IPO Regulations

The Securities Act of 1933 governs the initial offering itself, requiring full and fair disclosure through the prospectus. The Securities Exchange Act of 1934 governs the company once public, requiring periodic financial reports (10-K, 10-Q) and prompt disclosure of material events (8-K) so that all market participants have access to the same information. IPO volume swings substantially with the macro cycle and the cost of capital — the 2021 boom saw over a thousand U.S. IPOs, and the count fell by more than 80% the following year as rates rose. That volatility is the norm; do not treat any single year’s IPO calendar as a signal.

Two other routes to a listing reached scale in that boom. A direct listing puts existing shares on the exchange with no underwriter and no new capital raised, which spares the company the underwriting spread and the first-day “pop” that hands value to the bank’s allocation clients — but also gives it no bookbuilding and no lockup. A SPAC (special-purpose acquisition company) is a listed shell that raises cash first and merges with a private company later, taking it public through the merger; roughly six hundred of the 2021 listings were SPACs. For the investor the SPAC is the one to be wary of: the sponsor’s “promote” hands it about 20% of the shell’s equity for a nominal price, the dilution lands on whoever holds the shares after the merger, and the 2021 vintage as a class trailed the market badly. Treat a SPAC target as a private-market deal that skipped the IPO diligence, not as an IPO.
