Lattice Semiconductor shares jumped 5.8% on Monday to close at $128.50, touching a fresh 52-week high near $151 intraday, even as the broader chip sector sits more than 20% below its summer peak.
The PHLX Semiconductor Index has shed roughly $1 trillion in combined market value since late July on fears that AI infrastructure spending can't keep paying for itself. Lattice just kept climbing anyway. The small FPGA maker out of Hillsboro, Oregon is up roughly 92% year to date - a run that has quietly outpaced both Nvidia and AMD. Its chart looks nothing like the rest of its industry right now.
The trigger was Lattice's first-quarter 2026 results. Revenue hit $170.9 million, up 42% year over year, and non-GAAP earnings came in at $0.41 a share, beating Wall Street's $0.37 estimate, according to a transcript of the earnings call published by Investing.com. The growth wasn't spread evenly across the business: it was concentrated in one place. The Compute & Communications segment, which sells FPGAs into AI servers and data-center networking gear, surged 86%.
That's the story in a sentence. AI data centers need more than GPUs. They need the smaller chips that manage power sequencing, security and traffic around them, and Lattice makes those chips.
Wall Street was already ahead of this #
Wall Street had already started rerating this stock before Monday's move, and the numbers tell it. Deutsche Bank raised its target from $150 to $175 back in May. TD Cowen lifted its from $145 to $165 in July. Stifel and RBC, earlier in the year, set theirs at $145 and $140 respectively. Even after Monday's 5.8% pop, Lattice is still trading below several of those targets. That's rare. It's already roughly tripled off its 52-week low of $46.43.
Then there's the AMI deal. Lattice closed its $1.65 billion acquisition of AMI on July 27 - a cash-and-stock purchase, about $1 billion in cash and $650 million in shares, that bolts AMI's platform firmware and server-management software onto Lattice's low-power FPGA business. Lattice has said the deal should be accretive to gross margin and free cash flow - non-GAAP earnings too - and that it supports the company's goal of a $1 billion annual revenue run rate by the end of 2026. For a company that just did $170.9 million in a single quarter, that's an aggressive target. It depends almost entirely on AI infrastructure spending not slowing down.
A sector that has stopped believing itself #
Here's the divergence that makes this worth watching. Intel, Nvidia, SK Hynix and Samsung have all taken hits over the past two weeks as investors question whether the roughly $740 billion that Microsoft, Amazon, Alphabet, Meta and Oracle plan to spend on AI infrastructure this year will generate enough return to justify it. Bloomberg has described the selloff as a "loss of confidence" rather than a demand problem. Lattice hasn't been swept up in that anxiety, at least not yet, because its numbers are showing the demand instead of just promising it.
Frankly, that's the risk too. A company growing 42% on the back of one customer category can shrink just as fast if that category cools. Lattice doesn't break out customer concentration in detail, and right now the entire investment case rests on AI data-center spending holding its current pace through the back half of 2026. Analysts at Stifel, Deutsche Bank, RBC and TD Cowen are betting it will. The market that wiped $1 trillion off chip stocks in a month is betting it might not.
Lattice's own guidance suggests it isn't worried yet. The company guided second-quarter revenue to a range of $175 million to $195 million, above what Wall Street had penciled in. If that holds, Lattice will have grown revenue for two straight quarters while the index it trades alongside was falling apart around it.
