Engineer charged with insider trading related to Three Mile Island nuclear plans, allegedly profiting .5 million.
A federal indictment has been issued against Casey Muggleston, an engineering manager at Constellation Energy, on charges of insider trading related to the planned reopening of the uranium-powered electric plant at Three Mile Island. The indictment was announced following an extensive investigation conducted by the FBI in both Maryland and Delaware.
Muggleston is accused of profiting approximately .48 million through illicit stock option trades, utilizing material nonpublic information acquired in his capacity as part of the team tasked with securing licensing approvals from the Nuclear Regulatory Commission (NRC) for the reactor’s restart. The indictment underscores the serious nature of the charges, with allegations centering on Muggleston’s use of confidential company insights to benefit financially in the stock market before the official public announcement concerning the plant’s reopening.
According to the indictment, Muggleston began purchasing call options on Constellation’s stocks, thereby positioning himself for substantial financial gains tied to the anticipated rise in stock value following the company’s public confirmation of its intentions regarding the plant. This strategic move was timed closely ahead of the announcement, indicating his prior knowledge of the company’s decision-making process, which he allegedly referred to internally as “Project Tetris.”
The federal charges against Muggleston include securities fraud and four counts of insider trading, each carrying the potential for significant prison time. If convicted, he faces a maximum of 105 years in prison, although sentencing for white-collar crimes is often significantly reduced from maximum guidelines. The government is also pursuing the forfeiture of the illicit profits gained through these transactions.
In addition, the Securities and Exchange Commission (SEC) has filed a civil complaint outlining Muggleston’s activities, which allegedly extend to discussions involving confidential company matters well into 2025. While three of his relatives are said to have engaged in similar option purchases, they have not been charged.
Constellation has publicly acknowledged the indictment but has refrained from commenting further due to Muggleston being no longer employed by the company. The company plans to proceed with the reactor’s reopening, a move backed by various government officials, including President Donald Trump and Governor Josh Shapiro, despite concerns raised by environmental advocates about the safety and speed of the reactor’s restart. Constellation aims to commence loading uranium into the Three Mile Island reactor in the spring and anticipates supplying power as early as late 2027. The facility, known for its history following the partial meltdown in 1979, has remained a point of contention regarding safety and environmental impacts.
The actions of Muggleston, as outlined in the indictment, reflect a significant breach of ethical and legal standards expected from employees in sensitive positions within the energy sector, particularly in contexts involving regulatory compliance and market integrity.
