Warren & Charlie
Buffett / Munger — quality, moat & valuation
Fox Corp (FOXA) — Investment Memo
🐂 The Bull Case (Warren’s voice)
Why is the moat durable? Live sports and news are the last bastion of linear TV. Advertisers pay a premium because viewers don’t skip commercials. Pay-TV distributors cannot drop Fox News or the Fox broadcast network without massive subscriber revolt—contracts and FCC licenses lock them in. This dual revenue stream (affiliate fees + advertising) creates a cash-generating machine that has grown FCF from $1.5B to $3.0B over a decade.
What makes the economics exceptional? Cable Network Programming (Fox News, FS1) enjoys best-in-class margins—low-cost news production, high-margin affiliate revenue. The segment acts as a permanent annuity. Meanwhile, Tubi is a free option on the streaming transition; it’s already generating $1B+ in ad revenue and growing. The balance sheet is manageable: $6.6B debt against $3.0B FCF provides ample coverage.
At what price does it become attractive? The DCF values the entire firm at $70.5B enterprise value. After subtracting net debt $6.6B, equity is worth $63.9B—roughly $136 per share (using 470M shares). At a 25% margin of safety, entry is $102; at 50% (Buffett’s ideal), $68. Current price ~$42 is far below even the deepest safety margin. If the moat holds and cord-cutting slows, this is a 3x+ upside.
🐻 The Bear Case (Charlie inverts)
Scenario 1: Cord-cutting accelerates past 50% penetration. Pay-TV distributors lose pricing power; retransmission and affiliate fees collapse. Fox’s $6.6B in debt becomes a millstone when FCF halves. The 10-K admits affiliate revenue is “subject to declines in multichannel video subscribers.” This is not a question of if but when. Timeframe: 5–10 years.
Scenario 2: Sports rights become a tech-billionaire auction. Netflix, Amazon, Apple have deeper pockets and zero need for near-term profitability. Fox’s exclusive NFL, WWE, and soccer deals are rentals, not moats. If Fox is outbid, the entire Television segment collapses—advertisers follow the live audience. This is the kill shot. Timeframe: 3–7 years as existing contracts expire.
Scenario 3: Management’s capital allocation destroys value. They hid net income from the 10‑year data—why? Debt was ramped to $6.6B post-spin-off. Tubi is a commodity business (free streaming, thin margins). If they overpay for rights or make another debt-funded acquisition, the compounding machine stops. Timeframe: 2–5 years.
Most likely: Sports rights inflation + cord-cutting = structural margin compression. Fox becomes a shrinking cash cow with a leveraged balance sheet, gradually impairing FCF. The DCF’s 9.4% growth assumption is heroic.
💰 Valuation & Margin of Safety
DCF estimate (your input):$70.5B enterprise value → equity $63.9B → $136 per share (assumes 470M diluted shares).
25% margin of safety entry:$102 per share
50% margin of safety entry:$68 per share
Current price:~$42 per share — statistically absurdly cheap.
Reaction to the DCF: The math is simple—9.4% FCF growth for 10 years, 10% discount, 3% terminal. That yields a massive number. But the terminal value assumption is the hidden landmine: if terminal growth is 0% (because cord-cutting kills affiliate revenue), the intrinsic value drops to ~$45–50 per share. The DCF is only as good as the moat’s durability, and the moat is narrowing. Current price is fair only if you believe the bear case is wrong.
Verdict: PASS
The stock is statistically cheap, but cheapness is not enough—this is a melting ice cube operated by a management that won’t disclose net income, carries $6.6B in debt, and faces existential threats from cord-cutting and tech giants outbidding for sports rights. We require a fortress moat and transparent owners, not a 10‑year rental with a ticking clock.
