SPACs: An overview and assessment of returns

Abstract

AbstractSpecial purpose acquisition companies (SPACs) originated in the 1980s. A SPAC is a shell company formed by a sponsor to raise capital through a SPAC IPO to acquire or merge with an existing (target) private company. In a SPAC IPO, the units issued, consisting of (1) shares of common stock and (2) warrants, are typically priced at a nominal $10. Until 2022, SPAC IPOs were an increasingly popular alternative to traditional IPOs. We provide an overview of SPACs and an assessment of two measures of returns to SPACs, one is market‐adjusted buy and holds abnormal returns, and the other is risk‐adjusted abnormal returns by estimating a three‐factor regression model. The return calculations are based on 299 SPAC completed mergers between January 2013 and December 2021. Our results indicate that the main driver in a series of regressions, including various explanatory variables in explaining deSPAC returns, is the extent of warrants issued in a SPAC IPO, and robustness checks confirm these results.
