FINRA Charged Lowry With Engaging In Scheme Relating To IPOs

Specifically, on March 17, 2026, FINRA’s Department of Enforcement initiated Case No. 2021071714201 against John Lowry.

Consequently, FINRA seeks sanctions against Lowry.

Allegations Regarding Restricted Share Sales

According to FINRA, Spartan Capital and certain employees allegedly sold restricted pre-IPO shares through a short-selling process known as “deemed owned,” which allegedly allowed insiders to sell shares more quickly than clients who held the same securities. FINRA alleged that clients were directed through a slower process for removing share restrictions while the firm and select employees sold shares earlier at higher prices. The regulator further alleged that clients were not informed about the quicker process allegedly used by Spartan and some employees. FINRA stated that Spartan employees and the firm allegedly generated more than $50 million in profits before clients were able to complete the process needed to sell their shares.

The regulator also alleged violations involving Section 17(a)(2) and Section 17(a)(3) of the Securities Act of 1933. In addition, FINRA claimed Spartan failed to disclose certain compensation associated with the underwriting of the pharmaceutical company’s IPO, including cash and shares allegedly connected to preparation for the uplisting process.
