According to FINRA, Michael Robert Greenfield was permanently barred from association with any FINRA member firm in January 2026 pursuant to FINRA Rule 9552(h), for failure to provide information or keep information current as required by FINRA rules. The bar became effective January 26, 2026.FINRA Rule 9552(h) authorizes the permanent bar of individuals who fail to comply with their obligation to provide information or maintain current registration disclosures, and who do not cure the deficiency within the specified timeframe. All registered persons in the securities industry are required to maintain current and accurate information with FINRA, including through timely updates to their registration filings and by responding to FINRA's regulatory requests. This ongoing transparency requirement allows FINRA to monitor the fitness of industry participants and enables investors to access accurate background information through tools like BrokerCheck.The specific circumstances underlying the information failure are not detailed in the public disciplinary report for this matter. However, the permanent bar means Greenfield may no longer associate with any FINRA member firm in any capacity. Investors who worked with Greenfield should review their account history for any concerns and may consult FINRA BrokerCheck for his complete regulatory record. A permanent bar is FINRA's most severe sanction against an individual and signals that the regulator determined Greenfield's failure to maintain required transparency warranted his permanent exclusion from the securities industry.
