The Memory Boom’s Real Winner Isn’t Just SK hynix

SK hynix stock: record Q3 2026, memory sold out through 2029. Can capacity keep up without a glut? In this video: SK hynix’s Q3 2026 results and outlook, how 4F² and 3D DRAM let memory makers get more bits from existing fabs, and why equipment makers like Lam Research remain the durable bottleneck. Sponsored by Fiscal.ai — see disclosure in the sponsor block below. SK hynix posted a record quarter. Revenue topped 100 trillion won, up 32% quarter over quarter and 328% year over year. Operating profit reached 83 trillion won. Management says DRAM and HBM are effectively sold out through 2029 under long-term agreements. With new fabs not ramping meaningfully until 2028, the near-term bit growth has to come from upgrading existing clean rooms (6F² refinement, 4F², and eventually 3D DRAM). That strengthens the case for the Fab Five equipment makers.
