SCHEDULE TO

This Amendment No. 1 (the “Amendment No. 1”) to Tender Offer Statement on Schedule TO amends and supplements the Tender Offer Statement on Schedule TO initially filed by Stream Digital, LLC (the “Offeror”), a wholly-owned subsidiary of Mobile TeleSystems Public Joint Stock Company (the “Company”), with the Securities and Exchange Commission on January 17, 2017 (together with any amendments and supplements thereto, the “Schedule TO”) , pursuant to Rule 13e-4 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Schedule TO relates to the return of cash to holders of shares of common stock, par value RUB 0.10 per share (the “Common Stock”) and American Depositary Shares (“ADSs”) of the Company, by way of a cash tender offer by the Offeror for shares of the Company’s Common Stock (including shares of Common Stock represented by ADSs) up to a maximum aggregate purchase amount of RUB 4,647,186,170, on the terms and subject to the conditions set forth in the Offer to Purchase, dated January 17, 2017 (the “Offer to Purchase”), the related Common Stock Letter of Transmittal with respect to the shares of Common Stock and the related ADS Letter of Transmittal with respect to the ADSs (which collectively, as they may be amended and supplemented from time to time, constitute the “Tender Offer”), copies of which were filed with the initial Schedule TO as Exhibits (a)(1)(i), (a)(1)(ii) and (a)(1)(iv), respectively, as supplemented by the Supplement to Offer to Purchase dated February 1, 2017 (the “Supplement”).

This Amendment No. 1 to the Schedule TO, as it amends and supplements the Schedule TO, is intended to satisfy the reporting requirements of Rule 13e-4(c)(2) under the Exchange Act. Only those items reported in this Amendment No. 1 are amended or supplemented. Except as specifically provided herein, the information contained in the Schedule TO, the Offer to Purchase and the related Common Stock Letter of Transmittal with respect to the shares of Common Stock and the related ADS Letter of Transmittal with respect to the ADSs remains unchanged.

All information in the Supplement is hereby expressly incorporated by reference in response to all of the items in this Schedule TO, and as more particularly set forth below. Such information amends and supplements the information previously incorporated by reference in this Schedule TO. This Amendment No. 1 should be read in conjunction with the Schedule TO, the Offer to Purchase, the related Common Stock Letter of Transmittal with respect to the shares of Common Stock, the related ADS Letter of Transmittal with respect to the ADSs and the Supplement, as the same may be further amended or supplemented hereafter and filed with the SEC.

As of January 31, 2017 zero shares of Common Stock (including shares of Common Stock represented by ADSs) have been tendered and not withdrawn.

Capitalized terms used and not defined herein have the meanings assigned to such terms in the Offer to Purchase.

Items 1 through 11.

The information set forth in the Supplement is incorporated herein by reference and amends and supplements information previously incorporated by reference in these Items of the Schedule TO.

On February 1, 2017, the Company issued a press release announcing an increase in the purchase price range to the Minimum Price of RUB 270.00 and the Maximum Price of RUB 290.00 per share of Common Stock and an extension of the Tender Offer for ADSs to 11:59 p.m., New York City time, on February 14, 2017, unless further extended or terminated. At the amended Maximum Price of RUB 290.00 per share of Common Stock to be purchased under the Tender Offer, the Offeror could purchase 16,024,779 shares of Common Stock (including Common Stock represented by ADSs) if the Tender Offer is fully subscribed, which would have represented approximately 0.80 per cent. of the Company’s Issued Share Capital as at January 13, 2017, the latest practicable date for such determination prior to the publication of the Offer to Purchase. At the amended Minimum Price of RUB 270.00 per share of Common Stock to be purchased under the Tender Offer, the Offeror could purchase 17,211,800 shares of Common Stock (including Common Stock represented by ADSs) if the Tender Offer is fully subscribed, which would have represented approximately 0.86 per cent. of the Company’s Issued Share Capital as at January 13, 2017. A copy of the press release is filed as Exhibit (a)(5)(B) to the Schedule TO and is incorporated herein by reference.
