Special-Purpose Acquisition Company

A special-purpose acquisition company (or SPAC) is a blank-check company created specifically to acquire a private operating company and take it public. A SPAC raises capital through a traditional IPO without a specific business plan, holds the proceeds in trust, and then uses them to acquire and merge with a private company. The private company’s shareholders become shareholders of the combined public entity. SPACs became a popular alternative to traditional IPOs in the 2010s and 2020s, though they have also attracted regulatory scrutiny and criticism.

How a SPAC works

Formation and IPO. Investors (often experienced entrepreneurs or PE sponsors) form a SPAC and go through an IPO. The SPAC raises capital (typically $100 million to $5 billion) by selling shares to public investors at, say, $10 per share.

Trust account. The proceeds are deposited in a trust account and can only be used to acquire a company or are returned to shareholders if the SPAC fails to find a target within a specified timeframe (typically 24 months, extendable to 36 months).

Target search. The SPAC’s sponsors (the founders and board) spend 12–24 months searching for a private operating company to acquire. They seek targets that are:

• In high-growth sectors (technology, healthcare, consumer)
• Valued at $500 million to $2+ billion
• Willing to merge with the SPAC to gain public access
• Founded by entrepreneurs who want to monetize their stakes

Acquisition and de-SPAC merger. Once a target is identified, the SPAC and target negotiate and agree on a merger (called a de-SPAC transaction). The transaction is announced, and shareholders vote on it.

Redemption period. During the period after announcement, SPAC shareholders can choose to redeem their shares for cash (their original $10 investment plus interest from the trust account). Those who want to continue with the merger keep their shares.

Closing and public trading. Once sufficient shareholders remain and conditions are met, the transaction closes. The private company becomes a public company under the SPAC’s ticker symbol (often relabeled with a new name).

Capital infusion. Before closing, the SPAC often raises additional capital from investors (a PIPE, or private investment in public equity) to fund the deal and provide growth capital to the new public company.

Advantages of SPACs

Speed. A SPAC-based public listing can be completed in 12–18 months, faster than a traditional IPO.

Capital raise. Unlike a reverse merger, a SPAC raises capital through the IPO and the PIPE (private investment), giving the company growth capital post-close.

Credibility. A SPAC has undergone an IPO process and SEC review, making it more credible than a reverse merger.

Sponsor reputation. Experienced SPAC sponsors (well-known entrepreneurs or investors) provide credibility and operational support to the acquired company.

Certainty. The deal structure provides certainty; capital is in trust, and the SPAC has a committed amount to pay for the acquisition.

Transparency. SPACs involve more disclosure and regulation than reverse mergers, protecting investors.

Disadvantages and criticisms

Excessive dilution. SPAC sponsors typically receive a 20% equity stake for forming the SPAC, even though they have not yet acquired a target. This represents significant dilution to public shareholders.

Overly optimistic projections. Private companies acquired by SPACs often make aggressive revenue and profitability projections to justify valuations. These projections frequently go unmet, disappointing public shareholders.

Conflicts of interest. SPAC sponsors have incentive to complete an acquisition quickly to earn their 20% stake, even if the target is not ideal. This can lead to value-destroying acquisitions.

Post-merger underperformance. Studies show that SPAC-merged companies often underperform comparable public companies and the broader market, suggesting that the valuations were excessive.

Regulatory gaps. SPACs face less regulatory scrutiny than traditional IPOs. Private companies going public via SPAC do not go through the same vetting process as traditional IPO companies.

Management churn. SPAC-acquired companies often see high executive turnover as the original SPAC team (sponsors and board) is replaced by the acquired company’s management.

The SPAC boom and bust

SPACs surged in popularity in 2020–2021, with hundreds of SPAC IPOs raising record amounts of capital. However, several high-profile SPAC failures and underperformance led to:

• Regulatory response. The SEC tightened rules governing SPAC disclosures and shareholder protections in 2021–2022.
• Market pullback. SPAC IPO activity collapsed in 2022–2023 as investors became wary.
• Redemption problem. Later SPACs saw widespread shareholder redemptions, leaving the SPAC with insufficient capital to close acquisitions.

By 2023–2024, SPAC activity had normalized to much lower levels.

Recent regulatory changes

The SEC has implemented stricter rules governing SPACs:

• Enhanced disclosure. SPACs must disclose financial projections and conflicts of interest more clearly.
• Sponsor compensation limits. Some rule proposals aim to reduce sponsor dilution.
• Redemption mechanics. Rules governing shareholder redemptions have been clarified.
• Warrant accounting. The accounting treatment of SPAC warrants has been tightened.

Comparison to other public entry mechanisms

vs. IPO. SPACs are faster and cheaper than IPOs, but IPOs involve more underwriter diligence and typically produce higher-quality public companies.

vs. Reverse Merger. SPACs are more credible and regulated than reverse mergers, but more expensive.

vs. Direct Listing. A direct listing allows a private company to go public by directly listing shares on an exchange, without raising new capital. This is simpler than a SPAC but does not raise capital for the company.
