Silicom Secures Design Win for Custom High-Speed Server Adapter

– Total annual revenue from the customer is expected to scale from  ~$3 million in 2026 to ~$10 million in 2027 – KFAR SAVA, Israel – July 16, 2026 – Silicom Ltd. (NASDAQ: SILC), a leading provider of networking and data infrastructure solutions, today announced that an existing blue-chip customer has awarded it a new Design Win for a custom high speed server adapter engineered to the customer's exact specifications.

This new Design Win addresses a distinct functionality and use case within the customer's infrastructure, separate from everything else the customer currently purchases from Silicom. Revenue from this Design Win will commence in 2026 and is projected to ramp to more than $5 million in 2027. Consequently, the customer anticipates its total business with Silicom will expand from approximately $3 million in 2026 to nearly $10 million in 2027.

“This latest Design Win powerfully validates the trust this customer places in our technical capabilities and delivery execution,” commented Liron Eizenman, Silicom's CEO. “Over the past year, this customer successfully integrated one of our off-the-shelf server adapters as well as an FPGA Smart NIC. Returning to us for a fully custom server adapter engineered to its precise specifications is a clear indicator: when industry leaders require mission-critical, differentiated performance, they turn to Silicom.”

Mr. Eizenman continued, “This win perfectly illustrates how our product lines are mutually reinforcing, with each successful deployment opening the door to the next. It further underscores the compounding value of our long-term, trusted-supplier relationships we have cultivated over decades of operation. This solid, predictable platform of recurring revenues drives the inflection point of our core business, supporting our goal of strong, continuous growth in the years ahead.”
