USG Corporation Announces Launch of Senior Notes Offering

USG Corporation (NYSE: USG) today announced that it launched a private offering of $500 million aggregate principal amount of senior notes (the “New Notes”). The New Notes will be the unsecured obligations of USG. USG’s obligations under the New Notes will be guaranteed on a senior unsecured basis by certain of its domestic subsidiaries.

USG intends to use all or a portion of the net proceeds from the offering of New Notes to repurchase its outstanding 7.75% Senior Notes due 2018 (the “2018 Notes”) that are tendered pursuant to the cash tender offer that USG commenced today and to pay related costs and expenses. USG also intends to use any remaining net proceeds from the offering of New Notes and cash on hand to redeem any 2018 Notes that remain outstanding after completion of the tender offer.

The New Notes will be offered and sold only to persons reasonably believed to be qualified institutional buyers in accordance with Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and to non-U.S. persons in accordance with Regulation S under the Securities Act. The New Notes will not be registered under the Securities Act or state securities laws and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act and applicable state securities laws. This press release does not constitute an offer to sell or the solicitation of an offer to buy the New Notes or any other securities and shall not constitute an offer, solicitation or sale in any jurisdiction in which, or to any person to whom, such an offer, solicitation or sale is unlawful. Any offers of the New Notes will be made only by means of a private offering circular.
