SandRidge’s Strategic Rationale for the Merger

SandRidge’s mission is to create resource value from its oil and natural gas development and production activities in the Mid-Continent and Rockies regions of the United States. In pursuit of its mission, SandRidge focuses on six strategies, including focusing on its complementary operating areas, preserving capital (in part by focusing drilling efforts on locations that make the most effective use of existing infrastructure), focusing on cost efficiencies and capital allocation, mitigating commodity price risk by entering into derivative contracts, maintaining flexibility (including by maintaining multi-year inventories of both oil and natural gas drilling locations) and pursuing opportunistic acquisitions.

The acquisition of Bonanza Creek pursuant to the merger is a direct continuation of these strategies. SandRidge’s existing assets in the Mid-Continent and Niobrara. are in different stages of the development cycle:

This current combination of mature Mississippi Lime assets and emerging North Park and NW STACK assets, in the absence of significant development-ready inventory, results in a higher risk profile. The expansion of SandRidge’s Niobrara position to include Bonanza Creek’s DJ Basin assets is expected to considerably improve SandRidge’s risk profile by:

SandRidge expects that these assets will allow SandRidge to accelerate returns and grow cash flow while its emerging assets progress to the development phase. The merger is expected to be immediately accretive to SandRidge’s cash flow per share and net asset value per share, while significantly reducing SandRidge’s risk profile. In addition, SandRidge will immediately take the steps necessary to achieve at least $20 million in annual general and administrative savings and will continue to focus on reducing its cost structure. The combined company is also expected to benefit by leveraging the shared experience and expertise of each other’s operational team to enhance the technical value across the Colorado Niobrara play.

To effect the transaction, SandRidge chose to use a measured balance of cash and equity and weighed increasing accretion from funding with cash against pro forma leverage and liquidity. The balance SandRidge chose of approximately 53% cash and 47% equity results in significant accretion while maintaining a prudent level of leverage which is anticipated to remain at or below 2.0x (1.9x assuming all $20.0 million in general and administrative expense savings are realized) EBITDA over the next three years.

Following the transaction, SandRidge expects greater than $300 million of liquidity at closing through a new reserve based loan with an initial borrowing base of $700 million on more favorable terms than its existing reserve based credit facility. To support the new credit facility, SandRidge’s current agent bank has delivered a highly confident letter to SandRidge supporting these terms. The increased borrowing base of $700 million versus the expected borrowing base of the combined company of $618 million provides enhanced liquidity at closing and indicates the strength of the combined company’s proved reserves.

In addition to delivering immediate accretion to cash flow per share and net asset value per share, the transaction is attractively valued. As set forth in the section entitled “The Merger—Opinion of SandRidge’s Financial Advisor,” the $36.00 per share acquisition price is well within the per share valuation ranges implied

by Bonanza Creek’s net asset value, historical trading range since emerging from bankruptcy and comparable company EBITDA and production multiples. Moreover, SandRidge expects to generate meaningful synergies, with at least $20 million of anticipated annual general and administrative savings already identified. SandRidge further expects to capture additional cost savings through operational efficiencies and to leverage the expertise of its combined operational teams to drive operational improvements across the Niobrara play.

In short, the merger is a very strategic transaction for SandRidge that is faithful to SandRidge’s existing strategy and is designed to create long term stockholder value with lower risk.

For additional information regarding the strategic rationale of the merger, see the section entitled “The Merger—Recommendation of the SandRidge Board and Reasons for the Merger.”

The Merger

Upon satisfaction or waiver of the conditions to closing in the merger agreement, on the closing date of the merger, Merger Sub, a wholly owned subsidiary of SandRidge formed for the purpose of effecting the merger,

will merge with and into Bonanza Creek, and Bonanza Creek will be the surviving corporation in the merger. At the effective time, each share of Bonanza Creek common stock issued and outstanding immediately prior to the effective time (other than excluded shares) will be converted into the right to receive (i) $19.20 in cash, without interest and subject to any required withholding taxes, and (ii) a number of shares of SandRidge common stock, equal to the quotient (referred to previously in this joint proxy statement/prospectus as the exchange ratio) determined by dividing (a) $16.80 by (b) the volume-weighted average price per share of SandRidge common stock for the 20 consecutive trading days ending on the third-to-last trading day prior to the closing date of the merger (referred to previously in this joint proxy statement/prospectus as the SandRidge average stock price); provided, however, that (x) if the SandRidge average stock price is an amount greater than $21.38, then the exchange ratio will be 0.7858, and (y) if the SandRidge average stock price is an amount less than $17.50, then the exchange ratio will be 0.9600 (such aggregate amount of cash and number of shares of SandRidge common stock is referred to previously in this joint proxy statement/prospectus as the merger consideration). If the aggregate number of shares of SandRidge common stock that a Bonanza Creek stockholder is entitled to receive as part of the merger consideration includes a fraction of a share of SandRidge common stock, such Bonanza Creek stockholder will receive cash in lieu of that fractional share.

Additionally, all Bonanza Creek warrants issued pursuant to the Bonanza Creek warrant agreement will be automatically exercised in accordance with the terms of the Bonanza Creek warrant agreement. Furthermore, the Bonanza Creek board will take those actions necessary so that at the effective time, outstanding (i) Bonanza Creek stock options, (ii) Bonanza Creek RSUs (other than any Director RSUs), and (iii) Director RSUs will respectively be treated as described in the section entitled “The Merger—Treatment of Bonanza Creek Long-Term Incentive Compensation.”

Financing of the Merger

SandRidge anticipates that the total amount of funds necessary to finance the cash portion of the merger consideration and to pay transaction fees and expenses will be approximately $428 million. This amount is expected to be funded through a combination of available cash on hand and borrowings under SandRidge’s revolving credit facility. In connection with the closing, SandRidge intends to enter into a new reserve based credit facility. The administrative agent for SandRidge’s current reserve based credit facility has delivered to SandRidge a highly confident letter supporting the terms of a new credit facility with an initial borrowing base of at least $700 million and on more favorable terms than SandRidge’s current reserve based credit facility.

Interests of Certain Bonanza Creek Directors and Executive Officers in the Merger

When considering the recommendation of the Bonanza Creek board that you vote to approve the proposal to adopt the merger agreement, you should be aware that certain members of the board of directors and executive officers of Bonanza Creek have economic interests in the merger that are different from, or in addition to, the interests of Bonanza Creek stockholders generally. The Bonanza Creek board was aware of and considered these interests to the extent that they existed at the time, among other matters, in approving the merger agreement and the merger and recommending that the merger agreement be adopted by stockholders.

Bonanza Creek’s executive officers are parties to agreements with Bonanza Creek that provide severance benefits if their employment is terminated under certain circumstances in connection with a change in control of Bonanza Creek, including the merger. Furthermore, the merger agreement provides that (i) outstanding Bonanza Creek stock options will be converted into options to acquire shares of SandRidge common stock, (ii) outstanding Bonanza Creek RSUs (other than Director RSUs) will be converted into restricted stock unit awards with respect to shares of SandRidge common stock and (iii) outstanding Director RSUs will vest in full and will be canceled and converted into the right to receive the specified merger consideration, subject to certain limitations.

For more information, see the sections entitled “The Merger—Treatment of Bonanza Creek Long-Term Incentive Compensation” and “The Merger—Interests of Certain Bonanza Creek Directors and Executive Officers in the Merger” beginning on pages 139 and 127, respectively.

Board of Directors and Management of SandRidge Following Completion of the Merger

Upon completion of the merger, the current directors and executive officers of SandRidge are expected to continue in their current positions, other than as may be publicly announced by SandRidge in the normal course. None of SandRidge’s current directors or executive officers will receive any additional compensation or have any additional rights triggered or accelerated as a result of the completion of the merger.

Pursuant to the merger agreement, SandRidge is required to take all necessary corporate action (i) so that upon and after the effective time, the size of the SandRidge board is increased by one member, (ii) to appoint to the SandRidge board one individual who has been a corporate executive with financial or operating experience in the oil and gas industry in the Rocky Mountain region of the United States, as mutually agreed upon by Bonanza Creek and SandRidge (and who must have been serving as a director of the Bonanza Creek board as of the date the merger agreement was entered into) and approved by the Nominating and Governance Committee of the SandRidge board, to fill the vacancy on the SandRidge board created by such increase at the effective time and (iii) to nominate the new director for election to the SandRidge board in the proxy statement relating to the first annual meeting of the stockholders of SandRidge following the completion of the merger with respect to which a definitive proxy statement has not been filed by SandRidge prior to the completion of the merger.

Material U.S. Federal Income Tax Consequences

The receipt of shares of SandRidge common stock and cash in exchange for Bonanza Creek common stock pursuant to the merger agreement will be a taxable transaction for U.S. federal income tax purposes to U.S. holders (as defined in the section entitled “The Merger—Material U.S. Federal Income Tax Consequences”). A U.S. holder will recognize gain or loss in an amount equal to the difference between:

Gain or loss recognized by a U.S. holder generally will be taxable as capital gain or loss.

The U.S. federal income tax consequences of the merger to any holder of Bonanza Creek common stock will depend on such holder’s own personal tax situation. Accordingly, you are strongly urged to consult your tax advisor for a full understanding of the particular tax consequences of the merger to you.

See the section entitled “The Merger—Material U.S. Federal Income Tax Consequences” for a more complete discussion of certain material U.S. federal income tax consequences of the merger

Accounting Treatment

SandRidge prepares its financial statements in accordance with generally accepted accounting principles in the United States (“GAAP”). The merger will be accounted for using the acquisition method of accounting with SandRidge being considered the acquirer of Bonanza Creek for accounting purposes. This means that SandRidge will allocate the purchase price to the fair value of Bonanza Creek’s tangible and intangible assets and liabilities at the acquisition date, with the excess purchase price (if any) being recorded as goodwill. Under the acquisition method of accounting, goodwill is not amortized but is tested for impairment at least annually.

Regulatory Approvals Required to Complete the Merger

SandRidge and Bonanza Creek have determined that the merger is not subject to the requirements of the HSR Act, and no other governmental consents are required.

Additionally, in connection with the share issuance proposal, SandRidge must file a registration statement with the SEC under the Exchange Act that is declared effective by the SEC.

Treatment of Bonanza Creek Equity Awards

At the effective time (i) outstanding Bonanza Creek stock options will be converted into options to acquire shares of SandRidge common stock, (ii) outstanding Bonanza Creek RSUs (other than Director RSUs) will be

converted into restricted stock unit awards with respect to shares of SandRidge common stock, and (iii) outstanding Director RSUs will vest in full and will be canceled and converted into the right to receive the specified merger consideration, subject to certain limitations. Additionally, the Bonanza Creek board will have adopted resolutions to adjust the terms of outstanding Bonanza Creek stock options and Bonanza Creek RSUs (other than Director RSUs) to provide for accelerated vesting in certain circumstances.

See the sections entitled “The Merger—Treatment of Bonanza Creek Long-Term Incentive Compensation” and “The Merger—Interests of Certain Bonanza Creek Directors and Executive Officers in the Merger” for a detailed description of the treatment of Bonanza Creek equity awards.

Treatment of Bonanza Creek Warrants

All Bonanza Creek warrants will be automatically exercised in accordance with the terms of the Bonanza Creek warrant agreement.

Listing of SandRidge Common Stock; Delisting of Bonanza Creek Common Stock

It is a condition to the consummation of the merger that the shares of SandRidge common stock to be issued to Bonanza Creek stockholders in the merger be authorized for listing on the NYSE, subject to official notice of issuance. As a result of the merger, shares of Bonanza Creek common stock currently listed on the NYSE will cease to be listed on the NYSE.

Appraisal Rights and Dissenters’ Rights

If the merger is completed, Bonanza Creek stockholders will be entitled to appraisal rights under Section 262 of the DGCL, provided they satisfy the special criteria and conditions set forth in Section 262 of the DGCL. Bonanza Creek common stock held by stockholders that do not vote for approval of the merger and make a demand for appraisal in accordance with Delaware law will not be converted into the right to receive the merger consideration, but will be converted into the right to receive a cash payment of the amount determined by the Delaware Court of Chancery to be the fair value of the stockholder’s shares of Bonanza Creek common stock at the effective time, together with interest on such amount from the effective time until paid. The fair value of a share of Bonanza Creek common stock at the effective time as determined by the Delaware Court of Chancery may be less than, equal to or more than the amount such holders would have received under the merger agreement.

Under the DGCL, as well as the governing documents of SandRidge, SandRidge stockholders are not entitled to dissenters’ rights in connection with the merger.

No Solicitation of Alternative Proposals

Pursuant to the merger agreement, each of SandRidge and Bonanza Creek have agreed that they will not, and will cause their respective subsidiaries and will use commercially reasonable efforts to cause their respective representatives not to, directly or indirectly, (i) initiate, solicit or knowingly encourage or knowingly facilitate (including by furnishing or providing information) any inquiries, proposals, or offers regarding, or the making of an alternative proposal or any offer that would reasonably be expected to lead to an alternative proposal, (ii) enter into, participate or engage in or continue any discussions or negotiations with respect to an alternative proposal or any inquiry or indication of interest that would reasonably be expected to lead to an alternative proposal, (iii) furnish any non-public information, or access to its properties, assets or employees, to any person in connection with or in response to an alternative proposal or any inquiry or indication of interest that would reasonably be expected to lead to an alternative proposal, (iv) approve or recommend to its stockholders, or

execute or enter into any letter of intent or agreement in principle, or other agreement with any person providing for an alternative proposal (other than certain permitted confidentiality agreements) or (v) resolve, agree or publicly propose to take any of the foregoing actions.

The parties are permitted, prior to obtaining the applicable stockholder approval contemplated by the merger agreement, to engage in the activities described in clauses (ii) and (iii) above solely with and to any person who has made a written, bona fide alternative proposal that did not result from a breach of the applicable party’s non-solicitation obligations; provided, that (i) no non-public information may be furnished until the party receives an executed confidentiality agreement containing limitations on the use and disclosure of non-public information no less favorable to that party in the aggregate than the terms of the confidentiality agreement between SandRidge and Bonanza Creek and permitting any information provided thereunder to be provided to either SandRidge or Bonanza Creek, as applicable; (ii) such party provides prior written notice to the other party of the identity of such third party and of such party’s intention to take such actions and (iii) prior to taking any such actions, the party’s board of directors or any committee thereof determines in good faith, after consultation with its financial advisors and outside legal counsel, that such alternative proposal is, or would reasonably be expected to lead to, a superior proposal, and, after consultation with its outside legal counsel, that the failure to engage in such activities would be inconsistent with the board’s duties under applicable law.

See the section entitled “The Merger Agreement—No Solicitation of Alternative Proposals” for a more detailed description and a summary of other additional obligations of SandRidge and Bonanza Creek.

Conditions to Completion of the Merger

The obligations of Bonanza Creek and SandRidge to consummate the merger are subject to the satisfaction or waiver (to the extent permissible under applicable laws) of the following mutual conditions:

The obligation of Bonanza Creek to effect the merger is also subject to the satisfaction or waiver by Bonanza Creek of the following additional conditions:

The obligations of SandRidge and Merger Sub to effect the merger are also subject to the satisfaction or waiver by SandRidge of the following additional conditions:

As further discussed under the section entitled “Risk Factors,” neither SandRidge nor Bonanza Creek can be certain when, or if, the conditions to the merger will be satisfied or waived, or that the merger will be completed.

None of SandRidge, Bonanza Creek or Merger Sub may rely, either as a basis for not consummating the merger or for terminating the merger agreement (as described below), on the failure of any condition set forth above, as the case may be, to be satisfied if such failure was caused by such party’s breach of any provision of the merger agreement.

Termination of the Merger Agreement

Bonanza Creek and SandRidge may mutually agree, in a written instrument, to terminate the merger agreement before consummating the merger.

In addition, either SandRidge or Bonanza Creek may terminate the merger agreement if:

Bonanza Creek may also terminate the merger agreement in order to enter into a definitive agreement with respect to a Bonanza Creek superior proposal subject to compliance with certain procedures set forth in the merger agreement (provided that contemporaneous with such termination Bonanza Creek tenders a termination fee payment to SandRidge).

Expenses and Termination Fees Relating to the Termination of the Merger Agreement

Bonanza Creek or SandRidge, as applicable, will be obligated to pay the other party a termination fee of $26,116,219 (in certain cases, less any amounts previously paid to the other party) in the following circumstances:

Bonanza Creek will also be required to pay a termination fee of $26,116,219 if Bonanza Creek terminates the merger agreement in order to enter into a Bonanza Creek superior proposal.

In addition, unless otherwise entitled to the $26,116,219 termination fee, SandRidge or Bonanza Creek will be obligated to pay the other party an expense reimbursement fee of up to $3,730,888 if (i) such party’s stockholders fail to adopt the merger agreement or approve the share issuance proposal, as applicable, or (ii) such party commits a terminable breach (other than with respect to a breach of the change of recommendation and non-solicitation obligations, in which case the entire $26,116,219 termination fee will be due and payable).

In no event shall either party be entitled to receive more than one termination fee and one expense reimbursement fee. If a party receives a termination fee, then such party will not be entitled to also receive an expense reimbursement fee, and any payment of the expense reimbursement fee shall be fully creditable against any subsequent payment of the termination fee.

Specific Performance

In addition to any other remedy that may be available to each party, including monetary damages, each of the parties will be entitled to an injunction or injunctions, or any other appropriate form of specific performance or equitable relief, to prevent breaches of the merger agreement and to enforce specifically its terms and provisions.

Expected Timing of the Merger

The merger is expected to be completed in the first quarter of 2018. However, neither SandRidge nor Bonanza Creek can predict the actual date on which the merger will be completed, nor can the parties assure that the merger will be completed, because completion is subject to conditions beyond each party’s control.

Comparison of Rights of Common Stockholders of SandRidge and Common Stockholders of Bonanza Creek

Bonanza Creek stockholders receiving shares of SandRidge common stock in connection with the merger will have different rights once they become stockholders of SandRidge due to differences between the governing corporate documents of SandRidge and Bonanza Creek. These differences are described in more detail under “Comparison of Rights of Common Stockholders of SandRidge and Common Stockholders of Bonanza Creek.”
