Press release

Brussels, 9 February 2026, 08.00 CET – Regulated and inside information

Proximus Group fourth quarter and full-year 2025 financial results will include a non-cash impairment on Proximus Global goodwill

After conducting the review of the carrying value of Proximus Global and its impact on the long-term financial plan, Proximus Group will record a non-cash impairment of goodwill related to the Global segment. The total impairment of EUR 275 million will negatively impact the net income for the fourth quarter and full-year 2025.

As communicated since mid-2025, Proximus Global has seen headwinds in the CPaaS SMS segment intensifying. Industry trends such as the transition from CPaaS SMS to other more cost optimal channels for customers, significantly impacted the SMS-based business. Moreover, organizational changes over the past year and integration challenges impacted the Go-to-Market performance, impeding the topline and margin synergy ambitions.

These headwinds were reflected in the previously reviewed Proximus Global full-year 2025 EBITDA guidance, (declining by c. 10% year-on-year) and the update provided for full-year 2026 (Global EBITDA in the range of EUR 100 million - EUR 130 million).

In view of these challenging and fast-evolving market conditions, the Group has undertaken a strategic realignment with the new Global CEO, Seckin Arikan. Based on the sensitivity analysis done and after reviewing the carrying value of Proximus Global reflecting those headwinds, Proximus Group decided to take a non-cash impairment allocated to the goodwill of Proximus Global of EUR 275 million. This will be reflected in the full year 2025 financial report, issued on 27 February 2026 at 07.00 AM CET.

Proximus will communicate on its revised strategy as part of a comprehensive strategic update for the Proximus Group at the upcoming Capital Markets Day on 27 February 2026.
