Warren & Charlie
Buffett / Munger — quality, moat & valuation
NETFLIX INC (NFLX) — Investment Memo
🐂 The Bull Case (Warren's voice)
The Toll Bridge: Netflix has successfully transitioned from a DVD-by-mail experiment to a global utility for leisure. It is a digital toll booth where the price of entry is a recurring monthly fee.
Economies of Scale: The beauty of the model is that the cost of producing Stranger Things is the same whether 1 million or 200 million people watch it. As the subscriber base grows, the content cost per user plummets, creating massive operating leverage.
Pricing Power: The ultimate test of a moat is the ability to raise prices without losing customers. Netflix has done this repeatedly. They possess the psychological real estate in the consumer's mind; for most, it is the "default" streaming service.
Capital Discipline: Management has finally stopped the "growth at any cost" madness. Moving from a $3.1B FCF burn to $9.5B in generation is a fundamental shift in character from a venture-backed startup to a mature business.
Attractiveness: This becomes a Berkshire-grade asset when the price reflects a stable utility rather than a growth lottery ticket. We want it when the market forgets that "boring" cash flow is better than "exciting" subscriber growth.
🐻 The Bear Case (Charlie inverts)
“Show me where I’ll die and I won’t go there.”
The Content Treadmill: Unlike a brand like See's Candies, Netflix cannot stop investing. If they stop spending billions on new content, the library becomes stale and churn spikes. It is a leaking bucket; they must spend $17B+ annually just to keep the customers they already have. It is a "moat" that requires constant, expensive dredging.
The Commodity Trap: When every studio (Disney, Warner, etc.) has its own app, content becomes fragmented. If Netflix loses its "must-have" status and becomes just another app in a folder, they lose their pricing power. They move from being the curator to being a commodity.
AI-Generated Displacement: The most permanent threat is a structural shift in how entertainment is consumed. If generative AI allows users to create their own personalized, high-fidelity entertainment on demand, the entire concept of a centralized content library evaporates overnight.
Most Likely Failure: The Content Treadmill. Over a 5–10 year horizon, the cost of talent and production may outpace the ceiling of what a household is willing to pay for a subscription.
💰 Valuation & Margin of Safety
The DCF provided is brutally conservative, reflecting a business that has been stripped of its "growth premium" and valued as a steady-state cash cow.
Intrinsic value estimate: $80.28 per share
25% margin of safety entry: $60.21(conservative)
50% margin of safety entry: $40.14(Buffett's ideal)
Current Status: Grossly Expensive. Based on the DCF provided, the market is pricing in growth rates far beyond the 15% FCF growth assumption. The gap between intrinsic value ($80.28) and current market price is an unbridgeable chasm.
Verdict: PASS
The business is a wonderful machine, but the price is a fantasy. We do not buy wonderful businesses at any price. At $80.28 intrinsic value, the current market price is an exercise in delusion.
