(NYSE: DLR) announced today that its wholly owned subsidiary, Digital Delta Holdings, LLC, priced a private placement of $500 million aggregate principal amount of 3.400% Notes due 2020 (the “2020 notes”) and $450 million aggregate principal amount of 4.750% Notes due 2025 (the “2025 notes”, and together with the 2020 notes, the “notes”) at 99.777% and 100% of the principal amount of the 2020 notes and 2025 notes, respectively. The notes will be fully and unconditionally guaranteed by Digital Realty Trust, Inc. and its operating partnership subsidiary, Digital Realty Trust, L.P.

The net proceeds from the offering are expected to be used to fund a portion of the aggregate purchase price for the previously announced pending acquisition of Telx Holdings, Inc.

Following the acquisition of Telx Holdings, Inc., Digital Delta Holdings, LLC will be merged with and into Digital Realty Trust, L.P., with Digital Realty Trust, L.P. surviving the merger and assuming Digital Delta Holdings, LLC’s obligations under the notes by operation of law.

The notes were offered and sold to qualified institutional buyers in the United States pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and outside the United States pursuant to Regulation S under the Securities Act.

The notes have not been registered under the Securities Act or any 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 laws.

This press release shall not constitute an offer to sell or a solicitation of an offer to purchase the notes or any other securities and shall not constitute an offer, solicitation or sale in any state or jurisdiction in which such an offer, solicitation or sale would be unlawful.
