Amkor Technology Reports Financial Results for the Fourth Quarter and Full Year 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, 2013, with net sales of $755 million, net income of $41 million and earnings per diluted share of $0.18. For the full year 2013, Amkor reported net sales of $2.96 billion, net income of $109 million and earnings per diluted share of $0.50.

"2013 was a very good year for Amkor," said Steve Kelley, Amkor's president and chief executive officer. "Revenues grew by 7% to nearly $3 billion, a new record for the company. Gross margin improved by 160 basis points, and earnings per share increased 20%."

Selected financial information for the fourth quarter 2013 is as follows:

• Net sales: $755 million, down 2% from $768 million in the prior quarter, and up 4% from $723 million in the fourth quarter of 2012
• Gross margin of 19.9%, compared to adjusted gross margin of 19.7% in the prior quarter, and adjusted gross margin of 18.4% in the fourth quarter of 2012
• Net income of $41 million, compared to adjusted net income of $35 million in the prior quarter, and adjusted net income of $27 million in the fourth quarter of 2012
• Earnings per diluted share of $0.18, compared to adjusted earnings per diluted share of $0.15 in the prior quarter, and adjusted earnings per diluted share of $0.13 in the fourth quarter of 2012

Selected financial information for the full year 2013 is as follows:

• Net sales: $2.96 billion, up 7% from $2.76 billion in 2012
• Adjusted gross margin: 18.8%, compared to 17.2% in 2012
• Adjusted net income: $119 million, compared to $94 million in 2012
• Adjusted earnings per diluted share: $0.54, compared to $0.45 in 2012

The adjusted gross margin, adjusted net income and adjusted earnings per diluted share information presented above excludes loss contingency charges relating to our pending patent license litigation and are non-GAAP measures. The loss contingency charges are $56 million ($52 million, net of tax) in 2012 and $11 million ($10 million, net of tax) in 2013. Selected operating data for all periods discussed above, and a reconciliation to the comparable GAAP measures, are included in a section below before the financial statements.

"We delivered solid fourth quarter results with sales at the mid-point of our guidance, and gross margin and earnings per share at the high end," said Joanne Solomon, Amkor's executive vice president and chief financial officer. "Sales were down 2% sequentially as we saw the expected seasonal declines in the consumer and computing markets. Gross margin of 19.9% was consistent with the third quarter."

Cash and cash equivalents were $610 million, and total debt was $1.7 billion, at December 31, 2013.

Business Outlook

"Historically, the first quarter is our weakest quarter of the year, and 2014 fits that pattern," said Kelley. "We expect that first quarter revenues will be down 11% sequentially, mostly due to seasonality, but also because of continuing weakness in the high-end of the mobile device market. For the full year, we see sequential growth in the second quarter, followed by a strong second half tied to the launch of flagship mobile devices."

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

• Net sales of $650 million to $700 million, down 7% to 14% from the prior quarter
• Gross margin of 14% to 17%
• Net income of ($5 million) to $17 million, or ($0.02) per basic share to $0.08 per diluted share
• Full year 2014 capital expenditures of around $450 million

***We define EBITDA as net income attributable to Amkor before interest expense, income tax expense, depreciation and amortization. EBITDA is not defined by U.S. generally accepted accounting principles ("U.S. GAAP"). We believe EBITDA to be relevant and useful information to our investors because it provides them with additional information in assessing our financial operating results. Our management uses EBITDA in evaluating our operating performance, our ability to service debt and our ability to fund capital expenditures. However, EBITDA has certain limitations in that it does not reflect the impact of certain expenses on our consolidated statements of income, including interest expense, which is a necessary element of our costs because we have borrowed money in order to finance our operations, income tax expense, which is a necessary element of our costs because taxes are imposed by law, and depreciation and amortization, which is a necessary element of our costs because we use capital assets to generate income. EBITDA should be considered in addition to, and not as a substitute for, or superior to, operating income, net income or other measures of financial performance prepared in accordance with U.S. GAAP. Furthermore our definition of EBITDA may not be comparable to similarly titled measures reported by other companies.

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. 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 expenditures. 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.

In the press release above we provide adjusted gross margin, adjusted net income, adjusted earnings per diluted share and adjusted EBITDA for the years ended December 31, 2013 and 2012, respectively. We also provide adjusted gross margin, adjusted net income and adjusted earnings per diluted share for the quarters ended December 31, 2013 and 2012, respectively, and for the quarter ended September 30, 2013. We present these non-GAAP amounts to demonstrate the impact of the loss contingency we recognized for these periods, related to our pending patent license litigation. However, these measures have limitations, including that they exclude the charges accrued for the patent license litigation, which is an amount that the company may ultimately have to pay in cash. Furthermore, the factors affecting the calculation of the potential damages for the patent license litigation are complex and subject to determination by the arbitration panel and the courts. Therefore, the final amount of the loss may be more or less 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, operating income, 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 along with a reconciliation of EBITDA to adjusted EBITDA.
