NEWPARK RESOURCES REPORTS FIRST QUARTER 2007 RESULTS

     THE WOODLANDS, TX — MAY 3, 2007 — Newpark Resources, Inc. (NYSE: NR) today announced results for the first quarter ended March 31, 2007.

     Total revenues were $171.8 million for the first quarter of 2007 compared to $166.5 million for the first quarter of 2006. Income from continuing operations was $7.5 million in the first quarter of 2007, or $0.08 per share. Excluding $2.4 million of legal costs associated with the 2005 accounting restatement and the recent agreement to settle the resulting litigation, first quarter 2007 income from continuing operations was $9.0 million, or $0.10 per diluted share, as set forth on the attached Non-GAAP Earnings Reconciliation. Income from continuing operations for the first quarter of 2006 was $6.5 million, or $0.07 per share.

     Paul Howes, President and Chief Executive Officer of Newpark, stated, “We are pleased to report our continued improvement in operating results for the first quarter of 2007 on record revenues, while we have also maintained our focus on cash management, reducing our total debt by $18 million in the quarter. The settlement of the shareholder litigation announced last month allows our team to focus 100% of our efforts on increasing shareholder value. Highlights for the quarter include the awarding of a new contract with a major oil company to provide fluid systems and engineering support to their operations in the U.S., securing a three-year deepwater offshore contract in the Gulf of Mexico, and on the international front, winning our first trials in Egypt.”

     The Fluid Systems and Engineering segment and Mats and Integrated Services segment generated operating margins of 13.3% and 15.8%, respectively, in the first quarter of 2007. These results represent improvements in both segments from the 11.0% operating margins generated by each segment during the first quarter of 2006.

     Howes added, “The results from the Environment Services business were also very strong in the first quarter of 2007, generating an operating margin of 18.0%, compared to an 11.7% operating margin generated in the first quarter of 2006. Meanwhile, the sale process related to the Environmental Services business continues to progress.

     “We continue to drive our corporate strategy and initiatives that were announced in our fourth quarter release and conference call. By finalizing the settlement of our shareholder litigation and completing the sale of our Environmental Services business, we will be well positioned to execute the next steps of our strategy and continue to improve shareholder value,” concluded Howes.
