UnitedHealthcare CEO Brian Thompson was one of several executives at the company under investigation by the Justice Department when he was shot outside a Manhattan hotel on Wednesday.

Thompson – who was killed in what police called a targeted shooting outside the Hilton hotel in Midtown – exercised stock options on Feb. 16, selling $15.1 million worth of shares, less than two weeks before the news of the federal antitrust investigation became public, according to an April report by Crain’s New York Annual Report.

The stock price fell sharply after news that the Justice Department was investigating whether the company had made acquisitions that consolidated its market position in violation of antitrust laws, a source familiar with the investigation told the outlet.

Thompson’s stock options reportedly had several years to expire, and the sale of the shares was his first since taking over as head of parent company UnitedHealth’s insurance division in 2021.

According to the report, Thompson, 50, along with UnitedHealth Group Chairman Stephen Helmsley, Chief People Officer Erin McSweeney and Chief Accounting Officer Tom Roos, sold a total of $101.5 million in shares, with Helmsley personally took in almost $85 million.

Charles Elson, founding director of the Weinberg Center for Corporate Governance at the University of Delaware, told Crain’s that stock sales by company executives are typically reviewed by a company’s general counsel, who can determine whether additional disclosures to the market may be necessary before closing are transactions are being carried out.

Earlier this year, UnitedHealth was hit by one of the largest healthcare data breaches in U.S. history. The company estimated that up to a third of Americans’ private data – possibly including Social Security numbers – was compromised in the ransomware attack.
