SDLP - Seadrill Partners Announces One for Ten Reverse Unit Split

London, United Kingdom, May 30, 2019 - Seadrill Partners LLC (the "Company" or "SDLP") (NYSE: SDLP) announces a one-for-ten reverse unit split on its common units and subordinated units, which is expected to be effective after the close of trading on July 1, 2019. Trading of the split adjusted common units will commence the following day under the same ticker symbol "SDLP" on the New York Stock Exchange.

The reverse split will affect all common and subordinated unitholders uniformly and will not alter unit classes or ownership interests in the Company, except to the extent that the reverse split results in any of the Company's unitholders owning a fractional unit. No fractional units will be issued in connection with the reverse split. Instead, in accordance with the limited liability company agreement, all fractional SDLP units will be rounded to the nearest whole unit, with 0.5 units rounded to the next higher unit.

The reverse split will reduce the number of common units issued and outstanding from 75,278,250 to approximately 7,527,825 common units, and the subordinated units from 16,543,350 to approximately 1,654,335 subordinated units.

SDLP unitholders who own their units in book-entry form or through a bank, broker or other nominee do not need to take any action in connection with the reverse split.  Every ten SDLP common units (CUSIP #Y7545W 109) will be automatically converted into one new SDLP common unit (CUSIP #Y7545W 125).  Every ten subordinated units will be automatically converted into one new SDLP subordinated unit.

Unitholders who hold units with a broker, bank or other nominee and who have any questions in this regard are encouraged to contact their brokers, banks or other nominees.

Formal notice of the reverse split is being sent to unitholders of the Company. Electronic copies of the materials are accessible on the Company's website at:
