The analysis of the presented financial metrics reveals significant fluctuations in Return on Equity (ROE) driven by changes in Return on Assets (ROA) and Financial Leverage. A period of relative stability from March 2022 to December 2022 is followed by a marked shift in performance beginning in March 2023, culminating in substantial increases through December 2025.

Return on Assets (ROA)

ROA demonstrates a generally declining trend from 7.16% in March 2022 to a low of 0.23% in September 2024. This decline is particularly pronounced in the latter half of 2023 and the first three quarters of 2024. However, a strong recovery is observed from March 2025, with ROA increasing to 10.57% and continuing to 14.42% by December 2025. The initial period shows ROA values between 5.33% and 9.02%, indicating moderate asset utilization efficiency. The dramatic drop and subsequent rebound suggest significant operational or investment shifts impacting asset profitability.

Financial Leverage

Financial Leverage exhibits a moderate decrease from 3.17 in March 2022 to 2.60 in December 2025. The decline is relatively consistent, though not linear, suggesting a gradual reduction in the reliance on debt financing. Values remain above 2.7 throughout most of the observed period, indicating a continued, though diminishing, use of leverage. The increase to 3.21 in March 2024 is a notable deviation from the overall downward trend, potentially reflecting a temporary increase in debt levels.

Return on Equity (ROE)

ROE mirrors the trends observed in ROA, initially declining from 22.66% in March 2022 to 15.82% in December 2022. A subsequent increase is seen through December 2023, peaking at 26.59% in March 2023. However, ROE experiences a substantial drop in the first half of 2024, reaching a low of 0.69% in September 2024. The recovery observed in ROA is strongly reflected in ROE, with values increasing significantly to 31.13% in March 2025 and reaching 37.65% in September 2025, before stabilizing at 37.48% in December 2025. The magnitude of ROE fluctuations highlights the sensitivity of equity returns to changes in both asset profitability and financial leverage.

ROE Disaggregation

The two-component disaggregation of ROE demonstrates that the fluctuations in ROE are primarily driven by changes in ROA. While Financial Leverage exhibits a gradual decline, its impact on ROE is less pronounced than the significant swings in ROA. The sharp decline in ROE during the first half of 2024 is directly attributable to the corresponding drop in ROA. Conversely, the substantial increase in ROE from March 2025 onwards is largely a result of the ROA recovery. This suggests that the company’s ability to generate profits from its assets is the key determinant of shareholder returns.

In conclusion, the period under review is characterized by a significant shift in financial performance. While financial leverage has decreased modestly, the primary driver of ROE fluctuations is the substantial volatility in ROA. The recent recovery in ROA and subsequent increase in ROE suggest a positive trend, but the earlier period of decline warrants further investigation.

The three-component DuPont analysis reveals significant fluctuations in Return on Equity (ROE) over the observed period. These fluctuations are driven by changes in Net Profit Margin, Asset Turnover, and Financial Leverage. A notable shift in performance is evident when comparing the earlier periods (March 2022 – December 2022) to the later periods (March 2023 – December 2025).

Net Profit Margin

The Net Profit Margin demonstrated variability. From March 2022 to September 2022, a decline from 16.60% to 12.44% was observed, followed by a recovery to 17.02% by December 2022. The margin then increased steadily through September 2023, reaching 21.60%, and continued to rise through December 2023 (21.03%). A dramatic decrease occurred in the subsequent periods, falling to 1.78% by March 2024, before experiencing some recovery, but remaining substantially lower than prior levels. A strong resurgence is then seen from March 2025 onwards, peaking at 29.43% by December 2025.

Asset Turnover

Asset Turnover remained relatively stable between March 2022 and December 2022, consistently around 0.43. A slight increase to 0.44 was noted in June and September 2023, before returning to 0.43 in December 2023. From March 2024, the ratio increased to 0.48 and 0.52, before decreasing again to 0.49 and 0.49 in September and December 2025, respectively. The changes in this ratio appear less pronounced than those observed in the Net Profit Margin.

Financial Leverage

Financial Leverage exhibited a gradual decline from 3.17 in March 2022 to 2.72 in December 2022. This downward trend continued into 2023, reaching 2.60 by December 2023. A reversal occurred in March 2024, with leverage increasing to 3.21, followed by a decrease to 2.95 by September 2024. The ratio continued to decline through December 2025, reaching 2.60.

Return on Equity (ROE)

ROE mirrored the fluctuations in its component ratios. It decreased from 22.66% in March 2022 to 15.82% in September 2022, then recovered to 21.62% by December 2022. ROE increased significantly through September 2023, reaching 26.33%, and remained relatively high through December 2023 (24.81%). A substantial decline was then observed, with ROE falling to 2.77% by March 2024. The ratio then experienced a significant recovery, increasing to 37.65% by September 2025 and remaining at 37.48% by December 2025. The recent increase in ROE appears heavily influenced by the substantial improvement in Net Profit Margin.

The significant volatility in Net Profit Margin appears to be the primary driver of the observed changes in ROE. While Asset Turnover and Financial Leverage experienced some fluctuations, their impact on ROE was less pronounced. The recent strong performance in Net Profit Margin has resulted in a substantial increase in ROE, despite a slight decrease in Financial Leverage and a relatively stable Asset Turnover.

The five-component DuPont analysis reveals significant fluctuations in Return on Equity (ROE) over the observed period. These fluctuations are driven by changes in profitability, asset utilization, and financial leverage, as well as tax and interest burdens. A notable shift in performance is evident between the earlier and later periods examined.

Tax Burden

The tax burden generally remained relatively stable between March 2022 and December 2022, fluctuating between 0.73 and 0.79. A substantial decrease is observed starting in March 2024, falling to 0.44, before recovering to between 0.82 and 0.88 in subsequent quarters. This suggests a significant change in the company’s effective tax rate or tax planning strategies during that period.

Interest Burden

Similar to the tax burden, the interest burden exhibited stability between March 2022 and December 2022, ranging from 0.83 to 0.89. A marked decline is then seen beginning in March 2024, reaching a low of 0.16 in September 2024, before increasing again to 0.91 by December 2025. This indicates a change in the company’s debt structure or interest rate environment.

EBIT Margin

The EBIT margin demonstrated volatility. It ranged from 20.57% to 25.25% in 2022, increased to between 25.92% and 30.79% in 2023, then experienced a dramatic decline, falling to 7.58% in March 2024. The margin showed some recovery, reaching 37.42% by December 2025, indicating improved operational efficiency or pricing power in the latter part of the period. This is the most significant driver of ROE changes.

Asset Turnover

Asset turnover remained relatively consistent at approximately 0.43 to 0.44 between March 2022 and December 2022. A slight increase to between 0.51 and 0.52 is observed in the first half of 2024, followed by a return to the 0.49 to 0.51 range. This suggests a modest improvement in the efficiency of asset utilization, but the impact on ROE is limited compared to other factors.

Financial Leverage

Financial leverage decreased gradually from 3.17 in March 2022 to 2.60 in December 2025. This indicates a reduction in the company’s reliance on debt financing. While leverage generally amplifies ROE, the decreasing trend suggests a more conservative capital structure.

Return on Equity (ROE)

ROE mirrored the trends in the underlying components. It decreased from 22.66% in March 2022 to 15.82% in September 2022, then recovered to 26.59% in March 2023. A substantial decline occurred in early 2024, with ROE falling to 2.77% in March 2024. ROE then exhibited a strong recovery, reaching 37.48% by December 2025, primarily driven by the significant improvement in the EBIT margin. The interplay between profitability, leverage, and tax/interest burdens heavily influenced these fluctuations.

In summary, the analysis highlights a period of significant change. The substantial decline in ROE in early 2024, followed by a robust recovery, warrants further investigation. The primary driver of these changes appears to be the EBIT margin, with notable influences from the tax and interest burdens. The relatively stable asset turnover and decreasing financial leverage played secondary roles in the overall ROE performance.

The financial performance, as indicated by the two-component disaggregation of Return on Assets (ROA), exhibits notable fluctuations over the observed period. Initially, from March 31, 2022, through December 31, 2022, ROA remained relatively stable, fluctuating between 6.58% and 7.27%. A significant upward trend in profitability followed, culminating in a peak in September 2023, before experiencing a sharp decline and subsequent recovery. Asset utilization also demonstrated some variability, though to a lesser extent.

Net Profit Margin

The Net Profit Margin demonstrated a generally increasing trend from March 31, 2022 (16.60%) to September 30, 2025 (28.41%). A substantial decrease is observed in the first half of 2024, falling to 1.78% in March and 3.82% in June, before recovering to 0.45% and 1.68% by the end of the year. The margin then experiences a strong rebound, reaching 20.87% and 21.98% in the first two quarters of 2025, and continuing to 28.41% and 29.43% in the subsequent quarters. This suggests a period of reduced profitability followed by a strong recovery and sustained high margins.

Asset Turnover

Asset Turnover remained consistently around 0.43 for the majority of the period, from March 31, 2022, to December 31, 2022. A slight increase is noted in the first half of 2023, reaching 0.44, before returning to 0.43. A further increase is observed in the first half of 2024, peaking at 0.52 in June, followed by a decline to 0.48 by the end of the year. The ratio stabilizes around 0.49-0.51 in 2025, indicating a modest improvement in asset utilization compared to the earlier period.

Return on Assets (ROA)

ROA mirrored the trends in Net Profit Margin. It began at 7.16% in March 2022 and remained relatively stable through the end of 2022. A clear upward trend emerges in 2023, peaking at 9.42% in September. The significant drop in Net Profit Margin in the first half of 2024 directly impacted ROA, causing it to fall to 0.86% and 1.97%. The subsequent recovery in profitability led to a substantial increase in ROA, reaching 10.57% and 11.33% in the first two quarters of 2025, and continuing to 13.86% and 14.42% in the subsequent quarters. The strong correlation between ROA and Net Profit Margin highlights the dominant influence of profitability on overall asset performance.

The observed fluctuations suggest a sensitivity of overall returns to changes in profitability. While asset utilization remained relatively stable, the significant swings in Net Profit Margin were the primary driver of changes in ROA. The recent recovery in both metrics indicates a positive shift in financial performance, with the company demonstrating an increasing ability to generate profits from its assets.

The financial performance, as disaggregated through a four-component DuPont analysis, reveals notable shifts over the observed period. Return on Assets (ROA) experienced fluctuations, initially declining then increasing significantly, followed by a recent period of stabilization. This analysis details the drivers behind these changes, focusing on the interplay between Tax Burden, Interest Burden, EBIT Margin, and Asset Turnover.

EBIT Margin

The EBIT Margin demonstrated volatility. From March 2022 to September 2022, a decline was observed, followed by a recovery and peaking in March 2023. A substantial decrease occurred in March 2024, with subsequent moderate improvement through December 2025. This suggests potential shifts in operational efficiency or pricing strategies impacting profitability. The significant increase in EBIT Margin from September 2024 through December 2025 is a key driver of the ROA improvement during that period.

Tax Burden

The Tax Burden generally remained relatively stable between March 2022 and December 2022, fluctuating between 0.73 and 0.79. A significant drop occurred in March 2024 to 0.44, before increasing again to 0.87 by December 2025. This variability in the Tax Burden directly impacts net income and, consequently, ROA. The lower tax burden in early 2024 contributed to a temporary increase in ROA despite a concurrent decline in EBIT Margin.

Interest Burden

The Interest Burden exhibited a similar pattern to the Tax Burden, remaining relatively consistent between March 2022 and December 2022, around 0.85. A substantial decrease was noted in March 2024, falling to 0.53, followed by a further decline to 0.16 in September 2024. It then increased again, reaching 0.91 by December 2025. This suggests changes in the company’s capital structure or interest rate environment. The lower interest burden in the first half of 2024 positively influenced ROA.

Asset Turnover

Asset Turnover remained consistently around 0.43 to 0.44 for the majority of the period, until March 2024, when it began to increase, peaking at 0.52 in June 2024. It then decreased slightly to 0.49 by December 2025. This indicates a moderate improvement in the efficiency with which assets are used to generate sales, contributing to the overall ROA improvement in 2024 and 2025.

The initial decline in ROA from March 2022 to September 2022 appears driven by a combination of decreasing EBIT Margin and relatively stable Tax Burden and Interest Burden, with Asset Turnover remaining constant. The subsequent increase in ROA, particularly from March 2023 onwards, is attributable to improvements in EBIT Margin, coupled with favorable shifts in Tax and Interest Burdens, and a modest increase in Asset Turnover. The stabilization of ROA in the latter part of the period suggests a balancing of these factors. The significant changes observed in Tax and Interest Burdens warrant further investigation to understand the underlying causes and their sustainability.

The period under review demonstrates significant fluctuations in profitability metrics, particularly concerning the disaggregation of net profit margin through tax and interest burdens, and their relationship to EBIT margin. A notable shift in these ratios is observed between the earlier and later periods.

Tax Burden

The tax burden generally remained relatively stable between March 2022 and December 2022, fluctuating between 0.73 and 0.79. A substantial decrease is then evident, falling to 0.44 by March 2024, before recovering to levels between 0.82 and 0.88 by December 2025. This suggests a potential impact from changes in tax regulations or strategic tax planning initiatives, followed by a return to more typical levels.

Interest Burden

Similar to the tax burden, the interest burden exhibited relative stability between March 2022 and December 2022, ranging from 0.83 to 0.89. A marked reduction occurs starting in March 2024, reaching a low of 0.16 by September 2024. The interest burden then increases progressively, stabilizing between 0.91 and 0.92 by the end of the observed period. This pattern could indicate debt restructuring, refinancing activities, or changes in the overall interest rate environment.

EBIT Margin

The EBIT margin showed volatility throughout the period. It decreased from 25.25% in March 2022 to 20.57% in September 2022, then recovered to 25.11% by December 2022. A significant increase is observed from March 2023 to September 2025, peaking at 38.20% before slightly decreasing to 37.42%. This suggests strong operational performance and cost management improvements, particularly in the later part of the period.

Net Profit Margin

The net profit margin mirrored the trends in EBIT margin, though with a more pronounced effect from the tax and interest burdens. It declined from 16.60% in March 2022 to 12.44% in September 2022, then increased to 17.02% by December 2022. A dramatic decline is observed from March 2024, reaching a low of 0.45% in September 2024. Subsequently, the net profit margin experienced substantial growth, reaching 29.43% by December 2025. This indicates that changes in tax and interest expenses significantly impacted the bottom line, and that recent improvements in EBIT margin have been effectively translated into higher net profits.

The convergence of decreasing tax and interest burdens with increasing EBIT margin in the latter portion of the period resulted in a substantial improvement in net profit margin. The earlier period demonstrates a more consistent, but lower, level of profitability. The observed shifts suggest a dynamic financial landscape and potentially successful strategic financial management.
