SNHY Celebrates 10 years on NASDAQ

SARASOTA, FLA, March 6, 2007 – Sun Hydraulics Corporation (NASDAQ: SNHY) reported financial results for the year and fourth quarter 2006 as follows:

“Fourth quarter orders and shipments finished very strong and our 2006 financial results were even better than we had expected,” said Allen Carlson, Sun’s President and CEO. “While North America continued to hold up, we saw robust demand in Europe and Asia/Pacific. The strong order trends have continued through January and February and we anticipate first quarter 2007 results will continue to outpace the industry. We expect continued double digit growth in Q1 2007. This is exceptional given the strength of last year’s first quarter.”

“The keys to our success have not changed,” Carlson continued. “Shipping reliability, new complementary and differentiated products, a focus on integrated packages, our strong geographic presence and our website continue to help Sun gain market share. In the product area, we are excited about the launch of additional electro-hydraulic products at the Hannover Fair in Germany in April. Having the right products at the right time has been, and continues to be, our focus,” Carlson stated.

“Sun is proud to celebrate 10 years as a public company. During that time we have continued to grow both the top and bottom lines, and have returned to shareholders over $29 million in dividends,” confirmed Carlson. “For long-term investors, the value of an investment in Sun in January, 1997, has grown more than 300%, compared to a return of over 200% on the S&P 500 over the same 10-year period,” Carlson concluded.

Taxes

Year-end tax provision adjustments included additional taxes due from the repatriation of approximately $5 million from our U.K. and German operations. “While our tax rate was slightly higher than expected, we were able to pay down all U.S. debt in the fourth quarter with the cash brought back from Europe,” stated Tricia Fulton, Sun’s CFO. The effect on earnings per share from the year-end tax provision adjustments, including repatriation and other items, was approximately $0.03.

Dividend

On March 3, 2007, Sun Hydraulics Board of Directors declared a $0.10 per share dividend on its common stock. The dividend is payable on April 15, 2007, to shareholders of record as of March 31, 2007.

Outlook

2007 first quarter sales are estimated to be $39 million, a 14% increase over last year. First quarter earnings per share are estimated to be between $0.42 and $0.45 per share, compared to $0.38 per share last year.
