What is a Form 15 filing? SEC deregistration guide (2026)

By Flock Research · Filings research desk

A Form 15 filing is the certification a company files with the Securities and Exchange Commission (SEC) to deregister a class of securities and suspend its duty to file periodic reports. It is the filing behind what the market calls "going dark": a company that files a Form 15 stops publishing 10-Ks, 10-Qs, and 8-Ks. This guide explains what a Form 15 filing is, the thresholds that allow it, and when it takes effect. It is not investment advice.

A Form 15 filing

is a certification filed with the SEC to deregister a class of securities and suspend a company's Exchange Act reporting duties. It is used when record holders fall below set thresholds, and it stops the flow of periodic reports such as the 10-K and 10-Q. Source: SEC.

What are the thresholds for filing a Form 15?

A company cannot simply choose to stop reporting; it must fall under record-holder limits first. In broad terms, a class of securities qualifies when it is held of record by:

  • Fewer than 300 persons, or
  • Fewer than 500 persons if the company's total assets have not exceeded $10 million on the last three fiscal year-ends, or
  • Fewer than 1,200 persons for a bank or bank holding company.

"Held of record" counts registered holders, so shares held in street name through a broker can sit behind a single record holder. That is why a company with many beneficial owners can still fall under the threshold.

When does a Form 15 take effect?

The timing has two parts. Filing the Form 15 immediately suspends the company's periodic reporting duties, so the next 10-Q or 10-K need not be filed. Deregistration under Section 12(g) then becomes effective 90 days after the filing. If the company later crosses back over the record-holder limit on the first day of a fiscal year, its reporting duty can be reinstated.

Why does a Form 15 matter to someone reading filings?

A Form 15 is the point where a company's public disclosure trail can go quiet. Once it is effective, the audited annual report and quarterly updates stop, so anyone tracking that company loses the regular filing stream. Spotting the Form 15 on EDGAR is how you know the reporting has ended rather than assuming a late filing.

Going dark versus going private

A Form 15 is a quiet deregistration. It is different from a full going-private transaction, where an affiliate buys out public holders and files a Schedule 13E-3 with a fairness statement. For the difference between the two exits, see Schedule 13E-3 vs Form 15. To find either on the regulator's own system, see how to search SEC EDGAR.
