OVERVIEW

Flex is the advanced, end-to-end manufacturing partner of choice that helps a diverse customer base design, build, deliver and manage products that improve the world. Through the collective strength of a global workforce across approximately 30 countries with responsible, sustainable operations, we deliver technology innovation, supply chain, and manufacturing solutions to diverse industries and end markets.

The Company’s full suite of specialized capabilities includes design and engineering, supply chain, manufacturing, and integrated services, plus a portfolio of power and cooling products. Over time, we have built differentiated scale and expertise across both technology-driven and regulated markets, enabling us to support customers with increasingly complex product, infrastructure, and compliance requirements. We partner with customers across a diverse set of industries including data center, healthcare, industrial, automotive, communications, and lifestyle.

Reflecting the evolution of our portfolio and operating model, as of March 31, 2026, Flex's three operating and reportable segments were as follows, to serve distinct customer needs and end markets:

• Integrated Technology Solutions ("ITS"), which is comprised of the following end markets:

◦Communications, high speed networking, enterprise, and satellite communications systems

◦Lifestyle, premium products across commercial, home and personal product categories

• Regulated Manufacturing Solutions ("RMS"), which is comprised of the following end markets:

◦Industrial, mission-critical automation, energy, and industrial infrastructure

◦Automotive, compute and power electronics platforms, and integrated systems

◦Healthcare, regulated manufacturing for medical devices, drug delivery and equipment

• Cloud and Power Infrastructure ("CPI"), which is comprised of the following end markets:

◦Cloud and Cooling, integrated compute systems supporting power‑dense digital infrastructure deployments, and advanced liquid cooling solutions supporting higher-density, power-intensive rack architectures

◦Power, utility and facility‑level electrical infrastructure enabling reliable, scalable power delivery and high-density rack- and board-level power systems supporting power-intensive compute workloads

Our ITS segment serves customers building technology-driven, intelligent products that require fast innovation cycles, while our RMS segment focuses on regulated, safety-critical markets requiring a high level of precision, compliance, and reliability. Together, ITS and RMS represent Flex’s core design and engineering, advanced manufacturing and supply chain

solutions business, combining product‑centric innovation, regulated manufacturing expertise, and global execution at scale. These segments leverage a shared operating model, established manufacturing and supply chain infrastructure, and disciplined processes to serve customers across diversified end markets with varying complexity, regulatory requirements, and product lifecycles.

Our new CPI segment is focused on delivering integrated compute systems, power, and cooling technologies that support large-scale cloud, data center, and AI-enabled infrastructure deployments. CPI programs are characterized by systems-level integration, high power density requirements, proprietary engineering and complex global manufacturing and supply chain execution, including capabilities that extend across rack‑level systems through facility and utility-level electrical infrastructure.

On May 5, 2026, following a comprehensive strategic and operational review by our Board of Directors and management team, we announced our intention to separate the Company into two independent, publicly traded companies: one comprising our CPI segment and the other comprising our advanced manufacturing and supply chain solutions business consisting of our ITS and RMS segments. The transaction is intended to qualify as a tax-free transaction for U.S. federal income tax purposes for the Company’s shareholders. The spin-off is targeted for completion in the first quarter of calendar 2027, subject to certain customary conditions, including, among others, final approval by our Board of Directors, shareholders, and the High Court of the Republic of Singapore and compliance with applicable SEC requirements. There can be no assurance that any spin-off transaction will ultimately occur or, if one does occur, of its terms or timing. See Item 1A, "Risk Factors - Planned Spin-off Risks—The planned spin-off of our Cloud and Power Infrastructure businesses may not be completed on the terms or timeline currently contemplated, if at all, and there is no guarantee that the spin-off, if completed, will achieve the intended financial, strategic, and operational benefits."

In fiscal year 2026, our ten largest customers accounted for 45% of net sales. No customer accounted for greater than 10% of the Company's net sales in fiscal year 2026.

On January 2, 2024, the Company completed its previously announced spin-off of its remaining interests in Nextracker Inc. ("Nextracker") to Flex shareholders on a pro-rata basis based on the number of ordinary shares of Flex held by each shareholder of Flex (the "Distribution") as of December 29, 2023, which was the record date of the Distribution, pursuant to the Agreement and Plan of Merger, dated as of February 7, 2023. The historical financial results and financial position of our former Nextracker business, which was previously reported as a separate operating and reportable segment, are presented as discontinued operations in the consolidated statements of operations. The historical statements of comprehensive income and cash flows and the balances related to stockholders’ equity have not been revised to reflect the effect of the Nextracker spin-off. See note 7 "Discontinued Operations & Noncontrolling Interest" to the consolidated financial statements in Item 8, "Financial Statements and Supplementary Data" for further information.

Industrial Parks; Cost-Efficient Manufacturing Services. We have developed self-contained industrial parks that co-locate manufacturing and logistics operations with our suppliers in various cost-efficient locations. These sites enhance supply chain management efficiency, while providing multi-technology solution value for our customers.

HUMAN CAPITAL MANAGEMENT

Culture underlies our stakeholder experience. Our values are intended to reflect and guide our behaviors and shape our culture. We endeavor for our values-driven culture to align us as we pursue our purpose, uphold our mission, live our values, advance toward our vision, and execute our strategy.

In support of cultivating a high-performing culture within our workforce, we continue to proliferate our "Ways of Working", four specific behaviors that bring our values to life through actions, provide a framework for how we make decisions, and support ongoing progress on our "Flex Forward" strategy. The purpose of these behaviors is to enable us to put our culture into practice and provide an accountability system through training and development as well as performance management systems to ensure our desired behaviors become a part of our everyday working norms. Building on our vision, mission, values, and Ways of Working, we use this framework to assess, hire, train, and nurture our talent to develop the skills necessary for our ongoing success.

How we live our values defines our culture:

• We support each other as we strive to find a better way.

• We move fast with discipline and purpose.

• We do the right thing always.

We bring our values to life through four behaviors:

1.Respect and value others.

2.Collaborate and share openly.

3.Learn and adapt.

4.Honor commitments.

We believe that the performance of our Company is impacted by our human capital management, and as a result we consistently work to attract, select, develop, engage and retain strong talent.

Our purpose, vision, mission and value statements aim to cultivate a high-performing culture where employees are empowered and given opportunities to reach their full potential. We are committed to providing a positive and safe workplace for our employees. Further, we are committed to respecting the human rights of our employees and improving their quality of life. Our leaders guide our teams to execute our strategy by focusing on building and developing our people, defining and driving our strategy, and delivering results.

Employees. As of March 31, 2026, our global workforce totaled approximately 150,000 employees including our contractor workforce. In certain international locations, our employees are represented by labor unions and by work councils.

Well-being, Health, and Safety. Flex is committed to providing a safe and injury-free workplace. We provide programs and tools to improve physical, mental, financial, and social well-being. Our programs give access to a variety of innovative, flexible, and convenient health and wellness programs for our global employees, including on-site health centers in some of our major factories and providing 100% of employees access to emotional and mental health programs.

We promote a "zero-injury" culture through health and safety management systems, some of which are certified ISO 45001:2018, that implement a data-driven and risk-based approach in monitoring and reporting performance regularly. Some of

the specific goals for which we measure our performance include increasing employee development, social and environmental management system audits, human rights policy training completion, and Responsible Business Alliance ("RBA") compliance for rest day requirements and decreasing safety incident rates.

Talent Attraction, Development, and Retention. Talent attraction, development, and retention are critical to our success and core to our mission as a company. To support the advancement of our employees, we provide training and development programs and opportunities encouraging advancement from within, and we also continue to fill our team with strong and experienced external talent. We leverage both formal and informal programs, including in-person, virtual, social and self-directed learning, mentoring, coaching, and external development to identify, foster, and retain top talent. Employees have access to courses through our learning and development platform, Flex Learn. In calendar year 2025, our employees completed more than five million hours of training programs.

We are also focused on completing talent and performance reviews. Our in-depth talent reviews serve to identify high potential talent to advance in roles with greater responsibility, assess learning and development needs, and establish and refresh succession plans for critical leadership roles across the enterprise. Our Ways of Working are integrated into our talent assessment and performance assessment processes. Our performance assessment process promotes transparent communication of team member performance, which we believe is a key factor in our success. The performance and the talent reviews enable ongoing assessments, reviews, and mentoring to identify career development and learning opportunities for our employees.

Employee Engagement. To attract and retain the best talent, we strive to establish a culture where our team members can freely contribute their differentiated perspectives, ideas, and experiences, and have opportunities to grow professionally and develop to their highest potential. As a part of our efforts to improve employee experiences at Flex, we conduct the annual enterprise-wide employee engagement Flex Voice survey. Our leadership uses the results of the survey to continue developing our strengths and identify and take action on opportunities for improvement. In fiscal year 2026, 95% of employees completed the Flex Voice survey and the results reflected continued engagement.

Compensation and Benefits. Our total rewards are designed to attract, motivate and retain employees. Our compensation philosophy is driven by the desire to attract and retain top talent, while ensuring that compensation aligns with our corporate financial objectives and the long-term interests of our shareholders. Our pay structures offer competitive salaries, bonuses, and equity awards in the countries where we operate.

In each of the countries where we have operations, our comprehensive benefit plans offer a locally competitive mix of some or all of the following: medical, dental and vision insurance, short and long-term disability, flexible spending accounts, various types of voluntary coverage, and other benefit programs. We routinely benchmark our salaries and benefits against market peers to ensure our total rewards package remains competitive.

Board Oversight of Human Capital Management. The Compensation and People Committee of our Board of Directors is responsible for assisting the Board in oversight of our human capital management, including among other aspects, receiving periodic updates regarding, and overseeing any significant change to our human capital management strategy including, corporate culture, compensation policies and practices, and talent attraction training, development and retention programs.

SUSTAINABILITY

At Flex, our sustainability journey began in 2002 with the creation of the Flex Foundation. For more than 20 years, sustainability has been integrated into the fabric of our company, a key area of differentiation for Flex. We've continued to progress against our 2030 sustainability strategy and commitments. Our sustainability framework is centered on three pillars: our world, our people, and our approach to ethical business practices, and guides our commitments, policies, and management processes across our global operations.

Our sustainability commitments focus on areas where we believe we can make measurable and meaningful progress, including reducing our environmental impact, advancing responsible supply chain practices, investing in our people and communities, and driving ethical business conduct. These commitments are aligned with the principles set forth in the United Nations 2030 Sustainable Development Goals ("SDGs") and grounded in internationally recognized standards, including the Responsible Business Alliance ("RBA") Code of Conduct, the world's largest industry coalition dedicated to promoting responsible business practices in global supply chains, ISO 14001, and the United Nations Guiding Principles on Business and Human Rights.

In 2022, we announced our commitment to reach net zero greenhouse gas ("GHG") emissions by 2040, strengthening our climate action efforts.

Recognition and Awards. During calendar year 2025, we received several awards and accolades for our sustainability program and efforts, including being named a World's Best Company by TIME and Statista for the third consecutive year. We also received recognition from our customers, including being named a top-performing supplier at Ford's annual Supplier

Awards ceremony, recognizing our excellence in sustainable manufacturing and our leadership in developing scalable solutions for automotive product-level emissions transparency. Flex was recently recognized as one of the 2026 World’s Most Ethical Companies® by the Ethisphere Institute.

Flex Foundation. Through the Flex Foundation, we work with nonprofits, community leaders and governments to advance global calls to action spanning targeted UN SDGs: #3 good health and well-being, #8 decent work and economic growth, #12 responsible consumption and production, and #13 climate action. The Flex Foundation helps support environmental and social causes in the communities we serve as well as provides disaster relief through grants, corporate and employee donations, and volunteerism. In calendar year 2025, the Flex Foundation collaborated with several organizations as part of our recurring community engagement cycles, including Give2Asia, Planet Water Foundation, and MidWest Food Bank. These partnerships also enabled us to support disaster relief efforts in coordination with organizations such as the American Red Cross, Mercy Chefs, and the Indonesian Red Cross (PMI).

Flex is committed to transparency in sustainability reporting. Since 2013, the Company has adhered to the Global Reporting Initiative (GRI) framework and has published an annual sustainability report. The Company also aligned its sustainability report to the Sustainability Accounting Standards Board (SASB) framework. In addition, the Company produced its first Task Force on Climate-related Financial Disclosures (TCFD) report in 2022 and issued an updated report in 2025.

More detailed information can be found in the Flex annual sustainability report located at https://flex.com/company/our-sustainability. The information in the sustainability report and on our sustainability webpage is not a part of this Annual Report on Form 10-K and is not incorporated by reference.

ENVIRONMENTAL RISKS AND CLIMATE CHANGE

We are subject to a variety of extensive and changing federal, state, local and international environmental, health and safety, product safety and stewardship, and producer responsibility laws and regulations, including those concerning, among other things, the health and safety of our employees, the generation, use, storage, transportation, discharge and disposal of certain materials (including chemicals and hazardous materials) used in or derived from our operations, the investigation and remediation of contaminated sites, and climate change and other sustainability-related matters. We have implemented processes and procedures aimed to ensure that our operations comply with all applicable laws and regulations.

We do not believe that costs of compliance with these laws and regulations will have a material adverse effect on our capital expenditures, operating results, or competitive position. In addition, we are responsible for cleanup of contamination at some of our current and former manufacturing facilities and at some third-party sites. We engage environmental consulting firms to assist us in the evaluation of environmental liabilities associated with our ongoing operations, historical disposal activities, and closed sites in order to establish appropriate accruals in our financial statements. We determine the amount of our accruals for environmental matters by analyzing and estimating the probability of occurrence and the reasonable possibility of incurring costs in light of information currently available.

Compliance with laws and regulations requires continuing management efforts by the Company. The imposition of more stringent standards or requirements under these laws or regulations, the results of future testing and analysis undertaken by us at our operating facilities, or a determination that we are potentially responsible for the release of hazardous substances at other sites could result in expenditures in excess of amounts currently estimated to be required for such matters. Additionally, we could be required to alter our operations in order to comply with any new standards or requirements under these laws or regulations. There can be no assurance that additional environmental matters will not arise in the future or that costs will not be incurred with respect to sites as to which no issue is currently known.

Our business requires close collaboration with our customers and suppliers to mitigate risks of non-compliance with these laws and regulations. We have developed rigorous compliance programs designed to meet the needs and specifications of our customers as well as applicable regulations. These programs vary from collecting compliance or material data from our Flex controlled or managed suppliers to full laboratory testing. We include compliance requirements in our standard supplier contracts. Non-compliance could result in significant costs and/or penalties.

Restrictions on Hazardous Substances ("RoHS") 2011/65/EU and other similar legislation ban or restrict the use of lead, mercury and certain other specified substances in electronics products and Waste Electrical and Electronic Equipment ("WEEE") 2012/19/EU directives requires European Union ("EU") importers and/or producers to assume responsibility for the collection, recycling and management of waste electronic products and components. In the case of WEEE, although the compliance responsibility rests primarily with the EU importers and/or producers rather than with electronic manufacturing services ("EMS") companies, original equipment manufacturers ("OEM") may turn to EMS companies for assistance in meeting their WEEE obligations. Flex continues to monitor developments related to product environmental compliance and is working with our customers and other technical organizations to anticipate and minimize impacts to our operations.

Refer to the discussion in Item 1A, "Risk Factors" for further details of the legal and regulatory initiatives related to environmental matters including climate change that could adversely affect our business, results of operations and financial condition.

INTELLECTUAL PROPERTY

We own or license various United States and foreign patents relating to a variety of technologies. For certain of our proprietary processes, inventions, and works of authorship, we rely on trade secret or copyright protection. We also maintain trademark rights (including registrations) for our corporate name and several other trademarks and service marks that we use in our business in the United States and other countries throughout the world. We have implemented appropriate policies and procedures (including both technological means and training programs for our employees) to identify and protect our intellectual property, as well as that of our customers and suppliers. As of March 31, 2026, and 2025, the carrying value of our intellectual property was not material.

Although we believe that our intellectual property assets and licenses are sufficient for the operation of our business as we currently conduct it, we do not consider any single patent, trademark, or license to be material to our business as a whole. From time to time, third parties may assert patent or other intellectual property infringement claims against us or our commercial partners and, in some cases, we may have liability exposure related to such assertions even if directed against our commercial partners. In addition, we provide design and engineering services to our customers and also design and make our own products. As a consequence of these activities, our customers sometimes require us to take responsibility for intellectual property to a greater extent than in our manufacturing and assembly businesses. Intellectual property disputes can be costly and time-consuming and, if resolved adversely, could require us to obtain licenses on unfavorable terms, pay damages, or modify or cease offerings. If and when third parties make assertions regarding the ownership or right to use intellectual property, we could be required to either enter into licensing arrangements or to resolve the issue through litigation. Such license rights might not be available to us on commercially acceptable terms, if at all, and any such litigation might not be resolved in our favor. Additionally, litigation could be lengthy and costly and could materially harm our financial condition regardless of the outcome. We also could be required to incur substantial costs to redesign a product or re-perform design and engineering services. For additional information, see Item 1A, "Risk Factors - Inadequate protection of our intellectual property and exposure to third-party intellectual property claims could adversely affect our business and results of operations" and "-Risks and uncertainties related to the development and use of AI could harm our business, damage our reputation, or give rise to legal or regulatory action."

Our business, financial condition, results of operations and prospects are subject to various risks and uncertainties, including those described below. You should carefully consider the following risks and all of the other information contained in this report, including our consolidated financial statements and related notes, before investing in any of our securities. The risks and uncertainties described below reflect management’s beliefs as to material risks and are not the only risks we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that materially adversely affect our business. If any of the following risks, or other risks and uncertainties that are not yet identified or that we currently think are immaterial, actually occur, our business, financial condition, results of operations and prospects could be materially and adversely affected. In that event, the market price of our ordinary shares could decline. References to past events are provided by way of example only. We may amend, supplement or add to the risk factors described below from time to time in future reports filed with the SEC.

Risk Management and Strategy

Our cybersecurity risk management program is intended to protect the confidentiality, integrity, and availability of our critical information technology ("IT") systems and data. We have integrated this program into our broader enterprise risk management framework, which is designed to identify, assess, prioritize and mitigate risks across the organization to enhance our resilience and support the achievement of our strategic objectives. We have designed and assess our cybersecurity risk management program based on multiple cybersecurity frameworks, including the National Institute of Standards and Technology Cybersecurity Framework ("NIST 2.0 CSF") and information security standards issued by the International Organization for Standardization, including ISO 27001. These frameworks guide us in identifying, assessing, and managing cybersecurity risks relevant to our business. Our global information security management program is ISO 27001:2022 certified.

Our cybersecurity risk management program is led by our Chief Information Officer (“CIO”) on an interim basis, supported by our security team principally responsible for managing our cybersecurity risk assessment processes, security controls, and detection and response to cybersecurity incidents. Our program includes protocols for preventing, detecting, and responding to cybersecurity incidents, as well as cross-functional coordination of business continuity and disaster recovery plans. Key components of our program include:

• risk assessments designed to help identify cybersecurity threats to our critical IT systems, information, and our broader enterprise IT environment;

• the periodic engagement of independent security firms and other third-party experts, where appropriate, to assess, test, and certify components of our cybersecurity program, and to otherwise assist with aspects of our cybersecurity processes and controls;

• annual cybersecurity awareness training for our employees;

• regular assessments of the design and operational effectiveness of the program’s key processes and controls by our internal audit team as well as external consultants; and

• a risk management process for third-party service providers and vendors that includes security due diligence during the selection process, contractual security requirements, and periodic monitoring of adherence to applicable cybersecurity standards.

We maintain a cybersecurity incident response plan that establishes procedures to assess and manage cybersecurity incidents. The plan includes escalation protocols based on the nature and severity of the incident, including escalation to the Audit Committee and the Board when appropriate. We conduct tabletop exercises at least annually to test our incident response procedures, identify gaps, and evaluate team preparedness.

As part of our overall risk mitigation strategy, we maintain insurance coverage intended to address certain aspects of cybersecurity risks. However, this insurance may not be sufficient in type or amount to cover all claims related to cybersecurity breaches, cyberattacks, or other related incidents.

As of the date of this report, we do not believe that any risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, have materially affected or are reasonably likely to materially affect our Company, including our business strategy, results of operations or financial condition. Despite our security measures, however, there can be no assurance that we, or third parties with which we interact, will not experience a cybersecurity incident in the future that could materially affect us. For more information on our cybersecurity-related risks, see Item 1A, "Risk Factors - A breach of our IT or physical security systems, or a cybersecurity incident affecting our operations, products, or third parties upon which we rely, could materially disrupt our business, damage our reputation, and expose us to significant costs and liability."

Governance

The Audit Committee of our Board of Directors has primary oversight responsibility for cybersecurity risks and other information technology risks. This oversight includes reviewing our plans to mitigate cybersecurity risks and our preparedness to respond to data breaches or other cybersecurity incidents.

The Audit Committee receives reports on cybersecurity matters at least quarterly from our Chief Information Security Officer ("CISO") (and currently on an interim basis, our CIO). These reports cover a range of topics, including our cybersecurity risk profile, the current and emerging threat landscape, the status of ongoing cybersecurity initiatives, incident reports, and the results of internal and external assessments. The Audit Committee also annually reviews the adequacy and effectiveness of our information security policies and related internal controls, and receives periodic updates from our internal

audit function on the results of cybersecurity audits and related mitigation activities. The Chair of the Audit Committee reports to the full Board on these matters as appropriate.

The full Board also receives briefings on cybersecurity matters annually from our CISO (and currently on an interim basis, our CIO). In addition, Board members periodically receive presentations on cybersecurity topics from external experts as part of the Board’s continuing education and overall risk oversight responsibilities.

At the management level, our CIO has assumed interim oversight of our enterprise-wide cybersecurity program following the departure of our former CISO in April 2026. In this role, he monitors the prevention, detection, mitigation, and remediation of cybersecurity risks and incidents through participation in the cybersecurity risk management and strategy processes described above, including the operation of our incident response plan. Our CIO reports to our Chief Operating Officer, a member of our executive leadership team.

Our CIO has over 20 years of experience in information technology and has led teams in the design, implementation, and continuous improvement of enterprise-wide digital and cybersecurity programs. Our CIO has managed material risks from cybersecurity threats, including the development and operation of incident response plans. Our CIO holds a Bachelor's degree in Computer Engineering and a Master's degree in Information Technology.

We own or lease facilities located primarily in the geographies listed below. Our facilities consist of a global network of industrial parks, regional manufacturing operations, and design, engineering and product introduction centers. The majority of the square footage is active manufacturing space used by our ITS, RMS and CPI operating segments. Our facilities are well maintained and suitable for the operations conducted. The productive capacity of our plants is adequate for current needs.

As of March 31, 2026, the square footage of our facilities by region is as follows:

(1)Consists of 23.9 million square feet in facilities that we own with the remaining 26.5 million square feet in leased facilities.

For a description of our material legal proceedings, see note 14 "Commitments and Contingencies" to the consolidated financial statements included under Item 8, which is incorporated herein by reference.

PART II

MARKET AND SHAREHOLDER INFORMATION

Our ordinary shares are quoted on the Nasdaq Global Select Market under the symbol "FLEX."

As of May 14, 2026, there were 2,678 holders of record of our ordinary shares. This does not include persons whose stock is in nominee or "street name" accounts through brokers.

DIVIDENDS

Since inception, we have not declared or paid any cash dividends on our ordinary shares. We currently do not have plans to pay any cash dividends in fiscal year 2027.

CERTAIN TAXATION CONSIDERATIONS UNDER SINGAPORE LAW

Dividends. Singapore does not impose a withholding tax on dividends. All dividends on our ordinary shares are not taxable in Singapore to shareholders, provided that any dividends are paid to shareholders outside of Singapore for this purpose and such dividends are not received or deemed to be received in Singapore by shareholders and are not derived by shareholders pursuant to any trade or business carried on in Singapore. Certain tax exemptions are available for foreign-sourced dividends received by Singapore tax residents, subject to conditions. Since inception, we have not declared nor paid any cash dividends on our ordinary shares, and we currently do not have plans to pay any cash dividends.

Gains on Disposal. Under current Singapore tax law there is no tax on capital gains, and thus any profits from the disposal of shares are not taxable in Singapore unless the gains arising from the disposal of shares are income in nature and subject to tax, especially if they arise from activities which the Inland Revenue Authority of Singapore regards as the carrying on of a trade or business in Singapore (in which case, the profits on the sale would be taxable as trade or business profits rather than capital gains).

Shareholders who apply, or who are required to apply, the Singapore Financial Reporting Standard ("FRS") 39, FRS 109 or Singapore Financial Reporting Standard (International) 9 ("SFRS(I) 9") (as the case may be) for the purposes of Singapore income tax may be required to recognize gains or losses (not being gains or losses in the nature of capital) in accordance with the provisions of FRS 39, FRS 109 or SFRS(I) 9 (as the case may be) (as modified by the applicable provisions of Singapore income tax law) even though no sale or disposal of shares is made.

Stamp Duty. There is no stamp duty payable for holding shares, and no duty is payable on the issue of new shares. Singapore stamp duty is payable on a transfer of existing shares if there is an instrument of transfer executed in Singapore or if there is an instrument of transfer executed outside Singapore that is received in Singapore. In such situations, stamp duty is payable on the instrument of transfer of such shares at the rate of 0.2% of the consideration for, or market value of, such shares, whichever is higher. The stamp duty is borne by the purchaser unless there is an agreement to the contrary. If the instrument of transfer is executed outside of Singapore, the stamp duty must be paid only if the instrument of transfer is received in Singapore.

Estate Taxation. Singapore estate duty was abolished for deaths occurring on or after February 15, 2008.

Tax Treaties Regarding Withholding. There is no reciprocal income tax treaty between the U.S. and Singapore regarding withholding taxes on dividends and capital gains.

You should read the following discussion and analysis of our financial condition and results of operations in conjunction with our consolidated financial statements and notes thereto included in Item 8, "Financial Statements and Supplementary Data." In addition to historical consolidated financial information, the following discussion and analysis contains forward-looking statements that involve risks, uncertainties, and assumptions. Our actual results could differ materially from those anticipated by these forward-looking statements as a result of many factors. We discuss factors that we believe could cause or contribute to these differences below and elsewhere in this report, including those set forth under Item 1A, "Risk Factors." Refer to Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations" contained in our Annual Report on Form 10-K for the fiscal year ended March 31, 2025, for the results of operations discussion for the fiscal year ended March 31, 2025, compared to the fiscal year ended March 31, 2024, other than as described below with respect to segment results from operations.

OVERVIEW

We are the advanced, end-to-end manufacturing partner of choice that helps a diverse customer base design, build, deliver and manage innovative products that improve the world. Through the collective strength of a global workforce across approximately 30 countries with responsible, sustainable operations, we deliver technology innovation, supply chain, and manufacturing solutions to diverse industries and end markets.

The Company’s full suite of specialized capabilities includes design and engineering, supply chain, manufacturing, and integrated services, plus a portfolio of power and cooling products. Over time, we have built differentiated scale and expertise across both technology-driven and regulated markets, enabling us to support customers with increasingly complex product, infrastructure, and compliance requirements. We partner with customers across a diverse set of industries including data center, healthcare, industrial, automotive, communications, and lifestyle.

In the fourth quarter of fiscal year 2026, the Company changed how it reports its operating results to its Chief Operating Decision Maker (“CODM”), principally reflecting the growth of Flex’s data center‑related businesses. As a result, the Company reorganized its operating structure and established a new operating and reportable segment, Cloud and Power Infrastructure (“CPI”) and updated its former segments from Flex Agility Solutions and Flex Reliability Solutions to Integrated Technology Solutions (“ITS”) and Regulated Manufacturing Solutions (“RMS”). Certain prior‑period segment information has been recast to conform to the current presentation. The determination of the separate operating and reportable segments is based on several factors, including the nature of products and services, the nature of production processes, customer base, delivery channels and similar economic characteristics. Refer to note 1 "Organization of the Company" to the consolidated financial statements in Item 8, "Financial Statements and Supplementary Data" for further details on the segment change that took place in the fourth quarter of fiscal year 2026.

As of March 31, 2026, we report our financial performance based on three operating and reportable segments as follows

• Integrated Technology Solutions ("ITS"), which is comprised of the following end markets:

◦Communications, high speed networking, enterprise, and satellite communications systems

◦Lifestyle, premium products across commercial, home and personal product categories

• Regulated Manufacturing Solutions ("RMS"), which is comprised of the following end markets:

◦Industrial, mission-critical automation, energy, and industrial infrastructure

◦Automotive, compute and power electronics platforms, and integrated systems

◦Healthcare, regulated manufacturing for medical devices, drug delivery and equipment

• Cloud and Power Infrastructure ("CPI"), which is comprised of the following end markets:

◦Cloud and Cooling, integrated compute systems supporting power‑dense digital infrastructure deployments, and advanced liquid cooling solutions supporting higher-density, power-intensive rack architectures

◦Power, utility and facility‑level electrical infrastructure enabling reliable, scalable power delivery and high-density rack- and board-level power systems supporting power-intensive compute workloads

In fiscal year 2025, we formally introduced the next phase in our strategic evolution, our EMS + Products + Services approach. This hybrid model is focused on strengthening our core manufacturing and supply chain capabilities while expanding

our portfolio of proprietary products and value-added services to maximize value creation for customers. To advance this approach, we completed several strategic acquisitions in fiscal year 2025 that enhanced our differentiated portfolio to address critical data center customer challenges around power, heat and scale. These included the acquisitions of JetCool to expand direct-to-chip liquid cooling capabilities and Crown to increase critical power capabilities while adding opportunities in grid modernization. We continued with the acquisition of a power facility in Poland in fiscal year 2026 and the acquisition of Electrical Power Products in May 2026.

Our strategy is to provide customers with a full range of cost competitive, vertically-integrated global supply chain solutions through which we can design, build, ship and service a complete packaged product for our customers. This enables our customers to leverage our supply chain solutions to meet their product requirements throughout the entire product lifecycle.

In today’s business landscape, we are witnessing greater product diversification by many companies, primarily in the technology sector, along with increased product complexity. These companies now require unique and customized manufacturing and supply chain solutions that meet their evolving requirements.

We use a portfolio approach to manage our extensive service offerings. As our customers change the way they go to market, we have the capability to reorganize and rebalance our business portfolio in order to align with our customers' needs and requirements in an effort to optimize operating results. The objective of our business model is to allow us to be flexible and redeploy and reposition our assets and resources as necessary to meet specific customers' supply chain solution needs across all the markets we serve and earn a return on our invested capital above the weighted average cost of that capital.

We believe that our strategy is positioning us to take advantage of the long-term, future growth prospects for outsourcing of advanced manufacturing capabilities, design and engineering services and after-market services.

We are continuously evaluating our capital structure in response to the current environment and expect that our current financial condition, including our liquidity sources are adequate to fund future commitments. See additional discussion in the Liquidity and Capital Resources section below.

Cloud and Power Infrastructure (CPI) Segment Spin-off

On May 5, 2026, we announced our intention to separate our CPI segment from Flex and into an independent, publicly traded company (“SpinCo”). The separation of CPI into SpinCo will create a separate publicly traded company focused on data center power, digital infrastructure and power, thermal and compute integration. The spin-off of CPI from Flex is expected to be completed in the first quarter of calendar 2027 and is subject to certain customary conditions, including, among others, the approval of Flex’s Board of Directors, shareholders, and the High Court of the Republic of Singapore and the SEC declaring SpinCo’s Form 10 registration statement effective.

INTEREST RATE RISK

A portion of our exposure to market risk for changes in interest rates relates to our highly liquid investment portfolio, with maturities of three months or less from original dates of purchase and are classified as cash equivalents on our consolidated balance sheet. We do not use derivative financial instruments in our highly liquid investment portfolio. We place cash and cash equivalents with various major financial institutions and highly rated money market accounts. Our investment policy has strict guidelines focusing on preservation of capital. The portfolio is comprised of various instruments including term deposits with banks, marketable securities and money market accounts. Our cash is principally invested in the U.S. dollar and China renminbi serving as a natural hedge of our renminbi denominated costs. As of March 31, 2026, the outstanding amount in the highly liquid investment portfolio was $1.6 billion, the largest components of which were U.S. dollar, Indian rupee, Brazilian real and Hong Kong dollar denominated money market accounts with an average return of 3.1%. A hypothetical 10% change in interest rates would not be expected to have a material effect on our financial position, results of operations and cash flows over the next fiscal year.

As of March 31, 2026, the approximate average fair value of our debt outstanding under our Notes due January 2028, June 2029, May 2030, January 2032, and November 2035 was 99.8% of the face value of the debt obligations based on broker trading prices in active markets.

FOREIGN CURRENCY EXCHANGE RISK

We transact business in various foreign countries and are, therefore, subject to risk of foreign currency exchange rate fluctuations. We have established a foreign currency risk management policy to manage this risk. To the extent possible, we manage our foreign currency exposure by evaluating and using non-financial techniques, such as currency of invoice, leading and lagging payments and receivables management. In addition, we may borrow in various foreign currencies and enter into short-term and long-term foreign currency derivative contracts, including forward, swap, and option contracts to hedge only those currency exposures associated with certain assets and liabilities, mainly accounts receivable, accounts payable, debt, and cash flows denominated in non-functional currencies.

We endeavor to maintain a partial or fully hedged position for certain transaction exposures. These exposures are primarily, but not limited to, revenues, customer and vendor payments and inter-company balances in currencies other than the functional currency of the operating entity. The credit risk of our foreign currency derivative contracts is minimized since all contracts are with large financial institutions and accordingly, fair value adjustments related to the credit risk of the counter-party financial institutions were not material. The gains and losses on foreign currency derivative contracts generally offset the losses and gains on the assets, liabilities and transactions hedged. The fair value of currency derivative contracts is reported on the balance sheet. The aggregate notional amount of outstanding contracts as of March 31, 2026 amounted to $7.5 billion and the recorded fair values of the associated assets and liabilities were not material to the Company's consolidated financial position. The majority of these foreign exchange contracts expire in less than three months. They will settle primarily in the Chinese renminbi, Euro, British pound, Malaysian ringgit, Mexican peso, Polish zloty, Hungarian Forint and U.S. dollar.

Based on our overall currency rate exposures as of March 31, 2026, including the derivative financial instruments intended to hedge the nonfunctional currency-denominated monetary assets and liabilities, a significant appreciation or depreciation of the U.S. dollar from its cross-functional rates would not be expected, in the aggregate, to have a material effect on our financial position or performance in the near-term.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Flex Ltd., Singapore

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Flex Ltd. and subsidiaries (the "Company") as of March 31, 2026 and 2025, the related consolidated statements of operations, comprehensive income, shareholders' equity, and cash flows for each of the three years in the period ended March 31, 2026, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of March 31, 2026 and 2025, and the results of its operations and its cash flows for each of the three years in the period ended March 31, 2026, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of March 31, 2026, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated May 20, 2026 expressed an unqualified opinion on the Company's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the 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 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 financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Revenue - Variable Consideration and Associated Customer-Related Accruals for Pricing Adjustments - Refer to Notes 2 and 4 to the Consolidated Financial Statements

Critical Audit Matter Description

Certain of the Company’s customer agreements include potential price adjustments which may result in variable consideration. These price adjustments include, but are not limited to, sharing of cost savings, committed price reductions, purchase price variances earned over the period that are contractually required to be paid to the customers, rebates, refunds tied to performance metrics such as on-time delivery, and other periodic pricing resets that may be refundable to customers. The Company estimates the variable consideration related to these price adjustments as part of the total transaction price and recognizes revenue in accordance with the pattern applicable to the performance obligation, subject to a constraint. The Company constrains the amount of revenue recognized for these contractual provisions based on its best estimate of the amount which will not result in a significant reversal of revenue in a future period. The Company determines the amounts to be recognized based on the amount of potential refunds required by the contract, historical experience and other surrounding facts and circumstances. These potential price adjustments are included as part of other current liabilities on the combined balance sheet and disclosed as part of customer-related accruals.

We identified the estimation of variable consideration and the associated customer-related accruals for pricing adjustments as a critical audit matter due to the judgments necessary to determine variable consideration and reassess the variable consideration in subsequent periods for pricing adjustments. This required extensive audit effort and a higher degree of auditor judgment when performing audit procedures to evaluate the reasonableness of the variable consideration and associated customer-related accruals for pricing adjustments.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to variable consideration and associated customer related accruals for pricing adjustments included the following, among others:

• We tested the effectiveness of controls the Company has in place relating to reviewing customer contracts to identify price adjustment clauses, estimating variable consideration and assessing the reasonableness of customer related accrual balances.

• We evaluated the Company’s accounting policy with respect to variable consideration, as well as its process for identifying contracts that include potential price adjustment clauses.

• We selected a sample of contracts with customers that included potential price adjustment clauses and performed the following:

–We read the customer contracts to develop an understanding of clauses that could give rise to variable consideration and evaluated whether the Company’s accounting conclusions with respect to those clauses were reasonable.

–We obtained and tested the mathematical accuracy of the Company’s calculations of customer related accruals and evaluated the Company’s judgments regarding the amount of variable consideration that should be deferred and the related adjustments recorded to customer-related accruals. In making this evaluation, we considered both the terms included in the customer contract and the Company’s historical experience in settling amounts with the customer.

The Company's management, with the participation of the Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the Company's disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) as of March 31, 2026. Based on that evaluation, the Company's Chief Executive Officer and Chief Financial Officer concluded that, as of March 31, 2026, the Company's disclosure controls and procedures were effective in ensuring that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act, is (i) recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms and (ii) accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

(b)Management's Annual Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13a-15(f) under the Exchange Act. Internal control over financial reporting consists of policies and procedures that: (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (2) are designed and operated to provide reasonable assurance regarding the reliability of the Company's financial reporting and the Company's process for the preparation of financial statements for external purposes 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 (3) 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 limitations, a system of internal control over financial reporting can provide only reasonable assurance and may not prevent or detect misstatements or prevent or detect instances of fraud. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls may be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The 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.

As of March 31, 2026, under the supervision and with the participation of management, including the Company's Chief Executive Officer and Chief Financial Officer, an evaluation was conducted of the effectiveness of the Company's internal control over financial reporting based on the framework in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"). Based on that evaluation, management concluded that the Company's internal control over financial reporting was effective as of March 31, 2026.

(c)Attestation Report of the Registered Public Accounting Firm

The effectiveness of the Company's internal control over financial reporting as of March 31, 2026 has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report which appears in this Item under the heading "Report of Independent Registered Public Accounting Firm."

(d)Changes in Internal Control Over Financial Reporting

To the shareholders and the Board of Directors of Flex Ltd., Singapore

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Flex Ltd. and subsidiaries (the "Company") as of March 31, 2026, 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 Company maintained, in all material respects, effective internal control over financial reporting as of March 31, 2026, based on criteria established in Internal Control—*Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended March 31, 2026, of the Company, and our report dated May 20, 2026 expressed an unqualified opinion on those financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

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 (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) 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 (3) 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 limitations, 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.
