Harmonic Announces Third Quarter Results; Year-over-year Sales Increase 20%; New Products to Help Shape the Future of Video Services

October 20, 2005

SUNNYVALE, Calif.--(BUSINESS WIRE)--Oct. 20, 2005--Harmonic Inc. (Nasdaq:HLIT), a leading provider of digital video, broadband optical networking and IP delivery systems, today announced its results for the quarter ended September 30, 2005. For the third quarter of 2005, the Company reported net sales of $61.0 million, up 20% from $50.6 million in the third quarter of 2004 and up 2% from $59.8 million in the second quarter of 2005. International sales represented 44% of total sales for the third quarter of 2005, compared to 59% in the same period of 2004 and 41% in the second quarter of 2005.

The Company's Convergent Systems division (CS), which designs, manufactures and markets digital headend systems for a number of markets, had divisional net sales of $35.8 million in the third quarter of 2005, compared to $34.6 million in the same period of 2004 and $43.0 million in the second quarter of 2005. The sequential decline in CS net sales was primarily the result of reduced orders in recent months from a major cable customer, offset in part by orders from another major customer for a number of significant digital simulcast projects in the third quarter. The Broadband Access Networks division (BAN), which designs, manufactures and markets fiber optic products primarily for broadband cable networks, had divisional net sales of $25.2 million in the third quarter of 2005, up 58% from $16.0 million in the same period of 2004 and 51% from $16.8 million in the second quarter of 2005. The increase in BAN sales reflects increased shipments to a large domestic telco customer for its fiber-to-the-premises (FTTP) project and to cable customers in international markets.

For the third quarter of 2005, the Company reported lower gross margins due primarily to the significant sales of FTTP products, which carry margins that are substantially lower than our average product margins. In addition, the Company recorded a $1.6 million charge for excess inventory, reflecting rapid product transitions in certain CS product lines.

The GAAP net loss for the third quarter of 2005 was $2.9 million, or $0.04 per share, compared to a GAAP net loss of $4.2 million, or $0.06 per share, for the same period of 2004. Excluding the effect of non-cash accounting charges for the amortization of intangibles, the non-GAAP net loss for the third quarter of 2005 was $2.6 million, or $0.04 per share, compared to a non-GAAP net loss of $2.0 million, or $0.03 per share, for the same period of 2004. As of September 30, 2005, the Company had cash, cash equivalents and short-term investments of $104.9 million.

The Company expects fourth quarter net sales to be comparable to net sales for the third quarter. While this guidance includes continuing shipments from current backlog of FTTP products to a large domestic telco customer in the fourth quarter, the Company currently does not expect to make significant shipments of products to this customer in 2006.

"During the third quarter, we continued to roll out important new technology and win new orders for digital headend and fiber optic systems across different markets," said Anthony J. Ley, Chairman, President and Chief Executive Officer. "We believe our exciting new product introductions at the International Broadcasting Convention, such as the Electra 5000 and MV 3500 encoders, will help shape the future of video, providing a variety of different operators with the ability to offer multi-service, multi-network, multi-channel and multi-resolution video to a growing array of endpoints, including TVs, PCs and mobile devices."

"During the third quarter, we continued to extend our customer base in Europe and Latin America. We also saw another major domestic cable company begin to deploy our systems for digital simulcasting at a number of sites and expect other cable operators to implement similar architectures in coming periods. While still very early in the rollout of video services by telco operators, we continued to ship our digital systems to more international customers for video-over-DSL, extending our worldwide base to over 25 telco customers. As we move into 2006, our satellite customers appear to be very impressed with our new encoders and are working closely with us in their planned migration to new compression technology and expansion of their high-definition channel offering."

Harmonic will also host a conference call today to discuss its financial results at 2:00 P.M. Pacific (5:00 P.M. Eastern).
