Chambers Street Announces Intent to List on the New York Stock Exchange and Launch Tender Offer for up to $125 Million of its Common Shares

PRINCETON, N.J. – April 29, 2013 – Chambers Street Properties, a self-managed Maryland real estate investment trust (a “REIT”) that has invested approximately $3.2 billion in real estate and has more than 247 million common shares issued and outstanding, announced today its intention to list its common shares on the New York Stock Exchange (the “NYSE”) under the ticker symbol “CSG”. Chambers Street anticipates that its common shares will be listed on the NYSE on or about May 21, 2013, with completion of the listing subject to certain conditions. In addition, Chambers Street announced its intention to commence a modified “Dutch Auction” tender offer to purchase up to $125 million of its common shares. Chambers Street Properties also announced the approval of a quarterly distribution on its common shares for the third quarter ending September 30, 2013.

Listing

The board of trustees of Chambers Street Properties has determined that a listing of the Company’s common shares on the NYSE is in the best interest of the Company and its shareholders. Chambers Street currently owns or has majority interests in 129 properties, primarily industrial and office, located in 22 U.S. states, Germany and the United Kingdom. As of December 31, 2012, the portfolio was 98% leased to 272 tenants and diversified by location, industry, and lease expiration. In 2012, Chambers Street internalized its management structure, with no separate internalization fee paid, creating an integrated operating platform for managing its current portfolio, and that is scalable for the continued growth of the Company.

Chambers Street believes that a listing will enable it to continue to execute its asset management, portfolio growth, and capital strategies designed to maximize shareholder value. Publicly traded real estate companies have enjoyed strong returns in recent years, and companies that own net lease properties, similar to Chambers Street, are trading at attractive valuations. In addition, Chambers Street believes that a listing on the NYSE will provide access to additional potential investors as well as to a broader range of potential sources of capital.

Tender Offer

In conjunction with the listing, Chambers Street intends to commence a modified “Dutch Auction” tender offer (subject to all appropriate filings with the Securities and Exchange Commission) to purchase up to $125 million of its common shares. Under the terms of the proposed tender offer, the Company intends to select the lowest price, within a range of $10.10 per share and $10.60 per share, net to the tendering shareholder in cash, less any applicable withholding taxes and without interest, which would allow Chambers Street to purchase up to the full $125 million of its common shares. The Company expects to allow shareholders to tender all or a portion of their shares, but if the tender offer is oversubscribed, shares will be accepted on a prorated basis. Chambers Street intends to fund the tender offer with funds available under its unsecured revolving credit facility. Chambers Street expects to commence the proposed tender offer on or about May 21, 2013 in conjunction with the listing of its common shares on the NYSE. Wells Fargo Securities, LLC and Citigroup Global Markets Inc. will be the Dealer Managers for the proposed tender offer.

Important Notice

This Press Release is for informational purposes only and is not an offer to buy or the solicitation of an offer to sell any securities of the Company. The tender offer will be made only pursuant to an offer to purchase, letter of transmittal and related materials that the Company intends to distribute to its shareholders and file with the Securities and Exchange Commission (the “SEC”). The full details of the tender offer, including complete instructions on how to tender shares, will be included in the offer to purchase, the letter of transmittal and other related materials, which the Company will distribute to shareholders and file with the SEC upon commencement of the tender offer. Shareholders are urged to carefully read the offer to purchase, the letter of transmittal and other related materials when they become available because they will contain important information, including the terms and conditions of the tender offer.

Shareholders may obtain free copies of the offer to purchase, the letter of transmittal and other related materials that the Company files with the SEC at the SEC’s website at http://www.sec.gov or by calling the information agent for the contemplated tender offer, who will be identified in the materials filed with the SEC at the commencement of the tender offer.

Distributions

As a publicly traded company, the board of trustees has determined that the Company will pay a quarterly distribution to its shareholders, reflecting an annual payment of $0.50 per common share, beginning with the third quarter ending September 30, 2013. The Company anticipates that the third quarter distribution of $0.125 per common share will be paid on October 11, 2013 to all shareholders of record on September 26, 2013. Chambers Street believes this dividend level is competitive with dividend payments declared by other publicly traded real estate companies, and provides an appropriate level of retained capital to support the Company’s growth strategies.
