<p style="margin-bottom:0pt;margin-top:0pt;margin-right:10.2%;text-indent:0%;font-size:12pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">First quarter consolidated revenue was NT$32.58 billion, down 8.3% QoQ from NT$35.52 billion, in 4Q18 and declined 13.1% YoY from NT$37.50 billion in 1Q18. Consolidated gross margin for 1Q19 was 6.9%. Net income attributable to stockholders of the parent was NT$1.20 billion, with earnings per ordinary share of NT$0.10.</p>
<p style="margin-bottom:0pt;margin-top:0pt;margin-right:10.2%;text-indent:0%;font-size:12pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">Jason Wang, co-president of UMC, said, &#8220;In the first quarter, foundry revenue declined 8.3% QoQ to NT$32.56 billion, leading to a foundry operating loss of 4.6%. Utilization rate was 83%, bringing wafer shipments to 1.61 million 8-inch equivalent wafers. Although overall wafer demand declined during the first quarter, we observed stable wafer shipments from the wireless communications segment, solidified by smartphone related components such as display, RF, application processor and baseband modem. We continue to build on our promise of building shareholder value, and in Q1 our Board of Directors proposed to distribute a cash dividend of approximately NT$0.58 per share, subject to shareholder approval during the annual shareholder meeting (AGM).&#8221;</p>

Going forward, our strategy to stay focused on developing existing logic and specialty solutions across numerous technology platforms will help us enhance our market relevance to secure future business and expand our presence in the IC industry. We are confident that by continuing to responsibly execute our technology development, capacity expansion and customer service, we can bring optimal value to the company, its shareholders, and employees.&#8221;</p>
