Pioneer Natural Resources Company (NYSE:PXD) ("Pioneer" or "the Company") today reported financial and operating results for the quarter ended June 30, 2021. Pioneer reported second quarter net income attributable to common stockholders of $380 million, or $1.54 per diluted share. These results include the effects of noncash mark-to-market adjustments and certain other unusual items. Excluding these items, non-GAAP adjusted income for the second quarter was $629 million, or $2.55 per diluted share. Cash flow from operating activities for the second quarter was $1.5 billion.

Highlights

Delivered strong second quarter free cash flow¹ of $616 million

Accelerated and increased variable dividend program; future variable dividend payments² up to 75% of prior quarter's free cash flow after deducting the base dividend paid during the quarter

Declared inaugural variable dividend of $1.51 per share to be paid during the third quarter; represents approximately 75% of second quarter free cash flow after deducting the base dividend paid in April

Averaged second quarter oil production of 363 thousand barrels of oil per day (MBOPD), in the upper half of guidance

Averaged second quarter production of 629 thousand barrels of oil equivalent per day (MBOEPD), near the top end of guidance

CEO Scott D. Sheffield stated, "Pioneer delivered a strong quarter as we integrated DoublePoint operations into our asset base, while continuing to execute one of the most efficient capital programs in the industry.

We are witnessing strong oil demand growth as the global macroeconomic environment continues to improve, with a corresponding improvement in commodity prices. As a result of the improved commodity price outlook, which is expected to further strengthen our balance sheet, we have accelerated and increased our variable dividend return framework with the declaration of our inaugural variable dividend.

This inaugural variable dividend, combined with our base dividend, represents a significant return of capital to shareholders, with approximately 80% of our second quarter free cash flow being returned to shareholders. This announcement accelerates our long-term commitment to return capital to shareholders under our investment framework. Over the next six years, we expect to generate in excess of $23 billion of cumulative free cash flow¹ based on current commodity prices, creating a compelling and durable value proposition for our shareholders."

Financial Highlights

Pioneer maintains a strong balance sheet, with unrestricted cash on hand at the end of the second quarter of $93 million and net debt of $6.8 billion. The Company had $2.1 billion of liquidity as of June 30, 2021, comprised of $93 million of unrestricted cash and a $2.0 billion unsecured credit facility (undrawn as of June 30, 2021).

During the second quarter, the Company's drilling, completion and facilities capital expenditures totaled $883 million. The Company's total capital expenditures³, including water infrastructure, totaled $900 million.

Cash flow from operating activities during the second quarter was $1.5 billion, leading to free cash flow¹ of $616 million for the second quarter.

The rebound in global oil demand has led to higher commodity prices, further strengthening Pioneer's balance sheet and enabling the Company to accelerate its first variable dividend payment from the first quarter of 2022. The Company now expects to distribute a quarterly variable dividend of up to 75% of the prior quarter's free cash flow after deducting the base dividendpaid during the quarter². In light of the improved outlook, the Board of Directors has declared Pioneer's inaugural variable dividend of $1.51 per share, or approximately $370 million being returned to shareholders, representing approximately 75% of the Company's second quarter free cash flow after deducting the base dividend distributed in April. The Company believes this differentiated return of capital strategy, which combines a base dividend with a substantial variable dividend, creates significant value for shareholders².

Pioneer continues to capture the expected annual synergies from the acquisition of Parsley Energy Inc. (Parsley) and DoublePoint Energy (DoublePoint), with expected combined annual synergies totaling $525 million and a PV-10 of greater than $3 billion over ten years. The Company is progressing on these synergies, with $160 million of annual interest savings and $115 million of general and administrative (G&A) savings between Parsley and DoublePoint being fully realized. The operational synergies related to both transactions continue to progress and are expected to be fully realized by year-end 2021.

Financial Results

For the second quarter of 2021, the average realized price for oil was $64.55 per barrel. The average realized price for natural gas liquids (NGLs) was $27.95 per barrel, and the average realized price for gas was $2.69 per thousand cubic feet. These prices exclude the effects of derivatives.

Production costs, including taxes, averaged $8.18 per barrel of oil equivalent (BOE). Depreciation, depletion and amortization (DD&A) expense averaged $11.31 per BOE. Exploration and abandonment costs were $10 million. G&A expense was $75 million. Interest expense was $41 million. The net cash flow impact related to purchases and sales of oil and gas, including firm transportation, was a loss of $40 million, or a loss $53 million when including the cash flow impact from the Company's firm transportation marketing contracts that are accounted for as derivatives. Other expense was $47 million, or $14 million excluding unusual items⁴.

Operations Update

During the second quarter, Pioneer continued to deliver strong operational efficiency gains that enabled the Company to place 157 horizontal wells on production. Drilling and completion efficiencies continued to improve, with an increase of greater than 65% drilled feet per day and 75% completed feet per day when compared to 2017 averages. The Company continues to see benefits of utilizing simulfrac technology and now plans to run two simulfrac fleets during the second half of 2021. These efficiency and cost improvements in drilling and completions continue to benefit the Company's overall capital efficiency and dampen inflationary pressures. Additionally, Pioneer continues to upgrade the acquired Parsley and DoublePoint facilities to Pioneer's high operational and environmental standards.

2021 Outlook

The Company expects its 2021 drilling, completions and facilities capital budget to range between $2.95 billion to $3.25 billion. An additional $100 million and $50 million is budgeted for integration expenses related to the acquisition of Parsley and DoublePoint, respectively, resulting in a total 2021 capital budget³ range of $3.1 billion to $3.4 billion. The Company expects its capital program to be fully funded from forecasted 2021 cash flow⁵ of approximately $6.45 billion.

During 2021, the Company plans to operate an average of 22 to 24 horizontal drilling rigs in the Permian Basin, including a one-rig average program in the Delaware Basin and a three-rig average program in the southern Midland Basin joint venture area. The 2021 capital program is expected to place 470 to 510 wells on production. Pioneer expects 2021 oil production of 351 to 366 MBOPD and total production of 605 to 631 MBOEPD.

Pioneer's investment framework prioritizes free cash flow generation and return of capital to shareholders. This capital allocation strategy is intended to create long-term value by optimizing the reinvestment of cash flow to accelerate the Company's free cash flow profile. The Company expects its reinvestment rate to be between 50% to 60%, generating increased free cash flow. This investment framework is expected to deliver a mid-teens total annual return, inclusive of a strong and growing base dividend, a variable dividend and high-return oil growth of up to five percent. The Company believes this differentiated strategy positions Pioneer to be competitive across industries.

The Company's financial and derivative mark-to-market results and open derivatives positions are outlined in the attached schedules.

Third Quarter 2021 Guidance

Third quarter 2021 oil production is forecasted to average between 380 to 395 MBOPD and total production is expected to average between 660 to 685 MBOEPD. Production costs are expected to average $7.25 per BOE to $8.75 per BOE, with the increase primarily reflecting the impact of higher forecasted commodity prices on production taxes and gas and NGL processing fees. DD&A expense is expected to average $10.75 per BOE to $12.75 per BOE. Total exploration and abandonment expense is forecasted to be $10 million to $20 million. G&A expense is expected to be $67 million to $77 million. Interest expense is expected to be $39 million to $44 million. Other expense is forecasted to be $15 million to $30 million. Accretion of discount on asset retirement obligations is expected to be $2 million to $5 million. The cash flow impact related to purchases and sales of oil and gas, including firm transportation, is expected to be a loss of $35 million to $65 million, based on forward oil price estimates for the quarter. The Company's effective income tax rate is expected to be between 22% to 27%. Cash income taxes are expected to be $5 million to $15 million, principally related to forecasted state income taxes.

Environmental, Social & Governance (ESG)

Pioneer views sustainability as a multidisciplinary focus that balances economic growth, environmental stewardship and social responsibility. The Company emphasizes developing natural resources in a manner that protects surrounding communities and preserves the environment.

Consistent with Pioneer's sustainable practices, the Company has incorporated greenhouse gas (GHG) and methane emission intensity reduction goals into its ESG strategy, with goals to reduce the Company's GHG emissions intensity by 25% and methane emissions intensity by 40% by 2030. These emission intensity reduction targets are aligned with the Task Force on Climate-related Financial Disclosures criteria for target setting.

In addition, the Company is building on its leadership position related to minimizing flaring and has formally adopted a goal to maintain the Company's flaring intensity to less than 1% of natural gas produced. Pioneer also plans to end routine flaring, as defined by the World Bank, by 2030 with an aspiration to reach this goal by 2025.

Socially, Pioneer maintains a proactive safety culture, supports a diverse workforce and inspires teamwork to drive innovation. The Board of Directors and its committees provide director-level oversight of these activities. These committees help to promote a culture of continuous improvement in the Company's diversity, equity and inclusion practices, along with the Company's safety and environmental practices. Consistent with the high priority placed on Health, Safety and Environment (HSE) and ESG, the Board of Directors has increased the executive annual incentive compensation weighting for these metrics from 10% to 20% for 2021.

In addition to the increased weighting towards HSE and ESG metrics, Pioneer's executive incentive compensation continues to be aligned with shareholder interests. Beginning in 2021, return on capital employed (ROCE) has been included as an incentive compensation metric, along with cash return on capital invested (CROCI), which was added in 2020. These metrics have a combined weighting of 20%, while production and reserves goals previously included as incentive compensation metrics have been removed.

Pioneer has amended executive equity compensation as well, with the S&P 500 index being added into the total stockholder return (TSR) peer group for performance awards beginning in 2021, and for the second consecutive year, the long-term equity compensation for the Company's Chief Executive Officer will be 100% in performance awards, with 100% of such awards at risk based on performance relative to the TSR peer group. These updates to Pioneer's executive incentive and equity compensation programs demonstrate the Company's continuing commitment to aligning total executive compensation with the interests of our shareholders.

Except for historical information contained herein, the statements in this news release are forward-looking statements that are made pursuant to the Safe Harbor Provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements and the business prospects of Pioneer are subject to a number of risks and uncertainties that may cause Pioneer's actual results in future periods to differ materially from the forward-looking statements. These risks and uncertainties include, among other things, volatility of commodity prices; product supply and demand; the impact of a widespread outbreak of an illness, such as the COVID-19 pandemic, on global and U.S. economic activity; competition; the ability to obtain environmental and other permits and the timing thereof; the effect of future regulatory or legislative actions on Pioneer or the industry in which it operates, including the risk of new restrictions with respect to development activities; the ability to obtain approvals from third parties and negotiate agreements with third parties on mutually acceptable terms; potential liability resulting from pending or future litigation; the costs and results of drilling and operations; availability of equipment, services, resources and personnel required to perform the Company's drilling and operating activities; access to and availability of transportation, processing, fractionation, refining, storage and export facilities; Pioneer's ability to replace reserves, implement its business plans or complete its development activities as scheduled; the risk that the Company will not fully or timely realize the expected synergies and accretion metrics from the Parsley Energy, Inc. and Double Eagle III Midco 1 LLC acquisitions; access to and cost of capital; the financial strength of counterparties to Pioneer's credit facility, investment instruments and derivative contracts and purchasers of Pioneer's oil, natural gas liquids and gas production; uncertainties about estimates of reserves, identification of drilling locations and the ability to add proved reserves in the future; the Company's ability to achieve its emissions reduction and flaring goals; the assumptions underlying forecasts, including forecasts of production, well costs, capital expenditures, expenses, rates of return, cash flow and cash flow from purchases and sales of oil and gas, net of firm transportation commitments; sources of funding; tax rates; quality of technical data; environmental and weather risks, including the possible impacts of climate change; cybersecurity risks; the risks associated with the ownership and operation of the Company's water services business and acts of war or terrorism. These and other risks are described in Pioneer's Annual Report on Form 10-K for the year ended December 31, 2020, Quarterly Reports on Form 10-Q filed thereafter and other filings with the United States Securities and Exchange Commission. In addition, the Company may be subject to currently unforeseen risks that may have a materially adverse effect on it. Accordingly, no assurances can be given that the actual events and results will not be materially different than the anticipated results described in the forward-looking statements. Pioneer undertakes no duty to publicly update these statements except as required by law.

Footnote 1: Free cash flow is a non-GAAP financial measure. As used by the Company, free cash flow is defined as net cash provided by operating activities, adjusted for changes in operating assets and liabilities and cash acquisition transaction costs, less capital expenditures. See the supplemental schedules for a reconciliation of second quarter 2021 free cash flow to the comparable GAAP number. Forecasted free cash flow numbers are non-GAAP financial measures. Due to their forward-looking nature, management cannot reliably predict certain of the necessary components of the most directly comparable forward-looking GAAP measures, such as working capital changes. Accordingly, Pioneer is unable to present a quantitative reconciliation of such forward-looking non-GAAP financial measures to their most directly comparable forward-looking GAAP financial measures. Amounts excluded from this non-GAAP measure in future periods could be significant.

Footnote 2: Future dividends, whether variable or base, are authorized and determined by the Company's board of directors in its sole discretion. Decisions regarding the payment of dividends are subject to a number of considerations at the time, including without limitation the Company's liquidity and capital resources, the Company's results of operations and anticipated future results of operations, the level of cash reserves the Company may establish to fund future capital expenditures or other needs, and other factors the board of directors deems relevant. The Company can provide no assurance that dividends will be authorized or declared in the future or the amount of any future dividends. Any future variable dividends, if declared and paid, will by their nature fluctuate based on the Company's free cash flow, which will depend on a number of factors beyond the Company's control, including commodities prices.

Footnote 3: Excludes acquisitions, asset retirement obligations, capitalized interest, geological and geophysical G&A, information technology and corporate facilities.

Footnote 4: Excludes unusual expenses of (i) $27 million associated with the DoublePoint acquisition and (ii) $9 million associated with the Parsley acquisition; offset by a $3 million gain related to the early extinguishment of DoublePoint senior notes.

Footnote 5: Estimated cash flow numbers are non-GAAP financial measures. The 2021 estimated cash flow number represents first half 2021 cash flow (before changes in operating assets and liabilities and cash acquisition transaction costs) plus July through December forecasted cash flow (before changes in operating assets and liabilities) based on strip pricing and utilizing the midpoint of production guidance. Due to their forward-looking nature, management cannot reliably predict certain of the necessary components of the most directly comparable forward-looking GAAP measures, such as changes in operating assets and liabilities. Accordingly, Pioneer is unable to present a quantitative reconciliation of such forward-looking non-GAAP financial measures to their most directly comparable forward-looking GAAP financial measures. Amounts excluded from this non-GAAP measure in future periods could be significant.

Note: Estimates of future results, including cash flow and free cash flow, are based on the Company's internal financial model prepared by management and used to assist in the management of its business. Pioneer's financial models are not prepared with a view to public disclosure or compliance with GAAP, any guidelines of the SEC or any other body. The financial models reflect numerous assumptions, in addition to those noted in this news release, with respect to general business, economic, market and financial conditions and other matters. These assumptions regarding future events are difficult, if not impossible to predict, and many are beyond Pioneer's control. Accordingly, there can be no assurance that the assumptions made by management in preparing the financial models will prove accurate. It is expected that there will be differences between actual and estimated or modeled results, and actual results may be materially greater or less than those contained in the Company's financial models.

PIONEER NATURAL RESOURCES COMPANY UNAUDITED SUPPLEMENTARY EARNINGS PER SHARE INFORMATION (in millions)

The Company uses the two-class method of calculating basic and diluted earnings per share. Under the two-class method of calculating earnings per share, generally acceptable accounting principles ("GAAP") provide that share-based awards with guaranteed dividend or distribution participation rights qualify as "participating securities" during their vesting periods. During periods in which the Company realizes net income attributable to common shareholders, the Company's basic net income per share attributable to common shareholders is computed as (i) net income attributable to common stockholders, (ii) less participating share-based basic earnings (iii) divided by weighted average basic shares outstanding. The Company's diluted net income per share attributable to common stockholders is computed as (i) basic net income attributable to common stockholders, (ii) plus the reallocation of participating earnings, if any, (iii) plus the after-tax interest expense associated with the Company's convertible senior notes that are assumed to be converted into shares (iv) divided by weighted average diluted shares outstanding. During periods in which the Company realizes a net loss attributable to common stockholders, securities or other contracts to issue common stock would be dilutive to loss per share; therefore, conversion into common stock is assumed not to occur. The Company's net income (loss) attributable to common stockholders is reconciled to basic and diluted net income (loss) attributable to common stockholders as follows:

PIONEER NATURAL RESOURCES COMPANY UNAUDITED SUPPLEMENTAL NON-GAAP FINANCIAL MEASURES (in millions)

EBITDAX and discretionary cash flow ("DCF") (as defined below) are presented herein, and reconciled to the GAAP measures of net income (loss) and net cash provided by operating activities, because of their wide acceptance by the investment community as financial indicators of a company's ability to internally fund exploration and development activities and to service or incur debt. The Company also views the non-GAAP measures of EBITDAX and DCF as useful tools for comparisons of the Company's financial indicators with those of peer companies that follow the full cost method of accounting. EBITDAX and DCF should not be considered as alternatives to net income (loss) or net cash provided by operating activities, as defined by GAAP.

PIONEER NATURAL RESOURCES COMPANY UNAUDITED SUPPLEMENTAL NON-GAAP FINANCIAL MEASURES (continued) (in millions, except per share data)

Adjusted income attributable to common stockholders excluding noncash mark-to-market ("MTM") adjustments and unusual items are presented in this earnings release and reconciled to the Company's net income attributable to common stockholders (determined in accordance with GAAP), as the Company believes these non-GAAP financial measures reflect an additional way of viewing aspects of the Company's business that, when viewed together with its GAAP financial results, provide a more complete understanding of factors and trends affecting its historical financial performance and future operating results, greater transparency of underlying trends and greater comparability of results across periods. In addition, management believes that these non-GAAP financial measures may enhance investors' ability to assess the Company's historical and future financial performance. These non-GAAP financial measures are not intended to be a substitute for the comparable GAAP financial measure and should be read only in conjunction with the Company's consolidated financial statements prepared in accordance with GAAP. Noncash MTM adjustments and unusual items may recur in future periods; however, the amount and frequency can vary significantly from period to period. The Company's net income attributable to common stockholders as determined in accordance with GAAP is reconciled to income adjusted for noncash MTM adjustments, including (i) the Company's derivative positions and (ii) the Company's equity investment in ProPetro Holding Corp.

PIONEER NATURAL RESOURCES COMPANY UNAUDITED SUPPLEMENTAL NON-GAAP FINANCIAL MEASURES (continued) (in millions)

Free cash flow ("FCF") is a non-GAAP financial measure. As used by the Company, FCF is defined as net cash provided by operating activities, adjusted for changes in operating assets and liabilities and acquisition transaction costs (excluding stock-based compensation), less capital expenditures. The Company believes this non-GAAP measure is a financial indicator of the Company's ability to internally fund acquisitions, debt maturities, dividends and share repurchases after capital expenditures.

Marketing derivatives. The Company's marketing derivatives reflect two long-term marketing contracts that were entered in October 2019. Under the contract terms, beginning on January 1, 2021, the Company agreed to purchase and simultaneously sell 50 thousand barrels of oil per day at an oil terminal in Midland, Texas for a six-year term that ends on December 31, 2026. The price the Company pays to purchase the oil volumes under the purchase contract is based on a Midland WTI price and the price the Company receives for the oil volumes sold is a weighted average sales price that a non-affiliated counterparty receives for selling oil through their Gulf Coast storage and export facility at prices that are highly correlated with Brent oil prices during the same month of the purchase.
