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 4th ordinary session held on Wednesday, 11 November 2026, 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 September 2026.

The Telekom Slovenije Group is successfully achieving its established objectives. As at 30 September 2026, the Telekom Slovenije Group had a total of 2,106,063 retail mobile users and 337,691 fixed retail broadband and TV connections.

The Telekom Slovenije Group’s sales revenue totalled EUR 566.7 million, an increase of 4% relative to the same period in 2025. Sales revenue was up primarily on account of growth in the number of users and higher sales of IT services and merchandise at Telekom Slovenije.

Earnings before interest, taxes, depreciation and amortisation (EBITDA) totalled EUR 205.7 million at the Telekom Slovenije Group level, an increase of 7% or EUR 13.1 million relative to the same period the previous year. The EBITDA margin (i.e. EBITDA as a proportion of sales revenue) was 36.3%.

Earnings before interest and taxes (EBIT) amounted to EUR 69.4 million at the Telekom Slovenije Group level, an increase of 9% relative to the same period the previous year. Following the calculation of income tax (including deferred taxes), the Telekom Slovenije Group generated a net profit of EUR 55.4 million, an increase of 16% relative to the same period in 2025.

The Telekom Slovenije Group earmarked EUR 146.6 million for investments during the first nine months of the year. Telekom Slovenije operates the largest fixed and mobile network in Slovenia, with more than 518,000 Slovenian households able to connect 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. The network covers 99.3% of the population with 5G technology, which the Company continues to improve.

Telekom Slovenije is the only operator in Slovenia that is regulated by the Agency for Communication Networks and Services of the Republic of Slovenia (AKOS) in the fixed broadband internet access segment, despite the fact that it is no longer the leading operator in this segment and has a market share of 29% (source: Q2 2026 AKOS). Telekom Slovenije also has a significantly lower market share than most other incumbent European operators. The Company operates in an environment in which excessive and disproportionate regulation hinders its development potential. Telekom Slovenije continues its efforts to achieve balanced regulation that is based on actual market conditions.

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.
