Horizon Lines' Stock to Trade on the OTC Market With New Trading Symbol 'HRZL' Starting October 20, 2011

Horizon Lines HRZ today announced that its common stock will begin trading on the OTCQB Marketplace, effective October 20, 2011, under the ticker symbol "HRZL". The transition to the OTCQB Marketplace comes after the New York Stock Exchange announced that trading of the common stock of Horizon Lines will be suspended prior to the market opening on October 20, 2011. The stock is being suspended because it did not maintain an average market capitalization of at least $15 million over a consecutive 30-trading-day period, as required by NYSE continued listing standards. Horizon Lines is appealing the NYSE's determination. The company has been advised by the NYSE that additional action to pursue delisting of the stock will not be undertaken until the appeal is completed. In the meantime, the company's stock will trade on the OTCQB Marketplace under the new HRZL stock symbol.
