Discounted cash flow$1,768.02+224.3%free cash flow $4.17bn, growth 44.37% for 5 years, then fading to 3% over 5 more, discounted at 12.38%; stress floor $444.44
Exit multiple (P/E)——no exit multiple: the five-year median of 24.3x is 1.8x the 13.6x this name trades at today (limit 1.5x) — the market has re-rated the name, so its own history prices a business it is no longer paid for. The forward PE is not a substitute: it is today's price divided by earnings, and an anchor built from it can only restate the price
Sum of the parts——no sum of the parts: this run holds no segment disclosure for the name
Price to sales——not reached: the cash-flow or earnings methods produced an anchor, so this fallback was not run
Tangible book——used only for lenders, where book value is the business
Price to FFO (REITs)——used only for REITs
