Harmonic Announces First Quarter Results

Continued Success of New Products;
Strengthening of Technology Leadership

SUNNYVALE, Calif.¾April 25, 2007¾Harmonic Inc. (NASDAQ: HLIT), a leading provider of broadcast and on-demand video delivery solutions, today announced its preliminary results for the quarter ended March 30, 2007.

For the first quarter of 2007, the Company reported net sales of $70.2 million, up 25% from $56.2 million in the first quarter of 2006. During the first quarter of 2007, the Company experienced continued strong demand from its domestic cable customers, as well as penetration of new telco and satellite customers worldwide. International sales represented 40% of net sales for the first quarter of 2007, compared to 54% in the same period of 2006 and 41% in the fourth quarter of 2006.

Gross margins in the first quarter of 2007 were significantly higher than in the same period of 2006 due to more favorable gross margins from the sale of new products and increased manufacturing volumes. However, gross margins for the quarter were lower than anticipated as a result of an unusually high proportion of edge and access product revenue, which carries lower margins than other product lines. Edge and access products, video processing products and software and services represented 51%, 37% and 12% of revenue, respectively, in the first quarter. Because orders for video processing products exceeded those of edge and access products in the first quarter, the Company anticipates improved gross margins in coming periods.

In addition to its previously announced decision to discontinue a product line and shut down its manufacturing operations in the UK, the Company decided to close its remaining research and development activities in the UK in order to further reduce operating expenses. As a result, the Company incurred a charge of $1.8 million in the first quarter related to severance costs, excess facilities charges and remaining inventories.

GAAP net income for the first quarter of 2007 was $1.0 million, or $0.01 per diluted share, compared to a GAAP net loss of $5.1 million, or $0.07 per share, for the same period of 2006. Excluding the charge and accounting charges for stock-based compensation expense and the amortization of intangibles, the non-GAAP net income for the first quarter of 2007 was $5.3 million, or $0.07 per diluted share, compared to a non-GAAP net loss of $3.3 million, or $0.04 per share, for the same period of 2006. See “GAAP to non-GAAP Income/(Loss) Reconciliation” below for further information on the Company’s non-GAAP measures.

As of March 30, 2007, the Company had cash, cash equivalents and short-term investments of $82.9 million, compared to $92.4 million at the end of 2006. During the first quarter of 2007, the Company utilized its cash resources to increase inventories for some of its newest products and to reduce by $2.4 million pre-merger liabilities related to its DiviCom acquisition in 2000.

“We are pleased with our solid sales performance in the first quarter of 2007, which is typically the slowest period of the year,” said Patrick Harshman, President and Chief Executive Officer. “During the quarter, we saw increased shipments to domestic cable customers for our video-on-demand edge and optical access products, as well as substantial orders for our new high-definition and standard-definition encoders and stream processing solutions. While our product mix led to reduced margins in the first quarter, we expect gross margins to improve in coming periods, as we continue to move forward on a number of significant video processing deployments.”

“Our powerful MPEG-4 AVC and MPEG-2 high-definition video encoding products continue to win in competitive evaluations, reinforcing our leadership in the IPTV market and helping us regain our

leadership position with satellite operators both domestically and internationally. We have also continued to extend our technology leadership with the recent introduction of a number of exciting new software solutions. These include significant enhancements to our suite of on-demand solutions, which is generating growing interest among a variety of operators. While it remains difficult to predict the timing of customer deployments, particularly in the emerging IPTV market, we are very encouraged by the success of our new products, the continued expansion of our customer base and the promising opportunities for growth in 2007 and beyond.”

Business Outlook

The Company anticipates combined net sales for the second and third quarters of 2007 to be in a range of $140 to 150 million and gross margins to be 44% to 45% on a non-GAAP basis, excluding stock-based compensation expense and the amortization of intangibles. GAAP gross margins for the same period are anticipated to be in a range of 42% to 43%.

Use of Non-GAAP Financial Measures

In establishing operating budgets, managing its business performance, and setting internal measurement targets, the Company excludes a number of items required by GAAP. Management believes that these accounting charges and credits, most of which are non-cash or non-recurring in nature or affect the period-to-period comparability of results, are not useful in managing its operations and business. Historically, the Company has also publicly presented these supplemental non-GAAP measures in order to assist the investment community to see the Company “through the eyes of management,” and thereby enhance understanding of its operating performance. The non-GAAP measures presented here are gross margins, operating expense, net income/(loss) and net income/(loss) per share. The presentation of non-GAAP information is subject to material limitations, is not intended to be considered in isolation or as a substitute for results prepared in accordance with GAAP and is not necessarily comparable to non-GAAP results published by other companies. A reconciliation of non-GAAP net income/(loss) to GAAP net income/(loss) is included with the financial statements contained in this press release. The non-GAAP adjustments described below have historically been excluded from our non-GAAP measures. These adjustments, and the basis for excluding them, are:

•

Restructuring Activities

–

Severance Costs

The Company has incurred severance costs in cost of sales and in operating expenses in connection with the closing of its manufacturing and research and development facilities in the UK. The Company excludes one-time costs of this nature in evaluating its ongoing operational performance. We believe that these costs do not reflect expected future expenses nor do they provide a meaningful comparison of current versus prior operating results.

–

Excess Facilities

The Company has incurred excess facilities costs in operating expenses due to the closing of its manufacturing and research and development facilities in the UK. The Company excludes one-time costs of this nature in evaluating its ongoing operational performance. We believe that these costs do not reflect expected future expenses nor do they provide a meaningful comparison of current versus prior operating results.

–

Product Discontinuance

In connection with the restructuring of its operations in the UK, the Company recorded charges for excess inventory in connection with discontinued products. The Company excludes one-time costs of this nature in evaluating its ongoing operational performance. We believe that these costs do not reflect expected future expenses nor do they provide a meaningful comparison of current versus prior operating results.

•

Non-Cash Items

	–		Stock-Based Compensation Expense

			Harmonic has incurred stock-based compensation expense in cost of sales and operating expenses as required under FAS 123R. The Company excludes stock-based compensation expense because it believes that this measure is not relevant in evaluating its core operating performance, either for internal measurement purposes or for period-to-period comparisons and benchmarking against other public companies.

	–		Impairment and Amortization of Intangibles

			The Company has incurred amortization of intangibles, included in gross margins and operating expenses, related to acquisitions. Management excludes these items when it evaluates its core operating performance. We believe that eliminating this expense is useful to investors when comparing historical and prospective results and comparing such results to other public companies since the amortization of intangibles will vary if and when the Company makes additional acquisitions.
