Rewards

BRK-B
  • Each dollar of retained earnings has created $3.95 of earning power — management is an exceptional capital allocator.
  • PEG ratio of 0.13 suggests the stock is undervalued relative to its growth rate — paying less than 1x for each unit of earnings growth.
  • Net debt/EBITDA of -2.3x means the company holds more cash than debt — a net cash position.
WBD
  • FCF yield of 23.7% is historically attractive — the business generates significant cash relative to its price.

Risks

BRK-B
  • FCF yield of 6.0% suggests reasonable valuation assuming continued moderate growth.
  • Trailing P/E of 15.2x is 72% above the historical average of 8.9x — the stock trades at a premium to its own history.
WBD
  • PEG ratio of 216.92 indicates the stock is expensive relative to its expected growth — the market may be pricing in more growth than analysts project.
  • Net debt/EBITDA of 4.4x indicates heavy leverage — it would take over 4 years of EBITDA to pay off net debt.
  • Altman Z-Score of 0.94 places the company in the distress zone — financial patterns resemble those of companies that experienced bankruptcy.
