PRESS RELEASE

Washington, DC – August 8, 2022 – CoStar Group (NASDAQ: CSGP), a leading provider of online real estate marketplaces, information and analytics in the commercial and residential property markets, was awarded the prestigious title of Company of the Year at the 2022 Inman Innovator Awards.

The award, which was announced during Inman’s semiannual Connect event, recognizes CoStar Group’s commitment to innovation and transparency across the real estate industry. Throughout the company’s 35-year history, CoStar Group has driven a transformation of the industry, changing the way both consumers and professionals rent, lease, buy, and sell property by making accurate real estate information available to both sides of the transaction.

In 2022 alone, CoStar Group: launched Citysnap, a new search portal and app for the New York City market, in partnership with the Real Estate Board of New York (REBNY); introduced CoStar for Lenders, a groundbreaking live integration of data, models and analytics for commercial real estate lending; and continued its expansion into international markets in Europe with the acquisition of Business Immo, a leading real estate news service in France.

2022 also saw expansive growth in sales, earnings, and headcount for CoStar Group. In Q2, CoStar Group’s net income increased 37% year-over-year, and the company’s three flagship products (CoStar, Apartments.com, and LoopNet) all saw double digit sales increases.

In the months to come, CoStar Group will continue to invest in its residential portfolio, which includes Apartments.com, Homesnap.com, Homes.com, and Citysnap. In Q4, CoStar Group expects to relaunch Homes.com as a completely reimagined platform for homebuyers, with groundbreaking new features that will eliminate friction and frustration in the homebuying process.

“I am honored that CoStar Group has been recognized as a leader in innovation by Inman,” said Andrew Florance, Founder and Chief Executive Officer of CoStar Group. “This award is a reflection of the hard work and dedication of our employees. Thanks to this incredible team, CoStar Group is a leader in real estate data, analytics and online marketplaces, and our vision of bringing transparency to the real estate industry continues to resonate with consumers and industry professionals alike.”

Since 1998, the Inman Innovator Awards have honored companies, individuals and new technology that increases productivity, efficiency and transparency.
