What Changed
Risk factors · Aug 20, 2024 → Aug 14, 202575 added · 113 removed between the two most recent 10-Ks. The risks a company starts — or stops — disclosing are often the story.
Newly disclosed
- Any imposition of or increase in tariffs may increase the cost of importing our products or the costs for materials or components used in our products, which would increase our costs unless we are able to implement actions to offset these costs, such as leveraging tariff exemptions where possible, optimizing our supply chain, sourcing from alternative suppliers, or passing the costs to our customers through tariff surcharges or increased prices.
- In addition, tariff actions by the United States and retaliatory actions by other countries have caused, and may in the future cause, significant disruption and volatility in the financial markets, which could adversely affect the availability, terms and cost of capital, including to refinance our existing debt, and which in turn could reduce our cash flows and harm our business. 10 Table of Contents Changes in tariffs and trade restrictions can be announced with little or no advance notice.
- These may include highly convincing phishing or social engineering attacks that use AI-generated deepfakes, the exploitation of vulnerabilities in electronic identity validation security programs via AI-replicated images or voices, or the inadvertent incorporation of malicious or hallucinated content generated by AI tools into our systems or those of our customers or partners.
- We are currently evaluating the impact of the OBBBA and related tax provisions on our operations and financial reporting, and future guidance provided by the U.S. 18 Table of Contents Department of the Treasury and Internal Revenue Service could change our conclusions regarding such impact.
- 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. 20 Table of Contents We and certain of our officers are and may continue to 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.
- Separately, the AI technologies that we employ for business purposes may be vulnerable to prompt-injection or other 12 Table of Contents adversarial attacks, which could result in unauthorized access to or leakage of sensitive information.
- Additionally, the impact of generative AI on the storage and data management markets and regulation thereof is still unfolding and could evolve unpredictably, and it is difficult to accurately forecast related demands.
- For the year ended June 27, 2025, the Cloud end market accounted for 88% of our total revenue and our top 10 customers accounted for 68% of our net revenue, with three customers each accounting for 10% or more of the Company’s net revenue. 15 Table of Contents If we fail to respond to changes in demand in the Cloud and hyperscale data center markets, our business could suffer.
- The $1.6 billion principal amount of our convertible notes will be convertible at the option of the holder beginning on August 15, 2028 and, prior to that date, may be convertible in any given calendar quarter depending on the trading price of our common stock during the prior calendar quarter.
- During the calendar quarter ended June 30, 2025, the sale price conditional conversion feature of the convertible notes was triggered and, as a result, the holders of the convertible notes have the right to convert the notes during the next succeeding calendar quarter.
- Although our Board of Directors authorized the adoption of a quarterly cash dividend program and a share repurchase program during the fourth quarter of fiscal year 2025, we are under no obligation to pay cash dividends to our stockholders in the future or to repurchase shares of our common stock at any particular price or at all.
- On February 21, 2025, we completed our planned spin-off of our Flash business unit from our remaining HDD business (which we refer to as the Separation), as a result of which Sandisk became an independent public company.
No longer disclosed
- For example, while Flash Ventures is operating, certain of our agreements with Kioxia preclude us 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 or acquisition by us.
- 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 three-month rolling basis are binding.
- The final determination to separate is subject to Board approval, the execution of definitive documentation, receipt of opinions or rulings as to the tax-free nature of the Separation and satisfaction of customary conditions, including the effectiveness of appropriate filings with the SEC, the completion of audited financial statements and the availability of financing.
- Furthermore, the Separation may leave us with higher leverage and may also cause us to violate provisions of contracts or breach covenants in our existing indebtedness if such contracts or indebtedness are not replaced, repaid or refinanced or waivers are not obtained prior to the Separation.
- 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.
- We and certain of our officers are and may continue to 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.
- 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.
- On October 30, 2023, we announced that our Board of Directors had completed its review of potential strategic alternatives and had unanimously approved pursuing a plan to separate the Flash business unit from our remaining HDD business (the “Separation”).
- 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.
- The Separation is intended to be structured in a tax-free manner and we continue to drive towards completing the work required to separate the businesses by the end of calendar year 2024.
- For example, each Flash Ventures entity operates for a defined period of time agreed upon between the joint venture partners.
- 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 IRC Section 174.
