Management Comments

• "The second quarter marked a profitability inflection point for CoStar Group as Adjusted EBITDA more than doubled year-over-year to $184 million."
• "We held operating cost growth to just 2%, and we delivered our 61st consecutive quarter of double-digit revenue growth."
• "For the first time, our residential segment turned Adjusted EBITDA positive – a $41 million improvement over the first quarter – and we expect to deliver the highest full-year Adjusted EBITDA in our company's history."
• "We continue to capture more of CoStar Group's $100 billion total addressable market through new product launches and geographic expansion."
• "Building on February's transformative launch of Homes.com Ai, we introduced Apartments.com Ai in June. Within weeks, Apartments.com Ai users completed more than half a million AI sessions – averaging 20 minutes per session, 2.8 times longer than non-AI users, viewing twice as many listings, with 3D tour usage up 224% and traffic-to-lead conversion up 256%."
• "Our product roadmap extends these AI capabilities across CoStar, LoopNet, and our international businesses."
• "This quarter we also delivered four major launches on our core CoStar platform – including CoStar Rent Benchmark, built from four million AI-abstracted lease agreements, and CoStar's market entry into France."
• "We accomplished all of this while reducing our projected expense base by roughly $100 million versus our original guidance, giving us a head start on our 2028 and 2030 Adjusted EBITDA targets."

Industry Context

StockSavvy.ai notes that CoStar Group's strong Q2 2026 performance, particularly its significant revenue growth and profitability improvements driven by AI integration and strategic investments, positions it favorably within the evolving proptech landscape. The company's ability to scale AI adoption across its platforms and expand internationally highlights its aggressive pursuit of market share in a competitive environment.

Comparison to Industry Standards

• CoStar Group's revenue growth of 18% in Q2 2026 significantly outpaces the average revenue growth for many established software and data analytics companies, which often see growth in the high single digits to low double digits.
• The 817% increase in net income and more than doubling of Adjusted EBITDA demonstrate a strong operational leverage and efficiency gains that are exceptional compared to industry peers, many of whom are focused on sustained profitability rather than rapid inflection points.
• The user engagement metrics for Apartments.com Ai (2.8x longer sessions, 2x more listings viewed, 224% increase in 3D tour usage, 256% traffic-to-lead conversion) suggest a superior product-market fit and technological advantage compared to competitors in the online real estate marketplace sector.
• CoStar's expansion into France and the development of products like CoStar Rent Benchmark, leveraging AI on millions of lease agreements, indicate a strategic approach to data aggregation and analysis that is more comprehensive than many regional or specialized data providers.
