On May 14, 2014, Signet UK Finance plc (the “Issuer”), a company organized under the laws of England and Wales and a wholly owned subsidiary of Signet Jewelers Limited (“Signet”), priced an offering of $400.0 million aggregate principal amount of the Issuer’s 4.700% Senior Notes due 2024 (the “Notes”). The Notes will be fully and unconditionally guaranteed on a senior unsecured basis by Signet and certain subsidiaries of Signet (collectively, the “Guarantors”). The Issuer and the Guarantors entered into an underwriting agreement, dated May 14, 2014 (the “Underwriting Agreement”), with J.P. Morgan Securities LLC, as representative of the several underwriters named therein (the “Underwriters”), in connection with the issuance and sale of the Notes and the related guarantees. The Issuer expects to issue the Notes on May 19, 2014.

The Underwriting Agreement contains customary representations, warranties, conditions to closing, indemnification and obligations of the parties. Signet has also agreed to indemnify the Underwriters against certain liabilities, including civil liabilities under the Securities Act of 1933, as amended, or to contribute to payments that the Underwriters may be required to make in respect of those liabilities.

The foregoing description of the Underwriting Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Underwriting Agreement, which is filed as Exhibit 1.1 hereto and incorporated herein by reference.

The offering of the Notes was registered under the Securities Act of 1933, as amended, pursuant to a registration statement on Form S-3 (File No. 333-195865).
