The News: T-Mobile US (NASDAQ: TMUS) reported Q4 FY 2025 results. Revenue was $24.3 billion, up 11% year over year (YoY), versus consensus of $24.2 billion. Service revenue was $18.7 billion, up 10% YoY. Adjusted EBITDA was $8.5 billion, up 6.7% YoY. Diluted EPS was $1.9, down 27% YoY.

“T-Mobile is raising the bar on what customers, stockholders, and the industry can expect from the Un-carrier. T-Mobile has an unmatched combination of the Best Network, Best Value, and Best Customer Experiences,” said Srini Gopalan, CEO of T-Mobile. “Looking ahead, we see an extraordinary runway to further expand this differentiation—through sustained momentum in network perception, digital and AI-driven transformation, and our future-forward innovation in areas like 6G and advanced AI.”

T-Mobile Q4 FY 2025 Results Highlight Broadband and Digital Scale

Analyst Take: T-Mobile’s quarter underscores the company’s pivot to account-based value creation, pairing network leadership with digital and AI-driven experiences to expand customer relationships and ARPA. Broadband outperformance continues to validate the fallow-capacity model while fiber scale-up adds a complementary growth vector. Management’s AI-RAN and 6G roadmap seeks to position the network as a compute-aware fabric, reinforcing differentiation beyond throughput and coverage. With FY 2026 guidance reaffirming service revenue and Core Adjusted EBITDA growth, and a stepped-up buyback cadence, the setup suggests a measured but durable trajectory amid a competitive, more promotional market.

Account-Centric Growth and ARPA Expansion

Management is shifting external reporting from phone lines to total postpaid accounts and ARPA, aligning with how value is created, as over 90% of postpaid phone lines are on multi-line accounts. T-Mobile guides FY 2026 ARPA growth of 2.5%–3.0%, with 1.0%–1.5% from underlying ARPU expansion as customers choose premium plans and add services. Digital engagement continues to reduce friction and unlock cross-sell, with a 50% reduction in calls to care since 2021, T-Life has been installed over 100 million times, and approximately 24 million monthly active users. Nearly 75% of postpaid phone upgrades are now completed digitally, with a majority unassisted, indicating growing customer preference for self-serve transactions. This account-led motion, together with premium plan differentiation, supports steady ARPA lift even as promotional intensity cycles. Overall, account-centric reporting and digital scale should improve revenue visibility and quality of mix over time.

Broadband Momentum and 2030 Targets

Broadband added 558,000 net customers in Q4, including 495,000 5G fixed wireless and 63,000 fiber, reinforcing the category’s role in service revenue and ARPA expansion. The company raised its 2030 broadband targets to 15 million 5G fixed wireless and 3–4 million T-Fiber customers, supported by spectral efficiency gains, improved CPE, expanded eligibility, and product broadening. Management continues to emphasize the fallow-capacity model for durable FWA economics, with customers and usage both growing rapidly over the last two years, and average download speeds up more than 50% in that period. T-Mobile is extending broadband to business customers and deepening its presence in small town/rural America (SMRA), where network perception and NPS leadership are improving. Fiber remains complementary, with household passings targeted at 12–15 million by 2030 and meaningful first-year penetration where T-Fiber launches. Together, FWA scale and targeted fiber build-out present a diversified, accretive broadband mix.

AI-RAN, 6G, and Network-Led Innovation

T-Mobile is investing in AI-RAN and a next-gen RAN architecture with partners NVIDIA, Nokia, and Ericsson to enable concurrent telco and AI workloads at the edge. The company reports successful full-voice calls on NVIDIA platforms from both Nokia and Ericsson, with field trials expected to begin toward the end of FY 2026. Management frames 6G as a connective tissue for “physical AI,” evolving networks from moving bits to also processing tokens for real-time, kinetic interactions. The launch of Live Translate, a real-time AI translation service embedded directly on the network, highlights the near-term potential of AI-enhanced experiences across any device. This approach aims to extend differentiation from speed and coverage to intelligent, programmable experiences at scale. If executed, AI-RAN and 6G investments could broaden T-Mobile’s role in edge AI ecosystems.

Guidance and Final Thoughts

For FY 2026, T-Mobile expects total postpaid net account additions of 900,000 to 1.0 million and service revenue of about $77.0 billion; for FY 2027, service revenue is expected to be $80.5–$81.5 billion. Core Adjusted EBITDA is guided to $37.0–$37.5 billion in FY 2026 and $40.0–$41.0 billion in FY 2027, with adjusted free cash flow of $18.0–$18.7 billion in FY 2026 and $19.5–$20.5 billion in FY 2027. Management reiterated a leverage target of approximately 2.5x and guided capital expenditures to about $10.0 billion in FY 2026. The company plans to accelerate Q1 FY 2026 share repurchases to up to $5.0 billion within its remaining capital envelope through FY 2027. With digital scale, broadband expansion, and network-led AI initiatives, T-Mobile is positioned to sustain revenue growth and operating leverage despite a still-promotional market backdrop.
