SEPTEMBER 30, 2012

1.  Basis of Presentation

Principles of Consolidation

The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and with the instructions of Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments, consisting only of normal recurring adjustments necessary for a fair presentation with respect to the interim financial statements, have been included. The results of operations for the nine months ended September 30, 2012 are not necessarily indicative of the results for the full year ending December 31, 2012. For further information, refer to the consolidated financial statements and footnotes thereto for the year ended December 31, 2011, included in Reliance Steel & Aluminum Co.’s (“We”, “Reliance” or the “Company”) Annual Report on Form 10-K.

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts and the disclosure of contingent amounts in our consolidated financial statements and the accompanying notes. Actual results could differ from those estimates.

Our consolidated financial statements include the assets, liabilities and operating results of majority-owned subsidiaries. The ownership of the other interest holders of consolidated subsidiaries is reflected as noncontrolling interests. Our investments in unconsolidated subsidiaries are recorded under the equity method of accounting. All significant intercompany accounts and transactions have been eliminated.

2.  Impact of Recently Issued Accounting Guidance

Accounting Guidance Recently Adopted

On January 1, 2012, we adopted changes issued by the Financial Accounting Standards Board (“FASB”), which require companies to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income, or in two separate but consecutive statements. We elected to adopt the two-statement option. The new guidance eliminated the option to present the components of other comprehensive income as part of the statement of equity. Other than the change in presentation, the adoption of these changes had no material impact on our consolidated financial statements. The new guidance also required entities to present reclassification adjustments from accumulated other comprehensive income by component in both the statement in which net income is presented and the statement in which other comprehensive income is presented. However, in December 2011, the FASB issued guidance, which indefinitely defers the guidance related to the presentation of reclassification adjustments.

On January 1, 2012, we adopted changes issued by the FASB to provide a consistent definition of fair value and to ensure that the fair value measurement and disclosure requirements are similar between U.S. generally accepted accounting principles and International Financial Reporting Standards. The new guidance changed certain fair value measurement principles and enhanced the disclosure requirements particularly for Level 3 fair value measurements. The adoption of these changes did not have a material impact on our consolidated financial statements.

Impact of Recently Issued Accounting Standard – Not Yet Adopted

In July 2012, the FASB issued updated guidance on the periodic testing of indefinite-lived intangible assets for impairment. This guidance will allow companies to assess qualitative factors to determine if it is more-likely-than-not that indefinite-lived intangible assets might be impaired and whether it is necessary to perform a quantitative impairment test. This new guidance is effective for us beginning January 1, 2013, with early adoption permitted. We will adopt this standard and apply the provisions to our annual indefinite-lived intangible asset impairment testing in the 2012 fourth quarter. We do not expect the adoption will have a material effect on our consolidated financial statements.

3.  Acquisitions

2012 Acquisitions

On July 6, 2012, we acquired substantially all of the assets of Airport Metals (Australia) Pty Ltd, a subsidiary of Samuel Son & Co., Limited, through our newly-formed subsidiary Bralco Metals (Australia) Pty Ltd. Airport Metals (Australia), based in Melbourne, operates as a stocking distributor of aircraft materials and supplies. The addition of Airport Metals is our first entry into Australia and enhances our ability to service important aerospace customers in that area.

Effective April, 27, 2012, through our wholly-owned subsidiary Precision Strip, Inc., we acquired the assets of the Worthington Steel Vonore, Tennessee plant, a processing facility owned by Worthington Industries, Inc.  The Vonore plant operates as a Precision Strip, Inc. location which processes and delivers carbon steel, aluminum and stainless steel products on a “toll” basis, processing the metal for a fee without taking ownership of the metal.  The addition of the Vonore location to our existing footprint of facilities allows us to better service our customer base in an important geographic area of the country.

Effective April 3, 2012, we acquired all the outstanding limited liability company interests of National Specialty Alloys, LLC (“NSA”), a global specialty alloy processor and distributor of premium stainless steel and nickel alloy bars and shapes, headquartered in Houston, Texas.  In addition to enhancing our existing product offerings with the addition of specialty stainless steel and nickel products, NSA also expands and complements our growing exposure to the energy market.  NSA was founded in 1985 and has additional locations in Anaheim, California; Buford, Georgia and Tulsa, Oklahoma. Net sales of NSA during the period from April 3, 2012 through September 30, 2012 were approximately $47.4 million.

Effective February 1, 2012, through our wholly-owned subsidiary Diamond Manufacturing Company, we acquired McKey Perforating Co., Inc. (“McKey”), headquartered in New Berlin, Wisconsin and its subsidiary, McKey Perforated Products Co., Inc., located in Manchester, Tennessee. McKey was founded in 1867 and provides a full range of metal perforating and fabrication services to customers located primarily in the U.S.  McKey will be working closely with Diamond Manufacturing Company to leverage their combined expertise in the perforated metal market and further expand our presence within that market.  McKey had net sales of $14.5 million for the eight months ended September 30, 2012.

The combined transaction value of our 2012 acquisitions was $112.6 million, which included the assumption and repayment of $29.5 million of debt.  We funded these acquisitions with borrowings on our revolving credit facility.

2011 Acquisition

Effective August 1, 2011, we acquired all the outstanding capital securities of Continental Alloys & Services, Inc. (“Continental”), headquartered in Houston, Texas, and certain affiliated companies for a combined transaction value of approximately $440.8 million, which included the assumption and repayment of $104.7 million of debt. We funded this acquisition with borrowings on our revolving credit facility. Continental is a leading global materials management company focused on high-end steel and alloy pipe, tube and bar products and precision manufacturing of various tools designed for well completion programs of global energy service companies and has 12 locations in seven countries including Canada, Malaysia, Mexico, Singapore, the U.A.E., the United Kingdom, and the United States.  This acquisition aligns well with our diversification strategy by increasing our growing exposure to the energy market, including the addition of Oil Country Tubular Goods (“OCTG”) products, new processing capabilities, and entry into new international markets.  Continental and its affiliates had combined net sales of approximately $337.0 million for the nine months ended September 30, 2012.

Purchase Price Allocations

The purchase price allocations for the 2012 acquisitions are preliminary and are pending the completion of tangible and intangible asset valuations and various pre- and post-acquisition period income tax returns.

4.  Goodwill

The change in the carrying amount of goodwill for the nine months ended September 30, 2012 is as follows:

We had no accumulated impairment losses related to goodwill as of September 30, 2012.

5.  Intangible Assets, net

The following table summarizes our intangible assets, net:

Intangible assets recorded in connection with 2012 acquisitions were $41.0 million (see Note 3). We recognized amortization expense for intangible assets of $31.6 million and $25.9 million for the nine months ended September 30, 2012 and 2011, respectively. Other changes in intangible assets, net during the nine months ended September 30, 2012 are due to foreign currency translation gains of $4.6 million.

The following is a summary of estimated aggregated amortization expense for the remaining three months of 2012 and each of the succeeding five years:

6.  Income Taxes

Our effective income tax rates for the three-month periods ended September 30, 2012 and 2011 were 30.9% and 27.2%, respectively. Our effective income tax rates for the nine-month periods ended September 30, 2012 and 2011 were 32.9% and 32.2%, respectively. Permanent items that lowered our effective income tax rates from the federal statutory rate were not materially different in amounts during these periods and relate mainly to company-owned life insurance policies, domestic production activities deductions and foreign income levels that are taxed at lower rates. The increase in the 2012 three-month period effective income tax rate compared to the same period in 2011 is primarily attributable to changes in our blended state income tax rate based on shifts in our income, as well as settlement of various tax matters that had a favorable impact on our 2011 three-month period effective income tax rate.

7.  Debt

Debt consists of the following:

Unsecured Revolving Credit Facility

On July 26, 2011, we amended and restated the existing syndicated credit agreement to increase the borrowing limit from $1.1 billion to $1.5 billion, and to extend the maturity date of the credit facility for a five-year term to July 26, 2016.  The amended and restated revolving credit facility has 26 banks as lenders. Interest on borrowings from the amended and restated revolving credit facility is at variable rates based on LIBOR plus 1.50% or the bank prime rate plus 0.50% as of September 30, 2012.  The amended and restated revolving credit facility includes a commitment fee on the unused portion, at an annual rate of 0.25% as of September 30, 2012. The applicable margin over LIBOR rate and base rate borrowings, along with commitment fees, are subject to adjustment every quarter based on our leverage ratio, as defined.

Weighted average rates on borrowings outstanding on the revolving credit facility were 1.72% and 1.78% as of September 30, 2012 and December 31, 2011, respectively. As of September 30, 2012, we had $32.4 million of letters of credit outstanding under the revolving credit facility with availability to issue an additional $217.6 million of letters of credit.

Revolving Credit Facilities – Foreign Operations

Various other separate revolving credit facilities with a combined credit limit of approximately $20.8 million are in place for operations in Asia and Europe with combined outstanding balances of $13.5 million and $11.8 million as of September 30, 2012 and December 31, 2011, respectively.

Senior Unsecured Notes – Private Placements

We have $75.0 million of outstanding senior unsecured notes issued in private placements of debt as of September 30, 2012. The outstanding senior notes bear interest at a fixed rate of 5.35% and mature in July 2013.

Senior Unsecured Notes – Publicly Traded

On November 20, 2006, we entered into an Indenture (the “Indenture”), for the issuance of $600 million of unsecured debt securities. The total debt issued was comprised of two tranches, (a) $350 million aggregate principal amount of senior unsecured notes bearing interest at the rate of 6.20% per annum, maturing on November 15, 2016 and (b) $250 million aggregate principal amount of senior unsecured notes bearing interest at the rate of 6.85% per annum, maturing on November 15, 2036. The notes are senior unsecured obligations of Reliance and rank equally with all other existing and future unsecured and unsubordinated debt obligations of Reliance. The senior unsecured notes include provisions that, in the event of a change in control and a downgrade of our credit rating, require us to make an offer to repurchase the notes at a price equal to 101% of their principal amount plus accrued interest.

Covenants

The amended and restated revolving credit facility and the senior unsecured note agreements collectively require us to maintain a minimum net worth and interest coverage ratio and a maximum leverage ratio and include a change of control provision, among other things. Our interest coverage ratio for the twelve-month period ended September 30, 2012 was approximately 10.8 times compared to the debt covenant minimum requirement of 3.0 times (interest coverage ratio is calculated as net income attributable to Reliance plus interest expense and provision for income taxes and plus or minus any non-operating non-recurring loss or gain, respectively, divided by interest expense). Our leverage ratio as of September 30, 2012 calculated in accordance with the terms of the revolving credit facility was 28.7% compared to the financial covenant maximum amount of 60% (leverage ratio is calculated as total debt, inclusive of capital lease obligations and outstanding letters of credit, divided by Reliance shareholders’ equity plus total debt). The minimum net worth requirement as of September 30, 2012 was $1.09 billion compared to Reliance shareholders’ equity balance of $3.48 billion as of September 30, 2012.

Additionally, all of our wholly-owned domestic subsidiaries, which constitute the substantial majority of our subsidiaries, guarantee the borrowings under the revolving credit facility, the Indenture and the private placement notes. The subsidiary guarantors, together with Reliance, are required collectively to account for at least 80% of our consolidated EBITDA and 80% of consolidated tangible assets. Reliance and the subsidiary guarantors accounted for approximately 88% of our total consolidated EBITDA for the last twelve months and approximately 89% of total consolidated tangible assets as of September 30, 2012.

We were in compliance with all debt covenants as of September 30, 2012.

8.  Equity

Common Stock

During the nine months ended September 30, 2012, we issued 516,362 shares of common stock in connection with the exercise of stock options for total proceeds of approximately $20.6 million.

On May 16, 2012, our shareholders approved an amendment to our Restated Articles of Incorporation to increase the number of authorized shares of common stock from 100,000,000 to 200,000,000.

Share-Based Compensation

On May 16, 2012, pursuant to the May 2011 Directors Equity Plan, which has been approved by the shareholders, 16,842 shares of restricted stock were automatically granted to the non-employee members of the Board of Directors. The awards include dividend rights and vest immediately upon grant.  The recipients are restricted from trading the restricted stock for one year from date of grant.  The fair value of the restricted stock granted was $49.87 per share, determined based on the closing price of our common stock on the grant date.

On March 16, 2012, we granted 391,050 restricted stock units (“RSUs”) to key employees pursuant to the Amended and Restated Stock Option and Restricted Stock Plan. Each RSU has a service condition and cliff vests at December 31, 2014 and consists of the right to receive one share of our common stock and dividend equivalent rights, subject to forfeiture, equal to the accrued cash or stock dividends where the record date for such dividends is after the grant date but before the shares vest.  In addition to the service criteria, 138,700 of the 391,050 RSUs also have performance goals and vest only upon the satisfaction of the service and performance criteria.  The fair value of the restricted stock units granted was $57.42 per share, determined based on the closing price of our common stock on the grant date.

Share Repurchase Program

As of September 30, 2012, 7,883,033 shares of common stock remain authorized for repurchase under our stock repurchase program. No shares were repurchased in 2012 or 2011. Repurchased shares are redeemed and treated as authorized but unissued shares.

Accumulated Other Comprehensive Income (Loss)

Accumulated other comprehensive income (loss) included the following:

Foreign currency translation adjustments are not generally adjusted for income taxes as they relate to indefinite investments in foreign subsidiaries. Unrealized loss on investments and minimum pension liability are net of taxes of $0.1 million and $11.5 million, respectively, as of September 30, 2012 and December 31, 2011.

9.  Commitments and Contingencies

We are currently involved with certain environmental remediation projects related to activities at former manufacturing operations of our wholly-owned subsidiary Earle M. Jorgensen Company (“EMJ”) that were sold many years prior to our acquisition of EMJ in 2006. Although the potential cleanup costs could be significant, EMJ had insurance policies in place at the time they owned the manufacturing operations that are expected to cover the majority of the related costs. We do not expect that these obligations will have a material adverse impact on our financial position, results of operations or cash flows.

10.  Earnings Per Share

Basic earnings per share exclude any dilutive effects of options, restricted stock, RSUs, warrants and convertible securities. Diluted earnings per share are calculated including the dilutive effects of options, restricted stock, RSUs, warrants and convertible securities, if any.

The following table sets forth the computation of basic and diluted earnings per share:

11. Subsequent Events

Effective October 1, 2012, through our wholly-owned subsidiary Feralloy Corporation (“Feralloy”), we acquired all the outstanding capital stock of GH Metal Solutions, Inc. (formerly known as The Gas House, Inc.) (“GH”), a value added processor and fabricator of carbon steel products that will allow Feralloy to better serve the increasing demands of its diverse customer base.  GH, located in Fort Payne, Alabama, was founded in 1958 and has grown its processing equipment to include flat-bed lasers, tube lasers, torches, shears, automatic band saws, CNC press brakes, coil-fed and hand-fed stampers, robotic and manual welders, and a painting line. GH’s sales were approximately $44 million for the year ended December 31, 2011. GH will operate as a wholly-owned subsidiary of Feralloy.

Effective October 1, 2012, we acquired all the outstanding limited liability company interests of Sunbelt Steel Texas, LLC (“Sunbelt”), a value added distributor of special alloy steel bar and heavy-wall tubing products to the oil and gas industry. Sunbelt was founded in 1986 and is headquartered in Houston, Texas with an additional location in Lafayette, Louisiana. Sunbelt increases our growing exposure to the energy market in high end, niche products serving customers across multiple oil and gas well drilling types, including vertical, horizontal, directional, and deepwater drilling applications. Net sales of Sunbelt for the twelve months ended December 31, 2011 were approximately $48 million. Sunbelt will operate as a wholly-owned subsidiary of Reliance Steel & Aluminum Co.

We funded these acquisitions with borrowings on our revolving credit facility.

12. Condensed Consolidating Financial Statements

In November 2006, we issued senior unsecured notes in the aggregate principal amount of $600 million at fixed interest rates that are guaranteed by our wholly-owned domestic subsidiaries. The accompanying consolidating financial information has been prepared and presented pursuant to Rule 3-10 of SEC Regulation S-X “Financial Statements of Guarantors and Issuers of Guaranteed Securities Registered or Being Registered.” The guarantees are full and unconditional and joint and several obligations of each of the guarantor subsidiaries. There are no significant restrictions on our ability to obtain funds from any of the guarantor subsidiaries by dividends or loans. The supplemental consolidating financial information has been presented in lieu of separate financial statements of the guarantors as such separate financial statements are not considered meaningful.
