DISCLOSURES REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q (“Quarterly Report”) includes “forward-looking statements” about the Trust, SandRidge and other matters discussed herein that are subject to risks and uncertainties within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). All statements other than statements of historical fact included in this document, including, without limitation, statements under “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Item 2 of Part I and elsewhere herein regarding the Trust’s or SandRidge’s plans and objectives for future operations, are forward-looking statements. Actual outcomes and results may differ materially from those projected. Forward-looking statements are generally accompanied by words such as “estimate,” “target,” “project,” “predict,” “believe,” “expect,” “anticipate,” “potential,” “could,” “may,” “foresee,” “plan,” “goal,” “should,” “intend” or other words that convey the uncertainty of future events or outcomes. We have based these forward-looking statements on our current expectations and assumptions about future events. These statements are based on certain assumptions made by us in light of our experience and our perception of historical trends, current conditions and expected future developments as well as other factors we believe are appropriate under the circumstances. However, whether actual results and developments will conform with our expectations and predictions is subject to a number of risks and uncertainties, including the risk factors discussed in Item 1A of the Trust’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015 (the “2015 Form 10-K”), which could affect the future results of the energy industry in general, and the Trust and SandRidge in particular, and could cause those results to differ materially from those expressed in such forward-looking statements.

1. Organization of Trust

SandRidge Mississippian Trust I (the “Trust”) is a statutory trust formed under the Delaware Statutory Trust Act pursuant to a trust agreement, as amended and restated, by and among SandRidge Energy, Inc. (“SandRidge”), as Trustor, The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Trustee”), and The Corporation Trust Company, as Delaware Trustee (the “Delaware Trustee”).

The Trust holds Royalty Interests in specified oil and natural gas properties located in the Mississippian formation in Alfalfa, Garfield, Grant and Woods counties in Oklahoma (the “Underlying Properties”). The Royalty Interests were conveyed by SandRidge to the Trust concurrent with the initial public offering of the Trust’s common units in April 2011. As consideration for conveyance of the Royalty Interests, the Trust remitted the proceeds of the offering, along with 3,750,000 Trust common units and 7,000,000 Trust subordinated units, to certain wholly owned subsidiaries of SandRidge. At June 30, 2016, SandRidge owned 7,528,063 Trust units, or approximately 26.9% of all Trust units.

The Trust is passive in nature and neither the Trust nor the Trustee has any control over, or responsibility for, any operating or capital costs related to the Underlying Properties. The business and affairs of the Trust are administered by the Trustee. The trust agreement generally limits the Trust’s business activities to owning the Royalty Interests and any activity reasonably related to such ownership, including activities required or permitted by the terms of the conveyances related to the Royalty Interests and a derivatives agreement between the Trust and SandRidge.

The Trust makes quarterly cash distributions of substantially all of its cash receipts, after deducting amounts for the Trust’s administrative expenses and cash reserves withheld by the Trustee, on or about the 60th day following the completion of each quarter. Due to the timing of the payment of production proceeds to the Trust, each distribution covers production from a three-month period consisting of the first two months of the most recently ended quarter and the final month of the quarter preceding it.

The Trust will dissolve and begin to liquidate on December 31, 2030 (the “Termination Date”) and will soon thereafter wind up its affairs and terminate. At the Termination Date, 50% of the Royalty Interests will revert automatically to SandRidge. The remaining 50% of the Royalty Interests will be sold at that time, with the net proceeds of the sale, as well as any remaining Trust cash reserves, distributed to the unitholders on a pro rata basis. SandRidge has a right of first refusal to purchase the Royalty Interests retained by the Trust at the Termination Date. The Trust will not dissolve until the Termination Date unless any of the following occurs: (a) the Trust sells all of the Royalty Interests; (b) cash available for distribution is less than $1.0 million for any four consecutive quarters; (c) Trust unitholders approve an earlier dissolution of the Trust; or (d) the Trust is judicially dissolved. In the case of any of the foregoing, the Trustee would then sell all of the Trust’s assets, either by private sale or public auction, and distribute the net proceeds of the sale to the Trust unitholders after payment, or reasonable provision for payment, of all Trust liabilities.

2. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Accounting. The financial statements of the Trust differ from financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) as the Trust records revenues when cash is received (rather than when earned) and expenses when paid (rather than when incurred) and may also establish cash reserves for contingencies, which would not be accrued in financial statements prepared in accordance with GAAP. This comprehensive basis of accounting other than GAAP corresponds to the accounting permitted for royalty trusts by the Securities and Exchange Commission (“SEC”) as specified by Staff Accounting Bulletin Topic 12:E, Financial Statements of Royalty Trusts. Amortization of investment in royalty interests, calculated on a unit-of-production basis, and any impairments are charged directly to trust corpus. Distributions to unitholders are recorded when declared.

Significant Accounting Policies. Most accounting pronouncements apply to entities whose financial statements are prepared in accordance with GAAP, which may require such entities to accrue or defer revenues and expenses in a period other than when such revenues are received or expenses are paid. Because the Trust’s financial statements are prepared on the modified cash basis as described above, most accounting pronouncements are not applicable to the Trust’s financial statements.

The Trust is treated for federal and applicable state income tax purposes as a partnership. For U.S. federal income tax purposes, a partnership is not a taxable entity and incurs no U.S. federal income tax liability. With respect to state taxation, a partnership is typically treated in the same manner as it is for U.S. federal income tax purposes.

Impairment of Investment in Royalty Interests.  On a quarterly basis, the Trust evaluates the carrying value of the Investment in Royalty Interests by comparing the undiscounted cash flows expected to be realized from the Royalty Interest to the carrying value. If the expected future undiscounted cash flows are less than the carrying value, the Trust recognizes an impairment loss for the difference between the carrying value and the estimated fair value of the Royalty Interest.  There were no impairments in the carrying value of the Investment in Royalty Interests during the six-month periods ended June 30, 2016 and 2015. Material write-downs in subsequent periods may occur if commodity prices decline. Any impairment would result in a non-cash charge to trust corpus and would not affect the Trust’s distributable income. See “Risks and Uncertainties” in Note 5 below for further discussion.

Distributable Income Per Common Unit. Distributable income per unit amounts as calculated for the periods presented in the accompanying unaudited statements of distributable income may differ from declared distribution amounts per unit due to rounding.

Interim Financial Statements. The accompanying unaudited interim financial statements have been prepared in accordance with the accounting policies stated in the audited financial statements contained in the 2015 Form 10-K and reflect all adjustments that are, in the opinion of the Trustee, necessary to state fairly the information in the Trust’s unaudited interim financial statements. The accompanying statement of assets and trust corpus as of December 31, 2015 has been derived from audited financial statements. The unaudited interim financial statements should be read in conjunction with the audited financial statements and notes thereto included in the 2015 Form 10-K.

3. Distributions to Unitholders

The Trust makes quarterly cash distributions of substantially all of its cash receipts, after deducting amounts for the Trust’s administrative expenses and cash reserves withheld by the Trustee, on or about the 60th day following the completion of each quarter. Distributions cover a three-month production period. See Note 6 for discussion of the Trust’s quarterly distribution to be paid in August 2016. A summary of the Trust’s distributions to unitholders during the six-month period ended June 30, 2016 and the year ended December 31, 2015 is as follows:

4. Related Party Transactions

Trustee Administrative Fee. Under the terms of the trust agreement, the Trust pays an annual administrative fee of $150,000 to the Trustee, which will be adjusted for inflation by no more than 3% in any year beginning in 2017. The Trustee’s administrative fees paid during each of the three-month periods ended June 30, 2016 and 2015 totaled approximately $38,000. The Trustee’s administrative fees paid during each of the six-month periods ended June 30, 2016 and 2015 totaled approximately $75,000.

Registration Rights Agreement. The Trust is party to a registration rights agreement pursuant to which the Trust has agreed to register the offering of the Trust units held by SandRidge and certain of its affiliates and permitted transferees upon request by

(Unaudited)

SandRidge. The holders have the right to require the Trust to file no more than five registration statements in aggregate, one of which has been filed to date. The Trust does not bear any expenses associated with such transactions.

Administrative Services Agreement. The Trust is party to an administrative services agreement with SandRidge that obligates the Trust to pay SandRidge an annual administrative services fee for accounting, tax preparation, bookkeeping and informational services performed by SandRidge on behalf of the Trust. For its services under the administrative services agreement, SandRidge receives an annual fee of $200,000, which is payable in equal quarterly installments and will remain fixed for the life of the Trust. SandRidge is also entitled to receive reimbursement for its out-of-pocket fees, costs and expenses incurred in connection with the provision of any of the services under this agreement. The administrative services agreement will terminate on the earliest to occur of: (i) the date the Trust shall have dissolved and commenced winding up in accordance with the trust agreement, (ii) the date that all of the Royalty Interests have been terminated or are no longer held by the Trust, (iii) pertaining to services to be provided with respect to any Underlying Properties transferred by SandRidge, the date that either SandRidge or the Trustee may designate by delivering 90-days’ prior written notice, provided that the transferee of such Underlying Properties assumes responsibility to perform the services in place of SandRidge and (iv) a date mutually agreed to by SandRidge and the Trustee. During each of the three-month periods ended June 30, 2016 and 2015, the Trust paid administrative fees to SandRidge equal to $50,000. Administrative fees paid to SandRidge for the six-month periods ended June 30, 2016 and 2015 totaled $50,000 and $150,000, respectively.

Derivatives Agreement. The Trust and SandRidge were parties to a derivatives agreement that provided the Trust with the economic effect of certain oil and natural gas derivative contracts entered into by SandRidge with third parties for production through December 31, 2015. Under the derivatives agreement, SandRidge paid the Trust amounts it received from its counterparties and the Trust paid SandRidge any amounts that SandRidge was required to pay such counterparties. The Trust did not bear any costs related to the establishment of the underlying contracts. The Trust does not have the ability to enter into its own derivative contracts. The commodity derivative contracts underlying the derivatives agreement consisted of fixed price swaps and collars.

5. Commitments and Contingencies

Loan Commitment. Pursuant to the trust agreement, if at any time the Trust’s cash on hand (including available cash reserves) is not sufficient to pay the Trust’s ordinary course administrative expenses as they become due, SandRidge will, at the Trustee’s request, loan funds to the Trust necessary to pay such expenses; provided, however, that this obligation is unlikely to be fulfilled during the pendency of SandRidge’s bankruptcy. Any funds loaned by SandRidge pursuant to this commitment will be limited to the payment of current accounts payable or other obligations to trade creditors in connection with obtaining goods or services or the payment of other current liabilities arising in the ordinary course of the Trust’s business, and may not be used to satisfy Trust indebtedness, or to make distributions. If SandRidge loans funds pursuant to this commitment, no further distributions will be made to unitholders (except in respect of any previously determined quarterly cash distribution amount) until such loan is repaid. Any such loan will be on an unsecured basis, and the terms of such loan will be substantially the same as those which would be obtained in an arm’s length transaction between SandRidge and an unaffiliated third party. There was no such loan outstanding with SandRidge at June 30, 2016 or December 31, 2015.

Risks and Uncertainties. The Trust’s revenue and distributions are substantially dependent upon the prevailing and future prices for oil and natural gas, each of which depends on numerous factors beyond the Trust’s control such as overall oil and natural gas production and inventories in relevant markets, economic conditions, the global political environment, regulatory developments and competition from other energy sources. Oil and natural gas prices historically have been volatile and may be subject to significant fluctuations in the future. The Trust’s derivative arrangements served to mitigate a portion of the effect of this price volatility through December 31, 2015. Low levels of future production, continued low commodity prices and the absence of any derivative arrangements would continue to reduce the Trust’s revenues and distributable income available to unitholders.

The Trust is highly dependent on its Trustor, SandRidge, for multiple services, including the operation of the Trust wells, remittance of net proceeds from the sale of associated production to the Trust, administrative services such as accounting, tax preparation, bookkeeping and informational services performed on behalf of the Trust. The ability to operate the properties depends on the Trustor’s future financial condition and economic performance, access to capital, and other factors, many of which are out of the control of the Trustor. On May 16, 2016, the Trustor and certain of its direct and indirect subsidiaries (collectively, the “Debtors”) filed voluntary petitions for reorganization under Chapter 11 of the United States Bankruptcy Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the Southern District of Texas (the “Bankruptcy Court”). The cases are jointly administered under the caption In re: SandRidge Energy Inc., et al. The Debtors continue to operate the business as “debtors-in-possession” under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court.

Legal Proceedings. On May 11, 2015, the U.S. District Court for the Western District of Oklahoma issued an order dismissing all claims against the Trust in a putative class action lawsuit filed by unitholders of the Trust and stockholders of SandRidge, in which the plaintiffs asserted a variety of federal securities claims against the Trust, SandRidge and certain of SandRidge’s current and former officers and directors, among other defendants.  As a result of the order, the Trust is no longer a party in the lawsuit.  However, the dismissal was based on a procedural defect, and thus was made without prejudice to the plaintiffs’ rights, if any, to refile their claims against the Trust once the defect is cured.

On June 9, 2015, the Duane & Virginia Lanier Trust, on behalf of itself and all other similarly situated unitholders of the Trust, filed a putative class action complaint in the U.S. District Court for the Western District of Oklahoma against the Trust, SandRidge and certain current and former executive officers of SandRidge, among other defendants (the “Securities Litigation”). The complaint asserts a variety of federal securities claims on behalf of a putative class of (a) purchasers of common units of the Trust in or traceable to its initial public offering on or about April 7, 2011, and (b) purchasers of common units of SandRidge Mississippian Trust II in or traceable to its initial public offering on or about April 17, 2012.  The claims are based on allegations that SandRidge and certain of its current and former officers and directors, among other defendants, including the Trust, are responsible for making false and misleading statements, and omitting material information, concerning a variety of subjects, including oil and gas reserves. The plaintiffs seek class certification, an order rescinding the Trust’s initial public offering and an unspecified amount of damages, plus interest, attorneys’ fees and costs. On May 20, 2016, the Court entered an Administrative Closing Order terminating the action, without prejudice to the rights of the parties to reopen the proceeding for good cause shown, within thirty days after the termination of SandRidge’s bankruptcy proceedings.

Regardless of the outcome of the litigation, the Trust may incur expenses in defending the litigation, and any such expenses may increase the Trust’s administrative expenses significantly. The Trust will estimate and financially provide for potential losses that may arise out of litigation to the extent that such losses are probable and can be reasonably estimated. Significant judgment will be required in making any such estimates and any final liabilities of the Trust may ultimately be materially different than any estimates. The Trust is currently unable to assess the probability of loss or estimate a range of any potential loss the Trust may incur in connection with the Securities Litigation, and has not established any reserves relating to the Securities Litigation. The Trust may withhold estimated amounts from future distributions to cover future costs associated with the litigation if determined necessary. The Trust has not yet fully analyzed any rights it may have to indemnities that may be applicable or any claims it may make in connection with the Securities Litigation.

6. Subsequent Events

Distribution to Unitholders. On July 28, 2016, the Trust declared a cash distribution of $0.0412 per unit covering production for the three-month period from March 1, 2016 to May 31, 2016. The distribution will be paid on or about August 26, 2016 to record holders as of August 12, 2016. Distributable income for March 1, 2016 to May 31, 2016 was calculated as follows (in thousands, except for unit and per unit amounts):

ITEM 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Introduction

The following discussion and analysis is intended to help the reader understand the financial condition, results of operations, liquidity and capital resources of SandRidge Mississippian Trust I (the “Trust”). This discussion and analysis should be read in conjunction with the Trust’s unaudited interim financial statements and the accompanying notes included in this Quarterly Report and the Trust’s audited financial statements and the accompanying notes included in the 2015 Form 10-K.

Overview

The Trust is a statutory trust created under the Delaware Statutory Trust Act. The business and affairs of the Trust are administered by the Trustee and, as necessary, the Delaware Trustee. The Trust’s purpose is to hold the Royalty Interests, to distribute to the Trust unitholders cash that the Trust receives in respect of the Royalty Interests and the derivatives agreement (described in Note 4 to the unaudited interim financial statements contained in Part I, Item 1 of this Quarterly Report) and to perform certain administrative functions in respect of the Royalty Interests and the Trust units. Other than the foregoing activities, the Trust does not conduct any operations or activities. The Trustee has no involvement with, control or authority over, or responsibility for, any aspect of the operations on or relating to the properties in which the Trust has an interest. The Trust derives all or substantially all of its income and cash flow from the Royalty Interests and, during its term, the derivatives agreement. The Trust is treated as a partnership for federal income tax purposes.

Commodity Price Volatility. The Trust’s quarterly cash distributions are highly dependent upon the prices realized from the sale of oil, natural gas and natural gas liquids (“NGL”). The markets for these commodities are volatile and experienced significant pricing declines beginning in the latter half of 2014. Although distributions relating to production through December 31, 2015 were partially supported by hedging arrangements, no such arrangements are in place for production attributable to periods thereafter, and consequently distributions for production periods beginning January 1, 2016 or later should be expected to be lower than distributions for recent periods. The Trust received net settlement proceeds of approximately $2.7 million and $6.0 million during the three-month periods ended June 30, 2016 and 2015, respectively. The Trust received net settlement proceeds of approximately $9.6 million and $8.3 million during the six-month periods ended June 30, 2016 and 2015, respectively.

Properties. As of June 30, 2016, the Trust’s properties consisted of Royalty Interests in oil and natural gas wells located in Alfalfa, Garfield, Grant and Woods counties in Oklahoma.

Distributions. The Trust makes quarterly cash distributions of substantially all of its cash receipts, after deducting amounts for the Trust’s administrative expenses and cash reserves withheld by the Trustee, on or about the 60th day following the completion of each quarter.

Pursuant to Internal Revenue Code (“IRC”) Section 1446, withholding tax on income effectively connected to a United States trade or business allocated to foreign partners should be made at the highest marginal rate. Under IRC Section 1441, withholding tax on fixed, determinable, annual, periodic income from United States sources allocated to foreign partners should be made at 30% of gross income unless the rate is reduced by treaty. This is intended to be a qualified notice to nominees and brokers as provided for under Treasury Regulation Section 1.1446-4(b) by the Trust, and while specific relief is not specified for IRC Section 1441 income, this disclosure is intended to suffice. Nominees and brokers should withhold at the highest marginal rate, currently 39.6% for individuals, on the distribution made to foreign partners.

Litigation. As described in more detail in Item 1 of Part II, Legal Proceedings, claims brought against the Trust in a putative class action against SandRidge and others were dismissed in the second quarter of 2015. However, the dismissal was based on a procedural defect, and thus was made without prejudice to the plaintiffs’ rights, if any, to refile their claims against the Trust once the defect is cured. Regardless of the outcome of the litigation, the Trust may incur expenses in defending the litigation, and any such expenses may increase the Trust’s administrative expenses significantly. Further, any costs incurred by the Trust in connection with any settlement of or judgment in the litigation could increase the Trust’s administrative expenses significantly.

Results of Trust Operations

The primary factors affecting the Trust’s revenues and costs are the quantity of oil, natural gas and NGL production attributable to the Royalty Interests, the prices received for such production and amounts paid or received as net settlements under the derivatives agreement during its term. Royalty income, post-production expenses, certain taxes and derivative settlements are recorded on a cash basis when net revenue distributions are received by the Trust from SandRidge. Information regarding the Trust’s production, pricing and costs for the three- and six-month periods ended June 30, 2016 and 2015 is presented below.

Table of Contents

Three Months Ended June 30, 2016 Compared to the Three Months Ended June 30, 2015

Revenues

Royalty Income. Royalty income received during the three-month period ended June 30, 2016 totaled $1.9 million compared to $4.1 million received during the three-month period ended June 30, 2015. Royalty income is a function of production volumes sold attributable to the Royalty Interests and associated prices received. Approximately $1.0 million of the total decrease in royalty income was attributable to the decrease in total volumes produced, caused by a reduction in the average number of producing wells and natural declines in production, and approximately $1.2 million was attributable to a decrease in prices received. The average number of producing wells decreased by 10 during the three-month period ended June 30, 2016 compared to the three-month period ended June 30, 2015 because wells that could not economically produce due to continued depressed pricing were shut-in. Royalty income received during the three-month period ended June 30, 2016 was based upon production attributable to the Royalty Interests of 26 MBbls of oil, 28 MBbls of NGL and 479 MMcf of natural gas, or 133 MBoe of combined production, for the period from December 1, 2015 to February 29, 2016.  Royalty income received during the three-month period ended June 30, 2015 was based upon production attributable to the Royalty Interests of 37 MBbls of oil, 33 MBbls of NGL and 602 MMcf of natural gas, or 170 MBoe of combined production, for the period from December 1, 2014 to February 28, 2015.  The average price received for oil decreased to $28.90 per Bbl during the three-month period ended June 30, 2016 from $48.89 per Bbl during the same period in 2015, while the average price received for NGL decreased to $9.96 per Bbl during the three-month period ended June 30, 2016 from $15.02 per Bbl during the same period in 2015. The average price received for natural gas decreased to $1.84 per Mcf during the three-month period ended June 30, 2016 from $2.93 per Mcf during the same period in 2015.

Derivative Settlements. The Trust’s derivatives agreement with SandRidge reduced the Trust’s exposure to commodity price volatility attributable to a portion of production from the Royalty Interests through December 31, 2015 by the use of oil fixed price swaps and natural gas collars. Net cash settlements under the derivatives agreement for the three-month period ended June 30, 2016 for production from December 1, 2015 to December 31, 2015 were approximately $2.7 million. This effectively increased the average price received for oil by $98.49 per Bbl to $127.39 per Bbl which was attributable primarily to the ratio of the oil volumes hedged to the oil volumes produced and the substantial declines in the market prices of oil. The average price received for natural gas increased by $0.32 per Mcf to $2.16 per Mcf ($1.64 per Mcf including the impact of post-production expenses). Net cash settlements under the derivatives agreement for the three-month period ended June 30, 2015 for production from December 1, 2014 to February 28, 2015 were approximately $6.0 million. This effectively increased the average price received for oil by $158.39 per Bbl to $207.28 per Bbl which was attributable primarily to the ratio of the oil volumes hedged to the oil volumes produced and the substantial declines in the market prices of oil. The average price received for natural gas increased by $0.27 per Mcf to $3.20 per Mcf ($2.70 per Mcf including the impact of post-production expenses). Net cash settlements received during both periods were comprised of gains on oil fixed price swaps and natural gas collars due to lower average commodity prices at the time of settlement compared to contract prices.

Expenses

Post-Production Expenses. The Trust bears post-production expenses attributable to production from the Royalty Interests. Post-production expenses generally consist of costs incurred to gather, store, compress, transport, process, treat, dehydrate and market natural gas produced. Post-production expenses for the three-month period ended June 30, 2016 totaled approximately $0.2 million compared to approximately $0.3 million for the three-month period ended June 30, 2015. Post-production costs decreased as a result of decreased natural gas production.

Production Taxes. Production taxes are calculated as a percentage of oil and natural gas revenues, excluding the effects of derivative settlements and net of any applicable tax credits. Production taxes for the three-month period ended June 30, 2016 totaled approximately $0.1 million, or $0.55 per Boe, and were approximately 3.8% of royalty income. Production taxes for the three-month period ended June 30, 2015 totaled approximately $0.1 million, or $0.80 per Boe, and were approximately 3.4% of royalty income. Production tax rates increased due to Trust wells reaching the expiration point of a previously reduced tax rate. The average effective production tax rate for the Trust will continue to increase as more Trust wells reach this expiration point.

Trust Administrative Expenses. Trust administrative expenses generally consist of fees paid to the Trustee and the Delaware Trustee, administrative services fees paid to SandRidge, tax return and related form preparation fees, legal and accounting fees, and other expenses incurred as a result of being a publicly traded entity. Trust administrative expenses for the three-month period ended June 30, 2016 totaled approximately $0.3 million compared to approximately $0.4 million for the three-month period ended June 30, 2015.

Distributable Income

Distributable income for the three-month period ended June 30, 2016 was $3.9 million, which included a net addition to the cash reserve for payment of future Trust expenses of approximately $78,000 (approximately $386,000 withheld from the May 2016 cash distribution to unitholders partially offset by approximately $308,000 used to pay Trust expenses during the period). Distributable income for the three-month period ended June 30, 2015 was $9.3 million, which included a net reduction to the cash reserve for payment of future Trust expenses of approximately $53,000 (approximately $439,000 used to pay Trust expenses during the period partially offset by approximately $386,000 withheld from the May 2015 cash distribution to unitholders).

Six Months Ended June 30, 2016 Compared to the Six Months Ended June 30, 2015

Revenues

Royalty Income. Royalty income received during the six-month period ended June 30, 2016 totaled $4.4 million compared to $11.2 million received during the six-month period ended June 30, 2015. Approximately $3.3 million of the total decrease in royalty income was attributable to the decrease in total volumes produced, caused by a reduction in the average number of producing wells and natural declines in production, and approximately $3.5 million was attributable to a decrease in prices received. The average number of producing wells decreased by 13 during the six-month period ended June 30, 2016 compared to the six-month period ended June 30, 2015 because wells that could not economically produce due to continued depressed pricing were shut-in. Royalty income received during the six-month period ended June 30, 2016 was based upon production attributable to the Royalty Interests of 52 MBbls of oil, 55 MBbls of NGL and 995 MMcf of natural gas, or 273 MBoe of combined production, for the period from September 1, 2015 to February 29, 2016. Royalty income received during the six-month period ended June 30, 2015 was based upon production attributable to the Royalty Interests of 83 MBbls of oil, 68 MBbls of NGL and 1,299 MMcf of natural gas, or 367 MBoe of combined production, for the period from September 1, 2014 to February 28, 2015.  The average price received for oil decreased to $35.67 per Bbl during the six-month period ended June 30, 2016 from $67.14  per Bbl during the same period in 2015, while the average price received for NGL decreased to $11.62 per Bbl during the six-month period ended June 30, 2016 from $22.73 per Bbl during the same period in 2015. The average price received for natural gas decreased to $1.92 per Mcf during the six-month period ended June 30, 2016 from $3.18 per Mcf during the same period in 2015.

Derivative Settlements. Net cash settlements under the derivatives agreement for the six-month period ended June 30, 2016 for production from September 1, 2015 to December 31, 2015 were approximately $9.6 million. This effectively increased the average price received for oil by $175.67 per Bbl to $211.34 per Bbl which was attributable primarily to the ratio of the oil volumes hedged to the oil volumes produced and the substantial declines in the market prices of oil. The average price received for natural gas increased by $0.55 per Mcf to $2.47 per Mcf ($1.96 per Mcf including the impact of post-production expenses). Net cash settlements under the derivatives agreement for the six-month period ended June 30, 2015 for production from September 1, 2014 to February 28, 2015 were approximately $8.3 million. This effectively increased the average price received for oil by $97.99 per Bbl to $165.13 per Bbl which was attributable primarily to the ratio of the oil volumes hedged to the oil volumes produced and the substantial declines in the market prices of oil. The average price received for natural gas increased by $0.16 per Mcf to $3.34 per Mcf ($2.86 per Mcf including the impact of post-production expenses). Net cash settlements received during both periods were comprised of gains on oil fixed price swaps and natural gas collars due to lower average commodity prices at the time of settlement compared to contract prices.

Expenses

Post-Production Expenses. Post-production expenses for the six-month period ended June 30, 2016 totaled approximately $0.5 million compared to approximately $0.6 million for the six-month period ended June 30, 2015. Post-production costs decreased as a result of decreased natural gas production.

Production Taxes. Production taxes for the six-month period ended June 30, 2016 totaled approximately $0.2 million, or $0.59 per Boe, and were approximately 3.6% of royalty income. Production taxes for the six-month period ended June 30, 2015 totaled approximately $0.3 million, or $0.90 per Boe, and were approximately 2.9% of royalty income. Production tax rates increased due to Trust wells reaching the expiration point of a previously reduced tax rate.

Trust Administrative Expenses. Trust administrative expenses for the six-month period ended June 30, 2016 totaled approximately $0.9 million compared to approximately $1.1 million for the six-month period ended June 30, 2015.

Distributable Income

Distributable income for the six-month period ended June 30, 2016 was $12.6 million, which included a net reduction to the cash reserve for payment of future Trust expenses of approximately $175,000  (approximately $947,000 used to pay Trust expenses during the period partially offset by approximately $772,000  withheld from the February 2016 and May 2016 cash distributions to unitholders). Distributable income for the six-month period ended June 30, 2015 was $17.8 million, which included a net reduction to the cash reserve for payment of future Trust expenses of approximately $0.3 million (approximately $1.1 million used to pay Trust expenses during the period partially offset by approximately $0.8 million withheld from the February 2015 and May 2015 cash distributions to unitholders).

Liquidity and Capital Resources

The Trust’s principal sources of liquidity and capital are cash flow generated from the Royalty Interests and, during the term of the derivatives agreement, the Trust’s derivative contracts, and borrowings to fund administrative expenses, including any amounts borrowed under SandRidge’s loan commitment described in Note 5 to the unaudited interim financial statements contained in Part I, Item 1 of this Quarterly Report. The Trust’s primary uses of cash are distributions to Trust unitholders, including, if applicable, payment of amounts owed under the Trust’s derivative contracts during the term of the derivatives agreement, payment of Trust administrative expenses, including any reserves established by the Trustee for future liabilities, payment of applicable taxes and payment of expense reimbursements to SandRidge for out-of-pocket expenses incurred on behalf of the Trust. Under the conveyances granting the Royalty Interests, the Trust does not have any operating or capital cost requirements related to the wells.

Administrative expenses include payments to the Trustee and the Delaware Trustee as well as a quarterly fee of $50,000 to SandRidge pursuant to an administrative services agreement. Each quarter, the Trustee determines the amount of funds available for distribution. Available funds are the excess cash, if any, received by the Trust from the sale of production attributable to the Royalty Interests that quarter over the Trust’s expenses for the quarter. If at any time the Trust’s cash on hand (including available cash reserves) is not sufficient to pay the Trust’s ordinary course administrative expenses as they become due, the Trust may borrow funds from the Trustee or other lenders, including SandRidge, to pay such expenses. The Trustee does not intend to lend funds to the Trust. If such funds are borrowed, no further distributions will be made to unitholders (except in respect of any previously determined quarterly distribution amount) until the borrowed funds have been repaid. There was no such loan outstanding at June 30, 2016 or December 31, 2015.

The Trust is highly dependent on its Trustor, SandRidge, for multiple services, including the operation of the Trust wells, remittance of net proceeds from the sale of associated production to the Trust, administrative services such as accounting, tax preparation, bookkeeping and informational services performed on behalf of the Trust. The ability to operate the properties depends on the Trustor’s future financial condition and economic performance, access to capital, and other factors, many of which are out of the control of the Trustor. On May 16, 2016, the Trustor and certain of its direct and indirect subsidiaries (collectively, the “Debtors”) filed voluntary petitions  for reorganization under Chapter 11 of the United States Bankruptcy Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the Southern District of Texas (the “Bankruptcy Court”). The cases are jointly administered under the caption In re: SandRidge Energy Inc., et al.  The Debtors continue to operate the business as “debtors-in-possession” under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court.

2016 Trust Distributions to Unitholders. During the six-month period ended June 30, 2016, the Trust’s distributions to unitholders were as follows:

Future Trust Distributions to Unitholders. During the three-month production period from March 1, 2016 to May 31, 2016, total sales volumes were slightly lower than the previous period. The decrease in revenue compared to the previous period was partially due to the expiration of the derivatives agreement that had provided the Trust with the economic effect of certain oil and natural gas derivative contracts entered into by SandRidge with third parties for production through December 31, 2015. On July 28, 2016, the Trust declared a cash distribution of $0.0412 per unit covering production for the period. The distribution will be paid on or

about August 26, 2016 to record unitholders as of August 12, 2016 and was calculated as follows (in thousands, except for unit and per unit amounts):

(1)                  Includes amounts withheld for payment of future Trust administrative expenses.

As the Trust cannot acquire or cause additional wells to be drilled on its behalf, the Trust’s production is expected to decline each quarter during the remainder of its life.

ITEM 3. Quantitative and Qualitative Disclosures about Market Risk

Commodity Price Risk. Because the Trust’s primary asset and source of income is the Royalty Interests, which generally entitle the Trust to receive a portion of the net proceeds from sales of production from the Underlying Properties, the Trust’s most significant market risk relates to the prices received for oil, natural gas and NGL production. Revenue derived from the Royalty Interests, and therefore the amount of cash flow available for distribution to the Trust unitholders, depends substantially on prevailing oil, natural gas and NGL prices. Lower prices may also reduce the amount of oil, natural gas and NGL that can be economically produced from the Underlying Properties.

The Trust was party to a derivatives agreement with SandRidge that provided the Trust with the economic effect of certain oil and natural gas derivative contracts for production through December 31, 2015 (which had effects extending into the May 2016 distribution to unitholders) and mitigated a portion of the variability of oil and natural gas prices received for the Trust’s share of production. The Trust received net settlement proceeds of approximately $9.6 million and $8.3 million related to the derivatives agreement during the six-month periods ended June 30, 2016 and 2015, respectively. The Trust no longer has the benefit of the derivative contracts, and therefore the amount of future cash distributions will be subject to unmitigated changes in oil and natural gas prices. The Trust does not have the ability to enter into additional derivative contracts.

ITEM 4. Controls and Procedures

Disclosure Controls and Procedures

The Trustee conducted an evaluation of the Trust’s disclosure controls and procedures, as defined in Rules 13a-15 and 15d-15 under the Exchange Act, designed to ensure that information required to be disclosed by the Trust in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and such information is accumulated and communicated as appropriate to allow timely decisions regarding required disclosure. Based on this evaluation, the Trustee has concluded that the disclosure controls and procedures of the Trust are effective as of the end of the period covered by this report. In its evaluation of disclosure controls and procedures, the Trustee has relied, to the extent considered reasonable, on information provided by SandRidge.

Due to the nature of the Trust as a passive entity and in light of the contractual arrangements pursuant to which the Trust was created, including the provisions of (i) the trust agreement, (ii) the administrative services agreement, (iii) the development agreement and (iv) the conveyances granting the Royalty Interests, the Trustee’s disclosure controls and procedures related to the Trust necessarily rely on (A) information provided by SandRidge, including information relating to results of operations, the costs and revenues attributable to the Trust’s interests under the conveyance and other operating and historical data, plans for future operating and capital expenditures, reserve information, information relating to projected production, and other information relating to the status and results of operations of the Underlying Properties and the Royalty Interests, and (B) conclusions and reports regarding reserves by the Trust’s independent reserve engineers.

Changes in Internal Control Over Financial Reporting

There were no changes in the Trust’s internal control over financial reporting during the quarter ended June 30, 2016, that have materially affected, or are reasonably likely to materially affect, the Trustee’s internal control over financial reporting. The Trustee notes for purposes of clarification that it has no authority over, has not evaluated and makes no statement concerning, the internal control over financial reporting of SandRidge.

PART II. Other Information

ITEM 1. Legal Proceedings

On May 11, 2015, the U.S. District Court for the Western District of Oklahoma issued an order dismissing all claims against the Trust in a putative class action lawsuit filed by unitholders of the Trust and stockholders of SandRidge, in which the plaintiffs asserted a variety of federal securities claims against the Trust, SandRidge and certain of SandRidge’s current and former officers and directors, among other defendants.  As a result of the order, the Trust is no longer a party in the lawsuit.  However, the dismissal was based on a procedural defect, and thus was made without prejudice to the plaintiffs’ rights, if any, to refile their claims against the Trust once the defect is cured.

On June 9, 2015, the Duane & Virginia Lanier Trust, on behalf of itself and all other similarly situated unitholders of the Trust, filed a putative class action complaint in the U.S. District Court for the Western District of Oklahoma against the Trust, SandRidge and certain current and former executive officers of SandRidge, among other defendants (the “Securities Litigation”). The complaint asserts a variety of federal securities claims on behalf of a putative class of (a) purchasers of common units of the Trust in or traceable to its initial public offering on or about April 7, 2011, and (b) purchasers of common units of SandRidge Mississippian Trust II in or traceable to its initial public offering on or about April 17, 2012.  The claims are based on allegations that SandRidge and certain of its current and former officers and directors, among other defendants, including the Trust are responsible for making false and misleading statements, and omitting material information, concerning a variety of subjects, including oil and gas reserves. The plaintiffs seek class certification, an order rescinding the Trust’s initial public offering and an unspecified amount of damages, plus interest, attorneys’ fees and costs. On May 20, 2016, the Court entered an Administrative Closing Order terminating the action, without prejudice to the rights of the parties to reopen the proceeding for good cause shown, within thirty days after the termination of SandRidge’s bankruptcy proceedings.

Regardless of the outcome of the litigation, the Trust may incur expenses in defending the litigation, and any such expenses may increase the Trust’s administrative expenses significantly. The Trust will estimate and financially provide for potential losses that may arise out of litigation to the extent that such losses are probable and can be reasonably estimated. Significant judgment will be required in making any such estimates and any final liabilities of the Trust may ultimately be materially different than any estimates. The Trust is currently unable to assess the probability of loss or estimate a range of any potential loss the Trust may incur in connection with the Securities Litigation, and has not established any reserves relating to the Securities Litigation.  The Trust may withhold estimated amounts from future distributions to cover future costs associated with the litigation if determined necessary. The Trust has not yet fully analyzed any rights it may have to indemnities that may be applicable or any claims it may make in connection with the Securities Litigation.

ITEM 1A. Risk Factors

Risk factors relating to the Trust are contained in Item 1A of the 2015 Form 10-K. No material change to such risk factors has occurred during the three-month period ended June 30, 2016.
