July 31, 2012 — Covington, Louisiana — Hornbeck Offshore Services, Inc. (NYSE: HOS) announced today the commencement, on Monday, July 30, 2012, of its offer to exchange any and all of the $375,000,000 aggregate principal amount of its outstanding 5.875% Series A Senior Notes due 2020 (CUSIPs 440543 AJ 5 and U44070 AD 9) (collectively, the “Old Notes”), which were issued in a private placement and sold in accordance with Rule 144A or Regulation S under the Securities Act of 1933 (the “Act”), for an equal aggregate principal amount of its 5.875% Series B Senior Notes due 2020 (CUSIP 440543 AL 0) (the “New Notes”). The issuance of the New Notes has been registered under the Act.
