Pfizer Inc. (NYSE:PFE)

The analysis of the return on equity (ROE) reveals a period of significant volatility, characterized by a sharp decline from 2022 peaks followed by a partial recovery through 2025 and a subsequent softening in 2026.

Return on Assets (ROA)

A strong performance is observed throughout 2022, with ROA peaking at 15.91% by December 31, 2022. This was followed by a sustained downward trajectory through 2023 and early 2024, with the ratio entering negative territory and reaching a low of -1.20% by June 30, 2024. A recovery phase began in the second half of 2024, with ROA stabilizing and oscillating between 1.97% and 5.22% throughout 2025 and 2026.

Financial Leverage

Financial leverage remained relatively stable across the analyzed period, oscillating within a narrow range between 1.94 and 2.54. A marginal peak in leverage occurred on December 31, 2023, coinciding with the period of lowest asset profitability. In the latter half of the period, the leverage ratio remained consistent, generally fluctuating between 2.25 and 2.41.

Return on Equity (ROE) Synthesis

The volatility in ROE is primarily driven by fluctuations in ROA rather than shifts in capital structure. The peak ROE of 33.61% in July 2022 was the result of high asset efficiency coupled with steady leverage. The subsequent contraction to a low of -2.96% in June 2024 was almost exclusively attributable to the collapse in ROA. While ROE recovered to a high of 12.12% by June 2025, a downward trend emerged toward the end of 2026, concluding the period at 4.53%.

The Return on Equity (ROE) exhibits significant volatility over the analyzed period, characterized by a sharp decline from peak levels in 2022 to negative territory in early 2024, followed by a partial recovery and a subsequent gradual decline through 2026. The overall trend indicates that the company experienced a severe compression in profitability and operational efficiency that was not sufficiently offset by financial leverage.

Net Profit Margin

The profit margin was the primary driver of ROE volatility. High initial margins ranging between 27.01% and 31.27% in 2022 collapsed precipitously, reaching a trough of -4.62% by June 30, 2024. While a recovery occurred in 2025, peaking at 16.84% in June, a downward trajectory resumed in the latter half of 2025 and throughout 2026, ending at 6.34%.

Asset Turnover

Operational efficiency showed a marked deterioration. Asset turnover decreased from a high of 0.52 in July 2022 to a low of 0.25 in March 2024. This represents a significant reduction in the ability to generate revenue from the asset base. A modest recovery is observed from late 2024 onward, with the ratio stabilizing between 0.30 and 0.32 by the end of the period.

Financial Leverage

Financial leverage remained the most stable component of the DuPont analysis, generally fluctuating between 1.94 and 2.54. A peak in leverage occurred in December 2023 at 2.54, coinciding with the period of lowest profitability, suggesting an increase in relative debt or a decrease in equity during the margin crisis. However, leverage did not experience a structural shift and remained consistently above 2.00.

The correlation between the Net Profit Margin and ROE is nearly absolute, confirming that profitability, rather than asset utilization or capital structure, was the dominant factor in the fluctuation of shareholder returns. The simultaneous dip in asset turnover and profit margin between 2022 and early 2024 suggests a period of operational contraction or significant external market headwinds. Although efficiency stabilized and margins recovered partially by 2025, the inability to sustain those gains resulted in a weakened ROE of 4.53% by September 2026.

The Return on Assets (ROA) exhibits a cyclical pattern characterized by an initial peak, a sharp contraction into negative territory, and a subsequent partial recovery that stabilizes at a significantly lower baseline than the initial period.

Net Profit Margin

Profitability demonstrated significant volatility, peaking at 31.27% in December 2022 before entering a steep decline. The margin plummeted to its lowest point of -4.62% by June 2024, reflecting a period of severe earnings compression. A recovery phase followed, with margins climbing back to a peak of 16.84% in June 2025, although a downward trend resumed toward the end of the period, ending at 6.34% in September 2026.

Asset Turnover

Efficiency in asset utilization showed a structural decline. From April 2022 to April 2023, the ratio remained relatively stable between 0.48 and 0.52. However, a contraction occurred throughout 2023, reaching a floor of 0.25 by March 2024. While there was a slight improvement and subsequent stabilization around the 0.30 to 0.32 range from December 2024 through September 2026, the ratio failed to return to its previous 2022 levels.

ROA Disaggregation and Drivers

The overall trajectory of the ROA is the result of the combined impact of margin compression and declining asset efficiency. The peak ROA of 15.91% in December 2022 was driven by the simultaneous optimization of both net profit margins and asset turnover. The subsequent decline to -1.20% in June 2024 was a dual-failure event where both components reached their nadirs. The modest recovery of ROA to between 2% and 5% in 2025 and 2026 was primarily fueled by the recovery in net profit margins, as the asset turnover ratio remained stunted, acting as a ceiling on the potential recovery of total asset returns.
