Question 1

What is Quest Diagnostics's EV/EBITDA ratio?

Accepted Answer

Quest Diagnostics (DGX) EV/EBITDA ratio is 14.7× as of June 5, 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 Quest Diagnostics?

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 Quest Diagnostics specifically, the relevant sector benchmark is the current sector median of 15.0×.

Question 5

Is Quest Diagnostics's EV/EBITDA ratio high or low?

Accepted Answer

Quest Diagnostics's EV/EBITDA ratio of 14.7× is above its own 5-year average of 10.8× and below the sector median of 15.0×. That places the current reading at the 99th 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 Quest Diagnostics's historical EV/EBITDA ratio range?

Accepted Answer

In the available daily series, Quest Diagnostics (DGX) EV/EBITDA ratio has ranged from a low of 5.8× in 2022 to a high of 14.9× in 2026. The 5-year average is 10.8× and the 5-year median is 11.9×.

Question 7

What was Quest Diagnostics's EV/EBITDA ratio in 2025?

Accepted Answer

Quest Diagnostics (DGX) EV/EBITDA ratio at the end of 2025 was 12.7×. 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 Quest Diagnostics'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.
