Q: Craig Moffett asked about FWA momentum compared to peers and requested the postpaid phone churn figure.

A: Srini Gopalan stated FWA momentum remains strong and ahead of the 15 million customer goal for 2030, while Peter Osvaldik noted the company is focused on account net additions rather than specific phone churn figures.

Q: Kutgun Maral asked about the monetization model for Physical AI and the impact of spectral efficiency gains.

A: Srini Gopalan explained that monetization focuses on selling complete solutions rather than just connectivity, while John Saw noted that AI-driven spectral efficiency gains are exceeding expectations and aiding capacity planning.

Q: Chaten asked about 2030 traffic profiles and potential capacity constraints.

A: John Saw stated the network is planning for increased uplink demand driven by AI and 6G, noting that 5G Advanced features are being deployed to manage these requirements.

Q: Sam McHugh asked about the potential for an MVNO relationship with SpaceX.

A: Srini Gopalan clarified that there is no room for an MVNO with SpaceX, as satellite is viewed as a complementary product rather than a core MVNO opportunity.

Q: Kannan Venkateshwar asked if the company's stance on satellite MVNOs was a specific pushback or a broader philosophical position.

A: Srini Gopalan reiterated that the company does not see synergistic opportunities for an MVNO with satellite providers, maintaining a consistent philosophy on when to engage in such deals.

Q: Sean Diffley asked about the competitive environment for Q4 and the pacing of buybacks versus spectrum acquisition.

A: Srini Gopalan noted Q4 will have variability due to device pricing and launches, while Peter Osvaldik stated that future capital allocation will increasingly prioritize upcoming spectrum auctions in 2027 and 2028.

Q: Peter Supino asked how the company reconciles its leading spectrum position with its appetite for future auctions.

A: Srini Gopalan explained that interest in auctions is driven by a rigorous buy-versus-densify analysis and the need to maintain network leadership, without paying uneconomic prices.

Q: John Hodulik asked about the implied slowdown in EBITDA and account growth in Q4 guidance and churn trends.

A: Peter Osvaldik explained that Q4 is seasonally promotionally intensive and noted that churn is expected to follow seasonal patterns, while emphasizing the company's 7% organic postpaid service revenue growth expectation.

Q: Sebastiano Petti asked if there is residual upward pressure on churn from rate plan modernization in Q4.

A: Peter Osvaldik confirmed that while Q4 churn includes seasonal factors, there is a minor residual impact from rate plan optimization that is already contemplated in the guidance.

Q: Kannan Venkateshwar asked about the trajectory of ARPA growth and the impact of subscriber mix.

A: Peter Osvaldik stated that ARPA growth is driven by the adoption of premium rate plans and deepening account relationships rather than just subscriber mix.

Q: Michael Rollins asked about the impact of AI agents on revenue and the 3-year equipment cycle.

A: Srini Gopalan said 36 months remains the right duration for device cycles, and Jon Freier added that the company has not seen significant impact from AI agents yet.

Q: Michael Ng asked about cost and digital initiatives and the outlook for wholesale and prepaid.

A: Srini Gopalan highlighted that AI and digital transformation are reducing care volumes, while Peter Osvaldik noted that wholesale revenue is facing a drag from the faster roll-off of TracFone and Boost.

Q: Sebastiano Petti asked if the company's view on fiber M&A or on-balance sheet investment has changed.

A: Srini Gopalan stated that fiber is viewed as a standalone business based on return on equity, and the company will not chase home-passed targets without rigorous economic justification.
