SK Hynix is standing at the center of the U.S. capital market. On the 10th local time, the company held an opening bell ceremony to mark the listing of its American Depositary Receipts (ADRs) at Nasdaq MarketSite in Times Square, New York, and officially began trading. The event was attended by SK Group Chairman Chey Tae-won, Vice Chairman Chey Jae-won, and SK Hynix CEO Kwak Noh-jung, among other top executives.
The first-day performance was dazzling. The ADRs, which started at an offering price of $149, opened at $170 and rose as high as $177 during trading before closing at $168.49, up 13.08% from the offering price. The company raised $26.5 billion in the offering, equivalent to about 40 trillion won. That surpasses Alibaba’s $25 billion raised in 2014 and marks the largest U.S. listing ever by a foreign company.
ADR is a certificate issued so that foreign-company shares can be traded on U.S. exchanges after a depositary institution holds the underlying stock. It allows U.S. investors to buy SK Hynix with dollars, without currency exchange or a Korean securities account. Ten ADRs issued this time correspond to one common share in Korea, and the underlying 17.79 million newly issued shares amount to about 2.5% of the company’s existing listed shares.
Demand for the offering reportedly exceeded the allocation by more than seven times. The ADR began trading under the temporary ticker “SKHYV,” and the official ticker “SKHY” will be applied starting on the 13th. The offering proceeds will be paid in on the 14th, and the new shares are expected to be additionally listed on the domestic stock market around the 29th. In his commemorative remarks, CEO Kwak said, “We will prove our technological leadership and be there wherever AI exists.”
The essence of this listing goes beyond raising capital. The funds secured will be used for construction of the first fab at the Yongin semiconductor cluster, building an advanced packaging plant in Cheongju, and introducing extreme ultraviolet (EUV) lithography equipment. The key point is that, in a phase where AI memory demand is outpacing supply, the company found financing for expansion not in Korea but in the U.S. market.
Behind this lies a structural problem of valuation gaps. Even while leading the high-bandwidth memory (HBM) market, SK Hynix’s price-to-book ratio has remained far below that of U.S. rival Micron. In effect, the company chose to bypass the reality that its market value changes depending on where it is listed despite doing the same business.
The timing was also strategic. Based on the 자료 the company submitted to the U.S. Securities and Exchange Commission, its HBM market share reaches 56.4%. During pre-listing roadshows in the U.S., Europe, and Asia, institutional investors reportedly showed strong interest in the company’s technological edge and growth potential as a leader in the AI memory market. Industry observers also say that, considering the time needed to build new production facilities, memory supply shortages could continue for years.
The market’s response on the first day supported that logic. Converting the ADR closing price into Korean won puts the value at around 2.53 million won per common share. That is about 16% higher than the previous day’s domestic closing price of 2.18 million won. In other words, U.S. investors valued the same company more highly.
In the securities industry, more weight is being placed on the possibility of a revaluation effect. If inclusion in the Nasdaq 100 Index and the Philadelphia Semiconductor Index becomes a reality, passive fund inflows would follow, and the strength of the ADR could stimulate the domestic share price. There is also broad agreement that dilution concerns are limited because the new share issuance amounts to only about 2.5% of the existing shares.
As for the price gap, some point to precedent and see the premium as sustainable. In the securities industry, TSMC’s U.S. ADR has consistently traded at a higher price than its Taiwan-listed common shares, and the view is that additional U.S. demand and limited arbitrage could support the premium.
The counterarguments are no less strong. Among retail investors, dissatisfaction over dilution from the new share issuance has continued. There is also speculation that index inclusion will be difficult within this year, since eligibility for review comes only after a certain period following listing. Whether the 16% price gap between the ADR and the common shares will be maintained is also uncertain. It may narrow depending on future earnings, memory prices, exchange rates, and investor sentiment toward AI in the U.S. market.
Some also view this listing as a test of the sustainability of the memory supercycle. With large-cap stocks swinging amid fears of a semiconductor peak-out, ADR demand is being interpreted as a real-time vote on the industry outlook.
This listing signals the opening of a “dual-listing era” for major Korean stocks. The fact that companies are moving toward markets with the liquidity and valuation needed to support growth investment has now been proven by the figure of 40 trillion won. For Korea’s capital market, that is a painful reality.
The timing is awkward. The domestic market has recently experienced volatile swings between sharp drops and rebounds amid semiconductor peak-out concerns and Middle East risks. In such a climate, part of the price discovery function for a flagship stock has shifted to the U.S. market. There is both hope that a successful listing could revive dampened investor sentiment and concern that it marks the beginning of a shift in the center of liquidity.
Now that a successful case has been confirmed, there is a strong possibility of followers. Battery and biotech companies that require massive capital investment will have an incentive to consider the same route. If this trend takes hold, the domestic market risks losing pricing power to the United States and being pushed into a satellite-market role.
On the other hand, there is room for opportunity. If the ADR premium drives a revaluation of the common shares, it could act as a catalyst for reducing the Korea discount. The key question is whether the gap will narrow through a rise in the common shares or a fall in the ADR.
The first priority is to restore the domestic market’s fundraising function. The Financial Services Commission and the Korea Exchange must bring the speed and cost competitiveness of large-scale rights offerings and listing systems up to U.S. levels. An approach that tries only to keep capital in Korea without fixing the roots of the valuation gap—corporate governance and shareholder-return practices—will not work. If the perception takes hold that tens of trillions of won cannot be raised domestically, capital outflow will repeat.
Managing the price gap is also necessary. Arbitrage between the ADR and the common shares must function smoothly for the two markets to converge. Reducing trading friction such as foreign investor registration and foreign-exchange conversion procedures is the responsibility of the Ministry of Economy and Finance and the financial authorities.
Improving market infrastructure falls to the Korea Exchange and the Korea Securities Depository. If conversion and settlement between ADRs and underlying shares take several days, the gap will turn into a speculative playground. Only with shorter conversion times, transparent fees, and expanded English-language disclosure for major stocks can the two markets be linked to a single price.
Without expanding the demand base, any regulatory improvement will be only half a solution. The root cause of Korea’s inability to absorb 40 trillion won lies in the absence of long-term capital. Pension funds and other institutional investors should reassess the trend of reducing domestic equity allocations, and the National Assembly should enact legislation that encourages long-term holding, such as reforms to dividend income taxation, to lengthen the staying power of private capital.
Companies also have duties to fulfill. SK Hynix is reportedly planning to establish a concrete shareholder-return policy within the year. It must answer domestic shareholders who have borne the dilution from the new share issuance with dividends and share buybacks. Proving that the dual listing is not a structure built on the sacrifice of domestic shareholders is the starting point of a revaluation.
