Insights

Equity research analyst – technology hardware

Silicom is returning to revenue growth while still operating at a loss, with guidance pointing to faster expansion in 2026.

Silicom delivered Q4 2025 revenue of $16.9 million, up 17% year over year, and full-year 2025 revenue of $61.9 million, up 7%. Losses narrowed, with GAAP net loss improving to $2.5 million in Q4 and $11.5 million for the year.

Non-GAAP net loss also improved to $1.9 million for Q4 and $8.1 million for 2025 as operating expenses grew more slowly than sales. Management highlights design win momentum and demand across Edge systems, Smart NICs and FPGA-based adapters as key drivers.

Guidance for Q1 2026 revenue of $16.5–$17.5 million implies about 18% year-over-year growth at the midpoint and underpins expectations for double-digit growth in 2026. Future filings and updates on design wins and uptake in AI inference, Post-Quantum Cryptography and white-label switching markets may clarify how quickly losses can narrow further.

FOR IMMEDIATE RELEASE

EARNINGS RELEASE

Silicom Reports Q4 and Full Year 2025 Results

Ahead-of-plan performance of core business -
- Pursuing venture-scale upside from exploding AI Interference, Post-Quantum Cryptography

and White-Label Switching markets -

KFAR SAVA, Israel, January 29, 2026 - Silicom Ltd. (NASDAQ: SILC), a leading provider of high-performance networking and data infrastructure solutions, today reported its financial results for the fourth quarter and full year ended December 31, 2025.

Financial Results

Fourth quarter: Silicom’s revenues for the fourth quarter of 2025 totalled $16.9 million, a 17% increase compared with $14.5 million for the fourth quarter of 2024.

On a GAAP basis, the company’s net loss for the quarter was $2.5 million, or $0.44 per ordinary share (basic and diluted), compared with $6.1 million, or $1.05 per ordinary share (basic and diluted), for the fourth quarter of 2024.

On a non-GAAP basis (as described and reconciled below), net loss for the quarter totalled $1.9 million, or $0.34 per ordinary share (basic and diluted), compared with $5.1 million, or $0.87 per ordinary share (basic and diluted) for the fourth quarter of 2024.

Full year 2025: Silicom’s revenues for 2025 were $61.9 million, an increase of 7% compared with $58.1 million for 2024.

On a GAAP basis, net loss for the year totalled $11.5 million, or $2.01 per ordinary share (basic and diluted), compared with $13.7 million, or $2.28 per ordinary share (basic and diluted), for 2024.

On a non-GAAP basis (as described and reconciled below), net loss for the year totalled $8.1 million, or $1.41 per ordinary share (basic and diluted), compared with $10.0 million, or $1.66 per ordinary share (basic and diluted), for 2024.

Guidance

Management projects that revenues for the first quarter of 2026 will range from $16.5 million to $17.5 million, representing 18% growth year-over-year in the mid-range of the guidance. This affirms the Company’s expectation of generating double digit annual growth in 2026. 

Comments of Management  

Liron Eizenman, Silicom’s President and CEO, commented, “We are pleased to report better-than-projected growth for 2025 as a whole, with on-track Design Win momentum and 17% year-over-year growth for the fourth quarter. We achieved 8 new Design Wins during the year while continuing to expand the pipeline for our core solutions: Edge systems, Smart NICs and FPGA-based adapters. Many of our global customers continued to bring us new opportunities: for example, a global security-as-a-service giant recently doubled its business with us after just one year of cooperation, becoming an $8-10 million-per-year customer. In the year ahead, we expect to achieve 7-9 new Design Wins along with double-digit growth.”  

Mr. Eizenman continued, “In parallel, we are extremely excited about three tectonic shifts currently underway in the technology infrastructure market that leverage our core expertise, capabilities, IP and customer base, offering us venture upside potential.

• AI Inference: AI investments are currently shifting from training to inference, creating a total addressable market for hardware-based AI inference solutions that will top $80+ billion by 2030. This explosive market’s need for our bottleneck-busting networking solutions is a massive incremental opportunity for Silicom, and we are already moving strongly to address it. One of our customers is conducting a PoC utilizing our Inference-Optimized FPGA-based solution for a hyperscaler end-user, and we are developing a dedicated AI-NIC for another AI Inference leader. We have first orders in hand, follow-on PoCs in progress, and we are in advanced discussions with additional AI inference chip vendors.

• Post-Quantum Cryptography (PQC): Although quantum computers will not be widely deployed for several years, suppliers must plan now to defend against ‘harvest now, decrypt later’ attack strategies. Driven by security risk and regulatory pressure, the PQC market is expected to grow to $3+ billion by 2030, and Silicom is one of the only existing providers of mature, production-ready, end-to-end hardware-based PQC accelerator solutions. As such, we are positioned to become a strong player in this market - and the fact that two leading customers have already selected us validates our technology and timing.

• White-Label Switching: as a leading supplier of white-label Edge, SD-WAN, and SASE platforms with proprietary IP building blocks and know-how, we are positioned to introduce white-label switching solutions, thereby disrupting a $6+ billion incumbent market. We have already designed and shipped samples of three switching platforms to a leading cyber security customer, and are in active discussions with additional customers regarding follow-on opportunities.”

Mr. Eizenman concluded, “In summary, our core business is growing faster than projected, and any one of these three upside opportunities could become a massive growth engine. All of this is a natural outgrowth of the unique platform we’ve built over the past 20 years: our thriving core business, our technological expertise, our proven ability to execute and our Tier-1 customer base. All of this is backed by a rock-solid balance sheet, which enables us to invest in venture-scale growth while maintaining our conservative financial profile.

“As a result, Silicom represents a unique convergence: a company with a stable growing core business that also offers realistic, immediate exposure to $100+ billion in new opportunities in some of IT’s hottest markets. We have the technology, the ‘fortress’ balance sheet and the customer trust to execute, and look forward to further scaling our core business as we work to capture venture-style upside.”
