S.J. Cheng, Chairman and President of ChipMOS, said, “This was a strong year for us as we achieved 10.1% revenue growth for the full year 2019 over 2018 – both a record high revenue level and the highest annual revenue growth since 2015. We also achieved meaningful improvements in profitability, reporting net earnings of NT$3.55 per basic common share or US$2.38 per basic ADS. We continue to drive improvements in our business and financial metrics, while prudently balancing high-return investments to support growth across our base of diversified customers and end markets. Of note, we improved our overall utilization to 76% in Q4 from 74% in Q3, as we benefitted from increased demand for TDDI products given the higher content per unit in newer phones, combined with robust demand trends in our memory business in the second half of the year. We expect these drivers to remain in place as we move through 2020, positioning us to benefit from long-term catalysts driving higher demand from increased AI and automation, larger displays and the ongoing proliferation of smart phone advancements. Importantly, we are executing with close oversight on operating and capital expenses, as we focus on improving revenue growth and higher profitability in the current macroeconomic environment. We are slowing down our CapEx investments and focusing on improvements through automation, while maintaining a strong financial position and balance sheet in order to maintain our leading market position, while navigating the current fluid market situation.”

Silvia Su, Vice President of Finance and Accounting, commented, “We achieved 10.1% revenue growth for the full year 2019 compared to 2018, while decreasing CapEx over the same period. Our focus on leveraging our high margin businesses and high return programs allowed us to expand our gross margin to 22.7% in Q4 up from 21.4% in Q3, and 19.3% for the full year 2019 up from 18.6% in 2018. We meaningfully increased our cash generation with US$200.4 million generated in cash from operations in 2019, and ended the year with a cash and cash equivalents balance of US$157.3 million. During 2019, we distributed our latest cash dividend to investors of NT$1.2 per common share or US$0.764 per ADS, on August 30^th to common stock holders and on September 9^th to ADS holders, as we remain focused on building further value for the Company and its shareholders. In addition, our Board has approved a resolution to distribute NT$1.80 per share pending shareholder approval at our AGM on June 9, 2020. This underscores the Company’s position as a high cash dividend, high yield investment vehicle for investors.”

About Non-Generally Accepted Accounting Principles (“Non-GAAP”) Financial Measures

To supplement the consolidated financial results presented in accordance with the Taiwan-IFRS, ChipMOS uses non-GAAP free cash flow, non-GAAP earnings before interest, taxes, depreciation and amortization (“EBITDA”) and non-GAAP net debt to equity ratio in this press release. The non-GAAP free cash flow represents operating profit plus depreciation, amortization and interest income and less capital expenditures, interest expense, income tax expense and dividend. The non-GAAP EBITDA represents operating profit plus depreciation and amortization. The non-GAAP net debt to equity ratio represents the ratio of net debt, the sum of debt less cash and cash equivalent, divided by equity attributable to equity holders of the Company. These non-GAAP financial measures may not be comparable to similarly titled measures presented by other companies. Other companies may calculate similarly titled measures differently.

The presentation of non-GAAP financial measures is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with the Taiwan-IFRS.

ChipMOS considers the use of non-GAAP free cash flow, non-GAAP EBITDA and non-GAAP net debt to equity ratio provides useful information to management to manage the Company’s business and make financial and operational decisions and also to the investors to understand and evaluate the Company’s business and operating performance.
