Fourth Quarter 2010

• Net sales $751 million

• Gross margin 21%

• Net income $51 million

• Earnings per diluted share $0.20

Full Year 2010

• Net sales $2.94 billion

• Gross margin 23%

• Net income $232 million

• Earnings per diluted share $0.91

CHANDLER, Ariz. — February 9, 2011 —Amkor Technology, Inc. (NASDAQ: AMKR), a leading provider of semiconductor assembly and test services, today announced financial results for the fourth quarter ended December 31, 2010, with net sales of $751 million, net income of $51 million, and earnings per diluted share of $0.20. For the full year 2010, Amkor reported net sales of $2.94 billion, net income of $232 million, and earnings per diluted share of $0.91.

“We delivered record net sales and net income for the full year 2010,” said Ken Joyce, Amkor’s president and chief executive officer. “Strong demand across all of our package families and end markets, particularly in our core markets for wireless communications, gaming and other consumer electronics, drove net sales growth of 35% and a 49% increase in net income. We also reduced our net debt by $79 million and delivered a 24% return on invested capital.”

“During the fourth quarter we saw solid growth in communications, a seasonal decline in gaming and inventory adjustments by some of our customers in the consumer electronics and networking areas,” said Joyce. “The lower business volumes in the quarter, along with unfavorable foreign currency exchange rate movements, reduced our gross margin from the prior quarter.”

Selected financial information for the fourth quarter 2010 is as follows:

• Net Sales: $751 million, down 5% from $794 million in the prior quarter, and up 12% from $668 million in the fourth quarter of 2009

• Gross Margin: 21%, compared to 24% in the prior quarter and 26% in the fourth quarter of 2009

• Net Income: $51 million, down from $78 million in the prior quarter, and down from $88 million in the fourth quarter of 2009

• Earnings Per Diluted Share: $0.20, down from $0.30 in the prior quarter, and down from $0.33 in the fourth quarter of 2009

Selected financial information for the full year 2010 is as follows:

• Net Sales: $2.94 billion, up 35% from $2.18 billion in 2009

• Gross Margin: 23%, compared to 22% in 2009

• Net Income: $232 million, up 49% from $156 million in 2009

• Earnings Per Diluted Share: $0.91, up from $0.67 in 2009

“Our fourth quarter earnings per diluted share were adversely impacted by approximately $0.04 as a result of unfavorable foreign currency exchange rate movements and $0.02 for an unanticipated reserve for foreign taxes,” said Joanne Solomon, Amkor’s executive vice president and chief financial officer. “Capital additions were $103 million during the fourth quarter, primarily in support of solid demand for wireless communications.”

Cash and cash equivalents were $405 million, and net debt was $959 million, at December 31, 2010. In January 2011, the company redeemed all $100 million of its 6.25% Convertible Subordinated Notes due 2013. The Notes were converted into 13.4 million shares of Amkor Common Stock and no cash was used for the redemption. As a consequence of this conversion, net debt would have been $859 million.

Selected operating data for the fourth quarter and full year 2010 are included in a section before the financial statements.

Business Outlook

“Looking ahead to the first quarter of 2011, our strong position in gaming is amplifying typical seasonal patterns and we see some carryover of the inventory adjustments that began in the fourth quarter,” said Joyce. “The corresponding decline in utilization is expected to compress our gross margin in the first quarter.”

“As we exit the first quarter, we are anticipating a rebound in customer demand and a year of solid growth driven primarily by strength in wireless communications and consumer electronics,” continued Joyce. “To meet the capacity requirements of our leading customers, we are currently planning capital additions of approximately $500 million for 2011, with spending weighted in the first half of the year to take advantage of the growth opportunities we see in the second quarter and the balance of the year.”

Based upon the currently available information, we have the following expectations for the first quarter of 2011:

• Net sales of $660 million to $690 million, down 8% to down 12% from the prior quarter

• Gross margin between 16% and 19%

• Net income of $10 million to $35 million, or $0.05 to $0.14 per diluted share

• Capital additions of approximately $135 million for the first quarter, and capital additions of approximately $500 million for the full year

^* Return on invested capital (“ROIC”) is defined as net operating profit after tax divided by average invested capital (the sum of average debt plus average equity minus average cash). ROIC is not defined by generally accepted accounting principles (“GAAP”). We believe that ROIC is useful information for our investors in evaluating whether our capital investments are generating shareholder value.

We define free cash flow as net cash provided by operating activities less purchases of property, plant and equipment. Free cash flow is not defined by GAAP. However, we believe free cash flow to be relevant and useful information to our investors because it provides them with additional information in assessing our liquidity, capital resources and financial operating results. Our management uses free cash flow in evaluating our liquidity, our ability to service debt and our ability to fund capital additions.

However, these measures should be considered in addition to, and not as a substitute for, or superior to, other measures of financial performance prepared in accordance with GAAP, and our definitions of ROIC and free cash flow may not be comparable to similarly titled measures reported by other companies.
