SEC Form F-4 is the registration statement used by foreign private issuers to register securities issued in connection with mergers, acquisitions, and exchange offers involving a foreign company. It is the international equivalent of Form S-4, which domestic U.S. companies use for the same purpose. Any foreign company that wants to offer its securities to U.S. shareholders as part of a business combination transaction must file Form F-4 with the SEC before the deal can close.
Think of it as the disclosure package a non-U.S. acquirer must hand to American shareholders before asking them to vote on or accept a deal.
You file a Form F-4 when a foreign private issuer issues securities in a U.S.-registered transaction that falls into one of these categories: a merger or acquisition in which shareholders must vote on the deal, an exchange offer in which the foreign company offers its own securities in exchange for those of a target, or a combination where shareholders receive securities in a reorganization or reclassification.
It is most commonly used in cross-border mergers and acquisitions involving both a foreign company and a U.S. target or U.S. shareholders. Special Purpose Acquisition Companies involving foreign private issuers also use Form F-4 for the de-SPAC business combination transaction.
The Form F-4 pulls from both the S-1 framework for new registrants and Form 20-F, the annual report form for foreign private issuers. The content requirements depend on whether the filing company qualifies as an F-3 eligible issuer, meaning it has been a reporting company for at least 12 months with a strong compliance history.
Every Form F-4 must include:
| Form F-4 | Form S-4 | |
|---|---|---|
| Who files it | Foreign private issuers | Domestic U.S. companies |
| Accounting standard | IFRS accepted; U.S. GAAP reconciliation may apply | U.S. GAAP required |
| Annual report reference | Form 20-F disclosure framework | Form 10-K disclosure framework |
| Transactions covered | Cross-border M&A, exchange offers, SPAC de-SPAC transactions involving foreign issuers | Domestic mergers, acquisitions, exchange offers |
If a U.S. domestic company is the acquirer and the target is a foreign private issuer, the domestic company files Form S-4, not F-4. The determining factor is the legal domicile and issuer status of the company registering the new securities, not the nationality of the target.
Companies must file Form F-4 before any solicitation of shareholder votes, typically at least 20 business days before the shareholder meeting. Financial statements in the form go stale according to the same rules that apply to Form 20-F filings. F-3 eligible issuers can incorporate updated financials by reference rather than filing a full post-effective amendment. First-time registrants cannot use that shortcut.
