The Return on Equity (ROE) exhibits a cyclical pattern over the analyzed period, characterized by a peak in 2022 followed by a decline and a subsequent recovery by 2026. The two-component DuPont disaggregation reveals that fluctuations in ROE are predominantly driven by changes in operational efficiency, although financial leverage acted as a moderating factor during periods of profitability decline.

Return on Assets (ROA)

A peak in asset productivity is observed in 2022 at 12.57%, remaining relatively stable through 2023. A significant contraction occurs in 2024 and 2025, where ROA drops to 8.29% and 8.32%, respectively, indicating a diminished capacity to generate earnings from the asset base. A recovery trend emerges in 2026, with ROA rising to 10.23%.

Financial Leverage

The leverage ratio remained consistent between 2.30 and 2.36 from 2021 to 2023. A notable increase to 2.74 is observed in 2024, suggesting an increase in the use of debt or a reduction in equity to amplify returns during a period of operational weakness. This ratio moderately declines to 2.58 by 2026, indicating a slight stabilization of the capital structure.

Integrated ROE Analysis

The peak ROE of 29.70% in 2022 was primarily driven by strong ROA paired with stable leverage. Conversely, the decline in ROE to 21.73% by 2025 occurred despite the increase in financial leverage, as the amplification effect of the leverage ratio was insufficient to offset the marked decrease in ROA. The recovery to 26.38% in 2026 is primarily attributable to the rebound in asset profitability, confirming that operational performance is the primary driver of shareholder returns over the observed timeframe.

The Return on Equity (ROE) exhibited significant volatility over the observed six-year period, characterized by a peak in 2022 and a subsequent trough in 2025, before recovering in 2026. The fluctuations in ROE are the result of shifting dynamics across net profit margins, asset turnover, and financial leverage.

Net Profit Margin

Profitability trended upward initially, reaching a peak of 22.91% in 2022. This was followed by a consistent decline over the next three years, hitting a low of 17.97% in 2025. A recovery occurred in 2026, with the margin returning to 20.95%, suggesting a restoration of earnings efficiency relative to revenue.

Asset Turnover

Asset utilization improved steadily from 2021 to 2023, peaking at a ratio of 0.56. A sharp contraction was observed in 2024, where the ratio dropped to 0.43, indicating a temporary decline in the efficiency of asset employment to generate sales. A gradual recovery trend followed, with the ratio rising to 0.49 by 2026.

Financial Leverage

The leverage ratio remained stable between 2.30 and 2.36 from 2021 to 2023. A significant increase occurred in 2024, peaking at 2.74, which indicates an increased reliance on debt or a reduction in the equity base. Although leverage decreased slightly in 2025 and 2026, it remained at a higher plateau than the 2021-2023 period.

The decline in ROE during 2024 and 2025 was primarily driven by the concurrent deterioration of both net profit margins and asset turnover. While financial leverage increased during this window—which typically acts to amplify ROE—the magnitude of the decline in profitability and efficiency outweighed the effects of increased leverage. The rebound in ROE to 26.38% in 2026 is attributed to the synchronized recovery of profit margins and asset utilization.

Return on Equity (ROE) exhibited a non-linear trend over the analyzed period, peaking at 29.70% in July 2022 before declining to a low of 21.73% in July 2025. A recovery is observed by July 2026, with the ratio returning to 26.38%.

Operating Profitability

The EBIT Margin remained stable between 27.49% and 28.78% from 2021 to 2023. A notable contraction occurred in 2024 and 2025, with margins dipping to 24.61% and 22.40% respectively. A sharp reversal is evident in 2026, where the margin recovered to 27.60%, mirroring early-period levels.

Asset Efficiency

Asset Turnover experienced volatility, rising from 0.51 in 2021 to a peak of 0.56 in 2023. A significant decrease to 0.43 was recorded in 2024, followed by a gradual recovery to 0.49 by 2026, indicating fluctuating efficiency in utilizing assets to generate revenue.

Financial Leverage

Financial leverage remained consistent at approximately 2.30 to 2.36 between 2021 and 2023. An upward shift occurred in 2024, with the ratio peaking at 2.74. Although it moderated slightly to 2.58 by 2026, the overall increase in leverage suggests a greater reliance on debt to amplify equity returns during the latter half of the period.

Tax and Interest Burdens

The tax burden remained largely stable between 0.80 and 0.84, with a temporary spike to 0.92 in 2025, implying a period of lower relative tax impact on earnings. The interest burden remained high and stable near 0.97 through 2023 but declined to 0.87 in 2025, signaling a temporary increase in the cost of debt relative to EBIT before recovering to 0.92 in 2026.

The Return on Assets (ROA) exhibits a cyclical pattern over the analyzed six-year period, characterized by an initial peak, a significant contraction, and a subsequent recovery. ROA increased from 10.86% in 2021 to a peak of 12.57% in 2022, followed by a sharp decline to 8.29% by 2024. A stabilization period occurred in 2025, with a notable recovery to 10.23% by 2026.

Net Profit Margin

Profitability margins demonstrated volatility, peaking at 22.91% in 2022 before entering a downward trend that reached a low of 17.97% in 2025. This compression suggests a period of increased operating costs or pricing pressure. However, a strong recovery is evident in 2026, where the margin returned to 20.95%, nearly reaching 2021 levels.

Asset Turnover

Asset efficiency improved steadily between 2021 and 2023, rising from 0.51 to a peak of 0.56. A substantial decline occurred in 2024, with the ratio dropping to 0.43, indicating a decrease in the company's ability to generate revenue from its asset base. Since 2024, a gradual upward trajectory has been observed, with the ratio recovering to 0.49 by 2026.

ROA Component Interaction

The decline in ROA between 2023 and 2024 was a dual-driven event, resulting from the simultaneous erosion of both profit margins and asset turnover. The trough in ROA observed in 2024 and 2025 reflects the combined impact of lower operational efficiency and reduced profitability. The rebound in 2026 is primarily attributed to the restoration of net profit margins coupled with a steady improvement in asset utilization.

The Return on Assets (ROA) exhibited a fluctuating trend over the observed six-year period, peaking at 12.57% in 2022 before experiencing a significant contraction to a low of 8.29% in 2024. A recovery phase is evident by 2026, with ROA ascending to 10.23%. This volatility is the result of varying contributions from operational efficiency, asset utilization, and financial burdens.

EBIT Margin

The operational profitability showed a steady decline between 2022 and 2025, dropping from a peak of 28.78% to a low of 22.40%. This downward trajectory was a primary driver of the overall ROA compression during this period. However, a sharp reversal occurred in 2026, with the margin rebounding to 27.60%, suggesting a successful restoration of operational efficiency or a shift in cost structures.

Asset Turnover

Asset utilization efficiency peaked in 2023 at a ratio of 0.56 before declining sharply to 0.43 in 2024. This indicates a period of diminished revenue generation per unit of asset. While the ratio began a gradual recovery in 2025 (0.46) and 2026 (0.49), it remained below the 2022-2023 levels, suggesting that asset productivity has not fully returned to its previous peak.

Interest Burden

The interest burden remained relatively stable near 0.97-0.98 until 2024, after which it declined to a low of 0.87 in 2025. This decline indicates that interest expenses consumed a larger portion of operating income during the 2024-2025 window, adding further downward pressure on the net return. The ratio improved to 0.92 by 2026.

Tax Burden

The tax burden exhibited an inverse relationship with the other components, generally trending upward from 0.80 in 2021 to a peak of 0.92 in 2025. This increase suggests a lower effective tax rate during the years when operational margins and asset turnover were weakest, which served to partially mitigate the decline in ROA.

The analysis indicates that the decline in ROA between 2023 and 2025 was primarily driven by a simultaneous erosion of EBIT margins and asset turnover, compounded by an increasing interest burden. The recovery observed in 2026 is predominantly attributed to the strong rebound in the EBIT margin, which offset the continued moderate recovery in asset turnover.

The net profit margin exhibits a cyclical trajectory over the analyzed period, characterized by a peak in 2022, a sustained contraction through 2025, and a subsequent recovery in 2026. The volatility in the final bottom-line margin is primarily driven by fluctuations in operating efficiency, though it is further influenced by shifting tax and interest burdens.

Net Profit Margin Trends

The net profit margin rose from 21.26% in 2021 to a peak of 22.91% in 2022. Following this peak, a downward trend emerged, with the margin declining to 19.18% in 2024 and reaching a period low of 17.97% in 2025. A significant recovery is observed in 2026, where the margin returns to 20.95%.

Operating Profitability (EBIT Margin)

The EBIT margin serves as the primary driver for the net profit margin's movements. Operating profitability remained strong between 2021 and 2023, peaking at 28.78% in 2022. However, a marked deterioration in operating efficiency occurred between 2023 and 2025, with the margin falling to 22.40%. This contraction suggests a rise in operating expenses or a decline in gross margins during this window. The recovery to 27.60% in 2026 indicates a restoration of operational efficiency.

Tax Burden Analysis

The tax burden ratio showed a general upward trend from 0.80 in 2021 to a peak of 0.92 in 2025. This increase indicates a reduction in the effective tax rate over time, which acted as a partial cushion against the declining EBIT margins during the mid-period slump.

Interest Burden Analysis

The interest burden remained highly stable near 0.97-0.98 through 2023, suggesting minimal impact from financing costs. A decline occurred in 2024 (0.92) and 2025 (0.87), signifying that interest expenses consumed a larger portion of operating income during these years. The ratio returned to 0.92 in 2026, reflecting a moderation of the interest expense impact.

In synthesis, the decline in net profitability between 2023 and 2025 was caused by a combination of compressing operating margins and an increased interest burden, which outweighed the positive impact of a decreasing effective tax rate. The restoration of the net profit margin in 2026 is directly attributable to the recovery of the EBIT margin to historical levels.
