Dec. 18, 2006 — United States Steel Corp. announced plans to withdraw the listing of its common stock from NYSE Arca, Inc., formerly the Pacific Exchange.

The company says its decision to withdraw its listing from NYSE Arca to streamline operations and eliminate duplicative administrative requirements that have resulted from the NYSE Group's recent merger with Archipelago Holdings, the parent company of NYSE Arca, Inc. The withdrawal is expected to be effective within the next month.

United States Steel notes that the company does not believe that withdrawing its listing from NYSE Arca will have any impact on the liquidity of its stock. NYSE Arca, Inc. will continue to trade United States Steel Corp. stock on an unlisted trading privilege basis.

The company says its common stock will continue to be listed on the New York Stock Exchange.
