TMUS Q2 2026 Earnings Analysis

It really does, Alex. But before we get into it — this podcast is AI-generated content for educational and entertainment purposes only. Nothing we discuss should be considered investment advice.

And the headline stat that jumped out at me was their Net Promoter Score — 46, which they're calling the highest NPS in wireless history among the big three carriers. That's not just a vanity metric either, because it's translating directly into subscriber growth. They added 277,000 postpaid accounts in Q2.

What I found interesting is the postpaid ARPA story. Headline growth was 2%, which sounds a little soft compared to that 13% service revenue number. But Osvaldik explained that's a comp issue — last year's UScellular acquisition and the fiber joint venture brought in lower-ARPA customers. Strip out the M&A noise and ARPA actually grew 3.7% year-over-year. By the end of the call, he even said they're now tracking toward the higher end of their 2.5-to-3% full-year ARPA guidance.

Right, and management was upfront about why. They're doing a rate plan modernization in Q3 that's expected to temporarily bump up account churn — but they specifically noted it's concentrated in accounts with fewer lines, so phone churn impact should be much smaller. It's a deliberate, planned dip, not a demand problem. Speaking of churn, actually, postpaid phone churn came in at just 0.85% this quarter, down meaningfully year-over-year.

And they got a great question on this from an analyst worried that FWA is eating up too much network capacity. CTO John Saw pushed back pretty firmly, saying capacity is still several multiples of what they're actually using, and that AI traffic — which everyone's worried about — hasn't materially hit mobile networks yet because most AI workloads live in wireline data centers, not on phones.

That spectrum conversation was a big theme throughout the Q&A. Management was clearly excited but also cagey on specifics — Srini compared this moment to their earlier bet on 5G standalone, saying they see it as another chance to "cement network leadership" ahead of competitors. They're being deliberately vague on how much they'll spend, which makes sense given they haven't seen final auction details yet.

One thing worth noting for investors — Osvaldik was pretty clear that they're keeping some capital in reserve for those upcoming spectrum auctions, so buyback pace going forward may be a bit more measured and opportunistic rather than a steady quarterly number.

And on the broadband bundling question, T-Mobile pushed back on the way AT&T frames convergence stats — while AT&T cites 45% of internet customers also having wireless, T-Mobile's Chief Customer Experience Officer André argued that if you count multi-line and device bundles, their number is closer to 70%.

I'd say the core story is durable premium growth. Strong network perception is driving higher-value customers in the door, port-in ARPA is running about 20% above port-out ARPA, and CLVs are up double digits. The near-term wrinkle is that Q3 net adds will look weak because of the planned rate plan modernization — that's expected and shouldn't be mistaken for a demand slowdown. The bigger swing factor for 2027 and 2028 is going to be how they play the spectrum auctions and how much capital that requires.

Well said. T-Mobile heads into the back half of the year with strong momentum, a raised free cash flow outlook, and some big strategic bets on the horizon with spectrum. We'll be watching closely for updates as those auctions take shape.

See you then!
