ITEM 1. BUSINESS
Corporate Profile
Cognex® Corporation (“Cognex” or the “Company,” each of which includes, unless the context indicates otherwise, Cognex Corporation and its subsidiaries) was incorporated in Massachusetts in 1981. Its corporate headquarters are located at One Vision Drive, Natick, Massachusetts 01760 and its telephone number is (508) 650-3000.
The Company designs, develops, manufactures, and markets machine vision systems, or computers that can “see,” which are used to automate a wide range of manufacturing processes where vision is required. Machine vision is important for applications in which human vision is inadequate to meet requirements for feature size, accuracy, or speed, or in instances where substantial cost savings are obtained through the reduction of direct labor or improved product quality. Today, many types of manufacturing equipment require machine vision because of the increasing demands for speed and accuracy in manufacturing processes, as well as the decreasing feature size of items being manufactured.
The Company has two operating divisions: the Modular Vision Systems Division (MVSD), based in Natick, Massachusetts, and the Surface Inspection Systems Division (SISD), based in Alameda, California. MVSD designs, develops, manufactures, and markets modular vision systems that are used to automate the manufacture of discrete items, such as semiconductor chips, cellular phones, and light bulbs, by locating, identifying, inspecting, and measuring them during the manufacturing process. SISD designs, develops, manufactures, and markets surface inspection vision systems that are used to inspect the surfaces of materials processed in a continuous fashion, such as paper, metals, plastics, and non-wovens, to ensure there are no flaws or defects on the surfaces. Historically, MVSD has been the source of the majority of the Company’s revenue, representing approximately 84% of total revenue in 2005.
What is Machine Vision?
Since the beginning of the Industrial Revolution, human vision has played an indispensable role in the process of manufacturing products. Human eyes did what no machines could do themselves: locating and positioning work, tracking the flow of parts, and inspecting output for quality and consistency. Today, however, the requirements of many manufacturing processes have surpassed the limits of human eyesight. Manufactured items often are produced too quickly or with tolerances too small to be analyzed by the human eye. In response to manufacturers’ needs, “machine vision” technology emerged, providing manufacturing equipment with the gift of sight. The Company believes that virtually every manufacturer that makes products in an automated process can achieve better quality and manufacturing efficiency by using machine vision.

Machine Vision Market
Cognex serves a wide array of markets around the world that use the Company’s products to replace human vision in a variety of industrial applications. While machine vision systems were first widely embraced by manufacturers of electronic components who needed this technology to produce computer chips with decreasing geometries, advances in technology and easy-to-use interfaces have made machine vision available to a broader range of users. Today, the Company’s products are at work solving vision applications in many industries, including semiconductors, electronics, automotive, food and beverage, healthcare, pharmaceuticals, and high-speed inspection of materials, such as paper and metals.
The Company’s customers can be classified into three markets: semiconductor and electronics capital equipment, discrete factory automation, and surface inspection. Semiconductor and electronics capital equipment manufacturers purchase Cognex machine vision systems and integrate them into the capital equipment that they manufacture and then sell to their customers in the semiconductor and electronics industries that either make computer chips or make printed circuit boards containing computer chips. Although the Company sells to original equipment manufacturers (OEMs) in a number of industries, these semiconductor and electronics OEMs have historically been large consumers of the Company’s products. Sales to semiconductor and electronics capital equipment manufacturers represented approximately 27% of the Company’s total revenue in 2005.
Discrete manufacturers in the factory automation area include a wide array of manufacturers who use machine vision for applications in a variety of industries, including the automotive, consumer electronics, food and beverage, healthcare, pharmaceutical, and aerospace industries. The majority of these customers are end users who purchase Cognex machine vision systems and install them directly on their production lines. These customers, who typically have limited computer programming or machine vision experience, purchase Cognex products from the Company’s direct sales force, from a distributor, or from a system integrator or machine builder that is experienced in machine vision technology. System integrators are hired by end users to help them develop a vision application for their production line, whereas machine builders are hired by end users to build a complete, custom machine that incorporates machine vision. Sales to discrete factory automation customers represented approximately 57% of the Company’s total revenue in 2005.
The last category, surface inspection customers, includes manufacturers of materials processed in a continuous fashion, such as paper, metals, plastics, and nonwovens. These customers need sophisticated machine vision to detect and classify defects in the surfaces of those materials as they are

being processed at high speeds. Surface inspection sales represented approximately 16% of the Company’s total revenue in 2005.
Business Strategy
The Company’s goal is to expand its position as a leading worldwide supplier of machine vision systems for factory automation by offering a complete family of machine vision products to a broad base of manufacturers. Semiconductor and electronics equipment manufacturers have historically been large consumers of the Company’s products. Over the past few years, however, the Company has diversified its customer base beyond the semiconductor and electronics capital equipment sector. Demand from these capital equipment manufacturers is highly cyclical, with periods of investment followed by temporary downturns. At its revenue peak in 2000, sales to semiconductor and electronics capital equipment manufacturers represented approximately 61% of the Company’s total revenue, compared to approximately 27% in 2005, 42% in 2004, and 34% in 2003.
The Company believes that long-term, sustained revenue growth will come from a broad base of manufacturers outside of the semiconductor and electronics capital equipment manufacturer sector. Accordingly, the Company has invested in expanding its product offerings to its discrete factory automation customers, who demand a wide range of easy-to-use products of varying capability and price, and in developing a strong worldwide sales and support infrastructure.
On May 9, 2005, the Company completed is largest acquisition to date when it purchased DVT® Corporation. In recent years, the Company has expanded its product line by adding low-cost, easy-to-use vision products, such as its In-Sight® and Checker® products. However, reaching the many prospects for these products in factories around the world requires a large third-party distribution channel to supplement the Company’s own direct end-user sales force. During 2004, the Company started to build a third-party distribution channel and prior to the DVT acquisition had signed over 40 distributors, primarily in North America. With the acquisition of DVT Corporation, the Company immediately gained a worldwide network of more than 150 additional distributors, all fully trained in selling and supporting machine vision products. The Company believes that it can accelerate its growth in the rapidly developing discrete factory automation market by selling its expanding line of low-cost, easy-to-use products, including the acquired DVT vision sensors, through this newly acquired worldwide distribution channel.
The Company intends to continue to defend its strong position in the semiconductor and electronics capital equipment sector, while selectively expanding into new machine vision applications through the internal development of new products, as well as the acquisition of businesses and technologies.
Products
Cognex offers a full range of machine vision systems designed to meet customer needs at virtually any stage of the manufacturing process and virtually any capability/price point.
Vision Sensors
The Company believes it is firmly positioned in the fast-growing market for vision sensors with its In-Sight and DVT product lines. Vision sensors are machine vision systems that combine a digital camera, software, vision processor, and input/output capability in a low-cost, compact, easy-to-use package. These general-purpose vision sensors are designed to be easily programmed to perform a wide range of vision tasks including part location, identification, measurement, assembly verification, and robotic guidance.
In 2005, the Company expanded the In-Sight 5000 series to include stainless steel vision sensors for the food and beverage industry and high-resolution cameras, while continuing to increase processing power in a rugged, industrial-grade package that meets high standards for shock, vibration, and dust and wash-down protection. The acquisition of the DVT product line complements In-Sight with increased ease of use and color capabilities, in a lower cost package.

Vision sensors are sold to end users, system integrators, and machine builders located in North America, Japan, Europe, and Southeast Asia in a wide range of general manufacturing applications, such as automotive parts and assembly, consumer packaged goods, electronic components, medical devices, and pharmaceuticals.
Expert Sensors
Unlike general-purpose vision sensors that can be programmed to solve a wide variety of vision tasks, expert sensors are designed to deliver very simple, low-cost solutions for specific sensor problems. Because of its low price and ease of use, the Company expects to solve many new manufacturing problems with its Checker series of products.
In 2004, the Company introduced Checker 101, designed to detect the presence or absence of product features. Checker detects or inspects parts by understanding what they look like, providing high reliability and eliminating many of the drawbacks of traditional photoelectric sensors. Late in 2005, the Company introduced Checker 101E, which expands Checker’s capability to include the tracking and rejecting of parts. This capability provides significant value to the customer since it eliminates the need for other industrial equipment, providing higher ease of use and a lower cost solution. Checker is sold through distributors to end users and system integrators located in North America, Japan, Europe, and Southeast Asia in a wide range of general manufacturing industries.
The CPS-1000 is a vision sensor designed for door security; it detects and counts people as they pass through an access-controlled doorway. The CPS-1000 utilizes Cognex’s existing vision software, as well as patented 2D and 3D vision technology that Cognex developed specifically for “people sensing” applications. The CPS-1000 is currently sold to OEMs located in North America.
ID Products
The Company’s ID products are designed to quickly and reliably read codes (e.g. one-dimensional bar codes on labels or two-dimensional marks on parts) that have been stamped, scribed, etched, printed, or otherwise formed directly on the surfaces of manufactured goods ranging from pharmaceutical items to aircraft components to semiconductor wafers. Industrial ID is an increasingly critical tool to ensure the appropriate manufacturing processes are performed in the correct sequence on the right parts. In addition, it can be used to create a history of the part from the beginning of its life to the end, and for use in supply chain management and repair.
In 2005, the Company introduced the In-Sight 5411 and In-Sight 5413 high-resolution, fixed-mount Industrial ID readers. Each model incorporates IDMax™ software, Data Matrix code-reading software based upon Cognex PatMax® technology. IDMax reads reliably despite degradations to the appearance of the code. In addition, the Company introduced the In-Sight 1721 Wafer ID reader that identifies and tracks semiconductor wafers through the manufacturing process.
Early in 2006, the Company introduced the DataMan7500 Series Direct Part Mark hand-held readers for part traceability. Dataman reads everything from the most challenging marks on parts to the easiest printed bar codes. These rugged, self-contained readers incorporate IDMax software and the new UltraLight® illumination system to optimally illuminate marks on various part surfaces.
ID products are sold to OEMs, system integrators, machine builders, and end users located in North America, Japan, Europe, and Southeast Asia in a broad range of industries.
PC-Based Vision Systems
The Company sells a full range of PC-based vision systems that combine the vision power of Cognex’s most advanced vision tools with the processing power of high-speed PCs, provide the flexibility to choose from the widest range of contemporary analog and digital cameras for image acquisition, and facilitate seamless integration of vision into capital equipment.

In addition, SmartView is sold to end users located in Europe and Asia in the paper industry through an OEM relationship with Honeywell International, Inc.
Research, Development, and Engineering
The Company engages in research, development, and engineering (R,D&E) to enhance its existing products and to develop new products and functionality to meet market opportunities. In addition to internal research and development efforts, the Company intends to continue its strategy of gaining access to new technology through strategic relationships and acquisitions where appropriate. The Company considers its on-going efforts in R,D&E to be a key component of its strategy.
At December 31, 2005, the Company employed 166 professionals in R,D&E, most of whom are software developers. The Company’s R,D&E expenses totaled $27,640,000, $27,063,000, and $24,719,000, or approximately 13%, 14%, and 17% of revenue, in 2005, 2004, and 2003, respectively.
Manufacturing
The Company’s MVSD manufacturing organization utilizes a turnkey operation whereby the majority of component procurement, subassembly, final assembly, and initial testing are performed under agreement by third-party contract manufacturers. After the completion of initial testing, the contract manufacturers deliver the products to the Company’s Natick, Massachusetts facility for final testing, quality control, and shipment to the customer. Late in 2005, the Company began moving these activities to Ireland to be closer to its primary contract manufacturer. The contract manufacturers use specified components and assembly and test documentation created and controlled by the Company. From time to time, the Company will procure large quantities of end-of-life components for strategic purposes that will not be consumed within one year. Certain components are presently available only from a single source
The Company’s SISD products are manufactured at its Alameda, California facility, with the exception of the frames on which the cameras and the lights used to illuminate the web are mounted. The manufacturing process at the Alameda facility consists of system design, configuration management and control, component procurement, and subassembly. After the completion of subassembly at the Alameda facility, some of the systems are delivered to the Company’s Kuopio, Finland facility where the frames and lights are manufactured. The manufacturing process at the Kuopio facility consists of system integration final testing, quality control, and shipment to the customer. Certain products are manufactured by third-party contract manufacturers using documentation created and controlled by the Company. Certain servicemarks, and trademarks referenced in this document are the property of their respective owners.
Sales and Service
The Company sells its MVSD and SISD products through a direct sales force in North America, Japan, Europe, and Southeast Asia. Certain of the Company’s low-cost MVSD products are also sold through a worldwide distribution network. At December 31, 2005, the Company’s direct sales force consisted of 241 professionals, including sales and application engineers. The majority of the Company’s sales force holds

Intellectual Property
Because the Company relies on the technical expertise, creativity, and knowledge of its personnel, it utilizes patent, trademark, copyright, and trade secret protection to safeguard its competitive position. At December 31, 2005, the Company had obtained 231 patents on various innovations in the field of machine vision technology and had more than 151 patent applications pending. In addition, the Company makes use of non-disclosure agreements with customers, suppliers, employees, and consultants. The Company attempts to protect its intellectual property by restricting access to its proprietary information by a combination of technical and internal security measures. There can be no assurance, however, that any of the above measures will be adequate to protect the proprietary technology of the Company. Moreover, effective patent, trademark, copyright, and trade secret protection may be unavailable in certain foreign countries.
The Company’s trademark and servicemark portfolio includes various registered marks, including but not limited to, Cognex®, DVT®, In-Sight®, Checker®, PatMax®, VisionPro®, and SmartView®, as well as many common-law marks, including but not limited to, DataManTM, IDMaxTM, and ProofreadTM. In addition, the Company has sought and obtained a number of trademark registrations outside of the United States. All third-party brand names, servicemarks, and trademarks referenced in this document are the property of their respective owners.
The Company’s software products are protected by various security schemes and are primarily licensed to customers pursuant to an agreement that restricts the use of the products to the customer’s purposes, as well as imposes strict limitations on the customer’s use of the Company’s trade secret, proprietary, and other confidential business information to which the customer may have access. The Company has made portions of its source code available to certain customers under very limited circumstances and for restricted uses. If the source code is released to a customer, the customer is required by contract to maintain its confidentiality and, in general, to use the source code solely for internal purposes or for maintenance.
Numerous users of the Company’s products have received notice of patent infringement from the Lemelson Medical, Educational, & Research Foundation, Limited Partnership (the “Partnership”) alleging that their use of the Company’s products infringes certain patents transferred to the Partnership by the late

Table of Contents

Jerome H. Lemelson. The Company does not believe its products infringe any valid and enforceable claims of the Partnership’s patents.
As a result of continuing assertions against current and potential Cognex customers, the Company decided to initiate action against the Partnership in order to preserve its right to sell machine vision products without the threat of legal action against the Company or its customers. Accordingly, on September 23, 1998, the Company filed a complaint against the Partnership seeking a declaration that Lemelson’s machine vision patents are invalid, unenforceable, and not infringed by either Cognex or by any users of Cognex products.
On January 23, 2004, the U.S. District Court of Nevada issued a court order ruling in favor of Cognex and finding that all of the Lemelson patent claims in suit are unenforceable, invalid, and not infringed by Cognex. The Partnership filed a notice of appeal with respect to this decision with the U.S. Court of Appeals for the Federal Circuit. A sub-panel of three of the judges of the Court of Appeals rendered its decision in favor of Cognex on September 9, 2005. On November 16, 2005, the U.S. Court of Appeals denied the Partnership’s petition for a rehearing by the entire bench. On December 22, 2005, the Partnership informed the District Court of Arizona, where related cases are pending, that it will not seek further review of the U.S. Court of Appeals’ decision. Furthermore, the deadline for requesting review by the the U.S. Supreme Court has expired. Accordingly, no further appeals are available to Lemelson and the matter has been finally resolved in Cognex’s favor.
Compliance with Environmental Provisions
The Company’s capital expenditures, earnings, and competitive position are not materially affected by compliance with federal, state, and local environmental provisions which have been enacted or adopted to regulate the distribution of materials into the environment.
Competition
The machine vision market is highly fragmented and the Company’s competitors vary depending upon market segment, geographic region, and application niche. The Company’s competitors are typically other vendors of machine vision systems and manufacturers of image processing systems and sensors. In addition, in the semiconductor and electronics capital equipment market, the Company also competes with the internal engineering efforts of current or prospective customers. Any of these competitors may have greater financial and other resources than the Company. Although the Company considers itself to be one of the leading machine vision companies in the world, reliable estimates of the machine vision market and the number of competitors are not available.
The Company’s ability to compete depends upon its ability to design, manufacture, and sell high-quality products, as well as its ability to develop new products that meet evolving customer requirements. The primary competitive factors affecting the choice of a machine vision system include vendor reputation, product functionality and performance, ease of use, price, and post-sales support. The importance of each of these factors varies depending upon the specific customer’s needs.
Backlog
At December 31, 2005, the Company’s backlog totaled $33,069,000, compared to $29,023,000 at December 31, 2004. Backlog reflects purchase orders for products scheduled for shipment primarily within three months at MVSD and primarily within six months at SISD. The level of backlog at any particular date is not necessarily indicative of future revenue of the Company. The Company’s low-cost vision sensors typically ship within one week of when the order is booked. In addition, delivery schedules may be extended and orders may be canceled at any time subject to certain cancellation penalties.
Employees
At December 31, 2005, the Company employed 740 persons, including 375 in sales, marketing, and service activities; 166 in research, development, and engineering; 81 in manufacturing and quality

Additional risks and uncertainties that we are unaware of, or that we currently deem immaterial, also may become important factors that affect our company in the future. If any of these risks were to occur, our business, financial condition, or results of operations could be materially and adversely affected. This section includes or refers to certain forward-looking statements; you should read the explanation of the qualifications and limitations on such forward-looking statements found in the section captioned “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” appearing on page 14 of the Annual Report to Shareholders for the year ended December 31, 2005, which is attached as Exhibit 13 hereto, and is incorporated herein by reference.
Unless the context otherwise requires, the words “Cognex,” “we,” “our,” “us,” and “our company” refer to Cognex Corporation and its consolidated subsidiaries.
Unfavorable changes in economic conditions and capital spending may negatively impact our operating results.
Our revenue is dependent upon the capital spending trends of manufacturers in a number of industries and regions. These spending levels are, in turn, impacted by global economic conditions. Our operating results have been materially adversely affected in the past, and could be materially adversely affected in the future, as a result of unfavorable economic conditions and reduced capital spending by manufacturers worldwide.
Downturns in the semiconductor and electronics industries may adversely affect our business.
In 2005, approximately 27% of our revenue was derived from semiconductor and electronics capital equipment manufacturers. This concentration was as high as 61% in 2000 during its revenue peak. The semiconductor and electronics industries are highly cyclical and have historically experienced periodic downturns, which have often had a severe effect on demand for production equipment that incorporates our products. While we have been successful in recent years in diversifying our business beyond OEM customers who serve the semiconductor and electronics industries, our business is still impacted by capital expenditures in these industries, which, in turn, are dependent upon the market demand for products containing computer chips. As a result, our operating results in the foreseeable future could be significantly and adversely affected by a slowdown in either of these industries.
Economic, political, and other risks associated with international sales and operations could adversely affect our business and operating results.
In 2005, approximately 63% of our revenue was derived from customers located outside of the United States. We anticipate that international sales will continue to account for a significant portion of our revenue. We intend to continue to expand our operations outside of the United States and may enter

9


Table of Contents

additional international markets, which will require significant management attention and financial resources. As a result, our operations are subject to the risks inherent in international sales, including, among other things,
    various regulatory requirements,
 
    transportation delays,
 
    difficulties in staffing and managing foreign sales operations, and
 
    potentially adverse tax consequences.
In addition, fluctuations in foreign currency exchange rates may render our products less competitive relative to local product offerings, or could result in significant foreign currency losses if not properly hedged. We are also subject to the political risks inherent in international operations and their impact on the global economy, including economic disruption from acts of war or terrorism, particularly in the aftermath of the terrorist attacks of September 11, 2001. Any of these factors could have a material adverse effect on our operating results.
Fluctuations in foreign exchange rates could materially affect our reported results.
We face exposure to adverse movements in foreign currency exchange rates as a significant portion of our revenue, expenses, assets, and liabilities are denominated in currencies other than the functional currencies of our company. In certain instances, we utilize derivative instruments to hedge against foreign currency fluctuations. These contracts are used to reduce our risk associated with foreign currency exchange rate changes, as the gains or losses on the derivative are intended to offset the losses or gains on the underlying exposure. We do not engage in foreign currency speculation. The success of our foreign currency risk management program depends upon forecasts of transaction activity denominated in various currencies. To the extent that these forecasts are overstated or understated during periods of currency volatility, we could experience unanticipated foreign currency gains or losses that could have a material impact on our results of operations. In addition, our failure to identify new exposures and hedge them in a timely manner may result in material foreign currency gains or losses.
The loss of a large customer could have an adverse effect on our operating results.
In 2005, our top five customers accounted for approximately 9% of total revenue. In recent years, our expansion into the end-user marketplace has reduced its reliance upon the revenue from any one of our larger OEM customers. Nevertheless, the loss of, or significant curtailment of purchases by, any one or more of our larger customers could have a material adverse effect on our operating results.
The failure of a key supplier to deliver quality product in a timely manner or our inability to obtain components for our products could adversely affect our operating results.
A significant portion of our MVSD inventory is manufactured by a third-party contractor. As a result, we are dependent upon this contractor to provide quality product and meet delivery schedules. We engage in extensive product quality programs and processes, including actively monitoring the performance of our third-party manufacturers; however, we may not detect all product quality issues through these programs and processes. In addition, a variety of components used in our products are only available from a single source. The announcement by a single-source supplier of a last-time component buy could result in our purchase of a significant amount of inventory that, in turn, could lead to an increased risk of inventory obsolescence. An interruption in, termination of, or material change in the purchase terms of any single-source components could have a material adverse effect on our operating results.
Our business could suffer if we lose the services of, or fail to attract, key personnel.
We are highly dependent upon the management and leadership of Robert J. Shillman, our Chief Executive Officer and Chairman of the Board of Directors, as well as other members of our senior management team, including James F. Hoffmaster who was promoted to President of Cognex Corporation during 2004 with full responsibility for running our day-to-day operations. Although we have retained many experienced and qualified senior managers, the loss of key personnel could have a material adverse effect on our company. Our continued growth and success also depends upon our

10


Table of Contents

ability to attract and retain skilled employees and on the ability of our officers and key employees to effectively manage the growth of our business through the implementation of appropriate management information systems and internal controls.
Our products may contain design or manufacturing defects, which could result in reduced demand, significant delays, or substantial costs.
If flaws in either the design or manufacture of our products were to occur, we could experience a rate of failure in our products that could result in significant delays in shipment and material repair or replacement costs. While we engage in extensive product quality programs and processes, including actively monitoring and evaluating the quality of our component suppliers and contract manufacturers, these actions may not be sufficient to avoid a product failure rate that results in:
    substantial delays in shipment,
 
    significant repair or replacement costs, or
 
    potential damage to our reputation,
any of which could have a material adverse effect on our operating results.
Our failure to accurately forecast customer demand could result in inventory obsolescence and resulting charges.
In recent years, we have expanded our presence in the end-user marketplace. Our end-user business typically operates with a relatively short backlog and our production plans are based on internal forecasts of customer demand. Due to these factors, we have in the past, and may again in the future, fail to accurately forecast demand, in terms of both volume and configuration for either our legacy or next-generation products. Our failure to accurately forecast customer demand has led to, and may again in the future lead to, an increased risk of inventory obsolescence and resulting charges.
Our failure to develop new products and to respond to technological changes could result in the loss of our market share and a decrease in our revenues.
The market for our products is characterized by rapidly changing technology. Accordingly, we believe that our future success will depend upon our ability to develop or acquire new products with improved price/performance and introduce them to the marketplace in a timely manner. We may not be able to introduce and market new products successfully and respond effectively to technological changes or new product introductions by competitors. Our ability to keep pace with the rapid rate of technological change in the high-technology marketplace could have a material adverse effect on our operating results.
If we fail to successfully defend our intellectual property, our competitive position and operating results could suffer.
We rely heavily on our proprietary software technology and hardware designs, as well as the technical expertise, creativity, and knowledge of our personnel. Although we use a variety of methods to protect our intellectual property, we rely most heavily on patent, trademark, copyright, and trade secret protection, as well as non-disclosure agreements with customers, suppliers, employees, and consultants. We also attempt to protect our intellectual property by restricting access to our proprietary information by a combination of technical and internal security measures. These measures, however, may not be adequate to:
    protect our proprietary technology,
 
    protect our patents from challenge, invalidation, or circumvention, or
 
    ensure that our intellectual property will provide us with competitive advantages.
Any of these adverse circumstances could have a material effect on our operating results. We refer you to the section captioned “Intellectual Property,” appearing in Part I — Item I of this report.

11


Table of Contents

Our company may be subject to costly litigation.
From time to time, we may be subject to various claims and lawsuits by competitors, customers, or other parties arising in the ordinary course of business, including lawsuits charging patent infringement. These matters can be time-consuming, divert our management’s attention and resources, and cause us to incur significant expenses. Furthermore, the results of any of these actions may have a material adverse effect on our operating results.
Increased competition may result in decreased demand or prices for our products and services.
We compete with other vendors of machine vision systems, the internal engineering efforts of our current or prospective customers, and the manufacturers of image processing systems and sensors. Any of these competitors may have greater financial and other resources than we do. In recent years, ease-of-use and product price have become significant competitive factors in the end-user marketplace. We may not be able to compete successfully in the future and our investments in research and development, sales and marketing, and service activities may be insufficient to enable us to maintain our competitive advantage. In addition, competitive pressures could lead to price erosion that could materially and adversely affect our operating results. We refer you to the section captioned “Competition,” appearing in Part I — Item 1 of this report.
Implementation of our acquisition strategy may not be successful, which could affect our ability to increase our revenue or profitability.
We have in the past acquired, and will in the future consider the acquisition of, businesses and technologies in the machine vision industry. If we acquire other businesses or technologies in the future, our business may be negatively impacted by risks related to those acquisitions. These risks include, among others:
    the diversification of management’s attention from other operational matters,
 
    the inability to realized expected synergies resulting from the acquisition,
 
    the failure to retain key customers or employees, and
 
    the impairment of acquired intangible assets resulting from technological obsolescence or lower-than-expected cash flows from the acquired assets.
Acquisitions are inherently risky and the inability the effectively manage these risks could have a material adverse effect on our operating results.
Attractive acquisition opportunities may not be available to us.
Our business strategy includes selective expansion into other machine vision applications through the acquisition of businesses and technologies. Since 1995, we have completed ten business and technology acquisitions, including the acquisition of DVT Corporation in 2005. We plan to continue to seek opportunities to expand our product line, customer base, distribution network, and technical talent through acquisitions in the machine vision industry. However, we may not have the opportunity to make suitable acquisitions on favorable terms in the future, which could negatively impact the growth of our business. We expect that other companies in the machine vision industry will compete with us to acquire compatible businesses. This competition could increase prices for businesses and technologies that we would likely pursue, and our competitors may have greater resources than we do.
The trading price of our common stock may be volatile.
The price of our common stock has historically experienced significant volatility due to:
    fluctuations in our revenue and earnings,
 
    changes in the market’s expectations for our growth,
 
    overall equity market conditions,
 
    conditions relating to the market for technology stocks,
 
    general economic conditions, and
 
    other factors unrelated to our operations.

The stock markets have experienced extreme price volatility in recent years. This volatility has had a substantial effect on the market prices of securities issued by many technology companies, such as our company, often for reasons unrelated to the operating results of the specific company.

In 1995, the Company purchased an 83,000 square-foot office building adjacent to its corporate headquarters. The building is currently largely occupied with tenants who have lease agreements that expire at various dates through 2009. The Company uses a portion of the space for storage and product demonstrations.
