1. Hostile M&A | Concept

Daeryun Law Firm explanation of the concept of a hostile M&A

A hostile M&A refers to the seizure of corporate control that occurs during the acquisition or merger of corporate ownership stakes without consultation with the existing major shareholders.

Unlike a friendly M&A, which is carried out by agreement between the buyer and the target company, a hostile M&A proceeds against the will of the acquired side.

Once virtually impossible because of the restriction on large-scale stock acquisition under Article 200 of the former Securities and Exchange Act, the hostile M&A emerged as a major issue in the stock market after that provision was abolished as of April 1, 1997.

Key Characteristics

A hostile M&A is distinguished from an ordinary M&A in that the merger and acquisition proceeds without the consent of the target company's management or major shareholders.

In this process, methods such as purchasing shares directly on the market or making a tender offer are used, and considerable costs may be incurred due to premium payments or legal responses.

In addition, because various defense strategies must be overcome, the acquisition procedure is complex, and the risk is high because the outcome is difficult to predict.

Nevertheless, it can improve management efficiency by replacing ineffective management, and it may also be expected to improve shareholder value.

It can also serve to strengthen competitiveness by promoting corporate restructuring.

2. Hostile M&A | Types

Summary of the three types of hostile M&A

The types of hostile M&A are broadly divided into three: tender offers, proxy contests, and market accumulation.

Tender Offer

A tender offer is a representative method used in a hostile M&A to secure management control without the consent of the target company.

This refers to a method of securing a stake outside the market by directly proposing to shareholders that the offeror will purchase their shares at a set price during a set period.

Proxy Contest

A proxy contest is a competition waged during a hostile M&A in which the acquiring side and the existing management seek to secure voting rights at the general shareholders' meeting.

The management of the target company seeks to defend its current management control, while the acquirer obtains proxies from shareholders and engages in a vote contest in order to succeed in the acquisition.

This competition to secure proxies serves as a core strategy in hostile mergers and acquisitions, and it is an important procedure that may bring significant changes to corporate governance.

Market Accumulation

In a hostile M&A, market accumulation is a strategy of securing a stake by continuously purchasing the shares of the target company on the open market.

This method is an attempt to acquire control without the consent of management, and it is one of the methods frequently used in a hostile M&A.

3. Hostile M&A | Defense Strategies

Daeryun Law Firm assistance regarding hostile M&A

Various defense strategies are used to respond to a hostile M&A.

Each strategy is aimed at protecting management control and effectively blocking the acquirer's approach.

Increasing the Burden of Acquisition Funds

This is a strategy of causing the attacking side to spend a large amount of acquisition funds for the M&A.

▷ A method of purchasing additional shares to raise the major shareholder's shareholding ratio

▷ A method of expanding the number of issued shares through a paid-in capital increase and allotting new shares to a friendly third party

▷ A method of issuing stock-related bonds, such as convertible bonds and bonds with warrants, that affect voting rights

▷ A method of mobilizing a white knight as a friendly party to sell treasury stock and the like

▷ A method of maintaining the share price through stable, profit-oriented management

Financial Strategy

To keep investors from selling their shares, the company should borrow funds and pay large-scale dividends at a high payout ratio.

In addition, the company can remove the purpose of the hostile M&A by separating key assets and business divisions into a separate legal entity or selling them to a third party.

It can also use methods such as raising its shareholding ratio through treasury stock purchases, and having existing shareholders acquire preferred stock and warrants and then convert them into common stock or the like.

Strategy Using the Articles of Incorporation

The company should arrange for directors to be elected at fewer than one-third of the total number of seats so as to delay the takeover of the board of directors.

It can also introduce a “golden parachute” strategy by newly establishing a provision under which, if the current management retires due to an M&A, a substantial amount in cash, stock options, and the like is paid in addition to severance pay, and the shares can be purchased at a fair price.

In addition to these, there are the use of cumulative voting, the shaping of public opinion, and litigation strategies.

4. Hostile M&A | Methods of Response

To respond effectively to a hostile M&A, you should first accurately assess the current situation with the assistance of an attorney.

To defend management control, you should promptly proceed with legal procedures, and work to secure support through active communication with shareholders.

In addition, you should closely monitor the status of tender offers and stock accumulation and, where necessary, devise a counter-response strategy.
