Alleged — pending

These are allegations. SEC has filed an action; nothing in it has been proven, and the respondents have not been found liable. Everything described on this page is what the regulator alleges, not what a court has found. See our editorial policy.

A dash means the release did not state a figure we could extract, not that the figure is zero. Penalty and disgorgement are stored separately so aggregates across the library do not double-count the same dollars.

What is alleged to have happened

the Securities and Exchange Commission announced this matter on April 19, 2022 as release LR-25372. The respondents named are Domenic Calabrigo, Curtis Lehner, Courtney Vasseur and Hasan Sario (4 individuals, 0 entities).

This library tags the matter as pump and dump and undisclosed control blocks, based on the conduct the regulator describes. Each tag links to a page explaining how that technique works, what statute it engages, and what penalties comparable actions have attracted. The tagging is ours, not the regulator's: agencies charge statutory provisions, not technique names.

The conduct is recorded against equities.

Non-monetary relief recorded: penny stock bar.

The release references a parallel criminal proceeding. Where a criminal case exists, the civil and criminal outcomes are recorded separately, because they resolve on different standards of proof.

This matter is at the allegation stage. Nothing in the regulator's filing has been proven, and the respondents are entitled to the presumption that it has not been. This page will be updated if the matter is resolved, dismissed or withdrawn.
