CommonWealth REIT Makes Investor Presentation Available, Offers Added Detail Related to Strategic Plan

CommonWealth REIT

today made available an investor presentation detailing the Company's strategic plan and responding to inaccurate assertions by Corvex Management LP ("Corvex") and Related Fund Management, LLC ("Related" and together with Corvex, "Corvex/Related"). The presentation is available on the Company's web site at www.cwhreit.com and will be filed with the Securities and Exchange Commission (“SEC”) later today. The presentation includes information regarding CWH and its high-quality assets, as well as the Company's governance, fee structure, and strategy to continue creating value for shareholders. In particular, the presentation provides details of the Company's track record of success and the ongoing implementation of its strategic plan. Since 2008, CWH has been repositioning its portfolio by selling suburban office and industrial properties and re-investing proceeds into high quality urban, or central business district (“CBD”), office properties with strong long term growth prospects. CWH is making progress in executing its strategic plan: * Since January 1, 2008, CWH has increased its portfolio concentration of CBD office properties from approximately 29% (based on Q4 2007 wholly owned property level net operating income, or “NOI”) to approximately 56% (based on Q4 2012 NOI). * Acquired $3.7 billion of primarily Class A CBD office properties, principally from distressed sellers. * Sold $1.5 billion of primarily suburban office properties for significant gains. * The Company is currently marketing for sale 94 properties with low occupancy and negative cashflow. * 18 of these 94 properties have been sold to date. * CWH has unlocked value for the Company by raising equity through "carve-out" IPOs for Government Properties Income Trust

and Select Income REIT

at higher multiples than issuing equity at CWH. * Received $650 million of combined proceeds from “carve-out” IPOs of GOV and SIR. * Recently, CWH sold its remaining equity position in GOV for $240.1 million, recognizing a gain of $66.3 million.
