Moscow, Russian Federation — Mobile TeleSystems PJSC (“MTS” – NYSE: MBT; MOEX: MTSS), the leading telecommunications provider in Russia and the CIS, announces that Sistema PJSFC (LSE: SSA, MOEX: AFKS), the parent company of MTS with effective ownership stake in MTS of 50.03 per cent, has declared that, as of 17 July 2017, a technical default has occurred on credit obligations amounting to approximately RUB 3.9 billion.

According to Sistema PJSFC, non-compliance with certain conditions of some of its credit facilities, which triggered the technical default, is driven exclusively by the arrest of the assets within the legal claim of Rosneft PJSC and Bashneft PJSOC with the Republic of Bashkortostan against Sistema PJSFC and its subsidiary Sistema-Invest JSC in May 2017. The technical default is purely formal in nature. Sistema PJSFC is servicing its credit and financial obligations in a timely manner and in full, and plans to continue doing so in the future.

Interested parties can learn more about the case from the disclosure of Sistema PJSFC - https://www.sistema.com/press/press-releases/detail/article/22785

The arrest of 31.76% of shares in the authorized capital of MTS held by Sistema PJSFC as well as the above-mentioned technical default of the corporation does not influence in any way the operational activities of MTS as well as does not impact the company's debt instruments.
