FOR IMMEDIATE RELEASE

Silicom Updates Second Quarter 2015 Financial Outlook

- Q2 2015 Financial Results and Conference Call Scheduled for

Wednesday, July 22, 2015 –

KFAR SAVA, Israel – July 6, 2015 - Silicom Ltd. (NASDAQ and TASE: SILC), an industry-leading provider of high-performance server/appliances networking solutions, announced that its second quarter revenues are projected to be in the range of $16.8 million to $17.2 million, below the Company’s previous projections. Based on current demand and the schedule of new customer product launches, the company projects that its third quarter revenues will range from $18 million to $19 million, representing both sequential and year-over-year growth.

Mr. Shaike Orbach, Silicom’s President and CEO, commented, “Our shortfall for the second quarter reflects a softening of demand from some of our customers, due to longer-than-expected decision making processes together with the slower market deployment of our high-potential design wins and our new solutions for upcoming industry trends. We expect that the second quarter will be the low-point of our revenues for the year and believe that the strategy that has worked extremely well for us for many years will continue to prove itself in the future.”

Silicom will release its second quarter 2015 results on Wednesday, July 22, 2015. The Company will also host a conference call on the same day at 9:00am Eastern Time. On the call, management will review and discuss the results and will be available to answer investors’ questions.
