1. Global M&A | A Strategy for Entering the Global Market

The global M&A market contracted for a period after the pandemic, driven by surging asset prices, rising interest rates, and heightened geopolitical risk, but strategic activity has recently begun to reappear.
Notably, major companies in Asian countries, including Japan and Korea, are pursuing aggressive global M&A in order to expand meaningfully into developed-market economies.
CASE 1. SoftBank's Acquisition of Ampere
Japan's SoftBank acquired Ampere Computing of the United States, a designer of Arm-based data center CPUs, for roughly 6.5 billion dollars, signaling a clear strategy to secure a strong position in the AI infrastructure market.
CASE 2. Meiji Yasuda Life's Acquisition of a U.S. Insurer
Seeking to move beyond Japan's aging population and low interest rate environment, Meiji Yasuda, one of Japan's four major life insurers, acquired the insurance business division of Legal & General of the United States for roughly 2.3 billion dollars.
The transaction is expected to serve as a notable example of diversifying an insurer's revenue portfolio and securing a stable revenue source in overseas markets.
CASE 3. Korean Healthcare Companies' Overseas M&A Moves
Domestic pharmaceutical, bio, and medical device companies such as Company S and Company R are likewise pursuing acquisitions of global companies to secure technological capabilities, broaden their lineup of FDA-approved products, and enter the U.S. and European medical markets.
Through these moves, they aim to strengthen their competitiveness in AI software and reinforce their position in the North American medical market.
2. Global M&A | Core Process by Procedural Stage

Like a domestic corporate M&A, a global M&A generally moves through the following stages: advance preparation → bidding → due diligence → negotiation → closing of the acquisition → Post-Merger Integration.
Because the deal crosses borders, however, differences in language, systems, culture, and legal risk between the parties call for a more refined strategy.
Advance Preparation and Strategy Setting
- Clarifying the Purpose of the Acquisition: the goal, whether securing technology, entering a market, expanding the customer base, or strengthening a global brand, should be defined clearly
- Searching for the Target Company: identify potential targets and conduct a preliminary feasibility study with industry specialists and local advisers
- Designing the Acquisition Structure: select the most suitable structure, such as a stock acquisition, an asset acquisition, a merger, or a triangular merger
- Acquisition Financing Plan: prepare financing methods such as cash, share issuance, external borrowing, and joint acquisition, together with a foreign exchange risk hedging strategy
Letter of Intent (LOI) and Non-Disclosure Agreement (NDA)
A buyer generally submits an LOI that conveys genuine intent to the counterparty and enters into an NDA to secure access to information for due diligence.
Due Diligence and Negotiation
- Legal Due Diligence: contracts, litigation, intellectual property, and regulatory matters
- Financial Due Diligence: revenue structure, debt position, and risk analysis
- Tax Due Diligence: transfer pricing, foreign tax law, and whether tax treaties for the prevention of double taxation can be used
- Technical and Environmental Due Diligence: review of manufacturing processes, certifications, waste and emission standards, and related matters
Once the results of due diligence are reflected, the parties should specify the purchase price of the global M&A, the earn-out (conditional payment), the representations and warranties, and the indemnification clauses.
Along with any reporting or approval procedures required under local law, the report of overseas direct investment under the Korean Foreign Exchange Transactions Act must also be completed.
Closing of the Transaction and Post-Merger Integration (PMI)

Once a global M&A has closed, the Post-Merger Integration strategy carries significant weight, covering organizational integration, brand alignment, adjustment of the human resources and labor system, and system integration.
At the post-merger integration stage, operating policies generally need to reflect local labor law and personnel practices, and a review of transfer pricing taxation is also important.

3. Global M&A | Transaction Structure Types and Selection Strategy
1. Forward Merger VS Reverse Merger
- Forward Merger: the traditional merger structure in which the buyer becomes the surviving entity
- Reverse Merger: the target company becomes the surviving entity and the buyer ceases to exist
- can be advantageous for a backdoor listing or for preserving the continuity of the enterprise
2. Triangular Merger and Reverse Triangular Merger
- Forward Triangular Merger: the buyer's subsidiary absorbs the target company
- Reverse Triangular Merger: the subsidiary is absorbed into the target company, which survives
- the most commonly preferred structure in the United States, which can limit the liability of the acquiring company
3. Use of a SPAC (Special Purpose Acquisition Company)
- backdoor listings through SPACs are active in the United States
- the deadline for completing the business combination is 36 months, and if the merger fails, the listing does not proceed and the investment funds are returned
Measures to Address the Key Risks of Global M&A
Risk | Response Strategy |
Legal- permits and approvals, validity of contracts, and competition law violations | advice from a local law firm and advance regulatory review |
Tax- transfer pricing taxation and double taxation | review of the Korea-local tax treaty and tax due diligence |
Human Resources and Labor- labor law violations and disputes over the succession of employment | reflecting local labor practices and redrafting employment contracts |
Political/Judicial- exchange rate fluctuations, foreign exchange regulation, and distrust of the judiciary | foreign exchange risk hedging and a risk assessment report for high-risk countries |
Culture/Language- clashes in organizational culture and communication errors | appointment of a local PM and an integration strategy |
4. Global M&A | Strategies Companies Should Note

Allowing various merger structures used at the U.S. level, such as reverse triangular mergers, share exchanges, and asset transfers, to be used domestically as well can broaden M&A options when expanding overseas
subsidies for overseas expansion by industry and reform of systems to mitigate foreign investment risk in emerging markets
simpler procedures for foreign exchange transaction reporting and overseas direct investment reporting
forming cooperative channels with law firms and accounting firms that focus on major regions (the United States, the EU, ASEAN, and the Middle East)
selecting a global partner that can provide everything from preliminary feasibility review to PMI strategy in a single package
A global M&A can serve as a strategic means of building competitiveness in the global market.
For a global M&A to be completed successfully by both parties, a multilayered strategy generally helps, covering transaction structure design, advance risk review, an understanding of local systems, and PMI strategy.
