SEOUL, South Korea and CUPERTINO, Calif., Oct. 31, 2011 — MagnaChip Semiconductor Corporation (“MagnaChip Semiconductor”) (NYSE: MX), an Asia-based designer and manufacturer of analog and mixed-signal semiconductor products, has launched a 4-channel LED driver for notebook computer applications and a 6-channel LED driver for tablet PCs.

The 4-channel LED driver, MAP3105, has an input voltage range of 4V to 26V and an embedded MOSFET which can boost output voltage to as much as 45V with a switching range of 500KHz ~2MHz. MAP3105 also maximizes LED brightness by increasing input current up to 40mA per channel, while minimizing current matching to less than 2% per channel. MAP3105 is offered in a TQFN-16L package and is 3mm x 3mm in size.

In addition, the 6-channel LED driver, MAP3106, has an input voltage range of 5V to 24V and an embedded MOSFET which can boost output voltage to as much as 40V with a switching range of 330KHz ~1MHz. MAP3106 is offered in a QFN package and is 4mm x 4mm in size.

Operating efficiency and safety have also been enhanced through a multitude of designed-in protection functions including current overload protection, LED open/short protection, over voltage protection, open Schottky diode protection among others. Detailed performance options and specifications can readily be found on the company’s website at www.magnachip.com.

H.K. Kim, Executive Vice President of MagnaChip’s Power Solutions Division said, “We are very pleased to have launched the fully integrated 4-channel and 6-channel LED backlight driver which expands our product portfolio of drivers for notebook and tablet PCs. Our goal is to continue to deliver leading-edge products by expanding our product portfolio with the latest in advanced technologies.”

MagnaChip Reports Third Quarter 2011 Financial Results

– Power Solutions Revenue Grew 11% Sequentially and 48% Year-over-Year
– Display Solutions Revenue Grew 11% Sequentially and 18% Year-over -Year

SEOUL, South Korea and CUPERTINO, Calif., Oct. 26, 2011 — MagnaChip Semiconductor Corporation (NYSE: MX), a Korea-based designer and manufacturer of analog and mixed-signal semiconductor products, today announced financial results for the third quarter ended September 30, 2011.

Revenue for the third quarter of 2011 was $200.4 million, a 1.6% decrease compared to $203.7 million for the second quarter of 2011, and a 4.3% decrease compared to $209.4 million for the third quarter of 2010.

Gross profit was $60.1 million or 30.0%, as a percent of revenue, for the third quarter of 2011. This compares to gross profit of 66.2 million or 32.5 % for the second quarter of 2011 and $69.3 million or 33.1% for the third quarter of 2010.

“Despite continued weakness in the global semiconductor market, we managed to deliver results consistent with our original guidance while growing Power Solutions 11% sequentially and 48% year-over-year,” said Sang Park, MagnaChip’s Chairman and Chief Executive Officer. “While many of our peers reduced their outlook as the quarter progressed, we delivered on our initial expectations based on the strength of our blue-chip customer relationships, diverse product portfolio and growing Power and Display Solutions businesses. Having a strategy that capitalizes on the strength of our Foundry, Display and Power products better positions us for growth as the macro environment begins its recovery.”

Net loss, on a GAAP basis, for the third quarter of 2011 totaled $56.0 million or $1.43 per diluted share. This compares to net income of $31.6 million or $0.78 per diluted share for the second quarter of 2011 and a net income of $61.5 million or $1.57 per diluted share for the third quarter of 2010. Net loss was primarily impacted by a non-cash foreign currency translation loss of $68.1 million due to the appreciation of the US dollar against the Korean won associated with intercompany balances.

Adjusted net income, a non-GAAP measurement, for the third quarter of 2011 totaled $18.2 million or $0.46 per diluted share compared to $22.5 million or $0.56 per diluted share for the second quarter of 2011 and $26.2 million or $0.67 per diluted share for the third 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 restricted cash) totaled $168.7 million at the end of the third quarter of 2011, a decrease of $9.1 million from the end of the prior quarter primarily due to a cash payment of $12.1 million related to the $11.3 million repurchase of senior notes during the quarter. Cash provided from operations totaled approximately $18.7 million for the third quarter of 2011.

SEOUL, South Korea and CUPERTINO, Calif., Oct. 3, 2011 — MagnaChip Semiconductor Corporation (“MagnaChip Semiconductor”) (NYSE: MX), a Korea-based designer and manufacturer of analog and mixed-signal semiconductor products, has launched a series of 650V High Voltage (HV) MOSFET products for use in LCD-TV and LCD monitor applications.

The 650V MOSFET is used as a power conversion part for Switched-Mode Power Supplies where flyback topology is adopted. The main applications are typically LCD-TVs and LCD monitors which require high-speed switching. In mission critical situations, the use of power supplies which incorporate the 650V HV MOSFET is essential to securing a stable and regulated supply of power, particularly in countries which experience frequent power supply disruptions.

With the launch of our new series of 650V MOSFETs, MagnaChip Semiconductor will be able to meet the growing customer demand for high voltage MOSFETs used in power supplies and other devices. This also broadens our portfolio of MOSFET products which will now range from 20V up to 650V devices.

HK Kim, Executive Vice President of MagnaChip’s Power Solutions Division said, “We will continue to expand our MOSFET market share and grow our Power Solutions business by accelerating the introduction of new and value added MOSFETs to meet the growing demand of our current and future customer base.”
