Ad-Hoc Notice

September 6, 2017

Mobile TeleSystems Public Joint Stock Company (the “Company”)

ANNOUNCEMENT OF ADOPTION OF RULE 10B5-1 PLAN

On September 6, 2017, the Company announced that its Board of Directors has approved the repurchase of its shares of common stock and ADSs by means of a share repurchase plan in the total aggregate amount of up to RUB 20,000,000,000 (the “Repurchase Plan”), which amount includes funds used for purchasing the Company’s shares from Sistema Finance as described below, until April 2019. The Company will execute the Repurchase Plan under Rule 10b5-1 of the Securities Exchange Act of 1934, as amended, and Rule 10b-18 of the Exchange Act.

The Repurchase Plan will be carried out by the Company’s wholly-owned subsidiary Stream Digital, LLC (the “Purchaser”). RUB 20,000,000,000 is equal to approximately US$345,721,694 translated at the CBR’s exchange rate of RUB 57.85 to US$1.00 as of September 6, 2017.

A plan under Rule 10b5-1 allows the Company to repurchase its shares and ADSs at times when it otherwise might be prevented from doing so under insider trading laws or because of self-imposed trading blackout periods. A broker selected by the Company will have the authority under the terms and limitations specified in the plan to repurchase the Company’s shares and ADSs on the open market in accordance with the terms of the plan. Repurchases are subject to the regulations of the United States Securities and Exchange Commission as well as certain price, market volume and timing constraints specified in the plan. The Company may terminate the plan at any time.

The Repurchase Plan comes into effect on September 6, 2017 and is effective until April 2019. Any actual repurchases under the Repurchase Plan will be disclosed in the Company’s annual reports on Form 20-F and Form 6-K filed with the Securities and Exchange Commission and as required under legislation of the Russian Federation.

Purchases from Sistema Finance

Sistema Finance S.A. (“Sistema Finance”), a Luxembourg subsidiary of the Company’s majority shareholder Sistema Public Joint Stock Financial Corporation (“Sistema”) has also entered into a sale and purchase agreement (the “Sale and Purchase Agreement”) with the Purchaser, whereby Sistema Finance agreed to sell to the Purchaser a number of the Company’s shares of common stock proportionate to the number of the Company’s shares and ADSs to be purchased by the Purchaser under the Repurchase Plan in each reporting month at the average price per share calculated for a relevant month such that Sistema’s (together with its affiliated entities’) aggregate percentage ownership and voting power in the Company after the Repurchase Plan will be substantially equal to Sistema’s and such affiliates’ ownership as at the date of the commencement of the Repurchase Plan. Moreover, Sistema Finance is entitled to refuse to sell the Company’s shares to the Purchaser by giving the Purchaser a respective notice before the beginning of a reporting period/month, in which the Purchaser contemplates to acquire the Company’s shares and ADSs under the Repurchase Plan, as well as to set in this notice a minimal price at which Sistema Finance agrees to transfer the shares to the Purchaser.
