1.    Basis of Presentation

        The accompanying condensed consolidated financial statements have been prepared by TTM Technologies, Inc. (the "Company"), without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations. These condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments), which in the opinion of management, are necessary to present fairly the financial position, the results of operations and cash flows of the Company for the periods presented. It is suggested that these condensed consolidated financial statements be read in conjunction with the consolidated financial statements and the notes thereto included in the Company's Annual Report to Shareholders on Form 10-K.

        The results of operations for the interim periods are not necessarily indicative of the results to be expected for the full year.

2.    Earnings (Loss) Per Common Share

        The following is a reconciliation of the numerator and denominator used to calculate basic earnings per common share and diluted earnings per common share for the quarter and three quarters ended September 30, 2002, and October 1, 2001:

        The computation of Diluted EPS does not assume exercise or conversion of securities that would have an antidilutive effect on net income per common share. As of September 30, 2002, stock options to purchase 2,533 shares of common stock were not considered for loss periods since their effect would be antidilutive, thereby decreasing the loss for common shares. As of October 1, 2001, options to purchase 451 shares of common stock were not included in the computation of Diluted EPS because the exercise prices of the options were greater than the average market price of the common shares during the third fiscal quarter 2001.

3.    Common Stock Transactions

        The Company completed a secondary offering in February 2002 in which a total, including the overallotment option, of 7,245 shares of common stock were sold (2,025 were sold by the Company and 5,220 shares were sold by the selling shareholders) at a price of $8.50 per share. The Company received net proceeds of approximately $15,283 after the underwriting discounts of $0.446 per share and other secondary offering expenses of approximately $1,027, which includes a $258 financial advisory fee paid to T.C. Management Partners IV, L.L.C. and Brockway Moran & Partners Management, L.P., entities owned by certain of our shareholders.

        During the three fiscal quarters ended September 30, 2002, the Company issued options to purchase 266 shares of common stock at a weighted-average exercise price of $9.84 per share.

        During the three fiscal quarters ended September 30, 2002, employees exercised stock options to purchase 179 shares of common stock at $2.63 per share for total proceeds of $471. The Company recorded a tax benefit of $189 as an increase to common stock for certain nonqualified options that were exercised during the same quarters.

        At September 30, 2002, there were outstanding options to purchase 2,533 shares of common stock with a weighted average price of $5.86.

4.    Goodwill and Other Intangible Assets

        Effective January 1, 2002, the Company adopted FASB Statement No. 142, "Goodwill and Other Intangible Assets." FASB No. 142 requires that goodwill and intangible assets deemed to have indefinite lives are no longer amortized but subject to assessment for impairment by applying a fair-valued-based impairment test in accordance with the statement. Other intangible assets will continue to be amortized over their useful lives. Upon adoption during the first quarter of 2002, the Company performed the required impairment tests of goodwill and determined that no impairment had occurred.

        As of September 30, 2002, the Company had goodwill with a carrying value of $63,153 which is not being amortized and is subject to impairment testing. The Company performs a goodwill impairment test on an annual basis or more often, if events or changes in circumstances indicate that impairment may exist. The Company plans to perform its annual impairment test no later than the first quarter of 2003. It is possible that the test could result in an impairment charge which could have an adverse impact on the Company's profitability and results of operations.

        The following is a reconciliation of net income (loss) and earnings (loss) per share adjusted to show the impact of eliminating goodwill amortization and the related income tax effect as if FASB No. 142 had been in place during the quarter and three quarters ended October 1, 2001:

5.    Restructuring charges

        The Company recorded $907 in pretax restructuring charges for labor force reduction at its Burlington facility during the second quarter ended July 1, 2002. The charges consist of primarily severance costs for 141 terminated employees. All terminated employees were notified in June 2002. As of September 30, 2002, all restructuring accrual amounts were paid.

        Subsequent to quarter end, the Company announced its plans to consolidate manufacturing capabilities by closing its Burlington facility by the end of 2002. The Company expects to record significant restructuring charges in the fourth quarter of 2002. Although the assessment of the exact breakdown of the restructuring charges has not been finalized, the Company expects a substantial impairment charge related to the building, property and equipment at the Burlington facility and restructuring charges associated with the elimination of 51 employees at the facility.

6.    Legal Matters

        From time to time the Company may become a party to various legal proceedings arising in the ordinary course of our business. The Company was recently advised that it has been added as a defendant in a patent infringement lawsuit filed in the U.S. District Court for the District of Arizona by Lemelson Medical, Education and Research Foundation, Limited Partnership. The suit alleges that the Company infringed certain "machine vision" and other patents owned by the plaintiff and seeks injunctive relief, damages for the alleged infringements and payment of the plaintiff's attorneys' fees. Although the ultimate outcome of this matter is not currently determinable, the Company believes it has meritorious defenses to these allegations and, based in part on the licensing terms offered by the Lemelson Partnership, does not expect this litigation to materially impact the Company's business, results of operations or financial condition. However, there can be no assurance that the ultimate resolution of this matter will not have a material adverse effect. Furthermore, there can be no assurance that the Company will prevail in any such litigation.

Item 2.  Management's Discussion and Analysis of Financial Condition and Results of Operations

        The following discussion of our financial condition and results of operations should be read in conjunction with our condensed consolidated financial statements and the related notes and the other financial information included in this Quarterly Report on Form 10-Q. This discussion and analysis contains forward-looking statements that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of specified factors, including those set forth in the section below entitled "Factors That May Affect Future Results" and elsewhere in this Quarterly Report on Form 10-Q.

        This discussion and analysis should be read in conjunction with "Management's Discussion and Analysis of Financial Condition and Results of Operations" set forth in our annual report on Form 10-K for the fiscal year ended December 31, 2001, filed with the Securities and Exchange Commission.

OVERVIEW

        We provide time-critical, one-stop manufacturing services for highly complex printed circuit boards. Our customers include original equipment manufacturers of electronic products and their suppliers, or electronic manufacturing services providers. Our time-to-market focused manufacturing services enable our customers to shorten the time required to develop new products and bring them to market.

        We support a strong and diversified customer base. We measure customers as those companies that place at least two orders in a 12-month period. As of September 30, 2002, we had approximately 560 customers, compared to approximately 620 customers as of October 1, 2001. We added 31 new customers in the third fiscal quarter 2002. Sales to our top 10 customers decreased from 53.0% of our net sales for the third fiscal quarter 2001 to 40.0% of our net sales for the third fiscal quarter 2002.

        The following table shows the percentage of our net sales in each of the principal end markets we served for the periods indicated:

        Our products are manufactured to our customers' design specifications and are priced to reflect both the complexity of the printed circuit boards and the time and volume requirements for the order. Generally, we quote prices after we receive the design specifications and time and volume requirements from our customers. Purchase orders may be cancelled prior to shipment. We charge customers a fee, based on percentage completed, if an order is cancelled once it has entered production.

        We recognize revenues upon shipment to the customer. We record net sales as our gross sales less an allowance for returns. We provide our customers a limited right of return for defective printed circuit boards. We record an allowance for estimated sales returns at the time of sale based on our historical results.

        Cost of goods sold consists of materials, labor, outside services and overhead expenses incurred in the manufacture and testing of our products. Many factors affect our gross margin, including capacity utilization, product mix, production volume and yield. We do not participate in any significant long-term supply contracts, and we believe there are a number of potential suppliers for the raw materials we use. We believe that our cost of goods sold will continue to fluctuate as a percentage of net sales.

10

        Selling and marketing expenses consist primarily of salaries and commissions paid to our internal sales force and commissions paid to independent sales representatives, as well as costs associated with marketing materials and trade shows. As quick-turn sales become a higher percentage of total sales, our average commission rate is expected to increase. We expect our selling and marketing expenses to continue to fluctuate as a percentage of net sales.

        General and administrative costs primarily include the salaries for executive, finance, accounting, facilities and human resources personnel, as well as insurance expenses and expenses for accounting and legal assistance. We expect these expenses to continue to fluctuate as a percentage of net sales as we add personnel and incur additional costs related to the growth of our business and the requirements of operating as a public company.

        Amortization of intangibles consists of intangible assets, which we recorded as a result of the Power Circuits acquisition in July 1999. Effective January 1, 2002, we no longer record amortization on goodwill (see "Recently Issued Accounting Standards"). However, we will continue to amortize our intangible assets, which are primarily comprised of definite-lived strategic customer relationships.

        Our interest expense relates to our senior credit facility and our other long-term obligations.

        Amortization of debt issuance costs consists of the amortization of loan origination fees and related expenses. Interest and other income consists primarily of interest received on our cash balances.

Significant Accounting Policies—Significant Judgments and Estimates

        Accounting policies where significant judgments and estimates are made include: asset valuation related to bad debts; sales returns and allowances; impairment of long-lived assets, including goodwill and intangible assets; and realizability of deferred tax assets. A detailed description of these estimates and our policies to account for them is included in the notes to our consolidated financial statements in our annual report on Form 10-K. Our estimates are based on historical experience as well as relevant facts and circumstances known to us at each reporting date. Actual results may differ from these estimates.

        We provide customary credit terms to our customers and generally do not require collateral. We perform ongoing credit evaluations of the financial condition of our customers and maintain an allowance for doubtful accounts based upon historical collections experience and expected collectibility of accounts. Our actual bad debts may differ from our estimates.

        We derive revenues primarily from the sale of PCBs using customer supplied engineering and design plans and recognizes revenues when products are shipped to the customer. We provide our customers a limited right of return for defective PCBs. We accrue an estimated amount for sales returns and allowances at the time of sale based on historical information. To the extent actual returns for defective PCBs vary from our historical experience, revisions to the allowances may be required.

        Long-lived assets, including definite-lived intangibles, are reviewed for impairment whenever events or changes in circumstances indicate that the book value of the asset may not be recoverable. Our long-lived assets consist of property, plant and equipment and strategic customer relationship intangible assets. We evaluate, at each reporting date, whether events and circumstances have occurred that indicate possible impairment. We use an estimate of the future undiscounted net cash flows of the related asset over the remaining life in measuring whether the assets are recoverable. Measurement of the amount of impairment, is based upon the difference between the asset's carrying value and fair value. Any such impairment charge could be significant and could have a material adverse effect on our financial statements if and when an impairment charge is recorded. In connection with our recently announced restructuring activities, we expect to record a significant impairment charge in the fourth quarter of 2002 related to the closure of our Burlington facility (see "Results of Operations").

        As of September 30, 2002, we have goodwill with a carrying value of $63.2 million which is not being amortized and is subject to impairment testing. We perform a goodwill impairment test on an annual basis or more often, if events or changes in circumstances indicate that impairment may exist. We plan to perform the annual impairment test no later than the first quarter of 2003. It is possible that the test could result in an impairment charge which could have an adverse impact on the Company's profitability and results of operations.

11

        Deferred tax assets are reviewed, for recoverability and valuation allowances are provided, when necessary, to reduce deferred tax assets to the amounts expected to be realized. We have not recorded a valuation allowance at September 30, 2002, because we believe that it is more likely than not that the results of future operations will generate sufficient taxable income to utilize these deferred tax assets. Should our expectations of taxable income change in future periods, it may become necessary to record a valuation allowance which would adversely affect our results of operations in the period such a determination was made. In addition, we record income tax expense or benefit at a rate that is based on expected results for the fiscal year. If future changes in market conditions cause actual results for the year to be more or less favorable than those expected, adjustments to the effective income tax rate could be required.

RESULTS OF OPERATIONS

Third Fiscal Quarter 2002 Compared to the Third Fiscal Quarter 2001

Net Sales

        Net sales decreased $6.3 million, or 23.4%, from $26.9 million for the third fiscal quarter 2001 to $20.6 million for the third fiscal quarter 2002. This decrease resulted primarily from a decline in the volume of printed circuit boards sold and was partially offset by higher pricing levels. Net sales declined due to a significant downturn in the electronics industry and in the end markets served by our customers.

Cost of Goods Sold

        Cost of goods sold decreased $3.3 million, or 15.7%, from $21.0 million for the third fiscal quarter 2001 to $17.7 million for the third fiscal quarter 2002. The decrease in cost of goods sold resulted from lower labor, materials, and variable overhead costs that were associated with a decline in the number of printed circuit board units sold. As a percentage of net sales, cost of goods sold increased from 78.2% for the third fiscal quarter 2001 to 86.2% for the third fiscal quarter 2002. Higher medical expense and an increase in unabsorbed manufacturing overhead due to excess capacity resulted in a higher cost of goods sold percentage.

Gross Profit

        Gross profit decreased $3.0 million, or 50.8%, from $5.9 million for the third fiscal quarter 2001 to $2.9 million for the third fiscal quarter 2002. This decrease in gross profit resulted primarily from a lower volume of printed circuit boards sold. Our gross margin was 13.8% during the third fiscal quarter 2002 compared to 21.8% for the third fiscal quarter 2001. Gross margin decreased due to increased medical expense and lower absorption of fixed manufacturing expenses.

Operating Expenses

        Sales and marketing expenses remained approximately stable at $1.5 million for the third fiscal quarter 2001 and third fiscal quarter 2002. As a percentage of net sales, selling expenses increased from 5.5% for the third fiscal quarter 2001 to 7.5% for the third fiscal quarter 2002. The increase as a percentage of net sales, was due to lower absorption of fixed sales and marketing expenses and higher commissions related to a higher proportion of quick-turn sales.

        General and administrative expenses increased $0.3 million, or 25.0%, from $1.2 million for the third fiscal quarter 2001 to $1.5 million for the third fiscal quarter 2002. This increase resulted from a higher bad debt provision, partially offset by lower labor costs and medical expense. We added to our accounts receivable allowance in the third fiscal quarter 2002 compared to reducing the allowance in the third fiscal quarter 2001. We reduced the accounts receivable allowance in the third fiscal quarter

12

2001 due to an improved trend in collections and the quality of our accounts receivable aging compared to the historical trends experienced in the fiscal year 2000. The quality of our accounts receivable aging in 2002 remains comparable with the improved trends experienced in 2001.

        Amortization of intangibles consists of amortization of goodwill and other intangible assets from the Power Circuits acquisition, which occurred in July 1999. Amortization of intangibles decreased $0.9 million from $1.2 million for the third fiscal quarter 2001 to $0.3 million for the third fiscal quarter 2002. This decrease resulted from our adoption of FASB Statement No. 142, "Goodwill and Other Intangible Assets," effective January 1, 2002. Under the new rules, goodwill and intangible assets deemed to have indefinite lives no longer are amortized. The amortization expense recorded in the third fiscal quarter 2002 was for intangible assets with finite useful lives.

        We recently announced our plans to consolidate manufacturing capabilities by closing our Burlington facility by the end of 2002. We expect to record related restructuring charges between $3.3 million and $3.8 million in the fourth fiscal quarter 2002. Although the assessment of the exact breakdown of the restructuring charges has not been finalized, we expect a substantial impairment charge related to the building, property and equipment at the Burlington facility and restructuring charges associated with the elimination of 51 employees at the facility.

Interest Expense

        Interest expense decreased $0.3 million from $0.6 million for the third fiscal quarter 2001 to $0.3 million for the third fiscal quarter 2002. This decrease resulted from a lower interest rate on our term loan as well as a lower balance due to repayment of principal. The expiration of an interest rate swap agreement on December 31, 2001, also contributed to the decline in interest expense through a reduction in our effective interest rate.

Interest Income and Other, Net

        Interest income and other, net, increased $96,000 from income of $96,000 for the third fiscal quarter 2001 to income of $192,000 for the third fiscal quarter 2002. This increase resulted from higher interest earnings on our higher cash balance.

Income Taxes

        The provision for income taxes decreased from a provision of $0.6 million for the third fiscal quarter 2001 to a benefit of $0.2 million for the third fiscal quarter 2002. This income tax benefit resulted from a pretax net loss. Our effective tax rate for the third fiscal quarter 2002 was approximately 30%, due primarily to the impact of nondeductible items.

First Three Fiscal Quarters 2002 Compared to the First Three Fiscal Quarters 2001

Net Sales

        Net sales decreased $36.0 million, or 34.7%, from $103.6 million for the first three fiscal quarters 2001 to $67.6 million for the first three fiscal quarters 2002. This decrease resulted primarily from a decline in the volume of printed circuit boards sold and lower pricing levels. Net sales declined due to a significant downturn in the electronics industry and in the end markets served by our customers.

Cost of Goods Sold

        Cost of goods sold decreased $11.2 million, or 15.6%, from $71.6 million for the first three fiscal quarters 2001 to $60.4 million for the first three fiscal quarters 2002. The decrease in cost of goods sold resulted from lower labor, materials, and variable overhead costs that were associated with a decline in the number of printed circuit board units sold, partially offset by higher medical and depreciation

13

expense. As a percentage of net sales, cost of goods sold increased from 69.2% for the first three fiscal quarters 2001 to 89.4% for the first three fiscal quarters 2002. Lower pricing, higher medical and depreciation expense, and an increase in unabsorbed manufacturing overhead resulted in a higher cost of goods sold percentage.

Gross Profit

        Gross profit decreased $24.8 million, or 77.7%, from $31.9 million for the first three fiscal quarters 2001 to $7.1 million for the first three fiscal quarters 2002. This decrease in gross profit resulted primarily from a lower volume of printed circuit boards sold and lower pricing levels. Our gross margin was 10.6% during the first three fiscal quarters 2002 compared to 30.8% for the first three fiscal quarters 2001. Gross margin decreased primarily due to lower pricing, increased medical and depreciation expense, and lower absorption of fixed manufacturing expenses.

Operating Expenses

        Sales and marketing expenses decreased $1.1 million from $5.9 million for the first three fiscal quarters 2001 to $4.8 million for the first three fiscal quarters 2002. This decrease resulted primarily from lower sales commissions due to lower net sales. As a percentage of net sales, selling expenses increased from 5.7% for the first three fiscal quarters 2001 to 7.1% for the first three fiscal quarters 2002 due primarily to lower absorption of fixed sales and marketing expenses and higher commissions related to a higher proportion of quick-turn sales.

        General and administrative expenses decreased $1.0 million from $4.1 million for the first three fiscal quarters 2001 to $3.1 million for the first three fiscal quarters 2002. This decrease resulted primarily from lower labor costs, lower incentive compensation provision, and lower medical expense, partially offset by higher bad debt provision.

        Amortization of intangibles consists of amortization of goodwill and other intangible assets from the Power Circuits acquisition, which occurred in July 1999. Amortization of intangibles decreased $2.7 million from $3.6 million for the first three fiscal quarters 2001 to $0.9 million for the first three fiscal quarters 2002. This decrease resulted from our adoption of FASB Statement No. 142, "Goodwill and Other Intangible Assets," effective January 1, 2002. Under the new rules, goodwill and intangible assets deemed to have indefinite lives no longer are amortized. The amortization expense recorded in the first three fiscal quarters 2002 was for intangible assets with finite useful lives.

        Restructuring charges were incurred in the first three fiscal quarters 2002 relating to our Burlington facility. We reduced the facility's labor force by 141 employees and recorded $0.9 million in pretax restructuring charges. The costs were primarily severance costs. As of September 30, 2002, all restructuring accrual amounts were paid.

        We recently announced our plans to consolidate manufacturing capabilities by closing our Burlington facility by the end of 2002. We expect to record related restructuring charges between $3.3 million and $3.8 million in the fourth fiscal quarter 2002. Although the assessment of the exact breakdown of the restructuring charges has not been finalized, we expect a substantial impairment charge related to the building, property and equipment at the Burlington facility and restructuring charges associated with the elimination of 51 employees at the facility.

Interest Expense

        Interest expense decreased $1.3 million from $2.1 million for the first three fiscal quarters 2001 to $0.8 million for the first three fiscal quarters 2002. This decrease resulted from a lower interest rate on our term loan as well as a lower balance due to repayment of principal. The expiration of an interest

14

rate swap agreement on December 31, 2001, also contributed to the decline in interest expense, through a reduction in our effective interest rate.

Interest Income and Other, Net

        Interest income and other, net, decreased $29,000 from income of $529,000 for the first three fiscal quarters 2001 to income of $500,000 for the first three fiscal quarters 2002. This decrease resulted from lower interest earnings due to a declining interest rate in the first three fiscal quarters 2002, and was partially offset by the interest earnings of our higher cash balance during the same period.

Income Taxes

        The provision for income taxes decreased from a provision of $6.1 million for the first three fiscal quarters 2001 to a benefit of $0.9 million for the first three fiscal quarters 2002. This income tax benefit resulted from a pretax net loss. Our effective tax rate for the first three fiscal quarters 2002 was approximately 32%.

Liquidity and Capital Resources

        Our principal sources of liquidity have been cash provided by operations, proceeds from our public offerings and borrowings under debt agreements. Our principal uses of cash have been to finance mergers and acquisitions, meet debt service requirements and finance capital expenditures. We anticipate that these uses will continue to be our principal uses of cash in the future.

        Net cash provided by operating activities was $7.6 million in the first three fiscal quarters 2002, compared to $33.0 million in the first three fiscal quarters 2001. The difference between our net loss in the first three fiscal quarters 2002 of $1.9 million and our $7.6 million operating cash flow was primarily attributable to $7.7 million of depreciation and amortization expense, a decrease of $3.3 million of deferred income taxes, and a decrease of $2.1 million of accounts receivable, partially offset by a $2.6 million decrease in accounts payable, a $0.4 million decrease in accrued expenses and other, and a $0.6 million increase in income taxes receivable.

        Net cash used in investing activities was $6.7 million in the first three fiscal quarters 2002, compared to $10.1 million in the first three fiscal quarters 2001. The decrease in cash used was due to decreased purchases of property, plant and equipment and decreased deposits on property, plant and equipment during the first three fiscal quarters 2002. Included in investing activities for the first three fiscal quarters 2002 is a $3.8 million purchase of a building adjacent to our Redmond facility. This purchase was consummated in the third fiscal quarter 2002. The Company records cash paid for equipment not yet placed in service in a construction-in-process, equipment and other deposits account. When an asset is placed in service, the related amount is transferred from the construction-in-process, equipment and other deposits account to property, plant and equipment.

        Net cash provided by financing activities was $9.8 million in the first three fiscal quarters 2002, compared to net cash used in financing activities of $8.1 million in the first three fiscal quarters 2001. This increase was due to $15.3 million of proceeds from a secondary stock offering as well as $0.4 million of proceeds from stock option exercises during the first three fiscal quarters 2002, partially offset by a principal repayment of $5.9 million on our long-term debt.

        Under our existing senior credit facility, we previously borrowed $45 million under a term loan. The term loan bears interest ranging from LIBOR plus 1% to 2% or the Alternate Base Rate (as defined in the agreement) plus 0% to 0.5% and is due in quarterly payments of various amounts through September 30, 2005. The agreement also provides for a revolving loan commitment for up to $25 million, which bears interest at LIBOR plus 1% to 2% or the Alternate Base rate plus 0% to 0.5% and expires September 29, 2005. As of September 30, 2002, the term loan and the revolving loan had

15

an interest rate of 3.3%. We pay quarterly a commitment fee ranging from 0.30% to 0.45% on the unused revolving commitment amount. The credit facility contains financial covenants customary for this type of financing, and as of September 30, 2002, we were in compliance with the covenants. As of September 30, 2002, the amount outstanding on our term loan was $26.7 million and we had $25 million of availability on our revolving credit facility.

        The following table provides information on future payments under the Company's credit facility and future minimum lease payments under non-cancelable operating leases as of September 30, 2002 (in thousands):

        Based on our current level of operations, we believe that cash generated from operations, available cash and amounts available under our senior credit facility will be adequate to meet the debt service requirements, capital expenditures and working capital needs of our current operations for at least the next 12 months. We may require additional financing if we decide to consummate additional acquisitions. See "Factors That May Affect Future Results."

        On October 14, 2002, our Board of Directors authorized a repurchase of the Company's common stock up to the amount of $10 million. The repurchase of common stock is subject to market conditions and will be accomplished through periodic purchases as prevailing prices on the open market. The repurchased shares will be retired from the Company's total shares issued and outstanding. Through November 5, 2002, we have repurchased 125,500 shares for a total cost of approximately $0.2 million.

Foreign Currency Exchange Risk

        All of our sales are denominated in U.S. dollars, and as a result, we have relatively little exposure to foreign currency exchange risk with respect to sales made.

Impact of Inflation

        We believe that our results of operations are not dependent upon moderate changes in the inflation rate as we expect that we will be able to pass along component price increases to our customers.

Seasonality

        We have historically experienced lower sales in our second and third fiscal quarters due to patterns in the capital budgeting and purchasing cycles of our customers and the end markets they serve. In particular, this effect is caused by the seasonality of our high-end computing segment. We expect to mitigate the impact of seasonality through diversification of our customer base.

Recently Issued Accounting Standards

        In June 2001, the FASB issued Statement No. 141, "Business Combinations," and Statement No. 142, "Goodwill and Other Intangible Assets," effective for the fiscal years beginning after December 15, 2001. Under the new rules, goodwill and intangible assets deemed to have indefinite lives will no longer be amortized but will be subject to annual impairment tests in accordance with the Statements. Other intangible assets will continue to be amortized over their useful lives. We applied the

new rules beginning in the first fiscal quarter 2002. As a result, quarterly goodwill amortization of $902 has ceased effective January 1, 2002. Also upon adoption, we performed the required impairment tests of goodwill and indefinite-lived intangible assets and determined no impairment of goodwill.

        In August 2001, the FASB issued Statement No. 143, "Accounting for Asset Retirement Obligations." This standard requires entities to record the fair value of a liability for an asset retirement obligation in the period in which it is incurred. When the liability is initially recorded, the entity capitalizes a cost by increasing the carrying amount of the related long-lived asset. Over time, the liability is accreted to its present value each period, and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, an entity either settles the obligation for its recorded amount or incurs a gain or loss upon settlement. This standard is effective for fiscal years beginning after June 15, 2002, with earlier application encouraged. We do not believe the adoption of Statement 143 will have a material impact on our consolidated financial statements.

        In October 2001, the FASB issued Statement No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets", which replaces FASB Statement No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." The accounting model for long-lived assets to be disposed of by sale applies to all long-lived assets, including discontinued operations, and replaces the provisions of APB Opinion No. 30, "Reporting Results of Operations-Reporting the Effects of Disposal of a Segment of a Business," for the disposal of segments of a business. Statement 144 requires that those long-lived assets be measured at the lower of carrying amount or fair value less cost to sell, whether reported in continuing operations or in discontinued operations. Therefore, discontinued operations will no longer be measured at net realizable value or include amounts for operating losses that have not yet occurred. Statement 144 also broadens the reporting of discontinued operations to include all components of an entity with operations that can be distinguished from the rest of the entity and that will be eliminated from the ongoing operations of the entity in a disposal transaction. The provisions of Statement 144 are effective for financial statements issued for fiscal years beginning after December 15, 2001, and, generally, are to be applied prospectively. We adopted Statement 144 on January 1, 2002 and there was no impact.

        In July 2002, the FASB issued Statement No. 146 "Accounting for Costs Associated with Exit or Disposal Activities." Under Statement No. 146, a company will record a liability for a cost associated with an exit or disposal activity when that liability is incurred and can be measured at fair value. A liability is incurred when an event obligates the entity to transfer or use assets (i.e., when an event leaves the company little or no discretion to avoid transferring or using the assets in the future). Under previous accounting rules, if a company's management approved an exit plan, the company generally could record the costs of that plan as a liability on the approval date, even if the company did not incur the costs until a later date. Under Statement No. 146, some of those costs might qualify for immediate recognition, others might be spread over one or more quarters, and still others might not be recorded until incurred in a much later period. We are currently reviewing the standard, which is effective for periods after December 31, 2002, and do not expect it to have a significant impact on our results of operations, financial position or liquidity.

Factors That May Affect Future Results

        An investment in our common stock involves a high degree of risk. You should carefully consider the factors described below, in addition to those discussed elsewhere in this report, in analyzing an investment in our common stock. If any of the events described below occurs, our business, financial condition and results of operations would likely suffer, the trading price of our common stock could fall, and you could lose all or part of the money you paid for our common stock.

        In addition, the following factors could cause our actual results to differ materially from those projected in our forward-looking statements, whether made in this 10-Q, our annual or quarterly reports to shareholders, future press releases, SEC filings or orally, whether in presentations, responses to questions or otherwise.

We are heavily dependent upon the electronics industry, which has suffered a significant downturn in demand resulting in excess manufacturing capacity, increased price competition, higher product inventories, decreased demand for our products and lower sales and gross margins.

        A majority of our revenues are generated from the electronics industry, which is characterized by intense competition, relatively short product life cycles and significant fluctuations in product demand. Furthermore, the industry is subject to economic cycles and recessionary periods and has been negatively impacted by a contraction in the U.S. economy. Moreover, due to the uncertainty in the end markets served by most of our customers, we have a low level of visibility with respect to future financial results. A lasting economic recession, continued excess manufacturing capacity or an additional decline in the electronics industry could further negatively impact our business, results of operations and financial condition. Our net sales declined from $46.0 million in the first fiscal quarter 2001 to $30.7 million in the second fiscal quarter 2001, $26.9 million in the third fiscal quarter 2001, $25.4 million in the fourth fiscal quarter 2001, $23.7 million in the first fiscal quarter 2002, $23.3 million in the second fiscal quarter 2002 and $20.6 million in the third fiscal quarter 2002. A continued decline in our net sales would adversely impact our profitability and results of operations and could require us to record a valuation allowance against our deferred tax assets or recognize an impairment of our long-lived assets including goodwill and intangible assets.

If we continue to experience excess capacity due to variability in customer demand, our gross margins may fall.

        Due to recent decreases in demand, our facilities have been operating significantly below capacity. When we experience excess capacity, our sales revenues may be insufficient to fully cover our fixed overhead expenses, and our gross margins will fall. In addition, we generally schedule our quick-turn production facilities at less than full capacity to retain our ability to respond to unexpected additional quick-turn orders. However, if these orders are not made, we may forego some production and could experience continued excess capacity.

We are dependent upon a small number of customers for a large portion of our net sales, and a decline in sales to major customers could harm our results of operations.

        A small number of customers is responsible for a significant portion of our net sales. Our 10 largest customers accounted for 40% of our net sales in the third fiscal quarter 2002. Many of our principal customers have decreased the amount of products they purchase from us. If our customers fail to purchase products from us at past levels, it would negatively affect our business, results of operations and financial condition. We expect a significant portion of our net sales will continue to be generated by a small number of customers.

        Our customer concentration could increase or decrease depending on future customer requirements, which will depend in large part on market conditions in the electronics industry segments in which our customers participate. The loss of one or more major customers or a decline in sales to

18

our major customers could significantly harm our business, results of operations and financial condition and lead to declines in the price of our common stock. In addition, we generate significant accounts receivable in connection with providing services to our customers. If one or more of our significant customers were to become insolvent or were otherwise unable to pay for the services provided by us, our results of operations would be harmed.

If we are unable to respond to rapid technological change and process development, we may not be able to compete effectively.

        The market for our products is characterized by rapidly changing technology and continual implementation of new production processes. The future success of our business will depend in large part upon our ability to maintain and enhance our technological capabilities, to develop and market products that meet changing customer needs and to successfully anticipate or respond to technological changes on a cost-effective and timely basis. We expect that the investment necessary to maintain our technological position will increase as customers make demands for products and services requiring more advanced technology on a quicker turnaround basis. We may not be able to raise additional funds in order to respond to technological changes as quickly as our competitors.

        In addition, the printed circuit board industry could encounter competition from new or revised manufacturing and production technologies that render existing manufacturing and production technology less competitive or obsolete. We may not respond effectively to the technological requirements of the changing market. If we need new technologies and equipment to remain competitive, the development, acquisition and implementation of those technologies and equipment may require us to make significant capital investments.

Competition in the printed circuit board market is intense, and if we are unable to compete effectively, the demand for our products may be reduced.

        The printed circuit board industry is intensely competitive, highly fragmented and rapidly changing. We expect competition to continue, which could result in price reductions, reduced gross margins and loss of market share. Our principal domestic competitors include: DDi, Merix, the Multek subsidiary of Flextronics, Sanmina-SCI and Tyco. In addition, new and emerging technologies may result in new competitors entering our market.

        Many of our competitors and potential competitors have a number of significant advantages over us, including:

•

greater financial and manufacturing resources that can be devoted to the development, production and sale of their products;



•

more established and broader sales and marketing channels;



•

more manufacturing facilities worldwide, some of which are closer in proximity to original equipment manufacturers;



•

manufacturing facilities which are located in countries with lower production costs; and



•

greater name recognition.

        In addition, these competitors may respond more quickly to new or emerging technologies, or may adapt more quickly to changes in customer requirements and may devote greater resources to the development, promotion and sale of their products than we do. We must continually develop improved manufacturing processes to meet our customers' needs for complex products, and our manufacturing process technology is generally not subject to significant proprietary protection. During recessionary periods in the electronics industry, our competitive advantages in the areas of providing quick-turn services, an integrated manufacturing solution and responsive customer service may be of reduced importance to our customers, who may become more price sensitive. This may force us to compete

19

more on the basis of price and cause our margins to decline. Furthermore, printed circuit board manufacturers are currently experiencing significant overcapacity. Overcapacity, combined with the current weakness in demand for electronic products, has resulted in increased competition and price erosion for printed circuit boards.

We compete against manufacturers in Asia where production costs are lower. These competitors may gain market share in our key market segments, which may have an adverse effect on the pricing of our products.

        We may be at a competitive disadvantage with respect to price when compared to manufacturers with lower cost facilities in Asia and other locations. We believe price competition from printed circuit board manufacturers in Asia and other locations with lower production costs may play an increasing role in the market. We do not currently have offshore facilities in lower cost locations, such as Asia. While historically our competitors in these locations have produced less technologically advanced printed circuit boards, they continue to expand their capacity with advanced equipment to produce higher technology printed circuit boards. In addition, fluctuations in foreign currency exchange rates may benefit these offshore competitors. As a result, these competitors may gain market share, which may force us to lower our prices, reducing our gross profit.

Our results of operations are subject to fluctuations and seasonality, and because many of our operating costs are fixed, even small revenue shortfalls would decrease our gross margins and potentially cause our stock price to decline.

        Our results of operations vary for a variety of reasons, including:

•

timing of orders from and shipments to major customers;



•

the levels at which we utilize our manufacturing capacity;



•

changes in the pricing of our products or those of our competitors;



•

changes in our mix of revenues generated from quick-turn versus standard lead time production;



•

expenditures or write-offs related to acquisitions; and



•

expenses relating to expanding existing manufacturing facilities.

        A significant portion of our operating expenses is relatively fixed in nature, and planned expenditures are based in part on anticipated orders. Accordingly, recent revenue shortfalls have decreased our gross margins, and future revenue shortfalls may further decrease our gross margins. In addition, we have experienced sales fluctuations due to patterns in the capital budgeting and purchasing cycles of our customers and the end markets we serve. In particular, the seasonality of the computer industry impacts the overall printed circuit board industry. These seasonal trends have caused fluctuations in our quarterly operating results in the past and may continue to do so in the future. Results of operations in any period should not be considered indicative of the results to be expected for any future period. In addition, our future quarterly operating results may fluctuate and may not meet the expectations of securities analysts or investors. If this occurs, the price of our common stock would likely decline.

Because we sell on a purchase order basis, we are subject to uncertainties and variability in demand by our customers, which could decrease revenues and negatively impact our operating results.

        We sell to customers on a purchase order basis rather than pursuant to long-term contracts, and, consequently, our net sales are subject to short-term variability in demand by our customers. Customers submitting a purchase order may cancel, reduce or delay their order for a variety of reasons. The level and timing of orders placed by our customers vary due to:

•

customer attempts to manage inventory;

20

•

changes in customers' manufacturing strategies, such as a decision by a customer to either diversify or consolidate the number of printed circuit board manufacturers used or to manufacture their own products internally; and



•

variation in demand for our customers' products.

        We have experienced terminations, reductions and delays in our customers' orders. Further terminations, reductions or delays in our customers' orders could negatively impact our business, results of operations and financial condition.

The increasing prominence of electronic manufacturing services providers in the printed circuit board industry could reduce our gross margins, potential sales and customers.

        In the third fiscal quarter 2002, approximately 31% of our net sales were to electronic manufacturing services providers. Electronic manufacturing services providers supply electronic product assembly services to original equipment manufacturers. The growth of electronic manufacturing services providers and their global sourcing capabilities increase the purchasing power of such providers and could result in increased price competition or the loss of existing original equipment manufacturer customers. In addition, in recent years, some electronic manufacturing services providers, including a few of our customers, have acquired the ability to directly manufacture printed circuit boards. If a significant number of our other electronic manufacturing services customers were to acquire the ability to directly manufacture printed circuit boards, our customer base may shrink, and our business and net sales may decline substantially. Moreover, if any of our original equipment manufacturer customers outsource the production of printed circuit boards to these electronic manufacturing services providers, our business, results of operations and financial condition may be negatively impacted.

Our indebtedness could adversely affect our financial health, and the restrictions imposed by the terms of our debt instruments may severely limit our ability to plan for or respond to changes in our business.

        At September 30, 2002, we had approximately $26.7 million of indebtedness. In addition, subject to the restrictions under our various debt agreements, we may incur additional indebtedness from time to time to finance acquisitions or capital expenditures or for other purposes.

        Our level of debt could have negative consequences. For example, it could:

•

require us to dedicate a substantial portion of our cash flow from operations to repayment of debt, limiting the availability of cash for other purposes;



•

increase our vulnerability to adverse general economic conditions by making it more difficult to borrow additional funds to maintain our operations if we suffer revenue shortfalls;



•

hinder our flexibility in planning for, or reacting to, changes in our business and industry by preventing us from borrowing money to upgrade our equipment or facilities; and



•

limit or impair our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions or general corporate purposes.

We may expand our business into new products and services and may not be able to compete effectively with other companies who have been in these businesses longer than we have.

        In the future, we may broaden our service offering by providing new products and services. If we do this, we will likely compete with companies that have substantially greater financial and manufacturing resources than we have and who have been providing these services longer than we have. We may not be able to successfully compete on this basis with more established competitors.

21

In the past, we have expanded our operations through acquisition, and we may have trouble integrating any future acquisitions in expanding our business.

        We may not be able to meet performance expectations or successfully integrate businesses we acquire in the future on a timely basis without disrupting the quality and reliability of service to our customers or diverting management resources.

        To manage the expansion of our operations and any future growth, we will be required to:

•

improve existing and implement new operational, financial and management information controls, reporting systems and procedures;



•

hire, train and manage additional qualified personnel;



•

expand our direct and indirect sales channels; and



•

effectively transition our relationships with our customers, suppliers and partners to operations under our TTM brand.

        As part of our business strategy, we expect that we will continue to grow by pursuing acquisitions, assets or product lines that complement or expand our existing business. We currently have no commitments or agreements to acquire any business. Our existing credit facility restricts our ability to acquire the assets or business of other companies and will accordingly require us to obtain the consent of our lenders and could require us to pay significant fees in order to consummate such acquisitions. Consequently, we may not be able to identify suitable acquisition candidates or to finance and complete transactions that we choose to pursue.

        Our acquisition of companies and businesses and expansion of operations involve risks, including the following:

•

the potential inability to identify the company best suited to our company's business plan;



•

the potential inability to successfully integrate acquired operations and businesses or to realize anticipated synergies, economics of scale or other expected value;



•

difficulties in managing production and coordinating operations at new sites;



•

the potential need to restructure, modify or terminate customer relationships of the acquired company; and



•

loss of key employees of acquired operations.

        In addition, future acquisitions may result in dilutive issuances of equity securities, the incurrence of additional debt, large one-time write-offs and the creation of goodwill or other intangible assets that could result in amortization expense.

If we were to increase our amortization of definite-lived intangible assets as a result of additional acquisitions, our earnings could be negatively impacted. Similarly, if we were to revalue our existing intangible assets downward, our operating results would be harmed.

        As of September 30, 2002, our consolidated balance sheet reflected $77.3 million of intangible assets, a substantial portion of our total assets at such date. Intangible assets consist of goodwill and other identifiable intangibles relating to our July 1999 acquisition of Power Circuits. Our intangible assets may increase in future periods if we consummate other acquisitions. Amortization or impairment of these additional intangibles would, in turn, have a negative impact on earnings. In addition, we continuously evaluate whether events and circumstances have occurred that indicate the remaining balance of intangible assets may not be recoverable. When factors indicate that assets should be evaluated for possible impairment, we may be required to reduce the carrying value of our intangible assets, which could harm our results during the periods in which such a reduction is recognized.

22

        In connection with our adoption of Statement of Financial Accounting Standards No. 142 in the first quarter of 2002, our impairment testing methodology changed, and we may be required to write down intangible assets in future periods. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Recently Issued Accounting Standards."

We rely on suppliers for the raw materials used in manufacturing our printed circuit boards, and an increase in industry demand or the presence of a shortage for these raw materials may increase the price of these raw materials and reduce our gross margins.

        To manufacture our printed circuit boards, we use raw materials such as laminated layers of fiberglass, copper foil and chemical solutions which we order from our suppliers. Although we have preferred suppliers for most of our raw materials, the materials we use are generally readily available in the open market, and numerous other potential suppliers exist. However, from time to time manufacturers of products that also use these raw materials increase their demand for these materials and, as a result, the prices of these materials increase. During these periods of increased demand, our gross margins may decrease as we have to pay more for our raw materials.

Our manufacturing process depends on the collective industry experience of our employees in our industry. If these employees were to leave us and take this knowledge with them, our manufacturing process may suffer and we may not be able to compete effectively.

        We have no patent or trade secret protection for our manufacturing process, but instead rely on the collective experience of our employees in the manufacturing process to ensure we continuously evaluate and adopt new technologies in our industry. Although we are not dependent on any one employee or a small number of employees, if a significant number of our employees involved in our manufacturing process were to leave our employment and we were not able to replace these people with new employees with comparable experience, our manufacturing process may suffer as we may be unable to keep up with innovations in the industry. As a result, we may not be able to continue to compete effectively.

We may be exposed to intellectual property infringement claims by third parties which could be costly to defend, could divert management's attention and resources and, if successful, could result in liability.

        We could be subject to legal proceedings and claims for alleged infringement by us of third party proprietary rights, such as patents, from time to time in the ordinary course of business. For example, in the past we were informed that our prior use of a chemical solution in our manufacturing process may have infringed upon the intellectual property rights of the holder of the patent of the chemical solution. Although no legal action has been taken against us, any claims relating to this alleged infringement, even if not meritorious, could result in costly litigation and divert management's attention and resources. In addition, if we are unsuccessful in disputing this assertion, we could be required to pay royalties or damages for our past use of the chemical solution. Similarly, we were recently advised that we have been added as a defendant in a patent infringement lawsuit filed in the U.S. District Court for the District of Arizona by Lemelson Medical, Education and Research Foundation, Limited Partnership. The suit alleges that we have infringed certain "machine vision" and other patents owned by the plaintiff and seeks injunctive relief, damages for the alleged infringements and payment of the plaintiff's attorneys' fees. If we do not prevail in any litigation as a result of such allegations, our business may be harmed.

If the public confuses us with similarly named companies, our business could suffer.

        It is possible that other companies will adopt trade names similar to ours which would impede our ability to build brand identity and possibly lead to customer confusion. Although we have applied for trademark protection of TTM Technologies, we have not yet received this trademark protection. We are aware of another company using "TTM Technologies" as part of its corporate name. This may cause

23

confusion as to the source, quality and dependability of our product which may, in turn, dilute our brand name and harm our reputation.

Our business may suffer if any of our key senior executives discontinues employment with us or if we are unable to recruit and retain highly skilled engineering and sales staff.

        Our future success depends to a large extent on the services of our key managerial employees, particularly Kenton Alder, our chief executive officer. Although we have entered into employment agreements with Mr. Alder and two other executive officers, we may not be able to retain our executive officers and key personnel or attract additional qualified management in the future. Our business also depends on our continuing ability to recruit, train and retain highly qualified employees, particularly engineering and sales and marketing personnel. The competition for these employees is intense, and the loss of these employees could harm our business. Further, our ability to successfully integrate acquired companies depends in part on our ability to retain key management and existing employees at the time of the acquisition.

Products we manufacture may contain design or manufacturing defects, which could result in reduced demand for our services and liability claims against us.

        We manufacture products to our customers' specifications, which are highly complex and may contain design or manufacturing errors or failures despite our quality control and quality assurance efforts. Defects in the products we manufacture, whether caused by a design, manufacturing or materials failure or error, may result in delayed shipments, customer dissatisfaction, or a reduction or cancellation of purchase orders. If these defects occur either in large quantities or too frequently, our business reputation may be impaired. Since our products are used in products that are integral to our customers' businesses, errors, defects or other performance problems could result in financial or other damages to our customers, for which we may be liable. Although our invoices generally contain provisions designed to limit our exposure to product liability claims, existing or future laws or unfavorable judicial decisions could negate these limitation of liability provisions. Product liability litigation against us, even if it were unsuccessful, would be time consuming and costly to defend.

Our failure to comply with the requirements of environmental laws could result in fines and revocation of permits necessary to our manufacturing processes.

        Our operations are regulated under a number of federal, state and foreign environmental and safety laws and regulations that govern, among other things, the discharge of hazardous materials into the air and water, as well as the handling, storage and disposal of such materials. These laws and regulations include the Clean Air Act, the Clean Water Act, the Resource Conservation and Recovery Act, and the Comprehensive Environmental Response, Compensation and Liability Act, as well as analogous state and foreign laws. Compliance with these environmental laws is a major consideration for us because our manufacturing processes use and generate materials classified as hazardous such as ammoniacal etching solutions, copper and nickel. For example, we incur additional expense at our Burlington facility to transport and treat certain of our waste water discharges because of limitations in the local municipal waste treatment facility. In addition, because we use hazardous materials and generate hazardous wastes in our manufacturing processes, we may be subject to potential financial liability for costs associated with the investigation and remediation of our own sites, or sites at which we have arranged for the disposal of hazardous wastes, if such sites become contaminated. Even if we fully comply with applicable environmental laws and are not directly at fault for the contamination, we may still be liable. The wastes we generate include spent ammoniacal etching solutions, metal stripping solutions and hydrochloric acid solution containing palladium; waste water which contains heavy metals, acids, cleaners and conditioners; and filter cake from equipment used for on-site waste treatment. We believe that our operations substantially comply with all applicable environmental laws. However, any material violations of environmental laws by us could subject us to revocation of our effluent discharge permits. Any such revocations could require us to cease or limit production at one or more of our

24

facilities, negatively impacting our business, results of operations and financial condition. Even if we ultimately prevail, environmental lawsuits against us would be time consuming and costly to defend.

        Environmental laws could also become more stringent over time, imposing greater compliance costs and increasing risks and penalties associated with violation. We operate in environmentally sensitive locations and we are subject to potentially conflicting and changing regulatory agendas of political, business and environmental groups. Changes or restrictions on discharge limits, emissions levels, material storage, handling or disposal might require a high level of unplanned capital investment and/or relocation. It is possible that environmental compliance costs and penalties from new or existing regulations may harm our business, results of operations and financial condition.

Our major shareholder has significant influence over our business and could delay, deter or prevent a change of control or other business combination.

        As of September 30, 2002, Circuit Holdings held approximately 39.3% of our outstanding stock. Thayer Capital Partners controls three entities that together own approximately 60.0% of Circuit Holdings and beneficially own approximately 45.8% of our shares. In addition, two of our directors are representatives of Thayer Capital Partners. Although Thayer Capital does not currently own any interests in our direct competitors, the interests of Thayer Capital Partners may not always coincide with our interests or those of our other shareholders, particularly if Thayer Capital decided to sell its controlling interest in us. By virtue of its stock ownership and board representation, Thayer Capital Partners will continue to have a significant influence over all matters submitted to our board and our shareholders, including the election of our directors, and will be able to exercise significant control over our business, policies and affairs. Through its voting power, Thayer Capital Partners could cause us to take actions that we would not consider absent its influence, or could delay, deter or prevent a change of control of our company or other business combination that might otherwise be beneficial to our public shareholders.

        In addition, Thayer Capital Partners has historically worked closely with Brockway Moran & Partners, Inc. Brockway Moran & Partners Fund, L.P. owns the remaining 40% of Circuit Holdings. In addition, one of our directors is a representative of Brockway Moran & Partners. Although there is no legal agreement requiring Thayer Capital Partners and Brockway Moran & Partners to vote their shares together or for their representatives on our board to vote together, given their relationship in the past these two entities may continue to work together, in which case they would control our board and exercise voting control over approximately 47.9% of our shares that are beneficially owned by such entities.

Item 3.    Quantitative and Qualitative Disclosures About Market Risk

        Interest Rate Risk.    Our senior credit facility bears interest at floating rates.

        The revolving loan bears interest ranging from 1% to 2% per annum plus the applicable LIBOR or from 0% to 0.5% per annum plus the Alternate Base Rate, as defined in the agreement governing the amended and restated credit facility. As of September 30, 2002, the term and revolving term loan had an interest rate of 3.3%. Therefore, a 10% change in interest rates is not expected to materially affect the interest expense to be incurred on this facility during such period.

Item 4.    Controls and Procedures

        As required by Rule 13a-15 under the Exchange Act, within the 90 days prior to the filing date of this report, the Company carried out an evaluation of the effectiveness of the design and operation of the Company's disclosure controls and procedures. This evaluation was carried out under the supervision and with the participation of the Company's management, including the Company's Chief Executive Officer and Chief Financial Officer. Based upon that evaluation, the Company's Chief

25

Executive Officer and Chief Financial Officer concluded that the Company's disclosure controls and procedures are effective. There have been no significant changes in the Company's internal controls or in other factors that could significantly affect internal controls subsequent to the date the Company carried out its evaluation.

        Disclosure controls and procedures are controls and other procedures that are designed to ensure that information required to be disclosed in Company reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms. Disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed in Company reports filed under the Exchange Act is accumulated and communicated to management, including the Company's Chief Executive Officer and Chief Financial Officer as appropriate, to allow timely decisions regarding required disclosure.

26

PART II. OTHER INFORMATION

Item 1.    Legal Proceedings

        From time to time we may become a party to various legal proceedings arising in the ordinary course of our business. We were recently advised that we have been added as a defendant in a patent infringement lawsuit filed in the U.S. District Court for the District of Arizona by Lemelson Medical, Education and Research Foundation, Limited Partnership. The suit alleges that we have infringed certain "machine vision" and other patents owned by the plaintiff and seeks injunctive relief, damages for the alleged infringements and payment of the plaintiff's attorneys' fees. Although the ultimate outcome of this matter is not currently determinable, we believe we have meritorious defenses to these allegations and, based in part on the licensing terms offered by the Lemelson Partnership, do not expect this litigation to materially impact our business, results of operations or financial condition. However, there can be no assurance that the ultimate resolution of this matter will not have a material adverse effect on our results of operations for any quarter. Furthermore, there can be no assurance that we will prevail in any such litigation.
