Company Receives MANNY Award From Cincy Magazine

West Chester, OH, March 12, 2008—AK Steel (NYSE: AKS) has received a MANNY award for excellence in manufacturing from Cincy magazine, a leading business publication in Greater Cincinnati. The award recognizes the company for its "Breakthrough" performance in 2007.

Although faced with historically high raw material and energy costs, AK Steel led all U.S. integrated steelmakers in adjusted operating profitability in 2007. As a result of its cost-control efforts, liability-reduction initiatives and asset maximization strategy, the company is once again on solid financial footing.

"We are honored to receive a MANNY award from Cincy Magazine," said James L. Wainscott, AK Steel chairman, president and CEO. "For AK Steel, 2007 was a breakthrough year defined by record performances across all of our key metrics, including safety, quality, productivity and financial results. I congratulate and thank all of our employees for their contributions to AK Steel's success."

The MANNY awards honor Cincinnati manufacturers across five key areas of success: Job creation, work environment, innovation, breakthroughs and growth. Award recipients were selected by an independent panel assembled by Cincy magazine.

In addition to the MANNY award, AK Steel was listed among FORTUNE magazine's "America's Most Admired Companies" in 2008, receiving a number-one ranking in the metals sector for product quality and use of corporate assets. The company was also listed among CNNMoney.com's Top 10 Best Performing FORTUNE 500 stocks for the year 2007. With a 174% gain in value, AK Steel claimed the second spot on this prestigious list.
