Cushing® Asset Management and Swank Capital Announce Constituent Changes to The Cushing® MLP High Income Index

DALLAS, Sept. 18, 2020 - Cushing^® Asset Management, LP, and Swank Capital, LLC, announce two upcoming interim changes to constituents of The Cushing^® MLP High Income Index (the "Index"), as follows:

On July 26, 2020, Index constituent CNX Midstream Partners LP (NYSE: CNXM) entered into an Agreement and Plan of Merger ("Merger Agreement") with CNX Resources Corp. (NYSE: CNX) and affiliated companies that would result in CNXM common units ceasing to be publicly traded, subject to the approval of the holders of CNXM common units and Class B units. Entities representing a majority of CNXM common units and Class B units have agreed to deliver written consents approving the Merger Agreement within the unitholder consent period, which may terminate as early as September 25, 2020. Per the Index's methodology guide, this event will result in a constituent replacement. Accordingly, after the market closes on September 25, 2020, and effective on September 28, 2020, Enviva Partners, LP (NYSE: EVA) will replace CNXM as a constituent of the Index at CNXM's then-current weight.

On July 13, 2020, Black Stone Minerals, L.P. (NYSE: BSM) was added as a constituent of the Index despite being ineligible for inclusion in the Index due to a distribution cut announcement made on February 5, 2020. After the market closes on September 25, 2020, and effective on September 28, 2020, Targa Resources Corp. (NYSE: TRGP) will replace BSM at BSM's then-current weight.

There will be no changes to the remaining constituents of the Index due to these events.
