HOUSTON, TX. - March 2, 2011 - Kraton Performance Polymers, Inc. (NYSE: KRA), a leading global producer of styrenic block copolymers, announces financial results for the quarter and year ended December 31, 2010.

2010 FOURTH QUARTER HIGHLIGHTS

“We are pleased with our fourth quarter results, delivering strong volume and revenue growth year-on-year as we continued to make progress in our base business and with our key innovation programs,” said Kevin M. Fogarty, Kraton’s President and Chief Executive Officer. “In closing our first full calendar year as a public company, we posted revenue of $1.2 billion and Adjusted EBITDA of $195 million. Moreover, we continued to position the company for the future by delivering on key strategic initiatives we have established, including continuing our price right strategy, advancing our innovation-based revenue, adding critical capabilities within the company, flawlessly executing on our capital investment programs and developing plans for future expansion, including Asian hydrogenated styrenic block copolymer capacity,” added Fogarty. “Building upon the momentum of 2010, in February we completed a very successful refinancing of our bank and public debt, extending our maturities and adding significant liquidity and financial flexibility. As a result, we enter 2011 as an even stronger company, well-positioned for further growth.”

4Q 2010 versus 4Q 2009 Results

Sales revenues in the fourth quarter 2010 were $288 million, an increase of approximately 21% compared to the fourth quarter 2009. The increase in sales revenues compared to the fourth quarter 2009 was primarily the result of higher sales volumes and the impact of price increases implemented in response to rising raw material costs and other factors. Sales volume in the fourth quarter 2010 was 67 kilotons, up 10% compared to the fourth quarter 2009.

Adjusted EBITDA in the fourth quarter 2010 was $34 million, or 12% of revenue, compared to $35 million, or 14% of revenue in the fourth quarter 2009. The spread between LIFO and FIFO had a negative impact on fourth quarter 2010 Adjusted EBITDA of $8 million, and a positive impact of $13 million in the fourth quarter 2009.

Fourth quarter 2010 net income was $10 million or $0.32 per diluted share, compared to a fourth quarter 2009 net loss of $2 million or $(0.07) per diluted share. Fourth quarter 2010 earnings per share were negatively impacted by approximately $0.12 per share associated with restructuring costs and other non-recurring charges.

FY 2010 versus FY 2009 Results

Sales revenues in 2010 were $1,228 million, an increase of approximately 33% compared to 2009. The increase in sales revenues compared 2009 was primarily the result of higher sales volumes and increased pricing in response to rising raw material costs and other factors. Full year 2010 sales volume was 307 kilotons, up 18% compared to 2009.

Adjusted EBITDA in 2010 was $195 million or 16% of revenue, compared to $91 million or 9% of revenue in 2009.

Full-year 2010 net income was $97 million or $3.07 per diluted share, compared to a full-year 2009 net loss of $0.3 million or $(0.01) per diluted share. Full-year 2010 earnings per share were negatively impacted by approximately $0.19 per share associated with restructuring costs and other non-recurring charges.

Cash Flow

During the fourth quarter, net cash provided by operating activities was $35 million, compared to net cash provided by operating activities of $32 million in the fourth quarter of 2009 and $72 million in the third quarter of 2010. Net capital expenditures in the fourth quarter 2010 were $23 million versus $17 million in the fourth quarter 2009 and $13 million in the third quarter 2010. Net capital expenditures in 2010 were $56 million, compared to $50 million in 2009.

END USE MARKET INFORMATION

Revenue in our Advanced Materials end use market increased $17 million or approximately 23% to $92 million in the fourth quarter 2010 compared to the fourth quarter 2009.

“Revenue in our Advanced Materials end use market increased, reflecting volume recovery in our base business as well as price improvement and incremental volume growth, led by personal care and consumer disposable applications,” said Fogarty. “We also saw volume growth in our innovative product offerings such as alternatives for PVC used in wire and cable and medical applications.”

Revenue in our Adhesives, Sealants and Coatings end use market increased $11 million or approximately 13% to $93 million in the fourth quarter 2010 compared to the fourth quarter 2009.

“In our Adhesives, Sealants and Coatings end use market, the increase in revenue was largely driven by increased pricing. We did experience volume growth in personal care and in specialty tape applications. In response to the industry shortage of certain tackifier resins which emerged in the second half of 2010, we completed development of alternative product formulations that work with a broad spectrum of available resins,” said Fogarty. “We also continue to be encouraged by the increase in demand for our innovative products sold into protective film applications,” Fogarty added.

Revenue in our Paving and Roofing end use market increased $15 million or approximately 31% to $64 million in the fourth quarter 2010 compared to the fourth quarter 2009.

“Revenue growth in our Paving & Roofing end use was driven by increased roofing volume in Europe and to a lesser extent in North America, and by price increases implemented to offset higher monomer costs,” said Fogarty. “In North America, paving activity was hindered by a lack of incremental funding available for infrastructure projects.”

Revenue in our Emerging Businesses end use market increased $3 million or approximately 14% to $27 million in the fourth quarter 2010 compared to the fourth quarter 2009.

“In the fourth quarter we continued to see strong demand for our Cariflex^TM isoprene rubber and isoprene rubber latex, which is used in high-end surgical gloves, condoms and medical components,” said Fogarty. “We look forward to completion of the isoprene rubber line conversion at our Belpre, Ohio facility and completion of the isoprene rubber latex capacity expansion in Paulinia, Brazil in the coming months, and we are anticipating our next expansion project to support further growth in this business.”

OUTLOOK

“Based upon existing market trends, we currently expect that our first quarter 2011 sales volume will be up 5-7% compared to the first quarter 2010,” said Fogarty. “In addition, we believe pricing for our three primary feedstocks, on average, will be higher in the first quarter of 2011 than in the fourth quarter of 2010, as monomer prices reflect factors such as higher crude oil prices and other supply/demand fundamentals such as the shortage of natural rubber, which has increased demand for butadiene and isoprene used in the production of natural rubber substitutes. As a result of the movement in raw material prices, we expect to recognize a LIFO to FIFO benefit in the first quarter of 2011. Finally, we expect capital expenditure to be $80 to $85 million in 2011, largely driven by completion of the Cariflex^TM isoprene rubber and latex projects in Belpre, Ohio and Paulinia, Brazil respectively, on-going expenditures in our four-year process control system upgrades also in Belpre, and initial expenditures associated with our anticipated Asian HSBC expansion project.”

USE OF NON-GAAP FINANCIAL MEASURES

This earnings release includes the use of both GAAP (generally accepted accounting principles) and non-GAAP financial measures. The non-GAAP financial measures are EBITDA and Adjusted EBITDA. In each case the most directly comparable GAAP financial measure is net income/loss. A table included in this earnings release reconciles these non-GAAP financial measures with the most directly comparable GAAP financial measure.

We consider EBITDA and Adjusted EBITDA important supplemental measures of our performance and believe they are frequently used by investors and other interested parties in the evaluation of companies in our industry. EBITDA and Adjusted EBITDA have limitations as analytical tools, and you should not consider them in isolation, or as a substitute for analysis of our results under GAAP in the United States. EBITDA and Adjusted EBITDA presented in this earnings release may differ from EBITDA amounts calculated by us under our debt instruments.
