Polen Focus Growth Strategy stated the following regarding CoStar Group, Inc. (NASDAQ:CSGP) in its Q1 2026 investor letter:
“CoStar Group, Inc. (NASDAQ:CSGP) has come under pressure from a combination of the negative AI narrative on software as well as its large investment in its Homes.com business that has driven company margins much lower than normal. We believe CoStar has deep domain expertise and data in commercial and residential real estate that is not replicable by large language models scraping the internet. And while we have some concern about the level of spend on Homes.com, we acknowledge that most of that capital has already been allocated and the revenue and profit expectations going forward from here look far better. In fact, we expect CoStar to be one of, if not the fastest growing company in the Portfolio over the next 3 to 5 years based on earnings per share. We added to our position here during the quarter.”
