  <p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">At the Steel Dynamics annual meeting of shareholders
  on May&nbsp;22, 2008, President and Chief Executive Officer Keith E. Busse, in
  his &#147;Outlook for 2008,&#148; estimated that, even with the nation facing the
  possibility of a moderate recession, but taking into account the company&#146;s
  recent and proposed acquisitions, as well as stronger shipping volumes and
  higher steel and scrap selling values, Steel Dynamics&#146; revenues ought to be
  over $8 billion for the year.</font></p>

  <p style="margin:0in 0in .0001pt;text-autospace:none;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Mr.&nbsp;Busse went on to state that, if the current
  domestic steel market conditions persist through 2008, with a low level of
  imports, increased exports, the continued weak dollar, a steady but not growing
  domestic demand for steel and continued strong steel selling values, he would
  maintain the company&#146;s April&nbsp;earnings guidance of $0.80 to $0.90 per
  diluted share for the second quarter, but would increase the company&#146;s current
  expectations for full-year 2008 earnings to a range of $3.00 to $3.25 per
  diluted share.</font></p>

  Item
  7.01.  Regulation FD Disclosure.
  At the Steel Dynamics annual meeting of shareholders
  on May 22, 2008, President and Chief Executive Officer Keith E. Busse, in
  his "Outlook for 2008," estimated that, even with the nation facing the
  possibility of a moderate recession, but taking into account the company's
  recent and proposed acquisitions, as well as stronger shipping volumes and
  higher steel and scrap selling values, Steel Dynamics' revenues ought to be
  over $8 billion for the year.
  Mr. Busse went on to state that, if the current
  domestic steel market conditions persist through 2008, with a low level of
  imports, increased exports, the continued weak dollar, a steady but not growing
  domestic demand for steel and continued strong steel selling values, he would
  maintain the company's April earnings guidance of $0.80 to $0.90 per
  diluted share for the second quarter, but would increase the company's current
  expectations for full-year 2008 earnings to a range of $3.00 to $3.25 per
  diluted share.
