De-SPAC due diligence: what changes when a SPAC is the buyer

A traditional acquisition ends with a private agreement between buyer and seller. A de-SPAC ends with a public company, a registration statement and a shareholder vote. That difference shapes everything about how diligence is done and how the data room is built.

This guide covers what is distinctive about de-SPAC diligence and how to set up a room that supports it. For the wider context of public listings, see our IPO and capital markets hub and our guide to investing in an IPO.

What is a de-SPAC transaction?

A SPAC is a shell company that raises money in its own initial public offering, holds the proceeds in a trust account and then looks for a private operating company to acquire. The de-SPAC is that acquisition: the SPAC merges with the target, and the target becomes a listed company without running its own traditional IPO.

Three features of the structure drive the diligence process:

• A deadline. The SPAC’s charter sets a period to complete a business combination, commonly 18 to 24 months, and stock exchange rules impose an outer limit. If the SPAC misses its deadline, it must generally return the trust money unless shareholders approve an extension.
• Redemptions. SPAC shareholders can redeem their shares for cash from the trust at the vote. High redemptions mean the deal often relies on additional financing, frequently a PIPE (private investment in public equity).
• Public disclosure. The combination usually requires a registration statement on Form S-4 or F-4, or a proxy statement, reviewed by the SEC before shareholders vote.

How is de-SPAC diligence different from a normal acquisition?

The shift in purpose is the key. In a private deal, a buyer can accept a risk and price it. In a de-SPAC, a material fact that is not properly disclosed can become a securities claim against those who signed the registration statement.

What did the SEC’s 2024 SPAC rules change?

In January 2024 the SEC adopted new rules for SPACs and de-SPAC transactions, effective July 1, 2024. For diligence, the most important changes are:

• The target is a co-registrant. When the SPAC files a registration statement for a de-SPAC, the target company must sign it too. The target and its signing officers and directors take on liability for its contents. Target management can no longer treat diligence as the buyer’s problem.
• No PSLRA safe harbor for projections. Forward-looking statements in de-SPAC filings no longer get the statutory safe harbor that protects many public company projections. Projections need a documented, reasonable basis.
• More disclosure on projections, conflicts, dilution and sponsor compensation. The bases and assumptions behind projections, the sponsor’s interests and potential sources of dilution must be described.
• A minimum dissemination period. Disclosure documents must generally reach shareholders at least 20 calendar days before the vote, where the law of the SPAC’s home jurisdiction allows. That fixes a minimum gap between final filing and the meeting.

For the data room, the practical effect is that two parties, not one, now need a complete evidence file behind every material statement.

How should a de-SPAC data room be structured?

A de-SPAC room serves more audiences than a typical sale room, and they need different things:

Two structural choices make this manageable.

Separate the evidence folders from the drafting folders. One area holds source documents: contracts, financials, permits, IP, litigation. Another holds the disclosure support file, which maps each material statement in the registration statement to the documents that support it. Counsel can then check coverage quickly, and the support file becomes part of the diligence defense record.

Treat PIPE access as a separate stage. PIPE investors receive material non-public information and are typically restricted from trading until it is public. Give them a dedicated, curated folder, record when each investor was given access, and keep the audit trail. A data room with group-level permissions and a reliable audit trail does this cleanly.

Which diligence workstreams matter most?

All the usual workstreams apply. Several carry extra weight in a de-SPAC:

• Financial reporting readiness. The target will become a public company immediately. Diligence must test not only past numbers but whether the finance team can produce timely, audited reporting and maintain internal controls.
• Projections. Test the assumptions, the track record of past forecasts and the sensitivity to key drivers. Expect investors and regulators to read them closely.
• Governance. Board composition, related-party transactions, and any arrangements with the sponsor need full disclosure.
• Regulatory and legal. Licences, litigation and compliance issues that a private company might live with become disclosure items.
• Capitalization. Options, warrants, earn-outs and convertible instruments affect dilution, which is now a required disclosure topic.

A vendor-prepared report can speed things up where the target has already been through a sale process; our guide to vendor due diligence reports explains how they work. Our due diligence hub covers the standard workstreams.

How to set up a de-SPAC data room

1. Map the timetable back from the deadline

   Work back from the SPAC's deadline through the shareholder vote, the 20-day dissemination period and expected SEC review to find the date diligence must be substantially complete.

2. Build the index around the filing

   Organize folders by workstream, and add a disclosure support area that will map registration statement sections to evidence.

3. Create audience groups

   Set up groups for the sponsor team, target team, auditors, counsel, financial adviser and each PIPE investor, with access defined before anyone is invited.

4. Run Q&A with approvals

   Route questions to target experts, require counsel approval before release, and keep the full log as part of the diligence record.

5. Control PIPE access

   Open the curated PIPE folder only when each investor has agreed to confidentiality and trading restrictions, and record the date.

6. Freeze and archive at signing and at closing

   Export a snapshot when the merger agreement is signed and again at closing, including documents, Q&A and audit trail.

What should you look for in a data room for a de-SPAC?

The deal moves fast and involves many parties, so the room has to be quick to administer and reliable as a record. Prioritize:

• Group permissions with document-level exceptions, for the many audiences above.
• Structured Q&A with routing and approval, so answers are consistent across sponsor, target and investors.
• A complete, exportable audit trail, which supports the diligence defense record.
• Dynamic watermarking and view-only controls for the projections and PIPE folders.
• Two-factor login enforced for every outside user; see our guide to two-factor authentication.
• Fast setup, because the SPAC clock is running from the moment a target is chosen.

Full-featured rooms such as Ellty, iDeals and Datasite cover these requirements; Ellty and Datasite also list AI features that can help reviewers work through large document sets under time pressure. The provider directory compares the controls of every room we track.

What happens to the room after closing?

After closing, the combined company files its post-closing Form 8-K and starts life as a public company. Keep the room’s archive under a retention period that reflects securities law limitation periods, and give both the sponsor’s counsel and the company access to the final export. Many companies then open a separate, long-running room for board and investor reporting; see our board communications page.
