T-Mobile US reported higher service revenue and a faster increase in earnings per share for the third quarter of 2026. Its results show why investors should examine the number of customer accounts, revenue per account and cash flow alongside the bottom-line headline.
In its October 28 earnings release, the company reported service revenue of $19.4 billion, up 6% year over year, and diluted EPS of $3.22, up 34%. Figures are U.S. dollars. The earnings call was scheduled for 4:30 p.m. Eastern Daylight Time after the regular U.S. market session.
What does revenue per account tell us?
T-Mobile reported postpaid average revenue per account, or ARPA, of $155.73, up 4% from a year earlier, and 274,000 net postpaid account additions. An account can include more than one line, so revenue per account and revenue per individual customer are not interchangeable.
Higher average revenue can result from changes in plans, services or account mix. More accounts can help revenue grow even without the same change in revenue per account. To evaluate the business, readers should also consider customer retention and the cost of acquiring and serving those accounts.
Why can EPS grow faster than revenue?
Per-share earnings are affected by profit margins, financing, taxes and the number of diluted shares, among other factors. The company also repurchased shares during the quarter. Repurchases can change the denominator in an EPS calculation, but they are not the only possible reason EPS changes.
It would be too simple to attribute the entire increase to one factor without walking through the full financial statements. Net income rose 27% to $3.5 billion, while diluted EPS increased 34%; the different growth rates are a prompt to review the share count and other details.
Cash flow and investment
The company said operating cash flow declined 2% to $7.3 billion, while adjusted free cash flow rose 5% to $5.1 billion. Adjusted free cash flow is a company-defined measure, so its reconciliation helps explain why it moved differently from operating cash flow.
Telecommunications networks require ongoing investment. A quarter with lower cash purchases of property and equipment does not automatically mean long-term investment needs have disappeared. Spectrum, network capacity and competition remain relevant to future cash needs.
What matters for a long-term view?
Consider account growth, retention, pricing, network investment, leverage and how much cash remains after necessary spending. A rising EPS figure is useful information, but it does not by itself establish the value of a stock or its suitability for an individual investor.
