Item 4.

Purpose of Transaction

The description contained herein supplements Item 4 in the Schedule 13D and should be read in connection therewith:

On September 6, 2017, the Issuer announced the repurchase of its shares of common stock (“Shares”) and ADSs by means of a share repurchase plan under Rule 10b5-1 under the Securities Exchange Act of 1934 in the total aggregate amount of up to RUB 20,000,000,000 (the “Repurchase Plan”), which amount includes funds used for purchasing the Issuer’s shares from Sistema Finance as described below, until April 2019. The Repurchase Plan is carried out by the Issuer’s wholly-owned subsidiary Stream Digital, LLC (the “Purchaser”).

Sistema Finance also entered into a sale and purchase agreement (the “Sale and Purchase Agreement”) (Exhibit C hereto) with the Purchaser, whereby Sistema Finance agreed to sell to the Purchaser a number of the Issuer’s Shares proportionate to the number of 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 Issuer 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. Sistema Finance may refuse to sell the Issuer’s Shares to the Purchaser by giving the Purchaser notice before the beginning of a reporting period/month in which the Purchaser contemplates acquiring the Issuer’s Shares and ADSs under the Repurchase Plan, and may in this notice set a minimum price at which Sistema Finance agrees to transfer the Shares to the Purchaser.

On October 6, 2017, the Issuer announced that the Purchaser purchased 8,456,757 Shares from Sistema Finance, which is equivalent to 0.42% of the issued share capital of the Issuer. The amount of the transaction totaled RUB 2,388 mln.

On November 10, 2017, the Issuer announced that the Purchaser purchased 8,138,237 Shares from Sistema Finance, which is equivalent to 0.41% of the issued share capital of the Issuer. The amount of the transaction totaled RUB 2,298 mln.

Subject to the conditions mentioned herein and in the Schedule 13D, the Reporting Persons may acquire additional Shares or ADSs and/or sell or hold Shares or ADSs currently held.
