Message from the Chairman & CEO, Kostas Nebis:

"Our quarterly performance demonstrates our continued progress towards our strategic priorities and brings us closer to our 2026 growth target. EBITDA accelerated once again, driven by solid execution across our core businesses-continued momentum in mobile, FTTH, FWA and TV, strong performance in System Solutions, and the ongoing transformation of our operating model. Record FTTH customer additions, together with rising utilization levels, are a clear testament to the benefits of our network expansion and the strong demand for high-quality connectivity. At the same time, we continue to set the benchmark for network excellence. Our latest recognition as "Greece's Fastest Mobile Network" by Ookla for the 10^th consecutive year, is a historic achievement as we are the only operator worldwide to have outperformed the competition for ten years in a row. This recognition is a testament to our sustained investment in network excellence and to our unwavering commitment to delivering a consistently superior experience for our customers.

Our achievements are reinforced by the strength of our financial profile and market position. OTE's recent upgrade to 'A-' by S&P, making us the only company in Greece rated in the 'A' category, is a strong recognition of our resilience and long-term prospects.

Looking ahead, our ambition is to evolve into a digital-first and, over time, AI-native organization, accelerating the integration of AI into our operating model and bringing AI capabilities deeper into our networks. Leveraging the strength of Telekom Group, we remain focused on driving growth, advancing Greece's digital transformation, and creating sustainable long-term value for our shareholders, customers, and society."

Despite the dynamic competition in Greece, OTE remains well positioned to advance its transformation and meet its targets. OTE's leadership in fiber, mobile, TV and ICT, together with a diversified non-core services portfolio, supports its outlook. Its service revenues are expected to continue growing. In the fixed segment, performance is driven by FTTH uptake, FWA momentum, solid TV performance and fiber footprint expansion, with around 2.4 million FTTH homes passed targeted by end-2026. In mobile, growth is supported by further 5G Stand Alone coverage expansion and network superiority, driving customer migrations and rising data usage. In ICT, RRF-funded projects are expected to wind down in H2'26, while private-sector projects increase their contribution. Wholesale is expected to continue declining in the international near-zero-margin segment as certain activities are phased out, while domestic trends remain broadly unchanged. OTE will maintain strict cost discipline and drive efficiencies, supported by growing AI use across IT, network management, call centers and customer operations.

2026 Guidance - Reiterated

Total revenues amounted to €855.8 million in Q2'26, remaining broadly stable year on year, as strong growth in System Solutions, continued growth in mobile service revenues and resilient fixed retail performance offset the anticipated decline in international wholesale revenues, mainly reflecting the planned phase-out of certain activities. Adjusting for this factor revenues remained strong, increasing by 8% year on year.

Adjusted EBITDA (AL) growth accelerated further in the quarter, increasing by 3.0% year on year to €343.3 million. The corresponding margin rose to 40.1%, from 39.0% in Q2'25, primarily reflecting service revenue growth, higher other operating income including approximately €3mn from copper sales, and cost efficiencies, with personnel and marketing expenses declining by approximately €2mn and €7mn, respectively.

Operating profit before financial and investing activities (EBIT) reached €203.3mn in Q2'26, up 5.9% year-on-year, supported by accelerated EBITDA growth in the quarter.

Capex in Q2'26 amounted to €156.9mn, down 7.7% compared to Q2'25. The drop mainly reflects lower TV content spending in the quarter while the Company continues to expand its FTTH network and to rollout the 5G Stand‑Alone (SA) network, which supports the 5G Wifi (FWA) service.

Reported Free Cash Flow (AL) stood at €149.6mn in Q2'26, compared to €160.7mn in the same period last year, as lower capital expenditure was more than offset mainly by timing differences in income tax payments. Free Cash Flow is expected to normalize during the second half of 2026, and the Company remains on track to achieve its full-year targets.

Net Debt stood at €405.3.mn as of June 30, 2026, and the ratio of net debt to 12-month Adjusted EBITDA (AL) stood at 0.3x. In September 2026 a €500mn bond at 0.875% will mature. The Company plans to  refinance the majority of this maturity.

Fixed Business

Retail fixed service revenues maintained a positive trajectory, increasing by 0.3% in Q2' 26. Including Data Communications services, growth stood at 1.4%. Performance was supported by expanded FTTH network availability, strong FTTH customer adoption, alongside solid contributions from TV and Fixed Wireless Access. The UFBB network, commercially launched earlier this year, is also broadening OTE's ability to serve remote areas, expanding access to higher-quality broadband and supporting further fiber uptake. In addition, data communications revenues remained solid during the quarter.

FTTH: OTE continued to accelerate FTTH adoption, recording a new quarterly high of 62k net additions and bringing the total subscriber base to 687k. FTTH penetration within OTE's total broadband base reached nearly 29%, up from 20% a year earlier, while in areas covered by OTE's FTTH network, 54% of eligible OTE retail customers have already migrated to FTTH. Strong demand for higher speeds and reliable connectivity, the continued expansion of OTE's FTTH footprint, and the regulatory framework introduced late last year for the "stop-selling" of FTTC services are driving higher penetration levels.

Increasing FTTH adoption enhances customer experience, supports lower churn and improves cost efficiency, reinforcing the strategic importance of FTTH in sustaining OTE's leading market position. This is further complemented by advanced in-home connectivity solutions, including WiFi Mesh repeaters, which improve coverage and network performance throughout the home and Fiber to the Room (FTTR), which extends fiber connectivity to individual rooms. Together, these propositions strengthen the customer value proposition, support incremental revenues and enhance service differentiation.

The continued growth in FTTH adoption is also driving higher utilization of OTE's fiber infrastructure, with the utilization rate increasing to 41.7%, from 31.3% a year earlier. Approximately 80% of OTE's retail customers are connected through OTE's own network, while 48% of competitors' FTTH subscribers use OTE's infrastructure, up from 46% a year ago. This underscores the increasing strategic importance of OTE's fiber infrastructure in supporting both retail and wholesale FTTH growth.

OTE continued to lead FTTH deployment in Greece, with its footprint reaching 2.2 million homes passed as of June 2026, while the Company targets approximately 2.4 million homes passed by year-end.

Fixed Broadband - FWA: COSMOTE's 5G WiFi service, leveraging OTE's advanced 5G and 5G+ network, continued to gain traction. During the quarter, total Fixed Wireless Access (FWA) uptake accelerated further, recording 19k net additions, bringing the subscriber base at 119k, up from 45k in Q2'25. Increasing contribution supports overall broadband performance by extending high-speed connectivity to underserved areas and enabling OTE to defend its competitive position.

TV: TV revenues continued to record strong growth, while customer additions remained positive despite the second quarter traditionally being a seasonally weaker period for subscriber growth following the conclusion of the main sports season. OTE's TV subscriber base increased by 7.9% year-on-year to 793k as of June 2026. Performance continued to benefit from the enriched sports content portfolio, stricter anti-piracy legislation, and the removal of the tax on pay-TV services.

Mobile Business

Mobile service revenues increased by 2.3% in Q2'26, maintaining solid momentum. Growth was supported by continued strength in postpaid segment, driven by sustained customer migrations from prepaid, and increasing uptake of higher-value propositions.

Postpaid growth - Data usage: The postpaid segment maintained strong momentum during the quarter, recording 62k net additions, the highest quarterly increase in more than 17 years, primarily driven by continued customer migration from prepaid. The total postpaid subscriber base exceeded 3.1 million, representing record year-on-year growth of 8.0%. The ongoing improvement in customer mix, together with the increasing adoption of higher-value propositions, continued to support the blended mobile ARPU. Prepaid customers still accounted for 56% of the total mobile base, above the European average, highlighting further structural potential for customer value creation through continued migration to postpaid.

OTE maintained strong momentum in mobile data usage, with average monthly consumption rising by 20% year on year to 21.0 GB per user in Q2'26. At the same time, 5G device penetration within the active customer base increased by 10 percentage points to 49%.

Network leadership: OTE continued to expand and upgrade its mobile infrastructure, reinforcing its leadership in network quality while supporting growing demand for high-speed connectivity and data services. 5G population coverage exceeds 99%, while 5G+ standalone coverage approximately 84%.

OTE's network leadership continued to be recognized by leading industry benchmarks, including Ookla, umlaut and Opensignal. Recently, OTE was once again recognized as "Greece's Fastest Mobile Network" at the Speedtest Awards^TM, by Ookla^® for the 10^th consecutive year. According to Ookla, COSMOTE TELEKOM is the first mobile network worldwide to achieve this distinction for ten consecutive years, consistently delivering superior customer experience. This distinction adds to eight major recognitions received this year by leading industry benchmarks including Ookla and Opensignal.

Wholesale Business

Wholesale revenues declined by 40.3% in the quarter, mainly reflecting the ongoing phase-out of zero-margin international transit activities, a trend expected to continue through 2026 and 2027. Domestic wholesale revenues remained affected primarily by the continued expansion of competing operators' FTTH networks and the overall structural market trends. This impact was partly offset by growing demand for OTE's wholesale FTTH services, which recorded their highest quarterly net additions to date, further increasing the utilization of OTE's fiber infrastructure by other operators.

Other Revenues and System Solutions

Other revenues increased by 31.2% in the quarter, reflecting strong momentum in Systems Solutions revenues increasing by 52.1% year-on-year. As the Recovery and Resilience Facility (RRF) investment cycle progresses towards completion, demand remained robust, supported by the continued execution of digital transformation projects across both the public and private sectors. OTE strengthened its position as a leading systems integrator, while expanding its portfolio in the private sector, particularly focusing in Cybersecurity, AI and Cloud, while also broadening its participation in EU institutions and other international organizations, supporting sustainable long-term growth.

Standard & Poor's upgrades OTE to "A-" with stable outlook

On June 3, 2026, S&P Global Ratings upgraded OTE's long-term issuer credit rating to A- from BBB+ with a stable outlook. According to the rating agency, the upgrade reflects the recent upgrade of OTE's parent company, Deutsche Telekom AG, OTE's strong financial profile and resilient cash flow generation, as well as the improvement in Greece's economic fundamentals. The rating action further confirms OTE's strong market position, solid credit quality and positive long-term prospects.

IV.  Consolidated Statement of Cash Flows for the quarter and six months ended June 30, 2026 and comparative 2025

The Group uses Alternative Performance Measures ("APMs") to support decision making and performance evaluation. APMs and the respective adjusted measures provide additional insight into the Group's underlying performance and are calculated using amounts directly reconcilable to the Group's Financial Statements, while also taking into account the items below, which, due to their nature, affect comparability. As these costs or payments are of significant size and of irregular timing, it is a common industry practice to be excluded for the calculations in order to enhance comparability with industry peers and facilitate a better understanding of the Group's performance. The APMs should be read in conjunction with and do not replace the directly reconcilable IFRS line items.

1.  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", respectively.

2.  Costs or payments related to other restructuring plans: Other restructuring costs comprise non-ongoing activity-related costs arising from significant changes in the way the Group conducts business. These costs are mainly related to the Group's portfolio management restructuring.

3.  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.

DEFINITIONS AND RECONCILIATIONS OF ALTERNATIVE PERFORMANCE MEASURES ("APMS")

The operations of TELEKOM ROMANIA MOBILE COMMUNICATIONS represented a separate area of operations for the Group and a separate cash generating unit. As a result, its operations for the year 2025 (as of the date of disposal), have been treated as discontinued operations (apart from Balance Sheet as of June 30, 2025).

Net Debt: Net Debt is used to evaluate the Group's capital structure and leverage.
