How do special-purpose acquisition companies (SPACs) work?

A special-purpose acquisition company (SPAC) is a shell corporation that is involved in the process of taking a company public on the stock market. Also referred to as a ‘blank check company’, it's formed and listed on a local stock exchange with the purpose of acquiring a private company and raising capital. It can then take the company public without going through the traditional initial public offering​ (IPO) process.

What is a SPAC?

SPAC stands for a special-purpose acquisition company, which is also known as a 'blank check company'. This type of company is created without any commercial operations in mind. It aims to raise capital through an IPO that can then be used to acquire an existing company, in what is called a reverse-merger.

This method of taking a company public has been used for a number of decades, but SPACs saw a dramatic rise in 2020 as companies hit by the Covid-19 crisis looked for alternative ways to raise capital. In 2020, 248 SPACs were listed, in comparison with only 209 traditional IPOs.

What is the structure of a SPAC?

Pre-merger phase

  1. Target companies: usually, the founders of a SPAC will have one or more companies they are planning to target. During the process of raising capital however, these targets are not revealed. This means that investors in the IPO don't know which company their investment might be used towards.
  2. Funding: the founders of the SPAC usually provide the starting capital, and then institutional investors and underwriters are the main targets for raising capital before the public can trade SPAC shares​. The capital raised during a SPAC IPO will be secured in a trust account. It can only be used to conduct an acquisition, or return the funds back to the investors if the SPAC is liquidated.
  3. SPAC IPO: the shares are then made public on the stock market through a SPAC IPO, which usually cost around $10 per share plus interest. Traders can speculate on these shares through derivatives, such as spread bets and CFDs.
  4. Marketing: the SPAC usually issues a press release to announce the upcoming acquisition of the target company, which is a crucial part of the process. Third-party trader speculation around the potential target of a SPAC and its potential for future growth and success can help to promote the SPAC. In turn, this bumps up the demand and subsequently, its share price, upon flotation on a stock exchange.

Post-merger phase

  1. Voting: after the deal is announced, a redemption and vote phase takes place where shareholders can exchange their shares for net asset value, if they are not happy with the deal or shares are trading below that level.
  2. Lock-up period: this refers to the period after a SPAC IPO in which shareholders are restricted from selling shares. This can be up to 180 days from closing. Some investors may prefer shorter lock-up periods so they can trade on any volatile price action that results from the process, and cash out their positions earlier.
  3. Completion: there is usually a defined period (between 18-24 months) for a SPAC to complete an acquisition, or it may be liquidated. Any interest earned can be used as working capital.

SPAC examples

Some recent examples of major companies taken public on the stock market through a special-purpose acquisition company include Virgin Galactic and DraftKings.

Space stock​ Virgin Galactic completed its reverse-merger in October 2019 with the SPAC named Social Capital Hedosophia. The company, founded by Richard Branson, received approximately $800m in funding from the original SPAC, and then earned $460m more through a secondary offering in August 2020.

SPAC stock

SPACs are a great way to raise capital for innovative companies at a time when markets are under pressure. For example, large companies including Virgin Galactic have listed with a SPAC, which shows that SPACs are not just used for smaller or startup businesses. It's possible to trade SPAC stocks, as well as their target companies that were merged. Below are some popular SPACs you can trade on our Next Generation platform via spread betting and CFD trading:

  • Social Capital Hedosphia Holdings: this is a partnership between the investment firms of Social Capital and Hedosophia. The SPAC aims to unite technology-oriented entrepreneurs and investors around a shared vision of identifying and investing in innovative and agile technology companies.

As SPACS become more popular in the world of investing, exchange-traded funds​​ (ETFs) have been created to give investors more exposure to these types of companies. The aim of this type of fund is to invest in SPACs and SPAC-merged companies, and these can be either passive or actively managed.

Special-purpose acquisition companies often publicise innovative and tech-savvy companies in particular, as these pose long-term potential for growth. However, the risks of SPAC ETFs remain the same as SPAC shares; these companies are not guaranteed success for the future and could fall upon entering the stock market. Given that SPAC ETFs have not had as much time to develop, there are only a few floating across the market right now, although this may change in the months and years to come.

Special-purpose acquisition company: pros and cons

Benefits of a SPAC

  • SPACS often invest in highly innovative companies that its founders expect to grow and develop within their respective industry, which is appealing for investors. This presents opportunities for speculative trading once the company’s shares are issued to the public.
  • SPAC stocks can be highly volatile at times. Share prices may trade for a lower price than their IPO, so traders may be able to use short-selling strategies to profit from price falls.
  • As the raised funds are kept in a trusted account, there is less downside risk for investors. If the SPAC is liquidated, their funds will be returned, provided they are not used within the defined time period.
  • Investors have a say in which acquisition target is being pursued. The voting process means that they can opt out of an opportunity and have their funds returned, or they can vote in favour of a target acquisition. This contrasts with a traditional venture capital process where you cannot influence how your funds are used.
  • A reverse-merger is often quicker and cheaper than a traditional IPO, as explained above. There is also less timing risk or an IPO window that must be met, which can sometimes have an adverse effect on an IPO’s success.

Drawbacks of a SPAC

  • Although volatility may be preferred by some investors, highly speculative shares can also put off a trader. For example, a startup company that showed promising potential can end up falling in the stock market and you could get caught up on the wrong side of the trade. This is why risk-management controls and tools are important for traders.
  • With both SPACs and IPOs, investing in startups and pre-revenue companies can come with risks. Once a vote to merge has happened, investors are no longer able to redeem shares at net asset value. If the share is unsuccessful, this could make their profits drop.
  • Valuation of SPAC stocks often overtake the underlying fundamentals of the company. Some investors worry that the SPAC market will be short-lived and then drop.
  • If there are too many new SPAC listings, the market may not be able to handle the overflow. The process is becoming increasingly popular and may even overtake the IPO market at some point.

What’s a SPAC stock?

Special-purpose acquisition companies are listed on a national stock exchange, which means that their shares can be traded like any other company. Find out how to trade stocks through spread betting and CFD trading.

Can you lose money in a SPAC?

It's possible to lose money in a SPAC investment if the target company does not perform well after going public on the stock market. Not all IPOs are successful. By analysing company fundamentals, you can gain insights into the possible direction of a share price, based on available earnings reports and cash flow for example.

Are SPACS good investments?

SPACs can be seen as a good investment as they have lower costs and a narrower timeline than a traditional IPO. However, SPAC shares can end up trading below their IPO prices on the opening day. Therefore, you should consider all associated risks before investing in a SPAC.

What happens if a SPAC fails?

If a SPAC fails to complete a merger within the given time period, it's then liquidated and the IPO earnings are returned to its shareholders. This means that you don't lose any capital that you funded into the SPAC, minimising your capital risk.

Who are SPAC sponsors?

SPAC sponsors can fall into a number of groups, including private investors, equity funds and experienced business executives. SPAC sponsors typically receive around 20% of common equity in the SPAC for an investment of 3-4% of the IPO funding.

What does SPAC mean?

SPAC stands for special-purpose acquisition company, which is an alternative method to taking a company public on the stock market. A SPAC is often referred to as a 'blank check company' that raises capital for its own version of an initial public offering (IPO), acquiring their target company in the process.
