SANDRIDGE MISSISSIPPIAN TRUST II

The Bank of New York Mellon Trust Company, N.A., Trustee

News Release

For Immediate Release

AUSTIN, Texas April 27, 2017 — SANDRIDGE MISSISSIPPIAN TRUST II (NYSE: SDR) today announced a quarterly distribution for the three-month period ended March 31, 2017 (which primarily relates to production attributable to the Trust’s interests from December 1, 2016 to February 28, 2017) of $3.4 million, or $0.069 per unit. The Trust makes distributions on a quarterly basis on or about the 60th day following the completion of each quarter. The distribution is expected to occur on or before May 26, 2017 to holders of record as of the close of business on May 12, 2017.

During the three-month production period ended February 28, 2017, combined sales volumes were slightly lower than the previous period; however, oil, natural gas and natural gas liquids (“NGL”) prices increased. As no additional development wells will be drilled, the Trust’s production is expected to decline each quarter during the remainder of its life.

The Trust owns royalty interests in oil and natural gas properties in the Mississippian formation in Alfalfa, Grant, Kay, Noble and Woods counties in northern Oklahoma and Barber, Comanche, Harper and Sumner counties in southern Kansas and is entitled to receive proceeds from the sale of production attributable to the royalty interests. As described in the Trust’s filings with the Securities and Exchange Commission (the “SEC”), the amount of the quarterly distributions is expected to fluctuate from quarter to quarter, depending on the proceeds received by the Trust as a result of actual production volumes, oil, natural gas and NGL prices and the amount and timing of the Trust’s administrative expenses, among other factors. All Trust unitholders share distributions on a pro rata basis.

Volumes, price and distributable income available to unitholders for the period were (dollars in thousands, except per unit):

Pursuant to 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 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 by SandRidge Mississippian Trust II to nominees and brokers as provided for under Treasury Regulation Section 1.1446-4(b), and while specific relief is not specified for Section 1441 income, this disclosure is intended to suffice.
