Comments of Management

Commenting on the results, Shaike Orbach, Silicom’s President and CEO, said, “Q4 was a breakthrough quarter that capped off our best year on record, demonstrating the power of the ‘Silicom Formula for Growth’ to drive our sales, profits and margins to ever higher levels.”

Mr. Orbach continued, “Our record of growing the Company by 50% quarter after quarter confirms our ability to create essential products for some of IT’s hottest Big-Data-driven markets, including SDN, virtualization and cloud computing. With over 90 OEM customers, including most of the market leaders, we have become the ‘de facto’ standard for OEMs in these sectors, all of whom are looking for a performance boost and an ‘edge’ for their server-based offerings.

“For example, during the quarter we launched an innovative offload product line based on the Intel® Communications Chipset, a solution that addresses one of the virtualized data center’s major pain points and that is already under evaluation by several key virtualized cloud market players. In addition, we achieved our first major Design Win with a leading storage virtualization player, positioning Silicom as a one-stop-shop provider for virtualized data centers with a comprehensive offering for this exploding market. We believe these developments indicate the potential scale of our Cloud business model and its power to become one of Silicom’s major new growth drivers.”

Mr. Orbach concluded, “With continued success in the markets that have driven us to this point and exciting new markets ahead, we believe Silicom is positioned for continued faster-than-market growth. We consider our Q4 and 2013 results a validation of our strong positive momentum and the growth opportunities before us. With a firm base, significant growth engines, a healthy pipeline of opportunities and new market trends working in our favor, we are on track with our plans to continue scaling the business.”
