Commenting on OTE's 2015 first quarter results, Michael Tsamaz, Chairman & CEO, noted: 'We started the year on another solid quarter in Greece, where fixed-line revenues were up year on year and the drop in mobile was reduced. In Romania and Albania, our performance remained under some pressure from the impact of termination rate cuts. All told, the trend toward stabilization of our revenue base continues, fueled by our offer of new services meeting our customers' needs.'

Mr. Tsamaz added: 'Our cost discipline, strong operating profitability and cash flow generation enabled us to sustain considerable investments in our networks and service offering during the quarter while preserving a particularly healthy financial structure. We expect these trends to continue throughout the year.'

Outlook

For full year 2015, OTE expects the stabilization of its Greek performance in fixed and mobile operations to continue, supported by further expansion of new services, steadier mobile service revenues, as well as a more favorable base of comparison, provided there is a steady path towards recovery in the economy. International operations in Romania and Albania will again be impacted by intense competition and the impact of termination rate cuts. OTE will continue to benefit from cost-containment efforts and will pursue additional initiatives to control its operating expense base throughout its operations. OTE intends to pursue its investments in the infrastructure of Greece and Romania along the lines achieved in 2014, and 2015 CapEx should once again total approximately €0.5bn, excluding spectrum payments. Reflecting lower interest payments and continuing working capital discipline, OTE expects free cash flow to exceed €0.5bn again in 2015.

OTE GROUP HIGHLIGHTS

OTE Group posted a third consecutive quarter of improving top-line trends, recording a 2.4% drop in total consolidated revenues in the first quarter of 2015. Excluding the impact of recent changes in termination rates, mainly in Romania as of April 1, 2014, Group revenues would have been up compared to Q1'14.

For a second consecutive quarter, following seven years of decline, OTE's Greek fixed-line revenues were up slightly, demonstrating the successful turnaround of these operations. Consistent efforts to enhance customer experience and commercial offerings are clearly bearing fruit. In Greek mobile operations, Cosmote Revenues were nearly unchanged, helped by higher handset revenues, while service revenues dropped by 4.9%, a trend similar to previous quarters. In Romania, revenues from fixed-line operations dropped by 5.1% in Q1'15, mainly reflecting the decline of wholesale revenues due to last year's termination rates reduction. Revenues at Telekom Romania Mobile, down 12.7%, would have been up excluding the impact of the steep MTR cuts implemented in April 2014.Similarly, revenues from AMC in Albania, down by 16.4%, would be also up excludingrecent rates cuts. Finally, other revenues were up 13.9% to €118.7mn, chiefly reflecting revenues from the EU-funded project for the expansion of broadband access in rural areas.

Total Operating Expenses, excluding depreciation, amortization, impairments and charges related to voluntary retirement programs and restructuring costs, amounted to €630.9mn in Q1'15, down 1.5% compared to Q1'14. Personnel expenses were down 3.1% in Greek fixed-line operations, despite additional costs of €3.0mn resulting from the transfer to OTE SA of OTE Plus and Voicenet employees, starting this quarter.Group expenses other than personnel costs stood at €456.7mn, down 2.0% in the quarter, mainly reflecting lower interconnection and roaming costs in Greece and Romania.

Group Pro Forma EBITDA declined by 2.2% in the first quarter to €326mn, resulting in a 34.7% pro forma EBITDA margin in the period, up 0.1 percentage point compared to Q1'14. This was largely due to the strong performance of Greek fixed operations.

Financial Expenses were down 17.3% in the quarter to €39.6mn, reflecting lower indebtedness.

Group Adjusted Net Income stood at €53.9mn in Q1'15, down 6.3% compared to the previous year, mainly due to lower EBITDA. Pursuant to a reassessment of the income tax charge for 2014, following clarifications issued by the Greek tax authorities, an €9mn tax charge was included in Q1'15.

Capital Expenditures amounted to €228.2mn in Q1'15 (€159.8mn excluding spectrum payments), reflecting increased investments in fixed and mobile networks in Greece as well as fixed-line infrastructure in Romania together with a €53.9m partial payment for the recently acquired 4G spectrum in Greece and a €14.5m payment related to spectrum acquired in Albania. Capital expenditures in Greek and Romanian fixed-line amounted to €46.0m and €48.6mn respectively. At mobile operations, total Capital Expenditures stood at €133.1m, out of which €68.4mn were related to spectrum payments (€53.9mn in Greece, €14.5mn in Albania).

In Q1'15, the OTE Group posted adjusted Net Operating Cash Flow (including interest received and excluding VRS and restructuring related payments) of €212.8m, up 96.3% compared to Q1'14, as a result of lower working capital, interest and income tax payments.

Adjusted Group Free Cash Flow (including interest received and excluding VRS, spectrum and restructuring related payments) stood at €53mn, significantly improved compared to negative cash flow of €12.5mn in Q1'14.

The Group's Underlying Net Debt amounted to €1.1bn at March 31, 2015, down 28.3% compared to March 31, 2014. The Group's ratio of Underlying Net Debt to 12-month trailing Pro forma EBITDA stood at 0.8x.

In Q1'15, the total Greek access market (OTE active retail lines, Wholesale line rental connections and full LLU subscribers) lost 12k lines. OTE fixed-line operations in Greece posted a net loss of 27k access lines, compared to net line losses of 44k in Q1'14 and 22k in Q4'14. In the quarter, net additions by competitors stood at 15k compared to 35k in Q1'14 and 28k in Q4'14.

In Q1'15, OTE achieved net additions of 27k retail broadband customers, or nearly 46% of total market net additions, bringing the total number of OTE broadband subscribers to 1,394k. OTE's high-speed VDSL broadband service had been adopted by more than 107k subscribers by the end of the quarter. OTE is activating new local exchanges and installing new cabinets at a fast pace to retain customers or upsell to its base and support customer ARPU. OTE experiences gradual pick up in the areas where the service is introduced. VDSL offerings, together with ongoing efforts to improve customer experience, are the major drivers for growing OTE's broadband net additions market share in a highly competitive environment.

OTE also recorded continued satisfactory growth in its TV offering. As of March 31, 2015, total TV subscribers amounted to 367k, an increase of 13k in the quarter.The acquisition of the three-year broadcasting rights for European football UEFA Champions League and UEFA Europa League is expected to support a further increase in the number of OTE TV subscribers in the second half of 2015.

Total Greek fixed-line Operating Expenses, excluding depreciation, amortization and charges related to voluntary retirement programs and restructuring, amounted to €227.8m in Q1'15, unchanged compared to Q1'14. Personnel expenses were down 3.1% in Greek fixed-line operations, despite additional costs of €3.0mn resulting from the transfer to OTE SA of OTE Plus and Voicenet employees, starting this quarter.

As of the end of Q1'15, Cosmote provided mobile telephony services to 7.3mn customers in Greece, down 1.4% from March 31, 2014.

In Q1'15, the rate of service revenue decline at Cosmote Greece was 4.9%, in line with the previous quarter's trends. The mobile termination rate was cut from 1.189 to 1.10 eurocent effective January 1, 2015.

In line with its strategy to fully protect and grow its customer base, focusing on customer experience and high quality of services, Cosmote is investing in maintaining network superiority in terms of coverage and data speeds. In Q1'15, Cosmote further expanded its 4G footprint, now covering more than 70% of the Greek population, significantly ahead of its nearest competitor. The company has already launched a 4G+ mobile broadband network, in selected areas in Athens and Thessaloniki.

Through the OTE-Cosmote-Germanos network, the company supports the EU-funded 'Digital Solidarity' program that provides subsidized hardware (tablets or laptops), internet connections and home training to beneficiaries of the Social Dividend 2014. Cosmote's participation in this program has significantly increased its totalhandset sales for the quarter, amounting to €45.8mn, up 16.5% compared to Q1'14.

Demand for handset mobile data usage continued to grow at a rapid pace in Q1'15, resulting in a near-doubling of Cosmote Greece's data traffic compared to the same quarter last year, reflecting the network's high-speed capabilities as well as growing smartphone uptake.

In Q1'15, Cosmote Greece's blended AMOU increased by +0.6% to 292.8 minutes. Blended ARPU for the same period was €11.1, down 3.0% from Q1'14, supported by an improving mix.

Q1'15 revenues from Romanian fixed-line operations were down 5.1% from Q1'14, mainly due to the termination fee reduction imposed by the regulator. Part of the decline in revenues from retail fixed services was offset by a 9.1% increase in TV revenues, a 22% jump in revenues from ICT projects and a more than doubling in mobile revenues, following the launch of fixed-mobile convergent services in September 2014. The 18.8% drop in wholesale revenues was chiefly due to termination rate cuts. Fixed voice revenues were down 15.1% in the quarter, while revenues from internet services were stable. Compared to March 31, 2014, the total number of Telekom Romania Communications TV subscribers rose by 3.2%. In the first three months of the 2015, the number of customers opting for integrated offers doubled to over 88k.

Total Romanian fixed-line Operating Expenses, excluding depreciation, amortization and charges related to voluntary retirement programs and restructuring declined 3.8% in Q1'15 compared to Q1'14, with personnel expenses down 6.6% compared to last year's quarter.

Service revenues and Pro Forma EBITDA declined by 17.0% and 16.1%, respectively, against Q1'14, mainly reflecting termination rate cuts implemented in April 2014.

Blended ARPU decreased by 14.5% in Q1'15 compared to Q1'14, due to lower incoming ARPU, adversely affected by interconnection rate cuts as well as the aggressive competitive environment, while blended AMOU increased by 1.5%.

At the end of Q1'15, AMC's customer base totaled 2.1mn subscribers, unchanged from the year-earlier level, as the company successfully maintained its position in the highly competitive Albanian telecommunications market.

AMC posted a 9% increase in mobile handset data revenues in Q1'15 compared to the same period last year, fueled by the efficiency of its network covering 96% of the population.

Intensifying competition negatively impacted the Albanian market in Q1'15. In this context, AMC's total revenues declined by 16.4% and service revenues down by 16.5%, compared to Q1'14. Excluding termination rate cuts, AMC's service revenues would have been up.
