The U.S. Justice Department and Securities and Exchange Commission have subpoenaed Snap for information about its March 2017 initial public offering, the social media app maker told Reuters on Tuesday.
Snap said in a statement it has responded to the government subpoenas and other requests for information.
The previously unreported federal inquiries follow an ongoing shareholder lawsuit in which investors allege that Snap misled the public about how competition from Facebook's Instagram service had affected the company's growth.
Snap said it believes that the federal regulators "are investigating issues related to the previously disclosed allegations asserted in the class action about our IPO disclosures."
"While we do not have complete visibility into these investigations, our understanding is that the DOJ is likely focused on IPO disclosures relating to competition from Instagram," the company said.
