SK hynix (000660) Report Interpretation

Overview

J.P. Morgan reiterates Overweight on SK hynix, viewing the company as a leveraged beneficiary of a durable AI-led memory upcycle. The report lowers its price target because it applies a lower valuation multiple, not because its underlying multiyear earnings outlook has weakened.

Core views

J.P. Morgan maintains a bullish view on SK hynix and the memory-industry outlook. Its central thesis is that stronger cloud-service-provider and AI-model-lab revenue signals improving returns on AI capital expenditure, supporting a higher-for-longer earnings cycle. The firm forecasts FY26E-28E EPS CAGR of 26% and argues that SK hynix's AI-solution execution has materially strengthened its earnings capacity. It views the company as positively positioned in an early memory upcycle because its pure-play memory exposure gives it higher operating sensitivity to improving conventional-memory fundamentals. The report places particular emphasis on the durability of long-term agreements (LTAs). SK hynix has reported LTAs with ten key customers, which J.P. Morgan estimates account for more than half of total volume and are largely cloud-service-provider and AI-memory customers. Although contract terms are not fully disclosed, the agreements may include floor prices, take-or-pay provisions, prepayments and ceiling-price terms. The contracts focus on server-compute products such as Server-DIMM, SOCAMM-LPDDR and enterprise SSDs, which carry higher pricing than consumer-grade memory. J.P. Morgan therefore expects the sales mix and continued contract-price increases to support ASP expansion over the coming year. For HBM, the report interprets customers' content adjustments as optimization rather than a reduction in total procurement demand. A migration back to 8Hi products is expected to raise output and reduce the supply-demand gap from 30-40% to 10-20%, while retaining a shortage-market structure. J.P. Morgan forecasts HBM bit-shipment growth of 30% in FY26E and 55% in FY27E. It assumes a 35% blended HBM ASP increase in FY27E, below bullish market expectations of 50-100%, and expects HBM operating margin to exceed 70% next year, ahead of FY24-25 levels. The firm views weaker DRAM pricing momentum in 2Q26 as a one-off effect of product-mix changes and price-hike recognition timing rather than an execution failure. It expects server DRAM ASP to move more strongly sequentially than peers and HBM4 to raise the blended DRAM ASP trend above the industry average in 3Q26E. SK hynix's NAND mix is also described as differentiated: enterprise SSD represents 70-80% of NAND sales, while its QLC solution is gaining traction relative to peers with slower ramps. J.P. Morgan estimates operating profit of W78trn in 3Q26E and W93trn in 4Q26E, broadly in line with consensus. It also highlights HBF, an AI-focused NAND technology with specified capacity of up to 512GB in a two-stack configuration and bandwidth offerings of 0.4-3.0TB/s, alongside an early-next-year mass-production target for V10 375-layer 4D NAND. The earnings outlook is revised upward. Relative to its May-2026 estimates, J.P. Morgan raises FY26E-28E EPS by 3-16%, with FY26E net profit helped mainly by the Kioxia stake-sale impact and FY27E-28E increases of 3-7%. The revisions reflect a stronger 2H26E DRAM ASP trend, a higher NAND ASP base after 2Q26, higher HBM ASP assumptions amid the industry supply-demand mismatch, and greater memory bit production from capacity pull-in and faster technology migration. The report raises projected FY26E-28E capex to W187trn from W175trn. For FY27E-28E, it assumes price stabilization as LTAs become a larger share of sales; inclusion of price-hike clauses in existing LTAs is identified as upside. The price target falls to W2,750,000 for Jun-27 from W3,000,000 for Dec-26 because J.P. Morgan cuts its target valuation to 7x average FY26-27E EPS from 8x. The report says a rerating from less than 4x forward P/E to 6x or more may take time, as the market now demands clearer capital-allocation delivery and stronger evidence that AI computing will sustain memory consumption. After a 46% pullback from the June peak, compared with declines of 30% for KOSPI and 33% for memory peers, the firm considers shareholder returns especially important. It expects an official capital-allocation and return-program update by year-end and regards a buyback announcement within the next couple of months as a potential catalyst.

Analysis framework

The report links AI capital-spending durability to cloud and AI-customer demand, then tests the earnings implications through LTAs, HBM supply-demand conditions, DRAM and NAND ASPs, product mix, shipment volumes and margins. It revises earnings assumptions and applies a forward P/E multiple to average FY26-27E EPS to derive the target price.

Methodology notes

  J.P. Morgan separates volume, pricing and mix effects to explain revenue, operating-profit and earnings revisions.

• Valuation methodsP/E and PEG Valuation

  Forward P/E valuation

  The Jun-27 target price is based on 7x average FY26-27E EPS, reduced from the prior 8x multiple.

  Weaknesses

  A lower target P/E multiple reflects uncertainty over the pace of valuation normalization and the need for clearer capital-allocation evidence.

  Comparison

  The report expects blended DRAM ASP to outperform the industry average in 3Q26E and notes a 46% pullback from the June peak versus 30% for KOSPI and 33% for memory peers.

  Risks

  AI capex could slow; memory ASPs could weaken; Chinese advanced-node supply could rise; HBM4/4E production could encounter disruptions.

Impact & implications

J.P. Morgan argues that durable AI-related memory demand, higher-value server products and improved HBM economics can sustain SK hynix's earnings beyond a short-term pricing fluctuation. It also says that clearer shareholder returns and capital allocation are important for valuation normalization.

Risks

• An unexpected slowdown in AI capital-expenditure plans could weaken demand.
• Weaker B2C demand could slow memory ASPs and pressure DRAM prices and margins.
• An influx of advanced-node supply from Chinese competitors could affect industry conditions.
• HBM4 or HBM4E production disruptions could impair execution.
• End-demand and inventory uncertainty remains a downside risk.

What to watch

• The duration and customer composition of LTAs, including price-hike clauses and contract terms.
• 3Q26 DRAM ASP recovery, HBM4 contribution and 2H26 results versus consensus.
• Further details on HBF, V10 375-layer 4D NAND and the AI-centric NAND strategy.
• The official capital-allocation and shareholder-return update expected by year-end.
• A potential buyback announcement, which J.P. Morgan expects could occur within the next couple of months.
