Preliminary Prospectus dated May 1, 2025

PROSPECTUS

Up to 28,827,787 Shares

Sandisk Corporation

Common Stock

The selling stockholder identified in this prospectus may offer, from time to time, up to 28,827,787 shares of our common stock. We will not receive any of the proceeds from the sale of shares of our common stock by the selling stockholder. All of the shares registered by this prospectus are currently held by Western Digital Corporation (“WDC”). WDC does not own any other common stock or equity interests in us.

Our common stock is listed on the Nasdaq Stock Market LLC (“Nasdaq”) under the symbol “SNDK.” On April 30, 2025, the closing price of our common stock as reported on the Nasdaq was $32.11 per share.

In reviewing this prospectus, you should carefully consider the matters described under the caption “Risk Factors” beginning on page 13.

At the time the selling stockholder offers shares registered by this prospectus, we will provide a prospectus supplement that will contain specific information about the terms of the offering and that may add to or update the information in this prospectus. You should read this prospectus and the applicable prospectus supplement carefully before you invest.

WDC intends to dispose of the 28,827,787 shares of our common stock registered hereby through one or more exchanges of our common stock for WDC debt, unless it selects another method of distribution. WDC expects that any such debt-for-equity exchange would be effected to satisfy outstanding indebtedness under that certain Amended and Restated Loan Agreement, dated as of January 7, 2022, among WDC, JPMorgan Chase Bank, N.A., as administrative agent, and the lenders party thereto (as amended, the “Credit Agreement”), which governs WDC’s $2.51 billion Term Loan A-3 and revolving credit facility maturing in January 2027. In any such debt-for-equity exchange, WDC intends to deliver such shares to one or more affiliates of one or more third party lenders under the Credit Agreement, each of which we refer to, in such role, as a “debt-for-equity exchange party.” In connection therewith, WDC and such debt-for-equity exchange party will enter into an exchange agreement with respect to such shares. The debt-for-equity exchange party, and not WDC or us, will receive the proceeds from the sale of the shares in any such offering. However, as a result of exchanging the shares of our common stock with the debt-for-equity exchange party prior to any offering, WDC may be deemed to be a selling stockholder in such offering solely for U.S. federal securities law purposes. We refer to any such exchange between WDC and the debt-for-equity exchange parties as the “debt-for-equity exchange.” In the event WDC consummates a debt-for-equity exchange, the debt-for-equity exchange will occur on the settlement date of the applicable offering immediately prior to, and its consummation will be a condition to, the settlement of the selling stockholder’s sale of the shares to the underwriters in such offering. As a result, the consummation of such debt-for-equity exchange will also ultimately be a condition to the settlement of the underwriters’ sale of the shares to prospective investors in such offering. Alternatively, if market and general economic conditions do not support such exchanges, WDC may transfer such shares to holders of WDC common stock as dividends or in exchange for outstanding shares of WDC common stock.

The selling stockholder may offer the shares in amounts, at prices and on terms determined by market conditions at the time of the offering. The selling stockholder may sell shares through agents it selects or through underwriters and dealers it selects. The selling stockholder also may sell shares directly to investors.

If the selling stockholder uses agents, underwriters or dealers to sell the shares, we will name them and describe their compensation in a prospectus supplement.

Neither the U.S. Securities and Exchange Commission nor any state securities commission has approved or disapproved these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The date of this prospectus is     , 2025.

Industry

We operate in the data storage industry. The ability to access, store and share data from anywhere on any device is increasingly important to our customers and end users. From the intelligent edge to the cloud, data storage is a fundamental component underpinning the global technology architecture. Our strengths in innovation and cost leadership, diversified flash product portfolio and broad routes to market provide a foundation upon which we are solidifying our position as an essential building block of the digital economy. There is tremendous market opportunity flowing from the rapid global adoption of the technology architecture built with cloud infrastructure tied to intelligent endpoints all connected by high-performance networks. The value and urgency of data storage at every point across this architecture have never been clearer.

The increase in computing complexity and advancements in artificial intelligence, along with growth in cloud computing applications, connected mobile devices and Internet-connected products and edge devices is driving unabated growth in the volume of digital content to be stored and used. We believe our expertise and innovation in flash technology enable us to bring powerful solutions to a broader range of applications. We continuously monitor the full array of flash-based storage technologies, including reviewing these technologies with our customers, to ensure we are appropriately resourced to meet our customers’ storage needs.

Flash Technology

Flash products provide non-volatile data storage based on flash technology. We develop and manufacture solid state storage products for a variety of applications including enterprise or cloud storage, client storage, automotive, mobile devices and removable memory devices. Over time, we have successfully developed and commercialized successive generations of 2- and 3-dimensional flash technology with increased numbers of storage bits per cell in an increasingly smaller form factor, further driving cost reductions. We devote significant research and development resources to the development of highly reliable, high-performance, cost-effective flash-based technology and are continually pursuing developments in next-generation flash-based technology capacities. We are leveraging our expertise, resources and strategic investments in non-volatile memories to explore a wide spectrum of persistent memory and storage class memory technologies. We have also initiated, defined and developed standards to meet new market needs and to promote wide acceptance of flash storage standards through interoperability and ease of use.

Our Data Solutions

Our broad portfolio of technology and products addresses multiple end markets of “Cloud,” “Client” and “Consumer” and are comprised of the SanDisk® brand. Certain of our products will also be sold for a limited transitional period under the Western Digital®, WD® and other brands under license from WDC.

Operations

Our flash consists of flash-based memory, controllers and firmware and other components. Substantially all of our flash-based memory is obtained from our joint ventures with Kioxia, which provide us with leading-edge, high-quality and low-cost flash memory wafers. While substantially all of our flash memory supply utilized for our products is purchased from these ventures, from time to time, we also purchase flash memory from other flash manufacturers. Controllers are primarily designed in-house and manufactured by third-party foundries or acquired from third-party suppliers. Our assembly and test operations comprise in-house assembly and test facilities located in Penang, Malaysia and other contract manufacturers, and the assembly and test facility owned and operated by the venture established with JCET Management Co., Ltd. in Shanghai, China. We believe the use of our in-house assembly and test facilities and manufacturing partners provides flexibility and gives us access to increased production capacity.

We and Kioxia currently operate three business ventures, Flash Partners Ltd., Flash Alliance Ltd. and Flash Forward Ltd. (collectively, “Flash Ventures”), across seven flash-based manufacturing facilities in Japan, six of which are located in Yokkaichi, Japan and one of which is located in Kitakami, Japan. Flash Ventures will begin flash-based manufacturing operations at an eighth facility in Japan in calendar year 2025. Through Flash Ventures, we and Kioxia collaborate in the development and manufacture of flash-based memory wafers using semiconductor manufacturing equipment owned or leased by each of the Flash Ventures entities. We co-develop flash technologies (including process technology and memory design) with Kioxia for Flash Ventures’ use. We and Kioxia jointly own these co-developed flash technologies. We and Kioxia also contribute to the collaboration and license to each other technologies that are independently developed and owned by each of us and are reasonably necessary to our joint development or manufacture of flash-based memory. We hold a 49.9% ownership position in each of the Flash Ventures entities. We jointly control with Kioxia the operations of Flash Ventures, and we believe our participation in Flash Ventures helps us reduce product costs, increases our ability to control to the quality of our products and speeds delivery of our products to our customers.

Kioxia owns the facilities and provides wafer manufacturing services to Flash Ventures at cost using manufacturing equipment owned or leased by Flash Ventures and process technologies co-owned or contributed by us and Kioxia. Flash Ventures accounts for approximately 80% of the total manufacturing capacity in the facilities owned by Kioxia. We and Kioxia are entitled to purchase a share of Flash Ventures’ output, which generally equals 50% each. The price for which we and Kioxia pay Flash Ventures for flash memory wafers is cost plus a small markup. We are obligated to pay for variable costs incurred in producing our share of Flash Ventures’ flash-based memory wafer supply, based on a rolling forecast. In addition, we are obligated to pay for half of Flash Ventures’ fixed costs regardless of the output we choose to purchase.

While Flash Ventures is operating, we and Kioxia are restricted from working with third parties to manufacture flash-based memory or from fabricating flash-based memory beyond the capacity specified in our agreements with Kioxia. In addition, we may not manufacture flash-based memory ourselves except to the extent that we acquire the manufacturing capacity of a Flash Ventures entity as a result of such entity’s dissolution or termination of its joint venture agreements or upon our acquisition of all the ownership interests in such entity.

The agreements governing the operations of the Flash Ventures entities also set out a framework for any investment by the joint venture partners in flash manufacturing capacity. We have jointly invested, and intend to continue to jointly invest, with Kioxia in the manufacturing equipment needed to support Flash Ventures’ flash manufacturing operations. In addition, we are obligated to fund 49.9% to 50.0% of capital investments that a Flash Ventures entity decided to make to the extent that the Flash Ventures entity’s operating cash flow is insufficient to fund these investments.

Each Flash Ventures entity operates for a set amount of time as agreed between us and Kioxia. Since the start of Flash Ventures, we and Kioxia have extended the term for all three of the Flash Ventures entities. Absent further

4

##### Table of Contents

extensions as mutually agreed between us and Kioxia, Flash Partners Ltd. and Flash Alliance Ltd. are currently set to expire on December 31, 2029, and Flash Forward Ltd. is currently set to expire on December 31, 2034. Each Flash Ventures entity’s joint venture agreements may also earlier terminate upon the occurrence of certain specified events, including earlier dissolution by agreement of the parties or an event of default or bankruptcy. Upon the expiration of a Flash Ventures entity’s joint venture agreements, whenever that may occur, the applicable Flash Ventures entity will commence a wind-up process and be dissolved. Net proceeds from the dissolution will be distributed in kind or cash to us and Kioxia on a pro rata basis based on our respective ownership positions. The applicable Flash Venture entity will continue to operate during the period of winding up.

On January 24, 2025, the Company and WDC entered into an equity transfer agreement (the “Equity Transfer Agreement”) to transfer WDC’s entire equity interest in Unisplendour Corporation Limited and Unissoft (Wuxi) Group Co. Ltd. (“Unis”), referred to as the “Unis Venture,” to the Company. The Unis Venture is 49% owned by the Company and 51% owned by Unis. The Unis Venture markets and sells the Company’s products in China and develops data storage systems for the Chinese market.

Prior to the execution of the Equity Transfer Agreement, the Unis Venture was not historically managed as a component of the Company and as such, the related equity method investment was not reflected within our Condensed Consolidated Financial Statements. After the execution of the Equity Transfer Agreement, the Company accounts for its investment in the Unis Venture under the equity method of accounting. The Company’s 49% interest in the earnings of the Unis Venture will be recognized one quarter in arrears from the date the Unis Venture was transferred to the Company and will be reported in Other expense, net in the Condensed Consolidated Statements of Operations.

In addition, in September 2024, SanDisk China Limited, our wholly owned subsidiary, established a venture with JCET Management Co., Ltd. (“JCET”), referred to as the “SDSS Venture,” regarding the ownership and operations of our assembly and test facility in Shanghai, China. The SDSS Venture is 20% owned by Sandisk and 80% owned by JCET.

| • |  | Our level of debt may negatively impact our liquidity, restrict our operations and ability to respond to business opportunities and increase our vulnerability to adverse economic and industry conditions;

| • |  | We are subject to laws, rules and regulations relating to the collection, use, sharing and security of data, including personal data, and our failure to comply with these laws, rules and regulations could subject us to proceedings by governmental entities or others and cause us to incur penalties, significant legal liability or loss of customers, loss of revenue and reputational harm;

| • |  | We and certain of our officers may at times be involved in litigation, investigations and governmental proceedings, which may be costly, may divert the efforts of our key personnel and could result in adverse court rulings, fines or penalties, which could materially harm our business;

| • |  | The compromise, damage or interruption of our technology infrastructure, systems or products by cyber incidents, data security breaches, other security problems, design defects or system failures could have a material negative impact on our business;

| • |  | The nature of our industry and its reliance on intellectual property and other proprietary information subjects us and our suppliers, customers and partners to the risk of significant litigation;

| • |  | Our reliance on intellectual property and other proprietary information subjects us to the risk that these key components of our business could be copied by competitors; and

| • |  | Future material impairments in the value of our goodwill, intangible assets and other long-lived assets would negatively affect our operating results.

Risks Related to the Spin-Off

| • |  | We may not achieve some or all of the expected benefits of the spin-off, and the spin-off may adversely impact our business;

| • |  | Our historical and pro forma financial information is not necessarily representative of the results that we would have achieved as a separate, publicly traded company and therefore may not be a reliable indicator of our future results;

| • |  | In connection with our spin-off from WDC, WDC has agreed to indemnify us for certain liabilities. However, there can be no assurance that the indemnity will be sufficient to protect us against the full amount of such liabilities, or that WDC’s ability to satisfy its indemnification obligation will not be impaired in the future;

##### Table of Contents

| • |  | In connection with our spin-off from WDC, we have agreed to assume, and indemnify WDC for, certain liabilities. If we are required to make payments pursuant to these indemnities to WDC, we would need to meet those obligations and our financial results could be adversely impacted;

| • |  | If the distribution of shares of Sandisk, together with certain related transactions, does not continue to qualify as a reorganization within the meaning of sections 368(a)(1)(D), 361 and 355 of the Internal Revenue Code of 1986 (the “Code”) that is generally tax-free for U.S. federal income tax purposes (the “Intended Tax Treatment”), Sandisk, WDC and WDC stockholders that received shares of Sandisk in the distribution or receive shares in a clean-up distribution (as defined below) could be subject to significant U.S. federal income tax liability and, in certain circumstances, Sandisk could be required to indemnify WDC for material taxes pursuant to indemnification obligations under the tax matters agreement;

| • |  | To preserve the Intended Tax Treatment, under the tax matters agreement that Sandisk has entered into with WDC, Sandisk is restricted from taking certain actions after the distribution that could adversely impact the Intended Tax Treatment; and

| • |  | The spin-off and related internal restructuring transactions may expose us to potential liabilities arising out of state and federal fraudulent conveyance laws and legal dividend requirements.

Risks Related to Our Common Stock

| • |  | Our stock price may fluctuate significantly, which may make it difficult for you to resell the common stock when you want or at prices you find attractive;

| • |  | The selling stockholder owns 28,827,787 shares of our common stock. We are registering on a registration statement on Form S-1, of which this prospectus forms a part, such shares under the terms of a stockholder’s and registration rights agreement between us and the selling stockholder. The sale of such shares in one or more offerings may cause our stock price to decline;

| • |  | Provisions of Delaware law, our certificate of incorporation and our bylaws may prevent or delay an acquisition of our company, which could decrease the market price of our common stock;

| • |  | The price of WDC’s common stock historically has been volatile, and the price of our common stock may continue to be volatile. This volatility may affect the price at which you could sell your common stock, and the sale of substantial amounts of our common stock could adversely affect the price of our common stock; and

| • |  | Tax matters may materially affect our financial position and results of operations.

These and other risks relating to our business, our industry, the spin-off and our common stock are discussed in greater detail under the section of this prospectus entitled “Risk Factors.” You should read and consider all of these risks carefully.

Summary of the Separation and Distribution

On October 30, 2023, WDC announced its intention to separate its Flash Business from its hard disk drive business (the “HDD Business”). WDC determined to implement this separation through the spin-off of WDC’s Flash Business to its stockholders. Sandisk was formed to hold the Flash Business.

On January 25, 2025, the WDC Board of Directors approved the distribution of 80.1% of Sandisk’s issued and outstanding shares of common stock held by WDC to WDC stockholders on the basis of one share of our common stock for every three shares of WDC common stock held as of 1:00 p.m. Pacific time on February 12, 2025, the record date for the distribution (the “Record Date”), subject to certain conditions.

##### Table of Contents

On February 21, 2025, the distribution was effected and the separation became effective as of 11:59 p.m. Pacific time. Following the separation, we hold the assets and liabilities related to the Flash Business, subject to certain limited exceptions. After the separation, WDC continues to hold its HDD Business. To effect the separation, WDC undertook a series of internal restructuring transactions to separate the assets, liabilities and certain legal entities of WDC associated with the Flash Business to us, in exchange for a cash payment of approximately $1.5 billion by us to WDC with a portion of the net proceeds of a term loan facility described below under “Financing Transactions.” In conjunction with the separation, 116,035,464 shares of our common stock were distributed to WDC stockholders, as described below. Additionally, WDC retained 28,827,787 shares of our common stock representing its 19.9% retained interest. “Regular-way” trading of our common stock began with the opening of the Nasdaq on February 24, 2025, under the ticker symbol “SNDK.” Our common stock has a par value of $0.01 per share.

Following the distribution, our stockholders (other than WDC) own directly 80.1% of the outstanding shares of our common stock and WDC retained 19.9% of the outstanding shares of our common stock. WDC (the selling stockholder named herein) intends to dispose of all of our common stock that it retains through one or more subsequent exchanges of our common stock for WDC debt held by WDC creditors and/or through distributions of our common stock to WDC stockholders as dividends or in exchange for outstanding shares of WDC common stock, in each case during the 12-month period following the distribution (any such distribution, a “clean-up distribution”).

We are registering the shares retained by WDC on a registration statement on Form S-1, of which this prospectus forms a part, under the terms of a stockholder’s and registration rights agreement between us and the selling stockholder.

Financing Transactions

On February 21, 2025, we entered into a Loan Agreement (the “Loan Agreement”) by and among Sandisk, the lenders party thereto, JPMorgan Chase Bank, N.A., as administrative agent and collateral agent and the other parties party thereto. The Loan Agreement comprises a term loan B facility in the principal amount of $2.0 billion (the “Term Loan Facility”) and a revolving credit facility in the principal amount of $1.5 billion (the “Revolving Credit Facility” and together with the Term Loan Facility, the “Facilities”). On February 21, 2025, we borrowed $2.0 billion under the Term Loan Facility. There were no amounts outstanding as of April 30, 2025 under the Revolving Credit Facility. For additional information regarding the Loan Agreements and the Facilities, see the section entitled “Description of Material Indebtedness.”

Sandisk’s Post-Separation Relationship with WDC

On February 21, 2025, we entered into a separation and distribution agreement with WDC. In connection with the separation, we also entered into various other agreements to effect the separation and provide a framework for our relationship with WDC after the separation, including a transition services agreement, a tax matters agreement, an employee matters agreement, an intellectual property cross-license agreement, a transitional trademark license agreement and a stockholder’s and registration rights agreement with respect to WDC’s continuing ownership of Sandisk’s common stock. These agreements provide for the allocation between us and WDC of WDC’s assets, employees, liabilities and obligations (including investments, property and employee benefits and tax-related assets and liabilities) attributable to periods prior to, at and after our separation from WDC and govern certain relationships between us and WDC after the separation. For additional information regarding the separation and distribution agreement and other transaction agreements, see the sections entitled “Risk Factors—Risks Related to the Spin-off” and “Certain Relationships and Related Party Transactions.” For additional information regarding the internal reorganization, see the section entitled “The Separation and Distribution—Internal Reorganization.”

RISK FACTORS

The risks and uncertainties described below could materially and adversely impact our business, financial condition, results of operations, could cause actual results to differ materially from our expectations and projections, and could cause the market value of our stock to decline. You should consider these risk factors when evaluating us and our common stock and when reading the rest of this prospectus, including the sections entitled “Business” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our financial statements and related notes included elsewhere in this document. These risk factors may not include all of the important factors that could affect our business or our industry or that could cause our future financial results to differ materially from historic or expected results or cause the market price of our common stock to fluctuate or decline. Additional risks and uncertainties not currently known to us or that we currently believe are immaterial also may impair our business, including our results of operations, liquidity and financial condition.

Risks Related to Our Business

OPERATIONAL RISKS

Adverse global or regional conditions could harm our business.

A large portion of our revenue is derived from our international operations, and substantially all of our products are produced overseas. As a result, our business depends significantly on global and regional conditions. Adverse changes in global or regional economic conditions, including, but not limited to, volatility in the financial markets, tighter credit, recession, inflation, rising interest rates, slower growth in certain geographic regions, political uncertainty, geopolitical tensions or conflicts, trade war, other macroeconomic factors, changes to social conditions and regulations, could significantly harm demand for our products, increase credit and collectability risks, result in revenue reductions, reduce profitability as a result of underutilization of our assets, cause us to change our business practices, increase manufacturing and operating costs or result in impairment charges or other expenses.

Our revenue growth is significantly dependent on the growth of international markets, and we may face challenges in international sales markets. We are subject to risks associated with our global manufacturing operations and global sales efforts, as well as risks associated with our utilization of contract manufacturers, including:

| • |  | obtaining governmental approvals and compliance with evolving foreign regulations;

| • |  | the need to comply with regulations on international business, including the Foreign Corrupt Practices Act, the United Kingdom Bribery Act 2010, the anti-bribery laws of other countries and rules regarding conflict minerals;

| • |  | exchange, currency and tax controls and reallocations;

| • |  | weaker protection of intellectual property rights;

| • |  | policies and financial incentives by governments in China, the United States and countries in Europe and Asia designed to reduce dependence on foreign semiconductor manufacturing capabilities;

| • |  | trade restrictions, such as export controls, export bans, import restrictions, embargoes, sanctions, license and certification requirements (including semiconductor, encryption and other technology), tariffs and complex customs regulations; and

| • |  | difficulties in managing international operations, including appropriate internal controls.

For example, the United States has recently announced changes to U.S. trade policy, including increasing tariffs on imports, in some cases significantly. These tariffs have the potential to raise the cost of our products sold in

13

##### Table of Contents

the U.S. or adversely affect demand for our products in the U.S. Additionally, we cannot predict responsive or future trade policy and regulations in the U.S. and other countries, the terms of any trade arrangements that may be negotiated between the U.S. and other countries, the scope, amount, or duration of tariffs that may be imposed by any country, or the impact of these factors on our business. Each of these factors could increase the costs of our products and the materials and components used in our products, increase the prices of our products, and adversely affect demand for our products. Uncertainty surrounding international trade policy and regulations could also have an adverse effect on consumer confidence and spending.

As a result of these risks, our business could be harmed.

We are dependent on a limited number of qualified suppliers who provide critical services, materials or components, and a disruption in our supply chain or other inability to source our supply requirements, or an increase in the costs of materials or components, could negatively affect our business.

We depend on an external supply base for technologies, software (including firmware), controllers, dynamic random-access memory, components, equipment and materials for use in our product design and manufacturing. We also depend on suppliers for a portion of our wafer testing, chip assembly, product assembly and product testing, and on service suppliers for providing technical support for our products. In addition, we use logistics partners to manage our worldwide just-in-time hubs and distribution centers and to meet our freight needs. Many of the components and much of the equipment we acquire must be specifically designed for use in our products or for developing and manufacturing our products, and are only available from a limited number of suppliers, some of whom are our sole-source suppliers. We therefore depend on these suppliers to meet our business needs including dedicating adequate engineering resources to develop components that can be successfully integrated into our products.

Our suppliers have in the past been, and may in the future be, unable or unwilling to meet our requirements, including as a result of events outside of their control such as trade restrictions (including tariffs, quotas and embargoes), geopolitical conflicts, public health emergencies or natural disasters. If we are unable to purchase sufficient quantities from our current suppliers or qualify and engage additional suppliers, or if we cannot purchase materials at a reasonable price, we may not be able to meet demand for our products. Trade restrictions, including tariffs, quotas and embargoes, demand from other high-volume industries for materials or components used in our products, disruptions in supplier relationships or shortages in other components and materials used in our customers’ products could result in increased costs to us or decreased demand for our products, which could negatively impact our business. Delays, shortages or cost increases experienced by our suppliers in developing or sourcing materials and components for use in our products or incompatibility or quality issues relating to our products, could also harm our business.

We do not have long-term contracts with some of our existing suppliers, nor do we always have guaranteed manufacturing capacity with our suppliers, so we cannot guarantee that they will devote sufficient resources or capacity to manufacturing our products. Any significant problems that occur at our suppliers could lead to product shortages or quality assurance problems. When we do have contractual commitments with suppliers in an effort to stabilize the supply of our components, those commitments may require us to buy a substantial number of components or make significant cash advances to the supplier and may not result in a satisfactory supply of our components. We may cancel or defer outstanding purchase commitments with certain suppliers due to changes in actual and forecasted demand, which may result in fees, penalties and other associated charges. Such cancellations or deferments may also negatively impact our relationships with certain suppliers or lead to a decline in the financial performance of certain suppliers, each of which could result in even more limited availability of components needed for our products.

In addition, our supply base has experienced industry consolidation. Our suppliers may be acquired by our competitors, decide to exit the industry or redirect their investments and increase costs to us. In addition, some of our suppliers have experienced a decline in financial performance, including as a result of canceled or deferred

14

##### Table of Contents

purchase commitments. Where we rely on a limited number of suppliers or a single supplier, the risk of supplier loss due to industry consolidation or a decline in financial performance is increased. Some of our suppliers may also be competitors in other areas of our or their business, which could lead to difficulties in price negotiations or meeting our supply requirements.

Our operations, and those of certain of our suppliers and customers, are subject to substantial risk of damage or disruption.

We conduct our operations at large, high-volume, purpose-built facilities in Japan, Malaysia and throughout Asia. The facilities of many of our customers, our suppliers and our customers’ suppliers are also concentrated in certain geographic locations throughout Asia and elsewhere. If a fire (including a climate change-related fire), flood, earthquake, tsunami or other natural disaster, condition or event such as a power outage, contamination event, terrorist attack, cybersecurity incident, physical security breach, political instability, civil unrest, localized labor unrest or other employment issues, or a health epidemic negatively affects any of these facilities, it would significantly affect our ability to manufacture or sell our products and source components and would harm our business. Possible impacts include work and equipment stoppages and damage to or closure of our facilities, or those of our suppliers or customers, for an indefinite period of time. Climate change has in the past and is expected to continue to increase the incidence and severity of certain natural disasters, including wildfires and adverse weather events. In addition, the geographic concentration of our manufacturing sites could exacerbate the negative impacts resulting from any of these problems.

We may incur losses beyond the limits of, or outside the scope of, the coverage of our insurance policies. There can be no assurance that in the future we will be able to maintain existing insurance coverage or that premiums will not increase substantially. Due to market availability, pricing or other reasons, we may elect not to purchase insurance coverage or to purchase only limited coverage. We maintain limited insurance coverage and, in some cases, no coverage at all, for natural disasters and damage to our facilities, as these types of insurance are sometimes not available or available only at a prohibitive cost. Climate change may reduce the availability or increase the cost of certain types of insurance by contributing to an increase in the incidence and severity of certain natural disasters. We depend upon Kioxia to obtain and maintain sufficient property, business interruption and other insurance for Flash Ventures. If Kioxia fails to do so, we could suffer significant unreimbursable losses, and such failure could also cause Flash Ventures to breach various financing covenants.

Public health crises have had, and could in the future have, a negative effect on our business.

Public health crises may negatively impact our workforce and operations, as well as those of our strategic partners, customers, suppliers and logistics providers. Impacts of public health crises may include, without limitation, closures of our manufacturing facilities; under-absorbed overhead; increased logistics, component and other costs; decreased demand for our products; and manufacturing challenges.

The effects of public health crises are uncertain and difficult to predict, but may also include:

| • |  | Disruptions to our supply chain, our operations or those of our strategic partners, customers or suppliers caused by employees or others contracting infectious diseases, or by governmental orders to contain the spread of infectious disease, such as travel restrictions, quarantines, shelter in place orders, trade controls and business shutdowns;

| • |  | Deterioration of worldwide credit markets that may limit our ability or increase our cost to obtain external financing to fund our operations and capital expenditures and result in a higher rate of losses on our accounts receivables due to customer credit defaults;

| • |  | Extreme volatility in financial markets, which may harm our ability to access the financial markets on acceptable terms;

15

##### Table of Contents

| • |  | Increased data security and technology risk as some employees work from home, including possible outages to systems and technologies critical to remote work and increased data privacy risk with cybercriminals attempting to take advantage of the disruption; and

| • |  | Reduced productivity or other disruptions of our operations if workers in Flash Ventures’ factories or our other worksites are exposed to or spread infectious diseases to other employees.

The degree to which any public health crises ultimately impact our business will depend on many factors beyond our control, which are highly uncertain and cannot be predicted at this time.

The loss of our key management, staff and skilled employees, the inability to hire and develop new employees or decisions to realign our business could negatively impact our business prospects.

Our success depends upon the continued contributions of our talent. Changes in our key management team, including the allocation of key employees between us and WDC in connection with the separation, may result in loss of continuity, loss of accumulated knowledge, departure of other key employees, disruptions to our operations and inefficiency during transitional periods. Global competition for skilled employees in the technology industry is intense, and our business success is increasingly dependent on our ability to attract, develop and retain top talent, implement succession plans for key management and staff and replace aging skilled employees. We have put retention arrangements in place for key employees to address the uncertainty about our business separation. We may suffer further attrition following payment of these retention arrangements. Changes in immigration policies may also impair our ability to recruit and hire technical and professional talent.

Our ability to hire and retain employees also depends on our ability to build and maintain a diverse and inclusive workplace culture and to fund competitive compensation and benefits, each of which contribute to being viewed as an employer of choice. Additionally, because a substantial portion of our key employees’ compensation is linked to the performance of our business, we may be at a competitive disadvantage for hiring and retaining talent when our operating results are negatively impacted. If we are unable to hire and retain key talent, our operating results would likely be harmed.

We are subject to risks related to product defects, which could result in product recalls or epidemic failures and could subject us to warranty claims in excess of our warranty provisions or which are greater than anticipated, litigation or indemnification claims.

We warrant the majority of our products for periods of one to five years. We test our products in our manufacturing facilities through a variety of means. However, our testing may fail to reveal defects in our products that may not become apparent until after the products have been sold into the market. In addition, our products may be used in a manner that is not intended or anticipated by us, resulting in potential liability. Accordingly, there is a risk that product defects will occur, including as a result of third-party components or applications that we incorporate in our products, which could require a product recall. Product recalls can be expensive to implement. As part of a product recall, we may be required or choose to replace the defective product. Moreover, there is a risk that product defects may trigger an epidemic failure clause in a customer agreement. If an epidemic failure occurs, we may be required to replace or refund the value of the defective product and to cover certain other costs associated with the consequences of the epidemic failure. In addition, product defects, product recalls or epidemic failures may cause damage to our reputation or customer relationships, lost revenue, indemnification for a recall of our customers’ products, warranty claims, litigation or loss of market share with our customers, including our original equipment manufacturer and original design manufacturer customers. Our business liability insurance may be inadequate or future coverage may be unavailable on acceptable terms, which could negatively impact our operating results and financial condition.

Our standard warranties contain limits on damages and exclusions of liability for consequential damages and for misuse, improper installation, alteration, accident or mishandling while in the possession of someone other than

16

##### Table of Contents

us. We record an accrual for estimated warranty costs at the time revenue is recognized. We may incur additional expenses if our warranty provisions do not reflect the actual cost of resolving issues related to defects in our products, whether as a result of a product recall, epidemic failure or otherwise. If these additional expenses are significant, they could harm our business.

The compromise, damage or interruption of our technology infrastructure, systems or products by cyber incidents, data security breaches, other security problems, design defects or system failures could have a material negative impact on our business.

We experience cyber incidents of varying degrees on our technology infrastructure and systems and, as a result, unauthorized parties may obtain access to our computer systems and networks, including cloud-based platforms.

For example, an unauthorized third party gained access to a number of WDC’s systems in March 2023, which caused disruption to parts of WDC’s business operations and resulted in various investigation, recovery and remediation expenses. In addition, the technology infrastructure and systems of some of our suppliers, vendors, service providers, cloud solution providers and partners have in the past experienced, and may in the future experience, such incidents. Cyber incidents can be caused by ransomware, computer denial-of-service attacks, worms and other malicious software programs or other attacks, including the covert introduction of malware to computers and networks, and the use of techniques or processes that change frequently, may be disguised or difficult to detect, or are designed to remain dormant until a triggering event, and may continue undetected for an extended period of time. Cyber incidents may result from, social engineering or impersonation of authorized users, and may also result from efforts to discover and exploit any design flaws, bugs, security vulnerabilities or security weaknesses, intentional or unintentional acts by employees or other insiders with access privileges, intentional acts of vandalism or fraud by third parties and sabotage. In some instances, efforts to correct vulnerabilities or prevent incidents may reduce the functionality or performance of our computer systems and networks, which could negatively impact our business. We believe malicious cyber acts are increasing in number and that cyber threat actors are increasingly organized and well-financed or supported by state actors, and are developing increasingly sophisticated systems and means to not only infiltrate systems, but also to evade detection or to obscure their activities. Geopolitical tensions or conflicts may create heightened risk of cyber incidents.

Our products are also targets for malicious cyber acts, including those products utilized in cloud-based environments. While some of our products contain encryption or security algorithms to protect third-party content or user-generated data stored on our products, these products could still be hacked or the encryption schemes could be compromised, breached or circumvented by motivated and sophisticated attackers, which could harm our business by exposing us to litigation and indemnification claims and hurting our reputation. If efforts to breach our infrastructure, systems or products are successful or we are unable to protect against these risks, we could suffer interruptions, delays or cessation of operations of our systems, and loss or misuse of proprietary or confidential information, IP or sensitive or personal information. For example, as a result of a network security incident in March 2023, an unauthorized party obtained a copy of a WDC database used for WDC’s online store that contained some personal information of our online store customers. Compromises of our infrastructure, systems or products could also cause our customers and other affected third parties to suffer loss or misuse of proprietary or confidential information, IP or sensitive or personal information, and could harm our relationships with customers and other third parties and subject us to liability. As a result of actual or perceived breaches, we may experience additional costs, notification requirements, civil and administrative fines and penalties, indemnification claims, litigation or damage to our brand and reputation. All of these consequences could harm our reputation and our business and materially and negatively impact our operating results and financial condition.

BUSINESS AND STRATEGIC RISKS

We rely substantially on strategic relationships with various partners, including Kioxia, which subjects us to risks and uncertainties that could harm our business.

We have entered into and expect to continue to enter into strategic relationships with various partners for product development, manufacturing, sales growth and the supply of technologies, components, equipment and materials for use in our product design and manufacturing, including our business ventures with Kioxia. We depend on Flash Ventures for the development and manufacture of flash-based memory. Our strategic relationships, including Flash Ventures, are subject to various risks that could harm the value of our investments, our revenue and costs, our future rate of spending, our technology plans and our future growth opportunities.

The terms of our agreements with Kioxia with respect to the Flash Ventures requires that substantially all of our flash-based memory be obtained from Flash Ventures, which limits our ability to respond to market demand and supply changes and makes our financial results particularly susceptible to variations from our forecasts and expectations. For example, we are contractually obligated to pay for 50% of the fixed costs of Flash Ventures regardless of whether we order any flash-based memory, and our orders placed with Flash Ventures on a rolling basis are binding. As a result, a failure to accurately forecast supply and demand could cause us to over-invest or under-invest in inventory, technology transitions or the expansion of Flash Ventures’ capacity. Over-investment by us or our competitors can result in excess supply and lead to significant decreases in our product prices, significant excess, obsolete inventory or inventory write-downs or underutilization charges, and the potential impairment of our investments in Flash Ventures. For example, in 2023, WDC incurred $296 million in charges for unabsorbed manufacturing overhead costs as a result of reduced utilization of its manufacturing capacity and $108 million in charges to write down our inventory as a result of decreases in market pricing. These charges were attributable to a significant imbalance of supply and demand and WDC’s actions taken in response thereto. On the other hand, if we under-invest in Flash Ventures, or otherwise grow or transition Flash Ventures’ capacity too slowly, we may not have enough supply of flash-based memory, or the right type of flash-based memory, to meet demand on a timely and cost effective basis, and we may lose opportunities for revenue, gross margin and market share as a result. If our supply is limited, we might make strategic decisions with respect to the allocation of our supply among our products and customers, which could result in less favorable gross margins or damage customer relationships. In addition, while Flash Ventures is operating, our agreements with Kioxia preclude us from working with third parties to manufacture flash-based memory or from fabricating flash-based memory beyond the capacity specified in the agreements, or from manufacturing flash-based memory ourselves except to the extent that we acquire any manufacturing capacity of a Flash Ventures entity as a result of that entity’s dissolution, termination of its joint venture agreements or acquisition by us. This could also impair our ability to consolidate with other industry participants who manufacture flash-based memory.

Our control over the operations of our business ventures may be limited, and our interests could diverge from our strategic partners’ interests regarding ongoing and future activities. For example, each Flash Ventures entity operates for a defined period of time agreed upon between the joint venture partners. Absent further extensions as mutually agreed between us and Kioxia, Flash Partners Ltd. and Flash Alliance Ltd. are currently set to expire on December 31, 2029, and Flash Forward Ltd. is currently set to expire on December 31, 2034. Each Flash Ventures entity’s joint venture agreements may also earlier terminate upon the occurrence of certain specified events, including earlier dissolution by agreement of the parties or an event of default or bankruptcy. Upon the expiration of a Flash Ventures entity’s joint venture agreements, whenever that may occur, the applicable Flash Ventures entity will commence a wind-up process and be dissolved. Net proceeds from the dissolution will be distributed in kind or cash to us and Kioxia on a pro rata basis based on our respective ownership positions. The applicable Flash Venture entity will continue to operate during the period of winding up. Although we and Kioxia have agreed to extend the operating period for each Flash Ventures entity since the start of Flash Ventures, there is a risk that we and Kioxia will be unable to agree on a further extension of one or more of the Flash Ventures entities. Additionally, under the Flash Ventures agreements, we cannot unilaterally direct most of Flash Ventures’ activities, and we have limited ability to source or fabricate flash outside of Flash Ventures. Flash Ventures requires significant investments by both Kioxia and us for technology transitions and capacity

18

##### Table of Contents

expansions, and our business could be harmed if our technology roadmap and investment plans are not sufficiently aligned with Kioxia’s. Lack of alignment with Kioxia with respect to Flash Ventures could negatively impact our ability to react quickly to changes in the market, or to stay at the forefront of technological advancement. Misalignment could arise due to changes in Kioxia’s strategic priorities, management, ownership or access to capital, which have changed in recent years and could continue to change. Kioxia’s stakeholders may include, or have included in the past, competitors, customers, a private equity firm, government entities or public stockholders. Kioxia’s management changes, ownership and capital structure could lead to delays in decision-making, disputes or changes in strategic direction that could negatively impact the strategic partnership, and therefore us. There may exist conflicts of interest between Kioxia’s stakeholders and Flash Ventures or us with respect to, among other things, protecting and growing Flash Ventures’ business, intellectual property and competitively sensitive confidential information.

Together with Kioxia, we fund a portion of the investments required for Flash Ventures through lease financings. Continued availability of lease financings for Flash Ventures is not guaranteed and could be limited by several factors, including investor capacity and risk allocation policies, our or Kioxia’s financial performance and changes to our or Kioxia’s business, ownership or corporate structure. To the extent that lease financings are not accessible on favorable terms or at all, more cash would be required to fund investments.

Our strategic relationships are subject to additional risks that could harm our business, including, but not limited to, the following:

| • |  | failure by our strategic partners to comply with applicable laws or employ effective internal controls;

| • |  | difficulties and delays in product and technology development at, ramping production at and transferring technology to, our strategic partners;

| • |  | declining financial performance of our strategic partners, including failure by our strategic partners to timely fund capital investments with us or otherwise meet their commitments, including paying amounts owed to us or third parties when due;

| • |  | we may lose the rights to, or ability to independently manufacture, certain technology or products being developed or manufactured by strategic partners, including if any of them is acquired by another company, files for bankruptcy or experiences financial or other losses;

| • |  | a bankruptcy event involving a strategic partner could result in structural changes to or termination of the strategic partnership; and

| • |  | changes in tax or regulatory requirements may necessitate changes to the agreements governing our strategic partnerships.

We participate in a highly competitive industry that is subject to declining average selling prices, volatile demand, rapid technological change and industry consolidation, as well as lengthy product qualifications, all of which can negatively impact our business.

Demand for our devices, software and solutions, which we refer to in this “Risk Factors” section as our “products,” depends in large part on the demand for systems manufactured by our customers and on storage upgrades to existing systems. The demand for systems has been volatile in the past and often has had an exaggerated effect on the demand for our products in any given period. Demand for and prices of our products are influenced by, among other factors, actual and projected data growth, the balance between supply and demand in the storage market, including the effects of new fab capacity, macroeconomic factors, business conditions, technology transitions and other actions taken by us or our competitors. The storage market has recently experienced, and may continue to experience, periods of excess capacity leading to liquidation of excess inventories, inventory write-downs, significant reductions in average selling prices and negative impacts on our revenue and gross margins, and volatile product life cycles that harm our ability to recover the cost of product development.

19

##### Table of Contents

Further, our average selling prices and gross margins tend to decline when there is a shift in the mix of product sales to lower priced products. We have faced declining gross margins relating to the Flash Business in the past, and may face potential gross margin pressures in the future, resulting from our average selling prices declining more rapidly than our cost of revenue. Rapid technological changes often reduce the volume and profitability of sales of existing products and increase the risk of inventory obsolescence and write-downs. Finally, the data storage industry has experienced consolidation over the past several years, which could enhance the resources and lower the cost structure of some competitors. These factors could result in a substantial decrease in our market share and harm our business.

As we compete in new product areas, the overall complexity of our business may increase and may result in increases in research and development expenses and substantial investments in manufacturing capability, technology enhancements and go-to-market capability. We must also qualify our products with customers through potentially lengthy testing processes with uncertain results. Some of our competitors offer products that we do not offer, which may allow them to win sales from us, and some of our customers may be developing storage solutions internally, which may reduce their demand for our products. We expect that competition will continue to be intense, and our competitors may be able to gain a product offering or cost structure advantage over us, which would harm our business. Further, our competitors may utilize pricing strategies, including offering products at prices at or below cost, that we may be unable to competitively match. We may also have difficulty effectively competing with manufacturers benefiting from governmental investments and may be subject to increased complexity and reduced efficiency in our supply chain as a result of governmental efforts to promote domestic semiconductor industries in various jurisdictions.

If we do not properly manage technology transitions and product development and introduction, our competitiveness and operating results may be negatively affected.

The markets for our products continuously undergo technology transitions that may impact our product roadmaps and that we must anticipate in order to adapt our existing products or develop new products effectively. If we fail to adapt to or implement new technologies or develop new products desired by our customers quickly and cost-effectively, or if technology transitions negatively impact our existing product roadmaps, our business may be harmed.

In addition, the success of our technology transitions and product development depends on a number of other factors, including:

| • |  | research and development expenses and results;

| • |  | difficulties faced in manufacturing ramp;

| • |  | market acceptance/qualification;

| • |  | effective management of inventory levels in line with anticipated product demand;

| • |  | the vertical integration of some of our products, which may result in more capital expenditures and greater fixed costs than if we were not vertically integrated;

| • |  | our ability to cost effectively respond to customer requests for new products or features (including requests for more efficient and efficiently produced products with reduced environmental impacts) and software associated with our products;

| • |  | our ability to increase our software development capability; and

| • |  | the effectiveness of our go-to-market capability in selling new products.

Moving to new technologies and products may require us to align to, and build, a new supply base. Our success in new product areas may depend on our ability to enter into favorable supply agreements. In addition, if our customers choose to delay transition to new technologies, if demand for the products that we develop is lower

20

##### Table of Contents

than expected or if the supporting technologies to implement these new technologies are not available, we may be unable to achieve the cost structure required to support our profit objectives or may be unable to grow or maintain our market position.

Additionally, new technologies could impact demand for our products in unforeseen or unexpected ways and new products could substitute for our current products and make them obsolete, each of which would harm our business. We also develop products to meet certain industry and technical standards, which may change and cause us to incur substantial costs as we adapt to new standards or invest in different manufacturing processes to remain competitive.

We experience sales seasonality and cyclicality, which could cause our operating results to fluctuate. In addition, accurately forecasting demand has become more difficult, which could harm our business.

Sales of many of our products tend to be seasonal and subject to supply-demand cycles. Changes in seasonal and cyclical supply and demand patterns have made it, and could continue to make it, more difficult for us to forecast demand. Changes in the product or channel mix of our business may also impact seasonal and cyclical patterns. For example, we often ship a high percentage of our total quarterly sales in the third month of the quarter, which makes it difficult for us to forecast our financial results before the end of each quarter. As a result of the above or other factors, our forecast of financial results for a given quarter may differ materially from our actual financial results.

The variety and volume of products we manufacture are based in part on accurately forecasting market and customer demand for our products. Accurately forecasting demand has become increasingly difficult for us, our customers and our suppliers due to volatility in global economic conditions, end market dynamics and industry consolidation, resulting in less availability of historical market data for certain product segments. Further, for many of our original equipment manufacturer customers utilizing just-in-time inventory, we do not generally require firm order commitments and instead receive a periodic forecast of requirements, which may prove to be inaccurate. In addition, because our products are designed to be largely interchangeable with competitors’ products, our demand forecasts may be impacted significantly by the strategic actions of our competitors. As forecasting demand becomes more difficult, the risk that our forecasts are not in line with demand increases. This has caused, and may in the future cause, our forecasts to exceed actual market demand, resulting in periods of product oversupply, excess inventory, underutilization of manufacturing capacity and price decreases, which has impacted and could further impact our sales, average selling prices and gross margin or require us to incur additional inventory write-downs or additional charges for unabsorbed manufacturing overhead, thereby negatively affecting our operating results and our financial condition. For example, in 2023, WDC incurred $296 million in charges for unabsorbed manufacturing overhead costs as a result of reduced utilization of its manufacturing capacity and $108 million in charges to write down its inventory as a result of decreases in market pricing. These charges were attributable to a significant imbalance of supply and demand and our actions taken in response thereto. If market demand increases significantly beyond our forecasts or beyond our ability to add manufacturing capacity, then we may not be able to satisfy customer product needs, possibly resulting in a loss of market share if our competitors are able to meet customer demands. In addition, some of our components have long lead-times, requiring us to place orders several months in advance of anticipated demand. Such long lead-times increase the risk of excess inventory, potentially resulting in inventory write-downs or loss of sales in the event our forecasts vary substantially from actual demand.

Failure to successfully execute on strategic initiatives including acquisitions, divestitures or cost saving measures may negatively impact our future results.

We may make acquisitions and divestitures and engage in cost saving measures. In order to successfully execute on strategic initiatives, we must successfully complete attractive transactions, some of which may be large and complex, and manage post-closing issues such as integration of the acquired company or employees and integration of processes and systems. We may not be able to identify or complete appealing acquisition or

21

##### Table of Contents

investment opportunities given the intense competition for these transactions. Even if we identify and complete suitable corporate transactions, we may not be able to successfully address any integration challenges in a timely manner, or at all. There may be difficulties with implementing new systems and processes or with integrating systems and processes of companies with complex operations, which may result in inconsistencies in standards, controls, procedures and policies and may increase the risk that our internal controls are found to be ineffective.

Failing to successfully integrate or realign our business to take advantage of efficiencies or reduce redundancies of an acquisition may result in not realizing all or any of the anticipated benefits of the acquisition. In addition, failing to achieve the financial model projections for an acquisition or changes in technology development and related roadmaps following an acquisition may result in the incurrence of impairment charges (including goodwill impairments or other asset write-downs) and other expenses, both of which could negatively impact our results of operations or financial condition. Acquisitions and investments may also result in the issuance of equity securities that may be dilutive to our stockholders as well as earn-out or other contingent consideration payments and the issuance of additional indebtedness that would put additional pressure on liquidity. Furthermore, we may agree to provide continuing service obligations or enter into other agreements in order to obtain certain regulatory approvals of our corporate transactions, and failure to satisfy these additional obligations could result in our failing to obtain regulatory approvals or the imposition of additional obligations on us, any of which could negatively affect our business. In addition, new legislation or additional regulations may affect or impair our ability to invest with or in certain other countries or require us to obtain regulatory approvals to do so, including investments in joint ventures, minority investments and outbound technology transfers to certain countries.

Cost saving measures, restructurings and divestitures may result in workforce reduction and consolidation of our manufacturing or other facilities. As a result of these actions, we may experience a loss of continuity, loss of accumulated knowledge, disruptions to our operations and inefficiency during transitional periods. These actions could also impact employee retention. In addition, we cannot be sure that these actions will be as successful in reducing our overall expenses as we expect, that additional costs will not offset any such reductions or consolidations or that we do not forgo future business opportunities as a result of these actions.

Acquisitions and alliance activities inherently involve other risks as well. Additional risks we may encounter include those associated with:

| • |  | disruption to our business and the continued successful execution of our company strategy, goals and responsibilities;

| • |  | increased capital and research and development expenses and resource allocation;

| • |  | assimilation and integration of different business operations, corporate cultures, personnel, infrastructures and technologies or solutions acquired or licensed, while maintaining quality, and designing and implementing appropriate risk management measures;

| • |  | the incurrence of significant transaction fees and costs;

| • |  | the potential for unknown liabilities within the acquired or combined business that we may not become aware of until after the completion of the acquisition; and

| • |  | the possibility of conflict with joint venture or alliance partners regarding strategic direction, prioritization of objectives and goals, governance matters or operations.

Loss of revenue from a key customer, or consolidation among our customer base, could harm our operating results.

For 2024, 2023 and 2022, 41%, 47% and 47%, respectively, of our total revenue came from sales to our top ten customers. These customers have a variety of suppliers to choose from and therefore can make substantial demands on us, including demands on product pricing, contractual terms and the environmental impact and

22

##### Table of Contents

attributes of our products, often resulting in the allocation of risk or increased costs to us as the supplier. Our ability to maintain strong relationships with our principal customers is essential to our future performance. We may experience events such as the loss of a key customer, prohibition or restriction of sales to a key customer by law, regulation or other government action, reductions in sales to or orders by a key customer, customer requirements to reduce our prices before we are able to reduce costs or the acquisition of a key customer by one of our competitors. These events may impact our operating results and financial condition. Further, government authorities may implement laws or regulations or take other actions that could result in significant changes to the business or operating models of our customers. Such changes could negatively impact our operating results.

Additionally, if there is consolidation among our customer base, our customers may be able to command increased leverage in negotiating prices and other terms of sale, which could negatively impact our profitability. Consolidation among our customer base may also lead to reduced demand for our products, increased customer pressure on our prices, replacement of our products by the combined entity with those of our competitors and cancellations of orders, each of which could harm our operating results.

Also, the storage ecosystem is constantly evolving, and our traditional customer base is changing. Fewer companies now hold greater market share for certain applications and services, such as cloud storage and computing platforms, mobile, social media, shopping and streaming media. As a result, the competitive landscape is changing, giving these companies increased leverage in negotiating prices and other terms of sale, which could negatively impact our profitability. In addition, the changes in our evolving customer base create new selling and distribution patterns to which we must adapt. To remain competitive, we must respond to these changes by ensuring we have proper scale in this evolving market, as well as offer products that meet the technological requirements of this customer base at competitive pricing points. To the extent we are not successful in adequately responding to these changes, our operating results and financial condition could be harmed.

Sales in the distribution channel and to the retail market are important to our business, and if we fail to respond to demand changes within these markets, or maintain and grow our applicable market share, our business could suffer.

Our distribution customers typically sell to small computer manufacturers, dealers, systems integrators and other resellers. We face significant competition in this channel as a result of limited product qualification programs and a significant focus on price and availability of product. As a result of the shift to mobile devices, more computing devices are being delivered to the market as complete systems, which could weaken the distribution market. If we fail to respond to changes in demand in the distribution market, our business could suffer. Additionally, if the distribution market weakens as a result of technology transitions or a significant change in consumer buying preference, or if we experience significant price declines due to demand changes in the distribution channel, our operating results would be negatively impacted. Negative changes in the creditworthiness or the ability to access credit, or the bankruptcy or shutdown of any of our significant retail or distribution partners would harm our revenue and our ability to collect outstanding receivable balances.

A significant portion of our sales is also made through retailers. Our success in the retail market depends in large part on our ability to maintain our brand image and corporate reputation and to expand into and gain market acceptance of our products in multiple retail market channels. Particularly in the retail market, negative publicity, whether or not justified, or allegations of product or service quality issues, even if false or unfounded, could damage our reputation and cause our customers to choose products offered by our competitors. Further, changes to the retail environment, such as store closures caused by macroeconomic conditions or changing customer preferences, may reduce the demand for our products. If customers no longer maintain a preference for our product brands or if our retailers are not successful in selling our products, our operating results may be negatively impacted.

FINANCIAL RISKS

Our level of debt may negatively impact our liquidity, restrict our operations and ability to respond to business opportunities and increase our vulnerability to adverse economic and industry conditions.

In connection with the separation, we incurred and utilized debt financing in our capital structure, and in the future, we may incur additional debt. The amount of debt may be substantial and may be on terms less favorable to us than those historically provided to WDC. Our level of debt could have significant consequences, which may include, but are not limited to, the following:

| • |  | limiting our ability to obtain additional financing for working capital, capital expenditures, acquisitions, capital contributions to Flash Ventures or other general corporate purposes;

| • |  | requiring a substantial portion of our cash flows to be dedicated to debt service payments instead of other purposes;

| • |  | imposing financial and other restrictive covenants on our operations, including minimum liquidity and free cash flow requirements and limitations on our ability to (i) declare or pay dividends or repurchase shares of our common stock; (ii) purchase assets, make investments, complete acquisitions, consolidate or merge with or into, or sell all or substantially all of our assets to, another person; (iii) enter into sale/leaseback transactions or certain transactions with affiliates; (iv) incur additional indebtedness and (v) incur liens; and

| • |  | making us more vulnerable to economic downturns and limiting our ability to withstand competitive pressures or take advantage of new opportunities to grow our business.

Our ability to meet our debt service obligations, comply with our debt covenants and deleverage will depend on our cash flows and financial performance, which may be affected by financial, business, economic and other factors. The rate at which we are able to or choose to deleverage is uncertain. Failure to meet our debt service obligations or comply with our debt covenants could result in an event of default under the applicable indebtedness. We may be unable to cure, or obtain a waiver of, an event of default or otherwise amend our debt agreements to prevent an event of default thereunder on terms acceptable to us or at all. In that event, the debt holders could accelerate the related debt, which may result in the cross-acceleration or cross-default of other debt, leases or other obligations. If we do not have sufficient funds available to repay indebtedness when due, whether at maturity or by acceleration, we may be required to sell important strategic assets, refinance such debt, incur additional debt or issue common stock or other equity securities, which we may not be able to do on terms acceptable to us, in amounts sufficient to meet our needs or at all. Our inability to service our debt obligations or refinance our debt could harm our business. Further, if we are unable to repay, refinance or restructure any of our indebtedness that is secured, the holder of such debt could proceed against the collateral securing the indebtedness. Refinancing our indebtedness may also require us to expense previous debt issuance costs or to incur new debt issuance costs.

Our financing arrangements include bank debt containing a variable interest rate component based on our corporate credit ratings, and a decline in our ratings could result in increased interest rates and debt service obligations. In addition, our ratings will impact the cost and availability of future borrowings and, accordingly, our cost of capital. Our ratings will reflect the opinions of the ratings agencies as to our financial strength, operating performance and ability to meet our debt obligations. There can be no assurance that we will achieve a particular rating or maintain a particular rating in the future.

We also guarantee a significant amount of lease obligations of Flash Ventures owed to third parties. Flash Ventures sells to and leases back a portion of its equipment from a consortium of financial institutions. Most of the lease obligations are guaranteed 50% by us and 50% by Kioxia. Some of the lease obligations are guaranteed in full by us. The leases are subject to customary covenants and cancellation events that relate to Flash Ventures and each of the guarantors. If a cancellation event were to occur, Flash Ventures would be required to negotiate a resolution with the other parties to the lease transactions to avoid cancellation and acceleration of the lease

obligations. Such resolution could include, among other things, supplementary security to be supplied by us, increased interest rates or waiver fees. If a resolution is not reached, we may be required to pay all of the outstanding lease obligations covered by our guarantees, which would significantly reduce our cash position and may force us to seek additional financing, which may not be available on terms acceptable to us, if at all.

We may from time to time seek to further refinance our indebtedness by issuing additional shares of common stock or other securities that are convertible into common stock or grant the holder the right to purchase common stock, each of which may dilute our existing stockholders, reduce the value of our common stock, or both.

Fluctuations in currency exchange rates as a result of our international operations may negatively affect our operating results.

Because we manufacture and sell our products abroad, our revenue, cost of revenue, margins, operating costs and cash flows are impacted by fluctuations in foreign currency exchange rates. If the U.S. dollar exhibits sustained weakness against most foreign currencies, the U.S. dollar equivalents of unhedged manufacturing costs could increase because a significant portion of our production costs are foreign-currency denominated. Conversely, there would not be an offsetting impact to revenues since revenues are substantially U.S. dollar denominated. Additionally, we negotiate and procure some of our component requirements in U.S. dollars from non-U.S. based vendors. If the U.S. dollar weakens against other foreign currencies, some of our component suppliers may increase the price they charge for their components in order to maintain an equivalent profit margin. In addition, our purchases of flash-based memory from Flash Ventures and our investment in Flash Ventures are denominated in Japanese yen. If the Japanese yen appreciates against the U.S. dollar, our cost of purchasing flash-based memory wafers and the cost to us of future capital funding of Flash Ventures would increase. When such events occur, they have had, and may in the future have, a negative impact on our business.

Prices for our products are substantially U.S. dollar denominated, even when sold to customers that are located outside the U.S. Therefore, as a substantial portion of our sales are from countries outside the U.S., fluctuations in currency exchanges rates, most notably the strengthening of the U.S. dollar against other foreign currencies, contribute to variations in sales of products in impacted jurisdictions and could negatively impact demand and revenue growth. In addition, currency variations may adversely affect margins on sales of our products in countries outside the U.S.

We have historically attempted to manage the impact of foreign currency exchange rate changes by, among other things, entering into short-term foreign exchange contracts. The effectiveness of this hedging strategy is dependent on business, market and global economic conditions, and our approach to foreign currency exchange rate hedging is subject to change. Even when used for hedging purposes, foreign exchange contracts may not cover our full exposure and can be canceled by the counterparty if currency controls are put in place. Thus, this hedging strategy with respect to currency risks may not be successful and may actually harm our operating results. Further, the ability to enter into foreign exchange contracts with financial institutions is based upon our available credit from such institutions and compliance with covenants and other restrictions. Operating losses, third-party downgrades of our credit rating or instability in the worldwide financial markets could impact our ability to effectively manage our foreign currency exchange rate risk. Hedging also exposes us to the credit risk of our counterparty financial institutions.

Increases in our customers’ credit risk could result in credit losses and term extensions under existing contracts with customers with credit losses could result in an increase in our operating costs.

Some of our original equipment manufacturer customers have adopted a subcontractor model that requires us to contract directly with companies, such as original design manufacturers, that provide manufacturing and fulfillment services to our original equipment manufacturer customers. Because these subcontractors are generally not as well capitalized as our direct original equipment manufacturer customers, this subcontractor model exposes us to increased credit risks. Our agreements with our original equipment manufacturer customers

25

##### Table of Contents

may not permit us to increase our product prices to alleviate this increased credit risk. Additionally, as we attempt to expand our original equipment manufacturer and distribution channel sales into emerging economies, the customers with the most success in these regions may have relatively short operating histories, making it more difficult for us to accurately assess the associated credit risks. Our customers’ credit risk may also be exacerbated by an economic downturn or other adverse global or regional economic conditions. Any credit losses we may suffer as a result of these increased risks, or as a result of credit losses from any significant customer, especially in situations where there are term extensions under existing contracts with such customers, would increase our operating costs, which may negatively impact our operating results.

LEGAL AND COMPLIANCE RISKS

We are subject to laws, rules and regulations relating to the collection, use, sharing and security of data, including personal data, and our failure to comply with these laws, rules and regulations could subject us to proceedings by governmental entities or others and cause us to incur penalties, significant legal liability or loss of customers, loss of revenue and reputational harm.

We are subject to laws, rules and regulations relating to the collection, use, security and privacy of third-party data, including data that relates to or identifies an individual person. We are also subject to the terms of our privacy policies and obligations to third parties related to privacy, data protection and cybersecurity. In many cases, these requirements apply not only to third-party transactions, but also to transfers of information between us and our subsidiaries, and among us, our subsidiaries and other parties with which we have commercial relations. Our possession and use of third-party data, including personal data and employee data in conducting our business, subjects us to legal and regulatory burdens that require us to notify vendors, customers or employees or other parties with which we have commercial relations of a data security breach and to respond to regulatory inquiries and to enforcement proceedings. Laws and regulations relating to the collection, use, security and privacy of third-party data change over time and new laws and regulations become effective from time to time. We are subject to notice and privacy policy requirements, as well as obligations to respond to requests to know and access personal information, correct personal information, delete personal information and say no to the sale of personal information. Global privacy and data protection legislation, enforcement and policy activity in this area are rapidly expanding and evolving and may be inconsistent from jurisdiction to jurisdiction. We may also be subject to restrictions on cross-border data transfers and requirements for localized storage of data that could increase our compliance costs and risks and affect the ability of our global operations to coordinate activities and respond to customers. Compliance requirements or even our inadvertent failure to comply with applicable laws may cause us to incur substantial costs, subject us to proceedings by governmental entities or others, and cause us to incur penalties or other significant legal liability or lead us to change our business practices.

We are or may in the future be subject to state, federal and international legal and regulatory requirements, such as environmental, labor, health and safety, trade and public-company reporting and disclosure regulations, customers’ standards of corporate citizenship and industry and coalition standards, such as those established by the Responsible Business Alliance (“RBA”), and compliance with those regulations and requirements could cause an increase in our operating costs and failure to comply may harm our business.

We are subject to, and may become subject to additional, state, federal and international laws and regulations governing our environmental, labor, trade, health and safety practices and public-company reporting and disclosures requirements. These laws and regulations, particularly those applicable to our international operations, are or may be complex, extensive and subject to change. We will need to ensure that we and our suppliers, customers and partners timely comply with such laws and regulations, which may result in an increase in our operating costs. Legislation has been, and may in the future be, enacted in locations where we manufacture or sell our products, which could impair our ability to conduct business in certain jurisdictions or with certain customers and harm our operating results. In addition, climate change and financial reform legislation is a significant topic of discussion and has generated and may continue to generate federal, international or other

26

##### Table of Contents

regulatory responses in the near future, which could substantially increase the complexity of our public-company reporting and disclosure requirements and our compliance and operating costs. If we or our suppliers, customers or partners fail to timely comply with applicable legislation, certain customers may refuse to purchase our products or we may face increased operating costs as a result of taxes, fines or penalties, or legal liability and reputational damage, which could harm our business.

In connection with our compliance with environmental laws and regulations, as well as our compliance with industry and coalition environmental initiatives, such as those established by the RBA, the standards of business conduct required by some of our customers, and our commitment to sound corporate citizenship in all aspects of our business, we could incur substantial compliance and operating costs and be subject to disruptions to our operations and logistics. In addition, if we or our suppliers, customers or partners were found to be in violation of these laws or noncompliant with these initiatives or standards of conduct, we could be subject to governmental fines, liability to our customers and damage to our reputation and corporate brand, which could cause our financial condition and operating results to suffer.

Our aspirations, disclosures and actions related to environmental, social and governance matters expose us to risks that could adversely affect our reputation and performance.

There is a focus from investors, customers, associates, business partners and other stakeholders concerning environmental, social and governance matters, and we may announce initiatives and goals related to environmental, social and governance matters from time to time, including renewable energy and net zero emissions commitments. These statements reflect our current plans and aspirations and are not guarantees that we will be able to achieve them. Our ability to achieve any environmental, social and governance objective is subject to numerous risks, many of which are outside of our control, including the availability and cost of alternative energy sources; the evolving regulatory and reporting requirements affecting environmental, social and governance practices and disclosures; the locations and usage of our products and the implications on their greenhouse gas emissions; and the successful execution of our strategy. Our failure to accomplish or accurately track and report on these goals on a timely basis, or at all, and the potential added costs involved, could adversely affect our reputation; financial performance and growth; our ability to attract or retain talent; and our attractiveness as a business partner or supplier, and could expose us to increased litigation risk, as well as increased scrutiny from the investment community and enforcement authorities.

We and certain of our officers may at times be involved in litigation, investigations and governmental proceedings, which may be costly, may divert the efforts of our key personnel and could result in adverse court rulings, fines or penalties, which could materially harm our business.

From time to time, we may be involved in litigation, including antitrust and commercial matters, putative securities class action suits and other actions. We may be the plaintiff in some of these actions and the defendant in others. Some of the actions may seek injunctive relief, including injunctions against the sale of our products, and substantial monetary damages, which if granted or awarded, could materially harm our business. From time to time, we may also be the subject of inquiries, requests for information, investigations and actions by government and regulatory agencies regarding our business. Any such matters could result in material adverse consequences to our results of operations, financial condition or ability to conduct our business, including fines, penalties or restrictions on our business activities.

Litigation is subject to inherent risks and uncertainties that may cause actual results to differ materially from our expectations. In the event of an adverse outcome in any litigation, investigation or governmental proceeding, we could be required to pay substantial damages, fines or penalties and cease certain practices or activities, including the manufacture, use and sale of products. With or without merit, such matters may be complex, may extend for a protracted period of time, may be very expensive and the expense may be unpredictable. Litigation initiated by us could also result in counter-claims against us, which could increase the costs associated with the litigation and result in our payment of damages or other judgments against us. In addition, litigation, investigations or

27

##### Table of Contents

governmental proceedings and any related publicity may divert the efforts and attention of some of our key personnel, affect demand for our products and harm the market prices of our securities.

We may be obligated to indemnify our current or former directors or employees, or former directors or employees of companies that we have acquired, in connection with litigation, investigations or governmental proceedings. These liabilities could be substantial and may include, among other things: the costs of defending lawsuits against these individuals; the cost of defending shareholder derivative suits; the cost of governmental, law enforcement or regulatory investigations or proceedings; civil or criminal fines and penalties; legal and other expenses; and expenses associated with the remedial measures, if any, which may be imposed.

The nature of our industry and its reliance on intellectual property and other proprietary information subjects us and our suppliers, customers and partners to the risk of significant litigation.

The data storage industry has been characterized by significant litigation. This includes litigation relating to patent and other intellectual property rights, product liability claims and other types of litigation. We have historically been involved in frequent disputes regarding patent and other intellectual property rights, and we and our customers have in the past received, and we and our customers may in the future receive, communications from third parties asserting that certain of our products, processes or technologies infringe upon their patent rights, copyrights, trademark rights or other intellectual property rights. Even if we believe that such claims are without merit, they may be time-consuming and costly to defend against and may divert management’s attention and resources away from our business. We may also receive claims of potential infringement if we attempt to license intellectual property to others. Intellectual property risks increase when we enter into new markets where we have little or no intellectual property protection as a deterrent against litigation. The complexity of the technology involved and the uncertainty of intellectual property litigation increase the intellectual property risks we face. Litigation may be expensive, lengthy and disruptive to normal business operations. Moreover, the results of litigation are inherently uncertain and may result in adverse rulings or decisions. We may be subject to injunctions, enter into settlements or be subject to judgments that may harm our business.

If we incorporate third-party technology into our products or if claims or actions are asserted against us for alleged infringement of the intellectual property of others, we may be required to obtain a license or cross-license, modify our existing technology or design a new non-infringing technology. Such licenses or design modifications may be extremely costly. We evaluate notices of alleged patent infringement and notices of patents from patent holders that we receive from time to time. We may decide to settle a claim or action against us, which settlement could be costly. We may also be liable for past infringement. If there is an adverse ruling against us in an infringement lawsuit, an injunction could be issued barring production or sale of any infringing product. It could also result in a damage award equal to a reasonable royalty or lost profits or, if there is a finding of willful infringement, treble damages. Any of these results would increase our costs and harm our operating results. In addition, our suppliers, customers and partners are subject to similar risks of litigation, and a material, adverse ruling against a supplier, customer or partner could negatively impact our business.

Moreover, from time to time, we agree to indemnify certain of our suppliers and customers for alleged intellectual property infringement. The scope of such indemnity varies but may include indemnification for direct and consequential damages and expenses, including attorneys’ fees. We may be engaged in litigation as a result of these indemnification obligations. Third-party claims for patent infringement are excluded from coverage under our insurance policies. A future obligation to indemnify our customers or suppliers may harm our business.

Our reliance on intellectual property and other proprietary information subjects us to the risk that these key components of our business could be copied by competitors.

Our success depends, in significant part, on the proprietary nature of our technology, including non-patentable intellectual property such as our process technology. If we fail to protect our technology, intellectual property or contract rights, our customers and others may seek to use our technology and intellectual property without the

28

##### Table of Contents

payment of license fees and royalties, which could weaken our competitive position, reduce our operating results and increase the likelihood of costly litigation. We primarily rely on patent, copyright, trademark and trade secret laws, as well as non-disclosure agreements and other methods, to protect our proprietary technologies and processes. There can be no assurance that our existing patents will continue to be held valid, if challenged, or that they will have sufficient scope or strength to protect us. It is also possible that competitors or other unauthorized third parties may obtain, copy, use or disclose, illegally or otherwise, our proprietary technologies and processes, despite our efforts to protect our proprietary technologies and processes. If a competitor is able to reproduce or otherwise capitalize on our technology despite the safeguards we have in place, it may be difficult, expensive or impossible for us to obtain necessary legal protection. There are entities whom we believe may infringe our IP. Enforcement of our rights often requires litigation. If we bring a patent infringement action and are not successful, our competitors may be able to use similar technology to compete with us. Moreover, the defendant in such an action may successfully countersue us for infringement of their patents or assert a counterclaim that our patents are invalid or unenforceable. Also, the laws of some foreign countries may not protect our intellectual property to the same extent as do U.S. laws. In addition to patent protection of intellectual property rights, we consider elements of our product designs and processes to be proprietary and confidential. We rely upon employee, consultant and vendor non-disclosure agreements and contractual provisions and a system of internal safeguards to protect our proprietary information. However, we cannot be certain that these contracts and safeguards have not been and will not be breached, that we will be able to timely detect unauthorized use or transfer of our technology and intellectual property, that we will have adequate remedies for any breach, or that our trade secrets will not otherwise become known or be independently discovered by competitors. Any of our registered or unregistered intellectual property rights may be challenged or exploited by others in the industry, which could harm our operating results.

Maintaining and strengthening our brands are important to maintaining and expanding our business, as well as to our ability to enter into new markets for our technologies, products and services. The success of our brands depends in part on the positive image that consumers have of our brands. We believe the popularity of our brands makes them a target of counterfeiting or imitation, with third parties attempting to pass off counterfeit products as our products. Any occurrence of counterfeiting, imitation or confusion with our brands could negatively affect our reputation and impair the value of our brands, which in turn could negatively impact sales of our branded products, our share and our gross margin, as well as increase our administrative costs related to brand protection and counterfeit detection and prosecution. Additionally, our ability to prevent unauthorized uses of our brands and technologies would be negatively impacted if our trademark registrations were successfully challenged or overturned in the jurisdictions where we do business. We also have trademark applications pending in a number of jurisdictions that may not ultimately be granted, or if granted, may be challenged or invalidated, in which case we would be unable to prevent unauthorized use of our brands and logos in such jurisdictions. We have not filed trademark registrations in all jurisdictions where our brands or logos may be used.

Future material impairments in the value of our goodwill, intangible assets and other long-lived assets would negatively affect our operating results.

We regularly review our goodwill and property, plant and equipment for potential impairment. Goodwill and indefinite-lived intangible assets are subject to impairment reviews on an annual basis, or more frequently if events or changes in circumstances indicate that goodwill may be impaired. We use qualitative factors to determine whether goodwill is more-likely-than-not impaired and whether a quantitative test for impairment is considered necessary. If we conclude from the qualitative assessment that goodwill is more-likely-than-not-impaired, we are required to perform a quantitative analysis to determine the amount of impairment. Subsequent to the completion of the separation, we identified potential impairment indicators related to the trading price of our common stock and a resulting market capitalization that was below its December 27, 2024 net book value. In accordance with Accounting Standards Codification No. 350, Intangibles - Goodwill and Other, we initiated a quantitative analysis of potential impairment of goodwill and long-lived assets. That analysis is ongoing, and we believe it is more likely than not that we will record an impairment charge in the three months ended March 28, 2025. Further adverse changes to macroeconomic conditions or our estimates of

29

##### Table of Contents

the fair value of our reporting unit could impact the amount of any impairment charges or lead to additional impairment charges. Material impairment charges would negatively affect our results of operations.

Risks Related to the Spin-Off

We may not achieve some or all of the expected benefits of the spin-off, and the spin-off may adversely impact our business.

We may not realize any strategic, financial, operational or other benefits from the spin-off. We cannot predict with certainty if or when anticipated benefits will occur or the extent to which they will be achieved. Following the completion of the spin-off, our operational and financial profile has changed and may continue to change and we face new risks. We are now a smaller and less-diversified company compared to WDC prior to the spin-off, and may be more vulnerable to changing market conditions. While we believe that the spin-off has positioned each company to better unlock its full standalone long-term potential, we cannot assure you that we will be successful. Further, there can be no assurance that the combined value of our shares and the shares of WDC is or will be equal to or greater than what the value of our common stock would have been had the spin-off not occurred. We or WDC may offer products or engage in businesses that compete with the other company’s products or businesses. Under the separation and distribution agreement between WDC and us, WDC is subject to certain limited noncompetition obligations for a specified period of time after the separation but otherwise will not be restricted in its ability to compete with us.

We have incurred and expect to continue to incur ongoing material costs and expenses as a result of the spin-off.

We may incur costs and expenses greater than those we expected to incur as a result of the spin-off. These increased costs and expenses may arise from various factors, including financial reporting and costs associated with complying with federal securities laws (including compliance with the Sarbanes-Oxley Act). We have incurred and expect to continue to incur ongoing costs and dis-synergies in connection with, or as a result of, the separation and related restructuring transactions, including costs of operating as independent, publicly traded companies that the two businesses will no longer be able to share. We cannot assure you that these costs will not be material to our business.

If we are unable to satisfy the requirements of Section 404 of the Sarbanes-Oxley Act, or our internal control over financial reporting is not effective, the reliability of our financial statements may be questioned, and our stock price may suffer.

Section 404 of the Sarbanes-Oxley Act requires any company subject to the reporting requirements of the U.S. securities laws to do a comprehensive evaluation of its and its consolidated subsidiaries’ internal control over financial reporting. Neither we nor our independent registered public accounting firm is required to formally attest to the effectiveness of our internal control over financial reporting until the year following the first annual report required to be filed with the SEC. To comply with this statute, we are required to document and test our internal control procedures, our management is required to assess and issue a report concerning our internal control over financial reporting and our independent registered public accounting firm is required to issue an opinion on our internal control over financial reporting. The rules governing the standards that must be met for management to assess our internal control over financial reporting are complex and require significant documentation, testing and possible remediation to meet the detailed standards under the rules. During the course of our testing, our management may identify material weaknesses or deficiencies which may not be remedied in time to meet the deadline imposed by the Sarbanes-Oxley Act. If our management concludes that our internal control over financial reporting is not effective, or we identify material weaknesses in our internal controls, investor confidence in our financial results may weaken, and our stock price may suffer.

We were spun off from our former parent company, WDC, and our historical and pro forma financial information is not necessarily representative of the results that we would have achieved as a separate, publicly traded company and therefore may not be a reliable indicator of our future results.

30

##### Table of Contents

We were spun off from WDC, our former parent company, and have only operated as an independent, publicly traded company since February 21, 2025. The historical information about us in this prospectus refers to our business as part of pre-spin-off WDC. Our historical and pro forma financial information included in this prospectus is derived from the combined financial statements and accounting records of WDC. Accordingly, the historical and pro forma financial information included in this prospectus does not necessarily reflect the financial condition, results of operations or cash flows that we would have achieved as a separate, publicly traded company during the periods presented or those that we will achieve in the future primarily as a result of the factors described below:

| • |  | we may need to make significant investments to replicate or outsource certain systems, infrastructure and functional expertise in the future. These initiatives to develop our independent ability to operate will be costly to implement. We may not be able to operate our business as efficiently or at comparable costs, and our profitability may decline;

| • |  | how we finance our working capital or other cash requirements may differ from how we financed those requirements as part of pre-spin-off WDC. Our access to and cost of debt financing is different from the historical access to and cost of debt financing under pre-spin-off WDC. Differences in access to and cost of debt financing are likely to result in differences in interest rates charged to us on financings, the amounts of indebtedness, types of financing structures and debt markets that may be available to us, which may have an adverse effect on our business, financial condition, results of operations and cash flows; and

| • |  | in preparing our financial statements, pre-spin-off WDC made allocations of costs and corporate expenses deemed to be attributable to our business. However, these costs and expenses reflect the costs and expenses attributable to our business operated as part of a larger organization and do not necessarily reflect costs and expenses that would be incurred by us had we been operating independently. As a result, our historical financial information may not be a reliable indicator of future results.

For additional information about the past financial performance of our business and the basis of presentation of the historical combined financial statements and the unaudited pro forma combined financial statements of our business, see the sections of this prospectus entitled “Unaudited Pro Forma Condensed Combined Financial Information,” “Notes to Unaudited Pro Forma Condensed Combined Financial Information,” “Summary of Historical and Unaudited Pro Forma Condensed Combined Financial Data” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” as well as the combined financial statements and accompanying notes, included elsewhere in this prospectus.

WDC may fail to perform under various transaction agreements that were executed as part of the spin-off, or we may fail to have necessary systems and services in place when WDC is no longer obligated to provide services under the various agreements.

In connection with our spin-off, we entered into certain agreements with WDC, such as the separation and distribution agreement, a transition services agreement, a tax matters agreement, an employee matters agreement, a stockholder’s and registration rights agreement, a transitional trademark license agreement and an intellectual property cross-license agreement, as discussed in greater detail in the section of this prospectus entitled “Certain Relationships and Related Transactions—Material Agreements with WDC,” which provide for the performance by each company for the benefit of the other for a period of time after the spin-off. If WDC is unable to satisfy its obligations under these agreements, including its indemnification obligations in favor of us, we could incur operational difficulties or losses.

If we do not have in place our own systems and services, and do not have agreements with other providers of these services when the transitional or other agreements terminate, or if we do not implement the new systems or replace WDC’s services successfully, we may not be able to operate our business effectively, which could disrupt our business and have a material adverse effect on our business, financial condition and results of operations.

31

##### Table of Contents

These systems and services may also be more expensive to install, implement and operate, or less efficient than the systems and services WDC provides during the transition period.

In connection with our spin-off from WDC, WDC has agreed to indemnify us for certain liabilities. However, there can be no assurance that the indemnity will be sufficient to protect us against the full amount of such liabilities, or that WDC’s ability to satisfy its indemnification obligation will not be impaired in the future.

WDC has agreed to indemnify us for certain liabilities as discussed further in the section of this prospectus entitled “Certain Relationships and Related Transactions—Material Agreements with WDC.” However, third parties could also seek to hold us responsible for liabilities that WDC has agreed to retain, and there can be no assurance that the indemnity from WDC will be sufficient to protect us against the full amount of such liabilities, or that WDC will be able to fully satisfy its indemnification obligations. In addition, WDC’s insurers may attempt to deny coverage to us for liabilities associated with certain occurrences of indemnified liabilities prior to the spin-off.

In connection with our spin-off from WDC, we have agreed to assume, and indemnify WDC for, certain liabilities. If we are required to make payments pursuant to these indemnities to WDC, we would need to meet those obligations and our financial results could be adversely impacted.

We have agreed to assume, and indemnify WDC for, certain liabilities as discussed further in the section of this prospectus entitled “Certain Relationships and Related Transactions—Material Agreements with WDC.” Payments pursuant to these indemnities may be significant and could adversely impact our business, financial condition, results of operations and cash flows, particularly indemnities relating to our actions that could impact the tax-free nature of the distribution.

If the distribution of our shares, together with certain related transactions, does not continue to qualify for the Intended Tax Treatment, Sandisk, WDC and WDC stockholders could be subject to significant U.S. federal income tax liabilities and, in certain circumstances, we could be required to indemnify WDC for material taxes pursuant to indemnification obligations under the tax matters agreement.

As a condition to the completion of the distribution, WDC received an opinion of counsel (the “Tax Opinion”) that, among other things, the distribution, together with certain related transactions, qualifies for the Intended Tax Treatment. The Tax Opinion was based on and relies on certain facts, assumptions, representations and undertakings from WDC and us, including those regarding the past and future conduct of the companies’ respective businesses and other matters. Nevertheless, an opinion of counsel neither binds the Internal Revenue Service (the “IRS”) nor precludes the IRS or the courts from adopting a contrary position. Therefore, notwithstanding the Tax Opinion, the IRS could determine that the distribution or any such related transaction is taxable if it determines that any of these facts, assumptions, representations or undertakings are not correct or have been violated, or that the distribution should be taxable for other reasons, including if the IRS were to disagree with the conclusions in the Tax Opinion.

If the distribution or certain related transactions failed to qualify for the Intended Tax Treatment, in general, for U.S. federal income tax purposes, WDC would recognize taxable gain as if it had sold the shares of our stock in a taxable sale for their fair market value and WDC stockholders that received shares of our stock in the distribution or receive shares of our stock in a clean-up distribution would be subject to tax as if they had received a taxable distribution equal to the fair market value of such shares.

In addition, WDC and Sandisk could incur significant U.S. federal income tax obligations, whether under applicable law or under the tax matters agreement that we entered into with WDC. For a discussion of the tax matters agreement, see “Certain Relationships and Related Party Transactions—Material Agreements with WDC—Tax Matters Agreement.”

##### Table of Contents

To preserve the tax-free treatment to WDC and its stockholders of the distribution and certain related transactions, under the tax matters agreement that we entered into with WDC, we are restricted from taking certain actions after the distribution that could adversely impact the intended U.S. federal income tax treatment of the distribution and such related transactions.

To preserve the tax-free treatment to WDC and its stockholders of the distribution and certain related transactions, under the tax matters agreement that we entered into with WDC, we are restricted from taking certain actions after the distribution that could adversely impact the intended U.S. federal income tax treatment of the distribution, together with certain related transactions. Failure to adhere to any such restrictions, including in certain circumstances that may be outside of our control, could result in tax being imposed on WDC for which we could bear responsibility and for which we could be obligated to indemnify WDC. In addition, even if we are not responsible for tax liabilities of WDC under the tax matters agreement, we nonetheless could potentially be liable under applicable tax law for such liabilities if WDC were to fail to pay such taxes.

The terms of the tax matters agreement, furthermore, restrict us from taking certain actions, particularly for the two years following the spin-off, including (among other things) the ability to freely issue stock, to merge or agree to merge with a third party, to be acquired or agree to be acquired by certain parties and to raise additional equity capital. Such restrictions could impair our ability to implement strategic initiatives. Also, any indemnity obligation to WDC might discourage, delay or prevent a change of control that we or our stockholders may otherwise consider favorable. These restrictions may limit our ability to enter into certain strategic transactions or other transactions that we may believe to be in the best interests of our stockholders or that might increase the value of our business. In addition, under the tax matters agreement, we are required to indemnify WDC against certain tax liabilities as a result of the acquisition of our stock or assets, even if we did not participate in or otherwise facilitate the acquisition. For a discussion of the tax matters agreement, see the section of this prospectus entitled “Certain Relationships and Related Transactions—Material Agreements with WDC—Tax Matters Agreement.”

The spin-off and related internal restructuring transactions may expose us to potential liabilities arising out of state and federal fraudulent conveyance laws and legal dividend requirements.

The spin-off could be challenged under various state and federal fraudulent conveyance laws. Fraudulent conveyances or transfers are generally defined to include (a) transfers made or obligations incurred with the actual intent to hinder, delay or defraud current or future creditors or (b) transfers made or obligations incurred for less than reasonably equivalent value when the debtor was insolvent, or that rendered the debtor insolvent, inadequately capitalized or unable to pay its debts as they become due. A creditor or an entity acting on behalf of a creditor (including, without limitation, a trustee or debtor-in-possession in a bankruptcy by us or WDC or any of our or its respective subsidiaries) may bring a lawsuit alleging that the spin-off or any of the related transactions constituted a fraudulent conveyance. If a court accepts these allegations, it could impose a number of remedies, including, without limitation, voiding the distribution and returning our assets or shares and subjecting WDC and/or us to liability.

The distribution of our common stock was also subject to state corporate distribution statutes. Under applicable Delaware law, including the DGCL, a corporation may only pay a distribution of common stock to its stockholders if (1) after giving effect to the consummation of the transaction (a) the assets of each company, at a fair valuation, exceed its respective debts (including contingent liabilities), (b) each company will be able to pay its respective debts (including contingent liabilities) as they become due and (c) neither company will have an unreasonably small amount of either assets or capital for the operations of the businesses in which it is engaged or in which management has indicated it intends to engage and (2) immediately prior to giving effect to the distribution and pursuant to Section 170 of the DGCL, the surplus of the company declaring the distribution exceeds the net amount of the distribution less any dividend paid to the company declaring the distribution. Although WDC made the distribution of our common stock entirely out of surplus and we and WDC obtained solvency opinions from an independent appraisal firm, we and WDC cannot ensure that a court would reach the same conclusion in determining the availability of surplus for the separation and the distribution to WDC’s stockholders.

In connection with the spin-off, certain of our executive officers and directors may have actual or potential conflicts of interest because of their previous positions at WDC.

Because of their current or former positions with WDC, certain of our executive officers and directors own equity interests in WDC. Following the spin-off, even though our board of directors currently consists of a majority of directors who are independent, and our executive officers who were employees of WDC prior to the completion of the spin-off ceased to be employees of WDC upon the spin-off, some of our executive officers and directors continue to have financial interests in shares of WDC common stock and equity awards. Specifically, each outstanding WDC equity award held by our employees at the level of vice president and above was converted into both a post-separation WDC award relating to shares of WDC common stock and a Sandisk award relating to shares of our common stock at the time of separation. Continuing ownership of shares of WDC common stock and equity awards could create, or appear to create, potential conflicts of interest if we and WDC pursue the same corporate opportunities or face decisions that could have different implications for us and WDC.

We may have received better terms from unaffiliated third parties than the terms we received in our agreements with WDC.

The agreements we entered into with WDC in connection with the spin-off, including the ancillary agreements, were prepared in the context of our spin-off from WDC while we were still a wholly owned subsidiary of WDC. Accordingly, during the period in which the terms of those agreements were prepared, we did not have a board of directors or management team that was independent of WDC. While the parties believe the terms reflect arm’s-length terms, there can be no assurance that we would not have received better terms from unaffiliated third parties than the terms we received in our agreements with WDC. For more information, see the section of this prospectus entitled “Certain Relationships and Related Transactions—Material Agreements with WDC.”

Some contracts and other assets which needed to be transferred or assigned from WDC or its affiliates to us in connection with our spin-off from WDC may require the consent of a third party. If such consent is not given, we may not be entitled to the benefit of such contracts and other assets in the future, which could adversely impact our financial condition and future results of operations.

In connection with our spin-off from WDC, a number of contracts and licenses with third parties and other assets were to be transferred or assigned from (x) WDC or its affiliates to us or our subsidiaries or (y) us or our affiliates to WDC or its subsidiaries. However, the transfer or assignment of certain of these contracts, licenses or assets may still require the consent of a third party to such a transfer or assignment. Similarly, in some circumstances, we and another business unit of WDC are joint beneficiaries of contracts, and we or WDC will need to (x) enter into a new agreement with the third party to replicate the existing contract, (y) be assigned and delegated the portion of the existing contract related to the applicable business or (z) use commercially reasonable efforts to provide for an alternative arrangement to obtain the same or reasonably similar benefits and burdens of the applicable portion of the existing contract. It is possible that some parties may use the requirement of a consent or the fact that the spin-off occurred to seek more favorable contractual terms from us, to terminate the contract or license or to otherwise request additional accommodations, commitments or other agreements from us. If we are unable to obtain such consents on commercially reasonable and satisfactory terms or if the contracts are terminated, we may be unable to obtain the benefits, assets and contractual commitments which are intended to be allocated to us as part of our spin-off from WDC. The failure to timely complete the assignment of existing contracts, licenses or assets, or the negotiation of new arrangements, or a termination of any of those arrangements, could have a material adverse impact on our financial condition and future results of operations. To the extent we require a specific arrangement and agree to less favorable terms in connection with obtaining any consent to retain that arrangement, the basis for that arrangement may be less favorable than previously held by us and could adversely impact our financial conditions and future results of operations. In addition, where we do not intend to obtain consent from third-party counterparties based on our belief that no consent is required, the third-party counterparties may challenge a transfer of assets on the basis that the terms of the applicable commercial arrangements require the third-party counterparties’ consent. We may incur substantial litigation and other costs in connection with any such claims and, if we do not prevail, our ability to use these assets could be materially and adversely impacted.

If our cash flow from operations is less than we anticipate, or if our cash requirements are more than we expect, we may require additional access to capital and may need to incur additional debt or raise additional funds.

If our cash flow from operations is less than we anticipate, or if our cash requirements are more than we expect, we may require additional access to capital and may need to incur additional debt or raise additional funds. However, debt or equity financing may not be available to us on terms acceptable or favorable to us, if at all, and will depend on a number of factors, many of which are beyond our control, such as the state of the credit and financial markets and other economic, financial and geopolitical factors. If we incur additional debt or raise capital through the issuance of preferred stock, the terms of the debt or preferred stock issued may give the holders thereof rights, preferences and privileges senior to those of holders of our common stock, particularly in the event of liquidation. The terms of such debt may also impose additional and more stringent restrictions on our operations than we are currently subject to. If we raise funds through the issuance of additional equity, your percentage ownership in us would be diluted. If we are unable to raise additional capital when needed, it could affect our financial condition, which could adversely impact your investment in us.

We share certain directors with WDC, which overlap may give rise to conflicts.

There is an overlap between certain of our directors and directors of WDC. Shared directors may have actual or apparent conflicts of interest with respect to matters involving or affecting each of WDC and Sandisk. For example, there is a potential for a conflict of interest when we on the one hand, and WDC and its respective subsidiaries and successors on the other hand, are party to commercial transactions concerning the same or adjacent investments. In addition, certain of our directors continue to own shares or equity awards of WDC. These ownership interests could create actual, apparent or potential conflicts of interest when these individuals are faced with decisions that could have different implications for our company and WDC. See “Certain Relationships and Related Party Transactions—Procedures for Approval of Related Person Transactions” for a discussion of certain procedures we institute to help ameliorate such potential conflicts that may arise.

The separation may result in disruptions to relationships with customers, suppliers and other business partners.

While we intend to manage our operations to minimize any disruptions to our customers, suppliers and business partners, uncertainty related to the separation may nevertheless lead to disruption in those relationships. These disruptions, if not managed by us, could have an adverse effect on our business, financial condition, results of operations and prospects.

We may be unable to make, on a timely or cost-effective basis, the changes necessary to operate as an independent company.

To operate as an independent company, we rely on WDC to provide certain transitional services, including with respect to the functionality and reliability of our information technology systems. We need additional personnel or third-party service providers to successfully operate our business. We entered into a transition services agreement with WDC pursuant to which we provide certain services to WDC, and WDC provides certain services to us, to allow us to continue to operate in substantially the same manner following the separation and to benefit from the continuation of certain services for a certain amount of time post-separation and certain cost efficiencies in sharing certain resources and personnel. We cannot assure you that we will be able to continue to successfully implement the infrastructure or retain or hire the personnel necessary to operate as a separate company or that we will not incur costs in excess of anticipated costs to establish such infrastructure and retain or hire such personnel.

Risks Related to Our Common Stock

Our stock price may fluctuate significantly, which may make it difficult for you to resell the common stock when you want or at prices you find attractive.

The market price of our common stock may fluctuate significantly due to a number of factors, some of which may be beyond our control, including:

| • |  | our business profile, market capitalization or capital allocation policies may not fit the investment objectives of pre-spin-off WDC stockholders, causing a shift in our investor base and our common stock may not be included in some indices in which WDC common stock is included, causing certain holders to sell their shares;

| • |  | our quarterly or annual earnings, or those of other companies in its industry;

| • |  | the failure of securities analysts to cover our common stock;

| • |  | actual or anticipated fluctuations in our operating results;

| • |  | changes in earnings estimates by securities analysts or our ability to meet those estimates;

| • |  | our ability to meet our forward looking guidance;

| • |  | the operating and stock price performance of other comparable companies;

| • |  | overall market fluctuations and domestic and worldwide economic conditions; and

| • |  | other factors described in these “Risk Factors” and elsewhere in this prospectus.

Stock markets in general have experienced volatility that has often been unrelated to the operating performance of a particular company. Broad market and industry factors may materially harm the market price of our common stock, regardless of our operating performance. In the past, following periods of volatility in the market price of a company’s securities, shareholder derivative lawsuits and/or securities class action litigation has often been instituted against such company. Such litigation, if instituted against us, could result in substantial costs and a diversion of management’s attention and resources.

In addition, investors may have difficulty accurately valuing our common stock. Investors often value companies based on the stock prices and results of operations of other comparable companies. Investors may find it difficult to find comparable companies and to accurately value our common stock, which may cause the trading price of our common stock to fluctuate.

The selling stockholder owns 28,827,787 shares of our common stock. We are registering on a registration statement on Form S-1, of which this prospectus forms a part, such shares under the terms of a stockholder’s and registration rights agreement between us and the selling stockholder. The sale of such shares in one or more offerings may cause our stock price to decline.

Any sales of substantial amounts of our common stock in the public market or the perception that such sales might occur, in connection with this offering or otherwise, may cause the market price of our common stock to decline. Upon completion of the offering, we will continue to have an aggregate of approximately 145 million shares of our common stock issued and outstanding. The shares of our common stock will be freely tradeable without restriction or further registration under the Securities Act of 1933, as amended (the “Securities Act”), unless the shares are owned by one of our “affiliates,” as that term is defined in Rule 405 under the Securities Act.

Following the distribution, WDC, the selling stockholder, retained 19.9% of our common stock and may have adverse tax consequences if that stake is not disposed of within 12 months of the distribution. WDC will dispose of such shares of our common stock that it owns after the distribution through one or more subsequent exchanges

##### Table of Contents

of our common stock for WDC debt held by WDC creditors and/or through distributions of our common stock to WDC stockholders as dividends or in exchange for outstanding shares of WDC common stock, in each case during the 12-month period following the distribution. Any disposition by WDC, or any significant stockholder, of our common stock, or the perception that such dispositions could occur, could adversely affect prevailing market prices for our common stock.

We do not intend to pay cash dividends for the foreseeable future.

The timing, declaration, amount and payment of future dividends to stockholders falls within the discretion of our board of directors and will depend on many factors, including our financial condition, earnings, capital requirements of our business and covenants associated with debt obligations, as well as legal requirements, regulatory constraints, industry practice and other factors that our board of directors deems relevant. We do not intend to, and there can be no assurance that we will, pay any dividend in the future.

Your percentage of ownership in us may be diluted in the future.

Your percentage ownership in us may be diluted because of equity issuances for acquisitions, capital market transactions or otherwise, including, without limitation, equity awards that we may grant to our directors, officers and employees.

Our charter authorizes us to issue, without the approval of our stockholders, one or more classes or series of preferred stock having such designation, powers, preferences, and relative, participating, optional and other special rights, including preferences over our common stock respecting dividends and distributions, as our board of directors generally may determine. The terms of one or more classes or series of preferred stock could dilute the voting power or reduce the value of our common stock. For example, we could grant the holders of preferred stock the right to elect some number of our directors in all events or on the happening of specified events or to veto specified transactions. Similarly, the repurchase or redemption rights or liquidation preferences we could assign to holders of preferred stock could affect the residual value of our common stock. See the section entitled “Description of Sandisk Corporation Capital Stock.”

Provisions of Delaware law, our certificate of incorporation and our bylaws may prevent or delay an acquisition of our company, which could decrease the market price of our common stock.

Delaware law, our certificate of incorporation and our bylaws each contain provisions that are intended to deter coercive takeover practices and inadequate takeover bids by making such practices or bids unacceptably expensive to the bidder and to encourage prospective acquirers to negotiate with our board of directors rather than to attempt a hostile takeover. These provisions include, among others:

| • |  | provisions regarding the election of directors, classes of directors, the term of office of directors and the filling of director vacancies;

| • |  | no cumulative voting;

| • |  | removal of directors either with or without cause, by the affirmative vote of the stockholders then entitled to vote at an election of directors having a majority of the voting power of the Company;

| • |  | our board of directors has the authority to determine designations and the powers, preferences and relative, participating, optional or other special rights, and qualifications, limitations or restrictions thereof, including, without limitation, the dividend rate, conversion rights, redemption price and liquidation preference, of any series of shares of preferred stock, and to fix the number of shares constituting any such series, and to increase or decrease the number of shares of any such series (but not below the number of shares thereof then outstanding);

37

##### Table of Contents

| • |  | advance notice requirements applicable to stockholders for director nominations and actions to be taken at annual meetings; and

| • |  | our bylaws may be altered, amended or repealed, and new bylaws may be adopted, (i) by our board of directors, by vote of a majority of the number of directors then in office as directors, acting at any duly called and held meeting of our board of directors, or (ii) by our stockholders; provided that notice of such proposed amendment, modification, repeal or adoption is given in the notice of special meeting. To the extent permitted by law, any bylaws made or altered by the stockholders may be altered or repealed by either our board of directors or the stockholders.

Public stockholders who might desire to participate in these types of transactions may not have an opportunity to do so, even if the transaction is considered favorable to stockholders. These anti-takeover provisions could substantially impede the ability of public stockholders to benefit from a change in control or a change in our management and board of directors and, as a result, may adversely affect the market price of our common stock and your ability to realize any potential change of control premium.

In addition, we are subject to Section 203 of the DGCL. Section 203 of the DGCL protects publicly traded Delaware corporations, such as us following the distribution, from hostile takeovers and from actions following a hostile takeover, by prohibiting some transactions once a potential acquirer has gained a significant holding in the corporation. Subject to certain exceptions, the statute prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years after the date of the transaction in which the person became an interested stockholder, unless:

| • |  | prior to such date, the board of directors of such corporation approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;

| • |  | upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of such corporation outstanding at the time the transaction commenced (excluding for purposes of determining the number of shares outstanding (but not the outstanding voting stock owned by the interested stockholder), those shares owned by (i) persons who are directors and also officers and (ii) employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer); or

| • |  | on or after such date the business combination is approved by the board of directors of such corporation and authorized at an annual or special meeting of stockholders and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock that is not owned by the interested stockholder.

For purposes of Section 203 of the DGCL, a “business combination” includes a merger, asset sale or other transaction resulting in a financial benefit to the interested stockholder, with an “interested stockholder” being defined as a person who, together with affiliates and associates, owns (or who is an affiliate or associate of the corporation and did own within three years prior to the date of determination whether the person is an “interested stockholder”) 15% or more of the corporation’s voting stock.

A corporation may elect not to be governed by Section 203 of the DGCL. Neither our certificate of incorporation nor our bylaws contains the election not to be governed by Section 203 of the DGCL. Therefore, we are governed by Section 203 of the DGCL.

We believe these provisions protect our stockholders from coercive or otherwise unfair takeover tactics by requiring potential acquirers to negotiate with our board of directors and by providing our board of directors with more time to assess any acquisition proposal. These provisions are not intended to make us immune from takeovers. However, these provisions will apply even if the offer may be considered beneficial by some

stockholders and could delay or prevent an acquisition that our board of directors determines is not in the best interests of us and our stockholders. These provisions may also prevent or discourage attempts to remove and replace incumbent directors.

Our certificate of incorporation contains an exclusive forum provision that could limit a stockholder’s ability to bring a claim in a judicial forum that the stockholder believes is favorable for such disputes and may discourage lawsuits against us and any of our directors, officers or other employees.

Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or the federal district court in the State of Delaware if the Court of Chancery does not have subject matter jurisdiction) is the sole and exclusive forum for (i) any derivative action brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our current or former director, officer or other employee or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law or our certificate of incorporation or bylaws or (iv) any action asserting a claim governed by the internal affairs doctrine (the “Delaware Exclusive Forum Provision”). Our certificate of incorporation further provides that, unless we consent in writing to the selection of an alternative forum, the federal district courts of the United States of America shall be, to the fullest extent permitted by law, the exclusive forum for resolving any complaint asserting a cause of action under the Securities Act (the “Federal Forum Provision”).

The Delaware Exclusive Forum Provision is intended to apply to claims arising under Delaware state law and would not apply to claims brought pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or any other claim for which the federal courts have exclusive jurisdiction. In addition, the Federal Forum Provision is intended to apply to claims arising under the Securities Act and would not apply to claims brought pursuant to the Exchange Act. The exclusive forum provisions we included in our certificate of incorporation will not relieve us of our duties to comply with the federal securities laws and the rules and regulations thereunder and, accordingly, actions by our stockholders to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder must be brought in federal courts. Our stockholders are not deemed to have waived our compliance with these laws, rules and regulations.

The exclusive forum provisions we included in our certificate of incorporation may limit a stockholder’s ability to bring a claim in a judicial forum of its choosing for disputes with the company or its directors, officers or other employees, which may discourage lawsuits against us and our directors, officers and other employees. In addition, stockholders who do bring a claim in the Court of Chancery of the State of Delaware pursuant to the Delaware Exclusive Forum Provision could face additional litigation costs in pursuing any such claim, particularly if they do not reside in or near Delaware. The court in the designated forum under our exclusive forum provisions may also reach different judgments or results than would other courts, including courts where a stockholder would otherwise choose to bring the action, and such judgments or results may be more favorable to us than to our stockholders. Further, the enforceability of similar exclusive forum provisions in other companies’ organizational documents has been challenged in legal proceedings, and it is possible that a court could find any of our exclusive forum provisions to be inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings. If a court were to find all or any part of our exclusive forum provisions to be inapplicable or unenforceable in an action, we might incur additional costs associated with resolving such action in other jurisdictions.

The price of WDC’s common stock historically has been volatile, and the price of our common stock may be volatile as well. This volatility may affect the price at which you could sell your common stock, and the sale of substantial amounts of our common stock could adversely affect the price of our common stock.

The market price of WDC’s common stock has been volatile, and the price of our common stock may also be volatile. This volatility may affect the price at which you could sell your common stock. Our stock price may be subject to significant price and volume fluctuations in response to market and other factors, including:

| • |  | actual or anticipated fluctuations in our operating results, including those resulting from the seasonality and cyclicality of our business;

| • |  | perceptions about our strategic relationships and joint ventures, access to supply of NAND flash memory, new technologies and technology transitions;

| • |  | announcements of technological innovations by us or our competitors, which may decrease the volume and profitability of sales of our existing products and increase the risk of inventory obsolescence;

| • |  | new products introduced by us or our competitors;

| • |  | strategic actions by us or competitors, such as acquisitions and restructurings;

| • |  | responses to the separation;

| • |  | periods of severe pricing pressures due to oversupply or price erosion resulting from competitive pressures or industry consolidation;

| • |  | developments with respect to patents or proprietary rights, and any litigation;

| • |  | proposed or adopted regulatory changes or developments or anticipated or pending investigations, proceedings or litigation that involve or affect us or our competitors;

| • |  | conditions and trends in the flash memory, computer, mobile, data and content management, storage and communication industries;

| • |  | contraction in our operating results or growth rates that are lower than our previous high growth rate periods;

| • |  | failure to meet analysts’ revenue or earnings estimates or changes in financial estimates or publication of research reports and recommendations by financial analysts relating specifically to us or the storage industry in general;

| • |  | announcements relating to dividends and share repurchases; and

| • |  | macroeconomic conditions that affect the market generally and, in particular, developments related to market conditions for our industry.

In addition, the sale of substantial amounts of shares of our common stock, or the perception that these sales may occur, could adversely affect the market price of our common stock. Further, the stock market is subject to fluctuations in the stock prices and trading volumes that affect the market prices of the stock of public companies, including us. These broad market fluctuations have adversely affected and may continue to adversely affect the market price of shares of our common stock. For example, expectations concerning general economic conditions may cause the stock market to experience extreme price and volume fluctuations from time to time that particularly affect the stock prices of many high technology companies. These fluctuations may be unrelated to the operating performance of the companies.

Securities class action lawsuits are often brought against companies after periods of volatility in the market price of their securities, and any such lawsuits filed against us could result in substantial costs and a diversion of resources and management’s attention.

Tax matters may materially affect our financial position and results of operations.

Changes in tax laws in the United States, the European Union and around the globe have impacted and will continue to impact our effective worldwide tax rate, which may materially affect our financial position and results of operations. Further, the majority of countries in the G20 and Organization for Economic Cooperation and Development Inclusive Framework on Base Erosion and Profit Shifting have agreed to adopt a two-pillar approach to taxation, which includes the implementation of a global corporate minimum tax rate of 15%, which when effective could materially increase our tax obligations in these countries. Due to the large scale of our U.S. and international business activities, many of these enacted and proposed changes to the taxation of our activities, including cash movements, could increase our worldwide effective tax rate and harm our business. The Tax Cuts and Jobs Act of 2017 eliminated the option to deduct research and development expenditures in the year incurred, requiring amortization in accordance with Section 174 of the Internal Revenue Code. Depending on our operating results, this requirement could materially increase our effective tax rate and reduce our operating cash flows. Additionally, portions of our operations are subject to a reduced tax rate or are free of tax under various tax holidays that expire in whole or in part from time to time, or may be terminated if certain conditions are not met. Although many of these holidays may be extended when certain conditions are met, we may not be able to meet such conditions. If the tax holidays are not extended, or if we fail to satisfy the conditions of the reduced tax rate, then our effective tax rate could increase in the future. Our determination of our tax liability in the U.S. and other jurisdictions is subject to review by applicable domestic and foreign tax authorities. Although we believe our tax positions are properly supported, the final timing and resolution of any tax examinations are subject to significant uncertainty and could result in litigation or the payment of significant amounts to the applicable tax authority in order to resolve examination of our tax positions, which could result in an increase of our current estimate of unrecognized tax benefits and may harm our business.

If securities or industry analysts do not publish research or reports about our business, or if they downgrade their recommendations regarding our common stock, our stock price and trading volume could decline.

The trading market for our common stock is influenced by the research and reports that industry or securities analysts publish about us or our business. If any of the analysts who may cover us downgrade our common stock or publish inaccurate or unfavorable research about our business, our common stock price may decline. If analysts cease coverage of us or fail to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause our common stock price or trading volume to decline and our common stock to be less liquid.

Provisions in our joint venture agreements with Kioxia may deter, prevent or delay an acquisition of us, which could decrease the market price of our common stock and limit our future strategic opportunities.

The joint venture agreements with Kioxia contain provisions that may deter, prevent or delay third parties from acquiring us. These provisions include, among others:

| • |  | restrictions limiting our ability and the ability of any of our affiliates to manufacture or have a third party fabricate flash memory outside of Flash Ventures’ Yokkaichi and Kitakami facilities;

| • |  | restrictions limiting our ability and the ability of any of our affiliates to fabricate flash memory beyond our share of Flash Ventures’ manufacturing capacity; and

| • |  | restrictions limiting our ability to transfer equity in the Flash Ventures entities or their assets, particularly partial transfers.

If we nevertheless wanted to pursue a transaction providing for our acquisition by a third party, the provisions in our joint venture agreements with Kioxia could deter, prevent or delay a potential acquiror from pursuing such a transaction, even if the transaction is considered favorable to our stockholders.

41

##### Table of Contents

We may seek a waiver of applicable provisions of the joint venture agreements from Kioxia or Kioxia’s consent with respect to such a transaction, but there is no guarantee that we will successfully obtain Kioxia’s consent or waiver.

The provisions in our joint venture agreements with Kioxia could substantially impede the ability of public stockholders to benefit from future strategic transactions, including an acquisition of Sandisk and, as a result, may adversely affect the market price of our common stock and your ability to realize any potential change of control premium.

THE SEPARATION AND DISTRIBUTION

Overview

On October 30, 2023, WDC announced its intention to separate its Flash Business from its HDD Business. WDC determined to implement this separation through the spin-off of WDC’s Flash Business to its stockholders. Sandisk was formed to hold WDC’s Flash Business. Following the separation, we hold the assets and liabilities of WDC related to its Flash Business, subject to certain limited exceptions. After the separation, WDC continues to hold its HDD Business.

On January 25, 2025, the WDC Board of Directors approved the distribution of 80.1% of Sandisk’s issued and outstanding shares of common stock held by WDC to WDC stockholders on the basis of one share of our common stock for every three shares of WDC common stock held as of 1:00 p.m. Pacific time on February 12, 2025, the Record Date for the distribution, subject to certain conditions.

On February 21, 2025, the distribution was effected and the separation became effective as of 11:59 p.m. Pacific time. To effect the separation, WDC undertook a series of internal restructuring transactions to separate the assets, liabilities and certain legal entities of WDC associated with the Flash Business to us, in exchange for a cash payment of approximately $1.5 billion by us to WDC with a portion of the net proceeds of the Term Loan Facility as further described below under “Financing Transactions.” In connection with the distribution, we incurred $2.0 billion of indebtedness. In conjunction with the separation, 116,035,464 shares of our common stock were distributed to WDC stockholders, as described below. Additionally, WDC retained 28,827,787 shares of our common stock representing its 19.9% retained interest. “Regular-way” trading of our common stock began with the opening of the Nasdaq on February 24, 2025, under the ticker symbol “SNDK.” Our common stock has a par value of $0.01 per share.

On February 21, 2025, the distribution date, each WDC stockholder of record as of the Record Date received one share of our common stock for every three shares of WDC common stock held as of the Record Date, as described below. WDC stockholders received cash in lieu of any fractional shares of Sandisk common stock that they would have received after application of this ratio. Upon completion of the separation, each WDC stockholder as of the Record Date continued to own shares of WDC and owned a proportionate share of the outstanding common stock of Sandisk distributed in the distribution. WDC stockholders were not required to make any payment, surrender or exchange their WDC common stock or take any other action to receive their shares of our common stock in the distribution.

Following the distribution, our stockholders (other than WDC) own directly 80.1% of the outstanding shares of our common stock and WDC retained 19.9% of the outstanding shares of our common stock. WDC (the selling stockholder named herein) intends to dispose of all of our common stock that it retains through one or more subsequent exchanges of our common stock for WDC debt held by WDC creditors and/or through distributions of our common stock to WDC stockholders as dividends or in exchange for outstanding shares of WDC common stock, in each case during the 12-month period following the distribution.

We are registering on a registration statement on Form S-1, of which this prospectus forms a part, the shares retained by WDC under the terms of a stockholder’s and registration rights agreement between us and the selling stockholder.

Formation of Sandisk Corporation

In connection with the separation, WDC incorporated Sandisk as a Delaware corporation on February 5, 2024, for the purpose of transferring to Sandisk certain assets and liabilities, including certain entities holding assets and liabilities, associated with the Flash Business.

Internal Reorganization

As part of the separation, and prior to the distribution, WDC and its subsidiaries completed an internal reorganization in order to transfer to us the Flash Business that we hold following the separation. Among other things and subject to certain limited exceptions, the internal reorganization resulted in us owning, directly or indirectly, the operations comprising, and the entities that conduct, the Flash Business.

The internal reorganization included a series of restructuring transactions pursuant to which (i) WDC and its subsidiaries transferred the assets and liabilities associated with the Flash Business to Sandisk or certain entities which became its subsidiaries and transferred the equity interests of certain entities holding such assets and liabilities to Sandisk and (ii) Sandisk and its subsidiaries transferred the assets and liabilities associated with the HDD Business that are held by our subsidiaries, if any, to WDC or its subsidiaries, in each case, as set forth in the separation and distribution agreement. WDC and its subsidiaries also transferred certain other corporate and shared assets and liabilities to Sandisk (or certain entities which became its subsidiaries) and Sandisk and its subsidiaries also transferred certain other corporate and shared assets and liabilities to WDC or its subsidiaries, in each case, pursuant to the terms of the separation and distribution agreement. In exchange for the transfer of the foregoing assets, liabilities and legal entities associated with the Flash Business to us, we paid WDC a cash payment in an amount equal to approximately $1.5 billion. Following such internal reorganization transaction, WDC continued to hold the HDD Business. We also entered into certain financing arrangements and incurred certain indebtedness prior to and in connection with the separation. See the section of this prospectus entitled “Description of Material Indebtedness” for more information.

Results of the Distribution

Following the separation and the distribution, we became a separate, publicly traded company.

We entered into a separation and distribution agreement and other related agreements with WDC to effect the separation and provide a framework for our transitional relationship with WDC following the separation. These agreements provide for the allocation between us and WDC of WDC’s assets, liabilities and obligations (including employee benefits, intellectual property, equipment sharing and tax-related assets and liabilities) attributable to periods prior to our separation from WDC and govern the relationship between us and WDC following the separation. For a more detailed description of these agreements, see “Certain Relationships and Related Party Transactions.”

Market for Sandisk Common Stock

Our common stock is listed on Nasdaq under the symbol “SNDK.” We did not set the initial price of shares of our common stock. The initial price was established by the public markets.

The price at which shares of our common stock trade may fluctuate significantly, particularly until an orderly public market develops. Trading prices for our common stock will be determined in the public markets and may be influenced by many factors. See “Risk Factors—Risks Related to Our Common Stock.”

Incurrence of Debt

On February 21, 2025, we entered into the Loan Agreement. The Loan Agreement comprises the Term Loan Facility in the principal amount of $2.0 billion and the Revolving Credit Facility in the principal amount of $1.5 billion. On February 21, 2025, we borrowed $2.0 billion under the Term Loan Facility. There were no amounts outstanding as of April 30, 2025 under the Revolving Credit Facility. For a more detailed description of the Facilities, see the section of this prospectus entitled “Description of Material Indebtedness” on page 150.

MARKET PRICE OF SHARES

Our shares of common stock have been listed and traded on the Nasdaq under the symbol “SNDK” since February 24, 2025, which was the next trading day following the distribution. On April 30, 2025 the last sale price of our shares as reported on the Nasdaq was $32.11 per share. As of April 30, 2025, there were approximately 684 holders of record of our shares. Because many of our shares are held by brokers and other institutions on behalf of stockholders, we are unable to estimate the total number of stockholders represented by these recordholders.

DIVIDEND POLICY

We do not currently intend to pay any cash dividends in the foreseeable future. We currently intend to retain all available funds and future earnings, if any, for the operation of our business and to strengthen our financial position and flexibility. The payment of cash dividends in the future will be dependent upon our revenue and earnings, capital requirements and general financial condition and results of operations, as well as applicable law, regulatory constraints, industry practice and other business considerations determined by our board of directors to be relevant. The payment of any cash dividends will be within the discretion of our Board of Directors. In addition, the terms governing our current or future debt may also limit or prohibit dividend payments. Accordingly, we cannot guarantee that we will ever pay dividends in the future or that we would continue to pay any dividends that we may commence in the future.

In addition, under Delaware law, our Board of Directors may declare dividends only to the extent of our surplus (which is defined as total assets at fair market value, minus total liabilities, minus statutory capital) or, if there is no surplus, out of our net profits for the then-current and/or immediately preceding fiscal year.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The following unaudited pro forma condensed combined financial statements give effect to the spin-off and related adjustments in accordance with Article 11 of the SEC’s Regulation S-X, as amended. The spin-off and related transactions are described in the section of this prospectus entitled “The Separation and Distribution.”

The following unaudited pro forma condensed combined financial statements consist of the unaudited pro forma condensed combined balance sheet as of December 27, 2024, and the unaudited pro forma condensed combined statement of operations for the six months ended December 27, 2024 and for the fiscal year ended June 28, 2024.

The unaudited pro forma condensed combined financial statements and Sandisk’s combined financial statements and notes thereto included in this prospectus shall mean the Flash Business of Western Digital Corporation and references to “Parent” or “WDC” shall mean Western Digital Corporation.

The unaudited pro forma condensed combined financial statements reflect adjustments to our historical unaudited combined balance sheet as of December 27, 2024, and our historical unaudited combined statement of operations for the six months ended December 27, 2024 and audited combined statement of operations for the fiscal year ended June 28, 2024. The unaudited pro forma condensed combined balance sheet as of December 27, 2024, gives effect to the spin-off and related transactions, described below, as if they occurred on December 27, 2024. The unaudited pro forma condensed combined statement of operations for the six months ended December 27, 2024 and for the fiscal year ended June 28, 2024, gives effect to the spin-off and related transactions as if they had occurred on July 1, 2023, the beginning of our most recently completed fiscal year.

The unaudited pro forma condensed combined financial statements have been prepared to include Financing / Capitalization Adjustments and Spin-off Adjustments, collectively “Transaction Accounting Adjustments” and Autonomous Entity Adjustments to reflect our financial condition and results of operations as if we were a separate standalone public company. The unaudited pro forma combined financial statements have been adjusted to give effect to the following (collectively, the “Pro Forma Transactions”):

| • |  | the contribution of the assets and liabilities that comprise our business by WDC to us pursuant to the separation and distribution agreement and the retention by WDC of certain specified assets and liabilities reflected in our historical combined financial statements, in each case, pursuant to the separation and distribution agreement;

| • |  | the effect of our post-spin-off capital structure, including the incurrence of indebtedness in an aggregate principal amount equal to approximately $2.0 billion pursuant to the debt financing transactions and the application of the net proceeds from the debt financing transactions as described in the section of this prospectus entitled “Description of Material Indebtedness”;

| • |  | the one-time expenses associated with the spin-off and related transactions and the transition to becoming a standalone public company;

| • |  | the impact of the ancillary agreements and the provisions contained therein (see “Material Agreements with WDC” within this prospectus); and

| • |  | other adjustments as described in the accompanying notes to the unaudited pro forma condensed combined financial statements.

On September 28, 2024, a wholly owned subsidiary of Sandisk completed the sale of 80% of its equity interest in the SDSS Venture. Following the closing of this transaction, Sandisk will account for its retained investment in the SDSS Venture under the equity method of accounting. The SDSS Venture and its associated results of operations are included within Sandisk’s historical combined financial statements. As the divestiture is not significant to Sandisk and impacts to our cost of inventory and gross profit margins are not expected to be material, we have not adjusted the unaudited pro forma condensed combined financial information herein. See Note 9, “Related Parties and Related Commitments and Contingencies” in the Notes to the unaudited Combined Financial Statements for further information.

We entered into an intellectual property cross license agreement and transitional trademark license agreement with WDC in connection with the spin-off transaction. As the intellectual property cross license agreement provides a royalty-free license and any royalty fees due under the trademark license agreement would not commence until up to 18 months after the effective date of the spin-off, we have not adjusted the unaudited pro forma condensed combined financial information herein.

The unaudited pro forma condensed combined financial statements are subject to the assumptions and adjustments described in the accompanying notes. The pro forma adjustments are based on available information and assumptions we believe are reasonable; however, such adjustments are subject to change.

The unaudited pro forma condensed combined financial information is for illustrative and informational purposes only. The unaudited pro forma condensed combined financial information may not necessarily reflect what our financial condition, results of operations or cash flows would have been had we been a standalone public company during the periods presented, or what our financial condition, results of operations and cash flows may be in the future. In addition, the unaudited pro forma condensed combined financial information has been derived from our historical combined financial statements, which have been prepared from WDC’s historical accounting records. All the allocations and estimates in our historical combined financial statements are based on assumptions that management believes are reasonable.

Our historical combined financial statements, which were the basis for the unaudited pro forma condensed combined financial information, were prepared on a carve-out basis as we did not operate as a separate, independent company for the periods presented. Accordingly, such financial information reflects an allocation of certain corporate costs, such executive management, finance, tax, legal, information technology, employee benefits administration, treasury, risk management, procurement and other shared services. These corporate expenses have been allocated to Sandisk based upon direct usage or benefit, where identifiable, with the remainder allocated based upon headcount, revenue or other relevant measures. See Note 1, “Basis of Presentation” and Note 9, “Related Parties and Related Commitments and Contingencies” to the audited combined financial statements included elsewhere in this prospectus for further information on the allocation of corporate costs.

We incur incremental costs as a standalone public company related to certain expenses previously allocated from WDC. Our historical combined financial statements include allocations for certain costs of support functions that are provided on a centralized or geographic basis by WDC and its affiliates, which include executive management, finance, tax, legal, information technology, employee benefits administration, treasury, risk management, procurement and other shared services. Additionally, we incurred charges from contracts with vendors in relation to the separation of Sandisk as a standalone public company. These charges primarily relate to legal, audit and advisory fees, system implementation costs, business separation costs and other costs. We also incur new costs relating to our public reporting and compliance obligations as a standalone public company. Any shortfall of required resource needs are and will be filled through external hiring or are and will be supported by WDC through the transition services agreement. These incremental costs began to materialize on the date of the completion of the separation.

Adverse effects and limitations, including those discussed in the section of this prospectus entitled “Risk Factors,” may impact the actual costs incurred. We are in process of evaluating the extent and timing of such costs to be incurred as a standalone public company and accordingly have not reflected any management adjustments for such costs within the unaudited condensed combined pro forma financial information presented below.

The unaudited pro forma condensed combined financial information reported below should be read in conjunction with the section of this prospectus entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the historical combined financial statements included elsewhere in this prospectus.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The unaudited pro forma condensed combined balance sheet as of December 27, 2024, and the unaudited pro forma condensed combined statement of operations for the six months ended December 27, 2024 and for the fiscal year ended June 28, 2024, include the following adjustments:

Note 1. Transaction Accounting Adjustments

Financing / Capitalization Adjustments

A. | Reflects $2,000 million of borrowings incurred in connection with the spin-off pursuant to the debt financing transactions, offset by term loan and revolving credit facility debt issuance costs of $24 million and $8 million, respectively, and term loan original issue discount of $30 million. See “Description of Material Indebtedness” for additional details. We paid WDC, as partial consideration for the Flash Business that WDC transferred to us in connection with the spin-off, all of the net proceeds that we received from the debt financing transactions, together with any interest accrued thereon following our receipt of such proceeds, provided that we retained an amount in cash and cash equivalents of $1,339 million, after giving effect to this offering, the debt financing transactions and the settlement or termination of Notes due to (from) Parent. See “Management’s Discussion and Analysis of Financial Conditions and Results of Operations—Financial Condition, Liquidity and Capital Resources” for additional details.

The following represents adjustments to cash and cash equivalents:

(in millions) |  | As of December 27, 2024 |
Cash received from issuance of debt |  | $ | 1,970 |
Cash distribution to WDC at separation |  |  | (1,403 | )
Cash paid for debt issuance costs |  |  | (32 | )
Total pro forma adjustment to cash and cash equivalents |  | $ | 535 |

We also entered into a five-year revolving credit facility of $1,500 million; however, the facility was not drawn upon at the completion of the spin-off. The associated issuance costs are recorded in other non-current assets and amortized to interest expense over the term of the credit facility. Periodic fees payable on the undrawn portion of the revolving credit facility have also been reflected as adjustments to interest expense.

The following represents adjustments to long-term debt:

(in millions) |  | As of December 27, 2024 |
Cash received from issuance of debt |  | $ | 1,970 |
Deferred debt issuance costs for term loan |  |  | (24 | )
Total pro forma adjustment to debt |  |  | 1,946 |
Less: current portion of long-term debt |  |  | (20 | )
Total pro forma adjustment to long-term debt |  | $ | 1,926 |

B. | The adjustment reflects interest expense of $74 million for the six months ended December 27, 2024 and $150 million for the year ended June 28, 2024 based on a weighted-average term loan interest rate of approximately 7.4%. Additionally, interest expense for the six months ended December 27, 2024 and for the year ended June 28, 2024 reflects amortization of deferred debt issuance costs incurred in connection with the issuance of debt as described in Note (A) above, as well as undrawn capacity fees on the revolving credit

| facility. A 1/8 percent variance in the assumed interest rate on the floating rate indebtedness would change interest expense by $3 million and $1 million for the fiscal year ended June 28, 2024 and the six months ended December 27, 2024. Also included within the adjustment to interest expense and interest income is the elimination of interest expense and interest income, incurred in connection with Notes due to (from) Parent which were settled or terminated in connection with the spin-off.

The following represents adjustments to interest expense:

(in millions) |  | Six months ended December 27, 2024 |  |  | Year ended June 28, 2024 |
Interest expense on total debt at estimated weighted average rate of approximately 7.4% |  | $ | 74 |  |  | $ | 150 |
Undrawn capacity fee on revolving debt facility |  |  | 2 |  |  |  | 4 |
Amortization of debt issuance costs and original issue discount |  |  | 4 |  |  |  | 8 |
Elimination of interest expense on notes due to Parent |  |  | (4 | ) |  |  | (37 | )
Total pro forma adjustment to interest expense |  | $ | 76 |  |  | $ | 125 |

Spin-Off Adjustments

C. | Reflects an adjustment to remove employee deferred compensation liabilities that were retained by WDC, which are included in the historical combined balance sheet.

D. | Represents the reclassification of WDC’s net investment in Sandisk to additional paid-in capital.

E. | Reflects the issuance of 145 million shares of our common stock with a par value of $0.01 per share pursuant to the separation and distribution agreement. The remaining 19.9% of our common stock continues to be owned by WDC, which WDC will dispose of through one or more subsequent exchanges of our common stock for WDC debt held by WDC creditors and/or through distributions of our common stock to WDC stockholders as dividends or in exchange for outstanding shares of WDC common stock, in each case during the 12-month period following the distribution.

F. | Adjustments to additional paid-in-capital are summarized below:

(in millions) |  | As of December 27, 2024 |
Reclassification of WDC’s net investment in Sandisk (Note D) |  | $ | 12,435 |
Cash payment to WDC (Note A) |  |  | (1,403 | )
Settlement of Notes due to (from) Parent (Note A) |  |  | 553 |
Deferred compensation liabilities transferred to WDC (Note C) |  |  | 32 |
Common stock issuance (Note E) |  |  | (1 | )
Uncertain tax positions (Note G) |  |  | (39 | )
Transfer of investment Unis JV from Parent (Note I) |  |  | 63 |
Total pro forma adjustment to APIC |  | $ | 11,640 |

G. | Reflects an addition of liabilities related to uncertain tax provisions (“UTPs”) and associated deferred tax assets, as well as current and non-current income tax receivables, transferred to Sandisk from WDC. Additionally reflects recognition of liabilities related to indemnification granted by Sandisk to WDC related to certain tax matters. The recognition of these UTPs and deferred tax assets has no impact on the unaudited condensed combined pro forma statement of operations, as the effects of UTPs attributable to Sandisk have been reflected within our historical combined statements of operations.

##### Table of Contents

H. | Reflects cash transaction bonus expenses of $34 million paid to certain Sandisk employees in connection with the separation from WDC. See “Material Agreements with WDC—Employee Matters Agreement” for additional details of these cash transaction bonus payments.

I. | Reflects transfer of WDC’s equity investment in the Unis Venture to Sandisk in accordance with the separation and distribution agreement and associated equity method earnings.

J. | Reflects additional charges from contracts with vendors incurred related to completion of the spin-off transaction through the spin-off effective date. These charges primarily relate to legal, advisor fees, business separation and other costs. All transaction costs incurred during the six months ended December 27, 2024 and the fiscal year ended June 28, 2024 related to the spin-off are included in our historical combined statements of operations. The pro forma adjustments for the year ended June 28, 2024 include additional charges incurred between December 27, 2024, and the spin-off date of $13 million related to business separation. Actual charges that will be incurred could be different from these estimates. These costs are not expected to recur beyond 12 months after the spin-off. We have not reflected a related adjustment within our pro forma condensed combined balance sheet as of December 27, 2024, as the related liabilities were settled by WDC upon completion of the spin-off.

K. | In connection with the Separation, outstanding WDC equity awards held by certain of our employees were subject to modification and exchanged for Sandisk equity awards pursuant to the Employee Matters Agreement. This adjustment represents the impact of the exchange and amortization of the incremental fair value of the modified awards over the remaining service period.

L. | Represents the income tax impact of the transaction accounting pro forma adjustments for the six months ended December 27, 2024 and for the fiscal year ended June 28, 2024. This adjustment was primarily calculated by applying the statutory tax rates in the respective jurisdictions to each of the pre-tax pro forma adjustments in jurisdictions where valuation allowances were not required. The applicable tax rates could be impacted (either higher or lower) depending on many factors subsequent to the spin-off including the profitability in local jurisdictions and the legal entity structure implemented subsequent to the spin-off and may be materially different from the pro forma results.

Note 2. Autonomous Entity Adjustments

M. | Reflects adjustment in the unaudited pro forma condensed combined statement of operations to include the shortfall (excess) of historical compensation and benefits cost allocations compared to actual cost of certain WDC employees who were transferred to Sandisk by WDC upon effectiveness of the spin-off. This adjustment also reflects the incremental compensation expense associated with certain Sandisk executives hired after the reporting date which is partially offset by reduction of expense for the compensation and benefits associated with certain employees of Sandisk who were retained by WDC upon effectiveness of the spin-off. Additionally reflects an adjustment to include or exclude, as appropriate, associated employee-related liabilities within the unaudited pro forma condensed combined balance sheet.

|  | $ | (12 | ) |  | $ | 1 |  |  | $ | 22 |  |  | $ | 11 |

N. | Reflects $17 million for the fiscal year ended June 28, 2024, of certain transition services costs associated with the transition services agreement we entered into with WDC. The costs are primarily associated with information technology services and corporate support functions. Adjustment is presented net of $9 million in fees we expect to charge WDC under a reverse transition services agreement.

O. | Reflects the net impact of lease arrangements with third parties and sub-lease arrangements with WDC for corporate offices and data centers that have been entered into prior to the spin-off. These adjustments record the right-of-use assets and related operating lease liabilities based on the estimated present value of the lease payments over the lease term. Differences between the costs historically allocated to us and included within our historical combined statements of operations and the costs which we expect to incur as a standalone company have been reflected as an autonomous entity adjustment (see Note (Q) below).

P. | Represents the income tax impact of the autonomous entity pro forma adjustments and the expected effects of the separation and distribution agreement and the tax matters agreement for the six months ended December 27, 2024 and for the fiscal year ended June 28, 2024. This adjustment was primarily calculated by applying the statutory tax rates in the respective jurisdictions to each of the pre-tax pro forma adjustments in jurisdictions where valuation allowances were not required. The applicable tax rates could be impacted (either higher or lower) depending on many factors subsequent to the spin-off, including the profitability in local jurisdictions and the legal entity structure implemented subsequent to the spin-off, and may be materially different from the pro forma results.

Q. | This adjustment represents the difference between the historically allocated facilities expenses incurred by Sandisk and the future expected costs based upon the facilities transferred to or from Sandisk and contracts entered into by Sandisk in connection with the spin-off.

Note 3. Pro Forma Earnings (Loss) Per Share

Pro forma basic and diluted earnings (loss) per share and pro forma weighted-average basic and diluted shares outstanding for the six months ended December 27, 2024 and for the fiscal year ended June 28, 2024, reflect the number of shares of our common stock which were outstanding upon completion of the spin-off (see Note (E) above). As Sandisk has a loss in the unaudited pro forma condensed combined statement of operations for the fiscal year ended June 28, 2024, the potentially dilutive shares are anti-dilutive and therefore they are not added into the earnings per share calculation. The weighted-average number of shares used to compute pro forma diluted earnings per share for the six months ended December 27, 2024 represents the dilutive impacts of equity awards outstanding as of, or issued in connection with, the spin-off and the subsequent expected pattern of vesting for those awards under Sandisk equity-based compensation arrangements.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This section should be read in conjunction with the unaudited Condensed Combined Financial Statements and related Notes and the audited Combined Financial Statements and related Notes included in this prospectus, as well as the information contained in the sections of this prospectus titled “Unaudited Pro Forma Condensed Combined Financial Information” and “Business.” The section of this prospectus titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” contains forward-looking statements. See the sections of the prospectus titled “Cautionary Statement Concerning Forward-Looking Statements” and “Risk Factors” for a discussion of the uncertainties, risks and assumptions associated with these forward-looking statements that could cause future results to differ materially from those reflected in this section.

The unaudited Condensed Combined Financial Statements and audited Combined Financial Statements included in this prospectus have been derived from WDC’s historical accounting records and are presented on a standalone basis as if Sandisk’s operations had been conducted independently from WDC. The unaudited Condensed Combined Financial Statements and audited Combined Financial Statements have been prepared in accordance with GAAP, by aggregating financial information from the components of Sandisk and WDC’s accounting records directly attributable to Sandisk.

The unaudited Condensed Combined Statements of Operations and audited Combined Statements of Operations include all revenues and costs directly attributable to Sandisk, including costs for facilities, functions and services used by Sandisk. Sandisk’s business has historically functioned together with the other businesses controlled by WDC. Accordingly, Sandisk relied on WDC’s corporate overhead and other support functions for its business. Therefore, certain corporate overhead and shared costs have been allocated to Sandisk including (i) certain general and administrative expenses related to WDC support functions that are provided on a centralized basis within WDC (e.g., expenses for corporate facilities, executive oversight, treasury, finance, legal, human resources, compliance, information technology, employee benefit plans, stock compensation plans and other corporate functions) and (ii) certain operations support costs incurred by WDC, including product sourcing, maintenance and support services and other supply chain functions. These expenses have been specifically identified, when possible, or allocated based on revenues, headcount, usage or other allocation methods that are considered to be a reasonable reflection of the utilization of services provided or benefit received. Management considers that such allocations have been made on a reasonable basis consistent with benefits received but may not necessarily be indicative of the costs that would have been incurred if Sandisk had been operated on a standalone basis for the periods presented.

Our discussion within MD&A is organized as follows:

| • |  | Overview. This section contains background information on Sandisk, summary of significant themes and events during the year as well as strategic initiatives and trends in order to provide context for management’s discussion and analysis of our financial condition and results of operations.

| • |  | Results of operations. This section contains an analysis of our results of operations presented in the accompanying unaudited Condensed Combined Statements of Operations by comparing the results for the six months ended December 27, 2024 to the results for the six months ended December 29, 2023. Additionally, this section also contains an analysis of our results of operations presented in the accompanying audited Combined Statements of Operations by comparing the results for the fiscal year ended June 28, 2024 to the results for the fiscal year ended June 30, 2023, and the results for the fiscal year ended July 1, 2022.

| • |  | Financial condition, liquidity and capital resources. This section provides an analysis of our cash flows and a discussion of our contractual obligations at December 27, 2024.

This section contains a discussion of the critical accounting estimates that we believe are important to our financial condition and results of operations and that require judgment and estimates on the part of management in their application. In addition, all of our significant accounting policies, including critical accounting policies, are summarized in Note 1, “Organization and Basis of Presentation,” in the Notes to Condensed Combined Financial Statements and Combined Financial Statements set forth in this prospectus.

Overview

The Separation

On October 30, 2023, WDC announced its intention to separate its Flash Business from its HDD Business. WDC determined to implement this separation through the spin-off of WDC’s Flash Business to its stockholders. Sandisk was formed to hold WDC’s Flash Business. Following the separation, we hold the assets and liabilities of WDC related to its Flash Business, subject to certain limited exceptions. After the separation, WDC continues to hold its HDD Business.

On January 25, 2025, the WDC Board of Directors approved the distribution of 80.1% of Sandisk’s issued and outstanding shares of common stock held by WDC to WDC stockholders on the basis of one share of our common stock for every three shares of WDC common stock held as of 1:00 p.m. Pacific time on February 12, 2025, the record date for the distribution, subject to certain conditions.

On February 21, 2025, the distribution was effected and the separation became effective as of 11:59 p.m. Pacific time. To effect the separation, WDC undertook a series of internal restructuring transactions to separate the assets, liabilities and certain legal entities of WDC associated with the Flash Business to us, in exchange for a cash payment of approximately $1.5 billion by us to WDC with a portion of the net proceeds of a term loan facility described below under “Financing Activities.” In conjunction with the separation, 116,035,464 shares of our common stock were distributed to WDC stockholders, as described below. Additionally, WDC retained 28,827,787 shares of our common stock representing its 19.9% retained interest. “Regular-way” trading of our common stock began with the opening of the Nasdaq on February 24, 2025, under the ticker symbol “SNDK.” Our common stock has a par value of $0.01 per share.

Following the distribution, our stockholders (other than WDC) own directly 80.1% of the outstanding shares of our common stock and WDC retained 19.9% of the outstanding shares of our common stock. WDC (the selling stockholder named herein) intends to dispose of all of our common stock that it retains through one or more subsequent exchanges of our common stock for WDC debt held by WDC creditors and/or through distributions of our common stock to WDC stockholders as dividends or in exchange for outstanding shares of WDC common stock, in each case during the 12-month period following the distribution. We are registering on a registration statement on Form S-1, of which this prospectus forms a part, the shares retained by WDC under the terms of a stockholder’s and registration rights agreement between us and the selling stockholder.

For purposes of the following sections of the MD&A, we use the terms “Sandisk Corporation,” “we,” “us,” and “our,” when referring to periods prior to the distribution, to refer to the Flash Business.

Our Business

Sandisk is a leading developer, manufacturer and provider of data storage devices and solutions based on NAND flash technology. With a differentiated innovation engine driving advancements in storage and semiconductor technologies, our broad and ever-expanding portfolio delivers powerful flash storage solutions for everyone from students, gamers and home offices, to the largest enterprises and public clouds to capture, preserve, access and transform an ever-increasing diversity of data. Our solutions include a broad range of solid-state drives (“SSD”), embedded products, removable cards, universal serial bus drives and wafers and components. Our broad portfolio of technology and products addresses multiple end markets of “Cloud,” “Client,” and “Consumer.”

##### Table of Contents

Through the Client end market, we provide our original equipment manufacturer (“OEM”) and channel customers a broad array of high-performance flash solutions across personal computer, mobile, gaming, automotive, virtual reality headsets, at-home entertainment and industrial spaces. The Consumer end market is highlighted by our broad range of retail and other end-user products, which capitalizes on the strength of our product brand recognition and vast points of presence around the world. Cloud is comprised primarily of products for public or private cloud environments and end customers.

Our fiscal year ends on the Friday nearest to June 30 and typically consists of 52 weeks. Approximately every five to six years, we report a 53-week fiscal year to align the fiscal year with the foregoing policy. Fiscal year 2025, which will end on June 27, 2025, and fiscal year 2024, which ended on June 28, 2024, are each comprised 52 weeks, with all quarters presented consisting of 13 weeks.

Sale-Leaseback

In September 2023, WDC completed a sale and leaseback of its facility in Milpitas, California, and received net proceeds of $191 million in cash. A substantial majority of these assets are associated with Sandisk and included in our Combined Balance Sheet as of June 28, 2024. As a result, $134 million of the net proceeds from the sale-leaseback transaction has been allocated to us on a relative square footage basis. The property is being leased back at a total annual rate of $16 million for the first year, increasing by 3% per year thereafter through January 1, 2039. The lease includes three five-year renewal options and one four-year renewal option for the ability to extend through December 2057. This facility is utilized in Sandisk’s operations, and a portion of the total annual lease expense will be allocated to Sandisk in future periods based on the continued usage of the facility.

SanDisk Semiconductor (Shanghai) Co. Ltd. (“SDSS”)

As discussed in Note 5, “Supplemental Financial Statement Data,” in the Notes to Condensed Combined Financial Statements, in March 2024, WDC entered into an agreement to sell 80% of the equity interest in SanDisk China Limited (“SanDisk China”) to JCET, a third-party contract manufacturing company. On September 28, 2024, the transaction closed. In connection with this transaction, WDC entered into a 5-year supply agreement with JCET to purchase wafers with a minimum annual commitment of $550 million.

As a result of this transaction, we expect to incur a modest reduction in annual operating expenses and a reduction in annual capital expenditures related to assembly testing of our products. We also expect that the transition to a contract manufacturing model through SDSS will result in a small increase in our annual cost of revenue for our products.

Financing Activities

We received financing from certain of WDC’s subsidiaries in the form of borrowings under revolving credit agreements and promissory notes to fund activities primarily related to Flash Ventures. Additional information regarding our outstanding notes due to (from) Parent is included in Note 9, “Related Parties and Related Commitments and Contingencies” of the Notes to the Condensed Combined Financial Statements.

On February 21, 2025, we entered into the Loan Agreement. The Loan Agreement comprises the Facilities. On February 21, 2025, we borrowed $2.0 billion under the Term Loan Facility. For a more detailed description of the Facilities, see the section of this prospectus entitled “Description of Material Indebtedness” on page 150.

Operational Update

Macroeconomic factors such as inflation, changes in interest rates and recession concerns softened demand for our products during 2023 and the first half of 2024. As a result, we and our industry experienced a supply-demand imbalance, which resulted in reduced shipments and negatively impacted pricing during those periods. To adapt to these conditions, since the beginning of 2023, we implemented measures to reduce operating expenses and proactively manage supply and inventory to align with demand and improve our capital efficiency while continuing

to deploy innovative products. These actions enabled us to scale back on capital expenditures, consolidate production lines and reduce production. During the first quarter of 2024, these actions resulted in incremental charges for employee termination, asset impairment and charges for unabsorbed manufacturing overhead costs due to the underutilization of facilities as we temporarily scaled back production.

We are now seeing an improvement in the supply and demand dynamic, leading to improved revenues. The increase in demand resulted in increased revenue and gross margin in the first six months of 2025 from the comparable period in the prior year. We anticipate that digital transformation, including the Artificial Intelligence (the “AI”) data-cycle, will continue to drive improved market conditions in the long-term for data storage. Leveraging our expertise and innovation in both areas, we believe we are well-positioned to capitalize on this improved market condition.

Subsequent to the completion of the separation, the Company identified potential impairment indicators related to the trading price of the Company’s common stock and a resulting market capitalization that was below its December 27, 2024 net book value. In accordance with Accounting Standards Codification No. 350, Intangibles - Goodwill and Other, the Company initiated a quantitative analysis of potential impairment of goodwill and long-lived assets. That analysis is ongoing, and the Company believes it is more likely than not that it will record an impairment charge in the three months ended March 28, 2025. See Note 5, Supplemental Financial Statement Data, for information about how goodwill is tested for impairment.

Additionally, the United States has recently announced changes to U.S. trade policy, including increasing tariffs on imports, in some cases significantly. These tariffs have the potential to raise the cost of our products sold in the U.S. and may adversely affect demand for our products in the U.S. We also cannot predict the potential responses to these actions or future trade policies and regulations in the U.S. and other countries, the terms of any trade arrangements that may be negotiated between the U.S. and other countries, the scope, amount, or duration of tariffs that may be imposed by any country, or the impact of these factors on our business, but each of these factors could increase the costs of our products and the materials and components used in our products, increase the prices of our products, and adversely affect demand for our products.

We will continue to actively monitor developments impacting our business and may take additional responsive actions that we determine to be in the best interest of our business and stakeholders.

Net Revenue

Six months ended December 27, 2024 compared with six months ended December 29, 2023

Net revenue increased 18% in the six months ended December 27, 2024 from the comparable period in the prior year, primarily due to a 26% increase in average selling price (“ASP”) per gigabyte attributed to improved pricing as the supply-demand balance improved, partially offset by a 7% decrease in exabytes sold driven by softer demand in the Client and Consumer end markets.

Cloud revenue increased 848% in the six months ended December 27, 2024 from the comparable period in the prior year, primarily due to a 571% increase in exabytes sold and a 31% increase in ASP per gigabyte due to the supply-demand balance recovery and improved pricing.

Client revenue increased 7% in the six months ended December 27, 2024 from the comparable period in the prior year, primarily due to a 37% increase in ASP per gigabyte due to improved pricing as the supply-demand balance improved, partially offset by a 22% decrease in exabytes sold primarily due to a drop in demand.

63

##### Table of Contents

Consumer revenue decreased 5% in the six months ended December 27, 2024 from the comparable period in the prior year, primarily due to an 8% decrease in exabytes sold due to softer demand, partially offset by a 2% increase in ASP per gigabyte.

The changes in net revenue by geography in the six months ended December 27, 2024 from the comparable period in the prior year primarily reflected higher revenue in the Americas region from Cloud customers.

Consistent with standard industry practice, we offer sales incentive and marketing programs that provide customers with price protection and other incentives or reimbursements that are recorded as a reduction to gross revenue. For the six months ended December 27, 2024 and December 29, 2023, these programs represented 19% and 23%, respectively, of gross revenues. The amounts attributed to our sales incentive and marketing programs generally vary according to several factors, including industry conditions, list pricing strategies, seasonal demand, competitor actions, channel mix and overall availability of products. Changes in future customer demand and market conditions may require us to adjust our incentive programs as a percentage of gross revenue.

Gross Profit and Gross Margin

Six months ended December 27, 2024 compared with six months ended December 29, 2023

Gross profit increased $1,359 million for the six months ended December 27, 2024 from the comparable period in the prior year, primarily due to improved pricing, favorable product mix, and prior year charges for unabsorbed manufacturing overhead costs as a result of the reduced utilization of our manufacturing capacity of $249 million, which were not incurred in the current period.

Gross profit margin increased by 36% for the six months ended December 27, 2024 from the comparable period in the prior year, primarily due to improved pricing, favorable product mix, and a prior year charge for unabsorbed manufacturing overhead costs as a result of the reduced utilization of our manufacturing capacity representing 8% which were not incurred in the current period.

Operating Expenses

Six months ended December 27, 2024 compared with six months ended December 29, 2023

Research and development (“R&D”) expense increased by $76 million in the six months ended December 27, 2024 from the comparable period in the prior year, primarily due to a $42 million increase in compensation and benefits due to higher variable compensation and increased headcount, a $16 million increase in material purchases, and increases in spending for R&D projects as we continue to invest in innovation.

Selling, general and administrative expense increased by $41 million in the six months ended December 27, 2024 from the comparable period in the prior year, primarily due to a $27 million increase in compensation and benefits due to higher variable compensation and increased headcount and a $13 million increase in materials purchases.

Business separation costs were $41 million for the six months ended December 27, 2024, primarily reflecting outside service fees to support the separation of Sandisk from WDC.

Employee termination and other charges increased $51 million in the six months ended December 27, 2024 from the comparable period in the prior year, primarily due to a $60 million gain on the sale-leaseback of a facility in the prior period. For additional information regarding employee termination and other charges, see Note 13, Employee Termination and Other Charges of the Notes to Condensed Combined Financial Statements.

Gain on business divestiture was $34 million for the six months ended December 27, 2024, primarily reflecting the gain resulting from the sale of 80.1% interest in SanDisk China to JCET on September 28, 2024. For additional information regarding the sale, see Note 5, “Supplemental Financial Statement Data,” in the Notes to Condensed Combined Financial Statements.

Interest and Other Income (Expense), net

Six months ended December 27, 2024 compared with six months ended December 29, 2023

Interest and other expense, net increased $24 million in the six months ended December 27, 2024 from the comparable period in the prior year, primarily due to a $25 million increase in foreign exchange losses and a $20 million increase in losses on our equity investments, partially offset by a $16 million decrease in interest expense on borrowings due to WDC and $4 million in interest income arising from the accretion of the present value discount on the outstanding SDSS consideration receivable.

Income Tax Expense

The Tax Cuts and Jobs Act (the “2017 Act”) requires the Company to capitalize and amortize R&D expenses rather than expensing them in the year incurred. The tax effects related to the capitalization of R&D expenses are included in our effective tax rate for the three and six months ended December 27, 2024 and December 29, 2023. The tax effects related to the capitalization of R&D expenses had a material impact on our effective tax rate for the three and six months ended December 27, 2024 but did not have a material impact on the effective tax rate for the three and six months ended December 29, 2023.

On August 16, 2022, President Biden signed into law the Inflation Reduction Act of 2022, which contained significant changes to laws related to tax, climate, energy, and health care. The tax measures include, among other things, a corporate alternative minimum tax (“CAMT”) of 15% on corporations with three-year average annual adjusted financial statement income (“AFSI”) exceeding $1.0 billion. The corporate alternative minimum tax was effective for us beginning with fiscal year 2024. We do not expect to be subject to the CAMT of 15% for fiscal year 2025 as our average annual AFSI did not exceed $1.0 billion for the preceding three-year period.

On December 20, 2021, the Organization for Economic Co-operation and Development G20 Inclusive Framework on Base Erosion and Profit Shifting released Model Global Anti-Base Erosion rules under Pillar Two (“Pillar Two”). Several non-U.S. jurisdictions have either enacted legislation or announced their intention to enact future legislation to adopt certain or all components of the Pillar Two, some of which are effective for the Company in fiscal year 2025. For fiscal year 2025, we currently expect to be able to meet certain transitional safe harbors and do not expect any material Pillar Two taxes. As more jurisdictions adopt this legislation in fiscal year 2026, there may be material increases in our future tax obligations in certain jurisdictions.

The following table presents the Company’s Income tax expense and effective tax rate:

|  | December 27, 2024 |  |  | December 29, 2023 |
|  | (in millions) |
Income before taxes |  | $ | 440 |  |  | $ | (754 | )
Income tax expense |  | $ | 125 |  |  | $ | 65 |
Effective tax rate |  |  | 28 | % |  |  | (9 | )%

The relative mix of earnings and losses by jurisdiction, the deduction for foreign-derived intangible income, credits and tax holidays in Malaysia that have or will expire at various dates during years 2025 through 2031 resulted in decreases to the effective tax rate below the U.S. statutory rate for the three and six months ended December 27, 2024. However, the tax effects of the mandatory capitalization of R&D expenses offset these decreases, resulting in the effective tax rate being closer to the U.S. Federal statutory rate for the six months ended December 27, 2024.

For additional information regarding income tax expense, see Note 12, “Income Tax Expense,” in the Notes to the Condensed Combined Financial Statements.

Net Revenue

Year ended June 28, 2024 compared with year ended June 30, 2023

Net revenue increased 9% in 2024 compared to 2023, primarily driven by a 21% increase in exabytes sold, partially offset by an 8% decline in ASP per gigabyte. The increase in exabytes sold was primarily driven by improved demand from our OEM customers in our Client end market, and higher shipments of SSDs to our customers in our Consumer end market, partially offset by lower shipments in our Cloud end market. The decrease in ASP per gigabyte was primarily driven by the supply-demand imbalance in the first half of the year, prior to the recent improvement in supply-demand conditions as described above.

The 35% decrease in Cloud revenue in 2024 compared to 2023, is primarily due to a 31% decrease in exabytes shipments and a 5% decrease in ASP per gigabyte. The decline in ASP per gigabyte was primarily attributable to the factors described above. In Client, the 12% increase in revenue in 2024 compared to 2023 reflects a 24% increase in exabyte shipments, partially offset by a 5% decrease in ASP per gigabyte. In Consumer, the 16% increase in revenues in 2024 compared to 2023 was due to a 32% increase in exabytes sold, partially offset by a 10% decrease in ASP per gigabyte.

The changes in net revenue by geography in 2024, compared to 2023, primarily reflected larger growth in Asia from OEMs in this region as their production levels increased as well as routine variations in the mix of business.

Year ended June 30, 2023 compared with year ended July 1, 2022

Net revenue decreased 38% in 2023 compared to 2022, substantially all driven by a decline in the ASP of 39% per gigabyte, primarily reflecting the macroeconomic pressures described in the “Operational Update” above. The decline in the ASP per gigabyte was due to the supply-demand imbalance described in the “Overview—Operational Update” section above as well as a shift in product mix.

The 60% decrease in Cloud revenue in 2023 compared to 2022, is primarily due to a 28% decrease in exabytes shipments and a 45% decrease in ASP per gigabyte. The decline in ASP per gigabyte was primarily attributable to the factors described in the “Overview—Operational Update” section above. In Client, the 40% decrease in revenue in 2023 compared to 2022 reflects a decline of 42% decrease in ASP per gigabyte, due to pricing pressure across flash products. In Consumer, the 21% decrease in revenues in 2023 compared to 2022 was due to approximately 30% decrease in ASP per gigabyte, partially offset by a 14% increase in exabytes sold.

The changes in net revenue by geography in 2023, compared to 2022, reflect a 40% decline in Asia from lower Client revenue from OEMs in this region as they reduced purchases to align with current market demand.

For 2024, 2023 and 2022, our top 10 customers accounted for 41%, 47% and 47%, respectively, of our net revenue. For 2024 no single customer accounted for more than 10% of our net revenue. For 2023 and 2022, one customer accounted for 15% and 11%, respectively, of our net revenue.

Consistent with standard industry practice, we have sales incentive and marketing programs that provide customers with price protection and other incentives or reimbursements that are recorded as a reduction to gross revenue. For 2024, 2023 and 2022, these programs represented 19%, 21% and 15%, respectively, of gross revenues. The amounts attributed to our sales incentive and marketing programs generally vary according to several factors, including industry conditions, list pricing strategies, seasonal demand, competitor actions, channel mix and overall availability of products. Changes in future customer demand and market conditions may require us to adjust our incentive programs as a percentage of gross revenue.

Gross Profit and Gross Margin

Year ended June 28, 2024 compared with year ended June 30, 2023

Gross profit increased $642 million, or 149%, in 2024 compared to 2023, largely due to higher revenue, cost reductions due to cost efficiencies achieved through improved manufacturing operations and cost-saving actions and a more favorable product mix. The increase also reflected charges of approximately $252 million for unabsorbed manufacturing overhead costs as a result of the increased utilization of our manufacturing capacity in 2024 as compared to $296 million of such costs in 2023, and a $54 million write-down of Flash inventory as a result of the decreases in market pricing in 2024 compared to charges of $108 million of such costs in 2023. Gross margin increased 9% over the prior year with approximately 2% of the increase due to the net charges noted above and the remainder driven by improving pricing, cost reduction initiatives and a favorable shift in product mix.

Year ended June 30, 2023 compared with year ended July 1, 2022

Gross profit decreased $2.8 billion, or 87%, in 2023 compared to 2022, which reflected the decrease in revenue described above as well as $296 million charges for unabsorbed manufacturing overhead costs as a result of the reduced utilization of our manufacturing capacity, and a $108 million write-down of certain flash inventory to the lower of cost or market value, partially offset by $207 million of charges related to a contamination event in the Flash Ventures’ fabrication facilities incurred in 2022, and a $64 million decrease in charges related to amortization expense on acquired intangible assets, some of which became fully amortized in 2023. Gross margin decreased 26% over 2022, with approximately 4% of the decline due to the net charges noted above and the remainder driven by the lower ASP per gigabyte.

Operating Expenses

Year ended June 28, 2024 compared with year ended June 30, 2023

Research and development expense decreased $106 million or 9% in 2024 compared to 2023, which reflects a decrease of $57 million in compensation and benefits due to reduced headcount, a decrease of $36 million in costs related to a reduction in our portion of development costs of the fabrication facilities of Flash Ventures, a decrease of $22 million in depreciation and amortization attributable to lower capital expenditures and a decrease of $6 million in outside services, which were partially offset by an increase of $15 million in material purchases.

Selling, general and administrative expense decreased $103 million or 18% in 2024 compared to 2023. This decrease was driven by a decrease of $133 million in intangible amortization expense and a decrease of $6 million in all other—miscellaneous costs, partially offset by an increase of $19 million in compensation and benefits due to an increase in variable compensation and an increase of $17 million in material purchases.

Employee termination, asset impairment and other decreased $109 million or 158% compared to 2023, due to a $60 million gain on the sale-leaseback of the Milpitas California facility and a $53 million decrease in employee termination costs as a result of fewer restructuring actions taken in the current period, partially offset by $4 million related to asset impairment caused by project cancellations. For additional information regarding employee termination, asset impairment and other charges, see Note 13, “Employee Termination, Asset Impairment and Other,” in the Notes to Combined Financial Statements.

Year ended June 30, 2023 compared with year ended July 1, 2022

Research and development expense decreased $195 million or 14% in 2023 compared to 2022, which reflects a decrease of $123 million in compensation and benefits due to lower variable compensation and a reduced headcount, a decrease of $25 million in materials cost related to product samples, as well as savings resulting from our actions to reduce expenses in the dynamic economic environment in 2023.

Selling, general and administrative expense decreased $108 million or 16% in 2023 compared to 2022, which reflects a decrease of $60 million in compensation and benefits due to lower variable compensation and a reduced headcount, a decrease of $23 million in materials cost related to product samples, a decrease of $22 million in intangible amortization expense due to certain intangible assets becoming fully amortized in 2023, as well as savings resulting from our actions to reduce expenses in the dynamic economic environment in 2023. The decrease was partially offset by a $20 million charges related to our strategic review.

Employee termination, asset impairment and other increased $53 million or 331% compared to 2022, due to an increase of $46 million in restructuring actions taken to adjust our cost structure to align with the current demand environment and a $9 million gain on sale of a business in 2022, partially offset by a decrease of $2 million in loss on disposal of assets. For additional information regarding employee termination, asset impairment and other charges, see Note 13, “Employee Termination, Asset Impairment and Other,” in the Notes to Combined Financial Statements.

Interest and Other Income (Expense), net

Year ended June 28, 2024 compared with year ended June 30, 2023

The total interest and other income (expense), net decreased $68 million or 206% in 2024 compared to 2023. This decline was primarily driven by a $48 million decrease in equity earnings from Flash Ventures, coupled with a decrease of $9 million in interest income and a corresponding increase of $9 million in interest expense.

Year ended June 30, 2023 compared with year ended July 1, 2022

The total interest and other income (expense), net decrease of $1 million or 3% in 2023 compared to 2022, which was primarily driven by an increase of $16 million in interest expense, partially offset by an increase of $15 million in interest income.

Income Tax Expense

The 2017 Act includes a broad range of tax reform proposals affecting businesses. WDC completed its accounting for the tax effects of the enactment of the 2017 Act during the second quarter of 2019. However, the U.S. Treasury and the IRS have issued tax guidance on certain provisions of the 2017 Act since the enactment date, and Sandisk anticipates the issuance of additional regulatory and interpretive guidance. WDC applied a reasonable interpretation of the 2017 Act along with the then-available guidance in finalizing its accounting for the tax effects of the 2017 Act. Any additional regulatory or interpretive guidance would constitute new information, which may require further refinements to our estimates in future periods.

On August 16, 2022, President Biden signed into law the Inflation Reduction Act of 2022, which contained significant law changes related to tax, climate, energy and health care. The tax measures include, among other things, a corporate alternative minimum tax or CAMT, of 15% on corporations with three-year average annual adjusted financial statement income, or AFSI, exceeding $1.00 billion. We are not subject to the CAMT of 15% for fiscal year 2024 as our average annual AFSI did not exceed $1.00 billion for the preceding three-year period.

The following table sets forth income tax information from our Statement of Operations by dollar and effective tax rate:

|  | 2024 |  |  | 2023 |  |  | 2022 |
|  | (in millions, except percentages) |
Income (loss) before taxes |  | $ | (503 | ) |  | $ | (2,002 | ) |  | $ | 1,234 |
Income tax expense |  |  | 169 |  |  |  | 141 |  |  |  | 170 |
Effective tax rate |  |  | (34 | )% |  |  | (7 | )% |  |  | 14 | %

Beginning in 2023, the 2017 Act requires us to capitalize and amortize research and development expenses rather than expensing them in the year incurred. The tax effects related to the capitalization of research and development expenses are included in income tax expense but did not have a material impact on our effective tax rate.

The primary drivers of the difference between the effective tax rate for 2024 and the U.S. federal statutory rate of 21% are the relative mix of earnings and losses by jurisdiction, the deduction for foreign derived intangible income, credits and tax holidays in Malaysia that will expire at various dates during years 2028 through 2031.

The primary drivers of the difference between the effective tax rate for 2023 and 2022 and the U.S. federal statutory rate of 21% for both periods are the relative mix of earnings and losses by jurisdiction, the deduction for foreign derived intangible income, credits and tax holidays in Malaysia that will expire at various dates during years 2028 through 2031.

Our future effective tax rate is subject to future regulatory developments and changes in the mix of our U.S. earnings compared to foreign earnings. Our total tax expense in future years may also vary as a result of discrete items such as excess tax benefits or deficiencies.

On December 20, 2021, the OECD/G20 Inclusive Framework on Base Erosion and Profit Shifting released Model Global Anti-Base Erosion rules under Pillar Two (“Pillar Two Model Rules”). Several non-US jurisdictions have either enacted legislation or announced their intention to enact future legislation to adopt certain or all components of the Pillar Two Model Rules, which may be effective for us as early as 2025. When effective, this legislation could materially increase our tax obligations in certain jurisdictions. We continue to evaluate the tax impact of enacted and future legislation concerning the Pillar Two Model Rules in the non-US tax jurisdictions we operate in.

For additional information regarding income tax expense, see Note 12, “Income Tax Expense,” in the Notes to the Combined Financial Statements.

Quarterly Revenue Trends

For the quarters ended December 30, 2022, March 31, 2023, and June 30, 2023, there was a decline in revenue due to macroeconomic factors including inflation, higher interest rates and recession concerns, which softened demand for our products, leading to reduced shipments and pricing challenges. In contrast, the quarters ended September 29, 2023, December 29, 2023, March 29, 2024, June 28, 2024, September 27, 2024 and December 27, 2024, showed significant growth compared to the comparable quarters in the prior year, driven primarily by improved supply and demand dynamics and better pricing, which positively impacted our revenue.

Quarterly Operating Expense Trends

Research and Development. The fluctuations in research and development are largely a result of normal fluctuations in compensation and benefits, development costs and depreciation and amortization.

Selling, general and administrative. For the quarters ended September 30, 2022, through March 29, 2024, selling, general and administrative expenses trended downward primarily driven by reductions in intangible amortization expense, compensation and benefits and materials costs. The driver for the increase in selling, general and administrative expenses in the three months ended June 28, 2024, September 27, 2024, and December 27, 2024 was primarily higher variable compensation, increased headcount and increased legal fees.

Employee termination, asset impairment and other charges. For the quarter ended June 30, 2023, the increase in employee termination, asset impairment and other expenses was driven by increased restructuring initiatives to adjust our cost structure to align with the demand environment. The fluctuation in employee termination, asset impairment and other charges during the quarter ended September 29, 2023 was primarily driven by a $60 million gain on the sale-leaseback of our Milpitas, California facility.

Business separation costs. The charges related to business separation costs for the quarters ended September 29, 2023, December 29, 2023, March 29, 2024, June 28, 2024, September 27, 2024, and December 27, 2024, relate to outside service fees to support the separation of Sandisk from WDC.

Gain on business divestiture. The gain on business divestiture for the quarter ended December 27, 2024 relates to WDC’s sale of an 80.1% interest in SanDisk China Limited to JCET Management Co., Ltd.

Goodwill Impairment charges. For the quarters ended September 30, 2022, and December 30, 2022, we determined that the carrying value of our single reporting unit exceeded its fair value, resulting in the recognition of impairment charges of $522 million and $149 million, respectively.

Financial Condition, Liquidity and Capital Resources

The following table summarizes our statements of cash flows for the six months ended December 27, 2024, and December 29, 2023:

|  | December 27, 2024 |  |  | December 29, 2023 |

Effect of exchange rate changes on cash |  |  | (1 | ) |  |  | 1 |
Net increase (decrease) in cash and cash equivalents |  | $ | 476 |  |  | $ | 133 |

As noted previously, we have been scaling back on capital expenditures, consolidating production lines and reducing bit growth to align with market demand. We have access to our $1,500 million revolving credit facility and continue to be cautious in our capital investment and expect our cash capital expenditures in 2025 to be higher than in 2024 but remain below 2023 expenditures.

We believe our cash, and cash equivalents, as discussed in “Overview—Financing Activities” above, will be sufficient to meet our working capital needs for at least the next twelve months and for the foreseeable future thereafter, as we navigate the current market downturn before returning to profitable operations and positive cash flows when the market normalizes. We believe we can also access the various capital markets to further supplement our liquidity position if necessary.

A total of $692 million and $321 million, of our cash and cash equivalents were held outside of the U.S. as of December 27, 2024, and June 28, 2024, respectively. There are no material tax consequences that were not previously accrued for on the repatriation of this cash.

##### Table of Contents

Operating Activities

Net cash used in operating activities primarily consists of net income or loss, adjusted for non-cash charges, plus or minus changes in operating assets and liabilities. Net cash used as a result of changes in operating assets and liabilities was $487 million in the six months ended December 27, 2024, as compared to $449 million net cash provided in the six months ended December 29, 2023, reflecting an increase in the volume of our business, as discussed above.

Changes in our operating assets and liabilities are largely affected by our working capital requirements, which are dependent on the volume of our business and the effective management of our cash conversion cycle as well as timing of payments for taxes. Our cash conversion cycle measures how quickly we can convert our products into cash through sales. The cash conversion cycles were as follows:

|  | December 27, 2024 |  |  | December 29, 2023 |
|  | (in days) |
Days sales outstanding |  |  | 44 |  |  |  | 37 |
Days in inventory |  |  | 156 |  |  |  | 98 |
Days payables outstanding |  |  | (49 | ) |  |  | (39 | )
Cash Conversion cycle |  |  | 151 |  |  |  | 96 |

Changes in days sales outstanding, or “DSO,” are generally due to the timing of shipments. Changes in days in inventory, or “DIO,” are generally related to the timing of inventory builds. Changes in days payables outstanding, or “DPO,” are generally related to production volume and the timing of purchases during the period. From time to time, we modify the timing of payments to our vendors. We make modifications primarily to manage our vendor relationships and to manage our cash flows, including our cash balances. Generally, we make the payment term modifications through negotiations with our vendors or by granting to, or receiving from, our vendors’ payment term accommodations.

For the three months ended December 27, 2024, DSO increased by seven days over the three months ended December 29, 2023, reflecting lower accounts receivable factoring and the timing of shipments and customer collections. During the three months ended December 27, 2024, DIO increased by 58 days over the three months ended December 29, 2023, primarily reflecting lower consumption of inventory in the current period. DPO increased by 10 days over the comparable period in the prior year primarily due to routine variations in the timing of purchases and payments during the period.

Investing Activities

Net cash provided by investing activities in the six months ended December 27, 2024 primarily consisted of $191 million in proceeds related to the sale of an 80% equity interest in SDSS, and $92 million of net notes receivable and distribution proceeds from activity related to Flash Ventures, partially offset by $115 million in purchases of property, plant and equipment. Net cash provided by investing activities in the six months ended December 29, 2023 primarily consisted of $134 million proceeds from the sale of property, plant and equipment, which includes the proceeds from the sale-leaseback of our Milpitas, California facility and $79 million in net proceeds from activity related to Flash Ventures, partially offset by $99 million in purchases of property, plant and equipment.

Financing Activities

Net cash provided by financing activities in the six months ended December 27, 2024 primarily consisted of $550 million in proceeds from notes due to WDC and $101 million in proceeds from principal repayments on notes due from WDC, partially offset by $307 million in repayments of notes due to WDC and transferred to

##### Table of Contents

WDC. Net cash provided by financing activities in the six months ended December 29, 2023 primarily consisted of $274 million transferred from WDC, partially offset by $14 million in net repayments on notes due to WDC.

The following table summarizes our statements of cash flows as of 2024, 2023 and 2022:

|  | 2024 |  |  | 2023 |  |  | 2022 |

As noted previously, we have been scaling back on capital expenditures, consolidating production lines and reducing bit growth to align with market demand. We reduced our portion of the capital expenditures by Flash Ventures for its operations to approximately $773 million in 2024 from approximately $1.4 billion in 2023. After consideration of the Flash Ventures’ lease financing of its capital expenditures and net operating cash flow, we reduced our net cash used for our purchases of property, plant and equipment and net activity in notes receivable relating to Flash Ventures $210 million in 2024, as compared to cash used of $205 million in 2023.

A total of $321 million, $286 million and $332 million of our cash and cash equivalents were held outside of the U.S. as of June 28, 2024, June 30, 2023, and July 1, 2022, respectively. There are no material tax consequences that were not previously accrued for on the repatriation of this cash.

Operating Activities

Net cash provided by or used in operating activities primarily consists of net income or loss, adjusted for non-cash charges, plus or minus changes in operating assets and liabilities. Net cash used as a result of changes in operating assets and liabilities was $86 million for 2024, as compared to $197 million net cash provided in 2023, which reflects the reduction in the volume of our business. Comparably, the net cash provided by changes in operating assets and liabilities was $197 million for 2023, compared to $600 million net cash used in 2022, which reflects the increase in the volume of our business. Changes in our operating assets and liabilities are largely affected by our working capital requirements, which are dependent on the effective management of our cash conversion cycle as well as timing of payments for taxes. Our cash conversion cycle measures how quickly we can convert our products into cash through sales. At the end of the respective fourth quarters, the cash conversion cycles were as follows:

|  | 2024 |  |  | 2023 |  |  | 2022 |
|  | (in days) |
Days sales outstanding |  |  | 56 |  |  |  | 35 |  |  |  | 49 |
Days in inventory |  |  | 103 |  |  |  | 134 |  |  |  | 117 |
Days payables outstanding |  |  | (35 | ) |  |  | (37 | ) |  |  | (46 | )
Cash conversion cycle |  |  | 124 |  |  |  | 132 |  |  |  | 120 |

Changes in days sales outstanding, or DSO, are generally due to the timing of shipments. Changes in days in inventory, or DIO, are generally related to the timing of inventory builds. Changes in days payables outstanding, or DPO, are generally related to production volume and the timing of purchases during the period. From time to time, we modify the timing of payments to our vendors. We make modifications primarily to manage our vendor relationships and to manage our cash flows, including our cash balances. Generally, we make the payment term modifications through negotiations with our vendors or by granting to, or receiving from, our vendors’ payment term accommodations.

##### Table of Contents

In 2024, DSO increased by 21 days over 2023, reflecting lower accounts receivable factoring and the timing of shipments and customer collections. In 2024, DIO decreased by 31 days over 2023, primarily reflecting an increase in products shipped. In 2024, DPO decreased by 2 days over 2023, primarily due to reductions in production volume and capital expenditures as well as routine variations in the timing of purchases and payments during the period.

In 2023, DSO decreased by 14 days over 2022, reflecting the increase in accounts receivable factoring. In 2023, DIO increased by 17 days over 2022, primarily reflecting a decline in products shipped in light of the market environment. In 2023, DPO decreased by 9 days over 2022, primarily due to reductions in production volume and capital expenditures as well as routine variations in the timing of purchases and payments during the period.

Investing Activities

Net cash provided by investing activities in 2024 primarily consisted of $239 million of net notes receivable proceeds from (issuance to) Flash Ventures and $137 million of proceeds from the sale of property, plant and equipment, partially offset by $166 million in purchases of property, plant and equipment. Net cash used in investing activities in 2023 primarily consisted of $219 million in purchases of property, plant and equipment, partially offset by a $14 million net decrease in notes receivable issuance to Flash Ventures and $16 million in net proceeds from the sale of strategic investments and other. Net cash used in investing activities in 2022 primarily consisted of $410 million in purchases of property, plant and equipment, and a $91 million net increase in notes receivable issuances to Flash Ventures, offset by $25 million in proceeds from the disposition of business, $3 million in net proceeds from the sale of strategic investments and other, and $1 million in proceeds from the sale of property, plant and equipment.

Financing Activities

Net cash provided by financing activities in 2024 primarily consisted of $394 million transferred from Parent and $14 million in proceeds from notes due from Parent, offset by $170 million in origination of notes due from Parent and $102 million in net repayments on notes due to Parent.

Net cash provided in financing activities in 2023 primarily consisted of $676 million transferred from Parent and $216 million in proceeds from notes due from Parent, offset by $32 million in net repayments on notes due to Parent.

Net cash used in financing activities in 2022 primarily consisted of $933 million transferred to Parent, offset by $307 million in proceeds from notes due to Parent and $199 million in net proceeds from notes due from Parent.

Off-Balance Sheet Arrangements

Other than the commitments related to Flash Ventures incurred in the normal course of business and certain indemnification provisions (see “Short- and Long-term Liquidity—Purchase Obligations and Other Commitments” below), we do not have any other material off-balance sheet financing arrangements or liabilities, guarantee contracts, retained or contingent interests in transferred assets, or any other obligation arising out of a material variable interest in an unconsolidated entity. We do not have any majority-owned subsidiaries that are not included in the Condensed Combined Financial Statements and Combined Financial Statements. Additionally, with the exception of Flash Ventures, joint venture with Unisplendour Corporation Limited and Unissoft (Wuxi) Group Co. Ltd., and the SDSS Venture, we do not have an interest in, or relationships with, any variable interest entities. For additional information regarding our off-balance sheet arrangements, see Note 9, “Related Parties and Related Commitments and Contingencies,” of the Notes to the Condensed Combined Financial Statements and Notes to the Combined Financial Statements.

(1) | Includes reimbursement for depreciation and lease payments on owned and committed equipment, funding commitments for loans and equity investments and payments for other committed expenses, including research and development and building depreciation. Funding commitments assume no additional operating lease guarantees. Additional operating lease guarantees can reduce funding commitments.

Flash Ventures

Flash Ventures sells to, and leases back from, a consortium of financial institutions a portion of its tools and has entered into equipment lease agreements, of which we guarantee half or all of the outstanding obligations under each lease agreement. The leases are subject to customary covenants and cancellation events that relate to Flash Ventures and each of the guarantors. The occurrence of a cancellation event could result in an acceleration of the lease obligations and a call on our guarantees. As of December 27, 2024, and as of June 28, 2024, we were in compliance with all covenants under these Japanese lease facilities. See Note 9, “Related Parties and Related Commitments and Contingencies,” of the Notes to the Condensed Combined Financial Statements and Notes to the Combined Financial Statements.

Purchase Obligations and Other Commitments

In the normal course of business, we enter into purchase orders with suppliers for the purchase of components used to manufacture our products. These purchase orders generally cover forecasted component supplies needed for production during the next quarter, are recorded as a liability upon receipt of the components, and generally may be changed or canceled at any time prior to shipment of the components. We also enter into long-term agreements with suppliers that contain fixed future commitments, which are contingent on certain conditions such as performance, quality and technology of the vendor’s components. These arrangements are included under “Purchase obligations and other commitments” in the table above.

Unrecognized Tax Benefits

As of December 27, 2024, the liability for unrecognized tax benefits (excluding accrued interest and penalties) was approximately $60 million. Accrued interest and penalties related to unrecognized tax benefits as of December 27, 2024 was approximately $6 million. Of these amounts, approximately $66 million could result in potential cash payments.

Foreign Exchange Contracts

We purchase foreign exchange contracts to hedge the impact of foreign currency fluctuations on certain underlying assets, liabilities and commitments for operating expenses and product costs denominated in foreign currencies. For a description of our current foreign exchange contract commitments, Note 7, “Derivative Instruments and Hedging Activities,” of the Notes to the Condensed Combined Financial Statements and Notes to the Combined Financial Statements.

Indemnifications

In the ordinary course of business, we may provide indemnifications of varying scope and terms to customers, vendors, lessors, business partners and other parties with respect to certain matters, including, but not limited to, losses arising out of our breach of agreements, products or services to be provided by us, environmental compliance, or intellectual property infringement claims made by third parties. In addition, we have entered into indemnification agreements with our directors and certain of our officers that will require us, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors or officers. We maintain director and officer insurance, which may cover certain liabilities arising from our obligation to indemnify our directors and officers in certain circumstances.

It is not possible to determine the maximum potential amount under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. Such indemnification agreements may not be subject to maximum loss clauses. Historically, we have not incurred material costs as a result of obligations under these agreements.

Critical accounting estimates

We have prepared the accompanying unaudited Condensed Combined Financial Statements and audited Combined Financial Statements in accordance with GAAP. The preparation of the financial statements requires the use of judgments and estimates that affect the reported amounts of revenues, expenses, assets, liabilities and WDC net investment. We have adopted accounting policies and practices that are generally accepted in the industry in which we operate. If these estimates differ significantly from actual results, the impact to the unaudited Condensed Combined Financial Statements and audited Combined Financial Statements may be material.

Revenue

We provide distributors and retailers (collectively referred to as “resellers”) with limited price protection for inventories held by resellers at the time of published list price reductions. We also provide resellers and OEMs with other sales incentive programs. Sandisk records estimated variable consideration related to these items as a reduction to revenue at the time of revenue recognition. We use judgment in our assessment of variable consideration in contracts to be included in the transaction price. We use the expected value method to arrive at the amount of variable consideration. Sandisk constrains variable consideration until the likelihood of a significant revenue reversal is not probable and believes that the expected value method is the appropriate estimate of the amount of variable consideration based on the fact that we have a large number of contracts with similar characteristics.

For sales to OEMs, Sandisk’s methodology for estimating variable consideration is based on the amount of consideration expected to be earned based on the OEMs’ volume of purchases from Sandisk or other agreed-upon sales incentive programs. For sales to resellers, the methodology for estimating variable consideration is based on several factors, including historical pricing information, current pricing trends and channel inventory levels. Estimating the impact of these factors requires significant judgment and differences between the estimated and actual amounts of variable consideration can be significant.

Inventories

We value inventories at the lower of cost or net realizable value, or “NRV,” with cost determined on a first-in, first-out basis. We record inventory write-downs of our inventory to lower of cost or net realizable value or for obsolete or excess inventory based on assumptions, which requires significant judgment. The determination of NRV involves estimating the average selling prices less any selling expenses of inventory based on market conditions and customer demand. To estimate the average selling prices and selling expenses of inventory, we review historical sales, future demand, economic conditions, contract prices and other information.

We periodically perform an excess and obsolete analysis of our inventory based on assumptions, which includes changes in business and economic conditions, changes in technology and projected demand of our products. If in any period we anticipate a change in those assumptions to be less favorable than our previous estimates, additional inventory write-downs may be required and could materially and negatively impact our gross margin. If in any period, we can sell inventories that had been written down to a level below the realized selling price in the previous period, higher gross profit would be recognized in that period. Although adjustments to these reserves have typically been immaterial, in fiscal year 2024, we recorded a charge to cost of revenue of $95 million, primarily to reduce component inventory to NRV as a result of a sudden change in demand for certain products.

Income Taxes

Income taxes are calculated as if Sandisk files tax returns separate from WDC. We account for income taxes under the asset and liability method, which provides that deferred tax assets and liabilities be recognized for temporary differences between the financial reporting basis and the tax basis of our assets and liabilities and expected benefits of utilizing net operating loss, “or NOL,” and tax credit carryforwards. We record a valuation allowance when it is more likely than not that the deferred tax assets will not be realized. Each quarter, we evaluate the need for a valuation allowance for our deferred tax assets and we adjust the valuation allowance so that we record net deferred tax assets only to the extent that we conclude it is more likely than not that these deferred tax assets will be realized. The assessment of valuation allowances against our deferred tax assets requires estimations and significant judgment. We continue to assess and adjust valuation allowances based on operating results and market conditions. We account for interest and penalties related to income taxes as a component of the provision for income taxes.

We recognize liabilities for uncertain tax positions based on a two-step process. To the extent a tax position does not meet a more-likely-than-not level of certainty, no benefit is recognized in the financial statements. If a position meets the more-likely-than-not level of certainty, it is recognized in the financial statements at the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. Interest and penalties related to unrecognized tax benefits are recognized on liabilities recorded for uncertain tax positions and are recorded in our provision for income taxes. The actual liability for unrealized tax benefits in any such contingency may be materially different from our estimates, which could result in the need to record additional liabilities for unrecognized tax benefits or potentially adjust previously recorded liabilities for unrealized tax benefits and materially affect our operating results.

Goodwill

Goodwill is not amortized. Instead, it is tested for impairment on an annual basis or more frequently if events or changes in circumstances indicate that goodwill may be impaired. Sandisk performs an annual impairment test as of the beginning of its fourth quarter or sooner if an indicator of impairment exists. We use qualitative factors to determine whether goodwill is more likely than not impaired and whether a quantitative test for impairment is considered necessary. If we conclude from the qualitative assessment that goodwill is more likely than not impaired, we are required to perform a quantitative assessment to determine the amount of impairment. We are required to use judgment when applying the goodwill impairment test, including in the identification of our

81

##### Table of Contents

reporting units. In addition, the estimates used to determine the fair value of each of our reporting unit may change based on results of operations, macroeconomic conditions or other factors. Changes in these estimates could materially affect Sandisk’s assessment of the fair value and goodwill impairment, which could result in a material charge and adversely affect our results of operations. We have not identified any impairment indicators for our reporting unit as of December 27, 2024, or as of June 28, 2024. We recorded goodwill impairment charges of $671 million for 2023 and recorded no goodwill impairment charges for 2022.

Subsequent to the completion of the separation, the Company identified potential impairment indicators related to the trading price of the Company’s common stock and a resulting market capitalization that was below its December 27, 2024 net book value. In accordance with Accounting Standards Codification No. 350, Intangibles - Goodwill and Other, the Company initiated a quantitative analysis of potential impairment of goodwill and long-lived assets. That analysis is ongoing, and the Company believes it is more likely than not that it will record an impairment charge in the three months ended March 28, 2025. See Note 5, Supplemental Financial Statement Data, for information about how goodwill is tested for impairment.

Quantitative and Qualitative Disclosures about Market Risk

Foreign Currency Risk

Although the majority of our transactions are in U.S. dollars, some transactions are based in various foreign currencies. We purchase short-term foreign exchange contracts to hedge the impact of foreign currency exchange fluctuations on certain underlying assets, liabilities and commitments for product costs and operating expenses denominated in foreign currencies. The purpose of entering into these hedge transactions is to minimize the impact of foreign currency fluctuations on our results of operations. Substantially all of the contract maturity dates do not exceed 12 months. We do not purchase foreign exchange contracts for speculative or trading purposes.

We have performed sensitivity analyses as of December 27, 2024, using a modeling technique that measures the change in the fair values arising from a hypothetical 10% adverse movement in the levels of foreign currency exchange rates relative to the U.S. dollar, with all other variables held constant. The analyses cover all of our foreign currency derivative contracts used to offset the underlying exposures. The foreign currency exchange rates used in performing the sensitivity analyses were based on market rates in effect at December 27, 2024. The sensitivity analyses indicated that a hypothetical 10% adverse movement in foreign currency exchange rates relative to the U.S. dollar would result in a foreign exchange fair value loss of $165 million at December 27, 2024.

Notwithstanding our efforts to mitigate some foreign exchange risks, we do not hedge all of our foreign currency exposures, and there can be no assurance that our mitigating activities related to the exposures that we do hedge will adequately protect us against risks associated with foreign currency fluctuations.

Interest Rate Risk

On February 21, 2025, we incurred variable rate debt in the principal amount of $2.0 billion under the Term Loan Facility. For additional information regarding the Term Loan Facility, see the section entitled “Description of Material Indebtedness.” As of March 28, 2025, the outstanding balance under the Term Loan Facility was $2.0 billion and a one percent increase in the variable rate of interest would increase annual interest expense by $20 million.

Research and Development

We devote substantial resources to the development of new products and the improvement of existing products. We focus our engineering efforts on optimizing our product design and manufacturing processes to bring our products to market in a cost-effective and timely manner. For a discussion of associated risks, see the section entitled “Risk Factors” beginning on page 13 of this prospectus.

Patents, Licenses and Proprietary Information

We rely on a combination of patents, trademarks, copyright and trade secret laws, confidentiality procedures and licensing arrangements to protect our intellectual property rights.

We have approximately 7,900 granted patents and approximately 2,800 pending patent applications worldwide. We continually seek additional United States (“U.S.”) and international patents on our technology. We believe that, although our active patents and patent applications have considerable value, the successful manufacturing and marketing of our products also depends upon the technical and managerial competence of our staff. Accordingly, the patents held and applied for cannot alone ensure our future success.

In addition to patent protection of certain intellectual property rights, we consider elements of our product designs and processes to be proprietary and confidential. We believe that our non-patented IP, particularly some of our process technology, is an important factor in our success. We rely upon non-disclosure agreements,

85

##### Table of Contents

contractual provisions and a system of internal safeguards to protect our proprietary information. Despite these safeguards, there is a risk that competitors may obtain and use such information. The laws of foreign jurisdictions in which we conduct business may provide less protection for confidential information than the laws of the U.S.

We rely on certain technology that we license from other parties to manufacture and sell our products. We believe that we have adequate cross-licenses and other agreements in place in addition to our own intellectual property portfolio to compete successfully in the storage industry. For a discussion of associated risks, see the section entitled “Risk Factors” beginning on page 13 of this prospectus.

Manufacturing

We believe that we have significant know-how, unique product manufacturing processes, test and tooling, execution skills, human resources and training to continue to be successful and to adjust our manufacturing operations as necessary. We strive to maintain manufacturing flexibility, high manufacturing yields, reliable products and high-quality components. The critical elements of our production are high volume and utilization, low-cost assembly and testing, strict adherence to quality metrics and maintaining close relationships with our strategic component suppliers to access best-in-class technology and manufacturing capacity. We continually monitor our manufacturing capabilities to respond to the changing requirements of our customers and maintain our competitiveness and position as a data technology leader.

Flash manufacturing requires complex processes involving the production and assembly of precision components with narrow tolerances and rigorous testing. The manufacturing processes involve a number of steps that are dependent on each other and occur in “clean room” environments that demand skill in process engineering and efficient space utilization to control the operating costs of these manufacturing environments. We continually evaluate our manufacturing processes in an effort to increase productivity, sustain and improve quality and decrease manufacturing costs. We continually evaluate which steps in the manufacturing process would benefit from automation and how automated manufacturing processes can improve productivity and reduce manufacturing costs. We also leverage contract manufacturers when strategically advantageous.

Operations

Our flash consists of flash-based memory, controllers and firmware and other components. Substantially all of our flash-based memory is obtained from our joint ventures with Kioxia, which provide us with leading-edge, high-quality and low-cost flash memory wafers. While substantially all of our flash memory supply utilized for our products are purchased from these ventures, from time to time, we also purchase flash memory from other flash manufacturers. Controllers are primarily designed in-house and manufactured by third-party foundries or acquired from third-party suppliers. Our assembly and test operations comprise in-house assembly and test facilities located in Penang, Malaysia and other contract manufacturers, and the assembly and test facility owned and operated by the SDSS Venture. The SDSS Venture is 20% owned by Sandisk and 80% owned by JCET. We believe the use of our in-house assembly and test facilities and manufacturing partners provide flexibility and give us access to increased production capacity.

We and Kioxia currently operate the Flash Ventures across seven flash-based manufacturing facilities in Japan, six of which are located in Yokkaichi, Japan and one of which is located in Kitakami, Japan. Flash Ventures will begin flash-based manufacturing operations at an eighth facility in Japan in calendar year 2025. Through Flash Ventures, we and Kioxia collaborate in the development and manufacture of flash-based memory wafers using semiconductor manufacturing equipment owned or leased by each of the Flash Ventures entities. We co-develop flash technologies (including process technology and memory design) with Kioxia for Flash Ventures’ use. We and Kioxia jointly own these co-developed flash technologies. We and Kioxia also contribute to the collaboration and license to each other technologies that are independently developed and owned by each of us and are reasonably necessary to our joint development or manufacture of flash-based memory. We hold a 49.9% ownership position in each of the Flash Ventures entities. We jointly control with Kioxia the operations of Flash

86

##### Table of Contents

Ventures, and we believe our participation in Flash Ventures helps us reduce product costs, increases our ability to control the quality of our products and speeds delivery of our products to our customers.

Kioxia owns the facilities and provides wafer manufacturing services to Flash Ventures at cost using manufacturing equipment owned or leased by Flash Ventures and process technologies co-owned or contributed by us and Kioxia. Flash Ventures accounts for approximately 80% of the total manufacturing capacity in the facilities owned by Kioxia. We and Kioxia are entitled to purchase a share of Flash Ventures’ output, which generally equals 50% each. The price for which we and Kioxia pay Flash Ventures for flash memory wafers is cost plus a small markup. We are obligated to pay for variable costs incurred in producing our share of Flash Ventures’ flash-based memory wafer supply, based on a rolling forecast. In addition, we are obligated to pay for half of Flash Ventures’ fixed costs regardless of the output we choose to purchase.

While Flash Ventures is operating, we and Kioxia are restricted from working with third parties to manufacture flash-based memory or from fabricating flash-based memory beyond the capacity specified in our agreements with Kioxia. In addition, we may not manufacture flash-based memory ourselves except to the extent that we acquire the manufacturing capacity of a Flash Ventures entity as a result of such entity’s dissolution or termination of its joint venture agreements or upon our acquisition of all the ownership interests in such entity.

The agreements governing the operations of the Flash Ventures entities also set out a framework for any investment by the joint venture partners in flash manufacturing capacity. We have jointly invested, and intend to continue to jointly invest, with Kioxia in the manufacturing equipment needed to support Flash Ventures’ flash manufacturing operations. In addition, we are obligated to fund 49.9% to 50.0% of capital investments that a Flash Ventures entity decided to make to the extent that the Flash Ventures entity’s operating cash flow is insufficient to fund these investments.

Each Flash Ventures entity operates for a set amount of time as agreed between us and Kioxia. Since the start of Flash Ventures, we and Kioxia have extended the term for all three of the Flash Ventures entities. Absent further extensions as mutually agreed between us and Kioxia, Flash Partners Ltd. and Flash Alliance Ltd. are currently set to expire on December 31, 2029, and Flash Forward Ltd. is currently set to expire on December 31, 2034. Each Flash Ventures entity’s joint venture agreements may also earlier terminate upon the occurrence of certain specified events, including earlier dissolution by agreement of the parties or an event of default or bankruptcy. Upon the expiration of a Flash Ventures entity’s joint venture agreements, whenever that may occur, the applicable Flash Ventures entity will commence a wind-up process and be dissolved. Net proceeds from the dissolution will be distributed in kind or cash to us and Kioxia on a pro rata basis based on our respective ownership positions. The applicable Flash Venture entity will continue to operate during the period of winding up.

On January 24, 2025, the Company and WDC entered into an equity transfer agreement (the “Equity Transfer Agreement”) to transfer WDC’s entire equity interest in Unisplendour Corporation Limited and Unissoft (Wuxi) Group Co. Ltd. (“Unis”), referred to as the “Unis Venture,” to the Company. The Unis Venture is 49% owned by the Company and 51% owned by Unis. The Unis Venture markets and sells the Company’s products in China and develops data storage systems for the Chinese market.

Prior to the execution of the Equity Transfer Agreement, the Unis Venture was not historically managed as a component of the Company and as such, the related equity method investment was not reflected within our Condensed Consolidated Financial Statements. After the execution of the Equity Transfer Agreement, the Company accounts for its investment in the Unis Venture under the equity method of accounting. The Company’s 49% interest in the earnings of the Unis Venture will be recognized one quarter in arrears from the date the Unis Venture was transferred to the Company and will be reported in Other expense, net in the Condensed Consolidated Statements of Operations.

DIRECTOR COMPENSATION

INTRODUCTION

On February 21, 2025, Sandisk Corporation became an independent publicly traded company as a result of its separation from WDC. Therefore, none of our directors received compensation from Sandisk for fiscal year 2024, and only certain of our non-employee directors, who served on the WDC Board of Directors prior to February 21, 2025, received compensation under WDC’s director compensation program for fiscal year 2024, which is described in further detail below. WDC’s non-employee director compensation program is designed to provide competitive compensation that is necessary to attract and retain qualified non-management directors. WDC’s annual non-employee director compensation program consists of a cash retainer and equity compensation in the form of restricted stock units (the “RSUs” or individually, an “RSU”). Management directors do not receive compensation for their service as director. Our non-employee director compensation program going forward is substantially similar to that of WDC’s prior to the separation.

WDC DIRECTOR COMPENSATION PROGRAM

The following section describes the elements and other features of WDC’s director compensation program for fiscal 2024 for non-employee directors.

Fiscal 2024 Non-Employee Director Cash Retainer Fees

Cash retainer fees are paid to WDC’s non-employee directors based on WDC Board of Directors 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 its non-employee directors for fiscal 2024.

Type of Fee |  | Current Annual Fee ($) |
Annual Retainer |  |  | 85,000 |
Additional Non-Employee Chair of the Board Retainer |  |  | 100,000 |
Additional Committee Member Retainers: |  |  |  |
Audit Committee |  |  | 15,000 |
Compensation and Talent Committee |  |  | 12,500 |
Governance Committee |  |  | 10,000 |
Additional Committee Chair Retainers: |  |  |  |
Audit Committee |  |  | 25,000 |
Compensation and Talent Committee |  |  | 22,500 |
Governance Committee |  |  | 15,000 |

Under WDC’s non-employee director compensation program, a non-employee director serving as Chair of the 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 the WDC Board of Directors, a WDC Board of Directors committee, or to one of the 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. WDC’s non-employee directors do not receive a separate fee for each board or committee meeting they attend. WDC reimburses its non-employee directors for reasonable out-of-pocket expenses incurred to attend each board or committee meeting.

With respect to the initial slate of Sandisk non-employee directors, members of the WDC Board of Directors who were appointed to the Sandisk Board of Directors (Ms. Alexy, Mr. Caulfield, Mr. Massengill and Ms. Suzuki)

101

##### Table of Contents

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 retainer fees.

Non-Employee Director Equity Awards

Under the WDC Non-Employee Director Restricted Stock Unit Grant Program, each of its non-employee directors automatically received for fiscal 2024 an award of RSUs equal in value to $240,000 (or, in the case of its non-employee director serving as Chair of the Board, $290,000, or, in the case of its Lead Independent Director, $280,000). WDC’s non-employee directors receive these awards immediately following the annual meeting of stockholders if he or she has been re-elected as a director at that meeting. In the case of a non-employee director who is newly elected or appointed after the date of the annual meeting, WDC grants a prorated award of RSUs for the year in which he or she is elected or appointed. Pursuant to its Non-Employee Director Restricted Stock Unit Grant Program, a non-employee director who was serving on the WDC Board pursuant to an investor’s contractual right received a cash award in lieu of RSUs. The amount of a cash award granted in lieu of RSUs is equal to the value of RSUs that the recipient would otherwise have been entitled to receive. The RSUs and cash awards granted in fiscal 2024 vested 100% upon the earlier of: (i) November 15, 2024 (the first anniversary of the grant date); and (ii) immediately prior to the first annual meeting of stockholders held after the grant date. With respect to the initial slate of Sandisk non-employee directors, each director received a prorated RSU award. In connection with our separation from WDC, each of the Sandisk non-employee directors received a prorated RSU award from Sandisk, with the award amounts determined based on the same award values used for WDC’s Non-Employee Director Restricted Stock Unit Grant Program.

Fiscal 2024 Non-Employee Director Equity Awards and Cash Retainers

On the date of WDC’s 2023 Annual Meeting (November 15, 2023), each non-employee director serving on the WDC Board, including those who were appointed to Sandisk’s Board of Directors upon the separation in February 2025, was automatically granted 5,213 RSUs (6,300 RSUs for its Chair of the Board and 6,082 RSUs for its Lead Independent Director) with these awards being received by directors in fiscal 2024. The closing price of WDC common stock on the Nasdaq Stock Market on November 15, 2023, was $46.03.

Each of our non-employee directors serving on the WDC Board of Directors in fiscal 2024 also received cash retainer fees in the amounts set forth above under the section titled “Fiscal 2024 Non-Employee Director Cash Retainer Fees.”

Deferred Compensation Plan for Non-Employee Directors

WDC permits each non-employee director to defer payment of up to 80% of his or her annual cash compensation in accordance with WDC’s deferred compensation plan (the “WDC Deferred Compensation Plan”). WDC also permits non-employee directors to defer payment of any RSUs awarded under its 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 its executive officers and other participants in its Deferred Compensation Plan. Sandisk adopted a substantially similar Deferred Compensation Plan in connection with the separation.

Treatment of Equity Incentive Arrangements in Connection with the Spin-off

Our directors’ RSU awards that were granted under WDC’s Non-Employee Director Restricted Stock Unit Grant Program prior to the spin-off were treated as follows upon our separation from WDC on February 21, 2025:

| • |  | Sandisk directors who continued to serve as WDC directors following the spin-off (as dual service directors) had their RSU awards converted into post-separation WDC RSU awards and Sandisk RSU

##### Table of Contents

| awards. The number of shares of WDC common stock subject to each post-separation WDC RSU award is equal to the same number of shares that were subject to the pre-separation RSU award, and the number of shares of Sandisk common stock subject to each post-separation Sandisk RSU award is equal to the number of shares of Sandisk common stock an individual holder of WDC common stock received in the distribution calculated based on the number of WDC shares of common stock subject to the pre-separation award.

| • |  | Sandisk directors who were previously WDC directors, but who only serve as Sandisk directors following the spin-off, had their RSU awards converted into Sandisk RSU awards, with adjustments intended to preserve the aggregate value of the equity award based on a ratio that took into account the pre-separation per share closing trading price of WDC common stock on the trading day prior to the separation and the average post-separation per share closing trading price of Sandisk common stock over 5 trading days following the separation.

| • |  | Any Sandisk directors who elected to defer payment of their WDC RSU awards continue to retain the deferred payment of such awards pursuant to WDC’s plans and programs following the spin-off, with adjustments intended to preserve the aggregate value of the equity award based on a ratio that took into account the pre-separation per share closing trading price of WDC common stock on the trading day prior to the separation and the average post-separation per share closing trading price of WDC common stock over 5 trading days following the separation.

EXECUTIVE COMPENSATION

COMPENSATION DISCUSSION AND ANALYSIS

On February 21, 2025, Sandisk became an independent, publicly traded company as a result of its separation from WDC. Therefore, this Compensation Discussion and Analysis (“CD&A”) and the related compensation tables include information regarding compensation paid by, and executive compensation policies and practices of, WDC as they relate to our named executive officers prior to the separation, which are similar to Sandisk’s compensation structure following the separation.

For purposes of this CD&A and the executive compensation tables that follow, the following individual is our “named executive officer” (the “NEO”) who served during the fiscal year that ended June 28, 2024:

| • |  | David V. Goeckeler, Chief Executive Officer

Luis F. Visoso, our Executive Vice President and Chief Financial Officer (our “Chief Financial Officer”), was not an employee of WDC during fiscal 2024. As described below, WDC entered into an offer letter with Mr. Visoso on July 1, 2024, which provided for Mr. Visoso’s employment with WDC to transfer to Sandisk September 28, 2024. Accordingly, Mr. Visoso was not an NEO for fiscal 2024; however, we have included below a summary of the material terms of his offer letter.

The following sections of this CD&A describe WDC’s executive compensation philosophy, executive compensation program elements and certain of WDC’s executive compensation plans, policies and practices for fiscal 2024, as well as, to the extent known, certain aspects of Sandisk’s anticipated compensation program following the spin-off.

| • |  | Section 1—Executive Compensation Philosophy, Objectives and Process

| • |  | Section 2—Updates to Fiscal 2024 Executive Compensation Program

| • |  | Section 3—Decisions and Outcomes

| • |  | Section 4—Fiscal 2025 Decisions

| • |  | Section 5—Other Program Features and Policies

SECTION 1—EXECUTIVE COMPENSATION PHILOSOPHY, OBJECTIVES AND PROCESS

The summary below provides the key objectives of WDC’s executive compensation program prior to the separation:

Attract, retain and motivate premier talent necessary to accelerate its growth and drive financial, operational and market performance |  | Provide competitive target compensation relative to the technology industry in which it competes for business and talent |  | Encourage accountability by tying a substantial portion of each executive officer’s target total direct compensation opportunity to individual, corporate and market-based performance objectives that it expects to create long-term value for stockholders
Pay for performance by providing a substantial portion of compensation in the form of “at-risk,” variable incentive compensation awards that reward superior individual, corporate and market-based performance and that reduce pay for underperformance |  | Align the interests of executive officers with stockholders through pay-for-performance compensation design and by granting long-term equity awards that include multi-year performance or service vesting requirements

As discussed above, until the consummation of the separation, Sandisk was part of WDC and was not an independent company. Prior to the spin-off, the WDC Compensation and Talent Committee made certain compensation decisions and took actions regarding our compensation philosophy, principles and program design, and following the spin-off, the Sandisk Compensation and Talent Committee made additional compensation decisions and took further actions.

After the spin-off, the WDC Compensation and Talent Committee and the Sandisk Compensation and Talent Committee established objectives and principles similar to the objectives and principles that WDC maintained for its compensation program in fiscal 2024, as described in this Compensation Discussion and Analysis. The Sandisk Compensation and Talent Committee expects to continue to refine Sandisk’s executive compensation policies and practices to align with its business needs, stockholder value, and peer group practices going forward.

WDC’s 2024 Executive Compensation Decisions

Because Sandisk has been an independent company only since February 2025, the decisions impacting executive compensation with respect to fiscal year 2024 were made by WDC and grounded in its executive compensation philosophy and policies.

Elements of WDC’s Fiscal 2024 Executive Compensation Program

WDC believes its emphasis on variable compensation aligns with its focus on operating excellence and allows its executive compensation levels to reflect its performance. After evaluating its variable compensation plans with its independent compensation consultant, the WDC Compensation and Talent Committee approved the incentive compensation design summarized below for fiscal 2024.

Its actual pay positioning for each of its named executive officers varies based upon the WDC Compensation and Talent Committee’s review of its proxy peer group and survey market data, competitive pay levels for comparable roles and each executive officer’s role, past performance, scope of responsibility and expected future contributions.

In addition to the elements reflected below, WDC also provides its executive officers with limited perquisites and certain other indirect benefits, as described in the section below entitled “Other Program Features and Policies.”

WDC’s Process for Determining Executive Compensation

The WDC Compensation and Talent Committee reviewed and determined compensation for its executive officers, including Mr. Goeckeler prior to the separation. The WDC Compensation and Talent Committee reviews the performance and compensation of its executive officers on an annual basis and at the time of hiring, promotion or other change in responsibilities. The WDC Compensation and Talent Committee’s annual review typically occurs near the end of the prior fiscal year and beginning of the new fiscal year.

The WDC Compensation and Talent Committee also considers views and input received through stockholder outreach and engagement efforts when making determinations regarding its executive compensation program.

107

##### Table of Contents

In determining WDC’s fiscal 2024 executive compensation program design, the WDC Compensation and Talent Committee’s executive compensation decisions were informed by several factors, including:

EXTERNAL AND INTERNAL FACTORS |  | COMPENSATION CONSULTANT
•  WDC’s compensation philosophy and objectives •  WDC’s pay positioning relative to WDC’s proxy peer group and broad compensation survey market data •  The executive officer’s role, experience, performance and contributions •  Internal pay equity •  WDC’s retention objectives •  Succession planning •  Current and historical company performance and strategic and financial goals •  Market performance and general economic conditions |  | •  Views from the WDC Compensation and Talent Committee’s independent compensation consultant •  Compensation survey and proxy peer group company market data prepared by the independent compensation consultant MANAGEMENT •  The CEO’s recommendations for WDC’s other executive officers (not including himself) •  The CFO’s input on financial targets for WDC’s performance-based incentive compensation program, data regarding the impact of the program on WDC’s financial results and actual results against WDC’s pre-established performance targets •  Internal and external compensation data provided by WDC’s Chief People and Inclusion Officer and other staff STOCKHOLDERS •  Feedback received during stockholder outreach and engagement efforts

The WDC Compensation and Talent Committee engaged Compensia, Inc. (“Compensia”) as its independent compensation consultant in fiscal 2024. Compensia reported directly to the WDC Compensation and Talent Committee and communicated with management to gather information and review management proposals as needed. Compensia attended all regularly scheduled meetings of the WDC Compensation and Talent Committee during fiscal 2024 and its responsibilities for fiscal 2024 generally included:

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

| • |  | Reviewing and advising on compensation design and amounts for non-employee members of the WDC Board of Directors

| • |  | Providing recommendations regarding the composition and selection of WDC’s proxy peer group companies

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

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

| • |  | Advising on the compensation-related items approved by the WDC Compensation and Talent Committee in connection with the strategic review of WDC’s business

The WDC Compensation and Talent Committee assessed the independence of Compensia pursuant to applicable rules and regulations of the SEC and the Nasdaq Stock Market and concluded that the engagement of Compensia did not raise any conflicts of interest during fiscal 2024 and currently does not raise any conflicts of interest.

Comparative Market Data

For fiscal 2024, the WDC Compensation and Talent Committee determined the composition of WDC’s proxy peer group with market data collected from the Radford Global Compensation Database, an independently published survey. The survey data was filtered to screen for companies in WDC’s proxy peer group that participate in the survey and, for executive roles in which such survey screen resulted in insufficient data, a broader screen of technology companies as adjusted for revenue size was used. With input from its independent compensation consultant, the WDC Compensation and Talent Committee considered such market data and industry practices during its annual review of the competitiveness of WDC’s compensation levels and the appropriate mix of compensation elements for WDC’s named executive officers. This market data provided the WDC Compensation and Talent Committee a reference point, which was one of several factors that it used to make compensation decisions during its fiscal 2024 annual compensation review.

Fiscal 2024 Proxy Peer Group Companies for Benchmarking Pay and Incentive Design

The proxy peer group companies that the WDC Compensation and Talent Committee used for comparative pay and incentive design purposes for fiscal 2024 consisted of technology companies that compete with WDC for talent and have the size (primarily based on revenue) and business characteristics that WDC believes are comparable. Like WDC, many companies included in WDC’s proxy peer group are included in the Dow Jones U.S. Technology Hardware & Equipment Index.

In choosing companies for WDC’s proxy peer group, the WDC Compensation and Talent Committee focused primarily on industry, talent market and revenue size. Revenue is a commonly used proxy for organizational size and complexity and is typically stable from year-to-year, making it a valuable metric when selecting peers for executive compensation purposes. As part of its decision process, the WDC Compensation and Talent Committee also referenced other metrics for informational purposes, including comparative market capitalization and profitability metrics.

SECTION 2—UPDATES TO FISCAL 2024 EXECUTIVE COMPENSATION PROGRAM

Fiscal 2024 Short-Term Incentives

The WDC Compensation and Talent Committee implemented a number of enhancements to WDC’s short-term incentives (the “STI”) design, beginning in fiscal 2024, which were responsive to perspectives and feedback shared by WDC’s stockholders during WDC’s year-round engagement efforts.

109

##### Table of Contents

After assessing WDC’s fiscal 2024 objectives, market conditions and considering stockholder feedback, the WDC Compensation and Talent Committee approved the following STI design for fiscal 2024:

* | The Individual Modifier did not increase award payout if WDC’s non-GAAP operating income was below the minimum performance level.

The WDC Compensation and Talent Committee eliminated the exabytes shipped metrics and the individual performance metric included in the fiscal 2023 STI and replaced them with a cash conversion cycle metric and an emissions metric. The cash conversion cycle metric measures the length of time it takes to convert WDC’s working capital investments into cash, which the WDC Compensation and Talent Committee believes complements non-GAAP operating income by focusing WDC’s executive officers on both profitability and managing working capital (inventory, receivables and payables) to generate cash. The emissions metric aligns WDC’s executive officers’ compensation to progress on WDC’s Scope 1 and Scope 2 emissions reduction targets.

The individual performance modifier in the fiscal 2024 STI includes execution and leadership goals for each executive and corporate ESG goals focused on inclusion and governance. The individual performance modifier may not increase award payout (but can still decrease the payout) if WDC’s non-GAAP operating income performance is below the minimum performance level for that metric.

Fiscal 2024-2026 Performance Stock Units

Pursuant to the employee matters agreement entered into by and between WDC and Sandisk effective February 21, 2025, the outstanding WDC PSUs (including those granted in fiscal 2024) held by WDC employees who would be employed by us following the separation, including Mr. Goeckeler, were converted to time-based Sandisk RSUs, assumed under the Sandisk 2025 Long-Term Incentive Plan and are no longer subject to performance-based vesting conditions. The Fiscal 2024-2026 PSUs had a relative TSR modifier that modifies PSU payouts with a multiplier ranging from +/- 10% based on WDC’s performance relative to the S&P 500 Information Technology Index constituents as of the beginning of the performance period. The modifier compares WDC’s three-year TSR performance to the median company in the index based on three-year TSR performance.

Fiscal 2024 STI Design and Performance

As discussed in more detail in the section entitled “Updates to Fiscal 2024 Executive Compensation Program,” the WDC Compensation and Talent Committee updated the STI design to reflect investor feedback during WDC’s prior stockholder outreach and engagement. WDC’s fiscal 2024 STI design is reflected below. The individual modifier component for each of its named executive officers, including Mr. Goeckeler, included goals tied to leadership, execution and ESG targets.

* | The Individual Modifier may not increase award payout if WDC’s non-GAAP operating income is below the minimum performance level.

Fiscal 2024 Corporate Performance

The WDC Compensation and Talent Committee approved fiscal 2024 performance targets that incentivized its executive officers to improve WDC’s profitability and increase efficiency in converting working capital investments into cash. At the time the WDC Compensation and Talent Committee approved fiscal 2024 performance targets in August 2023, WDC was in the midst of a significant market downturn with uncertainty as to the timing and strength of a market recovery. In this context, the fiscal 2024 non-GAAP operating income metric still required improvement on fiscal 2023 results for its executive officers to receive any payout on this metric. The WDC Compensation and Talent Committee also approved a robust emissions target that aligns with WDC’s public commitments around Scope 1 and Scope 2 emissions, which is an important factor for WDC’s largest customers that are seeking to mitigate emissions within their supply chains.

Fiscal 2024 Individual Performance Modifier

Performance Goal Setting

The individual performance modifier for each WDC named executive officer’s target incentive award opportunity was split equally between leadership, execution and ESG goals. WDC’s named executive officers (other than WDC’s CEO) worked with WDC’s CEO to establish individual performance goals, with input from the WDC Compensation and Talent Committee. Mr. Goeckeler separately submitted his fiscal 2024 performance goals for the WDC Compensation and Talent Committee’s review, with input from the WDC Board of Directors. These performance goals are summarized below.

Long-Term Incentives: Fiscal 2024 Equity Awards

Fiscal 2024 Long-term Incentive Awards

Our named executive officer received long-term incentive (the “LTI”) awards in August 2023 consisting of a mix of PSUs and RSUs. The table below summarizes the LTI mix awarded to Mr. Goeckeler, in his capacity as WDC’s CEO, for fiscal 2024. The RSUs are scheduled to vest with respect to 25% of the award on the first anniversary of the grant date and with respect to 6.25% of the award quarterly thereafter for three years. The vesting provisions of the PSUs are described below under the section entitled “Fiscal 2024-2026 PSU Awards.”

Named Executive Officer(1) |  | Total LTI Target Grant Value ($)(1) |  |  | LTI Vehicle Mix |
| PSUs |  |  | RSUs |

| of a Monte Carlo simulation to determine the grant date fair value of the PSUs. In addition, under financial accounting rules, the grant date fair value for a PSU award is not determined until the fiscal year in which the performance metrics are established. The performance metrics are determined annually by the WDC Compensation and Talent Committee for each of fiscal 2024, 2025 and 2025. Accordingly, only the grant date fair value for the portion attributable to fiscal 2024 is reflected in the “Fiscal 2024 Summary Compensation Table” and the “Fiscal 2024 Grants of Plan-Based Awards Table” for this portion of the award.

Fiscal 2022-2024 PSU Awards: Performance and Payout

The PSUs granted in fiscal 2022 reflected the following design:

| • |  | Financial Performance Metrics (50% Weighting)

| • |  | The fiscal 2022–2024 PSUs included three-year performance periods for the financial metrics (revenue and non-GAAP EPS) that were subject to a pre-established, objective adjustment at the end of the performance period in a relative proportion (up or down) by which the total market for WDC’s products (measured by revenue) during the period exceeded or fell short of the total market forecast approved by the WDC Compensation and Talent Committee at the time the goals were established, as

116

##### Table of Contents

| reported by industry analysts. WDC refers to the relative market performance adjustment described in this CD&A as “relative MPA.” The relative MPA modifier helped ensure that WDC pays for performance relative to the market demand and opportunity available to WDC.

| • |  | The actual market for WDC’s products was lower than forecast when the fiscal 2022–2024 PSU goals were established, thus applying the relative MPA modifier resulted in a reduction in both revenue and non-GAAP EPS targets.

| • |  | Relative TSR Metric (50% Weighting)

| • |  | The fiscal 2022-2024 PSUs included a three-year TSR metric that measured WDC’s stock performance relative to a TSR peer group consisting of the constituents of the S&P 500 Index as of the beginning of the performance period.

SECTION 4—FISCAL 2025 DECISIONS

Fiscal 2025 Compensation Changes

In fiscal 2024, the WDC Compensation and Talent Committee, in connection with its annual review of the WDC executive officers’ compensation levels and input from its independent compensation consultant, approved fiscal 2025 compensation changes for its named executive officers, including Mr. Goeckeler, effective on June 29, 2024, to reflect market compensation levels and to recognize strong performance by the executive team while continuing to align executive compensation with long-term stockholder interests.

Mr. Goeckeler’s base salary was increased to $1,300,000, and his target LTI award was increased to $16,250,000.

Fiscal 2025 LTI Awards

The WDC Compensation and Talent Committee granted the following LTI awards to Mr. Goeckeler in fiscal 2025, as part of WDC’s annual LTI program:

Named Executive Officer |  | Total LTI Target Grant Value ($)(1) |  |  | LTI Vehicle Mix |
| PSUs |  |  | RSUs |
David V. Goeckeler |  |  | 16,250,000 |  |  |  | 60 | % |  |  | 40 | %

Spin-Off Related Cash Transaction Bonus

On January 25, 2025, WDC granted Mr. Goeckeler a cash transaction bonus in connection with the spin-off, in an amount equal to 24 times his then-current monthly base salary. The transaction bonus payment was made by Sandisk post-separation and is subject to repayment terms for 12 months following the separation in the event of specified termination events.

SECTION 5—OTHER PROGRAM FEATURES AND POLICIES7

Perquisites |  | We provide our executive officers with limited perquisites and other personal benefits, consisting principally of a $5,000 annual allowance for financial planning services (net of taxes) and, in very limited circumstances, tax gross-ups for certain payments. 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 and productivity. 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 |  | 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 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 the 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” (qualifying termination in connection with a change in control) for payment and the plan does not provide any tax gross-up payments for participants. Please see the section entitled “Executive Compensation Tables and Narratives—Potential Payments upon Termination or Change in Control” for a description and quantification of the potential payments that may be made to WDC’s named executive officers in connection with their termination of employment or a change in control of WDC (based on its severance arrangements that existed as of the end of fiscal 2024). The spin-off transaction did not constitute a change in control of WDC under WDC’s Change in Control Severance Plan. In connection with the separation, Sandisk has adopted substantially similar change in control protections for its executive officers.
Employment Agreements |  | As described in further detail below under “Offer Letters,” WDC entered into an offer letter dated July 1, 2024 with our Chief Financial Officer, Mr. Visoso. The offer letter provided for Mr. Visoso’s employment with WDC to transfer to Sandisk. Mr. Goeckeler is not currently party to an employment agreement with Sandisk.
Compensation Recovery (Clawback) Policy |  | Our 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 will be publicly filed with our fiscal 2025 Annual Report on Form 10-K.
Misconduct Policies |  | We maintain several policies relating to employee misconduct. In the event an executive officer’s employment is terminated for cause due to their misconduct or violation of company policy, among other reasons, they 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.

##### Table of Contents

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, deferred stock units 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.

EXECUTIVE COMPENSATION TABLES AND NARRATIVES

As required by applicable SEC rules, information in the tables below regarding compensation paid to or earned by Mr. Goeckeler for fiscal 2024 relates to compensation paid by, and executive compensation policies and practices of, WDC as in effect in fiscal 2024 and prior to the separation. Where applicable, we have summarized below executive compensation policies and practices applicable to Sandisk following the separation.

Fiscal 2024 Summary Compensation Table

The following table presents information regarding compensation earned for fiscal 2024 by Mr. Goeckeler.

Name and Principal Position |  | Fiscal Year |  |  | Salary ($) |  |  | Bonus ($) |  |  | Stock Awards ($)(1) |  |  | Non-Equity Incentive Plan Compensation ($)(2) |  |  | All Other Compensation ($)(3) |  |  | Total ($) |

(1) | The amounts shown reflect the aggregate grant date fair value of stock awards granted in the applicable fiscal year computed in accordance with ASC Topic 718. These amounts were calculated based on the assumptions described in Note 12 in the Notes to Consolidated Financial Statements included in WDC’s 2024 Annual Report on Form 10-K. For PSU awards, amounts include the grant date fair value of the 20242026 PSUs and the 2023-2025 PSUs, in each case, as related to the fiscal 2024 performance period because only the annual targets for such performance periods were established in fiscal 2024, and thus, such portions of the awards are deemed granted for financial accounting purposes during fiscal 2024. The grant date fair value of the remaining PSUs under the 2024-2026 and 2023-2025 PSU awards will be reflected in the Summary Compensation Table after the spin-off in a manner consistent with their conversion to RSUs.

The following amounts represent the grant date fair value of PSU awards granted to Mr. Goeckeler during fiscal 2024 assuming the probable outcome of the awards on the grant date and assuming maximum performance under the awards deemed granted during fiscal 2024. WDC considered the probable outcome of the awards based on the target level of performance for PSUs except for PSUs that are subject to relative TSR or stock price CAGR conditions, which were determined using a Monte Carlo simulation. As stated

(a) | The amount shown reflects personal travel on an aircraft, in which WDC owns a fractional interest, with the aggregate incremental cost incurred by WDC of $74,866. Pursuant to WDC policy, as WDC’s then-CEO, Mr. Goeckeler was required to reimburse WDC for the amount of aggregate incremental cost in excess of $250,000 per fiscal year in connection with any personal use of such aircraft. Incremental cost for a personal flight is calculated based on the full amount of the direct variable operating cost charged to WDC for the applicable flight. Variable operating cost covers fees and costs related to, if applicable, aircraft use, fuel, flight fees, landing fees, cleaning, catering and taxes. Mr. Goeckeler is responsible for all personal income taxes associated with such personal usage.

Description of Sandisk Compensation Arrangements for Named Executive Officer

Non-Equity Incentive Plan Compensation and Awards

In connection with the spin-off, the Sandisk Board of Directors adopted our Executive Short-Term Incentive Plan (the “Sandisk STI Plan”). Our named executive officer is eligible to receive cash incentive awards on an annual basis under the Sandisk STI Plan (as described below), which generally mirrors the WDC STI Plan, except as otherwise determined by the Sandisk Compensation and Talent Committee.

Sandisk Executive Short-Term Incentive Plan

The purpose of the Sandisk STI Plan is to promote the success of Sandisk by (i) compensating and rewarding participating executives with incentive awards for the achievement of performance goals, (ii) motivating such executives by giving them opportunities to receive incentive awards directly related to performance, and (iii) retaining executives by offering them an opportunity to share in the Company’s success.

Administration

The Sandisk STI Plan is administered by the Sandisk Compensation and Talent Committee.

Incentive Awards

As the administrator, the Sandisk Compensation and Talent Committee has the sole discretion to determine the performance goals and criteria for each award under the Sandisk STI Plan. The Sandisk Compensation and

122

##### Table of Contents

Talent Committee establishes the formula to be used to determine any incentive award payable under the Sandisk STI Plan, and whether all or any portion of the amount so calculated will be paid, subject in all cases to the terms, conditions and limits of the plan.

Any incentive award earned and payable in accordance with the plan will be paid in cash (subject to tax withholding) as soon as reasonably practicable following the determination of such incentive award amount, but in no event later than (a) March 15 of the calendar year following the calendar year in which the applicable performance period ends, or (b) if later, the last day of the period ending on the 15th day of the third month following the end of the Company’s fiscal year in which the applicable performance period ends.

Adjustments

The Sandisk Compensation and Talent Committee has sole discretion to adjust the performance measures, performance goals, relative weights of the measures and other provisions of then-outstanding awards under the Sandisk STI Plan to reflect items related to, among other things, a change in accounting principle, acquisitions, disposal of a business, discontinued operations and other events or changes in applicable law or business conditions.

Corporate Transactions

The Sandisk Compensation and Talent Committee has discretion to settle or terminate, as the Sandisk Compensation and Talent Committee may determine in its sole discretion and (in the case of a settlement) in such amount (if any) as the Sandisk Compensation and Talent Committee may determine to be appropriate in its sole discretion, any award granted under the Sandisk STI Plan in connection with any merger, reorganization or other corporation transaction.

Clawback Provisions

All awards and any incentive award paid under the Sandisk STI Plan are subject to the provisions of any clawback or similar policy implemented by the Company from time to time, including, without limitation, any clawback or similar policy adopted to comply with the requirements of applicable law, such as the Dodd-Frank Wall Street Reform and Consumer Protection Act and any rules or regulations promulgated thereunder, to the extent set forth in such clawback.

Equity-Based Awards

Each RSU and PSU award reported in the “Fiscal 2024 Grants of Plan-Based Awards Table” was granted by the WDC Compensation and Talent Committee under, was subject to, the terms of the WDC 2021 Long-Term Incentive Plan, and in connection with the separation, assumed by the Sandisk 2025 Long-Term Incentive Plan.

Our named executive officer is not entitled to voting rights with respect to their Sandisk stock units (PSUs and RSUs). However, if Sandisk pays an ordinary cash dividend on Sandisk’s 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.

Information regarding the vesting acceleration provisions applicable to equity awards granted to Mr. Goeckeler under the WDC CIC Severance Plan and the WDC Executive Severance Plan is included in the section entitled “Potential Payments upon Termination or Change in Control” below. The Sandisk CIC Severance Plan and the Sandisk Executive Severance Plan, each as defined below and adopted by Sandisk in connection with the separation, generally mirror WDC’s change in control severance plan.

123

##### Table of Contents

The LTI awards held by our employees, including Mr. Goeckeler and our Chief Financial Officer, that are converted into Sandisk LTI awards were assumed under the 2025 LTIP (defined below).

Sandisk 2025 Long-Term Incentive Plan

In connection with the spin-off, our Board adopted, and WDC as our then-sole stockholder approved, our 2025 Long-Term Incentive Plan (the “2025 LTIP”), which became effective upon the consummation of the spin-off. The following summary is qualified in its entirety by the full text of the 2025 LTIP, which is included as Exhibit 10.24 to the registration statement on Form S-1 of which this prospectus forms a part.

Purpose

The 2025 LTIP, through the granting of awards, is intended to help Sandisk secure and retain the services of eligible award recipients, provide incentives for such persons to exert maximum efforts for the success of our company and any affiliate and provide a means by which the eligible award recipients may benefit from increases in the value of our common stock.

Administration

Our Board has the authority to administer the 2025 LTIP, including the powers to: (i) determine who will be granted awards and what type of award, when and how each award will be granted, the provisions of each award (which need not be identical), the number of shares or cash value subject to an award and the fair market value applicable to an award; (ii) construe and interpret the 2025 LTIP and awards granted thereunder and establish, amend and revoke rules and regulations for administration of the 2025 LTIP and awards, including the ability to correct any defect, omission or inconsistency in the 2025 LTIP or any award document; (iii) settle all controversies regarding the 2025 LTIP and awards granted thereunder; (iv) accelerate or extend, in whole or in part, the time during which an award may be exercised or vested or at which cash or shares may be issued; (v) amend or terminate the 2025 LTIP; (vi) submit any amendment to the 2025 LTIP for stockholder approval; (vii) approve forms of award documents for use under the 2025 LTIP and amend the terms of any one or more outstanding awards; (viii) generally exercise such powers and perform such acts as our Board may deem necessary or expedient to promote the best interests of our company and that are not in conflict with the provisions of the 2025 LTIP or any award documents; and (ix) adopt procedures and sub-plans as are necessary or appropriate.

Subject to the provisions of the 2025 LTIP, our Board may delegate all or some of the administration of the 2025 LTIP to a committee of one or more directors and may delegate to one or more officers the authority to designate employees who are not officers to be recipients of options and stock appreciation rights (and, to the extent permitted by applicable law, other stock awards) and, to the extent permitted by applicable law, to determine the terms of such awards and the number of shares of common stock to be subject to such stock awards granted to such employees. Unless otherwise provided by our Board, delegation of authority by our Board to a committee or an officer will not limit the authority of our Board. All determinations, interpretations and constructions made by our Board (or another authorized committee or officer exercising powers delegated by our Board) in good faith will be final, binding and conclusive on all persons.

No Repricing

Neither an option nor a stock appreciation right may be modified to reduce the exercise price thereof nor may a new option, stock appreciation right or other award at a lower price be substituted or exchanged for a surrendered option or stock appreciation right (other than certain capitalization adjustments or substitutions in accordance with the 2025 LTIP), unless such action is approved by our stockholders.

124

##### Table of Contents

Eligibility

Persons eligible to receive awards under the 2025 LTIP include officers and employees of our company or any of our subsidiaries, members of our Board and certain consultants and advisors.

Aggregate Share Limit

The maximum number of shares of our common stock that may be issued or transferred pursuant to awards under the 2025 LTIP is 17,383,590 (the “Share Reserve”), which does not include the additional number of shares that reflect the converted WDC equity awards, subject to adjustment as set forth in the 2025 LTIP.

Additional Share Limits

The following other limits are also contained in the 2025 LTIP. These limits are in addition to, and not in lieu of, the share limit for the 2025 LTIP described above.

| • |  | The maximum number of shares that may be delivered pursuant to options qualified as incentive stock options granted under the 2025 LTIP is equal to 5 million shares annually and no individual may receive more than 1 million shares.

| • |  | The value of the shares subject to awards granted under the 2025 LTIP, together with any cash compensation awarded to any one non-employee director in any one “grant year” may not exceed $900,000.

This limit would not apply as to any award granted to an individual for services in a capacity other than as a non-employee director, even if such individual is, was or becomes a non-employee director.

To the extent that an award granted under the 2025 LTIP is settled in cash or a form other than shares, the shares that would have been delivered had there been no such cash or other settlement will not be counted against the shares available for issuance under the 2025 LTIP. In the event that shares are delivered in respect of a dividend equivalent right granted under the 2025 LTIP, only the actual number of shares delivered with respect to the award shall be counted against the share limits of the 2025 LTIP. To the extent that shares are delivered pursuant to the exercise of a stock appreciation right or stock option, the number of underlying shares as to which the exercise relates shall be counted against the applicable share limits, as opposed to only counting the shares actually issued. Shares that are subject to or underlying awards granted under the 2025 LTIP that are not paid or delivered (whether due to expiration, cancellation, termination, forfeiture, failure to vest or any other reason) will again be available for subsequent awards under the 2025 LTIP. In addition, the 2025 LTIP generally provides that shares issued in connection with awards that are granted by or become obligations of our company through the assumption of awards (or in substitution for awards) in connection with an acquisition of another company will not count against the shares available for issuance under the 2025 LTIP.

Shares that are reacquired or withheld by us as full or partial payment in connection with a full-value award under the 2025 LTIP, as well as shares reacquired or withheld by us to satisfy the tax withholding obligations related to a full-value award under the 2025 LTIP, will not count against the share limit of and will be available for new award grants under the 2025 LTIP. Shares that are reacquired or withheld by us in connection with the exercise of stock options, the settlement of stock appreciation rights or the payment of required withholding taxes on stock options or stock appreciation rights are not, however, available for new award grants.

Types of Awards

The 2025 LTIP authorizes stock options, stock appreciation rights, restricted stock, restricted stock units, performance stock awards, cash awards and other stock-based awards. The 2025 LTIP retains flexibility to offer competitive incentives and to tailor benefits to specific needs and circumstances. Any award may be paid or settled in cash.

125

##### Table of Contents

Minimum Vesting Requirements

Except pursuant to any required accelerated vesting in connection with a change in control event or in connection with retirement, death or disability, or as described below, the 2025 LTIP provides that each award granted under the 2025 LTIP will be subject to a minimum vesting period of one year. Awards may, however, be granted under the 2025 LTIP with minimum vesting requirements of less than one year, or no vesting requirements, provided that the total number of shares of our common stock subject to such awards will not exceed 5% of the aggregate share limit. This minimum vesting requirement under the 2025 LTIP does not limit or restrict the administrator’s discretion to accelerate or provide for the acceleration of vesting of any award in any circumstances it determines to be appropriate.

Deferrals

The administrator may provide for the deferred payment of awards, and may determine the other terms applicable to deferrals. The administrator may provide that deferred settlements include the payment or crediting of interest or other earnings on the deferred amounts, or the payment or crediting of dividend equivalents where the deferred amounts are denominated in shares.

Change in Control

Unless provided otherwise in an award agreement or other agreement between a participant and Sandisk or a subsidiary or expressly provided by our Board at the time of grant, then in the event of a change in control, our Board will take one or more of the following actions with respect to each outstanding award, contingent upon the closing or completion of the change in control:

| • |  | Arrange for the surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company) to assume or continue the award or to substitute a similar stock award for the award (including, but not limited to, an award to acquire the same consideration per share paid to our stockholders pursuant to the change in control)

| • |  | Arrange for the assignment of any reacquisition or repurchase rights held by our company in respect of common stock issued pursuant to the award to the surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company)

| • |  | Accelerate the vesting, in whole or in part, of the award (and, if applicable, the time at which the award may be exercised) to a date prior to the effective time of such change in control as determined by our Board, with such award terminating if not exercised (if applicable) at or prior to the effective time of the change in control, and with such accelerated vesting (and if applicable, such exercise) reversed if the change in control does not become effective

| • |  | Arrange for the lapse, in whole or in part, of any reacquisition or repurchase rights held by our company with respect to the award

| • |  | Cancel or arrange for the cancellation of the award, to the extent not vested or not exercised prior to the effective time of the change in control, in exchange for such cash consideration, if any, as our Board, in its reasonable determination, may consider appropriate as an approximation of the value of the canceled award

| • |  | Cancel or arrange for the cancellation of the award, to the extent not vested or not exercised prior to the effective time of the change in control, in exchange for a payment equal to the excess, if any, of (A) the value in the change in control of the property the participant would have received upon the exercise of the award immediately prior to the effective time of the change in control, over (B) any exercise price payable by such holder in connection with such exercise

Our Board need not take the same action or actions with respect to all awards or portions thereof or with respect to all participants and may take different actions with respect to the vested and unvested portions of an award.

In the absence of any affirmative determination by our Board at the time of a change in control, each outstanding award will be assumed or an equivalent award will be substituted by such applicable successor corporation, unless the successor corporation does not agree to assume the award or to substitute an equivalent award, in which case the vesting of such award will accelerate in its entirety (along with, if applicable, the time at which the award may be exercised) to a date prior to the effective time of such change in control as our Board will determine (or, if our Board does not determine such a date, to the date that is five days prior to the effective date of the change in control), with such award terminating if not exercised (if applicable) at or prior to the effective time of the change in control, and with such exercise reversed if the change in control does not become effective. However, the holder of a stock option or stock appreciation right will be given reasonable advance notice of the impending termination and a reasonable opportunity to exercise his or her outstanding vested stock options and stock appreciation rights (after giving effect to any accelerated vesting required in the circumstances) in accordance with their terms before the termination of such awards (except that in no case shall more than ten days’ notice of the impending termination be required and any acceleration of vesting and any exercise of any portion of an award that is so accelerated may be made contingent upon the actual occurrence of the event).

Transfer Restrictions

Subject to certain exceptions contained in the 2025 LTIP, awards generally are not transferable by the recipient other than by will or the laws of descent and distribution and are generally exercisable, during the recipient’s lifetime, only by the recipient. Any amounts payable or shares issuable pursuant to an award generally will be paid only to the recipient or the recipient’s beneficiary or representative. In addition, the 2025 LTIP provides that an award of restricted stock may not be transferred to any financial institution without prior stockholder approval.

Adjustments

Each share limit and the number and kind of shares available under the 2025 LTIP and any outstanding awards, as well as the exercise or purchase prices of awards, are subject to adjustment in the event of certain corporate events. These events include reclassifications, recapitalizations, stock splits (including a stock split in the form of a stock dividend) or reverse stock splits, mergers, combinations, consolidations, other reorganization, spin-off, split-up, similar extraordinary dividend distribution in respect of our common stock, exchange of common stock or other securities of our company, or other similar, unusual or extraordinary corporate events in respect of our common stock.

Termination of or Changes to the 2025 LTIP

Our Board may amend or terminate the 2025 LTIP at any time and in any manner. Stockholder approval for an amendment will be required only to the extent then required by applicable law or deemed necessary or advisable by our Board. No awards will be granted after the tenth anniversary of the 2025 LTIP’s initial effective date. Outstanding awards, as well as the administrator’s authority with respect thereto, generally will continue following the expiration or termination of the 2025 LTIP.

Specific Benefits under the 2025 LTIP

We have not approved any awards under the 2025 LTIP, other than the assumed awards as described above. The number and type of awards that we may grant in the future under the 2025 LTIP is not determinable.

We will grant RSUs under the 2025 LTIP to each of our non-employee directors immediately following the first Annual Meeting. These annual grants will be made under our Non-Employee Director Restricted Stock Unit Grant Program (as further described below in the section titled “Non-Employee Director Equity Awards”) and determined based on the closing price of our common stock on the Nasdaq Stock Market on the grant date. The actual number of shares that we may issue to our non-employee directors under our Non-Employee Director

##### Table of Contents

Restricted Stock Unit Grant Program depends on, among other future variables, the number of our non-employee directors from time to time, when a non-employee director serves as Chair of the Board or Lead Independent Director, the price of our common stock on the applicable grant date that is used to convert the applicable grant-date value into a number of shares, and whether our Board changes the applicable grant date values or other aspects of our non-employee director compensation program in the future.

Sandisk 2025 Employee Stock Purchase Plan

In connection with the spin-off, our Board adopted, and WDC as our then-sole stockholder approved, our 2025 Employee Stock Purchase Plan (the “2025 ESPP”), which became effective upon the consummation of the spin-off. The following summary is qualified in its entirety by the full text of the 2025 ESPP, which is included as Exhibit 10.34 to the registration statement on Form S-1 of which this prospectus forms a part.

Purpose

The purpose of the 2025 ESPP is to provide an incentive for present and future eligible employees of our company and our participating subsidiaries to acquire a proprietary interest (or increase an existing proprietary interest) in our company through the purchase of common stock.

Operation of the 2025 ESPP

The 2025 ESPP operates in a series of periods referred to as “Offering Periods.” We will establish the duration of each Offering Period in advance of that Offering Period. However, an Offering Period may not be longer than 24 months. We may provide for a new Offering Period to start before an Offering Period in progress has ended, but no one participant may participate in more than one Offering Period at the same time.

On the first day of each Offering Period (referred to as the “Enrollment Date”), each eligible employee who has timely filed a valid election to participate in the 2025 ESPP for that Offering Period is granted an option to purchase shares of our common stock. Participants may designate in their election the percentage of their compensation to be withheld from their pay during that Offering Period for the purchase of stock under the 2025 ESPP. Participants’ contributions under the 2025 ESPP are credited to a bookkeeping account in their name. Participants generally may elect to terminate their contributions to the 2025 ESPP at any time during an Offering Period. Participants also generally may elect to increase or decrease the rate of their contributions to the 2025 ESPP up to four times in a calendar year. Amounts contributed to the 2025 ESPP constitute general corporate assets of our company and may be used for any corporate purpose.

An Offering Period may consist of one or more periods referred to as “Exercise Periods.” The last day of each Exercise Period is referred to as an “Exercise Date.” Each option granted under the 2025 ESPP for an Offering Period is automatically exercised on each Exercise Date that occurs within that Offering Period. The number of shares acquired by participants upon exercise of their option is determined by dividing the participant’s account balance under the 2025 ESPP as of the Exercise Date by the Exercise Price for that Offering Period. We establish the methodology for setting the Exercise Price in an Offering Period in advance of that Offering Period. The administrator of the 2025 ESPP may set the Exercise Price at any price, except that in no event may the Exercise Price be lower than the lesser of (i) 85% of the fair market value of a share of our common stock on the applicable Enrollment Date, or (ii) 85% of the fair market value of a share of our common stock on the applicable Exercise Date. Participant accounts are reduced upon exercise of their options by the amount used to pay the Exercise Price of the shares acquired by the participant. No interest is paid to any participant or credited to any account under the 2025 ESPP.

##### Table of Contents

Eligibility

Only certain employees are eligible to participate in the 2025 ESPP. To be eligible to participate in an Offering Period, on the Enrollment Date of that period an individual must:

| • |  | be employed by our company or one of our subsidiaries that has been designated as a participating subsidiary; and

| • |  | be customarily employed for more than twenty hours per week and more than five months in a calendar year.

An employee who is a citizen or resident of a foreign jurisdiction to whom the grant of an option under the 2025 ESPP would be prohibited under the laws of such foreign jurisdiction, or compliance with the laws of such foreign jurisdiction would cause the 2025 ESPP to violate the requirements of Section 423 of the Internal Revenue Code, would not be eligible to participate in the 2025 ESPP. Section 16 officers are also not eligible to participate in the 2025 ESPP.

Limits on Authorized Shares; Limits on Contributions

A total of 4,345,891 shares are available for issuance under the 2025 ESPP.

Participation in the 2025 ESPP is also subject to the following limits:

| • |  | Participants cannot contribute more than 10% of their compensation to the purchase of stock under the 2025 ESPP in any one payroll period.

| • |  | Participants cannot be granted an option under the 2025 ESPP for an offering period with respect to a number of shares of our common stock that exceeds five times the number of shares determined by dividing (i) $40,000 by (ii) the fair market value of a share of our common stock on the Enrollment Date multiplied by 85% (or the applicable percentage used to calculate the Exercise Price for that offering period).

| • |  | Participants cannot purchase more than $25,000 of stock (valued at the start of the applicable Offering Period and without giving effect to any discount reflected in the purchase price for the stock) under the 2025 ESPP for each calendar year in which such option is outstanding.

| • |  | Participants will not be granted an option under the 2025 ESPP if it would cause the participant to own stock and/or hold outstanding options to purchase stock representing 5% or more of the total combined voting power or value of all classes of stock of our company or one of our subsidiaries or to the extent it would exceed certain other limits under the Internal Revenue Code.

Our company has the flexibility to change the 10% contribution limit referred to above and the maximum limit on the number of shares that may be acquired by any individual during an Offering Period or Exercise Period under the 2025 ESPP referred to above from time to time without stockholder approval. However, we cannot increase the aggregate number of shares available for delivery under the 2025 ESPP without stockholder approval, other than to reflect stock splits and similar adjustments as described below. The $25,000 and the 5% ownership limitations referred to above are required under the Internal Revenue Code.

Adjustments

The number and kind of shares available under the 2025 ESPP, as well as purchase prices and share limits under the 2025 ESPP, are subject to adjustment in the case of certain corporate events. These events include reclassifications, recapitalizations, stock splits (including a stock split in the form of a stock dividend) or reverse stock split, mergers, combinations, consolidations, other reorganization, spin-off, split-up, similar extraordinary dividend distribution in respect of our common stock, exchange of common stock or other securities of our company, or other similar, unusual or extraordinary corporate events in respect of our common stock.

##### Table of Contents

Termination of Participation

A participant’s election to participate in the 2025 ESPP will generally continue in effect for all Offering Periods until the participant files a new election that takes effect or the participant ceases to participate in the 2025 ESPP. A participant’s participation in the 2025 ESPP generally will terminate if, prior to the applicable Exercise Date, the participant ceases to be employed by our company or one of our participating subsidiaries or the participant is no longer scheduled to work more than twenty hours per week or more than five months in a calendar year. If a participant’s participation in the 2025 ESPP terminates during an Offering Period for any of the reasons discussed in the preceding paragraph, he or she will no longer be permitted to make contributions to the 2025 ESPP for that Offering Period and, subject to limited exceptions, his or her option for that Offering Period will automatically terminate and his or her account balance will be paid to him or her in cash without interest. However, a participant’s termination from participation will not have any effect upon his or her ability to participate in any succeeding Offering Period, provided that the applicable eligibility and participation requirements are again then met.

Transfer Restrictions

Participants rights with respect to options or the purchase of shares under the 2025 ESPP, as well as contributions credited to their accounts, may not be transferred, assigned, pledged or otherwise disposed of in any way except by will or the laws of descent and distribution.

Administration

The 2025 ESPP is administered by our Board or by a committee appointed by our Board. Our Board has appointed the Sandisk Compensation and Talent Committee as the administrator of the 2025 ESPP. The administrator has full power and discretion to adopt, amend or rescind any rules and regulations for carrying out the 2025 ESPP, to determine which (if any) of our company’s subsidiaries may be participating subsidiaries whose employees may participate in the 2025 ESPP, and to construe and interpret the 2025 ESPP. The administrator also may adopt rules, procedures or sub-plans applicable to particular subsidiaries or locations (for example and without limitation, as to participants employed in a particular jurisdiction outside of the U.S. who are subject to other applicable laws and regulations), which sub-plans may be designed to be outside of the scope of Section 423 of the Internal Revenue Code and need not comply with the otherwise applicable provisions of the 2025 ESPP. Decisions of the administrator with respect to the 2025 ESPP are final and binding on all persons.

No Limit on Other Plans

The 2025 ESPP does not limit the ability of our Board or any committee of our Board to grant awards or authorize any other compensation, with or without reference to our common stock, under any other plan or authority.

Amendments

Our Board generally may amend or suspend the 2025 ESPP at any time and in any manner. No amendment, suspension or termination of the 2025 ESPP may have a material adverse effect on the then-existing rights of any participant during an Exercise Period without the participant’s written consent, but our Board may amend, suspend or terminate the 2025 ESPP as to any outstanding options granted under the 2025 ESPP for an Offering Period, effective as of any Exercise Date within that Offering Period, without the consent of the participants to whom such options were granted. Stockholder approval for an amendment to the 2025 ESPP will only be required to the extent required by law or applicable stock exchange rules, or as necessary to meet the requirements of Section 423 of the Internal Revenue Code in order to preserve the intended tax consequences of the 2025 ESPP.

130

##### Table of Contents

Termination

Our Board may terminate the 2025 ESPP at any time. The 2025 ESPP will also terminate earlier if all of the shares authorized under the 2025 ESPP have been purchased.

Specific Benefits under the 2025 ESPP

The benefits that will be received by or allocated to eligible employees under the 2025 ESPP cannot be determined at this time because whether an eligible employee will participate, and the amount of contributions set aside to purchase shares of our common stock under the 2025 ESPP (subject to the limitations discussed above) as to an eligible employee who elects to participate in the 2025 ESPP, is entirely within the discretion of each individual participant.

Sandisk Deferred Compensation Plan

Our named executive officer is eligible to participate in our deferred compensation plan, which generally mirrors the WDC Deferred Compensation Plan. Our executive officers and certain other key employees who are subject to U.S. federal income taxes are eligible to participate in our deferred compensation plan. Participants are able to elect to defer certain compensation without regard to the tax code limitations applicable to tax-qualified plans. Under the plan, each participant may elect to defer up to 80% of his or her eligible compensation that may be earned during the following year. Amounts may be deferred until a specified date, disability or death. Emergency hardship withdrawals will also be permitted under the plan.

Sandisk Executive Severance Plan

Our named executive officer is eligible to participate in our executive severance plan (the “Sandisk Executive Severance Plan”), which generally mirrors WDC’s executive severance plan.

The Sandisk Executive Severance Plan is administered by the Sandisk Compensation and Talent Committee. Each NEO has been designated by the Sandisk Compensation and Talent Committee as a “Tier 1 Executive” under the Sandisk Executive Severance Plan. An executive who participates in the Sandisk Executive Severance Plan will receive the following severance benefits in the event the Company terminates the executive’s employment without cause (other than in anticipation of, or within 12 months following, a change in control that would entitle the executive to greater benefits under the Sandisk CIC Severance Plan (as defined below)):

| (i) | a lump sum payment equal to the executive’s monthly base salary multiplied by 24;

| (ii) | a lump sum payment for any incentive that was earned through a prior incentive cycle but has not yet been paid;

| (iii) | a lump sum payment equal to a pro-rata portion of the executive’s incentive opportunity for the incentive cycle in which the executive’s date of termination occurs (determined based on the number of days in the applicable incentive cycle during which the executive was employed and assuming 100% of the performance goals are achieved regardless of performance);

| (iv) | for RSUs, accelerated vesting of a prorated number of RSUs;

| (v) | for PSUs, a pro-rata portion of the target number of PSUs subject to the award will remain outstanding and eligible to vest, if at all, based on actual achievement of the performance goals over the performance period;

| (vi) | outplacement services provided by a vendor chosen by the Company and at the Company’s expense for 12 months following the executive’s termination of employment; and

131

##### Table of Contents

| (vii) | a lump sum payment equal to the applicable COBRA premium rate for Company-provided medical, dental and/or vision coverage existing as of the executive’s termination date multiplied by 18 months, payable in a lump sum cash payment.

Payment of severance benefits under the Sandisk Executive Severance Plan is conditioned upon the executive’s execution of a valid and effective release of claims. In addition, no executive is entitled to a duplication of benefits under the Sandisk Executive Severance Plan and any other severance plan, including the Sandisk CIC Severance Plan (as defined below).

Sandisk Change in Control Severance Plan

Our named executive officer is eligible to participate in the Sandisk CIC Severance Plan, which generally mirrors WDC’s change in control severance plan, unless otherwise determined by the Sandisk Board of Directors.

The Sandisk CIC Severance Plan provides the following benefits upon a termination of employment by the Company or by the executive for good reason, in either case, within 12 months following a change in control or within 6 months prior to a change in control (such 18-month period, the “change in control period”):

| (i) | a lump sum payment equal to two times the sum of (A) the participant’s annual base compensation plus (B) the target incentive opportunity under the incentive program under which the participant participates for the incentive cycle in which the date of termination occurs, plus (C) the participant’s annual car allowance (in each case, based on the rates as in effect immediately prior to the change in control or as in effect on the date of notice of termination of the executive’s employment, whichever is higher);

| (ii) | a payment for any incentive that was earned through a prior incentive cycle but has not yet been paid;

| (iii) | 100% vesting of any unvested outstanding time-based equity awards;

| (iv) | with respect to any PSU for which the applicable performance period has not ended as of the date of the participant’s termination of employment or the change in control (whichever occurs later), the number of shares of common stock of the Company that vest will be equal to the greater of: (x) the target number of shares of common stock of the Company subject to the award; or (y) the number of shares of common stock of the Company subject to that award that would vest based on the treatment set forth in the definitive agreement providing for the change in control with PSUs vesting at the target level of performance (or such greater level as provided in the definitive agreement providing for the change in control). Any credited dividend equivalent rights will also become proportionally vested;

| (v) | with respect to any such award for which the applicable performance period has ended as of the date of the participant’s termination of employment or the change in control (whichever occurs later), vesting will be based on the actual achievement of the applicable performance goal(s); and

| (vi) | a lump sum payment equal to the applicable COBRA premium payments (as reasonably determined by the Sandisk Compensation and Talent Committee) that would be payable by the participant to continue the participant’s company-provided medical, dental and/or vision coverage existing as of the participant’s termination date for a period of 24 months following such participant’s termination of employment. For purposes of clarity, such cash payment will be made regardless of whether the participant actually elects coverage under COBRA and will be determined as of the participant’s termination of employment and not impacted by, or adjusted for, events occurring after such date (including, without limitation, changes in coverage or premiums).

Any health and welfare benefits will be reduced to the extent of the receipt of substantially equivalent coverage by the executive from any successor employer. The Board or the Sandisk Compensation and Talent Committee may amend, suspend and/or terminate the Sandisk CIC Severance Plan at any time in its discretion, except during a change in control period or with respect to a participant who is already entitled to payment under the Sandisk CIC Severance Plan.

132

##### Table of Contents

Commencing on the date a change in control occurs and for 12 months thereafter (or for such shorter period of time as the participant remains employed following such change in control), the Sandisk CIC Severance Plan provides that executives will receive the following from the Company upon a change in control and for so long as they are employed thereafter: (i) a salary that is at least equal to the salary provided prior to the change in control; (ii) participation in and benefits under employee benefit plans or arrangements made available to executives of the Company generally; and (iii) reimbursement for all reasonable travel or other business expenses.

If the payments and benefits provided to an executive constitutes “parachute payments” within the meaning of Section 280G of the Internal Revenue Code and are subject to the excise tax imposed by section 4999 of the Internal Revenue Code (the “Excise Tax”), then the payments and benefits will be either (i) reduced (but not below zero) so that the present value of such total payments and benefits will be $1.00 less than three times the executive’s “base amount” (within the meaning of Section 280G of the Internal Revenue Code) and no portion will be subject to the Excise Tax or (ii) paid in full, whichever produces the better net after-tax position to the executive (taking into account any applicable Excise Tax and any other applicable taxes).

Offer Letters

Luis Felipe Visoso

WDC entered into an offer letter with Mr. Visoso, dated July 1, 2024, to serve as its Executive Vice President and Chief Administrative Officer. The offer letter provided for Mr. Visoso’s employment with WDC to transfer to Sandisk and for Mr. Visoso to serve as Chief Financial Officer of Sandisk following the spin-off. The offer letter provides for at-will employment. The offer letter provides that Mr. Visoso’s initial base salary is $825,000 and that during his employment with WDC, he was eligible to participate in the WDC Executive Short-Term Incentive Plan, with an individual target award of 150% of his eligible wages earned during the performance period.

In addition to a sign-on RSU award with a target value of $20,000,000 that vests with respect to one half of the award on each of the first two anniversaries of the date of grant, Mr. Visoso was also eligible to receive a fiscal 2025 award under the WDC 2021 Long-Term Incentive Plan with a target value of $10,000,000 consisting of 100% RSUs (the “2025 LTI Award”).

The offer letter further provides that if Mr. Visoso’s employment with Sandisk terminates without “cause” (as defined in the Sandisk CIC Severance Plan (as defined below)), any then-unvested portion of the sign-on RSU award and 2025 LTI Award will vest pro-rata based on his service.

The offer letter additionally provides that Mr. Visoso is eligible to receive a sign-on cash award of $7,150,000, with $4,000,000 payable within 30 days of his start date and $3,150,000 payable within 30 days of the six-month anniversary of his start date. The offer letter provides that if Mr. Visoso’s employment with Sandisk terminates prior to the second anniversary of his start date, any portion of the sign-on cash award received prior to such termination will be subject to repayment, and Mr. Visoso will forfeit any unpaid portion of such award. The offer letter further provides that notwithstanding the foregoing, Mr. Visoso will not be required to repay the sign-on cash award if his employment is terminated without “cause” (as defined in the Sandisk Executive Severance Plan) and he provides a satisfactory release of claims to Sandisk.

The offer letter provides that as a condition of his employment, Mr. Visoso is required to sign an Employee Inventions and Confidentiality Agreement governing inventions, proprietary information and such other subject matter, which we consider vital to protect our operations.

(3) | Reflects the portion of a PSU award that has been credited based on achievement of the performance goals but remained subject to a service requirement through August 27, 2024.

(4) | Reflects a PSU award granted by WDC. The numbers above reflect payment at target level, which is 100% of the target number of stock units of the full award, based on the trending performance as of the end of fiscal 2024. Because the performance metrics for fiscal 2025 was not set as of the end of fiscal 2024, the numbers above reflect the trending performance based solely on achievement of the fiscal 2023 and 2024 targets. In connection with the separation, this award was converted to time-based Sandisk RSUs, assumed under the Sandisk 2025 Long-Term Incentive Plan and is no longer subject to performance-based vesting conditions. This award is scheduled to vest on August 20, 2025.

(5) | Reflects a PSU award granted by WDC. The numbers above reflect payment at maximum performance, which is 220% of the target number of stock units of the full award, based on the trending performance as of the end of fiscal 2024. Because the performance metrics for fiscal 2025 and 2026 were not set during fiscal 2024, the numbers above reflect the trending performance based solely on achievement of the fiscal 2024 targets. In connection with the separation, this award was converted to time-based Sandisk RSUs, assumed under the Sandisk 2025 Long-Term Incentive Plan and is no longer subject to performance-based vesting conditions. This award is scheduled to vest on August 25, 2026.

Fiscal 2024 Non-Qualified Deferred Compensation

WDC permits its named executive officers and other key employees to elect to receive a portion of their compensation reported in the “Fiscal 2024 Summary Compensation Table” on a deferred basis under the WDC Deferred Compensation Plan. Under the plan, each participant may elect to defer up to 80% of his or her eligible compensation that may be earned during the following year. Amounts may be deferred until a specified date, retirement, disability or death. Emergency hardship withdrawals are also permitted under the plan. In connection with the separation, Sandisk has also adopted a Deferred Compensation Plan, which generally mirrors the terms of the WDC Deferred Compensation Plan. No amounts were contributed by Mr. Goeckeler to, and Mr. Goeckeler had no investment earnings, distributions or balance under, the WDC Deferred Compensation Plan during 2024.

Potential Payments upon Termination or Change in Control

Change in Control—Termination without Cause or For Good Reason

As discussed above, our named executive officers may be entitled to severance benefits under the Sandisk CIC Severance Plan which generally mirrors WDC’s change in control severance plan (the “WDC CIC Severance Plan”). Under the WDC CIC Severance Plan, the severance benefits are payable if WDC terminates 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 WDC stock, certain majority changes in its 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 its ownership, and certain liquidations and dissolutions of WDC

| • |  | “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 WDC 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 WDC (or its successor) with respect to its obligations under the WDC CIC Severance Plan

135

##### Table of Contents

Under the WDC CIC Severance Plan, the severance benefits for named executive officers 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

As discussed above, our named executive officers may be entitled to severance benefits under the Sandisk Executive Severance Plan which generally mirrors WDC’s executive severance plan (the “WDC Executive Severance Plan”). The WDC Executive Severance Plan provides the following severance benefits to its 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 at 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 the WDC CIC Severance Plan and the WDC 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 the WDC Executive Severance Plan and any other severance plan, including the WDC CIC Severance Plan.

Qualified Retirement

In the event a WDC executive officer meets certain retirement criteria, 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. There is no corresponding benefit for RSUs upon a qualified retirement.

To be eligible for retirement, the executive officer must have five years of credited service with WDC 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.

##### Table of Contents

Death

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

Termination for Cause/Misconduct

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

Calculation of Potential Payments upon Termination or Change in Control

The table below presents WDC’s estimate of the benefits payable to Mr. Goeckeler, under the arrangements described above based on the following assumptions:

| • |  | Qualifying termination of employment and/or change in control occurred on June 28, 2024

| • |  | The price per share of WDC common stock is equal to the closing price of WDC’s common stock on June 28, 2024 ($75.77), the last trading day in fiscal 2024

| • |  | In the case of a change in control, WDC 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 Mr. Goeckeler earned or accrued prior to termination, such as the balances under the WDC Deferred Compensation Plan and previously vested equity and non-equity incentive awards, which are more fully described and quantified in the tables and narratives above

(1) | Mr. Goeckeler’s equity awards will not 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 WDC’s incentive compensation plans in connection with a change in control as if it occurred on June 28, 2024 (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 WDC Compensation and Talent Committee had not provided for the assumption, substitution or other continuation of the awards.

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

(3) | As of June 28, 2024, Mr. Goeckeler did not meet the requirements for a “qualified retiree” with respect to PSUs.

(4) | The amounts shown are based on the intrinsic value of the portion of the RSU award that would have accelerated as of June 28, 2024. These intrinsic values were based on the closing price of WDC’s common stock on June 28, 2024 ($75.77).

(5) | The amounts shown represent the target number of PSUs subject to the award that would have remained outstanding and eligible to vest in connection with the termination event and are based on the intrinsic value of those stock units as of June 28, 2024. These intrinsic values were calculated by multiplying (i) the closing price of WDC’s common stock on June 28, 2024 ($75.77), 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 28, 2024.

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

Reconciliation of WDC Non-GAAP Financial Measures Used for Incentive Compensation

WDC’s Compensation and Talent Committee used non-GAAP operating income as a pre-established performance goal under the STI plan for fiscal 2024 and non-GAAP diluted income per common share (which we also refer to as non-GAAP EPS) as a pre-established performance goal under the fiscal 2022-2024, fiscal 2023-2025 and fiscal 2024-2026 PSU awards. In accordance with the pre-established terms of the STI and PSU awards, these non-GAAP performance measures excluded certain material or unusual items that WDC believes are not indicative of the underlying performance of its business as detailed below. 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. 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.

Explanations of Adjustments to Non-GAAP Measures

As detailed above, WDC excludes the following items from its non-GAAP financial measures:

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

Litigation matter. WDC accrues expenses in the fiscal fourth quarter associated with a recent judgment in a patent litigation matter, which is discussed more fully in WDC’s Annual Report on Form 10-K filed with the SEC on August 20, 2024. WDC believes these charges do not reflect its operating results and that they are not indicative of the underlying performance of its business.

Employee termination, asset impairment and other charges. From time-to-time, in order to realign its operations with anticipated market demand or to achieve cost synergies from the integration of acquisitions, WDC may terminate employees and/or restructure its operations. From time-to-time, WDC may also incur charges from the impairment of intangible assets and other long-lived assets. In addition, WDC may record credits related to gains upon sale of property due to restructuring or reversals of charges recorded in prior periods. In addition, in fiscal 2024, WDC has taken 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 WDC believes they are not indicative of the underlying performance of its business.

Business separation cost. WDC incurred expenses associated with this separation of its HDD and Flash business units to create two independent, public companies. WDC believes these charges do not reflect its operating results and that they are not indicative of the underlying performance of its business.

Amortization of acquired intangible assets. WDC incurs expenses from the amortization of acquired intangible assets over their economic lives. Such charges are significantly impacted by the timing and magnitude of WDC’s acquisitions and any related impairment charges.

Contamination related charges. In February 2022, a contamination of certain materials used in WDC’s manufacturing process occurred and affected production operation at the flash-based memory manufacturing facilities in Yokkaichi and Kitakami, Japan, which are operated through its joint business ventures with Kioxia. The contamination resulted in scrapped inventory and rework costs, decontamination and other costs needed to restore the facilities to normal capacity, and under absorption of overhead costs, which are expensed as incurred. These charges are inconsistent in amount and frequency, and WDC believes these charges are not part of the ongoing production operation of its business.

Recovery from contamination incident. In February 2022, a contamination of certain materials used in WDC’s manufacturing process occurred and affected production operations at the flash-based memory manufacturing facilities in Yokkaichi and Kitakami, Japan, which are operated through its joint business ventures with Kioxia. The contamination resulted in scrapped inventory and rework costs, decontamination and other costs needed to restore the facilities to normal capacity, and under absorption of overhead costs which were expensed as incurred. During the quarters ended December 29, 2023, and March 29, 2024, WDC received recoveries of these losses from other parties. The contamination charges and related recoveries were inconsistent in amount and frequency, and WDC believes they were not part of the ongoing production operation of its business.

Recovery related to a power outage incident. In June 2019, an unexpected power outage incident occurred at the flash-based memory manufacturing facilities operated through WDC’s joint venture with Kioxia in Yokkaichi, Japan. The power outage incident resulted in costs associated with the repair of damaged tools and the write-off of damaged inventory and unabsorbed manufacturing overhead costs which are expensed as incurred. During fiscal 2021 and 2022, WDC received recoveries of these losses from other parties. The recoveries are inconsistent in amount and frequency, and WDC believes they are not part of the ongoing production operation of its business.

Strategic review. WDC incurred expenses associated with its review of strategic alternatives that resulted in the planned separation of its HDD and Flash business units to create two independent, public companies. WDC believes these charges do not reflect its operating results and that they are not indicative of the underlying performance of its business.

Non-cash economic interest. WDC have excluded non-cash economic interest expense associated with its convertible notes recognized in periods prior to its adoption of the Financial Accounting Standards Board Accounting Standards Update No. 2020-06, “Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity,” which WDC adopted at the beginning of its fiscal year ending June 30, 2023. The exclusion of such amounts from prior periods facilitates a comparison of WDC’s prior period results to the current period presentation.

Other adjustments. From time-to-time, WDC sells or impairs investments or other assets which are not considered necessary to its business operations or incur other charges or gains that WDC believes are not a part of the ongoing operation of its business. The resulting expense or benefit is inconsistent in amount and frequency.

Income tax adjustments. Income tax adjustments include the difference between income taxes based on a forecasted annual non-GAAP tax rate and a forecasted annual GAAP tax rate as a result of the timing of certain non-GAAP pre-tax adjustments. The income tax adjustments also include adjustments to estimates related to the current status of the rules and regulations governing the transition to the Tax Cuts and Jobs Act and the re-measurement of certain unrecognized tax benefits primarily related to tax positions taken in prior periods, including interest. These adjustments are excluded because WDC believes that they are not indicative of the underlying performance of its ongoing business.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

Material Agreements with WDC

With the spin-off completed, WDC and Sandisk are now separate independent companies. WDC owns 19.9% of our common stock and will own such shares of our common stock for a period of up to 12 months following the distribution. The current relationship between WDC and Sandisk is governed by certain ancillary agreements WDC and Sandisk entered into in connection with the spin-off. These agreements provide for the allocation between Sandisk and WDC of WDC’s and Sandisk’s assets, employees, liabilities and obligations (including employee benefits and tax-related assets and liabilities) attributable to periods prior to, at and after Sandisk’s spin-off from WDC.

The material agreements described below are filed as exhibits to the registration statement on Form S-1, of which this prospectus forms a part, and the summaries below set forth the terms of the agreements that Sandisk believes are material. These summaries are qualified in their entireties by reference to the full text of the applicable agreements, which are incorporated by reference into this prospectus.

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. It 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.

Transfer of Assets and Assumption of Liabilities. The separation and distribution agreement identifies assets to be transferred to or retained by, liabilities to be assumed or retained by, and contracts to be assigned to each of Sandisk and WDC as part of the reorganization of WDC, and describes when and how these transfers, assumptions and assignments would occur, although many of the transfers, assumptions and assignments had already occurred prior to the parties’ entering into the separation and distribution agreement. In particular, the separation and distribution agreement provides that, subject to the terms and conditions contained in the separation and distribution agreement:

| • |  | All assets constituting “Flash Assets” are retained by or transferred to Sandisk or one of our subsidiaries. Flash Assets consist of, among other things, assets primarily related to the Flash Business (except as otherwise set forth in the separation and distribution agreement), all rights to causes of action to the extent related to the Flash Business or any assets or liabilities allocated to Sandisk and certain owned and leased real properties designated as Flash Assets. All other assets of WDC that are not Flash Assets were retained by or transferred to WDC. These retained assets include, among others, certain owned and leased real property and all rights to causes of action to the extent that they do not relate to the Flash Business or any assets or liabilities allocated to Sandisk. WDC may reduce the amount of cash and cash equivalents in Sandisk and its subsidiaries in excess of $1,339 million at the time of the distribution.

| • |  | WDC’s transfer to Sandisk, and Sandisk’s assumption of, certain liabilities, whether arising prior to, at or after the distribution, regardless of when and where such liabilities arose or where, or against whom, such liabilities are asserted or determined, including, among others, liabilities to the extent relating to the conduct and operation of the Flash Business and/or the ownership, operation or use of any Flash Assets (other than liabilities of a business that has been divested or discontinued prior to the distribution) and certain environmental liabilities arising from owned or leased real properties designated as Flash Assets. WDC retained all liabilities not assumed by Sandisk.

| • |  | Except as otherwise provided in the separation and distribution agreement or any ancillary agreement, WDC is responsible for all costs and expenses incurred on or prior to the distribution by WDC or

142

##### Table of Contents

| Sandisk in connection with the preparation, execution, delivery and implementation of the separation and distribution agreement or any ancillary agreement, and each party will bear its own direct and indirect costs and expenses incurred from and after the distribution in connection with the preparation, execution, delivery and implementation of the separation and distribution agreement or any ancillary agreement.

The allocation of liabilities with respect to taxes, except for payroll taxes and reporting and other tax matters expressly covered by the employee matters agreement, are solely covered by the tax matters agreement.

Except as may expressly be set forth in the separation and distribution agreement or any ancillary agreement, all assets are transferred on an “as is,” “where is” basis and the respective transferees bear the economic and legal risks that any conveyance proves to be insufficient to vest in the transferee good title, free and clear of any security interest, that any necessary consents or governmental approvals are not obtained, and that any requirements of laws or judgments are not complied with.

Information in this prospectus with respect to the assets and liabilities of the parties following the separation is presented based on the allocation of such assets and liabilities pursuant to the separation and distribution agreement, unless the context otherwise requires. Certain of the liabilities and obligations to be assumed by one party or for which one party has an indemnification obligation under the separation and distribution agreement and the other agreements relating to the separation are and continue to be the legal or contractual liabilities or obligations of another party. Each such party that continues to be subject to such legal or contractual liability or obligation relies on the applicable party that assumed the liability or obligation or the applicable party that undertook an indemnification obligation with respect to the liability or obligation, as applicable, under the separation and distribution agreement, to satisfy the performance and payment obligations or indemnification obligations with respect to such legal or contractual liability or obligation.

Releases and Indemnifications. Except as otherwise provided in the separation and distribution agreement or any ancillary agreement, each party releases and forever discharges the other party and its subsidiaries and affiliates and all persons who are or have been stockholders, directors, partners, managers, managing members, officers, agents or employees of the other party or any of their respective subsidiaries, as applicable (in each case, in their respective capacities as such) (excluding any shareholder of WDC or Sandisk) (the “Indemnified Parties”), from all liabilities existing or arising from any acts or events occurring or failing to occur or alleged to have occurred or to have failed to occur or any conditions existing or alleged to have existed on or before the distribution, whether or not known as of the distribution, including in connection with the transactions and all other activities to implement the separation or the distribution. The releases do not extend to obligations from and after the separation under or relating to any agreement between the parties that did not terminate as of the distribution. In addition, the separation and distribution agreement provides for cross-indemnities that, except as otherwise provided in the separation and distribution agreement, are principally designed to place financial responsibility for the obligations and liabilities of the Flash Business with Sandisk and financial responsibility for the obligations and liabilities of WDC’s business with WDC. Specifically, each party will, and will cause its subsidiaries to, indemnify, defend and hold harmless the other party and the applicable Indemnified Parties for any loss that proximately results from:

| • |  | the liabilities each such party assumed or retained pursuant to the separation and distribution agreement, including failure of a party to pay, perform or otherwise promptly discharge any liability assumed or retained, as applicable, pursuant to the separation and distribution agreement in accordance with their respective terms; and

| • |  | any breach of, or failure to perform, by such party or its subsidiaries of any covenants or obligations to be performed from and after the separation by such persons pursuant to the separation and distribution agreement or any ancillary agreement, unless such ancillary agreement expressly provides for separate indemnification therein, in which case any such indemnification claims will be made thereunder.

143

##### Table of Contents

Each party’s aforementioned indemnification obligations are uncapped, provided that the amount of each party’s indemnification obligations are subject to reduction by any insurance proceeds (net of premium increases) received by the party being indemnified. The separation and distribution agreement also specifies procedures with respect to claims subject to indemnification and related matters. Indemnification with respect to taxes will be governed solely by the tax matters agreement.

Insurance. Sandisk generally is responsible for obtaining and maintaining Sandisk’s own insurance coverage and is no longer an insured party under WDC’s insurance policies following the separation.

Non-Compete. Under the separation and distribution agreement, and subject to certain exceptions, for a period of forty (40) months following the separation, WDC will not develop, manufacture, market or sell standalone SSDs.

Dispute Resolution. Subject to certain exceptions, if a dispute arises with WDC out of, in connection with, or in relation to the separation and distribution agreement or any ancillary agreement or the transactions contemplated thereby, then such representatives, as the parties may designate, will negotiate to resolve any disputes for a period of time not exceeding thirty (30) days. If the parties are unable to resolve the dispute in this manner, either party may demand that the dispute be brought and determined exclusively in the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware for final determination.

Other Matters Governed by the Separation and Distribution Agreement. Other matters governed by the separation and distribution agreement include 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.

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, in each case, for a transitional period after the closing of the spin-off to provide for an ordinary transition in connection with the spin-off. The TSA specifies the terms under which the transition services are provided, including the services standard, fees and allocation of risk, and contains mechanisms for adding, extending and terminating services as well as for governance and dispute resolution. The charges for such services are generally intended to allow the service provider to recover its direct and indirect costs, generally without profit. Services are anticipated to be provided in the following areas: (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 eighteen (18) months.

Tax Matters Agreement

In connection with the spin-off, WDC and Sandisk entered into a tax matters agreement that governs the parties’ respective rights, responsibilities and obligations with respect to tax liabilities and benefits, tax attributes, the preparation and filing of tax returns, the control of audits and other tax proceedings and other matters regarding taxes.

The tax matters agreement provides special rules that allocate tax liabilities in the event the distribution or certain related transactions fails to qualify as transactions that are tax-free for U.S. federal income tax purposes (other than any cash that WDC stockholders receive in lieu of fractional shares). Under the tax matters agreement, Sandisk generally agreed to indemnify WDC and its affiliates against any and all tax-related liabilities incurred by them relating to the distribution and certain related transactions, to the extent caused by any representation by Sandisk being incorrect or an acquisition of our stock or assets or by any other action undertaken or by failure to act by Sandisk. This indemnification applies even if WDC has permitted Sandisk to take an action that would otherwise have been prohibited under the tax-related covenants described below.

144

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. Sandisk may take certain actions prohibited by these covenants only if Sandisk obtains and provides to WDC an opinion from a U.S. tax counsel or accountant of recognized national standing or a favorable private letter ruling from a taxing authority, in each case satisfactory to WDC, to the effect that such action would not affect the tax-free status of these transactions, or if Sandisk obtains prior written consent of WDC, in its sole and absolute discretion, waiving such requirement. Sandisk is barred from taking any action, or failing to take any action, including any action or failure to take any action that would be inconsistent with the Tax Opinion, where such action or failure to take any action adversely affects the tax-free status of these transactions. In addition, during the period ending two years after the date of the distribution, these covenants include specific restrictions on Sandisk: (i) discontinuing the active conduct of Sandisk’s trade or business; (ii) issuance or sale of stock or other securities (including securities convertible into Sandisk stock, but excluding certain compensatory arrangements); (iii) liquidating, merging or consolidating with any other person; (iv) amending Sandisk’s charter (or other organizational documents) or taking any other action, whether through a stockholder vote or otherwise, affecting the voting rights of Sandisk common stock; (v) sales of assets outside the ordinary course of business; and (vi) entering into any other corporate transaction which would cause Sandisk to undergo a 50% or greater change in its stock ownership or otherwise 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 spin-off 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 provides that, unless otherwise specified, each party assumes or retains, as applicable, liabilities arising out of or in connection with the employment or termination of the employees identified as WDC or Sandisk employees, as applicable, including under any employee benefit plans, whether arising before or after the distribution. Additionally, subject to certain exceptions, upon the distribution, each party has caused or will cause, as applicable, the employees identified as WDC or Sandisk employees, as applicable, to commence or continue participation in employee benefit plans, similar to those in effect on or prior to the date of the distribution and will recognize prior years of service with WDC and related entities.

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.

The employee matters agreement also contemplates cash transaction bonus payments in an aggregate amount of $39 million that is payable in connection with the spin-off to certain Sandisk employees in positions of vice president and above, which cash payments for each eligible individual are based on a number of months’ base salary, ranging from 12 months for vice president and equivalent titles to 24 months for executive vice presidents and Section 16 officers. The transaction bonus payments generally are subject to repayment terms for 12 months following the separation in the event of specified termination events.

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-spin. 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 (the “TTLA”), 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-spin, 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. Under the SRRA, Sandisk also agreed to use its reasonable best efforts to effect a shelf registration on Form S-1 for all shares of our common stock retained by WDC within thirty (30) days of the date of the spin-off. In addition, 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.

Sandisk is registering on a registration statement on Form S-1, of which this prospectus forms a part, the shares of our common stock retained by WDC pursuant to its obligations under the SRRA.

Other Related Party Transactions

Other than as described above, we have not had any related person transaction since our formation on February 5, 2024 in connection with the separation.

Procedures for Approval of Related Person Transactions

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

U.S. FEDERAL INCOME TAX CONSIDERATIONS FOR NON-U.S. HOLDERS

The following is a general summary of the material U.S. federal income considerations generally applicable to the ownership and disposition of our common stock by a Non-U.S. Holder (as defined below) that holds our common stock as a capital asset (generally, property held for investment). This discussion is based on the Code, U.S. Treasury regulations promulgated thereunder, judicial decisions, administrative pronouncements and other relevant applicable authorities, all as currently in effect as of the date hereof and all of which are subject to change or differing interpretations (possibly with retroactive effect). We have not sought and do not expect to seek any rulings from the IRS regarding the matters discussed below. There can be no assurance that the IRS will not take positions concerning the tax consequences of the ownership or disposition of shares of our common stock that differ from those discussed below.

This discussion does not describe all of the tax consequences that may be applicable to Non-U.S. Holders in light of their particular circumstances, or Non-U.S. Holders subject to special treatment under U.S. federal income tax law, such as:

| • |  | U.S. expatriates and certain former citizens or long-term residents of the United States;

| • |  | persons subject to an alternative minimum tax;

| • |  | persons holding our common stock as part of a hedge, straddle or other risk reduction strategy or as part of a conversion transaction or other integrated investment;

| • |  | banks, insurance companies and other financial institutions;

| • |  | real estate investment trusts or regulated investment companies;

| • |  | brokers, dealers or traders in securities;

| • |  | “controlled foreign corporations,” “passive foreign investment companies” and corporations that accumulate earnings to avoid U.S. federal income tax;

| • |  | persons owning (directly or indirectly) 5% or more of our common stock;

| • |  | tax-exempt organizations or governmental organizations;

| • |  | persons deemed to sell our common stock under the constructive sale provisions of the Code;

| • |  | persons who hold or receive our common stock pursuant to the exercise of any employee stock option or otherwise as compensation; and

| • |  | tax-qualified retirement plans.

In addition, this discussion does not address any U.S. state or local or non-U.S. tax considerations or any U.S. federal estate, gift, alternative minimum tax or Medicare contribution tax considerations. Non-U.S. Holders should consult their tax advisors regarding the particular tax considerations to them of owning and disposing of our common stock.

For purposes of this discussion, the term “Non-U.S. Holder” means a beneficial owner of our common stock that is not, for U.S. federal income tax purposes, a partnership (or entity or arrangement treated as a partnership) or any of the following:

| • |  | an individual who is a citizen or resident of the United States;

| • |  | a corporation that is created or organized under the laws of the United States, any state thereof or the District of Columbia;

| • |  | an estate the income of which is subject to U.S. federal income taxation regardless of its source; or

| • |  | a trust (A) if a court within the United States is able to exercise primary supervision over its administration and one or more “United States persons” (within the meaning of Section 7701(a)(30) of

147

##### Table of Contents

| the Code) have the authority to control all substantial decisions of such trust, or (B) that has made a valid election under applicable Treasury Regulations to be treated as a United States person.

If a partnership (or other entity treated as a partnership or other pass-through entity for U.S. federal income tax purposes) holds our common stock, the tax treatment of a partner or beneficial owner of the entity will generally depend on the status of the partner or beneficial owner and the activities of the entity. Partners in a partnership (or beneficial owners of another entity treated as a partnership or other pass-through entity for U.S. federal income tax purposes) should consult their tax advisors regarding the tax considerations of an investment in our common stock.

Distributions

As described in the section captioned “Dividend Policy,” we do not anticipate paying dividends to holders of our common stock in the foreseeable future.

In the event that we make distributions on our common stock, such distributions will generally be treated as dividends to the extent paid from our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). If a distribution exceeds our current and accumulated earnings and profits (as determined under U.S. federal income tax principles), the excess will be treated first as a return of capital to the extent of a Non-U.S. Holder’s adjusted tax basis in our common stock and thereafter as capital gain from the sale or exchange of our common stock, with the tax treatment described below in “Sale, Exchange or Other Disposition of Our Common Stock.”

Distributions treated as dividends paid on our common stock to a Non-U.S. Holder will generally be subject to U.S. federal withholding tax at a 30% rate of the gross amount of the dividends, or a reduced rate specified by an applicable income tax treaty. In order to obtain a reduced rate of withholding under an applicable income tax treaty, a Non-U.S. Holder will generally be required to provide a properly executed IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable, certifying its entitlement to benefits under the treaty. A Non-U.S. Holder eligible for a reduced rate of U.S. federal withholding tax pursuant to an income tax treaty may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

Subject to the discussion below under “—FATCA,” no amounts in respect of U.S. federal withholding tax will be withheld from dividends paid to a Non-U.S. Holder if the dividends are effectively connected with such Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, are attributable to a permanent establishment or fixed base maintained by such Non-U.S. Holder in the United States) and the Non-U.S. Holder provides a properly executed IRS Form W-8ECI. Instead, the effectively connected dividends will generally be subject to regular U.S. income tax on a net income basis as if the Non-U.S. Holder were a U.S. person as defined under the Code. A Non-U.S. Holder that is a treated as a corporation for U.S. federal income tax purposes receiving effectively connected dividends may also be subject to an additional “branch profits tax” imposed at a rate of 30% (or a lower treaty rate) on its effectively connected earnings and profits (subject to certain adjustments).

Sale, Exchange or Other Disposition of Our Common Stock

A Non-U.S. Holder will generally not be subject to U.S. federal income tax on gain realized on a sale, exchange or other disposition of our common stock unless:

| • |  | such gain is effectively connected with a trade or business conducted by such Non-U.S. Holder in the United States (and, if required by an applicable income tax treaty, is attributable to a permanent establishment maintained by such Non-U.S. Holder in the United States), in which case such gain will generally be subject to U.S. federal income tax in the same manner as effectively connected dividend income as described above;

148

##### Table of Contents

| • |  | such Non-U.S. Holder is an individual present in the United States for 183 days or more in the taxable year of disposition and certain other conditions are met, in which case such gain will generally be subject to U.S. federal income tax at a rate of 30% (or a lower treaty rate), which gain may be offset by certain U.S.-source capital losses even though the individual is not considered a resident of the United States; or

| • |  | we are or become a United States real property holding corporation (as defined in section 897(c) of the Code, a “USRPHC”), at any time within the shorter of the five-year period preceding the disposition or the Non-U.S. Holder’s holding period, and either (i) our common stock is not regularly traded on an established securities market prior to the beginning of the calendar year in which the sale or disposition occurs, or (ii) the Non-U.S. Holder has owned or is deemed to have owned, at any time within the shorter of the five-year period preceding the disposition or the Non-U.S. Holder’s holding period, more than 5% of our common stock.

Although there can be no assurances in this regard, we believe that we are not a USRPHC and we do not anticipate becoming a USRPHC for U.S. federal income tax purposes.

FATCA

Certain rules may require withholding at a rate of 30% on dividends in respect of our common stock held by or through certain foreign financial institutions (including investment funds), unless such institution (i) enters into, and complies with, an agreement with the Treasury to report, on an annual basis, information with respect to interests in, and accounts maintained by, the institution to the extent such interests or accounts are held by certain U.S. persons and by certain non-U.S. entities that are wholly or partially owned by U.S. persons and to withhold on certain payments or (ii) if required under an intergovernmental agreement between the United States and an applicable foreign country, reports such information to its local tax authority, which will exchange such information with the U.S. authorities. An intergovernmental agreement between the United States and an applicable foreign country may modify these requirements. Accordingly, the entity through which our common stock is held will affect the determination of whether such withholding is required. Similarly, dividends in respect of our common stock held by an investor that is a non-financial non-U.S. entity that does not qualify under certain exemptions will be subject to withholding at a rate of 30%, unless such entity either (i) certifies that such entity does not have any “substantial United States owners” or (ii) provides certain information regarding the entity’s “substantial United States owners,” which we or the applicable withholding agent will in turn provide to the IRS. Non-U.S. Holders should consult their tax advisors regarding the possible implications of this withholding tax on their investment in our common stock.

THIS DISCUSSION IS FOR INFORMATION PURPOSES ONLY AND IS NOT INTENDED AS TAX ADVICE. INVESTORS SHOULD CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF OUR COMMON STOCK ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL OR NON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

DESCRIPTION OF MATERIAL INDEBTEDNESS

The material agreements described below are filed as exhibits to the registration statement on Form S-1 of which this prospectus forms a part. The summaries of each of these agreements set forth below are qualified in their entireties by reference to the full text of the applicable agreements, which are incorporated by reference into this prospectus.

On February 21, 2025, Sandisk entered into the Loan Agreement. The Loan Agreement comprises the Facilities. The Term Loan Facility bears interest, at Sandisk’s option, at (x) the Adjusted Term SOFR Rate (as defined in the Loan Agreement) plus an interest rate margin of 3.00% per annum or (y) a base rate plus an interest rate margin of 2.00% per annum. The Term Loan Facility will mature on February 21, 2032, and amortizes at 1.00% per annum.

Borrowings under the Revolving Credit Facility, for U.S. dollar borrowings, bear interest, at Sandisk’s option, at (x) the Adjusted Term SOFR Rate (as defined in the Loan Agreement), which rate includes a credit spread adjustment of 0.10%, plus an interest rate margin of 2.00% per annum (subject to step-ups based on Sandisk’s Leverage Ratio (as defined in the Loan Agreement)), or (y) a base rate plus an interest rate margin of 1.00% per annum (subject to step-ups based on Sandisk’s Leverage Ratio (as defined in the Loan Agreement)). Sandisk will pay a commitment fee of 0.30% per annum (subject to step-ups based on Sandisk’s Leverage Ratio (as defined in the Loan Agreement)) in respect of undrawn revolving commitments under the Revolving Credit Facility. The Revolving Credit Facility also provides for borrowings in Euros, Yen and additional currencies agreed to by the lenders under the Revolving Credit Facility. The Revolving Credit Facility will mature on February 21, 2030, at which time the commitments thereunder shall be terminated, and will not have any amortization.

The obligations under the Loan Agreement are guaranteed by Sandisk’s wholly owned subsidiary, Sandisk Technologies, Inc. (“SDT”) and are required to be guaranteed by any of Sandisk’s future material U.S. wholly owned subsidiaries, subject to certain exceptions as outlined in the Loan Agreement. The obligations under the Loan Agreement are secured by Sandisk’s assets and SDT’s assets and are required to be secured by the assets of any of our future material U.S. wholly owned subsidiaries, subject, in each case, to certain exceptions outlined in the Loan Agreement.

The Loan Agreement includes certain restrictions (subject to certain exceptions outlined in the Loan Agreement) on the ability of Sandisk and its subsidiaries to undertake certain activities, including to incur indebtedness and liens, merge or consolidate with other entities, dispose or transfer their assets, pay dividends or make distributions, make investments, make payments on junior or subordinated debt, enter into burdensome agreements or transact with affiliates. The Loan Agreement also includes a financial covenant, which is solely for the benefit of the lenders under the Revolving Credit Facility, that requires Sandisk to maintain a maximum Leverage Ratio (as defined in the Loan Agreement).

On February 21, 2025, Sandisk borrowed $2.0 billion under its Term Loan Facility. Sandisk used a portion of the proceeds of the borrowing to pay a dividend to WDC in the amount of approximately $1.5 billion, with the remainder to be used for general corporate purposes of Sandisk. The Revolving Credit Facility may be borrowed by Sandisk from time to time for general corporate purposes. There were no amounts outstanding as of April 30, 2025 under the Revolving Credit Facility.

In connection with the Loan Agreement, Sandisk and SDT entered into a security agreement (the “Security Agreement”), to secure the obligations under the Facilities on a first-priority basis (subject to permitted liens) by a lien on substantially all the assets and properties of Sandisk and SDT, subject to certain exceptions.

In connection with the Loan Agreement, Sandisk (solely with respect to obligations of any additional Borrower under the Loan Agreement) and SDT entered into a guaranty agreement (the “Guaranty Agreement”) to secure and unconditionally guarantee the obligations under the Loan Agreement, respectively, in each case subject to certain exceptions.

For purposes of the table below, we have assumed all of the shares to be registered on this registration statement on Form S-1, of which this prospectus is a part, are sold in one offering. We will update the below table in the applicable prospectus supplement for any offering.

Security Ownership of Certain Beneficial Owners and Our Executive Officers and Directors

The following table reports the number of shares of our common stock that we believe are beneficially owned by each person who is believed to beneficially own more than 5% of our common stock.

DESCRIPTION OF SANDISK CORPORATION CAPITAL STOCK

Our certificate of incorporation and bylaws were amended and restated prior to the distribution. The following descriptions are summaries of the material terms of our current certificate of incorporation and our current bylaws that went in effect at the time of the distribution. These descriptions contain all information which we consider to be material but may not contain all of the information that is important to you. The summaries and descriptions below do not purport to be complete statements of the relevant provisions of our certificate of incorporation or of our bylaws and are qualified by reference to Delaware statutory and common law and the full texts of such documents. The summary is qualified in its entirety by reference to these documents, which you should read (along with the applicable provisions of Delaware law) for complete information on our capital stock. Our certificate of incorporation and our bylaws are included as exhibits to the registration statement on Form S-1, of which this prospectus forms a part.

General

Our authorized capital stock consists of

| • |  | 450,000,000 shares of common stock, par value $0.01 per share; and

| • |  | 10,000,000 shares of preferred stock, par value $0.01 per share.

As of April 30, 2025, 145,299,218 shares of our common stock were issued and outstanding and no shares of our preferred stock were issued and outstanding. The outstanding shares of common stock are duly authorized, validly issued, fully paid and non-assessable.

Common Stock

Subject to the relative rights, limitations and preferences of the holders of any then outstanding preferred stock, holders of our common stock are entitled to certain rights, including (i) to share ratably in dividends if, when and as declared by our Board of Directors out of funds legally available therefor and (ii) in the event of liquidation, dissolution or winding up of the Company, to share ratably in the distribution of assets legally available therefor, after payment of debts and expenses. Each outstanding share of our common stock entitles the holder to one vote on all matters submitted to a vote of the stockholders, including the election of directors, and the holders of shares of our common stock and our preferred stock (if any), collectively, possess the exclusive voting power. The holders of our common stock do not have cumulative voting rights in the election of directors or preemptive rights to subscribe for additional shares of our capital stock. Our bylaws require that, in uncontested elections, each director be elected by the majority of votes cast with respect to such director. This means that the number of shares voted “for” a director nominee must exceed the number of votes cast “against” that nominee in order for that nominee to be elected.

Holders of shares of our common stock have no preference, conversion, exchange, sinking fund, redemption or appraisal rights. The rights, preferences and privileges of holders of our common stock are subject to the terms of any series of preferred stock which Sandisk may issue in the future.

Preferred Stock

Our Board of Directors has the authority, within the limitations and restrictions that are stated in our certificate of incorporation, to authorize the issuance of shares of our preferred stock, in one or more classes or series, and to fix the rights, preferences, privileges and restrictions thereof, including dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences, preemptive rights and the number of shares constituting any series or the designation of such series. The issuance of our preferred stock could have the effect of decreasing the market price of our common stock and could adversely affect the voting and other rights of the holders of our common stock.

Our certificate of incorporation and our bylaws include provisions, summarized below, that are intended to discourage and prevent coercive takeover practices and inadequate takeover bids. These provisions are designed to encourage persons seeking to acquire control of the Company to first negotiate with our Board of Directors. They also are intended to provide our management with the flexibility to enhance the likelihood of continuity and stability if our Board of Directors determines that a takeover is not in the best interests of our stockholders. These provisions, however, could have the effect of discouraging others from making tender offers for our shares and may have the effect of deterring hostile takeovers or delaying changes in our control or management.

Special Stockholder Meetings

Our bylaws provide that only our Board of Directors, the Chair of the Board or our Chief Executive Officer may call special meetings of stockholders. Stockholders do not have the authority to call a special meeting of stockholders.

Requirements for Advance Notification of Stockholder Nominations and Proposals

Our bylaws provide that our stockholders must comply with advance notice procedures to bring business before or nominate directors for election at a meeting of stockholders. A stockholder (or group of up to 20 stockholders) who has held at least 3% of our common stock for at least three years must also satisfy and comply with additional requirements that are set forth in our bylaws to nominate and have any director nominee (generally not exceeding the greater of (i) two director nominees or (ii) 20% of the number of directors on our Board of Directors, rounded down to the nearest whole number) included in our proxy materials.

Elimination of Stockholder Action by Written Consent

The DGCL permits stockholder action by written consent unless the corporation’s certificate of incorporation provides otherwise. Our certificate of incorporation eliminates the right of stockholders to act by written consent without a meeting.

No Cumulative Voting

Under Delaware law, cumulative voting for the election of directors is not permitted unless a corporation’s certificate of incorporation authorizes cumulative voting. Our certificate of incorporation and our current bylaws do not provide for cumulative voting in the election of directors. The absence of cumulative voting makes it more difficult for a minority stockholder to gain a seat on our Board of Directors to influence our Board of Directors’ decision regarding a takeover.

Authorized but Unissued Shares

Subject to the requirements of Nasdaq and other applicable law, authorized but unissued shares of our common stock may be available for future issuance without stockholders’ approval. Sandisk may use these additional shares for a variety of corporate purposes, including future public offerings to raise additional capital, corporate acquisitions and employee benefit plans. The existence of authorized but unissued shares of our common stock could render more difficult or discourage an attempt to obtain control of Sandisk by means of a proxy contest, tender offer, merger or otherwise.

Amendment of Provisions in Certificate of Incorporation and Bylaws

Our certificate of incorporation provides that our certificate of incorporation may be amended in accordance with Delaware law. Our bylaws provide that our bylaws, or any of them, may be altered, amended or repealed, and

154

##### Table of Contents

new bylaws may be adopted, (i) by our Board of Directors, by vote of a majority of the number of directors then in office as directors, acting at any duly called and held meeting of our Board of Directors, or (ii) by the stockholders; provided that a notice of such proposed amendment, modification, repeal or adoption is given in the notice of special meeting.

Delaware Anti-Takeover Law

Sandisk Corporation is subject to Section 203 of the DGCL, which is an anti-takeover law. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a business combination with an interested stockholder for a period of three years following the date that the person became an interested stockholder, unless the business combination or the transaction in which the person became an interested stockholder is approved in a prescribed manner. Generally, a business combination includes a merger, asset or stock sale, or another transaction resulting in a financial benefit to the interested stockholder. Generally, an interested stockholder is a person who, together with affiliates and associates, owns 15% or more of the corporation’s voting stock. Under Section 203, a business combination between a corporation and an interested stockholder is prohibited unless it satisfies one of the following conditions:

| • |  | before the stockholder became interested, the board of directors approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;

| • |  | upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the voting stock outstanding, shares owned by persons who are directors and also officers, and employee stock plans, in some instances; or

| • |  | at or after the time the stockholder became interested, the business combination was approved by the board of directors of the corporation and authorized at an annual or special meeting of the stockholders by the affirmative vote of at least two-thirds of the outstanding voting stock which is not owned by the interested stockholder.

Exclusive Forum

Our certificate of incorporation provides that, unless Sandisk consents in writing to the selection of an alternative forum, (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our current or former directors, officers, other employees or stockholders to Sandisk or its stockholders, (iii) any action asserting a claim arising pursuant to any provision of the DGCL, or our certificate of incorporation or our bylaws or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware, or (iv) any action asserting a claim governed by the internal affairs doctrine of the law of the State of Delaware will, to the fullest extent permitted by law, be exclusively brought in the Court of Chancery of the State of Delaware or, if such court does not have subject matter jurisdiction thereof, the federal district court of the State of Delaware (the “Delaware Exclusive Forum Provision”). In addition, our certificate of incorporation provides that, unless Sandisk consents in writing to the selection of an alternative forum, the federal district courts of the United States will be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act (the “Federal Forum Provision”). Our certificate of incorporation also provides that, to the fullest extent permitted by law, any person or entity purchasing or otherwise acquiring or holding any interest in shares of our capital stock is deemed to have notice of and consented to the Delaware Exclusive Forum Provision and the Federal Forum Provision.

The Delaware Exclusive Forum Provision is intended to apply to claims arising under Delaware state law and would not apply to claims brought pursuant to the Exchange Act, or the Securities Act, or any other claim for which the federal courts have exclusive jurisdiction. In addition, the Federal Forum Provision is intended to apply to claims arising under the Securities Act and would not apply to claims brought pursuant to the Exchange

155

##### Table of Contents

Act. The exclusive forum provisions that are provided in our certificate of incorporation do not relieve us of our duties to comply with the federal securities laws and the rules and regulations thereunder and, accordingly, actions by our stockholders to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder must be brought in federal courts. Our stockholders are not deemed to have waived Sandisk’s compliance with these laws, rules and regulations.

Limitations on Director and Officer Liability

Under the DGCL, we may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation), by reason of the fact that they are or were our director, officer, employee or agent, or are or were serving at our request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred in connection with such action, suit or proceeding if they acted in good faith and in a manner they reasonably believed to be in or not opposed to our best interests, and, with respect to any criminal action or proceeding, had no reasonable cause to believe their conduct was unlawful. In addition, Section 102(b)(7) of the DGCL provides that a certificate of incorporation may contain a provision eliminating or limiting the personal liability of a director or officer to the corporation or its shareholders for monetary damages for breach of fiduciary duty as a director or officer; provided that such provision shall not eliminate or limit the liability of a director or officer (i) for any breach of the director’s or officer’s duty of loyalty to the corporation or its shareholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL (relating to liability for unauthorized acquisitions or redemptions of, or dividends on, capital stock), (iv) for any transaction from which the director or officer derived an improper personal benefit, or (v) in any action by or in the right of the corporation (with respect to any officer only). Our certificate of incorporation contains the provisions permitted by Section 102(b)(7) of the DGCL.

PLAN OF DISTRIBUTION

The selling stockholder may offer, from time to time, shares of our common stock. We are registering such shares under the terms of a stockholder’s and registration rights agreement between us and the selling stockholder. We will not receive any of the proceeds from the sale of shares of our common stock by the selling stockholder.

The selling stockholder may sell all or a portion of the shares of our common stock directly to purchasers or through underwriters, broker-dealers or agents, who may receive compensation in the form of discounts, concessions or commissions from the selling stockholders or the purchasers of the shares. These discounts, concessions or commissions as to any particular underwriter, broker-dealer or agent may be in excess of those customary in the types of transactions involved.

The shares of our common stock may be sold in one or more transactions on any national securities exchange or quotation service on which the shares may be listed or quoted at the time of sale, in the over-the-counter market or in transactions otherwise than on these exchanges or systems or in the over-the-counter market and in one or more transactions at fixed prices, at prevailing market prices at the time of sale, at varying prices determined at the time of sale or at negotiated prices. These sales may be effected in transactions, which may involve crosses or block transactions. Additionally, the selling stockholder may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. The selling stockholder may use any one or more of the following methods when selling shares:

| • |  | on any national securities exchange or quotation service on which the shares may be listed or quoted at the time of sale, including, the Nasdaq in the case of the common stock;

| • |  | in the over-the-counter market;

| • |  | in transactions otherwise than on these exchanges or services or in the over-the-counter market;

| • |  | through the writing or settlement of options or other hedging transactions, whether the options are listed on an options exchange or otherwise;

| • |  | ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

| • |  | block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;

| • |  | purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

| • |  | an exchange distribution in accordance with the rules of the applicable exchange;

| • |  | a debt-for-equity exchange;

| • |  | privately negotiated transactions;

| • |  | settlement of short sales entered into after the effective date of the registration statement of which this prospectus forms a part;

| • |  | broker-dealers may agree with the selling stockholder to sell a specified number of such shares at a stipulated price per share;

| • |  | a combination of any such methods of sale; and

| • |  | any other method permitted pursuant to applicable law.

In addition, any securities that qualify for sale pursuant to Rule 144 or Regulation S under the Securities Act or under Section 4(1) under the Securities Act may be sold under such rules rather than pursuant to this prospectus or a prospectus supplement, subject to any restriction on transfer contained in the stockholder and registration rights agreement.

157

##### Table of Contents

The selling stockholder may enter into hedging transactions with broker-dealers, which may in turn engage in short sales of the shares of our common stock in the course of hedging the positions they assume. The selling stockholder may also short sell the shares and deliver common stock to close out short positions, or loan or pledge the shares to broker-dealers that in turn may sell these shares. The selling stockholder may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities that require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus and the applicable prospectus supplement, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus and the applicable prospectus supplement. The selling stockholder also may transfer and donate the shares in other circumstances in which case the transferees, donees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus and the applicable prospectus supplement.

The aggregate proceeds to the selling stockholder from the sale of the shares of our common stock will be the purchase price of the shares less discounts and commissions, if any.

For avoidance of doubt, notwithstanding the foregoing, WDC can only dispose of the shares of our common stock registered herein through (1) one or more exchanges of our common stock for WDC debt; and/or (2) distribution to holders of WDC common stock as dividends or in exchange for outstanding shares of WDC common stock.

WDC intends to dispose of the 28,827,787 shares of our common stock registered hereby through one or more exchanges of our common stock for WDC debt, unless it selects another method of distribution. WDC expects that any such debt-for-equity exchange would be effected to satisfy outstanding indebtedness under that certain Amended and Restated Loan Agreement, dated as of January 7, 2022, among WDC, JPMorgan Chase Bank, N.A., as administrative agent, and the lenders party thereto (as amended, the “Credit Agreement”), which governs WDC’s $2.51 billion Term Loan A-3 and revolving credit facility maturing in January 2027. In any such debt-for-equity exchange, it is expected that it will enter into an exchange agreement with the debt exchange parties. Under the exchange agreement, subject to certain conditions, the debt exchange parties, as a principals for their own account, will exchange debt obligations of the selling stockholder held by the debt exchange parties for the shares of our common stock held by WDC. The terms and conditions with respect to any such debt-for-equity exchange will (i) be negotiated at arm’s length, (ii) allocate to the debt exchange parties any risk of loss with respect to the exchange of WDC debt and transfer of the common stock, and (iii) provide that any profit gained shall be solely for the debt exchange parties’ account and no such profit shall inure to the benefit of WDC, Sandisk or their respective affiliates. The amount of indebtedness of WDC held by the debt exchange parties is expected to be sufficient to acquire all of the shares of our common stock to be sold in any offering made in connection with a debt-for-equity exchange. Under federal securities laws, the debt exchange parties will be deemed to be underwriters with respect to any shares of common stock that they acquire in connection with a debt-for-equity exchange and sell in an offering in connection therewith. In the event that the debt exchange parties offer shares of our common stock for sale in connection with a debt-for-equity exchange, WDC will be deemed to be a selling stockholder in such offering solely for federal securities laws purposes.

In offering the shares of our common stock covered by this prospectus and the applicable prospectus supplement, the selling stockholder and any broker-dealers who execute sales for the selling stockholder may be deemed to be “underwriters” within the meaning of Section 2(a)(11) of the Securities Act in connection with such sales. Any profits realized by the selling stockholder and the compensation of any broker-dealer may be deemed to be underwriting discounts and commissions. Selling stockholders who are “underwriters” within the meaning of Section 2(a)(11) of the Securities Act will be subject to the prospectus delivery requirements of the Securities Act and may be subject to certain statutory and regulatory liabilities, including liabilities imposed pursuant to Sections 11, 12 and 17 of the Securities Act and Rule 10b-5 under the Exchange Act.

In order to comply with the securities laws of certain states, if applicable, the shares of our common stock must be sold in such jurisdictions only through registered or licensed brokers or dealers. In addition, in certain states

158

##### Table of Contents

the shares may not be sold unless the shares are registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

The anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of the shares of our common stock pursuant to this prospectus and the applicable prospectus supplement and to the activities of the selling stockholder. In addition, we will make copies of this prospectus and the applicable prospectus supplement available to the selling stockholder for the purpose of satisfying the prospectus delivery requirements of the Securities Act. To the extent applicable, Regulation M may also restrict the ability of any person engaged in the distribution of the common stock to engage in market-making activities with respect to the common stock. All of the foregoing may affect the marketability of the common stock and the ability of any person or entity to engage in market-making activities with respect to the common stock.

There can be no assurance that the selling stockholder will sell any or all of the common stock registered pursuant to the registration statement of which this prospectus forms a part.

If required, we will file a post-effective amendment to the registration statement of which this prospectus is a part to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement. At the time a particular offering of the shares is made, a prospectus supplement, if required, will be distributed, which will set forth the name of the selling stockholder, the aggregate amount of shares being offered and the terms of the offering, including, to the extent required, (1) the name or names of any underwriters, broker-dealers or agents, (2) any discounts, commissions and other terms constituting compensation from the selling stockholder and (3) any discounts, commissions or concessions allowed or reallowed to be paid to broker-dealers.

We have agreed to indemnify the selling stockholder against certain liabilities, including certain liabilities under the Securities Act. We have also agreed, among other things, to bear substantially all expenses (other than underwriting discounts and selling commissions) in connection with the registration and sale of the shares of our common stock covered by this prospectus and the applicable prospectus supplement. Agents and underwriters may be entitled to indemnification by us and the selling stockholder against certain liabilities, including liabilities under the Securities Act, or to contributions with respect to payments which the agents or underwriters may be required to make in respect thereof.

Agents and underwriters and their respective affiliates may engage in transactions with, or perform services for us in the ordinary course of business for which they may receive customary fees and reimbursement of expenses.

The estimated offering expenses payable by us, in addition to any underwriting discounts and commissions that will be paid by the selling stockholder, will be described in the applicable prospectus supplement.

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors

Western Digital Corporation:

Opinion on the Combined Financial Statements

We have audited the accompanying combined balance sheets of the Flash Business of Western Digital Corporation (the Business) as of June 28, 2024 and June 30, 2023, the related combined statements of operations, comprehensive income (loss), cash flows, and changes in parent company net investment for each of the years in the three-year period ended June 28, 2024, and the related notes (collectively, the combined financial statements). In our opinion, the combined financial statements present fairly, in all material respects, the financial position of the Business as of June 28, 2024 and June 30, 2023, and the results of its operations and its cash flows for each of the years in the three-year period ended June 28, 2024, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These combined financial statements are the responsibility of the Business’s management. Our responsibility is to express an opinion on these combined financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Business in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB and in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the combined financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the combined financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the combined financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the combined financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

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

Assessment of variable consideration for sales to resellers

As discussed in Note 1 to the combined financial statements, the Business provides resellers with price protection for inventories held by resellers at the time of published list price reductions and other sales incentive programs. The Business records estimated variable consideration related to these items as a reduction to revenue at the time of revenue recognition. The Business uses judgment in its assessment of variable consideration in contracts to be included in the transaction price. For sales to resellers, the Business’s methodology for estimating variable consideration is based on several factors, including historical pricing information, current pricing trends and channel inventory levels.

F-2

##### Table of Contents

We identified the assessment of variable consideration for sales to resellers as a critical audit matter. A high degree of subjective auditor judgment was required to evaluate the Business’s assumptions for historical pricing information and the level of channel inventory used to estimate variable consideration for sales to resellers as minor changes in these assumptions could cause significant changes in the estimate.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to the Business’s process for estimating the variable consideration, including certain controls related to historical pricing information and the level of channel inventory assumptions. We evaluated the assumptions for historical pricing information by inspecting a sample of customer contracts with resellers and comparing the sales incentives earned during the year to the sales incentive program terms and conditions and recalculating amounts paid to the resellers. We tested the channel inventory levels by comparing the on-hand inventory amounts for a sample of resellers to information obtained from the resellers and evaluated the reasonableness of reconciling items.

We have served as the Business’s auditor since 2023.

NOTES TO COMBINED FINANCIAL STATEMENTS

Note 1. Organization and Basis of Presentation

Description of the Business

The accompanying Combined Financial Statements present, on a historical cost basis, the combined assets, liabilities, revenues and expenses of the flash business of Western Digital Corporation (the “Business”), a business of Western Digital Corporation and its subsidiaries (collectively “WDC” or “Parent”). The Business is a leading developer, manufacturer and provider of data storage devices and solutions based on NAND flash technology. With a differentiated innovation engine driving advancements in storage and semiconductor technologies, our broad and ever-expanding portfolio delivers powerful flash storage solutions for everyone from students, gamers and home offices to the largest enterprises and public clouds to capture, preserve, access and transform an ever-increasing diversity of data. The Business operates primarily in the U.S. and internationally with a significant concentration in Asia Pacific. On October 30, 2023, our Parent announced that its board of directors (the “WDC Board of Directors”) authorized management to pursue a plan to separate the Business into an independent public company. The completion of the separation is subject to certain conditions, including final approval by the WDC Board of Directors. Our Parent is targeting to complete the separation of the Business in the second half of calendar year 2024.

The Business’s solutions include a broad range of solid-state drives, embedded products, removable cards, universal serial bus drives and wafers and components. The Business’s broad portfolio of technology and products address multiple end markets of “Cloud,” “Client” and “Consumer.” The Business also generates license and royalty revenue from its extensive intellectual property (“IP”) portfolio, which is included in each of these three end market categories.

For the avoidance of doubt, when using the terms “we,” “us,” or “our” throughout this report, it is in reference to the Business.

Basis of Presentation

Throughout the periods covered by the Combined Financial Statements, the Business was an operating segment of WDC. Consequently, stand-alone financial statements have not historically been prepared for the Business. The accompanying Combined Financial Statements have been prepared from WDC’s historical consolidated financial statements and accounting records and are presented on a stand-alone basis as if the Business’s operations had been conducted independently from WDC. The Combined Financial Statements include the historical results of operations, financial position and cash flows of the Business in accordance with accounting principles generally accepted in the United States (“GAAP”) and the Business has adopted accounting policies and practices which are generally accepted in the industry in which it operates. As no single legal entity of the Business has a controlling financial interest in all other legal entities, Combined Financial Statements have been prepared.

Intercompany transactions have been eliminated. With the exception of balances associated with lending arrangements reflected within Notes due to (from) Parent in the Combined Balance Sheets, transactions between the Business and the Parent are generally considered to be effectively settled in the Combined Financial Statements at the time the transactions are recorded. The total net effect of the settlement of these transactions is reflected in the Combined Statements of Cash Flows as a financing activity and in the Combined Balance Sheets as Parent company net investment. General financing activities include the net impact of any cash movements resulting from the Parent’s centralized treasury cash management.

The Combined Statements of Operations and Comprehensive Income (Loss) include all revenues and costs directly attributable to the Business as well as an allocation of expenses related to facilities, functions and

services provided by our Parent. Allocation of general corporate expenses from our Parent include, but are not limited to, executive management, finance, tax, legal, information technology, employee benefits administration, treasury, risk management, procurement and other shared services. These corporate expenses have been allocated to the Business based on direct usage or benefit, where identifiable, with the remainder allocated based on headcount, revenue or other relevant measures. The allocated costs are deemed to be settled between the Business and the Parent in the period in which the expense was recorded in the Combined Statements of Operations. The Combined Statements of Cash Flows present these corporate expenses as cash flows from operating activities, as these costs were incurred by our Parent on our behalf. We consider these allocations to be a reasonable reflection of the utilization of services by, or the benefits provided to, the Business. The allocations may not, however, reflect the expense the Business would have incurred as a standalone company for the periods presented. Additionally, these costs may not be indicative of the expenses that the Business will incur in the future or would have incurred if the Business had obtained these services from an unrelated third party. It is not practicable to estimate the actual costs that would have been incurred had the Business been a standalone company during the periods presented. The actual costs that may have been incurred would depend on a number of factors, including the chosen organizational structure, whether functions were outsourced or performed by employees and decisions with respect to areas such as facilities, information technology and operating infrastructure.

Our Parent maintains various stock-based compensation plans at a corporate level. Employees of the Business participate in those programs and a portion of the compensation cost associated with those plans is included in the Business’s Combined Statements of Operations. Stock-based compensation expense has been included within Parent company net investment. The amounts presented in the Combined Financial Statements are not necessarily indicative of future awards and may not reflect the results that the Business would have experienced as a stand-alone entity.

Current and deferred income taxes and related tax expense have been determined based on the stand-alone results of the Business by applying Accounting Standards Codification No. 740, Income Taxes (“ASC 740”), to the Business’s operations in each country as if it were a separate taxpayer (i.e., following the Separate Return Methodology).

The Combined Balance Sheets include all assets and liabilities that are specifically identifiable or otherwise attributable to the Business. Assets and liabilities shared between the Business and the Parent were included in the stand-alone financial statements to the extent the asset is primarily used by the Business. If the Business is not the primary user of the asset, it was excluded entirely from the Combined Financial Statements. The Parent has historically used a centralized approach to cash management and financing of its operations, as needed. Certain of our cash is transferred to the Parent according to centrally managed cash programs by treasury and the Parent funds our operating and investing activities as needed. Cash transfers to and from the Parent’s cash management accounts are reflected as a component of Parent company net investment in the Combined Balance Sheets. Cash and cash equivalents in our Combined Balance Sheets primarily represent cash held locally by entities included in our Combined Financial Statements.

None of the debt obligations of the Parent or corresponding interest expense have been included in the accompanying Combined Financial Statements, as the Business is neither the legal obligor, nor transferee for any portion of such debt. Our Parent’s debt obligations are secured by a lien on substantially all assets and properties of WDC and certain key subsidiaries, which includes assets and properties of the Business.

Fiscal Year

The Business’s fiscal year ends on the Friday nearest to June 30 and typically consists of 52 weeks. Approximately every five to six years, we report a 53-week fiscal year to align the fiscal year with the foregoing policy. Fiscal years 2024, 2023 and 2022 which ended on June 28, 2024, June 30, 2023, and July 1, 2022, respectively, are comprised of 52 weeks, with all quarters presented consisting of 13 weeks. Unless otherwise indicated, references herein to specific years and quarters are to fiscal years and fiscal quarters, and references to financial information are on a combined basis.

Segment Reporting

Operating segments are components of an enterprise for which separate financial information is available and is evaluated regularly by the company’s chief operating decision maker (“CODM”) in deciding how to allocate resources and in assessing performance. The Business currently operates as both a single operating and reportable segment.

Business Separation Costs

On October 30, 2023, our Parent announced that its Board of Directors had completed its strategic review and, after evaluating a comprehensive range of alternatives, authorized WDC to pursue a plan to separate its Hard Disk Drive (“HDD”) and Flash business units to create two independent, public companies. As a result of the plan, the Business has incurred separation and transition costs and expects to incur such costs through the completion of the separation from WDC. The separation and transition costs are recorded within Business separation costs in the Combined Statements of Operations.

Use of Estimates

Management has made estimates and assumptions relating to the reporting of certain assets and liabilities in conformity with U.S. GAAP. These estimates and assumptions have been applied using methodologies that are consistent throughout the periods presented with consideration given to the potential impacts of current macroeconomic conditions. However, actual results could differ materially from these estimates.

Cash Equivalents

The Business’s cash equivalents represent highly liquid investments in money market funds, which are invested in U.S. Treasury securities and U.S. Government agency securities as well as bank certificates of deposit with original maturities at purchase of three months or less. These deposits are typically in excess of U.S. insured limits. Cash equivalents are carried at cost plus accrued interest, which approximates fair value.

Equity Investments

The Business enters into certain strategic investments for the promotion of business and strategic objectives. The equity method of accounting is used if the Business’s ownership interest is greater than or equal to 20.0% but less than a majority or where the Business has the ability to exercise significant influence over operating and financial policies. The Business’s equity in the earnings or losses in equity-method investments is recognized in Other income (expense), net, in the Combined Statements of Operations. Equity earnings or losses in the Business’s investments in Flash Ventures (as defined in Note 9) are reported on a three-month lag.

F-11

##### Table of Contents

The Flash Business of Western Digital Corporation

NOTES TO COMBINED FINANCIAL STATEMENTS – (Continued)

If the Business’s ownership interest is less than 20.0% and the Business does not have the ability to exercise significant influence over operating and financial policies of the investee, the Business accounts for these investments at fair value, or if these equity securities do not have a readily determinable fair value, these securities are measured and recorded using the measurement alternative under Accounting Standards Update (“ASU”) No. 2016-01, “Financial Instruments — Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities,” which is cost minus impairment, if any, plus or minus changes resulting from observable price changes. These investments are recorded within Other non-current assets in the Combined Balance Sheets and are periodically analyzed to determine whether or not impairment indicators exist.

Variable Interest Entities

The Business evaluates its investments and other significant relationships to determine whether any investee is a variable interest entity (“VIE”). If the Business concludes that an investee is a VIE, the Business evaluates its power to direct the activities of the investee, its obligation to absorb the expected losses of the investee and its right to receive the expected residual returns of the investee to determine whether the Business is the primary beneficiary of the investee. If the Business is the primary beneficiary of a VIE, the Business consolidates such entity and reflects the non-controlling interest of other beneficiaries of that entity. The Business does not have any investments in variable interest entities requiring consolidation.

Fair Value of Financial Instruments

The carrying amounts of cash equivalents, accounts receivable, accounts payable and accrued expenses approximate fair value for all periods presented because of the short-term maturity of these assets and liabilities. The carrying value of notes receivable from Flash Ventures (as defined in Note 9) also approximates fair value for all periods presented because they bear variable market rates of interest. The fair value of investments that are not accounted for under the equity method is based on appropriate market information. The carrying amounts of Notes due to Parent and Notes due from Parent approximate their fair value as the notes are due on demand.

Inventories

The Business values inventories at the lower of cost (first-in, first-out) or net realizable value. Inventory write-downs are recorded for the valuation of inventory at the lower of cost or net realizable value by analyzing market conditions and estimates of future sales prices as compared to inventory costs and inventory balances.

The Business evaluates inventory balances for excess quantities and obsolescence on a regular basis by analyzing estimated demand, inventory on hand, sales levels and other information and reduces inventory balances to net realizable value for excess and obsolete inventory based on this analysis. Unanticipated changes in technology or customer demand could result in a decrease in demand for one or more of the Business’s products, which may require a write-down of inventory that could materially affect operating results.

Property, Plant and Equipment

Property and equipment are carried at cost less accumulated depreciation. The cost of property, plant and equipment is depreciated over the estimated useful lives of the respective assets. The Business’s buildings and improvements are depreciated over periods ranging from fifteen to thirty years. The majority of the Business’s machinery and equipment, software and furniture and fixtures, are depreciated on a straight-line basis over a period of two to seven years. Leasehold improvements are amortized over the lesser of the estimated useful lives of the assets or the related lease terms.

NOTES TO COMBINED FINANCIAL STATEMENTS – (Continued)

Goodwill and Other Long-Lived Assets

Goodwill attributed to the Business represents the amount by which the purchase price of businesses acquired in a business combination exceeded the estimated fair value of acquired net assets.

Goodwill is not amortized. Instead, it is tested for impairment on an annual basis or more frequently whenever events or changes in circumstances indicate that goodwill may be impaired. The Business performs an annual impairment test as of the beginning of its fourth quarter or sooner if an indicator of impairment exists. The Business uses qualitative factors to determine whether goodwill is more likely than not impaired and whether a quantitative test for impairment is considered necessary. If the Business concludes from the qualitative assessment that goodwill is more likely than not impaired, the Business is required to perform a quantitative approach to determine the amount of impairment.

The Business is required to use judgment when applying the goodwill impairment test including the identification of reporting units, assignment of assets, liabilities and goodwill to reporting units, and determination of the fair value of each reporting unit. In addition, the estimates used to determine the fair value of reporting units may change based on results of operations, macroeconomic conditions or other factors. Changes in these estimates could materially affect the Business’s assessment of the fair value and goodwill impairment.

The Business’s assessment resulted in no impairment of goodwill in fiscal years 2024 and 2022. In fiscal year 2023, certain macroeconomic conditions caused the Business to perform a quantitative impairment analysis which resulted in a $671 million impairment of goodwill for the fiscal year ended June 30, 2023. See Note 5, Supplemental Financial Statement Data, for additional disclosures related to the goodwill impairment assessment that was performed.

Other long-lived assets are depreciated or amortized over their estimated useful lives based on the pattern in which the economic benefits are expected to be received. Long-lived assets are tested for recoverability whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. If impairment is indicated, the impairment is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets. The estimates of fair value require evaluation of future market conditions and product lifecycles as well as projected revenue, earnings and cash flow. See Note 5, Supplemental Financial Statement Data, for additional disclosures related to the Business’s other intangible assets.

Revenue and Accounts Receivable

The Business recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to the customer. The transaction price to be recognized as revenue is adjusted for variable consideration, such as sales incentives, and excludes amounts collected on behalf of third parties, including taxes imposed by governmental authorities. The Business’s performance obligations are typically not constrained based on the Business’s history with similar transactions and the fact that uncertainties are resolved in a fairly short period of time.

Substantially all of the Business’s revenue is from the sale of tangible products for which the performance obligations are satisfied at a point in time, generally upon delivery. The Business’s services revenue mainly includes professional service arrangements and post contract customer support, warranty as a service and maintenance contracts and was not material for the periods presented. The performance obligations for the Business’s services are generally satisfied ratably over the service period based on the nature of the service provided and contract terms. Similarly, revenue from patent licensing arrangements is recognized based on

F-13

##### Table of Contents

The Flash Business of Western Digital Corporation

NOTES TO COMBINED FINANCIAL STATEMENTS – (Continued)

whether the arrangement provides the customer a right to use or right to access the IP. Revenue for a right to use arrangement is recognized at the time the control of the license is transferred to the customer. Revenue for a right to access arrangement is recognized over the contract period using the time lapse method. For the sales-based royalty arrangements, the Business estimates and recognizes revenue in the period in which customers’ licensable sales occur.

The Business’s customer payment terms are typically less than two months from the date control over the product or service is transferred to the customer. The Business uses the practical expedient and does not recognize a significant financing component for payment considerations of less than one year. The financing components of contracts with payment terms were not material.

The Business provides distributors and retailers, which we refer to collectively as resellers, with limited price protection for inventories held by resellers at the time of published list price reductions. The Business also provides resellers and original equipment manufacturers (“OEMs”) with other sales incentive programs. The Business records estimated variable consideration related to these items as a reduction to revenue at the time of revenue recognition. The Business uses judgment in its assessment of variable consideration in contracts to be included in the transaction price. The Business uses the expected value method to arrive at the amount of variable consideration. The Business constrains variable consideration until the likelihood of a significant revenue reversal is not probable and believes that the expected value method is the appropriate estimate of the amount of variable consideration based on the fact that the Business has a large number of contracts with similar characteristics.

For sales to OEMs, the Business’s methodology for estimating variable consideration is based on the amount of consideration expected to be earned based on the OEMs’ volume of purchases from the Business or other agreed-upon sales incentive programs. For sales to resellers, the Business’s methodology for estimating variable consideration is based on several factors including historical pricing information, current pricing trends and channel inventory levels. Differences between the estimated and actual amounts of variable consideration are recognized as adjustments to revenue.

Marketing development program costs are typically recorded as a reduction of the transaction price and, therefore, of revenue. The Business nets sales rebates against open customer receivable balances if the criteria to offset are met, otherwise they are recorded within other accrued liabilities.

For contracts with multiple performance obligations, the Business evaluates whether each deliverable is a distinct promise and should be accounted for as a separate performance obligation. If a promised good or service is not distinct in accordance with the revenue guidance, the Business combines that good or service with the other promised goods or services in the arrangement until a distinct bundle of goods is identified. If applicable, the Business allocates the transaction price to the performance obligations of each distinct product or service, or distinct bundle, based on their relative standalone selling prices.

The Business records an allowance for doubtful accounts by analyzing specific customer accounts and assessing the risk of loss based on insolvency or other collection issues. In addition, the Business routinely analyzes the various receivable aging categories to establish reserves based on a combination of past due receivables and expected future losses. If the financial condition of a significant customer deteriorates resulting in its inability to pay its accounts when due, or if the Business’s overall loss trajectory changes significantly, an adjustment in the Business’s allowance for doubtful accounts would be required, which could materially affect operating results.

F-14

##### Table of Contents

NOTES TO COMBINED FINANCIAL STATEMENTS – (Continued)

Warranty

The Business records an accrual for estimated warranty costs when revenue is recognized. The Business generally warrants its products for a period of one to five years, with a small number of products having a warranty ranging up to ten years or more. The warranty provision considers estimated product failure rates and trends, estimated replacement costs, estimated repair costs which include scrap costs and estimated costs for customer compensatory claims related to product quality issues, if any. For warranties ten years or greater, including lifetime warranties, the Business uses the estimated useful life of the product to calculate the warranty exposure. A statistical warranty tracking model is used to help prepare estimates and assist the Business in exercising judgment in determining the underlying estimates. The statistical tracking model captures specific details on product reliability, such as factory test data, historical field return rates and costs to repair by product type. Management’s judgment is subject to a greater degree of subjectivity with respect to newly introduced products because of limited field experience with those products upon which to base warranty estimates. Management reviews the warranty accrual quarterly for products shipped in prior periods and which are still under warranty. Any changes in the estimates underlying the accrual may result in adjustments that impact current period gross profit and income. Such changes are generally a result of differences between forecasted and actual return rate experience and costs to repair and could differ significantly from the estimates.

Litigation and Other Contingencies

When the Business becomes aware of a claim or potential claim, the Business assesses the likelihood of any loss or exposure. The Business discloses information regarding each material claim where the likelihood of a loss contingency is probable or reasonably possible. If a loss contingency is probable and the amount of the loss can be reasonably estimated, the Business records an accrual for the loss. In such cases, there may be an exposure to potential loss in excess of the amount accrued. Where a loss is not probable but is reasonably possible or where a loss in excess of the amount accrued is reasonably possible, the Business discloses an estimate of the amount of the loss or range of possible losses for the claim if a reasonable estimate can be made, unless the amount of such reasonably possible losses is not material to the Business’s financial position, results of operations or cash flows. The ability to predict the ultimate outcome of such matters involves judgments, estimates and inherent uncertainties. The actual outcome of such matters could differ materially from management’s estimates. See Note 14, Legal Proceedings, for additional disclosures related to the Business’s litigation.

Advertising Expense

Advertising costs are expensed as incurred and amounted to $31 million, $35 million and $47 million in 2024, 2023 and 2022, respectively. These expenses are included in Selling, general and administrative in the Combined Statements of Operations.

Research and Development Expense

Research and development (“R&D”) expenditures are expensed as incurred.

Income Taxes

Income taxes are calculated as if the Business files tax returns on a stand-alone basis separate from the Parent. The Business accounts for income taxes under the asset and liability method, which provides that deferred tax assets and liabilities be recognized for temporary differences between the financial reporting basis and the tax basis of assets and liabilities and expected benefits of utilizing net operating loss (“NOL”) and tax credit carryforwards. The Business records a valuation allowance when it is more likely than not that the deferred

F-15

##### Table of Contents

The Flash Business of Western Digital Corporation

NOTES TO COMBINED FINANCIAL STATEMENTS – (Continued)

tax assets will not be realized. Each quarter, the Business evaluates the need for a valuation allowance for its deferred tax assets and adjusts the valuation allowance so that the Business records net deferred tax assets only to the extent that it has concluded it is more likely than not that these deferred tax assets will be realized. The Business accounts for interest and penalties related to income taxes as a component of the provision for income taxes.

The Business recognizes liabilities for uncertain tax positions based on a two-step process. To the extent a tax position does not meet a more-likely-than-not level of certainty, no benefit is recognized in the financial statements. If a position meets the more-likely-than-not level of certainty, it is recognized in the financial statements at the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. Interest and penalties related to unrecognized tax benefits are recognized in liabilities recorded for uncertain tax positions and are recorded in the provision for income taxes. The actual liability for unrealized tax benefits in any such contingency may be materially different from the Business’s estimates, which could result in the need to record additional liabilities for unrecognized tax benefits or potentially adjust previously recorded liabilities for unrealized tax benefits and may materially affect the Business’s operating results.

Stock-based Compensation Expense

The Business’s employees have historically participated in Parent’s stock-based compensation programs. Stock-based compensation expense has been attributed to the Business based on the awards and terms previously granted to the Business’s direct employees, as well as an allocation of Parent’s corporate and shared functional employee expenses.

Certain employees of the Business have been granted restricted stock or restricted stock units under which shares of the Parent’s common stock vest based on the passage of time or achievement of performance and market conditions. Under the Parent’s Employee Stock Purchase Plan (“ESPP”), eligible employees may authorize payroll deductions of up to 10% of their eligible compensation. The fair value of ESPP purchase rights issued is estimated at the date of grant of the purchase rights using the Black-Scholes-Merton option-pricing model. The Black-Scholes-Merton option-pricing model requires the input of assumptions such as the expected stock price volatility and the expected period until options are exercised. Purchase rights under the ESPP are generally granted on either June 1st or December 1st of each year.

Other Comprehensive Income (Loss), Net of Tax

Other comprehensive income (loss), net of tax refers to gains and losses that are recorded as an element of equity but are excluded from net income (loss). The Business’s other comprehensive income (loss), net of tax is primarily comprised of unrealized gains or losses on foreign exchange contracts designated as cash flow hedges and foreign currency translation.

Derivative Contracts

The majority of the Business’s transactions are in U.S. dollars; however, some transactions are based in various foreign currencies. The Business purchases foreign exchange contracts to hedge the impact of foreign currency exchange fluctuations on certain underlying assets, liabilities and commitments for Operating expenses and product costs denominated in foreign currencies. The purpose of entering into these hedging transactions is to minimize the impact of foreign currency fluctuations on the Business’s results of operations. Substantially all of these contract maturity dates do not exceed 12 months. All foreign exchange contracts are for risk management purposes only. The Business does not purchase foreign exchange contracts for speculative or

F-16

##### Table of Contents

NOTES TO COMBINED FINANCIAL STATEMENTS – (Continued)

trading purposes. The Business had foreign exchange contracts with commercial banks for European euro, Canadian dollar, Japanese yen, Malaysian ringgit, Korean won and Israeli shekel, which had an aggregate notional amount of $2.9 billion and $4.2 billion at June 28, 2024 and June 30, 2023, respectively.

If the derivative is designated as a cash flow hedge and is determined to be highly effective, the change in fair value of the derivative is initially deferred in Other comprehensive income (loss), net of tax. These amounts are subsequently recognized into earnings when the underlying cash flow being hedged is recognized into earnings. Recognized gains and losses on foreign exchange contracts are reported in cost of revenue and operating expenses and presented within cash flows from operating activities. Hedge effectiveness is measured by comparing the hedging instrument’s cumulative change in fair value from inception to maturity to the underlying exposure’s terminal value. The Business determined the ineffectiveness associated with its cash flow hedges to be immaterial to the Combined Financial Statements for the periods presented.

A change in the fair value of undesignated hedges is recognized in earnings in the period incurred and is reported in other income (expense), net.

Leases

The Business leases certain domestic and international facilities under long-term, non-cancelable operating leases that expire at various dates through 2039. These leases include no material variable or contingent lease payments. Operating lease assets and liabilities are recognized based on the present value of the remaining lease payments discounted using the Business’s incremental borrowing rate. Operating lease assets also include prepaid lease payments minus any lease incentives. Extension or termination options present in the Business’s lease agreements are included in determining the right-of-use asset and lease liability when it is reasonably certain the Business will exercise that option. Lease expense is recognized on a straight-line basis over the lease term.

Note 2. Recent Accounting Pronouncements

Accounting Pronouncements Recently Adopted

In September 2022, the Financial Accounting Standards Board (“FASB”) issued an accounting standards update (“ASU”) No. 2022-04, “Liabilities-Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations”, which requires annual and interim disclosures for entities that use supplier finance programs in connection with the purchase of goods and services. The ASU requires the Business to provide disclosure of outstanding obligations to such suppliers for all balance sheet dates presented beginning with the Business’s first quarter of 2024 and to provide certain rollforward information related to those obligations beginning in the Business’s first fiscal quarter of 2025, with early adoption permitted. The ASU does not affect the recognition, measurement or financial statement presentation of supplier finance program obligations. The Business adopted the guidance on the first day of fiscal year 2024 and the adoption did not have a material impact on its Combined Financial Statements.

Recently Issued Accounting Pronouncements Not Yet Adopted

In November 2023, the FASB issued ASU No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures,” which expands on segment reporting requirements primarily through enhanced disclosures surrounding significant segment expenses. The ASU expands on existing segment reporting requirements to require that a public entity disclose, on an annual and interim basis, significant segment expenses that are regularly provided to an entity’s CODM, a description of other segment items by reportable segment, and

F-17

any additional measures of a segment’s profit or loss used by the CODM when deciding how to allocate resources. These incremental disclosures will be required beginning with the Business’s financial statements for the year ending June 27, 2025. The Business expects to provide any required disclosures at that time.

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The ASU calls for enhanced income tax disclosure requirements surrounding the tabular rate reconciliation and income taxes paid. The amendments are effective for the Business’s fiscal year 2026, with early adoption permitted. The Business is currently compiling the information required for these disclosures. These incremental disclosures will be required beginning with the Business’s financial statements for the year ending June 27, 2025. The Business expects to provide any required disclosures at that time.

Note 3. Geographic Information and Concentrations of Risk

Disaggregated Revenue

The Business’s broad portfolio of technology and products addresses multiple end markets. Cloud represents a large and growing end market comprised primarily of products for public or private cloud environments and enterprise customers. Through the Client end market, the Business provides its OEM and channel customers a broad array of high-performance flash solutions across personal computer, mobile, gaming, automotive, virtual reality headsets, at-home entertainment and industrial spaces. The Consumer end market is highlighted by the Business’s broad range of retail and other end-user products, which capitalize on the strength of the Business’s product brand recognition and vast points of presence around the world.

The Business’s disaggregated revenue information is as follows:

Customer Concentration and Credit Risk

The Business sells its products to computer manufacturers and OEMs, cloud service providers, resellers, distributors and retailers throughout the world. For fiscal year 2024, no customer accounted for more than 10% of the Business’s net revenue. For fiscal year 2023, one customer accounted for 15% of the Business’s net revenue. For fiscal year 2022, one customer accounted for 11% of the Business’s net revenue. For 2024, 2023 and 2022, the Business’s top 10 customers accounted for 41%, 47% and 47% of the Business’s net revenue, respectively.

The Business performs ongoing credit evaluations of its customers’ financial condition and generally requires no collateral. The Business maintains allowances for potential credit losses, and such losses have historically been within management’s expectations. At any given point in time, the total amount outstanding from any one of a number of its customers may be individually significant to the Business’s financial results. As of June 28, 2024, the Business had net accounts receivable of $935 million, and one customer accounted for 10% of the Business’s outstanding accounts receivable. As of June 30, 2023, the Business had net accounts receivable of $539 million, and two customers accounted for 39% and 18% of the Business’s outstanding accounts receivable, respectively. Reserves for potential credit losses were not material as of each period end.

The Business also has cash equivalent and investment policies that limit the amount of credit exposure to any one financial institution or investment instrument and requires that investments be made only with financial institutions or in investment instruments evaluated as highly credit-worthy.

Supplier Concentration

All of the Business’s flash products require silicon wafers for the memory and controller components. The Business’s flash memory wafers are currently supplied almost entirely from Flash Ventures (as defined in Note 9) and the Business’s controller wafers are all manufactured by third-party sources. The failure of any of these sources to deliver silicon wafers could have a material adverse effect on the Business’s business, financial condition and results of operations.

NOTES TO COMBINED FINANCIAL STATEMENTS – (Continued)

In addition, some key components are purchased from single-source vendors for which alternative sources are currently not available. Shortages could occur in these essential materials due to an interruption of supply or increased demand in the industry. If the Business was unable to procure certain of such materials, the Business’s sales could decline, which could have a material adverse effect upon its results of operations. The Business also relies on third-party subcontractors to assemble and test a portion of its products. The Business does not have long-term contracts with some of these subcontractors and cannot directly control product delivery schedules or manufacturing processes. This could lead to product shortages or quality assurance problems that could increase the manufacturing costs of the Business’s products and have material adverse effects on the Business’s operating results.

Note 4. Revenues

Contract assets represent the Business’s rights to consideration where performance obligations are completed but the customer payments are not due until another performance obligation is satisfied. The Business did not have any contract assets as of June 28, 2024, or June 30, 2023. Contract liabilities relate to customers’ payments in advance of performance under the contract and primarily relate to remaining performance obligations under professional service and support and maintenance contracts. Contract liabilities as of June 28, 2024, and June 30, 2023, and changes in contract liabilities during 2024 and 2023 were not material.

The Business incurs sales commissions and other direct incremental costs to obtain sales contracts. The Business has applied the practical expedient to recognize the direct incremental costs of obtaining contracts as an expense when incurred if the amortization period is expected to be one year or less or the amount is not material, with these costs charged to selling, general and administrative expenses. The Business had no direct incremental costs to obtain contracts that have an expected benefit of greater than one year.

The Business applies the practical expedients and does not disclose transaction price allocated to the remaining performance obligations for (i) arrangements that have an original expected duration of one year or less, which mainly consist of the support and maintenance contracts, and (ii) variable consideration amounts for sale-based or usage-based royalties for intellectual property license arrangements, which typically range longer than one year. Remaining performance obligations are mainly attributed to right-to-access patent license arrangements, professional service arrangements and customer support and service contracts which will be recognized over the remaining contract period. The transaction price allocated to the remaining performance obligations as of June 28, 2024, was not material.

The Business determined that its single operating segment was also its single reporting unit. Goodwill is not amortized. Instead, it is tested for impairment annually as of the beginning of the Business’s fourth quarter, or more frequently if events or changes in circumstances indicate that goodwill may be impaired. The Business uses qualitative factors to determine whether goodwill is more-likely-than-not impaired and whether a quantitative test for impairment is considered necessary. If the Business concludes from the qualitative assessment that goodwill is more-likely-than-not-impaired, the Business is required to perform a quantitative approach to determine the amount of impairment.

Management did not identify any impairment indicators as of June 28, 2024 and did not incur any goodwill impairment charges for 2024. During fiscal year 2023, management identified several factors, including changes in industry and macroeconomic conditions, that warranted a quantitative analysis of impairment for the Business. The fair value of the operating segment was based on a weighting of two valuation methodologies: an income approach and a market approach.

The income approach was based on the present value of the projected discounted cash flows (“DCF”) expected to be generated by the operating segment. Those projections required the use of significant estimates and assumptions specific to the reporting unit as well as those based on general economic conditions, which included, among other factors, revenue growth rates, gross margins, operating costs, capital expenditures, assumed tax rates and other assumptions deemed reasonable by management. The present value was based on applying a weighted average cost of capital (“WACC”) which considered long-term interest rates and cost of equity based on the Business’s risk profile.

The market approach was based on a guideline Business method, which analyzed market multiples of revenue for a group of comparable public companies.

The Business reconciled the aggregated estimated fair value of the operating segment to our Parent’s market capitalization, including consideration of a control premium representing the estimated amount a market participant would pay to obtain a controlling interest in the Business.

Management determined that the carrying value of the reporting unit exceeded its fair value as derived from the valuation methodologies described above, resulting in recognition of a $671 million impairment charge for the fiscal year ended June 30, 2023.

The Business is required to use judgment when assessing goodwill for impairment, including evaluating the impact of industry and macroeconomic conditions and the determination of the fair value of the reporting unit. In addition, the estimates used to determine the fair value of the reporting unit as well as the actual carrying value may change based on future changes in the Business’s results of operations, macroeconomic conditions or other factors. Changes in these estimates could materially affect the Business’s assessment of the fair value and goodwill impairment. In addition, if negative macroeconomic conditions continue or worsen, goodwill could become further impaired, which could result in an additional impairment charge and materially adversely affect the Business’s financial condition and results of operations.

In May 2022, the Business decided to exit its RISC-V development operations and completed the sale of a portion of the business for $25 million. The sale of this business included the transfer of a small number of employees and an immaterial amount of other tangible and intangible assets as well as goodwill. The transaction resulted in a gain of approximately $9 million recorded in employee termination, asset impairment and other charges in the Combined Statements of Operations for the fiscal year ended July 1, 2022. The revenues and expenses related to this business were not material to the Combined Financial Statements and did not qualify to

Accounts receivable, net

From time to time, in connection with factoring agreements, our Parent sells certain of our trade accounts receivable without recourse to third-party purchasers in exchange for cash. In 2024, 2023 and 2022 the Parent sold trade accounts receivable of the Business and received cash proceeds of $339 million, $370 million and $103 million, respectively. The discounts on the trade accounts receivable sold during the periods were not material and were recorded within other income (expense), net in the Combined Statements of Operations. No factored receivables were outstanding as of June 28, 2024, and $70 million of factored receivables remained outstanding as of June 30, 2023.

Note 8. Employee Benefit Plans

Defined Benefit Plans

The Business sponsors a defined benefit pension plan that is solely available for employees located in South Korea. As of June 28, 2024, and June 30, 2023, the plan had a net unfunded status of $6 million and $5 million, respectively, reported within other liabilities on the Combined Balance Sheets. Total pension expense included in cost of revenue and operating expenses in the Combined Statements of Operations was not material for each of the fiscal years ended June 28, 2024, June 30, 2023, and July 1, 2022. No employees of the Business participate in defined benefit pension plans sponsored by the Parent or its subsidiaries.

Defined Contribution Plans

Our eligible employees participate in a 401(k)-matching program, Western Digital Corporation 401(k) Plan (the “Plan”), maintained by the Parent. The Plan covers substantially all domestic employees, subject to certain eligibility requirements. Eligible employees receive employer matching contributions immediately upon hire unless the individual is covered by a collective bargaining agreement, provides services as a consultant, intern, independent contractor, leased or temporary employee or otherwise is not treated as a common-law employee.

Through December 31, 2021, eligible employees were generally able to contribute up to 75% of their eligible compensation on a combined pre-tax and Roth basis, 10% on a combined pre-tax catch-up and Roth catch-up basis, and 10% on a non-Roth after-tax basis subject to Internal Revenue Service (“IRS”) limitations. Eligible employees are generally able to contribute up to 85% of their eligible compensation on a combined pre-tax and Roth basis regardless of age, and 10% of their eligible compensation on an after-tax basis, all subject to IRS limitations. The Business may make a basic matching contribution equal to 50% of each eligible participant’s contribution that does not exceed 6% of the eligible participant’s annual compensation in the year of contribution. Furthermore, the Business’s employer matching contributions vest immediately. Contributions, including the Business’s matching contribution to the Plan, are recorded as soon as administratively possible after the Business makes payroll deductions from Plan participants.

Effective February 18, 2023, the Business announced its decision to suspend matching contributions through the end of the calendar year 2023. The Business later resumed matching contributions on January 1, 2024.

For 2024, 2023 and 2022, the Plan contributions attributable to the Business were $5 million, $9 million and $15 million, respectively.

The additional future payments are scheduled as follows, based on Japanese yen to U.S. dollars exchange rate as of June 28, 2024: $372 million in fiscal year 2025, $29 million in fiscal year 2026, $109 million in fiscal year 2027, $87 million in fiscal year 2028, and $13 million in fiscal year 2029. As of June 28, 2024, in addition to the requirements to make building depreciation prepayments, the Business will also make payments for building depreciation of approximately $290 million at varying dates through fiscal year 2035.

The Business accounts for its ownership position of each entity within Flash Ventures under the equity method of accounting. The financial and other support provided by the Business in all periods presented was either contractually required or the result of a joint decision to expand wafer capacity, transition to new technologies or refinance existing equipment lease commitments. Entities within Flash Ventures are VIEs. The Business evaluated whether it is the primary beneficiary of any of the entities within Flash Ventures for all periods presented and determined that it is not the primary beneficiary of any of the entities within Flash Ventures because it does not have a controlling financial interest in any of those entities. In determining whether the Business is the primary beneficiary, the Business analyzed the primary purpose and design of Flash Ventures, the activities that most significantly impact Flash Ventures’ economic performance, and whether the Business had the power to direct those activities. The Business concluded, based upon its 49.9% ownership, the voting structure and the manner in which the day-to-day operations are conducted for each entity within Flash Ventures, that the Business lacked the power to direct most of the activities that most significantly impact the economic performance of each entity within Flash Ventures.

The following table presents the notes receivable from, and equity investments in, Flash Ventures for the periods presented:

|  | June 28, 2024 |  |  | June 30, 2023 |

During 2024, 2023 and 2022 the Business made net payments to Flash Ventures of $3.35 billion, $4.20 billion, $4.70 billion for purchased flash-based memory wafers and net loans.

The Business makes, or will make, loans to Flash Ventures to fund equipment investments for new process technologies and additional wafer capacity. The Business aggregates its Flash Ventures’ notes receivable into one class of financing receivables due to the similar ownership interest and common structure in each Flash Venture entity. For all reporting periods presented, no loans were past due, and no loan impairments were recorded. The Business’s notes receivable from each Flash Ventures entity, denominated in Japanese yen, are secured by equipment owned by that Flash Ventures entity.

As of June 28, 2024, and June 30, 2023, the Business had accounts payable balances due to Flash Ventures of $313 million and $292 million, respectively.

The Business’s maximum reasonably estimable loss exposure (excluding lost profits) as a result of its involvement with Flash Ventures, based upon the Japanese yen to U.S. dollar exchange rate at June 28, 2024, is presented below. Investments in Flash Ventures are denominated in Japanese yen, and the maximum estimable loss exposure excludes any cumulative translation adjustment due to revaluation from the Japanese yen to the U.S. dollar.

As of June 28, 2024, the Business’s Parent company net investment included undistributed earnings of Flash Ventures of $162 million.

The Business is obligated to pay for variable costs incurred in producing its share of Flash Ventures’ flash-based memory wafer supply, based on its three-month forecast, which generally equals 50% of Flash Ventures’ output. In addition, the Business is obligated to pay for half of Flash Ventures’ fixed costs regardless of the output the Business chooses to purchase. The Business is not able to estimate its total wafer purchase commitment obligation beyond its rolling three-month purchase commitment because the price is determined by reference to the future cost of producing the semiconductor wafers. In addition, the Business is committed to fund 49.9% to 50.0% of capital investments that a Flash Ventures entity decided to make to the extent that Flash Ventures entity’s operating cash flow is insufficient to fund these investments.

Flash Ventures has historically operated near 100% of its manufacturing capacity. During 2024 and 2023, as a result of flash business conditions, the Business temporarily reduced its utilization of its share of Flash Ventures’ manufacturing capacity to an abnormally low level to more closely align the Business’s flash-based wafer supply with projected demand. In 2024 and 2023, the Business incurred costs of $249 million and $286 million, respectively, associated with the reduction in utilization related to Flash Ventures, which was recorded as a charge to cost of revenue.

In February 2022, contamination of certain material used in manufacturing processes occurred at both the Yokkaichi and Kitakami, Japan fabrication facilities, resulting in damage to inventory units in production, a temporary disruption to production operations and a reduction in the Business’s flash wafer availability. During 2022, the Business incurred charges of $207 million related to this contamination incident that were recorded in cost of revenue, which primarily consisted of scrapped inventory and rework costs, decontamination and other costs needed to restore the facilities to normal capacity and under absorption of overhead costs. During 2024, the Business received a recovery of $36 million related to this incident from its insurance carriers, which was recorded in cost of revenue. The Business continues to pursue recovery of its remaining losses associated with this event; however, the total amount of recovery cannot be estimated at this time.

Unis Ventures

WDC also has a joint venture with Unisplendour Corporation Limited and Unissoft (Wuxi) Group Co. Ltd. (“Unis”), referred to as the “Unis Venture”, to market and sell the Business’s products in China and to develop data storage systems for the Chinese market in the future. Pursuant to the separation and distribution agreement, it is expected that the Unis Venture will be minority owned by the Business and majority owned by Unis following the separation. The Unis Venture has not historically been managed as a component of the Business and as such the related equity method investment is not reflected within our Combined Financial Statements. For the years ended June 28, 2024, June 30, 2023, and July 1, 2022, the Business recognized approximately 1%, 2% and 1% of its combined revenue on products distributed by the Unis Venture, respectively. The outstanding accounts receivable due from the Unis Venture was 4% and 2% of Accounts receivable, net as of June 28, 2024, and June 30, 2023, respectively.

Agreement to Sell a Majority Interest in our Parent’s Subsidiary

In March 2024, SanDisk China (an indirect wholly owned subsidiary of WDC) entered into an Equity Purchase Agreement to sell 80% of its equity interest in SanDisk Semiconductor (Shanghai) Co. Ltd. (“SDSS”) (an indirect wholly-owned subsidiary of WDC which holds one of the Business’s manufacturing facilities) to JCET Management Co., Ltd. (“JCET”, a wholly-owned subsidiary of JCET Group Co., Ltd. a Chinese publicly listed company), thereby forming a joint venture between SanDisk China and JCET. Closing of the transaction is subject to the satisfaction or waiver of certain conditions, after which, JCET will own 80% of the equity interest in SDSS, with SanDisk China owning the remaining 20%. Following the Closing, our Parent expects to enter into various ancillary agreements, including (i) a shareholders agreement governing the joint venture relationships from and after the Closing; (ii) a supply agreement with the joint venture to supply the Business with certain flash-based products currently produced by SDSS, which may include flash memory cards, embedded flash products and flash components; and (iii) an intellectual property license agreement granting SDSS certain intellectual property rights on a royalty-free basis for use in manufacturing products on the Business’s behalf for the term of and pursuant to the Supply Agreement.

Sale-Leaseback

In August 2023, our Parent entered into an agreement for the sale and leaseback of its facility in Milpitas, California and received gross proceeds of $191 million in cash. A substantial majority of these assets are associated with the Business and all are included in our Combined Balance Sheet as of June 30, 2023. As a result, $134 million of consideration from the sale-leaseback transaction has been allocated to us on a relative square footage basis and reflected as a cash inflow from investing activities within the Combined Statements of Cash Flows for fiscal year 2024. In connection with the sale and leaseback, the Business recorded a gain of $60 million upon closing of the transaction in September 2023. For more information, see Note 13, Employee Termination, Asset Impairment and Other.

The property is being leased back at an annual rate of $16 million for the first year and increasing by 3% per year thereafter through January 1, 2039. The lease includes three 5-year renewal options and one 4-year renewal option for the ability to extend through December 2057. The full amount of the associated operating lease liability and right of use asset for this facility has been included in the Combined Balance Sheet as of June 28, 2024. This facility is utilized in the Business’s operations and a portion of the total annual lease expense will be allocated to the Business in future periods based on the continued usage of the facility.

Purchase Agreements and Other Commitments

In the normal course of business, the Business enters into purchase orders with suppliers for the purchase of components used to manufacture its products. These purchase orders generally cover forecasted component supplies needed for production during the next quarter, are recorded as a liability upon receipt of the components, and generally may be changed or canceled at any time prior to shipment of the components. The Business also enters into long-term agreements with suppliers that contain fixed future commitments, which are contingent on

Note 11. Stock-based Compensation Expense

Certain of our employees participate in our Parent’s equity-based incentive plans. Under the Western Digital Corporation 2021 Equity Incentive Plan (the “2021 Plan”) and the Western Digital Corporation Amended and Restated 2017 Performance Incentive Plan (the “2017 Plan”), our employees were awarded stock-based incentive awards in a number of forms, including nonqualified stock options. Upon the effective date of the 2021 Plan, no new awards were granted under the 2017 Plan. The types of awards that may be granted under the 2021 Plan include stock options, stock appreciation rights (“SARs”), RSUs, PSUs, restricted stock and other forms of awards granted or denominated in the Parent’s common stock or units of the Parent’s common stock, as well as cash awards. Awards granted to our employees under the incentive plans generally vest over periods ranging from two to four years. We measure stock-based compensation for all stock-based incentive awards at fair value on the grant date. Stock-based compensation expense is generally recognized on a straight-line basis over the requisite service periods of the awards. Compensation costs associated with our employees’ participation in the incentive plans have been specifically identified for employees who exclusively support our operations and are allocated to us as part of the cost allocations from our Parent. We include the related expense in operating expense (research and development and selling, general and administrative) and cost of revenue on our Combined Statements of Operations, depending on the nature of the employee’s role in our operations.

The table below summarizes total costs charged to the Business related to the Business’s employees’ participation in our Parent’s incentive plan during the years ended June 28, 2024, June 30, 2023, and July 1, 2022:

The Tax Cuts and Jobs Act (the “2017 Act”), enacted on December 22, 2017, includes a broad range of tax reform proposals affecting businesses. Our Parent completed its accounting for the tax effects of the enactment of the 2017 Act during the second quarter of 2019. However, the U.S. Treasury and the IRS have issued tax guidance on certain provisions of the 2017 Act since the enactment date, and the Business anticipates the issuance of additional regulatory and interpretive guidance. The Parent applied a reasonable interpretation of the 2017 Act along with the then-available guidance in finalizing its accounting for the tax effects of the 2017 Act. Any additional regulatory or interpretive guidance would constitute new information, which may require further refinements to the Business’s estimates in future periods.

On August 16, 2022, President Biden signed into law the Inflation Reduction Act of 2022, which contained significant law changes related to tax, climate, energy and health care. The tax measures include, among other things, a corporate alternative minimum tax (“CAMT”) of 15% on corporations with three-year average annual adjusted financial statement income (“AFSI”) exceeding $1.00 billion. The Business is not subject to the CAMT of 15% for fiscal year 2024 as its average annual AFSI did not exceed $1.00 billion for the preceding three-year period.

Deferred tax assets, net |  | $ | 81 |  |  | $ | 48 |

Deferred tax assets and deferred tax liabilities are shown on the Combined Balance Sheets netted on a jurisdictional basis.

The assessment of valuation allowances against deferred tax assets requires estimations and significant judgment. The Business continues to assess and adjust its valuation allowance based on operating results and market conditions. After weighing both the positive and negative evidence available, including, but not limited to, earnings history, projected future outcomes, industry and market trends, and the nature of each of the deferred tax assets, the Business determined that it is able to realize most of its deferred tax assets with the exception of certain loss and credit carryforwards.

The Business is permanently reinvested with respect to certain foreign earnings. There is no unrecognized deferred tax liability associated with the repatriation of these foreign undistributed earnings as it can be achieved without additional federal tax consequences.

Tax Holidays and Carryforwards

A substantial portion of the Business’s manufacturing operations in Malaysia operate under various tax holidays and tax incentive programs, which will expire in whole or in part at various dates during 2028 through 2031. Certain of the holidays may be extended if specific conditions are met.

As of June 28, 2024, the Business does not have federal and state NOL/tax credit carryforwards. As of June 28, 2024, the Business had varying amounts of foreign NOL carryforwards that do not expire or, if not used, expire in various years, depending on the country. The major jurisdictions within which the Business receives foreign NOL carryforwards and the related amounts and expiration dates of these NOL carryforwards are as follows:

Jurisdiction |  | NOL Carryforward Amount |  |  | Expiration |
|  | (in millions) |
Malaysia |  | $ | 44 |  |  |  | 2028 |
Netherlands |  |  | 12 |  |  |  | 2026 |

Uncertain Tax Positions

With the exception of certain unrecognized tax benefits that are directly associated with the tax position taken, unrecognized tax benefits are presented gross in the Combined Balance Sheets.

The following is a tabular reconciliation of the total amounts of unrecognized tax benefits excluding accrued interest and penalties:

|  | 2024 |  |  | 2023 |  |  | 2022 |
|  | (in millions) |
Unrecognized tax benefit, beginning balance |  | $ | 25 |  |  | $ | 17 |  |  | $ | 11 |
Gross increases related to current year tax positions |  |  | 15 |  |  |  | 10 |  |  |  | 7 |

Settlements |  |  | — |  |  |  | — |  |  |  | — |
Unrecognized tax benefit, ending balance |  | $ | 47 |  |  | $ | 25 |  |  | $ | 17 |

As of June 28, 2024, June 30, 2023, and July 1, 2022, the portion of the gross unrecognized tax benefits, if recognized, that would affect the effective tax rate is $47 million, $25 million and $17 million, respectively. Interest and penalties related to unrecognized tax benefits are recognized in liabilities recorded for uncertain tax positions and are recorded in the provision for income taxes. Accrued interest and penalties included in the Business’s liability related to unrecognized tax benefits as of June 28, 2024, June 30, 2023, and July 1, 2022 was $9 million, $5 million and $5 million, respectively. As of June 28, 2024, June 30, 2023, and July 1, 2022 the Business’s payables related to unrecognized tax benefits, including accrued interest and penalties, were $56 million, $30 million and $22 million, respectively. The remaining payables related to unrecognized tax benefits are included in other liabilities on the Combined Balance Sheets.

The Business’s Parent files U.S. Federal, U.S. state and foreign tax returns. For both federal and state tax returns, with few exceptions, our Parent is subject to examination from 2013 through 2022. Our Parent is no longer subject to examination by the IRS for periods prior to 2012, although carry forwards generated prior to those periods may still be adjusted upon examination by the IRS or state taxing authority if they either have been or will be used in a subsequent period. In the major foreign jurisdictions where there is no tax holiday, our Parent could be subject to examination as noted below:

Jurisdiction |  | Period Subject to Examination |
China (calendar) |  |  | 2014-2023 |
Ireland (fiscal) |  |  | 2020-2023 |
India (fiscal) |  |  | 2009-2023 |
Israel (fiscal) |  |  | 2014-2023 |
Japan (fiscal) |  |  | 2017-2023 |
Malaysia (fiscal) |  |  | 2017-2023 |
Singapore (fiscal) |  |  | 2020-2023 |
United Kingdom (fiscal) |  |  | 2022-2023 |

The Business believes that adequate provision has been made for any adjustments that may result from any other tax examinations. However, the outcome of such tax examinations cannot be predicted with certainty. If any issues addressed in the Business’s tax examinations are resolved in a manner not consistent with management’s expectations, the Business could be required to adjust its provision for income taxes in the period such resolution occurs. As of June 28, 2024, and June 30, 2023, with the exception of the tentative settlement, it was not possible to estimate the amount of change, if any, in the unrecognized tax benefits that is reasonably possible within the next twelve months. Any significant change in the amount of the Business’s liability for unrecognized tax benefits would most likely result from additional information relating to the examination of the Business’s tax returns.

Note 13. Employee Termination, Asset Impairment and Other

Business Realignment

The Business periodically incurs charges to realign its operations with anticipated market demand, primarily consisting of organization rationalization designed to streamline its business, reduce its cost structure and focus its resources. The Business may also record credits related to gains upon the sale of property in connection with these activities. The Business recognized a loss of $5 million related to asset impairment and other charges and a gain of $60 million related to the sale and leaseback of the Milpitas facility for the fiscal year ended June 28, 2024, a loss of $1 million on the disposal of assets associated with these activities for the fiscal year ended June 30, 2023, and a gain of $9 million related to business divestitures partially offset by a $3 million loss on the disposal of assets associated with these activities for the fiscal year ended July 1, 2022.

The Business recorded the following charges related to these actions:

|  | 2024 |  |  | 2023 |  |  | 2022 |

Note 14. Legal Proceedings

In the normal course of business, the Business is subject to legal proceedings, lawsuits and other claims. Although the ultimate aggregate amount of probable monetary liability or financial impact with respect to these other matters is subject to many uncertainties, management believes that any monetary liability or financial impact to the Business from these matters, individually and in the aggregate, would not be material to the Business’s financial condition, results of operations or cash flows. However, any monetary liability and financial impact to the Business from these matters could differ materially from the Business’s expectations.

Note 15. Summarized Financial Information

Pursuant to Rule 4-08(g) of Regulation S-X under the Securities Act, the Business presents summarized financial information for the combined accounts of its non-consolidated joint ventures, which are accounted for using the equity method.

NOTES TO CONDENSED COMBINED FINANCIAL STATEMENTS

Note 1. Organization and Basis of Presentation

Description of the Company

Sandisk Corporation (“Company,” “we,” “us,” or “our”) is a leading developer, manufacturer and provider of data storage devices and solutions based on NAND flash technology. With a differentiated innovation engine driving advancements in storage and semiconductor technologies, our broad and ever-expanding portfolio delivers powerful flash storage solutions for everyone from students, gamers, and home offices to the largest enterprises and public clouds to capture, preserve, access, and transform an ever-increasing diversity of data. The Company operates primarily in the United States (“U.S.”) and internationally, with a significant concentration in the Asia Pacific region.

On October 30, 2023, our parent company, Western Digital Corporation (collectively “WDC” or “Parent”), announced that its board of directors (“WDC Board of Directors”) authorized management to pursue a plan to separate the Company into an independent public company. The separation received final approval by the WDC Board of Directors and was completed on February 21, 2025.

WDC executed the spin-off of the Company through WDC’s pro rata distribution of 80.1% of the outstanding shares of common stock of the Company to holders of WDC’s common stock. Each WDC stockholder received one-third (1/3) of one share of the Company’s common stock for each share of WDC’s common stock held by such WDC stockholder as of February 12, 2025, the record date of the distribution. Upon completion of the separation, WDC owned 19.9% of the shares of the Company’s common stock, which WDC is expected to retain for a period of up to 12 months following the distribution.

The completion of the spin-off was subject to certain conditions as described in our Registration Statement on Form 10, initially filed with the U.S. Securities and Exchange Commission (“SEC”) on November 25, 2024, and as further amended thereafter and declared effective on January 31, 2025 (as amended, the “Form 10”).

In connection with the spin-off, the Company entered into or adopted several agreements that provide a framework for the relationships between the Company and WDC. See Note 9, Related Parties and Related Commitments and Contingencies, of the Notes to the Combined Financial Statements.

The accounting policies followed by the Company are set forth in Note 1, Organization and Basis of Presentation, of the Notes to the Combined Financial Statements for the year ended June 28, 2024, included in Exhibit 99.1 to our Form 10.

Unaudited Interim Financial Information

The Company has prepared the accompanying Condensed Combined Financial Statements pursuant to the rules and regulations of the SEC for interim financial reporting. These Condensed Combined Financial Statements are unaudited and, in our opinion, include all adjustments, consisting of normal recurring adjustments and accruals necessary for a fair presentation of our operations, financial position, and cash flows for the periods presented. Operating results for the periods presented are not necessarily indicative of the results that may be expected for the full fiscal year due to seasonal and other factors. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been omitted in accordance with the rules and regulations of the SEC. These Condensed Combined Financial Statements should be read in conjunction with the Company’s audited Combined Financial Statements and accompanying notes for the year ended June 28, 2024, included above.

NOTES TO CONDENSED COMBINED FINANCIAL STATEMENTS

Basis of Presentation

Throughout the periods covered by the Condensed Combined Financial Statements, the Company was an operating segment of WDC. Consequently, stand-alone interim financial statements were not historically prepared for the Company. The accompanying Condensed Combined Financial Statements have been prepared from WDC’s historical consolidated interim financial statements and accounting records and are presented on a stand-alone basis as if the Company’s operations had been conducted independently from WDC. The Company utilized allocations and carve-out methodologies to prepare these historic Condensed Combined Financial Statements. The Condensed Combined Financial Statements include the historical results of operations, financial position, and cash flows of the Company in accordance with GAAP, and the Company has adopted accounting policies and practices that are generally accepted in the industry in which it operates. As no single legal entity of the Company had a controlling financial interest in all other legal entities as of the reporting date, Condensed Combined Financial Statements have been prepared.

Intercompany transactions have been eliminated. With the exception of balances associated with lending arrangements reflected within Notes due to (from) Parent in the Condensed Combined Balance Sheets, transactions between the Company and WDC are generally considered to be effectively settled in the Condensed Combined Financial Statements at the time the transactions are recorded. The total net effect of the settlement of these transactions is reflected in the Condensed Combined Statements of Cash Flows as a financing activity and in the Condensed Combined Balance Sheets as Parent company net investment. General financing activities include the net impact of any cash movements resulting from WDC’s centralized treasury cash management.

The Condensed Combined Balance Sheets include all assets and liabilities that are specifically identifiable or otherwise attributable to the Company. Assets and liabilities shared between the Company and WDC are included in the stand-alone financial statements to the extent the asset is primarily used by the Company. If the Company is not the primary user of the asset, it is excluded entirely from the Condensed Combined Financial Statements. WDC has historically used a centralized approach to cash management and financing of its operations, as needed. Certain of our cash was transferred to WDC according to centrally managed cash programs by treasury, and WDC funded our operating and investing activities as needed. Cash transfers to and from WDC’s cash management accounts are reflected as a component of the Parent company net investment in the Condensed Combined Balance Sheets. Cash and cash equivalents in our Condensed Combined Balance Sheets primarily represent cash held locally by entities included in our Condensed Combined Financial Statements.

None of the debt obligations of WDC or corresponding interest expense have been included in the accompanying Condensed Combined Financial Statements, as the Company is neither the legal obligor nor transferee for any portion of such debt. WDC’s debt obligations were secured by a lien on substantially all assets and properties of WDC and certain key subsidiaries, which included assets and properties of the Company prior to the completion of the separation.

The Condensed Combined Statements of Operations and Comprehensive Income (Loss) include all revenues and costs directly attributable to the Company as well as an allocation of expenses related to facilities, functions and services provided by WDC. Allocation of general corporate expenses from WDC include, but are not limited to, executive management, finance, tax, legal, information technology, employee benefits administration, treasury, risk management, procurement, and other shared services. These corporate expenses have been allocated to the Company based on direct usage or benefit, where identifiable, with the remainder allocated based on headcount, revenue, or other relevant measures. The allocated costs are deemed to be settled between the Company and WDC in the period in which the expense was recorded in the Condensed Combined

NOTES TO CONDENSED COMBINED FINANCIAL STATEMENTS

(Unaudited)

Statements of Operations. The Condensed Combined Statements of Cash Flows present these corporate expenses as cash flows from operating activities, as these costs were incurred by WDC on our behalf. We consider these allocations to be a reasonable reflection of the utilization of services by, or the benefits provided to, the Company. The allocations may not, however, reflect the expense the Company would have incurred as a stand-alone company for the periods presented. Additionally, these costs may not be indicative of the expenses that the Company will incur in the future or would have incurred if the Company had obtained these services from an unrelated third party. It is not practicable to estimate the actual costs that would have been incurred had the Company been a stand-alone company during the periods presented. The actual costs that may have been incurred would depend on a number of factors, including the chosen organizational structure, whether functions were outsourced or performed by employees, and decisions with respect to areas such as facilities, information technology, and operating infrastructure.

WDC maintains various stock-based compensation plans at a corporate level. Employees of the Company participated in those programs and a portion of the compensation cost associated with those plans is included in the Company’s Condensed Combined Statements of Operations for the periods presented in this interim financial information. Stock-based compensation expense has been included within Parent company net investment. The amounts presented in the Condensed Combined Financial Statements are not necessarily indicative of future awards and may not reflect the results that the Company would have experienced as a stand-alone entity.

Current and deferred income taxes and related tax expenses have been determined based on the stand-alone results of the Company by applying Accounting Standards Codification No. 740, Income Taxes, to the Company’s operations in each country as if it were a separate taxpayer (i.e., following the “Separate Return Methodology”).

Fiscal Year

The Company’s fiscal year ends on the Friday nearest to June 30 and typically consists of 52 weeks. Approximately every five to six years, we report a 53-week fiscal year to align the fiscal year with the foregoing policy. Fiscal year 2025, which will end on June 27, 2025, and fiscal year 2024, which ended on June 28, 2024, are each comprised of 52 weeks, with all quarters presented consisting of 13 weeks. Unless otherwise indicated, references herein to specific years and quarters are to fiscal years and fiscal quarters, and references to financial information are on a condensed combined basis.

Segment Reporting

Operating segments are components of an enterprise for which separate financial information is available and are evaluated regularly by the Company’s Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources and in assessing performance. The Company currently operates as both a single operating and reportable segment.

Business Separation Costs

On October 30, 2023, WDC announced that its Board of Directors had completed its strategic review and, after evaluating a comprehensive range of alternatives, authorized WDC to pursue a plan to separate its flash business from its hard disk drive business to create two independent public companies. As a result of the plan, the Company has incurred separation and transition costs related to the completion of its separation from WDC. The separation and transition costs are recorded within Business separation costs in the Condensed Combined Statements of Operations.

Use of Estimates

Management has made estimates and assumptions relating to the reporting of certain assets and liabilities in conformity with U.S. GAAP. These estimates and assumptions have been applied using methodologies that are consistent throughout the periods presented, with consideration given to the potential impacts of current macroeconomic conditions. However, actual results could differ materially from these estimates.

Note 2. Recent Accounting Pronouncements

Accounting Pronouncements Recently Adopted

In September 2022, the Financial Accounting Standards Board (“FASB”) issued an accounting standards update (“ASU”) No. 2022-04, “Liabilities-Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations,” which requires annual and interim disclosures for entities that use supplier finance programs in connection with the purchase of goods and services. The ASU requires the Company to provide disclosure of outstanding obligations to such suppliers for all balance sheet dates presented beginning with the Company’s first quarter of 2024 and to provide certain annual roll-forward information related to those obligations beginning with the Company’s first fiscal quarter of 2025. The ASU does not affect the recognition, measurement or financial statement presentation for supplier finance program obligations. The Company adopted the guidance on the first day of fiscal year 2024, and the adoption did not have a material impact on its Condensed Combined Financial Statements. As of December 27, 2024, none of the Company’s suppliers are utilizing these programs.

Recently Issued Accounting Pronouncements Not Yet Adopted

In November 2023, the FASB issued ASU No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures,” which expands on segment reporting requirements primarily through enhanced disclosures surrounding significant segment expenses. The ASU expands on existing segment reporting requirements to require that a public entity disclose, on an annual and interim basis, significant segment expenses that are regularly provided to an entity’s CODM, a description of other segment items by reportable segment, and any additional measures of a segment’s profit or loss used by the CODM when deciding how to allocate resources. These incremental disclosures will be required beginning with the Company’s financial statements for the year ending June 27, 2025. The Company is currently assessing these reporting requirements and expects to provide any required disclosures at that time.

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The ASU calls for enhanced income tax disclosure requirements surrounding the tabular rate reconciliation and income taxes paid. The Company is currently compiling the information required for these disclosures. These incremental disclosures will be required beginning with the Company’s financial statements for the year ending June 26, 2026, with early adoption permitted. The Company expects to provide any required disclosures at that time.

In November 2024, the FASB issued ASU 2024-03, “Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses,” which is intended to improve disclosures about the expenses of public entities. The new guidance requires more detailed information about the types of expenses in commonly presented expense captions (such as cost of sales and selling, general and administrative expenses) and requires public entities to disclose, on an annual and interim basis, the amounts of expenses included in each relevant expense caption presented on the face of the income

statement within continuing operations, in a tabular format. Additionally, public entities will be required to disclose a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively, the total amount of selling expenses, and, in annual reporting periods, the definition of selling expenses. This standard is effective on either a prospective or retrospective basis for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The Company is currently compiling the information required for these disclosures and assessing the basis of adoption and expects to adopt the guidance for annual reporting periods included in the Company’s financial statements for the year ending June 30, 2028.

Note 3. Geographic Information and Concentrations of Risk

Disaggregated Revenue

The Company’s broad portfolio of technology and products addresses multiple end markets. Cloud represents a large and growing end market comprised primarily of products for public or private cloud environments and enterprise customers. Through the Client end market, the Company provides its original equipment manufacturer (“OEM”) and channel customers a broad array of high-performance flash solutions across personal computer, mobile, gaming, automotive, virtual reality headsets, at-home entertainment, and industrial spaces. The Consumer end market is highlighted by the Company’s broad range of retail and other end-user products, which capitalize on the strength of the Company’s product brand recognition and vast points of presence around the world.

The Company’s disaggregated revenue information was as follows:

|  | Six Months Ended |
|  | December 27, 2024 |  |  | December 29, 2023 |
|  | (in millions) |
Revenue by end market |  |  |  |  |  |  |  |
Cloud |  | $ | 550 |  |  | $ | 58 |

Consumer |  |  | 1,112 |  |  |  | 1,173 |
Total revenue |  | $ | 3,759 |  |  | $ | 3,198 |
Revenue by geography |  |  |  |  |  |  |  |

Europe, Middle East and Africa |  |  | 691 |  |  |  | 538 |
Total revenue |  | $ | 3,759 |  |  | $ | 3,198 |

The Company’s top 10 customers accounted for 46% of its net revenue for the six months ended December 27, 2024, and 43% of its net revenue for the six months ended December 29, 2023. For the six months ended December 27, 2024, no customer accounted for more than 10% of the Company’s net revenue. For the six months ended December 29, 2023, one customer accounted for 10% of the Company’s net revenue.

Note 4. Revenues

Contract assets represent the Company’s rights to consideration where performance obligations are completed, but the customer payments are not due until another performance obligation is satisfied. The

Company did not have any contract assets as of December 27, 2024, or June 28, 2024. Contract liabilities relate to customers’ payments in advance of performance under the contract and primarily relate to remaining performance obligations under professional service and support and maintenance contracts. Contract liabilities as of December 27, 2024 and June 28, 2024, and changes in contract liabilities for the six months ended December 27, 2024 and December 29, 2023, were not material.

The Company incurs sales commissions as direct incremental costs to obtain sales contracts. The Company has applied the practical expedient to recognize sales commissions as an expense when incurred if the amortization period is expected to be one year or less or the amount is not material, with these costs charged to Selling, general and administrative expenses. The Company had no other direct incremental costs to obtain contracts that have an expected benefit of greater than one year.

The Company applies the practical expedients and does not disclose the transaction price allocated to the remaining performance obligations for (i) arrangements with an original expected duration of one year or less, mainly consisting of professional service, support, and maintenance contracts, and (ii) variable consideration for sale-based or usage-based royalties for intellectual property license arrangements, which typically range longer than one year. The remaining performance obligations are mainly attributed to right-to-access patent license arrangements, professional service arrangements and customer support and service contracts, which will be recognized over their contract period. The transaction price allocated to the remaining performance obligations as of December 27, 2024, was not material.

Note 5. Supplemental Financial Statement Data

Goodwill

The following table provides a summary of goodwill activity for the period presented:

|  | (in millions) |
Balance at June 28, 2024 |  | $ | 7,207 |
Divestiture (1) |  |  | (382 | )
Balance at December 27, 2024 |  | $ | 6,825 |

(1) | On September 28, 2024, the Company sold its majority interest in a subsidiary. See further discussion in Part 1, Item 1, Note 9, Related Parties and Related Commitments and Contingencies.

Goodwill attributed to the Company represents the historical goodwill balances in WDC’s business arising from acquisitions specific to the Company.

The Company determined that its single operating segment was also its single reporting unit. Goodwill is not amortized. Instead, it is tested for impairment annually as of the beginning of the Company’s fourth quarter or more frequently if events or changes in circumstances indicate that goodwill may be impaired. The Company uses qualitative factors to determine whether goodwill is more likely than not impaired and whether a quantitative test for impairment is considered necessary. If the Company concludes from the qualitative assessment that goodwill is more likely than not impaired, the Company is required to perform a quantitative approach to determine the amount of impairment.

The Company is required to use judgment when assessing goodwill for impairment, including evaluating the impact of industry and macroeconomic conditions and the determination of the fair value of the reporting unit. In

F-53

NOTES TO CONDENSED COMBINED FINANCIAL STATEMENTS

(Unaudited)

addition, the estimates and assumptions used to determine the fair value as well as the actual carrying value may change based on future changes in the Company’s results of operations, macroeconomic conditions or other factors. Changes in these estimates and assumptions could materially affect the Company’s assessment of the fair value and goodwill impairment. In addition, if negative macroeconomic conditions continue or worsen, goodwill could become impaired, which could result in an impairment charge and materially adversely affect the Company’s financial condition and results of operations.

For the six months ended December 29, 2023, there were no impairment charges recorded. In the six months ended December 27, 2024, the Company identified macroeconomic conditions and other qualitative factors indicating a potential impairment of goodwill at December 27, 2024. The Company conducted a quantitative analysis of the fair value of its sole reporting unit to determine the existence and magnitude of any potential goodwill impairment. The quantitative analysis employed a weighted valuation model, assessing the fair value of the reporting unit using both income and market approaches.

The income approach valued the projected discounted cash flows that are expected to be generated by the Company’s reporting unit and required judgments and estimates surrounding general economic conditions and company-specific performance inputs such as revenue growth rates, gross margins, operating costs, capital expenditures, assumed tax rates and other assumptions deemed reasonable by management. The market approach valued the reporting unit based upon financial performance and market multiples of comparable public companies, including consideration of a control premium representing the estimated amount a market participant would pay to obtain a controlling interest in the Company. After completion of the quantitative analysis, the Company determined that the fair value of its reporting unit exceeded its carrying value by 12%, resulting in no impairment charges recorded in the three and six months ended December 27, 2024. See Note 15, Subsequent Events, for information about a potential impairment of goodwill for the three months ended March 28, 2025.

Accounts receivable, net

From time to time, in connection with factoring agreements, WDC sells certain of our trade accounts receivable without recourse to third-party purchasers in exchange for cash. During the six months ended December 27, 2024, there were no trade accounts receivable of the Company sold by WDC. During the six months ended December 29, 2023, WDC sold trade accounts receivable of the Company and received cash proceeds of $272 million. The discounts on the trade accounts receivable sold during the period were not material and were recorded within Other expense, net in the Condensed Combined Statements of Operations. There were no factored receivables outstanding as of December 27, 2024 and June 28, 2024.

Note 6. Fair Value Measurements and Investments

Financial Instruments Carried at Fair Value

Financial assets and liabilities that are remeasured and reported at fair value at each reporting period are classified and disclosed in one of the following three levels:

Level 1. Quoted prices in active markets for identical assets or liabilities.

Level 2. Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3. Inputs that are unobservable for the asset or liability and that are significant to the fair value of the assets or liabilities.

As of December 27, 2024, and June 28, 2024, the Company had accounts payable balances due to Flash Ventures of $252 million and $313 million, respectively.

The Company’s maximum reasonably estimable loss exposure (excluding lost profits) as a result of its involvement with Flash Ventures, based upon the Japanese yen to U.S. dollar exchange rate at December 27, 2024, is presented below. Investments in Flash Ventures are denominated in Japanese yen, and the maximum estimable loss exposure excludes any cumulative translation adjustment due to revaluation from the Japanese yen to the U.S. dollar.

The Company is obligated to pay for variable costs incurred in producing its share of Flash Ventures’ flash-based memory wafer supply, based on its rolling three-month forecast, which generally equals 50% of Flash Ventures’ output. In addition, the Company is obligated to pay for half of Flash Ventures’ fixed costs regardless of the output the Company chooses to purchase. The Company is not able to estimate its total wafer purchase commitment obligation beyond its rolling three-month purchase commitment because the price is determined by reference to the future cost of producing the semiconductor wafers. In addition, the Company is committed to fund 49.9% to 50.0% of each Flash Ventures entity’s capital investments to the extent that the Flash Ventures entity’s operating cash flow is insufficient to fund these investments.

Flash Ventures has historically operated nearly 100% of its manufacturing capacity. During the three and six months ended December 29, 2023, as a result of flash market conditions, the Company temporarily reduced its utilization of its share of Flash Ventures’ manufacturing capacity to an abnormally low level to more closely align the Company’s flash-based wafer supply with projected demand. During the six months ended December 29, 2023, the Company incurred costs of $249 million associated with the reduction in utilization related to Flash Ventures, which was recorded as a charge to Cost of revenue. No such charges were incurred during the six months ended December 27, 2024.

The Company has facility agreements with Kioxia related to the construction and operation of Kioxia’s 300-millimeter wafer fabrication facility in Kitakami, Japan, referred to as “K1”, a wafer fabrication facility in Yokkaichi, Japan, referred to as “Y7”, and a wafer fabrication facility in Kitakami, Japan, referred to as “K2”. In connection with the construction of these facilities, the Company makes prepayments toward future building depreciation. In connection with the start-up of the K1, Y7 and K2 facilities, the Company has made prepayments over time, and as of December 27, 2024, $944 million, with $124 million recorded within Other current assets and $840 million recorded within Other non-current assets in the Condensed Combined Balance Sheets, remain to be credited against future building depreciation charges. As of December 27, 2024, the Company is also committed to making additional building depreciation prepayments of $303 million, based on the Japanese yen to U.S. dollars exchange rate of ¥157.86 as of such date, payable as follows: $60 million for the remaining of fiscal year 2025, $30 million in fiscal year 2026, $111 million in fiscal year 2027, $89 million in fiscal year 2028 and $13 million in fiscal year 2029. As of December 27, 2024, in addition to the requirements to make building depreciation prepayments, the Company will also make payments for building depreciation of approximately $107 million at varying dates through fiscal year 2035.

The Company has not made any indemnification payments nor recorded any indemnification receivables under any such agreements. As of December 27, 2024, no amounts have been accrued in the Condensed Combined Financial Statements with respect to these indemnification agreements.

Unis Venture

WDC also has a venture with Unisplendour Corporation Limited and Unissoft (Wuxi) Group Co. Ltd. (“Unis”), referred to as the “Unis Venture,” to market and sell the Company’s products in China and to develop data storage systems for the Chinese market in the future. On January 24, 2025, the Company and WDC entered into an equity transfer agreement (the “Equity Transfer Agreement”) to transfer WDC’s entire equity interest in the Unis Venture to us. Therefore, subsequent to the end of the second quarter of fiscal 2025, the Unis Venture will be minority owned by the Company and majority-owned by Unis.

Prior to the execution of the Equity Transfer Agreement, the Unis Venture was not historically managed as a component of the Company and as such, the related equity method investment is not reflected within our Condensed Combined Financial Statements. For the six months ended December 27, 2024, and December 29, 2023, the Company recognized approximately 1% and 1%, respectively, of its combined revenue on products distributed by the Unis Venture. The outstanding accounts receivable due from the Unis Venture were 1% and 4% of Accounts receivable, net, as of December 27, 2024 and June 28, 2024, respectively.

Sale of a Majority Interest in a Subsidiary

In March 2024, SanDisk China Limited (“SanDisk China”), an indirect wholly-owned subsidiary of WDC, entered into an equity purchase agreement to sell 80% of its equity interest in SanDisk Semiconductor (Shanghai) Co. Ltd. (“SDSS”) an indirect wholly-owned subsidiary of WDC which holds one of the Company’s manufacturing facilities, to JCET Management Co., Ltd. (“JCET”), a wholly-owned subsidiary of JCET Group Co., Ltd., a Chinese publicly-listed company, thereby forming a venture between SanDisk China and JCET (the “Transaction”). The venture aims to provide independent semiconductor assembly, testing, and other related services in the People’s Republic of China for customers including, but not limited to, the Company and its affiliates.

The Transaction closed on September 28, 2024, and SanDisk China completed the sale of 80% of its equity interest in SDSS to JCET.

Proceeds from the sale, including working capital adjustments, were $659 million (pre-tax). On October 1, 2024, the Company received an initial pre-tax installment of $262 million. On January 6, 2025, the Company received a second pre-tax installment of $210 million and expects to receive remaining pre-tax proceeds of $187 million in five installments of approximately $37 million on September 28 of each year through September 28, 2029. As of December 27, 2024, the outstanding consideration receivable was recognized at its present value of $370 million, with $243 million classified as Other current assets and $127 million classified as Other non-current assets in the Condensed Combined Balance Sheets. The present value discount of $27 million as of December 27, 2024 will be recognized using the effective interest method over the next five years as Interest income in the Condensed Combined Statements of Operations.

The Company’s 20% retained interest in SDSS was determined to be valued at $158 million based on the fair value of the total pre-tax consideration received and receivable from JCET for its purchase of its 80% interest in SDSS. The Company accounts for its 20% interest in SDSS as an equity method investment within Other non-current assets in the Condensed Combined Balance Sheets. The Company’s 20% interest in the earnings of SDSS will be recognized one quarter in arrears and will be reported in Other expense, net in the Condensed Combined Statements of Operations.

The Transaction resulted in a pre-tax gain of $34 million, calculated as the difference between the total consideration for the sale, including the outstanding consideration receivable and the fair value of the Company’s

20% retained interest, less the carrying value of the net assets divested, which included, among other items, $71 million of cash and cash equivalents and $382 million of goodwill allocated to SDSS.

Subsequent to and in connection with the Transaction, Western Digital Technologies, Inc. (“WDT”) entered into a five-year supply agreement with SDSS (the “Supply Agreement”) to purchase certain flash-based products with a minimum annual commitment of $550 million (the “minimum annual commitment”). On January 10, 2025, the Company and WDT entered into an assignment agreement, pursuant to which, WDT assigned all of its rights and obligations under the Supply Agreement to the Company. The Supply Agreement contains specific penalties the Company must pay if SDSS fails to meet its minimum annual commitment. The Supply Agreement also provides that if SDSS purchases exceed the minimum annual commitment in any of the two years immediately succeeding any annual period where a shortfall penalty has been paid, SDSS shall reimburse the Company an amount not exceeding the previously paid penalty amount. The Supply Agreement expires on September 28, 2029, and automatically renews for additional one-year terms unless earlier terminated by either of the parties. The Company also entered into an agreement to grant SDSS certain intellectual property rights on a royalty-free basis for use in manufacturing products on the Company’s behalf for the term of and under the Supply Agreement. For the six months ended December 27, 2024, the Company made purchases of $111 million under the Supply Agreement and had an accounts payable balance due to SDSS of $117 million as of December 27, 2024.

The Company also entered into an arrangement to provide certain transition services for a limited period following the closing of the Transaction. Charges under this arrangement were not material.

Allocation of Corporate Expenses

WDC has provided various corporate services to the Company in the ordinary course of business, including executive management, finance, tax, legal, information technology, employee benefits administration, treasury, risk management, procurement and other shared services. These corporate expenses have been allocated to the Company based on direct usage or benefit, where identifiable, with the remainder allocated based on headcount, revenue or other relevant measures. Management believes the basis on which the expenses have been allocated to be a reasonable reflection of the utilization of services provided to or the benefit received by us.

Effective at the beginning of the second quarter of fiscal year 2025, the Company was operationally separated from the operations that were ultimately retained by WDC following completion of the spin-off transaction. In connection with this operational separation, personnel serving the Company in shared service functions were transferred into legal entities dedicated to the Company, and substantially all assets, liabilities, and contracts pertaining to operations of the Company were transferred to legal entities dedicated to the Company as well. Accordingly, there was a substantial reduction in the pool of shared corporate overhead costs of WDC that were subject to allocation in the second quarter of fiscal year 2025.

Leases

The Company leases certain domestic and international facilities and data center space under long-term, non-cancelable operating leases that expire at various dates through fiscal year 2039. These leases include no material variable or contingent lease payments. Operating lease assets and liabilities are recognized based on the present value of the remaining lease payments discounted using the Company’s incremental borrowing rate. Operating lease assets also include prepaid lease payments minus any lease incentives. Extension or termination options present in the Company’s lease agreements are included in determining the right-of-use asset and lease liability when it is reasonably certain the Company will exercise those options. Lease expense is recognized on a straight-line basis over the lease term.

Sale-Leaseback

In September 2023, WDC completed a sale and leaseback of its facility in Milpitas, California and received net proceeds of $191 million in cash. A substantial majority of these assets are associated with the Company, and as a result, $134 million of the net proceeds from the sale-leaseback transaction has been allocated to us on a relative square footage basis and reflected as a cash inflow from investing activities within the Condensed Combined Statements of Cash Flows for the six months ended December 29, 2023. In connection with the sale and leaseback, the Company recorded a gain of $60 million upon the closing of the transaction. For more information, see Note 13, Employee Termination and Other Charges of the Notes to Condensed Combined Financial Statements.

The property is being leased back to the Company at a total annual rate of $16 million for the first year and increasing by 3% per year thereafter through January 1, 2039. The lease includes three five-year renewal options and one four-year renewal option for the ability to extend through December 2057. The associated operating lease liability and right-of-use asset for this facility has been included in the Condensed Combined Balance Sheets as of December 27, 2024 and June 28, 2024. This facility is utilized in the Company’s operations, and the total lease expense has been allocated to the Company based on the continued usage of the facility.

Purchase Agreements and Other Commitments

In the normal course of business, the Company enters into purchase orders with suppliers for the purchase of components used to manufacture its products. These purchase orders generally cover forecasted component supplies needed for production during the coming months, are recorded as a liability upon receipt of the components, and generally may be changed or canceled at any time prior to shipment of the components. The Company also enters into long-term agreements with suppliers that contain fixed future commitments, which are contingent upon certain conditions such as performance, quality and technology of the vendor’s components. As of December 27, 2024, the Company had the following minimum long-term commitments:

|  | Long-term commitments |
|  | (in millions) |

Remaining six months of 2025 |  | $ | 26 |

Note 11. Stock-based Compensation Expense

The table below summarizes the total costs charged to the Company related to the Company’s employees’ participation in WDC’s equity incentive plan during the periods presented:

|  | Six Months Ended |
|  | December 27, 2024 |  |  | December 29, 2023 |

Total |  | $ | 89 |  |  | $ | 77 |

The total unrecognized stock-based compensation expense associated with our employees was $303 million as of December 27, 2024. The total unrecognized stock-based expense relates to employees of WDC who will be employees of the Company after the separation.

Note 12. Income Tax Expense

The Tax Cuts and Jobs Act (the “2017 Act”), enacted on December 22, 2017, includes a broad range of tax reform proposals affecting businesses. WDC completed its accounting for the tax effects of the enactment of the 2017 Act during the second quarter of 2019. However, the U.S. Treasury and the Internal Revenue Service have issued tax guidance on certain provisions of the 2017 Act since the enactment date, and the Company anticipates the issuance of additional regulatory and interpretive guidance. WDC applied a reasonable interpretation of the 2017 Act along with the then-available guidance in finalizing its accounting for the tax effects of the 2017 Act. Any additional regulatory or interpretive guidance would constitute new information, which may require further refinements to the Company’s estimates in future periods.

On August 16, 2022, President Biden signed into law the Inflation Reduction Act of 2022, which contained significant changes to laws related to tax, climate, energy, and health care. The tax measures include, among other things, a corporate alternative minimum tax (“CAMT”) of 15% on corporations with three-year average annual adjusted financial statement income (“AFSI”) exceeding $1.0 billion. The CAMT was effective for the Company beginning with fiscal year 2024. The Company does not expect to be subject to the CAMT of 15% for fiscal year 2025 as its average annual AFSI did not exceed $1.0 billion for the preceding three-year period.

On December 20, 2021, the Organization for Economic Co-operation and Development G20 (“OECD/G20”) Inclusive Framework on Base Erosion and Profit Shifting released Model Global Anti-Base Erosion rules under Pillar Two (“Pillar Two”). Several non-U.S. jurisdictions have either enacted legislation or announced their intention to enact future legislation to adopt certain or all components of the Pillar Two, some of which are effective for the Company in fiscal year 2025. For fiscal year 2025, the Company currently expects to be able to

meet certain transitional safe harbors and does not expect any material Pillar Two taxes. As more jurisdictions adopt this legislation in fiscal year 2026, there may be material increases in the Company’s future tax obligations in certain jurisdictions.

The following table presents the Company’s Income tax expense and the effective tax rate:

|  | Six Months Ended |
|  | December 27, 2024 |  |  | December 29, 2023 |
|  | ($ in millions) |
Income (loss) before taxes |  | $ | 440 |  |  | $ | (754 | )
Income tax expense |  |  | 125 |  |  |  | 65 |
Effective tax rate |  |  | 28 | % |  |  | (9 | )%

Beginning in fiscal year 2023, the 2017 Act requires the Company to capitalize and amortize R&D expenses rather than expensing them in the year incurred. The tax effects related to the capitalization of R&D expenses are included in the effective tax rate for the six months ended December 27, 2024 and December 29, 2023.

The relative mix of earnings and losses by jurisdiction, the deduction for foreign-derived intangible income, credits and tax holidays in Malaysia that have or will expire at various dates during years 2025 through 2031 resulted in decreases to the effective tax rate below the U.S. statutory rate for the six months ended December 27, 2024. However, the tax effects of the mandatory capitalization of R&D expenses offset these decreases, resulting in the effective tax rate being closer to the U.S. Federal statutory rate for the six months ended December 27, 2024.

The primary drivers of the difference between the effective tax rate for the three and six months ended December 29, 2023 and the U.S. Federal statutory rate of 21% are the relative mix of earnings and losses by jurisdiction, the deduction for foreign-derived intangible income, credits and tax holidays in Malaysia.

Uncertain Tax Positions

With the exception of certain unrecognized tax benefits that are directly associated with the tax position taken, unrecognized tax benefits are presented gross in the Condensed Combined Balance Sheets.

The following is a tabular reconciliation of the total amounts of unrecognized tax benefits, excluding accrued interest and penalties for the six months ended December 27, 2024:

|  | (in millions) |
Accrual balance at June 28, 2024 |  | $ | 47 |
Gross increases related to prior year tax positions |  |  | 17 |
Gross increases related to current year tax positions |  |  | 3 |
Gross decrease related to prior year tax positions |  |  | (7 | )
Accrual balance at December 27, 2024 |  | $ | 60 |

As of December 27, 2024 and June 28, 2024, the liability for unrecognized tax benefits (excluding accrued interest and penalties) was $60 million and $47 million, respectively. Interest and penalties related to unrecognized tax benefits are recognized in liabilities recorded for uncertain tax positions and are recorded in the provision for income taxes. Accrued interest and penalties included in the Company’s liability related to unrecognized tax benefits as of December 27, 2024 and June 28, 2024 was $6 million and $9 million, respectively.

The Company believes that adequate provision has been made for any adjustments that may result from any other tax examinations. However, the outcome of such tax examinations cannot be predicted with certainty. If any issues addressed in the Company’s tax examinations are resolved in a manner not consistent with management’s expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs. Any significant change in the amount of the Company’s liability for unrecognized tax benefits would most likely result from additional information relating to the examination of the Company’s tax returns.

Note 13. Employee Termination and Other Charges

Business Realignment

The Company periodically incurs charges to realign its operations with anticipated market demand, primarily consisting of organization rationalization designed to streamline its business, reduce its cost structure and focus its resources. The Company has taken actions to reduce the amount of capital invested in facilities, including the sale-leaseback of its facility in Milpitas, California, in September 2023, as discussed in Note 10, Leases and Other Commitments of the Notes to Condensed Combined Financial Statements.

The Company recorded the following net charges related to these actions for the periods presented:

|  | Six Months Ended |
|  | December 27, 2024 |  |  | December 29, 2023 |
|  | (in millions) |
Employee termination benefits |  | $ | 2 |  |  | $ | 14 |
Contract termination and other |  |  | 3 |  |  |  | — |
Gain on sale-leaseback of facility |  |  | — |  |  |  | (60 | )
Total employee termination and other charges |  | $ | 5 |  |  | $ | (46 | )

The termination benefits accrual balance as of December 27, 2024 and the periodic activity during the six months ended December 27, 2024 were not material.

Note 14. Legal Proceedings

In the normal course of business, the Company is subject to legal proceedings, lawsuits and other claims. Although the ultimate aggregate amount of reasonably possible monetary liability or financial impact with respect to these other matters is subject to many uncertainties, management believes that any monetary liability or financial impact to the Company from these matters, individually and in the aggregate, would not be material to the Company’s financial condition, results of operations or cash flows. However, any monetary liability and financial impact to the Company from these matters could differ materially from the Company’s expectations.

On February 21, 2025, the Company completed its spin-off from WDC (the “Spin-Off”) through WDC’s pro rata distribution of 80.1% of the outstanding shares of common stock of the Company to WDC’s existing stockholders. Each of WDC’s stockholders received one-third (1/3) of one share of the Company’s common stock for each share of WDC’s common stock held by such WDC stockholder as of February 12, 2025, the record date of the distribution. Upon completion of the Spin-Off, WDC owned 19.9% of the outstanding shares of the Company’s common stock, which WDC is expected to retain for a period of up to 12 months following the separation. The Company is also subject to various agreements with WDC in connection with the separation. On February 24, 2025, the Company began trading as an independent, publicly traded company under the stock symbol “SNDK” on the Nasdaq Stock Market LLC (“Nasdaq”).

In connection with, and as of the closing date of the Spin-Off, on February 21, 2025, the Company entered into definitive agreements with WDC that set forth the terms and conditions of the Spin-Off and provide a framework for WDC’s relationship with the Company following the Spin-Off. These agreements include the Separation and Distribution Agreement (as described below), which contains certain key provisions related to the Spin-Off, as well as a Transition Services Agreement, a Tax Matters Agreement, an Employee Matters Agreement, an Intellectual Property Cross-License Agreement, a Transitional Trademark License Agreement, and a Stockholder and Registration Rights Agreement, as described in and filed as Exhibits to the Company’s Current Report on Form 8-K on February 24, 2025. Additionally, the Company adopted certain compensation plans, which were filed as Exhibits to our Form 10.

Loan Agreement

On February 21, 2025, the Company entered into a Loan Agreement (the “Loan Agreement”) by and among the Company, the lenders party thereto, JPMorgan Chase Bank, N.A., as administrative agent and collateral agent and the other parties party thereto. The Loan Agreement comprises a term loan B facility in the principal amount of $2 billion (the “Term Loan Facility”) and a revolving credit facility in the principal amount of $1.5 billion (the “Revolving Credit Facility” and together with the Term Loan Facility, the “Facilities”). The Term Loan Facility bears interest, at the Company’s option, at (x) the Adjusted Term SOFR Rate (as defined in the Loan Agreement) plus an interest rate margin of 3.00% per annum or (y) a base rate plus an interest rate margin of 2.00% per annum. The Term Loan Facility will mature on February 20, 2032, and amortizes at 1.00% per annum.

Borrowings under the Revolving Credit Facility, for U.S. dollar borrowings, will bear interest, at the Company’s option, at (x) the Adjusted Term SOFR Rate (as defined in the Loan Agreement), which rate includes a credit spread adjustment of 0.10%, plus an interest rate margin of 2.00% per annum (subject to step-ups based on the Company’s Leverage Ratio (as defined in the Loan Agreement)), or (y) a base rate plus an interest rate margin of 1.00% per annum (subject to step-ups based on the Company’s Leverage Ratio (as defined in the Loan Agreement)). The Company will pay a commitment fee of 0.30% per annum (subject to step-ups based on the Company’s Leverage Ratio (as defined in the Loan Agreement)) in respect of undrawn revolving commitments under the Revolving Credit Facility. The Revolving Credit Facility will also provide for borrowings in Euros, Yen and additional currencies agreed to by the lenders under the Revolving Credit Facility. The Revolving Credit Facility will mature on February 21, 2030, at which time the commitments thereunder shall be terminated and will not have any amortization.

The obligations under the Loan Agreement are guaranteed by the Company’s wholly owned subsidiary, Sandisk Technologies, Inc. (“SDT”) and are required to be guaranteed by any of the Company’s future material U.S. wholly owned subsidiaries, subject to certain exceptions outlined in the Loan Agreement. The obligations under the Loan Agreement are secured by the Company’s assets and SDT’s assets and are required to be secured by the assets of any of the Company’s future material U.S. wholly owned subsidiaries, subject, in each case, to certain exceptions outlined in the Loan Agreement.

The Loan Agreement includes certain restrictions (subject to certain exceptions outlined in the Loan Agreement) on the ability of the Company and its subsidiaries to undertake certain activities, including to incur indebtedness and liens, merge or consolidate with other entities, dispose or transfer their assets, pay dividends or make distributions, make investments, make payments on junior or subordinated debt, enter into burdensome agreements or transact with affiliates. The Loan Agreement also includes a financial covenant, which is solely for the benefit of the lenders under the Revolving Credit Facility, that requires the Company to maintain a maximum Leverage Ratio (as defined in the Loan Agreement).

On February 21, 2025, the Company borrowed $2 billion under its Term Loan Facility. The Company used a portion of the proceeds of the borrowing to pay a dividend to WDC in the amount of approximately $1.5 billion, with the remainder to be used for general corporate purposes of the Company. The Revolving Credit Facility may be borrowed by the Company from time to time for general corporate purposes.

In connection with the Loan Agreement, the Company and SDT entered into a security agreement (the “Security Agreement”) to secure the obligations under the Facilities on a first-priority basis (subject to permitted liens) by a lien on substantially all the assets and properties of the Company and SDT, subject to certain exceptions.

In connection with the Loan Agreement, the Company (solely with respect to obligations of any additional Borrower under the Loan Agreement) and SDT entered into a guaranty agreement (the “Guaranty Agreement”) to secure and unconditionally guarantee the obligations under the Loan Agreement, respectively, in each case subject to certain exceptions.

The foregoing description of the Loan Agreement, Security Agreement and Guaranty Agreement do not purport to be complete and are subject to, and qualified in its entirety by, the full text of the Loan Agreement, Security Agreement and Guaranty Agreement.

Potential Impairment of Goodwill and Long-lived Assets

Subsequent to the completion of the separation, the Company identified potential impairment indicators related to the trading price of the Company’s common stock and a resulting market capitalization that was below its December 27, 2024 net book value. In accordance with Accounting Standards Codification No. 350, Intangibles - Goodwill and Other, the Company initiated a quantitative analysis of potential impairment of goodwill and long-lived assets. That analysis is ongoing, and the Company believes it is more likely than not that it will record an impairment charge in the three months ended March 28, 2025. See Note 5, Supplemental Financial Statement Data, for information about how goodwill is tested for impairment.

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 13. | Other Expenses of Issuance and Distribution.

The following table sets forth the costs and expenses payable by the registrant in connection with the issuance of the shares of our common stock being registered. The registrant has agreed with the selling stockholder to bear substantially all expenses (other than underwriting discounts and selling commissions) in connection with the registration and sale of the shares being registered. All amounts are estimates except the Securities and Exchange Commission registration fee and Financial Industry Regulatory Authority, Inc. (“FINRA”) fee.

* | Estimated fees and expenses (other than the SEC registration fee and FINRA filing fee) will depend on the number of securities offered, the number of issuances and the nature of the offerings, and cannot be estimated at this time.

Item 14. | Indemnification of Directors and Officers.

The registrant is a Delaware corporation. Section 102(b)(7) of the Delaware General Corporation Law (the “DGCL”) allows a corporation to provide in its certificate of incorporation that a director or officer of the corporation will not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except where the director or officer breached the duty of loyalty, failed to act in good faith, engaged in intentional misconduct or knowingly violated a law, authorized the payment of a dividend or approved a stock repurchase in violation of Delaware corporate law, obtained an improper personal benefit or, with respect to an officer only, in any action by or in the right of the corporation. Our certificate of incorporation provides for this limitation of liability.

Reference is also made to Section 145 of the DGCL, which provides that a corporation may indemnify any persons, including officers and directors, who are, or are threatened to be made, parties to any threatened, pending or completed legal action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation), by reason of the fact that such person is or was a director, officer, employee or agent of such corporation or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided such director, officer, employee or agent acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe that the person’s conduct was unlawful. A Delaware corporation may indemnify officers and directors in an action by or in the right of the corporation under the same conditions, except that no indemnification is permitted without judicial approval if the officer or director is adjudged to be liable to the corporation. Where an officer or director is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him or her against the expenses that such officer or director actually and reasonably incurred. The indemnification permitted under the DGCL is not exclusive, and a corporation is empowered to purchase and maintain insurance against liabilities whether or not indemnification would be permitted by statute.

II-1

##### Table of Contents

The Company’s bylaws provide that we must indemnify and advance expenses to our directors and officers to the full extent authorized by the DGCL.

We have entered into indemnification agreements with each of our directors and executive officers. Such agreements may require us, among other things, to advance expenses and otherwise indemnify our officers and directors against certain liabilities that may arise by reason of their status or service as officers or directors, to the fullest extent permitted by law. We intend to enter into indemnification agreements with any new directors and executive officers in the future.

The indemnification rights set forth above shall not be exclusive of any other right which an indemnified person may have or hereafter acquire under any statute, any provision of the Company’s certificate of incorporation, the Company’s bylaws, agreement, vote of stockholders or disinterested directors or otherwise. Notwithstanding the foregoing, the Company shall not be obligated to indemnify a director or officer in respect of a proceeding (or part thereof) instituted by such director or officer, unless such proceeding (or part thereof) has been authorized by the Board pursuant to the applicable procedure outlined in the indemnification agreements.

Section 174 of the DGCL provides, among other things, that a director, who willfully or negligently approves of an unlawful payment of dividends or an unlawful stock purchase or redemption, may be held jointly and severally liable for such actions. A director who was either absent when the unlawful actions were approved or dissented at the time may avoid liability by causing his or her dissent to such actions to be entered in the books containing the minutes of the meetings of the board of directors at the time such action occurred or immediately after such absent director receives notice of the unlawful acts.

The Company may purchase and maintain standard policies of insurance to protect the Company, its directors, officers, employees and agents for some liabilities

These provisions may discourage stockholders from bringing a lawsuit against our directors for breach of their fiduciary duty. These provisions also may have the effect of reducing the likelihood of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit the Company and our stockholders. Furthermore, a stockholder’s investment may be adversely affected to the extent we pay the costs of settlement and damage awards against officers and directors pursuant to these indemnification provisions.

The Company believes that these provisions, the insurance and the indemnity agreements are necessary to attract and retain talented and experienced officers and directors.

Item 15. | Recent Sales of Unregistered Securities.

Since three years before the date of the filing of this registration statement, the registrant has sold the following securities without registration under the Securities Act of 1933, as amended (the “Securities Act”):

| • |  | On February 13, 2025, Sandisk Corporation issued an additional 29,863,251 shares of its common stock to WDC, its then sole stockholder, such that WDC held an aggregate of 144,863,251 shares of Sandisk common stock. These additional shares were issued to WDC to facilitate WDC’s distribution of 80.1% of Sandisk common stock to WDC stockholders of record as of February 12, 2025, in connection with the spin-off.

Financial Statement schedules have been omitted because they are not applicable, not required or the required information is included in the combined Financial Statements or notes thereto (see the Index to Financial Statements included on page F-1 in this registration statement).

Item 17. | Undertakings.

(a) The undersigned registrant hereby undertakes:

| (1) | To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

| (i) | To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

| (ii) | To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of a prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;

| (iii) | To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

| (2) | That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

| (3) | To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

| (4) | That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

(b) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being

II-7

##### Table of Contents

registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

(c) The undersigned registrant hereby undertakes that:

| (1) | for purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act of 1933 shall be deemed to be part of this registration statement as of the time it was declared effective.

| (2) | for the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
