MTS Successfully Passes Compliance Management Surveillance Audit Under ISO

June 29, 2022

MOSCOW, Russia – Mobile TeleSystems Public Joint Stock Company (“MTS” or “the Company”) (NYSE: MBT; MOEX: MTSS), Russia’s largest mobile operator and a leading provider of media and digital services, announces that it has reached a major compliance milestone by successfully passing a surveillance audit as International Compliance Association Risk Management (ICA Risk Management) verified the effectiveness of MTS compliance management system.

The auditors recognized that MTS operates in line with international standards on compliance management. As a result of this recognition, MTS has successfully transferred to a standard “Compliance Management Systems” (ISO 37301:2021, formerly ISO 19600:2014) and has confirmed its compliance with international standards concerning anti-bribery management systems (ISO 37001:2016).

In January 2021, MTS started a new three-year recertification audit cycle after receiving its first ICA Risk Management compliance certification in 2018. The January 2022 Surveillance Audit confirmed that MTS implemented all the recommendations given by the auditors in 2021. This further reconfirms MTS’s aspiration and long-term commitment to following international expertise and best practice to reinforce transparency and integrity across the full spectrum of the Company’s activities.

Looking ahead, the Company remains committed to developing and improving its Unified Compliance System as a part of its compliance strategy, and to enhancing its sustainability and efficiency in a changing environment.
