TEMPE, Ariz. — (BUSINESS WIRE) — February 11, 2016 — Amkor Technology, Inc. (NASDAQ: AMKR), a leading provider of semiconductor packaging and test services, today announced financial results for the fourth quarter and full year ended December 31, 2015. The GAAP financial results for the fourth quarter of 2015 include certain one-time, non-cash accounting charges related to the increase in Amkor’s ownership interest in J-Devices Corporation to 100% on December 30, 2015. These charges were excluded from Amkor’s fourth quarter guidance and we believe the table “Non-GAAP Results” below provides a basis for comparing our 2015 operating results with our fourth quarter guidance and prior periods.

“Fourth quarter results were generally in line with expectations,” said Steve Kelley, Amkor’s president and chief executive officer. “Although 2015 was challenging, early in the year we reduced our capital and operational budgets, which allowed us to generate positive free cash flow for the year.”

“During 2015 we made strong progress in many of our key initiatives,” added Kelley. “Amkor’s advanced System-in-Package (SiP) business is gaining significant traction and achieved sales of $725 million. These multi-component, multi-function products demand a variety of high precision assembly technologies, which leverage Amkor’s strengths. Automotive was also a bright spot for Amkor as sales were up 10%. Finally, our Greater China Revenues grew 20% and we have significantly expanded the number of accounts we engage with in the region.”

* Fourth quarter and full year 2015 net income and earnings per diluted share exclude a gain of $16 million related to our previous investments in J-Devices and a non-cash loss of $30 million relating to the release of a foreign currency translation adjustment account, for a net loss of $14 million. Full year 2015 net income and earnings per diluted share exclude a charge of $9 million for the early extinguishment of debt related to the redemption of our 7.375% Senior Notes due 2018. Fourth quarter and full year 2014 gross margin exclude charges of $75 million and net income and earnings per diluted share exclude charges of $77 million and $78 million, net of tax, respectively, relating to the settlement of our litigation with Tessera. Full year 2014 net income and earnings per diluted share also exclude the gain on the sale of our subsidiary to J-Devices of $18 million, net of tax. The reconciliation to the comparable GAAP measures is included below under “Selected Operating Data.”

In December, Amkor increased its ownership in J-Devices Corporation from 66% to 100% through the exercise of existing options. J-Devices was formed in 2009 as a joint venture to acquire the assembly and test operations of Toshiba. Since that time, it has experienced considerable growth through a number of acquisitions involving other large semiconductor companies in Japan. J-Devices is now the largest outsourced semiconductor assembly and test (OSAT) provider in Japan and the sixth largest in the world. Using the latest wire bond assembly and test technologies, J-Devices specializes in producing high quality and reliable semiconductor packages for the exacting standards of the automotive end market.

“The purchase of the remaining interest in J-Devices has been part of our long term strategic plan to strengthen our relationships with the key semiconductor companies in Japan and enhance our position in the rapidly growing automotive market,” continued Kelley. “As a result, Amkor is now the world’s largest OSAT provider for automotive ICs, with around $750 million in combined automotive application revenue. We believe that consolidating J-Devices with Amkor will facilitate the acceleration of synergies and cost savings across the organization.”

Amkor has invested an aggregate of $202 million since 2009 to acquire its 100% interest in J-Devices, and this investment has generated $84 million of equity in earnings for Amkor through December 31, 2015. For the year ended December 31, 2015, J-Devices had revenues of $813 million, EBITDA of $114 million and net income of $30 million. Cash and cash equivalents were $128 million and total debt was $56 million for J-Devices at December 31, 2015. Amkor’s balance sheet at December 31, 2015 reflects the consolidation of J-Devices, and the operating results of J-Devices will be consolidated beginning in 2016. The reconciliation to the comparable GAAP measure for EBITDA is included below under "Selected Operating Data."

Cash and cash equivalents were $523 million, and total debt was $1.6 billion, at December 31, 2015.

Business Outlook

“Market conditions in Q1 remain sluggish, with particular weakness in the high-end smartphone market,” said Kelley. “Despite challenging market conditions, we expect that Q1 revenues will increase 21% sequentially, driven by incremental revenue from J-Devices. At this time, we expect full year 2016 capital expenditures of around $650 million.”

Based upon currently available information, we have the following expectations for the first quarter 2016, which will include J-Devices’ operating results:

• Net sales of $785 million to $835 million, up 17% to 25% from the prior quarter
• Gross margin of 9% to 13%
• Net loss of ($37) million to ($7) million, or ($0.15) to ($0.03) per diluted share

Selected Operating Data

In the press release above we provide non-GAAP net income and non-GAAP earnings per diluted share for the quarter and year ended December 31, 2015. We also provide non-GAAP gross margin, non-GAAP net income and non-GAAP earnings per diluted share for the quarter and year ended December 31, 2014. We present these non-GAAP amounts to demonstrate the impact of the consolidation of J-Devices, the sale of our subsidiary to J-Devices, the early extinguishment of debt and 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.

Selected Operating Data

In the press release above we provide EBITDA and Adjusted EBITDA, which are not defined by U.S. GAAP. We define EBITDA as net income before interest expense, income tax expense and depreciation and amortization. We believe EBITDA and Adjusted EBITDA to be relevant and useful information to our investors because they provide additional information in assessing our financial operating results. Our management uses EBITDA and Adjusted EBITDA in evaluating our operating performance, our ability to service debt and our ability to fund capital expenditures. However, EBITDA and Adjusted EBITDA have certain limitations in that they do 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 and Adjusted 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 and Adjusted EBITDA may not be comparable to similarly titled measures reported by other companies. Below is our reconciliation of EBITDA and Adjusted EBITDA to U.S. GAAP net income.

In the press release above we refer to free cash flow, which is not defined by U.S. GAAP. We define free cash flow as net cash provided by operating activities less payments for property, plant and equipment. 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. Below is our reconciliation of free cash flow to U.S. GAAP net cash provided by operating activities.

Forward-Looking Statement Disclaimer

This press release contains forward-looking statements within the meaning of federal securities laws. All statements other than statements of historical fact are considered forward-looking statements including, without limitation, statements regarding our gaining market share in Japan and enhancing our SiP business, position in the automotive market, realizing synergies and cost savings from the acquisition of J-Devices and all of the statements made under "Business Outlook" above. These forward-looking statements involve a number of risks, uncertainties, assumptions and other factors that could affect future results and cause actual results and events to differ materially from historical and expected results and those expressed or implied in the forward-looking statements, including, but not limited to, the following:

• there can be no assurance that our new factory and research and development center in Korea will be completed, or that the actual scope, costs, timeline or benefits of the project will be consistent with our current expectations;
• the highly unpredictable nature and cyclicality of the semiconductor industry;
• timing and volume of orders relative to production capacity and the inability to achieve high capacity utilization rates, control costs and improve profitability;
• volatility of consumer demand, double booking by customers and deterioration in forecasts from our customers for products incorporating our semiconductor packages, including any slowdown in demand or changes in customer forecasts for smartphones or other mobile devices and generally soft end market demand for electronic devices;
