Chandler, Ariz., March 25, 2009 — Amkor Technology, Inc. (NASDAQ: AMKR) today updated certain financial information regarding the first quarter ending March 31, 2009.

Amkor reported that first quarter net sales are tracking to a sequential decline of 30% to 34% from the quarter ended December 31, 2008, which is within the favorable end of the range of the company’s previously announced guidance.  

The company also noted that gross margin for the first quarter is expected to be 8% to 12% of net sales, which is above its previously announced range of 5% to a negative 2%.  Gross margin for the first quarter is expected to benefit from reductions in labor and other costs and foreign government subsidies of employee wages, as well as the strength of the U.S. dollar against certain foreign currencies.  However, gross margin is affected by a number of estimates and other factors which will be reviewed after the end of the quarter and the final gross margin for the first quarter could vary from our current estimate.

Amkor estimates that its current global cash balance has declined to approximately $275 million, reflecting payments relating to a patent license dispute, employee benefit and severance payments and the repurchase of outstanding notes due in 2011.

It is too early for the company to provide other 2009 first quarter financial information and therefore, it is neither updating nor reaffirming its prior guidance regarding net income.
