Gross profit was $60.4 million or 32.3%, as a percent of revenue, for the fourth quarter of 2010. This compares to gross profit of $69.3 million or 33.1% for the third quarter of 2010 and $37.1 million or 22.9% for the combined three-month period ended December 31, 2009. For the full year 2010, gross profit was $243.6 million or 31.6% compared to $158.5 million or 28.3% for combined 2009.

“2010 proved to be a strong year for MagnaChip. We are very pleased that our refocused business strategy, strong pipeline of new products and enhanced manufacturing capacity has positioned us well for solid growth,” said Sang Park, MagnaChip Semiconductor’s Chairman and Chief Executive Officer. “Based on our solid design win momentum and booking activity we are excited about the outlook for 2011 and beyond for our Semiconductor Manufacturing Services, Display and Power Solutions products.”

Operating expense was $36.9 million or 19.7% of revenue for the fourth quarter of 2010. This compares to $39.8 million or 19.0% of revenue for the third quarter of 2010 and $40.0 million or 24.6% of revenue for the combined three-month period ended December 31, 2009. For the full year 2010, operating expense was $152.2 million or 19.8% compared to $142.2 million or 25.4% for combined 2009.

Operating income was $23.5 million for the fourth quarter of 2010 or 12.6% of revenue. This compares to operating income of $29.6 million or 14.1% of revenue for the third quarter of 2010 and operating loss of $2.8 million for the combined three-month period ended December 31, 2009. For the full year 2010, operating income was $91.4 million or 11.9% compared to $16.4 million or 2.9% for combined 2009.

Net income, on a GAAP basis, for the fourth quarter of 2010 totaled $12.3 million. This compares to net income of $61.5 million for the third quarter of 2010 and net income of $818.8 million for the combined three-month period ended December 31, 2009. For the full year 2010, net income was $74.1 million compared to $839.1 million for combined 2009. Net income, for the fourth quarter of 2010, was impacted primarily by a relatively constant foreign currency translation in the fourth quarter compared to a foreign currency gain of $41.4 million for the third quarter of 2010 and a foreign currency gain of $16.7 million and net reorganization gain of $809.0 million for the combined three-month period ended December 31, 2009, respectively. The net foreign currency exposure is primarily related to non-cash translation gains or losses for intercompany balances that are denominated in U.S. dollars. The net reorganization gain of $809.0 million in the one-month period ended October 25, 2009 represents the impact of non-cash reorganization income and expense items directly associated with our reorganization proceedings and primarily reflects the discharge of liabilities of $798.0 million.

Adjusted net income, a non-GAAP measurement, for the fourth quarter of 2010 totaled $17.4 million compared to $26.2 million for the third quarter of 2010, and $20.2 million for the combined three-month period ended December 31, 2009. For the full year 2010, adjusted net income was $89.2 million compared to $22.6 million for combined 2009.

Adjusted EBITDA, a non-GAAP measurement, for the fourth quarter of 2010 totaled $39.7 million compared to $45.7 million for the third quarter of 2010, and $32.6 million for the combined three-month period ended December 31, 2009. For the full year 2010, adjusted EBITDA was $157.9 million compared to $98.7 million for combined 2009.

Management believes that non-GAAP financial measures, when viewed in conjunction with GAAP results, can provide a more meaningful understanding of the factors and trends affecting MagnaChip Semiconductor’s business and operations. However, such non-GAAP financial measures have limitations and should not be considered as a substitute for net income or as a better indicator of our operating performance than measures that are presented in accordance with GAAP.

Combined cash balances (cash and cash equivalents plus short-term investments) totaled $172.2 million at the end of the fourth quarter of 2010, an increase of $10.7 million from the end of the prior quarter. Cash provided from operations totaled approximately $24.8 million for the fourth quarter of 2010. This compares to $30.7 million for the third quarter of 2010 and $11.3 million for the combined three-month period ended December 31, 2009.
