Key Financial Data

Note: Following TELEKOM ROMANIA MOBILE COMMUNICATIONS (TKRM) disposal, all figures (apart from Balance Sheet of 2024) adjusted to reflect only continuing operations; TKRM has been classified as held for sale and has been treated as discontinued operations in 2025 and 2024.

Message from the Chairman & CEO, Kostas Nebis:

"We are pleased to have successfully completed the disposal of our Romanian operations, a strategic move enabling OTE to focus on domestic growth and continue enhancing shareholder value. In line with our commitments, we declared an extraordinary dividend. In Greece, we have recently reached a significant agreement to further expand our NGA coverage through the partly subsidized concession of UFBB, and undertake the entire project, supporting our strategy to deliver the most extensive and reliable network. Aligned with our ambition to become Greece's leading digital provider, we recently launched the "Magenta AI", bringing the power of AI to customers, a value-enhancing offering to our customers. 

Our Q3 performance was robust across all major segments, with broadband, mobile, and ICT delivering another quarter of growth. I am particularly pleased that our Fixed services remain on positive track for the second quarter in a row against multi-faceted challenges, a direction we anticipate will continue in future periods, supported by the accelerating adoption of FTTH, the success of our Fixed Wireless Access (FWA) and the continuing strong performance of our TV services. Our mobile business continues to deliver solid and sustainable growth, further solidifying our market leadership. Our solid financial results demonstrate the effectiveness of our strategic direction and the value of our integrated service portfolio. As we look forward, we are confident in our ability to lead the market, achieve our full-year targets, generate strong Free Cash Flow, and continue delivering value to our shareholders, customers, and partners".

For the remaining of the year, OTE is well-positioned to maintain its market leadership and meet its strategic goals, thanks to ongoing investments in advanced networks and a strong service portfolio across fixed, mobile, broadband, TV, and bundled offerings. Given the current market dynamics, OTE expects sustained growth, supported by FTTH take up, the new FWA solution, and expanding TV services through enhanced content offerings and stronger anti-piracy measures. OTE remains by far the leader in network reach and is on track to pass approximately 2.1 million homes with FTTH by end of 2025 and following the recent UFBB agreement, approximately 3.5 million by 2030. In Mobile, OTE continues expanding its 5G Stand-Alone (SA) coverage, maintaining its clear advantage in mobile networks. Growth is driven by a strong customer base, initiatives in prepaid, "more-for-more" strategy, while postpaid momentum remains solid. The ICT benefits from ongoing digitization of the country while, though wholesale remains challenging, FTTH wholesale agreements are helping monetize investments and facilitate the transition to fiber. OTE continues to create value for customers and the wider economy, focusing on service excellence, Gigabit leadership, and AI-driven transformation.

2025 Guidance:

After the sale of TELEKOM ROMANIA MOBILE COMMUNICATIONS (TKRM), the company has updated its 2025 guidance to reflect estimates for Greece only:

· Free Cash Flow (FCF): OTE anticipates generating FCF of approximately €530mn in 2025.

· Capital Expenditure (CAPEX): OTE expects CAPEX for 2025 approximately €600mn, focusing on the expansion of its Fiber-To-The-Home (FTTH) infrastructure and the coverage of its 5G Stand Alone (SA) network, which supports Fixed Wireless Access (FWA) service.

· Adj. EBITDA (AL): OTE expects EBITDA growth to reach almost 2%, fueled by solid performance across key services, including mobile, broadband, and TV alongside effective cost management in several areas.

For 2025, "ordinary" shareholder remuneration has been set at €451mn, corresponding to €298mn cash dividend and approximately €153mn in share buybacks. This amount was initially determined based on the expected Free Cash Flow of approximately €460mn for the year, which included the anticipated cash flow deficit from Telekom Romania Mobile (TKRM), as the business remained part of the Group. The targeted €451mn represents roughly 98% of the initial 2025 Free Cash Flow expectation. The dividend per share for 2025 stood at €0.7216, with a final dividend of €0.7415 per share-adjusted for own shares outstanding as of the ex‑dividend date-was paid on July 9, 2025. The share buyback program for 2025 is ongoing, and as of the date of this release, OTE has executed €128mn in share buybacks.

Following the sale of TKRM on October 1, 2025, OTE adjusted its shareholder remuneration to reflect the real impact on the annual Free Cash Flow. As a result of the disposal, OTE will distribute €40mn to shareholders as an extraordinary dividend of €0.10 per share. The extraordinary dividend will be increased accordingly for own shares held by the company that are not entitled to dividends as of the ex-dividend date. The extraordinary dividend will be paid out on December 30, 2025.

Financial Data

Total revenues amounted to €874.0mn in Q3'25, recording strong growth, up 5.0% year on year, driven by sustained growth in mobile, TV, broadband, and ICT services, which more than offset declines in national wholesale and handsets revenues.

· Retail fixed service accelerated its growth trajectory, posting a 1.3% increase in Q3'25 compared to 0.6% growth in the previous quarter, recovering after several quarters of decline. Double digit growth in TV, the positive impact of the Gigabit voucher scheme for FTTH connections, further expansion of FTTH coverage, and the introduction of FWA services this year, are contributing to the improvement in fixed retail revenue.

· Mobile service revenues were up 2.7% in Q3'25, maintaining the positive trend of previous quarters. The postpaid segment continued to grow, fueled by the ongoing pre-to-post migration strategy and the continued uptake of higher-value packages. Additionally, the adjustment of minimum recharge in the prepaid at physical channels contributed to the overall mobile growth, resulting in higher ARPU and further encouraging customers to transition from prepaid to postpaid offerings.

· Wholesale revenues increased by 4.2% in Q3'25, as the increase of low-margin international transit traffic revenues in the quarter offset the continuing drop in national wholesale revenues. National wholesale, as expected, declined, primarily reflecting the ongoing rollout of fiber infrastructure by competing operators across the country. OTE is mitigating part of the impact through its strategic wholesale agreements with key telecommunications players in the market, helping to sustain overall wholesale performance. Approximately €81mn of total wholesale in the quarter reflects international wholesale revenues, which will decline significantly in the course of coming quarters.

· Other revenues increased by 13.6% in the quarter, supported by sustained growth in ICT business. In particular, systems solutions delivered a strong performance with a 37.9% increase. OTE secures multiple contracts, covering managed network services, ERP implementations, fiber optic networks, archive digitization, and the modernization of public services, among other initiatives.

Total Operating Expenses, excluding depreciation, amortization, impairment and charges related to voluntary leave schemes and other restructuring costs, amounted to €500.5mn in Q3'25, higher by €34.3mn year-on-year, reflecting the strong increase in top line.

Adjusted EBITDA (AL) increased by 2.0% to €360.1mn, continuing the positive momentum recorded in prior quarters. The corresponding margin reached 41.2%, compared to 42.4% in Q3'24, primarily due to a higher contribution from lower-margin revenue streams. Alongside revenue growth, ongoing cost efficiencies-particularly in personnel expenses-helped offset certain cost increases during the period.

Operating profit before financial and investing activities (EBIT) stood at €223.5mn slightly down by 0.7% compared to €225.1mn a year ago, mainly reflecting higher amortization of certain intangible assets in the quarter.

Capex in Q3'25 amounted to €149.8mn, slightly lower by €2.4m compared to Q3'24, while total Capex spending in the first nine months reached €437.1mn up from €404.1mn, mainly reflecting FTTH investment plan and the expansion of FWA.

Reported Free Cash Flow (AL) from continued operations stood at €107.6mn compared to €99.9mn in Q3'24, mainly reflecting the increase in EBITDA in the quarter. The Group reported lower income tax outflows and higher working capital requirements as a result of different settlements among income taxes and receivables and advances related to the public sector (see note on Exhibit IV-Cash Flow Statement).

Net Debt stood at €698.1mn as of September 30, 2025, and the ratio of net debt to 12-month Adjusted EBITDA (AL) stood at 0.5x. The Group does not face any significant bond maturity until September 2026 (€500mn 0.875% Notes).

Key Operational Data - Fixed Business

Key Operational Data Mobile Business

FTTH: OTE continued to accelerate the adoption of Fiber-To-The-Home (FTTH) services, achieving solid customer growth of 38K net additions during the quarter. Total FTTH customer base increased to 509K, representing 22% of the Company's total broadband base, while in areas where FTTH network is available, adoption among OTE customers has already reached 47%, demonstrating the effectiveness of OTE's strategy and the growing preference for advanced broadband solutions. The ongoing FTTH uptake reflects steady demand for fast, reliable connectivity, the positive impact of government subsidy programs and the continued expansion of OTE's FTTH infrastructure.

Redemptions of FTTH subsidy coupons continue to grow steadily, while the rising adoption of FTTH continues to boost customer satisfaction, reduce churn, and optimize operating costs, reinforcing the importance of accelerating subscriber growth for OTE's long-term sustainability.

OTE continues to drive the expansion of Greece's FTTH infrastructure, reinforcing its market leadership. By September 2025, the Company had passed almost 2 million homes and businesses with its Fiber-to-the-Home network and remains on track to reach 2.1 million by year-end. This ongoing rollout underscores OTE's dedication to meeting growing connectivity needs and supporting future growth.

The utilization rate of OTE's FTTH infrastructure increased to 33%, up from 26% a year earlier. Of the 509k total OTE FTTH customers, 83% are served by OTE's network, while 47% of competitors' FTTH subscribers rely on OTE's infrastructure, up from 38% the previous year. This highlights the positive impact of strategic FTTH wholesale agreements with key telco players.

Fixed Broadband - FWA: OTE's Fixed Wireless Access (FWA) service, launched in early 2025 over its advanced 5G+ network using slicing technology, continues to expand its footprint in non-fibered areas, offering reliable broadband and voice connectivity. With the addition of voice services and seasonal demand, FWA adoption has gained significant traction, reaching 33k subscribers by the end of the quarter. The growing adoption of Fixed Wireless Access has played a significant role in supporting continued growth in broadband net additions, which reached +1.8k in a traditionally subdued quarter, increasing OTE's total broadband subscriber base to 2.4 million.

TV: Leveraging the sports agreement with Nova, OTE's TV customer base grew 6.7% year-on-year to 758k subscribers as of September 2025, with strong net additions of 23k in the quarter. OTE continues to benefit from ongoing customer expansion and higher ARPU driven by expanded sports content offering. The adoption of anti‑piracy legislation in 2025 and the planned removal of the 10% special tax on pay-TV effective January 1, 2026, will further drive the shift to legitimate services and reinforce OTE's market position.

Mobile: OTE continues to generate robust and sustainable growth, maintaining its strong performance in the postpaid mobile segment, further advancing the positive momentum seen in previous periods. The successful transition from prepaid to subscription plans, along with the optimization of the prepaid portfolio and the growing adoption of high-end offerings and 5G devices continues to yield solid results. In the quarter, OTE recorded strong postpaid additions at +57k, pushing its total postpaid customer base to 3 million, representing a 6.4% increase year-over-year. Strong performance is supported by its network excellence and compelling service offerings. Prepaid customers now represent 58% of the total mobile base, down from 61% a year earlier, underscoring the sustained opportunity for further postpaid expansion.

Demonstrating its ongoing dedication to maintaining its market leadership, OTE is actively investing in the expansion and enhancement of its mobile network. The reliability and resilience of its network not only reinforce its long-term growth trajectory but also demonstrate its commitment to providing an outstanding mobile experience through ongoing innovation and a customer-centric approach. OTE's 5G network now provides coverage to more than 99% of the population, while the deployment of its advanced 5G+ (Stand-Alone) network has made notable strides, reaching over 75% of residents. 5G and 5G+ networks are designed to enhance customer experience through much higher download and upload speeds, exceptionally low latency, improved indoor coverage, and greater network. OTE continues to stand out as the sole provider in Greece with a commercially available 5G Stand-Alone network, highlighting its leadership in bringing innovative connectivity solutions to market.

II. Consolidated Statement of Financial Position as of September 30, 2025 and December 31, 2024

III. Consolidated Income Statement for the quarter and nine months ended September 30, 2025 and comparative 2024

IV.  Consolidated Statement of Cash Flows for the quarter and nine months ended September 30, 2025 and comparative 2024

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 by using the amounts from the Consolidated Statement of Financial Position (Exhibit II), Consolidated Income Statement (Exhibit III) and Consolidated Statement of Cash Flow (Exhibit ΙV) and the below items as well, due to their nature impacting 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")
