NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

September 30, 2019

Note 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 (“U.S. GAAP”) 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. GAAP for complete financial statements. In the opinion of management, our financial statements reflect all adjustments, which are of a normal recurring nature, necessary for presentation of financial statements for interim periods in accordance with U.S. GAAP. The results of operations for the nine months ended September 30, 2019 are not necessarily indicative of the results for the full year ending December 31, 2019. These financial statements should be read in conjunction with the consolidated financial statements and footnotes thereto for the year ended December 31, 2018, included in the Reliance Steel & Aluminum Co. (“Reliance,” the “Company,” “we,” “our” or “us”) Annual Report on Form 10-K.

The preparation of financial statements in conformity with U.S. GAAP 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. All significant intercompany accounts and transactions have been eliminated. 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.

Leases—In February 2016, the Financial Accounting Standards Board (“FASB”) issued accounting changes that require lessees to recognize most long-term leases on the balance sheet through the recognition of a right-of-use asset and a lease liability using a modified retrospective transition method and provide enhanced disclosures. In July 2018, the FASB issued an update to these accounting changes providing an additional, optional transition method that allows lessees the option to initially apply the new accounting changes at the adoption date while continuing to present all prior periods under previous lease accounting guidance.

We adopted the new standard on January 1, 2019 using the optional transition method and available practical expedients. The practical expedients allow us, among other things, to carry forward our assessment of lease classification and remaining lease terms under the previous lease accounting guidance. Our adoption of the new lease standard resulted in the recognition of $186.3 million of operating lease right-of-use assets and $187.1 million of operating lease liabilities but did not have a material impact on our consolidated statements of income, equity or cash flows. For further discussion of our leases, see Note 7 – “Leases.”

Unsecured Credit Facility

On September 30, 2016, we entered into a $2.1 billion unsecured five-year credit agreement (“Credit Agreement”) comprised of a $1.5 billion unsecured revolving credit facility and a $600.0 million unsecured term loan, with an option to increase the revolving credit facility up to an additional $500.0 million at our request, subject to approval of the lenders and certain other customary conditions. The term loan due September 30, 2021 amortizes in quarterly installments, with an annual amortization of 10% until June 2021, with the balance to be paid at maturity. Interest on borrowings under the Credit Agreement at September 30, 2019 was at variable rates based on LIBOR plus 1.00% or the bank prime rate and we pay a commitment fee at an annual rate of 0.125% on the unused portion of the revolving credit facility. During the third quarter of 2019, applicable margins were lowered by 25 basis points and our commitment fees were reduced per the terms of the Credit Agreement as a result of a decrease in our calculated leverage ratio. The applicable margins over LIBOR and base rate borrowings, along with commitment fees, are subject to adjustment every quarter based on our leverage ratio, as defined in the Credit Agreement. All borrowings under the Credit Agreement may be prepaid without penalty.

Weighted average interest rates on borrowings outstanding on the revolving credit facility were 3.20% and 3.86% as of September 30, 2019 and December 31, 2018, respectively. Weighted average interest rates on borrowings outstanding on the term loan were 3.04% and 3.77% as of September 30, 2019 and December 31, 2018, respectively. As of September 30, 2019, we had $408.0 million of outstanding borrowings, $40.6 million of letters of credit issued and $1.05 billion available for borrowing on the revolving credit facility.

Senior Unsecured Notes

On November 20, 2006, we entered into an indenture (the “2006 Indenture”) for the issuance of $600.0 million of unsecured debt securities. The total debt issued was comprised of two tranches, (a) $350.0 million aggregate principal amount of senior unsecured notes bearing interest at the rate of 6.20% per annum, which matured and were repaid on November 15, 2016 and (b) $250.0 million aggregate principal amount of senior unsecured notes bearing interest at the rate of 6.85% per annum, maturing on November 15, 2036.

On April 12, 2013, we entered into an indenture (the “2013 Indenture” and, together with the 2006 Indenture, the “Indentures”) for the issuance of $500.0 million aggregate principal amount of senior unsecured notes at the rate of 4.50% per annum, maturing on April 15, 2023.

Under the Indentures, the notes are senior unsecured obligations and rank equally in right of payment with all of our existing and future unsecured and unsubordinated obligations. If we experience a change in control accompanied by a downgrade in our credit rating, we will be required to make an offer to repurchase the notes at a price equal to 101% of their principal amount plus accrued and unpaid interest.

Other Notes and Revolving Credit Facilities

Revolving credit facilities with a combined credit limit of $9.8 million are in place for operations in Asia with combined outstanding balances of $4.6 million and $4.7 million as of September 30, 2019 and December 31, 2018, respectively.

Various industrial revenue bonds had combined outstanding balances of $9.2 million as of September 30, 2019 and $9.5 million as of December 31, 2018, and have maturities through 2027.

Covenants

The Credit Agreement and the Indentures include customary representations, warranties, covenants and events of default provisions. The covenants under the Credit Agreement include, among other things, two financial maintenance covenants that require us to comply with a minimum interest coverage ratio and a maximum leverage ratio. We were in compliance with all financial covenants in our Credit Agreement at September 30, 2019.

Note 7. Leases

Our metals service center leases are comprised of processing and distribution facilities, equipment, trucks and trailers, ground leases and other leased spaces, such as depots, sales offices and storage. We also lease various office buildings, including our corporate headquarters in Los Angeles, California. Our leases of facilities and other spaces expire at various times through 2031 and our ground leases expire at various times through 2068. Nearly all of our leases are operating leases. Information regarding the insignificant amount of finance leases we have is not meaningful to an understanding of our lease obligations.

Dividends

On October 22, 2019, our Board of Directors declared the 2019 fourth quarter cash dividend of $0.55 per share of common stock, payable on December 6, 2019 to stockholders of record as of November 15, 2019.

During the three months ended September 30, 2019 and 2018, we declared and paid quarterly dividends of $0.55 and $0.50 per share, or $36.7 million and $35.9 million in total, respectively. During the nine months ended September 30, 2019 and 2018, we declared and paid quarterly dividends of $1.65 and $1.50 per share, or $110.6 million and $108.5 million in total, respectively. In addition, we paid $2.7 million and $2.0 million in dividend equivalents with respect to vested restricted stock units (“RSUs”) during the nine months ended September 30, 2019 and 2018, respectively.

Stock-Based Compensation

We make annual grants of long-term incentive awards to officers and key employees in the forms of service-based and performance-based RSUs that have approximately 3-year vesting periods. The performance-based RSU awards are subject to both service and performance goal criteria. We also make annual grants of stock to the non-employee members of the Board of Directors that vest immediately upon grant. The fair value of the RSUs and stock grants is determined based on the closing stock price of our common stock on the grant date.

In the nine months ended September 30, 2019 and 2018, we made payments of $9.6 million and $5.5 million, respectively, to tax authorities on our employees’ behalf for shares withheld related to net share settlements. These payments are reflected in the Stock-based compensation, net caption of our consolidated statements of equity.

A summary of the status of our unvested service-based and performance-based RSUs as of September 30, 2019 and changes during the nine-month period then ended is as follows:

Share Repurchase Plan

On October 23, 2018, our Board of Directors amended our share repurchase plan, increasing the total authorized number of shares available to be repurchased by 5.0 million and extending the duration of the plan through December 31, 2021. As of September 30, 2019, we had authorization under the plan to repurchase approximately 6.4 million shares, or about 10% of our current outstanding shares. We repurchase shares through open market purchases under plans complying with Rule 10b5-1 and Rule 10b-18 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Repurchased and subsequently retired shares are restored to the status of authorized but unissued shares. Our share repurchases were $50.0 million in the nine months ended September 30, 2019 and $130.7 million, including $0.6 million pending settlement, in the nine months ended September 30, 2018.

Pension and postretirement benefit adjustments are net of taxes of $6.5 million as of September 30, 2019 and December 31, 2018. Income tax effects are released from accumulated other comprehensive loss as defined benefit plan and supplemental executive retirement plan obligations are settled.

Environmental Contingencies

We are currently involved with an environmental remediation project related to activities at former manufacturing operations of Earle M. Jorgensen Company (“EMJ”), our wholly owned subsidiary, that were sold many years prior to our acquisition of EMJ in 2006. Although the potential cleanup costs could be significant, EMJ maintained insurance policies during the time it owned the manufacturing operations that have covered costs incurred to date, and are expected to continue to cover the majority of the related costs. We do not expect that this obligation will have a material adverse impact on our consolidated financial position, results of operations or cash flows.

Legal Matters

From time to time, we are named as a defendant in legal actions. Generally, these actions arise in the ordinary course of business. We are not currently a party to any pending legal proceedings other than routine litigation incidental to the business. We expect that these matters will be resolved without having a material adverse impact on our consolidated financial position, results of operations or cash flows. We maintain general liability insurance against risks arising in the ordinary course of business.
