CHANDLER, Ariz.--(BUSINESS WIRE)--Feb. 13, 2013-- Amkor Technology, Inc. (NASDAQ: AMKR), a leading provider of semiconductor packaging and test services, today announced financial results for the fourth quarter ended December 31, 2012, with net sales of $723 million, net income of $27 million, and earnings per diluted share of $0.13. For the full year 2012, Amkor reported net sales of $2.76 billion, adjusted net income of $95 million and adjusted earnings per diluted share of $0.46.

“We are pleased with our fourth quarter results and improvements over the prior quarters of 2012 and the fourth quarter of 2011,” said Ken Joyce, Amkor's president and chief executive officer. “Bolstered by solid sales growth in mobile communications, results for the quarter came in at the higher end of our expectations. Our investments in support of the communications end market are paying off and continue to gain momentum. Driven by notable strength in smartphones and tablets, our communications revenue grew 12% and represented nearly 50% of our total sales in 2012.”

Selected financial information for the fourth quarter 2012 is as follows:

• Net Sales: $723 million, up 4% from $695 million in the prior quarter, and up 6% from $684 million in the fourth quarter of 2011
• Gross Margin: 18%, compared to 17% in the prior quarter, and 16% in the fourth quarter of 2011
• Net Income: $27 million, up from $22 million in the prior quarter, and up from $25 million in the fourth quarter of 2011
• Earnings Per Diluted Share: $0.13, up from $0.11 in the prior quarter, and up from $0.11 in the fourth quarter of 2011

Selected financial information for the full year 2012 is as follows:

• Net Sales: $2.76 billion, down 1% from $2.78 billion in 2011
• Adjusted Gross Margin: 17%, compared to 18% in 2011
• Adjusted Net Income: $95 million, up 3% from $92 million in 2011
• Adjusted Earnings Per Diluted Share: $0.46, up 18% from $0.39 in 2011

The adjusted gross margin, adjusted net income and adjusted earnings per diluted share presented above for the full year 2012 exclude a loss contingency we recognized in the second quarter of 2012 of $34 million ($33 million, net of tax) relating to our pending patent license arbitration with Tessera, Inc. and are non-GAAP measures. Selected operating data for the fourth quarter and full year 2012, and a reconciliation of the full year 2012 non-GAAP measures presented above to the comparable GAAP measures, are included in a section below before the financial statements.

“Capital additions were $86 million during the fourth quarter and $533 million for the full year 2012, primarily in support of customers in smartphones and tablets,” said Joanne Solomon, Amkor's executive vice president and chief financial officer. “We accelerated the purchase of certain packaging and test equipment to meet demand for communications during the quarter.”

Cash and cash equivalents were $413 million, and net debt was $1.1 billion, at December 31, 2012.

Business Outlook

“Looking ahead to the first quarter 2013, we are seeing seasonal demand patterns with revenues expected to be down 5% to 11% from the fourth quarter 2012,” said Joyce. “We are currently planning capital additions of around $450 million for 2013 primarily to support the growth opportunities we see in mobile communications. We are also planning an additional $150 million of spending for the acquisition of land and construction relating to our previously announced new factory and R&D center in South Korea.”

Based upon currently available information, we have the following expectations for the first quarter 2013:

• Net sales of $640 million to $690 million, down 5% to 11% from the prior quarter
• Gross margin of 14% to 17%
• Net loss of $5 million to net income of $16 million, or ($0.03) to $0.09 per diluted share
• Capital additions of around $125 million

*We define return on invested capital ("ROIC") as net operating profit after tax (the sum of operating income plus equity in earnings of unconsolidated affiliate less income tax expense) divided by average invested capital (the sum of average debt plus average equity less average cash). ROIC is not defined by U.S. generally accepted accounting principles ("U.S. GAAP"). However, we believe ROIC is relevant and useful information for our investors and management in evaluating whether our capital investments are generating stockholder 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 U.S. 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, free cash flow has certain limitations, including that it does not represent the residual cash flow available for discretionary expenditures since other, non-discretionary expenditures, such as mandatory debt service, are not deducted from the measure. The amount of mandatory versus discretionary expenditures can vary significantly between periods. This measure should be considered in addition to, and not as a substitute for, or superior to, other measures of liquidity or financial performance prepared in accordance with U.S. GAAP, such as net cash provided by operating activities. Furthermore, our definition of free cash flow may not be comparable to similarly titled measures reported by other companies.

**Amkor's Board of Directors previously authorized $300 million for the repurchase of our common stock. During 2012, we repurchased 16.5 million shares for a purchase price of $79.5 million. Since inception of the program, we have repurchased a total of 45.0 million shares at an aggregate purchase price of $208.4 million.

In the press release above we provide adjusted gross margin, adjusted net income and adjusted earnings per diluted share for the year ended December 31, 2012. We present these non-GAAP amounts to demonstrate the impact of the loss contingency we recognized for the year ended December 31, 2012 related to our pending patent license arbitration with Tessera, Inc. However, these measures have limitations, including that they exclude the charges for the Tessera arbitration award, which is an amount that the company may ultimately have to pay in cash. Furthermore, the factors affecting the calculation of the arbitration award are complex and subject to determination by the arbitration panel. Therefore, the final amount of the loss may be more than the amount we have recognized. Accordingly, these measures that exclude the loss contingency should be considered in addition to, and not as a substitute for, or superior to, gross margin, net income and earnings per diluted share prepared in accordance with U.S. GAAP. Below is the reconciliation of adjusted gross margin, adjusted net income and adjusted earnings per diluted share to U.S. GAAP gross margin, net income and earnings per diluted share.
