The SPAC transaction process has two phases from the target company's perspective: everything before the deal announcement (preparing to be an attractive SPAC target), and everything after the announcement (executing the transaction and becoming a public company). This guide covers both — with practical detail on the workstreams, timelines, and decision points that determine whether the transaction closes successfully.
Sponsor Outreach, Evaluation & Readiness
Before a SPAC deal can be announced, the target company must both attract qualified SPAC sponsors and be genuinely ready to execute the transaction. These two requirements are more interrelated than many companies realize — the best SPAC sponsors are highly selective, and they conduct significant diligence before signing a letter of intent.
How SPAC Sponsors Find Target Companies
SPAC sponsors typically operate through two channels: direct outreach to target companies they have identified through industry knowledge, and introductions through investment bankers who serve both sides of SPAC transactions. Companies that are considering the SPAC path should proactively engage M&A advisors or investment bankers who have active relationships with reputable SPAC sponsors in their sector.
When evaluating a sponsor, the quality of the sponsor matters as much as the economic terms. A strong sponsor brings genuine industry expertise, a network of institutional investors who can anchor the PIPE, and operational experience that improves the company's post-close governance and strategy. A weak sponsor — motivated primarily to complete any deal before the SPAC trust deadline — creates misaligned incentives from the start.
Evaluating Potential Sponsors
Target Company Readiness
The Readiness Misconception
Many companies pursue SPAC transactions believing the process allows them to skip or compress the financial readiness work required for a traditional IPO. It does not. The S-4 requires audited GAAP financial statements from a PCAOB firm, the same governance restructuring, the same legal clean-up, and substantially the same disclosures as an S-1. The only genuine timeline compression is in the post-announcement execution — not in the readiness preparation that must precede any public company transaction.
Letter of Intent, Exclusivity & Deal Announcement
The letter of intent (LOI) marks the formal beginning of the de-SPAC transaction. It is a non-binding agreement that sets out the key economic terms — valuation, deal structure, PIPE commitment, and exclusivity period — while definitive documentation is negotiated. The moment the LOI is signed, the work begins in earnest.
Key LOI Terms for Target Companies
The LOI is non-binding, but the economic terms established at this stage typically persist through closing. Management should review the LOI carefully before signing — with experienced M&A counsel — as the implied economics may be more dilutive than they appear at first glance.

Phase 2 Key Deliverables
⚠️ Common Phase 2 Mistakes
- Not modeling the fully diluted cap table including all promote, warrants, PIPE dilution, and earnout shares before signing the LOI — the headline valuation is almost always more favorable than the diluted economics
- Signing with a sponsor whose PIPE network is weak — a sponsor who cannot raise quality PIPE is a significant execution risk
- Inadequate legal review of the definitive merger agreement before signing — especially change-of-control provisions in material contracts
- Underestimating the employee and stakeholder communication demands that begin the moment the deal is announced
Due Diligence & S-4 Registration Statement Drafting
Due diligence and S-4 drafting run concurrently — the most resource-intensive phase of the de-SPAC transaction. The target company's management team is simultaneously responding to diligence requests from the SPAC's counsel and investors, providing information for the S-4 registration statement, preparing audited financial statements (if not already complete), and restructuring governance for public company requirements.
The S-4 Registration Statement
The S-4 is the de-SPAC equivalent of the S-1 registration statement. It contains the proxy materials sent to SPAC shareholders to vote on the business combination, and includes comprehensive disclosure about the target company — including its business, risk factors, audited financial statements, MD&A, and pro forma financial information. The SEC reviews the S-4 with the same rigor it applies to S-1 filings.

Financial Projections in the S-4 — The Changed Landscape Post-2024
Historically, one of the key advantages of the SPAC path over a traditional IPO was the ability to include management's financial projections in the S-4 proxy materials, protected by the PSLRA safe harbor for forward-looking statements. The SEC's 2024 rule changes eliminated this safe harbor for de-SPAC transactions. Projections in SPAC S-4 filings now carry the same legal liability as projections in a traditional IPO S-1. Companies considering the SPAC path should review the legal implications of any projections with experienced securities counsel before committing to include them in the S-4.
Phase 3 Key Deliverables
PIPE Financing, S-4 Filing & SEC Review
Phase 4 has two parallel tracks: the PIPE marketing process (raising additional capital from institutional investors) and the SEC review of the S-4 registration statement (2–3 rounds of comment letters). Both tracks must complete before the shareholder vote can be scheduled — and delays in either can push back the close date.
The PIPE — Why It Matters and How It Works
A PIPE (Private Investment in Public Equity) is a private placement of shares in the combined entity sold to institutional investors concurrently with the de-SPAC transaction. PIPEs serve two purposes: they provide additional capital for the combined company (particularly important when redemption rates are high), and they provide third-party validation of the deal valuation by institutional investors who have conducted their own diligence.
PIPE Economics
PIPE investors typically buy shares at the deal price (the same per-share price as the SPAC trust NAV or a slight premium). PIPE shares are registered for resale in the S-4, giving PIPE investors a path to liquidity post-close. PIPE investors receive no promote or warrants — they are pure equity investors at the deal valuation.
PIPE Investor Quality
High-quality PIPE investors — long-only funds, fundamental buyers with multi-year investment horizons — signal genuine institutional confidence in the deal. Weak PIPE investors who intend to sell immediately post-close create post-close stock overhang. The composition of the PIPE is closely watched by markets as a proxy for deal quality.
Redemption & PIPE Interaction
In the post-2021 environment, high redemption rates have made the PIPE a critical capital source. A company expecting $300M from the SPAC trust but facing 80% redemptions receives only $60M from trust — making the PIPE the primary capital raise. If the PIPE is too small to compensate for redemptions, the combined company may close with significantly less capital than planned.
Minimum Cash Condition
Definitive merger agreements typically include a "minimum cash condition" — a threshold of combined trust + PIPE proceeds below which the target has the right to terminate the deal. This is a critical negotiation point: setting the minimum cash condition too low can leave the company undercapitalized; too high creates termination risk if redemptions are severe.
Modeling Redemption Scenarios
Every target company in a SPAC transaction should model their capital position across a range of redemption scenarios before closing. The following illustrative model shows the impact of varying redemption rates on a $300M SPAC trust with a $100M PIPE.

Phase 4 Key Deliverables
Shareholder Vote, Redemption Window & De-SPAC Closing
The shareholder vote is the penultimate step — SPAC public shareholders vote to approve the business combination, and simultaneously have the right to redeem their shares for the trust value regardless of how they vote. The period between S-4 effectiveness and the shareholder vote is typically 20–30 calendar days as required by SEC proxy rules.
The Redemption Mechanics
Every SPAC public shareholder has the contractual right to redeem their shares for approximately $10.00 plus accrued interest from the trust account — regardless of whether they vote for or against the deal. This right can be exercised up to two business days before the shareholder vote. The actual redemption rate is not known until the redemption deadline passes — creating significant uncertainty about the final capital structure until the last moment before close.

Closing Mechanics
What Happens If the Minimum Cash Condition Is Not Met
If redemptions are so severe that the combined trust + PIPE proceeds fall below the minimum cash condition, the target company typically has three options: waive the minimum cash condition and proceed with less capital than planned; attempt to raise additional PIPE capital on an emergency basis (difficult and expensive); or terminate the merger agreement and walk away from the deal. In the current high-redemption environment, companies should model the "walk away" scenario carefully and ensure the minimum cash condition is set at a level that actually protects their ability to operate post-close.
First 12 Months as a Newly Public Company
The de-SPAC closing is not the end of the process — it is the beginning of public company obligations that run on a strict regulatory calendar from the moment the merger closes. SPAC-path companies must meet the same SEC reporting requirements, SOX compliance obligations, and investor relations demands as traditionally IPO'd companies. There are no accommodations or grace periods from the SPAC structure.

The Post-SPAC Investor Base Challenge
One of the most significant post-close challenges for SPAC-path companies is that the initial shareholder base is dominated by SPAC arbitrage investors who redeemed or are looking to exit quickly — not the long-term institutional investors that form the foundation of a stable public company shareholder base. Building a quality institutional investor base post-close requires an active, sustained non-deal roadshow program and consistent delivery on financial commitments. Companies that miss guidance in their first or second quarter post-SPAC face severely disproportionate stock price reactions.
⚠️ Post-Close Risks Unique to SPAC-Path Companies
- The "Super 8-K" filing must be completed within 4 business days of close — this requires substantial preparation before the vote, not after
- Post-SPAC companies frequently face securities class action litigation if the stock trades below the deal price — projections disclosed in the S-4 are a primary basis for these claims
- Warrant accounting can be complex — depending on terms, SPAC warrants may require liability classification under ASC 815, creating earnings volatility that confuses investors
- The sponsor promote creates a large block of low-cost shares that can depress trading if released to market — understand the vesting and lock-up schedule before close
SPAC Process in Practice
DraftKings — LOI to Close in 45 Days (2020)
DraftKings' SPAC merger with Diamond Eagle Acquisition Corp set the speed record for a major de-SPAC transaction. The LOI was signed in January 2020, the merger agreement in April 2020, and the transaction closed on April 23, 2020 — approximately 45 days from public announcement to close. This speed was enabled by several factors: DraftKings was genuinely IPO-ready (it had clean GAAP financials, a functioning finance team, and a PCAOB-audited history), the transaction structure was straightforward (no complex earnouts or contingent consideration), and the regulatory approval path was clear (no HSR issues, no industry-specific regulatory approvals required). The DraftKings timeline is frequently cited by SPAC sponsors as the aspirational benchmark — but advisors caution that it required exceptional preparation by the target and should not be used as a planning assumption for companies that have not done the pre-SPAC readiness work.
Grab — 17 Months, Largest SPAC Ever at $40 Billion (2021)
Grab Holdings' merger with Altimeter Growth Corp took 17 months from announcement to close — among the longest major SPAC transactions — and valued Grab at approximately $40 billion, making it the largest de-SPAC transaction in history. The complexity driving the extended timeline: Grab operated in eight Southeast Asian countries, each with different regulatory approval requirements; the company's financial statements required significant work to become US GAAP compliant; the SEC's review of the S-4 proxy statement was extensive, with multiple comment rounds focused on Grab's financial projections and the principal/agent determination for its ride-sharing and food delivery businesses; and the PIPE raise required significant marketing to Asian institutional investors unfamiliar with the SPAC structure. The Grab case illustrates that internationally complex businesses should plan for 12–18 months from LOI to close, not 3–6 months.
Nikola — Rushed Timeline, Critical Diligence Omissions (2020)
Nikola's SPAC merger closed in June 2020 — approximately 5 months from LOI to close, which was fast but not record-breaking. The speed came at a cost: the due diligence process did not adequately verify the technology claims that founder Trevor Milton was making publicly. A more thorough technical diligence process — including independent engineering assessments of the claimed hydrogen fuel cell technology and the battery-electric truck platform — would have revealed that the technology was not as developed as claimed. By the time the Hindenburg Research report surfaced these issues in September 2020, the merger had already closed and shares had been distributed to SPAC investors, leaving no mechanism to unwind the transaction. The Nikola case is the primary reason that SPAC due diligence standards have tightened significantly since 2020, with advisors now recommending independent technical experts for any SPAC target making technology claims.
