Put the numbers in context
At 36.53×, KLAC is 27.3% above its 10-observation annual average. A lower multiple can reflect a lower price, higher earnings, or weaker growth expectations—not necessarily a bargain.
The median of the 8 positive peer ratios above is 35.50×. Check growth, margins, debt, and earnings quality before interpreting the gap. A faster-growing business may justify a higher multiple.
One-off gains can temporarily lower P/E; unusual charges can raise it. Reported earnings and forward estimates answer different questions. Pair this view with return on equity and liquidity for a fuller picture.

Explore Wisesheets=WISE("KLAC", "PE Ratio", "LQ")Share price 149.79 ÷ EPS 4.1 = 36.53×. Data is supplied by Financial Modeling Prep through Wisesheets. Quote feed updated Nov 5, 2026; this is not a real-time trading quote.
Annual and quarterly P/E observations are provided separately from the current quote. Averages use the latest 3, 5, or 10 annual observations, excluding missing and nonpositive ratios. Pre-IPO observations are omitted. These are period-end observations, not daily averages.
The current quote feed does not specify the exact EPS filing-period end or whether EPS is basic or diluted. We do not label it as forward P/E. Peer ratios are explicitly trailing-12-month (TTM) values. Historical observations do not include independently verified price and EPS inputs. Sources may update on different schedules; rounded inputs can produce small calculation differences. Historical comparisons describe past pricing, not an estimate of fair value.
The essentials behind the numbers.
KLA Corporation's current P/E is 36.53× based on the quote data last updated Nov 5, 2026. It represents the share price divided by reported earnings per share. Prices and earnings may refresh on different schedules.
Annual P/E uses earnings for a completed fiscal year. Trailing-12-month (TTM) P/E uses the latest four quarters, while forward P/E uses forecast earnings. These are not interchangeable. This page labels peer ratios as TTM and shows dated annual or quarterly historical observations; it does not show forward estimates.
N/M means not meaningful: the feed has no positive P/E for that observation. Negative or zero earnings should not be ranked as a low positive valuation multiple. N/M observations are excluded from the averages shown above.
Divide the share price by earnings per share (EPS). For example, a share price of 100 and EPS of 5 gives a P/E of 20×. This page uses the price and EPS supplied together in the quote when both are positive.
Price timestamps, EPS definitions, share classes, adjustments, and fiscal periods can differ. A forward P/E also uses forecast earnings rather than reported earnings. Compare the inputs and as-of dates before comparing two displayed ratios.
Not necessarily. The average describes previous market pricing, not fair value. Changes in earnings quality, growth expectations, debt, accounting, and business risk can justify a different multiple today.
