ATHENS, Greece - May 09, 2019 - Hellenic Telecommunications Organization SA

(ASE: HTO; OTC MARKET: HLTOY), the Greek full-service telecommunications provider, announced today consolidated results (prepared under IFRS) for the quarter ended March 31, 2019.

Commenting on OTE's 2019 first-quarter performances, Michael Tsamaz, Chairman & CEO, noted: "OTE had a satisfactory start to the year. Trends in Greece are challenging but positive, aligned with what we delivered in 2018-revenues from retail fixed and mobile services were up in all segments, with another strong showing in broadband. In Romania, adjusting for the provisions we took at the end of last year, we are seeing signs of recovery. Group EBITDA was down slightly, as the steady performance in Greece was not enough to offset a decline in Romania, resulting mostly from a high comparison base throughout the first half of last year. While operating metrics remain favorable, new European and local regulations, combined with tough comparisons in the past year, will create some headwinds in coming quarters. This strengthens our resolve to launch a new phase in our transformation, taking advantage of digitalization opportunities, in order to shrink our fixed cost base, face potential challenges, and continue delivering growth."

Mr. Tsamaz added: "Two days ago, we completed the sale of our mobile Albanian subsidiary. Together with our strong cash flow generation, confirmed by the first quarter's on-track delivery, net proceeds from this disposal will ensure a substantial shareholder remuneration."

Outlook

In Greece, where a gradual economic recovery is continuing, OTE expects to further benefit from its investments in advanced data networks in both fixed and mobile, as well as from the customer-centric strategy that has supported its revenue growth in the past years. Revenues in Romania are expected to stabilize following the 2018 one-off items. The Group systematically explores cost-reduction measures to support growth and the necessary investments across its businesses. The Group has launched a number of initiatives to digitize its customer interactions, which will enable significant improvements going forward. In 2019, management continues to expect adjusted Capex of approximately €650mn. Primarily reflecting lower Capex and further Operating Cash Flow improvements, OTE expects 2019 full-year adjusted FCF of approximately €450mn, while reported FCF should reach approximately €350mn.

OTE GROUP HILIGHTS

The OTE Group's consolidated revenues rose slightly to €908.6mn in Q1'19. A solid top-line performance in Greece, up €11.5mn, more than offset a €9.9mn drop in revenues in Romania.

Total Operating Expenses, excluding depreciation, amortization, impairment and charges related to restructuring costs (primarily voluntary leave schemes), amounted to €583.7mn in Q1'19, a 3.6% decrease reflecting the adoption of IFRS 16 (Leases). Before IFRS 16, Operating expenses were essentially unchanged compared to Q1'18. Personnel expenses, totaling €150.5mn, were up 19.5%; this increase primarily reflects their exceptionally low level in Q1'18, when the Company benefited from a one-off reversal of part of its Staff Retirement Indemnity (SRI) provision following the adoption of a new Collective Labor Agreement. Excluding this one-off factor, Personnel expenses were down by 1.2%, reflecting recent voluntary retirement schemes.

In Q1'19, the Group's Adjusted EBITDA before IFRS 16 decreased by 0.9% to €310.6mn, yielding an Adjusted EBITDA margin of 34.2%. In Greece, Adjusted EBITDA before IFRS 16 increased by 1.5% to €284.4mn, and the Adjusted EBITDA margin, at 40.8%, was down 10bps from the level in Q1'18, due to unusually low personnel expense in Q1 last year.

The Group reported Operating profit before financial and investing activities of €133.3mn, compared to €112.2mn in Q1'18. Depreciation and Amortization, totaling €199.9mn, were stable compared to Q1'18.

The Group's Income Tax charge stood at €46.4mn in Q1'19, nearly unchanged from Q1'18.

Adjusted Group profit after minority interests (excluding one-off items) increased by 10.7% to €62.9mn in Q1'19 compared to €56.8mn in Q1'18.

Adjusted Capital Expenditures amounted to €176.1mn in Q1'19, up 6.6%, with investments in Greece and Romania standing at €116.3mn and €59.8mn, respectively.

In Q1'19, the Group's comparable adjusted Free Cash Flow (before IFRS 16) reached €35.6mn, a €22.0mn increase compared to Q1'18, reflecting higher Operating Cash Flow.

The Group's adjusted Net Debt before IFRS 16 was €732.2mn at March 31, 2019, down 2.1% compared to March 31, 2018. The Group's ratio of adjusted Net Debt to 12-month adjusted EBITDA stood at 0.6x.

Note: Adjusted EBITDA (AL) is defined as Adjusted EBITDA deducting the Depreciation of lessee use rights to leased assets and Interest expense of leases.

GREECE

*Including VDSL, Vectoring & Super Vectoring

In Q1'19, the total Greek access market added 6k lines, while OTE's fixed-line operations posted a net loss of 4k access lines.

OTE achieved another quarter of solid net additions in retail broadband customers, totaling 24k since the beginning of the year, to reach 1,920k. Penetration of OTE's high-speed fiber broadband service continued to make progress, with record net additions of 54k in the quarter, supported by the expanding reach of the service and enabling OTE to steadily monetize its investments in infrastructure. At quarter end, OTE's fiber offer had been adopted by 586k subscribers, reaching 30.5% of OTE's total retail broadband base. At March 31, OTE's total number of VDSL/Vectoring activated cabinets amounted to 14.4k, an increase of over 600 units in the quarter. As of March 31, 2019, 65% of OTE fiber broadband customers enjoyed speeds of 50 Mbps or more, as compared to 36% one year earlier. Increasingly, customers are opting for faster speeds, which OTE is making available through its investments.

As of March 31, 2019, the total number of COSMOTE TV subscribers was 540k, up 2.4% year-on-year. In revenue terms TV posted a positive quarter, in a challenging environment, with OTT offerings and piracy on the rise.

OTE is working on an extensive value-enhancement action plan targeting its pre-paid customer base as well as on initiatives aimed at accelerating pre-to post-paid migration. As a result, the total number of pre-paid was sharply reduced due to multiple SIM consolidation, while blended ARPU was up significantly in the quarter. Data traffic continued to increase at a rapid pace, fueled by the growth in active users, higher usage and rising smartphone penetration.

OTE is creating the digital framework to offer customers an enhanced portfolio of services, leveraging its client relationships and retail penetration. OTE recently initiated new services in insurance aggregation and food delivery. The Company is also in the planning phase for the launch of additional e-services.

OTE's digital app has already attracted approximately 2.4 million users, taking advantage of a growing number of features, including the possibility to renew mobile subscriptions or data bundles, pay bills, and tap OTE's new services. The push towards digitalization is driving a new wave of transformation and increasing operational efficiencies.

In Greece, total revenues further increased, reaching €697.0mn, a rise of 1.7%, in Q1'19. Retail fixed services increased by 2.8%, fueled by positive growth in voice, TV and particularly broadband.

Wholesale revenues were up slightly in the first quarter of 2019.

Mobile Service revenues increased by 1.2% in the quarter, driven by revenues from data services, up more than 18%.

Total Adjusted EBITDA Before IFRS 16 in Greece was up 1.5% in the quarter at €284.4mn, yielding a margin of 40.8%.

ROMANIA

*Includes FMC

While demand for legacy technologies in broadband (copper) and TV (DTH) is continuing to shrink, services and offerings relying on the Company's new infrastructure are proving increasingly popular. Through its FMC offering, Telekom Romania further strengthens customer loyalty, and a number of brand and network surveys point to positive trends.

Total revenues for Romania were down by 4.4% to €216.6mn in Q1'19.

Revenues from Retail Fixed Services amounted to €57.8mn, down 12.2%, mainly as a result of lower revenues from fixed voice services, reflecting an unfavorable evolution in both voice ARPU and customer base.

Mobile Service revenues were down 6.6% to €76.2mn in Q1'19. The decrease is chiefly due to the impact of the transition in IT platforms accounted for in Q4'18, which led to a number of disconnections in the latter part of the year. As a result, comps in the first half of 2018 were adversely high. With a normalized comparison base in H2, the Company expects stabilization of its Mobile Service revenue in the second half of the year.

Higher revenues from Wholesale Services primarily reflected the increase in international transit traffic business.

Adjusted EBITDA before IFRS 16 in Romania decreased by 20.8% to €26.2mn in Q1'19. Adjusting for the 2018 base effect the decline would be approximately 7%. The Company is undertaking a series of cost-containment initiatives that are expected to drive efficiencies starting in the second half of this year.

I. ALTERNATIVE PERFORMANCE MEASURES "APMS"

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 CapEx, and Adjusted Free Cash Flow. These are calculated by deducting from the performance measures deriving from directly reconcilable amounts of the Consolidated Statement of Financial Position (Exhibit II), Consolidated Income Statement (Exhibit III) and Consolidated Statement of Cash Flow (Exhibit V), 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 lines "costs related to voluntary leave schemes" and "payment for 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 Group's income statement, while the payment of these expenses is 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 for the calculation of the Adjusted Free Cash Flow and Adjusted Capital Expenditure (CapEx) in order to facilitate comparability with industry peers.

Net debt (before IFRS 16)

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 (before IFRS 16)

Adjusted Net debt 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:

Net Debt & Adjusted Net Debt under IFRS 16

Net debt and Adjusted Net Debt under IFRS 16 are used by management to evaluate the Group's capital structure and leverage taking into account other financial liabilities related to leases. They are defined as Net debt and adjusted Net Debt before IFRS 16 (described above) adding other financial liabilities related to leases as described 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 (Operating profit before financial and investing activities, depreciation, amortization and impairment, costs related to voluntary leave schemes, other restructuring costs and non-recurring litigations)

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 EBITDA before IFRS 16 is used by the management in order to facilitate comparability with prior year's figures. It is defined as deducting from Adjusted EBITDA the lease expense adjustment as well as other lease related adjustments. Adjusted EBITDA before IFRS 16 margin (%) is defined as Adjusted EBITDA before IFRS 16 divided by total revenues.

EBITDA (AL) (Earnings before Interest, Taxes, Depreciation and Amortization after Lease)

EBITD (AL) is intended to provide useful information to analyze the Group's operating performance. EBITD (AL) is defined as EBITDA deducting the depreciation and interest expense of leases, as illustrated in the table below. EBITDA (AL) margin (%) is defined as EBITDA (AL) divided by total revenues.

Adjusted EBITDA (AL) (Operating profit before financial and investing activities, depreciation, amortization and impairment, costs related to voluntary leave schemes, other restructuring costs and non-recurring litigations after Lease)

Adjusted EBITDA (AL) is intended to provide useful information to analyze the Group's operating performance.

Adjusted EBITDA (AL) is defined as EBITDA (AL) adding back costs related to voluntary leave schemes, other restructuring costs and non-recurring litigations, as illustrated in the table below. Adjusted EBITDA (AL) margin (%) is defined as Adjusted EBITDA (AL) divided by total revenues.

Adjusted Profit to owners of the parent

Adjusted Profit for the period 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 period (attributable to owners of the parent) is calculated by adding back to the Profit of the period (attributable to owners of the parent) the impact upon it of the following items: costs related to voluntary leave schemes, net impact from impairments and write offs, reassessment of deferred tax, financial expenses for bond issue and bond buyback premium, reversal of provision related to assets sales, other restructuring costs, non-recurring litigation expenses, effect of changes to tax rate and tax effect from deductible investment losses, as illustrated in the table below:

Capital expenditure (CAPEX) and 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 from Capital expenditure, spectrum payments and capital expenditure payments related to non-recurring litigation 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, excluding net cash flows from operating activities of discontinued operations, after payments for purchase of property plant and equipment and intangible assets (CAPEX) and adding the interest received. 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 accounts in understanding the Group's cash generating performance as well as availability for debt repayment, dividend distribution and own reserves.

Free Cash Flow before IFRS 16 is used by management in order to facilitate comparability with prior year's figures and it is defined as Free Cash Flow adding the Lease repayments.

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.

Adjusted Free Cash Flow before IFRS 16 is defined as Adjusted Free Cash Flow adding the Lease repayments.
