메모리 반도체 관련주는 SK하이닉스의 실적 발표가 HBM 수요 증가를 견인한 것으로 나타나면서 주목받았다.

Memory is back in the spotlight after SK Hynix reported record Q3 numbers, with revenue up 328% year over year and operating profit up a very large multiple. AI demand for HBM and DDR5 is tightening supply through 2030, and that kind of squeeze can reshape where capital flows next. This article walks through three stocks exposed to the same news, outlining where some investors may see opportunity and where others might prefer caution.

The stocks covered below are only a small sample of the idea. The full screen surfaced 34 more memory and HBM leaders with equally compelling business stories that are not covered here. To quickly identify where your own thesis lines up, use the Global Memory & HBM Semiconductor Leaders screener to filter, analyze, and pinpoint the highest-conviction plays.

**Wonik IPS (KOSDAQ:A240810)**

Wonik IPS builds front-end semiconductor equipment used in DRAM, NAND and HBM fabs, which ties it directly into the Global Memory & HBM Semiconductor Leaders theme. Almost all of its revenue, about ₩943 billion, comes from the semiconductor equipment segment, and the business carries a market value of roughly ₩4.3 trillion.

Wonik IPS provides focused exposure to memory fab equipment at a time when AI-related DRAM, NAND and HBM demand is directing more capital toward front-end tools. Earnings and revenue expectations are consistent with that memory capex narrative, but one key unknown factor may significantly influence those returns.

That unknown could be decisive. Step through the DCF valuation analysis for Wonik IPS to see how different memory capex paths might reshape what the company is really pricing in.

**Powertech Technology (TWSE:6239)**

Powertech Technology runs a global IC back-end operation that packages and tests DRAM, NAND and HBM devices for memory suppliers, tying it directly into the Global Memory & HBM Semiconductor Leaders theme. All of its revenue, about NT$85.8 billion, comes from semiconductors, and the stock carries a market value near NT$189.1 billion.

Powertech Technology provides exposure to the packaging and test link in the memory chain, where AI-driven demand for HBM and DDR products feeds into DRAM and NAND volumes. The business combines that role with a large semiconductor revenue base and higher forecast earnings, although the effect of one pressure on cash generation could be important for investors focused on sustainability.

To see how that cash pressure plays through Powertech Technology, review the analysis report and the headline numbers to understand what they might be masking.

**Phison Electronics (TPEX:8299)**

Phison Electronics gives this screen direct exposure to the flash memory controller layer that sits between raw NAND supply and AI-hungry storage systems. This is why its push into AI-centric platforms matters for anyone tracking where memory value pools are shifting.

Phison Electronics designs flash memory controllers and related systems that underpin SSDs and storage devices tied to NAND demand in AI servers, data centers and advanced computing. The business generates about NT$149.8 billion from flash memory control chip design and has a market value near NT$426.8 billion.

"Commercial deployments of Phison Electronics' AI data platform into more than 10 banks, over 30 hospitals and 20 small and medium enterprises, together with management's target of securing over 100 new commercial AI data platform customers across banks, government, enterprise, hospital and education by year end, point to aiDAPTIV and related software platforms moving from project revenue to a wider recurring on-premise AI services base that could lift net margins and earnings quality beyond what current models imply."

What really decides how far that upside carries is how one quiet shift in the mix between hardware and higher-margin services actually plays out.

That quiet shift is exactly where Phison Electronics could be mispriced. The full narrative for Phison Electronics unpacks how an accelerating services tilt might reshape the story for patient holders.
