Second Quarter Financial Review
Total Revenue

Total revenue in the second quarter of 2018 was $199.7 million, up 19.8% as compared to reported revenue of $166.7 million from the second quarter of 2017, and up 20.4% from $165.8 million in the first quarter of 2018.

Segment Revenue and Segment Adjustments
In January 2018, as part of the Company’s ongoing portfolio optimization effort to realign business processes and streamline the organizational structure, the Company transferred a portion of the non-OLED Display business, which was $4.4 million for Q1 2018 and $3.7 million for Q2 2018, from the Standard Products Group to the Foundry Services Group. As a result, the historical financial results below are discussed both on an as reported and as adjusted basis for comparative purposes.

Foundry Services Group revenue in the second quarter was $80.9 million, down 0.8% from reported revenue of $81.5 million from the second quarter of 2017, and up 4.5% from the first quarter of 2018 on an as reported basis; and down 7.6% from the second quarter of 2017, and down 3.2% from the first quarter of 2017 on an as adjusted basis.

Following the strategic realignment and portfolio optimization discussed above, Standard Products Group revenue in the second quarter of 2018 was $118.7 million, up 39.6% year-over-year on a reported basis and up 34.4% sequentially; and up 50.2% year-over-year on an as adjusted basis. The improved results in the Standard Products Group reflected a sharp improvement in mobile OLED driver revenue in connection with the introduction of new OLED smartphones from China manufacturers, and higher demand for premium Power products.

Total Gross Profit and Gross Profit Margin
Total gross profit in the second quarter of 2018 was $53.9 million or 27.0% as a percentage of sales as compared with gross profit of $46.7 million or 28.0% gross profit margin in the second quarter of 2017, and $44.6 million or 26.9% gross profit margin for the first quarter of 2018.

Segment Gross Profit Margin
Foundry Services Group gross profit margin was 27.4% in the second quarter of 2018 as compared with, on an as reported basis, 28.7% in the second quarter of 2017 and 26.7% in the first quarter of 2018. The Foundry Services Group gross profit margin was, on an as adjusted basis, 28.2% in the second quarter of 2017 and 27.9% in the first quarter of 2017. The Standard Products Group gross profit margin was 26.6% in the second quarter of 2018 as compared with, on an as reported basis, 27.2% in the second quarter of 2017, and 27.2% in the first quarter of 2018. The Standard Products Group gross profit margin was, on an adjusted basis, 27.7% in the second quarter of 2017, and 23.3% in the first quarter of 2017.

Operating Income, Net Income, Adjusted Net Income, Adjusted EBITDA
Operating income, on a GAAP basis, for the second quarter was $13.9 million as compared with $9.7 million in the second quarter of 2017 and $7.4 million in the first quarter of 2018.

Net loss on a GAAP basis, for the second quarter was $21.5 million or $0.62 per basic and diluted share as compared with a net loss of $8.1 million or $0.24 per basic and diluted share in the second quarter of 2017, and net income of $2.8 million or $0.08 per basic and diluted share in the first quarter of 2018. The net loss in the second quarter of 2018 was attributable primarily to a non-cash foreign exchange loss on the Company’s intercompany loans.

Adjusted Net Income, a non-GAAP financial measure, for the second quarter of 2018 totaled $8.9 million or $0.26 per basic share and $0.23 per diluted share, as compared with Adjusted Net Income of $7.8 million or $0.23 per basic share and $0.21 per diluted share in the second quarter of 2017, and compared with Adjusted Net Income of $1.4 million or $0.04 per basic and diluted share in the first quarter of 2018.

Adjusted EBITDA, a non-GAAP financial measure, in the second quarter was $23.5 million or 11.8% of revenue, as compared with Adjusted EBITDA of $20.3 million or 12.2% of revenue in the second quarter of 2017, and compared with Adjusted EBITDA of $15.5 million or 9.3% of revenue in the first quarter of 2018.

Management believes that non-GAAP financial measures, when viewed in conjunction with GAAP results, can provide a meaningful understanding of the factors and trends affecting MagnaChip’s business and operations and assist in evaluating our core operating performance. 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. A reconciliation of GAAP results to non-GAAP results is included in this press release.

Cash and cash equivalents totaled $131.7 million at the end of the second quarter, up from $123.1 million at the end of the first quarter of 2018.

Note: The following table sets forth information relating to our operating segments (in thousands). The historical amounts below are presented both on an as reported and as adjusted basis to show the impact of the strategic realignment and transfer of a portion of the non-OLED Display business from the Standard Products Group to the Foundry Services Group beginning in the first quarter of 2018:

SEOUL, South Korea and SAN JOSE, Calif., July 16, 2018 /PRNewswire/ — MagnaChip Semiconductor Corporation (“MagnaChip”) (NYSE: MX), a designer and manufacturer of analog and mixed-signal semiconductor products, announced today that it now offers planar-type Hall-effect sensors for foundry customers.

The Hall-effect sensor has been adopted by the market for an increasing number of applications, such as smartphone cameras for the closed-loop auto focus feature and for the auto iris function, etc. Since 2014, MagnaChip has been mass-producing Hall switches and electrical compasses using the planar-type Hall-effect sensor. The Hall-effect sensor was suitable for high sensitivity and low-corner frequency, and features 50x50um2 in size. The initial products were characterized by Hall resistance of 2.4K ohms, sensitivity of 44.5mV/VT and a corner frequency of 500Hz. Most of all, it was recognized for its robustness and stability against noise. With outstanding features, the initial products were well adopted in the market and this in turn prompted MagnaChip to provide the planar-type Hall-effect sensors to its existing and potential foundry customers.

The key benefit of MagnaChip’s Hall-effect sensor is that it can be easily integrated into a customer’s design by adding only one mask to various processes that the foundry already offers. In addition, the integration of the Hall-effect sensors can be made without making any changes in electrical characteristics and it is offered regardless of the technology node, ranging from 0.13um to 0.35um. The process design kit (PDK) provides P-cell and Verilog-A model, with availability to a temperature of up to 150ºC to ensure a wider use in diverse applications, such as the fast growing IoT and automotive markets.

Furthermore, MagnaChip is developing a vertical Hall-effect sensor with the direction of the magnetic field being parallel to the silicon surface, which enables 3 dimensional Hall sensing capabilities. A vertical Hall-effect sensor can also be used in a wide range of applications, including proximity switching, positioning, speed detection and current sensing applications. MagnaChip anticipates that it will develop a variety of Hall-effect sensors to meet the growing needs of its global foundry customers.

“We are delighted to provide foundry services using the Hall-effect sensor,” said YJ Kim, Chief Executive Officer of MagnaChip. “We will continue to make efforts to meet the diverse and specialized expectations of our global foundry customers by offering customized and tailored Analog and Mixed-Signal foundry processes and services.”
