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

The Discounted Cash Flow (DCF) model estimates a company's intrinsic value by forecasting its future cash flows and then discounting those cash flows back to today to reflect their present value. This approach is particularly relevant for companies like T-Mobile US, where cash flow generation is a key determinant of long-term value.

T-Mobile US currently generates annual Free Cash Flow (FCF) of approximately $14.0 billion. According to analyst forecasts and extrapolations, this FCF is expected to steadily grow in the coming years, reaching around $24.1 billion by 2029 and continuing higher based on long-term projections. The DCF model used here applies a "2 Stage Free Cash Flow to Equity" methodology to reflect both short-term analyst estimates and longer-term expectations derived from historical trends.

After discounting these future cash flows back to today, T-Mobile US is estimated to have an intrinsic value of $529.28 per share. This represents a substantial discount to its current market price, suggesting the stock is undervalued by 60.9% at current levels.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests T-Mobile US is undervalued by 60.9%. Track this in your watchlist or portfolio, or discover 927 more undervalued stocks based on cash flows.

Approach 2: T-Mobile US Price vs Earnings

The Price-to-Earnings (PE) ratio is a widely used metric for valuing profitable companies like T-Mobile US. It gives investors a quick sense of how much they are paying for each dollar of earnings. A lower PE often suggests better value, but only when growth prospects and company quality are also considered.

When estimating a “normal” or “fair” PE, investors must look beyond current profitability. Expectations for future earnings growth, industry risks, and overall business stability all shape what level of PE is justified. For example, fast-growing or highly stable companies tend to command higher PE ratios, while riskier or slower-growing businesses typically trade at a discount.

As of today, T-Mobile US trades on a PE multiple of 19.5x. This is above the Wireless Telecom industry average of 18.3x, but below the average of its direct peers, which stands at 29.4x. Simply Wall St’s proprietary “Fair Ratio” factors in not only T-Mobile’s earnings growth outlook and risks, but also profitability, market cap, and broader industry dynamics. For T-Mobile US, the Fair Ratio is calculated at 16.4x.

The Fair Ratio provides a more accurate benchmark for value when compared to simple peer or industry averages because it adjusts for the unique mix of growth, profit margins, and risks in T-Mobile’s business. By contrasting the Fair Ratio (16.4x) with the current PE (19.5x), it suggests that T-Mobile US stock is modestly overvalued relative to its tailored fundamentals.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your T-Mobile US Narrative

Earlier we mentioned that there is an even better way to understand valuation, so let’s introduce you to Narratives. A Narrative is your story or perspective about a company, brought to life with assumptions about things like future revenue, earnings, margins, and ultimately a personal fair value estimate. Think of it as connecting what you believe about T-Mobile US’s future to what you think the share price should be today.

With Narratives, the numbers are backed by your logic and reasoning, making investing less about guesswork and more about considered judgement. Narratives are available within the Simply Wall St Community page, where millions of investors can easily create, compare, and update these forecasts.

This tool helps you make smarter decisions by letting you compare your fair value to the current market price. This signals when you might consider buying or selling. Narratives automatically update as new information, like earnings reports or major news, is released, so your outlook can evolve with the company.

For example, some investors currently believe T-Mobile US could be fairly valued at up to $309.00 based on strong growth in 5G and broadband, while others see fair value closer to $200.00 due to concerns over profitability and competition. Which Narrative fits what you believe?
