Lattice Faces Its First AMI Quarter As Stock Slumps Despite A Billion-Dollar Run Rate

Lattice Semiconductor heads into its third-quarter report with an unusual disconnect. Three months ago management delivered record revenue, expanding margins, a closed acquisition and an outlook that pulled its $1 billion annualized revenue target forward by a full quarter. Since then the stock has fallen 27.3%, trailing the S&P 500 by about 25 percentage points. The November 2 report, due after the close, is the first real chance to show whether that selloff reflects doubts about execution or simply a market that stopped paying for the story.

The Street is looking for non-GAAP earnings of $0.55 per share on revenue of $255.1 million, which would be growth of roughly 91% from the year-ago quarter. Much of that leap comes from AMI, the deal that closed on July 27 and contributes about two months to the quarter. Management's published range of $210 million to $230 million appears to frame the base business, while the combined outlook including AMI centered near $255 million, so consensus sits right on the midpoint rather than leaning on optimism. On earnings, the $0.55 estimate falls in the lower half of the $0.54 to $0.58 guidance range. The whisper number of $0.58 sits at the top of that range, signaling that the more engaged crowd expects Lattice to keep its habit of landing at or above the high end, though the gap is a few cents, not a chasm.

The operational test is twofold. First, the core FPGA business needs to show that the second-quarter surge was not a one-off. Revenue climbed 18% sequentially to a record $201 million on data-center AI strength in compute and communications, with server attach rates above three FPGAs per server and average selling prices over $4. Industrial and embedded also rebounded. Management went further by describing 2027 as essentially booked, an unusually long line of sight for a programmable logic supplier. Evidence that backlog is converting smoothly would validate that confidence; any hint of order pushouts or a stall in industrial recovery, including the China softness flagged last quarter, would undercut it. Second, AMI needs to look like the asset Lattice paid for: more than $200 million in run-rate revenue, 75%-plus gross margins and growth near 25%, with accretion promised starting in the fourth quarter.

Margins are where the noise lives. Combined gross margin was guided to 69.5%, plus or minus a point, down from 71.7%, because AMI carries a low-margin hardware pass-through being exited by the end of 2026. A figure inside that band would be in line with the plan. A reading near the bottom would raise questions about whether rising supply-chain costs and expedite fees are biting harder than expected. Management targeted supply and demand balance by September, so commentary on back-end assembly capacity matters: if constraints persist, they cap upside in a quarter where demand is not supposed to be the problem. The $925 million term loan and the goal of leverage below 2 times EBITDA by end-2027 make free cash flow, which jumped to $81.3 million last quarter, more than a footnote.

Sentiment has cooled noticeably, slipping from mildly bullish before the last report to slightly bearish now, and the shares at $96.19 sit well below the 200-day moving average of $115.19 and just above the post-earnings low of $94.31. That positioning lowers the bar for a relief rally, but it also shows how little benefit of the doubt remains.

The central question is whether Lattice can confirm the $1 billion run rate with clean AMI integration, gross margin inside the guided band and an outlook pointing toward its stated $1.2 billion exit rate for 2026. Deliver that, and the selloff looks like a sentiment problem. Stumble on supply or margins, and the market's skepticism gains a factual foundation.
