Press Release

SAN JOSE, Calif., July 14, 2014 (GLOBE NEWSWIRE) -- Harmonic Inc. (Nasdaq:HLIT), the worldwide leader in video delivery infrastructure, announced today its preliminary results for the second quarter of 2014.

Net revenue for the second quarter of 2014 is expected to be in the range of $108.0 million to $110.0 million, compared with the Company's previous guidance of $113.0 million to $123.0 million. GAAP gross margin is expected to be in the range of 44.5% to 46.5%, compared with the Company's previous guidance of 49.5% to 50.5%. GAAP operating expenses are expected to be in the range of $58.5 million to $59.5 million, compared with the Company's previous guidance of $61.0 million to $62.0 million. Non-GAAP gross margin is expected to be in the range of 49.0% to 51.0%, compared with the Company's previous guidance of 52.5% to 53.5%. Non-GAAP operating expenses are expected to be in the range of $52.5 million to $53.5 million, compared with the Company's previous guidance of $54.5 million to $55.5 million. Non-GAAP net income per diluted share for the second quarter of 2014 is expected to be in the range of $0.00 to $0.02.

Preliminary bookings for the second quarter of 2014 were $113.4 million, with first half 2014 bookings approximately 1% higher than bookings in the first half of 2013.

Total backlog and deferred revenue was $132.1 million as of June 27, 2014, compared to $126.4 million as of March 29, 2014.

Total cash, cash equivalents and short-term investments are expected to be in the range of $133.0 million to $135.0 million at the end of the second quarter 2014. In the second quarter of 2014, the Company used approximately $25.7 million to repurchase approximately 3.6 million shares of common stock under its share repurchase program.

"We are disappointed in our second quarter results," said Patrick Harshman, President and Chief Executive Officer. "We saw a global slowdown in our video business as several of our larger customers began planning for our new virtualized approaches for delivering video services. This video slowdown was particularly pronounced among EMEA and North American Broadcast and Media customers, where we also saw several anticipated projects delayed and growing consideration of the new Ultra HD format and new HEVC compression technology."

"Our North America Cable business performed better, as strong demand for our cable edge products continued, including for the NSG Pro platform released last year. Looking ahead, while the transitioning video market is turbulent and we are consequently cautious about our near-term results, the growing signs of coming video technology investment cycles and our cable customers' continuing positive response to our CCAP products are encouraging. We therefore remain positioned and focused on achieving the company's overarching objectives for driving sustainable top and bottom line growth."

Business Outlook

For the third quarter of 2014, Harmonic anticipates:

• Net revenue in the range of $103.0 million to $113.0 million
• GAAP gross margins in the range of 48.0% to 49.0%
• GAAP operating expenses in the range of $57.5 million to $58.5 million
• Non-GAAP gross margins in the range of 52.0% to 53.0%
• Non-GAAP operating expenses in the range of $51.5 million to $52.5 million

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

As Harmonic has not yet completed its quarter-end fiscal close for its second quarter ended June 27, 2014, or its analysis of the quarter, the results presented in this press release are estimated and preliminary and, therefore, may change. The Company plans to report its complete unaudited GAAP and Non-GAAP results on July 28, 2014.

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 margin, operating expenses, income (loss) from operations and net income (loss) 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. The non-GAAP adjustments described below have historically been excluded from our GAAP financial measures. These adjustments are restructuring and related charges and non-cash items, such as stock-based compensation expense, amortization of intangibles, and adjustments that normalize the tax rate. With respect to our expectations under "Business Outlook" above, reconciliation of non-GAAP guidance measures to corresponding GAAP measures is not available without unreasonable efforts on a forward-looking basis due to the high variability and low visibility with respect to the charges which are excluded from these non-GAAP measures. 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.
