Lattice Semiconductor Reports Record Communications & Computing Revenue in Third Quarter 2025

Guides to 4Q25 Revenue Growth of 22% Year Over Year

Lattice Semiconductor Corporation (NASDAQ:LSCC), the low power programmable leader, announced financial results today for the fiscal third quarter ended September 27, 2025.

Revenue for the third quarter of 2025 was $133.3 million, with GAAP gross margin of 67.9%, and GAAP net income of $0.02 per diluted share. On a non-GAAP basis, gross margin was 69.5%, with net income per diluted share of $0.28. GAAP net income and GAAP net income margin for the third quarter of 2025 were $2.8 million and 2.1%, respectively, with adjusted EBITDA of $47.4 million, which is a 35.6% adjusted EBITDA margin for the third quarter of 2025. GAAP net cash flow from operating activities for the third quarter of 2025 was $47.0 million, which is a GAAP operating cash flow margin of 35.3%, and free cash flow and free cash flow margin of $34.0 million and 25.5%, respectively.

Ford Tamer, Chief Executive Officer, said, "We delivered a strong quarter, with broad-based growth across our end markets, and grew non-GAAP earnings 17% quarter over quarter. Our Communications and Computing business achieved record revenue, and we are expecting continued growth into the fourth quarter and beyond. We continue to drive operating leverage and expand profitability, with significant revenue and non-GAAP EPS growth of 13% and 29%, respectively, expected in the second half of 2025 compared to the first half of 2025."

Lorenzo Flores, Chief Financial Officer, said, "We grew revenue, non-GAAP gross margin, and non-GAAP profitability both sequentially and on a year-on-year basis. Our Industrial and Automotive markets continue to recover, with inventory levels expected to be normalized by the end of the year, as discussed at the start of 2025. We remain focused on executing our strategy, including making investments to strengthen our leadership in Small and Mid-Range FPGAs."

* GAAP represents U.S. Generally Accepted Accounting Principles. Non-GAAP represents GAAP excluding the impact of certain activities which the Company's management excludes in analyzing the Company's operating results and in understanding trends in the Company's earnings. Additional information relating to these measures is included below in "Non-GAAP Financial Measures." For a reconciliation of GAAP to non-GAAP results, see accompanying tables "Reconciliation of U.S. GAAP to Non-GAAP Financial Measures."

Recent Highlights:

• Industry's First PQC-Ready FPGA: Launched the Lattice MachXO5™-NX TDQ family delivers unmatched security, reliability, and flexibility for Computing, Communications, Industrial, and Automotive applications as the threat of quantum-enabled cyberattacks rises. This is the industry's first secure control FPGAs with full Commercial National Security Algorithm (CNSA) 2.0-compliant post-quantum cryptography (PQC) support.
• Growing Business Momentum at OCP Global Summit: Recent AI announcements generated higher interest in Lattice's low-power solutions at the OCP Global Summit, and accelerated existing momentum of Lattice's datacenter solutions for hyperscalers, neo-Cloud, enterprise, server and communications OEMs, and ODM partners.
• Disciplined Capital Allocation: Lattice repurchased common stock valued at $85 million through the first nine months of 2025.
• Top Workplace: Lattice was recognized as a 2025 Top Workplace in Oregon and Southwest Washington, and a Top Workplace for Employee Appreciation and Employee Wellbeing.

Business Outlook - Fourth Quarter of 2025:

• Revenue for the fourth quarter of 2025 is expected to be between $138 million and $148 million.
• Gross margin percentage for the fourth quarter of 2025 is expected to be 69.5% plus or minus 1% on a non-GAAP basis.
• Total operating expenses for the fourth quarter of 2025 are expected to be between $54 million and $55 million on a non-GAAP basis.
• Income tax rate for the fourth quarter of 2025 is expected to be between 3% and 5% on a non-GAAP basis.
• Net income for the fourth quarter of 2025 is expected to be between $0.30 and $0.34 per share on a non-GAAP basis.

Non-GAAP Financial Measures: In addition to financial measures prepared in accordance with generally accepted accounting principles (GAAP), this earnings release makes reference to non-GAAP financial measures. With respect to the outlook for the fourth quarter of 2025, certain items that affect reconciliation of non-GAAP financial measures for non-GAAP gross margin percentage, non-GAAP total operating expenses, non-GAAP income tax rate, and non-GAAP net income are not available on a forward-looking basis because such items cannot be reasonably calculated without unreasonable efforts due to the unpredictability of the amounts and timing of events affecting the items we exclude from non-GAAP financial measures, including certain large and/or unpredictable charges such as stock-based compensation expense; performance-based equity expense; legal expense outside the ordinary course of business; restructuring; and impairment. Consequently, the Company is unable to calculate the most directly comparable GAAP measure to non-GAAP gross margin percentage, non-GAAP total operating expenses, non-GAAP income tax rate, and non-GAAP net income for the Company's fourth quarter 2025 quarterly guidance.

Forward-Looking Statements Notice:

This press release contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 and made pursuant to the safe harbor provisions of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These statements involve estimates, assumptions, risks and uncertainties. Any statements about our expectations, beliefs, plans, objectives, assumptions or future events or performance are neither historical facts nor assurances of future performance and may be forward-looking. Such forward-looking statements include, but are not limited to, statements relating to our revenue and EPS growth, future financial performance and related drivers, our expectations related to market recovery and improvement; and the statements under the heading "Business Outlook - Fourth Quarter of 2025." Other forward-looking statements may be indicated by words such as "will," "could," "should," "would," "may," "expect," "plan," "project," "anticipate," "intend," "forecast," "future," "believe," "estimate," "predict," "propose," "potential," "continue" or the negative of these terms or other comparable terminology.

Estimates of future revenue and other financial and operational outcomes are inherently uncertain due to factors such as global economic conditions which may affect customer demand, the cyclical nature of the semiconductor industry, pricing and inflationary pressures, competitive actions, international trade disputes and sanctions, the potential impact of global pandemics, the impact of tariffs, license requirements or similar actions on our suppliers 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; and other significant risks and uncertainties that are beyond our ability to predict or control. Actual gross margin percentage and operating expenses could vary from the estimates on the basis of, among other things, changes in revenue levels, changes in product pricing and mix, changes in wafer, assembly, test and other costs, variations in manufacturing yields, the failure to sustain operational improvements, and the actual amount of compensation charges due to stock price changes.

Actual income tax rate and actual net income on a per share basis may differ from our expectations. Actual results may differ materially from our expectations and are subject to risks and uncertainties that relate more broadly to our overall business, including those described in our filings with the Securities and Exchange Commission, including Lattice's most recent Annual Report on Form 10-K, especially those under the captions "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations", all of which are expressly incorporated herein by reference.

Lattice believes these and other risks and uncertainties could cause actual results to differ materially from the forward-looking statements. New risk factors emerge from time to time and it is not possible for the Company to predict all risk factors. You should not rely on forward-looking statements because actual results could differ materially from those expressed in any forward-looking statements. In addition, any forward-looking statement applies only as of the date on which it is made. The Company does not intend to and undertakes no obligation to update or revise any forward-looking statements, whether as a result of events or circumstances after the date hereof or to reflect the occurrence of unanticipated events.

Non-GAAP Financial Measures:

Included within this press release and the accompanying tables and notes are certain non-GAAP financial measures that supplement the Company's consolidated financial information prepared in accordance with U.S. GAAP, including non-GAAP gross margin, gross margin percentage, R&D expense, SG&A expense, operating expenses, income from operations, income tax expense, net income, net income per share – basic, and net income per share – diluted, adjusted EBITDA, adjusted EBITDA margin, free cash flow, and free cash flow margin. The non-GAAP measures presented exclude charges and adjustments primarily related to stock-based compensation and related payroll tax effects; accruals related to the portion of our annual incentive plan that we intend to settle in shares of our common stock; legal expense outside the ordinary course of business; amortization of acquired intangible assets; restructuring plans, transformation activities, and other charges; impairments; and the estimated tax effect of these items, non-cash changes in net deferred income taxes, change in tax law and other tax adjustments; and depreciation and other amortization. These charges and adjustments are a result of periodic or non-core operating activities of the Company. The Company describes these non-GAAP financial measures and reconciles them to the most directly comparable GAAP measures in the tables and notes attached to this press release.

The Company's management believes that these non-GAAP financial measures provide an additional and useful way of viewing aspects of our performance that, when viewed in conjunction with our GAAP results, provide a more comprehensive understanding of the various factors and trends affecting our ongoing financial performance and operating results than GAAP measures alone. Management also uses these non-GAAP measures for strategic and business decision-making, internal budgeting, forecasting, and resource allocation processes and believes that investors should have access to similar data. The non-GAAP financial information used by the Company may differ from that used by other companies. These non-GAAP measures are included solely for informational and comparative purposes and are not meant as a substitute for GAAP and should be considered together with the consolidated financial information located in the tables attached to this press release.
