What it means
When one company buys another and pays partly or fully in its own shares, those shares are being offered to the target's shareholders. In the United States, that offer must normally be registered.
Form F-4 is the registration statement for these deals when the acquirer is a foreign private issuer. The document works like a combined prospectus and proxy statement.
It tells target shareholders what they will receive, explains the background and reasons for the deal, and includes information about both companies. It often includes pro forma financial information, which shows how the combined business might have looked had the deal taken place earlier.
The exchange ratio is at the heart of the transaction. It states how many acquirer shares each target share will convert into, and it may be fixed or may float with the share price.
Shareholders can then work out the value of the offer by multiplying the ratio by the acquirer's price. The SEC staff review the filing, and companies often file several amendments before it is declared effective.
After that, the document is sent to shareholders, who vote or decide whether to tender their shares. Timetables are set by the deal documents and the rules.
For finance teams, F-4 projects are intensive. Auditors, lawyers and bankers must agree on the numbers, the pro forma data and the risk factors.
An inconsistency can delay the deal, and a misstatement can lead to claims. Investors should read the sections on the background and the risk factors.
They show how the price was reached and what could go wrong after the combination. Reading them side by side shows how different the two companies are and how hard it may be to merge them.
In practice
Real-world examples.
Example
A foreign bank agrees to buy a smaller US lender using its own shares. It files a Form F-4 to register the new shares that target shareholders will receive. The bank's lawyers also prepare the documents for the target's shareholder meeting.
Example
A pair of overseas software companies merge in a share exchange. The registration statement includes pro forma figures for the combined group. Investors see the likely size of the new company in terms of revenue and debt.
Example
A merger arbitrage analyst reads the filing for an upcoming deal. She calculates the value of the exchange ratio and compares it with the target's share price. The gap, called the spread, shows how confident the market is that the deal will close.
Formula
Calculation
Number of new shares = Target shares outstanding x Exchange ratio
Worked example: An acquirer will issue 0.5 of its shares for each target share, and the target has 20,000,000 shares outstanding.
New shares to be issued = 20,000,000 x 0.5 = 10,000,000
If the acquirer's shares trade at $30, the offer is worth 0.5 x $30 = $15 per target share, and the total value is 10,000,000 x $30 = $300,000,000.Case study
Seen in the real world.
Harlow Pharma is a fictional foreign drug company used as an illustrative example. It agrees to buy a smaller research firm, paying 0.5 of its own shares for each share of the target.
Lawyers prepare a Form F-4 describing the deal. They respond to comments from the SEC staff, update the pro forma statements and file amendments until the filing is cleared. The deal team keeps a log of every comment and response.
Target shareholders receive the final document and vote to approve the merger. The case shows that a share-based deal needs a full disclosure package, because the target's owners are becoming investors in the acquirer. They need the same quality of information as any new shareholder. The company's counsel adds that incomplete disclosure in a share-based deal can lead to claims long after the merger has closed.
Watch out
Common mistakes.
- Reading only the headline value. The value changes as the acquirer's share price moves, unless the ratio is adjusted. A rise or fall in that price changes what target holders really receive.
- Ignoring the pro forma figures. They are illustrations, not forecasts, and rely on assumptions. Readers should check those assumptions.
- Assuming the form is used for all foreign deals. It applies to certain securities issued in business combinations and exchange offers. Other deals use other forms.
Questions

What is an exchange ratio?
It is the number of acquirer shares that each target share converts into. It may be fixed or may float.
Who reviews the filing?
The SEC staff review it, and the company often files several amendments before it is declared effective. Each amendment responds to staff comments.
How is it different from Form F-1?
