Note Regarding Forward-Looking Statements

This Quarterly Report on Form 10-Q contains forward-looking statements that involve estimates, assumptions, risks, and uncertainties. Any statements about our expectations, beliefs, plans, objectives, assumptions, or future events or performance are not historical facts and may be forward-looking. We use words or phrases such as “anticipate,” “believe,” “could,” “estimate,” “expect,” “intend,” “plan,” "possible," “predict,” “projects,” “may,” “will,” “should,” “continue,” “ongoing,” “future,” “potential,” and similar words or phrases to identify forward-looking statements.

Forward-looking statements include, but are not limited to, statements about: our target or expected financial performance and our ability to achieve those results; the impact of increasing trade or travel restrictions or increasing tariffs on the export and import of products between the U.S. and other countries; the impact of tariffs, trade sanctions, license requirements or similar actions on our suppliers, distributors, channel partners, and customers, including the impact on the costs of our products, the products into which they are integrated, and the impact on demand due to costs and uncertainty; our significant reliance on a small number of distributors; the impact of inflationary pressures; future impacts of the ongoing military conflicts between Ukraine and Russia, and in the Middle East, and the outbreak of new, or expansion of current, military conflicts or terrorism; the impact of any deterioration in relations between Taiwan and China, and other factors affecting military, political, or economic conditions in Taiwan or elsewhere in Asia; our business strategy; our opportunities to increase our addressable market; our expectations and strategies regarding market trends and opportunities, including market drivers such as wireless and wireline communications infrastructure deployments, data center servers and networking equipment, client computing platforms, industrial Internet of Things, factory automation, robotics, automotive electronics, smart homes, prosumers, and other applications; our expectations of the impact of the uncertain trade environment, including tariffs, on customer demand; the impact of artificial intelligence (“AI”), including our expectations regarding the growth of AI-related revenue; our expectations regarding our customer base and the impacts of our customers’ actions on our business; our expectations regarding both new and existing product offerings; our gross margin growth and our strategies to achieve gross margin growth and other financial results; our future investments in research and development; our ability to attract and retain personnel and their importance to our performance; future financial results or accounting treatments; our judgments involved in accounting matters, including revenue recognition, inventories and cost of revenue, and income taxes; actions we may take regarding the design and continued effectiveness of our internal controls over financial reporting; our use of cash; our beliefs regarding the adequacy of our liquidity, capital resources and facilities; whether we will consider and act upon acquisition opportunities to extend our product, technology and product offerings, and the impact of such opportunities on our business; our expectations regarding taxes, including unrecognized tax benefits, and tax adjustments and allowances; whether we will pursue future stock repurchases and how any future repurchases will be funded; the future price volatility of our stock and the effects of that volatility; our ability to prevent and respond to information technology system failures, security breaches and incidents, cyberattacks or fraud, and the occurrence and impact of such cybersecurity incidents; the costs of mitigating cybersecurity risks; the impact of laws and regulations addressing privacy, data protection, and cybersecurity and our ability to comply with the same; our ability to comply with other laws and regulations, including those that are trade and tariff related, the costs of such compliance, and costs incurred if we fail to comply with such laws and regulations; our beliefs regarding legal or administrative proceedings; and impacts of global pandemics, epidemics, and other public health matters and actions of governments, businesses, and individuals in response to these situations.

These forward-looking statements are based on estimates and assumptions that are subject to risks and uncertainties that could cause actual results to differ materially from those statements expressed in the forward-looking statements. The key factors, among others, that could cause our actual results to differ materially from the forward-looking statements include global economic conditions and uncertainty, including as a result of trade-related restrictions or tariffs or uncertainty regarding trade restrictions and tariffs, inflationary pressures, or the effect of any downturn in the economy on capital markets and credit markets; the macroeconomic climate and effects of global military conflicts and actions of governments, businesses, and individuals in response to these situations, the effects of which may give rise to or amplify the risks associated with many of these factors listed here; our ability to attract and retain key personnel; and other factors more fully described herein or that are otherwise described from time to time in our filings with the Securities and Exchange Commission ("SEC"), including, but not limited to, the items discussed in Part I, Item 1A, “Risk Factors,” in our Annual Report on Form 10-K for the fiscal year ended December 28, 2024 filed with the SEC on February 14, 2025 and any additional or updated risk factors discussed in any subsequent Quarterly Report on Form 10-Q filed since that date.

You should not unduly rely on forward-looking statements because our actual results could differ materially from those expressed by us. In addition, any forward-looking statement applies only as of the date of this filing. We do not plan to, and undertake no obligation to, update any forward-looking statements to reflect new information or new events, circumstances or developments, or otherwise.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

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 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 our 2024 10-K. There have been no changes to the significant accounting policies, procedures, or general information described in our 2024 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.

Fiscal Reporting Periods

We report based on a 52 or 53-week fiscal year ending on the Saturday closest to December 31. Our fiscal 2025 will be a 53-week year and will end on January 3, 2026, and our fiscal 2024 was a 52-week year that ended December 28, 2024. Our third quarter of fiscal 2025 and third quarter of fiscal 2024 ended on September 27, 2025 and September 28, 2024, respectively. All references to quarterly or year-to-date financial results are references to the results for the relevant 13-week or 39-week fiscal period.

Concentrations of Risk

Potential exposure to concentrations of risk may impact 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 the third quarters of fiscal 2025 and 2024, respectively and 82% and 91% for the first nine months of fiscal 2025 and 2024, respectively. Distributors also account for a substantial portion of our net accounts receivable. At September 27, 2025, our two largest distributors accounted for 52% and 35% of net accounts receivable, and at December 28, 2024, our two largest distributors accounted for 45% and 36% of net accounts receivable.

New Accounting Pronouncements

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740) Improvements to Income Tax Disclosures, which require greater disaggregation of income tax disclosures. ASU 2023-09 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 do not expect it will have a material impact on our consolidated results.

Table of Contents

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 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 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:

|  | Three Months Ended |  |  | Nine Months Ended |
|  | September 27, |  |  | September 28, |  |  | September 27, |  |  | September 28, |
(In thousands, except per share data) |  | 2025 |  |  | 2024 |  |  | 2025 |  |  | 2024 |
Net income |  | $ | 2,794 |  |  | $ | 7,190 |  |  | $ | 10,729 |  |  | $ | 44,617 |
Shares used in basic Net income per share |  |  | 136,877 |  |  |  | 137,709 |  |  |  | 137,224 |  |  |  | 137,577 |
Dilutive effect of employee equity incentive awards |  |  | 1,226 |  |  |  | 185 |  |  |  | 845 |  |  |  | 697 |
Shares used in diluted Net income per share |  |  | 138,103 |  |  |  | 137,894 |  |  |  | 138,069 |  |  |  | 138,274 |
Basic Net income per share |  | $ | 0.02 |  |  | $ | 0.05 |  |  | $ | 0.08 |  |  | $ | 0.32 |
Diluted Net income per share |  | $ | 0.02 |  |  | $ | 0.05 |  |  | $ | 0.08 |  |  | $ | 0.32 |

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 the third quarters of fiscal 2025 and 2024, respectively, and approximately 0.9 million and 1.0 million shares for the first nine months of fiscal 2025 and 2024, respectively.

Note 5 - Long-Term Debt

On September 1, 2022, we entered into an Amended and Restated Credit Agreement (the “2022 Credit Agreement”), which provides for a five-year secured revolving loan facility with an aggregate principal amount of up to $350 million.

The revolving loans under the 2022 Credit Agreement may be repaid and reborrowed at our discretion, with any remaining outstanding principal amount due and payable on the maturity date of the revolving loan on September 1, 2027. At September 27, 2025 and December 28, 2024, we had no borrowings outstanding under the 2022 Credit Agreement. We pay a quarterly commitment fee of 0.20% on the unused portion of the revolving facility.

Note 6 - Restructuring

Under the Q3 2024 Plan, which is described in our 2024 10-K, we incurred restructuring costs of approximately $0.8 million and $2.4 million in the third quarter and first nine months, respectively, of fiscal 2025, and approximately $6.5 million in both the third quarter and first nine months of fiscal 2024. Under this plan, approximately $10.0 million of total costs have been incurred through September 27, 2025. The Q3 2024 Plan is expected to be largely complete by the end of fiscal year 2025.

Under the Q3 2023 Plan, which is described in our 2024 10-K, we incurred no restructuring costs during the first nine months of fiscal 2025, and restructuring costs of approximately $0.3 million and $5.3 million during the third quarter and first nine months, respectively, of fiscal 2024. Under this plan, approximately $7.3 million of total costs have been incurred through September 27, 2025. All actions planned under the Q3 2023 Plan have been implemented.

Other restructuring activity in the periods presented consisted of expense adjustments on previous plans. Costs and adjustments on restructuring plans are recorded to Restructuring and other on our Consolidated Statements of Operations. The restructuring accrual balance is presented in Accrued liabilities and in Other long-term liabilities on our Consolidated Balance Sheets.

Note 8 - Intangible Assets

In connection with our past acquisitions and purchases of certain intellectual property assets, we have recorded identifiable intangible assets. We also enter into license agreements for third-party technology and record them as intangible assets. These licenses are being amortized to Research and development expense over their estimated useful lives. On our Consolidated Balance Sheets at September 27, 2025 and December 28, 2024, Intangible assets, net are shown net of accumulated amortization of $165.2 million and $163.5 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 first quarter of fiscal 2025, we granted awards of RSUs with a market condition to certain 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, which condition is measured for the grants on either the third anniversary of the grant date, or equally on the first, second, and third anniversary of the grant date for certain recently hired executives. The awards may vest at 200% if the 75th percentile of the market condition is achieved, with 100% of the units vesting at the 55th percentile, zero vesting if relative TSR is below the 25th percentile, and vesting scaling for achievement between the 25th and 75th percentile.

In the first quarter of fiscal 2025, we also granted awards of RSUs with a performance condition to certain executives. Under the terms of these grants, the RSUs with a performance condition will vest if the Company achieves year-over-year revenue growth in excess of the Gartner Non-Memory Semiconductor Revenue Growth benchmark, and the number of shares that vest will scale based on achievement of year-over-year revenue growth compared to certain targets, with maximum vesting up to 250%.

During the first quarter of fiscal 2025, the Compensation Committee of the Board of Directors approved a modification to the performance condition periods and vesting criteria associated with these revenue growth performance awards and similar awards that were granted to certain executives in fiscal 2024 to align the awards with the Company's growth strategy. The modification extended the beginning and end dates of each measurement period by one year, such that the performance condition will be measured annually after each fiscal year-end for one-fourth of the grants with the first measurement period beginning in fiscal 2026 and the last measurement period ending at the end of fiscal 2029. Additionally, the awards were modified such that the measurement and vesting for each tranche will occur on the later of the filing date of the Company’s Annual Report on Form 10-K for the applicable measurement period, or the date the Gartner Non-Memory Semiconductor Revenue Growth benchmark is published. Vesting of these awards occurs approximately 4 months after the end of each measurement period. All other terms of the modified awards including the size of the awards and performance criteria remain the same.

Also during the first nine months of fiscal 2025, we granted additional awards of RSUs with a performance condition to the majority of our employee population. Under the terms of these grants, the RSUs with a performance condition will vest if the Company achieves year-over-year revenue growth targets, and the number of shares vested will scale for achievement of year-over-year revenue growth compared to certain targets, with maximum vesting up to 200% depending on the employee's level. The performance condition will be measured annually after each fiscal year-end for one-half of the grants with the first measurement period beginning in fiscal 2026 and the last measurement period ending at the end of fiscal 2027. Vesting of these awards occurs approximately 4 months after the end of each measurement period.

In the first nine months of fiscal 2025, certain awards with a market condition granted in prior fiscal years vested. During the first quarter of fiscal 2025, the market condition for awards granted to certain executives in the first quarter of fiscal 2022 exceeded the 55th percentile of their TSR condition, and these awards vested at 134%. Also during the first quarter of fiscal 2025, the third tranche of awards granted in fiscal 2021 and 2022 with a performance condition vested. Under the terms of these grants, the RSUs with a performance condition will vest based on the Company generating specified levels of year-over-year revenue growth, which are measured annually for one-fourth of the grants after each fiscal year-end through the end of fiscal 2024, with vesting of each tranche occurring 13 months after the performance condition is met. Vesting of these awards scales for achievement of year-over-year revenue growth compared to certain targets, with maximum vesting up to 200%. The third tranche of these awards vested at the 116.3% level of achievement, based on the Company's year-over-year revenue growth performance as of December 30, 2023. For the fourth tranche of these awards, the Company did not meet the year-over-year revenue growth performance criteria as of December 28, 2024.

For our awards with a market condition or performance condition, we incurred stock compensation expense of approximately $17.9 million and $27.7 million, respectively, in the third quarter and first nine months of fiscal 2025. In the third quarter of fiscal 2024, we incurred stock compensation expense of approximately $4.5 million, partially offset by benefits from forfeitures of approximately $2.9 million due to executive departures. In the first nine months of fiscal 2024, we recorded benefits from forfeitures of approximately $18.0 million due to executive departures, which was partially offset by stock compensation expense of approximately $16.5 million. These amounts are recorded as components of total stock-based compensation.

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

(Shares in thousands) |  | Total |
Balance, December 28, 2024 |  |  | 1,593 |
Granted |  |  | 799 |

Note 10 - Common Stock Repurchase Program

On December 9, 2024, we announced that our Board of Directors had approved a stock repurchase program pursuant to which up to $100 million of outstanding common stock could be repurchased from time to time (the "2025 Repurchase Program"). The duration of the 2025 Repurchase Program is through December 31, 2025.

During the third quarter of fiscal 2025, we repurchased 217,820 shares for $15.0 million, or an average price paid per share of $68.86, under the 2025 Repurchase Program. During the first nine months of fiscal 2025, we have repurchased a total of 1,545,547 shares for $85.9 million, or an average price paid per share of $55.55. All repurchases were open market transactions funded from available working capital. All shares repurchased pursuant to the 2025 Repurchase Program were retired upon settlement. As of September 27, 2025, the remaining portion of the amount authorized for the 2025 Repurchase Program is approximately $14.1 million.

Note 11 - Income Taxes

We are subject to federal and state income tax as well as income tax in the foreign jurisdictions in which we operate. For the third quarter of fiscal 2025, we recorded an income tax benefit of approximately $3.7 million, and for the third quarter of fiscal 2024, we recorded income tax expense of approximately $1.0 million. For the first nine months of fiscal 2025 and 2024, we recorded income tax expense of approximately $1.4 million and $5.2 million, respectively. Income taxes for the three and nine-month periods ended September 27, 2025 and September 28, 2024 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 nine months ended September 27, 2025 and the three and nine months ended September 28, 2024 was driven by stock-based compensation, partially offset by certain discrete items in the period.

The portion of our uncertain tax positions (including penalties and interest) recorded as a liability was $2.6 million and $2.5 million at September 27, 2025 and December 28, 2024, respectively, and is included as a component of Other long-term liabilities on our Consolidated Balance Sheets. The resolution of audits or expiration of statute of limitations could reduce our uncertain tax positions.

On July 4, 2025, the United States enacted tax legislation (the “Tax Act”). The Tax Act includes significant provisions, such as the permanent extension of certain expiring provisions of The 2017 Tax Cuts and Jobs Act, modifications to the international tax framework and the restoration of favorable tax treatment for certain business provisions. The legislation has multiple effective dates with certain provisions effective in 2025. The impacts of provisions effective in 2025 have been incorporated into the income tax provision in the third quarter and first nine months of fiscal 2025 and did not have a material impact on our effective tax rate.

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.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read along with the unaudited consolidated financial statements and notes thereto included in Part I, Item 1 of this Quarterly Report on Form 10-Q, as well as the audited consolidated financial statements and notes thereto and Management’s Discussion and Analysis of Financial Condition and Results of Operations in our 2024 10-K.

Overview

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. Lattice is the low power programmable leader. We solve customer problems across the network, from the Edge to the Cloud, in the Communications, Computing, Industrial, Automotive, and Consumer markets. Our technology, long-standing relationships, and commitment to world-class support helps our customers quickly and easily unleash their innovation to create a smart, secure, and connected world.

Lattice has focused its strategy on delivering programmable logic products and related solutions based on low power, small size, and ease of use. We also serve our customers with intellectual property ("IP") licensing and various other services. Our product development activities include new proprietary products, advanced packaging, existing product enhancements, software development tools, soft IP, and system solutions for high-growth applications such as Edge Artificial Intelligence, wireless and wireline infrastructure, platform security, and factory automation.

Critical Accounting Policies and Use of Estimates

Critical accounting policies are those that are both most important to the portrayal of a company's financial condition and results of operations, and that require management's most difficult, subjective, and complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. There have been no material changes to the items that we disclosed as our critical accounting policies and estimates in Management's Discussion and Analysis of Financial Condition and Results of Operations in our 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, actual results may differ materially from these estimates under different assumptions or conditions. We evaluate our estimates and judgments on an ongoing basis.

Impact of Global Economic Conditions on our Business

We depend in part on stable trade, political, geopolitical, economic, and regulatory environments in the countries where we do business. Increased financial market volatility, inflationary pressure, uncertainty regarding potential increases in tariffs or taxes and impacts from already implemented or announced tariffs, interest rate changes, recessionary concerns, uncertainty in the financial and banking industry, and geopolitical tension and conflicts continue to impact business globally and may impact our operations by causing disruption to our customers, our supply chains, and labor markets. The extent to which increased financial market volatility (including currency market volatility), inflationary pressures, tariffs and trade disruptions, and related uncertainty will impact our business activities will depend on future developments that are highly uncertain and cannot be predicted at this time. Additionally, our business has been impacted by the cyclic correction affecting the broader semiconductor industry, which has seen softened demand across our end markets.

Table of Contents

We are monitoring the rapidly evolving tariff and global trade policies, including tariffs, retaliatory tariffs, and related trade actions announced by the U.S., China, and other countries, and we are working to mitigate potential impacts on our business. The extent and duration of the tariffs and the resulting impact of general economic conditions on our business are uncertain and depend on various factors, such as negotiations between the U.S. and affected countries, the responses of other countries or regions, exemptions that may be granted, availability and cost of alternative sources of supply, the ability to pass additional costs to customers, and demand for our products in affected markets. Changes to U.S. and other countries’ tariff policies, such as the imposition or expansion of tariffs or export bans to specific customers or countries, may reduce or limit demand for, or increase the cost of production of, our products in certain markets, and may adversely impact our supply chain as well as our supply chain strategies, both domestically and internationally, any of which may then have an adverse impact on our results of operations and business. Significant devaluation of the U.S. dollar relative to the currencies of the countries we operate in could increase our Operating Expenses. In addition to existing trade restrictions and tariffs, we are monitoring the U.S. government’s ongoing Section 232 investigation into the national security implications of semiconductor imports. While no new measures have been finalized, the investigation may result in additional tariffs or restrictions that could materially impact our supply chain costs, customer demand, or access to key inputs. We continue to assess potential outcomes and their implications for our operations. See Part I, Item 1A. “Risk Factors” in our 2024 Annual Report on Form 10-K for further discussion on risks related to tariffs.

Revenue by End Market

We sell our products globally to a broad base of customers in three primary end market groups: Communications and Computing, Industrial and Automotive, and Consumer. Across our end markets, our products are increasingly used for AI-related applications, including device usage in AI-optimized servers in data centers, AI-enabled PCs, and AI-enabled robotics and ADAS systems, among others. We also provide IP licensing and services to these end markets.

Within these end markets, there are multiple drivers, including:

• | Communications and computing: data center servers and networking equipment, client computing platforms, and wireless and wireline communications infrastructure deployments,
• | Industrial and automotive: factory automation, robotics, automotive electronics, and industrial Internet of Things ("IoT"),
• | Consumer: smart home, prosumer, and other applications.

The end market data we use is derived from data provided to us by our distributors and end customers. With a diverse base of customers who may manufacture end products spanning multiple end markets, the assignment of revenue to a specific end market requires the use of judgment. We also recognize certain revenue for which end customers and end markets are not yet known. We assign this revenue first to a specific end market using historical and anticipated usage of the specific products, if possible, and allocate the remainder to the end markets based on either historical usage for each product family or industry application data for certain product types.

Revenue from the Communications and Computing end market increased by 21% for the third quarter of fiscal 2025 compared to the third quarter of fiscal 2024 and increased by 18% for the first nine months of fiscal 2025 compared to the first nine months of fiscal 2024 primarily due to stronger demand in data center applications, including general-purpose and AI-specific servers, as well as wireline networking components.

Revenue from the Industrial and Automotive end market decreased by 7% for the third quarter of fiscal 2025 compared to the third quarter of fiscal 2024 and decreased by 20% for the first nine months of fiscal 2025 compared to the first nine months of fiscal 2024 primarily due to softer end market demand and from continued inventory normalization by customers.

While we do not consider AI applications as a distinct end market, we expect AI-related revenue to grow over the next few years based on the growing pipeline of AI-related design wins in a diverse set of applications across all three of our end market segments.

Revenue by Geography

We have a diverse base of customers where distributors represent a significant portion of our total revenue. Our revenue by geographical market is based on the ship-to location of our customers, which can vary from time to time. Revenue in all regions for the third quarter and first nine months of fiscal 2025 compared to the third quarter and first nine months of fiscal 2024 has been impacted by the global macroeconomic environment.

The composition of our revenue by geography is presented in the following table:

Revenue from Customers

We sell our products to independent distributors and directly to customers. 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 the third quarter of fiscal 2025 and 2024, respectively, and 82% and 91% for the first nine months of fiscal 2025 and 2024, respectively.

Gross Margin

The composition of our Gross margin, including as a percentage of revenue, is presented in the following table:

|  | Three Months Ended |  |  | Nine Months Ended |
|  | September 27, |  |  | September 28, |  |  | September 27, |  |  | September 28, |

Gross margin percentage |  |  | 67.9 | % |  |  | 69.0 | % |  |  | 68.1 | % |  |  | 68.5 | %

Gross margin, as a percentage of revenue, decreased 110 basis points in the third quarter of fiscal 2025 compared to the third quarter of fiscal 2024 and decreased by 40 basis points for the first nine months of fiscal 2025 compared to the first nine months of fiscal 2024. Changes in margins were primarily due to higher stock-based compensation associated with market and performance based awards in the current year periods and changes in product mix between the periods presented.

Operating Expenses

Operating expenses increased year-over-year primarily due to higher stock-based compensation in the current year periods; excluding stock-based compensation, operating expenses decreased year-over-year. See "Note 9 – Stock-Based Compensation" for additional details.

Research and Development Expense

The composition of our Research and development expense, including as a percentage of revenue, is presented in the following table:

|  | Three Months Ended |  |  |  |  |  |  | Nine Months Ended |  |  |  |  |

Research and development expense includes headcount-related costs, including cash- and stock-based compensation and benefits, R&D equipment expenses, engineering wafers, licenses, and outside engineering services. These expenditures are for the design of new products, IP cores, processes, packaging, and software solutions. The increase in Research and development expense for the third quarter and first nine months of fiscal 2025 compared to the third quarter and first nine months of fiscal 2024 was primarily due to higher stock-based compensation associated with market-based and performance-based awards in the current year periods coupled with the prior year reduction in stock compensation expense from the forfeiture of equity awards by departing executives. We believe that investing in research and development is important to delivering innovative products to our customers. We expect research and development expense to increase in the future, but to decline as a percentage of revenue.

Selling, General, and Administrative Expense

The composition of our Selling, general, and administrative expense, including as a percentage of revenue, is presented in the following table:

|  | Three Months Ended |  |  |  |  |  |  | Nine Months Ended |  |  |  |  |

Selling, general, and administrative expense includes headcount-related costs, including cash- and stock-based compensation and benefits, related to selling, general, and administrative employees, commissions, depreciation, professional and outside services, trade show, and travel expenses. The increase in Selling, general, and administrative expense for the third quarter and first nine months of fiscal 2025 compared to the third quarter and first nine months of fiscal 2024 was primarily due to higher stock-based compensation associated with market-based and performance-based awards in the current year periods coupled with the prior year reduction in stock compensation expense from the forfeiture of equity awards by departing executives.

The decrease in Amortization of acquired intangible assets for the third quarter and first nine months of fiscal 2025 compared to the third quarter and first nine months of fiscal 2024 was primarily due to the full impairment of the Mirametrix intangible assets in the fourth quarter of fiscal 2024.

Restructuring and Other

The composition of our Restructuring and other activity, including as a percentage of revenue, is presented in the following table:

Percentage of revenue |  |  | 0.8 | % |  |  | 5.4 | % |  |  |  |  |  |  | 0.8 | % |  |  | 2.9 | % |  |  |  |

Restructuring activity is generally comprised of expenses resulting from workforce reductions, cancellation of contracts, and consolidation of our facilities. Details of our restructuring plans and expenses accrued under them are discussed in "Note 6 – Restructuring" to our Consolidated Financial Statements in Part I, Item 1 of this Quarterly Report on Form 10-Q. Restructuring and other costs decreased in the third quarter and first nine months of fiscal 2025 compared to the third quarter and first nine months of fiscal 2024 primarily due to lower costs in the current year periods for severance under the Q3 2024 Plan as compared to higher costs in the prior year periods for severance under both the Q3 2024 and Q3 2023 Plans.

Interest Income (Expense), net

The composition of our Interest income (expense), net, including as a percentage of revenue, is presented in the following table:

Interest income (expense) for the third quarter and first nine months of fiscal 2025 compared to the third quarter and first nine months of fiscal 2024 decreased primarily due to lower interest rates on cash and cash equivalents between the periods.

Other Income (Expense), net

The composition of our Other income (expense), net, including as a percentage of revenue, is presented in the following table:

Our Income tax expense (benefit) is partially offset by federal tax credits. The income tax (benefit) in the third quarter of fiscal 2025 and lower income tax expense for the first nine months of fiscal 2025 was primarily due to tax benefits related to increased federal tax credits.

Adjusted EBITDA

Adjusted EBITDA is a non-GAAP financial measure that we define as net income before net interest income (expense), income tax (benefit) expense, depreciation and amortization, stock-based compensation, and other items that are considered unusual or not representative of underlying trends of our business, including but not limited to: legal expenses outside the ordinary course of business, restructuring, transformation, and other charges, impairments, and other non-recurring charges, if applicable for the periods presented.

We believe that the exclusion of the items eliminated in calculating Adjusted EBITDA provides useful measures for period-to-period comparisons of our business. Accordingly, we believe that Adjusted EBITDA provides useful information in understanding and evaluating our operating results in the same manner as our management and our Board of Directors. Adjusted EBITDA should not be considered in isolation of, or as an alternative to, measures prepared in accordance with GAAP. Other companies, including companies in our industry, may calculate similarly-titled non-GAAP financial measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of Adjusted EBITDA as a tool for comparison.

There are a number of limitations related to the use of Adjusted EBITDA rather than net income, which is the most directly comparable financial measure calculated in accordance with GAAP. Some of the limitations of Adjusted EBITDA include (i) Adjusted EBITDA does not properly reflect capital commitments to be paid in the future, and (ii) although depreciation and amortization are non-cash charges, the underlying assets may need to be replaced and Adjusted EBITDA does not reflect these potential capital expenditures. Our presentation of Adjusted EBITDA should not be construed as an inference that our future results will be unaffected by these expenses or any unusual or non-recurring items, as in the future we may incur expenses similar to the adjustments in this presentation. Evaluation of our performance should consider Adjusted EBITDA alongside other financial performance measures, including our net income and other GAAP results.

A reconciliation of Net income to Adjusted EBITDA, including as a percentage of revenue, is presented in the following table:

Table of Contents

Adjusted EBITDA increased for the third quarter of fiscal 2025 compared to the third quarter of fiscal 2024 primarily due to higher adjusted gross margin and lower adjusted operating expenses. The decrease in Adjusted EBITDA for the first nine months of fiscal 2025 compared to the first nine months of fiscal 2024 was primarily due to lower adjusted gross margin, partially offset by lower adjusted operating expenses.

Liquidity and Capital Resources

The following sections discuss material changes in our financial condition from the end of fiscal 2024, including the effects of changes in our Consolidated Balance Sheets, and the effects of our credit arrangements and contractual obligations on our liquidity and capital resources. There continues to be uncertainty around the extent of market volatility, the impact of tariffs, inflationary pressures, interest rate changes, recessionary concerns, uncertainty in the financial and banking industry, and geopolitical tension, which may impact our liquidity and working capital needs in future periods.

We have historically financed our operating and capital resource requirements through cash flows from operations and from the issuance of long-term debt to fund acquisitions. Cash provided by or used in operating activities will fluctuate from period to period due to fluctuations in operating results, the timing and collection of accounts receivable, and required inventory levels, among other things.

We believe that our financial resources, including current cash and cash equivalents, cash flow from operating activities, and our credit facilities, will be sufficient to meet our liquidity and working capital needs through at least the next 12 months. On September 1, 2022, we entered into our 2022 Credit Agreement, as described in "Note 5 – Long-Term Debt" under Part I, Item 1 of this report. As of September 27, 2025, we did not have significant long-term commitments for capital expenditures. For further information on our cash commitments for operating lease liabilities, see "Note 7 – Leases" under Part I, Item 1 of this report.

In the future, we may continue to consider acquisition opportunities to further extend our product or technology portfolios and further expand our product offerings. In connection with funding capital expenditures, acquisitions, securing additional wafer supply, increasing our working capital, or other purposes, we may seek to obtain equity or additional debt financing. We may also seek to obtain equity or additional debt financing if we experience downturns or cyclical fluctuations in our business that are more severe or longer than we anticipated when determining our current working capital needs.

Cash and cash equivalents

(In thousands) |  | September 27, 2025 |  |  | December 28, 2024 |  |  | $ Change |  |  | % Change |
Cash and cash equivalents |  | $ | 117,910 |  |  | $ | 136,291 |  |  | $ | (18,381 | ) |  |  | (13.5 | )%

As of September 27, 2025, we had Cash and cash equivalents of $117.9 million, of which approximately $48.0 million was held by our foreign subsidiaries. We manage our global cash requirements considering, among other things, (i) available funds among our subsidiaries through which we conduct business, (ii) the geographic location of our liquidity needs, and (iii) the cost to access international cash balances. The repatriation of non-US earnings may require us to withhold and pay foreign income tax on dividends. This should not result in our recording significant additional tax expense as we have accrued expense based on current withholding rates. As of September 27, 2025, we could access all cash held by our foreign subsidiaries without incurring significant additional expense.

The net decrease in Cash and cash equivalents of $18.4 million between December 28, 2024 and September 27, 2025 was primarily driven by cash flows from the following activities:

Operating activities — Cash provided by operating activities results from net income adjusted for certain non-cash items and changes in assets and liabilities. Cash provided by operating activities for the first nine months of fiscal 2025 was $117.5 million compared to $95.5

million for the first nine months of fiscal 2024. This increase of $22.0 million was primarily driven by $17.9 million of net changes in working capital coupled with $4.1 million more cash provided by net income adjusted for non-cash items.

Investing activities — Investing cash flows consist primarily of transactions related to capital expenditures and payments for software and intellectual property licenses. Net cash used by investing activities in the first nine months of fiscal 2025 was $41.1 million compared to $27.7 million in the first nine months of fiscal 2024.

Financing activities — Financing cash flows consist primarily of repurchases of common stock, tax payments related to the net share settlement of restricted stock units, and proceeds from the exercise of options to acquire common stock. Net cash used by financing activities in the first nine months of fiscal 2025 was $95.3 million compared to $71.6 million in the first nine months of fiscal 2024. This $23.7 million increase was due to the following activities. During the first nine months of fiscal 2025, we repurchased approximately 1.5 million shares of common stock for $85.9 million compared to the first nine months of fiscal 2024, where we repurchased approximately 0.8 million shares of common stock for $47.0 million. Payments for tax withholdings on vesting of RSUs partially offset by purchases under the employee stock purchase plan used net cash flows of $9.4 million in the first nine months of fiscal 2025, a decrease of approximately $15.2 million from the net $24.6 million used in the first nine months of fiscal 2024.

Accounts receivable, net as of September 27, 2025 increased by approximately $14.4 million, or 18%, compared to December 28, 2024. This increase was due to order scheduling through the quarter. We calculate Days sales outstanding on the basis of a 365-day year as Accounts receivable, net at the end of the quarter divided by sales during the quarter annualized and then multiplied by 365.

Inventories

Days of inventory on hand |  |  | 193 |  |  |  | 207 |  |  |  | (14 | ) |  |  |  |

Inventories as of September 27, 2025 decreased by approximately $12.7 million, or 12%, compared to December 28, 2024 primarily as a result of our continued optimization of inventory to efficient levels for the business. Days of inventory on hand increased over the period due to lower cost of revenue.

The Days of inventory on hand ratio compares the inventory balance at the end of a quarter to the cost of revenue in that quarter. We calculate Days of inventory on hand on the basis of a 365-day year as Inventories at the end of the quarter divided by Cost of revenue during the quarter annualized and then multiplied by 365.

Credit Arrangements

As of September 27, 2025, we had no used or unused credit arrangements beyond the secured revolving loan facility described in the 2022 Credit Agreement. The details of this arrangement are described in "Note 5 – Long-Term Debt" in the Notes to Consolidated Financial Statements of this Quarterly Report on Form 10-Q.

Share Repurchase Program

See Part II, Item 2, “Unregistered Sales of Equity Securities and Use of Proceeds,” of this Quarterly Report on Form 10-Q for more information about the share repurchase program.

New Accounting Pronouncements

The information contained under the heading "New Accounting Pronouncements" in Note 1 – Basis of Presentation to our Consolidated Financial Statements in Part I, Item 1 of this report is incorporated by reference into this Part I, Item 2.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. Our market risk exposure is primarily a result of fluctuations in foreign currency exchange rates and interest rates. We assess these risks on a regular basis and have established policies that are designed to protect against the adverse effects of these and other potential exposures. There have been no material changes to either the foreign currency exchange rate risk or interest rate risk previously disclosed in Part II, Item 7A, "Quantitative and Qualitative Disclosures About Market Risk," of our 2024 10-K.

ITEM 4. CONTROLS AND PROCEDURES

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

In connection with the filing of this Quarterly Report on Form 10-Q, our management, including our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this report. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls were effective as of the end of the period covered by this report.

Changes in Internal Control over Financial Reporting

There were no changes in our internal controls over financial reporting (as defined in Rules 13a-15(f) under the Exchange Act) that occurred during the third quarter of fiscal 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

We do not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

In addition to the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the risk factors associated with our business previously described in Part I, Item 1A, “Risk Factors,” in our 2024 10-K. There have been no material changes in the risk factors included in our 2024 10-K, and this report should be read in conjunction with the risk factors set forth in our 2024 10-K. These risk factors are not the only risks facing our company. Additional risks and uncertainties not presently known to us or that we may currently deem to be immaterial could materially adversely affect our business, financial condition, or operating results, including those related to adverse macroeconomic conditions, such as tariffs and trade disruptions, rising inflation, and labor shortages, which may affect demand for our products or increase our product or labor costs, negatively impacting our revenues, gross margins, and overall financial results. If any of these risks occur, our business, financial condition, operating results, and cash flows could be materially adversely affected, and the trading price of our common stock could decline. These factors, together with all of the other information in this Quarterly Report on Form 10-Q, including our unaudited condensed consolidated financial statements and the accompanying notes included elsewhere in this Quarterly Report on Form 10-Q, should be carefully considered before making an investment decision relating to our common stock.
