Horizon Lines, Inc.

Horizon Lines, Inc. (“Horizon,” the “Company,” “we,” “our” or “us”) is filing this Amendment No. 1 on Form 10-K/A (this “Amendment”) to amend the Company’s Annual Report on Form 10-K for the fiscal year ended December 21, 2014 (the “2014 10-K”), originally filed with the Securities and Exchange Commission (the “SEC”) on March 13, 2015, to amend the cover page to list the Company’s common stock under the caption entitled “Securities registered pursuant to Section 12(g) of the Act” and remove the Company’s common stock from the caption entitled “Securities registered pursuant to Section 12(b) of the Act.”

Except as described above, no other changes have been made to the 2014 10-K, and this Form 10-K/A does not modify, amend or update in any way any of the financial or other information contained in the 2014 10-K. This Amendment does not reflect events occurring after the date of the filing of our 2014 10-K, nor does it amend, modify or otherwise update any other information in our 2014 10-K. Accordingly, this Amendment should be read in conjunction with our 2014 10-K and with our filings with the SEC subsequent to the filing of our 2014 10-K.

Pursuant to Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), this Form 10-K/A also contains certifications pursuant to Section 302 of the Sarbanes-Oxley Act of 2002, which are attached hereto. Because no financial statements have been included in this Form 10-K/A and this Form 10-K/A does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4, and 5 of the certifications have been omitted. Terms used but not defined herein are as defined in our 2014 10-K.

Pursuant to the requirements of Section 13 or 15(d) of the Exchange Act, the Registrant has duly caused this report to be signed on its behalf by the undersigned, thereunto duly authorized on the 26th day of May, 2015.
