<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">On April&nbsp;12, 2006,
Steel Dynamics,&nbsp;Inc. issued a press release entitled &#147;Steel Dynamics
Completes Acquisition of Roanoke Electric Steel Corporation.&#148; The full text of
the press release is furnished herewith and attached hereto as Exhibit&nbsp;99.1.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Steel Dynamics completed
its previously announced acquisition of Roanoke Electric Steel Corporation on April&nbsp;11,
2006, immediately following approval of the transaction by Roanoke stockholders.
Pursuant to the Merger Agreement, Roanoke stockholders received $9.75 in cash
and 0.4 shares of SDI common stock for each share of Roanoke stock outstanding
at the effective date of the merger. Based on 11,360,901 Roanoke shares
outstanding prior to the close of the transaction, Steel Dynamics paid $111
million in cash, issued 4,544,360 shares of registered Steel Dynamics common
stock and assumed $45 million in Roanoke debt, which the company intends to
retire within the next few days. The cash portion of the purchase price was
funded from the company&#146;s current cash on hand. After giving effect to the
issuance of shares related to this transaction, Steel Dynamics will have a
total of 48,611,177 shares of common stock outstanding.</font></p>

Electric Steel Corporation</font></b></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="font-size:10.0pt;margin:0in 0in .0001pt;"><i><font size="2" face="Times New Roman" style="font-size:10.0pt;font-style:italic;">FORT WAYNE,
INDIANA</font></i>, April&nbsp;12, 2006 &#150; Today Steel Dynamics,&nbsp;Inc.
(NASDAQ:STLD) announced that it has completed its previously announced
acquisition of Roanoke Electric Steel Corporation (NASDAQ:RESC). The
transaction closed on April&nbsp;11, 2006, immediately following approval of
the transaction by Roanoke stockholders.</p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Pursuant to the Merger Agreement, Roanoke stockholders
received $9.75 in cash and 0.4 shares of SDI common stock for each share of
Roanoke stock outstanding at the effective date of the merger. Based on
11,360,901 Roanoke shares outstanding prior to the close of the transaction,
Steel Dynamics paid $111 million in cash, issued 4,544,360 shares of registered
Steel Dynamics common stock and assumed $45 million in Roanoke debt, which the
company intends to retire within the next few days. The cash portion of the
purchase price was funded from the company&#146;s current cash on hand. After giving
effect to the issuance of shares related to this transaction, Steel Dynamics
will have a total of 48,611,177 shares of common stock outstanding.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The combined companies will now operate five
electric-furnace mini mills with annual production capacity of approximately 5
million tons, whose steel products include flat-rolled, merchant bar,
engineered bar, and light structural steels as well as wide-flange beams and
rail. In addition, the company will now operate five facilities that fabricate
steel joists and decking used in non-residential construction and two
scrap-metal processing facilities. Steel Dynamics now operates facilities in
the states of Indiana, Virginia, West Virginia, South Carolina, Florida, Ohio,
and Tennessee.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Keith Busse, President and CEO of Steel Dynamics said, &#147;We
believe this acquisition will significantly broaden our steel product offerings
and give us a much stronger platform&nbsp;to serve our joist-and-deck
customers. We will begin immediately to invest in the joist-and-deck operations
to improve their productivity and product capabilities. We see excellent
prospects for continued volume growth in this segment of our business. At the
same time, we expect to make capital improvements in the Roanoke
steel-producing facilities to improve efficiency and ultimately to support
higher volumes of production.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&#147;We welcome Roanoke&#146;s employees to Steel Dynamics and are
confident that they will become strong contributors to Steel Dynamics&#146;
continued growth and success,&#148; Busse concluded.</font></p>
