SK Square Investment Memo: When Does SK Hynix Cash Flow Become SK Square Cash?

Sat, 04 Jul 2026 21:40:00 +0900

Context This memo follows SK Hynix F-1/A and F-6, SK Hynix ADR price path, SK Hynix HBM market share 2026 and Micron FY3Q26 earnings.

TL;DR

SK Square should not be framed as the investment vehicle for the entire SK Group. SK Inc. is the official group holding company and portfolio coordinator. For public-market investors, SK Square is better defined as:

A listed AI and semiconductor capital allocator built on SK Hynix equity value, NAV discount compression and a call option on future SK Hynix special cash dividends.

The key variable is not SK Hynix net income by itself. Higher SK Hynix earnings lift SK Square’s equity-method income and NAV, but they do not automatically become SK Square cash. Cash reaches SK Square through SK Hynix dividends, stake sales, collateralization or SK Square’s own portfolio exits.

Current view: Wait / Conditional Buy. The buy case strengthens when SK Hynix free cash flow converts into cash dividends, SK Square receives that cash, and the company allocates it to buyback cancellation or Hynix-linked AI and semiconductor investments.

1. Correct Framing

SK Inc. is the official holding company for SK Group. It manages the broader group portfolio across energy, AI, semiconductors and other businesses. SK Square is different. It is an ICT and semiconductor investment company whose NAV is overwhelmingly driven by SK Hynix.

Item	SK Inc.	SK Square
Role	Group holding company and portfolio manager	ICT and semiconductor investment company
Main exposure	Broad SK Group portfolio	SK Hynix stake and AI/semi portfolio
Investor thesis	Group restructuring and holding-company discount	SK Hynix NAV, cash conversion, NAV discount compression
Main risk	Conglomerate complexity	Hynix dividends may not convert into SK Square cash

This distinction matters. Calling SK Square the group’s treasury overstates the case. The cleaner thesis is a listed AI and semiconductor allocator tied to SK Hynix cash-flow conversion.

2. NAV Is Mostly SK Hynix

SK Square’s official NAV page showed the following as of July 2, 2026.

Item	Value
Total NAV	KRW 324.7T
SK Hynix stake value	KRW 319.52T
Net cash	KRW 0.79T
NAV per share	KRW 2,460,288
SK Square share price	KRW 1,525,000
NAV discount	About 38.0%

The discount is calculated as 1 - 1,525,000 / 2,460,288. SK Square holds 146,124,531 SK Hynix shares, or 20.5%.

3. Earnings Are Not Cash

SK Hynix earnings affect SK Square through accounting income and NAV. But SK Square needs actual cash for buybacks, cancellations, dividends or new investments.

SK Hynix’s fixed dividend for 2025-2027 is KRW 1,500 per share. Applied to SK Square’s 146,124,531 shares, this equals KRW 219.2B, or about KRW 0.219T per year. That is about 28% of SK Square’s KRW 0.79T net cash. It is meaningful, but not enough to re-rate a holding company with KRW 319.52T of SK Hynix stake value.

The real option is special or additional cash dividends.

Total SK Hynix cash dividend	SK Square pre-tax receipt	Estimated after-tax receipt
KRW 1T	KRW 0.205T	About KRW 0.194T
KRW 5T	KRW 1.025T	About KRW 0.969T
KRW 10T	KRW 2.050T	About KRW 1.937T
KRW 20T	KRW 4.100T	About KRW 3.875T

The after-tax estimates use a simplified Korean dividend received deduction framework. A domestic parent owning at least 20% and less than 50% of a domestic subsidiary may exclude 80% of dividends from taxable income. Applying a 27.5% tax rate to the remaining 20% implies about 5.5% leakage.

4. NAV Discount Math

Holding NAV per share constant at KRW 2,460,288, the implied share price changes materially as the discount narrows.

NAV discount	Implied price
50%	KRW 1,230,144
45%	KRW 1,353,158
40%	KRW 1,476,173
38%	KRW 1,525,379
35%	KRW 1,599,187
30%	KRW 1,722,202
25%	KRW 1,845,216

SK Square has stated an objective of reducing its NAV discount to 30% or less by 2028. That is a target, not a guarantee. The market needs evidence: Hynix cash dividends, SK Square buyback cancellations, non-core exits and disciplined AI/semi investments.

5. Shareholder Return And Capital Allocation

SK Square’s 2023-2025 shareholder-return policy uses at least 30% of recurring dividend income and part of meaningful investment gains for shareholder returns. Methods include buybacks, cancellations and cash dividends.

At a high NAV discount, buyback cancellation is powerful. If a company trades at a 38% NAV discount, buying back stock is economically similar to buying KRW 1 of NAV for KRW 0.62. That means low-return investments are hard to justify unless they have clear Hynix-linked strategic value.

6. U.S. Cash Is Not Automatically Trapped Cash

SK Hynix’s U.S. customer revenue is large. Reported 2025 U.S. customer revenue was KRW 66.885T, about 69% of total revenue. SK hynix America reportedly generated KRW 58.693T of sales and KRW 235.9B of net income, implying a net margin of about 0.40%.

That low margin suggests the U.S. sales entity may be a limited-margin distributor rather than the place where most economic profit accumulates. Cash can return to the Korean parent through product payment, transfer-pricing settlement, intercompany payments, dividends, royalties or other structures.

The important question for SK Square is not whether U.S. revenue is large. It is whether SK Hynix parent-level free cash flow grows and becomes cash dividends.

7. SKHY ADR Read-Through

SK Hynix is pursuing a U.S. ADR listing. Reuters reported that the company may raise up to $29.4B, with proceeds for Korean semiconductor factories and EUV equipment.

For SK Square, the ADR is positive for investor access and potentially for SK Hynix’s valuation. But it is not a direct cash-in event for SK Square. The proceeds go to SK Hynix. SK Square benefits through NAV, valuation and future dividends, while also facing potential ownership dilution from new share issuance.

8. Investment Ideas

Idea	Thesis	Required proof
Hynix FCF-to-cash option	Hynix earnings matter only when they become SK Square cash	FCF after capex and meaningful cash dividends
Listed AI/semi allocator	SK Square becomes a disciplined Hynix-linked investment platform	Investments tied to Hynix ecosystem, not generic AI hype
NAV discount compression	Discount narrows from about 38% toward 30%	Buyback cancellation, non-core exits, capital discipline
U.S. trapped-cash misunderstanding	Large U.S. revenue does not mean large trapped U.S. profit	Parent-level FCF and tax-efficient cash flow

9. Practical View

Security	View	Reason
SK Square	Wait / Conditional Buy	NAV discount is meaningful, but cash conversion and capital allocation need confirmation
SK Hynix	Watchlist	Source of cash flow and NAV
SK Inc.	Separate thesis	Official holding company, but less direct Hynix cash-flow exposure

Entry conditions:

Condition	What to see
Wider discount	Updated NAV discount at or above 45% while the Hynix HBM thesis remains intact
Cash conversion	Hynix special cash dividend or early additional shareholder return, followed by SK Square buyback cancellation or Hynix-synergy investment
Allocator trust	Non-core exits, AI/semi discipline, no group-support capital allocation

Invalidation:

Risk	Meaning
Hynix earnings are strong but FCF is absorbed by capex and working capital	No SK Square cash conversion
Hynix returns capital mainly through buybacks rather than cash dividends	Limited SK Square cash inflow
SK Square uses Hynix dividends for group support	Holding-company discount widens
Low-return investments take priority over buyback cancellation	Capital allocation trust declines
ADR dilution outweighs lower cost of capital	SK Square’s Hynix stake economics weaken

Final View

SK Square is not cash-rich today. Official net cash is KRW 0.79T. But it owns KRW 319.52T of SK Hynix stake value. If SK Hynix AI-memory earnings convert into free cash flow and cash dividends, SK Square can receive trillions of won over time.

The strongest thesis is not “SK Hynix is good, therefore SK Square is good.” It is more specific: SK Hynix FCF must become cash dividends, SK Square must allocate that cash to buyback cancellation and Hynix-linked investments, and the NAV discount must compress structurally.

How SK Hynix's ADR Could Change 000660 Price Discovery And Leveraged ETF Flows

Sat, 04 Jul 2026 07:18:00 +0900

Context This is a follow-up to SK Hynix F-1/A and F-6: how the SKHY ADR packages HBM capex. The previous note focused on the filing mechanics. This note focuses on price transmission, ADR-common-share arbitrage and single-stock leveraged ETF flows.

TL;DR

The SK Hynix ADR is structurally positive over the medium term, but it is not a near-term volatility dampener. It widens U.S. investor access and may allow SK Hynix to be compared more directly with U.S.-listed AI memory peers. But right after listing, the key variables are the offer discount, the first week of ADR trading quality, the ADR premium or discount to the KRX common share and the impact on Korea’s single-stock leveraged ETF plumbing.

Question	View
Is the ADR positive for 000660?	Medium-term yes, because investor access and peer framing improve.
Is it an immediate buy signal?	No. Pricing, discount and initial premium or discount must be checked first.
What is the key mechanism?	ADR-common-share arbitrage. If the ADR trades rich to implied parity, it can create KRX common-share buying pressure. If it trades cheap, it can pressure the common share.
Can the ADR absorb Korea’s 2x ETF overheating?	Not in the short run. The bottleneck is KRX close rebalancing, not U.S. access.
Current stance	Watch the common share and the ADR. Avoid leveraged wrappers if the goal is HBM exposure.

1. What Is Confirmed

SK Hynix has filed an F-1/A for a planned Nasdaq Global Select Market ADS listing under SKHY.¹ The F-6 filed by Citibank states that each ADS represents the right to receive one-tenth of one common share.² Press reports indicate a maximum new-share issuance of 17.79 million common shares, around 2.5% of existing common shares.³

The final ADS count, offer price and net proceeds remain blank in the F-1/A. That matters. The investment signal is not merely that an ADR is coming. The signal will be in the final price, the discount to the Korean common share and the first few days of trading.

2. Access Premium

The first effect is access. U.S. investors can buy SK Hynix exposure in dollars, during U.S. hours, without using a Korea trading account or indirect ETF exposure. That can shift the comparison set from “Korean memory stock” to “U.S.-tradable AI memory and HBM supplier.”

This is positive, but not new information for the stock. Much of the obvious ADR rerating argument has already been anticipated. The remaining alpha is whether U.S. investors pay at or above implied KRX parity after the ADR starts trading.

3. New Shares And Dilution

The ADR is linked to new share issuance, not merely a secondary sale by existing holders. The headline maximum is about 2.5% of existing shares. That is dilution in ownership terms, but not necessarily large economic dilution if the offer price is close to market and proceeds are invested into HBM, eSSD, advanced packaging and EUV-related capacity.

Scenario	Read-through
Small discount and strong order book	U.S. investors validate the common-share price. Positive for 000660.
Large discount and weak demand	U.S. market rejects the prevailing valuation. Negative for 000660.
ADR premium after listing	U.S. demand can support KRX common shares.
Persistent ADR discount	U.S. trading becomes a new downside anchor.

With one ADS representing 0.1 common share, parity is simple:

Calculation	Formula
Implied ADR price from KRX common share	`KRX common price × 0.1 ÷ USD/KRW`
Implied common-share price from ADR	`ADR price × USD/KRW × 10`

If the ADR trades above implied parity, arbitrageurs may buy KRX common shares and sell or create ADR exposure. That creates common-share buying pressure. If the ADR trades below parity, arbitrageurs may buy ADRs and sell common-share exposure, pressuring the KRX line.

Therefore the first week is not about the absolute ADR move. It is about the premium or discount versus the Korean common share, after conversion costs, FX, settlement and stock-borrow constraints.

5. U.S. Price Discovery

The ADR extends SK Hynix price discovery into U.S. trading hours. This helps incorporate Nvidia, Micron, SOX, rates and AI capex news faster. But it also imports U.S. overnight gap risk into the Korean open. The ADR is a price-discovery channel, not automatically a volatility cushion.

6. Leveraged ETF Plumbing

The ADR does not directly remove Korea’s single-stock 2x ETF rebalancing pressure. Korean 2x ETFs must maintain daily target exposure through common shares, futures, swaps and liquidity provider hedging around the KRX close. The Korean Financial Services Commission described the daily 2x structure when single-stock leveraged products were introduced.⁴ The Korea Capital Market Institute estimated SK Hynix leveraged ETF AUM at KRW 9.15tn as of June 19 and highlighted how daily rebalancing can amplify volatility.⁵

The core issue is mechanical. When SK Hynix rises, 2x ETF exposure may need to increase. When it falls, exposure may need to decrease. That creates a short-gamma-like flow. An ADR only offsets this if U.S. long-only ADR demand is large enough to replace the domestic leveraged flow. That is possible later, but not proven now.

7. What To Watch

Watch item	Why it matters
Final offer price and discount	Tests U.S. demand quality.
First 3 to 5 days of ADR premium or discount	Determines whether U.S. trading supports or pressures 000660.
ADR trading value	Shows whether SKHY can become a real price-discovery line.
Korean leveraged ETF AUM	Shows whether the domestic short-gamma pipe is cooling.
HBM ASP, shipment and capex commentary	Keeps the ADR story grounded in earnings.

Final View

SKHY is a major capital-market event for SK Hynix. It can broaden the investor base and reframe the company as a U.S.-tradable AI memory supplier. But the ADR does not immediately solve the domestic leveraged ETF problem. The near-term stance is watchlist for the common share and ADR, and avoidance of leveraged wrappers if the goal is clean HBM exposure.

SK Hynix F-1/A and F-6: What The SKHY ADR Says About HBM Capex

Sat, 04 Jul 2026 05:20:00 +0900

Context This is a follow-up to SK Hynix: the HBM leader in the AI revolution, SK Hynix HBM market share 2026, SK Hynix vs Micron and Micron FY3Q26 earnings.

TL;DR

SK Hynix’s SEC filings are not just an ADR wrapper. The sequence from the June 24 F-1, the June 30 F-1/A and the July 1 F-6 shows the company packaging its HBM leadership, eSSD, Custom HBM and Korea capex roadmap for U.S. AI-memory investors.

Item	Confirmed	Investor interpretation
F-1/A	Filed June 30, 2026. Nasdaq Global Select Market application under `SKHY`. ADS count, price and net proceeds are still blank.	Not final terms yet. A further amendment or final prospectus is required.
F-6	Filed July 1, 2026. Citibank is depositary. Each ADS represents one-tenth of one common share.	This fills the key ADR ratio that remained blank in the F-1/A cover.
New-share ceiling	Board authorization for up to 17,790,000 new common shares, 2.50% of 712,702,365 existing shares.	Maximum dilution is limited, but actual issuance remains unknown.

The most important caveat: the F-6 registration of 1,780,000,000 ADSs is not the offering size. Form F-6 registers the ADR facility and the related depositary-fee calculation. The actual equity offering size depends on the final ADS count and offering price in the F-1/A or final prospectus.

The stock read-through is Watchlist. This is an access and ownership-base event, not a fresh discovery of the HBM thesis. The alpha question is whether U.S. long-only and AI-memory investors use SKHY as a cleaner vehicle for SK Hynix exposure.

1. Why The June 24 F-1 Is Not Enough

Filing date	Form	Document	What changed
2026-06-24	F-1	Registration No. 333-296987	Initial ADS offering and Nasdaq listing preparation; key offering terms blank
2026-06-30	F-1/A	Amendment No. 1	Offering structure, new-share ceiling, use of proceeds and capex tables updated; ADS count and price still blank
2026-07-01	F-6	Registration No. 333-297185	Citibank depositary and one ADS = one-tenth common share

The company is SK hynix Inc. Its common shares trade on KOSPI under 000660. The ADSs are expected to trade on the Nasdaq Global Select Market under SKHY, subject to effectiveness and listing approval.

2. Offering Mechanics

Item	Latest status
Issuer	SK hynix Inc.
ADS ticker	`SKHY`, Nasdaq Global Select Market application
Depositary	Citibank, N.A.
Global coordinators	BofA Securities, Citigroup, Goldman Sachs, J.P. Morgan
ADS ratio	F-6: 1 ADS = 0.1 common share
ADS count	Blank in F-1/A
Offering price	Blank in F-1/A
Net proceeds	Blank in F-1/A
Lock-up	90-day lock-up may apply to the company and certain affiliates, subject to exceptions

The board authorized up to 17,790,000 new common shares. Against 712,702,365 existing shares, that is 2.50%. If fully issued, new shares would be about 2.44% of the post-issue share count. This is a ceiling, not the actual offering size.

3. F-6 ADS Registration Is Not Equity Proceeds

The F-6 registers 1,780,000,000 ADSs, each representing one-tenth of one common share. It also uses a fee calculation of $5.00 per 100 ADSs, giving a proposed maximum aggregate fee-basis amount of $89,000,000 and a registration fee of $12,290.90.

That fee basis is not the gross equity offering. Investors should not read 1.78 billion ADSs as the number of ADSs that will be sold in this offering. The real offering size remains blocked until the final ADS count and offer price are filed.

4. Use Of Proceeds: Yongin, P&T7 And EUV

The F-1/A frames proceeds around general corporate purposes, including capital expenditures. The filing specifically discusses KRW 45.5 trillion of Korea production-facility capex and approximately KRW 11.9 trillion of EUV scanner cost, with EUV delivery expected by December 2027.

Project	Target completion of planned investments	Total expected cost	Invested by May 31, 2026	Additional planned investment
Yongin Fab 1	End of 2030	KRW 31.0T	KRW 4.4T	KRW 26.6T
Cheongju P&T7	End of 2030	KRW 19.0T	KRW 0.1T	KRW 18.9T
Total	End of 2030	KRW 50.0T	KRW 4.5T	KRW 45.5T

Project	2026	2027	2028	2029	2030	Total
Yongin Fab 1	KRW 7.4T	KRW 10.1T	KRW 6.6T	KRW 2.5T	KRW 0.0T	KRW 26.6T
Cheongju P&T7	KRW 0.5T	KRW 2.1T	KRW 2.7T	KRW 5.8T	KRW 7.8T	KRW 18.9T
Total	KRW 7.9T	KRW 12.2T	KRW 9.3T	KRW 8.3T	KRW 7.8T	KRW 45.5T

The business section and capex table use different milestones. The business section points to the first Yongin cleanroom opening in 1Q27 and P&T7 construction completion by end-2027. The capex table targets completion of planned investments by end-2030. That is not necessarily a contradiction; it separates phase-opening from full investment completion and equipment installation.

5. The Narrative: HBM, Custom HBM And eSSD

The F-1/A does not present SK Hynix as a plain DRAM-cycle company. It emphasizes HBM, server DRAM and eSSD as structural AI-infrastructure products.

Market	IDC-based position in 1Q26
DRAM including HBM	No. 2 by revenue, 29.1% share
HBM	No. 1 by revenue, 56.4% share
NAND flash	No. 2 by revenue, 18.5% share

Custom HBM is especially important. The filing defines it as HBM that integrates certain GPU or ASIC functions into the HBM base die according to customer configuration. That shifts the story from memory pricing alone toward memory becoming part of the accelerator design stack.

6. Recent Financials

Metric	1Q25	1Q26	Change
Revenue	KRW 17.639T	KRW 52.576T	+198.1%
Profit for the period	KRW 8.108T	KRW 40.346T	~5.0x
Total assets	KRW 176.108T at 2025-end	KRW 222.829T at Mar. 31, 2026	+26.5%
Total equity	KRW 120.667T at 2025-end	KRW 164.380T at Mar. 31, 2026	+36.2%

Product	1Q26 revenue	Share
DRAM	KRW 40.659T	77.3%
NAND	KRW 11.574T	22.0%
Other	KRW 0.343T	0.7%

The U.S. accounted for KRW 33.999T, or 64.7% of 1Q26 revenue. That makes the ADR event strategically coherent: the investor access point is moving closer to the customer-revenue geography.

7. Shareholders, Dividends And Governance

Shareholder	Shares	Ownership
SK Square	146,100,000	20.50%
National Pension Service	57,439,774	8.06%
BlackRock	36,407,157	5.11%
Capital Research and Management	25,149,374	3.53%
Others	445,979,195	62.58%
Treasury shares	1,626,865	0.23%

The filing says the maximum offering size reflects the Korean Monopoly Regulation and Fair Trade Act requirement that SK Square maintain at least 20% ownership.

The 2025-2027 base dividend policy is KRW 1,500 per share per year, paid quarterly at KRW 375. The 2025 total dividend was KRW 3,000 per share after additional annual distribution. This ADR story is not a dividend story; it is a capex and AI-memory access story.

8. Risks

The main risk factors remain memory cyclicality, HBM manufacturing complexity, AI infrastructure slowdown, customer concentration, U.S.-China restrictions, raw materials, water, power, equipment, foreign-exchange volatility and ADS-specific rights. ADS holders exercise voting and dividend rights through the depositary and can face conversion, cancellation or redeposit limitations.

9. Investment View

SKHY can make SK Hynix easier to own for U.S. AI-memory investors. It can also make the comparison with Micron’s U.S.-listed AI-memory premium more direct.

But this is not yet an immediate buy signal. The final ADS count, offering price, net proceeds, effective date and first trading date remain unavailable. The event belongs on the watchlist until those terms are filed.
