• Full year 2023 total production averaged 715 thousand barrels of oil equivalent per day (MBOEPD), above the top end of both original and most recently updated 2023 guidance

• Full year 2023 drilling, completions, facilities and water infrastructure capital expenditures totaled $4.4 billion, below the bottom end of original 2023 guidance and near the bottom end of the most recently updated 2023 guidance

• Generated strong fourth quarter and full year 2023 free cash flow¹ of $1.2 billion and $4.1 billion, respectively

• Generated a return on capital employed² of 19% during 2023

• Declared a quarterly base-plus-variable dividend of $2.56 per share to be paid on March 22, 2024

Financial Highlights

Pioneer maintains a strong balance sheet, with net debt of $4.6 billion as of December 31, 2023. The Company had $2.2 billion of liquidity, comprised of $240 million of cash on hand and a $2.0 billion unsecured credit facility (undrawn) as of December 31, 2023.

During the fourth quarter, the Company's total capital expenditures³ totaled $1.1 billion. For the full year 2023, the Company's total capital expenditures³ totaled $4.6 billion.

Cash flow from operating activities during the fourth quarter and full year 2023 was $2.3 billion and $8.4 billion, respectively, leading to free cash flow¹ of $1.2 billion for the fourth quarter and $4.1 billion for the full year 2023.

For the first quarter of 2024, the Company's Board of Directors has declared a quarterly base-plus-variable dividend of $2.56 per share, comprised of a $1.25 base dividend and $1.31 variable dividend. This represents a total annualized dividend yield of 4.4%⁴. Pursuant to the merger agreement with Exxon Mobil Corporation ("ExxonMobil"), any quarterly dividends declared subsequent to the first quarter of 2024 are expected to be comprised solely of the $1.25 per share base dividend component⁵.

Fourth Quarter Financial Results

For the fourth quarter of 2023, the average realized price for oil was $78.47 per barrel. The average realized price for natural gas liquids (NGLs) was $23.25 per barrel, and the average realized price for gas was $2.35 per thousand cubic feet. These prices exclude the effects of derivatives.

Production costs, including taxes, averaged $10.54 per barrel of oil equivalent (BOE). Depreciation, depletion and amortization expense averaged $11.30 per BOE. Exploration and abandonment expense was $24 million. General and administrative expense was $202 million, including ExxonMobil merger-related costs of $102 million. Interest expense was $39 million. The net cash flow impact related to purchases and sales of oil and gas, including firm transportation, was a loss of $105 million. Other expense was $37 million. Current income tax provision was $183 million. The Company's effective tax rate was 22% for the quarter.

Operations Update

Pioneer continued to deliver strong operational performance in the Midland Basin, which led to the Company placing 482 horizontal wells on production during 2023, including 135 horizontal wells placed on production during the fourth quarter.

More than 125 wells with lateral lengths of 15,000 feet or greater were placed on production in 2023. These longer-lateral wells have contributed to Pioneer’s strong results. The development of wells with lateral lengths in excess of 15,000 feet provides significant capital savings on a per foot basis and is expected to generate an internal rate of return (IRR) that is on average 35% higher than a comparable 10,000-foot lateral well. In total, the Company has over 1,000 future locations with 15,000-foot lateral lengths in its drilling inventory.

During the fourth quarter, Pioneer benefited from its utilization of three simulfrac fleets and two localized sand mines. During 2023, the Company transitioned 100% of its completions fleets to either electric or dual-fuel powered and progressed its electrification efforts through the successful execution of drilling and completions trials utilizing grid-supplied electricity. Additionally, Pioneer plans to add a fourth simulfrac fleet in the first half of 2024, providing further efficiencies and cost benefits.

During 2023, Pioneer’s operational teams delivered a sixth consecutive year of improved drilling and completions efficiencies. Extended laterals, utilization of simulfrac fleets and the transition of completions fleets from diesel-only fuel are a few examples of the many continuous improvement efforts that the Company's operational teams continue to progress.

2024 Outlook

The Company expects its 2024 capital budget³ to range between $4.2 billion to $4.6 billion. Pioneer expects its capital program to be funded from 2024 cash flow from operating activities.

Pioneer expects 2024 oil production of 384 to 392 MBOPD and total production of 750 to 766 MBOEPD.

Proved Reserves

The Company added proved reserves totaling 397 million barrels of oil equivalent (MMBOE) during 2023, excluding acquisitions and price revisions. These proved reserve additions equate to a drillbit reserve replacement ratio of 150% when compared to Pioneer's full year 2023 production of 264 MMBOE, including field fuel. The drillbit finding and development (F&D) cost was $11.48 per BOE in 2023, with a drillbit proved developed F&D cost of $11.01 per BOE.

As of December 31, 2023, the Company's total proved reserves were estimated at 2,471 MMBOE, of which 90% are proved developed.

Environmental, Social & Governance (ESG)

Pioneer views sustainability as a multidisciplinary effort 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.

Earnings Conference Call

Due to the pending merger with ExxonMobil, Pioneer will not host a conference call or webcast to discuss its results for the fourth quarter and year ended December 31, 2023.

"Drillbit finding and development cost per BOE," or "drillbit F&D cost per BOE," means the summation of exploration and development costs incurred divided by the summation of annual proved reserves, on a BOE basis, attributable to discoveries, extensions and revisions of previous estimates. Revisions of previous estimates exclude price revisions. Consistent with industry practice, future capital costs to develop proved undeveloped reserves are not included in costs incurred.

"Drillbit proved developed finding and development cost per BOE," or "drillbit proved developed F&D cost per BOE," means the summation of exploration and development costs incurred (excluding asset retirement obligations) divided by the summation of annual proved reserves, on a BOE basis, attributable to proved developed reserve additions, including (i) discoveries and extensions placed on production during 2023, (ii) transfers from proved undeveloped reserves at year-end 2022 and (iii) technical revisions of previous estimates for proved developed reserves during 2023. Revisions of previous estimates exclude price revisions.

"Drillbit reserve replacement" is the summation of annual proved reserves, on a BOE basis, attributable to discoveries, extensions and revisions of previous estimates divided by annual production of oil, NGLs and gas, on a BOE basis. Revisions of previous estimates exclude price revisions.

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 certain after-tax ExxonMobil merger-related costs, less capital expenditures³. See the supplemental schedules for a reconciliation of fourth quarter and full year 2023 free cash flow to the comparable GAAP number.

Footnote 2: Return on capital employed (ROCE) is a non-GAAP financial measure. As used by the Company, ROCE is net income adjusted for tax-effected noncash mark-to-market (MTM) adjustments, unusual items and interest expense divided by the summation of average total equity (adjusted for tax-effected noncash MTM adjustments, unusual items and interest expense) and average net debt. See reconciliation to comparable GAAP number in supplemental schedules.

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

Footnote 4: Calculated by dividing the Company's annualized first quarter 2024 total dividend per share by the Company's closing share price on February 16, 2024.

Footnote 5: Future dividends 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 maintains to fund future capital expenditures or other needs, and other factors that the Board of Directors deems relevant, including restrictions set forth in the merger agreement with ExxonMobil. The Company can provide no assurance that dividends will be authorized or declared in the future or the amount of any future dividends.

Note: Estimates of future results 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 United States Securities and Exchange Commission 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
SUPPLEMENTARY EARNINGS PER SHARE INFORMATION
(in millions, except per share data)

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 accepted 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 shareholders, (ii) less participating share-based earnings (iii) divided by weighted average basic shares outstanding. The Company's diluted net income per share attributable to common shareholders is computed as (i) basic net income attributable to common shareholders, (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 shareholders, securities or other contracts to issue common shares would be dilutive to loss per share; therefore, conversion into common shares is assumed not to occur.

The Company's net income attributable to common shareholders is reconciled to basic and diluted net income attributable to common shareholders as follows:

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 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 or net cash provided by operating activities, as defined by GAAP.

SUPPLEMENTAL NON-GAAP FINANCIAL MEASURES (continued)
(in millions, except per share data)

Adjusted income attributable to common shareholders 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 shareholders (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.

Return on Capital Employed ("ROCE") is a non-GAAP financial measure. As used by the Company, ROCE is net income adjusted for tax-effected noncash MTM adjustments, unusual items and interest expense divided by the summation of average total equity (adjusted for tax effected noncash MTM adjustments, unusual items and interest expense) and average net debt. The Company believes ROCE is a good indicator of long-term performance, both absolute and relative to the Company's peers. ROCE is a measure of the profitability of the Company’s capital employed in its business compared with that of its peers.

Derivative Positions as of December 31, 2023

Marketing derivatives. The Company's marketing derivatives reflect long-term marketing contracts whereby the Company agreed to purchase and simultaneously sell, at an oil terminal in Midland, Texas, (i) 50 thousand barrels of oil per day beginning January 1, 2021 and ending December 31, 2026, (ii) 40 thousand barrels of oil per day beginning May 1, 2022 and ending April 30, 2027 and (iii) 30 thousand barrels of oil per day beginning August 1, 2022 and ending July 31, 2027.

The price the Company pays to purchase the oil volumes under the purchase contracts 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 a Gulf Coast storage and export facility at prices that are highly correlated with Brent oil prices during the same month of the purchase. Based on the form of the long-term marketing contracts, the Company accounts for the contracts as derivative instruments not designated as hedges.

Conversion option derivatives. In May 2020, the Company issued $1.3 billion principal amount of convertible senior notes due 2025 (the "Convertible Notes"). Certain holders of the Convertible Notes have exercised their conversion options per the terms of the notes indenture. The Company elected to settle the conversions in cash, with settlement occurring 25 trading days from the notice of conversion (the "Settlement Period"). The Company's election to settle an exercised conversion option in cash results in a forward contract during the Settlement Period that is accounted for as a derivative instrument not designated as a hedge. As of December 31, 2023, $28 million of the principal amount of the Company's Convertible Notes remained in the Settlement Period.
