SK hynix ADR priced at premium to domestic shares — but is it all good news?

SK hynix priced its American depositary receipts at roughly 3% above its domestic common shares, securing a premium in the US market. However, analysts caution that the development is not an unqualified positive for investors holding the company's shares on the Korean exchange. While a sustained ADR premium could lift the domestic share price, a shift in investment demand from domestic common shares to ADRs could weigh on supply-demand dynamics at home.

SK hynix said Friday (Korean Standard Time) through its English-language website that it had set the IPO price for 177.9 million ADR shares at $149 per share. To support the offering, the company issued 17.79 million new shares — about 2.5% of its total outstanding shares. Each ADR represents one-tenth of one SK hynix common share.

SK hynix common shares closed at 2.186 million won on the domestic market on Thursday. Applying the won-dollar exchange rate of 1,509.9 won, the ADR offering price came in about 2.9% above the domestic closing price equivalent. SK hynix said the offering was "the only one in this IPO to achieve premium pricing."

SK hynix will raise $26.51 billion through the offering, surpassing the $25 billion raised by China's Alibaba during its New York Stock Exchange listing in 2014 to set a record for the largest US IPO by a foreign company. Including US companies, it ranks as the second-largest IPO in history, behind SpaceX.

The premium confirmed at the offering stage does not automatically translate into good news for domestic SK hynix investors. While a high ADR price in the US market could pull domestic shares higher, a migration of investment demand from domestic common shares to ADRs could strain the local supply-demand balance. The dilution effect from issuing new shares equivalent to 2.5% of total outstanding stock is another variable investors will need to weigh.

UBS had earlier recommended a strategy of buying SK hynix ADRs while selling the domestic common shares. According to Bloomberg, the Swiss bank judged that ADRs were likely to trade at a premium to domestic shares, citing greater accessibility for US investors and potential restrictions on converting Korean common shares into ADRs. The final offering price coming in 2.9% above the domestic equivalent confirmed the premium scenario UBS had outlined.

However, the offering-stage premium alone does not guarantee that ADRs will continue to trade above domestic shares after listing. The price gap could shift depending on exchange rates, supply-demand conditions in both markets and investor sentiment.

Investor demand proved stronger than expected. The offering drew orders exceeding seven times the amount on offer, according to Bloomberg and other reports. Long-term global investment funds, technology-focused funds, sovereign wealth funds and Asia-focused global investors were among those that participated. The strong turnout was seen as confirmation of positive global sentiment toward SK hynix, underpinned by expanding AI server investment and the company's competitiveness in the HBM market.

Market participants said the more meaningful signal was the strength of demand rather than the ADR listing itself. "The ADR listing was already known to the market, but what mattered was how much actual demand would materialize," an industry official said. "Orders exceeding seven times the offering size means global institutional investors still have a positive view of the memory chip cycle." The official added that the offering price being set above the domestic common share equivalent confirmed the investment sentiment in the US market.

SK hynix plans to use the full proceeds from the Nasdaq listing for three purposes: construction of the first fabrication plant at the Yongin semiconductor cluster, construction of the Cheongju P&T7 advanced packaging fab along with equipment and concessions, and acquisition of machinery including EUV scanners and facility investment.

SK hynix ADRs began conditional when-issued trading Friday under the ticker "SKHYV." Regular trading under the ticker "SKHY" will begin Monday, and the offering process is scheduled to close Tuesday. Bank of America, Citigroup, Goldman Sachs and JPMorgan are serving as joint bookrunners.
