ATHENS, Greece - May 11, 2017 - Hellenic Telecommunications Organization SA

(ASE: HTO; OTC MARKET: HLTOY), the Greek full-service telecommunications provider, today announced consolidated results (prepared under IFRS) for the quarter ended March 31, 2017.

Commenting on OTE's first-quarter 2017 results, Michael Tsamaz, Chairman & CEO, noted: "We are facing intensified competition in Greek fixed and further pressure on our customers' disposable income. To contain these factors, our priority is to continuously enhance service offering and customer experience, with solutions specifically tailored to our clients' needs. Once again, our strategy paid off this quarter. Our flagship investments in fiber drove the growth, in broadband revenues and subscriber numbers, offsetting the pressure in voice. In mobile, our focus remains on steadily enhancing the value we provide to our customers with increasingly attractive bundles. This approach is paying off, as data traffic is growing fast and we are monetizing our investments. From a seasonally low quarter, we anticipate a gradual improvement as we leverage the expanding reach of our VDSL network and any improvement in the business environment."

Mr. Tsamaz added: "The digital age in which we live and operate requires speed, efficiency and adaptability. We will continue to improve our networks and services across the board to meet our clients' expectations and reach our sustainable growth targets."

Outlook

OTE expects the fundamental drivers and first-quarter trends to remain largely unchanged for the balance of the year. Broadband demand, notably for higher speeds, is anticipated to strengthen, fueled in particular by the expanded reach of the VDSL offering; conversely, the number of voice-only customers should experience further decline, while growth in mobile data volume and revenues should continue. Performance in Romania and Albania remains challenging. The Group will continue to invest heavily in the technologies, infrastructure and content that enable its customers to succeed across all its markets. OTE maintains the 2017 guidance provided following the release of its 2016 results, namely an adjusted FCF target of €250m, reflecting the increase in Capex to €700mn, as well as exceptional income tax outlays.

OTE Group's consolidated revenues totaled €929.0mn in Q1'17, up 0.1%, driven by growth in both Greek and Romanian Fixed revenues, offsetting pressure in Mobile.

In Greece, revenues rose 0.9% to €685.4mn. The growth stemmed from continuing strong demand for broadband services - despite a new 5% tax implemented in January, a growing number of consumers are adopting COSMOTE's advanced VDSL service. Pay-TV services showed signs of slower growth in what is a seasonally weak quarter, as economic conditions are putting pressure on demand.

In Romania, growth in Fixed revenues reflects solid demand for convergent fixed-mobile bundles, higher wholesale revenues, and a rebound in the ICT business following a slow Q4 last year.

Total Operating Expenses, excluding depreciation, amortization, impairments and charges related to voluntary leave schemes, restructuring and non-recurring litigation costs, amounted to €637.1mn in Q1'17, up 1.5% compared to Q1'16, as stringent cost-control initiatives across the board were offset by higher interconnection as and merchandise costs, supporting revenue driven services.

The Group's adjusted EBITDA was down 1.7% to €304.1m. In Greece, EBITDA was unchanged, yielding an Adjusted EBITDA margin of 38.8%. Adjusted EBITDA was down 4.4% in Romania, reflecting growing competitive pressure in mobile, and down 81.0% in Albania, where operations were impacted by changes in international traffic patterns.

The Group's Income Tax charge stood at €42.9mn in Q1'17, up 14.7%, reflecting higher profit before taxes.

Adjusted Group profit after minority interests (excluding one-off items) stood at €38.2mn in Q1'17, up 4.1% compared to Q1'16.

Adjusted Capital Expenditures amounted to €185.0mn in Q1'17, up 12.3%, reflecting investments in Fixed-line operations in Greece and Romania, amounting to €75.0m and €43.3mn, respectively. In Mobile operations, adjusted Capex in Greece stood at €36.2mn, in Romania at €18.1mn and in Albania at €6.7mn.

In Q1'17, the Group posted negative adjusted Free Cash Flow of €11.3mn, as anticipated, primarily reflecting the increase in Capital Expenditures.

The Group's adjusted Net Debt was €0.6bn at March 31, 2017, down 33% compared to March 31, 2016. The Group's ratio of adjusted Net Debt to 12-month trailing Adjusted EBITDA stood at 0.4x, unchanged from the prior quarter. In the coming 12 months, facing significant redemptions, OTE intends to maintain significant cash reserves.

BREAKDOWN OF GROUP REVENUES

BREAKDOWN OF GROUP ADJUSTED EBITDA

BREAKDOWN PER COUNTRY (After Eliminations)

Renewed macro uncertainty and additional taxation in effect since the beginning of the year impacted consumer spending in Greece in the first quarter of the year. Against this backdrop, OTE's total revenues in Greece were up 0.9%, reflecting the solid performance of fixed-line activities, driven by demand for broadband services, particularly high-speed. Overall, adjusted EBITDA from combined Greek fixed and mobile businesses was unchanged from the first quarter of 2016.

Fixed-Line Operations, Greece

In Q1'17, the total Greek access market (OTE active retail lines, Wholesale line rental connections and full LLU subscribers) lost 1k lines, while OTE's fixed-line operations posted a net loss of 18k access lines, reflecting the intensification of competitive pressure from certain alternative carriers.

OTE achieved net additions of 19k retail broadband customers in Q1'17, representing 55% of total net additions in a market that has experienced its slowest quarterly growth rate in over two years. The total number of OTE retail broadband subscribers rose to 1,655k. Penetration of OTE's high-speed VDSL broadband service continued to expand, with record net additions of 33k in the quarter. At quarter end, OTE's VDSL offer had been adopted by 252k subscribers, or 15.2% of OTE's total retail broadband base, up sharply from 13.4% at 2016 year end. Widespread success in expanding a premium service in a period of significant downward pressure on consumer spending validates OTE's multi-year strategy of investing in VDSL. OTE's wholesale VDSL offering also grew substantially, posting a sequential progression of over 22% in Q1'17. In February, the Regulator finalized the allocation of cabinets for VDSL upgrade to OTE. OTE is pushing ahead with the required investments, to upgrade, within the set timeframe approximately 6k cabinets. This will bring VDSL capabilities to 60% of the population. Consecutively, OTE will upgrade the network with vectoring technology, capable of delivering speeds of 100Mbps.

In Q1'17, the total number of TV subscribers increased by 2k to 505k. While this modest increase largely reflects seasonal factors, pressure on consumer income is also impacting the growth in pay-TV subscriptions, resulting in a marked slowdown compared to recent quarters. To counter these factors, OTE has successfully introduced alternative packs targeting specific customer segments.

OTE achieved satisfactory performances in ICT, largely from private-sector customers, notably in the area of networking.

SUMMARY FINANCIAL DATA - FIXED-LINE OPERATIONS, GREECE

Greek fixed-line operations posted significant year-over-year revenue growth of 3.5% in Q1'17. Revenues from retail fixed services rose 1.5%, supported by strong performances in broadband and TV. The drop in voice revenues was modest, in line with the trends of the past two quarters. These robust performances reflect OTE's investments in high-speed networks and new solutions, improvements in customer experience, and the steady rollout of commercial initiatives aimed at attracting new subscribers. Broadband revenues were boosted by the record VDSL take-up in the quarter, while TV revenues posted another solid increase, though a higher base and additional taxes are impacting the rate of revenue growth.

Total Greek fixed-line Operating Expenses, excluding depreciation, amortization and charges related to voluntary leave schemes, restructuring and non-recurring litigations amounted to €225.5mn in Q1'17, up 2.5% from Q1'16, reflecting higher consumer driven costs supporting activities in shops. Personnel expenses were down 3.4%, reflecting past headcount voluntary leave schemes.

Adjusted EBITDA increased by 4.3% to €168.0mn in Q1'17, boosted by revenue growth and cost-reduction initiatives. As a result, adjusted EBITDA margin in Greek fixed-line operations rose 40 basis points to 42.9% compared to Q1'16, extending the improving trend of the past quarters.

MOBILE OPERATIONS, GREECE

As of March 31, 2017, COSMOTE provided mobile telephony services to 7.7mn customers in Greece, up 3.4% year on year.

Total Mobile revenues dropped 1.2% in Q1'17, extending the improving trends recorded in previous quarters in an environment that remains under pressure.

Service revenues totaled €217.9mn in the quarter, a drop of 1.8%, a marked improvement from prior-year trends.

Data revenues rose by 19% in the quarter, rewarding COSMOTE's focus on providing market-leading coverage and speeds. COSMOTE's 4G and 4G+ footprints now cover approximately 95% and 84% of the Greek population, respectively. About 50% of COSMOTE's data traffic now originates from 4G devices. COSMOTE has introduced a number of targeted offers and pricing solutions to promote data usage among both prepaid and postpaid customers.

In Q1'17, COSMOTE Greece's blended AMOU dropped by 2.2% to 274 minutes, reflecting demand pressures. Blended ARPU for the same period was €10.0, down 5.7% from Q1'16, largely due to pressure in the prepaid market.

Total revenues from Group operations in Romania were down 1.5% to €229.8m, reflecting a solid performance in Fixed, driven by the Company's fixed-mobile convergent solution and demand for ICT projects.

The Group is investing in upgrading its Romanian network infrastructure, including expanding its own 4G coverage and FTTH footprint, which are key elements of its strategy in that market. Capex dedicated to extend 4G coverage will result in providing data access to a wider customer base in a more efficient manner. Similarly, expanded FTTH coverage, currently reaching over 2 million households, is gradually picking up pace with subscribers. Commercially, the focus on convergent bundles, including fixed, mobile and TV, is a significant differentiating factor increasingly appreciated by customers, as evidenced by growing revenues and subscriber numbers.

Combined adjusted EBITDA in Romania posted a limited decline of €1.7m to €37.1m.

Fixed Line Operations, Romania

SUMMARY FINANCIAL & SUBSCRIBERS DATA

*Including FMC

Romania Fixed

In Q1'17, revenues from Romanian fixed-line activities were up 4.6% from the prior-year level, primarily reflecting the company's successful Fixed-Mobile convergent (FMC) solution, customized ICT projects and higher wholesale revenues.

Compared to Q1'16, fixed voice revenues continued their downward trend (-14%) and broadband revenues were down slightly (-1.6%), while TV revenues rose 3%. Compared to March 31, 2016, the number of FMC subscribers increased by 47.4%, the total number of TV subscribers increased slightly (+0.6%), while the number of fixed broadband subscribers shrank by 1.3%.

The increase in Other revenues largely reflects the growth ICT projects delivered to business customers as well as growth in FMC. The year-on-year growth in Other income in Q1'17 is primarily due to disposal of real estate assets.

Total Romanian fixed-line Operating Expenses, excluding depreciation, amortization, and charges related to voluntary leave schemes, restructuring and non-recurring litigations, increased by 6.7% in Q1'17 compared to Q1'16, driven by customer-generated direct costs, notably higher interconnection, mobile handsets and customer premise equipment.

Adjusted EBITDA rose by 4.4% to €21.4m, reflecting efficiency gains, notably from personnel costs, which were down 8%, as well as lower other taxes.

Romania Mobile

At March 31, 2017, Telekom Romania Mobile's customer base totaled 5.0m, down 11.2% from the year-earlier level. Of this total, 32.3% was postpaid. The total number of business customers grew by 2.5% compared to Q1'16, reflecting the Company's targeted offers for professional users and synergies with fixed-line operations.

Blended ARPU, at €4.7, was up 0.3% compared to Q1'16, whereas blended AMOU decreased by 3.8%.

In Q1'17, total Operating Expenses, excluding depreciation, amortization, impairments, charges related to voluntary leave schemes, restructuring costs and non-recurring litigation costs, were down 3.3% compared to the same period last year, mainly due to effective cost control of indirect costs and lower market invest.  

In Q1'17, adjusted EBITDA was down 14.2% compared to the year-earlier period. Working together with the Romanian fixed-line operations, Telekom Romania Mobile is taking steps to improve its performance, including enhanced 4G capabilities, refocused sales efforts, and cost optimization.

As of Q1'17, Telekom Albania's customer base, totaled 1.8m subscribers, up 7% compared to the same quarter last year.

Albania has traditionally relied on international terminating traffic, which has been a profitable stream of business. As terminating traffic has declined, caused by retail price increases in foreign markets, profitability has been eroded, leading to an adjusted EBITDA decline of 81% in Q1'17.

Telekom Albania is taking steps to modify its operating model. As such, it has successfully increased outgoing revenues by 9% and is introducing a number of changes in tariff bundles to partly offset the drop in international interconnection revenues. As a result, a 37.6% increase in mobile data revenue has been achieved, fueled by highly competitive smartphone and data offers.

OTE Group is the largest telecommunications provider in the Greek market and one of the leading telecom groups in Southeast Europe with presence in Greece, Romania and Albania. OTE is among the largest listed companies, with respect to market capitalization, in the Athens Stock Exchange.

V. Consolidated Statement of Cash Flows for the quarter ended March 31, 2017 and comparative quarters

The Group uses certain Alternative Performance Measures ("APMs") in making financial, operating and planning decisions as well as in evaluating and reporting its performance. These APMs provide additional insights and understanding to the Group's underlying operating and financial performance, financial condition and cash flow. The APMs should be read in conjunction with and do not replace by any means the directly reconcilable IFRS line items.

Alternative Performance Measures ("APMs")

In discussing the performance of the Group, "Adjusted" measures are used such as: Adjusted EBITDA and the respective margin %, Adjusted net operating cash flow, Adjusted CapEx, and Adjusted Free Cash Flow. These are calculated by deducting from the performance measures deriving from directly reconcilable amounts of the Financial Statements, the impact of costs or payments related to voluntary leave schemes, costs or payments for restructuring plans and non-recurring litigations and Spectrum acquisitions.

Costs or payments related to Voluntary Leave Schemes

Costs or payments related to Voluntary Leave Schemes comprise the exit incentives provided to employees and the contributions to the social security fund to exit/retire employees before conventional retirement age. These costs are included within the income statement as well as within the cash flow statement line "costs related to voluntary leave schemes". However, they are excluded from the adjusted results in order for the user to obtain a better understanding of the Group's operating and financial performance achieved from ongoing activity.

Costs or payments related to other restructuring plans and non-recurring litigations

Other restructuring costs and non-recurring litigations comprise non-ongoing activity related costs arising from significant changes in the way the Group conducts business and non-recurring legal expenses. These costs are included in the Company's/Group's income statement, while the payment of these expenses are included in the cash flow statement. However, they are excluded from the adjusted results in order for the user to obtain a better understanding of the Group's operating and financial performance achieved from ongoing activity.

Spectrum Acquisition Payments

Spectrum payments comprise the amounts paid to acquire rights (licenses) through auctions run by the National Regulator to transmit signals over specific bands of the electromagnetic spectrum. As those payments are of significant size and of irregular timing, it is a common industry practice to be excluded from the Adjusted Cash Flow generation and Adjusted Capital Expenditure (CapEx) in order to facilitate comparability with industry peers.

Net debt

Net debt is an APM used by management to evaluate the Group's capital structure and leverage. Net debt is defined as short-term borrowings plus long-term borrowings plus short-term portion of long-term borrowings less cash and cash equivalents as illustrated in the table below.

Adjusted Net Debt

Net debt (adjusted) is used by management to evaluate the Group's capital structure and leverage defined as Net debt including other financial assets as they are highly liquidity assets. The calculations are described in the table below:

EBITDA (Earnings before Interest, Taxes, Depreciation and Amortization)

EBITDA is intended to provide useful information to analyze the Group's operating performance. EBITDA is defined as total revenues plus other operating income less total operating expenses before depreciation, amortization and impairment, as illustrated in the table below. EBITDA margin (%) is defined as EBITDA divided by total revenues.

Adjusted EBITDA

Adjusted EBITDA is intended to provide useful information to analyze the Group's operating performance excluding the impact of costs related to voluntary leave schemes, other restructuring costs and non-recurring litigations. Adjusted EBITDA is defined as EBITDA adding back costs related to voluntary leave schemes, other restructuring costs and non-recurring litigations, as illustrated in the table below. Adjusted EBITDA margin (%) is defined as Adjusted EBITDA divided by total revenues.

Adjusted Net Operating Cash Flow

Net Cash from operating activities focuses on the cash inflows and outflows from a company's main business activities (interest expense and income tax paid included on the outflows). Adjusted Net Operating Cash Flow is defined as net cash flows from operating activities adding back payments for voluntary leave schemes, payments for other restructuring plans and non-recurring litigation expenses plus interest received, as illustrated in the table below:

Capital expenditure (CAPEX) & Adjusted Capital expenditure

Capital expenditure is defined as payments for purchase of property plant and equipment and intangible assets. The Group uses capital expenditure as an APM to ensure that the cash spending is in line with its overall strategy for the use of cash. Adjusted capital expenditure is calculated by excluding spectrum payments from Capital expenditure as illustrated in the table below:

Free Cash Flow

Free cash flow is an APM used by the Group and defined as cash generated by operating activities after payments for purchase of property plant and equipment and intangible assets (CAPEX). Free cash flow is intended to measure the cash generation from the Group's business, based on operating activities, including the efficient use of working capital and taking into account its payments for purchases of property plant and equipment and intangible assets. The Group presents free cash flow because it believes the measure assists users of the financial statements in understanding the Group's cash generating performance as well as availability for debt repayment, dividend distribution and own reserves.

Adjusted Free Cash Flow

Adjusted Free Cash Flow facilitates comparability of Cash Flow generation with industry peers. Adjusted Free Cash Flow is useful in connection with discussions with the investment analyst community and debt rating agencies. Adjusted Free Cash Flow is calculated by excluding from the Free Cash Flow (defined earlier) the payments related to voluntary leave schemes, other restructuring plans and non-recurring litigation expenses and spectrum and adding the interest received.

Adjusted Profit to owners of the parent

Adjusted Profit for the year attributable to owners of the parent is intended to provide useful information to analyze the Group's net profitability excluding the impact of significant non-recurring or irregularly recorded items in order to facilitate comparability with previous ongoing performance. Adjusted Profit for the year (attributable to owners of the parent) is calculated by adding back to the Profit of the year (attributable to owners of the parent) the impact upon it of the following items: Costs related to voluntary leave schemes, Net Impact from Impairments, Reassessment of Deferred tax, financial expenses for Bond issue & Bond Buyback premium, Other restructuring costs and non-recurring litigation expenses, as illustrated in the table below:
