Warren & Charlie
Buffett / Munger — quality, moat & valuation
Fox Corp (FOX) — Investment Memo
🐂 The Bull Case (Warren's voice)
The Last Great Aggregator: In a world of fragmented streaming, live sports are the only "appointment viewing" left. Fox doesn't just sell ads; they own the destination for the NFL and MLB. That is a fortress.
Toll-Bridge Economics: The FCC licenses and exclusive sports rights create a regulatory moat. If a competitor wants to play in this league, they don't just need money; they need government permission and rights that are already locked in a vault.
Operating Leverage: Revenue grew $6.4B since 2017, but FCF grew faster. When the rights fees are fixed, every additional ad dollar drops straight to the bottom line.
The "Buyback" Engine: Management isn't great at inventing new things, but they are proficient at returning capital. If they keep buying back shares while FCF grows at 9.4%, the per-share value compounds even if the business stays stagnant.
Attractive Entry: This becomes a "Berkshire business" if we can buy it at a price that assumes the cable bundle dies slowly, but the sports rights remain dominant.
🐻 The Bear Case (Charlie inverts)
The Cord-Cutting Cliff: The "toll bridge" is built on the cable bundle. If the bundle collapses faster than Fox can pivot to a direct-to-consumer model, the carriage fees—the bedrock of their revenue—evaporate. We are betting on a dying distribution system.
The NFL Mutiny: The ultimate risk is the NFL deciding they no longer need a middleman. If the league moves to a proprietary, global streaming platform, Fox goes from being a "toll bridge" to a "landlord with an empty building."
The "Corpse" in the Closet: The missing Net Income data is a flashing red light. If you can't see the bottom line, you're guessing at the margins. The erratic FCF suggests a business that is capital-intensive and prone to sudden, expensive shocks.
Most Likely Death: Structural decline of linear TV. Timeframe: 3–7 years. It's not a crash; it's a slow bleed.
💰 Valuation & Margin of Safety
Intrinsic value estimate: $141 per share (Based on $70.5B total DCF).
25% margin of safety entry: $105.75(Conservative).
50% margin of safety entry: $70.50(Buffett's ideal).
Current Status: Fairly valued to slightly expensive. We are paying for the "hope" of margin expansion, but we aren't getting a discount for the structural risk of the media industry.
Verdict: WATCH
The moat is real, but the bridge is crumbling. We cannot commit capital while the bottom-line earnings remain opaque and the cable bundle is in retreat. We wait for a panic that brings the price down to $100 or lower.
