SK hynix Went All In On HBM, And Paid For It With A Bruising Miss On Consensus Expectations For Q2’26, But Says It’s Integrating a “Cooling Element” Within HBM5

SK hynix’s Q2 2026 revenue and operating profit came in below consensus.

The miss was driven by a sales mix tilted toward HBM, which limited pricing upside near term.

The company remains upbeat on AI demand and is expanding DRAM, NAND, and next-gen HBM supply.

It plans to add a cooling element to HBM5 and rebalance some focus toward consumer and server memory.

Yongin Y1 and Y2 fab plans will shape future memory supply, pricing, and AI infrastructure capacity.
