T-Mobile’s Cash Guide Rose, but Account Growth Slowed

T-Mobile’s reported growth remained strong, but its composition shifted. Total revenue increased 7.9% year over year to $22.79 billion, while service revenue rose 8.9% to $18.98 billion. Postpaid service revenue did better still, increasing 12.6% to $15.85 billion. Total revenue declined 1.4% sequentially, however, so Q2’s strength came from the recurring service base rather than broad-based quarter-over-quarter expansion. The Q2 FY2026 earnings release attributes the service-revenue performance to account growth and higher postpaid ARPA.

Monetization improved faster than customer acquisition. Postpaid ARPA reached $152.91, up 2.0% from $149.87 a year earlier and up from $151.93 in Q1. In contrast, postpaid net account additions fell to 277,000 from 318,000. Postpaid account churn rose seven basis points year over year to 0.99%, although it improved from 1.04% in Q1. The quarter therefore provided evidence that T-Mobile can extract more revenue from each account, but less evidence that its customer-acquisition engine is accelerating.

Profit and cash generation were positive. Net income increased only 0.5% to $3.24 billion, but diluted EPS rose 5.3% to $2.99, helped by a lower share count. The result included $0.14 per share of UScellular merger-related costs, including accelerated depreciation, net of tax. Core adjusted EBITDA rose 11.7% to $9.54 billion, materially faster than total revenue. The supplied pre-tax-margin proxy nevertheless declined to 24.1% from 24.7% a year ago, showing that adjusted operating progress did not translate perfectly into the supplied margin series.

Operating cash flow increased 7.3% to $7.50 billion. Capital expenditures rose 12.8% to $2.70 billion, leaving adjusted free cash flow of $4.80 billion, up 4.4%. Management raised FY2026 operating cash flow guidance to $28.4-$28.8 billion from $28.1-$28.7 billion and lifted adjusted free-cash-flow guidance to $18.4-$18.8 billion from $18.1-$18.7 billion. Both midpoints rose by $200 million. Guidance for 950,000-1.05 million postpaid net account additions and $37.1-$37.5 billion of Core Adjusted EBITDA was reiterated rather than increased.

The quarter strengthens the cash-conversion and service-revenue elements of the case. Service revenue grew faster than total revenue, and Core Adjusted EBITDA grew faster than both. That pattern is consistent with improved economics from a larger recurring customer base and higher ARPA. The increase in cash guidance is more important than the modest EPS beat against the prior-year quarter because it indicates that management expects the improvement to persist through the balance of FY2026.

The customer data are more mixed. T-Mobile reported a record wireless net promoter score of 46 and cited third-party network awards, but postpaid additions still declined and churn increased year over year. Those figures do not invalidate the differentiation argument, but they raise the standard for subsequent quarters. If account growth continues to slow, revenue growth will depend increasingly on ARPA, acquired customers and broadband or newer businesses. Pricing-led growth may be durable, but it can also invite stronger competitive responses.

Capital allocation remains meaningful. T-Mobile returned $3.3 billion during Q2, comprising $2.2 billion of repurchases and $1.1 billion of dividends. Since the program began in Q3 FY2022, cumulative returns reached $54.6 billion. Repurchases contributed to EPS growing faster than net income this quarter. They also have to be considered beside $86.28 billion of debt and only $2.83 billion of cash reported at quarter-end in the Q2 FY2026 Form 10-Q. That capital structure makes sustained operating cash generation more important than any single quarter’s adjusted earnings.

Overall, the print was incrementally bullish rather than thesis-changing. Cash guidance moved higher, recurring revenue growth remained strong and ARPA advanced. The offsets—slower account additions, higher churn, merger costs and a lower supplied margin proxy—argue against a large valuation increase.

There is no prior SageNoodle fair value to carry forward, so this update establishes an initial value rather than revising an earlier one. We use the supplied TTM EPS of $9.57 because management did not provide GAAP net-income or EPS guidance. The base case applies a 19.0x multiple, producing $181.83 per share, rounded to $182. That is a modest premium to the current 18.5x TTM P/E and reflects the raised cash outlook without assuming an undisclosed EPS forecast.

The bear case applies 14.0x TTM EPS for a value of $134. It assumes customer additions weaken further, churn remains elevated and debt or competition compresses the multiple. The bull case applies 23.0x for a value of $220, requiring sustained high-single-digit service-revenue growth, continued double-digit Core Adjusted EBITDA growth and visible progress on integration costs. These are valuation assumptions, not company guidance.

At the current price of $177.16, the $182 base value implies approximately 2.7% upside and a Fairly Valued verdict under SageNoodle’s thresholds. The snapshot EV/Core Adjusted EBITDA figure of 7.4x uses the supplied $191.8 billion market capitalization, quarter-end debt and cash, and the $37.3 billion midpoint of FY2026 Core Adjusted EBITDA guidance. It is supplementary; the primary valuation remains the explicit P/E framework because the requested financial-company convention prioritizes EPS, revenue, book capital and leverage.

The bullish interpretation would be wrong if service-revenue growth proves dependent on acquisition-related account additions or pricing that cannot be sustained. A continued decline in organic postpaid account additions, especially alongside churn above the prior-year level, would weaken the claim that network and customer-experience differentiation is widening.

The valuation would also be too high if adjusted measures overstate underlying progress. Q2 included UScellular merger-related costs, retail-initiative costs and other exclusions in the adjusted EBITDA reconciliation. Integration costs may be temporary, but repeated adjustments can delay the conversion of adjusted growth into GAAP earnings. The supplied pre-tax-margin proxy already moved lower year over year despite double-digit Core Adjusted EBITDA growth.

Leverage is the final constraint. Debt of $86.28 billion materially exceeds cash, while the company continues to invest in its network and return capital to shareholders. Higher funding costs, spectrum requirements, integration spending or more intense wireless and satellite competition could redirect cash away from repurchases and dividends. Conversely, sustained service growth, lower churn and cash generation above the raised guidance would make the 19.0x base multiple conservative.
