(1) Represents an estimated aggregate minimum volume commitment (“MVC”) of $21.7 million related to unfavorable contracts acquired in the Williston Basin Acquisition that the Company has determined to be probable and reasonably estimable at the close of the transaction.

(2) Prior to the closing of the Williston Basin Acquisition, the Company expensed $1.8 million of transaction costs as incurred under general and administrative expenses during the nine months ended September 30, 2021. At closing, the Company reduced general and administrative expenses by $1.8 million and recorded these costs as part of the total cost of the Williston Basin Acquisition in accordance with FASB ASC 805-50. In addition, the Company estimates it will accrue an additional $2.3 million of transaction costs that will be recorded as part of the total cost of the Williston Basin Acquisition.

The unaudited pro forma condensed consolidated combined statements of operations for the nine month period ended September 30, 2021 and the year ended December 31, 2020, as well as the unaudited pro forma condensed consolidated statements of operations for the years ended December 31, 2018 and 2019 reflect the following adjustments:

(a) Represents the classification of revenues and expenses from the OMP Merger as discontinued operations. The Company will have continuing cash outflows to Crestwood following the completion of the OMP Merger for gathering, processing, transportation and water handling costs pursuant to the existing contractual arrangements between the Company and OMP that will be assigned to Crestwood at closing. Historically, these transactions were eliminated within lease operating expenses and gathering, processing and transportation expenses for operated properties and within oil and gas revenues for non-operated properties.

(b) Represents the purchase of residue gas and natural gas liquids (“NGLs”), which were subsequently sold to third parties. The Company has historically eliminated the intercompany purchase of residue gas and NGLs from OMP in its consolidated financial statements within midstream expenses. In addition, the subsequent sale of residue gas and NGLs to third parties that was purchased from OMP has historically been reported within midstream revenues. The Company has reclassified these transactions to purchased oil and gas expenses and purchased oil and gas sales, respectively, to reflect the expected continuing impact.

The unaudited pro forma condensed consolidated combined statements of operations for the nine month period ended September 30, 2021 and the year ended December 31, 2020 reflect the following adjustments:

(d) Represents the incremental depreciation, depletion and amortization and accretion expense related to the assets acquired in the Williston Basin Acquisition. Depletion was calculated using the unit-of-production method under the successful efforts method of accounting and was adjusted for (i) the increase in depletion reflecting the acquisition cost and production volumes attributable to the oil and gas properties and (ii) the revision to the depletion rate reflecting the reserve volumes attributable to the oil and gas properties. The pro forma depletion rate attributable to the Williston Basin Acquisition was $8.47 per barrel of oil equivalent. This adjustment also includes the depreciation expense attributable to other property, plant and equipment and

accretion expense attributable to asset retirement obligations of $0.3 million and $0.6 million for the nine months ended September 30, 2021, respectively, and $0.3 million and $0.8 million for the year ended December 31, 2020, respectively.

(e) Represents the estimated impact from additional employees hired by the Company in connection with the Williston Basin Acquisition of $2.8 million for the nine months ended September 30, 2021 and $3.7 million for the year ended December 31, 2020. In addition, general and administrative expenses for the nine months ended September 30, 2021 was offset by $1.8 million of transaction costs previously expensed as incurred prior to closing of the Williston Basin Acquisition that were subsequently capitalized and recorded as part of the total cost of the Williston Basin Acquisition at closing in accordance with FASB ASC 805-50.

(g) The Company recorded a gain on sale of properties of $227.4 million from the Permian Basin Sale in its historical unaudited condensed consolidated financial statements for the nine months ended September 30, 2021. This pro forma adjustment records this gain on sale of properties in the results of operations for the year ended December 31, 2020 and removes it from the results of operations for the nine months ended September 30, 2021.

(i) Represents interest expense associated with the Oasis Senior Notes of $11.1 million and amortization of deferred financing costs of $0.7 million during the nine months ended September 30, 2021 and interest expense of $25.5 million and amortization of deferred financing costs of $1.6 million during the year ended December 31, 2020. The Company issued the Oasis Senior Notes on June 9, 2021 and used the proceeds to finance a portion of the Williston Basin Acquisition. The Company’s historical unaudited condensed consolidated financial statements already includes interest expense from the Oasis Senior Notes from June 9, 2021 until September 30, 2021.

(l) Represents the impacts to non-controlling interests from the application of fresh start accounting attributable to discontinued operations as follows: (i) net loss from fresh start adjustments attributable to non-controlling interests of $86.8 million; offset by (ii) net income from reorganization adjustments attributable to non-controlling interests of $9.1 million.

(m) Represents the immediate vesting on the Emergence Date of Predecessor restricted stock awards of $6.7 million, Predecessor performance share units of $4.7 million, Predecessor phantom unit awards of $1.0 million and unamortized prepaid cash incentives of $4.2 million that were each attributable to continuing operations.
