The Return on Equity (ROE) exhibits a distinct cyclical pattern over the observed period, characterized by an initial decline followed by a recovery phase. ROE began at a peak of 73.28% in September 2021, declined to a trough of 42.06% by December 2023, and subsequently recovered to a secondary peak of 63.38% in March 2026 before settling at 58.26% in June 2026.

Return on Assets (ROA)

ROA served as the primary driver of the fluctuations in ROE. The metric remained relatively stable around 27% through mid-2022 before entering a downward trend that bottomed at 18.41% in December 2023. A robust recovery followed, with ROA expanding consistently from 2024 through early 2026, eventually surpassing initial levels to reach a maximum of 32.26% in March 2026. This indicates a significant improvement in operational profitability relative to the asset base during the latter half of the period.

Financial Leverage

In contrast to the volatility of ROA, financial leverage exhibited a persistent and gradual downward trend. Starting at a ratio of 2.67 in September 2021, the leverage decreased steadily to 1.89 by June 2026. This consistent deleveraging indicates a strategic reduction in the reliance on debt to finance assets or a substantial increase in the equity base.

Two-Component Interaction

The analysis reveals two distinct phases in the ROE trajectory. During the initial decline (2021–2023), the contraction in ROE was exacerbated by the simultaneous decline in both operational efficiency (ROA) and financial leverage, creating a compounding negative effect. During the recovery phase (2024–2026), the expansion of ROE was driven exclusively by the growth in ROA, which was strong enough to offset the continued drag created by the declining financial leverage ratio.

The Return on Equity (ROE) exhibits a cyclical trajectory over the analyzed period, characterized by a significant contraction followed by a steady recovery. From a peak of 75.35% in March 2022, ROE declined to a trough of 42.06% by December 2023. Subsequently, a recovery phase emerged, with ROE climbing back to 63.38% by March 2026, before a slight moderation to 58.26% in June 2026.

Net Profit Margin

Profitability remained relatively stable during the first half of the period, hovering around 27%. A gradual decline was observed through 2023, reaching a low of 24.15% in December 2023. However, from March 2024 onward, there is a consistent upward trend in margins, culminating in a peak of 31.27% by June 2026. This indicates an improving ability to convert revenue into actual profit over the latter half of the timeframe.

Asset Turnover

Asset efficiency experienced a notable decline, falling from approximately 1.01 in late 2021 to a minimum of 0.76 in December 2023. This suggests a period of decreased asset productivity or an increase in the asset base that outpaced revenue growth. A recovery trend began in 2024, with the ratio returning to 1.04 by March 2026, reflecting an improvement in the efficiency of asset utilization to generate sales.

Financial Leverage

A sustained deleveraging trend is evident throughout the entire period. Financial leverage decreased from a high of 2.75 in March 2022 to 1.89 by June 2026. The consistent reduction in this ratio indicates a strategic shift toward a more conservative capital structure, reducing the company's reliance on debt to finance its assets.

Integrated DuPont Analysis

The decline in ROE between 2022 and 2023 was a multi-factor result of contracting asset turnover and reducing financial leverage, which outweighed the relatively stable profit margins. Conversely, the ROE recovery observed from 2024 to 2026 was primarily driven by significant expansions in net profit margin and the recovery of asset turnover. Notably, this ROE growth was achieved despite the continuing downward trend in financial leverage, suggesting that the improvement in equity returns is based on fundamental operational efficiency and profitability rather than increased financial risk.

The Return on Assets (ROA) exhibits a cyclical pattern, characterized by a period of significant contraction followed by a robust recovery and expansion. From a peak of 27.51% in December 2021, ROA declined to a trough of 18.41% by December 2023, before ascending to a peak of 32.26% in March 2026.

Net Profit Margin

Profitability remained relatively stable between 26% and 28% from September 2021 through September 2023. A downward trend emerged toward the end of 2023, reaching a minimum of 24.15% in December. Subsequently, a consistent upward trajectory is observed, with margins expanding to 31.27% by June 2026, suggesting improved cost management or pricing power in the latter half of the period.

Asset Turnover

Asset efficiency experienced a more pronounced decline than profit margins. After maintaining a ratio near 1.00 during 2021 and early 2022, the turnover ratio deteriorated steadily, reaching a low of 0.76 in December 2023. This indicates a period of underutilization of assets or significant asset growth that outpaced revenue generation. A recovery phase followed, with the ratio returning to and briefly exceeding its baseline, peaking at 1.04 in March 2026.

ROA Disaggregation and Interaction

The contraction in ROA between 2022 and 2023 was driven by a dual decline in both profitability and asset efficiency, with the deterioration in asset turnover acting as the primary catalyst for the decline. The subsequent recovery in ROA was similarly dual-driven; however, the expansion of the net profit margin provided a stronger tailwind in the final quarters, allowing ROA to surpass its initial 2021 levels despite asset turnover remaining slightly below its historical peak in the final quarter.
