Form 10-12B/A Filings

What Is SEC Form 10-12B/A?

SEC Form 10-12B/A is an amendment to a Form 10-12B registration statement filed under Section 12(b) of the Securities Exchange Act of 1934. It is used by registrants to revise, supplement, or correct disclosure previously submitted when registering a class of securities for exchange listing, often in connection with transactions such as a spin-off or other corporate reorganization.

This form is typically filed in response to SEC staff comments, to provide updated financial statements or exhibits, or to reflect material changes that occur after the initial Form 10-12B submission. Each amendment becomes part of the public EDGAR record for the registration statement.

Form 10-12B/A helps ensure the registration statement remains accurate and complete before it becomes effective, supporting investor transparency while the registrant finalizes its Exchange Act registration disclosures. The underlying Form 10-12B establishes the original registration statement, while Form 10-12B/A is used to revise or supplement information in that filing.
