South Korea's Financial Services Commission (FSC) and Korea Exchange (KRX) released new dual listing guidelines on May 6, requiring subsidiaries formed through spin-offs to obtain parent company shareholder approval before pursuing an initial public offering (IPO). The move aims to address longstanding concerns that dual listings — where a listed parent company separately lists a subsidiary — can harm general shareholders through "double-counting" of subsidiary value in both parent and subsidiary stock prices and disrupted dividend flows. Under the new framework, parent company boards must conduct shareholder impact assessments, establish protection measures, and communicate with shareholders before any spin-off subsidiary IPO, marking a shift from permissive practices to a principle of prohibition with limited exceptions.
FSC and KRX Mandate Shareholder Approval for Spin-Off Subsidiary IPOs
The guidelines establish shareholder approval as a mandatory requirement for subsidiaries formed through spin-offs seeking to list on Korean stock exchanges. A dual listing occurs when a listed parent company separately lists a subsidiary, typically to raise capital for subsidiary business expansion or improve management efficiency. The new rules require approval from a majority of attending shareholders and at least one-quarter of total issued shares, with votes in favor of shareholder protection measures. Non-voting shares are excluded from the calculation. Shareholders holding more than 3% of shares have their excess holdings excluded from vote counts, and the largest shareholder's calculation includes shares held by special relationships when determining the 3% threshold.
The KRX will treat applications lacking shareholder approval as failing to meet investor protection requirements. The approval standard applies specifically to subsidiaries established through spin-offs (물적분할), a corporate restructuring method where a parent company transfers assets to a newly created legal entity. General subsidiaries pursuing dual listings that obtain shareholder approval are presumed to have fulfilled obligations to protect minority shareholders, while those without approval undergo individual KRX review considering factors including fundraising necessity, industry characteristics, parent-subsidiary relationship background, and subsidiary weight.
Parent Company Boards Face Enhanced Procedural Obligations
Parent company boards must complete a multi-step process before any spin-off subsidiary IPO. Boards are required to assess the impact of the subsidiary listing on parent company shareholders, develop shareholder protection measures, and conduct shareholder communication or obtain approval through a general meeting or equivalent process. After gathering shareholder opinions and approval results, the board must vote on whether to support the subsidiary listing and notify the subsidiary of the decision. All related information becomes subject to disclosure requirements, including the rationale if shareholder approval procedures were not conducted.
These obligations apply equally when subsidiaries list on overseas exchanges. Boards must establish an independent special committee to review shareholder impact assessments, protection measures, and final approval decisions. The special committee must have at least three members, with the chair being an independent director or with independent directors and external experts comprising at least two-thirds of total members. Shareholder protection measures must be concrete, implementable plans specifying timing, methods, and conditions — not declarative statements. The KRX provided examples including cash dividends, treasury stock cancellations, stock dividends of subsidiary shares, new business investments, profitability improvements, and commitments not to pursue other business splits or subsidiary listings for a defined period.
KRX Expands Dual Listing Review to SPAC Mergers and Overseas Listings
The review framework extends beyond new IPOs to include backdoor listings where listed companies merge with subsidiaries and special purpose acquisition company (SPAC) mergers that achieve equivalent effects. For general subsidiaries not formed through spin-offs, the KRX conducts comprehensive reviews examining operational and management independence. The exchange evaluates whether the subsidiary's core products, services, sales channels, and business model resemble the parent company's, and whether the subsidiary transferred the parent's technology, brand, customer base, or distribution network. Subsidiaries with 50% or more of sales or purchases concentrated with the parent company are presumed to lack operational independence.
Violations of the new requirements trigger financial penalties and trading consequences. Parent company boards that list subsidiaries without fulfilling dual listing obligations face contract penalties of up to 1 billion won. Penalty imposition constitutes grounds for trading suspension. Failure to meet disclosure obligations results in penalty charges or designation as an unfaithful disclosure entity.
Low-Weight Subsidiaries Receive Exemption from Approval Requirement
The KRX exempts certain low-weight subsidiaries from shareholder approval procedures. Subsidiaries with sales, operating profit, and assets all below 10% of the parent company's corresponding figures qualify for the exemption. However, the exemption does not apply if any of the three metrics reaches or exceeds 10%, or if the subsidiary's expected enterprise value exceeds 10% of the parent's value, designating it as a significant subsidiary despite meeting the three quantitative thresholds.
Certain corporate actions fall outside the dual listing special review criteria. Simple personnel spin-offs (인적분할) resulting in newly listed entities and cases where a subsidiary is already listed before the parent company lists are excluded from the special review framework. These transactions remain subject to standard qualitative review criteria applicable to all listings.
