Eli Lilly & Co. (NYSE:LLY)

The period under review demonstrates fluctuating performance in key financial metrics. Return on Assets (ROA) initially increased before declining and then exhibiting substantial growth. Financial Leverage showed a decreasing trend overall, with some interim increases. Return on Equity (ROE) mirrored the ROA trend, initially decreasing before a significant upswing.

Return on Assets (ROA)

ROA increased from 11.44% in 2021 to 12.62% in 2022, indicating improved asset utilization efficiency. A subsequent decline to 8.19% in 2023 suggests a weakening in profitability relative to assets. However, ROA experienced a strong recovery, rising to 13.45% in 2024 and further to 18.35% in 2025, demonstrating a substantial improvement in asset profitability.

Financial Leverage

Financial Leverage decreased from 5.44 in 2021 to 4.65 in 2022, suggesting a reduction in the company’s reliance on debt financing. An increase to 5.94 in 2023 indicates a renewed use of leverage. It then decreased slightly to 5.55 in 2024 before falling to 4.24 in 2025, representing the lowest level of leverage observed during the period. This suggests a trend towards more conservative capital structure management in the later years.

Return on Equity (ROE)

ROE began at 62.16% in 2021 and decreased to 58.64% in 2022, mirroring the initial fluctuations in ROA and leverage. A more pronounced decline to 48.65% in 2023 reflects the impact of lower ROA. ROE then increased significantly to 74.62% in 2024 and continued to rise to 77.78% in 2025, driven by the substantial improvement in ROA and, to a lesser extent, the stabilization of financial leverage. The increase in ROE suggests improved returns for shareholders.

The interplay between ROA and Financial Leverage is evident in the ROE figures. While leverage initially contributed to higher ROE, its subsequent decrease, coupled with the ROA decline in 2023, resulted in lower overall returns. The strong ROA recovery in 2024 and 2025, however, more than offset the impact of decreasing leverage, leading to substantial gains in ROE.

The period under review demonstrates fluctuating performance across key financial ratios impacting overall Return on Equity (ROE). Net Profit Margin, Asset Turnover, and Financial Leverage all exhibit distinct trends that contribute to the observed changes in ROE.

Net Profit Margin

Net Profit Margin increased from 19.71% in 2021 to 21.88% in 2022, indicating improved profitability. However, it subsequently decreased to 15.36% in 2023 before rebounding significantly to 23.51% in 2024 and reaching a high of 31.67% in 2025. This suggests increasing efficiency in managing costs and generating profit from sales in the later years of the period.

Asset Turnover

Asset Turnover remained relatively stable between 2021 and 2023, fluctuating around 0.58 and 0.53. A slight increase to 0.57 was observed in 2024, followed by a return to 0.58 in 2025. This indicates a consistent, though not dramatically changing, efficiency in utilizing assets to generate sales.

Financial Leverage

Financial Leverage decreased from 5.44 in 2021 to 4.65 in 2022, suggesting a reduction in the use of debt financing. It then increased to 5.94 in 2023, decreased slightly to 5.55 in 2024, and further decreased to 4.24 in 2025. These fluctuations indicate a changing appetite for, and availability of, debt financing.

Return on Equity (ROE)

ROE initially decreased from 62.16% in 2021 to 58.64% in 2022. A more substantial decline was observed in 2023, with ROE falling to 48.65%. However, ROE experienced a significant recovery in 2024, reaching 74.62%, and continued to increase to 77.78% in 2025. The ROE trend closely follows the Net Profit Margin, suggesting that profitability is a primary driver of equity returns. The interplay between Net Profit Margin, Asset Turnover, and Financial Leverage explains the fluctuations in ROE throughout the period.

The substantial increase in ROE from 2023 to 2025 is primarily attributable to the significant improvement in Net Profit Margin, despite a concurrent decrease in Financial Leverage. The relatively stable Asset Turnover suggests that the increased profitability is not solely a result of more efficient asset utilization, but rather improved operational performance.

The five-component DuPont analysis reveals significant shifts in the company’s profitability and financial structure between 2021 and 2025. Return on Equity (ROE) experienced volatility, initially declining from 62.16% in 2021 to 48.65% in 2023, before a substantial recovery to 77.78% in 2025. This fluctuation is attributable to changes in the underlying components of the analysis.

Profitability (EBIT Margin)

The EBIT Margin demonstrated a notable increase over the period. Starting at 22.94% in 2021, it rose to a peak of 29.88% in 2024 and further increased to 40.85% in 2025. This suggests improving operational efficiency and pricing power. A dip to 20.63% in 2023 was observed, but the subsequent recovery indicates this was likely a temporary setback.

Asset Turnover

Asset Turnover remained relatively stable, fluctuating between 0.53 and 0.58 throughout the analyzed period. A slight decrease was noted in 2023, followed by a return to the 2021 level in 2024 and 2025. This indicates consistent efficiency in utilizing assets to generate sales, with no significant improvements or deteriorations.

Financial Leverage

Financial Leverage exhibited a decreasing trend overall. It began at 5.44 in 2021, decreased to 4.65 in 2022, increased to 5.94 in 2023, and then decreased again to 4.24 in 2025. This suggests a shifting capital structure, with a move towards less reliance on debt financing, particularly in the later years of the period. The increase in 2023 may indicate a temporary increase in debt to fund operations or investments.

Tax Burden

The Tax Burden remained relatively high and stable, ranging from 0.80 to 0.92. A decrease to 0.80 was observed in 2023 and remained at that level in 2025, potentially reflecting changes in tax regulations or tax planning strategies. The impact of taxes on net income remained substantial throughout the period.

Interest Burden

The Interest Burden was consistently high, fluctuating between 0.93 and 0.97. This indicates a significant portion of pre-tax income is allocated to interest expenses. The slight increase in 2025, despite decreasing financial leverage, warrants further investigation to determine if changes in interest rates or debt composition contributed to this outcome.

The substantial increase in ROE from 2023 to 2025 is primarily driven by the significant improvement in EBIT Margin, partially offset by the decrease in Financial Leverage. The relatively stable Asset Turnover and Tax Burden suggest these factors had a limited impact on the overall ROE change. The consistent high Interest Burden continues to represent a drag on profitability.

The period under review demonstrates fluctuating performance in profitability and efficiency. Return on Assets (ROA) experienced both increases and decreases, driven by changes in Net Profit Margin and Asset Turnover. A detailed examination of these components reveals key insights into the company’s operational dynamics.

Net Profit Margin

Net Profit Margin exhibited an initial increase from 19.71% in 2021 to 21.88% in 2022. This was followed by a substantial decline to 15.36% in 2023. A recovery was then observed in 2024, with the margin rising to 23.51%, culminating in a significant increase to 31.67% in 2025. This indicates increasing profitability in the later years of the period, following a temporary dip.

Asset Turnover

Asset Turnover remained relatively stable between 2021 and 2023, consistently around 0.58 to 0.53. A slight increase to 0.57 was noted in 2024, followed by a return to 0.58 in 2025. This suggests consistent efficiency in utilizing assets to generate sales throughout the period, with minimal fluctuation.

Return on Assets (ROA)

ROA mirrored the trends in Net Profit Margin. An initial increase from 11.44% in 2021 to 12.62% in 2022 was followed by a decrease to 8.19% in 2023. The ROA then increased significantly to 13.45% in 2024 and further to 18.35% in 2025. The correlation between ROA and Net Profit Margin is strong, indicating that changes in profitability are the primary driver of ROA fluctuations, as Asset Turnover remained comparatively stable.

The decline in ROA in 2023 appears directly linked to the decrease in Net Profit Margin, despite consistent asset utilization. The subsequent recovery and strong growth in ROA in 2024 and 2025 are attributable to the substantial improvement in Net Profit Margin, with Asset Turnover providing a consistent contribution. Overall, the company’s ability to improve profitability has a significant impact on its overall asset performance.

The four-component disaggregation of Return on Assets (ROA) reveals notable shifts in performance over the five-year period. Overall, ROA demonstrates volatility, with an initial increase followed by a decline and subsequent recovery. This fluctuation is driven by changes in the underlying components of profitability and efficiency.

EBIT Margin

The EBIT Margin exhibits a significant upward trend, increasing from 22.94% in 2021 to a substantial 40.85% in 2025. However, there was a dip to 20.63% in 2023 before a strong rebound. This suggests improving operational profitability, though with some intermediate challenges. The substantial increase in the later years is a key driver of the overall ROA improvement.

Asset Turnover

Asset Turnover remains relatively stable, fluctuating between 0.53 and 0.58 throughout the period. A slight decrease is observed in 2023, followed by a return to the 2021 level in 2025. This indicates consistent, though not improving, efficiency in utilizing assets to generate revenue. The stability suggests that changes in ROA are not primarily attributable to asset utilization.

Tax Burden

The Tax Burden generally remains high, fluctuating around 0.80 to 0.92. A noticeable decrease to 0.80 is seen in 2023, followed by a slight increase in 2024 and a return to 0.80 in 2025. This suggests some variability in the effective tax rate, but overall a consistently significant portion of pre-tax profits is allocated to taxes.

Interest Burden

The Interest Burden is consistently high, ranging from 0.93 to 0.97. This indicates that a large proportion of earnings before interest and taxes is required to cover interest expenses. A slight increase is observed in 2025, potentially reflecting changes in debt levels or interest rates. The high and stable interest burden suggests a consistent reliance on debt financing.

The decline in ROA in 2023 appears to be primarily driven by the decrease in EBIT Margin, despite a slight decrease in Asset Turnover. The subsequent recovery in ROA from 2024 onwards is strongly correlated with the significant improvement in EBIT Margin, offsetting the relatively stable Asset Turnover and consistent Tax and Interest Burdens. The interplay between profitability and efficiency, as reflected in these components, is crucial to understanding the overall ROA performance.

The period under review demonstrates fluctuating performance across key profitability metrics. While net profit margin exhibits an overall positive trend from 2021 to 2025, the path is not linear, and is heavily influenced by changes in the EBIT margin. Both tax and interest burdens remain relatively stable, suggesting these are not primary drivers of the observed net profit margin variations.

Net Profit Margin

Net profit margin increased from 19.71% in 2021 to 21.88% in 2022, then decreased to 15.36% in 2023. A significant recovery is then observed, with the margin rising to 23.51% in 2024 and further to 31.67% in 2025. This indicates a strengthening of overall profitability in the latter years of the period, following a dip in 2023.

EBIT Margin

The EBIT margin mirrors the fluctuations in net profit margin, but with greater amplitude. It rose from 22.94% in 2021 to 25.01% in 2022, before declining to 20.63% in 2023. A substantial increase is then noted, reaching 29.88% in 2024 and 40.85% in 2025. The strong correlation between EBIT margin and net profit margin suggests that operational profitability is the dominant factor influencing overall net income.

Tax Burden

The tax burden remained consistently high, fluctuating between 0.80 and 0.92 throughout the period. It began at 0.91 in 2021, increased slightly to 0.92 in 2022, decreased to 0.80 in 2023, rose to 0.84 in 2024, and returned to 0.80 in 2025. These relatively small variations indicate a stable tax environment and suggest that changes in the effective tax rate did not significantly impact net profit margin.

Interest Burden

The interest burden also exhibited stability, ranging from 0.93 to 0.97. It started at 0.95 in 2021 and 2022, decreased to 0.93 in 2023, increased to 0.94 in 2024, and rose to 0.97 in 2025. Similar to the tax burden, the minimal fluctuations suggest that interest expenses did not materially affect net profit margin.

In conclusion, the primary driver of changes in net profit margin appears to be the EBIT margin. The consistent tax and interest burdens indicate that operational performance is the key determinant of profitability during this period. The substantial improvement in both EBIT and net profit margins in 2024 and 2025 warrants further investigation to understand the underlying factors contributing to this positive trend.
