Question 1

What is Williams Companies's P/E ratio?

Accepted Answer

Williams Companies (WMB) P/E ratio is 31.0× as of June 5, 2026. The ratio is calculated by dividing market capitalisation by trailing twelve-month earnings (net income), using USD-normalised financials (IAS 21 exchange-rate translation for non-USD reporters).

Question 2

How is the P/E ratio calculated?

Accepted Answer

P/E = Share Price ÷ Trailing Twelve-Month (TTM) Diluted EPS, or equivalently Market Capitalisation ÷ TTM Net Income. 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/E ratio?

Accepted Answer

The price-to-earnings (P/E) ratio, also called the earnings multiple, measures how much investors pay per dollar of a company's trailing twelve-month (TTM) earnings. It is calculated as share price ÷ TTM diluted EPS (equivalent to market capitalisation ÷ TTM net income). A higher P/E implies the market is pricing in stronger future earnings growth or lower risk; a lower P/E can signal slower expected growth, higher risk, or potential undervaluation.

Question 4

What is a good P/E ratio for Williams Companies?

Accepted Answer

There is no universal "good" P/E. As a rule of thumb, the S&P 500 has historically averaged a P/E in the mid-to-high teens; mature, slow-growth businesses commonly trade in the 10–18× range, while high-growth or asset-light companies often trade at 25–50×+. What matters is the comparison to sector peers and to the company's own historical range. For Williams Companies specifically, the relevant sector benchmark is the current sector median of 17.9×.

Question 5

Is Williams Companies's P/E ratio high or low?

Accepted Answer

Williams Companies's P/E ratio of 31.0× is above its own 5-year average of 23.3× and above the sector median of 17.9×. That places the current reading at the 76th 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 Williams Companies's historical P/E ratio range?

Accepted Answer

In the available daily series, Williams Companies (WMB) P/E ratio has ranged from a low of 4.7× in 2008 to a high of 1742.7× in 2017. The 5-year average is 23.3× and the 5-year median is 22.6×.

Question 7

What was Williams Companies's P/E ratio in 2025?

Accepted Answer

Williams Companies (WMB) P/E ratio at the end of 2025 was 28.1×. Annual values reflect the multiple on the last trading day of each calendar year, using the trailing twelve-month earnings figure available at that date.

Question 8

Why does Williams Companies's P/E ratio change over time?

Accepted Answer

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