The semiconductor industry, in which UMC operates, is characterized by cyclicality and seasonality. UMC's revenue is significantly influenced by the communications segment (smartphones), which typically accounts for 45-50% of sales, and the consumer segment, contributing another 25-30%. Lows in orders and revenues for the semiconductor industry often occur in the first half of the year due to customer inventory corrections. To mitigate this volatility, UMC is strategically increasing its exposure to more stable and faster-growing markets such as automotive and IoT, which currently represent about 15-20% of its revenue.
