Interim Financial Statements

Interim Financial Statements

Basis of Presentation. The Consolidated Financial Statements and related disclosures as of March 31, 2021, and for the three months ended March 31, 2021 and 2020, are unaudited, pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”). The December 31, 2020 Consolidated Balance Sheet data was derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America (“U.S.”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations. In our opinion, these financial statements include all adjustments (consisting only of normal recurring adjustments) necessary for the fair statement of the results for the interim periods. These financial statements should be read in conjunction with the financial statements included in our Annual Report for the year ended December 31, 2020, filed on Form 10-K with the SEC on February 19, 2021. The results of operations for the three months ended March 31, 2021 are not necessarily indicative of the results to be expected for the full year. Unless the context otherwise requires, all references to “Amkor,” “we,” “us” or “our” are to Amkor Technology, Inc. and our subsidiaries. Certain prior year amounts have been reclassified to conform to current year presentation.

Use of Estimates. The Consolidated Financial Statements have been prepared in conformity with U.S. GAAP, using management’s best estimates and judgments where appropriate. These estimates and judgments affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. The estimates and judgments will also affect the reported amounts for certain revenues and expenses during the reporting period. Actual results could differ materially from these estimates and judgments, including the impact of Covid-19 and any worsening of the global business and economic environment.

Goodwill. The balance of goodwill in our Consolidated Balance Sheets reflects adjustments for foreign currency translation.

Unbilled Receivables. Total unbilled receivables as of March 31, 2021 and December 31, 2020 were $142.7 million and $146.8 million, respectively.

Contract Liability. Contract liabilities were $53.3 million and $51.6 million as of March 31, 2021 and December 31, 2020, respectively. As of March 31, 2021 and December 31, 2020, the short-term portion of the liability was $34.9 million and $30.3 million, respectively. Revenue recognized during the three months ended March 31, 2021 and 2020 that was included in the contract liability balance at the beginning of the period was $8.1 million and $5.3 million, respectively.
