Why Is Everyone Ignoring T-Mobile Stock’s High Cash Yield?

Shares of T-Mobile US (TMUS) currently trade 45.5% below their two-year high. Following that decline, the company generates a massive amount of cash relative to its market size. T-Mobile produced free cash flow equal to 10.1% of its market value over the last twelve months, compared with 4.5% for the median S&P 500 company. A yield that high means a cheap business, or one that investors expect to shrink. So why is the market paying so little for T-Mobile’s cash?

What A T-Mobile Shareholder Actually Owns

Buying shares gives an investor a claim on the cash T-Mobile has already produced. Free cash flow belongs to the shareholders just as corporate profit does, whether it is paid out or not. Share prices historically gravitate toward the cash a business generates over time, particularly when the business is growing.

T-Mobile builds that cash by selling wireless service and 5G broadband. Over the last twelve months, the company retained 20.1% of its revenue as operating profit, outpacing the 18.5% margin recorded by the S&P 500. Capital spending consumed 44% of the cash generated by operations, while the rest was free cash flow. That free cash flow stayed positive through every twelve-month stretch of the past three years, and it grew by about 32% in the latest twelve months.

That cash does not belong exclusively to equity holders, however. Lenders hold priority claims on the balance sheet. Because T-Mobile carries net debt equal to 72.6% of its market value, part of the cash must first service those obligations. When measured against the combined total of market value plus net debt, the yield adjusts to 5.9%.

Why Is The Market Wary Of T-Mobile?

The current stock price suggests investors expect T-Mobile to face slowing growth alongside a heavy debt load. Revenue expanded by 7.9% from a year earlier in the second quarter of 2026, which marks a deceleration from the 10.6% growth posted in the first quarter. Management also forecast service revenue growth of about 6% for the recently ended, though not yet reported, third quarter. That forecast sits below the 9% service revenue growth achieved in the second. Profitability has thinned in tandem: the operating margin contracted to 20.1% over the last twelve months, compared with 23% a year earlier.

During the July 23 call, management addressed the prospect of slower EBITDA growth in the second half of the year, attributing the shift to the timing of past acquisitions. Notably, T-Mobile bought UScellular last year. Management also cautioned that an overhaul of older rate plans during the third quarter would temporarily cause more customer accounts to leave. Even with those headwinds, management raised its 2026 forecasts for operating cash flow and adjusted free cash flow in July. That improved free cash flow outlook materialized mainly because of lower cash income taxes.

Slower expansion does not mean the company is shrinking, however. While quarterly momentum has cooled, total revenue over the last twelve months still grew 9.7%, helped by acquisitions. That compares favorably against the 6.3% growth recorded the year before. These figures portray a growing business at a cheap price rather than a shrinking enterprise. Ultimately, the debt burden and the moderating growth rate appear to be the reasons for the valuation discount.

Can T-Mobile Afford Its Debt?

T-Mobile can service its obligations today. Over the last twelve months, the company generated enough operating profit to cover its interest bill 4.6 times. However, management noted on the July 23 call that it is actively preserving budget room to purchase spectrum in 2027 and 2028. Because of those upcoming capital demands, the debt may not fall quickly.

Two central questions remain open. T-Mobile saw its free cash flow rise about 32% over the last twelve months. Does it keep growing? And does T-Mobile start to bring down its net debt, now 72.6% of market value? T-Mobile is due to discuss its third quarter results on October 28, 2026. Service revenue growth above the 6% management forecast for that quarter would show the slowdown is milder than the price appears to assume.
