discretion and (iii) consult with management of Navios Midstream in conection with discussions and/or negotiations concerning potential terms and conditions of the Proposed Transaction and related arrangements and agreements.

On June 28, 2018, Navios Acquisition issued a press release announcing the proposal it made to the Navios Midstream Board and disclosed its proposed terms in an amendment to Navios Acquisition’s Schedule 13D filed with the SEC on the same date.

The Navios Midstream Conflicts Committee interviewed several potential outside legal and financial advisors to advise the Navios Midstream Conflicts Committee in connection with evaluating and negotiating the Proposed Transaction. Following the interviews, the Navios Midstream Conflicts Committee decided to engage Latham & Watkins LLP (which we refer to as “Latham”) as legal counsel and Piper Jaffray as financial advisor because of each advisor’s knowledge, expertise and experience with public merger and acquisition transactions, particularly those involving master limited partnerships, and conflicts committee engagements.

On July 9, 2018, the Navios Midstream Conflicts Committee met telephonically. At the meeting, representatives of Latham discussed with the Navios Midstream Conflicts Committee their duties in, and best

35

practices for, carrying out their evaluation, negotiation and review process for the Proposed Transaction. Representatives from Piper Jaffray discussed the due diligence process with the Navios Midstream Conflicts Committee and the financial information that would be appropriate for a preliminary evaluation of the Proposed Transaction.

On July 25, 2018, the Navios Midstream Conflicts Committee met telephonically with representatives from Latham and Piper Jaffray. Representatives from Piper Jaffray presented Piper Jaffray’s initial analysis of the Proposed Transaction, which included a review of the due diligence performed to date, assumptions used in its financial modeling, a summary of the valuation methodologies employed, a preliminary valuation of Navios Acquisition, a preliminary valuation of Navios Midstream, a financial overview of the pro forma combined company and a preliminary analysis of the terms and conditions of the Proposed Transaction. The Navios Midstream Conflicts Committee then engaged in a discussion of the various components of the presentation, including the value that would be received by the holders of Navios Midstream Public Units under Navios Acquisition’s proposal.

The Navios Midstream Conflicts Committee met telephonically with Piper Jaffray and Latham on August 6, 2018 to discuss Piper Jaffray’s updated analysis of the Proposed Transaction, including its updated valuation of Navios Acquisition Common Stock. Representatives of Piper Jaffray discussed with the Navios Midstream Conflicts Committee the possibility of counter-proposing an increase in the exchange ratio, payment of all or a portion of the consideration in cash or payment of the consideration in the form of convertible preferred stock of Navios Acquisition. The Navios Midstream Conflicts Committee discussed these alternative approaches to the counter-proposal.

From August 6, 2018 until August 28, 2018, the Navios Midstream Conflicts Committee, Latham and Piper Jaffray continued to perform due diligence and Piper Jaffray continued its financial analysis of the Proposed Transaction. At various times during this period, the Navios Midstream Conflicts Committee discussed with its advisors the various components of the Proposed Transaction and the alternative approaches to the consideration that could be received by the holders of Navios Midstream Public Units in an effort to craft a counter-proposal that would increase the benefits received by the holders of Navios Midstream Public Units in the Proposed Transaction.

On August 28, 2018, the Navios Midstream Conflicts Committee met telephonically with Piper Jaffray and Latham to review the possible terms of a counter-proposal to be provided to Navios Acquisition. Representatives from Piper Jaffray presented a revised financial analysis for the combined company and the potential benefits to the holders of Navios Midstream Public Units if they were to receive an increased premium in the form of additional Navios Acquisition Common Stock or if they were to receive convertible preferred stock of Navios Acquisition with a liquidation preference relative to Navios Acquisition Common Stock. After discussion, the Navios Midstream Conflicts Committee approved a counter-proposal wherein the holders of Navios Midstream Public Units would receive 7.463 convertible participating preferred shares of Navios Acquisition for each Navios Midstream Common Unit. The preferred stock would participate on an as-converted basis in dividends paid to holders of Navios Acquisition Common Stock and would be entitled to a minimum annual preferred dividend of $0.066997 per share if the dividend on Navios Acquisition Common Stock for any year during the first two years after consummation of the Proposed Transaction was below that level. The preferred stock would be convertible on a one-for-one basis, subject to customary anti-dilution mechanisms, with Navios Acquisition holding an automatic conversion right after the fifth anniversary of the closing of the Proposed Transaction at a price of 150% of the implied conversion price. The Navios Acquisition convertible preferred stock would also have a liquidation preference over Navios Acquisition Common Stock and would participate pro rata with Navios Acquisition Common Stock in any liquidation value above the preference amount. On August 29, 2018, Mr. Kalafatides sent the Navios Acquisition Board a letter setting forth the terms of the counter-proposal.

During early September 2018, Mr. Kalafatides, on behalf of the Navios Midstream Conflicts Committee, held discussions regarding the counter-proposal with Ms. Frangou, as Chairman and Chief Executive Officer of

36

Navios Acquisition, and other members of Navios Acquisition management. Also during this time, Mr. Kalafatides consulted with members of the Navios Midstream Conflicts Committee and representatives from Piper Jaffray and Latham regarding various aspects of the negotiations.

During early to mid-September 2018, representatives of Fried, Frank, Harris, Shriver, and Jacobson, LLP (which we refer to as “Fried Frank”) and S. Goldman Advisors LLC (which we refer to as “S. Goldman”), on behalf of Navios Acquisition, and representatives of Latham and Piper Jaffray, on behalf of the Navios Midstream Conflicts Committee, had several telephone calls to discuss various components of the counter-proposal, including the consideration to be paid in the form of convertible preferred stock of Navios Acquisition, the liquidation preference and conversion rate applicable to the preferred stock consideration, a possible exchange ratio in respect of Navios Acquisition Common Stock that the holders of Navios Midstream Public Units could select as an alternative to the convertible preferred stock consideration and the parties’ respective valuation analyses of Navios Acquisition and Navios Midstream.

On September 19, 2018, Mr. Kalafatides and representatives of Piper Jaffray reviewed the progress of negotiations between the parties’ advisors and discussed next steps in negotiating the Proposed Transaction.

On September 20, 2018, representatives from Fried Frank and Latham and representatives from S. Goldman and Piper Jaffray met telephonically to negotiate the Proposed Transaction.

On September 21, 2018, a representative of Fried Frank communicated to representatives of Latham and Piper Jaffray possible terms for discussion in respect of the Proposed Transaction under which holders of Navios Midstream Public Units would receive, at their election, either one share of convertible preferred stock of Navios Acquisition or 6.292 shares of Navios Acquisition Common Stock for each Navios Midstream Public Unit, with each share of convertible preferred stock issued in the transaction being (i) voluntarily convertible by the holder following the six-month anniversary of the closing of the Proposed Transaction into 5 shares of Navios Acquisition Common Stock, and (ii) mandatorily convertible, at the same conversion rate, on the first to occur of (a) both the Navios Acquisition Common Stock having traded above 120% of the pre-transaction announcement trading price of the Navios Acquisition Common Stock and 12 months having elapsed, (b) 18 months having elapsed after the closing of the Proposed Transaction and (c) the number of shares of convertible preferred stock that voluntarily converted after the closing of the Proposed Transaction (plus the Navios Midstream Public Units that elected (or were deemed to have elected) consideration in the Proposed Transaction consisting of Navios Acquisition Common Stock being 66.7% of the Navios Midstream Public Units outstanding prior to closing of the Proposed Transaction). In addition, under the terms communicated for discussion, any Navios Midstream Public Units in respect of which no election was made would be deemed to have elected to receive the form of consideration most elected by the holders of Navios Midstream Public Units, and if more than 66.7% of the Navios Midstream Public Units elected (or were deemed to have elected) to receive shares of Navios Acquisition Common Stock, then all Navios Midstream Public Units would be converted into the right to receive Navios Acquisition Common Stock, and no convertible preferred stock would be issued. Furthermore, the convertible preferred stock issued in the Proposed Transaction would be entitled to the same dividends as are paid in respect of the Navios Acquisition Common Stock, on an as-converted basis, but would not be listed on any securities exchange or otherwise be publicly traded.

On September 21, 2018, Mr. Kalafatides and Ms. Frangou participated in a telephone call to discuss the possible terms for the Proposed Transaction previously communicated by the representative of Fried Frank to the representatives of Latham and Piper Jaffray.

On September 22, 2018, the Navios Midstream Conflicts Committee met telephonically with representatives of Piper Jaffray and Latham to continue to discuss the possible exchange ratio in respect of the Navios Acquisition Common Stock and the conversion ratio for the Navios Acquisition convertible preferred stock, in each case to be received by the holders of Navios Midstream Public Units upon their election of consideration in the Proposed Transaction.

37

On September 24, 2018, a representative of Piper Jaffray, after consluting with the Navios Midstream Conflicts Committee, communicated certain proposed modifications to terms initially communicated by the representative of Fried Frank, including that (i) the convertible preferred stock consideration be convertible into 5.25 (rather than 5) shares of Navios Acquisition Common Stock and mandatorily convertible, at the same conversion rate, on the first to occur of (a) both the Navios Acquisition Common Stock having traded above 120% of the pre-transaction announcement trading price of the Navios Acquisition Common Stock and three years having elapsed after the closing of the Proposed Transaction and (b) five years having elapsed after the closing of the Proposed Transaction, (ii) any Navios Midstream Public Units in respect of which no election was made would be deemed to have elected to receive the form of consideration recommended by the Navios Midstream Conflicts Committee, (iii) convertible preferred stock consideration would be available in the Proposed Transaction regardless of the percentage of Navios Midstream Public Units that elected to receive Navios Acquisition Common Stock consideration and (iv) the convertible preferred stock consideration would be listed on an exchange.

On September 24, 2018, a representative of Fried Frank responded to the representatives of Piper Jaffray and Latham with proposed terms for the Proposed Transaction under which (i) the convertible preferred stock consideration would be convertible into 5.1 shares of Navios Acquisition Common Stock and mandatorily convertible, at the same conversion rate, on the first to occur of (a) both the Navios Acquisition Common Stock having traded above 120% of the pre-transaction announcement trading price of the Navios Acquisition Common Stock and 18 months having elapsed after the closing of the Proposed Transaction, (b) two years having elapsed after the closing of the Proposed Transaction and (c) the number of shares of convertible preferred stock that voluntarily converted after the closing of the Proposed Transaction (plus the Navios Midstream Public Units that elected (or were deemed to have elected) consideration in the Proposed Transaction consisting of Navios Acquisition Common Stock) being 75% of the Navios Midstream Public Units outstanding prior to closing of the Proposed Transaction, (ii) any Navios Midstream Public Units in respect of which no election was made would be deemed to have elected to receive the form of consideration most elected by the holders of the Navios Midstream Public Units, (iii) if more than 75% of the Navios Midstream Public Units elected (or were deemed to have elected) to receive shares of Navios Acquisition Common Stock, then all Navios Midstream Public Units would be converted into the right to receive Navios Acquisition Common Stock, and no convertible preferred stock would be issued and (iv) if a majority of the outstanding Navios Midstream Public Units elect (or are deemed to have elected) to receive convertible preferred stock consideration and a listing was permitted by the NYSE, the convertible preferred stock would be listed on the NYSE.

On September 26, 2018, through a series of telephonic meetings, members of the Navios Midstream Conflicts Committee and members of the Navios Acquisition management team, on behalf of the Navios Acquisition Board, negotiated and preliminarily agreed to the terms of the consideration in the Proposed Transaction as more fully set forth in “The Merger—Description of the Merger.” Later that day, representatives of Latham, on behalf of the Navios Midstream Conflicts Committee, confirmed the preliminary agreement as to the consideration in the Proposed Transaction by email to representatives of Fried Frank.

On October 1, 2018, Fried Frank sent the initial draft of the Merger Agreement and Certificate of Designations setting forth the terms of the Navios Acquisition Series E Preferred Stock to the Navios Midstream Conflicts Committee and Latham.

Mr. Kalafatides and representatives from Latham and Piper Jaffray met telephonically on October 3, 2018 to discuss the draft transaction agreements. After discussion, Mr. Kalafatides, on behalf of the Navios Midstream Conflicts Committee, determined to propose certain changes to the Merger Agreement, including (i) inserting a termination fee of $10 million payable by Navios Acquisition to Navios Midstream in the event the Merger is not consummated due to Navios Acquisition’s breach of the Merger Agreement, (ii) proposing that Navios Midstream pay the expenses of Navios Acquisition in the event the Merger Agreement is terminated following Navios Midstream’s breach or the failure of the Merger Agreement to receive the necessary approval from the holders of Navios Midstream Units, (iii) provisions requiring that all distributions made by Navios Midstream to

38

the holders of Navios Midstream Units in the period between the signing of the Merger Agreement and closing of the Merger be in the ordinary course, consistent with past practice (including with respect to the amount and timing of record dates and payment dates) and not less than the distribution declared by the Navios Midstream Board for the quarter ended June 30, 2018, unless the Navios Midstream Conflicts Committee consents to such a change and (iv) an outside date for consummation of the Merger of six months from the date the Merger Agreement is signed by the parties. In regards to the Certificate of Designations, Mr. Kalafatides, the Navios Midstream Conflicts Committee and Latham agreed to the concept that the Navios Acquisition Series E Preferred Stock rank senior in right of liquidation to all existing and future common and preferred stock of Navios Acquisition.

Later that day, Latham sent a revised draft Merger Agreement to Fried Frank, and the firms subsequently held a telephone conference to discuss structuring the transaction so as to allow Navios Acquisition to approve the Merger Agreement via a written consent instead of through a unitholder meeting.

On October 4, 2018, Fried Frank sent revised drafts of the Merger Agreement and Certificate of Designations to Latham and the Navios Midstream Conflicts Committee. In the revised drafts, Navios Acquisition responded to the Navios Midstream Conflicts Committee’s request for the Navios Acquisition Series E Preferred Stock to be senior in rank and liquidation preference to all existing and future Navios Acquisition preferred stock by proposing that the Navios Acquisition Series E Preferred Stock be senior only to all existing Navios Acquisition preferred stock (as well as Navios Acquisition Common Stock). Navios Acquisition also proposed a five-day volume-weighted average price as the basis for the liquidation preference and automatic conversion trigger price of Navios Acquisition Common Stock, instead of the previously discussed 20-day period. The revised draft of the Merger Agreement also eliminated the $10 million termination fee proposed by Navios Midstream and provided for a reciprocal reimbursement of expenses, capped at $1 million in the event that the Merger Agreement was terminated because of a breach by the other party.

Also on October 4, 2018, representatives of Latham’s tax team discussed tax-related representations and warranties, covenants and conditions to closing with representatives of Fried Frank’s tax team. The parties discussed whether to provide that the receipt of Fried Frank’s opinion as to the tax-free nature of the transaction would be a condition to Navios Midstream’s obligation to consummate the Merger.

On October 5, 2018, Mr. Kalafatides, Latham and Piper Jaffray met telephonically to discuss Navios Acquisition’s revised draft of the Merger Agreement, in which, among other things, Navios Acquisition had agreed to covenant to provide a written consent to approve the Merger rather than providing its vote in favor of the Merger at a Navios Midstream Unitholder meeting. The participants discussed the fact that Navios Acquisition had removed all references to disclosure schedules, indicating that the representations and warranties of Navios Acquisition as drafted in the agreement were accurate. The participants also discussed whether it would be appropriate to seek to restrict Navios Acquisition’s ability to issue debt and equity securities in the time period between signing the Merger Agreement and consummating the Merger as a means of preserving the value to be received by holders of Navios Midstream Public Units as Merger Consideration. Mr. Kalafatides, Piper Jaffray and Latham also discussed the Navios Midstream Conflicts Committee’s desire to preserve the level of distributions to be received by holders of Navios Midstream Public Units for the quarter ended September 30, 2018 and for future quarters, if possible. Because Navios Acquisition controlled the majority of the Navios Midstream Board, the Navios Midstream Conflicts Committee sought protections for such distributions in the Merger Agreement. The Navios Midstream Conflicts Committee decided that, in light of the expected timeframe between signing and closing, it would be appropriate to provide only that the distribution for the quarter ended September 30, 2018 would not be less than the distribution declared for the quarter ended June 30, 2018. Mr. Kalafatides also determined to accept the reciprocal expense reimbursement provision not to exceed $1 million in the event the transaction were to fail to be consummated as a result of the other party having breached the Merger Agreement. After discussing these provisions, Mr. Kalafatides instructed Latham to send a revised draft Merger Agreement and Certificate of Designations to Navios Acquisition and Fried Frank.

On October 6, 2018, Fried Frank circulated a revised draft of the Merger Agreement to Latham. Later that day, the Navios Midstream Conflicts Committee, Latham and Piper Jaffray reviewed and corresponded with one another regarding the revised Merger Agreement terms sent by Fried Frank, including the flexibility for Navios Acquisition to (i) issue up to $50 million in equity, (ii) issue debt to refinance existing indebtedness, (iii) issue intracompany debt and (iv) issue debt up to an aggregate of 10% in principal amount of the aggregate principal amount of debt outstanding as of October 7, 2018, in each case during the period between signing of the Merger Agreement and the consummation of the Merger. In addition, the revised terms proposed on behalf of Navios Acquisition provided that Fried Frank’s tax opinion would not be a condition to Navios Midstream’s obligation to consummate the Merger. After discussion, the Navios Midstream Conflicts Committee agreed that these were acceptable provisions to provide Navios Acquisition with the flexibility to pursue strategic opportunities that may arise in the period between signing the Merger Agreement and the consummation of the Merger. Mr. Kalafatides instructed Latham to finalize the Merger Agreement with Fried Frank.

On October 7, 2018, the Navios Acquisition Board met, with representatives of S. Goldman and Fried Frank present, to discuss the terms of the Merger Agreement and Certificate of Designation. Representatives of Fried Frank summarized the terms of the Merger Agreement and Certificate of Designations and discussed the Merger. The Navios Acquisition Board discussed the foregoing matters and following such discussions, upon a motion duly presented by Ms. Frangou, unanimously voted to (i) approve the Merger Agreement and the transactions contemplated thereby, including the Merger and (ii) authorize Navios Acquisition to enter into the Merger Agreement and consummate the Merger upon the terms and conditions set forth in the Merger Agreement.

On October 7, 2018, the Navios Midstream Conflicts Committee met, with representatives from Latham and Piper Jaffray present, to discuss the terms of the Merger Agreement and Certificate of Designations. Representatives from Latham reviewed with the Navios Midstream Conflicts Committee their responsibilities under the Fifth Amended and Restated Limited Partnership Agreement and the Marshall Islands Business Corporations Act (which we refer to as the “MIBCA”) in connection with reviewing and determining whether to approve the Merger, and summarized the terms of the Merger Agreement and Certificate of Designations. Representatives from Piper Jaffray then reviewed their financial analysis of the Merger and orally presented their opinion that, as of October 7, 2018, the Preferred Stock Consideration is fair to Navios Midstream and to the holders of Navios Midstream Public Units, from a financial point of view. After discussing the presented materials, the Navios Midstream Conflicts Committee, upon a motion duly presented by Mr. Kalafatides, unanimously voted to (i) approve the Merger Agreement and the transactions contemplated thereby, including the Merger and (ii) recommend that the Navios Midstream Board (a) approve the Merger Agreement and the transactions contemplated thereby, including the Merger, (b) submit the Merger Agreement to the limited partners of Navios Midstream for approval, (c) recommend that the limited partners of Navios Midstream approve the Merger Agreement and the Merger upon the terms and conditions set forth in the Merger Agreement and (d) cause Navios Midstream to enter into the Merger Agreement and, subject to obtaining the requisite approval of the limited partners of Navios Midstream, consummate the Merger upon the terms and conditions set forth in the Merger Agreement, with such approval and recommendation constituting Special Approval (as defined below in the section titled “The Merger — Resolution of Conflicts of Interest; Standards of Conduct and Modification of Duties”) of the Merger on the terms set forth in the Merger Agreement.

On October 7, 2018, following the meeting of the Navios Midstream Conflicts Committee, the Navios Midstream Board met, with representatives from Thompson Hine LLP (“Thompson Hine”), as corporate counsel to Navios Midstream, and Latham present, to discuss the terms of the Merger Agreement and Certificate of Designations and the recommendation of the Navios Midstream Conflicts Committee. Representatives from Thompson Hine reviewed the overall terms of the Transaction with the Navios Midstream Board and representatives from Latham summarized the terms of the Merger Agreement and Certificate of Designations and reviewed the recommendation of the Navios Midstream Conflicts Committee. After discussing matters referenced above, the Navios Midstream Board, upon a motion duly presented by Ms. Frangou, unanimously voted to (i) approve the Merger Agreement and the transactions contemplated thereby, including the Merger, (ii) submit the Merger Agreement to the limited partners of Navios Midstream for approval by written consent

40

and (iii) authorize Navios Midstream to enter into the Merger Agreement and, subject to obtaining the requisite approval of the limited partners of Navios Midstream, consummate the Merger upon the terms and conditions set forth in the Merger Agreement.

On October 8, 2018, Navios Acquisition and Navios Midstream issued a press release announcing the Merger.

Resolution of Conflict of Interest; Standards of Conduct and Modification of Duties

The approval of the Merger Agreement and the transactions contemplated thereby, including the Merger, by the Navios Midstream Conflicts Committee, acting in good faith, constitutes special approval of the Conflicts Committee (which we refer to as “Special Approval”) under the Fifth Amended and Restated Agreement of Limited Partnership.

Under Section 7.17(a) of the Fifth Amended and Restated Limited Partnership Agreement, whenever a potential conflict of interest exists, such as the Merger and the other transactions contemplated by the Merger Agreement, any resolution or course of action by the Navios Midstream Board in respect of such conflict of interest will be permitted and deemed approved by all of the partners of Navios Midstream and will not constitute a breach of the Fifth Amended and Restated Limited Partnership Agreement or of any duty stated or implied by law, in equity or otherwise, if the resolution or course of action is approved by Special Approval. In order for a determination or other action by the Navios Midstream Conflicts Committee to be in “good faith” under the Fifth Amended and Restated Limited Partnership Agreement, the persons making such determination or taking or declining to take such other action must reasonably believe that the determination or other action is in the best interests of Navios Midstream.

Further, under Section 7.18(b) of the Fifth Amended and Restated Limited Partnership Agreement, any action taken or omitted to be taken by the Navios Midstream Board in reliance upon the advice or opinion of an investment banker, counsel, and others, as to matters reasonably believed to be in such person’s professional or expert competence will be “conclusively presumed to have been done or omitted in good faith and in accordance with such advice or opinion.”

Recommendation of the Navios Midstream Conflicts Committee

In connection with the initial public offering of Navios Midstream, the Navios Midstream Board established and authorized the Navios Midstream Conflicts Committee, consisting of Alex Kalafatides, Christos Kokkinis and Vasilios Mouyis, each of whom the Navios Midstream Board determined satisfied the independence and other requirements set forth in Navios Midstream’s Fifth Amended and Restated Limited Partnership Agreement, to resolve certain conflicts of interest that may exist between the interests of Navios Midstream GP and its controlling affiliates, including Navios Acquisition, on the one hand, and the interests of Navios Midstream and the holders of Navios Midstream Public Units, on the other hand.

In light of a potential conflict of interest in connection with the Merger, the Navios Midstream Conflicts Committee determined to, among other things, (i) review, evaluate and negotiate the Merger and related arrangements and agreements with Navios Acquisition on behalf of Navios Midstream and the holders of Navios Midstream Public Units, (ii) make a recommendation to the Navios Midstream Board whether to approve the Merger and related arrangements and agreements and (iii) decide whether to approve the Merger and related arrangements and agreements by Special Approval.

The Navios Midstream Conflicts Committee, with the assistance of its advisors, reviewed, negotiated and evaluated the Merger Agreement and the transactions contemplated thereby, including the Merger, and certain related arrangements and agreements. Following that process, the Navios Midstream Conflicts Committee, by unanimous vote at a meeting held on October 7, 2018, (i) determined in good faith that the Merger Agreement

41

and the transactions contemplated thereby, including the Merger, are in the best interests of Navios Midstream and the holders of Navios Midstream Public Units, (ii) approved the Merger Agreement and the transactions contemplated thereby, including the Merger and (iii) recommended that the Navios Midstream Board (a) approve the Merger Agreement and the transactions contemplated thereby, including the Merger, (b) submit the Merger Agreement to the limited partners of Navios Midstream for approval, (c) recommend that the limited partners of Navios Midstream approve the Merger Agreement and the Merger upon the terms and conditions set forth in the Merger Agreement and (d) cause Navios Midstream to enter into the Merger Agreement and consummate the Merger upon the terms and conditions set forth in the Merger Agreement, subject to obtaining the requisite approval of the limited partners of Navios Midstream. The Navios Midstream Conflicts Committee’s approval of the Merger Agreement and the transactions contemplated thereby, including the Merger, constitutes Special Approval under the Fifth Amended and Restated Limited Partnership Agreement.

Based on the Navios Midstream Conflicts Committee’s recommendation, the Navios Midstream Board, at a meeting held on October  7, 2018, unanimously approved the Merger Agreement and the transactions contemplated thereby, including the Merger.

Reasons for the Navios Midstream Conflicts Committee’s Recommendation

The Navios Midstream Conflicts Committee considered many factors in making its determination, providing Special Approval and making its recommendation. The Navios Midstream Conflicts Committee consulted with its financial and legal advisors and viewed the following factors as being generally positive or favorable in coming to its determination, decision to provide Special Approval and related recommendation:

42

43

The Navios Midstream Conflicts Committee considered the following factors to be generally negative or unfavorable in making its determination that the Merger Agreement and the transactions contemplated thereby, including the Merger, are in the best interests of Navios Midstream and the holders of Navios Midstream Public Units:

44

The foregoing discussion is not intended to be exhaustive, but is intended to address the material information and principal factors considered by the Navios Midstream Conflicts Committee in considering the

45

Merger. In view of the number and variety of factors and the amount of information considered, the Navios Midstream Conflicts Committee did not find it practicable to, and did not make specific assessments of, quantify or otherwise assign relative weights to, the specific factors considered in reaching its determination. In addition, the Navios Midstream Conflicts Committee did not undertake to make any specific determination as to whether any particular factor, or any aspect of any particular factor, was favorable or unfavorable to its ultimate determination and individual members of the Navios Midstream Conflicts Committee may have given different weights to different factors. The Navios Midstream Conflicts Committee made its determination, approval and recommendation based on the totality of information presented to, and the investigation conducted by, the Navios Midstream Conflicts Committee. It should be noted that certain statements and other information presented in this section are forward-looking in nature and, therefore, should be read in light of the factors discussed under the heading “Cautionary Statement Regarding Forward-Looking Statements.”

Unaudited Financial Projections of Navios Acquisition and Navios Midstream

In connection with the proposed Merger, management of Navios Midstream provided internal non-public projections relating to Navios Midstream, and management of Navios Acquisition provided internal non-public projections relating to Navios Acquisition, in each case to the Navios Midstream Conflicts Committee and its financial advisor Piper Jaffray for their use in negotiating the terms of the Merger with Navios Acquisition and for use by Piper Jaffray in connection with its performance of its financial analysis and delivery of its opinion to the Navios Midstream Conflicts Committee. The projections for Navios Midstream were prepared on a stand-alone basis and the projections for Navios Acquisition reflected Navios Acquisition’s pre-Merger ownership position in Navios Midstream. A summary of these projections, rounded to the nearest hundred million, is included below to give holders of Navios Midstream Public Units access to certain non-public unaudited prospective financial information that was made available to Piper Jaffray, the Navios Midstream Conflicts Committee and the Navios Midstream Board in connection with the Merger.

You should be aware that uncertainties are inherent in prospective financial information of any kind. Neither Navios Acquisition, Navios Midstream nor any of their respective affiliates, advisors, officers, directors or representatives have made or make any representation or can give any assurance to any holder of Navios Midstream Common Units or any other person regarding the ultimate performance of Navios Midstream or Navios Acquisition compared to the summarized information set forth below or that any such results will be achieved.

The inclusion of the following summary projections in this information statement/prospectus should not be regarded as an indication that Navios Acquisition, Navios Midstream or their respective representatives considered or consider the projections to be a reliable or accurate prediction of future performance or events, and the summary projections set forth below should not be relied upon as such.

The Navios Midstream and Navios Acquisition projections were not prepared with a view toward public disclosure or toward compliance with GAAP, the published guidelines of the SEC, or the guidelines established by the American Institute of Certified Public Accountants. Neither PricewaterhouseCoopers S.A (which we refer to as “PwC”), Ernst & Young (Hellas) Certified Auditors Accountants S.A. (which we refer to as “EY”), nor any other independent registered public accounting firm has compiled, examined or performed any procedures with respect to the prospective financial information contained in the projections and accordingly, neither PwC nor EY expresses an opinion or any other form of assurance with respect thereto. The PwC reports included in Navios Acquisition’s Annual Report on Form 20-F for the fiscal year ended December 31, 2017 and attached as Annex D to this information statement/prospectus relate to solely historical financial information of Navios Acquisition, and the EY reports included in Navios Midstream’s Annual Report on Form 20-F for the fiscal year ended December 31, 2017 and attached as Annex F to this information statement/prospectus relate to historical financial information of Navios Midstream. Such reports do not extend to the projections included below and should not be read to do so. Neither the Navios Acquisition Board, Navios Midstream Board nor the Navios Midstream Conflicts Committee prepared the summarized information and neither the Navios Acquisition Board,

46

the Navios Midstream Board, the Navios Midstream Conflicts Committee, Navios Acquisition nor Navios Midstream gives any assurance regarding the summarized information. The internal financial projections of Navios Midstream and Navios Acquisition are inherently subjective in nature, susceptible to interpretation and, accordingly, such forecasts may not be achieved.

The projections summarized below reflect numerous assumptions made by management of Navios Acquisition and Navios Midstream, including material assumptions that may not be realized and are subject to significant uncertainties and contingencies, all of which are difficult to predict and many of which are beyond the control of the preparing party. Accordingly, there can be no assurance that the assumptions made in preparing the projections will prove accurate. There will be differences between actual and forecasted results, and the differences may be material. The risk that these uncertainties and contingencies could cause the assumptions to fail to be reflective of actual results is further increased due to the length of time in the future over which these assumptions apply. Any inaccuracy of assumptions and projections in early periods could have a compounding effect on the projections shown for the later periods. Thus, any failure of an assumption or projection to be reflective of actual results in an early period could have a greater effect on the projected results failing to be reflective of actual events in later periods. The projections presented are forward-looking in nature, subject to risks and uncertainties and, therefore, should be read in light of the factors discussed under the heading “Cautionary Note Regarding Forward-Looking Statements.”

Some of the above measures are not measures of financial performance under GAAP, and should not be considered as alternatives to net income (loss), operating income, or other performance measures derived in accordance with GAAP. Navios Acquisition’s computations of these measures may differ from similarly titled measures used by others.

NEITHER NAVIOS MIDSTREAM NOR NAVIOS ACQUISITION INTEND TO UPDATE OR OTHERWISE REVISE THE ABOVE PROSPECTIVE FINANCIAL INFORMATION TO REFLECT CIRCUMSTANCES EXISTING AFTER THE DATE SUCH PROSPECTIVE FINANCIAL INFORMATION WAS PREPARED OR TO REFLECT THE OCCURRENCE OF SUBSEQUENT EVENTS, EVEN IN THE EVENT THAT ANY OR ALL OF THE ASSUMPTIONS UNDERLYING SUCH PROSPECTIVE FINANCIAL INFORMATION ARE NO LONGER APPROPRIATE.

Opinion of Financial Advisor to Navios Midstream’s Conflicts Committee

On October 7, 2018, Piper Jaffray, financial advisor to the Navios Midstream Conflicts Committee, delivered its oral opinion to the Navios Midstream Conflicts Committee, which opinion was subsequently confirmed by delivery of a written opinion dated October 7, 2018, to the effect that, as of such date and based upon and subject to the various assumptions, qualifications and limitations set forth in Piper Jaffray’s opinion, the Preferred Stock Consideration to be paid by Navios Acquisition in connection with the transaction contemplated pursuant to the terms of the Merger Agreement was fair, from a financial point of view, to Navios Midstream and to the holders of Navios Midstream’s Public Units.

The full text of the written opinion of Piper Jaffray sets forth, among other things, the procedures followed, assumptions made, matters considered and qualifications and limitations on the scope of review

47

undertaken by Piper Jaffray in rendering its opinion, and is attached hereto as Annex C. You are encouraged to read Piper Jaffray’s opinion carefully and in its entirety.

Piper Jaffray’s opinion was prepared at the request, and provided for the information, of the members of the Navios Midstream Conflicts Committee (solely in their capacity as such), in connection with their evaluation of the Merger and addresses only the fairness, from a financial point of view, to Navios Midstream and the holders of Navios Midstream Common Units (other than Navios Acquisition and its affiliates) of the Preferred Stock Consideration contemplated by the Merger Agreement and does not address any other term or agreement relating to the Merger. Piper Jaffray was not requested to opine as to, and this opinion does not address, the Common Stock Consideration, the mechanics of the Election, the basic business decision to proceed with or effect the Merger, the merits of the Merger relative to any alternative transaction or business strategy that may be available to Navios Midstream, the probability of closing any or all of the transactions contemplated by the Merger Agreement, the relative fairness of the Common Stock Consideration as compared to the Preferred Stock Consideration, the allocation of the Preferred Stock Consideration or Common Stock Consideration among the holders of Navios Midstream Common Units based on the Election or the transaction structure, or the fairness of the terms of the transaction to any creditor or other constituency of Navios Midstream. In addition, this opinion does not address in any manner the prices at which the Preferred Stock or Common Stock will trade following announcement or consummation of the Merger or at any time and Piper Jaffray expresses no opinion or recommendation whether the holders of Navios Midstream Public Units should elect the Preferred Stock Consideration or Common Stock Consideration. In rendering this opinion, Piper Jaffray has assumed that all holders of Navios Midstream Common Units elect the Preferred Stock Consideration and no shares of Navios Acquisition Common Stock are issued in the Merger, and expresses no opinion as to the fairness of the Common Stock Consideration to any holder of Navios Midstream Common Units. The summary of the Piper Jaffray opinion set forth herein is qualified in its entirety by reference to the full text of the opinion attached hereto as Annex C.

In conducting its investigation and analyses and in arriving at its opinion, Piper Jaffray reviewed such information and took into account such financial and economic factors, investment banking procedures and considerations as it deemed relevant under the circumstances. Subject to the various assumptions, qualifications and limitations set forth in its opinion, Piper Jaffray has reviewed and analyzed, among other things, the following:

48

In arriving at its opinion, Piper Jaffray assumed and relied upon, without independent verification, the accuracy and completeness of all of the financial and other information that was publicly available or provided to Piper Jaffray by or on behalf of Navios Midstream or Navios Acquisition. Piper Jaffray was not engaged to verify, and has not, independently verified any information provided to it by or on behalf of Navios Midstream or Navios Acquisition (including the information that formed a substantial basis for Piper Jaffray’s opinion), has not assumed any responsibility to verify, assumes no liability for, and expresses no opinion on, any such information, and Piper Jaffray has assumed, without independent verification, that neither Navios Midstream nor Navios Acquisition is aware of any information prepared by it or its advisors that might be material to Piper Jaffray’s opinion that has not been provided to Piper Jaffray. Piper Jaffray assumed, without any independent verification, that (i) all material assets and liabilities (contingent or otherwise, known or unknown) of Navios Midstream and Navios Acquisition are as set forth in their respective financial statements or as otherwise provided to Piper Jaffray, (ii) the financial statements of Navios Midstream and Navios Acquisition provided to Piper Jaffray present fairly the results of operations, cash flows and financial condition of Navios Midstream and Navios Acquisition for the periods, and as of the dates, indicated and were prepared in conformity with U.S. generally accepted accounting principles consistently applied, except as Piper Jaffray has otherwise been informed, (iii) the forecasts for Navios Midstream and Navios Acquisition were reasonably prepared on bases reflecting the best available estimates and good faith judgments of Navios Midstream’s and Navios Acquisition’s senior management as to the future performance of Navios Midstream and Navios Acquisition, and Piper Jaffray has relied, without independent verification, upon such forecasts in the preparation of its opinion, although Piper Jaffray expresses no opinion with respect to the forecasts or any judgments, estimates, assumptions or basis on which they were based, and Piper Jaffray assumed, without independent verification, that the forecasts provided by Navios Midstream’s and Navios Acquisition’s management will be realized in the amounts and on the time schedule contemplated, (iv) the Merger will be consummated in accordance with the terms and conditions of the Merger Agreement without any amendment and without waiver by any party of any of the conditions to their obligations thereunder, (v) the representations and warranties contained in the Merger Agreement are true and correct and that each party will perform all of the covenants and agreements required to be performed by it under the Merger Agreement, (vi) all corporate, governmental, regulatory or other consents and approvals (contractual or otherwise) required to consummate the Merger have been, or will be, obtained without the need for any divestitures or other changes to the Preferred Stock Consideration, or other financial terms of the Merger or that

49

would otherwise materially affect Navios Midstream or Navios Acquisition, or Piper Jaffray’s analysis, (vii) all holders of Navios Midstream Common Units elect the Preferred Stock Consideration and no shares of Common Stock are issued in the Merger and (viii) any post-closing adjustments contemplated by the Merger Agreement will not affect the Preferred Stock Consideration, or Piper Jaffray’s analysis of the Merger.

Piper Jaffray does not provide accounting, tax or legal advice and therefore has not expressed an opinion on such matters as they relate to the Merger. In conducting its review, Piper Jaffray has not undertaken or obtained an independent evaluation or appraisal of any of the assets or liabilities (contingent or otherwise, known or unknown) or solvency of Navios Midstream or Navios Acquisition nor has Piper Jaffray made a physical inspection of the properties or facilities of Navios Midstream or Navios Acquisition. Piper Jaffray has not considered any potential adjustments, other than those contemplated by the Merger Agreement, to the Preferred Stock Consideration, as part of its analysis. In each case, Piper Jaffray has made the assumptions and taken the actions or inactions described in the opinion with the knowledge and consent of the Navios Midstream Conflicts Committee.

Piper Jaffray’s opinion necessarily was based upon economic, monetary and market conditions as they existed and could be evaluated on the date of the opinion, and does not predict or take into account any changes which may occur, or information which may become available, after that date. Furthermore, Piper Jaffray expressed no opinion as to the price or trading range at which any of Navios Midstream’s and Navios Acquisition’s securities (including Navios Midstream Common Units and Navios Acquisition Common Stock) will trade following the date of the opinion or as to the effect of the Merger on such price or trading range, or any earnings or ownership dilutive impact, if any, that may result from the issuance of Navios Acquisition Common Stock upon conversion of the Preferred Stock Consideration. Such price and trading range may be affected by a number of factors, including but not limited to (i) dispositions of Navios Midstream Common Units and Navios Acquisition Common Stock by stockholders and unitholders within a short period of time after, or other market effects resulting from, the announcement and/or effective date of the Merger, (ii) changes in prevailing interest rates and other factors which generally influence the price of securities, (iii) adverse changes in the current capital markets, (iv) the occurrence of adverse changes in the financial condition, business, assets, results of operations or prospects of Navios Midstream or Navios Acquisition or in Navios Midstream’s or Navios Acquisition’s industries, (v) adverse changes in oil, natural gas, natural gas liquids or other commodity prices, (vi) any necessary actions by, or restrictions of, federal, state or other governmental agencies or regulatory authorities and (vii) timely completion of the Merger on terms and conditions that are acceptable to each party.

Piper Jaffray’s opinion was only one of many factors considered by the Navios Midstream Conflicts Committee in its evaluation of the Merger and should not be viewed as determinative of the views of the members of the Navios Midstream Conflicts Committee with respect to the Merger, the Preferred Stock Consideration or the Common Stock Consideration. Set forth below is a summary of the material financial analyses reviewed by Piper Jaffray with the Navios Midstream Conflicts Committee on October 7, 2018, in connection with the rendering of its opinion. The following summary, however, does not purport to be a complete description of the analyses performed by Piper Jaffray. The order of the analyses described and the results of these analyses do not represent the relative importance or weight given to these analyses by Piper Jaffray. Except as otherwise noted, the following quantitative information, to the extent that it is based on market data, is based on market data that existed on or before October 7, 2018, and is not necessarily indicative of subsequent or current market conditions.

Merger Analysis

To evaluate the Merger and the Preferred Stock Consideration, Piper Jaffray performed certain financial analyses to derive an implied per unit range of values for Navios Midstream Common Units, including but not limited to (i) a discounted cash flow analysis, (ii) comparable partnership trading analysis, (iii) a selected comparable maritime precedent transactions analysis, (iv) a selected comparable premiums paid analysis and (iv) a precedent preferred transaction analysis. Piper Jaffray performed its analysis utilizing the financial projections for Navios Midstream provided by Navios Midstream management (a) based on the base case, which

50

are referred to in this section as “Navios Midstream Forecast — Base Case” and (b) based on the sensitivity case, which are referred to in this section as “Navios Midstream Forecast — Sensitivity Case.” The Navios Midstream Forecast — Base Case and the Navios Midstream Forecast — Sensitivity Case are collectively referred to in this section as the “Navios Midstream Forecasts.”

After conversations with Navios Midstream management, the Navios Midstream Forecast — Base Case was adjusted by Piper Jaffray by reducing the unsecured charter rates and the number of days of operation for each vessel with unsecured charters to create the Navios Midstream Forecast — Sensitivity Case.

Piper Jaffray also performed certain financial analyses to derive an implied per unit range of values for Navios Acquisition Common Stock, including but not limited to (i) a discounted cash flow analysis, (ii) a comparable company trading analysis and (iii) a selected comparable maritime precedent transactions analysis. Piper Jaffray performed its analysis utilizing the financial projections for Navios Acquisition provided by Navios Acquisition management (a) based on the base case, which are referred to in this section as “Navios Acquisition Forecast — Base Case” and (b) based on the sensitivity case, which are referred to in this section as “Navios Acquisition Forecast — Sensitivity Case.” The Navios Acquisition Forecast — Base Case and the Navios Acquisition Forecast — Sensitivity Case are collectively referred to in this section as the “Navios Acquisition Forecasts.”

After conversations with Navios Acquisition management, the Navios Acquisition Forecast — Base Case was adjusted by Piper Jaffray by reducing the unsecured charter rates and the number of days of operation for each vessel with unsecured charters to create the Navios Acquisition Forecast — Sensitivity Case.

Analysis of Navios Midstream

Discounted Cash Flow Analysis

Piper Jaffray performed an indicative discounted cash flow analysis of Navios Midstream based on the implied present value of Navios Midstream’s estimated future net cash flows. Piper Jaffray calculated Navios Midstream’s estimated future net cash flows based on the Navios Midstream Forecasts.

Piper Jaffray calculated the implied per unit value range for the Navios Midstream Common Units by utilizing a range of discount rates with a mid-point based on Navios Midstream’s Long Term Cost of Capital, as estimated by Piper Jaffray based on Navios Midstream’s current yield, projected long-term cost of debt and long-term distribution growth rates, Navios Midstream’s projected unlevered free cash flows for calendar year 2018 through calendar year 2022 and terminal values as of December 31, 2022 based on a range of EBITDA exit multiples. Piper Jaffray assumed a range of discount rates from 9.5% to 15.5% and a range of earnings before interest, taxes, depreciation and amortization (which we refer to as “EBITDA”) terminal multiples from 4.0x to 6.0x.

The discounted cash flow analysis based on the implied present value of cash flows in the Navios Midstream Forecasts indicated a value range of $0.00 to $3.50 per Navios Midstream Common Unit

Comparable Partnership Trading Analysis

In order to assess how the public market values equity units of similar publicly traded diversified Master Limited Partnerships (which we refer to as “MLPs”), Piper Jaffray reviewed and compared specific financial data relating to Navios Midstream to that of a group of selected MLPs that Piper Jaffray deemed to have similar business and industry characteristics as Navios Midstream. The publicly traded MLPs that Piper Jaffray deemed to have similar characteristics to those of Navios Midstream for the purposes of its analysis were the following:

51

None of the selected publicly traded MLPs are identical or directly comparable to Navios Midstream. No specific numeric or other similar criteria were used to select the MLPs and all criteria were evaluated in their entirety without application of definitive qualifications or limitations to individual criteria.

As part of its analysis, Piper Jaffray calculated and analyzed (i) the ratios of enterprise value (which we refer to as “EV”) to estimated 2019 and 2020 EBITDA for the selected publicly traded MLPs and (ii) the ratios of the EV to estimated 2019 and 2020 EBITDA for Navios Midstream. Piper Jaffray calculated all multiples based on closing unit prices as of September 25, 2018 for each respective MLP. Piper Jaffray utilized EBITDA multiples, instead of alternative valuation metrics, as it believes that the EBITDA multiple is the most relevant valuation metric when analyzing Navios Midstream’s peers to determine the value of the Navios Midstream Common Units in this circumstance.

The financial data for the selected publicly traded MLPs were based on publicly available filings and financial projections provided by Wall Street equity research. Navios Midstream’s projected financial metrics for 2019 and 2020 were set forth in the Navios Midstream Forecasts.

The low, median and high EV to estimated 2019 EBITDA multiples of the comparable MLPs were 5.2x, 6.1x and 9.0x, respectively. The low, mean, median and high EV to estimated 2020 EBITDA multiples of the comparable MLPs were 4.0x, 5.8x and 7.3x, respectively.

Piper Jaffray then applied this range of multiples to estimated 2019 and 2020 EBITDA for Navios Midstream in accordance with the Navios Midstream Forecasts and averaged the results for 2019 and 2020. This analysis indicated a value range of $3.00 to $11.00 per Navios Midstream Common Unit.

Selected Comparable Precedent Transactions Analysis

Piper Jaffray reviewed and compared implied data for the following selected transactions involving target companies or partnerships that Piper Jaffray deemed to have similar business and industry characteristics as Navios Midstream to derive an implied range of values for the Navios Midstream Common Units. Piper Jaffray selected and reviewed data for the following selected transactions, which occurred since October 2014:

None of the selected transactions or the selected companies or partnerships that were involved in the selected transactions were directly comparable to the Merger or Navios Midstream. An analysis of the results, therefore, requires complex considerations and judgments regarding the financial and operating characteristics of Navios Midstream and the companies or partnerships involved in the comparable precedent transactions analysis, as well as other facts that could affect their transaction values.

Multiples for the selected transactions were based on publicly available information. Piper Jaffray utilized EBITDA multiples, instead of alternative valuation metrics, as it believes that the EBITDA multiple is the most

52

relevant valuation metric when analyzing precedent transactions to determine the value of Navios Midstream in this circumstance.

Piper Jaffray reviewed the historical EBITDA multiples paid in the selected transactions and derived low, median and high multiples of EV to EBITDA of 2.0x, 6.8x and 19.2x, respectively. Piper Jaffray then applied this range of selected multiples to estimated 2019 EBITDA for Navios Midstream in accordance with the Navios Midstream Forecasts and calculated the implied equity value per Navios Midstream Common Unit which indicated a value range of $6.25 to $14.00 per Navios Midstream Common Unit.

Premiums Paid Analysis
