On September 15, 2017, MRC Global Inc. (the “Company”) issued a press release announcing its receipt of preliminary commitments for a previously announced $400 million term loan facility (“Term Loan B”).

Although the arrangers of the Term Loan B have reported receipt of preliminary commitments from interested lenders and allocation of participations in the Term Loan B based on these commitments, the closing and funding of the Term Loan B will be subject to the fulfillment of various conditions, including entering into definitive documentation with the lenders, delivery of customary closing documents and legal opinions and delivery of collateral satisfactory to the lenders.

Forward-Looking Statements

This news release contains forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. Words such as “will,” “expects”, “would” and similar expressions are intended to identify forward-looking statements.

Despite the Company’s expectations of entering into a new term loan, the terms and pricing of a term loan, the amendment of its global ABL facility amendment, the terms of the amendment and the use of proceeds to refinance its existing term loan are only the Company’s expectations regarding these actions. Whether the Company is actually successful in obtaining such a term loan and global ABL amendment on expected terms and conditions with expected uses of proceeds is dependent on a number of factors, including (among others) debt market conditions, reaching final agreement on the definitive documentation with lenders and the Company’s financial condition, results and future prospects, which, in turn are dependent on factors, including (among others) those that impact the Company’s business. These factors are more fully set out in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 that the Company has filed with the U.S. Securities and Exchange Commission, which can be viewed at www.mrcglobal.com.
