Short-term negatives may have largely been released, while SK hynix's medium-term recovery thesis remains intact

Overview

The report analyzes key investor questions following the recent sharp correction in SK hynix's share price, focusing on HBM content and pricing, the timing of shareholder returns, the ₩54 trillion infrastructure investment, and Solidigm's potential U.S. listing. J.P. Morgan believes that normalization of HBM content is a necessary step to ease excessive chip shortages, and that the market's interpretation of a steep discount is inaccurate; the large investment is mainly for long-term fab and capacity preparation. As the company is set to update shareholder returns, HBM contract prices, and Solidigm's listing plan in the near term, market sentiment is expected to gradually improve over the medium term.

Core views

The bullish thesis is built on three points: first, execution capabilities in AI solutions have significantly improved SK hynix's profitability, and the company remains in the early stage of a memory upcycle, with improving fundamentals in conventional DRAM and NAND amplifying earnings leverage in its pure memory business; second, short-term HBM pricing is not the only objective, as the company can optimize its product mix between HBM and higher-margin long-term agreements for DDR5, LPDDR5, and NAND in conjunction with multi-year procurement relationships with important customers such as NVDA; third, improving future cash flow provides a foundation for increasing shareholder returns, while the financing necessity and strategic benefits of a Solidigm listing are relatively limited. The report believes most recent negative factors have been priced in by the market, and subsequent catalysts are expected to drive valuation recovery.

Analysis framework

The report uses a combination of event-driven analysis and earnings valuation: it evaluates the impact of recent market rumors and company disclosures on HBM prices, capacity, capital expenditure, cash flow, and shareholder equity item by item, and sets a June 2027 target price using a 7x P/E multiple on average FY26E to FY27E earnings per share. The analysis also compares SK hynix with Japanese and U.S. memory peers in terms of shareholder return expectations, and assesses the strategic value of a Solidigm listing from the perspectives of financing needs, duplicate listing rules, and investor base.

Methodology notes

• Valuation methodsForward P/E valuation method

  FY26E to FY27E average earnings per share multiplied by a 7x P/E multiple

  The target price of ₩2,750,000 reflects the research's positive view on the strength and duration of this memory upcycle, as well as the sustainability of SK hynix's profitability improvement over the next three years.

  The report views multiple company updates around the end of September 2026 as key triggers for market repricing, while also examining capital expenditure and end-demand risks.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• SK hynix (000660.KS)

  Core recommended stock

  Strengths

  Strong execution capabilities in HBM and AI solutions, high earnings leverage from the memory upcycle, and improving cash flow that can support capital expenditure and shareholder returns.

  Weaknesses

  Business is concentrated in highly cyclical memory products, capital expenditure is large, and the market is highly sensitive to HBM pricing and shareholder returns.

  Comparison

  Compared with Japanese and U.S. memory peers, investors expect it to make stronger shareholder return commitments given its stronger earnings and asset monetization capabilities.

  Risks

  DRAM prices and margins falling below expectations, deterioration in end demand or inventory, HBM contract prices falling short of expectations, and concerns over shareholder dilution caused by capital allocation or subsidiary listing.

• Solidigm

  SK hynix's enterprise SSD and NAND subsidiary

  Strengths

  Benefits from the AI-driven NAND upcycle; the report states that its margin performance is strong, and it has enterprise SSD and QLC solution capabilities.

  Weaknesses

  It recorded losses in 2023, and a potential independent listing could complicate the interest structure.

  Comparison

  Compared with remaining internally held by SK hynix, a U.S. listing is viewed as offering limited incremental benefits in financing, expanding the investor base, and valuation re-rating.

  Risks

  A potential listing may involve duplicate listing rules, dilution of existing shareholder interests, and weakened strategic synergies.

• Kioxia (285A.T)

  Asset related to SK hynix's shareholding and potential source of cash

  Strengths

  Sale of the relevant stake could enhance SK hynix's cash generation and shareholder return capacity.

  Weaknesses

  Asset value and disposal gains are affected by the NAND cycle and market prices.

  Comparison

  Its asset monetization capability leads investors to expect stronger shareholder returns from SK hynix than from some memory peers.

  Risks

  Uncertainty exists around the timing of sale, valuation, and use of proceeds.

• HBM pricing assumption2027 year-over-year increase below 40%This is J.P. Morgan's relatively conservative assumption; the report rejects rumors of a 50% discount versus competitors
• Shareholder return update timingBefore the end of the third quarter of 2026Earlier than management's previous indication of an update before year-end

Impact & implications

If the shareholder return plan is progressive and the scale of commitment meets investor expectations, while HBM contract prices do not show the steep discounts feared by the market, recent valuation headwinds could ease quickly. Although long-term capital expenditure is large in scale, the new fabs will come online relatively late, and in the short term it is more about fab preparation than immediately increasing supply, so the impact on the current memory cycle is limited. If demand for DRAM, NAND, and HBM continues to be driven by AI investment, SK hynix, as a pure memory vendor, may demonstrate greater earnings and share price leverage.

Risks

• DRAM prices and margins are lower than expected.
• End demand is weak or industry inventory is higher than expected.
• HBM contract prices or average selling price increases are lower than the research assumptions.
• Large-scale infrastructure investment leads to lower returns on capital or pressure on free cash flow.
• The shareholder return plan falls short of market expectations.
• Solidigm's listing causes dilution of existing shareholders, duplicate listing controversies, or impaired strategic synergies.
• The subsequent ramp-up schedule of new wafer fabs does not match demand growth, creating the risk of oversupply.

What to watch

• The shareholder return plan and specific commitment scale to be announced before the end of September 2026.
• HBM contract price updates before the end of September 2026.
• Review results for Solidigm's U.S. listing plan within the next month.
• The difference between actual HBM4 pricing and competitors, and the 2027 average selling price increase.
• Groundbreaking, investment pace, and capacity release arrangements for the Yongin Y2 and Cheongju M17 projects.
• Changes in DRAM and NAND average selling prices, margins, end demand, and inventories.
• Progress on multi-year procurement and long-term agreements between SK hynix and core customers such as NVDA.
