OVERVIEW

Sun Hydraulics Corporation is a leading designer and manufacturer of high-performance screw-in hydraulic cartridge valves and manifolds, which control force, speed and motion as integral components in fluid power systems. The Company sells its products globally through wholly-owned subsidiaries and independent distributors. Sales outside the United States for the year ended December 29, 2007, were approximately 58% of total net sales.

Approximately 66% of product sales are used by the mobile market, which is characterized by applications where the equipment is not fixed in place, the operating environment is often unpredictable, and duty cycles are generally moderate to low. Some examples of mobile equipment include off-road construction equipment, fire and rescue equipment and mining machinery.

The remaining 34% of sales are used by industrial markets, which are characterized by equipment that is fixed in place, typically in a controlled environment, and which operates at higher pressures and duty cycles. Automation machinery, metal cutting machine tools and plastics machinery are some examples of industrial equipment. The Company sells to both markets with a single product line.

Company Focus

In recent years, the Company has realized robust growth in all areas of the world. Management believes there are five key reasons why:

• Product availability and on-time delivery performance,

• New products, especially electrically actuated products,

• Increased sales of integrated packages,

• Our geographic presence, and

• Our website.

The company is continuously engaged in efforts to improve productivity to enhance productive capacity and be in the best position to be able to respond to marketplace demand. Company engineering and manufacturing personnel redesign existing products, where necessary, to improve manufacturability. New product design efforts include personnel from engineering, manufacturing and marketing to help reduce the time and effort required to release products to the market. These on-going activities enable the Company to maintain a level of delivery performance and shipping reliability that it believes differentiates it from its competitors.

The Company continues to add to its electrically actuated hydraulic valve offerings with new products, including different types of solenoid and proportional valves and valves with position sensing devices. Electrically actuated cartridges help create new system opportunities as they enable the Company to offer complete integrated valve packages which could not be offered previously. The addition of electrically actuated hydraulic products allows integrated packages to be designed with 100% Sun content. In addition to electrically-actuated products, the Company routinely adds other new complementary products to its cartridge valve and manifold portfolio.

The Company has wholly-owned companies in North America, Europe and the Far East, augmented by what management believes to be the finest distribution network in the fluid power industry. In 2007, the Company opened a sales office in Bangalore, India. The Company's distributors are particularly skilled in applying products and developing integrated solutions for the local market. Through its wholly-owned companies and global distribution network, the Company is able to service all major industrialized market areas.

The Company's major marketing tool is its website, www.sunhydraulics.com. The Company's website is developed to appeal to and be used by design engineers. It provides all the detailed technical information and specifications to select, apply and obtain Sun products, 24 hours a day, seven days a week. The website continues to evolve by adding greater levels of detail in technical information and configuration capability.

Industry conditions

Demand for the Company's products is dependent on demand for the capital goods into which the products are incorporated. The capital goods industries in general, and the fluid power industry specifically, are subject to economic cycles. According to the National Fluid Power Association (the fluid power industry's trade association in the United States), the United States index of shipments of hydraulic products increased 1% and 9% in 2007 and 2006, respectively. The index of shipments of hydraulic products increased 13% for the three months period ending June 2008, compared to the same period of the prior year.

The Company's order trend has historically tracked closely to the United States Purchasing Managers Index (PMI). The index decreased to 50.2 in June 2008 compared to 56.0 in June 2007. In July 2008, the index decreased to 50.0. When PMI is over 50, it indicates economic expansion; when it is below 50, it indicates contraction in the economy.

European and Asian sales were both up over 20% in the second quarter and contributed more than 60% to Sun's total growth for the period. The North American rebound that occurred early in the year continued to gain strength last quarter and domestic sales were up 13.5% compared to last year.

Profitability continued to benefit from the gross margin leverage resulting from the incremental sales volume. Sales for the first half of 2008 were up 19%. Demand for Sun products has outpaced the industry for several years and remains strong. Management believes they have established the fundamentals that will allow the Company to continue to grow, gain market share, and outpace the industry.

Outlook

Sun's products are used in diversified equipment markets around the globe. Many of these markets, such as mining and energy, remain strong and demand is high. In other markets, such as equipment used in residential and commercial construction, Sun has begun to see some softening.

The diversity of the Company's end markets, both geographically and the segments in which it participates, is pivotal to maintaining Sun's growth.

Third quarter 2008 sales are estimated to be approximately $45 million and earnings per share are estimated to be in the range of $0.35 to $0.37. This would represent an increase of approximately 9% in sales and 13% in earnings per share over last year.

Third quarter earnings per share include the U.S. income taxes due on the repatriation of foreign earnings from the German subsidiary as noted in Note 13.

COMPARISON OF THE THREE MONTHS ENDED JUNE 28, 2008 AND JUNE 30, 2007

Net Sales

Net sales were $51.6 million, an increase of $8.1 million, or 18.7%, compared to $43.4 million in 2007. The increase was due in large part to the continued growth of international sales, particularly in Europe and Asia, and increased growth in sales to North America.

European sales increased 24.9%, or $3.4 million, to $17.1 million. Sales to Germany increased 31.0%, to the U.K. 15.4%, and to France 3.0%. Significant increases were also noted in Austria, Finland and Norway.

Asian sales continued to grow, increasing 21.5%, or $1.7 million, to $9.6 million. Sales to China increased 247.3%, while domestic sales in Korea decreased 4.0%.

North American sales increased 13.5%, or $2.8 million, to $23.6 million.

Gross Profit

Gross profit increased $4.8 million, or 33.4%, to $19.1 million. Gross profit as a percentage of net sales increased to 37.0% in the second quarter of 2008, compared to 32.9% in the second quarter last year. Increases in gross profit were primarily due to fixed cost absorption from higher sales volume, productivity improvements in the U.S., lower material costs in the German operation due to the strength of local currencies against the U.S. dollar for material purchases made in U.S. dollars, and a price increase that occurred in January 2008.

Selling, Engineering and Administrative Expenses

Selling, engineering and administrative expenses increased 6.5%, or $0.4 million, to $5.8 million compared to the same quarter last year. The change is primarily a result of increases in compensation and fringe benefit costs.

Interest Income, Net

Net interest income was $0.2 million for the quarter ended June 28, 2008, compared to $0.1 million for the quarter ended June 30, 2007. Total average debt for the quarter ended June 28, 2008, was $0.6 million compared to $0.9 million for the quarter ended June 30, 2007. Total average cash for the quarter ended June 28, 2008, was $25.7 million compared to $13.2 million for the quarter ended June 30, 2007. The Company did not have any outstanding variable debt during the period ended June 28, 2008.

Foreign Currency Transaction Loss, Net

There was a net foreign currency transaction loss of $0.1 million for the quarter ended June 28, 2008, compared to a minimal loss for the quarter ended June 30, 2007. The loss is primarily related to the strengthening of the US Dollar against the Korean Won.

Miscellaneous (Income)/Expense, Net

There was a minimal net miscellaneous expense for the quarter ended June 28, 2008, compared to net miscellaneous income of $0.1 for the quarter ended June 30, 2007. Net miscellaneous (income)/expense is primarily the result of earnings from joint ventures.

Income Taxes

The provision for income taxes for the quarter ended June 28, 2008, was 33.2% of pretax income compared to 34.2% for the quarter ended June 30, 2007. The change was primarily due to the relative levels of income and different tax rates in effect among the countries in which the Company sells its products and the decrease in the German Statutory tax rate.

COMPARISON OF THE SIX MONTHS ENDED JUNE 28, 2008 AND JUNE 30, 2007

Net Sales

Net sales were $100.6 million, an increase of $16.3 million, or 19.3%. This increase reflected strong demand in Europe and Asia, and continuous growth in the United States.

European sales increased 22.8%, or $6.3 million, to $33.9 million. Sales to Germany increased 23.8%, to the U.K. 18.3%, and to France 6.2%. Significant increases were also noted in Austria, Italy, Norway, and the Netherlands.

Asian sales increased 30.9%, or $4.6 million, to $19.5 million. Domestic sales in Korea increased 11.0%, sales to China increased 167.5%, and sales to Japan increased 10.1%.

North American sales increased 12.3%, or $4.9 million, to $44.8 million.

Gross Profit

Gross profit increased 28.4%, or $8.0 million. Gross profit as a percentage of net sales increased to 36.0% from 33.4% last year. Increases in gross profit were primarily due to fixed cost absorption from higher sales volume, productivity improvements in the U.S., lower material costs in the German operation due to the strength of local currencies against the U.S. dollar for material purchases made in U.S. dollars, and a price increase that occurred in January 2008. Improvements were partially offset by increases in pension expense related to an additional ESOP contribution and group health insurance.

Selling, Engineering, and Administrative Expenses

Selling, engineering and administrative expenses increased 10.3%, or $1.1 million, to $11.7 million compared to last year. The change is primarily a result of increases in compensation and fringe benefit costs, including pension expense and group health insurance.

Interest Income, Net

Net interest income for the six months ended June 28, 2008, was $0.3 million compared to $0.2 for the six months ended June 30, 2007. Total average debt for the period ended June 28, 2008, was $0.6 million compared to $1.0 million for the period ended June 30, 2007. Total average cash for the period ended June 28, 2008, was $23.7 million compared to $11.6 million for the period ended June 30, 2007. The Company did not have any outstanding variable debt during the period ended June 28, 2008.

Foreign Currency Transaction Loss, Net

There was a net foreign currency transaction loss of $0.1 million for the six months ended June 28, 2008, compared to a minimal impact from foreign currency transactions during the six months ended June 30, 2007. The loss is primarily related to the Korean operation, resulting from the strengthening of the US Dollar against the Korean Won.

Miscellaneous Income, Net

Miscellaneous income was $0.2 for the six months ended June 28, 2008, and June 30, 2007. The current year income was primarily a result of proceeds from an insurance claim and equity earnings. These amounts were partially offset by a loss on disposal of assets.

Income Taxes

The provision for income taxes for the six months ended June 28, 2008, was 33.1% of pretax income compared to 34.3% for the six months ended June 30, 2007. The change was primarily due to the relative levels of income and different tax rates in effect among the countries in which the Company sells its products and the decrease in the German Statutory tax rate.

LIQUIDITY AND CAPITAL RESOURCES

Historically, the Company's primary source of capital has been cash generated from operations, although fluctuations in working capital requirements have from time to time been met through borrowings under revolving lines of credit. The Company's principal uses of cash have been to pay operating expenses, make capital expenditures, pay dividends to shareholders, repurchase Company common stock and service debt.

Cash from operations for the six months ended June 28, 2008, was $20.1 million, compared to $12.5 million for the six months ended June 30, 2007. The $7.7 million increase in the Company's net cash flow from operations during the period was due primarily to the increase in net income, offset by changes in working capital. Increased accrued expenses and a smaller increase in other current assets added to operational cash flows. These amounts were partially offset by the increase in accounts receivable. Days sales outstanding (DSO) were 39 and 37 at June 28, 2008, and June 30, 2007, respectively. The increase in DSO is partially a result of increasing international demand, where customary payment terms are generally longer than with domestic customers. Inventory turns increased to 10.6 as of June 28, 2008, compared to 10.5 as of June 30, 2007.

Capital expenditures, consisting primarily of purchases of machinery and equipment, were $4.4 million for the six months ended June 28, 2008, compared to $6.9 million for the six months ended June 30, 2007. Also included in capital expenditures for the six months ended June 28, 2008, is the purchase of land for $2.5 million. Capital expenditures for the year are projected to be approximately $12.0 million.

The Company declared a discretionary cash dividend of $0.09 per share to shareholders of record as of May 15, 2008, payable on May 30, 2008. The Company also declared a quarterly dividend of $0.09 per share to shareholders of record as of June 30, 2008, payable on July 15, 2008. The declaration and payment of future dividends is subject to the sole discretion of the Board of Directors, and any determination as to the payment of future dividends will depend upon the Company's profitability, financial condition, capital needs, future prospects and other factors deemed pertinent by the Board of Directors.

The Company believes that cash generated from operations and its borrowing availability under its revolving Line of Credit will be sufficient to satisfy the Company's operating expenses and capital expenditures for the foreseeable future. In the event that economic conditions were to severely worsen for

a protracted period of time, the Company would have several options available to ensure liquidity in addition to increased borrowing. Capital expenditures could be postponed since they primarily pertain to long-term improvements in operations. Additional operating expense reductions also could be made. Finally, the dividend to shareholders could be reduced or suspended.

Off Balance Sheet Arrangements

The Company uses the equity method of accounting to account for its investments in Sun China, WhiteOak and High Country Tek. The Company does not have a majority ownership in or exercise control over any of these entities. The Company does not believe that its investments in Sun China, WhiteOak, or High Country Tek qualify as Variable Interest Entities, within the scope of FASB Interpretation (FIN) No. 46(R), Consolidation of Variable Interest Entities (revised December 2003), an interpretation of ARB No. 51, nor are they material to the financial statements of the Company at June 28, 2008.

Seasonality

The Company generally has experienced increased sales during the second quarter of the year, largely as a result of the order patterns of our customers. As a result, the Company's second quarter net sales, income from operations and net income historically are the highest of any quarter during the year.

Inflation

The impact of inflation on the Company's operating results has been moderate in recent years. While inflation has not had, and the Company does not expect that it will have, a material impact upon operating results, there is no assurance that the Company's business will not be affected by inflation in the future.

Critical Accounting Policies and Estimates

The Company currently applies judgment and estimates which may have a material effect on the eventual outcome of assets, liabilities, revenues and expenses for impairment of long-lived assets, accounts receivable, inventory, goodwill and accruals. The following explains the basis and the procedure for each account where judgment and estimates are applied.

Revenue Recognition

The Company reports revenues, net of sales incentives, when title passes and risk of loss transfers to the customer. The effect of material non-recurring events is provided for when they become known.

Impairment of Long-Lived Assets

In accordance with Statement of Financial Accounting Standards ("FAS") No. 144, Accounting for Impairment or Disposal of Long-lived Assets ("FAS 144"), long-lived assets, such as property and equipment, and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of the asset is measured by comparison of its carrying amount to future net cash flows the asset is expected to generate. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the asset exceeds its fair market value.

The Company assesses the recoverability of goodwill and intangible assets not subject to amortization under FAS No. 142, Goodwill and Other Intangible Assets ("FAS 142"). See Goodwill below.

Accounts Receivable

The Company sells to most of its customers on a recurring basis, primarily through distributors with which

the Company maintains long-term relationships. As a result, bad debt experience has not been material. The allowance for doubtful accounts is determined on a specific identification basis by a review of those accounts that are significantly in arrears. There can be no assurance that a distributor or a large direct sale customer with overdue accounts receivable balances will not develop financial difficulties and default on payment. See balance sheet for allowance amounts.

Inventory

The Company offers a wide variety of standard products and as a matter of policy does not discontinue products. On an ongoing basis, component parts found to be obsolete through design or process changes are disposed of and charged to material cost. The Company reviews on-hand balances of products and component parts against specific criteria. Products and component parts without usage or that have excess quantities on hand are evaluated. An inventory reserve is then established for the full inventory carrying value of those products and component parts deemed to be obsolete or slow moving. See Note 5 for inventory reserve amounts.

Goodwill

The Company acquired its Korean operations in September 1998 using the purchase method. As a result, goodwill is reflected on the consolidated balance sheet. A valuation based on the cash flow method was performed at December 29, 2007. It was determined that the value of the goodwill was not impaired. There is no assurance that the value of the acquired company will not decrease in the future due to changing business conditions. See Note 6 for goodwill amounts.

Accruals

The Company makes estimates related to certain employee benefits and miscellaneous accruals. Estimates for employee benefit accruals are based on information received from plan administrators in conjunction with management's assessments of estimated liabilities related to workers' compensation, health care benefits and annual contributions to an employee stock ownership plan, established in 2004 as part of the Company's retirement plan. Estimates for miscellaneous accruals are based on management's assessment of estimated liabilities for costs incurred.
