The Securities and Exchange Commission charged Medallion Financial, a Delaware company headquartered in New York, and its president and chief operating officer, Andrew Murstein of New York, with illegally engaging in two schemes in an effort to reverse the company’s plummeting stock price.

According to the SEC’s complaint, Medallion’s core business was making loans backed by taxicab medallions to taxicab owners and operators. However, the popularity of ride-sharing companies like Uber and Lyft led to a decline in the value of taxicab medallions and of Medallion’s stock price. Murstein and Medallion allegedly directed two separate schemes to inflate the company’s stock price, in part with the help of California-based media strategy company Ichabod’s Cranium and its owner, Lawrence Meyers, both of whom were also charged by the SEC with fraud.

The complaint, filed in federal district court in Manhattan, alleges that Murstein and Medallion engaged in illegal touting by paying Ichabod’s Cranium and others to place positive stories about the company on various websites, including Huffington Post, Seeking Alpha and TheStreet.com. Meyers and others allegedly created fake identities with Murstein’s knowledge so their opinion pieces would appear credible to potential investors. The complaint further alleges that Medallion and Murstein fraudulently increased the carrying value of Medallion Bank, a wholly-owned subsidiary of Medallion, to offset losses relating to the taxicab medallion loans. The complaint alleges that when the existing valuation firm refused to cave to Murstein’s pressure to increase the bank’s valuation, Murstein fired the firm and hired a new firm to provide an inflated valuation of the bank.

“Murstein allegedly paid for more than 50 articles and hundreds of positive comments, which were really paid advertisements placed across the web in an effort to deceive investors about the value of Medallion’s stock,” Richard Best, director of the New York regional office of the SEC, said. “Companies also cannot shop for higher valuations when there is no evidence to support them.”

The SEC’s complaint charges Murstein and Medallion with violating the antifraud, books and records, internal controls and anti-touting provisions of federal securities laws. Murstein is also charged with making false statements to Medallion’s auditor. The complaint also charges Ichabod’s Cranium and Meyers with touting and fraud. The SEC is seeking permanent injunctions, disgorgement plus prejudgment interest and civil penalties. In addition, the SEC is seeking an officer-and-director bar against Murstein.

The SEC’s investigation was conducted by Olivia Zach, Kenneth Gottlieb and David Stoelting, and supervised by Celeste Chase and Best of the New York regional office. The litigation will be handled by Stoelting.
