RISK FACTORS

        Our business faces significant risks. These risks include those described below and may include additional risks and uncertainties not presently known to us or that we currently believe are immaterial. If any of the events or circumstances described in the following risks occurs, our business, operating results or financial condition could be materially adversely affected. These risks should be read in conjunction with the other information set forth in our Annual Report on Form 10-K for the fiscal year ended May 31, 2003.

Risks related to Metron.

We may not be able to meet certain covenants in or renew certain credit facilities.

        As of May 31, 2003, we had $13.1 million of short-term borrowings under our various lines of credit. Certain of our credit facilities contain financial covenants that require us to meet and maintain certain financial tests. At May 31, 2003, we were in violation of covenants under our Compass Bank facility, for which we obtained a waiver. In August 2003, Compass Bank agreed to extend the facility with a reduced availability of $4.0 million through mid-November 2003. As part of this extension, Compass Bank modified the covenants of which we were in violation, and we made a payment of $3.0 million to Compass Bank from the proceeds of our August 2003 issuance of $7.0 million principal amount of convertible debentures due 2007. Unless Compass Bank agrees to a further extension of the facility, the outstanding balance of the facility must be repaid in mid-November 2003. We intend to pursue discussions with alternative lenders to replace the Compass Bank facility prior to mid-November 2003. However, we cannot assure you that the Compass Bank facility or an alternative credit facility will be available to us after mid-November 2003 on favorable terms, or at all.

        We intend to pursue discussions with our lenders to further waive, modify or, possibly, eliminate, certain financial covenants in our credit facilities and to pursue discussions with additional lenders that may not require such financial covenants. However, we cannot give any assurance that the lenders will agree to modify or eliminate such covenants, that we can comply with the covenants of our existing credit facilities or that we will be able to enter into arrangements with additional or alternative lenders that do not require such covenants. A breach of a covenant in a credit facility could result in the lender demanding repayment of all or part of our indebtedness, could impair our ability to obtain additional access to our current or alternate credit facilities and could result in a cross-default under our convertible debentures.

        All of our lines of credit are payable on demand or subject to periodic, generally annual, review. Given recent developments in our business and industry, we cannot give any assurance that our lenders will agree to continue to make our credit facilities available to us, or that new lenders will agree to make credit facilities available to us, on terms or in amounts acceptable to us, or at all.

1



        Any failure to retain our existing credit facilities or enter into replacement facilities may impair our ability to fund our current operations and achieve our longer-term business objectives. If our significant credit facility lenders demand repayment of all or a significant portion of our indebtedness after the end of fiscal 2004, we may not have the cash resources necessary to repay such indebtedness when due.

We may need to raise additional capital, and any inability to raise required funds could harm our business.

        As of May 31, 2003, we had $12.2 million of cash and cash equivalents and $13.1 million of short-term borrowings under our various lines of credit. We incurred net losses of $26.7 million and $2.8 million for the years ended May 31, 2003 and 2002, respectively. We believe that our available cash resources, which comprise cash and cash equivalents (including the net proceeds from our August 2003 issuance of $7.0 million of convertible debentures due 2007), amounts available under our credit facilities (giving effect to the July 2003 renewal of the $3.8 million Royal Bank of Scotland facility and the August 2003 reduction in availability under the Compass Bank facility to $4.0 million) and anticipated cash from operations, will be sufficient to meet our anticipated cash requirements through fiscal 2004. However, if our revenues are lower or our expenses are higher than anticipated, or if inventory, accounts receivable or other assets require a greater use of cash than anticipated, our available cash resources, including amounts available under our credit facilities, may not be sufficient for our cash requirements. Further, existing and potential customers and vendors may take actions that could harm our liquidity position if they believe that our cash balances are not adequate. In addition, if revenues increase materially, we may need to raise additional cash resources from external sources to permit us to conduct our operations in the ordinary course of business through fiscal 2004. We also intend to seek additional financing during fiscal 2004 to meet our anticipated cash requirements for fiscal 2005 and beyond.

        We cannot give any assurance that financing will be available when needed on terms acceptable to us, or at all. If we determine that we need to issue additional equity securities or debt securities convertible into equity to address our need for cash resources, the issuance of additional equity securities or debt securities convertible into equity is likely to result in significant dilution to our existing shareholders, and the new equity securities or debt securities may have rights, preferences and privileges that are senior to those of our existing common shares. It may be necessary to raise additional funds through strategic transactions, in which event we may cease conducting or relinquish rights to a portion of our current business. Strategic transactions may not be available on terms that are favorable to us from a longer-term perspective.

        In addition to our intent to raise capital to fund our operations, we may need to raise additional capital through public or private sales of equity and/or additional borrowings for significant acquisitions, significant capital expenditures or other extraordinary transactions. If we cannot raise additional funds, if needed, on acceptable terms, we may not be able to develop our business, take advantage of future opportunities or respond to competitive pressures or unanticipated requirements, all of which could seriously harm our business and results of operations.

        Our forecast of the period of time through which our financial resources are expected to be adequate to support our operations is a forward-looking statement. This statement involves known and unknown risks, uncertainties, and other factors that may cause our, or our industry's, actual results, levels of activity, performance or achievements to be materially different from any future results, levels of activity, performance or achievements expressed or implied by the forward-looking statements. These factors are discussed in these "Risks Related to Metron" and in our Form 10-K for the fiscal year ended May 31, 2003.

We are dependent on a few key suppliers for a majority of our revenue; therefore, the loss of or change in our relationship with one or more of our key suppliers could seriously harm our business.

        If, for any reason, any of our key suppliers were to materially reduce its business or terminate its relationship with us, the loss of the key principal would have a material adverse effect on our business. In each of our last three fiscal years, a majority of our revenue came from the sale of products from five or fewer of our suppliers, which is how we refer to the semiconductor materials and equipment companies we represent. Although the suppliers that comprise our largest sources of revenue may change from period to period, we expect that revenue from the sale of products of a relatively small number of suppliers will continue to account for a substantial portion of our revenue for at least the next five years.

        All of the semiconductor materials, equipment and products we market, sell, service and support are sold pursuant to agreements with our suppliers. These agreements are generally cancelable at will, subject to notification periods that range from 30 days to two years. We generally do not sell competing products in the same market, and, therefore, the number of suppliers we can represent at any one time is limited. It is likely that in the future some of our suppliers will terminate their relationships with us upon relatively short notice. If we lose a key principal, we may not be able to find a replacement quickly, or at all. The loss of a key principal may cause us to lose customers and incur expenses associated with ending our agreement with that principal. We may lose suppliers for various reasons, including:

        We have lost suppliers in the past. For example, in March 1999, A.G. Associates was acquired by Steag. As a result of this acquisition, we ceased marketing and selling A.G. Associates' products in September 1999. In July 1999, FSI sold its chemical management division to BOC Edwards. As a result of this divestiture, we no longer market and sell these products. In October 1999, Applied Materials acquired Obsidian. As a result of the acquisition, Obsidian terminated its agreement with us. In January 2001, we entered into an agreement with Entegris, Inc. to modify our existing distribution relationship, whereby Entegris assumed direct sales responsibility for products from its Microelectronics Group in Europe beginning April 1, 2001, and in Asia beginning May 1, 2001. In May 2002, by mutual agreement, we terminated our distributor agreement with August Technology, except in Korea. In August 2002, Cabot Microelectronics advised us of its decision to assume the direct distribution of its products in Europe and Singapore; the effective date of the transition was June 1, 2003. In October 2002, FSI advised us of its decision to assume the direct distribution of its products in Europe (except Israel) and Asia; the effective date of the transition was March 1, 2003. Our world-wide revenue for FSI products for the year ended May 31, 2001 was 24.5% of revenues. Our revenues for FSI products and services in Europe and Asia were approximately $29.0 million and $26.9 million (12.5% and 11.4% of revenue) for the years ended May 31, 2002 and 2003, respectively.

The semiconductor industry is highly cyclical, and during its periodic downturns, our operating results will deteriorate.

        The semiconductor industry is highly cyclical and historically has experienced periodic downturns, which often have resulted in decreased expenditures by semiconductor manufacturers. These downturns

3



generally have adversely affected the sales, gross profits and operating results of semiconductor materials and equipment suppliers. Our business depends in large part on the procurement expenditures of semiconductor manufacturers, which, in turn, depend on the current and anticipated demand for semiconductors and products utilizing semiconductors. The downturn in the semiconductor industry from mid-1996 until the end of 1998 had a material adverse effect on our operating results. In February 2001, we started to experience a downturn in new orders, as well as delays in shipment for existing orders. The continuation of the downturn for any extended period, or an increase in the number of shipment delays, would have a materially adverse effect on our operating results.

We may not be able to successfully implement our restructuring efforts, and such efforts may adversely impact our ability to retain and attract future employees.

        In October 2002, we announced that we would be reducing our workforce by approximately 125 employees worldwide. The total number of employees terminated as of May 31, 2003 was 125 people. On March 1, 2003, we transferred 93 employees to FSI. In addition, during our fourth quarter of fiscal 2003, we abandoned unutilised leased facilities as part of our restructuring. Workforce reductions, including the one we announced in fiscal 2003, could result in a temporary lack of focus and reduced productivity by our remaining employees, which in turn may affect our revenues in the current or a future quarter. In addition, prospects and current customers may decide to delay or not purchase our products due to the perceived uncertainty caused by our reduction in force. We cannot assure you that we will not reduce or otherwise adjust our workforce again in the future or that the related transition issues associated with such a reduction will not occur again. Further, we believe that our future success will depend in large part upon our ability to attract and retain highly-skilled personnel. We may have difficulty attracting such personnel as a result of a perceived risk of future workforce reductions.

If we are unable to successfully identify new products and enter into and implement arrangements with the suppliers of these products, our business will be seriously harmed.

        To the extent we are unable to enter into relationships with suppliers who anticipate or respond adequately to technological developments or customer requirements, we could suffer a loss of competitiveness. Such loss, or any significant delays in product development or introductions by these suppliers, could have a materially adverse effect on our business. The semiconductor materials and equipment market is subject to rapid technological change, changing customer requirements and frequent new product introductions. Because of this, the life cycle of products that we market and sell is difficult to determine. Our future success will depend to a significant extent on our suppliers' ability to keep pace with changes in the market and, particularly because we generally do not carry competing product lines, on our ability to identify and obtain new product lines which achieve market success.

We face intense competition from companies with significantly greater financial, technical and marketing resources, which could adversely affect our ability to maintain or increase sales.

        We face intense competition on two distinct fronts: competition for product lines and competition for customers.

If we are unable to compete successfully for product lines against independent sales and distribution companies that have greater financial resources, are more established or have longer-standing relationships with semiconductor materials and equipment manufacturers, we will be unable to offer competitive products, which will negatively impact our sales.

        We compete with independent sales and distribution companies for the right to sell specific product lines in specific territories. We believe that our most formidable competition comes from regionally established semiconductor materials and equipment distribution companies. Some of these independent sales and distribution companies have substantially greater financial resources to devote to

4



a particular region than we do, are better established in particular regions than we are, have greater name recognition in their chosen markets than we have and have long-standing collaborative business relationships with semiconductor materials and equipment manufacturers which are difficult to overcome. If we are unable to effectively compete with sales and distribution companies to attract and retain suppliers, our business will be adversely affected.

If we are unable to compete for customers owing to our inability to provide sales, marketing and support services or particular product offerings, our ability to maintain or increase sales will be adversely affected.

        We compete for orders from semiconductor manufacturers with established semiconductor materials and equipment manufacturers who sell directly to customers and with independent sales and distribution companies and sales representatives. We believe that to compete effectively for customers we must maintain a high level of investment in marketing, customer service and support in all of the markets in which we operate, and we may not have sufficient financial resources, technical expertise or marketing, services and support capabilities to continue to compete successfully in the future. Some of our competitors have greater name recognition in the territories they serve and have long-standing relationships with semiconductor manufacturers that may give them an advantage in attracting and retaining customers. Furthermore, we believe that once a semiconductor manufacturer has selected a particular product for a specific use from a vendor that is not one of our suppliers, it may be difficult to achieve significant sales of a competing product to that customer unless there are compelling reasons for the customer to switch products, such as significant performance or cost advantages.

        We anticipate that as we continue to diversify our product portfolio and expand into new markets for our suppliers' products, we will encounter additional competition for customers. If we cannot continue to compete successfully for customers in the future, any such lack of success will have a significant negative impact on our business.

        The management information systems that we currently use in our day-to-day operations are not integrated across the globe and some of them need to be upgraded. Upgrading them will be costly, and if the new system is not successfully implemented, our business may suffer material adverse consequences.

        While our financial reporting management information system is integrated and operational, the current management information systems that we use to control our day-to-day operations are not integrated across the globe. To accommodate growth in the past, we have had to hire additional people to compensate for the lack of a fully-functional, integrated operations management information system. We are currently investing in a new operations management information system in order to maintain our current level of business and accommodate any future growth. We commenced implementation of the new system in Europe in 2001 and 2002. We plan to implement the financial management reporting system to support the centralization of our European operations into an entity called Metron Europa by our third quarter of fiscal 2004, and to commence the implementation in Asia with the next installation scheduled for Singapore after implementation in Metron Europa has been completed. We currently anticipate that the total costs associated with the implementation of the new system will be approximately $12.0 to $15.0 million and that the system will be fully implemented over the next 24 months. Any failure to successfully implement our new operations management information system may result in delayed growth, increased inefficiency due to a lack of centralized data, higher inventories, increased expenses associated with employing additional employees, a loss of our investment in the new operations management information system and may have additional material adverse effects on our business.

5



We need to successfully manage the anticipated expansion in our operations or our business may suffer material adverse consequences.

        To the extent we are unable to effectively manage future expansion and the system and procedural transitions required by expansion, our business and our operating results could be seriously harmed. We have expanded our operations in the past and anticipate future expansion of our operations through acquisitions and otherwise. Our growth has placed and will continue to place significant demands on our management, operational, financial and technical resources, as well as our accounting and control systems, as we work to integrate geographically dispersed offices and administrative personnel, diverse service and maintenance operations and different accounting and financial systems. Our future operating results will depend on the ability of our management and other employees to:

        We cannot predict whether these efforts will be successful or will occur in a timely or efficient manner. We may not be able to install adequate control systems in an efficient and timely manner, and our current or planned operational systems, procedures and controls may not be adequate to support our future operations. The difficulties associated with installing and implementing new systems, procedures and controls may place a significant burden on our management and our internal resources. Delays in the implementation of new systems or operational disruptions when we transition to new systems would impair our ability to accurately forecast sales demand, manage our product inventory and record and report financial and management information on a timely and accurate basis.

Our indebtedness and debt service obligations may adversely affect our cash flow and ability to obtain additional financing.

        Our annual debt service obligations on our 8% convertible debentures due 2007 are approximately $0.6 million per year in interest payments. Our indebtedness could have significant negative consequences, including: requiring the dedication of a portion of our expected cash flow from operations to service our indebtedness if we do not make interest payments in our common shares rather than cash, thereby reducing the amount of our expected cash flow available for other purposes, including capital expenditures; increasing our vulnerability to general adverse economic and industry conditions; limiting our ability to obtain additional financing; limiting our flexibility in planning for, or reacting to, changes in our business and the industry in which we compete; and placing us at a possible competitive disadvantage to less leveraged competitors and competitors that have better access to capital resources. The existence of debt service obligations and the anti-dilution provisions of our debentures also may limit our ability to obtain additional financing on terms favorable to us.

We may not be successful in our effort to penetrate Japan, which could limit our future growth.

        On April 8, 2003, we announced the opening of Metron Technology (Japan) K.K. ("Metron Japan") in Yokohama, Japan. Approximately 22% of the world's production of semiconductors in 2002 took place in Japan. Accordingly, to reach all of the world's major semiconductor markets, we will need to be successful in our efforts to establish or acquire sales, marketing and/or service capabilities in Japan. Historically, it has been difficult for non-Japanese companies to succeed in establishing themselves in Japan. We intend Metron Japan to serve as our headquarters for building partnerships with original equipment manufacturers (OEMs) in Japan and to provide service and outsource

6



solutions in the local market. We cannot predict whether our efforts to penetrate the Japanese market will be successful. If we are not successful in our efforts to penetrate the Japanese market, our future growth may be limited.

We expect continued downward pressure on the gross margins of the products we sell, and as a result, if we are unable to continue to decrease our operating expenses as a percentage of sales or find replacement product lines with higher gross margins, we will be unable to increase or maintain our operating margins.

        Particularly during industry down cycles, pressure on the gross margins of the products we sell is intense and can adversely impact our financial performance. We have experienced significant downward pressure on our gross margins, mainly as a result of sales discounts offered by our competitors and pressure from our customers to reduce prices and from our suppliers to reduce the discounts they provide to us. This, in turn, has put significant downward pressure on our operating margins. To maintain or increase our gross margins, we must develop and maintain relationships with suppliers who introduce new products and product enhancements on a timely basis. As a result of continued pressure on gross margins, we must find ways to decrease our selling, general, administrative and other expenses as a percentage of sales to increase or maintain our operating margins. If our suppliers cannot continue to innovate, if we cannot maintain our relationships with innovating suppliers, if we cannot otherwise identify product lines with higher gross margins or if we cannot successfully manage our selling, general, administrative and other expenses, our operating margins may decrease. If our operating margins decline as a result of these factors, our business would be harmed.

Our employment costs in the short-term are to a large extent fixed, and therefore any cyclical revenue shortfall could adversely affect our operating results.

        Our operating expense levels are based in significant part on our head count, which is generally driven by longer-term revenue goals. For a variety of reasons, particularly the high cost and disruption of lay-offs and the costs of recruiting and training, our head count in the short-term is, to a large extent, fixed. In addition, approximately half of our employees are in Europe, and the costs associated with any reductions of our labor force in Europe are high. As a result of these factors, we were unable to reduce employment costs in a timely manner to compensate for the cyclical revenue or gross margin shortfall we have suffered during the current downturn, which has had a material adverse effect on our operating results. We cannot assure you that we will be able to reduce employment costs sufficiently to compensate for future cyclical revenue shortfall.

We may bear inventory risk due to an inability to return products, and if we are unable to manage our inventory effectively, our operating results could be adversely affected.

        We bear inventory risk because we generally take title to the products we sell when we receive them from our suppliers, and we cannot always return products to the principal in the event the products are not sold. Our customers do not always purchase at the time or in the quantities we originally anticipated. For example, as a result of the current industry downturn beginning in fiscal 2001, we had excess inventory for which we booked reserves in Europe, the United States and Asia. Typically, products cannot be returned to suppliers after they have been in our inventory for a certain period of time; this time period varies depending on the product and the principal. In addition, although it is typical when a relationship with a principal terminates for that principal to repurchase most of the inventory we have of that principal's products, it is possible under certain circumstances that a principal may be unable or unwilling to repurchase our inventory. If we fail to manage our inventory and accumulate substantial product that cannot be returned, our operating results could be adversely affected. Furthermore, if a principal cannot provide refunds in cash for the inventory we desire to return, we may be forced to dispose of inventory below cost, and this may have a material adverse effect on our financial results.

7



Our revenue and operating results may fluctuate in future periods, which could adversely affect our share price.

        In the past, we have experienced fluctuations in our quarterly and annual operating results and anticipate that these fluctuations will continue in the future due to a variety of factors, many of which are outside our control. Fluctuations in our results could cause our share price to decline substantially. We believe that period-to-period comparisons of our results of operations may not be meaningful, and you should not rely upon them as indicators of our future performance. Our sales in, and the operating results for, a particular quarter can vary significantly due to a variety of factors, including those described elsewhere in our Form 10-K for the fiscal year ended May 31, 2003 and the following:

        As a result of the factors listed above, our future operating results are difficult to predict. Further, we base our current and future expense plans in significant part on our expectations of our longer-term future revenue. As a result, we expect our expense levels to be relatively fixed in the short-run. A decline in revenue for a particular quarter may disproportionately affect our net income in that quarter. If our revenue is below our projections, then our operating results will also be below expectations and,

8



as we have in the past, we may even have losses in the short-run. Any one of the factors listed above, or a combination thereof, could adversely affect our quarterly results of operations, and consequently may cause a decline in our share price.

We depend on sales to a relatively small number of customers for a significant portion of our revenue, and if any of our large customers were to stop or reduce their purchasing from us, this would materially and adversely affect our revenue.

        A loss or a significant reduction or delay in sales to any of our major customers could materially and adversely affect our revenue. We depend on a small number of customers for a substantial portion of our revenue. In fiscal 2003, our top ten customers accounted for an aggregate of 42% of our sales. Although a ranking by revenue of our largest customers will vary from period to period, we expect that revenue from a relatively small number of customers will account for a substantial portion of our revenue in any accounting period for the foreseeable future. Consolidation in the semiconductor industry may result in increased customer concentration and the potential loss of customers as a result of acquisitions. Unless we diversify and expand our customer base, our future success will significantly depend upon certain factors which are not within our control, including:

        If any of our largest customers were to stop or reduce their purchasing from us, our financial results could be adversely affected. In October 2002, FSI advised us of its decision to assume the direct distribution of its products in Europe (except Israel) and Asia; the effective date of the transition was March 1, 2003. This transition will mean that we can no longer sell these FSI products to our customers in these regions, which could result in the loss of some customers. Our world-wide revenue for FSI products for the year ended May 31, 2001 was 24.5% of revenues. Our revenues for FSI products and services in Europe and Asia were approximately $29.0 million and $26.9 million (12.5% and 11.4% of revenue) for the years ended May 31, 2002 and 2003, respectively. A significant decrease in sales to a major customer or the deferral or cancellation of any significant order would have a material adverse effect on our operating results.

Our sales cycle, particularly for equipment, is long and unpredictable, which could require us to incur high sales and marketing expenses with no assurance that a sale will result.

        Sales cycles for some of our products, particularly equipment, can run as long as 12 to 18 months. As a result, we may not recognize revenue from efforts to sell particular products for extended periods of time, or at all. We believe that the length of the sales cycle may increase as some current and potential customers of our key suppliers centralize purchasing decisions into one decision-making entity. We expect this may intensify the evaluation process and require us to make additional sales and marketing expenditures with no assurance that a sale will result.

We have recently expanded our operations to include manufacturing, an activity with which we do not have significant experience. This new activity will require us to hire managers and employees with different skills from those of our existing employees and to develop systems to manage processes with which we have no prior experience.

        We now manufacture, under license from the original equipment manufacturer, Varian sputtering (PVD) equipment, licensed from Novellus, and AG Associates rapid thermal processing (RTP) equipment, licensed from Mattson. Prior to our entry into what is commonly called the legacy equipment business, we did not manufacture any equipment. With our entry into this business, we have had to hire managers and other employees who have different skills from those of our existing

9



employees. We have also had to install new systems to keep track of manufacturing inventories. As a consequence of our lack of experience, our newly initiated manufacturing activity may incur unanticipated costs, and we may not realize the gross margins that we planned to in making the necessary investments. In May 2002, we acquired certain assets of Advanced Stainless Technologies (AST), a Texas-based manufacturer of electro-polished stainless steel tubes and fittings. We had no prior experience of operating a plant such as AST's, and we may incur unexpected costs in connection with AST's business.

We have not yet developed a strategy to sell to our customers over the Internet, and if a competitor develops and implements an effective e-commerce strategy, we may lose some of our customers, which would have a negative impact on our results of operations.

        Although we have begun efforts to develop an e-commerce strategy, we have not implemented a process to sell to our customers over the Internet. Because our suppliers grant us the right to sell their products only for specific territories and sales conducted over the Internet may occur anywhere around the globe, it is difficult to adopt e-commerce practices in our industry. If our suppliers decide to directly distribute their products over the Internet, if our competitors develop a successful strategy for engaging in e-commerce or if our customers require e-commerce capabilities which we are unable to provide, we may lose customers, which would have a negative impact on our revenue and on our operating results.

Risks related to our international operations.

Economic difficulties in countries in which we sell our products can lead to a decrease in demand for our products and impair our financial results.

        The volatility of general economic conditions and fluctuations in currency exchange and interest rates can lead to decreased demand in countries in which we sell products. For example, in 1997 and 1998 many Asian countries experienced economic and financial difficulties. During this period, we experienced cancellation or delay of orders for our products from customers in Asia, which adversely affected our results of operations. Moreover, any economic, banking or currency difficulties experienced by countries in which we have sales may lead to economic instability in those countries. This in turn may result in the cancellation or delay of orders for our products from customers in those countries, thus adversely affecting our results of operations.

Most of our product sales are outside the United States, and currency fluctuations may impair our financial results.

        While most of our international sales are denominated in United States dollars, some are denominated in various foreign currencies. To the extent that our sales and operating expenses are denominated in foreign currencies, our operating results may be adversely affected by changes in exchange rates. For example, in the second quarter of fiscal 2002, we recorded exchange losses of approximately $470,000. In fiscal 2003, approximately $449,000 of the foreign exchange loss pertained to the cost of hedging the Israel Shekel. The higher cost was primarily due to the difference in the interest rates between the United States dollar and Israel Shekel. Given the number of currencies involved, the substantial volatility of currency exchange rates, and our constantly changing currency exposures, we cannot predict the effect of exchange rate fluctuations on our future operating results. Although we engage in foreign currency hedging transactions from time to time, these hedging transactions can be costly, and, therefore, we do not attempt to cover all potential foreign currency exposures. These hedging techniques do not eliminate all of the effects of foreign currency fluctuations on anticipated revenue.

Risks related to investing in our common shares.

We are significantly controlled by FSI and Entegris, which may limit your ability to influence the outcome of director elections and other shareholder matters.

        As of May 31, 2003, FSI owned 16.8%, and Entegris owned 12.4% of our outstanding shares. By virtue of their share ownership, FSI and Entegris can exercise significant voting control over Metron. As a result, each of these shareholders has significant influence over all matters requiring shareholder approval, including the election of directors, which may have the effect of delaying or preventing a third party from acquiring control over us.

Our share price is volatile.

        The trading price of our common shares is subject to wide fluctuations in response to various factors, some of which are beyond our control, including factors discussed in our Form 10-K for the fiscal year ended May 31, 2003 and the following:

        In the past, securities class action litigation has often been brought against a company following periods of volatility in the market price of its securities. We may in the future be the target of similar litigation. Securities litigation may result in substantial costs and divert management's attention and resources, which may seriously harm our business.

Risks related to being a Dutch company.

Our Supervisory Board has the authority to issue shares without shareholder approval, which may make it more difficult for a third party to acquire us.

        As a Netherlands "Naamloze Vennootschap," or N.V., we are subject to requirements not generally applicable to corporations organized in United States jurisdictions. Among other things, under Netherlands law, the issuance of shares of an N.V. must be approved by the shareholders unless the shareholders have delegated the authority to issue shares to another corporate body. Our articles of association provide that the shareholders have the authority to resolve to issue shares, common or preferred. The shareholders may designate the Company's Supervisory Board as the corporate body with the authority to adopt any resolution to issue shares, but this designation may not exceed a period of five years. Our articles also provide that as long as the Supervisory Board has the authority to adopt a resolution to issue shares, the shareholders will not have this authority. Pursuant to the Metron articles, the Supervisory Board has the authority to adopt resolutions to issue shares until five years from the November 19, 1999, deed of conversion from a B.V. to an N.V. and the related amendment of our articles of association. This authorization of the Supervisory Board may be renewed by the shareholders from time to time. As a result, our Supervisory Board currently has the authority to issue common and preferred shares without shareholder approval unless such approval is required under the terms of our Nasdaq listing agreement.

        The issuance of preferred shares could have the effect of making it more difficult for a third party to acquire, or of discouraging a third party from acquiring, a majority of the outstanding shares of our share capital.

It may not be possible to enforce United States judgments against Netherlands corporations, directors and others.

        Our articles provide that Metron has two separate boards of directors, a Managing Board and a Supervisory Board. A significant percentage of our assets are located outside the United States. Furthermore, judgments of United States courts, including judgments against us, our directors or our officers predicated on the civil liability provisions of the federal securities laws of the United States, are not directly enforceable in The Netherlands.

Provisions of our charter documents and Dutch law could discourage potential acquisition proposals and could delay, deter or prevent a change in control.

        Our articles of association and the applicable law of The Netherlands contain provisions that may be deemed to have anti-takeover effects. These provisions may delay, defer or prevent a takeover attempt that a shareholder might consider in the best interest of our shareholders. For example, our articles may be amended only pursuant to a proposal of the Supervisory Board followed by a resolution of a general meeting of shareholders. To amend our articles requires that at a general meeting of shareholders, (1) more than half of the issued share capital is represented and (2) the resolution to amend the articles is supported by a two-thirds majority of the valid votes cast. This supermajority voting requirement may have the effect of discouraging a third party from acquiring a majority of the outstanding Metron shares. In addition, these provisions could have a negative impact on our share price. Furthermore, some United States tax laws may discourage third parties from accumulating significant blocks of our common shares.

SELLING SECURITYHOLDERS

Summary

        Set forth below is a summary of the transaction pursuant to which we issued the warrants and debentures to the Selling Securityholders, as well as the principal terms of the warrants and debentures and our relationship with the Selling Securityholders.

        On August 25, 2003, we completed the sale of $7.0 million aggregate principal amount of 8% Convertible Debentures (the "Debentures") and warrants to purchase up to 811,594 of our common shares (the "Warrants"), to the Selling Securityholders pursuant to Section 4(2) of the Securities Act and Rule 506 promulgated thereunder (the "Financing"). We received gross proceeds of approximately $7.0 million from the Financing, $3.0 million of which was used to repay short-term indebtedness, with the remainder expected to be used for working capital. The following investors purchased the Debentures and the Warrants: Midsummer Investment, Ltd., Omicron Master Trust, Islandia, L.P., Enable Growth Partners, L.P, J. M. Hull Associates, L.P. and S.F. Capital Partners Ltd.

        The Debentures and the Warrants were issued pursuant to the Subscription Agreement dated as of August 25, 2003 between us and the investors that purchased the Debentures and the Warrants. The Debentures mature on February 25, 2007, bear interest at the rate of 8% per annum and are convertible into 1,846,964 of our common shares at a per share conversion price of $3.79. The conversion price of the Debentures is subject to limited anti-dilution adjustments under certain circumstances. We are entitled to issue common shares in lieu of the cash payment of interest on the Debentures, subject to certain limitations. We also are entitled to force conversion of the Debentures into common shares in the event our common share price exceeds $10.34 per share for 20 consecutive trading days, provided certain conditions are met. Generally, these conditions are that:

14


        Each of the Warrants is immediately exercisable and is exercisable on or prior to the earlier of (i) the close of business on August 25, 2007 or (ii) 30 days after we give notice of mandatory termination, but not thereafter. We may give notice of mandatory termination of a warrant provided that (i) the common shares issuable upon conversion of the warrant are registered for resale pursuant to the Securities Act of 1933 or are freely tradable without restriction or legend and have been continuously for at least the 20-trading day period immediately preceding the date of the notice of termination, (ii) the common shares are listed or quoted for trading on the Nasdaq National Market continuously during the 20-trading day period immediately preceding the date of the notice of mandatory termination and (iii) the price of our common shares is equal to or greater than $10.34 for each of the 20 trading days immediately preceding the date of notice of termination (subject to adjustment for reverse and forward stock splits, stock dividends, stock combinations and other similar transactions). Warrants to purchase up to 405,797 common shares are exercisable at a price per share of $3.97, subject to adjustment, and Warrants to purchase up to 405,797 common shares are exercisable at a price per share of $4.31, subject to adjustment.

        We entered into the Registration Rights Agreement (the "Rights Agreement"), dated as of August 25, 2003, with the Selling Securityholders. Pursuant to the Rights Agreement, we agreed to file with the SEC on or before September 24, 2003 a registration statement covering the resale of 150% of the common shares issuable in connection with the Financing. Accordingly, we filed a Registration Statement on Form S-3, of which this prospectus forms a part, on September 19, 2003, with respect to the resale of these shares from time to time.

        Other than as set forth above, we have had no material relationship with any of the Selling Securityholders during the past three years.

Selling Securityholders

        We have filed a registration statement with the SEC, of which this prospectus forms a part, with respect to the resale of our common shares covered by this prospectus from time to time. Our common shares being offered by this prospectus are being registered to permit secondary public trading of our common shares. Subject to the restrictions described in this prospectus, the Selling Securityholders may offer our common shares covered under this prospectus for resale from time to time. The common shares covered, as to their resale, under this prospectus include shares issuable upon conversion of the Debentures and exercise of the Warrants, including any additional shares issuable to prevent dilution as a result of stock splits, stock dividends or similar events, and shares issuable in lieu of the cash payment of interest on the Debentures. In addition, subject to the restrictions described in this prospectus, the Selling Securityholders may sell, transfer or otherwise dispose of a portion of our common shares being offered under this prospectus in transactions exempt from the registration requirements of the Securities Act. See "Plan of Distribution."

        The table below presents information as of September 8, 2003 regarding the Selling Securityholders and the shares that the Selling Securityholders (and their pledgees, assignees and successors-in-interest) may offer and sell from time to time under this prospectus. The table is prepared based on information supplied to us by the Selling Securityholders. Although we have assumed for purposes of the table below that the Selling Securityholders will sell all of the shares offered by this prospectus, because the Selling Securityholders may offer from time to time all or some of their shares covered under this prospectus, or in another permitted manner, no assurances can be given as to the actual number of shares that will be resold by the Selling Securityholders or that will be held by the Selling Securityholders after completion of the resales. In addition, the Selling Securityholders may have sold, transferred or otherwise disposed of the Debentures or the Warrants in transactions exempt from the registration requirements of the Securities Act since the date the Selling Securityholders

15



provided the information regarding their securities holdings. Information concerning the Selling Securityholders may change from time to time and changed information will be presented in a supplement to this prospectus if and when necessary and required. There are currently no agreements, arrangements or understandings with respect to the resale of any of the shares covered by this prospectus.

        The table below lists the Selling Securityholders and other information regarding the ownership of the common shares by each of the Selling Securityholders. The column titled "Number of Shares Being Offered" lists for each Selling Securityholder, the number of common shares, based on its ownership of the Debentures and/or Warrants that may be issuable to the Selling Securityholder upon conversion of the Debentures, payment of the interest on the Debentures in common shares (notwithstanding the fact that the we can elect to pay interest on the Debentures in cash) and exercise of the Warrants, without regard to any limitation on conversions, exercise or payments. Because payments of interest on the Debentures in common shares is based on a formula that takes into account the market price of our common shares, the numbers listed in the table below may fluctuate from time to time. We determined the number of common shares to be offered for resale by the Selling Securityholders under this prospectus by agreement with the Selling Securityholders under the terms of the Rights Agreement. In determining the number of shares to be offered, we assumed the following:

        The amounts and percentages under the headings "Deemed Ownership Prior to the Offering" and "Number of Shares Being Offered" reflect the shares issuable under conversion of the Debentures and exercise of the Warrants assuming the events in steps 1. through 5. above.

        Under the terms of the Debentures and the Warrants (collectively, the "Securities"), no Selling Securityholder may receive shares in connection with the conversion of the Debentures or the exercise of the Warrants, to the extent such conversion or exercise would cause such Selling Securityholder, together with its affiliates, to beneficially own more than 4.99% (9.99% in the case of a forced conversion of the Debentures or mandatory termination of the Warrants) of our then outstanding common shares following such conversion or exercise, excluding for purposes of such determination common shares issuable upon conversion of the Debentures which have not been converted and upon exercise of the Warrants that have not been exercised. In addition, under the terms of the Securities, Metron may not issue pursuant to the Securities more than 19.999% of the number of common shares outstanding immediately prior to the Financing unless shareholder approval has been obtained for such issuance. The numbers in the table below do not reflect these limitations.

16



        The applicable percentages of ownership are based on an aggregate of 12,609,078 shares of our common shares issued and outstanding on August 31, 2003.

Omicron Capital, L.P., a Delaware limited partnership ("Omicron Capital"), serves as investment manager to Omicron Master Trust, a trust formed under the laws of Bermuda ("Omicron"), Omicron Capital, Inc., a Delaware corporation ("OCI"), serves as general partner of Omicron Capital, and Winchester Global Trust Company Limited ("Winchester") serves as the trustee of Omicron. By reason of such relationships, Omicron Capital and OCI may be deemed to share dispositive power over the common shares owned by Omicron, and Winchester may be deemed to share voting and dispositive power over the common shares owned by Omicron. Omicron Capital, OCI and Winchester disclaim beneficial ownership of such common shares. Omicron Capital has delegated authority from the board of directors of Winchester regarding the portfolio management decisions with respect to the common shares owned by Omicron and, as of April 21, 2003, Mr. Olivier H. Morali and Mr. Bruce T. Bernstein, officers of OCI, have delegated authority from the board of directors of OCI regarding the portfolio management decisions of Omicron Capital with respect to the common shares owned by Omicron. By reason of such delegated authority, Messrs. Morali and Bernstein may be deemed to share dispositive power over the common shares owned by Omicron.

No other person has sole or shared voting or dispositive power with respect to the common shares being offered by Omicron, as those terms are used for purposes under Regulation 13D-G of the Securities Exchange Act of 1934, as amended. Omicron and Winchester are not "affiliates" of one another, as that term is used for purposes of the Securities Exchange Act of 1934, as amended, or of any other person named in this prospectus as a selling stockholder. No person or "group" (as that term is used in Section 13(d) of the Securities Exchange Act of 1934, as amended, or the SEC's Regulation 13D-G) controls Omicron and Winchester.

PLAN OF DISTRIBUTION

        The Selling Securityholders or any of their permitted pledgees, donees, assignees and successors-in-interest may, from time to time, sell any or all of their common shares on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These sales may be at fixed or negotiated prices. The Selling Securityholders may use any one or more of the following methods when selling shares:

        The Selling Securityholders may also sell shares that qualify for sale pursuant to Rule 144 under the Securities Act, rather than under this prospectus. In effecting sales, broker-dealers engaged by the Selling Securityholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the Selling Securityholders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated. The Selling Securityholders do not expect these commissions and discounts to exceed what is customary in the types of transactions involved. Broker-dealers may agree to sell a specified number of such shares at a stipulated price per share, and, to the extent such broker-dealer is unable to do so acting as agent for us or a Selling Securityholder, to purchase as principal any unsold shares at the price required to fulfill the broker-dealer commitment. Broker-dealers who acquire shares as principal may thereafter resell such shares from time to time in transactions, which may involve block transactions and sales to and through other broker-dealers, including transactions of the nature described above, in the over-the-counter markets or otherwise at prices and on terms then prevailing at the time of sale, at prices than related to the then-current market price or in negotiated transactions. In connection with such resales, broker-dealers may pay to or receive from the purchasers such shares commissions as described above.

        The Selling Securityholders may from time to time pledge or grant a security interest in some or all of the common shares or Warrants owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the common shares from time to time under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act of 1933 amending the list of Selling Securityholders to include the pledgee, transferee or other successors in interest as Selling Securityholders under this prospectus.

        The Selling Securityholders also may transfer the common shares in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

        The Selling Securityholders and any broker-dealers or agents that are involved in selling the shares may be deemed to be "underwriters" within the meaning of the Securities Act in connection with such

19



sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. The Selling Securityholders have informed us that none of them have any agreement or understanding, directly or indirectly, with any person to distribute the common shares.

        We are required to pay all fees and expenses incurred by us incident to the registration of the shares. We have agreed to indemnify the Selling Securityholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.
