2019 Highlights

• Improved Financial Performance and Increased Profitability: Increased net income per diluted share on a GAAP basis to $0.32 in the full year 2019 from a loss of $0.21 in the full year 2018, or $0.59 and $0.33, respectively, on a non-GAAP basis, with a 400 basis point improvement in gross margin on a GAAP basis and a 210 basis point improvement on a non-GAAP basis.
• Debt Refinance and De-lever: Total full year 2019 debt payments of $117 million, which reduced the leverage ratio to 1.3 compared to 3.0 at the end of 2018, as defined in the credit agreement. The Company reduced the interest rate by a total of 300 basis points in 2019.
• Nexus™ Next Generation FDSOI Platform and CrossLink-NX™ FPGA Launched: Nexus, Lattice's next generation 28nm FDSOI platform, launched on December 10, 2019, ahead of schedule. Based on FDSOI technology, the Nexus platform delivers up to a 75% reduction in power versus competitors' products. Lattice's CrossLink-NX™, the first FPGA developed on Lattice's Nexus platform, provides the small form factor, reliability, and performance that developers need to create innovative embedded vision and AI solutions for communications, compute, industrial, automotive, and consumer systems.
• Enhanced Radiant™ Software Design Tool: Lattice launched the latest version of its popular software design tool for FPGAs, Lattice Radiant™ 2.0. The updated design tool offers new features that make it faster and easier than ever to develop Lattice FPGA-based designs.
• Launched New MachXO3D™ Platform Security Product: The new platform security product was developed specifically for customers seeking to simplify the implementation of robust, comprehensive and flexible hardware-based security. MachXO3D can protect, detect and recover firmware components from unauthorized firmware access at every stage of a system’s lifecycle, from the point of manufacturing all the way to the system’s end of life. The National Institute of Standards and Technology ("NIST") independently certified that Lattice's MachXO3D is compliant with the U.S. government's standard for cryptographic software.
• Higher Performance, Award-Winning sensAI™ Solutions Stack: Lattice launched major performance and design flow enhancements to its award-winning AI solutions stack. The Lattice sensAI stack provides a comprehensive hardware and software solution for implementing low power, always-on AI functionality in smart devices operating at the Edge. sensAI was awarded the EDN Hot 100 Product Award, Tools & Development Category, the AI Breakthrough Award, Best AI-Based Solution for Engineering, the Electronics Industry Award, and the Internet of Things Product of the Year.

Business Outlook - First Quarter of 2020:

• Revenue for the first quarter of 2020 is expected to be between $96 million and $104 million.
• Gross margin percentage for the first quarter of 2020 is expected to be 59.5% plus or minus 1% on a non-GAAP basis.
• Total operating expenses for the first quarter of 2020 are expected to be between $36 million and $37 million 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 first quarter of 2020, certain items that affect GAAP measurement of financial measures are out of the Company’s control and/or cannot be reasonably predicted. Consequently, the Company is unable to provide a reasonable estimate of GAAP measurement for guidance or a corresponding reconciliation to GAAP for the quarter. Additional information regarding the reasons the Company uses non-GAAP measures, a reconciliation of these measures to the most directly comparable GAAP measures, and other information relating to these measures are included below, following the GAAP financial information.

Forward-Looking Statements Notice:

The foregoing paragraphs contain 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. Such forward-looking statements include, but are not limited to, statements relating to: our belief that we will increase our cadence of new hardware products, solutions, and software stacks, including the launch of Nexus, our next-generation FPGA platform; our belief that we achieve our financial model targets; and the statements under the heading “Business Outlook - First Quarter of 2020.” 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 are inherently uncertain due to such factors such as global economic conditions which may affect customer demand, pricing pressures, competitive actions, and international trade disputes and sanctions. 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 results may differ materially from our expectations and are subject to risks and uncertainties that relate more broadly to our overall business, including those risks more fully described in Lattice’s filings with the SEC including its Annual Report on Form 10-K for the fiscal year ended December 29, 2018, and Lattice’s quarterly reports filed on Form 10-Q. Lattice believes these and other risks and uncertainties could cause actual results to differ materially from the forward-looking statements. You should not unduly 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 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. The non-GAAP measures presented exclude charges and adjustments primarily related to stock-based compensation, restructuring plans and related charges, acquisition-related charges, amortization and impairment of acquired intangible assets, inventory adjustments related to restructured operations, loss on refinancing of long-term debt, and the estimated tax effect of these items. 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.

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.
