Issuance of $2,500,000,000 aggregate principal amount of secured and unsecured notes

Overview

On October 23, 2012, HCA Inc. (the “Issuer”), a wholly-owned subsidiary of HCA Holdings, Inc. (the “Parent Guarantor”), completed the public offering of (i) $1,250,000,000 aggregate principal amount of its 5.875% Senior Notes due 2023 (the “Unsecured Notes”), guaranteed on a senior unsecured basis by the Parent Guarantor and (ii) $1,250,000,000 aggregate principal amount of its 4.75% Senior Secured Notes due 2023 (the “Secured Notes” and, together with the Unsecured Notes, the “Notes”) guaranteed on a senior unsecured basis by the Parent Guarantor and on a senior secured basis by certain of the Parent Guarantor’s subsidiaries. The Notes have been registered under the Securities Act of 1933, as amended (the “Securities Act”), pursuant to the company’s shelf registration statement on Form S-3, filed on July 26, 2011, as amended by Post-Effective Amendments Nos. 1 and 2 thereto, filed on February 7, 2012 and February 27, 2012, respectively (File No. 333-175791) (the “Registration Statement”), as supplemented by the prospectus supplement dated October 16, 2012, previously filed with the Securities and Exchange Commission under the Securities Act.

On October 23, 2012, the Secured Notes were issued pursuant to a base indenture, dated as of August 1, 2012 (the “Base Indenture”), among the Issuer, the Parent Guarantor, Law Debenture Trust Company of New York, as trustee, (the “Trustee”) and Deutsche Bank Trust Company Americas, as registrar, paying agent and transfer agent (the “Registrar”), as amended and supplemented by the supplemental indenture, dated as of October 23, 2012, among the Issuer, the Parent Guarantor, the subsidiary guarantors named therein (the “Subsidiary Guarantors” and, together with the Parent Guarantor, the “Guarantors”), the Trustee and the Registrar (as supplemented, amended or modified from time to time, the “Secured Notes Indenture”).

Also on October 23, 2012, the Unsecured Notes were issued pursuant to the Base Indenture, as amended and supplemented by the supplemental indenture thereto, dated as of October 23, 2012, among the Issuer, the Parent Guarantor, the Trustee and the Registrar (as supplemented, amended or modified from time to time, the “Unsecured Notes Indenture” and, together with the Secured Notes Indenture, the “Indentures”).

Net proceeds from the offering of Notes, after deducting underwriter discounts and commissions and estimated offering expenses, are estimated to be approximately $2.469 billion. The Issuer intends to use the net proceeds from the offering of Notes for general corporate purposes, which may include the repayment of the Issuer’s existing term loan B-1 facility due November 2013 and the financing of a dividend to stockholders of HCA Holdings, Inc.
