Exhibit 99.1 FOR RELEASE: Immediately Contact: Richard K. Arter Investor Relations 941-362-1200 Clyde G. Nixon President 941-362-1200 SUN HYDRAULICS CORPORATION REPORTS $0.11 EARNINGS PER SHARE ON $18.5 MILLION 1ST QUARTER SALES SARASOTA, FLA, May 12, 1999 - Sun Hydraulics Corporation (NASDAQ: SNHY) today announced net sales were $18.5 million for the quarter ended April 3, 1999, representing a 3.5% decrease compared to first quarter 1998 net sales. Net income for the first quarter of 1999 was $0.7 million, compared to $1.6 million in the same quarter of 1998 and $0.8 million in the fourth quarter of 1998. Both basic and diluted earnings per share for the first quarter of 1999 were in line with expectations at $0.11. "First quarter shipments exceeded incoming orders, which continued at the same level as the fourth quarter of 1998," said Sun Hydraulics President Clyde Nixon. "Profit margins were similar to the fourth quarter of 1998, and, as we said in our last release, we do not expect to see margin improvements until the second half of the year. "We anticipate reduced shipping levels in the second quarter as shipments will more closely reflect incoming orders which we believe are being affected by distributor inventory reductions. Additionally, productivity in the second quarter will be affected by the implementation of a new Y2K compliant integrated software system in the United States operations in May. Our productivity improvement initiatives remain on track for the second half of the year," Nixon concluded. Sun Hydraulics Corporation, with manufacturing and distribution facilities in Sarasota and Manatee County, Florida, Coventry England, Erkelenz, Germany and Incheon, Korea, is a leading designer and manufacturer of high performance screw-in hydraulic cartridge valves and manifolds for worldwide industrial and mobile markets.
