The Securities and Exchange Commission proposed sweeping amendments to IPO and periodic reporting rules on May 19, marking the biggest regulatory overhaul in over 20 years. The goal: reverse the nearly 40% drop in US publicly traded companies over the past three decades.

Under the proposal, the threshold for a "large accelerated filer" would nearly triple, from $700 million to $2 billion in public float, granting hundreds more companies reduced compliance costs.

The SEC also plans to extend shelf registration and communication safe harbors-currently reserved for the largest Well-Known Seasoned Issuers (WKSIs)-to a new category of issuers called "Eligible Listed Issuers" and "Seasoned Eligible Listed Issuers." This is a significant shift for mid-cap firms stuck between growth company exemptions and WKSI privileges.

Most notably, a proposed Form 10-S would allow reporting companies to file semiannual reports instead of quarterly Form 10-Q. The option is voluntary, not mandatory.

SEC Chairman Atkins framed the changes as a regulatory recalibration, not a rollback, emphasizing that investor protections remain intact.

Comments on the semiannual reporting proposal are due by July 6, 2026. Final implementation is months away, but the changes could reshape how companies approach going public and how investors assess risk.
