Sun Hydraulics to Supply Cartridge Valves to Mannesmann Rexroth Mannesmann Rexroth to Manufacture Products to fit Sun Cavity

SARASOTA, FLA, April 8, 1999 – Sun Hydraulics Corporation (NASDAQ: SNHY) today announced that it will sell selected screw-in cartridge valve products to Mannesmann Rexroth, with headquarters in Lohr, Germany, for incorporation into its fluid power systems. Concurrently, Rexroth announced that it will use the family of Sun cavities for its newly developed solenoid switching and proportional screw-in cartridge valves.

Rexroth, widely regarded as a world leader in the manufacture of high performance hydraulic components and systems, will introduce its new cartridge valve program, which will be interchangeable and directly competitive with Sun, at the Hannover Fair, April 19 – 25, 1999, in Hannover, Germany.

Rexroth’s acceptance of the Sun Hydraulics family of screw-in cartridge cavities and the provision of an alternate source for these cartridges is seen as a positive influence in the marketplace. In this regard, Rexroth recognizes that the independence of Sun Hydraulics and Rexroth will positively affect market acceptance of cartridges that fit in Sun cavities by providing OEMs with alternate suppliers.

“The decision by Rexroth to use the Sun Hydraulics family of cavities for its new products is due to technical advantages of the Sun cavity compared to current ISO standard and de facto industry standard cavities,” said Bob Koski, Chairman of Sun Hydraulics. “This decision and the possibility that Rexroth may manufacture additional cartridge valves to fit Sun’s cavities are seen as having long-term strategic advantages. Rexroth’s new solenoid cartridges will be directly competitive with our solenoid cartridge valves, which we will also introduce at the Hannover Fair. We believe the direct competition between Rexroth and Sun will help accelerate the acceptance of these products in the world market.”

“We have encouraged Rexroth to incorporate our screw-in cartridge valves into its systems solutions,” said Sun Hydraulics President Clyde Nixon. “Rexroth has a comprehensive international systems and component distribution network and participates in many markets where Sun currently has limited penetration. Rexroth and Sun will continue to expand the market for screw-in cartridge valves, and, over the course of the next few months, will further explore cooperative efforts on selected programs including non-exclusive manufacturing license agreements. “While Sun is pleased with the long-term implications of this association, we do not anticipate it will have a material impact on short-term revenues or profits,” Nixon continued. ”At the present time, our orders continue at fourth quarter levels. First quarter financial results should be in line with, or slightly above, analysts’ forecasts, reflecting strong shipments resulting from a further reduction in our backlog.”

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 mobile and industrial machinery.
