Analysis
Q4 CY2023 (Oct-Dec 2023): SUMCO reported ¥95.4B (~$650M) quarterly revenue. Full year CY2023 revenue ¥398.6B (~$2.8B). Semiconductor market still in downturn for consumer/memory, but AI chip demand was now a clear structural driver. TSMC N3 ramping for AI applications alongside Apple. HBM production expanding rapidly — all three DRAM makers adding HBM3 capacity. NVIDIA H200 announced, data center GPU backlog at record levels. SUMCO's AI wafer attribution growing as the share of leading-edge 300mm wafer starts dedicated to AI chips increased. Math: 75% from 300mm x 23% leading-edge x 23% AI share = ~4.0%. ¥95.4B x 4.0% = ~¥3.8B (~$26M) estimated AI revenue. Full year: ¥398.6B x 3.4% (weighted average) = ~¥13.6B (~$96M).
