Question 1

What is ON Semiconductor's P/B ratio?

Accepted Answer

ON Semiconductor (ON) P/B ratio is 6.3× as of June 5, 2026. The ratio is calculated by dividing market capitalisation by book value of equity, using USD-normalised financials (IAS 21 exchange-rate translation for non-USD reporters).

Question 2

How is the P/B ratio calculated?

Accepted Answer

P/B = Market Capitalisation ÷ Book Value of Equity (most recent quarterly shareholders' equity), or equivalently Share Price ÷ Book Value 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/B ratio?

Accepted Answer

The price-to-book (P/B) ratio compares a company's market capitalisation to its book value of equity (total shareholders' equity) on the most recent quarterly balance sheet. It is calculated as market cap ÷ book value of equity (equivalent to share price ÷ book value per share). A P/B below 1× implies the market values the business below its accounting net worth; values well above 1× reflect intangible assets, brand value, or a high return on equity.

Question 4

What is a good P/B ratio for ON Semiconductor?

Accepted Answer

A "good" P/B depends on the business model. Banks, insurers, and other capital-heavy financials typically trade near 1×; asset-light technology and consumer-brand companies can sustainably trade at 5×+ because much of their value is intangible. P/B is most informative when paired with return on equity (ROE). For ON Semiconductor specifically, the relevant sector benchmark is the current sector median of 6.0×.

Question 5

Is ON Semiconductor's P/B ratio high or low?

Accepted Answer

ON Semiconductor's P/B ratio of 6.3× is above its own 5-year average of 4.1× and above the sector median of 6.0×. That places the current reading at the 92th 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 ON Semiconductor's historical P/B ratio range?

Accepted Answer

In the available daily series, ON Semiconductor (ON) P/B ratio has ranged from a low of 1.4× in 2020 to a high of 172.7× in 2007. The 5-year average is 4.1× and the 5-year median is 4.1×.

Question 7

What was ON Semiconductor's P/B ratio in 2025?

Accepted Answer

ON Semiconductor (ON) P/B ratio at the end of 2025 was 2.8×. Annual values reflect the multiple on the last trading day of each calendar year, using the trailing twelve-month book value figure available at that date.

Question 8

Why does ON Semiconductor's P/B ratio change over time?

Accepted Answer

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