©2013 Amkor Technology, Inc.Amkor Confidential Information14Financial Reconciliation TablesWe define free cash flow as net cash provided by operating activities less purchases of property, plant and equipment.  Free cashflow is not defined by U.S. generally accepted accounting principles ("U.S. GAAP").  However, we believe free cash flow to berelevant and useful information to our investors because it provides them with additional information in assessing our liquidity, capitalresources and financial operating results.  Our management uses free cash flow in evaluating our liquidity, our ability to service debtand our ability to fund capital additions.  However, free cash flow has certain limitations, including that it does not represent theresidual cash flow available for discretionary expenditures since other, non-discretionary expenditures, such as mandatory debtservice, are not deducted from the measure.  The amount of mandatory versus discretionary expenditures can vary significantlybetween periods.  This measure should be considered in addition to, and not as a substitute for, or superior to, other measures ofliquidity 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.We define EBIT as net income before interest expense and income tax expense. We define EBITDA as EBIT before depreciationand amortization. EBIT and EBITDA are not defined by U.S. GAAP. However, we believe EBIT and EBITDA to be relevant anduseful information to our investors because they provide investors with additional information in assessing our financial operatingresults. Our management uses EBIT and EBITDA in evaluating our operating performance, our ability to service debt and our abilityto fund capital additions. However, these measures 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, and ourdefinitions of EBIT and EBITDA may not be comparable to similarly titled measures reported by other companies.We define return on invested capital ("ROIC") as net operating profit after tax (the sum of operating income plus equity in earnings ofunconsolidated affiliate less income tax expense) divided by average invested capital (the sum of average debt plus average equityless average cash).  ROIC is not defined by U.S. GAAP.  However, we believe ROIC is relevant and useful information for ourinvestors and management in evaluating whether our capital investments are generating stockholder value. 

©2013 Amkor Technology, Inc.Amkor Confidential InformationIn this presentation we provide adjusted gross margin, adjusted net income, adjusted earnings per diluted share and adjusted EBITDA for the quarter and year ended December 31,2012, and the twelve months ended March 31, 2013.  We present these non-GAAP amounts to demonstrate the impact of the loss contingency we recognized for the quarter and yearended December 31, 2012, and the twelve months ended March 31, 2013, 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 thecalculation 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 haverecognized.  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 andearnings per diluted share prepared in accordance with U.S. GAAP.  Above is the reconciliation of adjusted gross margin, adjusted net income and adjusted earnings per diluted share toU.S. GAAP gross margin, net income and earnings per diluted share.15Financial Reconciliation Tables(1)See discussion of Non-GAAP measures on page 204Q122012LTM 1Q13Gross Margin16%15%16%Plus:  Loss Contingency Charge Divided by Net Sales2%2%1%Adjusted Gross Margin18%17%17%Net Income  $7$42$43Plus:  Loss Contingency Charge, Net of Tax205252Adjusted Net Income$27$94$95Earnings per Diluted share$0.05$0.24$0.23Plus:  Loss Contingency Charge per Diluted Share0.080.210.21Adjusted Earnings per Diluted Share$0.13$0.45$0.44EBITDA(1)$139$527$542Plus:  Cost of Goods Sold Portion of Loss Contingency Charge205050Adjusted EBITDA(1)$159$577$592($ in millions)($ in millions)

CHANDLER, Ariz. – May 15, 2013 — Amkor Technology, Inc. (NASDAQ:AMKR) today announced that it intends to offer, subject to market and other conditions, $200 million aggregate principal amount of 6.375% Senior Notes due 2022 (the “Notes”). The Notes are to be offered in a private placement in the United States to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”) and to non-U.S. persons outside the United States pursuant to Regulation S under the Securities Act.
The Notes will be unsecured, and the offering price will be determined by negotiations between the company and the initial purchasers. The Notes will be issued as additional notes under an indenture dated as of September 21, 2012 pursuant to which Amkor previously issued $300.0 million aggregate principal amount of 6.375% Senior Notes due 2022 (the “Existing Notes”). The Notes will rank equally with and form a part of a single class of securities with the Existing Notes.
We expect to use the net proceeds of the Notes offering for general corporate purposes, which may include, among other things, capital additions, acquisitions and other investments.
This announcement does not constitute an offer to sell or a solicitation of an offer to buy any of the Notes, nor shall there be any offer, solicitation or sale in any state or jurisdiction in which such an offer, solicitation or sale would be unlawful.
The Notes have not been registered under the Securities Act or any state securities laws and may not be offered or sold in the United States absent registration or an applicable exemption from such registration requirements.
