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 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, actual results may differ materially from these estimates under different assumptions or conditions. We evaluate our estimates and judgments on an ongoing basis. Results of Operations Key elements of our Consolidated Statements of Operations, including as a percentage of revenue, are presented in the following table: Three Months Ended Six Months Ended July 4, June 28, July 4, June 28, (In thousands) 2026 2025 2026 2025 Revenue $ 201,079 100.0 % $ 123,971 100.0 % $ 371,976 100.0 % $ 244,121 100.0 % Gross margin 141,332 70.3 84,751 68.4 258,964 69.6 166,479 68.2 Research and development 64,231 31.9 43,530 35.1 115,067 30.9 84,917 34.8 Selling, general and, administrative 50,278 25.0 34,811 28.1 90,383 24.3 67,937 27.8 Amortization of acquired intangible assets 19 0.0 13 0.0 39 0.0 13 0.0 Restructuring and other 22 0.0 1,691 1.4 625 0.2 1,932 0.8 Acquisition related 4,429 2.2 — — 4,429 1.2 — — Income from operations $ 22,353 11.1 % $ 4,706 3.8 % $ 48,421 13.0 % $ 11,680 4.8 % - 19 - Table of Contents Revenue by End Market During the first quarter of 2026, we aligned our end market structure to our larger strategic market focus areas. We sell our products globally to a broad base of customers in two primary end market groups: Compute and Communications, and Industrial and Embedded. 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: • Compute and Communications: data center servers, storage, and networking equipment, client computing platforms, and wireless and wireline communications infrastructure deployments, • Industrial and Embedded: factory automation, robotics, automotive electronics, and industrial Internet of Things ("IoT"), 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. The following are examples of end market applications for the periods presented: Compute and Communications Industrial and Embedded Data Networking Security and Surveillance Server Computing Machine Vision Client Computing Industrial Automation Data Storage Robotics Cloud Automotive Hyperscalers Drones Wireless Factory Automation Wireline Cameras Displays / Televisions Home Theater / Sound Systems Wearables The composition of our revenue by end market is presented in the following table: Three Months Ended Six Months Ended July 4, June 28, July 4, June 28, (In thousands) 2026 2025 2026 2025 Compute and Communications $ 125,944 62.6 % $ 68,664 55.4 % $ 232,576 62.5 % $ 126,098 51.6 % Industrial and Embedded 75,135 37.4 55,307 44.6 139,400 37.5 118,023 48.4 Total revenue $ 201,079 100.0 % $ 123,971 100.0 % $ 371,976 100.0 % $ 244,121 100.0 % Note: During the first quarter of 2026, we began disaggregating our revenue by Compute and Communications, and Industrial and Embedded. Prior periods have been reclassified to match current period presentation. Revenue from the Compute and Communications end market increased by 83% for the second quarter of fiscal 2026 compared to the second quarter of fiscal 2025 and increased by 84% for the first six months of fiscal 2026 compared to the first six months of fiscal 2025 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 Embedded end market increased by 36% for the second quarter of fiscal 2026 compared to the second quarter of fiscal 2025 and increased by 18% for the first six months of fiscal 2026 compared to the first six months of fiscal 2025 primarily due to recovering end market demand particularly from industrial and aerospace customers. AI applications are pervasive across our end markets, so 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 both of our end market groups. - 20 - Table of Contents 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. For the second quarter of fiscal 2026 compared to the second quarter of fiscal 2025 and for the first six months of fiscal 2026 compared to the first six months of fiscal 2025, revenue from Asia increased by 92% and 82%, respectively, primarily due to hyperscaler demand, while revenue from the Americas decreased by 14% and 26%, respectively, primarily due to the non-recurrence of certain one-time sales in the prior year period, and revenue from Europe increased by 32% and 44%, respectively, primarily due to broad market recovery in this region. The composition of our revenue by geography is presented in the following table: Three Months Ended Six Months Ended July 4, June 28, July 4, June 28, (In thousands) 2026 2025 2026 2025 Asia $ 159,359 79.2 % $ 82,974 66.9 % $ 291,936 78.4 % $ 160,715 65.8 % Americas 23,106 11.5 26,883 21.7 41,898 11.3 56,880 23.3 Europe 18,614 9.3 14,114 11.4 38,142 10.3 26,526 10.9 Total revenue $ 201,079 100.0 % $ 123,971 100.0 % $ 371,976 100.0 % $ 244,121 100.0 % 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 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. Gross Margin The composition of our Gross margin, including as a percentage of revenue, is presented in the following table: Three Months Ended Six Months Ended July 4, June 28, July 4, June 28, (In thousands) 2026 2025 2026 2025 Gross margin $ 141,332 $ 84,751 $ 258,964 $ 166,479 Gross margin percentage 70.3 % 68.4 % 69.6 % 68.2 % Gross margin, as a percentage of revenue, increased 190 basis points in the second quarter of fiscal 2026 compared to the second quarter of fiscal 2025 and increased by 140 basis points for the first six months of fiscal 2026 compared to the first six months of fiscal 2025. Higher margins resulted primarily from changes in product mix and volume between the periods, partially offset by higher stock-based compensation expense associated with market and performance-based awards in the current year. Operating Expenses 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 Six Months Ended July 4, June 28, July 4, June 28, (In thousands) 2026 2025 % change 2026 2025 % change Research and development $ 64,231 $ 43,530 47.6 % $ 115,067 $ 84,917 35.5 % Percentage of revenue 31.9 % 35.1 % 30.9 % 34.8 % 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 second quarter and first six months of fiscal 2026 compared to the second quarter and first six months of fiscal 2025 was primarily due to higher stock-based and cash-based compensation expense, along with higher depreciation and amortization on semiconductor equipment and licensed software tools, and higher expenses for mask sets and prototypes. 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. - 21 - Table of Contents 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 Six Months Ended July 4, June 28, July 4, June 28, (In thousands) 2026 2025 % change 2026 2025 % change Selling, general, and administrative $ 50,278 $ 34,811 44.4 % $ 90,383 $ 67,937 33.0 % Percentage of revenue 25.0 % 28.1 % 24.3 % 27.8 % 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 second quarter and first six months of fiscal 2026 compared to the second quarter and first six months of fiscal 2025 was primarily due to higher stock-based and cash-based compensation expense. We expect selling, general, and administrative expense to increase in the future, but to decline as a percentage of revenue. Amortization of Acquired Intangible Assets The composition of our Amortization of acquired intangible assets, including as a percentage of revenue, is presented in the following table: Three Months Ended Six Months Ended July 4, June 28, July 4, June 28, (In thousands) 2026 2025 % change 2026 2025 % change Amortization of acquired intangible assets $ 19 $ 13 46.2 % $ 39 $ 13 100+% Percentage of revenue 0.0 % 0.0 % 0.0 % 0.0 % The increase in Amortization of acquired intangible assets for the second quarter and first six months of fiscal 2026 compared to the second quarter and first six months of fiscal 2025 was due to the purchase of intellectual property assets in the second quarter of fiscal 2025. Restructuring and Other The composition of our Restructuring and other activity, including as a percentage of revenue, is presented in the following table: Three Months Ended Six Months Ended July 4, June 28, July 4, June 28, (In thousands) 2026 2025 % change 2026 2025 % change Restructuring and other $ 22 $ 1,691 (98.7 )% $ 625 $ 1,932 (67.7 )% Percentage of revenue 0.0 % 1.4 % 0.2 % 0.8 % Restructuring and other 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 second quarter and first six months of fiscal 2026 compared to the second quarter and first six months of fiscal 2025 as we completed the actions planned under the Q3 2024 Plan. Acquisition Related The composition of our Acquisition related activity, including as a percentage of revenue, is presented in the following table: Three Months Ended Six Months Ended July 4, June 28, July 4, June 28, (In thousands) 2026 2025 % change 2026 2025 % change Acquisition related $ 4,429 $ — — % $ 4,429 $ — — % Percentage of revenue 2.2 % — % 1.2 % — % Acquisition related activity includes professional fees and other expenses directly related to acquisitions. For fiscal 2026, Acquisition related expenses were entirely attributable to our acquisition of AMI which we completed in July 2026 and were comprised of professional fees for legal, accounting, and outside services, and for acquisition related travel costs. - 22 - Table of Contents Interest Income (Expense), net The composition of our Interest income (expense), net, including as a percentage of revenue, is presented in the following table: Three Months Ended Six Months Ended July 4, June 28, July 4, June 28, (In thousands) 2026 2025 % change 2026 2025 % change Interest income (expense), net $ (88 ) $ 614 (100+)% $ 1,181 $ 1,666 (29.1 )% Percentage of revenue (0.0 )% 0.5 % 0.3 % 0.7 % Changes in Interest income (expense) for the second quarter and first six months of fiscal 2026 compared to the second quarter and first six months of fiscal 2025 were primarily due to amortization of debt costs related to the bridge facility in the current year periods as discussed in "Note 5 – Long-Term Debt" to our Consolidated Financial Statements in Part I, Item 1 of this Quarterly Report on Form 10-Q. Other Income (Expense), net The composition of our Other income (expense), net, including as a percentage of revenue, is presented in the following table: Three Months Ended Six Months Ended July 4, June 28, July 4, June 28, (In thousands) 2026 2025 % change 2026 2025 % change Other income (expense), net $ (5,048 ) $ (238 ) 100+% $ (5,119 ) $ (283 ) 100+% Percentage of revenue (2.5 )% (0.2 )% (1.4 )% (0.1 )% Changes in Other income (expense) for the second quarter and first six months of fiscal 2026 compared to the second quarter and first six months of 2025 were primarily due to the write-off of $4.7 million of unamortized debt costs related to the bridge facility and $0.2 million of unamortized debt cost associated with the 2022 Credit Agreement upon the re-financing of our long-term debt. Income Tax Expense The composition of our Income tax expense is presented in the following table: Three Months Ended Six Months Ended July 4, June 28, July 4, June 28, (In thousands) 2026 2025 % change 2026 2025 % change Income tax expense (benefit) $ (2,142 ) $ 2,169 (100+)% $ 3,307 $ 5,128 (35.5 )% The lower income tax expense for the second quarter and first six months of fiscal 2026 compared to the second quarter and first six months of fiscal 2025 was primarily due to the impact of stock-based compensation combined with federal tax credits, partially offset by increased worldwide income. Adjusted EBITDA Adjusted EBITDA is a non-GAAP financial measure that we define as net income before net interest income (expense), income tax 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, transformation charges incurred in connection with our multi‑year strategic initiative to realign our organizational structure and modernize our technology platforms, restructuring, and other 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. - 23 - Table of Contents 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: Three Months Ended Six Months Ended July 4, June 28, July 4, June 28, (In thousands) 2026 2025 2026 2025 GAAP Net income $ 19,359 $ 2,913 $ 41,176 $ 7,935 GAAP Net income margin 9.6 % 2.3 % 11.1 % 3.3 % Interest (income) expense, net 88 (614 ) (1,181 ) (1,666 ) Income tax expense (benefit) (2,142 ) 2,169 3,307 5,128 Amortization of acquired intangible assets 19 13 39 13 Depreciation and other amortization 9,414 8,380 18,523 16,966 Stock-based compensation (1) 44,852 24,141 73,343 44,697 Incentive compensation to be settled in equity (2) 5,427 1,274 8,860 2,802 Transformation charges — 1,541 — 2,553 Legal expenses (3) — 568 — 1,101 Restructuring and other 22 1,841 725 2,777 Acquisition related 4,429 — 4,429 — Write-off unamortized debt costs 4,898 — 4,898 — Adjusted EBITDA $ 86,366 $ 42,226 $ 154,119 $ 82,306 Adjusted EBITDA margin 43.0 % 34.1 % 41.4 % 33.7 % (1) Includes stock-based compensation and related payroll tax expenses. (2) Includes accruals for the portion of our annual Corporate Incentive Plan that we intend to settle in equity and related payroll tax expenses. (3) Includes legal expenses outside the ordinary course of business, including those incurred defending against claims described in our 2025 10-K. Adjusted EBITDA increased for the second quarter and first six months of fiscal 2026 compared to the second quarter and first six months of fiscal 2025 primarily as a result of higher revenue, partially offset by higher headcount-related expenses and higher expenses for mask sets and prototypes. Liquidity and Capital Resources The following sections discuss material changes in our financial condition from the end of fiscal 2025, 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 June 30, 2026, we entered into our 2026 Credit Agreement, as described in "Note 5 – Long-Term Debt" under Part I, Item 1 of this report. As of July 4, 2026, 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. - 24 - Table of Contents Cash and cash equivalents (In thousands) July 4, 2026 January 3, 2026 $ Change % Change Cash and cash equivalents $ 173,305 $ 133,886 $ 39,419 29.4 % As of July 4, 2026, we had Cash and cash equivalents of $173.3 million, of which $46.5 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 July 4, 2026, we could access all cash held by our foreign subsidiaries without incurring significant additional expense. The net increase in Cash and cash equivalents of $39.4 million between January 3, 2026 and July 4, 2026 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 six months of fiscal 2026 was $138.6 million compared to $70.4 million for the first six months of fiscal 2025. This increase of $68.2 million was primarily driven by $67.6 million more cash provided by net income adjusted for non-cash items, coupled with $0.6 million of net changes in working capital. Investing activities — Investing cash flows consist primarily of transactions related to capital expenditures, payments for software and intellectual property licenses, and purchases of other investments. Net cash used by investing activities in the first six months of fiscal 2026 was $42.7 million compared to $23.6 million in the first six months of fiscal 2025. Financing activities — Financing cash flows consist primarily of repurchases of common stock, tax payments related to the net share settlement of restricted stock units, proceeds from the acquisition of common stock under our employee stock purchase plan, and activity related to our long-term debt. Net cash used by financing activities was $56.5 million in the first six months of fiscal 2026 compared to $76.6 million in the first six months of fiscal 2025. This decrease of $20.1 million was due to the following activities: (i) during the first six months of fiscal 2026, we repurchased 0.2 million shares of common stock for $15.0 million, a decrease of $55.9 million compared to the first six months of fiscal 2025, where we repurchased 1.3 million shares of common stock for $70.9 million, (ii) payments for tax withholdings on vesting of RSUs partially offset by purchases under the employee stock purchase plan used net cash flows of $29.7 million in the first six months of fiscal 2026, an increase of $24.0 million from the net $5.7 million used in the first six months of fiscal 2025, and (iii) during the first six months of fiscal 2026, we paid $11.7 million in issuance costs related to new long-term debt under the bridge facility and the 2026 Credit Agreement. Accounts receivable, net (In thousands) July 4, 2026 January 3, 2026 $ Change % Change Accounts receivable, net $ 120,024 $ 102,277 $ 17,747 17.4 % Days sales outstanding 54 64 (10 ) Accounts receivable, net as of July 4, 2026 increased by $17.7 million, or 17%, compared to January 3, 2026. This increase was due to increased revenue and 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 (In thousands) July 4, 2026 January 3, 2026 $ Change % Change Inventories $ 100,501 $ 89,202 $ 11,299 12.7 % Days of inventory on hand 153 178 (25 ) Inventories as of July 4, 2026 increased by $11.3 million, or 13%, compared to January 3, 2026 as we build inventory to meet continued demand growth. 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. - 25 - Table of Contents Credit Arrangements As of July 4, 2026, we had no used or unused credit arrangements beyond the facilities described in the 2026 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.
