Key points
- Myoung Shin's board rejects its US unit's IPO
- Why Myoung Shin shareholders objected
- What Myoung Shin's vote means for the listing
- Why SK Hynix investors are watching Myoung Shin
Myoung Shin Industry (명신산업, 009900) has voted against taking its US car parts unit, Simwon America, public on Nasdaq. The October 20 board decision puts the listing in doubt. Myoung Shin's shares rose 17.8% the next day.
Korean outlets drew a parallel with SK Hynix, whose US unit Solidigm has reportedly picked banks for a Nasdaq IPO.
Myoung Shin said in its regulatory filing that it needs to reassess its shareholder protections and communication. Its own parent, MS Autotech (엠에스오토텍, 123040), voted against the listing the same day. The votes don't withdraw Simwon America's US registration by themselves.
Simwon America makes car body parts in Lathrop, California, and almost all its sales go to Tesla. Its S-1 registration statement, filed with the US Securities and Exchange Commission on October 9, sought a Nasdaq listing under the ticker SWA, with trading planned for November 25. Simwon America planned to sell 1.5 million new shares at $18 to $22 each, and earlier investors planned to sell 1 million more.
Why the ownership chain matters
MS Autotech owns 45.4% of Myoung Shin, which owns all of Simwon Tech (심원테크). Simwon Tech owns 89.7% of Simwon America. MS Autotech and Myoung Shin already trade in Korea, so listing Simwon America would make three of the four companies public. SK's chain above Solidigm is even longer.
In Korea, this is called a duplicate listing. Myoung Shin's shareholders already own part of Simwon America indirectly. They worry that a separate listing would lower the value investors put on the parent, and that new Simwon America shares would shrink their indirect stake.
How shareholders were consulted
Korea's duplicate-listing guidelines took effect in August and also cover overseas listings. They call on a parent's board to assess the effect on its shareholders, develop protections, and consult shareholders or seek their approval before deciding whether to support the listing.
Myoung Shin's filing says the guidelines require a shareholder vote only when the unit was created by splitting off part of the parent's business. Simwon America was set up as a new company in California in June 2016. So Myoung Shin held an online investor briefing on October 14 and surveyed shareholders from October 14 to 16 instead.
The filing says Myoung Shin will notify Simwon America of the board's decision. As of October 21, Simwon America hadn't filed to withdraw its S-1.
Critics questioned the IPO and Myoung Shin's offer
Simwon America's sales fell 13% to $323.9 million in the year to June 30, 2026, while its net income rose 50% to $16.9 million, the S-1 shows. The company had $39.4 million in cash at the end of June and expected $23.9 million from the new shares after costs. About half of the net IPO proceeds would go toward buying a company on the US East Coast and expanding into Mexico and Canada. About 10% would set up a research team, and 40% would be working capital.
Myoung Shin and MS Autotech have said they want Simwon America to raise money for its North American growth itself, so the parents don't have to invest, borrow, or guarantee loans for it. Market critics cited by Asia Economy (아시아경제) argued the IPO wasn't needed. In their view, Simwon America's cash was already larger than the expected proceeds, its bank credit lines were sufficient, and its operating cash flow was healthy.
Before the survey, Myoung Shin offered ordinary shareholders, not related parties, a special dividend of 7 billion won ($5.3M) in total over three years. The company also planned a regular dividend of 100 won ($0.08) a share for three years. Critics in the same report said that wasn't enough, since Myoung Shin already paid 100 won a share this year. MS Autotech's plan named no won amount.
The 1 million existing shares belonged to three investors that paid $9 million for their Simwon America shares in November 2025. At the $20 middle of the price range, those shares would bring in about $20 million before fees, by our calculations. That money would go to the investors, not to Simwon America.
Korean outlets see a lesson for SK Hynix
Hankyoreh (한겨레) called Myoung Shin's vote the first time a parent company's board has voted against a unit's listing since the rules took effect. The paper explained that a parent's board can't decide a unit's listing directly, but it can use its control over the unit to put the brakes on one.
SK Hynix's board hasn't said where it stands on a Solidigm listing. "It's a case that could serve as a warning to SK Hynix's board as well," a financial regulatory official told the paper.
Lee Nam-woo (이남우), chairman of the Korea Corporate Governance Forum (한국기업거버넌스포럼), praised the board. "Under the revised Commercial Act, the Myoung Shin board's resolution protected existing shareholders' interests and treated all shareholders fairly," he said. "It will be a precedent other companies can refer to when they pursue overseas listings."
"Myoung Shin is a textbook case that confirms an overseas duplicate listing still has to meet at least the principles of the Korea Exchange guidelines," he told iNews24 (아이뉴스24). "It can't help but have an immediate effect on SK Hynix's push to list Solidigm, which is in a similar listing situation."
Myoung Shin closed at 10,190 won ($7.70) on October 21. The Kospi rose 3.29% the same day, and MS Autotech rose 5.5%.
