Form 10-K/A Filings

What Is SEC Form 10-K/A?

SEC Form 10-K/A is an amendment to a company’s annual report filed under the Securities Exchange Act of 1934. It is used to revise, correct, or add information to a previously filed annual report on Form 10-K.

This form is typically filed when a company identifies an error, omission, or required update in its original 10-K, such as correcting disclosures, updating exhibits, or adding previously unavailable information or information that was inadvertently omitted.

Form 10-K/A helps ensure the public record remains accurate by clearly identifying what is being changed from the original filing. Unless the amendment states otherwise, it generally does not update the entire 10-K for events that occurred after the original filing date, and it should be read together with the original annual report and related filings, including items discussed in 10-Q vs 10-K comparisons.

Key elements typically found in SEC Form 10-K/A include:

• Name of the registrant and Commission file number
• Fiscal year covered by the original Form 10-K
• Amendment number (for example, “Amendment No. 1”)
• Identification of the specific Items being amended
• Explanation of the changes and revised disclosures (if applicable)
• Updated exhibits, certifications, and signatures (as required)

SEC Form 10-K/A Filing Deadlines

SEC Form 10-K/A does not have a single fixed statutory deadline like the original Form 10-K. It is filed when a company needs to correct or update a previously filed annual report, including situations where Part III information is added later or when the company must refile amended disclosures. Users can learn more about these filings, including how to search for a specific Form 10‑K.

Key Things to Know About Form 10-K/A Filing Rules

• Amends a Previously Filed Annual Report: A company files Form 10-K/A to revise a prior 10-K filing and must clearly identify what sections or Items are being changed.
• Scope Is Limited to the Disclosed Changes: Form 10-K/A generally addresses only the specific corrections or additions described in the amendment and does not automatically refresh other parts of the original report.
• Exhibits and Certifications May Be Required: Depending on the nature of the amendment, updated exhibits, certifications, and signatures may be required under SEC rules and EDGAR filing requirements.
• Part III Updates Are a Common Use Case: Companies may use Form 10-K/A to add previously omitted Part III information when it is not incorporated by reference from a definitive proxy statement.
• Multiple Amendments May Occur: If additional corrections are needed later, registrants may file multiple amendments, typically labeled sequentially (for example, Amendment No. 1, Amendment No. 2).
