                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.  BASIS OF PRESENTATION

The preparation of financial statements in conformity with generally accepted
accounting principles requires that management make certain estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements. The reported amounts of revenues and expenses during the reporting
period may also be affected by the estimates and assumptions management is
required to make. Actual results may differ from those estimates.

In the opinion of management these estimates reflect all adjustments, consisting
of only normal recurring accruals, including elimination of all significant
intercompany balances and transactions, which are necessary to a fair statement
of the results for the interim periods covered by such statements. Certain
amounts from prior year financial statements have been reclassified to conform
to the current year presentation. These financial statements and notes should be
read in conjunction with the audited financial statements included in the
Company's 1997 Annual Report on Form 10-K.

4.  NEW ACCOUNTING PRONOUNCEMENTS


On January 1, 1998 the Company adopted Statement of Financial Accounting
Standard No. 130, "Comprehensive Income", which requires that separate
disclosure of certain items, including foreign currency translation adjustments
and gains and losses on certain securities be shown in the financial statements.
SFAS No. 130 does not require a specific format for the financial statement in
which comprehensive income is reported, but does require that an amount
representing total comprehensive income be reported in that statement. It has
been determined that the Company currently has no amounts which require
classification under comprehensive income.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS


RESULTS OF OPERATIONS

Net Sales

Net sales increased to $118.5 million in the first quarter of 1998 from $98.1
million in the first quarter of 1997, a 21% increase. The Company shipped 15%
more tons in the first quarter of 1998 as compared to the first quarter of 1997.
During 1997, the Company began producing and shipping value-added Cold Mill
products including pickled and oiled coils, cold-rolled coils, hot-rolled
galvanized coils and cold-rolled galvanized coils. During the first quarter of
1998, the Company shipped 168,330 tons of hot band and 153,379 tons of Cold Mill
product. Shipments of Cold Mill product did not begin until the third quarter of
1997 (44,817 tons).

Cost of Goods Sold

For the first quarter of 1998 and 1997, total cost of goods sold were $103.5
million and $73.8 million, respectively. Gross margin for the first quarter of
1998 and 1997 was $15.0 million and $24.2 million, respectively. As a percentage
of net sales, cost of goods sold was 87% and 75%, respectively. The $40 per ton
decrease in gross margin is primarily attributable to a $25 per ton decrease in
total per ton pricing in conjunction with a $11 per ton increase in scrap costs.

Selling, General and Administrative

Selling, general and administrative expense was $3.9 million and $5.3 million
for the first quarter of 1998 and 1997, respectively. The decrease in selling,
general and administrative expense is primarily due to the reduction in start-up
costs related to expansion projects and the reduction of amortization expense as
a result of the amended credit agreement that was finalized in the second
quarter of 1997.

During the first quarter of 1998, the Company entered into a ten year Reciprocal
License and Technology Sharing Agreement (the "License Agreement") with
Nakornthai Strip Mill Public Co. Limited (NSM) providing NSM with the right to
use the Company's technology in exchange for shares and warrants of NSM stock
valued at $15.5 million. The Company's ownership in NSM is recorded in Other
Assets at its estimated fair value. Income relating to the License Agreement was
deferred and is being recognized in income ratably over the ten year term of the
agreement. Concurrently, the Company entered into a ten year Management Advisory
and Technical Advisory Agreement to provide training and advice to a management
company under contract with NSM to manage NSM's mill in return for $2.0 million
annually. Such amount is payable in advance and is being recognized in income
ratably throughout each year of service.

Interest Expense

Interest expense totaled $3.3 million and $2.4 million for the first quarter of
1998 and 1997, respectively. The additional interest expense is a result of
additional borrowings to finance the expansion projects along with decreased
capitalized interest.

Other Income

Other income was $4.7 million and $1.0 million for the first quarter of 1998 and
1997, respectively. The increase in Other Income is primarily attributable to
nonrecurring services provided by the Company in connection with the NSM
transaction.

Taxes

The provision for income taxes for the first quarter of 1998 and 1997, was $4.9
million and $2.7 million, respectively. The tax provision for 1998 reflects the
Company at the statutory income tax rates. For 1997, the Company's effective tax
rate differed from the statutory rate as a result of the reduction in a deferred
tax valuation allowance.


LIQUIDITY AND CAPITAL RESOURCES

Steel Dynamics' business is capital intensive and requires substantial
expenditures for, among other things, the purchase and maintenance of equipment
used in its steelmaking and finishing operations and compliance with
environmental laws. The Company's liquidity needs arise primarily from capital
investments, working capital requirements and principal and interest payments on
its indebtedness. Since its inception, SDI has met these liquidity requirements
with cash provided by equity, long-term borrowings, state and local government
grants and capital cost reimbursements.

Net cash provided by operating activities totaled $5.1 million for the first
quarter of 1998. The cash provided from operating activities for the first
quarter of 1998 primarily related to net income and deferred taxes. During the
first quarter of 1997, the Company provided net cash of $38.0 million from
operating activities primarily from net income and decreased raw material
inventory due to increasing scrap costs. Management decided to build the raw
material inventory in the first quarter of 1998 due to decreasing scrap costs
and draw down the raw material inventory in the first quarter of 1997 due to
increasing scrap costs. Net cash used in investing activities totaled $47.1
million for the first quarter of 1998 and $46.3 million for the first quarter of
1997. Investing activities primarily consisted of capital expenditures of $46.9
million and $46.3 million for the first quarter of 1998 and 1997, respectively,
for the construction of the Company's existing facilities, the Cold Mill
Project, the Caster Project and the Iron Dynamics Project. Cash provided by
financing activities totaled $38.5 million for the first quarter of 1998 and
cash used in financing activities totaled $992,000 for the first quarter of
1997. The 1998 increase in cash provided by financing activities primarily
relates to the $41.2 million of proceeds from senior term debt. The $48.0
million in cash on hand at the end the first quarter of 1997 was carried over
from the initial public offering proceeds received in the fourth quarter of
1996.

ENVIRONMENTAL EXPENDITURES AND OTHER CONTINGENCIES

SDI has incurred and, in the future, will continue to incur capital expenditures
and operating expenses for matters relating to environmental control,
remediation, monitoring and compliance. Steel Dynamics believes that compliance
with current environmental laws and regulations is not likely to have a material
adverse effect on the Company's financial condition, results of operations or
liquidity; however, environmental laws and regulations have changed rapidly in
recent years and SDI may become subject to more stringent environmental laws and
regulations in the future.

INFLATION

SDI does not believe that inflation has had a material effect on its results of
operations.
