1/ SK Hynix is going to go public on the US stock market, which many people have not yet understood. The first reaction may be: Hasn't Hynix already been launched in Korea? Why can we still go to the US stock market? Is this creating an additional company out of thin air? What is the difference between American stock Hynix and Korean stock Hynix? The core consists of two words: ADR。 2/ ADR， The full name is American Depositary Receipt. Simply put, it means: The company deposits its overseas equity in a custodian bank, which then issues a tradable "stock certificate" in the US market. So ADR is not another company. The Korean exchange has regular stocks. On the US stock market side, it is ADR. When you buy ADR, what you legally buy is depositary receipts, not ordinary shares directly registered in the Korean shareholder register. But behind it, it usually represents the economic interests of the same company. 3/ The key aspect of the Hynix this time is: It's not just about moving old stocks to the United States for trading. According to current information, it is more like going public through ADR financing. That is to say, the company will issue a portion of Korean common stock and package these new shares as ADRs to sell to American investors. This is not simply a matter of 'trading in a different place'. If it is only a conversion of old shares, the total share capital remains unchanged. But if it is an issuance of new shares, the total share capital will increase and the existing shareholders will be diluted to a certain extent. So looking at this matter, the focus is not on the three words' listing on the US stock market '. But rather: How much to send? What is the conversion ratio? What will the funds raised be used for? Is the dilution large or not? Will US funds reprice it? 4/ At present, it is important to mention a detail: 10 ADRs=1 Korean stock. So we cannot directly compare ADR prices with Korean stock prices. Some people think that the US stock market is cheap just by looking at its low price. Or when you see the high price of Korean stocks, you may think they are expensive. This is all wrong. You must first look at the conversion ratio, then look at the exchange rate, and finally see if there is a price difference between the two sides. In the long run, ADR and equity will not completely decouple. Because it represents the economic interests of the same company behind it. But there will be differences in the short term. Due to the different trading hours of US and Korean stocks, the exchange rate between the US dollar and the Korean won will fluctuate, and the sentiment of investors on both sides will also be different. 5/ Why did Hynix do this? I think the core is just one sentence: It wants to sell the HBM mainline directly to American investors. In the past, when American investors wanted to buy AI storage, the most convenient option was Micron. But the problem is that the true core players of HBM are not just Micron. Hynix has a strong presence on the HBM line, especially in the Nvidia supply chain, where it is an indispensable name. Previously, American investors wanted to buy Hynix directly, but the threshold was relatively high. Either buy from the Korean market. Either indirectly allocate through Korean ETFs or semiconductor ETFs. Now that ADR is available, US stock investors can trade directly in US dollars. The entrance has become simpler, making it easier for funds to come in. 6/ This matter is even more interesting when viewed in the present moment. Recently, AI hardware momentum trading has just receded, and storage and semiconductors have been hit hard. The market has shifted from "whoever is related to AI will rise" to "who can really turn AI demand into profit". At this time, Hynix's listing on the US stock market is equivalent to putting an HBM core target in front of US funds. On one hand, the valuation of AI hardware is too high, and funds are reducing risks. On the other hand, US funds can finally trade HBM core assets more directly. These two forces will exist simultaneously. So after it goes public, there is a high probability that the volatility will not be small. 7/ What I am more concerned about is not whether it will rise on the first day. But rather a few questions: Will HBM supply and demand continue to be tight? Has there been any change in Nvidia orders? Has cloud vendor CapEx continued to upgrade? Will the funds raised by Hynix continue to be directed towards advanced packaging, EUV, and HBM production capacity? Is the market willing to accept the dilution brought by this issuance? If the demand for AI continues to be strong, financing expansion may be understood as seizing the window period. If AI CapEx starts to slow down later, this financing may also be interpreted as a cyclical high point fundraising. This is the core disagreement. 8/ Hynix's listing on the US stock market is another new company that has emerged. It is trading Korean stocks in the US market through ADR. More importantly, it is not just a shell swap transaction, but a true financing listing. ADR is just a form of transaction. What really matters is the HBM demand, financing purpose, equity dilution, and AI hardware cycle behind it. Hynix's visit to the US stock market this time is essentially doing one thing: Deliver the world's hottest AI storage assets to the world's wealthiest capital markets.
