Feb. 1, 2006 — United States Steel Corp.’s Board of Directors has approved the repurchase of up to 8 million shares of its common stock.

Commenting on the new repurchase program, U. S. Steel President and CEO John Surma said, "Since initially announcing the stock repurchase last July, U. S. Steel has purchased 5.8 million shares. By replenishing our program at 8 million shares we continue to show our commitment to our shareholders and our long term optimism for our company."

This repurchase authorization replaces the repurchase program announced July 26, 2005. It is expected that the purchases will be made from time to time in open-market or privately negotiated transactions. The timing of such purchases will be determined by the company based upon a number of factors including the market price of United States Steel Corp. common stock; the availability and pursuit of strategic initiatives including investment and acquisition opportunities; operating cash flow and internal capital requirements; and general economic conditions in the United States and Europe.
