Manhattan, New York - Former Vice President of Alexion Pharmaceuticals, Joseph Dupont, 45, of Rehoboth, Massachusetts, and Slava Kaplan, aka "Stanley Kaplan," 45, a doctor residing in Hopewell Junction, New York, have been sentenced for their roles in an insider trading scheme related to the acquisition of Portola Pharmaceuticals by Alexion Pharmaceuticals, based in Boston, Massachusetts.

Key Points

• As the former vice president at Alexion, Dupont was privy to confidential information about the acquisition plans as of January 31, 2020.
• Before the public announcement of the acquisition in April 2020, Dupont misappropriated material, non-public information (MNPI) and shared it with a friend for trading purposes.
• The friend, in turn, passed this information to Kaplan, who used it for trading and shared it with a family member and a colleague.
• Following the public announcement on May 5, 2020, which led to a significant rise in Portola’s stock price, Kaplan and others sold their shares and options, earning millions in illegal profits.
• Both Dupont and Kaplan were arrested in June 2023 and pled guilty before their sentencing in 2023.
• Dupont was sentenced to three years' probation and was fined $75,000.
• Kaplan received a five-month prison sentence, three years of supervised release, and was ordered to forfeit $472,053.61.
