Hornbeck Offshore Services ^{Filed, US Offering, NYSE: HOS}

Hornbeck is a leading provider of marine transportation services to customers in the offshore oilfield market and diversified non-oilfield markets, including military support services, renewable energy development and other non-oilfield service offerings. Since our founding more than 26 years ago, we have focused on providing innovative, technologically advanced marine solutions to meet the evolving needs of our customers across our core geographic regions covering the United States and Latin America. Our team brings substantial industry expertise built through decades of experience and has leveraged that knowledge to amass what we believe is one of the largest, highest specification fleets of Offshore Supply Vessels (“OSVs”) and Multi-Purpose Support Vessels (“MPSVs”) in the industry. Approximately 75% of our total fleet consists of high-spec or ultra high-spec vessels, and we believe we have the number one ultra high-spec market position in the U.S., and the third largest fleet of high-spec and ultra high-spec OSVs in the world, measured by DWT capacity. We own a fleet of 75 multi-class OSVs and MPSVs, 58 of which are U.S. Jones Act-qualified vessels. Our Jones Act-qualified high-spec and ultra high-spec OSVs account for approximately 26% of the total industry supply of such vessels.
