CHANDLER, Ariz.—(BUSINESS WIRE)—May 1, 2007— Amkor Technology, Inc. (NASDAQ: AMKR) reported first quarter 2007 sales of $651 million, up 1% from the first quarter of 2006 and down 5% sequentially from the fourth quarter of 2006. Amkor's first quarter 2007 net income was $35 million, or $0.18 per diluted share, compared with net income of $34 million, or $0.19 per diluted share, in the first quarter of 2006.

"Our first quarter performance reflected a seasonal slowdown in demand together with an inventory correction at the customer level," said James Kim, Amkor's Chairman and Chief Executive Officer. "We remain committed to maintaining our technology and product leadership in key growth markets and to exercising capital and pricing discipline so that we can achieve consistent profitability and free cash flow. We are investing capital in strategic growth areas of flip chip, wafer level processing, 3D and other advanced packaging, and we continue to prudently expand our capabilities in test development, wafer probe and final test."

"While our first quarter volumes were seasonally lower in most product categories, we saw continued growth in flip chip and modules," said Kim. "Our flip chip solutions encompass turnkey wafer bump, wafer probe, assembly and final test, and Amkor is well positioned to support a broad range of high-performance applications, including gaming, networking, wireless and advanced servers. Our module solutions currently support customers in the wireless market."

"Commencing with the second quarter of 2005 and through the third quarter of 2006, we enjoyed six consecutive quarters of above-average growth in our business. Within this context, and mindful of the fact that our business is increasingly influenced by growth in the world economy and levels of consumer spending, we expect the softness we experienced in the first quarter will be followed by modest growth for the rest of 2007," said Kim.

"Our first quarter financial performance was in line with guidance and is further evidence of our success in achieving consistent levels of profitability and generating free cash flow," said Ken Joyce, Amkor's Chief Financial Officer.

"First quarter 2007 net sales increased $6 million or 1% over the first quarter of 2006. A nearly 10% decline in unit shipments in 2007 was more than offset by a stable pricing environment and mix shift to packages with higher average selling prices," said Joyce. "Compared with the fourth quarter of 2006, sales were down 5% on lower unit volumes across most of our product lines, with notable exceptions for flip chip and modules. The lower unit volumes in the first quarter were due to anticipated seasonal declines and to a lesser extent customer inventory corrections during the quarter."

Gross margin in the first quarter of 2007 was 22.6% down from 24.0% in the first quarter of 2006 and 25.3% in the fourth quarter of 2006. On a year-over-year basis, factory wage increases and increased factory overhead costs more than offset the benefit of factory workforce reductions. Compared with the fourth quarter of 2006, the decline in gross margin principally reflected the impact of our operating leverage on lower sales volume, coupled with growth in packages with a higher material content.

Selling, general & administrative expenses in the first quarter of 2007 were $2.5 million higher than the first quarter of 2006, reflecting higher spending for professional fees, indirect factory costs, and incentive compensation partially offset by a $3 million gain recognized on disposition of real property used for administrative purposes. Compared with the fourth quarter of 2006, and including the above $3 million gain, first quarter of 2007 SG&A expenses were essentially flat. Our current expectation is that SG&A costs in the second quarter of 2007 will be up slightly from the first quarter reflecting increased indirect factory administrative expenses and litigation activity.

"Capital additions totaled $55 million in the first quarter of 2007. Our continued focus on improving overall asset productivity allowed us to moderate our capital additions," said Joyce. "Our capacity expansion continues to focus on strategic growth areas, including wafer bump, wafer level packaging and flip chip. We are currently targeting second quarter 2007 capital additions of $70 million and full year capital additions in the range of $250 - $300 million. We are prepared to adjust these figures depending on business conditions."

"We have achieved positive free cash flow for the past six quarters, and given our current view of business conditions, we anticipate this trend will continue throughout 2007," said Joyce. "We continue to address our capital structure and reduce ongoing interest expense. In March we used available cash to retire the remaining $142 million of 5% convertible debt at maturity. In April we refinanced a $300 million term loan due 2010 (accruing interest at LIBOR + 450 bp) with a seven-year amortizing loan due 2014 (accruing interest at approximately LIBOR + 125 bp). Taken together, these actions will result in approximately $13 million of interest savings for the remainder of 2007." In connection with the April 2007 refinancing, Amkor will record a charge in the second quarter, with no tax effect, of $16 million, reflecting $9 million in prepayment fees and $7 million to write off unamortized deferred debt issuance costs.

The income tax rate was 10.5% for the first quarter of 2007 and we anticipate an effective tax rate of 6.7% for the year. This reflects the utilization of foreign net operating loss carryforwards and tax holidays in certain of our foreign jurisdictions. At March 31, 2007, Amkor had U.S. net operating losses available for carryforward totaling $400 million expiring through 2027 and $60 million of non-U.S. operating losses available for carryforward, expiring through 2012.

Selected operating data for the first quarter 2007 is included in a section before the financial tables.

On the basis of our customers' forecasts, we have the following expectations for the second quarter of 2007:

-- Sales up 3% to 4% from the first quarter of 2007

-- Gross margin of around 23%

-- Net income in the range of $0.13 to $0.16 per diluted share, which includes charges of $0.08 per share associated with the April 2007 refinancing
