At $213.66, Lam Research offers 72 cents of earnings per $100 invested while treasuries pay $4.33.
A superb business executing at peak efficiency trades at a price that assumes semiconductor equipment demand will never experience another downturn.
Does this business have a durable competitive advantage?
This framework sees a wide moat in specialized semiconductor equipment that customers cannot easily replace. The sustained high margins through industry cycles and consistent execution demonstrate pricing power that only comes from indispensable products.
If you bought this entire business today, would what it earns justify what you paid?
Applying this lens, the math does not work for a permanent owner. At 0.72 cents of earnings for every dollar invested versus 4.33 cents from treasuries, an owner is paying a massive premium for growth that may not materialize in a cyclical industry.
How much cash does this business really generate for its owners?
This framework appreciates businesses that convert earnings to actual cash, and Lam Research excels here. The company generates real owner earnings well above accounting profits, with minimal dilution from stock compensation.
Are the managers acting as owners or as agents?
This framework sees mixed signals - past buybacks were brilliantly timed, but current buybacks at record valuations consume nearly all cash flow. The persistent insider selling while aggressively buying back shares raises questions about capital allocation priorities.
Applying this framework reveals a magnificent business trading at an unmagnificent price. Lam Research possesses the competitive advantages and cash generation this framework seeks, but at 139 times free cash flow, the owner's math simply doesn't work. The market has bid up this quality franchise to levels that assume semiconductor equipment demand will grow forever without interruption. Would you pay $28.9 billion for a business that generates $217 million in owner earnings?
