Third Quarter Highlights

• Net sales $734 million
• Gross margin 17.2%
• Net income $28 million
• Earnings per diluted share $0.12

TEMPE, Ariz. — (BUSINESS WIRE) — October 26, 2015 — Amkor Technology, Inc. (NASDAQ: AMKR), a leading provider of semiconductor packaging and test services, today announced financial results for the third quarter ended September 30, 2015.

"Third quarter revenues were at the higher end of our expectations and roughly flat to Q2,” said Steve Kelley, Amkor's president and chief executive officer. “Third quarter profit exceeded expectations, largely due to favorable exchange rates and a richer mix of assembly and test services."

*Second quarter 2015 results include a $9 million ($0.04 per diluted share) charge for the early extinguishment of debt related to the redemption of all $345 million aggregate principal amount of Amkor's outstanding 7.375% Senior Notes due 2018.

Cash and cash equivalents were $430 million, and total debt was $1.4 billion, at September 30, 2015.

Business Outlook

“In response to the generally soft end market demand for electronic devices, we expect customers to cautiously manage inventories through the fourth quarter of 2015,” said Kelley. “We are tightly controlling capital expenditures and working capital in line with the demand environment. Accordingly, we are reducing our estimate of full year 2015 capital expenditures from around $550 million to around $525 million, including around $150 million of spending for our new K5 facility."

Based upon currently available information, we have the following expectations for the fourth quarter 2015:

• Net sales of $660 million to $710 million, down 3% to 10% from the prior quarter
• Gross margin of 13% to 17%
• Net loss of $4 million to net income of $12 million, or ($0.02) to $0.05 per share
