Fast grower with 26.8% revenue growth trades at 34.75x earnings while insiders sell quarter after quarter.

cautiousBullishconviction

This framework sees a genuine fast grower with clear fundamentals trading at a price that assumes semiconductor cycles have been permanently abolished.

THE LENSES
THE CLASSIFICATIONexceptional

What type of company is this, and what should we expect?

TTM revenue grew 26.8% to record $5.34B in Q4'25
Operating margins expanded from 14.5% cycle low to 33.9% in Q4'25
Net income reached 95th percentile of 10-year range
Revenue growth accelerating from negative in 2023 to 26.8% today

This framework classifies Lam Research as a fast grower — revenue above 20%, margins expanding, execution improving. These are the companies where Lynch found his 10-baggers, though the semiconductor equipment industry adds cyclical characteristics that pure fast growers lack.

Revenue
THE GROWTH STORYclear

Can you explain why this company grows in one simple sentence?

System sales comprise 62.3% of revenue selling deposition and etch equipment
Customer Support generates 37.7% providing recurring service revenue
China represents 33.7% of FY2025 revenue, Korea 22.4%, Taiwan 18.7%
Revenue mix shows clear semiconductor manufacturing equipment focus

The growth story is crystal clear: Lam Research sells the equipment that makes computer chips, and chip demand keeps growing. An eleven-year-old understands this — more phones, cars, and AI means more chips needed.

Revenue by Segment
THE PEG RATIOreasonable

Is the price reasonable relative to the growth rate?

P/E ratio at 34.75x in Q4'25 at 98th percentile of 10-year range
TTM earnings grew from losses in 2022 to record levels
26.8% revenue growth suggests earnings growth similar or higher
PEG approximately 1.3 (34.75 P/E divided by ~27% growth)

Applying this lens shows a PEG around 1.3 — paying modest premium for the growth. Lynch would find this acceptable if growth continues, though he'd note the cyclical risk in semiconductor equipment that could quickly change the math.

P/E Ratio
WHERE IN THE STORYmature

Are we in the early, middle, or late innings of this growth story?

Revenue at record $5.34B in Q4'25 after recovering from 2023 downturn
Operating margins at 33.9% near peak levels (95th percentile)
Institutional ownership at 82.95%, up 3.15pp in one quarter
P/E at 98th percentile suggests market fully aware of the story

This framework sees middle-to-late innings. The easy gains from the 2022 bottom are behind us — the stock already rose 139% from average buyback prices. Growth is established, margins peaked, institutions piled in. The story is well-known.

VERDICT

Applying this framework reveals a textbook fast grower executing brilliantly but priced as if semiconductor cycles have been repealed. The growth story couldn't be clearer — they make the tools that make the chips powering everything digital. Yet at 34.75x earnings with insiders selling and institutions at 83% ownership, the easy money has been made. Would Lynch rather own this exceptional business at a fair price or hunt for the next undiscovered fast grower trading at 15x?
