Ad-Hoc Notice

November 03, 2015

Mobile TeleSystems PJSC (NYSE:MBT; MOEX: MTSS), the leading telecommunications provider in Russia, Central and Eastern Europe, announces that as the Company had previously disclosed, the US Department of Justice (DOJ) and the SEC are conducting an investigation into MTS’s business activities in Uzbekistan. In addition, MTS publicly confirmed that it had been referenced in a civil forfeiture complaint, filed by the DOJ, directed at certain assets of an unnamed Uzbek government official. The complaint alleges that MTS made corrupt payments to gain access to the Uzbek telecommunications market. The Complaint alleges among other things that MTS and certain other parties made corrupt payments to the unnamed Uzbek official to assist MTS entering and operating in the Uzbekistan telecommunications market. The Complaint is solely directed towards assets held by the unnamed Uzbek official, and none of MTS’s assets are affected by the Complaint.

Recent announcements with regard to Uzbekistan by MTS’s peers in the market have naturally raised questions among stakeholders and partners to MTS’s management. At this time, MTS can reiterate that it is cooperating with the investigation, and it is too early to draw any conclusions based on the experiences of others in the Uzbekistan market. As there have yet been no new developments, MTS can make no further comment or provide new information.
