# What catalysts could drive upside/downside for SK Hynix in the next 12–18 months?

# SK Hynix (000660 KS) — Catalyst Map for Next 12–18 Months

**Current setup**: HC O-PF on CLSA's list with a target price of **₩350,000** (raised from ₩290,000 on 25 Jun 2025, ~+22% upside at the time of publication) [1][9]. SK Hynix delivered record FY2026 Q1 revenue of **KRW 52.58T (+60% QoQ / +198% YoY)** and operating profit of **KRW 37.61T (OPM 72%)** — i.e. the latest print already validates the bullish setup that the catalyst list below either extends or threatens [13]. Net-debt-to-equity flipped to **-21%** (net cash KRW 35T+), giving the balance sheet flexibility to fund the next-cycle investment cycle and shareholder returns simultaneously [13].

## I. Upside Catalysts (Probability-Weighted High → Low)

### 1. HBM4 ramp & ASP uplift (HIGH conviction — biggest single P&L lever)
- HBM4 mass production begins **Sep/Oct 2025 (4Q25)**, with crossover vs. HBM3E 12-Hi in 2H26; HBM4 is expected to become the **mainstream HBM product for Hynix in 2H26** [4][5].
- Pricing is still under negotiation but a **~30% ASP premium over HBM3E 12-Hi** is likely given higher production cost + substantial performance improvement [5].
- HBM revenue as % of DRAM has gone **5% (2022) → 14% (2023) → 29% (2024) → 45% (2025CL) → 50% (2026CL)** [11]. CLSA expects HBM share to **stabilise at 55–60% in 2027–28** with HBM shipments rising **40% in 2026 after 95% in 2025** — implying a structural rerating story [10].
- SK Hynix's own FY2026 Q1 deck confirms: HBM4 ramp on schedule, working closely with customers from early stages [15], and DRAM revenue mix from Graphics/HBM was 50–53% in '25 and remains ~44% in '26 Q1 even as Server DRAM grew rapidly.

### 2. Customer diversification beyond NVIDIA (HIGH)
- ~**70% of Hynix's HBM supply currently goes to NVIDIA** [1]. 2026 NVIDIA HBM negotiations were expected to finalise by 1H25; remaining capacity is being negotiated with **ASIC customers within 2H25** [2].
- Strong interest from new ASIC customers for inferencing chips could **drive shipment upside in 2026** and unlock further multiple expansion — CLSA explicitly flags that "if Hynix shows a meaningful diversification in its HBM customer base… we believe this multiple could expand further" beyond the 1.7x PB target [10].
- Hard tangible signal in FY2026 Q1 deck: **mass production of 1cnm 192GB SOCAMM2 optimized for NVIDIA's Vera Rubin platform** — i.e. Hynix has locked in next-gen GPU socket position [15].

### 3. Conventional DRAM tightness drives ASP resilience in 2H25-2026 (HIGH)
- Wafer reallocation from conventional DRAM to HBM/premium products is **tightening conventional DRAM supply**; combined with declining customer inventory and geopolitically-driven inventory rebuild, the **favourable memory pricing backdrop is expected to continue into 2H25** [1].
- Cloud hyperscaler capex projected **+35% in 2025 and +20% in 2026** — directly funds AI memory demand [1].
- Legacy DDR4 up **30% QoQ in 2Q25** already boosted operating profit [6]; SK Hynix's own outlook (Q1 FY2026 slides) flags that **"as memory becomes increasingly critical in AI computing, demand for high-performance memory is surging while supply remains constrained, expect favorable pricing environment to continue for the time being"** [14].

### 4. Korean sovereign AI investment (MEDIUM-HIGH)
- Korean government plan to invest **₩100tn in sovereign AI and AI data centres** over coming years positions SK Hynix as a primary direct beneficiary [2].

### 5. Capex / Yongin Cluster / M15X ramp positioning (MEDIUM-HIGH)
- FY2026 Q1 deck: **"This year's CapEx expected to increase significantly compared with last year… Majority allocated to infrastructure preparation centered on Yongin Cluster and ramp up of M15X"** — pre-emptive capacity build that locks in HBM4/HBM4E supply through 2027 [17].
- Net cash >KRW 100T target supports **dividends + share buybacks & cancellations** being actively reviewed for implementation within the year — explicit shareholder return catalyst [17].

### 6. NAND demand recovery (MEDIUM — wildcard)
- CLSA explicitly lists "faster-than-expected NAND demand recovery" as a stock catalyst [3][7].
- Micron commentary (read across): optimistic eSSD demand recovery in 2H25 after customer inventory digestion in 1H25 — would directly help Hynix/Solidigm.

### 7. China-fab export-control fallout (paradoxical positive)
- US Commerce considering revoking memory equipment waivers for Korean fabs in China; in the short term, "**if any production disruptions were to happen it might lead to even tighter supply of memory, especially DRAM**" — a near-term ASP positive even though it is a long-term structural negative [8].

### 8. Valuation rerating (MEDIUM)
- Target derived from **1.7x PB** (vs. +2 std dev above 10-year average of 1.2x). Historical maxima were 2.7x (2012), 1.9x (2014), 2.0x (2024) — i.e. **upside multiple headroom exists** if HBM dominance + customer diversification narrative compounds [10].

## II. Downside Risks (Severity-Ranked)

### 1. China substitution + supply expansion (HIGH structural)
- "**Rapid production expansion at Chinese chipmakers** could also pose a threat to Hynix" — CXMT/YMTC capacity additions are the principal asymmetric long-term threat to legacy DRAM/NAND ASPs [7].

### 2. AI capex normalisation / demand pull-in unwind (HIGH probability-weighted)
- Hyperscaler capex growth decelerating from +35% (2025) to +20% (2026) [1]. Any sharper deceleration — or evidence of AI training capex digestion — directly hits the HBM volume thesis.
- Tariff-related demand pull-in risk explicitly flagged: **"customers may have tariff-related demand pull-in"** ahead of 2H25 [10].

### 3. PC/Smartphone demand softness from memory price elasticity (MEDIUM)
- SK Hynix's own outlook explicitly acknowledges: **"Some signs of softening demand, including adjustments in set shipments and product portfolio changes, have emerged due to cost pressures from higher memory prices"** — server demand currently offsets this, but the buffer is thinning as DRAM ASP climbs further [16].

### 4. NAND inventory overhang (MEDIUM, partly priced)
- At end-1Q25 NAND inventory stood at **15 weeks** (vs. DRAM 7.5 weeks), reflecting sluggish HDD→eSSD transition. Hynix is constraining utilisation + capex; any further delay in eSSD ramp prolongs the NAND drag [6].

### 5. Trade war / geopolitics (MEDIUM)
- "Major risks include the **ongoing trade war, geopolitical tension between US and China and delayed demand recovery** in the IT and server market" [7].

### 6. China-fab production disruption (MEDIUM-HIGH long-term)
- If US revokes waivers, mid-to-long-term Korean suppliers must accelerate fab construction in Korea to reduce China production footprint — capex inflation + execution risk [8].

### 7. Samsung's HBM3E qualification at NVIDIA (DOWNSIDE for Hynix)
- CLSA flags potential **HBM3E approval from NVIDIA** as a Samsung-specific catalyst [Samsung context — chunk also in scope]. From Hynix's perspective, this is the single biggest market-share-loss risk because Hynix's 70%-NVIDIA concentration becomes a vulnerability the moment a second supplier qualifies at scale.

### 8. HBM4 execution / yield risk (LOW-MEDIUM)
- Production starting Sep/Oct '25 — any yield slippage or qualification delay during 4Q25-1H26 would compress the ASP premium and disturb the customer diversification timing.

### 9. Inventory correction risk (LOW currently, structural)
- "Ongoing inventory correction in the memory market" is enumerated explicitly as a risk; not the base case today, but historically the memory cycle's swing factor [7].

## III. Key Dates / Trigger Events to Watch (Next 12–18 Months)

| Window | Trigger | Direction |
|---|---|---|
| **3Q25** | Closure of 2H25 HBM contracts with ASIC customers (the remaining 30% of capacity) [2] | Upside if diversification announced |
| **Sep–Oct 2025** | HBM4 mass production begins [5] | Upside on volume + ASP confirmation |
| **2H25** | Resolution on US Commerce China-fab waivers [8] | Bidirectional — near-term supply tightness vs. long-term overhang |
| **4Q25 — 1H26** | NAND/eSSD demand recovery print [3] | Upside if recovery materialises |
| **2H26** | HBM4 becomes mainstream / HBM3E 12-Hi crossover [4][5] | Upside on ASP/mix |
| **Ongoing** | Samsung HBM3E NVIDIA qualification | Downside on share loss |
| **Ongoing** | Hyperscaler capex revision cycle (vs. +20% 2026 base case) [1] | Bidirectional |
| **Within '25/'26** | Shareholder return measures (dividends/buybacks/cancellations) [17] | Upside |

## IV. Bottom Line — Skew Assessment

The 12–18-month risk/reward remains **asymmetrically positive**, driven by (a) HBM4's locked-in ASP/volume tailwind into 2H26, (b) conventional DRAM tightness from wafer-mix shift, and (c) optionality on ASIC-customer diversification. The principal pinch points are concentration risk (NVIDIA = 70% HBM), Samsung's HBM3E qualification timing, and Chinese supply expansion — all of which become more material *after* the 18-month catalyst window, not within it. Within the catalyst horizon, CLSA's investment thesis stands: **DRAM/NAND demand rebound + HBM leadership through 2028 + DDR5 transition** [12], with valuation underpinned by 1.7x forward PB and clear path to higher multiples on customer diversification [10].
