Approach 1: T-Mobile US Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model projects a company’s future cash flows and then discounts them back to today’s dollars to estimate what the business might be worth right now.

For T-Mobile US, the model uses a 2 Stage Free Cash Flow to Equity approach based on cash flow projections. The latest twelve month free cash flow is about $15.3b. Analyst estimates and subsequent extrapolations by Simply Wall St project free cash flow of $24.4b by 2030, with a detailed path of projected cash flows from 2026 through 2035 that are discounted back to today.

Putting this together, the DCF model arrives at an estimated intrinsic value of about $557.67 per share. Against the current share price of about $201.40, this implies the stock is 63.9% undervalued according to these cash flow assumptions.

For readers who put the most weight on cash generation, this model points to a wide gap between price and estimated value.

Approach 2: T-Mobile US Price vs Earnings

For profitable companies, the P/E ratio is a useful way to connect what you pay for each share with the earnings that back it. It helps you see how many dollars of price the market is placing on each dollar of current earnings.

What counts as a “normal” P/E depends on how fast earnings are expected to grow and how risky those earnings look. Higher expected growth and lower perceived risk can support a higher P/E, while slower growth or higher risk usually point to a lower, more cautious multiple.

T-Mobile US currently trades on a P/E of about 20.19x. That sits above the Wireless Telecom industry average of about 17.12x, although it is below the peer group average of about 33.59x. Simply Wall St’s Fair Ratio for T-Mobile US is 16.16x. This Fair Ratio is a proprietary estimate of what the P/E might be given factors such as earnings growth, industry, profit margins, market cap and company specific risks. Because it blends these elements, it can be more tailored than a simple comparison against peers or the broad industry.

Comparing the Fair Ratio of 16.16x with the current P/E of 20.19x suggests the shares are trading above that tailored reference point.

Result: OVERVALUED
