GROUP BUSINESS PERFORMANCE

CONSOLIDATED FINANCIAL HIGHLIGHTS

MTS reported strong Q1 2018 numbers as Group revenue grew 3.1% year-over-year and OIBDA increased 24.6% year-over-year.

Overall, the Group’s performance was mostly driven by Russia, which benefitted from a relatively stronger pricing environment, higher data usage and continued adoption of digital services. The Group witnessed organic growth in each of its markets of operations, but a positive ruble contribution in Armenia was offset by currency weakness in Ukraine. The Group also recognized a small revenue contribution from recent acquisitions.

The adoption of new IFRS 15, Revenue from contracts with customers, had a slightly negative effect on Group service revenue. Sales of goods were particularly robust in Q1 due to growing demand on expensive advanced smartphones, which significantly supported overall Group revenue performance.

Group OIBDA for the quarter jumped 24.6% year-over-year to RUB 52.1 bln. The largest part of this growth was attributable to new IFRS standards. However, excluding the impact of new standards, OIBDA showed an impressive 6.5% increase year-over-year driven by positive revenue dynamics, a stronger pricing environment in Russia, continued cost discipline and retail optimization. The Group OIBDA margin rose to 48.3%, a large portion of the growth of which reflects new IFRS standards.

Group net profit for the first quarter rose 23.6% year-over-year to RUB 15.4 bln. Strong top-line and higher profitability were the key drivers for earnings growth. Negative impact of new IFRS was offset by the revaluation of fair value of financial instruments.

Debt Repayment Schedule (RUB bln)

The Net debt to LTM Adjusted OIBDA ratio(9) remained at a comfortable level of 1.1x, which preserves MTS’s financial strength and its capacity to sustain both investment levels and a strong shareholder return.

On September 6, 2017, MTS launched a program to repurchase shares of common stock and ADSs for an amount of up to RUB 20 bln. MTS also entered into a sale and repurchase agreement with Sistema Finance, a subsidiary of Sistema PJFSC, MTS’s controlling shareholder, to acquire any number of shares proportional to any shares acquired from the market. The Repurchase Plan is executed under Rule 10b5-1 of the Securities Exchange Act of 1934, as amended, and Rule 10b-18 of the Exchange Act and is carried out by the Company’s wholly-owned subsidiary Stream Digital LLC.

In Q1 2018, under the Repurchase Plan, Stream Digital acquired 25,397,204 shares of Common Stock (including shares of Common Stock represented by ADSs) representing 1.27% of share capital issued by MTS. This includes shares of Common Stock acquired from Sistema Finance.

In total, since the launch of the Repurchase Plan, Stream Digital has acquired 69,044,332 shares of Common Stock (including shares of Common Stock represented by ADSs) representing 3.46% of share capital issued by MTS. This includes shares of Common Stock acquired from Sistema Finance under a sale and purchase agreement concluded prior to the launch of the Repurchase Plan.

The Repurchase Plan was the part of the Board of Directors consideration as of April 2016 on spending up to RUB 30 bln over three years to complement MTS dividend payout. Previously, in Q4 2016 and Q1 2017, MTS implemented two modified Dutch auction tenders and acquired in total 35.1 mln shares for approximately RUB 10 bln.

In Q1 2018, capital expenditures totaled RUB 16.7 bln with CAPEX/Revenue ratio 15.4%. Investments grew in Russia as the Company continued its focus on its network construction.  In total, in Q1 2018, the Group built approximately 3,500 base stations across Russia, of which over 2,000 were LTE base stations. The most active network construction was carried out in Moscow and Moscow region, Primorsky krai, Saint-Petersburg and Leningrad region, Samarsky and Ryazansky regions.

Free cash flow totaled RUB 13.9 bln for Q1 2018. This year-over-year decrease from Q1 2017 was largely attributed to the acquisition of several assets, investments in OZON and growth of CAPEX due to network construction.

RUSSIA

In Q1 2018, Russia Revenue increased 4.0% to RUB 101.1 bln supported by mobile service revenue and sales of goods. Meanwhile, fixed-line and integrated services revenue demonstrated a slight decrease. In Q1 2018, MTS reported a marginal revenue contribution in the amount of RUB 0.2 bln from recently acquired assets - e-ticketing operators and Esport club.

Strong consumption of data and other higher-margin products as well as cost optimization initiatives drove profitability.  Russia OIBDA grew 25.6% to RUB 49.6 bln leading to the Russia OIBDA margin of 49.1%.

In mobile business, revenue increased 3.7% year-over-year to RUB 74.3 bln driven by growing data usage and overall continuous strong trends in Russian home market.

By the end of March 2018, the number of subscribers in Russia decreased to 78.1 mln.

MTS’ fixed business continued to demonstrate negative dynamics due to a decrease in the number of fixed-telephony subscribers. In Q1, revenue fell by 0.8% to RUB 15.1 bln.

According to internal estimates, the Company’s B2C broadband and pay-tv market shares in Moscow reached 35.4% and 39.6% respectively by the end of Q1 2018. The number of GPON users reached 1.88 mln as MGTS continues to attract users to its market-leading FTTH GPON network.

Revenue from MTS’ integration business in Q1 decreased slightly to RUB 1.4 bln.

In Q1 2018, MTS started reporting revenue from recently acquired e-ticketing operators and cybersport club as other services revenue.

MTS witnessed a 15.6% year-over-year increase in sales of goods driven by both sales of software products and sales of handsets and accessories. Sales of software products grew due to major enterprise software contracts executed in the reporting period.

According to MTS estimates, the average price of a smartphone sold in Russia in Q1 2018 grew 23.2% year-over-year to RUB 15,325. This growth was largely attributable to strong demand on advanced smartphones stimulated by online loans and installment payment option. In MTS Retail, the number of applications for a loan in Q1 2018 increased by 2.5 times compared to the same period of last year. Every fifth purchase was made on credit. Gross margin in handsets sales reached 14.5%. The fastest growing category of smartphones bought were priced at RUB 30,000 - 40,000. The most popular brands sold were Samsung, Apple and Huawei — together they accounted for roughly 70% (in monetary terms) of the overall smartphone market in Russia.

Handsets and Accessories Sales (RUB bln) and Gross Margin (%)

A year ago, in Q1 2017, MTS optimized its retail chain to roughly 5,700 stores. Since that, the number of stores remained unchanged. Retail optimization positively impacted the Group profitability.

MTS continues to develop its e-commerce. The Company is constantly improving the technological platform of the MTS online shop by expanding its functionality to make online shopping more comfortable. It is also developing trade-in and cash-back options to attract customers and allow them to realize extra financial benefits. MTS online sales reached RUB 1.1 bln in Q1 2018. In addition to this, MTS significantly improved its credit options for online customers and personalized device recommendations through the My MTS app.

By the end of Q1 2018, smartphone penetration on MTS’s network reached 66%. Mobile internet penetration reached 54%.

In cooperation with MTS Bank, the Group continued to improve financial services, one of the key area for MTS. By the end of Q1, the number of MTS Money customers reached 4.6 mln, while total credit portfolio exceeded RUB 17 bln.

UKRAINE

In Ukraine, revenue grew 2.1% year-over-year and reached UAH 2.9 bln for Q1 2018 driven by growth of data consumption.

New IFRS standards positively impacted OIBDA, which increased to UAH 1.5 bln in Q1 2018. On like-for-like basis, excluding the impact of new accounting standards, OIBDA declined 0.4% year-over-year due to the launch of proprietary retail chain in Ukraine in 2017 and the inability to provide mobile communication services in the territories of Ukraine, which are not controlled by the Ukrainian government, for most of the reporting period. OIBDA margin stood at 52.8%.

In January and March 2018, the Group secured 4G licenses as the result of a national auction. At the end of March, the Group launched 4G network in 2.6 GHz bandwidth and in the first month since its launch, over 1 mln Group subscribers started using 4G internet, while the volume of traffic in 4G-covered area grew 60%.

MTS closed the period with 20.7 mln subscribers.

OTHER FOREIGN MARKETS: ARMENIA AND BELARUS

In Armenia, in Q1 2018, revenue increased 6.1% year-over-year to AMD 13.6 bln due to growth in data consumption and sales of handsets. The number of data-users is constantly growing driven by inflow of new, small screen users.  Demand for more expensive devices and a

12

number of marketing initiatives in the reporting period drove revenue from handsets.

OIBDA increased to AMD 6.5 bln, up 22.5% year-over-year as a result of adoption of new IFRS standards and cost optimization. The OIBDA margin reached 47.9%.

Armenia maintained its subscriber base at 2.1 mln.

In Belarus, revenue reached BYN 196.4 mln in Q1 2018, up 15.9% year-over-year driven by growing usage of data and value-added services as well as strong sales of handsets and accessories based on wider choice of assortment and successful marketing initiatives in the reporting period.

Strong revenue performance resulted in double-digit OIBDA growth to BYN 107.9. OIBDA margin in Belarus was 54.9%.

The subscriber base grew to 5.3 mln, supported by further 4G rollout in Belarus.

2018 OUTLOOK

MTS’s financial and operational performance will be impacted by new IFRS standards in 2018:

·                        In January 2014, IFRS 9 and 15 were issued to respectively address accounting for financial instruments and establish principles in recognizing revenue from contracts with customers. These standards came into effect from January 1st, 2018.

·                        In January 2016, IFRS 16 was issued to provide investors with greater clarity regarding the accounting for leases. Although this new standard is effective from January 1st, 2019, MTS has elected to adopt this standard early.

·                        Subsequently in 2018, MTS applied these new standards to its FY 2018 results beginning with Q1 2018 and provide the market 2018 results excluding the impact of IFRS standards for the sake of transparency.

Group Revenue:

For FY 2018, MTS forecasts slightly positive revenue growth, based on the following factors:

·                        Rising data consumption and weaker voice usage, due to voice-data substitution and data adoption;

·                        Competitive dynamics in distribution and reduced SIM-card sales in Russia;

·                        Changes in handset sales due to the optimization of retail distribution channels;

·                        Continued growth in UAH-denominated revenues in Ukraine;

·                        Adoption of new IFRS standards; and

·                        Service revenues in other foreign subsidiaries and currency volatility in relation to the Russian ruble.

Group Adjusted OIBDA:

MTS anticipates that the adoption of new IFRS standards will increase Adjusted OIBDA by an estimated at least RUB 20 bln in 2018. Excluding the impact of new IFRS standards, MTS anticipates a stable outlook for FY 2018 Group Adjusted OIBDA due to the following factors:

·                        Competitive factors and on-going uncertainty over potential optimization of retail distribution;

·                        Anticipated increases in labor costs;

·                        Potential impact of changes to internal roaming policies in Russia;

·                        Expected rise in spectrum costs in Russia;

·                        Market sentiment and the prospective growth in usage of high-value products like roaming;

·                        Developments in foreign subsidiaries, in particular the fate of operations in Turkmenistan; and

·                        Macroeconomic developments and currency volatility throughout our markets of operation.

Group CAPEX:

FY2018 — FY 2019 CAPEX spending estimated to be RUB 160 bln, due to a number of factors:

·                        Partial investments to comply with anti-terror law in Russia;

·                        Further incremental improvements and enhancements to LTE networks;

·                        Implementation of infrastructure and spectrum sharing projects within Russia;

·                        Roll-out of LTE services in Ukraine;

·                        Evolution of commercial 5G solutions and introduction into Russian market; and

·                        Continued investments in digital products and services.

NEW IFRS STANDARDS

IFRS 9, Financial Instruments.

IFRS 9 regulates the classification and measurement of financial assets and liabilities and requires certain additional disclosures. The primary changes relate to the assessment of hedging arrangements and provisioning for potential future credit losses on financial assets as well as recognition of modification gain or loss for all revisions of estimated payments or receipts, including changes in cash flows arising from a modification or exchange of a financial liability, that does not result in its derecognition.

IFRS 15, Revenue from Contracts with Customers.

This standard provides a single, principles-based five-step model for the determination and recognition of revenue to be applied to all contracts with customers. It replaced the existing standards IAS 18, Revenue, and IAS 11, Construction Contracts. The core principle of IFRS 15 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Under the standard, an entity recognizes revenue when (or as) a performance obligation is satisfied, i. e. when “control” of the goods or services underlying the particular performance obligation is transferred to the customer. Far more prescriptive guidance has been added in IFRS 15 to deal with specific scenarios than exists in the current guidance. The main effect of the standard on the Group’s consolidated financial statements related to the deferral of certain incremental costs incurred in acquiring or fulfilling a contract with a customer. Such contract costs are amortized over the period of benefit.

IFRS 16, Leases.

This standard principally requires lessees to recognize assets and liabilities for all leases and to present the rights and obligations associated with these leases in the statement of financial position. The standard also includes new provisions on the definition of a lease and its presentation, on disclosures in the notes, and on sale and leaseback transactions.

Non-IFRS financial measures. This presentation includes financial information prepared in accordance with International Financial Reporting Standards, or IFRS, as well as other financial measures referred to as non-IFRS. The non-IFRS financial measures should be considered in addition to, but not as a substitute for, the information prepared in accordance with IFRS. Due to the rounding and translation practices, Russian ruble and functional currency margins, as well as other non-IFRS financial measures, may differ.

Operating Income Before Depreciation and Amortization (OIBDA) and OIBDA margin. OIBDA represents operating income before depreciation and amortization. OIBDA margin is defined as OIBDA as a percentage of our net revenues. OIBDA may not be similar to OIBDA measures of other companies, is not a measurement under IFRS and should be considered in addition to, but not as a substitute for, the information contained in our consolidated statement of profit or loss. We believe that OIBDA provides useful information to investors because it is an indicator of the strength and performance of our ongoing business operations, including our ability to fund discretionary spending such as capital expenditures, acquisitions of mobile operators and other investments and our ability to incur and service debt. While depreciation and amortization are considered operating costs under IFRS, these expenses primarily represent the non-cash current period allocation of costs associated with long-lived assets acquired or constructed in prior periods. Our OIBDA calculation is commonly used as one of the bases for investors, analysts and credit rating agencies to evaluate and compare the periodic and future operating performance and value of companies within the wireless telecommunications industry. We use the term Adjusted for OIBDA and operating profit where there were items that do not reflect underlying operations that were excluded. OIBDA and Adjusted OIBDA can be reconciled to our consolidated statements of profit or loss as follows:
