Lam Research designs, makes, sells and services the equipment that processes silicon wafers, concentrated in deposition, etch and clean. Its customers are memory makers, foundries and integrated device manufacturers. Revenue splits two ways: new systems, recognised on shipment or delivery, and the Customer Support Business Group — spares, upgrades, services and the non-leading-edge Reliant line — where services are recognised over time.
The business in one page
There is one reportable segment, and the only revenue breakdown in absolute amounts is systems against customer support. By market served the filing gives percentages of equipment and upgrade revenue: foundry 45%, memory 42%, logic and integrated device makers 13%. China is 33.7% of revenue, Korea 22.4% and Taiwan 18.7%.
What we think matters
- Return on capital of 64.5%
- Cash that arrives ahead of earnings
- A balance sheet in net cash
- A third of revenue in China, under export controls
- A tax rate that will not stay at 10.1%
- Two customers, a third of the business
How Lam Research makes money
Competitive advantage
The filing points to process complexity and to an installed base that generates spares, upgrades and services: customer support is 37.7% of revenue and fell far less than systems in the downturn.
Gross margin rose for a second year, from 44.6% to 48.7%, through a cycle that included a 14.5% revenue decline.
The company names competitors created and financially backed by foreign governments, and others not subject to US export controls who can sell where Lam cannot.
The filing warns those competitors may deeply discount or give products away, which bears directly on pricing power.
Pricing power
No prices or average selling prices are published, so pricing power has to be read from margin.
Gross margin of 48.7% against 44.6% two years earlier, achieved while the mix moved toward foundry.
Warranty estimates for pre-existing obligations were reduced by $57.5 million in the year, which flatters segment cost of goods sold by that amount.
Growth transparency
Growth is organic: no acquisitions in FY2025 or FY2024, and $120.0 million in FY2023.
FY2025 has 52 weeks against 53 in FY2024, and the filing does not quantify the extra week, so the 23.7% is understated by an unknown amount.
Systems grew 28.8% and customer support 16.1%.
Scalability
Revenue up 23.7% against operating expenses up 10.4%: research and development +10.2%, selling and administrative +13.1%.
Incremental operating margin of 46.4%, well above the 32.0% reported margin.
Capital intensity stays low at 4.1% of revenue even in a year when capex nearly doubled.
Catalysts identified in the filing
- $2.68 billion of deferred revenue, 80% due within a year
Deferred revenue rose to $2,681.1 million from $1,551.6 million, of which $2,150.3 million is expected to be recognised within twelve months.
- Capex up 91.4%
Capital expenditure reached $759.2 million, 1.97 times depreciation. Gross buildings went from $1,605.8 million to $1,914.6 million and long-lived assets in Southeast Asia from $390.5 million to $451.3 million.
- Mix moving to foundry, Taiwan and Korea
The foundry share of equipment revenue went from 38% in FY2023 to 45%. Taiwan more than doubled to $3,445.2 million and Korea grew 43.6%, while China's share fell from 42.2% to 33.7%.
- $7.5 billion of buyback authorisation left
$7,517.2 million remains available with no expiry, after $3,307.5 million was used during the year. A $500 million accelerated repurchase was due to settle in September 2025, after the filing was signed.

Key risks
The main weaknesses and risks identified in the latest annual report, in the order the report presents them.
- A third of revenue in China, under export controls
China is 33.7% of FY2025 revenue after 42.2% in FY2024. The filing states that the expansion of export licence requirements has limited the market, hurt revenue and increased exposure to foreign competition. Chinese revenue fell 1.4% in a year when the total grew 23.7%.
- A tax rate that will not stay at 10.1%
The effective rate is 10.1%; excluding only the release of uncertain tax positions it is 14.5%. The Malaysian incentive, which runs fifteen years from FY2022, saved $584.8 million, or $0.45 per diluted share. Gross uncertain positions are $720.3 million and tax years from 2005 are still open.
- Two customers, a third of the business
Two customers account for 17% and 15% of FY2025 revenue. The filing warns that the actions of even one customer can create variability, and says credit risk is concentrated among a few of them.
- Cash helped by customer deposits
The increase in deferred profit contributed $1,147.8 million, 18.6% of operating cash flow; without it operating cash flow is $5,025.5 million. Deferred revenue rose to $2,681.1 million from $1,551.6 million on advance deposits from newer customers the filing does not name.
- A cyclical business valued on its best year
FY2024 revenue fell 14.5% and operating income 17.6%, one year before this peak. At the same market capitalisation FY2024 earnings would be 32.14 times.
Open questions the filing does not answer
- How much of China revenue comes from domestic Chinese customers and how much from multinationals with fabs there? The filing combines the two.
- What were FY2025 transformational costs? The MD&A mentions them, the non-GAAP reconciliation does not exclude them, and no amount is given.
- How much did the 53rd week add to FY2024, and therefore what is growth on a like-for-like basis?
- What is revenue for deposition, etch and clean separately, and what are the market shares behind them?
- Who are the newer customers paying deposits, and what is their credit and export-licence profile?
- What will the July 2025 US tax act do to the FY2026 rate, which the company says it is still assessing?
- What is the near-doubling of capex for? The filing states neither the purpose nor the capacity it adds.
At $97.20 and 1,265,621,000 shares the market valued Lam at $123.02 billion, 22.96 times FY2025 earnings and 22.72 times free cash flow, a yield of 4.40% — 4.12% once share-based pay is treated as a cost. The shareholder yield from buybacks and dividends is 3.72%.
FY2025 is the best year of the three in the statements: revenue up 23.7% to $18.44 billion, operating margin from 28.6% to 32.0%, net income up 40.0%. Return on invested capital is 64.5% on a capital base that still carries $1.81 billion of goodwill and intangibles, free cash flow converts at 101.0% of earnings, and the balance sheet holds $1.63 billion of net cash with every note at a fixed rate.
The same market capitalisation is 32.14 times FY2024 earnings, and FY2024 was only one year earlier: a 4.40% yield on the peak year of a cyclical business assumes earnings do not fall back. Two further things flatter the year. The tax rate is 10.1%, and rises to 14.5% once the release of uncertain tax positions is stripped out; the Malaysian incentive alone is worth $0.45 per share, 10.8% of diluted earnings. And 18.6% of operating cash flow is the increase in deferred profit — customer deposits, not trading.
Strengths
- Return on capital of 64.5%
NOPAT of $5,306.8 million on invested capital of $8,227.5 million, against 47.0% in FY2024. The capital base includes $1,808.7 million of goodwill and intangibles, so the figure is not flattered by excluding acquisitions.
- Cash that arrives ahead of earnings
Free cash flow of $5,414.1 million is 101.0% of net income, and conversion was above 100% in all three years in the statements. Capital intensity is 4.1% of revenue even after capex nearly doubled.
- A balance sheet in net cash
Cash of $6,390.7 million against gross debt of $4,756.6 million including leases leaves $1,634.1 million of net cash. Every Senior Note is fixed-rate, the $2.0 billion revolver and the $1.5 billion commercial paper programme were undrawn, and interest cover is 33.1 times.
- Operating leverage that showed up on the way back
Revenue rose 23.7% and operating income 38.4%, an incremental operating margin of 46.4%, with every cost line growing more slowly than revenue. Research and development still grew 10.2%.
- An installed base that cushions the cycle
Customer support revenue is $6,944.3 million, 37.7% of the total. In the FY2024 downturn it fell 11.1% against 16.6% for systems.

What to watch in the next filing
- Gross margin. Below 47.3%, the FY2024 level, and the mix or the pricing is giving way.
- China as a share of revenue. A fall below 25% without an offset elsewhere, or a return above 42%, changes the risk profile.
- Free cash flow against net income. Below 90%, from 101.0%, and the cash is leaning on customer deposits rather than trading.
- Effective tax rate. Materially above the 14.5% computed without the uncertain-position releases, and a tenth of earnings goes with it.
- Days of inventory and receivables. Receivables grew 34.1% against revenue up 23.7%, taking days sales outstanding from 62.7 to 66.7.
