•"Bbl" means a standard barrel containing 42 United States gallons.

•"Bcf" means one billion cubic feet and is a measure of gas volume.

•"BOE" means a barrel of oil equivalent and is a standard convention used to express oil and gas volumes on a comparable oil equivalent basis. Gas equivalents are determined under the relative energy content method by using the ratio of six thousand cubic feet of gas to one Bbl of oil or natural gas liquid.

•"BOEPD" means BOE per day.

•"MMBOPD" means one million barrels of oil per day.

•"Btu" means British thermal unit, which is a measure of the amount of energy required to raise the temperature of one pound of water one degree Fahrenheit.

•"MBbl" means one thousand Bbls.

•"MBOE" means one thousand BOEs.

•"Mcf" means one thousand cubic feet and is a measure of gas volume.

•"MMBbl" means one million Bbls.

•"MMBOE" means one million BOEs.

•"MMBtu" means one million Btus.

•"MMcf" means one million cubic feet.

Indices.

•"Brent" means Brent oil price, a major trading classification of light sweet oil that serves as a benchmark price for oil worldwide.

•"WAHA" is a benchmark pricing hub for West Texas gas.

•"WTI" means West Texas Intermediate, a light sweet blend of oil produced from fields in western Texas and is a grade of oil used as a benchmark in oil pricing.

General terms and conventions.

•"DD&A" means depletion, depreciation and amortization.

•"ESG" means environmental, social and governance.

•"Field fuel" means gas consumed to operate field equipment (primarily compressors) prior to the gas being delivered to a sales point.

•"GAAP" means accounting principles generally accepted in the United States of America.

•"GHG" means greenhouse gases.

•"LNG" means liquefied natural gas.

•"NGLs" means natural gas liquids, which are the heavier hydrocarbon liquids that are separated from the gas stream; such liquids include ethane, propane, isobutane, normal butane and natural gasoline.

•"NYMEX" means the New York Mercantile Exchange.

•"NYSE" means the New York Stock Exchange.

•"OPEC" means the Organization of Petroleum Exporting Countries.

•"Pioneer" or the "Company" means Pioneer Natural Resources Company and its subsidiaries.

•"Proved developed reserves" means reserves that can be expected to be recovered through existing wells with existing equipment and operating methods or in which the cost of the required equipment is relatively minor compared to the cost of a new well.

•"Proved reserves" means those quantities of oil and gas, which, by analysis of geosciences and engineering data, can be estimated with reasonable certainty to be economically producible – from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations – prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time.

3

(i) The area of the reservoir considered as proved includes: (A) The area identified by drilling and limited by fluid contacts, if any, and (B) Adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged to be continuous with it and to contain economically producible oil or gas on the basis of available geoscience and engineering data.

(ii) In the absence of data on fluid contacts, proved quantities in a reservoir are limited by the lowest known hydrocarbons as seen in a well penetration unless geoscience, engineering or performance data and reliable technology establishes a lower contact with reasonable certainty.

(iii) Where direct observation from well penetrations has defined a highest known oil elevation and the potential exists for an associated gas cap, proved oil reserves may be assigned in the structurally higher portions of the reservoir only if geoscience, engineering or performance data and reliable technology establish the higher contact with reasonable certainty.

(iv) Reserves which can be produced economically through application of improved recovery techniques (including, but not limited to, fluid injection) are included in the proved classification when: (A) Successful testing by a pilot project in an area of the reservoir with properties no more favorable than in the reservoir as a whole, the operation of an installed program in the reservoir or an analogous reservoir, or other evidence using reliable technology establishes the reasonable certainty of the engineering analysis on which the project or program was based; and (B) The project has been approved for development by all necessary parties and entities, including governmental entities.

(v) Existing economic conditions include prices and costs at which economic producibility from a reservoir is to be determined. The price shall be the average during the 12-month period prior to the ending date of the period covered by the report, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month within such period, unless prices are defined by contractual arrangements, excluding escalations based upon future conditions.

•"Proved undeveloped reserves" means reserves that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion.

(i) Reserves on undrilled acreage shall be limited to those directly offsetting development spacing areas that are reasonably certain of production when drilled, unless evidence using reliable technology exists that establishes reasonable certainty of economic producibility at greater distances.

(ii) Undrilled locations can be classified as having proved undeveloped reserves only if a development plan has been adopted indicating that they are scheduled to be drilled within five years, unless the specific circumstances, justify a longer time.

(iii) Under no circumstances shall estimates for proved undeveloped reserves be attributable to any acreage for which an application of fluid injection or other improved recovery technique is contemplated, unless such techniques have been proved effective by actual projects in the same reservoir or an analogous reservoir, or by other evidence using reliable technology establishing reasonable certainty.

•"SEC" means the United States Securities and Exchange Commission.

•"Standardized Measure" means the after-tax present value of estimated future net cash flows of proved reserves, determined in accordance with the rules and regulations of the SEC, using prices and costs employed in the determination of proved reserves and a 10 percent discount rate.

•"U.S." means United States.

•With respect to information on the working interest in wells, drilling locations and acreage, "net" wells, drilling locations and acres are determined by multiplying "gross" wells, drilling locations and acres by the Company's working interest in such wells, drilling locations or acres. Unless otherwise specified, wells, drilling locations and acreage statistics quoted herein represent gross wells, drilling locations or acres.

•"WASP" means weighted average sales price.

•All currency amounts are expressed in U.S. dollars.

CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS

This information in this Quarterly Report on Form 10-Q (this "Report") contains forward-looking statements that involve risks and uncertainties. When used in this document, the words "believes," "plans," "expects," "anticipates," "forecasts," "models," "intends," "continue," "may," "will," "could," "should," "future," "potential," "estimate," or the negative of such terms and similar expressions as they relate to the Company are intended to identify forward-looking statements, which are generally not historical in nature. The forward-looking statements are based on the Company's current expectations, assumptions, estimates and projections about the Company and the industry in which the Company operates. Although the Company believes that the expectations and assumptions reflected in the forward-looking statements are reasonable as and when made, they involve risks and uncertainties that are difficult to predict and, in many cases, beyond the Company's control. In addition, the Company may be subject to currently unforeseen risks that may have a materially adverse effect on it.

These risks and uncertainties include, among other things, volatility of commodity prices; product supply and demand; the impact of armed conflict (including the war in Ukraine) and political instability on economic activity and oil and gas supply and demand; competition; the ability to obtain drilling, 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 potential changes to tax laws; 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, including the potential impact of cost increases due to inflation and supply chain disruptions, and results of development and operating activities; the impact of a widespread outbreak of an illness, such as the COVID-19 pandemic, on global and U.S. economic activity, oil and gas demand, and global and U.S. supply chains; the risk of new restrictions with respect to development activities, including potential changes to regulations resulting in limitations on the Company's ability to dispose of produced water; availability of equipment, services, resources and personnel required to perform the Company's development 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 Company's ability to achieve its emissions reductions, flaring and other ESG goals; access to and cost of capital; the financial strength of (i) counterparties to Pioneer's credit facility and derivative contracts, (ii) issuers of Pioneer's investment securities and (iii) purchasers of Pioneer's oil, NGL and gas production and downstream sales of purchased commodities; uncertainties about estimates of reserves, identification of drilling locations and the ability to add proved reserves in the future; the assumptions underlying forecasts, including forecasts of production, operating cash flow, well costs, capital expenditures, rates of return, expenses, and cash flow from downstream purchases and sales of oil and gas, net of firm transportation commitments; tax rates; quality of technical data; environmental and weather risks, including the possible impacts of climate change on the Company's operations and demand for its products; cybersecurity risks; the risks associated with the ownership and operation of the Company's water services business and acts of war or terrorism. 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. See "Part I, Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations," "Part 1, Item 3. Quantitative and Qualitative Disclosures About Market Risk" and "Part II, Item 1A. Risk Factors" in this Report and "Part I, Item 1. Business — Competition," "Part I, Item 1. Business —Regulation," "Part I, Item 1A. Risk Factors," "Part II, Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Part II, Item 7A. Quantitative and Qualitative Disclosures About Market Risk" in the Company's Annual Report on Form 10-K for the year ended December 31, 2022 for a description of various factors that could materially affect the ability of Pioneer to achieve the anticipated results described in the forward-looking statements. Readers are cautioned not to place undue reliance on forward-looking statements, which speak only as of the date hereof. Pioneer undertakes no duty to publicly update these statements except as required by law.

PIONEER NATURAL RESOURCES COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

March 31, 2023

(Unaudited)

NOTE 1. Organization and Nature of Operations

Pioneer is a Delaware corporation whose common stock is listed and traded on the NYSE. The Company is a large independent oil and gas exploration and production company that explores for, develops and produces oil, NGLs and gas in the Midland Basin in West Texas.

NOTE 2. Basis of Presentation

Presentation. In the opinion of management, the unaudited interim consolidated financial statements of the Company as of March 31, 2023 and for the three months ended March 31, 2023 and 2022 include all adjustments and accruals, consisting only of normal, recurring adjustments and accruals necessary for a fair presentation of the results for the interim periods in conformity with GAAP. The operating results for the three months ended March 31, 2023 are not necessarily indicative of results for a full year.

Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted in accordance with the rules and regulations of the SEC. These unaudited interim consolidated financial statements should be read together with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2022.

Use of estimates in the preparation of financial statements. Preparation of the Company's consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from the estimates and assumptions utilized.

NOTE 3. Acquisition, Divestiture and Nonmonetary Activities

Acquisitions. The Company regularly seeks to acquire or trade for acreage that complements its operations, provides exploration and development opportunities, increases the lateral length of future horizontal wells and provides superior returns on investment.

Divestitures. The Company regularly reviews its asset base to identify nonstrategic assets, the disposition of which would increase capital resources available for other activities, create organizational and operational efficiencies and further the Company's objective of maintaining a strong balance sheet to ensure financial flexibility.

•During the three months ended March 31, 2022, the Company divested certain undeveloped acreage and producing wells in the Midland Basin for (i) cash proceeds of $85 million and (ii) ownership interests in certain Midland Basin undeveloped acreage and producing wells valued at $8 million. The Company recorded a gain on these sales of $41 million, which is reflected in net gain on disposition of assets in the consolidated statements of operations.

•In February 2022, the Company completed the sale of its equity interest in certain gas gathering and processing systems in northern Martin County for cash proceeds of $125 million (the "Martin County Gas Processing Divestiture"). The sale was treated as a recovery of investment from a partial sale of proved property resulting in no gain or loss being recognized.

Nonmonetary transactions. During the three months ended March 31, 2023, the Company's nonmonetary transactions included exchanges of both proved and unproved oil and gas properties in the Midland Basin with unaffiliated third parties. Certain of these transactions were accounted for at fair value, resulting in the Company recording a gain of $24 million to net gain on disposition of assets in the consolidated statements of operations and $162 million of noncash investing activities.

NOTE 4. Fair Value Measurements

The Company determines fair value based on the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements are based upon inputs that market participants use in pricing an asset or liability, which are characterized according to a hierarchy that prioritizes those inputs based on the degree to which they are observable. Observable inputs represent market data obtained from independent sources, whereas unobservable inputs reflect a company's own market assumptions, which are used if observable inputs are not reasonably available without undue cost and effort. The fair value input hierarchy level to which an

11

PIONEER NATURAL RESOURCES COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

March 31, 2023

(Unaudited)

asset or liability measurement in its entirety falls is determined based on the lowest level input that is significant to the measurement in its entirety.

The three input levels of the fair value hierarchy are as follows:

•Level 1 – quoted prices for identical assets or liabilities in active markets.

•Level 2 – quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e.g. interest rates) and inputs derived principally from or corroborated by observable market data by correlation or other means.

•Level 3 – unobservable inputs for the asset or liability, typically reflecting management's estimate of assumptions that market participants would use in pricing the asset or liability. The fair values are therefore determined using model-based techniques, including discounted cash flow models.

Assets and liabilities measured at fair value on a recurring basis. Assets and liabilities measured at fair value on a recurring basis are as follows:

Investment in affiliate. The Company elected the fair value option for measuring its equity method investment in ProPetro Holding Corp. ("ProPetro"). The fair value of the Company's investment in ProPetro common stock is determined using Level 1 inputs based on observable prices on a major exchange. The Company recorded a noncash loss of $53 million and a noncash gain of $96 million to net interest and other income (loss) in the consolidated statements of operations during the three months ended March 31, 2023 and 2022, respectively, representing the change in fair value of the Company's investment in ProPetro. See Note 11 for additional information.

Deferred compensation plan assets. The Company's deferred compensation plan assets include investments in equity and mutual fund securities that are actively traded on major exchanges. The fair value of these investments is determined using Level 1 inputs based on observable prices on major exchanges. The Company recorded losses of $1 million and $3 million to net interest and other income (loss) in the consolidated statements of operations during the three months ended March 31, 2023 and 2022, respectively, representing the change in fair value of deferred compensation plan assets.

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 exercised their conversion option during the three months ended March 31, 2023 and December 31, 2022. 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. The change in fair value of the conversion option derivatives during the Settlement Period is primarily determined based on Level 2 inputs related to the daily volumetric weighted average prices of the Company's common stock during the Settlement Period. See Note 5 and Note 7 for additional information.

Commodity price derivatives. The asset and liability measurements for the Company's commodity price derivative contracts are determined using Level 2 inputs. The Company utilizes discounted cash flow and option-pricing models for valuing its commodity price derivatives.

The values attributable to the Company's commodity price derivatives were determined based on inputs that include (i) the contracted notional volumes, (ii) independent active market price quotes, (iii) the applicable estimated credit-adjusted risk-free rate yield curve and (iv) the implied rate of volatility inherent in the swap contracts, which is based on active and independent market-quoted volatility factors. The Company's commodity price derivatives represent oil basis swap contracts as of March 31, 2023 and December 31, 2022. Commodity price derivative assets and liabilities recorded in the consolidated balance sheets were less than $1 million as of March 31, 2023 and December 31, 2022. See Note 5 for additional information.

Marketing derivatives. The Company's marketing derivatives reflect long-term marketing contracts whereby the Company agreed to purchase and simultaneously sell barrels of oil at an oil terminal in Midland, Texas. The price the Company pays to purchase the oil volumes under the purchase contract is based on a Midland oil price and the price the Company receives for the oil volumes sold is the WASP that the 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. The asset and liability measurements for the long-term marketing contracts are determined using both Level 2 and 3 inputs. The Company utilizes a discounted cash flow model for valuing the marketing derivatives.

The values attributable to the Company's marketing derivatives that are determined based on Level 2 inputs include (i) the contracted notional volumes, (ii) independent active market price quotes, (iii) the applicable estimated credit-adjusted risk-free rate yield curve and (iv) stated contractual rates. The Level 3 inputs attributable to the Company's marketing derivatives include the historical monthly differential between Brent oil prices and the corresponding WASP of the counterparty to the marketing derivatives ("WASP Differential Deduction") and, to a lesser extent, an estimated annual cost inflation rate. The average WASP Differential Deduction used in the fair value determination as of March 31, 2023 and December 31, 2022 was $1.81 per barrel and $1.67 per barrel, respectively. The WASP Differential Deduction and the estimated annual cost inflation rate reflects management's best estimate of future results utilizing historical performance, but these estimates are not observable inputs by a market participant and contain a high degree of uncertainty. The Company experiences mark-to-market fluctuations in the fair value of its marketing derivatives based on changes in the WASP Differential Deduction if it deviates from historical levels. For example, a 10 percent increase or decrease in the WASP Differential Deduction would impact the fair value of the Company's marketing derivatives recorded by $29 million as of March 31, 2023. See Note 5 for additional information.

Short-term investment. In October 2021, the Company acquired 960 thousand shares of Laredo Petroleum, Inc. ("Laredo") as partial consideration for its divestiture of certain acreage in western Glasscock County to Laredo. During the three months ended March 31, 2022, the Company sold the 960 thousand shares of Laredo common stock held by the Company and recorded a gain of $18 million to net interest and other income (loss) in the consolidated statements of operations. The shares were treated as an investment in equity securities measured at fair value. The fair value of the Company's investment in Laredo common stock was determined using Level 1 inputs based on observable prices on a major exchange.

Assets and liabilities measured at fair value on a nonrecurring basis. Certain assets and liabilities are measured at fair value on a nonrecurring basis. These assets and liabilities are not measured at fair value on an ongoing basis, but are subject to fair value adjustments in certain circumstances. These assets and liabilities can include inventories, proved and unproved oil and gas properties, assets acquired and liabilities assumed in business combinations or through nonmonetary transactions, goodwill and other long-lived assets that are written down to fair value when they are determined to be impaired or held for sale.

Nonmonetary transactions. Oil and gas properties acquired in nonmonetary transactions that have commercial substance are valued based on income and market based approaches utilizing Level 3 inputs, including internally generated development and production profiles and price and cost assumptions. As a result of these valuations, the Company recorded a gain of $24 million to net gain on disposition of assets in the consolidated statements of operations during the three months ended March 31, 2023.

Other long-lived assets. The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If such assets are considered to be impaired, the impairment charge is measured as the amount by which the carrying amount of the asset exceeds its estimated fair value determined using either a discounted future cash flow model or another appropriate fair value method. As a result of the Company's impairment assessments of other long-lived assets during the three months ended March 31, 2023, the Company recorded $11 million of noncash impairment charges to other expense in the consolidated statements of operations. See Note 13 for additional information.

Financial instruments not carried at fair value. Carrying values and fair values of financial instruments that are not carried at fair value in the consolidated balance sheets are as follows:

	As of March 31, 2023				As of December 31, 2022
	Carrying Value		Fair Value		Carrying Value		Fair Value

______________________

(a)Fair value approximates carrying value due to the short-term nature of the instruments.

(b)Fair value is determined using Level 2 inputs. The Company's senior notes are quoted, but not actively traded on major exchanges; therefore, fair value is based on periodic values as quoted on major exchanges. See Note 7 for additional information.

The Company has other financial instruments consisting primarily of receivables, payables and other current assets and liabilities that approximate fair value due to the nature of the instrument and their relatively short maturities. Non-financial assets and liabilities initially measured at fair value include assets acquired and liabilities assumed in business combinations, goodwill and asset retirement obligations.

NOTE 5. Derivative Financial Instruments

The Company's derivatives are accounted for as non-hedge derivatives and all changes in the fair values of its derivative contracts are recognized as gains or losses in the earnings of the periods in which they occur.

The Company uses credit and other financial criteria to evaluate the credit standing of, and to select, counterparties to its derivative instruments. Although the Company does not obtain collateral or otherwise secure the fair value of its derivative instruments, associated credit risk is mitigated by the Company's credit risk policies and procedures.

Commodity derivatives. As of March 31, 2023, the Company has outstanding oil derivative contracts for three thousand Bbls per day of Brent/WTI basis swaps for January 2024 through December 2024. The basis swap contracts fix the basis differential between the WTI index price (the price at which the Company buys Midland Basin oil for transport to the Gulf Coast) and the Brent index price (the price at which a portion of the Midland Basin purchased oil is sold in the Gulf Coast market) at a weighted average differential of $4.33 in order to reduce the Company's basis risk.

Marketing derivatives. The Company uses marketing derivatives to diversify its oil pricing to Gulf Coast and international markets. As of March 31, 2023, the Company's marketing derivatives reflect long-term marketing contracts with Occidental Energy Marketing, Inc. ("Oxy") 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. Based on the form of the long-term marketing contracts, the Company accounts for the contracts as derivative instruments not designated as hedges. See Note 4 for additional information.

Conversion option derivatives. The Company's conversion option derivatives represent the change in the cash settlement obligation that occurs during the Settlement Period related to conversion options exercised by certain holders of the Convertible Notes. As of March 31, 2023 and December 31, 2022, $65 million and $29 million, respectively, of the principal amount of the Convertible Notes remained in the Settlement Period. See Note 4 and Note 7 for additional information.

Credit facility. The Company maintains a revolving corporate credit facility (the "Credit Facility") with a syndicate of financial institutions and has aggregate loan commitments of $2.0 billion. The Credit Facility has a maturity date of January 12, 2026. As of March 31, 2023, the Company had no outstanding borrowings under the Credit Facility. The Credit Facility requires the maintenance of a ratio of total debt to book capitalization, subject to certain adjustments, not to exceed 0.65 to 1.0. As of March 31, 2023, the Company was in compliance with its debt covenants.

Senior notes. In March 2023, the Company issued $1.1 billion of 5.100% senior notes that will mature March 29, 2026 (the "March 2023 Senior Notes Offering"). The Company received proceeds, net of $7 million of issuance costs and discounts, of $1.1 billion. Interest on the notes is payable on March 29 and September 29 of each year.

The Company's 0.550% senior notes, with a debt principal balance of $750 million, will mature in May 2023. The 0.550% senior notes are recorded in the current portion of long-term debt in the consolidated balance sheets as of March 31, 2023.

The Company's senior notes are general unsecured obligations ranking equally in right of payment with all other senior unsecured indebtedness of the Company and are senior in right of payment to all existing and future subordinated indebtedness of the Company. The Company is a holding company that conducts all of its operations through subsidiaries; consequently, the senior notes are structurally subordinated to all obligations of its subsidiaries. Interest on the Company's senior notes is payable semiannually.

Convertible senior notes. The Convertible Notes bear a fixed interest rate of 0.250% per year, with interest payable on May 15 and November 15 of each year. The Convertible Notes will mature on May 15, 2025, unless earlier redeemed, repurchased or converted. The Convertible Notes are unsecured obligations ranking equally in right of payment with all other senior unsecured indebtedness of the Company.

The Convertible Notes are convertible into shares of the Company's common stock at an adjusted conversion rate of 10.5356 shares of the Company's common stock per $1,000 principal amount of the Convertible Notes (subject to further adjustment pursuant to the terms of the notes indenture, the "Conversion Rate"), which represents an adjusted conversion price of $94.92 per share (subject to adjustment pursuant to the terms of the notes indenture, the "Conversion Price"). Upon conversion, the Convertible Notes will be settled in cash, shares of the Company's common stock or a combination thereof, at the Company's election.

Holders of the Convertible Notes may convert their notes at their option prior to February 15, 2025 under the following circumstances:

•during the quarter following any quarter during which the last reported sales price of the Company's common stock for at least 20 of the last 30 consecutive trading days of such quarter exceeds 130 percent of the Conversion Price;

•during the five-business day period following any five consecutive trading day period when the trading price of the Convertible Notes is less than 98 percent of the product of the last reported sales price of the Company's common stock and the Conversion Rate;

•upon notice of redemption by the Company; or

•upon the occurrence of specified corporate events, including certain consolidations or mergers.

On or after February 15, 2025, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their notes at any time. The Company may not redeem the Convertible Notes prior to May 20, 2023, and after such date, may redeem the Convertible Notes only if the last reported sale price of the Company's common stock has been at least 130 percent of the Conversion Price for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which the Company provides the notice of redemption. The redemption price is equal to 100 percent of the principal amount of the Convertible Notes to be redeemed, plus accrued and unpaid interest.

In connection with the issuance of the Convertible Notes, the Company entered into privately negotiated capped call transactions with certain financial institution counterparties (the "Capped Call"), the purpose of which was to reduce the potential dilution to the Company's common stock upon conversion of the Convertible Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of such converted notes, with such reduction and offset subject to a capped price. The Capped Call transactions have an adjusted strike price of $94.92 per share of common stock and an adjusted capped price of $135.07 per share of common stock. The net cost of $113 million incurred to purchase the Capped Call transactions was recorded as a reduction to additional paid-in capital in the consolidated balance sheets.

As of March 31, 2023, the Convertible Notes have unamortized issuance costs of $7 million. The effective annual interest rate on the Convertible Notes is 0.6 percent.

Interest expense recognized on the Convertible Notes is as follows:

As of March 31, 2023, there was $107 million of unrecognized stock-based compensation expense related to unvested stock-based compensation awards of which $15 million is attributable to Liability Awards. The unrecognized compensation expense will be recognized on a straight-line basis over the remaining requisite service periods of the awards, which is a period of less than three years on a weighted average basis. Performance Awards granted to the Company’s officers in 2023 will vest upon the achievement of certain financial performance targets over a three year period. Expense for these awards is estimated based upon the achievement of the performance targets and will be reassessed periodically. The cumulative impact of any change in estimate will be reflected in the period of the change.

NOTE 10. Commitments and Contingencies

Indemnifications. The Company has agreed to indemnify its directors and certain of its officers, employees and agents with respect to claims and damages arising from acts or omissions taken in such capacity, as well as with respect to certain litigation.

Legal actions. The Company is party to various proceedings and claims incidental to its business. While many of these matters involve inherent uncertainty, the Company believes that the amount of the liability, if any, ultimately incurred with respect to these proceedings and claims will not have a material adverse effect on the Company's consolidated financial position as a whole or on its liquidity, capital resources or future annual results of operations. The Company records reserves for contingencies when information available indicates that a loss is probable and the amount of the loss can be reasonably estimated. Significant judgement is required in making these estimates and the Company's final liabilities may ultimately be materially different.

Environmental. Environmental expenditures that relate to an existing condition caused by past operations and that have no future economic benefits are expensed. Environmental expenditures that extend the life of the related property or mitigate or prevent future environmental contamination are capitalized. Liabilities for expenditures that will not qualify for capitalization are recorded when environmental assessment and/or remediation is probable and the costs can be reasonably estimated. Such liabilities are undiscounted unless the timing of cash payments for the liability is fixed or reliably determinable. Environmental liabilities normally involve estimates that are subject to revision until settlement or remediation occurs.

Obligations following divestitures. In connection with its divestiture transactions, the Company may retain certain liabilities and provide the purchaser certain indemnifications, subject to defined limitations, which may apply to identified pre-closing matters, including matters of litigation, environmental contingencies, royalties and income taxes. The Company does not recognize a liability if the fair value of the obligation is immaterial or the likelihood of making payments under these guarantees is remote.

NOTE 11. Related Party Transactions

In December 2018, the Company completed the sale of its pressure pumping assets to ProPetro in exchange for 16.6 million shares of ProPetro common stock and $110 million of cash. ProPetro is considered a related party as the shares received represent 14 percent of ProPetro's outstanding common stock. In addition to the sale of equipment and related facilities, the Company entered into a long-term agreement with ProPetro for it to provide pressure pumping and related services that ended on December 31, 2022. The Company continues to utilize ProPetro for pressure pumping and related services during 2023.

Phillip A. Gobe, a nonemployee member of the Company's Board of Directors (the "Board"), was appointed by the board of directors of ProPetro to serve as its Executive Chairman in October 2019 and Chief Executive Officer in March 2020, and served as Chief Executive Officer and Chairman of the board of directors of ProPetro through August 31, 2021, at which point he continued as ProPetro's Executive Chairman. In March 2022, Mr. Gobe transitioned to non-executive Chairman of the board of directors of ProPetro. Mark S. Berg, the Company's Executive Vice President, Corporate Operations, serves as a member of the ProPetro board of directors under the Company's right to designate a director to the board of directors of ProPetro so long as the Company owns five percent or more of ProPetro's outstanding common stock.

Based on the Company's ownership in ProPetro and representation on the ProPetro board of directors, ProPetro is considered an affiliate.

Transactions for ProPetro pressure pumping related services were capitalized in oil and gas properties or charged to other expense as incurred. ProPetro pressure pumping related service charges are as follows:

NOTE 12. Revenue Recognition

Disaggregated revenue from contracts with purchasers. Revenues on sales of oil, NGLs, gas and purchased oil and gas are recognized when control of the product is transferred to the purchaser and payment can be reasonably assured. Sales prices for oil, NGLs and gas are negotiated based on factors normally considered in the industry, such as an index or spot price, distance from the well to the pipeline or market, commodity quality and prevailing supply and demand conditions. Accordingly, the prices received by the Company for oil, NGLs and gas generally fluctuate similar to changes in the relevant market index prices.

Performance obligations and contract balances. The majority of the Company's product sale commitments are short-term in nature with a contract term of one year or less. The Company typically satisfies its performance obligations upon transfer of control as described above in Disaggregated revenue from contracts with purchasers and records the related revenue in the month production is delivered to the purchaser. Settlement statements for sales of oil, NGLs, gas and sales of purchased oil and gas may not be received for 30 to 60 days after the date the volumes are delivered, and as a result, the Company is required to estimate the amount of volumes delivered to the purchaser and the price that will be received for the sale of the product. The Company records the differences between estimates and the actual amounts received for product sales in the month that payment is received from the purchaser. As of March 31, 2023 and December 31, 2022, the accounts receivable balance representing amounts due or billable under the terms of contracts with purchasers is $1.3 billion and $1.8 billion, respectively.

NOTE 14. Income Taxes

Enactment of the Inflation Reduction Act of 2022. On August 16, 2022, President Biden signed into law the Inflation Reduction Act of 2022 (the "IRA"), which includes, among other things, a corporate alternative minimum tax (the "CAMT"). Under the CAMT, a 15 percent minimum tax will be imposed on certain adjusted financial statement income of "applicable corporations," which is effective for tax years beginning after December 31, 2022. The CAMT generally treats a corporation as an "applicable corporation" in any taxable year in which the "average annual adjusted financial statement income" of the corporation and certain of its subsidiaries and affiliates for a three-taxable-year period ending prior to such taxable year exceeds $1 billion. The Company will continue to monitor and assess any impacts of the IRA on the Company's current year tax provision or the Company's consolidated financial statements.

The IRA also establishes a one percent excise tax on stock repurchases made by publicly traded U.S. corporations. The excise tax is effective for any stock repurchases after December 31, 2022. During the three months ended March 31, 2023, the Company recorded $5 million to treasury stock and other noncurrent liabilities in the consolidated balance sheets related to the IRA excise tax payable on stock repurchases.

Income tax provision and effective tax rate are as follows:

	Three Months Ended March 31,
	2023			2022
	(in millions)
Current tax provision	$	(225)		$	(20)
Deferred tax provision	(110)			(532)
Income tax provision	$	(335)		$	(552)
Effective tax rate	22		%	22		%

The Company evaluates and updates its annual effective income tax rate on an interim basis based on current and forecasted earnings and tax laws. The mix and timing of the Company's actual earnings compared to annual projections can cause interim effective tax rate fluctuations. The Company's interim effective tax rate for the three months ended March 31, 2023 and 2022 differed from the U.S. statutory rate of 21 percent primarily due to forecasted state income taxes.

The Company files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. As of March 31, 2023, there are no proposed adjustments in any jurisdiction that would have a significant effect on the Company's future results of operations or financial position.

(a)Unvested Equity Awards represent participating securities because they participate in non-forfeitable dividends with the common equity owners of the Company. Participating share-based earnings represent the distributed and undistributed earnings of the Company attributable to the participating securities. Unvested Equity Awards do not participate in undistributed net losses as they are not contractually obligated to do so. The dilutive effect of the reallocation of participating share-based earnings to diluted net income attributable to common stockholders was negligible.

(b)Diluted weighted average common shares outstanding includes the dilutive effect had the Company's Convertible Notes been converted as of the beginning of the three months ended March 31, 2023 and 2022, respectively. If converted by the holder, the Company may settle in cash, shares of the Company's common stock or a combination thereof, at the Company's election. See Note 7 for additional information.

Stockholders' equity. The Company's return of capital strategies include payments of base and variable dividends and a stock repurchase program. The Board, at its sole discretion, may change its dividend practices and/or the Company's stock repurchase program based on the Company's outlook for commodity prices, liquidity, debt levels, capital resources, quarterly operating cash flows or other factors. Dividends declared by the Board and stock repurchased during the period are presented in the Company's consolidated statements of equity as dividends declared and purchases of treasury stock, respectively. Dividends paid and stock repurchased during the period are presented as cash used in financing activities in the Company's consolidated statements of cash flows. Dividends that are declared and have not been paid, if any, are included in other current liabilities in the consolidated balance sheets.

	(in millions)
Shares repurchased (a)	$	500	$	250

______________________

(a)During the three months ended March 31, 2023, 2.4 million shares were repurchased under the stock repurchase program, as compared to 1.1 million shares repurchased during the three months ended March 31, 2022. Expenditures for share repurchases during the three months ended March 31, 2023 exclude the one percent excise tax on all stock repurchases after December 31, 2022.

In April 2023, the Board authorized a new $4 billion common stock repurchase program to replace the aforementioned $4 billion common stock repurchase program, which had $1.9 billion remaining at the time it was replaced. As was the case with the aforementioned stock repurchase programs, the Company may repurchase shares in accordance with applicable securities laws or pursuant to a trading plan meeting the requirements of Rule 10b5-1 under the Securities Act of 1934, which would permit the Company to repurchase shares at times that may otherwise be prohibited under the Company's insider trading policy.

NOTE 16. Subsequent Events

Dividends. On April 26, 2023, the Board declared a quarterly base dividend of $1.25 per share and a quarterly variable dividend of $2.09 per share on the Company's outstanding common stock, payable June 21, 2023 to shareholders of record at the close of business on June 1, 2023.

ITEM 2.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS

OF OPERATIONS

Oil and Gas Industry Considerations

Demand for oil throughout the world remains volatile since improving from the COVID-19 pandemic in mid-2020. Worldwide oil inventories have consistently been lower due to limited capital investments directed towards developing incremental oil supplies over the past few years. Sanctions, import bans and price caps on Russian crude oil and petroleum products have been implemented by various countries in response to the war in Ukraine, further impacting global oil supply. In addition, the lingering impacts from the pandemic, combined with the Russia/Ukraine conflict, have resulted in global supply chain disruptions, which have led to significant cost inflation and the potential for a global recession. This uncertainty led OPEC to reduce its oil demand outlook, which led to multiple cuts to its production quotas. As a result of the current global supply and demand uncertainties, average NYMEX oil and NYMEX gas prices for the three months ended March 31, 2023 were $76.21 per Bbl and $3.44 per Mcf, respectively, as compared to $94.29 per Bbl and $4.96 per Mcf, respectively, for the same period in 2022.

Global oil price levels and inflationary pressures will ultimately depend on various factors that are beyond the Company's control, such as (i) the ability of OPEC and other oil producing nations to manage the global oil supply, (ii) the impact of sanctions and import bans on production from Russia, (iii) the timing and supply impact of any Iranian sanction relief on their ability to export oil, (iv) the global supply chain constraints associated with manufacturing and distribution delays, (v) oilfield service demand and cost inflation, (vi) political stability of oil consuming countries and (vii) increasing expectations that the world may be heading into a global recession. The Company continues to assess and monitor the impact of these factors and consequences on the Company and its operations.

Financial and Operating Performance

The Company's financial and operating performance for the three months ended March 31, 2023 included the following highlights:

•Net income attributable to common stockholders for the three months ended March 31, 2023 was $1.2 billion ($5.00 per diluted share), as compared to net income of $2.0 billion ($7.85 per diluted share) for the same period in 2022. The primary components of the decrease in earnings attributable to common stockholders include:

•a $764 million decrease in oil and gas revenues, primarily due to a 25 percent decrease in average realized commodity prices per BOE in 2023 due to the aforementioned instability in worldwide oil, NGL and gas demand, partially offset by a seven percent increase in daily sales volumes due to the Company's successful Spraberry/Wolfcamp horizontal drilling program;

•a $163 million decrease in net interest and other income primarily due to a decrease in the fair value of the Company's investment in affiliate; and

•a $119 million decrease in net sales of purchased commodities due to a decline in margins on the Company's downstream Gulf Coast refinery and export oil sales.

partially offset by:

•a $217 million decrease in income taxes, primarily due to the decrease in earnings in 2023 compared to 2022; and

•a $91 million decrease in derivative losses, primarily due to a reduction in the Company's commodity derivative positions.

•During the three months ended March 31, 2023, average daily sales volumes increased on a BOE basis by seven percent to 680,440 BOEPD, as compared to 637,756 BOEPD during the same period in 2022.

•Average oil and NGL prices per Bbl and average gas prices per Mcf decreased to $75.15, $27.30 and $3.79, respectively, during the three months ended March 31, 2023, as compared to $94.60, $41.37 and $4.81, respectively, for the same period in 2022.

•Net cash provided by operating activities decreased during the three months ended March 31, 2023 to $2.3 billion, as compared to $2.6 billion for the same period in 2022. The decrease in net cash provided by operating activities during the three months ended March 31, 2023, as compared to the same period in 2022, is primarily due to (i) the aforementioned decrease in oil and gas revenues and (ii) an increase in the current income tax provision, partially offset by a decrease in cash used in derivative activities.

•During the three months ended March 31, 2023, the Company declared a base and variable dividend of $1.10 per share and $4.48 per share, respectively, and paid dividends of $1.3 billion, as compared to a declared base and

26

PIONEER NATURAL RESOURCES COMPANY

variable dividend of $0.78 per share and $3.00 per share, respectively, and dividend payments of $1.1 billion during the same period in 2022.

•During the three months ended March 31, 2023, the Company repurchased 2.4 million shares for $500 million under the Company's stock repurchase program, as compared to repurchases of 1.1 million shares for $250 million during the same period in 2022.

•As of March 31, 2023 and December 31, 2022, the Company's net debt to book capitalization was 18 percent and 15 percent, respectively.

Second Quarter 2023 Outlook

Based on current estimates, the Company expects the following operating and financial results for the second quarter of 2023:

	Three Months Ending June 30, 2023
	Guidance
	($ in millions, except per BOE amounts)
Average daily production (MBOE)	674 - 702
Average daily oil production (MBbls)	357 - 372
Production costs per BOE	$11.00 - $12.50
DD&A per BOE	$10.50 - $12.00
Exploration and abandonments expense	$10 - $20
General and administrative expense	$78 - $88
Interest expense	$39 - $44
Other expense	$20 - $40
Cash flow impact from firm transportation (a)	$(70) - $(30)
Current income tax provision	$200 - $275
Effective tax rate	22% - 27%

_____________________

(a)The expected cash flow impact from firm transportation is primarily based on (i) the forecasted differential between Midland WTI oil prices and Brent oil prices less the costs to transport purchased oil from the areas of the Company's production to the Gulf Coast and (ii) oil price fluctuations between the time the Company purchases the oil from its areas of operation and when the oil is delivered and sold to Gulf Coast refineries or exported to international markets. To the extent that the Company's Gulf Coast sales of purchased oil does not cover the purchase price and associated firm transport costs, the Company's results of operations will reflect the negative cash flow impact attributable to the shortfall.

Operations and Drilling Highlights

Average daily oil, NGL and gas sales volumes are as follows:

	Three Months Ended March 31, 2023
Oil (Bbls)	361,316
NGLs (Bbls)	167,486
Gas (Mcf)	909,831
Total (BOE)	680,440

The Company's liquids production was 78 percent of total production, on a BOE basis, for the three months ended March 31, 2023.

As of March 31, 2023, the Company's drilling and completions program included operating 25 drilling rigs and seven frac fleets in the Midland Basin. The Company will continue to evaluate its drilling and completions program with future activity levels assessed regularly.

Pioneer is the largest acreage holder in the Spraberry/Wolfcamp field in the Midland Basin of West Texas. In the southern portion of the Spraberry/Wolfcamp field, the Company has a joint venture ("JV") with Sinochem Petroleum USA LLC, a U.S. subsidiary of the Sinochem Group. During the three months ended March 31, 2023, the Company successfully completed 114 horizontal wells in the non-JV portion of the Midland Basin and 14 horizontal wells in the JV portion of the Midland Basin. In the non-JV portion of the Midland Basin, 38 percent of the horizontal wells placed on production were Spraberry interval wells, 34 percent were Wolfcamp B interval wells and the remaining 28 percent were Wolfcamp A interval wells. In the southern JV portion of the Midland Basin, all of the wells placed on production were Wolfcamp A or B interval wells.

Results of Operations

Oil and gas revenues. The Company's oil and gas revenues are derived from sales of oil, NGL and gas production. Increases or decreases in the Company's revenues, profitability and future production are highly dependent on commodity prices. Prices are market driven and future prices will fluctuate due to supply and demand factors, availability of transportation, seasonality, geopolitical developments and economic factors, among other items.

PIONEER NATURAL RESOURCES COMPANY

Average daily BOE sales volumes increased for the three months ended March 31, 2023, as compared to the same period in 2022, primarily due to the Company's successful Spraberry/Wolfcamp horizontal drilling program.

The oil, NGL and gas prices reported by the Company are based on the market prices received for each commodity. Commodity prices for the three months ended March 31, 2023, as compared to the same period in 2022, decreased due to the aforementioned instability in worldwide oil, NGL and gas demand. The average prices are as follows:

	Three Months Ended March 31,
	2023		2022		Change
Oil price per Bbl	$	75.15	$	94.60	(21	%)
NGL price per Bbl	$	27.30	$	41.37	(34	%)
Gas price per Mcf	$	3.79	$	4.81	(21	%)
Price per BOE	$	51.69	$	68.48	(25	%)

Net effect from sales of purchased commodities. The Company enters into pipeline capacity commitments in order to secure available oil, NGL and gas transportation capacity from the Company's areas of production and to secure diesel supply from the Gulf Coast. The Company also enters into purchase commitments to secure sand supply for the Company's operations in the Midland Basin. The Company enters into purchase transactions with third parties and separate sale transactions with third parties to diversify a portion of the Company's oil and gas sales to (i) Gulf Coast refineries, (ii) Gulf Coast and West Coast gas markets and (iii) international oil markets, and to satisfy unused gas pipeline capacity commitments. The Company periodically sells diesel and sand to unaffiliated third parties in the Permian Basin if it has supply in excess of its operational needs. Revenues and expenses from these transactions are generally presented on a gross basis in sales of purchased commodities and purchased commodities expense in the accompanying consolidated statements of operations as the Company acts as a principal in the transaction by assuming both the risks and rewards of ownership, including credit risk, of the commodities purchased and the responsibility to deliver the commodities sold. In conjunction with the Company's downstream sales, the Company also enters into pipeline capacity and storage commitments in order to secure available oil and gas transportation capacity from the Company's areas of production to downstream sales points and storage capacity at downstream sales points. The transportation and storage costs associated with these transactions are included in purchased commodities expense.

The net effect from sales of purchased commodities is as follows:

	Three Months Ended March 31,

	(in millions)
Sales of purchased commodities	$	1,431	$	2,217	$	(786)
Purchased commodities expense	1,485		2,152		(667)
	$	(54)	$	65	$	(119)

The change in the net effect from sales of purchased commodities for the three months ended March 31, 2023, as compared to the same period in 2022, is primarily due to a decline in margins on the Company's downstream Gulf Coast refinery and export oil sales.

Firm transportation payments on excess pipeline capacity are included in other expense in the accompanying consolidated statements of operations. See Note 13 of Notes to Consolidated Financial Statements included in "Item 1. Financial Statements" for additional information.

The change in net interest and other income (loss) for the three months ended March 31, 2023, as compared to the same period in 2022, is primarily due to (i) changes in the fair value of the Company's investment in affiliate resulting in a noncash loss of $53 million in 2023, as compared to a noncash gain of $96 million in 2022 and (ii) a noncash gain on the Company's short-term investment in Laredo of $18 million in 2022.

Commodity price derivatives. The Company primarily utilizes derivative contracts to reduce the effect of price volatility on the commodities the Company produces and sells. As of March 31, 2023, the Company has outstanding oil derivative contracts for three thousand Bbls per day of Brent/WTI basis swaps for January 2024 through December 2024. The basis swap contracts fix the basis differential between the WTI index price (the price at which the Company buys Midland Basin oil for transport to the Gulf Coast) and the Brent index price (the price at which a portion of the Midland Basin purchased oil is sold in the Gulf Coast market) at a weighted average differential of $4.33.

Marketing derivatives. The Company uses marketing derivatives to diversify its oil pricing to Gulf Coast and international markets. As of March 31, 2023, 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 contract is based on a Midland WTI price and the price the Company receives for the oil volumes sold is the WASP 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. As of March 31, 2023, the Company's Convertible Notes have an outstanding principal balance of $870 million. Certain holders of the Convertible Notes exercised their conversion option during the three months ended March 31, 2023. Per the terms of the notes indenture, the Company elected to settle the conversions in cash at the end of 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. The Company's conversion option derivatives represent the change in the cash settlement obligation that occurs during the Settlement Period related to conversion options exercised by certain holders of the Company's Convertible Notes.

The Company's open derivative contracts are subject to market risk. See "Item 3. Quantitative and Qualitative Disclosures About Market Risk" and Note 4 and Note 5 of Notes to Consolidated Financial Statements included in "Item 1. Financial Statements" for additional information.

PIONEER NATURAL RESOURCES COMPANY

The net gain on disposition of assets for the three months ended March 31, 2023 is primarily due to nonmonetary transactions in which the Company exchanged both proved and unproved oil and gas properties in the Midland Basin with unaffiliated third parties. Certain of these transactions were accounted for at fair value, resulting in the Company recording a gain of $24 million.

The net gain on disposition of assets for three months ended March 31, 2022 is primarily due to the divestment of certain undeveloped acreage and producing wells in the Midland Basin for cash proceeds of $85 million, resulting in a gain on the divestiture of $41 million.

____________________

(a)Lease operating expense and workover costs represent the components of oil and gas production costs over which the Company has management control.

(b)Gathering, processing and transportation expense represents the costs to (i) gather, process, transport and fractionate the Company's gas and NGLs to a point of sale and, to a lesser extent, (ii) gather and transport certain of the Company's oil production to a point of sale.

(c)Net natural gas plant income represents the earnings from the Company's ownership share of gas processing facilities that gather and process the Company's and third party gas.

The change in the Company's production costs per BOE during the three months ended March 31, 2023, as compared to the same period in 2022, is due to the following:

•Lease operating expense per BOE increased primarily due to inflationary pressures on power, chemicals and labor costs;

•Gathering, processing and transportation expense per BOE decreased primarily due to decreased gas processing costs as a result of a decrease in gas and NGL prices, which are used to value contractual volumes retained by the gas processor as payment for their services;

•Workover costs per BOE increased due to increased workover costs due to inflationary pressures; and

•Net natural gas plant income per BOE decreased primarily due to decreases in gas and NGL prices.

Production and ad valorem taxes per BOE are as follows:

	Three Months Ended March 31,
	2023		2022		% Change
Production taxes per BOE	$	2.46	$	3.25	(24	%)
Ad valorem taxes per BOE	0.93		0.65		43	%
	$	3.39	$	3.90	(13	%)

In general, production taxes and ad valorem taxes are directly related to commodity price changes; however, Texas ad valorem taxes are based upon prior year commodity prices, whereas production taxes are based upon current year commodity prices.

The change in production taxes per BOE for the three months ended March 31, 2023, as compared to the same period in 2022, is due to the aforementioned decrease in commodity prices. The change in ad valorem taxes per BOE for the three months ended March 31, 2023, as compared to the same period in 2022, is primarily due to an increase in prior year commodity prices that are used to determine current year ad valorem taxes.

The change in geological and geophysical costs for the three months ended March 31, 2023, as compared to the same period in 2022, is primarily due to $2 million for licensing of certain seismic data in the Company's area of operations.

Leasehold abandonment costs primarily represent the abandonment of certain unproved properties that the Company no longer plans to drill before the leases expire.

During the three months ended March 31, 2023 and 2022, the Company drilled and evaluated 123 and 122 exploratory/extension wells, respectively, with 100 percent successfully completed as discoveries.

The change in cash general and administrative expense per BOE for the three months ended March 31, 2023, as compared to the same period in 2022, is primarily due to the aforementioned seven percent increase in daily sales volumes due to the Company's successful Spraberry/Wolfcamp horizontal drilling program, partially offset by increases in labor costs. The change in noncash general and administrative expense per BOE for the three months ended March 31, 2023, as compared to the same period in 2022, is primarily due to changes in the market value of investments underlying the Company's deferred compensation obligation.

The change in cash interest expense for the three months ended March 31, 2023, as compared to the same period in 2022, is primarily due to (i) the early extinguishment of the Company's 0.750% senior notes due 2024 and the 4.450% senior notes due 2026 during February 2022, (ii) the repayment of the Company's 3.950% senior notes due 2022 that matured in July 2022 and (iii) the early extinguishment of the Company's 5.625% senior notes due 2027 during October 2022.

The weighted average cash interest rate on the Company's indebtedness for the three months ended March 31, 2023 decreased to 1.7 percent, as compared to 1.8 percent for the same period in 2022.

	(in millions, except percentages)
Income tax provision	$	(335)		$	(552)		$	217
Effective tax rate	22		%	22		%	—		%

The change in income tax provision for the three months ended March 31, 2023, as compared to the same period in 2022, is primarily due to a decrease of $1.0 billion in income before income taxes. The Company evaluates and updates its annual effective income tax rate on an interim basis based on current and forecasted earnings and tax laws. The mix and timing of the Company's actual earnings compared to annual projections can cause interim effective tax rate fluctuations. The Company's interim effective tax rate for the three months ended March 31, 2023 and 2022 differed from the U.S. statutory rate of 21 percent primarily due to forecasted state income taxes.

On August 16, 2022, President Biden signed into law the IRA, which includes among other things, the CAMT. Under the CAMT, a 15 percent minimum tax will be imposed on certain adjusted financial statement income of "applicable corporations," which is effective for tax years beginning after December 31,2022. The CAMT generally treats a corporation as an "applicable corporation" in any taxable year in which the "average annual adjusted financial statement income" of the corporation and certain of its subsidiaries and affiliates for a three-taxable-year period ending prior to such taxable year exceeds $1 billion. The Company will continue to monitor and assess any impacts of the IRA on the Company's current year tax provision or the Company's consolidated financial statements.

See Note 14 of Notes to Consolidated Financial Statements included in "Item 1. Financial Statements" for additional information.

Liquidity and Capital Resources

Liquidity. The Company's primary sources of short-term liquidity are (i) cash and cash equivalents, (ii) net cash provided by operating activities, (iii) sales of investments, (iv) unused borrowing capacity under its Credit Facility, (v) issuances of debt or equity securities and (vi) other sources, such as sales of nonstrategic assets.

The Company's short-term and long-term liquidity requirements consist primarily of (i) capital expenditures, (ii) acquisitions of oil and gas properties, (iii) payments of contractual obligations, including debt maturities, (iv) dividends and share repurchases, (v) income taxes and (vi) working capital obligations. Funding for these requirements may be provided by any combination of the Company's sources of liquidity. Although the Company expects that its sources of funding will be adequate to fund its 2023 liquidity requirements, no assurance can be given that such funding sources will be adequate to meet the Company's future needs.

2023 capital budget. The Company's capital budget for 2023 is expected to be in the range of (i) $4.45 billion to $4.75 billion of development related capital, which includes drilling and completion related activities, and the construction of tank batteries, saltwater disposal facilities and water infrastructure, and (ii) $150 million to $200 million of exploration, environmental and other capital, principally related to drilling four Barnett/Woodford formation wells in the Midland Basin, additional testing of the Company's enhanced oil recovery project and adding electric power infrastructure for future drilling, completions and production operations. The 2023 capital budget excludes acquisitions, asset retirement obligations, capitalized interest, geological and geophysical general and administrative expense, corporate facilities and vehicles.

The 2023 capital budget is expected to be funded from operating cash flow and, if necessary, from cash and cash equivalents on hand or borrowings under the Company's Credit Facility.

Capital resources. As of March 31, 2023, the Company had no outstanding borrowings under its Credit Facility, leaving $2.0 billion of unused borrowing capacity. The Credit Facility requires the maintenance of a ratio of total debt to book capitalization, subject to certain adjustments, not to exceed 0.65 to 1.0. The Company was in compliance with all of its debt covenants as of March 31, 2023. The Company also had unrestricted cash on hand of $1.2 billion as of March 31, 2023.

PIONEER NATURAL RESOURCES COMPANY

Sources and uses of cash during the three months ended March 31, 2023, as compared to the same period in 2022, are as follows:

	Three Months Ended March 31,
	2023		2022		Change
	(in millions)
Net cash provided by operating activities	$	2,314	$	2,581	$	(267)

Net cash used in financing activities	$	(950)	$	(2,761)	$	(1,811)

Operating activities. The change in net cash flow provided by operating activities for the three months ended March 31, 2023, as compared to the same period in 2022, is primarily due to (i) a decrease in oil and gas revenues, primarily due to a 25 percent decrease in average realized commodity prices per BOE in 2023 due to the aforementioned instability in worldwide oil and gas demand, partially offset by a seven percent increase in daily sales volumes due to the Company's successful Spraberry/Wolfcamp horizontal drilling program and (ii) an increase in the current income tax provision, partially offset by a decrease in cash used in derivative activities.

Investing activities. The Company's significant investing activities for the three months ended March 31, 2023 and 2022 are as follows:

•2023: The Company (i) used $1.2 billion for additions to oil and gas properties, (ii) used $28 million for additions to other assets and other property, plant and equipment and (iii) received proceeds from disposition of assets of $4 million.

•2022: The Company (i) used $914 million for additions to oil and gas properties, (ii) purchased commercial paper for $640 million, net of $2 million of discounts, (iii) received proceeds from the disposition of assets of $210 million, (iv) received proceeds from the sale of the short-term investment in Laredo common stock of $75 million and (v) used $41 million for additions to other assets and other property, plant and equipment.

Financing activities. The Company's significant financing activities for the years ended March 31, 2023 and 2022 are as follows:

•2023: The Company (i) paid dividends of $1.3 billion, (ii) received proceeds from the March 2023 Senior Notes Offering, net of $7 million of issuance costs and discounts, of $1.1 billion, (iii) repurchased $520 million of its common stock, (iv) borrowed and repaid $350 million on its Credit Facility, (v) paid $230 million to settle exercised conversion options related to the Company's Convertible Notes, (vi) received $31 million in Capped Call proceeds related to the aforementioned exercised conversion options and (vii) paid $4 million of other liabilities.

•2022: The Company (i) redeemed $1.3 billion of its outstanding 0.750% senior notes due 2024 and 4.450% senior notes due 2026, having aggregate principal amounts of $750 million and $500 million, respectively, (ii) paid dividends of $1.1 billion, (iii) repurchased $276 million of its common stock and (iv) paid $121 million of other liabilities.

Dividends. During the three months ended March 31, 2023, the Company declared base dividends of $260 million, or $1.10 per share, compared to $191 million, or $0.78 per share, during the three months ended March 31, 2022.

In addition to its base dividend program, the Company has a variable dividend strategy whereby the Company pays a quarterly variable dividend of up to 75 percent of the prior quarter's free cash flow remaining after its base dividend. In April 2023, the Company modified its variable dividend strategy to return 75 percent of the prior quarter's free cash flow inclusive of its base dividend and share repurchases. The modified variable dividend strategy will be effective for variable dividends declared by the Board subsequent to April 2023. 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, 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. Capital expenditures exclude acquisitions, asset retirement obligations, capitalized interest, geological and geophysical general and administrative expenses, information technology capital investments, vehicles and additions to corporate facilities. During the three months ended March 31, 2023, the Company declared variable dividends of $1.1 billion, or $4.48 per share, compared to $731 million, or $3.00 per share, during the three months ended March 31, 2022.

On April 26, 2023, the Board declared a quarterly base dividend of $1.25 per share and a quarterly variable dividend of $2.09 per share for shareholders of record on June 1, 2023, with a payment date of June 21, 2023. Future base and variable

35

PIONEER NATURAL RESOURCES COMPANY

dividends are at the discretion of the Board, and, if declared, the Board may change the dividend amount based on the Company's outlook for commodity prices, liquidity, debt levels, capital resources, free cash flow or other factors. The Company can provide no assurance that dividends will be authorized or declared in the future or as to the amount of any future dividends. Any future variable dividends, if declared and paid, will fluctuate based on the Company's free cash flow and share repurchases, which will depend on a number of factors beyond the Company's control, including commodity prices and the Company's share price.

Off-balance sheet arrangements. From time to time, the Company enters into arrangements and transactions that can give rise to material off-balance sheet obligations of the Company. As of March 31, 2023, the material off-balance sheet arrangements and transactions that the Company had entered into included (i) firm purchase, transportation, storage and fractionation commitments, (ii) open purchase commitments and (iii) contractual obligations for which the ultimate settlement amounts are not fixed and determinable. The contractual obligations for which the ultimate settlement amounts are not fixed and determinable include (a) derivative contracts that are sensitive to future changes in commodity prices, or the Company's share price, (b) gathering, processing and transportation commitments on uncertain volumes of future throughput and (c) indemnification obligations following certain divestitures.

In connection with its divestiture transactions, the Company may retain certain liabilities and provide the purchaser certain indemnifications, subject to defined limitations, which may apply to identified pre-closing matters, including matters of litigation, environmental contingencies, royalties and income taxes. Also associated with its divestiture transactions, the Company has issued and received guarantees to facilitate the transfer of contractual obligations, such as firm transportation agreements or gathering and processing arrangements. The Company does not recognize a liability if the fair value of the obligation is immaterial or the likelihood of making payments under these guarantees is remote.

Other than the off-balance sheet arrangements described above, the Company has no transactions, arrangements or other relationships with unconsolidated entities or other persons that are reasonably likely to materially affect the Company's liquidity or availability of or requirements for capital resources. The Company expects to enter into similar contractual arrangements in the future and additional firm purchase, transportation, storage and fractionation arrangements, in order to support the Company's business plans. See Note 10 of Notes to Consolidated Financial Statements included in "Item 1. Financial Statements" for additional information.

Convertible senior notes. In May 2020, the Company issued $1.3 billion principal amount of convertible senior notes due 2025. The Convertible Notes bear a fixed interest rate of 0.250% per year, with interest payable on May 15 and November 15 of each year. The Convertible Notes will mature on May 15, 2025, unless earlier redeemed, repurchased or converted. The Convertible Notes are unsecured obligations ranking equally in right of payment with all other senior unsecured indebtedness of the Company.

The Convertible Notes are convertible into shares of the Company's common stock at an adjusted conversion rate of 10.5356 shares of the Company's common stock per $1,000 principal amount of the Convertible Notes subject to the Conversion Rate, which represents an adjusted Conversion Price of $94.92 per share as of March 31, 2023. As a result of the quarterly base and variable dividends declared through March 31, 2023, the Conversion Rate increased from the initial rate of 9.1098 shares of the Company's common stock per $1,000 principal amount of the Convertible Notes and the Conversion Price decreased from $109.77. Future declarations of quarterly base and variable dividends in excess of $0.55 per common share will cause further adjustments to the Conversion Rate and the Conversion Price pursuant to the terms of the notes indenture. Upon conversion, the Convertible Notes may be settled in cash, shares of the Company's common stock or a combination thereof, at the Company's election.

Holders of the Convertible Notes may convert their notes at their option prior to February 15, 2025 under the following circumstances:

•during the quarter following any quarter during which the last reported sales price of the Company's common stock for at least 20 of the last 30 consecutive trading days of such quarter exceeds 130 percent of the Conversion Price;

•during the five-day period following any five consecutive trading day period when the trading price of the Convertible Notes is less than 98 percent of the product of the last reported sales price of the Company's common stock and the Conversion Rate;

•upon notice of redemption by the Company; or

•upon the occurrence of specified corporate events, including certain consolidations or mergers.

On or after February 15, 2025, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their notes at any time. The Company may not redeem the Convertible Notes prior to May 20, 2023, and after such date, may redeem the Convertible Notes only if the last reported sale price of the Company's common stock has been at least 130 percent of the Conversion Price for at least 20 trading days (whether or not consecutive) during any

36

PIONEER NATURAL RESOURCES COMPANY

30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which the Company provides the notice of redemption. The redemption price is equal to 100 percent of the principal amount of the Convertible Notes to be redeemed, plus accrued and unpaid interest.

During the last 30 consecutive trading days of the first quarter of 2023, the last reported sales prices of the Company's common stock exceeded 130 percent of the Conversion Price for at least 20 trading days, causing the Convertible Notes to become convertible at the option of the holders during the three month period ending June 30, 2023. During the three months ended March 31, 2023, the Company made total cash payments of $223 million related to the settlement of exercised conversion options on its Convertible Notes. As of March 31, 2023, $65 million of the principal amount of the Convertible Notes remains in the Settlement Period. The Company reserves its right under the notes indenture to elect to settle the Convertible Notes in cash, shares of the Company's common stock or a combination of cash and common stock. See Note 7 of Notes to Consolidated Financial Statements included in "Item 1. Financial Statements" for additional information.

Contractual obligations. The Company's contractual obligations include long-term debt, leases (primarily related to contracted drilling rigs, office facilities and other equipment), capital funding obligations, derivative obligations, firm transportation, storage and fractionation commitments, minimum annual gathering, processing and transportation commitments and other liabilities. Other joint owners in the properties operated by the Company could incur portions of the costs represented by these commitments.

Firm commitments. The Company has short-term and long-term firm purchase, gathering, processing, transportation, fractionation and storage commitments representing take-or-pay agreements, which include contractual commitments (i) to purchase sand, water and diesel for use in the Company's drilling and completion operations, (ii) with midstream service companies and pipeline carriers for future gathering, processing, transportation, fractionation and storage and (iii) with oilfield services companies that provide drilling and pressure pumping services. The Company does not expect to be able to fulfill all of its short-term and long-term firm transportation volume obligations from projected production of available reserves; consequently, the Company plans to purchase third party volumes to satisfy its firm transportation commitments if it is economic to do so; otherwise, it will pay demand fees for any commitment shortfalls. The Company also has open purchase commitments for inventories, materials and other property and equipment ordered, but not received, as of March 31, 2023.

Long-term debt. As of March 31, 2023, the Company's outstanding debt is comprised of senior notes and convertible senior notes. The senior notes and convertible senior notes issued by the Company rank equally, but are structurally subordinated to all obligations of the Company's subsidiaries. See Note 7 of Notes to Consolidated Financial Statements included in "Item 1. Financial Statements" for additional information.

Operating leases. The Company's short-term and long-term lease obligations primarily relate to contracted drilling rigs, storage tanks, equipment and office facilities.

Derivative obligations. The Company's commodity, marketing and conversion option derivatives are periodically measured and recorded at fair value and continue to be subject to market and/or credit risk. As of March 31, 2023, these contracts represented net liabilities of $175 million. The ultimate liquidation value of the Company's commodity and marketing derivatives will be dependent upon actual future commodity prices, which may differ materially from the inputs used to determine the derivatives' fair values as of March 31, 2023. The ultimate liquidation of the Company's conversion option derivatives will be dependent on the Company's daily volumetric weighted average share price during the Settlement Period. See Note 4 and Note 5 of Notes to Consolidated Financial Statements included in "Item 1. Financial Statements" and "Item 3. Quantitative and Qualitative Disclosures About Market Risk" for additional information.

Other liabilities. The Company's other liabilities represent current and noncurrent other liabilities that are primarily comprised of litigation and environmental contingencies, asset retirement obligations, a finance lease for the corporate headquarters office building, the deferred compensation retirement plan obligation and other obligations for which neither the ultimate settlement amounts nor their timings can be precisely determined in advance. See Note 9 and Note 10 of Notes to Consolidated Financial Statements included in "Item 1. Financial Statements" for additional information.

ITEM 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

In the normal course of business, the Company's financial position is routinely subject to a variety of risks, including market risks associated with changes in commodity prices, changes in the Company's share price, which impacts the settlement value of convertible notes where holders have exercised their conversion option, interest rate movements on outstanding debt and credit risks. The following quantitative and qualitative information is provided about financial instruments to which the Company was a party as of March 31, 2023, and from which the Company may incur future gains or losses from changes in commodity prices, or the Company's share price. The Company does not enter into any financial instruments, including derivatives, for speculative or trading purposes.

37

PIONEER NATURAL RESOURCES COMPANY

Commodity price risk. The Company's primary market risk exposure is related to the price it receives from the sale of its oil, NGL and gas production. Realized pricing is volatile and is determined by market prices that fluctuate with changes in supply and demand for these products throughout the world. The price the Company receives for its production depends on many factors outside of the control of the Company, including differences in commodity pricing at the point of sale versus market index prices. The Company's exposure to price volatility impacts funds available to primarily be used in its capital program, general working capital needs, debt obligations, dividends and share repurchases. The Company mitigates its commodity price risk by (i) maintaining financial flexibility with a strong balance sheet, (ii) using derivative financial instruments and (iii) sales of purchased commodities.

Commodity price derivatives. The Company primarily utilizes derivative contracts to reduce the effect of price volatility on the commodities the Company produces and sells. The Company's decision on the quantity and price at which it executes commodity derivative contracts, if it so chooses, is based in part on its view of current and future market conditions. The Company may choose not to enter into derivative positions for expected production if the commodity price forecast for certain time periods is deemed to be unfavorable. Additionally, the Company may choose to liquidate existing derivative positions prior to the expiration of their contractual maturity in order to monetize gain positions or minimize loss positions if it is anticipated that the commodity price forecast is expected to improve. Proceeds, if any, can be used for the purpose of funding the Company's capital program, general working capital needs, debt obligations, dividends and share repurchases, among other uses. While derivative positions limit the downside risk of adverse price movements, they also limit future revenues from upward price movements.

As of March 31, 2023, the Company did not have any material outstanding commodity derivative contracts. See Note 4 and Note 5 of Notes to Consolidated Financial Statements included in "Item 1. Financial Statements" for a description of the Company's open derivative positions and additional information.

Sales of purchased commodities. The Company enters into pipeline capacity commitments in order to secure available oil, NGL and gas transportation capacity from the Company's areas of production and to secure diesel supply from the Gulf Coast. The Company also enters into purchase commitments to secure sand supply for the Company's operations in the Midland Basin. The Company enters into purchase transactions with third parties and separate sale transactions with third parties to diversify a portion of the Company's oil and gas sales to (i) Gulf Coast refineries, (ii) Gulf Coast and West Coast gas markets and (iii) international oil markets, and to satisfy unused gas pipeline capacity commitments. The Company periodically sells diesel and sand to unaffiliated third parties in the Permian Basin if it has supply in excess of its operational needs.

Marketing derivatives. The Company uses marketing derivatives to diversify its oil pricing to Gulf Coast and international markets. As of March 31, 2023, 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 the WASP 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.

The Company could experience mark-to-market fluctuations in the fair value of its marketing derivatives based on changes in (i) the differential between Midland WTI and Brent and (ii) the WASP Differential Deduction if it deviates from historical levels. For example, a 10 percent increase or decrease in the differential between Midland WTI and Brent would impact the fair value of the Company's marketing derivatives recorded by $54 million and a 10 percent increase or decrease in the WASP Differential Deduction would impact the fair value of the Company's marketing derivatives recorded by $29 million as of March 31, 2023. See Note 4 and Note 5 of Notes to Consolidated Financial Statements included in "Item 1. Financial Statements" for a description of the Company's open derivative positions and additional information.

Company share price risk. When holders of the Company's Convertible Notes exercise their conversion option, the Company is subject to market risks related to changes in the Company's share price that occur during the Settlement Period. See Note 4, Note 5 and Note 7 of Notes to Consolidated Financial Statements included in "Item 1. Financial Statements" for a description of the Company's open derivative positions and additional information.

Interest rate risk. As of March 31, 2023, the Company had no variable rate debt outstanding under the Credit Facility and, consequently, no related exposure to interest rate risk. As of March 31, 2023, the Company had $5.9 billion of fixed rate long-term debt outstanding with a weighted average cash interest rate of 2.3 percent. Although changes in interest rates may

affect the fair value of the Company's fixed rate long-term debt, any changes would not expose the Company to the risk of earnings or cash flow losses. The Company has no interest rate derivative instruments outstanding; however, it may enter into derivative instruments in the future to mitigate interest rate risk. See Note 4 and Note 7 of Notes to Consolidated Financial Statements included in "Item 1. Financial Statements" for additional information.

Credit risk. The Company's primary concentration of credit risks are associated with the collection of receivables resulting from the sale of oil and gas production and purchased commodities, and the risk of a counterparty's failure to meet its obligations under derivative contracts with the Company.

The Company's commodities are sold to various purchasers who must be prequalified under the Company's credit risk policies and procedures. The Company monitors exposure to counterparties primarily by reviewing credit ratings, financial criteria and payment history. Where appropriate, the Company obtains assurances of payment, such as a guarantee by the parent company of the counterparty, a letter of credit or other credit support. Historically, the Company's credit losses on commodity receivables have not been material.

The Company uses credit and other financial criteria to evaluate the credit standing of, and to select, counterparties to its derivative instruments. Although the Company does not obtain collateral or otherwise secure the fair value of its derivative instruments, associated credit risk is mitigated by the Company's credit risk policies and procedures.

The Company has entered into International Swap Dealers Association Master Agreements ("ISDA Agreements") with each of its commodity derivative counterparties. The terms of the ISDA Agreements provide the Company and the counterparties with right of set off upon the occurrence of defined acts of default by either the Company or a counterparty to a derivative contract, whereby the party not in default may set off all derivative liabilities owed to the defaulting party against all derivative asset receivables from the defaulting party. See Note 5 of Notes to Consolidated Financial Statements included in "Item 1. Financial Statements" for additional information.

ITEM 4.    CONTROLS AND PROCEDURES

Evaluation of disclosure controls and procedures. The Company's management, with the participation of its principal executive officer and principal financial officer, have evaluated, as required by Rule 13a-15(b) under the Securities Exchange Act of 1934 (the "Exchange Act"), the effectiveness of the Company's disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e)) as of the end of the period covered by this Report. Based on that evaluation, the principal executive officer and principal financial officer concluded that the Company's disclosure controls and procedures were effective, as of the end of the period covered by this Report, in ensuring that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, including that such information is accumulated and communicated to the Company's management, including the principal executive officer and principal financial officer, to allow timely decisions regarding required disclosure.

Changes in internal control over financial reporting. There have been no changes to the Company's internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during the three months ended March 31, 2023 that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1.    LEGAL PROCEEDINGS

The Company is party to various proceedings and claims incidental to its business. While many of these matters involve inherent uncertainty, the Company believes that the amount of the liability, if any, ultimately incurred with respect to these proceedings and claims will not have a material adverse effect on the Company's consolidated financial position as a whole or on its liquidity, capital resources or future annual results of operations. 

ITEM 1A.    RISK FACTORS

In addition to the information set forth in this Report, the risks that are discussed in the Company's Annual Report on Form 10-K for the year ended December 31, 2022, under the headings "Part I, Item 1. Business – Competition," "Part I. Item 1. Business - Regulation," "Part I, Item 1A. Risk Factors," "Part II, Item 7A. Quantitative and Qualitative Disclosures About Market Risk" should be carefully considered, as such risks could materially affect the Company's business, financial condition or future results. There has been no material change in the Company's risk factors that were described in the Company's 2022 Annual Report on Form 10-K.
