Pfizer Inc. (NYSE:PFE)

The Return on Equity (ROE) exhibits significant volatility over the observed period, characterized by a precipitous decline from 2022 peaks, a period of negative returns in early 2024, and a partial recovery that softens toward mid-2026.

Return on Assets (ROA) Trends

ROA serves as the primary driver of the fluctuations in overall profitability. A strong start is observed in 2022, with values peaking at 15.91% in December. This was followed by a sharp contraction, with ROA falling into negative territory by March 2024 and reaching a trough of -1.20% in June 2024. A recovery phase emerged in the latter half of 2024 and first half of 2025, peaking at 5.22% in June 2025, before trending downward to 2.15% by June 2026.

Financial Leverage Stability

The financial leverage ratio remained relatively stable throughout the analysis period, fluctuating within a range of 1.94 to 2.54. While leverage increased slightly during the period of deepest asset underperformance—reaching 2.54 in December 2023—it did not exhibit a strong enough trend to independently offset the volatility of the asset returns.

ROE Disaggregation and Synthesis

The two-component disaggregation reveals that the volatility in ROE is almost entirely attributable to changes in ROA rather than shifts in capital structure. ROE peaked at 33.61% in July 2022, mirroring the strength of the asset returns. The subsequent collapse to -2.96% in June 2024 was a direct result of the negative ROA. The recovery to 12.12% in June 2025 was driven by the rebound in operational asset efficiency, as the leverage ratio remained consistent with historical averages. The period ends with a diminishing ROE of 5.09%, corresponding with the decline in ROA.

The Return on Equity (ROE) exhibits significant volatility over the analyzed period, characterized by a sharp contraction from a peak of 33.61% in July 2022 to a trough of -2.96% in June 2024. A moderate recovery followed, with ROE peaking again at 12.12% in June 2025, before entering a gradual decline to 5.09% by June 2026. This trajectory indicates a period of severe earnings instability driven primarily by fluctuations in operational profitability and asset efficiency.

Net Profit Margin

Profitability served as the primary driver of ROE volatility. The margin remained strong through 2022, peaking at 31.27% in December. However, a precipitous decline occurred throughout 2023 and early 2024, with margins falling into negative territory, reaching a low of -4.62% in June 2024. While a recovery phase ensued, with margins climbing back to 16.84% by June 2025, a subsequent downward trend is observed through June 2026, ending at 6.80%.

Asset Turnover

Asset utilization efficiency shows a consistent long-term decline. The ratio started at 0.50 in April 2022 and steadily decreased to a minimum of 0.25 by March 2024. Following this low point, the turnover ratio stabilized, fluctuating within a narrow range between 0.26 and 0.32 from June 2024 through June 2026. This suggests that the company failed to return to its previous levels of asset productivity despite the recovery in profit margins.

Financial Leverage

Financial leverage remained the most stable component of the DuPont analysis, generally oscillating between 1.94 and 2.54. A slight increase in leverage was observed during the period of lowest profitability, peaking at 2.54 in December 2023. While leverage provided a consistent multiplier effect, it was insufficient to offset the combined impact of declining margins and reduced asset turnover during the downturn.

The synthesis of these components reveals that the collapse in ROE during 2023 and early 2024 was a result of a simultaneous decline in both profit margins and asset turnover. The subsequent partial recovery in 2025 was driven almost exclusively by a rebound in the net profit margin, as asset turnover remained suppressed relative to 2022 levels. The final downward trend in ROE toward mid-2026 is attributed to the renewed erosion of the net profit margin.

The Return on Assets (ROA) exhibits a highly volatile trajectory characterized by a period of strength in 2022, a severe contraction throughout 2023 and early 2024, and a subsequent partial recovery that trended downward toward mid-2026. The two-component disaggregation reveals that while both profitability and asset efficiency declined, the primary driver of the ROA volatility was the net profit margin.

Net Profit Margin

Profitability peaked in late 2022, reaching 31.27% by December 31, 2022. A sharp and sustained decline followed throughout 2023, with margins dropping to 3.56% by the end of that year. This downward momentum led to negative margins in the first half of 2024, bottoming at -4.62% in June 2024. A recovery phase was observed from late 2024 through mid-2025, where margins peaked at 16.84% in June 2025, before entering another gradual decline to 6.80% by June 2026.

Asset Turnover

Operational efficiency remained stable and relatively high during 2022, fluctuating between 0.50 and 0.52. A significant contraction occurred throughout 2023, with the ratio falling to 0.26 by December 31, 2023. From early 2024 through June 2026, the asset turnover ratio remained stagnant, oscillating within a narrow range of 0.25 to 0.32. This indicates a structural shift in asset productivity that did not recover in tandem with the profit margin.

Return on Assets (ROA) Synthesis

The ROA mirrored the collapse of the net profit margin, falling from a peak of 15.91% in December 2022 to a trough of -1.20% in June 2024. The subsequent rebound in ROA, which reached a secondary peak of 5.22% in June 2025, was driven exclusively by the recovery in profit margins, as asset turnover provided no meaningful contribution to the increase. The final observed trend shows a decline in ROA to 2.15% by June 2026, reflecting the renewed compression of profit margins.
