On March 30, 2022, the US Securities and Exchange Commission ("Commission") proposed new rules and amendments to existing rules and forms (the "Proposed Rules," see summary) addressing the treatment of initial public offerings ("IPOs") by special purpose acquisition companies ("SPACs") and subsequent business combination transactions ("De-SPAC Transactions") between SPACs and operating companies ("Targets"). The Proposed Rules were published in the Federal Register on May 13, 2022 and the comment period has now closed.

The Securities Industry and Financial Markets Association, through its comment letter filed with the Commission, expressed support for increased disclosure related to SPAC IPOs and De-SPAC Transactions, but raised significant concerns about the newly proposed Rule 140a, which relates to gatekeepers in De-SPAC Transactions.
