Gross margin improved to 69.3% (non-GAAP), reflecting a favorable mix shift toward higher-value new products and disciplined pricing. Operating leverage was evident, as EBITDA margin expanded to 34.1%, and free cash flow margin climbed to 25.2%, up sharply from Q1. Industrial and automotive revenues declined as Lattice continued to undership true demand to normalize channel inventory, but management reaffirmed that these channels are on track for normalization by year-end, setting the stage for renewed segment growth in 2026.
- Server Attach Rate Surge: Lattice’s attach rates in AI and traditional servers rose rapidly, driving outsized revenue growth in compute.
- Channel Inventory Burn: Sell-through remained above sell-in in industrial and auto, supporting management’s claims of inventory normalization by year-end.
- New Product Momentum: New products are pacing to exceed 2025 targets, with management forecasting 70% YoY growth in this category.
Capital allocation remained shareholder friendly, with buybacks matching operating cash flow for the first half of the year. The company’s debt-free balance sheet and strong cash generation provide ample flexibility for both investment and capital returns.
Executive Commentary
"Communications and compute demand remains strong with normalized inventory and continued growth expected through the second half and beyond. We believe we've passed the bottom with channel inventory levels decreasing as we continue to recognize revenue under channel point of sales outflows."
Ford Tamer, Chief Executive Officer
"Our gross margin expanded by 30 basis points quarter-and-quarter and year-on-year to 69.3% on a non-GAAP basis. This performance continues to reflect the durability of our business model with continued growth in higher-margin new products and markets and anticipated share gain as strategic customers."

Strategic Positioning
1. AI Infrastructure Companionship as Growth Engine
Lattice’s focus on “companionship” FPGAs, which support AI accelerators and networking chips in data centers and edge applications, is proving to be a defining advantage. Management highlighted a surge in attach rates, with FPGAs per rack ranging from 70 to 130 units, and emphasized their “processor-agnostic” positioning, enabling wins across XPU, GPU, and AI-specific architectures. This role as a low-power, small-footprint enabler is increasingly critical as hyperscale CapEx accelerates, with Lattice’s solutions complementing, not competing with, ASICs and MCUs.
2. Channel Inventory Discipline Unlocking 2026 Growth
Management’s strategy of undershipping true demand in industrial and automotive is on track to restore channel inventory to normal levels by year-end. This deliberate approach has temporarily suppressed segment revenue but is expected to enable significant rebound in 2026, supported by record design wins in industrial automation, robotics, and emerging “humanoid” applications. Automotive remains a small but stabilizing contributor, with China and Europe showing relative strength.
3. Mix Shift Toward High-Value New Products
New product revenue is pacing to grow 70% YoY, with management targeting mid-20s percent of total revenue from new products by 2026. The current revenue mix is dominated by the Nexus family, with Avant’s contribution expected to scale meaningfully in late 2026 and beyond. This mix shift is supporting gross margin durability and aligning Lattice with secular trends in security, post-quantum cryptography, and sensor fusion for far-edge AI.
4. Operational Leverage and Cost Discipline
Operating expenses remain tightly controlled, with OpEx down YoY despite flat revenue, reflecting ongoing restructuring and prioritization of R&D. Management reiterated a long-term target of 30% OpEx as a percent of revenue, but is prioritizing growth investments as the top line recovers. Free cash flow growth is a focus, with CapEx targeted at R&D and operational improvements rather than capacity expansion.
5. Resilient Supply Chain and Tariff Mitigation
Lattice’s diversified supply chain, with sourcing from Japan, South Korea, and Malaysia, and use of free trade zones, insulates the company from direct tariff shocks such as Section 232. Management has seen no material impact from recent geopolitical volatility, and continues to work with customers to optimize supply chains as needed.
Key Considerations
This quarter marks a pivotal moment for Lattice’s positioning as a critical enabler in the AI infrastructure stack, with strong design win momentum, disciplined inventory management, and a durable margin profile. Investors should weigh the following:
Key Considerations:
- AI Server Proliferation: Record attach rates and content per rack signal Lattice’s deepening role in hyperscale deployments.
- Inventory Normalization Catalyst: Deliberate undershipping in industrial and auto sets up for a volume and margin tailwind in 2026.
- Margin Upside from Product Mix: New product growth and higher ASPs are structurally supporting gross margin expansion.
- Capital Return Philosophy: 100% of operating cash flow returned via buybacks in H1 reflects shareholder alignment.
- Emerging End Markets: Robotics, vision systems, and far-edge AI represent incremental TAM expansion for 2026 and beyond.
Risks
Inventory normalization in industrial and auto is not yet complete, and any demand softening or macro disruption could delay the expected rebound. AI infrastructure spending, while robust, is exposed to hyperscale CapEx cycles and potential competitive encroachment from larger FPGA peers. Tariff and geopolitical risks remain, though management has mitigated direct exposure. Investors should monitor for execution risk as Avant ramps and as channel sell-through is tested in a normalizing demand environment.
Forward Outlook
For Q3 2025, Lattice guided to:
- Revenue of $128 million to $138 million (midpoint $133 million, +7.2% QoQ)
- Non-GAAP gross margin of 69.5% (+/- 1%)
- Non-GAAP operating expenses of $52 million to $54 million
- Non-GAAP EPS of $0.26 to $0.30
For full-year 2025, management reaffirmed:
- Channel inventory normalization by year-end
- Strong growth in comms and compute, with industrial and auto set to rebound in 2026
Management highlighted several factors that support the outlook:
- Record backlog and bookings visibility into Q4 and early 2026
- Continued strength in server attach rates and new product pipeline
