Lattice Semiconductor Corporation (LSCC) Earnings: Q3 Fiscal 2026 Results

The quarter ended October 3, 2026 and Lattice Semiconductor published the results on November 2, 2026. Revenue and diluted EPS are shown against Q3 fiscal 2025, the same quarter a year earlier, which takes seasonal swings out of the comparison. Lattice Semiconductor reports EPS two ways: GAAP, under the accounting rules every US filer follows, and non-GAAP net income per diluted share, which leaves out items the company considers outside its operating results. The release reconciles the two, and when they diverge, the reconciliation says why.

• Lattice completed its acquisition of AMI on July 27, 2026. Q3 fiscal 2026 includes AMI from that date and the year-ago quarter does not. From Q3 Lattice reports two segments: FPGA and AMI.
• Since Q1 2026 Lattice reports end markets as Compute and Communications and Industrial and Embedded (which combines the former Industrial and Automotive and Consumer markets), with prior periods recast.
• Lattice uses a 52 or 53-week fiscal year ending on the Saturday closest to December 31. Q3 fiscal 2026 ended October 3, 2026 and Q3 fiscal 2025 ended September 27, 2025.

How Lattice Semiconductor splits revenue in its own release, under its own labels, for Q3 fiscal 2026 against Q3 fiscal 2025. Indented lines are parts of the line above them.

• Lattice Semiconductor's Compute and Communications revenue was $172 million in Q3 fiscal 2026, up 132% from $74.0 million in Q3 fiscal 2025, 59% of total revenue.
• Lattice Semiconductor's Industrial and Embedded revenue was $80.1 million in Q3 fiscal 2026, up 35% from $59.3 million in Q3 fiscal 2025, 28% of total revenue.
• Lattice Semiconductor's AMI revenue was $39.1 million in Q3 fiscal 2026, 13% of total revenue.

Segment lines are the figures writers cite most often, because they show where the growth in a quarter came from. Companies redraw their segments from time to time and restate the prior year to match, so a year-ago figure here can differ from the one printed a year ago. When that has happened, the note above says so.

From the earnings release

In its Q3 fiscal 2026 release, Lattice Semiconductor said:

“Lattice revenue for the fourth quarter of 2026 is expected to be between $325 million and $345 million.”

“Lattice gross margin for the fourth quarter of 2026 is expected to be 72.0% plus or minus 1% on a non-GAAP basis.”

“Total operating expenses for the fourth quarter of 2026 are expected to be between $95 million and $101 million on a non-GAAP basis.”

“Net income for the fourth quarter of 2026 is expected to be between $0.82 and $0.86 per share on a non-GAAP basis.”

• Q3 fiscal 2026 (this page), reported Nov 2, 2026

Lattice Semiconductor's Q3 fiscal 2026 revenue of $291.0 million was up 118.3% from $133.3 million, and it is the first quarter to include AMI, the platform firmware and infrastructure manageability company Lattice bought on July 27, 2026. AMI contributed $39.1 million. The FPGA business supplied the rest: Compute and Communications $171.9 million and Industrial and Embedded $80.1 million. (Lattice Semiconductor Q3 2026 release, Nov 2, 2026; Lattice Semiconductor Form 10-Q, Q3 fiscal 2026, Nov 3, 2026)

Compute and Communications revenue rose 132%, which Lattice attributed mainly to data center demand, including general-purpose and AI-specific servers, and to wireline networking components. Industrial and Embedded rose 35% on recovering demand, particularly from industrial and aerospace customers. Lattice said revenue from new products grew more than 70% and is tracking toward 25% of FPGA revenue in 2026. (Lattice Semiconductor Form 10-Q, Q3 fiscal 2026, Nov 3, 2026; Lattice Semiconductor Q3 2026 release, Nov 2, 2026)

Lattice paid about $1.6 billion for AMI: total purchase consideration of $1,589.7 million, combining cash, about 5.2 million Lattice shares and restricted stock units, and $272.2 million to retire AMI's credit agreement. AMI sells mainly through direct customer relationships, and its revenue is driven by the buildout of general purpose and AI server infrastructure in data centers. (Lattice Semiconductor Form 10-Q, Q3 fiscal 2026, Nov 3, 2026)

The FPGA business sells mostly through distributors. Distribution was 81% of Q3 fiscal 2026 revenue, against 83% a year earlier, and in fiscal 2025 two distributors accounted for about 69% of total revenue. By geography, 76% of Q3 revenue came from Asia, 16% from the Americas and 8% from Europe. (Lattice Semiconductor Q3 2026 release, Nov 2, 2026; Lattice Semiconductor Form 10-Q, Q3 fiscal 2026, Nov 3, 2026)

Lattice Semiconductor's GAAP diluted EPS was $0.08 in Q3 fiscal 2026 and its non-GAAP diluted EPS $0.72, against $0.02 and $0.28 a year earlier. The gap is wide because GAAP results carry $50.7 million of stock-based compensation, $25.9 million of acquisition-related costs and $12.9 million of amortization of intangibles acquired with AMI, all of which Lattice excludes from non-GAAP figures. (Lattice Semiconductor Q3 2026 release, Nov 2, 2026)

Financing the deal changed the bottom of the income statement. Net interest expense was $9.6 million, against net interest income of $0.6 million a year earlier. GAAP net income was $11.2 million, against $2.8 million, while non-GAAP net income was $103.7 million. (Lattice Semiconductor Q3 2026 release, Nov 2, 2026)

Shares issued for AMI raised the share count. Diluted shares were 143,772 thousand in the quarter, against 138,103 thousand a year earlier. (Lattice Semiconductor Q3 2026 release, Nov 2, 2026)

Diluted EPS divides net income by the weighted average number of shares outstanding in the quarter, plus the shares that options and other equity awards could add. Buybacks shrink that count and lift EPS for the same profit; share issuance and stock awards enlarge it.

Lattice Semiconductor gives next-quarter guidance in its release, mostly on a non-GAAP basis. For Q4 fiscal 2026 it expects revenue of $325 million to $345 million, non-GAAP gross margin of 72.0% plus or minus 1%, non-GAAP operating expenses of $95 million to $101 million and non-GAAP EPS of $0.82 to $0.86. The release headline puts expected Q4 revenue growth at about 130% year over year, with Industrial and Embedded growth accelerating to 70%. (Lattice Semiconductor Q3 2026 release, Nov 2, 2026)

Lattice says it does not reconcile this outlook to GAAP because items such as stock-based compensation, amortization of acquired intangibles and acquisition charges cannot be reasonably calculated in advance. (Lattice Semiconductor Q3 2026 release, Nov 2, 2026)

A consensus figure is the average of the models published by the analysts who cover Lattice Semiconductor, collected by a data provider and revised up to the day of the report. A quarter that lands above it says how expectations were set as much as how the business did, and the share price on the day also reflects the guidance and the lines no consensus covers.

The consensus figures on this page are Yahoo Finance's, as pulled on the date shown. Each comes with the number of analysts behind it; the smaller that number, the more one revised estimate can move the average.

The figures below are the ones Lattice Semiconductor's own release and filings put weight on for Q3 fiscal 2026, with the latest reported value for each.

What the quarter means for a holding is a separate question from what it reported. The case for and against owning LSCC is on is LSCC a buy or a sell?, what analysts expect next is on the LSCC forecast, and what the company does is on the Lattice Semiconductor Corporation (LSCC) stock page.

Every number on this page can be traced to a document Lattice Semiconductor published. Checking one takes a couple of minutes, and it is worth doing before you quote a figure anywhere.

• The results release is the document linked in the source line above. Companies publish it on their investor relations site at the moment results go out, and it carries the headline tables: revenue, operating income, net income and EPS for the quarter and the year-ago quarter.
• The same release is filed with the SEC as Exhibit 99.1 to a Form 8-K under Item 2.02, usually on the day of the report. The SEC copy does not change after the fact, which makes it the safer thing to link when you cite a number.
• The quarterly report (Form 10-Q) follows within a few weeks and carries the full financial statements, the segment note and management's discussion of what changed. The fourth quarter is covered by the annual report (Form 10-K) instead.
• Restated comparisons are flagged in the notes on this page. When a company redraws its segments or changes how it adjusts EPS, it restates the year-ago column, so the year-ago figure in a new release can differ from the one printed a year ago. This page always uses the comparison in the newer release, because that is the like-for-like one.
