T-Mobile US Q1 Earnings Call Highlights

Key Points

• T‑Mobile posted strong Q1 financials — postpaid service revenue +15% YoY, total service revenue +11%, core adjusted EBITDA +12% — returned $6 billion to shareholders and raised full‑year guidance (postpaid net additions now 950k–1,050k, core EBITDA to $37.1B–$37.5B).
• Customer momentum is robust with an industry‑leading NPS of 45, postpaid net adds of 217,000 and over 500,000 broadband net additions in Q1, driving share gains in both urban and rural markets.
• Strategic investments emphasize network and edge capabilities: T‑Mobile expects to invest about $2.7 billion across two fiber JVs to acquire regional ISPs, while advancing 5G Advanced and network‑native AI (beta live translation and early work with Figure AI humanoid robots) for edge inferencing.

T-Mobile US NASDAQ: TMUS executives touted what President and CEO Srini Gopalan called an “extraordinary” start to 2026, pointing to strong customer growth, rising service revenue and an increase in several elements of full-year guidance. On the company’s first-quarter earnings call, leadership emphasized that T-Mobile’s strategy—centered on “best network, best value, and best experience”—is widening differentiation and driving both subscriber momentum and profitability.

Customer momentum and network-led switching

Gopalan said T-Mobile’s Net Promoter Score reached 45, which he described as “industry-leading” and “over 20% higher” than the next closest competitor. He highlighted an opportunity among “20 million-plus families and businesses who are network seekers not currently with T-Mobile,” adding that among recent switchers, the highest percentage ever reported that they chose T-Mobile for network quality.

The company reported postpaid net account additions of 217,000 in Q1, up 6% year-over-year, according to Gopalan. He also said T-Mobile grew its share of postpaid households across cohorts in the top 100 cities and continues to gain in smaller markets and rural areas, where he cited a 24% household share.

On competition, Gopalan said the market can “over-rotate on promotions,” arguing that “the direction of flow gets driven by differentiation.” He noted January was “particularly competitive” and subsidy-driven, with “some cooling down” in February, March, and into April. Chief Business and Product Officer Mike Katz echoed that emphasis, saying T-Mobile focuses on proving value “every single day” rather than at phone replacement time, and cited “$3,800” in savings over five years versus competitors as part of the company’s value message.

Broadband growth and fiber joint ventures

Gopalan said T-Mobile added over 500,000 total broadband net additions in the quarter, calling the company the “fastest-growing ISP in the U.S.” He added that 5G broadband net additions accelerated year-over-year and said the product leads on customer experience rankings across multiple third-party sources, while 5G broadband speeds are “over 50% faster than the next closest competitor.”

In fiber, Gopalan said the company is pursuing a “returns-focused, capital-efficient approach.” He pointed to an announcement that T-Mobile is entering into “two additional JVs with leading infrastructure partners to acquire GoNetspeed, Greenlight Networks, and i3 Broadband.”

Addressing valuation and deal appetite, Gopalan told BNP Paribas Exane analyst Sam McHugh that T-Mobile views fiber as an “equity value creation opportunity” rather than “the myth of convergence,” and evaluates assets based on whether they can deliver targeted “double-digit” internal rates of return. He said the company is not chasing a “homes passed” figure for its own sake.

In response to Barclays analyst Kannan Venkateshwar, Gopalan said scale in fiber depends on “a national brand and local scale,” including permitting and local execution. He added the company is not interested in cable, saying, “We see our strength as attacking incumbents rather than becoming an incumbent.”

On the new JVs, CFO Peter Osvaldik said T-Mobile’s investment is expected to be “about $2.7 billion” across the two ventures when they close, with additional details to come after closing.

ARPA growth, churn commentary, and pricing philosophy

Gopalan said the company delivered postpaid ARPA growth of 3.9% in Q1, attributing performance to a “double-digit advantage in backbook pricing” versus leading competitors and customer relationship deepening. Osvaldik said ARPA growth reflected multiple factors including prior “rate plan optimizations,” increased lines per account, and continued mix shift toward higher-tier plans. He said “over 60%” of new account lines are selecting premium tier rate plans.

On churn, Gopalan said postpaid phone churn was “pretty stable,” up about 3 basis points. He explained the newly reported postpaid account churn metric is structurally higher than line churn because two cohorts—newer customers and broadband-only customers—tend to churn more and carry heavier weight in accounts than in lines. He added that account churn has risen more than line churn largely because broadband is the fastest-growing business and has higher churn than wireless.

When asked about longer-term pricing, Gopalan said T-Mobile evaluates pricing through ARPA growth rather than seeking “parity” through a single adjustment. He emphasized the company intends to “protect our position on best value” and described T-Mobile’s approach as typically “more for more” updates that modernize older plans, sometimes with price changes, rather than “whack that pricing up.”

AI, 5G Advanced, and physical AI at the edge

Gopalan previewed a beta rollout of “live translation,” which he called the company’s “first network-native AI application,” translating voice into “one of 80 different languages” using models embedded in T-Mobile’s core network. He also announced that T-Mobile is connecting its “5G Advanced network to Figure AI’s Figure 03 humanoid robots,” describing it as an early step toward supporting “physical AI” and edge inferencing.

CTO John Saw said T-Mobile is “highly optimistic” about physical AI and argued the company’s nationwide 5G Advanced deployment provides an advantage. He said 5G Advanced innovations that improve spectral efficiency and capacity—particularly on uplink—support physical AI use cases, and asserted T-Mobile has a “multi-year advantage” in enabling “edge inferencing for physical AI.”

Financial results, guidance raises, and shareholder returns

Gopalan said Q1 featured postpaid service revenue growth of 15% year-over-year and total service revenue growth of 11%. He said core adjusted EBITDA rose 12% year-over-year, while free cash flow margins were 24%. He also said T-Mobile returned $6 billion to shareholders through dividends and buybacks during the quarter.

Osvaldik said management is increasing guidance across “multiple fronts,” including:

• Total postpaid net account additions now expected between 950,000 and 1,050,000.
• Full-year service revenue still expected at approximately $77 billion (about 8% growth), with Q2 service revenue expected around $19 billion (up 9% year-over-year).
• Full-year postpaid ARPA growth still expected at 2.5% to 3%.
• Core adjusted EBITDA guidance raised to $37.1 billion to $37.5 billion, with Q2 expected around $9.4 billion (up 10% year-over-year).
• Cash CapEx unchanged at approximately $10 billion.
• Adjusted free cash flow guidance raised to $18.1 billion to $18.7 billion.

Osvaldik also noted that T-Mobile increased its 2026 shareholder return authorization by up to $3.6 billion, bringing the total authorization up to $18.2 billion. In Q&A, he said the company will continue to follow its capital allocation framework and evaluates repurchases based on perceived discount to intrinsic value.

On cost synergies, Osvaldik said progress toward the company’s synergy plan is “going really well,” stating its target (which he referenced as “exiting 2027”) remains on track, with much of the benefit expected “towards the last part of 2026” and into 2027. He cited progress in areas such as an AI-powered chatbot, which he said is containing “about 60%” of customer questions it receives.

Separately, Gopalan declined to comment on merger rumors involving Deutsche Telekom, but said that hypothetically, a transaction like the one referenced by an analyst would require “a separate approval process by disinterested shareholders,” often described as a “majority of the minority” vote.
