A copy of the amendment is attached as Exhibit 1.1 to this Report and is incorporated herein by reference.

The reverse stock split became effective at 12:01 a.m. New York City time on November 14, 2018 (the “Effective Date”), and the Company’s common stock began trading on a post-split basis on the New York Stock Exchange on the Effective Date, under its existing trading symbol “NNA.” The new CUSIP number for the Company’s common stock following the reverse stock split is Y62159 143.

Upon effectiveness of the reverse stock split, every 15 shares of the Company’s issued and outstanding pre-reverse split common stock were combined and reclassified into one share of the Company’s common stock. As of the date hereof, approximately 9,525,776 shares of common stock are issued and outstanding on a post-split basis.

The number of authorized shares and other terms of the Company’s common stock were not affected by the reverse stock split. The Company’s transfer agent, Continental Stock Transfer & Trust Company, is acting as its exchange agent and will send instructions to stockholders of record holding shares in certificate form regarding the exchange of such certificates for a new certificate representing the shares of common stock resulting from the reverse stock split.
