Based on: 10-K (reporting date: 2021-12-31), 10-K (reporting date: 2020-12-31), 10-K (reporting date: 2019-12-31), 10-K (reporting date: 2018-12-31), 10-K (reporting date: 2017-12-31).


The income tax profile exhibits significant volatility over the five-year period ending December 31, 2021. The total provision for income taxes shifted from a modest tax benefit in 2017 to a substantial tax benefit in 2020, followed by a sharp reversal to a tax expense in 2021. This volatility is primarily attributed to fluctuations in deferred tax accounts rather than current tax obligations.

Total Income Tax Provision Trends
The overall provision for income taxes demonstrated extreme fluctuations. After recording a benefit of 20 million US$ in 2017 and expenses of 168 million US$ and 47 million US$ in 2018 and 2019 respectively, the company recognized a substantial tax benefit of 1,104 million US$ in 2020. This trend reversed abruptly in 2021 with a tax provision of 631 million US$, marking a net swing of 1,735 million US$ over two years.
Analysis of Deferred Income Tax Components
Deferred tax provisions acted as the primary driver of the total tax expense or benefit. The deferred component closely mirrors the total provision, most notably in 2020, where a deferred tax benefit of 1,042 million US$ accounted for nearly the entire tax benefit of the year. Similarly, in 2021, the deferred tax provision of 606 million US$ constituted the vast majority of the total tax expense.
Current Income Tax Provision Stability
In contrast to the deferred components, current income tax provisions remained relatively immaterial and stable. These values fluctuated within a narrow range, from a maximum provision of 25 million US$ in 2021 to a maximum benefit of 62 million US$ in 2020, indicating that the immediate cash-basis tax liabilities did not contribute significantly to the overall volatility of the income tax expense.

Effective income tax rate 21.70% 19.10% 13.00% 151.00% -3.93%

Based on: 10-K (reporting date: 2021-12-31), 10-K (reporting date: 2020-12-31), 10-K (reporting date: 2019-12-31), 10-K (reporting date: 2018-12-31), 10-K (reporting date: 2017-12-31).


The analysis of income tax metrics reveals a significant shift in the statutory tax environment and substantial volatility in the effective income tax rate over the five-year period from 2017 to 2021.

Federal Statutory Tax Rate
A permanent reduction in the federal statutory tax rate is observed between 2017 and 2018, where the rate decreased from 35.00% to 21.00%. Following this adjustment, the statutory rate remained constant at 21.00% through the end of 2021.
Effective Income Tax Rate Volatility
The effective income tax rate exhibited extreme fluctuations during the early part of the period. In 2017, a negative rate of -3.93% indicates a tax benefit or the impact of tax credits. This was followed by an anomalous spike to 151.00% in 2018, suggesting significant one-time tax adjustments, potentially related to the revaluation of deferred tax assets and liabilities following the change in the federal statutory rate.
Normalization and Convergence
Starting in 2019, the effective income tax rate began to stabilize and converge toward the statutory rate. After dropping to 13.00% in 2019, the rate climbed to 19.10% in 2020 and reached 21.70% by 2021. This progression indicates a return to normalized tax operations, with the 2021 rate closely aligning with the 21.00% federal statutory benchmark.

Based on: 10-K (reporting date: 2021-12-31), 10-K (reporting date: 2020-12-31), 10-K (reporting date: 2019-12-31), 10-K (reporting date: 2018-12-31), 10-K (reporting date: 2017-12-31).


The net deferred tax position shifted from a relatively small liability of 108 million US dollars in 2017 to a substantial net deferred tax liability of 1,298 million US dollars by 2021. This trajectory was characterized by a sharp increase in liabilities through 2019, a partial reversal in 2020, and a subsequent increase in 2021.

Deferred Tax Assets (DTA) Components
Gross deferred tax assets experienced consistent growth, rising from 101 million US dollars in 2017 to 948 million US dollars in 2021. The primary driver of this increase was the escalation of net operating loss and other carryforwards, which grew from 75 million US dollars to 682 million US dollars over the period. Additionally, the investment in Viper LLC emerged as a significant contributor, increasing from 94 million US dollars in 2018 to 163 million US dollars by 2021.
Valuation Allowance Trends
While gross assets increased, the application of valuation allowances grew more aggressive in later years. After remaining negligible or minimal between 2017 and 2019, the valuation allowance expanded significantly to 166 million US dollars in 2020 and 315 million US dollars in 2021. This resulted in a deceleration of the growth of net deferred tax assets, which peaked at 641 million US dollars in 2020 before declining to 633 million US dollars in 2021.
Deferred Tax Liabilities (DTL) Drivers
Deferred tax liabilities are dominated by oil and natural gas properties and equipment. This item saw a dramatic increase from 203 million US dollars in 2017 to a peak of 2,275 million US dollars in 2019, before fluctuating to 1,702 million US dollars in 2021. Midstream investments also exhibited a steady upward trend in liability, growing from 6 million US dollars in 2017 to 224 million US dollars in 2021.
Net Deferred Tax Position
The overall net position reflects a volatility in the company's long-term tax obligations. The net deferred tax liability reached its zenith in 2019 at 1,744 million US dollars. A notable contraction occurred in 2020, where the net liability decreased to 710 million US dollars, primarily due to a significant temporary reduction in liabilities related to oil and natural gas properties and equipment. However, by 2021, the net liability expanded again to 1,298 million US dollars, driven by a resurgence in property-related liabilities and an increased valuation allowance against assets.

The removal of deferred taxes results in a systematic modification of the balance sheet and income statement, primarily through the reduction of both deferred tax assets and deferred tax liabilities. This adjustment alters the perceived capital structure and the reported profitability of the organization over the five-year period analyzed.

Balance Sheet Asset and Liability Adjustments
A consistent pattern is observed where adjusted total assets are lower than reported total assets from 2018 through 2021. The magnitude of this reduction is relatively small compared to the overall asset base, peaking in 2019. Conversely, a more substantial reduction is observed in liabilities. Adjusted total liabilities are significantly lower than reported liabilities in every year of the analysis. The most pronounced divergence occurred in 2018 and 2019, where reported liabilities exceeded adjusted liabilities by approximately 1.7 billion to 1.8 billion US dollars.
Impact on Stockholders' Equity
The removal of deferred taxes leads to a consistent increase in stockholders' equity. Because the reduction in reported liabilities exceeds the reduction in reported assets, the net effect is a positive adjustment to the equity position. This trend is evident across all years, with the highest equity uplift occurring in 2018 and 2019. This suggests that the company's reported financial position carries a significant deferred tax liability that, when removed, improves the net book value of the equity.
Net Income Volatility and Tax Adjustments
The relationship between reported and adjusted net income varies significantly over the period. In 2018, 2019, and 2021, the adjusted net income is higher than the reported figures, indicating that the removal of deferred tax expenses improves the reported bottom line. However, during the significant loss recorded in 2020, the adjusted net loss was substantially deeper than the reported loss, shifting from a reported loss of 4.5 billion US dollars to an adjusted loss of 5.5 billion US dollars. This indicates that deferred tax credits or benefits provided a buffer in the reported statements that is absent in the adjusted figures.
Overall Financial Position Trend
The adjustment process reveals a more leveraged reported balance sheet than the adjusted one. By removing the deferred tax components, the company exhibits a stronger equity ratio and a lower liability profile. The volatility in net income is further amplified in the adjusted figures, particularly during periods of financial distress, suggesting that deferred tax accounting serves to smooth the impact of earnings volatility on the reported financial statements.

Based on: 10-K (reporting date: 2021-12-31), 10-K (reporting date: 2020-12-31), 10-K (reporting date: 2019-12-31), 10-K (reporting date: 2018-12-31), 10-K (reporting date: 2017-12-31).


The financial performance between 2017 and 2021 is characterized by significant volatility, with a severe contraction in profitability occurring in 2020 followed by a robust recovery in 2021. The removal of deferred taxes for adjusted ratios generally amplifies these fluctuations, suggesting that deferred tax accounting served as a smoothing mechanism for reported results during both peak and trough periods.

Profitability Margins
Net profit margins exhibited extreme variance, plummeting from reported levels of approximately 40% in 2017 and 2018 to a deficit of -163.90% in 2020. Adjusted net profit margins intensified this volatility; for instance, the 2020 deficit deepened to -201.71% when deferred taxes were removed. Conversely, the recovery in 2021 was more pronounced in the adjusted figures, reaching 41.32% compared to the reported 32.34%.
Asset Efficiency and Leverage
Total asset turnover remained relatively stable and showed minimal divergence between reported and adjusted figures, with a notable increase observed in 2021 where the adjusted ratio reached 0.30. Financial leverage showed a steady upward trend from 2017, peaking in 2020 at a reported 2.00. In all periods, adjusted financial leverage remained lower than reported leverage, indicating that deferred tax liabilities contribute significantly to the reported equity base and leverage calculations.
Returns on Equity and Assets
Both Return on Equity (ROE) and Return on Assets (ROA) mirrored the volatility of the profit margins. Reported ROE fell from 9.18% in 2017 to -51.36% in 2020, before rebounding to 18.05% in 2021. The adjusted ROE experienced more extreme swings, reaching a lower trough of -58.49% in 2020 and a higher peak of 20.83% in 2021. A similar pattern is evident in ROA, where adjusted figures were more severely negative during the 2020 downturn (-31.68% vs -25.64%) but stronger during the 2021 recovery (12.20% vs 9.53%).

Overall, the adjustment for deferred taxes reveals a higher degree of underlying operational sensitivity to market conditions. The consistent gap in financial leverage and the amplified returns indicate that the tax treatment has a material impact on the perceived stability of the balance sheet and the efficiency of capital deployment.

2021 Calculations

1 Net profit margin = 100 × Net income (loss) attributable to Diamondback Energy, Inc. ÷ Revenue from contracts with customers
= 100 × 2,182 ÷ 6,747 = 32.34%

2 Adjusted net profit margin = 100 × Adjusted net income (loss) attributable to Diamondback Energy, Inc. ÷ Revenue from contracts with customers
= 100 × 2,788 ÷ 6,747 = 41.32%


The financial performance of Diamondback Energy Inc. from 2017 to 2021 is characterized by extreme volatility, featuring a period of growth, a severe contraction, and a subsequent robust recovery. Net income and profit margins exhibited sharp fluctuations, reflecting significant sensitivity to market conditions during this five-year interval.

Adjusted Net Profit Margin Trends
The adjusted net profit margin experienced a peak of 47.66% in 2018, rising from 38.92% in 2017. A sharp decline followed, with the margin falling to 7.38% in 2019 and reaching a critical low of -201.71% in 2020. A strong recovery is observed in 2021, where the adjusted net profit margin rebounded to 41.32%, returning the company to a profitability level comparable to the 2017-2018 period.
Reported versus Adjusted Performance
Variances between reported and adjusted net income metrics are persistent. In 2018 and 2021, adjusted net income was higher than reported net income, with the gap being most pronounced in 2021 (2,788 million US$ adjusted vs. 2,182 million US$ reported). In contrast, the 2020 fiscal year showed a deeper loss on an adjusted basis (5,559 million US$) compared to the reported loss (4,517 million US$), indicating that specific adjustments exacerbated the recognized deficit during the downturn.
Analysis of Profitability Volatility
The transition from 2020 to 2021 represents a significant reversal in financial trajectory. The reported net profit margin shifted from -163.90% to 32.34% within a single year, and the reported net income moved from a loss of 4,517 million US$ to a profit of 2,182 million US$. This suggests a rapid restoration of margins and an effective recovery of the company's earnings capacity following the anomalies of 2020.

2021 Calculations

1 Total asset turnover = Revenue from contracts with customers ÷ Total assets
= 6,747 ÷ 22,898 = 0.29

2 Adjusted total asset turnover = Revenue from contracts with customers ÷ Adjusted total assets
= 6,747 ÷ 22,858 = 0.30


The financial data reflects a period of significant asset base volatility and a subsequent improvement in asset utilization efficiency between 2017 and 2021.

Total Asset Base Trends
A substantial increase in total assets is observed between 2017 and 2018, where reported assets rose from 7,771 million to 21,596 million. This growth peaked in 2019 at 23,531 million before experiencing a contraction to 17,619 million in 2020. A recovery followed in 2021, with reported assets increasing to 22,898 million. Adjusted total assets closely mirrored these movements, indicating that the adjustments made had a negligible impact on the overall asset valuation.
Asset Turnover Performance
The reported total asset turnover ratio exhibited a decline from 0.15 in 2017 to a low of 0.10 in 2018, coinciding with the rapid expansion of the asset base. Efficiency levels stabilized between 2019 and 2020, holding at 0.17 and 0.16, respectively. A significant upward trend is noted in 2021, where the reported ratio rose to 0.29, representing the highest level of efficiency in the analyzed period.
Comparative Analysis of Adjusted Metrics
The adjusted total asset turnover ratio remained consistent with reported figures throughout the period, following the same trajectory of a dip in 2018 and a peak in 2021. In 2021, the adjusted turnover ratio reached 0.30, slightly exceeding the reported ratio of 0.29. This minimal variance suggests that the adjustments applied to the assets did not materially alter the interpretation of the company's operational efficiency in utilizing its assets to generate revenue.

2021 Calculations

1 Financial leverage = Total assets ÷ Total Diamondback Energy, Inc. stockholders’ equity
= 22,898 ÷ 12,088 = 1.89

2 Adjusted financial leverage = Adjusted total assets ÷ Adjusted total Diamondback Energy, Inc. stockholders’ equity
= 22,858 ÷ 13,386 = 1.71


An examination of the balance sheet metrics from 2017 to 2021 reveals significant fluctuations in total assets and stockholders' equity. Total assets experienced a substantial increase between 2017 and 2019, followed by a contraction in 2020 and a subsequent recovery in 2021. Stockholders' equity followed a similar trajectory, peaking in 2018 and experiencing its lowest point of the period in 2020.

Reported Financial Leverage Trends
The reported financial leverage ratio demonstrated a consistent upward trend from 2017 to 2020, rising from 1.48 to a peak of 2.00. This indicates an increasing reliance on debt relative to equity over this four-year span, before a slight correction to 1.89 occurred in 2021.
Adjusted Financial Leverage Trends
The adjusted financial leverage ratio remained consistently lower than the reported ratio from 2018 through 2021. Although it mirrored the overall peak in 2020 at 1.85, the adjusted metric showed greater stability in the early period, specifically decreasing to 1.40 in 2018 while the reported ratio was increasing.
Impact of Adjustments on Leverage
A consistent disparity is observed between reported and adjusted stockholders' equity, with adjusted equity remaining higher than reported equity in every period from 2017 to 2021. This increase in the equity base within the adjusted calculations results in a lower financial leverage ratio. This suggests that the adjustments, likely related to the treatment of income tax liabilities, mitigate the perceived leverage of the entity.
Asset and Equity Correlation
The peak leverage observed in 2020 for both reported (2.00) and adjusted (1.85) ratios coincides with the period of lowest total assets and lowest stockholders' equity since 2017. The recovery of these values in 2021 contributed to the subsequent decline in both leverage ratios.

1 ROA = 100 × Net income (loss) attributable to Diamondback Energy, Inc. ÷ Total assets
= 100 × 2,182 ÷ 22,898 = 9.53%

2 Adjusted ROA = 100 × Adjusted net income (loss) attributable to Diamondback Energy, Inc. ÷ Adjusted total assets
= 100 × 2,788 ÷ 22,858 = 12.20%


The financial performance from 2017 through 2021 is characterized by extreme volatility in earnings and a fluctuating asset base, resulting in wide swings in return on assets (ROA).

Net Income Variability
Reported net income exhibited a peak in 2018 before declining sharply. A significant deficit occurred in 2020, with reported losses reaching 4,517 million US dollars, while adjusted net income showed an even deeper loss of 5,559 million US dollars. A robust recovery followed in 2021, with adjusted net income rising to 2,788 million US dollars.
Asset Base Dynamics
A substantial increase in total assets occurred between 2017 and 2018, where adjusted assets rose from 7,771 million US dollars to 21,499 million US dollars. Assets reached a peak in 2019 at 23,389 million US dollars before contracting to 17,546 million US dollars in 2020 and rebounding to 22,858 million US dollars by the end of 2021.
Adjusted ROA Interpretation
The adjusted ROA demonstrates more pronounced volatility than the reported ROA. Following a gradual decline from 5.94% in 2017 to 1.23% in 2019, the metric plummeted to -31.68% in 2020, reflecting the combined impact of significant net losses and a reduced asset base. By 2021, the adjusted ROA reached its highest level in the observed period at 12.20%, indicating a strong recovery in profitability relative to the asset base.
