This is an analysis of the background and evaluation of the accelerating trend of unwinding parent-child listings in Japan.
Key Points
1. Current Status and Characteristics of Parent-Child Listings
- In Japan, cases where a public company holds 20% or more of another public company's shares, becoming a controlling shareholder, account for 32% of all such arrangements.
- In the US and UK, institutional investors are the dominant shareholders, with the ownership ratio of business corporations standing at only 5-6% (as of 2012).
- In continental Europe and South Korea, the characteristic structure is a pyramid with founding families or asset management firms at the top as controlling shareholders.
- The performance of companies in parent-subsidiary relationships was not found to be lower than that of independent companies of a similar industry and scale.
2. Acceleration in Unwinding Parent-Child Listings
- The number of listed subsidiaries peaked at 467 at the end of fiscal 2007, decreasing to 233 by the end of fiscal 2023.
- Since fiscal 2019, in addition to turning subsidiaries into wholly-owned entities (traditionally 60% of cases), divestitures have increased to account for over 20% of dissolutions.
- Of its 16 listed subsidiaries in 2009, Hitachi, Ltd. has made 7 wholly-owned, sold 5 to domestic and international companies, and sold 3 to private equity funds.
3. Four Factors Driving the Acceleration
- Increased criticism from shareholders: In addition to activists, traditional institutional investors are paying more attention to the parent company's capital efficiency.
- Negative stance from the government and stock exchanges: Since 2019, there has been a greater focus on conflict-of-interest issues, and in 2023, a request was made for companies with a PBR below 1.0x to make improvements.
- Constraints on group management: Agile business restructuring and M&A strategies where the subsidiary is the acquirer are restricted, as they require the approval of the subsidiary's shareholders.
- Diversification of buyers: Buyout funds have grown in importance as potential buyers, offering management expertise and global networks.
4. Evaluation and Future Challenges
- Unwinding parent-child listings is desirable for realizing integration benefits, improving capital efficiency, preventing conflicts of interest, and enhancing corporate governance.
- For emerging companies with abundant growth opportunities, such as in the IT industry, the rationale for investment by corporate entities remains strong.
- If a parent company wishes to maintain its status as a controlling shareholder, it is essential to provide a specific and quantitative explanation of its rationale from the perspective of increasing corporate value and capital efficiency.
- Turning a subsidiary into a wholly-owned entity involves significant costs due to rising acquisition premiums, which are not easily offset by organizational improvements alone.
The article concludes that while the unwinding of parent-child listings is a desirable trend in line with structural changes, a rationale for their existence persists for growth companies. In cases where they are maintained, accountability and the protection of minority shareholders are crucial.
