Exhibit 99.3

Matador Resources Company

Unaudited Pro Forma Condensed Combined Financial Information

On September 18, 2024, MRC Toro, LLC (“Purchaser”), a wholly-owned subsidiary of Matador Resources Company (“Matador”), consummated the previously disclosed acquisition (the “Ameredev Acquisition”) contemplated by that certain Securities Purchase Agreement, dated as of June 12, 2024 (the “Purchase Agreement”), among Purchaser, MRC Energy Company (“MRC Energy”) (solely for the purposes of guaranteeing the obligations of Purchaser), Ameredev II Parent, LLC (“Ameredev Parent”), Ameredev Intermediate II, LLC (“Ameredev Intermediate” and, together with Ameredev Parent, each a “Seller” and collectively, the “Sellers”) and Ameredev Stateline II, LLC (“Ameredev”), pursuant to which, among other things, Sellers agreed to sell to Purchaser, and Purchaser agreed to purchase from Sellers, all of the issued and outstanding membership interests of the Ameredev, for an amount in cash equal to $1.905 billion (subject to certain customary adjustments, including for working capital and for title defects and environmental defects). Ameredev and its subsidiaries own (i) certain oil and natural gas producing properties and undeveloped acreage located in Lea County, New Mexico and Loving and Winkler Counties, Texas and (ii) an approximate 19% stake in the parent company of Piñon Midstream, LLC, which has midstream assets in southern Lea County, New Mexico. The effective date of the Ameredev Acquisition was June 1, 2024.

Upon the closing of the Ameredev Acquisition, Purchaser paid the as-adjusted closing purchase price of approximately $1.831 billion in cash, which amount is subject to customary post-closing adjustments, of which $95.25 million was deposited in escrow in connection with the execution of the Purchase Agreement. The purchase price for the Ameredev Acquisition was funded by a combination of cash on hand and borrowings under the Company’s existing secured revolving credit facility (the “Credit Agreement”), which was amended on September 18, 2024 to, among other things: (i) provide for a term loan of $250.0 million, the full amount of which was borrowed to fund the Ameredev Acquisition, and (ii) increase the elected borrowing commitments under the revolving credit facility from $1.50 billion to $2.25 billion.

The Ameredev Acquisition was accounted for under the acquisition method of accounting for business combinations in accordance with Accounting Standards Codification Topic 805, Business Combinations (“ASC 805”). Under the acquisition method of accounting, the purchase price is allocated to the underlying tangible and intangible assets acquired and liabilities assumed based upon their estimated fair values as of the acquisition date, with any excess purchase price allocated to goodwill. Matador has made a preliminary allocation of the purchase price to the assets acquired and liabilities assumed as of the acquisition date of September 18, 2024, which is based on Matador’s preliminary valuation of the tangible and intangible assets acquired and liabilities assumed using information currently available. A final determination of the fair value of the assets and liabilities acquired in the Ameredev Acquisition will be based on an analysis of Ameredev’s actual assets and liabilities as of the closing date. Such analysis has not been completed at this time. As a result, the unaudited pro forma purchase price adjustments related to the Ameredev Acquisition are preliminary and subject to further adjustments as additional information becomes available and as additional analyses are performed. The final valuation of assets acquired and liabilities assumed may be materially different than the estimated values assumed in the unaudited pro forma condensed combined financial statements (the “pro forma financial statements”). Costs directly related to the Ameredev Acquisition are expensed in the period in which they are incurred. The pro forma financial statements presented herein have been prepared to reflect the transaction accounting adjustments to Matador’s historical condensed consolidated financial information in order to account for the Ameredev Acquisition, the assumption of assets and liabilities acquired in the Ameredev Acquisition and the additional debt incurred to fund the Ameredev Acquisition.

The Unaudited Pro Forma Condensed Combined Balance Sheet as of June 30, 2024 gives effect to the Ameredev Acquisition and the related financing as if each had been completed on June 30, 2024. The Unaudited Pro Forma Condensed Combined Statements of Operations for the year ended December 31, 2023, and the six months ended June 30, 2024, give effect to the Ameredev Acquisition and the related financing as if each had been completed on January 1, 2023. Assumptions and estimates underlying the pro forma adjustments are described in the accompanying notes, which should be read in conjunction with the pro forma financial statements.

The pro forma financial statements and related notes have been prepared by management in accordance with Article 11 of Regulation S-X, are provided for illustrative purposes only and do not purport to represent what the actual consolidated results of operations or the consolidated financial position of Matador would have been had the Ameredev Acquisition and the related financing occurred on the dates noted above, nor are they necessarily indicative of future consolidated results of operations or consolidated financial position. Future results may vary significantly from the results reflected because of various factors. The

Unaudited Pro Forma Condensed Combined Financial Information

pro forma adjustments are based on currently available information and certain estimates and assumptions that Matador believes provide a reasonable basis for presenting the significant effects of the Ameredev Acquisition.

The pro forma financial statements and related notes do not reflect the benefits of projected synergies, potential cost savings or the costs that may be necessary to achieve such savings, opportunities to increase revenue generation or other factors that may result from the Ameredev Acquisition and, accordingly, do not attempt to predict or suggest future results. Management cannot identify the timing, nature and amount of such savings, costs or other factors, any of which could affect the future consolidated results of operations or consolidated financial position of the Company.

The unaudited pro forma financial statements have been developed from and should be read in conjunction with:

•The audited consolidated financial statements and accompanying notes of Matador contained in Matador’s Annual Report on Form 10-K for the year ended December 31, 2023;

•The unaudited condensed consolidated financial statements and accompanying notes of Matador contained in Matador’s Quarterly Report on Form 10-Q for the six months ended June 30, 2024;

•The audited consolidated financial statements and related notes of Ameredev for the year ended December 31, 2023, which are filed as Exhibit 99.1 to the Current Report on Form 8-K/A; and

•The unaudited condensed consolidated financial statements and related notes of Ameredev for the six months ended June 30, 2024, which are filed as Exhibit 99.2 to the Current Report on Form 8-K/A.

Unaudited Pro Forma Condensed Combined Financial Information

1. Basis of Presentation

The accompanying unaudited pro forma condensed combined financial information was prepared based on, and should be read in conjunction with, (i) the audited historical consolidated financial statements of Matador and the audited historical consolidated financial statements of Ameredev, in each case, as of and for the year ended December 31, 2023, and (ii) the unaudited historical condensed consolidated financial statements of Matador and the unaudited historical consolidated financial statements of Ameredev, in each case, as of and for the six months ended June 30, 2024. The Ameredev Acquisition has been accounted for as a business combination in accordance with ASC 805. The fair value of the consideration paid by Matador and allocation of that amount to the underlying assets acquired and liabilities assumed was recorded by Matador as of the date of the closing of the Ameredev Acquisition. Costs directly related to the Ameredev Acquisition are expensed as incurred.

The Unaudited Pro Forma Condensed Combined Statements of Operations for the year ended December 31, 2023 and the six months ended June 30, 2024 were prepared assuming the Ameredev Acquisition and the related financing occurred on January 1, 2023. The Unaudited Pro Forma Condensed Combined Balance Sheet as of June 30, 2024 was prepared as if the Ameredev Acquisition and the related financing occurred on June 30, 2024.

The unaudited pro forma condensed combined financial information and related notes are presented for illustrative purposes only and do not purport to represent what the actual consolidated results of operations or the consolidated financial position of Matador would have been had the Ameredev Acquisition and the related financing occurred on the dates noted above, nor are they necessarily indicative of future consolidated results of operations or consolidated financial position. If the Ameredev Acquisition, the related financing and the other transactions contemplated by the Purchase Agreement had occurred in the past, the Company’s operating results might have been materially different from those presented in the unaudited pro forma condensed combined financial information. The unaudited pro forma condensed combined financial information should not be relied upon as an indication of operating results that the Company would have achieved if the Ameredev Acquisition, the related financing and the other transactions contemplated by the Purchase Agreement had taken place on the dates noted above. In addition, future results may vary significantly from the results reflected in the unaudited pro forma condensed combined financial statement of operations and should not be relied upon as an indication of the future results the Company will have after the consummation of the Ameredev Acquisition and the other transactions contemplated by the Purchase Agreement. The pro forma adjustments are based on currently available information and certain estimates and assumptions that Matador believes provide a reasonable basis for presenting the significant effects of the Ameredev Acquisition.

2. Consideration and Purchase Price Allocation

The preliminary allocation of the total purchase price in the Ameredev Acquisition 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 18, 2024, the closing date of the transaction, using the latest available information. Due to the unaudited pro forma condensed combined financial information being prepared based on preliminary estimates of the net assets acquired and balances as of June 30, 2024, the final purchase price allocation and the resulting effect on financial position and results of operations may differ significantly from the pro forma amounts included herein.

As of the date of this filing, the valuation of assets acquired and liabilities assumed remains ongoing and adjustments may be made. The Company expects to complete the final purchase price allocation during the 12-month period subsequent to the Ameredev Acquisition closing date.

Unaudited Pro Forma Condensed Combined Financial Information

The consideration transferred and the preliminary fair value of assets acquired and liabilities assumed by Matador are as follows (in thousands):


Consideration			Allocation


Cash consideration given			$1,831,214

Allocation of purchase price
Current assets			$57,279
Oil and natural gas properties
Evaluated			1,258,433
Unproved and unevaluated			369,258
Midstream properties			125,860


Investment in affiliate			115,000
Current liabilities			(88,283)
Asset retirement obligations			(6,333)

Net assets acquired			$1,831,214

The fair value measurements of assets acquired and liabilities assumed are based on inputs that are not observable in the market and therefore represent Level 3 inputs. The fair value of evaluated oil and natural gas properties and asset retirement obligations were measured using the discounted cash flow technique of valuation.

Significant unobservable inputs included future commodity prices adjusted for differentials, projections of estimated quantities of recoverable reserves, forecasted production based on decline curve analysis, estimated timing and amount of future operating and development costs, and a weighted average cost of capital.

3. Adjustments to Unaudited Pro Forma Condensed Combined Balance Sheet and Unaudited Pro Forma Condensed Combined Statements of Operations

The unaudited pro forma condensed combined financial information has been compiled in a manner consistent with the accounting policies adopted by Matador. Actual results may differ materially from the assumptions and estimates contained herein.

The pro forma adjustments are based on currently available information and certain estimates and assumptions that Matador believes provide a reasonable basis for presenting the significant effects of the Ameredev Acquisition. General descriptions of the pro forma adjustments are provided below.

The following reclassifications and adjustments were made in the preparation of the Unaudited Pro Forma Condensed Combined Balance Sheet as of June 30, 2024:

(a) Adjustment to remove assets, liabilities and equity not acquired as part of the Ameredev Acquisition.

(b) Adjustment to eliminate the historical book value of Ameredev’s assets and liabilities as of June 30, 2024 when the historical book value is different than the fair value on the date of the acquisition.

(c) Adjustment to reflect the preliminary allocation of the estimated fair value of assets acquired in the Ameredev Acquisition and the adjustment to increase the related asset retirement obligations, which was required to conform cost of abandonment and other key assumptions with those of Matador.

(d) Adjustment to record consideration and changes in working capital for the Ameredev Acquisition, including cash and the $1.825 billion in new borrowings under the credit facility, which includes a $250.0 million term loan.

Unaudited Pro Forma Condensed Combined Financial Information

(e) Reclassification to conform Ameredev’s assets and liabilities presentation to the presentation of assets and liabilities for Matador.

(f) Adjustment for the additional costs related to the increase in the elected commitment under the credit facility in order to finance the Ameredev Acquisition.

(g) Adjustment to retained earnings to reflect the estimated nonrecurring transaction costs related to the Ameredev Acquisition that are expected to be incurred by Matador, including advisory, legal, regulatory, accounting, valuation and other professional fees that are not capitalized.

Unaudited Pro Forma Condensed Combined Statements of Operations

The following reclassifications and adjustments were made in the preparation of the Unaudited Pro Forma Condensed Combined Statements of Operations for the Six Months Ended June 30, 2024:

(a) Reclassification to align the presentation of production and ad valorem taxes, transportation and processing expenses, water recycling expenses, depreciation, depletion, amortization and accretion and certain other income (expense) activity for Ameredev to the presentation by Matador.

(b) Adjustment to remove Ameredev’s historical interest expense prior to the Ameredev Acquisition.

(c) Adjustment to remove exploration and abandonment cost to align the presentation of such expenses by Ameredev with the full-cost method of accounting utilized by Matador.

(d) Adjustment to reflect the estimated interest expense in the periods presented with respect to the incremental borrowings necessary to finance the Ameredev Acquisition. The interest rate utilized for the six month period ended June 30, 2024 was approximately 7.67% for incremental borrowings of $1.825 billion. A one-eighth point change in interest rates as of June 30, 2024 would change interest expense by $1.2 million for the six month period ended June 30, 2024.

(e) Adjustment to reflect the amortization of financing costs of $14.5 million related to the increase in the elected commitment under the credit facility in order to finance the Ameredev Acquisition. Deferred financing costs are amortized straight-line over approximately 75 months, which corresponds to the March 2029 maturity date of Matador’s credit facility.

(f) Represents additional depreciation, depletion, and amortization expense and accretion of asset retirement obligation expense resulting from the change in basis of property and equipment and asset retirement obligations, respectively, acquired as a result of the Ameredev Acquisition. The depletion adjustment was calculated using the unit-of-production method under the full-cost method of accounting using estimated proved reserves and production volumes attributable to the acquired assets.

(g) Adjustment to remove derivative gains and losses that were related to derivatives not acquired as part of the Ameredev Acquisition.

(h) Adjustment to reflect the estimated incremental income tax expense that would have been recorded in the six month period ended June 30, 2024 if the Ameredev Acquisition had occurred on January 1, 2023 at Matador’s 2024 effective income tax rate of 25.52%. This effective tax rate represents the statutory federal income tax rate of 21% plus Matador’s apportioned state rate based upon the statutory Texas Margin tax rate of 0.75% and statutory New Mexico tax rate of 5.9%, which are the statutory rates in effect in those jurisdictions during 2024.

The following reclassifications and adjustments were made in the preparation of the Unaudited Pro Forma Condensed Combined Statements of Operations for the Year Ended December 31, 2023:

(b) Adjustment to remove Ameredev’s historical interest expense prior to the Ameredev Acquisition.

Unaudited Pro Forma Condensed Combined Financial Information

(c) Adjustment to remove exploration and abandonment cost to align the presentation of such expenses by Ameredev with the full-cost method of accounting utilized by Matador.

(d) Adjustment to reflect the estimated interest expense in the periods presented with respect to the incremental borrowings necessary to finance the Ameredev Acquisition. The interest rate utilized for the year ended December 31, 2023 was approximately 7.35% for incremental borrowings of $1.825 billion. A one-eighth point change in interest rates as of December 31, 2023 would change interest expense by $2.3 million for the year ended December 31, 2023.

(g) Adjustment to remove derivative gains and losses that were related to derivatives not acquired as part of the Ameredev Acquisition.

(h) Adjustment to reflect the estimated incremental income tax expense that would have been recorded in the year ended December 31, 2023 if the Ameredev Acquisition had occurred on January 1, 2023 at Matador’s 2023 effective income tax rate of 18.02%. This effective tax rate represents the statutory federal income tax rate of 21% plus Matador’s apportioned state rate based upon the statutory Texas Margin tax rate of 0.75% and statutory New Mexico tax rate of 5.9%, which are the statutory rates in effect in those jurisdictions during 2023, partially offset by permanent differences between book and taxable income.

(i) Represents the estimated nonrecurring transaction costs related to the Ameredev Acquisition that are expected to be incurred by Matador, including advisory, legal, regulatory, accounting, valuation and other professional fees that are not capitalized.

4. Supplemental Unaudited Pro Forma Combined Oil and Natural Gas Reserves and Standardized Measure Information

The following tables set forth information with respect to the historical and pro forma combined estimated oil and natural gas reserves as of December 31, 2023 for Matador and Ameredev. Ameredev reserve information has been prepared by Cawley, Gillespie & Associates, Inc., independent petroleum engineers. The following unaudited pro forma combined proved reserve information is not necessarily indicative of the results that might have occurred had the Ameredev Acquisition taken place on January 1, 2023, nor is it intended to be a projection of future results. The accuracy of any reserve estimate is a function of the quality of available data and of engineering and geological interpretation and judgment. Periodic revisions or removals of estimated reserves and future cash flows may be necessary as a result of a number of factors, including reservoir performance, new drilling, oil and natural gas prices, changes in costs, technological advances, new geological or geophysical data, changes in business strategies, or other economic factors. Accordingly, proved reserve estimates may differ significantly from the quantities of oil and natural gas ultimately recovered. For both Matador and Ameredev, the reserve estimates shown below were determined using the average first day of the month price for each of the preceding 12 months for oil and natural gas for the year ended December 31, 2023.
