Note 1. Basis of Pro Forma Presentation

These financial statements present our unaudited pro forma balance sheet as of December 31, 2021 and our unaudited pro forma statement of operations for the year ended December 31, 2021. These unaudited statements have been prepared in accordance with Article 11 and have been developed by applying pro forma adjustments to our historical financial statements to give effect to the Veritas Acquisition.

The unaudited pro forma financial statements are for illustrative and informational purposes only and are not intended to represent or be indicative of what our results of operations would have been had the Veritas Acquisition and related financing for the transaction occurred as of or on the dates indicated. The unaudited pro forma financial statements also should not be considered representative of our future results of operations.

The pro forma adjustments related to the Veritas Acquisition and related financing for the transaction are based on preliminary estimates, accounting judgments and currently available information and assumptions that management believes are reasonable and are subject to change. Accordingly, these pro forma adjustments are preliminary and have been made solely for the purpose of providing these unaudited pro forma financial statements. Differences between these preliminary estimates and the final acquisition accounting may occur and these differences could be material. The differences, if any, could have a material impact on the accompanying unaudited pro forma financial statements and our future results of operations.

The unaudited pro forma financial statements have been derived from and should be read together with:

• the accompanying notes to the unaudited pro forma financial statements;

• our historical financial statements and the related notes contained in the Company’s Annual Report on Form 10-K for the year ended December 31 2021; and

• the historical financial statements and related notes for the assets acquired from Veritas for the year ended December 31, 2021.

The pro forma basic and diluted earnings per share amounts presented in the unaudited pro forma statement of operations are based on the weighted average number of the Company’s shares outstanding, assuming the Veritas Acquisition occurred at the beginning of the earliest period presented.

The pro forma adjustments related to the purchase price allocation of the Veritas Acquisition are preliminary and are subject to revisions as additional information becomes available. Revisions to the preliminary purchase price allocation may have a significant impact on the pro forma amounts. The pro forma adjustments related to the Veritas Acquisition reflect the fair values of the assets acquired as of January 27, 2022 (the closing date of the transaction). The pro forma adjustments do not necessarily reflect the fair values that would have been recorded if the acquisition had occurred on January 1, 2021.

Note 2. Estimated Consideration and Preliminary Purchase Price Allocation

The Company has performed a preliminary valuation analysis of the fair value of the acquired assets. Using the total consideration for the Veritas Acquisition, the Company has estimated the allocation to such assets. The following table summarizes the allocation of the preliminary purchase price as of the transaction’s closing date, January 27, 2022:

(In thousands)
Proved Properties	$	405,351
Unproved Properties	26,262
Total Assets Acquired	431,613
Asset Retirement Obligations Assumed	(2,146)
Net Assets Acquired	$	429,467
Cash Purchase Consideration	$	411,597
Fair Value of Warrants Issued	17,870
Total Estimated Purchase Price	$	429,467

This preliminary purchase price allocation has been used to prepare the transaction accounting adjustments in the pro forma balance sheet and statement of operations. The final purchase price allocation will be determined when the Company has completed the detailed valuations and necessary calculations. The final allocation is expected to be completed when the Company files its report on Form 10-K for the year ended December 31, 2022 and could differ materially from the preliminary allocation used in the transaction accounting adjustments. The final allocation may include changes in fair values of proved and unproved properties.

The pro forma financial statements do not include any pro forma income tax adjustments, due to the taxable loss position and a full valuation allowance on the deferred tax assets.

Note 3. Pro Forma Adjustments and Assumptions

The accompanying unaudited pro forma financial statements reflect the following pro forma adjustments:

(a)Reflects the consideration transferred and the preliminary purchase price allocation for the Veritas Acquisition consisting of:

i.the total cash consideration paid to Veritas of $411.6 million, which consists of a cash payment of $370.9 million and the release of the $40.7 million acquisition deposit recorded for the Veritas Acquisition as of December 31, 2021, which was released to Veritas at closing;

ii.the $17.9 million fair value of the warrants to purchase 1,939,998 shares of the Company’s common stock which were issued as part of the purchase consideration and determined to be equity-classified;

iii.the elimination of historical assets, liabilities, and members’ capital related to the Veritas Acquisition that we are not acquiring or assuming;

iv.the recognition of the incremental fair value of the acquired Veritas proved and unproved oil and natural gas properties based on the preliminary allocation of the purchase price to these properties of $431.6  million; and

v.the recognition of the incremental fair value of the assumed Veritas asset retirement obligations on the proved properties acquired based on the preliminary allocation of the purchase price to the assumed liabilities of $2.1 million.

(b) Represents the cash payment and retained earnings impact for the transaction costs incurred in conjunction with the Veritas Acquisition that have not yet been recognized in the historical period.

(c) Represents additional borrowings of $370.9 million under the Company’s existing revolving credit facility which were drawn to fund the cash payment associated with the acquisition of Veritas.

(d) Represents the adjustment to conform the “Gain (Loss) on Derivative Instruments, Net” of historical Veritas, who had previously elected presentation through “Other Income and Expense,” to present through the historical Northern Oil and Gas election as “Revenue”.

(e) Represents the expense recognized for incremental transaction costs incurred in conjunction with the Veritas Acquisition.

(f) Represents the increase in depletion expense computed on a unit of production basis following the preliminary purchase price allocation to proved and unproved oil and natural gas properties, as if the Veritas Acquisition was consummated on January 1, 2021.

(g) Represents the increase in accretion expense attributable to the assumed Veritas asset retirement obligations on the proved properties acquired based on the preliminary purchase price allocation of $2.1 million, as if the Veritas Acquisition was consummated on January 1, 2021.

(h) Represents the increase to interest expense resulting from the interest on the additional borrowings under the Company’s existing revolving credit facility that were used to finance the acquisition based on an assumed combined interest rate of 3.02%, which reflects the Company’s current estimated variable rate under the interest rate provisions of the revolving credit facility. A 1/8 of a percent point increase or decrease in the benchmark rate would result in a change in interest expense of approximately $0.5 million for the year ended December 31, 2021.

(i) Represents an expense related to the Class B Units profit-sharing arrangement resulting from the entrance into the PSA, which is included in general and administrative expense. This is a non-recurring expense and therefor was eliminated as a pro forma adjustment.

Note 3. Earnings per Share

The pro forma financial statements reflect a net loss attributable to common shareholders and therefore the 1,939,998 shares of the Company’s common stock underlying the warrants issued as purchase consideration were excluded from the computation of pro forma diluted net loss as including them would have had an anti-dilutive effect.

Supplemental Pro Forma Combined Oil and Natural Gas

Reserve and Standardized Measure Information (Unaudited)

The following unaudited supplemental pro forma oil and natural gas reserve tables present how the combined oil and natural gas reserves and standardized measure information of the Company and Veritas Acquisition may have appeared had the Veritas Acquisition occurred on January 1, 2021. The supplemental pro forma combined oil and natural gas reserves and standardized measure information are for illustrative purposes only. Numerous uncertainties are inherent in estimating quantities and values of proved reserves including future rates of production, exploration and development expenditures, commodity prices, and service costs which may affect the reserve volumes attributable to the Properties and the standardized measure of discounted future net cash flows.

The following tables provide a summary of the changes in estimated proved reserves for the year ended December 31, 2021, as well as pro forma proved developed and proved undeveloped reserves as of the beginning and end of the year, giving effect to the Veritas Acquisition as if it had occurred on January 1, 2021. The pro forma standardized measure does not include future income taxes attributable to Veritas because it is considered a pass-through entity for tax purposes.
