FORT WAYNE, INDIANA, October 11, 2005 —Steel Dynamics, Inc. (NASDAQ:STLD) is pleased to announce that the company and its employees are donating more than $100,000 to benefit the people displaced by Hurricane Katrina. This contribution is being made to the Red Cross Hurricane Katrina Fund.

Soon after Hurricane Katrina struck the gulf states, numerous customers and suppliers with facilities in the affected region informed SDI of the hurricane’s damage and destruction. SDI employees responded with a coordinated effort to raise funds to help victims of the hurricane, in addition to the personal contributions employees were making through their churches and other organizations.

“It is very gratifying to see SDI employees stepping up to help other Americans in need,” said Keith Busse, President and CEO of Steel Dynamics. “Thousands of people in the gulf states face a very difficult challenge rebuilding and returning their lives to normalcy. We trust that our contribution will be of assistance to speed their recovery.”
