Analysis
Q3 CY2023 (Jul-Sep 2023): SUMCO reported ¥98.7B (~$670M) quarterly revenue. Semiconductor downturn persisting in memory/consumer, but AI-related leading-edge demand was strengthening. TSMC reported HPC (including AI) at 42% of revenue in Q3 2023, up from 38% a year prior. HBM production was ramping significantly at SK Hynix and Samsung, pulling through incremental 300mm DRAM wafer demand. SUMCO's 300mm wafers now had slightly higher AI attribution due to: (1) TSMC increasing wafer starts for AI accelerators (H100/A100) at N4/N5, and (2) HBM DRAM production requiring dedicated 300mm wafer capacity that would not exist without AI demand. Conservative increase to 3.5%. Math: 75% from 300mm x 22% leading-edge share (growing) x 21% AI share of leading-edge (growing) = ~3.5%. ¥98.7B x 3.5% = ~¥3.5B (~$24M) estimated AI revenue.
