Steel Dynamics Reports Record Sales and Earnings for First Quarter 2008

FORT WAYNE, INDIANA, April 21, 2008— Steel Dynamics, Inc. (NASDAQ-GS: STLD) today announced first quarter 2008 net income of $143 million, or $0.72 per diluted share, reflecting the company’s recent two-for-one stock split ($1.44 per diluted share on a pre-split basis). Net income increased 40 percent and net sales more than doubled to $1.9 billion, compared to the first quarter of 2007. Comparing first quarter 2008 results to the fourth quarter of 2007, net income grew 46 percent and net sales increased 31 percent. First quarter 2008 results benefit from the company’s acquisitions of The Techs (July 2007) and OmniSource Corporation (October 2007). All per-share figures reflect the company’s two-for-one-stock split effective on March 19, 2008.

A major factor positively impacting the quarter results is a significant improvement in steel operations results. First quarter steel shipments of 1.6 million tons reflect increased sequential shipping volumes by all six steelmaking operations. Flat-rolled steel shipments from the Flat Roll Division and The Techs were particularly strong, together totaling 947,000 tons, an increase of 109,000 tons, or 13 percent, compared to the fourth quarter of 2007. Shipments by the four long-products steel mills increased 7 percent sequentially.

Another significant impact on the quarter’s increased net sales and earnings is OmniSource Corporation. OmniSource was accretive to first quarter earnings by approximately $0.09 per diluted share. During the quarter, OmniSource experienced very strong demand for recycled ferrous scrap, both from the Steel Dynamics mills and from other mini mills, integrated steel mills, and foundries. Its favorable inventory posture entering the quarter put OmniSource in a position to capitalize on high scrap demand during the first quarter.

“SDI’s first quarter results exceeded our March 11 earnings guidance of $0.625 to $0.65 per diluted share, primarily due to the continued strengthening in the quarter of the flat-roll steel market and the metals recycling business,” said Keith Busse, Chairman and CEO. “Prices for both flat-rolled steel and scrap climbed faster and higher than we had anticipated, accelerating the margin growth we had predicted for the second quarter. Current market conditions suggest that resource cost increases can be offset by surcharges and selling price adjustments resulting in growing margins.

“Our outlook for 2008 continues to be very positive,” Busse said. “Even with weakness in the U.S. economy, we continue to see strong demand for flat-rolled steels, due principally to constrained domestic supply, low steel inventories, and limited steel imports. Second quarter backlogs for structural steel, merchant bars, and SBQ remain strong due to relatively steady demand as well as limited import activity. Likewise, we expect our metals recycling business to continue to perform well during this period of high demand for ferrous and non-ferrous recycled resources and pricing above historical levels. As long as global steel demand remains high and global steel prices meet or exceed U.S. prices, we should expect that steel imports into the U.S. will remain at a low level especially in light of a weak dollar.

“The path that resource costs and product pricing will take in the second half of the year is uncertain, although we believe that second quarter as well as third quarter domestic market conditions will remain favorable, allowing us to adequately recover any increase in costs. As a result, our preliminary earnings estimate for the second quarter of 2008 is in a range of $0.80 to $0.90 per diluted share,” Busse said.

First Quarter 2008 Operating Segment Information

The following highlights first quarter 2008 results for each of SDI’s three primary operating segments.

Steel Operations. Steel Operations remain SDI’s largest segment, representing 58 percent of the company’s first quarter net sales. This segment includes five steel mills and related steel processing facilities, such as The Techs. The Techs galvanize steel sheet that is sourced primarily from third parties. Other steel products included in this segment are produced in SDI’s electric-arc-furnace mini mills. Some flat-rolled and SBQ steels that SDI produces are finished in SDI facilities, utilizing various value-adding processes.

First quarter 2008 Steel Operations shipments were 1.6 million tons on net sales of $1.3 billion. Based on tons shipped, including steel shipments made by The Techs, flat-rolled products accounted for 58 percent of first quarter steel segment shipments, 18 percent was structural steel shipments, 9 percent was engineered bars, 9 percent was merchant bars, and 5 percent was Steel of West Virginia shipments. Operating income for the steel segment was $240 million, or $148 per ton shipped, compared to $131 per ton in the fourth quarter. These figures exclude profit-sharing costs.

The first quarter’s average selling price per ton for Steel Operations was $782, an increase of $72 per ton from $710 in the fourth quarter of 2007 and an increase of $136 from the year-ago quarter. Compared to the fourth quarter of 2007, the strongest increases in selling values were in flat-rolled steel products. The average scrap cost per net ton charged increased $50 compared to the fourth quarter, and was $82 higher than in the first quarter of 2007.

Scrap and Scrap Substitute Operations. This segment now includes ferrous and non-ferrous metals recycling by OmniSource Corporation (processing and trading) and SDI’s Iron Dynamics scrap-substitute operation producing pig iron for use by the Flat Roll Division. The segment also includes expenses related to the Mesabi Nugget project, which is currently under construction. The segment’s net sales for first quarter 2008 were $804 million, representing 37 percent of SDI’s first quarter net sales. Operating income for this segment was $54 million, excluding profit-sharing costs.

The first quarter of 2008 is the first to include full-quarter results for OmniSource Corporation as a part of Steel Dynamics. OmniSource is now the principal reporting entity in this segment. Because SDI’s fourth quarter results for this segment included a partial quarter for OmniSource (following the purchase of OmniSource on October 26, 2007), a meaningful quarter-to-quarter comparison of scrap operations is not possible.

For the first quarter, total ferrous scrap shipments, including shipments to SDI’s Steel Operations, were 1.4 million tons and non-ferrous scrap shipments were 239 million pounds. During the first quarter, the company’s scrap operations supplied 464,000 tons of ferrous scrap to SDI’s steel operations, or approximately 34 percent of the tonnage of ferrous scrap purchased by our mills during the quarter.

Steel Fabrication Operations. Steel Fabrication Operations includes five New Millennium Building Systems fabricating plants that produce joists, trusses, and steel decking used in the construction of non-residential buildings. First quarter net sales were $79 million, or 4 percent of SDI’s first quarter net sales. Operating income for this segment was $4 million, or $54 per ton shipped, excluding profit-sharing costs. First quarter shipments totaled 69,000 tons at an average selling price of $1,145 per ton. First quarter shipping volume and average selling price per ton for New Millennium products declined from the prior quarter, due to seasonal weakening in demand and a slowdown in projects related to residential construction. The three plants that were acquired as a part of the Roanoke Electric Steel acquisition in 2006 have been reconfigured to provide an improved cost structure and to expand their capabilities.  Margins at these facilities were weak to non-existent as a result of reconstruction and sagging market demand.   All five plants are well positioned to become stronger competitors in their regions, capable of generating stronger margins with any improvement in building demand.
