BUSINESS Overview PART I Plexus Corp. and its subsidiaries (together “Plexus,” the “Company,” or “we”) participate in the Electronic Manufacturing Services (“EMS”) industry. We partner with our customers to create the products that build a better world. Since 1979, Plexus has been partnering with companies to transform concepts into branded products and deliver them to the market. From idea to aftermarket and everything in between, Plexus is a global leader in providing support for all the facets of the product realization process – Design and Development, Supply Chain Solutions, New Product Introduction, Manufacturing, and Aftermarket Services. Plexus delivers comprehensive end-to-end solutions in the Americas (“AMER”), Europe, Middle East, and Africa (“EMEA”) and Asia-Pacific (“APAC”) regions for our customers. We specialize in working in industries with highly complex products and demanding regulatory requirements. Plexus has partnerships with approximately 140 customers in the Healthcare/Life Sciences, Industrial/ Commercial, Communications, and Aerospace/Defense market sectors. We leverage our expertise to understand the unique needs of our customers’ markets and have aligned our processes to provide flexibility, create efficiency and deliver superior quality. Our customers have stringent quality, reliability and regulatory requirements, requiring exceptional production and supply chain agility. Their products require complex logistics management and configuration management, direct order fulfillment (to end customers), global aftermarket services. To service the complexities that our customers’ products demand, we utilize our full suite of solution offerings to support our customers’ products from concept to end of life. Plexus is passionate about being the leading EMS company in the world at servicing mid-to-low volume, higher complexity customer programs, characterized by unique flexibility, technology, quality and regulatory requirements. To deliver on our strategy, we align our operations, processes, workforce and financial metrics to create: • A high performance, accountable organization with a talented workforce that is deeply passionate about driving growth through customer service excellence; • Strategic growth by using customer driven, sector based go-to-market strategies; and • Execution driven by a collaborative, customer centric culture that continuously evaluates and optimizes our business processes to strive to create shareholder value. We operate flexible manufacturing facilities and design our processes to accommodate customers with multiple product lines and configurations. One or more uniquely configured “focus factories,” supported by a tailored supply chain and logistics solution, are designed to meet the flexibility and responsiveness needed to support customer fulfillment requirements. We accomplish our go-to-market strategy through the four market sectors we serve. Each sector has a market sector vice president and a business development and customer management leader who together oversee and provide leadership to teams that include business development directors, customer directors or managers, supply chain and manufacturing subject matter experts, and market sector analysts. These teams maintain expertise related to each market sector and execute sector strategies aligned to that market’s unique quality and regulatory requirements. Our market sector teams help define Plexus’ strategy for growth with a particular emphasis on expanding the value-added solutions we offer customers. Our sales and marketing efforts focus on targeting new customers and expanding business with existing customers. We believe our ability to provide a full range of product realization services gives us a business advantage. 4 Our financial model aligns with our business strategy. Our primary focus is to earn a return on invested capital (“ROIC”) 500 basis points above our weighted average cost of capital (“WACC”), which we refer to as “Economic Return.” We review our internal calculation of WACC annually; for fiscal 2018, our WACC was 9.5%. We believe economic profit is a fundamental driver of shareholder value. Plexus measures economic profit by taking the difference between ROIC and WACC and multiplying it by invested capital. By exercising discipline to generate a ROIC in excess of our WACC, with focus on economic profit, our goal is to ensure that we create value for our shareholders. For more information regarding ROIC and Economic Return, which are non-GAAP financial measures, refer to “Management’s Discussion and Analysis of Financial Condition – Results of Operations – Return on Invested Capital (“ROIC”) and Economic Return” in Part II, Item 7. For a reconciliation of ROIC and Economic Return to our financial statements that were prepared using accounting principles generally accepted in the U.S. (“U.S. GAAP” or “GAAP”), see Exhibit 99.1 to this annual report on Form 10-K, which exhibit is incorporated herein by reference. Relative to our competition, overriding factors such as lower manufacturing volumes, flexibility and fulfillment requirements, and complex regulatory requirements typically result in higher investments in inventory and selling and administrative costs for us. The cost variance from our competitors is especially evident relative to those that provide EMS services for high-volume, less complex products, with less stringent requirements (e.g., consumer electronics). Plexus serves a diverse customer landscape that includes industry-leading, branded product companies, along with many other technology pioneering start-ups or emerging companies that may or may not maintain manufacturing capabilities. As a result of serving market sectors that rely on advanced electronics technology, our business is influenced by critical technological trends such as the level and rate of development of wired and wireless telecommunications infrastructure, communications data and data bandwidth growth, and internet usage. In addition to prime technology advancements, key government and policy trends impact our business, including the U.S. Food and Drug Administration’s (“FDA”) approval of new medical devices, defense procurement practices, and other government and regulatory processes. Plexus may benefit from increasing outsourcing trends. We provide most of our optimized solutions on a turnkey basis, and we procure some or all materials required for product assembly. We provide select services on a consignment basis, meaning the customer supplies the necessary materials and Plexus provides the labor and other services required for product assembly. In addition to manufacturing, turnkey service requires material procurement and warehousing and involves greater resource investments than consignment services. Other than certain test equipment, manufacturing equipment and software used for internal operations, we do not design or manufacture our own proprietary products. Established in 1979 as a Wisconsin corporation, we have over 18,000 employees, including over 3,500 engineers and technologists dedicated to product development and design, test equipment development and design, and manufacturing process development and control, all of whom operate from 23 active facilities, totaling approximately 3.5 million square feet. Plexus’ facilities are strategically located to support the global supply chain, engineering, manufacturing, and Aftermarket Service needs of customers in our targeted market sectors. Plexus maintains a website at www.plexus.com. As soon as is reasonably practical, after we electronically file or furnish all reports to the Securities and Exchange Commission (“SEC”), we provide online copies, free of charge. These reports include: Proxy Statements, Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K, Specialized Disclosure Reports on Form SD, and amendments to those reports. These reports are also accessible at the SEC’s website at www.sec.gov. Our Code of Conduct and Business Ethics is also posted on our website. You may access these SEC reports and the Code of Conduct and Business Ethics by following the links under “Investors” at our website. 5 Solutions With integrated Design and Development, Supply Chain Solutions, New Product Introduction, Manufacturing and Aftermarket Services, we proactively tackle tough challenges throughout the product lifecycle.

We have capabilities to assemble finished medical devices meeting FDA Quality Systems Regulation requirements and similar regulatory requirements in other countries. We have additional certifications and/or registrations held by certain facilities in the following regions: Medical Standard ISO 13485:2016 21 CFR Part 820 (FDA) (Finished Medical) JMGP accreditation GMP-Korea certification ANVISA accreditation Environmental Standard ISO - 14001 Environmental Standard OSHAS 18001 ANSI/ESD (Electrostatic Discharge Control Program) S20.20 ITAR (International Traffic and Arms Regulation) self-declaration Aerospace Standard AS9100 NADCAP certification FAR 145 certification (FAA repair station) EASA repair approval ATEX/IECEx certification IRIS certification (Railway) ISO 50001:2011 (energy management) AMER APAC EMEA X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X Customers and Market Sectors Served Our customers range from large multinational companies to smaller emerging technology companies. During fiscal 2018, we served approximately 140 customers. We offer advanced design and production capabilities, allowing our customers to concentrate on their core competencies. Plexus helps accelerate our customers’ time to market, reduce their investment in engineering and manufacturing capacity, and optimize total product cost. General Electric Company (“GE”) accounted for 12.3% of our net sales during fiscal 2018. GE accounted for 12.2% of our net sales in fiscal 2017. GE, Micron Technology, Inc. (“Micron”) and ARRIS Group, Inc. (“Arris”) accounted for 11.1%, 10.4%, and 10.1%, respectively, of our net sales in fiscal 2016. No other customers accounted for 10.0% or more of our net sales in any of the last three fiscal years. Net sales to our largest customers may vary from time to time depending on the size and timing of customer program commencements, terminations, delays, modifications and transitions. We generally do not obtain firm, long-term purchase commitments from our customers. Customers’ forecasts can and do change as a result of changes in their end-market demand and other factors, including global economic conditions. Any material change in forecasts or orders from these major accounts, or other customers, could materially affect our results of operations. The loss of any major customer could have a significant negative impact on our financial results. In addition, as our percentage of net sales to customers in a specific sector becomes larger relative to other sectors, we will become increasingly dependent upon the economic and business conditions affecting that sector. Many of our large customers contract with us through multiple independent divisions, subsidiaries, production facilities or locations. We believe that in most cases our sales to any one such division, subsidiary, facility or location are independent of sales to others. 7 The distribution of our net sales by market sectors for the indicated fiscal years is shown in the following table: Industry 2018 2017 2016 Healthcare/Life Sciences Industrial/Commercial Communications Aerospace/Defense 36% 32% 16% 16% 34% 31% 19% 16% 31% 30% 23% 16% Total net sales 100% 100% 100% Although our current business development focus is based on our targeted market sectors, we evaluate our financial performance and allocate our resources geographically (see Note 11 in Notes to Consolidated Financial Statements regarding our reportable segments). Plexus offers a uniform array of services for customers in each market sector and we do not dedicate operational equipment, personnel, facilities or other resources to particular market sectors, nor internally track our costs and resources per market sector. Materials and Suppliers We typically purchase raw materials, including PCBs and electronic components, from manufacturers and distributors. Under certain circumstances, we will purchase components from brokers, customers or competitors. The key electronic components we purchase include: specialized components (such as application-specific integrated circuits), semiconductors, interconnect products, electronic subassemblies (including memory modules, power supply modules and cable and wire harnesses), inductors, resistors and capacitors. We also purchase non-electronic, typically custom engineered, components used in manufacturing and higher- level assembly. These components include molded/formed plastics, sheet metal fabrications, aluminum extrusions, robotics, motors, vision sensors, motion/actuation, fluidics, displays, die castings and various other hardware and fastener components. These components are sourced from both Plexus preferred suppliers and customer directed suppliers. Components range from standard to highly customized and vary widely in terms of market availability and price. Component shortages and subsequent allocations by our suppliers are an inherent risk to the electronics industry, and have particularly been an issue for us and the industry from time to time, including during fiscal 2018. We discuss the causes of these shortages more fully in “Risk Factors” in Part I, Item 1A herein. We actively manage our business to minimize our exposure to material and component shortages. Plexus’ global supply chain management organization attempts to create strong supplier alliances and ensure a steady flow of components and products at competitive prices. We strive to achieve these goals through advanced supply chain solutions we develop in partnership with our customers, risk management tools and global expediting processes. Plexus can often influence the selection of new product components when engaged to provide design and development solutions. Competition Plexus operates in a highly competitive market, with a goal to be best-in-class at meeting the unique needs of our customers. We provide flexible solutions, timely order fulfillment, strong engineering, testing and production capabilities, and aftermarket services. A number of competitors may provide electronics manufacturing and engineering services similar to Plexus. Others may be more established in certain industry sectors, or have greater financial, manufacturing or marketing resources. Smaller competitors compete mainly in specific sectors and within limited geographic areas. Plexus also competes with in-house capabilities of current and potential customers. Plexus maintains awareness and knowledge of our competitors’ capabilities, in order to remain highly competitive within the broad scope of the EMS industry. 8 Intellectual Property We own various service marks that we use in our business, which are registered in the trademark offices of the United States and other countries. Although we own certain patents, they are not currently material to our business. We do not have any material copyrights. Information Technology Our core solutions for manufacturing facilities include a single-instance Enterprise Resource Planning (“ERP”) system, as well as Product Data Management and Advanced Planning and Scheduling systems, along with consistent solutions for warehouse management and shop floor execution, that support our global operations. This consistency augments our other management information systems, allowing us to standardize our ability to translate data from multiple production facilities into operational and financial information required by the business. The related software licenses are of a general commercial character on terms customary for these types of agreements. Enhancing cybersecurity continues to be a priority and we have several initiatives underway that are intended to further advance our security posture. Environmental Compliance We are subject to a variety of environmental regulations relating to air emission standards and the use, storage, discharge and disposal of hazardous chemicals used during our manufacturing process. We believe that we are in laws and do not anticipate any significant compliance with all federal, state and foreign environmental expenditures in maintaining our compliance; however, there can be no assurance that violations will not occur which could have a material adverse effect on our financial results. Social Responsibility Plexus is committed to social responsibility throughout our global business operations. Our commitment to social responsibility extends to human rights, labor practices, the environment, worker health and safety, fair operating practices and the Company’s social impact in the communities where we operate. We consider a variety of standards for socially responsible practices, including local and federal legal requirements in the jurisdictions where we operate, the International Organization for Standardization’s “Guidance on Social Responsibility” (ISO 26000) and standards established by the Responsible Business Alliance (the “RBA”). Plexus is a member of the RBA. Information about our corporate social responsibility efforts is available on our website at www.plexus.com. Employees We make a considerable effort to maintain a highly-qualified and engaged work force. We have been able to offer enhanced career opportunities to many of our employees. Our human resources department identifies career objectives and monitors specific skill development opportunities for employees with potential for advancement. We invest at all levels of the organization to ensure that employees are well trained and qualified for their positions. We have a policy of involvement and consultation with employees at every facility and strive for continuous improvement at all levels. We employ over 18,000 employees. Given the quick response times required by our customers, we seek to maintain flexibility to scale our operations as necessary to maximize efficiency. To do so we use skilled temporary labor in addition to our full-time employees. Approximately 300 and 1,000 of our employees are covered by union agreements in the United Kingdom and Mexico, respectively. These union agreements are typically renewed at the beginning of each year, although in a few cases these agreements may last two or more years. Our employees in China, Germany, Malaysia, Romania and the United States are not covered by union agreements. We have no history of labor disputes at any of our facilities, and we believe that our employee relationships are generally positive and stable. 9 ITEM 1A. RISK FACTORS Our net sales and operating results may vary significantly from period to period. Our quarterly and annual results may vary significantly depending on various factors, many of which are beyond our control. These factors include: • • • • • • • • • • • • • • • • • • • • the volume and timing of customer demand relative to our capacity the effects of shortages and delays in obtaining components as a result of economic cycles, natural disasters or otherwise the life-cycle of our customers’ technology-dependent products customers’ operating results and business conditions failure of our customers to pay amounts due to us changes in our, and our customers’, sales mix, as well as the volatility of these changes variations in sales and margins among geographic regions and market sectors changes in tariffs, trade agreements and other trade protection measures varying gross margins among different programs, including as a result of pricing concessions to certain customers claims alleging defective goods or services or breaches of contractual requirements challenges associated with the engagement of new customers or additional programs or services for existing customers disengagements with customers changes in customer supply chain strategies the timing of our expenditures in anticipation of future orders our effectiveness in planning and executing production, and managing inventory, fixed assets and manufacturing processes changes in the cost and availability of labor and components changes in exchange rates changes in accounting rules changes in tax laws, potential tax disputes, or negative or unforeseen tax consequences, and changes in U.S. and global economic and political conditions and world events. The majority of our net sales come from a relatively small number of customers and a limited number of market sectors; if we lose a major customer or if there are challenges in those market sectors, our net sales and operating results could decline significantly. Net sales to our ten largest customers have represented a majority of our net sales in recent periods. Our ten largest customers accounted for 57.2% of our net sales for the fiscal year ended September 29, 2018, and 55.5% of our net sales for the fiscal year ended September 30, 2017. During each of the fiscal years ended September 29, 2018, and September 30, 2017, there was one customer that represented 10.0% or more of our net sales. Our major customers may vary from period to period, and our major customers may not continue to purchase services from us at current levels, or at all, particularly given the volatile nature of certain programs. In any given period, a higher portion of our sales may be concentrated with customers or projects with relatively lower 10 margins, which could adversely affect our results. We have experienced from time to time, and in the future may experience, significant disengagements with customers or of programs, adverse changes in customer supply chain strategies and the end of life of significant programs. Especially given our discrete number of customers, significant reductions in net sales to any of our major customers, the loss of major customers or our failure to make appropriate choices as to the customers we serve could seriously harm our business and results of operations in such periods. In addition, we focus our sales efforts on customers in only a few market sectors. Each of these sectors is subject to macroeconomic conditions as well as trends and conditions that are sector specific. Economic, business or regulatory conditions that affect the sector, or the Company’s failure to choose appropriate sectors, can particularly impact Plexus. For instance, sales in the Healthcare/Life Sciences sector are substantially affected by trends in the healthcare industry, such as government reimbursement rates and uncertainties relating to the financial health of, and changes in the structure of, the U.S. healthcare sector generally. Additionally, the semiconductor industry has historically been subject to significant cyclicality and volatility. Further, potential reductions in U.S. government agency spending, including those due to budget cuts or other political developments or issues, could affect opportunities in all of our market sectors. Any weakness in our customers’ end markets could affect our business and results of operations. We rely on timely and regular payments from our customers; therefore, deterioration in the payment experience with or credit quality of our major customers could have a material adverse effect on our financial condition and results of operations. The inability or failure of our major customers to meet their obligations to us or their bankruptcy, insolvency or liquidation may adversely affect our business, financial condition and results of operations. From time to time, our customers, including formerly major customers, have been affected by merger, acquisition, divestiture and spin-off activity. While these transactions may present Plexus with opportunities to capture new business, they also create the risk that these customers will partially reduce their purchases or completely disengage from us as a result of transitioning such business to Plexus’ competitors or deciding to manufacture the products internally. Plexus is a multinational corporation and operating in multiple countries exposes us to increased risks, including adverse local developments and currency risks. We have operations in many countries; operations outside of the U.S. in the aggregate represent a majority of our net sales and operating income, with a particular concentration in Malaysia. In addition, although we repatriated $431.2 million of cash during fiscal 2018, a significant amount of our cash balances remain held outside of the U.S., with a particular concentration in Malaysia and China. We purchase a significant number of components manufactured in various countries. These international aspects of our operations, which are likely to increase over time, subject us to the following risks that could materially impact our operations and operating results: • • • • • • economic, political or civil instability transportation delays or interruptions exchange rate fluctuations potential disruptions or restrictions on our ability to access cash amounts held outside of the U.S. changes in labor markets, such as government-mandated wage increases, increases to minimum wage requirements, limitations on immigration or the free movement of labor or restrictions on the use of migrant workers, and difficulties in appropriately staffing and managing personnel in diverse cultures compliance with laws, such as the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act and the E.U. General Data Protection Regulation, applicable to companies with global operations 11 • • • • • • • changes to the North American Free Trade Agreement (“NAFTA”), including as a result of the expected approval of the United States-Mexico-Canada Agreement (the “USMCA”) changes in the taxation of earnings both in the U.S. and in other countries reputational risks related to, among other factors, varying standards and practices among countries changes in duty rates significant natural disasters and other events or factors impacting local infrastructure the impact of the United Kingdom’s pending exit from the European Union (“Brexit”) the effects of other international political developments, such as tariffs, embargoes, sanctions, boycotts, trade wars, energy disruptions, trade agreements and changes in trade policies, including those which may be effected by the current U.S. presidential administration and other countries’ reactions to those actions, and • regulatory requirements and potential changes to those requirements. We continue to monitor our risk associated with foreign currency and have entered into limited forward contracts to address this risk. As our international operations continue to expand, our failure to appropriately address foreign currency transactions or the currency exposures associated with assets and liabilities denominated in non-functional currencies could adversely affect our consolidated financial condition, results of operations and cash flows. In addition, developments affecting particular countries can adversely affect our ability to access cash or other assets held in such countries. A significant portion of our operations currently occurs in the APAC region, particularly in Malaysia. The Malaysian government is currently undergoing a period of transition, and while this may present new opportunities, changes in the Malaysian political climate could be challenging. The concentration of our operations, assets and profitability in that region exposes us to adverse developments, economic, political or otherwise, in those countries. Changes in policies by the U.S. or other governments could negatively affect our operating results due to trade wars, changes in duties, tariffs or taxes, currency exchange rate fluctuations, or limitations on currency or fund transfers, as well as government-imposed restrictions on producing certain products in, or shipping them to, specific countries. For example, potential changes in NAFTA, including as a result of the USMCA or otherwise, could adversely affect our operations in Mexico. Also, our current facilities in Mexico operate under the Mexican Maquiladora (“IMMEX”) program. This program provides for reduced tariffs and eased import regulations. We could be adversely affected by changes in the IMMEX program or our failure to comply with its requirements. Additionally, increasing tariffs and other trade protection measures between the U.S. and China may affect the cost of our products originating in China as well as the demand for our products manufactured in China in the event our customers reduce operations in China as a result of such tariffs or trade protection measures. These actions could also affect the cost and/or availability of components that we procure from suppliers in China. The United Kingdom’s pending exit from the European Union has resulted in currency exchange rate fluctuations and volatility. The terms of Brexit are not yet known. Given the lack of comparable precedent, the implications of Brexit, or how such implications might affect the Company (which also has operations in Scotland), remain unclear at this time. Brexit could, among other impacts, disrupt trade and the movement of goods, services and people between the United Kingdom and the European Union or other countries, disrupt the stability of the European Union generally, as well as create legal, political and global economic uncertainty. These and other potential implications could adversely affect the Company’s business and financial results. Our customers do not make long-term commitments and may cancel or change their production requirements. Companies in our industry must respond quickly to the requirements of their customers in both design and production. We generally do not obtain firm, long-term purchase commitments from our customers, and 12 frequently do not have visibility as to their future demand. Customers also cancel requirements, change engineering or other service requirements, change production quantities, delay production, or revise or fail to meet their forecasts for a number of reasons that are beyond our control, and customer expectations can change requiring us to take on additional commitments or risks. In addition, customers may also fail to meet their commitments to us or our expectations. The success of our customers’ products in the market and the strength of the markets themselves affect our business. Cancellations, reductions or delays by a significant customer, or by a group of customers, could seriously harm our operating results and negatively affect our working capital levels. Such cancellations, reductions or delays have occurred from time to time and may continue to occur in the future. In addition, we make significant decisions based on our estimates of customers’ requirements, including determining the levels of business that we will seek and accept, production schedules, component procurement commitments, working capital (including inventory) management, facility and capacity requirements, personnel needs and other resource requirements. The short-term nature of our customers’ commitments and the possibility of rapid changes in demand for their products reduce our ability to accurately estimate their future requirements. Because certain of our operating expenses are fixed, a reduction in customer demand can harm our operating results. The need for us to correctly anticipate component needs is amplified in times of shortages. The current environment of tight component supply can increase the difficulties and cost of anticipating changing demand. Moreover, because our margins vary across customers and specific programs, a reduction in demand with higher margin customers or programs will have a more significant adverse effect on our operating results. Rapid increases in customer requirements may stress personnel and other capacity resources. We may not have sufficient resources, including personnel and components, at any given time to meet all of our customers’ demands or to meet the requirements of a specific program, which could result in a loss of business from such customers. We have a complex business model, and our failure to properly manage or execute on that model, as well as an inability to maintain our engineering, technological and manufacturing process expertise, could adversely affect our operations, financial results and reputation. Our business model focuses on products and services in the mid-to-low-volume, higher-complexity segment of our industry. Our customers’ products typically require significant production and supply-chain flexibility, in some cases necessitating optimized demand-pull-based manufacturing and supply chain solutions across an integrated global platform. The products we manufacture are also typically complex, heavily regulated, and require complicated configuration management and direct order fulfillment capabilities to global end customers. In addition, we offer Aftermarket Services to our customers, which add to the complexity of our business model. Our business model requires a great degree of attention, flexibility and resources. These resources include working capital, management and technical personnel, and the development and maintenance of systems and procedures to manage diverse manufacturing, regulatory and service requirements for multiple programs of varying sizes simultaneously, including in multiple locations and geographies. We also depend on securing and ramping new customers and programs and on transitioning production for new customers and programs, which creates added complexities related to managing the start-up risks of such projects, especially for companies that did not previously outsource such activities. The complexity of our service model, which encompasses a broad range of services including conceptualization, design, commercialization, manufacturing, fulfillment and Aftermarket Services, often results in complex and challenging contractual obligations as well as commitments from us to our customers. In addition, customer expectations have also increased in recent years with respect to certain capabilities and commitments. If we fail to meet those obligations or are otherwise are unable to execute on our commitments, it could result in claims against us or adversely affect our reputation and our ability to obtain future business, as well as impair our ability to enforce our rights (including those related to payment) under those contracts. 13 If we fail to effectively manage or execute our business model, we may lose customer confidence and our reputation may suffer. The Company’s reputation is the foundation of our relationships with key stakeholders. If we are unable to effectively manage real or perceived issues, which could negatively impact sentiments toward the Company, our ability to maintain or expand business opportunities could be impaired and our financial results could suffer on a going-forward basis. Many of the markets for our manufacturing, engineering, aftermarket and other services are characterized by rapidly changing technology and evolving process developments. Our internal processes are also subject to these factors. The continued success of our business will depend upon our continued ability to: • retain our qualified engineering and technical personnel, and attract additional qualified personnel • maintain and enhance our technological capabilities • • • • • choose and maintain appropriate technological and service capabilities successfully manage the implementation and execution of information systems develop and market services that meet changing customer needs effectively execute our services and perform to our customers’ expectations, and successfully anticipate, or respond to, technological changes on a cost-effective and timely basis. Although we believe that our operations utilize the assembly and testing technologies, equipment and processes that are currently required by our customers, we cannot be certain that we will maintain or develop the capabilities required by our customers in the future. The emergence of new technologies, industry standards or inventory or processes obsolete or noncompetitive. In customer requirements may render our equipment, addition, we may have to acquire new design, assembly and testing technologies and equipment to remain competitive, as well as offer new or additional services, all of which may require significant expense or capital investment that could reduce our liquidity and negatively affect our operating results. Our failure to anticipate and adapt to our customers’ changing technological needs and requirements, or to perform to their expectations or standards, as well as our need to maintain our personnel and other resources during times of fluctuating demand, could have an adverse effect on our business. We experience raw material and component shortages and price fluctuations. We generally do not have long-term supply agreements. We experience, and in the future will likely continue to experience, raw material and component shortages due to supplier capacity constraints, or their failure to deliver. We also experience increased lead times to procure certain types of components. Such constraints can also be caused by world events, such as government policies, tariffs, trade wars and trade protection measures, terrorism, armed conflict, natural disasters, economic recession, increased demand due to economic growth, preferential allocations and other localized events. We currently rely on a limited number of suppliers for many of the raw materials and components used in the assembly process and, in some cases, may be required to use suppliers that are the sole provider of a particular raw material or component. Such suppliers may encounter quality problems, labor disputes, financial difficulties or business continuity issues that could preclude them from delivering raw materials or components timely or at all. Supply shortages and delays in deliveries of raw materials or components have in some cases resulted in delayed production of assemblies, which have increased our inventory levels and adversely affected our operating results in certain periods. Additionally, a delay in obtaining a particular component may result in other components for the related project being held for longer periods of time, increasing working capital and risking inventory obsolescence. An inability to obtain sufficient inventory on a timely basis could also harm relationships with our customers. In addition, raw materials and components that are delivered to us may not meet our specifications or other quality criteria. Certain materials provided to us may be counterfeit or violate the intellectual property rights of 14 others. The need to obtain replacement materials and parts may negatively affect our manufacturing operations. The inadvertent use of any such parts or products may also give rise to liability claims. Raw material and component supply shortages and delays in deliveries, along with other factors such as tariffs and trade disputes, can also result in increased pricing. While many of our customers permit quarterly or other periodic adjustments to pricing based on changes in raw material or component prices and other factors, we may bear the risk of price increases that occur between any such repricing or, if such repricing is not permitted, during the balance of the term of the particular customer contract. Conversely, as a result of our pricing strategies and practices, raw material and component price reductions have contributed positively to our operating results in the past. Our inability to continue to benefit from such reductions in the future could adversely affect our operating results. Our services involve other inventory risk. Most of our services are provided on a turnkey basis, under which we purchase some, or all, of the required materials and components based on customer forecasts or orders. Suppliers may require us to purchase materials requirements. A customer’s and components in minimum order quantities that may exceed customer cancellation, delay or reduction of forecasts or orders can also result in excess inventory or additional expense to us. Engineering changes by a customer may result in obsolete materials or components. While we attempt to cancel, return or otherwise mitigate excess and obsolete inventory and require customers to reimburse us for these items, we may not actually be reimbursed timely or be able to collect on these obligations. In addition to increasing inventory in certain instances to support new program ramps, we may also increase inventory if we experience component shortages or longer lead times for certain components in order to maintain a high level of customer service. In such situations, we may procure components earlier, which has led to an increase in inventory in the short term and may lead to increased, excess, or obsolete inventory in the future. Excess or obsolete inventory, the need to acquire increasing amounts of inventory due to shortages, customer demand or otherwise, or other failures to manage our working capital, could adversely affect our operating results, including our return on invested capital. In addition, we provide managed inventory programs for some of our customers under which we hold and manage finished goods or work-in-process inventories. These managed inventory programs result in higher inventory levels, further reduce our inventory turns and increase our financial exposure with such customers. In addition, our inventory may be held at a customer’s facility or warehouse, or elsewhere in a location outside of our control, which may increase the risk of loss. Even though our customers generally have contractual obligations to purchase such inventories from us, we remain subject to customers’ credit risks as well as the risk of potential customer default and the need to enforce those obligations. Our products and services are for end markets that require technologically advanced products. Factors affecting the technology-dependent end markets that we serve could adversely affect our customers and, as a result, Plexus. These factors include: • • • • the inability of our customers to adapt standards that can result in short product life-cycles to rapidly changing technologies and evolving industry the inability of our customers to develop and market their products, some of which are new and untested the potential that our customers’ products may become obsolete, and the potential failure of our customers’ products to gain widespread commercial acceptance. Even if our customers successfully respond to these market challenges, including any consequential changes we must make in our business relationships with them and our production for, or services their responses, 15 offered to, them, or to our supply chain for related components, can affect our production cycles, inventory management and results of operations. Challenges associated with the engagement of new customers or programs, or the provision of new services, could affect our operations and financial results. Our engagement with new customers, as well as the addition of new programs or types of services for existing customers, can present challenges in addition to opportunities. We must initially determine whether it would be in our interests from a business perspective to pursue a particular potential new customer, program or service, including evaluating whether the customer, program or service fits with our value proposition as well as its potential end-market success. If we make the decision to proceed, we need to ensure that our terms of engagement, including our pricing and other contractual provisions, appropriately reflect the anticipated costs, risks and rewards. The failure to make prudent engagement decisions or to establish appropriate terms of engagement could adversely affect our profitability and margins. Also, there are inherent risks associated with the timing and ultimate realization of anticipated revenue from a new program or service; these factors can sometimes extend for a significant period. Some new programs or services require us to devote significant capital and personnel resources to new technologies and competencies. We may not meet customer expectations, which could damage our relationships with the affected customers and impact our ability to deliver conforming product or services on a timely basis. Further, the success of new programs may depend heavily on factors such as product reliability, market acceptance, regulatory approvals or economic conditions. The failure of a new program to meet expectations on these factors, or our inability to effectively execute on a new program’s or service’s requirements, could result in lost financial opportunities and adversely affect our results of operations. Start-up costs and inefficiencies related to new, recent or transferred programs can adversely affect our operating results. In recent years, ramping new program wins has been a key contributor to our revenue growth. The management of resources in connection with the establishment of new or recent programs and customer relationships, as well as program transfers between facilities and geographies, and the need to estimate required resources in advance of production can adversely affect our gross and operating margins and level of working capital. These factors are particularly evident in the early stages of the life-cycle of new programs, which typically lack a track record of order volume and timing as well as production efficiencies in the early stages. We typically manage multiple new programs at any given time; therefore, we are exposed to these factors in varying magnitudes. In addition, if any of these programs or customer relationships were delayed or terminated, our operating results could be negatively impacted, particularly in the short-term. The effects of these start-up costs and inefficiencies can also occur when we transfer programs between locations and geographies. We conduct these transfers on a regular basis to meet customer needs, seek long-term efficiencies or respond to market conditions, as well as due to facility openings and closures. We may also be required to transfer projects between facilities due to trade measures impacting particular countries such as China. Although we try to recover costs from our customers and minimize the potential losses arising from transitioning customer programs between our facilities and geographies, we may not be successful and there are inherent risks that such transitions can result in operational inefficiencies and the disruption of programs and customer relationships. While these factors tend to affect new, recent or transferred programs, they can also impact more mature, or maturing programs and customer relationships, especially programs where end-market demand can be somewhat volatile. 16 Failure to manage periods of growth or contraction may seriously harm our business. Our industry frequently sees periods of expansion and contraction. We regularly contend with these issues and must carefully manage our business to meet changing customer and market requirements. If we fail to manage these growth and contraction decisions effectively, as well as fail to realize the anticipated benefits of these decisions, we can find ourselves with either excess or insufficient resources and our business, as well as our profitability, may suffer. Expansion and consolidation, including the transfer of operations to new or other facilities or due to acquisitions, can inherently include additional costs and start-up inefficiencies. For example, we are in the process of bringing online additional facilities in Guadalajara, Mexico and Penang, Malaysia, which are expected to be completed in fiscal 2019 and are intended to supplement our footprint in those particular regions. If we are unable to effectively manage our recent or future expansions and consolidations, or related anticipated net sales are not realized, our operating results could be adversely affected. In addition, we may expand our operations in new geographical areas where currently we do not operate. Other risks of current or future expansions, acquisitions and consolidations include: • • • • • • • • • the inability to successfully integrate additional facilities or incremental capacity and to realize anticipated efficiencies, economies of scale or other value challenges faced as a result of transitioning programs incurrence of restructuring costs or other charges that may be insufficient or may not have their intended effects additional fixed or other costs, or selling, general and administrative (“SG&A”) expenses, which may not be fully absorbed by new business a reduction of our return on invested capital, including as a result of excess inventory or excess capacity at new facilities, as well as the increased costs associated with opening new facilities difficulties in the timing of expansions, including delays in the implementation of construction and manufacturing plans diversion of management’s attention from other business areas during the planning and implementation of expansions strain placed on our operational, financial and other systems and resources, and inability to locate sufficient customers, employees or management talent to support the expansion. Periods of contraction or reduced net sales, or other factors affecting particular sites, create other challenges. We must determine whether facilities remain viable, whether staffing levels need to be reduced, and how to respond to changing levels of customer demand. While maintaining excess capacity or higher levels of employment entail short-term costs, reductions in capacity or employment could impair our ability to respond to new opportunities and programs, market improvements or to maintain customer relationships. Our decisions to reduce costs and capacity can affect our short-term and long-term results. When we make decisions to reduce capacity or to close facilities, we frequently incur restructuring costs. In addition, to meet our customers’ needs, particularly when the production requirements of certain products are site-specific, to achieve increased efficiencies, or to address other factors affecting specific locations, we sometimes require additional capacity in one location while reducing capacity in another. Since customers’ needs and market conditions can vary and change rapidly, we may find ourselves in a situation where we simultaneously experience the effects of contraction in one location and expansion in another location. We may also encounter situations where our lack of a physical presence in certain locations may limit or foreclose opportunities. 17 An inability to successfully manage the procurement, development, implementation or execution of information systems, or to adequately maintain these systems and their security, as well as to protect data and other confidential information, may adversely affect our business and reputation. As a global company with a complex business model, we are heavily dependent on our information systems to support our customers’ requirements and to successfully manage our business. In particular, we are currently in the process of upgrading our most significant ERP system and evaluating the replacement of other systems. Any inability to successfully manage the procurement, development, implementation, execution or maintenance of our information systems, including matters related to system and data security, cybersecurity, privacy, reliability, compliance, performance and access, as well as any inability of these systems to fulfill their intended purpose within our business, could have an adverse effect on our business. In the ordinary course of business, we collect and store sensitive data and information, including our proprietary and regulated business information and that of our customers, suppliers and business partners, as well as personally identifiable information about our employees. Our information systems, like those of other companies, are susceptible to malicious damage, intrusions and outages due to, among other events, viruses, cyber threats, industrial espionage (internal or external), hacking, break-ins and similar events, other breaches of security, natural disasters, power loss or telecommunications failures. We have taken steps to maintain adequate data security and address these risks and uncertainties by implementing security technologies, internal controls, network and data center resiliency, redundancy and recovery processes, as well as by purchasing insurance; however, these measures may not be sufficient. Moreover, we are subject to increasing expectations and data security requirements from our customers, including those related to Federal Acquisition Regulation compliance. Any operational failure or breach of security from increasingly sophisticated cyber threats could lead to the loss or disclosure of our or our customers’ financial, product or other confidential information, result in adverse regulatory or other legal actions and have a material adverse effect on our business and reputation. In addition, we must comply with increasingly complex and rigorous regulatory standards enacted to protect business and personal data in the U.S. and elsewhere. For example, the European Union recently adopted the General Data Protection Regulation (the “GDPR”). The GDPR imposes additional obligations on companies regarding the handling of personal data and provides certain individual privacy rights to persons whose data is stored. Compliance with existing, proposed and recently enacted laws and regulations can be costly; any failure to comply with these regulatory standards could subject us to legal and reputational risks. Misuse of or failure to secure personal information could also result in violation of data privacy laws and regulations, proceedings against the Company by governmental entities or others, fines and penalties, damage to our reputation and credibility and could have a negative impact on our business and results of operations. Changes in tax laws, potential tax disputes, negative or unforeseen tax consequences or further developments affecting our deferred tax assets could adversely affect our results. The Company’s effective tax rate is highly dependent upon the geographic mix of earnings across the jurisdictions where we operate. Changes in tax laws or tax rates in those jurisdictions, including, but not limited to, as a result of actions by the U.S. (including additional guidance and interpretations related to U.S. Tax Reform) or other countries or Brexit, could continue to have a material impact on our operating results. Among other things, the Company will be affected by the global intangible low-taxed income provisions added by U.S. Tax Reform and related new tax legislation, interpretations and guidance. The Company’s effective tax rate may also be impacted by tax holidays and other various tax credits granted by local taxing authorities. In addition, the implementation of U.S. Tax Reform has required the use of estimates, which may be refined in future periods. All incentives, including a tax holiday granted to our Malaysian subsidiary, are subject to certain terms and conditions. While we expect to comply with these conditions, we would experience adverse tax consequences if we are found to not be in compliance or if the terms and conditions of the tax holiday are unfavorably altered by the local taxing authorities. 18 The Company’s taxable income in any jurisdiction is dependent upon the local taxing authority’s acceptance of our operational and intercompany transfer pricing practices as being at “arm’s length.” Due to inconsistencies among jurisdictions in the application of the arm’s length standard, the Company’s transfer pricing methods may be challenged and, if not upheld, could increase our income tax expense. Risks associated with transfer pricing adjustments are further highlighted by the global initiative from the Organisation for Economic Cooperation and Development (“OECD”) called the Base Erosion and Profit Shifting (“BEPS”) project. The BEPS project is challenging longstanding international tax norms regarding the taxation of profits from cross-border business. Given the scope of the Company’s international operations and the fluid and uncertain nature of how the BEPS project might ultimately lead to future legislation, it is difficult to assess how any changes in tax laws would impact the Company’s income tax expense. The Company reviews the probability of the realization of our net deferred tax assets each period based on forecasts of taxable income by jurisdiction. This review uses historical results, projected future operating results based upon approved business plans, eligible carryforward periods, tax planning opportunities and other relevant considerations. Adverse changes in the profitability and financial outlook in each of our jurisdictions may require the creation of an additional valuation allowance to reduce our net deferred tax assets. Such changes could result in material non-cash expenses in the period in which the changes are made. We and our customers are subject to increasingly extensive government regulations and industry standards; a failure to comply with current and future regulations and standards could have an adverse effect on our business, customer relationships, reputation and profitability. We are subject to extensive government regulation and industry standards (as well as customer-specific standards) relating to the products we design, manufacture and service as well as how we conduct our business, including regulations and standards relating to labor and employment practices, workplace health and safety, the environment, sourcing and import/export practices, the market sectors we support and many other facets of our operations. The regulatory climate in the U.S. and other countries has become increasingly complex and fragmented, and regulatory activity has increased in recent periods. A failure to comply with such regulations or standards could have an adverse effect on our reputation, customer relationships, profitability and results of operations. Particularly as a publicly-held company, we are subject to increasingly stringent laws, regulations and other requirements, including those affecting, among other areas, our accounting, internal controls, data protection and privacy, corporate governance practices, securities disclosures and reporting. Governments worldwide are becoming increasingly aggressive in adopting and enforcing anti-corruption laws. The U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act and China’s Criminal Law and Anti-Unfair Competition Law, among others, apply to us and our operations. Changes in healthcare laws and regulations may significantly affect the provision of both healthcare services and benefits in the U.S. and may impact our cost of providing our employees and retirees with health insurance or benefits, and may also impact various other aspects of our business, such as the demand for products in our Healthcare/Life Sciences sector. Our Healthcare/Life Sciences sector is subject to statutes and regulations covering the design, development, testing, manufacturing and labeling of medical devices and the reporting of certain information regarding their safety, including Food and Drug Administration (“FDA”) regulations and similar regulations in other countries. Failure to comply with these regulations can result in, among other things, fines, injunctions, civil penalties, criminal prosecution, recall or seizure of devices, or total or partial suspension of production. We also design, manufacture and service products for certain industries, including certain applications where the U.S. government is the end customer, that face significant regulation by the Department of Defense, Department 19 of State, Department of Commerce, Federal Aviation Authority, and other governmental agencies in the U.S. as well as in other countries, and also under the Federal Acquisition Regulation. In addition, whenever we pursue business in new sectors and subsectors, or our customers pursue new technologies or markets, we need to navigate the potentially heavy regulatory and legislative burdens of such sectors, as well as standards of quality systems, technologies or markets. The regulatory climate can itself affect the demand for our services. For example, government reimbursement rates and other regulations, as well as the financial health of healthcare providers, and changes in how healthcare in the U.S. is structured, and how medical devices are taxed, could affect the willingness and ability of end customers to purchase the products of our customers in this sector as well as impact our margins. Our customers are also required to comply with various government regulations, legal requirements and industry standards, including many of the industry-specific regulations discussed above. Our customers’ failure to comply could affect their businesses, which in turn would affect our sales to them. In addition, if our customers are required by regulation or other requirements to make changes in their product lines, these changes could significantly disrupt particular programs for these customers and create inefficiencies in our business. A failure to comply with customer-driven policies and standards, and third party certification requirements or standards, including those related to social responsibility, could adversely affect our business and reputation. In addition to government regulations and industry standards, our customers may require us to comply with their own or third party quality standards, business policies, commercial terms, or other social responsibility policies or standards, which may be more restrictive than current laws and regulations as well as our pre-existing policies, before they commence, or continue, doing business with us. Such policies or standards may be customer-driven, established by the industry sectors in which we operate or imposed by third party organizations. Our compliance with these heightened and/or additional policies, standards and third party certification requirements, and managing a supply chain in accordance therewith, could be costly, and our failure to comply could adversely affect our operations, customer relationships, reputation and profitability. In addition, our adoption of these standards could adversely affect our cost competiveness, ability to provide customers with required service levels and ability to attract and retain employees in jurisdictions where these standards vary from prevailing local customs and practices. In certain circumstances, to meet the requirements or standards of our customers we may be obligated to select certain suppliers or make other sourcing choices, and we may bear responsibility for adverse outcomes even if these matters are as the result of third party actions or outside of our control. Changes to financial accounting rules or standards, or challenges to our interpretation or application of the rules by regulators, may have a material adverse effect on our reported financial results or on the way we conduct business. We prepare our financial statements in conformity with U.S. GAAP. These principles are subject to interpretation by the Financial Accounting Standards Board (“FASB”), the SEC and various bodies formed to interpret and create accounting policies. From time to time, we are required to adopt new or revised accounting standards issued by recognized authoritative bodies, including the FASB and the SEC. For example, in 2014 the FASB issued new guidance that impacts revenue recognition criteria and is effective for the Company beginning in the first quarter of fiscal year 2019. The Company has determined that the new standard will result in a change to the timing of revenue recognition for a significant portion of the Company’s revenue stream, whereby revenue will be recognized “over time” as production occurs as opposed to at a “point in time” upon physical delivery. The new standard will have a material impact on the Company’s consolidated financial statements upon initial adoption, primarily as the Company recognizes an increase in contract assets for unbilled receivables with a 20 corresponding reduction in finished goods and work-in-process inventory. See also “Recently Issued Accounting Pronouncements Not Yet Adopted” within Note 1, “Description of Business and Significant Accounting Policies,” in Part II, Item 8, Notes to Consolidated Financial Statements for additional information regarding the impacts the new standard will have on the Company’s consolidated financial statements. The new standard is also expected to have an impact on the Company’s ability to forecast financial results in the near term as it begins to implement the standard. New controls have been adopted and more may be needed to comply with such changes, and we may fail to adequately implement the needed changes. There may be problems with the products we design, manufacture or service that could result in liability claims against us, reduced demand for our services and damage to our reputation. The products that we design, manufacture or service may be subject to liability or claims in the event that defects are discovered or alleged. We design, manufacture and service products to our customers’ specifications, many of which are highly complex, and produce products for industries, such as healthcare, aerospace and defense, that have higher risk profiles. Despite our quality control and quality assurance efforts, problems may occur, or may be alleged, in the design, manufacturing or servicing of these products, including as a result of business continuity issues. Whether or not we are responsible, problems in the products we manufacture, whether real or alleged, whether caused by faulty customer specifications, the design or manufacturing processes, servicing, or a component defect, may result in delayed shipments to customers or reduced or canceled customer orders. If these problems were to occur in large quantities or too frequently, our business reputation may also be tarnished. In addition, such problems may result in liability claims against us, whether or not we are responsible. These potential claims may include damages for the recall of a product or injury to person or property. Even if customers or third parties, such as component suppliers, are responsible for defects, they may not, or may not be able to, assume responsibility for any such costs or required payments to us. While we seek to insure against many of these risks, we may not have practical recourse against certain suppliers, and insurance coverage or supplier warranties may be inadequate, not cost effective or unavailable, either in general or for particular types of products or issues. We occasionally incur costs defending claims, and any such disputes could adversely affect our business relationships. Intellectual property infringement claims against our customers or us could harm our business. Our services and the products offered by our customers involve the creation and use of intellectual property rights, which subject us and our customers to the risk of claims of intellectual property infringement from third parties. In addition, our customers may require that we indemnify them against the risk of intellectual property infringement. If any claims are brought against us or our customers for infringement, whether or not these have merit, we could be required to expend significant resources in defense of those claims. In the event of an infringement claim, we may be required to spend a significant amount of money to develop non-infringing alternatives or obtain licenses. We may not be successful in developing alternatives or obtaining licenses on reasonable terms or at all. Infringement by our customers could cause them to discontinue production of some of their products, potentially with little or no notice, which may reduce our net sales to them and disrupt our production. Additionally, if third parties on whom we rely for products or services, such as component suppliers, are responsible for an infringement (including through the supply of counterfeit parts), we may or may not be able to hold them responsible and we may incur costs in defending claims or providing remedies. Such infringements may also cause our customers to abruptly discontinue selling the impacted products, which would adversely affect our net sales of those products, and could affect our customer relationships more broadly. Similarly, claims affecting our suppliers could cause those suppliers to discontinue selling materials and components upon which we rely. 21 Increased competition may result in reduced demand or reduced prices for our services. Our industry is highly competitive. We compete against numerous providers with global operations, as well as those which operate on only a local or regional basis. In addition, current and prospective customers continually evaluate the merits of designing, manufacturing and servicing products internally and may choose to design, manufacture or service products (including products or product types that we currently design, manufacture or service for them) themselves rather than outsource such activities. Consolidations and other changes in our industry may result in a changing competitive landscape. Our competitors may: • • • • • • • • respond more quickly than us to new or emerging technologies have greater name recognition, critical mass and geographic and market presence be better able to take advantage of acquisition opportunities adapt more quickly to changes in customer requirements have lower internal cost structures have greater direct buying power with component suppliers, distributors and raw material suppliers devote greater resources to the development, promotion and sale of their services and execution of their strategy, and be better positioned to compete on price for their services. Our manufacturing processes are generally not subject to significant proprietary protection, and companies with greater resources or a greater market presence may enter our market or otherwise become increasingly competitive. Increased competition could result in significant price reductions, reduced sales and margins, or loss of market share. We depend on our workforce, including certain key personnel, and the loss of key personnel or other personnel disruptions, including the inability to hire and retain sufficient personnel, may harm our business. Our success depends in large part on the continued services of our key management and technical personnel, and on our ability to attract, develop and retain qualified employees, particularly highly skilled design, process and test engineers involved in the development of new products and processes and the manufacture of products. The competition for these individuals is significant, and the loss of key employees could harm our business. From time to time, there are changes and developments, such as retirements, promotions, transitions, disability, death and other terminations of service that affect our executive officers and other key employees, including those that are unexpected. Transitions or other changes in responsibilities among officers and key employees, particularly those that are unanticipated, unplanned or not executed effectively, inherently can cause disruptions to our business and operations, which could have an effect on our results. We also depend on good relationships with our workforce generally. Any disruption in our relationships with our personnel, including as a result of potential union organizing activities, work actions or other labor issues, could substantially affect our operations and results. In addition, when we expand operations in either existing areas or new locations, including internationally, we need to attract and retain the services of sufficient qualified personnel to conduct those operations. If we fail to retain and maintain sufficient qualified personnel, the operations at those locations, and consequently our financial results, could be adversely affected. In new or existing facilities we may be subject to local labor practices or union activities, wage pressure and changing wage requirements, increasing healthcare costs, 22 differing employment laws and regulations in various countries, local competition for employees, restrictions on immigration, labor mobility as well as high turnover, and other issues affecting our workforce, all of which could affect operations at particular locations, which also could have adverse effects on our operational results. As noted above, our adoption of certain third-party standards could adversely affect our ability to attract and retain employees in jurisdictions where these standards vary from prevailing local customs and practices. Natural disasters, breaches of security and other events outside our control, and the ineffective management of such events, may harm our business. Some of our facilities are located in areas that may be impacted by natural disasters, including tornadoes, hurricanes, earthquakes, water shortages, tsunamis and floods. All facilities are subject to other natural or man-made disasters such as those related to weather events or global climate change, fires, acts of terrorism or war, breaches of security, theft or espionage, workplace violence and failures of utilities. If such an event was to occur, our business could be harmed due to the event itself or due to our inability to effectively manage the effects of the particular event, with the impact of the event potentially magnified in areas where we have multiple facilities. Potential harms include the loss of business continuity, the loss of business data and damage to infrastructure. In addition, some of our facilities possess certifications necessary to work on specialized products that our other locations lack. If work is disrupted at one of these facilities, it may be impractical or we may be unable to transfer such specialized work to another facility without significant costs and delays. Thus, any disruption in operations at a facility possessing specialized certifications could adversely affect our ability to provide products and services to our customers, and thus negatively affect our relationships and financial results. Although we have implemented policies and procedures with respect to physical security, we remain at risk of unauthorized access to our facilities and the possible unauthorized use or theft of inventory, information or other physical assets. If unauthorized persons gain physical access to our facilities, or our physical assets or information are stolen, damaged or used in an unauthorized manner (whether through outside theft or industrial espionage), we could be subject to, among other consequences, negative publicity, governmental inquiry and oversight, loss of government contracts, litigation by affected parties or other future financial obligations related to the loss, misuse or theft of our or our customers’ data, inventory or physical assets, any of which could have a material adverse effect on our reputation and results of operations. We may fail to secure or maintain necessary additional financing or capital. Although we have credit facilities, as described below, and successfully replaced our Senior Notes in fiscal 2018, we cannot be certain that our existing credit arrangements will provide all of the financing capacity that we will need in the future or that we will be able to change the credit facilities or revise covenants, if necessary, to accommodate changes or developments in our business and operations and/or increased working capital needs. In addition, if we do not comply with the covenants under our credit agreement, our ability to borrow under that facility would be adversely affected. In addition, it is possible that counterparties to our financial agreements, including our credit agreement and receivables factoring programs, may not be willing or able to meet their obligations, either due to instability in the global financial markets or otherwise. Our future success may depend on our ability to obtain additional financing and capital to support possible future growth and future initiatives. We have the potential to increase capacity under our revolving credit facility from $300 million to $500 million with the approval of the lenders. In addition, we also have receivables factoring programs. Many of our borrowings are at variable interest rates and therefore our interest expense is subject to increase if rates, including LIBOR, increase. We may seek to raise capital by issuing additional common stock, other equity securities or debt securities, modifying our existing credit facilities or obtaining new facilities, or through a combination of these methods. 23 We may not be able to obtain capital when we want or need it, and capital may not be available on satisfactory terms. If we issue additional equity securities or convertible securities to raise capital, it may be dilutive to shareholders’ ownership interests; we may not be able to offer our securities on attractive or acceptable terms in the event of volatility or weakness in our stock price. Furthermore, any additional financing may have terms and conditions that adversely affect our business, such as restrictive financial or operating covenants, and our ability to meet any current or future financing covenants will largely depend on our financial performance, which in turn will be subject to general economic conditions and financial, business and other factors. We may fail to successfully complete future acquisitions, as well as strategic arrangements, and may not successfully integrate acquired operations or recognize the anticipated benefits, which could adversely affect our operating results. We have previously grown, in part, through acquisitions and strategic arrangements, such as our fiscal 2018 acquisition of the assets of one of the business lines of Cascade Controls, Inc. (“Cascade”), a company that provides new product introduction services. If we were to pursue future growth through acquisitions, including the acquisition of operations divested by our customers, or similar transactions, this would involve significant risks that could have a material adverse effect on us. These risks include: Operating risks, such as: • • • • • • the inability to integrate successfully our acquired operations’ businesses, systems and personnel the inability to realize anticipated synergies, economies of scale or other value the difficulties in scaling up production and coordinating management of operations at new sites the strain placed on our personnel, systems and resources the possible modification or termination of an acquired business’ customer programs, including the loss of customers and the cancellation of current or anticipated programs, and the loss of key employees of acquired businesses. Financial risks, such as: • • • • • • • the use of cash resources, or incurrence of additional debt and related interest expense the dilutive effect of the issuance of additional equity securities the effect of potential volatility or weakness in our stock price on its use as consideration for acquisitions the inability to achieve expected operating margins to offset the increased fixed costs associated with acquisitions, or inability to increase margins of acquired businesses to our desired levels the incurrence of large write-offs or write-downs the impairment of goodwill and other intangible assets, and the unforeseen liabilities of the acquired businesses.

RESULTS OF OPERATIONS Consolidated Performance Summary. The following table presents selected consolidated financial data for the indicated fiscal years (dollars in millions, except per share data): Net sales Cost of sales Gross profit Gross margin Operating income Operating margin Other expense Income tax expense Net income Diluted earnings per share Return on invested capital* Economic return* 2018 2017 2016 $2,873.5 2,615.9 257.6 9.0% 118.3 4.1% 10.7 94.6 13.0 0.38 16.1% 6.6% $ $2,528.1 2,272.2 255.9 10.1% 129.9 5.1% 8.1 9.8 112.1 3.24 16.2% 5.7% $ $2,556.0 2,328.6 227.4 8.9% 99.4 3.9% 12.0 11.0 76.4 2.24 13.8% 2.8% $ * Non-GAAP metric; refer to “Return on Invested Capital (“ROIC”) and Economic Return” below for more information and Exhibit 99.1 for a reconciliation. Net sales. Fiscal 2018 net sales increased $345.4 million, or 13.7%, as compared to fiscal 2017. Fiscal 2017 net sales decreased $27.9 million, or 1.1%, as compared to fiscal 2016. Net sales are analyzed by management by geographic segment, which reflects the Company’s reportable segments, and by market sector. Management measures operational performance and allocates resources on a geographic segment basis. The Company’s global business development strategy is based on our targeted market sectors. 29 A discussion of net sales by reportable segment is presented below for the indicated fiscal years (in millions): Net sales: AMER APAC EMEA Elimination of inter-segment sales 2018 2017 2016 $1,218.9 1,498.0 281.5 (124.9) $1,166.4 1,279.3 192.8 (110.4) $1,328.8 1,161.9 170.4 (105.1) Total net sales $2,873.5 $2,528.1 $2,556.0 AMER. Net sales for fiscal 2018 in the AMER segment increased $52.5 million, or 4.5%, as compared to fiscal 2017. The increase in net sales was primarily due to a $167.1 million increase due to the ramp of new products for existing customers. Partially offsetting the increase were reductions in net sales of $44.1 million due to manufacturing transfers to our APAC segment, $35.4 million due to disengagements with customers, $27.2 million due to end-of-life products, $7.5 million due to program transitions and net decreased customer end-market demand. Net sales for fiscal 2017 in the AMER segment decreased $162.4 million, or 12.2%, as compared to fiscal 2016. The reduction in net sales was driven by overall decreased customer end-market demand as well as decreases of $38.7 million from disengagements with customers, $25.5 million due to manufacturing transfers to our APAC and EMEA segments, $24.0 million due to a customer’s decision to manufacture product internally, $16.4 million from end-of-life products and $5.8 million that resulted from a program disengagement. Partially offsetting these decreases were net sales increases of $36.6 million from the ramp of new programs for existing customers and $11.0 million from the ramp of production for new customers. APAC. Net sales for fiscal 2018 in the APAC segment increased $218.7 million, or 17.1%, as compared to fiscal 2017. The increase in net sales was primarily the result of a $237.2 million increase due to the ramp of new products for existing customers, $44.1 million due to manufacturing transfers from our AMER segment and net increased customer end-market demand. Partially offsetting these increases were reductions in net sales of $70.5 million due to disengagements with customers and $11.5 million due to end-of-life products. Net sales for fiscal 2017 in the APAC segment increased $117.4 million, or 10.1%, as compared to fiscal 2016. The increase in net sales was primarily due to a $115.6 million increase due to the ramp of new programs for existing customers, net increased customer end-market demand and $21.4 million due to manufacturing transfers from our AMER segment. These increases were partially offset by decreases of $50.3 million due to a program disengagement, $38.6 million due to a customer’s partial divestiture of one of its businesses and $14.6 million that resulted from an end-of-life product. EMEA. Net sales for fiscal 2018 in the EMEA segment increased $88.7 million, or 46.0%, as compared to fiscal 2017. The increase in net sales was primarily due to a $77.6 million increase due to the ramp of new products for existing customers and net increased customer end-market demand. Net sales for fiscal 2017 in the EMEA segment increased $22.4 million, or 13.1%, as compared to fiscal 2016. The increase in net sales was primarily attributable to a $34.6 million increase due to the ramp of new programs for existing customers and $4.1 million due to manufacturing transfers from our AMER segment. Partially offsetting the increases were net decreased customer end-market demand and a $3.2 million decrease from end-of-life products. 30 Our net sales by market sector for the indicated fiscal years were as follows (in millions): Market Sector 2018 2017 2016 Healthcare/Life Sciences Industrial/Commercial Communications Aerospace/Defense Total net sales $1,039.9 917.7 470.8 445.1 $ 858.8 788.3 477.7 403.3 $ 780.3 774.2 597.1 404.4 $2,873.5 $2,528.1 $2,556.0 Healthcare/Life Sciences. Net sales for increased $181.1 million, or 21.1%, as compared to fiscal 2017. The increase was primarily driven by increases in net sales of $179.8 million due to the ramp of new products for existing customers, net increased customer end-market demand and $7.6 million from the ramp of production for new customers. Partially offsetting the increases were decreases in net sales of $30.1 million due to end-of-life products. fiscal 2018 in the Healthcare/Life Sciences sector Net sales for fiscal 2017 in the Healthcare/Life Sciences sector increased $78.5 million or 10.1%, as compared to fiscal 2016. The increase was primarily driven by increases in net sales of $74.4 million due to the ramp of new programs for existing customers, net increased customer end-market demand and $7.0 million from the ramp of production for new customers. Partially offsetting the increases were decreases in net sales of $24.8 million due to a customer’s decision to manufacture product internally and $2.1 million due to end-of-life products. Industrial/Commercial. Net sales for fiscal 2018 in the Industrial/Commercial sector increased $129.4 million, or 16.4%, as compared to fiscal 2017. The increase was primarily driven by increases in net sales of $176.5 million due to the ramp of new products for existing customers, net increased customer end-market demand and $9.1 million from the ramp of production for new customers. Partially offsetting the increases were decreases in net sales of $57.6 million related to end-of-life products and $38.4 million due to disengagements with customers. Net sales for fiscal 2017 in the Industrial/Commercial sector increased $14.1 million, or 1.8%, as compared to fiscal 2016. The increase was primarily driven by increases in net sales of $84.8 million due to the ramp of new programs for existing customers. Partially offsetting the increases were decreases in net sales of $38.6 million due to a customer’s partial divestiture of one of its businesses, $17.1 million related to a disengagement with a customer and net decreased customer end-market demand. Communications. Net sales for fiscal 2018 in the Communications sector decreased $6.9 million, or 1.4%, as compared to fiscal 2017. The reduction in net sales was primarily driven by a $64.5 million decrease in net sales due to disengagements with customers, which was partially offset by a $57.9 million increase in net sales due to the ramp of production of new products for existing customers. Net sales for fiscal 2017 in the Communications sector decreased $119.4 million, or 20.0%, as compared to fiscal 2016. The reduction in net sales was primarily driven by a $52.4 million decrease in net sales due to a program disengagement, overall net decreased end-market demand, a $20.3 million decrease that resulted from end-of-life products and a $16.9 million decrease due to disengagements with customers. Partially offsetting the decreases was an $18.9 million increase in net sales due to the ramp of production of new products for existing customers. Aerospace/Defense. Net sales for fiscal 2018 in the Aerospace/Defense sector increased $41.8 million, or 10.4%, as compared to fiscal 2017. The increase was primarily attributable to a $38.2 million increase in net sales that resulted from the ramp of new products for existing customers and net increased customer end-market demand. Net sales for fiscal 2017 in the Aerospace/Defense sector decreased $1.1 million, or 0.3%, as compared to fiscal 2016. The decrease was primarily attributable to a $7.5 million reduction that resulted from end-of-life 31 products, a $6.4 million decrease from a program disengagement and net decreased customer end-market demand. Partially offsetting the decreases were a $10.7 million increase in net sales that resulted from the ramp of production for new customers and a $10.2 million increase due to the ramp of production of new products for existing customers. As a percentage of consolidated net sales, net sales attributable to customers representing 10% or more of consolidated net sales as well as the percentage of net sales attributable to our ten largest customers for the indicated fiscal years were as follows: 2018 2017 2016 12.3% 12.2% 11.1% General Electric Company (“GE”) * 10.4% Micron Technology, Inc. (“Micron”) 10.1% * ARRIS Group, Inc. (“Arris”) Top 10 customers 57.2% 55.5% 58.8% * Net sales attributable to the customer were less than 10.0% of * * consolidated net sales for the period. Cost of sales. Cost of sales for fiscal 2018 increased $343.7 million, or 15.1%, as compared to fiscal 2017. Cost of sales is comprised primarily of material and component costs, labor costs and overhead. In fiscal 2018, 2017 and 2016, approximately 89.0%, 89.0% and 90.0%, respectively, of the total cost of sales was variable in nature and fluctuated with sales volumes. Of these amounts, approximately 88% of these costs in each of fiscal 2018, 2017 and 2016 were related to material and component costs. As compared to fiscal 2017, the percentage increase in cost of sales in fiscal 2018 was slightly greater than the 13.7% increase in net sales primarily due to a negative shift in customer mix and the one-time employee bonus. During the three months ended March 31, 2018, due to our ability to access overseas cash as a result of Tax Reform (as defined below), a $13.5 million one-time bonus was approved and paid to full-time, non-executive employees (“one-time employee bonus”), of which $12.6 million impacted cost of sales. Also contributing to the increase for fiscal 2018 as compared to fiscal 2017 was increased fixed costs primarily to support program ramps. Cost of sales for fiscal 2017 decreased $56.4 million, or 2.4%, as compared to fiscal 2016. As compared to fiscal 2016, the percentage decrease in cost of sales in fiscal 2017 was greater than the 1.10% decrease in net sales primarily due to a positive shift in customer mix, then-ongoing supply chain productivity initiatives and decreased inventory obsolescence expenses, which resulted primarily from $2.9 million of inventory losses sustained from a typhoon that impacted the Company’s manufacturing facilities in Xiamen, China during fiscal 2016 (the “typhoon-related losses”). Gross profit. Gross profit for fiscal 2018 increased $1.7 million, or 0.7%, as compared to fiscal 2017. The primary driver of the increase in gross profit was the net sales increase. Gross margin decreased 110 basis points as compared to fiscal 2017. The decrease in gross margin as compared to fiscal 2017 was primarily driven by the larger percentage increase in cost of sales as compared to the increase in net sales, driven by the factors previously discussed. Gross profit for fiscal 2017 increased $28.5 million, or 12.5%, as compared to fiscal 2016. Gross margin increased 120 basis points as compared to fiscal 2016. The primary driver of the increases in gross profit and gross margin as compared to fiscal 2017 was the larger percentage decrease in cost of sales as compared to the decrease in net sales, driven by the factors previously discussed. Operating income. Operating income for fiscal 2018 decreased $11.6 million as compared to fiscal 2017 primarily as a result of a $13.4 million increase in selling and administrative expenses (“S&A”), partially offset by the $1.7 million increase in gross profit. The increase in S&A in fiscal 2018 primarily resulted from a 32 $5.2 million increase in variable compensation expense and a $2.8 million increase in salary and wage-related expenses. Operating margin decreased to 4.1% in fiscal 2018 from 5.1% in fiscal 2017 primarily due to the decrease in gross margin and increase in S&A expenses, due to the factors discussed above. Operating income for fiscal 2017 increased $30.5 million as compared to fiscal 2016 as a result of the increase in gross profit and a $7.0 million decrease in restructuring costs, partially offset by a $5.1 million increase in S&A. Restructuring costs in fiscal 2016 related to the closure of our manufacturing facility in Fremont, California and the partial closure of our Livingston, Scotland facility. The increase in S&A in fiscal 2017 resulted from a $3.5 million increase in variable compensation expense as a result of improved ROIC and $2.0 million of increased salary and wage-related expenses, partially offset by a $1.9 million decrease in share-based compensation expense. While the level of fiscal 2017 share-based compensation expense benefited from the non-recurrence of $5.2 million of accelerated share-based compensation expense related to the retirement of the Company’s former President and Chief Executive Officer in fiscal 2016, that effect was partially offset by a non-recurring $2.1 million equity grant in 2017 in connection with his appointment as Executive Chairman of the Board. Operating margin increased to 5.1% in fiscal 2017 from 3.9% in fiscal 2016. A discussion of operating income (loss) by reportable segment is presented below (in millions): Operating income (loss): AMER APAC EMEA Corporate and other costs Total operating income 2018 2017 2016 $ 38.6 213.9 1.5 (135.7) $ 41.9 200.1 (6.2) (105.9) $ 64.9 155.5 (3.7) (117.3) $ 118.3 $ 129.9 $ 99.4 AMER. Operating income decreased $3.3 million in fiscal 2018 as compared to fiscal 2017, primarily as a result of increased costs to support new program ramps and a negative shift in customer mix, partially offset by the increase in net sales. Operating income for fiscal 2017 decreased $23.0 million as compared to fiscal 2016, primarily as a result of the decrease in net sales and increased variable labor costs to support new program ramps. The impact of the decrease in net sales was partially offset by a positive shift in customer mix due in part to decreased net sales to lower margin customers that resulted from disengagements with two customers. APAC. Operating income increased $13.8 million in fiscal 2018 as compared to fiscal 2017, primarily as a result of the increase in net sales, partially offset by a negative shift in customer mix and increased costs to support new program ramps. Operating income for fiscal 2017 increased $44.6 million as compared to fiscal 2016, primarily as a result of the increase in net sales, a positive shift in customer mix, supply chain productivity initiatives and decreased inventory obsolescence expenses, which resulted primarily from the $2.9 million of losses sustained in fiscal 2016 from the Xiamen typhoon discussed above. EMEA. Operating income increased $7.7 million in fiscal 2018 as compared to fiscal 2017 primarily due to the increase in net sales, partially offset by increased costs to support new program ramps. Operating loss for fiscal 2017 increased $2.5 million as compared to fiscal 2016 primarily due to increased labor costs to support new program ramps, partially offset by the impact of the increase in net sales. Other expense. Other expense for fiscal 2018 increased $2.6 million as compared to fiscal 2017. The increase in other expense for fiscal 2018 was primarily due to a $2.1 million increase in factoring fees related to our 33 accounts receivable purchase program. Refer to “Liquidity and Capital Resources – Financing Activities” for additional detail on the Company’s accounts receivable purchase program. Other expense for fiscal 2017 decreased $4.0 million as compared to fiscal 2016. The decrease in other expense was primarily due to the impact of foreign exchange volatility, which resulted in a foreign exchange gain of $2.3 million during fiscal 2017 as compared to a $1.7 million loss during fiscal 2016. This was partially offset by $2.2 million of expense related to the Company’s accounts receivable purchase program. Refer to “Liquidity and Capital Resources–Financing Activities” for additional detail on the Company’s accounts receivable purchase program. Income taxes. Income tax expense and effective annual income tax rates for fiscal 2018, 2017 and 2016, as well as information as to the effects of the U.S. Tax Cuts and Jobs Act (“Tax Reform”) in fiscal 2018, were as follows (dollars in millions): Income tax expense, as reported (GAAP) Non-recurring impact of Tax Reform Impact of valuation allowance release Impact of one-time employee bonus Impact of other non-recurring tax items Income tax expense, as adjusted (non-GAAP) (1) Effective tax rate, as reported (GAAP) Non-recurring impact of Tax Reform Impact of valuation allowance release Impact of one-time employee bonus Impact of other non-recurring tax items Effective tax rate, as adjusted (non-GAAP) (1) 2018 $ 94.6 (85.9) 3.6 0.3 (1.1) $ 11.5 2017 $ 9.8 — — — — $ 9.8 2016 $11.0 — — — — $11.0 2018 2017 2016 87.9% (79.8) 3.4 (1.0) (1.0) 9.5% 8.0% — — — — 8.0% 12.6% — — — — 12.6% (1) We believe the non-GAAP presentation of income tax expense and the effective annual tax rate excluding non-recurring tax items, consisting of those related to Tax Reform and the one-time employee bonus, insight over the change from the comparative reporting periods by isolating the provides additional significant, non-recurring impact of Tax Reform. In addition, the Company believes that its income tax expense, as adjusted, and effective tax rate, as adjusted, enhance the ability of investors to analyze the Company’s operating performance and supplement, but do not replace, its income tax expense and effective tax rate calculated in accordance with U.S. GAAP. On December 22, 2017, Tax Reform was enacted and made significant changes to U.S. corporate income tax, including transitioning the U.S. to a dividend exemption system and requiring a deemed dividend on historical undistributed earnings of foreign subsidiaries at a reduced tax rate. Tax Reform also includes provisions that will impact us beginning in fiscal 2019, such as a U.S. tax on certain foreign low-taxed earnings and a limitation placed on the deductibility of domestic interest expense. The $94.6 million of tax expense recorded during fiscal 2018 includes $85.9 million related to the enactment of Tax Reform. The amount recorded due to Tax Reform incorporates regulations issued by the Internal Revenue Service, as well as state tax agencies, and includes the use of current year tax losses and net operating loss carry forwards. Also included in the fiscal 2018 income tax expense is a $3.6 million benefit for the valuation allowance released against the net deferred tax assets in the U.S. as we expect the U.S. to have future taxable income due to the Global Intangible Low-Taxed Income provisions of Tax Reform. We consider the tax expense recorded for Tax Reform to be complete at this time. However, it is possible that additional legislation, 34 regulations and/or guidance may be issued within the provisional reporting period that may result in additional adjustments to the tax expense recorded related to Tax Reform. As a result of Tax Reform, our blended U.S. statutory rate for fiscal 2018 is 24.5%. This results from a statutory tax rate of 35% for the first three months of fiscal 2018, and a statutory tax rate of 21% for the remainder of fiscal 2018. Our annual effective tax rate varies from the U.S. statutory rate primarily due to the geographic distribution of worldwide earnings as well as a tax holiday granted to a subsidiary located in the APAC segment where the Company derives a significant portion of our earnings. In addition, our effective tax rate has been impacted by the changes due to Tax Reform discussed above. Our effective tax rate also may be impacted by disputes with taxing authorities, tax planning activities, adjustments to uncertain tax positions and changes in valuation allowances. The Company has been granted a tax holiday for a foreign subsidiary operating in the APAC segment. This tax holiday will expire on December 31, 2024, and is subject to certain conditions with which the Company expects to continue to comply. In fiscal 2018, 2017 and 2016, the holiday resulted in tax reductions of approximately $39.1 million ($1.19 per basic share, $1.15 per diluted share), $37.5 million ($1.11 per basic share, $1.08 per diluted share), and $27.1 million ($0.81 per basic share, $0.79 per diluted share), respectively. See also Note 6, “Income Taxes,” in Notes to Consolidated Financial Statements for additional information regarding the Company’s tax rate. The annual effective tax rate for fiscal 2019 is expected to be approximately 13.0% to 15.0%. Net Income. Net income for fiscal 2018 decreased $99.1 million, or 88.4%, from fiscal 2017 to $13.0 million. Net income decreased primarily as a result of the $84.8 million increase in income tax expense, which as noted above was substantially due to the impact of Tax Reform, and increases in S&A, as discussed previously. Net income for fiscal 2017 increased $35.7 million, or 46.7%, from fiscal 2016 to $112.1 million. Net income increased primarily as a result of increased gross profit, decreased restructuring costs and decreased foreign exchange losses, partially offset by increases in S&A, as discussed previously. Diluted earnings per share. Diluted earnings per share for fiscal 2018, 2017 and 2016, as well as information as to the effects of non-recurring events that occurred in fiscal 2018 and fiscal 2016, as previously discussed and detailed below, were as follows (dollars in millions): Diluted earnings per share, as reported (GAAP) One-time employee bonus, net of tax Non-recurring impact of Tax Reform Typhoon-related losses, net of tax Accelerated stock-based compensation expense (1) Restructuring costs Diluted earnings per share, as adjusted (non-GAAP) (2) 2018 2017 2016 $0.38 0.39 2.46 — — — $3.23 $3.24 — — — — — $3.24 $2.24 — — 0.06 0.15 0.21 $2.66 (1) During fiscal 2016, $5.2 million of accelerated stock-based compensation expense was recorded in selling and administrative expenses related to a retirement agreement with the Company’s former Chief Executive Officer. (2) We believe the non-GAAP presentation of diluted earnings per share excluding non-recurring tax items, consisting of those related to Tax Reform and the one-time employee bonus, as well as the impacts of the typhoon-related losses, accelerated stock-based compensation expense and restructuring costs, provide additional insight over the change from the comparative reporting periods by eliminating the effects of 35 non-recurring or unusual items. In addition, the Company believes that its diluted earnings per share, as adjusted, enhances the ability of investors to analyze the Company’s operating performance and supplements, but does not replace, its diluted earnings per share calculated in accordance with U.S. GAAP. Diluted earnings per share decreased to $0.38 in fiscal 2018 from $3.24 in fiscal 2017 primarily as a result of decreased net income due to the factors discussed above. Diluted earnings per share increased to $3.24 in fiscal 2017 from $2.24 in fiscal 2016 primarily as a result of increased net income. Return on Invested Capital (“ROIC”) and Economic Return. We use a financial model that is aligned with our business strategy and includes a ROIC goal of 500 basis points over our weighted average cost of capital (“WACC”), which we refer to as “Economic Return,” and a 4.7% to 5.0% operating margin target. Our primary focus is on our Economic Return goal of 5.0%, which is designed to create shareholder value and generate sufficient cash to self-fund our targeted organic revenue growth rate of 12.0%. ROIC and Economic Return are non-GAAP financial measures. Non-GAAP financial measures, including ROIC and Economic Return, are used for internal management goals and decision making because such measures provide management and investors additional insight into financial performance. In particular, we provide ROIC and Economic Return because we believe they offer insight into the metrics that are driving management decisions because we view ROIC and Economic Return as important measures in evaluating the efficiency and effectiveness of our long-term capital requirements. We also use a derivative measure of ROIC as a performance criteria in determining certain elements of compensation, and certain compensation incentives are based on Economic Return performance. We define ROIC as tax-effected operating income before restructuring and other special items divided by average invested capital over a rolling five-quarter period for the fiscal year. Invested capital is defined as equity plus debt, less cash and cash equivalents. Other companies may not define or calculate ROIC in the same way. ROIC and other non-GAAP financial measures should be considered in addition to, not as a substitute for, measures of our financial performance prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). We review our internal calculation of WACC annually. Our WACC was 9.5% for fiscal year 2018, 10.5% for fiscal year 2017, and 11.0% for fiscal year 2016. By exercising discipline to generate ROIC in excess of our WACC, our goal is to create value for our shareholders. ROIC was 16.1%, 16.2%, and 13.8% for fiscal 2018, 2017 and 2016, respectively. Fiscal 2018 ROIC of 16.1% reflects an Economic Return of 6.6%, based on our weighted average cost of capital of 9.5%. For a reconciliation of ROIC, Economic Return and adjusted operating income (tax effected) to our financial statements that were prepared using GAAP, see Exhibit 99.1 to this annual report on Form 10-K, which exhibit is incorporated herein by reference. Refer to the table below, which includes the calculation of ROIC and Economic Return (dollars in millions) for the indicated periods: 2018 2017 2016 Adjusted operating income (tax effected) Average invested capital After-tax ROIC WACC Economic Return 36 $119.5 738.3 $102.0 740.0 $118.6 735.6 16.1% 16.2% 13.8% 9.5% 10.5% 11.0% 2.8% 5.7% 6.6% LIQUIDITY AND CAPITAL RESOURCES Cash and cash equivalents and restricted cash were $297.7 million as of September 29, 2018, as compared to $569.3 million as of September 30, 2017. As of September 29, 2018, 68.6% of our cash balance was held outside of the U.S. by our foreign subsidiaries. With the enactment of Tax Reform, we believe that our offshore cash can be accessed in a more tax efficient manner than before Tax Reform. As previously discussed, we recorded $85.9 million of tax expense during fiscal 2018, which was associated with the deemed repatriation of undistributed foreign earnings and the reversal of our permanently reinvested assertion on foreign earnings in connection with Tax Reform. During fiscal 2018 we repatriated approximately $431.2 million from our APAC region. We repaid $175.0 million in principal amount of our Senior Notes that matured on June 15, 2018 (the “2011 Notes”) with $25.0 million of available cash and proceeds from the issuance of $150.0 million in principal of the 2018 Notes (as defined below). Currently, we believe that our cash balance, together with cash available under our Credit Facility, will be sufficient to meet our liquidity needs, including potential share repurchases, for the next twelve months and for the foreseeable future. Our future cash flows from operating activities will be reduced by $72.5 million due to cash payments for accrued income taxes related to Tax Reform. The table below provides the expected timing of these future cash outflows, excluding $11.5 million of foreign withholding taxes and state taxes on the deemed repatriation of undistributed foreign earnings since the exact timing of the payments is unknown as of September 29, 2018. The remaining $61.0 million represents U.S. federal taxes on the deemed repatriation of undistributed foreign earnings that are payable over an eight year period in accordance with the following installment schedule beginning in fiscal 2019 (in millions): 2019 2020 2021 2022 2023 2024 2025 2026 Total $ 4.9 4.9 4.9 4.9 4.9 9.1 12.2 15.2 $61.0 Cash Flows. The following table provides a summary of cash flows for fiscal 2018, 2017 and 2016, excluding the effect of exchange rates on cash and cash equivalents and restricted cash (in millions): Cash provided by operating activities Cash used in investing activities Cash (used in) provided by financing activities 2018 2017 2016 $ 66.8 $ (74.6) $(265.5) $171.7 $ (37.8) 1.3 $ $127.7 $ (26.5) $ (21.3) Operating Activities. Cash flows provided by operating activities were $66.8 million for fiscal 2018, as compared to $171.7 million for fiscal 2017. The decrease was primarily due to cash flow (reductions) improvements of: • • • $(84.4) million in accounts receivable cash flows, which resulted primarily from the increase in net sales and the initial implementation of a new factoring program during fiscal 2017 $(54.5) million in inventory cash flows driven by increased inventory levels to support the ramp of new customer programs $(39.3) million in customer deposit cash flows driven by significant deposits received from four customers in fiscal 2017 that were utilized or returned during fiscal 2018 37 • • $(13.5) million due to the payment of the one-time employee bonus; and $86.4 million in accounts payables cash flows driven by increased purchasing activity to support increased net sales. Cash flows provided by operating activities were $171.7 million for fiscal 2017, as compared to cash flows provided by operating activities of $127.7 million for fiscal 2016. The improvement was primarily due to the increase in net income and a $13.9 million change in working capital, as discussed below. Working capital cash flows in fiscal 2017 improved as compared to fiscal 2016 primarily due to working capital cash flow improvements and (reductions) of: • • • • $90.7 million in accounts receivable cash flows, which resulted primarily from increased factoring activity $18.1 million in customer deposit cash flows driven by significant deposits received from two customers $(85.3) million in inventory cash flows driven by increased inventory levels to support the ramp of new customer programs; and $(11.7) million in other current and noncurrent assets cash flows resulting from increases in prepaid arrangements. The following table provides a summary of cash cycle days for the periods indicated (in days): Days in accounts receivable Days in inventory Days in accounts payable Days in cash deposits Annualized cash cycle Three months ended September 29, 2018 September 30, 2017 October 1, 2016 47 104 (66) (12) 73 50 99 (63) (16) 70 58 87 (61) (13) 71 We calculate days in accounts receivable as accounts receivable for the respective quarter divided by annualized sales for the respective quarter by day. We calculate days in inventory, accounts payable, and cash deposits as each balance sheet line item for the respective quarter divided by annualized cost of sales for the respective quarter by day. We calculate annualized cash cycle as the sum of days in accounts receivable and days in inventory, less days in accounts payable and days in cash deposits. As of September 29, 2018, annualized cash cycle days increased three days compared to September 30, 2017 due to the following factors: Days in accounts receivable for the three months ended September 29, 2018 decreased three days compared to the three months ended September 30, 2017. The decrease is primarily attributable to an $82.0 million increase in accounts receivable sold under factoring programs during the fourth quarter of fiscal 2018 as compared to the fourth quarter of fiscal 2017, which was partially offset by the increase in net sales and unfavorable changes to payment terms with certain customers. Days in inventory for the three months ended September 29, 2018 increased five days compared to the three months ended September 30, 2017. The increase is primarily driven by an increase in inventory levels as a result of experiencing longer lead times for certain components for new programs and to support new program ramps. In order to maintain a high level of customer service, we are procuring components earlier, which has led to the increase in inventory. 38 Days in accounts payable for the three months ended September 29, 2018 increased three days compared to the three months ended September 30, 2017. The increase is primarily driven by increased purchasing activity to support higher revenue levels. Days in cash deposits for the three months ended September 29, 2018 decreased four days compared to the three months ended September 30, 2017. The decrease was primarily attributable to significant deposits received from several customers in fiscal 2017 that were utilized or returned during fiscal 2018. Free Cash Flow. We define free cash flow (“FCF”), a non-GAAP financial measure, as cash flow provided by operations less capital expenditures. FCF was $4.0 million for fiscal 2018 compared to $133.2 million for fiscal 2017, a decrease of $129.2 million. Non-GAAP financial measures, including FCF, are used for internal management assessments because such measures provide additional insight to investors into ongoing financial performance. In particular, we provide FCF because we believe it offers insight into the metrics that are driving management decisions. We view FCF as an important financial metric as it demonstrates our ability to generate cash and can allow us to pursue opportunities that enhance shareholder value. FCF is a non-GAAP financial measure that should be considered in addition to, not as a substitute for, measures of our financial performance prepared in accordance with GAAP. A reconciliation of FCF to our financial statements that were prepared using GAAP follows (in millions): Cash flows provided by operating activities Payments for property, plant and equipment Free cash flow 2018 2017 2016 $ 66.8 (62.8) $171.7 (38.5) $127.7 (31.1) $ 4.0 $133.2 $ 96.6 Investing Activities. Cash flows used in investing activities were $74.6 million for fiscal 2018 compared to $37.8 million for fiscal 2017. The increase in cash used in investing activities was due to a $24.3 million increase in capital expenditures primarily to fund the purchase of an additional manufacturing facility in Penang, Malaysia and to support new capabilities, new program ramps, and to replace or refresh older equipment. There was an additional $12.4 million increase in cash flows used in investing activities for the acquisition of the assets of one of the business lines of Cascade Controls, Inc.; see Note 15, “Acquisition,” in Notes to Consolidated Financial Statements for further detail. Cash flows used in investing activities were $37.8 million for fiscal 2017 compared to $26.5 million for fiscal 2016. The increase in cash used in investing activities was due to a $7.4 million increase in capital expenditures primarily to support new capabilities, new program ramps, and to replace or refresh older equipment, and a $3.9 million decrease in proceeds received from the sale of property, plant and equipment, primarily related to the sale of our former engineering facility in Neenah, Wisconsin in fiscal 2016. We utilized available cash and operating cash flows as the sources for funding our operating requirements during fiscal 2018. We currently estimate capital expenditures for fiscal 2019 will be approximately $70.0 million to $90.0 million. Financing Activities. Cash flows used in financing activities were $265.5 million for fiscal 2018 compared to cash flows provided by financing activities of $1.3 million for fiscal 2017. The increase was primarily attributable to a $141.0 million increase in pay-downs on our revolving credit facility, a $102.9 million increase in cash used to repurchase our common stock and a $25.0 million reduction in the balance of outstanding senior notes as a result of refinancing the notes, as discussed further below. Cash flows provided by financing activities were $1.3 million for fiscal 2017 compared to cash flows used in financing activities of $21.3 million for fiscal 2016. The increase was primarily attributable to a net $32.8 million 39 increase in borrowings, which was partially offset by a $4.1 million increase in cash used to repurchase our shares under the stock repurchase program described below, a $3.5 million increase in payments related to tax withholding for share-based compensation and a $3.0 million decrease in proceeds received from stock option exercises. On February 14, 2018, the Board of Directors approved a new stock repurchase plan under which the Company is authorized to repurchase $200.0 million of its common stock (the “2018 Program”). The 2018 Program commenced upon completion of the 2016 Program, as defined below. During fiscal 2018, the Company repurchased 343,642 shares under the 2018 Program for $21.2 million, at an average price of $61.61 per share. As of September 29, 2018, $178.8 million of authority remained under the 2018 Program. On June 6, 2016, the Board of Directors authorized a multi-year stock repurchase program under which the Company was authorized to repurchase up to $150.0 million of its common stock beginning in fiscal 2017 (the “2016 Program”). During fiscal 2018 and 2017, the Company completed the 2016 Program by repurchasing 1,914,596 and 655,470 shares for $115.9 million and $34.1 million, at an average price of $60.52 and $52.08 per share, respectively. On August 20, 2015, the Board of Directors authorized a stock repurchase program under which the Company was authorized to repurchase up to $30.0 million of its common stock during fiscal 2016. During fiscal 2016, the Company repurchased 760,903 shares for $30.0 million, at an average price of $39.43 per share. All shares repurchased under the aforementioned programs were recorded as treasury stock. On June 15, 2018, the Company entered into a Note Purchase Agreement (the “2018 NPA”) pursuant to which it issued an aggregate of $150.0 million in principal amount of unsecured senior notes, consisting of $100.0 million in principal amount of 4.05% Series A Senior Notes, due on June 15, 2025, and $50.0 million in principal amount of 4.22% Series B Senior Notes, due on June 15, 2028 (collectively, the “2018 Notes”), in a private placement. The 2018 NPA includes customary operational and financial covenants with which the Company is required to comply, including, among others, maintenance of certain financial ratios such as a total leverage ratio and a minimum interest coverage ratio. The 2018 Notes may be prepaid in whole or in part at any time, subject to payment of a make-whole amount; interest on the 2018 Notes is payable semiannually. As of September 29, 2018, the Company was in compliance with the covenants under the 2018 NPA. In connection with the issuance of the 2018 Notes, on June 15, 2018, the Company repaid, on maturity $175.0 million in principal amount of its 5.20% Senior Notes (the “2011 Notes”). The Company’s Credit Facility has a $300.0 million maximum commitment that expires on July 5, 2021. The Credit Facility may be further increased to $500.0 million, generally by mutual agreement of the Company and the lenders, subject to certain customary conditions. For further information regarding the Credit Facility, see Note 4, “Debt, Capital Lease Obligations and Other Financing” in Notes to Consolidated Financial Statements. The financial covenants (as defined under the Credit Agreement) require, among other covenants, that the Company maintain, as of each fiscal quarter end, a maximum total leverage ratio and a minimum interest coverage ratio. As of September 29, 2018, the Company was in compliance with all financial covenants of the Credit Agreement. The Credit Agreement and the 2018 NPA allow for the future payment of cash dividends or the repurchase of shares provided that no event of default (including any failure to comply with a financial covenant) exists at the time of, or would be caused by, the dividend payment or the share repurchases. We have not paid cash dividends in the past and do not currently anticipate paying them in the future. However, we evaluate from time to time potential uses of excess cash, which in the future may include share repurchases above those already authorized, a special dividend or recurring dividends. 40 The Company has Master Accounts Receivable Purchase Agreements with MUFG Bank, New York Branch, formerly known as The Bank of Tokyo-Mitsubishi UFJ, Ltd. (the “MUFG RPA”), and HSBC Bank (China) Company Limited, Xiamen branch (the “HSBC RPA”), under which the Company may elect to sell receivables, at a discount, on an ongoing basis. The MUFG RPA was amended on September 19, 2018 to increase the maximum facility amount from $210.0 million to $230.0 million. The maximum facility amount under the HSBC RPA as of September 29, 2018 is $60.0 million. The MUFG RPA is subject to expiration on October 3, 2019, but will be automatically extended each year unless any party gives no less than 10 days prior notice that the agreement should not be extended. The terms of the HSBC RPA are generally consistent with the terms of the MUFG RPA discussed above. The Company previously sold receivables under a former trade accounts receivable sale program that expired during the first fiscal quarter of 2017. The Company sold $712.9 million, $418.0 million and $65.6 million of trade accounts receivable under these programs during fiscal years 2018, 2017 and 2016, respectively, in exchange for cash proceeds of $708.6 million, $415.8 million and $65.0 million, respectively. In all cases, the sale discount was recorded within “Miscellaneous expense” in the Consolidated Statements of Comprehensive Income in the period of the sale. For further information regarding the receivable sale programs, see Note 14, “Trade Accounts Receivable Sale Programs,” in Notes to Consolidated Financial Statements. Based on current expectations, we believe that our projected cash flows provided by operations, available cash and cash equivalents, potential borrowings under the Credit Facility and our leasing capabilities should be sufficient to meet our working capital and fixed capital requirements for the next twelve months. If our future financing needs increase, we may need to arrange additional debt or equity financing. Accordingly, we evaluate and consider from time to time various financing alternatives to supplement our financial resources. However, we cannot be assured that we will be able to make any such arrangements on acceptable terms. 41 CONTRACTUAL OBLIGATIONS, COMMITMENTS AND OFF-BALANCE SHEET OBLIGATIONS Our disclosures regarding contractual obligations and commercial commitments are located in various parts of our regulatory filings. Information in the following table provides a summary of our contractual obligations and commercial commitments as of September 29, 2018 (dollars in millions): Payments Due by Fiscal Year Contractual Obligations Total 2019 2020-2021 2022-2023 Debt Obligations (1) Capital Lease Obligations (2) Operating Lease Obligations Purchase Obligations (3) Repatriation Tax on Undistributed Foreign Earnings (4) Other Liabilities on the Balance Sheet (5) Other Liabilities not on the Balance Sheet (6) Other Financing Obligations (7) $ 199.5 46.0 38.6 769.3 61.0 13.1 6.1 121.3 $ 6.2 6.6 9.5 742.7 4.9 1.3 1.0 3.3 Total Contractual Cash Obligations $1,254.9 $775.5 $12.4 6.0 14.2 25.5 9.8 2.5 0.8 8.7 $79.9 $12.2 3.2 7.2 0.8 9.7 2.4 — 9.1 $44.6 2024 and thereafter $168.7 30.2 7.7 0.3 36.6 6.9 4.3 100.2 $354.9 1) Includes $150.0 million in principal amount of 2018 Notes as well as interest; see Note 4, “Debt, Capital Lease Obligations and Other Financing,” in Notes to Consolidated Financial Statements for further information. 2) As of September 29, 2018, capital lease obligations consists of capital lease payments and interest as well as the non-cash financing obligation related to the failed sale-leasebacks in Guadalajara, Mexico; see Note 4, “Debt, Capital Lease Obligations and Other Financing,” in Notes to Consolidated Financial Statements for further information. 3) As of September 29, 2018, purchase obligations consist primarily of purchases of inventory and equipment in the ordinary course of business. 4) Consists of U.S. federal income taxes on the deemed repatriation of undistributed foreign earnings due to Tax Reform.

The Company cannot make reliable estimates of the future cash flows by period related to these obligations. 6) As of September 29, 2018, other obligations not on the balance sheet consist of guarantees and a commitment for salary continuation and certain benefits in the event employment of one executive officer of the Company is terminated without cause. Excluded from the amounts disclosed are certain bonus and incentive compensation amounts, which would be paid on a prorated basis in the year of termination. 7) Includes future minimum lease payments for two facilities in Guadalajara, Mexico, leased under 10-year and 15-year base lease agreements, both of which include two 5-year renewal options; see Note 4, “Debt, Capital Lease Obligations and Other Financing,” in Notes to Consolidated Financial Statements for further information. 42 DISCLOSURE ABOUT CRITICAL ACCOUNTING ESTIMATES Our accounting policies are disclosed in Note 1 of Notes to Consolidated Financial Statements. During fiscal 2018, there were no material changes to these policies. Our more critical accounting estimates are described below: Revenue Recognition: Net sales from manufacturing services are recognized when the product has been shipped, the risk of ownership has transferred to the customer, the price to the buyer is fixed or determinable, and terms and generally occurs upon recoverability is reasonably assured. This point depends on contractual shipment of the goods from Plexus. Generally, there are no formal customer acceptance requirements or further obligations related to manufacturing services; if such requirements or obligations exist, then a sale is recognized at the time when such requirements are completed and such obligations are fulfilled. Net sales also include amounts billed to customers for shipping and handling. The corresponding shipping and handling costs are included in cost of sales. Net sales from engineering design and development services, which are generally performed under contracts with a duration of twelve months or less, are typically recognized as program costs are incurred by utilizing the proportional performance model. The completed performance model is used if certain customer acceptance criteria exist. Any losses are recognized when anticipated. Income Taxes: Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The Company maintains valuation allowances when it is more likely than not that all or a portion of a deferred tax asset will not be realized. In determining whether a valuation allowance is required, the Company takes into account such factors as prior earnings history, expected future earnings, carryback and carryforward periods, and tax strategies that could potentially enhance the likelihood of the realization of a deferred tax asset. Share-Based Compensation: Generally accepted accounting principles require all grants of share-based compensation to employees to be measured at fair value and expensed in the Consolidated Statements of Comprehensive Income over the service period (generally the vesting period) of the grant. We use the Black- Scholes valuation model to value stock options and the Monte Carlo valuation model to value performance stock units with market conditions. Inventories: Inventories are valued at the lower of cost or market. Cost is determined by the first-in, first-out (“FIFO”) method. Valuing inventories at the lower of cost or market requires the use of estimates and judgment. Customers may cancel their orders, change production quantities or delay production for a number of reasons that are beyond the Company’s control. Any of these, or certain additional actions, could impact the valuation of inventory. Any actions taken by the Company’s customers that could impact the value of its inventory are considered when determining the lower of cost or market valuations. Impairment of Long-Lived Assets: Long-lived assets, including property, plant and equipment and intangible assets with finite lives are reviewed for impairment and written down to fair value when facts and circumstances indicate that the carrying value of long-lived assets or asset groups may not be recoverable through estimated future undiscounted cash flows. If an impairment has occurred, a write-down to estimated fair value is made and the impairment loss is recognized as a charge against current operations. The impairment analysis is based on management’s assumptions, including future revenue and cash flow projections. Circumstances that may lead to impairment of property, plant and equipment and intangible assets with finite lives include reduced expectations for future performance or industry demand and possible further restructurings, among others. 43 Allowance for Doubtful Accounts: Accounts receivable are reflected at net realizable value based on anticipated losses due to potentially uncollectible balances. Anticipated losses are based on management’s analysis of historical losses and changes in customers’ credit status. Warranties: The Company provides for an estimate of costs that may be incurred under its limited warranty at the time product revenue is recognized and establishes additional reserves for specifically identified product issues. These costs primarily include labor and materials, as necessary, associated with repair or replacement and are included in the Company’s accompanying Consolidated Balance Sheets in “other current accrued liabilities.” The primary factors that affect the Company’s warranty liability include the value and the number of shipped units and historical and anticipated rates of warranty claims. As these factors are impacted by actual experience and future expectations, the Company assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK We are exposed to market risk from changes in foreign exchange and interest rates. We selectively use financial instruments to reduce such risks. We do not use derivative financial instruments for speculative purposes. Foreign Currency Risk Our international operations create potential foreign exchange risk. Our policy is to selectively hedge our foreign currency denominated transactions in a manner that partially offsets the effects of changes in foreign currency exchange rates. We typically use foreign currency contracts to hedge only those currency exposures associated with certain assets and liabilities denominated in non-functional currencies. Corresponding gains and losses on the underlying transaction generally offset the gains and losses on these foreign currency hedges. Our percentages of transactions denominated in currencies other than the U.S. dollar for the indicated fiscal years were as follows: Net Sales Total Costs 2018 2017 2016 10% 15% 9% 14% 8% 13% The Company has evaluated the potential foreign currency exchange rate risk on transactions denominated in currencies other than the U.S. dollar for the periods presented above. Based on the Company’s overall currency exposure, as of September 29, 2018, a 10.0% change in the value of the U.S. dollar relative to our other transactional currencies would not have a material effect on the Company’s financial position, results of operations, or cash flows. Interest Rate Risk We have financial instruments, including cash equivalents and debt, which are sensitive to changes in interest rates. The primary objective of our investment activities is to preserve principal, while maximizing yields without significantly increasing market risk. To achieve this, we maintain our portfolio of cash equivalents in a variety of highly rated securities, money market funds and certificates of deposit, and limit the amount of principal exposure to any one issuer. 45 ITEM 8.

We also have audited the Company’s internal control over financial reporting as of September 29, 2018, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of September 29, 2018 and September 30, 2017, and the results of its operations and its cash flows for each of the three years in the period ended September 29, 2018 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of September 29, 2018, based on criteria established in Internal Control – Integrated Framework (2013) issued by the COSO. Basis for Opinions The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Annual Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. 47 Definition and Limitations of Internal Control over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. limitations, /s/ PricewaterhouseCoopers LLP Milwaukee, Wisconsin November 16, 2018 We have served as the Company’s auditor since at least 1985.

Plexus is headquartered in Neenah, Wisconsin and has operations in the Americas (“AMER”), Europe, Middle East, and Africa (“EMEA”) and Asia-Pacific (“APAC”) regions. Significant Accounting Policies Consolidation Principles and Basis of Presentation: The consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and include the accounts of Plexus Corp. and its subsidiaries. All intercompany transactions have been eliminated. Certain prior period amounts have been reclassified to conform to the current period presentation. The Company’s fiscal year ends on the Saturday closest to September 30. The Company also uses a “4-4-5” weekly accounting system for the interim periods in each quarter. Each quarter, therefore, ends on a Saturday at the end of the 4-4-5 period. Periodically, an additional week must be added to the fiscal year to re-align with the Saturday closest to September 30. Fiscal 2018, fiscal 2017 and fiscal 2016 each included 52 weeks. Cash and Cash Equivalents and Restricted Cash: Cash equivalents include short-term highly liquid investments and are classified as Level 1 in the fair value hierarchy described below. Restricted cash represents cash received from customers to settle invoices sold under accounts receivable purchase agreements that is contractually required to be set aside. The restrictions will lapse when the cash is remitted to the purchaser of the receivables. Restricted cash is also classified as Level 1 in the fair value hierarchy described below. As of September 29, 2018 and September 30, 2017, cash and cash equivalents and restricted cash consisted of the following (in thousands): Cash Money market funds and other Restricted cash 2018 2017 $ 99,197 198,072 417 $264,222 304,638 394 Total cash and cash equivalents and restricted cash $297,686 $569,254 Inventories: Inventories are valued at the lower of cost or market. Cost is determined by the first-in, first-out (“FIFO”) method. Valuing inventories at the lower of cost or market requires the use of estimates and judgment. Customers may cancel their orders, change production quantities or delay production for a number of reasons that are beyond the Company’s control. Any of these, or certain additional actions, could impact the valuation of inventory. Any actions taken by the Company’s customers that could impact the value of its inventory are considered when determining the lower of cost or market valuations. In certain instances, in accordance with contractual terms, the Company receives customer deposits to offset obsolete and excess inventory risks. 53 Plexus Corp. Notes to Consolidated Financial Statements Property, Plant and Equipment and Depreciation: Property, plant and equipment is stated at cost and depreciated using the straight-line method over the estimated useful lives of the respective assets. Estimated useful lives for major classes of depreciable assets are as follows: Buildings and improvements Machinery and equipment Computer hardware and software 5-39 years 3-7 years 3-10 years Certain facilities and equipment held under capital leases are classified as property, plant and equipment and amortized using the straight-line method over the term of the lease and the related obligations are recorded as liabilities. Amortization of assets held under capital leases is included in depreciation expense (see Note 3, “Property, Plant and Equipment”) and the financing component of the lease payments is classified as interest expense. Maintenance and repairs are expensed as incurred. The Company capitalizes significant costs incurred in the acquisition or development of software for internal use. This includes costs of the software, consulting services and compensation costs for employees directly involved in developing internal use computer software. Impairment of Long-Lived Assets: Long-lived assets, including property, plant and equipment and intangible assets with finite lives are reviewed for impairment and written down to fair value when facts and circumstances indicate that the carrying value of long-lived assets or asset groups may not be recoverable through estimated future undiscounted cash flows. If an impairment has occurred, a write-down to estimated fair value is made and the impairment loss is recognized as a charge against current operations. The impairment analysis is based on management’s assumptions, including future revenue and cash flow projections. Circumstances that may lead to impairment of property, plant and equipment and intangible assets with finite lives include reduced expectations for future performance or industry demand and possible further restructurings, among others. Revenue Recognition: Net sales from manufacturing services are recognized when the product has been shipped, the risk of ownership has transferred to the customer, the price to the buyer is fixed or determinable, and recoverability is reasonably assured. This point depends on contractual terms and generally occurs upon shipment of the goods from Plexus. Generally, there are no formal customer acceptance requirements or further obligations related to manufacturing services; if such requirements or obligations exist, then a sale is recognized at the time when such requirements are completed and such obligations are fulfilled. Net sales also include amounts billed to customers for shipping and handling. The corresponding shipping and handling costs are included in cost of sales. Net sales from engineering design and development services, which are generally performed under contracts with a duration of twelve months or less, are typically recognized as program costs are incurred by utilizing the proportional performance model. The completed performance model is used if certain customer acceptance criteria exist. Any losses are recognized when anticipated. Net sales from engineering design and development services were less than 5.0% of consolidated net sales for each of fiscal 2018, 2017 and 2016. Income Taxes: Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The Company maintains valuation allowances when it is more likely than not that all or a portion of a deferred tax asset will not be realized. In determining whether a valuation allowance is required, the Company takes into account such factors as prior earnings history, expected future earnings, carryback and carryforward periods, and tax strategies that could potentially enhance the likelihood of the realization of a deferred tax asset. 54 Plexus Corp. Notes to Consolidated Financial Statements Foreign Currency Translation & Transactions: The Company translates assets and liabilities of subsidiaries operating outside of the U.S. with a functional currency other than the U.S. dollar into U.S. dollars using exchange rates in effect at the relevant balance sheet date and net sales, expenses and cash flows at the average exchange rates during the respective periods. Adjustments resulting from translation of the financial statements are recorded as a component of “Accumulated other comprehensive loss.” Exchange gains and losses arising from transactions denominated in a currency other than the functional currency of the entity involved and remeasurement adjustments for foreign operations where the U.S. dollar is the functional currency are included in the Consolidated Statements of Comprehensive Income as a component of “Miscellaneous income (expense).” Exchange gains (losses) on foreign currency transactions were $1.2 million, $2.3 million and $(1.7) million for fiscal 2018, 2017 and 2016, respectively. These amounts include the amount of gain (loss) recognized in income during each fiscal year due to forward currency exchange contracts entered into to hedge recognized assets or liabilities (“non-designated hedges”) the Company entered into during each respective year. Refer to Note 5, “Derivatives and Fair Value Measurements,” for further details on derivatives. Derivatives: All derivatives are recognized on the balance sheets at fair value. The Company periodically enters into forward currency exchange contracts and interest rate swaps. On the date a derivative contract is entered into, the Company designates the derivative as a non-designated hedge or a hedge of a forecasted transaction or of the variability of cash flows to be received or paid related to a recognized asset or liability (a “cash flow” hedge). The Company does not enter into derivatives for speculative purposes. Changes in the fair value of non-designated derivatives are recorded in earnings as are the gains or losses related to the hedged asset or liability. Changes in the fair value of a derivative that qualifies as a cash flow hedge are recorded in “Accumulated other comprehensive loss” within shareholders’ equity, until earnings are affected by the variability of cash flows. Certain forward currency exchange contracts are treated as cash flow hedges and, therefore, $(3.9) million, $2.4 million and $9.0 million was recorded in “Accumulated other comprehensive loss” for fiscal 2018, 2017 and 2016, respectively. See Note 5, “Derivatives and Fair Value Measurements,” for further information. Grants from Government Authorities: Grants from governments are recognized at their fair value where there is reasonable assurance that the grant funds will be received and the Company will comply with all attached conditions to the grant. Government grants relating to property, plant and equipment are recorded as an offset to the carrying value of the related assets at the time of capitalization. Government grants relating to other costs incurred are recognized as an offset to those related costs, for which the grants are intended to compensate for, at the time they are recognized. Earnings Per Share: The computation of basic earnings per common share is based upon the weighted average number of common shares outstanding and net income. The computation of diluted earnings per common share reflects additional dilution from share-based awards, excluding any with an antidilutive effect. See Note 7, “Earnings Per Share,” for further information. Share-based Compensation: The Company measures all grants of share-based payments to employees, including grants of employee stock options, at fair value and expenses them in the Consolidated Statements of Comprehensive Income over the service period (generally the vesting period) of the grant. See Note 9, “Benefit Plans,” for further information. Comprehensive Income (Loss): The Company follows the established standards for reporting comprehensive income (loss), which is defined as the changes in equity of an enterprise except those resulting from shareholder transactions. 55 Plexus Corp. Notes to Consolidated Financial Statements Accumulated other comprehensive loss consists of the following as of September 29, 2018 and September 30, 2017 (in thousands): Foreign currency translation adjustments Cumulative change in fair value of derivative instruments Accumulated other comprehensive loss 2018 2017 $(10,540) (1,439) $(7,482) 2,503 $(11,979) $(4,979) Refer to Note 5, “Derivatives and Fair Value Measurements,” for further explanation regarding the change in fair value of derivative instruments that is recorded to “Accumulated other comprehensive loss.” Use of Estimates: The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. restricted cash, accounts receivable, certain deferred compensation assets held under Fair Value of Financial Instruments: The Company holds financial instruments consisting of cash and cash equivalents, trust arrangements, accounts payable, debt, derivatives, and capital lease obligations. The carrying values of cash and cash equivalents, restricted cash, accounts receivable, and accounts payable as reported in the consolidated financial statements approximate fair value. Derivatives and certain deferred compensation assets held under trust arrangements are recorded at fair value. Accounts receivable are reflected at net realizable value based on anticipated losses due to potentially uncollectible balances. Anticipated losses are based on management’s analysis of historical losses and changes in customers’ credit status. The fair value of the Company’s debt was $151.9 million and $284.5 million as of September 29, 2018 and September 30, 2017, respectively. The carrying value of the Company’s debt was $150.0 million and $283.0 million as of September 29, 2018 and September 30, 2017, respectively. The Company uses quoted market prices when available or discounted cash flows to calculate fair value. If measured at fair value in the financial statements, long-term debt (including the current portion) would be classified as Level 2 in the fair value hierarchy described below. The fair values of the Company’s derivatives are disclosed in Note 5, “Derivatives and Fair Value Measurements.” The fair values of the deferred compensation assets held under trust arrangements are discussed in Note 9, “Benefit Plans.” Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (or exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The accounting guidance establishes a fair value hierarchy based on three levels of inputs that may be used to measure fair value. The input levels are: Level 1: Quoted (observable) market prices in active markets for identical assets or liabilities. Level 2: Inputs other than Level 1 that are observable, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability. Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the asset or liability. Business and Credit Concentrations: Financial the Company to trade accounts receivable and derivative concentrations of credit risk consist of cash, cash equivalents, instruments, specifically related to counterparties. In accordance with the Company’s investment policy, the Company’s cash, cash equivalents and derivative instruments were placed with recognized financial institutions. that potentially subject instruments 56 Plexus Corp. Notes to Consolidated Financial Statements The Company’s investment policy limits the amount of credit exposure in any one issue and the maturity date of the investment securities that typically comprise investment grade short-term debt instruments. Concentrations of credit risk in accounts receivable resulting from sales to major customers are discussed in Note 11, “Reportable Segments, Geographic Information and Major Customers”. The Company, at times, requires cash deposits for services performed. The Company also closely monitors extensions of credit. Recently Issued Accounting Pronouncements Not Yet Adopted: In August 2017, the Financial Accounting Standards Board (“FASB”) issued ASU 2017-12 related to the accounting for hedging activities. The pronouncement expands and refines hedge accounting, aligns the recognition and presentation of the effects of hedging instruments and hedge items in the financial statements, and includes certain targeted improvements to ease the application of current guidance related to the assessment of hedge effectiveness. This guidance is effective for the Company beginning in the first quarter of fiscal year 2020 and early adoption is permitted. The Company is finalizing its assessment of the impact of the guidance, but does not believe it will have a material impact on the Company’s Consolidated Financial Statements. In October 2016, the FASB issued ASU 2016-16 related to the income tax consequences of intra-entity transfers of assets other than inventory. The new standard eliminates the exception for an intra-entity transfer of an asset other than inventory and requires an entity to recognize the income tax consequences when the transfer occurs. This guidance is effective for the Company beginning in the first quarter of fiscal year 2019 and early adoption is permitted. This guidance should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The Company is currently assessing the impact this new standard may have on its Consolidated Financial Statements. In August 2016, the FASB issued ASU 2016-15 related to the classification of certain cash receipts and cash payments, which clarifies how entities should classify certain cash receipts and cash payments on the statement of cash flows. The new standard addresses certain issues where diversity in practice was identified. It also amends existing guidance, which is principles based and often requires judgment to determine the appropriate classification of cash flows as operating, investing or financing activities and clarifies how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. This guidance is effective for the Company beginning in the first quarter of fiscal year 2019. The Company is finalizing its assessment of the impact of the guidance, but does not believe it will have a material impact on the Company’s Consolidated Financial Statements. In February 2016, the FASB issued ASU 2016-02, which requires lessees to recognize most leases on their balance sheets but record expenses on their income statements in a manner similar to current accounting. For lessors, the guidance modifies the classification criteria and the accounting for sales-type and direct financing leases. The guidance is effective for the Company beginning in the first quarter of fiscal year 2020. Early adoption is permitted. The Company is currently in the process of assessing the impact of the adoption of the new standard on its Consolidated Financial Statements and the timing of adoption. In May 2014, the FASB issued ASU 2014-09, which requires an entity to recognize revenue relating to contracts with customers that depicts the transfer of promised goods or services to customers in an amount reflecting the consideration to which the entity expects to be entitled in exchange for such goods or services (“Topic 606”). Topic 606 also requires disclosures enabling users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers and is effective for the Company beginning in the first quarter of fiscal year 2019. The Company developed a comprehensive project plan that team of representatives to conduct an assessment of Topic 606 and its potential impacts on the Company. The project included a global cross-functional 57 Plexus Corp. Notes to Consolidated Financial Statements plan included analyzing the standard’s impact on the Company’s various revenue streams, comparing its historical accounting policies and practices to the requirements of the new standard, and identifying potential differences from applying the requirements of the new standard to its contracts. The Company is in the process of implementing appropriate changes to its current accounting policies, business processes, systems and controls to support revenue recognition and disclosures under Topic 606. The Company has determined that the new standard will result in a change to the timing of revenue recognition for a significant portion of the Company’s revenue, whereby revenue will be recognized “over time,” as products are produced, as opposed to at a “point in time” upon physical delivery. Upon adopting the standard, revenue will be recognized over time for arrangements with customers for which: (i) the Company’s performance does not create an asset with an alternative use to the Company, and (ii) the Company has an enforceable right to payment for performance completed to date. Over time, revenue will be estimated using a cost-based input measurement of progress, under which the extent of progress towards completion will be measured based on the costs incurred during the manufacturing process or as services are rendered as of each period end. If either of the two conditions are not met, revenue will be recognized following the transfer of control of such products to the customer, which typically occurs upon shipment or delivery depending on the terms of the underlying arrangement. The new standard is expected to have a material impact on the Company’s Consolidated Financial Statements upon initial adoption, primarily as the Company recognizes an increase in contract assets for unbilled receivables with a corresponding reduction in finished goods and work-in-process inventory. The Company is adopting Topic 606 at the beginning of fiscal year 2019 using the modified retrospective approach. Upon adoption of the standard, the Company estimates an adjustment to its beginning Retained Earnings balance in the range of $5.0 million to $15.0 million as of September 29, 2018. In addition, the Company estimates reductions to finished goods and work-in-progress inventories in the range of $45.0 million to $70.0 million in aggregate. The Company estimates a corresponding increase to Unbilled Receivables of approximately $55.0 million to $80.0 million. While the Company is substantially complete with the process of quantifying the impacts that will result from applying the new guidance, its assessment will be finalized during the first quarter of fiscal year 2019. The Company has substantially completed the implementation of changes to its processes, policies and internal controls to comply with the new standard and disclosure requirements. The Company believes that no other recently issued accounting standards will have a material impact on its Consolidated Financial Statements, or apply to its operations. 2.

Debt, Capital Lease Obligations and Other Financing Debt and capital lease obligations as of September 29, 2018 and September 30, 2017, consisted of the following (in thousands): 4.05% Senior Notes, due June 15, 2025 4.22% Senior Notes, due June 15, 2028 5.20% Senior Notes, due June 15, 2018 Borrowings under the credit facility Capital lease and other financing obligations Unamortized deferred financing fees Total obligations Less: current portion 2018 2017 $100,000 50,000 — — 39,857 (1,240) 188,617 (5,532) $ — — 175,000 108,000 30,901 (794) 313,107 (286,934) Long-term debt and capital lease obligations, net of current portion $183,085 $ 26,173 On June 15, 2018, the Company entered into a Note Purchase Agreement (the “2018 NPA”) pursuant to which it issued an aggregate of $150.0 million in principal amount of unsecured senior notes, consisting of $100.0 million in principal amount of 4.05% Series A Senior Notes, due on June 15, 2025, and $50.0 million in principal amount of 4.22% Series B Senior Notes, due on June 15, 2028 (collectively, the “2018 Notes”), in a private placement. The 2018 NPA includes customary operational and financial covenants with which the Company is required to comply, including, among others, maintenance of certain financial ratios such as a total leverage ratio and a minimum interest coverage ratio. Such covenants are generally similar to those in the Note Purchase Agreement related to the 2011 Notes (as defined below). The 2018 Notes may be prepaid in whole or in part at any time, subject to payment of a make-whole amount; interest on the 2018 Notes is payable semiannually. At September 29, 2018, the Company was in compliance with the covenants under the 2018 NPA. In connection with the issuance of the 2018 Notes, on June 15, 2018, the Company repaid, on maturity $175.0 million in principal amount of its 5.20% Senior Notes (the “2011 Notes”). The Company also has a senior unsecured revolving credit facility (the “Credit Facility”), with a $300.0 million maximum commitment that expires on July 5, 2021. The Credit Facility may be further increased to $500.0 million, generally by mutual agreement of the Company and the lenders, subject to certain customary conditions. During fiscal 2018, the highest daily borrowing was $208.0 million; the average daily borrowings were $59.8 million. The Company borrowed $683.5 million and repaid $791.5 million of revolving borrowings under the Credit Facility during fiscal 2018. The Company was in compliance with all financial covenants relating to the Credit Agreement, which are generally consistent with those in the Note Purchase Agreements discussed above. The Company is required to pay a commitment fee on the daily unused revolver credit commitment based on the Company’s leverage ratio; the fee was 0.175% as of September 29, 2018. 60 Plexus Corp. Notes to Consolidated Financial Statements The aggregate scheduled maturities of the Company’s debt obligations as of September 29, 2018, are as follows (in thousands): 2019 2020 2021 2022 2023 Thereafter Total $ — — — — — 150,000 $150,000 The aggregate scheduled maturities of the Company’s capital leases and other financing obligations as of September 29, 2018, are as follows (in thousands): 2019 2020 2021 2022 2023 Thereafter Total $ 5,532 2,963 1,515 1,101 696 28,050 $39,857 The Company’s weighted average interest rate on capital lease obligations was 4.87% and 4.51% as of September 29, 2018 and September 30, 2017, respectively. The Neenah Design Center capital approximately $15.7 million, during fiscal 2017. lease commenced, and resulted in a non-cash transaction of The “Thereafter” line of the scheduled maturities of capital lease obligations table above includes an $8.8 million non-cash financing obligation related to a failed sale-leaseback of a building shell in Guadalajara, Mexico that was capitalized in fiscal 2014. This obligation will be increased by interest expense and land rent expense, and reduced by contractual payments during the 20-year lease term. As of September 30, 2017, the balance of the related financing obligation totaled $8.6 million. At the end of the 20-year lease term, the net book value of the assets will approximate the balance of the financing obligation. If the Company does not exercise both renewal options or exercises the first but not the second, it would record a loss related to the disposal of the underlying assets in operating results of $4.1 million in fiscal 2024 or $0.8 million in fiscal 2029. Construction on a second manufacturing facility in Guadalajara, Mexico began in fiscal 2018, resulting in an additional $7.2 million of non-cash financing obligations that were capitalized as of September 29, 2018. This obligation will be increased as construction costs are incurred and also by interest expense and land rent expense, and reduced by contractual payments during the 25-year lease term. This amount is included in the “Thereafter” line of the scheduled maturities of capital lease obligations table above, as well as in long-term debt and capital lease obligations, net of current portion, on the accompanying Consolidated Balance Sheets as of September 29, 2018. The lease contains a 15-year base lease agreement with two 5-year renewal options. 61 Plexus Corp. Notes to Consolidated Financial Statements The future minimum payments under the remainder of the two facilities in Guadalajara, leased under 10-year and 15-year base lease agreements, as well as the two 5-year renewal options for each lease are as follows (in thousands): 2019 2020 2021 2022 2023 Thereafter (2024 – 2044, through both five-year renewal options for each building) Total $ 3,328 4,301 4,409 4,520 4,632 100,159 $121,349 5. Derivatives and Fair Value Measurements All derivatives are recognized in the accompanying Consolidated Balance Sheets at their estimated fair value. The Company uses derivatives to manage the variability of foreign currency obligations. The Company has cash flow hedges related to forecasted foreign currency obligations, in addition to non-designated hedges to manage foreign currency exposures associated with certain foreign currency denominated assets and liabilities. The Company does not enter into derivatives for speculative purposes. The Company designates some foreign currency exchange contracts as cash flow hedges of forecasted foreign currency expenses. Changes in the fair value of the derivatives that qualify as cash flow hedges are recorded in “Accumulated other comprehensive loss” in the accompanying Consolidated Balance Sheets until earnings are affected by the variability of the cash flows. In the next twelve months, the Company estimates that $1.7 million of unrealized losses, net of tax, related to cash flow hedges will be reclassified from other comprehensive (loss) income into earnings. Changes in the fair value of the non-designated derivatives related to recognized foreign currency denominated assets and liabilities are recorded in “Miscellaneous income (expense)” in the accompanying Consolidated Statements of Comprehensive Income. The Company enters into forward currency exchange contracts for its operations in Malaysia and Mexico on a rolling basis. The Company had cash flow hedges outstanding with a notional value of $74.0 million as of September 29, 2018, and a notional value of $67.0 million as of September 30, 2017. These forward currency contracts fix the exchange rates for the settlement of future foreign currency obligations that have yet to be realized. The total fair value of the forward currency exchange contracts was a $1.7 million liability as of September 29, 2018, and a $2.0 million asset as of September 30, 2017. The Company had additional forward currency exchange contracts outstanding as of September 29, 2018, with a notional value of $28.6 million; there were $10.6 million such contracts outstanding as of September 30, 2017. The Company did not designate these derivative instruments as hedging instruments. The net settlement amount (fair value) related to these contracts is recorded on the Consolidated Balance Sheets as either a current or long- term asset or liability, depending on the term, and as an element of “Miscellaneous income (expense).” The total fair value of these derivatives was a $0.1 million liability as of both September 29, 2018 and September 30, 2017. On May 5, 2017, a $75.0 million notional amount interest rate swap contract expired related to $75.0 million of borrowings outstanding under the Credit Facility. The interest rate swap paid the Company variable interest at the one month LIBOR rate, and the Company paid the counterparty a fixed interest rate. The fixed interest rate for the contract was 0.875%. The interest rate swap contract qualified as a cash flow hedge and all changes in the fair value of the interest rate swap were recorded in “Accumulated other comprehensive loss” on the accompanying Consolidated Balance Sheets until earnings were affected by the variability of cash flows. 62 Plexus Corp.

Income Taxes The domestic and foreign components of income (loss) before income tax expense for fiscal 2018, 2017 and 2016 were as follows (in thousands): U.S. Foreign 2018 2017 2016 $ (53,243) 160,853 $ (35,209) 157,032 $ (26,796) 114,190 $107,610 $121,823 $ 87,394 Income tax expense (benefit) for fiscal 2018, 2017 and 2016 were as follows (in thousands): Current: Federal State Foreign Deferred: Federal State Foreign 2018 2017 2016 $63,814 234 10,134 74,182 $ 78 33 10,016 10,127 $ — (15) 11,312 11,297 (2,958) (447) 23,793 20,388 77 38 (481) (366) — 24 (354) (330) $94,570 $ 9,761 $10,967 64 Plexus Corp. Notes to Consolidated Financial Statements The following is a reconciliation of the federal statutory income tax rate to the effective income tax rates reflected in the Consolidated Statements of Comprehensive Income for fiscal 2018, 2017 and 2016: Federal statutory income tax rate Increase (decrease) resulting from: Permanent differences Foreign tax rate differences Excess tax benefits related to share-based compensation Disregarded entity benefit Dividend repatriation Valuation allowances Deemed repatriation tax Change in permanent reinvested assertion Rate changes Other, net 2018 2017 2016 24.5% 35.0% 35.0% 1.0 (30.2) (2.7) (0.5) — (30.6) 92.2 23.7 9.0 1.5 3.2 (39.9) (2.0) (0.9) — 12.2 — — — 0.4 1.6 (36.3) — (1.8) 32.9 (18.7) — — — (0.1) Effective income tax rate 87.9% 8.0% 12.6% On December 22, 2017, the U.S. Tax Cuts and Jobs Act was enacted (“Tax Reform”). Tax Reform made significant changes to U.S. corporate income tax, including transitioning the U.S. to a dividend exemption system and requiring a deemed dividend on historical undistributed earnings of foreign subsidiaries at a reduced tax rate. The Company recorded income tax expense of $94.6 million, $9.8 million and $11.0 million for fiscal 2018, 2017 and 2016, respectively. The $94.6 million of tax expense recorded during fiscal 2018 includes a provisional tax expense of $85.9 million related to Tax Reform. The components of the provisional tax expense include $61.2 million of U.S. federal and states taxes on deemed repatriation of historical undistributed foreign earnings, which are payable over an eight year period beginning in fiscal 2019, $21.8 million of foreign withholding taxes due to a change in the Company’s permanently reinvested assertion on foreign earnings that are payable upon repatriation to the U.S. and $2.9 million for unrecognized tax benefits related to the implementation of Tax Reform. The Company considers the tax expense recorded for Tax Reform to be complete at this time. However, it is possible that additional legislation, regulations and/or guidance may be issued within the provisional reporting period that may result in additional adjustments to the tax expense recorded related to Tax Reform. The effective tax rate for fiscal 2018 was higher than the effective tax rate for fiscal 2017 primarily due to expenses related to Tax Reform. The effective tax rate for fiscal 2017 is lower than that of fiscal 2016 primarily due to an increase in income before taxes in lower tax-rate jurisdictions and a tax benefit related to incremental deductible expenses in a jurisdiction where the Company pays income tax. During fiscal 2018, the Company recorded a $32.9 million reduction to its valuation allowance which includes $9.7 million related to the U.S. federal tax rate change as part of Tax Reform from 35% to 21%, $21.0 million of carryforward credits and net operating losses utilized against the deemed repatriation of undistributed foreign earnings and $3.6 million for the release of the U.S. valuation allowance due to the expected future U.S. taxable income related to the Global Intangible Low-Taxed Income provisions of Tax Reform. These benefits were partially offset by a $1.4 million increase in foreign valuation allowances in the EMEA segment. During fiscal 2017, the Company recorded a $14.9 million addition to its valuation allowance relating to continuing losses in certain jurisdictions within the AMER and EMEA segments. 65 Plexus Corp. Notes to Consolidated Financial Statements During fiscal 2016, the Company repatriated $100.0 million of current year foreign earnings from the APAC segment to the U.S., which had no income statement impact due to U.S. net operating losses, the use of U.S. tax credits and the reversal of the related valuation allowance. At that time, the repatriation did not impact the permanently reinvested assertions made by the Company regarding prior period foreign earnings as the remittance was distributed exclusively from fiscal 2016 foreign earnings. The components of the net deferred income tax assets as of September 29, 2018 and September 30, 2017, were as follows (in thousands): Deferred income tax assets: Loss/credit carryforwards Inventories Accrued benefits Other Total gross deferred income tax assets Less valuation allowances Deferred income tax assets Deferred income tax liabilities: Property, plant and equipment Tax on unremitted earnings Deferred income tax liabilities 2018 2017 $ 27,915 6,459 14,459 3,450 52,283 (28,369) 23,914 $ 44,831 7,710 25,811 3,051 81,403 (61,668) 19,735 12,530 14,935 27,465 14,443 — 14,443 Net deferred income tax assets/(liabilities) $ (3,551) $ 5,292 During fiscal 2018, the Company’s valuation allowance decreased by $33.3 million primarily due to the change in the U.S. federal tax rate from 35% to 21% and the U.S. valuation allowance being released due to the utilization of net operating losses against the deemed repatriation of undistributed foreign earnings and the expected future taxable income as a result of the Global Intangible Low-Taxed Income provisions of Tax Reform. This decrease is the result of a reduction to the valuation allowances against the net deferred tax assets in the AMER segment of $34.4 million and an increase in the EMEA segment of $1.1 million. As of September 29, 2018, the Company had approximately $174.7 million of pre-tax state net operating loss carryforwards that expire between fiscal 2019 and 2039. Certain state net operating losses have a full valuation allowance against them. The Company also had approximately $80.5 million of pre-tax foreign net operating loss carryforwards that expire between fiscal 2019 and 2024 or are indefinitely carried forward. These foreign net operating losses have a full valuation allowance against them. During fiscal 2018, tax legislation was adopted in various jurisdictions. The impacts of U.S. Tax Reform on the Company’s consolidated financial condition, results of operations and cash flows have been discussed above. No other legislative changes are expected to have a material impact on the Company’s consolidated financial condition, results of operations or cash flows. The Company has been granted a tax holiday for a foreign subsidiary in the APAC segment. This tax holiday will expire on December 31, 2024, and is subject to certain conditions with which the Company expects to continue to comply. During fiscal 2018, 2017 and 2016, the tax holiday resulted in tax reductions of approximately $39.1 million ($1.19 per basic share, $1.15 per diluted share), $37.5 million ($1.11 per basic share, $1.08 per diluted share) and $27.1 million ($0.81 per basic share, $0.79 per diluted share), respectively. 66 Plexus Corp. Notes to Consolidated Financial Statements The Company has approximately $5.8 million of uncertain tax benefits as of September 29, 2018. The Company has classified these amounts in the Consolidated Balance Sheets as “Other liabilities” (noncurrent) in the amount of $4.6 million and an offset to “Deferred income taxes” (noncurrent asset) in the amount of $1.2 million. The Company has classified these amounts as “Other liabilities” (noncurrent) and “Deferred income taxes” (noncurrent asset) to the extent that payment is not anticipated within one year. The following is a reconciliation of the beginning and ending amounts of unrecognized income tax benefits (in thousands): Balance at beginning of fiscal year Gross increases for tax positions of prior years Gross increases for tax positions of the current year Gross decreases for tax positions of prior years Balance at end of fiscal year 2018 2017 2016 $3,115 21 2,893 (188) $2,799 184 163 (31) $2,353 534 — (88) $5,841 $3,115 $2,799 The amount of unrecognized tax benefits that, if recognized, would impact the effective tax rate is $4.6 million and $0.8 million for the fiscal years ended September 29, 2018 and September 30, 2017, respectively. The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense. The total accrued penalties and net accrued interest with respect to income taxes was approximately $0.2 million for each of the fiscal years ended September 29, 2018, September 30, 2017 and October 1, 2016. The Company recognized less than $0.1 million of expense for accrued penalties and net accrued interest in the Consolidated Statements of Comprehensive Income for each of the fiscal years ended September 29, 2018, September 30, 2017 and October 1, 2016. It is possible that a number of uncertain tax positions may be settled within the next 12 months. Settlement of these matters is not expected to have a material effect on the Company’s consolidated results of operations, financial position and cash flows. The Company files income tax returns, including returns for its subsidiaries, with federal, state, local and foreign taxing jurisdictions. The following tax years remain subject to examination by the respective major tax jurisdictions: Jurisdiction Fiscal Years China Germany Mexico Romania United Kingdom United States Federal State 2013-2018 2014-2018 2013-2018 2012-2018 2015-2018 2011, 2013-2018 2003-2018 67 Plexus Corp. Notes to Consolidated Financial Statements 7. Earnings Per Share The following is a reconciliation of the amounts utilized in the computation of basic and diluted earnings per share for fiscal 2018, 2017 and 2016 (in thousands, except per share amounts): Net income 2018 2017 2016 $ 13,040 $ 112,062 $ 76,427 Basic weighted average common shares outstanding Dilutive effect of share-based awards outstanding Diluted weighted average shares outstanding 33,003 916 33,919 33,612 941 34,553 33,374 724 34,098 Earnings per share: Basic Diluted $ $ 0.40 0.38 $ $ 3.33 3.24 $ $ 2.29 2.24 In fiscal 2018, 2017 and 2016, share-based awards for approximately 0.1 million, 0.1 million and 0.8 million shares, respectively, were not included in the computation of diluted earnings per share as they were antidilutive. 8. Operating Lease Commitments The Company has a number of operating lease agreements primarily involving manufacturing facilities, manufacturing equipment and computerized design equipment. These leases are non-cancelable and expire on various dates through fiscal 2028, and many contain renewal and/or purchase options. Rent expense under all operating leases for fiscal 2018, 2017 and 2016 was approximately $12.0 million, $13.7 million and $13.6 million, respectively. Future minimum annual payments on operating leases are as follows (in thousands): 2019 2020 2021 2022 2023 Thereafter $9,518 9,129 5,119 3,627 3,582 7,653 Total future minimum operating lease payments $38,628 9. Benefit Plans Share-based Compensation Plans: The Plexus Corp. 2016 Omnibus Incentive Plan (the “2016 Plan”), which was approved by shareholders, is a stock and cash-based incentive plan, and includes provisions by which the Company may grant executive officers, employees and directors stock options, stock appreciation rights (“SARs”), restricted stock (including restricted stock units (“RSUs”), performance stock awards (including performance stock units (“PSUs”), other stock awards and cash incentive awards. Similar awards were offered under its predecessor, the 2008 Long-Term Incentive Plan (the “2008 Plan”), which is no longer being used for grants; however, outstanding awards granted under the 2008 Plan and its predecessors continue in accordance with their terms. The maximum number of shares of Plexus common stock that may be issued pursuant to the 2016 Plan is 3.2 million shares; in addition, cash incentive awards of up to $4.0 million per employee may be granted 68 Plexus Corp. Notes to Consolidated Financial Statements annually. The exercise price of each stock option and SAR granted must not be less than the fair market value on the date of grant. The Compensation and Leadership Development Committee (the “Committee”) of the Board of Directors may establish a term and vesting period for awards under the 2016 Plan as well as accelerate the vesting of such awards. Generally, stock options vest in two annual installments and have a term of ten years. SARs vest in two annual installments and have a term of seven years. RSUs granted to executive officers, other officers and key employees generally vest on the third anniversary of the grant date (assuming continued employment), which is also the date as of which the underlying shares will be issued. Beginning for fiscal 2017 grants, 50% of PSUs vest based on the relative total shareholder return (“TSR”) of the Company’s common stock as compared to the companies in the Russell 3000 Index, a market condition, and the remaining 50% vest based upon a three-point annual average of the Company’s absolute economic return, a performance condition, each during a three-year performance period. The PSUs granted in fiscal 2016 and prior years vest based solely on the relative TSR of the Company’s common stock as compared to companies in the Russell 3000 Index during a three-year performance period. The Committee also grants RSUs to non-employee directors, which generally fully vest on the first anniversary of the grant date, which is also the date the underlying shares are issued (unless further deferred). The Company recognized $18.0 million, $17.4 million and $19.3 million of compensation expense associated with share-based awards in fiscal 2018, 2017 and 2016, respectively. Deferred tax benefits related to equity awards of $8.2 million were recognized in fiscal 2018. No deferred tax benefits related to equity awards were recognized in fiscal 2017 or 2016.

The Company used its historical stock prices as the basis for its volatility assumptions. The assumed risk-free rates were based on U.S. Treasury rates in effect at the time of grant with a term consistent with the expected option and SAR lives. The expected options and SARs lives represent the period of time that the options and SARs granted are expected to be outstanding and were based on historical experience. There were no options or SARs granted for fiscal 2018. The weighted average fair value per share of options and SARs granted for fiscal 2017 and 2016 were $15.66 and $12.82, respectively. The fair value of each option and SAR grant was estimated at the date of grant using the Black-Scholes option-pricing model based on the assumption ranges below: Expected life (years) Risk-free interest rate Expected volatility Dividend yield 2017 5.70 1.50% 34% — 2016 5.70 1.23 - 1.87% 35 - 37% — The fair value of options and SARs vested for fiscal 2018, 2017 and 2016 was $1.3 million, $3.5 million and $3.6 million, respectively. For fiscal 2018, 2017 and 2016, the total intrinsic value of options and SARs exercised was $10.9 million, $10.2 million and $7.4 million, respectively. As of September 29, 2018, there was $0.1 million of unrecognized compensation expense related to non-vested options and SARs that is expected to be recognized over a weighted average period of 0.1 years. 70 Plexus Corp. Notes to Consolidated Financial Statements A summary of the Company’s PSU and RSU activity follows: Number of Shares (in thousands) Weighted Average Fair Value at Date of Grant Aggregate Intrinsic Value (in thousands) Units outstanding as of October 3, 2015 Granted Canceled Vested Units outstanding as of October 1, 2016 Granted Canceled Vested Units outstanding as of September 30, 2017 Granted Canceled Vested Units outstanding as of September 29, 2018 796 499 (29) (244) 1,022 397 (22) (329) 1,068 331 (42) (324) 1,033 $38.18 39.68 36.84 27.77 $41.49 54.21 41.17 43.76 $45.97 61.88 46.74 45.48 $51.19 $60,455 The Company uses the fair value at the date of grant to value RSUs. As of September 29, 2018, there was $16.7 million of unrecognized compensation expense related to RSUs that is expected to be recognized over a weighted average period of 1.3 years. The Company uses the Monte Carlo valuation model to determine the fair value of PSUs at the date of grant. Vesting of all PSUs granted in fiscal 2016 and prior years is based on the relative TSR of Plexus stock as compared to the TSR of companies in the Russell 3000 Index during a three-year performance period. Beginning in fiscal 2017, 50% of the PSUs will vest based on relative TSR performance, with the other 50% vesting based on a three-point annual average of the Company’s absolute economic return, each during a three-year performance period. The vesting and payout of awards will range between 0% and 200% of the shares granted based upon performance on the metrics during the performance period. Payout at target, 100% of the shares granted, will occur if the TSR of Plexus stock is at the 50th percentile of companies in the Russell 3000 Index during the performance period and if a 2.5% average economic return is achieved over the three-year performance period. The number of shares that may be issued pursuant to PSUs ranges from zero to 0.4 million. The Company recognizes share-based compensation expense over the vesting period of PSUs. During the fiscal year ended September 29, 2018, the 0.1 million PSUs granted in fiscal 2015 vested at a 146% payout based upon the TSR performance achieved during the performance period. There were 0.1 million PSUs granted during each of fiscal years 2018, 2017 and 2016. As of September 29, 2018, at the target achievement level, there was $7.7 million of unrecognized compensation expense related to PSUs that is expected to be recognized over a weighted average period of 1.9 years. 401(k) Savings Plan: The Company’s 401(k) Retirement Plan covers all eligible U.S. employees. The Company matches employee contributions up to 4.0% of eligible earnings. The Company’s contributions for fiscal 2018, 2017 and 2016 totaled $8.1 million, $7.5 million and $7.4 million, respectively. Deferred Compensation Arrangements: The Company has agreements with certain former executive officers to provide nonqualified deferred compensation. Under these agreements, the Company agrees to pay these former executives, or their designated beneficiaries upon such executives’ deaths, certain amounts annually for the first 71 Plexus Corp. Notes to Consolidated Financial Statements 15 years subsequent to their retirement. As of September 29, 2018 and September 30, 2017, the related deferred compensation liability associated with these arrangements totaled $0.2 million and $0.3 million, respectively. The Company maintains investments in a trust account to fund required payments under the deferred compensation plan. As of September 29, 2018 and September 30, 2017, the total value of the assets held by the trust totaled $10.0 million and $9.7 million, respectively, and was recorded at fair value on a recurring basis. These assets were classified as Level 2 in the fair value hierarchy discussed in Note 1, “Description of Business and Significant Accounting Policies.” During fiscal 2018, 2017 and 2016, the Company made payments to the participants in the amount of $0.1 million, $0.4 million and $0.8 million, respectively. Supplemental Executive Retirement Plan: The Company also maintains a supplemental executive retirement plan (the “SERP”) as an additional deferred compensation plan for executive officers. Under the SERP, a covered executive may elect to defer some or all of the participant’s compensation into the plan, and the Company may credit the participant’s account with a discretionary employer contribution. Participants are entitled to payment of deferred amounts and any related earnings upon termination or retirement from Plexus. The SERP allows investment of deferred compensation into individual accounts and, within these accounts, into one or more designated investments. Investment choices do not include Plexus stock. During fiscal 2018, 2017 and 2016, the Company made contributions to the participants’ SERP accounts in the amount of $1.0 million, $1.2 million and $0.5 million, respectively. In July 2018, the Company changed the trustee of the SERP. The change resulted in a settlement and re-investment of $11.3 million, with no actual cash received or distributed by the Company. In March 2017, the Company changed the trustee of the SERP. The change resulted in a settlement and re-investment of $10.3 million, with no actual cash received or distributed by the Company. As of September 29, 2018 and September 30, 2017, the SERP assets held in the trust totaled $11.7 million and $12.0 million, respectively, and the related liability to the participants totaled approximately $11.7 million and $12.0 million, respectively. As of September 29, 2018 and September 30, 2017, the SERP assets held in the trust were recorded at fair value on a recurring basis, and were classified as Level 2 in the fair value hierarchy discussed in Note 1, “Description of Business and Significant Accounting Policies.” The trust assets are subject to the claims of the Company’s creditors. The deferred compensation and trust assets and the related liabilities to the participants are included in non-current “Other assets” and non-current “Other liabilities,” respectively, in the accompanying Consolidated Balance Sheets. 10. Litigation The Company is party to lawsuits in the ordinary course of business. Management does not believe that these proceedings, individually or in the aggregate, will have a material positive or adverse effect on the Company’s consolidated financial position, results of operations or cash flows. 11. Reportable Segments, Geographic Information and Major Customers Reportable segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or group, in assessing performance and allocating resources. The Company uses an internal management reporting system, which provides important financial data to evaluate performance and allocate the Company’s resources on a regional basis. Net sales for the 72 Plexus Corp. Notes to Consolidated Financial Statements segments are attributed to the region in which the product is manufactured or the service is performed. The services provided, manufacturing processes used, class of customers serviced and order fulfillment processes used are similar and generally interchangeable across the segments. A segment’s performance is evaluated based upon its operating income (loss). A segment’s operating income (loss) includes its net sales less cost of sales and selling and administrative expenses, but excludes corporate and other expenses. Corporate and other expenses primarily represent corporate selling and administrative expenses, and restructuring costs and other charges, if any, such as the $13.5 million one-time employee bonus paid to full-time, non-executive employees during fiscal 2018 due to our ability to access overseas cash as a result of Tax Reform (the “one-time employee bonus”). Losses incurred from a typhoon that impacted the APAC segment in fiscal 2016 are excluded from the segment results and included within corporate and other expenses. These costs are not allocated to the segments, as management excludes such costs when assessing the performance of the segments. Inter-segment transactions are generally recorded at amounts that approximate arm’s length transactions. The accounting policies for the segments are the same as for the Company taken as a whole.

Long-lived assets as of September 29, 2018 and September 30, 2017 exclude other long-term assets, deferred income tax assets and intangible assets, which totaled $74.2 million and $44.1 million, respectively. 74 Plexus Corp. Notes to Consolidated Financial Statements As a percentage of consolidated net sales, net sales attributable to customers representing 10.0% or more of consolidated net sales for fiscal 2018, 2017 and 2016 were as follows: 2018 2017 2016 11.1% General Electric Company (“GE”) 10.4% Micron Technology, Inc. (“Micron”) ARRIS Group, Inc. (“Arris”) 10.1% * Net sales attributable to the customer were less than 10.0% of consolidated net sales for 12.3% * * 12.2% * * the period. During fiscal 2018, 2017 and 2016, net sales attributable to GE were reported in all three reportable segments. During fiscal 2016, sales attributable to Arris and Micron were reported in the AMER and APAC segments. As of September 29, 2018, GE represented 10.9% of total accounts receivable. As of September 30, 2017, Arris represented 11.6% of total accounts receivable. 12. Guarantees The Company offers certain indemnifications under its customer manufacturing agreements. In the normal course of business, the Company may from time to time be obligated to indemnify its customers or its customers’ customers against damages or liabilities arising out of the Company’s negligence, misconduct, breach of contract, or infringement of third party intellectual property rights. Certain agreements have extended broader indemnification, and while most agreements have contractual limits, some do not. However, the Company generally does not provide for such indemnities and seeks indemnification from its customers for damages or liabilities arising out of the Company’s adherence to customers’ specifications or designs or use of materials furnished, or directed to be used, by its customers. The Company does not believe its obligations under such indemnities are material. In the normal course of business, the Company also provides its customers a limited warranty covering workmanship, and in some cases materials, on products manufactured by the Company. Such warranty generally provides that products will be free from defects in the Company’s workmanship and meet mutually agreed-upon specifications for periods generally ranging from 12 months to 24 months. The Company’s obligation is generally limited to correcting, at its expense, any defect by repairing or replacing such defective product. The Company’s warranty generally excludes defects resulting from faulty customer-supplied components, design defects or damage caused by any party or cause other than the Company. The Company provides for an estimate of costs that may be incurred under its limited warranty at the time product revenue is recognized and establishes additional reserves for specifically identified product issues. These costs primarily include labor and materials, as necessary, associated with repair or replacement and are included in the Company’s accompanying Consolidated Balance Sheets in “other current accrued liabilities.” The primary factors that affect the Company’s warranty liability include the value and the number of shipped units and historical and anticipated rates of warranty claims. As these factors are impacted by actual experience and future expectations, the Company assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary. 75 Plexus Corp. Notes to Consolidated Financial Statements Below is a table summarizing the activity related to the Company’s limited warranty liability for fiscal 2018, 2017 and 2016 (in thousands): Limited warranty liability, as of October 3, 2015 Accruals for warranties issued during the period Settlements (in cash or in kind) during the period Limited warranty liability, as of October 1, 2016 Accruals for warranties issued during the period Settlements (in cash or in kind) during the period Limited warranty liability, as of September 30, 2017 Accruals for warranties issued during the period Settlements (in cash or in kind) during the period $ 5,847 1,777 (1,515) 6,109 912 (2,265) 4,756 5,608 (3,718) Limited warranty liability, as of September 29, 2018 $ 6,646 13. Shareholders’ Equity On February 14, 2018, the Board of Directors approved a new stock repurchase plan under which the Company is authorized to repurchase $200.0 million of its common stock (the “2018 Program”). The 2018 Program commenced upon completion of the 2016 Program, as defined below. During fiscal 2018, the Company repurchased 343,642 shares under this program for $21.2 million, at an average price of $61.61 per share. As of September 29, 2018, $178.8 million of authority remained under the 2018 Program. On June 6, 2016, the Board of Directors authorized a multi-year stock repurchase program under which the Company was authorized to repurchase up to $150.0 million of its common stock beginning in fiscal 2017 (the “2016 Program”). During fiscal 2018 and 2017, the Company completed the 2016 Program by repurchasing 1,914,596 and 655,470 shares for $115.9 million and $34.1 million, at an average price of $60.52 and $52.08 per share, respectively. On August 20, 2015, the Board of Directors authorized a stock repurchase program under which the Company was authorized to repurchase up to $30.0 million of its common stock during fiscal 2016. During fiscal 2016, the Company repurchased 760,903 shares for $30.0 million, at an average price of $39.43 per share. All shares repurchased under the aforementioned programs were recorded as treasury stock. 14. Trade Accounts Receivable Sale Programs The Company has Master Accounts Receivable Purchase Agreements with MUFG Bank, New York Branch, formerly known as The Bank of Tokyo-Mitsubishi UFJ, Ltd. (the “MUFG RPA”), and HSBC Bank (China) Company Limited, Xiamen branch (the “HSBC RPA”), under which the Company may elect to sell receivables, at a discount, on an ongoing basis. The MUFG RPA was amended on September 19, 2018, to increase the maximum facility amount from $210.0 million to $230.0 million. The maximum facility amount under the HSBC RPA as of September 29, 2018 is $60.0 million. The MUFG RPA is subject to expiration on October 3, 2019, but will be automatically extended each year unless any party gives no less than 10 days prior notice that the agreement should not be extended. The terms of the HSBC RPA are generally consistent with the terms of the MUFG RPA discussed above. The Company sold receivables under a former trade accounts receivable sale program that expired during the first fiscal quarter of 2017. 76 Plexus Corp. Notes to Consolidated Financial Statements Transfers of receivables under the programs are accounted for as sales and, accordingly, receivables sold under the programs are excluded from accounts receivable on the Consolidated Balance Sheets and are reflected as cash provided by operating activities on the Consolidated Statements of Cash Flows. Proceeds from the transfer reflect the face value of the receivables less a discount. The sale discount is recorded within “Miscellaneous expense” in the Consolidated Statements of Comprehensive Income in the period of the sale. The Company sold $712.9 million, $418.0 million and $65.6 million of trade accounts receivable under these programs, or their predecessors, during fiscal years 2018, 2017 and 2016, respectively, in exchange for cash proceeds of $708.6 million, $415.8 million and $65.0 million, respectively. 15. Acquisition On July 27, 2018, the Company purchased the assets of one of the business lines of Cascade Controls, Inc. (“Cascade”), a new product introduction company in Portland, Oregon, for $12.4 million in cash, subject to certain customary post-closing adjustments. Plexus acquired substantially all of the inventory, equipment and other assets of the business line, hired a majority of its employees and sub-leased one of Cascade’s facilities. This transaction has been accounted for as a business combination. The acquisition resulted in a $12.4 million cash outflow included in “Business acquisition” in the accompanying Consolidated Statement of Cash Flows and $8.2 million of intangible assets related to customer relationships, which is included in “Intangible assets” in the accompanying Consolidated Balance Sheet. The intangible assets will be amortized on a straight-line basis and result in amortization expense for fiscal 2019, 2020, 2021, 2022 and 2023 of approximately $1.2 million per year. There were no other material impacts to the Company’s Consolidated Financial Statements as a result of the acquisition. 16. Restructuring Costs The Company incurred no restructuring costs during fiscal 2018 or 2017. During fiscal 2016 the Company recorded $7.0 million of restructuring costs related largely to the Company’s closure of its manufacturing facility in Fremont, California. The Company also recorded restructuring costs in the EMEA segment in fiscal 2016 related to the partial closure of its Livingston, Scotland facility. These charges are recorded within “Restructuring costs” on the Consolidated Statements of Comprehensive Income. Restructuring liabilities are recorded within “Other accrued liabilities” in the Consolidated Balance Sheets. No income tax benefit for these restructuring costs was recognized in fiscal 2017 or 2016 due to tax losses in these jurisdictions. 77 Plexus Corp.

(2) The first quarter of fiscal 2018 results included $124.5 million of tax expense as a result of the enactment of Tax Reform. The fourth quarter of fiscal 2018 results included $38.6 million of non-recurring tax benefits as well as a $3.6 million benefit due to the reversal of a valuation allowance on U.S. deferred tax assets. These benefits were partially offset by $1.1 million of tax expense for other non-recurring tax items. Refer to Note 6, “Income Taxes,” for further details on Tax Reform. (3) The annual total amounts may not equal the sum of the quarterly amounts due to rounding. Earnings per share is computed independently for each quarter. 78 Plexus Corp. Notes to Consolidated Financial Statements (4) The first quarter of fiscal 2018 includes $3.59 per share of tax expense as a result of the enactment of U.S. Tax Reform and $0.09 per share that resulted from 1.1 million of weighted average potentially- dilutive shares that were excluded from the diluted shares calculation due to the net loss position. The second quarter of fiscal 2018 includes $0.38 per share of expense related to the one-time employee bonus. The fourth quarter of fiscal 2018 includes $1.24 per share of non-recurring tax benefits. 79 ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE None. ITEM 9A. CONTROLS AND PROCEDURES Disclosure Controls and Procedures The Company maintains disclosure controls and procedures designed to ensure that the information the Company must disclose in its filings with the Securities and Exchange Commission (“SEC”) is recorded, processed, summarized and reported on a timely basis. The Company’s Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”) have reviewed and evaluated, with the participation of the Company’s management, the Company’s disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) as of the end of the period covered by this report. Based on such evaluation, the CEO and CFO have concluded that, as of September 29, 2018, the Company’s disclosure controls and procedures are effective, at the reasonable assurance level, (a) in recording, processing, summarizing and reporting, on a timely basis, information required to be disclosed by the Company in the reports the Company files or submits under the Exchange Act, and (b) in assuring that information is accumulated and communicated to the Company’s management, including the CEO and CFO, as appropriate to allow timely decisions regarding required disclosure. Management’s Annual Report on Internal Control Over Financial Reporting Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Management of the Company, including its CEO and CFO, has assessed the effectiveness of its internal control over financial reporting as of September 29, 2018, based on the criteria established in “Internal Control – Integrated Framework” issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) (2013). Based on its assessment and those criteria, management has reached the conclusion that the Company’s internal control over financial reporting was effective at the reasonable assurance level. The independent registered public accounting firm of PricewaterhouseCoopers LLP has audited the Company’s internal control over financial reporting as of September 29, 2018, as stated in its report included herein. Changes in Internal Control Over Financial Reporting There have been no changes in the Company’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the Company’s most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting. Limitations on the Effectiveness of Controls Our management, including our CEO and CFO, does not expect that our disclosure controls and internal controls will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple errors or mistakes. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management 80 override of the control. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, a control may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected. Notwithstanding the foregoing limitations on the effectiveness of controls, we have nonetheless reached the conclusion that the Company’s disclosure controls and procedures and internal control over financial reporting are effective at the reasonable assurance level.
