1. Share Cancellation | Structural Changes to Corporate Capital Policy and Practical Response Strategies

Share cancellation has now shifted from an option into the domain of a legal obligation.
On February 25, 2026, a partial amendment to the Commercial Act, the core of which is mandatory share cancellation, passed the plenary session of the National Assembly (hereinafter the "amended Commercial Act").
This amendment contains provisions that require companies, in principle, to cancel treasury shares they have acquired within a set period, and that strictly control the requirements for holding and disposing of such shares.
In particular, this amendment also establishes supplementary measures that adjust the burden on companies, reflecting the simplification of cancellation procedures for shares acquired for specific purposes and an extension of the grace period for industries subject to foreign ownership restrictions.
The following sets out the main contents of mandatory share cancellation, its effect on corporate practice, and the direction of future responses.
2. Share Cancellation | Key Contents of the Amended Commercial Act
The key contents of this amended Commercial Act are as follows.
Clarification of the Legal Status of Treasury Shares and Restrictions on Their Use
The amended Commercial Act expressly provides that treasury shares hold no rights whatsoever, including voting rights and dividend rights. This is regarded as a measure that effectively redefines treasury shares as a means of capital adjustment.
Accordingly, providing treasury shares as collateral, issuing bonds that use treasury shares as the object of exchange or redemption, and allocating new shares to treasury shares in the course of a merger or division are, in principle, restricted.
This is a regulatory change that requires a fundamental reexamination of the practice of using treasury shares as an asset-like instrument.
The Principle and Exceptions of the Share Cancellation Obligation
The core of the amended Commercial Act is the obligation to cancel shares within one year of acquisition. Accordingly, a company must cancel its treasury shares by a resolution of the board of directors within one year from the date of acquisition.
Only where a ground prescribed by law applies, however, may the shares be held or disposed of on an exceptional basis with the approval of the general meeting of shareholders.
Representative types of exceptional grounds are as follows.
In particular, where a company seeks to hold or dispose of shares beyond the cancellation deadline, it must obtain the approval of the general meeting of shareholders for a "treasury share holding and disposal plan" signed by all of the directors.
This plan must specifically include the purpose of the holding or disposal, the type and quantity of the shares concerned, the method of acquisition, the change in the ratio relative to the total issued shares, and the holding period and the expected time of disposal.
If a company violates this requirement, directors of a listed company and others may be subject to an administrative fine.
Application of the Same Regulation to Acquisition by Means of a Trust Agreement
The same cancellation obligation applies even where a listed company acquires treasury shares through a trust agreement.
The trustee may not dispose of the shares at its discretion during the term of the trust, and shares that are returned must likewise undergo cancellation or an approval procedure within one year.
This can be seen as incorporating every form of acquisition, including indirect acquisition, into the regulatory framework.
3. Share Cancellation | Effective Date and Transitional Measures
The amended Commercial Act takes effect immediately upon promulgation.
For treasury shares already held before the effective date, however, the following grace periods are recognized by type.
Companies must therefore carry out a precise classification of their held shares according to how each was acquired.
The Relationship with the Financial Investment Services and Capital Markets Act and Other Statutes
This amendment also raises the question of consistency with the framework of the Financial Investment Services and Capital Markets Act.
After the general meeting of shareholders approves an annual holding and disposal plan, individual disposals are permitted within that scope by a resolution of the board of directors, but a prior disclosure obligation applies in parallel.
There are also areas requiring practical adjustment, such as the relationship with the existing treasury share report system (disclosure twice a year) and the differences from the contents attached to the business report.
Beyond this, follow-up legislation and authoritative interpretations remain tasks that must be promptly settled, including the method of treating gains and losses on the disposal of treasury shares under the Corporate Tax Act, the tax treatment of treasury shares acquired through a merger, and the revision of the Enforcement Decree of the Financial Investment Services and Capital Markets Act.
4. Share Cancellation | Strategic Responses Companies Should Prepare

This mandatory share cancellation is interpreted as a signal of a shift in the direction of Korea's corporate governance framework.
Companies need the following strategic approaches.
② Review of the Articles of Incorporation
Use for management purposes requires a supporting provision in the articles of incorporation. Companies should consider amending the articles of incorporation so that they can encompass future purposes such as improving the financial structure, making strategic investments, and introducing new businesses.
③ Redesign of IR and Capital Allocation Policy
Mandatory share cancellation is regarded as a measure that institutionalizes the commitment to return capital to the market. Companies should therefore establish a capital allocation roadmap that integrates dividend policy, treasury share buyback and cancellation plans, and growth investment strategy, and they should actively communicate this to investors.
An Opportunity to Shift Capital Strategy
Combined with recent trends in amending the Commercial Act, such as the expansion of directors' duty of loyalty and the strengthening of the separate election of audit committee members, corporate governance is gradually being reorganized into a "shareholder-centered structure."
Share cancellation is therefore no longer a one-off decision and should be approached as a matter of redesigning the company's long-term strategy, IR policy, tax structure, and the framework of its articles of incorporation as a whole.
