Question 1

What is CoStar Group's EV/EBITDA ratio?

Accepted Answer

CoStar Group (CSGP) EV/EBITDA ratio is 31.9× as of July 22, 2026. The ratio is calculated by dividing enterprise value by trailing twelve-month EBITDA, using USD-normalised financials (IAS 21 exchange-rate translation for non-USD reporters).

Question 2

How is the EV/EBITDA ratio calculated?

Accepted Answer

EV/EBITDA = Enterprise Value ÷ Trailing Twelve-Month (TTM) EBITDA, where Enterprise Value = Market Capitalisation + Total Debt − Cash & Short-Term Investments. All inputs are sourced from audited GAAP/IFRS filings and translated to USD using period-end exchange rates so the multiple is comparable across companies and currencies.

Question 3

What is the EV/EBITDA ratio?

Accepted Answer

The EV/EBITDA ratio (the enterprise multiple) compares enterprise value (EV) to trailing twelve-month (TTM) EBITDA. EV is calculated as market capitalisation + total debt − cash & short-term investments. Because EV/EBITDA is capital-structure-neutral and ignores non-cash depreciation and amortisation, it is the standard multiple used in M&A and for cross-company or cross-border comparisons. Note: this calculation uses a simplified EV (minority interest and preferred equity excluded due to data availability), consistent with most public financial-data providers.

Question 4

What is a good EV/EBITDA ratio for CoStar Group?

Accepted Answer

Mature, cash-generative businesses commonly trade in the 8–12× EV/EBITDA range; higher-growth, asset-light companies often trade at 15–25×+. EV/EBITDA is most useful for comparing companies with different capital structures (debt levels) or tax regimes. For CoStar Group specifically, the relevant sector benchmark is the current sector median of 15.8×.

Question 5

Is CoStar Group's EV/EBITDA ratio high or low?

Accepted Answer

CoStar Group's EV/EBITDA ratio of 31.9× is below its own 5-year average of 58.4× and above the sector median of 15.8×. That places the current reading at the 0th percentile of its 10-year history. A higher multiple usually reflects stronger expected growth, lower perceived risk, or higher returns on capital; a lower multiple reflects the opposite.

Question 6

What is CoStar Group's historical EV/EBITDA ratio range?

Accepted Answer

In the available daily series, CoStar Group (CSGP) EV/EBITDA ratio has ranged from a low of 6.5× in 2009 to a high of 202.0× in 2002. The 5-year average is 58.4× and the 5-year median is 53.3×.

Question 7

What was CoStar Group's EV/EBITDA ratio in 2025?

Accepted Answer

CoStar Group (CSGP) EV/EBITDA ratio at the end of 2025 was 87.5×. Annual values reflect the multiple on the last trading day of each calendar year, using the trailing twelve-month EBITDA figure available at that date.

Question 8

Why does CoStar Group's EV/EBITDA ratio change over time?

Accepted Answer

Valuation multiples move with two inputs: the numerator (enterprise value, which tracks share price plus net debt) and the denominator (EBITDA). Share-price changes — driven by interest rates, earnings expectations, risk appetite, and broader market sentiment — typically dominate short-term moves, while changes in the underlying fundamental drive the longer-term trend. As a result, the ratio can rise during stock-price rallies even if the business itself has not become more valuable, and fall during sell-offs even when fundamentals are improving.
