Item 7.01 Regulation FD

At a General Assembly Meeting held on December 17, 2018, the shareholders of ARO Drilling unanimously approved the capitalization of the shareholder commission (or interest) due in 2018 under each of the loan agreements to Mukamala Oil Field Services Limited, a wholly owned subsidiary of Saudi Aramco, and Rowan REX Limited, a wholly owned subsidiary of Rowan Companies plc, which was expected to be approximately $12 million each. The capitalization results in an increase in the principal amount due under each of the loans. Resumption of interest paid in cash will be determined by the ARO Drilling board and shareholders, as applicable, in future meetings. Other decisions recently agreed upon by the joint venture, include:
