AK Steel Named World-Class Steelmaker

West Chester, OH, June 24, 2008—AK Steel (NYSE: AKS) has been added to the list of "World-Class Steelmakers," reflecting the company's extraordinary turnaround since 2003, according to World Steel Dynamics (WSD), a steel industry strategic information service. The announcement was made at this week's Steel Success Strategies conference held in New York that was attended by more than 1,400 steel industry executives from around the world.

In making the announcement, Peter F. Marcus, managing partner of WSD, said, "AK Steel's common stock when Jim Wainscott was appointed president and CEO in 2003 was under $2 per share. Share performance has since been stellar, trading at over $73 per share in the last month. In addition, AK Steel's operating profit per ton is now the highest among the USA integrated producers and its balance sheet is remarkably improved."

Marcus noted that the company has leading market positions in high value-added products, including automotive sheet products, stainless steel for automotive exhaust applications, and the highest valued-added silicon electrical steels. He added that AK Steel is consistently rated at the top of its class in product quality by customers, according to independent surveys.

"We are excited and honored that AK Steel has been named to WSD's prestigious list of World- Class Steelmakers," said James L. Wainscott, chairman, president and CEO of AK Steel. "Attaining recognition as one of the finest steel producers on the planet is a tribute to the hard work and dedication of AK Steel's outstanding board of directors, management team and employees."
