SK hynix Inc.

SK hynix is one of the two dominant global suppliers of DRAM and NAND flash memory, and — crucially for the AI cycle — the market leader in high-bandwidth memory (HBM), the specific memory that sits alongside every hyperscaler GPU. It just landed its US-listed American Depositary Shares (July 2026 IPO at $149) into a memory market that is genuinely tight.

• The operating story is unmistakable: Q1 revenue grew 198% year-over-year with 71% operating margins and 68% gross margins — that's HBM-heavy mix pricing power, not a normal memory cycle, and the last four EPS reports beat consensus by 19-71%.
• The supply picture backs the bull case, not the cyclicality bears: CEO Kwak has called HBM 'sold out past 2030', NVIDIA's incremental commitments jumped from roughly $119B to $279B (mostly memory), and a fresh $4B Indiana HBM4E packaging plant just broke ground to put in-country supply near the customer.
• The valuation is the standout: at a forward P/E under 5x with roughly 33% return on invested capital, the market is still pricing this like a commodity DRAM cyclical rather than an AI-cycle winner — Needham's $220 target reflects where the sell side is starting to land now that the ADS trades.
• The obvious risk is the exact one the bulls are dismissing: memory really is cyclical, and HBM pricing sits at the top of the stack — a demand pause from any of the top three hyperscalers would show up in ASPs before it shows up in units, and the multiple would compress the same day.

The path if it works is another quarter of HBM-driven margin expansion plus visible progress on the Indiana plant timeline — the multiple rerates toward Needham's $220 as global funds add the AI-memory pure play. The risk is a 2027 order push-out from a hyperscaler at a moment when the tape has fully accepted the 'sold out past 2030' line; that's how a low-multiple compounder becomes a normal cyclical again.
