PRESS RELEASE

WASHINGTON, DC -- CoStar Group, Inc. (NASDAQ: CSGP), the leading provider of commercial real estate information, analytics and online marketplaces, announced today that it has completed the acquisition of Homes.com, previously announced on April 14, 2021, for $156 million in cash. The Federal Trade Commission cleared the transaction to close last week.

“The combination of Homes.com and Homesnap, which we acquired in December 2020, sets the stage for us to offer sellers, buyers, and real estate agents a better, more collaborative online home sale and purchase experience,” said Andrew C. Florance, Founder and Chief Executive Officer of CoStar Group. “Rather than building a business model based on creating friction to syphon off agent commissions, we plan to provide a next generation marketplace that connects listing and buyer agents to sellers and buyers without taking a cut of their commissions. We strongly believe that consumers are better served when they are matched to an agent for free, based upon the agent’s expertise, rather than based upon how much a random agent is willing to pay for a lead. Real estate agents are central to 90 percent of home sales. We respect that and want to help them strengthen their relationships with their clients, rather than trying to disrupt and monetize those relationships. It is time for just such an offering, and we believe we are uniquely positioned to provide it.”

With CoStar Group’s commitment to the principle that the leads generated by an agent’s listings belong to that agent, CoStar Group intends to discontinue Homes.com products and practices that are inconsistent with this principle.

CoStar Group has a track record of growing sector-leading site traffic with its online marketplaces such as Apartments.com, LoopNet, and many others. CoStar Group’s marketplaces generated more than one billion visits last year. With the acquisition of Homes.com, CoStar Group plans to similarly grow Homes.com site traffic by offering home buyers accurate, real-time information straight from the local MLS, supported by the best photography and multimedia content possible, all in a website that empowers homebuyers to collaborate with the agents they trust. CoStar Group’s hundreds of talented architectural photographers have brought millions of properties alive for millions of renters and buyers with the highest quality photographs, videos, aerial imagery, and 3D tours. Now this team is committed to providing an immersive and compelling presentation of residential properties on Homes.com.

Homesnap is the leading real estate productivity and marketing app and hundreds of thousands of the most productive real estate agents in the country rely on it to manage their businesses. CoStar Group intends to fully integrate Homesnap and Homes.com, with Homesnap at one end as the agent’s professional tool and Homes.com on the other side as the home buyer’s portal. Once integrated, agents will have instant access to manage their listings on Homes.com, view and respond to inquiries, collaborate with clients, and provision and monitor sophisticated digital marketing campaigns. We believe this direct connection between agents and a consumer portal is unique in the industry.

Homes.com has one of the largest real estate portal sales forces and CoStar Group intends to leverage that sales force to sell the Homesnap product with the goal of expanding Homesnap’s reach to hundreds of thousands of additional real estate agents. CoStar Group expects Homes.com to contribute approximately $10 million in incremental revenue and approximately $15 million in negative adjusted EBITDA in 2021, which includes the negative impact of the planned business model transition on existing Homes.com product revenue.
