STEEL DYNAMICS ANNOUNCES 4TH QUARTER & ANNUAL 2001 FINANCIAL RESULTS

Fort Wayne, Indiana, February 5, 2002 -- Today Steel Dynamics, Inc. (NASDAQ:
STLD) announced 2001 annual consolidated earnings of $4.5 million, or $0.10 per
diluted share. SDI's annual sales revenue was $607 million, on consolidated
shipments of 2.0 million tons during 2001, as compared with annual sales revenue
of $693 million, on shipments of 1.9 million tons during 2000. During the year,
capital expenditures were $91 million and start-up costs were $20 million, all
primarily related to our structural and rail manufacturing facility and our
steel scrap substitute facility.

"Market conditions within the U.S. steel industry made 2001 our most challenging
year," stated Keith Busse, president and chief executive officer. "Due to the
continued dumping of unfairly traded foreign steel into the U.S. market,
combined with the weakened U.S. economy, the industry experienced historically
low steel selling prices and tightened margins. Numerous American steel related
businesses filed for bankruptcy during the past several years, although SDI
remains one of a very small group of American steel manufacturers that achieved
profitability for the year, and we look forward to what we believe will be a
much improved 2002.

"We have already experienced significant strengthening in our order backlog.
After reaching a low-water mark in the fourth quarter, spot selling prices have
now rebounded. A $20 increase announced in December 2001, which took affect in
the first quarter 2002 has held, and we should benefit from additional price
increases throughout 2002."

In June of 2001 the Bush Administration initiated a Section 201 action, which
resulted in the U.S. International Trade Commission (ITC) ruling that the U.S.
steel industry had been seriously injured due to increased steel imports. In
March 2002, SDI hopes the Administration will take action to provide
comprehensive import relief, with expected positive effects for the U.S. steel
industry beginning in the second quarter. Separately, as a result of trade case
filings by SDI and other American steel companies, the ITC in 2001 found injury
by foreign countries importing hot-rolled and cold-rolled sheet. These
determinations have led to duties on future imports of hot roll products and are
expected to lead to duties on cold-rolled sheet as well. Steel Dynamics believes
the outcome of these cases will help to stabilize the steel marketplace by
reducing the volume of unfairly priced imported steel, thereby allowing domestic
market pricing to return to more profitable levels.

Busse concluded, "Steel Dynamics is one of the lowest cost steel producers in
existence today, with state-of-the-art production facilities and extraordinary
employee resources. We believe that we are one of the best-positioned companies
within our industry to most quickly realize the anticipated positive benefits
associated with an improving economy, positive trade case results, and a
potentially favorable Section 201 ruling,"

FOURTH QUARTER HIGHLIGHTS

In the fourth quarter 2001, SDI reported its first quarterly operating loss
since achieving profitability in 1996, recording a net loss of $3.9 million.
SDI's sales for the fourth quarter 2001 were $138 million, on consolidated
shipments of 465,000 tons, in comparison with sales of $152 million and
consolidated shipments of 459,000 tons during the same period in 2000.

SDI incurred a charge of $3.4 million related to the anticipated uncollectable
accounts receivable associated with the Metals USA bankruptcy during the fourth
quarter 2001, accounting for approximately $0.05 of our fourth quarter reported
loss per diluted share of $0.09. Capital expenditures of $39 million and
start-up costs of $3 million were primarily related to our structural and rail
manufacturing facility.

STRUCTURAL & RAIL MILL CONSTRUCTION

In late May of 2001, SDI commenced construction of its structural and rail
manufacturing facility, located in Whitley County, Indiana. Construction costs
have remained within our capital budget and construction is ahead of schedule.
We are expecting to begin test production of our structural products during the
second quarter of 2002 and to initiate rail production during the first quarter
of 2003. This facility offers SDI an opportunity to complement its flat-roll and
fabricated steel businesses with additional high-margin products, providing
increased cyclical earnings stability through further market diversification.

FINANCING MATTERS

On January 28, 2002, SDI and its Iron Dynamics subsidiary entered into a
settlement agreement with IDI's senior secured bank lenders to retire the
existing IDI bank debt of approximately $59 million, subject to satisfying
certain conditions. The agreement requires SDI to pay $15 million in cash on
February 1, 2002, to issue $22 million of Steel Dynamics' common stock in March
2002, and to make contingent future payments retiring the balance of the
obligation, if and to the extent that IDI resumes operations and generates
earnings, as defined in the agreement.

SDI is also actively pursuing a plan of refinancing of the Steel Dynamics'
senior secured and unsecured credit facilities and expects to have the
refinancing completed before the end of March 2002.

STEEL DYNAMICS, INC., BASED IN FORT WAYNE, INDIANA, PRODUCES A BROAD RANGE OF
FLAT-ROLLED STEEL PRODUCTS, INCLUDING LIGHT-GAUGE, MICRO-ALLOYED AND
HIGH-STRENGTH STEELS AT ITS MINI-MILL IN BUTLER, INDIANA. PRODUCTS INCLUDE
HOT-BAND, COLD-ROLLED AND COATED STEEL SHEET.
