Revenue Composition
Postpaid revenues consistently represented the largest portion of total revenues, increasing from 52.14% in March 2021 to 67.78% in September 2025, before decreasing to 63.20% in December 2025.

Wholesale and other service revenues exhibited a consistent downward trend, decreasing from 7.78% to 3.03% over the observed period. Consequently, equipment revenues decreased from 27.06% to 22.04% before increasing to 28.63% in December 2025. Other revenues remained a small, relatively stable percentage of total revenues.
Cost of Revenues and Gross Profit
The cost of revenues, as a percentage of revenues, generally decreased from 43.15% in March 2021 to 40.17% in December 2022, then increased to 42.21% in December 2025. This movement corresponded with fluctuations in gross profit, which rose from 56.85% in March 2021 to a peak of 63.51% in June 2023, before decreasing to 57.79% in December 2025. The largest decrease in gross profit occurred between December 2021 and March 2022.
Operating Expenses

Depreciation and amortization decreased steadily from 21.71% to 14.40% over the period. Impairment expense and gains/losses on disposal groups were infrequent and had a minimal impact on overall results. Other expense, net, remained relatively stable, fluctuating between 3.42% and 4.86%.
Operating and Net Income
Operating income demonstrated significant variability, increasing from 10.83% in March 2021 to a peak of 24.67% in June 2025, before decreasing to 15.35% in December 2025. Interest expense, net, remained relatively stable, fluctuating between 3.85% and 4.49%. Income from continuing operations before income taxes followed a similar trend to operating income, peaking at 20.25% in June 2025 and decreasing to 10.83% in December 2025. The effective tax rate fluctuated, resulting in net income ranging from 4.72% to 15.25% of revenues. Net income peaked in June 2025 at 15.25% before decreasing to 8.64% in December 2025.

In summary, the period witnessed a shift in revenue mix towards postpaid services, coupled with fluctuating profitability influenced by cost of revenues and operating expenses. While operating income showed an overall upward trend until mid-2025, it experienced a decline in the latter part of the observed period, impacting net income.
