Special-Purpose Acquisition Company
A special-purpose acquisition company (SPAC) is a publicly traded shell corporation created by experienced investors or operators (sponsors) to raise capital specifically to acquire a private company. The SPAC conducts an initial public offering, and the raised capital is held in a trust account pending identification of a target company. Once a target is identified, the SPAC merges with the operating company in a de-SPAC transaction, effectively taking the private company public. SPACs are an alternative to traditional initial public offerings for private companies seeking to access public markets.
How a SPAC is structured
SPAC sponsors (typically seasoned executives, investment professionals, or industry experts) form a shell company and conduct an IPO. The IPO prospectus discloses that the SPAC has no operating business and will use the raised capital (held in a trust) to identify and acquire a private operating company within a specified timeframe (usually 24 months).
Public investors in the SPAC IPO pay $10 per share (or a different price set by the sponsors). The sponsors contribute their own capital (typically $20–30 million or more) and receive founder shares at nominal cost. The trust holds the IPO proceeds until a merger target is identified.
SPAC sponsors and promote structure
SPAC sponsors earn a return through a “promote”: they receive founder shares equal to a percentage of the public shareholders’ stake (typically 20 percent of the IPO shares). If the SPAC IPO raises $500 million in 50 million shares, sponsors receive 12.5 million founder shares for a nominal investment. These founder shares are in-the-money if the SPAC successfully merges and the resulting company trades above $10 per share.
This structure aligns sponsor incentives to execute a merger but also creates incentives for sponsors to overpay for mediocre targets or accept overly optimistic financial projections.
The merger and redemption process
Once the SPAC identifies a target, it negotiates a merger agreement. The merger is then submitted to shareholders (both SPAC and often the target company) for a vote. SPAC shareholders can vote to approve the merger or redeem their shares at the trust account value plus accrued interest (typically the IPO price plus interest, roughly $10.50 per share).
If shareholders redeem in large numbers, the amount of capital available to the merged company shrinks. A $500 million SPAC that sees 60 percent redemptions has only $200 million left for the operating company post-merger. This redemption risk is a key feature of SPACs: public shareholders have a straightforward exit if they don’t like the target.
PIPE and institutional support
To address redemption risk and signal confidence in the target, SPACs often secure PIPE (Private Investment in Public Equity) commitments. Institutional investors commit to buying shares in the merged company at a fixed price (typically close to the $10 SPAC IPO price) after the merger closes. A $500 million SPAC with 60 percent redemptions but a $300 million PIPE commitment ends up with $500 million in capital: $200 million from non-redeeming public shareholders plus $300 million from PIPE investors.
Advantages of SPACs for private companies
A SPAC allows a private company to go public without the cost and timeline of a traditional IPO. An IPO requires extensive SEC registration, audits, investor roadshows, and underwriter negotiations, typically taking 6–12 months. A SPAC merger can close in 3–6 months, faster and often cheaper (though SPAC sponsors’ promotes, PIPE discounts, and transaction fees can offset the underwriter savings).
A SPAC also provides price certainty. The private company can lock in a valuation upfront (through the merger agreement) rather than risk market conditions that affect IPO pricing. This is valuable when equity markets are volatile or when the company wants to avoid the uncertainty of price discovery during an IPO roadshow.
Additionally, a SPAC allows the private company’s founders and management to negotiate favorable terms. In a traditional IPO, the company must accept institutional investor preferences regarding board structure and governance. A SPAC merger lets founders retain more control and potentially more board seats.
Disadvantages and risks
SPAC shareholders have expressed growing skepticism about SPAC deals. The SPAC market exploded in 2020–2021, with hundreds of SPACs raising capital, but many SPAC mergers have underperformed. Studies show the median SPAC company underperforms the market significantly in the three years post-closing.
The SEC has noted concerns about SPAC financial projections, which are often overly optimistic. Projections are subject to legal liability (under federal securities laws), but enforcement has been limited, leading to a credibility problem.
Additionally, SPAC structures involve substantial sponsor promote economics. The founders’ 20 percent stake in a $500 million SPAC is worth $100 million if the stock is at $10 per share, all for minimal capital contribution. This creates a strong incentive for sponsors to execute a deal, even if the target is mediocre.
Regulatory changes
The SEC has introduced rules to tighten SPAC disclosures and protect shareholders. Recent rules limit sponsor promotes, require more detailed financial projections, and require sponsors to have “skin in the game” by not allowing early liquidation of founder shares.
As of 2024–2025, the SPAC market has cooled significantly due to investor skepticism and regulatory tightening. Fewer SPACs are being formed, and SPAC mergers trade at steep discounts (often below the $10 IPO price).
Post-merger operations
After a SPAC merger closes, the combined company is a fully reporting public company subject to all SEC and Sarbanes-Oxley obligations. Investors often become acquainted with the business through the proxy statement released before the shareholder vote, but many SPAC investors do not deeply research the target before voting.
Warrants and SPAC complexity
Most SPACs issue warrants (call options to buy SPAC shares at a fixed price, typically $11.50) alongside IPO shares. Warrants trade separately and have their own dynamics. The warrant value depends on the probability that the SPAC merger succeeds and the merged company’s stock trades above the warrant’s strike price. Warrant valuations can be complex and are subject to substantial volatility.
