NEWPARK RESOURCES REPORTS FIRST QUARTER 2015 RESULTS

THE WOODLANDS, TX – APRIL 30, 2015 – Newpark Resources, Inc. (NYSE: NR) today announced results for its first quarter ended March 31, 2015. Total revenues for the first quarter of 2015 were $208.5 million compared to $306.2 million in the fourth quarter of 2014 and $242.8 million in the first quarter of 2014. Income from continuing operations for the first quarter of 2015 was $1.0 million, or $0.01 per diluted share, compared to $23.4 million, or $0.25 per diluted share, in the fourth quarter of 2014, and $11.7 million, or $0.13 per diluted share, in the first quarter of 2014.

First quarter 2015 operating results included $2.9 million of pre-tax charges associated with North American workforce reductions. In addition, due to the continued strengthening of the US Dollar, the first quarter 2015 results included $1.6 million of pre-tax foreign currency exchange losses, primarily attributable to the revaluation of inter-company balances due from our Brazilian subsidiary. Further, the foreign currency exchange loss created a pre-tax loss in our Brazilian subsidiary, for which the recording of a tax benefit is not permitted, resulting in an unusually high effective tax rate for the period. Combined, these items reduced first quarter net income by $0.04 per diluted share.

Paul Howes, Newpark’s President and Chief Executive Officer, stated, “The first quarter proved to be very challenging, particularly in the North American Fluids business. North American Fluids revenues were down 41% sequentially, reflecting the sharp reduction in customer drilling activity combined with the effects of weaker pricing, lower wholesale barite sales, and a weaker sales mix, as customers slowed their product purchases and used their on-hand inventory in anticipation of laying down rigs. In response to the sharp decline in customer activity levels, we initiated significant actions to right-size our organization, reducing our North American Fluids Systems workforce by more than 35% since the beginning of the year. Most of the reductions were completed toward the end of the first quarter, so minimal cost benefits were realized in the period. Outside of North America, customer activities and pricing have remained much more stable, although the continued strengthening of the U.S. Dollar has negatively impacted our revenues and profitability across all international regions.

“Despite the challenges in North America, our mats business continued to perform exceptionally well, sustaining operating margins above the 40% level in the first quarter. While the business was impacted by the lower drilling activity and pricing compression in the period, we are continuing our efforts to diversify this business into non-exploration markets and new geographies.

“Meanwhile, our cash flow and liquidity position remain very strong, generating $32 million of operating cash flow in the quarter and ending the period with $92 million of cash on-hand. During the first quarter, we also expanded our U.S. revolving credit facility from $125 million to $200 million, and we currently have no borrowings outstanding under the facility. This strong balance sheet position provides us with exceptional flexibility to continue executing our long-term strategy, despite the challenging North American environment,” concluded Howes.

The Fluids Systems segment generated revenues of $171.9 million in the first quarter of 2015 compared to $261.0 million in the fourth quarter of 2014 and $211.4 million in the first quarter of 2014.

The segment results for the first quarter of 2015 included $2.6 million of pre-tax charges associated with workforce reductions.

The Mats and Integrated Services segment generated revenues of $36.6 million in the first quarter of 2015 compared to $45.1 million in the fourth quarter of 2014 and $31.4 million in the first quarter of 2014.
