Pursuant to the provisions of the Rules of the Ljubljana Stock Exchange and valid legislation, Telekom Slovenije, d.d., with its registered office at Cigaletova ulica 15, Ljubljana, hereby publishes the following announcement:

At its 33rd ordinary session held on Wednesday, 27 August 2025, the Supervisory Board of Telekom Slovenije, d.d. discussed the Unaudited business report of the Telekom Slovenije Group and Telekom Slovenije, d.d. for the period January to June 2025.

The Telekom Slovenije Group is achieving its established objectives and continuing to increase the number of users. As at 30 June 2025, the Telekom Slovenije Group had 4% or 71,388 more retail mobile users and 4% or 13,018 more fixed retail broadband connections than at the end of June 2024.

The Telekom Slovenije Group’s sales revenue totalled EUR 354.2 million, an increase of 2% relative to the same period in 2024. Sales revenue was up on account of growth in the number of users and higher sales of IT services and merchandise.

Earnings before interest, taxes, depreciation and amortisation (EBITDA) totalled EUR 125.8 million at the Telekom Slovenije Group level, an increase of 4% or EUR 4.4 million relative to 2024. The EBITDA margin (i.e. EBITDA as a proportion of sales revenue) was 35.5% at the Group level.

The Telekom Slovenije Group’s earnings before interest and taxes (EBIT) amounted to EUR 39.5 million, an increase of 2% relative to the same period last year. Following the calculation of income tax (including deferred taxes), the Telekom Slovenije Group generated a net profit of EUR 29.6 million, which is comparable with the same period in 2024.

The Telekom Slovenije Group earmarked EUR 88.6 million for investments during the first six months of the year. Telekom Slovenije operates the largest fixed and mobile network in Slovenia, with more than 491,000 Slovenian households connected to its fibre optic network. The Company is laying the foundations for further development by constantly upgrading and modernising the entire network with the latest technologies, strengthening its competitive advantage and putting in place technological support for the continued provision of secure, reliable and modern telecommunications services that meet the latest trends and user expectations. It covers 99% of the population with its 4G network, which it continues to improve, while more than 87% of the population are now able to access the 5G network. Telekom Slovenije will ensure that 99% of the population will be covered by 5G technology in 2025.

Telekom Slovenije is currently the only operator in Slovenia that is regulated by the Agency for Communication Networks and Services (AKOS) in the fixed broadband internet access segment, despite the fact that it is no longer the leading operator in the aforementioned segment, where its market share is just 28% (source: Q1 2025 AKOS). Telekom Slovenije also has a significantly lower market share than other incumbent European operators. A comparative analysis of the regulation of incumbent operators in EU countries indicates a trend of deregulation of telecommunication operators. Telekom Slovenije thus operates in an environment in which excessive and disproportionate regulation hinders its development potential. All current lawsuits filed by operators derive from the misinterpretation of Telekom Slovenije’s position on the market, which is artificially maintained as dominant on account of regulation. Such an environment creates legal uncertainty and increases operating costs, which has a negative impact on Telekom Slovenije’s profit. Telekom Slovenije will continue to pursue its Strategic Business Plan with the aim of providing users state-of-the-art, secure and reliable services. For this reason, Telekom Slovenije will continue its efforts to achieve balanced regulation based on actual market conditions, as this is the only way the Company will be able to exploit its development potential for the benefit of all stakeholders.

The Supervisory Board was briefed on the damage report issued by IPKO Telecommunications LLC in Kosovo on 3 July 2025. The Telekom Slovenije Group and IPKO did not recognise the estimated effects as at 30 June 2025, as that damage event occurred after the aforementioned date. The impairment of the present value of property, plant and equipment and inventories is estimated at EUR 6.3 million, and will be recognised in the income statement under other operating expenses. The Telekom Slovenije Group reported the damage caused by the fire to the insurance company. The reported damage represents an estimate of the replacement value of property, plant and equipment and inventories damaged in the fire.

This announcement will also be available on the company’s website (www.telekom.si) for a period of no less than 10 years from the date of publication.
