Legal Status This site displays a prototype of a “Web 2.0” version of the daily
Federal Register. It is not an official legal edition of the Federal
Register, and does not replace the official print version or the official
electronic version on GPO’s govinfo.gov.

The documents posted on this site are XML renditions of published Federal
Register documents. Each document posted on the site includes a link to the
corresponding official PDF file on govinfo.gov. This prototype edition of the
daily Federal Register on FederalRegister.gov will remain an unofficial
informational resource until the Administrative Committee of the Federal
Register (ACFR) issues a regulation granting it official legal status.
For complete information about, and access to, our official publications
and services, go to About the Federal Register on NARA's archives.gov.

The OFR/GPO partnership is committed to presenting accurate and reliable
regulatory information on FederalRegister.gov with the objective of
establishing the XML-based Federal Register as an ACFR-sanctioned
publication in the future. While every effort has been made to ensure that
the material on FederalRegister.gov is accurately displayed, consistent with
the official SGML-based PDF version on govinfo.gov, those relying on it for
legal research should verify their results against an official edition of
the Federal Register. Until the ACFR grants it official status, the XML
rendition of the daily Federal Register on FederalRegister.gov does not
provide legal notice to the public or judicial notice to the courts.

Securities and Exchange Commission

1. [Release No. 34-104975; File No. SR-CboeBZX-2026-004] March 11, 2026. On January 8, 2026, Cboe BZX Exchange, Inc. filed with the Securities and Exchange Commission (“Commission”), pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) [1 ] and Rule 19b-4 thereunder, [2 ] a proposed rule change to amend the Opening Auction Process provided under Rule 11.23(b)(2)(B) to delay the Opening Auction under certain market conditions in order to improve price discovery and allow executions to occur at prices that better reflect current market conditions. The proposed rule change was published for comment in the Federal Register on January 27, 2026. [3 ]

Section 19(b)(2) of the Act [4 ] provides that within 45 days of the publication of notice of the filing of a proposed rule change, or within such longer period up to 90 days as the Commission may designate if it finds such longer period to be appropriate and publishes its reasons for so finding or as to which the self-regulatory organization consents, the Commission shall either approve the proposed rule change, disapprove the proposed rule change, or institute proceedings to determine whether the proposed rule change should be disapproved. The 45th day after publication of the notice for this proposed rule change is March 13, 2026. The Commission is extending this 45-day time period.

The Commission finds it appropriate to designate a longer period within which to take action on the proposed rule change so that it has sufficient time to consider the proposed rule change and the issues raised therein. Accordingly, the Commission, pursuant to Section 19(b)(2) of the Act, [5 ] designates April 27, 2026, as the date by which the Commission shall either approve or disapprove, or institute proceedings to determine whether to disapprove, the proposed rule change (File No. SR-CboeBZX-2026-004).

For the Commission, by the Division of Trading and Markets, pursuant to delegated authority. [6 ]

Vanessa A. Countryman,

Secretary.
