MagnaChip Reports Second Quarter 2018 Financial Results

— Revenue of Nearly $200 Million Fueled by Record Demand for OLED Display Drivers —

SEOUL, South Korea and SAN JOSE, Calif., July 30, 2018 — MagnaChip Semiconductor Corporation (NYSE: MX) today announced financial results for the second quarter of 2018 ended June 30.

Q2 2018 Summary

 

    Revenue of $199.7 million exceeded high-end of guidance range of $182-188 million; revenue increased 19.8% Year-over-Year (YoY)

 

    Record OLED display driver revenue of $62.2 million quadrupled YoY and increased 81.3% from Q1 2018

 

    Power products revenue increased 13.3% YoY; Foundry revenue decreased 0.8% YoY on a reported basis, but had better product mix with 17% increase in new products YoY

 

    Gross profit margin of 27.0% in line with 26-28% guidance range; gross profit margin declined by one percentage point YoY and gross profit dollars increased 15.4% YoY

 

    Operating income of $13.9 million increased 42.8% YoY

 

    Adjusted EBITDA of $23.5 million increased 15.7% YoY

 

    Cash flow from operations of $25.7 million up fivefold YoY; free cash flow, which represents cash flow from operations less capital expenditures, totaled $17.3 million as compared with a negative $0.2 million a year ago

CEO Comments from YJ Kim: “Revenue in the second quarter far exceeded previous guidance due to record demand for our OLED display drivers coupled with a higher-than-expected number of launches of OLED smartphones, primarily in China. Our OLED revenue in Q2 quadrupled from the second quarter a year ago and increased 81.3% sequentially. Given our current business visibility, OLED revenue in 2018 is expected to exceed the previous record of $161.0 million set in 2016. Revenue in the Power standard products business increased by double digits year-over-year, while new product revenue in our Foundry business increased by 17% year over year. Both Foundry and Power businesses recorded a sequential increase in revenue in Q2 as compared to Q1 2018.”

CFO Comments from Jonathan Kim:

“Key financial metrics showed continued improvement in the second quarter, driven primarily by higher-than-expected revenue. Revenue, gross profit dollars, operating income and Adjusted EBITDA, all showed double-digit percentage gains year-over-year, as well as sequentially. Operating income, Adjusted EBITDA and gross profit increased 88.6%, 51.7%, and 20.8% sequentially, and the Company remains committed to show improvement in gross profit over time. Our improved financial performance helped MagnaChip achieve positive free cash flow of $17.3 million in the second quarter as compared to negative free cash flow in the same year-ago period. We anticipate that we will continue to generate positive free cash flow for the second half of 2018.”

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:

EBITDA for the periods indicated is defined as net income (loss) before interest expense, net, income tax expenses and depreciation and amortization. We prepare Adjusted Net Income by adjusting net income (loss) to eliminate the impact of a number of non-cash expenses and other items that may be either one time or recurring that we do not consider to be indicative of our core ongoing operating performance. We believe that Adjusted Net Income is particularly useful because it reflects the impact of our asset base and capital structure on our operating performance. We define Adjusted Net Income for the periods as net income (loss), adjusted to exclude (i) early termination charges, (ii) equity-based compensation expense, (iii) foreign currency loss (gain), net, (iv) derivative valuation loss, net and (v) restatement related expenses (gain), net.
