Based on: 10-K (reporting date: 2024-12-31), 10-K (reporting date: 2023-12-31), 10-K (reporting date: 2022-12-31), 10-K (reporting date: 2021-12-31), 10-K (reporting date: 2020-12-31).

The analysis of the financial ratios over the five-year period reveals several key trends and variances in operational efficiency, liquidity, leverage, and profitability indicators.

Total Asset Turnover
Both reported and adjusted total asset turnover ratios show a fluctuating yet generally stable pattern. The figures decreased from approximately 0.52-0.53 in 2020 to around 0.46 in 2021, followed by a recovery and increase to about 0.54-0.57 in 2022 and 2023, concluding with a slight decrease in 2024 to about 0.55-0.56. This suggests a recovery in asset utilization efficiency after a dip in 2021.
Current Ratio
The reported and adjusted current ratios demonstrate an overall improving liquidity position from 2020 to 2024. Starting at near 1.02 in 2020, the ratios increased to a peak around 1.47-1.49 in 2022, then dipped somewhat but remained above 1.25 in 2023, ultimately rising again by 2024 to approximately 1.36-1.40. This indicates a generally enhanced ability to meet short-term obligations, despite minor fluctuations.
Debt to Equity Ratio
There is a clear declining trend in the debt to equity ratios from 2020 through 2022, with reported values dropping from 1.26 to 0.67 and adjusted values from 1.27 to 0.66, reflecting a reduced reliance on equity financing. However, slight increases in 2023 to around 0.93-0.96 and a decrease to about 0.80-0.84 in 2024 suggest some repositioning in the capital structure, though still below the 2020 levels.
Debt to Capital Ratio
The debt to capital ratios follow a consistent downward trajectory from about 0.56 in 2020 to a low of 0.40 in 2022 for both reported and adjusted data. The subsequent mild increases to approximately 0.46-0.49 in 2023 and 2024 imply cautious increases in debt within the capital base but maintaining relatively lower leverage compared to earlier years.
Financial Leverage
Financial leverage ratios demonstrate a falling trend in the initial years, with reported ratios declining from 3.62 in 2020 to 2.37 in 2022 and adjusted ratios from 3.46 to 2.26. A rebound in 2023 to roughly 2.78-2.84 followed by a decline in 2024 to nearly 2.51-2.53 reflects measured use of leverage with moderate variability.
Net Profit Margin
There is considerable volatility in net profit margins. Reported margins rose sharply from 14.72% in 2020 to a peak of 26.79% in 2021, then declined to around 24.49% in 2022 before a significant drop in 2023 to near 0.61%, followed by a recovery in 2024 to 26.68%. Adjusted margins display similar patterns with notable negative profitability in 2023 (-2.38%). This volatility suggests extraordinary or non-recurring factors impacting profitability during 2023.
Return on Equity (ROE)
ROE trends mirror those of net profit margin with strong performance in 2020-2022, peaking at about 34.17%-34.23% in 2021. A steep decline in 2023 to near zero or negative territory (-3.78% adjusted) indicates a challenging year from an equity profitability perspective, followed by a robust rebound in 2024 reaching levels above 35%, exceeding prior years' figures.
Return on Assets (ROA)
ROA confirms similar dynamics, with increasing returns from 7.72% in 2020 up to approximately 13.3% in 2022 (reported) and 13.59% adjusted in 2021, but substantially dropping to below 1% reported and negative adjusted returns in 2023. The recovery to around 14.6% in 2024 indicates a resumption of asset profitability post the downturn.

Overall, the data indicates a period of improving liquidity and asset utilization from 2020 through 2022, combined with decreasing leverage ratios, suggesting a more conservative financial structure. However, the significant dips in profitability measures during 2023, including net profit margin, ROE, and ROA, signal an extraordinary or adverse event impacting financial performance that year. The subsequent recovery in 2024 to near or above previous peaks demonstrates resilience and a return to favorable operating conditions. The financial leverage ratios and debt-related measures suggest careful management of capital structure throughout the period, aligning with the profit and efficiency trends observed.

Sales
Sales have demonstrated a consistent upward trend over the five-year period, increasing from $47,994 million in 2020 to $64,168 million in 2024. The growth rate appears steady, with a notable acceleration from 2021 to 2022 and continuous increases in subsequent years, indicating expanding revenue generation capacity.
Total Assets
Total assets increased from $91,588 million in 2020 to $117,106 million in 2024. The growth was most significant between 2020 and 2021, followed by moderate increases and a slight dip in 2023 before rising again in 2024. This suggests an overall expansion in the company's asset base, with some fluctuations reflecting possible asset revaluation or disposals.
Reported Total Asset Turnover
The reported total asset turnover ratio was 0.52 in 2020, declined to 0.46 in 2021, but then recovered to 0.54 in 2022 and improved further to 0.56 in 2023, slightly dipping to 0.55 in 2024. This pattern indicates an initial decrease in asset utilization efficiency followed by a gradual improvement, suggesting better management or more effective deployment of assets in recent years.
Adjusted Total Assets
The adjusted total assets closely mirror the trend of total assets, increasing from $90,861 million in 2020 to $114,434 million in 2024. Similar fluctuations are observed with slight decreases in 2023, signifying adjustments that align closely with reported asset valuations while smoothing out certain anomalies.
Adjusted Total Asset Turnover
The adjusted total asset turnover ratio follows a trend akin to the reported ratio, starting at 0.53 in 2020, dipping to 0.46 in 2021, and then increasing steadily to 0.57 by 2023 with a marginal decrease to 0.56 in 2024. This indicates consistent improvement in asset use efficiency when adjustments are considered, reinforcing the observation of enhanced operational effectiveness over the analyzed period.

The annual financial data reveals several notable trends across the periods from 2020 to 2024. Current assets demonstrate a generally upward trajectory, increasing from 27,764 million US dollars in 2020 to 38,782 million US dollars in 2024. This increase, however, is not entirely linear, as there is a minor decline in 2023 compared to 2022. Current liabilities experienced fluctuations, dropping to 23,872 million US dollars in 2021 compared to 27,327 million US dollars in 2020, then gradually rising through 2024 to reach 28,420 million US dollars. This pattern indicates some short-term variability in obligations that the company needs to address within a year.

The reported current ratio, which measures liquidity and the company’s ability to cover short-term liabilities with current assets, reflects an improvement over the period, rising from 1.02 in 2020 to a peak of 1.47 in 2022, followed by a slight decrease to 1.25 in 2023 before climbing again to 1.36 in 2024. This suggests an overall enhancement of the liquidity position, despite some volatility in the middle years.

Adjusted current assets, which likely exclude certain items for a more precise liquidity picture, show a consistent upward trend similar to that of reported current assets. Values increase from 27,931 million US dollars in 2020 to 39,711 million US dollars in 2024, again with a small dip in 2023. Correspondingly, the adjusted current ratio improves steadily from 1.02 in 2020 to 1.40 in 2024, slightly outperforming the reported current ratio each year.

Overall, the data indicates a strengthening liquidity position over the analyzed years, supported by growth in both current and adjusted current assets and a generally rising current ratio. The intermittent decreases in 2023 suggest some short-lived pressures on liquidity, but these are followed by recovery in the subsequent year. The company appears to maintain its ability to meet short-term obligations, with an improving buffer as reflected in adjusted metrics.

Current Assets
Increase from 27,764 to 38,782 million US dollars (2020 to 2024) with a slight dip in 2023.
Current Liabilities

Reported Current Ratio
Improved from 1.02 to a peak of 1.47 in 2022, then declined and rose again to 1.36 in 2024.
Adjusted Current Assets
Consistent rise from 27,931 to 39,711 million US dollars, mirroring the trend in reported current assets.
Adjusted Current Ratio
Steady improvement from 1.02 up to 1.40, maintaining a slightly more favorable liquidity position than the reported ratio.

The financial data reveals several key trends over the five-year period ending in 2024. Total debt exhibits fluctuations, initially increasing from 31,791 million US dollars in 2020 to 33,102 million in 2021, then decreasing to 30,691 million in 2022, followed by a rise to 35,055 million in 2023 and further to 37,111 million in 2024. This indicates a general upward trend in the company’s leverage in the last two years.

Total stockholders’ equity shows significant growth from 25,317 million US dollars in 2020 to 38,184 million in 2021, further increasing to 45,991 million in 2022. However, there is a notable decline to 37,581 million in 2023, followed by a recovery to 46,313 million in 2024, suggesting some volatility in equity levels but an overall upward trajectory.

The reported debt to equity ratio mirrors these movements, decreasing from 1.26 in 2020 to 0.87 in 2021 and further down to 0.67 in 2022, reflecting strengthening equity relative to debt. The ratio then increases to 0.93 in 2023 and declines again to 0.80 in 2024, which aligns with the observed equity fluctuations and debt increases during the same period.

Adjusted total debt follows a similar path to reported total debt, rising in 2021, falling in 2022, and then increasing consistently through 2023 and 2024. Adjusted total equity also trends upward from 2020 to 2022, experiences a dip in 2023, and recovers in 2024, comparable to the reported equity figures but with slightly higher magnitudes.

The adjusted debt to equity ratio decreases steadily from 1.27 in 2020 to 0.83 in 2021 and further to 0.66 in 2022, indicating improved equity coverage over debt during that period. It then increases sharply to 0.96 in 2023 before dropping again to 0.84 in 2024, revealing some volatility but maintaining a generally lower leverage ratio compared to the starting point.

Total Debt
Fluctuated moderately with an overall rising trend after 2022.
Total Equity
Experienced significant growth through 2022, a sharp decline in 2023, and partial recovery in 2024.
Debt to Equity Ratios (Reported and Adjusted)
Display a pattern of improvement (decreasing ratios) through 2022 followed by increased leverage in 2023 and some reversal of this impact in 2024.

Overall, the data suggests a period of equity growth and deleveraging from 2020 to 2022, followed by increased borrowing and equity decline in 2023, and subsequent partial recovery in equity and reduction in leverage by 2024. This pattern may reflect strategic financial management responses to internal or external factors influencing capital structure.

Debt Levels
The total debt exhibited moderate fluctuations over the five-year period, starting at 31,791 million US dollars in 2020. It experienced a slight increase in 2021 to 33,102 million, followed by a decline to 30,691 million in 2022. Subsequently, the debt rose again to reach 35,055 million in 2023 and further increased to 37,111 million by the end of 2024. A similar pattern is observed in adjusted total debt values, which mirror the reported debt trends but with slightly higher amounts consistently.
Capital Base
Total capital demonstrated an overall upward trend, beginning at 57,108 million US dollars in 2020 and increasing significantly to 71,286 million in 2021. The upward momentum continued into 2022, reaching 76,682 million, albeit followed by a decline to 72,636 million in 2023. The capital base expanded again in 2024, hitting 83,424 million. Adjusted total capital figures align with these movements, consistently exceeding reported capital amounts across the years.
Debt to Capital Ratios
The reported debt to capital ratio reflected notable variability. Initially, the ratio was relatively high at 0.56 in 2020, then declined through 2021 and 2022 to 0.46 and 0.40 respectively, indicating a reduction in leverage during this period. However, this ratio increased again in 2023 to 0.48 before decreasing to 0.44 in 2024. The adjusted debt to capital ratio follows a similar trajectory, slightly diverging with marginally different values but maintaining the same overall trend.
Summary of Trends
The data suggests an increasing capital base with some volatility in debt levels, leading to fluctuating leverage ratios. The reduction in debt to capital ratios from 2020 to 2022 suggests enhanced capital strength or debt management, while the subsequent rise in 2023 indicates a temporary increase in leverage, followed by a moderate improvement in 2024. The close alignment between reported and adjusted figures implies consistency in the measurement approach over time.

The financial data reveals several distinct trends over the five-year period from 2020 to 2024 regarding assets, equity, and leverage ratios.

Total assets
Total assets increased from 91,588 million USD in 2020 to 117,106 million USD in 2024. The growth was most pronounced between 2020 and 2021, followed by a more moderate increase through 2022. There was a slight decline in 2023 before rising again in 2024, indicating some fluctuations but an overall upward trend in asset base.
Total stockholders’ equity
Equity showed significant variation, rising sharply from 25,317 million USD in 2020 to 38,184 million USD in 2021, and reaching a peak of 45,991 million USD in 2022. However, there was a marked decline in 2023 to 37,581 million USD before recovering to 46,313 million USD in 2024. This suggests volatility in equity levels, with a notable dip in 2023 potentially reflecting extraordinary events or changes in retained earnings or other equity components.
Reported financial leverage
The reported financial leverage ratio steadily decreased from 3.62 in 2020 to 2.37 in 2022, indicating a reduction in reliance on debt or liabilities relative to equity during this period. Yet, leverage increased again to 2.84 in 2023 before falling to 2.53 in 2024. The temporary increase in leverage in 2023 corresponds with the decline in equity that year.
Adjusted total assets
The adjusted total assets follow a pattern similar to total assets but remain slightly lower each year, rising from 90,861 million USD in 2020 to 114,434 million USD in 2024. The general trend indicates growth with a small dip in 2023, mirroring the movement observed in unadjusted assets.
Adjusted total equity
Adjusted equity increased from 26,295 million USD in 2020 to 48,228 million USD in 2022, showing robust growth. It then declined sharply to 37,900 million USD in 2023, before partially rebounding to 45,651 million USD in 2024. This aligns with the pattern observed in total equity, pointing to underlying factors affecting adjusted equity similarly.
Adjusted financial leverage
Adjusted financial leverage ratio decreased consistently from 3.46 in 2020 to 2.26 in 2022, reflecting improved capitalization or less dependence on debt. This ratio increased to 2.78 in 2023, coinciding with the equity decline, then dropped again to 2.51 in 2024. The fluctuations confirm a temporary weakening in leverage metrics during 2023, followed by recovery.

In summary, the data presents a growth trajectory in assets and equity across the five years with a noticeable dip in equity and corresponding increase in leverage ratios during 2023. This suggests a transient period of increased financial risk or balance sheet restructuring before a recovery phase in 2024. The adjusted figures corroborate the reported data trends, indicating consistency in financial reporting adjustments.

The financial data reveals several notable trends in profitability and sales performance over the five-year period. Sales increased steadily year over year, rising from US$47,994 million in 2020 to US$64,168 million in 2024, which represents a consistent upward trajectory in revenue generation.

Net income attributable to the company exhibited considerable volatility. After nearly doubling from 7,067 million in 2020 to 13,049 million in 2021, net income further increased to 14,519 million in 2022. However, a significant decline occurred in 2023, where net income dropped sharply to 365 million. This plunge was followed by a strong recovery in 2024, with net income rising to 17,117 million, the highest value in the examined period.

Reported net profit margin reflected a similar pattern. Starting at 14.72% in 2020, it peaked at 26.79% in 2021, remained relatively high at 24.49% in 2022, and then plummeted to just 0.61% in 2023. This margin rebounded almost to the previous levels, reaching 26.68% in 2024. These fluctuations indicate sharp changes in profitability relative to sales, particularly the dramatic deterioration and subsequent recovery during 2023-2024.

Adjusted net income figures also showed noteworthy variation. The adjusted net income rose significantly from 5,727 million in 2020 to 14,282 million in 2021 before declining to 12,782 million in 2022. In 2023, adjusted net income turned negative, recording a loss of 1,431 million, signaling extraordinary or one-time factors affecting earnings. By 2024, adjusted net income recovered strongly to 16,231 million, exceeding previous highs.

Adjusted net profit margin followed the adjusted net income trend, demonstrating a rise from 11.93% in 2020 to a peak of 29.32% in 2021. It dropped to 21.56% in 2022 and then fell deeply into negative territory at -2.38% in 2023, before sharply recovering to 25.29% in 2024. This pattern underscores the impact of adjustments on profit margins and highlights the exceptional impact in 2023.

Overall, the data indicates strong growth in sales and generally positive profitability margins, albeit interrupted by a significant earnings and margin decline in 2023 followed by a robust recovery in 2024. The volatile profitability in 2023 merits further investigation to identify underlying causes, such as non-recurring charges or extraordinary items affecting net income and adjusted figures during that year.

The financial data reveals significant fluctuations in both profitability and equity measures over the five-year period. Net income attributable to the company shows an overall increasing trend from 7,067 million US dollars in 2020 to 17,117 million in 2024, with a notable sharp dip to 365 million in 2023. This steep decline in 2023 is also reflected in the adjusted net income, which turns negative at -1,431 million in the same year, after previously rising to 12,782 million in 2022.

Total stockholders’ equity exhibits growth from 25,317 million in 2020 to 46,313 million in 2024, although with a decline in 2023 to 37,581 million. The adjusted total equity follows a similar pattern, increasing steadily until 2022 before decreasing in 2023 and then slightly recovering in 2024.

Both reported and adjusted return on equity (ROE) demonstrate volatility. Reported ROE increases from 27.91% in 2020 to a peak of 34.17% in 2021, remains relatively high through 2022 at 31.57%, then drops sharply to 0.97% in 2023 before rebounding to 36.96% in 2024. Adjusted ROE mirrors this pattern but with a more pronounced negative value of -3.78% in 2023, indicating an operational or extraordinary loss during that year, followed by a recovery to 35.55% in 2024.

Overall, the data suggest that the company experienced a major disruption in 2023, adversely affecting profitability and returns on equity. Despite this setback, equity levels and incomes generally improved before and after this period, indicating resilience and a strong recovery trajectory by the end of 2024.

Net Income Attributable to Merck & Co., Inc.
Net income exhibited significant volatility over the five-year period. It increased from $7,067 million in 2020 to a peak of $14,519 million in 2022, followed by a sharp decline to $365 million in 2023, before recovering strongly to $17,117 million in 2024. The sudden drop in 2023 suggests the impact of extraordinary or non-recurring items affecting profitability that year.
Total Assets
Total assets demonstrated a gradual upward trend from $91,588 million in 2020 to $117,106 million in 2024, with minor fluctuations. The asset base increased steadily through 2022, decreased slightly in 2023, and then rebounded in 2024, indicating consistent growth in the company's asset holdings despite the slight dip in the fourth year.
Reported Return on Assets (ROA)
The reported ROA closely reflected the pattern of net income, increasing from 7.72% in 2020 to 13.3% in 2022, dropping sharply to 0.34% in 2023, and then rising to 14.62% in 2024. This indicates the company's efficiency in generating profit from its asset base was significantly impacted in 2023, aligning with the net income decrease.
Adjusted Net Income
Adjusted net income showed a different pattern than reported net income. It rose from $5,727 million in 2020 to a peak of $14,282 million in 2021, then declined to $12,782 million in 2022. In 2023, there was a notable negative value of -$1,431 million, signaling adjusted operational or other adjustments leading to a loss. The figure recovered to $16,231 million in 2024, surpassing previous years, indicating a strong rebound in underlying profitability.
Adjusted Total Assets
The adjusted total assets remained relatively stable, increasing moderately from $90,861 million in 2020 to $114,434 million in 2024. Similar to total assets, adjusted assets dipped slightly in 2023 but recovered in 2024, suggesting consistency in asset valuation adjustments over the years.
Adjusted Return on Assets (ROA)
The adjusted ROA climbed from 6.3% in 2020 to a high of 13.59% in 2021, then decreased to 11.72% in 2022 before turning negative at -1.36% in 2023. In 2024, adjusted ROA rebounded sharply to 14.18%. The negative adjusted ROA in 2023 highlights a period of operational challenges or non-recurring adverse adjustments affecting the company's returns, which were subsequently reversed in 2024.
Overall Analysis
The data reveals strong growth and profitability from 2020 to 2022, interrupted by a significant downturn in 2023 as evidenced by both reported and adjusted figures. This downturn included a substantial decline in net income and a negative adjusted ROA, reflecting either extraordinary losses, restructuring costs, or other adverse impacts. In 2024, the company demonstrated a robust recovery, exceeding previous profitability levels and continuing asset growth. The trends highlight resilience and a capacity for significant rebound following challenging periods.
