Reliance Steel & Aluminum Co. Reports Record 2006 Fiscal Year Results;
                          Net Income up 73%


    LOS ANGELES--(BUSINESS WIRE)--Feb. 15, 2007--Reliance Steel &
Aluminum Co. (NYSE:RS) reported today its financial results for the
fiscal year and fourth quarter ended December 31, 2006. For the fiscal
year ended December 31, 2006, net income amounted to a record $354.5
million, up 73% compared with net income of $205.4 million for the
same period in 2005. Earnings per diluted share were a record $4.82
for the year ended December 31, 2006, compared with earnings of $3.10
per diluted share for the year ended December 31, 2005. Sales for the
2006 fiscal year were also a record at $5.7 billion, an increase of
71% compared with 2005 fiscal year sales of $3.4 billion. The 2006
fiscal year financial results include in cost of sales a pre-tax LIFO
expense amount of $94.1 million, or $.79 per diluted share, compared
with a pre-tax LIFO expense amount of $16.6 million, or $.15 per
diluted share in the 2005 period.

    All share and per share amounts have been adjusted for the
two-for-one common stock split effective July 19, 2006. The 2006
financial results include positive contributions to sales and earnings
from the Company's 2006 acquisitions, primarily Yarde Metals, Inc.
that was acquired on August 1, 2006 and Earle M. Jorgensen Company
that was acquired on April 3, 2006. The Jorgensen acquisition included
the issuance of approximately nine million shares of Reliance's common
stock, representing a 14% increase in diluted shares outstanding.

    For the 2006 fourth quarter, net income was $74.6 million, up 23%
compared with net income of $60.6 million for the 2005 fourth quarter.
Earnings per diluted share were $.98 for the 2006 fourth quarter and
$.91 for the 2005 fourth quarter. 2006 fourth quarter sales were $1.6
billion, an increase of 81% compared with 2005 fourth quarter sales of
$868.7 million. The 2006 fourth quarter financial results include in
cost of sales a pre-tax LIFO expense amount of $37.9 million, or $.31
per diluted share, compared with a pre-tax LIFO expense amount of
$91,000 recorded in the 2005 fourth quarter.

    David H. Hannah, Chief Executive Officer of Reliance said, "We are
very pleased with our fiscal year 2006 results. All of our end markets
were strong with a very favorable operating environment throughout our
network of facilities. We completed four acquisitions during 2006,
including the acquisition of Earle M. Jorgensen Company on April 3,
2006 that was our largest acquisition to-date and our first
acquisition of a public company. The purchase price consisted of
approximately 50% common stock and 50% cash. We also acquired Yarde
Metals, Inc. on August 1, 2006, our second largest acquisition. The
combined sales of Jorgensen and Yarde contributed $1.6 billion to our
2006 revenues.

    "We have completed three additional acquisitions in January and
February of 2007 that further increase our product and geographic
diversification. We acquired Crest Steel Corporation with 2006
revenues of approximately $133 million and Industrial Metals and
Surplus, Inc. with 2006 revenues of approximately $105 million, on
January 2, 2007. Crest has facilities in California and Arizona and
processes and distributes carbon steel products including flat-rolled,
plate, bars and structurals. Industrial Metals is located in Georgia
and specializes in the processing and distribution of carbon steel
structurals, flat-rolled and ornamental iron products. We acquired the
Encore Group of metals service centers located mainly in Western
Canada as of February 1, 2007. Encore, with 2006 revenues of
approximately C$259 million, specializes in the processing and
distribution of alloy and carbon bar and tube, as well as stainless
steel sheet, plate and bar and carbon steel flat-rolled products that
serve, among others, the robust energy, oil and gas industries,"
Hannah said.

    "We experienced the normal seasonal slowdown during the 2006
fourth quarter. However, gross profit margins were slightly below our
earlier expectations due to some inventory de-stocking that resulted
in added competitive pressures. Also, our LIFO expense during the
quarter was substantially higher than we anticipated, despite the fact
that we reduced our inventories during that time. Stainless steel
prices continued to increase from their historical highs in the third
quarter which we did not expect to happen, resulting in the
significant LIFO expense of $37.9 million, or $.31 per diluted share
in the fourth quarter, exceeding our earlier estimate by $19.1
million, or $.16 per diluted share," said Hannah.

    "In November of 2006, we replaced our $700 million credit facility
with a $1.1 billion five-year, unsecured syndicated credit facility
that provides increased availability of funds and more favorable
pricing. This facility may be increased to up to $1.6 billion at our
request with approval from the lenders. We used funds from the
increased line to purchase approximately $250 million of the Jorgensen
9.75% senior secured notes in a tender offer. We then issued $600
million of senior unsecured notes and used the proceeds to pay down
the borrowings under our credit facility. This included $350 million
of 10 year notes at 6.20% and $250 million of 30 year notes at 6.85%.
The notes are investment grade rated Baa3 by Moody's and BBB- by
Standard & Poor's. These activities lowered our cost of capital and
significantly increased our availability to fund our working capital
and general corporate needs, including acquisitions, capital
expenditures, debt repayments, dividend payments and stock
repurchases," Hannah stated.

    "We are optimistic regarding 2007 business conditions. We
generally see continued growth in the markets we serve, but at a
slower rate than in 2006. Pricing should be relatively stable with
steel trending upwards and aluminum slightly softer as the year
progresses. Our 2006 and 2007 acquisitions to-date should increase
2007 revenues by about $1 billion compared to 2006, assuming no
significant changes in the operating environment. As a result, we
expect record sales and earnings again in 2007 and currently estimate
earnings per diluted share for the 2007 first quarter in a range of
$1.25 to $1.35," Hannah concluded.

    On February 14, 2007, the Board of Directors declared a 33%
increase in the regular quarterly cash dividend to $.08 per share of
common stock. The 2007 first quarter dividend is payable on March 30,
2007 to shareholders of record March 9, 2007. The Company has paid
regular quarterly dividend payments for 47 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) All periods have been adjusted to reflect the two-for-one stock
     split effected in the form of a 100% stock dividend that was
     declared on May 17, 2006 and distributed on July 19, 2006 to
     shareholders of record on July 5, 2006.

(4) Long-term debt includes capital lease obligations of $4,956 and
     $5,515 as of December 31, 2006 and December 31, 2005,
     respectively.

(5) Net debt-to-total capital is calculated as total debt (net of
     cash) divided by shareholders' equity plus total debt (net of
     cash).

(6) Calculations are based on the latest twelve months net income and
     beginning shareholders' equity, adjusted for $360.5 million of
     common stock and stock options issued to fund an acquisition on
     April 3, 2006.
