International Business Machines Corp. (NYSE:IBM)

The income tax expense and benefit exhibited significant fluctuations over the five-year period. Current tax expense generally increased from 2021 to 2022, then remained relatively stable before decreasing substantially in 2025. Deferred tax expense, conversely, showed a marked increase in absolute value from 2021 to 2022, followed by a decrease in 2023, and then another increase in 2024 before decreasing again in 2025. The provision for (benefit from) income taxes related to continuing operations demonstrated the most volatility, swinging from a benefit in 2022 to a substantial provision in 2023, then back to a benefit in 2024 and 2025.

Current Tax Expense

Current tax expense increased from US$1,877 million in 2021 to US$2,251 million in 2022, representing a growth of approximately 20%. It remained relatively consistent at US$2,281 million in 2023 and US$2,118 million in 2024 before declining significantly to US$715 million in 2025. This final decrease suggests a substantial reduction in taxable income or changes in applicable tax rates.

Deferred Tax Expense

Deferred tax expense moved from a benefit of US$1,753 million in 2021 to a larger benefit of US$2,877 million in 2022. This was followed by a reduction in the benefit to US$1,105 million in 2023, and then a shift to an expense of US$2,336 million in 2024. The deferred tax expense decreased again in 2025 to US$957 million. These fluctuations likely correlate with changes in temporary differences between the book and tax bases of assets and liabilities, as well as changes in tax laws or rates impacting deferred tax assets and liabilities.

Continuing Operations Provision

The provision for (benefit from) income taxes from continuing operations experienced considerable variation. A benefit of US$626 million was recorded in 2022, indicating that tax benefits exceeded current tax liabilities. This was followed by a provision of US$1,176 million in 2023, suggesting a significant tax liability. A benefit reappeared in 2024 (US$218 million) and continued in 2025 (US$242 million), though at a lower magnitude than in 2022. The volatility in this line item suggests significant changes in the company’s taxable income, tax planning strategies, or the utilization of tax loss carryforwards.

Overall, the income tax figures demonstrate a complex interplay of current and deferred tax effects, alongside substantial year-over-year changes in the provision for income taxes from continuing operations. Further investigation into the underlying drivers of these fluctuations, such as changes in profitability, tax rates, and tax planning activities, would be necessary for a more comprehensive understanding.

The effective income tax rate exhibits significant volatility over the observed period. While the U.S. federal statutory tax rate remained constant at 21.00% throughout the years presented, the effective tax rate fluctuated considerably, indicating substantial differences between reported tax expense and what would be expected based on pre-tax income.

Effective Tax Rate Trend

In 2021, the effective tax rate was 3.00%, substantially below the statutory rate. This suggests the presence of tax benefits, such as tax credits, deductions, or income earned in lower-tax jurisdictions. A dramatic shift occurred in 2022, with the effective tax rate becoming negative at -54.00%. This negative rate implies that the company benefited from tax events that reduced its tax liability below zero, potentially including the reversal of previously established tax liabilities or significant tax benefits related to specific transactions. The rate then moved to a positive 14.00% in 2023, representing a substantial increase from the prior year, but still remaining below the statutory rate. Further volatility is observed in 2024 and 2025, with the effective tax rate declining to -4.00% and -2.00% respectively. These subsequent negative rates suggest continued, though diminishing, benefits from tax-reducing events.

The considerable divergence between the effective tax rate and the statutory tax rate across the period warrants further investigation. The negative effective tax rates in 2022, 2024, and 2025 are particularly noteworthy and likely driven by specific, non-recurring items or strategic tax planning initiatives. Understanding the underlying drivers of these fluctuations is crucial for assessing the company’s long-term tax position and potential future tax obligations.

Potential Drivers of Volatility

Fluctuations in the effective tax rate could stem from several factors. These include changes in the geographic mix of earnings, the utilization of net operating losses, the impact of research and development tax credits, and adjustments to deferred tax assets and liabilities. The magnitude of the negative rates suggests that the company may be realizing benefits from significant tax planning strategies or one-time events. A detailed review of the company’s tax footnotes would be necessary to pinpoint the specific causes of these variations.

The composition of deferred tax assets and liabilities exhibits notable shifts over the five-year period. Overall, net deferred tax assets increased consistently, indicating a growing potential for future tax benefits. This growth is driven by changes in the underlying components of both deferred tax assets and deferred tax liabilities.

Gross Deferred Tax Assets

Gross deferred tax assets generally increased from US$15,652 million in 2021 to US$18,422 million in 2025. The most significant contributors to these assets are tax losses/credits, intangible assets, and capitalized R&D. Tax losses/credits demonstrate a consistent upward trend, rising from US$2,602 million to US$3,923 million. Capitalized R&D also shows substantial growth, increasing from US$2,161 million to US$4,426 million, suggesting increased investment in research and development activities. Retirement benefits contribute a significant amount, though with a decreasing trend over the period. A new component, hedging, appears in 2025 at US$270 million.

Valuation Allowance

The valuation allowance against deferred tax assets experienced fluctuations. While initially decreasing from US$883 million in 2021 to US$765 million in 2023, it increased to US$1,223 million in 2024 before decreasing slightly to US$1,143 million in 2025. This suggests periods of increased uncertainty regarding the realizability of certain deferred tax assets, followed by some renewed confidence. The increase in 2024 warrants further investigation.

Net Deferred Tax Assets

Net deferred tax assets increased steadily from US$14,769 million in 2021 to US$17,279 million in 2025, reflecting the combined effect of growing gross deferred tax assets and fluctuating valuation allowances. This indicates a strengthening position in terms of future tax benefits.

Gross Deferred Tax Liabilities

Gross deferred tax liabilities decreased consistently from US$11,356 million in 2021 to US$9,450 million in 2025. The primary drivers of these liabilities are goodwill and intangible assets, GILTI deferred taxes, and leases and right-of-use assets. Goodwill and intangible assets represent the largest portion of the liabilities, with a gradual decline over the period. GILTI deferred taxes also show a consistent decrease, while liabilities related to leases and right-of-use assets also decreased. Retirement benefits contribute a substantial amount, with a relatively stable decline.

Specific Liability Components

The reduction in GILTI deferred taxes from US$3,257 million in 2021 to US$1,606 million in 2025 may be attributable to changes in international tax regulations or the company’s global income structure. The decrease in liabilities related to leases and right-of-use assets likely reflects the amortization of these assets or changes in lease agreements. The consistent decline in retirement benefit liabilities suggests a reduction in future obligations or changes in actuarial assumptions.

Net Deferred Tax Position

The net deferred tax position, calculated as net deferred tax assets less deferred tax liabilities, increased significantly from US$3,413 million in 2021 to US$7,829 million in 2025. This substantial increase suggests a growing ability to utilize future tax benefits, potentially improving future cash flows. The trend indicates a shift from a net liability position to a stronger net asset position.

In summary, the data reveals a strengthening net deferred tax asset position, driven by growth in deferred tax assets related to tax losses, capitalized R&D, and intangible assets, coupled with a consistent decrease in deferred tax liabilities. The fluctuations in the valuation allowance warrant continued monitoring to assess the realizability of deferred tax assets.

The deferred tax asset balance exhibited a fluctuating pattern over the five-year period. Beginning at US$7,370 million in 2021, the balance decreased to US$6,256 million in 2022. A modest increase was then observed in 2023, reaching US$6,656 million, followed by further growth to US$6,978 million in 2024. The most significant increase occurred between 2024 and 2025, with the deferred tax asset balance rising to US$8,610 million.

In contrast, deferred tax liabilities demonstrated a consistent downward trend throughout the period. Starting at US$3,956 million in 2021, the balance declined to US$2,292 million in 2022. This downward trajectory continued in subsequent years, with values of US$1,146 million, US$815 million, and US$781 million reported for 2023, 2024, and 2025, respectively.

Overall Trend

The net deferred tax position, calculated as deferred tax assets less deferred tax liabilities, has increased substantially over the period. This suggests a growing potential for future tax benefits. The decrease in deferred tax liabilities is more pronounced than the increase in deferred tax assets, contributing significantly to this net increase.

Asset Fluctuation

The initial decrease in deferred tax assets in 2022 could be attributed to utilization of existing deferred tax assets, changes in temporary differences, or adjustments to valuation allowances. The subsequent increases suggest the generation of new temporary differences or a reduction in valuation allowances.

Liability Reduction

The consistent reduction in deferred tax liabilities indicates a decrease in future taxable amounts arising from temporary differences. This could be due to the reversal of taxable temporary differences, changes in tax laws, or the recognition of tax benefits.

The significant growth in deferred tax assets in 2025, coupled with the continued decline in deferred tax liabilities, warrants further investigation to understand the underlying drivers and potential impact on future tax expense.

The financial information reveals a consistent adjustment downward across all balance sheet and income statement items when removing deferred tax assets and liabilities. This suggests a significant impact from deferred taxes on the reported financial position and performance of the entity.

Total Assets

Reported total assets decreased from US$132,001 million in 2021 to US$127,243 million in 2022, before increasing to US$135,241 million in 2023, US$137,175 million in 2024, and reaching US$151,880 million in 2025. The adjusted total assets follow a similar pattern, but at lower values, ranging from US$124,631 million in 2021 to US$143,270 million in 2025. The difference between reported and adjusted assets remains relatively stable in absolute terms, indicating a consistent deferred tax impact.

Total Liabilities

Reported total liabilities decreased from US$113,005 million in 2021 to US$105,222 million in 2022, then increased to US$112,628 million in 2023, US$109,783 million in 2024, and US$119,139 million in 2025. Adjusted total liabilities exhibit the same trend, but at lower levels, ranging from US$109,049 million in 2021 to US$118,358 million in 2025. The consistent difference between reported and adjusted liabilities suggests a substantial deferred tax liability component.

Total Stockholders’ Equity

Reported total stockholders’ equity increased from US$18,901 million in 2021 to US$21,944 million in 2022, US$22,533 million in 2023, US$27,307 million in 2024, and US$32,648 million in 2025. Adjusted stockholders’ equity also increased, but to a lesser extent, ranging from US$15,488 million in 2021 to US$24,819 million in 2025. The reduction in equity upon adjustment is consistent across all years, indicating a significant deferred tax asset impacting reported equity.

Net Income

Reported net income attributable to the entity fluctuated over the period, starting at US$5,743 million in 2021, decreasing to US$1,639 million in 2022, increasing to US$7,502 million in 2023, US$6,023 million in 2024, and reaching US$10,593 million in 2025. Adjusted net income shows a different pattern, with a decrease to a loss of US$-1,238 million in 2022, followed by increases to US$6,397 million in 2023, US$3,687 million in 2024, and US$9,636 million in 2025. The adjustment significantly lowers net income in 2022 and moderately reduces it in other years, suggesting a substantial impact from deferred tax expense or benefit reversals.

The consistent adjustments to all reported figures indicate that deferred taxes play a crucial role in the entity’s financial reporting. The magnitude of these adjustments warrants further investigation into the nature and composition of the deferred tax assets and liabilities.

The financial performance metrics exhibit notable differences between reported and adjusted values following the removal of deferred tax impacts. Generally, the adjusted ratios demonstrate a more conservative view of profitability and returns, while asset utilization appears modestly improved. A review of individual ratios reveals specific trends and patterns.

Profitability

Reported net profit margin experienced volatility, increasing from 2.71% in 2022 to 15.69% in 2025. The adjusted net profit margin, however, shows a more subdued pattern. It began at 6.96% in 2021, dipped into negative territory at -2.05% in 2022, and then rose to 14.27% in 2025. The divergence between reported and adjusted margins suggests that deferred taxes significantly inflate reported earnings, particularly in certain years. The adjusted figures present a more consistent, though lower, profitability trend.

Asset Utilization

Reported total asset turnover remained relatively stable between 0.43 and 0.48 over the period, with a slight decrease to 0.44 in 2025. The adjusted total asset turnover shows a similar trend, but consistently registers slightly higher values, indicating improved efficiency in utilizing assets when deferred tax effects are excluded. The difference is small, but persistent.

Financial Leverage

Reported financial leverage decreased from 6.98 in 2021 to 4.65 in 2025, indicating a reduction in the company’s reliance on debt financing. Conversely, the adjusted financial leverage consistently exceeds the reported leverage, starting at 8.05 in 2021 and declining to 5.77 in 2025. This suggests that deferred tax liabilities are masking a higher degree of financial risk than is apparent in the reported figures.

Returns on Equity (ROE)

Reported ROE fluctuated considerably, ranging from 7.47% to 33.29%. The adjusted ROE demonstrates a similar pattern of volatility, but with lower overall values. Notably, the adjusted ROE was negative in 2022 (-6.89%), while the reported ROE remained positive. The adjusted ROE reached its highest point in 2025 at 38.83%, exceeding the reported ROE of 32.45%. The substantial difference highlights the impact of deferred taxes on equity returns.

Returns on Assets (ROA)

Reported ROA increased from 1.29% in 2022 to 6.97% in 2025, reflecting improved profitability relative to asset base. The adjusted ROA follows a similar upward trend, but remains lower than the reported ROA throughout the period. Like the ROE, the adjusted ROA was negative in 2022 (-1.02%), indicating a loss when deferred tax effects are removed. The adjusted ROA reached 6.73% in 2025, approaching the reported value.

In summary, removing deferred tax impacts results in a more conservative assessment of financial performance. While reported figures suggest strong profitability and returns, the adjusted ratios reveal a more moderate and, in some instances, negative performance, particularly in 2022. The adjusted ratios also indicate a higher level of financial leverage than is reflected in the reported figures. These differences should be considered when evaluating the company’s overall financial health and future prospects.

The period under review demonstrates considerable fluctuation in both reported and adjusted net income attributable to IBM, which consequently impacts associated profit margins. A notable divergence exists between the reported and adjusted figures, suggesting the presence of significant non-recurring items impacting reported profitability.

Reported Net Profit Margin

Reported net profit margin exhibited volatility throughout the period. Starting at 10.01% in 2021, it decreased substantially to 2.71% in 2022 before recovering to 12.13% in 2023. A slight decline to 9.60% occurred in 2024, followed by a significant increase to 15.69% in 2025. This pattern indicates sensitivity to underlying net income changes.

Adjusted Net Profit Margin

The adjusted net profit margin presents a more dramatic fluctuation. In 2021, it stood at 6.96%, then decreased to a negative value of -2.05% in 2022. A strong recovery was observed in 2023, reaching 10.34%, but this was followed by a decrease to 5.88% in 2024. The adjusted net profit margin concluded the period with a substantial increase to 14.27% in 2025. The negative value in 2022 highlights a period where adjustments significantly reduced profitability below the reported level.

The difference between the reported and adjusted net profit margins widens and narrows across the years, indicating varying degrees of impact from the adjustments made. The substantial increase in both reported and adjusted net profit margins in 2025 suggests a period of improved underlying profitability, or potentially the benefit of favorable adjustments. The negative adjusted net profit margin in 2022 warrants further investigation to understand the nature and magnitude of the adjustments made during that year.

Trend Comparison

Both reported and adjusted net profit margins generally trended upwards from 2022 to 2025, although the adjusted margin experienced a more pronounced recovery from its negative value. The consistent gap between the two margins suggests that non-recurring items or specific accounting adjustments regularly influence the reported financial performance.

Overall, the financial performance, as reflected in these margins, is characterized by instability, particularly in the adjusted figures. The significant swings necessitate a deeper understanding of the factors driving these changes to assess the sustainability of profitability.

An examination of the provided financial information reveals trends in both total asset figures and associated turnover ratios over a five-year period. Reported total assets experienced a decrease between 2021 and 2022, followed by increases in subsequent years, culminating in a notable rise between 2024 and 2025. Adjusted total assets mirrored this pattern, exhibiting a similar initial decline and subsequent growth. The adjusted total asset turnover ratio demonstrates a relatively stable performance, fluctuating within a narrow range throughout the observed timeframe.

Reported Total Assets

Reported total assets decreased from US$132,001 million in 2021 to US$127,243 million in 2022, representing a decline of approximately 3.6%. A subsequent recovery occurred, with assets increasing to US$135,241 million in 2023 and further to US$137,175 million in 2024. The most significant increase was observed between 2024 and 2025, with reported total assets reaching US$151,880 million, a growth of approximately 10.8%.

Adjusted Total Assets

Adjusted total assets followed a similar trajectory to reported total assets. A decrease from US$124,631 million in 2021 to US$120,987 million in 2022 was observed, followed by increases to US$128,585 million in 2023 and US$130,197 million in 2024. The largest increase occurred between 2024 and 2025, reaching US$143,270 million, representing a growth of approximately 10.0%.

Reported Total Asset Turnover

The reported total asset turnover ratio exhibited modest fluctuations. It began at 0.43 in 2021, increased to 0.48 in 2022, then decreased slightly to 0.46 in both 2023 and 2024. A minor decline to 0.44 was noted in 2025. Overall, the ratio remained relatively consistent, indicating a stable level of revenue generation relative to reported assets.

Adjusted Total Asset Turnover

The adjusted total asset turnover ratio demonstrated a similar pattern of stability. Starting at 0.46 in 2021, it rose to 0.50 in 2022, then decreased to 0.48 in both 2023 and 2024. A slight decrease to 0.47 was observed in 2025. The adjusted turnover ratio consistently remained slightly higher than the reported turnover ratio across all periods, suggesting that the adjustments to total assets may provide a more accurate representation of asset utilization.

The convergence of trends in both asset measures and the relatively stable turnover ratios suggest a consistent operational performance despite changes in the overall asset base. The increases in both reported and adjusted total assets in the later years, coupled with maintained turnover ratios, indicate potential growth in revenue without a corresponding decrease in asset efficiency.

An examination of the financial information reveals trends in both reported and adjusted asset and equity figures, impacting calculated financial leverage ratios over the five-year period. Reported total assets experienced a decrease between 2021 and 2022, followed by increases in subsequent years, culminating in a substantial rise between 2024 and 2025. Adjusted total assets mirrored this pattern, though the magnitude of change differed. Similarly, reported total stockholders’ equity consistently increased throughout the period, with the most significant growth occurring between 2023 and 2025. Adjusted total stockholders’ equity also increased, but exhibited a decrease between 2022 and 2023.

Reported Financial Leverage

Reported financial leverage decreased steadily from 6.98 in 2021 to 4.65 in 2025. This indicates a diminishing proportion of assets financed by equity, or conversely, a decreasing reliance on equity financing relative to assets. The rate of decline slowed from 2023 to 2024 and 2024 to 2025.

Adjusted Financial Leverage

Adjusted financial leverage began at 8.05 in 2021, decreased to 6.73 in 2022, increased to 7.55 in 2023, and then decreased to 5.77 in 2025. The adjusted leverage ratio consistently remained higher than the reported leverage ratio throughout the period. The fluctuations suggest a more pronounced impact from the adjustments made to total assets and equity when assessing financial leverage. The largest single-year decrease occurred between 2023 and 2025.

Asset and Equity Adjustments

The difference between reported and adjusted figures for both total assets and stockholders’ equity varied annually. The adjustments to total assets were generally smaller in magnitude than those to stockholders’ equity. The adjustments suggest the presence of items impacting the reported values that are excluded in the adjusted calculations, potentially related to specific accounting treatments or non-operating assets. The adjustments to equity were more substantial, indicating a potentially significant impact from these excluded items on the overall equity position.

In summary, while both reported and adjusted financial leverage ratios demonstrate a general trend towards lower leverage over the period, the adjusted ratios consistently indicate a higher level of financial risk. The adjustments to both assets and equity suggest the presence of factors influencing the reported financial position that are not captured in the adjusted figures, warranting further investigation into the nature of these adjustments.

The period between 2021 and 2025 demonstrates considerable fluctuation in both reported and adjusted net income, impacting return on equity calculations. Reported net income experienced a significant decrease from 2021 to 2022, followed by substantial increases in subsequent years, peaking in 2025. Adjusted net income exhibited even more volatility, including a net loss in 2022, before recovering and ultimately surpassing reported net income by 2025. Stockholders’ equity, both reported and adjusted, generally increased over the five-year period, though adjusted equity experienced a decline from 2022 to 2023.

Reported Return on Equity (ROE)

Reported ROE mirrored the trends in reported net income. It decreased substantially from 30.38% in 2021 to 7.47% in 2022, then increased to 33.29% in 2023, decreased to 22.06% in 2024, and rose again to 32.45% in 2025. This indicates a strong correlation between reported profitability and the reported ROE.

Adjusted Return on Equity (ROE)

Adjusted ROE displayed greater volatility than its reported counterpart. A significant decline was observed in 2022, resulting in a negative return of -6.89%. The adjusted ROE then rose sharply to 37.58% in 2023, decreased to 17.44% in 2024, and continued to increase, reaching 38.83% in 2025. The negative adjusted ROE in 2022 suggests the impact of specific adjustments significantly reduced profitability in that year.

Relationship between Reported and Adjusted ROE

The difference between reported and adjusted ROE varied across the period. In 2021 and 2025, the adjusted ROE was lower than the reported ROE, suggesting that adjustments reduced the calculated return. However, in 2023, the adjusted ROE was notably higher, indicating that the adjustments increased the calculated return. The substantial difference in 2022, with a negative adjusted ROE compared to a positive reported ROE, highlights the significant impact of the adjustments made to net income and equity.

The increasing trend in stockholders’ equity, alongside the fluctuating net income figures, suggests a complex interplay of profitability and capital structure. The divergence between reported and adjusted ROE indicates that non-recurring items or accounting adjustments play a substantial role in the company’s overall financial performance as measured by return on equity.

The period between 2021 and 2025 demonstrates fluctuating performance in reported and adjusted net income, impacting return on assets calculations. Reported net income exhibits volatility, initially decreasing significantly from 2021 to 2022 before recovering and increasing through 2025. Adjusted net income mirrors this pattern, with a substantial decline in 2022 resulting in a negative value, followed by a recovery and growth trend. Total assets, both reported and adjusted, generally increased over the five-year period, though with some year-over-year fluctuations.

Reported Return on Assets (ROA)

Reported ROA decreased from 4.35% in 2021 to 1.29% in 2022, coinciding with the decline in reported net income. A subsequent increase to 5.55% in 2023 reflects the recovery in net income. The ROA remained relatively stable at 4.39% in 2024 before increasing to 6.97% in 2025, indicating improved profitability relative to total assets. The overall trend suggests a strengthening of asset utilization in generating reported profits.

Adjusted Return on Assets (ROA)

Adjusted ROA experienced a more pronounced fluctuation. It decreased from 3.20% in 2021 to -1.02% in 2022, driven by the negative adjusted net income. The adjusted ROA recovered to 4.97% in 2023 and 2.83% in 2024, but remained below the 2021 level. A significant increase to 6.73% in 2025 suggests improved profitability based on the adjusted figures. The negative value in 2022 highlights the impact of adjustments on profitability assessment.

The divergence between reported and adjusted ROA values indicates that adjustments to net income and total assets have a material effect on the assessment of the company’s profitability. The consistent increase in both reported and adjusted ROA from 2023 to 2025 suggests a positive trend in asset utilization and profitability, although the adjusted figures consistently lag behind the reported figures. The growth in total assets, alongside increasing net income, contributes to the overall improvement in ROA during the latter part of the analyzed period.
