                                Margins

SUNNYVALE, Calif.--(BUSINESS WIRE)--Oct. 27, 2008--Harmonic Inc. (NASDAQ: HLIT), a leading provider of broadcast and on-demand video delivery solutions, today announced its preliminary and unaudited results for the quarter ended September 26, 2008.

For the third quarter of 2008, the Company reported net sales of $91.5 million, up 11% from $82.3 million in the third quarter of 2007. For the first nine months of 2008, net sales were $268.1 million, up 20% from $223.8 million in the same period of 2007. International sales represented 39% of revenue for the third quarter of 2008, compared to 46% in the same period of 2007. In the third quarter of 2008, Harmonic had strong bookings across the Company's global customer base of cable, satellite, telco and other operators.

The Company maintained its gross margins in the third quarter of 2008, reflecting the continued success of its new products and solutions, as well as its sourcing strategy and product design innovations.

GAAP net income for the third quarter of 2008 was $12.0 million, or $0.12 per diluted share, up from $9.4 million, or $0.12 per diluted share, for the same period of 2007. The results for the third quarter of 2008 included a charge of approximately $0.8 million for the impairment of an investment in the unsecured debt of Lehman Brothers. Excluding this charge and non-cash accounting charges for stock-based compensation, the amortization of intangibles, excess facilities and a credit arising from the reversal of a valuation allowance against certain deferred tax assets, the non-GAAP net income for the third quarter of 2008 was $15.9 million, or $0.17 per diluted share, up from $11.9 million, or $0.15 per diluted share, for the same period of 2007. See "Use of Non-GAAP Financial Measures" and "GAAP to non-GAAP Reconciliation" below.

As of September 26, 2008, the Company had cash, cash equivalents and short-term investments of $293.4 million, up from $288.2 million as of June 27, 2008.

"We are pleased with our third quarter operating performance, bookings and momentum moving into the fourth quarter," said Patrick Harshman, President and Chief Executive Officer. "Across different markets and geographies, video service providers continue to select our award-winning systems and solutions to expand their on-demand, high-definition and next-generation IP-based service offerings."

"While the global economic environment creates uncertainty, we remain confident about our strong market position and long-term growth opportunities. Our technology leadership, diverse customer base and operating performance have placed us in an excellent position to further strengthen our competitive position and extend our global customer base."

Business Outlook

The Company anticipates that net sales for the fourth quarter of 2008 will be in a range of $92 to $95 million and gross margins will be 47% to 49% on a GAAP basis. Non-GAAP gross margins for the same period, excluding charges for stock-based compensation and the amortization of intangibles, are anticipated to be in a range of 49% to 51%.

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, which are non-cash or non-recurring in nature, 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 financial measures presented here are gross margin, operating expense, net income and net income per share. The presentation of non-GAAP information 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 the non-GAAP financial measures discussed in this press release to the most directly comparable GAAP financial measures 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 financial 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 charges and credits
         in operating expenses due to adjustments related to vacating
         portions of its Sunnyvale campus, estimating income from
         subleases of buildings, and to the closing of its
         manufacturing and research and development facilities in the
         UK. The Company excludes one-time charges and credits of this
         nature in evaluating its ongoing operational performance. We
         believe that these charges and credits 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

        The Company 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 companies.

     -- Amortization of Intangibles

        The Company has incurred amortization of intangibles related
         to acquisitions made by the Company. Management excludes
         these items when it evaluates its core operating performance.
         We believe that eliminating these expenses is useful to
         investors when comparing historical and prospective results
         and comparing such results to other companies because these
         expenses will vary if and when the Company makes additional
         acquisitions.

     -- Impairment of a Marketable Security

        The fair value of the Company's investment in the unsecured
         debt of Lehman Brothers Holdings, Inc. has been substantially
         reduced because of the bankruptcy of the issuer. As a result,
         we recorded an "other-than-temporary" impairment charge to
         reduce the carrying value of this investment. This impairment
         charge has been excluded from our non-GAAP net income because
         we expect the impairment charge to be a non-recurring item.
         As such, we believe that its inclusion in our calculation of
         non-GAAP net income would not provide a meaningful comparison
         of current versus prior net income.

     -- Reversal of Valuation Allowance for Certain Deferred Tax
         Assets

        The Company has reversed a valuation allowance against certain
         deferred tax assets, resulting in a credit to its provision
         for income taxes. Management has excluded the discrete
         benefit from this reversal from its calculation of the
         Company's non-GAAP net income because it believes that it is
         of a one-time nature and does not reflect future expected tax
         provisions nor does it provide a meaningful comparison of
         current versus prior net income.
