Year-over-year revenue increased by 35.3 % to NT$23.72 billion from NT$17.54 billion, and a 10.1% QoQ increase from NT$21.54 billion in 3Q03. The operating income is NT$4.16 billion, a 60.8% increase compared with Q303. The net income for 4Q03 was NT$6.73 billion, increased by 60.1% from NT$4.203 billion in 3Q03. EPS was NT$0.44. Wafer shipments in the forth quarter were 644 thousand 8-inch equivalent wafers (excluding UMCJ and UMCi), a 17.9% increase from 3Q03, and utilization rate was 96%. The blended average selling price (ASP) for the fourth quarter is the same as that in 3Q03. The revenue from 0.13-micron increased nearly 50% and the percentage accounted for the total revenue increased from 9% (Q3) to 12% (Q4). The percentage of revenue from 0.18-micron and below technologies in the fourth quarter was 46%. The total capital expenditure of UMC and subsidiaries (UMCi & UMCJ) was US$740 million in 2003. The expected capital expenditure in 2004 will reach US$2.12 billion, of which US$1.65 billion will be invested for the expansion of 12-inch FABs. "We are pleased to report a sequential increase of over 60% in operating income for the fourth quarter," said Jackson Hu, CEO at UMC. "During this period, we experienced a steady increase in overall demand, particularly from the communications segment, which exhibited a robust rise in orders. Going forward, we expect the first quarter of 2004 to be significantly stronger than the pattern we have seen over the previous several years. Furthermore, we expect over 50% of total net wafer sales to come from 0.18um and below technologies. Compared with 2002, annual revenue for 2003 grew 26%, and net income doubled. This improved financial performance demonstrates our strong competitiveness and points the way toward faster growth." Jackson continued, "During 2003, we continued to invest in state-of-the-art 300mm manufacturing facilities and in the development of silicon IP (intellectual property) to best serve our customers. By the end of 2004, we plan to triple our 300mm manufacturing capacity to 30-thousand 12-inch wafers per month. Planned total capacity, including UMCi, will increase 16% year-over-year, with over half of our total capacity capable of manufacturing chips using 0.18um and below technologies. In the area of customer service, our extensive program to make key IP available to our customers has allowed them to enhance their product performance and speed the time-to-market for their sophisticated system-on-chip (SOC) devices. As we continue the ramp up of 90nm manufacturing in the coming year, we will see increased activity in the development of the key IP necessary to support customers designing into this state-of-the-art production technology." 4.Any other matters that need to be specified: None Exhibit 99.4 Change in Juristic-Person Director 1.Date of occurrence of the change: 2004/02/04 2.Name and resume of the
