Eaton Corp. plc (NYSE:ETN)

The income tax expense exhibited fluctuating behavior over the five-year period. Current income tax expense generally increased, while deferred income tax expense (benefit) demonstrated significant volatility, ultimately shifting from a benefit to an expense. The overall income tax expense followed a similar pattern of fluctuation.

Current Income Tax Expense

Current income tax expense began at US$780 million in 2021, decreased to US$573 million in 2022, and then increased to US$786 million in 2023. A further increase was observed in 2024, reaching US$922 million, before decreasing slightly to US$796 million in 2025. This suggests a correlation with underlying profitability, though further investigation would be needed to confirm this relationship.

Deferred Income Tax Expense (Benefit)

Deferred income tax exhibited a more dynamic pattern. A benefit of US$30 million was recorded in 2021, which widened to a benefit of US$128 million in 2022. The benefit continued to increase in magnitude, becoming a benefit of US$182 million in 2023, and US$154 million in 2024. However, in 2025, this reversed to an expense of US$45 million. This shift could be attributable to changes in temporary differences between book and tax bases of assets and liabilities, or changes in tax rates.

Total Income Tax Expense

Total income tax expense mirrored the combined effect of the current and deferred components. It decreased from US$750 million in 2021 to US$445 million in 2022, then increased to US$604 million in 2023 and US$768 million in 2024. The expense continued to rise in 2025, reaching US$841 million. The increase in 2025 is largely driven by the reversal of the deferred tax benefit to an expense.

The substantial changes in deferred income tax suggest potential alterations in the company’s balance sheet related to deferred tax assets and liabilities. The overall trend in income tax expense indicates a growing tax burden, particularly in the later years of the period, despite fluctuations.

The relationship between the statutory income tax rate and the effective income tax expense rate demonstrates a notable divergence over the observed period. While the statutory rate remained constant at 25.00 percent, the effective income tax expense rate exhibited significant fluctuations.

Effective Income Tax Rate Trend

In 2021, the effective income tax expense rate was 25.90 percent, slightly exceeding the statutory rate. However, a substantial decrease was observed in 2022, with the effective rate falling to 15.30 percent. This decline continued, albeit at a slower pace, reaching 15.80 percent in 2023. A subsequent increase is noted in 2024, with the effective rate rising to 16.80 percent, and further increasing to 17.10 percent in 2025.

The consistent gap between the statutory and effective rates from 2022 onwards suggests the presence of factors influencing the company’s tax obligations beyond the standard corporate tax rate. These factors could include tax credits, deductions, changes in the geographic mix of earnings, or the impact of international tax regulations. The increasing trend in the effective rate from 2022 to 2025 indicates a diminishing impact of these mitigating factors, or a shift in the company’s earnings profile.

Variance from Statutory Rate

The largest variance from the statutory rate occurred in 2022, with a difference of 9.70 percentage points. This suggests a significant impact from items reducing taxable income during that year. The variance narrowed in subsequent years, reaching 7.90 percentage points in 2025, indicating a lessening of these effects.

Further investigation into the components of the effective income tax expense rate is recommended to fully understand the drivers behind these fluctuations and to assess the sustainability of the observed trends.

The composition of deferred tax assets and liabilities exhibits several notable trends over the five-year period. Significant fluctuations are observed in components related to employee benefits, depreciation, and valuation allowances, alongside consistent, though evolving, balances in income tax loss and credit carryforwards.

Employee Benefits

The balance related to employee benefits decreased from US$348 million in 2021 to US$266 million in 2022, before partially recovering to US$328 million in 2023. A further decline to US$295 million in 2024 was followed by a decrease to US$250 million in 2025. This suggests potential changes in benefit plan structures or actuarial assumptions impacting deferred tax implications.

Depreciation and Amortization

Deferred tax assets arising from depreciation and amortization consistently represent a substantial portion of the total. The balance is negative, indicating a future tax benefit. The magnitude decreased from US$-1,087 million in 2021 to US$-791 million in 2024, and remained relatively stable at US$-792 million in 2025. This reduction likely reflects changes in depreciation methods, asset bases, or taxable income.

Other Accruals and Adjustments

The balance for other accruals and adjustments generally increased over the period, rising from US$385 million in 2021 to US$609 million in 2025. This indicates a growing impact from temporary differences related to various accruals and adjustments. A separate line item, “Accruals and other adjustments”, shows a different trend, decreasing from a negative US$-354 million in 2021 to a positive US$67 million in 2025, suggesting a reversal of previously recognized deferred tax liabilities.

Income Tax Loss Carryforwards

Foreign income tax loss carryforwards represent a significant deferred tax asset, fluctuating between US$3,127 million and US$4,151 million. The balance decreased from US$4,151 million in 2022 to US$3,673 million in 2024, then increased slightly to US$3,784 million in 2025. Ireland income tax loss carryforwards remain relatively small and stable, ranging from US$1 million to US$2 million.

Valuation Allowances

A substantial valuation allowance against income tax loss and income tax credit carryforwards is maintained throughout the period, ranging from US$-3,139 million to US$-3,828 million. The valuation allowance decreased from US$-4,184 million in 2022 to US$-3,556 million in 2024, then increased slightly to US$-3,623 million in 2025. This suggests ongoing uncertainty regarding the realization of these deferred tax assets. A separate, smaller valuation allowance for other items decreased from US$-65 million in 2021 to US$-44 million in 2022, and then to US$-50 million in 2023, with no values reported for 2024 and 2025.

Net Deferred Income Taxes

The net deferred income taxes shifted from a liability of US$-167 million in 2021 to a liability of US$-200 million in 2022. A significant change occurred in 2023, with a balance of US$56 million, transitioning to an asset of US$334 million in 2024 and further increasing to US$442 million in 2025. This indicates a net shift from future tax obligations to future tax benefits, likely driven by the combined effect of changes in the deferred tax asset and liability components, particularly the reduction in valuation allowances and the increase in accruals.

The deferred tax asset and liability positions exhibited distinct trends over the five-year period. Deferred tax assets, classified as noncurrent, generally increased, while deferred tax liabilities, also noncurrent, decreased.

Deferred Tax Assets (Noncurrent)

The value of noncurrent deferred tax assets began at 392 US$ millions in 2021. A decrease was observed in 2022, falling to 330 US$ millions. Subsequently, the asset value increased each year, reaching 458 US$ millions in 2023, 609 US$ millions in 2024, and culminating at 707 US$ millions in 2025. This represents a substantial overall increase during the period.

Deferred Tax Liabilities (Noncurrent)

Noncurrent deferred tax liabilities started at 559 US$ millions in 2021. A slight decrease to 530 US$ millions was noted in 2022. The decline accelerated in subsequent years, with values of 402 US$ millions in 2023, 275 US$ millions in 2024, and 265 US$ millions in 2025. This indicates a consistent reduction in deferred tax liabilities over the observed timeframe.

The contrasting movements in deferred tax assets and liabilities suggest potential shifts in the company’s temporary differences, taxable income projections, or applicable tax rates. The increasing deferred tax asset balance could indicate an expectation of future taxable income against which these assets can be realized. Conversely, the decreasing deferred tax liability balance may reflect a reduction in future taxable amounts or a decrease in temporary differences that will result in future tax obligations.

Net Deferred Tax Position

The net deferred tax position (assets less liabilities) moved from a net liability of 167 US$ millions in 2021 to a net liability of 100 US$ millions in 2022. This trend reversed, resulting in a net asset of 56 US$ millions in 2023, 334 US$ millions in 2024, and 442 US$ millions in 2025. This substantial swing indicates a significant improvement in the overall deferred tax position.

The information presents a five-year trend of financial statement items, both as reported and with adjustments made, presumably related to the removal of deferred tax assets or liabilities. A consistent pattern emerges where the adjusted figures are generally lower than the reported figures for total assets, total liabilities, and total shareholders’ equity. This suggests a material impact from deferred tax adjustments across the period.

Total Assets

Reported total assets demonstrate an overall upward trend, increasing from US$34,027 million in 2021 to US$41,251 million in 2025. However, the adjusted total assets show a slightly lower, but similar, growth trajectory, beginning at US$33,635 million in 2021 and reaching US$40,544 million in 2025. The difference between reported and adjusted assets widens slightly over the period, indicating a growing deferred tax impact on asset valuation.

Total Liabilities

Reported total liabilities also exhibit an increasing trend, moving from US$17,576 million in 2021 to US$21,782 million in 2025. The adjusted total liabilities follow a similar pattern, starting at US$17,017 million in 2021 and ending at US$21,517 million in 2025. The gap between reported and adjusted liabilities remains relatively stable throughout the period.

Total Shareholders’ Equity

Reported total shareholders’ equity increased from US$16,413 million in 2021 to US$19,425 million in 2025. The adjusted shareholders’ equity shows a comparable increase, from US$16,580 million to US$18,983 million over the same timeframe. The difference between reported and adjusted equity is relatively consistent, suggesting a steady impact from deferred tax adjustments on equity.

Net Income

Reported net income attributable to Eaton ordinary shareholders shows a consistent increase over the five-year period, rising from US$2,144 million in 2021 to US$4,087 million in 2025. The adjusted net income also demonstrates an upward trend, increasing from US$2,114 million to US$4,132 million. The difference between reported and adjusted net income is small and relatively consistent, indicating that the deferred tax adjustments have a modest, but present, effect on reported earnings.

In summary, the adjustments consistently reduce the reported values of assets, liabilities, equity, and net income. The magnitude of these adjustments appears to be growing over time, particularly concerning total assets. This suggests a potential shift in the company’s tax position or accounting practices related to deferred taxes. The impact on net income is less pronounced, but still present.

The financial metrics demonstrate a general trend of improvement across the observed period, with adjustments for deferred taxes resulting in modestly lower values for most ratios. The differences between reported and adjusted figures suggest that deferred tax assets and liabilities have a notable impact on the company’s reported financial performance. Overall, the adjusted ratios provide a potentially more conservative view of profitability and returns.

Profitability

Reported net profit margin exhibits an increasing trend from 10.92% in 2021 to 15.25% in 2024, with a slight decrease to 14.89% in 2025. The adjusted net profit margin follows a similar pattern, consistently lower than the reported margin, increasing from 10.77% to 15.05% over the same period. This indicates that deferred taxes contribute positively to reported net income. The magnitude of the difference between reported and adjusted margins remains relatively stable throughout the period.

Asset Utilization

Reported total asset turnover shows a steady increase from 0.58 in 2021 to 0.67 in 2025, indicating improving efficiency in asset utilization. The adjusted total asset turnover mirrors this trend, also increasing from 0.58 to 0.68. The difference between reported and adjusted values is minimal, suggesting that deferred taxes have a limited impact on the assessment of how effectively assets are employed to generate sales.

Financial Leverage

Reported financial leverage remains relatively stable between 2.02 and 2.12 over the period, with a slight increase in the later years. The adjusted financial leverage also demonstrates a similar pattern, remaining close to 2.0, and slightly increasing to 2.14 in 2025. The adjustments for deferred taxes result in slightly lower leverage ratios, indicating a marginally more conservative capital structure when these items are excluded.

Return on Equity (ROE)

Reported ROE demonstrates substantial growth, increasing from 13.06% in 2021 to 21.04% in 2025. The adjusted ROE also increases, from 12.75% to 21.77%, but remains consistently below the reported ROE. This difference widens as ROE increases, suggesting that deferred tax items contribute significantly to the reported return on equity.

Return on Assets (ROA)

Reported ROA increases from 6.30% in 2021 to 9.91% in 2025, indicating improved profitability relative to assets. The adjusted ROA follows a similar upward trend, increasing from 6.29% to 10.19%. The difference between reported and adjusted ROA is small, but consistent, indicating a modest positive impact from deferred taxes on the reported return on assets.

In summary, the adjustments for deferred taxes consistently result in lower, though generally proportional, values for profitability and return ratios. The impact on asset turnover and financial leverage is minimal. The increasing trend in most ratios suggests improving financial performance, but the adjustments provide a more conservative perspective on the company’s underlying profitability and returns.

Reported net income attributable to Eaton ordinary shareholders exhibited a consistent upward trend from 2021 through 2025, increasing from US$2,144 million to US$4,087 million. A similar, though slightly less pronounced, increase is observed in adjusted net income attributable to Eaton ordinary shareholders, rising from US$2,114 million in 2021 to US$4,132 million in 2025.

Reported Net Profit Margin

The reported net profit margin demonstrated an increasing trend between 2021 and 2024, progressing from 10.92% to 15.25%. However, this margin experienced a slight decrease in 2025, settling at 14.89%. This suggests a potential stabilization or minor reduction in profitability as a percentage of revenue in the most recent year.

Adjusted Net Profit Margin

The adjusted net profit margin mirrored the trend of the reported net profit margin, showing growth from 10.77% in 2021 to 14.63% in 2024. Like the reported margin, the adjusted net profit margin also increased to 15.05% in 2025, exceeding the reported margin. This indicates that adjustments to net income resulted in a slightly higher profitability percentage compared to the reported figures in the final year.

The difference between reported and adjusted net profit margins remained relatively small across the observed period, fluctuating between approximately 0.15% and 0.42%. This suggests that the adjustments made to net income do not fundamentally alter the overall profitability picture. The consistent growth in both reported and adjusted net profit margins from 2021 to 2024 indicates improving operational efficiency or revenue growth, or a combination of both. The slight leveling off in 2025 warrants further investigation to determine the underlying causes.

The information presents a five-year trend of reported and adjusted total assets, alongside their corresponding turnover ratios. Both reported and adjusted total assets demonstrate a general upward trajectory throughout the period. However, the rate of increase fluctuates, with a more substantial rise observed between 2022 and 2023, followed by a slight decrease in 2024, and then renewed growth through 2025.

Adjusted Total Assets

Adjusted total assets increased from US$33,635 million in 2021 to US$40,544 million in 2025. The largest year-over-year increase occurred between 2022 and 2023, growing by US$3,290 million. A minor decrease of US$60 million was noted between 2023 and 2024, before resuming growth of US$772 million in 2025.

Reported Total Asset Turnover

Reported total asset turnover exhibited a consistent, albeit modest, increase over the five-year period. Starting at 0.58 in 2021, it rose to 0.67 in 2025. The increase from 2023 to 2024 was more pronounced, moving from 0.60 to 0.65, suggesting improved efficiency in asset utilization during that year.

Adjusted Total Asset Turnover

The adjusted total asset turnover ratio mirrors the trend of the reported ratio, also showing a steady increase from 0.58 in 2021 to 0.68 in 2025. Similar to the reported ratio, the largest single-year increase was observed between 2023 and 2024, climbing from 0.61 to 0.66. The adjusted turnover ratio consistently remains slightly higher than the reported turnover ratio throughout the period.

The consistent increase in both reported and adjusted total asset turnover ratios suggests a strengthening ability to generate sales from its asset base. The slight divergence between the reported and adjusted ratios indicates that adjustments to total assets are resulting in a marginally more favorable turnover calculation. The relatively small changes year-over-year suggest a stable, rather than dramatic, improvement in asset utilization efficiency.

An examination of the financial information reveals trends in both reported and adjusted financial leverage over a five-year period. Both total assets and total shareholders’ equity generally increased during the period, though with some fluctuations. The adjusted figures show a slightly different picture than the reported figures, primarily due to differences in the asset and equity calculations.

Total Assets

Reported total assets increased from US$34,027 million in 2021 to US$41,251 million in 2025. There was a slight decrease between 2022 and 2023, followed by further growth in subsequent years. Adjusted total assets followed a similar pattern, beginning at US$33,635 million in 2021 and reaching US$40,544 million in 2025, with a comparable dip between 2022 and 2023.

Total Shareholders’ Equity

Reported total shareholders’ equity exhibited an overall upward trend, increasing from US$16,413 million in 2021 to US$19,425 million in 2025. A decrease was noted between 2023 and 2024. Adjusted total shareholders’ equity mirrored this trend, starting at US$16,580 million in 2021 and ending at US$18,983 million in 2025, also with a decline from 2023 to 2024.

Reported Financial Leverage

Reported financial leverage remained relatively stable between 2021 and 2023, fluctuating around 2.07. An increase was observed in 2024 to 2.08, followed by a further increase to 2.12 in 2025. This indicates a slight increase in the proportion of assets financed by equity over the period.

Adjusted Financial Leverage

Adjusted financial leverage demonstrated a decreasing trend from 2.03 in 2021 to 2.00 in 2023. Similar to the reported leverage, an increase occurred in 2024, reaching 2.08, and continued to rise to 2.14 in 2025. The adjusted leverage consistently remained slightly lower than the reported leverage throughout the observed period. The increases in both reported and adjusted financial leverage in the later years suggest a growing reliance on equity financing relative to assets.

The consistency between the trends in reported and adjusted financial leverage suggests that the adjustments made do not fundamentally alter the overall picture of the company’s financial structure. The slight increases in leverage in the final two years of the period warrant further investigation to determine the underlying drivers and potential implications.

Over the five-year period ending December 31, 2025, both reported and adjusted net income attributable to Eaton ordinary shareholders demonstrate a consistent upward trajectory. Shareholders’ equity, both reported and adjusted, generally increased, although a slight decrease in reported shareholders’ equity is observed in 2024. Consequently, both reported and adjusted return on equity (ROE) exhibit an increasing trend throughout the period.

Net Income Trends

Reported net income increased from US$2,144 million in 2021 to US$4,087 million in 2025, representing a substantial overall increase. Adjusted net income followed a similar pattern, rising from US$2,114 million to US$4,132 million over the same timeframe. The difference between reported and adjusted net income remains relatively consistent across the years, suggesting similar adjustments are being made annually.

Shareholders’ Equity Trends

Reported total shareholders’ equity grew from US$16,413 million in 2021 to US$19,425 million in 2025. However, a decrease to US$18,488 million is noted in 2024 before recovering in the subsequent year. Adjusted total shareholders’ equity mirrors this trend, increasing from US$16,580 million to US$18,983 million, with a similar dip in 2024 to US$18,154 million. The adjusted equity consistently exceeds the reported equity throughout the period.

Return on Equity (ROE) Analysis

Reported ROE increased steadily from 13.06% in 2021 to 21.04% in 2025. Adjusted ROE also showed consistent growth, moving from 12.75% to 21.77% over the same period. The adjusted ROE consistently exceeds the reported ROE, indicating that the adjustments to net income and/or equity positively impact the return metric. The rate of increase in ROE appears to accelerate between 2022 and 2024 for both reported and adjusted figures.

The convergence of increasing net income and generally increasing shareholders’ equity results in the observed upward trend in both reported and adjusted ROE. The slight decrease in shareholders’ equity in 2024 did not prevent continued growth in ROE, suggesting strong net income generation was sufficient to offset the equity reduction.

Reported and adjusted net income attributable to Eaton ordinary shareholders exhibited a consistent upward trend from 2021 through 2025. Reported total assets increased over the period, with a slight decrease observed between 2023 and 2024 before resuming growth. Adjusted total assets mirrored this pattern. Consequently, both reported and adjusted return on assets (ROA) demonstrated an overall positive trajectory.

Reported Net Income & ROA

Reported net income increased from US$2,144 million in 2021 to US$4,087 million in 2025, representing a substantial increase over the five-year period. Correspondingly, reported ROA rose from 6.30% in 2021 to 9.91% in 2025. The rate of increase in reported ROA slowed slightly between 2024 and 2025.

Adjusted Net Income & ROA

Adjusted net income followed a similar pattern to reported net income, growing from US$2,114 million in 2021 to US$4,132 million in 2025. Adjusted ROA increased from 6.29% in 2021 to 10.19% in 2025. The adjusted ROA consistently exceeded the reported ROA throughout the analyzed period, although the difference between the two narrowed in 2025.

Asset Trends

Reported total assets increased from US$34,027 million in 2021 to US$41,251 million in 2025. A minor decrease was noted between 2023 (US$38,432 million) and 2024 (US$38,381 million). Adjusted total assets exhibited a similar trend, increasing from US$33,635 million in 2021 to US$40,544 million in 2025, with a comparable decrease between 2023 and 2024.

ROA Comparison

The difference between reported and adjusted ROA remained relatively small across the period, fluctuating between approximately 0.01% and 0.28%. This suggests that the adjustments made to net income and total assets had a limited, though measurable, impact on the calculated ROA. The convergence of reported and adjusted ROA in 2025 warrants further investigation into the nature of the adjustments.

Overall, the financial performance, as indicated by ROA, improved consistently over the five-year period. The slight dip in asset values between 2023 and 2024 did not materially impact the positive ROA trend.
