1. Changes in regulatory environment for corporate reorganization
Corporate reorganization refers to redesigning a company's organizational structure and management system through mergers, divisions, business transfers, and governance reorganization.
This is an important decision that goes beyond structural changes and directly affects shareholder rights, governance, and corporate value.

After the 2025 amendment to the Commercial Act strengthened the duty of loyalty of directors, the Ministry of Justice in February 2026 announced the “Guidelines for the Code of Conduct for Directors during Corporate Reorganization.”
Although these guidelines are not legally binding regulations,Functions as a kind of soft norm that presents specific standards on how directors should fulfill their duty of loyalty.do.
The problem is that there has recently been a case where the financial supervisory authorities requested corrections to the securities report and major facts report based on compliance with the guidelines during the actual corporate reorganization process.
This means that the guidelines are more likely to function as regulatory standards rather than just recommendations.
Furthermore, it is difficult to rule out the possibility that it may become a de facto obligation if it is reflected in the future disclosure form preparation standards.
Core structure of the Ministry of Justice guidelines
The guidelines areIf there is a conflict of interest between directors, controlling shareholders, management and the company, or between controlling shareholders and general shareholders, measures to ensure fairness must be taken and this must be fully explained to shareholders.do.
The key is not simply to proceed with the transaction, but to be able to prove that the process and results are objectively fair.
For this purpose, the following measures are highlighted:
First, composition of an independent special committeeno see. It is required to form a committee centered on outside directors who are independent from the controlling shareholders and to grant substantive review authority from the early stages of the transaction.
If the board reaches a different conclusion, the reasons must be clearly recorded.
Second, independent review by external expertsno see. A multi-layered review structure is needed, including reviewing the legality and fairness of the transaction through legal advice and analyzing valuation and market conditions through financial advice.
Third, providing sufficient information to shareholdersno see. Beyond formal disclosure, the background of the transaction, the alternative review process, whether there is a conflict of interest, and measures to ensure fairness must be explained at a level that shareholders can understand.
2. Strengthened behavioral standards for each transaction type when reorganizing a corporate organization
Let’s take a look at the standards that have been strengthened by the Director’s Code of Conduct Guidelines during corporate reorganization.
Merger between affiliates
Since a merger between affiliates is structured so that the same controlling shareholder influences both companies, there is a possibility that the merger price will be set in favor of a specific shareholder.
Accordingly, an independent special committee must be formed for each company to separately review the necessity, timing, conditions, and structure of the merger, and objectivity must be secured through the evaluation of external experts and multiple consultations on the merger price.
In addition, during the disclosure, the necessity of the merger, the impact on shareholder value, the basis for calculating the merger value, the structure of interests, and changes in governance structure after the merger must be specifically stated.
Closed enterprise (delisting) transaction
Closed corporate transactions conducted through tender offers and stock exchanges are subject to more stringent standards in that there is a high possibility of information asymmetry and pressure on general shareholders.
In this case, opinions on the tender offer must be reviewed through a special committee and the fairness of the price must be verified through an external expert.
In particular, when tender offers and stock exchanges occur sequentially, it is important to ensure fairness between prices, and a structure that provides autonomous selection opportunities to general shareholders is required.
Key practical issues seen in disclosure correction cases
Looking at recent cases of correction requests from financial supervisory authorities, we can see that compliance with guidelines serves as a key review factor for disclosure.
In particular, the following points were required to be intensively supplemented:
Regarding the special committee, the timing of establishment, composition, authority, discussion content, external consultation results, final opinion, and whether or not it is reflected by the board of directors must be described in detail.
External experts had to be explained in detail, including the reason for selection, independence, work performed, review results, valuation methodology, and basis for applying discount rates, as well as actual analysis content.
In addition, in terms of providing information to shareholders, it was required to explain the alternative review process, conflict of interest structure, general shareholder protection plan, and communication plan.
This is an example showing that disclosure serves as a means of proving the fairness and rationality of decision-making.
3. Response strategy in case of corporate reorganization

This regulatory change isThe core risk of corporate reorganization is moving from ‘the transaction itself’ to ‘legitimacy of the procedure’.It shows.
Although the guidelines do not have legal force, they are actually used as a basis for judgment by supervisory agencies, and there is a possibility that they may be institutionalized in the future.
Therefore, companies should consider the following from the early stages of planning reorganization.
2. Recognizing the disclosure strategy as a means of responding to regulations
3. Providing information at an understandable level from a shareholder's perspective
Ultimately, corporate reorganization is no longer a matter that can be completed solely through internal management decisions, but is transitioning into the area of ‘explainable decision-making’ that requires persuading external stakeholders and supervisory agencies.
