    KLA (KLAC) Stock May Look Pricey Despite Easing Supply Constraints

    Simply Wall St·10/14/2026 09:32:53
    Listen to the news

    KLA has been on a powerful multi year run, and with the stock last closing at US$184.00 the key question for investors is whether that price still aligns with what its earnings support.

    • The share price has climbed 481.6% over 5 years. This puts a lot of focus on how firmly current earnings can underpin that kind of long term return record.
    • Recent commentary from Morgan Stanley suggests supply bottlenecks may ease and a stronger mix in leading logic tools could support margin expectations and the earnings power investors use in their valuation work.
    • The analysts covering KLA have run their own numbers. See what analysts think KLA's shares could be worth.

    The stock's next move may depend on whether KLA's current earnings are strong enough to justify today's market valuation.

    If you are weighing whether KLA's earnings justify its recent multi year run, it can help to compare that story with other 92 AI infrastructure stocks.

    Is KLA Getting Expensive on Earnings?

    The P/E ratio is a useful lens for KLA because earnings power is central to how investors frame established semiconductor equipment businesses. KLA trades on a P/E of 49.7x, slightly above both the semiconductor industry average of 48.6x and the peer group at 46.8x. On this basic comparison, buyers today are paying a richer price per dollar of current earnings than they would for many similar stocks in the sector.

    The fair value framework, which weights factors like profitability profile, size and sector risk, points to a lower P/E than where KLA is currently priced, so the stock screens as overvalued on this metric. Morgan Stanley’s view that easing supply constraints and a stronger leading logic mix could help margins explains some of that optimism, yet the valuation already builds in a strong earnings story. If you are comfortable with that implied earnings power, the present P/E can still make sense, but if you want a margin of safety on the multiple, it may look demanding. Explore the numbers behind KLA's P/E valuation.
