T-Mobile US (TMUS) Earnings: Q3 2026 Results

The quarter ended September 30, 2026 and T-Mobile US published the results on October 28, 2026. Revenue and diluted EPS are shown against Q3 2025, the same quarter a year earlier, which takes seasonal swings out of the comparison.

• In Q3 2025 T-Mobile acquired 1,448,000 postpaid accounts through the UScellular acquisition and 633,000 from Metronet and other acquisitions, so the year-over-year comparison includes a partial year-ago quarter of those accounts.
• T-Mobile operates as a single operating segment, Wireless; the rows above are the revenue lines in its income statement.

• T-Mobile US's Equipment revenues revenue was $3.9 billion in Q3 2026, up 13% from $3.5 billion in Q3 2025, 17% of total revenue.
• T-Mobile US's Other revenues revenue was $280 million in Q3 2026, up 12% from $251 million in Q3 2025, 1% of total revenue.

Segment lines are the figures writers cite most often, because they show where the growth in a quarter came from. Companies redraw their segments from time to time and restate the prior year to match, so a year-ago figure here can differ from the one printed a year ago. When that has happened, the note above says so.

From the earnings release

T-Mobile does not forecast net income or EPS; it says it cannot do so without unreasonable efforts.

In its Q3 2026 release, T-Mobile US said:

“Postpaid net account additions are expected to be approximately 1.0 million, at the midpoint of the previous guide of 950 thousand to 1.05 million.”

“Effective tax rate is now expected to be between 24% and 25%, a decrease from prior guidance of between 25% and 26%.”

“Core Adjusted EBITDA, which is Adjusted EBITDA less lease revenues, is expected to be between $37.35 billion and $37.45 billion, an increase at the midpoint from prior guidance of $37.1 billion to $37.5 billion.”

“Adjusted Free Cash Flow, including net payments for UScellular merger-related costs, is now expected to be between $18.7 billion and $18.8 billion, an increase at the midpoint from prior guidance of $18.4 billion to $18.8 billion.”

Each quarter keeps its own page with the figures as reported, so a link to one stays pointed at the same numbers after the next report.

• Q3 2026 (this page), reported Oct 28, 2026

T-Mobile US operates as a single segment, Wireless, and splits revenue into service and equipment. In Q3 2026 total service revenues were $19,375 million of $23,584 million, up 6.2%, and postpaid revenues alone were $16,269 million, up 9.3%. Equipment revenues were $3,929 million, prepaid revenues $2,427 million and wholesale and other service revenues $679 million. (T-Mobile Q3 2026 earnings release, Oct 28, 2026; T-Mobile Q3 2026 Investor Factbook, Oct 28, 2026; T-Mobile Form 10-Q, Q3 2026, Oct 28, 2026)

T-Mobile attributes postpaid service growth to more average postpaid accounts, including those from the UScellular and Metronet acquisitions in Q3 2025, and to higher postpaid ARPA. Postpaid ARPA was $155.73, up 4% from $149.44, and total postpaid accounts were 34,974 thousand, against 33,979 thousand a year earlier, after 274 thousand net account additions in the quarter. (T-Mobile Q3 2026 earnings release, Oct 28, 2026; T-Mobile Q3 2026 Investor Factbook, Oct 28, 2026)

Equipment revenues rose 13%, which T-Mobile put down to higher average revenue per device sold, driven by a richer high-end phone mix and higher manufacturer pricing, plus higher liquidation revenue, partly offset by fewer devices sold, mainly prepaid. Prepaid revenues fell to $2,427 million from $2,625 million. (T-Mobile Q3 2026 Investor Factbook, Oct 28, 2026)

Beyond phones, T-Mobile sells broadband: its postpaid accounts include 5G broadband gateways and fiber connections alongside tablets, wearables and other connected devices. Postpaid account churn rose to 1.09% from 0.97%, which T-Mobile linked to more broadband-only accounts, which churn more, and the temporary impact of its rate plan modernization.

T-Mobile US reports only GAAP EPS; its main non-GAAP measures are Core Adjusted EBITDA and Adjusted Free Cash Flow. Q3 2026 diluted EPS was $3.22, up 34% from $2.41. It included UScellular merger-related costs of $98 million after tax, or $0.09 a share, against $0.05 a year earlier, and the year-ago quarter included a $208 million after-tax impairment of capitalized software development costs, or $0.18 a share.

Buybacks shrank the share count: diluted weighted-average shares were 1,071,630,434 against 1,126,627,708 a year earlier. T-Mobile returned $3.5 billion in the quarter, $2.4 billion in repurchases and $1.1 billion in dividends, under an authorization of up to $18.2 billion through December 31, 2026. (T-Mobile Q3 2026 Investor Factbook, Oct 28, 2026; T-Mobile Q3 2026 earnings release, Oct 28, 2026)

Interest expense, net was $1,031 million, up from $924 million, and income tax expense was $1,085 million on pre-tax income of $4,540 million, about 24%. T-Mobile lowered its full-year effective tax rate outlook to between 24% and 25%. (T-Mobile Q3 2026 Investor Factbook, Oct 28, 2026; T-Mobile Q3 2026 earnings release, Oct 28, 2026)

Diluted EPS divides net income by the weighted average number of shares outstanding in the quarter, plus the shares that options and other equity awards could add. Buybacks shrink that count and lift EPS for the same profit; share issuance and stock awards enlarge it.

T-Mobile US publishes full-year guidance in each release and updated it for 2026: Core Adjusted EBITDA of $37.35 billion to $37.45 billion, up at the midpoint from $37.1 billion to $37.5 billion; Adjusted Free Cash Flow of $18.7 billion to $18.8 billion; capital expenditures of approximately $10.0 billion; and postpaid net account additions of approximately 1.0 million. (T-Mobile Q3 2026 earnings release, Oct 28, 2026)

T-Mobile gives no net income or EPS forecast, saying it cannot forecast net income without unreasonable efforts because of items such as Special Items, income tax expense and interest expense. (T-Mobile Q3 2026 earnings release, Oct 28, 2026)

A consensus figure is the average of the models published by the analysts who cover T-Mobile US, collected by a data provider and revised up to the day of the report. A quarter that lands above it says how expectations were set as much as how the business did, and the share price on the day also reflects the guidance and the lines no consensus covers.

The consensus figures on this page are Yahoo Finance's, as pulled on the date shown. Each comes with the number of analysts behind it; the smaller that number, the more one revised estimate can move the average.

The figures below are the ones T-Mobile US's own release and filings put weight on for Q3 2026, with the latest reported value for each.

What the quarter means for a holding is a separate question from what it reported. The case for and against owning TMUS is on is TMUS a buy or a sell?, what analysts expect next is on the TMUS forecast, and what the company does is on the T-Mobile US (TMUS) stock page.

Every number on this page can be traced to a document T-Mobile US published. Checking one takes a couple of minutes, and it is worth doing before you quote a figure anywhere.

• The results release is the document linked in the source line above. Companies publish it on their investor relations site at the moment results go out, and it carries the headline tables: revenue, operating income, net income and EPS for the quarter and the year-ago quarter.
• The same release is filed with the SEC as Exhibit 99.1 to a Form 8-K under Item 2.02, usually on the day of the report. The SEC copy does not change after the fact, which makes it the safer thing to link when you cite a number.
• The quarterly report (Form 10-Q) follows within a few weeks and carries the full financial statements, the segment note and management's discussion of what changed. The fourth quarter is covered by the annual report (Form 10-K) instead.
• Restated comparisons are flagged in the notes on this page. When a company redraws its segments or changes how it adjusts EPS, it restates the year-ago column, so the year-ago figure in a new release can differ from the one printed a year ago. This page always uses the comparison in the newer release, because that is the like-for-like one.
