Lam Research reports its fiscal Q4 (June quarter) earnings next week on July 31, following a dismal market reaction to peer ASML’s report last week. Estimates are rather muted heading in to Lam’s report, though sentiment seems to have drifted sharply lower as semiconductor stocks declined 9% through the end of the week of July 19th.
Management has guided to $3.8 billion in revenue in Q4, approximately flat QoQ but up 18.5% YoY against weak comps from the rapid downturn in the memory market in 2023. Lam is expected to close the year with revenue and EPS both declining in the mid-teens YoY, with Q4’s strong YoY growth offsetting first half softness.
Revenue and EPS
Lam is expected to break its five-quarter streak of declining revenue on a YoY basis in Q4, with revenue growth accelerating more than 20 percentage points to ~18.5% YoY. EPS growth is expected to follow suit, with management guiding for operating margin to expand sequentially.
Analysts project Lam to report 19.4% revenue growth in the quarter to $3.83 billion, at the very high end of management’s guided range. This would represent a revenue acceleration of 2140 bp QoQ. Raymond James last month said that it expects “sector fundamentals to remain strong into 2025 due to secular growth from Gen AI, aggressive government subsidies around the world, multiple technology transitions, and intensifying competition among foundry suppliers.” Revenue is expected to increase sequentially by more than $200 million in each quarter in fiscal 2025.

- For Q4, management guided revenue at $3.8 billion, +/- $300 million, for a YoY increase of 18.5% and approximately flat QoQ growth.
- Management guided for GAAP EPS of $7.20, +/- $0.75 and adjusted EPS of $7.50, +/- $0.75, for adjusted EPS growth of 25.4% YoY. Analysts expect Lam to report $7.58 in adjusted EPS in Q4.
- For FY24, revenue is expected to be $14.87 billion, for a YoY decline of (14.7%).
- For FY24, adjusted EPS is expected to $29.75, down (12.8%) YoY.
- Current estimates for FY25 point to revenue of $17.66 billion, up 18.8% YoY, and adjusted EPS of $36.56, up 22.9% YoY.
As we had noted in April, Lam’s rebound through 2025 is primarily dependent on NAND recovering. Discussions around the incoming NAND rebound will be important, as well as discussions on DRAM given the surge in HBM we’ve seen to accompany rising GPU shipments.
Margins
Though management guided for gross margin to decline sequentially in Q4, there is some strength down the line, with operating margin expected to expand. China mix is also impacting margin positively, with Lam seeing gross margin as high as 48% compared to normalized levels of 46% when China’s revenue share is high.

- For Q4, management guided GAAP operating margin (above) at 46.7%, +/- 1%, implying a slight 80 bp QoQ contraction but a YoY expansion of 120 bp. Adjusted gross margin was guided at 47.5%, +/- 1%, a 120 bp QoQ contraction.
- GAAP operating margin was guided at 28.3%, +/- 1%, a 40 bp QoQ and 170 bp YoY expansion. Adjusted operating margin was guided at 29.5%, +/- 1%.
- Lam’s net margin has remained strong, with GAAP net margin at 25.4% to 25.5% in each quarter of FY24 so far.
Management shed some light on margins in the longer term as it begins to ramp up output in Malaysia, which is expected to be margin accretive due to cost advantages:
CEO Timothy Archer: “I think that we've built now a global footprint for our manufacturing and supply chain that makes us significantly more resilient. It allows us to scale much faster to the demand that we see coming in the future. And also improve our gross margin looking forward. And I think that as we move through these next cycles of industry upturn, companies and our output hitting new highs, the real power of that new manufacturing and supply chain infrastructure will really start to come to bear in our profitability.”And also improve our gross margin looking forward. And I think that as we move through these next cycles of industry upturn, companies and our output hitting new highs, the real power of that new manufacturing and supply chain infrastructure will really start to come to bear in our profitability.”
Cash and Debt
Cash flows have been strong for Lam despite the tough macro backdrop in the first half of the fiscal year.
- Operating cash flow was $1.38 billion in Q3, a 36.5% margin. YTD operating cash flow is $3.79 billion, down (6.6%) YoY, and for a margin of 34.3%. Operating cash flow for FY24 is projected to be $5.04 billion, implying $1.25 billion in OCF in Q4, a 11.3% YoY increase and representing a 32.9% margin.
- Free cash flow was $1.28 billion in Q3, a 33.7% margin. YTD free cash flow is $3.49 billion, down (3.9%) YoY, and for a margin of 31.6%.
- Cash and equivalents totaled $5.67 billion.
- Debt totaled $4.98 billion.
Key Metrics
For Lam’s upcoming Q4 report, memory sales mix will be closely watched, as non-volatile memory (NVM) recovers, a sign of the upcoming recovery in NAND.

Memory accounted for 44% of systems revenue in Q3, down from 48% in Q2, but up from 32% in the year ago quarter. DRAM accounted for 23%, with NVM accounting for 21%. NVM has recovered from 15% in Q2, but it remains far below its peak at the 40% range, seen during the prior cyclical peak in 2022.
In terms of geographic concentration, similar to its WFE peers, Lam has high exposure to China currently, with the nation accounting for more than 40% of revenue each quarter this year. While this has provided some margin tailwinds, it also presents a real headwind as export restriction tensions escalate.
It was discussed in-depth in Q3’s earnings call that China revenue is first-half weighted and revenue is expected to decline as the year progresses. Also, in the Q&A, it was brought up that management is possibly expecting more weakness as the year progresses due to customers being blacklisted – this was not confirmed directly but also was not denied.

Second to China in terms of revenue contribution is Korea, at 24%, followed by Japan and Taiwan at 9% each and the US at 6%. Korea is a key geographic market to track, given its significant global share in both DRAM and NAND. Over the past two quarters, Korea has increased its revenue share, rising to that 24% level from 19% in Q2 and 16% in Q1, hinting at NAND spending resuming and utilization ticking higher.
Noteworthy Points to Watch
As just mentioned, NAND’s recovery looks as if it is beginning to unfold with the first signs in NVM revenue share ticking higher. Management offered some perspective last quarter on what 2025 could look like for NAND, stating the following:
“I mean, clearly, we all know that the NAND spending has been incredibly weak for the last 12 to 18 months. And so we're in the very early stages of starting to see that recover. And I think if you look at what most of our — we rely on our customer commentary that they make publicly for a lot of this, but they talk about the fact that maybe 90% of the bits they're shipping are at the leading edge.
But when we look at the installed base of our systems, that was my comment. I believe that there is still going to be a large portion of the installed base that will move forward to the next technology nodes. It's the most efficient way for our customers to to do that is to upgrade what they already have. And I think you'll see that move forward and therefore, NAND WFE move up in '25. But because it comes through a large — to a large degree, through upgrades, Lam's capture rate of every dollar of WFE spend will be much higher than in a greenfield capacity added. So when I think about Lam's opportunity to outperform in 2025, in NAND, I think it is obviously with high confidence because of the type of spending we would expect to be seen in 2025. And in the other market segments, it's also pretty high because of the — as I mentioned, the technology inflections that are occurring […] And so I just feel like there are a number of growth drivers for the company besides the one that is the most obvious, which is a NAND recovery in 2025.”I believe that there is still going to be a large portion of the installed base that will move forward to the next technology nodes.

In the upcoming report, management’s commentary on the NAND recovery will be closely watched, as will NVM’s revenue share, given the emphasis placed on NAND as one of the primary growth drivers in 2025.
While this may seem a bit obvious, ultimately, Lam’s revenue guide for fiscal Q1 2025 will be a crucial data point for both Lam and the WFE manufacturers. ASML’s results, which sparked that sharp selloff across semis last week, saw strong net bookings but a Q3 revenue guide short of consensus, with the EUV maker expecting €6.7B to €7.3B in revenue versus the €7.5B consensus estimate. Analysts are expecting a strong report for Lam, with the consensus estimate at the high end of management’s guidance, and Q1’s estimate for $4.03 billion pointing to a 5.2%, or $200 million, sequential increase.
Valuation
Lam is trading above its median top line and bottom-line valuations, even with its steep sell-off after ASML’s earnings.
On the top-line, Lam trades at 8.9x trailing sales, and 7.1x forward sales with the rebound in sight. Looking back to 2021, Lam peaked at a trailing 7x sales multiple, so it’s currently trading above its peak multiples withheld historically as well as more than 40% higher than its 5-year average multiple of 5.2x for both trailing and forward sales.

Lam’s bottom line strength offers a bit more breathing more in the valuation, though it does remain stretched with a thin margin for error. Lam is trading at 35.3x trailing PE and 26.3x forward PE, again with EPS expected to rebound 23% YoY to $36.56. Again, while these multiples are elevated compared to Lam’s 5-year average in the 20x to 21x range, on a forward basis, Lam is trading at the same valuation as it entered 2024, around 26x, despite a nearly 30% YTD rally.

Conclusion
Lam’s fiscal Q4 report next week will hopefully show more growth and progress in the unfolding NAND rebound, which we had said we were a tad early to in April this year. We still see DRAM and HBM as a major growth opportunity in the AI semiconductor space, with Nvidia and AMD showing no signs of slowing in GPU development or revenue growth; however, NAND is expected to be a core growth driver for Lam moving through 2025.
Revenue growth is expected to be flat sequentially in Q4, before rising sequentially in each quarter of fiscal 2025, with earnings growth to follow. Cash flows also have remained quite strong despite the weak first half of the year. We’ll be keeping track of how this recovery will unfold next week, even if this report may not be enough to justify Lam’s elevated valuations in the near-term.
