Cash and cash investments at the end of the quarter were $98.3 million.
“The revenue growth resumed in Q3 and accelerated in Q4,” said Ira Palti, President
and CEO of Ceragon. “We expect this momentum to continue during 2010, driven primarily
by ongoing demand for high capacity backhaul for cellular networks. Geographically, we
expect continued strength in Asia Pacific, augmented by improvement in most other regions.

Increasingly, wireless carriers of all types are expecting backhaul vendors to deliver a
complete network including a host of professional services. We will continue to invest, as we
did in Q4, in more R&D, pre-sales, sales as well as services resources, particularly in North
America, to accommodate the trend toward more turnkey projects. With continued strong
focus on expense control, we expect profits to grow more rapidly than revenues, with a target
of 30-35% revenue growth for 2010 over 2009.”
