NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Interim Financial Statements

Basis of Presentation. The Consolidated Financial Statements and related disclosures as of March 31, 2020, and for the three months ended March 31, 2020 and 2019, are unaudited, pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”). The December 31, 2019 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, 2019, filed on Form 10-K with the SEC on February 19, 2020. The results of operations for the three months ended March 31, 2020 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,” “our” or the “company” 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, 2020 and December 31, 2019 were $131.3 million and $125.4 million, respectively.

2. Net Sales by Product Group and End Market

Other	(256		)	(488		)
Other (income) expense, net	$	(2,315	)	$	(4,565	)

4. Income Taxes

Income tax expense of $4.8 million for the three months ended March 31, 2020 reflects income taxes, foreign withholding taxes and minimum taxes.

ASC 740 generally requires we provide for income taxes during interim periods based on the estimated annual effective tax rate (“AETR”) for the full year. For the three months ended March 31, 2020, we have excluded a jurisdiction from the AETR calculation and used a discrete method to calculate the income tax provision for that jurisdiction. We believe inclusion of this jurisdiction in the AETR calculation is impractical at this time given that normal deviations in the projected pre-tax net income (loss) would result in a disproportionate and unreliable annual effective tax rate under the AETR method.

We monitor on an ongoing basis our ability to utilize our deferred tax assets and whether there is a need for a related valuation allowance. In evaluating our ability to recover our deferred tax assets in the jurisdictions from which they arise, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies and results of recent operations.

We maintain a valuation allowance on certain U.S. and foreign deferred tax assets. Such valuation allowances are released as the related tax benefits are realized or when sufficient evidence exists to conclude that it is more likely than not that the deferred tax assets will be realized.

Unrecognized tax benefits represent reserves for potential tax deficiencies or reductions in tax benefits that could result from federal, state or foreign tax audits. Gross unrecognized tax benefits decreased from $26.2 million at December 31, 2019 to $23.1 million as of March 31, 2020, primarily due to the lapse of statutes of limitations in foreign jurisdictions. All of our unrecognized tax benefits would reduce our effective tax rate if recognized. Our unrecognized tax benefits are subject to change for effective settlement of examinations, changes in the recognition threshold of tax positions, the expiration of statutes of limitations and other factors.

We have tax returns that are open to examination in various jurisdictions for tax years 2012-2019. The open years contain matters that could be subject to differing interpretations of applicable tax laws and regulations related to the amount and/or timing of income, deductions and tax credits. There can be no assurance that the outcome of the examinations will be favorable. In certain circumstances where we elect to appeal the results of an examination, we may be required to make tax assessment payments to proceed with the administrative appeal process.

5. Earnings Per Share

Basic earnings per share (“EPS”) is computed by dividing net income attributable to Amkor common stockholders by the weighted-average number of common shares outstanding during the period. The weighted-average number of common shares outstanding is reduced for treasury stock.

Diluted EPS is computed based on the weighted-average number of common shares outstanding plus the effect of dilutive potential common shares outstanding during the period. Dilutive potential common shares include outstanding stock options and unvested restricted shares.

The following table summarizes the computation of basic and diluted EPS:



	For the Three Months Ended March 31,
	2020		2019
	(In thousands, except per share data)
Net income (loss) attributable to Amkor common stockholders	$	63,889	$	(22,879	)

Weighted-average number of common shares outstanding - basic	240,919		239,414
Effect of dilutive securities:
Stock options and restricted share awards	414		—
Weighted-average number of common shares outstanding - diluted	241,333		239,414
Net income (loss) attributable to Amkor per common share:
Basic	$	0.27	$	(0.10	)
Diluted	0.26		(0.10		)

The following table summarizes the potential shares of common stock that were excluded from diluted EPS because the effect of including these potential shares was anti-dilutive:



	For the Three Months Ended March 31,
	2020	2019
	(In thousands)
Stock options and restricted share awards	4,321	7,123

(1)	Amounts reclassified out of accumulated other comprehensive income (loss) are included as a component of net periodic pension cost (Note 12) or other (income) expense, net.

7. Investments

We classify our short-term investments in fixed income securities as available-for-sale debt investments, except for one foreign government security classified as held-to-maturity. The held-to-maturity debt security matured in the first quarter ended March 31, 2020. All of our available-for-sale debt investments as of March 31, 2020 will be available to fund current operations and are recorded at fair value (Note 13). Unrealized gains and losses on our available-for-sale debt investments are included as a separate component of accumulated other comprehensive income (loss), net of tax. Realized gains and losses on our available-for-sale debt investments and declines in value judged to be an impairment are included in other (income) expense, net. The cost of short-term investments matured or sold is based on the average cost method.

In determining if and when a decline in value below the adjusted cost of our available-for-sale debt investments is an impairment, we evaluate on an ongoing basis the market conditions, trends of earnings, financial condition, credit ratings, any underlying collateral and other key measures for our short-term investments. An impairment is considered if (i) we have the intent to sell the security, (ii) it is more likely than not that we will be required to sell the security before recovery of the entire amortized cost basis or (iii) we do not expect to recover the entire amortized cost basis of the security. If impairment is considered on condition (i) or (ii) above, the entire difference between the amortized cost and the fair value

of the debt security is recognized in earnings. If an impairment is considered based on condition (iii), the amount representing credit losses will be recognized in earnings and as an allowance for credit losses, and the amount relating to all other factors will be recognized in other comprehensive income.

(1)	All unrealized losses have been in a continuous loss position for less than 12 months. We do not intend to sell the investments in an unrealized loss position, and it is not more likely than not that we will be required to sell these investments before recovery of their amortized cost bases.


(2)	We have available-for-sale debt investments of $6.1 million with contractual maturities from 1 year to 5 years. Expected maturities can differ from contractual maturities because the issuers may have the right to call or prepay obligations without call or prepayment penalties, and we view our available-for-sale debt investments as available for current operations.


(3)	In April 2020, we increased our available-for-sale debt investments by $130.0 million.

The following table summarizes our debt investments as of December 31, 2019:

The cash equivalent money market funds (Level 1) at December 31, 2019 have been corrected to include $286.7 million of cash equivalents that were excluded in previously reported amounts. There was no change to total cash and cash equivalents reported on our consolidated balance sheet. We determined this was immaterial to the prior period but have presented the balance as revised for comparability.


(2)	The fair market value of the security is $6.3 million. The carrying value of the security represents the amortized cost.

8. Factoring of Accounts Receivable

For certain accounts receivable, we use non-recourse factoring arrangements with third-party financial institutions to manage our working capital and cash flows. Under this program, we sell receivables to a financial institution for cash at a discount to the face amount. As part of the factoring arrangements, we perform certain collection and administrative functions for the receivables sold.

(6)

In July 2018, our subsidiary, Amkor Technology Singapore Holding Pte, Ltd., entered into a $250.0 million senior secured revolving credit facility, which is guaranteed by Amkor Technology, Inc. The availability for our revolving credit facility is based on the amount of eligible accounts receivable. Principal is payable at maturity. Interest is payable monthly at LIBOR plus 1.25% to 1.75% (2.85% as of March 31, 2020). As of March 31, 2020, $100.0 million was available to be drawn.

Defined contribution expense	$	4,816	$	4,405

13. Fair Value Measurements

The accounting framework for determining fair value includes a hierarchy for ranking the quality and reliability of the information used to measure fair value, which enables the reader of the financial statements to assess the inputs used to develop those measurements. The fair value hierarchy consists of three tiers as follows: Level 1, defined as quoted market prices in active markets for identical assets or liabilities; Level 2, defined as inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, model-based valuation techniques for which all significant assumptions are observable in the market or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and Level 3, defined as unobservable inputs that are not corroborated by market data.

The fair values of cash, accounts receivable, trade accounts payable, capital expenditures payable, and certain other current assets and accrued expenses approximate carrying values because of their short-term nature. The carrying value of certain other non-current assets and liabilities approximates fair value. Our assets and liabilities recorded at fair value on a recurring basis include restricted cash money market funds and short-term investments, including investments classified as cash equivalents. We also review goodwill for impairment annually during the fourth quarter of each year. Cash equivalent money market funds and restricted cash money market funds are invested in U.S. money market funds and various U.S. and foreign bank operating and time deposit accounts, which are due on demand or carry a maturity date of less than three months when purchased. No restrictions have been imposed on us regarding withdrawal of balances with respect to our cash equivalents as a result of liquidity or other credit market issues affecting the money market funds we invest in or the

counterparty financial institutions holding our deposits. Short-term investments, including money market funds (Note 7), are valued as follows:


•	Level 1: using quoted market prices in active markets for identical assets.


•	Level 2: using quoted market prices for similar instruments or non-binding market prices that are corroborated by observable market data. We use inputs such as actual trade data, benchmark yields, broker/dealer quotes, and other similar data, which are obtained from quoted market prices, and independent pricing vendors to determine the fair value of these assets and liabilities.

Our derivative financial instruments are valued using quoted market prices for similar assets. Counterparties to these derivative contracts are highly rated financial institutions.

We also measure certain assets and liabilities, including property, plant and equipment and goodwill, at fair value on a nonrecurring basis.

We measure the fair value of our debt for disclosure purposes. The following table presents the fair value of financial instruments that are not recorded at fair value on a recurring basis:



	March 31, 2020				December 31, 2019
	Fair Value		Carrying Value		Fair Value		Carrying Value
	(In thousands)
Senior notes (Level 1)	$	488,701	$	519,355	$	576,875	$	519,211
Revolving credit facilities and term loans (Level 2)	980,901		993,667		940,756		931,023
Total debt	$	1,469,602	$	1,513,022	$	1,517,631	$	1,450,234

The estimated fair value of our senior notes is based primarily on quoted market prices reported on or near the respective balance sheet dates. The estimated fair value of our revolving credit facilities and term loans is calculated using a discounted cash flow analysis, which utilizes market-based assumptions including forward interest rates adjusted for credit risk.

14. Commitments and Contingencies

We generally warrant that our services will be performed in a professional and workmanlike manner and in compliance with our customers’ specifications. We accrue costs for known warranty issues. Historically, our warranty costs have been immaterial.

Legal Proceedings

We are involved in claims and legal proceedings and may become involved in other legal matters arising in the ordinary course of our business. We evaluate these claims and legal matters on a case-by-case basis to make a determination as to the impact, if any, on our business, liquidity, results of operations, financial condition or cash flows. Although the outcome of these matters is uncertain, we believe that the ultimate outcome of these claims and proceedings, individually and in the aggregate, will not have a material adverse impact to us. Our evaluation of the potential impact of these claims and legal proceedings on our business, liquidity, results of operations, financial condition or cash flows could change in the future.

In accordance with the accounting guidance for loss contingencies, including legal proceedings, lawsuits, pending claims and other legal matters, we accrue for a loss contingency when we conclude that the likelihood of a loss is probable and the amount of the loss can be reasonably estimated. We adjust our accruals from time to time as we receive additional information, but the loss we incur may be significantly greater than or less than the amount we have accrued. We disclose loss contingencies if we believe they are material and there is at least a reasonable possibility that a loss has been incurred. Attorney fees related to legal matters are expensed as incurred.
