Hudson Pacific Properties Sells

San Mateo Office Campus for $210 Million

Los Angeles, July 30, 2018-Hudson Pacific Properties, Inc. (NYSE: HPP) today announced the sale of the remaining six buildings of Peninsula Office Park in San Mateo for $210 million before credits, prorations and closing costs. The all-cash transaction represents a 5.1% premium to the company’s GAAP basis and a 15.4% premium to the allocated purchase price.

“The sale of Peninsula Office Park’s remaining six buildings exemplifies our approach to recycling capital to further focus on strategic holdings in our core markets,” said Victor Coleman, Hudson Pacific’s Chairman and CEO. “We will continue to enhance our already high-caliber office portfolio by capitalizing on favorable market conditions, and we are always looking for creative ways to maximize value for our shareholders. We intend to re-deploy proceeds from this successful two-part sale to fund prudent, long-term growth, including the acquisition of higher-yielding opportunities.”

Buildings 1-5 and 7 of Peninsula Office Park total 447,739 square feet, and, as of the end of the first quarter of this year, were 83% occupied. Hudson Pacific sold the fully vacant 63,050-square-foot Building 6 in January of this year for a total of $22.5 million before prorations, credits and closing costs.

Net proceeds from the sale were used to repay amounts outstanding on the company’s revolving credit facility, with the remainder held for general corporate purposes.

Additional details about the sale of Peninsula Office Park, including its impact on full-year 2018 FFO guidance, will be provided in connection with the company’s second quarter earnings call on August 1, 2018.
