全球存储技术：三星一季度业绩乐观后对存储市场更乐观

Weekly theme: more optimistic on memoryfollowing Samsung’s upbeat 1Q results Price Objective Change 10 April 2026 Why Samsung’s upbeat 1Q results can be a highlightWe believe that Samsung Electronics’1Q26 preliminary OP (W57tn: ~3x QoQ increase or ~9x YoY on the back of very strong DRAM and NAND ASP) confirmed a memory super-cycle. As such, we expect upbeat memory results and bullish guidance during the 1Qearnings season (2H April). EquityGlobalTechnology Simon Woo, CFA>>Research AnalystMerrill Lynch (Seoul)+82 2 3707 0554simon.woo@bofa.com Hynix ready todeliver super-cycle earnings; raise POWe raise our POon SK Hynix to W1,650,000 from W1,400,000 following +20%/+19% EPS revisions for 2026/27E. This is based on 13-15% higher ASP assumptions forDRAM/NAND to be consistent with Samsung’s upbeat memory chip prices. We are stillusing a fair P/E of 2026-27E 7x (unchanged), but our PO implies more than 50% upsidepotential. Like Samsung, we expect a few/several times larger OP in 1Q/2Q/3Q/4Q26(W40tn/55tn/61tn/62tn) vs previous peak cycles or W200tn+ pa in 2026-28 even withstable ASP (or slightly down) through 2H26 and 2027-28.

Two reasons: (1) we have already reflected upbeat 1Q26 sales(NT$49bn–up 7x YoY) in our previous earnings model update, and (2) we still assumestable ASP (limited increase) for 2H and 2027 after the 2H25-1H26 upturn period(Nanya Tech’s DRAM ASP: already +65% QoQ in 1Q and then +30% in 2Q, according toour new analysis). Thus, our PO (NT$400; target 2026-27E P/E still 11x, but higher thanKorean memory peers as a pure legacy DRAM play). Matt Shin>>Research AnalystMerrill Lynch (Seoul)matt.shin2@bofa.com Exhibit1:Memorysuper-cyclecontinues;3x sales YoY expected in 2026BofA global memory forecasts DRAM spot pricemuted, but 2Q ASP still risingDRAM spotprices have fallen for three consecutive weeks, and even NAND recently. However, 2Q DRAM/NAND ASP (still 50%+ lower than spot) will likely rise further by30%+/- QoQ amid well-negotiated contract prices. True, DRAM/NAND spot prices areexpected to decline further for the rest of 2Q or in 2H, but we believe it is too early tosee a hard-landing (just soft-landing at sub-10% MoM drop) on tight supply (ofcommodity memory) or capacity shift to HBM4e, LPDDR5, GDDR7, etc. Raise global memory forecasts using 10%+ higher ASP We raise our2026-28 global DRAM/NAND sales forecasts by 10%+/18%+ using 10%+higher ASP vs our earlier assumptions. This is just a follow-up action to reflect memorychipmakers’recently confirmed upbeat ASP for 1Q/2Q26 (up 100%+/- vs 4Q25). OurQoQ ASP assumptions for 2H26 (slightly up) and 2027 (slightly down) remain largelyunchanged. That said, our industry model reveals a few times larger annual market sizesfor 2026-28 (DRAM: US$400bn+; NAND: US$240bn+; vs sub-US$100bn in 2018/2024-25 peak periods). This should warrant high margin/ROE profile for almost all memorychipmakers. See Exhibit 3 for our global memory forecast summary.

We assume strong growth in 2026 sales (US$81bn; +136% YoY)driven by solid ASP growth (+31% YoY)and robust bit growth (+80%). Hynix’s proven 12-hi HBM3e and HBM4 (mass production started in 4Q25) should be the key contributors; industry averageOPM near 50% thanks to Hynix’s high margin profile (60%+); no downturn in 2027 given volume growth and cost reduction fully offset price cut.Global HBM market – record high revenue continues into 2027E (US$110bn) Global HBM market share by company SK Hynix–HBM earnings outlook stillstronger than Samsung’s GPU spec tables Exhibit26:10-30% HBM contentgrowth observed in AMD GPUs aswell led by MI350X
