Shareholder Activism Expands in South Korea, Pressuring Chaebol Governance
A decades-long shift in Korean corporate culture, from the first foreign activist campaigns in 1999 to today's domestic funds, is testing whether legal and structural reforms can overcome...
South Korea's corporate governance landscape is undergoing a measurable change as shareholder activism, once an almost exclusively foreign practice, has taken root among domestic investors. The shift spans more than two decades and is now drawing scrutiny from policymakers, institutional investors, and international markets alike, according to a Korea Times cover story published September 6, 2026.
The first significant case of foreign shareholder activism in Korea arrived in 1999, when U.S. Hedge fund Tiger Management acquired a 6.6 percent stake in SK Telecom, the country's largest wireless carrier, according to the Korea Times. Tiger Management used the position to press for changes including stronger external oversight of management, a demand that was largely novel in a market where founding families typically maintained decisive control through cross-shareholding structures.
At the time, South Korea had only recently emerged from the 1997 to 1998 Asian financial crisis, which forced the government to open capital markets more widely to foreign investors as part of International Monetary Fund reform conditions. That opening created the access that foreign funds needed to build stakes in publicly listed Korean companies, setting the conditions for activist campaigns to follow.
The chaebol system, in which large family-controlled conglomerates such as Samsung, Hyundai, SK, and LG dominate the economy, has historically concentrated governance authority with founding families despite their often-small direct ownership stakes. Circular shareholding arrangements, in which subsidiaries hold shares in each other and in the parent group, have allowed founding families to exercise control disproportionate to their economic ownership, a structure that activists have repeatedly challenged in filings and at shareholder meetings.
The Korea Times report notes that activism has since evolved from foreign-led campaigns to include Korean domestic funds, with firms such as Align Partners Capital Management among those now publicly engaging Korean companies on governance, capital allocation, and dividend policy. This domestication of activism is a notable development because Korean institutional investors, including the National Pension Service, which is one of the largest pension funds in the world by assets, have historically been reluctant to vote against management recommendations.
The National Pension Service managed assets exceeding 1,000 trillion Korean won as of data reported in 2025 by Korean financial regulators, giving it significant potential influence across major listed companies. Advocates of stronger governance have called on the fund to use its voting rights more assertively, while critics have cautioned that aggressive activist positions could disrupt long-term corporate relationships.
South Korea's Financial Services Commission introduced a series of governance reform measures in recent years, including updates to the Korea Corporate Governance Code, which operates on a comply-or-explain basis and requires listed companies to disclose why they deviate from recommended governance practices. The government also launched a "Corporate Value-up" program in 2024, modeled partly on similar initiatives in Japan, intended to encourage companies trading below book value to take steps to improve returns to shareholders, according to Financial Services Commission announcements.
Japan's comparable experience offers a reference point. The Tokyo Stock Exchange began requiring companies with price-to-book ratios below 1.0 to publicly disclose improvement plans beginning in 2023, a policy credited by analysts at multiple institutions with contributing to increased share buybacks and dividend increases among Japanese firms. South Korean officials cited the Japanese model when designing their own program, though structural differences between the two markets, particularly the chaebol ownership structure, complicate direct comparison.
Activist campaigns in Korea have not been uniformly successful. Founding families and friendly institutional shareholders have blocked resolutions at general meetings, and Korean courts have in some instances upheld governance arrangements that critics argued entrenched management. The legal framework governing shareholder rights, including rules on cumulative voting for board directors and limits on treasury share voting, has been a recurring point of contention between activists and management.
What remains uncertain is whether the current combination of government reform programs, growing domestic activism, and international investor pressure will produce durable changes in board composition and capital return practices at Korea's largest companies, or whether founding families will retain effective control through existing structural mechanisms. Tracking votes at annual general meetings and changes in board independence ratios at the top 50 listed companies by market capitalization would provide the clearest measure of progress over the next several proxy seasons.
