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.
- Reinvestment
- $4.36 of revenue for each $1 investedThe industry's sales-to-capital ratio: how much new capital growth needs.Damodaran Online, January 2026 industry data, Engineering/Construction
- Cost of capital
- 8.86%The return investors need for the risk: the industry's beta, the market's risk premium, and debt rated A1/A+ from its median margin, with a stated 5-year debt maturity. Built by the engine from the parts listed under Sources, each with its date.
- After year 10
- Growth at the riskfree rate, foreverNew investment earns its cost of capital and no more, so growth after year 10 adds no value, and the cost of capital moves to a mature company's.
Worth knowing
- Revenue grew 20.5% a year over five years and grew 14.2% over ten: the record points two ways.
- Revenue grew 20.5% a year over five years, faster than 20%: a steady-company starting point fits it less well.
This is a mechanical starting point with neutral assumptions, not a valuation. The story decides.
