The financial performance over the observed period is characterized by a divergence between stable gross profitability and declining operational efficiency. While the ability to manage direct production costs remained consistent, there was a systemic contraction in operating margins and returns on invested capital from early 2022 through 2026.

Margin Analysis
Gross profit margins remained exceptionally resilient, fluctuating within a narrow band between 84.55% and 87.18%. This indicates a sustained ability to maintain pricing power and control the cost of goods sold. However, the operating profit margin experienced a significant and prolonged decline, falling from a peak of 55.08% in March 2022 to a low of 24.32% by March 2026. This divergence suggests that operating expenses, such as research and development or administrative costs, grew at a rate that significantly outpaced revenue growth.
Net profit margins followed a similar downward trajectory, starting at 48.06% in March 2022 and stabilizing between 27% and 33% from 2024 through 2026. Despite the volatility, the company maintained a strong bottom-line percentage, though it is notably lower than the levels seen at the start of the period.
Return on Capital and Assets
Return on Equity (ROE) showed a sharp contraction, decreasing from 39.84% in March 2022 to a plateau ranging between 13% and 16% from 2024 onward. This decline reflects a reduction in the profitability generated relative to shareholders' equity.
Return on Assets (ROA) mirrored the ROE trend, dropping from 30.11% in March 2022 to approximately 10% to 12% in the subsequent years. The simultaneous decline in both ROA and ROE indicates a decrease in overall asset utilization efficiency and a reduction in the net income generated per unit of asset.
Period Trends and Stabilization
The data reveals three distinct phases: an initial period of high profitability (early 2022), a phase of rapid margin and return erosion (mid-2022 through 2024), and a subsequent period of stabilization (2025 through 2026). A slight recovery in operating profit margin is observed in the final quarter of 2026, rising to 28.79%, which may suggest a stabilization of operational costs or an increase in revenue efficiency.

The financial trajectory from March 2022 through September 2026 is characterized by a substantial expansion in both top-line revenue and absolute gross profit. Total revenues increased from US$ 2,965.1 million to US$ 5,115.8 million, while gross profit grew from US$ 2,560.2 million to US$ 4,542.2 million over the observed period.

Gross Profit Margin Trends
The gross profit margin demonstrated a high level of consistency, fluctuating within a narrow band between 84.55% and 87.18%. A peak margin of 87.18% was recorded in December 2022, representing the highest point of efficiency in cost of sales relative to revenue. Following this peak, the margin entered a period of gradual normalization, generally stabilizing between 85% and 86% throughout 2023, 2024, and 2025.
Correlation Between Volume and Profitability
Growth in gross profit was driven primarily by increased sales volume rather than margin expansion. While total revenues grew significantly, the gross profit margin remained relatively flat, indicating that the cost of goods sold scaled proportionally with the increase in revenue. This suggests a stable pricing environment and consistent production costs over the long term.
Short-term Volatility and Recovery
A temporary contraction in profitability is observed in the first quarter of 2026, where the gross profit margin declined to 84.55%. This represents the lowest margin within the analyzed period. However, a recovery trend followed immediately, with margins rising to 84.86% in June 2026 and further improving to 85.77% by September 2026, coinciding with the period's highest quarterly revenue of US$ 5,115.8 million.

= 100 × (2,048,200 + 1,293,500 + 642,900 + 879,900) ÷ (5,115,800 + 4,290,700 + 3,605,400 + 3,884,300) = 28.79%

A prolonged contraction in the operating profit margin is evident from early 2022 through the first quarter of 2026, followed by a notable reversal in the latter half of 2026. While total revenues maintained a general growth trend, the efficiency of converting those revenues into operating profit diminished consistently for over four years.

Operating Profit Margin Erosion
The operating profit margin experienced a significant and sustained decline, falling from a peak of 55.08% in March 2022 to a low of 24.32% by March 2026. This downward trajectory was characterized by a steady erosion of profitability, with margins dropping below the 30% threshold in March 2024 and remaining suppressed for several consecutive quarters.
Revenue and Operating Income Divergence
Revenues increased from 2.965 billion USD in March 2022 to 5.115 billion USD by September 2026. However, income from operations did not scale proportionally during the mid-period. Operating income reached a trough of 591.7 million USD in March 2025; at this point, revenues were higher than those recorded in early 2022, indicating that operating expenses grew at a rate that significantly outpaced revenue growth.
Profitability Recovery in 2026
A sharp recovery in operational efficiency is observed starting in mid-2026. Income from operations rose from 642.9 million USD in December 2025 to 2.048 billion USD by September 2026. This surge resulted in the operating profit margin climbing to 28.79% in the final analyzed quarter, effectively breaking the multi-year downward trend and suggesting a pivot in cost management or a significant increase in high-margin revenue streams.

The quarterly analysis of profitability indicates a significant long-term compression in net profit margins despite a substantial increase in overall revenues. Between March 2022 and September 2026, the net profit margin experienced a general downward trajectory, transitioning from a peak of 48.06% to a closing value of 28.51%.

Initial Margin Contraction
A sharp decline in profitability is observed during the first year of the analyzed period. The net profit margin fell from 48.06% in March 2022 to 33.81% by March 2023. This period represents the most aggressive contraction in the margin, suggesting a rapid increase in operating costs or a shift in product mix that disproportionately affected the bottom line relative to revenue growth.
Phase of Relative Stability
From March 2023 through December 2025, the net profit margin entered a period of relative stabilization, fluctuating within a narrow band between approximately 29% and 34%. During this window, the margin reached a local floor of 29.45% in March 2024 before experiencing minor recoveries, such as the 33.61% observed in September 2024. This indicates a period where cost management aligned more closely with revenue expansion.
Revenue and Net Income Divergence
A divergence is evident between top-line growth and profit efficiency. Revenues grew from 2.97 billion USD in March 2022 to 5.12 billion USD by September 2026. While net income also increased—rising from 973.5 million USD to 1.95 billion USD in the same period—the growth rate of expenses outpaced the growth rate of income, leading to the overall reduction in the net profit margin percentage.
Recent Performance Trends
The most recent data points from 2026 show a continued struggle to maintain higher margins. After a dip to 27.86% in June 2026, a slight recovery to 28.51% was noted in September 2026. Despite the record high quarterly revenue of 5.12 billion USD in the final period, the profit margin remains significantly below the levels seen in 2022, confirming a structural shift in the company's profitability profile.

Analysis of profitability metrics reveals a significant long-term compression in the Return on Equity (ROE), which declined from a peak of 39.84% in the first quarter of 2022 to a range between 13.65% and 15.87% by the final quarters of the analyzed period.

ROE Trajectory
A sharp downward trend occurred between March 2022 and March 2024, during which ROE fell from 39.84% to 14.29%. Following this period of rapid contraction, the ratio entered a phase of relative stabilization, fluctuating narrowly between approximately 13% and 16% through September 2026.
Equity Expansion
Stockholders' equity exhibited consistent and linear growth, increasing from 19.9 billion in March 2022 to 33.5 billion by September 2026. This steady expansion of the equity base acted as a primary driver in the reduction of the ROE percentage, as the capital base grew more rapidly than the corresponding net income.
Net Income Volatility
Net income displayed significant quarterly volatility, characterized by periodic peaks and troughs. The highest quarterly net income was recorded in September 2026 at 1.9 billion. While net income showed an overall upward trend in its peak values, the quarterly fluctuations prevented a consistent recovery of the ROE ratio.
Capital Efficiency and Stabilization
The inverse relationship between the growing equity base and the declining ROE suggests a dilution of equity efficiency as the company accumulated more capital. However, the stabilization of ROE observed from 2024 onward indicates that the company reached a new equilibrium where net income growth began to better align with the expanded scale of the equity base.

1 Q3 2026 Calculation
ROA = 100 × (Net incomeQ3 2026 + Net incomeQ2 2026 + Net incomeQ1 2026 + Net incomeQ4 2025) ÷ Total assets
= 100 × (1,948,700 + 1,296,900 + 727,200 + 844,600) ÷ 44,405,200 = 10.85%

The financial data reveals a sustained expansion of the asset base accompanied by a significant compression in the Return on Assets (ROA) over the period from March 2022 to September 2026. While the company successfully scaled its total assets, the efficiency of these assets in generating net income has diminished significantly from the initial reporting period.

Asset Base Expansion
Total assets demonstrated a consistent and aggressive upward trajectory, growing from 26.35 billion USD in March 2022 to 44.41 billion USD by September 2026. This represents a steady increase in the company's resource base, with the most significant growth occurring between March 2024 and September 2026.
Net Income Volatility
Net income exhibited substantial quarterly fluctuations rather than a linear growth pattern. Earnings peaked at 1.95 billion USD in September 2026, but the period was marked by several troughs, including a low of 722 million USD in March 2024. This volatility suggests that profitability is subject to periodic variances that do not mirror the steady growth of the balance sheet.
ROA Trend Analysis
The Return on Assets experienced a sharp decline during the 2022 calendar year, dropping from a high of 30.11% in March to 14.85% by December. Following this initial contraction, the ROA entered a phase of relative stabilization, fluctuating within a narrower range between 10% and 14% from 2023 through 2026. The final recorded ROA of 10.85% indicates a long-term downward trend in asset productivity.
Correlation Between Growth and Efficiency
An inverse relationship is observed between the growth of total assets and the ROA percentage. The continuous increase in the asset denominator, paired with non-linear growth in the net income numerator, has led to a dilution of the ROA. This pattern suggests that the capital investments and asset acquisitions made during this period have not yet yielded a proportional increase in quarterly net earnings.
