What Is SEC Form SC 13E1/A?

SEC Form SC 13E1/A is an important filing required under Rule 13e-1 of the Securities Exchange Act of 1934. It is used by an issuer to amend a previously filed Schedule 13E-1 when there is a material change in the facts or disclosures relating to the issuer’s proposed purchases of its own equity securities while it is the subject of a third-party tender offer.

This form is typically filed when the issuer has already submitted Schedule 13E-1 and later needs to update the filing because the terms, timing, purpose, source of funds, or other material information have changed. Because it is event-driven, the filing is made as needed.

Form SC 13E1/A ensures transparency by updating investors and regulators when material changes occur in a previously reported Rule 13e-1 transaction. It does not create a new filing regime, but rather amends the existing disclosure so that the SEC record remains current during the tender offer process. Related disclosure may also appear in filings such as SEC Form 8-K.

Key elements typically found in SEC Form SC 13E1/A include:

  • Name of the issuer and class of securities involved
  • Reference to the previously filed Schedule 13E-1
  • Description of the material changes being reported
  • Updated purpose of the proposed purchases, if applicable
  • Updated source and amount of funds or other consideration
  • Any revised exhibits or supporting disclosures

SEC Form SC 13E1/A Filing Deadlines

SEC Form SC 13E1/A does not have a fixed periodic deadline. It is filed when a material change occurs in the information previously reported in a Schedule 13E-1, so timing depends on the underlying transaction and the need to keep the disclosure current.

Key Things to Know About Form SC 13E1/A Filing Rules

  • Material Change Standard Applies: SC 13E1/A is used only to amend a previously filed Schedule 13E-1 when the issuer needs to report a material change in the information already disclosed.
  • Not a Standalone Initial Filing: This form does not replace the original Schedule 13E-1. It functions as an amendment and must be read together with the initial filing.
  • Event-Driven Rather Than Periodic: There is no annual, quarterly, or fixed calendar deadline. The form is filed only when circumstances change, and an updated disclosure is required.
  • Electronic Filing Still Required: SC 13E1/A is a recognized EDGAR submission type and is filed electronically with the SEC as an amendment to Schedule 13E-1.
  • Used During an Active Third-Party Tender Offer: The amendment remains tied to Rule 13e-1, which governs issuer purchases of equity securities while the issuer is the subject of a third-party tender offer.
