Sun Hydraulics Corporation Reports Second Quarter Net Income of $0.12 Per Share

SARASOTA, FLA, August 4, 2003 -Sun Hydraulics Corporation (NASDAQ: SNHY) today
announced that sales for the second quarter ended June 28, 2003, were $18.9
million, an increase of 15.2% from the first quarter and a 8.6% increase from
the same quarter last year. Net income was $0.8 million, equal to net income for
the same quarter last year and a $0.5 million increase from last quarter. Net
income included a charge for the write off of development costs for an
application software project in the United Kingdom. Excluding this write off,
net income for the second quarter would have been $1.1 million, or 5.6% of
sales, compared to net income of 4.4% of sales for the same quarter last year.
Basic and diluted earnings per share for the quarter ended June 28, 2003, were
$0.13 and $0.12, respectively, compared to $0.12 for the same period last year.

Allen Carlson, Sun Hydraulics' president commented, "We believe that Sun is
gaining market share in some market segments, particularly central Europe, where
sales are increasing in the face of difficult economic times. Sales in all our
international operations, adjusted for the effect of currency changes, increased
12% this quarter compared to the same quarter last year. We still have not seen
signs of recovery in the North American manufacturing sector of the economy.
Sales in the United States operation this quarter were comparable with those in
the same quarter last year."

Carlson continued, "Sun's prime or variable manufacturing costs in the United
States decreased as a percent of sales in the current quarter compared to the
same quarter last year. This is an indication of Sun's productivity improvements
and our ability to significantly improve operating margins as the economy
recovers and the top line grows."

Software Write Off

Approximately $0.4 million of capitalized software costs related to upgrading
the integrated manufacturing system in the United Kingdom operation was written
off in the second quarter. The installation of this highly customized software
was aborted due to major flaws in the system. The Company has decided that it is
not feasible to continue this project and intends to seek remedy from the
software developer.





Outlook

Sales for the third quarter are projected to be $17.0 million, with net income
of $0.06 per share, compared to third quarter 2002 sales and net income of $16.0
million and $0.08 per share. The anticipated decrease in net income, despite the
higher sales volume and increased productivity, is attributed to increased
marketing and administrative costs, including $0.3 million related to the
Company's re-capitalization and special dividend distribution.

FORWARD-LOOKING INFORMATION

Certain oral statements made by management from time to time and certain
statements contained herein that are not historical facts are "forward-looking
statements" within the meaning of Section 21E of the Securities Exchange Act of
1934 and, because such statements involve risks and uncertainties, actual
results may differ materially from those expressed or implied by such
forward-looking statements. Forward-looking statements, including those in
Management's Discussion and Analysis of Financial Condition and Results of
Operations are statements regarding the intent, belief or current expectations,
estimates or projections of the Company, its Directors or its Officers about the
Company and the industry in which it operates, and assumptions made by
management, and include among other items, (i) the Company's strategies
regarding growth, including its intention to develop new products; (ii) the
Company's financing plans; (iii) trends affecting the Company's financial
condition or results of operations; (iv) the Company's ability to continue to
control costs and to meet its liquidity and other financing needs; (v) the

to changes in customer demand domestically and internationally, including as a
result






of standardization. Although the Company believes that its expectations are
based on reasonable assumptions, it can give no assurance that the anticipated
results will occur.

Important factors that could cause the actual results to differ materially from
those in the forward-looking statements include, among other items, (i) the
economic cyclicality of the capital goods industry in general and the hydraulic
valve and manifold industry in particular, which directly affect customer
orders, lead times and sales volume; (ii) conditions in the capital markets,
including the interest rate environment and the availability of capital; (iii)
changes in the competitive marketplace that could affect the Company's revenue
and/or cost bases, such as increased competition, lack of qualified engineering,
marketing, management or other personnel, and increased labor and raw materials
costs; (iv) changes in technology or customer requirements, such as
standardization of the cavity into which screw-in cartridge valves must fit,
which could render the Company's products or technologies noncompetitive or
obsolete; (v) new product introductions, product sales mix and the geographic
mix of sales nationally and internationally; and (vi) changes relating to the
Company's international sales, including changes in regulatory requirements or
tariffs, trade or currency restrictions, fluctuations in exchange rates, and tax
and collection issues. Further information relating to factors that could cause
actual results to differ from those anticipated is included but not limited to
