SPAC due diligence is more compressed than a traditional IPO diligence process — and it covers different ground. The target company is being diligenced simultaneously by the SPAC sponsor, PIPE investors, underwriters' counsel, and the sponsor's own advisors, often over a 6–10 week window. Preparation matters enormously.
Why SPAC Due Diligence Is Different from IPO Due Diligence
In a traditional IPO, due diligence is largely underwriter-driven and follows a standardized process. In a SPAC transaction, the SPAC sponsor leads initial diligence — but PIPE investors conduct their own parallel process, often more rigorously. The target company must simultaneously support two or more separate diligence workstreams, prepare the S-4 financial disclosures, and maintain normal operations. Companies that have not pre-organized their data room before sponsor outreach typically lose 3–4 weeks scrambling.
1. Financial Diligence
Financial diligence in a SPAC transaction focuses on audited and unaudited historical financials, financial projections (which are included in the S-4 and proxy in a way they are not in an IPO), and quality of earnings.
Financial Statements & Accounting
Audited financial statements — 2 full fiscal years minimum (PCAOB-registered auditor) Critical
Interim unaudited financials (most recent quarter) — reviewed by auditor Critical
Revenue recognition policy documentation — ASC 606 technical memo Critical
Quality of earnings (QoE) analysis — prepared by sponsor's financial advisor Critical
Working capital analysis — historical and normalized levels Critical
Capitalization table — fully-diluted, including all options, warrants, convertibles, SAFEs Critical
Deferred revenue schedule with aging and recognition timeline Important
Customer concentration analysis — revenue by top 10 customers Important
Backlog or contracted revenue schedule (if applicable) Important
Accounts receivable aging schedule and DSO analysis Important
Gross margin bridge — year over year with explanation of movements Important
EBITDA bridge — adjustments to arrive at Adjusted EBITDA (non-GAAP policy) Important
Management accounts — monthly for last 24 months Standard
Financial Projections
3–5 year financial model — Income statement, balance sheet, cash flow Critical
Model assumptions documented — key drivers, growth rates, margin expansion path Critical
Bridge from historical results to projected results — no hockey stick without explanation Critical
Sensitivity analysis — key downside scenarios and their financial impact Critical
Capital requirements — when does the company need additional capital beyond SPAC proceeds? Critical
Management's history of meeting financial projections — comparison of prior forecasts to actuals Important
Industry benchmark comparisons — how do margins compare to public peers? Important
2. Legal & Corporate Diligence
Legal diligence in a SPAC is conducted by both the SPAC's counsel and the target's counsel. The legal team is simultaneously building the diligence file and drafting the S-4 — which means legal issues discovered late have direct S-4 drafting implications.
Corporate Records & Governance
Certificate of Incorporation / Articles and all amendments Critical
Bylaws / Operating Agreement — current version Critical
Board minutes — last 3 years (look for undisclosed material events) Critical
Stockholder/equity holder agreements — voting, drag-along, registration rights Critical
Cap table — fully-diluted with all option grants, exercise prices, and vesting schedules Critical
Organizational chart — all subsidiaries, JVs, and foreign entities Critical
State / foreign qualifications — all jurisdictions where company does business Important
Prior financings — all equity and debt rounds with complete documentation Important
Material Contracts
Top 10 customer contracts — including renewal, termination, and exclusivity provisions Critical
Top 10 supplier / vendor contracts — critical dependencies and termination rights Critical
All contracts with change-of-control provisions — does the SPAC merger trigger any? Critical
All contracts with assignment restrictions — same change-of-control trigger analysis Critical
Key employment agreements — CEO, CFO, and C-suite (including non-compete, IP assignment) Critical
Debt instruments — credit facilities, notes, convertibles — all covenants and triggers Critical
Real estate leases — material locations with remaining terms Important
License agreements — technology in-licenses and out-licenses Important
Government contracts and grants — compliance requirements and termination provisions Important
Intellectual Property
IP ownership confirmations — all key IP owned by the company, not individuals Critical
Patent portfolio — issued patents and pending applications by jurisdiction Important
Trademark registrations — by brand and jurisdiction Important
Trade secret protection protocols — NDA program and access controls Important
Open source usage audit — any GPL/LGPL code in the product? Important
IP assignments from founders and early employees Critical
Litigation & Regulatory
All pending and threatened litigation — with counsel's assessment of materiality Critical
Regulatory correspondence — any open investigations, inquiries, or consent decrees Critical
Environmental compliance — material locations and any prior violations Standard
Employment claims — discrimination, wage/hour, WARN Act matters Important
Privacy and data security — data breach history, GDPR/CCPA compliance posture Important
3. Commercial & Operational Diligence
PIPE investors in particular conduct thorough commercial diligence — they are making an investment decision with full information and require confidence in the business model and competitive position before committing capital.
Business Model & Market
Market size analysis with bottom-up support — TAM/SAM/SOM Critical
Competitive landscape — direct and indirect competitors, positioning, win/loss data Critical
Product roadmap — 12–24 month development plan with investment requirements Important
Customer cohort analysis — retention, expansion, and churn by cohort vintage Critical
Unit economics — CAC, LTV, payback period with supporting data Critical
Sales pipeline and go-to-market strategy documentation Important
Reference calls — 3–5 customers interviewed by PIPE investors or sponsor advisors Critical
Management & Team
CEO and CFO backgrounds — including prior public company experience Critical
Full management team bios — prior relevant experience Critical
Key person risk assessment — who leaves, what breaks? Critical
Retention plan — what equity and cash retention arrangements are in place? Important
Board composition plan — who fills the independent director seats post-close? Critical
Organizational gaps — what roles need to be hired to operate as a public company? Important
4. Public Company Readiness Diligence
Unlike an IPO where the company has 12–18 months to prepare for public company obligations, a de-SPAC target often goes from private company to public company in 4–6 months. Sponsor and PIPE investors diligence readiness gaps specifically because they remain exposed to operating failures post-close.
Finance & Reporting Infrastructure
Financial reporting close process — can you close in 25 business days post-quarter? Critical
CFO background — public company CFO experience strongly preferred Critical
Controller background — public company or Big Four audited company experience Critical
ERP system — can it support SEC reporting, XBRL tagging, multi-entity consolidation? Critical
Accounting advisory firm engaged — for SOX readiness, ASC 606, and close process Critical
Audit committee charter and membership plan Important
D&O insurance broker engaged and preliminary coverage in place Critical
Internal Controls
SOX readiness assessment — which controls need to be built? Critical
Material weaknesses or significant deficiencies — documented and remediation plan in place Critical
IT general controls — access management, change management, operations Important
Financial reporting controls — period-end close controls, reconciliation procedures Critical
Financial Due Diligence Areas
The SPAC's financial due diligence on a target company is broadly similar to M&A due diligence, but with additional focus areas driven by the de-SPAC regulatory framework:
- Quality of earnings (QofE) analysis: An independent QofE report — typically produced by an accounting advisory or transaction services firm — adjusts reported EBITDA for non-recurring items, normalizing adjustments, and accounting policy differences. The QofE is a foundation for the financial projections that will be disclosed in the SPAC proxy statement.
- Revenue recognition and accounting standards compliance: The target company's financial statements must be GAAP-compliant and audited. Non-compliant accounting or material weaknesses must be identified and remediated before the de-SPAC proxy is filed.
- Projection analysis: Unlike traditional IPOs, SPAC transactions can include forward-looking financial projections in the proxy statement. The SPAC's financial advisors must have a reasonable basis for the projections, which means validating the assumptions against historical performance and industry benchmarks.
- Working capital analysis: Confirming that the combined company will have adequate working capital post-close, especially given the uncertainty of SPAC share redemptions that could reduce available cash.
Regulatory and Legal Due Diligence
The de-SPAC transaction is a merger that must be approved by the target company's shareholders (if required) and may require regulatory approvals:
- HSR antitrust review: If the target company has revenues above the HSR thresholds, a Hart-Scott-Rodino filing may be required before the merger can close. Obtain HSR counsel's view early in the process.
- SEC review of proxy statement: The SPAC files a proxy statement (Form DEFM14A) with the SEC to obtain shareholder approval of the business combination. The SEC reviews this document with at least as much scrutiny as an S-1 — sometimes more, given the inclusion of financial projections. Allow 2–3 rounds of SEC comments and 4–6 months for the full review process.
- State gaming, financial services, or other regulatory approvals: If the target company operates in a regulated industry, industry-specific regulatory approvals may be required before the merger closes.
