Report Interpretation

Overview

This report summarizes operating information on SK Hynix obtained during the UBS Korea Summit, focusing on shareholder returns, long-term supply agreements, HBM and DRAM supply-demand dynamics, capacity expansion, and valuation. UBS believes demand visibility and shareholder returns are both becoming more favorable and reiterates its Buy rating despite capital expenditure remaining elevated over the long term.

Core views

On shareholder returns, SK Hynix indicated that the previously announced Won40tn share repurchase plan forms part of its overall free cash flow return policy. The policy wording changed from “up to 50%” to “more than 50%,” implying that 50% is a return floor rather than a ceiling during 2025—2027. The company may also conduct additional repurchases within this framework when support for the share price is needed and would make a clear announcement. Further details are expected during the 3Q26 earnings call. Regarding the ADR, the company will proceed with regulatory approvals and may gradually improve the liquidity of its US-listed securities. Regarding long-term agreements, although the company did not quantify the final coverage ratio, UBS maintains its view that more than 50% of bit volume will be covered by long-term agreements by year-end. The agreements primarily improve sales-volume visibility and do not establish price floors or ceilings. Negotiations prioritize hyperscale cloud customers, while large OEMs should also be included. This structure can secure a substantial portion of shipments, although pricing will continue to vary with market negotiations. HBM and DRAM supply-demand dynamics remain the core support. Given supply constraints, adjustments to HBM product specifications are possible; UBS believes Nvidia has shifted from HBM4E 12-Hi to HBM4 8-Hi for VR/R300. Memory capacity per SiP declines, but the number of required SiPs increases, leaving overall demand unaffected. The report expects HBM demand to remain exceptionally strong in 2027, with market undersupply potentially persisting through 2030 or beyond. The overall DRAM demand fulfillment rate may be only 60%—70%, with unmet demand continuing into 2027 and further intensifying the industry shortage. On pricing, SK Hynix's DRAM average selling price in 2Q26 was below that of its peer. UBS estimates its price at US$1.47 per Gb, versus US$1.55 for Samsung, and expects the gap to narrow in 2H26. Consequently, tight supply not only provides sales-volume visibility but may also improve the company's revenue and earnings performance as its average selling price catches up. Capacity expansion will continue to drive capital expenditure higher. Equipment installation for Yongin Phase 1 is expected to begin in February 2027, with the second cleanroom potentially following later that year; the first phase will remain focused on DRAM. On process technology, the company may continue using 6F² through the 0a nm node, although whether it is more suitable than 4F² remains to be confirmed. It may subsequently adopt 4F² across multiple nodes before transitioning to 3D DRAM. In NAND, the Dalian plant may expand capacity using floating-gate technology and gradually upgrade from 144/192 layers to 240 layers; mass production for the M17 NAND project is expected to begin in 1H29. UBS estimates capital expenditure will reach Won61tn in 2027, up 30% year over year, with elevated investment continuing for some time. Financial forecasts reflect the earnings leverage created by tight supply and demand. UBS forecasts 2026 revenue, EBIT, and net profit of Won357,816bn, Won280,617bn, and Won276,672bn, respectively, with diluted EPS of Won395,021. The corresponding 2027 forecasts rise to Won588,667bn, Won483,488bn, Won377,417bn, and Won598,302. UBS's EPS forecasts are above consensus: Won395,021 versus Won353,128 in 2026, Won598,302 versus Won463,642 in 2027, and Won735,840 versus Won493,869 in 2028. EBIT margins are expected to be 78.4% and 82.1% in 2026 and 2027, respectively, while free cash flow to equity yields are forecast at 15.0% and 25.1%, respectively. On valuation, UBS assigns SK Hynix a forward 12-month P/BV multiple of 4.32x based on long-term average ROE and the cost of equity; the key assumptions are a long-term ROE of 49.2% and a cost of equity of 11.4%. Accordingly, the 12-month price target for the common shares remains Won3,000,000, while the ADR price target is US$210. Relative to the reference share price of Won1,678,000, forecast price appreciation is 78.8%. Including a forecast dividend yield of 2.9%, forecast total return is 81.7%. Under an assumed market return of 9.2%, forecast excess return is 72.5%, supporting UBS's reiterated Buy rating. The short-term quantitative assessment is also favorable: the six-month industry structure score is 5, the regulatory environment score is 3, and the score for operating changes over the past 3—6 months is 5. The potential positive surprise score for the next EPS update relative to consensus is 5. Relative to UBS's own forecasts, the upside and downside earnings risk score is 3, indicating broadly balanced risks. The report also identifies positive catalysts over the next three months, with attention around 20260918 on monthly smartphone sales, the conclusion of pricing negotiations, Nvidia supply-chain feedback on GPU demand, and further information on shareholder returns.

Analysis framework

UBS first organizes management's comments at the summit regarding shareholder returns and ADR arrangements, then analyzes long-term agreement coverage, HBM product changes, DRAM supply-demand dynamics, and average selling price differences. It subsequently assesses the capacity and capital expenditure trajectory based on the Yongin, Dalian, and M17 projects and incorporates its operating views into revenue, earnings, and cash-flow forecasts. Finally, the report derives a forward 12-month P/BV valuation from long-term ROE and the cost of equity, while using a short-term quantitative questionnaire to identify earnings-expectation gaps and event catalysts.

Methodology notes

• Industry/Sector Analysis FrameworkSupply-demand framework

  HBM and DRAM supply-demand gap analysis

  The report assesses whether the memory market is in shortage based on the demand fulfillment rate, the duration of unmet demand, customer long-term agreements, and capacity constraints, and uses this assessment to explain the demand and earnings outlook for 2027.

• Industry/Sector Analysis FrameworkVolume-price decomposition

  Bit shipment visibility and average selling price analysis

  Long-term agreements primarily improve visibility into bit shipment volume but do not lock in prices. The report then compares SK Hynix's and Samsung's per-Gb prices to assess the differing effects of volume and price on revenue.

• Corporate Fundamentals and Financial FrameworkFree cash flow analysis

  Free cash flow shareholder return policy

  The report places the share repurchase within the framework of returning more than 50% of free cash flow during 2025—2027 to assess the minimum return ratio and scope for additional repurchases.

• Valuation MethodPB valuation

  Forward 12-month P/BV valuation

  Based on a long-term ROE of 49.2% and a cost of equity of 11.4%, UBS assigns a forward 12-month P/BV of 4.32x and derives the price targets for the common shares and ADR.

• Event Trading and Behavioral FinanceEvent-driven analysis

  Short-term catalyst assessment

  Using a quantitative questionnaire, the report evaluates the industry and regulatory environment over the next six months and the expectation gap for the next EPS update, while tracking smartphone sales, pricing negotiations, GPU demand, and shareholder return updates.

Impact & implications

The report believes that long-term agreements improve bit shipment visibility, while persistent HBM and DRAM shortages combined with a narrowing selling-price gap can support SK Hynix's earnings and cash flow for the next several years. Although capacity expansion will keep capital expenditure elevated, the floor of returning more than 50% of free cash flow reinforces shareholder return expectations and is a key basis for UBS maintaining its high price target and Buy rating.

Risks

• Although the DRAM industry is highly consolidated, it remains commodity-like and cyclical adjustments will continue to occur.
• DRAM and NAND demand is relatively sensitive to smartphone and tablet sales and product mix, and is also affected by enterprise spending on servers and solid-state drives.
• The memory industry is capital-intensive, and contract prices are renegotiated every two weeks to three months. Cash flow can therefore change rapidly, requiring adequate capital to be maintained.
• Improvement in the NAND industry structure is weaker than in DRAM, and capacity expansion by industry participants could still alter supply-demand dynamics.
• Over the long term, the industry may need to adopt new memory technologies to supplement or even replace existing silicon-based Flash and RAM architectures.

What to watch

• Watch for further details on free cash flow returns, additional repurchases, and ADR arrangements during the 3Q26 earnings call.
• Monitor whether the bit volume covered by long-term agreements can exceed 50% by year-end and the progress in including large OEM customers.
• Monitor whether the DRAM average selling price gap between SK Hynix and Samsung narrows in 2H26.
• Watch for monthly smartphone sales, the conclusion of pricing negotiations, Nvidia GPU demand supply-chain feedback, and shareholder return updates expected or clarified around 20260918.
• Monitor the start of equipment installation for Yongin Phase 1 in February 2027, construction of the second cleanroom, and progress on the Dalian and M17 NAND projects.
