Harmonic Announces Second Quarter Results; Increasing Sales and New Optical and Digital Products

July 22, 2004

SUNNYVALE, Calif.--(BUSINESS WIRE)--July 22, 2004--Harmonic Inc. (Nasdaq:HLIT) today announced its results for the quarter ended July 2, 2004.

For the second quarter of 2004, the Company reported net sales of $57.0 million, up from $55.1 million in the previous quarter and up from $41.7 million in the second quarter of 2003. The revenue growth reflects increased shipments to cable and satellite customers worldwide. International sales represented 44% of total sales for the second quarter of 2004, up from 33% in the previous quarter, due principally to the completion of initial customer acceptance testing for a large international project.

The Company's CS division, which designs, manufactures and markets digital headend systems for a number of markets, had divisional net sales of $33.3 million in the second quarter of 2004, up from $27.1 million in the same period of 2003. The BAN division, which designs, manufactures and markets fiber optic products primarily for broadband cable networks, had divisional net sales of $23.7 million in the second quarter of 2004, up from $14.6 million in the same period of 2003.

"We are pleased with our sales growth, our improved results from operations and our introduction of exciting new products in the second quarter," said Anthony J. Ley, Chairman, President and Chief Executive Officer. "We saw increasing demand from our international and domestic cable customers who continue to deploy more equipment to offer video-on-demand, high-definition (HD) programming, new digital channels, cable telephony and IP services. We continued to extend our technology leadership with the introduction of new digital encoders and optical transmission systems, including the initial deployments of our new Commercial Services Solution to enable cable operators to provide broadband services to businesses, schools and government offices."

"Our satellite customers continue to expand the number of HD and digital channels, and a number of telephone companies are exploring different approaches to offer competitive digital video services. Across our different markets, we are helping customers in their plans to migrate to next-generation network transmission and video compression technologies. While the timing of customer deployments remains difficult to predict, we expect that intensifying competition among our customers, along with the ever-increasing bandwidth and technical requirements for new services, will continue to drive growing demand for our fiber optic and digital products in the second half of 2004 and beyond."

The GAAP net loss for the second quarter of 2004 was $1.8 million, or $0.02 per share, compared to a net loss of $11.7 million, or $0.19 per share, for the same period of 2003. The GAAP results for the second quarter include a credit relating to the sale of previously reserved inventory of $1.2 million. Excluding the inventory benefit described above and the effects of non-cash accounting charges for the amortization of intangibles, the non-GAAP net income for the second quarter of 2004 was $0.5 million, or $0.01 per share. This compares to a non-GAAP net loss of $6.6 million, or $0.11 per share, for the same period of 2003.

At the end of the second quarter of 2004, the Company had cash, cash equivalents and short-term investments of $92.2 million, compared to $108.4 million at the end of the first quarter. The decline in the cash position primarily reflected increases in working capital requirements, particularly in receivables, as well as approximately $4.8 million paid under a tax-sharing agreement from an acquisition completed in 2000.

Harmonic's conference call regarding its second quarter 2004 results will be held today, July 22, 2004, at 2:00 p.m. Pacific (5:00 p.m. Eastern).
