AK Steel Updates Third Quarter 2010 Outlook
WEST CHESTER, OH, September 15, 2010—AK Steel (NYSE: AKS) today said it is revising its
outlook for the third quarter of 2010, which was originally issued with its second quarter 2010
earnings results on July 27, 2010. The company’s revised third quarter outlook primarily reflects costs
associated with the acceleration of planned maintenance work at its Ashland (KY) blast furnace, as
well as higher raw material and operating costs than were expected at the time of its previous
guidance.
Updates to Third Quarter 2010 Outlook
The company said it is now planning to take an 11-day maintenance outage on its blast furnace in
Ashland, Kentucky, beginning approximately September 20, 2010. This outage was previously
planned to occur in the first-half of 2011, but has been advanced due to furnace conditions. Further,
the company now anticipates higher raw material and operating costs in the third quarter, as well as a
modest increase in the costs associated with an environmental remediation project.
The impact of these changes on the company’s original guidance for the third quarter would
result in an operating loss of approximately $20 per ton for the third quarter of 2010. The company’s
original guidance was for an operating profit of $15 per ton for the third quarter. Nearly half of the
lower expected financial results for the third quarter are attributable to the acceleration of the Ashland
blast furnace outage.
Additional Update Regarding Iron Ore Costs
Iron ore is one of the company’s principal raw materials, and the price AK Steel pays for iron ore
under the contracts with its three major iron ore suppliers is based upon an annual global iron ore
benchmark price. To date, no annual global benchmark price for iron ore has been established by the
industry for 2010. In the absence of such a global benchmark price for 2010 iron ore purchases, the
company used an assumed 65% increase from the 2009 benchmark price for purposes of its second
quarter 2010 financial results and third quarter outlook.
While AK Steel still cannot reliably predict a 2010 global iron ore benchmark price, the
company now believes that the year-over-year increase in any such benchmark, if and when it is
established, likely will be higher than 65%. The effect of any such increase in the benchmark beyond
65% would be in addition to the changes in anticipated third quarter earnings addressed in the
preceding update section. AK Steel has previously said, and reiterates with this revised outlook, that
every five percentage points of variation (up or down) from its assumed year-over-year benchmark iron
ore price increase of 65% would impact the company’s third quarter 2010 results by approximately
$11 million, or approximately $7 per ton.
