The TransMedics Group (TDMX) Class Action
The complaint alleges that TransMedics made false and misleading statements, while failing to disclose crucial information. Specifically, the suit contends that TransMedics used kickbacks, fraudulent overbilling, and coercive tactics to boost business and revenue. Furthermore, it alleges that the company engaged in unsafe practices, concealed safety problems, and generally lacked adequate safety oversight, exposing TransMedics to heightened regulatory risk.
The lawsuit details two events that allegedly disclosed defendants’ misconduct to the market that adversely impacted the company’s stock price. On February 21, 2024, Representative Paul Gosar issued a letter accusing TransMedics of misappropriating corporate resources. The allegations were subsequently reported by The Daily Caller on February 22, 2024, causing a drop in TransMedics' stock price, according to the complaint.
More recently, on January 10, 2025, activist short seller Scorpion Capital released a report leveling accusations against TransMedics, including overbilling hospitals, coercing customers into using specific services, and providing patients with organs rejected by reputable physicians via doctors allegedly paid by TransMedics.
This report further depressed the company’s stock price, the lawsuit claims.
Prominent investor rights firm Hagens Berman Sobol Shapiro LLP is probing whether TransMedics misled investors regarding its sales practices.
“We are looking into claims that TransMedics engaged in improper billing practices and concealed safety issues. These allegations, if true, could have significant implications for both patients and investors,” said Reed Kathrein, the Hagens Berman partner leading the investigation.
