FINRA Sanctioned Steven Kosmaczewski For Failure To Testify

The regulatory action stemmed from FINRA's examination of Craft Capital Management, where Kosmaczewski worked at the time. FINRA initiated an investigation into the firm's securities transaction recommendations. As part of this investigation, FINRA requested Kosmaczewski’s testimony under FINRA Rule 8210. However, despite acknowledging receipt of the request, Kosmaczewski—through his lawyer—declined to appear for testimony. This refusal violated FINRA Rules 8210 and 2010, which require cooperation in regulatory investigations. The refusal ultimately resulted in a permanent bar.
