Amkor Technology Reports Financial Results for the Fourth Quarter and Full Year 2014

Record 2014 Sales $3.13 Billion ----- GAAP EPS $0.55, Non-GAAP EPS $0.88

TEMPE, Ariz.-- Amkor Technology, Inc. (AMKR), a leading provider of semiconductor packaging and test services, today announced financial results for the fourth quarter and full year ended December 31, 2014.

“We delivered a strong finish to the year with fourth quarter operating results well above the high end of our guidance," said Steve Kelley, Amkor's president and chief executive officer. "Driven by notable strength in mobile communications using our advanced packaging and test technologies, we saw record sales for the quarter and full year, and a substantial improvement in profitability. And over the last two years, net sales have grown 13% to more than $3.13 billion and our non-GAAP earnings per share have nearly doubled. These results demonstrate that our strategic initiatives are gaining traction, and we anticipate another year of sales and earnings growth in 2015."

The gross margin, net income and earnings per diluted share information presented above under Non-GAAP Results excludes charges relating to the settlement of our litigation with Tessera and are non-GAAP measures. The charges are $89 million ($78 million, net of tax) in 2014 and $11 million ($10 million, net of tax) in 2013. The reconciliation to the comparable GAAP measures is included below under "Selected Operating Data."

Cash and cash equivalents were $450 million, and total debt was $1.5 billion, at December 31, 2014.

Business Outlook

"We expect that first quarter 2015 revenues will be up 6% year-on-year and down 13% sequentially," said Kelley. "We also expect full year 2015 capital expenditures of around $600 million, including around $150 million of spending for our new K5 factory and R&D center in Incheon, Korea."

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

• Net sales of $715 million to $765 million, down 10% to 16% from the prior quarter
• Gross margin of 16% to 19%
• Net income of $10 million to $34 million, or $0.04 to $0.14 per diluted share

About Amkor

Amkor is a leading provider of semiconductor packaging and test services to semiconductor companies and electronics OEMs. More information about Amkor is available from the company's filings with the Securities and Exchange Commission and at Amkor's website: www.amkor.com.

In the press release above we provide non-GAAP gross margin, non-GAAP net income, and non-GAAP earnings per diluted share for the years ended December 31, 2014 and 2013, respectively. We also provide non-GAAP gross margin, non-GAAP net income and non-GAAP earnings per diluted share for the quarter ended December 31, 2014. We present these non-GAAP amounts to demonstrate the impact of the charges we recognized related to the settlement of our litigation with Tessera. Generally, a non-GAAP financial measure is a numerical measure of a company’s performance, financial position or cash flows that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with U.S. generally accepted accounting principles ("U.S. GAAP"). These measures have limitations, including that they exclude the charges for the settlement payments, which are amounts that the company will ultimately have to pay in cash, and 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 non-GAAP gross margin, non-GAAP net income and non-GAAP earnings per diluted share to U.S. GAAP gross margin, net income and earnings per diluted share.

Note to unaudited consolidated financial statements:

In January 2015, Amkor entered into a settlement agreement with Tessera to resolve their outstanding litigation. Under the terms of the settlement, Amkor agreed to pay Tessera a total of $155 million in equal quarterly installments of $9.6875 million over the next four years in exchange for a mutual release and dismissal of all claims relating to their pending litigation and arbitration proceedings. As a result of the settlement, Amkor recorded the net present value of the settlement obligation ($137 million), less the previously accrued expense ($50 million), as a charge allocated between cost of sales ($75 million) and interest expense ($12 million). The remaining amount of the gross settlement charge ($18 million) will be accreted through interest expense over the four year term of the arrangement to reflect the impact of the time value of money due to the long term nature of the obligation and related payment terms. The settlement liability has been recorded in accrued expenses (current) and other long-term liabilities (non-current) for the present value of payments due within one year and those due in excess of one year, respectively.
