The financial performance, as indicated by the two-component DuPont analysis, reveals a generally positive trend in Return on Equity (ROE) over the observed period. This increase in ROE is primarily driven by improvements in Return on Assets (ROA), with Financial Leverage exhibiting a more stable pattern.

Return on Assets (ROA)
ROA demonstrates a clear upward trajectory. Starting at 12.02% in March 2022, it experienced a slight decline through the end of 2022, bottoming out at 10.19%. However, a consistent increase is then observed, culminating in 13.96% by December 2025. This suggests improving efficiency in asset utilization and profitability. The most significant gains occurred between December 2023 and September 2025, indicating a potentially impactful shift in operational performance during that timeframe.
Financial Leverage
Financial Leverage remained relatively stable throughout the period, fluctuating within a narrow range of 1.13 to 1.17. A slight increasing trend is visible from March 2022 to December 2022, followed by a modest decrease to 1.13 by March 2024. It then shows a slight increase again, reaching 1.15 by December 2025. This indicates a consistent, moderate use of debt financing, without significant changes in the company’s capital structure. The stability suggests a deliberate approach to managing financial risk.
Return on Equity (ROE)
ROE initially decreased from 13.58% in March 2022 to 11.93% in June 2022, mirroring the initial decline in ROA. It then stabilized before experiencing a consistent rise, reaching 16.02% by December 2025. The increase in ROE is directly correlated with the improvement in ROA, as Financial Leverage remained relatively constant. The positive correlation between ROA and ROE highlights the importance of asset efficiency in driving shareholder returns. The largest increase in ROE occurred between December 2023 and December 2025, coinciding with the most substantial gains in ROA.

In summary, the analysis indicates that the company’s increasing ROE is primarily attributable to enhanced asset utilization and profitability, as evidenced by the upward trend in ROA. The consistent Financial Leverage suggests a stable capital structure and a measured approach to debt financing. The observed patterns suggest a strengthening financial position and improving efficiency over the analyzed period.

The three-component DuPont analysis reveals a generally positive trend in Return on Equity (ROE) over the observed period, though with some fluctuations. Initial declines in ROE from March 2022 to December 2022 were subsequently reversed, and a continued upward trajectory is evident through December 2025. This overall improvement appears to be driven by a combination of factors related to profitability, asset utilization, and financial leverage.

Net Profit Margin
The Net Profit Margin demonstrates a clear upward trend, beginning at 27.84% in March 2022 and reaching 28.38% by December 2025. There was an initial decline from March 2022 to December 2022, bottoming out at 21.25%, but the margin has consistently increased thereafter, with peaks of 28.51% in September 2024 and 28.58% in September 2025. This suggests improving operational efficiency and/or pricing power.
Asset Turnover
Asset Turnover exhibits a more moderate pattern. It increased from 0.43 in March 2022 to a peak of 0.49 in March 2023, then experienced a slight decline to 0.46 in December 2023. A subsequent increase to 0.50 in September 2025 is observed, indicating improved efficiency in utilizing assets to generate sales. However, the fluctuations are less pronounced than those seen in the Net Profit Margin.
Financial Leverage
Financial Leverage shows a gradual increase from 1.13 in March 2022 to 1.17 in December 2022, followed by a slight decrease to 1.13 in March 2024. It then trends upward again, reaching 1.15 by December 2025. This indicates a moderate increase in the use of debt financing, which amplifies the impact of profitability on ROE. The changes in leverage are relatively small compared to the changes in profit margin.

The increase in ROE from 11.98% in December 2022 to 16.02% in December 2025 is attributable to the combined effect of improvements in all three components. The most significant driver appears to be the substantial increase in Net Profit Margin, followed by modest gains in both Asset Turnover and Financial Leverage. The period between March 2022 and December 2022 shows a decline in ROE, primarily driven by the decrease in Net Profit Margin, despite increases in Asset Turnover and Financial Leverage. The consistent improvement in profitability from 2023 onwards is a key factor in the overall positive trend in ROE.

The financial performance, as indicated by the two-component DuPont analysis, reveals a generally positive trend in profitability and efficiency over the observed period. Return on Assets (ROA) demonstrates an overall increase, driven by fluctuations in both Net Profit Margin and Asset Turnover. A detailed examination of each component follows.

Net Profit Margin
The Net Profit Margin exhibited volatility initially, decreasing from 27.84% in March 2022 to 21.25% in December 2022. However, a consistent upward trend is apparent from March 2023 onwards, culminating in 28.38% in December 2025. This suggests improving profitability, potentially due to enhanced pricing strategies, cost management, or a shift in product mix. The most significant increase occurred between September 2023 and December 2024, indicating a particularly strong performance during that timeframe.
Asset Turnover
Asset Turnover showed a gradual increase from 0.43 in March 2022 to a peak of 0.49 in both March 2023 and December 2025. There was a slight dip to 0.46 in December 2022 and again in September 2024, but these were relatively minor. The overall trend suggests increasing efficiency in utilizing assets to generate revenue. The increase from 0.46 in September 2024 to 0.49 in December 2025 coincides with the increase in Net Profit Margin, amplifying the positive impact on ROA.
Return on Assets (ROA)
ROA mirrored the combined effect of the two components. It began at 12.02% in March 2022 and experienced a decline to 10.05% by March 2023. Subsequently, ROA steadily increased, reaching 13.96% in December 2025. The most substantial gains in ROA occurred in the latter half of the period, particularly between September 2023 and December 2025, directly correlating with the improvements in both Net Profit Margin and Asset Turnover. The slight decrease in ROA from September 2025 to December 2025 is attributable to a minor decrease in Asset Turnover, despite the continued high Net Profit Margin.

In summary, the analysis indicates a strengthening financial position characterized by improving profitability and asset utilization. The consistent upward trend in ROA, driven by positive movements in both Net Profit Margin and Asset Turnover, suggests effective management strategies and a favorable business environment.
