“We saw a significant surge in demand in the first quarter that has continued through April and into May” reported Allen Carlson, Sun Hydraulics’ President and CEO. “Our major focus continues to be on delivery performance and satisfying our customers’ needs.”

“We remain committed to our global strategy of expanding our international footprint. International sales were up 25% over last year with sizable growth in the European and Asian markets,” Carlson added. “Domestic sales also continue to be strong, with a 10% year over year increase. With order rates remaining steady at a high level and our short book-to-ship cycle, we expect second quarter results will continue to show strength.”

“In April, we released the first products that have resulted from our WhiteOak joint venture, which we entered into last year,” Carlson explained. “These complementary electronic products are just the beginning of new, innovative technologies that will result from our association with WhiteOak.”

2006 second quarter sales are estimated to be in the range of $36 million, a 16% increase over the same period last year. Second quarter earnings per share are estimated to be between $0.39 and $0.41 per share, compared to $0.32 per share last year.
