Analysis of the Impact of AI Boom-Driven Memory Chip Price Hikes on Samsung Electronics and Industry Cycles

• Samsung Electronics’ current stock price is 138,900 KRW (+0.58%) [0]; market capitalization is approximately 928.7 trillion KRW [0].
• The company will announce its Q4 2025 fiscal year results on January 29, 2026 (previously the market expected an initial release on January 8; subject to official disclosure) [0].
• According to reports, analysts expect Q4 operating profit to increase by approximately 160% year-on-year against the backdrop of AI-driven memory price hikes (subject to official company disclosure) [1].
• Relevant reports indicate that TrendForce predicts the average price of DRAM (including HBM) will rise by 50%-55% in Q4 2025 compared to the previous quarter [2], and some channels also mention obvious upward price pressure.

• Reports citing Micron’s financial report and industry analysis state that AI servers have strong demand for memory, and some investment banks/institutions mention the risk of a ‘worst-ever shortage’ in 2026 [1].
• HBM Demand and Process Characteristics:
  • AI servers have high combined HBM and DRAM configuration per unit (example in reports) [1].
  • HBM manufacturing consumes more wafers (reports mention the process and yield background where ‘producing 1GB of HBM sacrifices approximately 3GB of DDR’) [2].
• Pre-order Lock-in and Tight Orders:
  • Reports state that Micron publicly said HBM inventory for calendar years 2025 and 2026 is sold out; Samsung and SK Hynix have orders exceeding production capacity [2].
  • Other reports indicate that HBM orders for 2026 are fully booked, and 2027 orders are filling up quickly [1].

• DRAM/HBM Prices: TrendForce predicts the average price in Q4 2025 will rise by approximately 50%-55% compared to Q3 [2].
• Consumer Electronics and End Markets:
  • Reports say some channels expect memory prices to rise by another 40% in H1 2026, putting pressure on end devices like smartphones; some brands may balance market share and profits [1].
  • Institutions like Counterpoint believe that brands with limited resources will face greater cost pressure [1].

• The traditional ‘inventory-price’ cycle is strengthened by high-intensity, long-cycle AI data center demand, significantly extending the time window of tight supply-demand balance [1][2].
• ‘Zero-sum game’ capacity allocation: More wafers are used for high-value HBM, suppressing the growth rate of traditional DDR supply and forming a structural constraint of ‘AI consuming capacity’ [2].

• Q4 2025 Market Consensus Expectations (To Be Verified):
  • Revenue: 89.82 trillion KRW; EPS: approximately 2,270 KRW [0].
  • Reports say analysts expect operating profit to increase by approximately 160% year-on-year [1].
• Latest Quarter (Q3 2025):
  • EPS: 1,826.78 KRW (exceeded expectations by +29.7%); Revenue: 86.06 trillion KRW [0].
• Financial Health:
  • P/E: ~28.56x, ROE: ~8.39%, Net Profit Margin: ~10.38%, Current Ratio: 2.51 [0].

• TTM Period Returns: 6 months +119.43%, 1 year +148.48% [0].
• 2025 Full Year (Jan 2, 2025 to Jan 6, 2026) cumulative increase of approximately +163.57% (based on interval price statistics) [0].
• (Note: Daily series for the 12 consecutive months before Jan 6, 2025 not obtained; thus no precise ‘past 12 natural months’ price change statement.)

• HBM Market Share (Q3 2025): SK Hynix ~53%, Samsung ~35%, Micron ~11% [3].
• HBM4 and Technology Progress:
  • Reports say Samsung is delivering HBM4 samples to customers and plans to mass-produce in 2026 [3].
  • Co-CEO said in an internal speech that customers gave positive feedback on HBM4’s ‘differentiated competitiveness’, and the market interpreted this as ‘Samsung is back’ [4].
  • Reports cite industry information that Samsung’s HBM4 performed top in speed in Broadcom’s SiP tests, and its thermal management also received good reviews [5].
• Supply Cooperation with NVIDIA:
  • Reports indicate that the two parties are ‘closely negotiating’ HBM4 supply, and customer certification and cooperation progress are continuing [3][4].

• The ‘3-4 year cycle’ previously dominated by consumer electronics, PCs, and mobile phones has been significantly extended and strengthened by long-cycle AI data center demand; capacity rigidity cannot be quickly matched in the short term [1][2].

• The three major manufacturers (Samsung, SK Hynix, Micron) are tilting capital expenditure toward HBM and advanced processes; the transformation and exit of old production lines have slowed the growth rate of traditional DRAM supply [1][2].
• Reports say Micron, Samsung, and SK Hynix are closing or cutting old capacity lines to tilt toward HBM, which has limited effect on alleviating general memory shortages [1].

• Large cloud vendors and NVIDIA, etc., lock in capacity for the next few years through long-term agreements, moving the spot market toward ‘futures-like’, pushing up lock-in premiums and bargaining difficulty [2].

• Smartphone/PC/automobile manufacturers need to accept higher costs or reduce configurations to offset; low-margin brands are under greater pressure [1][2].

• HBM Market Share: Samsung ~35% in Q3 2025, lagging SK Hynix’s 53% [3].
• Main Gap: SK Hynix is relatively leading in mass production and customer certification rhythm; Samsung is catching up in HBM4 and next-generation products [3][4].

• Vertical Integration Capability: IDM model (design-manufacturing-packaging testing) + foundry collaboration, with good conditions for process evolution and yield improvement [3][5].
• Customer Base and Ecosystem:
  • Reports say Samsung signed a relevant $16.5 billion cooperation with Tesla in 2025; HBM4 cooperation with NVIDIA continues to advance [3][4].
• Technology and Products:
  • Reports indicate that Samsung’s HBM4 has outstanding speed and thermal performance in third-party tests [5].
  • Continuing to advance HBM4 mass production planning for 2026 [3][4].

• Competitor Rhythm: SK Hynix still has first-mover advantages in customer certification and mass production rhythm; Micron is also accelerating and has obtained NVIDIA’s partial platform certification [1].
• Yield and Capacity Ramp-Up: HBM4 has more stacking layers and higher complexity; yield is still in the ramp-up stage, and there are uncertainties in expansion costs and time cycles [2].
• Market Expectations and Volatility: Current valuations already reflect high growth expectations; if customer adoption rhythm or capacity release is lower than expected, stock price volatility may increase [0].

• Neutral Scenario (High Probability):
  • HBM4 mass-produced as scheduled in 2026; customer certification progresses smoothly; HBM share gradually moves from ~35% to 40%+.
  • Memory prices remain high or continue to rise in 2026; profits and cash flow improve.
• Optimistic Scenario:
  • HBM4 performance and yield exceed expectations; obtain larger share orders from NVIDIA/Google/hyper-scale cloud vendors, etc.
  • Memory prices continue to rise beyond expectations; profit elasticity is further released.
• Downside Risks:
  • AI capital expenditure rhythm slows or capacity ramp-up is lower than expected; prices and orders are under pressure.
  • Geopolitical/competition/exchange rate and other factors drag down profit margins and order fulfillment.

• AI-driven high-value demand is reshaping the memory cycle: longer cycle, higher price volatility, clearer tight supply-demand balance [1][2].
• Price center shifts upward in 2025-2026; consumer electronics and end devices rebalance between cost and pricing [1][2].
• Sectors and Market: Technology sector fell slightly (-0.31%) on the day; industrials and finance led gains [0]; valuation differentiation of tech stocks intensified.

• Advantages: IDM comprehensive strength, HBM4 technology progress, customer base, and capital expenditure tilt [3][4][5].
• Risks: Competitive rhythm, yield and capacity ramp-up, valuation and expectation management [2][5].
• Observation Points:
  • Q4 results on Jan 29, 2026 and 2026 guidance (capital expenditure, HBM4 roadmap).
  • Order and certification progress from NVIDIA and hyper-scale cloud vendors.
  • Traditional DRAM supply-demand and price trends.

• Short-term: Performance and guidance are key verifications; if they meet or exceed expectations, they will support the market’s pricing of ‘AI memory leader’s comeback’.
• Mid-term: HBM4 mass production and share increase are core indicators; the trinity of technology/yield/customer determines whether it can move from ‘second’ to ‘on par with first’.
• Risk Control: Pay attention to valuation and expectation gaps, AI capital expenditure rhythm, geopolitical and competitive trends.
