Lattice Semiconductor Corporation reported fiscal fourth‑quarter 2025 results that surpassed revenue expectations while meeting earnings estimates. Total revenue rose 24.2% year‑over‑year to $145.8 million, driven by a 60% increase in Communications & Computing revenue to $92.6 million and an 85% jump in server revenue. GAAP net income was a loss of $7.6 million, translating to a diluted loss per share of $(0.06), but non‑GAAP diluted earnings per share matched the consensus estimate of $0.32, a beat of $0.00 in absolute terms but a 0% beat in percentage terms. The company’s GAAP gross margin for the quarter was 68.5%, up from 66.8% in Q4 2024, while non‑GAAP gross margin expanded to 69.3%, reflecting a favorable mix shift toward higher‑margin data‑center products and effective cost control.
The Communications & Computing segment, the company’s core growth engine, generated $92.6 million in revenue, up 60% year‑over‑year and 25% sequentially, as demand for low‑power FPGA companion chips in AI data‑center platforms accelerated. Server revenue, a key driver of margin expansion, grew 85% year‑over‑year to $45.2 million, supported by higher attach rates and pricing power in the AI market. In contrast, the Industrial & Automotive segment declined 18% year‑over‑year to $12.4 million, a result of planned channel inventory normalization that reduced sales in legacy product lines.
Margin performance reflected the company’s pricing strength and efficient cost structure. GAAP gross margin improved to 68.5% from 66.8% in the prior year, while non‑GAAP gross margin rose to 69.3% from 68.2%, driven by a higher mix of high‑margin data‑center and server revenue and disciplined cost management. Operating income increased to $12.4 million, up from $9.8 million in Q4 2024, as the company leveraged scale and maintained pricing power despite modest increases in raw material costs.
Lattice raised its first‑quarter 2026 revenue guidance to a midpoint of $165 million, within a range of $158–$172 million, and lifted its diluted EPS guidance to $0.34–$0.38, up from the previous $0.32–$0.36 range. The guidance reflects management’s confidence in continued AI and data‑center demand, as well as the expected acceleration of low‑power FPGA adoption in new server platforms. The company also reiterated its commitment to maintaining non‑GAAP gross margins above 69% for the year, signaling sustained pricing power.
CEO Ford Tamer emphasized that 2025 was a pivotal year, noting that “we delivered on our strategic priorities, stabilized revenue, normalized channel inventories, and drove exceptional data‑center growth, with server revenues up approximately 85% year over year.” He added that the company is positioned for higher growth in 2026 and beyond, underscoring the importance of the AI market and the company’s low‑power FPGA portfolio. Market analysts highlighted the strong revenue beat and the raised guidance as key drivers of investor optimism, citing the company’s ability to capture growing AI workloads and its disciplined cost management.
The results underscore both tailwinds and headwinds. The surge in data‑center demand and AI adoption provides a robust tailwind, while the planned inventory normalization in the Industrial & Automotive segment and ongoing supply‑chain constraints in substrates and assembly present headwinds. Nevertheless, the company’s focus on high‑margin data‑center products, disciplined cost control, and strategic investments in low‑power FPGA technology position it well for sustained growth in the coming years.
