Non-GAAP gross margin was 61 percent, compared with 63 percent in the prior fiscal year. Non-GAAP net income was $1.2 million, compared with a non-GAAP net loss of $0.4 million in fiscal 2013.

Adjusted EBITDA¹ for fiscal 2014 was $4.0 million, compared with $2.4 million in fiscal 2013.

“We had a tremendous fiscal 2014, one that exceeded all of our initial guidance expectations and generated the highest ever quarter and annual non-GAAP profitability and Adjusted EBITDA. With the strong momentum in our business, I have never been more positive about the future prospects for the Company,” said Dr. Avi Katz, Chairman and Chief Executive Officer of GigOptix, Inc.

“For the last two years, we executed on several initiatives to redefine our business and enhance efficiencies in all our product offerings while continuing to invest heavily in innovation. Through our product development efforts, and swift commercialization, we substantiated our strong position in all markets of our activities, especially in the fast-growing 40Gbps and 100Gbps High-Speed Communications market. For example, our datacom product shipments in fiscal 2014 grew nearly 80 percent from the prior year. In addition, our total product revenue in 2014 increased 20 percent annually from 2013,” said Dr. Katz. “We also maintained our dominant position in sales of coherent 100Gbps telecom products, while continuously extending our product offerings to cover all required terrestrial Long-Haul and Metro limiting and linear products. These products are also extendable for use in the upcoming 400Gbps generation that customers are currently sampling. Also, in the RF market, we nearly doubled our annual revenue in the emerging high-speed point-to-point backhaul E-band market in fiscal 2014, and launched our development toward the next generation of V-Band products. In summary, I also want to highlight the consistent and highly profitable nature of our Industrial ASIC product line, which delivered annual revenue growth of 18 percent over 2013.

“We view 2014 as a real inflection point in the Company’s history. We have fully integrated and consolidated all the technologies and assets we acquired since the Company’s inception, structured the Company in an efficient manner, and experienced a meaningful improvement in our financial and business performance. We are confident about our ability to continue these positive trends and enhance shareholder value through 2015 and the years to follow,” said Dr. Katz.

Financial Outlook

“After a positive fiscal 2014, we enter fiscal 2015 with a strong foundation to continue our growth trajectory. We currently believe first quarter revenue will be approximately $8.5 million to $8.7 million. This would represent an improvement of approximately 15 percent to 18 percent above the $7.4 million we recorded in the first quarter of fiscal 2014, and a small decline compared with the fourth quarter, which is milder than the normal first quarter seasonal trend that impacts the High-Speed Communications business every year.” said Darren Ma, Vice President and Chief Financial Officer of GigOptix, Inc. “For fiscal 2015, it is our current expectation that we will continue to see double digit revenue growth for the third consecutive year. As of now, being in the early stage of the fiscal year, and with the Lunar New Year later this month, we still have some limited visibility to the full year outlook. With these factors in mind, we currently project revenue to be approximately $37 million to $38 million, or growing about 14 percent over the prior year.”
