Moby Intelligence

4 min read

Performance was driven by a strategy of widening differentiation across network quality, value, and customer experience, resulting in an industry-leading Net Promoter Score (NPS) of 45.
Management attributed growth to capturing ‘network seekers,’ with recent switchers citing network quality as the primary reason for choosing T-Mobile for the first time.
The company is accelerating share gains in smaller markets and rural areas, where it currently holds a 24% household share, fueled by word-of-mouth and network expansion.
T-Mobile for Business is leveraging 5G Advanced network superiority to create new total addressable market (TAM) opportunities through advanced network solutions and cross-selling into traditional voice and broadband.
Broadband growth remains a key pillar, with the company positioning itself as the fastest-growing ISP by utilizing fallow wireless capacity for fixed wireless access (FWA).
Strategic positioning in fiber is focused on capital-efficient joint ventures that prioritize high internal rates of return (IRR) and local scale over broad ‘homes passed’ metrics.
Management highlighted a ‘double-digit advantage’ in back-book pricing compared to competitors, which supported a 3.9% growth in postpaid Average Revenue Per Account (ARPA).

The company raised its full-year guidance for postpaid net account additions and core adjusted EBITDA based on strong underlying business momentum.
Management is transitioning the network into a ‘connective tissue for physical AI,’ with plans to utilize fallow compute at the network edge to support low-latency robotics and humanoid robots.
The 2030 target of 15 million fixed wireless customers is based on a conservative model that assumes no additional spectrum acquisitions or 6G efficiency gains.
Retail strategy is shifting toward ‘experience stores’ which currently yield higher premium plan mixes and NPS scores, eventually leading to a smaller but more impactful physical footprint.
Guidance for Q2 ARPA growth assumes a temporary deceleration to approximately 2% due to year-over-year comparisons and the dilutive impact of recent acquisitions before reaccelerating in the second half.

Postpaid account churn increased more than line churn due to the mathematical weighting of broadband-only and new customers, who structurally churn at higher rates.
The company increased its 2026 stockholder return authorization by $3.6 billion, bringing the total program to $18.2 billion.
Management explicitly dismissed interest in acquiring legacy cable assets, stating a preference for attacking incumbents via fiber and FWA rather than becoming an incumbent.
The integration of UScellular is expected to be substantially complete by the end of 2026, with all new customer acquisitions already unified under the T-Mobile brand.
