CALIFORNIA STEEL INDUSTRIES, INC.
AND SUBSIDIARY
Notes To Consolidated Condensed Financial Statements (Unaudited)

1.   Basis of Presentation
     ---------------------

     The accompanying unaudited consolidated condensed financial statements of
California Steel Industries, Inc. and its subsidiary as of and for the three and
nine months ended September 30, 1999 and 1998 have been prepared in accordance
with generally accepted accounting principles for interim financial information
and the rules and regulations of the Securities and Exchange Commission.
Accordingly, they do not include all of the information and footnotes required
by generally accepted accounting principles for complete financial statements.
However, the information reflects all adjustments (consisting only of normal
recurring adjustments) that, in the opinion of management, are necessary to
present fairly the financial position and results of operations for the periods
indicated.

     The accompanying unaudited consolidated condensed financial statements
should be read in conjunction with the audited consolidated financial statements
and notes thereto as of and for the years ending December 31, 1998 and 1997
contained in California Steel Industries, Inc.'s Amendment No. 3 to Registration
Statement on Form S-4 (File number 333-79587) filed with Securities and Exchange
Commission on September 29, 1999.

2.  New Accounting Pronouncements
    -----------------------------

    In June 1998, the Financial Accounts Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities" ("SFAS 133").  SFAS 133 establishes accounting and
reporting standards for derivative instruments, including derivative instruments
embedded in other contracts, and hedging activities.  SFAS 133, as amended by
SFAS 137, is effective for all fiscal quarters of fiscal years beginning after
June 15, 2000.  Application of this accounting standard is not expected to have
a material impact on our financial position, results of operations or liquidity.

3.  Inventories
    -----------

    Inventories are stated at the lower of cost (determined under the last-in,
first-out method of accounting) or market value.

4.   Long-Term Debt
     ---------------

     On April 6, 1999, we issued an aggregate of $150,000,000 of ten-year 8.5%
senior unsecured notes.  Interest is payable on the notes on April 1 and October
1, commencing October 1, 1999.  The notes are senior in right of payment to all
of our subordinated indebtedness and equal in right of payment to all of our
existing and future indebtedness that is not by its terms subordinated to the
notes. We may

                                       5
<PAGE>

redeem the notes at any time after April 1, 2004. The indenture governing the
notes contains covenants that limit our ability to incur additional
indebtedness, pay dividends on, redeem or repurchase capital stock and make
investments, create liens, sell assets, sell capital stock of certain of our
subsidiaries, engage in transactions with affiliates and consolidate, merge or
transfer all or substantially all of our assets and the assets of certain of our
subsidiaries on a consolidated basis.

     Proceeds from the notes were used to permanently repay outstanding bank
debt under a $10,000,000 term loan provided by The Dai-Ichi Kangyo Bank,
Netherlands, and a $50,000,000 revolving credit facility and a $80,000,000 term
loan, both provided by a syndicate of institutions led by the Industrial Bank of
Japan, Ltd., Los Angeles Agency.

          RESULTS OF OPERATIONS

Forward-Looking Statements
---------------------------

     Certain statements included in this Quarterly Report on Form 10-Q,
including without limitation statements containing the words "believes",
"intends", and "expects" and words of similar import, constitute "forward-
looking statements" within the meaning of the Private Securities Litigation
Reform Act.  Such forward-looking statements involve known and unknown risks,
uncertainties and other factors that may cause the actual results, performance
or achievements to differ materially from those expressed or implied by such
forward-looking statements.  A number of other factors may have a material
adverse effect on our financial performance.  These factors include a national
or regional slowdown which decreases the demand for our products, high levels of
steel imports, intense competition in our industry and uninsured risks such as
earthquakes.  Given these uncertainties, undue reliance should not be placed on
such forward-looking statements.  We disclaim any obligation to update any such
factors or to publicly announce the results of any revisions to any of the
forward-looking statements included herein to reflect future events or
developments.

     Net sales.  Net sales for the third quarter of 1999 increased by
$21,175,000 or 13.0%, compared to $162,391,000 in the third quarter of 1998. On
a year to date basis, net sales decreased by $4,301,000 or 0.8%, from
$519,125,000 for the nine months ending September 30, 1998 to $514,824,000 for
the nine months ending September 30, 1999.  The decrease is attributable to a
period to period reduction in the average selling price of our products due to
the lingering effects of import surges throughout 1998. Reduced sales prices in
both the third quarter and the nine months ending September 30, 1999 reduced net
sales by approximately $22,100,000 for three months ending September 30, 1999
and approximately $87,900,000 for the nine month period when compared to the
corresponding periods in 1998. The effects of decreasing sales prices have been
offset by higher sales volume and a better product mix emphasizing higher value
added galvanized steel. Our 1999 volume is higher as compared to 1998 on both a
quarter to quarter basis as well as a year to date basis. By increasing our
volume, we increased both third quarter net sales by approximately  $38,700,000
and year to date 1999 net sales by approximately $67,800,000. In addition, by
selling more galvanized products as a percentage of total products sold we
increased both third quarter net sales by approximately $4,700,000 and year to
date 1999 net sales by approximately $15,800,000. We have continued experiencing
slight sales price increases on hot rolled products and expect this trend to
continue for the balance of the year.

     Gross profit.  For the third quarter of 1999, gross profit increased by
$18,608,000, or 97.8%, compared to third quarter of 1998 and by $36,282,000, or
58.2%, from $62,394,000 for the nine months  ended September  30, 1998 to
$98,676,000 for the nine months ended September 30, 1999. Gross profit as a
percentage of net sales increased from 11.7% for the third quarter of 1998 to
20.5% for the same period in 1999 and from 12.0% for the nine months ended
September 30, 1998 to 19.2% for the same period in 1999. Our gross profit
increased as a result of (1) our slab costs decreasing at a faster rate than our
unit sales prices, (2) a product mix that included more of the higher value
added galvanized products and (3) higher sales volumes.  Additionally, during
the third quarter 1999, we recorded no LIFO adjustment versus a negative
adjustment of $732,000 to LIFO during the same period in 1998, reflecting a
decrease in inventory value. For the first nine months in 1999, we recorded a
$10,638,000 LIFO adjustment versus a $2,437,000 LIFO adjustment in the same
period in 1998, as a result of lower inventory costs. If we had used the FIFO
method of accounting instead, gross profit as a percentage of net sales would
have increased 12.2 % and remained the same at 20.5% for the third quarter of
1998 and 1999, respectively. Gross profit as a percentage of net sales would
have decreased to 11.7% for the nine month period ended September 30, 1998 and
17.1% for the nine months period ended September 30, 1999.

     Selling, general and administrative expenses.  Selling, general and
administrative expenses increased $870,000 from $6,706,000 in the third quarter
of 1998 to $7,576,000 in the third quarter of 1999 and increased $1,361,000 from
$21,298,000 for the first nine months of 1998 compared to $22,659,000 for the
same period in 1999. This increase resulted from a variety of miscellaneous
expenses, the majority of which consisted of an increase in the profit sharing
accrual due to higher profits and an increase in shipping expenses as a result
of higher volumes.

     Equity in income (loss) of affiliate. During the third quarter of 1999, we
recognized $197,000 of equity loss from our investment in Companhia Siderurgica
de Tubarao, which consists of our pro-rata share of Companhia Siderurgica de
Tubarao's loss, which amounted to $497,000 based on our 1.54% ownership interest
offset by $300,000 of amortized negative goodwill. Our investment in Companhia
Siderurgica de Tubarao is accounted for under the equity method of accounting.
Companhia Siderurgica de Tubarao is a publicly-traded Brazilian company engaged
in the production of steel slab. Approximately 95% of Companhia Siderurgica de
Tubarao`s products are exported outside of Brazil and sold predominantly in U.S.
dollars. This high percentage of U. S. dollar denominated cash flow tends to
lessen the impact of market risks related to fluctuations in currency exchange
rates.  For the same period in 1998, we recognized income of $1,663,000.

     Interest expense.  For the third quarter of 1999, our interest expense
decreased by $683,000 compared to the third quarter of 1998. Interest expense
decreased $942,000, or 7.2%, from $13,011,000 for the first nine months in 1998,
to $12,069,000 for the same period in 1999. The decrease in interest expense
resulted from a slight decrease in our average outstanding debt during the first
nine months of 1999 compared to the first nine months of 1998.  Interest expense
figures are net of interest income and capitalized interest of $296,000 for the
three months ended September 30, 1999 and $825,000 for the nine months ended
September 30, 1999 and $581,000 for three months ended September 30, 1999 and
$1,527,000 for the nine months ended September 30, 1998.

     Income taxes.  Income taxes increased $14,373,000 from  $12,396,000 for the
nine month period ended September 30, 1998 to $26,769,000 for the nine month
period ended September 30, 1999. Income taxes increased as a result of higher
income before tax in each period.

     Net income.  Net income for the three and nine month periods ended
September 30,1999 was $15,672,000 and $38,491,000 as compared to $4,814,000 and
$17,800,000 for the three and nine month periods ended September 30, 1998, for a
period to period increase of 225.6% and 116.2%, respectively.

Liquidity and Capital Resources
-------------------------------

     At September 30, 1999, we had $6,720,000 in cash and cash equivalents and
$42,926,000 available under our credit facility. During the nine months ended
September 30, 1999 cash flow from operations generated $63,694,000, which
consisted of $38,491,000 in net income, $18,937,000 in depreciation and
amortization expense and a net cash flow increase of $6,266,000 due to changes
in assets and liabilities, the majority of which were a $17,598,000 decrease in
inventories, a $15,519,000 increase in accounts receivable and a $13,734,000
increase in income taxes payable. Cash flow from investing activities during the
nine months ended September 30, 1999 consisted predominately of $26,734,000 of
capital expenditures. Cash flow from financing activities during the nine months
ended September 30, 1999 consisted of net repayments under both, issuance of
$150,000,000 of senior debt, short-term and long-term lines of credit and a
dividend payment of $8,630,000.

     At September 30, 1999, we had approximately $17,326,000 in material
commitments for capital investments. We estimate 1999 total capital expenditure
to be approximately $45,000,000.

     We anticipate that our primary liquidity requirements will be for working
capital, capital expenditures, debt service and payment of dividends. We believe
cash generated from operations and available borrowings under our bank facility
will be sufficient to enable us to meet our liquidity requirements for the next
12 months.

Year 2000
---------

     The Year 2000 problem is the result of computer programs being written
using two digits rather than four digits to define the applicable year.  In
1997, we began to examine our business for Year 2000 compliance.  The results of
our analysis and status of our Year 2000 compliance are summarized below.


Information and Non-Information Technology Systems
--------------------------------------------------

     Our significant non-information technology systems include water, electric,
telephones, sewer and waste-water discharge systems.  Our engineering department
has completed its analysis of all non-information technology systems that
support our business to determine the extent to which they are Year 2000
compliant.  We believe our non-information technology systems are year 2000
compliant. To date, testing has not revealed year 2000 exposure in our non-
information technology systems.

     We have three information technology systems which help us run our
business, including an administrative system, a production control system and a
process control system.  In the two years since we began to examine our systems
for Year 2000 compliance, we have developed a comprehensive program to address
potential Year 2000 problems with our information technology systems.  This
program includes three phases: assessment, remediation and testing.

     Assessment - This phase entails a comprehensive assessment of each of our
information technology systems with respect to Year 2000 problems.  Based on
testing we have undertaken since 1997, we have concluded that each of our three
information systems utilizes some date sensitive data.  Our administrative
system includes our accounting, human resources, purchasing, sales and shipping
functions.  Diagnostic testing by a third party vendor revealed that the
accounting, human resources and purchasing functions were purchased from an
outside vendor and were not Year 2000 compliant.  The other parts of our
administrative system were developed by us and our tests revealed that they are
Year 2000 compliant.  Testing conducted in 1998 revealed that our production
control system, which was developed in-house and which is used to schedule
production at our mills and to manage production data as it relates to sales
order entry, is Year 2000 compliant.  Our process control system, which is a

                                       9
<PAGE>

computer system that runs the production lines at each of our mills, was tested
in 1998 and 1999 and the testing revealed that two pieces of production
equipment have minor Year 2000 exposures.

     Remediation - This phase involves reprogramming or replacing our systems
that are exposed to Year 2000 problems.  We have purchased a Year 2000 compliant
software system known as an enterprise resource planning (ERP) system.  We
purchased the ERP system to replace the portions of our administrative system
that are not Year 2000 compliant and to modernize several aspects of our non-
production systems technology.  The ERP system has been installed and is
functioning well.   We have also developed and implemented remedial measures for
the two pieces of production equipment that we identified as having minor Year
2000 exposure.

     Testing - This phase involves testing the effects of our remediation
efforts.  All remedial measures have been implemented.  We will continue to test
our remediation efforts for the balance of the year.


Year 2000 Costs
---------------

     As of September 30, 1999, we have incurred approximately $1,600,000 in
costs related to implementing the ERP system.  The project is complete.  These
costs were capitalized to the extent permitted under generally accepted
accounting principles.  We do not anticipate further expenditures for Year 2000
preparations.


Third Party Relationships
-------------------------

     Our material third party relationships are with slab suppliers, including
foreign suppliers.  We have contacted our major suppliers and they have
confirmed to us that they are all Year 2000 compliant.

     We have also sent surveys to the vendors from which we made 85% of our 1998
purchases to determine their preparedness for the Year 2000.  Of the 104 surveys
we sent, we have received 72 responses.  These responses have been evaluated to
determine whether and the extent to which these suppliers are Year 2000
compliant.  Results of such evaluations are being used to fine tune our
contingency plans.

     We have not contacted our customers to assess their Year 2000 compliance
and we do not intend to do so.  Because no single customer represents more than
ten percent of our total sales, we do not anticipate material problems with any
potential Year 2000 exposure our customers might have.  Our sales to foreign
customers amount to less than one percent of our total sales, therefore, we are
not exposed to material risks from foreign customers' potential Year 2000
problems.

     We have not independently verified or validated the accuracy of third
parties' assessments of their Year 2000 risk and cost estimates.


Worst Case Scenario and Contingency Plan
----------------------------------------

     We believe we have taken and continue to take all prudent steps to identify
and remediate our Year 2000 exposure and that we have an effective program in
place to address any Year 2000 problems in a timely manner.  Our expectations
regarding our Year 2000 efforts, however, are subject to various uncertainties
that could cause actual results to differ from those discussed here.  Those
uncertainties include our success in identifying systems that are not Year 2000
compliant and the success of vendors, suppliers, customers and other third
parties with which we interact in addressing any Year 2000 problems they might
have.  We believe that our most reasonable worst case scenario is that there
could be some

                                       10
<PAGE>

interruptions in deliveries from our third party vendors and possibly in our
interactions with customers, to the extent that they have their own Year 2000
problems.

     We maintain a general contingency plan for emergencies and have updated
this plan to deal with the Year 2000 problem.  In this regard, each of our
departments is responsible for ensuring that they have back-up capabilities to
eliminate or minimize the negative effects of emergencies.  In addition, we
maintain inventories capable of supporting sales activities for approximately
sixty days with an additional thirty days of inventory in transit to our
facilities at any given time.  Our contingency efforts are being carried out by
a team of employees led by our manager of information technology. As an
additional precaution we will not be operating any production equipment at year-
end.
