Bottom line
The sleeper story here is that T-Mobile is engineering a stealth price increase through 'rate plan modernization' that will shed 250K accounts in Q3 but boost ARPA for everyone who stays, and the math suggests this is actually value accretive despite the headline churn. The market sees strong execution with 12% EBITDA growth, but the real constraint is network capacity: FWA is consuming 'a fair amount' of traffic and they're desperately excited about spectrum auctions to buy their way out of the coming capacity crunch. Osvaldik's quote about 'thoughtfully maintaining a capital envelope' for spectrum tells you buybacks are about to get squeezed. My view changes if they quantify actual network utilization rates or demonstrate AI revenue contribution beyond partnership press releases.

The 30-second version

  • The rate plan modernization is a stealth price hike that's working: Q3 will see 250k accounts churn but ARPAs tracking toward 3% growth
  • Fixed wireless is eating massive network capacity but management claims it's only using 'traffic' not 'capacity'
  • The spectrum auction excitement is code for 'we need to buy our way out of a capacity crunch'
