HSINCHU, Taiwan, Aug. 9, 2018 /PRNewswire-FirstCall/ -- ChipMOS TECHNOLOGIES INC. ("ChipMOS" or the "Company") (Taiwan Stock Exchange: 8150 and NASDAQ: IMOS), an industry leading provider of outsourced semiconductor assembly and test services ("OSAT"), today reported unaudited consolidated financial results for the second quarter ended June 30, 2018. All U.S. dollar figures cited in this press release are based on the exchange rate of NT$30.43 against US$1.00 as of June 29, 2018.

All the figures were prepared in accordance with Taiwan-International Financial Reporting Standards ("Taiwan-IFRS").

Net revenue for the second quarter of 2018 was NT$4,491.6 million or US$147.6 million, an increase of 12.0% from NT$4,010.9 million or US$131.8 million in the first quarter of 2018 and a decrease of 1.1% from NT$4,541.2 million or US$149.2 million for the same period in 2017.

Net profit attributable to equity holders of the Company for the second quarter of 2018 was NT$124.1 million or US$4.1 million, and NT$0.15 or US$0.005 per basic common share and NT$0.14 or US$0.005 per diluted common share, as compared to net profit attributable to equity holders of the Company for the first quarter of 2018 of NT$22.8 million or US$0.7 million, and NT$0.03 or US$0.001 per basic common share and NT$0.03 or US$0.001 per diluted common share, and compared to net profit attributable to equity holders of the Company in the second quarter of 2017 of NT$321.4 million or US$10.6 million, and NT$0.38 or US$0.01 per basic common share and NT$0.38 or US$0.01 per diluted common share. Net earnings for the second quarter of 2018 were US$0.10 per diluted ADS, compared to US$0.02 per diluted ADS for the first quarter of 2018 and US$0.25 per diluted ADS in the second quarter of 2017. Net profit in the second quarter of 2018 reflects the adverse impact of higher depreciation and withholding expenses.

S.J. Cheng, Chairman and President of ChipMOS, said, "This was a strong quarter for us as we delivered on our financial goals and efforts to increase shareholder value. We achieved 12% revenue growth in Q2 compared to Q1 and improved our gross margin to 16.4% from 14.6% in the prior quarter. Based on capacity constraints and market demand we raised our DDIC prices in May. DDIC demand growth is expected to continue through the second half of 2018 led by gold bumping and mixed-signal testing and assembly services related to new, narrow bezel, full screen smartphone models, among other areas. We continue to manage our capacity levels closely in support of growth areas, including 12" fine pitch chip-on-film and TDDI, where revenue grew in the double digits compared to Q1 to represent in the high single digit of our total Q2 revenue. TDDI test programs require up to 3 times the test time of regular DDIC test programs, putting our capacity at an even higher premium as customers seek to secure the needed support for their expected growth. We are also encouraged by growth in our flash assembly and test business, which is benefiting from diverse demand drivers, including IoT, smart speakers and gaming products. As a result, our flash business revenue grew more than 15% in Q2 compared to Q1, and represented nearly 23% of total Q2 revenue. Overall, we think the rest of the year can be quite positive as we benefit from our growth strategy and improved capital structure."

Silvia Su, Vice President of Finance and Accounting, commented, "We held our operating expenses in check as we carefully manage our resources and operating structure in support of the higher demand levels we are seeing. Our focus on expense controls, along with increased demand and our DDIC price increase in May, helped us improve gross margin to 16.4% in Q2. We expect to see further improvement in gross margin as we move through 2018 based on current market conditions. We ended the second quarter with a balance of cash and cash equivalents of US$134.2 million, and a net debt balance of US$141.4 million with a net debt to equity ratio of 23.3%. This is after CapEx of $32.1 million in the second quarter, the majority of which was invested in expanding our LCD driver capacity to meet customer demand levels, mainly for DDIC test and 12" fine pitch chip-on-film. Our balance sheet is allowing us to reward shareholders through the issuance of cash dividend and a capital return related to our 2018 Capital Reduction plan. The dividend and the 2018 Capital Reduction plan have been approved by shareholders and Taiwan's Competent Authority, with distributions expected in the fourth quarter of 2018."
