The analysis of Return on Equity (ROE) reveals a significant transition in the drivers of profitability between December 2020 and March 2026. The initial period was characterized by exceptionally high ROE, peaking at 112.56% in June 2021, followed by a sustained decline and subsequent stabilization at lower levels.

Return on Assets (ROA) Trends

Asset efficiency exhibited a cyclical pattern throughout the observed period. ROA increased from 17.95% in late 2020 to a peak of 27.35% by June 2022. This was followed by a contraction phase, with the ratio falling to a low of 14.17% in September 2023. While a recovery trend emerged through June 2025, reaching 21.10%, a sharp decline to 10.12% was recorded in December 2025 before rebounding to 17.37% in March 2026.

Financial Leverage Dynamics

A consistent and pronounced deleveraging trend is evident. The leverage ratio decreased steadily from a high of 5.08 in December 2020 to a minimum of 2.00 by March 2025. This represents a substantial reduction in the use of debt to amplify equity returns, indicating a shift toward a more conservative capital structure.

ROE Disaggregation and Correlation

The overall decline in ROE from its 2021 peak was driven by the simultaneous reduction in financial leverage and fluctuations in ROA. During the early stages of the period, high leverage acted as a powerful multiplier for asset returns. As the leverage ratio decreased by approximately 60%, ROE became significantly more dependent on operational efficiency. The trough in ROE observed in December 2025 (23.25%) corresponds directly with the period of lowest asset performance, confirming that the diminished leverage multiplier has made equity returns more sensitive to changes in ROA.

The analysis of the three-component DuPont decomposition reveals a significant long-term contraction in Return on Equity (ROE), which peaked at 112.56% in June 2021 before trending downward to 36.38% by March 2026. This decline is not the result of a single factor but is driven by a sustained reduction in financial leverage, complemented by cyclical fluctuations in profitability and asset efficiency.

Financial Leverage

The most consistent and impactful trend is the aggressive deleveraging of the balance sheet. Financial leverage declined steadily from a high of 5.08 in December 2020 to a low of 2.00 in March 2025. This persistent reduction in the equity multiplier acted as the primary catalyst for the decline in ROE, indicating a strategic shift toward a more conservative capital structure and reduced reliance on debt to amplify returns.

Net Profit Margin

Profitability exhibited a cyclical pattern with a notable period of volatility. Margins initially expanded from 25.21% in December 2020 to a peak of 30.52% in June 2022. A subsequent contraction occurred through September 2023, where margins dipped to 20.19%, followed by a recovery toward 26.76% by June 2025. A sharp, temporary collapse in profitability is observed in the second half of 2025, with margins falling to 11.96% in December 2025, before recovering to 22.31% in March 2026.

Asset Turnover

Asset efficiency showed moderate volatility, generally fluctuating between 0.68 and 0.90. An initial improvement in asset utilization was observed from December 2020 (0.71) to September 2022 (0.90). This was followed by a period of relative inefficiency, bottoming out at 0.68 in March 2024. A recovery phase ensued, peaking at 0.88 in June 2025, suggesting an improved ability to generate revenue from the asset base during that period.

In summary, the substantial erosion of ROE over the analyzed period is predominantly attributable to the reduction in financial leverage. While profit margins and asset turnover experienced temporary declines—most notably the sharp margin compression in late 2025—these operational fluctuations were secondary to the structural change in the company's leverage profile. The recovery of ROE to 36.38% in the final period was driven by a rebound in net profit margins despite continued low leverage.

The Return on Equity (ROE) exhibited significant volatility and a general downward trajectory over the analyzed period. Starting from a peak of 112.56% in June 2021, ROE declined steadily to a low of 33.51% by September 2023. While a moderate recovery occurred through mid-2025, reaching 42.55%, a sharp contraction was observed in late 2025 before a rebound to 36.38% by March 2026.

Financial Leverage

The most substantial driver of the long-term decline in ROE was a consistent reduction in financial leverage. The leverage ratio fell from a high of 5.08 in December 2020 to a low of 2.00 by March 2025. This systemic deleveraging indicates a significant shift in the capital structure, reducing the magnification effect of equity and contributing heavily to the compression of the overall return on equity.

Operational Efficiency (EBIT Margin and Asset Turnover)

Operational performance showed cyclical fluctuations. The EBIT margin peaked at 36.30% in June 2022 before contracting to 22.42% in September 2023. A recovery phase followed, with margins returning to approximately 27.83% to 30.09% by 2025 and 2026. Similarly, asset turnover improved from 0.71 in late 2020 to a peak of 0.90 in mid-2022, followed by a dip to 0.68 in March 2024 and a subsequent recovery to 0.88 by September 2025. These movements suggest periods of operational pressure followed by successful efficiency gains.

Tax and Interest Burdens

The interest burden remained remarkably stable, fluctuating narrowly between 0.91 and 0.97, suggesting a consistent cost of debt relative to operating profit. The tax burden remained steady between 0.87 and 0.99 for most of the period; however, a severe anomaly occurred in September and December 2025, where the ratio dropped to 0.44 and 0.43, respectively. This sharp decline aligns with the temporary collapse in ROE during the same window, indicating a substantial one-time tax impact or adjustment before normalizing to 0.85 in March 2026.

The Return on Assets (ROA) exhibited significant volatility between December 2020 and March 2026, characterized by an initial expansion phase, a period of contraction, and a sharp fluctuation in late 2025.

Net Profit Margin

Profitability demonstrated an upward trajectory from December 2020, reaching a peak of 30.52% in June 2022. This was followed by a period of compression, with margins declining to 20.19% by September 2023. A recovery phase ensued, bringing margins back to 26.76% by June 2025. However, a severe contraction is observed in the second half of 2025, where margins dropped to a period low of 11.96% in December 2025, before rebounding to 22.31% in March 2026.

Asset Turnover

Asset utilization improved steadily from 0.71 in December 2020 to a peak of 0.90 in June 2022. A gradual decline in efficiency followed, reaching a minimum of 0.68 in March 2024. An anomalous spike in turnover is noted in September 2025, reaching 0.88, which indicates an increase in revenue generation relative to the asset base during a period of significant margin decline.

ROA Disaggregation and Integration

The fluctuations in ROA are primarily driven by the net profit margin, although asset turnover provided moderate support during the initial growth phase. The peak ROA of 27.35% in June 2022 resulted from the simultaneous optimization of both profit margins and asset turnover. The most significant decline in ROA occurred in December 2025, reaching 10.12%; this was caused by a sharp drop in profitability that exceeded the offsetting effect of increased asset turnover. The recovery of ROA to 17.37% by March 2026 is directly attributable to the restoration of the net profit margin.

The Return on Assets (ROA) exhibited significant volatility over the analyzed period, characterized by a strong growth phase through mid-2022, a subsequent contraction throughout 2023, and a sharp, temporary decline in the latter half of 2025.

EBIT Margin

Operating profitability demonstrated a cyclical trend. Margins expanded from 29.87% in December 2020 to a peak of 36.30% in June 2022. A subsequent downward trajectory was observed, reaching a trough of 22.42% in September 2023. A recovery phase followed, with margins stabilizing around the 29-30% range through mid-2025, before settling at 27.83% by March 2026.

Asset Turnover

Asset utilization efficiency peaked in mid-2022 at 0.90, correlating with the period of maximum ROA. A contraction in turnover efficiency occurred between late 2022 and early 2024, reaching a minimum of 0.68 in March 2024. Efficiency improved thereafter, returning to 0.88 by June 2025, indicating an enhanced ability to generate revenue from the asset base.

Interest Burden

The interest burden remained consistently stable, fluctuating within a narrow band between 0.91 and 0.97. This stability indicates that the cost of debt serviced by the company had a negligible and consistent impact on the conversion of operating profit to pre-tax income across the entire timeline.

Tax Burden

The tax burden was generally stable, typically ranging between 0.87 and 0.99. A significant anomaly is observed in the second half of 2025, where the ratio plummeted to 0.44 in September and 0.43 in December. This precipitous decline served as the primary driver for the sharp contraction in ROA during those specific quarters, despite the relative stability of operating margins and asset turnover.

Analysis indicates that ROA was predominantly driven by operating efficiency and asset utilization through early 2025. The significant dip in returns observed in late 2025 was not an operational failure, but rather a result of a sharp decrease in the tax burden ratio, suggesting a substantial one-time tax impact or adjustment.

The net profit margin exhibits a cyclical pattern characterized by a period of expansion, a subsequent contraction, and a significant volatility event in late 2025. The margin peaked at 30.52% in June 2022 before experiencing a downward trend that reached a trough of 20.19% in September 2023. While margins recovered to the 26% range by mid-2025, a sharp decline occurred in the second half of 2025, with margins falling to 11.96% in December 2025, followed by a strong recovery to 22.31% by March 2026.

EBIT Margin Trends

Operating profitability showed strong growth from December 2020 (29.87%) to a peak of 36.30% in June 2022. A period of margin compression followed, with the EBIT margin falling to a low of 22.42% in September 2023. This was followed by a gradual recovery phase, stabilizing around 29% to 30% between December 2024 and June 2025, before settling at 27.83% by March 2026.

Tax Burden Analysis

The tax burden remained relatively stable, fluctuating between 0.87 and 0.99 for the majority of the period. However, a severe anomaly is observed in September and December 2025, where the ratio plummeted to 0.44 and 0.43, respectively. This indicates a substantial increase in the effective tax rate during these two quarters, which served as the primary driver for the simultaneous collapse in the net profit margin, despite stable operating margins.

Interest Burden Stability

The interest burden remained the most consistent component of the margin disaggregation. The ratio fluctuated within a narrow band between 0.91 and 0.97 throughout the entire analyzed period. This stability suggests that interest expenses had a negligible and predictable impact on the conversion of operating income to net income.

Analysis indicates that while the long-term fluctuations in net profit margin were initially driven by shifts in operating efficiency (EBIT margin), the extreme volatility observed in late 2025 was exclusively attributed to the tax burden. The divergence between a stable EBIT margin of approximately 30% and a net profit margin of approximately 12% during that period confirms that the profitability dip was non-operational in nature.
