Lam Research (LRCX) official guidance

And finally, we're expecting earnings per share of $2.15, ±$0.15, based on a share count of approximately 1.255 billion shares.

We do believe the tax rate will be in the mid-teens in the September quarter due to the increase in revenue in higher tax jurisdictions, primarily the United States, as we enter the new fiscal year.

And finally, we're expecting earnings per share of $2.15, ±$0.15, based on a share count of approximately 1.255 billion shares.

Now let's turn to our non-GAAP guidance for the September 2026 quarter. We're expecting revenue of $8.1 billion, ±$400 million, gross margin of 52%, ±1 percentage point, operating margins of 39.5%, ±1 percentage point.

Looking forward, we continue to expect capital expenditure to be in the 4%-5% of revenue range.

Finally, we're forecasting record earnings per share of $1.65, plus or minus $0.15, based on a share count of approximately 1.255 billion shares.

We continue to see the tax rate in the low- to mid-teens% for calendar year 2026.

I would encourage you to kind of keep it roughly in the levels that we just guided you to in June. This is going to kind of level out at where it's at, I think, for the rest of the year.

Let's turn to our non-GAAP guidance for the June 2026 quarter. We're expecting revenue of $6.6 billion ±$400 million. Gross margin of 50.5% ±1 percentage point.

We're forecasting operating margins of 36.5%, plus or minus one percentage point.

Let's turn to our non-GAAP guidance for the June 2026 quarter. We're expecting revenue of $6.6 billion ±$400 million.

Lam's advanced packaging revenue growth is expected to exceed 50% in calendar year 2026.

We expect that China revenue in the June quarter will decline from these levels.

Our progress can be seen in our strong March quarter results, our higher June quarter outlook, and our expectation that H2 calendar year revenues will exceed the H1.

In 2026, we see Lam's served available market, or SAM, percent of WFE expanding to slightly more than the mid-thirties % level, well on track toward our stated goal of high thirties % over the next few years.

In parallel, we expect growth in bit demand will drive greenfield capacity investment, especially considering that overall industry installed wafer capacity is expected to decline more than 20% from prior highs by the end of this year.

We now expect WFE of $140 billion with a bias to the upside as the industry continues to work through various constraints.

Where we believe demand to be, WFE is going to be nicely growing next year.
