Update—legal proceedings

After the annual report was finalized on March 3, 2022, Ericsson learned that Telefonaktiebolaget LM Ericsson and certain officers of Ericsson were named as defendants in a putative class action filed in the United States District Court for the Eastern District of New York. The complaint alleges violations of United States securities laws, in connection with allegedly false and misleading statements principally concerning the Company’s adherence with its compliance and disclosure policies and obligations and the conduct of its business in Iraq.
