Question 1

What is Merck & Co.'s P/S ratio?

Accepted Answer

Merck & Co. (MRK) P/S ratio is 4.6× as of June 5, 2026. The ratio is calculated by dividing market capitalisation by trailing twelve-month revenue, using USD-normalised financials (IAS 21 exchange-rate translation for non-USD reporters).

Question 2

How is the P/S ratio calculated?

Accepted Answer

P/S = Market Capitalisation ÷ Trailing Twelve-Month (TTM) Revenue, or equivalently Share Price ÷ TTM Revenue Per Share. 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 P/S ratio?

Accepted Answer

The price-to-sales (P/S) ratio compares a company's market capitalisation to its trailing twelve-month (TTM) revenue. It is calculated as market cap ÷ TTM revenue (equivalent to share price ÷ TTM revenue per share). Because the denominator (revenue) cannot be negative, P/S is widely used to value unprofitable or pre-profit companies and to make cross-sector comparisons.

Question 4

What is a good P/S ratio for Merck & Co.?

Accepted Answer

A "good" P/S depends heavily on profit margin and growth: software and other high-margin businesses often command 5–15× sales, while low-margin retailers and commodity producers typically trade below 1×. Compare against sector peers rather than absolute thresholds. For Merck & Co. specifically, the relevant sector benchmark is the current sector median of 3.5×.

Question 5

Is Merck & Co.'s P/S ratio high or low?

Accepted Answer

Merck & Co.'s P/S ratio of 4.6× is above its own 5-year average of 4.2× and above the sector median of 3.5×. That places the current reading at the 63th 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 Merck & Co.'s historical P/S ratio range?

Accepted Answer

In the available daily series, Merck & Co. (MRK) P/S ratio has ranged from a low of 2.0× in 2011 to a high of 5.6× in 2024. The 5-year average is 4.2× and the 5-year median is 4.2×.

Question 7

What was Merck & Co.'s P/S ratio in 2025?

Accepted Answer

Merck & Co. (MRK) P/S ratio at the end of 2025 was 4.0×. Annual values reflect the multiple on the last trading day of each calendar year, using the trailing twelve-month revenue figure available at that date.

Question 8

Why does Merck & Co.'s P/S ratio change over time?

Accepted Answer

Valuation multiples move with two inputs: the numerator (market capitalisation, which tracks the share price) and the denominator (revenue). 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.
