Dionex Reports Record Net Sales and Earnings for the Third Quarter

SUNNYVALE, Calif., May 6, 2010 (GLOBE NEWSWIRE) -- Dionex Corporation (Nasdaq:DNEX) today announced record net sales and earnings for the third quarter and nine months ended March 31, 2010.

For the third quarter of fiscal year 2010, sales were $112.8 million, an increase of 19% compared with the $94.4 million reported in the same quarter of last year. Currency fluctuations increased reported sales by $5.0 million this quarter, or 5%, compared with the third quarter of fiscal year 2009. Our organic growth for the third quarter was 10%. Diluted earnings per share were $0.99 for the third quarter, an increase of 18% compared to the $0.84 reported in the third quarter of last year.

For the first nine months of fiscal year 2010, sales were $312.6 million, an increase of 7% compared with the $290.9 million reported for the first nine months of fiscal year 2009. Overall, currency fluctuations increased reported sales in the first nine months of fiscal year 2010 by approximately $10.6 million, or 4%, compared to the first nine months of fiscal year 2009. Diluted earnings per share were $2.48, an increase of 3% compared with the $2.41 reported in the first nine months of last fiscal year.

During the quarter, the company repurchased 132,308 shares of its common stock for $9.2 million. In the first nine months of fiscal 2010, the company repurchased 476,126 shares of its common stock for $31.2 million.

Frank Witney, President and Chief Executive Officer, commenting on the results, said, "We are very pleased with our strong results for the third quarter. We are beginning to see a good recovery after a period of difficult economic conditions. In fact, our reported sales and earnings per share were the highest quarterly amounts in the company's history. We are particularly pleased with our very strong operating income growth in the quarter of 24% and we expanded our operating income margin to 23.9% of sales for the quarter. These results were at the high end of our guidance for sales and exceeded our guidance for earnings per share.

"Sales in each of our major geographic regions grew in the quarter. Sales in North America showed a strong increase, growing by 18%. European sales were up 13% in reported dollars and 5% in local currency resulting in a nice recovery from prior quarters. Our Asia/Pacific region continued its strong performance growing 27% in reported dollars and 22% in local currency for the third quarter, driven by excellent performance in Japan, China and several other countries.

"Demand increased in all of our customer end markets this quarter. We saw very strong growth in our chemical/petrochemical, electronics and power markets as they rebounded nicely after several quarters of weaker end customer demand. Our environmental, life sciences and food/beverage customers continued to show growth but at more consistent level as they were less affected in prior quarters.

"Sales of ion chromatography products grew by over 20% this quarter driven by strong results in all regions, especially our Asia/Pacific region. Our HPLC sales grew in the mid teens in reported dollars this quarter compared with the third quarter last year, largely as a result of our ESA acquisition. We are very pleased to see growing customer demand for our Ultimate 3000 RSLCnano system and the performance of our ESA acquisition is on track with our projections.

"It was good to see some initial recovery after four difficult quarters resulting from weak economic conditions. While we believe the recovery will be gradual in certain regions, overall we believe we will continue to benefit from improving economies. Our estimates for the fourth quarter and the full fiscal year 2010 are based on the following assumptions: (1) currency rates will have no impact on our reported sales for the fourth quarter, assuming currency rates stay as they are now; (2) our gross margin will be in the range of 66%-67% in the fourth quarter; (3) we will continue to tightly manage expenses in the fourth quarter; (4) our tax rate for the fourth quarter will be in the range of 34%-35%; (5) the acquisition of the ESA business will add $12-$15 million in net sales in fiscal 2010 and be slightly accretive excluding acquisition related costs and additional cost of goods sold from the write-up of inventory totaling approximately $0.06 per diluted share, and (6) current economic conditions wil l continue improving and we will benefit from that improvement. Based on these assumptions, we estimate that net sales will be in the range of $104-$108 million for the fourth quarter of fiscal year 2010 and $417-$421 million for the full fiscal year 2010. We estimate that GAAP diluted earnings per share will be in the range of $0.76-$0.81 for the fourth quarter and we are increasing our estimate for the full year to be in the range of $3.24-$3.29."
