TEL AVIV, Israel--(BUSINESS WIRE)--April 11, 2001

Ceragon Networks Ltd. (Nasdaq:CRNT), a global provider of high-capacity broadband wireless systems for next generation communications networks, today announced that the company's first quarter financial results will be reported on April 23, 2001.

At present, Ceragon expects first quarter revenues of approximately $12.6 million, excluding first quarter shipments to a U.S. Wireless competitive local exchange carrier (CLEC), which recently announced its intention to halt new network build out and reduce capital expenditures due to current uncertainty of collection. Ceragon expects to record a first quarter pro forma EPS loss of $0.09 to $0.08 with outstanding accounts receivable to this customer of $2.6 million.

If first quarter shipments to this customer are included in revenues, then first quarter revenues would be $16.3 million, with pro forma EPS between a loss of $0.01 to $0.00 with outstanding accounts receivable to this customer of $6.3 million.

Pro forma EPS excludes the effect of non-cash based deferred compensation and one time charges.

With respect to a second U.S. customer, Advanced Radio Telecom (Nasdaq:ARTT), which recently announced its intention to file a petition for protection under Chapter 11 of the U.S. bankruptcy laws, Ceragon announced that it has financial exposure to ART of up to approximately $100,000.

In addition, certain U.S. CLECs recently postponed delivery of equipment under previously issued purchase orders, resulting in a significantly reduced backlog.

"Ceragon is a strong company with solid foundations," said Shraga Katz, president and CEO, Ceragon Networks Ltd. "Our global presence demonstrates our commitment to customer diversification. With extensive deployments that span over 25 countries worldwide, we are confident that our strategy will serve as an anchor in this turbulent market. The company is closely monitoring the U.S. wireless CLEC market and is taking appropriate measures to adjust our operations accordingly."

A summary of the measures the company is taking and guidance on future financial performance will be provided during the company's quarterly conference call on April 23, 2001.

The company plans to issue a press release announcing its results at approximately 4:00 p.m. EST on Monday, April 23, 2001. A conference call will follow, beginning at 5:00 p.m. EST hosted by Shraga Katz, president and CEO, Ceragon Networks Ltd., and Shimon Gal, CFO, Ceragon Networks Ltd.
