Dionex Reports Record First Quarter Net Sales and Earnings Per Share

SUNNYVALE, Calif., Oct. 29, 2008 (GLOBE NEWSWIRE) -- Dionex Corporation (Nasdaq:DNEX) today announced record results of operations for the first quarter ended September 30, 2008.

Net sales for the first quarter of fiscal year 2009 were $93.4 million, an increase of 13% compared with the $82.4 million reported in the first quarter of last year. Currency fluctuations increased sales by $4.9 million, or 6 percentage points, for the first quarter compared with the same period last year. Operating income for the first quarter of fiscal year 2009 was $19.5 million, an increase of 22%, compared with $16.0 million in the first quarter of last year. Diluted earnings per share for the quarter were $0.64, an increase of 21% compared with the $0.53 reported in the same quarter of last year.

During the first quarter of fiscal year 2009, the Company repurchased 201,584 shares of its common stock for $13.3 million. In the first quarter of fiscal 2008, the Company repurchased 257,825 shares of its common stock for $18.6 million. In addition, the Company announced today that its Board of Directors has approved the open market stock repurchase of up to an additional 1,000,000 shares of its common stock. This amount supplements the remaining 343,135 shares under the Company's share repurchase programs previously announced.

Lukas Braunschweiler, President and Chief Executive Officer, commenting on the results, said, "We are very pleased with the way that we started this fiscal year. We reported the highest first quarter sales in the Company's history, growing 13%. We reported very strong growth in our operating profit and earnings in the first quarter and our earnings per share exceeded the high end of our guidance.

"Sales in North America were up slightly in the quarter after very strong growth in the first quarter of last fiscal year. Sales growth in Europe was 15% in reported dollars and 4% in local currency showing a good, solid recovery from a slower start into this fiscal year. Sales in our Asia/Pacific region grew over 20% this quarter in both reported and local currency showing strong growth in virtually all countries; notably in Japan, China, India and Australia.

"Compared to the first quarter of last year, we saw increased demand from customers in all of our various markets, including very strong demand from our food and beverage customers.

"We saw continued strong growth in sales of our ion chromatography products in the first quarter compared to the same quarter last year with sales growing in the mid-teens on a percentage basis, driven by all three global regions and by strong demand for both our systems and consumables products. Our HPLC product line sales grew in the mid-single digits for the quarter supported by solid growth in all three regions.

"We believe that we are well positioned for continued solid organic sales and earnings growth in the remainder of fiscal year 2009. We are maintaining our forecasted organic sales growth of 6-8%. Since our last conference call, the U.S. dollar has strengthened significantly, particularly in the last 30 days. For example, the U.S. dollar has strengthened from $1.55/Euro to $1.27/Euro. Given the dramatic change in currency rates, we are adjusting our reported U.S. dollar sales and diluted earnings per share estimates. Our estimates are based on the following assumptions: (1) currency rates will have a negative 3-4 percent points impact on our reported sales for fiscal year 2009, if currency rates stay as they are now; (2) our gross margin will be in the range of 65%-67% in fiscal 2009; and (3) our tax rate for fiscal year 2009 should be in the range of 35%-36%. Thus, we estimate that net sales will be in the range of $100-$102 million for the second quarter and $385-$393 million for the full fiscal year 2009. We estimate that GAAP diluted earnings per share will be in the range of $0.82-$0.85 for the second quarter and in the range of $2.96-$3.08 for the full year."
