SpacDeskS-4 Registration Statement
The SEC registration statement filed when a SPAC issues new securities to the target company's shareholders as part of the business combination, serving as both a prospectus for the new shares and a proxy statement for the shareholder vote.
The S-4 (or S-4/A for amendments) is the cornerstone regulatory filing in most SPAC business combinations. When the SPAC merges with the target and issues new shares to the target's existing shareholders, those shares must be registered under the Securities Act of 1933. The S-4 accomplishes this registration while simultaneously serving as a proxy statement to solicit the SPAC shareholder vote on the transaction.
An S-4 filing for a SPAC deal typically contains:
Target company financials
Audited financial statements of the target, often covering 2–3 fiscal years. These are the first public financial disclosures for the target if it was previously private.
Pro forma financials
Combined financial statements showing what the merged entity would look like, including adjustments for trust redemptions, PIPE proceeds, and transaction expenses.
Deal terms
The merger agreement, including per-share consideration, earnout structures, lockup terms, and any side agreements.
Risk factors and projections
Detailed risk disclosures and, in some cases, financial projections provided by the target (subject to enhanced SEC scrutiny since 2024).
The SEC reviews the S-4 and may issue one or more rounds of comment letters requiring revisions before declaring the registration effective. This review process typically takes 30–90 days and is often the longest phase of the de-SPAC timeline.
Some deals use a DEFM14A (proxy statement) instead of an S-4 when no new securities are being registered — for example, when the deal is structured as an all-cash acquisition funded entirely from the trust.
SpacDesk processes S-4 and S-4/A filings to extract deal terms, financial data, and risk factors, with each extracted value linked to its source paragraph in the filing.
