Valuation methods

MethodValuevs priceBasis
Discounted cash flow——the free cash flow base is 0.86% of market cap (floor 1%) — the terminal value carries the answer, not the cash flows
Exit multiple (P/E)——no exit multiple: the five-year median of 52.8x is 1.7x the 31.2x 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$1,254.90-13.3%the stock's own median price-to-sales of 16.51×
Tangible book——used only for lenders, where book value is the business
