The assumptions both views share

These are neutral settings, the same for every company. Each view holds them and solves for one driver at today's price.

Worth knowing

  • Revenue grew 14.8% a year over five years and grew 10.0% over ten: the record points two ways.
  • Its industry's margin today is more than 3 points away from its median over the last 6 years of industry data.

This is a mechanical starting point with neutral assumptions, not a valuation. The story decides.
