Catalysts

About CoStar Group

Provides information, analytics, and online marketplace services in the United States, Canada, Europe, the Asia Pacific, and Latin America.

What are the underlying business or industry changes driving this perspective?

• Continued digitalization and demand for high-quality, data-driven real estate platforms are driving significant user growth, engagement, and record net new bookings across CoStar's core and expansion businesses, supporting ongoing double-digit revenue growth and higher recurring earnings.
  
• Market and regulatory trends continue to increase the need for transparency, fee disclosure, and real-time data, solidifying CoStar's role as a trusted industry standard and enabling sustainable pricing power, which should help further margin expansion.
  
• Aggressive investment in the Homes.com platform and rapid sales force expansion are enabling accelerated penetration in residential real estate, opening up a vast addressable market and creating meaningful opportunities for top-line growth and revenue diversification.
  
• Integration of AI-driven features, Matterport's 3D technology, and advanced analytics across platforms is increasing user engagement, enabling higher-value product offerings and upsells, and improving client retention-positioning the company for elevated margins and increased net income over time.
  
• CoStar's international expansion-through acquisitions (Domain in Australia), pan-European offerings, and market share gains-broadens its addressable market and underpins sustained long-term revenue growth and earnings scalability.

CoStar Group Future Earnings and Revenue Growth

Assumptions

How have these above catalysts been quantified?

• Analysts are assuming CoStar Group's revenue will grow by 11.2% annually over the next 3 years.
• Analysts assume that profit margins will increase from 2.1% today to 14.5% in 3 years time.
• Analysts expect earnings to reach $711.1 million (and earnings per share of $1.78) by about September 2029, up from $74.0 million today. However, there is some disagreement amongst the analysts with the more bullish ones expecting earnings as high as $860.0 million.
• In order for the above numbers to justify the price target of the analysts, the company would need to trade at a PE ratio of 23.7x on those 2029 earnings, down from 171.2x today. This future PE is greater than the current PE for the US Real Estate industry at 16.7x.
• Analysts expect the number of shares outstanding to decline by 4.39% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 8.5%, as per the Simply Wall St company report.

Risks

What could happen that would invalidate this narrative?

• The rapid expansion of Homes.com's sales force and aggressive investments in marketing and headcount carry a risk of increased operating expenses outpacing revenue growth if the residential business fails to achieve anticipated adoption and margin improvement, potentially compressing net margins and profitability over time.
  
• Matterport, while integrated into CoStar, is not profitable and its growth rate has slowed; if the B2B pivot, increased investment, and planned global salesforce expansion do not yield expected results, this could be a continued drag on consolidated earnings and limit EBITDA growth.
  
• Competitive threats, particularly from Zillow's aggressive tactics, ongoing lawsuits, antitrust scrutiny, and pricing actions, may increase customer acquisition costs or pressure pricing at Apartments.com, Homes.com, and other segments, creating potential headwinds for revenue and earnings if market share gains are challenged.
  
• The office segment of commercial real estate remains weak due to high vacancies and negative absorption, and while there has been an uptick in transaction volumes, a persistent shift towards remote/hybrid work or a macroeconomic downturn could structurally shrink the CRE market CoStar relies on, negatively impacting long-term revenue growth.
  
• A continued reliance on subscription models and large-scale annual contracts exposes CoStar to risk of elevated churn or lower renewal rates should major economic swings, increased competition, or changes in technology commoditize their data offerings, resulting in revenue volatility and potential earnings disruptions.

Valuation

How have all the factors above been brought together to estimate a fair value?

• The analysts have a consensus price target of $37.3 for CoStar Group based on their expectations of its future earnings growth, profit margins and other risk factors.
• However, there is a degree of disagreement amongst analysts, with the most bullish reporting a price target of $53.0, and the most bearish reporting a price target of just $25.0.
• In order for you to agree with the analysts, you'd need to believe that by 2029, revenues will be $4.9 billion, earnings will come to $711.1 million, and it would be trading on a PE ratio of 23.7x, assuming you use a discount rate of 8.5%.
• Given the current share price of $31.26, the analyst price target of $37.3 is 16.2% higher.
• We always encourage you to reach your own conclusions though. So sense check these analyst numbers against your own assumptions and expectations based on your understanding of the business and what you believe is probable.
