Letter from Our Chair

05_WDC_Letter_ColeM.jpg

Dear Fellow Stockholders:

It is a privilege to write to you once again as Chair of WD’s Board of Directors. In our first full year as an independent, hard disk drive (“HDD”)-focused company, WD has delivered outstanding performance: strong revenue growth, significant margin expansion and accelerated free cash flow, driven by disciplined execution and surging demand for high-capacity storage in the age of AI.

A Year Focused on Execution Against Our Strategy

As AI reshapes the global technology landscape, the need to store, protect, access and scale massive volumes of data has never been greater. WD is uniquely positioned at the center of that opportunity, with deep customer relationships, a leading high-capacity HDD portfolio, a technology roadmap designed to support the next generation of cloud and AI infrastructure and a strong team of Drivers. Business momentum is building across our entire portfolio, and our management team has executed on our strategy delivering strong revenue and margins amidst exceptional demand. Our focus on leading-edge innovation has been a driver of margin expansion and recognized in our relationships with hyperscaler and enterprise customers.

As we drive durable growth, our commitment to stockholders remains central to how we operate. We continued to generate strong free cash flow throughout fiscal 2026 and returned capital to stockholders through share repurchases and quarterly dividends. We have also strengthened our balance sheet, giving us the flexibility to invest in innovation and capital-efficient growth while continuing to reward the stockholders who have placed their trust in us.

Our current business enables sharper decision-making, faster execution and stronger profitability. While WD’s significant stock price appreciation in fiscal 2026 reflects the market’s recognition of this progress, our Board remains focused on translating today’s momentum into sustained, long-term value creation.

Board Composition Matched to Our Strategic Priorities

Our Board has thoughtfully assembled the right team and skillsets to oversee execution against our long-term strategy. In May 2026, we were excited to appoint Manuvir Das, a veteran technology executive and AI infrastructure leader, to our Board. He brings deep expertise in enterprise AI, data infrastructure and cloud computing, which are increasingly critical to WD’s long-term opportunities.

We regularly evaluate Board composition and succession planning. We carefully consider the skills and experiences of both new and current directors to promote alignment with our long-term strategy, risk profile and evolving market opportunities. I am proud to serve alongside such a distinguished Board committed to driving sustainable, long-term success for our stockholders in this exciting era for WD.

Western Digital2026 Proxy Statement

Strong Governance as a Cornerstone

Our Board is committed to maintaining the highest standards of corporate governance. As WD evolves, we continue to evaluate our corporate governance practices to foster thoughtful and comprehensive oversight. In 2026, our Board approved higher stock ownership thresholds for our Executive Leadership Team and Board effective July 2026. Throughout fiscal 2026, we continued our annual stockholder engagement program. Stockholder feedback remains a key input in our Board’s decision-making and helps ensure that our policies and practices remain aligned with investor expectations. Additionally, we remain focused on a compensation framework that supports both our immediate priorities and our long-term objectives, with a clear focus on driving stockholder value creation. Our executive compensation program is designed to attract and retain best-in-class talent, drive execution of our strategy and closely align pay outcomes with performance.

Commitment to Sustainability Leadership

We believe in leading by example and remain dedicated to operating responsibly by upholding integrity, accountability and transparency in everything we do. As AI infrastructure scales globally, we are closely overseeing material sustainability factors related to our business, such as energy demand, supply chain emissions, responsible sourcing and material use.
Our commitment to sustainability remains constant, and we are proud of our continued progress in driving measurable results.

We Ask for Your Support

We are honored to serve you, our stockholders, during this exciting chapter for WD. Fiscal 2026 has demonstrated the power of a focused company executing against a clear, durable demand opportunity. We thank you for your trust, engagement and investment. We welcome your input and ask for your support for each of the ballot items.

Sincerely,

Cautionary Note Regarding Forward-Looking Statements

This Proxy Statement contains forward-looking statements within the meaning of the federal securities laws. Any statements that do not relate to historical or current facts or matters are forward-looking statements. You can identify some of the forward-looking statements by the use of forward-looking words, such as “may,” “will,” “could,” “would,” “project,” “believe,” “anticipate,” “expect,” “estimate,” “continue,” “potential,” “plan,” “forecast,” and the like, or the use of future tense. Statements concerning current conditions may also be forward-looking if they imply a continuation of current conditions. Examples of forward-looking statements include, but are not limited to, statements concerning our business strategy and strategic priorities, our ability to execute our strategy, our future financial performance, our plans for our corporate responsibility and sustainability program, including our emissions reduction targets, renewable energy, waste and water use goals, and our policies and reporting in the area of human rights and inclusion efforts. These forward-looking statements are based on management’s current expectations as of the date of this Proxy Statement and are subject to a number of risks, uncertainties and other factors that could cause actual results to differ materially from those expressed or implied in the forward-looking statements. These risks and uncertainties include, but are not limited to: concentration of revenue in our Cloud end market and among our top customers; our development and introduction of products based on new technologies and expansion into new data storage markets; our dependence on a limited number of qualified suppliers; difficulties or delays in manufacturing or other supply chain disruptions; the impact of long-term agreements; product defects; hiring and retention of key employees; risks associated with strategic initiatives, restructurings, acquisitions, divestitures, mergers, joint ventures and our strategic relationships; adverse global or regional conditions, including new or additional tariffs or trade restrictions, inflation, increases in interest rates and an economic recession; volatility in demand for our products; the competitive environment, including actions by our competitors and the impact of competitive products and pricing; risks associated with our use of artificial intelligence; compromise, damage or interruption from cybersecurity incidents or other data or system security risks; our debt and other financial obligations; changes in tax laws or unanticipated tax liabilities; any decisions to reduce or discontinue paying cash dividends or repurchasing shares of our common stock; fluctuations in currency exchange rates in connection with our international operations; risks associated with compliance with changing legal and regulatory requirements and the outcome of legal proceedings; risks associated with our goals relating to sustainability matters, including our ability to meet our greenhouse gas emissions reduction and other sustainability goals; our reliance on intellectual property and other proprietary information; and other risks and uncertainties listed in our filings with the Securities and Exchange Commission (the “SEC”), including our Annual Report on Form 10-K filed with the SEC on August 14, 2026 (the “2026 Annual Report on Form 10-K”), to which your attention is directed. You should not place undue reliance on these forward-looking statements, which speak only as of the date hereof, and we do not intend, and undertake no obligation, to update or revise these forward-looking statements to reflect new information or events, except as required by law. Furthermore, certain statements in this Proxy Statement, particularly pertaining to our sustainability performance, goals and initiatives, are subject to additional risks and uncertainties, including regarding: gathering and verification of information and related methodological considerations; our ability to implement various initiatives under expected timeframes, cost and complexity; our dependency on third parties to provide certain information and to comply with applicable laws and policies; our reference to various reporting standards and frameworks (including standards for the measurement of underlying data), which continue to evolve; and other unforeseen events or conditions. These factors, as well as others, may cause results to differ materially and adversely from those expressed in any of our forward-looking statements. Additionally, we may provide information herein that is not necessarily “material” under the federal securities laws for SEC reporting purposes but that is informed by various standards and frameworks (including standards for the measurement of underlying data) and the interest of various stakeholders. However, we cannot guarantee strict adherence to framework recommendations and much of this information is subject to assumptions, estimates or third-party information that is still evolving and subject to change, and our disclosures based on these frameworks may change due to revisions in framework requirements, availability of information, changes in our business or applicable governmental policy, or other factors, some of which may be beyond our control.

Year-Round Stockholder Engagement

We have a regular and long-standing practice of maintaining dialogue with our stockholders through our Board-led stockholder engagement program. We value our stockholders’ feedback and have relied on our ongoing engagement program to solicit, identify and understand stockholder perspectives and feedback on our strategy, Board refreshment and composition, executive compensation, sustainability and other areas of investor focus. In fiscal 2026, we reached out to stockholders representing approximately 65% of shares outstanding and conducted calls with stockholders representing approximately 32% of shares outstanding, including separate discussions with both the passive and active investment teams of certain investors. Tunç Doluca, Chair of the Compensation and Talent Committee, led a majority of the engagements. Stockholder feedback is shared regularly with our Board and serves as a critical input in our Board’s deliberations and decision-making process. Please see the section entitled “Corporate Governance Matters—Stockholder Engagement” on page 28 for a description of the topics discussed and stockholder feedback during our 2026 stockholder engagement.

Corporate Responsibility and Sustainability

We incorporate sustainability into our business strategy and operations to support long-term value creation. Through environmental stewardship, stakeholder empowerment and responsible business practices, we drive sustainable data storage technologies that deliver meaningful progress toward a responsible AI infrastructure. The Governance Committee oversees our corporate responsibility and sustainability policies and programs consistent with its charter.

Environmental Stewardship. We furthered our commitment to helping protect the environment and meeting customer needs by delivering on robust environmental targets and driving innovation, accountability, and partnerships for systemic impact. In fiscal 2025, we expanded our environmental targets to include reducing direct material emissions, achieved 66% carbon-free energy across our global operations and reduced customer use-phase emissions per petabyte by 31% against our fiscal 2020 baseline. In addition, we collaborated with stakeholders to reduce environmental impacts across our ecosystem and increase circularity to reduce raw materials extraction, enabled in part by our Advanced Recovery and Rare Earth Material Capture program.

Stakeholder Empowerment. We work to empower stakeholders across our value chain, from our workforce to customers and supply chain partners to communities where we operate. In fiscal 2025, we launched a new people strategy to support Workforce of the Future in our Global Operations organizations, improved our metrics on lost time incident rate (LTIR), and engaged 100% of in-scope suppliers for material sustainability issues.

Responsible Business. In fiscal 2025, we implemented an AI Policy, committing to responsible, ethical and secure development, deployment and usage of AI, and achieved a 100% completion rate for our annual online ethics and compliance training. In fiscal 2026, we were named one of the World’s Most Ethical Companies by Ethisphere for the eighth year in a row.

PROPOSAL 1
ELECTION OF DIRECTORS

We are asking our stockholders to elect nine directors to our Board of Directors at the 2026 annual meeting of stockholders. Defining attributes of our Board include:

lAll directors are elected annually by a simple majority of votes cast

lActive Board refreshment resulting in three new independent directors being appointed in the past two years

lIndependent Board leadership, with an independent Chair of the Board separate from our CEO

lSkills and experience of directors aligned to business strategy and key areas of risk oversight

lEight of nine director nominees are independent

02_WDC_Proposal_checkmark.jpg

Our Board of Directors recommends a vote FOR each of the nine director nominees named in this Proxy Statement

Our Board of Directors is presenting nine nominees for election as directors at our 2026 annual meeting of stockholders (“Annual Meeting”). Each of the nominees is currently a member of our Board and, other than Mr. Das, who joined our Board in May 2026, was elected to our Board by our stockholders at our 2025 annual meeting of stockholders (the “2025 Annual Meeting”). Each director elected at the Annual Meeting will serve until our 2027 annual meeting of stockholders (the “2027 Annual Meeting”) and until a successor is duly elected and qualified or until the director’s earlier resignation.

Each of the nominees has consented to be named in this Proxy Statement and to serve as a director if elected. If any nominee is unable or unwilling for good cause to stand for election or serve as a director if elected, the persons named as proxies may vote for a substitute nominee designated by our existing Board of Directors, or our Board may choose to reduce its size.

Vote Required for Approval

Each director nominee will be elected as a director if the nominee receives the affirmative vote of a majority of the votes cast with respect to his or her election (in other words, the number of votes “FOR” a director must exceed the number of votes cast “AGAINST” that director). You may vote FOR, AGAINST or ABSTAIN with respect to each director nominee. Proxies received by our Board of Directors will be voted FOR each director nominee unless specified otherwise.

Under our Bylaws, any incumbent director who fails to be elected must offer to tender his or her resignation to our Board. If the director conditions his or her resignation on acceptance by our Board, the Governance Committee will then make a recommendation to our Board on whether to accept or reject the resignation or whether other action should be taken. Our Board will act on the resignation and publicly disclose and explain its decision within 90 days from the date the election results are certified. The director who tenders his or her resignation will not participate in our Board’s or the committee’s decision.

Director Independence

Our Board of Directors has reviewed and discussed information provided by the directors and our company regarding each director’s business and personal activities, as well as those of the director’s immediate family members, as they may relate to our company or our management. The purpose of this review is to determine whether there are any transactions or relationships that would be inconsistent with a determination that a director is independent under the listing standards of the Nasdaq Stock Market. Based on its review, our Board has affirmatively determined that, except for serving as a member of our Board, none of our current non-employee directors (Messrs. Cole, Das, Doluca, Kiddoo or Massengill, or Mses. Alexy, Oulman or Streeter) has any relationship that, in the opinion of our Board, would interfere with such director’s exercise of independent judgment in carrying out his or her responsibilities as a director, and that each such director qualifies as “independent” as defined by the listing standards of the Nasdaq Stock Market. Mr. Tan is currently a full-time, executive-level employee of our company and, therefore, is not “independent” as defined by the listing standards of the Nasdaq Stock Market.

14293651165859

Director Meeting Attendance

During fiscal 2026, our Board of Directors met eight times. Each of the directors who served during fiscal 2026 attended 75% or more of the aggregate number of Board meetings and meetings of the Board committees on which he or she served during fiscal 2026, with the exception of Mr. Das, who was appointed to our Board on May 26, 2026. Mr. Das attended two of the three Board and committee meetings held during his period of service in fiscal 2026. The one meeting he did not attend was a previously scheduled Audit Committee meeting held the day following his appointment.

Our Board strongly encourages each director to attend our annual meeting of stockholders. All directors standing for election at our 2025 Annual Meeting attended the meeting.

Director Nominations and Board Refreshment

Key Director Criteria

The Governance Committee has adopted a policy regarding critical factors to be considered in selecting director nominees, which include: the nominee’s personal and professional ethics, integrity and values; the nominee’s intellect, judgment, foresight, skills, experience and achievements, all of which are viewed in the context of the overall composition of our Board of Directors; the absence of any conflict of interest or legal impediment to, or restriction on, the nominee serving as a director; having a majority of independent directors on our Board; and representation of the long-term interests of our stockholders as a whole and a diversity of backgrounds and expertise, which are most needed and beneficial to our Board and our company.

Our approach to Board composition focuses on strong qualifications and diverse perspectives to create effective oversight. By evaluating a broad slate of well-qualified candidates, we aim to build a high-performing Board that brings both excellence and a range of viewpoints to the boardroom. The Governance Committee considers the skills, expertise, experience, tenure, age, gender, backgrounds and other personal characteristics of current and prospective directors to enable us to have a broad range of perspectives represented on our Board to effectively perform its governance role and oversee the execution of our strategy.

As further detailed below, the Governance Committee annually evaluates the size and composition of our Board and assesses whether the composition appropriately aligns with our evolving business and strategic needs. Through this process, our Board, upon the recommendation of the committee, develops a list of qualifications, skills and attributes sought in director candidates. Specific director criteria evolve over time to reflect our strategic and business needs and the changing composition of our Board.

Director Nomination Process

  03_WDC_Assess.jpg 

ASSESS

Our Board of Directors, led by the Governance Committee, evaluates the size and composition of our Board at least annually, considering the evolving skills, perspectives and experience needed on our Board to perform its governance and oversight role as our business transforms and the underlying risks change over time. Among other factors, the committee considers our strategy and needs, as well as our directors’ skills, expertise, experience, tenure, age and backgrounds. After assessing these factors, our Board develops criteria for potential candidates to be additive and complementary to the overall composition of our Board. Specific director criteria evolve over time to reflect our strategic and business needs and the changing composition of our Board.

 03_WDC_Identify.jpg 

IDENTIFY

The Governance Committee is authorized to use any methods it deems appropriate for identifying candidates for membership on our Board of Directors, including considering recommendations from incumbent directors, management or stockholders and engaging the services of outside search firms to identify suitable potential director candidates. In fiscal 2026, Mr. Das was appointed to the Board. Mr. Das was recommended by the Governance Committee after an extensive search was conducted by an independent third-party search firm, and numerous candidates were considered and interviewed.

 03_WDC_Evaluate.jpg 

EVALUATE

The Governance Committee has established a process for evaluating director candidates that it follows regardless of who recommends a candidate for consideration. Through this process, the committee considers a candidate’s skills, experience, outside commitments, including service on other public company boards, and other available information regarding each candidate. For incumbent director candidates, this process includes consideration of the results of the annual Board and committee evaluations. See the section entitled “Corporate Governance Matters—Board Processes and Policies—Board and Committee Evaluations” below. Following the evaluation, the committee recommends nominees to our Board.

 03_WDC_Nominate.jpg 

NOMINATE

Our Board of Directors considers the Governance Committee’s recommended nominees, analyzes their independence and qualifications and selects nominees to be presented to our stockholders for election to our Board.

Board Refreshment

Our Board of Directors believes that periodic refreshment can bring valuable experience and fresh perspectives and is most effective when balanced with continuity to preserve institutional knowledge and company-specific expertise. Our Board seeks to achieve this balance through its director succession planning process and the director retirement policy described below. Our Board also utilizes the annual Board and individual director assessment process discussed below under “Corporate Governance Matters—Board Processes and Policies—Board and Committee Evaluations” to help inform its assessment of our Board’s composition and Board refreshment needs.

As part of our ongoing refreshment process, our Board regularly evaluates its composition to seek to align directors’ skills with our evolving business needs and support effective oversight. In applying this approach, our Board undergoes a thoughtful and deliberate process to assemble a balanced mix of skills, experience and diverse perspectives aligned with our company’s new strategic direction and evolving oversight priorities. Our Board added one new independent director, Mr. Das, to our Board in 2026. Mr. Das’s track record of driving innovation across some of the world’s leading AI, cloud and enterprise infrastructure companies supports our long-term strategy. As part of this thoughtful, ongoing approach, our Board refreshment process has resulted in three new independent directors being appointed in the past two years.

Succession Planning

Our Board of Directors is focused on ensuring that it has members with a variety of skills, expertise, experience, tenure, age and backgrounds because a broad and complementary range of perspectives is critical to effective corporate governance and oversight of the execution of our strategy. The Governance Committee’s long-range succession plan not only helps to identify and recruit new directors but also ensures a smooth transition when succession needs arise. The committee also plans for the orderly succession of our Chairs of the Board committees. Over the last two years, our Board has continued to execute its long-range succession planning strategy, resulting in the appointment of three new independent directors, a new Chair of the Board and a new Chair of the Compensation and Talent Committee, while maintaining a strong focus on aligning Board composition with our evolving strategic priorities.

Retirement Policy

To help facilitate the periodic refreshment of our Board of Directors, our Corporate Governance Guidelines provide that no director shall be nominated for re-election after the director has reached the age of 75.

Director Orientation and Education

All incoming directors participate in a director orientation program. The orientation includes in-person meetings with, and presentations by, the executive team and senior management on key topics, such as business and operations, technology, cybersecurity, governance policies and practices, finance, accounting and audit matters, enterprise risk management and our ethics and compliance program. We tailor the orientation to best meet the needs of each incoming director and solicit feedback from directors who completed the orientation to continuously improve the program. New Board members typically visit our facilities to enhance their understanding of our business and operations. When directors accept new or additional responsibilities on our Board or on committees, they are provided with additional orientation and educational opportunities on relevant topics.

Because our Board believes that ongoing director education is vital to the ability of directors to fulfill their responsibilities, we invite external subject matter experts to present to our Board throughout the year on emerging and evolving issues that may impact our long-term business strategy. The Governance Committee is involved in selecting the topics, which have included AI, geopolitical environment, macroeconomic outlook, industry trends and cybersecurity. We also encourage directors to participate in continuing director education programs, at our expense, and provide a list of external learning opportunities.

Board’s Role and Responsibilities

Risk Oversight and Compensation Risk Assessment

Board’s Role in Risk Oversight

Our management team is charged with managing risk and bringing to our Board of Directors’ attention all material risk exposures to our company. Our Board is responsible for overseeing the risk management process and exercises this risk oversight through both our full Board and its committees as further detailed below.

Our enterprise risk management (“ERM”) process is designed to facilitate the identification, assessment, management, reporting and monitoring of material risks our company may face over the short and long term and assure regular communication with our Board and its committees regarding these risks. Key risks are raised by management to the Audit Committee and the full Board. At least annually, our chief audit executive, who manages the day-to-day activities of our ERM program, reports to our Board on enterprise risk assessment under our ERM program, providing updates on key risks, status of mitigation efforts and residual risk trends. Our Board consults with outside advisors and members of management, including those involved in ERM, and has access to and periodically meets with outside advisors to help monitor trends, identify potential threats and assess our company’s risk environment. Risk areas identified in the ERM process help inform how we present the risks facing our company in the “Risk Factors” section of our 2026 Annual Report on Form 10-K, which is also reviewed with the Audit Committee.

The independence of our Board and its leadership structure strengthen our Board’s ability to oversee risk. Through the authority of our independent Chair to set Board agendas and to call and preside over Board meetings and executive sessions of the independent directors (as described under “Corporate Governance Matters—Board Structure—Board Leadership Structure” below), our leadership framework provides effective mechanisms to support our Board’s oversight responsibilities. These include requiring management to report on specific risk exposures and, when appropriate, requesting additional information or directing alternative actions in response to management’s recommendations on risk matters.

}

BOARD OF DIRECTORS

Our Board meets periodically with our chief audit executive to review our overall ERM program and policies. Throughout the year, our Board receives updates on specific risks (including emerging risks such as those posed by AI) and mitigating measures during its review of our strategy and business plan, and through reports to our Board by its respective committees and senior members of management.

Compensation Risk Assessment

Consistent with SEC disclosure requirements, we reviewed our fiscal 2026 compensation policies and practices to determine whether they encourage excessive risk taking. We concluded that our compensation programs do not create risks that are reasonably likely to have a material adverse effect on our company.

Insider Trading Policy

Our Board of Directors has adopted an Insider Trading Policy governing the purchase, sale or other dispositions of our securities by members of our Board, officers and employees of our company and its subsidiaries. We believe our Insider Trading Policy is reasonably designed to promote compliance with insider trading laws, rules and regulations, and applicable listing standards. Our Insider Trading Policy is filed as Exhibit 19.1 to our 2026 Annual Report on Form 10-K. Because our Insider Trading Policy is designed to address transactions in our company’s securities by our directors, officers and employees, our Insider Trading Policy does not govern purchases of our securities by our company.

Corporate Responsibility and Sustainability

We believe responsible and sustainable business practices support our long-term success as a company. Through environmental stewardship, stakeholder empowerment and responsible business practices, we drive sustainable data storage technologies. These practices help keep our communities and our environment vibrant and healthy. They also lead us to more efficient and resilient business operations, help us meet our customers’ efficiency targets, reduce risks of misconduct and legal liability, enhance the reliability of our supply chain and improve the health, well-being, engagement and productivity of our employees. We believe that being an industry leader is not just about having talented employees or innovative products. It is also about doing business the right way, every day. That is why our commitment to corporate responsibility is deeply embedded in all aspects of our business. We earned a CDP (Carbon Disclosure Project) A‑ Leadership level rating for climate in 2025 and were included in the 2026 S&P Dow Jones Best‑in‑Class Index North America, demonstrating our leading practices and trusted disclosures across environmental, social and governance pillars.

Oversight by Our Board of Directors

Our Board of Directors is focused on setting the tone for sound corporate responsibility in all aspects of our business. The Governance Committee is responsible for assisting our Board in overseeing the development and maintenance of our corporate responsibility and sustainability policies, practices and programs, including our public sustainability reporting. The committee has specific responsibility for periodically reviewing our policies and practices related to human rights, environmental and climate change, political and lobbying activities and other topics designated by our Board from time to time. The committee receives updates from our sustainability group and management regularly, including progress towards our sustainability initiatives or established targets or goals, and reviews trends, priorities and implementation of new sustainability initiatives.

The Audit Committee is responsible for reviewing the implementation of legal or regulatory requirements regarding public disclosure of topics covered by our corporate responsibility and sustainability programs and management’s controls and procedures with respect to these disclosures. The committee also oversees our ERM process, which incorporates climate-related risk identification, assessment and management.

In addition, the Compensation and Talent Committee periodically reviews our human capital management policies and programs, including those focusing on talent attraction, engagement and retention, inclusion, rewards and other topics as may be designated by our Board from time to time.

Chief Executive Officer Evaluation and Succession Planning

Evaluation

The Compensation and Talent Committee reviews and approves our CEO’s goals and objectives in concert with the full Board of Directors. The Compensation and Talent Committee Chair leads the evaluation of our CEO’s performance against those goals and objectives by capturing input from our non-employee directors, which is then discussed with our Board. Following the evaluation of our CEO’s performance, the committee determines and approves our CEO’s compensation. Our CEO’s compensation is also discussed with the full Board before it is finalized.

Succession Planning

The Compensation and Talent Committee oversees CEO and key management personnel succession planning. Directors engage with potential CEO and key management personnel successors at Board and committee meetings and in less formal settings to allow directors to personally assess candidates. Furthermore, our Board periodically reviews the overall composition of our key management personnel’s qualifications, tenure and experience to promote alignment with our strategic focus.

Emergency Succession

Our Board of Directors has also adopted an emergency CEO succession plan. The plan will become effective in the event our CEO becomes unable to perform his or her duties to minimize potential disruption or loss of continuity to our business and operations. Our emergency CEO succession plan is reviewed annually by the Governance Committee and our Board.

Stockholder Engagement

Our Board of Directors and management are committed to regular engagement with our stockholders and soliciting their views and input on important performance, executive compensation, governance, environmental, social, people strategy and other matters. Stockholder feedback is shared regularly with our Board and serves as a critical input in our Board’s deliberations and decision-making process.

lTransparency and Informed Compensation Decisions and Governance Enhancements. The Compensation and Talent and Governance Committees routinely review our executive compensation design and governance practices and policies, respectively, with an eye towards continual improvement and enhancements. Stockholder input is regularly shared with our Board, its committees and management, facilitating a dialogue that provides stockholders with transparency into our executive compensation design, compensation decisions under consideration and governance practices, and informs our company’s enhancement of those practices.

lBoard-Driven Engagement. In addition to the Governance Committee’s oversight of the stockholder engagement process and the periodic review and assessment of stockholder input, our directors also engage directly with our stockholders by periodically participating in stockholder outreach and engagement.

lYear-Round Engagement and Board Reporting. Members of our management and directors conduct outreach to stockholders throughout the year to obtain their input on key matters and keep our management and Board informed about the issues that our stockholders tell us most matter to them.

Year-Round Stockholder Engagement

04 WDC_Callout header.jpg

In fiscal 2026, as part of our regular stockholder engagement program, we contacted stockholders representing approximately 65% of our shares of common stock outstanding and conducted calls with stockholders representing approximately 32% of our shares of common stock outstanding, including separate discussions with both the passive and active investment teams of certain investors. These investors reflect various investment styles and geographies. Our Chair of the Compensation and Talent Committee, Tunç Doluca, an independent director, led a majority of these calls.

Chair of the Board

Our Board of Directors does not have a policy with respect to whether the roles of Chair of the Board and CEO should be separate and, if they are to be separate, whether our Chair of the Board should be selected from our non-employee directors or should be an employee. Our Board believes the Board’s leadership structure at any point in time should be based upon an assessment of the needs of our Board and our company at the time after considering, among other things, our business plans, strategic opportunities and succession planning priorities. Our Board also considers the views of stockholders, including as it relates to director independence, as well as corporate governance and industry trends.

We currently separate the roles of CEO and Chair of the Board, with Mr. Cole currently serving as Chair of the Board. Mr. Cole has served as Chair of the Board since fiscal 2025. Our Board believes this is the appropriate leadership for our company at this time because it permits Mr. Tan, who began serving as our CEO in February 2025, to focus on setting our strategic direction, managing performance and providing day-to-day leadership. Our Chair of the Board focuses on providing guidance to our CEO, setting the agenda for Board meetings and other responsibilities as described below. Our Board also believes that the separation of our CEO and Chair of the Board roles assists our Board in providing robust discussion and evaluation of strategic goals and objectives. We believe that Mr. Cole is best suited for the Chair of the Board position based on his strong leadership skills, extensive experience in the technology industry, public company experience and many years of building strong relationships on our Board.

Executive Sessions

All members of our Board of Directors, other than our CEO, are independent. In order to assure that our independent directors are not inappropriately influenced by management, the independent directors meet without management in executive sessions led by our independent Chair of the Board in conjunction with each regularly scheduled meeting of our Board, and otherwise as deemed necessary by our Chair of the Board or our other independent directors. At these executive sessions, our independent directors review, among other things, our strategy, financial performance, management effectiveness and succession planning. Our Chairs of each of the Board committees also lead regular executive sessions of each of the Board committees. These executive sessions allow independent directors to speak candidly on any matter of interest, without members of management present.

Board Processes and Policies

Corporate Governance Guidelines and Code of Business Ethics

Our Board of Directors has adopted Corporate Governance Guidelines, which provide the framework for governance of our company and represent our Board’s current views with respect to selected corporate governance issues considered to be of significance to stockholders, including:

lDirector nomination procedures and qualifications

lDirector independence

lPolicies related to board refreshment and limitations on other board service

lDirector orientation and continuing education

lAnnual performance evaluations of our Board and committees

lSuccession planning and management development

lThe appointment, role and responsibilities of a Lead Independent Director

Our Board of Directors has also adopted a Code of Business Ethics that applies to all our directors, employees and officers. The current versions of the Corporate Governance Guidelines and the Code of Business Ethics are available on our website under “Leadership & Governance” at investor.wdc.com.

We intend to promptly disclose future amendments to certain provisions of the Code of Business Ethics, or waivers of such provisions granted to executive officers and directors, on our website under “Leadership & Governance” at investor.wdc.com, to the extent required by applicable rules and regulations of the SEC or the Nasdaq Stock Market.

Outside Board Policies

Our Board of Directors encourages directors to limit the number of other boards on which they serve to ensure that they are able to devote sufficient time and effort to properly discharge their duties and responsibilities as a member of our Board. In determining the appropriate number of outside directorships, directors should consider potential board attendance, participation and effectiveness on these boards. The table below summarizes the limits on the number of outside directorships under our overboarding policy set forth in our Corporate Governance Guidelines.

04_WDC_Notice_line.jpg

Directors

A director may not simultaneously serve on the boards of more than 5 public companies (including Western Digital)

CEO

Our CEO may not simultaneously serve on the boards of more than 2 public companies (including Western Digital)

All directors are in compliance with our overboarding policy.

Before accepting an invitation to serve on another board, a director must notify our Chair of the Board and our Chair of the Governance Committee. The Governance Committee reviews whether the position would affect the director’s ability to serve on our Board (including potential conflicts of interest, independence, related person transactions and time commitments). The Governance Committee reviews outside directorship positions and other time commitments annually as part of its review of director nominees and reviews the overboarding policy annually as part of its review of our Corporate Governance Guidelines. In fiscal 2026, the Governance Committee adopted an overboarding policy limiting Executive Leadership Team members at the Senior Vice President level or above to service on no more than one public company board.

Communicating with Directors

Our Board of Directors provides a process for stockholders to send communications to our Board or to individual directors or groups of directors. In addition, interested parties may communicate with our Chair of the Board or with our independent directors as a group. Our Board recommends that stockholders and other interested parties initiate any communications with our Board (or individual directors or groups of directors) in writing. These communications should be sent by mail to our Secretary (please see page 82 for contact information). The name of any specific intended Board recipient or recipients should be clearly noted in the communication (including whether the communication is intended only for our non-employee Chair of the Board or our non-employee directors as a group). Our Board has instructed our Secretary to forward such correspondence to the intended recipients unless such correspondence is purely commercial or frivolous in nature (such as spam), or otherwise obviously inappropriate for consideration.

Transactions with Related Persons

Policies and Procedures for Approval of Related Person Transactions

Our Board of Directors has adopted a written Related Person Transactions Policy. The purpose of this policy is to describe the procedures used to identify, review, approve and disclose, if necessary, any transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) in which: (i) we were, are or will be a participant; (ii) the aggregate amount involved exceeds or is expected to exceed $120,000 in any fiscal year; and (iii) a related person has or will have a direct or indirect material interest. For purposes of the policy, a related person is: (i) any person who is, or at any time since the beginning of our last fiscal year was, one of our directors or executive officers or a nominee to become a director; (ii) any person who is known to be the beneficial owner of more than 5% of our common stock (or any other class of voting securities); or (iii) any immediate family member of any of the foregoing persons.

Under the policy, once a related person transaction has been identified, the Audit Committee must review the transaction for approval or ratification. In determining whether to approve or ratify a related person transaction, the committee is to consider all relevant facts and circumstances of the related person transaction available to the committee. The committee may approve only those related person transactions that are in, or not inconsistent with, our best interests and the best interests of our stockholders, as the committee determines in good faith. No member of the committee will participate in any consideration of a related party transaction with respect to which that member or any member of his or her immediate family is a related person.

Certain Transactions with Related Persons

We have not had any related person transaction since the beginning of fiscal 2026.

Director Compensation

Fiscal 2026 Director Compensation Program for Non-Employee Directors

We believe that it is important to attract and retain exceptional and experienced directors who understand our business, and to offer compensation opportunities that further align the interests of our non-employee directors with those of our stockholders. The Compensation and Talent Committee, with the assistance of its independent compensation consultant, regularly reviews our non-employee director compensation and market trends in director compensation (including non-employee director compensation practices at a group of peer companies) and evaluates the competitiveness and reasonableness of the compensation program considering general trends and practices. The committee makes recommendations based on such review to our Board of Directors, which determines whether any changes should be made to our non-employee director compensation program.

We established a compensation program for fiscal 2026 for each of our non-employee directors that generally consisted of a combination of annual cash retainers and restricted stock units (“RSUs”). As a part of its most recent review of the non-employee director compensation program, the Compensation and Talent Committee reviewed an analysis of competitive market data and determined that our non-employee director compensation was near the median of our peers in terms of the average total direct compensation amount.

The following section describes the elements and other features of our director compensation program for fiscal 2026 for non-employee directors. We did not make any changes to the program for fiscal 2026 as compared to the fiscal 2025 director compensation program and there are currently no planned changes to the non-employee director compensation program for fiscal 2027.

Non-Employee Director Cash Retainer Fees

Cash retainer fees are paid to our non-employee directors based on Board and committee service from annual meeting to annual meeting and are paid in a lump sum immediately following the annual meeting marking the start of the year. The following table sets forth the schedule of annual cash retainer and committee membership fees for our non-employee directors for fiscal 2026.

Type of FeeCurrent Annual Fee
($)
Annual Retainer85,000 
Additional Non-Employee Chair of the Board Retainer100,000 
Additional Committee Member Retainers:
Audit Committee15,000

Governance Committee10,000 
Additional Committee Chair Retainers:
Audit Committee25,000 
Compensation and Talent Committee22,500 
Governance Committee15,000 

A non-employee director serving as Chair of a Board committee receives both the Additional Committee Chair Retainer and the Additional Committee Member Retainer for that committee. Non-employee directors who are appointed to our Board, a Board committee, or to one of our Chair positions noted above during the year are paid a pro rata amount of the annual retainer fees for that position based on service to be rendered for the remaining part of the year after appointment.

Non-employee directors do not receive a separate fee for each Board or committee meeting they attend. We reimburse our non-employee directors for reasonable out-of-pocket expenses incurred to attend each Board or committee meeting.

Non-Employee Director Equity Awards

Under our Non-Employee Director Restricted Stock Unit Grant Program, each of our non-employee directors automatically received for fiscal 2026 an award of RSUs equal in value to $240,000 (or, in the case of our non-employee director serving as Chair of the Board, $290,000). Non-employee directors receive the awards immediately following the annual meeting of stockholders if he or she has been re-elected as a director at that meeting. In the case of a non-employee director who is newly elected or appointed after the date of the annual meeting, we grant a prorated award of RSUs for the year in which he or she is elected or appointed.

The RSU awards granted in fiscal 2026 vest 100% upon the earlier of: (i) the first anniversary of the grant date; and (ii) immediately prior to the first annual meeting of stockholders held after the grant date.

Deferred Compensation Plan for Non-Employee Directors

We permit each non-employee director to defer payment of up to 80% of his or her annual cash compensation in accordance with our Deferred Compensation Plan. We also permit non-employee directors to defer payment of any RSUs awarded under our Non-Employee Director Restricted Stock Unit Grant Program beyond the vesting date of the award. RSUs and other amounts deferred in cash by a director are generally credited and payable in the same manner as amounts deferred by our executive officers and other participants in our Deferred Compensation Plan as further described in the “Fiscal 2026 Non-Qualified Deferred Compensation Table.”

Director Compensation Table for Fiscal 2026

The table below summarizes the compensation for fiscal 2026 for each of our non-employee directors serving on our Board of Directors in fiscal 2026. Mr. Tan was a named executive officer for fiscal 2026 and did not receive any additional compensation for his service as a director during fiscal 2026. Information regarding his compensation for fiscal 2026 is presented in the “Fiscal 2024-2026 Summary Compensation Table” and the related explanatory tables.

Mr. Das was appointed to our Board on May 26, 2026, and upon such appointment, received a prorated grant of 772 RSUs, with a grant date fair value of $405,030.

(3)Mr. Massengill elected to defer 20% of his cash compensation earned in calendar year 2025 and 100% of his fiscal 2026 RSU award.

Director Stock Ownership Guidelines

Under our executive and director stock ownership guidelines, which became effective in July 2026, directors must retain 50% of shares acquired through vesting of equity awards unless they own eligible securities with a market value equal to at least five times the annual base cash retainer. Eligible securities include shares of our common stock, RSUs, deferred stock units and common stock beneficially owned by the director by virtue of being held in a trust or through a nominee, and common stock held by the director’s immediate family residing in the same household. Shares the director has a right to acquire through the exercise of stock options (whether or not vested) do not count towards the stock ownership requirement. Directors have five years from the later of July 2026 or the date first appointed as a non-employee director to achieve compliance.

Elements of Our Fiscal 2026 Executive Compensation Program

We emphasize variable, at-risk compensation in alignment with our focus on operating excellence and our belief that executives’ compensation opportunities and outcomes should reflect our performance and align with stockholder value creation. The key components of our executive compensation program are summarized below.

Our fiscal 2026 equity awards were comprised of 50% performance stock units (“PSUs”) (60% for our CEO) and 50% RSUs (40% for our CEO), consistent with our past equity award structure and our commitment to prioritize performance-based pay to closely align executive incentives with company and stockholder outcomes. More than 90% of our CEO and 80% of our other NEO annual compensation was performance based and at-risk.

Executive Compensation Philosophy, Objectives and Process

The summary below provides the key objectives of our executive compensation program:

04_WDC_Notice_line.jpg

Attract, retain and motivate premier talent necessary to create growth and drive financial, operational and market performance.

Provide competitive target compensation relative to the technology industry in which we compete for business and talent.

Encourage accountability by tying a substantial portion of each executive officer’s target total direct compensation opportunity to individual, corporate and market-based performance objectives that we expect to create long-term value for our stockholders.

Pay for performance by providing a substantial portion of compensation in the form of “at-risk,” variable incentive compensation awards that reward superior individual, corporate and market-based performance and that reduce pay for underperformance.

Align the interests of our executive officers with our stockholders through our pay-for-performance compensation design and by granting long-term equity awards that include multi-year performance or service vesting requirements.

Process for Determining Executive Compensation

The Compensation and Talent Committee reviews and determines compensation for our executive officers. The committee reviews the performance and compensation of our executive officers on an annual basis and at the time of hiring, promotion or other change in responsibilities. The committee’s annual review typically occurs near the end of the prior fiscal year and beginning of the new fiscal year.

In determining our fiscal 2026 executive compensation program design and the actual pay positioning for our executive officers, including each named executive officer, the committee’s executive compensation decisions were informed by several factors, including:

04_WDC_Notice_line.jpg

EXTERNAL AND INTERNAL FACTORS

lOur compensation philosophy and objectives

lOur pay positioning relative to our compensation peer group and select broad compensation survey market data

lThe executive officer’s role, experience, scope of responsibility, past performance and expected future contributions

lInternal pay equity

lOur retention objectives

lSuccession planning

lCurrent and historical company performance and strategic and financial goals, including the impact of the separation of our flash business

lMarket performance and general economic conditions

COMPENSATION CONSULTANT

lA competitive market analysis prepared by the committee’s independent compensation consultant based on market data drawn from the compensation peer group and select broad compensation surveys

04_WDC0_Management_Line.jpg

MANAGEMENT

lOur CEO’s recommendations for our other executive officers (not including himself) based on an evaluation of their individual performance

lOur CFO’s input on the financial targets for our performance-based incentive compensation program, data regarding the impact of the program on our financial results and actual results against our pre-established performance targets

lInternal and external compensation data provided by our Chief Human Resources Officer and other staff

04_WDC0_Management_Line.jpg

STOCKHOLDERS

lFeedback received during our annual stockholder outreach and engagement efforts

The Compensation and Talent Committee engaged Compensia, Inc. (“Compensia”) as its independent compensation consultant in fiscal 2026. Compensia reported directly to the committee and communicated with management to gather information and review management proposals as needed. Compensia attended all regularly scheduled meetings of the committee during fiscal 2026 and its responsibilities generally included:

lReviewing our executive compensation program and advising on program design considerations, including the performance metrics used in our incentive compensation program

lReviewing our director compensation program design and providing a competitive market analysis on pay levels for the non-employee members of our Board of Directors

lProviding recommendations regarding the composition of our compensation peer group, including advising on the characteristics and comparability of individual peer companies

lPreparing a competitive market analysis based on data drawn from our compensation peer group and selected broad compensation surveys

lProviding information on compensation trends and regulatory developments, reviewing our executive compensation policies and practices and providing assistance with our executive compensation-related disclosures

lAdvising on other ad hoc compensation-related matters

The Compensation and Talent Committee assessed the independence of Compensia pursuant to applicable rules and regulations of the SEC and the Nasdaq Stock Market and concluded that the engagement of Compensia did not raise any conflicts of interest during fiscal 2026 and currently does not raise any conflicts of interest.

Comparative Market Data

The Compensation and Talent Committee selects companies for and approves the composition of our compensation peer group, reevaluating the composition of this group on an annual basis with the support of its independent compensation consultant.

For fiscal 2026, our independent compensation consultant prepared a competitive market analysis of executive compensation practices for review by the Compensation and Talent Committee. In addition to market data drawn from the companies in the compensation peer group, additional market data was collected from the Radford Global Compensation Database, an independently published survey. The survey data was filtered to screen for companies in our compensation peer group that participate in the survey and, for executive roles in which such survey screen resulted in insufficient data, a broader screen of technology companies as adjusted for revenue size was used. With input from our independent compensation consultant, the committee considered the analysis of this market data and industry practices during its annual review of the competitiveness of our compensation levels and the appropriate mix of compensation elements for our named executive officers. This competitive market analysis provided the committee with a reference point for its deliberations and served as one of several factors that it used to make compensation decisions as outlined above.

Compensation Peer Group

For fiscal 2026 compensation decisions and incentive program design, the Compensation and Talent Committee selected a peer group consisting of technology companies that compete with us for talent and are comparable in size (primarily by revenue) and business profile. Like us, many companies included in our compensation peer group are included in the Dow Jones U.S. Technology Hardware & Equipment Index.

In selecting companies for our compensation peer group, the Compensation and Talent Committee focused primarily on industry, competitive talent market and revenue size. Revenue is a commonly used proxy for organizational size and complexity and is typically stable from year-to-year, making it a valuable measure when selecting peers for executive compensation purposes. As part of its decision process, the committee also considered other factors during its deliberations, including comparative market capitalization and profitability metrics. Following its annual review, the committee revised and approved the compensation peer group for fiscal 2026, as follows:

Companies Added: Applied Materials, Inc.; Emerson Electric Co.

Companies Removed: No companies were removed.

Amkor Technology, Inc.
Amphenol Corporation
Applied Materials, Inc.
Arista Networks, Inc.
Ciena Corporation

Consideration of Say-on-Pay Results and Stockholder Feedback

We value the opinions of our stockholders regarding our executive compensation policies and practices and regularly engage with our stockholders throughout the year. At our 2025 Annual Meeting, approximately 94% of the votes cast on our advisory say-on-pay proposal were voted in favor of our executive compensation policies and practices. As such, we did not make any further changes to our fiscal 2026 executive compensation program specifically in response to the 2025 say-on-pay advisory vote.

Fiscal 2026 STI Design and Performance

Our STI program provides our executives and other eligible employees an opportunity to share in any success that they help create by aligning annual incentive compensation with our company’s annual performance. The STI program encourages the achievement of our annual business goals and rewards attainment of those goals based on Company and individual performance as measured against achievement of those annual objectives.

Fiscal 2026 Corporate Performance

The Compensation and Talent Committee approved fiscal 2026 performance targets for the two corporate financial measures described below that incentivized our named executive officers to grow revenue and improve profitability.

When the committee approved fiscal 2026 performance targets in August 2025, the separation of our flash business had been completed in the second quarter of fiscal 2025, making fiscal 2026 our first full year operating as an independent, focused HDD company. With the separation of our flash business behind us and our go-forward operating structure fully in place, the committee returned to a single annual performance period and streamlined the STI metrics to focus on the financial measures most critical to driving stockholder value as a standalone entity. Specifically, the committee selected non-GAAP operating income (weighted 70%) and revenue (weighted 30%) as the fiscal 2026 STI metrics, emphasizing profitability and top-line growth as the primary indicators of our execution against our strategic priorities. Both metrics required meaningful improvement over fiscal 2025 results for our executive officers to achieve target performance expectations and exceeded market guidance at the time the hurdles were set.

Fiscal 2026 Individual Performance Modifier

To incentivize individual execution, leadership and ESG goals, executive fiscal 2026 STI payouts were subject to a +/-20% modifier based on individual performance. For executives other than our CEO, the individual performance and the resulting individual performance modifier percentages were approved by the Compensation and Talent Committee based on the CEO’s recommendations following an assessment of the applicable executive’s performance against his or her fiscal 2026 objectives. Although the Committee may assign individual performance modifiers of up to +20% for certain NEOs, the STI program caps total individual STI payouts at 200% of each executive’s target incentive award opportunity; accordingly, actual payouts did not exceed 200% of target for any executive, including any named executive officer.

CEO Individual Performance

Mr. Tan’s key objectives for fiscal 2026 included (i) achievement of financial targets (revenue, non-GAAP gross margin, non-GAAP operating income and non-GAAP EPS); (ii) advancing next-generation HDD product development; (iii) strengthening supply chain resiliency through strategic transactions and partnerships; (iv) driving organizational efficiency and workforce engagement; (v) maintaining and expanding relationships with key customers and investors; and (vi) advancing internal innovation.

Mr. Tan’s individual performance results were based on the Compensation and Talent Committee’s holistic assessment of performance against these key objectives for fiscal 2026. Performance on non-financial objectives was assessed qualitatively, without assigning specific weighting to any individual item. Following a careful review of our fiscal 2026 results and Mr. Tan’s contributions to these results, the committee assigned Mr. Tan a +20% individual performance modifier reflecting his exceptional performance against his key objectives. Although the committee assigned Mr. Tan a +20% individual performance modifier, the STI program caps total individual STI payouts at 200% of each executive’s target incentive award opportunity; accordingly, Mr. Tan’s total STI payout was capped at 200% of his target incentive award opportunity.

FISCAL 2026 STI PAYOUTS

The table below shows the inputs used for the calculation of the actual STI payouts for fiscal 2026 for each NEO. The actual corporate performance achievement against each of the approved corporate financial metrics was 200% of the pre-established target performance level. As a result, our named executive officers received the following payouts under our STI program:

Long-Term Incentives: Fiscal 2026 Equity Awards

Fiscal 2026 Annual LTI Awards

Our named executive officers received long-term incentive (“LTI”) awards in August 2025 consisting of a mix of PSUs and RSUs. The named executive officers’ RSU awards are scheduled to vest with respect to 25% of the award on the first anniversary of the grant date and with respect to 6.25% of the award quarterly thereafter over the subsequent three-year period. The vesting provisions of the fiscal 2026-2028 PSU awards are described below under the section entitled “Fiscal 2026-2028 PSU Awards”.

In addition, under these financial accounting standards, the grant date fair value for a multi-year PSU award where the performance metrics and related targets are approved on an annual basis for each portion of the award is not determined until the fiscal year in which the performance metrics and targets for that portion of the awards are established. The performance metrics for the fiscal 2026-2028 PSU awards are determined annually by the committee for each annual performance period. Accordingly, only the grant date fair value for the portion attributable to fiscal 2026 is reflected in the “Fiscal 2024-2026 Summary Compensation Table” and the “Grants of Plan-Based Awards Table” for this portion of the award. The total LTI target grant value in the preceding table reflects the total target award value for the entire three-year performance cycle.

Long-Term Incentives: PSU Design and Performance

Fiscal 2026-2028 PSU Awards

With respect to the fiscal 2026-2028 PSU awards, the Compensation and Talent Committee decided to retain the award design and structure of the fiscal 2025-2027 PSU awards with only one material change - substituting adjusted free cash flow(1) for the revenue performance measure used in the prior fiscal year’s award (with revenue being added as a performance metric in the fiscal 2026 STI program). Similar to the fiscal 2025-2027 PSUs, the fiscal 2026-2028 awards include annual financial metrics with annual payouts that are averaged to determine a three-year payout percentage. This payout percentage is then modified upwards or downwards based on relative TSR measured by the full three-year performance cycle. The relative TSR modifier compares our three-year TSR performance to the median company in the index based on three-year TSR performance. If our TSR performance exceeds the TSR of the median company by 50 percentage points or more, the PSU payout is modified by +10%; if our TSR performance is lower than the median company by 50 percentage points or more, the PSU payout is modified by -10%. Straight line interpolation will be used for performance between those points to determine the PSU payout modifier. In the event our absolute TSR performance is negative, the relative TSR modifier may not increase the PSU payout and can only be used to decrease such payout.

The Compensation and Talent Committee chose the S&P 500 Information Technology Index constituents for the relative TSR peer group, consistent with our prior year design, because our company is a member of the index, and because the index also includes a majority of the companies in our compensation peer group. The index also includes companies that stockholders review in comparing our relative performance and reflects input from our stockholders that they prefer that we use an industry peer set for relative TSR versus a broad-based index such as the S&P 500 Index. The committee determined that using this index provides for an objectively constituted benchmark and provides greater continuity over three-year performance cycles than our smaller compensation peer group, which periodically must be reconstituted because of mergers and acquisition activity. We review the composition of our compensation peer group and the index periodically to ensure we are using the most appropriate benchmark as our strategy and the competitive market evolves. Generally, our executive officers must remain employed through the entire three-year performance cycle to earn and vest in the awards.

Fiscal 2027 Compensation Program Changes

Following its annual review of our fiscal 2027 executive compensation program, the Compensation and Talent Committee determined that the current program design and structure are appropriately aligned with the market and our long-term strategy and require no changes at this time.

Other Program Features and Policies

Perquisites

We provide our executive officers with limited perquisites and other personal benefits, consisting principally of a $5,000 annual allowance for financial planning services (net of taxes) and, in very limited circumstances, tax gross-ups for certain payments. No tax gross-ups are awarded in connection with severance or change-in-control. Any tax gross-ups paid to our named executive officers are disclosed in our “Fiscal 2024-2026 Summary Compensation Table.”

Company policy permits our CEO to use private aircraft for non-business travel to maximize his business availability and productivity. Our CEO is required to reimburse our company for the aggregate incremental cost incurred by our company in connection with any such non-business use in excess of $250,000 per fiscal year. He is fully responsible for all personal income taxes associated with such personal usage.

401(k) Plan
Benefits

We provide retirement benefits to our executive officers and other eligible employees under the terms of our 401(k) Plan. Eligible employees may contribute up to 85% of their annual cash compensation up to a maximum amount allowed by the Internal Revenue Code, and are also eligible for any matching contributions. Our executive officers participate in our 401(k) Plan on substantially the same terms as our other participating employees. We do not maintain any defined benefit supplemental retirement plans for our executive officers.

Deferred
Compensation
Opportunities
Our executive officers and certain other key employees who are subject to U.S. federal income taxes are eligible to participate in our Deferred Compensation Plan. Participants can elect to defer certain compensation without regard to the tax code limitations applicable to tax-qualified plans. We did not make any company matching or discretionary contributions to our Deferred Compensation Plan on behalf of participants in fiscal 2026.
Severance
Protections

Outside a change in control context, we view severance protections as appropriate only in the event the employment of an executive officer is involuntarily terminated without “cause.” The Compensation and Talent Committee believes these severance payments and benefits are appropriate considering severance protections available to executive officers in the companies in our compensation peer group and are an important component of each executive officer’s overall compensation.

Change in Control
Protections

A transaction involving a change in control of our company creates uncertainty regarding the continued employment of our executive officers. To encourage our executive officers to remain employed with us during an important time when their prospects for continued employment following the transaction are often uncertain, we provide our executive officers with additional severance protections under our Change in Control Severance Plan. We also provide these severance protections to help ensure that our executive officers can objectively evaluate change in control transactions that may be in the best interests of our stockholders despite the potential negative consequences such transactions may have on them personally. Benefits under our Change in Control Severance Plan require a “double-trigger” (qualifying termination in connection with a change in control) for payment and the plan does not provide any tax gross-up payments for participants.

Please see the section entitled “—Executive Compensation Tables and Narratives—Potential Payments upon Termination or Change in Control” for a description and quantification of the potential payments that may be made to our named executive officers in connection with their termination of employment, including in the event of a change in control of our company.

Employment
Agreements

None of our executive officers is currently party to an employment agreement with us.

Compensation
Recovery
(Clawback) Policy

Our Board of Directors has adopted a compensation recovery (clawback) policy consistent with the requirements of Rule 10D-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Nasdaq listing standards, a copy of which is publicly filed with our 2026 Annual Report on Form 10-K.

Misconduct
Policies

We maintain several policies relating to employee misconduct. In the event an executive officer’s employment is terminated for cause due to their misconduct or violation of company policy, among other reasons, they will forfeit all outstanding incentives, including unearned or unvested LTI and STI awards. In addition, the executive officer would not be eligible for severance payments or benefits.

Policies Prohibiting
Hedging, Pledging
and Short Sale
or Derivative
Transactions

Our insider trading policy prohibits our executive officers (as well as our other employees and members of our Board of Directors) from engaging in hedging transactions or speculative transactions involving our company’s securities and from pledging company securities. Prohibited transactions include hedging or monetization transactions, such as prepaid variable forwards, equity swaps, collars and exchange funds that are designed to hedge or offset any decrease in the market value of our company’s securities, short sales, transactions in derivative securities, such as publicly traded options, related to our company’s securities and margining our company’s securities in a margin account or otherwise pledging company securities as collateral for a loan.

Equity Award Grant Practices

Equity awards are discretionary and are generally granted to our executive officers, including our named executive officers, in August of each year. In certain circumstances, including the hiring or promotion of an executive officer, the Compensation and Talent Committee may approve grants to be effective at other times. We do not currently grant stock options to our employees. The Compensation and Talent Committee did not take material nonpublic information into account when determining the timing and terms of equity awards in fiscal 2026, and our company does not time the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation.

Executive Stock
Ownership
Guidelines

We maintain executive stock ownership guidelines covering our executive officers, including our named executive officers, to help link the interests of our stockholders with those of our executive officers. The guidelines provide that each executive officer must achieve ownership of a number of “eligible securities” with a market value equal to the specified multiple of the officer’s base salary in effect upon the date he or she first becomes subject to the guidelines shown below.

In fiscal 2026, the Compensation and Talent Committee strengthened these guidelines by applying an ownership requirement of three times base salary to all executive officers other than our CEO, increased from the prior tiered requirements based on individual positions.

Position

Minimum Ownership Requirement

Chief Executive Officer

6 x Salary

Other Executive Officers

3 x Salary

Executive officers must achieve ownership of the required market value of shares within five years of becoming subject to the guidelines. Common stock (including shares held indirectly in a trust or by family members living in the same household), unvested RSUs, deferred stock units and common stock beneficially owned by the executive officer count towards the requirement, but PSUs and shares the officer has a right to acquire through exercising stock options (whether or not vested) are not counted. Any executive officer who has not met the applicable requirement following the compliance period must retain 50% of shares acquired through vesting of equity awards until compliance is achieved.

(1)The amounts shown reflect the aggregate grant date fair value of stock awards granted in the applicable fiscal year computed in accordance with ASC Topic 718. These amounts were calculated based on the assumptions described in Note 13 in the Notes to Consolidated Financial Statements included in our 2026 Annual Report on Form 10-K. For PSU awards, amounts include the grant date fair value of the 2026-2027 PSUs and the 2026-2028 PSUs, in each case, as related to the fiscal 2026 performance period because only the annual targets for such performance periods were established in fiscal 2026, and thus, such portions of the awards are deemed granted for financial accounting purposes during fiscal 2026. The grant date fair value of the remaining PSUs under the 2026-2027 and 2026-2028 PSU awards will be reflected in the Summary Compensation Table in future fiscal years corresponding to when the associated annual targets are established and such portions are deemed granted for financial accounting purposes.

The following amounts represent the grant date fair value of PSU awards granted to our named executive officers during fiscal 2026 assuming the probable outcome of the awards on the grant date and assuming maximum performance under the awards deemed granted during fiscal 2026. We considered the probable outcome of the awards based on the target level of performance for PSUs except for PSUs that are subject to relative TSR conditions, which were determined using a Monte Carlo simulation. As stated above, for the 2026-2027 PSUs and the 2026-2028 PSUs, the grant date fair values for the fiscal 2026 performance period of such PSUs have been included because such portions of the awards are deemed granted in fiscal 2026 for financial accounting purposes. The dollar value of the awards included in the Summary Compensation Table for the year of grant is based on the probable outcome of the awards on the grant date and do not reflect actual payouts.

These amounts were calculated based on the assumptions described in Note 13 in the Notes to Consolidated Financial Statements included in our 2026 Annual Report on Form 10-K. The grant date fair value for the PSU awards, at the probable outcome, is based on the value of our common stock on (i) August 25, 2025 for the 2026 performance period under the 2026-2027 PSUs using a Monte Carlo simulation, which resulted in a simulated award value of $85.28 per share, (ii) August 25, 2025 for the 2026 performance period under the 2026-2028 PSUs using a Monte Carlo simulation, which resulted in a simulated award value of $85.10 per share, and (iii) August 26, 2025 for the 2026 performance period under the 2026-2028 PSUs using a Monte Carlo simulation, which resulted in a simulated award value of $85.62 per share, based on certain assumptions.

(2)Represents the 2026 annual performance period portion of the PSU award granted to the named executive officer for the two-year performance period covering fiscal 2026 through 2027, subject to cliff vesting on August 21, 2027, based on our achievement of specified non-GAAP EPS and adjusted free cash flow performance goals and relative TSR modifier that correspond to specific payout percentages ranging between 0% and 220% of the target number of stock units subject to the award. Under financial accounting standards, an award is not deemed granted and the grant date fair value for a PSU award is not determined until the fiscal year in which the performance metrics are established. The performance metrics are annually determined by the Compensation and Talent Committee for each of fiscal 2026 and 2027. Accordingly, only the grant date fair value for the portion attributable to fiscal 2026 annual targets of such award is reflected.

(3)Represents the 2026 annual performance period portion of the PSU award granted to the named executive officer for the three-year performance period covering fiscal 2026 through 2028, subject to cliff vesting on August 26, 2028, based on our achievement of specified non-GAAP EPS and adjusted free cash flow performance goals and relative TSR modifier that correspond to specific payout percentages ranging between 0% and 220% of the target number of stock units subject to the award. Under financial accounting standards, an award is not deemed granted and the grant date fair value for a PSU award is not determined until the fiscal year in which the performance metrics are established. The performance metrics are annually determined by the Compensation and Talent Committee for each of fiscal years

Description of Compensation Arrangements for Named Executive Officers

Non-Equity Incentive Plan Compensation and Awards

Our named executive officers are eligible to receive cash incentive awards on an annual basis under the STI plan. See the section entitled “Executive Compensation—Compensation Discussion and Analysis” for a more detailed description of the STI plan.

Equity-Based Awards

Each RSU and PSU award reported in the “Fiscal 2026 Grants of Plan-Based Awards Table” was granted by the Compensation and Talent Committee under, and is subject to, the terms of our 2021 Long-Term Incentive Plan.

Our named executive officers are not entitled to voting rights with respect to their stock units (PSUs and RSUs). However, if we pay an ordinary cash dividend on our outstanding shares of common stock, the named executive officer will have the right to receive a dividend equivalent with respect to any unpaid stock unit (whether vested or not) held as of the record date for the dividend payment, which will not be payable until the award vests.

Additional information regarding the vesting acceleration provisions applicable to equity awards granted to our named executive officers is included in the section entitled “—Potential Payments upon Termination or Change in Control” below.

Outstanding Equity Awards at Fiscal 2026 Year-End Table

The following table presents information regarding the current holdings of stock options and stock awards (and corresponding dividend equivalents) held by each of our named executive officers as of July 3, 2026. The amount shown for the market value of the stock awards is based on the closing price of our common stock ($539) on July 2, 2026, the last trading day of fiscal 2026.

Fiscal 2026 Non-Qualified Deferred Compensation Table

We permit our named executive officers and other key employees to elect to receive a portion of their compensation reported in the “Fiscal 2024-2026 Summary Compensation Table” on a deferred basis under our Deferred Compensation Plan. Under the plan, each participant may elect to defer up to 80% of his or her eligible compensation that may be earned during the following year. Amounts may be deferred until a specified date, retirement, disability or death. Emergency hardship withdrawals are also permitted under the plan.

The following table presents information regarding the contributions to, investment earnings, distributions and total value of our named executive officers’ balances under our Deferred Compensation Plan during fiscal 2026, including as to RSUs and PSUs that vested but as to which payment was deferred until after fiscal 2026.

Potential Payments upon Termination or Change in Control

Change in Control—Termination without Cause or For Good Reason

Our named executive officers may be entitled to severance benefits under our Change in Control Severance Plan. Generally, the severance benefits are payable if we terminate the named executive officer’s employment without “cause” or the named executive officer voluntarily terminates employment for “good reason” within 12 months after a change in control.

For these purposes:

l“Change in control” generally means an acquisition by any person or group of more than one-third of our stock, certain majority changes in our Board of Directors over a period of not more than two years, mergers and similar transactions that result in a 50% or greater change in our ownership, and certain liquidations and dissolutions of our company

l“Cause” generally means the commission of certain crimes by the executive officer, the executive officer’s willful engagement in fraud or dishonest conduct, refusal or failure to perform certain duties, breach of fiduciary duty, or breach of certain other violations of company policy

l“Good reason” generally means a material diminution in the executive officer’s authority, duties or responsibilities, a material diminution in the executive officer’s base compensation, certain relocations of the executive’s employment, or a material breach by us (or our successor) with respect to our obligations under our Change in Control Severance Plan

For each of our named executive officers, the severance benefits generally consist of the following as a “Tier 1” participant:

lA lump sum payment equal to two times the sum of the executive officer’s annual base compensation plus the target STI as in effect immediately prior to the change in control or as in effect on the date of notice of termination of the executive officer’s employment with us, whichever is higher, plus any earned but not yet paid STI payments in respect of completed performance periods

l100% vesting of any unvested outstanding equity awards granted to the executive officer by us, with any performance-based equity awards as to which the applicable performance period has not ended becoming vested at the target level (or, if more favorable, as otherwise provided in the agreement providing for a change in control)

lA lump sum payment equal to the applicable COBRA premium payments for a period of 24 months following the executive officer’s termination

Involuntary Termination without Cause—No Change in Control

Our Executive Severance Plan, in conjunction with the terms and conditions of our equity awards, provides the following severance benefits to our named executive officers as Tier 1 participants in the event their employment is terminated without “cause” (generally as defined above).

lA lump sum cash payment of the executive officer’s monthly base salary multiplied by 24 months

lAny earned but not yet paid STI payments in respect of completed performance periods and a pro rata STI payment based on the number of days in the applicable performance period during which the executive officer was employed, paid out at target performance

lFor PSU awards, a prorated portion of the PSUs subject to the award will remain outstanding and vest, if at all, based on actual achievement of the performance goals over the entire performance period

lFor RSU awards, acceleration of vesting of a prorated amount of RSUs

lOutplacement services for U.S.-based executive officers at our expense for 12 months following the executive officer’s termination of employment

lA lump sum payment equal to the applicable COBRA premium payments for a period of 18 months following the executive officer’s termination

Payment of severance benefits under our Change in Control Severance Plan and Executive Severance Plan is conditioned upon the executive officer’s execution of a valid and effective release of claims. In addition, no executive officer is entitled to a duplication of benefits under our Executive Severance Plan and any other severance plan, including our Change in Control Severance Plan.

Qualified Retirement

For RSUs granted prior to the fiscal 2022 annual grant, in the event an executive officer meets certain retirement criteria, the vesting of a pro rata portion of the RSUs will accelerate. RSUs granted beginning with the fiscal 2022 annual grant no longer contained the acceleration benefit for an eligible retirement.

A pro rata portion of the target number of PSUs will remain outstanding and eligible to vest based on actual achievement of the performance goals over the performance period.

To be eligible for retirement, the executive officer must have five years of credited service with us and must also be at least age 55 at the time of retirement and his or her age plus total years of credited service must be at least 70.

Death

In the event of an executive officer’s death, the vesting of a pro rata portion of the RSUs granted prior to our fiscal 2025 grant will accelerate and a pro rata portion of the target number of PSUs will remain outstanding and eligible to vest based on actual achievement of the performance goals over the performance period. For RSUs, beginning with our fiscal 2025 annual grant, 50% of the outstanding RSUs will accelerate upon an executive officer’s death. The executive officer would also be eligible for a pro rata STI payout based on the number of days in the applicable performance period during which the executive officer was employed, subject to actual corporate performance and no individual modification.

Termination for Cause/Misconduct

In the event an executive officer’s employment is terminated for cause due to, among other reasons, the executive officer’s misconduct or violation of company policy, the executive officer will forfeit all outstanding incentives, including unearned or unvested LTI and STI awards. In addition, the executive officer would not be eligible for severance benefits.

Calculation of Potential Payments upon Termination or Change in Control

The table below presents our estimate of the benefits payable to Messrs. Tan, Sennesael, Gubbi and Shihab and Ms. Tregillis (see the table below for a summary of their actual termination benefits, as applicable), under the arrangements described above based on the following assumptions:

lQualifying termination of employment and/or change in control occurred on July 3, 2026

lThe price per share of our common stock is equal to the closing price of our common stock on July 2, 2026 ($539), the last trading day in fiscal 2026

lIn the case of a change in control, our company does not survive the change in control, and all outstanding incentive awards are cashed out and terminated in the transaction

lNot included in the table below are payments each named executive officer earned or accrued prior to termination, such as the balances under our Deferred Compensation Plan and previously vested equity and non-equity incentive awards, which are more fully described and quantified in the tables and narratives above

(1)None of our named executive officers’ equity awards will automatically vest because a change in control event occurs. The amounts shown represent the estimated value of the acceleration of outstanding equity incentive compensation under our incentive compensation plans in connection with a change in control (regardless of whether a termination of employment also occurs) assuming that the awards were to be terminated in connection with the change in control and the Compensation and Talent Committee had not provided for the assumption, substitution or other continuation of the awards.

(2)For the PSU awards, where applicable, the amounts are prorated and assume achievement at 100% of the target level of performance for the performance period or, if applicable, the credited amount.

(3)As of July 3, 2026, only Mr. Gubbi met the requirements for a “qualified retiree” with respect to certain equity awards.

(4)The amounts shown are based on the intrinsic value of the portion of the RSU award that would have accelerated as of July 3, 2026. These intrinsic values were based on the closing price of our common stock on July 2, 2026 ($539). These amounts also include accrued dividend equivalents with respect to the portion of the RSU that would have accelerated as of July 3, 2026.

(5)The amounts shown represent the target number of PSUs subject to the award that would have remained outstanding and eligible to vest in connection with the termination event and are based on the intrinsic value of those stock units as of July 3, 2026. These intrinsic values were calculated by multiplying (i) the closing price of our common stock on July 2, 2026 ($539), by (ii) the target number of PSUs or, if applicable, the credited amount, that would have remained outstanding and eligible to vest as of July 3, 2026. These amounts also include accrued dividend equivalents with respect to the portion of the PSU that would have remained outstanding and eligible to vest as of July 3, 2026.

(6)For purposes of the calculation for these amounts, expected costs have not been adjusted for any actuarial assumptions related to mortality, likelihood that the named executive officer will find other employment or discount rates for determining present value.

CEO Pay Ratio

SEC rules require us to disclose the ratio of our CEO’s annual total compensation to the annual total compensation of the “median compensated” employee of all our employees (the “Median Compensated Employee”), other than our CEO.

This pay ratio reported below is a reasonable estimate calculated in a manner consistent with SEC rules based on our payroll records and the methodology described below. Because SEC rules for identifying the Median Compensated Employee and calculating the CEO pay ratio based on the Median Compensated Employee’s annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions and to make reasonable estimates and assumptions, the CEO pay ratio reported by other companies may not be comparable to the pay ratio reported below, as other companies may have very different global workforce strategies, employment and compensation practices, and may utilize different methodologies, exclusions, estimates and assumptions in calculating and reporting their CEO pay ratio.

In identifying our Median Compensated Employee for our fiscal 2026 CEO pay ratio, we used “Target Total Cash,” which includes base salary or base wages and target cash incentives. For hourly employees, we calculated base wages based on a reasonable estimate of hours worked during fiscal 2026 and the relevant employee’s hourly wage rate as in effect on April 3, 2026. For salaried employees, we calculated base salary using the relevant employee’s annual salary level as in effect on April 3, 2026. We annualized Target Total Cash for all permanent employees who did not work the full fiscal 2026.

To identify our Median Compensated Employee for fiscal 2026, we used our global employee population effective as of April 3, 2026. As of this date, our employee population was 40,550 employees, with approximately 88% of those employees located in Asia, approximately 1% of those employees located in Europe, the Middle East and Africa and approximately 11% of those employees located in the United States. Most of our employees in Asia are employed in our factories. This total includes all regular, part-time, supplemental and temporary employees with no exclusions.

The Median Compensated Employee for fiscal 2026 was an Operator 1, Manufacturing, in Malaysia. We calculated the Median Compensated Employee’s annual total compensation in the same manner as our CEO’s total compensation is calculated and reported above in the “Fiscal 2024-2026 Summary Compensation Table.” The fiscal 2026 annual total compensation for the Median Compensated Employee was calculated at $11,787, and our CEO’s annual total compensation was $17,168,701. The resulting ratio of annual total compensation of our CEO to our Median Compensated Employee for fiscal 2026 was 1,457 to 1.

Pay Versus Performance

As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(v) of Regulation S-K under the Exchange Act, we are providing the following information about the relationship between executive “compensation actually paid” (as computed in accordance with SEC rules) and certain financial performance measures. For further information concerning our pay-for-performance philosophy and how we align executive compensation with our performance, please see the section entitled “Executive Compensation—Compensation Discussion and Analysis” beginning on page 42.

The following tables and related disclosures provide information about (i) the total compensation of our principal executive officer (“PEO”) and our non-PEO named executive officers (collectively, the “Other NEOs”) as presented in the “Fiscal 2024-2026 Summary Compensation Table” above and its equivalent table in prior years’ proxy statements; (ii) the “compensation actually paid” to our PEO and our Other NEOs, as calculated pursuant to Item 402(v) of Regulation S-K under the Exchange Act; (iii) certain financial performance measures; and (iv) the relationship between the “compensation actually paid” to those financial performance measures.

(1)Mr. Tan was appointed PEO effective February 22, 2025. David Goeckeler was our PEO from the start of fiscal 2025 through February 21, 2025, and for each of the other years presented. The Other NEOs were: (i) for fiscal 2026, Messrs. Sennesael, Gubbi, Shihab and Ms. Tregillis (ii) for fiscal 2025, Messrs. Sennesael, Gubbi, Shihab, Jabre, Bennett and Soderbery and Ms. Tregillis; (iii) for fiscal 2024 and fiscal 2023, Messrs. Jabre, Soderbery, Ray and Sivaram; and (iv) for fiscal 2022, Messrs. Jabre, Sivaram, Soderbery and Ray and Robert Eulau (our former CFO). The dollar amounts reported are the amounts reported for the PEO, or the average of the amounts reported for the Other NEOs, for each of the corresponding fiscal years in the “Total” column in our applicable Summary Compensation Table. The fiscal 2025 amount reported for Mr. Tan reflects the updated corresponding “Total” column in the “Fiscal 2024-2026 Summary Compensation Table” above.

(2)The following table describes the adjustments, each of which is prescribed by the SEC rules, to calculate the “compensation actually paid” amounts from the Summary Compensation Table for each fiscal year. The Summary Compensation Table amounts and the “compensation actually paid” amounts do not reflect the actual amount of compensation earned by or paid to our named executive officers during the applicable fiscal years, but rather are amounts determined in accordance with Item 402 of Regulation S-K under the Exchange Act. As reflected in the table below, pursuant to the applicable rules, the amounts in the “Stock Awards” column in the applicable Summary Compensation Table are subtracted from the amounts in the “Total” column and the values reflected in the table below are added or subtracted, as applicable.

(a)Equity values are calculated in accordance with FASB ASC Topic 718, and the valuation assumptions used to calculate fair values did not materially differ from those disclosed at the time of the grant. The amounts shown with respect to our Other NEOs are the average amounts for such Other NEOs, as a group.

(3)TSR is calculated by dividing (a) the sum of (i) the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and (ii) the difference between our share price at the end of each fiscal year shown and the beginning of the measurement period by (b) our share price at the beginning of the measurement period.

(4)The peer group used for this purpose is the Dow Jones U.S. Technology Hardware & Equipment Index.

(5)The dollar amounts reported represent the amount of net income reflected in our audited financial statements for the applicable fiscal year. To account for the separation of Sandisk in 2025, net income for 2025, 2024 and 2023 are reflected on a continuing operations basis with the net income attributable to Sandisk reported in discontinued operations. Net income in 2022 includes Sandisk, as separate results for Sandisk are not available for that year.

(6)The dollar amounts reported represent the amount of revenue reflected in our audited financial statements for the applicable fiscal year. To account for the separation of Sandisk in 2025, revenue for 2025, 2024 and 2023 are reflected on a continuing operations basis with the revenue attributable to Sandisk reported in discontinued operations. Revenue in 2022 includes Sandisk, as separate results for Sandisk are not available for that year.

Financial Performance Measures

As described in greater detail under “Executive Compensation—Compensation Discussion and Analysis,” our executive compensation programs reflect a pay-for-performance philosophy. The metrics that we use for both our short- and long-term incentives are selected to incentivize our named executive officers to create value for our stockholders. The most important financial performance measures used to link executive compensation actually paid to our named executive officers to our company’s performance for the most recent fiscal year, are as follows:

lAdjusted Free Cash Flow

lRevenue (the Company-Selected Measure)

lNon-GAAP EPS

lNon-GAAP Operating Income

Description of Certain Relationships between Information Presented in the Pay versus Performance Table

As described in greater detail under “Executive Compensation—Compensation Discussion and Analysis,” our executive compensation programs reflect a pay-for-performance philosophy. While we utilize several performance measures to align executive compensation with our performance, all those measures are not presented in the Pay versus Performance table. Moreover, we generally seek to incentivize long-term performance and therefore do not specifically align our performance measures with compensation that is actually paid (as computed in accordance with SEC rules) for a particular fiscal year. In accordance with SEC rules, we are providing the following descriptions of the relationships between information presented in the Pay versus Performance table.

To account for the separation of Sandisk in fiscal 2025, net income and revenue for fiscal 2025, 2024 and 2023 are reflected on a continuing operations basis with the net income and revenue attributable to Sandisk reported in discontinued operations. Net income and Revenue in fiscal 2022 includes Sandisk, as separate results for Sandisk are not available for that year.

PROPOSAL 3
RATIFICATION OF APPOINTMENT OF OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

lOur Board of Directors is seeking stockholder ratification of the Audit Committee’s appointment of KPMG LLP as our independent registered public accounting firm for fiscal 2027

lWe expect representatives of KPMG LLP to be present at the Annual Meeting, and they will have an opportunity to make a statement if they desire to do so and will be available to respond to appropriate questions

02_WDC_Proposal_checkmark.jpg

Our Board of Directors recommends a vote FOR the appointment of KPMG LLP as our independent registered public accounting firm for fiscal 2027

KPMG LLP has served as our independent auditors since 1970. The Audit Committee has again appointed KPMG LLP to serve as our independent registered public accounting firm for the fiscal year ending July 2, 2027. We are not required to submit the appointment of KPMG LLP for stockholder approval, but our Board of Directors has elected to seek ratification of the appointment of our independent registered public accounting firm by our stockholders. If holders of a majority of the shares of our common stock represented at the Annual Meeting and entitled to vote do not ratify this appointment, the committee will reconsider its appointment of KPMG LLP and will either continue to retain KPMG LLP or appoint a different firm. In addition, even if stockholders ratify the committee’s selection, the committee, in its discretion, may still appoint a different independent registered public accounting firm if it believes that such a change would be in the best interests of our company and our stockholders.

Following are the fees paid by us to KPMG LLP for fiscal 2026 and 2025:

Description of Professional Service

The Audit Committee has adopted a policy regarding the pre-approval of audit and non-audit services to be provided by our independent registered public accounting firm. At least annually, KPMG LLP provides a description of all audit and permissible non-audit services expected to be performed during the year and specific fee estimates for each such service, which must be pre-approved by the Audit Committee. KPMG LLP periodically reports to the Audit Committee regarding the extent of services provided in accordance with this pre-approval and the fees for the services performed to date. The Audit Committee has also delegated to the Chair of the Audit Committee the authority to pre-approve audit and permissible non-audit services and associated fees that were not pre-approved by the Audit Committee, up to a maximum amount of fees per audit or permissible non-audit service. The Chair is required to report any decisions to pre-approve such audit or non-audit services and fees to the full Audit Committee at its next regular meeting. All services performed by KPMG LLP during fiscal 2026 and 2025 were pre-approved by the Audit Committee in accordance with its pre-approval policy and as required by applicable SEC rules.

Vote Required for Approval

The affirmative vote of holders of a majority of the shares of our common stock represented in person or by proxy at the Annual Meeting and entitled to vote on this Proposal 3 is required to ratify the appointment of KPMG LLP as our independent registered public accounting firm. You may vote FOR, AGAINST or ABSTAIN on this proposal. Proxies received by our Board of Directors will be voted FOR this Proposal 3 unless specified otherwise.

Report of the Audit Committee

The following is the report of the Audit Committee with respect to our audited financial statements for the fiscal year ended July 3, 2026. This report shall not be deemed soliciting material or to be filed with the SEC or subject to Regulation 14A or 14C under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or to the liabilities of Section 18 of the Exchange Act, nor shall any information in this report be incorporated by reference into any past or future filing under the Securities Act of 1933, as amended (the “Securities Act”), or the Exchange Act, except to the extent we specifically request that it be treated as soliciting material or specifically incorporate it by reference into a filing under the Securities Act or the Exchange Act.

Dear Fellow Stockholders,

The Audit Committee represents our Board of Directors in discharging its responsibilities relating to the accounting, reporting and financial practices of Western Digital and its subsidiaries. The Audit Committee has general responsibility for oversight and review of the accounting and financial reporting practices, internal controls and accounting and audit activities of Western Digital and its subsidiaries. The Audit Committee is also responsible for overseeing our Enterprise Risk Management process on behalf of our Board. Accordingly, the Audit Committee oversees certain risk topics and allocates oversight responsibility for other risk topics among our Board and its other committees. The Audit Committee acts pursuant to a written charter. Our Board has adopted an Audit Committee Charter with the most recent amendment approved on February 14, 2022. A copy of the amended charter is available on our website under “Leadership & Governance” at investor.wdc.com. Our Board has determined that each of Mses. Alexy and Oulman and Mr. Kiddoo qualifies as an “audit committee financial expert” as defined by the SEC and that each of the members of the Audit Committee qualifies as an “independent” director under applicable rules of the Nasdaq Stock Market and the SEC.

Management is responsible for the preparation, presentation and integrity of Western Digital’s financial statements, the financial reporting process, accounting principles, as well as the internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. KPMG LLP, Western Digital’s independent registered public accounting firm, is responsible for performing an independent audit of Western Digital’s consolidated financial statements and internal control over financial reporting in accordance with auditing standards of the Public Company Accounting Oversight Board (United States), issuing reports thereon.

The Audit Committee is solely and directly responsible for the appointment, compensation, retention and oversight of Western Digital’s independent registered public accounting firm. The Audit Committee regularly solicits feedback from both management and the auditor in carrying out this responsibility. In conjunction with the rotation of the independent registered public accounting firm’s lead engagement partner, which occurs at least every five years, the Audit Committee is involved in the selection of KPMG LLP’s lead engagement partner. The next mandatory rotation for KPMG LLP’s lead engagement partner is scheduled to occur in fiscal 2030. The members of the Audit Committee are not professionally engaged in the practice of accounting or auditing and thus, its oversight does not provide an independent basis to determine that management has applied U.S. generally accepted accounting principles appropriately or maintained appropriate internal controls and disclosure controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations.

During fiscal 2026, the Audit Committee met a total of 8 times. During fiscal 2026, the Audit Committee also met and held discussions with management and KPMG LLP. The meetings were conducted to encourage communication among the members of the Audit Committee, management and the independent registered public accounting firm. The Audit Committee discussed with KPMG LLP the overall scope and plan for its audit. The Audit Committee met regularly with KPMG LLP, with and without management present, to discuss the results of its audit and quarterly reviews, its evaluation of Western Digital’s internal control over financial reporting and the overall quality of Western Digital’s accounting practices. As part of these discussions, the Audit Committee reviewed and discussed the audited consolidated financial statements of Western Digital for the fiscal year ended July 3, 2026 with management and KPMG LLP. The Audit Committee also discussed with KPMG LLP the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board and the SEC. Our Board, including the Audit Committee, received an opinion of KPMG LLP as to the conformity of such audited consolidated financial statements with GAAP and the effectiveness of internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act.

The Audit Committee has also received the written disclosures and the letter from KPMG LLP as required by the applicable requirements of the Public Company Accounting Oversight Board regarding KPMG LLP’s communications with the Audit Committee concerning independence and has discussed with KPMG LLP its independence. The Audit Committee reviewed and evaluated KPMG LLP’s lead engagement partner and also reviewed, among other things, the amount of fees paid to KPMG LLP for audit and non-audit services. Based upon such reviews and discussions, the Audit Committee recommended to our Board that the audited financial statements be included in Western Digital’s Annual Report on Form 10-K for the fiscal year ended July 3, 2026, as filed with the SEC. The Audit Committee also appointed KPMG LLP to serve as Western Digital’s independent registered public accounting firm for the fiscal year ending July 2, 2027. The members of the Audit Committee believe that the continued retention of KPMG LLP to serve as the independent registered public accounting firm is in the best interests of Western Digital and its stockholders.

During the Annual Meeting, we will answer as many stockholder-submitted questions as time permits, and any questions that we are unable to address during the Annual Meeting will be published and answered on our website following the meeting with the exception of any questions that are irrelevant to the purpose of the Annual Meeting or our business or that contain inappropriate or derogatory references which are not in good taste.

Voting Your Proxy

At the Annual Meeting

If your shares are registered directly in your name with our transfer agent, Equiniti Trust Company, LLC, you are considered the “stockholder of record” and you have the right to vote your shares electronically at the Annual Meeting. If you hold your shares through a broker, bank, trustee or other nominee (that is, in “street name”) rather than directly in your own name, you are a “beneficial stockholder” and you may also vote your shares electronically at the Annual Meeting. If you choose to do so, you can vote by following the instructions provided when you log in to the online virtual annual meeting platform. Even if you plan to attend the Annual Meeting, we recommend that you submit your proxy or voting instructions in advance of the meeting as described below so that your vote will be counted if you later decide not to attend the Annual Meeting.

Without Attending the Annual Meeting

You may also direct how your shares are voted without attending the Annual Meeting. If you are a stockholder of record, you may submit a proxy to authorize how your shares are voted at the Annual Meeting. You can submit a proxy over the Internet by following the instructions provided in the “Notice of Internet Availability of Proxy Materials” (which we also refer to as the “Notice”), or, if you received a printed copy of the proxy materials, you can also submit a proxy by mail or telephone. If you are a beneficial stockholder, you may submit your voting instructions over the Internet by following the instructions provided in the Notice, or, if you received a printed copy of the proxy materials, you can also submit voting instructions by telephone or mail by following the instructions provided by your bank, broker, trustee or other nominee.

Submitting your proxy or voting instructions via the Internet, by telephone or by mail will not affect your right to vote electronically should you decide to attend the Annual Meeting.

If you submit a signed proxy or voting instruction form but do not indicate your specific voting instructions on one or more of the proposals listed in the Notice of Annual Meeting of Stockholders, your shares will be voted as recommended by our Board of Directors on those proposals and as the proxyholders may determine in their discretion with respect to any other matters properly presented for a vote at the Annual Meeting.

Voting Deadline

If you are a stockholder of record, please submit your proxy by telephone, the Internet or mail by 11:59 p.m. Eastern time on November 19, 2026 in order for your shares to be voted at the Annual Meeting. If you are a beneficial stockholder, please follow the voting instructions provided by the bank, broker, trustee or nominee who holds your shares.

Revoking Your Proxy

You have the power to revoke your proxy or voting instructions before your shares are voted at the Annual Meeting. If you are a stockholder of record, you may revoke your proxy by submitting a written notice of revocation to our Secretary (see page 82 for contact information), or, to change how your shares will be voted at the Annual Meeting, by mailing a duly executed written proxy bearing a date that is later than the date of your original proxy or by submitting a later dated proxy via the Internet or by telephone.

A previously submitted proxy will not be voted if the stockholder of record who executed it attends the Annual Meeting and votes the shares represented by the proxy electronically at the Annual Meeting. For shares you hold beneficially in street name, you may change your vote by submitting new voting instructions to your bank, broker, trustee or nominee or by attending the Annual Meeting and voting electronically. Please note that attending the Annual Meeting will not by itself constitute revocation of a proxy. Any change to your proxy or voting instructions should be submitted by telephone, the Internet or mail by 11:59 p.m. Eastern time on November 19, 2026.

Quorum

The holders of a majority of our shares of common stock outstanding on the record date and entitled to vote at the Annual Meeting, present or represented by proxy, will constitute a quorum for the transaction of business at the Annual Meeting and any postponements or adjournments thereof. If you submit a proxy or voting instructions, your shares will be counted for purposes of determining the presence or absence of a quorum, even if you abstain from voting your shares. If a broker indicates on a proxy that it lacks discretionary authority to vote your shares on a particular matter, commonly referred to as “broker non-votes,” those shares will also be counted for purposes of determining the presence of a quorum at the Annual Meeting. If a quorum is not present, the Annual Meeting will be adjourned until a quorum is obtained.

Abstentions and Broker Non-Votes

Abstentions

Shares voting “ABSTAIN” on any of the proposals at the Annual Meeting are treated differently depending on the specific proposal.

lProposal 1: Abstentions will be entirely excluded from the vote and will not be counted in determining the outcome of a director nominee’s election.

lProposals 2 and 3: We treat abstentions as shares present or represented and entitled to vote on these proposals, so abstaining has the same effect as a vote “against” these proposals.

Broker Non-Votes

If you are a beneficial stockholder that holds your shares through a brokerage account and you do not submit voting instructions to your broker, your broker may generally vote your shares in its discretion on routine matters. However, a broker cannot vote shares held for a beneficial stockholder on non-routine matters, unless the broker receives voting instructions from the beneficial stockholder. Proposal 3 (ratification of KPMG LLP as our independent registered public accounting firm) is considered routine and may be voted upon by your broker if you do not submit voting instructions. However, all other proposals to be voted on at the Annual Meeting are considered non-routine matters. Consequently, if you hold your shares through a brokerage account and do not submit voting instructions to your broker, your broker may exercise its discretion to vote your shares on Proposal 3, but will not be permitted to vote your shares on any of the other proposals at the Annual Meeting. If your broker exercises this discretion, your shares will be counted as present for determining the presence of a quorum at the Annual Meeting and will be voted on Proposal 3 in the manner directed by your broker, but your shares will constitute broker non-votes on each of the other proposals at the Annual Meeting and will have no effect in determining the outcome of each such proposal.

Voting Results

We intend to announce preliminary voting results at the Annual Meeting and disclose final results in a Current Report on Form 8-K to be filed with the SEC no later than four business days following the date of the Annual Meeting.

Costs of Proxy Solicitation

The accompanying proxy is being solicited on behalf of our Board of Directors. The cost of preparing, assembling and mailing the Notice of Annual Meeting of Stockholders, the Notice of Internet Availability of Proxy Materials, this Proxy Statement and form of proxy and our 2026 Annual Report, the cost of making such materials available on the Internet and the cost of soliciting proxies will be paid by us. In addition to use of the mails, we may solicit proxies in person or by telephone, facsimile or other means of communication by certain of our directors, officers and regular employees who will not receive any additional compensation for such solicitation. We also engaged Okapi Partners LLC, 1212 Avenue of the Americas, 17th Floor, New York, NY 10036, to assist us in connection with the solicitation of proxies for the Annual Meeting for a fee that we do not expect to exceed $15,000 plus a reasonable amount to cover expenses. We have agreed to indemnify Okapi Partners against certain liabilities arising out of or in connection with this engagement. We will also reimburse brokers or other persons holding our common stock in their names or the names of their nominees for the expenses of forwarding soliciting material to their principals.

If we change the date of the 2027 Annual Meeting by more than 30 days from the date of this year’s Annual Meeting, your written proposal must be received by our Secretary at our principal executive offices a reasonable time before we begin to print and mail our proxy materials for our 2027 Annual Meeting.

Nomination of Director Candidates and Proposals Not Intended for Inclusion in Proxy Materials

If you intend to nominate an individual for election to our Board of Directors at our 2027 Annual Meeting or wish to present a proposal at the 2027 Annual Meeting but do not intend for such proposal to be included in the proxy statement for such meeting, our Bylaws require that, among other things, stockholders give written notice of the nomination or proposal to our Secretary at our principal executive offices no earlier than the close of business on July 23, 2027 (the 120th day prior to the first anniversary of the Annual Meeting) and no later than the close of business on August 22, 2027 (the 90th day prior to the first anniversary of the Annual Meeting).

Notwithstanding the foregoing, in the event that we change the date of the 2027 Annual Meeting to a date that is more than 30 days before or more than 70 days after the anniversary of the Annual Meeting, written notice by a stockholder must be given no earlier than the close of business 120 days prior to the date of the 2027 Annual Meeting and no later than the close of business on the later of 90 days prior to the date of the 2027 Annual Meeting or the 10th day following the day on which public announcement of the date of the 2027 Annual Meeting is made.

The written notice must also satisfy the information and other specified requirements set forth in Section 2.11 of our Bylaws. In accordance with our Bylaws, the foregoing deadline and notice requirements set forth in Section 2.11 of our Bylaws are also intended to apply to and satisfy the deadline and notice requirements set forth in paragraph (b) of Rule 14a-19 under the Exchange Act with respect to notice by a stockholder who intends to solicit proxies in support of director nominees other than the company’s nominees at the 2027 Annual Meeting.

Nomination of Director Candidates for Inclusion in Proxy Materials (Proxy Access)

If you intend to nominate a director candidate pursuant to the proxy access process set forth in Section 2.14 of our Bylaws, you, or a group of not more than 20 stockholders, must, among other requirements, have owned 3% or more of our outstanding common stock continuously for at least three years and give written notice of the nomination to our Secretary at our principal executive offices no earlier than the close of business on May 8, 2027 (the 150th day prior to the first anniversary of the date that proxy materials for the Annual Meeting were first released to stockholders) and no later than the close of business on June 7, 2027 (the 120th day prior to the first anniversary of the date that proxy materials for the Annual Meeting were first released to stockholders).

Notwithstanding the foregoing, in the event that we change the date of the 2027 Annual Meeting to a date that is more than 30 days before or more than 70 days after the anniversary of the Annual Meeting, written notice by a stockholder must be given no earlier than the close of business 150 days prior to the date of the 2027 Annual Meeting and no later than the close of business on the later of 120 days prior to the date of the 2027 Annual Meeting or the 10th day following the day on which public announcement of the date of the 2027 Annual Meeting is made.

Use of the proxy access process is subject to all eligibility, procedural and disclosure requirements set forth in Section 2.14 of our Bylaws.

Eliminating Duplicative Proxy Materials

We have adopted a procedure called “householding,” which the SEC has approved. Under this procedure, stockholders of record who have the same address and last name and did not receive a Notice or otherwise receive their proxy materials electronically will receive only one copy of our proxy materials unless we receive contrary instructions from one or more of such stockholders. Upon oral or written request, we will deliver promptly a separate copy of the proxy materials to a stockholder at a shared address to which a single copy of proxy materials was delivered. If you are a stockholder of record at a shared address to which we delivered a single copy of the proxy materials and you desire to receive a separate copy of the proxy materials for the Annual Meeting or for our future meetings, or if you are a stockholder at a shared address to which we delivered multiple copies of the proxy materials and you desire to receive one copy in the future, please submit your request to the Householding Department of Broadridge Financial Solutions, Inc. at 51 Mercedes Way, Edgewood, New York 11717, or at 1-866-540-7095. If you are a beneficial stockholder, please contact your bank, broker, trustee or other nominee directly if you have questions, require additional copies of the proxy materials, wish to receive multiple reports by revoking your consent to householding or wish to request single copies of the proxy materials in the future.

Appendix A—Non-GAAP Financial Measures

We have disclosed in this Proxy Statement financial measures that are not in accordance with U.S. generally accepted accounting principles (“GAAP”). These non-GAAP measures are not alternatives for measures prepared in accordance with GAAP and may be different from similarly titled non-GAAP measures used by other companies. We believe the presentation of these non-GAAP measures, when shown in conjunction with the corresponding GAAP measures, provides useful information to investors for measuring our performance and comparing it against prior periods. These non-GAAP measures are used by management for assessing our financial performance and as a measurement of our performance for incentive compensation purposes. These measures should be considered in addition to financial measures prepared in accordance with GAAP, but should not be considered a substitute for, or superior to, GAAP results.

The Compensation and Talent Committee used non-GAAP operating income as a pre-established performance goal under the STI plan for fiscal 2026 and non-GAAP diluted net income per common share (which we also refer to as non-GAAP EPS) and adjusted free cash flow as pre-established performance goals under the fiscal 2026-2028 PSU awards and fiscal 2026-2027 CEO PSU award. In accordance with the pre-established terms of the STI and PSU awards, these non-GAAP performance measures excluded certain material or unusual items that we believe are not indicative of the underlying performance of our business as detailed below.

Reconciliations of Non-GAAP Financial Measures

The following non-GAAP measures (namely, non-GAAP gross profit, non-GAAP operating income, non-GAAP EPS and adjusted free cash flow) exclude certain expenses, gains and losses that we believe are not indicative of our core operating results or because they are consistent with the financial models and estimates published by many analysts who follow our company and our peers. As further detailed below, the expenses, gains and losses excluded from the following non-GAAP measures consist of stock-based compensation expense; charges related to a litigation matter; business realignment charges (credits); and other adjustments.

The following tables present reconciliations of our non-GAAP gross profit, non-GAAP operating income, non-GAAP EPS and adjusted free cash flow to the most directly comparable GAAP measures:

Appendix A

Explanations of Adjustments to Non-GAAP Measures

As detailed above, we exclude the following items from our non-GAAP financial measures:

Stock-based compensation expense. Because of the variety of equity awards used by companies, the varying methodologies for determining stock-based compensation expense, the subjective assumptions involved in those determinations, and the volatility in valuations that can be driven by market conditions outside the company’s control, the company believes excluding stock-based compensation expense enhances the ability of management and investors to understand and assess the underlying performance of its business over time and compare it against the company’s peers, a majority of whom also exclude stock-based compensation expense from their non-GAAP results.

Litigation matter. In previous periods, the company had recognized expenses related to a judgment in a patent litigation matter, which consisted of an award of damages, interest, estimated plaintiff legal costs and other charges. A portion of these expenses were reversed upon a subsequent settlement with the plaintiff. The company believes these charges and subsequent reversals do not reflect the company’s operating results and that they are not indicative of the underlying performance of its business.

Business realignment charges (credits). From time to time, in order to realign the company’s operations with anticipated business needs or to achieve cost synergies from the integration of acquisitions, the company may incur charges in connection with actions to terminate employees, impair assets or otherwise restructure its operations and may recognize credits related to charges previously incurred. These charges (credits) are inconsistent in amount and frequency, and the company believes they are not indicative of the underlying performance of its business.

Gain on retained interest in Sandisk. The company retained an ownership interest in Sandisk at the time of the Separation and recognized gains on the mark-to-market adjustment of such interest. The company believes these adjustments do not reflect the company’s operating results and are not indicative of the underlying performance of its business.

Costs in connection with debt and equity transactions. In connection with the company’s actions to monetize its retained interest in Sandisk and reduce its debt, it completed a number of transactions, including a debt-for-equity exchange, equity-for-equity exchanges, and the private settlement of a portion of our convertible note obligations. In connection with these transactions, the company recognized costs primarily related to a discount given to the counterparty of the transaction. The company believes these costs do not reflect the company’s operating results and are not indicative of the underlying performance of its business.

Income tax adjustments. Income tax adjustments represent the difference between income taxes based on a forecasted annual GAAP tax rate and a forecasted annual non-GAAP tax rate, which have been adjusted to account for the tax effects of items excluded from non-GAAP pre-tax income as well as the tax effects of non-recurring and period-specific tax items. These adjustments are excluded because the company believes that they are not indicative of the underlying performance of its ongoing business.

Other adjustments. From time to time, the company records costs, charges, and benefits that the company believes are not a part of the ongoing operation of its business. The resulting expense or benefit is inconsistent in amount and frequency.
