What Is a Flip?
A Flip is a corporate restructuring in which a newly established U.S. company becomes the parent company, while the existing Korean company is converted into its operating subsidiary.
This is structurally different from simply establishing an additional entity in the United States.
| Category | Simple U.S. Entity Formation | Flip |
| Parent Structure | Korean company remains the parent | U.S. company becomes the parent |
| Shareholder Structure | Existing Korean shareholders remain unchanged | Existing shareholders exchange their holdings for shares in the U.S. parent |
| Primary Purpose | Local sales, contracting, payment operations | U.S. fundraising and reorganization of the group structure |
| Cost | Relatively low | Typically KRW 50 million to KRW 100 million or more |
After the Flip, the Korean company generally operates as an operating subsidiary of the U.S. parent company.
Mixing the two structures without a clear plan can create unnecessary cost and structural complexity.
Flip Process
A Flip generally proceeds in two major stages.
Step 1: Establish a U.S. Company
A Delaware C-Corporation is commonly used.
This stage itself can usually be completed relatively quickly.
Step 2: Convert the Ownership Structure Through a Share Exchange
The shares held by the shareholders of the existing Korean company are exchanged for shares in the newly established U.S. parent company.
Key items typically reviewed include:
| Item | Key Requirement |
| Company Valuation | Preparation of a fair market value assessment or DCF valuation report |
| Share Exchange Agreement | Agreement between shareholders of the Korean company and the U.S. company |
| Shareholder / Board Approvals | In practice, broad shareholder participation may be required for the U.S. parent to acquire 100% ownership |
| Foreign Exchange Reporting | Reporting to the Bank of Korea or designated foreign exchange bank under applicable foreign exchange regulations |
| Tax Treatment | Review and reporting of potential capital gains tax and other tax consequences |
Where institutional investors or government-backed funding are involved, obtaining the necessary consents may require significant time and negotiation.
Costs and Timeline
| Item | Estimated Cost |
| U.S. Company Formation and Local Legal Advice | Approximately USD 3,000–10,000 or more |
| Company Valuation Report | Approximately KRW 5 million–15 million |
| Korean Legal and Tax Advice | Approximately KRW 5 million–20 million or more |
| Total Estimated Cost | Often tens of millions of KRW or more, depending on company size and shareholder structure |
From initial structuring through completion of foreign exchange reporting, the overall process typically takes approximately three to six months.
A reverse Flip—restructuring from a U.S. parent back into a Korean parent structure—is generally more complicated and costly than the initial Flip.
For this reason, the decision to proceed with a Flip should be made cautiously.
How to Determine the Right Timing
One of the most difficult aspects of a Flip is determining when to proceed.
If the Flip is completed too early, the relationship with Korean investors may become more complicated.
If it is completed too late, the company may miss a U.S. fundraising opportunity.
A Flip May Be Appropriate Where:
- U.S. investors have begun discussing specific investment terms, at approximately the Term Sheet stage
- U.S.-based hiring becomes necessary and reaches a meaningful scale
- Consent from Korean institutional investors has been obtained or their influence is limited
It May Be Better to Delay a Flip Where:
- U.S. investors have only expressed preliminary interest and no concrete terms are being discussed
- Government-linked Korean venture capital funds are major shareholders
- The shareholder structure is complicated
- Existing investment agreements contain extensive prior-consent requirements
In practice, even after deciding to proceed with a Flip, obtaining shareholder consent and finalizing the restructuring may take several months.
Companies should therefore allow sufficient lead time—often at least one year for planning and stakeholder communication—where the shareholder structure is complex.
Prepare with DECENT Law Firm
A Flip is not an end in itself. It is a means of restructuring a company for a specific strategic objective, such as U.S. fundraising or market expansion.
The outcome can vary significantly depending on:
- the purpose of the restructuring;
- the timing;
- the existing shareholder structure;
- investor relationships; and
- the legal and tax structure selected.
The first step should therefore be to review the current shareholder structure and investor arrangements before deciding whether a Flip is appropriate.
