The two-component DuPont analysis reveals that fluctuations in Return on Equity (ROE) are predominantly driven by changes in Return on Assets (ROA), as Financial Leverage remained relatively stable throughout the period from March 2022 to September 2026.

Return on Equity (ROE) Performance

ROE exhibited significant volatility over the analyzed timeframe. A period of relative stability and strength was observed between March 2022 and December 2023, with values peaking at 26.03% in September 2022. A sharp contraction occurred in 2024, with ROE dropping to a low of 15.14% by September 2024. Although a brief recovery to 23.26% was noted in March 2025, a subsequent downward trend led to a period low of 12.30% in March 2026, before beginning a moderate recovery to 16.19% by September 2026.

Return on Assets (ROA) Trends

The movement of ROA closely mirrors the trajectory of ROE. High asset productivity was maintained through 2022 and 2023, reaching a peak of 8.19% in December 2022. A marked decline began in March 2024 (5.40%), continuing toward a trough in March 2026 at 3.85%. This indicates that the overall decline in equity returns was fundamentally caused by a reduction in the net income generated per unit of asset, rather than a change in financial structure.

Financial Leverage Stability

Financial leverage remained consistent, fluctuating within a narrow range between 3.04 and 3.49. The peak leverage of 3.49 was recorded in March 2023, while the lowest point of 3.04 occurred in March 2022. Because this multiplier stayed relatively constant, it did not serve as a primary driver for the volatility seen in the final ROE figures.

Component Correlation and Synthesis

The analysis demonstrates a direct positive correlation between ROA and ROE. The stability of the financial leverage ratio suggests that the organization did not rely on increased borrowing to bolster equity returns during periods of declining asset performance. Consequently, the deterioration of ROE observed in 2024 and early 2026 is attributable exclusively to the compression of ROA, reflecting a decline in operational efficiency or profitability relative to the asset base.

The analysis of the three-component DuPont decomposition reveals that the volatility in Return on Equity (ROE) is primarily driven by fluctuations in the Net Profit Margin, while Asset Turnover and Financial Leverage remained relatively stable over the observed period.

Net Profit Margin

A period of relative stability is observed from March 2022 through December 2023, with margins ranging between 5.91% and 6.25%. However, a significant contraction occurred starting in March 2024, where the margin dropped to 4.09%. This downward pressure continued through 2025, reaching a low of 2.72% in December 2025. A modest recovery is evident in the first three quarters of 2026, with the margin rising to 3.56% by September 2026.

Asset Turnover

Asset utilization remained consistently stable, fluctuating within a narrow band between 1.18 and 1.44. A gradual upward trend is observable from March 2023 (1.18) through June 2026 (1.44), suggesting a steady improvement in the efficiency of generating revenue from the asset base. This incremental improvement acted as a slight counterbalance to the declining profit margins.

Financial Leverage

The capital structure remained consistent throughout the analysis period. The leverage ratio fluctuated minimally between a low of 3.04 in March 2022 and a peak of 3.49 in March 2023. The absence of significant spikes or drops in this ratio indicates that changes in ROE were not the result of aggressive changes in debt levels or equity restructuring.

Return on Equity (ROE)

ROE exhibited a strong correlation with the Net Profit Margin. After maintaining a high plateau between 23.98% and 26.07% from early 2022 to late 2023, ROE experienced a sharp decline in 2024, hitting a low of 15.14% in September 2024. Although a temporary spike to 23.26% occurred in March 2025, the metric trended downward to a period low of 12.30% in March 2026. A recovery phase began thereafter, ending the period at 16.19% in September 2026.

In summary, the overall decline and subsequent volatility in ROE were almost exclusively attributable to the compression of net profit margins. The stability of financial leverage and the slight improvement in asset turnover demonstrate that the underlying operational efficiency and financial risk profile remained constant, while profitability faced significant headwinds during the 2024-2026 window.

The Return on Equity (ROE) exhibits significant volatility over the analyzed period, characterized by a period of stability followed by two distinct downturns. From March 2022 through December 2023, ROE remained consistently high, peaking at 26.03% in September 2022. A sharp contraction occurred in early 2024, where ROE fell to 15.14% by September 2024. Although a brief recovery to 23.26% was recorded in March 2025, a secondary and more severe decline followed, with ROE reaching a period low of 12.30% in March 2026 before recovering to 16.19% by September 2026.

Operating Profitability

The EBIT Margin serves as the primary driver of ROE volatility. The margin was stable and strong between 8.04% and 8.70% from March 2022 to December 2023. However, a significant compression began in March 2024, with the margin dropping to 5.86% by December 2024. Despite a temporary spike to 7.76% in March 2025, the margin entered a sustained decline, bottoming out at 3.98% in March 2026. This erosion in operating profitability correlates directly with the observed declines in overall equity returns.

Asset Utilization

Asset Turnover remained relatively stable throughout the period, fluctuating within a narrow range between 1.18 and 1.44. There is a observable gradual upward trend in efficiency toward the end of the sequence, with the ratio increasing from 1.32 in December 2024 to a peak of 1.44 in June 2026. This suggests that while operational efficiency improved, it was insufficient to offset the decline in profit margins.

Financial Leverage

Financial Leverage showed moderate fluctuations but lacked a definitive long-term directional trend. The ratio peaked at 3.49 in March 2023 and reached a low of 3.04 in March 2022. For the majority of 2024 and 2025, leverage remained consistent, hovering between 3.15 and 3.29. The stability of this component indicates that the volatility in ROE was not caused by changes in the capital structure or aggressive borrowing.

Tax and Interest Burdens

The Tax Burden remained stable near 0.79 for the first two years before dipping to 0.73 in early 2024 and subsequently rising to a peak of 0.87 by March 2026. The Interest Burden showed a more pronounced downward trend, declining from 0.93 in 2022 to a low of 0.78 in December 2025, before recovering to 0.83 in September 2026. The decline in the interest burden ratio indicates an increase in interest expenses relative to EBIT, which contributed to the downward pressure on net income and ROE during the 2025-2026 period.

The analysis of Return on Assets (ROA) reveals a period of initial stability and growth followed by significant volatility and a general downward shift in profitability efficiency starting in early 2024. While asset utilization remained consistent or improved over the observed period, the overall return was primarily driven by fluctuations in net profit margins.

Net Profit Margin

A period of stability was observed from March 2022 through December 2023, with margins oscillating between 5.91% and 6.25%. However, a sharp contraction occurred in March 2024, where the margin fell to 4.09%, reaching a low of 3.65% by December 2024. Despite a brief recovery in early 2025, peaking at 5.46%, a subsequent decline led to a period low of 2.70% in March 2026, before a modest recovery to 3.56% by September 2026.

Asset Turnover

Asset utilization remained relatively stable throughout the analysis period. Following a brief dip to 1.18 in March 2023, a consistent upward trend is observable. The ratio climbed from 1.32 in December 2023 to a peak of 1.44 in June 2026. This indicates a steady improvement in the efficiency of generating revenue from the asset base, independent of profitability fluctuations.

Return on Assets (ROA)

The ROA mirrored the movements of the net profit margin due to the relative stability of the asset turnover ratio. Strong performance was noted through 2022 and 2023, with values consistently above 7.30% and peaking at 8.19% in December 2022. A significant decline occurred in 2024, with ROA dropping to a low of 4.78% in September 2024. A temporary rebound to 7.14% in March 2025 was followed by a steep decline to 3.85% by March 2026, ending with a recovery to 5.08% by September 2026.

The disaggregation of ROA demonstrates that the deterioration in overall asset returns was not a result of operational inefficiency in asset usage, but rather a compression of net profit margins. The increasing trend in asset turnover served as a partial buffer, preventing a more severe decline in ROA during the periods of margin contraction.

The Return on Assets (ROA) exhibits a period of relative stability followed by significant volatility between 2024 and 2026. After maintaining levels between 7.89% and 8.19% throughout 2022 and most of 2023, ROA experienced a sharp contraction beginning in early 2024. Despite a brief recovery in the first quarter of 2025, the metric reached its lowest point of 3.85% in March 2026, before initiating a gradual recovery to 5.08% by September 2026.

EBIT Margin

The EBIT margin serves as the primary driver of ROA volatility. A consistent performance range of 8.04% to 8.70% was observed from March 2022 through December 2023. However, a marked decline began in March 2024, with margins falling to 5.86% by the end of that year. A temporary spike to 7.76% occurred in March 2025, followed by a severe contraction to a low of 3.98% in March 2026. The margin began a modest recovery trend in the latter half of 2026, reaching 5.12%.

Asset Turnover

Asset turnover remained the most stable component of the ROA disaggregation, generally fluctuating between 1.18 and 1.44. A gradual improvement in asset utilization is evident from 2024 onwards, with the ratio increasing from 1.32 in March 2024 to a peak of 1.44 in June 2026. This indicates that operational efficiency in utilizing assets improved even as profitability margins faced downward pressure.

Interest Burden

The interest burden showed a gradual downward trend from 0.93 in 2022 to 0.83 by December 2024, suggesting an increase in the proportion of operating profit consumed by interest expenses. This pressure intensified in late 2025, reaching a minimum of 0.78 in December 2025, which coincided with the period of lowest ROA. The ratio recovered to 0.83 by September 2026.

Tax Burden

The tax burden remained stable at approximately 0.78 to 0.79 through 2023. A dip to 0.73 was recorded in the first half of 2024, indicating a higher effective tax impact during that period. Subsequently, the ratio trended upward, peaking at 0.87 in March 2026, which implies a reduction in the tax burden relative to pre-tax income toward the end of the analyzed period.

Overall, the analysis indicates that the decline in ROA was not a result of asset inefficiency, as asset turnover improved over time. Instead, the erosion of return was driven by a significant compression of the EBIT margin and exacerbated by a periodic increase in the interest burden during 2025. The recovery observed in 2026 is primarily attributed to a rebound in operating margins and a more favorable tax burden ratio.

The overall profitability trajectory between March 2022 and September 2026 is characterized by an initial period of stability followed by significant volatility and a general decline in margin performance. The net profit margin, which remained relatively steady above 6% through 2023, experienced a sharp contraction starting in early 2024, reaching its lowest point in early 2026 before showing signs of a modest recovery.

EBIT Margin

Operational efficiency showed a gradual improvement through 2022 and 2023, peaking at 8.70% in March 2023. However, a substantial downward shift occurred in 2024, with the margin falling to 5.86% by year-end. The 2025 period was marked by extreme volatility, featuring a brief recovery to 7.76% in the first quarter followed by a precipitous decline to 4.05% by December 2025. A recovery trend emerged in 2026, with the margin climbing back to 5.12% by September.

Interest Burden

The interest burden remained stable between 0.90 and 0.93 during the first two years of the period. A decline began in 2024, reaching a low of 0.83 by December, which indicates an increase in the proportion of operating profit consumed by interest expenses. While there was a temporary improvement in early 2025, the ratio declined again to 0.78 by the end of 2025, before recovering slightly to 0.83 in the latter half of 2026.

Tax Burden

The tax burden ratio exhibited a fluctuating pattern, remaining constant at approximately 0.78 to 0.79 throughout 2022 and 2023. A temporary decrease to 0.73 was observed in early 2024. From March 2025 onward, the ratio trended upward, peaking at 0.87 in March 2026. This upward movement suggests a reduction in the effective tax rate relative to pre-tax income during the latter stage of the analyzed period.

Net Profit Margin

The net profit margin reflects the cumulative impact of the three components mentioned above. After maintaining levels between 5.91% and 6.25% from March 2022 through December 2023, the margin dropped sharply to 4.09% in March 2024. Despite a transient spike to 5.46% in March 2025, the margin eroded to a period low of 2.70% by March 2026. The final quarters of the analysis show a gradual recovery, ending at 3.56% in September 2026.
