2 ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS. In May 2000 we completed our purchase of ASI's three remaining packaging and test factories, known as K1, K2 and K3 for a purchase price of $950.0 million and made an equity investment in ASI of $309.0 million of the total of $459.0 million we committed to invest at that time. On June 30, 2000 we made an investment in ASI of $30.0 million, which represented the second installment of the $459.0 million we committed to invest. We expect to complete the remaining $120.0 million equity investment in two installments in August and October of 2000. ITEM 7. FINANCIAL STATEMENTS AND EXHIBITS. On May 12, 2000, we filed a current report on Form 8-K related to the acquisition and investment mentioned in Item 2, which incorporated by reference historical and pro forma financial information as of and for the year ended December 31, 1999. On June 19, 2000, we filed a current report on Form 8-K related to the acquisition and investment, which included pro forma financial information as of and for the three months ended March 31, 2000. Filed herein is pro forma financial information as of and for the three months ended March 31, 2000 and for the year ended December 31, 1999.

3 UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL DATA OF AMKOR AS OF AND FOR THE THREE MONTHS ENDED MARCH 31, 2000 The unaudited pro forma consolidated balance sheet as of March 31, 2000 appearing below gives effect to the following transactions as if they had occurred on March 31, 2000: - our $410.0 million private placement of our common stock; - our incurrence of $750.0 million of new secured bank debt; - our acquisition of K1, K2 and K3 for $950.0 million; - our $459.0 million equity investment in ASI of which $309.0 was made in May 2000, $30.0 million was made in June 2000 and the remaining $120.0 million is expected to be made in two equal installments by August 31, 2000 and October 31, 2000; - ASI's use of the net proceeds from its sale of K1, K2 and K3 and our investment, principally to repay outstanding debt; and - the expected conversion of 150 billion Korean won (approximately $132 million) of ASI's debt to equity by ASI's creditor banks. 136 billion Korean won was converted as of May 2000 with the balance expected to be converted by October 31, 2000. The unaudited pro forma consolidated income statement gives effect to the above transactions and the following transaction for the three months ended March 31, 2000 appearing below as if they occurred on January 1, 1999: - our sale of $258.75 million of 5% Convertible Subordinated Notes due 2007. The unaudited pro forma consolidated financial information appearing below is not necessarily indicative of the results of operations and financial condition that we would have achieved if the transactions described above had actually been consummated on such dates, nor are they necessarily indicative of the future results and financial condition we will achieve. Accordingly, our future results and financial condition could vary significantly from the unaudited pro forma consolidated financial information appearing below. We have used the purchase method of accounting in accordance with APB Opinion No. 16 "Business Combinations" to prepare the accompanying unaudited pro forma consolidated financial information. Under this method of accounting, we allocated the $950.0 million aggregate purchase price of K1, K2 and K3, to specific assets acquired based on their estimated fair values. The purchase price does not include the estimated $30.9 million transaction fees and expenses incurred in connection with our acquisition of K1, K2 and K3 and the related financing. The balance of the purchase price for K1, K2 and K3 represents the excess of cost over net assets acquired. We have estimated the preliminary fair value of K1, K2 and K3 assets based primarily on our knowledge of this business and on information furnished by ASI. We will determine the final allocation of the purchase price based upon the receipt of an appraisal. Accordingly, we may not finalize purchase accounting adjustments for up to one year after the closing of our acquisition of K1, K2 and K3. We have used the equity method of accounting in accordance with APB Opinion No. 18 to prepare the accompanying unaudited pro forma financial information to give effect to our investment in ASI. Under this method of accounting, our investment in ASI is carried at cost plus or minus our equity in all increases or decreases in the investee's net assets after the date of investment. Under the equity method, net income and stockholders' equity of the investor should be the same as if the investor fully consolidated the investee. Accordingly, we have included in the unaudited pro forma consolidated income statement for the three months ended March 31, 2000 the equity in the income (loss)

4 of ASI, including amortization of the excess of the cost of our investment over the underlying equity in the net assets. We have prepared the unaudited pro forma consolidated financial information in accordance with U.S. GAAP. These principles require us to make extensive use of estimates and assumptions that affect: (1) the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and (2) the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

14 UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL DATA OF AMKOR AS OF AND FOR THE YEAR ENDED DECEMBER 31, 1999 The unaudited pro forma consolidated income statement gives effect to the following transactions as if they occurred on January 1, 1999: - our 410.0 million private placement of our common stock; - our incurrence of $750.0 million of new secured bank debt; - our acquisition of K1, K2 and K3 for $950.0 million; - our $459.0 million equity investment in ASI; - ASI's use of the net proceeds from its sale of K1, K2 and K3 and our investment, principally to repay outstanding debt; - the conversion of 150 billion Korean won(approximately $132 million) of ASI's debt to equity by ASI's creditor banks; and - our sale of $258.75 million of 5% Convertible Subordinated Notes due 2007. - our acquisition of K4 in May 1999 for $582.0 million and our incurrence of $625.0 million of long-term debt in connection with that acquisition; - our 50 billion Korean won(approximately $41.6 million) equity investment in ASI in October 1999; - the conversion of 98 billion Korean won (approximately $82 million) of ASI's debt into equity by ASI's creditor banks in October 1999; and - ASI's use of the net proceeds from its sale of K4, principally to repay outstanding debt. The unaudited pro forma consolidated financial information appearing below is not necessarily indicative of the results of operations and financial condition that we would have achieved if the transactions described above had actually been consummated on such dates, nor are they necessarily indicative of the future results and financial condition we will achieve. Accordingly, our future results and financial condition could vary significantly from the unaudited pro forma consolidated financial information appearing below. We have used the purchase method of accounting in accordance with APB Opinion No. 16 "Business Combinations" to prepare the accompanying unaudited pro forma consolidated financial information. Under this method of accounting, we allocated (1) the $575.0 million aggregate purchase price of K4, plus $7.0 million of assumed employee benefit liabilities, and (2) the $950.0 million aggregate purchase price of K1, K2 and K3, to specific assets acquired based on their estimated fair values. The purchase price does not include the estimated $30.9 million transaction fees and expenses incurred in connection with our acquisition of K1, K2 and K3 and the related financing. The balance of the purchase price for K1, K2 and K3 represents the excess of cost over net assets acquired. We have estimated the preliminary fair value of K1, K2 and K3 assets based primarily on our knowledge of this business and on information furnished by ASI. We will determine the final allocation of the purchase price based upon the receipt of an appraisal. Accordingly, we may not finalize purchase accounting adjustments for up to one year after the closing of our acquisition of K1, K2 and K3. We have used the equity method of accounting in accordance with APB Opinion No. 18 to prepare the accompanying unaudited pro forma financial information to give effect to our investment in ASI. Under this method of accounting, our investment in ASI is carried at cost plus or minus our equity in

15 all increases or decreases in the investee's net assets after the date of investment. Under the equity method, net income and stockholders' equity of the investor should be the same as if the investor fully consolidated the investee. Accordingly, we have included in the unaudited pro forma consolidated income statement for the year ended December 31, 1999 the equity in the loss of ASI, including amortization of the excess of the cost of our investment over the underlying equity in the net assets. We have prepared the unaudited pro forma consolidated financial information in accordance with U.S. GAAP. These principles require us to make extensive use of estimates and assumptions that affect: (1) the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and (2) the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.
