How this TMUS valuation is built
The model projects ten years of T-Mobile US Inc's free cash flow to the firm and discounts each year at its own cost of capital. Rather than assuming today's growth and margins persist forever, a moat-scoring step — weighing T-Mobile US Inc's ROIC-versus-WACC spread, gross-margin trend, and reinvestment efficiency — decides how many years the business holds its edge before its economics mean-revert toward the Damodaran NYU benchmarks for its industry.
WACC is rebuilt each year from an unlevered-then-relevered beta and the company's evolving capital structure; terminal value uses the Gordon growth model with a reinvestment rate tied to the return earned on new capital (goodwill stripped out to reflect operating efficiency). Every assumption — growth, margins, tax, leverage, convergence timing — is editable, and running the full interactive model adds a 10,000-draw Monte Carlo simulation and WACC-versus-terminal-growth sensitivity heatmaps.
