Exhibit 99.3

 

Ring Energy, Inc.

Unaudited Pro Forma Condensed Combined Financial Information

 

On July 1, 2022, Ring Energy, Inc. (“Ring” or the “Company”), as buyer, and Stronghold Energy II Operating, LLC, a Delaware limited liability company (“Stronghold OpCo”) and Stronghold Energy II Royalties, LP, a Delaware limited partnership (“Stronghold RoyaltyCo”, together with Stronghold OpCo, collectively, “Stronghold”), as seller, entered into a purchase and sale agreement (the “Purchase Agreement”). Pursuant to the Purchase Agreement, Ring acquired (the “Stronghold Acquisition”) interests in oil and gas leases and related property of Stronghold consisting of approximately 37,000 net acres located in the Central Basin Platform of the Permian Basin of Texas. On August 31, 2022, Ring completed the Stronghold Acquisition pursuant to the Purchase Agreement.

 

Based on estimates as of August 31, 2022, the fair value of consideration to be paid to the seller is approximately $389.4 million, of which $167.9 million, subject to post-closing adjustments, was paid in cash at closing, $15.0 million will be payable in cash after the six-month anniversary of the closing date of the Stronghold Acquisition, and the remainder was in the form of stock consideration consisting of 21,339,986 shares of Ring common stock and 153,176 shares of newly created Series A Convertible Preferred Stock, par value $0.001 per share (“Preferred Stock”). In addition, Ring assumed derivative liabilities valued at $26.4 million as of August 31, 2022, and $1.7 million of suspense in the Stronghold Acquisition.

 

The cash portion of the purchase price was funded by amending the Company’s   existing credit facility to increase the total borrowing capacity under the credit facility to $1,000,000,000 with an initial borrowing base of approximately $600,000,000 (up from its existing $350,000,000 borrowing base).

 

When and if declared, the Preferred Stock will be entitled to preferred distributions at a rate of 8.0% per annum of the Liquidation Preference per share, which is initially $1,000 per share plus any accrued and unpaid distributions through the date of conversion, payable each calendar quarter. To the extent distributions are not declared and paid, then on each distribution date the unpaid distribution per share is added to the per share Liquidation Preference. Notwithstanding the foregoing, no distribution will be paid on the Preferred Stock if it converts into Ring common stock on or before January 31, 2023.

 

The Preferred Stock may not be converted into Ring common stock until such time as stockholder approval is received, which is defined as the date requisite approval from holders of capital stock of the Company is received as required at law or under the applicable securities exchange rules (currently the NYSE American stock exchange). Upon receiving stockholder approval, each share of issued Preferred Stock will be automatically converted into such number of shares of Ring common stock determined by dividing (i) the Liquidation Preference as of the conversion date by (ii) the conversion price, which is initially $3.60 per share based on a 20-day volume weighted average price of Ring common stock as of June 30, 2022 (subject to adjustment for stock splits and distributions, recapitalizations, exchanges and similar actions) (such calculation, as so adjusted from time to time, the “Conversion Rate”). The initial Conversion Rate is 277.7778 shares of Ring common stock for each share of Preferred Stock.

 

The Stronghold Acquisition will be accounted for as an asset acquisition in accordance with Accounting Standards Codification Topic 805, Business Combinations (“ASC 805”). The fair value of the consideration paid by Ring and the allocation of that amount to the underlying assets acquired is recorded on a relative fair value basis. Additionally, costs directly related to the Stronghold Acquisition are capitalized as a component of the purchase price. The unaudited pro forma condensed combined financial statements presented herein have been prepared to reflect the transaction accounting adjustments to Ring’s historical condensed consolidated financial information in order to account for the Stronghold Acquisition and include the assumption of liabilities as set forth in the Purchase Agreement.

 

 

 

 

The Unaudited Pro Forma Condensed Combined Balance Sheet as of June 30, 2022 gives effect to the Stronghold Acquisition as if it had been completed on June 30, 2022. The Unaudited Pro Forma Condensed Combined Statements of Operations for the six months ended June 30, 2022 and the year ended December 31, 2021 give effect to the Stronghold Acquisition as if it had been completed on January 1, 2021. Assumptions and estimates underlying the pro forma adjustments are described in the accompanying notes, which should be read in conjunction with the unaudited pro forma condensed combined financial statements.

 

The unaudited pro forma condensed combined financial information is provided for illustrative purposes only and does not purport to represent what the actual consolidated results of operations or the consolidated financial position of Ring would have been had the Stronghold Acquisition and 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. In Ring’s opinion, all adjustments that are necessary to present fairly the unaudited pro forma condensed combined financial information have been made.

 

The unaudited pro forma condensed combined financial information does not reflect the benefits of 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 Stronghold Acquisition and, accordingly, does not attempt to predict or suggest future results.

 

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

 

·The audited financial statements and accompanying notes of Ring contained in Ring’s Annual Report on Form 10-K for the year ended December 31, 2021;
   
·The unaudited condensed   financial statements and accompanying notes contained in Ring’s Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2022;

Notes to Unaudited Pro Forma Condensed Combined Financial Information

 

 

1.Basis of Presentation

 

The accompanying unaudited pro forma condensed combined financial information was prepared based on the historical financial statements of Ring and the historical consolidated financial statements of Stronghold. The Stronghold Acquisition has been accounted for as an asset acquisition in accordance with ASC 805. The fair value of the consideration paid by Ring and allocation of that amount to the underlying assets acquired, on a relative fair value basis, will be recorded on Ring’s books as of the date of the closing of the Stronghold Acquisition. Additionally, costs directly related to the Stronghold Acquisition are capitalized as a component of the purchase price.

 

The Unaudited Pro Forma Condensed Combined Statements of Operations for the Six Months Ended June 30, 2022 and the Year Ended December 31, 2021 were prepared assuming the Stronghold Acquisition occurred on January 1, 2021. The Unaudited Pro Forma Condensed Combined Balance Sheet as of June 30, 2022 was prepared as if the Stronghold Acquisition had occurred on June 30, 2022.

 

The unaudited pro forma condensed combined financial information and related notes are presented for illustrative purposes only. If the Stronghold Acquisition and other transactions contemplated herein 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 Stronghold Acquisition and other transactions contemplated herein had taken place on the specified date. 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 contemplation of the Stronghold Acquisition and the other transactions contemplated by these unaudited pro forma condensed combined financial information. In Ring’s opinion, all adjustments that are necessary to present fairly the unaudited pro forma condensed combined financial information have been made.  

 

2.Consideration and Purchase Price Allocation

 

The preliminary allocation of the total purchase price in the Stronghold 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 the closing date of the transaction using currently available information and market data as of August 31, 2022. Because the unaudited pro forma condensed 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 differ significantly from the pro forma amounts included herein.

 

The preliminary purchase price allocation is subject to change due to several factors, including but not limited to changes in the estimated fair value of assets acquired and liabilities assumed as of the closing date of the transaction, which could result from changes in future oil and natural gas commodity prices, reserve estimates, interest rates, as well as other factors.

 

 

 

 

The consideration transferred and the fair value of assets acquired and liabilities assumed by Ring are as follows (in thousands, except share amounts and stock price):

 

Consideration:    
Shares of Ring Common Stock issued   21,339,986 
Ring Common Stock price as of August 31, 2022  $3.24 
Common Stock Consideration  $69,142 
      
Shares of Ring Preferred Stock issued   153,176 
Aggregate Liquidation Preference  $153,176 
Conversion Price  $3.60 
As-Converted Shares of Ring Common Stock   42,548,903 
Ring Common Stock Price as of August 31, 2022  $3.24 
Preferred Stock Consideration  $137,858 
      
Cash consideration   167,944 
Fair value of deferred payment liability   14,417 
Fair value of consideration to be paid to seller   389,361 
      
Direct transaction costs   10,315 
Total consideration  $399,676 
      
Fair value of assets acquired:     
Oil and natural gas properties   446,105 
Amount attributable to assets acquired  $446,105 
      
Fair value of liabilities assumed:     
Suspense liability   1,652 
Derivative liabilities   26,409 
Asset retirement obligations   9,731 
Deferred income taxes   8,637 
Amount attributable to liabilities assumed  $46,429 

 

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 oil and 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 Ring. 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 Ring believes provide a reasonable basis for presenting the significant effects of the Stronghold Acquisition. General descriptions of the pro forma adjustments are provided below.

 

 

 

 

Unaudited Pro Forma Condensed Combined Balance Sheet

 

The following adjustments were made in the preparation of the Unaudited Pro Forma Condensed Combined Balance Sheet as of June 30, 2022:

 

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

 

(b)Adjustment to eliminate the historical book value and accumulated depreciation, depletion and amortization of Stronghold's oil and gas properties as of June 30, 2022.

 

(c)Adjustment to reflect the assets acquired of Stronghold, on a relative fair value basis.

 

(d)Adjustment to record new borrowings related to the cash consideration used in the Stronghold Acquisition.

 

(e)Adjustment to reflect the fair value of Stronghold’s derivative liabilities assumed as of August 31, 2022.

 

(f)Adjustment to reflect the issuance of 21,339,986 shares of Ring common stock pursuant to the Purchase Agreement.

 

(g)Adjustment to reflect the fair value of the $15.0 million deferred payment to be made in connection with the Stronghold Acquisition.

 

(h)Adjustment for the payment of deferred financing costs and transaction expenses incurred for the Stronghold Acquisition.

 

(i)Adjustment to reflect the fair value of Stronghold’s suspense liabilities assumed as of August 31, 2022.

 

(j)Adjustment to reflect the cash consideration paid for the Stronghold Acquisition.

 

(k)Adjustment to reflect asset retirement obligations associated with the Stronghold Acquisition properties.

 

(l)Adjustment to reflect deferred income taxes associated with the Stronghold Acquisition.

 

(m)Adjustment for the issuance of Preferred Stock issued pursuant to the Purchase Agreement. From the 50,000,000 shares of preferred stock authorized pursuant to the Articles of Incorporation of Ring, the Board authorized 153,176 shares of Preferred Stock to be issued as part of the Stronghold Acquisition. The Preferred Stock is required to be presented outside of permanent equity as it is redeemable for cash upon the occurrence of certain events that are not solely within the control of Ring. The adjustment is to show the movement of the Ring's existing authorized preferred stock out of permanent equity. The amount is based on the estimated issuance date fair value, which was determined based on 42,548,903 as-converted shares of Ring common stock multiplied by the August 31, 2022 Ring stock price of $3.24 per common share.

 

 

 

 

Unaudited Pro Forma Condensed Combined Statements of Operations

 

The following adjustments were made in the preparation of the Unaudited Pro Forma Condensed Combined Statements of Operations for the Six Months Ended June 30, 2022 and the Year Ended December 31, 2021:

 

(a)Adjustments to conform Stronghold’s revenue presentation to the presentation of revenues for Ring.   

 

(b)Adjustment to align the presentation of ad valorem and operating lease expense for Stronghold to the presentation by Ring.

 

(c)Adjustment to remove Stronghold’s historical other income and expense prior to the Stronghold Acquisition.

 

(d)Adjustment to remove exploration and abandonment cost to align the presentation of such expenses by Stronghold with the full cost method of accounting utilized by Ring.

 

(e)Adjustment to reflect the estimated interest expense in the periods presented with respect to the incremental borrowings necessary to finance the Stronghold Acquisition. The interest rate utilized as of June 30, 2022 was 4.294% for incremental borrowings. A one-eighth point change in interest rates as of June 30, 2022 would change interest expense by $0.1 million for the six months ended June 30, 2022 and by $0.3 million for the year ended December 31, 2021.

 

(f)Adjustment to reflect the amortization of deferred financing costs of $18.8 million related to the financing of the Stronghold Acquisition. Deferred financing costs are amortized straight-line over approximately 48 months, which corresponds to the maturity date of Ring’s amended credit facility.

 

(g)Adjustment to reflect the amortization of the discount resulting from the difference between the principal amount of the deferred payment and the original fair value recognized. The deferred payment of $15.0 million is originally recognized at its fair value of $14.4 million as part of the consideration paid in connection with the Stronghold Acquisition. 

 

(h)Represents depreciation, depletion, and amortization expense resulting from the change in basis of property and equipment acquired and accretion expense from new asset retirement obligations recognized as a result of the Stronghold 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.

 

(i)Adjustment to reflect the issuance of 21,339,986 shares of Ring common stock pursuant to the Purchase Agreement in basic earnings per share and the issuance of 42,548,903 common shares under the if-converted method for Preferred Stock in diluted earnings per share for the six months ended June 30, 2022. The following table reconciles historical and pro forma basic and diluted earnings per share for the period indicated (in thousands, except share and per share amounts):

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, 2021 for Ring and Stronghold. The reserve information of Ring has been prepared by Cawley, Gillespie & Associates, Inc., independent petroleum engineers. Stronghold reserve information has been prepared by Stronghold’s in-house petroleum engineers. The following unaudited pro forma combined proved reserve information is not necessarily indicative of the results that might have occurred had the Stronghold Acquisition taken place on January 1, 2021, 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, crude 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 crude oil and natural gas ultimately recovered. For both Ring and Stronghold 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, 2021.
