SUMMARY

    You should read the following summary together with the more detailed information in this prospectus, including risk factors, regarding our company and the common stock being sold in this offering.

Our Company

    TTM Technologies, Inc. provides time-critical, one-stop manufacturing services for highly complex printed circuit boards, which serve as the foundation of electronic products such as communications infrastructure equipment, industrial and medical equipment and servers. Our customers include manufacturers of these electronic products, commonly referred to as original equipment manufacturers, and the electronic manufacturing services companies which supply them. Products within the markets we serve have high levels of complexity and short life cycles as manufacturers continually develop new and increasingly sophisticated technology. Our name, TTM, stands for "time-to-market" because our services enable our customers to shorten the time required to develop new products and bring them to market.

    We provide our customers with a manufacturing solution that encompasses all stages of an electronic product's life cycle. We utilize a facility specialization strategy in which we place each order in the facility best suited for the customer's particular delivery time and volume needs. These facilities use compatible technologies and manufacturing processes, allowing us to optimize our manufacturing operations and efficiently move orders among facilities. This strategy results in faster delivery times and enhanced product quality and consistency.

    Our one-stop manufacturing solution includes quick-turn and standard delivery time services:

Quick-turn services:

    We refer to our rapid turnaround services as "quick-turn" because we provide custom-designed printed circuit boards to our customers in as little as 24 hours.

•

Prototype production. In the design, testing and launch phase of a new electronic product's life cycle, our customers typically require limited quantities of printed circuit boards in a very short period of time. We satisfy this need by manufacturing prototype printed circuit boards in quantities of up to 50 boards per order with delivery times ranging from as little as 24 hours to 10 days.



•

Ramp-to-volume production. After a product has successfully completed the prototype phase, our customers introduce the product to the market and require larger quantities of printed circuit boards in a short period of time. This transition stage between low-volume prototype production and mid-volume production is known as ramp-to-volume. Our ramp-to-volume services typically include manufacturing up to several hundred printed circuit boards per order with delivery times ranging from two to 10 days.

    For the year ended December 31, 2000 and the first three quarters of 2001, orders with delivery requirements of 10 days or less represented 35% and 41% of our gross sales, respectively. Ten day or less orders represented a significantly higher percentage of gross sales for our Santa Ana facility, which focuses on prototype production and new customer development.

Standard delivery time services:

•

Mid-volume production. Following market introduction, a product proceeds to commercial production in larger quantities with typical industry delivery times of several weeks. Our mid-volume production services include manufacturing up to several hundred printed circuit boards per order with delivery times ranging from three to eight weeks.

1

    Our quick-turn services provide us with the opportunity to develop relationships with customers using our prototype and ramp-to-volume services and to extend these relationships to include mid-volume production services. During our involvement in the early stages of product development, we can introduce customers to our advanced manufacturing processes and technology expertise, thereby increasing our ability to capture our customers' higher complexity mid-volume production business.

    Key aspects of our solution include:

•

Time-to-market focused services: We deliver highly complex printed circuit boards to customers in as little as 24 hours. This rapid delivery service enables original equipment manufacturers to develop sophisticated electronic products quickly and shorten the products' time-to-market introduction;



•

Strong process and technology expertise: We deliver time-critical, highly complex manufacturing services through our manufacturing process and technology expertise. In 2000 and the first three quarters of 2001, 57% and 63%, respectively, of our gross sales involved the manufacture of printed circuit boards with at least eight layers, an industry accepted measure of complexity. In addition, many of our lower layer count boards are complex as a result of the incorporation of other technologically advanced features; and



•

One-stop manufacturing solution: We provide a one-stop manufacturing solution to our customers through our specialized facilities, each of which focuses on a different stage of an electronic product's life cycle.

    We provide our time-to-market services primarily to customers whose products are subject to continuous technological innovation and numerous product improvements. Our significant original equipment manufacturer customers include Ciena, Compaq, General Electric, Motorola, Philips Ultrasound and Radisys. Our significant electronic manufacturing services customers include Celestica, Flextronics, Plexus, Sanmina-SCI, Solectron and Viasystems. As of October 1, 2001, we had approximately 620 customers, compared to approximately 550 customers at December 31, 2000.

Our Strategy

    Our goal is to be the leading provider of technologically advanced, time-critical, one-stop manufacturing services for highly complex printed circuit boards. Key aspects of our strategy include:

•

using our quick-turn capabilities to target customers in high-growth markets;



•

aggressively managing our manufacturing capacity to maximize profitability while continuing to serve our customers' demands and meet the requirements of new customers;



•

capitalizing on our one-stop manufacturing solution to capture additional business from customers throughout different stages of the product life cycle;



•

continuing to improve our technological capabilities and manufacturing process expertise to further reduce delivery times, improve quality, increase yields and decrease costs; and



•

pursuing complementary acquisition opportunities to enhance our competitive position by strengthening our service offering and expanding our customer base.

(1)

EBITDA means earnings before interest expense (including amortization of debt issuance costs), income taxes, depreciation and amortization. EBITDA is presented because we believe it is an indicator of our ability to incur and service debt and is used by our lenders in determining compliance with financial covenants. However, EBITDA should not be considered as an alternative to cash flows from operating activities, as a measure of liquidity or as an alternative to net income as a measure of operating results in accordance with accounting principles generally accepted in the United States. Our definition of EBITDA may differ from definitions used by other companies.

RISK FACTORS

    Any investment in shares of our common stock involves a high degree of risk. You should consider carefully the following information about these risks, together with the other information contained in this prospectus, before you decide to buy our common stock. If any of the following risks actually occur, our business, results of operations and financial condition would likely suffer. In these circumstances, the market price of our common stock could decline, and you may lose all or part of the money you paid to buy our common stock.

Risks Related to our Company

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. The recent terrorist attacks have exacerbated the current economic slowdown. 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 $60.5 million in the fourth quarter of 2000 to $46.0 million in the first quarter of 2001, $30.7 million in the second quarter of 2001 and $26.9 million in the third quarter of 2001. A continued decline in our net sales would adversely impact our profitability and could require us to record a valuation allowance against our deferred tax assets, recognize an impairment of our intangible assets or otherwise adversely impact our results of operations.

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. Solectron, together with its recently acquired subsidiaries, SMART Modular and NEL America, accounted for 17.1% of our net sales in 2000 and 12.0% of our net sales for the first three quarters of 2001. Sales to Compaq, including sales to Compaq-directed electronic manufacturing services providers, accounted for 13.3% of our net sales in 2000 and 8.6% of our net sales for the first three quarters of 2001. Our 10 largest customers accounted for approximately 52.4% of our net sales in 2000 and 46.9% of our net sales for the first three quarters of 2001. 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.

6

    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 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

7

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 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 market segment for higher technology printed circuit boards, which may have an adverse effect on the pricing of our products.

    We may be at a competitive disadvantage with respect to price for volume production 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 for volume production. 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 in the market for higher technology printed circuit boards, 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 historically experienced lower sales in our second and third quarters due to patterns in the capital budgeting and purchasing cycles of our customers and our end-markets served. 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.

8

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;

•

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.

    During 2000 and the first three quarters of 2001, approximately 31% and 29%, respectively, 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 several 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 October 1, 2001, we had approximately $34.6 million of indebtedness. In addition, subject to the restrictions under our various debt agreements, we may incur additional indebtedness in an unrestricted amount 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.

9

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.

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 our acquired businesses 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 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 October 1, 2001, our consolidated balance sheet reflected $79.4 million of intangible assets, a substantial portion of our total assets at such date. Intangible assets consist of goodwill and other

10

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.

    In connection with our adoption of Statement of Financial Accounting Standards No. 142 in the first quarter of 2002, our impairment testing methodology will change, 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 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

11

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 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 Kent Alder, our chief executive officer. Although we have entered into employment agreements with Mr. Alder and 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 component 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 purchase orders 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

12

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, solder 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 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 October 1, 2001, Circuit Holdings held approximately 50.6% of our outstanding stock. Thayer Capital Partners controls three entities which together own approximately 60.0% of Circuit Holdings and beneficially own 59.0% 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. in managing our company. Brockway Moran & Partners Fund, L.P., owns the remaining 40% of Circuit Holdings. In addition, two of our directors are representatives 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 the approximately      % of our shares that will be beneficially owned by such entities after this offering, or approximately      % if the underwriters' option to purchase additional shares is exercised in full.

Risks Related to this Offering

We will not receive any of the proceeds from the shares sold by the selling shareholders and will have broad discretion as to the application of our net proceeds from this offering.

    We will not receive any of the proceeds from the shares sold by the selling shareholders. All of our net proceeds from this offering have been allocated to general corporate purposes. Accordingly, management will have broad discretion as to the application of the offering proceeds. Pending our use

13

of such proceeds for general corporate purposes, including working capital, capital expenditures, possible reduction of indebtedness and potential acquisitions, such proceeds will be placed in interest-bearing investments. It is possible that the return on such investments will be less than that which would be realized were we immediately to use such funds for other purposes.

Our stock price may be volatile and our stock may be thinly traded, which could cause investors to lose all or part of their investment in our stock.

    The stock market has recently experienced volatility which has often been unrelated to the operating performance of any particular company or companies. If market or industry-based fluctuations continue, our stock price could decline regardless of our actual operating performance and investors could lose a substantial part of their investment. The market price of our common stock will likely fluctuate in response to a number of factors including the following:

•

our failure to meet the earnings guidance we provide or the performance estimates of securities analysts;

•

changes in financial estimates of our revenues and operating results by securities analysts;

•

the timing of announcements by us or our competitors of significant contracts or acquisitions; and

•

general stock market conditions.

    Recently, when the market price of a company's stock has been volatile, shareholders have often instituted securities class action litigation against the company. If a class action lawsuit is filed against us, we could incur substantial costs defending the lawsuit and management time and attention would be diverted. An adverse judgment could cause our financial condition or operating results to suffer.

Substantially all of our shares are eligible for sale in the public market. This could cause the market price of our common stock to drop significantly, even if our business is doing well.

    Our current shareholders hold a substantial number of shares, which they will be able to sell in the public market in the near future. Sales of a substantial number of shares of our common stock could cause our stock price to fall. In addition, the sale of these shares could impair our ability to raise capital through the sale of additional stock.

    After this offering, we will have outstanding approximately 39.9 million shares of common stock. Approximately       million shares, including the 7.0 million shares that we and the selling shareholders are selling in this offering, may be resold immediately in the public market. The approximately       million remaining shares will be eligible for resale 90 days after the date of this offering due to agreements the selling shareholders and certain other shareholders have with us and the underwriters. However, the underwriters can waive this restriction and allow these shareholders to sell their stock at any time. Substantially all of such       million of remaining shares are also subject to the sales volume limitations of Rule 144 under the federal securities laws.

    In addition, we have filed a registration statement under Form S-8 under the Securities Act, covering the aggregate of 6,000,000 shares of common stock issued or reserved for issuance under our stock plans.

NOTE REGARDING FORWARD-LOOKING STATEMENTS

    All statements, trend analyses and other information contained in this prospectus, including those regarding markets for our products and trends in net sales, gross profit and anticipated expense levels, and any statement that contains the words "anticipate," "believe," "plan," "estimate," "expect," "intend," "seek" and other similar expressions, constitute "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. The matters described in these

14

forward-looking statements are subject to business and economic risks, including those risks identified in "Risk Factors" and in the cautionary statements elsewhere in this prospectus and our actual results of operations may differ significantly from those contained in the forward-looking statements because of such risks. Accordingly, the cautionary statements made in this prospectus apply to all forward-looking statements wherever they appear in this prospectus. In addition, these forward-looking statements reflect our current expectations, and we do not undertake to update or revise these forward-looking statements, even if experience or future changes make it clear that any projected results expressed or implied in this prospectus or other statements by us will not be realized.

    Market data and forecasts used in this prospectus including, for example, estimates of the size and growth rates of the printed circuit board market, have been obtained from independent industry sources, and we have not verified the data.

USE OF PROCEEDS

    The net proceeds to us from our sale of 2,250,000 shares of common stock in this offering will be approximately $      million, after deducting underwriting discounts and commissions and the estimated offering expenses. We will not receive any proceeds from the sale of shares by the selling shareholders.

    We intend to use such proceeds for general corporate purposes, including working capital, capital expenditures, possible reduction of indebtedness and potential acquisitions. We continually seek opportunities to acquire companies which offer services complementary to those offered by us, and potential acquisitions are an integral part of our growth strategy. However, we do not presently have any agreement or understanding with respect to any potential acquisition.

    Pending these uses, we will invest the net proceeds we receive in short-term, interest-bearing, investment-grade securities.

DIVIDEND POLICY

    We have not paid any dividends since 1998 and we do not anticipate paying any cash dividends in the foreseeable future. Additionally, our credit facility prohibits the payment of dividends. We presently intend to retain any future earnings to finance future operations and expansion of our business, and to reduce indebtedness.

EBITDA means earnings before interest expense (including amortization of debt issuance costs), income taxes, depreciation and amortization. EBITDA is presented because we believe it is an indicator of our ability to incur and service debt and is used by our lenders in determining compliance with financial covenants. However, EBITDA should not be considered as an alternative to cash flows from operating activities, as a measure of liquidity or as an alternative to net income as a measure of operating results in accordance with accounting principles generally accepted in the United States. Our definition of EBITDA may differ from definitions used by other companies.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

    You should read the following discussion in conjunction with the "Selected Financial Data" section of this prospectus, and our consolidated financial statements and the related notes included elsewhere in this prospectus, including the documents incorporated herein by reference.

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 measure customers as those companies that place at least two orders in a 12-month period. As of October 1, 2001, we had approximately 620 customers, compared to approximately 550 customers at December 31, 2000. We added approximately 145 new customers in the first three quarters of 2001. Sales to our top 10 customers represented 50.8% of our net sales in 2000 and 47.0% of our net sales in the first three quarters of 2001.

    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. Our provision for sales returns as a percentage of gross sales was less than 2% in 2000 and the first three quarters of 2001.

    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.

    Our operating expenses have historically been classified into five general categories: selling and marketing, general and administrative, amortization of intangibles, amortization of deferred retention bonus and management fees.

    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 quickturn 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.

19

    Amortization of intangibles consists of the amortization of goodwill and other intangible assets which we recorded as a result of the Power Circuits acquisition in July 1999.

    Amortization of the deferred retention bonus relates to a retention bonus plan we implemented as part of our leveraged recapitalization in December 1998. In 2000, we paid out $10.8 million to participants in order to eliminate our obligations under this plan.

    In 2000, we paid management fees for advisory services to three firms, T.C. Management, T.C. Management IV and Brockway Moran & Partners Management. These firms indirectly control our principal shareholder, Circuit Holdings, Inc. In consideration for advisory and management services rendered to us, we paid these firms an aggregate fee of $2.0 million upon consummation of our September 2000 initial public offering, which was accounted for as an offering cost. In addition, we used approximately $1.5 million of the net proceeds we received from our initial public offering to amend and consolidate these management agreements. Under the amended agreement, we no longer pay monthly management fees; however, we will pay financial advisory fees of 1.5% of the first $50 million of proceeds or value of any transaction with respect to which these entities render services and 1% of any amount of proceeds or value in excess of $50 million. Accordingly, we expect to pay a financial advisory fee of approximately $400,000 in connection with this offering, which will be accounted for as an offering cost.

    Our interest expense relates to our senior credit facility and our other long-term obligations. Primarily as a result of our repayment of indebtedness, our interest expense has decreased significantly in recent periods.

    Amortization of debt issuance costs consists of the amortization of loan origination fees and related expenses. As a result of our repayment of indebtedness and the refinancing of our senior credit facility (see "Liquidity and Capital Resources") in September 2000, we wrote off a significant portion of our debt issuance costs as an extraordinary item, and amortization of debt issuance costs has decreased.

    Interest and other income consists of interest received on cash balances as well as lease revenue received for subleasing some of our space in Santa Ana, California, to an unaffiliated tenant through March 2001. Prior to 1999, we received significant interest income due to a large cash position invested in Treasury securities.

    Prior to our leveraged recapitalization in December 1998, we were taxed for federal income tax purposes as an S corporation. Accordingly, we had no income tax expense prior to December 14, 1998. At the time of our recapitalization, we became a C corporation and the tax effect of all differences between the tax reporting and financial reporting bases of our net assets was recorded as a net deferred tax asset. The most significant basis difference resulted from an Internal Revenue Code Section 338(h)(10) tax election we made at the time of recapitalization. This election had the effect of characterizing the recapitalization and stock purchase as an asset purchase for income tax purposes. Therefore, the consideration paid to our former owners, either by us or by Circuit Holdings, in excess of the tax basis of our net assets was recorded as tax deductible goodwill of $77.5 million, even though no goodwill was recorded for financial reporting purposes. To the extent that we have future taxable income, we will realize the benefit of this tax goodwill over 15 years. This results in an annual deduction of $5.2 million which, assuming an effective income tax rate of 36%, could reduce our cash taxes payable each year by $1.9 million.

    From time to time we estimate whether we will be able to earn enough taxable income over the life of the deferred tax asset to fully realize the benefit of the asset. At the time of our recapitalization, we concluded that we were unlikely to fully realize its benefit and, accordingly, we recorded a valuation allowance against the asset. At December 31, 1999, we reassessed the realizability of our deferred tax assets and concluded, based upon our tax net operating loss of $4.9 million, among other factors, that

20

the valuation allowance was still necessary. At December 31, 1999, we had gross deferred tax assets of approximately $28.3 million and a valuation allowance of $14.8 million.

    Upon the completion of our initial public offering, we reevaluated the realizability of our deferred tax asset. We eliminated the $14.8 million valuation allowance and recorded this as an income tax benefit. Our decision was based upon the anticipated significant reduction in interest expense and increases in operating income for the quarters after our initial public offering. Should our expectations of taxable income change in future years, it may become necessary to record a valuation allowance which would adversely effect our results of operations.

Results of Operations

    The following table sets forth income statement data expressed as a percentage of net sales for the periods indicated:

First Three Quarters of 2001 Compared to First Three Quarters of 2000

Net Sales.

    Net sales decreased $39.6 million, or 27.7%, from $143.2 million for the first three fiscal quarters 2000 to $103.6 million for the first three fiscal quarters 2001. This decrease resulted from a decline in the volume of printed circuit boards sold. Net sales declined due to a significant downturn in the electronics industry and the end markets served by the company.

21

Cost of Goods Sold.

    Cost of goods sold decreased $22.8 million, or 24.1%, from $94.4 million for the first three fiscal quarters 2000 to $71.6 million for the first three fiscal quarters 2001. Lower cost of goods sold resulted from a decline in the number of printed circuit board units sold, a work force reduction and decreased employee overtime, partially offset by higher depreciation expense. As a percentage of net sales, cost of goods sold increased from 65.9% for the first three fiscal quarters 2000 to 69.2% for the first three fiscal quarters 2001. Due to a reduced revenue base, we experienced an increase in unabsorbed manufacturing overhead, resulting in a higher cost of goods sold percentage.

Gross Profit.

    Gross profit decreased $16.9 million, or 34.6%, from $48.8 million during the first three fiscal quarters 2000 to $31.9 million during the first three fiscal quarters 2001. The decrease in gross profit resulted from a lower volume of printed circuit boards produced. Our gross margin decreased from 34.1% during the first three fiscal quarters 2000 to 30.8% for the first three fiscal quarters 2001. Gross margin decreased due to lower absorption of fixed manufacturing expenses.

Operating Expenses.

    Selling and marketing expenses decreased $1.0 million from $6.9 million for the first three fiscal quarters 2000 to $5.9 million for the first three fiscal quarters 2001. The decrease resulted from lower commissions due to lower net sales levels in the first three fiscal quarters 2001.

    General and administrative expenses decreased $1.3 million from $5.4 million for the first three fiscal quarters 2000 to $4.1 million for the first three fiscal quarters 2001. This decrease was due primarily to a decline in bad debt and incentive compensation expense, partially offset by increased costs associated with being a public company. The lower bad debt provision was due to a smaller accounts receivable balance and an improved aging of accounts receivable in the first three fiscal quarters 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 totaled $3.6 million for both the first three fiscal quarters 2000 and the first three fiscal quarters 2001.

    With the net proceeds of our initial public offering in September 2000, we bought out our deferred retention bonus plan. Therefore, we recorded no amortization of the deferred retention bonus in the first three fiscal quarters 2001 as compared to $5.5 million for the first three fiscal quarters 2000.

    In conjunction with our initial public offering in September 2000, we amended and consolidated our management agreements with T.C. Management, T.C. Management IV and Brockway Moran & Partners Management. Under the amended agreement, we are not required to pay management and consulting fees, although we are required to pay financial advisory fees in the event of certain transactions as defined in the amended agreement. We had no management fees and related expenses in the first three fiscal quarters 2001, compared to $2.2 million in the first three fiscal quarters 2000.

Interest Expense.

    Interest expense decreased $9.1 million from $11.2 million for the first three fiscal quarters 2000 to $2.1 million for the first three fiscal quarters 2001. This decrease resulted from our repayment of indebtedness with the proceeds of our initial public offering in September 2000. This repayment significantly reduced our debt and decreased our accompanying level of interest expense.

22

Amortization of Debt Issuance Costs.

    Amortization of debt issuance costs decreased $701,000 from $731,000 for the first three fiscal quarters 2000 to $30,000 for the first three fiscal quarters 2001. As a result of our repayment of indebtedness and the refinancing of our senior credit facility in September 2000, we wrote off a significant portion of our debt issuance costs.

Interest Income and Other, Net.

    Interest income and other, net, which includes rental income, increased $405,000 from $124,000 for the first three fiscal quarters 2000 to $529,000 for the first three fiscal quarters 2001. This increase was due to increased interest income earned on our higher average cash balance during the first three fiscal quarters 2001. Net rental income decreased from $59,000 for the first three fiscal quarters 2000 to a net expense of $106,000 for the first three fiscal quarters 2001. During the first three fiscal quarters 2001, we received $44,000 in rental income and paid $150,000 to terminate the lease to allow for the expansion of our Santa Ana, California, facility.

Income Taxes.

    The provision for income taxes increased from a benefit of $8.7 million for the first three fiscal quarters 2000 to an expense of $6.1 million for the first three fiscal quarters 2001. The net benefit of $8.7 million for the first three fiscal quarters 2000 was due to higher pretax income offset by a one-time $14.8 million benefit recorded from eliminating our deferred tax asset valuation allowance. Our effective tax rate for the first three fiscal quarters 2001 was 36%, compared to an effective tax rate of 37% (excluding the impact of the one-time tax benefit) for the same periods in fiscal 2000. We expect to have an effective tax rate of approximately 36% for fiscal 2001.

Extraordinary Item.

    In the third fiscal quarter 2000, we recorded a loss of $6.8 million, net of a tax benefit of $3.1 million, to extinguish subordinated debt obligations carried at a discount and to write off debt issuance costs related to repayments and refinancing of our senior credit facility. We recorded no extraordinary items for the first three fiscal quarters 2001.

Year Ended December 31, 2000 Compared to the Year Ended December 31, 1999

Net Sales.

    Net sales increased $97.3 million, or 91.4%, from $106.4 million in 1999 to $203.7 million in 2000. Of this increase, approximately $31.0 million resulted from our acquisition of Power Circuits, as a full year of net sales were included in 2000. Approximately $66.3 million of the net sales increase resulted from internal sales growth. Internal sales growth increased primarily due to higher levels of units shipped and higher price levels in response to increasing demand from new and existing customers. In addition, a favorable sales mix, including a higher proportion of quick-turn and advanced technology printed circuit boards, which have higher average selling prices, contributed to higher net sales in 2000. Sales in our networking and high-end computing end markets increased in 2000 compared with 1999 as a result of strong demand in those segments.

Cost of Goods Sold.

    Costs of goods sold increased $44.9 million, or 54.6%, from $82.2 million in 1999 to $127.1 million in 2000. Higher costs of goods sold resulted from our acquisition of Power Circuits, which contributed $16.0 million to the increase. The remaining $28.9 million increase in costs was due to our increase in

23

net sales as well as higher per unit costs associated with producing quick-turn products and higher layer-count printed circuit boards.

Gross Profit.

    Gross profit increased $52.4 million, or 216.5%, from $24.2 million in 1999 to $76.6 million in 2000. Of this increase, $14.9 million resulted from the acquisition of Power Circuits. The remaining increase of $37.5 million resulted from an improved mix of higher margin quick-turn and advanced technology printed circuit boards, higher capacity utilization and generally higher unit volumes and pricing levels for all of our products. Gross margin increased from 22.8% in 1999 to 37.6% in 2000 primarily due to an improved mix of higher margin products.

Operating Expenses.

    Selling and marketing expenses increased $6.3 million, or 161.5%, from $3.9 million in 1999 to $10.2 million in 2000. Of this increase, $2.3 million resulted from the acquisition of Power Circuits. The remaining increase of $4.0 million resulted from an increase in commissions related to higher sales volume. Selling and marketing expenses increased as a percentage of net sales from 3.7% in 1999 to 5.0% in 2000 primarily due to quick-turn sales, for which we pay a higher commission rate.

    General and administrative expenses increased $5.7 million, or 219.2%, from $2.6 million in 1999 to $8.3 million in 2000. Of this increase, $1.6 million resulted from the acquisition of Power Circuits. The remaining increase of $4.1 million resulted from an increase in bad debt and incentive bonus expenses, the hiring of additional financial management and back-office staff to support our growth, and increased costs associated with being a public company.

    Amortization of intangibles increased $2.6 million, or 118.2%, from $2.2 million in 1999 to $4.8 million in 2000, due to the acquisition of Power Circuits in July 1999. We recorded a full year of amortization of intangibles in 2000 versus approximately 5¹/2 months in 1999.

    Amortization of deferred retention bonus increased $3.7 million from $1.8 million in 1999 to $5.5 million in 2000, due to the vesting and buy-out of our deferred retention bonus plan.

    Management fees and related expenses increased $1.8 million from $439,000 in 1999 to $2.2 million in 2000. Of this increase, $1.5 million resulted from a one-time payment to amend and consolidate our management agreements with T.C. Management, T.C. Management IV and Brockway Moran & Partners Management. The remaining increase resulted from additional management fees related to greater scope and services in 2000 due to the acquisition of Power Circuits as well as reimbursable expenses under the agreements.

Interest Expense.

    Interest expense increased $1.8 million, or 17.3%, from $10.4 million in 1999 to $12.2 million in 2000. This increase resulted from a higher level of indebtedness and higher interest rates through the first three quarters of 2000 associated with the acquisition of Power Circuits. Interest expense decreased significantly in the last quarter of 2000 due to lower interest rates and reduced debt levels resulting from the pay down of debt with the net proceeds of our initial public offering.

Amortization of Debt Issuance Costs.

    Amortization of debt issuance costs decreased $13,000, or 1.7%, from $755,000 in 1999 to $742,000 in 2000. Amortization of debt issuance costs increased through the first three quarters of 2000 as a result of higher levels of indebtedness associated with the acquisition of Power Circuits. These costs decreased in the fourth quarter of 2000 due to the restructuring of our credit facilities after our initial public offering. As a result of our repayment of indebtedness and the refinancing of our senior credit

24

facility (see "Liquidity and Capital Resources") in September 2000, we wrote off a significant portion of our debt issuance costs as an extraordinary item, and we expect lower future amortization.

Interest Income and Other, Net.

    Interest income and other, net, increased $127,000, or 235.2%, from $54,000 in 1999 to $181,000 in 2000, due to interest earned on our cash balances as well as additional income from a sublease that we obtained as a result of the acquisition of Power Circuits. We terminated a portion of the sublease in the second quarter of 2000 to accommodate our then-planned Santa Ana facility expansion.

Income Taxes.

    Our provision for income taxes decreased from an expense of $836,000 in 1999 to a benefit of $1.9 million in 2000. This decrease resulted primarily from a $14.8 million benefit recorded in 2000 from eliminating our deferred tax asset valuation allowance, which was only partially offset by higher taxes associated with increased pretax net income levels.

Extraordinary Items.

    We recorded extraordinary items in both 1999 and 2000. Both extraordinary items were for losses on early extinguishment of debts, net of the tax benefit. In 2000, we recorded a loss of $6.8 million, net of a tax benefit of $3.1 million, to extinguish subordinated debt obligations and eliminate our retention bonus obligation, both of which were carried at a discount, and to write off debt issuance costs related to repayments and refinancing of our senior credit facility. In 1999, we recorded a loss of $1.5 million, net of a tax benefit of $834,000, to write off debt issuance costs as a result of new financing obtained in connection with the acquisition of Power Circuits.

Liquidity and Capital Resources

    Our principal sources of liquidity have been cash provided by operations, net proceeds from our September 2000 initial public offering 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 $33.0 million for the first three fiscal quarters 2001, compared to net cash provided by operating activities of $22.6 million for the first three fiscal quarters 2000. The difference between our net income in the first three fiscal quarters 2001 of $10.7 million and our $33.0 million operating cash flow was primarily attributable to a $20.6 million decrease in accounts receivable, $9.8 million of depreciation and amortization expense, a $2.8 million decrease in inventories and a $1.8 million decrease in the deferred income tax asset, partially offset by a $3.5 million decrease in accounts payable, a $3.6 million increase in income taxes receivable, a $3.3 million decrease in income taxes payable and a $2.5 million decrease in accrued expenses and other.

    Net cash used in investing activities was $10.1 million for the first three fiscal quarters 2001, compared to net cash used in investing activities of $11.0 million for the first three fiscal quarters 2000. The decrease was due to a lower level of purchases of property and equipment. This was offset by a slight increase in deposits for equipment purchases.

    Net cash used in financing activities was approximately constant at $8.1 million for both the first three fiscal quarters 2000 and the first three fiscal quarters 2001. For the first three fiscal quarters 2000, we repaid $136.1 million of long-term debt and bought out our deferred retention bonus program at $10.8 million. We used $79.5 million in net proceeds from our initial public offering, refinanced our term debt at $45.0 million, drew $14.0 million on our revolving credit facility and used available cash to satisfy these obligations. In contrast, no cash was generated from such financing activities as the sale of

25

common stock or issuance of long-term debt during the first three fiscal quarters 2001. The significant reduction of our long-term debt in September 2000 has significantly reduced our principal payments in 2001.

    Effective September 29, 2000, we entered into an amended and restated agreement and refinanced all remaining amounts outstanding under our existing senior credit facility. Under the new agreement, we borrowed $45.0 million under a term loan. The term loan bears interest ranging from LIBOR plus 1% to LIBOR plus 2% or the Alternate Base Rate (as defined in the agreement) plus 0% to the Alternate Base Rate plus 0.5% and is due in quarterly payments of various amounts through September 30, 2005. The agreement also provides for a revolving loan commitment of up to $25.0 million, which bears interest at LIBOR plus 1% to LIBOR plus 2% or the Alternate Base Rate plus 0% to the Alternate Base Rate plus 0.5% and expires on September 29, 2005. As of October 1, 2001, we had outstanding term loan borrowings of $34.6 million and no borrowings on our revolving loan facility. As of October 1, 2001, the term loan and the revolving loan had an interest rate of 3.6% per annum. 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. As of the date hereof, we are in compliance with the covenants.

    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.

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 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 1998, the Financial Accounting Standards Board, or FASB, issued Statement of Financial Accounting Standards No. 133 "Accounting for Derivative Instruments and Hedging Activities." Statement No. 133 requires the recognition of all derivatives as either assets or liabilities in the balance sheet and the measurement date of those instruments at fair value. Gains and losses resulting from changes in the values of those derivatives would be accounted for depending on the use of the derivative and whether it qualifies for hedge accounting. Statement No. 133, as amended, is effective for fiscal years beginning after June 15, 2000. Based upon the nature of the financial instruments and our hedging activities, this pronouncement requires us to reflect the fair value of our derivative instruments (interest rate swaps) on our consolidated balance sheet. Changes in fair value of these derivatives are reflected as a component of comprehensive income. We adopted Statement No. 133

26

effective January 1, 2001. This pronouncement did not have a material impact on our financial statements.

    In June 2001, the FASB issued Statement No. 141, "Business Combinations," and Statement No. 142, "Goodwill and Other Intangible Assets," effective for 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 will apply the new rules beginning in the first quarter of 2002 or earlier for any acquisitions that occur prior to January 1, 2002. Also during 2002, we will perform the first of the required impairment tests of goodwill and indefinite-lived intangible assets as of January 1, 2002. We have not yet fully determined what the effect of these Statements will be on our results of operations and financial position. Goodwill amortization for the first three fiscal quarters 2001 was approximately $2.7 million.

    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 significant 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 do not believe the adoption of Statement 144 will have a significant impact on our consolidated financial statements.

BUSINESS

Overview

    TTM Technologies, Inc. provides time-critical, one-stop manufacturing services for highly complex printed circuit boards, which serve as the foundation of electronic products such as communications infrastructure equipment, industrial and medical equipment and servers. Our customers include manufacturers of these electronic products, commonly referred to as original equipment manufacturers, and the electronic manufacturing services companies which supply them. Products within the markets we serve have high levels of complexity and short life cycles as manufacturers continually develop new and increasingly sophisticated technology.

    We provide our customers with a manufacturing solution that encompasses all stages of an electronic product's life cycle. We utilize a facility specialization strategy in which we place each order in the facility best suited for the customer's particular delivery time and volume needs. These facilities use compatible technologies and manufacturing processes, allowing us to optimize our manufacturing operations and efficiently move orders among facilities. This strategy results in faster delivery times and enhanced product quality and consistency.

    Our one-stop manufacturing solution includes quick-turn and standard delivery time services:

Quick-turn services:

•

Prototype production.  We manufacture prototype printed circuit boards in quantities of up to 50 boards per order with delivery times ranging from as little as 24 hours to 10 days.



•

Ramp-to-volume production.  Our ramp-to-volume services typically include manufacturing up to several hundred printed circuit boards per order with delivery times ranging from two to 10 days.

    For the year ended December 31, 2000 and the first three quarters of 2001, orders with delivery requirements of 10 days or less represented 35% and 41% of our gross sales, respectively. Ten day or less orders represented a significantly higher percentage of gross sales for our Santa Ana facility, which focuses on prototype production and new customer development.

Standard delivery time services:

•

Mid-volume production.  Our mid-volume production services include manufacturing up to several hundred printed circuit boards per order with delivery times ranging from three to eight weeks.

    We provide our time-to-market services primarily to customers whose products are subject to continuous technological developments and numerous product improvements. Our significant original equipment manufacturer customers include Ciena, Compaq, General Electric, Motorola, Philips Ultrasound and Radisys. Our significant electronic manufacturing services customers include Celestica, Flextronics, Plexus, Sanmina-SCI, Solectron and Viasystems. As of October 1, 2001, we had approximately 620 customers, compared to approximately 550 customers at December 31, 2000.

Industry Background

    Printed circuit boards serve as the foundation of all complex electronic products. The printed circuit board manufacturing industry has benefited from the proliferation of electronic products in a variety of applications, ranging from consumer products, such as cellular telephones, to high-end commercial electronic products, such as communications and computer networking equipment. Printed circuit boards are manufactured from sheets of laminated material, or panels. Each panel is typically

28

subdivided into multiple printed circuit boards, each consisting of a pattern of electrical circuitry etched from copper to provide an electrical connection between the components mounted to it.

    The electronic products manufactured by our customers have high levels of complexity and short life cycles as original equipment manufacturers continually develop new and increasingly sophisticated products. We believe these characteristics benefit printed circuit board manufacturers that can assist original equipment manufacturers in bringing a product to market faster by providing the engineering expertise, process controls and execution capability to accelerate product development and quickly proceed to volume production. We believe that the time-critical and highly complex nature of new electronic products will further increase the demand for rapid production of complex printed circuit boards.

    We see several trends for the printed circuit board manufacturing industry. These include:

    Shorter electronic product life cycles.  Continual advances in technology are shortening the life cycles of complex electronic products and reducing the period during which products are profitable, placing greater pressure on original equipment manufacturers to bring new products to market faster. Original equipment manufacturers are placing increased emphasis on the prototype stage of printed circuit board production in order to accelerate product development. In addition, the rapid adoption of innovative electronic products is heightening the need for original equipment manufacturers to minimize the time required to advance products from prototype design to product introduction. We believe these time-to-market requirements are causing original equipment manufacturers to increasingly rely on printed circuit board manufacturers who have the capability to meet the needs of compressed product life cycles.

    Increasing complexity of electronic products.  The increasing complexity of electronic products is driving technological advancements in printed circuit boards. Original equipment manufacturers are continually designing more complex and higher performance electronic products, which require printed circuit boards that can accommodate higher speeds and component densities. We believe that original equipment manufacturers are increasingly relying upon larger printed circuit board manufacturers who possess the scale and financial resources necessary to invest in advanced manufacturing process technologies and sophisticated engineering staff, often to the exclusion of smaller printed circuit board manufacturers who do not possess such technology or resources.

    Decreased reliance on multiple printed circuit board manufacturers by original equipment manufacturers.  Original equipment manufacturers have traditionally relied on multiple printed circuit board manufacturers to provide different services as an electronic product moves through its life cycle. We believe that the transfer of a product among different printed circuit board manufacturers results in increased costs and inefficiencies due to incompatible technologies and manufacturing processes and production delays. As a result, we believe that original equipment manufacturers are reducing the number of printed circuit board manufacturers which they rely on, presenting an opportunity for those who can offer one-stop manufacturing capabilities.

    Consolidation of independent printed circuit board manufacturers.  As more complex electronic products proliferate, printed circuit board manufacturers require substantial investment in advanced production facilities, engineering and manufacturing expertise and process technology. These capital and technology requirements have contributed to consolidation in the printed circuit board manufacturing industry. In 1993, the 14 largest independent printed circuit board manufacturers accounted for approximately 33% of the U.S. market. In 2000, the 13 largest independent printed circuit board manufacturers accounted for approximately 54% of the U.S. market. Each of these 13 largest independent manufacturers had net sales greater than $100 million in 2000. In addition, several printed circuit board manufacturers have been acquired by electronic manufacturing services providers. We believe this development benefits the remaining independent printed circuit board manufacturers as

29

electronic manufacturing services providers may be less willing to make purchases of printed circuit boards from their vertically integrated competitors.

The TTM Solution

    We assist our customers in bringing sophisticated electronic products to market faster by offering them time-critical, one-stop manufacturing services for highly complex printed circuit boards. Key aspects of our solution include:

    Time-to-market focused services.  We deliver highly complex printed circuit boards to customers in as little as 24 hours, which allows them to rapidly develop sophisticated electronic products and quickly bring these products to market. We generated 35% and 41% of our gross sales from orders with delivery requirements of 10 days or less in 2000 and the first three quarters of 2001, respectively. Furthermore, our one-stop manufacturing capabilities allow us to rapidly advance electronic products from the prototype stage through ramp-to-volume and mid-volume production.

    Strong process and technology expertise.  We deliver time-critical, highly complex manufacturing services through our advanced manufacturing process and technology expertise. Key elements of our process expertise include the integration of our facilities with one another through compatible technology and processes and our early adoption and continuous evaluation of new technologies to further reduce delivery times, improve quality, increase yields and decrease costs.

    Our technology expertise is evidenced by our focus on high complexity, higher layer count printed circuit boards. In 2000, approximately 57% of our gross sales were from the manufacture of printed circuit boards with at least eight layers, an industry accepted measure of complexity, and 63% of our gross sales for the first three quarters of 2001. In addition, many of our lower layer count boards are complex as a result of the incorporation of other technologically advanced features.

    We also have advanced manufacturing processes that increase our efficiency. For example, our Burlington facility has the ability to manufacture printed circuit boards on 24 by 30 inch panels, compared to an industry standard of 18 by 24 inches. This larger panel size provides 67% more usable surface area than the industry standard which allows us to manufacture more printed circuit boards per panel resulting in increased manufacturing efficiencies.

    One-stop manufacturing solution.  We provide a one-stop manufacturing solution to our customers for each stage of an electronic product's life cycle by placing each order in the facility best suited for the customer's particular delivery time and volume needs. Our range of services enable us to capture mid-volume production from our quick-turn customers and quick-turn production of products from our mid-volume customers.

Strategy

    Our goal is to be the leading provider of time-critical, one-stop manufacturing services for highly complex printed circuit boards. Key aspects of our strategy include:

    Using our quick-turn capabilities to target customers in high-growth markets.  Our time-to-market philosophy is a strong complement to the rapid introduction and short product life cycle of advanced electronic products. We currently focus our marketing efforts on original equipment manufacturers and electronic manufacturing services providers in high-growth markets. In 2001, we significantly expanded our sales force from 48 at December 31, 2000 to 83 at September 30, 2001. Most of our sales force is comprised of commission-based, independent sales representatives.

    Aggressively managing our manufacturing capacity to maximize profitability.  In response to decreased product demand, we have adjusted our head count and manufacturing capacity to maximize profitability while continuing to meet the demands of our new and existing customers.

30

    Capitalizing on our one-stop manufacturing solution.  Our quick-turn capabilities allow us to establish relationships with original equipment manufacturers and electronic manufacturing services providers early in a product's life cycle and often give us an advantage in securing a preferred vendor status for subsequent mid-volume production opportunities. We also seek to gain quick-turn business from our existing mid-volume customers.

    Continuing to improve our technological capabilities and process management systems. We are consistently among the earliest adopters of new developments in printed circuit board manufacturing processes and technology. We continuously evaluate new processes and technology to further reduce our delivery times, improve quality, increase yields and decrease costs. We will continue to pursue our facility specialization strategy and deploy manufacturing processes and technology suited for each customer's delivery time and volume requirements. In addition, we will continue to develop and implement manufacturing processes and technology that allow our facilities to remain fully integrated.

    Pursuing complementary acquisition opportunities.  We consider strategic acquisitions of companies and technologies that may enhance our competitive position by strengthening our service offering and expanding our customer base. For example, our July 1999 acquisition of Power Circuits provided us with significant quick-turn manufacturing capabilities and diversified our customer base and end-markets.

Services

    We provide our customers with an integrated manufacturing solution that encompasses all stages of an electronic product's life cycle from prototype through ramp-to-volume and mid-volume production. We offer quick-turn and standard time delivery services, including the following:

    Prototype production.  We provide prototype services primarily at our facility in Santa Ana, California, where we serve customers that require limited quantities of printed circuit boards. A typical order size is up to 50 printed circuit boards with delivery times ranging from as little as 24 hours to 10 days. We believe the ability to meet our customers' prototype demands strengthens our long-term relationships and gives us an advantage in securing a preferred vendor status when customers begin ramp-to-volume and mid-volume production. Our Santa Ana facility is available seven days per week and 24 hours per day to be able to respond quickly to customer orders. We also provide prototype production as a secondary use of our Redmond facility.

    Ramp-to-volume production.  We provide ramp-to-volume services primarily at our facility in Redmond, Washington. Our ramp-to-volume service typically includes the manufacture of up to several hundred printed circuit boards per order with delivery times ranging from two to 10 days. We provide our customers with ramp-to-volume services to transition a product from prototype to mid-volume production or as a temporary solution for unforeseen manufacturing issues or customer demands. Our Redmond facility is available seven days per week and 24 hours per day to be able to respond quickly to customer orders. We also provide ramp-to-volume production as secondary uses of our Santa Ana and Burlington facilities.

    Mid-volume production.  We provide mid-volume production primarily at our facility in Burlington, Washington, where we manufacture printed circuit boards for use in the commercial production phase. Our mid-volume production service targets higher complexity printed circuit boards and manufactures up to several hundred printed circuit boards per order with delivery times typically ranging from three to eight weeks. Our mid-volume production services complement our prototype and ramp-to-volume production and allow us to offer customers one-stop manufacturing capabilities. We also provide mid-volume production as a secondary use of our Redmond facility.

Technology

    The market for our products is characterized by rapidly evolving technology. In recent years, the trend in the electronic products industry has been to increase the speed, complexity and performance of components while reducing their size. Although none of our technology is proprietary to us, we believe our technological capabilities allow us to address the needs of manufacturers who need to bring complicated electronic products to market faster. Our printed circuit boards serve as the foundation of electronic products such as communications infrastructure equipment, industrial and medical equipment and servers.

    To manufacture printed circuit boards, we generally receive circuit designs directly from our customers in the form of computer data files, which we review to ensure data accuracy and product manufacturability. Processing these computer files with computer aided design technology, we generate images of the circuit patterns that we then physically develop on individual layers using advanced photographic processes. Through a variety of plating and etching processes, we selectively add and remove conductive materials to form horizontal layers of thin circuits called traces, which are separated by insulating material. A finished multilayer circuit board laminates together a number of layers of circuitry, using intense heat and pressure under vacuum. Vertical connections between layers are achieved by plating through small holes called vias. Vias are made by highly specialized drilling equipment capable of achieving extremely fine tolerances with high accuracy. We specialize in high layer printed circuit boards with extremely fine geometries and tolerances. Because of the tolerances involved, we use clean rooms in certain manufacturing processes where tiny particles might otherwise create defects on the circuit patterns, and use automated optical inspection systems to ensure consistent quality.

    We believe the highly specialized equipment we use is among the most advanced in our industry. We provide a number of advanced technologies, including:

•

24+ layer printed circuit boards. Manufacturing printed circuit boards with higher numbers of layers is more difficult to accomplish due to the greater number of processes required. We reliably manufacture printed circuit boards with more than 24 layers in a time critical manner.



•

Blind and buried vias. Vias are drilled holes which provide electrical connectivity between layers of circuitry in a printed circuit board. They typically extend all the way through the circuit board, providing connections to external features. As the demand for wiring density in a circuit board increases, vias may block channels that are needed for circuitry. As an alternative to the difficult task of adding more layers, blind and buried via technology is employed. Blind vias connect the surface layer of the printed circuit board to the nearest inner layer. Buried vias are holes that do not reach either surface of the printed circuit board but allow inner layers to be interconnected. Since blind and buried vias only extend through the layers of the printed circuit board in which they are required, more space is available on unpierced layers. Products with blind and buried vias can be made thinner, smaller, lighter and with more functionality than products with traditional vias.



•

Fine line traces and spaces. Traces are the connecting copper lines between the different components of the printed circuit board and spaces are the distances between traces. The smaller the traces and tighter the spaces, the higher the density on the printed circuit board and the greater the expertise required to achieve a desired final yield on an order. We are able to provide .003 inch traces and spaces.



•

High aspect ratios. The aspect ratio is the ratio between the thickness of the printed circuit board to the diameter of a drilled hole. The higher the ratio, the greater the difficulty to reliably form, electroplate and finish all the holes on a printed circuit board. We are able to provide aspect ratios of up to 15:1.



•

24 by 30 inch panels. Our Burlington facility is configured for mid-volume production of printed circuit boards based on a 24 by 30 inch panel size, compared to an industry standard panel size

32

of 18 by 24 inches. This larger panel size provides 67% more usable surface area than the industry standard which allows us to manufacture more printed circuit boards per panel resulting in increased manufacturing efficiencies.

•

Thin core processing. A core is the basic inner-layer building block material from which printed circuit boards are constructed. A core consists of a flat sheet of material comprised of glass-reinforced resin with copper foil on either side. The thickness of inner-layer cores is determined by the overall thickness of the printed circuit board and the number of layers required. The demand for thinner cores derives from requirements of thinner printed circuit boards, higher layer counts and various electrical parameters. Core thickness in our printed circuit boards range from as little as 0.002 inches up to 0.062 inches. By comparison, the average human hair is 0.004 inches in diameter.



•

Sequential lamination. When using blind and/or buried via technology in a multilayer printed circuit board, we often incorporate sequential lamination manufacturing processes. Sequential lamination uses a multiple construction approach that generally increases the complexity of manufacturing due to an increase in the number of production steps. We use sequential lamination when there is a requirement for multiple sets of laminated, drilled and plated via assemblies.



•

Microvias. Microvias are small vias with diameters generally between 0.001 inches and 0.005 inches after plating. These very small vias consume much less space on the layers they interconnect, thereby providing for greater wiring densities and closer spacing of components and their attachment pads. The fabrication of printed circuit boards with microvias requires specialized equipment, such as laser drills, and highly developed process knowledge. Applications such as handheld wireless devices employ microvias to obtain a higher degree of functionality from a given surface area.



•

Micro ball grid array/Chip-on-board features. A ball grid array is a method of mounting an integrated circuit or other component to a printed circuit board. Rather than using pins, also called leads, the component is attached with small balls of solder at each contact. This array method allows for greater input/output density and requires printed circuit boards with higher layer counts and tighter lines and spaces. A micro ball grid array is an array structure where the distance between component pads is 0.031 inches or less. A chip-on-board device is a component mounted with pins where the distance between component pads is 0.016 inches or less.



•

Up to 25,000 test points per printed circuit board. Each component lead or attachment point of a printed circuit board corresponds to an electrical test point. Given the high costs of assembling printed circuit boards with multiple components, it is essential that a complete electrical test against the design intent be performed at the bare board level to ensure that all the components are working correctly. The standard metrics for assessing test capability are test equipment size and test point density, which in combination determine the testability of a product. We have the ability to manufacture printed circuit boards with over 25,000 test points per board.



•

Differential impedance. Some highly complex printed circuit boards require that the electric signals transmitted through traces be highly controlled within specific areas of the board. Our differential impedance technology regulates signals between traces and provides the means to accurately produce printed circuit boards to these requirements.

Customers and Markets

    Our customers include both original equipment manufacturers and electronic manufacturing services providers that primarily serve the networking/communications, industrial/medical and high-end computing segments of the electronics industry. We measure customers as those companies that place at least two orders in a 12-month period. As of December 31, 2000, we had approximately 550 customers, and at October 1, 2001 we had approximately 620 customers.

    Our significant customers include:

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

(1)

Sales to electronic manufacturing services providers are classified by the end markets of their customers.

(2)

Assumes that we acquired Power Circuits on January 1, 1999.

    Sales to our two largest customers, Solectron and Compaq, including Compaq-directed electronic manufacturing services providers, accounted for 17.1% and 13.3% of our 2000 net sales and 12.0% and 8.6% of our net sales in the first three quarters of 2001. Sales to our 10 top customers accounted for 52.4% of our net sales in 2000 and 46.9% of our net sales in the first three quarters of 2001.

    In 2000, 94.1% of our net sales were in the United States, 2.0% in Singapore, 1.4% in England, 1.3% in China and the remainder primarily in other European and Asian countries.

Sales and Marketing

    Our marketing strategy focuses on establishing long-term relationships with our customers' engineering staff and new product introduction personnel early in the product development phase. As the product moves from the prototype stage through ramp-to-volume and volume production, we shift our focus to the procurement department within the customer to be able to capture sales at each stage of the product's life cycle.

    Our staff of engineers, sales support and managers support our sales representatives in advising customers with respect to manufacturing feasibility, design review and technology limits through direct customer communication, e-mail and customer visits. We combine our sales efforts with customer

34

service at each facility to better serve our customers. In order to establish individual salesperson accountability for each client, each customer is assigned one salesperson for all services across all facilities.

    We market our services through a sales force consisting of direct and independent sales representatives. In 2001, we significantly expanded our sales force from 48 at December 31, 2000 to 83 at September 30, 2001. Most of our sales force is comprised of commission-based, independent sales representatives. We believe there are significant opportunities for us to increase our penetration throughout the United States through this sales force expansion.

Facilities

    Our principal manufacturing facilities are as follows:

    We own all of our facilities. While we own our facility in Burlington, we operate it under a land lease that expires in July 2025.

    We believe our facilities and state-of-the-art technology are currently adequate for our operating needs. We are qualified under various standards, including UL (Underwriters Laboratories) approval for electronics. In addition, all of our facilities are ISO 9002 certified. These certifications require that we meet standards related to management, production and quality control, among others.

    Our facilities are subject to mortgages under our senior credit facility. See "Management's Discussion and Analysis of Results of Operations and Financial Condition" and our consolidated financial statements contained elsewhere in this prospectus, including the documents incorporated herein by reference.

Suppliers

    The primary raw materials that we use in production include copper-clad layers of fiberglass of varying thickness impregnated with bonding materials, chemical solutions such as copper and gold for plating operations, photographic film, carbide drill bits and plastic for testing fixtures.

    We use just-in-time procurement practices to maintain our raw materials inventory at low levels and work closely with our suppliers to obtain technologically advanced raw materials. Although we have preferred suppliers for some raw materials, the materials we use are generally readily available in the open market and numerous other potential suppliers exist. In addition, we periodically seek alternative supply sources to ensure that we are receiving competitive pricing and service. Adequate amounts of all raw materials have been available in the past and we believe this availability will continue in the foreseeable future.

Competition

    The printed circuit board industry is highly fragmented and characterized by intense competition. Our principal domestic competitors include: DDi, Merix, the Multek subsidiary of Flextronics, Sanmina-SCI and Tyco.

    We believe we compete favorably on the following competitive factors:

•

capability and flexibility to produce customized complex products;

•

ability to offer time-to-market capabilities;

•

ability to offer one-stop manufacturing capabilities;

•

consistently high-quality product; and

•

outstanding customer service.

35

    In addition, we believe our continuous evaluation and early adoption of new or revised manufacturing and production technologies also gives us a competitive advantage. We believe that manufacturers like us who have the ability to manufacture printed circuit boards using advanced technologies such as blind and buried vias, larger panel size, sequential lamination and smaller traces and spaces have a competitive advantage over manufacturers who do not possess these technological capabilities. We believe these advanced manufacturing and production technologies are increasingly replacing and making obsolete older technologies that do not provide the same benefits. Our future success will depend in large part on whether we are able to maintain and enhance our manufacturing capabilities as new manufacturing and production technologies gain market share.

    Some of our competitors enjoy substantial competitive advantages, 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 our customers;

•

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

•

greater name recognition.

Backlog

    Although we obtain firm purchase orders from our customers, our customers typically do not make firm orders for delivery of products more than 30 to 60 days in advance. We do not believe that the backlog of expected product sales covered by firm purchase orders is a meaningful measure of future sales since orders may be rescheduled or canceled.

Governmental Regulation

    Our operations are subject to federal, state and local regulatory requirements relating to environmental compliance and site cleanups, waste management and health and safety matters. In particular, we are subject to regulations promulgated by:

•

the Occupational Safety and Health Administration pertaining to health and safety in the workplace;

•

the Environmental Protection Agency pertaining to the use, storage, discharge and disposal of hazardous chemicals used in the manufacturing processes; and

•

corresponding state agencies.

    To date, the costs of compliance and environmental remediation have not been material to us. Nevertheless, additional or modified requirements may be imposed in the future. If such additional or modified requirements are imposed on us, or if conditions requiring remediation were found to exist, we may be required to incur substantial additional expenditures.

Employees

    As of November 30, 2001, we had 864 employees, none of whom are represented by unions. Of these employees, 798 were involved in manufacturing and engineering, 37 worked in sales and marketing and 29 worked in accounting, systems and other support capacities. We have not experienced any labor problems resulting in a work stoppage and believe that we have good relations with our employees.

Legal Proceedings

    From time to time 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.
