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 41st ordinary session held on Wednesday, 13 May 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 March 2026.

Investments in development contributed to improved operating results and profitability.

The Telekom Slovenije Group continues the implementation of its strategy in 2026, with focused investments in its state-of-the-art infrastructure and through the development of services that are adapted to the needs of users, and is thus consolidating its position as technological leader on the Slovenian market. The Group maintains high standards of reliability and security, and is building a resilient digital environment for users and business partners.

The Telekom Slovenije Group had 2,012,137 retail mobile users as at 31 March 2026, an increase of 2% or 32,276 relative to 31 March 2025. The Group had 322,372 fixed retail broadband and TV connections as at 31 March 2026, an increase of 2% or 4,925 connections relative to 31 March 2025.

Sales revenue totalled EUR 178.7 million, an increase of 4% relative to the same period in 2025. Revenues were up on account of growth in the number of users and higher sales of IT merchandise and services.

Earnings before interest, taxes, depreciation and amortisation (EBITDA) totalled EUR 66.0 million, an increase of 7% or EUR 4.2 million relative to 2025. The EBITDA margin (i.e. EBITDA as a proportion of sales revenue) was 36.9%.

Earnings before interest and taxes (EBIT) amounted to EUR 21.6 million, an increase of 13% 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 16.0 million, an increase of 12% or EUR 1.7 million relative to the same period in 2025.

Active monitoring of geopolitical impacts and financial effects

The Telekom Slovenije Group regularly monitors the development of the geopolitical situation and its potential impact on operations, particular with regard to supply chains, energy prices, the availability of crucial equipment, the implementation of investments, cyber security and cost efficiency.

Based on information available at the beginning of May, the Telekom Slovenije Group assesses that risks are being managed through previously implemented and planned measures, and that there is currently no basis for revising published business objectives or strategies for 2026. The Group will continue to actively monitor the situation, and adjust measures in a timely manner and inform the public of any material impacts in the event of significant changes.

Disproportionate regulation hinders Telekom Slovenije’s development potential

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 slightly less than 29% (source: Q3 2025 AKOS). Telekom Slovenije also has a significantly lower market share than 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 accessible on Telekom Slovenije, d.d.’s website (www.telekom.si) for a period of no less than 10 years from the date of publication.
