Key Points
With investors overly focused on AI stocks they could be overlooking high-quality businesses like CoStar Group (CSGP). The stock has been punished on fears that AI models could completely distribute their business. This could be a throw the baby out with the bath water situation.
-
The stock has fallen sharply. Shares are down about 55% year-to-date and 69% from their 2025 high because investors fear AI disruption and question CoStar's heavy spending on residential real estate platforms like Homes.com and Apartments.com.
-
CoStar has a strong competitive moat. Its commercial real estate platform is built on a proprietary database collected and verified over 40 years, making it difficult for competitors or AI to replicate. The business has:
- 317,000 subscribers
- 92% customer renewal rate
- 15 consecutive years of double-digit revenue growth
-
Fundamentals remain strong. Despite the stock decline:
- Adjusted EBITDA grew 83% last year.
- Free cash flow turned positive.
- Analysts expect strong earnings growth through 2028.
-
AI may actually strengthen CoStar. AI becomes more valuable when paired with proprietary data, which CoStar owns. The company's AI-powered search helped Homes.com traffic increase 119%.
-
Management is confident. Founder and CEO Andrew Florance expects residential operations to reach breakeven by year-end and has personally purchased $5 million of CoStar stock in the open market.
Are you brave enough to catch the falling knife? As I free up cash from other investments I will probably consider dollar cost averaging into this company. I like the ability to build a position overtime and hold for many years.
To your success,
Thomas Moore
