LETTER FROM OUR CHAIR AND

LEAD INDEPENDENT DIRECTOR

Dear Fellow Stockholders:

We are pleased to invite you to attend the 2025 Annual Meeting of Stockholders, our first as a newly independent, publicly traded company. This meeting represents a defining moment in Sandisk's history and a significant milestone in our reemergence as a standalone global leader in flash-based storage solutions.

In February 2025, Sandisk formally separated from Western Digital, completing a successful transition and reintroduction to the market. In this new era for Sandisk, we are laser-focused on creating value for customers and stockholders by leveraging our greatest strengths in innovation, scale, agility, and operational discipline. While our post-separation period in fiscal 2025 was brief, we are proud of the progress made in performance, leadership, and governance, which has laid a strong foundation for Sandisk's long-term success.

Our Board Represents Institutional Insight and Strategic Renewal

We are guided by a highly experienced and strategically balanced Board of Directors. Our Board consists of a combination of former Western Digital board members who provide deep insight on Sandisk's business, technology, talent, and long-term strategic goals, and new members who bring fresh perspectives to the boardroom. We are confident that our Board is well-positioned to steward Sandisk as a standalone company. We believe everything starts with innovation, and our business sits at the center of it. With a dedicated focus on advancing Sandisk's core business, we see a tremendous opportunity to deliver meaningful value to both our customers and stockholders.

We will nominate seven directors at our inaugural annual meeting, all of whom have served since our separation from Western Digital. As part of the separation, we appointed to our Board two current Western Digital directors – Matthew Massengill and Kimberly Alexy – to provide leadership continuity through the transition. As we believe Sandisk is now in a strong position to drive long-term success and value creation for its stockholders, Mr. Massengill and Ms. Alexy will not be nominated for reelection at the annual meeting. Our director nominees include independent directors with expertise across critical domains, including semiconductors, enterprise systems, capital markets, and human capital. The skills of our director nominees are closely aligned with our business priorities and opportunities ahead and are essential skills for driving long-term value creation. We are excited for our Board to effectively guide and oversee Sandisk through its evolution as a standalone company.

Our Clear Strategy for Long-term Value Creation

Sandisk's strategy is focused and purpose-built for the opportunities ahead. As a standalone company, we are reaffirming our leadership in the NAND and SSD markets while sharpening our operational and capital allocation decisions to deliver sustainable and profitable growth objectives. We are executing a long-term vision that reflects our core strengths. In doing so, we are positioning Sandisk to capture a significant market opportunity. Our growth is being driven by the exponential expansion of data, the rise of artificial intelligence in cloud and edge applications, and upcoming refresh cycles in personal computers and mobile devices. Our capital investment remains strong in data centers where we are seeing emerging AI-driven workloads expand the addressable market for enterprise SSDs, which we believe is unlocking further potential for Sandisk's flash solutions.

In parallel, we have made structural changes to how we operate by, for example, tightening our focus on capital discipline and driving higher returns on invested capital. These are not just goals, they are embedded principles of how Sandisk creates long-term stockholder value.

Our successful first half-year as a standalone company exceeded expectations. We remain optimistic as we lead with innovation to meet demand, which we forecast to strengthen throughout the year. We continue to focus on maximizing return on invested capital through supply management, costs, and pricing strategies.

A Commitment to Good Governance and Our Stockholders

Governance has been a priority through the separation, and we have taken significant steps toward establishing the rigor and practices characteristic of a mature, best-in-class public company, and we will continue to evaluate our governance practices in this pursuit. Our Board prioritizes strong and independent oversight, and we maintain policies aligned with investor expectations, including a commitment to a robust stockholder engagement program. Transparency, accountability, and long-term alignment with stockholders are central to our governance philosophy.

On behalf of the full Board and executive team, thank you for the trust you have placed in Sandisk as we reintroduce ourselves as a standalone company. Our first fiscal year has been foundational, and the support and feedback of our investors has been essential. We look forward to continuing our journey together.

Sincerely,

---

Executive Compensation Highlights

Executive Compensation Objectives and Approach

The Compensation and Talent Committee seeks to closely align pay with performance, rewarding executives for delivering results for Sandisk and its stockholders. Our compensation program is designed to offer market-competitive incentives to drive talent retention and incentivize excellence in performance and stockholder value creation. We are committed to setting executive compensation around value-driving metrics, rigorous performance hurdles, and meaningful at-risk pay to ensure accountability and alignment with stockholder interests.

We are proud of the steps the committee took immediately following our separation from Western Digital to align executive compensation with Sandisk's strategic goals and stockholders' interests. The second half of fiscal 2025 ("2H Fiscal 2025") compensation design reflects the committee's goal of incentivizing leadership to execute a successful transition and position our company for long-term success. The committee looks forward to discussing the evolution of our compensation program for our first full fiscal year. For more information regarding our executive compensation practices, and our approach to drive accountability, transparency, and long-term value creation, please see page [35](#i114f29450cd44bb4a6e3ecaf5327c40e_800).

| **(→)** | We are asking our stockholders to elect seven directors to our Board of Directors at the 2025 annual meeting of stockholders. Defining attributes of our Board include:<br>**•** All directors elected annually by a simple majority of votes cast<br>**•** Six of seven director nominees are independent<br>**•** Independent Board leadership, consisting of a Lead Independent Director with clearly defined roles and responsibilities<br>**•** Skills and experience of directors aligned to business strategy and key areas of risk oversight<br>**•** Women currently serve in key Board leadership positions such as our Chairs of the Audit Committee and Compensation and Talent Committee |
| **(→)** | Our Board of Directors recommends a vote FOR each of the seven director nominees named in this Proxy Statement |

---

Our Board of Directors is presenting seven nominees for election as directors at our 2025 annual meeting of stockholders ("Annual Meeting"). Each of the nominees is currently a member of our Board and was elected to our Board by our stockholder and former parent company, Western Digital Corporation ("WDC"), in connection with our separation from WDC that became effective February 21, 2025 (the "Separation"). Each director elected at the Annual Meeting will serve until our 2026 annual meeting of stockholders (the "2026 Annual Meeting") and until a successor is duly elected and qualified or until the director's earlier resignation.

All of our director nominees joined our Board in connection with the Separation. Mr. Caulfield, Mr. Goeckeler, and Ms. Suzuki were identified and selected by the WDC board of directors, and Mr. Cassidy, Mr. Kumar, Mr. Sayiner, and Ms. Shook were identified and selected by the WDC board of directors with the assistance of a search firm.

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, or our Board may choose to reduce its size.

As part of the Separation, Mr. Massengill and Ms. Alexy joined our Board to provide leadership continuity through the transition. As we believe the Company is now in a strong position to drive long-term success and value creation for its stockholders, Mr. Massengill and Ms. Alexy will not be nominated for reelection at the Annual Meeting and will cease their service on the Board of Directors when their terms expire immediately before the Annual Meeting.

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 or other designated Board 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 Board's non-employee director nominees (Messrs. Cassidy, Caulfield, Kumar, or Sayiner, or Mses. Shook, or Suzuki) and none of our other current non-employee directors who are not continuing on the Board following the Annual Meeting (Mr. Massengill and Ms. Alexy) 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. Goeckeler 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.

Director Meeting Attendance

During fiscal 2025, representing approximately four months as a standalone company, our full Board of Directors met three times. Each of the directors who served during fiscal 2025 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 2025.

Our Board strongly encourages each director to attend our annual meeting of stockholders. As a result of the Separation, we did not hold an annual meeting of stockholders in fiscal 2025.

**STRONG DIRECTOR ENGAGEMENT**

Average director attendance at fiscal 2025 Board and committee meetings:

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 mix of backgrounds and expertise, which are most needed and beneficial to our Board and our company.

The Governance Committee commits to annually evaluate the size and composition of our Board and assess whether the composition appropriately aligns with our evolving business and strategic needs. Through this process, the Governance Committee develops a list of qualifications, skills and attributes to be considered when seeking and evaluating director candidates. Specific director criteria evolve over time to reflect our strategic and business needs and the changing composition of our Board.

Director Candidate Pool Provision

Our Corporate Governance Guidelines require the Governance Committee to include, and instruct any search firm it engages to include, women and members of underrepresented communities in the pool from which the committee selects director nominees.

Director Nomination Process

Step 1: Assess

Our Board of Directors, led by the Governance Committee, evaluates the size and composition of our Board at least annually, and to consider 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 will develop 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.

Step 2: 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 an outside search firm to identify suitable potential director candidates. The committee will include, and instruct any search firm it engages to include, women and members of underrepresented communities in the pool of director candidates.

Step 3: Evaluate

The Governance Committee commits to establishing a process for evaluating director candidates that it will follow regardless of who recommends a candidate for consideration. Through this process, the committee will consider a candidate's skills, experience, outside commitments, including service on public company boards, and other available information regarding each candidate. For incumbent director candidates, this process is expected to include consideration of the results of the annual Board and committee evaluations during our first full fiscal year as an independent company. See the section entitled "Board Processes and Policies—Board and Committee Evaluations" below. Following the evaluation, the committee recommends nominees to our Board.

Step 4: 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.

Stockholder Recommendations of Director Candidates

The Governance Committee may receive recommendations for director candidates from our stockholders. A stockholder may recommend a director candidate to the Governance Committee by delivering a written notice to our Secretary at our principal executive offices and including the following in the notice: the name and address of the stockholder as they appear on our books or other proof of share ownership; the class and number of shares of our common stock beneficially owned by the stockholder as of the date the stockholder gives written notice; a description of all arrangements or understandings between the stockholder and the director candidate and any other person(s) pursuant to which the recommendation or nomination is to be made by the stockholder; the name, age, business address and residence address of the director candidate and a description of the director candidate's business experience for at least the previous five years; the principal occupation or employment of the director candidate; the class and number of shares of our common stock beneficially owned by the director candidate; the consent of the director candidate to serve as a member of our Board of Directors if appointed or elected; and any other information required to be disclosed with respect to a director nominee in solicitations for proxies for the election of directors pursuant to applicable rules of the SEC.

The committee may require such additional information as it deems reasonably required to determine the eligibility of the director candidate to serve as a member of our Board of Directors. Stockholders recommending candidates for consideration by our Board in connection with the next annual meeting of stockholders should submit their written recommendation no later than June 1 of the year of that meeting.

The committee will evaluate director candidates recommended by stockholders for election to our Board in the same manner and using the same criteria as it uses for any other director candidate. If the committee determines that a stockholder-recommended candidate is suitable for membership on our Board, it will include the candidate in the pool of candidates to be considered for nomination upon the occurrence of the next vacancy on our Board or in connection with the next annual meeting of stockholders.

Board Refreshment

Our Board of Directors believes that periodic Board refreshment can provide new experience and fresh perspectives to our Board and is most effective if it is sufficiently balanced to maintain continuity among Board members that will allow for the sharing of historical perspectives and experience relevant to our company. Our Board seeks to achieve this balance through its director succession planning process described below. Our Board will also utilize the annual Board and individual director assessment process discussed below under "Board Processes and Policies—Board and Committee Evaluations" to help inform its assessment of our Board's composition and Board refreshment needs after our first full fiscal year as an independent company. Our Board commits to regularly evaluate its composition, in order to both add and maintain skills critical to overseeing our business as our strategy and oversight priorities evolve.

Succession Planning

Our Board of Directors is focused on ensuring that it has members with a variety of skills, expertise, experience, age, and backgrounds because a broad range of perspectives is critical to effective corporate governance and overseeing the execution of our strategy. The Governance Committee's long-range succession planning role is intended to help identify and recruit new directors but also ensures a smooth transition when succession needs arise. The committee will also oversee the orderly succession of our Chairs of the Board committees.

Director Orientation and Education

All incoming directors participate in a director orientation program. The orientation includes meetings with, and presentations by, the executive team and senior management on key topics, such as business and operations, governance policies and practices, finance, accounting and audit matters, and our products and technology. When directors accept new or additional responsibilities on our Board or on committees, they will be provided additional orientation and educational opportunities on relevant topics, as needed.

Because our Board believes that ongoing director education is vital to the ability of directors to fulfill their responsibilities, we intend to invite external subject matter experts to present to our Board at least annually on emerging and evolving issues relevant to our business strategy. The Governance Committee will select the topics on which to focus. We also encourage directors to participate in external 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-term 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. 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 members of management, including those involved in ERM, and has access to external 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 2025 Annual Report on Form 10-K, which is also reviewed with the Audit Committee.

The independence of our Board and our Board leadership enhances our Board's ability to exercise its risk oversight. Through the authority of our Lead Independent Director to establish Board agendas, and call and preside at Board meetings and executive sessions of our independent directors as described under "Board Structure—Board Leadership Structure" below, our current Board leadership structure offers mechanisms to facilitate our Board's exercise of its oversight responsibilities. This includes requiring management reports on specific risk exposures and requesting additional information or directing alternative actions with respect to management's recommendation on any risk matters as our Board may determine to be necessary or advisable.

Compensation Risk Assessment

Consistent with SEC disclosure requirements, the Compensation and Talent Committee, working with its independent compensation consultant, reviewed our fiscal 2025 compensation policies and practices to determine whether they encourage excessive risk taking. The committee 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 disposition of our securities by all 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 2025 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.

Sustainability and Corporate Responsibility

We keep people and businesses moving forward with inspired innovations to actualize their potential. The mobility, creativity, and potential that our products unlock for customers inspires us to innovate and deliver more for our customers—today and everyday. Reflected in our values—Innovation, Sustainability, Collaboration and Community and Responsible Leadership, we are committed to developing products and operating with people and the planet in mind. We know that every choice makes an impact on the world we share, which is why we prioritize environmental stewardship and keeping the people who power our operations and supply chain safe.

Our commitment to environmental and social responsibility drives us to continuously evaluate, improve, and realize more efficient and resilient business operations. Our efficiency delivers value across the business, such as resource efficiency, product quality, reduced risks of misconduct and legal liability, enhanced reliability of our supply chain, and an engaged, healthy and productive workforce. We know that being an industry leader is not just about having talented employees or innovative products, it's also about doing business the right way, every day. That is why our commitment to corporate responsibility is deeply embedded throughout our business.

We look forward to publishing our inaugural 2025 Sustainability Report in late calendar year 2025, which will be located on our website at **www.sandisk.com/company/corporate-responsibility**.

Oversight by Our Board of Directors

Sound corporate responsibility in all aspects of our business is a focus of our Board of Directors. 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 will receive 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.

In addition, the Compensation and Talent Committee will periodically review our people policies and programs, including those focusing on talent attraction, engagement and retention, and other topics as may be designated by our Board from time to time.

Our People

We believe data should inspire every person—to move, create, discover, share, and unlock their potential. For more information on our people, please refer to the human capital management section of our 2025 Annual Report on Form 10-K filed with the SEC on August 21, 2025.

Communication with Management

We commit to having the following practices to promote clear, timely and regular communication between directors and management.

**• Business Updates.** Between Board meetings, our Board receives updates from our CEO and management, including on key company developments.

**• Engagement with Management.** Our Board regularly interacts with our CEO and management during and between Board meetings through meetings and informal gatherings of our Board and management.

**• Meeting Agendas and Presentations.** Our Lead Independent Director and committee Chairs regularly communicate with management to discuss the development of meeting agendas and presentations.

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.

Succession Planning

The Compensation and Talent Committee oversees CEO and key management personnel succession planning. We plan for directors to engage with potential CEO and key management personnel successors at Board and committee meetings, as well as in less formal settings to allow directors to personally assess candidates. Furthermore, our Board will periodically review the overall composition of our key management personnel's qualifications, tenure and experience.

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 will be reviewed annually by the Governance Committee and our Board.

Stockholder Engagement

We commit to regular, ongoing stockholder engagement to discuss our business, programs, and practices and solicit feedback for our Board's consideration and responsiveness. Our Board values stockholder feedback as a critical input in its deliberations and decision-making process. Members of our Board and executive team seek to meet with stockholders to discuss our business and gain valuable insights on investors' perspectives on relevant topics, including, among others, strategy, governance, executive compensation, and sustainability.

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 giving consideration to, 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 do not separate the roles of CEO and Chair of the Board, with Mr. Goeckeler currently serving as both CEO and Chair of the Board. Our Board believes this is the appropriate leadership for our company post-Separation, because it allows for faster decision-making and efficiency, promotes unified leadership and clear accountability, and reinforces deep operational knowledge.

Our Corporate Governance Guidelines provide that our Board will appoint a Lead Independent Director if our Chair of the Board is not an independent director under the Nasdaq Stock Market listing standards or if our Board otherwise deems it appropriate. Since Mr. Goeckeler is our CEO and therefore not considered independent under the Nasdaq Stock Market listing standards, Mr. Massengill currently serves as our Lead Independent Director. Once Mr. Massengill's service ends, our Board intends to appoint a new Lead Independent Director. Our Lead Independent Director plays an important role in maintaining effective independent oversight of our company. During his tenure, Mr. Massengill's strong leadership skills, significant public company board experience, contributions to the Separation, and service as the Governance Committee Chair qualified him to serve as our Lead Independent Director.

The responsibilities of our Chair of the Board and our Lead Independent Director are summarized in the following table:

---

| |
|:---|
| &nbsp;&nbsp;&nbsp;**Chair of the Board** |
| &nbsp;&nbsp;&nbsp;&nbsp;**•** Leads our Board of Directors in overseeing the management and direction of our company<br>&nbsp;&nbsp;&nbsp;&nbsp;**•** Calls meetings of our Board and stockholders<br>&nbsp;&nbsp;&nbsp;&nbsp;**•** Chairs meetings of our Board and the annual meeting of stockholders<br>&nbsp;&nbsp;&nbsp;&nbsp;**•** Establishes Board meeting schedules and agendas<br>&nbsp;&nbsp;&nbsp;&nbsp;**•** Calls executive sessions of our independent directors<br>&nbsp;&nbsp;&nbsp;&nbsp;**•** Engages in discussions with members of our management and our Board, as appropriate<br>&nbsp;&nbsp;&nbsp;&nbsp;**•** Engages in discussions with our stockholders and other stakeholders on relevant matters, as appropriate<br>&nbsp;&nbsp;&nbsp;&nbsp;**•** Communicates with all directors on key issues and concerns outside of Board meetings |
| &nbsp;&nbsp;&nbsp;**Lead Independent Director** |
| &nbsp;&nbsp;&nbsp;&nbsp;**•** Acts as a liaison between our independent directors and management<br>&nbsp;&nbsp;&nbsp;&nbsp;**•** Assists our Chair of the Board in establishing the agenda for Board meetings<br>&nbsp;&nbsp;&nbsp;&nbsp;**•** Coordinates the agenda for and chairs the executive sessions of the independent directors<br>&nbsp;&nbsp;&nbsp;&nbsp;**•** Presides at the meetings of our Board of Directors in the absence of our Chair of the Board<br>&nbsp;&nbsp;&nbsp;&nbsp;**•** Be available for engagement with stockholders, as appropriate<br>&nbsp;&nbsp;&nbsp;&nbsp;**•** Performs such other duties as may be specified by our Board of Directors from time to time |

---

While our Chair of the Board and Lead Independent Director have authority to establish Board meeting agendas, propose actions for approval and represent the interests of our company and our Board in discussions with management and our stockholders, any specific actions taken in connection with these matters are exercised by our full Board or any Board committee to which authority has been delegated, and not by any individual director.

Executive Sessions

All members of our Board of Directors, other than our CEO, are independent. In connection with our efforts to support that our independent directors are not inappropriately influenced by management, the independent directors typically meet without management in executive sessions led by our Lead Independent Director in conjunction with each regularly scheduled meeting of our Board, and otherwise as deemed necessary by 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.

Committees

Our Board of Directors has standing Audit, Compensation and Talent, Governance and Executive Committees. Each of the standing committees operates pursuant to a written charter that is available on our website under "Governance" at **investor.sandisk.com**. Our Board has affirmatively determined that all members of the Audit, Compensation and Talent and Governance Committees are independent as defined under the listing standards of the Nasdaq Stock Market and applicable SEC rules.

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:

**•** The role and responsibilities of our Lead Independent Director

**•** Director nomination procedures and qualifications

**•** Director independence

**•** Policies related to board refreshment and limitations on other board service

**•** Director orientation and continuing education

**•** Annual performance evaluations of our Board and committees

**•** Succession planning and management development

Our Board of Directors has also adopted a Code of Business Ethics that applies to all of 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 "Governance" at **investor.sandisk.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 "Governance" at **investor.sandisk.com**, to the extent required by applicable rules and regulations of the SEC or the Nasdaq Stock Market.

Director Overboarding Policy

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.

---

| |
|:---|
| **Directors** |
| A director may not simultaneously serve on the boards of more than 5 public companies (including Sandisk) |
| **CEO** |
| Our CEO may not simultaneously serve on the boards of more than 2 public companies (including Sandisk) |

---

All incumbent 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 will review 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.

Board and Committee Evaluations

Commencing with the first full fiscal year following the Separation, our Board will engage in a comprehensive annual Board and Board committee evaluation process. Our Board believes that a thorough evaluation process that encourages director engagement will foster constructive feedback and enhance our Board's overall effectiveness. Accordingly, the Governance Committee will oversee an annual performance evaluation process that includes the following:

---

| |

| Each director will complete a written questionnaire soliciting feedback on various topics, including:<br>**•** Board meetings and materials<br>**•** Board composition<br>**•** Board committee performance<br>**•** Relationships with management<br>**•** Communications among and between our Board and management<br>**•** Our Board's strategic oversight role<br>**•** Management and Board succession planning<br>**•** Overall Board effectiveness |
| &nbsp;&nbsp; ![02_PRO014126_icon_arrowdown.jpg](sndk-20251006_g100.jpg) |
| &nbsp;&nbsp;**Discussions with Each Director** |
| An outside firm will compile and analyze the results of each written evaluation and will summarize the results on an aggregated and anonymous basis, which our Governance Committee Chair will discuss with each director to solicit further feedback. |
| &nbsp;&nbsp; ![02_PRO014126_icon_arrowdown.jpg](sndk-20251006_g100.jpg) |
| &nbsp;&nbsp;**Results Discussed with the Full Board and Each Committee** |

| &nbsp;&nbsp;**Individual Director Assessments** |
| As part of the annual performance evaluation process, each director will also complete a written self-evaluation covering various topics, including:<br>**•** Meeting attendance, preparation and participation<br>**•** Understanding of our business and strategy<br>**•** Relationships with management and other directors<br>Our Lead Independent Director will discuss individual self-evaluation responses with each director. |
| &nbsp;&nbsp; ![02_PRO014126_icon_arrowdown.jpg](sndk-20251006_g100.jpg) |
| &nbsp;&nbsp;**Evaluation Results** |
| The information collected during our Board evaluation process will be utilized by our Board to make decisions regarding Board structure, Board committees and their responsibilities, agendas and meeting schedules, changes in the performance or function of our Board and continued service of individual directors. The Governance Committee will oversee and monitor the actions taken as a result of the Board evaluations at each of its regular meetings. |

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 Lead Independent Director 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 [70](#i114f29450cd44bb4a6e3ecaf5327c40e_608) 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 Chair of the Board, Lead Independent Director 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

Certain Transactions with Related Persons

Material Agreements with WDC

In connection with the Separation, our company and WDC entered into the agreements described below.

The following are summaries of certain provisions of these agreements, which are qualified in their entirety by reference to all of the provisions of such agreements. Because these descriptions are only summaries of the applicable agreements, they do not necessarily contain all of the information that you may find useful. We therefore encourage you to review the agreements in their entirety. Copies of the agreements (or forms of the agreements) are included as exhibits to our Annual Report on Form 10-K for our fiscal year ended June 27, 2025 and are available electronically on the website of the SEC at **www.sec.gov**.

The Separation and Distribution Agreement

The separation and distribution agreement sets forth our agreement with WDC regarding the principal transactions necessary to separate Sandisk from WDC, including the transfer of assets, assumption of liabilities, releases and indemnification obligations, insurance responsibilities, non-compete obligations, dispute resolution practices, access to information, confidentiality, treatment of shared contracts, any transfers to be completed following the distribution and the receipt of any related third party consents, access to insurance policies, and treatment of outstanding guarantees.

The separation and distribution agreement also sets forth other agreements that govern certain aspects of our relationship with WDC after the completion of the distribution. The parties entered into the separation and distribution agreement immediately before the distribution of Sandisk common stock to WDC stockholders.

Transition Services Agreement

WDC and Sandisk entered into a transition services agreement (the "TSA") which governs the provision of transition services from WDC to Sandisk and from Sandisk to WDC. The TSA specifies the terms under which the transition services are provided. The charges for such services are generally intended to allow the service provider to recover its direct and indirect costs, generally without profit. Contemplated services include: (i) quality assurance, (ii) procurement, (iii) information technology, (iv) logistics management, (v) finance, (vi) human resources, (vii) engineering, (viii) corporate marketing, (ix) central operations, (x) sales operations, (xi) manufacturing, and (xii) research and development. The term of such services is expected to be no longer than eleven (11) months as of the date of this Proxy Statement.

Tax Matters Agreement

In connection with the Separation, WDC and Sandisk entered into a tax matters agreement that governs the parties' respective rights, responsibilities and obligations with respect to tax liabilities and indemnification, tax benefits, tax attributes, the preparation and filing of tax returns, the control of audits and other tax proceedings, tax-free status, and other matters regarding taxes. Pursuant to the tax matters agreement, Sandisk agreed to certain covenants that contain restrictions intended to preserve the tax-free status of the distribution and certain related transactions.

In addition, during the two-year period after the date of the distribution, these covenants include specific restrictions on Sandisk which would be expected to result in the failure to preserve the tax-free treatment of these transactions.

Employee Matters Agreement

WDC and Sandisk entered into an employee matters agreement in connection with the Separation to allocate liabilities and responsibilities relating to employment matters, employee compensation and benefit plans and programs and other related matters. The employee matters agreement also sets forth the general principles relating to employee matters both with respect to domestic and international employees, including with respect to collective bargaining agreements, workers' compensation, payroll matters, regulatory filings, paid time off, commencing or continuing participation in employee benefit plans, and the sharing of employee information. The employee matters agreement also governs the treatment of equity-based awards granted by WDC prior to the distribution and the treatment of WDC's employee stock purchase plan and cash transaction bonus payments.

IP Cross-License Agreement

WDC and Sandisk entered into an IP Cross-License Agreement (the "IPCLA") to facilitate freedom-to-operate with respect to non-trademark intellectual property for each company post-Separation. WDC granted a non-exclusive, worldwide, royalty-free, perpetual license to Sandisk (with respect to retained non-trademark intellectual property held by WDC) within a specified field of use, and Sandisk granted a non-exclusive, worldwide, royalty-free, perpetual license to WDC (with respect to divested non-trademark intellectual property held by Sandisk) within a specified field of use.

Transitional Trademark License Agreement

WDC and Sandisk entered into a Transitional Trademark License Agreement, pursuant to which WDC granted a non-exclusive, worldwide, non-transferable, license to Sandisk (with respect to certain retained trademarks held by WDC), and Sandisk granted a non-exclusive, worldwide, non-transferable, license to WDC (with respect to certain divested trademarks held by Sandisk). These licenses allow each company to rebrand, as necessary, and transition away from the other company's owned trademarks post-Separation, for a specified, limited transitional period.

Stockholder's and Registration Rights Agreement

WDC and Sandisk entered into a stockholder's and registration rights agreement (the "SRRA"), pursuant to which Sandisk agreed that, upon the request of WDC, Sandisk will use its reasonable best efforts to effect the registration under applicable federal and state securities laws of any shares of Sandisk common stock retained by WDC.

In addition, pursuant to this agreement, WDC agreed to vote any shares of Sandisk common stock that it retains immediately after the Separation in proportion to the votes cast by our other stockholders. In connection with such agreement, WDC granted Sandisk a proxy to vote its shares of Sandisk common stock in such proportion. This proxy, however, will be automatically revoked as to any particular share upon any sale or transfer of such share from WDC to a person other than WDC, and neither the SRRA nor proxy will limit or prohibit any such sale or transfer.

Other Related Party Transactions

A child of Luis Visoso, our Executive Vice President and CFO, is employed by our company in a technical product management role with total target compensation of less than $250,000.

Procedures for Approval of Related Person Transactions

Our Board of Directors has established a Related Person Transaction 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) Sandisk was, is 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 will review the transaction to consider whether the transaction should be approved, ratified, or rescinded, or whether other action should be taken. 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 are 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 the 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.

Director Compensation

Fiscal 2025 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 in light of 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 2025 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 the Separation, the WDC Compensation and Talent Committee reviewed an analysis of competitive market data and determined that our non-employee director compensation, which was based on WDC's fiscal 2024 director compensation, was appropriate for fiscal 2025. There are currently no planned changes to the non-employee director compensation program for fiscal 2026.

The following section describes the elements and other features of our director compensation program for fiscal 2025 for non-employee directors.

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 2025.

---

| | |
|:---|:---|
| **Type of Fee** | **Current Annual Fee<br>($)** |
| Annual Retainer | 85000 |
| Additional Committee Member Retainers: |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Audit Committee | 15000 |
| &nbsp;&nbsp;&nbsp;&nbsp;Compensation and Talent Committee | 12500 |
| &nbsp;&nbsp;&nbsp;&nbsp;Governance Committee | 10000 |
| Additional Committee Chair Retainers: |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Audit Committee | 25000 |
| &nbsp;&nbsp;&nbsp;&nbsp;Compensation and Talent Committee | 22500 |
| &nbsp;&nbsp;&nbsp;&nbsp;Governance Committee | 15000 |

---

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. With respect to the initial slate of our non-employee directors, members of the WDC Board of Directors who were appointed to our Board (Ms. Alexy, Mr. Caulfield, Mr. Massengill and Ms. Suzuki) received a pro rata amount of the annual retainer fees based on service to be rendered for the remaining part of fiscal year 2025 after appointment. Mr. Cassidy, Mr. Kumar, Mr. Sayiner, and Ms. Shook received full annual cash retainers.

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 2025 an award of RSUs equal in value to $240,000 (or, in the case of our Lead Independent Director, $280,000). Non-employee directors typically receive the awards immediately following the annual meeting of stockholders if 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. For fiscal 2025, the initial RSU awards were granted shortly after the Separation and were pro-rated for the remaining portion of the year prior to our 2025 Annual Meeting based on the directors' respective appointment dates. The number of RSU awards granted was calculated by dividing the applicable dollar amount by the average closing price of our common stock over the first five full trading sessions, commencing with the first trading session following the effective date of the Separation. On a go-forward basis, the number of RSU awards granted will be calculated by dividing the dollar amount by the closing price of our common stock on the grant date.

The RSUs granted in fiscal 2025 vest 100% upon November 17, 2025 (the date immediately prior to the first annual meeting of stockholders that will be held after the grant date), subject to continued service through that 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 2025 Non-Qualified Deferred Compensation Table."

Director Compensation Table for Fiscal 2025

The table below summarizes the compensation for fiscal 2025 for each of our non-employee directors serving on our Board of Directors in fiscal 2025. Mr. Goeckeler was a named executive officer for fiscal 2025 and did not receive any additional compensation for his services as a director during fiscal 2025. Information regarding his compensation for fiscal 2025 is presented in the "Fiscal 2025 Summary Compensation Table" and the related explanatory tables.

Director Stock Ownership Guidelines

Under our director stock ownership guidelines, directors are generally prohibited from selling any shares of our common stock unless they own "qualifying shares" with a market value of at least $375,000, which include common stock, RSUs, deferred stock units and common stock beneficially owned by the director by virtue of being held in a trust, by a spouse or by the director's minor children. 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. All of our current non-employee directors comply with our director stock ownership guidelines.

A Message From the Compensation and Talent Committee

Dear Stockholders,

2025 marks a historic year and new chapter for Sandisk following our successful separation from Western Digital in February 2025. As Chair of Sandisk's newly formed Compensation and Talent Committee, I am pleased to present our inaugural CD&A, detailing the immediate decisive actions we made following the separation to align executive compensation with our standalone strategy and to drive long-term stockholder value.

Legacy Compensation Decisions Made by Western Digital

Prior to the separation, many elements of fiscal 2025's executive compensation program design, including the entire first half of the year ("1H Fiscal 2025"), were set by Western Digital's Compensation & Talent Committee. Aspects of the executive compensation program that were set by Western Digital, in order to ensure a successful separation and align with market practices, include:

**•** Base salaries for CEO David Goeckeler and CFO Luis Visoso for fiscal 2025

**•** 1H Fiscal 2025 short-term incentive goals, opportunities and payouts, as well as short-term incentive opportunities for the second half of fiscal 2025 ("2H Fiscal 2025")

• Treatment of outstanding Western Digital PSUs and RSUs, which were converted for Sandisk executives on terms consistent with those of Western Digital stockholders

**•** Transaction completion bonuses, payable in cash, for Sandisk executives, with one-year clawback terms

Post-Separation Decisions to Drive a Successful Transition

Following the separation, Sandisk's Compensation and Talent committee implemented a streamlined compensation program for 2H Fiscal 2025 to support critical execution and aggressive stockholder value creation goals. Recognizing the transitional nature of our first year as a standalone company, our compensation approach prioritized clarity, strategic alignment, and a focus on driving excellence.

In Sandisk's first months post-separation, the committee:

**•** Awarded performance-based launch grants to immediately align executives' interests with stockholder interests. The awards are fully contingent upon achieving ambitious stock price hurdles, with no payout unless substantial value is delivered to our stockholders

**•** Introduced clearly defined performance conditions to the 2H Fiscal 2025 short-term incentive program, while allowing flexibility to adapt to the evolving demands of Sandisk's entry into the public markets

**•** Adjusted the base salaries and short-term incentive opportunities for executives Alper Ilkbahar and Bernard Shek in connection with their promotions to critical leadership roles as Executive Vice President & Chief Technology Officer and Senior Vice President & Chief Legal Officer and Secretary, respectively

Compensation Program Evolution

The Compensation and Talent Committee is actively evolving the go-forward compensation program to align with Sandisk's recently established long-term strategic goals to drive sustained value creation. We included information on the fiscal 2026 compensation program design decisions to inform stockholders of where we are headed and solicit their feedback.

We look forward to connecting with many of you as we lay the foundation for Sandisk's future, building a market-leading flash storage company that powers next-generation digital experiences, drives innovation, and delivers long-term value to our stockholders.

Thank you for your continued trust and support as we begin this exciting next chapter for Sandisk together.

Sincerely,

**THE SANDISK COMPENSATION AND TALENT COMMITTEE**

**Ellyn Shook,** Chair

**Necip Sayiner**

**Thomas Caulfield**

Fiscal 2025 Overview

Business Highlights

After a successful separation from WDC, Sandisk launched as an independent, publicly traded company on February 24, 2025. While fiscal 2025, ending on June 27, 2025, reflects only a partial year of standalone operations, our leadership team delivered strong initial results and established a solid foundation for long-term value creation. Amidst a dynamic macroeconomic and industry environment, we delivered strong year-over-year improvements in our top-line and operating results, advanced our strategic priorities, and strengthened our market position as a standalone company.

**Revenue ($B)**<sup>(1)</sup>

![3848290768643](sndk-20251006_g112.jpg)

**Non-GAAP Operating Income ($M)**<sup>(1)</sup>

![12644383802385](sndk-20251006_g113.jpg)

<sup>(1)</sup> Sandisk's revenue and non-GAAP operating income figures represent fiscal 2024 and 2025 figures, which include pre-Separation figures of the flash business unit of WDC. See Appendix A to this Proxy Statement for a reconciliation of GAAP operating income to non-GAAP operating income.

Our results reflect the underlying strength of our business model, the disciplined execution of our executive team through the successful Separation, and our ability to adapt quickly to meet market expectations.

Separation-Related Compensation Decisions

Our Compensation and Talent Committee designed a compensation program for the second half fiscal 2025 ("2H Fiscal 2025") that supported Sandisk's business strategy through the initial post-Separation phase and immediately aligned executive interests with those of our stockholders. The design reflects the strategic intent of the spin-off: to unlock stockholder value by establishing Sandisk as a pure-play leader in flash storage.

Western Digital's Compensation and Talent Committee's oversight of Sandisk's executive compensation programs ended at the Separation. All decisions with respect to the compensation of our named executive officers following the Separation have been made by Sandisk's Compensation and Talent Committee.

2H Fiscal 2025 Executive Compensation Program Design & Elements

Shortly following the Separation from WDC, the Compensation and Talent Committee designed a 2H Fiscal 2025 executive compensation program that closely aligned pay with company performance and the creation of stockholder value, while reflecting our commitment to operational execution and accountability. The committee, with input from its independent compensation consultant, developed our incentive plan structure to ensure the metrics and performance conditions support our business strategy, particularly through the transition to being a standalone company, and align with market norms. The design for 2H Fiscal 2025 is outlined in the summary below.

Sandisk's 2H Fiscal 2025 compensation program includes base salaries, an STI plan and performance-based launch grants LTI awards (for more information, see "Performance-Based Launch Grants Following the Separation" on page [49](#i36aacf7f44c24dd083e898838b5d4dae_110386)). Beyond the performance-based launch grants, the committee did not grant executive officers LTI awards in 2H Fiscal 2025. Executive officers also received limited perquisites and other indirect benefits, described further under "Other Program Features and Policies."

The committee approved a new executive compensation program design for fiscal 2026 to evolve with the long-term goals and strategic priorities set by Sandisk's Board and executive team following the Separation.

Executive Compensation Objectives and Approach

The Compensation and Talent Committee seeks to closely align pay with performance, rewarding executives for delivering results for Sandisk and its stockholders. Our compensation program is designed to offer market-competitive incentives to drive talent retention and incentivize excellence in performance and stockholder value creation. We are committed to setting executive compensation around value-driving metrics, rigorous performance hurdles, and meaningful at-risk pay to ensure accountability and alignment with stockholder interests.

Further, we are committed to compensation program transparency through our disclosures and our forthcoming stockholder engagement program. We value stockholder feedback and view it as a key input in our executive compensation program design and decisions. Our annual stockholder engagement program will ensure stockholder feedback on our compensation practices and approach is presented to and considered by the committee.

For 2H Fiscal 2025, the Compensation and Talent Committee prioritized supporting a successful transition to a standalone company while establishing incentives that aligned our executives with Sandisk's strategy and stockholder value creation immediately post-separation. For more information, see "2H Fiscal 2025 Executive Compensation Program Decisions and Outcomes" on page [46](#i114f29450cd44bb4a6e3ecaf5327c40e_1505).

The committee also began to design our fiscal 2026 compensation program to evolve with the strategic, financial and operational objectives set by Sandisk, beyond the transitional needs of Sandisk's initial months as an independent company. For more information, see "Fiscal 2026 Compensation Program Design and Changes" on page [51](#i114f29450cd44bb4a6e3ecaf5327c40e_1523).

Process for Determining Executive Compensation

Annual Review and Oversight

The Compensation and Talent Committee sets a process to annually review and approve executive compensation design, including base salary, short-term incentives, long-term equity awards, and performance goals, to ensure that pay outcomes reflect company performance and individual contributions. The committee is committed to the evaluation of executive performance against the conditions set within the compensation program on an annual basis and at the time of hiring, promotion or other change in responsibilities. The committee is supported by an independent compensation consultant, regularly benchmarks compensation practices against a carefully selected peer group, and reviews succession and talent development strategies. The committee values the views and input of our stockholders and plans to solicit their feedback as a key input to their decision-making.

In March 2025, the committee established the 2H Fiscal 2025 compensation program to align executives with Sandisk's strategic objectives as a standalone company and its stockholders as management guided our company through the transition.

The Compensation and Talent Committee is evolving the fiscal 2026 compensation program design to ensure alignment with our longer-term strategy and outlook and long-term stockholder value creation. The committee met in May 2025 and twice in August 2025 to consider fiscal 2026 design with input from its independent advisor and in reviewing compensation practices among our peers. Management and the committee worked to evolve the program in fiscal 2026 to align with our strategic objectives and incorporate metrics identified by many of our investors as material factors in evaluating us. For more information, see "Fiscal 2026 Compensation Program Design & Decisions" on page [51](#i114f29450cd44bb4a6e3ecaf5327c40e_1523).

Committee Responsibilities and Governance Framework

The Compensation and Talent Committee is responsible for carrying out the Board's oversight relating to the compensation of our company's executive officers and our company's broader talent strategy. In accordance with its charter, the committee's responsibilities include:

**•** Oversight of executive and director compensation program design and related policies

**•** Evaluation of executive performance and resulting payouts

**•** Creation of the CD&A for inclusion in the annual proxy statement

**•** Periodic review of our company's people policies, programs, and initiatives

**•** Planning executive succession processes and senior leadership development

**•** Oversight of employee benefit plans

**•** Communicating to stockholders our company's executive compensation philosophy, policies, and programs

The committee operates under a written charter approved by the Board, which is reviewed annually and available at **investor.sandisk.com**. Each member of the committee has been determined by the Board to be independent under applicable Nasdaq and SEC rules.

Process for Determining Executive Compensation

In determining our executive compensation program design, the Compensation and Talent Committee's executive compensation decisions are informed by several factors, including:

---

| |
|:---|
| &nbsp;&nbsp;**External and Internal Factors** |
| &nbsp;&nbsp;&nbsp;&nbsp;**•** Our pay positioning relative to our proxy peer group and broad compensation survey market data<br>&nbsp;&nbsp;&nbsp;&nbsp;**•** Our goal to drive meaningful value creation post-separation and ensure a successful transition to operating as an independent company<br>&nbsp;&nbsp;&nbsp;&nbsp;**•** The executive officer's role, experience, performance and contributions<br>&nbsp;&nbsp;&nbsp;&nbsp;**•** Our retention objectives<br>&nbsp;&nbsp;&nbsp;&nbsp;**•** Succession planning<br>&nbsp;&nbsp;&nbsp;&nbsp;**•** Company performance and strategic and financial goals<br>&nbsp;&nbsp;&nbsp;&nbsp;**•** Market performance and general economic conditions |
| &nbsp;&nbsp;**Management** |
| &nbsp;&nbsp;&nbsp;&nbsp;**•** Our CEO's recommendations for select executive officers' promotions, responsibilities and performance expectations <br>&nbsp;&nbsp;&nbsp;&nbsp;**•** Our CFO's input on financial targets for our performance-based incentive compensation program<br>&nbsp;&nbsp;&nbsp;&nbsp;**•** Internal and external compensation data provided by our human resources team |
| &nbsp;&nbsp;**Compensation Consultant** |
| &nbsp;&nbsp;&nbsp;&nbsp;**•** Independent insights on compensation program design<br>&nbsp;&nbsp;&nbsp;&nbsp;**•** Compensation survey and proxy peer group data |
| &nbsp;&nbsp;**Stockholders** |
| &nbsp;&nbsp;&nbsp;&nbsp;**•** Feedback from our planned stockholder outreach and engagement program  |

---

Role of the Compensation Consultant

Post-Separation, the Compensation and Talent Committee engaged Pay Governance LLC ("Pay Governance") as its independent compensation consultant. Pay Governance reported directly to the committee and communicated with management to gather information and review management proposals as needed. Pay Governance attended all regularly scheduled meetings of the committee during 2H Fiscal 2025 and its responsibilities post-Separation generally included:

**•** Reviewing and advising on executive compensation, including the performance metrics used under the executive compensation program

**•** Reviewing and advising on performance-based launch grants designed to drive meaningful value creation and incentivize strategic execution during Sandisk's critical early years as an independent company

**•** Providing recommendations regarding the composition and selection of our proxy peer group companies

**•** Analyzing proxy peer group and survey compensation data

**•** Providing advice regarding executive compensation policies, practices and trends

The Compensation and Talent Committee assessed the independence of Pay Governance pursuant to applicable rules and regulations of the SEC and the Nasdaq Stock Market and concluded that the engagement of Pay Governance did not raise any conflicts of interest during fiscal 2025 and currently does not raise any conflicts of interest. No other fees were paid to Pay Governance except fees related to its services to the committee.

Comparative Market Data

The Compensation and Talent Committee determines the composition of our proxy peer group and will reevaluate this group on an annual basis with input from its independent compensation consultant.

The Compensation and Talent Committee, with the assistance of Pay Governance, conducted a thorough review of the peer group used for executive compensation benchmarking. The committee reviews proxy peer group executive compensation data provided by Pay Governance and independently published compensation survey data from the Aon Radford McLagan Compensation Database.

With input from its independent compensation consultant, the committee considers such market data and industry practices during its review of our executives' compensation levels and mix of compensation elements.

Fiscal 2025 Proxy Peer Group Companies for Benchmarking Pay and Incentive Design

The proxy peer group companies that the Compensation and Talent Committee used for comparative pay and incentive design purposes for 2H Fiscal 2025 consisted of technology companies that compete with Sandisk for talent and are comparable to our company's size, primarily based on revenue, and other relevant business characteristics. The committee believes that providing a compensation package that is competitive – particularly relative to our peer group – allows us to attract, motivate, reward, and retain the talent needed to drive long-term stockholder value.

Specifically, the following criteria were used to select our peer set:

**• Size/scope:** revenue 1/3x to 3x; market cap 1/5x to 5x

**• Competition:** competes with Sandisk's lines of businesses and/or for talent

**• Industry:** operates primarily in data storage or semiconductor industry (in SOX Index) or more broadly within the Information Technology industry

**• Other Considerations:** global footprint, listing on a major U.S. exchange with disclosed executive pay practices; well-known technology and/or consumer brands

Not all peer companies will meet each of the selection criteria above. Size criteria may sometimes be relaxed for companies that are strong fits in terms of talent and business focus.

After the Separation, the committee worked with Pay Governance and management to develop a peer set that reflects Sandisk's size, business, and market profile. The committee prioritized the inclusion of companies that are competitive in our talent market and have comparable revenue. Revenue is a commonly used proxy for organizational size and complexity and is typically stable from year-to-year, making it a valuable metric when selecting peers for executive compensation purposes. As part of its decision process, the committee also referenced other metrics for informational purposes, including comparative market capitalization and profitability metrics.

Following its review, the Compensation and Talent Committee determined a peer set of 17 companies that is most relevant to Sandisk based on the above criteria.

2H Fiscal 2025 Executive Compensation Program Decisions and Outcomes

Base Salary

The Compensation and Talent Committee closely reviews executive base salaries to ensure each are market-competitive, support retention and reflect expectations for role and performance.

Before the Separation, base salaries for fiscal 2025 for Mr. Goeckeler and Mr. Visoso were set and approved by Western Digital's Compensation and Talent Committee to reflect their roles, responsibilities and market-competitive rates.

Effective March 10, 2025, the committee approved compensation adjustments for Alper Ilkbahar in connection with his promotion to Executive Vice President and Chief Technology Officer and for Bernard Shek in connection with his promotion to Senior Vice President and Chief Legal Officer and Secretary. In recognition of both officers' increased titles, roles and responsibilities, as well as competitive market rates for their positions, Mr. Ilkbahar's base salary was raised from $575,000 to $625,000 and Mr. Shek's was increased from $375,000 to $425,000 on an annual basis.

<sup>(1)</sup> Table reflects annualized base salary in effect at the end of fiscal 2025 for each named executive officer. The base salaries reflected in the Summary Compensation Table reflect amounts paid after the Separation.

2H Fiscal 2025 Executive STI

In anticipation of the Separation, WDC's Compensation and Talent Committee designed fiscal 2025 Executive STI plan (the "Executive STI") on a six-month basis. Prior to Separation, WDC set 1H Fiscal 2025 STI opportunities, goals and payouts, as well as 2H Fiscal 2025 STI opportunities, given the Separation was effective after 1H Fiscal 2025. The Sandisk Compensation and Talent Committee decided 2H Fiscal 2025 STI performance conditions and payouts. The committee also retained Mr. Goeckeler's and Mr. Visoso's STI opportunities from 1H Fiscal 2025 and increased STI opportunities for Mr. Ilkbahar and Mr. Shek.

In March 2025, the Sandisk Compensation and Talent Committee increased Mr. Ilkbahar's annual target STI opportunity from 80% to 100%, and Mr. Shek's annual target STI opportunity from 75% to 80%, in connection with their post-Separation promotions.

2H Fiscal 2025 Executive STI Performance Conditions

For 2H Fiscal 2025, the Compensation and Talent Committee determined that our executives should be focused on a successful transition and introduction to the public markets. The committee prioritized sustainable profitability and top-line growth as critical to these goals. The committee also sought to ensure the STI design granted flexibility to incentivize and reward executives based on their performance against evolving expectations in our company's first months as a standalone business. The 2H Fiscal 2025 Executive STI program was based on two equally weighted financial metrics: non-GAAP operating income (50%) and revenue (50%), as well as an individual performance modifier (+/- 25%).

The 2H Fiscal 2025 Executive STI program applied to all named executive officers and provided cash payouts based on company-wide performance against targets established in March 2025 and individual performance goals evaluated on a continual basis during the period.

2H Fiscal 2025 Executive STI Performance

The STI plan for 2H Fiscal 2025 funded at 139.9% of performance relative to metrics approved by our Compensation and Talent Committee. Specifically, 150% for non-GAAP Operating Income and 130% for Revenue payout components. However, the Compensation and Talent Committee, based on a recommendation from management, utilized negative discretion to lower funding to 90% of target for the corporate performance component to balance great execution by our company with the fact that our company did not generate a profit in 2H Fiscal 2025.

2H Fiscal 2025 Executive STI Individual Performance Modifier

Performance Assessment

Our individual performance modifier is designed to recognize our executives' role-specific impact not fully captured in the financial metrics of our STI program, particularly as we navigated through our initial months as a standalone company. The individual performance modifier for each executive officer's target incentive award opportunity reflects input from our CEO and Compensation and Talent Committee, which was discussed during its executive session on August 4, 2025.

The overall impact of the Compensation and Talent Committee's approved STI individual performance modifiers was under $63,000 across the named executive officers, representing approximately 3% of the overall Executive STI payout to our named executive officers.

The committee did not apply a modifier to Mr. Goeckeler's STI payout.

At Mr. Goeckeler's recommendation, the committee applied a +5% modifier to Mr. Visoso's STI payout to reflect his leadership role within Sandisk following the Separation, including his key role in supply allocation and pricing strategy. Mr. Visoso continues to drive accountability within the finance and sales functions that is reflected in the company's financial performance.

At Mr. Goeckeler's recommendation, the committee applied a +10% modifier be applied to Mr. Ilkbahar's STI payout to recognize his critical leadership within the NAND team as Sandisk stands up as a separate company. Mr. Ilkbahar's technology roadmap, including the development of high-bandwidth flash, contributes to Sandisk's continued leadership in innovation.

At Mr. Goeckeler's recommendation, the committee applied a +5% modifier be applied to Mr. Shek's STI payout to reflect his strong execution in the Separation and the establishment of Sandisk's legal team and functions. Mr. Shek supported cross-border operations by navigating regulatory and trade compliance in multiple jurisdictions and managed litigation matters and government inquiries.

As a result of the committee's individual performance determinations, our named executive officers received the following payout amounts under the Executive STI plan:

The Compensation and Talent Committee continues to evaluate the Executive STI design and made decisions to evolve the fiscal 2026 design to align with Sandisk's long-term value creation and strategic goals, as set by management post-Separation. Fiscal 2026 Executive STI design incorporates initial feedback from stockholders on financial measures important to them and our Board looks forward to soliciting stockholder feedback on the revised program in the year ahead. For more information, see the section "Fiscal 2026 Compensation Program Design & Decisions" on page [51](#i114f29450cd44bb4a6e3ecaf5327c40e_1523).

Treatment of Outstanding Western Digital Equity Awards

Pursuant to the Employee Matters Agreement between WDC and Sandisk, effective February 21, 2025, outstanding unvested WDC equity awards held by executives who are employed by Sandisk following the Separation – including Mr. Goeckeler, Mr. Visoso, Mr. Ilkbahar, and Mr. Shek – were converted into time-based RSUs denominated in both WDC and Sandisk shares in a ratio of one Sandisk RSU for every three WDC RSUs held at Separation (the "Basket Approach"). All outstanding WDC PSU awards, including those granted by WDC for the fiscal 2023–2025, fiscal 2024–2026, and fiscal 2025-2027 performance periods, were converted to time-based RSUs denominated in both Sandisk and WDC shares using the Basket Approach ratio. All of these awards will vest contingent on continued service with Sandisk through the applicable vesting dates.

Please refer to the Outstanding Equity Table on page [55](#i114f29450cd44bb4a6e3ecaf5327c40e_1625) for more information.

Performance-Based Launch Grants to Drive Value Creation

Rationale

In March 2025, the Compensation and Talent Committee approved performance-based launch grants (the "Launch Grants") to key executives to align our executives with stockholder interests and drive long-term value creation of the new, standalone company. The Launch Grants are non-recurring and will not be granted on an annual basis. The performance-based Launch Grants were the optimal solution for the committee's many considerations for 2H Fiscal 2025 LTI awards, including the following considerations:

**• Executive Focus in Critical Transition Period:** The awards were designed to motivate our newly established leadership team to deliver on ambitious stock price goals during the first three years following the Separation.

**• LTI Compensation:** In the absence of a formalized LTI program immediately following the Separation, the Launch Grants fulfill the committee's goal of rewarding executives with equity subject to long-term performance conditions.

**• Market Practice:** The committee reviewed peer and market data with its independent compensation consultant and noted that many recent spin-offs granted performance-based launch equity to senior executives.

**• Alignment with Sandisk:** Given our named executive officers were former WDC employees and their equity compensation - both from prior years and for fiscal 2025 - was subject to a stock conversion methodology in-line with our investors, the committee elected to increase the portion of at-risk equity denominated in Sandisk shares for the executive team in embarking on this next chapter as a standalone company.

**• Alignment with Stockholders:** The awards are 100% performance-based and directly link executive pay with stockholder value creation. Executives receive no payout unless stockholders also experience meaningful gains.

**• Rigorous Performance Goals:** The Launch Grants were designed with rigorous stock price performance requirements, such that executives are rewarded only for sustained and significant stockholder value creation.

**• Retention and Continuity:** These one-time awards support the retention of key executive talent during a transformative period, with settlement deferred until the end of the performance period.

**• Governance Safeguards:** The Launch Grants are subject to a three-year performance and settlement period, interpolation and banking mechanics, change-in-control protections, a service requirement, and our clawback policy.

Design & Structure

The Launch Grants are 100% performance-based and contingent on aggressive stock price hurdles that require executives to deliver substantial value to stockholders over a multi-year period to earn any payout.

No value is delivered unless our stock price increases materially from our average five-day closing price immediately following the Separation ($47.07 per share). Payouts require sustained and exceptional stock appreciation for a period of ninety trading days. To achieve the maximum payout of 300% of target PSUs, the stock must reach a 125% increase, or $105.91, sustained over a rolling 90-trading-day average. These requirements create a high-performance threshold for any upside to be realized by our executives. The rolling 90-trading day closing stock price averages during the performance period ensure that only sustained, not temporary, stock price performance is rewarded.

The target grant value for each of the Launch Grants participants was carefully set based on (1) market practices in spin-off equity award size; (2) individual post-Separation Sandisk ownership level and unvested equity holding values; and (3) participant's prior annual grant levels.

The grant date for the Launch Grants was May 9, 2025 and the awards cover a three-year performance period from March 3, 2025 through February 24, 2028. At each fiscal year end, awards will be earned based on the highest level of achievement (either at threshold or interpolation between thresholds) for the look-back period. Any earned PSUs will be settled at the end of the performance period.

Finally, no PSUs will vest unless at least the threshold performance is achieved (see details below).

Potential Executive Launch Grant Share of Total Market Capitalization Gain at Max Performance

The potential compensation expense related to the Launch Grants represents a very small percentage of Sandisk's market capitalization gain at each performance tier.

The following chart illustrates that if Sandisk named executive officers achieve maximum performance under the Launch Grant plan, their combined payout would represent only about 1.9% of the total $8.55 billion in market capitalization gain created for stockholders, calculated using the number of shares of common stock outstanding as of the close of business on May 5, 2025, as disclosed on Form 10-Q for the quarter ended March 28, 2025 filed with the SEC on May 12, 2025.

Performance-Based Launch Grant Values and Participants

The Compensation and Talent Committee approved the Launch Grants for our named executive officers, with targets and intended grant values as follows:

---

| | |
|:---|:---|
| **Named Executive Officer** | **Total Target**<br>**Grant Value**<br>**($)**<sup>(1)</sup> |
| **David V. Goeckeler** | 12000000 |
| **Luis F. Visoso** | 4500000 |
| **Alper Ilkbahar** | 1875000 |
| **Bernard Shek** | 743750 |

---

<sup>(1)</sup> The Summary Compensation Table reflects the accounting grant date fair value of the Launch Grants that is different from the intended target grant value shown above.

Transaction Completion Awards

In connection with the Separation, on January 25, 2025, WDC approved and funded the Transaction Completion Awards to Mr. Goeckeler, Mr. Ilkbahar, and Mr. Shek, in an amount equal to 24 times then-current monthly base salary for Mr. Goeckeler and 18 times then-current monthly base salaries for Mr. Ilkbahar and Mr. Shek. Mr. Visoso, who joined WDC shortly before the Separation, was not eligible to receive a Transaction Completion Award. The Transaction Completion Awards are subject to clawback terms for 12 months following the Separation in the event of a voluntary termination. The awards required the participants to be employed by Sandisk following the completion of the Separation and were therefore paid by Sandisk (although funded by WDC).

Fiscal 2026 Compensation Program Design and Decisions

The Compensation and Talent Committee evolved our fiscal 2026 compensation program design to promote alignment with our longer-term strategy and outlook, and to drive long-term stockholder value creation. In our first months as a standalone company, the Compensation and Talent Committee implemented a streamlined compensation program for 2H Fiscal 2025 to maintain leadership's focus on executing a successful transition and introduction to the public markets, while immediately aligning executives with our corporate performance and stockholder value creation. As our leadership established a long-term strategy post-Separation, the committee designed the fiscal 2026 program to support near-term performance, the company's long-term strategic goals, and the creation of long-term stockholder value.

Fiscal 2026 Base Salary

Effective August 1, 2025, the Compensation and Talent Committee approved an increase in Mr. Shek's base salary from $425,000 to $500,000. In reviewing his compensation, the committee noted that Mr. Shek's base salary was positioned below the 25th percentile of the market, and his total direct compensation was also near the 25th percentile. The increase was intended to bring his base salary closer to market practice and better align his overall compensation with his role and responsibilities. No other base salary adjustments have been made.

Fiscal 2026 STI Design

For fiscal 2026, the Compensation and Talent Committee evolved the STI design to directly align executive compensation with our strategic priorities and drive near-term financial and operational performance. These priorities were established by our leadership post-Separation, and the fiscal 2026 program was developed to support and reinforce those objectives. We also took stockholder feedback into account when selecting these metrics. The committee selected:

**•** Profit Metrics (50%): Includes Non-GAAP Operating Income and Non-GAAP Operating Margin, chosen to incentivize profitability and efficient management of expenses

**•** Adjusted Free Cash Flow (25%): Ensures disciplined cash management and strengthens financial flexibility while mitigating volatility and timing impacts

**•** Corporate Strategy (25%): Equally weighted across Net Debt, Consumer Net Revenue, and Data Center Market Share, selected to drive strategic focus areas critical for long-term market positioning and growth

Fiscal 2026 LTI Design

For fiscal 2026, the Compensation and Talent Committee designed the LTI to align with our long-term strategic objectives and drive sustainable stockholder value creation. The LTI sets Revenue and Earnings Per Share metrics, each weighted at 50% with payouts capped at 200%. Further, the committee adopted a three-year design using three consecutive one-year performance periods. This structure enables the committee to set challenging annual targets responsive to market conditions and industry cycles. Annual vesting percentages will be calculated separately and averaged at the end of the three-year cycle to determine the final vesting percentage, reinforcing sustained long-term performance over three-year periods.

Fiscal 2026 LTI Awards

The Compensation and Talent Committee granted the following LTI awards to our named executive officers in fiscal 2026, as part of our annual LTI program:

Other Program Features and Policies

Perquisites

We provide our executive officers with only limited perquisites and other personal benefits, consisting principally of a $5,000 annual allowance for financial planning services (net of taxes).

Our policy permits Mr. Goeckeler (in his capacity as CEO) to use private aircraft, in which we have a fractional ownership interest, for personal travel to maximize his business availability, productivity, and to take into account security considerations. Mr. Goeckeler is required to reimburse the company for the aggregate incremental cost incurred by the company in connection with any such personal 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

Our executive officers are eligible to participate in 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 or supplemental retirement plans for our executive officers.

Deferred Compensation Opportunities

Our executive officers who are subject to U.S. federal income taxes are eligible to participate in our Deferred Compensation Plan. Under the plan, participants can elect to defer certain compensation without regard to the tax code limitations applicable to tax-qualified plans.

Severance Protections

Our executive officers are eligible to participate in our Executive Severance Plan. Outside a change in control context, we view severance protections as only appropriate in the event the employment of an executive officer is involuntarily terminated without "cause."

Change in Control Protections

To encourage our executive officers to remain employed during an important time when their prospects for continued employment following a change in control transaction are often uncertain, we provide our executive officers with additional severance protections under our change in control severance plan (the "Sandisk CIC Severance Plan"). Benefits under the Sandisk CIC Severance Plan require a "double-trigger" (a qualifying termination in connection with a change in control) for payment and the plan does not provide any tax gross-up payments for participants.

Clawback Policy

The Board of Directors adopted a compensation recovery (clawback) policy consistent with the requirements of Rule 10D-1 under the Exchange Act and Nasdaq Listing Standards, a copy of which is publicly filed with our 2025 Annual Report on Form 10-K.

Employment Agreements

WDC entered into an offer letter dated July 1, 2024 with our Chief Financial Officer, Mr. Visoso. The offer letter provided that

Mr. Visoso's employment with WDC would transfer to Sandisk in connection with the Separation. Our other executive officers are not currently party to an employment agreement with Sandisk.

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 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 Transaction

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 Sandisk'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 Sandisk's securities, shorts sales, transactions in derivative securities, such as publicly traded options, related to Sandisk's securities and margining Sandisk's securities in a margin account or otherwise pledging Sandisk securities as collateral for a loan.

Executive Stock Ownership Guidelines

We maintain executive stock ownership guidelines covering our executive officers, including our named executive officer, 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 "qualifying shares" 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.

---

| | |
|:---|:---|
| **Position** | **Multiple** |
| CEO | 6 x Salary |
| CFO | 3 x Salary |
| Executive Vice Presidents | 2 x Salary |
| Senior Vice Presidents | 1 x Salary |

---

Each executive officer must achieve ownership of the required market value of shares within three years of becoming subject to the guidelines. Common stock, RSUs, PSUs, and common stock beneficially owned by the executive officer all count towards the requirement but shares the officer has a right to acquire through exercising stock options (whether or not vested) are not counted.

Equity Grant Timing

Annual equity awards are generally made in late August or early September each year and the Compensation and Talent Committee may also consider and approve interim or mid-year grants from time to time based on business needs. We do not currently grant stock options to our employees. The committee does not take material non-public information into account when determining the timing and terms of LTI awards and has not timed the disclosure of material non-public information for the purpose of affecting the value of executive compensation.

<sup>(1)</sup> Salaries reflect salary paid from the date of the Separation (February 21, 2025) through the end of fiscal 2025.

<sup>(2)</sup> In connection with the Separation, WDC approved and funded the Transaction Completion Awards to certain named executive officers, which are subject to repayment terms for 12 months following the Separation in the event of a voluntary termination. Please see the section entitled "Transaction Completion Awards" above for further information. For the avoidance of doubt, Mr. Goeckeler received only one Transaction Completion Award of $2.6 million.

<sup>(3)</sup> 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 12 in the Notes to Consolidated Financial Statements included in our 2025 Annual Report on Form 10-K. For PSU awards, amounts reflect the grant date fair value of the Launch Awards.

The following amounts represent the grant date fair value of PSU awards granted to our named executive officers during 2H fiscal 2025. We considered the probable outcome of the awards and maximum performance under the awards based on a Monte Carlo simulation. 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.

<sup>(1)</sup> The amounts shown reflect the grant date fair value of the award computed in accordance with ASC 718. These amounts were calculated based on the assumptions described in Note 12 in the Notes to Consolidated Financial Statements included in our 2025 Annual Report on Form 10-K. The grant date fair value for the Launch Grants, at the probable outcome, is based on the value of our common stock on May 9, 2025 using a Monte Carlo simulation, which resulted in a simulated award value of $59.27 per share based on certain assumptions.

<sup>(2)</sup> Represents the Launch Grants, covering the period beginning March 3, 2025, and ending on February 24, 2028, based on our achievement of stock price goals, as determined by the Compensation and Talent Committee, that correspond to specific payout percentages ranging between 0% to 300% of the target number of stock units subject to the award. Earned PSUs will vest on February 24, 2028, subject to the named executive officer's continuous service.

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 2025 Grants of Plan-Based Awards Table" was granted by the Compensation and Talent Committee under, and is subject to, the terms of our 2025 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 2025 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 June 27, 2025. The amount shown for the market value of the stock awards is based on the closing price of our common stock on June 27, 2025 ($47.15).

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:

**•** "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

**•** "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

**•** "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:

**•** A 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

**•** 100% 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)

**•** A 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).

**•** A lump sum cash payment of the executive officer's monthly base salary multiplied by 24 months

**•** Any 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, assuming target performance

**•** For 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

**•** For RSU awards, acceleration of vesting of a prorated amount of RSUs

**•** Outplacement services at our expense for 12 months following the executive officer's termination of employment

**•** A 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

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.

In the event of a qualified 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.

No RSUs contain an acceleration benefit for an eligible retirement.

Death

In the event of an executive officer's death, 50% of the outstanding RSUs will accelerate.

For RSUs and PSUs assumed from WDC in connection with the Separation: (1) the vesting of a pro rata portion of WDC RSUs granted prior to its fiscal 2025 grant and a pro rata portion of WDC PSUs will accelerate; and (2) 50% of the outstanding RSUs will accelerate upon an executive officer's death for WDC fiscal 2025 grants.

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. Goeckeler, Visoso, Ilkbahar, and Shek under the arrangements described above based on the following assumptions:

**•** Qualifying termination of employment and/or change in control occurred on June 27, 2025

**•** The price per share of our common stock is equal to the closing price of our common stock on June 27, 2025 ($47.15), the last trading day in fiscal 2025

**•** In 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

**•** Not included in the table below are payments each named executive officer earned or accrued prior to termination, such as previously vested equity and non-equity incentive awards, which are more fully described and quantified in the tables and narratives above

<sup>(1)</sup> 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.

<sup>(2)</sup> 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. Our named executive officers would not be required to repay the Transaction Completion Bonuses granted by WDC in connection with the Separation in this involuntary termination scenario.

<sup>(3)</sup> As of June 27, 2025, only Mr. Ilkbahar met the requirements for a "qualified retiree" with respect to PSUs.

<sup>(4)</sup> The amounts shown are based on the intrinsic value of the portion of the RSU award that would have accelerated as of June 27, 2025. These intrinsic values were based on the closing price of our common stock on June 27, 2025 ($47.15).

<sup>(5)</sup> 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 June 27, 2025. These intrinsic values were calculated by multiplying (i) the closing price of our common stock on June 27, 2025 ($47.15), by (ii) the target number of PSUs or, if applicable, the credited amount, that would have remained outstanding and eligible to vest as of June 27, 2025. The Launch Grants would not have met the stock price performance threshold and therefore excluded from these values.

<sup>(6)</sup> For purposes of these calculation, 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.

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 "Compensation Discussion and Analysis" beginning on page [38](#i114f29450cd44bb4a6e3ecaf5327c40e_335).

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 2025 Summary Compensation Table" above; (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.

<sup>(1)</sup> The PEO was Mr. Goeckeler for fiscal year 2025. The Other NEOs were: Messrs. Visoso, Ilkbahar, and Shek. The dollar amounts reported are the amounts reported for the PEO, or the average of the amounts reported for the Other NEOs, in the "Total" column in our applicable Summary Compensation Table.

<sup>(2)</sup> 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. 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 executives, 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.

The amounts shown with respect to our Other NEOs are the average amounts for such Other NEOs, as a group.

<sup>(3)</sup> 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.

The net income amounts for fiscal years 2022 and 2023 have been updated to reflect the revised amounts, as a result of the restatement of previously reported financial information to certain errors we identified during fiscal 2024 as described in the section entitled "Compensation Recovery Determination" above.

Financial Performance Measures

As described in greater detail under "Compensation Discussion and Analysis," the metrics that we use for our 2H Fiscal 2025 STI program were 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 2H Fiscal 2025 are as follows:

**•** Revenue

**•** Non-GAAP Operating Income

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

As described in greater detail under "Compensation Discussion and Analysis," our executive compensation programs reflect strong pay-for-performance alignment. A significant portion of our 2H Fiscal 2025 target compensation awarded to our named executive officers was at-risk, contingent on both company and individual performance against rigorous goals set under our Executive STI plan and Launch Grants.

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.

2025 CAP to our PEO of $40.8 million is higher than the Summary Compensation Table figure of $22.9 million, and the average CAP for our Other NEOs of $8.5 million is higher than the Summary Compensation Table average of $4.8 million. Net loss for 2025 was $1,641 million and Revenue for 2025 was $7,355 million.

| **(→)** | Our Board of Directors recommends a vote to hold future advisory votes on named executive officer compensation every ONE YEAR. |

Proposal Details

In accordance with the requirements of Section 14A of the Exchange Act and the related rules of the SEC, we are asking our stockholders to vote, on a non-binding, advisory basis, for their preference as to how frequently we should seek future advisory votes on the compensation of our named executive officers. By voting with respect to this Proposal 3, stockholders may indicate whether they would prefer that we conduct future advisory votes on executive compensation every one, two, or three years. Stockholders also may, if they wish, abstain from voting on this Proposal 3.

Board Recommendation and Vote Required for Approval

Board Recommendation

Our Board of Directors recommends that you vote, on a non-binding advisory basis, to hold future advisory votes on named executive officer compensation every ONE YEAR (as opposed to every two or every three years) so that stockholders may annually express their views on our executive compensation program. The Compensation and Talent Committee, which administers our executive compensation program, values the opinions expressed by stockholders in these votes and will consider the outcome of these votes in making future decisions on executive compensation. Stockholders are not voting to approve or disapprove our Board of Directors' recommendation.

Vote Required for Approval

The affirmative vote of holders of a majority of the outstanding shares of common stock represented in person or by proxy at the Annual Meeting and entitled to vote on this proposal is required to approve, on a non-binding advisory basis, a frequency option for future advisory votes on executive compensation. You may vote for ONE YEAR, TWO YEARS, THREE YEARS or ABSTAIN on this proposal. Proxies received by our Board of Directors will be voted for **ONE YEAR** on this Proposal 3 unless specified otherwise. If no frequency option receives the affirmative vote of holders of a majority of the outstanding shares of common stock represented at the meeting, our Board of Directors will consider the option receiving the highest number of votes as the preferred option of our stockholders.

While this vote is nonbinding on our company and our Board of Directors, our Board and Compensation and Talent Committee value the opinions of our stockholders and will consider the outcome of this proposal when determining how frequently to conduct advisory votes on named executive officer compensation.

AUDIT COMMITTEE MATTERS

| **(→)** | **•** Our 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 2026<br>**•** We 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 |
| **(→)** | &nbsp;&nbsp;Our Board of Directors recommends a vote FOR the appointment of KPMG LLP as our independent registered public accounting firm for fiscal 2026 |

---

KPMG LLP has served as our independent auditors since 2025. The Audit Committee has again appointed KPMG LLP to serve as our independent registered public accounting firm for the fiscal year ending July 3, 2026. 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 outstanding shares of 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.

The following table presents the fees paid by us to KPMG LLP for fiscal year 2025, the first year we operated as an independent public company. We did not pay any fees for professional services to KPMG LLP in 2024. Prior to the Separation from WDC, we did not separately engage an independent registered public accounting firm, and WDC paid any audit, audit-related, tax, or other fees related to Sandisk's business:

---

| | | |
|:---|:---|:---|
| **Description of Professional Service** | **Fiscal 2025**<br>**($)** | **Fiscal 2024**<br>**($)** |
| **Audit Fees** — professional services rendered for the audit of our annual financial statements and the review of the financial statements included in our Quarterly Reports on Form 10-Q or services that are normally provided in connection with statutory and regulatory filings or engagements | 2202292 | N/A |
| **Audit-Related Fees** — assurance and related services reasonably related to the performance of the audit or review of our financial statements<sup>(1)</sup> |  | N/A |
| **Tax Fees** — professional services rendered for tax compliance, tax advice and tax planning<sup>(2)</sup> | 137405 | N/A |
| **All Other Fees** — products and services other than those reported above |  | N/A |

---

<sup>(1)</sup> Audit-Related Fees for fiscal 2025 consisted of assurance and review services related to the Separation and the secondary offering of WDC's holdings in our company.

<sup>(2)</sup> Tax Fees in fiscal 2025 consisted of tax compliance assistance and related services and transfer pricing review.

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 committee. KPMG LLP periodically reports to the committee regarding the extent of services provided in accordance with this pre-approval and the fees for the services performed to date. The committee may also delegate to a subcommittee the authority to pre-approve audit and permissible non-audit services and associated fees that were not pre-approved by the committee, up to a maximum amount of fees per audit or permissible non-audit service. The subcommittee is required to report any decisions to pre-approve such audit or non-audit services and fees to the full committee at its next regular meeting. All services performed by KPMG LLP during fiscal 2025 were pre-approved by the 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 outstanding shares of common stock represented in person or by proxy at the Annual Meeting and entitled to vote on this Proposal 4 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 will be voted **FOR** this Proposal 4 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 June 27, 2025. This report shall not be deemed to be 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 Sandisk and its subsidiaries, and has general responsibility for oversight and review of the accounting and financial reporting practices, internal controls and accounting and internal and external audit activities of Sandisk 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 originally adopted the Audit Committee Charter on January 25, 2025. A copy of the charter is available on our website under "Governance" at **investor.sandisk.com**. Our Board has determined that each of the members of the Audit Committee is an "audit committee financial expert" as defined by the SEC and 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 Sandisk's financial statements, the financial reporting process, accounting principles and internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. KPMG LLP, Sandisk's independent registered public accounting firm since 2025, is responsible for performing an independent audit of Sandisk'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 Sandisk's independent registered public accounting firm and regularly solicits and evaluates 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 following the fiscal 2030 audit.

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 accounting principles generally accepted in the United States 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 2025, the Audit Committee met a total of four times. During fiscal 2025, the Audit Committee also met and held discussions with management and KPMG LLP. The meetings were conducted so as 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, Sandisk's internal control over financial reporting and the overall quality of Sandisk's accounting practices. As part of these discussions, the Audit Committee reviewed and discussed the audited consolidated financial statements of Sandisk for the fiscal year ended June 27, 2025 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.

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 has recommended to our Board that the audited financial statements be included in Sandisk's Annual Report on Form 10-K for the fiscal year ended June 27, 2025, for filing with the SEC. The Audit Committee also appointed KPMG LLP to serve as Sandisk's independent registered public accounting firm for the fiscal year ending July 3, 2026. 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 Sandisk and its stockholders.

ADDITIONAL INFORMATION

General Information About the Annual Meeting

Virtual Annual Meeting

The Annual Meeting will be a completely virtual meeting of stockholders conducted via live audio webcast to enable our stockholders to participate from any location around the world. You will be able to attend the Annual Meeting by visiting **www.virtualshareholdermeeting.com/SNDK2025**.

Attendance and Participation at the Virtual Annual Meeting

**•** We believe that the virtual annual meeting format will give stockholders the opportunity to exercise the same rights as if they had attended an in-person meeting and believe that these measures will enhance stockholder access and encourage participation and communication with our Board of Directors and management by enabling all stockholders to participate fully, equally and without cost, using an Internet-connected device from any location around the world. In addition, the virtual annual meeting format increases our ability to engage with all stockholders, regardless of size, resources or physical location.

**•** Attendance at the Annual Meeting is open to the public online at **www.virtualshareholdermeeting.com/SNDK2025**, but only stockholders of record or beneficial owners as of September 22, 2025, the record date, or those holding a valid legal proxy for the Annual Meeting are entitled to vote or ask questions via the online virtual annual meeting platform.

**•** To participate in the Annual Meeting by voting or asking questions, you will need the control number included on your Notice of Internet Availability of Proxy Materials, on your proxy card or on the instructions that accompanied your proxy materials.

**•** We will have technicians ready to assist you with any technical difficulties you may have accessing the Annual Meeting. If you encounter any difficulties accessing or logging in to the Annual Meeting, please call the technical support number displayed on the login page of the online virtual annual meeting platform.

Questions at the Virtual Annual Meeting

During the Annual Meeting, we will answer as many stockholder-submitted questions related to the proposals 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 that contain inappropriate or derogatory references which are not in good taste. If we receive substantially similar questions, we will group such questions together and provide a single response to avoid repetition.

Who Can Vote

Only holders of record of shares of our common stock at the close of business on September 22, 2025, the record date, will be entitled to notice of and to vote at the Annual Meeting. We have one class of common stock, and each holder of our common stock is entitled to one vote per share of common stock held as of the record date. At the close of business on the record date, 146,526,126 shares of our common stock were outstanding. Shares of treasury stock are not entitled to vote at the Annual Meeting.

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 17, 2025 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 [70](#i114f29450cd44bb4a6e3ecaf5327c40e_608) 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 17, 2025.

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.

**• Proposal 1:** Abstentions will be entirely excluded from the vote and will have no effect in determining the outcome of a director nominee's election.

**• Proposals 2, 3, and 4:** 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, except for abstentions on Proposal 3, which will have no effect, except to the extent that the failure to vote for a particular frequency period may result in another frequency period receiving a larger proportion of the votes cast.

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 4 (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 4 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 purposes of determining the presence of a quorum at the Annual Meeting and will be voted on Proposal 4 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. Because broker non-votes are not considered entitled to vote on these proposals, they 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.

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 will 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.

Attending the Annual Meeting

Anyone may attend the Annual Meeting online at **www.virtualshareholdermeeting.com/SNDK2025**, but you are only entitled to participate in the Annual Meeting, including asking questions and voting at the meeting, if you were a stockholder of record or a beneficial stockholder as of the close of business on September 22, 2025, the record date, or you hold a valid legal proxy for the Annual Meeting. To participate in the Annual Meeting, you will need the control number included on your Notice of Internet Availability of Proxy Materials, on your proxy card or on the instructions that accompanied your proxy materials.

Submission of Stockholder Proposals and Director Nominations

Proposals for Inclusion in Proxy Materials

For your proposal to be considered for inclusion in the proxy statement and form of proxy for our 2026 Annual Meeting, your written proposal must be received by our Secretary at our principal executive offices no later than June 9, 2026 and must comply with Rule 14a-8 of the Exchange Act regarding the inclusion of stockholder proposals in company-sponsored proxy materials. If we change the date of the 2026 Annual Meeting by more than 30 days from the anniversary 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 2026 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 2026 Annual Meeting or wish to present a proposal at the 2026 Annual Meeting but do not intend for such proposal to be included in the proxy statement for such meeting, our Bylaws require that 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 21, 2026 (the 120th day prior to the first anniversary of the Annual Meeting) and no later than the close of business on August 20, 2026 (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 2026 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 2026 Annual Meeting and no later than the close of business on the later of 90 days prior to the date of the 2026 Annual Meeting or the 10th day following the day on which public announcement of the date of the 2026 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 2026 Annual Meeting.

Written notice of any stockholder proposals not intended to be included in the proxy statement or nominations for director candidates that do not meet the notice requirements set forth above and further described in Section 2.11 of our Bylaws will be disregarded and not be acted upon at the 2026 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 10, 2026 (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 9, 2026 (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 2026 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 2026 Annual Meeting and no later than the close of business on the later of 120 days prior to the date of the 2026 Annual Meeting or the 10th day following the day on which public announcement of the date of the 2026 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.

Availability of Annual Report

Our 2025 Annual Report has been posted on our corporate website at **investor.sandisk.com** and on the Internet at **www.proxyvote.com**. For stockholders receiving a Notice of Internet Availability of Proxy Materials, the Notice will contain instructions on how to request a printed copy of our 2025 Annual Report. For stockholders receiving a printed copy of this Proxy Statement, a copy of our 2025 Annual Report also will be included. In addition, we will provide, without charge, a copy of our 2025 Annual Report (including the financial statements but excluding the exhibits thereto) upon the written request of any stockholder or beneficial owner of our common stock. Requests should be directed to our Secretary at our principal executive offices:

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 an alternative for measures prepared in accordance with GAAP and may be different from non-GAAP measures used by other companies. 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. 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, 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 the second half of fiscal 2025. In accordance with the pre-established terms of the STI, this non-GAAP performance measure excluded certain 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 measure, non-GAAP operating income or loss, excludes 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 measure primarily consist of stock-based compensation expense; business separation costs; employee termination and other; recoveries of contamination-related charges; strategic review; goodwill impairment; gain on business divestiture; and other adjustments.

The following tables present reconciliations of our GAAP operating loss to our non-GAAP operating income/ (loss) and our GAAP diluted income/(loss) per common share to our non-GAAP diluted income/(loss) per common share:

Explanations of Adjustments to Non-GAAP Measures

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

<u>Stock-based compensation expense.</u> 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 our control, we believe excluding stock-based compensation expense enhances the ability of management and investors to understand and assess the underlying performance of our business over time and compare it against our peers, a majority of whom also exclude stock-based compensation expense from their non-GAAP results.

<u>Business separation cost.</u> On October 30, 2023, WDC announced that its board of directors authorized management to pursue a plan to separate us into an independent public company. The separation received final approval by the WDC Board of Directors and was completed on February 21, 2025. Prior to February 21, 2025, we were wholly-owned by WDC. As a result of the plan, we incurred separation and transition costs through the completion of the separation of the companies. The separation and transition costs are recorded within Business separation costs in the Condensed Consolidated Statements of Operations. We believe these charges do not reflect our operating results and that they are not indicative of the underlying results of our business.

<u>Employee termination and other.</u> From time-to-time, in order to realign our operations with anticipated market demand, we may terminate employees and/or restructure our operations. From time-to-time, we may also incur charges from the impairment of long-lived assets. In addition, we may record credits related to gains upon sale of property due to restructuring or reversals of charges recorded in prior periods, as well as taking actions to reduce the amount of capital invested in facilities, including the sale-leaseback of facilities. These charges or credits are inconsistent in amount and frequency, and we believe they are not indicative of the underlying performance of our business.

<u>Recoveries of contamination-related charges.</u> In February 2022, a contamination of certain materials used in our manufacturing process occurred and affected production operations at the flash-based memory manufacturing facilities in Yokkaichi and Kitakami, Japan, which are operated through our joint business ventures with Kioxia. The contamination resulted in scrapped inventory, rework costs, decontamination and other expenses needed to restore the facilities to normal capacity. During the second quarter of fiscal year 2024, we received insurance recoveries for losses from contamination-related charges. The charges and recoveries are inconsistent in amount and frequency, and we believe they are not part of the ongoing production operation of our business.

<u>Strategic review.</u> We incurred expenses associated with our review of potential strategic alternatives aimed at further optimizing the long-term value for stockholders. We believe these charges do not reflect our operating results and that they are not indicative of the underlying performance of our business.

<u>Goodwill impairment</u>. After the completion of the separation, in the third quarter of fiscal 2025, we identified potential impairment indicators related to the trading price of our common stock and resulting market capitalization that warranted a quantitative impairment analysis of long-lived assets and goodwill. Management performed a quantitative impairment analysis and determined that the carrying value of the reporting unit exceeded its fair value, resulting in the recognition of a $1.8 billion impairment charge for the three months ended March 28, 2025. We believe this charge does not reflect our operating results and is not indicative of the underlying performance of our business.

<u>Gain on business divestiture</u>. In connection with our strategic decision to outsource the manufacturing of certain components and assemblies, on September 28, 2024, we completed the sale of 80% of our equity interest in one of our manufacturing subsidiaries. The transaction resulted in a discrete gain, which we believe is not indicative of the underlying performance of our ongoing business operations.

<u>Other adjustments.</u> From time-to-time, we sell or impair investments or other assets which are not considered necessary to our business operations, or incur other charges or gains that we believe are not a part of the ongoing operation of our business. The resulting expense or benefit is inconsistent in amount and frequency.
