    LOS ANGELES--(BUSINESS WIRE)--Oct. 20, 2005--Reliance Steel &
Aluminum Co. (NYSE:RS) reported today its financial results for the
third quarter and nine-months ended September 30, 2005. For the 2005
third quarter, net income was $49.4 million, up 12% compared with net
income of $44.1 million for the same period in 2004. Earnings per
diluted share were $1.49 for the quarter ended September 30, 2005, up
10% compared with earnings of $1.35 per diluted share for the same
period last year. Sales for the 2005 third quarter were a record
$870.1 million, up 11% compared with 2004 third quarter sales of
$783.7 million. The 2005 third quarter financial results include in
cost of sales a pre-tax LIFO expense amount of $4.0 million, or $.07
per diluted share, compared with a pre-tax LIFO expense amount of
$32.5 million, or $.60 per diluted share in the 2004 third quarter.
    For the nine-months ended September 30, 2005, net income amounted
to a record $144.8 million, up 14% compared with net income of $126.8
million for the same period in 2004. Earnings per diluted share were
$4.38 for the nine-months ended September 30, 2005, up 13% compared
with earnings of $3.88 per diluted share for the nine-months ended
September 30, 2004. Sales for the 2005 year-to-date period were a
record $2.5 billion, an increase of 14% compared with 2004 nine-month
sales of $2.2 billion. The 2005 nine-month financial results include
in cost of sales a pre-tax LIFO expense amount of $16.5 million, or
$.31 per diluted share, compared with a pre-tax LIFO expense amount of
$92.5 million, or $1.72 per diluted share in the 2004 year-to-date
period.
    David H. Hannah, Chief Executive Officer, said, "Our products sold
into the aerospace industry continued to show strength during the
quarter. We also had the benefit of our Chapel Steel acquisition that
was completed on July 1, 2005. Additionally, we experienced a small
improvement in volume and pricing for our carbon steel products late
in August and through September, as a result of the producers' price
increase announcements. Customer demand and pricing for our other
metal products remained steady throughout all end markets.
    "We do not expect any significant changes in either pricing or
demand for the fourth quarter other than the typical seasonal
slowdown. At this time, we estimate earnings per diluted share for the
2005 fourth quarter will be in a range of $1.10 to $1.20," concluded
Hannah.
    On October 10, 2005, the Company announced that it reached an
agreement with New Wave Technologies Ltd. ("New Wave"), a Singapore
public company, and its associate, Manufacturing Network Pte. Ltd.
("MNPL"), based in Singapore, to form a joint venture company,
Reliance Pan Pacific, Pte. Ltd. Reliance Pan Pacific will be 70% owned
by Reliance Steel & Aluminum Co. and 30% owned by MNPL. Upon
completion of the transaction, it is expected that, subject to
regulatory approvals, MNPL will sell its 100% interest in Everest
Metals (Suzhou) Co., Ltd., a Chinese metals service center company, to
Reliance Pan Pacific.
    Everest Metals was formed in 2001 and began processing and
distributing primarily aluminum products to the electronics industry
in 2002. Everest's 2004 revenues were approximately $2.5 million. The
transaction is expected to be finalized in early 2006, subject to the
successful completion of due diligence and regulatory approvals,
including the approvals of the People's Republic of China and the
shareholders of New Wave.
    On July 20, 2005, the Company's Board of Directors declared an 11%
increase in the regular quarterly cash dividend to $.10 per share of
common stock. The dividend was paid on September 2, 2005 to
shareholders of record August 12, 2005. Over the past five quarters,
the regular quarterly dividend payment has increased in total $.04 per
share or 67%. The Company has paid regular quarterly dividends for 45
consecutive years.

    (1)Operating profit is calculated as net sales less cost of sales,
warehouse, delivery, selling, general and administrative expenses and
depreciation expense.
    (2)See Consolidated Statements of Income for reconciliation of
EBIT and EBITDA. EBIT is defined as the sum of income before interest
expense and income taxes. EBITDA is defined as the sum of income
before interest expense, income taxes, depreciation expense and
amortization of intangibles. We believe that EBIT and EBITDA are
commonly used as a measure of performance for companies in our
industry and are frequently used by analysts, investors, lenders and
other interested parties to evaluate a company's financial performance
and its ability to incur and service debt. EBIT and EBITDA should not
be considered as a measure of financial performance under accounting
principles generally accepted in the United States. The items excluded
from EBIT and EBITDA are significant components in understanding and
assessing financial performance. EBIT or EBITDA should not be
considered in isolation or as an alternative to net income, cash flows
generated by operating, investing or financing activities or other
financial statement data presented in the consolidated financial
statements as an indicator of operating performance or as a measure of
liquidity.
    (3)The December 31, 2004 balances have been adjusted to reflect
balance sheet reclassifications made as of September 30, 2005.
    (4)Net debt-to-total capital is calculated as total debt (net of
cash) divided by shareholders' equity plus total debt (net of cash).
    (5)Calculations are based on the latest twelve months.
