Decomposing ROE involves expressing net income divided by shareholders’ equity as the product of component ratios.
Two-Component Disaggregation of ROE
Based on: 10-K (reporting date: 2022-12-31), 10-K (reporting date: 2021-12-31), 10-K (reporting date: 2020-12-31), 10-K (reporting date: 2019-12-31), 10-K (reporting date: 2018-12-31).
The analysis of the two-component DuPont disaggregation reveals a significant transition in the drivers of Return on Equity (ROE) between 2018 and 2022. While ROE experienced a notable contraction during the 2020 period, the subsequent recovery indicates a fundamental shift from a leverage-dependent return model to one driven by improved operational asset efficiency.
- Return on Assets (ROA)
- Asset efficiency remained relatively stable between 2018 and 2019 before experiencing a decline to 4.98% in 2020. Following this trough, a strong upward trajectory was established, with ROA increasing to 6.83% in 2021 and reaching a peak of 8.70% by the end of 2022. This suggests a marked improvement in the company's ability to generate earnings from its asset base in the latter part of the period.
- Financial Leverage
- A consistent downward trend in financial leverage is observed from 2018 through 2021. The ratio declined from a high of 5.33 in 2018 to 3.39 in 2021, before stabilizing at 3.42 in 2022. This systemic reduction in the leverage ratio indicates a strategic deleveraging process or an increase in the equity base relative to total assets.
- Return on Equity (ROE) Dynamics
- The ROE fluctuated from 32.21% in 2018 to a low of 19.58% in 2020, eventually recovering to 29.81% by 2022. The 2020 decline was the result of a simultaneous drop in both ROA and financial leverage. However, the recovery of ROE in 2021 and 2022 was achieved despite the continued low leverage environment. This demonstrates that the growth in ROE in the final two years was driven exclusively by the expansion of ROA, resulting in a more sustainable and less risky return profile compared to the high-leverage structure seen in 2018.

Three-Component Disaggregation of ROE
Based on: 10-K (reporting date: 2022-12-31), 10-K (reporting date: 2021-12-31), 10-K (reporting date: 2020-12-31), 10-K (reporting date: 2019-12-31), 10-K (reporting date: 2018-12-31).
The Return on Equity (ROE) exhibited significant volatility between 2018 and 2022, declining from 32.21% to a low of 19.58% in 2020 before recovering to 29.81% by the end of 2022. This trajectory reflects a fundamental shift in the underlying drivers of shareholder returns, moving from a reliance on financial leverage toward a reliance on operational profitability.
- Net Profit Margin
- Operational profitability experienced a downturn between 2018 and 2020, reaching a period low of 10.43%. However, a robust recovery followed, with the margin expanding to 18.08% by 2022. This represents a significant increase in the company's ability to convert revenue into profit, becoming the primary catalyst for the recovery of ROE in the latter years of the analysis.
- Asset Turnover
- Asset utilization remained remarkably stable throughout the period. After a slight increase from 0.44 in 2018 to 0.49 in 2019, the ratio remained constant at 0.48 from 2020 through 2022. This indicates that the efficiency of generating sales from the asset base was neither a primary driver of the ROE decline nor a contributor to its subsequent recovery.
- Financial Leverage
- A consistent deleveraging trend is observed, with the financial leverage ratio decreasing from 5.33 in 2018 to 3.42 in 2022. The most pronounced reduction occurred between 2019 and 2021. This downward trend indicates a strategic shift toward a more conservative capital structure, reducing the amplification effect that debt previously provided to the ROE.
The synthesis of these three components indicates an improvement in the quality of the company's returns. The high ROE observed in 2018 was heavily supported by high financial leverage. In contrast, the ROE in 2022 was achieved despite a much lower leverage ratio, driven instead by a substantial expansion in net profit margins. This suggests that the current return profile is more sustainable and less dependent on financial risk.

Five-Component Disaggregation of ROE
Based on: 10-K (reporting date: 2022-12-31), 10-K (reporting date: 2021-12-31), 10-K (reporting date: 2020-12-31), 10-K (reporting date: 2019-12-31), 10-K (reporting date: 2018-12-31).
The Return on Equity (ROE) exhibited a V-shaped trajectory over the five-year period, starting at 32.21% in 2018, declining to a trough of 19.58% in 2020, and recovering to 29.81% by 2022. This volatility is the result of competing drivers across operating efficiency, financial leverage, and interest obligations.
- Operating Performance
- The EBIT Margin showed resilience, despite a contraction from 24.32% in 2018 to 21.20% in 2020. Following this period, a strong expansion occurred, culminating in a peak of 27.89% in 2022, suggesting improved operational efficiency and pricing power. Asset Turnover remained remarkably stable, holding at 0.48 for four consecutive years following an initial increase from 0.44 in 2018, indicating a consistent relationship between asset utilization and revenue generation.
- Financial Leverage and Interest Burden
- A significant and consistent deleveraging trend is evident, with the Financial Leverage ratio falling from 5.33 in 2018 to 3.42 in 2022. This reduction in financial risk likely exerted downward pressure on ROE. Simultaneously, the Interest Burden improved from a low of 0.63 in 2020 to 0.86 in 2022, reflecting a reduced impact of interest expenses on pre-tax income.
- Tax Burden
- The Tax Burden remained relatively stable throughout the analysis period, fluctuating within a narrow range between 0.74 and 0.78. This consistency indicates that changes in ROE were not driven by shifts in effective tax rates but rather by operational and capital structure adjustments.
Overall, the recovery of ROE toward 2022 was primarily propelled by substantial gains in EBIT Margin and a stronger Interest Burden, which effectively offset the systemic reduction in financial leverage.

Two-Component Disaggregation of ROA
Based on: 10-K (reporting date: 2022-12-31), 10-K (reporting date: 2021-12-31), 10-K (reporting date: 2020-12-31), 10-K (reporting date: 2019-12-31), 10-K (reporting date: 2018-12-31).
An analysis of the return on assets (ROA) from 2018 to 2022 reveals a fluctuating but ultimately upward trajectory. The ROA reached a period low of 4.98% in 2020 before expanding significantly to 8.70% by the end of 2022. This performance suggests a recovery and subsequent growth phase in asset productivity and profitability over the five-year period.
- Net Profit Margin
- The net profit margin exhibited significant volatility, characterized by a decline from 13.62% in 2018 to a trough of 10.43% in 2020. Following this decline, a strong recovery occurred, with the margin climbing to 14.27% in 2021 and peaking at 18.08% in 2022. This indicates a substantial improvement in cost management or pricing power in the latter two years of the period.
- Asset Turnover
- Asset turnover remained remarkably stable throughout the analyzed period. After an initial increase from 0.44 in 2018 to 0.49 in 2019, the ratio plateaued at 0.48 from 2020 through 2022. This stability suggests that the efficiency of asset utilization in generating revenue remained constant, regardless of the fluctuations in overall profitability.
- ROA Drivers and Disaggregation
- The two-component disaggregation reveals that the variations in ROA were driven almost exclusively by changes in the net profit margin rather than asset turnover. Because asset turnover remained flat at 0.48 for the majority of the period, the expansion of ROA from 4.98% in 2020 to 8.70% in 2022 is directly attributable to the 7.65 percentage point increase in the net profit margin during that same timeframe.

Four-Component Disaggregation of ROA
Based on: 10-K (reporting date: 2022-12-31), 10-K (reporting date: 2021-12-31), 10-K (reporting date: 2020-12-31), 10-K (reporting date: 2019-12-31), 10-K (reporting date: 2018-12-31).
The Return on Assets (ROA) demonstrates a trajectory of recovery and expansion over the analyzed five-year period. A notable decline occurred in 2020, where ROA dropped to its lowest point of 4.98%, followed by a sharp acceleration to a peak of 8.70% by December 31, 2022. This overall improvement is primarily attributed to operational efficiency and reduced financial friction rather than gains in asset utilization.
- EBIT Margin
- Operating profitability experienced a V-shaped trend, decreasing from 24.32% in 2018 to a trough of 21.20% in 2020. This was followed by a substantial expansion, culminating in a five-year high of 27.89% in 2022, serving as a primary driver for the overall increase in ROA.
- Interest Burden
- The interest burden ratio fluctuated significantly, reaching a low of 0.63 in 2020, indicating a higher relative impact of interest expenses on earnings. A strong recovery followed, with the ratio climbing to 0.86 by 2022, reflecting a reduction in the relative weight of interest obligations relative to operating income.
- Asset Turnover
- Asset efficiency remained largely stagnant after an initial increase between 2018 (0.44) and 2019 (0.49). For the subsequent three years, the ratio remained constant at 0.48, suggesting that the recent growth in ROA was not driven by increased revenue generation per unit of asset.
- Tax Burden
- The tax burden remained relatively stable throughout the period, oscillating narrowly between 0.74 and 0.78. This consistency indicates that changes in the net ROA were not significantly influenced by fluctuations in the effective tax rate.
The synthesis of these components reveals that the increase in ROA since 2020 is the result of the combined positive effects of expanded operating margins and a lower relative interest burden, while asset productivity remained neutral.

Disaggregation of Net Profit Margin
Based on: 10-K (reporting date: 2022-12-31), 10-K (reporting date: 2021-12-31), 10-K (reporting date: 2020-12-31), 10-K (reporting date: 2019-12-31), 10-K (reporting date: 2018-12-31).
The net profit margin exhibited a U-shaped trajectory over the five-year period, declining from 13.62% in 2018 to a trough of 10.43% in 2020, before recovering sharply to reach a peak of 18.08% by 2022. This evolution is the result of fluctuating operational efficiency and varying financing burdens, with the most significant expansion occurring between 2020 and 2022.
- EBIT Margin
- Operating profitability followed a pattern similar to the net profit margin, experiencing a contraction from 24.32% in 2018 to 21.20% in 2020. However, a strong recovery followed, with the margin expanding to 27.89% in 2022. This suggests that the overall increase in net profitability was heavily driven by improved operational performance and cost management.
- Interest Burden
- The interest burden ratio showed a notable decline reaching its lowest point of 0.63 in 2020, indicating a higher relative impact of interest expenses on operating income during that period. Subsequently, the ratio improved steadily, rising to 0.86 by 2022, which reflects a reduced relative cost of debt and improved interest coverage.
- Tax Burden
- The tax burden remained relatively stable throughout the analyzed period, fluctuating within a narrow range between 0.74 and 0.78. Because these values showed minimal variance, the tax burden was not a primary driver of the volatility observed in the net profit margin.
The disaggregation of the net profit margin indicates that the substantial growth observed in 2021 and 2022 was a dual result of expanded operating margins and a decreased relative interest burden. The convergence of higher EBIT margins and a stronger interest burden ratio significantly amplified the bottom-line profitability by the end of the period.
