Global Real Estate Services Leader Expands Access to Commercial Real Estate's Most Comprehensive Database

CoStar Group, Inc. (NASDAQ: CSGP) announced today that it has concluded a national licensing renewal agreement with global real estate leader Cushman & Wakefield.

"We're very pleased to continue our long-standing association with Cushman & Wakefield, one of the most respected and recognized names in commercial real estate," stated CoStar Group CEO Andrew C. Florance. "Our research team curates and certifies information on approximately $1 trillion of potential real estate transactions, tracking billions of square feet of office, retail and industrial space. The information, marketing and analytic tools we provide result in significant productivity gains for subscribers and help facilitate the vast majority of commercial real estate transactions in the United States. We welcome this opportunity to continue providing our information services to Cushman & Wakefield under this expanded agreement."

"Now, more than ever, our clients rely on deep insights to make decisions about their business," said Joseph Stettinius, Chief Executive, Americas Brokerage and Capital Markets for Cushman & Wakefield.
