Material Changes vs. Prior Period

• Revenue Growth: Total revenues increased 7% year-over-year (YoY) for both the quarter and year-to-date (YTD). Postpaid revenues grew 9% (Q2) and 8% (YTD), driven by higher Average Revenue Per Account (ARPA) and account growth. Prepaid revenues grew 2% (Q2) and 6% (YTD), aided by the Ka'ena acquisition.
• Wholesale Decline: Wholesale and other service revenues decreased 24% (Q2) and 30% (YTD) due to lower MVNO revenues (including DISH and TracFone) and the impact of the Ka'ena acquisition, partially offset by higher advertising revenues from Vistar and Blis.
• Profitability: Operating income increased 13% (Q2) and 16% (YTD). Net income rose 10% (Q2) and 17% (YTD). The effective tax rate was 24.7% for Q2 2025 compared to 22.4% in Q2 2024.
• Customer Metrics: Total customers reached 132.8 million (up 5% YoY). Postpaid phone churn increased slightly to 0.90% (up 10 bps), attributed to rate plan optimizations. Postpaid ARPA increased 5% to $149.87.

Investor Verification Checklist

• Churn Trends: Monitor if postpaid phone churn stabilizes following the rate plan optimizations that caused a 10 bps increase in Q2.
• Wholesale Revenue: Assess the long-term impact of the Ka'ena acquisition on wholesale revenue streams and the offsetting growth from advertising (Vistar/Blis).
• Debt Servicing: Review the impact of new debt issuances ($7.8 billion net proceeds YTD) on interest expense and leverage ratios.
• Cybersecurity Liabilities: Track developments in regulatory inquiries regarding the 2021 and 2023 data breaches for potential additional fines or settlements.
