Background & Discussion The FINRA/NYSE Trade Reporting Facility, the FINRA/Nasdaq Trade Reporting Facility Carteret and the FINRA/Nasdaq Trade Reporting Facility Chicago (the “Trade Reporting Facilities” or “TRFs”) provide FINRA members with a mechanism for reporting over-the-counter (OTC) trades in NMS stocks. Currently, the operating hours of the TRFs are 8:00 a.m. Eastern Time (ET) to 8:00 p.m. ET1 each business day.2 These operating hours are reflected in the transaction reporting rules for the FINRA/ Nasdaq TRFs (Rule 6380A (Transaction Reporting)) and the FINRA/ NYSE TRF (Rule 6380B (Transaction Reporting)). Generally, these rules require transactions executed between 8:00 a.m. and 8:00 p.m. on a business day to be reported as soon as practicable but no later than ten seconds after execution, while transactions executed at other times when the TRFs are closed must be reported by 8:15 a.m. after the TRF system opens. 1 Regulatory Notice 25-15 November 13, 2025

FINRA has amended its TRF reporting rules to provide that the TRF operating hours will now begin at 4:00 a.m. each business day.3 Under the amended TRF reporting rules, transactions executed between 4:00 a.m. and 8:00 p.m. on a business day must be reported as soon as practicable but no later than ten seconds after execution, while transactions executed at other times when the TRFs are closed must be reported by 4:15 a.m. after the TRF system opens. Specifically: X transactions executed between 9:30 a.m. and 4:00 p.m. on a business day must be reported as soon as practicable but no later than ten seconds after execution; X transactions executed between 4:00 a.m. and 9:30 a.m., or between 4:00 p.m. and 8:00 p.m., on a business day must be reported as soon as practicable but no later than ten seconds after execution with the unique trade report modifier to denote execution outside normal market hours; X transactions executed between midnight and 4:00 a.m. on a business day must be reported by 4:15 a.m. that business day with the unique trade report modifier to denote execution outside normal market hours; and X transactions executed between 8:00 p.m. and midnight, or on any non-business day, must be reported by 4:15 a.m. the next business day, designated “as/of” to denote execution on a prior day with the unique trade report modifier to denote execution outside normal market hours. The amendments will become effective on March 30, 2026.4 2 Regulatory Notice 25-15 November 13, 2025
