Prior to , 2023 in the case of the 2028 notes and , 2025 in the case of the 2030 notes, we may redeem the applicable notes, in whole or in part, at a price equal to 100% of the principal amount thereof, plus a "make whole" premium, plus any accrued and unpaid interest. We are also entitled to redeem up to 35% of the aggregate principal amount of each series of notes before , 2023, with an aggregate amount of cash not greater than the net proceeds that we raise in certain equity offerings at a redemption price equal to % of the principal amount of the 2028 notes being redeemed, plus any accrued and unpaid interest and a redemption price equal to % of the principal amount of the 2030 notes being redeemed, plus any accrued and unpaid interest.

We intend to use the net proceeds of this offering to finance a portion of the cash consideration for the acquisition of Felix Energy Holdings II, LLC ("Felix"), including the repayment of any outstanding debt of Felix as described in this prospectus supplement, and to pay related fees and expenses. This offering is not contingent on the consummation of the Acquisition (as defined herein). However, the gross proceeds of this offering (together with any other property from time to time held in the escrow account, the "Escrow Property") will be deposited into an escrow account upon the closing of the offering. In order to cause the Escrow Agent (as defined herein) to release the Escrow Property to us, on or prior to July 15, 2020 (the "Outside Date"), we must deliver an officer's certificate to the escrow agent certifying that the Acquisition will be consummated simultaneously or substantially concurrent with the release of funds from the escrow account (the "Escrow Release Condition"). If (i) the Escrow Release Condition has not been satisfied prior to 11:59 p.m. (New York City time) on the Outside Date or (ii) we deliver a termination notice to the Escrow Agent prior to 11:59 p.m. (New York City time) on the Outside Date indicating that (a) we will not pursue the consummation of the Acquisition or (b) we have determined in our sole discretion that the Escrow Release Condition cannot or is not reasonably likely to be satisfied by 11:59 p.m. (New York City time) on the Outside Date (any event described in clauses (i) or (ii) of this sentence, a "Special Mandatory Redemption Event"), the notes will be subject to a special mandatory redemption, at a price equal to 100% of the initial issue price of the notes, plus accrued and unpaid interest from the date of initial issuance of the notes to, but not including, the Special Mandatory Redemption Date (as defined herein) (the "Special Mandatory Redemption Price"). See "Description of Notes—Escrow of Proceeds; Special Mandatory Redemption."

The notes will not be secured by any lien over the Escrow Property.

The notes will be effectively subordinated to all of our future secured indebtedness to the extent of the value of the assets securing such indebtedness and will be structurally subordinated to all existing and future indebtedness and other liabilities of our subsidiaries. The notes will rank senior to all of our future subordinated indebtedness.

This prospectus supplement, the accompanying base prospectus, any free writing prospectus and the documents incorporated by reference herein and in the accompanying base prospectus include forward-looking statements made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. These forward-looking statements are subject to a number of risks and

uncertainties, many of which are beyond our control. These forward-looking statements relate to anticipated financial performance, management's plans and objectives for future operations, business prospects, outcome of regulatory proceedings, market conditions and other matters.

All statements, other than statements of historical facts, included in any of the foregoing documents that address activities, events or developments that we expect, believe or anticipate will exist or may occur in the future, are forward-looking statements.

Forward-looking statements can be identified by various forms of words such as "anticipates," "believes," "seeks," "could," "may," "should," "continues," "estimates," "expects," "forecasts," "intends," "might," "goals," "objectives," "targets," "planned," "potential," "projects," "scheduled," "will" or other similar expressions.

Forward-looking statements are based on numerous assumptions, uncertainties and risks that could cause future events or results to be materially different from those stated or implied in this prospectus supplement, the accompanying base prospectus or the documents incorporated by reference herein or therein. Many of the factors that will determine these results are beyond our ability to control or predict. Specific factors that could cause actual results to differ from results contemplated by the forward-looking statements include, among others, the following:

All forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by the cautionary statements set forth above. Given the uncertainties and risk factors that could cause our actual results to differ materially from those contained in any forward-looking statement, we caution investors not to unduly rely on our forward-looking statements. Forward-looking statements speak only as of the date they are made. We disclaim any obligation to and do not intend to update the above list or to announce publicly the result of any revisions to any of the forward-looking statements to reflect future events or developments, except to the extent required by applicable laws. If we update one or more forward-looking statements, no inference should be drawn that we will make additional updates with respect to those or other forward-looking statements.

In addition to causing our actual results to differ, the factors listed above and referred to below may cause our intentions to change from those statements of intention set forth in or incorporated by reference in this prospectus supplement or the accompanying base prospectus. Such changes in our intentions may also cause our results to differ. We may change our intentions, at any time and without notice, based upon changes in such factors, our assumptions, or otherwise.

We refer to the term Adjusted EBITDAX (as described in "Summary—Summary Historical Consolidated Financial Data of WPX" and "Summary—Summary Unaudited Pro Forma Condensed Combined Financial Information") in various places in this prospectus supplement. Adjusted EBITDAX is a supplemental financial measure that is not prepared in accordance with generally accepted accounting principles in the United States, or GAAP. This measure excludes a number of significant items, including our interest expense and depreciation, depletion and amortization expense. Our measurement of Adjusted EBITDAX may not be comparable to those of other companies. Please see "Summary—Summary Historical Consolidated Financial Data of WPX" for a discussion of our use of such measure and a reconciliation of Adjusted EBITDAX to the most closely comparable financial measures calculated in accordance with GAAP.

We also refer to PV-10 in this prospectus supplement (as described in "Summary—Summary Historical Reserve and Operating Data of WPX"). The present value of estimated future net revenues discounted at an annual rate of 10 percent ("PV-10") is not a GAAP financial measure and is derived from the standardized measure, which is the most directly comparable GAAP financial measure. PV-10

is a computation of the standardized measure on a pre-tax basis. PV-10 is equal to the standardized measure of discounted future net cash flows at the applicable date, before deducting future income taxes, discounted at 10 percent. Please see "Summary—Summary Historical Reserve and Operating Data of WPX" for a discussion of our use of such measure and a reconciliation of PV-10 to the most closely comparable financial measure calculated in accordance with GAAP.

In this prospectus supplement, the following terms have the meanings specified below.

Barrel—means one barrel of petroleum products that equals 42 U.S. gallons.

Boe—means one barrel of oil equivalent, calculated by converting natural gas volumes to equivalent oil barrels at a ratio of six Mcf to one barrel of oil.

British Thermal Unit or BTU—means a unit of energy needed to raise the temperature of one pound of water by one degree Fahrenheit.

LOE—means lease and other operating expense excluding production taxes, ad valorem taxes and gathering, processing and transportation fees.

NGL—means natural gas liquids; natural gas liquids result from natural gas processing and crude oil refining and are used as petrochemical feedstocks, heating fuels and gasoline additives, among other applications.

SUMMARY

This summary highlights certain information concerning our business, this offering and the Acquisition. It does not contain all of the information that may be important to you and to your investment decision. The following summary is qualified in its entirety by the more detailed information and financial statements and notes thereto in this prospectus supplement and the accompanying base prospectus and the documents incorporated by reference herein and therein. You should carefully read this entire prospectus supplement, the accompanying base prospectus and the documents incorporated by reference herein and therein and should consider, among other things, the matters set forth and incorporated by reference in "Risk Factors" before deciding to invest in the notes. In addition, unless we specifically state otherwise, the information in this prospectus supplement and the accompanying prospectus, including the documents incorporated by reference herein and therein, does not give effect to the Acquisition.

Our Company

Incorporated in 2011, WPX Energy, Inc. is an independent oil and natural gas exploration and production company engaged in the exploitation and development of long-life unconventional properties. We are focused on profitably exploiting, developing and growing our oil positions in the Delaware Basin (a subset of the Permian Basin) in Texas and New Mexico and the Williston Basin in North Dakota. Our principal executive office is located at 3500 One Williams Center, Tulsa, Oklahoma 74172. Our telephone number is 855-979-2012. We maintain an Internet site at www.wpxenergy.com. Except for our filings with the SEC that are incorporated by reference into this prospectus supplement or the accompanying base prospectus, the information on or accessible through our website is not a part of this prospectus supplement or the accompanying base prospectus.

Our Business Strategy

Focused, Long-Term Portfolio Management. We are focused on long-term profitable growth. Our objective over time is disciplined production growth within our cash flow and to reduce our costs. With that in mind, we regularly evaluate the performance of our assets and, when appropriate, we consider divestitures of assets that are underperforming or which are no longer a part of our strategic focus. Since mid-2014, we have undertaken $8 billion of asset acquisitions and divestitures, allowing us to focus on our core areas and strengthen our financial position, not taking into account our acquisition of Felix (described herein). We will allocate capital to the most profitable opportunities based on expected returns, commodity price cycles and other market conditions, enabling us to grow our reserves and production in a manner that maximizes our returns on investments.

Margin Expansion through Focus on Costs. We believe we can expand our margins by focusing on opportunities to reduce our cost structure and being disciplined both operationally and financially. This requires consistent execution as well as managing potential disruptions in our business. We continue to manage the cost and availability of skilled labor, drilling rigs and equipment, transportation and other supplies.

Maintain Financial Flexibility. We believe our continued focus on cost reductions, increased capital efficiency and disciplined production growth will allow us to generate increased and sustainable annual cash flows from operations. This cash flow, combined with our capital structure and available sources of liquidity, will allow us to efficiently develop and grow our resource base and pursue reserve growth throughout a variety of commodity price environments. We have engaged and will continue to engage in commodity derivative hedging activities to maintain a degree of cash flow certainty. Typically, we target hedging at least 50 percent of expected revenue from production during a current calendar year in order to strike an appropriate balance of commodity price upside with cash flow protection, although we may vary from this level based on our perceptions of market risk and the impact of such decisions on our leverage and ability to be cash flow neutral.

Build Asset Scale and Remain Opportunistic. We may opportunistically acquire acreage positions in areas where we feel we can establish significant scale and replicate cost-efficient development practices. We may also consider other "bolt-on" transactions or leasehold exchanges that are directed at driving operational efficiencies through increased scale or contiguous acreage blocks. We can manage costs by focusing on the establishment of large scale, contiguous acreage blocks where we can operate a majority of the properties. We believe this strategy allows us to better achieve economies of scale and apply continuous technological improvements in our operations. We have a history of acquiring undeveloped properties that meet our expected return requirements and other acquisition criteria to expand upon our existing positions as well as acquiring undeveloped acreage in new geographic areas that offer significant resource potential.

Felix Acquisition

On December 15, 2019, we entered into a Securities Purchase Agreement (the "Purchase Agreement") with Felix Investments Holdings II, LLC ("Felix Parent") to acquire all of the issued and outstanding membership interests of Felix (the "Acquisition"), for consideration of approximately $2.5 billion ("Purchase Price"), consisting of $900 million in cash (such amount the "Unadjusted Cash Purchase Price") and 152,963,671 unregistered shares of our common stock valued at $10.46 per share (the "Unadjusted Equity Consideration"). The Purchase Price is subject to customary closing adjustments. We expect to close the Acquisition in the first half of 2020, subject to satisfaction of customary closing conditions.

Felix Parent has a senior secured notes facility pursuant to that certain Note Purchase Agreement, dated as of August 9, 2017 (as amended, restated, amended and restated, supplemented and otherwise modified prior to the date hereof, the "Felix Parent Notes Facility"), and Felix has a reserve-based revolving credit facility pursuant to that certain Credit Agreement dated as of July 1, 2016 (as amended, restated, amended and restated, supplemented and otherwise modified prior the date hereof, the "Felix Revolving Credit Facility" and together with the Felix Parent Notes Facility, the "Felix Debt Facilities"). The Felix Parent Notes Facility is secured by a lien on the equity of Felix and certain of Felix's assets. As a condition to and simultaneous with the closing of the Acquisition, all remaining amounts outstanding under the Felix Debt Facilities are to be repaid in order to cause the release of such liens and terminate the facilities. Any amounts outstanding under the Felix Debt Facilities that are repaid from the Unadjusted Cash Purchase Price in connection with and simultaneous with the closing of the Acquisition will result in a reduction in the Unadjusted Cash Purchase Price received by Felix Parent. Furthermore, in connection with entering into the Purchase Agreement, Felix Parent received commitments from certain of its affiliates to finance the repayment of any amounts outstanding under the Felix Debt Facilities to the extent such amounts outstanding exceed the Unadjusted Cash Purchase Price subject to certain adjustments.

Pursuant to the Purchase Agreement, Felix Parent will receive our common stock as consideration and Felix Parent (and/or certain of Felix Parent's direct or indirect equity holders) will have registration rights with respect to such common stock. Following the Acquisition, Felix will be our wholly-owned subsidiary.

Prior to entering into the Purchase Agreement, Felix entered into a separate agreement to sell its crude midstream business for cash (the "Midstream Sale"). It is anticipated that the Midstream Sale will close prior to the closing of the Acquisition. Felix Parent will be entitled to the proceeds from the Midstream Sale and we expect Felix Parent to apply such proceeds to pay down indebtedness under the Felix Debt Facilities. If the Midstream Sale fails to close prior to the closing of the Acquisition, Felix's crude midstream business will be distributed to Felix Parent prior to the consummation of the Acquisition. Likewise, Felix will either distribute or otherwise dispose of its water business prior to consummation of the Acquisition (with Felix Parent being entitled to the proceeds of such disposition).

Neither the crude midstream business nor the water business will be acquired by us in the Acquisition.We refer to either the distribution or sale of such assets herein as the "Felix Dispositions."

Unless otherwise indicated, references in this prospectus supplement to Felix, its business or the Acquisition give effect to the Felix Dispositions, the repayment of any remaining amounts under the Felix Revolving Credit Facility and the release of any liens or securitization under the Felix Debt Facilities.

The Felix Assets

Felix is engaged in the acquisition, development and production of oil and gas properties in the Permian Basin, and more specifically in the Delaware Basin sub-area. The Permian Basin is one of the most prolific hydrocarbon producing regions in the United States and spans an area approximately 250 miles wide by 300 miles long. The basin is characterized by numerous stacked reservoirs, high oil and natural gas content, extensive production history, long-lived reserves and high drilling success rates.

All of Felix's Permian properties are located in the Delaware Basin, where it has accumulated approximately 58,500 net acres with six productive benches, with core operations located in Loving, Reeves, Ward and Winkler counties in Texas.

Felix operates 174 gross producing oil wells as of September 30, 2019 in the Delaware Basin with an average working interest of approximately 80%. Felix's average net daily production from its Delaware Basin properties for the year ended December 31, 2018 was 19.8 MBoe/d, 77% of which was oil, 12% NGLs and 11% natural gas. Felix's average net daily production for the nine months ended September 30, 2019 was 43.0 MBoe/d, 73% of which was oil, 15% NGLs and 12% natural gas. As of December 31, 2018, Felix had proved developed reserves of 87,388 MBoe, 76% of which was oil, 15% NGLs and 9% natural gas. As of December 31, 2018, Felix had 440 proved undeveloped locations based on a seven development drilling rig plan in place at such time. Felix has since reduced its drilling rigs from seven to five and as a result, Felix's proved undeveloped locations as of December 31, 2019 may be less compared to its proved undeveloped locations on December 31, 2018. In addition, the proved undeveloped reserves of Felix are based on Felix's development plans and may not necessarily reflect our development plans for these properties. Therefore, upon closing of the Acquisition, the proved undeveloped reserves booked by us may differ. We plan to continue to maintain Felix's five rig drilling program following the consummation of the Acquisition. Felix has assembled a multi-year inventory of approximately 1,500 gross drillable locations. We believe the Felix assets will further strengthen our inventory in the Permian Basin, which will consist of approximately 2,100 one-mile laterals and approximately 2,800 extended laterals after giving effect to the Acquisition.

Acquisition Rationale

We believe the Acquisition accomplishes several strategic objectives for us and is complementary to our business strategies in the following ways:

•: Accretive Across Key Metrics. We believe that the Acquisition will be accretive to cash flow, return on capital employed and cash margins.
•: Enhanced Margins and Increased Oil Inventory. Felix's production stream of approximately 70% oil will enhance near-term cash margins our oil-weighted inventory.
•: Leverage-neutral, Scale-enhancing Transaction. The Acquisition will allow us to deliver more quickly on our five-year vision of delivering value to stakeholders by improving our scale in a leverage-neutral transaction.
•: Significant Operational Synergies. The Acquisition increases our extended lateral inventory and allows us to capture significant upside by capturing synergies associated with scale.

We also plan to initiate a dividend to our equity holders after the Acquisition has been consummated.

Financing Transactions

This offering of notes is expected to be consummated prior to the closing of the Acquisition. We intend to use the net proceeds from this offering to finance a portion of the cash consideration for the Acquisition, including the repayment of any remaining amounts outstanding under the Felix Debt Facilities.

The Acquisition is not conditioned on the consummation of this offering. However, if the Acquisition is not consummated by the Outside Date or if we deliver a termination notice to the Escrow Agent indicating that we will not pursue the consummation of the Acquisition or we have determined in our sole discretion that the Escrow Release Condition cannot or is not reasonably likely to be satisfied prior thereto, the notes will be subject to a special mandatory redemption. See "Description of Notes—Escrow of Proceeds; Special Mandatory Redemption."

We cannot assure you that we will complete the Acquisition on the terms contemplated in this prospectus supplement or at all. See "Risk Factors—Risks Related to the Acquisition."

Escrow of Proceeds; Special Mandatory Redemption		This offering of notes is expected to be consummated prior to the consummation of the Acquisition. Concurrently with the initial issuance of the notes, we will enter into an escrow agreement with the Escrow Agent, pursuant to which we will deposit, or cause to be deposited, into an account under the control of the Escrow Agent the gross proceeds from the issuance of the notes (together with any other property from time to time held in the escrow account, the "Escrow Property").

Change of Control		If we experience a change of control (as defined in the indenture governing the notes) accompanied by a specified rating decline with respect to a series of notes, we must offer to repurchase such series of notes at 101% of their principal amount, plus accrued and unpaid interest, if any, to the date of purchase. See "Description of Notes—Change of Control."


Ranking		The notes will be our senior unsecured indebtedness and will rank equally in right of payment with all of our existing and future senior unsecured indebtedness. The notes will be effectively subordinated to all of our existing and future secured indebtedness to the extent of the value of the assets securing such indebtedness and will be structurally subordinated to all existing and future indebtedness and other liabilities of our subsidiaries. The notes will rank senior to all of our future subordinated indebtedness.
		As of September 30, 2019, on a pro forma basis, after giving effect to the Acquisition and this offering, (i) we would have had total indebtedness of $3,171 million, none of which was subordinated and $42 million of which was secured borrowings under our Second Amended and Restated Credit Agreement, dated as of March 18, 2016, among the Company, Wells Fargo Bank, National Association, as Administrative Agent, Lender and Swingline Lender, and the other lenders party thereto (as amended, the "Credit Facility") to fund transaction costs related to this offering and the Acquisition (excluding $37 million of outstanding letters of credit issued under the Credit Facility) and (ii) we would have had $1,421 million available for additional borrowing under our Credit Facility (after giving effect to $37 million of outstanding letters of credit issued under the Credit Facility). At the time of the Acquisition closing, the Company may elect to use cash on hand to fund the estimated $42 million in borrowings related to the transaction costs of this offering and the Acquisition rather than such borrowings under the Credit Facility. See "Description of Other Indebtedness."
Certain Covenants		We will issue the notes under an indenture and supplemental indenture between us and The Bank of New York Mellon Trust Company, N.A., as trustee. The indenture contains limitations on, among other things:
		• the grant of liens on our assets to secure certain types of indebtedness; and
		• certain mergers or consolidations and transfers of assets.
		These covenants are subject to significant exceptions. See "Description of Notes—Certain Covenants" and "Description of Debt Securities" in the accompanying base prospectus.


Use of Proceeds		We estimate that the net proceeds from this offering, after deducting underwriting discounts and commissions and estimated offering expenses, will be approximately $ million. The gross proceeds from this offering will be deposited into the escrow account. See "—Escrow of Proceeds; Special Mandatory Redemption" above and "Description of Notes—Escrow of Proceeds; Special Mandatory Redemption." Upon release from escrow if the Escrow Release Condition has been satisfied, we intend to use the net proceeds of this offering to finance a portion of the cash consideration for the Acquisition, including repayment of any remaining amounts outstanding under the Felix Debt Facilities, and to pay related fees and expenses. If a Special Mandatory Redemption Event has occurred, we intend to use the net proceeds from this offering to fund, in part, the redemption of the notes at the Special Mandatory Redemption Price. See "Use of Proceeds."
Form and Denomination		The notes will be represented by one or more global notes. The global notes will be deposited with the trustee, as custodian for The Depository Trust Company, or DTC. Ownership of beneficial interests in the global notes will be shown on, and transfers of such interests will be effected only through, records maintained in book-entry form by DTC and its direct and indirect participants, including the depositaries for Clearstream Banking S.A., Luxembourg, or Euroclear Bank S.A./N.V., as operator of the Euroclear System.
		The notes will be issued in minimum denominations of $2,000 and in integral multiples of $1,000 in excess thereof.
Absence of Public Trading Market		Each series of notes is a new issue of securities for which there is currently no established trading market. We do not intend to apply for the notes to be listed on any securities exchange or to arrange for any quotation system to quote them. The underwriters have advised us that they intend to make a market for each series of notes, but they are not obligated to do so and may discontinue market-making activities at any time. Accordingly, there can be no assurance that a liquid market for the notes will develop or be maintained. See "Risk Factors."
Trustee		The Bank of New York Mellon Trust Company, N.A.
Governing Law		New York.

Reconciliation of Adjusted EBITDAX

Adjusted EBITDAX represents earnings before interest expense, income taxes, depreciation, depletion and amortization and exploration expenses and includes adjustments for net (gain) loss on derivatives, net cash received (paid) related to settlement of derivatives, net (gain) loss on sales of assets and divestments of transportation contracts, income (loss) from discontinued operations and other adjustments reflected in the table below. We believe this non-GAAP measure provides useful information regarding our ability to meet future debt service, capital expenditures and working capital requirements.

Adjusted EBITDAX, however, is not defined by GAAP and should not be considered in isolation or as an alternative to other financial data prepared in accordance with GAAP or as an indicator of our operating performance. Adjusted EBITDAX does not represent and should not be considered as an alternative to net income, as determined in accordance with GAAP, and our calculation thereof may not be comparable to similarly entitled measures reported by other companies. Although we use adjusted EBITDAX as a measure to assess the operating performance of our business, adjusted EBITDAX has significant limitations as an analytical tool because it excludes certain material costs. For example, adjusted EBITDAX does not take into account a number of significant items, including our

interest expense and depreciation, depletion and amortization expense. Our calculation of adjusted EBITDAX for the periods presented is set forth below:

Summary Historical Reserve and Operating Data of WPX

We have significant oil and gas producing activities primarily in the Delaware and Williston Basins located in the United States. Prior to the divestiture of our predominantly natural gas assets in the San Juan Basin in December 2017, we also had significant natural gas producing assets in the San Juan Basin, which are included in the table below for the periods prior to the divestiture. We sold our remaining operations in the San Juan Basin in 2018, which are also included in the table below for the periods prior to the divestiture. Prior to the divestiture of our Piceance assets in April 2016, we also had significant oil and gas producing assets in the Piceance Basin in the United States. You should refer to "Item 1A. Risk Factors" in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018, incorporated by reference herein, and the other documents incorporated by reference herein and therein when evaluating the material presented below.

Oil and Natural Gas Reserves

We prepare our own reserves estimates and over 99 percent of our reserves as of December 31, 2018 are audited by Netherland, Sewell & Associates, Inc. We have not filed on a recurring basis estimates of our total proved net oil, NGL and natural gas reserves with any U.S. regulatory authority or agency other than with the U.S. Department of Energy and the SEC. The estimates furnished to the Department of Energy have been consistent with those furnished to the SEC.

The following table presents summary data with respect to our proved oil and natural gas reserves as of the dates indicated.

	At December 31,

	2018		2017		2016
Proved Reserves¹:
Oil (MBbls)		291,305		263,670		174,563
Natural Gas (MMcf)		617,721		591,016		734,401
NGLs (MBbls)		85,037		74,011		49,443

Total (Mboe)²		479,295		436,184		346,406



Proved Developed (Mboe)		265,756		222,685		181,797
Proved Undeveloped (Mboe)		213,539		213,499		164,609

Total (Mboe)²		479,295		436,184		346,406



PV-10 (in millions)^3,⁴	$	5,670	$	3,244	$	1,038

¹: The SEC defines proved oil and gas reserves (Rule 4-10(a) of Regulation S-X) as those quantities of oil and gas, which, by analysis of geoscience 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.
²: Total Proved Reserves for 2017 and 2016 include reserves related to the San Juan Basin, which were 52,604 Mboe and 90,961 Mboe as of December 31, 2017 and 2016, respectively. Our predominantly natural gas assets in the San Juan Basin were sold in December 2017. In March 2018, we sold our remaining operations in the San Juan Basin, comprised of an oil position in the Mancos Gallup Sandstone.
³: PV-10 is derived from the standardized measure of discounted future net cash flows, which is the most directly comparable GAAP financial measure. PV-10 is a computation

of the standardized measure of discounted future net cash flows on a pre-tax basis. PV-10 is equal to the standardized measure of discounted future net cash flows at the applicable date, before deducting future income taxes, discounted at 10 percent. We believe that the presentation of PV-10 is relevant and useful to investors because it presents the discounted future net cash flows attributable to our estimated proved reserves prior to taking into account future corporate income taxes, and it is a useful measure for evaluating the relative monetary significance of our oil and natural gas assets. Further, investors may utilize the measure as a basis for comparison of the relative size and value of our reserves to other companies. We use this measure when assessing the potential return on investment related to our oil and natural gas assets. PV-10, however, is not a substitute for the standardized measure of discounted future net cash flows. Our PV-10 measure and the standardized measure of discounted future net cash flows do not purport to present the fair value of our oil and natural gas reserves.

⁴: PV-10 for 2017 includes $433 million related to the San Juan Basin properties that were divested in March 2018.

The following table provides a reconciliation of PV-10 to the standardized measure of discounted future net cash flows at December 31, 2018, 2017 and 2016:

	At December 31,

	2018		2017		2016
	(in millions)
PV-10	$	5,670	$	3,244	$	1,038
Present value of future income taxes discounted at 10%		479		83		—	^b
Standardized measure of discounted future net cash flows^a	$	5,191	$	3,161	$	1,038

^a: Standardized Measure represents the present value of estimated future cash inflows from proved natural gas and oil reserves, less future development and production costs and income tax expenses, discounted at ten percent per annum to reflect timing of future cash flows and using certain pricing assumptions. Specifically, the average domestic oil price used in the estimates for the years ended December 31, 2018, 2017 and 2016 was $61.57, $46.39 and $35.91 per barrel, respectively. For the years ended December 31, 2018, 2017 and 2016, the average domestic natural gas price was $1.21, $1.67 and $1.74 per Mcf, respectively. The average NGL price per barrel was $26.76, $21.16 and $10.57 for the same periods. Included in the $3,244 million for 2017 is $433 million related to the proved properties in the San Juan Basin that were divested in March 2018.
^b: Our historical tax basis (i.e. future deduction for taxable income calculation) of proved properties at December 31, 2016 is greater than the total future net cash flows before taxes of the standardized measure; therefore, future taxable income would be less than zero.

The following table sets forth our estimated domestic net proved reserves for our largest areas of activity expressed by product and on an oil equivalent basis as of December 31, 2018.

	As of December 31, 2018

	Oil (Mbbls)		Gas (MMcf)		NGL (Mbbls)		Equivalent (Mboe)

Summary Historical Reserve and Operating Data of Felix

The estimates of Felix's net proved reserves as of December 31, 2018 are based on a reserve report prepared by Netherland, Sewell & Associates, Inc., Felix's independent reserve engineers. You should refer to the reserve reports of Felix Energy Investment II, LLC, incorporated by reference herein when evaluating that materials presented below.

	Year Ended December 31, 2018

Estimated Proved Reserves¹
Oil (MBbls)		438,670
Natural gas (MMcf)		333,383
NGLs (MBbls)		83,541

Total (Mboe)		577,775

Proved developed (Mboe)		87,388
Proved undeveloped (Mboe)²		490,387

Total (Mboe)		577,775

PV-10 (in millions)³	$	6,328

¹: Proved reserves were calculated using prices equal to the twelve-month unweighted arithmetic average of the first-day-of-the-month prices for the prior twelve months. The prices used for each respective reserve report, after consideration for price differentials, are as follows: December 31, 2018—$61.25 per Bbl of oil, $2.177 per Mcf of natural gas, $29.46 per Bbl of NGLs.
²: As of December 31, 2018, Felix had 440 proved undeveloped locations based on a seven development drilling rig plan in place at such time. Felix has since reduced its drilling rigs from seven to five and as a result, Felix's proved undeveloped locations as of December 31, 2019 may be less compared to its proved undeveloped locations on December 31, 2018. In addition, the proved undeveloped reserves of Felix are based on Felix's development plans and may not necessarily reflect our development. Therefore, upon closing of the Acquisition, the proved undeveloped reserves booked by us may differ.
³: The PV-10 is not a GAAP financial measure and is derived from the standardized measure of discounted future net cash flows, which is the most directly comparable GAAP financial measure. PV-10 is a computation of the standardized measure of discounted future net cash flows on a pre-tax basis. PV-10 is equal to the standardized measure of discounted future net cash flows at the applicable date, before deducting future income taxes, discounted at 10 percent. At December 31, 2018, the PV-10 of Felix totaled $6,328 million. Felix's total standardized measure of discounted future cash flows as of December 31, 2018 was the same as Felix's PV-10 because Felix was not subject to entity-level taxation during the periods presented except for the Texas margin tax.

Before you decide to invest in the notes, you should consider the factors set forth below as well as the risk factors specific to our business and that may also affect Felix as well as the combined business after the completion of the Acquisition as set forth in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018, which is incorporated by reference in this prospectus supplement and the accompanying base prospectus and the other documents incorporated by reference. See "Where You Can Find Additional Information; Incorporation of Certain Documents by Reference." While we believe we have identified and discussed below the material risks affecting our business and the combined business after the completion of the Acquisition, there may be additional risks and uncertainties that we do not presently know or that we do not currently believe to be material that may adversely affect the business, financial condition and results of operations in the future of us and/or Felix.

The consummation of the Acquisition is subject to certain conditions, including the receipt of stockholder and regulatory approval which may or may not be obtained. If the conditions to the consummation of the Acquisition are not satisfied, or if the Purchase Agreement is terminated prior to closing, the Acquisition will not be consummated. If the Acquisition is not consummated on or before the Outside Date, or if we deliver a termination notice to the Escrow Agent indicating that we will not pursue the consummation of the Acquisition or have determined in our sole discretion that the Escrow Release Condition cannot or is not reasonably likely to be satisfied prior to the Outside Date, we will be required to redeem all of the outstanding notes at a redemption price equal to 100% of the initial issue price of the notes, plus accrued and unpaid interest to, but not including, the date of redemption. See "—Risk Factors Relating to the Notes—In the event that the Acquisition is not consummated on or prior to the Outside Date or we have determined in our sole discretion that the Escrow Release Condition cannot or is not reasonably likely to be satisfied prior thereto, the notes will be subject to a special mandatory redemption, and, as a result, you may not obtain the return you expect on the notes." Furthermore, the parties to the Purchase Agreement could amend the Purchase Agreement without any consent of the holders of the notes offered hereby, and such amendments could materially change the terms of the Purchase Agreement or otherwise result in less favorable terms for us.

We will incur significant transaction and acquisition-related costs in connection with the Acquisition.

We expect to incur significant costs associated with the Acquisition and combining the operations of the two companies, including costs to achieve targeted cost-savings. The substantial majority of the expenses resulting from the Acquisition will be composed of transaction costs related to the Acquisition, systems consolidation costs, and business integration related costs. We may also incur transaction fees and costs related to formulating integration plans. Additional unanticipated costs may be incurred in the integration of the two companies' businesses. Although we expect that the elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the businesses, should allow us to offset incremental transaction and acquisition-related costs over time, this net benefit may not be achieved in the near term, or at all.

Completion of the Acquisition may trigger change in control or other provisions in certain agreements to which Felix is a party, which may have an adverse impact on the combined company's business and results of operations.

The completion of the Acquisition may trigger change in control and other provisions in certain agreements to which Felix is a party. For those agreements for which we and Felix are unable to negotiate waivers of those provisions, the counterparties may exercise their rights and remedies under

the agreements, potentially terminating the agreements or seeking monetary damages. The foregoing or similar developments may have an adverse impact on the combined company's business and results of operations.

The integration of Felix may not be as successful as anticipated, and we may not achieve the intended benefits or do so within the intended timeframe.

The Acquisition involves numerous operational, strategic, financial, accounting, legal, tax and other risks, including potential liabilities associated with the acquired business. Difficulties in integrating Felix and the our ability to manage the combined company, may result in the combined company performing differently than expected, in operational challenges or in the delay or failure to realize anticipated expense-related efficiencies, and could have an adverse effect on our financial condition, results of operations or cash flows. Potential difficulties that may be encountered in the integration process include, among other factors:

Additionally, the success of the Acquisition will depend, in part, on our ability to realize the anticipated benefits and cost savings from combining Felix's and the Company's businesses, including operational and other synergies that we believe the combined company will achieve. The anticipated benefits and cost savings of the Acquisition may not be realized fully or at all, may take longer to realize than expected or could have other adverse effects that the Company does not currently foresee. Some of the assumptions that we have made, such as the achievement of operating synergies, may not be realized.

Our results may suffer if we do not effectively manage our expanded operations following the Acquisition.

Following completion of the Acquisition, the size of our business will increase significantly beyond its current size. Our future success will depend, in part, on our ability to manage this expanded

business, which poses numerous risks and uncertainties, including the need to integrate the operations and business of Felix into our existing business in an efficient and timely manner, to combine systems and management controls and to integrate relationships with customers, vendors and business partners. Failure to successfully manage the combined company may have an adverse effect on our financial condition, results of operations or cash flows.

Felix Parent will have significant influence over us after completion of the Acquisition.

Upon completion of the Acquisition, Felix Parent will beneficially own approximately 27% of our common stock. As long as Felix Parent owns or controls a significant percentage of our outstanding voting power, it will have the ability to significantly influence corporate actions requiring stockholder approval, including the election and removal of directors and the size of our board of directors, any amendment to our certificate of incorporation or bylaws, or the approval of any merger or other significant corporate transaction, including a sale of substantially all of our assets. Felix Parent's influence over the combined company management could have the effect of delaying or preventing a change in control or otherwise discouraging a potential acquirer from attempting to obtain control of the combined company, which could cause the market price of our common stock to decline or prevent stockholders from realizing a premium over the market price for our common stock.

Pursuant to the Stockholders' Agreement to be entered into upon closing of the Acquisition, Felix Parent will have the right to nominate up to two directors to the combined company's board of directors. Felix Parent's right to designate directors to the combined company's board of directors is subject to their ownership percentage of the total outstanding shares of our common stock. If Felix Parent holds: (i) 20% or greater of the outstanding common stock, they will have the right to appoint two directors or (ii) greater than 10% but less than 20% of the outstanding common stock, they will have the right to appoint one director.

Felix Parent's interests may not align with our interests or the interests of our other stockholders.

Following the completion of the Acquisition, we may incorporate Felix's hedging activities into its business, and we may be exposed to additional commodity price risks arising from such hedges.

To mitigate its exposure to changes in commodity prices, Felix hedges oil, natural gas liquids and natural gas prices from time to time, primarily through the use of certain derivative commodity instruments. If we assume existing Felix hedges, we will bear the economic impact of all of Felix's current hedges following the completion of the Acquisition. Actual crude oil, natural gas and natural gas liquids prices may differ from the combined company's expectations and, as a result, such hedges could have a negative impact on our business.

The unaudited pro forma financial information included in this prospectus supplement may not be representative of our results as a combined company if the Acquisition is consummated, and accordingly, you have limited financial information on which to evaluate the financial performance of the combined company and your investment decision.

We and Felix currently operate as separate companies. We have had no prior history as a combined entity and our operations have not previously been managed on a combined basis. The pro forma financial information is presented for informational purposes only and is not necessarily indicative of the financial position or results of operations that would have actually occurred had the Acquisition been completed at or as of the dates indicated, nor is it indicative of the future operating results or financial position of the combined company. The pro forma financial statement of earnings does not reflect future nonrecurring charges resulting from the Acquisition. The unaudited pro forma financial information does not reflect future events that may occur after the Acquisition, including the potential realization of operating cost savings (synergies) or restructuring activities or other costs

related to the planned integration of Felix, and does not consider potential impacts of current market conditions on revenues or expenses. The pro forma financial information included in this prospectus supplement has been derived from our and Felix's historical consolidated financial statements and certain adjustments and assumptions have been made regarding the combined organization after giving effect to the transaction. The assets and liabilities of us and Felix have been measured at fair value based on various preliminary estimates using assumptions that management believes are reasonable utilizing information currently available. The process for estimating the fair value of acquired assets and assumed liabilities requires the use of judgment in determining the appropriate assumptions and estimates. These estimates may be revised as additional information becomes available and as additional analyses are performed. Differences between preliminary estimates in the pro forma financial information and the final acquisition accounting will occur and could have a material impact on the pro forma financial information and the combined organization's financial position and future results of operations.

In addition, the assumptions used in preparing the pro forma financial information may not prove to be accurate, and other factors may affect our financial condition or results of operations following the completion of the Acquisition.

Our indebtedness could impair our financial condition and our ability to fulfill our debt obligations, including our obligations under the notes.

As of September 30, 2019, on a pro forma as adjusted basis, after giving effect to the Acquisition, the Felix Disposition, this offering (including the application of proceeds therefrom) and borrowings under our Credit Facility to fund transaction costs related to this offering and the Acquisition, we would have had total indebtedness of $3,171 million (excluding $37 million of outstanding letters of credit issued under the Credit Facility) and an additional $1,421 million available for borrowing under our Credit Facility (after giving effect to $37 million of outstanding letters of credit issued under the Credit Facility). At the time of the Acquisition closing, the Company may elect to use cash on hand to fund the estimated $42 million in transaction costs of this offering and the Acquisition rather than borrowings under the Credit Facility to fund such costs.

Our debt service obligations and restrictive covenants in our Credit Facility, the indenture governing our existing notes and the indenture governing the notes offered hereby could have important consequences to you. For example, they could:

Additionally, we may be able to incur substantial additional indebtedness in addition to the notes. Although our Credit Facility contains restrictions on the incurrence of additional indebtedness by our subsidiaries, such restrictions are subject to a number of qualifications and exceptions, and indebtedness incurred in compliance with such restrictions could be substantial. To the extent that new indebtedness is added to our current debt levels, the negative consequences listed above may be exacerbated and could adversely affect our ability to pay the interest on, and principal of, the notes.

We have a holding company structure in which our subsidiaries conduct our operations and own our operating assets, which may affect our ability to make payments on the notes.

We have a holding company structure, and our subsidiaries conduct all of our operations and own all of our operating assets. Further, substantially all of our cash flows are generated by the subsidiaries that are guarantors under our Credit Facility. We have no significant assets other than the ownership interests in these subsidiaries. As a result, our ability to make required payments on the notes depends on the performance of our subsidiaries and their ability to distribute funds to us. The ability of our subsidiaries to make distributions to us may be restricted by, among other things, applicable state partnership and limited liability company laws and other laws and regulations. In addition, our subsidiaries are not prohibited by the terms of their respective organizational documents or the notes from incurring indebtedness, and the agreements governing such indebtedness may contain restrictions on the ability of our subsidiaries to make distributions to us. The notes will be structurally subordinated to all existing and future indebtedness and other liabilities of our subsidiaries. Moreover, if our subsidiaries were to incur significant amounts of indebtedness, such occurrence may inhibit their operating results, cash flow, and financial condition, and their ability to make distributions to us could suffer. An inability by our subsidiaries to make distributions to us would materially and adversely affect our ability to pay interest on, and the principal of, the notes because we expect distributions we receive from our subsidiaries to represent a significant portion of the cash we use to pay interest on, and the principal of, the notes. If we are unable to obtain the funds necessary to pay the principal amount at maturity of the notes, we may be required to adopt one or more alternatives, such as a refinancing of the notes. We cannot assure you that we would be able to refinance the notes.

Our debt agreements impose restrictions on us that may limit our access to credit and adversely affect our ability to operate our business.

Our Credit Facility contains various covenants that restrict or limit, among other things, our ability to grant liens, merge or sell substantially all of our assets, make investments, guarantees, loans or advances in non-subsidiaries, enter into certain hedging agreements, incur additional debt at subsidiaries and enter into certain affiliate transactions. In addition, our Credit Facility contains financial covenants, including an additional financial covenant if our credit ratings are below a specified level, and other limitations with which we will need to comply and which may limit our ability to borrow under the facility. Similarly, the indentures governing our existing notes and the notes offered hereby restrict our ability to grant liens to secure certain types of indebtedness and merge or sell substantially all of our assets. These covenants could adversely affect our ability to finance our future operations or capital needs or engage in, expand or pursue our business activities and prevent us from engaging in certain transactions that might otherwise be considered beneficial to us. Our ability to

comply with these covenants may be affected by events beyond our control, including prevailing economic, financial and industry conditions. If market or other economic conditions deteriorate, our current assumptions about future economic conditions turn out to be incorrect or unexpected events occur, our ability to comply with these covenants may be significantly impaired.

Our failure to comply with the covenants in our debt agreements could result in events of default. Upon the occurrence of such an event of default, the lenders could elect to declare all amounts outstanding under our Credit Facility to be immediately due and payable and terminate all commitments, if any, to extend further credit. Certain payment defaults or an acceleration under one debt agreement could cause a cross-default or cross-acceleration of another debt agreement. Such a cross-default or cross-acceleration could have a wider impact on our liquidity than might otherwise arise from a default or acceleration of a single debt instrument. If an event of default occurs, or if other debt agreements cross-default, and the lenders under the affected debt agreements accelerate the maturity of any loans or other debt outstanding to us, we may not have sufficient liquidity to repay amounts outstanding under such debt agreements. The notes do not contain a cross-acceleration event of default. See "Description of Notes" and "Description of Debt Securities" in the accompanying base prospectus.

Our ability to repay, extend or refinance our debt obligations and to obtain future credit will depend primarily on our operating performance, which will be affected by general economic, financial, competitive, legislative, regulatory, business and other factors, many of which are beyond our control. Our ability to refinance our debt obligations or obtain future credit will also depend upon the current conditions in the credit markets and the availability of credit generally. If we are unable to meet our debt service obligations or obtain future credit on favorable terms, if at all, we could be forced to restructure or refinance our indebtedness, seek additional equity capital or sell assets. We may be unable to obtain financing or sell assets on satisfactory terms, or at all.

The notes will be effectively subordinated to any of our secured indebtedness to the extent of the assets securing such indebtedness and structurally subordinated to liabilities and indebtedness of our subsidiaries.

Pursuant to our $1.5 billion Credit Facility, we may incur secured indebtedness and grant security interests in our properties and assets in the future. As of September 30, 2019, on a pro forma basis, after giving effect to the Acquisition and this offering, (i) we would have had total indebtedness of $3,171 million, none of which was subordinated and $42 million of which was secured borrowings under our Credit Facility to fund transaction costs related to this offering and the Acquisition (excluding $37 million of outstanding letters of credit issued under the Credit Facility) and (ii) we would have $1,421 million available for additional borrowing under our Credit Facility (after giving effect to $37 million of outstanding letters of credit issued under the Credit Facility). At the time of the Acquisition closing, the Company may elect to use cash on hand to fund the estimated $42 million in borrowings related to the transaction costs of this offering and the Acquisition rather than such borrowings under the Credit Facility.

Any holders of any secured indebtedness that we have or may incur in the future would have claims with respect to our assets constituting collateral for such indebtedness that are effectively prior to your claims under the notes. In the event of a default on such secured indebtedness or our bankruptcy, liquidation or reorganization, those assets would be available to satisfy obligations with respect to the indebtedness secured thereby before any payment could be made on the notes. Accordingly, any such secured indebtedness would effectively be senior to the notes to the extent of the value of the collateral securing the indebtedness. While the indentures governing our existing notes and the notes offered hereby place some limitations on our ability to create liens, there are significant exceptions to these limitations that will allow us to secure some kinds of indebtedness without equally and ratably securing the notes. To the extent the value of the collateral is not sufficient to satisfy the

secured indebtedness, the holders of that indebtedness would be entitled to share with the holders of the notes and the holders of other claims against us with respect to our other assets. Holders of the notes will participate ratably with all holders of our unsecured indebtedness that is deemed to be of the same class as the notes, and potentially with all of our other general creditors, based upon the respective amounts owed to each holder or creditor, in our remaining assets. In any of the foregoing events, we cannot assure you that there will be sufficient assets to pay amounts due on the notes. As a result, holders of notes may receive less than holders of secured indebtedness.

In addition, the notes are not guaranteed by our subsidiaries and our subsidiaries are generally not prohibited under the indentures governing our existing notes or the notes offered hereby from incurring additional indebtedness. Our subsidiaries are operating entities with substantial liabilities arising in the ordinary course of business. In addition, certain of our subsidiaries are guarantors under our Credit Facility. Substantially all of our cash flows are generated by the subsidiaries that are guarantors under our Credit Facility. As a result, holders of the notes will be structurally subordinated to claims of third-party creditors, including holders of indebtedness and other liabilities, of these subsidiaries. Claims of those other creditors, including trade creditors, secured creditors, governmental authorities and holders of indebtedness or guarantees issued by the subsidiaries, will generally have priority as to the assets of the subsidiaries over claims by the holders of the notes. As a result, rights of payment of holders of our indebtedness, including the holders of the notes, will be structurally subordinated to all those claims of creditors of our subsidiaries.

In the event that the Acquisition is not consummated on or prior to the Outside Date or we have determined in our sole discretion that the Escrow Release Condition cannot or is not reasonably likely to be satisfied prior thereto, the notes will be subject to a special mandatory redemption, and, as a result, you may not obtain the return you expect on the notes.

If the Acquisition is not consummated on or before the Outside Date, or if we deliver a termination notice to the Escrow Agent indicating that we will not pursue the consummation of the Acquisition or have determined in our sole discretion that the Escrow Release Condition cannot or is not reasonably likely to be satisfied prior to the Outside Date, we will be required to redeem all of the outstanding notes at a redemption price equal to 100% of the initial issue price of the notes, plus accrued and unpaid interest, if any, to, but not including the date of redemption. See "Description of Notes—Escrow of Proceeds; Special Mandatory Redemption." We cannot assure you that we will have sufficient funds available to redeem the notes in full. In addition, even if we are able to redeem the notes pursuant to the mandatory redemption provision, you may not be able to reinvest the proceeds you receive from the redemption in a comparable security at an effective interest rate or return on investment as high as what you otherwise would have received on your notes.

In addition, we will not be required to redeem the notes as long as the Acquisition closes prior to the Outside Date, even if between the closing of this offering and the closing of the Acquisition we experience any changes (including any material changes) in our business or financial condition, or if the terms of the Purchase Agreement are amended, including in material respects.

We may be unable to fund the entire Special Mandatory Redemption Price relating to the notes in the event of a special mandatory redemption.

The gross proceeds from this offering will be deposited into the escrow account. Until such time as it is released from escrow, the Escrow Property will be held in an account under the control of the Escrow Agent and will be invested by the Escrow Agent at our instruction in U.S. Treasury securities and certain other permitted investments as directed by us. See "Description of Notes—Escrow of Proceeds; Special Mandatory Redemption." In the event of a special mandatory redemption, the Escrow Property will be released to the trustee and we will be required to provide to the trustee any additional amounts necessary to fund the redemption of the notes at the Special Mandatory

Redemption Price. We may not have sufficient funds in addition to the Escrow Property to pay the entire Special Mandatory Redemption Price, which would constitute an event of default under the indenture that will govern the notes and could result in defaults under our other debt agreements and have material adverse consequences for us and the holders of the notes.

If a bankruptcy or reorganization case is commenced, bankruptcy laws may prevent the release of the Escrow Property.

If we commence a bankruptcy or reorganization case, or one is commenced against us, while amounts remain in the escrow account described under "Description of Notes—Escrow of Proceeds; Special Mandatory Redemption," applicable bankruptcy laws may prevent the Escrow Agent from releasing the funds in the escrow account or applying those funds to effect a special mandatory redemption, as applicable, of the notes or otherwise applying those funds for the benefit of the holders of the notes. The court adjudicating that case might find that such escrow account is the property of the bankruptcy estate, with or without restrictions on the use of such funds by the bankruptcy estate. In addition, the notes will not be secured by any lien over the funds in the escrow account and therefore the holders of the notes will be unsecured creditors of the bankruptcy estate. As a result, holders of the notes may not be able to have the funds in the escrow account applied at the time or in the manner contemplated by the indenture governing the notes and could suffer a loss.

We may not be able to repurchase the notes upon a Change of Control Triggering Event.

Upon a change of control of us and a downgrade of the rating of a series of notes (or if the notes have an investment grade rating at the time of the change of control, such notes are downgraded below an investment grade rating by Moody's Investors Service Inc. and Standard & Poor's Ratings Services), as a result of such change of control, we will be required to make an offer to each holder of such series of notes to repurchase all or any part of such holder's notes at a price equal to 101% of their principal amount, plus accrued and unpaid interest, if any, to the date of purchase. See "Description of Notes—Change of Control." If such events were to occur, we cannot assure you that we will have the financial resources to purchase your new notes, particularly if such events trigger a similar repurchase requirement for, or result in the acceleration of, other existing or future indebtedness. In addition, our ability to repurchase the notes may be limited by law and regulations or the terms of other agreements relating to our indebtedness outstanding at the time. Any failure to purchase the notes as required under the indenture governing the notes would result in a default under the indenture, which could have material adverse consequences for us and the holders of the notes.

Our credit ratings may not reflect all risks of your investment in the notes.

The credit ratings assigned to a series of notes are not a recommendation to buy, sell or hold such series of notes and do not address all material risks relating to an investment in the notes, but rather reflect only the view of each rating agency at the time the rating is issued. We cannot assure you that these credit ratings will remain in effect for any given period of time or that a rating will not be lowered, suspended or withdrawn entirely by the applicable rating agencies. An increase in the level of our outstanding indebtedness, or other events that could have an adverse impact on our business, properties, financial condition, results of operations or prospects, may cause the rating agencies to downgrade our debt credit rating generally and the ratings on the notes. Each agency's rating should be evaluated independently of any other agency's rating. Actual or anticipated changes or downgrades in our credit ratings, including any announcement that our ratings are under further review for a downgrade, could affect the trading price for or liquidity of the notes, increase our corporate borrowing costs, limit our access to the capital markets or result in more restrictive covenants in future debt agreements.

The limited covenants applicable to the notes may not provide protection against some events or developments that may affect our ability to repay the notes or the trading prices for the notes.

In addition, the indenture governing the notes allows us to incur (a) an unlimited amount of debt to develop oil, gas, coal or other mineral or timber properties secured by liens on such properties and (b) an unlimited amount of debt to finance advance payments under any contract for oil, natural gas, hydrocarbon or other mineral exploration or development secured by liens on such contracts.

As a result, you should consider the limited covenants in the indenture governing the notes as a significant factor in evaluating whether to invest in the notes.

There may not be a liquid market for the notes and, if a market does develop, it may not be maintained.

Each series of notes is a new issue of securities for which there is currently no established trading market. The underwriters have advised us that they intend to make a market for each series of notes, but they are not obligated to do so and may discontinue market-making activities at any time. Accordingly, there can be no assurance that a liquid market for any series of notes will develop or be maintained. We do not intend to apply for the notes to be listed on any securities exchange or to arrange for any quotation system to quote them.

The market price of each series of notes will depend on many factors that may vary over time and some of which are beyond our control, including but not limited to:

As a result of these factors, you may only be able to sell your notes at a price below what you believe to be appropriate, including a price below the price you paid for them.

We estimate that the net proceeds from this offering, after deducting underwriting discounts and commissions and estimated offering expenses, will be approximately $ million. The gross proceeds from this offering will be deposited into the escrow account. Upon release from escrow if the Escrow Release Condition has been satisfied we intend to use the net proceeds of this offering to finance a portion of the cash consideration for the Acquisition, including repayment of any remaining amounts outstanding under the Felix Debt Facilities, and to pay related fees and expenses.

$1,421 million available for additional borrowing under our Credit Facility (after giving effect to $37 million of outstanding letters of credit issued under the Credit Facility). The Company draws from the Credit Facility for general corporate purposes from time to time. The borrowings under the Credit Facility are to pay the transaction costs of this offering and the Acquisition. At the time of the Acquisition closing, the Company may elect to use cash on hand rather than such borrowings under the Credit Facility to fund such costs.

WPX Energy, Inc.
Notes to Pro Forma Condensed Combined Financial Statements
(Unaudited)

In connection with the Acquisition, Felix has represented to the Company that is will either (i) distribute its crude midstream business and water business to Felix Parent in connection with the Acquisition, or (ii) dispose of such assets in a third party sale. We refer to either the distribution or sale of such assets herein as the "Felix Dispositions." The pro forma balance sheet assumes the probable distribution of these assets and certain related liabilities to a Felix Parent. In either case, WPX would acquire Felix exclusive of these assets, however, contracts utilizing the services of these businesses will remain in place.

The Acquisition will be accounted for using the acquisition method of accounting for business combinations. The allocation of the preliminary estimated purchase price is based upon management's estimates of and assumptions related to the fair value of assets to be acquired and liabilities to be assumed as of September 30, 2019 using currently available information. Due to the fact that the unaudited pro forma combined financial information has been prepared based on these preliminary estimates, the final purchase price allocation and the resulting effect on financial position and results of operations may materially differ from the pro forma amounts included herein. The Company expects to finalize its allocation of the purchase consideration as soon as practicable after completion of the Acquisition but is not required to finalize for one year from the closing date of the Acquisition. For income tax purposes, the Acquisition will be treated as an asset purchase such that the tax bases in the assets and liabilities will generally reflect the allocated fair value at closing. Therefore, we do not anticipate a material difference in the initial financial and tax bases of the assets and liabilities and have not reflected any deferred income taxes related to the Acquisition.

The preliminary purchase price allocation is subject to change due to several factors, including but not limited to:

The preliminary consideration to be transferred and fair value of assets acquired and liabilities assumed are as follows:

Allocation	Preliminary Purchase Price

	(Millions)
Consideration:
Cash	$	900
Fair value of WPX common stock to be issued¹		2,031

Total consideration	$	2,931



Fair value of liabilities assumed:
Accounts payable	$	120
Accrued liabilities		20
Asset retirement obligation		3

Total liabilities assumed as of September 30, 2019	$	143



Fair value of assets acquired:
Cash and cash equivalents		4
Accounts receivable, net		71
Derivative assets, current		10
Inventories		2
Other current assets		6
Properties and equipment, net		2,980
Other noncurrent assets		1

Total assets acquired as of September 30, 2019	$	3,074

Based on the closing stock price on December 31, 2019, the preliminary value of WPX's equity consideration to be transferred was approximately $2.0 billion. The final value of WPX consideration will be determined based on the actual number of WPX shares issued and the market price of WPX's common stock on the closing date of the Acquisition. A ten percent increase or decrease in the closing price of WPX's common stock, as compared to December 31, 2019 closing price of $13.74, would increase or decrease the purchase price by approximately $203 million, assuming all other factors are held constant.

The following adjustments have been made to the accompanying unaudited pro forma combined balance sheet as of September 30, 2019 to reflect the acquisition adjustments related to the Acquisition:

The following adjustments have been made to the accompanying unaudited pro forma combined balance sheet to reflect the Financing Transactions:

The amounts presented are primarily adjustments necessary to reflect the removal of the results of operations of Felix's midstream business and water business from Felix's consolidated historical financial statements. Additionally, lease and facility operating expenses and gathering, processing and transportation expenses were adjusted to reflect intercompany contracts with the water and midstream businesses, respectively, that were previously eliminated.

The following adjustments have been made to the accompanying unaudited pro forma combined statements of operations to reflect the acquisition transactions related to the Acquisition:

The following adjustments have been made to the accompanying unaudited pro forma combined statements of operations to reflect the financing transactions related to the Acquisition:

We currently have outstanding approximately $73 million aggregate principal amount of 6.00% Senior Notes due 2022 (the "2022 Notes"), $406 million aggregate principal amount of 8.25% Senior Notes due 2023 (the "2023 Notes"), $650 million aggregate principal amount of 5.250% Senior Notes due 2024 (the "2024 Notes"), $500 million aggregate principal amount of 5.750% Senior Notes due 2026 (the "2026 Notes,") and $600 million aggregate principal amount of 5.250% Senior Notes due 2027 (the "2027 Notes" and collectively, the "Existing Notes"). The Existing Notes were issued under indentures between us and The Bank of New York Mellon Trust Company, N.A., as trustee.

Optional Redemption. We have the option prior to October 15, 2021 for the 2022 Notes, June 1, 2023 for the 2023 Notes, June 15, 2024 for the 2024 Notes, June 1, 2021 for the 2026 Notes and October 15, 2022 for the 2027 Notes to redeem some or all of such notes at a specified "make whole" premium as described in the indenture governing the applicable series of Existing Notes to be redeemed. We also have the option at any time or from time to time on or after October 15, 2021 to redeem the 2022 Notes, on or after June 1, 2023 to redeem the 2023 Notes, on or after June 15, 2024 to redeem the 2024 Notes, on or after June 1, 2021 to redeem the 2026 Notes or on or after October 15, 2022 to redeem the 2027 Notes in whole or in part, at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest thereon to the redemption date.

Change of Control. If we experience a change of control (as defined in the indentures governing the notes) accompanied by a specified rating decline, we must offer to repurchase the Existing Notes of such series at 101% of their principal amount, plus accrued and unpaid interest, if any.

Covenants. The terms of the indentures governing our Existing Notes restrict our ability and the ability of our subsidiaries to incur additional indebtedness secured by liens and our ability to effect a consolidation, merger or sale of substantially all our assets and the assets of our subsidiaries. The indentures also require us to file with the trustee and the SEC certain documents and reports within certain time limits set forth in the indentures. However, these limitations and requirements are subject to a number of important qualifications and exceptions. The indentures do not require the maintenance of any financial ratios or specified levels of net worth or liquidity.

Events of Default. Each of the following is an "Event of Default" under the indentures with respect to the Existing Notes of any series:

We have a senior secured revolving credit facility agreement with Wells Fargo Bank, National Association, as Administrative Agent, Lender and Swingline Lender and the other lenders party thereto providing for up to $1.5 billion of revolving loans. The Credit Facility has a maturity date of April 17, 2023, subject to a springing maturity on October 15, 2021 if the difference on such date between (a) the amount of aggregate commitments available to the Company under the Credit Facility plus unrestricted cash and cash equivalents of the Company and (b) the outstanding principal amounts owing under the 2022 Notes is less than $500 million. Based on our current credit ratings, a "Collateral Trigger Period" is currently in effect, making the Credit Facility subject to certain financial covenants and a Borrowing Base as described below. The Credit Facility may be used for working capital, acquisitions, capital expenditures and other general corporate purposes. The financial covenants in the Credit Facility may limit our ability to borrow money, depending on the applicable financial metrics at any given time. As of September 30, 2019, we had no outstanding borrowings and there were $37 million of letters of credit issued under the Credit Facility, and we were in compliance with our financial covenants under the credit agreement. Unused borrowing availability of up to $1,463 million was available as of September 30, 2019 (after giving effect to $37 million of outstanding letters of credit issued under the Credit Facility).

Borrowing Base. During a Collateral Trigger Period, loans under the Credit Facility are subject to a borrowing base as calculated in accordance with the provisions of the Credit Facility. As of March 18, 2016, the borrowing base was set at $1.025 billion. It was reaffirmed at $1.025 billion in October 2016, was increased to $1.2 billion in April 2017, was increased further to $1.5 billion in October 2017. On April 17, 2018, the Borrowing Base was increased to $1.8 billion, which was in excess of commitments, which were also increased to $1.5 billion. On April 22, 2019, the Borrowing Base was increased to $2.1 billion. At this time, the Credit Facility Agreement is limited by the total commitments, which remain at $1.5 billion. The Borrowing Base will remain in effect until the next redetermination date as set forth in the Credit Facility. The borrowing base is recalculated at least every six months per the terms of the Credit Facility provided, however, that the Company may, if certain conditions are met, elect during any Collateral Trigger Period that scheduled redeterminations of the Borrowing Base be made annually on April 1 instead of semi-annually. The Company has entered into a consent letter agreement with the Administrative Agent and certain Lenders party to the Credit Facility effective as of January 7, 2020 (the "Consent Letter"). The Consent Letter waives the automatic borrowing base reduction which would otherwise occur under the Credit Facility at the time of the issuance of the Notes.

Terms and Conditions. The Credit Facility is currently guaranteed by certain subsidiaries of the Company (excluding subsidiaries holding midstream assets and subsidiaries meeting other exclusionary criteria), as Guarantors, and secured by substantially all of the Company's and the Guarantors' assets (including oil and gas properties), subject to customary exceptions and carve outs (which includes the exclusion of, among other things, midstream assets and the equity interests of subsidiaries holding midstream assets). The obligation to secure and/or guaranty the obligations terminates on the earlier of any applicable Collateral Trigger Termination Date (as described below) or the date on which all liens held by the Administrative Agent for the benefit of the secured parties are released pursuant to the terms of the Credit Facility.

The Collateral Trigger Termination Date is the first date on which (i) the Company's Corporate Rating is BBB– or better by S&P (without negative outlook or negative watch) or (ii) Baa3 or better by Moody's (without negative outlook or negative watch), provided that the other of the two Corporate Ratings is at least BB+ by S&P or Ba1 by Moody's.

Following the Collateral Trigger Termination Date, a Collateral Trigger Period may again occur if the Company's Corporate Rating is BB– or lower (or unrated) by S&P or Ba3 or lower (or unrated) by Moody's or upon the Company's election to voluntarily enter into a Collateral Trigger Period.

Interest and Commitment Fees. Interest on borrowings under the Credit Facility is payable at rates per annum equal to, at the Company's option: (1) a fluctuating base rate equal to the alternate base rate plus the applicable margin, or (2) a periodic fixed rate equal to LIBOR plus the applicable margin. The alternate base rate will be the highest of (i) the federal funds rate plus 0.5 percent, (ii) the Prime Rate, and (iii) one-month LIBOR plus 1.0 percent. The Company is required to pay a commitment fee based on the unused portion of the commitments under the Credit Facility. During a Collateral Trigger Period, the applicable margin ranges from 1.25% to 2.25% per annum and the commitment fee ranges from 0.375% to 0.500% per annum. The applicable margin and the commitment fees during a Collateral Trigger Period are determined by reference to a utilization percentage as set forth in the Credit Facility. The applicable margin and the commitment fee other than during a Collateral Trigger Period are determined by reference to a pricing schedule based on the Company's senior unsecured non-credit enhanced debt ratings.

Currently, while a Collateral Trigger Period Exists, the Company is required to maintain:

If a Collateral Trigger Termination Date occurs, other financial covenants would apply.

Covenants. The Credit Facility contains customary representations and warranties and affirmative, negative and financial covenants (as described above) which were made only for the purposes of the Credit Facility and as of the specific date (or dates) set forth therein, and may be subject to certain limitations as agreed upon by the contracting parties. The covenants limit, among other things, our ability and the ability of our subsidiaries to incur indebtedness; our ability and the ability of our subsidiaries to grant certain liens, make restricted payments, materially change the nature of our or their business, make investments, guarantees, loans or advances in non-subsidiaries or enter into certain hedging agreements; the ability of our material subsidiaries to enter into certain restrictive agreements; our ability and the ability of our material subsidiaries to enter into certain affiliate transactions; our the ability and the ability of our subsidiaries to redeem any senior notes; and our ability to merge or consolidate with any person or sell all or substantially all of our assets to any person. We and our subsidiaries are also prohibited from using the proceeds under the Credit Facility in violation of Sanctions (as defined in the Credit Facility). In addition, the representations, warranties and covenants contained in the Credit Facility are subject to certain exceptions and/or standards of materiality applicable to the contracting parties.

Events of Default. The Credit Facility includes customary events of default, including events of default relating to:

If an event of default occurs under the Credit Facility, the lenders will be able to terminate the commitments and accelerate the maturity of the loans under the Credit Facility and exercise other rights and remedies.

As of September 30, 2019, Felix Parent had $300.0 million aggregate principal amount of notes outstanding under the Felix Parent Notes Facility. The Felix Parent Notes Facility is secured by a lien on the equity of Felix and certain of Felix's assets. As a condition to and simultaneous with the closing of the Acquisition, all remaining amounts outstanding under the Felix Parent Notes Facility are to be repaid in order to cause the release of such liens and terminate the facility. Any amounts outstanding under the Felix Parent Notes Facility that are repaid from the Unadjusted Cash Purchase Price in connection with and simultaneous with the closing of the Acquisition will result in a reduction in the Unadjusted Cash Purchase Price received by Felix Parent. Furthermore, in connection with entering into the Purchase Agreement, Felix Parent received commitments from certain of its affiliates to finance the repayment of any amounts outstanding under the Felix Debt Facilities to the extent such amounts outstanding exceed the Unadjusted Cash Purchase Price subject to certain adjustments. We also expect Felix Parent to apply the proceeds from the Felix Dispositions to pay down indebtedness under the Felix Debt Facilities.

Felix has a $1.125 billion secured revolving reserve-based credit facility with JPMorgan Chase Bank, N.A., as administrative agent and other lenders party thereto. The Felix Revolving Credit Facility provides for borrowings and letters of credit on a revolving basis. As of September 30, 2019, the borrowing base was $1,125 million and is determined based on a periodic valuation of Felix's oil and natural gas reserves, subject to certain adjustments. The redetermination dates are set on or about each May 1 and November 1. No principal payments, other than in the event current loans and letters of credit outstanding under the Felix Revolving Credit Facility exceed amounts available thereunder, are required under the Felix Revolving Credit Facility until the maturity of the Felix Revolving Credit Facility to occur on July 1, 2021.

As of September 30, 2019, Felix had $788 million outstanding under the Felix Revolving Credit Facility and an applicable interest rate of 4.5%. As a condition to and simultaneous with the closing of the Acquisition, all remaining amounts outstanding under the Felix Revolving Credit Facility are to be repaid in order to cause the release of liens on certain of Felix's assets and terminate the facility. Any outstanding amounts under the Felix Revolving Credit Facility that are repaid from the Unadjusted Cash Purchase Price in connection with and simultaneous with the closing of the Acquisition will result in a reduction in the Unadjusted Cash Purchase Price received by Felix Parent. As described above, we expect Felix Parent to apply the proceeds from the Felix Dispositions to pay down indebtedness under the Felix Debt Facilities and Felix Parent has received commitments from certain of its affiliates to finance the repayment of any amounts outstanding under the Felix Debt Facilities to the extent such amounts exceed the Unadjusted Cash Purchase Price subject to certain adjustments.

You can find the definitions of certain terms used in this description under the subheading "—Certain Definitions." In this description, the terms "WPX," "we," "us," and "our" refer only to WPX Energy, Inc. and not to any of its Subsidiaries. You should read the following information in conjunction with the statements under "Description of Debt Securities" in the accompanying prospectus. This "Description of Notes" replaces the description of the general terms and provisions of the debt securities set forth in the accompanying prospectus to the extent the terms of the notes described below are inconsistent with the provisions of the debt securities set forth in the accompanying prospectus.

We will issue $ in aggregate principal amount of % senior notes due 2028 (the "2028 notes") and $ in aggregate principal amount of % senior notes due 2030 and (the "2030 notes" and together with the 2028 notes, the "notes") under an indenture dated as of September 8, 2014 (the "base indenture"), as supplemented by a supplemental indenture (the "supplemental indenture") between us and The Bank of New York Mellon Trust Company, N.A., as trustee (the "trustee"). The term "indenture" refers to the base indenture as supplemented by the supplemental indenture.

The terms of the notes include those stated in the indenture and those made part of the indenture by reference to the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). The following description is a summary of the material provisions of the indenture and the notes. It does not restate those agreements in their entirety. We urge you to read the indenture in its entirety because it, and not this description, defines your rights as holders of the notes. Copies of the indenture are available as set forth under "Where You Can Find Additional Information; Incorporation of Certain Documents by Reference." Certain defined terms used in this description but not defined below under "—Certain Definitions" have the meanings assigned to them in the indenture.

The registered holder of a note will be treated as the owner of it for all purposes. Only registered holders will have rights under the indenture.

As of September 30, 2019, on a pro forma as adjusted basis, after giving effect to the Acquisition and this offering (including the application of proceeds therefrom):

Substantially all of our cash flows are generated by the subsidiaries that are guarantors under our Credit Facility.

The indenture permits us to incur additional indebtedness, including additional senior unsecured indebtedness. The indenture also does not restrict the ability of our Subsidiaries to incur additional indebtedness. See "Risk Factors—Our indebtedness could impair our financial condition and our ability to fulfill our debt obligations, including our obligations under the notes" and "Risk Factors—The notes will be effectively subordinated to any of our secured indebtedness to the extent of the assets securing such indebtedness and structurally subordinated to liabilities and indebtedness of our subsidiaries."

We will issue the notes with an initial maximum aggregate principal amount of $900,000,000, consisting of $ aggregate principal amount of 2028 notes and $ aggregate principal amount of 2030 notes. The 2028 notes will mature on , 2028. The 2030 notes will mature on , 2030. We will issue the notes in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

Interest on the notes will accrue from , 2020 at a rate per annum of % in the case of the 2028 notes and at a rate per annum of % in the case of the 2030 notes, and will be payable semi-annually in arrears on and , beginning on , 2020. We will make each interest payment on the applicable series of notes to the holders of record at the close of business on the immediately preceding or (whether or not a Business Day). Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

We may, without the consent of the holders of any series of notes, issue additional notes having the same ranking and the same interest rate, maturity and other terms as such series of notes, except for the public offering price, the issue date and, if applicable, the initial interest payment date and initial interest accrual date. Any additional notes having such similar terms, together with such series of notes offered hereby, will constitute a single series of notes under the indenture; provided that if such additional notes are not fungible for U.S. federal income tax purposes with the notes of such series offered hereby, such additional notes shall be issued under a separate CUSIP number.

We will pay all principal, interest and premium, if any, on each series of notes in the manner described under "—Same Day Settlement and Payment" below.

The trustee will initially act as paying agent and registrar. We may change the paying agent or registrar without prior notice to the holders of each series of notes, and we or any of our Subsidiaries may act as paying agent or registrar.

A holder may transfer or exchange notes in accordance with the indenture. The registrar and the trustee may require a holder to furnish appropriate endorsements and transfer documents in

connection with a transfer of notes. No service charges will be imposed by us, the trustee or the registrar for any registration of transfer or exchange of notes, but holders may be required to pay all taxes due on transfer or exchange. We are not required to transfer or exchange any note selected for redemption, except the unredeemed portion of any note being redeemed in part. Also, we are not required to transfer or exchange any note for a period of 15 days before mailing notice of any redemption of notes.

Concurrently with the issuance of the notes, we will enter into an escrow agreement with Scotiabank & Trust (Cayman) Ltd., which will act as escrow agent (the "Escrow Agent"), pursuant to which we will deposit, or cause to be deposited, into an account under the control of the escrow agent (the "Escrow Account") the gross proceeds from the issuance of the notes (together with any other property from time to time held in the escrow account, the "Escrow Property"). As long as the Escrow Property is deposited with the Escrow Agent, it will be invested by the escrow agent at our instruction in U.S. Treasury securities and certain other permitted investments as directed by us. The notes will not be secured by any lien over the Escrow Property.

In order to cause the Escrow Agent to release the Escrow Property to us, on or prior to July 15, 2020 (the "Outside Date"), we must deliver an officer's certificate to the Escrow Agent certifying that the Acquisition will be consummated simultaneously or substantially concurrently with the release of funds from the escrow account (the "Escrow Release Condition").

If the Escrow Release Condition is satisfied prior to 11:59 p.m. (New York City time) on the Outside Date, the Escrow Agent will release the Escrow Property (including investment earnings) to or at the instruction of WPX.

If (i) the Escrow Release Condition has not been satisfied prior to 11:59 p.m. (New York City time) on the Outside Date or (ii) we deliver a termination notice to the Escrow Agent prior to 11:59 p.m. (New York City time) on the Outside Date indicating that (a) we will not pursue the consummation of the Acquisition or (b) we have determined in our sole discretion that the Escrow Release Condition cannot or is not reasonably likely to be satisfied by 11:59 p.m. (New York City time) on the Outside Date (any event described in clauses (i) or (ii) of this sentence, a "Special Mandatory Redemption Event"), the notes will be subject to a special mandatory redemption, at a price equal to 100% of the initial issue price of such series of notes, plus accrued and unpaid interest from the date of initial issuance of such series of notes to, but not including, the Special Mandatory Redemption Date (the "Special Mandatory Redemption Price").

Upon the occurrence of a Special Mandatory Redemption Event, we will promptly (but in no event later than three Business Days following such Special Mandatory Redemption Event) notify the holders of such event (with a copy of the notice to be simultaneously delivered to the trustee) (such date of notification to the holders, the "Special Mandatory Redemption Notice Date"), that the notes will be redeemed no later than five Business Days (and no sooner than two Business Days) after the date of the Special Mandatory Redemption Notice Date (such date, the "Special Mandatory Redemption Date"), in each case in accordance with the applicable provisions of the indenture. The notice provided on the Special Mandatory Redemption Notice Date shall notify each holder in accordance with the applicable provisions of the indenture that all of the outstanding notes shall be redeemed at the Special Mandatory Redemption Price on the Special Mandatory Redemption Date automatically and without any further action by the holders of any series of the notes.

On or before the Business Day immediately prior to the Special Mandatory Redemption Date, the Escrow Agent shall release the Escrow Property (including investment earnings) to the trustee, without the requirement of notice to or action by us, the trustee or any other person, and, on or prior to the Special Mandatory Redemption Date, we will provide to the trustee any additional amounts necessary

to fund the redemption of the notes at the Special Mandatory Redemption Price. On the Special Mandatory Redemption Date, the trustee shall cause the redemption of the notes and the payment to the holders of the Special Mandatory Redemption Price.

At any time prior to , 2023, we may, on any one or more occasions, redeem up to 35% of the aggregate principal amount of each series of notes (including any additional notes of such series) issued under the indenture, upon notice as provided in the indenture, in the case of the 2028 notes, at a redemption price equal to % of the principal amount of the 2028 notes redeemed, plus accrued and unpaid interest, if any, and, in the case of the 2030 notes, at a redemption price equal to % of the principal amount of the 2030 notes redeemed, plus accrued and unpaid interest, if any, in each case to but excluding the date of redemption (subject to the rights of holders of notes on the relevant record date to receive interest due on an interest payment date that is on or prior to the redemption date), with an aggregate amount of cash not greater than the net cash proceeds of one or more Equity Offerings, provided that:

For the avoidance of doubt, the aggregate redemption price paid by us in respect of any redemptions of the 2028 notes and the 2030 notes pursuant to the foregoing paragraph shall not exceed the aggregate net cash proceeds received in the applicable Equity Offering(s).

At any time prior to , 2023 in the case of the 2028 notes and , 2025 in the case of the 2030 notes, we may, on any one or more occasions, redeem the applicable series of notes, in whole or in part, upon notice as provided in the indenture, at a redemption price equal to 100% of the principal amount of the notes redeemed, plus the Applicable Premium, and accrued and unpaid interest, if any, to the date of redemption, subject to the rights of holders of notes on the relevant record date to receive interest due on an interest payment date that is on or prior to the redemption date.

On or after , 2023 in the case of the 2028 notes and , 2025 in the case of the 2030 notes, we may, on any one or more occasions, redeem the applicable series of notes, in whole or in part, upon notice as provided in the indenture, at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest, if any, on the notes redeemed, to the applicable date of redemption, if redeemed during the twelve-month period beginning on of the years indicated below, subject to the rights of holders of notes on the relevant record date to receive interest due on an interest payment date that is on or prior to the redemption date:

If less than all of a series of notes are to be redeemed at any time, the notes of such series shall be selected for redemption in accordance with standard procedures of DTC.

No notes of $2,000 or less can be redeemed in part. Notices of optional redemption will be sent at least 15 but not more than 60 days before the redemption date to each holder of the series of notes to be redeemed at its registered address. Notices of redemption may be conditioned on one or more conditions precedent specified in the notice.

If the applicable series of notes are to be redeemed in part only, the notice of redemption will state the portion of the principal amount of such series of notes that are to be redeemed. New notes of the applicable series in principal amount equal to the unredeemed portion of the original notes of the applicable series will be issued in the name of the holders of the notes upon cancellation of the original notes. Notes called for redemption become due on the date fixed for redemption, subject to the satisfaction of any conditions to the redemption. On and after the redemption date, interest will cease to accrue on the applicable series of notes or portions of them called for redemption.

If a Change of Control occurs and is accompanied by a Rating Decline with respect to a series of notes (together, a "Change of Control Triggering Event"), each registered holder of notes of such series will have the right to require us to offer to repurchase all or any part (equal to $1,000 or an integral multiple of $1,000 in excess thereof, provided that the unpurchased portion of any note must be in a minimum denomination of $2,000) of such holder's notes at a purchase price in cash equal to 101% of the principal amount of such notes plus accrued and unpaid interest, if any, to the date of purchase.

Within 30 days following any Change of Control Triggering Event, we will send a notice (the "Change of Control Offer") to each registered holder of such series of notes with a copy to the trustee stating:

The Paying Agent will promptly mail or otherwise deliver to each holder of notes so tendered the Change of Control Payment for such notes, and the trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each holder a new note equal in principal amount to any unpurchased portion of the notes surrendered, if any; provided that each such new note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

If the Change of Control Payment Date is on or after an interest record date and on or before the related interest payment date of notes of the applicable series, accrued and unpaid interest, if any, will be paid to the person in whose name such note is registered at the close of business on such record date, and no additional interest will be payable to holders who tender pursuant to the Change of Control Offer.

Except as described above with respect to a Change of Control Triggering Event, the indenture does not contain provisions that permit the holders to require that we repurchase or redeem the notes in the event of a takeover, recapitalization or similar transaction.

We will not be required to make a Change of Control Offer upon a Change of Control Triggering Event if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in the indenture applicable to a Change of Control Offer made by us and purchases all notes validly tendered and not withdrawn under such Change of Control Offer.

Our and our subsidiaries' current and/or future debt instruments may require that we repay or refinance indebtedness under such debt instruments in the event of a change of control, as defined in such debt instruments. Such change of control provisions may be triggered under such debt instruments prior to the occurrence of a Change of Control Triggering Event, thereby requiring that the indebtedness under such debt instruments be repaid or refinanced prior to our repurchasing any notes upon the occurrence of a Change of Control Triggering Event. Moreover, the exercise by the holders of their right to require us to repurchase the notes could cause a default under such debt instruments, even if the Change of Control Triggering Event itself does not, due to the financial effect of such repurchase on us. In such event, we may not be able to satisfy our obligations to repurchase the notes unless we are able to refinance or obtain waivers with respect to such debt instruments.

Finally, our ability to pay cash to the holders upon a repurchase may be limited by our then existing financial resources. There can be no assurance that sufficient funds will be available when necessary to make any required repurchases.

Even if sufficient funds were otherwise available, the terms of our current and/or future debt instruments may prohibit our prepayment of notes before their scheduled maturity. Consequently, if we are not able to prepay the indebtedness under such debt instruments or obtain requisite consents, we will be unable to fulfill our repurchase obligations if holders of the notes exercise their repurchase right following a Change of Control Triggering Event, resulting in an Event of Default under the indenture. An Event of Default under the indenture may result in a default under our current and/or future debt instruments.

We will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control offer provisions of the notes, we will comply with those securities laws and regulations and will not be deemed to have breached our obligations under the Change of Control offer provisions of the notes by virtue of any such conflict.

If holders of not less than 90% in aggregate principal amount of the outstanding notes of a series validly tender and do not withdraw such notes in a Change of Control Offer and we, or any third party making a Change of Control Offer as described above, purchase all of the notes of such series validly tendered and not withdrawn by such Holders, we or such third party will have the right, upon not less than 15 nor more than 60 days' prior notice to holders, given not more than 30 days following such purchase pursuant to the Change of Control Offer, to redeem all notes of such series that remain outstanding following such purchase at a price in cash equal to 101% of the principal amount thereof plus accrued and unpaid interest thereon, if any, to, but excluding, the redemption date.

The definition of "Change of Control" includes a phrase relating to the sale, lease, transfer, conveyance or other disposition of "all or substantially all" of our assets and those of our Subsidiaries taken as a whole.

Although there is a limited body of case law interpreting the phrase "substantially all," there is no precise established definition of the phrase under applicable law. Accordingly, in certain circumstances there may be a degree of uncertainty as to whether a particular transaction would involve "all or substantially all" of the properties or assets of a Person.

We are not required to make mandatory redemption or sinking fund payments with respect to the notes other than as set forth above under "—Escrow of Proceeds—Special Mandatory Redemption."

Except as set forth in this "Description of Notes," neither we nor any of our Subsidiaries will be restricted by the indenture from incurring additional indebtedness or other obligations, from making distributions or paying dividends on our or our Subsidiaries' equity interests or from purchasing our or our Subsidiaries' equity interests. The indenture does not require the maintenance of any financial ratios or specified levels of net worth or liquidity. In addition, the indenture does not contain any provisions that would require us to repurchase or redeem any of the notes in situations that may adversely affect the creditworthiness of the notes.

We will not, and will not permit any Subsidiary of ours to, issue, assume or guarantee any Indebtedness secured by a Lien, other than Permitted Liens, upon any of our or any of our Subsidiaries' property, now owned or hereafter acquired, unless the notes are equally and ratably secured with such Indebtedness until such time as such Indebtedness is no longer secured by a Lien.

Notwithstanding the preceding paragraph, we may, and may permit any Subsidiary of ours to, issue, assume or guarantee any Indebtedness secured by a Lien, other than a Permitted Lien, without securing the notes; provided that the aggregate principal amount of all Indebtedness of ours and any Subsidiary of ours then outstanding secured by any such Liens (other than Permitted Liens) does not exceed 15% of Consolidated Net Tangible Assets.

The indenture provides that we may not directly or indirectly consolidate with or merge with or into, or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of our assets and properties and the assets and properties of our Subsidiaries (taken as a whole) in one or more related transactions to another Person (as defined in the indenture), unless:

Upon any consolidation by us with or our merger into any other Person or Persons where we are not the survivor or any sale, assignment, transfer, lease, conveyance or other disposition of all or substantially all of our properties and assets and the properties and assets of our Subsidiaries (taken as a whole) to any Person or Persons in accordance herewith, the successor Person formed by such consolidation or into which we are merged or to which such sale, assignment, transfer, lease, conveyance or other disposition is made shall succeed to, and be substituted for, and may exercise every right and power of, us under the indenture with the same effect as if such successor Person had been named as WPX therein; and thereafter, except in the case of a lease, the predecessor Person shall be released from all obligations and covenants under the indenture and the debt securities.

An assumption of our obligations on the notes and under the indenture by any successor Person might be deemed for U.S. federal income tax purposes to cause an exchange of the notes for new notes by the beneficial owners thereof, resulting in recognition of gain or possible loss for such purposes and possibly other adverse tax consequences to the beneficial owners. You should consult your tax advisors regarding the tax consequences of such an assumption.

We will be required to file with the trustee, within 30 days after we have filed the same with the SEC, copies of the annual reports and of the information, documents, and other reports that we are

required to file with the SEC pursuant to Section 13 or Section 15(d) of the Exchange Act or pursuant to Section 314 of the Trust Indenture Act. Annual reports, information, documents and reports that are filed by us with the SEC via the EDGAR system or any successor electronic delivery procedure will be deemed to be filed with the trustee at the time such documents are filed via the EDGAR system or such successor procedure. Delivery of such reports, information and documents to the trustee is for informational purposes only, and the trustee's receipt of such will not constitute constructive notice of any information contained therein or determinable from information contained therein, including our compliance with any of our covenants in the indenture.

Each of the following will constitute an event of default under the indenture with respect to a series of notes:

In case an event of default specified in clause (1) or (2) above shall occur and be continuing with respect to a series of notes, holders of at least 25%, and in case an event of default specified in clause (3) above shall occur and be continuing with respect to such series of notes, holders of at least a majority, in aggregate principal amount of such series then outstanding may declare the principal amount of all the notes of such series then outstanding under the indenture to be due and payable immediately. If an event of default described in clause (4) above shall occur and be continuing then the principal amount of all the notes of such series then outstanding under the indenture shall be and become due and payable immediately, without notice or other action by any holder or the trustee, to the full extent permitted by law.

Holders of the notes may not enforce the indenture or the notes except as provided in the indenture. Subject to certain limitations, holders of a majority in principal amount of the applicable series of the then outstanding notes may direct the trustee in its exercise of any trust or power with respect to such series of notes. The indenture provides that the trustee may withhold notice to the holders of a series of notes of any default with respect to such series of notes (except in payment of principal of or interest or premium on the notes) if the trustee considers it in the interest of holders of such series of notes to do so.

Holders of not less than a majority in principal amount of the applicable series of notes then outstanding by notice to the trustee may on behalf of the holders of all of the notes of such series, waive any past or existing default or event of default under the indenture and its consequences, except a continuing default (a) in the payment of principal of, or interest or premium, if any, on such series of notes or (b) in respect of a covenant or other provision of the indenture, which under the indenture cannot be modified or amended without the consent of the holder of each outstanding note of such series.

We are required to deliver to the trustee annually a statement regarding compliance with the indenture.

WPX will make payments in respect of the notes represented by the Global Notes (including principal, premium, if any, and interest) by wire transfer of immediately available funds to the accounts specified by DTC or its nominee. WPX will make all payments of principal, premium, if any, and interest with respect to Certificated Notes (i) to holders having an aggregate principal amount of $2,000,000 or less, by check mailed to such holder's registered address or (ii) to holders having an aggregate principal amount of more than $2,000,000, by check mailed to such holder's registered address or, upon application by a holder to the registrar not later than the relevant record date or in the case of payments of principal or premium, if any, not later than 15 days prior to the principal payment date, by wire transfer in immediately available funds to that holder's account within the United States (subject to surrender of the Certificated Note in the case of payments of principal or premium), which application shall remain in effect until the holder notifies the registrar to the contrary in writing. The notes represented by the Global Notes are expected to be eligible to trade in DTC's Same-Day Funds Settlement System, and any permitted secondary market trading activity in such notes will, therefore, be required by DTC to be settled in immediately available funds. WPX expect that secondary trading in any Certificated Notes will also be settled in immediately available funds.

Because of time zone differences, the securities account of a Euroclear or Clearstream participant purchasing an interest in a Global Note from a Participant will be credited, and any such crediting will be reported to the relevant Euroclear or Clearstream participant, during the securities settlement processing day (which must be a business day for Euroclear and Clearstream) immediately following the settlement date of DTC. DTC has advised WPX that cash received in Euroclear or Clearstream as a result of sales of interests in a Global Note by or through a Euroclear or Clearstream participant to a Participant will be received with value on the settlement date of DTC but will be available in the relevant Euroclear or Clearstream cash account only as of the business day for Euroclear or Clearstream following DTC's settlement date.

Set forth below are certain defined terms used in the indenture. Reference is made to the indenture for a full disclosure of all such terms, as well as any other capitalized terms used herein for which no definition is provided.

For purposes of this definition, "control," as used with respect to any Person, means the possession, directly or indirectly, of the power to direct or cause the direction of the management or policies of such Person, whether through the ownership of voting securities, by agreement or otherwise. For purposes of this definition, the terms "controlling," "controlled by" and "under common control with" have correlative meanings.

"Applicable Premium" means, with respect to any note at any redemption date, the greater of: (i) 1.0% of the principal amount of the note; or (ii) the excess of (A) the present value at such redemption date of (1) the redemption price of the note at , 2023 in the case of the 2028 notes and , 2025, in the case of the 2030 notes (in each case, such redemption price being set forth in the applicable table appearing above under the caption "—Optional Redemption") plus (2) all required interest payments due on the note through , 2023 in the case of the 2028 notes and , 2025, in the case of the 2030 notes (in each case excluding accrued but unpaid interest to the redemption date), computed using a discount rate equal to the Treasury Rate as of such redemption date plus basis points in the case of the 2028 notes and basis points in the case of the 2030 notes, in each case, discounted to the redemption date on a semi-annual basis (assuming a 360 day year consisting of twelve 30 day months), over (B) the principal amount of the note.

"Rating Decline" means, with respect to either series of notes, a decrease in the ratings of such series of notes by one or more gradations (including gradations within categories as well as between rating categories) as a result of a Change of Control by each of the Rating Agencies on any date from the date of the public notice of an arrangement that could result in a Change of Control until the end of the 30-day period following public notice of the occurrence of the Change of Control (which 30-day period will be extended so long as the rating of the notes of such series is under publicly announced consideration for possible downgrade by either of the Rating Agencies and the other Rating Agency has either downgraded, or publicly announced that it is considering downgrading, the notes of such series). Notwithstanding the foregoing, if the notes of such series have an Investment Grade Rating by each of the Rating Agencies, then "Ratings Decline" means a decrease in the ratings of the notes of such series by one or more gradations (including gradations within categories as well as between rating categories) as a result of a Change of Control by each of the Rating Agencies such that the rating of the notes of such series by each of the Rating Agencies falls below an Investment Grade Rating on any date from the date of the public notice of an arrangement that could result in a Change of Control until the end of the 30-day period following public notice of the occurrence of the Change of Control (which 30-day period will be extended so long as the rating of the notes of such series is under publicly announced consideration for possible downgrade by either of the Rating Agencies and the other Rating Agency has either downgraded, or publicly announced that it is considering downgrading, the notes of such series).

"S&P" means S&P Global Ratings, a division of S&P Global, Inc., or, if S&P Global Ratings shall cease rating debt securities having a maturity at original issue of at least one year and such ratings business shall have been transferred to a successor Person, such successor Person; provided, however, that if there is no successor Person, then "S&P" shall mean any other national recognized rating agency, other than Moody's, that rates debt securities having a maturity at original issuance of at least one year and that shall have been designated by WPX.

"Treasury Rate" means, in respect of any redemption date, the yield to maturity, as of the time of computation, of the most recently issued United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15 that has become publicly available at least two business days prior to such time (or, if such Statistical Release is no longer published, any publicly available source of similar market data)) most nearly equal to the period from the redemption date to , 2023, in the case of the 2028 notes and , 2025 in the case of the 2030 notes, provided, however, that if the period from the redemption date to , 2023, in the case of the 2028 notes and , 2025 in the case of the 2030

notes, is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year will be used. The Company will (a) calculate the Treasury Rate no later than the second (and no earlier than the fourth) Business Day preceding the applicable redemption date and (b) prior to such redemption date, file with the trustee a statement setting forth the Applicable Premium and the Treasury Rate and showing the calculation of each in reasonable detail.

"Voting Stock" of any Person as of any date means the Capital Stock of such Person that is at the time entitled (without regard to the occurrence of any contingency) to vote in the election of the Board of Directors of such Person.

The notes offered hereby will initially be issued in registered, global form without interest coupons (the "Global Notes") in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. Notes will be issued at the closing of this offering only against payment in immediately available funds. The Global Notes will be deposited upon issuance with the trustee as custodian for The Depository Trust Company ("DTC"), and registered in the name of DTC or its nominee, for credit to an account of a direct or indirect participant in DTC as described below.

Except as set forth below, the Global Notes may be transferred, in whole but not in part, only to DTC, to another nominee of DTC or to a successor of DTC or its nominee. Only in the limited circumstances described below may beneficial interests in the Global Notes be exchanged for definitive notes in registered certificated form ("Certificated Notes") in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. See "—Exchange of Global Notes for Certificated Notes." Notes will be issued at the closing of this offering only against payment in immediately available funds.

Transfers of beneficial interests in the Global Notes will be subject to the applicable rules and procedures of DTC and its direct or indirect participants (including, if applicable, those of the Euroclear System ("Euroclear'") and Clearstream Banking, S.A. ("Clearstream")), which may change from time to time.

The following description of the operations and procedures of DTC, Euroclear and Clearstream are provided solely as a matter of convenience. These operations and procedures are solely within the control of the respective settlement systems and are subject to changes by them. WPX takes no responsibility for these operations and procedures and urge investors to contact the system or their participants directly to discuss these matters.

DTC has advised WPX that DTC is a limited-purpose trust company created to hold securities for its participating organizations (collectively, the "Participants") and to facilitate the clearance and settlement of transactions in those securities between the Participants through electronic book-entry changes in accounts of its Participants. The Participants include securities brokers and dealers (including the initial purchasers), banks, trust companies, clearing corporations and certain other organizations. Access to DTC's system is also available to other entities such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Participant, either directly or indirectly (collectively, the "Indirect Participants"). Persons who are not Participants may beneficially own securities held by or on behalf of DTC only through the Participants or the Indirect Participants. The ownership interests in, and transfers of ownership interests in, each security held by or on behalf of DTC are recorded on the records of the Participants and Indirect Participants.

DTC has advised WPX that its current practice, upon receipt of any payment in respect of securities such as the notes (including principal and interest), is to credit the accounts of the relevant Participants with the payment on the payment date unless DTC has reason to believe that it will not

receive payment on such payment date. Each relevant Participant is credited with an amount proportionate to its beneficial ownership of an interest in the principal amount of the relevant security as shown on the records of DTC. Payments by the Participants and the Indirect Participants to the beneficial owners of notes will be governed by standing instructions and customary practices and will be the responsibility of the Participants or the Indirect Participants and will not be the responsibility of DTC, the trustee or WPX. Neither WPX nor the trustee will be liable for any delay by DTC or any of the Participants or the Indirect Participants in identifying the beneficial owners of the notes, and WPX and the trustee may conclusively rely on and will be protected in relying on instructions from DTC or its nominee for all purposes.

Transfers between the Participants will be effected in accordance with DTC's procedures, and will be settled in same-day funds, and transfers between participants in Euroclear and Clearstream will be effected in accordance with their respective rules and operating procedures.

Subject to compliance with the transfer restrictions applicable to the notes described herein, cross-market transfers between the Participants, on the one hand, and Euroclear or Clearstream participants, on the other hand, will be effected through DTC in accordance with DTC's rules on behalf of Euroclear or Clearstream, as the case may be, by their respective depositaries; however, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counterparty in such system in accordance with the rules and procedures and within the established deadlines (Brussels time) of such system. Euroclear or Clearstream, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its respective depositary to take action to effect final settlement on its behalf by delivering or receiving interests in the relevant Global Note in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear participants and Clearstream participants may not deliver instructions directly to the depositories for Euroclear or Clearstream.

DTC has advised WPX that it will take any action permitted to be taken by a holder of notes only at the direction of one or more Participants to whose account DTC has credited the interests in the Global Notes and only in respect of such portion of the aggregate principal amount of the notes as to which such Participant or Participants has or have given such direction. However, if there is an Event of Default under the notes, DTC reserves the right to exchange the Global Notes for Certificated Notes, and to distribute such notes to its Participants.

Although DTC, Euroclear and Clearstream have agreed to the foregoing procedures to facilitate transfers of interests in the Global Notes among participants in DTC, Euroclear and Clearstream, they are under no obligation to perform or to continue to perform such procedures, and may discontinue such procedures at any time. None of WPX, the trustee or any of their respective agents will have any responsibility for the performance by DTC, Euroclear or Clearstream or their respective participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

In addition, beneficial interests in a Global Note may be exchanged for Certificated Notes of the same series upon prior written notice given to the trustee by or on behalf of DTC in accordance with the indenture. In all cases, Certificated Notes delivered in exchange for any Global Note or beneficial interests in Global Notes will be registered in the names, and issued in any approved denominations, requested by or on behalf of the depositary (in accordance with its customary procedures).

This section summarizes the material U.S. federal income tax considerations relating to the purchase, ownership, and disposition of the notes. This summary does not provide a complete analysis of all potential tax considerations. The information provided below is based on the Internal Revenue Code of 1986, as amended (referred to herein as the "Code"), Treasury regulations issued under the Code, judicial authority and administrative rulings and practice, all as of the date of this prospectus supplement and all of which are subject to change, possibly on a retroactive basis. As a result, the tax considerations of purchasing, owning or disposing of the notes could differ from those described below. This summary deals only with beneficial owners who purchase (or are deemed to purchase) the notes for cash on original issuance at the first price at which a substantial portion of the notes of the applicable series is sold for money pursuant to this offering (other than to bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers), and who hold the notes as "capital assets" within the meaning of Section 1221 of the Code. This summary does not address all U.S. federal income tax considerations that may be relevant to persons in special tax situations, such as financial institutions, insurance companies, S corporations, regulated investment companies, real estate investment trusts, tax-exempt investors, dealers in securities and currencies, traders in securities that elect to use a mark-to-market method of accounting for their securities, controlled foreign corporations, corporations that accumulate earnings to avoid U.S. federal income tax, U.S. expatriates, persons holding notes as a position in a "straddle," "hedge," "conversion transaction," or other integrated transaction for U.S. federal income tax purposes, persons subject to special tax accounting rules under Section 451(b) of the Code, investors in pass-through entities, and U.S. holders (as defined below) whose functional currency is not the U.S. dollar. Further, this discussion does not address the consequences under U.S. alternative minimum tax rules, U.S. federal estate or gift tax laws, the tax laws of any U.S. state or locality, any non-U.S. tax laws, or any tax laws other than income tax laws. We will not seek a ruling from the Internal Revenue Service (the "IRS") with respect to any of the matters discussed herein and there can be no assurance that the IRS will not challenge one or more of the tax consequences described herein.

As used herein, a "U.S. holder" is a beneficial owner of notes that is, for U.S. federal income tax purposes, a U.S. Person. As used herein, the term "non-U.S. holder" means a beneficial owner, other than a partnership (or entity treated as a partnership for U.S. federal income tax purposes), of notes that is not a U.S. holder.

If a partnership, including for this purpose any entity treated as a partnership for U.S. federal income tax purposes, is a beneficial owner of notes, the treatment of a partner in the partnership generally will depend upon the status of the partner and upon the activities of the partnership. A holder of notes that is a partnership and partners in such a partnership should consult their

independent tax advisors about the U.S. federal income tax consequences of holding and disposing of notes.

Investors should consult their tax advisors concerning the tax consequences of the purchase, ownership and disposition of the notes, including the tax consequences under the laws of any foreign, state, local or other taxing jurisdictions and the possible effects on investors of changes in U.S. federal or other tax laws.

We will be required to make payments on a note that would change the timing and amount of payments on the note in the circumstances described under "Description of Notes—Escrow of Proceeds; Special Mandatory Redemption" and "Description of Notes—Change of Control." We intend to take the position that the possibility of such payments does not result in the notes being treated as contingent payment debt instruments under the applicable Treasury regulations. Our position is not binding on the IRS. If the IRS successfully asserts a contrary position, a U.S. holder may be required to accrue interest income based upon a "comparable yield" (as defined in the Treasury regulations) determined at the time of issuance of the notes (which is not expected to differ significantly from the actual yield on the notes of the applicable series), with adjustments to such accruals if and when any contingent payments are made that differ from the payments based on the comparable yield. In addition, any income on the sale, exchange, redemption, retirement or other taxable disposition of the notes would be treated as ordinary interest income rather than as capital gain. You should consult your tax advisor regarding the tax consequences if the notes were treated as contingent payment debt instruments. The remainder of this discussion assumes that the notes are not treated as contingent payment debt instruments.

It is anticipated, and this discussion assumes, that the notes will be issued without original issue discount for U.S. federal income tax purposes. In such case, interest on a note will be includable by a U.S. holder as interest income at the time it accrues or is received in accordance with such holder's method of accounting for U.S. federal income tax purposes and will be ordinary income.

Sale, Exchange, Redemption, Retirement or Other Taxable Disposition of the Notes

Upon a sale, exchange, redemption, retirement or other taxable disposition of a note, a U.S. holder will generally recognize gain or loss equal to the difference between (i) the amount realized on the disposition (other than amounts attributable to accrued but unpaid interest, which will be taxed as interest income as discussed above to the extent not previously included in income) and (ii) the U.S. holder's tax basis in the note. A U.S. holder's tax basis in a note generally will equal the cost of the note. A U.S. holder's gain or loss will generally constitute capital gain or loss and will be long-term capital gain or loss if the U.S. holder has held such note for longer than one year. The deductibility of capital losses is subject to certain limitations. Net long-term capital gain recognized by a non-corporate U.S. holder is generally taxed at preferential rates.

U.S. holders who are individuals, estates or certain trusts are required to pay an additional 3.8% Medicare tax on the lesser of (1) the U.S. holder's "net investment income" (or undistributed "net investment income" in the case of estates and trusts) for the relevant taxable year and (2) the excess of the U.S. holder's modified gross income for the taxable year over a certain threshold (which in the case of individuals will be between $125,000 and $250,000 depending on the individual's circumstances). Net

investment income will generally include interest income and net gains from the disposition of the notes, unless such interest income or net gains are derived in the ordinary course of the conduct of a trade or business (other than a trade or business that consists of certain passive or trading activities). A U.S. holder that is an individual, estate or trust should consult its tax advisor regarding the applicability of the Medicare tax to its income and gains in respect of its investment in the notes.

In general, a U.S. holder will be subject to backup withholding on payments with respect to the notes, unless the U.S. holder (i) is an entity that is exempt from backup withholding (generally including tax-exempt organizations and certain qualified nominees) and, when required, provides appropriate documentation to that effect or (ii) provides the applicable withholding agent with the U.S. holder's social security number or other taxpayer identification number ("TIN"), certifies that the TIN provided is correct and that the U.S. holder has not been notified by the IRS that it is subject to backup withholding due to underreporting of interest or dividends, and otherwise complies with applicable requirements of the backup withholding rules. In addition, such payments to U.S. holders that are not exempt entities will generally be subject to information reporting requirements. A U.S. holder who does not provide the applicable withholding agent with the correct TIN may be subject to penalties imposed by the IRS. The amount of any backup withholding from a payment to a U.S. holder will be allowed as a credit against such holder's U.S. federal income tax liability and may entitle such holder to a refund, provided that the required information is timely furnished to the IRS.

Subject to the discussions of backup withholding and the Foreign Account Tax Compliance Act ("FATCA") below, interest income of a non-U.S. holder will qualify for the "portfolio interest exemption" and therefore not be subject to U.S. federal income tax or withholding, provided that:

If any of these conditions are not met, interest on the notes paid to a non-U.S. holder will generally be subject to U.S. federal withholding tax at a 30% rate unless (a) an applicable income tax

treaty reduces or eliminates such tax, and the non-U.S. holder claims the benefit of that treaty by providing an IRS Form W-8BEN or IRS Form W-8BEN-E (or a suitable substitute or successor form or such other form as the IRS may prescribe) that has been properly completed and duly executed, or (b) the interest is ECI and the non-U.S. holder complies with applicable certification requirements by providing an IRS Form W-8ECI (or a suitable substitute or successor form or such other form as the IRS may prescribe) that has been properly completed and duly executed.

If the interest on the notes is ECI, the non-U.S. holder will be required to pay U.S. federal income tax on that interest on a net income basis generally in the same manner as a U.S. holder (and the 30% withholding tax described above will not apply, provided the appropriate statement is provided to the applicable withholding agent). If, however, a non-U.S. holder is eligible for the benefits of any income tax treaty between the United States and its country of residence, any interest income that is ECI will be subject to U.S. federal income tax in the manner specified by the treaty and will generally be subject to U.S. federal income tax only if such income is attributable to a permanent establishment or a fixed base maintained by the non-U.S. holder in the United States and the non-U.S. holder claims the benefit of the treaty by providing an IRS Form W-8BEN or IRS Form W-8BEN-E (or a suitable substitute or successor form or such other form as the IRS may prescribe) that has been properly completed and duly executed. In addition, interest received by a corporate non-U.S. holder that is ECI may also, under certain circumstances, be subject to an additional "branch profits tax" at a 30% rate, or, if applicable, a lower treaty rate.

Sale, Exchange, Redemption, Retirement or Other Taxable Disposition of the Notes

Subject to the discussions of backup withholding and FATCA below, a non-U.S. holder will generally not be subject to U.S. federal income tax on any gain realized on a sale, exchange, redemption, retirement or other taxable disposition of the notes unless:

If a non-U.S. holder falls under the first of these exceptions, the holder will be taxed on the net gain derived from the disposition under the graduated U.S. federal income tax rates that are applicable to U.S. Persons and, if the non-U.S. holder is a foreign corporation, it may also be subject to the branch profits tax described above.

If an individual non-U.S. holder falls under the second of these exceptions, the holder generally will be subject to U.S. federal income tax at a rate of 30% (or, if applicable, a lower treaty rate) on the gain derived from the disposition, which may be offset by capital losses allocable to sources within the United States for the taxable year of the disposition.

Generally, the amount of interest paid to a non-U.S. holder and the amount of tax, if any, withheld with respect to those payments must be reported annually to the IRS and to the non-U.S. holder. Copies of the information returns reporting such interest, and any withholding may also be made available to the tax authorities in the country in which the non-U.S. holder resides under the provisions of an applicable income tax treaty. Backup withholding will generally not apply to payments of interest on the notes to a non-U.S. holder if the holder certifies its status as a non-U.S. person under penalties of perjury or otherwise establishes an exemption (provided that the applicable

withholding agent does not have actual knowledge or reason to know that the non-U.S. holder is a U.S. Person or that the conditions of any other exemptions are not in fact satisfied).

The payment of the proceeds of the disposition of notes to or through the United States office of a United States or foreign broker will be subject to information reporting and, depending on the circumstances, backup withholding unless the non-U.S. holder provides the certification described above or otherwise establishes an exemption (and the applicable withholding agent does not have actual knowledge or reason to know that the non-U.S. holder is a U.S. Person or that the conditions of any other exemptions are not in fact satisfied). The payment of the proceeds of a disposition effected outside the United States by a non-U.S. holder to or through a foreign office of a broker generally will not be subject to backup withholding or information reporting. However, if that broker is, for U.S. federal income tax purposes, a U.S. person, a controlled foreign corporation, a foreign person 50% or more of whose gross income from all sources for certain periods is effectively connected with a trade or business in the United States, or a foreign partnership that is engaged in the conduct of a trade or business in the United States or that has one or more partners that are U.S. persons who in the aggregate hold more than 50% of the income or capital interests in the partnership, information reporting requirements will apply unless that broker has documentary evidence in its files of such holder's status as a non-U.S. holder and has no actual knowledge or reason to know to the contrary or unless such holder otherwise establishes an exemption.

Any amounts withheld from a payment to a non-U.S. holder under the backup withholding rules will be allowed as a credit against such holder's U.S. federal income tax liability and may entitle it to a refund, provided it timely furnishes the required information to the IRS.

Pursuant to legislation commonly referred to as "FATCA" and regulations promulgated thereunder, payments to foreign entities of interest on debt obligations of a U.S. issuer will be subject to a withholding tax at a rate of 30%, unless (1) a foreign financial institution that is a payee undertakes certain diligence and reporting obligations, (2) a non-financial foreign entity that is a payee either certifies it does not have any "substantial United States owners" (as defined in the Code) or furnishes identifying information regarding each substantial United States owner, or (3) a foreign financial institution or non-financial foreign entity that is a payee otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in (1) above, it must enter into an agreement with the U.S. Department of the Treasury requiring, among other things, that it undertake to identify accounts held by certain "specified United States persons" or "United States owned foreign entities" (each as defined in the Code), annually report certain information about such accounts, and withhold 30% on certain payments to non-compliant foreign financial institutions and certain other account holders. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.

While withholding under FATCA would have applied also to payments of gross proceeds from the sale or other disposition of notes on or after January 1, 2019, proposed U.S. Treasury regulations published on December 18, 2018 eliminate FATCA withholding on payments of gross proceeds entirely. Taxpayers generally may rely on these proposed U.S. Treasury regulations until final U.S. Treasury regulations are issued.

Investors should consult their tax advisors regarding the possible effect of FATCA and the regulations thereunder with respect to their investment in the notes.

The U.S. federal tax discussion set forth above as to both U.S. holders and non-U.S. holders is included for general information only and may not be applicable depending upon a holder's particular situation. Holders should consult their tax advisors with respect to the tax consequences to them of the purchase, ownership and disposition of the notes, including the tax consequences under state, local, foreign and other tax laws and the possible effects of changes in U.S. federal or other tax laws.

The underwriting agreement provides that the obligation of the underwriters to purchase the notes included in this offering is subject to approval of legal matters by counsel and certain other conditions. Under the terms and conditions of the underwriting agreement, if the underwriters purchase any of the notes, then they are obligated to purchase all of the notes.

The underwriters propose to offer the notes initially at the public offering price on the cover page of this prospectus supplement. After the initial offering of the notes to the public, the public offering prices and other selling terms to dealers may be changed. The underwriters may offer and sell notes through certain of their affiliates. The offering of the notes by the underwriters is subject to receipt and acceptance of the notes and subject to the underwriters' right to reject any order in whole or in part.

We have agreed not to offer or sell any of our debt securities (other than the notes) for a period of 45 days after the date of this prospectus supplement without the prior written consent of Barclays Capital Inc.

We estimate that the total expenses of this offering to be paid by us, excluding underwriting discounts, will be approximately $2.5 million.

In connection with this offering and in compliance with applicable law, the underwriters may engage in over-allotment, and stabilizing and syndicate covering transactions in accordance with Regulation M under the Exchange Act.

These stabilizing transactions and syndicate covering transactions may have the effect of preventing or retarding a decline in the market price of the notes. They may also cause the prices of the notes to be higher than they would otherwise be in the absence of these transactions. These transactions may be effected in the over-the-counter market or otherwise. The underwriters are not required to engage in any of these activities and such activities, if commenced, may be discontinued at any time.

Neither we nor any of the underwriters makes any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the notes. In addition, neither we nor any of the underwriters makes any representation that the underwriters will engage in such transactions or that such transactions, once commenced, will not be discontinued without notice.

The notes are offered for sale only in those jurisdictions where it is legal to offer them. The offering of the notes by the underwriters is subject to receipt and acceptance and subject to the underwriters' right to reject any order in whole or in part.

The notes are new issues of securities for which there is currently no established trading market. The underwriters have advised us that they intend to make a market in the notes, as permitted by applicable law. The underwriters are not obligated, however, to make a market in the notes, and may discontinue any market-making activities at any time without notice, in their sole discretion. If the underwriters cease to act as a market-maker for the notes for any reason, there can be no assurance that another firm or person will make a market in the notes. Accordingly, we cannot assure you as to the development or liquidity of any market for these notes. The notes will not be listed on any securities exchange or included in any automated quotation system.

We have agreed to indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act, the Exchange Act or other Federal or state statutory law or to contribute to payments that the underwriters may be required to make in respect of any such liabilities.

It is expected that delivery of the notes offered pursuant to this prospectus will be made to investors on or about , 2020, which will be the business day following the date of this prospectus (such settlement being referred to as "T+ "). Under Rule 15c6-1 of the Exchange Act as currently in effect, trades in the secondary market are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes prior to two business days before the notes are delivered will be required, by virtue of the fact that the notes initially settle in T+ , to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement. Purchasers of the notes who wish to trade such notes prior to their date of delivery hereunder should consult their advisors.

Absent a Special Mandatory Redemption Event, affiliates of certain of the underwriters may receive at least 5% of the net proceeds of this offering in connection with the repayment of all remaining amounts outstanding under the Felix Debt Facilities. See "Use of Proceeds." Accordingly, this offering is being made in compliance with the requirements of FINRA Rule 5121. Because such underwriters are not primarily responsible for managing this offering, pursuant to Rule 5121, the appointment of a qualified independent underwriter is not necessary. Pursuant to FINRA Rule 5121, such underwriters will not confirm sales of the notes to any account over which they exercise discretionary authority without the prior written approval of the customer.

Certain of the underwriters and their affiliates have performed investment banking, commercial banking and advisory services for us and our affiliates from time to time for which they have received customary fees and expenses. The underwriters and their affiliates may, from time to time in the future, engage in transactions with and perform services for us and our affiliates in the ordinary course of business. In particular, affiliates of Barclays Capital Inc., Citigroup Global Markets Inc. and certain of the other underwriters or their affiliates are agents and/or lenders under the Credit Facility, and certain of the underwriters and their affiliates are agents and/or lenders under the Felix Revolving Credit Facility. Certain of the underwriters or their affiliates may also hold our equity or debt securities from time to time. A portion of the proceeds of this offering may be used to repay the Felix Revolving Credit Facility and the Felix Parent Notes Facility. Accordingly, certain underwriters and/or their affiliates may receive a portion of the proceeds of this offering. In addition, certain of the underwriters and/or their affiliates have made commitments to us with respect to an unsecured bridge facility (the "Bridge Facility") to finance a portion of the Unadjusted Cash Purchase Price for the Acquisition in an aggregate amount up to $450 million, with respect to which they will be paid customary fees. If we are unable to consummate this offering, we may draw on the Bridge Facility as well as our existing Credit Facility to finance the Unadjusted Cash Purchase Price for the Acquisition. The aggregate amount of commitments in respect of the Bridge Facility will be reduced by the gross proceeds of this offering. See "Use of Proceeds."

If the underwriters and/or their respective affiliates have a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, and certain of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and their respective affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby.

The underwriters and their respective affiliates may also communicate independent investment recommendations, market color or trading ideas and/or publish or express independent research views in respect of our assets, securities or instruments and the underwriters may at any time hold, or recommend to clients that they should acquire long and/or short positions of our assets, securities and instruments.

The notes may be sold only to purchasers purchasing, or deemed to be purchasing, as principal that are accredited investors, as defined in National Instrument 45-106 Prospectus Exemptions or subsection 73.3(1) of the Securities Act (Ontario), and are permitted clients, as defined in National Instrument 31-103 Registration Requirements, Exemptions and Ongoing Registrant Obligations. Any resale

of the notes must be made in accordance with an exemption from, or in a transaction not subject to, the prospectus requirements of applicable securities laws.

Securities legislation in certain provinces or territories of Canada may provide a purchaser with remedies for rescission or damages if this prospectus supplement and the accompanying prospectus (including any amendment thereto) contain a misrepresentation, provided that the remedies for rescission or damages are exercised by the purchaser within the time limit prescribed by the securities legislation of the purchaser's province or territory. The purchaser should refer to any applicable provisions of the securities legislation of the purchaser's province or territory for particulars of these rights or consult with a legal advisor.

Pursuant to section 3A.3 of National Instrument 33-105 Underwriting Conflicts (NI 33-105), the underwriters are not required to comply with the disclosure requirements of NI 33-105 regarding underwriter conflicts of interest in connection with this offering.

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area ("EEA"). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, "MiFID II"); or (ii) a customer within the meaning of Directive 2002/92/EC (as amended or superseded, the "Insurance Mediation Directive"), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Directive 2003/71/EC (as amended, the "Prospectus Directive") . Consequently no key information document required by Regulation (EU) No 1286/2014 (as amended or superseded, the "PRIIPs Regulation") for offering or selling the notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPS Regulation. This prospectus supplement and the accompanying prospectus have been prepared on the basis that any offer of notes in any member state of the EEA will be made pursuant to an exemption under the Prospectus Directive from the requirement to publish a prospectus for offers of notes. This prospectus supplement and the accompanying prospectus are not a prospectus for the purposes of the Prospectus Directive.

RATIO OF EARNINGS TO FIXED CHARGES

			Year Ended December 31,

	Nine Months Ended September 30, 2017		Year Ended December 31,
	Nine Months Ended September 30, 2017		2016		2015		2014		2013		2012
Ratio of earnings to fixed charges		1.13		(a)		1.10		4.16		(c)		1.12
Ratio of earnings to combined fixed charges and preferred dividends		1.01		(b)		1.02		4.16		(c)		1.12

(a): Earnings were inadequate to cover fixed charges by $936 million.
(b): Earnings were inadequate to cover combined fixed charges and preferred dividends by $965 million.

Fixed charges consist of interest accrued, including proportionate share from 50% owned investees and unconsolidated majority-owned investees and rental expense in an amount deemed to be representative of the interest factor.

The ratio of earnings to combined fixed charges and preferred dividends has been computed by dividing (i) income (loss) from continuing operations before income taxes and equity earnings, (ii) fixed charges and (iii) distributed income of equity-method investees, excluding proportionate share from 50% owned investees and unconsolidated majority-owned investees less capitalized interest by fixed charges plus our preferred dividend requirement.

Many of the factors that will determine these results are beyond our ability to control or predict. Specific factors that could cause actual results to differ from results contemplated by the forward-looking statements include, among others, the following:

In addition to causing our actual results to differ, the factors listed above may cause our intentions to change from those statements of intention set forth in or incorporated by reference in this prospectus. Such changes in our intentions may also cause our results to differ. We may change our intentions, at any time and without notice, based upon changes in such factors, our assumptions or otherwise.

Unless otherwise stated in the prospectus supplement accompanying this prospectus, we will use the net proceeds from the sale of any securities that may be offered hereby for our general corporate purposes, which may include repayment of indebtedness, acquisitions, working capital, capital expenditures and repurchases of our common stock. Pending any specific application, we may initially invest funds in short-term marketable securities.

The following is a description of the material terms of our capital stock as provided in our amended and restated certificate of incorporation and amended and restated bylaws. We also refer you to our amended and restated certificate of incorporation (including our amendment to our amended and restated certificate of incorporation) and our amended and restated bylaws, copies of which are incorporated by reference as exhibits to the registration statement of which this prospectus forms a part.

Our authorized capital stock consists of (i) 2,000,000,000 shares of common stock, par value $0.01 per share and (ii) 100,000,000 shares of preferred stock, par value $0.01 per share. As of September 30, 2017, we had 398.1 million shares of common stock outstanding. As of September 30, 2017, there were 4.8 million shares of our 6.25% Series A Mandatory Convertible Preferred Stock ("Preferred Stock") issued and outstanding.

Authorized but unissued shares of our capital stock may be used for a variety of corporate purposes, including future public offerings, to raise additional capital or to facilitate acquisitions. The Delaware General Corporation Law does not require stockholder approval for any issuance of authorized shares. However, the listing requirements of the New York Stock Exchange, which apply so long as our common stock is listed on the New York Stock Exchange, require stockholder approval of certain issuances equal to or exceeding 20% of the then outstanding voting power or then outstanding number of shares of common stock.

Our common stock is listed on the New York Stock Exchange under the symbol "WPX."

Each share of our common stock entitles its holder to one vote in the election of each director. No share of our common stock affords any cumulative voting rights. This means that the holders of a majority of the voting power of the shares voting for the election of directors can elect all directors to be elected if they choose to do so, subject to any voting rights granted to holders of any preferred stock. Generally, except as discussed in "—Anti-Takeover Effects of Certificate of Incorporation and Bylaws Provisions," all matters to be voted on by stockholders must be approved by a majority of the total voting power of the common stock present in person or represented by proxy at a meeting at which a quorum exists, subject to any voting rights granted to holders of any preferred stock. Except as otherwise provided by law or in the amended and restated certificate of incorporation (as further discussed in "—Anti-Takeover Effects of Certificate of Incorporation and Bylaws Provisions"), and subject to any voting rights granted to holders of any outstanding preferred stock, amendments to the amended and restated certificate of incorporation must be approved by a majority of the votes entitled to be cast by the holders of common stock.

Subject to the rights, if any, of holders of any outstanding series of preferred stock, holders of our common stock are entitled to dividends in such amounts and at such times as our board of directors in its discretion may declare out of funds legally available for the payment of dividends. Dividends on our common stock will be paid at the discretion of our board of directors after taking into account various factors, including:

On liquidation, dissolution or winding up of WPX, after payment in full of the amounts required to be paid to holders of preferred stock, if any, all holders of common stock are entitled to receive the same amount per share with respect to any distribution of assets to holders of shares of common stock.

No shares of common stock are subject to redemption or have preemptive rights to purchase additional shares of our common stock or other securities.

Our amended and restated certificate of incorporation authorizes our board of directors to establish one or more series of preferred stock. Unless required by law or by any stock exchange on which our common stock is listed, the authorized shares of preferred stock will be available for issuance without further action by our stockholders. Our board of directors is able to determine, with respect to any series of preferred stock, the terms and rights of that series, including the following:

The preferred stock may be issued from time to time in one or more series. The particular terms of each series being offered will be described in the prospectus supplement relating to that series of preferred stock. You should also refer to our amended and restated certificate of incorporation and to the certificate of designations relating to the series of the preferred stock being offered for the complete terms of that series of preferred stock. The certificate of designations with respect to each series of preferred stock offered will be incorporated by reference as an exhibit to the registration statement of which this prospectus forms a part. Each series of preferred stock will, when issued

against full payment of the purchase price relating to a series of preferred stock, be fully paid and nonassessable.

Some provisions of our amended and restated certificate of incorporation and amended and restated bylaws could make the following more difficult:

These provisions, summarized below, are expected to discourage coercive takeover practices and inadequate takeover bids. These provisions also are designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors. We believe that the benefits of the potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure our company outweigh the disadvantages of discouraging those proposals because negotiation of them could result in an improvement of their terms.

A director nominee shall be elected to our board of directors if the votes cast for such nominee's election exceed the votes cast against such nominee's election. Our amended and restated certificate of incorporation requires that directors may only be removed by the affirmative vote of not less than 75% of votes entitled to be cast by the outstanding capital stock in the election of our board of directors.

Our amended and restated certificate of incorporation provides that the number of directors on our board of directors will be fixed exclusively by our board of directors. Newly created directorships resulting from any increase in our authorized number of directors will be filled solely by the vote of our remaining directors in office. Any vacancies in our board of directors resulting from death, resignation, retirement, disqualification, removal from office or other cause will be filled solely by the vote of our remaining directors in office.

Our amended and restated certificate of incorporation does not provide for our stockholders to act by written consent.

Our amended and restated certificate of incorporation and amended and restated bylaws provide that a special meeting of our stockholders may be called only by (i) our board of directors or (ii) the chairman of our board of directors or our chief executive officer, in each case with the concurrence of a majority of our board of directors.

Our amended and restated certificate of incorporation and amended and restated bylaws provide that the provisions of our bylaws relating to the calling of meetings of stockholders, notice of meetings of stockholders, stockholder action by written consent, advance notice of stockholder business or director nominations, the authorized number of directors, the classified board structure, the filling of director vacancies or the removal of directors (and any provision relating to the amendment of any of

these provisions) may only be amended by the vote of a majority of our entire board of directors or by the vote of holders of at least 75% of the votes entitled to be cast by the outstanding capital stock in the election of our board of directors.

The amendment of any of the above provisions in our amended and restated certificate of incorporation requires approval by the vote of a majority of our entire board of directors followed by the vote of holders of at least 75% of the votes entitled to be cast by the outstanding capital stock in the election of our board of directors.

Requirements for Advance Notification of Stockholder Nominations and Proposals

Our amended and restated bylaws establish advance notice procedures with respect to stockholder proposals and nomination of candidates for election as directors other than nominations made by or at the direction of our board of directors or a committee of our board of directors.

Our amended and restated certificate of incorporation and amended and restated bylaws do not provide for cumulative voting in the election of directors.

The authorization of our undesignated preferred stock makes it possible for our board of directors to issue our preferred stock with voting or other rights or preferences that could impede the success of any attempt to change control of us. These and other provisions may have the effect of deferring hostile takeovers or delaying changes of control of our management.

We are subject to Section 203 of the Delaware General Corporation Law (the "DGCL"). Subject to specific exceptions, Section 203 prohibits a publicly held Delaware corporation from engaging in a "business combination" with an "interested stockholder" for a period of three years after the date of the transaction in which the person became an interested stockholder, unless:

"Business combinations" include mergers, asset sales and other transactions resulting in a financial benefit to the "interested stockholder." Subject to various exceptions, an "interested stockholder" is a person who, together with his or her affiliates and associates, owns, or within the previous three years did own, 15% or more of the corporation's outstanding voting stock These restrictions could prohibit or delay the accomplishment of mergers or other takeover or change in control attempts with respect to us and, therefore, may discourage attempts to acquire us.

The DGCL authorizes corporations to limit or eliminate the personal liability of directors to corporations and their stockholders for monetary damages for breaches of directors' fiduciary duties. Under our amended and restated certificate of incorporation, subject to limitations imposed by the DGCL, no director shall be personally liable to us or our stockholders for monetary damages for breach of fiduciary duty as a director, except for liability:

Our amended and restated bylaws provide that we must indemnify our directors and officers to the fullest extent authorized by the DGCL. We are also expressly authorized to advance certain expenses (including attorneys' fees and disbursements and court costs) and carry directors' and officers' insurance providing indemnification for our directors, officers and certain employees for some liabilities. We believe that these indemnification provisions and insurance are useful to attract and retain qualified directors and executive officers. There is currently no pending material litigation or proceeding involving any of our directors, officers or employees for which indemnification is sought.

Computershare Trust Company, N.A. is the transfer agent and registrar for our common stock.

We may offer the debt securities from time to time as senior debt. The debt securities will be issued under the indenture, dated as of September 8, 2014, between us and The Bank of New York Mellon Trust Company, N.A., as trustee. The terms of the indenture are also governed by certain provisions of the Trust Indenture Act of 1939 (the "Trust Indenture Act").

The debt securities may be issued from time to time in one or more series. The particular terms of each series which is offered by a prospectus supplement will be described in the related prospectus supplement.

We have summarized the material terms of the indenture below. The indenture has been incorporated by reference as an exhibit to the registration statement. See "Where You Can Find Additional Information; Incorporation of Certain Documents by Reference." You should read the indenture for provisions that may be important to you. Whenever we refer in this prospectus or in the related prospectus supplement to particular sections or defined terms contained in the indenture, those sections or defined terms are incorporated by reference in this prospectus or the related prospectus supplement, as applicable.

In this section, "WPX," "we," "our," "our company" and "us" refer only to WPX Energy, Inc. and not to any of our subsidiaries.

The indenture provides that debt securities in separate series may be issued by us from time to time without limitation as to aggregate principal amount. We may specify a maximum aggregate principal amount for the debt securities of any series. We will determine the terms and conditions of the debt securities, including the maturity, principal and interest. The debt securities will be unsecured obligations of our company.

A prospectus supplement will set forth the following terms of, and information relating to, the debt securities:

If a series of debt securities is denominated in a currency or currency unit other than U.S. dollars, the prospectus supplement will specify the denomination in which the debt securities will be issued and the coin or currency in which the principal and any premium or interest on those debt securities will be payable. In addition, special U.S. federal income tax or other considerations applicable to any debt

securities which are denominated in a currency or currency unit other than U.S. dollars may be described in the applicable prospectus supplement.

The debt securities may be sold at a substantial discount below their principal amount. Special U.S. federal income tax considerations applicable to debt securities sold at an original issue discount may be described in the applicable prospectus supplement.

The indenture provides that we may not directly or indirectly consolidate with or merge with or into, or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of our assets and properties and the assets and properties of our Subsidiaries (as defined in the indenture) (taken as a whole) in one or more related transactions to another Person (as defined in the indenture), unless:

An assumption of our obligations on the debt securities and under the indenture by any successor Person might be deemed for U.S. federal income tax purposes to cause an exchange of the debt securities for new debt securities by the beneficial owners thereof, resulting in recognition of gain or

possible loss for such purposes and possibly other adverse tax consequences to the beneficial owners. You should consult your tax advisors regarding the tax consequences of such an assumption.

Unless otherwise specified in the prospectus supplement, each of the following will constitute an event of default under the indenture with respect to debt securities of any series:

In case an event of default specified in clause (1), (2) or (3) above shall occur and be continuing with respect to the debt securities of such series, holders of at least 25%, and in case an event of default specified in clause (4) or (6) (unless, in the case of clause (6), otherwise provided for in the applicable series of debt securities) above shall occur and be continuing with respect to the debt securities of such series, holders of at least a majority, in aggregate principal amount of the debt securities of such series then outstanding may declare the principal amount of all the debt securities of such series outstanding under the indenture to be due and payable immediately. If an event of default described in clause (5) above shall occur and be continuing then the principal amount of all the debt securities of such series then outstanding under the indenture shall be and become due and payable immediately, without notice or other action by any holder or the trustee, to the full extent permitted by law.

Holders of the debt securities may not enforce the indenture or the debt securities except as provided in the indenture. Subject to certain limitations, holders of a majority in principal amount of the then outstanding debt securities of such series may direct the trustee in its exercise of any trust or power with respect to the debt securities of such series. The indenture provides that the trustee may withhold notice to the holders of debt securities of any such series of any default with respect to the debt securities of such series (except in payment of principal of or interest or premium on the debt securities of such series) if the trustee considers it in the interest of holders to do so.

Holders of not less than a majority in principal amount of the debt securities of such series then outstanding by notice to the trustee may on behalf of the holders of all of the debt securities of such series, waive any past or existing default or event of default under the indenture and its consequences, except a continuing default (a) in the payment of principal of, or interest or premium, if any, on the debt securities of such series or (b) in respect of a covenant or other provision of the indenture, which under the indenture cannot be modified or amended without the consent of the holder of each outstanding debt security of such series.

We are required to deliver to the trustee annually a statement regarding compliance with the indenture.

The indenture provides that modifications and amendments may be made by us and the trustee with the consent of the holders of a majority in aggregate principal amount of the outstanding debt securities of each series affected by the modification or amendment voting as a single class. We may not make any of the following modifications or amendments to the indenture without the consent of the holder of each outstanding debt security of such series affected by the modification or amendment:

A supplemental indenture that changes or eliminates any covenant or other provision of the indenture that has been included expressly and solely for the benefit of one or more particular series of debt securities, or that modifies the rights of holders of debt securities of such series with respect to such covenant or other provision, are deemed not to affect the rights under the indenture of the holders of debt securities of any other series.

The indenture provides that we and the trustee may, at any time and from time to time, without the consent of any holders of the debt securities of any series, enter into one or more supplemental indentures, in form satisfactory to the trustee, for any of the following purposes:

The indenture provides that we may satisfy and discharge our obligations under the debt securities of any series and the indenture if:

Notwithstanding such satisfaction and discharge, our obligations to compensate and indemnify the trustee and our and the trustee's obligations to hold funds in trust and to apply such funds pursuant to the terms of the indenture with respect to the debt securities of such series, with respect to issuing temporary debt securities of such series, with respect to the registration, transfer and exchange of debt securities of such series, with respect to the replacement of mutilated, destroyed, lost or stolen debt securities of such series and with respect to the maintenance of an office or agency for payment with respect to the debt securities of such series, shall in each case survive such satisfaction and discharge.

The indenture provides that (i) we will be deemed to have paid and will be discharged from any and all obligations in respect of the debt securities of such series, and the provisions of the indenture will, except as noted below, no longer be in effect with respect to the debt securities of such series ("defeasance") and (ii) we may, with respect to debt securities of such series, omit to comply with the covenants under "—Merger, Consolidation or Sale of Assets," and (unless otherwise set forth therein) any additional covenants described in the applicable prospectus supplement, and such omission shall be deemed not to be an event of default under clause (3) of the first paragraph of "—Events of Default and Remedies" with respect to the debt securities of such series ("covenant defeasance") and provided that the following conditions shall have been satisfied:

Notwithstanding a defeasance or covenant defeasance with respect to the debt securities of such series, our obligations with respect to the following will survive until otherwise terminated or discharged under the terms of the indenture or until no debt securities of such series are outstanding:

None of any affiliate, director, officer, partner, employee, incorporator, manager or owner of our Capital Stock (as defined in the indenture), as such, will have any liability for any of our obligations under the debt securities of any series, the indenture, or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each holder of debt securities of such series by accepting a debt security waives and releases all such liability. The waiver and release are part of the

consideration for issuance of the debt securities of such series. The waiver may not be effective to waive liabilities under the federal securities laws.

Notices to holders of the debt securities of any series will be given by mail to the addresses of such holders as they appear in the security register.

We will be required to file with the trustee, within 30 days after we have filed the same with the SEC, copies of the annual reports and of the information, documents, and other reports that we are required to file with the SEC pursuant to Section 13 or Section 15(d) of the Exchange Act or pursuant to Section 314 of the Trust Indenture Act. Annual reports, information, documents and reports that are filed by us with the SEC via the EDGAR system or any successor electronic delivery procedure will be deemed to be filed with the trustee at the time such documents are filed via the EDGAR system or such successor procedure. Delivery of such reports, information and documents to the trustee is for informational purposes only, and the trustee's receipt of such will not constitute constructive notice of any information contained therein or determinable from information contained therein, including our compliance with any of our covenants in the indenture.

We or the trustee may treat the registered owner of any registered debt security as the owner thereof (whether or not the debt security shall be overdue and notwithstanding any notice to the contrary) for the purpose of making payment and for all other purposes.

The indenture and the debt securities will be governed by, and construed in accordance with, the laws of the State of New York. The indenture is subject to the provisions of the Trust Indenture Act that are required to be a part of the indenture and shall, to the extent applicable, be governed by those provisions.

The Bank of New York Mellon Trust Company, N.A. is the trustee under the indenture. If the trustee becomes a creditor of ours, the indenture limits its right to obtain payment of claims in certain cases or to realize on certain property received in respect of any such claim as security or otherwise. The trustee will be permitted to engage in other transactions; however, if the trustee acquires any conflicting interest (as defined in the Trust Indenture Act) after a default has occurred and is continuing, it must eliminate such conflict within 90 days, apply to the Securities and Exchange Commission for permission to continue or resign.

The holders of a majority in principal amount of the then outstanding debt securities of a series, will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the trustee with respect to the debt securities of such series, subject to certain exceptions. The indenture provides that in case an event of default occurs and is continuing, the trustee will be required, in the exercise of its power, to use the degree of care of a prudent person in the conduct of such person's own affairs. Subject to such provisions, the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request of any holder of debt securities of a series, unless such holder has offered to the trustee security or indemnity satisfactory to it against any loss, liability or expense.

Unless otherwise indicated in the applicable prospectus supplement, the following is a summary of certain considerations associated with the purchase of the securities offered under this prospectus by employee benefit plans that are subject to Title I of the U.S. Employee Retirement Income Security Act of 1974, as amended ("ERISA"), plans, individual retirement accounts and other arrangements that are subject to Section 4975 of the Internal Revenue Code of 1986, as amended (the "Code") or provisions under any federal, state, local, non-U.S. or other laws or regulations that are similar to such provisions of the Code or ERISA (collectively, "Similar Laws"), and entities whose underlying assets are considered to include "plan assets" of any such plan, account or arrangement (each, a "Plan").

ERISA and the Code impose certain duties on persons who are fiduciaries of a Plan subject to Title I of ERISA or Section 4975 of the Code (an "ERISA Plan") and prohibit certain transactions involving the assets of an ERISA Plan and its fiduciaries or other interested parties. Under ERISA and the Code, any person who exercises any discretionary authority or control over the administration of such an ERISA Plan or the management or disposition of the assets of such an ERISA Plan, or who renders investment advice for a fee or other compensation to such an ERISA Plan, is generally considered to be a fiduciary of the ERISA Plan.

In considering an investment in the securities to be offered under this prospectus of a portion of the assets of any Plan, a fiduciary should determine whether the investment is in accordance with the documents and instruments governing the Plan and the applicable provisions of ERISA, the Code or any Similar Law relating to a fiduciary's duties to the Plan including, without limitation, the prudence, diversification, delegation of control and prohibited transaction provisions of ERISA, the Code and any other applicable Similar Laws.

Section 406 of ERISA and Section 4975 of the Code prohibit ERISA Plans from engaging in specified transactions involving plan assets with persons or entities who are "parties in interest," within the meaning of ERISA, or "disqualified persons," within the meaning of Section 4975 of the Code, unless an exemption is available. A party in interest or disqualified person who engaged in a non-exempt prohibited transaction may be subject to excise taxes and other penalties and liabilities under ERISA and the Code. In addition, the fiduciary of the ERISA Plan that engaged in such a non-exempt prohibited transaction may be subject to penalties and liabilities under ERISA and the Code. The acquisition and/or holding of securities to be offered under this prospectus by an ERISA Plan with respect to which any of the issuer, the underwriter, or their affiliates is considered a party in interest or a disqualified person may constitute or result in a direct or indirect prohibited transaction under Section 406 of ERISA and/or Section 4975 of the Code, unless the investment is acquired and is held in accordance with an applicable statutory, class or individual prohibited transaction exemption. In this regard, the U.S. Department of Labor (the "DOL") has issued prohibited transaction class exemptions, or "PTCEs," that may apply to the acquisition and holding of the securities to be offered under this prospectus. These class exemptions include, without limitation, PTCE 84-14 respecting transactions determined by independent qualified professional asset managers, PTCE 90-1 respecting insurance company pooled separate accounts, PTCE 91-38 respecting bank collective investment funds, PTCE 95-60 respecting life insurance company general accounts and PTCE 96-23 respecting transactions determined by in-house asset managers. In addition, Section 408(b)(17) of ERISA and Section 4975(d)(20) of the Code provide relief from the prohibited transaction provisions of ERISA and Section 4975 of the Code for certain transactions, provided that neither the issuer of the securities to be offered under this prospectus nor any of its affiliates (directly or indirectly) have or exercise any discretionary authority or control or render any investment advice with respect to the assets of any

ERISA Plan involved in the transaction and provided further that the ERISA Plan pays no more than adequate consideration in connection with the transaction. There can be no assurance that all of the conditions of any such exemptions will be satisfied.

Because of the foregoing, the securities to be offered under this prospectus should not be purchased or held by any person investing "plan assets" of any Plan, unless such purchase and holding will not constitute a non-exempt prohibited transaction under ERISA and the Code or similar violation of any applicable Similar Laws.

Accordingly, by acceptance of a security, each purchaser and subsequent transferee of a security will be deemed to have represented and warranted that either (i) no portion of the assets used by such purchaser or transferee to acquire and hold the securities constitutes assets of any Plan or (ii) the purchase and holding of the securities by such purchaser or transferee will not constitute a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or similar violation under any applicable Similar Laws.

The foregoing discussion is general in nature and is not intended to be all inclusive. Due to the complexity of these rules and the penalties that may be imposed upon persons involved in non-exempt prohibited transactions, it is particularly important that fiduciaries, or other persons considering purchasing the securities on behalf of, or with the assets of, any Plan, consult with their counsel regarding the potential applicability of ERISA, Section 4975 of the Code and any Similar Laws to such investment and whether an exemption would be applicable to the purchase and holding of the securities.

We may offer and sell these securities to or through one or more underwriters, dealers and agents, or directly to purchasers, on a continuous or delayed basis. We will provide the specific plan of distribution for any securities to be offered in supplements to this prospectus.

Gibson, Dunn & Crutcher LLP will pass upon the validity of the securities offered by this registration statement, unless otherwise indicated in the applicable prospectus supplement. If certain legal matters in connection with an offering of the securities made by this prospectus and a related prospectus supplement are passed on by counsel for the underwriters of such offering, that counsel will be named in the applicable prospectus supplement related to that offering.

The consolidated financial statements of WPX Energy, Inc. appearing in WPX Energy, Inc.'s Annual Report (Form 10-K) for the year ended December 31, 2016, including the schedule appearing therein, and the effectiveness of WPX Energy, Inc.'s internal control over financial reporting as of December 31, 2016, have been audited by Ernst & Young LLP, independent registered public accounting firm, as set forth in their reports thereon included therein, and incorporated herein by reference. Such financial statements are, and audited financial statements to be included in subsequently filed documents will be, incorporated herein in reliance upon the reports of Ernst & Young LLP pertaining to such financial statements and the effectiveness of our internal control over financial reporting as of the respective dates (to the extent covered by consents filed with the Securities and Exchange Commission) given on the authority of such firm as experts in accounting and auditing.

Approximately 98 percent of our year-end 2016 U.S. proved reserves estimates included in WPX Energy, Inc.'s Annual Report (Form 10-K) for the year ended December 31, 2016 were audited by Netherland, Sewell & Associates, Inc., an independent petroleum engineering firm. The description of the audit of such estimates is incorporated by reference into this prospectus upon the authority of said firm as an expert in these matters.

Conflicts of Interest		Absent a Special Mandatory Redemption Event, affiliates of certain of the underwriters may receive at least 5% of the net proceeds of this offering in connection with the repayment of all remaining amounts outstanding under the Felix Debt Facilities. See "Use of Proceeds." Accordingly, this offering is being made in compliance with the requirements of FINRA Rule 5121. Because such underwriters are not primarily responsible for managing this offering, pursuant to Rule 5121, the appointment of a qualified independent underwriter is not necessary. Pursuant to FINRA Rule 5121, such underwriters will not confirm sales of the notes to any account over which they exercise discretionary authority without the prior written approval of the customer.
