Lam Research, incorporated in 1980 and based in Fremont, California, makes wafer fabrication equipment — deposition, etch and clean systems — and provides spares, upgrades and services for its installed base. Fiscal 2026 revenue (year ended June 28, 2026) rose 26% to $23,233 million, driven by foundry customers: systems revenue was $14,885 million and customer support-related revenue $8,347 million.

  • ▲

    Revenue grew +9.7% a year over 5 years (strong growth)

    From $14.63B in FY2021 to $23.23B in FY2026. The annualized rate (CAGR) makes it possible to compare growth pace across companies of different sizes.

  • ▲

    Operating margin improved: 30.6% → 35.3%

    How much operating profit is left per $100 of revenue. It moved +4.7 points over 5 years — pricing power, cost control, and product mix all show up here.

  • ▲

    Equity ratio is 53.0% (a high level of financial stability)

    The share of total assets funded by equity rather than debt. 50%+ is often read as low bankruptcy risk, though the right level varies by industry (real estate and leasing run lower, for instance).

  • ▲

    Free cash flow was positive in 6 of 6 years

    Operating cash flow minus capital expenditures: the cash left over after funding the business’s own investment, available for dividends, buybacks, acquisitions, or debt paydown. A negative year can mean heavy investment, or weak core earnings — worth distinguishing.

  • ▲

    ROE averaged 61.8% over 6 years (latest: 65.1%)

    How much profit was generated on shareholders’ equity. Roughly 10%+ is often cited as solid for a U.S. company, though this varies a lot by industry and capital intensity.

Is ROIC above WACC?From SEC data

ROIC (the return on money invested in the business) above WACC (the cost of raising that money) means the company is creating value. WACC is an estimate, so its assumptions can be adjusted below.

ROIC (FY2026)

47.5%

What the price implies (DCF)From SEC data

A company's value can be written as its free cash flow divided by (cost of capital − perpetual growth). Working that backwards from the market's valuation shows how much growth the share price assumed — compared here with the company's actual past growth.

Growth the price implies (price on 2026-11-04)

12.6%

Perpetual FCF growth: g = r − FCF ÷ EV = 14.3% − 1.7%

Past FCF growth (FY2021–FY2026)

+8.6%

Compound annual rate, 5 years

Past revenue growth (FY2021–FY2026)

+9.7%

Compound annual rate, 5 years

Inputs (FY2026): free cash flow $4.89B (operating CF − capex); enterprise value $287.93B = market cap $289.78B (latest close, 2026-11-04) + debt $3.72B − cash and short-term investments $5.58B; r = WACC of 14.3% using this page’s default assumptions (β 1.72, risk-free 5.0%, market premium 5.5%).

Three WACC scenarios

The same calculation under cautious, base and optimistic cost-of-capital assumptions (risk-free rate fixed at the 10-year Treasury yield). Pick one to load it into the sliders below.

Try your own assumptions

V = FCF ÷ (r − g). It starts at the implied growth rate, where the theoretical value equals today’s enterprise value.

Theoretical enterprise value

$212.66B

FCF $4.89B ÷ (14.3% − 12.0%)

Theoretical ÷ actual enterprise value

0.74x

Below 1x: these assumptions value the business below the market did

How sensitive the answer is

Theoretical ÷ actual enterprise value for each combination of r and g.

g \ r12.3%13.3%14.3%15.3%16.3%

6%0.27x0.23x0.20x0.18x0.16x
8%0.40x0.32x0.27x0.23x0.20x

A simplified model for seeing what the market price assumes, not a forecast or a target price. It treats free cash flow as growing at one constant rate forever; the result swings widely with small changes in r and g, and is undefined when g reaches r. Free cash flow here is operating cash flow minus capex, which is after interest — a full DCF of enterprise value would use cash flow before interest. Market cap uses the latest close (2026-11-04) × shares at fiscal year-end; free cash flow and WACC inputs are from the latest fiscal year.

Earnings qualityFrom SEC dataShow

The same reported profit can mean different things depending on whether it's backed by cash, driven by the core business, or the result of a one-off item. Four checks below.

  • !

    Operating CF ÷ net income: averages 0.99x

    Cash coming in trails reported profit. Worth checking for rising receivables/inventory or one-off gains.

  • !

    Accrual ratio (latest): 6.3%

    A larger share of profit is non-cash accruals, which research associates with profit that tends to fade in later periods.

  • ✓

    Core-earnings share (operating income ÷ pretax income): 99%

    Most profit comes from core operations.

  • ✓

    Days sales outstanding: 76 → 68 days

    No major slowdown in collecting on sales.

Impact is judged from how large the affected business is relative to total revenue/profit, and from the risk’s track record of moving results in the past. Likelihood is judged from the filing’s wording and the current business environment (already occurring, or recurring). See the rating criteria.

  • Recommendations made by the Organization for Economic Co-operation and Development’s Base Erosion and Profit Shifting 2.0 (“BEPS 2.0”) project have the potential to lead to changes in the tax laws in numerous countries, including the implementation of a global minimum tax. Several countries around the world have enacted or proposed changes to their existing tax laws based on these recommendations. As each country in which we operate evaluates their alignment with the recommendations and enacts minimum tax rules, the ultimate impact of any such changes on our effective tax rate remains uncertain. When fully enacted, such changes could have a material impact on our effective tax rate. We will continue to monitor the progress of the BEPS 2.0 implementation.
