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 Part I, Item 1A., Risk Factors of this Annual Report on Form 10-K.

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 3,200 pending patent applications worldwide. We continually seek additional 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 depend 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, 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 Part I, Item 1A., Risk Factors of this Annual Report on Form 10-K.

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. These processes require skill in process engineering and efficient space utilization in order to keep the operating costs of these specialized manufacturing environments under control. 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 offerings consist 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 provides 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 SDSS Venture. SDSS is 20% owned by Sandisk and 80% owned by JCET Management Co., Ltd. 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 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 the operations of Flash Ventures with Kioxia, 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. The Company’s 49.9% interest in the earnings of the Flash Ventures entities is recognized one quarter in arrears, reported in Other expense, net in the Consolidated Statements of Operations.

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 decides 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 be terminated earlier 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, 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 48% owned by the Company and 52% owned by Unis. The Unis Venture markets and sells the Company’s products in China.

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 in our Consolidated Financial Statements. Following 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 48% 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 Consolidated Statements of Operations.

For a discussion of associated risks, see Part I, Item 1A., Risk Factors of this Annual Report on Form 10-K.

Materials and Supplies

Our products consist of flash-based memory, controllers and firmware and other components. Following our separation from Western Digital, the Company has independently maintained strategic relationships with Flash Ventures and other key suppliers, and our supply relationships are now governed independently under the Company’s standalone procurement structure. We continue to source flash memory and components primarily through these partnerships, while independently managing our supplier portfolio to balance business continuity, cost efficiency, and risk mitigation. Substantially all of our flash memory wafers are currently obtained from Flash Ventures. From time to time, we also purchase flash memory wafers from other flash manufacturers. Controllers are primarily designed in-house and manufactured by third-party foundries or acquired from third-party suppliers. We believe the use of our assembly and test facilities, as well as contract manufacturers, provides flexibility and gives us access to increased production capacity.

We generally retain multiple suppliers for our component requirements, but for business or technology reasons we source some of our components from a limited number of sole or single source providers. For a discussion of associated risks, see Part I, Item 1A., Risk Factors of this Annual Report on Form 10-K.

Summary of Risk Factors

An investment in our common stock is subject to a number of risks, including market, financial, regulatory and operational risks related to our business, our separation from Western Digital Corporation (“WDC”) and our common stock. The following is a summary of certain key risk factors for investors in our securities. You should read this summary together with the more detailed description of risks and uncertainties discussed below.

RISKS RELATED TO OUR BUSINESS

Operational Risks

• Adverse global or regional conditions could harm our business.

• Disruption in our supply chain, other inability to source our supply requirements, or an increase in the costs of materials or components could negatively affect our business.

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 gro

Risk Management and Strategy

At Sandisk, our management team is charged with managing risk and bringing to our Board of Directors’ attention all material risk exposures to our company. Our enterprise risk management (“ERM”) process is designed to facilitate the identification, assessment, management, reporting and monitoring of material risks our company may face over the short-term and long-term and promote regular communication with our Board of Directors and its committees regarding these risks. Through our ERM process, we have determined that the compromise, damage or interruption of our technology infrastructure, information systems or products by cybersecurity incidents is a key risk to our company that may have a material negative impact on our business. To help mitigate the potential impact of cybersecurity incidents on our business and protect against cybersecurity threats, we have established organizational structures, procedural measures and response plans that define roles and responsibilities related to cybersecurity risk management.

Sandisk’s Information Security organization addresses cybersecurity risks with a broad spectrum of technologies, controls, and processes that focus on mitigating these risks. Our cybersecurity strategy is designed to be dynamic and adaptive to combat the rapidly-evolving cybersecurity threat landscape and is influenced by commonly leveraged frameworks such as the NIST-CSF (National Institute of Standard and Technologies – Cyber Security Framework). Our program includes, but is not limited to, endpoint protection and response systems, network security protocols, electronic communications protections, vulnerability management programs, least-privilege access controls, third-party risk management procedures, workforce education and training exercises, and compliance programs.

Our dedicated 24x7 Security Operations Center incorporates specialized systems and processes for handling security incidents into its regular work and operates a robust, modern security infrastructure with appropriate security sensors and event monitoring capabilities. Upon detection of a cybersecurity incident, the Security Operations Center determines the severity of the incident in accordance with a pre-established incident severity matrix, initiates the appropriate notification and escalation protocols and begins triage. Predefined severity tiers serve as a guide to match our response to each incident’s determined severity or risk level.

Additionally, we have established a Cyber Incident Response Plan that follows the structure of the Incident Handling Guide published by the U.S. National Institute of Standards and Technology (SP 800-61r2) and that serves as an operational guide for handling cybersecurity incidents at Sandisk. Our Cyber Incident Response Plan provides procedural and strategic guidance that is designed to be flexible enough to apply to a variety of different incidents, but also specific enough to provide guidelines for incident prevention, detection, analysis, escalation and notification, and containment, eradication and recovery.

As part of our ongoing information security program, the Company utilizes periodic independent third-party experts to conduct assessments of our program’s effectiveness. These experts are also leveraged to design and orchestrate tabletop exercises where multiple business functions and leadership levels navigate incident scenarios based on industry trends and relevant threats, to help determine our level of preparedness for various cybersecurity incidents.

As part of our business operations, the Company engages with a number of third parties, including but not limited to, online software service providers, vendors, consultants, and partners. These third parties are analyzed based on business criticality and impact and must be cleared through a formal cybersecurity risk assessment process before being allowed to integrate with Sandisk’s information systems, access confidential data, or provide electronic services to members of our workforce.

The Company has in the past experienced cybersecurity incidents of varying degrees involving our technology infrastructure and information systems. While these incidents have at times resulted in some disruptions to our business operations, as of the date of this Annual Report on Form 10-K, we do not believe that known risks from cybersecurity threats, including as a result of any previous cybersecurity incident, have materially affected or are reasonably likely to materially affect us, including our business strategy, results of operations or financial condition. However, we can give no assurance that we have detected or protected against all such cybersecurity incidents or threats or that we will not experience such an incident in the future. Further details about the cybersecurity risks we face are described under “The compromise, damage or interruption of our technology infrastructure, information systems or products by cybersecurity incidents, data security breaches, other security problems, design defects, information system failures or other events could have a material negative impact on our business” in Part I, Item 1A., Risk Factors of this Annual Report on Form 10-K.

Governance

The Company has implemented a governance framework related to cybersecurity that includes operational risk-mitigation practices and Board-level cybersecurity risk oversight.

Our management team is charged with managing cybersecurity risk and identifying material cybersecurity risk exposures to our company and carries out this function primarily through our Information Security organization, which is led by our Chief Information Security Officer (“CISO”) who has a CISO executive certification from the Heinz College at Carnegie Mellon University, a bachelor’s degree in Electrical Engineering, over a decade of information security leadership, and over twenty years of consolidated IT leadership experience. Additionally, our Cyber Incident Response Plan discussed above calls for the establishment of a management Impact Assessment Committee, which consists of key leadership representatives from the organization and is convened on an ad hoc basis to assess the detailed business impact of a cybersecurity incident. The Impact Assessment Committee is led by our Chief Information Security Officer and includes key representatives from the Company’s functional groups, including human resources, ethics and compliance, labor, privacy, internal audit, finance, communications, legal, risk and accounting. The Impact Assessment Committee receives updates and communications from the Security Operations Center on a fixed cadence determined by incident severity and follows our pre-established escalation framework to communicate with and include executive leadership, outside counsel and the Board of Directors, as appropriate. The Impact Assessment Committee works with the Company’s internal and external legal counsel to determine and facilitate appropriate communications with the Board of Directors.

Our Board of Directors is responsible for overseeing the cybersecurity risk management process and exercises this risk oversight through both our full Board of Directors and its Audit Committee. Our Board of Directors has delegated to the Audit Committee the responsibility to oversee risks related to cybersecurity threats, and our Audit Committee Charter requires the Audit Committee to review and discuss with management the Company’s policies with respect to risk assessment and enterprise risk management and to review the risk exposure of the Company related to the Committee’s areas of responsibility, including with respect to cybersecurity. In carrying out this role, the Audit Committee meets with our Chief Information Security Officer regularly and receives at least quarterly reports on cybersecurity matters.

Additionally, at least annually, our Chief Audit Executive, who manages the day-to-day activities of our ERM program, reports to our Board of Directors on enterprise risk assessment under our ERM program, providing updates on key risks, status of mitigation efforts and residual risk trends, including an analysis of cybersecurity risks. Also at least annually, our Chief Information Security Officer reports to the full Board of Directors on cybersecurity matters related to or impacting our company and our business.

Our principal executive offices are currently located at 951 Sandisk Drive, Milpitas, California 95035. Our principal manufacturing, research and development (“R&D”), marketing and administrative facilities as of the date of this information statement were as follows:

We also lease office space in various other locations throughout the world primarily for R&D, sales, operations, manufacturing, administration and technical support. We believe our present facilities are adequate for our current needs, although we update our facilities from time to time to meet anticipated future technological and market requirements.

Substantially all of our flash-based memory wafers are manufactured by the Flash Ventures in purpose-built, wafer fabrication facilities, that they lease, located in Yokkaichi and Kitakami, Japan.

There are no material legal proceedings, other than ordinary routine litigation incidental to the company, to which we or any of our subsidiaries is a party or of which any of our or our subsidiaries’ property is subject.

Overview

The Separation

On October 30, 2023, Western Digital Corporation (“WDC”) announced that its board of directors (the “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. Prior to February 21, 2025, we were wholly owned by WDC.

On February 21, 2025, WDC executed the spin-off of the Company through WDC’s pro rata distribution of 116,035,464 or 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 28,827,787 or 19.9% of the outstanding shares of the Company’s common stock, which WDC was expected to retain for a period of up to twelve months following the distribution. Following the distribution, the Company became an independent publicly listed company, and on February 24, 2025, the Company began trading as an independent publicly traded company under the stock symbol “SNDK” on Nasdaq.

On June 6, 2025, WDC disposed of 21,314,768 or 14.6% of our common stock through an exchange of our common stock for WDC debt held by WDC creditors.

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 artificial intelligence (“AI”) workloads in datacenters, edge devices, and consumers. Our technologies enable everyone from students, gamers and home offices to the largest enterprises and public clouds to produce, analyze, and store data. Our solutions include a broad range of solid-state drives (“SSDs”), 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.”

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 presence around the world. Cloud is comprised primarily of products for datacenters, cloud service providers, and private cloud 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 years 2025, 2024, and 2023, which ended on June 27, 2025, June 28, 2024, and June 30, 2023 are each comprised of 52 weeks, with each fiscal quarter consisting of 13 weeks. Fiscal year 2026 will be comprised of 52 weeks and end on July 3, 2026.

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 were allocated to us on a relative square footage basis. The property is being leased back to us 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 that provide the ability to extend through December 2057. The associated operating lease liability and right-of-use asset for this facility have been included in the Consolidated Balance Sheets as of June 27, 2025 and June 28, 2024.

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

As discussed in Part II, Item 8., Note 10, Related Parties and Related Commitments and Contingencies of the Notes to the Consolidated Financial Statements included in this Annual Report on Form 10-K, on September 28, 2024, prior to the separation, WDC’s wholly-owned subsidiary, SanDisk China Limited (“SanDisk China”) completed the sale of 80% of its equity interest in SDSS (the “Transaction”) 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 “SDSS Venture”). The Transaction resulted in a pre-tax gain of $34 million.

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. 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. As a result of the Transaction, we expect to incur a modest reduction in annual operating expenses and a reduction in annual capital expenditure related to the assembly and testing of flash-based products. We also anticipate that the transition to a contract manufacturing model through the SDSS Venture will result in a small increase in our annual cost of revenue for flash-based products.

Goodwill Impairment

As discussed in Part II, Item 8., Note 5, Supplemental Financial Statement Data of the Notes to the Consolidated Financial Statements included in this Annual Report on Form 10-K, subsequent to the separation, we conducted a quantitative analysis of potential goodwill and long-lived assets impairments, in accordance with Accounting Standards Codification (“ASC”) No. 350, Intangibles - Goodwill and Other. This analysis indicated that the estimated carrying value of our reporting unit exceeded its fair value. Consequently, we recorded a goodwill impairment charge of $1.8 billion during the third quarter of the fiscal year ended June 27, 2025.

Our policy is to perform an annual impairment test on the first day of the fourth fiscal quarter. For the year ended June 27, 2025, we performed a qualitative analysis which did not indicate that goodwill was more-likely-than-not impaired. As a result, no additional quantitative analysis was required and no additional impairment charge was recorded during the fiscal year ended June 27, 2025.

Financing Activities

Prior to the separation, 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) Western Digital Corporation is included in Part II, Item 8., Note 10, Related Parties and Related Commitments and Contingencies of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K.

As discussed in Part II, Item 8., Note 8, Debt of the Notes to the Consolidated Financial Statements included in this Annual Report on Form 10-K, on February 21, 2025, we entered into a loan agreement comprised of a seven-year Term Loan B facility in an aggregate principal amount of $2.0 billion (the “Term Loan Facility”) and a five-year revolving credit facility (the “Revolving Credit Facility”) in an aggregate principal amount of $1.5 billion with $150 million available for letters of credit.

On February 21, 2025, we borrowed $2.0 billion under the Term Loan Facility. We used a portion of the proceeds of the borrowing to make a net distribution payment of approximately $1.5 billion to WDC, with the remainder to be used for general corporate purposes. The proceeds of the Revolving Credit Facility may be used for working capital and general corporate purposes.

As of June 27, 2025, we have drawn no amounts under the Revolving Credit Facility.

Operational Update

In 2025, we generally saw an improvement in the supply and demand dynamics, leading to improved revenues and gross margin in fiscal 2025 compared to 2024. As part of our actions to align supply with market demand in the later half of fiscal 2025, we incurred charges for unabsorbed manufacturing overhead costs due to reduced utilization of our manufacturing capacity totaling $75 million, and we anticipate incurring some underutilization charges as we moderate production levels to align with demand for our products in the first quarter of 2026.

Additionally, in 2025, the U.S. announced changes to U.S. trade policy, including increased tariffs on imported goods. Currently, the majority of our products sold in the U.S. are exempt from tariffs, but additional tariff increases, or the loss of applicable exemptions would increase the cost of goods sold for our products sold in the U.S., which could negatively impact our margins and financial performance. Increases in the price of our products in response to increased costs may adversely impact demand for those products in the U.S., which could also negatively impact our performance and financial results. 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, and the impact of these factors on our business are uncertain and may contribute to increased costs and reduced demand for our products, each of which could harm our financial performance.

With regard to technological advances, we anticipate that digital transformation, including the AI data-cycle, will drive improved market conditions in the long term for our data storage 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.

Basis of Presentation

On February 21, 2025, we became a standalone publicly traded company, and our financial statements are now presented on a consolidated basis. Prior to the separation, our historical financial statements were derived from WDC’s consolidated financial statements and accounting records and prepared as if we existed on a standalone basis. The financial statements for all periods presented, including our historical results prior to February 21, 2025, are now referred to as “Consolidated Financial Statements” and have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”).

The following discussion reflects our financial condition and results of operations as set forth in the Consolidated Financial Statements included in this Annual Report on Form 10-K.

The Consolidated Statements of Operations include all revenues and costs directly attributable to us, including costs for facilities, functions, and services used by us. Prior to the separation, our business had historically functioned together with the other businesses controlled by WDC. Accordingly, we relied on WDC’s corporate overhead and other support functions. Therefore, certain corporate overhead and shared costs were allocated to us including (i) certain general and administrative expenses related to WDC’s 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 were 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. While management considers that such allocations were made on a reasonable basis consistent with benefits received, the Consolidated Financial Statements included in this Annual Report on Form 10-K may not be indicative of our future performance, do not necessarily include the actual expenses that would have been incurred by us and may not reflect our results of operations, financial position, and cash flows had we been a separate, standalone company during the periods presented. For additional information, see Part II, Item 8., Note 1, Organization, Basis of Presentation and Summary of Significant Accounting Policies of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K.

Results of Operations

Overview

The following table sets forth, for the periods presented, selected summary information from our Consolidated Statements of Operations by dollars and percentage of net revenue(1):

(1) Percentage may not total due to rounding.

The following table sets forth, for the periods presented, summary information regarding our disaggregated revenue:

Our 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, we provide our 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 capitalize on the strength of our product brand recognition and vast points of presence around the world.

Net Revenue

Net revenue increased 10%, or $692 million, in 2025 compared to 2024, primarily due to a 6% increase in exabytes sold due to stronger demand in our Cloud end market and a 4% increase in average selling prices (“ASP”) per gigabyte due to enhanced pricing as the supply-demand balance improved.

Cloud revenue increased 195%, or $635 million, in 2025 compared to 2024, primarily due to a 153% increase in exabytes sold due to increased enterprise SSD shipments to data center customers and a 17% increase in ASP per gigabyte due to improved pricing.

Client revenue increased 1%, or $58 million, in 2025 compared to 2024, primarily due to an 8% increase in ASP per gigabyte, partially offset by a 7% decrease in exabytes sold.

Consumer revenue decreased $1 million in 2025 compared to 2024, primarily due to a 6% increase in exabytes sold, offset by a 7% decrease in ASP per gigabyte due to pricing pressure.

The changes in net revenue by geography in 2025 compared to 2024 primarily reflected higher revenue in the Americas region from Cloud customers.

Consistent with standard industry practice, we offer sales incentives and marketing programs that provide customers with price protection and other incentives or reimbursements that are recorded as reductions of gross revenue. For 2025, 2024 and 2023, these programs represented 19%, 19%, and 21%, 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

Gross profit increased $1,140 million in 2025 compared to 2024, primarily due to improved pricing, a favorable product mix, a decrease in manufacturing underutilization charges incurred in 2025 compared to the comparable prior year period, and a $54 million write-down of Flash inventory in 2024 as a result of decreases in market pricing, for which a similar charge was not incurred in 2025, partially offset by $36 million of insurance recoveries received during 2024 for losses incurred due to a contamination incident in 2022. In 2024, we recognized a $252 million charge due to reduced manufacturing capacity utilization, compared to an underutilization charge of $75 million incurred in 2025.

Gross profit margin increased 14% in 2025 compared to 2024, with approximately 10% driven by higher revenue due to improved pricing, higher demand for our offerings, and favorable product mix and the remaining 4% due to the decrease in manufacturing underutilization charges incurred in 2025 and a write-down of Flash inventory in 2024 for which a similar charge was not incurred in the current period.

Operating Expenses

Research and development (“R&D”) expenses increased $71 million in 2025 compared to 2024, primarily due to a $32 million increase in compensation and benefits mainly due to higher variable compensation which includes short-term incentives, an $18 million increase in spending for R&D projects, a $15 million increase in material purchases, and a $5 million increase in legal and outside service fees.

Selling, general and administrative expenses increased $118 million in 2025 compared to 2024, primarily due to an $84 million increase in compensation and benefits due to higher variable compensation which includes short-term incentives, a $24 million increase in materials, a $16 million increase in legal service fees, and a $14 million increase in sales and marketing expenses, partially offset by a $20 million decrease in strategic review costs incurred in 2024 for which there are no comparable costs in the current year.

Employee termination and other charges decreased $61 million in 2025 compared to 2024, primarily due to a $60 million gain on the sale-leaseback of a facility in the prior period, for which there is no comparable transaction in 2025. For additional information regarding employee termination and other charges, see Part II, Item 8., Note 15, Employee Termination and Other Charges of the Notes to Consolidated Financial Statements included in this Annual Report.

Goodwill impairment

Goodwill impairment increased $1.8 billion in 2025 compared to 2024 due to an impairment charge resulting from the difference between the carrying value of our reporting unit and its fair value.

Business separation costs

Business separation costs increased $3 million in 2025 compared to 2024, primarily due to the completion of the separation from WDC.

Gain on business divestiture

Gain on business divestiture increased $34 million in 2025 compared to 2024 due to the pre-tax gain on the sale of SDSS.

Interest and Other Expense, net

Interest and other expense, net increased $67 million in 2025 compared to 2024, primarily due to a $56 million increase in interest expense from our Loan Agreement, a $37 million increase in losses on our equity method investments, and a $24 million increase in foreign exchange losses, partially offset by a $28 million decrease in interest expense on borrowings due to WDC, a $15 million increase in interest income due to an increase in available cash, and a $7 million increase in interest income arising from the accretion of the present value discount on the outstanding SDSS sale consideration receivable.

Income Tax Expense

H.R.1, more widely known as the Big Beautiful Bill Act, was recently signed into law on July 4, 2025. It reversed the requirement for capitalization of U.S. research and development expenditures that came into law under the Tax Cuts and Jobs Act of 2017, but the mandatory requirement of capitalization of foreign research and development expenditures remains. The tax rates for income earned by our foreign subsidiaries will also be changed under H.R. 1. Depending on our operating results, these changes can materially impact our effective tax rate and reduce our operating cash flows. As H.R.1 was enacted after our fiscal year 2025, its impact on the tax provision will be reflected in fiscal year 2026.

On August 16, 2022, the Inflation Reduction Act of 2022 was signed into law, 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. We do not expect to be subject to the CAMT of 15% for 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 Pillar Two, some of which are effective for us in 2025. For 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 2026, there may be material increases in our future tax obligations in certain jurisdictions.

The following table presents our Income tax expense and the effective tax rate:

The relative mix of earnings and losses by jurisdiction, the goodwill impairment, the foreign income inclusion, credits, and tax holidays in Malaysia that will expire at various dates during years 2028 through 2031 resulted in decreases to the effective tax rate below the U.S. statutory rate for the years ended June 27, 2025.

For additional information regarding income tax expense, see Part II, Item 8., Note 14, Income Tax Expense of the Notes to the Consolidated Financial Statements included in this Annual Report on Form 10-K.

Financial condition, liquidity and capital resources

The following table summarizes our Consolidated Statements of Cash Flows:

In alignment with market conditions, we have maintained a conservative capital expenditure strategy for 2025 and 2024. For fiscal year 2026, we anticipate increased capital investments as we transition to newer nodes to meet the demand and technology needs of our product portfolio.

We believe our cash and cash equivalents will be sufficient to meet our working capital needs for at least the next twelve months and for the foreseeable future thereafter. We believe we can also access the various capital markets to further supplement our liquidity position if necessary. Our ability to sustain our working capital position is subject to a number of risks that we discuss in Part I, Item 1A., Risk Factors included in this Annual Report on Form 10-K.

A total of $692 million and $321 million of our cash and cash equivalents were held outside of the U.S. as of June 27, 2025 and June 28, 2024 respectively. There are no material tax consequences that were not previously accrued for the repatriation of this cash. Our cash equivalents are primarily invested in money market funds that invest in U.S. Treasury securities and U.S. Government agency securities.

Operating Activities

Net cash provided by (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 $380 million for 2025, compared to $86 million net cash provided for 2024, 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 (in days):

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 payable 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 payment term modifications through negotiations with our vendors or by granting to or receiving from our vendors payment term accommodations.

In 2025, DSO increased 3 days when compared to the prior year, reflecting lower accounts receivable factoring and the timing of shipments and customer collections. DIO decreased 23 days over the prior year, primarily reflecting greater consumption of inventory. DPO decreased 4 days over the prior year, primarily due to routine variations in the timing of purchases and payments.

Investing Activities

Net cash provided by investing activities in 2025 primarily consisted of $401 million in net proceeds from our sale of a majority interest in one of our subsidiaries and $358 million in net proceeds from activity related to Flash Ventures, partially offset by $204 million in capital expenditures. Net cash provided by investing activities in 2024 primarily consisted of $239 million in net proceeds from activity related to Flash Ventures and $137 million of proceeds from the sale-leaseback of our Milpitas, California facility, partially offset by $166 million in capital expenditures.

Financing Activities

Net cash provided by financing activities in 2025 primarily consisted of $1,970 million in proceeds from borrowings from the Term Loan Facility, $550 million in proceeds from borrowings on notes due to WDC, and $101 million in proceeds from principal repayments on notes due from WDC, partially offset by $1,887 million transferred to WDC, $100 million in repayment on the Term Loan Facility, and $76 million in net repayments on notes due to WDC. Net cash provided by financing activities in 2024 primarily consisted of $394 million in net transfers from WDC, partially offset by $170 million in origination of notes due from WDC and $102 million in net repayments on notes due to WDC.

A discussion of our cash flows for 2024, including a comparison of such cash flows to 2023, is included in Item 2., Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Form 10.

Off-Balance Sheet Arrangements

Other than the Flash Ventures and SDSS-related commitments 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 obligations 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 Consolidated Financial Statements. Additionally, with the exception of Flash Ventures, the SDSS Venture and the Unis 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 Part II, Item 8., Note 10, Related Parties and Related Commitments and Contingencies of the Notes to the Consolidated Financial Statements included in this Annual Report on Form 10-K.

Short-and-Long-term Liquidity

Material Cash Requirements

The following is a summary of our known material cash requirements, including those for capital expenditures, as of June 27, 2025. In addition, see the discussions further below related to unrecognized tax benefits, foreign exchange contracts and indemnifications.

(1) Principal portion of debt, excluding issuance costs.

(2) 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 R&D and building depreciation. Funding commitments assume no additional operating lease guarantees. Additional operating lease guarantees can reduce funding commitments.

Debt

In connection with the separation, on February 21, 2025, we entered into a loan agreement (the “Loan Agreement”) comprised of a $1.5 billion revolving credit facility, on which no amounts have been drawn, and a $2.0 billion term loan facility due in 2032. The Company used a portion of the proceeds received from the term loan facility, as well as cash on hand, to make a net distribution payment of $1.5 billion to WDC in exchange for assets, liabilities and certain legal entities of WDC associated with the Company.

As of June 27, 2025, we were in compliance with the Loan Agreement financial covenant that requires us to maintain a maximum Leverage Ratio. Additional information regarding our indebtedness, including information about availability under our revolving credit facility and the principal repayment terms, interest rates, covenants, collateral and other key terms of our outstanding indebtedness, is included in Part II, Item 8., Note 8, Debt of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K.

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 of 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 June 27, 2025, and as of June 28, 2024, we were in compliance with all covenants under these Japanese lease facilities. See Part II, Item 8., Note 10, Related Parties and Related Commitments and Contingencies of the Notes to the Consolidated Financial Statements included in this Annual Report on Form 10-K for information regarding Flash Ventures.

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 June 27, 2025, our liability for unrecognized tax benefits (excluding accrued interest and penalties) was approximately $140 million. Accrued interest and penalties included in the Company’s liability related to unrecognized tax benefits as of June 27, 2025 and June 28, 2024 was $11 million and $9 million, respectively. Of these amounts, approximately $138 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. See Part II, Item 7A., Quantitative and Qualitative Disclosures About Market Risk included in this Annual Report on Form 10-K for additional information.

Indemnifications

Concurrent with the separation, we and WDC entered into a Tax Matters Agreement under which we and WDC agreed to indemnify each other for certain tax positions. As a result of this agreement, we recorded a tax indemnification liability of $112 million on February 21, 2025, which was recognized as an adjustment to the Net investment from Western Digital Corporation. This liability was subsequently reduced by approximately $2 million, reflecting the outstanding balance as of June 27, 2025. The remaining tax indemnification liability of $110 million is classified as Other liabilities in the Consolidated Balance Sheets as of June 27, 2025.

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.

Recent Accounting Pronouncements

Recently Issued Accounting Pronouncements Not Yet Adopted

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” This 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 July 3, 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. This ASU 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 ASU 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. The Company expects to provide any required disclosures for annual reporting periods included in the Company’s financial statements for the year ending June 30, 2028.

Critical Accounting Estimates

We have prepared the accompanying Consolidated Financial Statements in accordance with accounting principles generally accepted in the United States. The preparation of the financial statements requires the use of judgments and estimates that affect the reported amounts of revenues, expenses, assets, and liabilities. 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 Consolidated Financial Statements may be material. Our accounting policies are fully described in Part II, Item 8., Note 1, Organization, Basis of Presentation and Summary of Significant Accounting Policies of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K.

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. We record estimates of variable consideration related to these items as a reduction of 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. We constrain variable consideration until the likelihood of a significant revenue reversal is not probable and believe 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, our methodology for estimating variable consideration is based on the amount of consideration expected to be earned based on the OEMs’ volume of purchases from 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 the 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 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. Adjustments to the reserve in 2025 were immaterial.

Goodwill

Goodwill attributed to us 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 at least 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. 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 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 and assumptions used to determine the fair value as well as the actual carrying value may change based on future changes in our results of operations, macroeconomic conditions, or other factors. Changes in these estimates and assumptions could materially affect our 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 our financial condition and results of operations.

Subsequent to the completion of the separation in February 2025, we identified potential impairment indicators related to macroeconomic indicators, industry developments, the trading price of our common stock and resulting market capitalization that warranted a quantitative impairment analysis of long-lived assets and goodwill.

Subsequently, we performed a quantitative test, which indicated that the carrying value of our reporting unit exceeded its estimated fair value, resulting in the recognition of a $1.8 billion impairment charge during the third quarter of the year ended June 27, 2025 which was recorded in the accompanying Consolidated Statements of Operations.

We performed a qualitative impairment test on the first day of the fourth fiscal quarter, which did not indicate that goodwill was more-likely-than-not impaired. As a result, no additional quantitative analysis was required and no additional impairment charge was recorded during the fiscal year ended June 27, 2025, other than as stated above.

The tests for goodwill and long-lived asset impairment are further explained in Part II, Item 8., Note 5, Supplemental Financial Statement Data of the Notes to the Consolidated Financial Statements. Determining the fair value used in our impairment calculations involves using significant estimates and assumptions, including revenue forecasts, terminal growth rate, tax rate, and a weighted average cost of capital adjusted for company-specific risk. These estimates and assumptions are based on the most current information available to the Company, and there is no assurance that these estimates and assumptions will accurately predict future outcomes. If our assumptions are not realized, or if any of these assumptions change due to changes in economic conditions, our results of operations, or other factors, it is possible that an additional impairment charge may be recorded.

Foreign Currency Risk

Although the majority of our transactions are in U.S. dollars, some transactions are based in various foreign currencies. We have historically purchased 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 reduce the impact of foreign currency fluctuations on our results of operations. Substantially all of the contract maturity dates do not exceed twelve months. We do not purchase foreign exchange contracts for speculative or trading purposes.

We have performed sensitivity analyses as of June 27, 2025, 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 June 27, 2025. 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 $85 million at June 27, 2025.

During 2025, 2024 and 2023, total net realized and unrealized transaction and foreign exchange contract currency losses were $29 million, $4 million, and $5 million, respectively, to our Consolidated Financial Statements.

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. Additionally, the overall effectiveness of our historical hedging strategy is dependent on business, market and global economic conditions. We have revised, and may continue to alter, our hedging program and may choose to discontinue our hedging activities at any time.

Interest Rate Risk

We held variable rate debt. As of June 27, 2025, our variable rate debt outstanding consisted of our Term Loan Facility, which is based on various index rates as discussed further in Part II, Item 8., Note 8, Debt of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K. As of June 27, 2025, the outstanding balance on our variable rate debt was approximately $1.9 billion and a one percent increase in the variable rate of interest would increase our annual interest expense by $19 million.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors

Sandisk Corporation:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Sandisk Corporation and subsidiaries (the Company) as of June 27, 2025 and June 28, 2024, the related consolidated statements of operations, comprehensive income (loss), shareholders’ equity, and cash flows for each of the fiscal years in the three-year period ended June 27, 2025, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of June 27, 2025 and June 28, 2024, and the results of its operations and its cash flows for each of the fiscal years in the three-year period ended June 27, 2025, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audit. 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 Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audit included performing procedures to assess the risks of material misstatement of the consolidated 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 consolidated financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audit provides 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 consolidated 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 consolidated 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 consolidated 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 consolidated financial statements, the Company provides resellers with price protection for inventories held by resellers at the time of published list price reductions and other sales incentive programs. The Company records estimated variable consideration related to these items as a reduction to revenue at the time of revenue recognition. The Company uses judgment in its assessment of variable consideration in contracts to be included in the transaction price. For sales to resellers, the Company’s methodology for estimating variable consideration is based on several factors, including historical pricing information, current pricing trends, and channel inventory levels.

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 Company’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. To assess the reasonableness of the estimated variable consideration for sales to resellers, we developed an independent expectation of the variable consideration for sales to resellers based on historically recorded payments and issued credits and then compared our expectation to the estimated variable consideration recorded.

We have served as the Company’s auditor since 2023.
