No Downgrade in HBM Capacity Upgrades as Memory Spot Prices and Capital Returns Jointly Strengthen Industry Conditions
BofA expects HBM content per unit and ASPs to continue rising from 2H 2026 through 2027, with strengthening DRAM and NAND spot prices, and sees Samsung, SK Hynix, Phison, and Silicon Motion benefiting from the memory supercycle.
- HBM capacity requirements for next-generation GPUs such as Rubin Ultra are not expected to be downgraded, with HBM4e/HBM5 potentially configured with 500—1,000GB in 2027—2030.
- HBM4 delivery prices in 2H 2026 have shown signs of a 10%—20% increase, alongside demand for pull-ins from 1H 2027.
- Spot prices for both 16Gb DDR4 and DDR5 rose 2% during the week, while NAND spot prices rose more sharply, with 1Tb products up around 10% week over week.
- Samsung and SK Hynix may bring forward dividends and buybacks, with the report basing shareholder-return estimates on 50% of 2026 free cash flow.
- Phison and Silicon Motion are expanding NAND inventory and enterprise-solution capabilities through convertible bond financing; financing dilution and R&D investment are near-term trade-offs.
Report interpretation
Overview
This report focuses on the global memory upcycle. Its core view is that AI-driven HBM capacity upgrades, rising DRAM and NAND prices, and improving capital returns by memory manufacturers will jointly support industry earnings from 2H 2026 through 2027. The report also reviews the results and convertible bond financing arrangements of Phison and Silicon Motion.
Core views
For HBM, the report disagrees with the view that new GPUs will materially reduce HBM configurations: the HBM4e/HBM5 roadmap already points to 500—1,000GB capacities, 8-hi TSV capacity has shifted to 12-hi in 2H 2026, and memory performance of Rubin Ultra declines materially at 288—500GB capacities. On pricing, the report observed a 10%—20% increase in HBM4 delivery prices in 2H 2026. In conventional memory, tight supply has driven DRAM prices higher for 18 consecutive weeks, while NAND spot-price gains have exceeded expectations.
Analysis framework
The report cross-validates product-specification roadmaps, HBM stacking and TSV supply conditions, spot and contract price trends, South Korean semiconductor exports, Chinese IC imports, monthly sales of Taiwanese companies, company earnings, and valuation multiples.
Methodology notes
Assessing memory-sector conditions through spot prices, contract prices, chip supply, and end-demand.
The report evaluates industry earnings elasticity using DRAM and NAND price trends and the degree of supply tightness.
Assessing AI-chip memory configuration trends through HBM generations, stack counts, and TSV capacity.
The 12-hi/16-hi technology roadmap and Rubin Ultra's performance requirements are the main grounds for the view that HBM content will not be downgraded.
Deriving target prices from expected 2027—2028 EPS and target P/E multiples.
The report applies different forward P/E multiples to Phison, Samsung, Silicon Motion, and SK Hynix, comparing them with historical cycles and peer-company ranges.
Asset mapping & comparison
Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).
- Phison Electronics (8299 TT)Beneficiary of NAND controllers, enterprise SSDs, and AI ecosystem modules
- Strengths
- 2Q26 revenue reached a high level; AI ecosystem modules accounted for 38% of revenue; secured NAND procurement and growth in enterprise solutions provide support.
- Weaknesses
- A substantial rise in R&D expenses offsets part of the revenue and gross-margin improvement; issuance of US$0.8bn in convertible bonds results in approximately 3% dilution.
- Comparison
- Target price of NT$4,000, equivalent to 24x P/E of expected 2027—2028 EPS, above its historical mid-to-high teens range.
- Risks
- An unexpected decline in NAND prices, weakening demand, margin pressure, and financing dilution.
- Samsung Electronics (SSNLF / SSNHZ)Global leader in HBM, DRAM, and NAND, benefiting from the memory supercycle and shareholder returns
- Strengths
- Covers multiple memory-product categories and has potential for free cash flow generation, special dividends, and buybacks.
- Weaknesses
- EPS growth may slow after 2026; the company must contend with global memory supply expansion and competition.
- Comparison
- Common share target price of W550,000; preferred share target price of W375,000, with the latter's discount to common shares potentially providing a higher dividend yield.
- Risks
- Capex cuts by U.S. mega-cap technology companies, memory oversupply, competition from Chinese manufacturers, and loss of market share.
- Silicon Motion (SIMO)Beneficiary of NAND controllers and enterprise storage solutions
- Strengths
- Strong growth potential in enterprise-solution orders; financing proceeds can support inventory and business expansion.
- Weaknesses
- High exposure to commoditized NAND and PC and smartphone memory demand; issuance of US$1.0bn in convertible bonds.
- Comparison

- SK Hynix (HXSCF / SKHY)Core beneficiary of high-end HBM and DRAM supply
- Strengths
- Globally leading high-margin DRAM and HBM positioning; the report expects earnings to reach new highs in 2027—2028, with a possible increase in the buyback allocation.
- Weaknesses
- The share price is relatively volatile, and the market may become concerned early about a downturn in 2027 or 2028.
- Comparison
- Target price of W3,000,000, based on 8x P/E of expected 2027—2028 EPS, below the reasonable 9—11x range for global DRAM peers.
- Risks
- AI-chip demand weaker than expected, capex reductions by U.S. mega-cap technology companies, and oversupply from capacity expansion in 2026—2027.

Impact & implications
If HBM content and selling prices rise simultaneously, leading companies with advanced HBM, DRAM, and NAND supply capabilities will gain stronger revenue and earnings leverage. Rising spot prices can improve inventory values and near-term pricing power, while high free cash flow may translate into dividends and buybacks. For controller vendors, enterprise SSD and AI-solution demand creates growth opportunities, but convertible bond financing, R&D investment, and NAND price volatility will affect earnings realization.
Risks
- Unexpected cuts in AI capital spending by U.S. mega-cap technology companies or cloud providers.
- Following increased capital expenditures in 2026—2027, the global memory market may experience oversupply.
- A sharper-than-expected correction in HBM, DRAM, or NAND prices.
- Intensifying competition from Chinese and other competitors, or loss of market share by industry leaders.
- Geopolitical factors such as tariffs and export restrictions disrupting supply chains and end-demand.
- Convertible bond financing, inventory expansion, and R&D investment by Phison and Silicon Motion may pressure near-term returns.
What to watch
- Capacity specifications, pricing, and pull-in activity for HBM4 in 2H 2026 and for HBM4e/HBM5 after 2027.
- Whether DRAM and NAND spot and contract prices can continue rising, and whether supply tightness eases.
- South Korean semiconductor exports, Chinese IC imports, and monthly sales data across Taiwan's memory supply chain.
- Samsung's special dividend and buyback timetable, as well as SK Hynix's free-cash-flow distributions and buyback arrangements.
- Phison's enterprise and AI ecosystem module revenue mix, R&D expenses, and NAND inventory strategy.
- Silicon Motion's enterprise-solution orders, use of convertible bond proceeds, and gross-margin performance.
