Korea Bans Conglomerate Subsidiary IPOs in Major Market Reform

The Korean government's decision to ban dual listings of subsidiaries by listed companies is being interpreted as an extraordinary measure to establish market order and provide clear IPO standards. While companies in select future industries may apply for preliminary listing reviews through parent company board resolutions, other firms now face significant barriers to stock market debuts. Industry observers say companies that have relied on subsidiary IPOs for funding are scrambling to find alternative financing methods.

According to investment banking sources on March 15, financial authorities plan to announce dual listing regulations at a "Capital Market Stability and Normalization Meeting" chaired by President Lee Jae-myung on March 18. Financial Services Commission Chairman Lee Eok-won, Financial Supervisory Service Governor Lee Chan-jin, KOSDAQ and KONEX listed company officials, and institutional investors will attend. The meeting will present four major reform measures to improve capital market fundamentals, with dual listing regulations as the centerpiece. President Lee reportedly received a briefing on the reform details at a senior staff meeting before the March 18 meeting schedule was announced.

Authorities will prohibit all new listings by companies with listed parent firms. The regulation covers all companies belonging to large business groups under the Fair Trade Act and unlisted subsidiaries where listed parents hold 30% or more equity. Large business groups are conglomerates with combined affiliate assets exceeding 5 trillion won—92 groups under last year's designation. These groups include 2,930 unlisted affiliates. Mid-sized companies also fall under the regulation when listed parents exercise control through 30% or more ownership.

Exceptions will allow listing applications for companies in national strategic high-tech industries. This accommodates industry practices of funding investments through subsidiary IPOs and supports growth engines in advanced industries. However, even with exceptions, new listings require parent company board approval and minority shareholder protection measures such as in-kind dividends of IPO shares. Industry consensus holds that pursuing dual listings has become virtually impossible.

Many unlisted conglomerate affiliates pursuing market debuts face urgent challenges. Hanwha Energy, with stakes divided among Hanwha Group's third-generation owners, selected Korea Investment Securities, NH Investment Securities, and Daishin Securities as IPO underwriters last year. Investment bankers then believed Hanwha Energy would not constitute a dual listing since individuals—not corporations—held majority stakes. The new regulations are expected to derail these IPO plans. DN Solutions under DN Automotive, SK Ecoplant with SK Inc. as largest shareholder, and HD Hyundai Robotics under HD Hyundai Inc. also face IPO obstacles.

The government's aggressive regulation aims to enhance stock market value through shareholder protection. Dual listings have sparked numerous controversies in Korean capital markets. LG Energy Solution, spun off from LG Chem, and LS Group's Essex Solutions have been at the center of such disputes. Dual-listing subsidiaries operating core businesses can diminish corporate value and harm shareholders. President Lee previously criticized dual listings, saying: "If you buy a pregnant cow but someone else owns the calf, wouldn't you be angry?"

The regulation is expected to fundamentally change how conglomerates raise capital. With IPO financing constrained, companies may issue mezzanine instruments such as exchangeable bonds or derivatives like price return swaps using subsidiary stakes. As dual listing controversies intensified last year, exchangeable bond issuance reached 4.78 trillion won—more than double the 1.98 trillion won in 2024.

An investment banking official said: "As subsidiary dual listings become difficult, more cases of securitizing held shares for investment funding will emerge. Some conglomerates are expected to sell non-core assets, fundamentally transforming capital markets."
