KLA (KLAC) official guidance

EPS guidance is based on a fully diluted share count of approximately 1.306 billion shares.

Planning tax rate is 14.5%.

In the December quarter, non-GAAP diluted EPS is expected to be $1.44 plus or minus $0.11, and GAAP diluted EPS is expected to be $1.41 plus or minus $0.11.

In the December quarter, non-GAAP diluted EPS is expected to be $1.44 plus or minus $0.11, and GAAP diluted EPS is expected to be $1.41 plus or minus $0.11.

Gross margin for the December quarter is forecasted to be 62.5%, plus or minus one percentage point.

Operating expenses are forecasted to be approximately $710 million in the December quarter.

As a reminder, our business model is designed to deliver 40%-50% incremental operating margin leverage on revenue growth over the long run.

Other model assumptions include other income and expense, net of approximately $25 million expense for the December quarter, and we expect it to remain at approximately this quarterly level.

For calendar 2026, advanced packaging process control systems revenue remains on track to hit approximately $1.1 billion or more than 70% year-over-year growth, nearly twice the growth rate of the advanced packaging market.

This is resulting in growth in the second half of calendar year 2026 over the first half of approximately 25% and positions the company for continued sequential growth into calendar 2027.

I think in 2027, that will continue. I expect China will likely grow a little bit, but not at the same rate as the growth in wafer equipment outside of China. So we are probably operating somewhere, I would say, in the low 20th percentile in 2027.

I thought that China, as a percent of the total, would be in the high 20, 28 percentile. So we will call it somewhere between 27% and 29%, and I still believe that therefore implies that the fourth quarter is in that similar range, given what we have done in the previous three quarters.

Within memory, DRAM is expected to account for approximately 84%, with NAND representing the remaining 16%.

Foundry logic revenue for semiconductor customers is forecasted to be approximately 60%, and memory is expected to be about 40% of Semiconductor Process Control Systems revenue to semiconductor customers.

In 2027, we'd expect overall memory to be about 60% of the business, and in an environment where, to Rick's point, we feel pretty confident about our ability to perform pretty well relative to the overall market.

At Investor Day, we talked about $220 billion plus or minus $20 billion view.

We are therefore raising our expectation for the wafer equipment market, including advanced packaging, to approximately the mid $150 billion range in calendar 2026.

we currently expect the wafer equipment market to exceed $200 billion in calendar 2027.
