Basis of Presentation and Use of Estimates

The accompanying Consolidated Financial Statements are unaudited and have been prepared in accordance with U.S. Generally Accepted Accounting Principles ("U.S. GAAP") and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC"). In our opinion, they include all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of results for the interim periods. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted as permitted by the SEC's rules and regulations for interim reporting. These Consolidated Financial Statements should be read in conjunction with our audited financial statements and notes thereto included in our Annual Report on Form10-K for the year ended* December 28, 2024 ("*2024 10-K").

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and judgments affecting the amounts reported in our consolidated condensed financial statements and the accompanying notes. We base our estimates and judgments on historical experience, knowledge of current conditions, and our beliefs of what could occur in the future considering available information. While we believe that our estimates, assumptions, and judgments are reasonable, they are based on information available when made, and because of the uncertainty inherent in these matters, the actual results that we experience* may*differ materially from these estimates under different assumptions or conditions. We evaluate our estimates and judgments on an ongoing basis.

We describe our accounting methods and practices in more detail in our2024 10-K. There have beenno changes to the significant accounting policies, procedures, or general information described in our2024 10-K that have had a material impact on our consolidated condensed financial statements and the accompanying notes. Certain prior year balances have been reclassified to conform to the current year’s presentation.

Concentrations of Risk

Potential exposure to concentrations of risk* mayimpact revenue and trade accounts receivable. Sales to distributors have historically accounted for a significant portion of our total revenue. Revenue attributable to distributors as a percentage of total revenue was 83% and 95% for thethird* quarters of fiscal2025 and2024, respectively and 82% and 91% for thefirst nine months of fiscal2025 and2024, respectively. Distributors also account for a substantial portion of our net accounts receivable.

New Accounting Pronouncements

In* December 2023,the FASB issued ASU2023*-09, Income Taxes (Topic740*) Improvements to Income Tax Disclosures*, which require greater disaggregation of income tax disclosures. ASU2023-09 aims to improve an entity’s income tax disclosures around its effective rate reconciliation, income taxes paid by jurisdiction, disaggregation of income before income taxes and income tax expense. The guidance in this update is effective for fiscal years beginning after* December 15, 2024,but retrospective application is permitted. Early adoption is permitted. We are currently evaluating the future effect of the adoption of this ASU will have on our consolidated financial statements and disclosures, and donot* expect it will have a material impact on our consolidated results.

In* November 2024,the FASB issued ASU2024*-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic220*-40): Disaggregation of Income Statement Expenses*. This new guidance requires public entities to provide disaggregated disclosures, in the notes to the financial statements, of certain categories of expenses that are included in expense line items on the face of income statement. The ASU* maybe applied prospectively or retrospectively and is effective for fiscal years beginning after December 15, 2026and for interim periods beginning after December 15, 2027.*Early adoption is permitted. We are currently evaluating the impact of adoption of this new guidance on our consolidated financial statements and disclosures.

In* September 2025,the FASB issued ASU2025*-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic350*-40): Targeted Improvements to the Accounting for Internal-Use Software*. This ASU is intended to simplify the recognition and disclosure guidance related to capitalized internal-use software costs by removing all references to software development project stages and introducing a more judgment-based framework. ASU2025-06 is effective for fiscal years beginning after* December 15, 2027,and for interim periods within those fiscal years, with early adoption permitted as of the beginning of a fiscal year. This standard may*be applied prospectively, retrospectively, or via a modified prospective transition method. We are currently evaluating the impact of adoption of this new guidance on our consolidated financial statements and disclosures.

Note2 - Net Income per Share

We compute basic earnings per share based on the weighted average number of shares of common stock outstanding during the period. We compute diluted earnings per share based on the weighted average number of shares of common stock outstanding plus potentially dilutive shares of common stock outstanding during the period, if applicable. Potentially dilutive shares of common stock from employee equity incentive awards are determined by applying the treasury stock method to the assumed exercise of outstanding stock options, the assumed vesting of outstanding restricted stock units ("RSUs") and restricted stock awards ("RSAs"), and the assumed issuance of common stock under the stock purchase plan.

Our calculation of potentially dilutive shares includes the number of shares from our equity awards with market conditions or performance conditions that would be issuable under the terms of such awards at the end of the reporting period. For equity awards with a market condition, the number of shares included in the diluted share count as of the end of each period presented is determined by measuring the achievement of the market condition as of the end of the respective reporting periods. For equity awards with a performance condition, the number of shares that qualified for vesting as of the end of each period presented are included in the diluted share count when the condition for their issuance was satisfied by the end of the respective reporting periods. See"Note9 - Stock-Based Compensation" to our consolidated financial statements for further discussion of our equity awards with market conditions or performance conditions.

A summary of basic and diluted Net income per share is presented in the following table:

The computation of diluted Net income per share excludes the effects of employee equity incentive awards that are antidilutive, aggregating approximately 0.7 million and 2.4 million shares for thethird quarters of fiscal2025 and2024, respectively, and approximately 0.9 million and 1.0 million shares for thefirst nine months of fiscal2025 and2024, respectively.
