For the first six months of fiscal 2026 and 2025, we recorded income tax expense of approximately $3.3 million and $5.1 million, respectively. Income taxes for the three- and six-month periods ended July 4, 2026 and June 28, 2025 represent tax at the federal, state, and foreign statutory tax rates in addition to federal tax credits, stock-based compensation and other non-deductible items in federal, state, and foreign jurisdictions. The difference between the U.S. federal statutory tax rate of 21% and our effective tax rates for the three and six months ended July 4, 2026 and the three and six months ended June 28, 2025 resulted primarily from stock-based compensation expense, partially offset by foreign rate differentials.

The portion of our uncertain tax positions (including penalties and interest) recorded as a liability was $2.1 million at both July 4, 2026 and January 3, 2026, and is included as a component of Other long-term liabilities on our Consolidated Balance Sheets.

Significant Accounting Policies (Policies)	6 Months Ended
Significant Accounting Policies (Policies)	Jul. 04, 2026
Accounting Policies [Abstract]
Basis of Accounting and Use Of Estimates, Policy [Policy Text Block]	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 Form 10-K for the year ended January 3, 2026 ("2025 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 our 2025 10-K. Other than as described below, there have been no changes to the significant accounting policies, procedures, or general information described in our 2025 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. During 2026, we initiated foreign currency hedging activities and, as a result, include the below additional accounting policies related to fair value and financial instruments:
Fair Value Measurement, Policy [Policy Text Block]	*Fair Value Accounting Policy* We apply the provisions of ASC 820, Fair Value Measurement (ASC 820), to our assets and liabilities that we are required to measure at fair value pursuant to other accounting standards, including our derivative financial instruments. When determining fair value, we consider the principal or most advantageous market in which we would transact, as well as assumptions that market participants would use when pricing the asset or liability. All our financial assets and liabilities are measured and recorded at fair value on a recurring basis.
Derivatives, Policy [Policy Text Block]	*Financial Instrument Accounting Policy* In Fiscal 2026, we began to use derivative financial instruments to manage our exposure to foreign currency exchange rate risk. We have entered into foreign currency forward contracts in relation to certain operating expense activities denominated in currencies other than the U.S. Dollar, and these contracts generally mature within 12 months. We account for these instruments in accordance with ASC 815, Derivatives and Hedging (ASC 815), which requires that every derivative instrument be recorded as either an asset or liability measured at its fair value as of each reporting date. ASC 815 also requires that changes in the fair values of our derivatives be recognized in earnings, unless specific hedge accounting and documentation criteria are met. The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and the resulting designation. Our foreign currency contracts are designated as cash flow hedges. As such, we record the change in fair value of a derivative in Other comprehensive income (loss), and the change is reclassified to earnings in the period that the hedged item affects earnings. As of July 4, 2026, the notional value of our outstanding foreign currency forward contracts designated as cash flow hedges was $44.9 million.
Fiscal Period, Policy [Policy Text Block]	Fiscal Reporting Periods We report based on a 52 or 53-week fiscal year ending on the Saturday closest to December 31. Our fiscal 2026 will be a 52-week year and will end on January 2, 2027, and our fiscal 2025 was a 53-week year that ended January 3, 2026. Our second quarter of fiscal 2026 and second quarter of fiscal 2025 ended on July 4, 2026 and June 28, 2025, respectively. All references to quarterly financial results are references to the results for the relevant 13-week or 26-week fiscal period.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Concentrations of Risk Potential exposure to concentrations of risk may impact revenue, trade accounts receivable, cash and cash equivalents, and supply of wafers for our new products. 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 95% and 84% for the second quarter of fiscal 2026 and 2025, respectively, and 95% and 81% for the first six months of fiscal 2026 and 2025, respectively. Distributors also account for a substantial portion of our net accounts receivable. Our two largest distributors account for 49% and 39%, respectively, of net accounts receivable at July 4, 2026 and 62% and 28%, respectively, of net accounts receivable at January 3, 2026. Concentration of credit risk with respect to trade accounts receivable is mitigated by our credit and collection process including active management of collections, credit limits, routine credit evaluations for essentially all customers, and secure transactions with letters of credit or advance payments where appropriate. We regularly review our allowance for doubtful accounts and the aging of our accounts receivable. We limit our risk exposure related to cash and cash equivalents by placing our cash with high credit quality financial institutions. At times, such deposits may exceed Federal Deposit Insurance Corporation insurance limits. We have not experienced any losses on our deposits of cash and cash equivalents. We rely on a limited number of foundries for our wafer purchases and partners for our assembly and test operations. We seek to mitigate the concentration of supply risk by establishing, maintaining, and managing multiple foundry and partner relationships; however, certain of our products are sourced from a single supplier and changing from one supplier to another can have a significant cost, or create delays in production or shipments, among other factors.
New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Pronouncements 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. 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 the income statement. The ASU may be applied prospectively or retrospectively and is effective for fiscal years beginning after December 15, 2026 and 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 ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): 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. ASU 2025-06 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.

Note 8 - Intangible Assets

In connection with our previous acquisitions and purchases of certain intellectual property assets, we have recorded identifiable intangible assets related to existing technology, customer relationships, and trade name / trademarks. We amortize the intangible assets using the straight-line method over their estimated useful lives of 7 to 10 years. Additionally, we have entered into license agreements for third-party technology and recorded them as intangible assets. These licenses are being amortized to Research and development expense over their estimated useful lives of 1 to 10 years. In the second quarter of fiscal 2026, we licensed certain third-party technology under an agreement valued at $16.1 million, and we have determined that this license has a useful life of 10 years. On our Consolidated Balance Sheets at July 4, 2026 and January 3, 2026, Intangible assets, net are shown net of accumulated amortization of $166.9 million and $165.7 million, respectively.

We recorded amortization expense related to intangible assets on the Consolidated Statements of Operations as presented in the following table:

Market-Based and Performance-Based Stock Compensation

In the second quarter of fiscal 2026, we granted awards of restricted stock units ("RSUs") with a market condition to members of our executive leadership team ("ELT") and certain other senior executives. Under the terms of these grants, the RSUs with a market condition vest over a three-year period based on the Company’s total shareholder return ("TSR") relative to the Russell 3000 index. The awards may vest at 250% or 200% (depending on the executive) if the 75^th percentile of the market condition is achieved, at 100% if the 55^th percentile of the market condition is achieved, and at 0% if the relative TSR is below the 25^th percentile. Vesting is interpolated on a straight-line basis for market condition achievement between the 25^th and 75^th percentiles. For grants to members of the ELT, the market condition will be measured on the third anniversary of the grant date. For grants to other senior executives, the market condition will be measured equally on the first, second, and third anniversary of the grant date, using calendar years 2026, 2027, and 2028, respectively, as the measurement period for each of the three tranches.

In the first six months of fiscal 2026, certain awards with a market condition granted in prior fiscal years vested. During the first quarter of fiscal 2026, the market condition for awards granted to certain executives in the first quarter of fiscal 2023 exceeded the 25th percentile of their TSR condition, and these awards vested at 87%. Also during the first quarter of fiscal 2026, the market condition for the first tranche of awards granted to certain executives in the first quarter of fiscal 2025 exceeded the 75th percentile of their TSR condition, and these awards vested at 200%. During the second quarter of fiscal 2026, the market condition for the second tranche of awards granted to a certain executive in the third quarter of fiscal 2024 exceeded the 75th percentile of their TSR condition, and these awards vested at 200%.

For our awards with a market condition or performance condition, we incurred stock-based compensation expense of $22.3 million and $5.6 million, respectively, in the second quarter of fiscal 2026 and 2025 and $32.9 million and $9.8 million, respectively, in the first six months of fiscal 2026 and 2025. Stock-based compensation expense for the second quarter and first six months of 2026 included $9.6 million resulting from updates to the expected achievement of certain awards with a performance condition. These amounts are recorded as components of total stock-based compensation expense.

The following table summarizes the activity for our awards with a market condition or performance condition:

(Shares in thousands)	*Total*

Incentive Compensation Settled In Equity

Under our Corporate Incentive Plan, incentive payments may be made in cash or in shares of our Common Stock, or a combination of both, as determined at the discretion of the Compensation Committee of our Board of Directors. To the extent incentive payments are settled in equity under the 2023 Equity Incentive Plan, the number of shares of our Common Stock to be issued is determined by dividing the eligible employee’s incentive payment value by the 30-calendar day average closing price of our Common Stock during the period ending the day before the date of settlement. Under this methodology, the value of the shares of our Common Stock issued on the settlement date could differ from the incentive payment value accrued. Any shares of our Common Stock issued to settle incentive payments under this plan vest immediately upon issuance.

Our results for the first six months of fiscal 2026 include our settlement in the first quarter of fiscal 2026 of a portion of the incentive compensation accrued during fiscal 2025 by issuing shares of our Common Stock with a total value of $5.8 million to certain employees.

Earnings Per Share [Text Block]

Note 2 - 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 "Note 9 - 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:

Note 14 - Subsequent Event

On July 27, 2026, the Company completed its acquisition of AMI (the “AMI Acquisition”). Under the terms of the Agreement and Plan of Merger, dated May 4, 2026 (the “Merger Agreement”), by and among the Company, AMI, THL AMI Aggregator, LP (“THL”) and the other parties thereto, the Company acquired for total consideration of approximately $1 billion in cash and approximately 5.2 million shares of Company common stock and restricted stock units, subject to adjustments set forth in the Merger Agreement, including for AMI’s working capital, transaction expenses, cash and indebtedness as of the closing (the “Aggregate Consideration”). A portion of the Aggregate Consideration will be held in escrow to serve as security for potential adjustments to the Aggregate Consideration and indemnification claims under the Merger Agreement following the completion of the AMI Acquisition. In connection with the completion of the AMI Acquisition, the Company borrowed $925 million aggregate principal amount of loans under the delayed draw term loan facility pursuant to the 2026 Credit Agreement, as discussed in "Note 5 – Long-Term Debt". The Company is granting additional Company restricted stock units to AMI employees in connection with the completion of the AMI Acquisition, subject to certain vesting and other terms and conditions.

In connection with the AMI Acquisition, the Company and THL entered into a registration rights agreement (the “Registration Rights Agreement”), which provides for customary registration rights with respect to the shares of the Company’s common stock issued to THL as consideration for the AMI Acquisition. Pursuant to the Registration Rights Agreement, THL and its affiliates will collectively be entitled to two underwritten block trades. In addition, as part of the AMI Acquisition, THL and the other stockholders of AMI are agreeing to certain transfer restrictions with respect to the shares of the Company’s common stock issued as consideration for the AMI Acquisition, with 25% of the shares released from the transfer restrictions upon the completion of each successive 90-day period following the completion of the AMI Acquisition and a release in full from the transfer restrictions on July 27, 2027, the one-year anniversary of the completion of the AMI Acquisition.

Contingencies Disclosure [Text Block]

Note 12 - Contingencies

Legal Proceedings

From time to time, we are exposed to certain additional asserted and unasserted potential claims. We review the status of each significant matter and assess its potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and a range of possible losses can be estimated, we then accrue a liability for the estimated loss. Legal proceedings are subject to uncertainties, and the outcomes are difficult to predict. Because of such uncertainties, accruals are based only on the best information available at the time. As additional information becomes available, we reassess the potential liability related to pending claims and litigation and may revise estimates.

- Definition

The entire disclosure for loss and gain contingencies. Describes any existing condition, situation, or set of circumstances involving uncertainty as of the balance sheet date (or prior to issuance of the financial statements) as to a probable or reasonably possible loss incurred by an entity that will ultimately be resolved when one or more future events occur or fail to occur, and typically discloses the amount of loss recorded or a range of possible loss, or an assertion that no reasonable estimate can be made.

Our leases have remaining lease terms of less than 1 year up to 9 years, some of which include options to extend for up to 5 years, and some of which include options to terminate within 1 year. The weighted-average remaining lease term was 6.0 years and the weighted-average discount rate was 4.9% as of July 4, 2026.

We recorded fixed operating lease expenses of $2.2 million and $2.3 million for the second quarter of fiscal 2026 and 2025, respectively, and $4.6 million and $4.4 million for the first six months of fiscal 2026 and 2025, respectively.

Notes to Financial Statements

Organization, Consolidation, Basis of Presentation, Business Description and Accounting Policies [Text Block]

Note 1 - Basis of Presentation

Lattice Semiconductor Corporation and its subsidiaries (“Lattice,” the “Company,” “we,” “us,” or “our”) develop technologies that we monetize through differentiated programmable logic semiconductor products, silicon-enabling products, system solutions, design services, and technology licenses.

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 Form 10-K for the year ended January 3, 2026 ("2025 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 our 2025 10-K. Other than as described below, there have been no changes to the significant accounting policies, procedures, or general information described in our 2025 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.

During 2026, we initiated foreign currency hedging activities and, as a result, include the below additional accounting policies related to fair value and financial instruments:

Fair Value Accounting Policy

We apply the provisions of ASC 820, Fair Value Measurement (ASC 820), to our assets and liabilities that we are required to measure at fair value pursuant to other accounting standards, including our derivative financial instruments. When determining fair value, we consider the principal or most advantageous market in which we would transact, as well as assumptions that market participants would use when pricing the asset or liability. All our financial assets and liabilities are measured and recorded at fair value on a recurring basis.

Financial Instrument Accounting Policy

In Fiscal 2026, we began to use derivative financial instruments to manage our exposure to foreign currency exchange rate risk. We have entered into foreign currency forward contracts in relation to certain operating expense activities denominated in currencies other than the U.S. Dollar, and these contracts generally mature within 12 months. We account for these instruments in accordance with ASC 815, Derivatives and Hedging (ASC 815), which requires that every derivative instrument be recorded as either an asset or liability measured at its fair value as of each reporting date.

ASC 815 also requires that changes in the fair values of our derivatives be recognized in earnings, unless specific hedge accounting and documentation criteria are met. The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and the resulting designation. Our foreign currency contracts are designated as cash flow hedges. As such, we record the change in fair value of a derivative in Other comprehensive income (loss), and the change is reclassified to earnings in the period that the hedged item affects earnings.

As of July 4, 2026, the notional value of our outstanding foreign currency forward contracts designated as cash flow hedges was $44.9 million.

Fiscal Reporting Periods

We report based on a 52 or 53-week fiscal year ending on the Saturday closest to December 31. Our fiscal 2026 will be a 52-week year and will end on January 2, 2027, and our fiscal 2025 was a 53-week year that ended January 3, 2026. Our second quarter of fiscal 2026 and second quarter of fiscal 2025 ended on July 4, 2026 and June 28, 2025, respectively. All references to quarterly financial results are references to the results for the relevant 13-week or 26-week fiscal period.

Concentrations of Risk

Potential exposure to concentrations of risk may impact revenue, trade accounts receivable, cash and cash equivalents, and supply of wafers for our new products. 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 95% and 84% for the second quarter of fiscal 2026 and 2025, respectively, and 95% and 81% for the first six months of fiscal 2026 and 2025, respectively.

Distributors also account for a substantial portion of our net accounts receivable. Our two largest distributors account for 49% and 39%, respectively, of net accounts receivable at July 4, 2026 and 62% and 28%, respectively, of net accounts receivable at January 3, 2026. Concentration of credit risk with respect to trade accounts receivable is mitigated by our credit and collection process including active management of collections, credit limits, routine credit evaluations for essentially all customers, and secure transactions with letters of credit or advance payments where appropriate. We regularly review our allowance for doubtful accounts and the aging of our accounts receivable.

We limit our risk exposure related to cash and cash equivalents by placing our cash with high credit quality financial institutions. At times, such deposits may exceed Federal Deposit Insurance Corporation insurance limits. We have not experienced any losses on our deposits of cash and cash equivalents.

We rely on a limited number of foundries for our wafer purchases and partners for our assembly and test operations. We seek to mitigate the concentration of supply risk by establishing, maintaining, and managing multiple foundry and partner relationships; however, certain of our products are sourced from a single supplier and changing from one supplier to another can have a significant cost, or create delays in production or shipments, among other factors.

New Accounting Pronouncements

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. 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 the income statement. The ASU may be applied prospectively or retrospectively and is effective for fiscal years beginning after December 15, 2026 and 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 ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): 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. ASU 2025-06 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.

Disaggregation of Revenue

The following tables provide information about revenue from contracts with customers disaggregated by channel and by geographical market. Revenue is attributed to geographic regions based on the ship-to location of the customer. The Greater China geography includes revenue associated with shipments to both Hong Kong and mainland China. Products shipped to Hong Kong may subsequently be transferred to mainland China or other destinations, and products shipped to mainland China may similarly move through intermediary locations.

Long-Term Debt [Text Block]

Note 5 - Long-Term Debt

On June 30, 2026, we entered into a Second Amended and Restated Credit Agreement (the "2026 Credit Agreement"), which provides for a senior secured revolving loan facility ("revolving loans") in an aggregate principal amount of $200 million dollars and a senior secured delayed draw term loan facility ("term loans") in an aggregate principal amount of $950 million dollars (collectively, "long-term debt"). The 2026 Credit Agreement amended and restated in its entirety our Amended and Restated Credit Agreement, dated as of September 1, 2022 (the “2022 Credit Agreement”). On July 27, 2026, in connection with the completion of our acquisition of AMI, we borrowed $925 million under the term loans pursuant to the 2026 Credit Agreement, the proceeds of which were used to pay a portion of the cash purchase price consideration for the AMI acquisition (including refinancing outstanding indebtedness of AMI) and to pay fees, commissions, and expenses incurred in connection with the AMI acquisition. Following the borrowing of $925 million under the term loans, the remaining $25 million of undrawn commitments under the term loans expired on the closing date of the acquisition. Fees incurred in association with the 2026 Credit Agreement totaled $6.6 million through July 4, 2026.

The term loans are payable in required quarterly installments beginning with the first full fiscal quarter after the term loans are borrowed, equal to 1.250% of the original principal amount of the term loans for the first four fiscal quarters following the funding date, 1.875% of the original principal amount of the term loans for the fifth through twelfth fiscal quarters following the funding date, and 2.5% of the original principal amount of the term loans for each fiscal quarter thereafter, with the remaining principal amount and accrued and unpaid interest being due and payable on June 30, 2031. The term loans may be prepaid by the Company at any time in whole or in part, subject to certain minimum thresholds, without penalty or premium, subject to customary breakage costs for certain types of loans. The term loans are subject to customary mandatory prepayment requirements.

The proceeds of the revolving loans under the 2026 Credit Agreement may be used for working capital and general corporate purposes. Revolving loans may be repaid and reborrowed at our discretion, with any remaining outstanding principal amount due and payable on the maturity date of the revolving loans on June 30, 2031.

The 2026 Credit Agreement contains customary affirmative and negative covenants, including covenants limiting the ability of the Company to, among other things, incur debt, grant liens, undergo certain fundamental changes, make investments, make certain restricted payments, dispose of assets, enter into transactions with affiliates, and enter into burdensome agreements, in each case, subject to limitations and exceptions set forth in the 2026 Credit Agreement. We are also required to maintain compliance with a consolidated total net leverage ratio and a consolidated interest coverage ratio, in each case, determined in accordance with the terms of the 2026 Credit Agreement.

Loans under our 2026 Credit Agreement accrue interest at a per annum rate based on ranges determined by our consolidated total leverage ratio. At our option, interest accrues at either (a) the base rate (as defined in the 2026 Credit Agreement) plus a margin ranging from 0.00% and 0.75%, or (b) a term Secured Overnight Financing Rate ("SOFR") for interest periods of 1, 3 or 6 months plus a margin ranging from 1.00% and 1.75%. Interest is payable quarterly in arrears with respect to borrowings bearing interest at the base rate or on the last day of an interest period, but at least every three months, with respect to borrowings bearing interest at the term SOFR rate.

At July 4, 2026, we had no borrowings outstanding under the 2026 Credit Agreement, and at January 3, 2026, we had no borrowings outstanding under the 2022 Credit Agreement.

Prior to entering into the 2026 Credit Agreement and for the period in which the amendment was being prepared, we arranged for a commitment letter for a 1-year Senior Secured Bridge Facility (the "bridge facility"). Fees associated with the bridge facility commitments totaled $5.6 million, of which $0.9 million was amortized to Interest income (expense), net on our Consolidated Statements of Operations. With the execution of the 2026 Credit Agreement, the remaining $4.7 million of unamortized debt costs associated with the bridge facility and $0.2 million of unamortized debt costs associated with the 2022 Credit Agreement were expensed and are included in Other income (expense), net on our Consolidated Statements of Operations.
