Why did T-Mobile raise its 2025 guidance, and what does it exclude?

T-Mobile raised Core Adjusted EBITDA guidance by $100 million at both ends of the range, to $33.2–33.7 billion, and raised the midpoint of its operating cash flow and Adjusted Free Cash Flow guidance by $100 million, to $27.0–27.5 billion and $17.5–18.0 billion. The company did not disclose specific drivers in this filing. The guidance excludes the pending UScellular and Metronet acquisitions but includes recently incorporated Vistar Media, Blis and Lumos.

Is the strong cash flow growth sustainable, or is it an accounting effect?

Part of the increase is accounting-driven. Since November 1, 2024, cash proceeds from receivable sales are reported in operating cash flow rather than as investing inflows. The company says this change has no net impact on Adjusted Free Cash Flow. Capex decline of 7% to $2.5 billion was attributed to planned timing of purchases, so investors should expect some reversal in later quarters. Full-year guidance of about $9.5 billion in capex implies higher spending in the remaining quarters.

Are the subscriber trends a concern?

Postpaid phone net additions fell 37 thousand year-over-year and churn rose 5 basis points to 0.91%. Management attributes the increase primarily to temporary effects of current-year rate plan optimizations and to a growing base, partly offset by higher gross additions. Total postpaid net additions still rose year-over-year, driven by other connected devices and High Speed Internet, so investors may want to monitor whether churn normalizes.

How much leverage does T-Mobile carry, and how is it returning capital?

Total debt excluding tower obligations was $88.0 billion and net debt was $76.0 billion at quarter-end, with net debt to LTM Core Adjusted EBITDA at 2.3x. Short-term debt rose to $8.2 billion from $4.1 billion, and the company issued $7.8 billion of long-term debt in the quarter. Management targets a net debt to Core Adjusted EBITDA ratio of about 2.5x at year-end 2025 to fund pending acquisitions and spectrum transactions. In Q1 it repurchased $2.5 billion of stock and paid $1.0 billion in dividends under the $14.0 billion program that runs through December 2025.

T-Mobile US, Inc. 8-K: Earnings & Results

01—Abstract

Summary

Summary of the 8-K filed April 24, 2025. Cited figures are marked; the original filing is the authoritative source.

T-Mobile US (TMUS) reported Q1 2025 results that point to strong operating momentum.

Postpaid net customer additions were 1.337 million, the best Q1 ever, and postpaid phone net additions were 495 thousand, which the company says is the best in the industry. Service revenues rose 5% year-over-year to $16.9 billion^a, with postpaid service revenues up 8% to $13.6 billion. Net income grew 24% to $2.95 billion and diluted EPS rose 29% to $2.58, both reported as best-ever Q1 results.

Core Adjusted EBITDA increased 8% to $8.26 billion^b. Cash generation was the standout. Net cash from operating activities rose 35% to $6.8 billion, and Adjusted Free Cash Flow rose 31% to $4.4 billion.

Part of that improvement is accounting-driven: from November 1, 2024, receivable sale proceeds that were previously investing inflows are reported in operating cash flow, though the company states this has no net effect on Adjusted Free Cash Flow. Capital expenditures fell 7% to $2.5 billion^c, reflecting timing. Stockholder returns were $3.5 billion in the quarter, and cumulative returns since Q3 2022 reached $34.8 billion under a program authorizing up to $14.0 billion through December 2025.

The company raised its 2025 Core Adjusted EBITDA guidance to $33.2^d–33.7 billion, and modestly raised operating cash flow and Adjusted Free Cash Flow guidance. Postpaid net additions guidance of 5.5–6.0 million was held. Two factors warrant attention.

Postpaid phone churn rose to 0.91%, up 5 basis points year-over-year, which management attributes to temporary effects of rate plan optimizations. Total debt, excluding tower obligations, climbed to $88.0 billion as short-term debt rose sharply, and the guidance excludes the pending UScellular and Metronet acquisitions.
