FINRA Rule 5190

SEC Regulation M and the Anti-Manipulation Framework

FINRA Rule 5190 is procedural — it does not itself prohibit conduct but rather requires notifications that enable FINRA's Market Regulation Department to monitor compliance with the substantive trading restrictions of SEC Regulation M. Understanding FINRA Rule 5190 therefore requires understanding what SEC Regulation M does and why the monitoring function FINRA Rule 5190 enables is essential.

SEC Regulation M — codified at 17 CFR Part 242, Rules 100 through 105 — was adopted by the SEC in 1997, replacing the prior Regulation U and Rules 10b-6, 10b-6A, 10b-7, and 10b-8 under the Exchange Act. SEC Regulation M is designed to prevent manipulation of the market price of a security by persons with an interest in the outcome of its offering — primarily underwriters, broker-dealers, issuers, selling security holders, and their affiliated purchasers. The core concern is that an underwriter who needs to sell a block of securities at a particular price has an incentive to support that price artificially through purchases in the secondary market during the distribution period, creating a false impression of demand that facilitates the offering at the expense of investors who buy on the basis of that manufactured market activity.

SEC Regulation M Rule 101 prohibits distribution participants — underwriters, prospective underwriters, and their affiliated purchasers — from bidding for, purchasing, or inducing any person to bid for or purchase any covered security during the applicable restricted period. SEC Regulation M Rule 102 imposes corresponding restrictions on issuers and selling security holders. SEC Regulation M Rule 103 governs NASDAQ passive market making — a limited exception that allows market makers who are also distribution participants to continue some market-making activity during a distribution under specified conditions. SEC Regulation M Rule 104 governs stabilization, syndicate covering transactions, and penalty bids — the specific post-offering trading activities that the rule permits under defined conditions. SEC Regulation M Rule 105 prohibits the purchase of securities in certain offerings after short sales in the same security.

The restricted period — the window during which SEC Regulation M Rule 101's trading restrictions apply — is either one business day or five business days before pricing, depending on the trading volume and public float characteristics of the covered security. Securities meeting SEC Regulation M's definition of actively traded — those of issuers with at least a $150 million public float and average daily trading volume of at least $1 million — are exempt from the restricted period and may be traded by distribution participants without restriction during the distribution. FINRA Rule 5190's notification obligations apply differently depending on whether the offering is subject to a restricted period or qualifies as actively traded, with separate notification tracks for each.

Rule 5190(b): Definitional Framework

FINRA Rule 5190(b) provides that for purposes of the rule, the following terms carry the meanings set forth in SEC Regulation M Rules 100 and 101: actively traded, affiliated purchaser, covered security, distribution, distribution participant, offering price, penalty bid, restricted period, selling security holder, and syndicate covering transaction. This definitional cross-reference to SEC Regulation M rather than to independently defined FINRA terms is deliberate — it ensures that FINRA Rule 5190's notification obligations are precisely calibrated to the scope of SEC Regulation M's substantive restrictions, preventing definitional gaps or inconsistencies between the notification trigger and the underlying conduct rule.

The definition of distribution participant is particularly significant because it determines which entities are subject to FINRA Rule 5190's notification requirements. Under SEC Regulation M Rule 100, a distribution participant is an underwriter, prospective underwriter, broker, dealer, or other person who has agreed to participate or is participating in a distribution — a broad definition that captures not only the lead manager and co-managers but all selling group members, all broker-dealers who have agreed to participate in the selling effort, and their affiliated purchasers. FINRA Rule 5190's notifications must identify all distribution participants, including those that join the syndicate or selling group after the initial notification has been filed — a requirement that has been a recurring source of FINRA Rule 5190 violations when firms update their participant lists incompletely or untimely.

Rule 5190(c): Notifications for Restricted Period Distributions

FINRA Rule 5190(c) establishes the primary notification framework for distributions subject to a restricted period under SEC Regulation M Rule 101. Three separate notifications are required.

The first notification — FINRA Rule 5190(c)(1)(A) — must be filed no later than the business day prior to the first complete trading session of the applicable restricted period. This pre-commencement notification must include the managing member's determination of whether a one-day or five-day restricted period applies and the basis for that determination, the contemplated date and time of commencement of the restricted period, the security name and symbol, and identification of all distribution participants and affiliated purchasers. The business-day-prior deadline reflects the operational reality that FINRA's Market Regulation Department must have advance notice to monitor compliance with the restricted period from its very first trading session — a restricted period that FINRA does not know about until after it has begun cannot be effectively monitored from the start.

The phrase unless later notification is necessary under specific circumstances accommodates the genuine operational reality that some offerings move on a compressed timeline that does not allow full business-day advance notice. An offering that is priced on an accelerated basis — as is common for investment-grade corporate bond offerings and secondary equity offerings by well-known seasoned issuers that can be executed overnight — may not allow the full business-day advance notice that the standard timeline contemplates. In these cases, firms must still provide the required notification as promptly as circumstances allow, and the fact that circumstances required a shorter notice period should be documented.

The second notification — FINRA Rule 5190(c)(1)(B) — must be filed no later than the close of business the next business day following the pricing of the distribution. This post-pricing notification must include the security name and symbol, the type of security, the number of shares offered, the offering price, the last sale before the distribution, the pricing basis, the SEC effective date and time, the trade date, the restricted period, and identification of all distribution participants and affiliated purchasers. The post-pricing notification gives FINRA's Market Regulation Department the definitive offering terms after they are set, enabling verification that the restricted period ran from the correct date and time and that all relevant participants were identified. The requirement to identify distribution participants in both the pre-commencement and post-pricing notifications — and to ensure those identifications are complete and accurate — is the element that has generated the most enforcement findings under FINRA Rule 5190.

The third notification — FINRA Rule 5190(c)(1)(C) — must be filed immediately upon any cancellation or postponement of a distribution for which a pre-commencement restricted period notification has already been submitted. When an offering is pulled — whether because of adverse market conditions, issuer issues, or any other reason — FINRA needs to know immediately so that the restricted period restrictions on distribution participants can be lifted. A distribution participant that is unnecessarily constrained from trading by a restricted period that applies to an offering that no longer exists has suffered a competitive disadvantage that the cancellation notification is designed to eliminate promptly.

FINRA Rule 5190(c)(2) addresses the scenario where a FINRA member is acting as issuer or selling security holder — rather than as underwriter — in a distribution subject to a restricted period. Such member-issuers and member-selling security holders are subject to SEC Regulation M Rule 102's parallel trading restrictions and must comply with the same FINRA Rule 5190(c)(1) notification requirements, unless another member has assumed responsibility in writing for that compliance.

The written assumption of responsibility provision — appearing in FINRA Rule 5190(c), (d), and (e) — reflects the organizational reality of large syndicated distributions. The managing underwriter, as the central coordinator of the offering, typically assumes responsibility for filing the required notifications on behalf of all distribution participants. When such an assumption of responsibility has been documented in writing, individual distribution participants who are not the manager are relieved of their independent notification obligation. The written assumption must be affirmative and specific — a general understanding or verbal arrangement does not qualify. In the absence of a written assumption, each distribution participant and affiliated purchaser that is a FINRA member bears independent notification responsibility.

Rule 5190(d): Notifications for Actively Traded Securities

FINRA Rule 5190(d) establishes a separate, simpler notification track for distributions of securities that qualify as actively traded under SEC Regulation M Rule 101 — and therefore are not subject to a restricted period. For actively traded distributions, the managing member must file a single post-pricing notification no later than the close of business the next business day following pricing. That notification must include the manager's determination that no restricted period applies under SEC Regulation M Rule 101 and the basis for that determination, together with the same pricing information required for restricted period distributions under FINRA Rule 5190(c)(1)(B) — security name and symbol, type of security, number of shares, offering price, last sale, pricing basis, SEC effective date and time, trade date, and identification of distribution participants and affiliated purchasers.

The distinction between restricted period and actively traded notifications is significant from a compliance management perspective. For actively traded offerings, there is no pre-commencement notification to file — only the single post-pricing report. The managing underwriter must nevertheless make and document the determination that the actively traded exception applies before relying on it, because a firm that proceeds without a restricted period when one is required has violated SEC Regulation M Rule 101 regardless of whether it ultimately files any notification at all.

Rule 5190(e): Penalty Bids and Syndicate Covering Transactions

FINRA Rule 5190(e) addresses two specific post-pricing distribution-related trading activities in OTC equity securities — penalty bids and syndicate covering transactions — that are permitted under SEC Regulation M Rule 104 subject to specified conditions. Both are mechanisms used by underwriting syndicates to manage the aftermarket for an offering.

A syndicate covering transaction is an open market purchase of the offered security by the managing underwriter in the aftermarket to cover an oversold position — the short position created when the underwriter sells more shares than it has actually purchased from the issuer, using the overallotment or greenshoe option to create a price-stabilization mechanism. When the security's aftermarket price declines below the offering price, the managing underwriter can purchase shares in the open market and use those purchases to cover the short, which simultaneously supports the price and closes the overallotment position.

A penalty bid is a provision in the syndicate agreement allowing the managing underwriter to reclaim the selling concession paid to a selling group member whose customers have sold — flipped — the shares allocated to them in the offering within a short period after pricing. The penalty bid creates a financial disincentive to short-term flipping by selling group members, supporting aftermarket price stability.

Both activities must be disclosed to FINRA under FINRA Rule 5190(e). Before imposing a penalty bid or engaging in the first syndicate covering transaction, the managing member must file a pre-activity notification identifying the security and its symbol and the date such activity will occur. Within one business day of completing such activity, a post-activity confirmation must be filed identifying the security and its symbol, the total number of shares, and the dates of the activity. The FINRA Rule 5190(e) notification requirement applies only to OTC equity securities — defined in FINRA Rule 6420 — reflecting the greater price sensitivity and manipulation risk in the OTC market compared to exchange-listed securities where exchange surveillance systems provide additional oversight.

The Electronic Submission Process and FINRA Gateway

Regulatory Notice 12-19, effective in 2012, established the current electronic process for submitting all FINRA Rule 5190 notifications. All required notifications — the Regulation M Restricted Period Notification, the Regulation M Trading Notification, and the Regulation M Notice of Intent to Impose a Penalty Bid and/or Effect a Syndicate Covering Transaction — must be submitted electronically through FINRA Gateway to FINRA's Market Regulation Department. Paper submissions by fax, email, or third-party vendor that were previously acceptable were replaced by this centralized electronic process, which enables FINRA's Market Regulation surveillance systems to ingest and process offering participant data more efficiently and to cross-reference it with trade surveillance data.

FINRA publishes comprehensive guidance on the electronic submission process on its Regulation M filings page, including the specific forms, required fields, and step-by-step instructions for each notification type. Firms that have questions about specific offerings or submission requirements are directed to FINRA's Market Regulation Department at (240) 386-5560 or by email.

Enforcement Context and the 2024 AWC

FINRA Rule 5190 compliance failures have generated a consistent pattern of enforcement findings, typically appearing in AWCs that also cite FINRA Rule 3110 supervisory deficiencies. In the first half of 2024, FINRA and several national securities exchanges resolved an AWC with a broker-dealer for untimely or inaccurate restricted period notifications filed in connection with security distributions. The AWC found that certain FINRA Rule 5190 notifications filed by the firm did not identify all participants in the distributions — including participants who joined the syndicate after the initial restricted period notification was submitted — and did not identify the participants correctly as FINRA members. In other instances, the firm did not timely file required trading notifications or submitted notifications with incomplete participant identification. FINRA found that the firm's supervisory system was deficient with respect to verifying the timeliness and accuracy of required notifications, constituting a violation of FINRA Rule 3110 alongside the FINRA Rule 5190 violations.

The enforcement pattern reveals the two most common failure modes for FINRA Rule 5190 compliance: timing failures — notifications submitted after the required deadlines — and completeness failures — notifications that omit distribution participants, particularly those who join after the initial filing, or that fail to correctly identify participants as FINRA members. Both failure modes share a common root cause: supervisory procedures under FINRA Rule 3110 that do not include systematic verification that notifications are complete, accurate, and timely. Firms whose compliance programs do not include a specific checklist or workflow for FINRA Rule 5190 notification preparation, review, and filing — with clear ownership and a defined timeline for each notification type — are structurally at risk of these failures.

Supervisory Obligations and Written Supervisory Procedures

FINRA Rule 5190 compliance requires specifically tailored written supervisory procedures under FINRA Rule 3110. Those WSPs must address the process for determining whether any securities offering the firm participates in as a distribution participant triggers FINRA Rule 5190 notification obligations, who within the firm is responsible for preparing and reviewing each type of required notification, the timelines applicable to each notification type — pre-commencement restricted period notifications due by the business day prior to commencement, post-pricing notifications due by the next business day following pricing, cancellation notices required immediately — and the review process for verifying that all distribution participants are completely and accurately identified in each notification.

WSPs should also address the process for updating notifications when new distribution participants join the syndicate after an initial notification has been filed, the procedures for obtaining and documenting written assumptions of responsibility when the firm is relying on a managing underwriter to file notifications on its behalf, and the process for identifying when the firm is acting as issuer or selling security holder subject to FINRA Rule 5190(c)(2). The supervisory control testing required by FINRA Rule 3120 should include periodic review of FINRA Rule 5190 notification compliance, including timeliness verification against offering calendars and completeness verification against syndicate participant lists.

Examination Relevance and Key Takeaways

FINRA Rule 5190 is tested on the Series 7 General Securities Representative examination in the context of underwriting, new issues, and the regulatory framework governing securities offerings. The Series 24 General Securities Principal examination tests the rule in greater depth covering the specific notification requirements, their deadlines, the participant identification obligations, and the supervisory framework for ensuring compliance. The rule's connection to SEC Regulation M — and specifically the restricted period and actively traded concepts — makes it essential knowledge for any examination candidate covering the regulatory environment for securities distributions.

The key points to retain are these: FINRA Rule 5190 sets forth notification requirements for all FINRA members participating in securities offerings for purposes of monitoring compliance with SEC Regulation M, which prohibits distribution participants from bidding for or purchasing covered securities during the applicable restricted period to prevent manipulation of the offering market; terms used in FINRA Rule 5190 carry the definitions from SEC Regulation M Rules 100 and 101 — including distribution participant, covered security, restricted period, actively traded, affiliated purchaser, penalty bid, and syndicate covering transaction; for distributions subject to a restricted period under SEC Regulation M Rule 101, the managing member must file a pre-commencement notification no later than the business day prior to the first complete trading session of the restricted period identifying the restricted period length determination and all distribution participants, a post-pricing notification by the next business day following pricing, and an immediate cancellation or postponement notice if the offering is pulled; for actively traded distributions exempt from a restricted period, a single post-pricing notification is required by the next business day following pricing including the basis for the actively traded determination and full participant identification; FINRA Rule 5190(e) requires pre-activity notice before imposing a penalty bid or first syndicate covering transaction in OTC equity securities defined in FINRA Rule 6420, and post-activity confirmation within one business day of completion; all notifications must be submitted electronically through FINRA Gateway to Market Regulation following the process established in Regulatory Notice 12-19; one member may assume written responsibility for filing notifications on behalf of all distribution participants — absent such written assumption each FINRA member distribution participant bears independent notification responsibility; a 2024 AWC confirmed that failure to identify all distribution participants — particularly those joining after initial notification — and failure to identify them correctly as FINRA members constitutes a FINRA Rule 5190 violation accompanied by a FINRA Rule 3110 supervisory deficiency; and written supervisory procedures under FINRA Rule 3110 must specifically address the offering review process for determining whether FINRA Rule 5190 obligations apply, the notification preparation and verification workflow, participant identification completeness requirements, the update process when new participants join, and the timelines applicable to each notification type.
