Corporate Lawyers South Korea 2026: Treasury Stock, Independent Directors and Disclosure, Compliance Guide

Corporate lawyers South Korea practitioners are advising need to act quickly: on 25 February 2026 the National Assembly passed sweeping revisions to the Korean Commercial Act that impose mandatory cancellation of newly acquired treasury stock, strengthen independent director requirements and expand disclosure obligations for listed companies. The Financial Services Commission (FSC) announced related rule changes on 24 February 2026, with subordinate regulations scheduled to take full effect by 30 December 2026. This compliance guide provides boards, general counsel and CFOs with the practical checklists, timelines and template language needed to implement the Korean Commercial Code amendment before each deadline arrives.

Immediate 5-point action checklist:

1. Within 30 days: Inventory all treasury stock holdings by purpose, acquisition date and volume.
2. Within 60 days: Draft a Holding & Disposal Plan for any shares to be retained under a statutory exception (ESOP, employee compensation, regulatory compliance).
3. Within 90 days: Update board-skills matrices, confirm independent director ratios and prepare nomination-committee documentation.
4. Within 120 days: Begin drafting a corporate value-up plan for FSC/KRX filing if the company falls within the high-dividend or large-cap disclosure tier.
5. Within 180 days: Finalise AGM notice language, shareholder materials and investor-relations messaging to reflect the new rules ahead of the 30 December 2026 subordinate-regulation effective date.

What Changed, The Commercial Act 2026 at a Glance

The revisions approved by the National Assembly on 25 February 2026 represent the most significant overhaul of South Korea’s corporate governance framework in over a decade. Widely characterised as a measure aimed at boosting share valuations and closing the persistent “Korea discount,” the legislation recalibrates the balance between shareholder returns, board accountability and market transparency.

Key Statutory Changes

• Mandatory treasury-stock cancellation (buyback cancellation rule): Companies that repurchase their own shares must, in principle, cancel those shares within one year of acquisition. Retention is permitted only where the shares serve a specific statutory purpose, principally employee stock-ownership plans (ESOPs), stock-based compensation schemes or compliance with sector-specific regulatory requirements.
• Strengthened independent director duties: The amendments raise the bar for director independence in Korea, tightening eligibility criteria, expanding fiduciary duties and reinforcing the role of outside directors on audit and nomination committees.
• Enhanced disclosure obligations: Listed companies, particularly those on the KOSPI with high dividend payouts, must file corporate value-up plans with the KRX and the FSC, and large-cap companies face phased-in English-language disclosure requirements beginning May 2026.
• Expanded shareholder protections: The revisions introduce clearer standards for board decision-making on capital allocation and require more granular reporting on the rationale behind treasury-share retention.

Who Is Affected

The mandatory cancellation rule and disclosure changes apply most directly to companies listed on the KOSPI and KOSDAQ markets. However, non-listed companies subject to foreign-investment regulations or sector-specific rules (such as telecommunications and defence) may also be affected, with some sectors benefiting from a three-year transition period. Every entity that holds or plans to acquire treasury stock should assess its position under the revised framework.

Timeline and Implementation Calendar for Listed Company Compliance 2026

Understanding the sequence of deadlines is critical for boards and compliance teams. The table below consolidates the key legislative and regulatory dates into a single reference calendar. Corporate law South Korea practitioners should treat this as the baseline planning tool for the months ahead.

Early indications suggest the FSC will issue additional guidance circulars during Q3 2026, particularly on the mechanics of filing corporate value-up plans and the transitional treatment of previously acquired treasury stock. Boards should build flexibility into their compliance calendars to absorb these expected updates.

Treasury Stock Korea, What the Law Requires and the Key Exceptions

The mandatory cancellation rule is the centrepiece of the Commercial Act 2026 reform. Its practical impact on capital structure, dividend policy and earnings-per-share calculations makes it the single most urgent compliance priority for Korean corporate lawyers and the boards they advise.

The general rule: Any company that acquires its own shares, whether through open-market buybacks, tender offers or trust arrangements, must cancel those shares within one year of the acquisition date, in principle. Cancellation reduces the issued share count permanently and is irrevocable.

Statutory exceptions, when retention is permitted:

• Employee stock-ownership plans (ESOPs): Shares held for distribution to employees under a registered ESOP may be retained, provided a Holding & Disposal Plan has been filed and approved at the company’s annual general meeting.
• Stock-based compensation: Treasury shares earmarked for executive or employee compensation programmes qualify for retention, subject to the same filing and AGM-approval requirements.
• Regulatory compliance: Where sector-specific regulations require a company to maintain a minimum shareholding ratio or capital buffer (for example, in defence, telecommunications or financial services), retention is allowed for the duration of that regulatory obligation.
• Transitional holdings: Shares acquired before the effective date of the amendment will be subject to transitional rules. Industry observers expect these to provide a grace period, likely aligned with the 30 December 2026 subordinate-regulation effective date, though companies should not assume automatic exemption and must track official FSC circulars closely.

Step-by-step compliance checklist for treasury stock Korea obligations:

1. Compile a complete register of all treasury-share holdings, classified by purpose (buyback, ESOP allocation, compensation reserve, regulatory buffer) and acquisition date.
2. For shares not covered by a statutory exception: schedule a cancellation timeline within the one-year window; prepare the board resolution authorising cancellation.
3. For ESOP or compensation-allocated shares: draft and file the Holding & Disposal Plan with the KRX; add the plan to the AGM agenda for shareholder approval.
4. Engage auditors to model the accounting impact of cancellation on equity, EPS and dividend-payout ratios.
5. Notify the investor-relations team and prepare market-facing communications explaining the planned cancellations and any retained positions.

Sample Board Resolution Language, Treasury-Share Cancellation

The following is illustrative only and must be adapted to the company’s specific articles of incorporation and legal circumstances.

“RESOLVED, that [Company Name] shall cancel [number] ordinary shares of treasury stock acquired on [date(s)], having a total book value of KRW [amount], in compliance with Article [X] of the amended Commercial Act. The Board directs management to file the requisite notifications with the Korea Exchange and the Financial Services Commission within [Y] business days and to update the share register accordingly.”

Practical Pitfalls and Drafting Tips

• Repurchase via trust: Where a company has engaged a trust company to execute buybacks, confirm whether the trust deed triggers the one-year clock from the date the trust acquires the shares or the date the shares are transferred back to the company. The answer affects the cancellation deadline.
• Reissuance timing: If the company contemplates reissuing treasury shares for M&A consideration or a secondary offering, the buyback cancellation rule effectively closes that window once the one-year period expires. Plan any reissuance well before the deadline.
• Tax treatment: Cancellation of treasury shares may trigger deemed-dividend or capital-gains tax consequences depending on the method of original acquisition. Engage tax counsel early.

Independent Directors and Board Composition Under the Director Independence Korea Reforms

The 2026 amendments reinforce the expectation that listed companies will maintain genuinely independent board oversight. For boards, this means reviewing both the composition of the board and the processes by which independent directors are nominated, elected and evaluated.

Key changes to director independence Korea requirements:

• Tightened eligibility criteria: The revised Commercial Act narrows the definition of “independence,” imposing stricter cooling-off periods for former employees, executives and significant shareholders, and extending disqualification to family members of controlling shareholders.
• Expanded fiduciary duties: Independent directors now bear explicit statutory responsibility for overseeing capital-allocation decisions, including treasury-stock transactions and dividend policy, adding a new layer of personal liability.
• Nomination-committee strengthening: Companies are expected to demonstrate that their nomination committees operate independently of management, with documented selection criteria and a skills-matrix approach to board composition.

Practical steps for compliance:

1. Update the board-skills matrix to reflect the new independence criteria and identify any sitting directors who may no longer qualify.
2. Amend the company’s articles of incorporation if needed to align with the revised minimum ratios for independent directors and audit-committee composition.
3. Prepare independence-attestation letters for each outside director, confirming compliance with the new eligibility standards.
4. Review nomination-committee terms of reference and document the selection process for any upcoming board elections.

Draft Language for Director Independence Attestation

“I, [Director Name], hereby confirm that I satisfy all independence requirements set out in Articles [X] and [Y] of the amended Commercial Act and the relevant KRX Listing Rules. I have no material relationship with [Company Name], its controlling shareholders, or their family members, and I have not been employed by or provided paid advisory services to the company within the prescribed cooling-off period.”

Board Minutes and Evidence-Retention Checklist

• Record the independence determination for each director in official board minutes at least annually.
• Retain all nomination-committee meeting records, candidate-evaluation materials and conflict-of-interest declarations for a minimum of five years.
• Maintain a centralised register of related-party relationships for each director, updated quarterly.

Disclosure Obligations and FSC/KRX Expectations, Dividend Disclosure Requirements

The FSC’s announcement on 24 February 2026 introduced new dividend disclosure requirements and the corporate value-up plan framework. These changes are designed to improve transparency around capital allocation, reduce information asymmetry for foreign investors and encourage companies to adopt shareholder-friendly policies.

What to Include in a Corporate Value-Up Plan

While the FSC has not yet published a prescriptive template, its guidance indicates that a compliant corporate value-up plan should address, at a minimum, the following items:

• A statement of the company’s capital-allocation philosophy, including dividend policy, buyback strategy and reinvestment priorities.
• Quantitative targets for shareholder returns (e.g., dividend-payout ratio, total-return targets over a stated period).
• A summary of treasury-share holdings and the rationale for any shares retained under a statutory exception.
• Governance measures in place to oversee capital allocation, including the role of independent directors and the audit committee.
• A timeline for review and public reporting on progress against stated targets.

Reporting Obligations by Entity Type

The phased introduction of mandatory English-language disclosure for KOSPI large-cap companies, beginning in May 2026, is a particularly significant development for foreign institutional investors and the corporate lawyers South Korea firms that advise them. Companies should build bilingual disclosure workflows into their compliance infrastructure now rather than scrambling to translate documents under deadline pressure.

Drafting and Board Governance Playbook

Translating legislative text into board-ready processes is where compliance either succeeds or fails. The following playbook provides a structured approach for GCs and company secretaries managing the implementation.

30/60/90/180-day plan:

• Days 1–30: Complete the treasury-stock inventory; convene an emergency board session to discuss the amendments; assign a project lead (typically the GC or company secretary).
• Days 31–60: Finalise the Holding & Disposal Plan for retained treasury shares; begin the board-skills-matrix review; engage external counsel for a gap analysis.
• Days 61–90: Draft AGM agenda items, shareholder-notice language and proxy materials reflecting the new requirements; prepare investor-relations Q&A scripts.
• Days 91–180: File the corporate value-up plan (if applicable); complete English-disclosure setup; update internal disclosure controls and sign-off workflows ahead of the 30 December 2026 effective date.

Sample AGM Notice Language

“Agenda Item [X], Approval of Treasury-Share Holding & Disposal Plan: The Board proposes that shareholders approve the retention of [number] ordinary shares for the purpose of [ESOP allocation / stock-based compensation], in accordance with Article [X] of the amended Commercial Act. Full details of the plan, including the intended disposal timeline and the accounting impact, are set out in the accompanying materials.”

Audit Committee and Disclosure-Control Checklist

• Confirm that the audit committee’s terms of reference explicitly cover oversight of treasury-stock transactions and capital-allocation disclosures.
• Review and, if necessary, update the company’s disclosure-control framework to include sign-off gates for treasury-share filings and corporate value-up plan submissions.
• Schedule a pre-filing review session with external auditors to verify the accuracy of financial data included in disclosures.
• Document the disclosure-approval chain (drafter → legal review → audit-committee sign-off → filing) and retain records for a minimum of five years.

Risk Scenarios and Enforcement

The FSC has signalled that enforcement of the new rules will be proactive rather than reactive. In press releases accompanying the 24 February 2026 announcement, the regulator emphasised its intention to monitor compliance closely and to use its existing enforcement toolkit, including administrative sanctions, public censure and referral for criminal prosecution in severe cases, to deter non-compliance.

Key risk scenarios boards should prepare for:

• Failure to cancel treasury stock within the one-year window: The likely practical effect will be regulatory sanction by the FSC and potential delisting review by the KRX. Market reaction could include a share-price discount as investors interpret non-compliance as a governance red flag.
• Inadequate disclosure in the corporate value-up plan: Companies that file plans lacking substance may face FSC information requests, public comment letters or mandatory re-filings, all of which carry reputational risk.
• Board-composition deficiencies: If a listed company’s independent-director ratio falls below the revised statutory minimum following a director resignation or disqualification, the company must remedy the shortfall within the prescribed period or face trading restrictions.

The recommended escalation workflow is straightforward: identify the issue internally, engage Korean corporate lawyers for a legal assessment, prepare a remediation plan and notify the FSC or KRX proactively if a deadline will be missed. Regulators typically respond more favourably to companies that self-report and demonstrate good faith.

Practical Templates for Immediate Use

Below are two skeleton templates designed to give boards and GCs a starting framework. Both must be customised to the company’s specific circumstances and reviewed by qualified corporate counsel before use.

Template 1, Treasury-Share Disposal Resolution:

“RESOLVED, that in accordance with [Company Name]’s Holding & Disposal Plan approved at the [date] AGM, the Board authorises management to dispose of [number] treasury shares allocated for [ESOP distribution / compensation award] to eligible employees on or before [date], at a disposal price determined by [pricing mechanism]. Management shall file all requisite notifications with the KRX within [Y] business days of disposal.”

Template 2, Corporate Value-Up Plan Skeleton:

1. Capital-Allocation Philosophy: [State dividend policy, buyback strategy, reinvestment priorities.]
2. Shareholder-Return Targets: [Quantitative targets, e.g., dividend-payout ratio of X% over Y years.]
3. Treasury-Share Summary: [Number of shares held, purpose, statutory basis for retention.]
4. Governance Oversight: [Role of independent directors and audit committee in capital-allocation decisions.]
5. Review and Reporting Schedule: [Annual review; public progress report at each AGM.]

Conclusion, Corporate Lawyers South Korea: Next Steps for Boards and GCs

The 2026 Commercial Act amendments demand prompt, structured action from every listed company in South Korea. The core obligations can be distilled into three priorities:

• Treasury stock: Inventory holdings, identify cancellation candidates and file Holding & Disposal Plans for any shares retained under a statutory exception.
• Board composition: Verify independent-director eligibility under the tightened criteria and update nomination-committee processes.
• Disclosure: Prepare and file corporate value-up plans, establish English-disclosure workflows (for applicable KOSPI companies) and update internal sign-off controls ahead of the 30 December 2026 deadline.

Boards that move early will be best positioned to manage regulatory expectations, reassure investors and avoid the reputational and financial costs of non-compliance. For specialist guidance on implementing the reforms, consult qualified corporate lawyers with deep expertise in South Korean corporate governance and regulatory compliance.
