An examination of the quarterly financial metrics reveals several notable trends and fluctuations in revenue, costs, profitability, and expenses.

Revenue Trends

Postpaid revenues show a generally consistent upward trend over the periods observed, starting from 5,887 million US$ and advancing steadily to 14,882 million US$. This demonstrates sustained growth in the postpaid customer base or increased pricing power.

Prepaid revenues, however, maintain relative stability with minor fluctuations around the 2,300 to 2,700 million US$ range. This suggests a mature or saturated prepaid market segment without significant expansion.

Wholesale and other service revenues decline over time, dropping from a high of 1,708 million US$ to a low near 700 million US$, indicating decreased reliance or performance in this segment.

Overall service revenues increase consistently, reflecting the growth in the core customer offerings and possibly more value-added services.

Equipment revenues show volatility with periods of decline and recovery. Initial growth peaks around 5,973 million US$ before falling to lower levels near 3,000 to 4,000 million US$, indicating variable equipment sales volumes or pricing changes.

Other revenues remain relatively small and stable, with no significant upward or downward trajectory.

Aggregate revenues exhibit volatility, peaking at over 20,000 million US$ multiple times but also experiencing quarters of decline, reflecting the combined impacts of the segmented changes.

Cost Patterns

The cost of services exclusive of depreciation and amortization remains substantial but shows a slight decreasing trend over recent periods, falling from approximately 3,800 million US$ to below 2,700 million US$. This may reflect improved service delivery efficiency or cost-cutting measures.

Cost of equipment sales also shows fluctuations in line with equipment revenue changes, with spikes up to nearly 7,000 million US$ and troughs around 3,000 million US$. This volatility suggests inventory and sales cycle effects.

Total cost of revenues generally follows revenue trends but with some decoupling in quarters reflecting operational changes or margin management.

Profitability and Operating Results

Gross profit displays a solid upward trajectory, moving from 6,945 million US$ to beyond 14,000 million US$, indicating improving gross margin performance despite revenue fluctuations.

Operating income varies significantly but generally trends upward, reaching highs above 5,000 million US$ after initial quarters of lower results, reflecting better cost control and operational leverage.

The data show the presence of impairment expenses in sporadic quarters and a notable loss on disposal of certain groups which likely affected operating results temporarily.

Expenses

Selling, general and administrative expenses fluctuate but exhibit minor increases overall, suggesting stable investment in sales and administrative functions relative to revenue.

Depreciation and amortization expenses remain fairly stable with slight decreases, indicating steady investment in capital assets without significant new additions or disposals.

Interest expense remains consistently negative, with minor fluctuations around 800 to 900 million US$, implying steady debt servicing costs.

Income Metrics and Taxation

Income from continuing operations before taxes varies, showing recovery and growth in later periods to near 4,000 million US$, indicating improving operational profitability and financial health.

Income tax expense fluctuates significantly, with some quarters reflecting an income tax benefit, likely due to unusual or deferred tax items.

Net income mirrors operating trends but includes the effect of discontinued operations in one quarter, which temporarily boosted reported profit.

Overall net income increases over the time frame, evidencing growing profitability despite volatility in some quarters.

In summary, the company demonstrates growth in core revenues, especially postpaid service revenues, accompanied by improving gross profit margins and operating income. Despite some cost volatility, particularly in equipment sales and impairments, overall profitability improves. Expense management appears effective, maintaining stable administrative costs and controlled depreciation. Interest expenses show consistent debt servicing levels. Income tax impacts fluctuate, but net income grows steadily, denoting strengthening financial performance.
