NEWPARK RESOURCES REPORTS NET INCOME OF
$0.16 PER DILUTED SHARE FOR THE FIRST QUARTER 2011

THE WOODLANDS, TX — April 28, 2011 — Newpark Resources, Inc. (NYSE: NR) today announced results for its first quarter ended March 31, 2011. Total revenues were $202.7 million for the first quarter of 2011, compared to $194.5 million for the fourth quarter of 2010 and $160.8 million for the first quarter of 2010. Net income for the first quarter of 2011 was $15.9 million, or $0.16 per diluted share, compared to net income for the fourth quarter of 2010 of $14.8 million, or $0.15 per diluted share, and net income for the first quarter of 2010 of $7.8 million, or $0.09 per diluted share.

Paul Howes, President and Chief Executive Officer of Newpark, stated, “Solid performance in our Drilling Fluids and Mats and Integrated Services businesses helped drive strong year-over-year and sequential growth in the first quarter of 2011. In North America, we posted 12% sequential growth in revenues, despite the expected decline in our Environmental Services segment. Internationally, we experienced a sequential decline from our record revenue level achieved in the fourth quarter of 2010, consistent with our expectation.

“Our recent completion of the Rheochem acquisition provides us with a footprint in the growing Asia Pacific market to support the continued expansion of our international operations,” added Howes. “Meanwhile, we’ve continued with the roll-out of Evolution^tm, our high performance water-based drilling fluid system, with customers now running or evaluating the system in several major North American drilling basins.”

SEGMENT RESULTS

The Fluids Systems and Engineering segment generated revenues of $170.5 million in the first quarter of 2011 compared to $162.8 million in the fourth quarter of 2010 and $136.3 million in the first quarter of 2010. North American revenues increased 14% sequentially in the first quarter of 2011, including an $11.7 million, or 12%, improvement in the U.S. along with $4.0 million from seasonal improvements in Canada. International revenues declined 15% from the fourth quarter of 2010, driven by the timing of customer projects in Brazil and lower revenues in Italy and areas of North Africa, due in part to political and social unrest in the region. Compared to the first quarter of 2010, revenues increased 25% in both our North American and international operations. Segment operating income was $19.2 million (11.3% margin) in the first quarter of 2011 compared to $16.8 million (10.3% margin) in the fourth quarter of 2010 and $12.4 million (9.1% margin) in the first quarter of 2010.

The Mats and Integrated Services segment generated revenues of $23.1 million in the first quarter of 2011 compared to $20.6 million in the fourth quarter of 2010 and $13.6 million in the first quarter of 2010. Revenues for the segment were up 12% from the fourth quarter of 2010, driven primarily by a $2.0 million increase in composite mat sales. Compared to the first quarter of 2010, segment revenues were up 69%. Segment operating income was $11.8 million (51.1% margin) in the first quarter of 2011 compared to operating income of $10.3 million (50.2% margin) in the fourth quarter of 2010 and $2.7 million (19.9% margin) in the first quarter of 2010.

The Environmental Services segment generated revenues of $9.1 million in the first quarter of 2011 compared to $11.1 million in the fourth quarter of 2010 and $10.9 million in the first quarter of 2010. The sequential decline in revenues is primarily attributable to lower waste disposals associated with the Deepwater Horizon oil spill. Segment operating income was $1.6 million (17.8% margin) in the first quarter of 2011 compared to operating income of $2.6 million (23.4% margin) in the fourth quarter of 2010 and $2.7 million (24.7% margin) in the first quarter of 2010.
