How KLA Went From Cheaper Than Teradyne To The Pricier Stock

In the world of chip equipment, paying more for slower growth seems like a mistake, but the market is making exactly that bet on one industry leader over its faster rival.

For investors in the semiconductor equipment space, KLA (KLAC) and Teradyne (TER) offer two distinct ways to own the industry's expansion. They are direct rivals, yet the market is pricing them differently. The central question for any KLA holder is this: what exactly is the premium valuation buying? The market currently charges 43.8 times operating profit for KLA, but 41.6 times for Teradyne, which is growing its revenue significantly faster.

This valuation gap is new. A year ago, the positions were flipped, with KLA trading at a discount to its peer. The market has since re-rated KLA higher, forcing the question of what has changed to justify a premium it did not previously command.

KLA's premium rests on its dominant market position and superior profitability.

The case for paying more for KLA starts with its financial quality. The company converts revenue into profit more efficiently than its peer, boasting a trailing operating margin of 41.7% versus 30.9% for Teradyne. More than a historical artifact, this profitability is a core part of the investment thesis, reflecting a deep moat in the specialized market for process control, the tools that inspect and measure chips during manufacturing.

Management is signaling confidence that its leadership will capture the current investment wave, driven by AI infrastructure. The company recently raised its expectation for the entire wafer equipment market to "the low $150 billion range in calendar 2026." KLA sees itself at the center of this growth, particularly in complex areas like advanced packaging, where it expects its process control systems revenue to grow in calendar 2026.

The key numbers side by side today:

OpInc = Operating Income, P/OpInc = Price To Operating Income Ratio

And the same comparison exactly a year ago, so you can see which way the mismatch has been moving:

OpInc = Operating Income

The cheaper peer is growing faster and signaling strength.

By paying KLA's premium, an investor gives up exposure to Teradyne's explosive top-line growth. Over the last twelve months, Teradyne's revenue grew 57.9%, far outpacing KLA's 13.4%. The company's momentum is carrying forward, making this more than a backward-looking number. At its latest earnings report, Teradyne raised its forward guidance, a clear signal of operational strength.

Beyond its cheaper multiple, Teradyne is a substantial business executing in a hot market. The company's latest quarterly revenue hit $1,329 million, driven primarily by its $1,122 million Semiconductor Test segment. Forgoing this combination of high growth and a lower valuation is the direct cost of owning KLA instead.

The choice hinges on profitability versus pace.

The decision between these two stocks boils down to a classic tradeoff. KLA offers leading profitability and a commanding market share in a critical niche. Teradyne offers a faster growth profile at a slightly lower price. The core debate is whether KLA's operational excellence can justify its slower pace and higher multiple, especially as it navigates what management calls a "challenging memory pricing environment."

Ultimately, an investor is choosing between paying for proven, high-margin dominance or betting on a faster-growing challenger to close the profitability gap. The most direct test of KLA's premium will be its ability to protect its margins amid rising costs. Management's guidance for the upcoming quarter's non-GAAP gross margin is a range of 61.5% to 63.5%. Where the actual result lands will be a key signal of whether the premium is money well spent.

What Would You Do With A Gain Like KLAC's 443%?

Picking the statistically better stock improves the odds; it does not change how much rides on one name. KLAC is up 443% over the past five years, and gains like that are exactly how one holding quietly becomes too large a share of a portfolio.
