– Initial commitment of ~$1M already in place;

discussions underway for next-generation platform and full system solution -

KFAR SAVA, Israel, April 15, 2026 /PRNewswire/ -- Silicom Ltd. (NASDAQ: SILC), a leading provider of networking and data infrastructure solutions, today announced that it has secured a Design Win with a European provider of advanced encryption and secure communication solutions for organizations requiring the highest level of protection for sensitive information. The customer selected a Silicom FPGA SmartNIC following a successful evaluation of one of Silicom's off-the-shelf products, which demonstrated the performance and reliability required for its advanced encryption solutions including Post Quantum Cryptography. During the coming months Silicom will customize the card to meet the customer's exact specifications, and expects to deliver the products per the customer's initial $1 million commitment during the second half of 2026, as it scales toward an anticipated annual deployment of approximately $3 million.

As a first step, the customer has already placed commitments totalling approximately $1 million, reflecting the depth of its confidence in Silicom as a technology and product partner. Looking ahead, Silicom and the customer are already engaged in discussions about a next-generation, higher-speed FPGA Smart NIC that the customer plans to launch in 2028, as well as a potential full system solution that combines a server with an FPGA Smart NIC. These are opportunities that could further expand the partnership and add meaningfully to Silicom's annual revenues from this customer.

"This encryption leader's selection of Silicom reflects the excellent performance of our off-the-shelf products, which it tested thoroughly, and its appreciation for our exceptional rapid customization capabilities," commented Liron Eizenman, Silicom's CEO. "It confirms our reputation as a leading player in FPGA SmartNIC Technology and a provider of unique encryption hardware acceleration solutions with backward compatibility and easy migration to PQC support."

Mr. Eizenman continued, "We are gratified that this prestigious technology leader has come to us in its quest for its next generation FPGA SmartNIC, and encouraged by ongoing discussions about additional offerings. This is a concrete demonstration of the trust with which this customer regards our company, confirming that our FPGA leadership continues to open doors with the world's most demanding technology organizations."
