Hudson Pacific Properties, Inc. Updates 2012 Outlook

Los Angeles, CA, May 18, 2012 – Hudson Pacific Properties, Inc. (the “Company”) (NYSE: HPP) today revised its full-year 2012 FFO guidance to a range of $0.83 to $0.87 per diluted share (excluding acquisition-related expenses), compared to the prior 2012 FFO guidance range of $1.00 to $1.04 per diluted share.

The Company recently completed the public offering of 13,225,000 shares of the Company's common stock for net proceeds of approximately $190.8 million (after underwriter discount). The Company intends to contribute the net proceeds from the offering to its operating partnership, which will subsequently use the net proceeds from the offering to repay the $10.0 million balance outstanding under its secured revolving credit facility, to finance the recently announced acquisitions of 901 Market Street and the Olympic Bundy properties and for general corporate purposes.

This guidance reflects the issuance of 13,225,000 shares of common stock, as described above, the repayment of the $10.0 million balance outstanding under the Company’s secured revolving credit facility, as well as the anticipated acquisitions of 901 Market Street and the Olympic Bundy properties, excluding acquisition-related expenses associated with such acquisitions. This guidance also reflects the Company’s FFO for the three months ended March 31, 2012 of $0.26 per diluted share outstanding over that three month period. The acquisitions of 901 Market Street and the Olympic Bundy properties are expected to contribute $0.4 million or $0.01 per diluted share to full-year 2012 FFO. Acquisition-related expenses for the 901 Market Street and the Olympic Bundy properties are estimated to be $2.6 million or ($0.06) per diluted share. The full-year 2012 FFO estimates reflect management’s view of current and future market conditions, including assumptions with respect to rental rates, occupancy levels and the earnings impact of events referenced in this release, but otherwise exclude any impact from future unannounced or speculative acquisitions, dispositions, debt financings or repayments, recapitalizations, capital market activity, or similar matters.
