NOTE 1: Summary of Significant Accounting Policies

As permitted by the rules of the Securities and Exchange Commission applicable to Quarterly Reports on Form 10-Q, these notes are condensed and do not contain all disclosures required by generally accepted accounting principles. Reference should be made to the consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2003.

In the opinion of the management of Cognex Corporation, the accompanying consolidated unaudited financial statements contain all adjustments necessary to present fairly the Company’s financial position at July 4, 2004, and the results of its operations for the three-month and six-month periods ended July 4, 2004 and June 29, 2003, and changes in stockholders’ equity and cash flows for the periods presented.

The results disclosed in the Consolidated Statements of Operations for the three-month and six-month periods ended July 4, 2004 are not necessarily indicative of the results to be expected for the full year. Certain amounts reported in prior periods have been reclassified to be consistent with the current period presentation.

Effective July 1, 2004, the Massachusetts Business Corporation Act (the “Act”) eliminated the concept of treasury shares. Under the Act, shares previously classified as treasury shares are to be treated as authorized but unissued shares of common stock. As a result of this change, the Company has reclassified treasury shares at July 4, 2004. The shares which were previously classified as treasury stock are now classified as authorized, but unissued shares of common stock on the Consolidated Balance Sheet.

Stock-Based Compensation Plans

The Company recognizes compensation costs using the intrinsic value based method described in Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees.” Net income (loss) and net income (loss) per share as reported in these consolidated financial statements and on a pro forma basis, as if the fair value based method described in Statement of Financial Accounting Standards No. 123, “Accounting for Stock-Based Compensation,” had been adopted, are as follows (in thousands, except per share amounts):

NOTE 1: Summary of Significant Accounting Policies (continued)

For the purpose of providing pro forma disclosures, the fair values of stock options granted were estimated using the Black-Scholes option-pricing model with the following weighted-average assumptions:

NOTE 2: Cash, Cash Equivalents, and Investments

Cash, cash equivalents, and investments consist of the following (in thousands):

On June 30, 2000, Cognex Corporation became a Limited Partner in Venrock Associates III, L.P., a venture capital fund. A director of the Company is a Managing General Partner of Venrock Associates. The Company has committed to a total investment in the limited partnership of up to $25,000,000, of which $15,125,000 and $13,625,000 had been contributed as of July 4, 2004 and December 31, 2003, respectively. The commitment to contribute capital expires on January 1, 2005, and the Company does not have the right to withdraw from the partnership prior to December 31, 2010.

At July 4, 2004, the carrying value of this investment was $11,513,000 compared to an estimated fair value, as determined by the General Partner, of $10,670,000. The unrealized loss of $843,000 was determined to be temporary.

NOTE 3: Inventories

Inventories consist of the following (in thousands):

In the fourth quarter of 2001, the Company recorded a $16,300,000 charge in “Cost of product revenue” on the Consolidated Statements of Operations for excess inventories and purchase commitments resulting from an extended slowdown in the semiconductor and electronics industries, as well as the expected transition to newer Cognex hardware platforms by the Company’s OEM customers. A total of $12,500,000 of this charge represented reserves against existing inventories and was accordingly included in “Inventories” on the Consolidated Balance Sheet at December 31, 2001. The remaining $3,800,000 of the charge represented commitments to purchase excess components and systems from various suppliers and accordingly was included in “Accrued Expenses” on the Consolidated Balance Sheet at December 31, 2001.

The following table summarizes the changes during the current year in the inventory-related reserves that were established in the fourth quarter of 2001 (in thousands):

A favorable settlement of the remaining purchase commitments may result in a recovery of a portion of the remaining $1,400,000 accrued at July 4, 2004.

NOTE 5: Goodwill

The Company has two reporting units with goodwill, the Modular Vision Systems Division (MVSD) and the Surface Inspection Systems Division (SISD), which are also reportable segments.

The changes in the carrying amount of goodwill during the six-month period ended July 4, 2004 are as follows (in thousands):

NOTE 6: Warranty Obligations

The Company warrants its hardware products to be free from defects in material and workmanship for periods ranging from six months to two years from the time of sale based upon the product being sold and the terms of the customer’s contract. Estimated warranty obligations are evaluated and recorded at the time of sale based upon historical costs to fulfill warranty obligations. Provisions may also be recorded subsequent to the time of sale whenever specific events or circumstances impacting product quality that would not have been taken into account using historical data become known. Warranty obligations are included in “Accrued expenses” on the Consolidated Balance Sheets.

The changes in the warranty obligation are as follows (in thousands):

NOTE 7: Indemnification Provisions

Except as limited by Massachusetts law, the by-laws of the Company require it to indemnify certain current or former directors, officers, and employees of the Company against expenses incurred by them in connection with each proceeding in which he or she is involved as a result of serving or having served in certain capacities. Indemnification is not available with respect to a proceeding as to which it has been adjudicated that the person did not act in good faith in the reasonable belief that the action was in the best interests of the Company. The maximum potential amount of future payments the Company could be required to make under these provisions is unlimited. The Company has never incurred significant costs related to these indemnification provisions. As a result, the Company believes the estimated fair value of these provisions is minimal.

The Company accepts standard limited indemnification provisions in the ordinary course of business, whereby it indemnifies its customers for certain direct damages incurred in connection with third-party patent or other intellectual property infringement claims with respect to the use of the Company’s products. The term of these indemnification provisions generally coincides with the customer’s use of the Company’s products. The maximum potential amount of future payments the Company could be required to make under these provisions is always subject to fixed monetary limits. The Company has never incurred significant costs to defend lawsuits or settle claims related to these indemnification provisions. As a result, the Company believes the estimated fair value of these provisions is minimal.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 7: Indemnification Provisions (continued)

The Company also accepts limited indemnification provisions from time to time, whereby it indemnifies customers for certain direct damages incurred in connection with bodily injury and property damage arising from the installation of the Company’s products. The term of these indemnification provisions generally coincides with the period of installation. The maximum potential amount of future payments the Company could be required to make under these provisions is limited and is recoverable under the Company’s insurance policies. As a result of this coverage, and the fact that the Company has never incurred significant costs to defend lawsuits or settle claims related to these indemnification provisions, the Company believes the estimated fair value of these provisions is minimal.

NOTE 8: Guarantees

On March 25, 2004, the Company provided standby letters of credit totaling 3,146,280,000 Yen (or approximately $29,057,000 based upon the exchange rate at July 4, 2004) to taxing authorities in Japan. These letters of credit replace the bank guarantees that the Company provided on May 27, 2003, which were scheduled to expire in accordance with their terms, and the investments that collateralize these letters of credit are included in short-term and long-term investments on the Consolidated Balance Sheets. The Tokyo Regional Taxation Bureau (TRTB) has asserted that Cognex Corporation has a permanent establishment in Japan that would require certain income, previously reported on U.S. tax returns for the years ended December 31, 1997 through December 31, 2001, to be subject instead to taxation in Japan. The Company disagrees with this position and believes that this assertion is inconsistent with principles under the U.S. — Japan income tax treaty. The Company has filed a notice of objection and request for deferral of tax payment and intends to contest this assessment vigorously, although no assurances can be made that the Company will prevail in this matter. In September 2003, the Company also filed a request with the Internal Revenue Service Tax Treaty Division for competent authority assistance. Until this matter is resolved, the Company is required to provide bank guarantees or standby letters of credit to collateralize these tax assessments. These letters of credit expire in approximately one year. Should the TRTB prevail in its assertion, the income in question would be taxable in Japan and the Company would be required to pay approximately $29,057,000 in taxes, interest and penalties to Japanese taxing authorities. The Company would then be entitled to recoup the majority of this amount from taxing authorities in the U.S.

NOTE 9: Net Income Per Share

Net income per share is calculated as follows (in thousands, except per share amounts):

Stock options to purchase 736,533 and 728,207 shares of common stock were outstanding during the three-month and six-months periods ended July 4, 2004, respectively, and 4,617,831 and 4,612,832 for the same periods in 2003 but were not included in the calculation of diluted net income per common share because the options’ exercise prices were greater than the average market price of the Company’s common stock during those periods.

NOTE 10: Segment Information

The Company has two reportable segments: the Modular Vision Systems Division (MVSD) and the Surface Inspections Systems Division (SISD). MVSD designs, develops, manufactures, and markets modular vision systems that are used to control the manufacturing of discrete items 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 surfaces of materials that are processed in a continuous fashion to ensure there are no flaws or defects in the surfaces. Segments are determined based upon the way that management organizes its business for making operating decisions and assessing performance. The Company evaluates segment performance based upon income or loss from operations, excluding unusual items.

NOTE 10: Segment Information (continued)

The following table summarizes information about the Company’s segments (in thousands):

Reconciling items consist of unallocated corporate expenses, which primarily include corporate headquarters costs and patent infringement litigation. Asset information by segment is not produced internally for use by the chief operating decision maker, and therefore, is not presented. Asset information is not provided because the cash and investments are commingled and the divisions share assets and resources in a number of locations around the world.

NOTE 11: Acquisitions

Acquisition of Siemens Dematic AG Wafer Identification Business

On March 31, 2003, the Company acquired the wafer identification business of Siemens Dematic AG, a subsidiary of Siemens AG.

NOTE 11: Acquisitions (continued)

The original purchase price consisted of 7,000,000 Euros in cash (or approximately $7,630,000) paid on March 31, 2003, with the potential for an additional cash payment in 2005 of up to 1,700,000 Euros (or approximately $2,068,000) depending upon the achievement of certain performance criteria. The contingent consideration will be recorded as purchase price when paid and will be allocated to goodwill. The March 31, 2003 cash payment of 7,000,000 Euros was based upon an estimated balance sheet for the wafer identification business as of March 31, 2003. After receipt of the final March 31, 2003 balance sheet and resolution of certain items in dispute, Siemens reimbursed Cognex 796,000 Euros (or $868,000).

The final purchase price of 6,204,000 Euros (or approximately $6,762,000) was allocated as follows: $616,000 to inventories; $274,000 to accounts receivable; $25,000 to accrued expenses; $4,469,000 to customer contracts and relationships, to be amortized over eight years; $447,000 to complete technology, to be amortized over five years; $98,000 to patents, to be amortized over five years; $44,000 to non-compete agreements, to be amortized over three years; and $839,000 to goodwill, assigned to the MVSD segment, none of which is deductible for tax purposes.

Acquisition of Gavitec AG Machine Vision Business

On December 1, 2003, the Company acquired the machine vision business of Gavitec AG. Gavitec produces machine vision products for direct part mark identification (or Industrial ID), which can read markings on the surfaces of manufactured items to collect data about product components during the manufacturing process and trace the manufacturing history of the components during the product’s lifetime. Under the terms of the agreement, the Company acquired all of the tangible and intangible assets and assumed certain liabilities associated with Gavitec’s machine vision business. The results of operations of the acquired business have been included in the Company’s consolidated results of operations since the date of the acquisition. The historical results of operations of the acquired business were not material compared to the consolidated results of operations, and therefore, pro forma results are not presented.

The purchase price consisted of 3,800,000 Euros in cash (or approximately $4,534,000), including 3,500,000 Euros paid at closing, 100,000 Euros to be paid on December 1, 2004, and 200,000 Euros to be paid on December 1, 2005. There is the potential for an additional cash payment of up to 250,000 Euros in both 2004 and 2005 (or approximately $304,000 in each year) depending upon the achievement of certain performance criteria. The contingent consideration will be recorded as purchase price when paid and will be allocated to goodwill.

NOTE 12: Dividends

On April 22, 2004, the Company’s Board of Directors declared a cash dividend of $0.06 per share. The dividend was paid on May 21, 2004 to all stockholders of record at the close of business on May 7, 2004.

NOTE 13: Subsequent Event

On July 22, 2004, the Company’s Board of Directors declared a cash dividend of $0.08 per share. The dividend is payable on August 20, 2004 to all stockholders of record at the close of business on August 6, 2004. Future dividends will be declared at the discretion of the Board of Directors and will depend upon such factors as the Board of Directors deems relevant. The Board of Directors may modify the Company’s dividend policy from time to time.

Results of Operations

Executive Overview

Cognex Corporation (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. The Company’s Modular Vision Systems Division (MVSD) specializes in machine vision systems that are used to automate the manufacture of discrete items, while the Company’s Surface Inspection Systems Division (SISD) specializes in machine vision systems that are used to inspect the surfaces of materials processed in a continuous fashion.

In addition to product revenue derived from the sale of machine vision systems, the Company also generates revenue by providing maintenance and support, education, consulting, and installation services to its customers. The Company has two primary types of customers: original equipment manufacturers (OEMs) and end users. OEM customers purchase Cognex machine vision systems and integrate them into the capital equipment that they manufacture and then sell to their customers, primarily companies in the semiconductor and electronics industries that either make computer chips or make printed circuit boards containing computer chips. End-user customers purchase Cognex machine vision systems and install them directly on their production lines to automate the manufacture of a wide range of items in a variety of industries.

Over the past few years, the Company has been successful in diversifying its customer base beyond OEMs serving the semiconductor and electronics industries. These industries are highly cyclical, with periods of investment followed by temporary downturns, which have had a severe effect on demand for capital equipment that incorporates the Company’s products. During the first half of 2004, the Company

14

experienced an increase in demand from capital equipment manufacturers serving the semiconductor and electronics industries, with sales to these customers increasing 104% from the same period in 2003.

While sales to these capital equipment manufacturers contributed most significantly to the Company’s total revenue growth for the first half of 2004, sales to all other customers also increased from the prior year by 20% due to higher demand from end-user customers in a variety of industries, most notably the electronics industry. While the capital spending trends of the Company’s end-user customers have also been negatively impacted by global economic conditions, the industries and applications of these customers are far more diversified than those of its OEM customers.

The Company’s total revenue during the first half of 2004 increased 48% from the prior year. During 2004, the Company continued to keep tight control over expenses and invested only in strategic areas that will help drive revenue growth, such as sales and marketing. The growth in revenue, along with expense control, resulted in the Company reporting an operating profit of 24% of revenue for the first half of 2004 compared to 9% of revenue for the same period in 2003.

Revenue

Revenue for the three-month and six-month periods ended July 4, 2004 totaled $54,467,000 and $102,636,000, respectively, compared to $36,622,000 and $69,510,000 for the same periods in 2003, representing a 49% increase for the three-month period and a 48% increase for the six-month period. The majority of this growth came from sales to capital equipment manufacturers serving the semiconductor or electronics industries. Sales to these customers for the three-month and six-month periods ended July 4, 2004 increased $12,563,000, or 109% and $23,860,000, or 104%, respectively. Sales to all other customers increased $5,282,000, or 21%, for the three-month period and $9,266,000, or 20%, for the six-month period due to higher demand from end-user customers primarily in the electronics industry. Although sales to these other customers grew from the prior year, they decreased as a percentage of total revenue to 56% and 54% for the three-month and six-month periods ended July 4, 2004, respectively, compared to 69% and 67% for the same periods in 2003 due to the significant increase in sales to capital equipment manufacturers. Geographically, revenue increased from the prior year in most of the Company’s worldwide regions, but most significantly in Japan, where many of the Company’s customers who are capital equipment manufacturers are located.

Product revenue for the three-month and six-month periods ended July 4, 2004 totaled $47,960,000 and $90,520,000, respectively, compared to $31,391,000 and $59,639,000 for the same periods in 2003, representing a 53% increase for the three-month period and a 52% increase for the six-month period. The increase in product revenue was primarily due to a higher volume of machine vision systems sold to customers in the semiconductor and electronics industries. Service revenue, which is derived from the sale of maintenance and support, education, consulting, and installation services, totaled $6,507,000 and $12,116,000 for the three-month and six-month periods ended July 4, 2004, respectively, compared to $5,231,000 and $9,871,000 for the same periods in 2003, representing a 24% increase for the three-month period and a 23% increase for the six-month period. Many of the Company’s products that were sold during 2003 included bundled maintenance and support programs for which a portion of the revenue will be recognized in future quarters over the program period. As a result, service revenue did not increase at the same rate as product revenue, and it decreased as a percentage of total revenue to 12% for the three-month and six-month periods ended July 4, 2004 compared to 14% for the same periods in 2003.

MVSD revenue for the three-month and six-month periods ended July 4, 2004 totaled $46,450,000 and $88,721,000, respectively, compared to $29,183,000 and $55,812,000 for the same periods in 2003, representing a 59% increase for both periods. The increase in MVSD revenue was primarily due to a higher volume of systems sold to customers in the semiconductor and electronics industries. SISD revenue for the three-month and six-month periods ended July 4, 2004 totaled $8,017,000 and $13,915,000, respectively, compared to $7,439,000 and $13,698,000 for the same periods in 2003, representing a 8% increase for the three-month period and a 2% increase for the six-month period. The increase in SISD revenue was due principally to a higher volume of SmartView® system sales. SISD revenue decreased as a percentage of total revenue to 15% and 14% for the three-month and six-month periods ended July 4, 2004, respectively, compared to 20% for the same periods in 2003 due to the significant increase in sales to capital equipment manufacturers at MVSD.

Gross Margin

Gross margin as a percentage of revenue was 71% and 70% for the three-month and six-month periods ended July 4, 2004, respectively, compared to 67% and 66% for the same periods in 2003. The increase in gross margin was primarily due to the impact of the higher sales volume, as well as a greater percentage of total revenue from the sale of modular vision systems, which carry higher margins than the sale of services and surface inspection systems.

Product gross margin as a percentage of revenue was 74% for both the three-month and six-month periods ended July 4, 2004 compared to 71% and 70% for the same periods in 2003. The increase in product margin was due primarily to the increased sales volume, as well as the shift in product mix to higher-margin modular vision systems. Service gross margin as a percentage of revenue was 45% and 42% for the three-month and six-month periods ended July 4, 2004, respectively, compared to 43% and 41% for the same periods in 2003. The increase in service margin was due principally to higher maintenance and support revenue that is sold bundled with MVSD products.

MVSD gross margin as a percentage of revenue was 75% and 74% for the three-month and six-month periods ended July 4, 2004, respectively, compared to 71% and 70% for the same periods in 2003. The increase in MVSD margin was primarily due to the higher sales volume of modular vision systems. SISD gross margin as a percentage of revenue was 46% and 47% for the three-month and six-month periods ended July 4, 2004, respectively, compared to 51% and 49% for the same periods in 2003. The decrease in SISD margin was due principally to higher service costs required to grow the worldwide support organization.

Operating Expenses

Research, development, and engineering expenses (R,D&E) for the three-month and six-month periods ended July 4, 2004 were $6,655,000 and $13,553,000, respectively, compared to $6,263,000 and $12,246,000 for the same periods in 2003, representing a 6% increase for the three-month period and a 11% increase for the six-month period. MVSD R,D&E expenses for the three-month and six-month periods ended July 4, 2004 increased 9% and 13%, respectively, from the same periods in 2003. The increase for the three-month period was primarily due to the accrual of anticipated company bonuses for 2004. The increase for the six-month period was principally due to higher personnel-related costs, including the accrual of anticipated company bonuses for 2004 and additional engineering personnel resulting from the acquisition of the machine vision business of Gavitec AG on December 1, 2003. SISD R,D&E expenses for the three-month and six-month periods ended July 4, 2004 decreased 12% and 7%, respectively, from the same periods in 2003 principally due to lower spending on software translation services and other activities related to the SmartView® product line.

Selling, general, and administrative (S,G&A) expenses for the three-month and six-month periods ended July 4, 2004 were $17,568,000 and $33,882,000, respectively, compared to $13,949,000 and $27,193,000 for the same periods in 2003, representing a 26% increase for the three-month period and a 25% increase for the six-month period. MVSD S,G&A expenses for the three-month and six-month periods ended July 4, 2004 increased 25% from the same periods in 2003, while SISD S,G&A expenses increased 18% for the three-month period and 17% for the six-month period. Corporate expenses that are not allocated to a division increased 46% for the three-month period and 28% for the six-month period. The increase in MVSD and SISD expenses was primarily due to higher personnel-related costs, including commissions related to the higher sales volume, additional end-user sales personnel, and the accrual of anticipated company bonuses for 2004, as well as the unfavorable impact of foreign exchange rate changes on the Company’s international operations. The increase in corporate expenses was due principally to the accrual of anticipated company bonuses for 2004.

Foreign Currency Gain (Loss)

During the three-month and six-month periods ended July 4, 2004, the Company recorded foreign currency losses of $50,000 and gains of $575,000, respectively, compared to losses of $1,164,000 and $1,791,000 for the same periods in 2003. These gains and losses primarily arose from the revaluation and settlement of accounts receivable denominated in currencies other than the subsidiary’s functional currency, as well as the revaluation of intercompany balances that were not fully hedged.

Investment and Other Income

Investment and other income for the three-month and six-month periods ended July 4, 2004 totaled $1,031,000 and $2,305,000, respectively, compared to $1,615,000 and $2,909,000 for the same periods in 2003. The decrease in investment and other income was primarily due to lower average interest rates on the Company’s invested balances.

Income Taxes

The Company’s effective tax rate for the three-month and six-month periods ended July 4, 2004 was 29% compared to 32% for the same periods in 2003. The decrease in the effective tax rate was due primarily to more of the Company’s profits being earned and taxed in lower tax jurisdictions.

Liquidity and Capital Resources

At July 4, 2004, the Company’s cash, cash equivalent, and investment balances increased $57,737,000 to $361,239,000 from $303,502,000 at December 31, 2003. The Company’s cash requirements during the six-month period ended July 4, 2004 were met with positive cash flow from operations, as well as the proceeds from the issuance of common stock under stock option plans that totaled $40,528,000. Cash requirements consisted of operating activities, capital expenditures, and the payment of dividends. Capital expenditures during the six-month period ended July 4, 2004 totaled $1,261,000 and consisted principally of expenditures for computer hardware and software.

The commitment to contribute capital expires on January 1, 2005, and the Company does not have the right to withdraw from the partnership prior to December 31, 2010.

On March 31, 2003, the Company acquired the wafer identification business of Siemens Dematic AG for a net purchase price of 6,204,000 Euros in cash (or approximately $6,762,000), with the potential for an additional cash payment in 2005 of up to 1,700,000 Euros (or approximately $2,068,000) depending upon the achievement of certain performance criteria.

There is the potential for an additional cash payment of up to 250,000 Euros in both 2004 and 2005 (or approximately $304,000 in each year) depending upon the achievement of certain performance criteria.

On December 12, 2000, the Company’s Board of Directors authorized the repurchase of up to $100,000,000 of the Company’s common stock. During 2002, a total of 1,768,452 shares were repurchased at a cost of $26,425,000. There have been no other shares repurchased under this program. The Company may repurchase additional shares under this program in future periods depending upon a variety of factors, including the market value of the Company’s common stock and the average return on the Company’s invested balances.

On April 22, 2004, the Company’s Board of Directors declared a cash dividend of $0.06 per share. The dividend, amounting to $2,714,000, was paid on May 21, 2004 to all stockholders of record at the close of business on May 7, 2004. On July 22, 2004, the Company’s Board of Directors declared a cash dividend of $0.08 per share payable on August 20, 2004 to all stockholders of record at the close of business on August 6, 2004. Future dividends will be declared at the discretion of the Board of Directors and will depend upon such factors as the Board of Directors deems relevant. The Board of Directors may modify the Company’s dividend policy from time to time.

The Company believes that its existing cash, cash equivalents, and investment balances, together with cash flow from operations, will be sufficient to meet its operating, investing, and financing activities in 2004, as well as for the next few years.
