A special purpose acquisition company (SPAC) is a company formed to raise money through an initial public offering (IPO). It uses those funds to merge with or acquire an operating business. The operating business is commonly referred to as the target and is typically a private company trying to access public markets.
SPACs are often described as blank check companies. This is because, at the time of their IPO, they do not have an active business or identified acquisition target. Instead, investors commit funds based on the strategy of the SPAC and the reputation of its sponsors. In practice, this means investors are placing trust in the management team to identify and complete a suitable deal.
The core objective of a special purpose acquisition company SPAC is to provide an alternative route for a private company to become a public company. Rather than going through a traditional IPO, the private company merges with the already listed special purpose acquisition company. This process allows the target company to access liquidity and public market capital without completing its own IPO process.
A special purpose acquisition company (SPAC) follows a structured process from formation to merger. The execution involves several stages that financial professionals and advisors should understand in detail.
It starts with a management team or sponsor with experience in a specific industry or sector. These sponsors organize the entity, establish its strategy, and lead the search for a suitable acquisition target. In most cases, the sponsor contributes only nominal capital but receives a significant ownership stake through founder shares.
Founder shares usually account for about 20% of the SPAC's equity while the remaining 80% is held by public shareholders. At the time of the IPO, investors typically purchase "units." These IPO units often consist of shares of common stock combined with warrants or rights to acquire additional shares later.
In terms of governance, founder shares and public shares generally carry similar voting rights, but sponsors often retain control over key decisions.
Once formed, the SPAC proceeds with its initial public offering (IPO). Unlike a traditional operating company, the SPAC does not offer products or services. Its only purpose at this stage is to raise capital. The IPO proceeds are placed in a trust account invested in low-risk instruments and are reserved for completing a future acquisition or returning capital to investors if no deal is completed.
Most SPACs are marketed based on an investment thesis. This may focus on a particular industry, sector, or geographic region. Importantly, the special purpose acquisition company does not disclose a specific target at the time of the IPO, meaning investors commit capital without knowing the eventual acquisition.
After the IPO, the SPAC enters its operational phase. It typically has 18 to 24 months to identify and complete a merger with a target private company. If the SPAC fails to complete a transaction within this timeframe, two things may happen:
In case of liquidation, the funds held in the trust account are returned to public shareholders, generally close to the original IPO price. This limited timeframe creates pressure on sponsors to complete a deal, which can influence negotiation dynamics and transaction quality.
Once a target is identified, the SPAC announces the proposed merger or the business combination. At this stage, more detailed information about the target company becomes available to investors. Generally, the SPAC then seeks a shareholder vote to approve the transaction. Public shareholders are given the opportunity to evaluate the deal and decide whether to support it.
A key feature of this process is the redemption right. Investors who do not wish to participate in the merger may choose to redeem their shares and receive a return of their invested capital from the trust account. This option is available regardless of how they vote on the transaction.
In many cases, the funds raised during the IPO are not sufficient to complete the acquisition. To address this, SPACs often raise additional capital through private investment in public equity (PIPE) transactions.
PIPE financing involves institutional investors committing funds alongside the merger.
This additional funding helps maintain a minimum cash balance required to complete the transaction and support the combined company's operations after the blank check merger.
Once the merger receives shareholder approval and all regulatory requirements are satisfied, the transaction is completed. The SPAC and the target company combine in what is often referred to as a de-SPAC transaction.
At this stage, the company must meet disclosure and reporting requirements including filings with the Securities and Exchange Commission. These filings provide detailed financial and operational information about the newly combined entity.
Following completion, the target company effectively becomes a public company. It begins trading on a public exchange and is subject to the same regulatory obligations as other listed entities.
In a traditional IPO, a private company offers its shares to the public for the first time. This process typically involves investment banks acting as underwriters who help prepare regulatory filings, market the offering, and determine pricing. The company itself goes through the listing process and becomes a public company directly.
By contrast, a special purpose acquisition company SPAC is already a publicly listed shell entity. Instead of issuing shares directly to the public, the private company merges with the SPAC. Through this merger, the private company effectively becomes publicly traded without undergoing the conventional IPO process.
Here's more on the two:
Tax considerations in special purpose acquisition company (SPAC) investments can be complex and depend on transaction structure, investor profile, and jurisdiction. Redemption rights may trigger capital gains or losses while different instruments can carry separate tax treatments. As a result, tax outcomes may change throughout the lifecycle of a SPAC investment.
The structure of a de-SPAC transaction can affect tax outcomes for investors and target company shareholders. Many SPAC mergers aim to qualify as tax-deferred reorganizations, but cash consideration, reverse mergers, cross-border transactions, or other structural variations can trigger taxable gains.
Evaluating a special purpose acquisition company (SPAC) transaction today requires a far more disciplined and structured approach than during the 2020–2021 boom. With tighter regulation, more sophisticated investors, and a clear track record of what has failed, advisors must focus on fundamentals, alignment, and execution readiness before recommending participation in any deal.
Assess sponsor track record
The starting point for any SPAC evaluation is the sponsor. Advisors should examine:
Unlike earlier cycles dominated by pre-revenue or projection-heavy businesses, today's viable targets are expected to demonstrate:
Dilution remains one of the most critical risks in SPAC transactions. Multiple layers contribute to this, including sponsor promotes, warrants, PIPE financing, and high redemption levels among existing shareholders. Advisors should:
The structure of the transaction provides key insight into both risk and investor confidence. In particular, PIPE (private investment in public equity) participation has become a critical signal of deal quality. Key considerations include:
One of the most important lessons from the previous SPAC cycle is that failure often occurs after the merger. Advisors should evaluate operational readiness with these markers:
Companies that lack this infrastructure at the time of the transaction are likely to face significant execution risk once operating as a public entity.
Why are SPACs no longer popular? Here's an explainer about why interest fizzled:
Special purpose acquisition companies (SPACs) remain a viable alternative route for private companies seeking to enter the public markets. Their appeal lies in speed, negotiated valuation, and access to experienced sponsors who can provide both capital and strategic guidance.
However, the lessons of the past cycle made one reality clear: the benefits of SPACs are inseparable from their risks. As a result, due diligence and regulatory awareness are essential. Investors and advisors must fully understand the evolving regulatory environment, particularly in the United States.
