The income statement reveals a complex financial performance over the five-year period. While total revenues experienced some volatility, they ultimately demonstrate an upward trajectory. Gross profit and operating income show significant improvement, particularly in the later years, driven by changes in the cost structure. Net income also reflects this positive trend, although it is impacted by fluctuations in income tax expense.

Revenue Analysis

Postpaid revenues consistently represent the largest portion of total revenues and exhibit steady growth throughout the period, increasing from US$42,562 million to US$57,932 million. Prepaid revenues remain relatively stable, fluctuating between US$9,733 million and US$10,497 million. A notable decline is observed in Wholesale and other service revenues, decreasing from US$6,074 million in 2021 to US$2,877 million in 2025. Total revenues decreased slightly in 2022 and 2023, before recovering and showing strong growth in 2024 and 2025.

Cost of Revenues and Gross Profit

Cost of revenues decreased significantly from 2021 to 2023, falling from US$-36,605 million to US$-30,188 million, before increasing again in 2024 and 2025. This reduction in cost of revenues, coupled with relatively stable revenues, contributed to a substantial increase in gross profit, which rose from US$43,513 million in 2021 to US$55,535 million in 2025. The gross profit margin improved considerably over the period.

Operating Expenses

Selling, general and administrative expenses remained relatively consistent between 2021 and 2023, fluctuating around US$-21 billion, before increasing to US$-23,470 million in 2025. Depreciation and amortization expenses also remained relatively stable, decreasing slightly from US$-16,383 million in 2021 to US$-13,508 million in 2025. The presence of Gain (loss) on disposal group held for sale and Impairment expense in 2022 and 2025, respectively, introduce some volatility to the operating income.

Profitability

Operating income experienced a dramatic increase from US$6,892 million in 2021 to US$18,279 million in 2025. This improvement is attributable to the combined effect of increased gross profit and relatively controlled operating expenses. Net income followed a similar trend, increasing from US$3,024 million in 2021 to US$10,992 million in 2025, despite fluctuations in income tax expense. Income tax expense increased significantly in 2022, 2023, and 2024, impacting net income in those years.

Other Income and Expenses

Interest expense remained relatively stable, fluctuating between US$-3,364 million and US$-3,774 million. Other expense, net, also remained consistent, while other income (expense), net, showed some volatility, with a negative impact in 2022 and 2025. These items had a relatively minor impact on overall profitability compared to the core revenue and cost components.

In summary, the financial performance demonstrates a positive trend in revenue growth, improved cost management, and increased profitability. The decline in wholesale revenues warrants further investigation, while the fluctuations in income tax expense should be monitored. The significant increase in operating income and net income suggests improved operational efficiency and financial health.
