ONEOK Inc. (NYSE:OKE)

The provision for income taxes exhibited significant volatility between 2018 and 2022, characterized by a notable contraction in 2020 followed by a strong upward trajectory. Total tax obligations reached a five-year peak in 2022, totaling 527,424 thousand US dollars.

Current Tax Expense Trends

Current tax obligations remained relatively low and unstable during the early part of the period, including a tax benefit of 315 thousand US dollars recorded in 2019. However, a sharp escalation is observed starting in 2021, with the expense rising from 2,777 thousand US dollars in 2020 to 64,005 thousand US dollars by 2022. This represents a substantial increase in the immediate cash tax burden.

Deferred Tax Expense Analysis

Deferred tax expenses served as the primary driver of the total tax provision throughout the analyzed period. After remaining stable around 361,000 to 372,000 thousand US dollars in 2018 and 2019, a significant decline occurred in 2020, where expenses dropped to 186,730 thousand US dollars. A rapid recovery followed in 2021, peaking at 472,057 thousand US dollars before stabilizing slightly at 463,419 thousand US dollars in 2022.

Aggregate Provision Performance

The overall provision for income taxes mirrored the fluctuations of the deferred tax component, experiencing a sharp dip of approximately 49% between 2019 and 2020. From 2021 onward, a consistent upward trend emerged, driven by the simultaneous recovery of deferred tax expenses and the exponential growth of current tax expenses, resulting in the highest total provision of the five-year period in 2022.

The analysis of income tax rates from 2018 through 2022 reveals a consistent variance between the federal statutory baseline and the actual tax burden realized by the entity. The effective income tax rate (EITR) remained consistently higher than the federal statutory rate throughout the entire five-year period.

Federal Statutory Income Tax Rate

The federal statutory rate remained unchanged at 21.00% from 2018 to 2022, establishing a constant benchmark for the analysis of tax efficiency.

Effective Income Tax Rate (EITR) Volatility

The EITR exhibited moderate fluctuations, beginning at 23.96% in 2018 and reaching a period low of 22.56% in 2019. A subsequent upward trend occurred over the following two years, peaking at 24.42% in 2021, before moderating to 23.44% in 2022.

Analysis of the Statutory-Effective Gap

The EITR consistently exceeded the statutory rate by a margin ranging from 1.56 to 3.42 percentage points. This persistent premium indicates that additional tax liabilities, likely originating from state and local taxes or non-deductible expenses, consistently offset any available federal tax credits or incentives.

The company's deferred tax position experienced a significant transition between 2018 and 2022, moving from a relatively moderate liability to a substantial net deferred tax liability. While deferred tax assets saw a period of rapid growth peaking in 2020, this was eclipsed by a consistent and accelerated increase in deferred tax liabilities over the same five-year horizon.

Deferred Tax Assets (DTAs)

Gross deferred tax assets increased from $655.4 million in 2018 to a peak of $1.98 billion in 2020, before trending downward to $1.43 billion by 2022. The primary driver of this volatility was the Federal net operating loss, which surged from $420.3 million in 2018 to a peak of $1.47 billion in 2020. Derivative instruments also contributed to the 2020 peak, reaching $134.5 million before declining sharply to $18.8 million by 2022. Net deferred tax assets, after accounting for valuation allowances, followed this pattern, peaking at $1.85 billion in 2020 and ending the period at $1.36 billion.

Deferred Tax Liabilities (DTLs)

Deferred tax liabilities exhibited a consistent and steep upward trajectory, growing from $801.3 million in 2018 to $3.10 billion in 2022. This growth was almost entirely driven by investments in partnerships, which increased from $728.2 million in 2018 to $3.00 billion in 2022. Other components, such as the excess of tax over book depreciation, remained relatively stable, moving from $73.1 million in 2018 to $94.8 million in 2022, indicating that the liability growth is tied to investment activity rather than depreciation differentials.

Net Deferred Tax Position

The net deferred tax liability expanded substantially over the analyzed period, increasing from $219.7 million in 2018 to $1.74 billion in 2022. The data indicates that the accumulation of liabilities related to partnership investments outpaced the growth and utilization of net operating losses and other deferred tax assets. The most significant divergence occurred between 2020 and 2022, where net deferred tax assets declined while liabilities continued to climb, leading to a rapid widening of the net liability position.

Deferred tax liabilities exhibited a consistent and substantial increase over the five-year period ending December 31, 2022. The trajectory indicates a continuous expansion of the temporary differences between the reporting of taxable income and accounting income.

Growth Magnitude

The balance of deferred tax liabilities grew from 219,731 thousand US dollars in 2018 to 1,738,525 thousand US dollars by 2022, representing an overall increase of approximately 691% over the observed period.

Year-over-Year Progression

A sharp increase is observed between 2018 and 2019, where liabilities more than doubled. This upward trend continued through 2020 and 2021, with a further significant jump in 2022, adding over 571 million US dollars in a single fiscal year.

Financial Interpretation

The persistent rise in deferred tax liabilities suggests an increasing accumulation of future tax obligations. Such a pattern is typically indicative of expanded capital investments and the subsequent use of accelerated depreciation for tax purposes, which creates a widening gap between tax-deductible expenses and book expenses.

The removal of deferred tax liabilities results in a systemic adjustment that lowers the total liability profile while concurrently enhancing shareholders' equity. This adjustment provides a normalized view of the company's solvency and net worth by eliminating the impact of future tax obligations from the balance sheet calculations.

Liability Profile Adjustments

A widening divergence is observed between reported and adjusted total liabilities from 2018 through 2022. While reported liabilities increased from approximately $11.65 billion to $17.89 billion, the adjusted figures grew at a slower pace, ending at $16.15 billion in 2022. The variance between reported and adjusted liabilities expanded from $219.7 million in 2018 to $1.74 billion in 2022, indicating a substantial increase in the amount of deferred taxes removed from the adjusted liability total.

Equity Position Enhancement

The adjustment leads to a proportional increase in shareholders' equity. Adjusted total equity rose from $6.80 billion in 2018 to $8.23 billion in 2022, whereas reported equity remained relatively stagnant between 2018 and 2021 before rising in 2022. The gap between reported and adjusted equity mirrors the liability trend, expanding from $219.7 million in 2018 to $1.74 billion in 2022, which suggests that the deferred tax removal significantly strengthens the perceived capital base of the company.

Net Income Variance

Adjusted net income attributable to shareholders is consistently higher than reported net income across the entire five-year period. The most pronounced positive variances occurred in 2021 and 2022, with adjusted net income reaching $1.97 billion and $2.19 billion, respectively. This pattern indicates that the removal of tax-related adjustments consistently presents a more favorable earnings profile than the statutory reported figures, effectively smoothing the impact of tax liabilities on bottom-line profitability.

The removal of deferred taxes consistently results in an improvement across all analyzed profitability and efficiency metrics, while simultaneously reducing the calculated financial leverage from 2018 to 2022. This indicates that deferred tax accounting creates a persistent gap between reported figures and the adjusted underlying financial performance.

Profitability Margins

The adjusted net profit margin remains consistently higher than the reported margin throughout the five-year period. A peak in profitability occurred in 2019, where the adjusted margin reached 16.25% compared to the reported 12.58%. While both metrics experienced a significant contraction in 2020, the adjusted margin mitigated the perceived impact, staying at 9.36% while the reported margin dropped to 7.17%.

Financial Leverage

A divergence is observed between reported and adjusted leverage. Reported financial leverage showed an upward trend from 2.77 in 2018 to a peak of 3.93 in 2021. In contrast, the adjusted leverage remained lower in every period and exhibited a downward trajectory after 2020, decreasing from 3.44 to 2.96 by 2022. This suggests that deferred tax liabilities contribute significantly to the reported leverage ratios.

Return on Equity (ROE)

Adjusted ROE consistently exceeds reported ROE, particularly between 2018 and 2021. The most substantial variance occurred in 2018, with a difference of 4.75 percentage points. However, by 2022, the reported ROE (26.52%) and adjusted ROE (26.55%) converged, indicating that the impact of deferred taxes on equity returns diminished toward the end of the period.

Return on Assets (ROA)

The adjusted ROA is higher than the reported ROA across all years, mirroring the trend seen in net profit margins. Both metrics bottomed out in 2020 at 2.66% (reported) and 3.46% (adjusted) before recovering. By 2022, the adjusted ROA reached its period high of 8.97%, while the reported ROA stood at 7.06%, maintaining a consistent premium of approximately 1.91 percentage points.

The financial performance from 2018 to 2022 is characterized by a significant contraction in 2020 followed by a robust recovery in absolute earnings, although profit margins exhibit higher volatility and a subsequent decline in the final year of the period.

Net Income Trends

Reported net income increased from 1,151,703 thousand US$ in 2018 to 1,722,221 thousand US$ in 2022. A sharp decline occurred in 2020, with income falling to 612,809 thousand US$, before rebounding strongly in 2021 and 2022. Adjusted net income follows a similar trajectory but maintains consistently higher values than reported figures, peaking at 2,185,640 thousand US$ in 2022.

Net Profit Margin Analysis

The adjusted net profit margin reached a peak of 16.25% in 2019 before dropping to 9.36% in 2020. While a recovery to 11.92% was achieved in 2021, the margin contracted to 9.76% by 2022. A parallel trend is observed in the reported net profit margin, which fluctuated between a high of 12.58% in 2019 and a low of 7.17% in 2020, ending the period at 7.69%.

Variance Between Reported and Adjusted Metrics

A consistent positive variance exists between adjusted and reported margins throughout the five-year period. The adjusted net profit margin remained several percentage points higher than the reported margin in every observed year, indicating that non-recurring items or specific tax-related adjustments consistently exerted a downward pressure on reported profitability.

Profitability Divergence

A divergence is noted between 2021 and 2022, where absolute net income continued to grow while both reported and adjusted net profit margins declined. This suggests that the growth in net income during the final year did not keep pace with the growth in overall revenue, resulting in reduced operational efficiency relative to sales.

Between 2018 and 2022, a divergent trend is observed between reported and adjusted shareholders' equity, which directly influences the calculated financial leverage. While reported equity experienced a period of contraction followed by a partial recovery, adjusted equity demonstrated greater stability and accelerated growth toward the end of the period.

Shareholders' Equity Trends

Reported shareholders' equity declined from 6,579,543 thousand USD in 2018 to a minimum of 6,015,163 thousand USD in 2021, before recovering to 6,493,885 thousand USD in 2022. In contrast, adjusted shareholders' equity remained relatively stable from 2018 through 2020, followed by a significant upward trajectory, reaching 7,181,853 thousand USD in 2021 and 8,232,410 thousand USD by 2022. The widening variance between reported and adjusted figures indicates an increasing impact of adjustments on the equity base over time.

Financial Leverage Analysis

Reported financial leverage showed a consistent increase from 2.77 in 2018 to a peak of 3.93 in 2021, before moderating to 3.75 in 2022. Adjusted financial leverage followed a different trajectory, peaking earlier at 3.44 in 2020 and subsequently declining to 2.96 by 2022. Throughout the entire five-year period, the adjusted leverage ratio remained consistently lower than the reported ratio.

The utilization of adjusted equity provides a more favorable representation of the company's solvency and capital structure. By 2022, the disparity between reported and adjusted leverage became more pronounced, suggesting that the adjustments—likely related to deferred tax liabilities—effectively reduce the perceived financial risk and result in a lower leverage profile than what is presented in the reported financial statements.

The financial performance from 2018 through 2022 is characterized by a significant volatility peak in 2020, followed by a robust recovery and expansion in profitability. A consistent positive variance is observed between reported and adjusted figures, indicating that non-recurring items or specific accounting adjustments regularly impact the reported net income and equity levels.

Net Income Trends

Reported net income experienced a sharp decline in 2020, falling to 612.8 million USD from 1.28 billion USD in 2019. However, a strong recovery followed, with reported net income reaching 1.72 billion USD by 2022. Adjusted net income consistently exceeded reported figures throughout the period, peaking at 2.19 billion USD in 2022, which suggests that the adjustments remove significant expenses or losses that would otherwise depress reported earnings.

Shareholders' Equity Dynamics

Reported shareholders' equity remained relatively stable between 2018 and 2021, fluctuating between 6.02 billion USD and 6.58 billion USD, before increasing to 6.49 billion USD in 2022. In contrast, adjusted shareholders' equity showed a more pronounced upward trend in the latter part of the period, growing from 6.71 billion USD in 2020 to 8.23 billion USD in 2022. This widening gap indicates a growing divergence between reported book value and adjusted equity measures.

Return on Equity (ROE) Analysis

Both reported and adjusted ROE followed a mirrored trajectory, with a notable trough in 2020 where reported ROE dropped to 10.14% and adjusted ROE to 11.91%. Following this decline, a rapid acceleration occurred, with reported ROE climbing to 26.52% by 2022. While adjusted ROE was typically higher than reported ROE from 2018 to 2021, the two metrics converged almost entirely by 2022, with reported ROE at 26.52% and adjusted ROE at 26.55%.

The convergence of reported and adjusted ROE in 2022, despite the significant difference in the absolute values of adjusted versus reported net income and equity, indicates that the adjustments to the numerator and denominator scaled proportionally. The overall trend reflects a substantial increase in capital efficiency and profitability returning to, and exceeding, pre-2020 levels.

The financial performance from 2018 through 2022 is characterized by a significant volatility event in 2020, followed by a period of strong recovery and growth. A consistent positive variance is observed between reported and adjusted figures, indicating that non-recurring items or specific accounting adjustments systematically reduce reported profitability and asset efficiency relative to adjusted metrics.

Net Income Trajectory

Reported net income exhibited a fluctuating trend, declining from 1.15 billion USD in 2018 to a trough of 612.8 million USD in 2020, before ascending to a period high of 1.72 billion USD in 2022. Adjusted net income followed a similar trajectory but remained consistently higher, peaking at 2.19 billion USD in 2022. The gap between reported and adjusted net income was most pronounced in 2022, suggesting an increase in the impact of the adjustments used to derive the adjusted figure.

Adjusted Return on Assets (ROA) Trends

Adjusted ROA demonstrates a V-shaped recovery over the analyzed period. After starting at 8.30% in 2018 and dipping to 7.57% in 2019, the ratio fell sharply to 3.46% in 2020. A subsequent recovery saw the ratio climb to 8.35% in 2021 and reach a maximum of 8.97% by 2022. This indicates that the efficiency of asset utilization, when adjusted for non-recurring items, improved beyond pre-2020 levels by the end of the period.

Comparative Analysis of Reported vs. Adjusted ROA

A persistent divergence exists between reported ROA and adjusted ROA across all years. Reported ROA mirrored the adjusted trend, falling from 6.32% in 2018 to 2.66% in 2020 before recovering to 7.06% in 2022. The adjusted ROA consistently provides a higher valuation of performance, typically maintaining a spread of approximately 1.6 to 2.0 percentage points over the reported ROA. This suggests that the underlying operational asset efficiency is stronger than the reported statutory figures indicate.
