Q1 2026 Financial Highlights

Additional details can be found within the Company’s earnings presentation, which is accessible online at investor.sandisk.com.

(1) Non-GAAP gross margin guidance excludes stock-based compensation expense and expense for short-term incentives granted in connection with the separation, totaling approximately $4 million to $6 million. The Company’s Non-GAAP operating expenses guidance excludes stock-based compensation expense and expense for short-term incentives granted in connection with the separation, totaling approximately $47 million to $63 million . The Company’s Non-GAAP interest and other expenses, net guidance excludes the accretion of the present value discount on consideration receivable from the sale of an interest in a subsidiary, totaling approximately $2 million. In the aggregate, Non-GAAP diluted net income per share guidance excludes these items totaling $49 million to $67 million. The timing and amount of these charges excluded from Non-GAAP gross margin, Non-GAAP operating expenses, Non-GAAP interest and other expenses, net, and Non-GAAP diluted net income per share cannot be further allocated or quantified with certainty. Additionally, the timing and amount of additional charges the Company excludes from its Non-GAAP diluted net income per share are dependent on the timing and determination of certain actions and cannot be reasonably predicted. Accordingly, full reconciliations of Non-GAAP gross margin, Non-GAAP operating expenses, Non-GAAP interest and other expenses, net, and Non-GAAP diluted net income per share to the most directly comparable GAAP financial measures (gross margin, operating expenses, and diluted net income per share, respectively) are not available without unreasonable effort.

(2) Non-GAAP tax expense is determined based on a Non-GAAP pre-tax income or loss. Our estimated Non-GAAP tax expense may differ from our GAAP tax expense (i) due to differences in the tax treatment of items excluded from our Non-GAAP net income or loss; (ii) due to the fact that our GAAP income tax expense or benefit recorded in any interim period is based on an estimated forecasted GAAP tax expense for the full year, excluding loss jurisdictions; and (iii) because our GAAP taxes recorded in any interim period are dependent on the timing and determination of certain GAAP operating expenses.

To supplement the condensed consolidated financial statements presented in accordance with GAAP, the table above sets forth Non-GAAP gross profit; Non-GAAP operating expenses; Non-GAAP operating income; Non-GAAP interest and other expense, net; Non-GAAP income tax expense; Non-GAAP net income; Non-GAAP diluted net income per share; Non-GAAP diluted weighted average shares outstanding; Free cash flow; and Adjusted free cash flow (collectively, the “Non-GAAP measures”). These Non-GAAP measures are not in accordance with, or alternatives for measures prepared in accordance with GAAP and may be different from similarly titled Non-GAAP measures used by other companies. The Company believes the presentation of these Non-GAAP measures, when shown in conjunction with the corresponding GAAP measures, provides useful information to investors for measuring the Company’s earnings performance and comparing it against prior periods. Specifically, the Company believes these Non-GAAP measures provide useful information to both management and investors as they exclude certain expenses, gains, and losses that the Company believes are not indicative of its core operating results or because they are consistent with the financial models and estimates published by many analysts who follow the Company and its peers. As discussed further below, these Non-GAAP measures exclude, as applicable, stock-based compensation expense, business separation costs, employee termination and other, loss on business divestiture, other adjustments, and income tax adjustments. The Company believes these measures, along with the related reconciliations to the most directly comparable GAAP measures, provide additional detail and comparability for assessing the Company’s results. These Non-GAAP measures are some of the primary indicators management uses for assessing the Company’s performance and planning and forecasting future periods. These measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for, or superior to, GAAP results.

As described above, the Company excludes the following items from its Non-GAAP measures:

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

Business separation costs. 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, the Company was wholly-owned by WDC. As a result of the plan, the Company incurred separation and transition costs through the completion of the separation of the companies. The separation and transition costs are recorded within Business separation costs in the Condensed Consolidated Statements of Operations. The Company believes these charges do not reflect the Company’s operating results and that they are not indicative of the underlying results of its business.

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

Loss on business divestiture. In connection with the Company’s strategic decision to outsource the manufacturing of certain components and assemblies, on September 28, 2024, the Company completed the sale of 80% of its equity interest in one of its manufacturing subsidiaries. On September 25, 2025, the Company entered into an Amended and Restated Equity Purchase Agreement that included a $10 million provision for working capital support. The Company recognized the adjustment as a Loss on business divestiture for the three months ended October 3, 2025. The overall transaction resulted in a discrete gain, which the Company believes is not indicative of the underlying performance of its ongoing business operations.

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

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 the re-measurement of certain unrecognized tax benefits primarily related to tax positions taken in prior quarters, including interest. These adjustments are excluded because the Company believes that they are not indicative of the underlying performance of its ongoing business.

Additionally, Free cash flow is defined as cash flows provided by (used in) operating activities less purchases of property, plant and equipment, net, and Adjusted free cash flow is defined as free cash flow plus the activity related to Flash Ventures, net. The Company considers Free cash flow and Adjusted free cash flow generated in any period to be useful indicators of cash that is available for strategic opportunities, including, among others, investing in the Company’s business, making strategic acquisitions, repaying debt and strengthening the balance sheet.
