An analysis of the two-component DuPont disaggregation reveals a distinct shift in financial performance beginning in the second quarter of 2024. The return on equity (ROE) transitioned from a period of stability and growth to a sustained decline, primarily driven by a deterioration in asset productivity rather than shifts in capital structure.

Return on Assets (ROA)

A period of stability and gradual improvement is observed from April 2022 through March 2024, with ROA peaking at 18.36% in December 2023. However, a significant contraction occurred starting in June 2024, where the ratio dropped to 14.61% and reached a low of 9.68% by March 2026. This indicates a marked decrease in the efficiency of asset utilization or a compression in net profit margins during the latter half of the observed timeframe.

Financial Leverage

The leverage ratio remained relatively stable throughout the period, fluctuating between a minimum of 1.59 and a maximum of 2.01. A peak in leverage was noted in September 2024 at 2.01, which coincided with the initial decline in asset returns. Because the leverage ratio remained within a consistent range, it did not serve as a primary driver for the overall change in equity returns.

Return on Equity (ROE)

ROE closely mirrored the trajectory of ROA, maintaining a strong range between 26.96% and 30.93% from April 2022 to March 2024. A sharp downward trend emerged in mid-2024, with ROE falling to 24.77% in June and continuing to decline to a low of 17.85% in March 2026. The data suggests that the stability of the financial leverage ratio was insufficient to offset the weakening ROA, resulting in a net reduction in returns to shareholders.

The Return on Equity (ROE) exhibited a period of relative strength and stability between April 2022 and March 2024, peaking at 30.93% in December 2022. However, a consistent downward trajectory is observed starting in the second quarter of 2024, with ROE reaching a minimum of 17.85% by March 2026, before a modest recovery to 20.09% in June 2026.

Net Profit Margin

Profitability remained stable throughout 2022 and 2023, generally oscillating between 22.86% and 25.46%. A peak of 25.68% was reached in March 2024. Subsequently, a contraction occurred, with margins dipping to a low of 19.88% in June 2025. A recovery trend emerged in the final quarters of the analysis, returning to 23.61% by June 2026.

Asset Turnover

The most pronounced decline is visible in asset efficiency. Between April 2022 and March 2024, asset turnover remained consistently between 0.69 and 0.75. A sharp decrease began in June 2024 (0.58) and persisted through March 2026, where it hit a low of 0.46. This trend indicates a significant reduction in the company's ability to generate revenue relative to its asset base.

Financial Leverage

Financial leverage remained the most stable of the three DuPont components. While it fluctuated between 1.59 and 1.87 during the initial years, a peak of 2.01 occurred in September 2024. Throughout the period of ROE decline in 2025 and 2026, leverage remained relatively constant, ranging between 1.76 and 1.90, suggesting that the erosion of shareholder returns was not caused by a reduction in financial gearing.

The overall decomposition of ROE indicates that the deterioration in shareholder returns was primarily driven by a substantial drop in asset turnover, which was further exacerbated by a temporary contraction in net profit margins during 2025. The relative stability of financial leverage provided a minor buffer but was insufficient to counteract the operational efficiency losses.

The Return on Equity (ROE) exhibited a period of stability and moderate growth between April 2022 and December 2023, peaking at 30.93% in December 2022 and maintaining levels above 29% through March 2024. However, a sustained downward trajectory followed, with ROE falling to a low of 17.85% by March 2026, before a slight recovery to 20.09% in June 2026. This overall decline in equity returns is the result of divergent trends between operational profitability and asset efficiency.

Operational Profitability and Tax Impact

The EBIT Margin demonstrated a consistent upward trend, rising from 28.31% in April 2022 to 33.39% by June 2026. This indicates an improvement in core operating efficiency and pricing power. The Interest Burden remained remarkably stable, fluctuating only slightly between 0.98 and 0.93, suggesting that interest expenses have not been a significant driver of volatility in net income. Conversely, the Tax Burden showed a gradual decline from 0.85 in early 2022 to a range of 0.72 to 0.76 in the later periods, indicating a higher effective tax rate that exerted downward pressure on the final ROE.

Asset Utilization and Financial Leverage

A significant contraction in Asset Turnover is the primary driver of the declining ROE. This ratio remained relatively stable between 0.69 and 0.75 until June 2024, after which it dropped sharply, reaching a low of 0.46 by March 2026. This trend suggests that the growth in the asset base has significantly outpaced the growth in generated revenue. Financial Leverage increased from 1.59 in April 2022 to a peak of 2.01 in September 2024, eventually stabilizing around 1.76 to 1.90. While the increase in leverage provided a partial offset to the falling asset turnover, it was insufficient to maintain the historical ROE levels.

Synthesis of ROE Decomposition

The analysis reveals a structural shift in the drivers of return. The decline in ROE was not caused by operational failure—as EBIT margins improved—but was instead driven by a substantial decrease in asset turnover and an increasing tax burden. The company's ability to generate profit per unit of sale improved, but its ability to generate sales per unit of asset diminished significantly starting in mid-2024, leading to the observed erosion in equity returns.

The Return on Assets (ROA) exhibited a period of relative stability and growth from April 2022 through March 2024, fluctuating between a low of 15.80% and a peak of 18.36%. A significant downward shift occurred starting in June 2024, with ROA dropping to 14.61% and further declining to 11.34% by September 2024. For the remainder of the observed period, ROA stabilized at a lower threshold, ranging between 9.68% and 12.00%.

Net Profit Margin Trends

Profitability remained resilient through the first half of the analysis, maintaining a range between 22.86% and 25.68%, with a peak achieved in March 2024. A gradual contraction followed, with margins declining to a low of 19.88% by June 2025. However, a recovery trend emerged in the latter part of the period, with the margin returning to 23.61% by June 2026.

Asset Turnover Dynamics

Asset utilization was consistent from April 2022 to March 2024, holding steady between 0.69 and 0.75. A sharp decline in efficiency was observed in June 2024, where the ratio fell to 0.58, eventually reaching a period low of 0.46 in March 2026. This suggests a substantial increase in the asset base relative to revenue generation or a decrease in the effectiveness of asset deployment.

DuPont Disaggregation Analysis

The overall reduction in ROA is primarily driven by the deterioration of asset turnover rather than a collapse in profitability. While the decline in net profit margins during 2025 contributed to the lower ROA, the most abrupt decline in ROA during 2024 directly coincides with the collapse in asset turnover. The subsequent stabilization of ROA indicates that the lower asset turnover became the dominant factor limiting overall asset productivity, despite the eventual recovery of profit margins toward 2026 levels.

The Return on Assets (ROA) exhibited a period of relative stability and growth from April 2022 through December 2023, peaking at 18.36%. However, a significant downward shift occurred beginning in June 2024, with ROA declining to a range between 9.68% and 12.00% through June 2026. This overall decline in asset profitability is not primarily driven by operational inefficiency, but rather by a substantial contraction in asset utilization.

Tax Burden

A general downward trend is observed in the tax burden ratio, which decreased from a high of 0.85 in early 2022 to a low of 0.72 in mid-2025, before recovering slightly to 0.76 by June 2026. This suggests an increase in the effective tax rate over the analyzed period, which has acted as a moderate headwind to the final ROA.

Interest Burden

The interest burden remained remarkably stable, maintaining values between 0.98 and 0.93. The marginal decline over time indicates that interest expenses have had a negligible impact on the overall reduction of ROA, suggesting a well-managed debt profile or low leverage relative to earnings.

EBIT Margin

Operational profitability demonstrated resilience and overall growth. The EBIT margin expanded from 28.31% in April 2022 to 33.39% by June 2026. Despite a temporary dip in early 2025, the upward trajectory of the margin indicates that the core business became more efficient at converting revenue into operating profit.

Asset Turnover

Asset turnover is identified as the primary driver of the ROA decline. After remaining stable between 0.69 and 0.75 for two years, the ratio experienced a sharp decline starting in June 2024 (0.58), reaching a low of 0.46 in March 2026. This suggests that the asset base grew at a significantly faster rate than the revenue it generated, leading to a marked decrease in asset efficiency.

In summary, the deterioration of the ROA was caused by a divergence between operational performance and asset efficiency. While the EBIT margin improved, indicating stronger profitability per dollar of sales, the substantial drop in asset turnover outweighed these gains, pulling the overall return on assets downward.

An analysis of the disaggregated net profit margin reveals a complex interplay between operational efficiency, tax obligations, and financing costs over the observed period.

EBIT Margin Trends

Operational profitability demonstrated a general upward trajectory, starting at 28.31% in April 2022 and reaching a peak of 33.39% by June 2026. A period of sustained strength was observed between December 2023 and March 2024, where margins exceeded 32%. Despite a temporary contraction to 29.84% in March 2025, the metric recovered strongly in the subsequent quarters, indicating robust core operational performance.

Tax Burden Analysis

The tax burden ratio exhibited a gradual decline from 0.85 in April 2022 to a low of 0.72 in mid-2025. This downward trend indicates an increase in the effective tax rate, which exerted significant downward pressure on the net profit margin. The tax burden remained suppressed throughout 2025 before showing a slight recovery to 0.76 by June 2026.

Interest Burden Assessment

The interest burden remained consistently high and stable, fluctuating minimally between 0.98 and 0.93. This indicates that interest expenses have a negligible impact on the conversion of operating income to net income, suggesting a conservative leverage profile or highly manageable debt service requirements relative to earnings.

Net Profit Margin Synthesis

The net profit margin fluctuated between a high of 25.68% in March 2024 and a low of 19.88% in June 2025. The divergence between the EBIT margin and the net profit margin during 2025 highlights that the contraction in bottom-line profitability was driven primarily by the deteriorating tax burden rather than a collapse in operational efficiency. By June 2026, the net profit margin returned to 23.61%, supported by the period's peak EBIT margin.
