According to FINRA, Antoine Nabih Souma was barred from association with any FINRA member in all capacities after refusing to produce information and documents requested by FINRA.

FINRA's investigation concerned Souma's compliance with FINRA Rule 3280, which governs private securities transactions—also known as "selling away." Private securities transactions occur when registered persons sell securities outside their firm's regular business, without the firm's knowledge and approval. These transactions pose significant risks to investors because they occur without firm supervision, and customers may incorrectly believe the firm has vetted the investment and will provide regulatory protections.

FINRA also sent an additional request to Souma seeking information and documents related to an ongoing customer arbitration filed against him. Customer arbitrations often reveal important information about potential misconduct, and FINRA investigates to determine whether rule violations occurred and whether broader investor protection measures are needed.

When FINRA requested documents related to both the private securities transaction investigation and the customer arbitration, Souma refused to comply. This refusal violated FINRA Rule 8210, which requires members and associated persons to provide information and documents in connection with FINRA investigations, inquiries, complaints, and examinations.

The refusal to provide documents is treated as seriously as refusing to testify. Documents are often essential evidence in regulatory investigations, providing objective records of transactions, communications, and business arrangements. When registered persons refuse to produce documents, they prevent FINRA from conducting effective oversight and protecting investors.

The bar imposed on Souma is a permanent prohibition from associating with any FINRA member in any capacity. This severe sanction reflects the fundamental importance of regulatory cooperation to the self-regulatory system. Without the ability to compel document production and testimony, FINRA cannot effectively investigate potential misconduct.

For investors, this case illustrates the dangers of private securities transactions and the importance of regulatory cooperation. Souma's refusal to provide information about potential selling away and an ongoing customer dispute suggests he had something to hide. His bar from the industry protects investors from someone who demonstrated unwillingness to be transparent with regulators about matters directly affecting investor protection.
