Reliance Steel & Aluminum Co. Reports Record 2007 First Quarter Results


    LOS ANGELES--(BUSINESS WIRE)--April 19, 2007--Reliance Steel &
Aluminum Co. (NYSE:RS) reported today its financial results for the
first quarter ended March 31, 2007. For the 2007 first quarter, net
income was a record $111.7 million, up 55% compared with net income of
$71.9 million for the 2006 first quarter. Earnings per diluted share
were a record $1.46 for the 2007 first quarter, compared with $1.07
for the 2006 first quarter. 2007 first quarter sales were $1.84
billion, an increase of 86% compared with 2006 first quarter sales of
$988 million. The 2007 first quarter financial results include in cost
of sales a pre-tax LIFO expense amount of $18.8 million, or $.15 per
diluted share, compared with a pre-tax LIFO expense amount of $5.0
million, or $.05 per diluted share in the 2006 first quarter. All
share and per share amounts have been adjusted for the two-for-one
common stock split effective July 19, 2006.

    David H. Hannah, Chief Executive Officer of Reliance said, "We are
very pleased with our 2007 first quarter results. Overall, customer
demand was steady throughout the quarter at what we consider to be a
healthy level. Our first quarter performance, as compared to 2006, was
most significantly impacted by our 2006 and 2007 acquisitions that
represented over $750 million of revenue in the 2007 first quarter."

    "During the quarter, we completed three acquisitions. They include
the Encore Group of metals service center companies (Encore Metals,
Encore Metals (USA), Inc., Encore Coils, and Team Tube in Canada)
headquartered in Edmonton, Alberta, Canada; Crest Steel Corporation, a
metals service center company headquartered in Carson, CA and
Industrial Metals and Surplus, Inc. a metals service center company
headquartered in Atlanta, GA and a related company, Athens Steel, Inc.
located in Athens, GA," Hannah said.

    "We also managed our working capital well during the quarter that
ended with net debt-to-total capital at 40.6%. Operating cash flow was
strong at about $71 million, up 72% from the 2006 first quarter. In
April of 2007, we exchanged the $600 million of notes that were issued
in November of 2006 for publicly traded notes registered with the
Securities and Exchange Commission," added Hannah.

    "We believe that our major markets including aerospace, energy,
non-residential construction, electronics and semiconductors, as well
as rail car and ship building will continue to grow, but at a slower
rate than in 2006. Additionally, we do not expect our costs and
pricing to change significantly as the year progresses. As a result,
we expect record sales and earnings in 2007 and currently estimate
earnings per diluted share for the 2007 second quarter in a range of
$1.45 to $1.55," 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 was paid on March 30 to
shareholders of record March 9. The Company has paid regular quarterly
dividends 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 $5,004 and
     $4,956 as of March 31, 2007 and December 31, 2006, 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. The 2006 calculation adjusted
     beginning shareholders' equity for $360.5 million of common stock
     and stock options issued to fund an acquisition on April 3, 2006.

(7) Calculations are based on the latest twelve months.
