Executive Summary
CoStar Group operates a highly profitable core commercial real estate (CRE) data business, often called the 'Bloomberg of CRE', with a deep competitive moat built over 37 years and 59 consecutive quarters of double-digit revenue growth.
The company has invested over $5 billion into its residential platform, Homes.com, to compete with Zillow, causing operating profits to plummet and the stock to significantly underperform the S&P 500 over the last five years.
This aggressive spending has attracted activist investor Third Point, which is calling for a board overhaul and a pullback on the residential investment, creating a classic battleground scenario for investors.
Despite the controversy, the core business remains strong with nearly 50% profit margins, and there are growth opportunities in underpenetrated assets like LoopNet, presenting a potential value opportunity if management can execute or rationalize its spending.
