Lattice’s low-power FPGA strategy as “companion chips” to major processors is driving higher attach rates in data center and physical AI use cases. Record design-win velocity, stronger security workloads, and a larger new-product mix set the stage for continued growth momentum into FY 2026.

• Lattice Semiconductor’s Q4 FY 2025 financial results
• Companion FPGA momentum in data centers
• Security attach and ASP mix expansion
• New product ramps and design wins
• Guidance and Final Thoughts

The News: Lattice Semiconductor (NASDAQ: LSCC) reported Q4 FY 2025 revenue of $145.8 million, up 24.2% year-on-year (YoY), versus Wall Street consensus of $143.1 million. Communications and Computing revenue was $92.6 million, while Industrial and Automotive revenue was $44.1 million. Non-GAAP gross margin was 69.4%, expanding from 62.1% in the prior year. Non-GAAP operating income was $44.8 million (Q4 FY 2024: 20.1 million), with a non-GAAP operating margin of 30.7% (Q4 FY 2024: 17.1%). Non-GAAP net income was $43.7 million (+116.7% YoY), and non-GAAP diluted EPS was $0.32, up from $0.15 in Q4 FY 2024.

“2025 was a pivotal year where we delivered on what we said we would do: stabilized revenue, normalized channel inventories, and drove exceptional data center growth, with server revenues up approximately 85% YoY,” said Ford Tamer, chief executive officer. “We finished the year with strong momentum led by accelerating growth in AI and datacenters, higher Lattice FPGA attach rates per system and increasing ASPs as diversified customers move to our newer product platforms and solutions. When taken together, we believe we are positioned for higher growth in 2026 and beyond.”

Lattice Semiconductor Q4 FY 2025: Record Comms & Compute, AI Servers +85%

Analyst Take: Lattice capped FY 2025 with strong Q4 execution and a mix shift aligned to AI infrastructure and “physical AI” edge systems. The company’s “companion chip” strategy—low-power FPGAs that manage boot, security, control, and I/O adjacent to CPUs/GPUs/accelerators—continues to expand attach rates with hyperscalers and OEMs. Segment performance skewed to Communications & Computing, with data center servers the fastest-growing vector and wired comms also contributing. New products (Nexus/Avant) are scaling, helping lift average selling prices (ASPs) as security and larger FPGA use cases ramp. With record design wins and improving channel alignment, Lattice enters FY 2026 with momentum tied to AI server builds and expanding near-sensor workloads.

Data Center Companion FPGA Momentum

Management emphasized servers as the top growth driver within Communications & Computing in FY 2025, with server revenue up approximately 85% YoY and AI servers the fastest-growing subsegment. Lattice cited design wins across all major GPU and AI accelerator platforms, with content and attach rates increasing each generation across NVIDIA and custom silicon at top cloud providers. The team highlighted a rapid upward revision in top-five hyperscaler capital expenditure outlooks over the past three months, reinforcing multi-quarter AI infrastructure visibility. As data center systems disaggregate into boards for compute, networking, security, power, and storage, Lattice FPGAs appear “everywhere,” supporting control and real-time coordination functions. This breadth supports diversified growth and strengthens the company’s position as a neutral enabler across vendor ecosystems (“Switzerland” positioning). Together, these dynamics indicate sustained data center momentum as AI deployments broaden and deepen.

Security Attach and ASP Mix Expansion

Through FY 2025, Lattice expanded into higher-value security use cases—attestation, post-quantum cryptography, and newly discovered “leakage detection” in AI infrastructure—where latency and deterministic response are critical. These workloads require larger devices and richer IP, driving higher ASPs and deeper system integration over time. Management noted that as newer generations of accelerators roll out, Lattice’s content per system increases, reinforcing the companion-chip model. Wired communications also outpaced wireless within comms, aligning with the networking and control needs of AI clusters. Traditional server activity also improved, broadening the base beyond AI-only builds. The cumulative effect is an improving mix as security and control attach rates expand across server and networking platforms.

New Products and Design-Win Trajectory

New product revenue grew approximately 70% in FY 2025, lifting the new product mix to the low-20% range of total revenue, with expectations for mid-to-high 20% in FY 2026 as Nexus and Avant adoption scales. The company reported record design-win performance every quarter in FY 2025, with lifetime value building and ramps anticipated through FY 2026–2027. Management framed this pipeline as supportive of at least a 25% multi-year growth trajectory, contingent on execution and supply. The product portfolio expanded by roughly 60% in FY 2025, and FY 2026 plans include further devices, enhanced Radiant tool support, IP, and enablement to extend leadership in small FPGAs and grow mid-range share. Lattice also completed four small IP/software tuck-ins to accelerate tools and solutions, with more in the pipeline; larger M&A remains a possibility but only under strict strategic and accretive criteria. This combination of product cadence, design-in velocity, and selective tuck-ins provides operating leverage into the ramp.

Guidance and Final Thoughts

For Q1 FY 2026, Lattice guided revenue to $158 million–$172 million (consensus estimate $148.1 million), non-GAAP gross margin of 69.5% ± 1% (consensus estimate 69.7%), non-GAAP operating expenses of $59 million–$61 million, non-GAAP tax rate of 4%–6%, and non-GAAP EPS of $0.34–$0.38; the revenue midpoint implies growth above last year’s level and outpaces consensus entering the print. Management underscored tightness in substrates and assembly and is coordinating allocations across customers and partners, while customers indicate memory supply is covered by existing agreements. Capital return continues with a new $250 million repurchase authorization following $100 million in buybacks during FY 2025, reflecting balance sheet flexibility. Strategic priorities emphasize scaling software, IP, and enablement to support growing attach rates in data center and physical AI while preserving margin discipline. Execution on supply and ramp timing remains a key watch item into FY 2026.
