SEOUL, South Korea and CUPERTINO, Calif., July 27, 2011 /PRNewswire via COMTEX/ — MagnaChip Semiconductor Corporation (NYSE: MX), a Korea-based designer and manufacturer of analog and mixed-signal semiconductor products, today announced financial results for the second quarter ended June 30, 2011.

Revenue for the second quarter of 2011 was $203.7 million, an 8.4% increase compared to $187.9 million for the first quarter of 2011, and a 4.6% increase compared to $194.7 million for the second quarter of 2010.

Gross profit was $66.2 million or 32.5%, as a percent of revenue, for the second quarter of 2011. This compares to gross profit of $56.5 million or 30.1% for the first quarter of 2011 and $64.5 million or 33.1% for the second quarter of 2010.

“I am very pleased that revenue for our three business segments grew during the quarter and that gross profit expanded as a result of strong execution by our sales and manufacturing organizations,” said Sang Park, MagnaChip’s Chairman and Chief Executive Officer. “Not only did our Power Solutions segment grow 16 percent sequentially, but our Display Solutions segment posted double-digit revenue growth this quarter as well. Additionally, our Foundry business was up 5% over the March quarter despite overall market softness as reported by several foundry providers. I am very encouraged by the traction of our new products, which has increased the design-win activity for both our Power Segment and Foundry Services. This better positions us strategically for growth in the coming years.”

Net income, on a GAAP basis, for the second quarter of 2011 totaled $31.6 million or $0.78 per diluted share. This compares to net income of $22.5 million or $0.57 per diluted share for the first quarter of 2011 and a net loss of $30.7 million or $0.81 per diluted share for the second quarter of 2010.

Adjusted net income, a non-GAAP measurement, for the second quarter of 2011 totaled $22.5 million or $0.56 per diluted share compared to $15.7 million or $0.40 per diluted share for the first quarter of 2011 and $25.7 million or $0.68 per diluted share for the second quarter of 2010.

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 Corporation’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 $177.8 million at the end of the second quarter of 2011, a decrease of $16.4 million from the end of the prior quarter due to a cash payment of $38.2 million related to the $35 million repurchase of senior notes during the quarter. Cash provided from operations totaled approximately $48.3 million for the second quarter of 2011.

SEOUL, South Korea, April 4, 2011 — MagnaChip Semiconductor Corporation (“MagnaChip Semiconductor”) (NYSE: MX) a Korea-based designer and manufacturer of analog and mixed-signal semiconductor products, today announced that it now offers cost competitive and state of the art copper wire bonding technology for the specialized needs of foundry customers.

Copper bonding employs copper wires instead of gold for interconnection and has become one of the most preferred methods to reduce overall package cost for semiconductor applications as the price of gold continues to rise.

Copper wire offers significant advantages over gold wire. First, copper is three to five times less costly than gold. Substituting gold with copper can achieve a packaging cost savings of about 20% to 30%. Copper wire is about 30% more conductive than gold, making it a superior electrical conductor. Copper also has about 25% higher thermal conductivity. In addition, because of copper’s lower tendency to form intermetallic compounds, copper bonds can offer higher reliability at elevated temperatures than gold bonds.

One of the major challenges of copper wire bonding has been the significant mechanical stress imposed on bonding pads, which often resulted in damage to silicon wafers in the form of cracks beneath the pads. To resolve this issue, MagnaChip worked with the major packaging companies, including Amkor, to develop and qualify an enhanced silicon bonding process.

TJ Lee, Senior Vice President and General Manager, Corporate Engineering, commented, “We are very pleased to announce the offering of our cost competitive copper wire bonding solutions to meet the increasing demand for a gold wire alternative. Foundry customers can now migrate to MagnaChip’s copper wire bonding technology and recognize a direct 20% to 30% cost savings. It is our goal to provide innovative and cost-effective manufacturing solutions for our customers.”

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.
