Executive Summary

Interest in special purpose acquisition companies (SPACs) has skyrocketed in recent years. As of May 7, 315 SPACs have been launched so far this year, surpassing the 248 in 2020. Although SPACs have become a larger portion of private-to-public corporate transitions, a majority continue to go the route of traditional initial public offerings (IPOs).

The Securities and Exchange Commission (SEC) defines a SPAC as “a company with no operations that offers securities for cash and places substantially all the offering proceeds into a trust or escrow account for future use in the acquisition of one or more private operating companies.”1 SPACs raise capital to take companies public, similar to an IPO.

SPACs initially serve no commercial purposes; in fact, the only asset on their balance sheet is the cash they raise at launch. With that capital in tow, managers of the SPAC search for a private company that desires to go public. If all parties manage to come to an agreement, the two companies merge and the funds held in the SPAC are exchanged for equity in the post-merger company. As a result, the private company now trades on a public exchange.

SPAC traits

Following are a few pros and cons of SPACs and how they compare to traditional IPOs.


  • Both SPACs and IPOs require extensive SEC review processes, but SPACs are not subject to some of the more rigorous IPO disclosures; consequently, the review process may take less time.
  • Investors can approve or reject a deal through a proxy vote, and investors have redemption rights to back out of a deal.
  • Investors can trade shares before an acquisition.
  • There may be more certainty as to pricing and control over deal terms. Market value of IPO shares can fluctuate considerably due to the absence of a prior public market, unseasoned trading, the small number of shares available for trading and limited information about the issuer, among other factors.
  • SPAC investors can get in before the IPO run-up, which has become commonplace, especially among tech IPOs.


  • Often referred to as “blank check companies,” a SPAC is like a mystery box — investors won’t know what it eventually holds until it finds a suitable target company.
  • Public shares have historically faced large dilution costs, as founders carve out a share for themselves and investors opting out of deals leave remaining shareholders holding the bag on underwriting fees.
  • Although SPACs issue shares for roughly $10 and value their shares at $10 when they merge, by the time of the merger the median SPAC holds cash of just $6.67 per share.2
  • Some companies that go public via IPOs may have clear growth prospects, solid management teams and other factors that may make them less risky than companies targeted through SPACs, which may not always be obvious candidates to go public.

PACs and sustainability 

More recently, sustainability-oriented companies have chosen to go public by being acquired by a SPAC to bypass the traditional IPO process and take advantage of increasing investor enthusiasm to harness their ability to combat climate change.

Buyer beware

A recent study3 found that shareholder dilution, as measured by the amount of pre-acquisition cash remaining in the SPAC per share, has often been a key determinant to realized returns for shareholders in the six months following the acquisition. Results varied widely, from -85% to +163%, a track record of mixed and widely disparate results. As a result, the longer-term performance of SPACs appears highly speculative, and their surge in popularity may be another sign of recent market ebullience. Investors should tread carefully in this space, as a consummated merger is not guaranteed and dilution costs to SPAC shareholders can be significant.
