FOR IMMEDIATE RELEASE

SILICOM ANNOUNCES DESIGN WIN FOR 100G

BYPASS BLADES WITH EXISTING CUSTOMER

- Customer Continues to Rely on Silicom as it Moves into the 100GB Arena -

KFAR SAVA, Israel— August 4, 2015, - Silicom Ltd. (NASDAQ and TASE: SILC) today announced a Design Win for 100G Bypass Blades with an existing customer in the Traffic Management industry. Initial-quantity production has begun and is expected to ramp up to approximately $1 million per year.

“We are very pleased that this customer, with whom we have been working closely for a long time, is turning to us now to help them take their product portfolio into the 100G environment,” commented Shaike Orbach, Silicom’s President and CEO. “The continued development of our relationship with the customer, which has led to this Design Win, confirms the quality of our Bypass technologies as well as our correct and timely read of the market, which is now beginning to progress towards 100G.”

Mr. Orbach continued, “In fact, with the 100G market moving toward mainstream deployments, we believe that revenues from this Design Win will grow beyond the currently-forecast $1 million per year, and that our strong 100G capabilities will become an increasingly strategic advantage, contributing significantly to our ability to achieve our long-term growth targets.”

Silicom’s Bypass switches are fail-safe mechanisms that assure the continued flow of traffic in high-traffic in-line appliances in times of failure, whether due to loss of power, software malfunction or other occurrence.
