Vulcan Value Partners stated the following regarding CoStar Group, Inc. (NASDAQ:CSGP) in its Q1 2026 investor letter:
“CoStar Group, Inc. (NASDAQ:CSGP) is a premier information services provider to the commercial and residential real estate industries. Its core businesses are dominant, have high barriers to entry, produce copious amounts of free cash flow, and historically have grown at a double digit rate. We bought CoStar because of these businesses. Several years ago, after we purchased CoStar, the company bought Homes.com. They have taken virtually all of the company’s free cash flow and reinvested it into Homes.com in an attempt to disrupt the residential brokerage portal industry. Stated simply, it has not worked and the company continues to reinvest virtually all of its free cash flow into Homes.com, which management now says will not be profitable until 2030, 8 years after it launched the business. We no longer qualify CoStar Group for investment because of poor capital allocation. Following our discipline we sold it to reallocate capital into more discounted companies with better management teams.”
