The financial data reveals several key trends in the profitability and efficiency metrics over the six-year period under review.

Gross Profit Margin

The gross profit margin experienced slight fluctuations but remained relatively stable, starting at 11.2% in 2020 and showing a minor decrease in 2022 to 10.48%. Subsequently, it rebounded gradually, reaching 11.12% by 2025. This suggests that the company managed to maintain consistent control over its cost of goods sold relative to revenue.

Operating Profit Margin

Operating profit margin displayed a general upward trend, rising from 3.33% in 2020 to 3.85% in 2025. Although a minor dip occurred in 2023 to 3.41%, the overall improvement indicates enhanced operational efficiency or better management of operating expenses over time.

Net Profit Margin

Return on equity exhibited some volatility, beginning at 21.89% in 2020 and peaking at 31.19% in 2024 before settling to 27.77% in 2025. These variations may reflect changes in leverage, net income, or equity base, but the elevated ROE levels throughout indicate effective utilization of shareholders' equity.

The financial performance over the periods under review reveals notable trends in profitability and equity management. Net income attributable to the entity demonstrates a consistent upward trajectory, increasing steadily from 4002 million US dollars in 2020 to 8099 million US dollars in 2025. This represents more than a doubling of net income over the six-year span, indicating strong growth in profitability.

Total stockholders’ equity exhibits some variability but an overall increasing pattern. Equity decreased slightly from 18284 million US dollars in 2020 to 17564 million in 2021, before rebounding sharply to reach 29164 million in 2025, the highest level within the timeframe. This suggests that while there may have been some fluctuations, the company has generally enhanced its capital base, possibly through retained earnings or equity issuances outpacing distributions.

The return on equity (ROE) metric, which measures profitability relative to shareholders’ equity, reflects fluctuations within a relatively narrow band. Starting at 21.89% in 2020, ROE peaked at 31.19% in 2024, before moderating to 27.77% in 2025. This volatility in ROE is consistent with the changes in equity levels and indicates effective—but varying over time—utilization of shareholders’ capital to generate profit.

Net Income
Consistent and robust growth from 4002 million US dollars in 2020 to 8099 million in 2025, indicating strong earnings performance.
Total Stockholders’ Equity
Saw a dip in 2021 but subsequently increased substantially, culminating in an equity base of 29164 million US dollars in 2025.
Return on Equity (ROE)
Fluctuated between approximately 22% and 31%, reflecting variable but generally effective deployment of equity capital.

Overall, the data points to a company exhibiting solid earnings growth and a strengthening capital position, with ROE levels suggesting a well-managed balance between profit generation and equity utilization. The improvement in net income outpaces that of equity growth, contributing to generally healthy returns for shareholders over the analyzed time frame.
