UMC Reports Third Quarter 2023 Results

United Microelectronics Corporation (NYSE: UMC; TWSE: 2303) (“UMC” or “The Company”), a leading global semiconductor foundry, today announced its consolidated operating results for the third quarter of 2023.

Third quarter consolidated revenue was NT$57.07 billion, increasing 1.4% QoQ from NT$56.30 billion in 2Q23. Compared to a year ago, 3Q23 revenue declined 24.3% YoY from NT$75.39 billion in 3Q22. Consolidated gross margin for 3Q23 was 35.9%. Net income attributable to the shareholders of the parent was NT$15.97 billion, with earnings per ordinary share of NT$1.29.

Jason Wang, co-president of UMC, said, “During the third quarter, despite a 2.3% decrease in wafer shipments, quarterly revenue and gross margin remained firm QoQ which primarily attributed to the demand strength in computing and communication segments, continuous product mix enhancement as well as favorable currency movement. From end markets perspective, strength in computing applications were propelled by LCD controller, WiFi, codec and touch IC controllers while shipments in communication segments increased due to demand for RF front end IC and networking chips. Looking back at 2023, although foundry industry experienced a significant decline in market demand, UMC maintained solid structural profitability supported by firmness in blended ASP due to continuous product mix optimization efforts and the increasing contribution from specialty technologies. As UMC continues to introduce new specialty technologies to solidify our differentiation, we will strengthen the competitiveness of our customers and enhance their respective market position.”

Co-president Wang said, “For the fourth quarter, with the recent rush orders from PC and smartphones, we expect demand has gradually stabilized. However, customers still employ a cautious and conservative approach in maintaining lean inventory levels while automotive business conditions appear challenging. For 2024, we anticipate the production ramp of our 12A Phase 6 fab will further enhance revenue contribution from 22/28nm continuing the robust business traction for UMC. In addition, through our technology leadership, we will ramp up our offering on 22nm derivative products which will further our specialty technology product pipeline.”

Co-president Wang continued, “Talent is UMC's most important and highly valued asset. We respect the uniqueness of every employee and are committed to creating a diverse, equal, and inclusive workplace environment. Receiving the ‘HR Asia’ award for the ‘Best Employer in Asia’ in July is a recognition of our years of effort. Our goal is to create a culture of diversity and inclusivity in our workplace that enables employees to leverage their strengths, thereby playing a pivotal role in the Company's sustained growth and enduring success.”
