// Full episode scriptWelcome to Beta Finch, your AI-powered earnings breakdown! I'm Alex.
And I'm Jordan. Today we're digging into T-Mobile's third quarter 2026 results, and spoiler alert — the Un-carrier is still flexing.
Before we get into it, quick disclaimer: this podcast is AI-generated content for educational and entertainment purposes only. Nothing we discuss should be considered investment advice. Always do your own research and consult a qualified financial advisor before making any investment decisions.
Solid. Now let's talk numbers, because T-Mobile dropped some pretty strong ones.
Right out of the gate — postpaid service revenue up 9% year-over-year, total service revenue up 6%, and core adjusted EBITDA up a whopping 11%. Adjusted free cash flow margin landed at 26%. That's just... a really healthy quarter.
And they led the industry — again — in postpaid phone net adds AND 5G broadband net adds. Postpaid account additions came in at 274,000, and postpaid ARPA — that's average revenue per account — grew over 4% year-over-year.
What's notable is they raised full-year guidance across the board. Service revenue guidance moved up to about $76.8 billion, roughly 8% growth for the year. Core adjusted EBITDA guide bumped up to $37.35 to $37.45 billion. And adjusted free cash flow is now expected between $18.7 and $18.8 billion.
They also raised postpaid ARPA growth guidance from 2.5-3% up to 3.5% for the year. That's driven by customers adopting premium rate plans — CFO Peter Osvaldik mentioned 60% of new accounts are choosing premium plans right out of the gate.
Let's talk strategy, because there's a lot of interesting stuff beyond the spreadsheet. First, leadership transition — Jessica Uhl is coming in as CFO-designate, replacing Peter Osvaldik in a planned succession. Chris Sambar is now Chief Enterprise Officer.
And then there's T-Mix — this new plan structure they just launched. The pitch is basically: stop forcing customers into rigid bundles. Let people pick the benefits they actually want and swap them when life changes. Apparently 84% of surveyed customers wanted more control over their plans, so this is T-Mobile trying to solve a real pain point before competitors do.
The other big theme — and I thought this was the most forward-looking part of the call — is "Physical AI." They're building something called Kinetic Edge with AWS, which combines their 5G Advanced network with cloud compute to support robots, drones, and other connected machines that need low-latency connectivity plus edge inference.
It's early days — CEO Srini Gopalan was pretty candid that they're not sure if the big infrastructure buildout happens in 2027, 2028, or later, but he's confident it happens by 2035. Right now, monetization isn't about selling connectivity or compute separately — it's bundled into full solutions, where T-Mobile essentially takes a cut from reducing the cost of the device itself.
They also completed what they're calling the world's first AI-RAN call in the real world, not a lab — testing AI-driven network optimization. Their Chief Technology Officer, John Saw, noted that spectral efficiency gains from AI were actually better than expected when they rolled it out live in New York.
Now let's get into some of the juicier Q&A moments. Analysts pushed hard on fixed wireless access — FWA. There's been chatter about Verizon decelerating there, so analysts wanted to know if T-Mobile was seeing the same thing.
And the answer was basically "no deceleration here." Management said they're tracking ahead of pace toward their goal of 15 million FWA customers by 2030, with ARPU growing both sequentially and year-over-year. They also leaned into NPS data showing their broadband — including versus fiber — has category-leading customer satisfaction.
There was also a fun exchange about SpaceX and satellite. An analyst asked if T-Mobile would ever consider an MVNO deal with SpaceX beyond the existing T-Satellite resale arrangement. Srini was pretty blunt — he doesn't see satellite as additive to their core FWA business because satellite has real constraints compared to their terrestrial network. Satellite stays a complementary, niche product, not a strategic pivot.
And on capital allocation — Peter Osvaldik flagged that 2027 and 2028 upcoming spectrum auctions, like C-band 2.0 and the 2.7 GHz band, are likely to eat up a bigger chunk of their capital envelope going forward, even as they continue buybacks — they've already done $10.3 billion in buybacks this year — and raised their dividend 15%.
One more interesting nugget — they addressed AI agents and whether tools like shopping bots could commoditize wireless plans and hurt pricing power. Their enterprise executive basically said bring it on — because T-Mobile's back-book-to-front-book pricing advantage means existing customers already pay less than new ones, so if AI agents start comparison shopping for people, that favors T-Mobile pulling customers in rather than losing them.
So what does all this mean for investors going forward?
Everything discussed is AI-generated analysis for educational purposes. Past performance doesn't guarantee future results. Please do your own due diligence.
With that said — the core takeaway here is a company executing consistently across multiple growth levers: wireless share gains, broadband expansion, enterprise wins like the DOJ wireless contract, and now early positioning in physical AI infrastructure. Guidance raises across revenue, EBITDA, and free cash flow suggest management has real confidence in the underlying momentum, even as they flagged some natural Q4 variability around device cycles and seasonal churn.
The spectrum auction commentary is probably worth watching closely heading into 2027 and 2028 — that's going to be a meaningful swing factor in how they allocate capital between buybacks, dividends, and network investment.
That's it for this episode of Beta Finch. Thanks for listening, and we'll catch you next time with another earnings breakdown.
