TEMPE, Ariz. — (BUSINESS WIRE) — July 30, 2018 — Amkor Technology, Inc. (NASDAQ: AMKR), a leading provider of semiconductor packaging and test services, today announced financial results for the second quarter ended June 30, 2018.

"Second quarter results exceeded expectations, with sequential growth in net sales, operating margin and earnings per share," said Steve Kelley, Amkor's CEO. "Demand was higher across all of our end markets. Communications was especially strong."

		($ in millions, except per share data)
Net sales		$1,066		$1,025		$1,008
Gross margin		15.9%		15.4%		17.5%
Net income attributable to Amkor1		$33		$10		$119
Earnings per diluted share1		$0.14		$0.04		$0.50
EBITDA1,2		$208		$175		$321
1) Q2 2017 net income included the sale of our K1 factory in Korea. The sale price was $142 million, and we recognized an after-tax gain of $82 million ($0.34 per diluted share).
2) EBITDA is a non-GAAP measure. The reconciliation to the comparable GAAP measure is included below under "Selected Operating Data."

"Net sales growth drove sequentially higher profits and EBITDA," said Megan Faust, Amkor’s CFO. "In addition, we are in the process of refinancing the remaining $200 million 6.625% Senior Notes due 2021 with proceeds from a recently completed foreign bank loan. This refinancing is expected to generate net annualized interest savings of approximately $11 million."

Business Outlook

"We expect third quarter 2018 net sales to be about $1.14 billion, up 7% sequentially, primarily due to seasonal strength in the communications market," said Kelley.

Third quarter 2018 outlook (unless otherwise noted):

• Net sales of $1.10 billion to $1.18 billion
• Gross margin of 15% to 17%
• Net income of $28 million to $55 million, or $0.12 to $0.23 per diluted share
• Full year capital expenditures of approximately $600 million

In the press release above we provide EBITDA, which is 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 to be relevant and useful information to our investors because it provides additional information in assessing our financial operating results. Our management uses EBITDA in evaluating our operating performance, our ability to service debt and our ability to fund capital expenditures. However, EBITDA has certain limitations in that it does 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 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 may not be comparable to similarly titled measures reported by other companies. Below is our reconciliation of EBITDA to U.S. GAAP net income.
