REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Participants and Administrator of the

Sun Hydraulics Corporation 401(k) and

ESOP Retirement Plan:

We have audited the accompanying statement of net assets available for benefits of Sun Hydraulics Corporation 401(k) and ESOP Retirement Plan as of December 31, 2006, and the related statement of changes in net assets available for benefits for the year then ended. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Plan is not required to have, nor have we been engaged to perform an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of Sun Hydraulics Corporation 401(k) and ESOP Retirement Plan as of December 31, 2006, and the changes in net assets available for benefits for the year then ended, in conformity with accounting principles generally accepted in the United States of America.

Our audit was conducted for the purpose of forming an opinion on the basis financial statements taken as a whole. The supplemental schedule of assets (held at end of year) is presented for purposes of additional analysis and is not a required part of the basic financial statements, but is supplementary information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule has been subjected to the auditing procedures applied in the audit of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

SUN HYDRAULICS CORPORATION 401(K) AND ESOP RETIREMENT PLAN

NOTES TO THE FINANCIAL STATEMENTS

DECEMBER 31, 2006 AND 2005

1.	Description of Plan

The following description of the Sun Hydraulics Corporation 401(k) and ESOP Retirement Plan (f/k/a Sun Hydraulics Corporation Retirement Plan) (the “Plan”) provides only general information. Participants should refer to the Plan agreement, as amended, for a more complete description of the Plan’s provisions.

General

The Plan became effective January 1, 1979. The Plan is a defined contribution 401(k) plan covering employees of its sponsor, Sun Hydraulics Corporation (“Corporation”), who have completed six months employment and reached the age of 18. Employees may enroll in the Plan effective on the first day of each calendar quarter following their sixth month of employment. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA).

During 2004, the Corporation adopted the Employee Stock Ownership Plan (“ESOP”). Under the ESOP, the Corporation may contribute on a discretionary basis company common stock to all employees eligible to participate in the Plan. The ESOP is a non-participant directed investment as the Company makes all contributions to the fund. Contributions have a one year restriction on the sale of stock, with limited exceptions.

The sponsor company common stock is contributed into a unitized stock fund. The fund is made of approximately 95-97 percent in Sun Hydraulics Corporation stock, with the remaining amount invested in short-term money market funds. The cash reserve in the account helps support routine transfer and withdrawal activity. The value of the fund bears a relationship to, but is not the same as the price of Sun Hydraulics stock. At December 31, 2006, the fund held 165,528 shares of Sun Hydraulics Corporation common stock with a price of $20.51 per share as of such date. At December 31, 2005, the fund held 137,480 shares of Sun Hydraulics Corporation common stock with a price of $19.33 per share as of such date. The shares held reflect a three-for-two stock split, effected in the form of a 50% stock dividend, which became effective on July 15, 2005.

The Plan is administered by the Employee Benefits Committee (the “Committee”) except in connection with the acquisition, retention or disposition of Corporation stock held by the Plan, with respect to which the Board of Directors retained authority. The Committee is composed of six employees of the Corporation appointed by the Corporation’s Board of Directors. Charles Schwab Trust Company (the “Trustee”) is the current trustee for the Plan. Schwab Retirement Plan Services, Inc. provides the recordkeeping, accounting, and the telephone and Internet exchange features of the Plan.

Contributions

Salary deferral contributions are made by participating employees through payroll deductions in amounts authorized by the employees. The Plan allows participants to make pre-tax contributions from 1% to 100% of their salary not to exceed statutory limits. Pre-tax contributions, of up to 6% of the employee’s salary (depending on length of service), are matched by the Corporation. Matching contributions are based on the years of service as listed in the following schedule:


Years of Service	% Match
Less than three years	3	%
After three years	4	%
After five years	5	%
After seven or more years	6	%

Additional contributions may be made by the Corporation on a discretionary basis. During 2006 and 2005, the Corporation contributed $1,385,527 and $1,180,268, respectively, to the ESOP in the form of company stock. The total amounts are shown as a contribution receivable for their respective plan year.

Participant Accounts

Each participant’s account is credited with the participant’s contribution, any employer’s contribution and an allocation of Plan earnings or losses. Allocations are based on the participant’s account balance.

Vesting

Participants are immediately vested in their voluntary contributions plus actual earnings thereon. Participants are vested in employer matching contributions and discretionary employer ESOP contributions based upon years of service defined in the Plan, as follows:


Years of Service	Vesting %
Less than 1	0	%
1	20	%
2	40	%
3	60	%
4	80	%
5 or more	100	%

Payment of Benefits

If a participant ceases to be employed by the Corporation for any reason other than death or total and permanent disability, prior to satisfying the age and service requirements for early or normal retirement, the terminated participant may elect to receive lump-sum or periodic payments of the participant’s vested account balance. Withdrawals may be subject to tax withholdings and penalties.

Benefits may be paid upon death, disability, termination or retirement to the participants or their beneficiaries, in lump-sum amounts or periodic payments. Under certain circumstances, hardship withdrawals are allowed from the Plan.

Investment Options

The participants, upon enrollment in the Plan, elect to invest their contributions, in multiples of five (5) % increments, in the investment options provided by the Plan. Investments in sponsor company common stock is not a participant directed investment option.

Participant Loans

A participant may receive a loan based on the loan program set forth by the Plan. The minimum loan is $1,000 and the maximum is $50,000, not to exceed 50% of the participant’s vested account balance. Loans are repaid through payroll deductions over a maximum of five (5) years. A participant can have only one loan outstanding. Current loans bear interest at rates between 6.00% and 10.25%.

Plan Expenses

The Plan pays the account administrative service fee from income earned by the Plan. The Corporation pays the administrative service fee, legal and accounting fees, and other expenses on behalf of the Plan.

Forfeitures

At December 31, 2006, and December 31, 2005, forfeited nonvested accounts totaled $13,201 and $3,495, respectively. Account balances will revert back to the Plan and will be used to pay reasonable administrative expenses of the Plan, any excess will be used to reduce the employer’s matching contributions.

2.	Summary of Accounting Policies

Basis of Accounting

The accompanying financial statements are presented on the accrual basis of accounting.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

Investments

The Plan’s investments are held by the Trustee. The Plan’s investments are stated at fair value. If available, quoted market prices are used to value investments. For investments without quoted market prices, the net asset value is calculated and verified on a daily basis by the respective trusts and reported to the Trustee. Participants’ loans are valued at cost which equals fair value.

Investment income and gains and losses are allocated among participants on the basis of individual participant account balances. Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividend income is recognized when earned.

Payment of Benefits

Benefits are recorded when paid.

Net Appreciation in Fair Value of Investments

The Plan presents, in the statements of changes in net assets available for benefits, the net appreciation in fair value of its investments consisting of interest, dividends, the realized gains (losses) and the unrealized appreciation (depreciation) on those investments.

3.	Investments

Investment balances that represent five percent or more of the net assets available for benefits are as follows:


	2006		2005
Julius Baer International Equity	$	5,741,135	$	3,990,051
Schwab S&P 500 Index Investor		5,221,055		5,354,364
Sponsor Company Comon Stock		3,530,175		2,770,845
Jensen		3,180,833		2,668,094
Schwab Stable Value Fund		3,007,978		2,924,841
Janus Mid Cap Value Investor		2,800,030		2,528,493
JPMorgan Core Bond Fund		2,664,567		1,964,929
Dreyfus Small Company Value		2,303,775		2,656,474

During the years ended December 31, 2006 and December 31, 2005, the Plan’s investments (including gains and losses on investments bought and sold, as well as held during the year) appreciated in value as follows:


	2006	2005
Mutual funds	3,674,046	1,072,219
Common/collective trust fund	127,136	14,953
Sponsor company common stock	218,029	1,461,982

Net change in fair value	4,019,211	2,549,154

A portion of the Schwab Stable Value Fund, a common collective trust (“CCT”), is invested in guaranteed investment contracts (“GICs”) which provide for benefit-responsive withdrawals by plan participants at contract value. The GICs are valued at contract value. The average yield for the CCT was 4.32% and 3.51% for the years ended December 31, 2006 and December 31, 2005, respectively. The CCT’s crediting interest rates on investments ranged from 2.25% to 7.25% and 2.3% to 6.45% on December 31, 2006, and December 31, 2005, respectively.

4.	Non-participant Directed Investments

Information about the net assets and the significant components of the changes in net assets relating to the non-participant directed investments is as follows:


	Year Ended December 31,
	2006			2005
Changes in net assets:
Contributions	$	1,183,114		$	1,059,771
Net appreciation		218,029			1,461,982
Benefits paid to participants		(244,215	)		(142,659	)
Administrative Expenses		(2,122	)		(1,049	)
Loans taken		(112,224	)		(16,236	)
Forfeitures		(26,087	)		(13,404	)
Transfers to participant directed investments		(257,165	)		(80,744	)

	$	759,330		$	2,267,661

5.	Tax Status of the Plan

The Internal Revenue Service has determined and informed the Corporation by letter dated October 3, 2005, that the Plan and related trusts were designed in accordance with applicable sections of the Internal Revenue Code. Although the Plan has been amended since receiving the letter, the Corporation believes that the Plan is designed and is currently being operated in compliance with the applicable requirements of the Internal Revenue Code.

6.	Plan Termination

Although it has not expressed any intent to do so, the Corporation has the right under the Plan to amend or discontinue the Plan at any time and to terminate the Plan, subject to the terms of ERISA. In the event of Plan termination, the participants will become 100% vested in their accounts and net assets of the Plan will be distributed to the participants and beneficiaries of the Plan.

7.	Related Party Transactions

Certain Plan investments are shares of mutual funds and a common/collective trust managed by the Trustee and shares of the Company’s common stock; and therefore, these transactions qualify as party-in-interest.

8.	Risks and Uncertainties

The Plan invests in various investment securities. Investment securities are exposed to various risks such as interest rate, market, and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participants’ account balances and the amounts reported in the statements of net assets available for benefits.

9.	Subsequent Events

Effective January 1, 2007, the Plan was amended to provide for automatic enrollment of eligible employees through a negative election procedure. Also effective January 1, 2007, the Plan was amended to remove the one year restriction on the sale of stock within the ESOP to allow for immediate diversification of investments.
