South Korea's 3% Voting Cap for Audit‑committee Elections (effective 2026): Board & Investor Checklist

The 3 percent voting cap in South Korea is no longer confined to the election of statutory auditors, it now extends to audit‑committee elections under the 2025 amendments to the Commercial Act (Act No. 20991), promulgated on July 22, 2025. For any shareholder meeting held on or after July 22, 2026, a shareholder who is the largest shareholder (along with related parties) may exercise voting rights equivalent to no more than 3% of total issued and outstanding shares when appointing or dismissing audit‑committee members. This single change reshapes proxy strategy, meeting‑notice preparation, vote‑tallying processes and custodian coordination for hundreds of listed companies and the institutional investors that hold stakes in them.

Boards, general counsel and investor‑relations teams that have not yet updated their AGM playbooks face a narrow compliance window before the next shareholder meeting season.

Executive Summary: The New 3% Voting Cap in South Korea at a Glance

The amended Article 542‑12 of the Commercial Act caps the voting power of a company’s largest shareholder and its related parties at 3% of total issued shares during votes on audit‑committee member appointments and dismissals. Previously, this audit committee voting limit applied only to companies with total assets of KRW 2 trillion or more. Following the Commercial Act amendment in Korea, the restriction is broadened and strengthened, covering a wider category of listed companies and closing several structural workarounds that controlling shareholders previously relied upon.

Here are the four actions that boards and investors should take immediately:

• Review articles of incorporation. Confirm that charter provisions on audit‑committee elections reflect the new 3% cap and do not conflict with the amended statute.
• Update AGM notices and proxy forms. Meeting notices for any shareholder meeting held after July 22, 2026 must clearly describe the voting restriction and the mechanics for calculating the cap.
• Coordinate with custodians and registrars. Foreign shareholders holding through omnibus or pooled accounts should confirm how the 3% aggregation will be applied at the record‑holder level.
• Model vote‑allocation scenarios. Institutional investors holding more than 3% should prepare split‑voting strategies and proxy instruction protocols before the next AGM season.

Legal Background and Effective Dates: 3 Percent Voting Cap South Korea Timeline

The legislative journey of the 3% voting cap extension began with bipartisan proposals to strengthen corporate governance in Korea by reducing the ability of controlling shareholders to dominate audit oversight. The amendment received bipartisan support at subcommittee level in early July 2025 and moved swiftly to a plenary vote. Different provisions of Act No. 20991 carry different enforcement dates, which is a critical detail that boards must track carefully.

Industry observers expect regulators, particularly the Financial Services Commission (FSC) and the Financial Supervisory Service (FSS), to issue supplementary enforcement guidance before the July 2026 effective date, clarifying edge cases around aggregation, transitional treatment for meetings already convened, and interaction with existing listing rules on the Korea Exchange (KRX). Companies with a December fiscal year‑end that hold their AGMs in March should note that the March 2027 AGM season will be the first routine cycle fully subject to the new cap.

Who Is Covered: Entities, Shareholders and Thresholds Under the 3% Voting Cap

Before the 2025 amendment, the 3% voting restriction on audit‑committee elections applied primarily to listed companies whose total assets equalled or exceeded KRW 2 trillion. The Commercial Act amendment in Korea extends the scope so that it covers a broader range of listed companies, bringing mid‑cap issuers into compliance for the first time.

Defining the “largest shareholder” and related parties

The cap applies to the largest shareholder, defined as the person who holds the most shares in the company, including shares held in their own name and those controlled through related parties. Related parties include spouses, lineal blood relatives, companies in which the largest shareholder holds a controlling interest, and any person who has entered into a joint‑exercise agreement for shareholder voting rights in South Korea.

The aggregation mechanism is crucial. Suppose the largest shareholder personally holds 5% and a related‑party entity holds a further 4%, for a combined 9%. When voting on an audit‑committee election, this bloc may cast votes equivalent to only 3% of total issued shares. The remaining 6% is neutralised for that agenda item only, it does not affect voting on other matters such as director elections outside the audit committee or dividend approvals.

Arithmetic example

Consider a KOSPI‑listed company with 100 million total issued shares. The largest shareholder group holds 12 million shares (12%). At an audit‑committee election, the group may exercise only 3 million votes (3%). A minority shareholder holding 2.5 million shares (2.5%) faces no restriction and can exercise all 2.5 million votes. This rebalancing is designed to give minority and institutional investors materially greater influence over audit oversight appointments, a core objective of the corporate governance Korea reforms.

Mechanics: How Votes Are Counted, Treasury Shares and Cumulative Voting

Vote‑counting under the 3% cap

The 3% ceiling is calculated on the basis of total issued and outstanding voting shares. The company’s share registrar or transfer agent must identify the largest shareholder and aggregate the holdings of all related parties before the meeting. Votes cast in excess of 3% on an audit‑committee election agenda item are not counted. The remaining shareholders’ votes are tallied without any cap.

Treasury shares

Treasury shares held by the company carry no voting rights under existing Commercial Act provisions. They are excluded from the denominator when calculating total outstanding voting shares. This means the 3% threshold is applied to a slightly smaller base, which can marginally reduce the absolute number of votes the largest shareholder may cast. Companies should recalculate the cap each time they repurchase or dispose of treasury shares ahead of a record date.

Interaction with cumulative voting

The 3% cap applies irrespective of whether the company uses cumulative or straight voting for audit‑committee elections. Where cumulative voting is in effect, the largest shareholder’s total vote pool for audit‑committee candidates is still capped at 3% of total voting shares multiplied by the number of audit‑committee seats being elected. The practical effect is that cumulative voting does not circumvent the restriction, it merely distributes the capped vote pool across candidates.

Practical Checklist for Boards and Company Secretaries: Shareholder Meeting Compliance Playbook

The following timeline provides a step‑by‑step action plan for companies preparing for shareholder meetings subject to the new 3% voting cap in South Korea. Adjust calendar references to your company’s fiscal year‑end and meeting date.

• T‑120 days (board strategy session). Commission an internal review of the company’s articles of incorporation. Identify any provisions that reference audit‑committee election procedures and confirm they are consistent with the amended Article 542‑12. If the charter contains a higher voting‑cap threshold or no explicit reference, prepare a board resolution to propose an amendment at the next AGM.
• T‑90 days (registrar coordination). Instruct the share registrar or transfer agent to prepare an updated largest‑shareholder analysis as of the expected record date. Confirm the methodology for identifying related parties and aggregating holdings. Request a test run of the vote‑tallying system to ensure it can automatically cap votes at 3% for the audit‑committee agenda item.
• T‑60 days (proxy form and notice drafting). Update AGM notice templates to include a clear explanation of the 3% voting restriction for audit‑committee elections. Recommended notice language: “Pursuant to Article 542‑12 of the Commercial Act, as amended by Act No. 20991, shareholders who are the largest shareholder and their related parties may exercise voting rights equivalent to no more than 3% of total issued and outstanding voting shares for Agenda Item [X] (appointment of audit‑committee member). Votes in excess of this threshold will not be counted.”
• T‑30 days (board resolution). Approve the final AGM agenda, meeting notice and proxy materials by board resolution. Suggested resolution clause: “RESOLVED, that the Company shall apply the 3% voting restriction under Article 542‑12 of the Commercial Act to all agenda items relating to the appointment or dismissal of audit‑committee members, and that the share registrar is authorised to exclude votes cast in excess of this threshold.”
• T‑14 days (meeting notice dispatch and disclosure). Dispatch the meeting notice within the statutory notice period. File the notice and related proxy materials with the KRX disclosure system (KIND). Ensure the disclosed materials reference the 3% cap and identify the agenda items to which it applies.
• T‑7 days (custodian and IR outreach). Contact major custodians (particularly those holding shares for foreign investors) to confirm that proxy instructions for the audit‑committee agenda item will be processed in compliance with the cap. Provide IR briefing materials to institutional shareholders explaining the voting mechanics.
• Meeting day (vote tallying and announcement). The chairman or scrutineer must verify the largest‑shareholder aggregation before counting votes on the audit‑committee item. Announce both the raw vote count and the adjusted count (after applying the 3% cap) to the meeting. File post‑meeting vote results with the KRX within the required disclosure window.

Institutional Investors and Foreign Shareholders: Voting Strategy Playbook

The 3% cap directly affects only the largest shareholder group, but its indirect consequences for institutional investor voting in Korea are substantial. By neutralising a large portion of controlling‑shareholder votes on audit‑committee matters, the amendment amplifies the relative weight of every other shareholder’s vote. Institutional investors with even modest holdings may find they hold decisive influence over audit‑committee composition for the first time.

Proxy instruction splitting and vote allocation

An asset manager holding 7% of a company’s shares through a single custodial account is not subject to the 3% cap (assuming it is not part of the largest shareholder group). It can exercise all 7% of its votes on audit‑committee items. However, if the same manager holds shares across multiple funds or mandates, each with distinct beneficial owners, the proxy voting rules in Korea require that instructions be submitted per beneficial owner. Managers should ensure their proxy platforms can handle split instructions, voting different funds in different directions on the same agenda item, and that custodians transmit these instructions accurately to the registrar.

Pooled custodial accounts and omnibus structures

Foreign investors frequently hold Korean equities through omnibus accounts maintained by global custodian banks. The 3% cap is applied at the level of the largest shareholder and its related parties, not at the custodian level. A global custodian that is the record holder of 20% of a company’s shares on behalf of dozens of underlying clients is not itself subject to the cap (unless one of its underlying clients is the largest shareholder or a related party). However, companies and their registrars may require the custodian to provide a breakdown of beneficial ownership to verify that no single beneficial owner within the omnibus structure is the largest shareholder. Custodians should anticipate increased requests for beneficial‑ownership certification ahead of record dates.

Share lending and record‑date issues

Shareholders who lend shares before the record date lose voting rights for that meeting. Industry observers expect that some market participants may attempt to restructure their holdings via securities lending to influence the identity of the “largest shareholder” for cap purposes. Regulators and the KRX are likely to scrutinise unusual lending activity around record dates, and any arrangement designed to artificially reduce a shareholder’s apparent holding to avoid the cap could face regulatory challenge under existing securities‑law provisions on market manipulation and false disclosure.

Sample vote‑allocation scenario

A global pension fund holds 4.5% of a KOSPI‑listed company and is not part of the largest shareholder group. The largest shareholder group holds 18% but is capped at 3%. Total voting shares: 200 million. At an audit‑committee election (single seat), the effective votes are:

• Largest shareholder group: 6 million votes (3% of 200 million), despite holding 36 million shares.
• Pension fund: 9 million votes (4.5% of 200 million), full exercise.
• All other shareholders: full exercise of their combined holdings (remaining shares).

The pension fund’s 9 million votes now exceed the controlling shareholder’s capped 6 million votes, giving it, along with other minority and institutional holders, a decisive voice in the election. This dynamic is expected to increase engagement by institutional investors ahead of audit‑committee votes, and foreign companies investing in South Korea should factor this shift into their governance risk assessments.

Enforcement, Dispute Mechanisms and Regulatory Guidance

The FSC and FSS are the primary regulatory bodies overseeing compliance with shareholder voting rights in South Korea, while the KRX enforces listing‑rule obligations around disclosure. Likely enforcement channels include the following:

• Disclosure review. The KRX may review post‑meeting vote disclosures to confirm that companies correctly identified the largest shareholder group, applied the 3% cap, and reported adjusted vote counts.
• Shareholder petitions. Minority shareholders may petition the court to invalidate an audit‑committee election resolution if the 3% cap was not properly applied, under the existing provisions for challenging shareholder meeting resolutions (Article 376 of the Commercial Act).
• Regulatory sanctions. The FSS may impose corrective orders or administrative penalties on companies or their directors that fail to comply with the voting‑cap requirements.
• Recount procedures. Where a dispute arises over vote tallying, shareholders may request a formal recount through the meeting chairman or seek a court‑supervised inspection of the share register and proxy records.

The likely practical effect is that companies will face heightened scrutiny of their AGM procedures during the first full cycle under the amended rules, making thorough preparation and documentation essential. Companies that proactively engage experienced Korea corporate lawyers to review their voting processes will be better positioned to withstand any post‑meeting challenges.

Templates and Practical Annexes

To support shareholder meeting compliance, the following templates and reference materials can be adapted to individual company circumstances. These are illustrative starting points and should be reviewed by qualified Korean corporate counsel before use.

• Board resolution clause (sample). “The Board resolves that, in accordance with Article 542‑12 of the Commercial Act as amended by Act No. 20991, the voting rights of the largest shareholder and related parties shall be limited to 3% of total issued and outstanding voting shares for all agenda items relating to the appointment or dismissal of audit‑committee members at the [Year] Annual General Meeting.”
• Meeting notice paragraph (sample). “Shareholders are advised that, pursuant to the amended Commercial Act, the largest shareholder and related parties may exercise voting rights equal to no more than 3% of the Company’s total issued and outstanding voting shares on Agenda Item [X]. Votes exceeding this limit will be excluded from the tally. All other shareholders may exercise their full voting entitlement.”
• Proxy instruction split table (example). A custodian holding shares for three underlying beneficial owners (Fund A: 2.1%, Fund B: 1.8%, Fund C: 0.9%) should submit three separate proxy instructions. None of these funds individually triggers the 3% cap (assuming none is the largest shareholder), so each exercises its full allocation.
• Vote reconciliation checklist. Registrars should prepare a reconciliation document before each meeting confirming: (a) identity of the largest shareholder, (b) aggregated related‑party holdings, (c) total issued voting shares (net of treasury shares), (d) calculated 3% threshold, and (e) excess votes to be excluded.

Conclusion and Next Steps

The extension of the 3 percent voting cap in South Korea to audit‑committee elections marks a structural shift in corporate governance, giving minority and institutional investors materially greater influence over audit oversight. Companies and investors should act now by completing five priority tasks: reviewing articles of incorporation, updating AGM notice templates, coordinating with registrars and custodians, modelling vote‑allocation scenarios, and monitoring forthcoming FSC and KRX guidance. Boards that prepare early will turn a compliance obligation into an opportunity to strengthen their governance credentials, while investors that understand the new mechanics will be positioned to exercise meaningful influence at the next shareholder meeting season.

For jurisdiction‑specific guidance on how these changes interact with cross‑border tax obligations or other Korean regulatory requirements, seek qualified legal advice tailored to your company’s structure and shareholder base.
