CHANDLER, Ariz. — (BUSINESS WIRE) — July 28, 2014 — Amkor Technology, Inc. (NASDAQ: AMKR), a leading provider of semiconductor packaging and test services, today announced financial results for the second quarter ended June 30, 2014, with net sales of $767 million, net income of $50 million, and earnings per diluted share of $0.21. Net income includes a net gain of $18 million ($0.08 per diluted share) related to the sale of Amkor's Japanese subsidiary to J-Devices, Amkor's 60% owned joint venture in Japan.

“We delivered solid second quarter results that were consistent with our expectations,” said Steve Kelley, Amkor's president and chief executive officer. “Sales were up 10% sequentially and 3% year-over-year, with a corresponding improvement in our gross margin. We are poised to grow faster than the semiconductor industry in 2014 and improve our profitability.”

Selected financial information for the second quarter 2014 is as follows:

• Net Sales: $767 million, up 10% from $696 million in the prior quarter, and up 3% from $746 million in the second quarter of 2013
• Gross Margin: 19.6%, compared to 18.5% in the prior quarter, and 18.5% in the second quarter of 2013

Cash and cash equivalents were $526 million, and total debt was $1.5 billion, at June 30, 2014.

Business Outlook

“We expect record sales for the third quarter and a strong second half of 2014,” noted Kelley. “The launch of flagship mobile devices with high Amkor content is expected to drive third quarter growth of 9% to 15%, both sequentially and year-over-year, after normalizing for the sale of our Japanese subsidiary.”

“We see further, customer driven opportunities to grow our sales in the first half of 2015, and are increasing our full year 2014 capital expenditures to around $675 million to capture these opportunities. Nearly all of the incremental investment will be for advanced package capacity and leading-edge testers. The demand for this capacity is spread across many customers, and we believe that these investments are the foundation for our long-term growth,” continued Kelley.

Based upon currently available information, we have the following expectations for the third quarter 2014:

• Net sales of $815 million to $865 million, up 6% to 13% from both the prior quarter and year-over-year. After normalizing for the sales of our divested Japanese subsidiary, net sales are expected to increase 9% to 15% from both periods
• Gross margin of 20% to 22%
• Net income of $47 million to $70 million, or $0.20 to $0.29 per diluted share
• Full year 2014 capital expenditures of around $675 million
