Slide 3 — Letter from Dave Mosley, CEO

Letter from Dave Mosley, CEO OUR VALUES: INTEGRITY, INNOVATION, INCLUSION We recognize that businesses have the power and opportunity to make a difference in our world. We are a leader in sustainable and responsible practices to support our commitment to global corporate citizenship. We collaborate with key stakeholders and partners to achieve this shared vision. We live these commitments through our Value of Integrity. As a global hardware, software, and services company, Seagate understands our responsibility to lead by example and do good while doing well. Acting on our values of Integrity, Innovation, and Inclusion, we strive to advance sustainable solutions that transparently address critical environmental and social priorities. I am honored to present our Fiscal Year 2021 Global Citizenship Annual Report, and share the progress we continue to make towards advancing a more Sustainable Datasphere. Seagate recognizes the gravity of climate change’s impact on the planet, and we remain committed to reducing our global carbon footprint. We are actively collaborating with industry peers and thought leaders to drive the innovation necessary to achieve that objective. Seagate commits to transparency with our stakeholders by being accountable to the United Nation’s Sustainable Development Goals (SDGs), Science-Based Targets (SBTs), Global Reporting Initiative (GRI) standards, and the Sustainability Accounting Standards Board (SASB) standards. These commitments are critical in helping Seagate target meaningful metrics relevant to the pressing issues affecting the world. At Seagate, we seek to build circularity into every product and service that we release to the data market. We are applying our scale and influence to mobilize our customers, supply chain partners, and other technology companies to aid in this effort. We are modeling data storage’s impact on global warming and focusing on sourcing materials that address finite natural resources and their use, reuse, and substitution in our products. We are partnering with customers to advance our products’ secure erase, refurbish and reuse technologies. The COVID-19 pandemic requires that we innovate our working methodologies within Seagate to best serve our customers. Our teams have sustained Seagate’s operations by adhering to safety protocols. They have also found novel solutions for challenges within our global supply chain and manufacturing operations. I take deep pride in the actions our suppliers and employees have taken together to ensure life safety, sustain business operations, and demonstrate our values of Integrity, Innovation, and Inclusion through this crisis. We are continuing to elevate our business and industry by acting on our value of Inclusion. Gender and racial equity remain an important part of Seagate’s people-related policies and diversity, equity, and inclusion programs. Leaders at Seagate support these programs by endeavoring to ensure that all employees have a safe and professional work environment as well as opportunities for professional growth. Seagate is a founding member of the Responsible Business Alliance (RBA) and a strong supporter of the United Nations Global Compact (UNGC). As such, we believe that all people are entitled to fundamental rights and freedoms. We strive to meet the highest standards of ethical conduct and to maintain strict systems and processes to ensure fair and ethical working conditions.  We commit to being both a global citizenship leader and advocate, transparent in our efforts and continually striving for improvement. In FY2022, we will be incorporating aspects of this commitment into our executives’ long-term compensation plans, based on the achievement of certain quantitative environmental (greenhouse gas reduction) and social (gender diversity) targets. Our values of Integrity, Innovation, and Inclusion inspire our global Seagate team, establish our priorities, underpin our decision making, and guide us in meaningful engagement with our stakeholders. As we look to FY2022 and the future, we will expand our reach and impact of these priorities. Thank you for partnering with Seagate on our journey toward a Sustainable Datasphere. 4 FY2021 Global Citizenship Annual Report FY2021 Global Citizenship Annual Report 5

Slide 4 — GLOBAL CITIZENSHIP HIGHLIGHTS

GLOBAL CITIZENSHIP HIGHLIGHTS GLOBAL CITIZENSHIP HIGHLIGHTS Seagate is proud to continue our decades-long tradition of sharing our environmental, social and governance (ESG) priorities, goals, and year-over- year accomplishments. However, we do not limit our definition of success to our efforts alone; we recognize Seagate can affect change at-scale and on a global level by being closely engaged with industry peers, customers, supply chain partners, governments around the world, and civil society. We believe we will make an exponential impact by working collectively toward common goals with these and other entities. In FY2021, Seagate continued our leadership role in the Responsible Business Alliance (RBA): Seagate’s Senior Vice President of Business Sustainability and Transformation served as Chair of the Board and Executive Committee. In addition, Seagate employees lead and participate in the Assessments Workgroup, as well as other RBA workgroups. Seagate also continued our partnership with industry organizations including the Clean Electronics Production Network (CEPN), the Responsible Minerals Initiative (RMI), IPC International Inc., and the International Electrotechnical Commission (IEC). All of these engagements help to advance sustainability efforts in the industry at a global scale. To achieve our goals, we commit to continuous improvement and aligning to key standards provided by the International Organization for Standardization (ISO). We comply with the Global Reporting Initiative (GRI) and the Sustainability Accounting Standards Board (SASB) standards, while targeting compliance with the Task Force on Climate-Related Financial Disclosures (TCFD) standards. The following section reflects highlights of our efforts over the past fiscal year.

Slide 6 — Climate and Energy

GLOBAL CITIZENSHIP HIGHLIGHTS GLOBAL CITIZENSHIP HIGHLIGHTS Seagate aligns with ISO standards as we implement and improve energy management systems. In FY2021, we received ISO 50001 Energy Management System certification for all seven of our manufacturing sites. Our Scope 1 and Scope 2 market-based GHG (greenhouse gas) emission intensity per EB (Exabyte) was reduced to approximately 2,494 tCO2e/EB (Tons of Carbon Dioxide Equivalent per Exabyte) in CY2020, compared to 3,156 tCO2e/EB in CY2019. Seagate is making progress towards meeting Science- Based Targets, validated by Science Based Targets initiative (SBTi) in CY2019; our CY2017 baseline has been adjusted with the latest emission factors and assumptions in response to data availability, structural and methodological changes or updates. Seagate recognizes that water is a critical natural resource, and we actively manage how water is used in our manufacturing processes and at our sites worldwide. An important aspect of Seagate’s water stewardship strategy is implementing innovative approaches to the treatment and disposal of wastewater from our manufacturing sites. Seagate has been named to CDP’s Climate A List 2020, highlighting our leadership in managing for climate change and working towards reduced GHG emissions. We also received an A- in Water Security and were ranked as a Supplier Engagement Leader. More information on our climate change and water stewardship efforts and results can be found in Seagate’s CDP Climate Change Disclosure and CDP Water Security Disclosure. Guided by our value of Innovation, Seagate is minimizing product impact by improving product quality and extending the useful life of our products. In FY2021, we continued our strategic partnership with Dell Technologies, completing a closed-loop aluminum recycling program that produced 24.7K new BarraCuda 3.5 2TB (Terabyte) drives from recycled material and recycled 39.4 metric tons of aluminum scrap. Seagate also continued collaboration with Google that began in FY2020 on a circular component pilot in which the Voice Coil Magnet Assemblies (VCMAs) were successfully recovered from several thousand end-of-use Hard Disk Drives (HDDs) and reused in closed-loop manufacturing of new HDDs. In FY2021, a Life Cycle Assessment (LCA) analysis was conducted on an enhanced version of the process for recovery and closed-loop reuse of VCMA’s. The LCA analysis also confirmed an 86 percent reduction in GHG emissions per VCMA set in the new drives as compared to the manufacture of a VCMA set from the linear extraction-manufacture process. Seagate commits to meet or exceed restricted substance standards by adhering to global restricted substance legislation. This includes European Regulation (EC) 1907/2006 concerning the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) and the Directive of the European Parliament and of the Council on the Restriction of the Use of Certain Hazardous Substances (RoHS) in Electrical and Electronic Equipment 2011/65/EU (RoHS) and amended by 2015/863/EU, among others. For FY2021, Seagate is now registered with the European Chemical Agency’s (ECHAs) new public database of Substances of very high Concern in Products (SCIP). The SCIP database ensures that information on articles (articles are parts or subparts in an assembly that make up a finished product) containing Candidate List substances are available throughout the whole lifecycle of our products.

Slide 8 — GLOBAL CITIZENSHIP HIGHLIGHTS

GLOBAL CITIZENSHIP HIGHLIGHTS GLOBAL CITIZENSHIP HIGHLIGHTS Diversity, Equity, and Inclusion In FY2021, Seagate remained focused on building diverse talent pipelines through partnerships with minority engineering organizations and expanded our reach to the United States military and veteran communities. We continued to enhance our diversity training and education resources by increasing participation in our LGBTQ+ (Lesbian, Gay, Bisexual, Transgender, and Queer) Ally Training and our Neurodiversity 101 digital training. We continued our global unconscious bias program, including live and virtual workshops. Engaging with McKinsey’s Black Leadership Academy provided employees an opportunity to connect with industry peers and business leaders. We also joined PricewaterhouseCoopers’ CEO Action for Racial Equity Fellowship, mobilizing diverse talent and expertise from across industries. Seagate’s Diversity, Equity, and Inclusion report for FY2021 can be found here. Employee Development, Engagement and Retention Seagate works to foster an environment that inspires and supports employee performance through rich conversations and coaching, continuous learning and development, and collaboration. We successfully launched our Leadership Essentials Program with the objective of equipping our leaders with the tools to foster employee growth. Employee Health and Safety The COVID-19 pandemic has shown us that Environment, Health, and Safety (EHS) reaches beyond traditional workplace health and safety. Seagate remains committed to our enhanced site controls to ensure the health and safety of our workforce while ensuring continuity of our business operations. Health and safety measures such as physical distancing, temperature and health screenings, masking Business Continuity Seagate is committed to investing in and protecting our operations and community from the many potential risks and threats that could affect our business. Throughout FY2021, we continued to mature our Business Continuity Management System (BCMS). This enabled effective management and mitigation of the various risks and threats to our business. Our BCMS encompasses four pillars of planning: requirements, increased cleaning and disinfection, and contract tracing measures remain in place and are frequently assessed for their effectiveness. Community Engagement Seagate’s local programs support our communities and focus on Science, Technology, Engineering, and Mathematics (STEM). In FY2021, we reached a large audience and provided meaningful impact by partnering with Seagate employees, local community members, nonprofit partners, civic and academic institutions, and governments. Supply Chain Due Diligence We view our supply chain as an extension of our footprint. We have a responsibility to conduct due diligence to ensure our business partners manage their operations in a suitable way. Seagate has adopted the RBA Code of Conduct as our supplier code of conduct and expects our suppliers to manage their business in accordance with the RBA Code. Business Continuity Planning Incident Management Crisis Management Supply Chain Risk Management In CY2020, our manufacturing sites in China and Thailand were audited and maintained their ISO 22301:2012 certifications. In FY2021, Seagate continued to execute our global response to the dynamic COVID-19 pandemic. Our mature enterprise-wide crisis management structure, with input from site leaders, mitigated risk where possible and determined critical courses of action. These measures enabled the continuity of business operations. As health and safety remained our priority, the increased vaccine availability globally and the rollout of Seagate onsite vaccination clinics to our employees ensured another layer of protection from the impacts of COVID-19. 1 2 3 4 14 FY2021 Global Citizenship Annual Report FY2021 Global Citizenship Annual Report 15

Slide 11 — Management Approach

ABOUT THIS REPORT ABOUT THIS REPORT SENIOR MANAGEMENT WHO REPORT TO THE CEO Seagate maintains a structure of governance and continuous improvement through the implementation of Business Process Management (BPM) spanning all functional and value creation processes across our enterprise. Leveraging the structures and hierarchy of BPM, we develop and periodically review management documentation in Corporate Standard Operating Procedures (CSOP), processes, and work instructions for relevance, quality, and compliance. To ensure cross- functional alignment, we define, evaluate, and improve End to End Value Stream Processes on an ongoing basis. Seagate also continues to follow the ISO standards to ensure compliance with standards and a commitment to continuous improvement. Our performance metrics measure the effectiveness of the BPM program and ISO compliance in delivering intended results. Through Seagate’s internal audit program, we ensure that this management approach, processes, measurements, and controls are operating effectively in managing the risk and opportunities. Based on the performance metrics and internal audit results, we take actions to improve the programs. Economic, environmental, governance, and social programs are managed by the relevant functional departments, with oversight by senior management who report directly to the CEO. These include, but are not limited to, our Senior Vice President, Business Sustainability and Transformation; Senior Vice President and Chief Human Resource Officer; Senior Vice President, Chief Legal Officer; and the Executive Vice President of Operations and Technology.

This report has been prepared in accordance with the GRI Standards: Core option. In addition to following GRI Standards, this report also contains disclosures in accordance with the SASB, and certain TCFD standards. A list of the indicators and their locations can be found in the Content Indexes at the end of this report. Additionally, as noted in last year’s report, in FY2020, Seagate engaged a third-party to conduct a sustainability materiality assessment to identify, prioritize, and validate the aspects that are most significant to our business and our stakeholders. The assessment covered reviewing industry standards and external trends covering ESG topic areas. It also included speaking with both internal and external stakeholders to develop a comprehensive understanding of Seagate’s significant impacts, where those impacts occur, and how various issues may influence the assessments and decisions of stakeholders. No aspect was intentionally excluded from the scope of the assessment. The topics identified as material to our business are categorized into governance and ethics, product security and data privacy, product stewardship, environmental sustainability, our employees, supplier engagement, community engagement, and business continuity. These topics, along with stakeholder feedback gathered during the materiality assessment helped shape the content and structure of this report. We review our sustainability materiality assessment annually. After our review in FY2021, we concluded that the assessment from FY2020 remained valid. We will continue to review business operations each year and conduct sustainability materiality assessments as needed. A breakout of findings and their sub-topics as well as policies that drive our commitment and compliance can be found here. Defining Report Content Seagate’s FY2020 Global Citizenship Annual Report (GCAR) inadvertently included one error in the measurement units for Water Intensity Decreased. Liters per EB was the measurement referenced. The correct measurement was megaliters per EB. This error and its correction are relevant to the FY2020 GCAR, pages 15 and 56.

Slide 14 — COMPLIANCE AND ETHICS, AND CORPORATE GOVERNANCE

COMPLIANCE AND ETHICS, AND CORPORATE GOVERNANCE COMPLIANCE AND ETHICS, AND CORPORATE GOVERNANCE Compliance and Ethics, and Corporate Governance Seagate’s Code of Conduct serves as a guide for demonstrating Integrity and conducting ourselves legally and ethically every day and in every location where we conduct business. 04 Seagate’s Code of Conduct is supplemented by our Code of Ethics for Senior Financial Officers, both of which are publicly available on our website. We periodically evaluate and assess our Code of Conduct and related policies, programs, and processes for effectiveness and compliance with new laws and regulations.  Our Code of Conduct helps ensure a principles-based approach to our business activities. It summarizes Seagate’s ethical standards and key policies across areas such as insider trading, conflicts of interest, anti-bribery and anti-corruption, privacy, confidentiality, anti-harassment and anti- discrimination, and antitrust and fair dealing. To promote awareness and understanding of the Code of Conduct, we make it available in the following eight languages: Chinese, English, French, Korean, Malay, Portuguese, Spanish, and Thai. Training on our Code of Conduct is provided annually to all non-operator employees and all new non-operator employees must promptly complete it when hired. The training is available in Chinese, English, French, Korean, Malay, Spanish, and Thai. We target 100 percent completion rate of these key compliance trainings.  Through Seagate’s global Compliance and Ethics program (C&E Program), we have a centralized and coordinated approach to ensuring that there is a comprehensive system of policies, processes, and standards that prevent, detect, and correct violations of laws, regulations, and corporate policies. Our C&E Program reflects internationally accepted hallmarks of an effective compliance program, and we take a strategic, risk-based approach relevant to Seagate and our employees.  Seagate brings leaders from all key business functions together in our Global Compliance and Ethics Council (GCEC) to align with the C&E strategy, policies, and procedures. The GCEC was established in FY2021 and has geographic and operational reach throughout Seagate.   Compliance and Ethics 26 FY2021 Global Citizenship Annual Report FY2021 Global Citizenship Annual Report 27

Slide 15 — Corporate Governance

COMPLIANCE AND ETHICS, AND CORPORATE GOVERNANCE COMPLIANCE AND ETHICS, AND CORPORATE GOVERNANCE The C&E Program is further strengthened through deliberate cross-functional collaboration and consistent integration with key functional areas such as Human Resources, Business Sustainability and Transformation, Finance, and Sales. Through these partnerships, we continually build upon and enable a culture focused on a variety of areas of importance such as sustainability, and diversity, equity, and inclusion.   Our C&E Program focuses on key risk areas, which are assessed on an ongoing basis. Our Anti-Bribery and Anti-Corruption Policy requires all Seagate Board members, officers, employees, business partners, and suppliers to follow all applicable laws and regulations, including the United States Foreign Corrupt Practices Act and the United Kingdom Bribery Act. We provide training and awareness to employees as well as key business partners and customers on Seagate’s expectations in key areas such as anti-bribery, anti- corruption, antitrust, and fair competition.  Seagate conducts an ethics risk assessment bi-annually at our manufacturing sites against the Ethics section of the RBA Code of Conduct, which corresponds with Seagate’s Code of Conduct. In FY2021, there were no significant risks of corruption or non-compliance identified through any ethics risk assessment among our seven manufacturing sites, which together comprise more than 86.6 percent of our global workforce.   Seagate’s Code of Conduct, C&E Program, policies, processes, standards and values of Integrity, Innovation and Inclusion set the tone and framework for a strong culture of compliance and ethical conduct at Seagate. By working together, we empower our employees to act with integrity. Seagate is governed by its Board of Directors and has adopted Corporate Governance Guidelines to clarify how it exercise its responsibilities. These guidelines demonstrate that the Board has the necessary authority and practices in place to review and evaluate Seagate’s business operations and make decisions independently of company management.

Slide 16 — Product Security

COMPLIANCE AND ETHICS, AND CORPORATE GOVERNANCE COMPLIANCE AND ETHICS, AND CORPORATE GOVERNANCE Product security is at the forefront in our continual commitment to Integrity. As data becomes a larger contributor to the world’s quality of life, both its value and risk grow, increasing the need for data protection. Safeguarding our products and the data they house can only be achieved through a holistic approach to secure best practices at every phase of the product lifecycle. With rigorous product testing and the implementation of innovative security features such as Instant Secure Erase (ISE), this multi-layered mitigation strategy offers an unequalled level of protection for businesses, governments, and individual consumers. Seagate’s Product Security Office assures integrity in information systems using a structured process. Information systems that are critical to the integrity of the products’ security are routinely validated to comply with Seagate’s corporate IT policy and to meet ISO 20243 supply chain product security requirements. Product lines become ISO 20243 certified through a formal assessment by a third-party accredited laboratory. We identify data security risks and vulnerabilities within products through a Product Security Test and Evaluation process. This includes performing security reviews to assess controls, architecture, and design, and to gauge cyber resilience via code scanning and penetration testing. Mitigation and/ or remediation of the findings is governed via the controls in Seagate’s gated product development process to assure closure prior to release. Global supply chains are vital to our business, and the security of our partners both upstream and downstream underlies our collective success. Minimizing the risks that affect both Seagate and our partners requires that we extend security to every stage, from product development and manufacturing to sourcing and delivery. We have implemented comprehensive product lifecycle standards and frameworks, including ISO certifications, to create safeguards for our business and our supply chain. The integrity of global supply chains is more important than ever in our increasingly interconnected world. Minimizing risk requires aligning priorities among our sites, our critical suppliers, and our partners. With product life cycle standards and frameworks, including ISO certification, Seagate has established a uniform baseline of safeguards at every stage, including product development, sourcing, and manufacturing – key elements that provide comprehensive supply chain security. Product Security Seagate deploys product security and privacy preservation measures by integrating security features on the drive itself, along with a trusted chain of custody in the reverse supply chain. This enables a circular economy of trusted technology that increases sustainability through the reuse, repair, and resale of products that would otherwise generate e-waste. These methods support our goal to increase the quantity of drives each year that re-enter circulation. More information on product security can be found on our website here. 30 FY2021 Global Citizenship Annual Report FY2021 Global Citizenship Annual Report 31

Slide 18 — PRODUCT SUSTAINABILIT Y

PRODUCT SUSTAINABILIT Y PRODUCT SUSTAINABILIT Y Seagate takes a holistic view of how our products affect the environment and our communities, and works with an industry collective of our customers, suppliers, and peers to address that impact. Product Sustainability Our stakeholders specifically identified material use and circularity as topics of high interest in our sustainability materiality framework assessment. Our overarching goal for Seagate’s Product Sustainability is to maximize our sustainable practices and minimize our impacts. This also enables Seagate to support our customers and suppliers to meet their own environmental objectives. The Product Sustainability team, and Seagate as a whole, recognize that we are responsible for the environmental impact of the products we place in the market. Seagate’s products use process chemicals and materials drawn from natural resources. This results in impacts that our internal policies and procedures, which range from material restrictions to responsible sourcing of material, are designed to mitigate. Our Product Sustainability team works with internal and external partners to assess and reduce the effect our products have on the environment and conducts LCAs and other analyses to help manage any tradeoffs. We evaluate the management system through various channels including management reviews, LCAs, internal and external verifications, and audits and performance against targets. We believe the management system is functioning effectively year over year, and minor adjustments are made as needed. Seagate publishes our progress on the Global Citizenship page of our website. Health and Safety considerations are addressed at the design stage to meet all regulatory and customer requirements. For more information on our supply chain ESG Program, please refer to the supply chain section of this report. 05 All of Seagate’s products are assessed to meet regulatory requirements for health and safety in jurisdictions where we do business. In FY2021 we had zero incidents of non- compliance with such regulations. Additionally, none of Seagate’s products or services are banned in any markets where we do business. A global cross-functional team, known as our Global Market Access Council, is chartered with ensuring all regulatory requirements are met when placing our products in the markets where we do business. 34 FY2021 Global Citizenship Annual Report FY2021 Global Citizenship Annual Report 35

PRODUCT SUSTAINABILIT Y PRODUCT SUSTAINABILIT Y Our Corporate Sustainability organization maintains Full Material Disclosures (FMD) from our suppliers for each part included in our products; we require our suppliers to refresh this annually. FMDs list the materials and substances that are in components to determine how much energy, water and material is used to produce the components, as well as to determine human toxicity. This information is used in our product LCAs to target improvements to our products’ environmental impact and can be accessed quickly to address any concerns about substances that arise. Our LCAs are conducted in accordance with the International Organization for Standardization (ISO) 14040:2006 and 14044:2006. The Seagate Green Design Tool, based on Footprinter™ models, is used to help create the LCAs, and has achieved a limited assurance verification by UL Environment based on criteria as detailed in the International Standards for LCA (ISO 14040 and ISO 14044), and the World Resources Institute (WRI) and World Business Council for Sustainable Development (WBCSD) Greenhouse Gas Protocol Product Life Cycle Accounting and Reporting Standard.

Slide 20 — Response

PRODUCT SUSTAINABILIT Y PRODUCT SUSTAINABILIT Y We prioritize product LCAs based on production volume and customer data requirements. We assess 100 percent of our products for health and safety, and improvements related to health and safety, based on a representative drive from each family of products. Product-related Health and Safety risks are addressed in the design of our products and are provided in product manuals to users. With our commitment to credibility and transparency, we maintain third-party assurance for the complete reporting of LCA results. The actual use of our products represents the most significant environmental impact of the product life cycle. We believe the single largest opportunity to reduce the environmental impacts from our products use is the proper application of Seagate’s product power conservation modes. This enables customers to both reduce the costs associated with drive operation and lower the impacts to the environment without sacrificing performance. The advantages of these power conservation modes are described in the product manuals. Seagate does not stipulate post-consumer content when procuring components or parts from suppliers; however, we acknowledge that there is post-consumer material inherent in today’s raw material supply. Utilizing data from our LCAs, Seagate is able to determine the impact of metal depletion per TB of storage capacity shipped on average for our product portfolio. The metal depletion indicator specifies the amount of mineral deposits that are consumed to provide the end-use material in question. The process is normalized to the extraction of iron (kg Fe-Eq). More than 90 percent of our product is made from minerals; for CY2020, the average metal depletion per TB across Seagate’s product portfolio was 2.50 kg Fe-Eq, and the total impact to metal depletion equates to approximately 1.3 million metric tons of Fe-Eq. The material is non- renewable and is limited to the production of the product only. The information disclosed does not include packaging. Our LCA reports are published on Seagate’s external website, and cover our Enterprise HDD, Enterprise SSD and Consumer HDD products. Product Life Cycle Management SASB Information * The EPEAT standard does not apply to our product portfolio, however we do provide data in support of our customers who submit their systems for EPEAT registration. ** Seagate customers are responsible for end-of-life e-waste management according to local requirements.

Slide 21 — Packaging

PRODUCT SUSTAINABILIT Y PRODUCT SUSTAINABILIT Y As documented in the FY2020 report, Seagate and Google collaborated on a circular component pilot in which the VCMAs were successfully recovered from several thousand end-of-use HDDs and reused in closed-loop manufacturing of new HDDs. In FY2021, an LCA analysis was conducted on an enhanced version of the process for recovery and closed-loop reuse of VCMA’s. The LCA analysis confirmed an 86 percent reduction in GHG emissions per VCMA set in the new drives as compared to the manufacture of a VCMA set from the linear extraction-manufacture process. CIRCULARITY PILOT We are continuously working to reduce our packaging volume and impact while meeting product requirements. Packaging is relevant to both our environmental impact and our stakeholder goals. As Seagate and our customers move towards reducing the use of single-use plastics, we continue to work holistically to reduce packaging and recycle as much of our packing material as possible. In FY2021, all core Seagate HDD products were shipped using certified Forest Stewardship Council (FSC) packaging, which constitutes approximately 3,567 metric tons of paper material. As of FY2021, all packaging for Seagate Consumer Solutions Group products is made from 100 percent recycled plastic, which is also 100 percent recyclable. All paper boxes (except retail boxes) are manufactured with 100 percent recycled materials. Currently, the retail box color scheme requirements prevent it from being sourced from recycled materials. Our LaCie products’ casing is made from recycled metals. There is increased attention on the circular economy as most industrialized countries recognize that linear (or “take-make-waste”) economies are unsustainable for both their businesses and our global wellbeing. This is driven in part by growing recognition of the reality of dwindling finite resources and increasing concerns regarding availability and access. Seagate is committed to pioneering innovation in circularity, both internally and with our external stakeholders and peers. Seagate includes a circularity metric within each product LCA, the Material Circularity Indicator (MCI). We created and maintain the MCI to benchmark our products, identify opportunities for improvement, and to target increased material efficiencies that benefit Seagate, our customers, and our partners. Our LCAs are publicly available on the Global Citizenship page of our website, for each product on which Seagate has completed ISO 14040/14044 LCA studies. Packaging Materials Use and Circularity Repair Keeping products in use longer Resale Sanitize, recertify and sell Refurbishing Buying back products and recertifying them as new Parts Extraction Reusing components Materials Recovery Recycling materials for reuse Distribution Materials or Energy Recovered Sustainable Production Individual Parts Raw Materials User LINEAR PRODUCTION MODEL Circular Production Model Waste In a circular economy, products that have reached the end of their life and would otherwise be destined for waste are diverted through the hierarchy of: The circular economy will affect the evolution of business models as well, shifting from the current make and ship paradigm to services that bookend the life cycle of products. Because most of Seagate’s products are sold as components to larger systems managed and produced by OEMs or resellers, we have limited leverage over how our products are managed at the end of their useful life. Just as we recycle our own internally generated scrap, we provide information to enable our customers’ reclamation efforts and encourage participation in manufacturer take-back programs. Seagate helps to manage product waste for our retail products and servers by taking back warranty-returned drives, extending the life of 1.29 million HDDs and SSDs in FY2021. The drives were recovered and placed back into the market, avoiding over 600 metric tons of e-waste. Drives are recycled at locations that have been audited by a third-party to ensure our environmental standards are met. We also provide customers with drive disassembly instructions to facilitate recycling. 40 FY2021 Global Citizenship Annual Report FY2021 Global Citizenship Annual Report 41

Slide 22 — FY2021 Circularity Program Indicators

PRODUCT SUSTAINABILIT Y PRODUCT SUSTAINABILIT Y LOOKING FORWARD: PRODUCT SUSTAINABILITY In FY2022, Seagate will continue pioneering innovation projects coupled with strong industry collaboration to achieve product sustainability improvements. Leveraging LCA metrics from both future and existing products, we intend to extend opportunities to reuse, refurbish, recover, and reclaim our products, components, and materials. LCAs will track the impact of these efforts, enabling circular economy with our customers and supply chain partners. In FY2022, Seagate will begin to transition from using Expanded Polypropylene (EPP) pink antistatic foam to EPP white non-antistatic foam to increase recyclability of our shipping and packaging containers. Seagate plans to provide a product take-back program for our customers to return drives to Seagate for refurbishment and reuse. By leveraging our effective product security features and processes and proven high yields in the recovery of HDDs, Seagate is poised to partner with our customers for extended use of our products. These specific actions, along with scaled implementation of all recycling and circularity opportunities in our design, source, and manufacture processes, will enable Seagate to extend our materials efficiency and circularity for the benefit of our stakeholders and the planet. FY2021 Circularity Program Indicators CASE STUDY The Strategic Partnership with Dell Technologies Continues in FY2021 We successfully completed the closed-loop aluminum recycling pilot program begun with Dell Technologies in FY2020. In the pilot, the HDD scrap motor base assemblies and aluminum discs from end-of-life drives were channeled to our base plate aluminum smelter for recycling. This pilot has since been adopted as an ongoing process and has produced 24.7k new BarraCuda 3.5 2TB V11X drives from the recycled material, resulting in 39.4 metric tons of aluminum scrap recycled. We continue our partnership on rare earth magnet recovery as well, with 1.1 metric tons of rare earth materials recovered, a step forward in reducing environmental impact. • 1.29 million HDDs and SSDs • Scrap Magnets: 1.1 metric tons • Scrap Aluminum: 39.4 metric tons Extending Product Life Material Recycling 42 FY2021 Global Citizenship Annual Report FY2021 Global Citizenship Annual Report 43

PRODUCT SUSTAINABILIT Y PRODUCT SUSTAINABILIT Y Restricted substances have a negative impact on the environment and human health, especially at the product end of life. Seagate’s target is to meet or exceed applicable global regulations and our customers’ strictest specifications for restricted substances. We compile customer and regulatory requirements into an overall Seagate restricted substance specification in an internal compliance database. Seagate has developed and communicated policies and procedures within the company and to our supply chain to ensure product environmental requirements are met. The restricted substances program is managed through Seagate’s product environmental compliance function. This function currently verifies supplier part restricted substance compliance for more than 3,000 declarable and restricted substances in our Compliance Assurance System (CAS). The Chemical Abstract Service numbers for chemical substances present in Seagate components and products are cataloged in the system as well. The information from our CAS database is used to respond to customer product environmental compliance inquiries; in FY2021 we received and responded to approximately 4,500 inquiries. Seagate strives to comply with all regulatory requirements where we and our customers do business; therefore, we adhere to global restricted substance legislation, including: • Directive of the European Parliament and of the Council on the Restriction of the Use of Certain Hazardous Substances (RoHS) in Electrical and Electronic Equipment 2011/65/EU (RoHS) and amendments including 2015/863/EU • The European Regulation (EC) 1907/2006 concerning the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) • Directive of the European Parliament and of the Council on Waste Electrical and Electronic Equipment (WEEE), 2002/96/EC and recast in 2012/19/EU  • United States Toxic Substances Control Act (TCSA), as amended in 2016 by the Frank R.

Slide 24 — Regulatory Compliance

PRODUCT SUSTAINABILIT Y PRODUCT SUSTAINABILIT Y Our restricted list of chemical substances is continuously updated. Seagate monitors regulatory, industry, and customer requirements for changes in order to comply with new reporting requirements and restrictions, including elimination from Seagate products if necessary. In FY2021, ECHA added 10 new substances to the REACH Candidate List of Substances of Very High Concern (SVHC), bringing the total number to 219 as of July 2021. Using FMD information from our CAS database, Seagate determines if and where SVHCs are present in our products, and at what concentrations, both at the homogeneous material and article levels. The 10 added substances were confirmed to not be present in any Seagate products or components. Updated REACH Article 33(1) declarations were generated and made available as an assurance to customers that the declarations account for all 219 SVHCs if present at >0.1 percent w/w (weight by weight) in articles (parts or subparts in an assembly the make up a finished product). Commencing January 5, 2021, Seagate began submitting information on articles in our products containing SVHCs at a concentration >0.1 percent w/w to ECHA’s new public SCIP database established under the Waste Framework Directive (2008/98/EC). Unique SCIP notifications are created for all Seagate products that contain SVHCs >0.1 percent w/w at the article level, with the information on Candidate List substances available throughout the entire life cycle of products, including to businesses, customers and recyclers at product end-of-life. Seagate products rely on certain RoHS 2011/EU Annex III exemptions for lead that were scheduled to expire in July 2021. Seagate supported renewal requests that were submitted by industry umbrella groups for essential uses of materials with lead >0.1% w/w where no suitable alternatives exist. These are under review at the time of this publication. Seagate continuously works with our suppliers to determine if there are suitable lead-free alternative materials, and where possible substitutions are made.

Slide 25 — Responsible Sourcing of Minerals

PRODUCT SUSTAINABILIT Y PRODUCT SUSTAINABILIT Y With the goal of exceeding product environmental compliance requirements, we try to enable customers to manage their own product compliance at the finished product level. This provides them with the opportunity to participate in programs such as the Electronic Product Environmental Assessment Tool (EPEAT). Seagate products are generally components, for which no EPEAT standards apply. Our ability to verify RoHS compliance and identify product composition at both the homogeneous material and article levels assures customers that the incorporation of Seagate components into their final products support their ability to meet both relevant EPEAT requirements and optional criteria. In FY2021, Seagate received no significant fines or nonmonetary sanctions for product environmental non-compliance, including those related to restricted substances. Working with our product environmental compliance business process outsourcing partner, we continue to identify and leverage process efficiencies. LOOKING FORWARD: RESTRICTED SUBSTANCES In FY2022, Seagate will continue to research, identify, and qualify suitable alternatives to hazardous substances in our products, including those components containing materials with RoHS exemptions, REACH SVHCs, and substances identified for potential future restriction. Seagate will also improve our awareness of substances used in current and future products to progress ahead of increased global regulatory restrictions, including increased restriction and reporting requirements in the United States, European Union, and other regions. The challenge remains in electronics industries of ensuring that conflict-free minerals are sourced in ways verified to be free from human rights abuses. Seagate remains committed and vigilant against human rights violations through our supply chain, and we continue our goal of maintaining a conflict-free status across our product portfolio. This effort begins with Seagate’s Responsible Sourcing of Minerals Policy, which covers all direct components that source into our product portfolio. Tin, tantalum, tungsten, gold (collectively, 3TG) and cobalt are minerals commonly mined in the Democratic Republic of the Congo (DRC) and adjoining countries, as well as other Conflict-Affected and High- Risk Areas (CAHRAs). Some of these minerals are prone to be illegally sourced and traded by armed groups who are responsible for human rights violations. The Dodd-Frank Act, Section 1502, adopted in the United States in CY2010, requires companies to investigate their mineral supply chains and disclose if any 3TG used in their products originated in the DRC or an CAHRAs. If so, efforts are required to be undertaken by the company to ensure the origins of these minerals are documented, identified, and and reported to the United States SEC.

Slide 26 — PRODUCT SUSTAINABILIT Y

PRODUCT SUSTAINABILIT Y PRODUCT SUSTAINABILIT Y Seagate participates in the Responsible Minerals Initiative (RMI), enabling us to contribute to industry solutions while maintaining standard processes for data collection and complying with regulations. Apart from a few instances, Seagate does not source any of the 3TG in our products directly from smelters/refiners. Seagate conducts mineral due diligence in alignment with the most recent version of the Organization of Economic Cooperation and Development (OECD) Due Diligence Guidance for responsible Supply Chains of Minerals from CAHRAs. Our Responsible Sourcing of Minerals Policy was reviewed and updated in CY2020 and is available on our website. We conduct training for our suppliers to raise awareness of our policy to maintain a responsible supply chain. During the training, Seagate advocates that the minerals used to produce our products are to be sourced from smelters and refiners validated as Conformant to the Responsible Minerals Assurance Process standards. Seagate requires our suppliers to conduct annual due diligence and report sourcing information using the Conflict Minerals Reporting Templates (CMRT). Throughout FY2021, we continued to manage supplier communications and data via our CAS. In FY2021, Seagate’s entire product portfolio containing 3TG was validated as “DRC conflict free.” For the conflict minerals reporting period which closed midway through FY2021, (January 1, 2020 through December 31, 2020), CMRTs were collected from 100 percent of our in-scope suppliers. Every 3TG smelter or refiner in our supply chain conformed to the Responsible Minerals Assurance Process standards as of the close of CY2020. 50 FY2021 Global Citizenship Annual Report FY2021 Global Citizenship Annual Report 51

Slide 27 — Critical Materials

PRODUCT SUSTAINABILIT Y PRODUCT SUSTAINABILIT Y Seagate recognizes that in addition to 3TG, there are inherent procurement risks associated with other mineral-based products that we refer to as Critical Materials, which includes but is not limited to cobalt. Of the 35 mineral commodities designated as Critical Minerals by the United States Department of the Interior, 17 are present in our products. In FY2021, one additional mineral was identified as critical to our operations. An internal, interdisciplinary team at Seagate rated these 18 critical materials using a four-tiered risk rating across three risk domains. The risk ratings are specific to Seagate and are by nature temporally- variable; risks are re-rated annually at a minimum. In CY2020, two of the 18 minerals achieved a risk- score meeting or exceeding our internal threshold for reporting: cobalt and the rare earth elements (which we view collectively). Cobalt was rated highest for risk, as approximately two-thirds of the world’s cobalt is mined in the DRC (exposing it to similar risks as 3TG). As COVID-19 impacted these mining activities, the global supply of cobalt was put at risk of severe restriction. Seagate has extended our due diligence beyond what is required by law and maps the origins of cobalt in our supply chain via the RMI’s Cobalt Reporting Template (CRT). The CRT provides a standardized mechanism to share cobalt-sourcing data throughout the supply chain. Seagate has used the CRT to gather cobalt-sourcing information from all our direct material suppliers and makes this information available by request to customers. The high-risk rating of the rare earth elements is primarily due to uncertainty surrounding availability, as well as volatility in price. While the global demand for rare earth elements has doubled over the past 25 years, a single country controls the bulk of the world’s supply. This limited diversity in the origin of the rare earth elements, and the significant price swings seen over the last decade due to supply constraints, are concerning for Seagate, due to the need for rare earth elements in our products – especially our HDDs. Our circularity initiatives, particularly around the re-use of magnets, help address these concerns. Seagate’s risk management and compliance functions monitor news aggregators, industry association newsletters, and other information channels to maintain awareness of events that could affect our material supply chains. As needed, we coordinate with our supply chain to mitigate potential supply disruptions. Where possible, Seagate maintains multiple suppliers for each component we purchase to enable swift sourcing changes in response to risk, pricing, and availability challenges. Our commodities management organization reviews raw materials pricing trends on a quarterly basis to forecast spending changes. LOOKING FORWARD: RESPONSIBLE SOURCING OF MINERALS In FY2022, Seagate, in accordance with our Responsible Sourcing of Minerals policy, and in collaboration with RMI, will work to maintain our “DRC conflict-free” status. Seagate will also encourage more of our supply chain to use responsibly sourced cobalt. We intend to identify the next phase of minerals that will lead to responsible sourcing efforts.

Slide 28 — ENVIRONMENTAL SUSTAINABILIT Y

ENVIRONMENTAL SUSTAINABILIT Y Environmental Sustainability We first published our Environmental Footprint Reduction targets in 1999. Since then, we have maintained and expanded our public disclosures on environmental impacts each year. But beyond transparency of our track record, Seagate’s value of Integrity requires us to take meaningful and measurable action today on climate change. Seagate, along with industry peers and global stakeholders, must address the harm caused by materials depletion, power and water overuse, and waste. That is why Seagate has taken the first step by boldly and publicly pledging to reduce greenhouse gas emissions and marshalled expert resources toward this effort. We invite our customers and stakeholders to partner with Seagate to advance our common causes and collective efforts – and make an exponentially larger difference to the planet. Only this way will the industry achieve global goals of truly sustainable digital storage. Joan Motsinger Senior Vice President, Business Sustainability and Transformation Seagate recognizes that climate change and environmental damage are real and contributed to by human activity. We must be responsible to our people, the planet, and our own long-term sustainability as a company in working to reduce our impact.  06 Our global environmental sustainability efforts are part of how we do business. We regularly set goals to track our progress, and all efforts in reducing our energy consumption, carbon emissions, waste, and water usage are supported by senior management. Seagate works with several outside organizations, such as the RBA, UNGC, and SBTi to validate and further our efforts. We also educate our suppliers and key stakeholders on sustainability and performance measurement best practices. These actions comprise  the majority of our environmental sustainability efforts.  To the best of our knowledge, no Seagate operations  are owned, leased, managed in, or adjacent to protected areas and areas of high biodiversity value outside protected areas.

Slide 29 — Management Systems

ENVIRONMENTAL SUSTAINABILIT Y ENVIRONMENTAL SUSTAINABILIT Y Our environmental management system is shaped by ISO standards, the RBA Code of Conduct, UNGC principles, and stakeholder input, creating a platform for industry leadership in environmental sustainability. The management system’s effectiveness is evaluated through various channels, including management reviews, internal and external audits, and performance against targets. Overall, we believe the system functions effectively, and minor adjustments are made as needed. At the end of FY2021, all Seagate’s manufacturing sites maintained certification to the ISO 14001 Environmental Management System (EMS). The EMS covers the seven manufacturing sites and central function, similar to ISO 45001. Seagate had 18 environmental regulatory visits in FY202 (these include site visits, air monitoring, and wastewater sampling) and received no violations. We align with ISO standards in implementing energy management systems, with the goal of driving a common and sustainable energy management program at all manufacturing sites. All seven of our manufacturing sites are certified to the ISO 50001 Energy Management System. The ISO 50001 management system allows us to align to an established international standard. Our approach is to identify opportunities for energy conservation and improved operational excellence while being accountable to senior management. for the hydrofluorocarbon (HFC) solvent used in our manufacturing processes (a fugitive emission), and other chemicals that have high global warming potential. These are the main contributors to our Scope 1 emissions and are key to reducing our overall GHG emissions.  Seagate has been named to the CDP’s Climate A List 2020, highlighting our leadership in managing for climate change. We are actively working towards reduced GHG emissions and improving our TCFD disclosure. In addition, Seagate received an A- in Water Security and was ranked as a Supplier Engagement Leader. Management Systems Climate and Energy Seagate’s use of energy and process chemicals is required in manufacturing our products and providing our services. We will reduce related GHG emissions due to energy and process chemical use by identifying conservation opportunities, auditing our management systems, setting targets, and reporting our progress to employees, suppliers, and customers. The most significant environmental reduction opportunity is reducing GHG emissions in our operations. Our goal is to reduce both energy use and GHG emissions per storage capacity produced to measure the impact relative to the amount of economic activity taking place. Measurements vary across the industry and among product types; we measure energy and carbon emissions intensity per exabyte (EB) of storage capacity shipped. Seagate’s largest sources of scope 1 and 2 GHG emissions continue to be purchased electricity and fugitive emissions (an unintended release of GHG compounds into the atmosphere from various types of equipment and processes). We require all our manufacturing sites to set and achieve annual energy savings goals to reduce their GHG emissions intensity. Our product mix has migrated towards higher capacity drives in response to the rapid growth of the cloud- based storage market. While these products provide the highest capacity per unit, they typically require longer test times and run for a longer time, increasing GHG emissions per EB. We actively seek ways to mitigate the negative environmental impacts of these products. For example, we continue to search for a replacement WE REMAIN COMMITTED TO OUR SCIENCE BASED TARGETS:   “Global data storage solutions provider Seagate Technology Holdings PLC commits to reduce absolute Scope 1 and Scope 2 GHG emissions 20% by 2025 and 60% by 2040 from a 2017 base year. Seagate Technology Holdings PLC also commits to reduce absolute Scope 3 GHG emissions 20% by 2025 and 60% by 2040 from a 2017 base year. More on Science Based Targets here.”  Scope 1 and 2 (market-based) GHG emissions increased by 5.3 percent from CY2017 to CY2020. While we remain committed to meeting Science-Based Targets, our CY2017 baseline has been adjusted with the latest emission factors and assumptions to reflect actual conditions. We continue to take meaningful steps to meet our goals. The following are the actions we are taking to reduce our Scope 1 and Scope 2 GHG (market-based) emissions. For Scope 1, we are progressing on a project to replace a process chemical which is a large contributor to our Scope 1 emissions and hope to complete the project in FY2024. For Scope 2, we have initiated the purchase of renewable energy starting with our Northern Ireland facility and are evaluating renewable purchases at our other locations to mitigate Scope 2 emissions. 56 FY2021 Global Citizenship Annual Report FY2021 Global Citizenship Annual Report 57

Maintaining the system has posed challenges as it is difficult to obtain parts and components to keep the system functioning efficiently, resulting in less solar energy generated over time. **Seagate adopts The Greenhouse Gas Protocol: A Corporate Accounting and Reporting Standard (Revised Edition) to collect activity data and calculate emissions using an operational control approach. The emission data are reported for Scope 1 and Scope 2 as per the World Resources Institute (WRI)/World Business Council for Sustainable Development (WBCSD) Greenhouse Gas Protocol Corporate Accounting and Reporting Standard, and Scope 3 as per the WRI/WBCSD Greenhouse Gas Protocol Corporate Value Chain (Scope 3) Accounting and Reporting Standard.  Our Global Warming Potential (GWP) factors are based on IPCC Fifth Assessment Report (AR5 – 100 year). Other gases used in our Scope 1 calculations include CO2, CH4, N2O, HFCs, PFCs, SF6, NF3, 404A & 407C. Emission factors for electricity use are using EPA’s eGRID2019 for the United States and IEA’s CO2 Emissions from Fuel Combustion 2011 for outside the United States, used for Scope 2 calculations. For other energy, US EPA Emission Factor Hub, April 2021 (Fuels).

Seagate continues to face fugitive emissions challenges with the use of a hydrofluorocarbon solvent that has high global warming potential. This solvent is a necessary part of our media manufacturing process which we deploy in a closed-loop system with onsite recovery to minimize fugitive emissions. It is a priority for our media design and manufacturing teams to qualify a suitable replacement and reduce process emissions. Scope 3 emissions are typically much higher than Scope 1 and 2 emissions in the technology industry and driven primarily by product use and disposal. As products require more power and/or operate for longer durations, the emissions also change. By learning from current product analysis, we can better design future products to decrease our emissions. We use LCA results to inform us of sustainability impacts, including energy usage, along with other improvement areas such as packaging. Seagate’s goal is for each generation of products to be more efficient (TB/watt) than the previous generation.

Other energy efficiency projects are also targeted to save 10,000 MWh year over year. We expect to reduce Seagate’s Scope 3 indirect emissions and resulting carbon footprint by engaging our suppliers and customers through shared models, training, best practices deployment, and by increasing our influence across the industry. These actions build on our ISO 50001 certification for all manufacturing sites. Taken collectively, they will enable Seagate to meet and exceed our commitments to SBTs. CY2020 Emissions of Ozone Depleting Substances and Nitrogen Oxides, Sulfur Oxides, and Other Significant Air Emissions  In CY2020, there were no ozone depleting substances (ODS) recognized under the Montreal Protocol used in Seagate’s production. However, there was a total of 0.04 metric tons of CFC-11 equivalents used in test and development, and lab work.

Slide 36 — Waste Management

ENVIRONMENTAL SUSTAINABILIT Y ENVIRONMENTAL SUSTAINABILIT Y Waste from the manufacturing process is an inherent aspect of Seagate’s operations, which makes its management a priority. We have established programs to properly track, manage, and report all waste types across our global footprint; these programs assist us with categorizing different waste streams, ensuring the proper disposition in accordance with regulatory requirements. Our waste reduction initiatives strive to reduce environmental impact while generating the most benefit, where we first prevent waste from being produced, and then move to recycling or reusing waste where possible. Each Seagate site reports data on waste to a central database, which is accessible by employees and reviewed by Seagate Corporate Sustainability team to ensure we are adhering to best practices. Hazardous waste treatment vendors are qualified through a third- party audit of set criteria and have established minimum requirements for their selection and performance. Seagate had no significant spills (defined as one which is reported in the financial statements as a liability requiring outside response by a party external to Seagate) in FY2021.  Non-Hazardous Waste We measure the performance of our program by tracking the metrics listed in the graph that follows, taking into account recycling and energy recovery. Our annual totals include all waste generated at sites under Seagate’s ownership and control, not including waste generated as part of new construction projects.

When CHWMEG audit reports are not available, we directly contract with third-party firms to conduct audits of TSDFs. In FY2021, we conducted or reviewed four Hazardous Waste TSDF audit reports to ensure these facilities meet the standards set by Seagate Corporate Sustainability. A total of 9,481 metric tons of hazardous waste was transported to in-country TSDFs for treatment in FY2021. No waste was imported or exported during the year. The volume of waste transported is calculated from hazardous waste consignment notes that accompany the shipment for treatment and is validated by the TSDF. LOOKING FORWARD: WASTE MANAGEMENT In FY2022, we will continue to implement waste minimization projects at our sites. Our goal is to keep our hazardous waste generation totals below 10,900 U.S. tons and to continue to decrease our hazardous waste per EB. Seagate remains committed to reducing our hazardous waste volume in line with reducing our environmental footprint.

Our manufacturing processes use freshwater sourced from local watersheds shared with the local community. Freshwater is primarily used in direct operations and in our product value chain as cleaning agents at production sites, and to provide adequate cooling to sites and critical equipment. Note that all water noted in our charts and data callouts is classified as Freshwater (≤1,000 mg/L Total Dissolved Solids). Wastewater generated from our operations is treated and discharged into waterways used for other purposes, for example, transportation and irrigation. This makes the proper treatment of water an important aspect of our operations to reduce the impact to downstream activities. Seagate applies measures to reduce water consumption, improve water recycling, and reduce water intensity. Our water metrics are reported annually based on the calendar year. Our CDP Water Security Response and third-party verification can be found on our external Global Citizenship website. Water Stewardship Total Water Withdrawn Reduced To 7,529 megaliters in CY2020 from 8,029 megaliters in CY2019; total volume of water withdrawn from municipal water supplies (based on meter reading). None of our manufacturing sites are located in water stress areas defined by the WRI Aqueduct Tool. Water Recycled Increased To 3,028 megaliters in CY2020 from 2,775 megaliters of water (based on meter reading) in CY2019; progress driven by reducing water use through efficient processes and recycling water we do use. Water Intensity Decreased To 15.66 megaliters per EB in CY2020, from 21.91 megaliters per EB in CY2019. This is due to an overall reduction in withdrawal as well as the increased number of EBs shipped from CY2019 to CY2020. -6.22% +9.11% -29% 74 FY2021 Global Citizenship Annual Report FY2021 Global Citizenship Annual Report 75

The Senior Vice President of Business Sustainability and Transformation reviews water performance quarterly in alignment with water metrics tracked for water reduction. We monitor use at our sites on an annual basis, and when actual data is not available, we estimate use based on available data from other sites. We prioritize monitoring our manufacturing sites and largest R&D and administrative sites because they are the largest contributors to our water use. For smaller, office-based sites, water consumption is negligible. We perform annual water risk assessments for our prioritized sites using the WRI Aqueduct Tool taking into consideration the receiving water body and disclose information in our CDP Water Security Response. 0 0 72 0.02 100 2313 0 500 1000 1500 2000 2500 Other Irrigation & landscaping Cooling Tower / Evaporative Loss Megaliters Water Consumption by Use in CY2020 (Megaliters) All Areas Areas with water stress (risk area defined by WRI Aqueduct Tool) An important aspect of our operations is the treatment and disposal of wastewater from our manufacturing processes. We follow local authorities’ minimum standards for the quality of effluent discharge in all operations locations. These standards include pH, Biological Oxygen Demand, Chemical Oxygen Demand, Suspended Solids, and mineral content, among other priority substances of concern—primarily heavy metals relevant to electronic processes. Our treatment plants are built and maintained to ensure they operate efficiently in treating the effluents from our processes. We have internal operating control limits set well below the minimum discharge standards to act as internal triggers to ensure both internal and local effluent discharge requirements are met. Internal control limits take into consideration regulatory standards and system design parameters. We have established a water discharge monitoring plan that takes into consideration process capabilities and legal requirements for our sites. We prioritize monitoring for our manufacturing sites and Seagate’s largest R&D and administrative sites. This prioritization is necessary because water discharge quality is monitored by standard effluent parameters at all sites where wastewater treatment takes place on site. Our remaining sites discharge to municipal sewers as per local requirements and do not negatively impact surrounding ecosystems. 76 FY2021 Global Citizenship Annual Report FY2021 Global Citizenship Annual Report 77

Slide 41 — Singapore Reclaimed and Recycled

ENVIRONMENTAL SUSTAINABILIT Y ENVIRONMENTAL SUSTAINABILIT Y CASE STUDY Singapore Reclaimed and Recycled Water Project Our Recording Media Operations (RMO) in Singapore completed a project at scale to build a recycled water system. Natural water sources are limited in Singapore - 58 percent of fresh water is imported from Malaysia. To reduce the need for imported water, Singapore’s Public Utilities Board (PUB) reclaims local wastewater and provides the reclaimed water at a reduced cost, mainly to support commercial industries. The RMO project set out to implement new systems and enhance current operations to reduce our dependency and preserve this critical natural resource. The first phase of the project was to maximize reclaimed water usage in tool processes. This was achieved by upgrading and increasing the capacity of the current reclaim water system by installing additional filtration tanks. In the second phase, Seagate implemented a system that would recycle wastewater for use in cooling towers and other operational processes. Since operationalizing this project, Seagate has significantly reduced our dependency on reclaimed water from the PUB, and in FY2021 saved 658,132m3/year - the equivalent of $1.14 million/year. We were also able to successfully claim 50 percent of the project cost from the PUB for meeting the project requirements. With our learnings from this project, we are exploring recycling wastewater in our other Singapore sites. Our Seagate facility in Singapore is committed to saving water continuously and supporting “Go Green” initiatives. LOOKING FORWARD: WATER STEWARDSHIP In FY2022, Seagate plans to both reduce our water use and increase the amount of water we recycle. We will continue to invest in our treatment systems around the world to maintain compliance with all regulatory and permit conditions. 80 FY2021 Global Citizenship Annual Report FY2021 Global Citizenship Annual Report 81

Slide 49 — Building a Diverse Workforce

OUR EMPLOYEES OUR EMPLOYEES Building a Diverse Workforce In FY2021, Seagate continued to focus on building a more diverse workforce by recruiting talented candidates around the world. Taking steps to ensure hiring slates are inclusive of diverse candidates, Seagate strives to create a hiring process that is equitable, inclusive, and free from unconscious bias. We are creating a pipeline of diverse talent in the United States through partnerships with local and national diversity organizations, including the Society of Women Engineers (SWE), National Society of Black Engineers (NSBE), and the Society for Hispanic Engineers, as well Seagate values the unique experience military professionals bring to the workplace and encourages veterans who are transitioning from active duty to a civilian career, reserve members, and military spouses to consider a range of career paths at Seagate. as engaging in community outreach for groups including LGBTQ+ and United States veterans. In FY2021, in partnership with NSBE at the University of Minnesota, we provided opportunities for Black and minority engineering students to connect with Seagate, learn about our values, and interview for internship opportunities. In FY2021, we strengthened our talent pipelines in the United States military and veteran community. We partnered with the Army PaYs (Partnership for Youth Success) program, providing opportunities to military service members seeking to gain experience and skills from the private sector. This program underpins Seagate’s commitment to supporting United States military and veterans, and to strengthening our talent pipelines across the United States military and veteran community. Seagate collaborated with several Air Force Transition Assistance Program (TAP) Offices to provide United States Air Force veterans who have strong maintenance (Aircraft, Missile, Facilities, Munitions, & Vehicle) backgrounds with a link to a post-Air Force Technician career opportunity at Seagate’s Minnesota wafer manufacturing operation. We also began working with the United States Department of Defense (DOD) SkillBridge program. This is an opportunity for United States service members to gain valuable civilian work experience through specific industry training and apprenticeships during the last 180 days of service. SkillBridge connects Service members to Seagate in real-world job experiences. Our University Relations team expanded their military outreach as well, with two information sessions in Colorado for military students and adult learners. Seagate’s Facebook and Instagram platforms provide an opportunity to share the “Life at Seagate” story with candidates on social media, and illustrate the diversity of our employee base through our global offerings. We are also active on key recruitment sites across the globe including JobStreet, LinkedIn, and Glassdoor. To increase outreach with women candidates, we partner with Fairygodboss. For the second year in a row, Seagate was named one of the Best Technology Companies for Women in 2020. To be considered for this honor, firms are ranked by Fairygodboss based on positive reviews from employees about the company’s commitment to gender inclusion, senior leadership support, and workplace culture. 96 FY2021 Global Citizenship Annual Report FY2021 Global Citizenship Annual Report 97

Slide 50 — Retention

OUR EMPLOYEES OUR EMPLOYEES Retention Seagate prioritizes retaining and developing our talented workforce as we believe that reducing turnover helps retain knowledge and deliver deeper, longer-term customer relationships. Our voluntary annual turnover for non-operator employees remains below 10 percent, which is below our industry average. Seagate offers retirement transition services, such as pre-retirement planning information and resources, for employees that are leaving the workforce due to retirement. In FY2021 we introduced a phased-retirement pilot program in the United States, the United Kingdom and Singapore. This voluntary, employee-initiated program provides a period of transition from working full-time to part-time, prior to leaving Seagate on an agreed-upon date. In the United States, in situations where reductions in workforce are required, we provide outplacement services and in other countries, we align with legal mandates.

Slide 52 — Interfaith

OUR EMPLOYEES OUR EMPLOYEES Supporting ERGs One way that Seagate supports a culture of inclusion is by empowering diverse Employee Resource Groups (ERGs). These voluntary, employee-led communities provide a safe space for discussion, connection, networking, and professional development. With over 2,300 global members representing nine ERGs and over 25 local chapters, ERGs are a vital component of our commitment to building a workplace culture where all employees feel safe, respected, and valued. Seagate believes that all employees should be paid fairly and equitably, reflecting our DEI commitments and our values of Integrity and Inclusion. To deliver on that commitment, as well as remain competitive in the market for talent, Seagate analyzes the competitiveness of our programs at least annually to ensure compensation pay ranges and targets are in line with similar companies that are seeking like talent. In addition to market analysis, we continually benchmark compensation best practices to provide employees with a competitive total compensation package. We also review our compensation practices on an annual basis to ensure pay is fair and equitable. In partnership with an independent third-party, we look at pay parity based on gender, and in the United States, we look at race as well. Additionally, Seagate provides development programs that are designed to eliminate bias in all employment decisions including performance and compensation. Support human rights and greater equality through networking and professional development events. Engage in efforts that promote diversity and inclusion within Seagate and the community.

Slide 54 — Employee Performance, Development, and Engagement

OUR EMPLOYEES OUR EMPLOYEES Employee Performance, Development, and Engagement Seagate aspires to create an environment that brings out employee performance through rich conversations and coaching, collaboration, and diverse thought. This is underpinned by our performance management process, where employees develop goals each year via conversations with managers and our online Virtual Coach resources. Ongoing dialogue around these goals is intended to help managers and employees identify strengths, improve outcomes, and close performance gaps. We provide talent management and learning solutions that enable our employees to reach their full personal and professional potential at Seagate. Performance Management Building our talent from the ground up is an essential part of our people strategy at Seagate. Managers have the power to influence our workforce by determining and uplifting our talent now and for years to come through our goal setting and performance review cycles. Seagate’s operator employees receive direct ongoing feedback and coaching throughout the year from their supervisors. Our non-operator employees are encouraged to develop two to three clear goals aligned to our overall company strategy. In FY2021 we set a goal of 99 percent of non-operator employees participating in the performance management process; 99 percent completed the goal setting and year-end review process in our online system, and 100 percent* received a year-end goal review with their manager. *Includes training from the Seagate Learning Platform, LinkedIn Learning, and the Leadership Program. Change in reporting methodology from prior year to only include non-operator by gender as this information is captured in our leaning management system and operator training is tracked across multiple platforms. Average Training Hours *This process does not include 1) operator employees, 2) sales and sales management employees, and 3) employees hired after 01-Jun-2021. Learning and Development As part of the performance management process, managers and employees work together to build personalized development plans. In FY2021 99 percent of our non-operator employees had created development plans. Whether our employees want to go deep into their craft as a subject matter expert, or they want to expand their skill set by moving around and trying something new, Seagate provides development programs to enhance career growth and development. Employees can build skills, gain experience, and learn new things through: • Face-to-Face training • Seagate E-Learning and Classroom Learning Opportunities • LinkedIn Learning Self Study Courses and Programs • Strategic Internal Programs (such as: Breaking Bias, Citizen Data Scientist, Firmware Engineering, Leadership Training, Management Essentials) • Tuition Reimbursement for Outside Degree Programs • Internal Mobility Opportunities through Career Discovery • International Assignments • On-the-Job Training • Seminar and Conference Opportunities • Mentoring and Coaching NON-OPERATOR* GENDER AVERAGE HOURS Female 11.5 Male 11.9 OPERATOR Our operator employees have a comprehensive training plan that includes a combination of classroom training and on-the-job training based on job function. Training needs for operator employees are managed and tracked at our manufacturing sites. 106 FY2021 Global Citizenship Annual Report FY2021 Global Citizenship Annual Report 107

Slide 55 — UNDERSTAND

OUR EMPLOYEES OUR EMPLOYEES LOOKING FORWARD: EMPLOYEE PERFORMANCE, DEVELOPMENT, AND ENGAGEMENT In FY2022, Seagate will continue to develop and upskill our employees in leadership skills, technical skills, core people skills, and more. We will continue our Management Essentials program with an intermediate series featuring expanded topics in a blended learning format. We will also launch additional cohorts of our Leadership Essentials Program and expand our Talent Acceleration Program—a strategic global initiative that offers various tracks to increase our employees’ capabilities in critical skill sets. To support these activities, our learning system will be added to the SAP SuccessFactors platform to deliver and align with Seagate’s standard global employee experience and be a one-stop-shop for learning opportunities to help employees develop their skills. Our annual employee experience survey will continue to be a valuable vehicle in providing employees with an opportunity to give anonymous feedback, encourage manager and employee conversations, provide managers with suggestions to create impactful action plans, and deliver employee engagement metrics and key engagement drivers to track over time. We are also focused on our next generation of leaders and in FY2021, we continued our Organizational Talent Reviews (OTR) process where managers evaluate each member of their organization to identify employees’ potential and determine successors. The outcomes of the OTR process help leaders determine our “Top Talent” employees and where they can maximize their development resources. Our leaders and managers are offered opportunities to learn effective models and tools from industry experts, and share insights and reflections with peers to further sharpen their management and leadership skills. Our Management Essentials training provides new and experienced managers with the opportunity to build or refresh leadership skills. This blended learning approach uses self-paced modules in conjunction with live virtual sessions. It focuses on individual and team goal setting, development of effective learning plans, evaluating performance, and how to help increase a team’s diversity of thought and engagement. In FY2021, we launched our Leadership Essentials Program. The three cohorts were comprised of 101 employees from multiple job levels (Professionals, Managers, and Directors) across the globe (41 percent Americas, 52 percent APAC, 7 percent EMEA). The main objective of the program is to equip our leaders with the ability to lead with character, competence, commitment, agility, and a ‘Mission First, People Always’ approach. The multi-week digital leadership journey is hosted by an external training partner and organized into three phases—Lead Yourself, Lead Teams, and Lead with Purpose. The program creates an engaging, iterative development process that allows time to translate knowledge into action and explore practical application. Our goal is to expand this program and support all director-level employees in completing the program within the next two years. Our Career Discovery program is also a component in the development of our employees. Career Discovery helps our employees find internal opportunities to grow their careers. It also gives employees the opportunity to find and work on projects in other functions within the organization, where their skillset and expertise might be well suited, or gives them the opportunity to learn something new. The tool is also a place where employees can find or become a mentor, to allow employees to share career advice, knowledge, networking, and skill development. Employee Experience and Engagement A positive employee experience is critical to attract, retain, and engage the talent we need to remain a successful company. Seagate regularly surveys employees to solicit feedback and to understand employee engagement, as well as employee perceptions on topics such as leadership, development, Seagate core values (Integrity, Innovation, and Inclusion), and belonging. In our FY2021 survey cycle, Seagate expanded into a broader employee experience survey, asking questions that touched on the entire Employee Life Cycle, and additional leadership, diversity, and work-life balance questions. The survey concluded in early 2021, with more than 36,000 global employee respondents (92 percent participation rate). Just as in years past, all responses were confidential so employees can freely respond and share their feedback. In this last survey, we also introduced customized results that revealed key drivers of engagement for each organization. Once the survey concluded, results were analyzed, then shared with management. Managers then followed the new three-step process to Understand, Share and Take Action! Then they reviewed and evaluated their data, shared their data with their teams and discussed results, and then built targeted action plans with their team. UNDERSTAND Understand the survey results: Engagement Index and Key Drivers SHARE Hold a Feedback Meeting with your team to share and discuss the survey results TAKE ACTION Build an Action Plan with your team, follow through on planned actions and communicate progress The Three-Step Action Process 108 FY2021 Global Citizenship Annual Report FY2021 Global Citizenship Annual Report 109

Slide 56 — Benefits and Wellbeing

OUR EMPLOYEES OUR EMPLOYEES Benefits and Wellbeing Seagate’s Total Rewards program is a key component of our people strategy and is designed to attract, motivate, and retain employees. Key components of the Total Rewards program are employee health benefits and wellbeing programs. Our benefits are benchmarked to local market practices, industry norms, and cultural requirements, and reflect our standards as a competitive, multi-national organization. Our wellbeing programs provide resources to support employees in living a healthy lifestyle, and promote physical and mental health, as well as financial acumen. While plans differ geographically, all offer value and flexibility in support of Seagate employees, and, in some cases, their dependents. All regular full-time employees are offered comprehensive benefits coverage, including health care, wellness programs, parental leave, paid time off, retirement savings opportunities, life insurance, and equity ownership opportunities. Specific benefits offered vary by country. Our global Healthy Journeys wellness program seeks to educate, encourage, and support our employees as they work on achieving their health and wellness goals. Because our benefits programs are managed at a country or site level, the Healthy Journeys program varies from location to location. All employees have equal access to the programs offered through Healthy Journeys. Some of these offerings are in-person and some are virtual. COVID-19 has impacted the way in which we have offered support, with more focus on virtual programs, but it has not changed our commitment to support employee overall wellbeing. APAC (Asia Pacific) In Asia in FY2021, we lived our Healthy Journeys vision by supporting a culture of health and wellbeing for our employees. We continued our Self-Care campaign into early FY2021, offering simple and easy self-care tips. This campaign encourages employees to “check in” and learn daily tips on topics such as mindfulness, self-compassion, and nutrition. Overall, the Self-Care campaign attracted 7,300 participants and garnered 28,000 check-ins. 110 FY2021 Global Citizenship Annual Report FY2021 Global Citizenship Annual Report 111

Slide 57 — Unleashing Creativity:

OUR EMPLOYEES OUR EMPLOYEES Legacy Program In FY2021, Seagate introduced a pilot program in the United States, the United Kingdom, and Singapore called the “Legacy Program.” This program aligns with our people strategy, which is designed to enhance the employee life cycle from hiring to retiring. The Legacy Program provides a period of transition available to certain eligible professional and managerial employees who are ready to transition out of their employment with Seagate. The Legacy Program offers a phased approach, where employees will:  • Work a reduced schedule • Transition their expertise to other employees, or take on a mentor role; and/or  • Undertake a project of fixed duration to see through to completion The Legacy Program is a voluntary, employee-initiated period of transition from working full-time to part- time, prior to leaving Seagate on an agreed upon date. This program is being reviewed for possible expansion to include additional job levels to support employee desires as well as the needs of the business.    Seagate also launched Wellbeing 365 for the entire region in FY2021. This program offers our employees and their dependents access to qualified providers who can support them with a variety of life issues in order to enhance their emotional, social, financial, and physical wellbeing. Wellbeing 365 includes a hub that provides comprehensive online resources such as articles, tips, and toolkits that can be accessed any time. In China, Singapore, and Thailand we offered health screenings and more than 80 percent of employees at these locations completed their checks either on or offsite. Toward the latter part of FY2021, we hosted an onsite vaccination program for our employees in China and India, which will continue in FY2022. LOOKING FORWARD: BENEFITS AND WELLBEING In FY2022, Seagate will continue to operationalize and promote our global health and wellbeing programs with both agility and sustainability through and beyond the pandemic. We will continue to promote digital health activities such as virtual doctor visits, virtual physical therapy (United States only) and virtual counseling appointments for employees in countries where these are available. We will also promote mental wellbeing with country specific programs. Once COVID-19 controls and thresholds permit, we will re-introduce onsite programs and health screenings for our employees. Unleashing Creativity: Celebrating Families with Children’s Drawing Contest Family is one of the most important facets of our lives—and especially so during the COVID-19 pandemic. To encourage quality family bonding time, Seagate’s Total Rewards team organized a children’s drawing contest that was open to children of Seagate employees across the company’s Asia- Pacific sites. With the theme of “Family” to guide them, participants were asked to show what family meant to them through their drawings. The contest drew nearly 300 submissions, with an array of impressive artwork. With three categories for children ages 3 to 6, 7 to 12, and 13 to 15, submissions were judged based on theme, creativity, and art proficiency. The top 20 submissions from the 3-to-6 and 7-to-12 age categories each received a set of coloring stationery and a Lego set, respectively. These prizes promote and encourage employees to spend quality time with their children and families. EMEA and the United States In EMEA and the United States, a video-based wellness platform was rolled out in FY2021, eliciting positive feedback from employees on this virtual offering. The platform provides access to thousands of video-based programs focused on exercise, nutrition, resilience, and stress management as well as financial education. Seagate encouraged employee participation in these online offerings by providing raffle prizes as incentives for completing various challenges on this portal. In addition, for employees in the United States who wanted personalized health coaching, we added a virtual health coaching option with a licensed coach through our medical plan vendor. To support employees’ mental wellbeing, we continued to offer several Employee Assistance Program webinars on the topics of resilience, fitness essentials, stress management, and financial wellbeing. 112 FY2021 Global Citizenship Annual Report FY2021 Global Citizenship Annual Report 113

Slide 58 — Health and Safety

OUR EMPLOYEES OUR EMPLOYEES Health and Safety The health and safety of Seagate employees, contractors, and visitors is an important aspect of our organization. The pandemic has highlighted the important connection of workplace health and safety, and the role it plays with our visitors, contractors and our communities. Seagate’s tireless efforts and rigorous EHS programs and standards have ensured that we operate to the highest level encompassing all factors that impact the health, safety and wellbeing of our employees. All Seagate locations and work activities are covered under the health and safety management systems, and all manufacturing sites have their health and safety management systems certified to ISO 45001. Our global health and safety standards, as well as our accompanying management systems, frequently go beyond country or industry-level guidelines. In FY2021, Seagate remained a safe place to work and continued to perform well under safety and health industry averages, based on calculations determined by the United States Occupational Safety and Health Administration (OSHA). Seagate uses the OSHA definitions for injury types and injury rates. The hazard profile of Seagate is typical of an electronics manufacturer and includes slips, trips, and falls, and ergonomic injuries among others. Our current health and safety management systems support continuous improvement across our risk reduction and mitigation efforts. The strategies we have implemented for reducing risks associated with work-related injuries and illnesses are backed by more than a decade of collecting health and safety performance indicators. GLOBAL HEALTH AND SAFETY BY THE NUMBERS IN FY2021 AMOUNT Work-related fatalities 0 Recordable case rate1 0.23 Days-away case rate2 0.12 Health and Safety regulatory visits hosted 67 Notice of violation findings None Fines levied None Health and Safety eLearning courses held and completed with “satisfied” completion status3 91,517 Meals served globally per month (average)4 587,680 Foodborne illnesses reported 0 Miles that Seagate bused employees 5,777,601 miles Vehicle incidents per million miles traveled5 1.7 1 Total Recordable Case Rate (TRIR) Total Recordable Incidents x 200,000 / Total Hours Worked  2 Lost Workday Rate (DART-L) Total Lost Workday Incidents x 200,000 / Total Hours Worked  3 Examples of EHS eLearning courses include: Office Production and Remote Ergonomics, Laser Safety, Confined Space Awareness and Permit Required, Electrical Safety Awareness, Lockout Tagout, Chemical Handling, and General EHS Awareness.

Slide 59 — 116

OUR EMPLOYEES OUR EMPLOYEES The Environment, Health, Safety and Sustainability (EHS&S) Policy reinforces Seagate’s commitment to a safe workplace underpinned by our values of Integrity, Innovation, and Inclusion. This policy, along with site initiatives and training programs, supports the active collaboration, consultation and participation of employees and other stakeholders such as safety representatives, agency temps and contractors. This empowers every worker to actively identify and eliminate hazards, anonymously report concerns, incidents and near misses, and exercise the “stop work authority” without reprisal. Involvement is enabled through participation in site safety committees, emergency response teams, incident investigation teams, risk assessments and tools such as safety suggestion boxes. Results of risk assessments, incident investigations, drills, and lessons learned are shared with relevant stakeholders for transparent and open communications. The Cority EHS Enterprise Software platform system provides our EHS team with integrated and centralized data, standardized processes, and the ability to track, trend, and analyze EHS performance and Key Performance Indicators (KPIs). Using this information EHS can proactively mitigate risks, meet compliance requirements, identify problem areas, track and manage incidents, and monitor overall safety performance. Over 50 percent of all work-related injuries are caused by two incident types - slip, trips, falls and Ergonomic Musculoskeletal Disorders. Seagate has extensive programs, initiatives, training, and communication dedicated to incident reduction in these two areas both at site and global levels. Company and site scorecards reflect targets dedicated to incident reduction, and hazards and risks are identified through risk assessments to establish the required hierarchy of controls and response to these focus areas of concern. This data is incorporated into our total hours worked and recordable/lost time incident data for employees, contractors, interns and agency temps under Seagate control. No workers have been excluded except for those not within Seagate control whose hours and incidents are reported through their respective organizations. To mitigate the likelihood of work-related hazardous events or exposures and prevent negative outcomes to employees, contractors, interns, agency temps, assets and other resources, Seagate thoroughly and regularly evaluates the risks and hazards relevant to our operations, services, and sites. Seagate’s top identified risks include COVID-19; ergonomics; slip, trip, falls; chemical storage; and handling and struck-by injuries. This risk assessment process is conducted by trained employees and a cross-functional group of subject matter experts to ensure workers at all levels participate in the identification and elimination of hazards and the implementation of hierarchy of controls. 116 FY2021 Global Citizenship Annual Report FY2021 Global Citizenship Annual Report 117

Slide 60 — Health and Safety: Process Chemistry

OUR EMPLOYEES OUR EMPLOYEES Seagate’s Occupational Health services focus on total worker health by utilizing policies, programs and practices that integrate protection from work-related safety and health hazards with the promotion of injury and illness prevention efforts and worker well-being. The onsite Occupational Health clinics see approximately 60,000 clinic visits on average, annually. Occupational Health services include medical surveillance, emergency support, work-related case management, injury and illness visits, pre- and post-employment physicals, fitness for work assessments, and wellness program support. Worker personal health-related information is maintained confidentially by certified and licensed medical/nursing staff in the Cority-Occupational Health module. Seagate’s Occupational Health also provides service to onsite contractors and visitors if they have symptoms onsite; we also provide occupational medical examinations to an onsite contractor who works under Seagate supervision. Contractors working at Seagate locations are required to comply with Seagate Health and Safety procedures, which utilize the hierarchy of controls in addressing health and safety risks at our locations. Those working to build Seagate products and components at supplier sites are subjected to the RBA Code of Conduct; details are provided in the supply chain section of this report. Seagate will continue to maintain ISO 45001 Occupational Health and Safety certification. We had 67 health and safety and fire regulatory visits globally in FY2021. There were no violations or citations in FY2021. a unified industry approach to chemical data collection and reporting. Seagate is a member of CEPN and contributed materially to the development of the PCDC Tool. Seagate will continue to use the PCDC Tool to develop an inventory of the chemicals that are used in our supply chain as well as to gather information on how those chemicals are used and what worker health and safety protections are in place. We use this information to better understand where opportunities exist in our supply chain for interventions to ensure safe conditions for workers. In FY2021, Seagate completed the process chemical documentation for all manufacturing sites, which we plan to continue annually, and also completed training materials for members of our supply chain and other electronics industry companies. LOOKING FORWARD: BENEFITS AND WELLBEING, HEALTH AND SAFETY In FY2022, Seagate’s EHS and Occupational Health strategy will focus on evolving and expanding our EHS efforts beyond traditional occupational safety. Seagate’s efforts, programs, and initiatives will continue looking at safety as it relates to infectious disease, mental health, and remote work in addition to our site operational risk. We will be placing a heavy emphasis on revising our company-wide ergonomic program, along with revising our programs and requirements for chemical management, emergency preparedness and response, and communicable disease. We will continue to focus our efforts on COVID-19 response and long-term COVID-19 resourcing and strategy, paying close attention to science, data, and our health authorities to ensure we are making informed decisions and implementing the best EHS controls for our employees. Seagate recognizes that our commitment to ensuring that workers are not exposed to hazardous chemicals does not stop at the walls of our factories and extends throughout our supply chain. The first step in this journey is understanding the chemicals used at each of the many steps in the supply chain. We have developed our Enterprise Chemical Management System (ECMS), a single, global platform for selection, ordering, tracking, use, and disposal of all chemicals used in our products/ manufacturing to standardize practices, meet customer and regulatory reporting requirements, reduce costs, and support business process management across all Seagate sites. To enable the effective transfer of chemical usage information between companies, the CEPN developed the Process Chemicals Data Collection (PCDC) Tool as Health and Safety: Process Chemistry 118 FY2021 Global Citizenship Annual Report FY2021 Global Citizenship Annual Report 119

Slide 61 — Community

Community Engagement 08 Seagate’s community engagement program puts our corporate values into action in support of education and well-being. In FY2021, Seagate continued to offer community engagement opportunities at our major sites (500 or more employees), which covers 96 percent of our workforce. Our community engagement stakeholders include employees, local community members, nonprofit partners, civic and academic institutions, and governments. In FY2021, Seagate led and participated in more than 160 different engagements and partnerships around the globe. This was a decrease from previous years, as some programs were suspended due to COVID-19. In this environment, we continued our pivot begun in FY2020 to direct a large portion of our efforts and resources toward pandemic relief in local communities. Seagate nonetheless continued our long-standing tradition of delivering hands-on STEM targeted programming to K-12 students. In many cases, modified/hybrid and virtual footprints were used to deliver STEM efforts in age-appropriate ways that allowed for fun as well as learning. With an emphasis on STEM, as well as health, wellness, and environmental opportunities, Seagate has built a community engagement program designed to provide support to the communities where we work and live. With multiple large sites across the globe, our community engagement program reflects Seagate’s vertically integrated business model. Accordingly, the program is highly localized, involving a cross-functional process to identify opportunities that are meaningful locally. We involve not only our employees, but also local community members, nonprofit partners, civic and academic institutions, and governments.   120 FY2021 Global Citizenship Annual Report FY2021 Global Citizenship Annual Report 121

Slide 62 — Helping the Community During COVID-19

COMMUNIT Y ENGAGEMENT COMMUNIT Y ENGAGEMENT Helping the Community During COVID-19  The economy surrounding our Korat, Thailand facility is heavily dependent on agriculture, and COVID-19 constrained the local market, resulting in overproduction of crops. Seagate organized a project to help local farmers manage an oversupply of sweet corn by boosting consumption through subsidizing the purchase of corn directly from farmers. The corn was delivered to the Korat facility, and more than 10,000 employees purchased 65 tons in one week. Seagate also donated six more tons of corn to 46 schools in the area, as well as to the local Sungnoen community to promote corn as a healthy food choice. In Northern Ireland, Seagate collaborated with Ulster University and Dell Technologies to combine research and data storage capabilities that will enable advanced analyses of COVID-19 patient data. The partnership created infrastructure enabling a petabyte of data, supporting the Ulster University research team’s efforts to examine large volumes of medical data to establish links between COVID-19, genetic make- up, and the severity of the disease. The findings will inform decisions around drug treatments for those with severe symptoms and possibly long-haul COVID-19, as well as providing insights into how genes may influence vaccination efficiency. The partnership has delivered the infrastructure to store patient information for this major research project at the Northern Ireland Centre for Stratified Medicine based at C-TRIC on the Altnagelvin hospital campus.  STEM Ongoing Support, with a Creative Shift due to COVID-19   In California, Seagate employees mentored local students through a pilot partnership with San Jose State University and Santa Clara University. Three virtual panel events were held; mentors shared their experiences and advice with students on kickstarting their careers, interviewing practices, networking, and other helpful career-related topics. Mentor-speakers also answered questions from students and made direct connections through online platforms. The new partnership was a success, with university representatives giving a resounding appreciation for Seagate’s efforts. Seagate employees in Northern Ireland partnered on virtual volunteer opportunities with Speakers for Schools, a UK-based charity established to provide online opportunities for students 16-17 years of age. The local team developed skills in Google Classroom and created content offering insights into a career at Seagate and the potential pathways into engineering. The result was the delivery of two virtual Google Classroom experiences for students aged 15-18 years, reaching 44 schools and 98 students across NI, Manchester, London, Cardiff, and York. Minnesota employees provided grants to six local robotics teams to support their work to provide personal protective equipment (PPE) to frontline workers as COVID-19 challenged the supply chain for safety 122 FY2021 Global Citizenship Annual Report FY2021 Global Citizenship Annual Report 123

COMMUNIT Y ENGAGEMENT COMMUNIT Y ENGAGEMENT equipment in the state. The grants helped purchase needed materials for teams to use 3D printers to create the parts needed to make face shields. Additionally, we sponsored virtual robotics tournaments in place of in-person tournaments. Seagate also provided funding to Minnesota STEM Partnership, a nonprofit that is making STEM more accessible to students of color. In China, Seagate sponsored two sessions of hands- on STEM learning for 100 local primary school students. Due to the pandemic, the participants were separated into two sessions on two different days. Each session lasted for four hours, including a plant tour, HDD introduction, hands-on experiment, a VR technology experience, and robotic gaming.  Continuing support of local Health and Human Services organizations  In Colorado, employees continued their ongoing support of local food banks and social service organizations. Volunteers created care packages for homeless veterans and donated school supplies for children in need. Seagate volunteers in China picked up paint brushes to help a local community improve living conditions for 150 local senior citizens. Volunteers painted the house walls with beautiful pictures and fences with bright colors. Our Singapore research and development site collected book vouchers for children from the Singapore Children’s Society (SCS) during the Christmas festive season, to help them with their back-to-school needs. Seagate also made a financial donation to support the programs for the children at SCS. Some of these programs include casework and counseling, financial aid, workshops and camps, as well as information and referral services. In Johor, Malaysia, we collaborated with the Universiti Teknologi Malaysia, a local university that is teaching families to use historical data to improve the yields of farming vegetables with the goal of enabling families  to grow their own vegetables for consumption. The farmers who have successful crops sold the extra vegetables within their community to help support their families. This project helped families in need in Johor, especially those affected by the pandemic. LOOKING FORWARD: COMMUNITY ENGAGEMENT In FY2022, Seagate will focus on volunteer opportunities to encourage employee engagement and foster positive awareness of Seagate in the communities where we work and live. We know communities are still suffering from the long-term effects of COVID-19. We will continue to pivot our programs to address the changing needs and challenges facing our communities. Our plan is to increase educational outreach and programs that focus on how our technologies, products, and the larger datasphere can benefit the next generation. 124 FY2021 Global Citizenship Annual Report FY2021 Global Citizenship Annual Report 125

Slide 64 — Supply Chain

Supply Chain Seagate is a global company with diverse operations; agility is key in meeting customer and market demands. Our supply chain is an extension of our footprint, and stakeholders hold us responsible for the performance and actions of our suppliers. This makes supply chain diligence important to Seagate. Through education, strategic management, and transparency to and from our manufacturers, and suppliers, Seagate seeks to ensure that people in our supply chain are treated fairly, and resources managed responsibly. Seagate has two categories of suppliers; direct (those that provide components and parts of our products), and indirect (those that provide products and services that support our operations). Our supply chain responsibility program has four aspects: Code, Capacity Building, Risk Assessment, and Remedy. The objective of the program is to ensure our supply chain acts responsibly and implements remediation when issues are identified. Seagate’s Supply Chain organization has full-time staff and dedicated resources to implement and monitor supply chain compliance. The management system’s effectiveness is evaluated through various channels including management reviews, internal and external audits, and performance against targets. We believe the management system is functioning effectively, and minor adjustments are made as and when needed. The RBA Code of Conduct also serves as the code of conduct for our suppliers, and we expect that 100 percent of suppliers will comply. We expect our suppliers to pass the RBA Code of Conduct to their suppliers and hold them to the same standards that we hold them to. Our supply chain responsibility program aligns with the RBA tools and processes provided. We align with the RBA because we believe an industry wide standard is the most efficient way to set expectations and carry out verification throughout the supply chain. The RBA Closure Audit is the preferred option for verifying successful closures of audit findings; Seagate’s requirements are documented in our CSOP and communicated to our supply chain partners. Supplier audit performance and closure findings are scored in the Quarterly Supplier Scorecard for the affected supplier(s). 09 126 FY2021 Global Citizenship Annual Report FY2021 Global Citizenship Annual Report 127

Slide 65 — Supplier Engagement and Collaboration

SUPPLY CHAIN SUPPLY CHAIN Seagate regularly meets with suppliers to share expectations and evaluate our level of engagement, this proactive approach with suppliers helps to ensure our goals and standards are aligned. We require onsite service providers, such as canteen and janitorial services, to adhere to Seagate’s Standard Operating Procedures to ensure that all onsite service providers are held to the same standards as our own workforce. Seagate does not currently use foreign labor via agents, and we partner with recruitment agents at various locations, including Thailand, China, Singapore, and the United States, who provide local talent. Our Supply Chain organization has fulltime staff and dedicated resources to monitor RBA compliance and education and ensure adherence to applicable global and local laws. Seagate conducts multiple Executive Business Reviews to ensure success within our supply chain. These reviews include supplier RBA compliance efforts with supplier leadership. Through collaboration with our suppliers on key projects that focus on issues like RBA Code of Conduct conformance, financial sustainability, and process improvement we are able to innovate and scale for everyone’s benefit. In FY2021, Seagate partnered with third-party providers to deliver supplier training via six webinar sessions with nearly 600 supplier participants. These webinars included topics on responsible sourcing of minerals, RBA Code Version 7.0, emergency preparedness, forced labor. The webinars were designed to include implementation of the RBA Code of Conduct, and how to develop effective corrective action plans for actual audit findings in these topic areas. We also held a session on COVID-19 response to ensure suppliers were managing their operations in line with RBA Code expectations during the pandemic. We held no face-to-face sessions as COVID-19 restrictions impacted our annual training plans. Our Anti-Slavery and Human Trafficking statements are posted on our website in adherence to the California Transparency in Supply Chain Act and United Kingdom Modern Slavery Act to demonstrate our efforts as a company in preventing slavery and human trafficking in our business and supply chain. Seagate has an active presence in the RBA. Our involvement helps us be a better global citizen and also provides the opportunity to work with peers to drive improvements in the global supply chain. We are proud to have a continued major role in the RBA, with our Senior Vice President, Business Sustainability and Transformation serving as Board Chair in FY2021, and serving in the Executive Committee and as Board Chair in FY2021. Through our audits in FY2021, cases of high recruitment fees by our suppliers involving foreign migrant workers in Malaysia and Thailand were identified. During the year, we worked with the RBA and other customers of these suppliers to confirm the allegations and quantify the amount of fees involved. Identification of recruitment fees, especially in a worker’s home country, has been extremely challenging, but is very important in protecting workers in our supply chain, and maintaining integrity as a company. We continue to work closely with the RBA and other customers to address this issue. In FY2021, approximately $1.2M was reimbursed by those suppliers to over 2,000 workers. Six suppliers completed their remediation actions and we are continuing to track the remediation of two other suppliers. We will maintain our engagement with our suppliers to ensure ethical recruitment practices are adhered to while hiring workers. Supplier Engagement and Collaboration Supply Chain Due Diligence Seagate’s supplier due diligence process considers a number of factors (such as type of supplier, spend, onsite or offsite) in determining suppliers who fall within the scope of our RBA programs. Seagate uses the Self-Assessment Questionnaire (SAQ) and Validated Audit Program (VAP) as our primary risk assessment tools. The SAQ assesses risk in these four areas: social impacts, health and safety, environment and ethics. With these tools we are able to determine any instances of non-conformance with the RBA Code of Conduct and obtain root cause and corrective action plans as needed. Training on the RBA Code of Conduct and our expectations is given either directly to suppliers, or through tools provided by the RBA. Seagate’s existing suppliers, and 100 percent of new suppliers identified in the scope of our policy, are screened annually. The SAQ assesses supplier compliance with code requirements. Seagate’s expectation is for our suppliers to conform to the latest version of the RBA code of conduct, utilize only certified 3TG smelters and respond to the RBA Environmental survey. In FY2021, 169 suppliers either completed or updated their SAQ and released it via the RBA-Online system. Seagate requires all of our direct materials suppliers with whom we spend at least $1 million annually, as well as selected indirect suppliers, to undergo the RBA VAP audit process. Doing so helps to ensure integrity and verify conformance with the RBA Code of Conduct. These audit reports are valid for two years, meaning our suppliers are on a two-year audit cycle. 128 FY2021 Global Citizenship Annual Report FY2021 Global Citizenship Annual Report 129

Slide 67 — Supplier Diversity

SUPPLY CHAIN SUPPLY CHAIN China 31% Thailand 27% Malaysia 10% Japan 7% Singapore 4% Vietnam 4% Korea 4% Philippines 4% UK 1% Switzerland 2% Mexico 2% Taiwan 4% FY2021 Supplier Audits by Country Our global customer base, local communities, employees, and suppliers make up a diverse network that spans the globe. To encourage diversity in our supplier base, Seagate regularly contracts with diverse suppliers who qualify and successfully compete for our business; there is great value in minority-owned businesses. For example, diverse suppliers in the United States are welcome to participate in Seagate’s competitive bidding process, including businesses owned and operated by minorities and those located in historically underutilized business zones. We are proud to play a part in helping diverse suppliers grow, create jobs, and strengthen the communities in which they live and do business. LOOKING FORWARD: SUPPLY CHAIN In FY2022, Seagate will continue to focus on working with our suppliers to minimize risk of forced labor. We will also begin to engage with key suppliers to better understand their carbon footprint in order to identify opportunities for emissions reduction. Seagate will continue to confirm, including through the use of questionnaires and audits, suppliers’ compliance with the RBA Code of Conduct, responsible sourcing of materials, and adherence to any laws in the countries they conduct business in. We will also continue to advocate that this should be done within each of our suppliers’ own supply chain. Supplier Diversity We remain vigilant about child labor, forced labor, and threats to freedom of association within our supply chain. The highest risk of forced labor in our supply chain is where foreign labor is utilized; suppliers in China, Thailand, and Malaysia pose the highest risk. Our training on forced labor has been focused on suppliers in these countries over the past four years. Based on supplier VAP audits, child labor and young workers exposed to hazardous work have not been identified as a serious concern in our supply chain. However, various Non-Governmental Organizations (NGOs) report that student workers in the China supply chain represent an area of possible concern for the region. Our audit results have not identified any geographies of concern for freedom of association and collective bargaining in FY2021. Most of the findings in this area are related to suppliers not having a policy/procedure on the right of peaceful assembly.

Slide 68 — Business Continuity

Business Continuity Individuals and companies alike face the complexity and unpredictability of the world each day—and Seagate is no different in facing the innumerable risks and threats to our business. We are committed to investing and protecting our operations and supporting the community from any foreseeable threats by aligning our business continuity practices with the ISO 22301 standard. The Seagate Business Continuity Policy captures this commitment. 10 Such business challenges should not be disruptive to our customers and stakeholders. Accordingly, Seagate continued to mature our Business Continuity Management System (BCMS) throughout FY2021 to manage and mitigate the various known risks and threats to our business. Our BCMS encompasses four pillars of planning—Business Continuity Planning, Incident Management, Crisis Management, and Supply Chain Risk Management with Enterprise Risk Management Program oversight—and complies with the ISO 22301 Management System. In FY2021, Seagate transitioned our business continuity planning practices from those required in the initial release of the 2012 standard to the requirements in the second edition, ISO 22301:2019. To ensure compliance with the 2019 standard requirements and to enable continuous improvement, we continued to utilize a Business Continuity Performance Scorecard for both our HDD and component sites, as well as design centers across the enterprise, and expanded our products scope to include our Systems products. Our HDD manufacturing sites in China and Thailand were audited in CY2020 and maintained their ISO 22301:2012 certifications. In addition, in FY2021 our supply chain risk management program continued to proactively monitor supplier risk by enabling global event alerting and completing assessments of our critical suppliers. Our enterprise business continuity software remains our central repository for all business continuity documents and assessments, with both systems continuing to align with our document management practices and the requirements of ISO 22301:2019. 134 FY2021 Global Citizenship Annual Report FY2021 Global Citizenship Annual Report 135

Slide 69 — Enabling Effective Supply Chain Risk Management Through Technology

BUSINESS CONTINUIT Y BUSINESS CONTINUIT Y LOOKING FORWARD: BUSINESS CONTINUITY MANAGEMENT SYSTEM In FY2022, Seagate will continue to extend and exercise our Business Continuity Management System using the requirements set forth by ISO 22301:2019, recertifying our HDD sites in China and Thailand to ISO 22301:2019 and continuing to mitigate any potential COVID-19 impacts to ensure an effective business continuity response. Additionally, by applying our COVID-19 learnings, we will extend our Seagate BCMS through an expanded business continuity planning scope including risk mitigation and targeted action improvements related to climate change. Build out of our mitigation database will continue to allow for effective management of supplier-related risk mitigation plans. Our supply chain mapping efforts will continue to expand as well, including surveying our Tier 2 suppliers (our suppliers’ suppliers). The challenges many organizations experience today in the global supply chain are unprecedented. The dynamic situation that COVID-19 has and continues to present, as well as challenges to those unrelated to COVID-19 contribute to the supply chain disruptions we see today. At Seagate, our solution to effectively manage supply chain risk and potential supply chain disruptions is two-fold: 1) identify and assess suppliers and their capabilities, then 2) proactively mitigate and monitor any risk associated to our partner network. This approach is aided and enhanced by using carefully selected technology and tools that allow the organization to support transparent, trusting partnerships through an accessible, collaborative platform. This has given Seagate the ability to address key business risks, execute short and long-term solutions, and achieve end-to-end visibility, enabling a secure, robust global supply chain base and supply chain risk management program. Utilizing Technology to Enable Trusting Supply Chain Partnerships In FY2020, Seagate undertook a large effort to assess Seagate’s suppliers’ business continuity capabilities. We took this first step, utilizing a collaborative approach in a single digital supply chain management environment that has allowed us to stay connected to our partners and manage potentially impactful events as they arise and proactively mitigate before they occur. During FY2021, Seagate continued to mature our supply chain management strategies by improving our business CASE STUDY Enabling Effective Supply Chain Risk Management Through Technology processes that directly affect the way we manage the risks from our suppliers’ business continuity capabilities in our supply chain technology environment. Increasing Visibility into Our Supply Chain Assessing our suppliers’ business continuity capabilities is the first prong in our two-pronged approach. In FY2021, we expanded our efforts to gain insight into our diverse supply chain utilizing our Supply Chain Risk Management software, which has allowed Seagate to manage the complexity of our global supply chain by increasing visibility into our extended supply chain ecosystem, enabling the management of risk associated with our supplier network. Managing Vulnerabilities and Mitigating Risk Within Our Supply Chain Increasing the visibility into our supply chain using a reliable platform has been a critical step in securing a trusted space between Seagate and suppliers. It has created real-time transparency to effectively manage the risks related to the complexity and potential vulnerabilities within our supply chain base. As a result, Seagate has been able to identify, analyze, and assess the data collected from the Supply Chain Risk Management platform to drive consistency and enable effective decision-making to mitigate risk and make key business decisions. 136 FY2021 Global Citizenship Annual Report FY2021 Global Citizenship Annual Report 137

We identify and select stakeholders through a mapping exercise that indicates the level of engagement appropriate for each stakeholder. Criteria for selection include past engagement with Seagate, collaboration with industry associations such as the RBA, and publishers of industry reports. Below are three examples of stakeholder engagement. Global Citizenship Each year, we solicit feedback from customers and business partners to help shape our Global Citizenship program. We openly share detailed information about our environmental performance and greenhouse gas emissions to help the electronics industry reduce its environmental impact. Inputs from stakeholders help ensure we have a best-in-class program. Quality We solicit feedback on our performance, reliability, and product quality through Net Promoter Score surveys and Customer Scorecards. These reports are produced quarterly and are shared with internal teams to both celebrate successes and focus on areas for improvement. Business and Social Trends Each year, Seagate meets with investors, governments, NGOs, local communities, and other stakeholder members to gather perspectives that could affect our success as a business and as a sustainable company. Employees at Seagate also provide input through a variety of forums, surveys, and meetings. In addition, Seagate holds a yearly Supplier Day and offers webinars, training, and more. Please see the sections on Supply Chain and Product Sustainability for more information. In FY2020, Seagate conducted a formal Materiality Assessment with both internal and external stakeholders. The assessment identified key sustainability topics. We review our sustainability framework annually. After our review in FY2021, we concluded that the assessment from FY2020 remained valid.
