~50% Expected Q2 2026 YoY Revenue Growth Fueled by Increased Visibility into Multi-Year Expansion Cycle

AMI Acquisition Creates Industry's Most Complete Platform for Secure Management and Control

Lattice Semiconductor Corporation (NASDAQ:LSCC), the low power programmable leader, announced financial results today for the fiscal first quarter ended April 4, 2026.

Revenue for the first quarter of 2026 was $170.9 million, with GAAP gross margin of 68.8%, and GAAP net income of $0.16 per diluted share. On a non-GAAP basis, gross margin was 70.0%, with net income per diluted share of $0.41. GAAP net income and GAAP net income margin for the first quarter of 2026 were $21.8 million and 12.8%, respectively, with adjusted EBITDA of $67.8 million, which is a 39.6% adjusted EBITDA margin for the first quarter of 2026. GAAP net cash flow from operating activities for the first quarter of 2026 was $50.3 million, which is a GAAP operating cash flow margin of 29.4%, and non-GAAP free cash flow and free cash flow margin of $39.7 million and 23.2%, respectively.

Ford Tamer, Chief Executive Officer, said, "We delivered record first quarter revenue growth, led by increased demand across all of our end markets. As we had committed, we grew non-GAAP earnings faster than revenue, achieving 86% year over year EPS growth. Our Compute and Communications business achieved record revenue, while our Industrial and Embedded business growth exceeded 20% quarter over quarter. When taken together with our strong backlog, continued design win momentum and leadership in small and mid-range FPGAs, we believe we are in the early stages of a multi-year growth cycle and are well positioned to deliver sustained, above-market growth in 2026 and beyond."

Lorenzo Flores, Chief Financial Officer, said, "We continue to drive increased profitability, with our model demonstrating strong operating leverage as revenue growth translates to bottom-line expansion. We remain focused on scaling the business efficiently while investing to extend our leadership in small and mid-range FPGAs and expand our companion chip opportunity. Lattice is positioned to drive continued short and long-term revenue growth, strength in margin, and increased free cash flow."

* 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."

First Quarter 2026 Highlights:

	•	Record New Product Revenue Growth: Revenue from our new products continues to expand, led by AI-related server demand.
	•	NVIDIA GTC 2026: Joined the NVIDIA Halos AI Systems Inspection Lab ecosystem, the first ANSI National Accreditation Board (ANAB) accredited inspection lab for AI-driven physical systems. Lattice will engage with NVIDIA and other ecosystem members to build Halos-certified Holoscan Sensor Bridge-based designs for physical AI and to help shape best practices as the industry evolves.
	•	Texas Instruments (TI) Edge AI Collaboration: Announced a collaboration with TI to simplify sensor integration and to scale real-time edge AI systems, leveraging TI sensing technology and the Lattice + NVIDIA Holoscan Sensor Bridge solution to enable advanced robotics and industrial applications.
	•	Recognized for Workplace Excellence, Product Leadership and Innovation: Lattice won Embedded Computing Design's prestigious Best in Show award; was named to USA TODAY's Top Workplaces in 2026; won multiple 2026 Globee Cybersecurity Awards; was named a multi-award winner at the 2026 Cybersecurity Excellence Awards; won two Global InfoSec awards from Cyber Defense Magazine (CDM) at the 2026 RSA Conference, and was named a 2026 Environment + Energy Leader Award winner.

Business Outlook - Second Quarter of 2026:

	•	Revenue for the second quarter of 2026 is expected to be between $175 million and $195 million.
	•	Gross margin percentage for the second quarter of 2026 is expected to be 70% plus or minus 1% on a non-GAAP basis.
	•	Total operating expenses for the second quarter of 2026 are expected to be between $64 million and $67 million on a non-GAAP basis.
	•	Income tax rate for the second quarter of 2026 is expected to be between 4% and 6% on a non-GAAP basis.
	•	Net income for the second quarter of 2026 is expected to be between $0.42 and $0.46 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 second quarter of 2026, 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 charges. 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 second quarter 2026 quarterly guidance.

Lattice announces signing of definitive agreement to acquire firmware leader, AMI

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 growth including AI and datacenter-related growth; our belief that we are in the early stages of a multi-year growth cycle and are well positioned to deliver sustained, above-market growth; statements about operating leverage and margin expansion; statements about design win momentum, backlog strength, and our companion chip opportunity; our expectations regarding the pending acquisition of AMI, including expected benefits, integration, and expected accretive impact on gross margin, free cash flow, and EPS; the statements under the heading "Business Outlook - Second Quarter of 2026." 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 including fluctuating customer and distributor purchasing patterns, inventory levels, and order timing; pricing and inflationary pressures; competitive actions; international trade disputes and sanctions; the impact of tariffs, trade restrictions, export controls, license requirements or similar actions on us or 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; our expectations regarding our pending acquisition of AMI, including the risks related to the satisfaction of closing conditions, regulatory approvals, the ability to successfully integrate the acquired business, retention of key personnel, realization of expected synergies and benefits, and the expected accretive impact on gross margin, free cash flow, and EPS; and other significant risks and uncertainties that are beyond our ability to predict or control. Actual gross margin percentage, operating expenses, income tax rate, and net income on a per share basis 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 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; transformation activities; legal expense outside the ordinary course of business; amortization of acquired intangible assets; restructuring plan and other charges; impairment charges; 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.

Lattice Semiconductor today announced that it has updated its disaggregated end market reporting to better reflect how the Company views its business. Effective beginning Q1 2026, Lattice Semiconductor will disaggregate revenue by end market into (i) Compute and Communications and (ii) Industrial and Embedded. Compute and Communications reflects a reordering of the Company's prior Communications and Computing end market, while Industrial and Embedded combines the Company's previously reported Industrial and Automotive, and Consumer end markets. This change represents a presentation-only update and has no impact on the Company's consolidated financial results. Prior period end market information will be recast to conform to the new presentation to facilitate comparability.

Fiscal year 2025 quarterly revenue disaggregated by end market is shown below:
