NEWPARK RESOURCES REPORTS 2008 THIRD QUARTER RESULTS
Income from continuing operations increased 53% to $0.13 per diluted share

THE WOODLANDS, TX — October 30, 2008 — Newpark Resources, Inc. (NYSE: NR) today announced results for its third quarter ended September 30, 2008. Total revenues were $211.6 million for the third quarter of 2008 compared to $153.8 million for the third quarter of 2007. The Company reported income from continuing operations of $11.7 million, or $0.13 per diluted share, compared to $7.6 million, or $0.08 per diluted share, in the third quarter of 2007. Net income was $10.4 million, or $0.12 per diluted share, compared to $7.4 million, or $0.08 per diluted share, in the third quarter of 2007.

Paul Howes, President and Chief Executive Officer of Newpark, stated, “I am very pleased with our third quarter results as we continue to realize the benefits from our strategic investments in new markets and revenue streams. Our core drilling fluids and engineering segment performed exceptionally well both domestically and internationally, with revenues increasing 45% year-to-year and 12% sequentially. Meanwhile, we expect to sign the Lot B contract with Petrobras in November, which serves as another key milestone in our efforts to expand into the deepwater market in Brazil.

“Looking ahead, the volatility in credit markets and commodity prices has created an uncertain outlook for drilling activity. Accordingly, we have sharpened our focus on ensuring that we have plans in place to react quickly to market changes and meet the needs of our customers. We believe we are well positioned to continue gaining share in the markets we serve during these unsettling times.”

SEGMENT RESULTS

The Fluids Systems and Engineering segment generated revenues of $189.0 million and a 13.5% operating margin in the third quarter of 2008 compared to revenues of $130.0 million and an 11.9% operating margin during the third quarter of 2007. Third quarter 2008 revenues were driven by strong growth in both the North American and Mediterranean regions. North American revenues increased 43% over the third quarter of 2007 on solid revenue gains from both the U.S. and Canadian markets, while Mediterranean revenues increased 27% compared to the third quarter of 2007. Brazil also contributed to revenue growth, generating a $4.7 million increase in the third quarter of 2008 as the Company continues to expand its presence in the Brazilian market.

The Mats and Integrated Services segment generated revenues of $22.6 million and a 5.0% operating margin in the third quarter of 2008 compared to revenues of $23.8 million and a 19.1% operating margin in the third quarter of 2007. The decline in revenues is attributable to a $1.6 million decrease in composite mat sales, partially offset by higher mat rental and related services revenue. The third quarter 2008 results included $0.9 million of expenses for the transportation of composite mats to the United Kingdom for rental use in the utility industry.

SHARE REPURCHASE PROGRAM UPDATE

As previously announced, Newpark’s Board of Directors approved a stock repurchase program in February 2008, authorizing the Company to purchase up to $25.0 million of outstanding shares of Newpark common stock. During the third quarter of 2008, the Company repurchased 732,195 shares for an aggregate price of $5.1 million. As of September 30, 2008, the Company has repurchased 2,618,195 outstanding shares for an aggregate price of $15.1 million, an average per share price of $5.77.

ENVIRONMENTAL SERVICES UPDATE

On October 23, 2008, the Federal Trade Commission (“FTC”) filed suit seeking a Temporary Restraining Order and Preliminary Injunction to prevent the Company and CCS, Inc. from concluding the previously announced sale of the Company’s environmental services business. The FTC alleges that the proposed combination of CCS and the Company’s environmental services business would have an anti-competitive impact on the alleged markets.

The Company disagrees with the FTC’s position and intends to oppose the FTC’s request to obtain a preliminary injunction to prevent consummation of the proposed transaction.
