Withum and Marcum audited over 78% of all SPACs since 2020

Special purpose acquisition companies, otherwise known as SPACs, have flooded the equity markets over the last couple of years. According to, SPAC IPOs in the United States more than quadrupled in 2020 compared to 2019. The acceleration of SPACs continued in 2021. US SPAC IPOs in 2021 more than doubled compared to 2020.

The rush of SPACs certainly came with financial reporting issues and regulatory scrutiny. According to Nicola White’s Bloomberg article, approximately 70% of companies that had reported accounting restatements in February and March 2022 were either SPACs or companies that became publicly traded via SPAC merger (also known as de-SPACs).

With all these accounting and financial reporting issues, it begs the question: who is auditing the SPACs? We dug through the data and arrived at some very interesting findings.

Only 5 audit engagement partners audited over 23% of the 789 SPACs since 2020

We reviewed the SEC filings (10-K, 20-F, etc.) for SPACs starting from 2020-01-01 through the present. During this time frame, there were 789 SPACs with audited SEC filings. A total of 193 audit engagement partners audited these SPACs.

Below were the top 5 audit partners by number of SPACs audited since 2020. These 5 audit engagement partners audited over 23% of all SPACs in the last year and a half!
