The two-component DuPont analysis reveals that fluctuations in Return on Equity (ROE) are driven almost exclusively by changes in Return on Assets (ROA), as financial leverage has remained remarkably stable following a structural adjustment in late 2021.

Return on Assets (ROA)

ROA exhibits significant volatility over the analyzed period. An initial peak of 7.86% in July 2021 was followed by a sharp contraction, reaching a low of 2.50% by January 2022. A subsequent recovery trend occurred throughout 2022 and early 2023, peaking at 7.60% in July 2023. This was followed by another period of decline, bottoming at 3.26% in February 2024, before entering a consistent upward trajectory that reached 6.91% by May 2026.

Financial Leverage

A distinct shift in capital structure is observed between July 2021 and October 2021, where the leverage ratio decreased from 1.76 to 1.38. Following this adjustment, the leverage ratio remained highly stabilized, fluctuating within a narrow range between 1.35 and 1.42. This indicates a consistent approach to debt and equity management, minimizing the impact of financial gearing on the overall return to shareholders.

Return on Equity (ROE)

ROE patterns mirror the movement of ROA with high correlation. The highest return of 13.87% was recorded in July 2021, coinciding with both peak asset efficiency and higher leverage. The subsequent decline to 3.43% in January 2022 reflects the dual impact of falling ROA and reduced leverage. Recent performance indicates a recovery phase, with ROE climbing from 4.46% in November 2024 to 9.82% by May 2026, driven by the steady improvement in operational asset returns while leverage remained constant.

The return on equity (ROE) exhibits significant volatility over the analyzed period, characterized by two distinct cycles of contraction and recovery. The ROE peaked early at 13.87% in July 2021 before experiencing a sharp decline to 3.43% by January 2022. A subsequent recovery led to a secondary peak of 10.45% in April 2023, followed by another downturn reaching 4.46% in February 2025, and ending on an upward trajectory at 9.82% in May 2026.

Net Profit Margin

Profitability demonstrates a cyclical pattern that closely correlates with ROE movements. The margin initially ranged between 23.99% and 26.15% in 2021, before dropping to a period low of 15.18% in January 2022. A strong recovery phase occurred throughout 2023, reaching a maximum of 29.23% in July 2023. A second decline followed, with margins receding to 17.07% by August 2024, before steadily improving to 26.01% by May 2026.

Asset Turnover

Operational efficiency mirrored the volatility seen in profit margins. Asset turnover started at a high of 0.30 in July 2021 but fell sharply to 0.14 by October 2021. Efficiency improved gradually through 2022 and 2023, stabilizing around 0.26. A subsequent dip saw the ratio fall to 0.19 in February 2025, followed by a recovery to 0.27 by May 2026, suggesting a return to previous levels of asset utilization.

Financial Leverage

The capital structure remained the most stable component of the ROE disaggregation. Financial leverage began at 1.77 but shifted downward to a range of 1.36 to 1.39 starting in late 2021. This leverage ratio remained largely stagnant for several years, with only a slight increase to 1.42 observed between May 2025 and May 2026. Consequently, leverage did not act as a primary driver for the fluctuations in ROE.

Integrated ROE Drivers

The fluctuations in ROE are primarily attributed to the simultaneous movement of net profit margins and asset turnover. The deepest troughs in ROE occurred when both profitability and asset efficiency declined concurrently, as seen in early 2022 and early 2025. Because financial leverage remained relatively constant, the overall return on equity was almost entirely dependent on the company's ability to maintain pricing power and optimize asset usage.

The Return on Equity (ROE) exhibits significant volatility over the analyzed period, characterized by a sharp contraction in early 2022 followed by cyclical fluctuations. After peaking at 13.87% in July 2021, ROE dropped precipitously to 3.43% by January 2022. While a recovery occurred through July 2023, reaching 10.45%, another downturn was observed in 2024 before a steady upward trajectory resumed, ending at 9.82% by May 2026.

Operating Profitability (EBIT Margin)

The EBIT margin serves as the primary driver of ROE volatility. High margins exceeding 30% in early 2021 collapsed to 16.70% by January 2022. A strong recovery phase followed, with margins peaking at 33.69% in July 2023, before experiencing another compression to 21.63% in January 2025. The period concludes with a robust recovery to 33.46% in May 2026, suggesting a return to peak operational efficiency.

Asset Efficiency (Asset Turnover)

Asset turnover demonstrates a pattern closely aligned with operational profitability. A significant drop to 0.14 was recorded in October 2021, indicating a period of decreased asset productivity. Turnover improved to a range of 0.24 to 0.26 during 2023 but weakened again in 2024. An improvement trend is evident toward the end of the series, with the ratio reaching 0.27 by May 2026.

Financial Leverage

A structural shift in the capital base is evident as financial leverage decreased from 1.77 in early 2021 to a more stable range between 1.35 and 1.42 for the remainder of the period. This reduction in leverage suggests a more conservative financing strategy or an increase in equity relative to assets, which limited the potential for leverage-driven ROE amplification.

Tax and Interest Burdens

The interest burden remained relatively stable, fluctuating between 0.84 and 0.95, indicating consistent management of interest expenses relative to operating profit. The tax burden remained steady around 0.92 for most of the period but experienced a notable decline to 0.84 starting in August 2025, which placed additional downward pressure on the final net income component of ROE during the final quarters.

The Return on Assets (ROA) exhibits significant volatility over the analyzed period, characterized by two distinct cycles of contraction and recovery. The metric reached an initial peak of 7.86% in July 2021 before experiencing a sharp decline, followed by a recovery peak of 7.60% in April 2023, and a subsequent trough of 3.26% in February 2025. The trajectory of ROA is driven by the simultaneous fluctuations of net profit margins and asset turnover efficiency.

Net Profit Margin Trends

Profitability demonstrates a cyclical pattern with substantial variance. An initial period of strength peaked at 26.15% in July 2021, followed by a contraction to a low of 15.18% in January 2022. A subsequent expansion phase saw margins climb to a period high of 29.23% by July 2023. A second contraction occurred between October 2023 and August 2024, where margins dipped to 17.07%, before entering a recovery phase that culminated in 26.01% by May 2026.

Asset Turnover Efficiency

Asset utilization reflects a high degree of sensitivity, mirroring the volatility seen in profitability. A significant drop in efficiency is observed in October 2021, where the ratio fell to 0.14. This was followed by a steady improvement, peaking at 0.26 between April and July 2023. A second decline occurred, reaching a low of 0.19 in February 2025, followed by a consistent upward trend returning to 0.27 by May 2026.

ROA Disaggregation and Correlation

The disaggregation of ROA reveals that the metric is most severely impacted when both net profit margin and asset turnover decline concurrently. The lowest ROA levels, such as the 2.50% recorded in January 2022, correspond with synchronized lows in both efficiency and profitability. Conversely, the recovery of ROA toward the end of the period is attributed to a dual improvement: the restoration of asset turnover to 0.27 and the expansion of net profit margins to 26.01%, suggesting a return to optimal operational leverage and pricing power.

Return on Assets (ROA) exhibits significant volatility over the analyzed period, characterized by a cyclical pattern of contraction and recovery. The metric peaked early in 2021 at 7.86% before experiencing a sharp decline to a trough of 2.50% by January 2022. A subsequent recovery period saw ROA climb back to 7.60% by July 2023, followed by another downturn in 2024, and a final upward trajectory reaching 6.91% by May 2026.

Tax Burden

The tax burden remained relatively stable for the majority of the period, generally fluctuating between 0.89 and 1.05. A notable period of stability is observed between February 2024 and October 2024 at 0.92, followed by a decline to 0.84 from August 2025 through May 2026, indicating an increase in the effective tax impact on net income during the final stages of the period.

Interest Burden

The interest burden shows minimal variance, consistently operating within a narrow range of 0.84 to 0.95. A slight downward trend occurred between January 2023 and August 2024, where the ratio moved from 0.95 to 0.85, suggesting a marginal increase in interest expense relative to operating profit. However, a recovery trend is evident toward the end of the period, returning to 0.92 by May 2026.

EBIT Margin

The EBIT margin serves as a primary driver of ROA volatility. Operational profitability experienced a severe contraction from a high of 31.99% in July 2021 to a low of 16.70% in January 2022. A strong recovery followed, peaking at 33.69% in July 2023. Another cyclical dip occurred through 2024, with the margin bottoming at 21.63% in February 2025 before trending upward to 33.46% by May 2026.

Asset Turnover

Asset utilization efficiency followed a trajectory similar to the EBIT margin. Turnover ratios were strongest in early 2021, reaching 0.30, but collapsed to 0.14 by October 2021. While efficiency gradually improved through 2023, it faced another period of stagnation and slight decline in 2024, hovering around 0.20. A steady improvement is observed in the final year, with the ratio returning to 0.27 by May 2026.

The overall fluctuation in ROA is primarily attributable to the synchronized movements of the EBIT margin and asset turnover. The periods of lowest ROA coincide precisely with troughs in both operational profitability and asset efficiency. The recovery of ROA in the latter part of the timeline is driven by a simultaneous expansion of the EBIT margin and an increase in asset turnover, while the tax and interest burdens exerted only marginal influence on the total variance.

The disaggregation of the net profit margin reveals a cyclical trend in profitability, characterized by significant volatility in operating efficiency that serves as the primary driver for bottom-line fluctuations.

EBIT Margin Volatility

Operating performance exhibits substantial swings over the analyzed period. A peak of 33.69% was reached in July 2023, following a period of contraction where the margin dipped as low as 16.70% in January 2022. A subsequent decline occurred throughout 2024, hitting a trough of 22.10% in August 2024, before entering a steady recovery phase that culminated in 33.46% by May 2026. This indicates that fluctuations in the net profit margin are almost entirely dictated by operational profitability rather than financing or tax structures.

Tax Burden Analysis

The tax burden remained relatively stable for the majority of the period, generally fluctuating between 0.89 and 1.05. However, a notable shift is observed starting in August 2025, where the ratio declined and stabilized at 0.84. This decrease suggests an increase in the effective tax rate or a reduction in tax benefits during the final quarters of the sequence, which placed additional downward pressure on the net profit margin despite improving operating results.

Interest Burden Influence

The interest burden shows a consistent range between 0.84 and 0.95, indicating a stable relationship between EBIT and EBT. There was a gradual decline from 0.95 in early 2023 to 0.84 by February 2025, suggesting a slight increase in the relative weight of interest expenses. This was followed by a recovery toward 0.92 by May 2026, implying a reduction in interest pressure relative to operating income.

Net Profit Margin Synthesis

The net profit margin mirrors the trajectory of the EBIT margin with high precision. The peak net profit margin of 29.23% in July 2023 directly correlates with the peak in operational efficiency. Conversely, the contraction to 16.75% in February 2024 aligns with the downturn in EBIT margins. The final recovery to 26.01% by May 2026 demonstrates the strength of the operating recovery overcoming the headwinds of a lower tax burden ratio.
