Discussion Background Rule 605 of SEC Regulation NMS (Rule 605) requires specified entities to publish monthly reports of statistical information concerning their order executions in NMS stocks. On March 6, 2024, the SEC adopted amendments to Rule 605 that broaden the scope of entities required to file Rule 605 reports beyond market centers to also include certain broker-dealers, as well as require broker-dealers operating alternative trading systems (ATSs) and single dealer platforms (SDPs) to prepare separate Rule 605 reports for such activity.1 The amendments also modify the scope and content of the required monthly detailed execution quality disclosures under Rule 605 and introduce a new monthly summary execution quality report. The amendments to Rule 605 will become effective on August 1, 2026, and the first set of monthly reports (for August 2026) under the amended rule must be published before the end of September 2026.2 Suggested Routing X Compliance X Legal X Operations X Systems X Technology X Trading X Training Key Topics X Disclosure of Order Execution Information X NMS Stocks Referenced Rules X Securities Exchange Act Rule 605 June 17, 2026

Rule 605 reports must be made available to the public in a uniform, readily accessible and usable electronic format in accordance with procedures established under the Rule 605 NMS Plan (605 Plan).3 Under the currently effective 605 Plan, each market center must arrange with a single 605 Plan Participant (i.e., FINRA or a national securities exchange) to act as the market center’s Designated Participant. The Designated Participant is responsible for assigning a unique market center identification code to each market center for which it acts as Designated Participant and must maintain a public website with hyperlinks to the Rule 605 reports for all market participants for which it acts as Designated Participant. Market centers selecting FINRA as their Designated Participant currently must mail or email a PDF Rule 605 Designated Participant Authorization Form to FINRA, and FINRA maintains a Market Centers website listing market center identification codes and hyperlinks for such market centers. In September 2025, the SEC approved amendments to the 605 Plan in light of the SEC amendments to Rule 605.4 The amended 605 Plan will become effective on August 1, 2026, to align with the effective date of the amendments to Rule 605.5 The amended 605 Plan will require each Designated Participant to assign a unique reporter identification code to each market center, broker, or dealer for which it acts as Designated Participant, and each market center, broker, or dealer is required to notify its Designated Participant of the hyperlink to the location where the entity’s Rule 605 reports are published. In connection with the upcoming amendments to Rule 605 and the 605 Plan, FINRA is modernizing its Rule 605 Designated Participant process by implementing a new electronic Rule 605 Designated Participant Authorization Form available through the FINRA Gateway.6 Requirement to Submit New Rule 605 Designated Participant Authorization Form All members required to publish Rule 605 reports under amended Rule 605 that select FINRA as their Designated Participant pursuant to the 605 Plan must submit the new electronic Rule 605 Designated Participant Authorization Form to FINRA in accordance with the process described below. This requirement applies to new entities becoming subject to Rule 605 for the first time as a result of the Rule 605 amendments (e.g., larger broker-dealers), as well as market centers already subject to Rule 605. All members must use the new electronic form to obtain a unique reporter identification code and provide a hyperlink to their Rule 605 reports, regardless of whether a member previously submitted the PDF form to FINRA. Members required to publish Rule 605 reports for multiple functions (e.g., larger broker-dealer, exchange specialist, OTC market maker, SDP, ATS) must submit a new, separate form and obtain a separate unique reporter identification code for each function.

X Reporter Identification Code (RIC): Market centers, brokers and dealers required to produce monthly Rule 605 reports must enter a Reporter Identification Code (RIC) in the form. The RIC serves as the unique tracking and identification mechanism for all reporters publishing Rule 605 reports and is required to be included in Field 2 (RprtEntityCd) of each reporter’s electronic Rule 605 data file as described in Exhibit A to the 605 Plan. A single entity performing multiple reporting functions must maintain separate RICs for each distinct function. Format Specifications:
y Exactly four (4) alphabetic characters only (e.g., ABCD). y No numerals or special characters permitted.7 Validation Step:
y Enter your proposed four-character alphabetic RIC in the designated field. y Select the “VALIDATE RIC” button. y The system will validate or reject your proposed RIC. y Validation Successful: The system confirms that your proposed RIC is acceptable and unique. y Validation Failed: The system rejects the proposed RIC (typically because it is already in use, contains invalid characters, or does not meet length requirements). You must select a different RIC and revalidate. Market centers that have previously produced Rule 605 reports under prior SEC requirements are permitted to continue using their historical Market Center ID as their RIC, provided the ID consists of four alphabetic characters. Market centers seeking to use their historical Market Center ID as their RIC should enter their four￾character alphabetic Market Center ID into the form as their RIC. X Reporter Type Selection: After your RIC has been validated, you must select the appropriate Reporter Type that best describes the function of the Rule 605 reporter associated with that specific RIC. Reporters must select from the following standardized Reporter Type categories:
y Exchange Market Maker y OTC Market Maker y Single Dealer Trading System (SDP) y Alternative Trading System (ATS) y National Securities Exchange y National Securities Association y Broker-Dealer

   Market Centers page on the FINRA website has been replaced with the new NMS Stock Order Execution Information (SEC Rule 605 Reports)
   page.
7. Firms may use the same MPID for some or all
   of their RICs and are not required to obtain new MPIDs as part of the Rule 605 Designated Participant Authorization process. The RIC used for Rule 605 publication purposes is independent from a firm’s MPID. Thus, RICs may be identical to, or different from, a firm’s MPID (e.g., a firm with MPID ABCD could obtain RIC ABCD or a different RIC such as WXYZ, depending on the firm’s preference).

8. This includes both the detailed monthly reports
   required under paragraph (a)(1) of Rule 605 and the new summary monthly reports required under paragraph (a)(2) of Rule 605.
9. The MPID and the RIC are separate and distinct
   identifiers. A single MPID may be used across multiple Rule 605 reportable functions requiring separate forms and RICs, while conversely, multiple MPIDs may support a single reportable function requiring only one form and associated RIC.
