RISK FACTORS

Investing in our common stock involves a high degree of risk. You should carefully consider the following risk factors, as well as the other information in this prospectus, before deciding whether to invest in shares of our common stock. If any of the following risks actually occurs, our business, financial condition and results of operations would suffer. In this case, the trading price of our common stock would likely decline and you might lose all or part of your investment in our common stock. Additional risks that we currently do not know about or that we currently believe to be immaterial may also impair our business operations.

Risks Related to Our Business and Industry

Our recent significant growth makes it difficult to evaluate our current business and future prospects and may increase the risk of your investment.

Although we have been operating since 1993, our revenues have grown substantially in recent periods, which makes it difficult to evaluate our current business and future prospects. You must consider our business and prospects in light of the risks and difficulties we encounter as a rapidly growing technology company in a very competitive market. These risks and difficulties include, but are not limited to, the risks identified in this section and in particular the following factors:

We may not be able to successfully address any of these risks or others. Failure to do so adequately could seriously harm our business and cause our operating results to suffer.

Our quarterly operating results will likely fluctuate in the future, which could cause rapid declines in our stock price.

As our business continues to grow, we believe that our quarterly operating results will be subject to greater fluctuation due to various factors, many of which are beyond our control. Factors that may affect quarterly operating results in the future include:

Table of Contents

Accordingly, it is difficult for us to accurately forecast our growth and results of operations on a quarterly basis. If we fail to meet expectations of investors or analysts, our stock price may fall rapidly and without notice. Furthermore, the fluctuation of quarterly operating results may render less meaningful period-to-period comparisons of our operating results, and you should not rely upon them as an indication of future performance.

If the demand for application optimized server solutions does not continue to develop as we anticipate, demand for our server solutions may not grow as we expect.

The success of our business depends on businesses continuing to choose application optimized server solutions for running their critical business applications. The market for application optimized server solutions has a short history marked by frequent introductions of new technologies and products. Many of these technologies and products have not yet gained, and may not gain, significant customer acceptance. We expect to devote significant resources to identifying new market trends and developing products to meet anticipated customer demand for application optimized server solutions. Ultimately, however, customers may not purchase application optimized server solutions and instead select general purpose lower-cost servers and components. We are also part of a broader market for server solutions and demand for these server solutions may decline or fail to grow as we expect. Accordingly, we can not assure you that demand for the type of server solutions we offer and plan to offer will continue to develop as we anticipate, or at all.

Our future financial performance will depend on the timely introduction and widespread acceptance of new server solutions and increased functionality of our existing server solutions.

Our future financial performance will depend on our ability to meet customer specifications and requirements by enhancing our current server solutions and developing server solutions with new and better functionality. For example, we are spending a material portion of our research and development budget on the development of blade server systems, which we expect to introduce during the first half of calendar 2007. The success of new features and new server solutions depends on several factors, including their timely introduction and market acceptance. We may not be successful in developing enhancements or new server solutions, or in timely bringing them to market. Customers may also defer purchases of our existing products pending the introduction of anticipated new products. If our new server solutions are not competitive with solutions offered by other vendors, we may not be perceived as a technology leader and could miss market opportunities. If we are unable to enhance the functionality of our server solutions or introduce new server solutions which achieve widespread market acceptance, our reputation will be damaged, the value of our brand will diminish, and our business will suffer. In addition, uncertainties about the timing and nature of new features and products could result in increases in our research and development expenses with no assurance of future sales.

We may not be able to successfully manage our planned growth and expansion.

We are pursuing new customers and expanding our product offerings to grow our business rapidly. In connection with this growth, we expect that our annual operating expenses will increase significantly during the

7

Table of Contents

foreseeable future as we invest in sales and marketing, research and development, manufacturing and production infrastructure, and strengthen customer service and support resources for our customers. Our failure to expand operational and financial systems timely or efficiently could result in additional operating inefficiencies, which could increase our costs and expenses more than we had planned and prevent us from successfully executing our business plan. We may not be able to offset the costs of operation expansion by leveraging the economies of scale from our growth in negotiations with our suppliers and contract manufacturers. Additionally, if we do increase our operating expenses in anticipation of the growth of our business and this growth does not meet our expectations, our financial results will be negatively impacted.

If our business grows, we will have to manage additional product design projects, materials procurement processes, and sales efforts and marketing for an increasing number of SKUs, as well as expand the number and scope of our relationships with suppliers, distributors and end customers. If we fail to manage these additional responsibilities and relationships successfully, we may incur significant costs, which may negatively impact our operating results.

Additionally, in our efforts to be first to market with new products with innovative functionality and features, we may devote significant research and development resources to products and product features for which a market does not develop quickly, or at all. If we are not able to predict market trends accurately, we may not benefit from such research and development activities, and our results of operations may suffer.

The market in which we participate is highly competitive, and if we do not compete effectively, we may not be able to increase our market penetration, grow our net sales or improve our gross margins.

The market for server solutions is intensely competitive and rapidly changing. Barriers to entry in our market are relatively low and we expect increased challenges from existing as well as new competitors. Some of our principal competitors offer server solutions at a lower price, which has resulted in pricing pressures on sales of our server solutions. We expect further downward pricing pressure from our competitors and expect that we will have to price some of our server solutions aggressively to increase our market share with respect to those products. If we are unable to maintain the margins on our server solutions, our operating results could be negatively impacted. In addition, if we do not develop new innovative server solutions, or enhance the reliability, performance, efficiency and other features of our existing server solutions, our customers may turn to our competitors for alternatives. In addition, pricing pressures and increased competition generally may also result in reduced sales, lower margins or the failure of our products to achieve or maintain widespread market acceptance, any of which could have a material adverse effect on our business, results of operations and financial condition.

Our principal competitors include global technology companies such as Dell, Inc., Hewlett-Packard Company, International Business Machines Corporation and Intel. In addition, we also compete with a number of smaller vendors who sell specialized servers, such as Rackable Systems, Inc., and original design manufacturers, or ODMs, such as Quanta Computer Incorporated.

Many of our competitors enjoy substantial competitive advantages, such as:

8

Table of Contents

As a result, our competitors may be able to respond more quickly and effectively than we can to new or changing opportunities, technologies, standards or customer requirements. Furthermore, because of these advantages, even if our application optimized server solutions are more effective than the products that our competitors offer, potential customers might accept competitive products in lieu of purchasing our products. The challenges we face from larger competitors will become even greater if consolidation or collaboration between or among our competitors occurs in our industry. For all of these reasons, we may not be able to compete successfully against our current or future competitors, and if we do not compete effectively, our ability to increase our net sales may be impaired.

Our sales cycle is lengthy and expensive, and could adversely affect the amount, timing and predictability of future net sales.

Our end customers generally need three to six months after an initial contact to make a final purchase decision with respect to our products. As customers weigh their purchase options, we may expend significant resources in pursuit of a sale that may ultimately fail to close. We have little control over our customers’ budget cycles and approval processes, or the strength of competitors’ relationships with our potential customers, all of which could adversely affect our sales efforts. The introduction of new products and product enhancements may lengthen our sales cycle as customers defer a decision on purchasing existing products and evaluate our new products. If we are unsuccessful in closing sales after expending significant resources, our net sales and operating expenses will be adversely affected.

As we increasingly target larger customers, our customer base may become less diversified, our cost of sales may increase, and our sales may be less predictable.

We expect that selling our server solutions to larger customers will create new challenges. No one customer represented 10% or more of our revenues for fiscal years 2005 or 2006. However, if certain customers buy our products in greater volumes, and their business becomes a larger percentage of our net sales, we may grow increasingly dependent on those customers to maintain our growth. If our largest customers do not purchase our products at the levels or in the timeframes that we expect, our ability to maintain or grow our net sales will be adversely affected.

Additionally, as we and our distribution partners focus increasingly on selling to larger customers and attracting larger orders, we expect greater costs of sales. Our sales cycle may become longer and more expensive, as larger customers typically spend more time negotiating contracts than smaller customers. In addition, larger customers often seek to gain greater pricing concessions, as well as greater levels of support in the implementation and use of our server solutions. These factors can result in lower margins for our products.

Increased sales to larger companies may also cause fluctuations in results of operations. A larger customer may seek to fulfill all or substantially all of its requirements in a single order, and not make another purchase for a significant period of time. Accordingly, a significant increase in revenue during the period in which we recognize the revenue from the sale may be followed by a period of time during which the customer purchases none or few of our products. A significant decline in net sales in periods following a significant order could adversely affect our stock price.

We must work closely with our suppliers to make timely new product introductions.

We rely on our close working relationships with our suppliers, including Intel and AMD, to anticipate and deliver new products on a timely basis when new generation materials and core components are made available. If we are not able to maintain our relationships with our suppliers or continue to leverage their research and development capabilities to develop new technologies desired by our customers, our ability to quickly offer advanced technology and product innovations to our customers would be impaired.

Table of Contents

Our suppliers’ failure to improve the functionality and performance of materials and core components for our products may impair or delay our ability to deliver innovative products to our customers.

We need our material and core component suppliers, such as Intel and AMD, to provide us with core components that are innovative, reliable and attractive to our customers. Due to the pace of innovation in our industry, many of our customers may delay or reduce purchase decisions until they believe that they are receiving best of breed products that will not be rendered obsolete by an impending technological development. Accordingly, demand for new server systems that incorporate new products and features is significantly impacted by our suppliers’ new product introduction schedules and the functionality, performance and reliability of those new products. If our materials and core component suppliers fail to deliver new and improved materials and core components for our products, we may not be able to satisfy customer demand for our products in a timely manner, or at all. If our suppliers’ components do not function properly, we may incur additional costs and our relationships with our customers may be adversely affected.

As our business grows, we expect that we may be exposed to greater customer credit risks.

Historically, we have offered limited credit terms to our customers. As our customer base expands, as our orders increase in size, and as we obtain more direct customers, we expect to offer increased credit terms and flexible payment programs to our customers. Doing so may subject us to increased credit risk, higher accounts receivable with larger days outstanding, and increases in charges or reserves, which could have a material adverse effect on our business, results of operations and financial condition.

Our ability to develop our brand is critical to our ability to grow.

We believe that acceptance of our server solutions by an expanding customer base depends in large part on increasing awareness of the Supermicro brand and that brand recognition will be even more important as competition in our market develops. In particular, we expect an increasing proportion of our sales to come from sales of server systems, the sales of which we believe may be particularly impacted by brand strength. Successful promotion of our brand will depend largely on the effectiveness of our marketing efforts and on our ability to develop reliable and useful products at competitive prices. To date, we have not devoted significant resources to building our brand, and have limited experience in increasing customer awareness of our brand. Our future brand promotion activities, including any expansion of our cooperative marketing programs with strategic partners, may involve significant expense and may not generate desired levels of increased revenue, and even if such activities generate some increased revenue, such increased revenue may not offset the expenses we incurred in endeavoring to build our brand. If we fail to successfully promote and maintain our brand, or incur substantial expenses in our attempts to promote and maintain our brand, we may fail to attract enough new customers or retain our existing customers to the extent necessary to realize a sufficient return on our brand-building efforts, and as a result our operating results and financial condition could suffer.

We principally rely on indirect sales channels for the sale and distribution of our products and any disruption in these channels could adversely affect our sales.

Historically, a substantial majority of our revenues have resulted from sales of our server solutions through third party distributors and resellers. We depend on our distributors to assist us in promoting market acceptance of our products and anticipate that a majority of our revenues will continue to result from sales through indirect channels. To maintain and potentially increase our revenue and profitability, we will have to successfully preserve and expand our existing distribution relationships as well as develop new distribution relationships. Our distributors also sell products offered by our competitors and may elect to focus their efforts on these sales. If our competitors offer our distributors more favorable terms or have more products available to meet the needs of their customers, or utilize the leverage of broader product lines sold through the distributors, those distributors may de-emphasize or decline to carry our products. In addition, our distributors’ order decision-making process is complex and involves several factors, including end customer demand, warehouse allocation and marketing resources, which can make it difficult to accurately predict total sales for the quarter until late in the quarter. We also do not control the pricing or discounts offered by distributors to end customers. To maintain our

10

Table of Contents

participation in distributors’ marketing programs, in the past we have provided promotional goods or made short-term pricing concessions. The discontinuation of promotional goods or pricing concessions could have a negative effect on our business. Our distributors could also modify their business practices, such as payment terms, inventory levels or order patterns. If we are unable to maintain successful relationships with distributors or expand our distribution channels or we experience unexpected changes in payment terms, inventory levels or other practices by our distributors, our business will suffer.

We may be unable to accurately predict future sales through our distributors, which could harm our ability to efficiently manage our resources to match market demand.

Since a significant portion of our sales are made through domestic and international distributors, our financial results, quarterly product sales, trends and comparisons are affected by fluctuations in the buying patterns of end customers and our distributors, and by the changes in inventory levels of our products held by these distributors. We generally record revenue based upon a “sell-in” model. While we attempt to assist our distributors in maintaining targeted stocking level of our products, we may not consistently be accurate or successful. This process involves the exercise of judgment and use of assumptions as to future uncertainties including end customer demand. Our distributors also have various rights to return products which could, among other things, result in our having to repurchase inventory which has declined in value or is obsolete. Consequently, actual results could differ from our estimates. Inventory levels of our products held by our distributors may exceed or fall below the levels we consider desirable on a going-forward basis. This could adversely affect our distributors or our ability to efficiently manage or invest in internal resources, such as manufacturing and shipping capacity, to meet the demand for our products.

If we are required to change the timing of our revenue recognition, our net sales and net income could decrease.

We currently record revenue based upon a “sell-in” model with revenues generally recorded upon shipment of products to our distributors. This requires that we maintain a reserve to cover the estimated costs of any returns or exercises of stock rotation rights, which we estimate primarily based on our historical experience. If facts and circumstances change such that the rate of returns of our products exceeds our historical experience, we may have to increase our reserve, which, in turn, would cause our revenue to decline. Similarly, if facts and circumstances change such that we are no longer able to determine reasonable estimates of our sales returns, we would be required to defer our revenue recognition until the point of sale from the distributors to their customers. Any such change may negatively impact our net sales or net income for particular periods and cause a decline in our stock price.

The average selling prices for our existing server solutions have declined and are likely to continue to decline, which could harm our results of operations.

As with most electronics based products, average selling prices of our server solutions typically are highest at the time of introduction of new products, which utilize the latest technology, and tend to decrease over time as such products become commoditized and are ultimately replaced by even newer generation products. The average selling prices of our existing server solutions have declined, and, consistent with industry trends, we anticipate that they will continue to decline. We cannot predict the timing or amount of any decline in the average selling prices of our server solutions. In some instances, our agreements with our distributors limit our ability to reduce prices unless we make such price reductions available to them, or price protect their inventory. If we are unable to decrease per unit manufacturing costs faster than the rate at which average selling prices continue to decline, our business, financial condition and results of operations will be harmed.

Our cost structure and ability to deliver server solutions to customers in a timely manner may be adversely affected by volatility of the market for core components and materials for our products.

Prices of materials and core components utilized in the manufacture of our server solutions, such as serverboards, chassis and central processing units, or CPUs, represent a significant portion of our cost of sales.

11

Table of Contents

We generally do not enter into long-term supply contracts for these materials and core components, but instead purchase these materials and components on a purchase order basis. Prices of these core components and materials are volatile, and, as a result, it is difficult to predict expense levels and operating results. In addition, if our business growth renders it necessary or appropriate to transition to longer term contracts with materials and core component suppliers, our costs may increase and our gross margins could correspondingly decrease.

Because we often acquire materials and core components on an as needed basis, we may be limited in our ability to effectively and efficiently respond to customer orders because of the then-current availability or the terms and pricing of materials and core components. Our industry has experienced materials shortages and delivery delays in the past, and we may experience shortages or delays of critical materials in the future. From time to time, we have been forced to delay the introduction of certain of our products or the fulfillment of customer orders as a result of shortages of materials and core components. If shortages or delays arise, the prices of these materials and core components may increase or the materials and core components may not be available at all. In addition, in the event of shortages, some of our larger competitors may have greater abilities to obtain materials and core components due to their larger purchasing power. We may not be able to secure enough core components or materials at reasonable prices or of acceptable quality to build new products to meet customer demand, which could adversely affect our business and financial results.

We may lose sales or incur unexpected expenses relating to insufficient, excess or obsolete inventory.

As a result of our strategy to provide greater choice and customization of our products to our customers, we are required to maintain a high level of inventory. If we fail to maintain sufficient inventory, we may not be able to meet demand for our products on a timely basis, and our sales may suffer. If we overestimate customer demand for our products, we could experience excess inventory of our products and be unable to sell those products at a reasonable price, or at all. Additionally, the rapid pace of innovation in our industry could render significant portions of our existing inventory obsolete. Server systems and components that have been customized and later returned by those of our customers and partners who have return rights or stock rotation rights may be unusable for other purposes or may require reformation at additional cost to be made ready for sale to other customers. Excess or obsolete inventory levels for these or other reasons could result in unexpected expenses or increases in our reserves against potential future charges which would adversely affect our business and financial results. During fiscal years 2004, 2005 and 2006, we recorded inventory write-downs charged to cost of sales of $1.9 million, $0.6 million and $1.0 million, respectively, for excess and obsolete inventory.

Our focus on internal development and customizable server solutions could delay our introduction of new products and result in increased costs.

Our strategy is to rely to a significant degree on internally developed components, even when third party components may be available. We believe this allows us to develop products with a greater range of features and functionality and allows us to develop solutions that are more customized to customer needs. However, if not properly managed, this reliance on internally developed components may be more costly than use of third party components, thereby making our products less price competitive or reducing our margins. In addition, our reliance on internal development may lead to delays in the introduction of new products and impair our ability to introduce products rapidly to market. We may also experience increases in our inventory costs and obsolete inventory, thereby reducing our margins.

Our research and development expenditures, as a percentage of our total revenues, are considerably higher than many of our competitors and our earnings will depend upon maintaining revenues and margins that offset these expenditures.

Our strategy is to focus on being consistently rapid-to-market with flexible and customizable server systems that take advantage of our own internal development and the latest technologies offered by microprocessor manufacturers and other component vendors. Consistent with this strategy, we spend higher amounts, as a percentage of revenues, on research and development costs than many of our competitors. If we can not sell our

12

Table of Contents

products in sufficient volume and with adequate gross margins to compensate for such investment in research and development, our earnings may be materially and adversely affected.

If our limited number of contract manufacturers or suppliers of materials and core components fail to meet our requirements, we may be unable to meet customer demand for our products, which could decrease our revenues and earnings.

We purchase many sophisticated materials and core components from one or a limited number of qualified suppliers and rely on a limited number of contract manufacturers to provide value added design, manufacturing, assembly and test services. We generally do not have long-term agreements with these vendors, and instead obtain key materials and services through purchase order arrangements. We have no contractual assurances from any contract manufacturer that adequate capacity will be available to us to meet future demand for our products.

Consequently, we are vulnerable to any disruptions in supply with respect to the materials and core components provided by limited-source suppliers, and we are at risk of being harmed by discontinuations of design, manufacturing, assembly or testing services from our contract manufacturers. We have occasionally experienced delivery delays from our suppliers and contract manufacturers because of high industry demand or because of inability to meet our quality or delivery requirements. Occasionally, vendors may go out of business or may cease providing materials, core components or services to us. If our relationships with our suppliers and contract manufactures are negatively impacted by late payments or other issues, we may not receive timely delivery of materials and core components. If we were to lose any of our current supply or contract manufacturing relationships, the process of identifying and qualifying a new supplier or contract manufacturer who will meet our quality and delivery requirements, and who will appropriately safeguard our intellectual property, may require a significant investment of time and resources, adversely affecting our ability to satisfy customer purchase orders and delaying our ability to rapidly introduce new products to market. Similarly, if any of our suppliers were to cancel or materially change contracts or commitments to us or fail to meet the quality or delivery requirements needed to satisfy customer demand for our products, our reputation and relationships with customers could be damaged. We could lose orders, be unable to develop or sell some products cost-effectively or on a timely basis, if at all, and have significantly decreased revenues, margins and earnings, which would have a material adverse effect on our business.

Our failure to deliver high quality server solutions could damage our reputation and diminish demand for our products.

Our server solutions are critical to our customers’ business operations. Our customers require our server solutions to perform at a high level, contain valuable features and be extremely reliable. The design of our server solutions is sophisticated and complex, and the process for manufacturing, assembling and testing our server solutions is challenging. Occasionally, our design or manufacturing processes may fail to deliver products of the quality that our customers require. For example, in 2000, a vendor provided us with a defective capacitor that failed under certain heavy use applications. As a result, our product needed to be repaired. Though the vendor agreed to pay for a large percentage of the costs of the repairs, we incurred costs in connection with the recall and diverted resources from other projects.

New flaws or limitations in our server solutions may be detected in the future. Part of our strategy is to bring new products to market quickly, and first-generation products may have a higher likelihood of containing undetected flaws. If our customers discover defects or other performance problems with our products, our customers’ businesses, and our reputation, may be damaged. Customers may elect to delay or withhold payment for defective or underperforming server solutions, request remedial action, terminate contracts for untimely delivery, or elect not to order additional server solutions. Additionally, customers may make warranty claims against us, which could result in an increase in our provision for doubtful accounts, an increase in collection cycles for accounts receivable or subject us to the expense and risk of litigation. We may incur expense in recalling, refurbishing or repairing defective server solutions. If we do not properly address customer concerns about our products, our reputation and relationships with our customers may be harmed. For all of these reasons,

13

Table of Contents

customer dissatisfaction with the quality of our products could substantially impair our ability to grow our business.

Conflicts of interest may arise between us and Ablecom Technology Inc., Adaptec, Inc. or Tatung Company, three of our major contract manufacturers, and those conflicts may adversely affect our operations.

We use Ablecom Technology, a related party, for contract design and manufacturing coordination support. We work with Ablecom to optimize modular designs for our chassis and certain of other components. In fiscal year 2006, we purchased products from Ablecom in the aggregate amount of approximately $75.7 million.

Steve Liang, Ablecom’s Chief Executive Officer and largest shareholder, is the brother of Charles Liang, our President, Chief Executive Officer and Chairman of the Board. Charles Liang, and his spouse, Chiu-Chu (Sara) Liu Liang, our Vice President of Operations, Treasurer and director, jointly own approximately 30.7% of Ablecom’s outstanding common stock. Charles Liang served as a director of Ablecom during our fiscal 2006, but is not currently serving in such capacity. In addition, Yih-Shyan (Wally) Liaw and his wife jointly own approximately 5.2% of Ablecom’s outstanding common stock, and collectively, Mr. Charles Liang, Ms. Liang, Mr. Liaw, Mr. Steve Liang and relatives of these individuals own over 80% of Ablecom’s outstanding common stock. Mr. and Mrs. Liang, as directors, officers and significant stockholders, and Mr. Liaw, as an officer, director and significant stockholder, of the Company, have considerable influence over the management of our business relationships. Accordingly, we may be disadvantaged by their economic interests as stockholders of Ablecom and their personal relationship with Ablecom’s Chief Executive Officer. We may not negotiate or enforce contractual terms as aggressively with Ablecom as we might with an unrelated party, and the commercial terms of our agreements may be less favorable than we might obtain in negotiations with third parties. If our business dealings with Ablecom are not as favorable to us as arms-length transactions, our results of operations may be harmed. Historically, transactions with Ablecom were not approved by an independent committee of our board of directors as we had no independent directors.

We use Tatung Company for contract manufacturing services. Tatung also purchases our server systems and components. Similarly, we purchase Adaptec drivers that are developed and configured for us, and concurrently sell our products to Adaptec. In fiscal year 2006, we purchased contract manufacturing services and products, respectively, from Tatung and Adaptec in the aggregate amount of approximately $14.4 million and $6.3 million, respectively, and sold products to Tatung and Adaptec in the aggregate amount of approximately $0.1 million and $3.5 million, respectively. Since Tatung and Adaptec are both customers and vendors, the terms and conditions of our business agreements with them may not be as favorable, individually or in aggregate, as we may be able to receive from unrelated third parties, and we may not as strongly enforce our rights under these agreements. In addition, if a dispute were to arise under our agreement to sell our products to Tatung or Adaptec, the dispute could lead to disruption or termination of the provision of services or products by them to us. This could compromise our ability to satisfy customer orders on a timely basis, if at all, or we may incur significant costs in establishing an agreement with a new vendor, the terms of which may not be as favorable as those in our agreements with Tatung and Adaptec. In that event, our revenues, margins and earnings could suffer. At the same time, if a dispute were to arise under our agreement to purchase contract manufacturing services or products from Tatung or Adaptec, the dispute may cause them to reduce or terminate their purchases of our products, thereby reducing our revenues.

In addition, our relationships with Ablecom and Tatung, who are stockholders as well as providers of contract manufacturing services, could be adversely affected by declines in our stock price or divestments by Ablecom or Tatung of their shares of our common stock. Steve Liang, Ablecom’s Chief Executive Officer, and Tatung held approximately 4.5% and 9.0%, respectively, of our outstanding common stock prior to the completion of this offering. If the value of the shares that Steve Liang or Tatung holds should decline, by decrease in our stock price or by disposition of the shares, Ablecom, because Steve Liang has considerable influence over Ablecom’s commercial agreements, or Tatung may not be willing to give us terms and conditions for contract manufacturing services that are as favorable as those in our existing contracts. Likewise, if Steve Liang ceases to have significant influence over Ablecom, or if those of our stockholders who hold shares of Ablecom cease to hold a majority of the outstanding shares of Ablecom, the terms and conditions of our

14

Table of Contents

agreements with Ablecom may not be as favorable as those in our existing contracts. As a result, our costs could increase and adversely affect our margins and results of operations.

For more information regarding our relationships with Ablecom and Tatung, see “Certain Relationships and Related Party Transactions.”

We are increasing our reliance on Ablecom and could be subject to risks associated with greater reliance on a limited source of contract manufacturing services and inventory warehousing.

We plan to expand our warehousing capacity and our manufacturing relationship with Ablecom in China. Ablecom is transferring operations from Taiwan to a larger facility in China. In addition to providing a larger volume of contract manufacturing services for us, Ablecom will warehouse for us an increasing number of components and subassemblies manufactured by multiple suppliers prior to shipment to our facilities in the U.S. and Europe. We also anticipate that we will continue to lease office space from Ablecom in Taiwan to support the research and development efforts we are undertaking.

If we or Ablecom fail to manage the transition of contract manufacturing services and warehouse operations to China, we may experience delays in our ability to fulfill customer orders. Similarly, if Ablecom’s facility in China is subject to damage, destruction or other disruptions, our inventory may be damaged or destroyed, and we may be unable to find adequate alternative providers of contract manufacturing services in the time that we or our customers require. We could lose orders and be unable to develop or sell some products cost-effectively or on a timely basis, if at all.

Currently, we purchase contract manufacturing services primarily for our chassis and power supply products from Ablecom. If our commercial relationship with Ablecom were to deteriorate or terminate, establishing direct relationships with those entities supplying Ablecom with key materials for our products or identifying and negotiating agreements with alternative providers of warehouse and contract manufacturing services might take a considerable amount of time and require a significant investment of resources. We may not be able to establish business arrangements that are, individually or in the aggregate, as favorable as the terms and conditions we have established with Ablecom. If any of these things should occur, our revenues, margins and earnings could significantly decrease, which would have a material adverse effect on our business.

We are increasing our operations in China and could be subject to risks of doing business in the region.

We intend to increase our business operations in Asia, and particularly in China. As a result, our exposure to the business risks presented by the economies and regulatory environments of Asia will increase. For example, the validity, enforceability and scope of protection of intellectual property is uncertain and evolving in China, and our intellectual property rights may not be protected under the laws of China to the same extent as under laws of the United States. If our intellectual property is misappropriated, we may experience unfair competition and declining sales or be forced to incur increased costs of enforcing our intellectual property rights, both of which would adversely affect our revenues, gross margins and results of operations.

Our growth into markets outside the United States exposes us to risks inherent in international business operations.

We market and sell our systems and components both domestically and outside the United States. We intend to expand our international sales efforts, especially into Asia, but our international expansion efforts may not be successful. Our international operations expose us to risks and challenges that we would otherwise not face if we conducted our business only in the United States, such as:

These factors could limit our future international sales or otherwise adversely impact our operations

We have recently entered into plea and settlement agreements with the government relating to violations of export control and economic sanctions laws that occurred during the 2001 to 2003 timeframe; if we fail to comply with laws and regulations restricting dealings with sanctioned countries, we may be subject to future civil or criminal penalties, which may have a material adverse effect on our business or ability to do business outside the U.S.

In 2004, we received subpoenas from the Bureau of Industry and Security of the Department of Commerce, or BIS, with respect to our relationship with a distributor and transactions involving the sale and resale of products to Iran that occurred prior to 2004. After receiving the first subpoena, we retained special export control counsel, conducted an internal investigation into these matters and terminated our relationship with the distributor in question. We also instituted a new export compliance program, which program we continue to develop and implement. The U.S. Department of Justice and Office of Foreign Assets Control of the Department of Treasury, or OFAC, also initiated investigations regarding these matters.

In September 2006, we entered into an agreement with the U.S. Department of Justice pursuant to which we agreed to plead guilty to one count of violating federal export regulations by shipping 300 motherboards to Dubai, UAE, with knowledge that they would be transshipped to Iran. We agreed to pay a $150,000 fine. The plea agreement has been approved by the U.S. District Court. We have also entered into a settlement agreement with BIS with respect to alleged violations of the Export Administration Regulations pursuant to which we agreed to pay a fine of approximately $125,000. We were charged by BIS with twelve violations of the Export Administration Regulations. Six of these violations involved the shipment of server systems and components without required government authorization through a distributor to end customers in Iran. Three of these violations involved allegations that shipments took place when we knew or had reason to know that the transactions would constitute a violation of the applicable regulations. Three involved claims that we made false declarations on shipping documents, stating that no license was required for the export of the products when in fact a government license was required. BIS has also issued a proposed charging letter to one of our employees who served as an international sales team leader at the time of the transactions in question. This individual continues to be employed by us; however, the individual no longer works in an international sales function. Potential civil charges against this employee have not been resolved by our settlement with BIS. Finally, we have signed a settlement agreement presented to us by OFAC relating to 21 alleged violations of U.S. sanctions laws and are awaiting a signed copy from OFAC. Pursuant to this agreement, we have paid a fine of $179,000. With the finalization of these agreements, we believe that all issues with respect to the matters under investigation have been resolved.

If our export compliance program is not effective, or if we are subject to any future claims regarding violation of export control and economic sanctions laws, we could be subject to civil or criminal penalties, which could lead to a material fine or other sanctions, including loss of export privileges, that may have a material adverse effect on our business, financial condition, results of operation and future prospects. In addition, these plea and settlement agreements and any future violations could have an adverse impact on our ability to sell our products to U.S. federal, state and local government and related entities.

Any failure to protect our intellectual property rights, trade secrets and technical know-how, could impair our brand and our competitiveness.

Our ability to prevent competitors from gaining access to our technology is essential to our success. If we fail to protect our intellectual property rights adequately, we may lose an important advantage in the markets in which we compete. Trademark, patent, copyright and trade secret laws in the United States and other jurisdictions as well as our internal confidentiality procedures and contractual provisions are the core of our efforts to protect our proprietary technology and our brand. Our patents and other intellectual property rights may be challenged by others or invalidated through administrative process or litigation, and we may initiate claims or litigation against third parties for infringement of our proprietary rights. Such administrative proceedings and litigation are inherently uncertain and divert resources that could be put towards other business priorities. We may not be able to obtain a favorable outcome and may spend considerable resources in our efforts to defend and protect our intellectual property.

Furthermore, legal standards relating to the validity, enforceability and scope of protection of intellectual property rights are uncertain. Effective patent, trademark, copyright and trade secret protection may not be available to us in every country in which our products are available. The laws of some foreign countries may not be as protective of intellectual property rights as those in the United States, and mechanisms for enforcement of intellectual property rights may be inadequate.

Accordingly, despite our efforts, we may be unable to prevent third parties from infringing upon or misappropriating our intellectual property and using our technology for their competitive advantage. Any such infringement or misappropriation could have a material adverse effect on our business, results of operations and financial condition.

Resolution of claims that we have violated or may violate the intellectual property rights of others could require us to indemnify our customers, resellers or vendors, redesign our products, or pay significant royalties to third parties, and materially harm our business.

Our industry is marked by a large number of patents, copyrights, trade secrets and trademarks and by frequent litigation based on allegations of infringement or other violation of intellectual property rights. At any time, a third party may assert that our technology or products violates such party’s intellectual property rights. For example, we are presently subject to a lawsuit filed on September 2, 2005 by Rackable Systems, Inc. alleging that one of our product families infringes two United States patents that relate to computers with front mounted I/O connectors and back-to-back placement of rack mounted computers. In its complaint, Rackable seeks compensatory damages, treble damages for willful infringement, interest, attorneys’ fees and injunctive relief. On September 8, 2006, the parties presented a tutorial to the court summarizing the technology involved in the case, the nature of the inventions of the patents, and background prior art. A “Markman” hearing was held on October 4, 2006. We are vigorously defending the suit, and we are currently engaged in discovery on the matter. Successful intellectual property claims against us from Rackable or others could result in significant financial liability or prevent us from operating our business or portions of our business as we currently conduct it or as we may later conduct it. In addition, resolution of claims may require us to redesign our technology, to obtain licenses to use intellectual property belonging to third parties, which we may not be able to obtain on reasonable terms, to cease using the technology covered by those rights, and to indemnify our customers, resellers or vendors. Any claim, regardless of its merits, could be expensive and time consuming to defend against, and divert the attention of our technical and management resources.

If we lose Charles Liang, our President, Chief Executive Officer and Chairman, or any other key employee or are unable to attract additional key employees, we may not be able to implement our business strategy in a timely manner.

Our future success depends in large part upon the continued service of our executive management team and other key employees. In particular, Charles Liang, our President, Chief Executive Officer and Chairman of the

17

Table of Contents

Board, is critical to the overall management of our company as well as to the development of our culture and our strategic direction. Mr. Liang co-founded our company and has been our Chief Executive Officer since our inception. His experience in running our business and his personal involvement in key relationships with suppliers, customers and strategic partners are extremely valuable to our company. Additionally, we are particularly dependent on the continued service of our existing research and development personnel because of the complexity of our products and technologies. Our employment arrangements with our executives and employees do not require them to provide services to us for any specific length of time, and they can terminate their employment with us at any time, with or without notice, without penalty. The loss of services of any of these executives or of one or more other key members of our team could seriously harm our business.

To execute our growth plan, we must attract additional highly qualified personnel, including additional engineers and executive staff. Competition for qualified personnel is intense, especially in San Jose, where we are headquartered. We have experienced in the past and may continue to experience difficulty in hiring and retaining highly skilled employees with appropriate qualifications. In particular, we are currently working to add personnel in our finance, accounting and general administration departments, which have historically had limited budgets and staffing. If we are unable to attract and integrate additional key employees in a manner that enables us to scale our business and operations effectively, or if we do not maintain competitive compensation policies to retain our employees, our ability to operate effectively and efficiently could be limited.

Our board and management team have a limited history of working together and may not be able to execute our business plan.

Two members of our Board joined our Board in August 2006. Howard Hideshima, our Chief Financial Officer, joined the Company in May 2006. We have also recently filled a number of positions in our finance and accounting staff. Accordingly, key personnel in our finance and accounting team have only recently assumed the duties and responsibilities they are now performing. Our Board members and key employees have worked together for only a limited period of time and have a limited track record of executing our business plan as a team. In addition, our executives have limited experience conducting business as a public company and fulfilling the increased legal, administrative and accounting obligations associated with being a public company. Accordingly, it is difficult to predict whether our directors and senior executives, individually and collectively, will be effective in managing our operations.

Any failure to adequately expand our sales force will impede our growth.

Though we expect to continue to rely primarily on third party distributors to sell our server solutions, we expect that, over time, our direct sales force will grow. Competition for direct sales personnel with the advanced sales skills and technical knowledge we need is intense. Our ability to grow our revenue in the future will depend, in large part, on our success in recruiting, training, retaining and successfully managing sufficient qualified direct sales personnel. New hires require significant training and may take six months or longer before they reach full productivity. Our recent hires and planned hires may not become as productive as we would like, and we may be unable to hire sufficient numbers of qualified individuals in the future in the markets where we do business. If we are unable to hire and develop sufficient numbers of productive sales personnel, sales of our server solutions will suffer.

Our direct sales efforts may create confusion for our end customers and harm our relationships with our distributors and OEMs.

Though our direct sales efforts have historically been limited and focused on customers who typically do not buy from distributors or OEMs, we expect our direct sales force to grow as our business grows. As our direct sales force becomes larger, our direct sales efforts may lead to conflicts with our distributors and OEMs, who may view our direct sales efforts as undermining their efforts to sell our products. If a distributor or OEM deems our direct sales efforts to be inappropriate, the distributor or OEM may not effectively market our products, may emphasize alternative products from competitors, or may seek to terminate our business relationship. Disruptions

18

Table of Contents

in our distribution channels could cause our revenues to decrease or fail to grow as expected. Our failure to implement an effective direct sales strategy that maintains and expands our relationships with our distributors and OEMs could lead to a decline in sales and adversely affect our results of operations.

Backlog does not provide a substantial portion of our net sales in any quarter.

Our revenues are difficult to forecast because we do not have sufficient backlog of unfilled orders to meet our quarterly net sales targets at the beginning of a quarter. Rather, a majority of our net sales in any quarter depend upon customer orders that we receive and fulfill in that quarter. Because our expense levels are based in part on our expectations as to future net sales and to a large extent are fixed in the short term, we might be unable to adjust spending in time to compensate for any shortfall in net sales. Accordingly, any significant shortfall of revenues in relation to our expectations would harm our operating results.

If the market for modular, open standard-based products does not continue to grow, opportunities to sell our products will be scarcer and our ability to grow would suffer.

The success of our business requires companies to commit to a modular, open standard-based server architecture instead of traditional proprietary and RISC/UNIX based servers. If enterprises do not adopt this open standard-based approach, the market for our products may not grow as we anticipate and our revenues would be adversely affected. Many prospective customers have invested significant financial and human resources in their existing systems, many of which are critical to their operations, and they may be reticent to overhaul their systems. Moreover, many of the server systems that we sell currently run on the Linux operating system, and are subject to the GNU General Public License. Pending litigation involving Linux and the GNU General Public License could be resolved in a manner that adversely affects Linux adoption in our industry and could materially harm our ability to sell our products based on the Linux operating system and the GNU General Public License. If the market for open standard-based modular technologies does not continue to develop for any reason, our ability to grow our business will be adversely affected.

Market demand for our products may decrease as a result of changes in general economic conditions, as well as incidents of terrorism, war and other social and political instability.

Our revenues and gross profit depend largely on general economic conditions and, in particular, the strength of demand for our server solutions in the markets in which we are doing business. From time to time, customers and potential customers have elected not to make purchases of our products due to reduced budgets and uncertainty about the future, and, in the case of distributors, declining demand from their customers for their solutions in which they integrate our products. Similarly, from time to time, acts of terrorism, in particular in the United States, have had a negative impact on information technology spending. High fuel prices and turmoil in the Middle East and elsewhere have increased uncertainty in the United States and our other markets. Should the current conflicts in the Middle East and in other parts of the world suppress economic activity in the United States or globally, our customers may delay or reduce their purchases on information technology, which would result in lower demand for our products and adversely affect our results of operations.

If we acquire any companies or technologies in the future, they could prove difficult to integrate, disrupt our business, dilute stockholder value and adversely affect our operating results.

In the future, we may acquire or make investments in companies, assets or technologies that we believe are complementary or strategic. We have not made any acquisitions or investments to date, and therefore our ability as an organization to make acquisitions or investments is unproven. If we decide to make an acquisition or investment, we face numerous risks, including:

19

Table of Contents

If we proceed with an acquisition or investment, we may be required to use a considerable amount of our cash, including proceeds from this offering, or to finance the transaction through debt or equity securities offerings, which may decrease our financial liquidity or dilute our stockholders and affect the market price of our stock. As a result, if we fail to properly evaluate and execute acquisitions or investments, our business and prospects may be harmed.

Maintaining and improving our financial controls and complying with rules and regulations applicable to public companies may be a significant burden on our management team and require considerable expenditures of our resources.

As a public company, we will incur additional legal, accounting and other expenses that we do not incur as a private company. The Securities Exchange Act of 1934, or the Exchange Act, the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, and The Nasdaq Marketplace Rules, or Nasdaq rules, will apply to us as a public company. Compliance with these rules and regulations will necessitate significant increases in our legal and financial budgets and may also strain our personnel, systems and resources.

The Exchange Act requires, among other things, filing of annual, quarterly and current reports with respect to our business and financial condition. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. Satisfying these requirements involves a commitment of significant resources and management oversight. As a result of management’s efforts to comply with such requirements, other important business concerns may receive insufficient attention, which could have a material adverse effect on our business, financial condition and results of operations. Failure to meet certain of these regulatory requirements may also cause us to be delisted from the Nasdaq Global Market.

In addition, we are hiring and will continue to hire additional legal, accounting and financial staff with appropriate public company experience and technical accounting knowledge, which will increase our operating expenses in future periods.

We also expect these rules and regulations to make it more difficult and more expensive for us to obtain director and officer liability insurance and we may be required to accept reduced coverage or incur substantially higher costs to maintain coverage. If we are unable to maintain adequate directors’ and officers’ insurance, it may be more difficult for us to attract and retain qualified persons to serve on our board of directors or as executive officers.

Our operations involve the use of hazardous and toxic materials, and we must comply with environmental laws and regulations, which can be expensive, and may affect our business and operating results.

We are subject to federal, state and local regulations relating to the use, handling, storage, disposal and human exposure to hazardous and toxic materials. If we were to violate or become liable under environmental laws in the future as a result of our inability to obtain permits, human error, accident, equipment failure or other causes, we could be subject to fines, costs, or civil or criminal sanctions, face third party property damage or personal injury claims or be required to incur substantial investigation or remediation costs, which could be material, or experience disruptions in our operations, any of which could have a material adverse effect on our

20

Table of Contents

business. In addition, environmental laws could become more stringent over time imposing greater compliance costs and increasing risks and penalties associated with violations, which could harm our business.

We also face increasing complexity in our product design as we adjust to new and future requirements relating to the materials composition of our products, including the restrictions on lead and other hazardous substances applicable to specified electronic products placed on the market in the European Union (Restriction on the Use of Hazardous Substances Directive 2002/95/EC, also known as the RoHS Directive). We also expect that our operations will be affected by other new environmental laws and regulations on an ongoing basis. Although we cannot predict the ultimate impact of any such new laws and regulations, they will likely result in additional costs, and could require that we change the design and/or manufacturing of our products, any of which could have a material adverse effect on our business.

Risks Related to this Offering

There is no existing market for our common stock, and we do not know if one will develop that will provide you with adequate liquidity.

Currently there is no public market for our common stock. Investor interest in us may not lead to the development of an active trading market. The initial public offering price for the shares will be negotiated between us and representatives of the underwriters and may not be indicative of prices that will prevail in the open market following this offering. You may not be able to resell our common stock at or above the initial public offering price.

The trading price of our common stock is likely to be volatile, and you might not be able to sell your shares at or above the initial public offering price.

Though our common stock has no prior trading history, the trading prices of technology company securities in general have been highly volatile. Accordingly, the trading price of our common stock is likely to be subject to wide fluctuations. Factors, in addition to those outlined elsewhere in this prospectus, that may affect the trading price of our common stock include:

21

Table of Contents

Future sales of shares by existing stockholders could cause our stock price to decline.

Attempts by existing stockholders to sell substantial amounts of our common stock in the public market after the contractual lock-up and other legal restrictions on resale discussed in this prospectus lapse could cause the trading price of our common stock to decline significantly. Based on shares outstanding as of June 30, 2006, upon completion of this offering, we will have outstanding             shares of common stock, assuming no exercise of the underwriters’ over-allotment option. Of these shares, only shares of common stock sold in this offering will be freely tradable, without restriction, in the public market. Morgan Stanley & Co. Incorporated and Merrill Lynch, Pierce, Fenner & Smith Incorporated may, in their collective sole discretion, permit our officers, directors, employees and current stockholders who are subject to a 180-day contractual lock-up to sell shares prior to the expiration of the lock-up agreements. The lock-up is subject to extension under certain circumstances. For additional information, see “Shares Eligible for Future Sale—Lock-Up Agreements.”

After the lock-up agreements pertaining to this offering expire, an additional             shares will be eligible for sale in the public market, including             shares held by directors, executive officers and other affiliates, which will be subject to volume limitations under Rule 144 under the Securities Act. In addition,             shares subject to outstanding options and reserved for future issuance under our 1998 stock option plan will become eligible for sale in the public market to the extent permitted by the provisions of various vesting agreements, the lock-up agreements and Rules 144 and 701 under the Securities Act. If these additional shares are sold, or if it is perceived that they will be sold, in the public market, the trading price of our common stock could decline. See “Shares Eligible for Future Sale” for more information regarding shares of our common stock that existing stockholders may sell after this offering.

If securities analysts do not publish research or reports about our business or if they downgrade our stock, the price of our stock could decline.

The research and reports that industry or financial analysts publish about us or our business will likely have an effect on the trading price of our common stock. If an industry analyst decides not to cover our company, or if an industry analyst decides to cease covering our company at some point in the future, we could lose visibility in the market, which in turn could cause our stock price to decline. If an industry analyst downgrades our stock, our stock price would likely decline rapidly in response.

The concentration of our capital stock ownership with insiders upon the completion of this offering will likely limit your ability to influence corporate matters.

We anticipate that our executive officers, directors, current five percent or greater stockholders and affiliated entities will together beneficially own approximately             percent of our common stock outstanding after this offering. As a result, these stockholders, acting together, will have significant influence over all matters that require approval by our stockholders, including the election of directors and approval of significant corporate transactions. Corporate action might be taken even if other stockholders, including those who purchase shares in this offering, oppose them. This concentration of ownership might also have the effect of delaying or preventing a change of control of our company that other stockholders may view as beneficial.

Our management will have broad discretion over the use of the proceeds from this offering and might not apply the proceeds of this offering in ways that increase the value of your investment.

Our management will have broad discretion to use the net proceeds from this offering. Though at this time we have not designated the net proceeds for specific projects, we expect to use the net proceeds from this offering for general corporate purposes, including working capital, and repayment of building loans. We may also use net proceeds for other purposes, including capital expenditures, and for possible investments in, or acquisitions of, complementary products or technologies, although we have no specific plans at this time to do so. Management may fail to use these funds effectively to yield a significant return, or any return, on any investment of these net proceeds.

Table of Contents

You will experience immediate and substantial dilution in the net tangible book value of the shares you purchase in this offering.

The initial public offering price of our common stock will be substantially higher than the book value per share of the outstanding common stock after this offering. Therefore, based on an assumed offering price of $             per share, if you purchase our common stock in this offering, you will suffer immediate and substantial dilution of approximately $             per share. If the underwriters exercise their over-allotment option, or if outstanding options to purchase our common stock are exercised, you will experience additional dilution.

Provisions of our certificate of incorporation and bylaws and Delaware law might discourage, delay or prevent a change of control of our company or changes in our management and, as a result, depress the trading price of our common stock.

Our certificate of incorporation and bylaws contain provisions that could discourage, delay or prevent a change in control of our company or changes in our management that the stockholders of our company may deem advantageous. These provisions:

In addition, we are subject to Section 203 of the Delaware General Corporation Law, which, subject to some exceptions, prohibits “business combinations” between a Delaware corporation and an “interested stockholder,” which is generally defined as a stockholder who becomes a beneficial owner of 15% or more of a Delaware corporation’s voting stock for a three-year period following the date that the stockholder became an interested stockholder. Section 203 could have the effect of delaying, deferring or preventing a change in control that our stockholders might consider to be in their best interests. See “Description of Capital Stock.”

These anti-takeover defenses could discourage, delay or prevent a transaction involving a change in control of our company. These provisions could also discourage proxy contests and make it more difficult for you and other stockholders to elect directors of your choosing and cause us to take corporate actions other than those you desire.

We do not expect to pay any cash dividends for the foreseeable future.

We do not anticipate that we will pay any cash dividends to holders of our common stock in the foreseeable future. Accordingly, investors must rely on sales of their common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investment. Investors seeking cash dividends in the foreseeable future should not purchase our common stock.
