TEMPE, Ariz. — (BUSINESS WIRE) — April 27, 2015 — Amkor Technology, Inc. (NASDAQ: AMKR), a leading provider of semiconductor packaging and test services, today announced financial results for the first quarter ended March 31, 2015.

“First quarter results met our expectations," said Steve Kelley, Amkor's president and chief executive officer. "Sales grew 7% year-on-year driven by strong demand for our advanced packaging and test technologies. We saw a corresponding increase in earnings per share of $0.03 year-on-year."

		($ in millions, except per share amounts)
Net sales		$743		$853		$696			$743		$853		$696

Earnings per diluted share		$0.12		$0.06		$0.09			$0.12		$0.38		$0.09

The gross margin, net income and earnings per diluted share information presented above under Non-GAAP Results excludes charges relating to the settlement of litigation and are non-GAAP measures. The charges are $87 million ($77 million, net of tax) in the fourth quarter 2014. The reconciliation to the comparable GAAP measures is included below under "Selected Operating Data."

Cash and cash equivalents were $494 million, and total debt was $1.5 billion, at March 31, 2015.

Business Outlook

"We anticipate that second quarter 2015 revenues will be flat sequentially, primarily due to inventory adjustments and other issues at a major customer," said Kelley. "We expect demand will strengthen in the second half of 2015 driven by the launch of flagship mobile devices with high Amkor content. Our full year 2015 capital expenditure estimate of around $600 million, including around $150 million of spending for our new K5 facility, remains unchanged."

Based upon currently available information, we have the following expectations for the second quarter 2015:

• Net sales of $725 million to $775 million, down 2% to up 4% from the prior quarter
• Gross margin of 16% to 19%
• Net income of $12 million to $35 million, or $0.05 to $0.15 per diluted share

Selected Operating Data

In the press release above we provide non-GAAP gross margin, non-GAAP net income and non-GAAP earnings per diluted share for the fourth quarter 2014. We present these non-GAAP amounts to demonstrate the impact of the charges we recognized related to the settlement of our litigation with Tessera. Generally, a non-GAAP financial measure is a numerical measure of a company’s performance, financial position or cash flows that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with U.S. generally accepted accounting principles ("U.S. GAAP"). These measures have limitations, including that they exclude the charges for the settlement payments, which are amounts that the company will ultimately have to pay in cash, and should be considered in addition to, and not as a substitute for, or superior to, gross margin, net income and earnings per diluted share prepared in accordance with U.S. GAAP. Below is the reconciliation of non-GAAP gross margin, non-GAAP net income and non-GAAP earnings per diluted share to U.S. GAAP gross margin, net income and earnings per diluted share.

Non-GAAP Financial Measures Reconciliation:
			Q4 2014
