GF Securities – Memory Sector: Downturn Approaching, HBM Pricing Pressured

– We downgrade the entire memory sector and assign an Underperform rating on Micron (MU US), SK Hynix (000660 KS), and SanDisk (SNDK US).

◾+ Sector slowdown and demand weakening intensifying
– Following a bottom in 1Q23, the memory sector is projected to post XX consecutive quarters of improvement through 3Q25 — marking the longest upcycle since 2016.
– However, a downturn is increasingly likely starting from 4Q25. Key reasons include:
 1) Risk of a XX% tariff on electronics/semiconductors by the Trump administration
 2) Deteriorating global macro conditions → smartphone shipment growth to turn negative, PC shipments limited to +1~2%
 3) HBM pricing could also become a headwind

◾+ HBM and DRAM prices: Potential weakening from 3Q25
– As of CYQ2, memory pricing was stronger than expected (thanks to low smartphone inventories and preemptive restocking during the 90-day tariff waiver)
– 2Q25 DRAM/NAND contract pricing: QoQ +67% expected
– However, from 3Q25, price momentum is likely to slow due to weak demand and inventory pressure from servers and PCs:
 - Pricing increase of only around 0~5% or potentially flat
 - This flat trend may persist through 4Q25
◾+ Samsung’s entry to intensify HBM market competition
– Samsung is preparing to qualify HBM3e-12Hi with NVIDIA (possibly by June)
– NVIDIA is delaying 2026 HBM3e pricing negotiations pending Samsung’s qualification
– Samsung’s market entry in 2026 may trigger HBM4 price declines
 - Currently, HBM4 is priced at a XX% premium to HBM3e-12Hi
 - CXMT’s DDR5 production ratio also expected to reach XX% by end-2025
◾+ Stock preference
– 1st: Micron > 2nd: SanDisk > 3rd: SK Hynix
 - Micron: U.S.-based production → potential beneficiary of tariffs; gaining share in AMD/AWS
 - SanDisk: Focused on NAND → less exposed to HBM, relatively defensive
 - SK Hynix: Over XX% of DRAM revenue from HBM, but high exposure to HBM pricing pressure creates downside risk

✅ Conclusion: The memory sector is likely to peak in 3Q25, with a potential slowdown thereafter. HBM pricing headwinds and renewed U.S. tariff risk are expected to weigh on medium- to long-term valuations. Among covered names, Micron is viewed most favorably, while SK Hynix remains relatively conservative due to its large HBM exposure.
