South Korea raises independent director threshold from 22 July.
Listed companies in South Korea face a board reconstitution deadline of 22 July 2026, with a further year to reach full compliance by 22 July 2027, ensuring at least one-third of directors are independent. The change is part of a wider Commercial Code reform promulgated in July 2025, which redefined director appointment, voting and duties.
Although foreign-invested groups with listed Korean entities face the most direct compliance pressure, the director duty changes have broader reach. Groups with Korean board involvement through joint ventures or intra-group arrangements face higher legal risk on decisions affecting minority shareholders. This article covers the new independence ratios, the staged compliance timeline, which entities are in scope and what the expanded director duty means in practice.
Independent director ratio rises to one-third
Amended Article 542-8 renames the outside director as the independent director, signalling that these directors operate independently of management and controlling shareholders. It also raises the threshold, requiring most listed boards to be at least one-third independent, up from one-quarter. Large listed companies, with assets of KRW 2 trillion or more, remain subject to a separate and higher majority-independent requirement.
The reform also tightens audit committee rules. From 23 July 2026, a 3% cap applies to the combined voting rights of controlling shareholders and related parties when appointing or removing audit committee members, limiting their influence over the body meant to oversee them.
Both changes build on a 2025 reform already in force, which requires directors to owe their duties to shareholders as well as the company. That shift raised expectations around fairness in transactions such as related party deals, mergers and spin-offs.
Why the July 2026 deadline requires early preparation
Korean boards have traditionally been dominated by controlling shareholders, with limited influence from minority and foreign investors. Raising the independent director ratio and tightening voting caps aim to rebalance this dynamic and improve investor confidence.
For companies in scope, 22 July 2026 is a compliance point, not a planning milestone. Identifying qualified independent directors, verifying their independence and securing shareholder approval all take time, so a board below the threshold cannot wait until the deadline to act.
Board composition steps for in-scope Korean entities
The requirement applies to listed companies, so the immediate impact falls on foreign groups with a listed Korean subsidiary or affiliate. The first step is to confirm which entities are in scope and measure each board against the one-third standard. Where there is a shortfall, it should be quantified now and an appointment timeline mapped back from the next general meeting.
Expanded director duty and group transaction risk
The impact extends beyond board composition. Now that directors owe duties directly to shareholders, decisions involving intra-group transactions, restructurings and related party dealings carry higher legal risk for Korean boards. Groups with any Korea exposure, including joint ventures or M&A activity, should ensure these decisions are properly documented and approved.
Interpretation of the expanded duty is still evolving, so reviewing board composition, independence and decision-making records ahead of the deadline is the most practical way to manage risk.
