Summary

Our base-case estimate uses a two-stage discounted cash flow model based on free cash flow. We then blend that result with the average analyst price target of $115.40 from 26 analysts, using a 25% weight on analyst consensus. That produces an estimated intrinsic value of $40.42 per share.

Warnings

Wall Street's average price target is $115.40 (from 26 analysts). Our estimate is 87% below the consensus -- consider that gap carefully.

Key Risks

  • P/E alone misleads — earnings depressed by growth investment
  • Cyclical or commodity businesses may be misclassified as platforms
  • Terminal value dominance suggests sensitivity to long-run assumptions
