MagnaChip Reports First Quarter 2011 Financial Results

· Revenue of $188 Million up Sequentially and Year-over-Year
· Power Solutions Revenue Grew 126% over Q1 2010
· Net Income $22 Million or $0.57 per diluted share

SEOUL, South Korea and CUPERTINO, Calif., April 27, 2011 — MagnaChip Semiconductor Corporation (NYSE: MX) today announced financial results for the first quarter ended March 31, 2011.Revenue for the first quarter of 2011 was $187.9 million, a 4.7% increase compared to $179.5 million for the first quarter of 2010, and a 0.6% increase compared to $186.8 million for the fourth quarter of 2010.Gross profit was $56.5 million or 30.1%, as a percent of revenue, for the first quarter of 2011. This compares to gross profit of $49.4 million or 27.5% for the first quarter of 2010 and $60.4 million or 32.3% for the fourth quarter of 2010.“I am very pleased with our performance in what is typically a seasonally down quarter for MagnaChip and the industry,” said Sang Park, MagnaChip’s Chairman and Chief Executive Officer. “Our Power Solutions business segment grew 11 percent sequentially and more than doubled over the same period last year. Our foundry business was down less than expected for this seasonally weaker quarter and our Display Solutions segment was up for the quarter. All indications point to 2011 being another solid year for growth in revenue and margin expansion for MagnaChip.”Net income, on a GAAP basis, for the first quarter of 2011 totaled $22.5 million or $0.57 per diluted share. This compares to net income of $31.1 million or $0.81 per diluted share for the first quarter of 2010 and net income of $12.3 million or $0.31 per diluted share for the fourth quarter of 2010.

Adjusted net income, a non-GAAP measurement, for the first quarter of 2011 totaled $15.7 million or $0.40 per diluted share compared to $19.9 million or $0.52 per diluted share for the first quarter of 2010 and $17.4 million or $0.44 per diluted share for the fourth 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 $194.2 million at the end of the first quarter of 2011, an increase of $22.0 million from the end of the prior quarter. Cash provided from operations totaled approximately $19.2 million for the first 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.”
