NEWPARK RESOURCES ANNOUNCES DEFINITIVE AGREEMENT TO SELL ITS U.S. MINERAL GRINDING BUSINESS

THE WOODLANDS, TX – October 20, 2022 – Newpark Resources, Inc. (NYSE: NR) (“Newpark” or the “Company”) today announced that it has entered into a definitive agreement to sell substantially all the long-lived assets, inventory and operations of its Excalibar mineral grinding business (“Excalibar”) to Cimbar Resources, INC. (“Cimbar”), a mineral-based additive solutions company based in Chatsworth, GA.

As of September 30, 2022, Excalibar had approximately $65 million of net capital employed. Under the terms of the agreement, Newpark expects to generate net cash of approximately $66 million through a combination of net cash proceeds at closing and net collections of certain retained assets and liabilities, including accounts receivable and accounts payable. In connection with the sale transaction, Cimbar and Newpark have also agreed to enter into a long-term barite supply agreement for Newpark’s U.S. drilling fluids business, with an initial term of four years following the closing of the transaction.

Matthew Lanigan, Newpark’s President and Chief Executive Officer, stated, “The sale of Excalibar is consistent with our stated strategy of transforming our Fluids Systems business into a more focused and capital-light business. We appreciate our dedicated Excalibar employees and thank them for their many years of valuable service to Newpark. We look forward to continuing to work with them and Cimbar under the barite supply agreement.”

The sale is expected to close in the fourth quarter of 2022 and remains subject to the closing conditions specified in the purchase agreement. Proceeds from the sale are expected to be used for general corporate purposes, including debt reduction, potential growth investments and/or share repurchases under the Company’s current share repurchase program as the Company continues to execute on its strategic plan.

PPHB is serving as financial advisor and Culhane Meadows PLLC is serving as legal advisor to Newpark in this transaction.
