Lattice Semiconductor Soars on Growth, Margins and AMI Deal

Lattice Semiconductor Corporation ((LSCC)) has held its Q1 earnings call. Read on for the main highlights of the call.

Lattice Semiconductor’s latest earnings call struck an upbeat tone, as management highlighted powerful revenue growth, expanding margins, and a transformative acquisition that could push the business beyond a $1 billion run rate. While they acknowledged cost inflation, supply-chain tension, and higher spending, the overall message was one of accelerating momentum and confidence in long-term demand.

Strong Top-Line Acceleration

Lattice reported Q1 revenue of $170.9 million, up 42% year-over-year and 17% sequentially, reflecting broad-based strength across its portfolio. Management emphasized that demand was solid across end markets, underscoring how its low-power FPGA offerings are gaining traction with a growing set of customers.

Compute and Communications Lead the Charge

Compute and communications posted record revenue, jumping 86% year-over-year and 15% sequentially, and accounted for 62% of total Q1 sales. Leadership underscored robust server and networking demand, highlighting Lattice’s rising exposure to data center and AI use cases as a key structural growth driver.

EPS and Margin Expansion Impress

Non-GAAP EPS surged roughly 86% compared with last year to $0.41, a 30% sequential increase, as operating leverage kicked in. Non-GAAP gross margin reached about 70%, up 100 basis points year-over-year, while operating margin climbed to 34.4% and EBITDA margin to 39.6%, signaling strong profitability.

Q2 Outlook Points to Continued Momentum

For the second quarter, Lattice guided revenue to a range of $175 million to $195 million, with the midpoint implying nearly 50% year-over-year growth. The company also projected non-GAAP EPS of $0.42 to $0.46 and gross margin around 70%, reinforcing the view that its growth and margin story still has room to run.

Healthier Channels and Deep Backlog

Management noted channel inventory fell from roughly three months to around two months and is expected to dip below that in Q2, reducing overhang risk. At the same time, bookings are accelerating and the company now carries a backlog that stretches into 2027, providing strong visibility into future revenue.

Transformational AMI Acquisition

Lattice announced a definitive agreement to acquire AMI for about $1.65 billion, split between cash and equity, in what management framed as a transformative deal. They expect the transaction to be immediately accretive to gross margin, free cash flow, and EPS, and to roughly double the combined addressable market to about $12 billion over the next few years.

Path to a $1 Billion Run Rate

With AMI included, Lattice expects to exceed a $1 billion annual revenue run rate by year-end, pointing to significant scale benefits. The company also highlighted a strong cash generation profile, with roughly 40% free cash flow conversion on that run rate, $15 million of stock buybacks in Q1, and no debt on the balance sheet.

Industrial and Embedded Demand Rebounds

Industrial and embedded revenue grew more than 20% sequentially, helped by rising orders in factory automation, robotics, and medical applications. Management framed this as an early-stage recovery in a key segment, suggesting additional upside as industrial customers continue to digitize and automate.

Supply-Chain and Cost Pressures

While legacy-node wafer supply has improved, Lattice is experiencing pressure in backend assembly and testing, which could weigh on costs later in the year. The company is broadening its supplier base to relieve capacity constraints, but warned investors that cost inflation will likely be more visible in the second half.

Near-Term Cash Flow Compression

Operating cash flow in Q1 was $50.3 million and free cash flow was $39.7 million, both down sequentially due to annual bonuses and revenue linearity. Management characterized this as timing-related rather than structural, pointing to continued strong profitability and cash generation potential as growth persists.

Higher Operating Expenses to Fund Growth

Non-GAAP operating expenses rose about 8% sequentially and 18% year-over-year to $60.8 million, driven largely by performance-based compensation and growth investments. Executives argued that these expenses are necessary to support an expanding product road map and sales footprint, even as margins remain robust.

Funding the AMI Deal and Integration Risks

The AMI deal requires roughly $1 billion of cash at closing, which will significantly draw upon Lattice’s resources beyond the $140 million cash balance reported in Q1. Management acknowledged typical integration and execution risks around such a large transaction, with the closing targeted for early Q3, but reiterated confidence in the strategic fit.

Margin Outlook Faces H2 Uncertainty

Lattice reiterated a working non-GAAP gross margin range of about 69.5% plus or minus 1%, even as it flagged higher costs in the back half of the year. Investors should expect some margin volatility as supply-chain costs move higher, though management believes it can largely defend its strong profitability profile.

Rising Exposure to Servers and AI

The company noted that server-related revenue now represents roughly 38% of sales, with AI-related business expected to contribute about 25% of revenue in 2026. While this concentration offers powerful growth tailwinds, it also increases sensitivity to data center and AI spending cycles, a risk management says it is monitoring.

Guidance Underscores Confidence in Growth Trajectory

Lattice’s Q2 guidance calls for continued strong revenue expansion, high-70s EPS growth, and gross margins around 70%, all on a standalone basis before AMI closes. Management reiterated that the AMI acquisition should be immediately accretive and help drive the combined company past a $1 billion revenue run rate by year-end, signaling confidence in both demand and execution.

Lattice Semiconductor’s earnings call painted the picture of a company firing on multiple cylinders, with rapid growth, expanding margins, and a bold strategic acquisition setting the stage for its next phase. While investors must weigh supply-chain costs, higher spending, and increased exposure to server and AI cycles, the overall narrative remains one of strong momentum and rising scale.
