What is a Form 8-A and when is a class of securities registered?

Information as of 15 October 2026. Everything below comes from the SEC's Form 8-A and Form 10, linked below. If anything here is wrong, tell us at contact@oqro.io and we will correct it.

What is a Form 8-A?

The SEC's Form 8-A is titled For Registration of Certain Classes of Securities Pursuant to Section 12(b) or (g) of the Securities Exchange Act of 1934. It is how a company puts a class of its securities on the register that the Exchange Act keeps. Section 12(b) covers securities listed on a national securities exchange, and the cover page asks for the title of each class and the name of the exchange. Section 12(g) covers classes that are registered without an exchange listing, and the cover page asks only for the title of the class.

It is a short form. It has two items: a description of the securities being registered, and a list of exhibits. The company can leave the long disclosures to other filings, which is why the form exists.

When can a company use it?

The form's general instructions say it may be used for any class of securities of an issuer that is required to file reports under Section 13 or 15(d) of the Act, that is concurrently qualifying a Tier 2 offering statement using the Form S-1 or S-11 disclosure models with audited financial statements, or whose exchange has been exempted from registration as a national securities exchange by order. Other companies register on the Form 10, which is titled General Form for Registration of Securities and covers the same two sections.

One more rule applies to a company that would owe an annual report for its last fiscal year, except that the registration will become effective before the report is due: the instructions say it must still file that annual report within the period the annual report form sets.

When does a registration take effect?

The instructions give different answers for the two sections. For a Section 12(b) registration, if the class is not being registered at the same time under the Securities Act, it takes effect on the later of two events: the SEC receives the exchange's certification, or the Form 8-A is filed. If the class is being registered under the Securities Act at the same time, as in an offering with its own registration statement, the form takes effect on the latest of three events: the filing of the Form 8-A, the SEC's receipt of the exchange's certification, and the effectiveness of the Securities Act registration statement.

For Section 12(g), registration takes effect on the filing, or, where the class is being registered under the Securities Act at the same time, on the later of the filing and the effectiveness of that statement. A class offered under Regulation A has its own rule, tied to the qualification of the offering statement, and the instructions add that it cannot be used if the Form 8-A is filed more than five calendar days after that qualification.

What does the form contain?

Item 1 asks for the description of the securities to be registered, with the information that Item 202 of Regulation S-K requires. The instruction lets the company incorporate by reference a comparable description already in an earlier filing, or in a prospectus that will be filed later. Item 2 is the list of exhibits. If the securities are registered on an exchange where other securities of the company are already registered, or under Section 12(g), the instructions say the documents that define the holders' rights have to be filed as exhibits, subject to the rule on incorporation of exhibits by reference.

The result is a form that is mostly cross-references. A reader who wants the terms of the securities follows them to the prospectus or to an earlier filing.

How does it relate to other filings?

A Form 8-A is the entry; the exits are covered in our articles on Form 25 and Form 15. Once a class is registered, the company's periodic reports follow the calendar described in our article on 10-K, 10-Q and 20-F deadlines.

What this does not tell you

A Form 8-A does not say when trading will start, what an offering price will be, or how many shares will be sold. It does not contain the company's financial statements; those are in the registration statement or the periodic reports the form points to. And it does not say that the company is a good or a bad one. It only records that a class of securities has been registered with the Commission.

OQRO describes the filing and its dates; it does not interpret the event or predict anything about a price. Nothing here is investment advice.
