(NASDAQ: SILC),a leading provider of networking and data infrastructure solutions, today announced a design win with a Tier-1 global cyber securityleader, which has selected a range of Silicom-designed white-label switches as the networking infrastructure for its security platforms.Silicom engineered the full switch range to meet the customer's exact specifications, leveraging its existing switching building blocksand deep domain know-how to deliver a tailored solution within the customer's demanding timeline. Samples of the full product range havealready been delivered to the customer, and first production orders are expected to be fulfilled during 2026. After full ramp-up, annualsales are expected to reach approximately $5 million. Furthermore, discussions are already underway regarding higher-end white-labelswitches for the customer's next-generation systems — an opportunity that has the potential to significantly increase the white-labelswitch revenues from this account.Seeking to move away from vendor lock-in, the customer replaced itsexisting proprietary switches from an incumbent industry leader with Silicom's open, white-label solutions. The customer selected Silicomfollowing a rigorous evaluation process, citing Silicom’s engineering depth, its ability to deliver a complete and validated switchrange to specification, and its reputation as a reliable, long-term hardware partner. This strategic design win establishes white-labelswitching as Silicom’s newest product line, broadening a portfolio that already features industry-leading server adapters, FPGAsmart cards and Edge systems.“Being chosen by a global cyber security leader of this caliberto design and supply its entire switch family is a strong testament to the trust our customers place in Silicom,” commented LironEizenman, Silicom’s CEO. “We are proud to have delivered a complete, validated switch range that meets this demanding customer’sexact specifications — to the highest quality standards and on schedule. This is precisely the kind of meaningful, incremental winthat strengthens our revenue base and confirms the value of our broad engineering capabilities.”Mr. Eizenman continued, “This win also demonstrates our abilityto expand our partnerships into new product areas, responding to customer needs with speed and precision. The samples we have alreadydelivered across the full switch range speak for themselves — and with first production orders expected to be delivered during 2026,this relationship is moving forward rapidly. Importantly, we view this as just the first step into a broader market. We are already inactive discussions with other potential customers for our white-label switching solutions, marking a powerful entry into a space wherewe see meaningful opportunity ahead.”*** About SilicomSilicom Ltd. is an industry-leading provider of high-performance networkingand data infrastructure solutions.
