free cash flow financial
""Free cash flow is defined as cash flows provided by operating activities less purchases of property""
Free cash flow is the amount of money a company has left over after paying all its expenses and investing in its business, like buying equipment or updating facilities. It shows how much cash is available to reward shareholders, pay down debt, or save for future growth. This helps investors understand if a company is financially healthy and able to grow.
non-GAAP gross margin financial
""Non-GAAP gross margin guidance excludes stock-based compensation expense, totaling approximately $10 million""
Non-GAAP gross margin is a measure of a company's profitability that shows how much money it makes from sales after subtracting the direct costs of producing its products or services, but without applying certain accounting adjustments required by standard rules. It helps investors understand the company's core earning ability by excluding items like one-time expenses or accounting changes. This metric provides a clearer picture of ongoing business performance beyond official financial reports.
business realignment (charges) credits financial
""Business realignment (charges) credits. From time to time, in order to realign the company’s operations""
capped call transactions financial
""benefit expected to be provided by existing capped call transactions entered into in connection with the 2028 convertible notes""
Capped call transactions are agreements where investors buy options that give them the chance to benefit if a stock's price goes up, but with a limit on how much they can gain. This helps protect them from paying too much if the stock's price rises a lot, similar to having a maximum limit on a reward. They matter because they help investors manage risk while still allowing some upside potential.
convertible notes transactions financial
""In connection with these transactions, the company recognized costs primarily related to a discount given to the counterparty""
retained interest in Sandisk financial

Discussion Regarding the Use of Non-GAAP Financial Measures
To supplement the condensed consolidated financial statements presented in accordance with U.S. generally accepted accounting principles (“GAAP”), this press release sets forth certain financial measures that are not calculated in accordance with GAAP (“non-GAAP measures”). These non-GAAP measures, which are detailed in the reconciliation tables above, are not 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; charges related to a litigation matter; business realignment (charges) credits; (gain) loss on retained interest in Sandisk; costs in connection with debt and equity transactions; income tax adjustments; and other adjustments. The company believes these measures, along with the related reconciliations to the 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 its 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.

Litigation matter. In previous periods, the company had recognized expenses related to a judgment in a patent litigation matter, which consisted of an award of damages, interest, estimated plaintiff legal costs and other charges. A portion of these expenses were reversed upon a subsequent settlement with the plaintiff. The company believes these charges and subsequent reversals do not reflect the company’s operating results and that they are not indicative of the underlying performance of its business.

Business realignment (charges) credits. From time to time, in order to realign the company’s operations with anticipated business needs or to achieve cost synergies from the integration of acquisitions, the company may incur charges in connection with actions to terminate employees, impair assets or otherwise restructure its operations and may recognize credits related to charges previously incurred. These (charges) credits are inconsistent in amount and frequency, and the company believes they are not indicative of the underlying performance of its business.

(Gain) loss on retained interest in Sandisk. The company retained an ownership interest in Sandisk at the time of the Separation and has recognized gains on the mark-to-market adjustment of such interest. The company believes these adjustments do not reflect the company’s operating results and are not indicative of the underlying performance of its business.

Costs in connection with debt and equity transactions. In connection with the company’s actions to monetize its retained interest in Sandisk and reduce its debt, it completed a number of transactions, including a debt-for-equity exchange, equity-for-equity exchanges, and the private settlement of a portion of our convertible note obligations. In connection with these transactions, the company recognized costs primarily related to a discount given to the counterparty of the transaction. The company believes these costs do not reflect the company’s operating results and are not indicative of the underlying performance of its business.
11


Income tax adjustments. Income tax adjustments represent the difference between income taxes based on a forecasted annual GAAP tax rate and a forecasted annual non-GAAP tax rate, which have been adjusted to account for the tax effects of items excluded from non-GAAP pre-tax income as well as the tax effects of non-recurring and period-specific tax items. These adjustments are excluded because the company believes that they are not indicative of the underlying performance of its ongoing business.

Other adjustments. From time to time, the company records costs, charges, and benefits 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.

As described above, the company also presents the following non-GAAP financial measures:

Non-GAAP diluted weighted average shares. Beginning with the three months ended October 3, 2025, the company calculates non-GAAP diluted net income from continuing operations per common share based on non-GAAP diluted weighted average shares and has also adjusted the prior year periods to conform to the new presentation. Management uses non-GAAP diluted weighted average shares to evaluate — in addition to the potential dilution due to the outstanding restricted stock units and the dilution from the 2028 convertible notes that are included in GAAP diluted weighted average shares — the benefit expected to be provided by existing capped call transactions entered into in connection with the 2028 convertible notes to offset the dilutive impact of the convertible notes, up to their capped limit. In periods where the quarterly average stock price per share exceeds the conversion price of the 2028 convertible notes, non-GAAP diluted weighted average shares includes the anti-dilutive impact of the company’s capped call transactions, up to the then-applicable capped call price per share.

Free cash flow. Free cash flow is defined as cash flows provided by operating activities less purchases of property, plant and equipment, net, and the pre-Separation activity related to Flash Ventures, net. The company considers free cash flow generated in any period to be a key indicator of the underlying health of the business.

Non-GAAP Guidance
This press release contains forward-looking estimates of certain non-GAAP financial measures for the fiscal first quarter of 2027 (“Q1FY27”). We provide these non-GAAP measures to investors on a prospective basis because certain information necessary to reconcile such guidance to GAAP is difficult to predict and estimate or cannot be allocated or quantified with certainty and is often dependent on future events that may be uncertain or outside of our control. Accordingly, reconciliations of these non-GAAP financial measures to the most directly comparable GAAP financial measures are not available without unreasonable effort.

The known adjustments to our non-GAAP guidance for Q1FY27 and details on how our non-GAAP tax rate guidance is determined are provided below:
Non-GAAP gross margin guidance excludes stock-based compensation expense, totaling approximately $10 million.
Non-GAAP operating expenses guidance excludes stock-based compensation and other expenses, totaling approximately $60 million.
Non-GAAP diluted net income per common share guidance excludes the items described above, totaling approximately $70 million.
Non-GAAP tax rate guidance is determined based on a percentage of non-GAAP pre-tax income or loss. Our estimated non-GAAP tax rate may differ from our GAAP tax rate due to: (i) the tax effects of items excluded from our non-GAAP pre-tax income or loss; (ii) the tax effects of non-recurring and period-specific items; and (iii) our accrual of GAAP income taxes and non-GAAP income taxes, which are calculated in each interim period using our best estimates of income taxes for the full year.
Non-GAAP diluted weighted average shares guidance reflects no material benefit expected to be provided by existing capped call transactions entered into in connection with our convertible senior notes due 2028.

In addition to the adjustments to our forward-looking non-GAAP financial measures described above, reconciliations to comparable forward-looking GAAP financial measures may include additional adjustments that are not available without unreasonable effort. These additional adjustments may include unanticipated changes in our GAAP effective tax rate, unanticipated charges related to business realignment, unanticipated litigation matters, and other unanticipated gains, losses, and impairments, and other unanticipated items not reflective of ongoing operations. Our forward-looking estimates of non-GAAP measures of our financial performance may differ materially from our actual results and should not be relied upon as statements of fact.
