Press Release

SAN JOSE, CA -- (Marketwired) -- 10/08/15 -- Harmonic Inc. (NASDAQ: HLIT), the worldwide leader in video delivery infrastructure, today announced updated guidance for the third quarter of 2015.

For the third quarter of 2015, the Company anticipates:

• Net revenue in the range of $81 million to $84 million
• GAAP gross margins in the range of 53.5% to 55.0%
• GAAP operating expenses in the range of $51.5 million to $53 million
• Non-GAAP gross margins in the range of 54.5% to 56.0%
• Non-GAAP operating expenses in the range of $46.5 million to $48 million

See "Use of Non-GAAP Financial Measures" and "GAAP to Non-GAAP Reconciliations" below.

Bookings for the third quarter of 2015 are anticipated to be in the range of $74 million to $75 million.

The updated guidance is based on preliminary results and remains subject to change in connection with the preparation of the unaudited financial statements for the quarter ended October 2, 2015.

"We faced a more challenging spending environment than expected in the quarter, resulting in updated financial guidance," said Patrick Harshman, Harmonic's CEO. "Several market factors continue to hamper near-term customer investment decisions; service provider consolidation, particularly within the U.S. and EMEA regions, and the pending release of our new cable edge architecture in mid-2016 amplified the effect. Although we anticipate these dynamics to extend into the fourth quarter of 2015, our value proposition is resonating strongly with both new and existing customers, our leadership position in the markets we address is intact, and we are confident in the strategic direction of the company."

The Company will release its unaudited third quarter 2015 financial results after the market close on Tuesday, October 27, 2015. Harmonic will also host a conference call that day at 2:00 p.m. Pacific (5:00 p.m. Eastern) to discuss these financial results and its outlook for the fourth quarter of 2015.

Use of Non-GAAP Financial Measures

In establishing operating budgets, managing its business performance, and setting internal measurement targets, we exclude 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, 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 profit, operating expenses, income (loss) from operations and net income (loss) (including those amounts as a percentage of revenue), and net income (loss) per diluted 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 historical non-GAAP financial measures discussed in this press release to the most directly comparable historical GAAP financial measures is included with the financial statements provided with this press release. The non-GAAP adjustments described below have historically been excluded from our GAAP financial measures. These adjustments are restructuring and related charges, impairment of long-term investment and non-cash items, such as stock-based compensation expense, amortization of intangibles, and adjustments that normalize the tax rate. The effects of stock-based compensation expense specific to common stock options are directly impacted by unpredictable fluctuations in our stock price. We expect the variability of the above charges to have a significant impact on our GAAP financial results.
