Leidos Holdings, a Virginia-based information technology, engineering, aerospace, and defense firm, disclosed it is under investigation by federal law enforcement for alleged violations of the Foreign Corrupt Practices Act (FCPA).

In a quarterly filing issued Tuesday, Leidos said its internal processes discovered possible violations of the FCPA in late 2021 by its “employees, third-party representatives, and subcontractors” who work for the company’s international business.

The company launched an internal investigation into the alleged violations of the FCPA and voluntarily reported the existence of the probe to both the Department of Justice (DOJ) and Securities and Exchange Commission. The company’s internal investigation is ongoing, Leidos said in its disclosure.

In September, the company said it received a federal grand jury subpoena related to a criminal investigation by the U.S. attorney for the Southern District of California, “in conjunction with the U.S. Department of Justice’s Fraud Division.” That subpoena requested information about the violations of the FCPA that are the focus of the company’s internal investigation, the company said.

In addition, the company also received a separate subpoena in August for a criminal investigation of alleged violations of U.S. antitrust law being conduct by the DOJ’s Antitrust Division. That investigation is related “to three U.S. government procurements associated with the company’s intelligence group in 2021 and 2022.”

The company said it is in the process of responding to both subpoenas and that it intends to fully cooperate with the investigations.
