SK Hynix filed a Form F-1 registration statement with the U.S. SEC and is targeting approximately $28 billion through an ADR listing on Nasdaq, with pricing expected on Friday, July 10, 2026, according to Reuters and Bloomberg.

The structure is a primary offering of 17.79 million new shares, represented as American Depositary Receipts — each ADR tracking an underlying position in the Korean won-denominated ordinary shares already trading on the Korea Exchange. The F-1 filed with the SEC discloses that the board of directors took formal action related to the offering on June 24, 2026. EX-5.1, the legal opinion attached to the filing, is addressed to SK Hynix's registered headquarters in Icheon-si, Gyeonggi-do.

If the deal prices at or near the $28 billion target, it would rank as the largest-ever U.S. listing by a foreign company, per Bloomberg. That figure exceeds prior foreign mega-listings — including Alibaba's 2014 NYSE debut — and reflects both the scale of SK Hynix's existing market capitalisation and the premium that equity markets have been attaching to HBM-exposed names.

The strategic rationale is straightforward. SK Hynix is the dominant supplier of High Bandwidth Memory — the stacked DRAM architecture that sits inside Nvidia's H100, H200, and Blackwell GPUs — and demand for that product has consistently outpaced supply since generative AI workloads began scaling in earnest. A Nasdaq listing deepens the company's access to U.S. institutional capital, which is disproportionately allocated to the AI infrastructure theme, and increases secondary market liquidity for index funds and active managers who face KRX operational friction. It also raises the company's profile with a U.S. customer and investor base that already has significant economic exposure to SK Hynix's output but limited direct equity access.

Worth noting on the mechanics: this is a primary issuance of new shares, not a secondary sell-down by existing holders. That means the $28 billion flows to the company's balance sheet rather than to SK Telecom or other incumbent shareholders. At that scale, the proceeds could meaningfully accelerate capacity expansion — HBM manufacturing is capex-intensive, requiring extreme ultraviolet lithography and through-silicon via stacking at volumes that few fabs globally can sustain.

The ADR route rather than a full U.S. incorporation or direct listing is the conventional path for established foreign issuers, and it preserves the primary KRX listing while creating a Nasdaq-listed instrument that settles in dollars, carries dollar-denominated dividends after conversion, and sits comfortably inside U.S. custody infrastructure. Pricing will set the initial ADR-to-ordinary-share ratio; that ratio, once fixed, determines the dollar price per ADR and the implied market cap at which U.S. investors are buying in.

The deal's sizing deserves sober scrutiny. Twenty-eight billion dollars of new equity is a material supply event even for deep U.S. markets. Bookrunners will need to absorb that demand across what is a compressed roadshow window — board action on June 24, F-1 on file, and a July 10 target listing date leaves roughly two weeks for institutional price discovery. The AI trade has attracted large allocations in 2025 and into 2026, but valuation discipline among long-only funds has tightened as rate expectations have stabilised. Whether the order book covers comfortably at the targeted size will be visible almost immediately given the listing timeline.

For practitioners tracking the KRX-listed ordinary shares, the ADR launch introduces a new arbitrage surface. Any sustained premium or discount between the ADR price (adjusted for the conversion ratio and FX) and the KRX close creates a tradeable spread — though withholding tax treatment on dividends and settlement timing differences mean the arb is not cost-free. Equity derivatives desks will be pricing SK Hynix options in USD for the first time, adding a new instrument to the HBM vol surface.

The July 10 date is four trading days away. The F-1 is live. The board has acted. What remains is execution.
